Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a cable tray for photovoltaic power stations that facilitates wiring. Background Technology

[0002] Cable trays are metal or non-metal structures used to support, fix, and protect cables. They are widely used in construction, industry, power, communications, and other fields, providing a safe and orderly laying path for cables.

[0003] Nowadays, the cables in photovoltaic power stations need to withstand external forces such as wind loads, snow loads, and seismic loads. To extend the service life of the cables, workers use cable trays to suspend them, avoiding direct contact with the ground or equipment and reducing insulation damage caused by friction, compression, or animal chewing. Most photovoltaic power stations use trough-type cable trays, which have a U-shaped structure. When in use, the cables are placed horizontally inside the cable tray, and the top opening is sealed with a cover plate.

[0004] However, to ensure good heat dissipation for cables within the cable tray, the inner space of a trough-type cable tray is usually relatively large. Because of this, if the cables are not secured after being placed inside the tray, their arrangement may become disordered, such as becoming tangled. This not only exacerbates cable overheating but may also affect the installation of cables in other locations later. Therefore, we propose a photovoltaic power station cable tray that facilitates wiring and effectively solves these problems. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic power station cable tray that facilitates wiring, thereby solving the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a photovoltaic power station cable tray that facilitates wiring, including a frame, the frame being U-shaped, and two slotted clips slidingly disposed on the inner side of the frame along its own height direction, the two slotted clips being located near the openings on both sides of the frame, the slotted clips being used to fix cables.

[0007] Optionally, the card slots are distributed along the width of the frame, and the bottom surface of the card slots is provided with a plurality of card slots, which are arranged at equal intervals along the width of the frame.

[0008] Optionally, two sliding grooves are provided on each of the two side plates of the frame, and the four sliding grooves are respectively opposite to the left and right sides of the two card slots. The sliding grooves are used to slide and cooperate with the card slots.

[0009] Optionally, the left and right sides of the card slot are fixedly provided with sliding rods. The sliding rods are slidably connected in the sliding groove along the height direction of the frame. The end of the sliding rod away from the card slot extends out of the outside of the frame and is fixedly provided with a connecting rod. The connecting rods are distributed vertically, and the top ends of the two connecting rods extend to the top of the frame and are connected to a pressure plate together.

[0010] Optionally, the slot may be arc-shaped, inverted U-shaped, or inverted V-shaped.

[0011] Optionally, the card slot is U-shaped, and a limiting block is slidably provided on the inner side of the card slot along its own length direction. The limiting block and the card slot are detachably connected, and a limiting groove is provided at the bottom of the limiting block.

[0023] 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.

[0024] Example 1: Please refer to Figure 1 - Figure 6 A photovoltaic power station cable tray that facilitates wiring includes a frame 1, which is U-shaped and consists of a base plate and two side plates. The top surface and the front and rear sides of the frame 1 are open, and the base plate of the frame 1 has several heat dissipation holes to improve the heat dissipation effect on the cables.

[0025] Furthermore, two clips 2 are slidably provided on the inner side of the frame 1 along its own height direction. The two clips 2 are located near the openings on both sides of the frame 1. The clips 2 are used to fix the cable so that when the cable passes through the inner side of the frame 1, the area of ​​the cable near the openings on both sides of the frame 1 can be pressed against the bottom wall of the frame 1 by the clips 2, thus limiting the cable.

[0026] Specifically, the cable trays 2 are distributed along the width of the frame 1. The bottom surface of the cable trays 2 has several slots 201. Therefore, when the cable trays 2 move downward, they can limit the cables within the slots 201, so that there is a certain gap between the cables, making the overall layout more aesthetically pleasing and avoiding cable tangling that increases heat dissipation.

[0027] More optimized, the shape of the slot 201 is arc-shaped, inverted U-shaped, or inverted V-shaped, so that the slot 201 can not only limit the cable by applying downward pressure to the cable, but also cooperate with the bottom wall of the frame 1 to frame the cable inside, thus limiting the cable as well, and can accommodate more specifications of cables.

[0028] Specifically, two sliding grooves 101 are provided on each of the two side plates of the frame 1. The four sliding grooves 101 are respectively opposite to the left and right sides of the two card slots 2. The left and right sides of the card slots 2 are slidably connected to the frame 1. That is, the sliding grooves 101 are used to allow the card slots 2 to be slidably connected to the frame 1.

[0029] Each of the left and right sides of the card slot 2 is fixedly equipped with a sliding rod 3, which is slidably connected to the slide groove 101 along the height direction of the frame 1. The width of the card slot 2 is greater than the width of the slide groove 101 to prevent the card slot 2 from moving outside the frame 1 through the slide groove 101. The width of the sliding rod 3 is equal to the width of the slide groove 101. The left and right sidewalls of the sliding rod 3 are slidably connected to the inner sidewall of the slide groove 101, and the frictional resistance between the left and right sidewalls of the sliding rod 3 and the inner sidewall of the slide groove 101 is relatively large. Specifically, in this embodiment, when the operator applies a force greater than 10N to the card slot 2, the sliding rod 3 can be pushed to slide up and down within the slide groove 101.

[0030] Furthermore, the end of the slide bar 3 away from the card slot 2 extends out of the outside of the frame 1 and is fixedly provided with a connecting rod 301. The connecting rod 301 is distributed vertically, and the tops of the two connecting rods 301 extend to the top of the frame 1 and are connected to the pressure plate 302 together, so that the staff can control the card slot 2 to move up and down through the pressure plate 302, which is convenient for the staff to operate.

[0031] In this embodiment, a cover plate 4 is also slidably fitted on the top of the frame 1 along its own length direction. The cover plate 4 and the pressure plate 302 are connected by bolts so that both the cover plate 4 and the card slot 2 can be fixed.

[0032] Example 2: Please refer to Figure 7 This application also proposes another embodiment, which differs from Embodiment 1 in that the card slot 2 is U-shaped, and a limiting block 202 is slidably provided on the inner side of the card slot 2 along its own length direction, so that the distance between the limiting blocks 202 can be adjusted. Furthermore, the limiting blocks 202 and the card slot 2 are detachably connected, and a limiting groove 203 is provided at the bottom of the limiting blocks 202, so that workers can replace the limiting blocks 202.

[0033] Specifically, the top wall of the cable tray 2 has several sliders that slide along its length. The limiting block 202 is located at the bottom of the top wall of the cable tray 2. The sliders and the limiting block 202 are detachably connected by bolts. Similarly, the limiting groove 203 is arc-shaped, inverted U-shaped, or inverted V-shaped. Therefore, the staff can select different limiting blocks 202 for installation according to different cable specifications, and can also adjust the distance between each limiting block 202 to accommodate more cable specifications.

[0034] Application scenarios and operation procedures of this utility model: In photovoltaic power stations, cables need to be installed at a certain height above the ground to avoid moisture, insect damage, and friction with the ground, thereby extending the service life of the cables. This is where cable trays are needed.

[0035] In use, first install the frame 1 to a suitable height according to the site conditions; then, several cables can be passed through the inside of the frame 1, and the height of the cable tray 2 can be adjusted by pushing and pulling the pressure plate 302 up and down, so that several cables and several slots 201 correspond one by one. Finally, the cable tray 2 is used to press the cable onto the inner bottom wall of the frame 1; at this time, the cover plate 4 can be closed on the top of the frame 1; finally, the pressure plate 302 and the cover plate 4 are fixed with bolts, so that the cable tray 2 and the cover plate 4 are fixed at the same time, realizing the protection of the cable and the wiring operation.
