Description

Technical Field

[0001] This utility model relates to a weeding machine for photovoltaic stations at oilfield well sites, belonging to the technical field of well site auxiliary equipment. Background Technology

[0002] Currently, the oilfield industry is vigorously developing photovoltaic green energy, utilizing areas such as oil and water well sites and storage facilities to build distributed photovoltaic power stations. Many oilfields have a large number of oil and water wells. Oil and water well sites are mainly divided into several categories, including pumping unit sites, wellhead sites, tubing sites, and equipment parking sites. Tubing sites are mainly used to place tubing and sucker rods during downhole operations and are usually idle. Equipment parking sites vary from well site to well site and are generally used for pumping unit installation and maintenance, as well as parking large vehicles during downhole operations. Some areas are also idle for extended periods.

[0003] Although the individual idle sites at each well site are small, the cumulative area is substantial. By fully utilizing these numerous scattered idle sites to install distributed photovoltaic (PV) systems and generate electricity from sunlight, the value of idle land and well sites is maximized, while also helping the oilfield reduce costs and increase efficiency, contributing to "low-carbon" development. Distributed PV stations at oilfield well sites have the following characteristics: 1. Each site is small, and the ground is equipped with numerous counterweight concrete blocks and other components, making it difficult for large machinery to enter; 2. When downhole operations are required, the PV panel supports need to be deformed to make room; 3. The PV panels need to face the sun while operating, and their lower ends are close to the ground, creating many low and narrow spaces that are difficult for equipment and personnel to access.

[0004] To maximize the efficiency of solar power generation, routine maintenance of solar photovoltaic (PV) panels is crucial. Many factors influence the efficiency of solar PV panels, with solar irradiance being one of the most significant. Maintaining and improving the power generation efficiency of installed PV panels hinges on cleaning and weed control. Currently, there are various methods for regularly dusting and weeding PV panels, including water washing, mulching, surface stabilization, chemical weeding, and manual / mechanical weeding. Among these methods, mulching and surface stabilization are relatively expensive, while chemical weeding can impact the surrounding environment and crop growth.

[0005] Patent document with publication number CN 222583026U discloses a multifunctional forestry weeding device that uses a combination of manual and mechanical methods for weeding. It requires workers to hold the lawnmower by hand or carry it on their backs and rely on their arms or bodies to rotate the blades to cut grass, resulting in high labor intensity. Moreover, the distance between the rotating blades of the lawnmower is not long enough to completely cover the narrow area under the photovoltaic panel, resulting in incomplete weeding and other defects.

[0050] The output shaft of the gasoline engine 9 drives the internal hexagonal sleeve 11 to rotate through the coupling 10. The internal hexagonal sleeve 11 drives the hexagonal rod 12 to rotate. The hexagonal rod 12 drives the blade drive shaft 14 to rotate through the universal joint 13, which in turn drives the weeding blade 15 or the weeding steel rope to rotate at high speed, thereby achieving grass cutting.

[0051] The circular cover plate 21 has a concave-facing arc-shaped grass barrier 22 on its rear side. The upper end of the arc-shaped grass barrier 22 is fixed to the lower part of the telescopic inner rod 19 to prevent grass clippings from flying towards the workers.

[0052] The left and right sides of the rear support block 6 extend downward to the bottom of the keel 1. The outer walls of the left and right sides of the rear support block 6 are respectively welded with support block outer ears 23. The top of the two crossbeams 3 near the outer ends of the wheels 4 are respectively welded with crossbeam upper ears 25. Shock absorbers 24 are respectively hinged to the two support block outer ears 23. The lower ends of the two shock absorbers 24 are respectively hinged to the support block outer ears 23, thereby realizing independent suspension and shock absorption of the two wheels 4.

[0053] The upper rear end of the keel 1 bends upward and connects to the lower end of the handle telescopic tube 26. The upper telescopic tube 28 of the handle is inserted into the upper port of the handle telescopic tube 26, and a height adjustment lock sleeve 27 is installed on the outer periphery of the insertion point. The height of the handrail is adjusted in advance according to the operator's body height. After the insertion depth of the upper telescopic tube 28 in the handle telescopic tube 26 is adjusted to be appropriate, the height adjustment lock sleeve 27 is rotated to lock the upper telescopic tube 28 of the handle.

[0054] A handrail connecting seat 29 is fixed to the top of the telescopic tube 28 on the handle. The middle part of the handrail tube 30 is embedded in the horizontal groove at the top of the handrail connecting seat 29, and is secured by a cap and screws. The left and right ends of the handrail tube 30 bend upwards and then backwards to form a handrail for workers to hold on to. Disc brakes 5 are provided on the inner sides of the two wheels 4, and brake levers 30 are provided below the handrails on both sides. The base of the brake levers 30 is connected to the disc brakes 5 through brake lines 32. The brake levers 30 can brake one side of the wheel 4, making it easy to turn to that side. The front cutter head also turns to that side, thus achieving flexible left and right swinging.

[0055] The right handlebar is also equipped with a throttle, which can be used to adjust the speed of the gasoline engine 9 to change the speed of the weeding blade 15.
