[0018] Compared with the prior art, the present invention has the following advantages and technical effects:

[0019] 1.

[0020] 2. The weeds are transported to the trapping device using their own gravity. The power generated is then recovered into the stepper motor's battery, which drives the pressure roller. The pressure roller squeezes the hose, causing the refrigerant inside to dissipate heat in the condenser, heating and drying the weed pile. The heat is then absorbed by the evaporator from the photovoltaic panel backplane, cooling the panel and improving panel efficiency. A conveyor system then delivers the cut weeds to a designated area, where they can reach high temperatures under solar radiation or through slow oxidation and heat generation from the weed pile. Heat transferred from the photovoltaic panel backplane to the weed pile, in line with the habits of red imported fire ants, attracts them to the weed pile, allowing for further control. This prevents red imported fire ants from gnawing on power lines without the need for external input, reducing the cost of red imported fire ant control in power plants and improving economic efficiency.

[0021] 3. Using the weeds cut by the wire to prevent and control red imported fire ants instead of using chemical additives is beneficial to improving environmental benefits and practicing the concept of environmental protection. The cut weeds are reused, reducing the secondary cost of weed treatment and improving the economic benefits of the power station. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] It should be noted that, unless there is a conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

All other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0027] like Figures 1 to 2 As shown, the present invention provides an integrated system for weed removal and fire ant control in a photovoltaic power station, comprising:

[0028] A wire cutting device is installed below the photovoltaic panel and is used to cut the weeds 1 below the photovoltaic panel. The wire cutting device is equipped with a laser sensor 7 for real-time detection of the growth status of the weeds 1 and a spraying assembly.

[0029] The conveying device is provided with a collecting tank at the bottom of the wire cutting device, and one end of the conveying device is connected to the collecting tank; the conveying device is arranged at an angle, and a power recovery component is provided on the conveying device;

[0030] The trapping device is arranged at the other end of the conveying device, and the elevation of the trapping device is lower than the elevation of the collecting tank; the trapping device is equipped with a spray assembly;

[0031] The heat dissipation device has an evaporation end mounted on the back panel of the photovoltaic panel, a condensation end of the heat dissipation device is arranged corresponding to the trapping device, and a power recovery component is used to drive the flow of refrigerant in the heat dissipation device.

[0032] A further optimized solution is provided. To facilitate cutting of weeds 1, the wire cutting device includes a motor 2, and a long wire 3 is connected to the output shaft of the motor 2; a laser sensor 7 is installed on the top of the motor 2, and a plurality of spray ports 11 are provided on the body of the motor 2, and the plurality of spray ports 11 are arranged along the circumference of the motor 2.

[0033] To further optimize the solution, the conveying device includes a conveyor belt 8 connected to the collection trough, the conveyor belt 8 is set at an angle, and a weight sensor 10 is installed on the conveyor belt 8; the power recovery component is coordinated with the conveyor belt 8 in transmission.

[0034] According to a further optimized solution, a one-way partition 9 is installed on the conveyor belt 8 to prevent the weeds 1 from being transported in the reverse direction.

[0035] According to a further optimization scheme, the power recovery component includes a stepper motor 12, and a pressure roller 13 is connected to the output shaft of the stepper motor 12. The end of the pressure roller 13 is driven by a peristaltic pump in the heat dissipation device.

[0036] According to a further optimized solution, the trapping device includes a weed pile 5. To facilitate packing of the weed pile 5, a drawstring mesh barrier cover 6 is provided on the outer side of the weed pile 5.

[0037] To further optimize the solution, in order to reduce the possibility of escape of red fire ants, the drawstring mesh barrier cover 6 is provided with a coating to prevent red fire ants from biting, and the coating can be made of delphinium essential oil.

[0038] To further optimize the solution, the spray assembly includes a fixing frame 19, on which a semicircular cover 16 is installed, and the semicircular cover 16 is arranged above the weed pile 5; an iron guardrail 17 is installed on the outer wall of the semicircular cover 16, and the iron guardrail 17 is arranged along the circumference of the semicircular cover 16, and a plurality of spray ports 18 are provided on the iron guardrail 17, and the spray ports 18 are used to spray water vapor, and the plurality of spray ports 18 are arranged at equal intervals along the circumference of the iron guardrail 17.

[0039] The dispersed arrangement of the spray ports 18 makes the wind speed of the sprayed water vapor not high, so it will not scare away the red fire ants. It also creates a high temperature environment, causing the red fire ants to gather towards the trapping device, thereby preventing and controlling them.

