Description

Technical Field

[0001] The present invention belongs to the technical field of floating photovoltaic power generation, and specifically relates to a floating photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation is a technology that converts solar energy into electrical energy. It uses solar panels to absorb sunlight and converts solar radiant energy into electrical energy through the photovoltaic effect. However, the construction of large-scale photovoltaic power generation facilities requires a large amount of land resources, and is also restricted by problems such as heat dissipation, which makes it impossible to apply photovoltaic power generation well.

[0003] In order to solve the problems of land occupation and heat dissipation in photovoltaic power generation, the prior art has proposed floating photovoltaic power generation. By combining photovoltaic panels with buoys and placing the buoys on the surface of water bodies such as reservoirs, lakes, and seas, it can not only effectively reduce the land occupation area, but also improve the heat dissipation effect of the equipment and reduce the water evaporation of the water body itself.

[0004] In the existing floating photovoltaic power generation devices, generally, multiple buoys are placed on the water surface to form a buoy group, and then photovoltaic panels are installed on the buoys. However, the photovoltaic panels are fixed on the buoys, and their angles cannot change with the angle of the sun, resulting in the photovoltaic panels not being able to receive sunlight well, thus affecting the power generation efficiency of the photovoltaic panels.

[0005] Therefore, the present invention provides a floating photovoltaic power generation device. Summary of the Invention

First, the user sets the fixed anchor at the bottom of the water area to be built, and then lays the buoys on the water surface where the fixed anchor is provided. During the laying process, the buoys should also be arranged in a determinant pattern. Then, the user connects each buoy together through the docking component, so that a plurality of buoys form a whole. Subsequently, the fixed anchor at the bottom of the water is connected to the connecting component on the surface of the buoy through a steel cable to improve the wind resistance of the overall buoy. Then, the user comes to the end of a row of buoys, and then pushes the connecting rod in the chute, so that the docking column at the end of the connecting rod abuts against the end of the next connecting rod in the row, and the slot at the end of the docking column cooperates with the next connecting rod in the row, thereby connecting all the connecting rods in the whole row together through the docking column. Subsequently, the user installs the driving component at the end of each row of buoys, and then the driving component drives the rotating shaft to rotate, and through the connecting rods and docking columns connected end to end in the same row, it is realized that only one driving component drives the rotating shaft at the end to rotate, which can drive the photovoltaic panels in the whole row to rotate, so as to synchronously adjust the light-receiving angle of each row of photovoltaic panels, so that each photovoltaic panel can receive sufficient light, thereby improving the power generation efficiency of the photovoltaic panel.

[0008] Preferably, the driving component includes a servo motor, and the housing of the servo motor is connected to the support plate by bolts; a main gear is fixedly connected to the output shaft of the servo motor; a sub-gear is fixedly connected to the surface of the rotating shaft; the main gear meshes with the sub-gear; the servo motor drive is connected to an external control component; the control component is used to control the servo motor to rotate regularly; during operation, when the user needs to install the driving component, the user only needs to find the buoy at the end of each row of buoys, and then mesh the main gear at the output end of the servo motor with the sub-gear on the surface of the end rotating shaft, and then fixedly connect the servo motor to the support plate by bolts to complete the installation of the power source. The servo motor can then rotate at a fixed time and angle through the external control component, so that each photovoltaic panel can be adjusted to an appropriate angle facing the sun, thereby further improving the power generation efficiency of the photovoltaic panel.

