DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, the present invention provides a photovoltaic power generation device with high power generation efficiency, including a base 1, the top outer wall of the base 1 is fixedly connected to a fixing plate 4, and the top outer wall of the base 1 is provided with a driving mechanism 2; the driving mechanism 2 includes a motor 201, the output shaft of the motor 201 is fixedly connected to a bevel gear A209, the outer wall of the bevel gear A209 is provided with a driving gear 208 through an adjusting mechanism 6, the top outer wall of the base 1 is slidably connected to a rack 207, the top outer wall of the base 1 is slidably connected to a moving rod 211, the outer wall of the moving rod 211 is hinged to a connecting rod 206, the top outer wall of the base 1 is hinged to a photovoltaic panel 5, the outer wall of the bevel gear A209 is meshed with a bevel gear B210, the inner wall of the fixing plate 4 is rotatably connected to a sprocket A202, the outer wall of the sprocket A202 is transmission-connected to a sprocket B204 through a chain 203, the outer wall of the sprocket B204 is fixedly connected to a threaded rod 205, and the outer wall of the threaded rod 205 is provided with a cleaning mechanism 3.

[0029] The above scheme is adopted: the photovoltaic panel 5 is the main body of the photovoltaic power generation device, which can be fixed on the ground through the base 1, absorbs sunlight and converts it into light energy to generate electricity, which is a prior art; through the driving mechanism 2, under the setting of a set of motors 201, not only the angle of the photovoltaic panel 5 can be adjusted to make the photovoltaic panel 5 receive solar energy comprehensively according to the change of the sun's position to improve the efficiency of photovoltaic power generation, but also the cleaning mechanism 3 can be driven to make the soft brush 303 in the cleaning mechanism 3 clean the surface of the photovoltaic panel 5 back and forth to reduce dust, leaves, dirt and other impurities on the surface of the photovoltaic panel 5, so that sunlight can better penetrate the glass cover to irradiate the battery cell, thereby improving the power generation efficiency, and reducing the demand for the number of motors 201 and reducing the cost; through the setting of the adjusting mechanism 6, the object driven by the output shaft of the motor 201 can be changed , the cleaning mechanism 3 can be kept fixed when adjusting the angle of the photovoltaic panel 5, and the cleaning mechanism 3 can also be driven to clean and keep the angle of the photovoltaic panel 5 fixed at the same time; the adjustment mechanism 6 can connect the bevel gear A209 with the driving gear 208, or disconnect the connection between the two, and a group of adjustment mechanisms 6 are also arranged between the bevel gear B210 and the sprocket A202, and the two can also be connected or disconnected through the adjustment mechanism 6; a control program can be written in the microcontroller connected to the motor 201, the instructions from the communication module are parsed, and the operation of the motor 201 is controlled according to the instructions. When the instruction to start the motor 201 is received, the program can apply a suitable voltage and current to the motor 201 through the interface of the driver to make it start to rotate, so that the operator can remotely control the motor 201.

[0030] like Figures 2 to 4 As shown, the motor 201 is fixedly connected to the top outer wall of the base 1, the driving gear 208 is meshed with the rack 207, and the driving gear 208 is rotatably connected to the top outer wall of the base 1; the connecting rod 206 is hinged to the bottom outer wall of the photovoltaic panel 5, the sprocket B204 is rotatably connected to the inner wall of the fixed plate 4, and the threaded rod 205 is rotatably connected to the inner wall of the fixed plate 4.

