Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4As shown, the utility model provides a technical solution: a distribution box protection structure, including a distribution cabinet 1, a limited side plate 2 is fixedly connected to one side of the inner wall of the distribution cabinet 1, and a plurality of distributors 201 are simultaneously slidably connected to one side of the inner wall of the distribution cabinet 1 through the limited side plate 2, a plurality of movable connecting parts 202 are simultaneously fixedly connected to one side of the outer wall of the limited side plate 2, and a screw 203 is rotatably connected to the inner center of the movable connecting part 202, one of the movable connecting parts 202 is rotatably connected to the bottom center of the adjusting knob 204, and the center of the top surface of the adjusting knob 204 is fixedly connected to the outer wall of the bottom end of the screw 203, an airtight cabinet door 3 is rotatably connected to one side of the inner wall of the distribution cabinet 1, and a plurality of sun and rain shields 301 are simultaneously fixedly connected to one side of the outer wall of the airtight cabinet door 3, a plurality of wiring holes 302 are simultaneously opened on one side of the outer wall of the airtight cabinet door 3, and an auxiliary slide rail 303 is slidably connected to the inner side of the airtight cabinet door 3.

[0024] By turning the adjustment knob 204, the distributor 201 moves vertically along the outer wall of the limiting side plate 2 under the joint action of the screw 203 and the limiting side plate 2, so that the distributor 201 can adjust its height autonomously according to the needs of the user. By providing a sealing strip 304 between the airtight cabinet door 3 and the main body of the distribution cabinet 1, the airtight performance of the distribution cabinet 1 can be significantly improved. In addition, when the distribution cable passes through the wiring hole 302, the airtight rubber ring 305 is in close contact with the outer wall of the cable, further ensuring the airtightness inside the distribution cabinet 1 and preventing water vapor and other external factors. To prevent damage to the equipment, when using the wiring hole 302, the seal 306 can be removed from the wiring hole 302 to facilitate the installation and maintenance of the cable without hindering the normal wiring of the cable. When the wiring hole 302 is in an idle state, the seal 306 can be reinserted into the wiring hole 302 to further improve the airtightness of the distribution cabinet 1, effectively reduce the risk of external water vapor entering the interior of the distribution cabinet 1 through the wiring hole 302, and significantly improve the protection capability of the distribution cabinet 1 in outdoor environments, ensuring the stable operation of the power system and the long-term reliability of the equipment.

[0025] like Figure 1-2 As shown, the top outer wall of the limiting side plate 2 is simultaneously connected to one side of the bottom surface of multiple distributors 201, and the top of the outer wall of the limiting side plate 2 is simultaneously slidably connected to one side of the inside of multiple distributors 201, and the sliding trajectory of the distributor 201 inside the distribution cabinet 1 is limited by the limiting side plate 2.

[0026] The outer wall at the top end of the screw 203 is simultaneously connected to the center of the bottom surface of multiple distributors 201, and the top of the outer wall of the screw 203 is simultaneously connected to the internal center of multiple distributors 201 through a thread. The screw 203 cooperates with the limiting side plate 2 through the outer wall thread. When the screw 203 rotates, it can push multiple distributors 201 to move vertically along the limiting side plate 2 at the same time.

[0027] The top outer wall of the adjusting knob 204 is connected to the center of the bottom surface of one of the movable connecting parts 202, and the top center of the adjusting knob 204 passes through the inner center of the movable connecting part 202 and is fixedly connected to the bottom outer wall of the screw 203, so that the adjusting knob 204 can smoothly drive the screw 203 to rotate inside the distribution cabinet 1.

[0028] like Figure 1 、 Figure 3 and Figure 4 As shown, a sealing strip 304 is fixedly connected to the outer wall of one side of the distribution cabinet 1, and the sealing strip 304 fits tightly with the inner side of the airtight cabinet door 3, which can effectively improve the airtightness of the distribution cabinet 1 when the airtight cabinet door 3 is closed, and reduce the possibility of external rainwater and moisture penetrating into the interior of the distribution cabinet 1 along the door gap.

[0029] An airtight rubber ring 305 is provided on the inner wall of the wiring hole 302 so that when the distribution cable passes through the wiring hole 302 for routing, the airtight rubber ring 305 can contact the outer wall of the distribution cable to ensure the airtightness inside the distribution cabinet 1.

[0030] One side of the outer wall of the auxiliary slide rail 303 is connected to the outer wall of one side of the airtight cabinet door 3, and one side of the outer wall of the auxiliary slide rail 303 is slidably connected to the inside of the airtight cabinet door 3. The outer wall of one side of the auxiliary slide rail 303 is rotatably connected to a seal 306, and the seal 306 is located on the inside of the airtight cabinet door 3. When the wiring hole 302 is in use, the seal 306 can be taken out from the inside of the wiring hole 302 without hindering the routing of the distribution cables.

[0031] The outer wall of one side of the seal 306 is connected through the wiring hole 302 and the center of the airtight rubber ring 305, and one side of the outer wall of the seal 306 corresponds to the airtight rubber ring 305. When the wiring hole 302 is idle, the seal 306 can be inserted into the wiring hole 302 to further improve the airtightness inside the distribution cabinet 1 and effectively reduce the external water vapor from entering the distribution cabinet 1 through the wiring hole 302.

[0032] Working principle: The sliding track of the distributor 201 inside the distribution cabinet 1 is limited by the limiting side plate 2, and the screw 203 cooperates with the limiting side plate 2 through the outer wall thread. When the screw 203 rotates, it can push multiple distributors 201 to move vertically along the limiting side plate 2 at the same time, so that the adjustment knob 204 can smoothly drive the screw 203 to rotate inside the distribution cabinet 1, which can effectively improve the airtightness of the distribution cabinet 1 when the airtight cabinet door 3 is closed, reduce the possibility of external rainwater and moisture penetrating into the distribution cabinet 1 through the door gap, and make the distribution cabinet 1 more airtight. When the electric cables are routed through the wiring hole 302, the airtight rubber ring 305 can contact the outer wall of the distribution cable to ensure the airtightness inside the distribution cabinet 1. When the wiring hole 302 is in use, the seal 306 can be taken out from the wiring hole 302 without hindering the routing of the distribution cable. When the wiring hole 302 is idle, the seal 306 can be inserted into the wiring hole 302 to further improve the airtightness inside the distribution cabinet 1 and effectively reduce the external water vapor from entering the distribution cabinet 1 through the wiring hole 302.
