Description

Technical Field

[0001] This utility model relates to the field of cable trays, and in particular to a cable tray for photovoltaic energy storage cabinets. Background Technology

[0002] Currently, Chinese utility model patent CN222148023U discloses a cable tray for energy storage cabinets. While the addition of a cover plate improves front protection and cable guidance, other problems exist during use. For example, it lacks a cable distribution and positioning function; cables are directly placed inside the rack during use, making them prone to tangling due to movement and collisions, resulting in poor safety. Furthermore, it hinders internal maintenance. The front cover plate needs to be installed during use, but since the cable tray is vertically installed inside the cabinet, the sliding connection of the cover plate can fall off. While screw fixing is secure, tools are needed for disassembly and assembly. To address these problems, we propose a cable tray for photovoltaic energy storage cabinets. Utility Model Content

[0003] The purpose of this utility model is to provide a cable tray for photovoltaic energy storage cabinets, which solves the problems that existing cable trays do not have branching and positioning functions and are inconvenient for internal maintenance.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable tray for a photovoltaic energy storage cabinet, including a base frame, two positioning seats installed inside the base frame, a positioning plate provided on the front of the positioning seat, a wire placement groove opened inside the positioning seat, threaded rods symmetrically welded on the front of the positioning seat, the other end of the threaded rods passing through to the outside of the positioning plate and threadedly connected to a nut, a cover plate provided on the front of the base frame, a fixing frame bolted to the back of the cover plate, two connecting blocks slidably arranged inside the fixing frame, a limit pin installed on one side of the connecting block, limit holes opened on both sides of the base frame, and a limit spring bolted between the other side of the connecting block and the fixing frame through a spring fixing plate.

[0005] The above technical solution can provide cable positioning function, improve the cable's tensile strength, avoid cable entanglement and collision, ensure high safety, facilitate internal maintenance, and is simple and convenient to operate, thereby improving personnel's work efficiency, stability and flexibility.

[0006] The present invention is further configured such that a spring washer is slidably fitted onto the surface of the threaded rod.

[0007] By adopting the above technical solution and setting the spring washer, the fixing effect of the nut after tightening can be improved, which can play a role in shock prevention and loosening prevention.

[0008] The present invention is further provided that: a protective pad is adhered to the back of the positioning plate, and the protective pad is made of rubber material.

[0009] By adopting the above technical solution, the cable sheath can be protected by the protective pad, preventing damage to the sheath when the positioning plate moves backward and squeezes the cable.

[0010] The present invention is further configured such that the surfaces of the base frame and the cover plate are coated with anti-corrosion coating.

[0011] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects of the base frame and cover plate surface can be improved.

[0012] The present invention is further configured such that: a fixing rod is installed on the front side of the connecting block, two sliding grooves are opened on the front side of the cover plate, and the other end of the fixing rod extends to the outside of the sliding groove.

[0013] By adopting the above technical solution, the setting of the fixed rod and the sliding groove makes it easy for personnel to pull the two connecting blocks inward.

[0014] The present invention is further configured such that the limiting spring is made of carbon spring steel.

[0015] Using the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good resistance to spring reduction, low temperature resistance and corrosion resistance.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model first installs the base frame onto the inner wall of the energy storage cabinet with screws. After the base frame is installed, the cable is straightened and placed in the cable slot in the positioning seat. After all the cables are placed in, the positioning plate is lifted and put onto the threaded rod. Then, the positioning plate is pushed inward to clamp the cable. Finally, the spring washer and nut are turned into the threaded rod in sequence and tightened. It can have the function of cable positioning, improve the cable's tensile strength, avoid cable entanglement and collision, and has high safety.

[0018] 2. This utility model allows users to grasp two fixing rods with both hands and push them inward. As the fixing rods are pushed, they cause the connecting block and the limiting pin to move inward. When the connecting block moves inward, it compresses the limiting spring, causing it to contract and deform. After the fixing rods are pushed all the way down, the cover plate is lifted and aligned with the front of the base frame. Finally, the fixing rods are released to allow the connecting block to return to its original position. When the connecting block returns to its original position, it causes the limiting pin to insert into the limiting hole inside the base frame. This facilitates internal maintenance, is simple and convenient to operate, improves the work efficiency of personnel, and provides good stability and flexibility. Attached Figure Description
