In fact, when the temperature in the fixed box 4 is low, the friction disc 16 is abutted against the upper side of the electric actuator 3, when wind blows to the fan blade 18, the fan blade 18 can be driven to rotate, the driving shaft 24 is driven to rotate, the connecting block 13 is driven to rotate through the first connecting rod 14 and the second connecting rod 15, the friction disc 16 is driven to rotate, the friction disc 16 and the electric actuator 3 rotate relatively, the temperature of the electric actuator 3 is increased through a friction heat generating mode, the electric actuator 3 is prevented from being frozen in cold weather, the abnormal work of the equipment is avoided, the reliability of the equipment is improved, when the temperature in the fixed box 4 is too high, the control assembly is driven to work, the through pipe 9 is prevented from being blocked, the air can be conveniently flowed, meanwhile, the moving unit can be driven to work, the connecting block 13 is driven to move upwards, and the friction disc 16 is separated from the electric actuator 3, thereby make friction disk 16 can not be through the friction themogenesis to can not heat for electric actuator 3, when friction disk 16 rotated, can carry out the work of stirring to the air in the fixed box 4 for the flow of air, make external air can get into the inside of fixed box 4 through siphunculus 9, realize giving the radiating function of cooling down in the fixed box 4, prevent in the fixed box 4 overheated and increase the probability that electric actuator 3 damaged, thereby improved the reliability of equipment. Through the photovoltaic panel 29, the work of solar power generation can be carried out, so that energy can be provided for equipment, the electric quantity used by the electric valve can be reduced, the energy is saved, the environmental protection performance of the equipment is improved, when the temperature in the fixing box 4 is too high, the through pipe 9 cannot be blocked, meanwhile, the friction disc 16 is separated from the electric actuator 3, and the friction disc 16 continues to rotate, so that the air in the fixing box 4 is stirred, the air flow is accelerated, the outside air can enter the inside of the fixing box 4 through the through pipe 9, the function of cooling and radiating in the fixing box 4 is realized, meanwhile, part of the air can be guided into the hose 21 through the branch pipe 20, the air is sprayed out from the nozzle 22, the function of blowing air to the photovoltaic panel 29 is realized, the function of removing dust from the photovoltaic panel 29 is realized, the dust is prevented from covering the photovoltaic panel 29, and the influence on the power generation efficiency is avoided, thereby the reliability of equipment has been improved, when the air flows in branch pipe 20, can drive swing unit work for nozzle 22 can make a round trip rock, thereby has enlarged nozzle 22's jet-propelled scope, has promoted the effect of removing dust, and the practicality is higher.

Compared with the prior art, the electric valve for pipeline transportation can heat the electric actuator 3 through the anti-freezing mechanism, thereby avoiding the electric actuator 3 from being frozen in cold weather and preventing the equipment from working abnormally, thereby improving the reliability of the equipment, compared with the prior anti-freezing mechanism, the anti-freezing mechanism can realize the purpose of radiating heat for the electric actuator 3 when the electric actuator 3 is overheated, realizing the function of adjusting temperature, reducing the probability of damage of the electric actuator 3, having higher practicability, and providing energy for the equipment through the energy-saving mechanism, thereby reducing the electric quantity used by the electric valve, thereby saving energy, improving the environmental protection property of the equipment, compared with the prior energy-saving mechanism, the energy-saving mechanism can also realize the purpose of removing dust for the photovoltaic panel 29, enlarging the dust removal range and improving the dust removal effect, the practicality is higher.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
