[0002] A frequency converter is a device that applies microelectronics technology and frequency conversion technology. A mine-used frequency converter is a special frequency converter produced for mine equipment. It changes the alternating current signal with a fixed frequency input from the power supply into an alternating current signal with an adjustable frequency, so as to achieve precise control of the motor, improve the working efficiency and operation stability of the equipment.

[0003] When the existing mine-used frequency converter is installed, it is fixed by bolts. This traditional fixing method is not only time-consuming and laborious, but also the bolts are made of metal materials, which will rust after long-term use. When disassembling, the screws and bolts are prone to slipping threads, increasing the difficulty of disassembly, resulting in a slow disassembly rate of the frequency converter. Moreover, the frequency converter generates a large amount of heat during use, and too high a temperature inside the frequency converter is likely to cause damage to some components of the control board, thus affecting the stability and function of the frequency converter. Summary of the Invention

[0004] The purpose of the utility model is to provide a mine-used frequency converter which is convenient to install and fix, and can solve the problems that when installing and disassembling the frequency converter, the bolts are inconvenient to disassemble, resulting in a low disassembly efficiency of the frequency converter, and the frequency converter generates a large amount of heat during use, which is likely to cause damage to some components, thus affecting the stability and function of the frequency converter.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0026] A mine inverter that is convenient for installation and fixation, including an inverter main body 1. Side plates 2 are respectively fixedly connected to the left and right sides of the inverter main body 1. A plurality of through holes are opened in the inner cavity of the side plate 2. A fixed seat 3 is arranged on one side of the inverter main body 1. Heat dissipation holes 12 are opened at the bottom of the fixed seat 3. A plurality of fixed rods 9 are fixedly connected in the inner cavity of the fixed seat 3. Extrusion springs 16 are respectively fixedly connected to the four corners of the inner cavity of the fixed seat 3. A clamping plate 7 is fixedly connected to the bottom of the extrusion spring 16.

[0027] By adopting the above technical solution, when an operator wants to install the inverter main body 1, the operator passes the fixed rod 9 through the through hole of the side plate 2 correspondingly, and pushes the inverter main body 1 to move towards the inner cavity of the fixed seat 3. The heat dissipation holes 12 can reduce the temperature in the inner cavity of the fixed seat 3, so that the top and bottom of the inverter main body 1 gradually squeeze the clamping plate 7, making the clamping plate 7 gradually compress the extrusion spring 16 until one end of the clamping plate 7 corresponds to the front end of the inverter main body 1. The compressed extrusion spring 16 of the clamping plate 7 pushes and clamps on the outer surface of the inverter main body 1, fixing the inverter main body 1 in the inner cavity of the fixed seat 3, which is convenient for the operator to install the inverter main body 1.

[0028] Specifically, asFigure 3 , Figure 4 As shown in Figure 4 , a fixing cylinder 13 is fixedly connected to the middle of the inner cavity of the fixing base 3. Extension holes 19 are respectively formed at the top and bottom of the fixing cylinder 13. A rotating rod 14 is rotatably connected to the inner cavity of the fixing cylinder 13. One end of the rotating rod 14 penetrates through the fixing base 3 and extends to the outside of the fixing base 3. A handle 8 is fixedly connected to one end of the rotating rod 14. Extension springs 18 are respectively fixedly connected to the top and bottom of the rotating rod 14. A connecting block 17 is fixedly connected to the top of the extension spring 18.

[0029] By adopting the above technical solution, when an operator wants to disassemble the frequency converter main body 1, the operator rotates the handle 8, so that the handle 8 drives the rotating rod 14 to move. When the top of the connecting block 17 corresponds to the extension hole 19, the compressed extension spring 18 pushes the connecting block 17 out of the outside of the fixing cylinder 13, so that the connecting block 17 pushes the clamping plates 7 at the top and bottom to compress the extrusion springs 16 upward and downward respectively, so that the clamping plates 7 no longer fix the frequency converter main body 1, which is convenient for the operator to take out the frequency converter main body 1 from the inner cavity of the fixing base 3. The operation is simple and fast, significantly reducing the installation and disassembly time, improving the work efficiency, and also reducing the labor intensity of the staff.

