Description

Technical Field

[0001] This invention belongs to the technical field of cable laying equipment, specifically relating to a cable laying device for photovoltaic power stations and its usage method. Background Technology

[0002] With the continuous expansion of photovoltaic power plant construction, the amount of cable laying work has increased significantly. In actual construction, a large number of cables need to be laid over long distances, crossing supports, equipment foundations, corner areas, and complex terrain. Due to the long length and heavy weight of photovoltaic cables, problems such as high frictional resistance, difficulty in dragging, easy cable deviation and detachment from the track, and wear of the outer sheath are common during laying. Especially when the cable passes through corner areas, the change in the direction of the traction force can easily cause the cable to jump, tilt, or detach from the guide rollers, which not only increases the labor intensity of construction workers but also seriously restricts laying efficiency and quality.

[0003] Currently, the cable guiding devices used at photovoltaic power plant construction sites are typically simple support rollers or guide rollers, which only provide basic support and guidance functions and are insufficient to meet the high-efficiency laying requirements under complex working conditions. The main shortcomings of this type of device are as follows:

[0004] First, the height of the support rollers or guide rollers is fixed and cannot be adjusted. When facing different terrain undulations and different laying height requirements, the site adaptability of the device is poor, often requiring construction personnel to temporarily scaffold or repeatedly adjust the position of the device, which affects construction efficiency;

[0005] Second, it lacks active drive function. The cable movement relies entirely on external traction force to drag it. The frictional resistance between the cable and the support rollers or guide rollers is large, which can easily lead to wear on the cable surface and affect the cable's service life. The dragging difficulty increases significantly, especially when laying cables over long distances.

[0006] Third, there is a lack of effective flattening and limiting mechanisms. Cables are prone to jumping, tilting, or coming off the track during installation, and these problems are more pronounced at bends, affecting the continuity and safety of the installation.

[0007] In summary, existing cable laying devices have significant shortcomings in height adjustment, active drive, and flattening limit functions. There is an urgent need to design a multi-functional cable laying device for photovoltaic power plants to improve construction efficiency, laying quality, and operational safety. Summary of the Invention

[0008] This invention provides a photovoltaic power station cable laying device and its usage method, aiming to solve the technical problems of existing cable guiding devices, such as fixed and non-adjustable height, lack of active driving function, and lack of flattening and limiting mechanism.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a photovoltaic power station cable laying device, comprising a base, wherein a guiding mechanism and a guide wheel assembly are provided on the base along the cable traveling direction; the guiding mechanism is used to initially guide the cable; and the guide wheel assembly is provided with a flattening mechanism for cooperating with the guide wheel assembly to limit the cable.

[0010] The guide wheel assembly includes two mounting shells located on both sides of the upper surface of the base and arranged opposite to each other. Each mounting shell is rotatably connected to a vertically arranged screw, and a sliding block is threaded onto the screw. A guide wheel body for supporting the cable is rotatably connected between the two sliding blocks.

[0011] The guide wheel assembly also includes a drive component for driving the screws on both sides to rotate synchronously, thereby driving the sliding block to rise and fall, and driving the guide wheel body to rise and fall through the sliding block.

[0012] As a limitation of the present invention, the drive assembly includes a dual-axis motor fixed on the base, and the two output ends of the dual-axis motor are respectively connected to a first worm and a second worm.

[0013] The bottom of the two screws is respectively fixed with a first worm gear and a second worm gear, the first worm gear meshing with the first worm, and the second worm gear meshing with the second worm.

[0014] As a further limitation of the present invention, the first worm and the second worm are respectively rotatably connected to the base via bearings.

[0015] As another limitation of the present invention, the flattening mechanism includes two sets of linkage assemblies arranged symmetrically; each set of linkage assemblies includes a first linkage, a second linkage, a third linkage and a pressure plate, the first end of the first linkage is fixed to the mounting shell, the second end of the first linkage is hinged to the first end of the second linkage, the second end of the second linkage is hinged to the first end of the third linkage, and the second end of the third linkage is hinged to the pressure plate;

[0016] Each of the connecting rod assemblies also includes a cylinder, the bottom end of which is fixed to the mounting housing, and the top end of which is hinged to the middle of the second connecting rod, for driving the pressure plate to press down or lift up.

