Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a photovoltaic new energy self-cleaning power generation device. Background Art

[0002] Photovoltaic new energy power generation device is a device that uses solar energy to generate electricity. Its core principle is to directly convert solar energy into electrical energy through the photoelectric effect.

[0003] When sunlight shines on a solar panel, the photons in the light interact with the electrons in the silicon material, causing the electrons to gain energy and transition to become free electrons. These free electrons continue to gather on both sides of the PN junction, forming a potential difference. When the external circuit is turned on, the free electrons in the PN junction will flow and form a current. This is the electrical energy generated by the photovoltaic effect. The current generated by the solar panel is direct current, which needs to be converted into alternating current through an inverter so that it can be used by homes, businesses, etc. or injected into the power grid.

[0004] During the use of common photovoltaic panels, dust often adheres to the surface of the photovoltaic panels. The adhesion of this dust will reduce the photovoltaic panels' efficiency in absorbing solar energy. For this purpose, a rotating cleaning rod is usually designed to clean the surface of the photovoltaic panels. Common cleaning rods are fixed on mounting columns, and the mounting columns drive the cleaning rods to rotate so that the cleaning rods clean the surface of the photovoltaic panels. However, this cleaning method can only clean dust within a circular range with the mounting column as the center and the cleaning rod as the diameter, while photovoltaic panels are usually rectangular, which may lead to the problem that some photovoltaic panels cannot be cleaned. Therefore, it does not meet the existing needs. For this purpose, we propose a photovoltaic new energy self-cleaning power generation device. Summary of the invention

DETAILED DESCRIPTION

[0043] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0044] The present application provides a photovoltaic new energy self-cleaning power generation device, as shown below Figures 1 to 11 Elaborate in detail.

[0045] A photovoltaic new energy self-cleaning power generation device, comprising a support assembly, the support assembly comprising a support plate, a mounting plate is arranged on the support plate, a connecting frame is arranged between the mounting plate and the support plate, a photovoltaic panel is fixedly arranged on the mounting plate, a U-shaped plate is arranged along the peripheral side of the photovoltaic panel on the mounting plate, and a rotating device is arranged on one side of the opening of the U-shaped plate;

[0046] A sliding plate is provided on the end surface of the rotating device facing the photovoltaic panel, a first sliding groove is provided on the upper edge of the sliding plate parallel to the photovoltaic panel, a wiping component is provided on the sliding plate for sliding toward the photovoltaic panel, and a slider is provided on the wiping component for sliding connection with the first sliding groove in the direction of the first sliding groove;

[0047] A U-shaped track groove is provided on the inner wall of the U-shaped plate facing the photovoltaic panel. The wiping component is slidably connected to the U-shaped track groove, and the cross-section of the U-shaped track groove is configured as a T-shaped groove. The wiping component extends into the U-shaped groove and is connected to a guide roller in a T-shaped rotation. The guide roller is slidably connected to the U-shaped groove.

[0048] The present invention realizes cleaning of the photovoltaic panel by arranging a rotating device to drive the wiping component to rotate, and by arranging a U-shaped track groove and a guide roller in the U-shaped plate, the wiping component can move along the U-shaped track groove during the rotation process, that is, one end of the wiping component can move along the U-shaped track groove to wipe the entire surface of the photovoltaic panel clean, and there will be no situation where corners are left that cannot be cleaned.

[0049] In some embodiments, a triangular block is fixedly connected to the bottom of the support plate, and a timing motion motor is installed on one side of the triangular block. The design of the triangular block can make the photovoltaic panel be installed in an inclined state, and the photovoltaic panel with an inclined design can better absorb solar energy to improve the solar energy power generation efficiency of the device. The design of the timing motion motor can ensure that the side of the photovoltaic panel that absorbs solar energy can always face the sun, and the movement of the timing motion motor is a prior art. This solution does not describe the working principle and specific structure of the timing motion motor in detail.

[0050] In some embodiments, the rotating device includes a driving motor fixedly arranged on the support plate, the output end of the driving motor is arranged in a direction away from the support plate, and the output end of the driving motor is fixedly connected to a rotating seat, and a sliding sleeve around the outer wall of the rotating seat is provided with a fixed cylinder, and the fixed cylinder is fixedly connected to the outer wall of the driving motor, and the sliding plate is fixedly arranged at one end of the rotating seat away from the driving motor. The driving motor can adopt a servo motor, so as to provide more precise control. Driven by the driving motor, the rotating seat can drive the sliding plate to rotate, thereby driving the wiping assembly to rotate and completing the wiping and cleaning operation of the photovoltaic panel. The setting of the fixed cylinder can protect the rotating seat.

