Detailed Description
For a further understanding and appreciation of the structural features and advantages achieved by the present invention, the following description is provided in connection with the accompanying drawings, which are presently preferred embodiments and are incorporated in the accompanying drawings, in which:
as shown in fig. 2 and 3, an S-shaped cable laying assembly for a photovoltaic power plant on water comprises a box transformer floating platform 1 floating on the water surface, a photovoltaic array 2 and a cable mounting assembly 3, wherein the cable mounting assembly 3 is used for cable laying and also floats on the water surface. As shown in fig. 2, one end of the cable installation assembly 3 is installed on the box transformer substation 1, and as shown in fig. 3, the other end of the cable installation assembly 3 is installed on the photovoltaic array 2.
As shown in fig. 1, the cable attachment assembly 3 is S-shaped in order to prevent the cable from being pulled between the floating bodies due to the fluctuation of the water surface (water level change).
The cable installation assembly 3 comprises a plurality of floating bodies 4 floating on the water surface and carbon corrugated pipes 5, wherein the floating bodies 4 are used for supporting cables, and the number of the floating bodies 4 can be 5-8. The cable 6 is penetrated in the carbon corrugated pipe 5, and the carbon corrugated pipe 5 provides outer protection for the cable 6. The carbon corrugated pipes 5 are arranged on the floating bodies 4, 5-8 floating bodies 4 are arranged from head to tail according to the carbon corrugated pipes 5, and 5-8 floating bodies 4 are equally distributed on the cable installation assembly 3.
As shown in fig. 4, the hollow support rods 7 are installed at both sides of the floating body 4, the hollow support rods 7 are parallel to the carbon corrugated tube 5, and the directions of both ends of the hollow support rods 7 are the same as the carbon corrugated tube 5. The hollow supporting rods 7 are internally provided with steel wire ropes 8 in a penetrating way, one ends of the steel wire ropes 8 are arranged on the box-type substation floating platform 1, and the other ends of the steel wire ropes 8 are arranged on the photovoltaic array 2. The two steel wire ropes 8 play a role in forming an integral structure by stringing the floating bodies 4, and the two steel wire ropes 8 are longer than the length between the traditional floating bodies, so that redundancy of the lengths of the steel wire ropes 8 is formed, and the S-shaped arrangement of the cable installation assembly 3 is formed. Tension springs 9 are arranged between adjacent hollow support rods 7, and the tension springs 9 are sleeved on the steel wire ropes 8, namely, the floating bodies 4 are mutually elastic, so that the purpose of the design is to avoid collision among the floating bodies 4 when the floating bodies 4 swing.
In order to facilitate the installation of the carbon bellows 5 on the floating body 4, the upper surface of the hollow support rod 7 can also be designed to be higher than the upper surface of the floating body 4. A pipeline limiting rod 10 is arranged between the two hollow supporting rods 7 of the same floating body 4, and the pipeline limiting rod 10 is positioned on the cross section of the pipeline limiting rod 10. As shown in fig. 6, the clip 11 mounts the carbon bellows 5 on the line stop lever 10.
In practical application, along with the fluctuation of the water surface, the S shape of the cable installation component 3 also generates certain deformation along with the fluctuation of the water surface; similarly, since the photovoltaic power station on water is generally fixed with the shore or fixed with the water, if the water surface elevation rises, the S-shape of the cable installation assembly 3 also generates certain deformation. And install cable installation component 3 both ends respectively on case become floating platform 1 and photovoltaic array 2, in the in-process that cable installation component 3 produced deformation, cable installation component 3 and case become floating platform 1 (photovoltaic array 2) if be hard-connected, then very easily cause cable installation component 3 and case become the junction discovery fracture of floating platform 1 (photovoltaic array 2). In particular, the water surface fluctuation causes deformation of the cable mount assembly 3, which more easily causes tearing of the connection point of the cable mount assembly 3. In order to prevent the cable installation component 3 from being broken at the joint of the box transformer substation 1 (the photovoltaic array 2), the cable installation component 3 can be installed on the box transformer substation 1 through the sliding limiting component, and in the same way, the cable installation component 3 can also be installed on the photovoltaic array 2 through the sliding limiting component.
