[0028] Refer to Figure 1 , the present utility model provides a wire pay-off device, which is used in cooperation with a plurality of wire reels 3, and includes a bracket 1 and a wire guiding unit 5 corresponding to the wire reels 3. A wire leading unit 2 corresponding to the wire reels 3 is arranged on the bracket 1. Each wire guiding unit 5 includes a connecting member for fixing to the wire reel 3 and a wire guiding cylinder 505 rotatably connected to the connecting member. After the plurality of wire reels 3 are fixed to the corresponding connecting members, the wires on each wire reel 3 are payed off through the corresponding wire guiding cylinders 505 and the corresponding wire leading units 2. In this basic technical solution, the bracket 1 keeps the wire leading unit 2 at a certain distance from the ground. During the wire pulling process, a certain angle is formed between the ground and the cable on the wire reel 3, so that the cable is not easily dragged on the ground during the wire pay-off process. The wire guiding unit 5 is installed on the wire reel 3, and the cable can be payed off after passing through the wire guiding cylinder 505 and then through the wire leading unit 2. It is applicable to wire reels 3 of different specifications. At the same time, the cables of the plurality of wire reels 3 pass through the wire leading unit 2, enabling the plurality of wire reels 3 to pay off wires simultaneously.

[0029] It should be noted that the bracket 1, as the basic structure of the entire cable laying device, is used to carry and fix the lead unit 2. When working at night, a searchlight or other necessary devices can also be installed. The lead unit 2 is located on the bracket and keeps a certain distance from the ground to ensure that the cable will not contact the ground during the cable laying process, avoiding abrasion and damage. The cable reel 3 is a carrier for storing the cable to be laid. It exists when leaving the factory and can also be wound around a specific cable reel 3. For example, when operating in a wading area or on a rainy day, a corresponding waterproof cover is set, and the cable reel 3 is provided with a base to raise it a certain height from the ground. The crossover unit 5 can flexibly adjust the cable direction, improve the cable laying efficiency, and pass the cables of multiple cable reels 3 through the lead unit 2 at the same time, realizing the simultaneous cable laying of multiple cables and improving the construction efficiency. This design can be applied to cable reels 3 of different specifications, making the cable laying device more general and reducing the situation of replacing the device due to changing the cable reel specifications. The lead unit 2 keeps a certain distance from the ground, effectively preventing the damage caused by the friction between the cable and the ground during the cable laying process, extending the service life of the cable. The connection between the cable reel and the cable laying device can be completed through simple assembly, reducing the operation difficulty, and even non-professional personnel can quickly master the usage method. The crossover cylinder 505 and the cable reel 3 are rotationally connected, and the cable direction can be adjusted according to actual needs, improving the flexibility during the cable laying process.

[0030] In addition, this cable laying device improves the cable laying efficiency and reduces cable damage, which can reduce the overall cost of the engineering project in the long run. This cable laying device is particularly suitable for large-scale cable laying work in the construction of photovoltaic power stations. During the construction of a photovoltaic power station, a large number of cables need to be laid to connect devices such as photovoltaic panels, inverters, and busbar boxes. Using this cable laying device can greatly simplify the cable laying process, reduce the consumption of manpower and material resources, and at the same time ensure the integrity of the cables, ensuring the stable operation of the photovoltaic power station.

[0031] In some embodiments, the lead unit 2 includes at least one strap 203 connected to the bracket 1 and a guide wheel 201 suspended on the strap 203. By setting multiple lead units 2 corresponding to the number of cable reels 3, each lead unit 2 is located directly above the cable reel 3, facilitating the passage of the cable through the lead unit 2 and helping to reduce the entanglement or misalignment of the cable during the cable laying process, reducing the construction risk and ensuring the safety of workers. The strap 203 makes the angle between the lead unit 2 and the bracket 1 not fixed, and the lead unit 2 can rotate or shift to a certain extent according to the different angles of the force direction, improving the flexibility during the cable laying process and being able to better adapt to complex construction environments.

