Description

Technical Field

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

[0002] In the construction of photovoltaic power generation systems, in order to make full use of land resources and obtain better sunlight conditions, photovoltaic panels are often installed on ground with a certain slope. While this terrain selection helps to improve the efficiency of photovoltaic power generation, it also brings many challenges to the construction process.

[0003] In actual construction, the construction site is often sloping, which complicates the construction environment. When using cable laying racks for photovoltaic circuit cable laying, the racks need to be placed on these rugged slopes. However, existing cable laying racks are not designed to fully consider the needs of such special terrain.

[0004] Due to the unevenness and slope of the ramp, the cable laying frame has poor stability after placement. During the laying process, the uneven distribution of cable tension and the weight of the laying frame itself can easily cause displacement. Once the laying frame shifts, it not only affects the cable laying path, causing uneven laying and increasing construction difficulty, but it can also cause problems such as cable twisting and tangling, reducing cable quality and even requiring the laying operation to be redone, seriously affecting the construction progress and increasing construction costs.

[0005] Meanwhile, the cable-laying frame on the slope also poses a risk of tipping over. If the frame tipps over, it will not only damage itself but also pose a safety threat to nearby construction workers, potentially causing an accident and severely endangering their lives. Furthermore, a tipped-over frame could damage the cables, further affecting the normal operation of the photovoltaic power generation system. Summary of the Invention

[0006] This utility model provides a photovoltaic circuit cable laying frame to improve construction safety and construction quality.

[0007] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a photovoltaic circuit cable laying rack, including a base, a column disposed on the base, and a laying reel rotatably mounted on the column. The base is provided with a ground-gripping component for fixing the base to the ground; wherein the ground-gripping component includes:

[0009] Multiple support bases are disposed on the edge of the base and are evenly distributed around the circumference of the base, and each support base is provided with a hinge groove.

[0010] Multiple rotating blocks are rotatably installed in each of the hinge slots, and the surface of each rotating block is provided with threaded through holes;

[0011] Multiple gripping threaded rods are respectively assembled in each of the threaded through holes, and the lower end of each gripping threaded rod is a pointed part; wherein, each gripping threaded rod adjusts its gripping angle as each of the rotating blocks rotates.

[0012] Preferably, it further includes a leveling mechanism, which is disposed between the base and the column, and includes;

[0013] A support rod is fixed to the center of the base surface and located between the base and the column;

[0014] An adjusting ball is fixed to one end of the support rod near the column;

[0015] An adjusting block is fixed to one end of the column near the support rod, and the adjusting block rotates with the adjusting ball to adjust the tilt angle of the column relative to the base.

[0016] A support assembly is provided between the base and the cable reel to limit the relative position of the column and the base.

[0017] Preferably, the support component includes:

[0018] A support plate is located between the base and the wire feeding plate, and the support plate is fixedly connected to the adjusting block so as to rotate with the rotation of the adjusting block;

[0019] Multiple adjustable telescopic rods are evenly arranged along the circumferential direction of the support plate and connected between the support plate and the base;

[0020] Each of the adjustable telescopic rods has its two ends hinged to the support plate and the base, respectively, to adjust the tilt angle between the support plate and the base.

[0021] Preferably, the adjustable telescopic rod includes a threaded rod sleeve and a threaded rod, the threaded rod sleeve being threaded onto the threaded rod; the threaded rod sleeve and the threaded rod are respectively provided with connecting balls for hinge connection at their opposite ends, and the threaded rod is provided with an adjusting block.

[0022] Preferably, the adjustable telescopic rod is an electric telescopic rod.

[0023] Preferably, the pay-off reel is rotatably embedded with ball bearings, and the ball bearings abut against the support reel.

[0024] Preferably, the upper end of the gripping threaded rod is provided with a handle.

[0025] Preferably, the plurality of support bases are integrally formed with the base.

[0026] Preferably, the support base is detachably connected to the outer wall of the base to increase or decrease the number of support bases.

[0027] Preferably, the support base includes:

[0028] A connecting block is attached to the outer wall of the base;

[0030] Compared with the prior art, the advantages of this utility model are as follows:

[0031] (1) Enhance stability and ensure construction safety.

[0032] The base is equipped with a gripping component. The rotation of the rotating block drives the gripping threaded rod to adjust the gripping angle according to the actual ground conditions, so that the gripping threaded rods at different positions can penetrate the ground at different angles, enhancing the gripping effect and thus firmly fixing the base to the ground, preventing the cable laying frame from shifting or tipping over on the slope, and ensuring the safety of construction personnel.

