Description

Technical Field

[0001] This invention belongs to the field of substations, specifically relating to a box-type substation with a bottom water-proof sealing structure. Background Technology

[0002] Traditional box-type substations often use simple grilles or louvers for bottom ventilation openings, relying solely on natural ventilation for heat dissipation. They lack effective sealing designs, making it easy for rainwater or water from low-lying areas to seep into the box through the ventilation openings, causing electrical equipment to become damp and short-circuit. Although some are equipped with dustproof nets, their waterproof performance is poor and cannot prevent backflow of water. Furthermore, it is difficult to balance sealing and ventilation. Excessive sealing can affect heat dissipation, while open ventilation openings can cause water immersion failures, making it difficult to meet the safe operation requirements of humid and flood-prone environments.

[0003] Patent CN223713352U discloses a water-resistant American-style substation, including a substation with gates rotatably connected to both ends of its front side. A waterproof plate is fixed to the outside of the substation, and a motor protective cover is fixed to the upper side of one side. A rubber frame is fixed to the front of the substation, and the surface of the rubber frame has grooves. Magnets are evenly adhered to the surface of the grooves on the rubber frame. A rubber retaining ring is fixed to the surface of the gate, and a metal sheet is disposed inside the retaining ring. This patent allows for water immersion protection through the L-shaped waterproof plate at the heat dissipation holes on the surface of the substation and the internal rubber frame. The locking and sealing of the rubber retaining ring on the surface of the substation door improves the seepage prevention effect of the American-style substation. Although the above-mentioned device solves the above-mentioned problems, it is difficult to simultaneously seal the side or other openings of the box-type substation to prevent water seepage during the sealing and water-proofing process. At the same time, it is difficult to provide multi-layer sealing for the bottom opening of the substation to prevent water seepage. This makes it easy for rainwater to enter the equipment in heavy rain, affecting the normal operation of the box-type substation. Therefore, a heat preservation device for frost protection and pest and disease prevention for forest seedling cultivation is proposed to solve the above-mentioned problems. Summary of the Invention

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

When the device is in use, it is located in rainy weather. The water temperature sensor monitors the depth of rainwater accumulation at the bottom of the base 1 in real time. When the water level rises to a dangerous level, the water temperature sensor sends a signal to the cylinder 6, which then activates. The extension end of the cylinder 6 moves the fixed plate 7 downwards. This movement of the fixed plate 7 moves the pull rod 10 downwards. During this movement, the pull rod 10 adjusts its angle simultaneously. This adjustment also moves the slider 9 along the guide rail 8. The inner wall moves, and the movement of slider 9 will drive the fixed plate 11 to move synchronously. The movement of fixed plate 11 will drive the elastic telescopic rod 12 to move. The movement of elastic telescopic rod 12 will drive the sealing plate 13 to move. After moving a certain distance, sealing plate 13 will contact ventilation plate 14 and close the ventilation and heat dissipation port of ventilation plate 14. At the same time, sealing plate 13 can waterproof seal the opening of ventilation plate 14, effectively preventing water from entering the bottom of the device and improving the water immersion sealing effect of the device. The inner wall of the base 1 is provided with a sealing mechanism 4 for sealing the opening, and a pressing mechanism 5 for improving the sealing strength. The pull rod 10 is rotatably connected to the circumferential surface of the fixed plate 7, and the fixed plate 7 is used to drive the pull rod 10 to rotate and move. The sealing plate 13 is in contact with the substation body 2. The ventilation plate 14 is located on the movement trajectory of the sealing plate 13, and the sealing plate 13 is used to seal the ventilation plate 14. A water level sensor is provided at the bottom of the ventilation plate 14. The sealing plate 2 16 is in contact with the substation body 2. The opening and closing door 3 is located on the movement trajectory of the sealing plate 2 16, and the sealing plate 2 16 is used to seal the ventilation opening of the opening and closing door 3. The inclined block 19 is located on the movement trajectory of the sealing plate 2 16, and the inclined block 19 is used to provide a fixed limit for the sealing plate 2 16. When the device is in use, as the slider 9 moves, it synchronously drives the L-connector 15 to move, which in turn drives the sealing plate 16 to move. After moving a certain distance, the sealing plate 16 comes into contact with the ventilation opening of the sealing plate 13. After contacting the sealing plate 13, the sealing plate 16 moves further, completely sealing the opening of the sealing plate 13. Simultaneously, during its movement, the sealing plate... The second sealing plate 16 will contact the inclined surface of the inclined block 19. At this time, the second sealing plate 16 can squeeze and push the inclined block 19 to move through the inclined surface of the inclined block 19. After the inclined block 19 moves a certain distance, the inclined block 19 can press the second sealing plate 16 tightly on the surface of the opening and closing door 3 through the reset characteristic of the elastic telescopic rod 18. This can ensure the sealing effect of the second sealing plate 16 on the opening of the first sealing plate 13, and at the same time reduce the gap between the second sealing plate 16 and the first sealing plate 13, preventing rainwater from entering the equipment through the gap, and improving the water immersion sealing effect and quality of the device. Overall working principle: The movement of the elastic telescopic rod 12 will drive the sealing plate 13 to move. After moving a certain distance, the sealing plate 13 will contact the ventilation plate 14 and close the ventilation and heat dissipation vents of the ventilation plate 14. At the same time, the sealing plate 13 can waterproofly seal the opening of the ventilation plate 14, effectively preventing water from entering the bottom of the device and improving the water-proof sealing effect of the device. The inclined block 19 can press the sealing plate 16 tightly against the surface of the opening and closing door 3 through the reset characteristic of the elastic telescopic rod 18, ensuring the sealing effect of the sealing plate 16 on the opening of the sealing plate 13, and reducing the gap between the sealing plate 16 and the sealing plate 13, preventing rainwater from entering the equipment through the gap, thus improving the water-proof sealing effect and quality of the device.