[0031] The above scheme is adopted: when the bevel gear A209 is connected to the driving gear 208 through the adjustment mechanism 6, and the adjustment mechanism 6 between the bevel gear B210 and the sprocket A202 is in the disconnected state, the output shaft of the motor 201 can drive the bevel gear A209 to rotate, and drive the driving gear 208 to rotate synchronously through the adjustment mechanism 6. When the driving gear 208 rotates, the tooth block continuously squeezes the tooth block on the rack 207. Since the rack 207 is slidably connected to the outer wall of the base 1, the rack 207 can be moved horizontally and squeeze the connecting rod 206. The two sets of connecting rods 206 are moved between The rod 211 is connected so that the connecting rod 206 moves with the rack 207 at the same time. Since the other end of the connecting rod 206 is hinged to the outer wall of the photovoltaic panel 5, the photovoltaic panel 5 is hinged on the base 1, so that it will flip when the connecting rod 206 moves, and drive the photovoltaic panel 5 to flip along the connection between it and the base 1, and support it through the connecting rod 206 to adjust the angle of the photovoltaic panel 5 to adapt to different positions of the sun; when the bevel gear A209 rotates, it will drive the bevel gear B210 to rotate synchronously, but because the adjustment mechanism 6 at one end of the bevel gear B210 is in a disconnected state, it will not drive the sprocket A202 to rotate.

[0032] like Figures 2 to 4 As shown, when the adjustment mechanism 6 between the bevel gear A209 and the driving gear 208 is disconnected, and the adjustment mechanism 6 between the bevel gear B210 and the sprocket A202 is connected, the motor 201 is started, and the output shaft of the motor 201 drives the bevel gear A209 to rotate, and drives the bevel gear B210 to rotate synchronously, but at this time the bevel gear A209 cannot drive the driving gear 208 to rotate, and the bevel gear B210 can drive the sprocket A202 to rotate through the adjustment mechanism 6, and drive the chain 203 to rotate. The sprocket B204 rotates, and there is an existing transmission mechanism between the sprocket A202, the chain 203 and the sprocket B204. When the sprocket B204 rotates, it will drive the threaded rod 205 to rotate synchronously. The threaded rod 205 can make the cleaning mechanism 3 move repeatedly to clean the surface of the photovoltaic panel 5; when the cleaning mechanism 3 needs to be used, the photovoltaic panel 5 needs to be adjusted to a horizontal state with the base 1 through the motor 201, so that the soft brush 303 in the cleaning mechanism 3 can clean the surface of the photovoltaic panel 5.

[0033] like Figure 4 and Figure 5As shown, the adjustment mechanism 6 includes a rotating shaft 601, the outer wall of the rotating shaft 601 is slidably connected to a slider 602, the outer wall of the slider 602 is provided with a slot 603, the inner wall of the slider 602 is clamped with an insertion rod 606, the inner wall of the insertion rod 606 is elastically connected to a clamping block 609 through a connecting spring 608, the outer wall of the insertion rod 606 is fixedly connected to a stopper 605, the outer wall of the insertion rod 606 is rotatably connected to a rotating rod 604, and the inner wall of the rotating rod 604 is provided with a sliding slot 607; the rotating shaft 601 is fixedly connected to the outer wall of the bevel gear A209, and the rotating rod 604 is fixedly connected to the outer wall of the driving gear 208; the blocking block 605 contacts the inner wall of the sliding groove 607, and the clamping block 609 is clamped with the clamping groove 603; one end of the connecting spring 608 is fixedly connected to the outer wall of the clamping block 609, and the other end of the connecting spring 608 is fixedly connected to the inner wall of the insertion rod 606, and the outer wall of the clamping block 609 is slidably connected to the inner wall of the insertion rod 606.

[0034] The above scheme is adopted: in the two groups of adjustment mechanisms 6, the rotating shaft 601 is respectively connected to the bevel gear A209 and the bevel gear B210, and the rotating rod 604 is respectively connected to the driving gear 208 and the sprocket A202. The rotating shaft 601 and the rotating rod 604 are two parts, and there is no contact between the two. However, the slider 602 on the outer wall of the rotating shaft 601 can be moved laterally, so that the groove 603 on the slider 602 is engaged with the block 609, and the two are connected, so that when the rotating shaft 601 rotates, the rotating rod 604 can be driven to rotate synchronously through the slider 602; the insertion rod 606 can rotate at a small angle inside the rotating rod 604, and the block 605 will contact the inner walls on both sides of the slide groove 607 when it rotates, so as to limit its rotation angle; when it is necessary to connect the rotating shaft 601 and the rotating rod 604, the block 609 in the insertion rod 606 can be pressed to move it to the insertion rod Inside 606, the connecting spring 608 is squeezed, and the slider 602 is moved to the position corresponding to the slot 603 and the block 609. The block 609 is ejected and engaged with the slot 603 by the elastic force of the connecting spring 608, and the connection is completed; when the connection is released, the block 609 is pressed to break contact with the slot 603, and the slider 602 can be moved to separate the two; because at each connection, the position of the rotating shaft 601 may not necessarily be exactly corresponding to the slot 603 and the block 609, the connection can be completed by rotating the plug rod 606 at a small angle to rotate the block 609 to the position corresponding to the slot 603; and the small angle rotation of the plug rod 606 will not affect the overall rotation between the rotating shaft 601 and the rotating rod 604, so it can be flexibly adjusted, and the setting of the motor 201 can be reduced, thereby reducing costs.

