[0021] It should be noted that similar numbers and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In the description of the embodiments of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, and it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] Example: Combination Figures 1 to 7 As shown, an embodiment of the present invention provides a photovoltaic power station cable installation and laying device, and the specific structure is described as follows.

[0023] Reference Figure 1 As shown, the photovoltaic power station cable installation and laying device of the present invention mainly includes a bracket 2, a traction assembly 3 and a clamping assembly 4, wherein the bracket 2 includes a first support rod 21 and a second support rod 22, the first support rod 21 and the second support rod 22 are respectively vertically aligned with the two sides of the L-shaped embedded pipe 1 below, and the ends of the first support rod 21 and the second support rod 22 are fixedly connected to form an L-shaped bracket 2. The L-shaped structural design of the bracket 2 can better adapt to the shape of the L-shaped embedded pipe 1, and the L-shaped structure occupies a relatively small volume compared to other shapes, saving raw materials.

[0024] like Figure 2As shown, a circular ring is installed on the first support rod 21 and the second support rod 22, and the circular ring is connected to the limit frame 23 to achieve a sliding connection. The lower end of the limit frame 23 clamps and limits the outer wall of the L-shaped embedded pipe 1. The limit frame 23 mainly plays a limiting role. The bottom of the limit frame 23 that clamps and limits the L-shaped embedded pipe 1 can be a U-shaped support with an opening downward. On the one hand, the limit frame 23 can be used to limit the L-shaped embedded pipe 1, so that the L-shaped embedded pipe 1 can be kept relatively stable during the entire cable laying process, which is convenient for laying cables. On the other hand, the limit frame 23 can also support the bracket 2, which is convenient for the staff to support the bracket 2. In addition, the limit frame 23 is slidably connected to the bracket 2, so that the position of the limit frame 23 can be flexibly adjusted according to the actual working conditions, which is more flexible and convenient to use.

[0025] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, the mounting plate 24 is fixedly connected to the lower part of the L-shaped bracket 2. The traction assembly 3 includes a driving motor 32, which is fixedly mounted on the mounting plate 24. An adjusting frame 33 is provided at the bottom of the mounting plate 24. A transmission shaft 34 is rotatably connected to the adjusting frame 33, a belt is connected between the output end of the driving motor 32 and the transmission shaft 34, and a reel 35 is fixedly connected to the transmission shaft 34. The reel 35 is mainly used to wind and unwind the first traction rope 31. The two ends of the first traction rope 31 are fixedly connected to the reel 35 and the connecting pipe 41 of the clamping assembly 4, respectively.

[0026] It should be noted that the end of the first traction rope 31 connected to the connecting tube 41 of the clamping assembly 4 can be an integrated structure. It can also be a split structure, for example: a connecting ring can be provided at the end of the connecting tube 41 away from the cable, and the first traction rope 31 can be tied to the connecting ring and fixedly connected to the connecting tube 41.

[0027] In some implementations of this embodiment, Figure 3 and Figure 4 As shown, the clamping assembly 4 is used to clamp one end of the cable inserted into the connecting tube 41, and the pulling assembly 3 is used to drag the connecting tube 41 through the entire L-shaped pre-buried tube 1. Among them, the diameter of the connecting tube 41 is smaller than the diameter of the L-shaped pre-buried tube 1, which facilitates the movement of the connecting tube 41 in the L-shaped pre-buried tube 1. When in use, first extend one end of the cable into the interior of the connecting tube 41, and then use the clamping assembly 4 to clamp one end of the cable so that the cable and the connecting tube 41 are fixed together. Then, use the pulling assembly 3 to pass the connecting tube 41 from one end of the L-shaped pre-buried tube 1, and then pass it out from the other end of the L-shaped pre-buried tube 1, so as to realize the laying of the cable in the L-shaped pre-buried tube 1.

[0028] Furthermore, if Figure 5-Figure 6As shown, the clamping assembly 4 includes a guide hole 411 opened on the connecting tube 41 and arranged along its radial direction, a slidable clamping rod 43 is inserted into the guide hole 411, and a clamping ring 42 is installed on the outer wall of the connecting tube 41. The clamping ring 42 can be squeezed and matched with the outer end of the clamping rod 43 so that the inner end of the clamping rod 43 moves toward the inside of the connecting tube 41 to clamp the outer surface of the cable.

