[0001] The utility model relates to the technical field of outdoor power distribution cabinets, in particular to an anti-seepage outdoor power distribution cabinet. Background Art

[0002] At present, the power distribution cabinets used for outdoor use generally have strong anti-seepage performance, but the ventilation effect inside is reduced, which can easily cause the internal temperature of the power distribution cabinet to rise during actual use, thereby affecting the normal use of the internal components of the power distribution cabinet, making it inconvenient for actual use.

[0003] In order to solve the above technical problems, a Chinese utility model patent with authorization announcement number CN219106870U discloses an outdoor anti-seepage distribution cabinet, including a cabinet body, a sealing plate movably connected to the inner cavity of the cabinet near the bottom, a plurality of ventilation holes are provided on the sealing plate and the bottom of the cabinet body, two springs are fixedly connected to the bottom of the sealing plate, the bottom end of the spring is fixedly connected to the bottom of the inner wall of the cabinet, and a sealing mechanism is provided at the bottom of the sealing plate, the sealing mechanism includes a vertical rod, the top end of the vertical rod is fixedly connected to the bottom of the sealing plate, a through hole is provided at the bottom of the cabinet body near the center, the bottom end of the vertical rod passes through the through hole and is fixedly connected to a water-absorbing pad, the bottom of the inner wall of the cabinet body and the bottom of the sealing plate are fixedly connected to a plurality of sealing blocks, and the outer sides of the plurality of sealing blocks and the outer sides of the vertical rods are fixedly connected to sealing pads.

[0004] The principle is as follows: when rainwater accumulates, the absorbent pad absorbs the accumulated water at the bottom. At this time, the weight of the absorbent pad increases continuously and it moves downward, thereby driving the sealing plate on the vertical rod to move. The sealing plate drives the ventilation holes and the sealing block on it to move downward together. At the same time, the sealing plate compresses two springs. At this time, the sealing block at the bottom of the inner wall of the cabinet and the sealing pad on the outside seal the ventilation holes on the sealing plate. At the same time, the sealing block and the sealing pad on the sealing plate seal the ventilation holes at the bottom of the cabinet. However, the above-mentioned prior art has the following problems: the absorbent pad is arranged at the bottom of the cabinet, and rainwater is absorbed by the absorbent pad after accumulation, so that the absorbent pad becomes heavy, thereby driving the sealing plate to move and block the ventilation holes. In actual use, rainwater is usually mixed with soil and dust on the ground to form muddy water with solid particles. These solids will adhere to the surface of the absorbent pad for a long time. Over time, the weight of the absorbent pad gradually becomes heavier, making the height of the sealing plate lower than the initial height, and the ventilation holes gradually become smaller, affecting the heat dissipation of the cabinet.

DETAILED DESCRIPTION

[0039] 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.

[0040] See also Figure 1-5 The utility model provides a technical solution: an anti-seepage outdoor power distribution cabinet, comprising:

[0041] The cabinet body 1 has a first ventilation hole 3 on its surface;

[0042] A sealing plate 5, which is in contact with the cabinet 1 and has a second ventilation hole 6 matching the first ventilation hole 3;

[0043] A slide post 8 is slidably disposed in a slide groove 9 provided at the bottom end of the cabinet 1, and a top end of the slide post 8 is connected to a bottom end of the sealing plate 5;

[0044] A water-absorbing pad 10 connected to the bottom end of the sliding column 8;

[0045] The elastic structure is used to drive the sealing plate 5 to reset after the water-absorbing pad 10 loses water and weight, so as to ensure that the first ventilation hole 3 and the second ventilation hole 6 are aligned; the elastic structure is a spring 7, which has a plurality of springs, and the top end of the spring 7 is fixed to the bottom end of the sealing plate 5, and the bottom end of the spring 7 is fixed to the bottom end of the inside of the cabinet 1;

[0046] The anti-seepage outdoor distribution cabinet also includes:

[0047] A box body 11 is disposed at the bottom of the cabinet body 1 and covers the water-absorbing pad 10, and a filtering hole 12 is opened at the bottom of the box body 11;

[0048] The movable plate 16 is arranged in the box body 11, and the movable plate 16 matches the sealing plate 5 in shape; the upper end of the movable plate 16 is provided with a side groove 14 matching the sliding column 8;

[0049] Brush 17, which is arranged on the side where the movable plate 16 and the sealing plate 5 are in contact; the side of the movable plate 16 close to the filter hole 12 is also provided with bristles 17, and the bristles 17 are in contact with the upper surface of the filter hole 12;

[0050] A driving structure, which is used to drive the movable plate 16 and the water-absorbing pad 10 to move relative to each other; the driving structure includes: a motor 18, which is arranged on the side wall of the box body 11; a screw rod 19, which is connected to the output shaft of the motor 18; a first connecting block 20, which is arranged on the side of the movable plate 16, and a screw rod groove 21 matching the screw rod 19 is opened on the surface of the first connecting block 20; a guiding structure, which is used to guide the movable plate 16 to move linearly; the guiding structure includes: a second connecting block 23, which is arranged on the side of the movable plate 16; a guide rod 22, one end of which is fixed to the inner wall of the box body 11, and the guide rod 22 is slidably matched with a guide groove 24 opened on the surface of the second connecting block 23;

[0051] The above technical solution can be used to filter rainwater and clean the water-absorbing pad 10. When it rains, rainwater accumulates at the bottom of the cabinet 1. When the rainwater accumulates to a certain height, it enters the box 11 through the filter holes 12 at the bottom of the box 11, so that the rainwater contacts the water-absorbing pad 10. The water-absorbing pad 10 becomes heavier after absorbing water. Until the downward pressure of the water-absorbing pad 10 on the sealing plate 5 is greater than the elastic force of the spring 7 on the sealing plate 5, the water-absorbing pad 10 drives the slide column 8 to move down along the slide groove 9, and the slide column 8 drives the sealing plate 5 to move down, so that the second ventilation hole 6 on the surface of the sealing plate 5 is staggered with the first ventilation hole 3 on the side wall of the cabinet 1, so that the first ventilation hole 3 is blocked, preventing rainwater from entering the cabinet 1. Due to the provision of the filter holes 12, soil particles or other solid impurities in the rainwater can be prevented from entering the box 11, and these solid impurities can be prevented from remaining in the water-absorbing pad 10.

