Integrated system for weed control and red imported fire ant control in photovoltaic power plants Technical Field

[0001] This invention relates to the field of photovoltaic power plant technology, and in particular to an integrated system for weed removal and red imported fire ant control in photovoltaic power plants. Background Technology

[0002] Photovoltaic power plants are one of the most promising renewable energy generation technologies. A photovoltaic power plant mainly consists of photovoltaic panels, controllers, and inverters. The photovoltaic panels absorb solar radiation and convert it into electricity through the photoelectric effect or photochemical effect. Photovoltaic panels are a crucial component of a photovoltaic power plant. When these panels are built on a sloped hillside, weeds often grow on the ground behind them during operation. Allowing these weeds to grow unchecked can erode the back of the panels and block sunlight, thus affecting power generation efficiency. Therefore, managing weeds is a pressing issue. Furthermore, the high temperatures of the power plant's power lines attract red imported fire ants, which can damage the wires.

[0003] Therefore, there is an urgent need to provide an integrated system for weed removal and red imported fire ant control in photovoltaic power plants to solve the problems existing in the above-mentioned technologies. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides an integrated system for weed control and red imported fire ant control in photovoltaic power plants, comprising:

[0006] A wire cutting device is installed below a photovoltaic panel. The wire cutting device is used to cut weeds growing under the photovoltaic panel. The wire cutting device is equipped with a laser sensor for real-time detection of weed growth status, and a spraying component is also provided on the wire cutting device.

[0007] The conveying device has a collection trough at its bottom and one end of the conveying device is connected to the collection trough; the conveying device is inclined and has a power recovery component on it.

[0008] A trapping device is located at the other end of the conveying device, and the elevation of the trapping device is lower than the elevation of the collection tank; a spraying assembly is installed on the trapping device.

[0009] A heat dissipation device is provided, wherein the evaporation end of the heat dissipation device is mounted on the back plate of the photovoltaic panel, the condensation end of the heat dissipation device is correspondingly arranged with the trapping device, and the power recovery component is used to drive the refrigerant flow within the heat dissipation device.

[0010] Preferably, the wire cutting device includes a motor, and a long wire is connected to the output shaft of the motor; the laser sensor is installed on the top of the motor, and multiple spray nozzles are provided on the body of the motor, with the multiple spray nozzles arranged circumferentially along the motor.

[0011] Preferably, the conveying device includes a conveyor belt communicating with the collection trough, the conveyor belt being inclined, and a weight sensor being installed on the conveyor belt; the power recovery component is driven by the conveyor belt.

[0012] Preferably, the conveyor belt is equipped with a one-way partition.

[0013] Preferably, the power recovery component includes a stepper motor, and a pressure roller is connected to the output shaft of the stepper motor. The end of the pressure roller is driven by a peristaltic pump in the heat dissipation device.

[0014] Preferably, the trapping device includes a pile of weeds, and the outer side of the pile of weeds is covered with a drawstring mesh barrier.

[0015] Preferably, the drawstring mesh barrier is provided with a coating to prevent red imported fire ants from biting it.

[0016] Preferably, the spray assembly includes a fixing frame, on which a semi-circular cover is mounted, the semi-circular cover being positioned above the weed pile; an iron guardrail is mounted on the outer wall of the semi-circular cover, the iron guardrail being arranged along the circumference of the semi-circular cover, and multiple spray nozzles are provided on the iron guardrail for spraying water vapor, the multiple spray nozzles being equally spaced along the circumference of the iron guardrail.

[0017] Preferably, the heat dissipation device includes an evaporator and a condenser. The evaporator is installed on the back panel of the photovoltaic panel, and a water heating device is correspondingly provided at the condenser. The water vapor outlet of the water heating device is connected to the spray nozzle. A loop is formed between the evaporator and the condenser through a flexible hose. A peristaltic pump is provided on the flexible hose, and the power recovery component is driven by the peristaltic pump. The outlet end of the condenser is connected to a hot water refrigerant heat exchanger, and the outlet end of the hot water refrigerant heat exchanger is connected to the evaporator.

