Description

Technical Field

[0001] The utility model relates to the foundation construction of an offshore wind turbine, in particular to an air inflation device for a sinking prevention plate of a submersible platform. Background Art

[0002] At present, submersible auxiliary construction platforms are widely used in the foundation construction of offshore wind power projects. Such construction platforms usually have large-area sinking prevention plates at the lower part to maintain the stability of sitting on the bottom and prevent uneven settlement of the construction platform. In the construction sea area with a deep overburden layer, the silty soil layer will generate a large adsorption force on the sinking prevention plate of the construction platform, resulting in difficult mud discharge of the sinking prevention plate when the whole construction platform is lifted and transferred. The commonly used existing solution is to use divers to carry high-pressure water guns for underwater mud flushing. This scheme cannot disturb the silt at the bottom of the sinking prevention plate and has limited effect on weakening the adsorption force. Therefore, it is very valuable to invent a device that can quickly, simply and effectively reduce the adsorption force of the soil layer on the sinking prevention plate. Summary of the Invention

[0003] The purpose of the utility model is to provide an air inflation device for a sinking prevention plate of a submersible platform, which can realize the exhaust of the sinking prevention plate, quickly, simply and effectively reduce the adsorption force of the soil layer on the sinking prevention plate, ensure the smooth floating of the sinking prevention plate and the integrity of the structure, and can meet the requirements for reuse.

[0004] The purpose of the utility model is realized as follows:

[0005] An air inflation device for a sinking prevention plate of a submersible platform, characterized in that: it includes an air compressor joint, a main air inflation steel pipe, branch air inflation steel pipes, connectors, an air compressor and an air outlet hose. A platform column perpendicular to the sinking prevention plate and with its bottom passing through the sinking prevention plate is provided in the middle of the sinking prevention plate. Three exhaust holes penetrating the plate body of the sinking prevention plate are evenly arranged around the platform column on the sinking prevention plate. An air inlet of the sinking prevention plate is provided at the upper end of the exhaust hole on the upper panel of the sinking prevention plate, and the diameter of each air inlet of the sinking prevention plate is adapted to the diameter of the branch air inflation steel pipe; an air compressor joint of the main air inflation steel pipe is provided on a cross beam on the side wall at the top end of the platform column, and the air compressor is connected to the air compressor joint of the main air inflation steel pipe through the air outlet hose; the main air inflation steel pipe is parallel to the platform column. Two connectors are provided at the lower end of the main air inflation steel pipe. The air inlets of three "L"-shaped branch air inflation steel pipes are respectively connected to the main air inflation steel pipe through the lower end and the bottom connector of the main air inflation steel pipe, and the air outlets of the three branch air inflation steel pipes are connected to the air inlets of the sinking prevention plate. The main air inflation steel pipe and the three branch air inflation steel pipes form a whole; the air compressor is connected to the air compressor joint at the top end of the main air inflation steel pipe through the air outlet hose.

[0006] A vertical and horizontal fixing plate perpendicular to the platform column is provided in the middle of the side wall of the platform column, and the other end of the fixing plate is used to fix the middle part of the main air inflation steel pipe.

[0007] According to the usage of the engineering construction platform, the anti-settlement plate is embedded in the silt stratum, and the overall lifting weight of the construction platform has increased significantly compared to its own weight. Therefore, when the construction platform is fabricated in the early stage, the present utility model is designed at the anti-settlement plate part to achieve the smooth mud discharge of the anti-settlement plate.

The main inflatable steel pipe and the branch inflatable steel pipes are combined through the connecting piece. The air outlets of the three branch inflatable steel pipes are connected to the air inlets of the anti-settlement plate.

[0009] The working principle is as follows: The diver goes underwater and installs the air outlet hose of the air compressor onto the air compressor joint at the top end of the main inflatable steel pipe. Then, the air compressor is started, so that the compressed air enters from the air inlet of the anti-settlement plate and is ejected from the exhaust holes of the air inlet of the anti-settlement plate body of the anti-settlement plate, that is, the compressed air is quickly conveyed to the bottom of the anti-settlement plate through the inflating device by using the air compressor, thereby dispersing the soil layer at the bottom of the anti-settlement plate body, separating the silt from the anti-settlement plate, and quickly, simply and effectively reducing the adsorption force of the soil layer on the anti-settlement plate, so that the platform can be smoothly lifted out of the water.

[0010] The present utility model has the following advantages:

[0011] 1. It can realize the exhaust of the anti-settlement plate, quickly, simply and effectively reduce the adsorption force of the soil layer at the bottom of the anti-settlement plate body on the anti-settlement plate, and reduce the lifting weight and hoisting risk of the submersible platform;
