The emergence of transformer cabinets is to meet this demand and provide a safe and reliable working environment for transformers. It adopts a closed design, which can effectively prevent the intrusion of dust, moisture, corrosion and other pollutants to ensure the normal operation of the transformer.

[0003] The patent with announcement number CN218788310U currently discloses a dustproof transformer cabinet, including a cabinet body, an inner layer fixedly installed at both ends of the inner wall of the cabinet body, and the inner wall of the inner layer is hollow, and a clamping mechanism. The clamping mechanism includes a spring one end fixedly installed on the top of the inner wall of the inner layer, and the other end extending downward, a hexagonal plug rod fixedly connected to the extended end of the spring, a guide wheel fixedly installed on the bottom of the inner wall of the inner layer, one end of the steel wire rope fixedly connected to the top of the hexagonal plug rod, and the other end slides on the outer wall of the guide wheel to extend outward, a pull block fixedly connected to the extended end of the steel wire rope, a spring is connected to the top of the inner layer, a hexagonal plug rod is connected to the bottom of the spring, a steel wire rope is connected to the hexagonal plug rod, and a pull block is connected to the end of the steel wire rope. The hexagonal plug rod is raised by pulling the steel wire rope, so that the dust filter can be quickly pulled out to clean the dust on the surface of the dust filter.

[0004] However, the above technology still has the following problems:

[0005] There are vents and line inlets on the surface of the transformer cabinet, and the size of the line inlet is larger than the cross-section of the cable. After the cable is connected, there will be a large gap between the cable and the line inlet.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figures 1 to 8 A dustproof transformer cabinet comprises a cabinet body 1, wherein the cabinet body 1 is provided with a ventilating port and a line inlet, a ventilation hood 2 is fixedly connected to the surface of the cabinet body 1, a dustproof net 3 is fixedly connected to the ventilating port, two sliding rods 4 are fixedly connected to the inner wall of the ventilation hood 2, a cleaning mechanism 5 is slidably connected to the sliding rod 4, a sealing mechanism 6 is provided on the outer surface of the line inlet, and the cleaning mechanism 5 is detachably connected to the sliding rod 4.

[0026] The dustproof transformer cabinet in the utility model is similar to the existing transformer cabinet structure. For example, the patent with announcement number CN218788310U discloses a dustproof transformer cabinet. The main improvement of the utility model is that the dustproof net 3 is used to prevent dust from entering the interior of the transformer cabinet through the vents. At the same time, the dust attached to the surface of the dustproof net 3 is cleaned under the action of the cleaning mechanism 5 to ensure the dustproof effect of the dustproof net 3. Under the action of the sealing mechanism 6, the gap between the cable and the line inlet is blocked and sealed to prevent dust from entering the interior of the transformer cabinet from the gap. At the same time, the sealing mechanism 6 can also fix the cable and prevent the cable from being damaged by friction with the line inlet. Figures 1 to 8 As shown, in the dustproof transformer cabinet of the present invention, when connecting the cable to the cabinet body 1, the nut 604 is first sleeved on the cable, the front end of the cable is inserted into the line inlet and connected to the cabinet body 1, and then the two prepared semicircular rubber blocks 602 are sleeved on the surface of the cable, and the rubber blocks 602 are pushed into the threaded tube 601, and then the nut 604 is threadedly connected with the threaded tube 601, and the rubber block 602 is placed between the nut 604 and the threaded tube 601, so that the rubber block 602 is not easy to slide off, thereby blocking the gap between the cable and the line inlet, and the dustproof net 3 can prevent dust from entering the cabinet from the vent. 1, when installing the cleaning mechanism 5, the limit block 505 is pressed to move inward along the sliding cavity 503, the spring 504 is compressed, and the movable base 501 is placed in the sliding groove 502, and the limit block 505 is released. Under the action of the spring 504, the limit block 505 moves outward. At this time, the upper end of the limit block 505 just fits the upper end of the sliding rod 4, and the cleaning mechanism 5 can be slidably connected with the sliding rod 4. The cleaning mechanism 5 can be removed by the opposite operation. By moving the cleaning mechanism 5 left and right, the soft brush 506 can sweep off the dust attached to the dustproof net 3, thereby ensuring the dustproof effect of the dustproof net 3.

[0027] like Figure 2 As shown, the plane formed by the two sliding rods 4 is parallel to the inner wall of the ventilation hood 2.

[0028] Specifically, the plane formed by the slide rods 4 is parallel to the inner wall of the ventilation cover 2 , which facilitates the cleaning mechanism 5 to be slidably connected to the slide rods 4 .

[0029] like Figure 3 , Figure 4 , Figure 5 or Figure 8As shown, the front end of the cleaning mechanism 5 is flush with the ventilation hood, and the cleaning mechanism 5 includes a base 501 slidably connected to the sliding rod 4, the upper surface of the base 501 is provided with a sliding groove 502, the interior of the base 501 is provided with a sliding cavity 503, the inner wall of the sliding cavity 503 is fixedly connected with a spring 504, the output end of the spring 504 is fixedly connected with a limiting block 505, and the side of the base 501 is fixedly connected with a soft brush 506.

[0030] Specifically, when installing the cleaning mechanism 5, the limit block 505 is pressed and moved inward along the sliding cavity 503, the spring 504 is compressed, and the movable base 501 is placed in the sliding groove 502. When the limit block 505 is released, the limit block 505 moves outward under the action of the spring 504. At this time, the upper end of the limit block 505 just fits the upper end of the sliding rod 4, and the cleaning mechanism 5 can be slidably connected to the sliding rod 4. The cleaning mechanism 5 can be removed by following the opposite operation. By moving the cleaning mechanism 5 left and right, the soft brush 506 can sweep off the dust attached to the dustproof net 3, thereby ensuring the dustproof effect of the dustproof net 3.

[0031] like Figure 3 As shown, the depth of the slide groove 502 in the vertical direction is the same as the distance from the lower surface of the slide rod 4 to the inner wall of the ventilation hood 2 in the vertical direction.

[0032] Specifically, the slide rod 4 can enter the slide groove 502 of the cleaning mechanism 5 at the same time. At this time, the limit block 505 is released, so that the cleaning mechanism 5 and the slide rod 4 can be slidably connected.

[0033] like Figure 1 or Figure 6 As shown, the sealing mechanism 6 includes a threaded tube 601 fixed on the surface of the wire inlet of the cabinet 1, a rubber block 602 is arranged in the threaded tube 601, a circular groove 603 is opened on the surface of the rubber block 602, a nut 604 is threadedly connected to the threaded tube 601, and a circular hole 605 is opened on the surface of the nut 604.

[0034] Specifically, the nut 604 is first put on the cable line, and the front end of the cable line is inserted into the cable inlet and connected to the cabinet 1. Then the two prepared semicircular rubber blocks 602 are put on the surface of the cable line, and the rubber blocks 602 are pushed into the threaded tube 601. Then the nut 604 and the threaded tube 601 are threadedly connected. The rubber block 602 is placed between the nut 604 and the threaded tube 601, so that the rubber block 602 is not easy to slip, thereby blocking the gap between the cable line and the cable inlet, and preventing dust in the environment from entering the cabinet 1.

[0035] like Figure 7 As shown, the cross section of the circular groove 603 is the same as that of the cable, and the cross section of the circular hole 605 is the same as that of the cable inlet.

[0036] Specifically, the same cross-section enables the cable and the threaded tube 601 to fit tightly together without any gaps, thereby effectively preventing dust from entering the cabinet 1 .

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
