[0027] Embodiment 2

[0028] like Figure 3-Figure 5 As shown, the invention proposes a self-adaptive explosion-proof self-circulating water cooling device for mining with intelligent detection.

[0029] In an optional embodiment, a plurality of limit columns 19 are connected to the support box 12 , and the height of the limit columns 19 is lower than the height of the pressure sensor 4 ; the limit columns 19 are used to prevent the pressure sensor 4 from being damaged due to excessive mass or pressure of the water tank 13 .

[0030] Embodiment 3

[0031] like Figure 2-Figure 5 As shown, the invention proposes a self-adaptive explosion-proof self-circulating water cooling device for mining with intelligent detection. Compared with the second embodiment, the detailed structure of the moving assembly and the drainage assembly is recorded in this embodiment. The moving assembly also includes a support block 20 and a connecting block 21. The number of the support blocks 20 corresponds to the telescopic device 5. The support block 20 is connected to the support frame 7. The support block 20 is connected to one end of the telescopic device 5. The number of the connecting blocks 21 corresponds to the telescopic device 5. The connecting block 21 is connected to the support frame 6.

[0032] The drainage assembly includes a connecting rod 22 and a plugging assembly. There are multiple connecting rods 22. One end of the connecting rod 22 is rotatably connected to the rotating plate 8 by a pin, and the other end of the connecting rod 22 is rotatably connected to the supporting plate 10 by a pin. The plugging assembly is connected to the supporting plate 10. When the plugging assembly is in use, the two moving ends of the plugging assembly move horizontally to cooperate with the supporting plate 10 to form a cavity for accommodating the cooling pipe 11.

[0033] The blocking assembly includes a blocking plate 23, a guide rod 24, a limit block 25, a sliding block 26 and a second elastic member 27. Two blocking plates 23 are symmetrically arranged. A groove for passing the cooling pipeline 11 is provided on each blocking plate 23. There are multiple guide rods 24. One end of the guide rod 24 is connected to the support plate 10. The other end of the guide rod 24 is connected to the limit block 25. There are multiple sliding blocks 26. The sliding block 26 is slidably connected to the guide rod 24. The sliding block 26 is connected to the blocking plate 23. There are multiple second elastic members 27. The second elastic member 27 is sleeved on the guide rod 24. The second elastic member 27 is located between the sliding block 26 and the limit block 25. The second elastic member 27 is selected from but not limited to a spring.

[0034] In an optional embodiment, the opposite sides of the blocking plates 23 are connected with sealing pads; the sealing pads are selected from but not limited to rubber layers, and the rubber layers can reduce the gaps generated when the blocking plates 23 are spliced;

[0035] In an optional embodiment, a matching plate 28 is connected to the support plate 10, and the matching plate 28 is slidably connected to the sealing plate 23. The matching plate 28 is arranged between the outlet pipe 15 and the return pipe 18; when the sealing plate 23 moves, a gap needs to be opened to move from above the cooling pipe 11. The matching plate 28 can fill the gap on the sealing plate 23, thereby forming an enclosed space to prevent water leakage.

[0036] In summary, when the present invention is used, the inverter body 2 operates normally, and heat is generated during its operation and dissipated from its own shell to the inside of the cabinet 1 for heat dissipation. The surface temperature sensor 3 can detect the temperature of the inverter body 2, and when the temperature reaches the set threshold, a signal is sent to the external controller to control the water pump 14 to start. The water pump 14 in the water tank 13 transports cooling liquid to the cooling pipeline 11 through the outlet pipe 15. The cooling liquid and the inverter body 2 are heat-conducted to reduce the temperature of the inverter body 2. The cooling liquid heated by the high temperature on the surface of the inverter body 2 will continue to flow into the heat exchanger 17. The heat exchanger 17 can reduce the temperature of the cooling liquid. The cooling liquid after the temperature is reduced flows back to the water tank 13 through the reflux pipe 18. The cooling liquid is gradually consumed in the process of continuous circulation of the cooling liquid, cracks are generated in the cooling pipe 11 itself or gaps are generated at the connection points at both ends, resulting in water leakage, and the water level in the water tank 13 drops. The pressure generated by its weight on the pressure sensor 4 becomes smaller. After reaching a predetermined threshold, the pressure sensor 4 will send a signal to the external controller, and the controller will control the circuit to cut off to prevent the liquid from contacting the circuit and causing a short circuit. At the same time, the telescopic device 5 will automatically reset after power failure due to the characteristics of the push rod's own structure. The telescopic end of the telescopic device 5 will gradually move up, driving the connecting block 21, the support frame 6 and the inverter body 2 to move up, so that the inverter body 2 is gradually The inverter body 2 is gradually moved away from the cooling pipe 11 and the ground of the cabinet 1 to prevent the cooling liquid from directly contacting and soaking the inverter body 2. At the same time, the inverter body 2 will contact the two rotating plates 8 during the upward movement. The volume of the inverter body 2 pushes the two rotating plates 8 to rotate with the support shaft 9 as the center. The rotating plates 8 change from a colinear state to a parallel or inclined state, thereby forming an opening on the top of the cabinet 1 to facilitate the removal of the inverter body 2. At the same time, the connecting rod 22 connected to the rotating plate 8 will also move synchronously. The connecting rod 22 moves downward to push the support plate 10 constituting the ground of the cabinet 1 and the cooling pipe 11 connected to the support plate 10 to move downward, thereby causing a drainage gap in the cabinet 1 to prevent the cabinet 1 formed by the support plate 10 and the support frame 7 from The accumulated moisture inside is difficult to discharge, which affects other lines and equipment that are difficult to move. When the support plate 10 moves downward, the blocking plate 23 loses the obstruction of the support frame 7, and the second elastic member 27 drives the sliding block 26 to move linearly along the guide rod 24 through its own elasticity to drive the blocking plate 23 to move. The blocking plates 23 move toward each other and cooperate with the support plate 10 to form a box body, and together with the support plate 10, form a storage space to seal the moisture leaked from the cooling pipeline 11 in the formed storage space, so as to prevent the liquid remaining in the cooling pipeline 11 from continuing to leak after power failure and affecting other equipment that may exist in the surrounding environment. The handle on the blocking plate 23 makes it convenient to pull open the blocking plate 23 to inspect the cooling pipeline 11.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
