Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic pile technology, specifically a large prefabricated marine photovoltaic pipe pile with a reinforced structure. Background Technology

[0002] Offshore photovoltaic power plants require large prefabricated pipe piles as a foundation for supporting the photovoltaic system. These piles are typically prefabricated in factories using high-strength concrete or steel, and are characterized by corrosion resistance, wind and wave resistance, and long-term durability. Existing steel pipe piles for offshore photovoltaic systems usually consist of three parts: a large-diameter spiral steel pipe at the bottom, a conical pipe in the middle, and a top layer steel pipe. The large-diameter spiral steel pipe is designed to be inserted well into the seabed and its spiral grooves increase the contact area with the seabed pattern, thereby increasing the pile's bearing capacity. One end of the top layer steel pipe is fixedly connected to a pile top flange for connecting the offshore photovoltaic panel support.

[0003] In the current technology, the top layer of large precast steel pipe piles used for offshore photovoltaic power generation typically consists of only one layer of steel plate. However, the top layer of steel pipe is frequently exposed to the impact of waves. The existing single-layer steel pipe is easily deformed by the impact of waves, which affects the stability and safety of the offshore photovoltaic power station. There is a lack of corresponding reinforced structures in this area, which needs to be improved and optimized. Utility Model Content

A sealing ring is inserted into one end of the fixing ring, and the other end of the sealing ring is pressed against an outer reinforcing body. A spring is fixedly connected to the other end of the fixing ring, and a pressure cover ring is fixedly connected to the other end of the spring.

[0010] Preferably, the fixing ring and the pressing cover ring are symmetrically provided with limiting insertion ports in the middle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The present invention proposes a large prefabricated pipe pile for marine photovoltaic systems with a reinforced structure. This is mainly achieved by inserting an external reinforcement body into the top steel plate and fixing it with a threaded connection of a fixing ring on a fixing component. The lifting block on the top steel pipe is further fixed by a rotating slot clamping limit block and a pressure cover ring under the action of a spring to prevent the threads from loosening.

[0021] Please see Figures 1 to 6 This utility model provides the following two technical solutions:

[0022] Example 1: A large precast offshore photovoltaic pipe pile with a reinforced structure includes a spiral pipe 1, a conical pipe 2 fixedly connected to one end of the spiral pipe 1, a top steel pipe 3 fixedly connected to the other end of the conical pipe 2, a pile top flange 4 fixedly connected to the other end of the top steel pipe 3, lifting blocks 5 symmetrically fixedly connected to both ends of the spiral pipe 1, lifting blocks 5 symmetrically fixedly connected to both ends of the top steel pipe 3, a support plate 6 fixedly connected to one end of the top steel pipe 3, a sealing groove 7 provided in the middle of the support plate 6, a sealing gasket 10 inserted into the sealing groove 7, and an external reinforcement 8 also inserted into the sealing groove 7. The other end is fixedly connected to a fixing component; one end of the support plate 6 is fixedly connected to a diagonal brace 11, and the other end of the diagonal brace 11 is fixedly connected to the vertebral canal 2; the top steel pipe 3 is symmetrically fixedly connected to two ends of a limiting plate 12, one end of the top steel pipe 3 is provided with a threaded thread 14, and the two ends of the top steel pipe 3 are symmetrically provided with limiting blocks 15; the middle of the outer reinforcement body 8 is symmetrically provided with a limiting slot 16, and the limiting plate 12 is correspondingly inserted into the limiting slot 16; one end of the outer reinforcement body 8 is provided with a scale line 13; the outer reinforcement body 8 includes a galvanized steel plate 801, and a honeycomb buffer layer 802 is fixedly connected inside the galvanized steel plate 801.

[0023] In use, a support plate 6 is fixedly connected to one end of the top steel pipe 3. The support plate 6 is fixed by multiple sets of diagonal bracing plates 11 connected to the vertebral pipe 2. One end of the support plate 6 is provided with a sealing groove 7 and an outer reinforcement 8 is inserted. A sealing gasket 10 is inserted between the two to play a sealing role. When the outer reinforcement 8 is inserted into the top steel pipe 3, the limiting slot 16 is aligned with the lifting block 5 and the limiting plate 12 on the top steel pipe 3 and inserted, and fixed by the fixing component. The outer reinforcement 8 is composed of an outer galvanized steel plate 801 and an inner honeycomb buffer layer 802. The galvanized steel plate 801 has good impact resistance and corrosion resistance. The honeycomb buffer layer 802 plays a role in buffering the impact of sea waves. The scale line 13 on the outside of the outer reinforcement 8 is used to observe the water level.

[0024] Example 2: Based on Example 1, the fixing component includes a fixing ring 901, which is threaded to the threaded wire 14. The fixing ring 901 has a rotating groove 902 in the middle, and a limiting block 15 is rotatably engaged in the rotating groove 902.

The fixing ring 901 is rotated to make the threaded connection. After rotation, the limiting block 15 is also locked into the rotating groove 902.
