[0017] 1. The photovoltaic power generation device of the present invention is provided with blocking ropes. Several groups of blocking ropes are laid in parallel above the solar cell panels. Since the blocking ropes are relatively thin, they will not block the solar cell panels from absorbing light energy. The blocking ropes can block foreign objects such as fallen leaves and plastic bags from the outside. At the same time, they can effectively block heavier and larger foreign objects blown up by strong winds, thereby reducing damage to the equipment. At the same time, they can also block sticky foreign objects, thereby reducing the problem of contamination of the solar cell panels, which makes it difficult to clean up later, and improving the service life and power generation efficiency of the solar cell panels.

[0018] 2. The photovoltaic power generation device of the present invention has a winding wheel and a blocking rope structure.

The thin rope is used to prevent large debris from damaging the solar panel without affecting the solar panel's absorption of solar energy. When night falls, the servo motor is started to drive the winding wheel to rotate in the opposite direction so that several groups of flat belts move to the top of the solar panel. With the wide, flat and flat setting of the flat belt, the top of the solar panel can be effectively blocked completely, greatly reducing the problem of a series of foreign objects such as fallen leaves and bird droppings polluting the solar panel, thereby reducing the complexity of subsequent cleaning.

[0019] 3. The photovoltaic power generation device of the present invention is provided with a water storage tank and a water pump, and the flat belt is set as a hollow structure, and a water spray assembly is arranged thereon, so that the cleaning liquid in the water storage tank can be sprayed to the surface of the solar cell panel through the water spray assembly, thereby achieving the cleaning work of the surface of the solar cell panel, thereby improving the solar energy collection effect of the solar cell panel.

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0029] Embodiment of the present invention: A photovoltaic power generation device with a protective structure, such as Figure 1-6 As shown, it includes a driving base 1, a solar panel 2 is fixedly installed on the driving end of the driving base 1, a photoresistor is fixedly installed on the top of the solar panel 2, a support frame 5 located above the solar panel 2 is fixedly installed on one side of the driving base 1, storage rods 3 extending in the longitudinal direction are fixedly installed at both ends of the support frame 5, a plurality of blocking ropes 4 arranged parallel to each other are connected between the two storage rods 3, and two symmetrically arranged steering rods 7 are fixedly installed on both sides of the support frame 5, the steering rods 7 are located above the storage rods 3, and the blocking ropes 4 on both sides are steered via the steering rods 7.

[0030] When working, the driving base 1 is controlled by the photoresistor, and the driving base 1 is used to drive the solar panel 2 to rotate in multiple directions, thereby realizing the automatic light-chasing effect. When the solar panel 2 is working, several groups of blocking ropes 4 are laid in parallel on the top. Since the blocking ropes 4 are thin, they will not block the absorption of light energy. The blocking ropes 4 can block foreign objects such as fallen leaves and plastic bags from the outside. At the same time, they can effectively block heavier foreign objects blown up by strong winds, reducing damage to the equipment. At the same time, they can also block sticky foreign objects, reducing the pollution of the solar panel 2, which makes it difficult to clean up later.

[0031] like Figures 1 to 4 As shown, the inner side of the storage rod 3 on each side is rotatably connected to a plurality of winding wheels 12, one end of the winding wheel 12 is fixedly installed with a servo motor, and the two ends of the blocking rope 4 are respectively fixedly connected to the two winding wheels 12 symmetrically arranged on both sides, and the blocking rope 4 is divided into two sections, a flat belt 10 and a thin rope 11.

[0032] During operation, in conjunction with the structural setting of the winding wheel 12 and the blocking rope 4, when working normally during the day, the servo motor is started to rotate the winding wheel 12, so that the thin rope 11 is partially laid parallel to the solar panel 2, and the slender thin rope 11 is used to prevent large debris from damaging the solar panel 2. When night comes, the servo motor is started to drive the winding wheel 12 to rotate in the opposite direction, so that several groups of flat belts 10 move to the top of the solar panel 2. In conjunction with the wide, flat and flat setting of the flat belt 10, the top of the solar panel 2 can be effectively blocked, which greatly reduces the problem of a series of foreign objects such as fallen leaves and bird droppings polluting the solar panel 2, thereby reducing the complexity of subsequent cleaning.

