Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic power generation, and more specifically, to a solar photovoltaic power generation device and method. Background Technology

[0002] With the development of science and technology, solar energy has been widely used. Solar energy is a new type of pollution-free energy. In the field of solar power generation, solar panels need to be installed on solar panel mounting frames so that the solar panels can generate electricity.

[0003] However, existing mounting brackets have limited functionality. Many solar panels are installed on both sides of roads, where there is excessive dust and debris. A lot of dust falls onto the solar panels, easily covering them and affecting their power generation efficiency, and may even further damage their function.

[0004] Chinese Patent No. 209330011U discloses a solar panel mounting bracket that facilitates the cleaning of snow and dust. The device is a solar panel mounting bracket body that is bolted to the ground.

[0005] However, this device suffers from poor mobility and a fixed angle for the solar panel mounting bracket, resulting in less than ideal power generation efficiency. In windy areas, this device cannot effectively secure the solar panels, leading to damage. The overall mobility of the solar panels is significantly reduced, and directional adjustments are difficult during use. Consequently, the solar panels often only receive sunlight for a limited time, resulting in low power generation efficiency.

[0006] Therefore, a solar photovoltaic power generation device and method are proposed. Summary of the Invention

[0007] In view of the problems existing in the prior art, the purpose of this invention is to provide a solar photovoltaic power generation device and method, which can realize the movable solar photovoltaic power generation device at any time, eliminate the installation process, prevent strong winds from damaging the solar photovoltaic power generation device, and also recycle dust on the solar panel to prevent dust from covering the solar panel and affecting the power generation efficiency of the solar panel, thereby improving the service life of the solar panel and reducing costs.

[0012] Furthermore, the humidification mechanism includes a water pump fixed to the bottom of the water tank; a water level sensor fixed to one side of the bottom of the water tank; four flexible hoses evenly connected to the lower surface of the water tank via pipes; one end of each of the four flexible hoses is connected to the water pump, and the other end extends into the interior of the third housing; a guide plate is fixed to the top of the third housing; a No. 3 spring is fixed to one side of the inner surface of the third housing; a mounting plate is fixed to one end of the No. 3 spring; a sponge is fixed to one side of the mounting plate, and one side of the sponge extends through the third housing to the outside.

[0013] Furthermore, the length of the four No. 4 connecting rods outside the mounting rod is greater than the sum of the thickness of the solar panel and the length of the No. 1 support rod, ensuring that the sponge fits tightly against the outer surface of the solar panel and serves a cleaning function.

[0014] Furthermore, the transmission ratio between gear number two and gear number three is 1:50, enabling the lifting mechanism to perform complete reciprocating motion.

[0018] A method for generating electricity using a solar photovoltaic power generation device includes the following steps:

[0019] S1: First, insert the fixing rod into the ground, and the extension mechanism will start working.

[0020] S2: The first connecting rod in the extension mechanism pushes the push block, causing the bottom of the solar panel to tilt outwards, and the first spring contracts, thus improving the power generation efficiency of the solar panel.

[0021] S3: When the first connecting rod pushes the push block, the top block at one end lifts the top head, causing lubricating oil to flow from the oil reservoir and lubricate the first gear.

[0022] S4: When the extension mechanism is working, it drives the lifting mechanism to start working. The lifting mechanism drives the cleaning mechanism on the fourth connecting rod to rise until it reaches the top.

[0023] S5: When the wind is strong, the lower end of the solar panel retracts inward when the extension mechanism retracts. The lifting mechanism drives the cleaning mechanism on the fourth connecting rod to descend. At this time, the sponge on the cleaning mechanism moves downward close to the outer surface of the solar panel, which plays a cleaning role.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] (1) When using this invention, you only need to find a well-lit place to insert the device into the ground and start using it immediately. This solves the problem of poor mobility. Because it can be inserted anywhere and can start working after stabilization, it greatly improves mobility.

[0026] (2) The cleaning mechanism set in this invention not only cleans the dust on the surface of the solar power panel, but also cleans the surface of the solar power panel, which further improves the power generation efficiency. Moreover, by setting a water storage tank and a rain sensor, the device can be added to water without manual labor, which reduces manual labor and improves practicality.

[0027] (3) The present invention is equipped with four solar power generation panels, which greatly improves the power generation efficiency. Moreover, the tilt angle of the solar power generation panels is controllable, which can greatly reduce the impact of strong winds on the solar power generation device, thus playing a role in wind protection.