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

[0019] 1. The integrated system for weed removal and red imported fire ant control in photovoltaic power stations provided by this invention uses a wire cutting device to remove ground weeds under photovoltaic panels, realizing automated weed removal in power stations, preventing weeds from eroding and damaging photovoltaic panels, and reducing the cost of manual weed removal; and when the wire cutting device stops operating, the long wire does not have cutting ability and will not cause harm to pedestrians, improving the safety of the system; the wire cutting device is equipped with a laser sensor, which facilitates the cutting and transportation of weeds to a designated location when they grow to a certain height or need to be used.

[0020] 2. The weeds are transported to the trapping device by their own weight, and the resulting power is recycled to the stepper motor's battery, driving the pressure roller. The pressure roller squeezes the hose, causing the refrigerant inside to release heat in the condenser, thus heating and drying the weed pile. The dried weeds then absorb heat from the photovoltaic panel's backsheet in the evaporator, cooling the panel and improving its efficiency while reducing potential damage. A conveyor system transports the cut weeds to a designated area where they reach high temperatures under solar radiation or due to slow oxidation from the accumulated weeds. The heat transferred from the photovoltaic panel's backsheet to the weed pile also attracts red imported fire ants, eliciting them to gather there for further control. This method prevents red imported fire ants from gnawing on power lines without requiring external materials, reducing the cost of red imported fire ant control in power plants and improving economic efficiency.

[0021] 3. Using wire-cut weeds for red imported fire ant control instead of chemical additives improves environmental benefits, embodies the concept of environmental protection, and reuses the cut weeds, reducing secondary costs of weed treatment and improving the economic efficiency of the power station.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] As shown in Figures 1 and 2, this invention provides an integrated system for weed control and red imported fire ant control in a photovoltaic power station, comprising:

[0028] A wire cutting device is installed below the photovoltaic panel. The wire cutting device is used to cut the weeds 1 growing under 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 component is also provided on the wire cutting device.

[0029] The conveying device has a collection trough at the bottom of the wire cutting device, and one end of the conveying device is connected to the collection trough; the conveying device is set at an incline, and a power recovery component is installed on the conveying device.

[0030] A trapping device is located at the other end of the conveying device, and the elevation of the trapping device is lower than the elevation of the collection tank; a spraying assembly is installed on the trapping device.

[0031] The heat dissipation device has its evaporator end installed on the back of the photovoltaic panel, and its condenser end is correspondingly set with the trapping device. The power recovery component is used to drive the refrigerant flow within the heat dissipation device.

[0032] To further optimize the design, in order to facilitate the 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 multiple spray nozzles 11 are provided on the body of the motor 2, with the multiple spray nozzles 11 arranged around the circumference of the motor 2.

[0033] The scheme is further optimized. The conveying device includes a conveyor belt 8 connected to the collection tank. The conveyor belt 8 is inclined and a weight sensor 10 is installed on the conveyor belt 8. The power recovery component is driven by the conveyor belt 8.

[0034] To further optimize the scheme, a one-way baffle 9 is installed on the conveyor belt 8 to prevent the weeds 1 from being transported in the opposite direction.

[0035] Further optimization of the 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] To further optimize the scheme, the trapping device includes a pile of weeds 5. To facilitate packing the pile of weeds 5, a drawstring mesh barrier cover 6 is provided on the outside of the pile of weeds 5.

[0037] To further optimize the solution and reduce the possibility of red imported fire ants escaping, the drawstring mesh barrier 6 is equipped with a coating to prevent red imported fire ants from biting it. The coating can be made of delphinium oil.

[0038] Further optimizing the scheme, the sprinkler assembly includes a fixed frame 19, on which a semi-circular cover 16 is installed. The semi-circular cover 16 is positioned above the weed pile 5. An iron guardrail 17 is installed on the outer wall of the semi-circular cover 16. The iron guardrail 17 is arranged around the circumference of the semi-circular cover 16. Multiple spray nozzles 18 are provided on the iron guardrail 17. The spray nozzles 18 are used to spray water vapor. The multiple spray nozzles 18 are arranged at equal intervals around the circumference of the iron guardrail 17.

