Description

Technical Field

[0001] This utility model belongs to the technical field of cable protection devices, and relates to a multi-layer waterproof cable protection trough. Background Technology

[0002] In onshore and offshore new energy photovoltaic power generation bases, the power collection lines in the power plant serve as a transmission medium for collecting power from the power source, effectively transmitting the power generated by each component to the step-up substation. The cables need to be in a energized working state, and the cable protection troughs can not only protect the safety of the cables themselves during operation, but also protect other objects from electric shock.

[0003] In current engineering projects, cable installation typically employs three methods: shallow burial of bare cables underground, installation in ordinary surface cable trays, and underwater waterproof cable installation. Shallow burial of bare cables results in concealed underground cables after the surface is restored, making them difficult to inspect during maintenance and repair. Furthermore, buried cables are susceptible to corrosive elements and water erosion. Existing surface cable trays are ill-suited to varying terrain, often employing snap-fit ​​structures for cable fixation, resulting in complex structures, poor installation flexibility and adaptability, cumbersome maintenance processes, low efficiency, and low space utilization as each tray can only accommodate one cable. Underwater waterproof cable installation utilizes specialized cables with stringent waterproofing requirements, presenting significant construction challenges, high costs, and complex and difficult fault repair.

[0004] To ensure the safety of the power collection line cable itself, extend its service life, and ensure reliable power transmission, it is necessary to provide better all-round protection for the cable, strengthening its own protection and protection against other objects. Utility Model Content

[0006] The technical solution adopted by this utility model is a multi-layer waterproof cable protection trough box, including an adjustable base A, a protective device B installed on the top of the adjustable base A, the protective device B including a C-shaped protective trough frame and a side sealing plate, the C-shaped protective trough frame and the side sealing plate form a four-sided enclosed structure, multiple layers of hooks are fixed on the inner wall of the C-shaped protective trough frame opposite to the side sealing plate, the distance between two adjacent layers of hooks is greater than the maximum diameter of the cable, the top surface of the C-shaped protective trough frame is provided with heat dissipation holes, the bottom surface is provided with drainage holes, and the top surface of the C-shaped protective trough frame is a streamlined arched structure.

[0007] The adjustable base A includes an N-shaped bracket and two L-shaped bases. The two L-shaped bases are located on the left and right sides of the N-shaped bracket, respectively, and are connected and fixed to the N-shaped bracket by a second adjusting fixing bolt and a second adjusting fixing nut. The L-shaped bases have strip bolt holes on their sides, and the N-shaped brackets have long slot bolt holes on both sides. The second adjusting fixing bolt passes through the long slot bolt holes and the strip bolt holes and is threadedly connected to the second adjusting fixing nut.

[0008] The C-type protective groove frame and the N-type bracket are connected and fixed by the third adjusting fixing bolt and the third adjusting fixing nut.

The third adjusting and fixing bolt passes through the elongated bolt holes B and A and is threadedly connected to the third adjusting and fixing nut.

[0010] The L-shaped base has a first fixing bolt hole on its bottom surface. The first fixing bolt hole is elongated and a first anchor bolt is installed inside the first fixing bolt hole.

[0011] The C-type protective slot frame has a lower mounting slot at the bottom of the side opening and an upper mounting slot at the top, with the side sealing plate located between the lower and upper mounting slots.

[0012] The side opening of the C-type protective slot frame is larger than the height of the side sealing plate, the height of the side sealing plate is larger than the vertical opening distance between the lower and upper mounting slots, and the depth of the upper mounting slot is greater than the depth of the lower mounting slot.

[0018] (2) The adjustable base enables the cable protection trough to be adjusted in three dimensions: longitudinal, transverse and vertical, to adapt to the relocation correction of cable installation under different curve radii and base undulation conditions, making on-site construction more flexible and convenient.

The hook is integrally formed with the C-shaped protective trough frame, avoiding temporary processing and assembly on site. The interface quality is guaranteed, simplifying the installation and dismantling process, reducing the workload, and improving the installation and dismantling speed and efficiency.

[0023] (7) The side sealing plate is made of transparent material, which allows for visual observation of the cables in the C-type protective trough. During installation and maintenance, the cables are clearly visible in case of fault or damage. The side sealing plate is easy to install and remove, easy to operate, has multiple functions and low cost.

[0024] (8) The overall structure of this utility model is simple, can be manufactured in one piece, and can be directly assembled on site. It is convenient and quick to implement and maintain. It can stabilize and protect the cable, and further ensure the safety and quality of power transmission. Attached Figure Description

The protective device B includes a C-shaped protective trough frame 19 and side sealing plates 13. The side sealing plates 13 can be inserted and removed in sections along the cross-section of the C-shaped protective trough frame 19 or pushed in and out by floating up and down along the longitudinal opening of the C-shaped protective trough frame 19. The C-shaped protective trough frame is made of metal or non-metal materials (such as stainless steel plates or plastic plates) with reliable strength, rigidity, load-bearing capacity, and certain strain performance. It serves to protect against strong winds, rain and snow, high-temperature radiation, low-temperature frost heave, and other loads and special loads under working conditions. It can withstand external loads of 10KN / m or other external loads such as trampling. The C-shaped protective trough frame 19 and the side sealing plates 13 form a four-sided enclosed structure, which can not only fully enclose and protect the cable, but also prevent the harm of electric shock from animals or other organisms, and extend the service life of the cable.

[0034] Two layers of hooks 20 are fixed on the inner wall of the C-shaped protective trough 19 opposite to the side sealing plate 13. The distance between the two adjacent layers of hooks is greater than the maximum diameter of the cable, which facilitates the installation and removal of the cable and realizes the cable's resting installation and fixation. The top surface of the C-shaped protective trough 19 is provided with heat dissipation holes 15 to achieve timely heat dissipation. The size and shape of the holes can be adjusted according to the requirements. The bottom surface of the C-shaped protective trough 19 is provided with drainage holes 17.
