Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation auxiliary devices, specifically to a locking, shrinkable, earthquake-resistant photovoltaic cable tray. Background Technology

[0002] During the construction and installation of photovoltaic panels, it is necessary to ensure the stable power transmission of each photovoltaic panel. Therefore, cable trays need to be erected to ensure the stable arrangement of cables and transmit the electrical energy generated by the photovoltaic panels to achieve operations such as current return and inversion. At the same time, the cable trays also need to meet the requirements for the laying of communication cables to meet the signal and data transmission functions of auxiliary equipment or testing instruments installed at the photovoltaic panels.

[0003] Existing earthquake-resistant photovoltaic cable trays are typically installed by fitting them together. After installation, temperature changes and ground deformation can cause the cable trays to shrink, compress, or stretch, leading to damage and affecting their use. Furthermore, they cannot be rotated during installation to adapt to different installation sites. Therefore, it is necessary to solve the problem that existing earthquake-resistant photovoltaic cable trays suffer damage due to shrinkage, compression, or stretching caused by temperature changes and ground deformation after installation, and that they cannot be rotated to adapt to different installation sites. Utility Model Content

[0004] In view of the problems existing in the current locking and shrinking earthquake-resistant photovoltaic cable tray, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a locking and shrinking anti-seismic photovoltaic cable tray, which solves the problem that existing anti-seismic photovoltaic cable trays are damaged by shrinkage, compression or stretching caused by temperature changes and ground deformation after installation, and cannot be rotated to adapt to different installation sites.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A locking, shrinkable, earthquake-resistant photovoltaic cable tray includes a main support, a rotating connecting compartment, and a secondary support.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a locking, shrinking, earthquake-resistant photovoltaic cable tray.

[0026] This utility model provides, for example Figure 1-4 The locking, shrinkable, earthquake-resistant photovoltaic cable tray shown includes a main support 1, a rotating connecting chamber 2, and a secondary support 3. Rotating connecting chambers 2 are sleeved at both ends of the main support 1, and the secondary support 3 is sleeved at the other end of the rotating connecting chamber 2. The rotating connecting chamber 2 includes a rotating chamber 4, a rotating tube 5, a first connecting end 6, and a second connecting end 7. The rotating tube 5 is rotatably connected inside the cavity of the rotating chamber 4. The first connecting end 6 is rotatably connected to the other end of the rotating chamber 4, and the second connecting end 7 is fixedly connected to the other end of the rotating tube 5. An arc-shaped sliding opening 8 is provided on the side wall of the rotating chamber 4, and it is connected to the side wall of the rotating tube 5. The sliding connection has two hollow tubes, the first connecting end 6 and the second connecting end 7, and positioning plates 9 and return spring rods 10 are fixedly connected to both ends of the inner sidewall. Positioning ports 11 are provided on the sidewalls of both the auxiliary supports 3 and the main support 1. One end of each return spring rod 10 is inserted into the corresponding positioning port 11. The sidewall of the first connecting end 6 is inserted into the corresponding auxiliary support 3 via a fastening mechanism, and the sidewall of the second connecting end 7 is inserted into the corresponding main support 1 via a fastening mechanism. The rotating connecting chamber 2 facilitates rotation between the auxiliary supports 3 and the main support 1. The rotating tube 5, which is rotatably connected within the rotating chamber 4, allows for angle adjustment by sliding within the arc-shaped sliding opening 8. Rotation is achieved by the first connecting end 6, which is rotatably connected to the rotating chamber 4, making it suitable for use in different locations. Positioning plates 9, located at both ends of the sidewalls of the first and second connecting ends 6, are inserted into the main support 1 and secondary support 3 respectively for positioning during installation. Multiple reset spring rods 10 are inserted into corresponding positioning ports 11 in the main support 1 and secondary support 3 to provide anti-compression buffer protection during use, preventing deformation and twisting of the main support 1 and secondary support 3 due to temperature changes or terrain compression. The installation and fastening mechanism facilitates the fixed installation of the main support 1 with the rotating connecting chambers 2 at both ends, and the rotating connecting chambers 2 are fixedly connected to the secondary supports 3 at both ends. This solves the problem that existing earthquake-resistant photovoltaic cable trays, after installation, are susceptible to damage due to temperature changes and ground deformation caused by shrinkage, compression, or stretching, and cannot be rotated to adapt to different installation sites.