[0009] Preferably, the support component includes two pairs of first struts and second struts; the support plate is connected to the first strut away from the docking column by bolts; the first strut and one second strut are paired in twos, and one ends of the first strut and the second strut are both rotatably connected to the top surface of the buoy; a receiving groove is formed on the side of the second strut close to the first strut, and the receiving groove is adapted to the first strut; a connecting block is provided at the end of the second strut away from the buoy, and the connecting block is connected to the second strut by bolts; the end of the connecting block away from the second strut is connected to the first strut by bolts; the rotating shaft is rotatably connected to the connecting block; during operation, before the embodiment of the present invention is laid on the water surface, that is, during the transportation process of the embodiment of the present invention, in order to facilitate loading and transportation, the bolts between the connecting block and the first strut and the second strut can be removed, and then the mounting plate can be removed from the surface of the first strut. Then, first rotate the first strut so that the first strut buckles towards the top surface of the buoy, and then buckle the second strut towards the first strut until the first strut is covered by the receiving groove, and then separate and store the connecting block, the rotating shaft and the photovoltaic panel from the buoy, thereby effectively reducing the volume of the embodiment of the present invention and facilitating the transportation of the embodiment of the present invention.

[0010] Preferably, on the surface of the connecting block close to the docking column and close to the docking column, there are two pairs of connecting grooves, and the two pairs of connecting grooves are evenly arranged around the rotating shaft; on the surface of the docking column close to the connecting block, there are two pairs of insertion rods fixedly connected; the insertion rods are located at the four corners of the connecting rod, and the insertion rods are adapted to the connecting grooves; during operation, when transporting the whole of the connecting block, the rotating shaft and the photovoltaic panel, the user needs to push the docking column towards the connecting block so that the insertion rods at the end of the docking column are inserted into the connecting grooves on the surface of the connecting block, thereby fixing the positions of the connecting rod, the docking column and the rotating shaft, so that the positions of each connecting rod, docking column and rotating shaft are the same, in order to facilitate the subsequent docking of the connecting rod with the end slot of the docking column, thereby reducing the difficulty for the user to assemble the embodiment of the present invention.

[0011] Preferably, the insertion rod is made of a magnet; a magnet sheet is fixedly connected to the bottom of the connecting groove; the magnet sheet and the insertion rod attract each other; during operation, when the insertion rod is inserted into the connecting groove, the insertion rod will be adsorbed by the magnet sheet at the bottom of the connecting groove, thereby fixing the docking column connected to the insertion rod, thereby preventing the insertion rod from falling out of the connecting groove due to vibration when transporting the embodiment of the present invention.

[0012] Preferably, the docking assembly includes a docking block; the docking block is arranged in a hollow structure and is filled with air; both ends of the docking block are fixedly connected to a pair of symmetrically arranged connecting seats; the connecting seat is provided with a mounting groove at one end away from the docking block; a docking plate is slidably connected in the mounting groove; springs are fixedly connected between the top and bottom surfaces of the docking plate and the groove wall of the mounting groove; connecting plates are fixedly connected to the corresponding positions of the docking plates around the buoy; the connecting plates are connected to the docking plates by bolts; the docking column and the connecting rod are connected by a universal shaft; during operation, when the user assembles the buoy and the photovoltaic panel, etc., and lays them on the water surface, the user It is also necessary to connect the buoys together through a docking block, that is, to connect the docking plate at the end of the docking block and the connecting plate on the surface of the two adjacent rows of buoys through bolts. After the buoys are connected into a whole through the docking block, when encountering windy and choppy weather, since the docking plate is connected to the connecting seat through a spring, the buoy can drive the docking plate to slide in the installation groove through the connecting plate, so that each buoy and the docking block can move relative to each other, thereby avoiding the docking plate or connecting plate used to connect the docking block and the buoy surface due to the rigid connection between the buoy surfaces in windy and choppy weather, thereby improving the wind and wave resistance of the embodiment of the present invention.

[0013] Preferably, the mounting groove is fixedly connected to a pair of waterproof membranes at the groove opening; the two waterproof membranes are respectively located on the top and bottom surfaces of the docking plate, and the waterproof membranes are fixedly connected to the surface of the connecting plate; the bottom surface inside the mounting groove is funnel-shaped; a drainage hole is provided at the center of the bottom surface inside the mounting groove; during operation, after the docking block is connected to the buoy, the waterproof membrane will close the groove opening of the mounting groove, thereby preventing a large amount of water vapor from gathering in the mounting groove, causing the spring in the mounting groove to rust and corrode, affecting the normal use of the embodiment of the present invention, and at the same time, condensed water caused by temperature difference and other reasons can also flow from the drainage hole at the bottom of the mounting groove to the outside of the connecting seat, thereby keeping the spring as dry as possible and reducing the probability of rust.

