Description

Offshore wind power jacket feeding structure and grouting operation device Technical Field The application belongs to the technical field of grouting operation devices, and particularly relates to a feeding structure of an offshore wind power jacket and a grouting operation device. Background The grouting operation device for the offshore wind power jacket is special equipment for grouting slurry into a gap between the jacket and a pile foundation in the installation process of the offshore wind power jacket. The grouting device has the core functions of injecting grouting materials into the gap in a pumping mode and the like to form firm connection, so that the overall stability of the jacket foundation is ensured. The device generally comprises a grouting pump, a stirring system, a conveying pipeline, a control system and the like. Because of the need of adapting to complex offshore operation environment, the device has the characteristics of high automation, strong corrosion resistance and the like so as to ensure the accuracy and reliability of grouting operation. The grouting operation device in the prior art generally comprises a supporting platform, and a stirring system, a water supply system, a control system and a grouting system for grouting, which are arranged on the supporting platform. During operation, a crawler crane or a crane is generally adopted to hoist the grouting material ton bag above a dustproof barrel at the top of the stirrer, the bag breaker in the dustproof barrel is used for opening the bag, so that materials fall into the stirrer, then the waste bag is manually taken out, and the operations of water supply, stirring and discharging are completed through a control system. The technology related to the application is applied to an offshore operation environment. The offshore construction window period has larger uncertainty, and the offshore construction safety control is increasingly strict in the limitation of hoisting operation, so that the offshore grouting operation is further restricted. Particularly, the construction ship is easy to shake due to the influence of water flow and sea wind, particularly, in the ton bag breaking process, the crane shake is more obvious, and the safety risk of operators is increased. The existing bag breaking mode relies on that a material bag falls to a bag breaker at a specified position by self weight, and the material bag body is pierced by the bag breaker to enable the material to be scattered. In actual use, the effect of cracking is poor due to the deviation of the falling position of part of the material bags, the opening is smaller, and the material discharge is slow. Even after the bag is broken normally, the initial split is difficult to expand further, so that the blanking speed is limited, and a worker is often required to manually assist in shaking or adjusting to improve the blanking efficiency, so that the whole grouting operation device is inconvenient to operate. Therefore, there is a need to develop a feeding structure with low lifting requirements, so as to overcome the safety problem caused by feeding of the existing crane, improve the breaking structure, realize continuous and stable supply of materials, and further reduce the adverse effect of the complex working condition on the sea on the construction. Disclosure of Invention Aiming at the defects or shortcomings of the prior art, the application aims to provide a marine wind power jacket breaking structure and a grouting operation device.