[0051] In some embodiments, a plurality of driving balls are embedded on the end surface of the fixed cylinder facing the sliding plate, and the driving balls are slidingly connected to the wiping assembly. The setting of the driving balls can change the sliding friction into rolling friction, thereby reducing the friction between the wiping assembly and the fixed cylinder, reducing the friction loss of the wiping assembly and the fixed cylinder, and can make the driving motor drive the wiping assembly to rotate faster at the same power, thereby improving the cleaning efficiency and reducing the power consumption.

[0052] In some embodiments, the wiping assembly includes a cleaning plate arranged parallel to the sliding plate, the slider is fixedly arranged on the side wall of the cleaning plate facing the sliding plate, a cleaning groove is opened on the side of the cleaning plate facing the photovoltaic panel, the cleaning groove is openly arranged on the side of the photovoltaic panel, and a flexible cleaning member is fixedly arranged on the side of the cleaning groove facing the photovoltaic panel;

[0053] Both ends of the cleaning plate are rotatably connected to the guide rollers.

[0054] The cleaning plate is connected to the sliding plate by sliding through the slider and the first slide groove. When the guide roller drives the cleaning plate to move along the U-shaped track groove, the cleaning plate will slide in the first slide groove, and due to the rotation of the driving motor, the sliding plate will rotate along with the guide roller, that is, when the guide roller moves to the corner of the U-shaped track groove, the sliding plate will drive one end of the cleaning plate to move to the corner of the photovoltaic panel, thereby completing the cleaning of the corners of the photovoltaic panel. The flexible cleaning member can be a sponge, cloth, felt, rubber or the like that can flexibly contact with the photovoltaic panel and clean the surface. Considering that there may be residual water on the photovoltaic module, the flexible cleaning member is preferably a sponge, which can absorb the residual water on the surface of the photovoltaic panel.

[0055] In some embodiments, an extrusion plate is provided in the cleaning tank along a direction perpendicular to the photovoltaic panel, a flexible cleaning member is provided between the extrusion plate and the cleaning tank, and a reset assembly is movably connected between the extrusion plate and the cleaning tank.

[0056] The squeezing plate is movably connected to the cleaning groove through a reset assembly, thereby realizing squeezing of the flexible cleaning member. When there is a lot of residual water on the photovoltaic panel, the flexible cleaning member will absorb the residual water. However, after absorbing water to a certain extent, the water in the flexible cleaning member will be saturated. The setting of the squeezing plate will produce a squeezing effect on the flexible cleaning member for a long time, so that the water in the flexible cleaning member is squeezed out, and due to the centrifugal force of the rotation process, the squeezed water will be quickly thrown out to the periphery of the photovoltaic panel, and the thrown out water will be absorbed by the flexible cleaning member again and thrown out again, thereby achieving the effect of cleaning excess water out of the surface of the photovoltaic panel.

[0057] And because the rotation process of the cleaning plate is not a normal circle, in most cases, a part of the cleaning work performed by the cleaning plate is a motion trajectory with a constantly changing radius but a constant center. At each moment during the rotation of the cleaning plate, the squeezing plate will stay in place due to inertia, and the cleaning plate will approach the squeezing plate driven by the rotating device. When the entire motion process is connected, there will be an effect of the squeezing plate and the cleaning plate squeezing the flexible cleaning member, thereby further squeezing out excess water in the flexible cleaning member, thereby ensuring that the flexible cleaning member can absorb water again when it is not squeezed or the squeezing force becomes smaller.

[0058] In some embodiments, an inclined groove is provided on the side of the extrusion groove facing away from the photovoltaic panel. By opening another inclined groove on the top of the extrusion groove, it can be ensured that when the extrusion plate is resisted and slides in the extrusion groove, it can move upward a distance in the direction perpendicular to the photovoltaic panel. Through this upward displacement, the extrusion plate and the cleaning plate can be prevented from being stuck by the driving ball, which can prevent the cleaning plate from being unable to rotate.

