Description

Technical Field

[0001] This utility model relates to the field of synchronous cable laying technology, and in particular to a photovoltaic array synchronous cable laying mechanism. Background Technology

[0002] With the rapid development of the photovoltaic industry, the scale of photovoltaic power generation systems is gradually expanding. Especially in large-scale photovoltaic power plants, the layout of photovoltaic arrays is becoming increasingly complex, and cable laying has become a key aspect of system design. During the laying process, a large number of cables need to be laid simultaneously and precisely to ensure cable tension, neat arrangement, and to avoid cable crossing, bending, and damage. The difficulty of cable laying is greatly increased, especially in the arrangement of photovoltaic modules with different tilt angles and different types. This is quite common in the installation and laying process of photovoltaic equipment.

[0003] Existing technologies, such as the utility model patent with publication number CN217626792U, disclose a photovoltaic cable laying device. This patent includes an installation platform. A first side plate is fixedly connected to the top outer wall of the installation platform near one edge. Two horizontal bars are fixedly connected to the side wall of the first side plate near its bottom. A second side plate is provided on the top of the installation platform. Two rod holes are opened on the outer wall of the second side plate near its bottom. The ends of the two horizontal bars are inserted through the rod holes. Two electrically operated telescopic rods are fixed to the top outer wall of the installation platform by bolts. A top plate is fixed to the top of each of the electrically operated telescopic rods by bolts. The two top plates are fixedly connected to the same support block at opposite ends. The end face structure of the support block is H-shaped, and the top surface of the support block is arc-shaped. This utility model is a photovoltaic cable laying device that can place photovoltaic cables, making it easier for workers to pull out the cables for laying, thus improving the practicality of the device.

[0004] During the installation and laying of photovoltaic equipment, it was found that when laying cables in photovoltaic panel equipment, the general photovoltaic cable laying equipment can only lay a single photovoltaic cable. However, since photovoltaic panels are usually assembled in multiple sections, it is inconvenient to lay multiple cables at the same time. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when laying cables in photovoltaic panel equipment, general photovoltaic cable laying equipment can only lay a single photovoltaic cable, while photovoltaic panels are usually assembled from multiple sections. This results in the inconvenience of laying multiple cables at the same time.

[0006] To solve the above technical problems, this utility model provides a photovoltaic array synchronous cable laying mechanism, comprising: a frame, with movable frames fixedly connected to the upper surfaces of both ends of the frame; a plurality of evenly distributed roller frames are provided on the upper surface of the frame, with cables wound around the inner arc surface of the roller frames; an adjustment device is provided on the upper surface of the frame corresponding to the positions of the roller frames; the adjustment device includes an adjustment ring, a first pulley, and a second pulley; the lower surface of the adjustment ring is fixedly connected to the upper surface of the frame; grooves are formed on both sides of the adjustment ring; a plurality of bases are slidably connected to the surface of the adjustment ring corresponding to the positions of the grooves; rollers are rotatably connected to both sides of the lower surface of each base; and the arc surface of the rollers is aligned with the inner arc surface of the rollers. The inner wall of the chute is slidably connected. A connecting plate is fixedly connected to one side of the lower surface of the base. A pressing rod is threaded through the surface of the connecting plate. The bottom end of the pressing rod abuts against the surface of the frame. Slide rails are fixedly connected to the four sides of the frame at positions corresponding to the roller frame. Several support frames are slidably connected to the surface of the slide rails. Positioning grooves are opened on both sides of the support frames. The first pulley and the second pulley are located inside the support frames. Adjusting rods are fixedly connected to the inner walls of the first pulley and the second pulley. The arc surface of the adjusting rod is slidably connected to the inner wall of the positioning groove. The same fixing plate is fixedly connected to one side of the two adjusting rods. An adjusting shaft is threadedly connected to the arc surface of one of the adjusting rods.

[0007] The aforementioned components achieve the following effects: the adjusting ring, its groove, and the sliding base allow operators to flexibly adjust the cable exit positions on multiple roller frames according to the actual laying path, ensuring that multiple cables remain synchronized during laying and avoiding tangling and confusion. The first and second pulleys slide in the positioning slots of the support frame via adjusting rods, changing the distance between them to accommodate cables of different diameters and apply appropriate clamping force, ensuring stable cable tension and smooth cable exit during laying. The adjusting shaft is used to lock the position of the adjusting rod and fix the pulley spacing. The entire device is compact and flexible in adjustment, greatly improving the efficiency and reliability of multi-line synchronous laying in photovoltaic arrays.

[0008] Preferably, a side plate is fixedly connected to one side surface of the support frame. The side plate has an "L" shaped cross section. A positioning shaft is threaded through one side surface of the side plate. A compression pad is fixedly connected to one end of the positioning shaft. The surface of the compression pad abuts against the side wall surface of the slide rail.

[0009] The effect achieved by the above components is that by turning the positioning shaft, the compression pad at its end will press tightly against the side of the slide rail, generating huge friction force, thereby firmly locking the entire support frame in any position of the slide rail.

[0010] Preferably, the inner arc surfaces of the first pulley and the second pulley are each fixedly connected with a plurality of friction strips, the friction strips being rubber strips.

[0011] The effect achieved by the above components is that rubber friction strips are provided on the inner walls of the first and second pulleys, which effectively increases the friction between the pulleys and the cable surface.

[0012] Preferably, the support frame is a stainless steel frame, and the height of the support frame is adapted to the height of the roller frame.