[0029] It should be noted that the clamping ring 42 can be threadedly connected to the outer wall of the connecting pipe 41, so that the position of the clamping ring 42 on the connecting pipe 41 can be kept more stable, and it is also convenient to adjust the axial position of the clamping ring 42 on the connecting pipe 41.

[0030] Combination Figure 7 As shown, the clamping ring 42 is pressed and matched with the top end of the clamping rod 43, that is, the clamping ring 42 can be pressed and matched with the top end of the clamping rod 43 when it moves to the left, and it can be not matched with the clamping ring 42 when it moves to the right. Specifically, when it is necessary to clamp and lay the cable, one end of the cable is inserted into the connecting tube 41, and then the clamping ring 42 is rotated to move along the axial direction of the connecting tube 41. During the movement, the clamping ring 42 will contact one end of the clamping rod 43, and then the clamping rod 43 will be pressed. The clamping rod 43 will move toward the inside of the connecting tube 41 under pressure, so that the cable can be compressed and fixed together with the connecting tube 41. When the cable is laid, the clamping ring 42 is rotated in the opposite direction, so that the clamping ring 42 will gradually separate from one end of the clamping rod 43, so that the clamping rod 43 will release the pressure on the cable, which is convenient for the cable to be separated from the connecting tube 41.

[0031] In this embodiment, if Figure 7 As shown, the top end of the clamping rod 43 is provided with a first inclined surface 431 which is higher on the left and lower on the right, and in the radial direction of the connecting tube 41, the distance between the side of the first inclined surface 431 close to the clamping ring 42 and the axis of the connecting tube 41 is smaller than the distance between the side of the first inclined surface 431 away from the clamping ring 42 and the axis of the connecting tube 41. The first inclined surface 431 mainly plays the role of guiding and transition. Specifically, in the radial direction of the connecting tube 41, the distance between the side of the first inclined surface 431 close to the clamping ring 42 and the axis of the connecting tube 41 is set to be smaller than the distance between the side of the first inclined surface 431 away from the clamping ring 42 and the axis of the connecting tube 41. In this way, when the clamping ring 42 contacts one end of the clamping rod 43, the first inclined surface 431 of the clamping ring 42 can be used to contact one end of the clamping rod 43 and gradually squeeze one end of the clamping rod 43. In this way, the friction between the clamping ring 42 and the clamping rod 43 can be reduced, which can save effort and extend the service life of the clamping ring 42 and the clamping rod 43.

[0032] Further, such as Figure 7 As shown, the clamping ring 42 is provided with a second inclined surface 421, which is parallel to the first inclined surface 431. Similarly, the second inclined surface 421 also mainly plays a guiding and transitional role, and the friction between the clamping ring 42 and the clamping rod 43 can be further reduced through the extrusion fit between the first inclined surface 431 and the second inclined surface 421.

[0033] In addition, if Figure 6 and Figure 7 As shown, in the axial direction of the connecting tube 41, the cross-sectional shapes of the guide hole 411 and the clamping rod 43 are both T-shaped, a step portion is provided in the guide hole 411, a step portion is provided on the clamping rod 43, and an elastic member 44 is installed between the step portions. Among them, the elastic member 44 mainly plays the role of providing a restoring force, and the elastic member 44 can be a spring. The elastic member 44 can connect the clamping rod 43 with the guide hole 411 to reduce the situation where the clamping rod 43 is separated from the guide hole 411. In addition, when the clamping rod 43 moves inward under the action of the clamping ring 42 to clamp the cable, the elastic member 44 is compressed at this time. When the cable is laid, the clamping ring 42 is separated from the clamping rod 43, and the clamping rod 43 will return to its original position under the action of the restoring force of the elastic member 44, thereby relieving the pressure of the clamping rod 43 on the cable.

