DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4 , including a distribution cabinet body 1 and a vent 3 opened on both sides of the distribution cabinet body 1, a dustproof plate 5, which is movably installed on both sides of the distribution cabinet body 1 through a rotating shaft; a support rod 6, which is movably connected to the dustproof plate 5 through fixed shafts on both sides of the bottom of the dustproof plate 5; a support rod 2 7, which is sleeved on the outer surface of the support rod 1 6, and a fixing hole is opened at one end of the support rod 2 7 away from the dustproof plate 5; a limiting groove 8 is opened on the side surface of the support rod 2 7, and a sliding groove is opened between the limiting grooves 8; a limiting rod 9, which is movably installed inside one end of the support rod 1 6 through a rotating shaft, and the limiting rod 9 is rotated through the rotating shaft so that the limiting rod 9 is located in the sliding groove opened by the support rod 2 7, so that the support rod 1 6 and the support rod 2 7 can be stretched, and then the limiting rod 9 is clamped with the limiting grooves 8 at different positions, so that the total length of the support rod 1 6 and the support rod 2 7 changes; a fixing groove 10, which is fixed on the side surface of the distribution cabinet body 1 and connected to the support rod 2 7 Correspondingly, a plurality of fixing holes are opened on both sides of the fixing groove 10, and the end of the support rod 27 is inserted into the fixing groove 10, and then the fixing hole at the end of the support rod 27 is aligned with the fixing hole of the fixing groove 10, and the support rod 27 is fixed to the fixing groove 10 by the fixing bolts, so that the support rod 16 and the support rod 27 form a stable support rod to support the bottom of the dustproof plate 15, so that the dustproof plate 15 and the distribution cabinet body 1 form a stable triangle. The dustproof plate 15 forms an inclined surface due to the support of the support rod 16 and the support rod 27. When it rains, rainwater passes through the obstruction of the dustproof plate 15 and can drip to the ground along the inclined surface of the dustproof plate 15, preventing rainwater from entering the distribution cabinet body 1 from the vent 13, and ensuring that the ventilation holes of the vent 13 still maintain the heat dissipation effect when it rains. By changing the total length of the support rod 16 and the support rod 27, the inclination of the dustproof plate 15 and the distribution cabinet body 1 can be adjusted. And when the installation position on the side of the distribution cabinet body 1 is narrow, the support rod 1 6 and the support rod 2 7 can be shortened to the shortest size, and the end of the support rod 2 7 close to the distribution cabinet body 1 can be moved upward. When the support rod 2 7 moves, the bottom end of the dustproof plate 5 moves inward, thereby changing the inclination of the dustproof plate 5 and the distribution cabinet body 1, narrowing the coverage of the dustproof plate 5 and reducing the space occupied during installation.

[0029] A top cover 2 is fixed on the top of the power distribution cabinet body 1 .

[0030] A filter window 4 is installed at a position corresponding to the ventilation port 3 on the surface of the distribution cabinet body 1, and a mounting groove is fixed on the surface of the distribution cabinet body 1. The filter window 4 can be installed through the mounting groove, so as to facilitate the cleaning and replacement of the filter window 4, and the filter window 4 can reduce the possibility of dust entering the interior of the distribution cabinet body 1 from the ventilation port 3.

[0031] A dust plate 2 11 is connected between the support rod 1 6 and the support rod 2 7. The dust plate 2 11 protects the bottom of the dust plate 1 5. When the support rod 1 6 and the support rod 2 7 are extended and retracted, the dust plate 2 11 can move from the movable groove opened on the side of the support rod 2 7 to ensure the protective effect of the bottom of the dust plate 1 5. Filters 12 are fixed on both sides of the dust plate 1 5. The side of the filter 12 away from the dust plate 1 5 is fixed to the outer wall of the power distribution cabinet body 1, and the bottom of the filter 12 is connected to the surface of the support rod 2 7. An elastic band 13 is fixed to the end of the filter 12 close to the support rod 2 7. When the dust plate 1 5 is retracted inward, the filter 12 begins to rebound and folds the filter 12. The filter 12 is folded and retracted without affecting ventilation and heat dissipation.

[0032] A vent 14 is provided on the surface of the side of the distribution cabinet body 1 away from the cabinet door, and an exhaust fan 15 is installed inside the vent 14. The exhaust fan 15 is used to exhaust air inside the distribution cabinet body 1, thereby accelerating the exchange of hot air inside the distribution cabinet body 1 and cold air outside the distribution cabinet body 1, thereby improving the heat dissipation effect inside the distribution box.

[0033] A ventilation hole 3 16 is provided on the top surface of the power distribution cabinet body 1, and a filter window 4 is also installed inside the ventilation hole 3 16. By providing multiple groups of heat dissipation holes, the efficiency of heat dissipation inside the power distribution cabinet body 1 is improved.

[0034] Working principle: install the power distribution cabinet body 1 at the predetermined position, adjust the dustproof plate 15 according to the space size on both sides of the power distribution cabinet body 1, and then fix the end of the support rod 27 close to the power distribution cabinet body 1 to the fixing groove 10 through fixing bolts. After the support rod 16 and the support rod 27 are fixed to the fixing groove 10, the end of the support rod 16 away from the power distribution cabinet body 1 supports the dustproof plate 15, so that the dustproof plate 15 and the power distribution cabinet body 1 form a stable triangle. After the dustproof plate 15 is supported, the elastic band 13 is stretched, and the filter screen 12 is unfolded accordingly, which is used to fix the power distribution cabinet body 1 and the dustproof plate 15. The gap between the dustproof plate 15 is protected to reduce the entry of dust and impurities. When it rains, the dustproof plate 15 can block the rainwater, so that the rainwater drips to the ground along the inclined surface of the dustproof plate 15, reducing the possibility of rainwater entering the inside of the distribution cabinet body 1 from the support rod 27. In addition, through the space between the dustproof plate 15 and the distribution cabinet body 1, the support rod 27 can still dissipate heat normally when it rains. The exhaust fan 15 installed on the back of the distribution cabinet body 1 can accelerate the exchange of air between the inside of the distribution cabinet body 1 and the outside air, thereby improving the heat dissipation efficiency of the distribution cabinet body 1 and reducing the possibility of overheating of electrical components inside the distribution cabinet body 1.