[0017] As a further limitation of the present invention, a horizontal plate is hinged between the two pressure plates in the two sets of connecting rod assemblies; when the two pressure plates are pressed down, they together with the horizontal plate form a downward-opening limiting groove to limit the cable to be located above the guide wheel body.

[0018] As a further limitation of the present invention, each group of the connecting rod assembly is provided with two cylinders, and the two cylinders are arranged side by side.

[0019] As a third limitation of the present invention, it also includes a drive motor fixed to the sliding block by a mounting plate, the drive motor being connected to the guide wheel body via a pulley set for driving the guide wheel body to rotate actively.

[0020] As a further limitation of the present invention, the guiding mechanism includes two columns located on both sides of the upper surface of the base and arranged opposite to each other, and each column is fixed with an inner support and an outer support.

[0021] Each of the columns is slidably fitted with a support arm, and an upper guide roller is rotatably connected between two of the support arms;

[0022] A lower guide roller is rotatably connected between the two inner supports;

[0023] Each of the outer supports has a pressure plate extending from its top end, the pressure plate being fixed to the top end of the column;

[0024] A spring is fitted on the top of the column. The lower end of the spring abuts against the support arm, and the upper end abuts against the pressure plate. The preload of the spring causes the upper guide roller and the lower guide roller to form an elastic pressure clamping.

[0025] As a further limitation of the present invention, both ends of the upper guide roller and the lower guide roller are integrally formed with limit plates.

[0026] The present invention also relates to a method of using a photovoltaic power station cable laying device, applied to the photovoltaic power station cable laying device as described above, comprising the following steps:

[0027] S1. The cable is introduced into the guiding mechanism. Under the elastic action of the spring, the upper guide roller and the lower guide roller form an elastic pressure clamp to initially guide the cable.

[0028] S2. Start the drive component of the guide wheel assembly, drive the screws on both sides to rotate synchronously, drive the sliding block to rise and fall, and drive the guide wheel body to rise and fall to the required height through the sliding block;

[0029] S3. Start the cylinder to drive the pressure plate of the flattening mechanism to press down, forming a limiting groove with the horizontal plate, limiting the cable above the guide wheel body, and cooperating with the guide wheel body to achieve centering guidance;

[0030] S4. Start the drive motor, which drives the guide wheel body to rotate actively through the pulley set, assisting the cable conveyor to move forward.

[0031] By adopting the above-described technical solution, the beneficial effects achieved by this invention compared to the prior art are as follows:

[0032] (1) By setting up a guide wheel assembly, the drive component drives the screws on both sides to rotate synchronously, which drives the sliding block and the guide wheel body to rise and fall as a whole. The height can be quickly adjusted according to different construction environments and different cable laying heights, solving the problem that the height of existing support wheels or guide wheels is fixed and cannot be adjusted, and improving the site adaptability and construction flexibility of the device.

[0033] (2) By setting up a drive motor and a pulley group to drive the guide wheel body to rotate actively, the guide wheel body forms an active conveying effect on the cable, which reduces the cable dragging resistance and reduces the friction and wear between the cable and the guide wheel body. This solves the problem of the lack of active drive function in the existing device, enabling the cable to be laid more smoothly and continuously, and improving construction efficiency.

[0034] (3) By setting up a flattening mechanism, the cylinder drives the connecting rod assembly to push the pressure plate down, which together with the horizontal plate forms a downward-opening limiting groove, limiting the cable to be located above the guide wheel body. This effectively suppresses the jumping, lifting and deviation of the cable during the process of travel, solves the problem of the lack of flattening and limiting mechanism in the existing device, and improves the stability and guiding accuracy during the cable laying process.

