[0003] Due to the limited space in mines, the power modules of mine frequency converters are generally directly fixed on the heat sink base plate. When the power devices or their auxiliary modules are damaged in coal mines, a lot of fault identification and disassembly work is required, making on-site repair very difficult and the repair cycle is long.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a quick-detachable inverter power drive device.

[0018] Reference Figure 1 , Figure 2 and Figure 3 A quick-detachable inverter power drive device includes a mounting base plate 1, a heat dissipation assembly 2, and a mounting housing 3.

[0019] The heat dissipation assembly 2 is mounted on the mounting base plate 1, and the mounting housing 3 is mounted on the heat dissipation assembly 2. The inverter power device 31 is fixedly installed inside the mounting housing 3. Several cable outlets 32 and several cable inlets 33 are provided on the side wall of the mounting housing 3. Fiber optic interfaces 34 and cable interfaces 35 are fixedly installed on the mounting housing 3, and both are electrically connected to the inverter power device 31. An indicator light 36 is fixedly installed on the mounting housing 3, and the indicator light 36 is electrically connected to the inverter power device 31. A heat dissipation vent 37 is provided on the side wall of the mounting housing 3, and a filter screen 38 is provided on the top cover of the heat dissipation vent 37.

[0020] A clamping bolt 39 is provided on the mounting housing 3. One end of the clamping bolt 39 abuts against the mounting housing 3, and the other end of the clamping bolt 39 is connected to the heat dissipation component 2.

[0021] When using the quick-detachable inverter power drive device, the mounting base plate 1 is first fixedly installed on the installation station, and then the mounting housing 3 is installed on the heat dissipation component 2, so as to realize the quick installation and removal of the inverter power device 31, which greatly shortens the maintenance time of the inverter power device 31, reduces the difficulty and risk of operation, and improves the maintenance convenience of the inverter power device 31.

[0022] A handle is fixedly installed on the mounting housing 3 so that workers can hold the mounting housing 3 for installation.

[0023] The inverter power device 31 is electrically connected through the outgoing port 32, the incoming port 33, the fiber optic interface 34, and the cable interface 35 to ensure the normal operation of the inverter power device 31. At the same time, the working status of the inverter power device 31 is displayed through the indicator light 36. When the working status of the inverter power device 31 is abnormal, the indicator light 36 will display it in time so that the inverter power device 31 can be replaced in time.

[0024] Air inside and outside the mounting housing 3 exchanges through the heat dissipation vent 37, allowing the heat generated by the inverter power device 31 to dissipate from the mounting housing 3, thereby reducing the air temperature inside the mounting housing 3 and preventing the inverter power device 31 from overheating due to prolonged operation. This protects the inverter power device 31 and extends its service life.

[0025] Reference Figure 1 and Figure 3 The heat dissipation component 2 includes a heat sink 21, a heat pipe 22, a liquid storage chamber 23, a motor 24, a fan blade 25, a temperature sensor 26, and a controller 27.

[0026] A connecting hole 211 is provided on the heat sink 21, and an installation cavity 212 is provided inside the heat sink 21. The mounting housing 3 is detachably installed on the heat sink 21 by means of bolt connection, and one end of the tightening bolt 39 is threadedly connected to the heat sink 21.

[0027] The heat sink 22 is fixedly installed inside the mounting cavity 212 and is attached to the heat sink 21. The liquid storage cavity 23 is fixedly installed on the mounting base plate 1 and is connected to both ends of the heat sink 22. A liquid pump 231 is installed on the liquid storage cavity 23. Both the heat sink 22 and the liquid storage cavity 23 are filled with coolant.

[0028] By tightening the bolts 39, the mounting housing 3 is tightly attached to the heat sink 21, so that the heat sink 22 can better exchange heat with the mounting housing 3, thereby reducing the air temperature inside the mounting housing 3, protecting the inverter power device 31, and extending the working life of the inverter power device 31.

[0029] The pump 231 operates to draw coolant from the storage chamber 23 into the heat exchange tube 22 and vice versa, thereby replacing the coolant in the heat exchange tube 22 in a timely manner, reducing the temperature of the coolant in the heat exchange tube 22, improving the heat exchange efficiency between the heat exchange tube 22 and the mounting housing 3, and thus improving the heat dissipation efficiency of the heat dissipation assembly 2.

[0030] The motor 24 is fixedly installed inside the mounting cavity 212, and the fan blade 25 is coaxially mounted on the output shaft of the motor 24. The temperature sensor 26 is fixedly installed inside the mounting cavity 212 and is used to detect the temperature inside the mounting cavity 212. The temperature sensor 26, the motor 24, and the liquid pump 231 are all electrically connected to the controller 27.

[0031] When the temperature sensor 26 detects that the temperature inside the mounting cavity 212 has risen and reached the preset temperature, the controller 27 operates and controls the liquid pump 231 and the motor 24 to start. The liquid pump 231 operates and replaces the coolant in the heat sink 22. The motor 24 operates and drives the fan blade 25 to rotate. The rotation of the fan blade 25 accelerates the airflow inside the mounting cavity 212, reduces the air temperature inside the mounting cavity 212 and the coolant temperature inside the heat sink 22, and ensures the heat dissipation efficiency of the heat dissipation component 2 on the mounting housing 3.

[0032] The implementation principle of the quick-detachable inverter power drive device in this application embodiment is as follows: First, the mounting base plate 1 is fixedly installed on the installation station, and then the mounting housing 3 is installed on the heat dissipation assembly 2, realizing the quick installation and removal of the inverter power device 31, greatly shortening the maintenance time of the inverter power device 31, reducing the difficulty and risk of operation, and improving the maintenance convenience of the inverter power device 31. The coolant in the storage chamber 23 is pumped into the heat dissipation pipe 22 by the operation of the liquid pump 231, and the coolant in the heat dissipation pipe 22 is pumped into the storage chamber 23, so that the coolant in the heat dissipation pipe 22 is replaced in a timely manner, reducing the temperature of the coolant in the heat dissipation pipe 22, improving the heat exchange efficiency between the heat dissipation pipe 22 and the mounting housing 3, and thus improving the heat dissipation efficiency of the heat dissipation assembly 2.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
