[0001] This application is a divisional application of application filed on September 17, 2025, with application number 202511323862.2 and invention title "A photovoltaic panel concentrating device and a concentrating method thereof". Technical Field

[0002] This invention relates to the field of photovoltaic power generation technology, specifically to a photovoltaic panel concentrator. Background Technology

[0003] Photovoltaic panels are an important component of solar photovoltaic power generation systems. They are a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of operation: stand-alone and grid-connected. Since photovoltaics is the phenomenon of potential difference generated between non-uniform semiconductors or semiconductor-metal combinations when exposed to light, photovoltaic technology has many advantages, such as having no mechanical moving parts, requiring no other "fuel" besides sunlight, and being able to work under both direct and oblique sunlight. To maximize the effectiveness of photovoltaic panels, a concentrating device is generally required. When concentrating photovoltaic panels, they are usually installed on the ground, and reflectors are placed around them to achieve the concentrating effect. However, since both the reflectors and the photovoltaic panels are fixed to the ground, and the reflectors can usually only receive sunlight from a specific direction and focus it onto a small area on the photovoltaic panel, it is difficult to capture and focus sunlight from multiple directions, thus affecting the concentrating effect and the power generation efficiency of the photovoltaic panels.

[0012] Furthermore, the end of the rubber shaft away from the sliding sleeve penetrates through the side wall of the arc-shaped plate and extends to the outside, and a flexible sphere is fixedly connected between the two rubber shafts; There are four sliding sleeves, which are arranged symmetrically in pairs. The rotating plates in each pair are symmetrically distributed with the center of the hollow frame as the center. The spiral grooves inside the two rotating plates are arranged in the same direction. A roller is provided on the side of the flexible sphere near the square groove. The roller is fixedly connected to the side wall of the rubber shaft and is in contact with the glass sphere.

[0013] Furthermore, a method for using a photovoltaic panel concentrator, the method comprising the following steps: S1: First, place the device in a suitable location. Then, connect the photovoltaic panel to the mounting frame with bolts. Next, connect the concentrator to the guide rod. After that, start the electric push rod. When the electric push rod is working, it will push the mounting frame with the photovoltaic panel to rise through the fixed shaft. S2: When the fixed shaft rises, it pushes the concentrator plate through the push plate and the top rod, causing the concentrator plate to expand outward and face the photovoltaic panel. Then, when sunlight shines on the concentrator plate, the sunlight can be concentrated onto the photovoltaic panel through the refraction of the concentrator plate, thus completing the light concentration effect.

[0014] The present invention has the following beneficial effects: 1. In this invention, when the photovoltaic panel is installed and the electric actuator is activated, the activation of the electric actuator will push the fixed shaft to rise. When the fixed shaft rises, the moving fixed shaft will push two swing plates to rotate via a push plate. When the swing plates rotate, they will cause the sliding block two to slide inside the semi-circular groove. When the sliding block two slides, it will drive the top rod, causing the top rod to change from an inclined state to a vertical state. When the top rod becomes vertical, the vertical top rod will push the concentrator plate, causing the concentrator plate to rotate on the guide rod. When the concentrator plate rotates... By rotating the four concentrators, they form a semicircle on top of the photovoltaic panel. As the four concentrators rotate, they drive the hollow frame to rise via a rotating plate. The rising hollow frame then causes the central glass sphere to rise synchronously and extend beyond the top of the concentrators. When the four concentrators form a semicircle around the glass sphere, the circular glass sphere can concentrate sunlight from different directions onto the photovoltaic panel, thereby enhancing the light intensity received by the photovoltaic panel and improving its power generation efficiency.

[0015] 2. In this invention, when the four focusing plates expand outward, the expanding hollow frame is driven to rise by a rotating plate. As the rotating plate rises, it rotates at the connection point of the hollow frame. This rotation pulls the sliding sleeve across the surface of the rotating shaft. Through the spiral groove inside the sliding sleeve, the rotating shaft rotates within the arc-shaped plate. This rotation drives the toothed plate to rotate, which meshes with the rubber shaft inside the square groove. The rotation of the toothed plate further drives the rubber shaft to rotate. Since the rotating shafts on both sides of the rubber shaft rotate in opposite directions, the rubber shaft twists, bends, and shortens as the toothed plate rotates. Furthermore, when the rubber shaft shortens, it pulls the flexible sphere, causing it to taut. Once taut, the flexible sphere adheres to the surface of the glass sphere. Then, when the rubber shaft rotates, it causes the flexible sphere to rotate on the surface of the glass sphere. Simultaneously, the rotation of the rubber shaft also drives the rollers on the surface of the glass sphere, pushing it to rotate. As the flexible sphere rotates, it removes dust from the surface, improving the cleanliness of the glass sphere. This reduces the obstruction and scattering of light by dust on the surface, significantly improving the light transmittance of the glass sphere. This allows more sunlight to pass through the glass sphere and be concentrated by the solar concentrator, reducing fluctuations in the concentrator effect caused by dust accumulation, thus making the light energy received by the photovoltaic panel more stable and uniform.

