Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaic power generation, and in particular relates to a cable bridge used for fish-photovoltaic complementarity. Background Art
[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.
[0003] Fishery-photovoltaic complementarity refers to the combination of fishery farming and photovoltaic power generation. Photovoltaic panel arrays are set up above fish ponds and aquaculture water surfaces, and fish and shrimp can be farmed in the waters below the photovoltaic panels. The photovoltaic arrays can also provide good shielding for fish farming, forming a new power generation model of "generating electricity above and farming fish below".
[0004] The fish-photovoltaic complementary power generation model innovatively combines photovoltaics and fisheries, two industries that occupy a large amount of land resources, killing two birds with one stone. It not only achieves three-dimensional spatial reuse and saves land, but also outputs environmentally friendly clean energy.
[0005] At present, the cables of the fish-solar complementary power station are usually laid in the form of bridges, and the cable bridges are installed on the cross arms of the clamps fixed on the piles. The specification requires that when laying cables using ladder racks and trays, the relative deflection value under the action of the safe working load should be allowed: steel should not be greater than 1 / 200, and aluminum alloy should not be greater than 1 / 300.
[0006] In the design of floating photovoltaic power stations, the distance between the front and rear rows of piles is generally large. In order to meet the requirements of the regulations, a pipe pile for supporting the cable bridge will be added between the front and rear pile foundations. For this fixed bridge installation method, the cable bridge elevation must meet the flood level requirements, but at the same time, it must meet the needs of later photovoltaic operation and maintenance and fish and shrimp farming passage space. This means that the cable bridge is too low and cannot meet the requirements of later operation and maintenance and fish and shrimp farming passage. The cable bridge needs to be raised to raise the pipe pile elevation, which leads to increased costs. Utility Model Content
[0007] In order to solve the above problems, the utility model proposes a cable bridge for fish-light complementarity, which not only helps to improve the patency of the fish pond space, but also reduces the construction cost.
[0008] According to some embodiments, the utility model adopts the following technical solutions:
[0009] In the first aspect, a cable bridge for fish-photovoltaic complementarity is proposed, comprising a ladder-shaped bridge arranged between two adjacent photovoltaic pipe piles and a bridge pipe pile supporting the ladder-shaped bridge;
[0010] The ladder-shaped bridge frame includes a first cross brace, a second cross brace, a third cross brace, a fourth cross brace and a fifth cross brace connected in sequence, the first cross brace and the fifth cross brace are respectively fixed on two photovoltaic tube piles, the first cross brace, the third cross brace and the fifth cross brace are parallel to the horizontal plane, and the first cross brace and the fifth cross brace have the same height and are lower than the height of the third cross brace;
[0011] The bridge frame pipe pile is arranged at the bottom of the third cross brace, and the distance from the bridge frame pipe pile to the second cross brace is greater than the distance to the fourth cross brace, and a navigation channel is formed between the bridge frame pipe pile and the second cross brace.
[0012] Furthermore, a photovoltaic panel assembly is installed on the top of the photovoltaic pipe pile, and the ladder-shaped bridge is arranged below the photovoltaic panel assembly.
[0013] Furthermore, the photovoltaic panel assembly includes a photovoltaic panel, at least two channel steel diagonal braces and at least two channel steel vertical braces; the channel steel diagonal braces and the channel steel vertical braces are fixed on the top of the photovoltaic pipe piles, and the photovoltaic panel is arranged on the top of the channel steel diagonal braces and the channel steel vertical braces, and forms a certain angle with the horizontal plane.
[0014] Furthermore, the second cross brace and the fourth cross brace are equal in length.
[0015] Furthermore, the distances from the bridge pipe pile to the two photovoltaic pipe piles are equal.
[0016] Furthermore, the photovoltaic pipe piles and bridge pipe piles are both prestressed high-strength concrete pipe piles.
[0017] Furthermore, two adjacent ladder-shaped bridge frames share a first cross brace or a fifth cross brace.
[0018] Furthermore, the first horizontal brace is connected to an oblique brace, one end of the oblique brace is connected to the first horizontal brace, and the other end is connected to the photovoltaic tube pile, and the photovoltaic tube pile, the oblique brace and the first horizontal brace form a triangle.
[0019] Furthermore, the fifth horizontal brace is connected with an oblique brace, one end of the oblique brace is connected to the fifth horizontal brace, and the other end is connected to the photovoltaic tube pile, and the photovoltaic tube pile, the oblique brace and the fifth horizontal brace form a triangle.
[0020] Furthermore, the first cross brace, the second cross brace, the third cross brace, the fourth cross brace and the fifth cross brace are all fixed with at least two trough box lateral supports for fixing the cable trough box.
[0021] Compared with the prior art, the beneficial effects of the utility model are:
[0022] The utility model provides a cable bridge for fish-photovoltaic complementarity, which utilizes the trapezoidal setting of the cable bridge, which not only helps to improve the smoothness of the fish pond space, but also eliminates the need to increase the elevation of the photovoltaic pipe piles according to the requirements of later operation and maintenance and fish and shrimp farming, thereby effectively reducing the length of the photovoltaic pipe piles and reducing project construction costs.
[0023] The utility model provides a cable bridge for fish-photovoltaic complementarity. The cable bridge is trapezoidal. In view of the problem that the span of the front and rear rows of photovoltaic pipe piles is large, the setting position of the bridge pipe piles is optimized. The distance from the bridge pipe piles to the second cross brace is greater than the distance to the fourth cross brace. Only one fixed bridge pipe pile needs to be added in the middle, which saves cost compared with the design of setting pipe piles on both sides of a conventional arch bridge.

