[0002] In order to further improve the quality and safety of power supply and beautify the urban environment, in recent years, it has been proposed to bury urban overhead lines underground, transform the original power grid, and use cable trenches for laying cables in cities. This requires the use of line racks to lay the wires.

[0003] At present, the height of the line racks used in existing power stations is usually fixed, which means that after the workers have completed the installation of the cables, the height of the cables from the ground cannot be adjusted. This has certain restrictions on the terrain of some towns and cities, resulting in low practicality of the power station pay-out racks. Utility Model Content

A support plate 140 is installed on the upper end of the lifting seat 130, and a wire pay-off frame 150 is installed on the surface of the support plate 140. In a specific implementation, the base 100 can support the support seat 110, and the support seat 110 can support the rotating member 220. By starting the motor 210, it drives the lifting seat 130 to move along the inner wall of the placement groove 120, and then drives the support plate 140 and the wire pay-off frame 150 to move up and down. The wire pay-off frame 150 can support the cable, which is beneficial to the stability of the cable on the power station line frame.

[0027] In this embodiment, the surface of the base 100 is threadedly connected with bolts 170, and at least two bolts 170 are provided. In a specific implementation, the base 100 can be installed on the ground by using multiple bolts 170, which is beneficial to the stability of the device on the ground; the surface of the lifting seat 130 is connected with a limiting ring 131, and the surface of the limiting ring 131 is connected with a wear-resistant pad 132, and the wear-resistant pad 132 is in contact with the inner wall of the placement groove 120. In a specific implementation, the lifting seat 130 can be moved upward by the cooperation of the limiting ring 131 and the placement groove 120, and the lifting seat 130 can be moved upward by a fixed distance from the inner wall of the placement groove 120. The possibility of falling off can be reduced by the wear-resistant pad 132, which can reduce the contact between the limit ring 131 and the inner wall of the placement groove 120, and the possibility of wear. It should be noted that the wear-resistant pad 132 can be made of rubber or silicone. There are several pay-off racks 150, and the surface of the pay-off rack 150 is provided with a protective pad 151.

The protective pad 151 can reduce the contact between the cable and the pay-off rack 150, and the possibility of wear can be reduced. It should be noted that the protective pad 151 can be made of rubber or silicone.

[0028] See also Figure 1-Figure 4 The height adjustment device 200 includes a motor 210 and a rotating member 220. The motor 210 is mounted on the surface of the base 100, and the output shaft of the motor 210 is meshed with the rotating member 220. The rotating member 220 is rotatably mounted in the support seat 110, and one end of the rotating member 220 is connected to a screw rod 230. The lifting seat 130 is threadedly sleeved on the surface of the screw rod 230. A convex block 240 is mounted on the surface of the base 100, and a guide rod 160 is mounted on the surface of the support plate 140. The guide rod 160 is slidably inserted in the convex block 240. In the specific implementation, by starting the motor 210, its output shaft drives the support seat The rotating member 220 in 110 rotates, thereby driving the screw rod 230 to rotate, so that the lifting seat 130 and the support plate 140 move upward along the inner wall of the placement groove 120, which is beneficial to adjusting the height of the wire rack 150 and the cable, and reducing the possibility that the height of the cable from the ground cannot be adjusted after the cable is installed. Because the guide rod 160 is slidably inserted in the protrusion 240, when the screw rod 230 drives the lifting seat 130 to move, the guide rod 160 on the surface of the support plate 140 can move along the inside of the protrusion 240, which is beneficial to improve the stability of the lifting seat 130 and the support plate 140 during the up and down movement.

[0029] In this embodiment, a support block 180 is installed on the surface of the base 100, and the motor 210 is installed on the surface of the support block 180. In the specific implementation, the motor 210 is installed on the surface of the support block 180, which is beneficial to the stability of the motor 210 on the base 100 and the device; the output shaft of the motor 210 is connected to the first bevel gear 211, and the first bevel gear 211 is meshed with the rotating member 220. In the specific implementation, by starting the motor 210, its output shaft drives the first bevel gear 211 to rotate, and the first bevel gear 211 will drive the rotating member 220 to rotate, and then the screw rod 230 drives the lifting seat 130 to move up and down, so as to facilitate the adjustment of the height of the cable from the ground.

[0030] A cavity 111 is provided in the support seat 110, and the first bevel gear 211 and the rotating member 220 are both located in the cavity 111. In a specific implementation, the first bevel gear 211 and the rotating member 220 are arranged in the cavity 111 to reduce the possibility of the first bevel gear 211 and the rotating member 220 being damaged by external influences; the rotating member 220 includes a connecting rod 221 and a second bevel gear 222, the connecting rod 221 is rotatably installed in the cavity 111, and the connecting rod 221 is respectively connected to the second bevel gear 222 and the screw rod 230, and the second bevel gear 222 is meshedly connected with the first bevel gear 211. In a specific implementation, the second bevel gear 222 is driven to rotate by the first bevel gear 211, and the second bevel gear 222 can drive the connecting rod 221 and the screw rod 230 to rotate, thereby driving the lifting seat 130 to move up and down, so as to facilitate the adjustment of the height of the pay-off frame 150 and the cable from the ground.

[0031] Specifically, the working principle of the power station line rack is as follows: when in use, the base 100 is installed on the ground by bolts 170, which is conducive to the stability of the power station line rack on the ground, and the cable is placed on the protective pad 151 on the surface of the pay-off rack 150 to facilitate the support of the cable.