[0034] By adjusting the angle of the wire-laying reel using a leveling mechanism, the reel can be made relatively horizontal on slopes, avoiding problems such as cable tangling and uneven wire laying caused by reel tilt. Furthermore, the support components in the leveling mechanism, including the support plate, adjustable telescopic rod, and connecting ball, further enhance stability and adjustment precision. In addition, the adjustable telescopic rod can be adjusted manually or electrically to precisely control the angle between the support plate and the column, thereby improving construction quality.

[0045] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] like Figure 1-6 As shown in the illustration, a photovoltaic circuit cable laying rack according to an embodiment of this utility model includes a base 1, a column 2, and a laying reel 3. The base 1 serves as the fundamental support component of the entire laying rack, providing an installation platform for the column 2 and the laying reel 3, ensuring the stability and integrity of the entire laying rack structure. The column 2 serves as the support component for the laying reel 3, enabling it to rotate stably and providing support and a fixed position for the laying operation. The laying reel 3 is used to hold the cable coil; rotation releases the cable, making it the core component for realizing the laying function.

[0047] The core idea of ​​this utility model embodiment is that by setting a ground gripping component 4 on the base 1, the base 1 has ground gripping ability, thereby adapting to ground with different inclination angles. Furthermore, while enabling the base 1 to grip the ground, the angle of the cable reel 3 can also be adjusted by the leveling mechanism 5, so that the cable reel 3 can be placed horizontally, avoiding problems such as cable tangling and poor cable feeding caused by the tilt of the cable reel 3.

[0048] The specific structure of each component in this embodiment will be described in detail below:

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, the base 1 is generally disc-shaped and is usually placed on the ground to be constructed. The gripping component 4 on the base 1 applies force to the base 1 to ensure the stability of the base 1.

[0050] Specifically, the gripping assembly 4 includes multiple support seats 41, multiple rotating blocks 42, and multiple gripping threaded rods 43. The support seats 41 are all located on the outer edge of the base 1 and are evenly distributed around the circumference of the base, thus ensuring uniform force distribution on the base 1 in all directions. For example, in this embodiment, six support seats 41 are used, with adjacent support seats 41 spaced 60° apart. In other embodiments, four support seats 41 can be used, with adjacent support seats 41 spaced 90° apart; the specific configuration can be adapted to meet specific needs.

[0051] like Figure 3 As shown, in this embodiment, the support base 41 includes a connecting block 411 and two lugs 412. The connecting block 411 is connected to the outer wall of the base 1, and the two lugs 412 are disposed opposite to each other at the end of the connecting block 411 away from the base, so that a hinge groove 413 is formed between the two lugs 412. Furthermore, in this embodiment, multiple support bases 41 are integrally formed with the base 1, thereby improving the overall structural strength. In another optional embodiment, each support base 41 can be detachably connected to the outer wall of the base 1 (e.g., by snap-fit ​​connection or bolt connection), thereby allowing the number of support bases 41 to be freely increased or decreased as needed to meet the usage requirements of different situations.

[0052] Continue to refer to Figure 3 As shown, the rotating block 42 is generally a square block and is rotatably mounted in the hinge groove 413 around the X direction. It can be understood that in this embodiment, the X direction is perpendicular to the line connecting the center of the base 1 and the center of the rotating block 42, and parallel to the surface of the base 1. Furthermore, the center of the rotating block 42 has a threaded through hole 421 along the Z direction, which is perpendicular to the surface of the rotating block 42 and perpendicular to the X direction.

[0053] The gripping threaded rod 43 is fitted into the threaded through hole 421 of the rotating block 42 for threaded engagement with the threaded through hole 421. Furthermore, the lower end of the gripping threaded rod 43 is a pointed tip 431, facilitating drilling into the muddy ground commonly encountered in photovoltaic construction; the upper end of the gripping threaded rod 43 is a handle 432, providing a point of leverage for construction workers and greatly facilitating the operation of the gripping threaded rod 43.