[0059] In some embodiments, the reset assembly includes a reset sleeve fixedly disposed on the inner wall of the cleaning tank, a reset pressure rod is slidably connected in the reset sleeve, a reset spring is provided at one end of the reset pressure rod facing the inner wall of the cleaning tank, a horizontal rod is provided at one end of the reset pressure rod facing the extrusion plate, and a second slide groove for the horizontal rod to slide is provided on the extrusion plate. The reset sleeve, the reset pressure rod and the reset spring can effectively connect the extrusion plate and the cleaning tank. After the distance between the extrusion plate and the cleaning tank becomes smaller, the reset of the reset spring can drive the extrusion plate to reset, so that the flexible cleaning member is no longer squeezed, so that the flexible cleaning member can absorb water to the maximum extent.

[0060] In some embodiments, a water tank is provided on the cleaning plate, and a swinging water spraying assembly connected to a water tank pipeline is provided on the extrusion plate; placing the water tank at a high position can effectively utilize the gravity of water, so that the swinging water spraying assembly can obtain sufficient water supply, and there is no need to set up a water supply component such as a water pump;

[0061] The swing water spray assembly includes an L-shaped opening groove vertically arranged on the side of the extrusion plate facing the photovoltaic panel, the L-shaped opening groove is perpendicular to the two ends of the photovoltaic panel and penetrates to the cleaning groove, the L-shaped opening groove is located in the groove space inside the extrusion plate and is slidably connected with a swing rod, a swing track groove is arranged at the position corresponding to the swing rod in the cleaning groove, the swing rod penetrates the L-shaped opening groove and is slidably connected with the swing track groove, and a plurality of swing grooves for the swing rod to be inserted are arranged in the swing track groove;

[0062] The L-shaped opening groove is located on the surface of the vertical extrusion plate, and a plurality of racks are slidably arranged in the groove space. The racks are fixedly connected to the rocking rod, and the tooth surface of the racks is arranged toward the photovoltaic module side, and a rocking gear is meshed under the racks. A nozzle is fixedly arranged at one end of the rocking gear toward the photovoltaic module, and a first pipeline is passed through between the rocking gear and the nozzle, and a limit plate for driving the gear to follow the movement of the extrusion plate is arranged on the side of the racks away from the extrusion plate;

[0063] A pipeline assembly for supplying water to the first pipeline is fixedly arranged on the cleaning plate, and the swing gear is rotatably connected to the pipeline assembly.

[0064] When one end of the cleaning plate moves along the U-shaped track groove driven by the guide roller, due to the centrifugal force, the extrusion plate and the swing rod will move toward one end of the U-shaped plate. At this time, due to the reduced spacing between the extrusion plate and the cleaning groove, the end of the swing rod in the extrusion plate will move toward the swing groove. When the swing rod is completely aligned with the swing groove, the swing rod will be inserted into the swing groove. At this time, the swing rod drives the rack to move, and the rack drives the swing gear to rotate, so that the nozzle follows the rotation, so that the nozzle spraying coverage area becomes larger. When any guide roller completes the movement in the U-shaped track groove, the other guide roller will enter the U-shaped track groove again and move. At this time, the swing rod will be inserted into the swing groove on the other side. At this time, the nozzle will follow the swing gear to swing in the opposite direction, thereby expanding the nozzle spraying area again.

[0065] When the cleaning plate stops rotating, the cleaning plate is no longer affected by centrifugal force. Due to the gravity of the nozzle itself, the swing gear will reset to the state where the nozzle is facing downward. At this time, the swing gear will drive the rack and the swing rod to reset. The swing rod is pulled out of the swing groove, and the extrusion plate can be reset under the action of the reset mechanism.

[0066] In one embodiment, the groove walls between adjacent swing grooves are chamfered to facilitate the swing rod to be inserted into or pulled out of the swing groove when following the movement of the extrusion plate.

[0067] In some embodiments, the pipeline assembly includes a plurality of folded tubes fixedly arranged on the side of the cleaning plate facing the photovoltaic assembly, and the folded tubes are arranged in one-to-one correspondence with the swing gears;

[0068] The free end of each folded tube is arranged toward one end of the photovoltaic panel, and a telescopic assembly is fixedly connected to the side of the folded tube free end facing the swing gear, and the telescopic assembly includes a telescopic sleeve fixedly connected to the free end of the folded tube, a telescopic inner rod fixedly connected to the swing gear, and a telescopic spring arranged between the telescopic inner rod and the telescopic sleeve, and the telescopic inner rod and the telescopic sleeve are rotatably and slidably connected;

[0069] A second pipe connected to the first pipe is arranged inside the telescopic inner rod, a water delivery port is opened on the telescopic sleeve, a bellows is arranged between the water delivery port and the second pipe, and the bellows is arranged in the internal space of the telescopic spring;

[0070] A third pipeline connected with the water delivery port is arranged inside the folded pipe, and a water delivery pipe is arranged between the third pipeline and the water tank.

