When the surface of the photovoltaic panel is covered with impurities, the proportion of light absorbed will decrease, resulting in a decrease in power generation. Keeping the surface of the photovoltaic panel clean and avoiding the attachment of impurities can ensure the efficient operation of the system, maximizing power generation and economic benefits.

[0011] According to the above technical solution, the cleaning device further includes a push rod, a rotating pressure rod, a hydraulic cylinder, a hydraulic rod, and a water collecting frame.

The hydraulic rod is slidably installed on the inner wall of the hydraulic cylinder. The water collecting frame is fixedly installed on one side of the support platform away from the photovoltaic panel.

The fixing plate is fixedly installed on one side of the elastic support rod close to the limiting block. When the elastic support rod rotates away from the support column, the elastic support rod will extend to support the ground, strengthening the supporting force of the support column. When the rainfall is too large on a rainy day, strong winds will accompany it. When the wind force is too large, the supporting force of the support column will be insufficient, causing the support column to be blown and tilted to one side. The tilting of the support column to one side will damage the photovoltaic panel and cause economic losses.

[0015] A usage method of an efficient solar photovoltaic direct-drive heat collection and power generation integrated device. Using the above-mentioned efficient solar photovoltaic direct-drive heat collection and power generation integrated device, it includes the following steps;

[0016] Step 1: Fix the support column at a higher position. The device is powered on by detecting sunlight through the light sensor. When the device is powered on, its own program starts, driving the support platform to rotate following the sunlight. The rotation of the support platform drives the photovoltaic panel to rotate following the sunlight. When the photovoltaic panel is illuminated, it generates electrical energy, and the generated electrical energy enters the storage battery for collection. The heat energy generated by the illumination enters the heat collector for storage;

[0017] Step 2: When the support platform rotates to the left, it drives the sliding frame to move. The movement of the sliding frame causes the telescopic rack to mesh with the fixed gear, so the left telescopic rack slides towards the direction of the photovoltaic panel. The movement of the sliding frame drives the baffle to move, and the movement of the baffle drives the buffer plate to move, and the movement of the buffer plate protects the photovoltaic panel;

[0018] Step 3: The movement of the crossbar pushes the wedge block to move upward. The upward movement of the wedge block pushes the telescopic rack to move upward. When the telescopic rack moves upward, it disengages from the contact with the fixed gear. When the buffer plate hits an object, the support platform continues to rotate and cannot drive the buffer plate to move.

[0019] The present invention provides an efficient solar photovoltaic direct drive heat collection and power generation integrated device and its usage method. It has the following beneficial effects:

[0020] (1) In this invention, the movement of the baffle drives the movement of the buffer plate, and the movement of the buffer plate protects the photovoltaic panel, preventing the photovoltaic panel from hitting other larger objects during rotation and causing damage to the photovoltaic panel. When the buffer plate hits other larger objects, the buffer plate will move towards the direction of the baffle to absorb the impact force. The impact may cause the photovoltaic panel to crack or even make the photovoltaic panel unable to work properly. This not only loses the power generation capacity but also may affect the service life of the equipment. When the telescopic rack moves upward, it drives the pressing plate to move, and the movement of the pressing plate squeezes the control end of the button, causing the support platform to stop rotating, preventing the buffer plate from exerting a large force on the driving device between the support platform and the support column when hitting an object and damaging the driving device. If the driving device fails, the photovoltaic panel cannot rotate normally along the predetermined trajectory, which may lead to a decrease in system efficiency or a complete stop of operation.

