Description

Technical Field

[0001] The utility model relates to the technical field of floating photovoltaic power generation, in particular to a truss netting floating type water surface photovoltaic power station system. Background Art

[0002] A water surface photovoltaic power station is an innovative way of photovoltaic power generation utilization. It installs photovoltaic modules on water surface floating bodies, realizing the complementary advantages of water area and photovoltaic power generation. Water surface photovoltaic power stations are mainly divided into two categories: pile foundation fixed type and floating type, which are applicable to water surfaces such as ponds, small and medium-sized natural lakes, reservoirs, water storage ponds, and lakes formed by coal mining subsidence areas. Among them, the floating type water surface photovoltaic power station can better solve the problems of power shortage and new energy consumption in waterfront cities, and has the advantages of high power generation efficiency, flexible layout, and no occupation of land resources. In order to eliminate the long-term jolting caused by water surface fluctuations to the system, a flexible connection method needs to be selected to improve the durability of the power station connection system.

[0003] However, the existing flexible connection systems or methods often have complex structures, need to rely on components such as pressure rods, rotating rods, and springs, or simply rely on the toughness of the floating body polymer material to eliminate the vibration of the floating body. They often have poor durability, cannot meet the design life requirements of power stations or water surface buildings, and have high operation and maintenance difficulty and cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a truss netting floating type water surface photovoltaic power station system aiming at the defects of the existing technology.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A truss netting floating type water surface photovoltaic power station system includes a floating body platform arranged on the water surface, a sunken anchor arranged underwater, and photovoltaic panels arranged on the floating body platform. It is characterized in that: it further includes a framework cable, a truss, and a buoy. The framework cable is arranged vertically and horizontally inside the truss to form a number of grids, and both ends of the framework cable are fixed on the truss and extend outward from the truss. The floating body platform is arranged within the grids. A number of lugs are arranged at the edge of the floating body platform. The lugs are connected to the framework cable through connecting ropes. The buoy is connected to the part of the framework cable extending outward. The sunken anchor is connected to the lower end of the buoy.

[0007] Further, node clamps are arranged at the intersections of the framework cables. The framework cables are fixedly connected to each other through the node clamps. The connecting ropes are connected to the framework cables through the node clamps.

[0008] Further, a vibration allowance is left for the length of the connecting rope. The floating body platform can vibrate up and down in the grids formed by the framework cables.

[0009] Furthermore, there is a smooth transition between the outer contour of the ear and the outer contour of the floating body platform.

[0010] Furthermore, the floating body platform is rectangular in shape, and the ears are arranged at the four corners of the floating body platform.

[0011] Furthermore, the truss is circular or rectangular in shape.

[0012] Furthermore, at least three groups of buoys and sinker anchors are arranged on each side of the truss, and the skeleton ropes are grouped and connected to different buoys.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Compared with the existing flexible connection system of floating body platforms, the present utility model does not involve complex mechanical components and processing techniques. Only ropes and fixtures are required to achieve the flexible connection of the array. The floating body platform can use HDPE floating boxes with mature technology and low prices, and the fixtures are made of materials such as alloys with higher hardness and wear resistance, which can effectively reduce the construction cost.

[0015] 2. The overall shape of the floating body platform is regular, which is beneficial to reducing the transportation and storage costs, and reducing the gaps in the array, ensuring that the array provides sufficient buoyancy and support per unit area.

[0016] 3. The main parts subject to wear in the truss array are the ears and the connecting ropes. When damage occurs, it will not affect the overall stability of the array system, and the operation and maintenance difficulty is relatively low. The truss is a rigid structure, and there is a certain distance between the truss and the floating body platform array. Combined with the anchoring system, it can play a certain role in wave dissipation and wave prevention in a windy and wavy environment.

[0017] 4. The overall flexible connection solution combining the truss and the skeleton rope net has good stability and high force transmission efficiency. Compared with the existing water power station scheme of large truss floating high platforms, the cost per watt of this photovoltaic power station system is lower, and it is easier to construct and install.

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. This embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix", "set" and the like 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 an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. 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] Figures 1-3 The specific embodiment of a truss net-type floating water photovoltaic power station system is shown, including a floating platform 1, a connecting rope 2, a skeleton cable 3, a node clamp 4, a truss 5, a buoy 6 and a sinking anchor 7. The overall structure is as follows Figure 1 , 2 shown.

[0026] like Figure 1 As shown, the skeleton cables 3 are arranged vertically and horizontally inside the truss 5 to form a plurality of grids, and the floating platform 1 is arranged in the grids. Both ends of the skeleton cables 3 extend outside the truss 5 and are fixedly connected at the places where they pass through the truss 5. The skeleton cables 3 extending outside the truss 5 are grouped and connected to the buoys 6 arranged on each side of the truss, reducing the stress angle of the skeleton cables 3 on both sides of the truss 5 and relieving the extreme stress of the truss 5.

[0027] like Figure 2 As shown, an anchor 7 is arranged under each buoy 6 as an anchoring system of the power station array. The specific design of the anchor 7 is designed according to the actual situation.

[0028] As Figure 3 shown, at each crossing of the skeleton cable 3, a node fixture 4 is provided to fix the crossing points of the skeleton cable 3, improve the overall force transmission efficiency of the skeleton cable 3, and avoid friction at the crossings.

[0029] The floating body platform 1 provides buoyancy for the whole system. The floating body platform 1 adopted has a rectangular shape. There are four lugs 11 on each floating body platform, and the four lugs 11 are respectively located at the four corners of the rectangular floating body platform 1. The outer contour of the lug 11 and the outer contour of the floating body platform 1 are smoothly transitioned as a whole to form a regular geometric body, which is beneficial to reducing the gap between the floating body platforms 1 and improving the overall space utilization rate of the array. Photovoltaic panels 12 are installed on the floating body platform 1, and power station equipment such as busbar boxes and inverters can also be installed according to needs. The connecting rope 2 connects the lug 11 of the floating body platform 1 with the node fixture 4 and leaves a vibration margin length, so that each floating body platform 1 can vibrate slightly in the grid formed by the skeleton cable 3. When encountering large wind and wave impacts, the main force is borne by the skeleton cable 3, reducing the mechanical strength requirements for the lugs under strict working conditions.

[0030] Preferably, the overall planar shape of the adopted truss 5 is circular.

[0031] It should be noted that in other examples, the planar shape of the truss 5 can be rectangular or other shapes, and the outer shape of the floating body platform 1 and the number and position of the lugs 11 can all change.

[0032] The above specific implementation manners are only for illustrating the technical concept and structural features of the present invention, aiming to enable those skilled in the art to implement it accordingly. However, the above content does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention shall fall within the protection scope of the present invention.