[0030] Specifically, as shown in Figure 1 , Figure 3 , Figure 5 As shown in Figure 5 , a temperature controller 10 is fixedly connected to the inner wall of the fixing base 3. A water collecting tank 6 is fixedly connected to one side of the fixing base 3. A water pump 5 is fixedly connected to one side of the water collecting tank 6. One end of the water pump 5 is fixedly connected to a water pipe 15. The other end of the water pipe 15 penetrates through the fixing base 3 and extends into the inner cavity of the water collecting tank 6. The water pipe 15 is distributed in an S shape in the inner cavity of the fixing base 3. An impeller 20 is rotatably connected to the middle inner cavity of the water pipe 15. A rotating shaft 4 is fixedly connected to the bottom of the impeller 20. The bottom of the rotating shaft 4 penetrates through the top of the inner cavity of the fixing base 3 and is fixedly connected to a fan 11.

[0031] By adopting the above technical solution, the water collecting tank 6 can collect the rainwater falling on rainy days. When the frequency converter main body 1 generates a large amount of heat during operation, the temperature in the inner cavity of the fixing base 3 gradually rises. The temperature controller 10 detects that the temperature in the inner cavity of the fixing base 3 rises, so that the water pump 5 sucks the water flow in the inner cavity of the water collecting tank 6 into the water pipe 15. After the water flow passes through the inner cavity of the fixing base 3, it flows back into the water collecting tank 6 again. The S-shaped bent water pipe 15 can increase the flow distance of the water flow. While cooling the inner cavity of the fixing base 3 through the water pipe 15, the flowing water flow drives the impeller 20 to rotate, and the impeller 20 drives the fan 11 at the bottom to rotate, cooperating with the water pipe 15 to dissipate heat from the frequency converter main body 1 and prevent the components from being damaged.

[0032] Working principle: When the operator wants to install the inverter main body 1, the operator passes the fixing rod 9 through the through hole of the side plate 2 correspondingly, and pushes the inverter main body 1 to move towards the inner cavity of the fixing seat 3. The heat dissipation holes 12 can reduce the temperature in the inner cavity of the fixing seat 3, so that the top and bottom of the inverter main body 1 gradually squeeze the clamping plate 7, causing the clamping plate 7 to gradually compress the compression spring 16 until one end of the clamping plate 7 corresponds to the front end of the inverter main body 1. The compressed compression spring 16 of the clamping plate 7 pushes the clamping plate 7 to be clamped on the outer surface of the inverter main body 1, fixing the inverter main body 1 in the inner cavity of the fixing seat 3. When the operator wants to disassemble the inverter main body 1, the operator rotates the grip 8, causing the grip 8 to drive the rotating rod 14 to move. When the top of the connecting block 17 corresponds to the extension hole 19, the compressed extension spring 18 pushes the connecting block 17 out of the outside of the fixing cylinder 13, so that the connecting block 17 pushes the clamping plates 7 at the top and bottom to compress the compression spring 16 upward and downward respectively, so that the clamping plate 7 no longer fixes the inverter main body 1, facilitating the operator to take out the inverter main body 1 from the inner cavity of the fixing seat 3. When a large amount of heat is generated during the operation of the inverter main body 1, the temperature in the inner cavity of the fixing seat 3 gradually rises. The temperature controller 10 detects the increase in the temperature in the inner cavity of the fixing seat 3, causing the water pump 5 to suck the water flow in the water collection tank 6 into the water pipe 15. After the water flow passes through the inner cavity of the fixing seat 3, it flows back into the water collection tank 6. While cooling the inner cavity of the fixing seat 3 through the water pipe 15, the flowing water flow drives the impeller 20 to rotate, and the impeller 20 drives the fan 11 at the bottom to rotate, cooperating with the water pipe 15 to dissipate heat from the inverter main body 1 and preventing the components from being damaged.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
