Description

tapered electric pole buried depth measuring tape

technical field

The utility model relates to a measuring tool, in particular to a tape measure for measuring the buried depth of a tapered electric pole.

Background technique

Most of the poles of low-voltage transmission lines are cement poles made of concrete steel bars. The cement poles are generally in the shape of a conical column with a thin top and a thick bottom, and the diameters of the upper and lower ends are not equal. Electric poles need to use different heights and types of electric poles according to different voltage levels and different erection environments. The models of cement poles generally have lengths of 7.5 meters, 10 meters, 12 meters, 15 meters, and 18 meters. The diameters and tapers of different types of poles are different, so different parts of the tapered poles have different By measuring the diameter or circumference of a certain part of the pole, the distance from here to the lower end of the pole can be calculated. The lower end of the cement pole is buried in the soil, and different burial depths (referred to as burial depth) are required according to the type of the pole. However, after the poles are buried or during the operation of the transmission line, the burial depth of the poles may become shallower or deeper due to various reasons, especially when the burial depth of the poles becomes shallower due to rain erosion or a large amount of soil. It may cause the pole to fall. Checking the buried depth of electric poles is a work that must be paid attention to during line inspection. In the past, there was no quantitative detection method in the inspection of the buried depth of electric poles. The inspectors only made qualitative judgments based on the changes in the terrain, which would produce uncertain errors. Moreover, in the inspection work after bad weather, the defects of the buried depth of the poles cannot be found quantitatively and intuitively.

Utility model content

The technical problem to be solved by the utility model is to provide a portable measuring tool capable of measuring and directly reading the buried depths of various electric poles.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

Tapered electric pole burial depth measuring tape, on the tape is provided with buried depth rulers and standard length rulers corresponding to different types of tapered electric poles, the measurement starting point of the buried depth ruler and standard length ruler is located at one end of the tape measure, the Each buried depth ruler is marked with the pole model mark, the normal buried depth mark, and the lower limit buried depth mark.

The further specific structure of the utility model is that: both the buried depth ruler and the standard length ruler are arranged on the front of the tape; the measurement starting points of the buried depth ruler and the standard length ruler are located at the same end of the tape.

Another specific structure of the present utility model is that: the buried depth ruler and the standard length ruler are respectively arranged on two sides of the measuring tape.

Owing to having adopted above-mentioned technical scheme, the technical progress that the utility model obtains is:

The utility model is only a section of measuring tape, so it is very convenient to carry. By measuring the circumference of the pole close to the ground, the buried depth of the pole can be directly read (that is, the distance from the measurement position to the bottom end of the pole). At the same time, it can also be used as an ordinary tape measure for general length or measurement.

Description of drawings

Fig. 1 is the front structure schematic diagram of tape measure of the present utility model; The left side of tape measure is measuring starting point.

Among them, 1. The model mark of the pole, 2. The standard length ruler, 3. The buried depth zero line, 4. The buried depth ruler, 5. The normal buried depth mark, 6. The lower limit buried depth mark.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Example 1

The tapered pole buried depth measuring tape of the present embodiment, as shown in Figure 1, is a section of tape made of soft material, and the front of the tape is provided with a standard length ruler 2 and a buried depth ruler 4, and a standard length ruler 2 Engraved on the upper part of the front of the measuring tape, the buried depth ruler 4 corresponds to different types of tapered electric poles, including a 7.5m electric pole buried depth ruler, a 10m electric pole buried depth ruler, a 12m electric pole buried depth ruler, and a 15m electric pole buried depth ruler. Commonly used electric pole burial depth measuring rulers such as the depth ruler can also include the ruler of 18 meters or longer electric poles of course. The measuring starting point of buried depth ruler 4 and standard length ruler 2 is positioned at the same end of measuring tape, i.e. the left end. Each burial depth ruler 4 is marked with the pole model mark 1 (such as: 7.5m pole burial depth, 10m pole burial depth, 12m pole burial depth, 15m pole burial depth), normal burial depth mark 5 (such as : 130cm is the normal burial depth of 7.5m poles, 200cm is the normal burial depth of 12m poles...), the lower limit burial depth mark 6 (for example: the minimum burial depth of 10m poles is 1.2m, that is, 120cm, 15m poles The minimum buried depth is 200cm...).

When using the tape measure of this embodiment to measure the buried depth of the electric pole, the left end of a tape measure is the starting point, and the circumference of the electric pole near the ground position is measured with a tape measure. The reading of the intersection point is the buried depth of the electric pole, the smaller the reading, the deeper the buried depth, the larger the reading, the smaller the buried depth, and the reading growth direction of the buried depth ruler 4 is opposite to that of the standard length ruler 2. The position of the buried depth zero line 3 in the accompanying drawings should correspond to the circumference value of the lowermost end of the electric pole of the corresponding model.

Example 2

The difference between this embodiment and embodiment 1 is that the buried depth gauge 4 and the standard length gauge 2 are respectively arranged on the front and back sides of the measuring tape. When arranged like this, the buried depth ruler 4 and the standard length ruler 2 can not interfere with each other, can be used alone, and can also be used in conjunction with both sides. And the measuring starting point of depth ruler 4 and standard length ruler 2 can no longer be the same end of measuring tape.
