Description

Technical Field

[0001] The utility model relates to the field of waterproofing of distribution boxes, in particular to a waterproof structure of distribution boxes. Background Art

[0002] The distribution box is the final equipment of the power distribution system. The distribution box is a low-voltage distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to the electrical wiring requirements.

[0003] When the existing distribution box is in use, a large amount of heat is generated inside. Currently, one of the commonly used methods is to open a heat dissipation port on the surface of the distribution box and use a heat dissipation fan to blow the heat outward. The second method is to install heat dissipation fins on the side of the distribution box to use the heat dissipation fins to export the heat inside the distribution box. However, if the heat dissipation fins are used, the heat dissipation effect is far less than that of the heat dissipation fan. If a heat dissipation port is opened and a heat dissipation fan is used to blow the heat outward, the heat dissipation port is usually directly exposed to the outside without any waterproof and dustproof structure. External water and dust can easily enter the distribution box through the heat dissipation port. At the same time, once water enters the distribution box, it is easy to damage the lines and other equipment in the distribution box.

[0004] Therefore, it is necessary to invent a waterproof structure of a distribution box. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waterproof structure of a distribution box, comprising a distribution box and a protective cover, the protective cover being installed on the outside of the distribution box, cooling fans being installed on the upper ends of both sides of the distribution box, an empty groove being provided between the outer wall of the distribution box and the inner wall of the protective cover, a drain pipe being installed on the lower end of the empty groove, heat dissipation ports being symmetrically provided on the lower ends of both sides of the protective cover, a filter assembly being installed inside the heat dissipation port, and fixing components being provided at both ends of the heat dissipation port and the filter assembly.

[0007] Based on the above features: the protective cover can provide preliminary protection on the outside of the distribution box, and the set cooling fan can conduct the heat inside the distribution box to the outside. At this time, the heat can circulate inside the empty slot and be discharged outward through the heat dissipation port. The filter component is installed inside the heat dissipation port and fixed by a fixing component. The air passing through the heat dissipation port can be filtered to prevent external dust and water from entering the distribution box. If the filter component is damaged or broken, causing external water to enter the protective cover through the heat dissipation port, since the height of the cooling fan is higher than the heat dissipation port, the water will be located at the lower end of the inner cavity of the empty slot and will be led outward through the drain pipe. It will not enter the distribution box through the position of the cooling fan, further improving the waterproof effect.

[0008] Preferably, a groove is provided on the surface of the protective outer cover, the fixing assembly is located inside the groove, and a through hole is provided between the groove and the heat dissipation port.

[0009] Based on the above features: one end of the convenient fixing component passes through the through hole to clamp and limit the filter component.

[0010] Preferably, a drainage hole is provided at the bottom of the empty slot, and the drainage pipe is detachably connected to the drainage hole.

[0011] Based on the above characteristics: the accumulated water can fall into the drain pipe through the drain hole and be discharged.

[0012] Preferably, the filter assembly comprises an outer frame and a waterproof breathable membrane and a filter net arranged inside the outer frame, and resilient members are installed at four corners of one end of the outer frame.

[0013] Based on the above characteristics: the waterproof and breathable membrane can block water, and the filter can filter external dust to prevent water and dust from entering the protective cover and the distribution box.

[0014] Preferably, both ends of the outer frame are symmetrically provided with card slots.

[0015] Based on the above features: the fixing component can be inserted into the card slot to fix the outer frame to prevent the outer frame from being separated from the heat dissipation port.

[0016] Preferably, the resilient member comprises an outer tube and a movable rod movably connected to one end of the outer tube away from the outer frame, a piston plate is installed at one end of the movable rod, a compression spring is arranged at the other end of the piston plate, and the piston plate and the compression spring are located inside the outer tube.

[0017] Based on the above characteristics: when the outer frame is installed inside the heat dissipation port, the end of the movable rod away from the piston plate will first press against the outer wall of the distribution box. At this time, the movable rod will move toward the inside of the outer tube and use the piston plate to squeeze the compression spring to deform. When the outer frame is fixed by the fixing assembly, the compression spring will not be able to rebound the movable rod. When the outer frame needs to be removed, the fixing assembly is pulled open first. At this time, the compression spring will rebound the piston plate and the movable rod, and the movable rod will push the outer tube and the outer frame outward, so that the outer frame can automatically detach from the heat dissipation port.