[0014] Preferably, a limiting rod is arranged in the liquid discharge pipe; a floating ball is fixedly connected to the bottom of the limiting rod; the diameter of the floating ball is larger than the diameter of the liquid discharge hole; one end of the docking plate close to the installation groove is concave; the limiting rod is slidably connected to the top surface inside the installation groove, and the limiting rod passes through the concave part of the docking plate and the middle part of the spring; during operation, in rainy or windy weather, the water surface will rise. Since the buoy is connected to the fixed anchor at the bottom of the water, the rising height of the buoy and the docking block connected to the buoy is limited. When the rising height of the buoy and the docking block reaches the upper limit and the water surface continues to rise, it will contact the floating ball, thereby pushing the floating ball and the limiting rod to rise, and then the floating ball blocks the liquid discharge hole, thus preventing excessive water accumulation in the installation groove. At the same time, in windy weather, when the water wave hits the floating ball, it can also push the floating ball to close the liquid discharge hole, thereby reducing the water entering the installation groove. In sunny weather, under the action of its own gravity, the floating ball will move away from the liquid discharge hole, enabling the accumulated water in the installation groove to be discharged.

[0015] Preferably, the connection assembly includes two connection rings; both of the two connection rings are rotatably connected to the surface of the buoy, and the two connection rings are symmetrical about the rotating shaft; a pair of symmetrically arranged fixed rings are fixedly connected to the surface of the connection ring; during operation, when the user needs to connect the buoy to the fixed anchor at the bottom of the water, the user can first connect the fixed ring at the top of the connection ring to the fixed anchor through a steel cable, and then the user rotates the connection ring to rotate the fixed ring connected to the fixed anchor below the water surface, and then throws the fixed anchor into the water, thus facilitating the user to connect the fixed anchor to the buoy and also facilitating the user to put the fixed anchor into the water.

[0016] Preferably, four uniformly arranged card slots are formed on one side surface of the connection ring; limiting blocks are rotatably connected to both sides of the buoy at the connection ring; during operation, when the user needs to rotate the connection ring, the user needs to rotate the limiting block so that the limiting block rotates out of the card slot. At this time, the limiting block no longer blocks the card slot, and then the user can rotate the connection ring. During transportation, in order to prevent the fixed ring from being pressed at the bottom and causing damage to the fixed ring, the user can rotate the connection ring so that the fixed rings at both ends of the connection ring are horizontally arranged, and then rotate the limiting block and insert it back into the card slot to fix the connection ring, thereby preventing the fixed ring from contacting the bottom of the buoy and causing the buoy to be squeezed.

[0017] The beneficial effects of the present invention are as follows: 1. For the water-based photovoltaic power generation device of the present invention, through a row of connecting rods and docking columns connected end to end, only one driving component is used to drive the rotating shaft at the end to rotate, which can drive the rotation of the entire row of photovoltaic panels, thereby synchronously adjusting the light-facing angles of each row of photovoltaic panels, enabling each photovoltaic panel to receive sufficient sunlight, and thus improving the power generation efficiency of the photovoltaic panels.