Example

[0042] See Figures 1 to 11A solar photovoltaic power generation device includes a fixed rod 1, a control box 2 fixedly installed on the lower outer surface of the fixed rod 1; an extension mechanism 3 fixedly installed on the upper side of the fixed rod 1; an installation rod 15 fixedly installed on the upper surface of the extension mechanism 3; four first support rods 5 evenly fixedly installed on the lower outer surface of the installation rod 15; one end of each of the four first support rods 5 is rotatably connected to a solar power generation panel 4 via a hinge, and the first support rod 5 is located at the middle of one side of the outer surface of the solar power generation panel 4; four first springs 6 are evenly fixedly connected to the upper outer surface of the installation rod 15; one end of each of the four first springs 6 is fixedly connected to the upper outer surface of the solar power generation panel 4; the four solar power generation panels 4... Push blocks 8 are fixedly installed on the lower side of the outer surface of the device; the outer surface of the inclined side of the push block 8 is provided with toothed grooves 81, and the push block 8 is a triangular pyramid; a water storage tank 9 is fixedly installed at the upper end of the mounting rod 15; electric rotating shafts 10 are movably installed on both sides of the upper surface of the water storage tank 9; a cover 11 is fixedly installed at one end of the two electric rotating shafts 10; a fixing plate 14 is fixedly installed on one side of the outer surface of the water storage tank 9; a wind detector 13 is fixedly installed on the upper surface of the fixing plate 14; a rain sensor 7 is fixedly installed on the other side of the water storage tank 9; four first-order sliding grooves 12 are evenly arranged on the outer circular surface of the mounting rod 15; a cleaning mechanism for cleaning is provided inside the mounting rod 15; a self-lubricating mechanism is provided inside the push block 8.

[0043] As shown in the figure, the extension mechanism 3 includes a first housing 31 fixed to the upper end of the fixed rod 1; four second-order sliding grooves 38 are evenly arranged on the outer circular surface of the first housing 31; a motor 32 is fixedly installed at the inner bottom of the first housing 31; a turntable 33 is fixedly installed at the output end of the motor 32; four first-order connecting rods 34 are evenly fixed around the turntable 33, and the four first-order connecting rods 34 extend through the four second-order sliding grooves 38 to the outside of the first housing 31; a gear 37 is rotatably connected to one end of the four first-order connecting rods 34, and the first gear 37 and the tooth groove 81 are located on the same horizontal plane; a top block 36 is fixedly connected to one side of the upper surface of the four first-order connecting rods 34, and the top block 36 is located above the first gear 37; a second-order connecting rod 35 is fixedly installed at the middle position of the upper surface of the turntable 33, and one end of the second-order connecting rod 35 is movably installed in the first housing 31 and extends through the top of the first housing 31 to the inside of the mounting rod 15.

[0044] In response to the problems of the comparative patent, such as the inability to move freely, the limited time that the solar panels can receive sunlight, and the inability to effectively protect against damage caused by strong winds, the present invention solves this problem by using a fixing rod and an extension mechanism.

[0045] Using this invention, first insert the fixing rod 1 into the ground. After the device is fixed, start the extension mechanism 3 through the control box 2. When the extension mechanism 3 is working, the battery in the control box 2 provides power to start the motor 32. The motor 32 drives the turntable 33 to start rotating. The rotation of the turntable 33 drives the four first connecting rods 34 to rotate, and also drives the first gear 37 installed at one end of the first connecting rod 34 to rotate. The first gear 37 meshes with the tooth groove 81, pushing the push block 8, causing the bottom of the four solar panels 4 distributed around the mounting rod 15 to tilt outward. The stability of the solar panels 4 is ensured by the first support rod 5 fixed in the middle, and the first spring 6 also contracts due to the tilt of the solar panels 4 until the first gear 37 rotates to the end of the tooth groove 81, the solar panels 4 stop tilting, and the first spring 6 stops contracting. Then the wind detector 13 and the rain sensor 7 start to work. The wind detector 13 detects the wind speed by the rotation speed of the fan blades. When the wind detector 13 detects a strong wind, it sends a signal to the microcontroller. When the microcontroller receives the signal of strong wind, it controls the motor 32 to rotate. The rotation of the motor 32 causes no force to compress the first spring 6. At this time, the first spring 6 rebounds and restores the solar panel 4 to a vertical state.

[0046] When using this invention, you only need to find a well-lit location to insert the fixing rod 1 into the ground and start using it immediately. This solves the problem of poor mobility. Because it can be inserted anywhere and can start working after stabilization, it greatly improves mobility. The four solar panels 4 greatly improve the power generation efficiency, and the tilt angle of the solar panels 4 is controllable, which can greatly reduce the impact of strong winds on the solar power generation device, thus playing a role in wind protection.

