Description

Technical Field

[0001] This utility model relates to the field of cable trays, specifically a cable tray for photovoltaic power generation. Background Technology

[0002] Cable trays are divided into trough type, tray type, ladder type, and mesh type structures. They are composed of supports, brackets and installation accessories. Cable trays inside buildings can be erected independently or laid on various buildings and pipe rack supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors in buildings.

[0003] Currently, photovoltaic power generation equipment requires multiple cables for power transmission during operation. Due to the large number of cables, cable trays are needed for support and cable arrangement. In existing technologies, such as patent number CN2019217181638, a new type of cable tray for photovoltaic power generation is disclosed. Although this cable tray arranges the cables, it relies on ventilation holes for natural air cooling of the cables. However, this reduces the efficiency of natural air cooling of the cables in hot weather. Moreover, the cable tray is fixed to the upper and lower sections with multiple bolts, which requires users to remove the bolts when replacing cables, thus reducing the efficiency of cable replacement.

[0014] (III) Beneficial Effects

[0015] This utility model provides a cable tray for photovoltaic power generation. It has the following beneficial effects:

[0016] 1. This cable tray for photovoltaic power generation, through its fixed-line mechanism, first controls the servo motor to rotate forward. The forward rotation of the servo motor drives the adjusting shaft to rotate forward, which in turn moves the upper bridge platform downward. The downward movement of the upper bridge platform moves the upper fixing groove and the upper protective pad downward simultaneously. When the groove surface of the upper protective pad is in full contact with the surface of the cable, the cable is quickly clamped and fixed. This fixing method greatly reduces the labor intensity of the workers. Then, the servo motor is controlled to rotate in reverse. The reverse rotation of the servo motor drives the adjusting shaft to rotate in reverse, which in turn moves the upper protective pad upward. When the upper protective pad is fully separated from the surface of the cable, the photovoltaic power generation cable can be easily disassembled, making it convenient for workers to quickly replace the new cable, thus greatly improving the practicality of the cable tray.

[0017] 2. This cable tray for photovoltaic power generation, through its heat dissipation mechanism, first controls the start of the air pump. Once the air pump starts, it drives the upper and lower guide holes to transfer the heat from the surface of the cable to the interior of the upper and lower bridge platforms, respectively. Then, the air pipe exhausts the heat through the exhaust port of the air pump. This quickly completes the heat dissipation of the upper and lower surfaces of the cable, thereby effectively improving the service life of the cables used for photovoltaic power generation. At the same time, it also makes the cable tray more convenient to use. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] This utility model embodiment provides a cable tray for photovoltaic power generation, such as... Figure 1-9 As shown, the assembly includes a cable tray plate 1, a cable fixing mechanism 2, a lower support plate 3, a limiting sleeve 4, an assembly frame 5, a heat dissipation mechanism 6, an assembly hole 7, and a positioning post 8. The bottom of the cable fixing mechanism 2 is fixedly connected to the bottom surface of the inner cavity of the cable tray plate 1. The tops of the two lower support plates 3 are fixedly connected to the bottom surfaces of the front and rear ends of the cable tray plate 1, respectively. The inner cavities of the two limiting sleeves 4 are movably fitted onto the outside of the bottom ends of the two lower support plates 3. The top surfaces of the middle sections of the two assembly frames 5 are fixedly connected to the bottoms of the two limiting sleeves 4. The two assembly frames 5 are both U-shaped, and through holes are opened on the top surfaces of both ends of the two assembly frames 5. The top of the heat dissipation mechanism 6 is fixedly connected to the bottom surface of the rear end of the cable tray plate 1. The assembly holes 7 are respectively opened on the front and back of the front limiting sleeve 4 and the lower support plate 3. The rear end of the positioning post 8 is inserted into the inner cavity of the assembly hole 7.

[0030] The cable fixing mechanism 2 includes a lower bridge platform 201, a lower fixing groove 202, a lower protective pad 203, a lower fixing plate 204, a limiting post 205, a displacement block 206, an upper bridge platform 207, an upper fixing groove 208, an upper protective pad 209, an adjustment hole 210, an adjustment shaft 211, and a servo motor 212. The bottom of the lower bridge platform 201 is fixedly connected to the bottom surface of the inner cavity of the cable tray plate 1, and the lower fixing grooves 202 are respectively opened on the top surface of the lower bridge platform 201. The bottom surface of the lower protective pad 203 is bonded to the groove surface of the lower fixing groove 202. The rear end of the lower fixing plate 204 is fixedly connected to the middle of the front of the lower bridge abutment 201. The bottom end of the limiting post 205 is fixedly connected to the top surface of the lower fixing plate 204. The inner cavity of the displacement block 206 is movably sleeved on the outer wall of the top of the limiting post 205. The middle of the front of the upper bridge abutment 207 is fixedly connected to the rear end of the displacement block 206. The upper fixing grooves 208 are respectively opened on the upper bridge abutment 207. The bottom surface of the bridge platform 207 and the top surface of the upper protective pad 209 are respectively bonded to the groove surface of the upper fixing groove 208. The adjustment hole 210 is opened in the middle of the top and bottom surfaces of the upper bridge platform 207. The bottom end of the adjustment shaft 211 is inserted into the inner cavity of the adjustment hole 210. The bottom of the servo motor 212 is fixedly connected to the middle of the bottom surface of the inner cavity of the lower bridge platform 201, and the end of the output shaft at the top of the servo motor 212 is fixedly connected to the bottom end of the adjustment shaft 211. Controlling the servo motor 212 to rotate forward will drive the adjustment shaft 211 to rotate forward. The rotation of the adjustment shaft 211 will drive the upper bridge platform 207 to move downward. The downward movement of the upper bridge platform 207 will drive the upper fixing groove 208 and the upper protective pad 209 to move downward simultaneously. When the groove surface of the upper protective pad 209 is in full contact with the surface of the cable, the clamping and fixing of the cable is quickly completed.