[0033] like Figure 1 to Figure 2 As shown, a water tank 4 is arranged below one of the storage rods 3, a through hole 13 is provided at one end of the winding wheel 12 above the water tank 4, a transmission pipe is fixedly connected between the water tank 4 and the storage rod 3 above it, a water pump is fixedly installed on the inner side of the water tank 8, the water pump is fixedly connected to the transmission pipe, and a booster pump 14 is fixedly installed on the inner side of the storage rod 3, and a centralizing groove is provided on the inner side of the storage rod 3, the storage rod 3 is connected with several groups of through holes 13 of the winding wheel 12 through the centralizing groove, and the output end of the booster pump 14 is connected with the centralizing groove, the flat belt 10 has a hollow structure inside, and the end connected with the winding wheel 12 is connected with the through hole 13, and a plurality of water outlet components are arranged at the bottom of the flat belt 10 along its length direction.

[0034] During operation, the water pump in the water tank 8 is started, and the water pump draws out the cleaning liquid in the water tank 8 and sends it to the pressure pump 14 for pressurization through the transmission pipe. The cleaning liquid then passes through the concentrated groove of the storage rod 3 and the through hole 13 on each winding wheel 12 and is input into the hollow cavity of the flat belt 10, so as to inject the cleaning liquid into the flat belt 10, and the cleaning liquid moves along the flat belt 10 to the top of the solar panel 2, and then is sprayed outward from the water outlet component to clean the surface of the solar panel 2. At the same time, with the setting of the pressure pump 14, the water outlet pressure of the cleaning liquid can be increased to ensure a strong cleaning effect, thereby realizing the function of absorbing solar energy on the outer surface of the solar panel 2 and ensuring the maximum collection effect of the solar panel 2.

[0035] like Figure 4 As shown, the water outlet assembly includes a water spray head 18, a hollow slide rod 17 is fixedly installed on the top of the water spray head 18, and the slide rod 17 is slidably connected to the flat belt 10, the slide rod 17 extends into the hollow cavity of the flat belt 10, and a plurality of groups of oblique water outlet holes 19 are opened on the outside of the water spray head 18, a plurality of groups of inner grooves are opened at the bottom end of the flat belt 10, the water spray head 18 is located in the inner groove, and the flat belt 10 is made of elastic material.

[0036] During operation, in conjunction with the structural setting of the water spray head 18, the cleaning liquid in the hollow cavity of the flat belt 10 enters the water spray head 18 from the slide bar 17, and finally sprays outward from the bottom of the water spray head 18 and the oblique water outlet 19 to achieve the cleaning of the solar panel 2. The water flow sprayed from the side will rotate the water spray head 18, allowing the sprayed cleaning liquid to spread more comprehensively and widely, further improving the cleaning effect. Since the flat belt 10 is made of elastic material, when the hollow cavity inside it is not squeezed by the high-pressure cleaning liquid, an inner groove that is concave inward will be formed inside it. The setting of the inner groove allows the water spray head 18 to be recycled into the inner groove when not in use, so that the recovery work of the blocking rope 4 can proceed normally. When it is necessary to spray the cleaning liquid, the high-pressure cleaning liquid inside the flat belt 10 will squeeze the inner groove and the slide bar 17, so that the surface of the inner groove becomes flat, and the slide bar 17 slides downward at the same time, so that the high-pressure cleaning liquid can be sprayed out from the oblique water outlet 19.

[0037] like Figures 1 to 3 As shown, the top end of the flat belt 10 is concave along its length direction, and a penetration hole is opened at the top end of the concave flat belt 10. A collecting box is fixedly installed on one side of the water tank 8, and the top end of the collecting box is open. A filter screen 9 is fixedly installed on one side of the water tank 8, and the filter screen 9 is located above the collecting box.

