[0030] See also Figure 1 The present invention provides a wire-releasing device, which is used in conjunction with a plurality of wire reels 3, and includes a bracket 1 and a wire-crossing unit 5 corresponding to the wire reels 3. The bracket 1 is provided with a wire-leading unit 2 corresponding to the wire reels 3. Each wire-crossing unit 5 includes a connector for fixing the wire reels 3 and a wire-crossing barrel 505 rotatably connected to the connector, so that after the plurality of wire reels 3 are fixed with the corresponding connector, the wires on each wire reel 3 are released through the corresponding wire-crossing barrel 505 and the corresponding wire-leading unit 2. In this basic technical solution, the bracket 1 allows the wire-leading unit 2 to be at a certain distance from the ground, and during the wire-pulling process, the ground and the cables on the wire reels 3 form a certain angle, so that the cables are not easy to drag on the ground during the wire-releasing process. The wire-crossing unit 5 is installed on the wire reel 3, and the cables first pass through the wire-crossing barrel 505 and then through the wire-leading unit 2 to release the wires. It is suitable for wire reels 3 of different specifications. At the same time, the cables of the plurality of wire reels 3 are passed through the wire-leading unit 2, so that the wire-releasing of the plurality of wire reels 3 can be realized at the same time.

[0031] It should be noted that the bracket 1 serves as the basic structure of the entire wire-laying equipment, and is used to carry and fix the lead unit 2. When working at night, a searchlight or other equipment that needs to be used can also be installed. The lead unit 2 is located on the bracket, keeping a certain distance from the ground to ensure that the cable does not touch the ground during the wire-laying process to avoid wear and damage. The wire reel 3 is a carrier for storing the cables to be laid. It exists at the factory and can also be wound on a specific wire reel 3. For example: when working in a wading area or on a rainy day, a corresponding waterproof cover is set, and a base is set on the wire reel 3 to raise it to a certain height from the ground. The wire crossing unit 5 can flexibly adjust the direction of the cable, improve the wire-releasing efficiency, and pass the cables of multiple wire drums 3 through the lead-in unit 2 at the same time, so as to realize the simultaneous wire-releasing of multiple cables and improve the construction efficiency. The design can be applied to wire drums 3 of different specifications, making the wire-releasing equipment more universal and reducing the need to replace the equipment due to changing the specifications of the wire drums. The lead-in unit 2 maintains a certain distance from the ground, which effectively prevents the damage caused by the friction between the cable and the ground during the wire-releasing process and prolongs the service life of the cable. The connection between the wire drum and the wire-releasing equipment can be completed through simple assembly, which reduces the difficulty of operation. Even non-professionals can quickly master the method of use. The wire crossing cylinder 505 and the wire drum 3 are connected in a rotating manner, and the direction of the cable can be adjusted according to actual needs, thereby improving the flexibility of the wire-releasing process.

[0032] In addition, the wire-laying equipment improves wire-laying efficiency and reduces cable damage, which can reduce the overall cost of the project in the long run. This wire-laying equipment is particularly suitable for large-scale cable laying work in photovoltaic power station construction. During the construction of photovoltaic power stations, a large number of cables need to be laid to connect photovoltaic panels, inverters, junction boxes and other equipment. The use of this wire-laying equipment 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.

[0033] In some embodiments, the lead unit 2 includes at least one strap 203 connected to the bracket 1 and a guide wheel 201 hoisted on the strap 203. By setting a plurality of lead units 2 corresponding to the number of wire reels 3, each lead unit 2 is located directly above the wire reel 3, which facilitates the passage of cables through the lead unit 2 and helps reduce cable entanglement or misalignment during the wire laying process, thereby reducing construction risks and ensuring the safety of workers. The strap 203 makes the angle between the lead unit 2 and the bracket 1 not fixed. The lead unit 2 can rotate or shift to a certain extent according to the different angles of the force direction, thereby improving the flexibility of the wire laying process and being able to better adapt to complex construction environments.