[0035] like Figure 6As shown, the cleaning mechanism 3 includes a moving block 301, the inner wall of the moving block 301 is elastically connected to a protrusion 306 through a reset spring 305, the outer wall of the protrusion 306 is fixedly connected to a short rod 307, the inner wall of the moving block 301 is slidably connected to a trapezoidal block 308, the top outer wall of the trapezoidal block 308 is fixedly connected to a pressing block 309, the outer wall of the moving block 301 is rotatably connected to a soft brush 303, the inner wall of the fixed plate 4 is slidably connected to a sliding block 302, and the inner wall of the sliding block 302 is provided with a groove 304.

[0036] The above scheme is adopted: the moving block 301 can move synchronously with the sliding block 302 to drive the soft brush 303 to clean the surface of the photovoltaic panel 5. The sliding block 302 is threadedly connected to the threaded rod 205. When the threaded rod 205 rotates, the sliding block 302 will be driven to move. Since the sliding block 302 is slidably connected to the inner wall of the fixed plate 4, it can only move laterally. Therefore, through the forward and reverse rotation of the threaded rod 205, the sliding block 302 and the moving block 301 are driven to move synchronously back and forth laterally, thereby scraping off impurities on the surface of the photovoltaic panel 5, avoiding blocking of sunlight, and improving the efficiency of photovoltaic power generation.

[0037] like Figure 6 As shown, the moving block 301 contacts the outer wall of the sliding block 302, the sliding block 302 is threadedly connected to the threaded rod 205, and the short rod 307 is slidably connected to the outer wall of the trapezoidal block 308; one end of the return spring 305 is fixedly connected to the outer wall of the protrusion 306, and the other end of the return spring 305 is fixedly connected to the inner wall of the moving block 301, the outer wall of the protrusion 306 is slidably connected to the inner wall of the moving block 301, and the protrusion 306 is snap-fitted into the groove 304.

[0038] The above scheme is adopted: the elastic force of the return spring 305 can drive the protrusion 306 to remain in the state of popping out, and the protrusion 306 can be engaged with the groove 304, so that the moving block 301 is fixed between the two sets of sliding blocks 302. In this state, the protrusion 306 drives the short rod 307 to keep it in contact with the long end side wall of the bottom end of the trapezoidal block 308. When the pressing block 309 is pressed downward, the trapezoidal block 308 can be driven to move downward synchronously. Since the short rod 307 can only move horizontally in the inner wall of the moving block 301, the short rod 307 can be moved along the inclined surface to the top short side of the trapezoidal block 308 , and drives the protrusion 306 to move synchronously into the inner wall of the moving block 301 and disengage from the groove 304, so that the limit of the moving block 301 can be released and it can be removed to clean the soft brush 303; during installation, the pressing block 309 can also be pressed downward, and the moving block 301 can be placed between the two sets of sliding blocks 302, so that the position of the protrusion 306 corresponds to the position of the groove 304, and the pressing block 309 is released. Under the elastic force of the return spring 305, the protrusion 306 pops out and engages with the groove 304, and the fixing of the moving block 301 is completed, which is convenient and quick to install, saving time and effort.

