when the angle between the lever arm and the horizontal plane is 65-75 degrees, the long arm section is separated from the driving limiting seat, the short arm pad is contacted with the push disc, and the outer friction disc is separated from the inner friction disc.
When the overhead cable (hereinafter referred to as cable) needs to be deiced, an operator (usually a power grid worker) carries the separated upper sleeve and lower sleeve, firstly climbs on the power tower for supporting (namely supporting and fixing) the cable, then clamps the cable by using the upper sleeve and the lower sleeve, and connects and fixes the upper sleeve and the lower sleeve by using screws to form the ice breaking holding sleeve. Then the operator returns to the ground, starts the fuel engine of the ice-breaking vehicle, the fuel engine drives the ice-breaking vehicle to move forward, the operator holds the cart handrail and moves forward along the vehicle body, and in the process of moving forward, the operator can guide the moving direction through the cart handrail (the path is not necessarily straight, and the moving direction of the vehicle body is along the direction of the cable on the whole, but is not necessarily completely parallel to the cable). The ice breaking vehicle can drive the ice breaking embracing sleeve to move forward together through the stay cable spring and the long stay cable (the stay cable spring is in a stretched state, and the front end of the embracing sleeve faces the moving direction), so that ice and snow on the cable can be scraped.
At ordinary times, the clutch spring always pushes against the outer friction disc and tightly presses the outer friction disc against the inner friction disc, a fuel engine (common gasoline engine, diesel engine and the like) drives the front wheel to rotate through the transmission of structures such as a common linkage clutch and the like to drive the vehicle body to move forward, and the vehicle body drives the ice breaking sleeve to move forward along the cable through the stay spring and the long stay cable (at the moment, the lever spring has small stretching degree and does not work on the common linkage clutch). Because the normally-linked clutch is always in a linked state (the outer friction disc and the inner friction disc are in contact and have pressure, and the inner friction disc can drive the outer friction disc to rotate together), the ice breaking sleeve can basically and continuously remove ice and snow on the cable. Generally, the accumulated snow on the cable is relatively easy to remove due to the loose snow, but a small portion of the accumulated snow is thick and hard ice (hereinafter referred to as "ice which is difficult to remove easily"), and cannot be easily removed. When the ice breaking holding sleeve contacts ice blocks which are difficult to remove easily, the vehicle body moves forwards, so that the stay cable spring is further stretched, the lever spring starts to be stretched obviously, the short arm pad contacts the push disc and pushes the push disc to move towards the direction far away from the outer friction disc, the outer friction disc and the inner friction disc are driven to separate, the vehicle body loses advancing power, the ice breaking holding sleeve, the long stay cable and the stay cable spring cannot be subjected to larger pulling force, and the cable, the ice breaking holding sleeve, the long stay cable, the stay cable spring and other structures can be protected. After an operator finds that ice blocks which are difficult to break easily are encountered, the fuel engine can be shut down (flameout), then the ice blocks are broken manually (for example, the ice blocks are broken by knocking a knocking rod like a traditional ice breaking mode), then the fuel engine can be started continuously, the vehicle body can be driven to move forward, and the ice breaking cover is used for deicing continuously.

The valve seat comprises a valve tube 651, a far limiting ring 652 arranged at one end of the valve tube and a near limiting ring 653 arranged at the other end of the valve tube, the axis of the valve tube is parallel to the axis of the clutch shaft, the valve core comprises a piston body 661 in sliding sealing fit with the valve tube and an outer compression rod 662 penetrating through the near limiting ring, the valve spring penetrates through a central hole of the far limiting ring, an inner connecting channel is arranged on the piston body, the length direction of the outer compression rod is parallel to the sliding direction of the piston body, one end of the outer compression rod is arranged outside the valve body, the other end of the outer compression rod is connected with the piston body, and a long arm pad 444 used for contacting the outer;
when the lever arm is in a vertical position, the piston body contacts the near limiting ring, the far limiting ring, the piston body, the external compression rod, the long arm section and the driving limiting seat are sequentially arranged along the length direction of the clutch shaft, a gap is formed between the long arm pad and the external compression rod, the valve air inlet hole is communicated to the valve exhaust hole through an internal connecting channel, and the valve air guide hole is sealed by the piston body;
when the piston body contacts the far limiting ring, the angle between the lever arm and the horizontal plane is 70 degrees, the long arm pad contacts the external pressure rod, the valve air inlet is communicated to the valve air introducing hole through the internal connecting channel, and the valve air outlet is sealed by the piston body.
At ordinary times, the piston body contacts the limit ring, and tail gas generated by the fuel engine is exhausted into the atmosphere through the main exhaust pipe, the valve air inlet hole, the internal connecting channel, the valve exhaust hole and the valve exhaust pipe.
As mentioned above, sometimes "ice cubes that are difficult to remove easily" are encountered. In the scheme, when the 'ice blocks which are difficult to remove easily' are encountered, as mentioned above, the outer friction disk and the inner friction disk are driven to separate at a certain moment, and the vehicle body loses the advancing power, so that an operator can hold the cart handrail and keep the vehicle body still without shutting down the fuel engine. The reason is that, except that the short arm pad contacts the push disc and pushes the push disc to move towards the direction far away from the outer friction disc, the long arm pad also contacts the outer pressed rod and pushes the outer pressed rod to move towards the direction far away from the outer friction disc, and finally the piston body contacts the far spacing ring, at this time, tail gas (tail gas temperature is higher) generated by the fuel engine enters the hot ring pipe through the main exhaust pipe, the valve air inlet hole, the inner connecting channel, the valve air guide hole, the valve air guide pipe, the drainage metal corrugated pipe and the air connecting pipe and is sprayed out from the hot spray pipe, and the hot tail gas sprayed out from the hot spray pipe rapidly melts and softens the ice blocks which are difficult to clean, so that after a short period of time, the ice blocks which are difficult to clean are melted and softened under the action of the pull rope spring and the lever spring (the pull rope spring and the lever spring begin to shrink), the ice is broken to hold the front end of, The softened ice blocks which are difficult to remove easily are removed, and once the lever spring contracts and resets, the clutch lever and the push disc also reset, the normally-linked clutch returns to the linked state, and the vehicle body can continue to move forward.
It should be noted that the heat insulation protection tube can prevent excessive heat loss (heat dissipation) at the position of the drainage metal corrugated tube and can also prevent scalding of an operator. The reason why the switching is carried out when hot gas (tail gas) is needed is that the tail gas is guided to the hot ring pipe and the hot spray pipe at any moment, because the more pipelines the tail gas flows away when other conditions are the same or basically the same, generally speaking, the larger the exhaust resistance is, the lower the thermal efficiency of the fuel engine is, the higher the oil consumption is (the exhaust resistance is larger, the unsmooth exhaust is caused, the intake air is influenced, the combustion efficiency is influenced, carbon deposition is increased, and various problems are caused, which is common knowledge in the field of fuel engines).
