[0002] In the laying and operation of power systems, cable trays, as the core supporting facilities for cable laying, play an important role in protecting cables, organizing line routes, and ensuring the safety of power transmission. From the laying of high-voltage cables in urban underground utility tunnels to the arrangement of power cables in industrial park factories, from the separation of strong and weak current lines in high-rise buildings to the centralized management of cables in substations, cable trays play an indispensable role. For example, in urban power grid renovation projects, cable trays need to neatly store multiple sets of cables of different specifications to avoid the risk of short circuits caused by messy and crossed lines; in the power supply system of production lines in large factories, cable trays need to provide stable support for cables to ensure that equipment continuously receives power and ensures continuous production operation.

[0003] Traditional cable trays rely on a large number of bolts for assembly. When it is necessary to inspect the inside of the cable tray, the staff needs to remove the bolts on the top of the cable tray in order to remove the top cover. However, when inspecting a large number of cables inside the cable tray one by one, the amount of work involved in removing the bolts is large. It is also difficult to remove the cover of some enclosed cable trays. Checking the operating status of the cables takes a lot of time and affects the efficiency of troubleshooting.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing cable tray structures used for power line laying. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example 1: Please refer to Figure 1 - Figure 4 This embodiment of a cable tray structure for power laying includes a cable tray body 1 and a cover plate 2. The bottom of the cable tray body 1 is fixedly connected to a suspension bracket 3. One end of the cover plate 2 is hinged to the top of the cable tray body 1. The inside of the cable tray body 1 is provided with a first partition plate 5 and a second partition plate 6. The top of the other end of the cover plate 2 is machined with a groove 4. The bottom of the other end of the cover plate 2 is fixedly connected to a locking block 9. Two balls 10 are provided at both ends of the locking block 9. Two grooves 11 are machined on the inner walls of both sides of the cable tray body 1. The balls 10 are snapped into the inside of the grooves 11. One end of the balls 10 is provided with a movable block 12. A return spring 14 is provided on one side of the movable block 12.

[0022] The cable tray body 1 is suspended on the top of the wall by the suspension bracket 3. When it is necessary to inspect the cables inside the cable tray body 1, the cover plate 2 is opened and the pull groove 4 is pulled, so that the pull groove 4 drives one end of the cover plate 2 to move upward. The ball 10 will be squeezed into the interior of the locking block 9, thereby opening the cover plate 2. By setting multiple cover plates 2, it is convenient to carry out segmented and fixed-point inspections and avoid large-scale dismantling of the top of the cable tray body 1.

[0023] Furthermore, the inner wall of the cable tray body 1 is machined with a plurality of first sliding grooves 7, and the two sides of the first partition plate 5 are movably connected to the inside of the first sliding grooves 7. The inner wall of the cable tray body 1 is machined with a plurality of second sliding grooves 8, and the two sides of the second partition plate 6 are movably connected to the inside of the second sliding grooves 8.

[0024] The first partition plate 5 and the second partition plate 6 are located inside the cable tray body 1 and are used to separate the cables. The baffles on both sides of the second partition plate 6 are located in the middle of the vertical plate and can separate the cables vertically. The baffles on both sides of the first partition plate 5 are located at the top of the vertical plate and can compact and limit the cables inside the cable tray body 1 to prevent movement. The first partition plate 5 or the second partition plate 6 can be selected according to the number and size of the cables inside the cable tray body 1.

[0025] Furthermore, the locking block 9 has two rolling grooves 15 machined at both ends, and the ball 10 is movably connected inside the rolling groove 15. One end of the rolling groove 15 is machined with a movable groove 16, and the movable block 12 is movably connected inside the movable groove 16. When the cover plate 2 is closed, the cover plate 2 will drive the locking block 9 downward, and the ball 10 will contact the inner walls on both sides of the bridge body 1, thereby squeezing the ball 10 and causing the ball 10 to move along the inside of the rolling groove 15. The movement of the ball 10 will squeeze the movable block 12, and the movable block 12 will compress the return spring 14.

[0026] Furthermore, one end of the return spring 14 is fixedly connected to one side of the movable block 12, and the other end of the return spring 14 is fixedly connected to the inner wall of one end of the movable groove 16. With the return spring 14 provided, when the ball 10 is squeezed, the ball 10 will drive the return spring 14 to compress. When the ball 10 moves to one side of the groove 11, the guide rod 13 returns to its original position and extends. The guide rod 13 will drive the movable block 12 to move, so that the ball 10 is inserted into the inside of the groove 11. The cover plate 2 is fixed by the elastic force of the spring, which makes it easy for the staff to open the cover plate 2 and seal the top of the cable tray body 1, avoiding the need to remove a large number of bolts to open the inside of the cable tray body 1.

[0027] Furthermore, a guide rod 13 is fixedly connected to one side of the movable block 12. The guide rod 13 is located inside the return spring 14. A connecting groove 17 is machined at one end of the movable groove 16. The guide rod 13 is movably connected inside the connecting groove 17. By providing the guide rod 13, the guide rod 13 moves along the inside of the connecting groove 17, thereby limiting the movement of the movable block 12. At the same time, the guide rod 13 restricts the radial displacement of the spring during the extension and contraction process, avoiding stress concentration caused by skewness.

[0028] Working principle: When it is necessary to inspect the cables inside the cable tray body 1, when the cover plate 2 is opened, the pull groove 4 is pulled, which causes the pull groove 4 to move one end of the cover plate 2 upward. The ball 10 will be squeezed into the interior of the locking block 9, thereby opening the cover plate 2. By setting multiple cover plates 2, it is convenient to carry out segmented and fixed-point inspections, avoiding large-scale dismantling of the top of the cable tray body 1.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