[0035] (4) By setting up a guiding mechanism, the upper and lower guide rollers form an elastic pressure clamp under the elastic action of the spring, which can automatically adjust the clamping force according to different specifications of cables, and provide preliminary guidance for the cables, so that the cables can run smoothly and prevent the cables from swinging left and right or falling off, thus improving the running stability of the cables before entering the guide roller body.

[0046] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0047] This embodiment provides a cable laying device for a photovoltaic power station. This device can be installed at corner stations along the cable laying path of a photovoltaic power station. By installing this device at different corner stations along the laying path, it can provide cable guidance, height adjustment, active conveying, and flattening / limiting functions.

[0048] like Figures 1 to 4 As shown, the photovoltaic power station cable laying device provided in this embodiment includes a base 1. Each of the four corners of the base 1 is equipped with a movable wheel 101 with a braking function to facilitate the overall movement and positioning of the device. During laying operations, the braking function can lock the device's position to prevent accidental movement. A guide mechanism 4 and a guide wheel assembly 2 are sequentially arranged on the upper surface of the base 1 along the cable travel direction. A flattening mechanism 3 is installed on the top of the guide wheel assembly 2 to limit the cable's movement. The components are described in detail below.

[0049] 1. Guide wheel assembly 2

[0050] like Figure 2 and Figure 3 As shown, the guide wheel assembly 2 includes a mounting housing 201, a screw 203, a sliding block 204, a guide wheel body 205, and a drive assembly.

[0051] Two mounting shells 201 are provided, fixed to the left and right sides of the upper surface of the base 1, respectively, with the two mounting shells 201 facing each other. Each mounting shell 201 is a hollow shell structure, with a vertically arranged screw 203 rotatably connected inside. Each mounting shell 201 has a vertical opening 202 extending along its height on its side wall, connecting the interior of the mounting shell 201 to the exterior. A sliding block 204 is threaded onto the screw 203, and the sliding block 204 can move vertically within the mounting shell 201. A portion of the sliding block 204 extends out of the mounting shell 201 through the vertical opening 202. The two ends of the guide wheel body 205 are rotatably connected to the portions of the two sliding blocks 204 extending out of the mounting shell 201. The axis of the guide wheel body 205 is perpendicular to the extension direction of the cable. The cable lies on the surface of the guide wheel body 205, and the guide wheel body 205 rotates with the cable, serving to support it and reduce frictional resistance.

[0052] The drive assembly is used to drive the screws 203 on both sides to rotate synchronously, thereby causing the sliding block 204 to rise and fall, and then driving the guide wheel body 205 to rise and fall as a whole through the sliding block 204. Specifically, the drive assembly includes a dual-axis motor 206, a first worm 207, a second worm 209, a first worm wheel 208, and a second worm wheel. The dual-axis motor 206 is fixedly mounted on the base 1 via a support seat 210, and the two output ends of the dual-axis motor 206 are respectively connected to the first worm 207 and the second worm 209. The first worm 207 and the second worm 209 are rotatably connected to the base 1 via bearings 211 to ensure the stability of the worm rotation and reduce operating vibration. The bottom of the two screws 203 is fixed with the first worm wheel 208 and the second worm wheel, respectively, wherein the first worm wheel 208 meshes with the first worm 207, and the second worm wheel meshes with the second worm 209.

[0053] The worm and worm wheel together form the transmission structure. When the dual-axis motor 206 starts, its two output ends synchronously drive the first worm 207 and the second worm 209 to rotate. The first worm 207 and the second worm 209 respectively drive the first worm wheel 208 and the second worm wheel to rotate synchronously, thereby causing the two screws 203 to rotate synchronously. The two sliding blocks 204, threadedly connected to the screws 203, synchronously rise and fall along the vertical direction of the mounting shell 201, thereby driving the guide wheel body 205 to rise and fall as a whole while maintaining a horizontal state. Through the above structure, the height of the guide wheel body 205 can be quickly adjusted according to different construction environments and different cable laying heights. The synchronous drive method avoids the tilting of the guide wheel body 205 caused by unilateral lifting and lowering, improving the stability and synchronicity of the guide wheel height adjustment.