[0018] Preferably, the fixing assembly includes a pull plate and a clamping block and a buffer spring symmetrically installed at two ends of one side of the pull plate, the buffer spring is located inside the groove, and the clamping block movably passes through the through hole.

[0019] Based on the above features: when the pull plate is pulled toward the end away from the heat dissipation port, the buffer spring will be squeezed and deformed, and the card block will retract into the inside of the groove. When the outer frame is installed so that the card slot is aligned with the through hole, the pull plate can be released, and the buffer spring will rebound the card block, so that the card block is stuck into the card slot to clamp and fix the outer frame.

[0020] The beneficial effects of the utility model are:

[0021] 1. The distribution box can be protected to prevent water from entering the inside of the distribution box. The cooling fan can conduct the heat inside the distribution box to the outside. At this time, the heat can flow inside the empty slot and be discharged outward through the heat dissipation port. The outer frame is fixed inside the heat dissipation port. The waterproof and breathable membrane can block water. The filter can filter external dust to prevent water and dust from entering the protective outer cover and the distribution box. If the waterproof and breathable membrane is damaged and cannot block water in time, since the height of the cooling fan is higher than the heat dissipation port, the water will be located at the lower end of the inner cavity of the empty slot and will be led outward through the drain pipe. It will not enter the distribution box through the position of the cooling fan, further improving the waterproof effect.

[0022] 2. To avoid the filter component being unable to be disassembled and cleaned for a long time, which affects the air circulation, when the outer frame is installed inside the heat dissipation port, you can pull the pull plate to move it to the end away from the heat dissipation port. At this time, the buffer spring will be squeezed and deformed, and the block will also retract into the groove. When the outer frame is installed inside the heat dissipation port, the slots at both ends of the outer frame will be aligned with the through holes. At this time, you can loosen the pull plate to facilitate the buffer spring to rebound the block, so that the block is stuck in the slot to clamp the outer frame. When disassembly is required, you only need to pull the pull plate again to disengage the block from the slot. No bolts are required, which is simple and convenient.

[0023] 3. Convenient and quick disassembly. When the outer frame is installed inside the heat dissipation port, the end of the movable rod away from the piston plate will first press against the outer wall of the distribution box. At this time, the movable rod will move toward the inside of the outer tube and use the piston plate to squeeze the compression spring to deform. When the outer frame needs to be disassembled, once the block is disengaged from the slot, the compression spring will rebound the piston plate and the movable rod, and the movable rod will push the outer tube and the outer frame outward, so that the outer frame will automatically detach from the heat dissipation port.

[0031] The protective cover 2 can provide preliminary protection outside the distribution box 1, and the provided cooling fan 3 can conduct the heat inside the distribution box 1 to the outside. At this time, the heat can circulate inside the empty slot 4 and be discharged to the outside through the heat dissipation port 6. The filter component 7 is installed inside the heat dissipation port 6 and fixed by the fixing component 8. The air passing through the heat dissipation port 6 can be filtered to prevent external dust and water from entering the distribution box 1. If the filter component 7 is damaged or broken, causing external water to enter the protective cover 2 through the heat dissipation port 6, since the height of the cooling fan 3 is higher than the heat dissipation port 6, the water will be located at the lower end of the inner cavity of the empty slot 4 and will be led out through the drain pipe 5, and will not enter the distribution box 1 through the position of the cooling fan 3, further improving the waterproof effect.

[0032] Furthermore, a groove 21 is formed on the surface of the protective cover 2 , the fixing assembly 8 is located inside the groove 21 , and a through hole 22 is formed between the groove 21 and the heat dissipation port 6 .

[0033] The fixing component 8 can be movably adjusted inside the groove 21 , so that one end of the fixing component 8 can pass through the through hole 22 to clamp and limit the filter component 7 .

[0034] Furthermore, a drainage hole 41 is provided at the bottom of the empty slot 4, and the drainage pipe 5 is detachably connected to the drainage hole 41.

