Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, in particular to a dustproof device for electrical equipment. Background Art

[0002] An electrical cabinet is a cabinet used to protect and centrally install electrical components. A variety of circuit control and detection components are centrally installed inside the electrical cabinet, which will generate a certain amount of heat during use. If the heat cannot be discharged from the electrical cabinet in time, the temperature of the electrical cabinet will rise, affecting the service life of the electrical cabinet. However, while dissipating heat, due to the large amount of dust in the air, the dust will enter the interior of the electrical cabinet through the heat dissipation port, causing a large amount of dust to adhere to the electrical components. This dust will accelerate the corrosion and damage of the components inside the electrical cabinet, thereby reducing its service life.

[0003] A Chinese patent document (application publication number CN212115925U) discloses a dustproof electrical cabinet, which includes a cabinet body, a heat dissipation structure and a control structure. One side of the cabinet body is rotatably connected to the cabinet door through a rotating plate, and a door lock is detachably connected to the outer surface of the cabinet door. One side of the cabinet body is fixedly connected to the heat dissipation structure and the control structure through screws. The heat dissipation structure is located below the control structure, and the top of the heat dissipation mechanism is electrically connected to the control structure through a wire. The inner surface of the cabinet body is glued to the heat dissipation pipe by glue.

[0004] It can be seen that the patent document cited above prevents dust from entering the interior of the electrical cabinet by setting up filters, but these filters are fixed and inconvenient to disassemble and clean. After long-term filtration, a large amount of dust will adhere to the surface of the filter, thereby affecting the heat dissipation effect of the electrical cabinet. Utility Model Content

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The dustproof device for electrical equipment benefits from the design of the turning knob, the screw rod, the connecting plate and the dustproof mechanism. The turning knob drives the connecting block to move upward through the screw rod, and the connecting block drives the dustproof mechanism to move upward through the connecting plate until the connecting block contacts the top of the placement cavity. At this time, the dustproof mechanism is located outside the dustproof box. The dustproof mechanism is pulled to one side to separate it from the connecting plate. In this way, it is convenient to disassemble and clean the dustproof mechanism, and a large amount of dust is prevented from being attached to its surface after long-term filtration, thereby not affecting the heat dissipation effect of the electrical cabinet.

At the same time, the two sets of dust-proof mechanisms can be disassembled and cleaned separately, so that the dust-proof mechanisms can be disassembled and cleaned alternately to prevent dust from entering the interior of the electrical cabinet during the disassembly process.

The top ends of the two screw rods 6 pass through the dustproof box 2. The screw rod 6 is connected to the bearing at the top end of the dustproof box 2, and a twist knob 7 is installed on the top end of the screw rod 6. The outer wall of the twist knob 7 is provided with an anti-slip thread to increase the friction between the human hand and the outer wall of the twist knob 7, which is convenient for rotating the twist knob 7. Rotating the twist knob 7 drives the screw rod 6 to rotate, and then drives the connecting plate 3 to move upward through the connecting block 5, until the dustproof mechanism 4 moves upward out of the dustproof box 2, and then separates it from the connecting plate 3. This method is convenient for disassembly and cleaning of the dustproof mechanism 4, and avoids a large amount of dust adhering to its surface after long-term filtration, thereby affecting the heat dissipation effect of the electrical cabinet.

[0027] The dustproof mechanism 4 provided in this embodiment is composed of a fixed frame 401 and a dustproof net 402. The inner wall of the fixed frame 401 is installed with a dustproof net 402. By arranging two groups of dustproof mechanisms 4 in the dustproof box 2, dust can be filtered multiple times, thereby improving the dustproof effect of the dustproof box 2 and making the air entering the electrical cabinet cleaner.

[0028] The present embodiment provides that the bottom ends of the screw rod 6 are respectively connected to the bearings on both sides of the bottom end of the placement cavity 201, and the two sides of the two connecting plates 3 are installed with guide sliders 9 for guiding and limiting the movement of the connecting plates 3. The guide sliders 9 are rectangular in shape but not limited to rectangles, and can also be other shapes, which can play a guiding and limiting role for the connecting plates 3. Guide grooves adapted to the guide sliders 9 are provided on both sides of the placement cavity 201, and the guide sliders 9 are slidably connected to the guide grooves. The bottom ends of the two fixed frames 401 are installed with connecting sliders 8 for connecting and fixing the fixed frames 401.

[0030] How it works

[0031] The electrical cabinet uses the dustproof box 2 to dissipate heat and prevent dust. After the electrical cabinet dissipates heat for a period of time, first rotate the knob 7 connected to the dustproof mechanism 4 on one side of the cabinet body 1. The rotation of the knob 7 drives the screw rod 6 to rotate. The rotation of the screw rod 6 drives the connecting block 5 to move upward, and then drives the dustproof mechanism 4 to move upward through the connecting plate 3 until the connecting block 5 contacts the top of the placement cavity 201. At this time, the dustproof mechanism 4 moves upward out of the dustproof box 2, and then the fixing frame 401 is pulled out to one side to separate the fixing frame 401 from the connecting plate 3. In this way, it is convenient to disassemble and clean the dustproof mechanism 4 to avoid a large amount of dust adhering to its surface after long-term filtration, thereby not affecting the heat dissipation effect of the electrical cabinet. After the dustproof mechanism 4 is cleaned and installed, the other dustproof mechanism 4 is disassembled and cleaned in the same way. By setting two sets of dustproof mechanisms 4, dust can be filtered multiple times, the dustproof effect of the dustproof box 2 is improved, and the air entering the electrical cabinet is cleaner. At the same time, the two sets of dustproof mechanisms 4 can be disassembled and cleaned separately, so that the dustproof mechanisms 4 can be disassembled and cleaned alternately to prevent dust from entering the interior of the electrical cabinet.
