Description

Technical Field

[0001] This utility model belongs to the technical field of offshore wind power foundation construction equipment, specifically relating to an anti-segregation conveying pipeline assembly for offshore wind power grouting material. Background Technology

[0002] In the grouting construction of offshore wind power foundations, grout needs to be transported from the construction platform to the underwater grouting area via pipelines. Due to the continuous wind and wave vibrations in the offshore environment, traditional grouting delivery pipelines have the following problems: First, the grout is prone to aggregate settling and grout segregation within the pipeline due to vibration, resulting in uneven grout strength; second, pipe bends are prone to blockage due to poor grout flow, and traditional unblocking methods require disassembling the pipeline, which is cumbersome and affects the continuity of construction; third, the lack of real-time monitoring means it is difficult to provide early warning of segregation or blockage risks, which can easily lead to hidden construction quality problems. Therefore, it is necessary to develop a grouting delivery pipeline assembly that is adapted to the offshore environment, is anti-segregation, and easy to unblock. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a marine wind power grouting material anti-segregation conveying pipeline assembly to solve the technical problems of easy segregation of grouting material, difficulty in clearing blockages, and lack of early warning mechanism.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: A segregation-preventing conveying pipeline assembly for offshore wind power grouting includes an anti-segregation conveying pipe group, a vibration monitoring module, and a grout unblocking module. The anti-segregation conveying pipe group includes a grouting pipe and a feeding and mixing assembly. The feeding and mixing assembly is located at the inlet of the grouting pipe and is used to mix the input grouting material.

[0005] The vibration monitoring module includes a vibration sensor and a pressure sensor. The vibration sensor is used to monitor the vibration frequency of the grouting pipe in real time. The pressure sensor is used to monitor the pressure fluctuations of the grouting material inside the grouting pipe in real time.

[0006] The slurry unblocking module includes a sealing cap, a retractable unblocking tube, a rotating brush head, and a cap connecting assembly. A cleaning port is provided on the grouting pipe. The sealing cap is detachably fixed to the unblocking port via the cap connecting assembly. The retractable unblocking tube is installed inside the unblocking port. The rotating brush head is rotatably connected to the retractable unblocking tube.

[0007] Furthermore, the feeding and mixing assembly includes a rotating rotor and multiple helical guide vanes. The rotating rotor is fixed to the inlet end of the grouting pipe by a bracket. Each helical guide vane is connected to the power output end of the rotating rotor and is evenly distributed circumferentially along the axis of the grouting pipe.

[0008] Furthermore, the outer ring of the grouting pipe is provided with multiple annular stiffening ribs. Each annular stiffening rib is arranged at intervals along the length of the grouting pipe and is welded and fixed to the outer wall of the grouting pipe.

[0009] Furthermore, the grouting pipe adopts a double-layer structure, with the outer layer being a wear-resistant stainless steel pipe and the inner layer being a polytetrafluoroethylene non-stick lining.

[0010] Furthermore, the anti-separation delivery pipe assembly also includes a large-curvature elbow. The grouting pipeline is divided into horizontal and vertical pipes. The horizontal and vertical pipes are connected by a large-curvature elbow. The radius of curvature R of the large-curvature elbow is greater than or equal to three times the diameter D of the grouting pipeline.

[0011] Furthermore, the radius of curvature R of the large curvature elbow is 5 to 10 times the diameter D of the grouting pipe.

[0012] Furthermore, multiple vibration sensors are provided, and each vibration sensor is arranged at intervals along the length of the grouting pipe.

[0013] Furthermore, in the initial state, the retractable unblocking tube is embedded inside the sealing cap.

[0014] Furthermore, the sealing cap assembly includes a flange and multiple bolts. The flange is fixed to the outer ring of the sealing cap. The flange is detachably fixed to the grouting pipe by the bolts.

[0015] Furthermore, a rubber seal is provided between the sealing cap and the unblocking port.

[0016] Compared with the prior art, the present invention has the following advantages: 1. Significant anti-segregation effect: This utility model is equipped with a feeding and mixing component at the input end of the grouting pipe. The rotating rotor in the feeding and mixing component drives the spiral guide vanes to rotate. Combined with the large curvature elbow design, it can effectively slow down the aggregate sedimentation and segregation of the grouting material during the transportation process, ensuring the homogeneity of the grouting material. The double-layer pipe structure reduces grout adhesion and further reduces the risk of segregation.

[0017] 2. Timely pipe blockage warning: This utility model monitors the pipe status in real time by installing vibration and pressure sensors on the grouting pipe. When an abnormal state occurs in the grouting pipe during the grouting process, an audible and visual alarm will be triggered, which facilitates early intervention by construction personnel and reduces the probability of pipe blockage.

[0018] 3. Convenient unblocking operation: This utility model uses a retractable unblocking tube and a rotating brush head at the unblocking port, and the sealing cover is fastened with a flange and bolts. Unblocking can be completed without disassembling the pipeline, ensuring the sealing of the pipeline before and after unblocking and improving the continuity of construction.

[0019] 4. Excellent vibration resistance: This utility model enhances the overall rigidity of the grouting pipe by setting annular stiffening ribs on the outer ring, which can adapt to the vibration environment of wind and waves at sea and extend the service life of the pipe.