[0031] In use, first, multiple cables are placed into the lower fixing groove 202. Then, the servo motor 212 is controlled to rotate forward, which drives the adjusting shaft 211 to rotate forward. The adjusting shaft 211 then moves the upper bridge platform 207 downward. The downward movement of the upper bridge platform 207 moves the upper fixing groove 208 and the upper protective pad 209 downward simultaneously. When the groove surface of the upper protective pad 209 is in full contact with the surface of the cable, the cable clamping and fixing are quickly completed. Then, the lower support plate 3 is inserted into the limiting sleeve 4. Then, the positioning pin 8 is controlled to rotate forward, which moves its rear end backward. When the positioning pin 8 is fully moved into the inner cavity of the assembly hole 7, the cable tray structure is fixed in one step. Then, the two assembly brackets 5 are installed in the use position with bolts. For heat dissipation, the air pump 604 is started first. The start of the air pump 604 drives the upper guide hole 602 and the lower guide hole 601 to dissipate heat from the surface of the cable. The heat is transferred to the interior of the upper bridge platform 207 and the lower bridge platform 201, and then the heat is discharged through the exhaust port of the air pump 604 by the air extraction pipe 605. This quickly completes the heat dissipation of the upper and lower surfaces of the cable, thereby effectively improving the service life of the photovoltaic power generation cable. When disassembling the cable, first control the servo motor 212 to reverse. The reverse rotation of the servo motor 212 can drive the adjustment shaft 211 to reverse. The reverse rotation of the adjustment shaft 211 can drive the upper protective pad 209 to move upward. When the upper protective pad 209 is fully separated from the surface of the cable, the photovoltaic power generation cable can be easily disassembled, which makes it convenient for the staff to quickly replace the new cable. When disassembling the cable tray, first control the positioning column 8 to reverse. The reverse rotation of the positioning column 8 can disengage from the assembly hole 7. At this time, the staff lifts the lower bridge platform 201 upward. The upward movement of the lower bridge platform 201 can drive the lower support plate 3 to disengage from the limit sleeve 4. At this time, the disassembly of the entire cable tray structure can be quickly completed, which facilitates the secondary installation of the cable tray structure.

[0032] Furthermore, the heat dissipation mechanism 6 includes a lower guide hole 601, an upper guide hole 602, a connecting pipe 603, an air pump 604, and an air extraction pipe 605. The lower guide holes 601 are respectively opened in the middle of the groove surface of the lower fixed groove 202, and the upper guide holes 602 are respectively opened in the middle of the bottom surface of the upper protective pad 209 and the upper fixed groove 208. The top and bottom ends of the connecting pipe 603 are respectively connected to the back of the upper bridge platform 207 and the lower bridge platform 201. The top of the air pump 604 is fixedly connected to the bottom surface of the rear end of the bridge plate 1, and the air pump 604 is controlled to start. When the air pump 604 starts, it drives the upper guide hole 602 and lower guide hole 601 to transfer the heat from the surface of the cable to the interior of the upper bridge platform 207 and lower bridge platform 201, respectively. Then, the air extraction pipe 605 discharges the heat through the exhaust port of the air pump 604. This quickly completes the heat dissipation of the upper and lower surfaces of the cable, thereby effectively improving the service life of the photovoltaic power generation cable. The top and bottom ends of the air extraction pipe 605 are connected to the middle section of the outer wall of the connecting pipe 603 and the air extraction port at the rear end of the air pump 604, respectively. Figure 1 As shown.

[0033] Furthermore, both assembly racks 5 are U-shaped, and both ends of the top surface of the assembly racks 5 have through holes, such as... Figure 1 As shown, the through holes allow the cable tray to be secured to its intended position using bolts.

[0034] Furthermore, the surface of the rear end of the positioning post 8 is threaded to the inner wall of the assembly hole 7. The lower fixing groove 202 is U-shaped, while the upper fixing groove 208 is arc-shaped, such as... Figure 7 and Figure 8 As shown, the cooperation between the lower fixing groove 202 and the upper fixing groove 208 can effectively fix the cable.

[0035] Furthermore, the surface of the adjusting shaft 211 is threadedly connected to the inner wall of the adjusting hole 210, such as... Figure 7 As shown.

[0036] Furthermore, the connector 603 is a flexible hose, such as... Figure 5 As shown, the hose can accommodate the up-and-down movement of the upper bridge platform 207.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