[0021] (2) In this invention, when the rotating gear rotates downward, it drives the elastic telescopic rod to rotate downward. When the elastic telescopic rod rotates downward, it drives the scraper to move. The movement of the scraper cleans the surface of the photovoltaic panel, preventing impurities from adhering to the surface of the photovoltaic panel and reducing the power generation and heat collection efficiency of the photovoltaic panel. When the surface of the photovoltaic panel is covered with impurities, the proportion of light absorbed will decrease, resulting in a decrease in power generation. Keeping the surface of the photovoltaic panel clean and avoiding the attachment of impurities can ensure the efficient operation of the system, maximizing power generation and economic benefits. When the rotating lever rotates, it pushes the hydraulic rod to slide inside the hydraulic cylinder. When the hydraulic rod slides inside the hydraulic cylinder, it pushes the liquid inside the hydraulic cylinder to be discharged through the water outlet via the first hose. The discharge of the liquid from the water outlet wets the surface of the scraper, enhancing the cleaning of the surface of the photovoltaic panel. Photovoltaic panels are usually protected by special coatings, and scratching may damage these coatings, making the surface of the photovoltaic panel prone to pollution and wear, thus affecting its long-term performance. Sprinkling water can not only enhance the cleaning of the photovoltaic panel but also protect the photovoltaic panel from being scratched.

[0022] (3) In this invention, when the rotating lever squeezes the hydraulic rod, the rotating lever pushes the rotating push rod to move. When the rotating push rod moves, it pushes the scraping rod to move. The movement of the scraping rod cleans the surface of the filter screen, preventing impurities from adhering to the surface of the filter screen and blocking the surface of the filter screen, preventing rainwater from being collected well. When the elastic support rod rotates away from the support column, the elastic support rod will extend to support the ground, enhancing the supporting force on the support column. When the rainfall is excessive on a rainy day, strong winds may accompany it. When the wind force is too strong, the supporting force of the support column may be insufficient, causing the support column to be blown and tilted to one side. The tilting of the support column to one side may damage the photovoltaic panel and cause economic losses. Brief Description of the Drawings

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0033] Please refer to Figures 1-8 , an embodiment of the present invention is: a high-efficiency solar photovoltaic direct-drive heat collection and power generation integrated device, including a support column 1, a driving device is fixedly installed at the top of the support column 1, an output end of the driving device is fixedly installed with a support platform 2, one end of the support platform 2 is fixedly installed with a photovoltaic panel 3, a collector 4 is fixedly installed on a side of the photovoltaic panel 3 away from the support platform 2, a storage battery is fixedly installed on the top of the support platform 2, a light sensing device is arranged at the other end of the support platform 2, and a protection device is further arranged on the top of the support platform 2

[0034] The protection device includes a fixed gear 5, a sliding frame 6, a baffle 7, a buffer plate 8, a cross bar 9, an inclined block 10, a telescopic rack 11, a pressing plate 12 and a button 13. The fixed gear 5 is fixedly installed on the circumferential surface of the support column 1. The sliding frame 6 is slidably installed on both sides of the support table 2. The telescopic rack 11 is slidably installed on the inner wall of the sliding frame 6. The baffle 7 is fixedly installed on the side of the sliding frame 6 away from the support table 2. The buffer plate 8 is fixedly installed on the side of the baffle 7 away from the sliding frame 6. One end of the cross bar 9 is fixedly installed at the bottom of the buffer plate 8. The inclined block 10 is fixedly installed on the side of the telescopic rack 11 close to the cross bar 9. The other end of the cross bar 9 contacts the inclined block 10. The pressing plate 12 is fixedly installed at the bottom of the telescopic rack 11. The button 13 is arranged at the bottom of the support table 2. When the buffer plate 8 hits something larger, the buffer plate 8 will move towards the baffle 7, absorbing the force received by the impact. The impact may cause the photovoltaic panel 3 to break, or even cause the photovoltaic panel 3 to fail to work properly. This not only loses the power generation capacity, but also may affect the service life of the equipment.

[0035] The button 13 is electrically connected to the driving device. The control end of the button 13 contacts the pressing plate 12. The side of the inclined block 10 close to the cross bar 9 is set as an inclined plane. The reason for setting the side of the inclined block 10 close to the cross bar 9 as an inclined plane is to enable the cross bar 9 to better push the inclined block 10 to move when the cross bar 9 moves. The cross bar 9 contacts the inclined plane of the inclined block 10.

