Detailed Description

The present application is described in further detail below with reference to the attached drawings.

In order to more clearly understand the technical solution shown in the embodiment of the present application, first, the operation principle of the existing inverter mounting box for a photovoltaic panel is described.

The inverter is an important electrical device in a photovoltaic system, and generally needs to be installed in an installation box to reduce erosion of the inverter caused by wind, sand, rain and the like. A common installation box is a common cuboid iron sheet cabinet, and an inverter is installed in the iron sheet cabinet.

From the user's angle, cuboid iron sheet cabinet waterproof nature is relatively poor, and its structure is unfavorable for the drainage, causes some horizontal plane ponding easily, causes the install bin to corrode, and then influences the working life of dc-to-ac converter.

Please refer to fig. 1, for the inverter installation box for a waterproof photovoltaic panel disclosed in the embodiment of the present application, which comprises a box body 1, a mounting opening for installing an inverter is opened on the front surface of the box body 1, a box cover 11 is hinged on the mounting opening of the box body 1, a wiring hole 12 is opened on the bottom surface of the box body 1, a mounting frame 13 is fixedly connected in the box body 1, a connecting piece 2 is fixedly connected to the side surface of the box body 1, a through hole is opened at one end of the connecting piece 2 away from the box body 1, a baffle 3 is fixedly connected to the top end of the box body 1, the baffle 3 is downward inclined from the back surface of the box body 1 to the front surface of the box body 1, two sides of the baffle 3 are downward inclined toward the two sides of the box body 1, a sealing plate 4 is fixedly connected to the top end of the sealing plate 4 away from the top end of the box body 1 and is fixedly connected to the baffle 3, and the baffle 3 is located at the edge parts of the front surface and the two sides of the box body 1 and protrudes out of the box body 1.

Specifically, baffle plates 3 inclined to the front and two sides of the box body 1 are mounted on the box body 1, a sealing plate 4 is mounted in a gap formed between the front of the box body 1 and the baffle plates 3, and the edge parts of the baffle plates 3 positioned on the front and two sides of the box body 1 protrude out of the box body 1.

Like this, because baffle 3 is located the positive of box 1 and the marginal portion protrusion box 1 of both sides, can reduce the rainwater and fall to the possibility of box 1, baffle 3 is to box 1 front and two side slopes simultaneously, flows away along the inclined plane when having the rainwater to fall, reduces the possibility that the rainwater gathers, installs shrouding 4 in the space that box 1 front and baffle 3 formed, reduces the rainwater and gathers the possibility at box 1 top through this space, reduces the rainwater infiltration box 1 and erodes the possibility of inverter.

In some feasible modes, box 1 is the cuboid form, the rectangle installing port has been seted up to box 1 one side, installing port department articulates there is the case lid 11 that seals the installing port, wiring hole 12 that is used for the dc-to-ac converter wiring is seted up to box 1 bottom surface, fixedly connected with is used for fixed inverter mounting bracket 13 in the box 1, mounting bracket 13 includes the C shaped steel that two parallels and level were arranged, connecting piece 2 is the rectangle slice, welded fastening is in box 1 side and back handing-over department, connecting piece 2 is provided with four, two sides of box 1 equipartition respectively have two connecting pieces 2, box 1 passes through connecting piece 2 and bolt fastening in wall body or other positions. Baffle 3 is the symmetry piece of bending, welds in 1 top of box, and baffle 3 openly is the downward sloping to box 1 from the 1 back of box. The closing plate 4 is welded on the baffle 3 and the box body 1 and is used for closing the gap between the baffle 3 and the front surface of the box body 1.

Further description is provided below with respect to specific usage scenarios.

When the inverter is used, the connecting piece 2 is fixed on a wall body or other positions through bolts, and the inverter is installed on the installation frame 13. When rainwater exists, the rainwater falls on the baffle 3, slides off through the inclined plane of the baffle 3, and meanwhile, the sealing plate 4 seals the gap between the baffle 3 and the front surface of the box body 1, so that the accumulation of the rainwater on the box body 1 is reduced, and the possibility that the rainwater permeates into the box body 1 to corrode the inverter is reduced.

As a specific implementation manner of the waterproof inverter installation box for the photovoltaic panel provided by the application, the lower side wall of the installation opening is an inclined plane inclined downwards from inside to outside, and the lower side surface of the box cover 11 is an inclined plane matched with the lower side wall of the installation opening.

When rainwater falls from the front of the box body 1 by combining a specific use scene, the rainwater can be gathered and seeped into the box body through the lower side wall of the mounting opening, and the lower side wall of the mounting opening is an inclined plane inclined downwards from inside to outside, so that the rainwater can fall along the inclined plane, and the possibility of rainwater gathering and seeping into the box body is reduced.

As another specific embodiment of the inverter installation box for the waterproof photovoltaic panel provided by the application, a sealing strip is fixedly connected to the side surface of the box cover 11.

It should be understood that the sealing strip seals the gap between the cover 11 and the housing 1, thereby further reducing the infiltration of rain water and thus the corrosion of the inverter.

As another embodiment of the inverter installation box for a waterproof photovoltaic panel, please refer to fig. 1 and 2, a wire sealing ring 121 is installed at the wiring hole 12.

It should be understood that the wire sealing ring 121 seals the wire hole 12 and the cable, so as to reduce dust entering the box body 1, further protect the inverter, and reduce corrosion to the inverter.

Further, one end of the wire sealing ring 121 is fixedly connected with a hose 122.

Further, the hose 122 is a heat shrinkable tube.

It should be understood that after the cable is connected, the heat-shrinkable tube shrinks due to the heat-shrinkable property of the heat-shrinkable tube, so that the end of the flexible tube 122 away from the wire sealing ring 121 shrinks to fit the cable, thereby further reducing the possibility of dust and the like entering the box body 1.

As another specific embodiment of the inverter installation box for the waterproof photovoltaic panel provided by the application, a plurality of heat dissipation plates 14 are fixedly connected to the back surface of the box body 1, and the heat dissipation plates 14 are uniformly arrayed on the back surface of the box body 1.

It should be understood that the inverter is used as an electrical appliance, and when the inverter is used, a certain amount of heat is generated, and the heat is dissipated through the heat dissipation plate 14, so that the heating of the inverter is reduced, and the service life of the inverter is prolonged.

Further, a fan 15 is installed on one side of the box body 1, and an air port of the fan 15 is over against the side face of the heat dissipation plate 14.

It should be understood that the fan 15 increases the air circulation speed around the heat dissipation plate 14, so as to increase the heat dissipation, further reduce the inverter heating, and increase the inverter service life.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