[0034] As an optional embodiment, Figure 7 As shown, the end of the connecting tube 41 away from the cable is constructed as a hemispherical structure. When the power pulls the connecting tube 41, the end of the connecting tube 41 away from the cable first enters the interior of the L-shaped pre-buried tube 1. Therefore, the end of the connecting tube 41 away from the cable is constructed as a hemispherical structure, which can reduce the friction between the connecting tube 41 and the inner wall of the L-shaped pre-buried tube 1, making the movement of the connecting tube 41 smoother and facilitating the laying of the cable.

[0035] As an optional embodiment, Figure 4 and Figure 7 As shown, a plurality of balls 422 (preferably 4 in this embodiment) are mounted on the outer peripheral wall of the clamping ring 42, and the plurality of balls 422 are distributed in a circular array about the axis of the connecting tube 41. It should be noted that the balls 422 can rotate freely on the clamping ring 42, and the balls 422 mainly play the role of reducing friction. Since the diameter of the clamping ring 42 is larger than the diameter of the connecting tube 41, when the connecting tube 41 drives the cable to move, the clamping ring 42 is easy to contact the inner wall of the L-shaped pre-buried tube 1, and the balls 422 can convert the sliding friction between the clamping ring 42 and the inner wall of the L-shaped pre-buried tube 1 into rolling friction, thereby further facilitating the laying of the cable.

[0036] As an optional embodiment, Figure 6 and Figure 7As shown, the guide holes 411 and the clamping rods 43 are provided in multiple numbers and correspond one to one, and the multiple guide holes 411 are distributed in a circular array about the axis of the connecting tube 41. The guide holes 411 and the clamping rods 43 are provided in multiple numbers, so that when the clamping ring 42 is rotated, the clamping ring 42 can squeeze one end of the multiple clamping rods 43 at the same time, so that the multiple clamping rods 43 can compress the cables at the same time, thereby making the connection between the clamping rods 43 and the connecting tube 41 more secure and stable. In this embodiment, the number of the guide holes 411 and the clamping rods 43 are both three, and of course, other suitable numbers can also be used.

[0037] When in use, firstly, the first traction rope 31 is passed through the entire L-shaped pre-buried tube 1, and then the cable is fixedly connected to the connecting tube 41. After the connection is completed, the driving motor 32 is started, and the driving motor 32 drives the transmission shaft 34 to rotate through the belt, and the rotation of the transmission shaft 34 then drives the winding wheel 35 to rotate, and the rotation of the winding wheel 35 in turn drives one end of the first traction rope 31 to be wound around the winding wheel 35, and then the first traction rope 31 can drive the connecting tube 41 to move inside the L-shaped pre-buried tube 1, so that the cable can be laid.

[0038] As an optional embodiment, Figure 1 and Figure 2 As shown, the traction assembly 3 also includes an angle adjuster 25, and the two sides of the angle adjuster 25 are fixedly connected to the mounting plate 24 and the adjustment frame 33 respectively. It should be noted that the angle adjuster 25 is a prior art, which is mainly used to adjust the angle of the adjustment frame 33 in the vertical direction. Specifically, when in use, the angle adjuster 25 can be adjusted in the vertical direction so that the bottom of the winding wheel 35 is located in the middle position of the connecting pipe 41, so that the friction between the first traction rope 31 and the pipe mouth of the L-shaped embedded pipe 1 can be avoided, which is conducive to extending the service life of the first traction rope 31. Of course, the angle of the winding wheel 35 can also be adjusted according to the actual working conditions, which is more flexible to use.

[0039] In some implementations of this embodiment, Figure 1 As shown, a second traction rope 5 is fixedly connected to the side of the connecting tube 41 facing the cable, and a magnet 51 is fixedly connected to the end of the second traction rope 5 away from the connecting tube 41. The second traction rope 5 mainly plays a traction role. Before clamping the cable, the end of the first traction rope 31 connected to the connecting tube 41 needs to pass through the entire L-shaped pre-buried tube 1. At this time, another magnet with different magnetic properties can be used on the outside of the L-shaped pre-buried tube 1 to cooperate with the magnet 51 of the second traction rope 5, so that the first traction rope 31 can pass through the inside of the L-shaped pre-buried tube 1, which is convenient to use.