[0034] In some embodiments, the guide wheel 201 is provided with at least two wire grooves, which are arranged along the circumference of the guide wheel 201. One of the wire grooves is used for placing the binding strap 203 on the guide wheel 201 to connect it with the bracket 1, which is convenient for installation and provides a more secure connection. The wire groove of the guide wheel 201 allows the movement of the cable to form a certain predetermined trajectory to avoid damage to the cable during the laying process. The size of the wire groove is selected according to the diameter of the cable on the cable drum 3 to facilitate the cable to pass through the guide wheel.

[0035] In some embodiments, a plurality of guide wheels 201 are suspended on each binding belt 203, and the number of guide wheels 201 corresponds to the number of cable drums, which are used for laying out cables. By installing a plurality of guide wheels 201 on each binding belt 202 to guide a plurality of cables, the laying out of multiple cables can be achieved simultaneously, and there is no need to wait for the laying out of a cable drum 3 before laying out other cable drums 3, which can improve the construction efficiency, and the laying out equipment with a plurality of guide wheels 201 can adapt to cables of different specifications, including differences in diameter, material, etc., which improves the versatility and adaptability of the equipment. In addition, by adjusting the number and position of the guide wheels 201 to adapt to cables of different widths, it is ensured that the cables can pass smoothly, and the cable twisting or damage caused by sudden changes in direction is avoided. The installation and removal of the guide wheels 201 are relatively simple, which allows the construction team to quickly adjust the equipment to adapt to different laying out requirements. The number of guide wheels 201 is increased or decreased or the position is adjusted according to actual needs, so that the equipment can be more adaptable to changes in site conditions. A faster laying out speed means that the construction can be completed faster, reducing construction time and labor costs.

[0036] In some embodiments, the support 1 includes a plurality of vertical poles 103, and adjacent vertical poles 103 are connected by a cross bar 104. A lead unit 2 is installed on the cross bar 104. The vertical poles 103 and the cross bar 104 are spliced ​​to form a stable frame structure, which improves the structural stability of the support 1, can better resist the influence of external factors such as wind and gravity, and ensure that the support 1 does not deform or displace. The lead unit 2 installed on the cross bar 104 guides the cables of multiple cable drums 3 at the same time, which improves the construction efficiency. According to actual needs, the lead unit 2 can be installed at different positions of the cross bar 104 to adapt to cable drums of different numbers and specifications. The support 1 can be appropriately adjusted according to the changes in the terrain to ensure that the wire laying equipment can work under various terrain conditions. The vertical poles 103 and the cross bar 104 are easy to maintain and disassemble, making the installation of the wire laying equipment quick and convenient, and also conducive to the transportation and storage of the wire laying equipment. In addition, the vertical poles 103 are set to be adjustable in length, which is convenient for adjusting the distance between the lead unit 2 and the ground to avoid the cable dragging on the ground.

[0037] In some embodiments, a base 101 is installed at one end of each upright pole 103 away from the cross bar 104, which is convenient for the upright pole 103 to be connected to the ground. At the same time, the base 101 increases the contact area between the upright pole 103 and the ground, thereby providing a more stable support for the bracket 1, helping to resist the influence of external forces such as wind and gravity, reducing the risk of the bracket tilting or collapsing due to external factors, and ensuring that the entire bracket 1 remains stable during the line laying process. The use of the base 101 allows the upright pole 103 to be quickly and accurately connected to the ground, facilitating the rapid construction of the line 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 to prevent the upright pole from sinking and affecting the normal line 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 set on the base to enable the line laying equipment to be movable, which is convenient for flexible position adjustment at the construction site.