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

[0040] The solution is further optimized. The heat dissipation device includes an evaporator 15 and a condenser 4. The evaporator 15 is installed on the back panel of the photovoltaic panel. A water heating device is installed at the condenser 4. The water vapor outlet of the water heating device is connected to the spray nozzle 18. A loop is formed between the evaporator 15 and the condenser 4 through a hose 14. A peristaltic pump is installed on the hose 14. The power recovery component is driven by the peristaltic pump. The outlet end of the condenser 4 is connected to a hot water refrigerant heat exchanger. The outlet end of the hot water refrigerant heat exchanger is connected to the evaporator 15.

[0041] The integrated system for weed removal and red imported fire ant control in a photovoltaic power station provided by this invention works as follows: A wire cutting device is installed under the photovoltaic panel, and a laser sensor 7 is installed on the wire cutting device to detect the growth status of weeds 1 in real time. The wire cutting device is automatically activated at a certain time to achieve automated removal of weeds 1, reducing the cost of manual weed removal. The wire cutting device consists of a motor 2 and a long wire 3. When the device is not running, the long wire 3 is stationary. When the device is running, the long wire 3 rotates at high speed as the motor 2 starts, thereby achieving the shearing force to 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 exceeds the capacity, it is stored in the battery. When the battery capacity is exceeded, it is converted into heat and sent to the boiler to burn the weeds 1.

[0042] A collection trough is set under the online cutting device, and the collection trough is connected to a conveying device. The conveying device is equipped with a weight sensor 10. By setting a certain weight value, the conveying device will automatically start to transport the weeds 1 to the designated trapping device, thus 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 fed into the battery capacitor of the stepper motor 12. The stepper motor 12 drives a peristaltic pump to deliver 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 nozzle 11 to the online cutting device, when the growth of weeds 1 is too rapid and exceeds the required amount, pesticides that inhibit the growth of weeds 1 can be sprayed. When the boiler needs a large amount of weeds 1 for combustion or when the number of red imported fire ants is too large and the supply of weeds 1 is insufficient, growth promoters can be sprayed to promote their growth. By setting up a laser sensor 7, the growth status of weeds 1 can be monitored, and weeds 1 can be treated in a timely manner to prevent them from eroding and damaging the photovoltaic panels. Red imported fire ants are gathered together to build nests by a trapping device and then caught in one net to prevent them from gnawing and damaging the power station's power lines. The mesh barrier is coated with delphinium oil to prevent red imported fire ants from biting, thereby reducing the possibility of red imported fire ants escaping.

[0044] The refrigerant is delivered 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, reducing the temperature on the back of the photovoltaic panel and absorbing heat. The vaporized refrigerant flows back to the condenser 4, using the absorbed heat to heat water, turning the water into water vapor and spraying it onto the weed pile 5 through the spray nozzle 18. This preheats and dries the weed pile 5, reducing its internal moisture content and increasing its temperature, which is beneficial for it to burn and provide heat normally after being sent to the boiler. It also helps attract red imported fire ants that prefer high temperatures.

[0045] A semi-circular cover 16 is installed on the trapping device. Spray nozzles 18 are provided on the iron guardrail 17 installed along the semi-circular cover 16. The spray nozzles 18 are distributed so that the wind speed of the sprayed water vapor is not high, so as not to scare away the red imported fire ants. At the same time, a high temperature environment is created, which makes the red imported fire ants gather at the trapping device, thereby controlling them. The semi-circular cover 16 also serves to fix the drawstring mesh barrier cover 6 used in the trapping unit.

[0046] By covering the outside of the weed pile 5 with a drawstring mesh barrier 6, after a period of time, when the number of red imported fire ants reaches a certain level or may pose a threat, the weed pile 5 can be bundled up by drawing the rope and sent into the boiler to burn the weeds 1, thus achieving the reuse of the weeds 1 and increasing the boiler's fuel source. Since the boiler's fuel source is the weeds 1, the source is not stable and is affected by the growth habits of the weeds 1 and various weather and climate factors, so the boiler's heating is also unstable. Therefore, the boiler's heating is mostly used to supply domestic hot water. On the one hand, the weeds 1 are easy to burn, and the energy required to restart 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 operate at a low load. At this time, the heat from the burning of the weeds 1 is mainly used to maintain the boiler temperature and not to supply hot water to the outside.

[0047] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