[0018] 2. The water-based photovoltaic power generation device described in the present invention can effectively reduce the volume of the embodiment of the present invention through the folding and storage of the first support rod, the second support rod, and the receiving groove, thereby facilitating the transportation of the embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 3As shown in the figure, a kind of water-based photovoltaic power generation device described in the embodiment of the present invention includes a plurality of buoys 1, and the buoys 1 are arranged in an annular structure; a docking component is arranged between the plurality of buoys 1; the docking component is used to connect each buoy 1 together; a pair of connection components are installed on the surface of the buoy 1; the connection components are used to connect the fixed anchors at the bottom of the water; a support component is installed on the top of the buoy 1; a photovoltaic panel 101 is arranged on the top of the support component; the bottom surface of the photovoltaic panel 101 is fixedly connected with a rotating shaft 2; the rotating shaft 2 is rotatably connected with the support component; a chute 3 is opened at one end of the rotating shaft 2; the chute 3 penetrates through the rotating shaft 2, and the notch of the chute 3 is rectangular; a connecting rod 4 is slidably connected in the chute 3; a docking column 5 is installed at one end of the connecting rod 4; a slot 6 is opened at the end of the docking column 5 away from the connecting rod 4, and the slot 6 is adapted to the connecting rod 4; a support plate 7 is arranged on the side of the support component away from the docking column 5; a driving component is installed on one of the support plates 7; the driving component is used to drive the rotating shaft 2 to rotate; during operation, when building a photovoltaic power generation facility in large water areas such as reservoirs, lakes and the sea surface, the embodiment of the present invention can be adopted. First, the user sets the fixed anchors at the bottom of the water area to be built, and then lays the buoys 1 on the water surface where the fixed anchors are provided. During the laying process, the buoys 1 should also be arranged in a determinant pattern. Then, the user connects each buoy 1 together through the docking component, so that a plurality of buoys 1 form a whole. Subsequently, the fixed anchors at the bottom of the water are connected with the connection components on the surface of the buoys 1 through steel cables to improve the wind resistance of the whole buoy 1. Then, the user comes to the end of a row of buoys 1 and pushes the connecting rod 4 in the chute 3, so that the docking column 5 at the end of the connecting rod 4 abuts against the end of the next connecting rod 4 in this row, and the slot 6 at the end of the docking column 5 is matched with the next connecting rod 4 in this row, thereby connecting the whole row of connecting rods 4 together through the docking column 5. Subsequently, the user installs the driving component at the end of each row of buoys 1, and then the driving component drives the rotating shaft 2 to rotate. Through the connecting rods 4 and docking columns 5 connected end to end in the same row, it is realized that only one driving component drives the rotating shaft 2 at the end to rotate, and then the photovoltaic panels 101 in the whole row can be driven to rotate, so as to synchronously adjust the light-facing angles of each row of photovoltaic panels 101, so that each photovoltaic panel 101 can receive sufficient light, thereby improving the power generation efficiency of the photovoltaic panel 101.

[0023] As Figures 1 to 2As shown in the figure, the drive assembly includes a servo motor 8, and the housing of the servo motor 8 is connected to the support plate 7 by bolts; a main gear 9 is fixedly connected to the output shaft of the servo motor 8; a secondary gear 10 is fixedly connected to the surface of the rotating shaft 2; the main gear 9 meshes with the secondary gear 10; the servo motor 8 is driven and connected to an external control assembly; the control assembly is used to control the servo motor 8 to rotate regularly; during operation, when the user needs to install the drive assembly, the user only needs to find the buoy 1 at the end of each row of buoys 1, and then mesh the main gear 9 at the output end of the servo motor 8 with the secondary gear 10 on the surface of the end rotating shaft 2, and then fixedly connect the servo motor 8 to the support plate 7 by bolts, then the installation of the power source can be completed. The servo motor 8 can then rotate at a fixed time and angle through the external control assembly, so that each photovoltaic panel 101 can be adjusted to an appropriate angle facing the sun, thereby further improving the power generation efficiency of the photovoltaic panel 101.