As shown in fig. 5, the sliding limit assembly includes a cylinder 12, and the cylinder 12 is fixedly mounted on the box-section floating platform 1 (photovoltaic array 2). The inner surface of the cylinder 12 is provided with a sliding seat 13, and the sliding seat 13 is in sliding fit with the inner surface of the cylinder 12, and the sliding seat 13 can be in sliding fit with the inner surface of the cylinder 12 by a conventional mode such as a ball, a sliding groove and the like. The carbon corrugated tube 5 is arranged on the sliding seat 13, and the cable 6 is connected to the box transformer floating platform 1 (the photovoltaic array 2), so that the carbon corrugated tube 5 which is used for protecting the cable 6 is directly arranged on the sliding seat 13, and the sliding of the carbon corrugated tube 5 (the cable 6) on the box transformer floating platform 1 (the photovoltaic array 2) can be realized. When the cable installation assembly 3 swings or deforms when encountering water surface fluctuation (water level change), the carbon corrugated tube 5 connected to the box transformer floating platform 1 (photovoltaic array 2) swings along with the water surface fluctuation, so that pulling caused by the water surface fluctuation is avoided. In order to limit the swing range of the carbon bellows 5, the sliding seat 13 may be designed in a semicircular shape, and the stopper 14 may be attached to the inner surface of the cylinder 12 according to the requirement set by the swing range.
Because the cable installation component 3 is S-shaped, in practical application, the length of the cable installation component 3 between the two photovoltaic arrays 2 can be set longer, and the cable installation component is limited to be S-shaped by being matched with the steel wire rope 8. However, the difficulty in such practical use is great, and the cable mount assembly 3 is preferably deformed to conform to the fluctuation of the water surface (water level change) in order to be more preferably molded into an S shape. In this case, the number of floating bodies 4 is 7, and the tension springs 9 are designed to have different lengths.
As shown in fig. 1, 7 floats 4 are sequentially divided into a float a15, a float B16, a float C17, a float D18, a float E19, a float F20 and a float G21 from top to bottom in an S shape. The length of the tension spring 9 on the left side between the floating body A15 and the floating body B16 is longer than that of the tension spring 9 on the right side, and the floating body A15 and the floating body B16 are staggered in the up-down direction or left-right direction by the different lengths of the tension springs 9, namely, the S-shaped upper design is formed. The length of the tension spring 9 on the left between the floating body B16 and the floating body C17 is longer than that of the tension spring 9 on the right, and similarly, the upper design based on S-shape, which continues the floating body a15 and the floating body B16. The length of the tension spring 9 on the left side between the floating body C17 and the floating body D18 is equal to the tension spring 9 on the right side thereof, forming a middle design forming an S-shape. The length of the left tension spring 9 between the floating body D18 and the floating body E19 is smaller than that of the right tension spring 9, the length of the left tension spring 9 between the floating body E19 and the floating body F20 is smaller than that of the right tension spring 9, and the length of the left tension spring 9 between the floating body F20 and the floating body G21 is smaller than that of the right tension spring 9, so that an S-shaped lower design is formed by the floating body D18, the floating body E19, the floating body F20 and the floating body G21. By unequal lengths of the plurality of tension springs 9 at different positions, an overall S-shaped design of the cable mount assembly 3 is achieved.
In actual use, when the wind direction of the water surface is in a certain direction, S-shaped bending is generated among the floating bodies 4, if the floating body A15 bends to the left, the floating body B16 bends to the right, and the floating body C17 and the like are changed in sequence; when the wind direction changes, the bending direction of the floating body a15 changes, and similarly, the floating body B16, the floating body C17, and the like change in order.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims.
