Description

Technical Field

[0001] The invention relates to the field of photovoltaic technology, in particular to a photovoltaic power station component. Background Art

[0002] "Fish-photovoltaic complementarity" refers to the combination of fishery farming and photovoltaic power generation. A photovoltaic panel array is set up above the surface of the fish pond, and fish, shrimp and crabs can be farmed in the water below the photovoltaic panels. The photovoltaic array can also provide good shielding for fish, shrimp and crabs, preventing the high temperature in summer from affecting their normal growth.

[0003] There have been some studies on photovoltaic fish ponds in the prior art. For example, a floating photovoltaic power station disclosed in a Chinese invention patent application with publication number CN115378346A includes a flexible pad fixed to a ring-shaped elongated floating element surrounding the pad, the flexible pad is arranged on the surface of the water body and in contact with the water body, and the flexible pad has a plurality of photovoltaic modules fixed on the pad and surrounded by the floating element, so that the flexible pad is located inside the floating element. Another example is a photovoltaic bracket for photovoltaic fish ponds disclosed in a Chinese invention patent with publication number CN111802315B, including a photovoltaic bracket, a plurality of photovoltaic brackets are evenly and matrix-distributed in the pond, a transfer mechanism that can slide up and down on the photovoltaic bracket is provided on the photovoltaic bracket, and the transfer mechanisms on adjacent photovoltaic brackets in the same row in a fixed direction are connected by an air pipe that can oxygenate the pond, and a fishing net is fixedly connected to the bottom of the air pipe.

[0004] The traditional photovoltaic fish pond is to install columns at the bottom of the fish pond, and install brackets and photovoltaic panels on the top of the columns. In actual use, this method requires the columns to be installed underground at the bottom of the pond, which is not only costly, but also causes many inconveniences for the later fishing and dredging of the fish pond. Therefore, more and more photovoltaic fish ponds have begun to use floating photovoltaic modules, that is, photovoltaic panels are installed on floating objects, and the floating objects float on the water surface. When fishing and dredging, the floating photovoltaic modules are collected to free up space on the pond surface. The existing floating photovoltaic modules need to be moved out of the fish pond as a whole when collected, which requires a large space and is inconvenient to operate, and it is easy to cause damage to the photovoltaic modules. Summary of the invention

[0005] The object of the present invention is to provide a photovoltaic power station component to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a photovoltaic power station component, comprising a plurality of floating rows, on which a plurality of bases are evenly installed along the length direction, and photovoltaic units are rotatably installed on the bases; the floating rows are parallel to each other, and a plurality of connecting rods are rotatably installed on both sides of the floating rows; a mounting frame parallel to the floating rows is arranged between two adjacent floating rows, and the corresponding connecting rods on the two adjacent floating rows are rotatably installed on the mounting frame, and a strip-shaped air bag is fixedly installed on the bottom of the mounting frame.

[0007] As a preferred technical solution of the present invention, a counterweight plate is fixedly installed at the bottom of the airbag; the end of the connecting rod connected to the floating row is lower than the end of the connecting rod connected to the mounting frame.

[0008] As a preferred technical solution of the present invention, the photovoltaic unit includes a photovoltaic panel and a frame for supporting the photovoltaic panel, the frame is rotatably matched with the base, and a wing plate is fixedly installed on the frame, and a baffle rod matching the wing plate is fixedly installed on the base.

[0009] As a preferred technical solution of the present invention, a hook is provided at the edge of the photovoltaic panel, a rope is connected to the hook, and the bottom end of the rope is connected to a feeding trough through a hook; a pressure plate is fixedly installed on the base, and an elastic part is fixedly connected between the pressure plate and the wing plate.

[0010] As a preferred technical solution of the present invention, the photovoltaic unit has a stable state and an unstable state; in the stable state, the wing plate is in contact with the barrier rod, and the photovoltaic panel is in an inclined state; in the stable state, the trough corresponding to the photovoltaic panel corresponds to the lower edge of the adjacent photovoltaic panel up and down.

[0011] As a preferred technical solution of the present invention, the trough includes an arc-shaped bottom plate and an end plate located at the end of the bottom plate, and a plurality of hollow grooves are opened on the bottom plate.