[0036] A first spring is arranged between the buffer plate 8 and the baffle 7. The reason for arranging the first spring is to enable the buffer plate 8 to play a buffering role when being impacted. A second spring is arranged between the telescopic rack 11 and the sliding frame 6. The reason for arranging the second spring is to push the telescopic rack 11 back to its original position. The telescopic rack 11 meshes with the fixed gear 5.

[0037] A usage method of an efficient solar photovoltaic direct drive heat collection and power generation integrated device, using the above-mentioned efficient solar photovoltaic direct drive heat collection and power generation integrated device, includes the following steps;

[0038] Step 1: Fix the support column 1 at a higher position. The device is powered on by detecting sunlight through a light sensing device. When the device is powered on, its own program is started to drive the support table 2 to rotate following the sunlight. The rotation of the support table 2 drives the photovoltaic panel 3 to rotate following the sunlight. The photovoltaic panel 3 generates electric energy when exposed to light. The generated electric energy enters the storage battery for collection, and the heat energy generated by the light enters the heat collector 4 for storage;

[0039] Step 2: When the support table 2 rotates to the left, it drives the sliding frame 6 to move. The movement of the sliding frame 6 causes the telescopic rack 11 to mesh with the fixed gear 5. Then the telescopic rack 11 on the left slides towards the direction of the photovoltaic panel 3. The movement of the sliding frame 6 drives the baffle 7 to move. The movement of the baffle 7 drives the buffer plate 8 to move. The movement of the buffer plate 8 protects the photovoltaic panel 3;

[0040] Step 3: The movement of the cross bar 9 will push the inclined block 10 upward. The upward movement of the inclined block 10 will push the telescopic rack 11 upward. When the telescopic rack 11 moves upward, it will disengage from the fixed gear 5. Then, when the buffer plate 8 hits an object, the support platform 2 continues to rotate and cannot drive the buffer plate 8 to move.

[0041] During the operation of this embodiment: The support column 1 is fixed at a relatively high position. The photovoltaic heat collection device is powered on by detecting sunlight through the light sensing device. When the photovoltaic heat collection device is powered on, the program of the driving device is started. When the driving device starts, it will drive the support platform 2 to rotate following the sunlight. The rotation of the support platform 2 will drive the photovoltaic panel 3 to rotate following the sunlight. When the photovoltaic panel 3 is illuminated, electrical energy will be generated. The generated electrical energy will enter the storage battery for collection, and the heat energy generated by the illumination will enter the heat collector 4 for storage. When the photovoltaic panel 3 is installed facing north, the support platform 2 will rotate from right to left when illuminated. After the sun goes down, the support platform 2 will drive the photovoltaic panel 3 back to the right side and continue to collect sunlight when the sun rises the next day. When the support platform 2 rotates to the left, it will drive the sliding frame 6 to move. The movement of the sliding frame 6 will cause the telescopic rack 11 to engage with the fixed gear 5. Then, the left telescopic rack 11 will slide towards the direction of the photovoltaic panel 3. The movement of the sliding frame 6 will drive the baffle 7 to move. The movement of the baffle 7 will drive the buffer plate 8 to move. The movement of the buffer plate 8 will protect the photovoltaic panel 3 and prevent the photovoltaic panel 3 from being damaged when it hits other large objects during rotation. When the buffer plate 8 hits other large objects, the buffer plate 8 will move towards the direction of the baffle 7 to absorb the impact force. When the buffer plate 8 moves, it will push the cross bar 9 to move. The movement of the cross bar 9 will contact the inclined surface of the inclined block 10. Then, the movement of the cross bar 9 will push the inclined block 10 upward. The upward movement of the inclined block 10 will push the telescopic rack 11 upward. When the telescopic rack 11 moves upward, it will disengage from the fixed gear 5. Then, when the buffer plate 8 hits an object, the support platform 2 continues to rotate and cannot drive the buffer plate 8 to move. When the telescopic rack 11 moves upward, it will drive the pressing plate 12 to move. The movement of the pressing plate 12 will squeeze the control end of the button 13, causing the support platform 2 to stop rotating, and preventing the buffer plate 8 from exerting a large force on the driving device between the support platform 2 and the support column 1 when hitting an object, thus damaging the driving device.