[0054] Furthermore, a drive motor 212 is fixedly mounted on one of the sliding blocks 204 via a mounting plate 216. The drive motor 212 is connected to the guide wheel body 205 via a pulley assembly and is used to drive the guide wheel body 205 to rotate actively. The drive motor 212 can be a servo motor to achieve more precise speed control. The pulley assembly includes a drive pulley 213, a driven pulley 214, and a belt 215. The drive pulley 213 is fixed on the output shaft of the drive motor 212, the driven pulley 214 is coaxially fixed to the guide wheel body 205, and the belt 215 is tensioned between the drive pulley 213 and the driven pulley 214. When the drive motor 212 starts, it drives the guide wheel body 205 to rotate actively via the pulley assembly, creating an active conveying effect between the guide wheel body 205 and the cable, thereby reducing cable dragging resistance, reducing friction and wear between the cable and the guide wheel body 205, and enabling the cable to be laid more smoothly and continuously.

[0055] II. Flattening Mechanism 3

[0056] like Figure 2 and Figure 3 As shown, the flattening mechanism 3 is installed on the top of the mounting housing 201 of the guide wheel assembly 2, directly above the guide wheel body 205, and is used to press the cable tightly against the guide wheel body 205 to prevent the cable from jumping, tilting or deviating during travel.

[0057] The flattening mechanism 3 includes two sets of linkage assemblies arranged symmetrically on the left and right sides. Each set of linkage assemblies includes a first linkage 301, a second linkage 302, a third linkage 303, and a pressure plate 304. The first end of the first linkage 301 is fixed to the top of the mounting housing 201, and the second end of the first linkage 301 is hinged to the first end of the second linkage 302. The second end of the second linkage 302 is hinged to the first end of the third linkage 303. The second end of the third linkage 303 is hinged to the pressure plate 304. The two pressure plates 304 are hinged together by a cross plate 305.

[0058] Here, the side of each pressure plate 304 closest to the horizontal plate 305 is defined as the inner side, and the side furthest from the horizontal plate 305 is defined as the outer side. When the pressure plate 304 is pressed down, the outer side of the pressure plate 304 is lower than the inner side, and the horizontal plate 305 remains horizontal. The two pressure plates 304 and the horizontal plate 305 together form a downward-opening limiting slot that is low at both ends, high in the middle, and flat. The cable is confined between this limiting slot and the guide wheel body 205, thereby effectively suppressing the cable's jumping, tilting, and lateral deviation during travel.

[0059] Each linkage assembly also includes a cylinder 306. The bottom end of the cylinder 306 is fixed to the mounting housing 201, and the top end of the cylinder 306 is hinged to the middle of the second linkage 302. Each linkage assembly preferably has two cylinders 306 arranged side by side to improve the stability of the clamping force. When the piston rod of the cylinder 306 extends or retracts, it drives the second linkage 302 to swing around its hinge point with the first linkage 301, which in turn drives the pressure plate 304 to press down or lift through the third linkage 303.

[0060] During the movement, the first link 301 limits and positions the second link 302, restricting the swing range of the second link 302, ensuring that the pressure plate 304 can accurately press against the cable surface, and improving the stability and repeatability of the flattening mechanism 3.

[0061] III. Guiding Mechanism 4

[0062] like Figure 4 As shown, the guide mechanism 4 is installed on the upper surface of the base 1, located in front of the guide wheel assembly 2 along the cable travel direction, and is used to provide initial guidance for the cable before it enters the guide wheel body 205.

[0063] The guide mechanism 4 includes two columns 401, which are fixed to the left and right sides of the upper surface of the base 1 and are arranged opposite to each other. Each column 401 is fixed with an inner bracket 402 and an outer bracket 403.

[0064] Each column 401 is fitted with a support arm 404, which can slide up and down along the axial direction of the column 401. An upper guide roller 405 is rotatably connected between two support arms 404, and the upper guide roller 405 can rotate freely around its own axis.

