Description

A photovoltaic junction box mounting base with waterproof drainage groove Technical Field

[0001] This utility model relates to the field of photovoltaic junction box technology, and in particular to a photovoltaic junction box mounting base with a waterproof drainage groove. Background Technology

[0002] A photovoltaic junction box is a connecting device between a solar cell array composed of solar cell modules and a solar charging control device. Its main function is to connect and protect the solar photovoltaic modules, connect the power generated by the solar cells to external lines, and conduct the current generated by the photovoltaic modules.

[0003] The existing patent document CN220798213U discloses a photovoltaic junction box welded with resistance welding of tin sheets. Through the action of the spring in the base cavity, after the box cover is closed, the waterproof plate will move upward and connect with the sealing groove on the inner side of the box cover, which improves the sealing performance of the photovoltaic junction box, making the inside of the junction box less susceptible to moisture and effectively protecting the electronic components inside the junction box, with good protection effect. Through the action of the telescopic spring in the groove cavity, the two sets of locking blocks can be moved in opposite directions, that is, the two sets of locking blocks can be connected with or disengaged from the blocking groove, realizing the quick assembly and disassembly of the connector and the fixing seat, facilitating the opening and closing of the box cover, and making subsequent maintenance and replacement convenient.

[0004] Although the photovoltaic junction box made by resistance welding of the tin sheet mentioned above can solve the corresponding technical problems, the waterproof plate will move upward and connect with the sealing groove on the inner side of the box cover after the box cover is closed due to the action of the spring in the base cavity. However, the elasticity of the spring will gradually decrease after long-term use, making it difficult for the waterproof plate to connect with the sealing groove on the side of the box cover in the later stage, thus affecting the waterproof effect.

[0005] To address this, a photovoltaic junction box mounting base with a waterproof drainage channel is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a photovoltaic junction box mounting base with a waterproof drainage groove to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0012] As a preferred technical solution, the wire assembly includes a connecting tube fixedly extending through the outer shell, the inner cavity of the connecting tube communicating with the inner cavity of the substrate, and a waterproof sleeve threaded onto the surface of the connecting tube.

[0013] As a preferred technical solution, the drainage component A includes a frame A fixedly connected to the outer surface of the substrate and arranged along its long side. A guide groove A is provided on the side of the frame A away from the connecting pipe. Several water outlet holes are provided at equal intervals on the frame A. The guide groove A is connected to the inner cavity of the corresponding water outlet hole.

[0014] As a preferred technical solution, the flow guide B includes a frame B fixedly connected to the outer surface of the substrate and arranged along its short side. The frame B has a flow guide groove B facing the same direction as the flow guide groove A. At least one flow guide groove B is formed on the frame B. The frame B is connected to the inner cavity of the corresponding water outlet hole.

[0015] As a preferred technical solution, both ends of the frame B are fixedly connected to U-shaped frames, the inner wall surface of the U-shaped frames is in contact with the connecting buckle, and the end of the U-shaped frame away from the frame B is fixedly connected to the adjacent frame A.

[0016] As a preferred technical solution, the top horizontal lines of both frame A and frame B are higher than the top horizontal line of the substrate.

[0017] As a preferred technical solution, the reinforcing component includes an inner shell fixedly connected to the top of the substrate and located in the inner cavity of the outer shell. An annular cavity is formed between the inner shell and the reinforcing ribs. Several regularly distributed reinforcing ribs are fixedly connected inside the annular cavity. A through groove communicating with the inner cavity of the connecting pipe is opened on the surface of the inner shell.

[0018] As a preferred technical solution, the horizontal lines on the top surfaces of the reinforcing ribs, inner shell, and substrate increase sequentially.

[0019] This utility model has at least the following beneficial effects:

[0020] This application, by adding a flow guiding component to the outer surface of the photovoltaic junction box mounting base, allows rainwater and other liquids to be directly discharged along frame A, frame B, and the water outlet when the photovoltaic junction box mounting base is installed horizontally; when the photovoltaic junction box mounting base is installed vertically, rainwater and other liquids can flow directly down along the flow guiding component A and flow guiding component B, making it difficult for them to seep in through the joint between the photovoltaic junction box mounting base and the box cover. This effectively prevents short circuits in the internal wiring of the photovoltaic junction box mounting base, improves safety, and eliminates the need for a spring structure, thus effectively avoiding the phenomenon of reduced waterproofing effect due to spring failure.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4. An embodiment of this utility model provides a photovoltaic junction box mounting base with a waterproof drainage channel, including a photovoltaic junction box mounting base body 100, a wire assembly 200 for wires to pass through, a drainage component 300 to ensure smooth drainage of liquid from the photovoltaic junction box mounting base body 100, and a reinforcing component 400 to enhance the strength and rigidity of the photovoltaic junction box mounting base body 100. The wire assembly 200 is located on one side of the photovoltaic junction box mounting base body 100, and the drainage component 300 is located on the photovoltaic junction box mounting base. On the main body 100, the reinforcing component 400 is disposed in the inner cavity of the photovoltaic junction box mounting base main body 100; the flow guiding component 300 includes a flow guiding component A310 disposed on the photovoltaic junction box mounting base main body 100, two flow guiding components A310 are symmetrically arranged along the short side midline of the photovoltaic junction box mounting base main body 100, and a flow guiding component B320 is provided at the adjacent end of the two flow guiding components A310. The flow guiding components A310 and B320 are connected around the periphery in sequence and form a rectangular frame structure. Both the flow guiding component A310 and the flow guiding component B320 are provided with water outlet holes 330.