[0024] As Figures 1 to 4 shown, the support assembly includes two pairs of first support rods 11 and second support rods 12; the support plate 7 is connected to the first support rod 11 away from the docking column 5 by bolts; the first support rod 11 and a second support rod 12 are arranged in pairs, and one end of the first support rod 11 and the second support rod 12 are both rotatable on the top surface of the buoy 1; a receiving groove 13 is formed on the side of the second support rod 12 close to the first support rod 11, and the receiving groove 13 is adapted to the first support rod 11; a connecting block 14 is provided at the end of the second support rod 12 away from the buoy 1, and the connecting block 14 is connected to the second support rod 12 by bolts; the end of the connecting block 14 away from the second support rod 12 is connected to the first support rod 11 by bolts; the rotating shaft 2 is rotatably connected to the connecting block 14; during operation, before the embodiment of the present invention is laid on the water surface, that is, during the transportation process of the embodiment of the present invention, in order to facilitate loading and transportation, the bolts between the connecting block 14 and the first support rod 11 and the second support rod 12 can be removed, and then the mounting plate can be removed from the surface of the first support rod 11. Then, first rotate the first support rod 11 so that the first support rod 11 buckles towards the top surface of the buoy 1, and then buckle the second support rod 12 towards the first support rod 11 until the first support rod 11 is covered by the receiving groove 13, and then separate and store the connecting block 14, the rotating shaft 2 and the photovoltaic panel 101 from the buoy 1, thereby effectively reducing the volume of the embodiment of the present invention, and thus facilitating the transportation of the embodiment of the present invention.

[0025] As Figure 1 and Figure 5As shown in the figure, on the surface of the connection block 14 close to the docking column 5, there are two pairs of connection grooves 15 on the side close to the docking column 5, and the two pairs of connection grooves 15 are evenly arranged around the rotating shaft 2; on the side surface of the docking column 5 close to the connection block 14, there are two pairs of insertion rods 16 fixedly connected; the insertion rods 16 are located at the four corners of the connecting rod 4, and the insertion rods 16 are adapted to the connection grooves 15; during operation, when transporting the whole of the connection block 14, the rotating shaft 2 and the photovoltaic panel 101, the user needs to push the docking column 5 towards the connection block 14, so that the insertion rods 16 at the end of the docking column 5 are inserted into the connection grooves 15 on the surface of the connection block 14, thereby fixing the positions of the connecting rod 4, the docking column 5 and the rotating shaft 2, so that the positions of each connecting rod 4, docking column 5 and rotating shaft 2 are the same, to facilitate the subsequent docking of the connecting rod 4 with the end face slot 6 of the docking column 5, and thus reduce the difficulty for the user to assemble the embodiment of the present invention.

[0026] As Figure 8 shown, the insertion rod 16 is made of magnet; a magnet sheet 17 is fixedly connected to the bottom of the connection groove 15; the magnet sheet 17 and the insertion rod 16 attract each other; during operation, when the insertion rod 16 is inserted into the connection groove 15, the insertion rod 16 will adsorb with the magnet sheet 17 at the bottom of the connection groove 15, thereby fixing the docking column 5 connected to the insertion rod 16, and thus preventing the insertion rod 16 from falling out of the connection groove 15 due to vibration during the transportation of the embodiment of the present invention.

[0027] As Figure 1 and Figure 6As shown, the docking component includes a docking block 18; the docking block 18 is provided with a hollow structure and is filled with air inside; both ends of the docking block 18 are fixedly connected with a pair of symmetrically arranged connecting seats 19; an installation groove 20 is opened at one end of the connecting seat 19 away from the docking block 18; a docking plate 121 is slidably connected in the installation groove 20; springs 21 are fixedly connected between the top surface and the bottom surface of the docking plate 121 and the groove walls of the installation groove 20; connecting plates 22 are fixedly connected at the corresponding positions around the buoy 1 and the docking plate 121; the connecting plates 22 and the docking plate 121 are connected by bolts; the docking column 5 and the connecting rod 4 are connected by a universal joint; during operation, when the user assembles the buoy 1 and the photovoltaic panel 101, etc., and lays them on the water surface, the user also needs to connect the buoys 1 together through the docking block 18, that is, connect the docking plate 121 at the end of the docking block 18 with the connecting plates 22 on the surfaces of two adjacent rows of buoys 1 by bolts. After the buoys 1 are connected into a whole through the docking block 18, in case of windy and wavy weather, since the docking plate 121 is connected with the connecting seat 19 through the spring 21, the buoy 1 can drive the docking plate 121 to slide in the installation groove 20 through the connecting plate 22, so that relative movement can occur between each buoy 1 and the docking block 18, thereby avoiding the breakage of the docking plate 121 or the connecting plate 22 used for connecting between the docking block 18 and the surface of the buoy 1 due to rigid connection between the surfaces of each buoy 1, and further improving the anti-wind and wave ability of the embodiment of the present invention.

