Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power station installation, specifically a photovoltaic AC cable laying device. Background Technology

[0002] In photovoltaic power station cable construction, cable laying devices are generally used, such as the universal cable laying device disclosed in Chinese patent CN108313811B. However, for long-distance cable laying, this requires repeated operations, consuming a lot of time and manpower, resulting in slow construction progress. Moreover, during manual cable laying, the cable frequently rubs against the ground or other objects, easily causing wear and tear on the cable's outer insulation layer, affecting the cable's insulation performance and service life, increasing later maintenance costs and safety hazards. Therefore, a photovoltaic AC cable laying device is proposed to address the above problems. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides a photovoltaic AC cable distributor.

[0004] A photovoltaic AC cable feeder includes a fixed base, a rotating seat fixedly mounted on the top of the fixed base, a rotating vertical rod rotatably mounted inside the rotating seat, and a feeder assembly mounted on the top of the rotating vertical rod.

[0005] The cable feeder assembly includes a positioning vertical rod, a cable harness frame rotatably mounted on the outer side of the positioning vertical rod, a cable fixing tray fixed to the positioning vertical rod and attached to the bottom of the cable harness frame, a telescopic rod attached to the outer side of the rotating vertical rod, an actuating arm fixed to one end of the telescopic rod, and a pulley rotatably mounted on the top of the actuating arm.

[0006] Preferably, a connecting frame is fixedly provided at the top of the rotating vertical rod, a rotating frame is rotatably provided inside the connecting frame, and a plug rod that is inserted into the connecting frame is fixedly provided at the bottom of the rotating frame.

[0007] Preferably, the other end of the telescopic joint rod is fixedly provided with a screw rod that is inserted into the rotating vertical rod, and the outer side of the screw rod is provided with a nut that fits against the surface of the rotating vertical rod.

[0008] Preferably, a spring is fixedly provided on the outer side of the telescopic joint rod, and a hook is provided at the end of the spring.

[0009] Preferably, positioning rings are fixed around the surface of the fixed base, and the hooks of the positioning rings are close together.

[0010] Preferably, a socket is provided at the middle of the rotating vertical rod, and the screw is located inside the socket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a vertical positioning rod structure combined with a pulley structure. During cable protection operations, the cable harness frame can be rotated and retracted to quickly release the outer cable from the pulley, effectively reducing wear between the cable and the ground. This provides efficient cable protection, reducing damage and subsequent maintenance costs. Simultaneously, the spring-hook structure allows for positioning of the rotating positioning rod by attaching the spring hook to the positioning ring, and also allows the spring hook to be attached to the cable for secure cable retraction, preventing it from falling off.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example 1

[0021] like Figures 1 to 5 As shown, this utility model provides a photovoltaic AC cable feeder, including a fixed base 1, a rotating seat 2 fixedly provided at the top of the fixed base 1, a rotating vertical rod 3 rotatably provided inside the rotating seat 2, so as to feed the cable by rotation, and a feeder assembly 4 provided at the top of the rotating vertical rod 3.

[0022] The cable delivery assembly 4 includes a positioning vertical rod 41, a cable bundle frame 42 rotatably mounted on the outer side of the positioning vertical rod 41, a cable fixing tray 43 fixed to the positioning vertical rod 41 attached to the bottom of the cable bundle frame 42, the cable fixing tray 43 positioning the cable bundle frame 42 above, a telescopic rod 8 attached to the outer side of the rotating vertical rod 3, an actuating arm 9 fixed to one end of the telescopic rod 8, a pulley 10 rotatably mounted at the top of the actuating arm 9, the cable is passed through the pulley 10 and the pulley 10 moves the wire to prevent the cable from falling off.

[0023] In this embodiment, a connecting frame 44 is fixedly provided at the top of the rotating vertical rod 3, and a rotating frame 45 is rotatably provided inside the connecting frame 44. A plug rod 46 that is inserted into the connecting frame 44 is fixedly provided at the bottom of the rotating frame 45. Through the rotatable rotating frame 45 structure design, the rotating frame 45 can be rotated to control the positioning vertical rod 41 above to be laid flat, so as to conveniently insert and place the cable harness rack 42.

[0024] The other end of the telescopic joint rod 8 is fixedly provided with a screw rod 6 that is inserted into the rotating vertical rod 3. The outer side of the screw rod 6 is provided with a nut 7 that fits against the surface of the rotating vertical rod 3. The screw rod 6 is inserted into the interior of the rotating vertical rod 3 to position the telescopic joint rod 8.

