Description

Technical Field

[0001] The utility model relates to the technical field of cable pay-off, in particular to a portable cable pay-off supporting device. Background Art

[0002] During the electrical installation process of a photovoltaic power generation project, DC cable payout plays a crucial role. The speed of payout directly impacts the efficiency of the PV string DC cable installation, and thus the overall progress of the PV string's commissioning. However, the DC cable payout process presents a series of technical challenges.

[0003] First, the insulation layer of DC cables is easily damaged during the unwinding process. Because the cable's insulation is relatively thin and its wire diameter is small, it is easily scratched by external factors such as thorns and sharp objects on the ground during the unwinding process. This damage not only reduces the insulation resistance but also affects the cable's insulation performance, thereby affecting the normal power generation of the PV panels. Once the insulation layer is damaged, the PV strings may malfunction during power generation, resulting in financial losses and the need to replace the cables, increasing construction costs and time.

[0004] Secondly, the DC cables for photovoltaic strings are divided into positive and negative poles and typically consist of two cables, commonly known as the "red and black wires." During the payout process, these two cables must be paid out simultaneously. However, traditional payout methods often rely on manual dragging, which can easily cause the red and black wires to become tangled when dragged on the ground. This not only affects payout progress but can also cause additional damage to the cables.

[0005] Furthermore, due to the temporary, mobile nature of various equipment at photovoltaic power generation project construction sites, and the large work areas involved, laying out DC cables in photovoltaic projects is currently primarily done manually. This method results in significant labor waste in centralized photovoltaic projects. Due to the large size of the photovoltaic site, the large number of photovoltaic strings, and the fact that maintenance roads are typically planned only to the box-type transformers, most photovoltaic strings are located far from the DC cable reels. Consequently, the laying-out process requires additional personnel to pull the cables. This not only increases the number of personnel on the team but also complicates the transition between laying out and installation. The workload for on-site electrical workers is heavy, and installation speed is affected by the staffing of the electrical team. Considering the overall cost, installation efficiency is relatively low.

[0006] In summary, the traditional manual laying-out method for photovoltaic DC cables has numerous drawbacks, including labor waste, vulnerability to cable insulation damage, and tangling of red and black cables. These issues severely restrict the efficiency and quality of photovoltaic string DC cable installation, necessitating improvements and innovations in DC cable laying. Therefore, the design of a portable cable laying support device is crucial for improving the construction efficiency and economic benefits of photovoltaic power generation projects.

[0028] Example 1:

[0029] See attached Figures 1 to 4 The utility model discloses a portable cable laying support device, such as Figure 1 As shown, it includes a column 1, a support component 2 and an insertion component 3. The axis of the column 1 extends in the up-down direction to provide support for the entire device. The support component 2 is rotatably connected to the column 1 and is coaxially arranged with the column 1. It can flexibly rotate as the cable is pulled during the unwinding process. Specifically, Figure 2 As shown, the support component 2 includes a circular tube 21 that is sleeved on the column 1 and at least one circular disc 22 connected to the circular tube 21. The circular disc 22 and the circular tube 21 are arranged coaxially, together forming two support positions for supporting the cables. The red and black DC cables are placed on the two support positions, with the circular tube 21 as the dividing line. This ensures that the cables remain separated during the pay-out process, effectively preventing the occurrence of cable entanglement. The insertion component 3 is fixedly connected to the lower end of the column 1. The lower end of the insertion component 3 can be designed to have a sharp shape to facilitate the insertion of the column 1 into the ground and achieve stable fixation of the device.

[0030] By designing a column 1 that can be inserted into the ground and a rotatably connected support component 2, the cable pay-out support device of the utility model can stably support the cable, effectively preventing the cable from directly contacting the ground or other sharp objects during the pay-out process, thereby greatly reducing the risk of damage to the cable insulation layer; at the same time, the support component 2 is designed with two support positions for supporting the cable, and can also ensure that the red and black wires remain separated during the pay-out process, effectively avoiding the occurrence of wire entanglement.

[0031] Example 2:

[0032] See attached Figures 1 to 4 Based on the first embodiment, in one embodiment of the present application, the support component 2 further includes bearings 23. Two bearings 23 can be provided, one at each end of the circular tube 21 and sleeved onto the column 1, such that the circular tube 21 and the column 1 are rotationally connected via the bearings 23. For example, the bearings 23 can be rolling bearings. This design further improves the rotational flexibility and stability of the support component 2, making the pay-off process smoother.

[0033] In one embodiment of the present application, support member 2 is height-adjustably mounted on column 1. Specifically, column 1 is designed as a threaded column with a threaded surface. Fastening nuts 4 are provided at each end of support member 2. Fastening nuts 4 match the threaded structure of column 1. By rotating fastening nuts 4, the height of support member 2 on column 1 can be adjusted.

[0034] In one embodiment of the present application, a protective tube 5 is further provided between the support component 2 and the fastening nut 4 located at the lower end thereof, which is used to prevent the cable from falling during the unwinding process, thereby improving the safety of the unwinding process. The height of the protective tube 5 relative to the column 1 is also adjustable. Specifically, the column 1 is provided with a through hole penetrating its side wall, and the protective tube 5 is connected to the column 1 through the through hole. By adjusting the position of the fastening nut 4 on the column 1, the height of the protective tube 5 can be conveniently adjusted to meet the requirements of unwinding cables of different lengths, further enhancing the flexibility and adaptability of the device. Figure 2 As shown, the protection tube 5 may be an inverted U-shaped structure.

[0035] In one embodiment of the present application, a gasket 6 is provided between the bearing 23 and the protective tube 5 to reduce friction and wear and increase the service life of the device. The material of the gasket 6 can be selected according to actual needs, such as metal, plastic, etc.

[0036] Example 3:

[0037] See attached Figures 1 to 4 Based on the second embodiment, in one embodiment of the present application, Figure 4 As shown, the insertion component 3 includes an insertion rod 31, the upper end of which is threadedly connected to the column 1 and the lower end of which has a spike portion for easy insertion into the ground. The spike portion can be a reinforcement steel nail. The insertion component 3 also includes a force application rod 32, which is fixedly connected to the insertion rod 31 and has an inverted L shape. This facilitates construction workers to apply force to insert the device into the ground, improving the stability and practicality of the insertion component 3.

[0038] In one embodiment of the present application, a crossbar 7 is fixedly connected to the upper end of the column 1. The crossbar 7 can be an operating handle to facilitate operation by construction workers. The material and length of the crossbar 7 can be selected and designed according to actual needs.

[0039] The utility model provides a portable cable pay-off support device, the working process of which is as follows:

[0040] First, on the path where the photovoltaic panel DC cable needs to be laid, the location for placing the cable pay-out support device is pre-planned according to actual needs and cable length. Next, the construction personnel carry the cable pay-out support device to the predetermined position and insert it directly into the ground through the insertion component 3. At the same time, another right-angled force rod 32 extending next to the column 1 can be used to allow the construction personnel to step on it when inserting the column 1, thereby more easily inserting the column 1 into the ground and ensuring the stability of the pay-out device. Then, according to the actual conditions on site, the construction personnel can also adjust the height of the cable pay-out support device. After adjusting the height, the construction personnel place the red and black DC cables on the two support positions of the support component 2 of the cable pay-out support device respectively. During the entire pay-out process, the red and black DC cables can be pulled in sequence.