[0035] The accumulated water can fall into the drain pipe 5 through the drain hole 41 and be discharged. The drain pipe 5 and the drain hole 41 can be connected by threads, so that the drain pipe 5 can be movably disassembled and maintained.

[0036] Furthermore, the filter assembly 7 includes an outer frame 71 and a waterproof and breathable membrane 72 and a filter screen 73 arranged inside the outer frame 71 . Resilient members 74 are installed at four corners of one end of the outer frame 71 .

[0037] The outer frame 71 is fixed inside the heat dissipation port 6 , the waterproof and breathable membrane 72 is provided to block water, and the filter net 73 is provided to filter external dust to prevent water and dust from entering the protective outer cover 2 and the distribution box 1 .

[0038] Furthermore, two ends of the outer frame 71 are symmetrically provided with slots 711 .

[0039] The fixing component 8 can be inserted into the card slot 711 to fix the outer frame 71 to prevent the outer frame 71 from being separated from the heat dissipation port 6. When disassembly is required, it is only necessary to pull the fixing component 8 out of the card slot 711, which is simple and convenient.

[0040] Furthermore, the resilient member 74 includes an outer tube 741 and a movable rod 742 movably connected to one end of the outer tube 741 away from the outer frame 71, a piston plate 743 is installed at one end of the movable rod 742, and a compression spring 744 is provided at the other end of the piston plate 743, and the piston plate 743 and the compression spring 744 are located inside the outer tube 741.

[0041] The movable rod 742 can utilize the piston plate 743 to squeeze the compression spring 744 to adaptively extend and retract. When the outer frame 71 is installed inside the heat dissipation port 6, the end of the movable rod 742 away from the piston plate 743 will first press against the outer wall of the distribution box 1. At this time, the movable rod 742 will move toward the inside of the outer tube 741 and utilize the piston plate 743 to squeeze the compression spring 744 to deform. When the outer frame 71 is fixed by the fixing component 8, the compression spring 744 will not be able to rebound the movable rod 742. When the outer frame 71 needs to be removed, the fixing component 8 is pulled open first. At this time, the compression spring 744 will rebound the piston plate 743 and the movable rod 742, and the movable rod 742 will push the outer tube 741 and the outer frame 71 back outward, so that the outer frame 71 can automatically detach from the heat dissipation port 6.

[0042] Furthermore, the fixing assembly 8 includes a pull plate 81 and a clamping block 82 and a buffer spring 83 symmetrically installed at two ends of one side of the pull plate 81 . The buffer spring 83 is located inside the groove 21 , and the clamping block 82 movably passes through the through hole 22 .

[0043] Personnel can move the pull plate 81 outside the groove 21. When the pull plate 81 is pulled toward the end away from the heat dissipation port 6, the buffer spring 83 will be squeezed and deformed. At this time, the block 82 will retract into the inside of the groove 21. When the outer frame 71 is installed so that the slot 711 is aligned with the through hole 22, the pull plate 81 can be released. At this time, the buffer spring 83 will rebound the block 82, so that the block 82 is clamped into the inside of the slot 711 to clamp and fix the outer frame 71.

[0044] The use process of the utility model is as follows: when installing the filter assembly 7, first move the pull plate 81 to retract the block 82 into the inside of the groove 21, then insert the outer frame 71 with the waterproof breathable membrane 72 and the filter screen 73 installed inside into the heat dissipation port 6, at this time, the end of the movable rod 742 away from the piston plate 743 will first press against the outer wall of the distribution box 1, and use the piston plate 743 to squeeze the compression spring 744 to deform, when the card grooves 711 at both ends of the outer frame 71 are aligned with the through hole 22, the pull plate 81 can be released to slow down the movement of the filter assembly 71. The impact spring 83 will rebound the block 82, so that the block 82 is inserted into the slot 711 to clamp the outer frame 71. At this time, the filter component 7 can be dustproof and waterproof in the heat dissipation port 6. If the filter component 7 is damaged or broken, causing external water to enter the protective outer cover 2 through the heat dissipation port 6, since the height of the cooling fan 3 is higher than the heat dissipation port 6, the water will be located at the lower end of the inner cavity of the empty slot 4 and will be led out through the drain pipe 5, and will not enter the distribution box 1 through the position of the cooling fan 3.
