Description

Technical Field

[0001] This utility model relates to the field of photovoltaic engineering technology, and in particular to an automatic weed-removing device for photovoltaic power stations. Background Technology

[0002] With the continuous expansion of photovoltaic power plant construction and the development of intelligent systems, higher demands are being placed on the efficiency and automation of power plant operation and maintenance. As a crucial aspect of photovoltaic power plant maintenance, operators expect highly efficient, environmentally friendly, and intelligent weed control systems capable of precise weed removal and unmanned management, thereby reducing manpower input and improving the overall operational efficiency of the power plant.

[0003] Weed growth can obstruct the surface of solar panels, reducing the efficiency of solar energy reception and conversion, and lowering the power generation capacity of the power station. In addition, the spread of weeds can alter the surrounding environment of the equipment. In severe weather, water accumulation and wind-borne debris in weedy areas can damage the equipment. Dry weeds in winter can also easily cause fires, posing a safety hazard. Overgrown weeds can attract snakes, insects, rodents, and ants, threatening the safety of inspection personnel. Current technology involves manual weeding, with personnel using sickles, hoes, and shovels to directly cut or remove the roots of weeds. However, manual weeding is inefficient. For photovoltaic power stations that cover thousands of acres, the labor cost is high and the efficiency is low. Moreover, working in the high temperatures of summer poses a risk of heatstroke. Due to the dense cables and supports within the power station, careless operation can lead to electric shock or tripping. Utility Model Content

[0021] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The limiting component 304 includes a limiting post 3042, the outer wall of the limiting post 3042 is slidably connected to the inner wall of the rotating shaft 2062, the outer wall of the rotating shaft 2062 is provided with a plurality of limiting holes 3041, the outer wall of the limiting post 3042 is threadedly connected to a limiting ring 3044, the right end of the limiting post 3042 is fixedly connected to a fixing block 3043, the front side of the mounting plate 1 is fixedly connected to an anti-collision block 4, and the outer wall of the limiting post 3042 is slidably connected to the inner wall of the limiting hole 3041.

The anti-collision block 4 can absorb part of the impact force and protect the limiting component 304 from damage.

[0022] Working principle: When the motor 2061 is started, the motor 2061 drives the rotating shaft 2062 to rotate. The rotating shaft 2062 then drives the fan 2063 to rotate. During the rotation, the fan 2063 sucks the cut weeds upward. The sucked-in weeds flow along the outer walls of the triangular plate 2051 into the collection box 2031. The remaining weeds slide along the outer walls of the inclined plate 2052 into the collection box 2031. When the collection box 2031 is full of weeds, the handle 2032 can be pulled out to process the weeds inside. This achieves the collection and processing of weeds, preventing the cut weeds from still piling up on the ground and causing environmental pollution. When the cutting height needs to be adjusted, rotate the limiting ring 3044, and the limiting post 3042 will lose its limit. The limiting post 3042 can then be pulled out from the inside of the limiting hole 3041. Then, pull the rotating shaft 301 to adjust to the appropriate height, and then insert the limiting post 3042. Twist the limiting ring 3044 to fix the rotating shaft 301 in that position. When the rotating shaft 301 rotates, the cutting fan 303 can cut the weeds, and the cutting blade 302 can further cut and crush the weeds, making it easier for the weeds to be sucked into the collection box 2031. This realizes the adjustment of the cutting height, allowing the staff to adjust the cutting depth according to the needs, thereby improving the practicality of the equipment.