[0016] 3. In this invention, during the process of the light-concentrating plate forming a semi-circular state, the hollow frame is lifted by a rotating plate. When the rotating plate lifts the hollow frame, it causes the convex shaft to rotate at the connection point of the hollow frame. As the rotating plate drives the convex shaft to rotate, the rotating convex shaft rotates on the surface of the spiral shaft through a rectangular groove. When the convex shaft rotates, it generates a certain shearing force on the surface of the spiral shaft. Under the action of the shearing force, the spiral shaft drives the rubber rope to rotate. When the rubber rope is driven to rotate by the spiral shaft, the rotating rubber rope will become shorter and bend. When the rubber rope becomes shorter, it will pull the sliding cylinder to move inside the outer sleeve. When the sliding cylinder moves, it will push the second push plate to pull the crank to rotate. When the crank rotates, it will drive the fan at the bottom to rotate inside the air outlet pipe. At this time, The airflow generated by the fan enters the surface of the rotating sphere through the air outlet. As the glass sphere rotates, the rotating glass sphere drives the rotating sphere to rotate synchronously. As the rotating sphere rotates, it passes through multiple curved plates inside. Under the rotation of these curved plates, the air entering the surface of the rotating sphere through the air outlet is thrown onto the surface of the glass sphere through the circular holes on the surface of the rotating sphere. When the air hits the surface of the glass sphere, it blows off the dust cleaned by the flexible sphere, which helps to remove dust more thoroughly and further enhances its light transmittance. At the same time, it can also reduce the scratches on the surface of the glass sphere caused by dust floating on the surface of the glass sphere and being cleaned by the rotation of the flexible sphere, thereby maintaining the good optical performance of the glass sphere and extending its good light transmittance.

When the fixed shaft 202 rises, the moving fixed shaft 202 will push the two swing plates 304 to rotate through the push plate 305. When the swing plates 304 rotate, they will drive the sliding block 306 to slide inside the semi-circular groove 302. When the sliding block 306 is sliding, the sliding block 306 will drive the push rod 307, so that the push rod 307 changes from an inclined state to a vertical state.

[0024] The top of the main body 1 is provided with a fixing mechanism 4. The fixing mechanism 4 includes a rotating plate 401 rotatably connected to the side of the light-concentrating plate 102 near the top rod 307. A hollow frame 402 is rotatably connected to the outer surface of the four rotating plates 401. Several convex shafts 403 are fixedly connected to the side of the rotating plate 401 away from the light-concentrating plate 102. The rotating light-concentrating plate 102 will drive the hollow frame 402 to rise through the rotating plate 401. When the hollow frame 402 rises, it will drive the glass ball in the middle to rise synchronously and extend the glass ball out of the top of the light-concentrating plate 102.

[0025] The inner wall of the hollow frame 402 is open. The bottom of the rotating plate 401 has four rectangular slots 404. The rectangular slots 404 extend to the bottom inner wall of the hollow frame 402. Several limiting plates 405 are fixedly connected to the bottom inner wall of the hollow frame 402.

When the rotating plate 401 drives the hollow frame 402 to rise, the rotating plate 401 will rotate at the connection of the hollow frame 402.

[0026] An auxiliary mechanism 5 is provided inside the hollow frame 402. The auxiliary mechanism 5 includes a sliding cylinder 502 fixedly connected to the end of the rubber rope away from the spiral shaft 406. An outer sleeve 501 is slidably connected to the outer surface of the sliding cylinder 502. The outer sleeve 501 is fixedly connected to the bottom inner wall of the hollow frame 402.

When the rubber rope becomes shorter, it will pull the sliding cylinder 502 to move inside the outer sleeve 501. When the sliding cylinder 502 moves, it will pull the crank rod 504 to rotate through the push plate 503.

