[0022] Embodiment 2:

[0023] Based on Embodiment 1, the present utility model is as Figures 1 - 3 shown. The inner cavity of the frequency converter body 2 is provided with a first installation groove 8. An internal component 9 is installed in the inner cavity of the first installation groove 8. The left end of the top of the inner cavity of the first installation groove 8 is fixedly connected with a temperature sensor 11.

[0025] The working principle of the present utility model is as follows: Through the electric telescopic rod 22, the plug 19 can be driven to move left and right. When disassembly is required, control the electric telescopic rod 22 to contract, so that the plug 19 leaves the jack 12, and then just lift the frequency converter body 2 upward. Tools are not needed, which is very convenient. When installation is required, insert the plug block 20 into the slot 18, and then control the electric telescopic rod 22 to extend, so that the plug 19 enters the jack 12, thereby playing a fixing role, facilitating people to disassemble and assemble. Moreover, installation and disassembly can be carried out simultaneously at both left and right ends, thus shortening the disassembly and assembly time and improving work efficiency. Through the temperature sensor 11, the temperature in the first installation groove 8 can be detected. When the temperature is too high, turn on the fan 16. By using the fan 16, air can be sent into the air outlet nozzle 17. By using the air outlet nozzle 17, air can be sent into the first installation groove 8, thereby increasing the air flow rate in the first installation groove 8 and quickly discharging the hot air in the first installation groove 8, thus playing a role in heat dissipation. By using the heat dissipation port 10, the pressure stability can be ensured. By using the filter groove 13 and the filter net 14, the air entering the fan 16 can be filtered to prevent external dust from entering the fan 16. By using the dust-proof net 4, a dust-proof effect can be achieved to prevent external dust from entering the first installation groove 8 through the heat dissipation port 10.