[0021] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the sealing mechanism 4 includes an electric telescopic rod 401, which is fixedly connected to the inner wall of the base 1. The telescopic end of the electric telescopic rod 401 is fixedly connected to a fixing plate 402. The inner wall of the fixing plate 402 is fixedly connected to a sealing cover 403. The inner wall of the sealing cover 403 is fixedly connected to a sealing strip 404. The inner wall of the sealing cover 403 is fixedly connected to a water pump 405. The inner wall of the base 1 is fixedly connected to a filter plate 406. When the device is in use, the electric telescopic rod 401 will be activated. The telescopic end of the electric telescopic rod 401 will drive the fixed plate 402 to move. The movement of the fixed plate 402 will drive the sealing cover 403 to move. During the movement of the sealing cover 403, the sealing cover 403 will drive the sealing strip 404 to move synchronously. The movement of the sealing cover 403 will drive the water pump 405 to move. After the sealing cover 403 has moved a certain distance, it can seal the opening of the substation body 2 from the bottom, achieving a multi-layer sealing effect. At the same time, after the sealing cover 403 has completed its movement, the water pump 405 can be activated. The water pump 405 can drain the rainwater in the ventilation area to the outside through the connected one-way drainage pipe, achieving multi-layer sealing and preventing rainwater from entering the equipment.

The sealing cover 403 is in contact with the base 1. A spring is installed between the sealing column 408 and the fixed frame 407. The opening and closing door 3 is located on the movement trajectory of the sealing column 408, and the sealing column 408 is used to seal the opening and closing door 3. The T-block 409 is located on the movement trajectory of the pressure plate 411, and the pressure plate 411 is used to squeeze and push the T-block 409 to move. When the device is in use, the movement of the inclined block 19 will synchronously drive the fixed rod 410 to move. The movement of the fixed rod 410 will drive the pressure plate 411 to move. After moving a certain distance, the pressure plate 411 will contact the T block 409 and squeeze and push the T block 409 to move. The movement of the T block 409 will drive the sealing column 408 to move. After moving a certain distance, the sealing column 408 can seal the ventilation opening area of ​​the opening and closing door 3, preventing rainwater from entering the equipment through the side ventilation area of ​​the device, thereby affecting the normal use of the device. This can improve the all-round water immersion sealing effect of the device and extend the service life of the device. The clamping mechanism 5 includes a fixing block 501, which is fixedly connected to the inner wall of the sealing strip 404. A connecting post 502 is fixedly connected to the inner wall of the fixing block 501, and a scraper plate 503 is fixedly connected to the circumferential surface of the connecting post 502. During the use of this device, as the sealing strip 404 moves, the movement of the sealing strip 404 will cause the fixing block 501 to move, which in turn will cause the connecting column 502 to move. The movement of the connecting column 502 will simultaneously cause the scraper plate 503 to move. After moving a certain distance, the scraper plate 503 will come into contact with the filter plate 406. At this time, the scraper plate 503 can push and scrape away the debris that has settled on the surface of the filter plate 406 due to rainwater, which can effectively prevent the debris from affecting the subsequent sealing effect and avoid gaps in the sealing strip 404 due to the presence of debris, thereby affecting the sealing and water-proof effect of the device.

The sealing strip 404 is located on the movement trajectory of the guide rod 506. When the device is in use, after the sealing strip 404 moves a certain distance, it can contact the inclined surface of the guide rod 506. The sealing strip 404 can continue to move and squeeze the elastic telescopic rod 505 through the inclined surface of the guide rod 506. The elastic telescopic rod 505 can then perform telescopic movement. The telescopic movement of the elastic telescopic rod 505 can drive the guide rod 506 to move. When the sealing strip 404 reaches the plane of the guide rod 506, the guide rod 506 can apply pressure to the sealing strip 404 with the help of the reset characteristic of the elastic telescopic rod 505. This can improve the sealing effect of the sealing strip 404 and reduce the existence of sealing gaps. Overall working principle: The water pump 405 can drain rainwater from the ventilation area through the connected one-way drain pipe, achieving multi-layer sealing. This prevents rainwater from entering the equipment and from entering through the side ventilation area, thus affecting the normal operation of the device. It also improves the all-round water-proof sealing effect and extends the service life of the device. The scraper plate 503 can push and scrape away debris that has accumulated on the surface of the filter plate 406 due to rainwater, effectively preventing debris from affecting the subsequent sealing effect. This avoids gaps in the sealing strip 404 caused by debris, which would affect the water-proof sealing effect of the device. When the sealing strip 404 reaches the plane of the guide rod 506, the guide rod 506 can apply pressure to the sealing strip 404 with the reset characteristic of the elastic telescopic rod 505, which can improve the sealing effect of the sealing strip 404 and reduce the existence of sealing gaps.