Therefore, they should not be construed as limitations on this utility model.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1 and 2 As shown, an anti-segregation conveying pipeline assembly for offshore wind power grouting includes an anti-segregation conveying pipe group, a vibration monitoring module 2, and a grout unblocking module 31. The anti-segregation conveying pipe group includes a grouting pipe 11 and a feeding and mixing assembly. The feeding and mixing assembly is located at the inlet of the grouting pipe 11 and is used to mix the input grouting material, thereby mitigating aggregate settling in the grouting material through shearing and diversion.

[0025] The vibration monitoring module 2 is used to monitor the vibration frequency of the grouting pipe 11 and the pressure fluctuation of the grouting material inside the grouting pipe 11.

[0026] The grouting pipe 11 is provided with a cleaning port that cooperates with the grout unblocking module 31, which is used to perform unblocking operations when grouting blockage occurs in the grouting pipe 11.

[0027] Specifically, such as Figure 1 As shown, the feeding and mixing assembly includes a rotating rotor 13 and multiple spiral guide vanes 12. The rotating rotor 13 is fixed to the input end of the grouting pipe 11 by a bracket. Each spiral guide vane 12 is connected to the power output end of the rotating rotor 13 and is evenly distributed circumferentially along the axis of the grouting pipe 11. The rotating rotor 13 drives each spiral guide vane 12 to rotate, shearing and mixing the grout material input into the grouting pipe 11, thus slowing down the settling of aggregates in the grout material.

[0028] Furthermore, the outer ring of the grouting pipe 11 is provided with multiple annular stiffening ribs 15. Each annular stiffening rib 15 is arranged at intervals along the length of the grouting pipe 11 and is welded and fixed to the outer wall of the grouting pipe 11 to increase the vibration resistance of the grouting pipe 11 and reduce the impact of wind and wave vibration on the grouting pipe 11.

[0029] In this embodiment, the grouting pipe 11 adopts a double-layer structure, with the outer layer being a wear-resistant stainless steel pipe and the inner layer being a polytetrafluoroethylene non-stick lining.

[0030] Furthermore, the anti-separation conveying pipe assembly also includes a large-curvature elbow 14. The grouting pipe 11 is divided into horizontal and vertical pipes. The horizontal and vertical pipes are connected by the large-curvature elbow 14. The radius of curvature R of the large-curvature elbow 14 is greater than or equal to three times the diameter D of the grouting pipe 11, preferably five to ten times the diameter D of the grouting pipe 11. The selection is based on specific project requirements.

[0031] In some embodiments, the rotating rotor includes a mounting housing, a drive motor, and a rotating connector. The mounting housing is fixed to the inlet end of the grouting pipe by a bracket. The rotating connector is rotatably connected to the inner end of the mounting housing. The inner ends of each helical guide vane are fixed to the rotating connector. The drive motor is disposed within the mounting housing, and its power output shaft is connected to the rotating connector. The drive motor rotates via the rotating connector, thereby driving each helical guide vane to rotate axially around the grouting pipe.

[0032] like Figure 1 As shown, the vibration monitoring module 2 includes a vibration sensor 21 and a pressure sensor 22. The vibration sensor 21 is mounted on the outer wall of the grouting pipe 11. Multiple vibration sensors 21 are arranged at intervals along the length of the grouting pipe 11, enabling real-time monitoring of the vibration frequency of the grouting pipe 11. The pressure sensor 22 is fixed on the inner wall of the grouting pipe 11 and is used to monitor the pressure fluctuations of the grouting material inside the grouting pipe 11 in real time.

[0033] In this embodiment, both vibration sensor 21 and pressure sensor 22 are connected to the construction platform control console via a wireless module. When an abnormal vibration frequency or a sudden increase in pressure is detected, the control console triggers an audible and visual alarm to indicate the risk of segregation or potential pipe blockage.

[0034] like Figure 2 As shown, the slurry unblocking module 31 includes a sealing cap 34, a retractable unblocking tube 32, a rotating brush head 33, and a cap connecting assembly. The sealing cap 34 is detachably fixed to the unblocking port via the cap connecting assembly. The retractable unblocking tube 32 is installed at the unblocking port. In the initial state, the retractable unblocking tube 32 is embedded within the sealing cap 34. Two rotating brush heads 33 are rotatably connected to both ends of the retractable unblocking tube 32. The retractable tube is manually extended. The rotating brush heads 33 clear blockages within the grouting pipe 11.

[0035] In this embodiment, the cleaning port is located on the side wall of the large curvature elbow 14. The sealing connection assembly includes a flange 35 and multiple bolts 36. The flange 35 is welded and fixed to the outer ring of the sealing cover 34. The flange 35 is detachably fixed to the grouting pipe 11 by the bolts 36, which can close the cleaning port during grouting and open the cleaning port when blocked. A rubber seal is provided between the sealing cover 34 and the cleaning port to ensure that the high-pressure grout in the grouting pipe 11 does not leak during the grouting process.

[0036] The working principle of this utility model is as follows: like Figure 3 As shown, during construction, the grout enters from the input end of the grouting pipe 11, and the rotating rotor 13 drives each spiral guide vane 12 to rotate, shearing and diverting the grout. At the same time, the vibration sensor 21 and the pressure sensor 22 monitor the pipe status in real time, and the data is transmitted to the control console.

[0037] When a blockage occurs in the grouting pipe 11, the pressure sensor 22 detects a sudden increase in pressure and triggers an alarm. The operator shuts off the grouting pump, loosens the bolt 36 to open the sealing cover 34, and cleans the blockage using the retractable unblocking pipe 32 and the rotating brush head 33. After the blockage is cleared, the sealing cover 34 is closed and the bolt 36 is tightened, and the grouting operation is restarted.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
