Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic cable tray technology, specifically relating to a photovoltaic cable tray cover plate with heat insulation function. Background Technology

[0002] Photovoltaic cable trays are an important component of solar photovoltaic power generation systems, used to install cables for solar photovoltaic modules. Photovoltaic cable tray covers are used to enclose the cable trays. Since photovoltaic cable trays are usually installed outdoors along with the photovoltaic power generation system, the heat insulation performance of the photovoltaic cable tray covers is particularly important.

[0003] Problems with existing technology:

[0004] The prior art, CN221688222U, describes a photovoltaic cable tray cover with heat insulation function, which includes a top plate and an inner plate. The top plate, which is the main body of the cover, is rectangular, and side plates are welded to both sides of the top plate. The inner plate, located below the top plate, is situated between the two side plates, and heat insulation cotton is placed between the inner plate and the top plate. Multiple rectangular grooves are evenly provided on the two side plates, and the multiple rectangular grooves are of the same size. Connecting shafts are welded to the upper ends of the multiple rectangular grooves on the two side plates, and clamping plates are rotatably connected to the multiple connecting shafts. Torsion springs are sleeved on the outer sides of both ends of the multiple connecting shafts, and the two ends of the multiple torsion springs are fixedly connected to the two side plates and the multiple clamping plates, respectively.

[0005] The above-mentioned device achieves the heat insulation effect of the cable tray cover plate only through a single heat insulation cotton. However, in actual use, the heat insulation effect of a single heat insulation cotton is effective. Moreover, photovoltaic cable trays are usually installed outdoors and exposed to direct sunlight. Therefore, the heat insulation cotton alone cannot improve the heat insulation effect of the cable tray cover plate. At the same time, the above-mentioned device uses a torsion spring to clamp the plate to the cable tray. However, in this fastening method, since the sides of the cable tray are usually flat, this clamping method is not reliable and is prone to loosening and falling off. Utility Model Content

[0006] The purpose of this utility model is to provide a photovoltaic cable tray cover with heat insulation function, which can solve the problems of poor heat insulation performance of existing photovoltaic cable tray covers and the unstable installation between the cover and the cable tray, which easily leads to loosening and falling off.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A photovoltaic cable tray cover with heat insulation function includes a cable tray body, a cover body is provided on the top of the cable tray body, and an elastic retaining strip is fixedly connected to the inner side of the cover body;

[0009] The cover plate body is fixedly connected to the bottom by a locking mechanism, which allows the cover plate body to be snapped onto the top of the cable tray body. The cover plate body is equipped with a heat insulation component inside.

[0010] The heat insulation component includes a frame and a heat insulation module. The heat insulation module is fixedly connected to the frame through internally fixed spacers.

[0011] The thermal insulation module includes a surface layer and a core material, wherein the core material is bonded to the surface layer through a reinforcing layer on top.

[0012] The locking mechanism includes a mounting base, a plug, and a limiting arm. A rotating shaft is fixedly connected inside the mounting base for hinged connection of the limiting arm. A torsion spring is sleeved on the outside of the rotating shaft, and one end of the torsion spring abuts against the limiting arm.

[0013] The gap between the elastic clip and the cable tray body forms a groove for the cover plate body to be movably connected to the cable tray body.

[0014] The spacer bars are welded inside the frame and are used for the equidistant distribution of the multiple insulation modules.

[0015] The top and bottom of the reinforcement layer are coated with an adhesive layer for bonding the surface layer and the core material.

[0016] The insert is welded to the bottom of the cover plate body, and the cover plate body is movably connected to the limiting arm through the insert.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention utilizes a heat insulation component fixedly connected inside the main body of the cable tray, with the frame and spacers of the heat insulation component welded to the main body. This heat insulation component effectively improves the overall strength of the main body of the cable tray. Furthermore, because the top of the main body of the cable tray is designed with an arc shape, rainwater can be prevented from accumulating on its surface when the cable tray is used outdoors. Additionally, multiple heat insulation modules are set between the spacers and the frame, and these modules are composed of a surface layer, a reinforcing layer, and a core material to form a composite heat insulation board, thereby effectively improving the heat insulation performance of the cable tray cover.

[0019] This utility model features an insert block installed at the bottom of the cover plate body, and a mounting seat correspondingly installed on the side of the cable tray body. The limiting arm and the mounting seat are hinged together by a pivot. At the same time, one end of a torsion spring sleeved on the outside of the pivot is fixedly connected to the mounting seat, while the other end abuts against the limiting arm. Therefore, when the insert block is inserted into the limiting arm, it will push the limiting arm to unfold outward and pull the torsion spring. After the insert block is inserted into place, the limiting arm can clamp the insert block under the reaction force of the torsion spring. This, together with the elastic retaining strip installed on the inner side of the cover plate body, makes the installation of the cover plate body and the cable tray body more stable and less prone to loosening and falling off.

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figure 1-6 As shown, a photovoltaic cable tray cover with heat insulation function includes a cable tray body 1, a cover body 2 is provided on the top of the cable tray body 1, and an elastic clip 4 is fixedly connected to the inner side of the cover body 2.

[0030] The cover plate body 2 is secured to the top of the cable tray body 1 by a locking mechanism 3 fixedly connected to the bottom. The cover plate body 2 is equipped with a heat insulation component 5 inside.

