Example 1

1 is a structural diagram of a security early warning device for a distribution network line channel according to Embodiment 1 of the present invention. The security early warning device 100 for a distribution network line channel may include a security early warning device body 110, an ultrasonic sensor 120, a control module 130, and an alarm. module 140;

The ultrasonic sensor 120 is located outside the safety early warning device body 110 and is connected to the control module 130 for acquiring the minimum obstacle distance and sending the minimum obstacle distance to the control module 130 .

Wherein, the main body 110 of the safety warning device may be a cuboid, a cylinder, a sphere, or the like. Typically, the security early warning device body 110 may have a circular opening along the axial direction, so the security early warning device body 110 can be sleeved outside the distribution network line, thereby realizing the deployment of the security early warning device 100 to the distribution network line channel. In this embodiment, the material of the safety warning device body 110 is not specifically limited.

The ultrasonic sensor 120 transmits ultrasonic waves to obstacles, detects echoes reflected by the obstacles, and calculates the distance to the obstacles according to the time difference between transmitting ultrasonic waves and receiving echoes. In this embodiment, the obstacles may be large plants such as trees in the distribution network line channel, or objects that temporarily enter the distribution network line channel, for example, tree branches, Temporary passing construction vehicles, etc.

In this embodiment, the safety warning device 100 of the distribution network line channel may be installed at the lowest point of the sag of the distribution network line, and the detection direction of the ultrasonic sensor 120 may be toward the ground. The distance between the device and different obstacles below the line can be obtained through the ultrasonic sensor 120, so as to obtain the minimum distance between the obstacle below and the device, that is, the minimum obstacle distance.

The control module 130 is located inside the safety warning device body 110, and is used to generate a first control signal and send it to the alarm module 140 when the minimum obstacle distance is detected to be less than or equal to the preset distance threshold; wherein, the preset distance threshold can be The preset safety distance. When the minimum obstacle distance is greater than the preset distance threshold, it means that there is no safety risk; when the minimum obstacle distance is less than or equal to the preset distance threshold, it means that the obstacle may threaten the line, that is, there is Security Risk. For example, for a 10 kW distribution line, the preset distance threshold may be 1.5 meters.

The first control signal may be a control signal generated by the control module 130 and directed to the alarm module 140, which is used to control the alarm module 140 to perform an abnormal distance alarm. In this embodiment, when the control module 130 detects that the minimum obstacle distance is less than or equal to the preset distance threshold, a first control signal corresponding to the alarm module 140 may be generated, so as to control the alarm module 140 to perform an abnormal alarm and prompt the patrol inspection There is an abnormal safety distance in the distribution network line channel here.

The advantage of the above setting is that it can realize timely early warning of the security risk of the distribution network line, can avoid the occurrence of security accidents, and thus can avoid economic losses caused by abnormal power failure.

The alarm module 140 is located outside the safety warning device body 110 and is connected to the control module 130 for issuing a first alarm prompt according to the first control signal sent by the control module 130 .

The first alarm prompt may be alarm information corresponding to the abnormal distance, and may include a light alarm (for example, flashing an indicator light, or displaying a light of a specified color) and a sound alarm (for example, playing a preset alarm sound) . In this embodiment, when the alarm module 140 receives the first control signal from the control module 130, it can issue a corresponding alarm prompt to alarm the abnormal distance.

The technical solution of the embodiment of the present invention is to obtain the minimum obstacle distance through the ultrasonic sensor position, and when the control module detects that the minimum obstacle distance is less than or equal to the preset distance threshold, a first control signal is generated; A control signal sends out the first alarm prompt. By using a safety warning device with an ultrasonic sensor, timely and automatic warning can be realized for obstacles near the distribution network line channel that threaten the safety of the line, and the safety of the distribution network line can be improved. And it can reduce the personal safety risk of electric maintenance personnel.

Optionally, as shown in FIG. 2 , the security early warning device 100 of the distribution network line channel may further include a temperature sensor 150;

The temperature sensor 150 is located on the outside of the main body 110 of the safety warning device, and is connected to the control module 130 for collecting the temperature of the distribution network line and sending the temperature of the distribution network line to the control module 130; the control module 130 is also used for detecting the distribution network line when When the temperature is greater than or equal to the preset temperature threshold, a second control signal is generated and sent to the alarm module 140; the alarm module 140 is further configured to issue a second alarm prompt according to the second control signal sent by the control module 130.

The preset temperature threshold may be a preset safe temperature value of the distribution network line. When the temperature of the distribution network line exceeds the safe temperature value, it means that the line has abnormal temperature.

In this embodiment, the security warning device 100 of the distribution network line channel can also monitor the temperature of the distribution network line through the temperature sensor 150 , and send the monitored temperature of the distribution network line to the control module 130 . If the control module 130 detects that the temperature of the current distribution network line is greater than or equal to the preset temperature threshold, it can generate a second control signal to control the alarm module 140 to perform an abnormal temperature alarm, that is, to issue a second alarm prompt.

The second control signal may be a control signal generated by the control module 130 and directed to the alarm module 140 for controlling the alarm module 140 to issue a second alarm prompt. The second alarm prompt may be alarm information corresponding to abnormal temperature. It can be understood that the second alarm information and the first alarm information may correspond to different light alarms (eg, lights of different colors) or voice alarms (eg, different alarm tones).

In this embodiment, by using the temperature sensor 150 to monitor the temperature of the distribution network line in real time, when there is an abnormal temperature alarm, it means that the line is overheated or the load is too large, and the load needs to be adjusted in time, or the connection head of the wire should be detected and checked for the installation position. Whether there is looseness or poor contact. Especially for the wire position with switches and circuit breakers, when abnormal temperature occurs, it is caused by the heating of the connection point. Through timely inspection and maintenance, the risk of power failure caused by the blown switch can be avoided.

The image acquisition module 160 may be a camera. In a specific example, the number of image acquisition modules 160 may be three, corresponding to front, back and bottom respectively (taking any direction of the line direction as the front and the other direction as the back, the vertical downward direction of the line direction is down) in three directions. Through the above settings, shooting in all directions of the distribution network line channel can be achieved, and the comprehensiveness of collecting environmental information can be improved.

In this embodiment, the control module 130 may also send a third control signal to the image acquisition module when detecting that the minimum obstacle distance is less than or equal to the preset distance threshold, and the temperature of the distribution network line is greater than or equal to the preset temperature threshold 160 , to control the image acquisition module 160 to be turned on, and to photograph all the environmental conditions of the distribution network line channel, so as to collect the operation environment image.

The third control signal may be a control signal for the image acquisition module 160 generated by the control module 130 and used to control the image acquisition module 160 to turn on and shoot. In a specific example, if a large vehicle causes the line to be hung up or equipment is damaged, the image of the working environment collected by the image collection module 160 can provide a basis for subsequent hazard processing and evidence search.

Optionally, as shown in FIG. 4 , the alarm module 140 may include an alarm lamp 141 and a sound alarm 142; the alarm lamp 141 is used to light the alarm lamp according to the control signal sent by the control module 130; The alarm sound is played according to the control signal sent by the control module 130 .
