Description

Technical Field

[0001] This invention relates to a method for laying power collection lines on the same tower, belonging to the field of photovoltaic construction technology. Background Technology

[0002] During the construction of a photovoltaic power station, it is necessary to build a collection line to gather and transmit the AC power generated by the inverters of each photovoltaic power generation unit to the substation. When the collection line passes through the tower, the power transmission line coiled on the reel needs to be laid out.

[0003] In existing power transmission line laying construction (see Chinese Patent Publication No. CN216904243U), although the cable reel can be wound up and unwound by the rotation provided by the drive motor on the tower, the tower is a whole and is equipped with drive motors and other equipment. The equipment is too much and it is inconvenient to move and adjust the tower. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a method for laying out power collection lines on the same tower.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for laying current collectors on the same tower, comprising: the shafts at both ends of the cable reel are rotatably mounted on a support frame; by swinging the rotating arm, the friction speed control body is controlled to contact and rub against the wooden disc at the end face of the cable reel, thereby controlling the rotation of the cable reel to release the speed of the current collector, so as to meet the requirements for laying and installing current collectors on the tower.

[0007] The number of support frames is two, and they are spaced apart on the construction ground.

[0008] The shafts at both ends of the cable reel are rotatably mounted to two support frames.

[0009] The support frame includes a base for placement on the construction ground, the base is fixed to a rotating support seat by opposing inclined legs, and the rotating support seat is equipped with a rotating support component for rotatably mounting the shafts at both ends of the cable reel.

[0010] The rotating support is a rotating sleeve or bearing that provides rotation.

[0011] The cable reels are located relatively far from the towers, and the collector wires on the cable reels are laid and installed on the towers.

[0012] It also includes protective mats placed on the construction site, with the protective mats contacting the middle of the drooping conductor.

[0013] A rotating arm is rotatably hinged to the support frame. The bottom end of the rotating arm is rotatably hinged to one support frame, and the top end of the rotating arm extends to another support frame. The rotating arm has a notched arm section, and baffles are fixed to the sides of both ends of the notched arm section. A groove space is formed between the baffles to press and clamp a friction speed control body. The friction speed control body contacts and rubs against the radial outer periphery of the wooden disc on the end face of the cable reel.

[0014] The friction control and speed control body is made of wood.

[0015] The beneficial effects of this invention are as follows: when the cable reel's cable laying position needs to be adjusted, the two support frames can be moved individually, and then the shafts at both ends of the cable reel and the rotating support components on the two support frames can be rotatably installed, thereby enabling the laying of the cable collector wires on the cable reel. This solves the problem that the tower is a whole and the equipment is installed there, making it inconvenient to move and adjust the tower. Attached Figure Description

Detailed Implementation

[0017] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0018] like Figures 1 to 3 As shown.

[0019] This application discloses a current collector line co-layout structure, comprising: There are two support frames 2 spaced apart on the construction ground 1. Each support frame 2 includes a base 21 for placing on the construction ground 1. The base 21 is fixed to a rotating support seat 23 by opposing inclined legs 22. The rotating support seat 23 is equipped with a rotating support member 24 for the rotatable installation of the shafts 31 at both ends of the cable reel 3. The rotating support member 24 is a rotating sleeve or bearing that can provide rotation.

[0020] When the cable reel 3 needs to be adjusted in position, the two support frames 2 are moved individually. Then, the shafts 31 at both ends of the cable reel 3 and the rotating support members 24 on the two support frames 2 can be rotatably installed to realize the laying of the collector wires 32 on the cable reel 3. This solves the problem that the tower is a whole and the equipment is installed, so it is inconvenient to move and adjust the tower.

[0021] It also includes the iron tower 4, which is far away from the cable reel 3, and the collector wire 32 on the cable reel 3 is laid and installed on the iron tower 4.

[0022] It also includes a protective mat 5 placed on the construction surface 1. The protective mat 5 contacts the middle of the drooping conductor 32 to prevent the middle of the drooping conductor 32 from directly contacting the construction surface 1 and causing wear. The middle of the conductor 32 will droop during the overlay of the cable reel 3.

[0023] A rotating arm 6 is rotatably hinged to the support frame 2. The bottom end of the rotating arm 6 is rotatably hinged to one support frame 2, and the top end of the rotating arm 6 extends towards another support frame 2. The rotating arm 6 has a notched arm section 61, and baffles 62 are fixed to the sides of both ends of the notched arm section 61. A groove is formed between the baffles 62 to allow a friction speed control body 63 to be tightly fitted. The friction speed control body 63 contacts and rubs radially with the wooden disc 33 on the end face of the cable reel 3. The friction speed control body 63 is made of wood, and its contact and friction with the wooden disc 33 on the end face of the cable reel 3 controls the rotational speed of the cable reel 3. The friction speed control body 63 is replaced when it wears out.

[0024] The present application discloses a method for laying power collection lines on the same tower, comprising: the shafts 31 at both ends of the cable reel 3 are rotatably mounted on the support frame 2; by swinging the rotating arm 6, the friction speed control body 63 is controlled to contact and rub against the wooden disc 33 on the end face of the cable reel 3, thereby controlling the rotation of the cable reel 3 to release the speed of the power collection line 32, so as to meet the requirements for laying and installing the power collection line 32 on the tower 4.