[0054] Understandably, by rotating the rotating block 42 around the X-direction, the gripping threaded rod 43 can adjust its gripping angle according to the actual ground conditions, allowing the tip 431 of the gripping threaded rod 43 to better contact and penetrate the ground, thereby firmly fixing the base 1 to the ground and preventing the cable laying frame from shifting or tipping over on the slope. Thus, the base 1 provides stable support for the column 2 and the cable laying reel 3, and the column 2 ensures the stable rotation of the cable laying reel 3, keeping the entire cable laying frame stable on the sloping ground. This avoids displacement or tipping caused by uneven ground and slope issues, providing a stable working platform for cable laying operations and improving the efficiency and safety of photovoltaic construction.

[0055] like Figure 1 As shown, in the above embodiment, preferably, the photovoltaic circuit cable laying rack further includes a leveling mechanism 5, which is disposed between the base 1 and the column 2 to realize the leveling operation of the laying reel 3. Specifically, as shown... Figure 4 As shown, the adjustment mechanism 5 includes a support rod 51, an adjusting ball 52, an adjusting block 53, and a support assembly 54. The support rod 51 is cylindrical, with its bottom fixed to the center of the base 1 surface and the adjusting ball 52 fixed to its top. The adjusting block 53 is disc-shaped and smaller than the base 1. The bottom of the adjusting block 53 has an arc-shaped groove 531 for rotating with the adjusting ball 52; the top of the adjusting block 53 is fixedly connected to the bottom of the column 2, so that the rotation of the adjusting block 53 can drive the column 2 to rotate, thereby adjusting the tilt angle of the column 2 relative to the base 1. This ensures that when the base 1 is on a slope, the column 2 remains vertical by adjusting its position. The support assembly 54 supports the column 2 between the base and the reel, limiting the relative position of the column 2 and the base 1 to prevent the column 2 from shifting due to gravity or other factors (e.g., wind).

[0056] Continue to refer to Figure 4 As shown, in this embodiment, the support assembly 54 specifically includes a support plate 541 and multiple adjustable telescopic rods 542. The support plate 541 is generally disc-shaped, with a size similar to the pay-off reel 3. The support plate 541 is located between the base 1 and the pay-off reel 3 and is fixedly connected to the adjusting block 53, allowing it to rotate synchronously with the angle adjustment of the adjusting block 53. Multiple adjustable telescopic rods 542 are evenly arranged along the circumferential direction of the support plate 541 and connected between the support plate 541 and the base 1. The two ends of each adjustable telescopic rod 542 are hinged to the support plate 541 and the base 1, respectively, to adjust the tilt angle between the support plate 541 and the base 1.

[0057] Understandably, the support plate 541 serves as an intermediate component connecting the adjusting block 53 and the adjustable telescopic rod 542, providing an installation position for the adjustable telescopic rod 542 and simultaneously linking the movement of the adjusting block 53 and the adjustable telescopic rod 542. When the adjusting block 53 rotates, the support plate 541 rotates synchronously with the angle adjustment of the adjusting block 53, thereby driving the adjustable telescopic rod 542 to perform corresponding length and angle adjustments to support the pay-off reel 3 and the column 2. Furthermore, the support plate 541 also provides a relatively stable support platform for the pay-off reel 3, helping to improve the stability of the pay-off reel 3.

[0058] Furthermore, the length of each adjustable telescopic rod 542 can be flexibly adjusted according to the actual condition of the slope and the needs of leveling, thereby precisely controlling the angle of the support plate 541 and the column 2 to achieve a more accurate leveling effect. During adjustment, multiple adjustable telescopic rods 542 can be adjusted simultaneously to prevent them from affecting each other. At the same time, the adjustable telescopic rods 542 provide stable support after leveling, preventing the support plate 34 and the column 12 from swaying.

[0059] like Figure 5 As shown, in the above embodiment, preferably, the adjustable telescopic rod 542 includes a threaded rod sleeve 5421 and a threaded rod 5422. The threaded rod sleeve 5421 is threaded onto the threaded rod 5422, and each end of the threaded rod sleeve 5421 and the threaded rod 5422, which are far apart from each other, is provided with a connecting ball 5423. The two connecting balls 5423 are hinged to the support plate 541 and the base 1 respectively, allowing the adjustable telescopic rod 542 to rotate in different directions to adapt to changes in the angle between the support plate 541 and the base 1. The hinged connection allows the adjustable telescopic rod 542 to freely adjust its angle during leveling, avoiding the limitation of leveling flexibility caused by a rigid connection.

