Description

[0002] The floating photovoltaic power generation system is an innovative renewable energy technology that is mainly installed on lakes, reservoirs and other water bodies. This technology generates electricity by installing photovoltaic panels on the water surface, which not only does not occupy valuable land resources, but also reduces the evaporation of water bodies. At the same time, the cooling effect of the water surface can reduce the operating temperature of the photovoltaic panels, thus helping to improve the efficiency of photovoltaic panels. In addition, this system can also reduce the growth of algae in the water body, which helps to improve water quality.

[0003] After the floating photovoltaic power generation equipment is placed on the water surface for a long time, parasites are easily attached to the floating body, which increases the weight of the floating body. The attachment of parasites will also shorten the life of the floating body and make it more prone to damage. Therefore, the floating body needs to be cleaned regularly, but the parasites are usually below the water surface, so manual cleaning is very inefficient. If an electric cleaning device is placed alone, the overall cost will increase significantly. Therefore, a power generation equipment that can efficiently clean parasites and is low in cost is needed. Summary of the invention

DETAILED DESCRIPTION

[0023] 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.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Embodiment 1: This embodiment provides a water surface floating photovoltaic power generation device, specifically, Figure 1-Figure 3 As shown, it includes multiple floating components 1, on which power generation components 3 are installed, and adjacent floating components 1 are connected together by connecting components 2. The floating component 1 includes a pontoon, on which a fixing ring 103 is installed, and a gear ring 104 is rotatably connected to the fixing ring 103, and a rotating frame 105 is installed on the gear ring 104, and a scraper 108 is installed on the rotating frame 105. The scraper 108 is used to clean the parasites on the side and bottom of the pontoon.

[0026] A plurality of floating components 1 are distributed in an array, and the adjacent floating components 1 in front, behind, left and right are connected via connecting components 2. The number of floating components 1 is set according to the specific scenario, so as to form a complete power generation equipment group.

[0027] like Figure 6 , Figure 8 The connecting assembly 2 shown includes a first ball pair unit 205 and a second ball pair unit 206. The first ball pair unit 205 is ball-connected to the second ball pair unit 206. A group of extrusion parts are respectively connected to the first ball pair unit 205 and the second ball pair unit 206. The extrusion parts include an extrusion rack 201. The extrusion rack 201 is slidably connected to the fixed ring 103. The connecting assembly 2 also includes a transmission part. The extrusion rack 201 is transmission-connected to the ring gear 104 via the transmission part. The extrusion rack 201 is used to drive the ring gear 104 to move.

[0028] When the water surface fluctuates, multiple floating components 1 squeeze each other. At this time, after the connecting component 2 is pressurized, the ball connection of the first ball pair unit 205 and the second ball pair unit 206 is used to alleviate the torque caused by the up and down drop between adjacent floating components 1. The extrusion rack 201 slides on the fixed ring 103 to alleviate the torque caused by the change in the spacing between adjacent floating components 1. After the extrusion rack 201 slides, it will drive the gear ring 104 to rotate. The third unit 204 of the extrusion cylinder drives the rotating frame 105 to rotate synchronously. During the movement of the rotating frame 105, the scraper 108 will scrape the side wall and bottom of the pontoon that are closely attached to it, effectively preventing parasites from attaching to the pontoon, which can reduce the load of the pontoon and increase the life of the pontoon.

[0029] Embodiment 2: This embodiment further expands the transmission member on the basis of the embodiment 1, specifically as follows Figure 6 , Figure 7 As shown, the transmission member includes a second gear 110 rotatably connected to the buoyancy box, the second gear 110 is meshed with the extrusion rack 201, a third gear 111 and a first gear 109 are installed on the second gear 110, the first gear 109 is meshed with the ring gear 104, a ratchet 112 is slidably connected to the third gear 111, the ratchet 112 cooperates with the first gear 109, and a second spring 113 is arranged between the ratchet 112 and the third gear 111.

[0030] When the extrusion rack 201 is pressed and slides toward the buoyancy box, it drives the second gear 110 meshing with it, and the second gear 110 drives the third gear 111. The third gear 111 makes the first gear 109 rotate synchronously through the ratchet 112, and the first gear 109 drives the ring gear 104 to rotate; when the extrusion rack 201 is reset away from the buoyancy box, the extrusion rack 201 still drives the second gear 110, but when the third gear 111 rotates, the ratchet 112 is squeezed by the first gear 109, causing the second spring 113 to be compressed, and the ratchet 112 retracts to the third gear 111, that is, the first gear 109 will not be driven.

[0031] When part of the extrusion rack 201 on the pontoon slides toward the pontoon, while part of the extrusion rack 201 does not slide, the sliding extrusion rack 201 will drive the gear ring 104 to rotate, so the gear ring 104 will also drive the first gear 109 in the transmission member connected to the non-sliding extrusion rack 201 to rotate. At this time, the rotation of the first gear 109 will squeeze the ratchet 112, causing the ratchet 112 to retract. Therefore, each extrusion rack 201 connected to the pontoon can operate independently without affecting each other.

[0032] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0033] Embodiment 3: This embodiment is further expanded on the basis of Embodiment 1. Figure 5 As shown, the rotating frame 105 is equipped with a blade 106 .