[0028] The photovoltaic junction box mounting base body 100 includes a base plate 110. A housing 120 is fixedly connected to one side of the base plate 110. A set of connecting buckles 130 is provided on both sides of the housing 120. Each set of connecting buckles 130 has two symmetrically arranged about the center line of the short side of the housing 120. Two wire assemblies 200 are symmetrically arranged along the long side of the housing 120. A reinforcing assembly 400 is provided in the inner cavity of the housing 120. When the photovoltaic junction box mounting base body 100 is used in conjunction with its matching box cover, the solar energy can play a role in connecting and protecting the photovoltaic module.

[0029] The conductor assembly 200 includes a connecting tube 210 fixedly extending through the housing 120. The inner cavity of the connecting tube 210 communicates with the inner cavity of the substrate 110. A waterproof sleeve 220 is threaded onto the surface of the connecting tube 210. The end of the conductor can be inserted into the photovoltaic junction box mounting base body 100 for connection through the connecting tube 210. The waterproof sleeve 220 can improve the sealing between the connecting tube 210 and the conductor, which helps to improve the waterproof performance.

[0030] The flow guide A310 includes a frame A311 fixedly connected to the outer surface of the substrate 110 and arranged along its long side. A flow guide groove A312 is provided on the side of the frame A311 away from the connecting pipe 210. Several water outlet holes 330 are equally spaced on the frame A311. The flow guide groove A312 is connected to the inner cavity of the corresponding water outlet hole 330.

[0031] The drainage component B320 includes a frame B321 fixedly connected to the outer surface of the substrate 110 and arranged along its short side. A drainage groove B322 with the same orientation as the drainage groove A312 is opened on the frame B321. At least one drainage groove B322 is opened on the frame B321. The frame B321 is connected to the inner cavity of the corresponding water outlet 330. Through the combined use of the drainage component A310, the drainage component B320 and the water outlet 330, the rainwater and other liquids on the photovoltaic junction box can be drained smoothly.

[0032] Both ends of the frame B321 are fixedly connected to a U-shaped bracket 323. The inner wall of the U-shaped bracket 323 contacts the connecting buckle 130. The end of the U-shaped bracket 323 away from the frame B321 is fixedly connected to the adjacent frame A311. The U-shaped bracket 323 can connect the frame B321 and the frame A311 and avoid the connecting buckle 130, so as to prevent the connecting buckle 130 and the flow guide component 300 from blocking each other and affecting normal use.

[0033] The top horizontal lines of both frame A311 and frame B321 are higher than the top horizontal line of substrate 110. The height difference allows the flow guiding component 300 to greatly block the seam formed after the photovoltaic junction box mounting base body 100 is connected to the box cover. This allows rainwater and other liquids to flow down along the flow guiding component 300 when the photovoltaic junction box mounting base body 100 is installed vertically, thus effectively preventing rainwater and other liquids from seeping into the photovoltaic junction box mounting base body 100 from the seam.

[0034] The reinforcing component 400 includes an inner shell 410 fixedly connected to the top of the substrate 110 and located in the inner cavity of the outer shell 120. An annular cavity is formed between the inner shell 410 and the reinforcing ribs 420. Several regularly distributed reinforcing ribs 420 are fixedly connected inside the annular cavity. A through groove 411 communicating with the inner cavity of the connecting pipe 210 is opened on the surface of the inner shell 410. The reinforcing component 400 can enhance the strength and rigidity of the photovoltaic junction box mounting base body 100 without increasing the wall thickness of the photovoltaic junction box mounting base body 100, thereby saving the amount of manufacturing materials, reducing weight, and lowering costs.

[0035] Among them, the horizontal lines on the top surfaces of the reinforcing rib 420, the inner shell 410, and the substrate 110 increase sequentially, so that the lower part of the sealing ring gasket of the cover, which matches the photovoltaic junction box mounting base body 100, can be placed in the annular cavity and contact the top of the reinforcing rib 420, thereby improving the connection and sealing between the photovoltaic junction box mounting base body 100 and the cover, and further improving the waterproof effect.

[0036] The working principle of this utility model is as follows: the wires of the solar photovoltaic panel are introduced into the inner shell 410 through the wire assembly 200. After the wiring is completed in the inner shell 410, the outer shell 120 is connected to the matching cover through the connecting buckle 130, so that the sealing gasket on the cover can be placed in the annular cavity and contact the reinforcing rib 420 to achieve the sealing operation. Then the photovoltaic junction box mounting base body 100 can be fixed in the required position. When the photovoltaic junction box mounting base body 100 is installed and fixed in a horizontal direction, rainwater and other liquids can flow directly into the frame A311 and frame B321, and finally be discharged through the water outlet 330. When the photovoltaic junction box mounting base body 100 is installed in a vertical direction, rainwater and other liquids can flow directly down the surface of the frame A311 and frame B321, and it is difficult for them to seep in through the joint between the photovoltaic junction box mounting base body 100 and the cover, effectively preventing short circuits in the internal wiring of the photovoltaic junction box mounting base body 100 and improving the safety of use.

[0037] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