[0060] In addition, an adjusting block 5424 is provided at the end of the threaded rod 5422 that contacts the connecting ball 5423. In this embodiment, the adjusting block 5424 is a hexagonal nut, which can be used with a wrench to rotate the adjusting block 5424 to drive the relative rotation between the threaded rod 5422 and the threaded rod sleeve 5421, thereby realizing the length adjustment of the adjustable telescopic rod 542.

[0061] It is understandable that the biggest advantage of this adjustable telescopic rod in this embodiment, composed of threaded rod sleeve 5421, threaded rod 5422, connecting ball 5423, and adjusting block 5424, is that it can be adjusted by manual rotation. In actual photovoltaic construction scenarios, the slope and terrain conditions vary, requiring flexible adjustments to the leveling of the cable-laying frame. Construction workers do not need complex tools and equipment; they can simply hold (or clamp) the adjusting block 5424 by hand and rotate it to precisely control the length of the adjustable telescopic rod 542 according to the actual situation.

[0062] In another alternative embodiment, the adjustable telescopic pole 542 can also be an electric telescopic pole to automate the leveling process. In photovoltaic construction scenarios, when encountering sloping terrain, construction workers no longer need to manually rotate each adjusting block to adjust the length of the telescopic pole. The electric telescopic pole, driven by a motor, can quickly and accurately change its length, significantly reducing the time required for leveling and improving construction efficiency. For example, in the construction of a large photovoltaic power station, leveling a single cable-laying frame might take several minutes or even longer using a manually adjustable telescopic pole; however, using an electric telescopic pole, the leveling operation can be completed in tens of seconds.

[0063] like Figure 6 As shown, in the above embodiment, preferably, the bottom of the pay-off reel 3 is rotatably fitted with a ball bearing 31, and the ball bearing 31 abuts against the support plate 541. Thus, the rolling cooperation between the ball bearing 31 and the support plate 541 can significantly reduce the friction force when the pay-off reel 13 rotates, making the pay-off reel 13 perform pay-off operations more smoothly.

[0064] The following details the specific usage process of the photovoltaic circuit cable laying frame in this embodiment:

[0065] ① After selecting a suitable slope location, perform simple ground preparation to ensure that base 1 is placed stably.

[0066] ② Rotate each rotating block 42 to drive each gripping thread rod 43 to find the optimal gripping angle, so that the gripping thread rod 43 located in the direction of ground slope is as close as possible to the direction of gravity, and the other gripping thread rods 43 are perpendicular to the ground; then, rotate the gripping thread rod 43 and use its tip 431 to drill into the ground to firmly fix the base 11, preventing the cable laying frame from shifting or tipping over.

[0067] ③ If a manually adjustable telescopic rod is used, the construction personnel need to clamp the adjusting block 53 and the threaded rod sleeve 5421 respectively, and then rotate the adjusting block 5424 so that the threaded rod sleeve 5421 and the threaded rod 5422 rotate relative to each other, thereby adjusting the overall length of the telescopic rod. If an electric telescopic rod is used, the construction personnel need to operate the control switch to adjust the telescopic rod to the appropriate length. Through the coordinated work of multiple adjustable telescopic rods 542, the support plate 541 is driven to change its angle, thereby adjusting the angles of the adjusting block 53, the column 2, and the pay-off reel 3 connected to the support plate 541. Furthermore, the adjusting ball 52 rotates within the adjusting block 53, providing the column 2 with the possibility of multi-angle adjustment, so that the column 2 and the pay-off reel 3 reach a relatively horizontal state, ensuring that the pay-off reel 3 is placed horizontally for convenient subsequent operations.

[0068] ④ Place the cable coil on the pay-off reel 3. Since the ball bearing 31 embedded in the pay-off reel 3 abuts against the support plate 541, the sliding friction is converted into rolling friction, which reduces the friction force when the pay-off reel 3 rotates, ensuring that the pay-off reel 3 can rotate easily and flexibly.

[0069] ⑤ Once everything was ready, the construction workers pulled the cables to begin laying them out.

[0070] Understandably, during the cable laying process, the cable laying reel 3 can rotate smoothly and continuously lay out the cable. The ground gripping component 4 ensures the stability of the base 1 and prevents the cable laying frame from shifting or tipping over due to cable tension; the leveling mechanism 5 maintains the horizontal state of the cable laying reel 3 to avoid problems such as cable twisting or tangling, ensuring that the cable laying work is efficient and smooth.