[0027] The top of the crank 504 extends through the straight groove and is rotatably connected to the top inner wall of the outer sleeve 501. The bottom of the crank 504 extends through the outer wall of the hollow frame 402 and extends to the outside. A fan is fixedly connected to the extended end of the crank 504.

When the crank 504 rotates, it will drive the fan at the bottom to rotate inside the exhaust pipe 505. At this time, the wind generated by the fan will enter the surface of the rotating ball 506 through the exhaust pipe 505. Then, when the glass ball rotates, the rotating glass ball will drive the rotating ball 506 to rotate synchronously.

[0028] A cleaning mechanism 6 is provided on the top of the hollow frame 402. The cleaning mechanism 6 includes a sliding sleeve 601 rotatably connected to the rotating plate 401 near the hollow frame 402. A spiral groove is formed inside the sliding sleeve 601, and a rotating shaft 602 is slidably connected inside the spiral groove. An arc-shaped plate 603 is rotatably connected to the outer surface of the rotating shaft 602. The arc-shaped plate 603 is fixedly connected to the top outer wall of the hollow frame 402. A toothed plate is fixedly connected to the end of the rotating shaft 602 away from the rotating plate 401. Two square openings are formed on the side wall of the arc-shaped plate 603. A rubber shaft 605 is rotatably connected inside the square groove 604. The outer surface of the rubber shaft 605 meshes with the toothed plate. The rotating plate 401 pulls the sliding sleeve 601 to move on the surface of the rotating shaft 602. Through the spiral groove inside the sliding sleeve 601, the rotating shaft 602 can be driven to rotate inside the arc plate 603 when the sliding sleeve 601 moves. When the rotating shaft 602 rotates, it will drive the toothed plate to rotate. When the toothed plate rotates, it will mesh with the rubber shaft 605 inside the square groove 604.

[0029] One end of the rubber shaft 605 away from the sliding sleeve 601 passes through the side wall of the arc plate 603 and extends to the outside.

The roller 607 contacts the glass sphere and, under the rotation of the toothed plate, can drive the rubber shaft 605 to rotate. Because the rotating shafts 602 on both sides of the rubber shaft 605 rotate... The direction of movement is opposite. When the rubber shaft 605 rotates on the toothed plate, the rubber shaft 605 will twist and bend, becoming shorter. When the rubber shaft 605 becomes shorter, it will pull the flexible ball 606, making the flexible ball 606 tense. After the flexible ball 606 becomes tense, it will adhere to the surface of the glass ball. Then, when the rubber shaft 605 rotates, it will drive the flexible ball 606 to rotate on the surface of the glass ball. At the same time, when the rubber shaft 605 rotates, it will also drive the roller 607 to push the ball to rotate on the surface of the glass ball.

[0030] A method for using a photovoltaic panel concentrator, comprising the following steps: S1: First, place the device in a suitable location, then connect the photovoltaic panel to the placement frame 203 with bolts, then connect the concentrator 102 to the guide rod 101, and then start the electric push rod 201. When the electric push rod 201 is working, it will push the placement frame 203 with the photovoltaic panel to rise through the fixed shaft 202. S2: When the fixed shaft 202 rises, it will push the concentrator 102 through the push plate 305 and the top rod 307, causing the concentrator 102 to expand outward and face the photovoltaic panel. Then, when sunlight shines on the concentrator 102, the sunlight can be concentrated on the photovoltaic panel through the refraction of the concentrator 102, thus completing the light concentration effect.

