[0009] Preferably, the fixed groove is in a C-shaped structure, and the fixed block and the fixed groove are matched with each other.

[0010] Preferably, the sliding block is in a trapezoidal cross section, and the sliding slot and the sliding block are matched with each other.

[0011] Preferably, the mounting groove is in a groove structure, and the mounting groove and the hygroscopic plate are matched with each other.

[0012] Preferably, the inner wall of the bottom end of the device main body is provided with a storage tank, the upper portion of the storage tank is connected with a water pump, the output end of the water pump is connected with a condenser pipe, and the end of the condenser pipe away from the water pump is connected with the inside of the storage tank.

[0013] Preferably, the upper portion of the water pump is provided with a partition plate, and the water pump is composed of multiple U-shaped pipes connected and evenly distributed directly below the partition plate.

[0014] Preferably, the outer wall of the partition plate is evenly provided with through holes, the top end of the partition plate is provided with an exhaust fan, and the air inlet of the exhaust fan is downwardly located directly above the condenser pipe.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] 1. In this utility model, by setting a fixing block, a push rod, and a limiting block, when the moisture-absorbing plate absorbs excessive moisture and needs to be disassembled and replaced, the push rod is pushed. The limiting block and the limiting groove limit the push rod, causing the push rod to move the clamping plate laterally, creating a gap between the clamping plate and the mounting groove. At the same time, the limiting block compresses the spring, and the fixing block is pushed downward by the limiting effect of the sliding groove and the slider, so that the front end of the fixing block is engaged in the fixing groove set at one end of the push rod, fixing the push rod and preventing the clamping plate from returning to its original position due to the elastic force generated by the spring deformation. The clamping plates clamped around the moisture-absorbing plate are removed one by one, and the moisture-absorbing plate is removed from the mounting groove for replacement. After reinstalling the moisture-absorbing plate, the fixing block is slid to stop the push rod from its position, and the clamping plate returns to its original position under the elastic force generated by the spring. The clamping plate clamps and fixes the moisture-absorbing plate around the inner wall of the mounting groove. This structure allows for quick disassembly and assembly of the moisture-absorbing plate, saving manpower, and the moisture-absorbing plate can be reused repeatedly, saving costs.

[0017] 2. In this utility model, the device body, temperature display, and control panel are configured. The temperature display monitors the internal temperature of the device body. When the internal temperature is too high, the control panel turns on the water pump to extract the condensate from the storage tank and transport it to the condenser tube. The condensate then flows back to the storage tank through the other end of the condenser tube, allowing the condensate to be recycled. This rapidly cools the area below the partition. Since the outer wall of the partition has uniformly arranged through holes, the exhaust fan is turned on to draw in the cold air below the partition and blow it into the interior of the device body, rapidly cooling its interior. The hot air rising above the device body is then blown out through the heat dissipation window. Since the exchange of hot and cold air inside may generate moisture that affects the use of the electrical cabinet, the moisture-absorbing plate installed in the mounting slot quickly absorbs the moisture inside the device body. This structure allows the interior of the device body to operate at a low temperature and dry. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: As Figures 1-5 As shown, this embodiment proposes a heat-dissipating electrical cabinet for coal mines, including a main body 1, a temperature display 3, and a slide 5. A sealing door 2 is installed on the outer wall of the main body 1 via bearings. The inner wall of the main body 1 is symmetrically provided with mounting grooves 13. A moisture-absorbing plate 19 is movably installed on the inner wall of the main body 1 via the mounting grooves 13. Limiting grooves 16 are symmetrically provided on the side walls of the main body 1. Push rods 7 are movably installed on the side walls of the main body 1 via the limiting grooves 16. One end of the push rod 7 passes through the inner wall of the main body 1 and is connected to a clamping plate 17. A limiting block 15 is provided in the middle of the push rod 7. A spring 18 is installed on the outer wall of the push rod 7. A fixing groove 14 is provided at the end of the push rod 7 away from the moisture-absorbing plate 19. A slide 5 is provided above the limiting groove 16. A fixing block 6 is movably installed on the side wall of the main body 1 via the slide 5. A slider 20 is provided at one end of the fixing block 6. A temperature display 3 is provided on the outer wall of the top of the main body 1. A control panel 4 is provided below the temperature display 3. A heat dissipation window 21 is provided on the side of the control panel 4.

[0027] In this embodiment, the limiting block 15 is composed of multiple ring structures, and the limiting block 15 and the limiting groove 16 fit together.

[0028] In this embodiment, the fixing groove 14 has a C-shaped structure, and the fixing block 6 fits into the fixing groove 14.

[0029] In this embodiment, the cross-section of the slider 20 is trapezoidal, and the groove 5 matches the slider 20.

[0030] In this embodiment, the mounting groove 13 has a groove structure, and the mounting groove 13 fits into the moisture-absorbing plate 19.

