Description

TECHNICAL FIELD

[0001] The application relates to the technical field of special instrument manufacturing, in particular to a high-altitude wiring clamp for high-voltage test wiring. BACKGROUND

[0002] The high-altitude wiring clamp for high-voltage test disclosed in the patent application with the announcement number CN221465591U relates to the technical field of special instrument manufacturing, and comprises a spliced insulating rod, a base, a mounting seat and a wiring clamp body.

[0003] When testing various direct-current resistances and loop resistances of primary equipment of voltage levels above 220 kV, in order to ensure the accuracy of test results and prevent the test results from deviating too much due to unqualified test wiring, resulting in misjudgment of test personnel, it is necessary to require that the instrument test clamp is tightly and firmly engaged with the terminal of the tested equipment. However, since these primary equipment is usually high above the ground, wiring during testing is very difficult, and the construction site usually uses a high-altitude wiring clamp or a person-carrying method of a boom truck to solve the wiring problem. However, field practice has proved that using the high-altitude wiring clamp or the person-carrying method of the boom truck has the following shortcomings:

[0004] 1. Although the wiring using the high-altitude wiring clamp is simple and convenient, it is limited by length, structure, strength, control and other factors, and is only suitable for wiring of parallel wiring boards of primary equipment of voltage levels below 220 kV, and is not suitable for vertical wiring boards and primary equipment of voltage levels above 220 kV.

[0005] 2. The wiring using the high-altitude wiring clamp can only be operated manually, and it is difficult to control when the equipment is high or moves, especially when it is used in a live interval, which is extremely dangerous, and the test results are not satisfactory and have large deviations.

[0006] 3. Although the person-carrying method of the boom truck is not limited by voltage levels and equipment height, and the safety is improved, when it is used in a live station, the entry procedures are complicated, the safety requirements are strict, and it is easy to incur fines for violation. The work is affected by the station position, and needs to be frequently moved and adjusted, which is low in work efficiency and high in construction cost.

[0007] In view of the above problems, through continuous exploration and research, we decided to invent an intelligent high-altitude wiring clamp specially used for high-voltage test wiring. SUMMARY

[0020] This invention provides a high-altitude wiring clamp for high-voltage test wiring, which has the following advantages:

[0021] 1. By setting up a light-concentrating mechanism, the annular reflector formed by the closure of each hinge plate reflects external light and directly illuminates the clamping operation area. This avoids the problem of low brightness in the recorded image during the wiring process, which is blocked by the complex intelligent wiring clamp and pressure plate operation, resulting in some parts being dark and some parts being bright.

[0022] 2. By setting up a light-concentrating mechanism, the present invention closes the eight hinged plates into a cover shape when used in some cold regions, concentrating the external sunlight on the operating point, thereby appropriately heating the operating area. Appropriate heating can make the metal wire core at the connection point easier to connect, especially in low temperature or humid environments, where the metal wire core may become stiff or difficult to connect. After heating, the flexibility and plasticity of the metal wire core increase, making it easier for the wiring pliers to clamp and connect.

[0023] 3. This invention sets up a focusing mechanism, and by remotely controlling the electric telescopic rod to push the telescopic sleeve and sliding ring to different distances, the reflector can be positioned at different points to reflect light. This allows for adaptive adjustment of the focus point to suit different operating positions and light directions, making it applicable to a variety of scenarios.

[0024] 4、The present application is provided by setting the light condensing mechanism, so that the intelligent terminal clamp body and the pressing plate are directly opened, and the light condensing operation can be performed without the cover of the hinged plate and the reflecting plate in a place with sufficient brightness, the brightness is opened to the operation area from all directions as much as possible, the operation is more convenient and clear, and in this state, the hinged plate and the reflecting plate are fully opened, which is more conducive to the operation convenience of the intelligent terminal clamp body and the pressing plate, and sufficient expansion operation space is provided.

[0025] 5、The present application is provided by setting the limiting mechanism, the first built-in spring in the telescopic rod pulls the two hinged plates close by a certain elastic force, avoids the problem of inconsistent opening and closing angles and loose closing when the hinged plates are synchronously opened and closed, and ensures the uniformity of closing and opening as much as possible, and also ensures the stability and controllability of the reflecting and lighting effect.

[0026] 6、The present application is provided by setting the auxiliary mechanism, so that the air is stably sprayed through the air jet pipe for a long time, and because the pointing position of the air jet pipe is the operation point, the high-altitude point is blown open by the continuous air jet of the air jet pipes, the cleanliness of the wiring is ensured as much as possible, and the precision and accuracy of the test wiring are ensured, and the air jet pipe can also be stably sprayed for as long as possible, so that the particles are naturally detached in the operation process.