[0031] In use, first place the device in a suitable location, then connect the photovoltaic panel to the mounting frame 203 with bolts, and then connect the concentrator 102 to the guide rod 101. After completion, activate the electric actuator 201. When working, the electric actuator 201 will push the mounting frame 203 with the photovoltaic panel upward through the fixed shaft 202. When the fixed shaft 202 rises, it will push the concentrator 102 through the push plate 305 and the top rod 307, causing the concentrator 102 to expand outward and concentrate the light. The concentrator plate 102 faces the photovoltaic panel. When sunlight shines on the concentrator plate 102, the sunlight is concentrated onto the photovoltaic panel through refraction, achieving a concentrating effect. When the photovoltaic panel is installed and the electric actuator 201 is activated, the activation of the electric actuator 201 will push the fixed shaft 202 to rise. When the fixed shaft 202 rises, the moving fixed shaft 202 will push the two swing plates 304 to rotate through the push plate 305. When the swing plates 304 rotate, they will drive the sliding block 306 to rotate in a semi-circular motion. The inner surface of the circular groove 302 slides. When the sliding block 306 slides, it drives the top rod 307, causing it to change from an inclined state to a vertical state. When the top rod 307 becomes vertical, it pushes the concentrator 102, causing it to rotate on the guide rod 101. As the concentrator 102 rotates, the four concentrators 102 form a semi-circle on the top of the photovoltaic panel. When the four concentrators 102 rotate, the rotating concentrators 102 will drive the hollow frame 402 to rise through the rotating plate 401. When the hollow frame 402 rises, it will drive the glass sphere in the middle to rise synchronously and extend the glass sphere out of the top of the concentrator 102. When the four concentrators 102 form a semicircle and surround the glass sphere, the circular glass sphere can concentrate sunlight from different directions onto the photovoltaic panel, thereby enhancing the light intensity received by the photovoltaic panel and improving the power generation efficiency of the photovoltaic panel.

[0032] When the four focusing plates 102 expand outward, the expanding hollow frame 402 will rise via the rotating plate 401. As the rotating plate 401 rises, it will rotate at the connection point of the hollow frame 402. This rotation pulls the sliding sleeve 601 across the surface of the rotating shaft 602. Through the spiral groove inside the sliding sleeve 601, the movement of the sliding sleeve 601 will cause the rotating shaft 602 to rotate inside the arc-shaped plate 603. The rotation of the rotating shaft 602 will cause the toothed plate to rotate. The toothed plate will mesh with the rubber shaft 605 inside the square groove 604, and the rotation of the toothed plate will cause the rubber shaft 605 to rotate. Since the rotating shafts 602 on both sides of the rubber shaft 605 rotate in opposite directions, when the rubber shaft 605 rotates on the toothed plate... The rubber shaft 605 may twist and bend, shortening its length. When the rubber shaft 605 shortens, it pulls the flexible sphere 606, causing it to become taut. Once taut, the flexible sphere 606 adheres to the surface of the glass sphere. When the rubber shaft 605 rotates, it causes the flexible sphere 606 to rotate on the surface of the glass sphere. Simultaneously, the rotation of the rubber shaft 605 also drives the roller 607 to push the sphere to rotate on its surface. As the flexible sphere 606 rotates, it removes dust from the sphere's surface, improving its cleanliness. This reduces the obstruction and scattering of light by dust, significantly improving the light transmittance of the glass sphere. This allows more sunlight to pass through the glass sphere and be concentrated by the solar concentrator, reducing fluctuations in the concentrator effect caused by dust accumulation, thus making the solar energy received by the photovoltaic panel more stable and uniform.

[0033] When the focusing plate 102 forms a semi-circular shape, it drives the hollow frame 402 to rise via the rotating plate 401. As the rotating plate 401 drives the hollow frame 402 to rise, it causes the convex shaft 403 to rotate at the connection point of the hollow frame 402. When the rotating plate 401 drives the convex shaft 403 to rotate, the rotating convex shaft 403 rotates on the surface of the spiral shaft 406 via the rectangular groove 404. When the convex shaft 403 rotates, it generates a certain shearing force on the surface of the spiral shaft 406. Under the action of this shearing force, the spiral shaft 406 drives the rubber rope to rotate. As the rubber rope rotates, it shortens and bends. When the rubber rope shortens, it pulls the sliding cylinder 502 to move inside the outer sleeve 501. When the sliding cylinder 502 moves, it pulls the crank rod 504 to rotate via the pushing plate 503. The rotation of the crank rod 504 drives the bottom... The fan rotates inside the exhaust pipe 505. The airflow generated by the fan enters the surface of the rotating sphere 506 through the exhaust pipe 505. As the glass sphere rotates, it drives the rotating sphere 506 to rotate synchronously. The rotating sphere 506 passes through multiple curved plates inside. The rotation of these plates propels the air from the exhaust pipe 505 onto the surface of the rotating sphere 506 through the round holes on the surface of the sphere. When the air hits the surface of the glass sphere, it blows off the dust cleaned by the flexible sphere 606, helping to remove dust more thoroughly and further enhancing its light transmittance. At the same time, it reduces the likelihood of scratches on the surface of the glass sphere caused by dust floating on the surface and being cleaned by the rotation of the flexible sphere 606, thus maintaining the good optical performance of the glass sphere and extending its good light transmittance.