[0038] During operation, with the structural setting of the flat belt 10 and the opening of the penetration holes, the cleaning liquid in the hollow cavity of the flat belt 10 will penetrate upward from the penetration holes and accumulate in the concave part, so that foreign matter falling on the flat belt 10 at night will not adhere to the flat belt 10, but stay on the surface of the cleaning liquid, ensuring the cleanliness of the surface of the flat belt 10. At the same time, when the flat belt 10 is recovered, with the setting of the turning rod 7 and the collection box on one side of the water storage tank 8, the water flow accumulated above can be recovered into the water storage tank 8, so as not to waste water resources. At the same time, with the setting of the filter net 9, the water can be filtered, and the collection box at the same time can also collect rainwater, realizing the function of recycling.

[0039] like Figure 3 As shown, a connecting rod is slidably connected to the inner side of the penetration hole, a floating ball 22 is fixedly installed on the top end of the connecting rod, and a squeezing pad 23 is fixedly installed on the bottom end of the connecting rod. The squeezing pad 23 is made of elastic material.

[0040] During operation, in conjunction with the setting of the float 22, as the water level above the flat belt 10 rises, the connecting rod and the float 22 will float up. When the water level is about to be higher than the highest point of the flat belt 10, the squeezing pad 23 will float to the highest point to block the penetration hole, so that the cleaning liquid will not penetrate too much, reducing the problem of resource waste.

[0041] like Figures 1 to 3 As shown, a deformation pad 20 is fixedly installed at both ends of the flat belt 10, and the deformation pad 20 is made of elastic material. A group of magnets 21 is fixedly installed at both ends of the flat belt 10, and the magnet 21 is located at the connection between the deformation pad 20 and the flat belt 10.

[0042] During operation, with the setting of the magnet 21, two adjacent groups of flat belts 10 can be adsorbed to each other, so that several groups of flat belts 10 can be connected into a whole, effectively reducing the gaps between the flat belts 10, and reducing the probability of foreign matter passing through the gaps and falling into the outside of the solar cell panel 2. At the same time, it can ensure a more stable and horizontal arrangement of the flat belts 10, so that the cleaning liquid above can better cover the top of the flat belts 10. At the same time, with the setting of the deformable pad 20, it can provide isolation and buffering for protecting the magnet 21.

[0043] like Figures 2 to 5As shown, a plurality of movable grooves 16 are provided on the inner side of the storage rod 3 away from the water tank 8, a hand bellows 15 is fixedly installed on the inner side of the movable groove 16, a one-way valve 24 is fixedly installed on the output end of the hand bellows 15, and a one-way valve 25 is fixedly installed on the outer side of the hand bellows 15, a power assembly is provided at the bottom end of the hand bellows 15, a through hole 13 is provided on the winding wheel 12 on the storage rod 3, the output end of the hand bellows 15 is connected with the through hole 13 of the winding wheel 12, a hollow groove is provided inside the thin rope 11, the winding wheel 12 is connected with the hollow groove inside the thin rope 11 through the through hole 13, and a plurality of air outlet holes 29 connected with the hollow groove are provided on the top surface of the thin rope 11.

[0044] During operation, during normal daytime work, the power component drives the hand bellows 15 to perform repeated squeezing and releasing operations, so that air can be blown into the thin rope 11. The setting of the one-way valve 1 24 and the one-way valve 2 25 allows the airflow in the thin rope 11 to always be in an outward spraying state, and combined with the air outlet 29 opened on the outside of the thin rope 11, the airflow can be effectively sprayed outward, so that foreign objects falling from the outside will be affected by the blowing force of the airflow before falling on the blocking rope 4, thereby staying away from the equipment. Through this setting, the problem of foreign objects falling on the top of the solar panel 2 and causing low energy absorption efficiency is further reduced.

[0045] like Figures 1 to 5 As shown, the power assembly includes a pneumatic fan 6, a transmission rod 28 is fixedly installed on the top of the pneumatic fan 6, the transmission rod 28 is rotatably connected to the bottom end of the storage rod 3, a top plate 27 is fixedly installed on the outer side of the top end of the transmission rod 28, a power rope 26 is connected between the bottom ends of the hand bellows 15, the power rope 26 and the top plate 27 are located in the same horizontal plane, and a spring is fixedly connected to the outer side of the hand bellows 15.

