Description

Technical Field

[0001] The invention relates to the technical field of solar energy, and more specifically to a full-angle automatic light-chasing solar water heating system. Background Art

[0002] The solar water heating system uses solar collectors to collect solar heat. The system can provide hot water for production and life. It is the most economically valuable, technologically mature and commercialized application product in the development of solar thermal energy applications. It is the core part of the solar power generation system and the most important part of the solar power generation system.

[0003] The Chinese patent with publication number CN117928112B discloses a light-chasing type solar thermal collector. Through the design of the light-chasing mechanism, the first light sensor can sense the elevation angle of the solar collector receiving solar energy, and the second light sensor can sense the azimuth angle of the solar energy. The first motor works, and the push-pull plate pushes and pulls the solar collector, prompting the solar collector to adjust the elevation angle with the round rod as the axis. The first electric push rod works to prompt the rack to drive the gear to rotate, and the solar collector adjusts the azimuth angle with the connecting rod as the axis. In this way, the adjustment of the azimuth adjustment angle can be flexibly switched, and the light-chasing step can be completed quickly with high sensitivity. The Chinese patent with publication number CN112556207A discloses a solar panel light-chasing adjustment device, including a base, a revolving plate, a central shaft, a pitch transmission assembly and a solar collector. The turntable is installed on the base and forms a one-way rotating pair with the base. The central rotating shaft and the turntable form a one-way rotating pair. The direction in which the turntable is allowed to rotate relative to the base is opposite to the direction in which the turntable is allowed to rotate relative to the central rotating shaft. The central rotating shaft is driven to rotate by a driving motor. One side edge of the solar collector plate is hinged to the turntable. The solar collector plate is connected to the central rotating shaft through a pitch transmission assembly. The pitch transmission assembly converts the one-way rotation of the central rotating shaft relative to the turntable into a reciprocating flipping motion of the solar collector plate. The forward and reverse rotation of the driving motor is used to adjust the azimuth and elevation of the solar collector plate, so that the solar collector plate always faces the sun.

[0004] However, the inventors found that in actual use, when the solar panels track sunlight, the dust or impurities accumulated on the surface for a long time affect the entry of sunlight, reducing the thermal efficiency of solar energy conversion. Ordinary cleaning devices cannot achieve the effect of thorough dust removal. At the same time, due to the unreasonable setting of the tracking sensor, the sensitivity of the solar panels in tracking sunlight is relatively low. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and provide a full-angle automatic light-chasing solar water heating system, which controls the solar panels to automatically track the sun through light-chasing components so that the solar panels are always vertically aligned with the sun, and achieves the effect of automatic cleaning of the solar panels through cleaning components and blowing components to prevent excessive dust from affecting the thermal efficiency of the solar panels.

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.

[0022] It is worth mentioning that Figure 2 As shown, the mounting assembly 3 also includes a rotating seat 32 rotatably arranged on the base 1, a support rod 33 fixedly arranged on the rotating seat 32, a fixed shaft 34 fixedly arranged on the support rod 33, and a rotating frame 35 fixedly arranged on the mounting frame 31. The mounting frame 31 and the rotating frame 35 are both rotatably matched with the fixed shaft 34. When in use, the mounting frame 31 and the rotating frame 35 rotate around the fixed shaft 34 to adjust the elevation angle of the solar panel 4.

[0023] In addition, if Figure 2 As shown, the adjustment component 2 includes a first motor 21 fixedly arranged in the base 1, an active tooth 22 fixedly arranged on the first motor 21, a passive tooth 23 fixedly arranged on a rotating seat 32, and an electric push rod 24 fixedly arranged on a support rod 33. The output shaft of the electric push rod 24 is hingedly connected to the mounting frame 31. When in use, the first motor 21 is started to drive the active tooth 22 and the passive tooth 23 to rotate, thereby adjusting the azimuth angle of the solar panel 4.

[0024] It should be further explained that if Figures 2 to 6As shown, the light-chasing component 5 also includes a fixing seat 53 fixed on the base 1, a microcontroller arranged in the fixing seat 53, the reference rod 51 and the photosensor 52 are both arranged on the fixing seat 53, the microcontroller is electrically connected to the first motor 21 and the electric push rod 24, and the photosensor 52 is electrically connected to the microcontroller, wherein the microcontroller is connected to an external power supply and energized. When in use, the sun shines on the reference rod 51, and when the shadow of the reference rod 51 is projected on the photosensor 52, the light intensity felt by the photosensor is inconsistent, and an adjustment signal is transmitted to the microcontroller. The microcontroller drives the first motor 21 and the electric push rod 24 to enable the solar panel 4 to be vertically aligned with the sunlight, thereby increasing the exposure time of the solar panel 4. The shadow projected by the reference rod 51 is projected on the photosensor 52 with corresponding changes following the movement trajectory of the sun. Therefore, the microcontroller reads the data of the photosensor 52, determines the position of the sun through comparative analysis, and makes the adjustment of the solar panel 4 more precise.