[0042] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a cleaning device for cleaning the photovoltaic panel 3 and a supporting device for strengthening the support of the support column 1 are further provided on the support table 2.

The elastic telescopic rod 144 is fixedly installed at one end of the rotating gear 142 away from the support table 2. The scraper 145 is fixedly installed at one end of the elastic telescopic rod 144 away from the support table 2. When the rotating gear 142 rotates downward, it will drive the elastic telescopic rod 144 to rotate downward. When the elastic telescopic rod 144 rotates downward, it will drive the scraper 145 to move. When the scraper 145 moves, it will clean the surface of the photovoltaic panel 3, avoiding impurities adhering to the surface of the photovoltaic panel 3 and reducing the power collection and heat collection efficiency of the photovoltaic panel 3. When the surface of the photovoltaic panel 3 is covered with impurities, the proportion of light absorbed will decrease, resulting in a decrease in power generation. Keeping the surface of the photovoltaic panel 3 clean and avoiding the attachment of impurities can ensure the efficient operation of the system and maximize power generation and economic benefits.

When the liquid is discharged from the water outlet, it will wet the surface of the scraper 145 and strengthen the cleaning of the surface of the photovoltaic panel 3. The photovoltaic panel 3 is usually protected by a special coating. Scratching may damage these coatings, causing the surface of the photovoltaic panel 3 to be easily contaminated and worn, thus affecting its long-term performance. Sprinkling water can not only strengthen the cleaning of the photovoltaic panel 3 but also protect the photovoltaic panel 3 from being scratched.

[0044] The inner wall of the rack frame 141 is provided with an upper rack and a lower rack. The rotating gear 142 meshes with the rack frame 141. A drain port is opened on one side of the water collecting frame 149 away from the support platform 2.

The elastic support rod 158 is rotatably installed on the circumferential surface of the support column 1. The vertical rod 1593 is fixedly installed at the bottom of the circular ring 157. The sliding block 1592 is slidably installed on the circumferential surface of the support column 1. The limiting block 1591 is slidably installed on the circumferential surface of the support column 1. The fixing plate 159 is fixedly installed on the side of the elastic support rod 158 close to the limiting block 1591. When the elastic support rod 158 rotates away from the support column 1, the elastic support rod 158 will elongate to support the ground, strengthening the support force for the support column 1. When the rainfall is too large on a rainy day, strong winds will accompany it. When the wind force is too large, the support force of the support column 1 will be insufficient, causing the support column 1 to be blown and tilted to one side. The support column 1 tilting to one side will cause damage to the photovoltaic panel 3 and result in economic losses.

[0046] A second torsion spring is provided between the elastic support rod 158 and the support column 1. The second torsion spring is provided to push the elastic support rod 158 to rotate when the limit of the elastic support rod 158 is released. A drain groove is formed at the bottom of the inner wall of the water collecting frame 149. A third spring is provided between the sliding plate 154 and the water collecting frame 149. The third spring is provided to drive the sliding plate 154 back to its original position. A water outlet is formed at the top of the sliding plate 154. The circular plate 155 is in contact with the inner wall of the water outlet. A fourth spring is provided between the ring 157 and the support column 1. The fourth spring is provided to drive the ring 157 back to its original position. An inclined surface is provided on the side of the vertical rod 1593 and the sliding block 1592 that are close to each other. The inclined surface provided on the vertical rod 1593 and the sliding block 1592 is to facilitate the vertical rod 1593 to push the sliding block 1592 to move. An inclined surface is provided on the side of the limiting block 1591 and the sliding block 1592 that are close to each other. The inclined surface provided on the limiting block 1591 and the sliding block 1592 is to facilitate the sliding block 1592 to push the limiting block 1591 to move. A fixing groove is formed at the top of the fixing plate 159. The limiting block 1591 is in contact with the inner wall of the fixing groove. A fifth spring is provided between the limiting block 1591 and the support column 1. The fifth spring is provided to drive the limiting block 1591 back to its original position.

