Description

Technical Field

[0001] The utility model belongs to the field of offshore photovoltaic power generation, and in particular relates to a plate-type pile cable connection structure for offshore suspended photovoltaic power generation. Background Art

[0002] In recent years, with the rapid development of onshore photovoltaics, available land for photovoltaic construction in my country's southeastern coastal areas has become increasingly scarce. Furthermore, the high power losses associated with using western regions have led to a gradual shift in photovoltaic construction to offshore locations. Compared to traditional onshore photovoltaics, offshore photovoltaics must withstand not only their own weight, wind, snow, and earthquake loads, but also wave and current loads, with wave and current loads being the controlling loads.

[0003] Wave and current loads primarily act on the foundation piles of photovoltaic mounts. To control project costs, the use of piles must be reduced. The use of large-span suspension photovoltaic mounts can effectively reduce the use of piles, but this presents the problem of difficulty in connecting the pile heads. Conventional pile-cable connection structures are complex and require a large number of workers to perform pile-head connection work, which poses significant risks to offshore photovoltaic construction. Therefore, the following issues must be addressed regarding the pile-cable connection structure for offshore suspension photovoltaics:

[0004] (1) Construction difficulty: The traditional pile-cable connection section structure has high requirements for the accuracy of pile foundation construction. When the reserved hole of the pile foundation and the upper pile-cable connection structure are offset, the upper beams and cables cannot be installed normally, and the subsequent adjustment is difficult, which brings great trouble to the construction, affects the construction efficiency and increases the construction cost.

[0005] (2) Load transfer problem: ① Some pile-cable connection structures adopt a clamp plate connection scheme. The suspension photovoltaic pile-cable connection structure needs to bear a large pull-out force. When a suspension photovoltaic structure with a larger span is used, the pull-out force is also larger. The clamp plate connection scheme cannot meet the load transfer requirements in the suspension photovoltaic bracket when the span is larger. ② The tension of the offshore suspension photovoltaic cable is large. The traditional pile-cable connection structure will transfer the tension of the cable to the pile and then to the adjacent cable structure, which greatly increases the engineering workload of the pile foundation.

[0006] (3) Material cost issue: The traditional pile-cable connection section structure is relatively complex and requires the use of a relatively complex double-end plate, rib, and reinforcement system. The overall steel consumption is large, and the cost of the pile-cable connection structure is also high. Utility Model Content

[0007] In order to solve the above problems, the utility model provides a plate-type pile cable connection structure for offshore suspension photovoltaics.

[0008] The utility model is achieved through the following technical solutions.

[0009] The utility model provides a plate-type pile cable connection structure for offshore suspension photovoltaics, comprising a connection plate, wherein a plurality of waist holes are arranged in a circumferential direction on the upper edge of the connection plate, and the connection plate is fixed to the top of the offshore suspension photovoltaic pile through pile connection bolts and the waist holes.

[0010] Furthermore, the connecting plate is circular or polygonal, and the polygon is a regular polygon or a scalene polygon, and the regular polygon is such as a regular hexagon or a regular octagon.

[0011] Furthermore, beam connecting plates are symmetrically arranged on both sides of the connecting plate, the beam connecting plates are arranged horizontally, beam connecting holes are arranged on the beam connecting plates, and the beam connecting plates are connected to the beams through beam connecting bolts and beam connecting holes.

[0012] Furthermore, cable connection plates are symmetrically arranged on both sides of the connection plate, and the cable connection plates are inclined at a certain angle, which is consistent with the connection angle of the cable structure. Cable hanging points are arranged on the cable connection plates, and the cable connection plates are connected to the cable structure through the cable hanging points.

[0013] Furthermore, the connecting plates, beam connecting plates and cable connecting plates are all metal plates with high strength, such as steel plates.

[0014] The beneficial effects of the utility model are:

[0015] 1. The technology of connecting the waist hole and the top of the offshore suspension photovoltaic pile with bolts is adopted. The construction is simple and does not require welding or grouting. It can well adapt to the mismatch of the hanging point plane angle caused by the uncertain direction of the pile, has low requirements for pile sinking, and the pile sinking construction is simple.

[0016] 2. The tension of the cable structure is transmitted by the connecting plate between the front and rear cable suspension points, and is not directly transmitted to the offshore suspension photovoltaic piles. The construction is simple and the structure is reliable.

[0017] 3. The slightly downward-inclined cable hanging point technology has a simple structure and can well adapt to the connection angle of the cable structure.

[0018] 4. The horizontal beam connection point technology is adopted, which has simple structure and easy construction.

[0019] 5. The plate-type pile-cable connection structure of the present invention uses less steel and saves cost. BRIEF DESCRIPTION OF THE DRAWINGS