[0047] like Figure 5As shown, the cleaning mechanism includes a lifting mechanism 95 fixedly connected inside the mounting rod 15; the lifting mechanism 95 includes a second gear 951 rotatably connected to a second connecting rod 35 inside the mounting rod 15; a third gear 952 is movably mounted on the upper surface of the first housing 31, and the third gear 952 is located on one side of the second gear 951 and meshes with it; a lead screw 953 is fixedly connected to the middle position of the upper surface of the third gear 952; an auxiliary rod 957 is fixedly connected to the upper surface of the first housing 31, and the auxiliary rod 957 is located on one side of the lead screw 953; a fixing block 956 is mounted on the top end of the lead screw 953 via a bearing; a lifting mechanism is slidably connected to the outer surface of the lead screw 953. A lowering platform 954; an auxiliary block 955 is fixedly connected to one side of the outer circular surface of the lifting platform 954, and one end of the auxiliary block 955 is sleeved on the outer circular surface of the auxiliary rod 957; four No. 4 connecting rods 93 are evenly fixedly connected around the outer circular surface of the lifting platform 954, and the four No. 4 connecting rods 93 extend through the No. 1 slide groove 12 to the outside of the mounting rod 15; one end of each of the four No. 4 connecting rods 93 is fixedly connected to a third housing 94; a guide plate 941 is fixedly connected to the inner top surface of the third housing 94; a sponge 942 is fixedly connected to one side of the outer surface of the third housing 94, and the sponge 942 penetrates the third housing 94 and extends into the interior; a humidification mechanism is provided between the third housing 94 and the water storage tank 9.

[0048] like Figure 3 , Figure 4 As shown, the humidification mechanism includes a water pump 92 fixed to the bottom surface of the water tank 9; a water level sensor 91 fixed to one side of the bottom of the water tank 9; four hoses 943 evenly connected to the lower surface of the water tank 9 through pipes; one end of each of the four hoses 943 is connected to the water pump 92, and the other end extends into the interior of the third housing 94; a guide plate 941 is fixed to the top of the interior of the third housing 94; a third spring 944 is fixed to one side of the inner surface of the third housing 94; a mounting plate 945 is fixed to one end of the third spring 944; a sponge 942 is fixed to one side of the mounting plate 945, and one side of the sponge 942 extends through the third housing 94 to the outside.

[0049] like Figure 2 As shown, the length of the four No. 4 connecting rods 93 outside the mounting rod 15 is greater than the sum of the thickness of the solar panel 4 and the length of the No. 1 support rod 5, ensuring that the sponge 942 is tightly attached to the outer surface of the solar panel 4 and plays a cleaning role.

[0050] like Figure 5 As shown, the transmission ratio of gear 951 to gear 952 is 1:50, which enables the lifting mechanism 95 to perform a complete reciprocating motion.

[0051] To address the issue of dust on the surface of solar panels affecting power generation efficiency, this invention solves the problem by incorporating a cleaning mechanism.

[0052] When the extension mechanism 3 starts working, the third housing 94 and the sponge 942 are at the bottom of the solar panel. As the motor 32 drives the turntable 33 to rotate, the lifting mechanism 95 also starts working. The rotation of the turntable 33 drives the second connecting rod 35, which is fixed to the turntable 33, to rotate. The second connecting rod 35 also drives the second gear 951, which is installed at one end of the second connecting rod 35, to rotate. The rotation of the second gear 951 drives the third gear 952, which meshes with the second gear 951, to rotate. The rotation of the third gear 952 drives the surface of the third gear 952 to rotate. When lead screw 953 rotates, lifting platform 954 begins to operate. Lifting platform 954 drives the four No. 4 connecting rods 93, which are fixed around its outer surface, to rise. The rising of the No. 4 connecting rods 93 simultaneously moves the third housing 94 upwards, and also moves the sponge 942 mounted on the third housing 94 upwards, cleaning the surface of the solar panel. When extension mechanism 3 is fully extended, the third housing 94 and sponge 942 move to the top of the solar panel. A spring is added inside the sponge to ensure it remains in close contact with the solar panel. When the solar panel 4 finishes operating, extension mechanism 3 retracts, and lifting platform 954 begins to descend. The descent of lifting platform 954 causes sponge 942 to descend as well. Because sponge 942 is in close contact with the outer surface of solar panel 4, its descent also cleans the outer surface of solar panel 4.

[0053] When it rains, the receiver of the rain sensor 7 receives rainwater and sends a signal to the microcontroller. Upon receiving the rain signal, the microcontroller controls the electric shaft 10 to rotate the cover 11 to collect rainwater, storing it in the water tank 82. When the water level detector 91 in the water tank 9 detects that the water level has reached a predetermined position, it sends a signal to the microcontroller. Upon receiving the signal, the microcontroller controls the electric shaft 10 to close the cover, stopping the collection of rainwater. If the predetermined water level has not been reached and the rain has stopped, the rain sensor 7 sends a signal indicating that the rain has stopped. The microcontroller receives this signal and controls the electric shaft 10 to close the cover, preventing water evaporation from the water tank 9. Whenever the motor 32 starts working, the water pump 92 in the water tank 9 sends water through a pipe into a hose 943, which then sends water into the third housing 94. The water in the third housing 94 flows through the guide plate 941 into the sponge 942, thus humidifying the water.