[0071] When water needs to be delivered, the water in the water tank can enter the third pipe in the folded pipe along the water delivery pipe, and pass through the third pipe, the water delivery port, the bellows, the second pipe and the first pipe in sequence, and finally the water is sprayed out from the nozzle.

[0072] The arrangement of the telescopic inner rod, telescopic sleeve and telescopic spring can facilitate the water supply of the extrusion plate with the swing gear when it moves. The arrangement of the bellows will produce a corresponding change in distance when the spacing between the telescopic inner rod and the telescopic sleeve changes, thereby ensuring the stability of the water supply. And due to the fixed connection between the folding tube and the cleaning plate, the arrangement of the telescopic assembly can effectively provide support for the swing gear, so that the swing gear can obtain a stable support and rotation connection relationship when it moves with the extrusion plate under the action of the limit plate.

[0073] In some embodiments, an automatic water cut-off mechanism is provided at one end of the folded tube facing the photovoltaic assembly, and the automatic water cut-off mechanism includes a sliding bin arranged at a position of the folded tube facing the telescopic assembly, a connecting block is arranged in the sliding bin, and an L-shaped fourth pipe is arranged in the connecting block, one end of the fourth pipe can be connected to the third pipe, and the other end of the fourth pipe can be connected to the water inlet;

[0074] The sliding bin is provided with a passage position for the normal operation of the connecting block and a blocking position for blocking the normal operation of the connecting block. The passage position is located above the blocking position, and the passage position and the blocking position are connected.

[0075] A walking bin is provided at one end of the folded tube facing the photovoltaic panel, a driving block is provided in the walking bin and slides along the direction of the third pipeline, a ball bin is provided on the side of the driving block facing the photovoltaic panel, a walking ball is rotatably connected in the ball bin, a connecting rod is provided between the walking bin and the sliding bin, one end of the connecting rod is fixedly connected to the driving block, and the other end of the connecting rod is fixedly connected to the connecting block, an automatic circuit-breaking spring is provided on the outer sleeve of the connecting rod in the walking bin, and both ends of the automatic circuit-breaking spring are respectively fixedly connected to the driving block and the inner wall of the walking bin.

[0076] When the walking ball contacts the photovoltaic panel, the walking ball is lifted up, and the driving block moves upward in a direction perpendicular to the photovoltaic panel, thereby lifting up the connecting block in the sliding bin, so that the connecting block moves from the blocking position to the passage position in the sliding bin. At this time, the two ends of the L-shaped fourth pipe are connected to the third pipe and the water delivery port respectively. At this time, the water flow can be transported to the nozzle along the water delivery pipe, the third pipe, the fourth pipe, the water delivery port, the corrugated pipe, the second pipe, and the first pipe, and finally sprayed onto the photovoltaic panel;

[0077] When the walking ball is separated from the photovoltaic panel, it means that the corresponding part of the cleaning plate above the walking ball has been separated from the surface of the photovoltaic panel. At this time, the water spraying operation is no longer needed. At this time, the walking ball moves down, and the connecting block moves down from the access position to the disconnection position in the sliding bin, and the connecting block contacts the bottom wall of the sliding bin and no longer moves downward, ensuring that the driving block will not be separated from the walking bin. Since there are multiple racks and rocking gears, multiple folding pipes need to be set up, and an automatic water-cutting mechanism is set in each folding pipe, so that when the cleaning plate gradually separates from the photovoltaic panel, the operation effect of gradually cutting off the water of multiple folding pipes is achieved to achieve the purpose of water saving.

[0078] In some embodiments, in order to ensure that the connecting block can supply water normally, the height difference between the blocking positions and the passage positions is set to be the same as the thickness of the photovoltaic panel, thereby ensuring that after the connecting block rises from the blocking position to the passage position, the fourth pipe can face the water outlet, reducing the probability of flow reduction or other failures caused by misalignment of the pipe outlet.