[0040] To further optimize the solution, the heat dissipation device includes an evaporator 15 and a condenser 4. The evaporator 15 is installed on the back plate of the photovoltaic panel. A water heating device is correspondingly provided at the condenser 4. The water vapor outlet of the water heating device is connected to the spray port 18; a loop is formed between the evaporator 15 and the condenser 4 through a hose 14. A peristaltic pump is provided on the hose 14, and the power recovery component is coordinated with the peristaltic pump transmission; the outlet end of the condenser 4 is connected to a hot water fluorine heat exchanger, and the outlet end of the hot water fluorine heat exchanger is connected to the evaporator 15.

[0041] The integrated weed removal and fire ant control system for a photovoltaic power station provided by this invention operates as follows: a wire cutting device is installed beneath the photovoltaic panels, and a laser sensor 7 is mounted on the wire cutting device. This device monitors the growth status of weeds 1 in real time and automatically activates the wire cutting device at a specific time, achieving automated weed removal and reducing the cost of manual weed removal. The wire cutting device consists of a motor 2 and a long wire 3. When not in operation, the wire 3 is stagnant. When the motor 2 is activated, the wire 3 rotates at high speed, generating a shear force sufficient to cut the weeds 1. The power used by the wire cutting device's motor 2 is generated by photovoltaic power generation. Excessive photovoltaic power is stored in a battery. When the battery capacity is exceeded, the heat is converted into heat and transmitted to a boiler to burn the weeds 1.

[0042] A collection tank is provided under the wire cutting device, which is connected to a conveying device. A weight sensor 10 is provided on the conveying device. By setting a certain weight value, the conveying device is automatically turned on to convey the weeds 1 when the set weight is reached, so that the weeds 1 are conveyed to a designated trapping device, thereby achieving organic combination and integration of the equipment. A stepper motor 12 and a pressure roller 13 are installed on the conveying device to recycle the power generated by the weeds 1 moving on the conveying device due to their own gravity. This power is recovered into the battery capacitor of the stepper motor 12, and the stepper motor 12 is used to drive a peristaltic pump to convey refrigerant to the photovoltaic panel to cool the temperature on the back of the photovoltaic panel, thereby improving the efficiency of the photovoltaic panel.

[0043] By adding a spray port 11 to the wire cutting device, a drug that inhibits the growth of weeds 1 can be sprayed when the weeds 1 grow too rapidly and exceed the required amount. When the boiler needs a large amount of weeds 1 to burn or the number of red imported fire ants is too large, resulting in a shortage of weeds 1, a growth agent can be sprayed to promote their growth. By setting up a laser sensor 7, the growth status of the weeds 1 is monitored and the weeds 1 are treated in time to prevent them from eroding and damaging the photovoltaic panels. The red imported fire ants are gathered together to build nests through a trapping device and are caught in one swoop to prevent them from gnawing and damaging the power station wires. The mesh barrier is coated with delphinium essential oil to prevent the red imported fire ants from biting, thereby reducing the possibility of the red imported fire ants escaping.

[0044] The refrigerant is transported to the evaporator 15 on the back of the photovoltaic panel through the hose 14. The refrigerant exchanges heat with the outside air through the evaporator 15, vaporizes and absorbs heat, thereby achieving a cooling effect, reducing the temperature on the back of the photovoltaic panel and absorbing heat. The vaporized refrigerant flows back to the condenser 4, and uses the absorbed heat to heat water, turning the water into water vapor and spraying it toward the weed pile 5 through the spray port 18, preheating and drying the weed pile 5, reducing its internal water content while increasing its own temperature, which is beneficial for it to burn normally for heat supply after being sent to the boiler, and also beneficial for it to attract red imported fire ants that like high temperatures.

[0045] A semicircular hood 16 is installed on the trapping device. Iron guardrails 17 are installed along the semicircular hood 16, and spray nozzles 18 are provided. Spray nozzles 18 are dispersed to minimize the velocity of the water vapor spray, thereby preventing the ants from fleeing. The nozzles also create a high-temperature environment, attracting the ants to the trapping device, thereby preventing and controlling the ants. The semicircular hood 16 also secures the drawstring mesh barrier 6 used in the trapping unit.

[0046] By wrapping a drawstring mesh barrier 6 around the weed pile 5, after a period of time, when the number of red imported fire ants reaches a certain level or threatens to become a threat, the weed pile 5 can be bundled by pulling the cord and fed into the boiler to burn the weeds 1, thereby reusing the weeds 1 and increasing the boiler's fuel source. Since the boiler's fuel source is the weeds 1, the source is unstable and affected by various factors, such as the growth habits of the weeds 1 and weather and climate, the boiler's heating supply is also unstable. Therefore, the boiler's heating supply is mainly used to provide domestic hot water. On the one hand, the weeds 1 are easy to burn, requiring little energy to restart. On the other hand, when there are few weeds 1 and the demand for hot water is not strong, the boiler can operate at a low load. During this period, the heat from the burning weeds 1 is mainly used to maintain the boiler temperature, without supplying hot water.

[0047] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