[0025] It should be emphasized that if Figure 3 As shown, the driving assembly 6 includes a fixed rod 61 fixedly arranged on one side of the mounting frame 31, a slide rail 62 fixedly arranged on the other side of the mounting frame 31, a sliding frame 63 slidably arranged on the slide rail 62, a screw rod 64 rotatably arranged on the fixed rod 61, a moving block 65 slidably arranged on the screw rod 64, and a second motor 66 fixedly arranged on the fixed rod 61. The output shaft of the second motor 66 is connected to the screw rod 64. When in use, the second motor 66 can drive the screw rod 64 to rotate forward and reverse, and the screw rod 64 drives the sliding frame 63 and the moving block 65 to slide.

[0026] It is worth mentioning that Figures 5 to 7 As shown, the cleaning assembly 7 includes a water storage tank 71 fixedly arranged on the base 1, a water pipe 72 rotatably arranged between the moving block 65 and the sliding frame 63, a channel 73 opened in the sliding frame 63, a plurality of water spray holes 74 opened on the water pipe 72, a hose 75 fixedly arranged between the sliding frame 63 and the water storage tank 71, a water pump 76 fixedly arranged on the water storage tank 71, a gear 77 fixedly arranged on both sides of the water pipe 72, a rack 78 fixedly arranged on both sides of the mounting frame 31, and the hose 75. The gear 77 is connected to the channel 73 and the water pipe 72, and the gear 77 is meshed with the rack 78. When in use, the second motor 66 drives the moving block 65 and the sliding frame 63 to move, which can drive the water pipe 72 to slide on the surface of the solar panel 4. At the same time, when the gear 77 passes through the rack 78, the gear 77 and the water pipe 72 rotate. The water pump 76 transfers the water in the water tank 71 to the water pipe 72 through the hose 75 and the channel 73, and sprays it from the water spray hole 74, so as to flush the solar panel 4. In addition, the water tank 71 can also collect rainwater on rainy days to save water resources. When the water pipe 72 rotates, it drives the water spray hole 74 to rotate, and the water rotates and sprays, which has the effect of preventing floating dust.

[0027] Further, such as Figure 8 As shown, the blowing assembly 8 includes a guide cylinder 81 rotatably arranged on the sliding frame 63, a slide groove 82 opened on the guide cylinder 81, a cylinder body 83 fixedly arranged on the sliding frame 63, a piston 84 slidably arranged in the cylinder body 83, a rectangular rod 85 fixedly arranged on the piston 84, an air pipe 86 fixedly arranged between the sliding frame 63 and the moving block 65, and an air hole 87 obliquely arranged on the air pipe 86. The bottom of the rectangular rod 85 is set to be spherical and matched with the slide groove 82. The guide cylinder 81 is connected to the water pipe 72 through a belt. When in use, when the water pipe 72 rotates, the guide cylinder 81 is driven to rotate through the belt, so that the rectangular rod 85 drives the piston 84 to slide back and forth in the cylinder body 83, and the gas in the cylinder body 83 is injected into the air pipe 86 and blown out from the air hole 87, so that the water and dust on the solar panel 4 are blown off, and the solar panel 4 is automatically cleaned.

[0028] In addition, if Figure 8 As shown, the slide groove 82 is configured as a wave-shaped groove structure, thereby driving the piston 84 to slide back and forth to achieve a linkage effect.

[0029] Among them, Figure 7 As shown, a dirt detector 9 is provided on the solar panel 4 and is electrically connected to the second motor 66. The dirt detector 9 drives the second motor 66 to work after detection, thereby achieving an automatic cleaning effect.

[0030] Working process: When the sun shines on the reference rod 51 and the shadow on the reference rod 51 is projected on the light sensor 52, the light intensity felt by the light sensor is inconsistent, and the adjustment signal is transmitted to the microcontroller. The microcontroller drives the first motor 21 and the electric push rod 24 to make the solar panel 4 vertically align with the sunlight, thereby increasing the exposure time of the solar panel 4. When the dirt detector 9 detects, it drives the second motor 66 to work, driving the screw rod 64 to rotate forward and reverse, and the screw rod 64 drives the sliding frame 63 and the moving block 65 to slide, which can drive the water pipe 72 to move in the sun. The surface of the solar panel 4 slides, and when the gear 77 passes through the rack 78, the gear 77 and the water pipe 72 rotate, and the water pump 76 transmits the water in the water tank 71 to the water pipe 72 through the hose 75 and the channel 73, and sprays it out from the water spray hole 74. At the same time, the belt drives the guide cylinder 81 to rotate, so that the rectangular rod 85 drives the piston 84 to slide back and forth in the cylinder 83, and the gas in the cylinder 83 is injected into the air pipe 86 and blown out from the air hole 87, so that the water and dust on the solar panel 4 are blown off, and the solar panel 4 is automatically cleaned.
