Description

Technical Field

[0001] This utility model belongs to the technical field of cable laying equipment, specifically relating to an electrical cable laying device based on new energy photovoltaic power generation. Background Technology

[0002] In order to transmit electricity, photovoltaic power plants need to lay electrical cables to connect photovoltaic panels and energy storage equipment. The cable laying (laying) of photovoltaic power plants must follow standardized construction procedures to ensure safety.

[0003] In existing photovoltaic power plants, cable laying is mostly done using mechanical traction or manual traction. The cable reel is pulled along with the cable to lay the cable. Because the existing cable laying device is difficult to adjust the laying resistance, it is easy to cause the cable to be too tight or too loose. In addition, different specifications of cables have different weights, making it even more difficult to lay the cable straight.

[0004] Therefore, an electrical cable laying device based on new energy photovoltaic power generation is proposed. Utility Model Content

[0005] This utility model provides an electrical cable laying device based on new energy photovoltaic power generation, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides an electrical cable laying device based on new energy photovoltaic power generation, including a bracket; a laying reel rotatable on the inner side wall of the bracket; and a laying resistance adjustment component disposed on the laying reel. The laying resistance adjustment component includes: a rotating shaft located at the center of one outer wall of the laying reel; an arcuate groove formed on one outer wall of the rotating shaft; an arcuate guide rod disposed between the inner side wall of the arcuate groove and the outer side wall of the rotating shaft; an adjustment block sliding inside the arcuate groove; a resistance rotating plate rotatable on one outer wall of the rotating shaft near the arcuate groove; a spring disposed between the resistance rotating plate and the adjustment block; a limiting block on the outer side wall of the arcuate guide rod; and a fastening screw threaded onto one outer wall of the adjustment block.

[0007] Furthermore, a number of positioning holes are equally spaced on one side of the inner wall of the arc groove, and a spring plunger that matches the positioning holes is embedded on one side of the outer wall of the adjusting block.

[0008] Furthermore, the support is provided with a wire feeding blocking assembly, which includes a ring located on the outer side of one side of the support near the outer side of the rotating shaft, and baffles are axially spaced at equal intervals on the inner side wall of the ring.

[0009] Furthermore, the rotating shaft passes through the bracket, and the rotating shaft and the bracket are rotatably connected;

[0010] By adopting the above technical solution, it is possible to ensure that the pay-off reel and the rotating shaft rotate synchronously and that the rotation is stable.

[0011] Furthermore, the arc-shaped guide rod passes through the adjusting block and the resistance plate;

[0012] By adopting the above technical solution, the adjusting block and the resistance rotating plate can make axial circular motion along the arc guide rod.

[0013] Furthermore, a groove is provided on the outer wall of the rotating shaft to allow the resistance plate to rotate;

[0014] By adopting the above technical solution, the resistance plate can rotate smoothly.

[0015] Furthermore, a screw head is provided at one end of the fastening screw;

[0016] By adopting the above technical solution, it is ensured that when the fastening screw rotates, the screw head can be pressed against one end of the rotating shaft to achieve positional fixation, thereby achieving positional fixation of the adjusting block.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention adjusts the axial distance between the adjusting block and the resistance plate by adjusting the position of the adjusting block in different positions of the arc groove, thereby changing the extension and contraction state of the spring.

[0028] Reference Figure 1-5This utility model embodiment proposes an electrical cable laying device based on new energy photovoltaic power generation, including a bracket 1. A laying reel 2 is rotatably connected to the inner side wall of the bracket 1. A rotating shaft 31 of a laying resistance adjustment component 3 is set at the center of one side outer wall of the laying reel 2. The rotating shaft 31 passes through the bracket 1 and is rotatably connected to the bracket 1 to ensure that the laying reel 2 and the rotating shaft 31 rotate synchronously and to ensure rotational stability. An arc groove 32 is formed on the outer wall of the rotating shaft 31 away from the laying reel 2. An arc guide rod 33 is set between the inner wall of one side of the arc groove 32 and the outer wall of one side of the rotating shaft 31. An adjusting block 34 is slidably connected inside the arc groove 32. A resistance rotating plate 35 is rotatably connected to the outer wall of the rotating shaft 31 adjacent to the arc groove 32. The arc guide rod 33 passes through the adjusting block 34 and the resistance rotating plate 35, which allows the adjusting block 34 to... The resistance plate 35 moves axially around the arc guide rod 33. A spring 36 is provided on the top of the adjusting block 34 and on one side of the outer wall of the resistance plate 35. The spring 36 is sleeved on the outside of the arc guide rod 33. A groove is provided on the outer wall of the rotating shaft 31 to allow the resistance plate 35 to rotate smoothly. The axis of the arc groove 32 and the arc guide rod 33 is on the same axis as the rotation point of the resistance plate 35. A limit block 37 is provided on the outer wall of the arc guide rod 33 near the other side of the resistance plate 35. A fastening screw 38 is connected to the center of the outer wall of the adjusting block 34 away from the adjusting block 34 by a thread. One end of the fastening screw 38 is provided with a screw head to ensure that when the fastening screw 38 rotates, the screw head can be pressed against one end of the rotating shaft 31 to fix the position, thereby fixing the position of the adjusting block 34.

[0029] A ring 41 of the wire feeding blocking assembly 4 is provided on the outer side wall of the bracket 1 near the outer side of the rotating shaft 31, and baffles 42 are provided axially at equal intervals on the inner side wall of the ring 41.

[0030] A number of positioning holes 39 are evenly spaced on one side of the inner wall of the arc groove 32. A spring plunger that matches the positioning hole 39 is embedded on one side of the outer wall of the adjusting block 34. The positioning of the adjusting block 34 is achieved through the cooperation between the positioning hole 39 and the spring plunger, ensuring that the adjusting block 34 is firmly fixed in the limit position.

[0031] The specific implementation method is as follows: When laying electrical cables in a new energy photovoltaic power plant, the cable to be laid is wound on the cable reel 2, the bracket 1 is placed on a horizontal ground and fixed. When laying the cable, one end of the cable is pulled by mechanical traction or manual assistance. When the cable is pulled, the cable reel 2 rotates synchronously. The cable is laid by rotating the cable reel 2.

[0032] Because the cable needs to be laid neither too tightly nor too loosely to prevent breakage due to temperature differences, the resistance when pulling the cable is adjusted to ensure that the cable is straight during the pulling process. When the rotating shaft 31 rotates synchronously with the cable reel 2, the resistance rotating plate 35 on the rotating shaft 31 moves in a circular motion. When the resistance rotating plate 35 contacts the baffle 42, the baffle 42 blocks the movement of the resistance rotating plate 35. The resistance rotating plate 35 rotates after being subjected to force. During the rotation, the resistance rotating plate 35 squeezes the spring 36, and the spring 36 is compressed. The resistance force is used to control the cable laying speed and maintain resistance during pulling to ensure that the cable is straight.

[0033] To adjust the straightening state of cables of different specifications during laying, the rotational resistance of the resistance plate 35 can be adjusted, thereby adjusting the cable feeding resistance of the cable feeding reel 2. Specifically, loosen the fastening screw 38 and slide the adjusting block 34 in the arc groove 32. Since the resistance plate 35 is in a state of being blocked on one side under the limit of the limiting block 37, by adjusting the position of the adjusting block 34, the distance between the adjusting block 34 and the resistance plate 35 is changed, thereby changing the extension and contraction state of the spring 36, thereby adjusting the deformation capacity of the spring 36 under pressure, and achieving the purpose of adjusting the cable feeding resistance of the cable feeding reel 2.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
