Specific implementation mode

[0029] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation modes.

[0030] Embodiment 1: Refer to Figures 1-4 , a wall-mounted waterproof distribution box, including a cabinet body 2, a cabinet door 1 is arranged on the cabinet body 2, and an inclined baffle 5 is arranged at the top of the cabinet body 2. Two mounting plates 4 are welded on the back of the cabinet body 2, and mounting holes are opened on the mounting plates 4. A rain sensor 6 is arranged at the top of the inclined baffle 5. Ventilation openings 20 are arranged on both outer walls of the cabinet body 2. Dust removal nets 18 are fixedly connected inside the ventilation openings 20. A transmission cavity 21 is arranged on one side of each ventilation opening 20. A rotating shaft 23 is rotatably connected at the connection between the transmission cavity 21 and the ventilation opening 20, and one end of the rotating shaft 23 is rotatably connected to the inner wall of the ventilation opening 20. Louver boards 3 are fixedly connected to the outer wall on one side of the rotating shaft 23, and a plurality of louver boards 3 can seal the ventilation opening 20. The other ends of the rotating shafts 23 are fixedly connected with worm gears 22, and the same driving mechanism is arranged on the outer walls of a plurality of worm gears 22. Water storage tanks 12 are arranged on both sides of the top of the cabinet body 2, and a telescopic mechanism is arranged between the two water storage tanks 12. Filter screens 11 are arranged on the tops of the water storage tanks 12. When the rain sensor 6 senses that the rain is heavy, the two water storage tanks 12 are separated from each other through the telescopic mechanism, so that the water storage tanks 12 extend out of the inclined baffle 5, and rainwater can enter the water storage tanks 12 along the inclined baffle 5. The filter screens 11 can filter impurities and garbage. During the extension process of the water storage tanks 12, each rotating shaft 23 can be rotated through the driving mechanism, so that the louver boards 3 in the ventilation openings 20 swing, and the louver boards 3 are closely attached to each other, so as to seal the ventilation openings 20 and prevent external rainwater from entering the cabinet body 2 through the ventilation openings 20.

[0031] As a further solution in the present invention, cooling pipes 19 are fixedly connected to the inner walls on both sides of the cabinet body 2, and both the top and bottom ends of the cooling pipes 19 penetrate through the cabinet body 2 and extend to the outside of the cabinet body 2. A telescopic pipe 13 is fixedly connected to the top end of the cooling pipe 19, and the telescopic pipe 13 is connected to the corresponding water storage tank 12. The rainwater entering the water storage tank 12 will enter the cooling pipe 19 along the telescopic pipe 13, and finally the rainwater flows along the cooling pipe 19. During this process, the rainwater can absorb the heat generated by the operation of each electronic component in the cabinet body 2. Finally, the rainwater that has absorbed the heat is discharged to the outside through the bottom end of the cooling pipe 19, avoiding the situation where heat dissipation cannot be achieved due to the closing of the ventilation opening 20, ensuring that when the ventilation opening 20 is closed during rain, the cabinet body 2 still has good heat dissipation function.

[0032] As a further solution in the present invention, the telescopic mechanism includes two fixing plates one 14, the two fixing plates one 14 are fixedly connected to the outer wall of the top of the cabinet body 2, and a bidirectional threaded rod 9 is rotatably connected between the two fixing plates one 14. A rotary motor 7 is arranged at one end of the bidirectional threaded rod 9, and threaded sliders 8 are threadedly slidably connected to the outer walls on both sides of the bidirectional threaded rod 9. The rotary motor 7 rotates the bidirectional threaded rod 9, causing the two threaded sliders 8 on the outer wall of the bidirectional threaded rod 9 to approach each other.

[0033] As a further solution in the present invention, connecting plates 10 are hinged to the outer walls on both sides of the threaded slider 8, and one ends of the two connecting plates 10 on the same side are hinged to the outer wall of the corresponding water storage tank 12. A plurality of balls are arranged at the bottom of the connecting plates 10, and the balls are in contact with the top of the cabinet body 2. The connecting plates 10 can move the water storage tank 12 away from the cabinet body 2, causing the water storage tank 12 to extend out from under the inclined baffle 5, and the balls can support the connecting plates 10 and disperse the force they receive, improving their stability.

[0034] As a further solution in the present invention, the driving mechanism includes a worm 17, the worm 17 is rotatably connected inside the transmission cavity 21, and the worm 17 meshes with a plurality of worm wheels 22. A gear 16 is fixedly connected to the top end of the worm 17, and a rack 15 is externally meshed with the gear 16. The rack 15 is fixedly connected to the outer wall of the corresponding water storage tank 12. During the process of the water storage tank 12 extending out from under the inclined baffle 5, it will drive the rack 15 to move. Since the rack 15 meshes with the gear 16 at the top end of the worm 17, the worm 17 can be rotated, and the worm 17 meshes with a plurality of worm wheels 22, so that a plurality of rotating shafts 23 rotate synchronously.