[0028] As Figures 6 to 7 shown, a pair of waterproof membranes 23 are fixedly connected at the notch of the installation groove 20; the two waterproof membranes 23 are respectively located on the top surface and the bottom surface of the docking plate 121, and the waterproof membranes 23 are fixedly connected with the surface of the connecting plate 22; the bottom surface inside the installation groove 20 is in a funnel shape; a liquid discharge hole 24 is opened at the center of the bottom surface inside the installation groove 20; during operation, after the docking block 18 is connected with the buoy 1, the waterproof membranes 23 will seal the notch of the installation groove 20, thereby preventing a large amount of water vapor from gathering in the installation groove 20, resulting in the rust and corrosion of the spring 21 inside the installation groove 20 and affecting the normal use of the embodiment of the present invention. At the same time, the condensed water caused by temperature difference and other reasons can also flow from the liquid discharge hole 24 at the bottom of the installation groove 20 to the outside of the connecting seat 19, thereby keeping the spring 21 dry as much as possible and reducing the probability of its rust.

[0029] As Figure 7As shown, a limiting rod 25 is arranged inside the liquid discharge pipe; a floating ball 26 is fixedly connected to the bottom of the limiting rod 25; the diameter of the floating ball 26 is larger than the diameter of the liquid discharge hole 24; one end of the docking plate 121 close to the installation groove 20 is concave; the limiting rod 25 is slidably connected to the top surface inside the installation groove 20, and the limiting rod 25 passes through the concave part of the docking plate 121 and the middle of the spring 21; during operation, in rainy or windy weather, the water surface will rise. Since the buoy 1 is connected to the fixed anchor at the bottom of the water, the rising height of the buoy 1 and the docking block 18 connected to the buoy 1 is limited. When the rising height of the buoy 1 and the docking block 18 reaches the upper limit and the water surface continues to rise, it will contact the floating ball 26, thereby pushing the floating ball 26 and the limiting rod 25 to rise, and then the floating ball 26 blocks the liquid discharge hole 24, thus avoiding excessive water accumulation in the installation groove 20. At the same time, in windy weather, when the water wave impacts the floating ball 26, it can also push the floating ball 26 to close the liquid discharge hole 24, thereby reducing the water entering the installation groove 20. In sunny weather, under the action of its own gravity, the floating ball 26 will move away from the liquid discharge hole 24, enabling the accumulated water in the installation groove 20 to be discharged.

[0030] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the connection assembly includes two connection rings 27; both of the two connection rings 27 are rotatably connected to the surface of the buoy 1, and the two connection rings 27 are symmetric about the rotating shaft 2; a pair of symmetrically arranged fixed rings 28 are fixedly connected to the surface of the connection ring 27; during operation, when the user needs to connect the buoy 1 to the fixed anchor at the bottom of the water, the user can first connect the fixed ring 28 at the top of the connection ring 27 to the fixed anchor through a steel cable, and then the user rotates the connection ring 27 to rotate the fixed ring 28 connected to the fixed anchor below the water surface, and then throws the fixed anchor into the water, so as to facilitate the user to connect the fixed anchor to the buoy 1 and also facilitate the user to throw the fixed anchor.