[0032] In some embodiments, the guiding wheel 201 is provided with at least two wire grooves which are arranged along the circumferential side of the guiding wheel 201. One of the wire grooves is used for the guiding wheel 201 to place the binding strap 203 and connect with the bracket 1, which is convenient for installation and the connection relationship is more firm. The wire grooves of the guiding wheel 201 enable the movement of the cable to form a certain predetermined trajectory, avoiding damage to the cable during the cable laying process. The size specifications of the wire grooves are selected according to the diameter of the cable on the cable reel 3 to facilitate the cable to pass through the guiding wheel.

[0033] In some embodiments, a plurality of guiding wheels 201 are suspended on each binding strap 203. The number of guiding wheels 201 corresponds to the number of cable reels and is used for cable laying. By installing a plurality of guiding wheels 201 on each binding strap 202 to guide multiple cables, simultaneous cable laying of multiple cables can be achieved without waiting for one cable reel 3 to finish laying the cable and then laying the cable for other cable reels 3, which can improve the construction efficiency. Moreover, the cable laying device with multiple guiding wheels 201 can adapt to cables of different specifications, including differences in diameter, material, etc., improving the versatility and adaptability of the device. In addition, by adjusting the number and position of the guiding wheels 201, cables of different widths can be adapted to ensure that the cables can pass through smoothly, avoiding cable twisting or damage caused by sudden direction changes. The installation and disassembly of the guiding wheels 201 are relatively simple, which enables the construction team to quickly adjust the device to adapt to different cable laying requirements. The number of guiding wheels 201 can be increased or decreased or the position can be adjusted according to actual needs, making the device more adaptable to changes in site conditions. A faster cable laying speed means that the construction can be completed faster, reducing the construction time and labor costs.

[0034] In some embodiments, the bracket 1 includes a plurality of vertical rods 103. The adjacent vertical rods 103 are connected by a cross bar 104. A wire guiding unit 2 is installed on the cross bar 104. By splicing the vertical rods 103 and the cross bar 104, a stable frame structure is formed, improving the structural stability of the bracket 1 and enabling it to better resist the influence of external factors such as wind force and gravity, ensuring that the bracket 1 does not deform or displace. The wire guiding unit 2 installed on the cross bar 104 guides the cables of multiple cable reels 3 at the same time, improving the construction efficiency. The wire guiding unit 2 can be installed at different positions on the cross bar 104 according to actual needs to adapt to different numbers and specifications of cable reels. The bracket 1 can be appropriately adjusted according to the changes in the terrain to ensure that the cable laying device can work under various terrain conditions. The vertical rods 103 and the cross bar 104 are convenient for maintenance and disassembly, enabling the quick installation of the cable laying device and also being beneficial to the transportation and storage of the cable laying device. In addition, the vertical rods 103 are set to be adjustable in length to facilitate adjusting the distance between the wire guiding unit 2 and the ground and avoid the cables from dragging on the ground.

[0035] In some embodiments, a base 101 is installed at one end of each vertical rod 103 away from the cross bar 104, which facilitates the connection between the vertical rod 103 and the ground. At the same time, the base 101 increases the contact area between the vertical rod 103 and the ground, thereby providing a more stable support for the bracket 1, helping to resist external forces such as wind force and gravity, reducing the risk of the bracket tilting or collapsing due to external factors, ensuring the stability of the entire bracket 1 during the wire laying process. The use of the base 101 enables the vertical rod 103 to be quickly and accurately connected to the ground, facilitating the rapid erection of the wire laying equipment. The structure of the base 101 is appropriately adjusted according to different ground conditions. For example, a base 101 with a large bottom area is used on soft ground to disperse the weight and prevent the vertical rod from sinking, affecting the normal wire laying of the equipment; a pointed base 101 is used on hard ground to increase stability. The base 101 helps to increase the structural stability of the bracket 1 and improves the safety during the construction process. In addition, casters are provided on the base, enabling the wire laying equipment to move and facilitating flexible position adjustment at the construction site.