[0025] A spring 11 is fixedly installed on the outside of the telescopic joint rod 8, and a hook 12 is provided at the end of the spring 11. The added hook 12 structure can serve to quickly connect the spring 11.

[0026] Positioning rings 13 are fixedly provided around the surface of the fixed base 1, and the hooks 12 of the positioning rings 13 are close together to facilitate the quick positioning of the hooks 12 onto different positioning rings 13. An insertion hole 5 is provided in the middle of the rotating vertical rod 3, and the screw 6 is located inside the insertion hole 5 to facilitate the positioning of the telescopic rod 8.

[0027] In this embodiment, the rotating connection between the rotating seat 2 and the rotating vertical rod 3 allows the cable laying assembly 4 to rotate 360° horizontally to adapt to cable laying requirements in different directions. The screw 6 and nut 7 are screwed together to control the extension length of the telescopic rod 8 and adjust the position of the action arm 9, thereby achieving flexible adjustment of the cable laying height and angle. Moreover, the combination of spring 11 and hook 12 provides elastic tension to balance the tension during cable laying and prevent the cable from becoming too loose or too tight. The rotational cooperation between the cable harness frame 42 and the cable fixing tray 43 allows the cable roller to rotate smoothly for cable laying, while the positioning vertical rod 41 ensures structural stability.

[0028] During installation, the fixed base 1 is fixed to the ground or work platform by the positioning ring 13, and the hook 12 is attached to the positioning ring 13. The preload of the spring 11 enhances the overall stability of the equipment and prevents it from shaking during operation.

[0029] Pull the rotating frame 45 upward to release the insertion rod 46 from the constraint of the connecting frame 44. At this time, the rotating frame 45 can rotate around the connecting frame 44 to open. Insert the cable roller into the positioning vertical rod 41 and make its bottom fit against the cable fixing tray 43. Put down the rotating frame 45 and reinsert the insertion rod 46 into the corresponding hole of the connecting frame 44. Lock the cable roller. According to the cable laying path requirements, rotate the rotating vertical rod 3 horizontally to adjust the orientation of the cable feeder assembly 4. Loosen the nut 7 and pull the screw 6 along the insertion hole 5 to adjust the extension length of the telescopic joint rod 8 so that the pulley 10 is aligned with the cable laying target position. Tighten the nut 7 to lock the position of the telescopic joint rod 8. Pass one end of the cable through the pulley 10 and pull it along the predetermined path. When the cable is pulled forward manually or mechanically, the cable harness frame 42 rotates on the positioning vertical rod 41 and the cable roller feeds the cable synchronously. During the feeding process, the spring 11 applies a pulling force to the telescopic joint rod 8 through the hook 12 to maintain the appropriate tension of the pulley 10 on the cable and prevent the cable from tangling or loosening.

[0030] To adjust the cable laying height, the screw 6 can be moved up and down within the socket 5 by rotating the nut 7, which in turn raises and lowers the telescopic rod 8 and the operating arm 9. The pulley 10 at the top of the operating arm 9 can rotate freely to adapt to the cable traction in different directions and reduce frictional resistance. When it is necessary to change the cable laying direction, it is not necessary to move the entire equipment. Simply rotate the rotating vertical rod 3 to adjust the orientation of the cable laying assembly 4. After the cable laying operation is completed, remove the remaining cable roller, loosen the connection between the hook 12 and the positioning ring 13, loosen the nut 7, and retract the telescopic rod 8 to its shortest state to reduce the space occupied by the equipment and facilitate transportation and storage. The cable harness frame 42 is connected to the positioning vertical rod 41 through the bearing to ensure low-friction rotation, low resistance during the laying process, and reduced cable wear. The elastic coefficient of the spring 11 is selected according to the cable specifications (such as wire diameter and weight) to provide appropriate tension. When the cable traction speed is fast, the spring 11 stretches to increase tension and prevent slack; when traction is paused, the spring 11 contracts to prevent the cable from sagging or retracting due to its own weight. The locking principle of screw 6 and nut 7: Screw 6 and nut 7 are fitted with trapezoidal threads, which have self-locking characteristics. After tightening, they can withstand a large axial force, ensuring that the position of telescopic joint rod 8 is fixed. The rotating seat 2 can be equipped with a damping structure or a limiting protrusion to keep the rotating vertical rod 3 stable when it stops at any angle and avoid accidental rotation.
