Problems solved by technology
[0002] At present, the scale of substations is on the rise, and the number of operation and maintenance personnel is on the decline. The usual tasks of equipment inspection, operation, and maintenance are relatively heavy. , It takes a long time to travel dozens of kilometers, which greatly delays the best processing time, may bring great safety hazards to the normal operation of primary equipment, and bring huge damage to the social economy and people's lives. loss
Operation and maintenance personnel can solve the above problems to a certain extent by using the old-fashioned high-voltage chamber protection device reset operation vehicle to remotely reset the abnormal signal. The operating vehicle is easy to shift, which greatly increases the difficulty for the operation and maintenance personnel to remotely reset the abnormal signal, resulting in the abnormal signal not being processed in time and quickly

Embodiment
[0022] Example: see figure 1 with 2 , the spring compression return thimble of this embodiment, which includes:
[0023] The main shaft 1 is provided in sequence from the rear end to the front end of the main shaft 1: a clamping piece that is sleeved on the rear end of the main shaft and can move along the axis of the main shaft. The clamping piece is used to clamp the main shaft on the extension rod assembly; the main shaft At least one elastic sleeve 5 and a spring 2 are sequentially sleeved on the front end of the clamping part. The front end of the main shaft 1 is a threaded section and is threadedly connected with an adjustment nut 3. The front end of the main shaft 1 is connected with a functional head 4. The functional head includes a A nut 41 detachably connected to the main shaft, a T-shaped bolt 42 threadedly connected with the nut 41 , and an elastic thimble 43 sleeved on the T-shaped bolt 42 .
[0024] In a specific arrangement, the elastic sleeve 5 and the adjus...