[0031] Specific examples Figure 1 , Figure 4 andFigure 5 As shown, when using this structure, if the moisture-absorbing plate 19 absorbs excessive moisture and needs to be disassembled and replaced, the push rod 7 is pushed. The limiting block 15 and the limiting groove 16 limit the push rod 7, causing the push rod 7 to move the clamping plate 17 laterally, creating a gap between the clamping plate 17 and the mounting groove 13. Simultaneously, the limiting block 15 compresses the spring 18, and through the limiting effect of the sliding groove 5 and the slider 20 on the fixing block 6, the fixing block 6 is pushed downwards, causing the front end of the fixing block 6 to engage with the fixing groove 14 at one end of the push rod 7, thus fixing the push rod 7 and preventing the clamping plate from being clamped. 17 is reset by the elastic force generated by the deformation of spring 18, and the clamping plates 17 clamped around the moisture-absorbing plate 19 are removed one by one. The moisture-absorbing plate 19 is removed from the mounting groove 13 for replacement. After the moisture-absorbing plate 19 is reinstalled, the sliding fixing block 6 is slid to stop the fixed position of the push rod 7, so that the clamping plates 17 are reset by the elastic force generated by spring 18, so that the clamping plates 17 clamp and fix the moisture-absorbing plate 19 around the inner wall of the mounting groove 13. This structure can quickly disassemble and assemble the moisture-absorbing plate 19, saving manpower, and the moisture-absorbing plate 19 can be reused repeatedly, saving costs.

[0032] Example 2: A storage tank 8 is installed on the inner wall of the bottom of the main body 1 of the device. A water pump 12 is connected above the storage tank 8. A condenser pipe 9 is connected to the output end of the water pump 12. The end of the condenser pipe 9 away from the water pump 12 is connected to the inside of the storage tank 8.

[0033] In this embodiment, a baffle plate 10 is installed above the water pump 12, and the water pump 12 is composed of multiple U-shaped tubes connected together and evenly distributed directly below the baffle plate 10.

[0034] In this embodiment, the outer wall of the partition 10 is uniformly provided with through holes, and an exhaust fan 11 is installed at the top of the partition 10. The air outlet of the exhaust fan 11 faces downward and is located directly above the condenser pipe 9.

[0035] Specific examples Figures 1-3 As shown, when using this structure, the internal temperature of the main body 1 is observed through the temperature display 3. When the internal temperature is too high, the water pump 12 is turned on through the control panel 4 to extract the condensate from the storage tank 8 and transport it to the condenser tube 9. Then, the condensate flows back to the storage tank 8 through the other end of the condenser tube 9, so that the condensate can be recycled and the lower part of the partition 10 is cooled down quickly. Since the outer wall of the partition 10 is uniformly provided with through holes, the exhaust fan 11 is turned on to draw in the cold air below the partition 10 and blow it into the interior of the main body 1 to cool down the interior quickly. Then, the hot air rising above the main body 1 is blown out of the exterior of the main body 1 through the heat dissipation window 21. Since the internal exchange of hot and cold air may generate water vapor that affects the use of the electrical cabinet, the moisture-absorbing plate 19 installed in the mounting slot 13 is used to quickly absorb the water vapor inside the main body 1. This structure can keep the interior of the main body 1 at a low temperature and dry operation.

[0036] Working principle: when using, the temperature inside the device body 1 is observed through the temperature display 3, when the internal temperature is too high, the condensate inside the storage tank 8 is pumped out through the control panel 4 and delivered to the inside of the condensing pipe 9, and then flows back to the inside of the storage tank 8 through the other end of the condensing pipe 9, so that the condensate can be recycled, and the lower part of the partition plate 10 is rapidly cooled, since the outer wall of the partition plate 10 is uniformly provided with through holes, the air cooler 11 is started to suck the cold air below the partition plate 10 and blow it into the inside of the device body 1 to rapidly cool the inside of the device body 1, and then the hot air rising above the device body 1 is blown out of the device body 1 through the heat dissipation window 21, since the exchange of cold and hot air inside may produce water vapor affecting the use of the electrical cabinet, the moisture absorption plate 19 installed in the installation groove 13 is used to rapidly absorb the water vapor inside the device body 1, so that the inside of the device body 1 remains low temperature and dry operation, when the moisture absorption plate 19 absorbs excessive water vapor and needs to be disassembled and replaced, the push rod 7 is pushed, the limiting effect of the limiting block 15 and the limiting groove 16 on the push rod 7 is used, the clamping plate 17 is moved transversely driven by the push rod 7, the clamping plate 17 has a spacing with the installation groove 13, the limiting block 15 is used to compress the spring 18, the limiting effect of the slide groove 5 and the slide block 20 on the fixed block 6 is used, the fixed block 6 is pushed down, the front end of the fixed block 6 is clamped into the fixed groove 14 arranged at one end of the push rod 7, the push rod 7 is fixed, the elastic force of the spring 18 is avoided to reset the clamping plate 17, the clamping plate 17 clamped around the moisture absorption plate 19 is removed in turn, the moisture absorption plate 19 is taken out from the installation groove 13 for replacement, after the moisture absorption plate 19 is reinstalled, the fixed block 6 is slid to stop the position of the push rod 7, the clamping plate 17 is reset under the elastic force of the spring 18, the clamping plate 17 clamps the moisture absorption plate 19 around the inner wall of the installation groove 13, the device can rapidly cool the inside of the device body 1, and can maintain a dry environment inside, avoid the water vapor produced by rapid cooling affecting the work inside the device body 1, and the moisture absorption plate 19 can be rapidly disassembled and replaced when it is overloaded.

[0037] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