[0031] As Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, four evenly arranged card slots 29 are provided on one surface of the connecting ring 27; limiting blocks 30 are rotatably connected to both sides of the buoy 1 and at the connecting ring 27; during operation, when the user needs to rotate the connecting ring 27, the user needs to rotate the limiting block 30 so that the limiting block 30 rotates out of the card slot 29. At this time, the limiting block 30 no longer blocks the card slot 29, and at this time the user can rotate the connecting ring 27. During transportation, in order to prevent the fixing ring 28 from being pressed to the bottom and causing damage to the fixing ring 28, the user can rotate the connecting ring 27 so that the fixing rings 28 at both ends of the connecting ring 27 are horizontally arranged, and then rotate the limiting block 30 to reinsert it into the card slot 29 to fix the connecting ring 27, thereby preventing the fixing ring 28 from contacting the bottom of the buoy 1 and causing the buoy 1 to be squeezed.

[0032] During operation, when building a photovoltaic power generation facility in large water areas such as reservoirs, lakes and seas, the embodiments of the present invention can be adopted. First, the user sets fixed anchors at the bottom of the water area where the facility needs to be built, and then lays the buoys 1 on the water surface where the fixed anchors are provided. During the laying process, the buoys 1 should be arranged in a row. Then, the user connects the buoys 1 together through the docking components so that multiple buoys 1 form a whole. Subsequently, the fixed anchors at the bottom are connected to the connection components on the surface of the buoys 1 through steel cables to improve the wind resistance of the overall buoys 1. Then, the user comes to the end of a row of buoys 1 and pushes the connecting rod 4 in the chute 3 so that the docking column 5 at the end of the connecting rod 4 abuts against the end of the next connecting rod 4 in the row, and the slot 6 at the end of the docking column 5 is matched with the next connecting rod 4 in the row. In this way, the connecting rods 4 in the whole row are connected together through the docking column 5. Subsequently, the user installs the driving component at the end of each row of buoys 1. Then, the driving component drives the rotation shaft 2 to rotate, and through the connecting rods 4 and docking columns 5 connected end to end in the same row, it is possible to drive the rotation of the rotation shaft 2 at the end with only one driving component, and then drive the rotation of the photovoltaic panels 101 in the whole row, so as to synchronously adjust the light-facing angles of each row of photovoltaic panels 101, so that each photovoltaic panel 101 can receive sufficient light, thereby improving the power generation efficiency of the photovoltaic panels 101.

[0033] When the user needs to install the driving component, the user only needs to find the buoy 1 at the end of each row of buoys 1, and then mesh the main gear 9 at the output end of the servo motor 8 with the sub-gear 10 on the surface of the end rotation shaft 2. Then, the servo motor 8 is fixedly connected to the support plate 7 through bolts, and the installation of the power source can be completed. The servo motor 8 can rotate at a fixed time and angle through an external control component, so that each photovoltaic panel 101 can be adjusted to an appropriate angle facing the sun at each time, thereby further improving the power generation efficiency of the photovoltaic panels 101.

[0034] Before the embodiment of the present invention is laid on the water surface, that is, during the transportation process of the embodiment of the present invention, in order to facilitate loading and transportation, the bolts between the connecting block 14, the first support rod 11 and the second support rod 12 can be removed, and then the mounting plate can be removed from the surface of the first support rod 11. Then, first rotate the first support rod 11 to make the first support rod 11 buckle towards the top surface of the buoy 1, and then buckle the second support rod 12 towards the first support rod 11 until the first support rod 11 is covered by the receiving groove 13. Then, store the connecting block 14, the rotating shaft 2 and the photovoltaic panel 101 separately from the buoy 1. Thus, the volume of the embodiment of the present invention can be effectively reduced, and further the transportation of the embodiment of the present invention is facilitated.

[0035] When transporting the whole of the connecting block 14, the rotating shaft 2 and the photovoltaic panel 101, the user needs to push the docking column 5 towards the connecting block 14 so that the insertion rod 16 at the end of the docking column 5 is inserted into the connecting groove 15 on the surface of the connecting block 14, thereby fixing the positions of the connecting rod 4, the docking column 5 and the rotating shaft 2, so that the positions of each connecting rod 4, docking column 5 and rotating shaft 2 are the same, in order to facilitate the subsequent docking of the connecting rod 4 with the end face slot 6 of the docking column 5, and further reduce the difficulty for the user to assemble the embodiment of the present invention.

