Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.

As shown in fig. 1 and 2, the rain-proof low-voltage power distribution cabinet according to the technical scheme of the invention comprises a ceiling 1 and a cabinet body 2 arranged in the coverage range of the lower side of the ceiling 1. A heat dissipation seam 3 is arranged between the top of the cabinet body 2 and the ceiling 1, and the lower edge of the ceiling 1 is lower than the position of the heat dissipation seam 3. Heat dissipation seam 3 is used for the heat dissipation, simultaneously, because the cover of ceiling 1 and heat dissipation seam 3 hide in the within range that the ceiling covered, under the normal condition, rainwater lateral motion strikes ceiling 1 by the separation under the wind-force effect, can not follow heat dissipation seam 3 and get into in the cabinet body 2, so, heat dissipation seam 3 here can satisfy heat dissipation and rainproof requirement simultaneously for this technical scheme's switch board has rain-proof heat dissipation function.

As shown in fig. 2 and fig. 3, in the present technical solution, the cross section of the ceiling 1 has a herringbone structure, the ceiling 1 includes two

inclined plates

11 and 12 forming the herringbone structure, and a fixed baffle 13 and a movable baffle 14 disposed at two ends of the inclined plate 11/12, the fixed baffle 13 and the movable baffle 14 are vertically disposed and connected with the inclined plate 11/12. The fixed baffle 13 and the movable baffle 14 are both triangular and adapted to the cross-sectional area of the chevron shape enclosed by the two sloping plates 11/12. Adopt chevron shape ceiling 1, can be quick when the rainfall discharge the rainwater downwards, avoid the rainwater to stop on the electric cabinet. Meanwhile, the fixed baffle 13 and the movable baffle 14 realize the rain shielding of the front and back positions of the cabinet body. The ceiling 1 realizes a semi-closed area with a heat dissipation seam 3 at the top of the cabinet body 2, and simultaneously satisfies heat dissipation and rain prevention.

As shown in fig. 2, the fixed baffle 13 is welded to the two sloping plates 11/12, one side of the movable baffle 14 is hinged to one of the sloping plates 11, and the other side of the movable baffle is connected to the sloping plate 12 by a pin. The lower edge of the fixed baffle 13 is lower than the upper edge of the back plate 23 of the cabinet body 2, so that the heat dissipation seam 3 at the top of the back plate is rainproof. However, since the cabinet door 24 needs to be opened periodically, the movable flap 14 is provided to block and protect the heat dissipating slits 3 at the top of the cabinet door 24 from rain. When the cabinet door 24 needs to be opened, the movable baffle 14 is firstly opened forwards, and then the cabinet door 24 is opened, so that the problem of interference when the cabinet door 24 is opened is avoided.

As shown in fig. 2 and 3, the cabinet 2 includes a cabinet door 24, a back panel 23, a bottom panel 25 and two side panels 21/22. The two

side plates

21 and 22 are fixedly connected with the two sloping plates 11/12 respectively, and the back plate 23 and the cabinet door 24 are arranged close to the fixed baffle 13 and the movable baffle 14 respectively. The back panel 23 and both side panels 21/22 each include an inner laminate 400 and an outer laminate 40. The inner plate 400 and the outer plate 40 each include an upper connection plate 41, a lower connection plate 42, and an intermediate heat dissipation plate 43. Utilize middle heating panel 43 to realize the heat dissipation, adopt the structure of inner plating 400 and outer plywood 40, ensure to realize waterproofly under the radiating prerequisite of assurance, avoid the rainwater to get into inside the cabinet body 2. The upper and lower connecting

plates

41 and 42 serve the purpose of connecting the intermediate heat sink 43 and the ceiling 1 to the base plate 25.

As shown in fig. 4 and 5, the intermediate heat dissipation plate 43 of the present embodiment is formed by uniformly arranging a plurality of U-shaped channel plates 431, a heat dissipation groove 432 is left between the two U-shaped channel plates 431, and the upper and lower ends of the back surface of the U-shaped channel plate 431 are respectively connected to the upper connection plate 41 and the lower connection plate 42 by welding. The heat dissipation grooves 432 and the U-shaped groove plates 431 on the inner plate 400 and the outer plate 40 are arranged in a staggered mode, and the U-shaped groove plates 431 of the outer plate 40 wrap the heat dissipation grooves 432 on the inner plate 400. In this structure, the heat in the cabinet 2 is dissipated outwards through the heat dissipating grooves 432, and the U-shaped groove plate 431 of the outer plate 40 blocks the rainwater from entering the cabinet 2 through the heat dissipating grooves 432 of the inner plate 400. When it rains, rainwater drifts on the outer plate 40, and then flows downwards from the U-shaped groove plate 431 of the inner plate 400 to the ground directly between the inner plate 400 and the outer plate 40 as the outer plate 40 flows downwards.

In the technology, the inner layer board 400 forms a power distribution inner cabinet with heat dissipation capability, and then the power distribution inner cabinet formed by the inner layer board 400 is subjected to rainproof operation by combining the outer layer board 40.

As shown in fig. 3, the top of the upper connecting plate 41 of the two side plates 21/22 is provided with a connecting leg 5, the two side plates 21/22 are connected with the ceiling 1 through the connecting leg 5, and the height of the connecting leg 5 is the height of the heat dissipating seam 3. The two ends of the inner layer plate and the outer layer plate of the back plate 23 are respectively welded with the inner layer plate and the outer layer plate of the two side plates, and the cabinet door is hinged with the outer layer plate of the side plate.

Technical solution of the invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive method concept and technical solution, or to apply the inventive concept and technical solution to other occasions without modification.