[0027] To facilitate the fixed connection between the rotating connecting chambers 2 at both ends and the auxiliary supports 3 and main supports 1 at both ends, such as... Figure 2-4 As shown, the installation and fastening mechanism includes a threaded port 12, a limiting screw 13, and a telescopic sliding port 14. Threaded ports 12 are provided on both side walls of the first connecting end 6 and the second connecting end 7, and the limiting screw 13 is threadedly connected to them. Telescopic sliding ports 14 are provided on both side walls of the auxiliary brackets 3 and the main bracket 1. The other end of each limiting screw 13 is slidably connected to the telescopic sliding port 14. The limiting screw 13, located in the threaded ports 12 on both side walls of the rotating connecting chamber 2, is inserted into the telescopic sliding ports 14 on both side walls of the auxiliary brackets 3 and the main bracket 1 for installation. The telescopic sliding port 14 allows the device to move when squeezed or pulled, preventing damage to the main bracket 1, the rotating connecting chamber 2, and the auxiliary bracket 3 from mutual squeezing or pulling.

[0028] To facilitate the placement of photovoltaic cables, such as Figure 1 and 2 As shown, rubber support columns 15 are fixedly connected inside the cavities of the two end auxiliary brackets 3 and the main bracket 1. A heat dissipation bracket 16 is fixedly connected to the top of each rubber support column 14. The heat dissipation bracket 16 set on the top of the rubber support column 15 facilitates the placement of photovoltaic cables and facilitates heat dissipation of the cables.

[0029] In order to perform maintenance on the cable ends of the auxiliary brackets 3 and the main bracket 1 at both ends, such as Figure 1 and 2 As shown, rotating seats 17 are fixedly connected to the side walls of the two auxiliary supports 3 and the main support 1. Each rotating seat 17 has a top cover plate 18 rotatably connected to its rod wall. Each top cover plate 18 has a pin 19 fixedly connected to its side wall. Sockets 20 are fixedly connected to the side walls of the two auxiliary supports 3 and the main support 1. The other end of each pin 19 is inserted into the corresponding socket 20. The top cover plate 18, which is rotatably connected in the rotating seat 17, can be opened by rotation, thus facilitating the maintenance of the cable ends in the two auxiliary supports 3 and the main support 1. The pin 19 is inserted into the socket 20 after the top cover plate 18 is closed by rotation, thereby limiting the rotation of the top cover plate 18.

[0030] To increase the service life of the main support 1, the rotating connecting compartment 2, and the auxiliary support 3, such as Figure 1-4 As shown, the surfaces of the main support 1, the rotating connecting chamber 2, and the auxiliary support 3 are all coated with galvanized steel, which increases the service life of the main support 1, the rotating connecting chamber 2, and the auxiliary support 3.

[0031] To provide support and cushioning for the main support 1, rotating connecting chamber 2, and auxiliary support 3, such as Figure 1 and 2As shown, U-shaped support plates 21 are fixedly connected to both ends of the side walls of the sub-supports 3 at both ends. Shock absorbers 22 are fixedly connected between the top of the U-shaped support plates 21 and the bottom of the sub-supports 3. By using the U-shaped support plates 21 and the shock absorbers 22, the main support 1, the rotating connecting chamber 2 and the sub-supports 3 are supported and buffered for shock absorption.

[0032] How to use:

[0033] In use, the two rotating connecting chambers 2 are inserted into the two ends of the main bracket 1. After insertion, the limiting screws 13 in the threaded openings 12 on both sides of the rotating connecting chamber 2 are inserted into the telescopic sliding openings 14 on both sides of the main bracket 1, thus completing the installation between the two rotating connecting chambers 2 and the main bracket 1. Then, the other end of the two rotating connecting chambers 2 is inserted into the corresponding auxiliary bracket 3. After insertion, the limiting screws 13 in the threaded openings 12 on both sides of the other end of the rotating connecting chamber 2 are inserted into the telescopic sliding openings 14 on both sides of the auxiliary bracket 3, thus completing the installation between the two rotating connecting chambers 2 and the auxiliary bracket 3. The installation is carried out in a certain way. According to the installation terrain, the rotating tube 5, which is set in the rotating chamber 4 and rotated, is used to adjust the angle by sliding in the arc-shaped sliding mouth 8. The rotation is achieved by cooperating with the first connecting end 6, which is rotatably connected to the rotating chamber 4, so that it can be used in different sites. Finally, one end of the photovoltaic cable is inserted into the sub-support 3, the rotating connecting chamber 2, and the main support 1 in sequence, and then through the other rotating connecting chamber 2 and the sub-support 3. After rotating and closing the top cover 18, it is connected to the socket 20 through the pin 19, thereby limiting the rotation of the top cover 18.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
