Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology and provides a cable tray for photovoltaic applications. Background Technology

[0002] Cable trays are open metal or non-metal structures used to support, protect, and orderly lay cables. In photovoltaic power generation systems, cable trays play a crucial role, and their core function is also to support, protect, and orderly lay DC and AC cables specifically designed for photovoltaic systems.

[0003] Cables are prone to bending and folding when they turn. This is because the cable is stretched at the bend, and the turning radius is small. The bending and folding forces on the cable can cause damage and wear, which may eventually lead to cable breakage or short circuit. At the same time, after the cable is installed in the cable tray, the cable will become loose after long-term use. If the cable is too loose, it will cause the cable to hang at different heights, resulting in cable fluctuation and making it less safe and durable. Utility Model Content

[0004] To address at least one of the aforementioned technical shortcomings, this utility model provides a cable tray for photovoltaic applications, comprising a cable tray as the main body of the cable tray for photovoltaic applications. Positioning seats are fixedly mounted on both the left and right ends of the cable tray via connecting plates, and an mounting plate is fixedly mounted on the top of the cable tray. Adjusting plates are connected to both the front and rear ends of the top of the cable tray via adjusting screws. Cables are installed inside the positioning seats and adjusting plates.

[0005] Furthermore, the two positioning seats are symmetrically arranged and each has a compression bladder inside, and the inner wall of the compression bladder is lined with a pad.

[0006] Furthermore, tensioning sleeves are evenly distributed at the bottom of the adjusting plate, and the inner diameter of the tensioning sleeves is larger than the diameter of the cable.

[0007] Furthermore, both the compression bladder and the tensioning sleeve are hollow cylindrical in shape, and their inner diameters are the same.

[0008] Furthermore, the outer wall of the adjusting screw is threadedly connected to the inner wall of the cable tray, and the length of the adjusting screw is greater than the thickness of the cable tray.

[0009] Furthermore, the bottom end of the adjusting screw extends through to the bottom of the cable tray and is rotatably connected to the top of the cable tray.

[0010] Furthermore, the mounting plate is fixedly mounted on both the left and right ends of its bottom, and fixed plates that are connected to the top of the cable tray are also fixedly mounted on it. Bolt holes are also present at the four corners of the mounting plate.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] By setting up a positioning seat, a compression bladder, and a pad, the positioning seat can guide the direction of the cable after it passes through. The compression bladder inside the positioning seat is arc-shaped and has a large radius, which makes it less likely for the cable to be bent and damaged after passing through. The elasticity of the compression bladder can also hold the positioning cable and maintain the stability of the cable during equipment operation. In addition, the use of a pad can reduce the degree of wear between the cable and the inner wall, extend the service life of the cable, and prevent premature aging and breakage of the cable.

[0013] By setting up an adjusting screw, adjusting plate, and tensioning sleeve, the adjusting screw rotates, which drives the adjusting plate to move, thereby applying force to the tensioning sleeve. The inner wall of the tensioning sleeve contacts the cable, and under the action of force, it pushes the cable outward, thus keeping the cable in a stable tension state, preventing the cable from loosening, and making the cable tension distribution uniform. This ensures that the cable will not loosen during use, improving the reliability of the cable. Attached Figure Description

[0019] Please refer to Figures 1 to 4 ;

[0020] This embodiment provides a cable tray for photovoltaic applications. The cable tray 1 serves as a basic structure to provide support and stability. The mounting holes on the mounting plate 2 enable connection and assembly with other equipment and are fixed by bolts, screws, and other accessories, which can enhance the robustness and stability of the connection structure. The connecting plate 3 combines the positioning seat 5 with the cable tray 1 so that the cable 4 can be laid and installed on the cable tray.

[0021] like Figure 2 and 4 As shown, the positioning seat 5 can fix the position of the cable 4, prevent the cable 4 from swinging, and ensure stability; the compression bladder 6 can improve the stability of the cable 4; the pad 7 not only reduces the friction between the cable and the inner wall, but also plays a buffering role.

[0022] like Figure 2-3 As shown, the adjusting screw 8 can be controlled according to the length and tension of the cable 4, thereby ensuring that the cable 4 is in an appropriate tension state after installation; the movement of the adjusting plate 9 can be adjusted with the adjusting screw 8 according to the actual situation to adapt to cables 4 of different lengths and thicknesses; the tensioning sleeve 10 can also improve the stability of the cable 4.

[0023] like Figure 1-3 As shown, the outer wall of the adjusting screw 8 is threadedly connected to the inner wall of the cable tray 1. The length of the adjusting screw 8 is greater than the thickness of the cable tray 1, so that the adjusting screw 8 has a sufficient adjustment range. The bottom end of the adjusting screw 8 extends through to the bottom of the cable tray 1 and is rotatably connected to the top of the adjusting plate 9, so that the adjusting screw 8 can drive the adjusting plate 9 to move up and down after rotation.

[0024] Working principle: First, the cable tray 1 is assembled with other equipment through the mounting holes on the mounting plate 2. Then, the operator passes the cable 4 through the compression bladder 6 and tension sleeve 10 in the positioning seat 5. The pad 7 inside the compression bladder 6 can also reduce the wear between the cable 4 and the inner wall. Then, the operator rotates the two adjusting screws 8, which will drive the adjusting plate 9 to move, thereby applying force to the tension sleeve 10. The inner wall of the tension sleeve 10 contacts the cable 4, and under the action of force, the cable 4 is pushed outward, thereby keeping the cable 4 in a stable tension state, preventing the cable 4 from loosening, and ensuring that the cable 4 will not loosen during use.