[0012] As a preferred technical solution of the present invention, an arc-shaped inner lining plate is movably installed on the bottom plate, and the inner lining plate has a first state of being in contact with the bottom plate and a second state of being separated from the bottom plate; a through groove corresponding to the hollow groove is opened on the inner lining plate.

[0013] As a preferred technical solution of the present invention, a protruding circular shaft is formed on the top of the inner lining plate and is rotatably matched with the bottom plate through the circular shaft, and the axis of the circular shaft is parallel to the top edge of the bottom plate.

[0014] As a preferred technical solution of the present invention, a gear is fixedly sleeved on the circular shaft, a cross bar is fixedly installed on the floating row, a rack matching the gear is vertically fixedly installed on the cross bar, and a limit rod for horizontally limiting the gear is also vertically fixedly installed on the cross bar.

[0015] In the above technical scheme, the present invention provides a photovoltaic power station component, in which photovoltaic units are evenly arranged on floating rows, and the airbags between adjacent floating rows are kept inflated, that is, the airbags are subject to a certain buoyancy. When the floating rows tend to move horizontally under the action of wind or other external forces, the buoyancy of the airbags will support the floating rows horizontally through the connecting rods to ensure that the distance between the floating rows remains unchanged under normal working conditions, that is, the photovoltaic panels will not block each other; when it is necessary to fish and dredge the fish pond, it is only necessary to deflate the airbags to eliminate the buoyancy of the airbags, and the floating rows can be moved closer to each other, thereby freeing up space on the pond surface for fishing and dredging. There is no need to move the photovoltaic component out of the fish pond as a whole, which not only improves the convenience of operation, but also avoids damage to the photovoltaic component. In addition, when the outside temperature is low, the volume of the airbag is small and the distance between each floating row is large. External light can shine through the gaps between the photovoltaic panels onto the pond surface to raise the water temperature to a suitable temperature range. When the outside temperature is high, the volume of the airbag expands and the distance between each floating row decreases. The photovoltaic panels block external light to prevent it from directly shining on the pond surface, thereby preventing the water temperature from being too high and affecting the normal growth of fish.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a photovoltaic power station component, including a plurality of long strips of floating rows 1, the longitudinal section of the floating rows 1 is rectangular; the floating rows 1 are made of a material with a density less than that of water (such as foam and wood), and the floating rows 1 are wrapped with a waterproof layer; a plurality of bases 2 are evenly installed on the upper surface of the floating rows 1 along its length direction, and a photovoltaic unit 3 is rotatably installed on the base 2; each floating row 1 is parallel to each other, and connecting rods 4 are rotatably installed on both sides of the floating rows 1, and the number of connecting rods 4 on both sides of the floating rows 1 is the same and the positions are corresponding; a mounting frame 5 parallel to the floating rows 1 is arranged between two adjacent floating rows 1, and the corresponding connecting rods 4 on the two adjacent floating rows 1 are rotatably installed on the mounting frame 5, and a strip-shaped airbag 6 is fixedly installed at the bottom of the mounting frame 5, and the airbag 6 can be inflated and deflated; a counterweight plate 7 is fixedly installed at the bottom of the airbag 6; the end of the connecting rod 4 connected to the floating row 1 is lower than the end of the connecting rod 4 connected to the mounting frame 5.

[0028] Specifically, under normal circumstances, each floating row 1 floats on the pond surface, and the airbag 6 is inflated (not fully filled). The airbag 6 is subjected to the buoyancy of the water and floats on the pond surface. The counterweight plate 7 exerts a downward force on the airbag 6, and the airbag 6 is in a balanced state, that is, the depth of the airbag 6 in the water is constant; when the floating row 1 and the photovoltaic unit 3 are subjected to a horizontal external force (such as wind force), a horizontal force is exerted on the connecting rod 4, and the connecting rod 4 has a tendency to rotate. The mounting frame 5, the airbag 6 and the counterweight plate 7 have a tendency to move downward, but the buoyancy of the water will prevent the airbag 6 from descending, so the connecting rod 4 will not rotate significantly, that is, the connecting rod 4 plays a role of horizontal support for the floating row 1, ensuring that the distance between the two floating rows 1 is constant (not completely constant, and is allowed to vary within a very small range); in this way, the photovoltaic units 3 on two adjacent floating rows 1 will not be blocked due to being close to each other.