[0034] When the rotating frame 105 rotates, the paddle blades 106 rotate synchronously. The paddle blades 106 rotate in the water. On the one hand, they can provide upward lift for the pontoon to prevent the pontoon from sinking too deeply into the water when the water surface fluctuates greatly, thereby further improving the stability of the pontoon. On the other hand, the paddle blades 106 will be subject to water resistance when rotating, so the reaction force of the resistance can prevent the extrusion parts from being easily squeezed, thereby reducing the impact of water surface fluctuations on the pontoon.

[0035] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0036] Embodiment 4: This embodiment further expands the extrusion part on the basis of Embodiment 3. Figure 8 As shown, the extrusion piece also includes a first extrusion cylinder unit 202, a second extrusion cylinder unit 203, and a third extrusion cylinder unit 204. The first extrusion cylinder unit 202 is threadedly connected to the second extrusion cylinder unit 203, the second extrusion cylinder unit 203 is threadedly connected to the third extrusion cylinder unit 204, and the third extrusion cylinder unit 204 is connected to the first ball pair unit 205 or the second ball pair unit 206. The extrusion rack 201 is slidably connected to the first extrusion cylinder unit 202, and the second extrusion cylinder unit 203 is provided with a cinch ring 211. The first extrusion cylinder unit 202 is provided with a fitting 210, and the fitting 210 is connected to the second extrusion cylinder unit 203. A fourth spring 209 is arranged between them, a collision block 208 is placed in the second unit 203 of the extrusion cylinder, and a third spring 207 is arranged between the collision block 208 and the third unit 204 of the extrusion cylinder. The fitting 210 is composed of a spherical base, a thick rod, and a thin rod in sequence, and there is a smooth transition between the thick rod and the thin rod. The inner diameter of the cuff ring 211 is the same as the diameter of the thick rod, and a slot hole is arranged on the collision block 208, and the diameter of the slot hole is the same as the diameter of the thin rod. The axes of the inner wall of the cuff ring 211, the slot hole, the first unit 202 of the extrusion cylinder, and the second unit 203 of the extrusion cylinder coincide with each other; a plurality of first springs 107 are axially installed along the extrusion rack 201 on the buoyancy box.

[0037] Under the action of gravity, the fitting 210 is in an inclined state, that is, the axis of the thin rod does not coincide with the axial direction of the first unit 202 of the extrusion cylinder; when the water surface fluctuates and the two floating components 1 approach each other, since the thin rod is in the cinch ring 211 and supports the impact block 208, under the action of the third spring 207, the fitting 210 and the first unit 202 of the extrusion cylinder move synchronously, and the fitting 210 supports the extrusion rack 201, and the extrusion rack 201 drives the paddle 106 and the scraper 108 to operate when it slides; when the extrusion rack 201 contacts the first spring 107, due to the supporting effect of the first spring 107, as the second unit 203 of the extrusion cylinder and the first unit 202 of the extrusion cylinder continue to approach the buoyancy box, the third spring 207 and the fourth spring 209 begin to be compressed, and then As the second unit 203 of the extrusion cylinder moves, when the cinch ring 211 moves to the junction of the thick rod and the thin rod, since the inner diameter of the cinch ring 211 is the same as the diameter of the thick rod, the posture of the fitting 210 begins to change until the thick rod is completely inserted into the cinch ring 211, and the thin rod is simultaneously inserted into the slot of the impact block 208. Then the third spring 207 begins to reset, so that the impact block 208 hits the fitting 210, and the fitting 210 transmits the impact to the extrusion rack 201 through the spherical base. At this time, the first spring 107 is squeezed, and the extrusion rack 201 is transmitted to the blade 106 and the rotating frame 105 through the transmission member, so that the rotating frame 105 and the blade 106 shake, and the parasites that may be attached to the rotating frame 105 and the blade 106 are shaken off.

[0038] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0039] Embodiment 5: This embodiment further expands the buoyancy box on the basis of the above embodiment. Figure 3 As shown, the pontoon includes a pontoon body 101 and a pontoon cover 102. The pontoon body 101 is provided with an inspection port. The pontoon cover 102 is connected to the pontoon body 101 by bolts and seals the inspection port.

[0040] When the buoyancy box 101 is broken, the buoyancy box cover 102 is opened and the buoyancy box 101 can be repaired from the inside, which is convenient and can ensure the quality of the repair.

[0041] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0042] Embodiment 6: This embodiment further expands the power generation component 3 on the basis of the above embodiment. Figure 2 As shown, the power generation assembly 3 includes a photovoltaic panel 301 and a support rod. A plurality of the support rods are installed on the buoyancy box 101, and the photovoltaic panel 301 is installed on the support rod.

[0043] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0044] Embodiment 7: This embodiment further expands the power generation component 3 on the basis of embodiment 6. Figure 2 As shown, the support rod includes a second support rod 303 and a first support rod 302. The first support rod 302 is slidably connected to the second support rod 303, and the multiple support rods are independently adjusted.

[0045] By adjusting the height of each support rod, the orientation of the photovoltaic panel 301 can be adjusted to maximize the power generation efficiency of the photovoltaic panel 301 .

[0046] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