[0036] When the insertion rod 16 is inserted into the connecting groove 15, the insertion rod 16 will adsorb with the magnet sheet 17 at the bottom of the connecting groove 15, thereby fixing the docking column 5 connected to the insertion rod 16, and further avoiding the insertion rod 16 from disengaging from the connecting groove 15 due to vibration during the transportation of the embodiment of the present invention.

[0037] After the user assembles the buoy 1 and the photovoltaic panel 101, etc. and lays them on the water surface, the user also needs to connect each buoy 1 together through the docking block 18, that is, connect the docking plate 121 at the end of the docking block 18 with the connecting plate 22 on the surface of two adjacent rows of buoys 1 through bolts. After the buoys 1 are connected into a whole through the docking block 18, in case of windy and wavey weather, since the docking plate 121 is connected to the connecting seat 19 through the spring 21, the buoy 1 can drive the docking plate 121 to slide in the installation groove 20 through the connecting plate 22, so that relative movement can occur between each buoy 1 and the docking block 18, thereby avoiding the breakage of the docking plate 121 or the connecting plate 22 used for connecting between the docking block 18 and the surface of the buoy 1 due to rigid connection between the surfaces of each buoy 1 in windy and wavey weather, and further improving the anti-wind and wave ability of the embodiment of the present invention.

[0038] After the docking block 18 is connected to the buoy 1, the waterproof film 23 will seal the notch of the installation groove 20, thereby preventing a large amount of water vapor from gathering in the installation groove 20, which may cause the spring 21 in the installation groove 20 to rust and corrode, affecting the normal use of the embodiment of the present invention. At the same time, the condensed water caused by reasons such as temperature difference can also flow from the liquid discharge hole 24 at the bottom of the installation groove 20 to the outside of the connection seat 19, thereby keeping the spring 21 dry as much as possible and reducing the probability of its rust.

[0039] In rainy or windy weather, the water surface will rise. Since the buoy 1 is connected to the fixed anchor at the bottom of the water, the rising height of the buoy 1 and the docking block 18 connected to the buoy 1 is limited. When the rising height of the buoy 1 and the docking block 18 reaches the upper limit and the water surface continues to rise, it will contact the floating ball 26, thereby pushing the floating ball 26 and the limiting rod 25 to rise, and then the floating ball 26 will block the liquid discharge hole 24, thereby preventing too much water from accumulating in the installation groove 20. At the same time, in windy weather, when the water wave hits the floating ball 26, it can also push the floating ball 26 to block the liquid discharge hole 24, thereby reducing the water entering the installation groove 20. In sunny weather, under the action of its own gravity, the floating ball 26 will move away from the liquid discharge hole 24, so that the accumulated water in the installation groove 20 can be discharged.

[0040] When the user needs to connect the buoy 1 to the fixed anchor at the bottom of the water, the user can first connect the fixed ring 28 at the top of the connecting ring 27 to the fixed anchor through a steel cable, and then the user rotates the connecting ring 27 to make the fixed ring 28 connected to the fixed anchor rotate below the water surface, and then throws the fixed anchor into the water, which is convenient for the user to connect the fixed anchor to the buoy 1 and also convenient for the user to place the fixed anchor.

[0041] When the user needs to rotate the connecting ring 27, the user needs to rotate the limiting block 30 so that the limiting block 30 rotates out of the card slot 29. At this time, the limiting block 30 no longer blocks the card slot 29, and at this time the user can rotate the connecting ring 27. During transportation, in order to prevent the fixed ring 28 from being pressed at the bottom and causing damage to the fixed ring 28, the user can rotate the connecting ring 27 so that the fixed rings 28 at both ends of the connecting ring 27 are horizontally arranged, and then rotate the limiting block 30 and insert it back into the card slot 29 to fix the connecting ring 27, thereby preventing the fixed ring 28 from contacting the bottom of the buoy 1 and causing the buoy 1 to be squeezed.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