[0046] During operation, when wind blows from the outside, the pneumatic fan 6 will be driven to rotate, thereby driving the transmission rod 28 and the top plate 27 to rotate. When the side surface of the head end of the rotating top plate 27 contacts the power rope, the power rope 26 will be pushed out to one side, so that the hand bellows 15 are merged to blow air outward. At this time, the spring on the hand bellows 15 is squeezed, and as the top plate 27 continues to rotate, the top plate 27 separates from the power rope 26, so that the squeezing force on the power rope 26 disappears, and then with the restoring elastic force of the spring, the hand bellows 15 can return to its original position and inhale air at the same time. Through this arrangement, repeated blowing work is achieved without consuming electricity, and because foreign objects generally move to high altitudes and fall onto the solar panel 2 under the carry of strong winds, this arrangement can work quickly in strong winds, further improving the effect of the equipment in removing and isolating foreign objects.

[0047] like Figures 3 to 6As shown, an inner recessed groove is provided on the outer side of the top plate 27. When the top plate 27 rotates and contacts the power rope 26, the power rope 26 is inserted into the inner recessed groove to avoid misalignment between the power rope 26 and the top plate 27 during compression.

[0048] The air outlet 29 is provided with an expansion pad 30, which is made of elastic material and has a plurality of holes. When working, when the airflow acts on the string 11, the expansion pad 30 will expand outward, so that the air outlet 29 opens and sprays outward. When the spraying is finished, the expansion pad 30 will return to its original position by itself with the elastic force of the expansion pad 30. Through this arrangement, the air pressure can first fill the entire string 11, and then push outward, so that the air pressure can spray out the outside of the entire string 11, avoiding the problem that only the end of the string 11 sprays high-speed airflow, resulting in inadequate cleaning effect.