[0036] In some embodiments, through holes are provided on the base 101, and pipe fittings 102 are provided at the through holes. The vertical rod 103 is installed inside the pipe fittings 102. The use of the pipe fittings 102 enables the vertical rod 103 to be quickly and accurately connected to the base 101, facilitating the rapid erection of the wire laying equipment. The vertical rod 103 passes through the through hole and is installed inside the pipe fittings 102 to provide a firm connection, ensuring a tight and reliable connection between the vertical rod 103 and the base 101. By adjusting the insertion depth of the vertical rod 103 inside the pipe fittings 102, the height of the vertical rod 103 is adjusted, thereby changing the height of the cross bar 104 from the ground to meet different construction requirements. The pipe fittings 102 enable the vertical rod 103 to have a larger contact area with the base 101, thereby providing a more stable support, ensuring the stability of the entire bracket 1 during the wire laying process, avoiding damage caused by the shaking of the bracket 1 during the wire laying process, and at the same time reducing the risk of the bracket 1 collapsing, improving the safety during the construction process. In addition, the vertical rod 103 can pass through the through hole and be inserted into the ground. It should be noted that pipe fittings 102 with a sealed bottom are used on soft ground to prevent the vertical rod from sinking and ensure the stable operation of the equipment.

[0037] In some embodiments, multi-way pipe fittings 105 are provided at both ends of the cross bar 104. The multi-way pipe fittings 105 can ensure a firm connection between the cross bar 104 and other cross bars 104 or vertical rods 103, improving the stability of the entire bracket 1. The multi-way pipe fittings 105 make the connection between the cross bar 104 and the vertical rod 103 simpler and faster, facilitating the rapid erection of the wire laying equipment, facilitating the adjustment of the position or quantity of the cross bar 104, and expanding or shortening the size of the bracket 1 to meet the needs of different working conditions. In addition, the multi-way pipe fittings 105 are provided with installation holes to fit with the telescopic bosses formed by the cross bar 104 or the vertical rod 103 as an auxiliary connection, and then a locking member is used to reinforce the connection between it and the cross bar 104 or the vertical rod 103.

[0038] In some embodiments, the connecting member includes a bottom plate 501 for mounting on the wire reel 3 and a first rod member 502. One end of the first rod member 502 is connected to the bottom plate 501, and the other end is connected to the wire guiding cylinder 505 through a rotating member 503. The rotating member 503 enables the second rod member 504 to rotate during the wire paying-off process, causing the wire guiding cylinder 505 to rotate around the circumferential side of the wire reel 3, so that the cable is smoothly paid off from the wire reel 3, improving the efficiency of the wire paying-off process. The rotation of the wire guiding cylinder 505 can reduce the friction between the cable and the wire guiding cylinder 505, preventing wear on the cable. The cable can be protected by providing a flexible wear-resistant protective layer on the part of the wire guiding cylinder 505 in contact with the cable. The bottom plate 501 enables the wire guiding unit 5 to be quickly connected to the wire reel 3, and the connection between the bottom plate 501 and the wire reel 3 provides a stable support, ensuring the stability of the wire guiding unit 5 during the wire paying-off process.

[0039] In some embodiments, a second rod member 504 is provided on the rotating member 503. One end of the second rod member 504 away from the rotating member 503 is rotatably connected to the wire guiding cylinder 505, and the wire guiding cylinder 505 swings or rotates around the axis of the second rod member 504. As the position of the cable on the wire reel 3 changes, a certain angle will be formed between the cable and the wire guiding cylinder 505. The ability of the wire guiding cylinder 505 to adaptively swing or rotate around the second rod member 504 according to the change of this angle helps to reduce the jamming phenomenon of the cable during the wire paying-off process, ensuring that the cable is smooth and unobstructed during the wire paying-off process. The rotation of the wire guiding cylinder 505 reduces the friction between the cable and the wire guiding cylinder 505, reduces the wear of the cable during the wire paying-off process, and at the same time improves the efficiency of wire paying-off. In addition, it enables the wire guiding unit 5 to adapt to the cable distribution on the wire reel 3, improving the adaptability of the equipment.

[0040] To better understand the technical solution of the present invention, the following description is made in combination with relatively preferred technical features.

