Its operational stability is directly related to the safety and reliability of power supply.

[0003] When summer arrives, the prolonged operation of power distribution cabinets leads to excessively high internal temperatures, making heat dissipation difficult and causing internal safety hazards. This also significantly impacts the working environment of large internal components and can even lead to fires. To address these issues, a power distribution cabinet for heat dissipation can be described in existing technology (Chinese patent application number CN201620362142.7, application date 2016-04-25).

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This highly secure distribution cabinet, through the cooperation of a protective shell, a waterproof frame, and a fitted air cushion, effectively prevents rainwater intrusion and reduces the risk of damage to electrical components; the lifting mechanism can adjust the height of the distribution cabinet body to adapt to special environments such as water accumulation, improving protection and safety; the cleaning mechanism is linked with the lifting mechanism, the cleaning brush cleans dust from the heat dissipation vents, and the air jet mechanism quickly expels dust, ensuring heat dissipation efficiency and extending the life of components; and the drive component synchronously drives the lifting and cleaning functions, saving energy consumption.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 The present invention provides the following technical solution: a power distribution cabinet with high security.

[0020] Example 1: To address the issue that current distribution cabinets on the market may experience water ingress during summer use due to unpredictable weather conditions, such as heavy rain, potentially damaging internal electrical components, please refer to the attached... Figure 1 - Appendix Figure 4 The protective housing 2 is equipped with a drive component, which drives the lifting assembly to operate. The lifting assembly acts on the bottom of the power distribution cabinet body 1 to adjust the height of the power distribution cabinet body 1 within the protective housing 2. A waterproof frame 101 with a top tilting front and back is installed on the top of the power distribution cabinet body 1. An air cushion 102 is attached to the bottom of the waterproof frame 101 to seal the waterproof frame 101 with the top of the protective housing 2. A discharge port 3 is opened at the bottom of the protective housing 2. The drive component includes a drive motor 4, the output end of which is connected to the bottom end of the rotating sleeve 5 included in the lifting mechanism. The lifting mechanism also includes a threaded rod 6 threaded to the inner side of the rotating sleeve 5. The top of the threaded rod 6 is fixed at the center position of the bottom of the power distribution cabinet body 1. In addition, the bottom position of the power distribution cabinet body 1 is also connected to the inner bottom end of the discharge port 3 through a guide component 7. Furthermore, the side wall of the power distribution cabinet body 1 is slidably disposed in a groove 8 opened inside the discharge port 3.

[0021] After the drive motor 4 in the drive unit starts, its output end drives the rotating sleeve 5 of the lifting mechanism to rotate. Since the rotating sleeve 5 is threadedly connected to the threaded rod 6, and the distribution cabinet body 1 is connected to the bottom end of the discharge port 3 through the guide 7 and the side wall slides along the slide groove 8, the threaded rod 6 will rotate with the rotating sleeve 5 to drive the distribution cabinet body 1 to make stable height adjustment within the protective shell 2. When it rains heavily, the distribution cabinet body 1 can be lowered so that more of it can be stored inside the protective shell 2. At the same time, the waterproof frame 101 with the front and rear tilting at the top, together with the fitting air cushion 102 below, can seal and close with the top of the protective shell 2, effectively preventing rainwater from entering. The discharge port 3 can promptly discharge any small amount of water that may seep into the protective shell 2. The multiple structures work together to prevent electrical components from being damaged by water, thus improving safety.

[0022] Example 2: To clean the heat dissipation vent 103 of the power distribution cabinet body 1, please refer to the attached document. Figure 1 and attached Figure 4 - Appendix Figure 6 The lifting assembly is also linked to a cleaning mechanism, which operates on the heat dissipation vent 103 on the power distribution cabinet body 1 to clean the deposits on the surface of the vent 103, thereby improving the heat dissipation efficiency of the power distribution cabinet body 1. The cleaning mechanism includes a fixed rack 9 fixed to the rear side of the inner wall of the power distribution cabinet body 1. A mating gear 10 is meshed with the outer side of the fixed rack 9. The center of the mating gear 10 is fixedly connected to a threaded screw 11. A cleaning brush 12 is threadedly connected to the outer side of the threaded screw 11, and the outer side of the cleaning brush 12 corresponds to the outer side of the heat dissipation vent 103. The cleaning mechanism is also connected to an air jet mechanism for quickly discharging the cleaned dust. The gear 10 is rotatably mounted on the rear side of the distribution cabinet body 1, and the gear 10 forms a rotating structure with the outer wall of the distribution cabinet body 1 through the fixed rack 9; the jet mechanism includes a movable piston rod 13 fixed on the outside of the cleaning brush 12, the outer end of the movable piston rod 13 is slidably mounted inside the fixed air cylinder 14, and the cleaning brush 12 has several sets of one-way exhaust nozzles 15 facing the heat dissipation port 103; a set of rubber rings is nested on the outer wall of the movable piston rod 13, and the outer side of the rubber rings is attached to the inner wall of the fixed air cylinder 14; a one-way air outlet is provided at the end of the movable piston rod 13, and a one-way air inlet valve is provided on one side of the fixed air cylinder 14.

[0023] When the lifting assembly drives the distribution cabinet body 1 to adjust its height, the fixed rack 9 on the rear side of the inner wall of the distribution cabinet body 1 moves synchronously with the body. Because the gear 10 meshes with the fixed rack 9 and is rotatably set on the rear side of the distribution cabinet body 1, the movement of the fixed rack 9 will drive the gear 10 to rotate, thereby driving the threaded screw 11 fixedly connected to it to rotate synchronously. Since the cleaning brush 12 is threadedly connected to the threaded screw 11, the rotation of the threaded screw 11 will cause the cleaning brush 12 to move along the screw axis, and its outer side corresponds to the heat dissipation port 103, thereby wiping and cleaning the deposits on the surface of the heat dissipation port. At the same time, when the cleaning brush 12 moves, it will drive the outer moving piston rod 13 to slide in the fixed air cylinder 14. The rubber ring on the outer wall of the moving piston rod 13 ensures the air cylinder's sealing. With the one-way air outlet at its end and the one-way air inlet valve of the fixed air cylinder 14, the gas in the air cylinder is sprayed out unidirectionally through the air nozzle 15 on the cleaning brush 12, quickly expelling the cleaned dust, avoiding blockage of the heat dissipation port, and ensuring stable heat dissipation efficiency.