[0052] When the weather clears up, the temperature rises, thereby evaporating the water in the water-absorbing pad 10. At this time, the weight of the water-absorbing pad 10 decreases until the downward pressure of the water-absorbing pad 10 on the sealing plate 5 is less than the elastic force of the spring 7 on the sealing plate 5. The sealing plate 5 is reset under the elastic force of the spring 7, so that the second ventilation hole 6 on the surface of the sealing plate 5 is aligned with the first ventilation hole 3 on the side wall of the cabinet 1, and the inside of the cabinet 1 is circulated with the outside air, thereby facilitating heat dissipation;

[0053] After being used for a period of time, the surface of the water-absorbing pad 10 inevitably absorbs impurities, and the filter holes 12 contain a large amount of solid impurities. At this time, the motor 18 is started to drive the screw rod 19 to rotate intermittently forward and reversely, and the screw rod 19 drives the first connecting block 20 to slide, and the first connecting block 20 drives the movable plate 16 to slide. The movable plate 16 slides straight along the guide rod 22, and the bristles 17 on the surface of the movable plate 16 rub the outer surface of the water-absorbing pad 10 and the filter holes 12, so as to clean the outer surface of the water-absorbing pad 10 and dredge the filter holes 12 at the same time, so as to avoid the weight increase of the water-absorbing pad 10 after a long period of use, resulting in a gradual reduction of the first ventilation hole 3, and to avoid the filter holes 12 being blocked and affecting the rainwater entering the box body 11.

[0054] Further, such as Figure 1 and Figure 2As shown, a rain shield 4 is provided outside the first ventilation hole 3, and a rain cover 15 is provided outside the motor 18;

[0055] The above technical solution can prevent rainwater from entering the cabinet 1 through the first ventilation hole 3 .

[0056] Further, such as Figure 1 and Figure 2 As shown, the outer hinge of the box body 11 is connected with a box door 13;

[0057] The above technical solution can be used to conveniently open the box door 13 to clean and maintain the internal structure of the box body 11.

[0058] Further, such as Figure 2 As shown, an inner cabinet 2 is arranged inside the cabinet body 1;

[0059] By adopting the above technical solution, the electrical components can be installed in the inner cabinet 2, further improving the waterproof effect of the electrical components.

[0060] Working principle: When it rains, rainwater accumulates at the bottom of the cabinet 1. When the rainwater accumulates to a certain height, it enters the box 11 through the filter hole 12 at the bottom of the box 11, so that the rainwater contacts the water-absorbing pad 10. The water-absorbing pad 10 becomes heavier after absorbing water, until the downward pressure of the water-absorbing pad 10 on the sealing plate 5 is greater than the elastic force of the spring 7 on the sealing plate 5, the water-absorbing pad 10 drives the slide column 8 to move down along the slide groove 9, and the slide column 8 drives the sealing plate 5 to move down, so that the second ventilation hole 6 on the surface of the sealing plate 5 is staggered with the first ventilation hole 3 on the side wall of the cabinet 1, so that the first ventilation hole 3 is blocked, preventing rainwater from entering the interior of the cabinet 1. Due to the provision of the filter hole 12, soil particles or other solid impurities in the rainwater can be prevented from entering the box 11, and these solid impurities are prevented from remaining in the water-absorbing pad 10.

[0061] When the weather clears up, the temperature rises, thereby evaporating the water in the water-absorbing pad 10. At this time, the weight of the water-absorbing pad 10 decreases until the downward pressure of the water-absorbing pad 10 on the sealing plate 5 is less than the elastic force of the spring 7 on the sealing plate 5. The sealing plate 5 is reset under the elastic force of the spring 7, so that the second ventilation hole 6 on the surface of the sealing plate 5 is aligned with the first ventilation hole 3 on the side wall of the cabinet 1, and the inside of the cabinet 1 is circulated with the outside air, thereby facilitating heat dissipation;

[0062] After being used for a period of time, the surface of the water-absorbing pad 10 inevitably absorbs impurities, and the filter holes 12 contain a large amount of solid impurities. At this time, the motor 18 is started to drive the screw rod 19 to rotate intermittently forward and reversely, and the screw rod 19 drives the first connecting block 20 to slide, and the first connecting block 20 drives the movable plate 16 to slide. The movable plate 16 slides straight along the guide rod 22, and the bristles 17 on the surface of the movable plate 16 rub the outer surface of the water-absorbing pad 10 and the filter holes 12, so as to clean the outer surface of the water-absorbing pad 10 and dredge the filter holes 12 at the same time, so as to avoid the weight increase of the water-absorbing pad 10 after a long period of use, resulting in a gradual reduction of the first ventilation hole 3, and to avoid the filter holes 12 being blocked and affecting the rainwater entering the box body 11.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
