[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The heat dissipation plate inside the air duct increases the heat dissipation area of ​​the arc suppression coil body, and the circulation mechanism forms air circulation for heat dissipation; the cooling mechanism further reduces the air temperature inside the air duct and improves the heat dissipation effect; the controller can regulate the operation of each component, the shock absorption mechanism reduces the vibration of the device during movement or operation, the movable seat facilitates the movement and position adjustment of the device, and the protective shell provides protection.

[0016] 2. In the vibration damping mechanism, when the device is subjected to vibration or impact, the damper consumes vibration energy through the flow of the internal damping medium, converting kinetic energy into heat energy for dissipation and suppressing the rapid transmission of vibration; the spring, on the other hand, uses its own elastic deformation to absorb and buffer the impact force generated by vibration, converting vibration energy into elastic potential energy for storage, and then slowly releasing it.

The protective cover prevents dust and debris from entering the vibration damping mechanism and ensures its stable operation.

[0017] 3. When the mobile mechanism is running, the motor rotates at high speed after being powered on. The gearbox adjusts the output speed and torque of the motor according to actual needs, reducing the speed and increasing the torque, and transmitting appropriate power to the moving wheels so that the moving wheels can roll on the ground at an appropriate speed and force, thereby driving the device to move and meeting the moving needs of the device under different terrains and working conditions.

[0018] 4. When the circulation mechanism is running, the fan is powered on and generates suction, drawing in outside air through the air inlet. The filter screen at the air inlet filters out dust, debris, and other impurities from the air, preventing them from entering the air duct. Inside the air duct, the air comes into full contact with the heat sink, absorbing the heat emitted by the arc suppression coil body, and then is discharged through the air outlet. The filter screen at the air outlet also prevents impurities from entering the device. This forms a continuous air circulation, constantly carrying away the heat generated by the arc suppression coil body and maintaining its normal operating temperature. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a grounding transformer arc suppression coil assembly includes an assembly 1. The assembly 1 consists of an arc suppression coil body 6, a protective shell 11, and a movable base 15. The arc suppression coil body 6 is installed inside the protective shell 11. An air duct 32 is installed between the arc suppression coil body 6 and the protective shell 11. A heat dissipation plate 31 is installed on the outside of the arc suppression coil body 6 inside the air duct 32. A circulation mechanism 22 is installed inside the air duct 32. A cooling mechanism 12 is installed on one side of the protective shell 11 inside the air duct 32. A controller 2 is installed on the upper side of the protective shell 11. The protective shell 11 is installed on the upper side of the movable base 15. A shock absorption mechanism 29 is installed between the bottom of the protective shell 11 and the upper side of the movable base 15.

[0027] The cooling mechanism 12 consists of a cooling chamber 28 and a semiconductor cooling chip 26. The cooling chamber 28 is installed on one side of the protective shell 11, and the semiconductor cooling chip 26 is installed inside the cooling chamber 28. A second heat-conducting plate 25 is installed on the outside of the cooling chamber 28. One end of the second heat-conducting plate 25 extends into the cooling chamber 28 and contacts the heating end of the semiconductor cooling chip 26. The second heat-conducting plate 25 is also installed on the inside of the cooling chamber 28. One end of the second heat-conducting plate 25 passes through the protective shell 11 and extends into the air duct 32, while the other end of the second heat-conducting plate 25 extends into the cooling chamber 28. When the part is in contact with the cooling end of the semiconductor refrigeration chip 26, the cooling mechanism 12 is working. Based on the Peltier effect, the cooling end of the semiconductor refrigeration chip 26 absorbs heat and lowers its temperature, transferring the heat to the heating end. The second heat-conducting plate 25 inside the cooling cavity 28 conducts the cold energy of the cooling end to the air duct 32, reducing the air temperature inside the air duct 32 and assisting in the heat dissipation of the arc suppression coil body 6. The heat from the heating end is dissipated to the external environment through the second heat-conducting plate 25 on the outside, maintaining the normal operation of the semiconductor refrigeration chip 26 and achieving the cooling of the air inside the air duct 32.

[0028] A protective sleeve 14 is provided on the outside of the shock absorption mechanism 29. The two ends of the protective sleeve 14 are glued to the bottom of the protective shell 11 and the upper side of the movable seat 15.

In the shock absorption mechanism 29, when the device is subjected to vibration or impact, the damper 30 consumes the vibration energy through the flow of the internal damping medium, converting kinetic energy into heat energy and dissipating it, thus suppressing the rapid transmission of vibration. The spring 21 absorbs and buffers the impact force generated by vibration by utilizing its own elastic deformation, converting the vibration energy into elastic potential energy for storage, and then slowly releasing it. The two work together to effectively reduce the impact of vibration on the arc suppression coil body 6 and other components of the device.

The moving mechanism 10 is installed around the base 16, and the power supply 18 is installed inside the base 16. The base 16 is used to install the moving mechanism 10 and the power supply 18.

The moving wheels 17 are installed at the front of the gearbox 20, and the motor 19 is installed at the rear of the gearbox 20. The gearbox 20 is installed inside the base 16. When the moving mechanism 10 is running, the motor 19 is energized and rotates at high speed. The gearbox 20 adjusts the speed and torque output by the motor 19 according to actual needs, reducing the speed and increasing the torque, and transmitting appropriate power to the moving wheels 17 so that the moving wheels 17 can roll on the ground at an appropriate speed and force, thereby driving the device to move and meeting the device's movement needs under different terrains and working conditions.

[0032] A display 3 is mounted on the upper side of the controller 2. Control buttons 5 are mounted on the upper side of the controller 2 next to the display 3. A wireless transceiver 4 is mounted on the upper side of the controller 2 next to the control buttons 5.

A fan 23 is installed inside the air outlet 24. When the circulation mechanism 22 is running, the fan 23 is powered on and generates suction, drawing in external air from the air inlet 13. The filter screen of the air inlet 13 filters out dust, debris, and other impurities from the air, preventing them from entering the air duct 32. The air in the air duct 32 comes into full contact with the heat sink 31, absorbing the heat emitted by the arc suppression coil body 6, and is then discharged through the air outlet 24. The filter screen of the air outlet 24 also prevents impurities from entering the device. This forms a continuous air circulation, constantly carrying away the heat generated by the arc suppression coil body 6 and maintaining its normal operating temperature.

[0034] The working principle and usage process of this utility model are as follows: When the complete set of equipment 1 is running, the arc-suppressing coil body 6 performs the arc-suppressing function inside the protective shell 11. The heat dissipation plate 31 in the air duct 32 increases the heat dissipation area of ​​the arc-suppressing coil body 6. The circulation mechanism 22 draws in air through the air inlet 13, carries away the heat from the heat dissipation plate 31 through the air duct 32, and then discharges it from the air outlet 24, forming an air circulation heat dissipation. The cooling mechanism 12 further reduces the air temperature in the air duct 32 and improves the heat dissipation effect. The controller 2 can regulate the operation of each component. The shock absorption mechanism 29 reduces the vibration of the device during movement or operation. The movable seat 15 facilitates the movement and position adjustment of the device. The protective shell 11 provides protection.