[0029] When the fish pond needs to be fished or dredged, the air bags 6 are first deflated, and the air bags 6 are no longer affected by buoyancy. In this way, the operator can push the floating rows 1 horizontally on the shore to make the floating rows 1 close to each other, thereby reducing the pond surface occupied by all the floating rows 1 as a whole and freeing up the required space.

[0030] It should be noted that the airbag 6 is not fully filled when inflated; when the air temperature is low, the air temperature in the airbag 6 is also low, the volume of the airbag 6 is small, and the buoyancy it receives is also small. The gravity of the counterweight plate 7 causes the airbag 6 and the mounting frame 5 to be in a lower position, and the inclination angle of the connecting rod 4 is small, that is, the distance between two adjacent floating rows 1 is large, and external light can irradiate the pond surface through the gap between the photovoltaic units 3 on adjacent floating rows 1, thereby preventing the water temperature in the fish pond from being too low; when the air temperature is high, the air temperature in the airbag 6 is also high, the volume of the airbag 6 expands, and the buoyancy it receives is also large. The airbag 6 and the mounting frame 5 are in a higher position, and the inclination angle of the connecting rod 4 is large, that is, the distance between two adjacent floating rows 1 is small, and the photovoltaic units 3 on adjacent floating rows 1 completely block the light, thereby preventing the light from irradiating the pond surface through the gap between adjacent photovoltaic units 3, thereby preventing the water temperature in the fish pond from being too high.

[0031] To sum up, in this embodiment, by inflating the airbag 6, it can be ensured that the photovoltaic units 3 will not block each other during normal operation; after the airbag 6 is deflated, the various floating rows 1 can be close to each other to make room for the pond surface; and when the temperature is low, light can shine on the pond surface through the gaps between the photovoltaic units 3, and when the temperature is high, the photovoltaic units 3 can completely block the light.

[0032] Example 2

[0033] Photovoltaic fish ponds with larger areas are generally fed by drones, that is, the drones spread feed along a predetermined route on the pond surface; in order to receive more light, the inclination angle of the photovoltaic panels generally does not exceed 20°; most of the feed will slide down the photovoltaic panels to the pond surface after falling on the photovoltaic panels, but due to the limited inclination angle of the photovoltaic panels, a small amount of feed will remain on the photovoltaic panels; if the residual feed is not cleaned up, the light-receiving area of ​​the photovoltaic panels will be affected; the commonly used method is that the drones sprinkle water after spreading the feed, and the water falling on the photovoltaic panels drives the residual feed to flow into the fish pond, but this requires a large amount of water, and a small amount of water can not only fail to remove the residual feed, but will make the feed soft and adhere to the photovoltaic panels; the operator has to control the drone to sprinkle water many times, and needs to prepare a lot of batteries to maintain the long-term endurance of the drone, which consumes a lot of manpower and material resources; based on this, this embodiment is designed as follows.

[0034] like Figure 3As shown, based on the previous embodiment, in this embodiment, the photovoltaic unit 3 includes a photovoltaic panel 301 and a frame 302 for supporting the photovoltaic panel 301, the frame 302 is rotatably matched with the base 2, and a wing plate 303 is fixedly installed on the frame 302, and a baffle 8 matched with the wing plate 303 is fixedly installed on the base 2; the photovoltaic unit 3 has a stable state and an unstable state; in the stable state, the wing plate 303 is in contact with the baffle 8, and the photovoltaic panel 301 is in an inclined state, that is, Figure 3 After the drone finishes feeding, the higher end of the photovoltaic panel 301 is pulled downward by external force, so that the photovoltaic unit 3 enters an unstable state, and then the external force on the photovoltaic panel 301 is released, and the photovoltaic panel 301 will automatically rotate to the position under the action of gravity. Figure 3 The photovoltaic panel 301 rotates to a stationary state, and the remaining feed on the photovoltaic panel 301 will slide down the surface of the photovoltaic panel 301 into the fish pond under the action of inertia. It should be noted that in the prior art, a driving unit is arranged in the base 2 to drive the photovoltaic panel 301 to rotate to a larger angle, so that the remaining feed falls into the fish pond under the action of gravity; however, this method requires that each photovoltaic unit 3 is equipped with a driving part, which is costly; and there is a lot of water vapor on the fish pond, and the electric components are prone to poor contact and other faults.

