[0001] The present invention relates to the technical field of photovoltaic power stations, and in particular to an integrated system for weed removal and red fire ant control in a photovoltaic power station. Background Art

[0002] Photovoltaic power stations are one of the most promising renewable energy generation technologies. Photovoltaic power stations are mainly composed of photovoltaic panels, controllers and inverters.

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

[0028] A wire cutting device is installed under the photovoltaic panel, and is used to cut the weeds 1 sent from the photovoltaic panel; a laser sensor 7 for real-time detection of the growth status of the weeds 1 is installed on the wire cutting device, and a spraying component is provided on the wire cutting 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] According to a further optimized solution, the conveying device includes a conveyor belt 8 connected to the collecting trough, the conveyor belt 8 is inclined, and a weight sensor 10 is installed on the conveyor belt 8; the power recovery component cooperates 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 matched with the 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] A further optimized solution is that 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 arranged 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 spray ports 18 are dispersedly arranged so that the wind speed of the sprayed water vapor is not high, so the red fire ants will not be scared away. A high temperature environment is also created, so that the red fire ants gather towards the trapping device, thereby preventing and controlling them.

[0040] A further optimized solution is that 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 a power recovery component cooperates with the peristaltic pump transmission. The outlet end of the condenser 4 is connected to a water-discharging fluorine heat exchanger, and the outlet end of the water-discharging fluorine heat exchanger is connected to the evaporator 15.

[0041] The integrated system for weed removal and red fire ant control in a photovoltaic power station provided by the present invention has a working principle as follows: by installing a wire cutting device under a photovoltaic panel, installing a laser sensor 7 on the wire cutting device, detecting the growth state of weeds 1 in real time, and automatically starting the wire cutting device at a certain time, the automatic removal of weeds 1 is realized, and the cost of manual removal of weeds 1 is reduced. The wire cutting device is composed of a motor 2 and a long wire 3. When the operation is stopped, the long wire 3 is in a stagnant state. When the operation is started, the long wire 3 will rotate at a high speed to achieve a shear force that can cut the weeds 1. The power used by the motor 2 of the wire cutting device is provided by photovoltaic power generation. When the photovoltaic power generation is too much, it is stored in the battery. When it exceeds the battery capacity, it is converted into heat and transmitted to the boiler to burn the weeds 1.

[0042] By arranging a collecting tank under the wire cutting device, the collecting tank is connected to the conveying device, and a weight sensor 10 is arranged on the conveying device. By setting a certain weight value, the conveying device is automatically turned on for conveying when the set weight is reached, so that the weeds 1 are conveyed to the designated trapping device, thereby realizing the organic combination and integration of the equipment; by installing a stepper motor 12 and a pressure roller 13 on the conveying device, the power generated by the weeds 1 moving on the conveying device due to their own gravity is recycled and utilized, and the power is recycled into the battery capacitor of the stepper motor 12, and the stepper motor 12 is used to drive the peristaltic pump to convey the 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, when the weeds 1 grow too fast and exceed the required use, the medicine for inhibiting the growth of the weeds 1 can be sprayed. When the boiler needs a large amount of weeds 1 to burn or the number of red fire ants is too large, resulting in a shortage of weeds 1, the growth agent can be sprayed to promote their growth. By setting a laser sensor 7, the growth status of the weeds 1 is monitored, and the weeds 1 are processed in time to prevent them from eroding and damaging the photovoltaic panels. The red fire ants are gathered together to build nests through the trapping device, and they are caught in one fell swoop to prevent them from gnawing and damaging the power station wires. The mesh barrier cover is coated with delphinium essential oil to prevent the red fire ants from gnawing, thereby reducing the possibility of the red 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 to achieve a cooling effect, reduces the temperature on the back of the photovoltaic panel and absorbs heat. The vaporized refrigerant flows back to the condenser 4, uses the absorbed heat to heat water, turns the water into water vapor and sprays it toward the weed pile 5 through the spray port 18, preheats and dries the weed pile 5, reduces its internal water content and increases its own temperature, which is beneficial for it to burn normally for heating after being sent to the boiler, and is also beneficial for it to attract red fire ants that like high temperatures.

[0045] A semicircular cover 16 is provided on the trapping device, and a spray port 18 is provided on an iron guardrail 17 installed along the semicircular cover 16. The spray ports 18 are dispersedly arranged so that the wind speed of the sprayed water vapor is not large, so the red fire ants will not be scared away, and a high temperature environment is created, so that the red fire ants gather towards the trapping device, thereby preventing and controlling them. The semicircular cover 16 can also play a fixing role on the drawstring mesh barrier cover 6 used by the trapping unit.

[0046] By putting a drawstring mesh barrier 6 on the outside of the weed pile 5, after a period of time, when the number of red fire ants reaches a certain level or may pose a threat, the weed pile 5 can be packed by drawing the rope and sent to the boiler to burn the weeds 1, thereby achieving the reuse of the weeds 1 and increasing the fuel source of the boiler. Since the fuel source of the boiler is the weeds 1, the source is not stable and is affected by the growth habits of the weeds 1 and weather and climate factors, the boiler heating is also unstable. Therefore, the boiler heating is mostly used to supply domestic hot water. On the one hand, the weeds 1 are easy to burn and the energy required for restarting is not large. On the other hand, when there are not many weeds 1 and the demand for hot water is not strong, it can be operated at a low load. At this time, the heat from the combustion of the weeds 1 is mainly used to maintain the temperature of the boiler, and hot water is not supplied to the outside.

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