Description

Technical Field

[0001] This utility model relates to the technical field of marine injection devices, specifically an injection device for uniformly laying anti-erosion materials for offshore wind power. Background Technology

[0002] Offshore building foundations are easily eroded by sea currents, leading to the loss of sediment around the foundation and potentially affecting its stability. From a foundation consolidation technology perspective, erosion protection is necessary. Traditional erosion protection materials are pumped onto the construction vessel during construction. However, the pumping target area is around the subsea pile foundation, and the distance from the ship's deck to the seabed is typically tens of meters. As wind power expands into deeper waters, the water depth is increasing, further escalating the construction challenges. Current erosion protection material application processes usually involve mixing the materials on the construction vessel and then pumping them directly to the designated area. To ensure complete coverage of the foundation, the common method is for the construction vessel to move around the jacket structure on the sea surface, while the pumping pipe connected to the vessel rotates around the pile foundation for pouring. This method requires extensive movement of the construction vessel on the sea surface, consuming significant manpower and resources. Furthermore, the pumping pipes are subject to seawater fluctuations, making it difficult to control the uniformity of the erosion protection material. Utility Model Content

[0003] The purpose of this invention is to provide an injection device for uniformly laying anti-erosion materials for offshore wind power, so as to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grouting device for uniformly laying scour-resistant materials for offshore wind power, comprising a grouting device body and a steel pipe pile. The grouting device body is mounted on the steel pipe pile. The grouting device body includes an outer shell and an inner cavity. A fixed end is provided on the outer shell, and a chain lifting mechanism is connected to the fixed end. A grouting connection port penetrating the outer shell is provided on the inner cavity. An inclined step is provided on the side of the inner cavity near the steel pipe pile. The inclined step slopes upward along the direction of the steel pipe pile. A discharge port is also provided on the inner cavity above the inclined step.

[0005] Preferably, the chain lifting mechanism includes a chain take-up and release frame, rollers and a chain. The chain take-up and release frame is mounted on a steel pipe pile. The rollers are connected to the chain take-up and release frame via a support frame. A hook is provided at the bottom of the chain for fixing it to the fixed end of the outer shell. A rotating shaft is provided on the chain take-up and release frame.

[0006] Preferably, the inner cavity is configured as a ring-shaped structure, a connecting shaft is provided on one side of the inner cavity, and a locking mechanism is provided at the connection point on the other side of the inner cavity.

[0007] Preferably, the locking mechanism includes an upper locking plate and a lower locking plate, both of which are provided with through holes, and the upper locking plate and the lower locking plate are fixed together by bolts and through holes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a grouting device for uniformly laying scour-resistant materials for offshore wind power, comprising a grouting device body 1 and a steel pipe pile 2. The grouting device body 1 is mounted on the steel pipe pile 2. The grouting device body 1 includes an outer shell 3 and an inner cavity 4. A fixed end 5 is provided on the outer shell 3, and a chain lifting mechanism 6 is connected to the fixed end 5. A grouting connection port 7 is provided on the inner cavity 4 through the outer shell 3. An inclined step 8 is provided on the side of the inner cavity 4 near the steel pipe pile 2. The inclined step 8 is inclined upward along the direction of the steel pipe pile 2. A discharge port 9 is also provided on the inner cavity 4 above the inclined step 8.

[0024] Specifically, the chain lifting mechanism 6 includes a chain take-up and release frame 10, rollers 11, and a chain 12. The chain take-up and release frame 10 is mounted on the steel pipe pile 2. The rollers 11 are connected to the chain take-up and release frame 10 via a support frame 13. A hook 14 is provided at the bottom of the chain 12. The hook 14 is used to fix and connect to the fixed end 5 of the outer shell 3. A rotating shaft 15 is provided on the chain take-up and release frame 10. With the above configuration, the chain lifting mechanism 6 can realize the lifting and lowering of the injection device body 1. The chain lifting mechanism 6 rotates through the rotating shaft 15 on the chain take-up and release frame 10, which drives the chain 12 to roll, thereby realizing the up and down movement of the hook 14. The hook 14 is connected to the fixed end 5 of the outer shell 3. When the chain lifting mechanism 6 is working, the injection device body 1 rises or falls accordingly.

[0025] Specifically, the inner cavity 4 is configured as a ring-shaped structure. A connecting shaft 16 is provided on one side of the inner cavity 4, and a locking mechanism 17 is provided at the connection point on the other side of the inner cavity 4. Further, the locking mechanism 17 includes an upper locking plate 18 and a lower locking plate 19, both of which are provided with through holes 20. The upper locking plate 18 and the lower locking plate 19 are fixed together by bolts and the through holes 20. Furthermore, a sealing strip 21 is also provided at the connection point of the inner cavity 4. The above-mentioned configuration makes it easier for the inner cavity 4 to be fitted onto the steel pipe pile 2. Through the locking mechanism 17, the upper locking plate 18 and the lower locking plate 19 working together to lock the inner cavity 4, and the sealing strip 21 set at the connection of the inner cavity 4, the inner cavity 4 forms a good sealing effect, ensuring that the grouting material will not leak during the grouting process. Furthermore, the inner cavity 4 fits the steel pipe pile 2, allowing the grouting material to flow out along the wall of the steel pipe pile 2 and naturally settle into the target area, thereby making the grouting material more evenly grouted.

[0026] Specifically, the drive motor 22 is connected to the rotating shaft 15 via a coupling 23. By setting up the drive motor 22, it is easier to realize the lifting and lowering operation of the injection device body 1. The drive motor 22 is connected to the rotating shaft 15 via the coupling 23. When the motor is working, the rotating shaft 15 rotates, thereby driving the chain 12 of the chain lifting mechanism 6 to realize the lifting and lowering of the injection device body 1.

[0027] Specifically, a sealing ring 24 is provided at the connection between the outer shell 3 and the grouting connection port 7. By providing the sealing ring 24, the connection between the grouting connection port 7 and the outer shell 3 is made tighter, effectively preventing the leakage of grout during the grouting process.

[0028] A specific application example of this embodiment is as follows:

[0029] In use, the inner cavity 4 is connected to the steel pipe pile 2 via the connecting shaft 16. The upper locking plate 18 and lower locking plate 19 are then used to lock the connection, secured by two bolts. A sealing strip 21 is attached to the connection point of the inner cavity 4. After locking, the hook 14 on the chain 12 of the chain lifting mechanism 6 is installed on the fixed end 5 of the outer shell 3. The drive motor 22 is started for testing, causing the rotating shaft 15 to rotate, thereby driving the chain 12 of the chain lifting mechanism 6 to raise and lower the injection device body 1. When the lifting operation works normally, the injection device body 1 is adjusted to the water level. On the surface, the pumping pipeline on the ship is connected to the grouting connection port 7 for grouting. When the grouting operation is in progress, the drive motor 22 is started at the same time to lower the grouting device body 1 to the seabed pile foundation position of the steel pipe pile 2. At this time, after the anti-scour material (grouting material) enters the inner cavity 4, it will not flow out immediately. Instead, when the anti-scour material in the inner cavity 4 overflows to the discharge port 9, the anti-scour material in the entire inner cavity 4 will begin to flow out along the pipe pile wall and naturally sink to the target area. After the overall work is completed, the drive motor 22 is started to raise the grouting device body 1 to the water surface and the locking mechanism 17 is opened for recovery.