[0038] In some embodiments, a through hole is provided on the base 101, and a pipe fitting 102 is provided at the through hole. The vertical pole 103 is installed in the pipe fitting 102. The use of the pipe fitting 102 enables the vertical pole 103 to be quickly and accurately connected to the base 101, which is convenient for the rapid construction of the wire-laying equipment. The vertical pole 103 is installed in the pipe fitting 102 through the through hole to provide a firm connection, ensuring that the connection between the vertical pole 103 and the base 101 is tight and reliable. By adjusting the insertion depth of the vertical pole 103 in the pipe fitting 102, the height of the vertical pole 103 is adjusted, thereby changing the height of the cross bar 104 from the ground to adapt to different construction requirements. The pipe fitting 102 makes the contact area between the vertical pole 103 and the base 101 larger, thereby providing more stable support, ensuring that the entire bracket 1 remains stable during the wire-laying process, avoiding damage to the bracket 1 due to shaking during the wire-laying process, and reducing the risk of collapse of the bracket 1, thereby improving safety during the construction process. In addition, the vertical pole 103 can be inserted into the ground through the through hole. It should be noted that the bottom sealed pipe 102 is used on the soft ground to prevent the vertical pole from sinking, thereby ensuring the smooth operation of the equipment.

[0039] In some embodiments, a multi-way pipe fitting 105 is provided at both ends of the crossbar 104. The multi-way pipe fitting 105 can ensure a stable connection between the crossbar 104 and other crossbars 104 or vertical poles 103, thereby improving the stability of the entire bracket 1. The multi-way pipe fitting 105 makes the connection between the crossbar 104 and the vertical poles 103 easier and faster, facilitating the rapid construction of the wire-laying equipment, facilitating the adjustment of the position or number of the crossbar 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 fitting 105 is provided with a mounting hole to match the retractable boss formed by the crossbar 104 or the vertical pole 103 as an auxiliary connection, and then a locking piece is used to reinforce the connection between it and the crossbar 104 or the vertical pole 103.

[0040] In some embodiments, the connecting member includes a base plate 501 and a first rod 502 for installation on the wire drum 3. One end of the first rod 502 is connected to the base plate 501, and the other end is connected to the wire drum 505 through a rotating member 503. The rotating member 503 causes the second rod 504 to rotate during the wire release process, causing the wire drum 505 to rotate around the side of the wire drum 3, so that the cable is smoothly released from the wire drum 3, thereby improving the efficiency of the wire release process. The rotation of the wire drum 505 can reduce the friction between the cable and the wire drum 505, and prevent wear on the cable. The cable can be protected by providing a flexible wear-resistant protective layer at the part where the wire drum 505 contacts the cable. The base plate 501 allows the wire transfer unit 5 to be quickly connected to the wire drum 3. The connection between the base plate 501 and the wire drum 3 provides a stable support, thereby ensuring the stability of the wire transfer unit 5 during the wire release process.

[0041] In some embodiments, a second rod 504 is provided on the rotating member 503, and one end of the second rod 504 away from the rotating member 503 is rotatably connected to the wire drum 505, and the wire drum 505 swings or rotates around the axis of the second rod 504. As the position of the cable on the reel 3 changes, a certain angle is formed between the cable and the wire drum 505. The wire drum 505 can adaptively swing or rotate around the second rod 504 according to the change of this angle, which helps to reduce the jamming of the cable during the wire paying out process and ensure that the cable is smooth and unobstructed during the wire paying out process. The rotation of the wire drum 505 reduces the friction between the cable and the wire drum 505, reduces the wear of the cable during the wire paying out process, and improves the efficiency of the wire paying out. In addition, the wire drum unit 5 can adapt to the distribution of cables on the reel 3, thereby improving the adaptability of the equipment.

[0042] On the other hand, the present invention provides a method for using a wire-paying device, which uses the above-mentioned wire-paying device. The method includes the following steps: connecting the bottom plate 501 of the wire-crossing unit 5 with the corresponding wire drum 3, and then passing the wire of the wire drum 3 through the corresponding wire-crossing barrel 505 and the corresponding guide wheel 201 in sequence for wire-paying.