[0035] like Figure 3 As shown, the photovoltaic panel 301 is provided with a hook at the upper edge in a stable state, a rope 9 is connected to the hook, and the bottom end of the rope 9 is connected to a trough 10 through a hook; in a stable state, the trough 10 corresponding to the photovoltaic panel 301 corresponds to the lower edge of the adjacent photovoltaic panel 301 in the upper and lower directions; a pressure plate 11 is fixedly installed on the base 2, and an elastic member 12 is fixedly connected between the pressure plate 11 and the wing plate 303.

[0036] Specifically, the feed that slides down from the photovoltaic panel 301 contacts the water surface and sinks into the feeding trough 10. The fish will swim along with the food, and the fish will constantly swing their bodies during the feeding process. Therefore, the fish will push the feeding trough 10 down during the feeding process. The feeding trough 10 drives the higher end of the photovoltaic panel 301 to descend through the rope 9, and the photovoltaic panel 301 rotates. The photovoltaic unit 3 enters an unstable state, and the elastic member 12 is deformed and stores energy under pressure. After the fish finish eating, they leave the feeding trough 10. The feeding trough 10 is no longer pushed by the fish, and the elastic member 12 recovers and promotes the photovoltaic panel 301 to rotate in the opposite direction. Figure 3 status.

[0037] like Figure 4 , Figure 5 and Figure 6As shown, the feeding trough 10 comprises an arc-shaped bottom plate 1001 and an end plate 1002 located at the end of the bottom plate 1001. The bottom plate 1001 is provided with a plurality of hollow grooves 1003, and the uneaten feed of the fish will sink through the hollow grooves 1003 and will not remain in the feeding trough 10. An arc-shaped inner lining plate 1004 is movably mounted on the bottom plate 1001, and the inner lining plate 1004 has a first state ( Figure 6 As shown), and a second state in which it is separated from the bottom plate 1001; in the first state, the lower surface of the inner lining plate 1004 is in contact with the upper surface of the bottom plate 1001; the inner lining plate 1004 is also provided with a through groove 1005 corresponding to the hollow groove 1003; a raised circular shaft 1006 is formed on the top of the inner lining plate 1004 and is rotatably matched with the bottom plate 1001 through the circular shaft 1006, and the axis of the circular shaft 1006 is parallel to the top edge of the bottom plate 1001; a gear 1007 is fixedly sleeved on the circular shaft 1006, a cross bar 13 is fixedly installed on the floating row 1, a rack 14 matching the gear 1007 is vertically fixedly installed on the cross bar 13, and a limit rod 15 for horizontally limiting the gear 1007 is also vertically fixedly installed on the cross bar 13.

[0038] Specifically, in the initial state, the gear 1007 and the rack 14 are in a separated state, the feed falls into the trough 10 and is deposited on the inner lining plate 1004, and the fish pushes the trough 10 to sink vertically during the process of eating in the trough 10. During the vertical sinking of the trough 10, the gear 1007 and the rack 14 enter into a meshing state, the gear 1007 rolls, and drives the circular shaft 1006 and the inner lining plate 1004 to rotate relative to the bottom plate 1001, and the inner lining plate 1004 is separated from the bottom plate 1001; when the inner lining plate 1004 rotates relative to the bottom plate 1001, on the one hand, part of the feed is thrown out of the trough 10, and on the other hand, the fish are dispersed. Most of the fish eating in the trough 10 will quickly swim away from the trough 10, that is, the trough 10 will suddenly lose the vertical downward force, and the gravity of the photovoltaic panel 301 itself and the resilience of the elastic member 12 will drive the photovoltaic panel 301 and the wing plate 303 to rotate quickly to Figure 3 state (ie, the wing plate 303 is in contact with the barrier rod 8); the residual feed on the photovoltaic panel 301 will slide down under the action of a larger inertial force.

[0039] In summary, in this embodiment, when the feeding trough 10 sinks to a certain depth, the fish will quickly swim away from the feeding trough 10, so that the photovoltaic panel 301 can rotate quickly, thereby increasing the inertia of the feed on the photovoltaic panel 301 and promoting the sliding of the feed.

[0040] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