[0049] The whole process is as follows: when working, the driving base 1 is controlled by the photoresistor, and the driving base 1 is used to drive the solar panel 2 to rotate in multiple directions, thereby realizing the automatic light-chasing effect. When the solar panel 2 is working, several groups of blocking ropes 4 are laid in parallel on the top. Since the blocking ropes 4 are thin, they will not block the absorption of light energy. The blocking ropes 4 can block foreign objects such as fallen leaves and plastic bags from the outside. At the same time, they can effectively block heavier foreign objects blown up by strong winds, reducing damage to the equipment. At the same time, they can also block sticky foreign objects, reducing the pollution of the solar panel 2, which makes it difficult to clean up later. During operation, with the structural setting of the winding wheel 12 and the blocking rope 4, when working normally during the day, the servo motor is started to rotate the winding wheel 12, and when the thin rope 11 is partially laid parallel to the solar panel 2, the thin rope 11 is used to prevent large debris from damaging the solar panel 2; when night comes, the servo motor is started to drive the winding wheel 12 to rotate in the opposite direction, so that several groups of flat belts 10 move to the top of the solar panel 2. With the wide, flat and flat setting of the flat belt 10, the top of the solar panel 2 can be effectively blocked, greatly reducing the problem of a series of foreign objects such as fallen leaves and bird droppings contaminating the solar panel 2, thereby reducing the complexity of subsequent cleaning. When the flat belt 10 is working, the water pump in the water storage tank 8 is started to inject cleaning liquid into the flat belt 10, so that the cleaning liquid moves along the flat belt 10 to the top of the solar panel 2, and then sprays outward from the water outlet component, so that the surface of the solar panel 2 can be cleaned. At the same time, in conjunction with the setting of the pressure pump 14, the water outlet pressure of the cleaning liquid can be increased to ensure a strong cleaning effect, thereby realizing the function of cleaning the outer surface of the solar panel 2 and ensuring the maximum collection effect of the solar panel 2. When the water outlet assembly is working, in conjunction with the structural setting of the water spray head 18, when the cleaning liquid is sprayed outward, the cleaning liquid will be sprayed outward from the bottom end of the water spray head 18 and the oblique water outlet hole 19, and the water flow sprayed from the side will make the water spray head 18 rotate, so that the sprayed cleaning liquid spreads more comprehensively and widely, thereby further improving the cleaning effect. The setting of the inner groove of the flat belt 10 allows the water spray head 18 to retract into the inner groove when not in use, so that the recovery work of the blocking rope 4 can proceed normally. When working, in conjunction with the structural setting of the flat belt 10 and the opening of the penetration hole, the cleaning liquid will penetrate upward through the penetration hole and accumulate in the concave part, so that foreign matter falling on the flat belt 10 at night can stay on the cleaning liquid and will not adhere to the surface of the flat belt 10, ensuring the cleanliness of the outer side of the flat belt 10. At the same time, when the flat belt 10 is recovered, the setting of the turning rod 7 and the collection box on one side of the water storage tank 8 can make the water flow accumulated above be recovered into the water storage tank 8, so as not to waste water resources, and at the same time, the setting of the filter net 9 can filter the water. The extended collection box can also collect rainwater, thereby realizing the function of recycling.When the flat belt 10 is working, in conjunction with the setting of the float 22, as the water level above the flat belt 10 rises, it will float up with the connecting rod and the float 22. When the water level is about to be higher than the highest point of the flat belt 10, the squeeze pad 23 will float to the highest point to block the penetration hole, so that the cleaning liquid will not penetrate too much, reducing the problem of resource waste. During the operation of the flat belt 10, in conjunction with the setting of the magnet 21, two adjacent groups of flat belts 10 can be adsorbed on each other, so that several groups of flat belts 10 can be connected into a whole, effectively reducing the gaps between the flat belts 10, reducing the probability of foreign matter falling through the gaps into the surface of the solar panel 2, and at the same time ensuring a more stable and horizontal arrangement of the flat belt 10, so that the cleaning liquid above can better cover the top of the flat belt 10, and in conjunction with the setting of the deformable pad 20, it can provide isolation and buffering for protecting the magnet 21. When the thin rope 11 is working, the power component drives the hand bellows 15 to perform repeated squeezing and releasing operations, so that air can be blown into the thin rope 11. The setting of the one-way valve 1 24 and the one-way valve 2 25 allows the airflow in the thin rope 11 to always be in an outward spraying state. Combined with the air outlet 29 opened on the outside of the thin rope 11, the airflow can be effectively sprayed outward, so that foreign objects falling from the outside will be affected by the blowing force of the airflow before falling on the blocking rope 4, thereby staying away from the equipment. Through this setting, the problem of foreign objects falling on the top of the solar panel 2 and causing low energy absorption efficiency is further avoided. During the operation of the thin rope 11, when the wind blows from the outside, it will blow the wind-driven fan 6 to rotate, thereby driving the transmission rod 28 and the top plate 27 to rotate. The rotating top plate 27 will push the power rope 26 to one side, so that the hand bellows 15 closes and blows out air. Then, as the top plate 27 continues to rotate, the tension on the power rope 26 disappears, and then with the elastic force of the spring, the hand bellows 15 can return to its original position and inhale air at the same time. Through this setting, repeated blowing work is achieved without consuming electricity. And because foreign matter generally moves to high altitude and falls onto the solar panel 2 under the carry of strong winds, this setting can work quickly in strong winds, further improving the effect of the equipment in removing and isolating foreign matter. When the thin rope 11 is working, when the airflow acts on the thin rope 11, the expansion pad 30 will expand outward, and its own air outlet 29 will open and spray outward. When the spraying is finished, with the elastic force of the expansion pad 30 itself, the expansion pad 30 will return to its original position. Through this setting, the air pressure can first fill the entire thin rope 11, and then spray outward, so that the air pressure can spray out on the outside of the entire thin rope 11, avoiding the problem of only high-speed airflow spraying out of the end of the thin rope 11, resulting in inadequate cleaning effect.