[0043] In order to better understand the technical solution of the present invention, the following is a description in combination with relatively preferred technical features.

[0044] See also Figure 1The present invention provides a wire-laying device, which is used in conjunction with two wire drums 3, and includes a bracket 1 and a wire-crossing unit 5 arranged corresponding to the wire drums 3. The bracket 1 includes two vertical poles 103, the diameter of the vertical poles 103 is 20-21mm, and the length is 1500-1700mm. Adjacent vertical poles 103 are connected by a cross bar 104, the diameter of the cross bar is 20-21mm, and the length is 1600-2000mm. A lead-in unit 2 is installed on the cross bar 104, and the lead-in 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, which are arranged along the circumference of the guide wheel 201. A base 101 is installed at one end of the vertical pole 103 away from the cross bar 104. The base 101 is a channel steel with a length of 1200-1300mm. A through hole is provided on the base 101, and a pipe fitting 102 is provided at the through hole. The pipe fitting 1 The diameter of 02 is 25-26mm, and the length is 150-250mm. The vertical rod 103 is installed in the pipe fitting 102. The two ends of the cross bar 104 are respectively provided with multi-way pipe fittings 105. The diameter of each port of the multi-way pipe fitting 105 can be selected according to the cross bar 104 or the vertical rod 103 to be connected. For example, the diameter of the connected cross bar 104 is 20mm, and the diameter of the vertical rod is 20.5mm. Therefore, the diameter of the multi-way pipe fitting 105 selected is The diameters are 20.1 mm and 20.6 mm to adapt to connecting the crossbar 104 with the vertical bar 103. The crossover unit 5 includes a bottom plate 501 for fixing the wire drum 3, a first rod 502 and a rotating member 503. One end of the first rod 502 is connected to the bottom plate 501, and the other end is connected to the rotating member 503. The rotating member 503 is provided with a second rod 504, and a crossover drum 505 is installed at one end of the second rod 504 away from the rotating member 503. The crossover drum 505 is rotatably connected to the second rod 504, and the crossover drum 505 swings or rotates around the axis of the second rod 504;

[0045] The assembly process of the wire-laying device includes: placing the base 101 on a flat and compacted ground, directly inserting the vertical pole 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, assembling the bracket 1 in this way, fixing the guide wheel 201 on the cross bar 104 through the strap 203, and the fixing position is determined according to the position of the wire drum 3 below, the rotating member 503 adopts a bearing with an inner diameter of 20-30mm, the diameter of the first rod is 20-50mm, the length is 200-500mm, and the size of the bottom plate 501 is selected according to the specifications of the wire drum. Select, weld the first rod 502 to the rotating member 503, and then weld the first rod 502 to the connecting base plate 501, connect the rotating member 503 to the second rod 504, and weld the crossover drum 505 to the end of the second rod 504 away from the rotating member 503. After the crossover unit 5 on the wire drum 3 is installed, pass the cable on the wire drum 3 through the crossover drum 505 and the guide wheel 201. When the wire-releasing personnel apply external force to pull, the cable drives the crossover drum 505 to rotate around the side of the wire drum 3 under the force state, and makes the crossover drum 505 swing or rotate around the axis of the second rod 504, so as to realize the wire-releasing function.

[0046] The above scheme has the following advantages. The bracket 1 makes the guide wheel 201 a certain distance away from the ground. During the wire pulling process, the ground and the cables on the wire drum 3 form a certain angle, so that the cables are not easily dragged on the ground during the wire unwinding process. The bottom plate 501 is connected to the wire drum 3. The cable first passes through the wire barrel 505 and then passes through the guide wheel 201 to unwind. It is suitable for wire drums 3 of different specifications. At the same time, the cables of multiple wire drums 3 are passed through the corresponding guide wheels 201, so that multiple wire drums 3 can be unwinded at the same time.