[0013] The aforementioned components achieve the following effect: by using stainless steel to make the support frame, the components are guaranteed to have excellent corrosion resistance and sufficient structural strength in the complex environment of outdoor photovoltaic power stations, thus extending the service life of the equipment.

[0014] Preferably, an auxiliary device is provided on the base surface corresponding to the position of the roller frame. The auxiliary device includes a fixed rail, the lower surface of which is rotatably connected to the surface of the base. An auxiliary frame is slidably connected to both ends of the surface of the fixed rail. A support plate is fixedly connected to the upper surface of the auxiliary frame. An insert plate is fixedly connected to the upper surface of the support plate. A through column is fixedly connected to one side of the surface of the auxiliary frame. A drive rod is threaded through the inner wall of the through column. The bottom end of the drive rod abuts against the surface of the fixed rail. Positioning frames are fixedly connected to both sides of the upper surface of the roller frame. The inner wall of the positioning frame is inserted into the surface of the insert plate.

[0015] The aforementioned components achieve the following effect: by sliding the auxiliary frame, the distance between the two insert plates can be adjusted to align them with the positioning frame on the roller frame, allowing the upper insert plate of the support plate to insert into the positioning frame, thus completing the load-bearing and fixing of the roller frame. Rotating the drive rod allows its bottom end to press against the fixed rail, thereby fixing the entire auxiliary frame in place. This device makes the replacement of cable roller frames extremely simple and quick, eliminating the need for complicated bolt connections and significantly improving work efficiency.

[0016] Preferably, the two sides of the insert plate are tapered, and the cross-sectional dimensions of the insert plate are adapted to the cross-sectional dimensions of the inner wall of the positioning frame.

[0017] The effect achieved by the above components is that even with slight positional deviations, the inclined plane can automatically guide the insertion of the positioning frame, making it easy to insert, reducing the accuracy requirements of operation and making the installation process smoother.

[0018] Preferably, the upper arc surface of the drive rod is provided with a plurality of auxiliary grooves, and the plurality of auxiliary grooves are evenly distributed on the surface of the drive rod.

[0019] The effect achieved by the above components is that the auxiliary grooves on the surface of the drive rod can increase the surface texture and coefficient of friction of the hand-held part.

[0020] Compared with related technologies, the photovoltaic array synchronous cable laying mechanism provided by this utility model has the following beneficial effects:

[0021] This invention provides a photovoltaic array synchronous cable laying mechanism. Through the operation of the adjustment device, precise and flexible adjustment of the output position and guide spacing of multiple cables is achieved. The base on the adjustment ring can slide independently along the chute, allowing the cables on each roller frame to be guided to different laying paths according to the actual layout of the photovoltaic array. This perfectly solves the problems of crossing and tangling that easily occur when laying multiple cables synchronously. Simultaneously, the distance between the first and second pulleys can be easily adjusted and locked via the adjustment rod, accommodating cables of different diameters and providing stable clamping and guidance for the cables. This ensures uniform tension and smooth cable exit during laying, greatly improving laying efficiency and line neatness.

[0022] By operating the auxiliary device, the cable roller frame can be quickly installed, removed, and replaced. This device replaces the traditional bolt fastening method with the insertion of the insertion plate and the positioning frame. Operators only need to align and move the roller frame to complete the installation, and tightening the drive rod will lock it in place. The disassembly process is equally simple, greatly shortening the operation time for replacing empty drums or adding new cable drums, reducing labor intensity, and making it particularly suitable for photovoltaic power station applications that require frequent and continuous large-scale cable laying, significantly improving overall construction efficiency.

[0034] The working principle of the photovoltaic array synchronous cable laying mechanism provided by this utility model is as follows: The coiled cables 6 are installed onto each roller frame 3. Based on the arrangement of the photovoltaic array and the path to be laid, the base 403 on the adjusting ring 401 is manually slid to form a "comb-like" distribution matching the laying direction. After adjustment, the pressing rod 405 is tightened to lock the position of the base 403. This step ensures that multiple cables 6 will not interfere with each other when led out from the frame 1, laying the foundation for synchronous laying. The ends of the cables 6 on each roller frame 3 are sequentially passed through a pulley group composed of a first pulley 414 and a second pulley 416. Based on the diameter of the cable 6, the adjusting rod 412 is slid to adjust the distance between the two pulleys, ensuring that the cable 6 is securely clamped without damaging it. After adjustment, the position of the adjusting rod 412 is locked on the support frame 407 by rotating the adjusting shaft 413. The moving frames 2 at both ends of the frame 1 are connected by the traction device, and the entire mechanism is dragged forward at a constant speed along the rows of the photovoltaic array. During the movement, all cables 6 are pulled out from their respective roller frames 3 synchronously and smoothly under the control of the pulley group and laid on the ground.

[0035] During the laying process, if the position of a particular cable 6 needs to be fine-tuned, the positioning shaft 409 can be loosened, the entire support frame 407 can be slid on the slide rail 406 to change the lateral lead-out point of the cable 6, and then the positioning shaft 409 can be tightened again. When the cable 6 on a certain roller frame 3 is exhausted, no tools are needed. Simply loosen the drive rod 57 of the auxiliary device 5 and slide the insert plate 55 out of the positioning frame 51 to remove the empty roller frame 3. After replacing the roller frame 3 with one full of cable 6, reinsert the insert plate 55 and tighten the drive rod 57 to quickly resume operation, greatly reducing downtime.