[0054] The cleaning mechanism of this invention not only cleans the dust on the surface of the solar panel 4, but also washes the surface of the solar panel 4, further improving the power generation efficiency. Moreover, by setting up a water storage tank 9 and a rain sensor 7, the device can be refilled with water without manual intervention, reducing labor and improving practicality.

[0055] like Figure 7 , Figure 8 , Figure 9 As shown, the self-lubricating mechanism includes an oil reservoir 82 fixedly connected to the upper surface of the tooth groove 81; a second housing 85 is fixedly connected to the inner bottom of the oil reservoir 82, and the lower surface of the second housing 85 penetrates the inner bottom of the oil reservoir 82 to the upper surface of the tooth groove 81; oil inlets 884 are provided on both sides of the outer surface of the second housing 85, and the oil inlets 884 are located above the inner bottom of the oil reservoir 82; an oil outlet 89 is provided on the lower surface of the second housing 85, and the oil outlet 89 penetrates the upper surface of the tooth groove 81 to the inner top of the tooth groove 81; the second housing 85... Two No. 2 springs 87 are fixedly connected to both sides of the inner bottom; one end of each of the two No. 2 springs 87 is fixedly connected to a No. 3 connecting rod 88; both ends of the No. 3 connecting rod 88 are equipped with sealing mechanisms; two No. 2 support rods 86 are provided on both sides of the lower surface of the No. 3 connecting rod 88, and the two No. 2 support rods 86 are respectively located on one side of the two No. 2 springs 87; a top rod 84 is fixedly connected to the middle of the lower surface of the No. 3 connecting rod 88, and one end of the top rod 84 extends through the oil outlet 89 into the interior of the tooth groove 81; one end of the top rod 84 is fixedly connected to a top head 83.

[0056] like Figure 8 As shown, both sides of the top block 36 are rounded, which makes it easier for the top block 36 to lift the top head 83 and reduce unnecessary wear.

[0057] like Figure 10 As shown, the sealing mechanism includes a first sealing ring 881 fixed to both ends of the third connecting rod 88; a fourth housing 882 fixed to both sides of the outer surface of the third connecting rod 88, and the fourth housing 882 is annular, covering both ends of the third connecting rod 88, with one side of the fourth housing 882 in close contact with the inner side of the third housing 94; a second sealing ring 883 fixed to the inner circular surface of the fourth housing 882, with one side of the second sealing ring 883 in close contact with the inner side of the third housing 94; the second sealing ring 883 serves as a second layer of protection, and the hollow interior of the fourth housing 882 is to retain excess lubricating oil and prevent waste.

[0058] To address the problem of wear between gear 37 and tooth groove 81, this invention solves the problem by setting a self-lubricating mechanism.

[0059] When the first connecting rod 34 drives the first gear 37 to start rotating, the top block 36 fixed to one end of the first connecting rod 34 also moves accordingly. When it reaches the middle position of the tooth groove 81, the top block 36 lifts the top head 83, which in turn drives the top rod 84 fixed to the top head 83 to lift the third connecting rod 88. The third connecting rod 88 is lifted and moves away from the support of the second support rod 86. The second spring 87 fixed to the third connecting rod 88 is then pulled. When the oil inlet 884 loses the seal of the first sealing ring 881 and the second sealing ring 884, the lubricating oil flows out from the oil inlet 884 and flows out from the oil outlet 89 onto the first gear 37, the first connecting rod 34 and the top block 36. When it passes through the middle position of the tooth groove 81, due to the lack of support from the top block 36, the third connecting rod 88 returns to its original position due to the retraction of the second spring 87, and the oil inlet 884 is sealed again by the first sealing ring 881 and the second sealing ring 884.

[0060] This invention incorporates a self-lubricating mechanism and a sealing mechanism, which solves the problem of manually lubricating the gears and tooth grooves, reduces manual operation steps, improves the service life of the gears and tooth grooves, and reduces unnecessary wear.

[0061] Instructions for use: (e.g.) Figure 11 As shown, it includes the following steps:

[0062] S1: First, insert the fixed rod 1 into the ground, and the extension mechanism 3 will start working.

[0063] S2: The first connecting rod 34 in the extension mechanism 3 pushes the push block 8, causing the bottom of the solar panel 4 to begin to tilt outward, and the first spring 6 to contract, thus improving the power generation efficiency of the solar panel 4.