[0065] A lower guide roller 406 is rotatably connected between the two inner supports 402. The lower guide roller 406 is located directly below the upper guide roller 405, forming a gap between them for the cable to pass through. The inner supports 402 utilize their own rigid structure formed by bending to stably bear the vertical load transmitted by the cable, ensuring the coaxiality of the lower guide roller 406 and the stability of its support.

[0066] Each outer bracket 403 has a pressure plate 407 extending from its top, which is fixed to the top of the column 401. A spring 408 is fitted onto the top of the column 401, located between the pressure plate 407 and the support arm 404. Specifically, the lower end of the spring 408 abuts against the support arm 404, and the upper end abuts against the pressure plate 407. The preload of the spring 408 pushes downward through the support arm 404, creating an elastic clamping force between the upper guide roller 405 and the lower guide roller 406.

[0067] As the cable passes between the upper guide roller 405 and the lower guide roller 406, the guide rollers passively rotate with the cable, reducing frictional loss on the cable sheath. Under the elastic action of the spring 408, the upper guide roller 405 can float up and down, automatically adapting to fluctuations in the diameter of cables of different specifications and providing cushioning against protrusions at cable joints. The spring 408 continuously provides clamping force, keeping the cable relatively stable during travel, preventing lateral swaying to a certain extent, and effectively preventing cable detachment, thus improving the cable's operational stability before entering the guide roller body 205.

[0068] Furthermore, both ends of the upper guide roller 405 and the lower guide roller 406 are integrally formed with limit plates 409. The limit plates 409 are used to limit the lateral deviation of the cable on the guide rollers, prevent the cable from slipping off the end of the guide rollers, and further improve the safety and stability of the guide mechanism 4.

[0069] This embodiment also provides a method for using a photovoltaic power station cable laying device, the method including the following steps:

[0070] S1. Move the device to the target position in the cable laying path of the photovoltaic power station, such as a corner position. The device is positioned by the moving wheels 101 with braking function at the bottom of the base 1, and the brakes are locked to prevent the device from moving during operation. The cable is introduced into the guiding mechanism 4, where the upper guide roller 405 and the lower guide roller 406 form an elastic pressure clamp under the elastic action of the spring 408, which initially guides the cable and keeps it relatively stable during travel, preventing the cable from detaching or swinging significantly from side to side during traction.

[0071] S2. Based on the construction environment and laying height requirements, activate the drive assembly of the guide wheel assembly 2. The dual-axis motor 206 drives the first worm gear 207 and the second worm gear 209 to rotate synchronously, which in turn drives the first worm wheel 208 and the second worm wheel to rotate, causing the two screws 203 to rotate synchronously. The sliding block 204, threaded onto the screw 203, moves up and down synchronously along the mounting housing 201. Through the sliding block 204, the guide wheel body 205 is horizontally raised and lowered to the required height to adapt to cable laying requirements under different construction environments.

[0072] S3. Activate cylinder 306. The piston rod of cylinder 306 drives the second connecting rod 302 to swing, which in turn drives the pressure plate 304 to press down via the third connecting rod 303. After pressing down, the outer sides of the two pressure plates 304 are lower than the inner sides, forming a downward-opening limiting slot with the horizontal plate 305, which is low at both ends and high in the middle. This limits the cable to be positioned above the guide wheel body 205. With the cooperation of the limiting slot and the guide wheel body 205, the cable is centered and limited, effectively suppressing any jumping, tilting, or deviation that may occur during cable movement.

[0073] S4. Start the drive motor 212. The drive motor 212 drives the guide wheel body 205 to rotate actively through the pulley assembly. The guide wheel body 205 actively transports the cable, reduces the frictional resistance between the cable and the guide wheel body 205, and assists the cable to be laid smoothly and continuously.

[0074] During construction, this device can be deployed at different corner positions along the laying path according to the route requirements, so as to achieve a smooth, continuous, efficient and safe laying operation of photovoltaic power station cables along the entire laying path.

[0075] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
