Description

Technical Field

[0002] Some photovoltaic power stations are built in mountainous areas with high altitudes. The project area is located on the top of the mountain and the arrays are concentrated together. For example, a photovoltaic project in a county in Yunnan has an altitude of 1700m to 2160m. The structural stability of the project area is poor, the terrain slope ranges from 15 to 39°, and more than 70% of the entire photovoltaic field has a slope of 30 to 39°. The 3#~5# array reaches more than 50, and the mountain slope of the array in this area is about 500m long. The photovoltaic panels are arranged facing north and south (30° east by north). Because the slope is steep, the entire photovoltaic field is limited by the site scope and slope, and it is impossible to build roads on the site, and the equipment cannot be transported to each photovoltaic array. For such construction areas, only a combination of manual transportation and drone lifting can be used, but the two solutions are inefficient and costly, and cannot efficiently meet the construction progress requirements; therefore, it is necessary to design a simple transportation device for photovoltaic components on steep slopes in mountains to solve the above problems. Summary of the invention

The utility model has the characteristics of low cost, easy installation, simple operation, and efficient solution to the problem of transporting long-length photovoltaic components on steep slopes in mountains.

[0004] In order to realize the above technical features, the technical solution adopted by the utility model is:

[0006] Furthermore, the traction device is preferably a winch, which is fixed by using nearby buildings or ground, and the tail is blocked and fixed with a wire rope to avoid overturning. When the traction force is large, it is necessary to set up a support in front of the winch to prevent the winch from being tilted due to single-sided force.

[0007] Furthermore, a guide wheel is fixed on the slope top surface in front of the winch for guiding the steel cable.

[0008] Preferably, the transport trolley comprises a rectangular frame structure formed by connecting a main beam and a secondary beam, and a plurality of connecting beams are connected to the inner wall of the frame.

[0009] Preferably, a plurality of stop bars are vertically connected to the upper surface of the frame structure for limiting the position of goods.

[0011] Preferably, the trolley track includes a plurality of anchoring mechanisms, which include columns symmetrically arranged on both sides, the bottom ends of the columns are plug-fitted into the slope, and the top ends of the columns are vertically connected to the two ends of the track crossbar through steel pipe fasteners.

[0012] Furthermore, in addition to the columns, diagonal braces are also provided for fixing to the slope to enhance the stability of the structure.

[0013] Preferably, a sleeve is sleeved on the outer surface of the rail crosspiece and connected to the lower surface of the rail, and the rail is connected to the upper surfaces of the sleeves of multiple anchoring mechanisms, so that the multiple anchoring mechanisms are connected into a whole.

[0014] Furthermore, a collision head structure is provided at both ends of the track to prevent the transport trolley from running off the track due to excessive recovery or falling, thereby improving safety.

[0015] Preferably, the track includes two left and right tracks, the spacing between the tracks is the same as the spacing between the running mechanisms of the transport trolley, and the two tracks are connected and reinforced by a connector.

[0016] Preferably, the operating mechanism comprises a raised slider, which slides into a slot provided on the side surface of the track.

[0017] Furthermore, the hanging points at both ends are symmetrically designed and are hung with the hanging points at both ends of the pressure steel pipe when in use.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model adopts a simple transportation device to efficiently transport photovoltaic panels to the construction area in the case that the photovoltaic slope is steep and long and it is impossible to use transportation equipment to transport the photovoltaic string components to the construction area, reducing the input of manual handling and drone lifting to meet the construction needs. The device has a simple structure, is easy to make, install, transport and maintain, and only needs to adjust the length of the winch wire rope according to the length of the mountain slope on site to meet the transportation task of the photovoltaic string components;

[0020] 2. The transport trolley of this device is suitable for the situation where the hillside is ups and downs and there are local broken lines. By changing the wheelbase, the transportation stability can be ensured to meet the transportation requirements;

[0043] Embodiment 2:

[0044] The traction mechanism of this device uses a 2T winch (20 meters / minute, motor power: 7.5kw) and is installed in a place with a wide field of vision for easy observation by operators and commanders. The center line of the guide pulley is perpendicular to the center line of the drum and is separated from the drum by a certain distance (L) greater than 20 times the width d of the drum to ensure that the deflection angle of the wire rope does not exceed 0.01 when it is wound around the two sides of the drum. In this way, the steel wires can be arranged in order on the drum without being wound obliquely or overlapping each other. The drum is customized to increase the drum's rope capacity (500m). The winch adopts , Multi-strand steel wire rope is used as a traction rope, which can meet the traction of 12 photovoltaic panels (400kg), with a safety factor of more than 9 times.

[0045] Transport trolley 2 adopts Galvanized square tube ( ) is mainly made of load-bearing frame, photovoltaic panel baffle ( Angle steel) and operating mechanism 4 (load-bearing rubber wheel 100kg or flangeless steel wheel).

[0046] Trolley track 3 is mainly supported by 8# channel steel. Track 9, Steel pipes are welded to serve as rail 9 connectors 91 (one connector 91 is 4m apart), and inner diameters are welded every 4m below the double rails 9. The sleeve 81 is mainly used to quickly fix the rail 9 crosspiece 8. The steel pipe passes through the casing 81 and bears the cross-arm load of the track 9; the column 6 still adopts The steel pipe is connected to the cross arm with fasteners, and the diagonal brace is connected to the column 6 with fasteners.

[0047] The working principle of the utility model is as follows:

[0048] The winch should be fixed to nearby buildings or ground as much as possible, and the tail should be locked and fixed with a wire rope. After fixing, the winch should not slide or overturn. When the traction force is large, a support should be set up in front of the winch to prevent the winch from being deflected due to single-sided force.

[0049] The guide wheel 10 can be placed on a cast foundation or a steel structure foundation using a fixed pulley. A pit (with a depth of not less than 500 mm) must be dug to pre-embed the foundation to ensure the stability of the guide wheel 10.

[0050] The double track 9 is made of 8# channel steel, connected with steel pipes every 4m, and the inner diameter casing 81 is welded below (the casing 81 is provided with auxiliary angle steel on the slope surface to increase the welding surface).

[0053] A collision head must be installed at both ends of track 9. At the same time, the winch operator and the upper and lower command personnel communicate using walkie-talkies to avoid accidents caused by trolley derailment.

[0054] Before operation, the electrical and brake of the winch, the wire rope, and the stability of the full-stroke track 9 are checked. If the inspection is normal, the full-stroke transport trolley 2 no-load operation test can be carried out.

[0055] The simple transport device is tested and checked normally without load. The transport trolley 2 can be driven into the upper part of the track 9, and the photovoltaic panels are manually transported to the trolley (the contact surface is protected by a soft cushion). After the transportation is completed, the photovoltaic panels are fixed to the trolley with a drawstring.

[0056] The winch is started, the brake is opened, and the winch pulls the transport trolley 2 at a constant speed of 20m / min along the track 9 to slide down to the required transportation position, and the photovoltaic panels are manually unloaded and transported to the installation position along the mountain contour line.

[0057] After the unloading of the traction transport trolley 2 is completed, the transport trolley 2 is manually towed to the top of the mountain using a traction rope, and the photovoltaic components are loaded again to repeat the above operation process.