[0039] The working principle and use process of the present invention:

[0040] The photovoltaic panel 5 absorbs solar energy and converts it into electricity. Due to the different positions of the sun throughout the day, the angle of the photovoltaic panel 5 can be adjusted to face the sun, thereby absorbing solar energy more comprehensively to improve the power generation efficiency. In normal use, the adjustment mechanism 6 between the bevel gear A209 and the active gear 208 is in a connected state, while the adjustment mechanism 6 between the bevel gear B210 and the sprocket A202 is in a disconnected state. When adjustment is required, the operator can remotely start the motor 201, and the output shaft of the motor 201 rotates to drive the bevel gear A209 to rotate, and the active gear 208 is driven to rotate synchronously through the adjustment mechanism 6. Its tooth block continuously squeezes the tooth block on the rack 207, so that the rack 207 moves laterally, and squeezes the connecting rod 206, so that one end of the connecting rod 206 moves with the rack 207, and the other end will flip when moving, and drive the photovoltaic panel 5 to flip along the connection between it and the base 1, and support is provided by the connecting rod 206 to achieve the adjustment of the angle of the photovoltaic panel 5 to adapt to different positions of the sun, thereby better improving the power generation efficiency.

[0041] After long-term use, a large amount of dust, dirt and other impurities will adhere to the surface of the photovoltaic panel 5, blocking the sunlight and affecting the power generation efficiency. At this time, the operator can first adjust the photovoltaic panel 5 to a level with the base 1 through the motor 201, and then press the block 609 in the outer wall adjustment mechanism 6 of the bevel gear B210 to move it to the inside of the plug rod 606, squeeze the connecting spring 608, move the slider 602 to the position of the slot 603 and the block 609 to correspond closely, and then rotate the plug rod 606 at a small angle to make the block 609 and the slot 603 completely correspond. The block 609 is ejected and engaged with the slot 603 by the elastic force of the connecting spring 608, and the bevel gear B210 and the sprocket A202 can be connected; then press the block 609 in the outer wall adjustment mechanism 6 of the bevel gear A209 to disengage it from the slot 603, and move the slider 602 to disengage it from the plug rod 606, so that the connection between the bevel gear A209 and the driving gear 208 can be released.

[0042] At this time, start the motor 201, which can drive the bevel gear B210 to rotate through the bevel gear A209, and drive the sprocket A202 to rotate through the adjusting mechanism 6, and drive the sprocket B204 and the threaded rod 205 to rotate through the chain 203, and drive the sliding block 302 to move laterally in the inner wall of the fixed plate 4, so that the cleaning mechanism 3 can move synchronously, and the soft brush 303 contacts the surface of the photovoltaic panel 5 to scrape and clean it, thereby reducing the obstruction of surface impurities to sunlight and improving the power generation efficiency; after cleaning, the above-mentioned operation of adjusting the adjusting mechanism 6 can be repeated, so that the adjusting mechanism 6 outside the bevel gear B210 is disconnected, and the bevel gear A209 is connected to the driving gear 208, so that the photovoltaic panel 5 can be driven to adjust the angle again through the motor 201, and the cleaning and adjustment can be completed by only one set of motors 201, which reduces the cost.

[0043] When the soft brush 303 has been used for a long time and needs to be cleaned or replaced, the pressing blocks 309 on both sides can be pressed to drive the trapezoidal block 308 to move downward synchronously, and the short rod 307 moves along the inclined surface of the trapezoidal block 308 to the short side of the top end, and drives the protrusion 306 to move synchronously into the inner wall of the moving block 301, and the protrusion 306 is disengaged from the groove 304, and the limit of the moving block 301 is released, and the cleaning mechanism 3 can be removed as a whole to clean the soft brush 303; and when the cleaning mechanism 3 needs to be installed as a whole, the pressing block 309 can also be pressed, and the moving block 301 can be placed between the two sets of sliding blocks 302, so that the position of the protrusion 306 corresponds to the position of the groove 304, and the pressing block 309 is released. Under the elastic force of the reset spring 305, the protrusion 306 pops out and engages with the groove 304, completing the fixation of the moving block 301, and the operation is relatively convenient and quick.
