[0021] The core of the present invention is to provide a photovoltaic cable trough for a W-shaped water channel bracket, which solves the technical problem of cable damage caused by local heating caused by bundling cables and realizes effective protection of photovoltaic cables.

[0022] It should be noted that the directional words "up" and "down" in this article refer to Figure 1 The directional words appearing in this article are established based on the customary usage of those skilled in the art and the drawings in the specification, and their appearance shall not affect the protection scope of the present invention.

[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of a photovoltaic cable trough for a W-shaped water guide trough support provided by the present invention; Figure 2 A schematic diagram of a photovoltaic cable trough for a W-type water guide trough support provided by the present invention in an installed state; Figure 3 for Figure 2 Installation diagram of the photovoltaic cable trough and W water guide bracket.

[0025] The present invention provides a photovoltaic trough for a W-shaped water-conducting trough support, comprising a photovoltaic trough body 2, wherein the photovoltaic trough body 2 is specifically two groups, which are respectively installed on both sides of the W-shaped water-conducting trough support 1. The number of photovoltaic trough bodies 2 in each group can be one, or two or more. The number of photovoltaic trough bodies 2 installed can be reduced by increasing the length of the photovoltaic trough body 2 in the supporting direction, or the size of the photovoltaic trough body 2 can be reduced by increasing the number of photovoltaic trough bodies 2, so as to achieve lightweight installation. When there are multiple photovoltaic trough bodies 2, the photovoltaic trough bodies 2 are arranged along the extension direction of the W-shaped water-conducting trough support 1 to achieve the flat laying of the photovoltaic cable 3. Preferably, the photovoltaic trough bodies 2 are evenly distributed on the W-shaped water-conducting trough support 1.

[0026] Specifically, the photovoltaic trough body 2 includes a mounting frame 21 and a bracket 22 fixedly mounted on the mounting frame 21. The mounting frame 21 can be detachably fixed on the W water trough bracket 1. The mounting frame 21 and the W water trough bracket 1 can be connected by a hook, bolted, or hung on the W water trough bracket 1; the bracket 22 is provided with an opening structure. After being firmly installed, the photovoltaic cable 3 is neatly placed in the bracket 22.

[0027] In order to prevent dust and rainwater from falling into the bracket 22, a cover plate 23 can be set on the upper uncovered bracket 22. The bracket 22 and the cover plate 23 cover the cable therein to play a role in waterproofing, moisture-proofing and dust-proofing to protect the photovoltaic cable 3; further, a cover plate 23 can be installed on other brackets 22. The specific number of photovoltaic trough bodies 2 and cover plates 23 is not limited in this article.

[0028] The core of the present invention is that by installing a plurality of photovoltaic trough bodies 2 on the side walls at both ends of the W-shaped water trough bracket 1, the photovoltaic trough bodies 2 are detachably installed on the W-shaped water trough bracket 1 and distributed along the W-shaped water trough bracket 1, thereby realizing the laying of the photovoltaic cable 3. In particular, by installing the cover plate 23 on the bracket 22, effective protection of the photovoltaic cable 3 is achieved.

[0029] In a specific embodiment, the mounting frame 21 has a "Z"-shaped structure, including a clamping portion 211, a connecting portion 212 and a fixing portion 213. The clamping portion 211, the connecting portion 212 and the fixing portion 213 are all thin plate structures. The clamping portion 211 and the fixing portion 213 are arranged in parallel. The connecting portion 212, the clamping portion 211 and the fixing portion 213 are installed at an acute angle to each other. The free end of the clamping portion 211 is provided with a hook, which is an L-shaped structure and is clamped in the notch of the W water guide trough bracket 1 through the hook; the fixing portion 213 is provided with a screw hole. During installation, the photovoltaic trough body 2 is locked and fixed to the W water guide trough bracket 1 and finally fixed to the purlin 4 by passing the self-tapping screw 5 through the screw hole. After fixing, the connecting portion 212 is completely fitted to the inclined surface of the W water guide trough bracket 1 to achieve the installation of the photovoltaic trough body 2.

[0030] Since the bracket 22 is arranged on the mounting frame 21, in order to improve the installation stability of the bracket 22, two connecting rods can be welded on the outer walls of the bracket 22 and the mounting frame 21, and the two connecting rods are used to connect the bracket 22 and the mounting frame 21; a connecting plate can also be welded on the outer walls of the bracket 22 and the mounting frame 21, and the weight of the bracket 22 and the photovoltaic cable 3 can be supported by the connecting plate to ensure the stability of the installation of the bracket 22.

[0031] In order to prevent the mounting frame 21 from being deformed, reinforcing ribs may be added between the clamping portion 211 and the connecting portion 212, and / or between the connecting portion 212 and the fixing portion 213. The reinforcing ribs may be welded to the mounting frame 21 or may be detachably installed by bolts, thereby improving the overall installation strength of the mounting frame 21 and extending the service life of the mounting frame 21.

[0032] In another embodiment, the photovoltaic trough body 2 can also be directly fastened to the inclined wall of the W-shaped water guide trough bracket 1 by using connecting parts such as bolts, so as to realize the detachable installation of the photovoltaic trough body 2.

[0033] In order to improve the installation strength of the photovoltaic trough body 2, the photovoltaic trough body 2 is preferably an integrated structure, and the various components constituting the photovoltaic trough body 2 are integrally processed or welded together to extend the service life of the photovoltaic trough body 2.

[0034] On the basis of the above embodiments, the bracket 22 and the cover plate 23 can be snap-fitted. Specifically, the outer wall of the open end of the bracket 22 is provided with a lower hook 221, and correspondingly, the outer wall of the open end of the cover plate 23 is provided with an upper hook 231. During installation, the upper hook 231 snaps into place with the lower hook 221, thereby fixing the cover plate 23 on the bracket 22 to prevent the cover plate 23 from being offset or falling due to external forces such as wind. Of course, bolts can also be used to fasten the two components. The connection method between the cover plate 23 and the bracket 22 can also be various, which is not limited in this article.

[0035] In addition, the bracket 22 is preferably an arc-shaped bracket 22 with an opening at the top, and the cover plate 23 is preferably an arc-shaped cover plate 23. The inner diameter of the outer edge of the cover plate 23 is slightly larger than the outer diameter of the open end of the bracket 22 to ensure that the cover plate 23 and the bracket 22 are tightly fitted.

[0036] In addition, the cover plate 23 and the bracket 22 are preferably made of stainless steel to prevent the cover plate 23 and the bracket 22 from rusting due to rainwater infiltration, improve the corrosion resistance of the cover plate 23 and the bracket 22, and extend the service life of the two components.

[0037] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