[0035] Working principle: When the rain sensor 6 senses a heavy rain, the rotary motor 7 rotates the bidirectional threaded rod 9, causing the two threaded sliders 8 on the outer wall of the bidirectional threaded rod 9 to approach each other. Through the connecting plate 10, the water storage tank 12 can be moved away from the cabinet body 2, so that the water storage tank 12 extends out from below the inclined baffle 5. And the ball can support the connecting plate 10, disperse the force it receives, and improve its stability. When the water storage tank 12 extends out, the rainwater can enter the water storage tank 12 along the inclined baffle 5. The filter screen 11 can filter out impurities and garbage. And when the water storage tank 12 extends out, it will drive the rack 15 to move. Since the rack 15 meshes with the gear 16 at the top of the worm 17, the worm 17 can be rotated. And the worm 17 meshes with multiple worm wheels 22, causing multiple rotating shafts 23 to rotate synchronously. Thus, each louver 3 in the ventilation opening 20 swings, and each louver 3 is closely attached together, which can seal the ventilation opening 20 and prevent the outside rainwater from entering the cabinet body 2 through the ventilation opening 20. And the rainwater entering the water storage tank 12 will flow into the cooling pipeline 19 along the telescopic pipe 13. Finally, the rainwater flows along the cooling pipeline 19. And in this process, the rainwater can absorb the heat generated when each electronic component in the cabinet body 2 operates. Finally, the rainwater that has absorbed the heat is discharged to the outside through the bottom end of the cooling pipeline 19, avoiding the situation that the ventilation opening 20 is closed and cannot dissipate heat, and ensuring that when it rains and the ventilation opening 20 is closed, the cabinet body 2 still has a good heat dissipation function.

[0036] Embodiment 2: Refer to Figures 1-7 , a wall-mounted waterproof distribution box. Compared with Embodiment 1, on the basis of Embodiment 1, sliding grooves 28 are respectively opened on the outer walls above both sides of the water storage tank 12, and L-shaped sliders 29 are respectively slidably connected inside the sliding grooves 28. The tops of the two L-shaped sliders 29 are fixedly connected with a cleaning brush 26, and a pulling rope 24 is fixedly connected to the outer wall of the cleaning brush 26 facing the cabinet body 2. One end of the pulling rope 24 is fixedly connected with a second fixing plate 25, and the second fixing plate 25 is fixedly connected to the bottom outer wall of the inclined baffle 5. When the telescopic mechanism makes the two water storage tanks 12 move away from each other and extend out of the inclined baffle 5, through the pulling of the pulling rope 24, the cleaning brush 26 can be moved on the top of the water storage tank 12, so that the cleaning brush 26 can clean the filter screen 11 and remove the garbage and impurities existing on the filter screen 11, avoiding the blockage of the filter screen 11 and affecting the water storage efficiency.

[0037] As a further solution in the present invention, a third fixing plate 30 is provided on one side of the L-shaped slider 29, and the third fixing plate 30 is fixedly connected to the outer wall of the water storage tank 12. A first connecting spring 27 is fixedly connected between the third fixing plate 30 and the L-shaped slider 29. When the water storage tank 12 extends out the inclined baffle 5 and causes the cleaning brush 26 to move, the first connecting spring 27 between the L-shaped slider 29 and the third fixing plate 30 will be compressed. Thus, when the water storage tank 12 resets, under the elastic force of the first connecting spring 27, the cleaning brush 26 can be reset, so that the cleaning brush 26 can clean the filter net 11 for the second time, preventing garbage and impurities from remaining on the filter net 11.

[0038] Working principle: When the telescopic mechanism moves the two water storage tanks 12 away from each other and extends out the inclined baffle 5, by pulling the pulling rope 24, the cleaning brush 26 can be moved on the top of the water storage tank 12, so that the cleaning brush 26 can clean the filter net 11, removing the garbage and impurities on the filter net 11 and preventing the filter net 11 from being blocked and affecting the water storage efficiency; when the water storage tank 12 extends out the inclined baffle 5 and causes the cleaning brush 26 to move, the first connecting spring 27 between the L-shaped slider 29 and the third fixing plate 30 will be compressed. Thus, when the water storage tank 12 resets, under the elastic force of the first connecting spring 27, the cleaning brush 26 can be reset, so that the cleaning brush 26 can clean the filter net 11 for the second time, preventing garbage and impurities from remaining on the filter net 11.

[0039] Embodiment 3: Refer to Figures 1-8 , a wall-mounted waterproof distribution box. Compared with Embodiment 2, on the basis of Embodiment 2, accommodation cavities 32 are provided above the ventilation openings 20, and a sealing baffle 31 is slidably connected to the connection between the accommodation cavity 32 and the ventilation opening 20. The sealing baffle 31 is hermetically slidably connected to the inner wall of the ventilation opening 20, and the bottom cross-section of the sealing baffle 31 is semi-circular. A limiting plate 34 is fixedly connected to the top of the sealing baffle 31, and a second connecting spring 33 is fixedly connected between the limiting plate 34 and the accommodation cavity 32. Under the elastic force of the second connecting spring 33, the sealing baffle 31 will be pressed downward, so that the bottom end of the sealing baffle 31 always closely adheres to the surface of the uppermost louver 3. Since the sealing baffle 31 is hermetically slidably connected to the inner wall of the ventilation opening 20, no matter how the uppermost louver 3 swings, the sealing baffle 31 can seal the gap between the uppermost louver 3 and the ventilation opening 20, preventing water vapor from entering the cabinet body 2 due to the existence of the gap.

[0040] Working principle: Under the elastic force of the connecting spring two 33, the sealing baffle 31 will be pressed downward, so that the bottom end of the sealing baffle 31 always closely adheres to the surface of the uppermost louver 3. Since the sealing baffle 31 is in sealed sliding connection with the inner wall of the ventilation opening 20, no matter how the uppermost louver 3 swings, the sealing baffle 31 can seal the gap between the uppermost louver 3 and the ventilation opening 20, avoiding the entry of water vapor into the cabinet body 2 due to the existence of the gap.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