[0031] The heat insulation component 5 includes a frame 51 and a heat insulation module 53. The frame 51 is fixedly connected to the heat insulation module 53 through a spacer 52 that is fixedly connected inside.

[0032] The thermal insulation module 53 includes a surface layer 531 and a core material 533, the core material 533 being bonded to the surface layer 531 by a reinforcing layer 532 on top of it.

[0033] See attached document Figure 1 , Figure 4 and Figure 5 In this embodiment, the locking mechanism 3 includes a mounting base 31, an insert block 32, and a limiting arm 33. A rotating shaft 34 is fixedly connected inside the mounting base 31 for hinged connection of the limiting arm 33. A torsion spring 35 is sleeved on the outside of the rotating shaft 34, and one end of the torsion spring 35 abuts against the limiting arm 33.

[0034] In the above embodiment, two sets of mirror-arranged limiting arms 33 are installed inside the mounting base 31 via the rotating shaft 34. The other end of the torsion spring 35 is fixedly connected to the mounting base 31. Therefore, under the action of the torsion spring 35, the limiting arms 33 have an elastic reset effect, thereby enabling the insert block 32 to be clamped inside the limiting arms 33.

[0035] Furthermore, the insert block 32 is welded to the bottom of the cover plate body 2, and the cover plate body 2 is movably connected to the limiting arm 33 through the insert block 32.

[0036] Since the mounting base 31 is welded to the side of the cable tray body 1, and the mounting base 31 and the insert block 32 are arranged accordingly, the cover plate body 2 can be installed on the top of the cable tray body 1 by inserting the insert block 32 into the inside of the limiting support arm 33. Since the gap between the elastic strip 4 and the cable tray body 1 forms a groove and is used to connect the cover plate body 2 and the cable tray body 1, the installation of the cover plate body 2 and the cable tray body 1 is more secure and less likely to loosen or fall off under the linkage of the locking mechanism 3 and the elastic strip 4.

[0037] Furthermore, since a guide wheel is rotatably installed inside the limiting arm 33, and the insert 32 is rhomboid, while the two sets of limiting arms 33 form a rhomboid groove, the insert 32 is inserted into the limiting arm 33 more smoothly under the action of the guide wheel. At the same time, the subsequent disassembly of the cover plate body 2 and the cable tray body 1 is also more convenient, thus facilitating subsequent disassembly and maintenance.

[0038] Notably, a through hole 6 is provided on one end surface of the cover plate body 2. A heat-conducting rod or a reinforcing rod can be inserted through the through hole 6. When the heat-conducting rod is installed, it can be used in conjunction with a cooling structure so that the end of the heat-conducting rod is inserted into the cooling structure, thereby transferring the heat of the cover plate body 2 out and preventing the heat from being transferred into the cable tray body 1. When used in conjunction with a reinforcing rod, the strength of the cover plate body 2 can be further improved.

[0039] See attached document Figure 2 , Figure 3 and Figure 6In this embodiment, the spacer strip 52 is welded inside the frame 51 for the equidistant distribution of multiple heat insulation modules 53.

[0040] In the above embodiment, the heat insulation module 53 can be clamped inside the frame 51 by the action of the spacer 52. Since both the frame 51 and the spacer 52 are made of aluminum with sprayed reflective heat insulation coating, they have good heat reflection and heat insulation effects, and can also further improve the overall strength of the cover plate body 2.

[0041] More specifically, the heat insulation module 53 is composed of a surface layer 531, a reinforcing layer 532, and a core material 533. The surface layer 531 is an aluminum plate coated with a reflective heat insulation coating, while the reinforcing layer 532 is a fiberglass mesh cloth used to improve the overall strength of the heat insulation module 53. The core material 533 is polyurethane foam, which has a low thermal conductivity and good adhesion, giving the heat insulation component 5 a good heat insulation effect.

[0042] Furthermore, the top and bottom of the reinforcing layer 532 are coated with an adhesive layer for bonding the surface layer 531 and the core material 533.

[0043] The adhesive layer uses polyurethane adhesive, which has high adhesion, making the connection between the surface layer 531, the reinforcing layer 532 and the core material 533 tighter and more stable, further improving the strength of the heat insulation module 53.

[0044] The working principle of this utility model is as follows: After the locking mechanism 3's insert 32 and mounting base 31 are welded and fixed to the cover plate body 2 and the cable tray body 1 respectively, the insert 32 is inserted between the limiting arms 33 by pressing down the cover plate body 2. Since the insert 32 is diamond-shaped, the limiting arms 33 first unfold outward and pull the torsion spring 35. Then, the limiting arms 33 are reset by the reaction force of the torsion spring 35 to clamp and fix the insert 32, thereby completing the quick and stable installation of the cover plate body 2 and the cable tray body 1.

[0045] During use, the cover body 2 effectively prevents rainwater accumulation due to its arc-shaped top design. Meanwhile, the cover body 2 is equipped with a heat insulation component 5. The frame 51, spacer 52, and heat insulation module 53 of the heat insulation component 5 can improve the strength of the cover body 2 and prevent it from bending. At the same time, the heat insulation module 53 is a composite heat insulation board composed of an aluminum plate surface layer 531, a fiberglass mesh reinforcement layer 532, and a polyurethane foam core material 533, which enables the cover body 2 to have good heat insulation function.

[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