[0035] The present embodiment provides a cable bridge for fish-photovoltaic complementarity, comprising a ladder-shaped bridge 2 arranged between two adjacent photovoltaic tube piles 1 and bridge tube piles 3 supporting the ladder-shaped bridge 2 .
[0036] The photovoltaic pipe piles 1 and the bridge pipe piles 3 are both made of prestressed high-strength concrete (PHC) pipe piles.
[0037] The photovoltaic panel assembly is installed on the top of the photovoltaic pipe pile 1, and the photovoltaic panel assembly includes a photovoltaic panel 8, at least two channel steel diagonal braces 9 and at least two channel steel vertical braces 10. The channel steel diagonal braces and the channel steel vertical braces are fixed to the top of the photovoltaic pipe pile 1 through steel clamps, and the photovoltaic panel is arranged on the top of the channel steel diagonal braces and the channel steel vertical braces, and is at a certain angle to the horizontal plane.
[0038] The ladder-shaped bridge frame 2 is arranged below the photovoltaic panel assembly.
[0039] The ladder bridge 2 is composed of five sections, including the first cross brace 201, the second cross brace 202, the third cross brace 203, the fourth cross brace 204 and the fifth cross brace 205 connected in sequence. The first cross brace 201 and the fifth cross brace 205 are respectively fixed on the two photovoltaic tube piles 1 through the steel clamp 5, the first cross brace 201, the third cross brace 203 and the fifth cross brace 205 are parallel to the horizontal plane, the first cross brace 201 and the fifth cross brace 205 are of the same height, the height of the third cross brace 203 is higher than the height of the first cross brace 201 and the fifth cross brace 205, the second cross brace 202 is used to connect the first cross brace 201 and the third cross brace 203, the fourth cross brace 204 is used to connect the third cross brace 203 and the fifth cross brace 205, and the second cross brace 202 and the fourth cross brace 204 are at a certain angle to the horizontal plane.
[0040] The bridge pipe pile 3 is arranged at the bottom of the third cross brace 203 .
[0041] like Figure 1 As shown, if the horizontal distance from the axis of the left photovoltaic tube pile 1 (the photovoltaic tube pile facing away from the trapezoidal bridge 2) to the connection between the first cross brace 201 and the second cross brace 202 is A, the horizontal distance from the connection between the first cross brace 201 and the second cross brace 202 to the connection between the second cross brace 202 and the third cross brace 203 is B, the horizontal distance from the connection between the second cross brace 202 and the third cross brace 203 to the axis of the bridge tube pile 3 is C, the horizontal distance from the axis of the bridge tube pile 3 to the connection between the third cross brace 203 and the fourth cross brace 204 is D, the horizontal distance from the connection between the third cross brace 203 and the fourth cross brace 204 to the connection between the fourth cross brace 204 and the fifth cross brace 205 is =E, the horizontal distance from the connection of the fourth cross brace 204 and the fifth cross brace 205 to the axis of the right photovoltaic pipe pile 1 (the photovoltaic pipe pile that over-trapezoidal bridge 2) is F; then, A+B+C=D+E+F (i.e., the distances from the two photovoltaic pipe piles 1 to the bridge pipe pile 3 are equal), and B=E (i.e., the lengths of the second cross brace 202 and the fourth cross brace 204 are equal), C>D (i.e., the distance from the bridge pipe pile 3 to the second cross brace 202 is greater than the distance from the bridge pipe pile 3 to the fourth cross brace 204); therefore, a navigation channel is formed between the bridge pipe pile 3 and the second cross brace 202, the width of the navigation channel is C, and the height of the navigation channel is the difference between the elevation of the third cross brace 203 and the water surface elevation. The ships for later fishery production and photovoltaic operation and maintenance operations operate in the navigation channel.

Assuming that the length of the cable trough box 4 on the first cross brace 201, the second cross brace 202, the third cross brace 203, the fourth cross brace 204 or the fifth cross brace 205 is B, the distance between the two farthest sides of the two trough box lateral supports 7 is B+5, and the distance between the central axes of the two trough box lateral supports 7 is B-40.

[0046] The present embodiment provides a cable bridge for fish-photovoltaic complementarity, which is applied to the installation of cable bridges in fish-photovoltaic complementarity projects. The design requirements of the existing flood level are used to determine the elevation of photovoltaic pipe piles. There is no need to increase the elevation of photovoltaic pipe piles according to the requirements of later operation and maintenance and fish and shrimp farming, thereby effectively reducing the length of photovoltaic pipe piles and reducing project construction costs.