[0041] See Figure 1, the present utility model provides a wire paying-off device, which is used in cooperation with two wire reels 3, and includes a bracket 1 and a wire-crossing unit 5 arranged corresponding to the wire reels 3. The bracket 1 includes two vertical rods 103 with a diameter of 20 - 21 mm and a length of 1500 - 1700 mm. The adjacent vertical rods 103 are connected by a cross bar 104 with a diameter of 20 - 21 mm and a length of 1600 - 2000 mm. A wire guiding unit 2 is installed on the cross bar 104. The wire guiding unit 2 includes two straps 203 connected to the bracket 1 and a guide wheel 201 hoisted on the straps 203. The guide wheel 201 is provided with two wire grooves, and the wire grooves are arranged along the circumferential side of the guide wheel 201. One end of the vertical rod 103 away from the cross bar 104 is installed with a base 101, and the base 101 is a channel steel with a length of 1200 - 1300 mm. A through hole is provided on the base 101, and a pipe fitting 102 is provided at the through hole. The pipe fitting 102 has a diameter of 25 - 26 mm and a length of 150 - 250 mm. The vertical rod 103 is installed inside the pipe fitting 102. Both ends of the cross bar 104 are respectively provided with multi-way pipe fittings 105, and the diameters of the ports of the multi-way pipe fittings 105 can be selected according to the cross bar 104 or the vertical rod 103 to be connected. For example, the diameter of the cross bar 104 to be connected is 20 mm, and the diameter of the vertical rod is 20.5 mm. Therefore, the diameters of the multi-way pipe fittings 105 selected are 20.1 mm and 20.6 mm to adapt to connecting the cross bar 104 and the vertical rod 103. The wire-crossing unit 5 includes a bottom plate 501 for fixing with the wire reel 3, a first rod member 502, and a rotating member 503. One end of the first rod member 502 is connected to the bottom plate 501, and the other end is connected to the rotating member 503. A second rod member 504 is provided on the rotating member 503, and a wire-crossing cylinder 505 is installed at the end of the second rod member 504 away from the rotating member 503. The wire-crossing cylinder 505 is rotatably connected to the second rod member 504, and the wire-crossing cylinder 505 swings or rotates around the axis of the second rod member 504;

[0042] The assembly process of the wire laying device includes: placing the base 101 on a flat and compacted ground, directly inserting the vertical rod with the multi-way pipe fitting 105 into the pipe fitting 102, and then inserting the cross bar 104 into the multi-way pipe fitting 105. Assemble the bracket 1 according to this method. Fix the guide wheel 201 on the cross bar 104 through the tie strap 203, and the fixed position is determined according to the position of the wire reel 3 below. The rotating part 503 uses a bearing with an inner diameter of 20 - 30 mm. The diameter of the first rod is 20 - 50 mm, and the length is 200 - 500 mm. The size of the bottom plate 501 is selected according to the specification of the wire reel. Weld the first rod 502 to the rotating part 503, and then weld the first rod 502 to the connecting bottom plate 501. The rotating part 503 is connected to the second rod 504, and a wire crossing cylinder 505 is welded to the end of the second rod 504 away from the rotating part 503. After the wire crossing unit 5 on the wire reel 3 is installed, pass the cable on the wire reel 3 through the wire crossing cylinder 505 and the guide wheel 201. When the wire laying operator applies an external force to pull, the cable drives the wire crossing cylinder 505 to rotate around the circumferential side of the wire reel 3 under the stress state, and makes the wire crossing cylinder 505 swing or rotate around the axis of the second rod 504, realizing the wire laying function.

[0043] The above solution has the following advantages. The bracket 1 makes the guide wheel 201 at a certain distance from the ground. During the wire pulling process, a certain angle is formed between the ground and the cable on the wire reel 3, making it difficult for the cable to drag on the ground during the wire laying process. Connect the bottom plate 501 to the wire reel 3, and the cable can be laid after passing through the wire crossing cylinder 505 and then through the guide wheel 201. It is applicable to wire reels 3 of different specifications. At the same time, passing the cables of multiple wire reels 3 through the corresponding guide wheels 201 can realize the simultaneous wire laying of multiple wire reels 3.
