DETAILED DESCRIPTION

[0022] 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.

[0023] Reference Figure 1-6 A rainproof power distribution cabinet includes a cabinet body 1. The outer walls on both sides of the cabinet body 1 are provided with heat dissipation nets 5 through heat dissipation ports. The outer walls on both sides of the cabinet body 1 are provided with rain covers 2. The rain covers 2 shield the heat dissipation ports and the heat dissipation nets 5 to prevent rainwater from entering therein.

[0024] A rain shield 3 is provided above the cabinet 1 through a mounting rod 6, and a bottom groove 8 is provided on the bottom wall of the rain shield 3. A reciprocating screw 9 is provided in the bottom groove 8 and is rotated by a driving motor. A screw sleeve 13 is provided on a threaded sleeve of the reciprocating screw 9. A scraper 4 is provided on the upper end surface of the rain shield 3, and a movable groove 11 is provided on the scraper 4. A movable rod 10 is provided in the movable groove 11 through an elastic mechanism, and a connecting plate 7 is provided on the movable rod 10. The connecting plate 7 is connected to the screw sleeve 13 through an insertion mechanism.

[0025] The elastic mechanism includes a return spring 12 arranged in the movable groove 11, and the two ends of the return spring 12 are elastically connected to the outer wall of the movable rod 10 and the inner wall of the movable groove 11 respectively. The elastic potential energy provided by the return spring 12 realizes the dragging of the movable rod 10, thereby realizing the dragging of the connecting plate 7, ensuring that the insert block 14 on the outer wall of the screw sleeve 13 can be stably located in the slot 15 on the connecting plate 7.

[0026] The plug-in mechanism includes an insert block 14 arranged on the outer wall of the screw sleeve 13, an arc groove is provided on the surface corresponding to the connecting plate 7 and the screw sleeve 13, and a slot 15 corresponding to the insert block 14 is provided on the inner wall of the arc groove. When the insert block 14 is in the slot 15, when the reciprocating screw 9 rotates, the screw sleeve 13 can move synchronously with the connecting plate 7.

[0027] The rain shield 3 is designed in an arc shape, and the upper end surface of the rain shield 3 is sprayed with anti-rust paint, which is a water-based paint. The water-based metal anti-rust paint uses metal strong chelating agent phytate as the main component and is compounded with several other water-based additives. Phytate is a natural non-toxic organic chemical product extracted from food crops. When it is used as a rust inhibitor for magnetic materials, it can quickly chelate with the metal on the surface to form a dense monomolecular complex protective film, which can effectively inhibit the corrosion of the metal.

[0028] The scraper 4 is designed in an arc shape, and a brush assembly is provided on the surface of the scraper 4 corresponding to the rain shield 3. The arc design effectively prevents rainwater from accumulating on the upper end surface of the rain shield 3, and the brush assembly can clean the accumulated bird droppings or dust impurities.

[0029] A limit rod 16 is provided in the bottom groove 8. The limit rod 16 is arranged parallel to the reciprocating screw 9. The limit rod 16 slides through the screw sleeve 13. The limit rod 16 limits the screw sleeve 13 and effectively prevents the screw sleeve 13 from rotating with the reciprocating screw 9 when the reciprocating screw 9 rotates, thereby playing a limiting role.

[0030] When the utility model is used, the rain cover 2 shields the heat dissipation port and the heat dissipation net 5, and the rain shield 3 realizes the rain shielding operation, which is convenient for an operator to stand below and open the cabinet door of the cabinet body 1 when it rains.

[0031] Birds often stand on the rain shield 3 and impurities such as bird droppings or fallen leaves are easily accumulated. Long-term accumulation will destroy the anti-rust paint on the rain shield 3. At this time, starting the drive motor can drive the reciprocating screw 9 to rotate. When the reciprocating screw 9 rotates, the screw sleeve 13 on its outer wall can drive the connecting plate 7 and the scraper 4 to move. The scraper 4 cooperates with the brush assembly to clean and scrape the upper end surface of the rain shield 3 to ensure the cleanliness of the upper end surface of the rain shield 3.

[0032] After pulling the connecting plate 7 downward, the movable rod 10 drags the return spring 12 and disengages the slot 15 from the plug 14, thereby releasing the limiting connection of the scraper 4 relative to the rain shield 3. The scraper 4 can be disassembled relative to the rain shield 3, making it convenient to clean the scraper 4 or replace the brush assembly.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
