Description

Technical Field

[0002] A mountain photovoltaic power station refers to a photovoltaic power station built under complex terrain conditions such as mountains and hills. The construction surface is uneven, with different orientations, and local areas are accompanied by mountain valleys. The available terrain area is irregular and scattered, with great design difficulty, high construction cost, and reduced power generation efficiency. In traditional flat terrains, large-scale planar layouts are often adopted for photovoltaic power stations. However, in mountain terrains, factors such as terrain undulation, slope, and wind direction need to be considered for more complex layout methods to make full use of mountain resources and improve the power generation efficiency of photovoltaic power generation.

[0003] In addition, during the construction operation of mountain photovoltaic projects, corresponding project construction equipment needs to be used, including wire laying tools for photovoltaic projects. During construction, wire laying is used to plan the installation positions of components and the routes of cables, and dotting is used to indicate the specific positions of component fixing positions, so as to ensure the safe and stable operation of photovoltaic components. However, for existing wire laying tools for mountain photovoltaic projects, during the corresponding wire laying operation, after the wire laying is completed, the wire harness often becomes loose after being retracted, which affects the quality of the next wire laying. Therefore, this technical solution needs to be improved.

[0004] Therefore, there is an urgent need to develop a wire laying tool for mountain photovoltaic projects that can prevent wire harness loosening. Summary of the Utility Model

[0025] Refer to Figure 1 , a wire laying tool for a mountain photovoltaic project, comprising a fixed seat 1, a clamping device 2 and a traction device 3 sequentially welded on the top of the fixed seat 1; the clamping device 2 includes a mounting table 21 and a compression device 22, the mounting table 21 is welded on the top of the fixed seat 1, the compression device 22 is an even number of groups, at least two groups, and the compression devices 22 are symmetrically arranged on the mounting table 21; between the symmetrically distributed compression devices 22 is the electric wire 4, and the compression device 22 gives the electric wire 4 a pressing force to ensure the smoothness of the electric wire 4 during the wire laying process.

[0026] Specifically as Figure 1 shown, the mounting table 21 is U-shaped, as Figure 2As shown in the figure, there are two sets of pressing devices 22. The two sets of pressing devices 22 are arranged one above the other inside the mounting table 21. The two sets of pressing devices 22 can slide inside the mounting table 21 to press the wire 4. Specifically, rectangular sliding grooves 211 arranged longitudinally are provided on both inner surfaces of the mounting table 21, as Figure 3 shown. The pressing device 22 includes two rectangular sliders 226 respectively cooperating with the rectangular sliding grooves 211 on both inner surfaces of the mounting table 21, a connecting rod 225 connecting the two sliders 226, and a clamping wheel 224 sleeved on the connecting rod 225. There is no relative rotation between the clamping wheel 224 and the connecting rod 225. A pressing spring 227 is fixed between the slider 226 and the sliding groove 211. The pressing spring 227 provides a downward pressure, and the slider 226 can slide up and down in the sliding groove 211. An auxiliary pressing mechanism is also provided on the pressing device 22. Specifically, fixing holes 212 are provided on both inner surfaces of the mounting table 21. The auxiliary pressing mechanism includes a fixing shaft 221 sleeved in the fixing hole 212, a guiding platform 222 integrally provided with the fixing shaft 221, a sliding rod 223 with one end sleeved on the guiding platform 222, and the other end of the sliding rod 223 is connected to the clamping wheel 224. A guiding column 2221 is provided at the bottom of the guiding platform 222. The inside of the guiding column 2221 is hollow, and the sliding rod 223 is sleeved inside the guiding column 2221. The sliding rod 223 can slide inside the guiding column 2221. A guiding spring 2222 is fixed between the sliding rod 223 and the guiding column 2221. The guiding spring 2222 provides a pressure on the pressing wheel along the direction of the guiding column 2221; the fixing shaft 221 is arranged on the side close to the pulling device 3, and the center line of the guiding column 2221 forms an acute angle with the horizontal line, so that the clamping wheel 224 can provide a greater and more stable pressure on the wire 4 during wire winding, to further improve the smoothness of the wire 4 during the wire routing process and facilitate the wire winding of the traction device.

[0027] Specifically, as Figure 4 shown, the pulling device 3 includes a U-shaped mounting seat 31 welded to the top of the fixed seat 1, a rotating shaft 32 sleeved on the mounting seat 31, a wire winding disc 34 sleeved on the rotating shaft 32, a turntable 33 provided at one end of the rotating shaft 32, a clamping seat 35 provided between the turntable 33 and the rotating shaft 32, and a connecting block 36 provided on the top of the mounting seat 31.

[0029] As Figure 1 shown in the figure, in order for the workers to clearly observe the state of the wire harness and prevent the wire 4 from detaching from the clamping wheel 224, through windows 213 are provided on both sides of the installation table 21.

[0030] Working process: When winding the wire, one end of the wire 44 is passed through between the two clamping wheels 224, and through the guide wheel 23, the wire 44 is wound around the winding disc 34. At this time, the fixing pin 38 is pulled up, and after the fixing pin 38 is disengaged from the clamping seat 35, the turntable 33 is rotated. At this time, the wire 44 remains smooth under the pressure of the clamping wheel 224 and can be wound quickly, and the phenomenon of loose winding of the wire harness can be reduced. When the winding is approaching the end, ensure that the other end of the wire 44 is still between the two clamping wheels 224. At this time, the fixing pin 38 is inserted so that the fixing pin 38 is sleeved with the clamping seat 35, and the wire winding is ended. When wire releasing is required, the fixing pin 38 is pulled up, and after the fixing pin 38 is disengaged from the clamping seat 35, the wire 44 can be pulled to release the wire.