[0047] During the operation of this embodiment: when the sliding frame 6 moves, it will drive the rack frame 141 to move. When the rack frame 141 moves, it will engage with the rotating gear 142. Then, the rack frame 141 will drive the rotating gear 142 to rotate. When the rack frame 141 moves, the rotating gear 142 will first contact the lower rack, and then the lower rack will drive the rotating gear 142 to rotate downward. The downward rotation of the rotating gear 142 will drive the elastic telescopic rod 144 to rotate downward, and the downward rotation of the elastic telescopic rod 144 will drive the scraper 145 to move. The movement of the scraper 145 will clean the surface of the photovoltaic panel 3, preventing impurities from adhering to the surface of the photovoltaic panel 3 and reducing the power generation and heat collection efficiency of the photovoltaic panel 3. When the rack frame 141 continues to move, the upper rack will engage with the rotating gear 142, and then the upper rack will drive the rotating gear 142 to rotate upward. The upward rotation of the rotating gear 142 will drive the elastic telescopic rod 144 and the scraper 145 back to their original positions. When it rains outside the device, the rainwater will enter the water collection frame 149 for collection. When the rotating gear 142 rotates downward, it will drive the push rod 143 to rotate upward. The upward rotation of the push rod 143 will push the rotating pressure rod 146 to rotate, and the rotation of the rotating pressure rod 146 will store energy in the first torsion spring. The rotation of the rotating pressure rod 146 will push the hydraulic rod 148 to slide into the hydraulic cylinder 147. The sliding of the hydraulic rod 148 into the hydraulic cylinder 147 will push the liquid inside the hydraulic cylinder 147 to be discharged through the water outlet via the first hose. The discharge of the liquid from the water outlet will wet the surface of the scraper 145, enhancing the cleaning of the surface of the photovoltaic panel 3. When the thrust of the push rod 143 on the rotating pressure rod 146 is released, the first torsion spring will drive the rotating pressure rod 146 back to its original position. The return of the rotating pressure rod 146 to its original position will pull the hydraulic rod 148 back to its original position, and the return of the hydraulic rod 148 to its original position will pump the liquid inside the water collection frame 149 into the hydraulic cylinder 147.

[0048] When the rotating pressure rod 146 squeezes the hydraulic rod 148, the rotating pressure rod 146 will push the rotating push rod 151 to move. The movement of the rotating push rod 151 will push the scraping rod 152 to move. The movement of the scraping rod 152 will clean the surface of the filter screen 153, preventing impurities from adhering to the surface of the filter screen 153 and ensuring good collection of rainwater. When the rainwater in the water collection frame 149 reaches a certain height, the rainwater will drain through the drain port. When the precipitation of the external rain exceeds the drainage volume of the drain port, the storage volume of the rainwater in the water collection frame 149 will exceed the height of the drain port. Then, the weight inside the water collection frame 149 will press the sliding plate 154 to slide downward. The downward sliding of the sliding plate 154 will cause the water outlet to release the contact with the circular plate 155. Then, the limit of the drainage groove will be released, allowing the rainwater to drain through the drainage groove. The downward sliding of the sliding plate 154 will push the lower pressure rod 156 downward. The downward movement of the lower pressure rod 156 will push the circular ring 157 downward. The downward sliding of the circular ring 157 will push the vertical rod 1593 downward. The downward movement of the vertical rod 1593 will push the sliding block 1592 to slide in the direction of the limit block 1591. Then, the sliding block 1592 will push the limit block 1591 upward. The upward sliding of the limit block 1591 will release the contact with the fixed plate 159. Then, the limit block 1591 will disengage from the fixed plate 159, and the limit of the fixed plate 159 will be released. Then, the limit of the elastic support rod 158 will be released. Then, the elastic support rod 158 will be pushed by the second torsion spring to rotate away from the support column 1. When the elastic support rod 158 rotates away from the support column 1, the elastic support rod 158 will extend to support the ground, strengthening the support force for the support column 1. When the rainfall is too heavy on a rainy day, strong winds will accompany it. When the wind force is too strong, the support force of the support column 1 will be insufficient, causing the support column 1 to be blown and tilted to one side.
