Problems solved by technology

[0005] The jack-up platform uses pile legs to go up and down, and the pile legs need to use the spud shoes at the bottom of the pile legs to contact the seabed after they go deep into the seabed. Since the seabed sediment has a certain thickness and the operation of the offshore platform takes a certain amount of time, the spud shoes will Caught in the sediment, this situation causes the platform to require more force when pulling out the piles, which will cause greater vibration when pulling out the piles

Embodiment 1

[0043] Additionally, combined with Figure 1-3 and Figure 6 As shown, the check valve 400 includes a valve seat 410 and a diaphragm 420, the diaphragm 420 is installed on the valve seat 410, and the valve seat 410 is fixedly installed on the water inlet pipe 130; the valve seat 410 It includes a circular bottom frame 411 and a side wall 412 surrounding the edge of the circular bottom frame 411, the side wall 412 is facing the water outlet, the middle part of the circular bottom frame 411 is a round hole, and the upper cover A hemispherical frame 430 is provided, and the hemispherical frame 430 protrudes toward the water outlet, and the center of the diaphragm 420 is fixedly connected to the top of the hemispherical frame 430 . The concave surface of the hemispherical frame 430 of the check valve 400 is the water inlet, so that the water flow will easily pass the diaphragm 420 set on the hemispherical frame 430 through the check valve 400, and when spraying water, the water p...

Embodiment 2

[0046] In addition, if Figure 1-2 as well as Figure 4-5 As shown, the dispersion nozzle 500 includes a nozzle body 510, one end of the nozzle body 510 is the water inlet end, and the other end is the water outlet end, and the water outlet end is also provided with a water outlet cover 520, and the water outlet cover 520 is distributed There are several water outlet holes 530; the water outlet holes 530 are variable diameter holes, the diameter of the inner end is larger than the diameter of the outer end; the water outlet cover 520 is fixedly connected with the nozzle body 510 by threads. The function of the dispersing nozzle 500 is to expand the water spraying area, so that a larger area of ​​soil can be sprayed through a plurality of water outlet holes 530, which improves the speed and efficiency of impacting the soil, and the variable diameter design of the water outlet holes can also increase the water pressure. The impact force of water is greater, and blockage can als...

Abstract

The invention relates to the field of ocean platforms, in particular to a pile shoe with the function of eliminating submarine attachments. The pile shoe comprises a spray head, a water source pipeline and an air source pipeline. The water source pipeline and the air source pipeline are both connected to the spray head. The spray head comprises a pressurization cavity, a spray pipe, a water inlet pipe, an air inlet pipe and a non-return valve. The pressurization cavity comprises a bottom cover, a barrel body and an upper cover. The bottom cover and the upper cover are fixed to the two ends of the barrel body. The spray pipe is vertically arranged at the center of the barrel body and is arranged and fixed to the upper cover in a penetrating mode. A water inlet of the spray pipe faces towards the bottom cover. The water inlet pipe and the air inlet pipe are fixedly arranged on the barrel body. The water inlet pipe is located on the lower portion of the barrel body. The air inlet pipe is located at the upper end of the barrel body. The water inlet pipe is provided with the non-return valve. The pile shoe comprises a pile shoe part and a pile leg base fixed to the pile shoe part. The vertical view of the pile shoe part is octagonal. The pile leg base is fixed to the center of the pile shoe part. According to the pile shoe with the function of eliminating the submarine attachments, the pile shoe of an ocean platform has a water spray function and can be pulled out more easily; and the pile shoe is provided with the excellent non-return device.

Description

technical field [0001] The invention relates to the field of offshore platforms, in particular to a spud can with the function of eliminating seabed attachments. Background technique [0002] The offshore platform is a structure that provides production and living facilities for activities such as drilling, oil production, transportation, observation, navigation, and construction at sea. [0003] According to its structural characteristics and working status, it can be divided into two types: fixed type and movable type. The lower part of the fixed platform is directly supported by piles, expanded footings or other structures and is fixed to the seabed. According to the support situation, it is divided into two types: pile foundation type and gravity type. The movable platform is floating in the water or supported on the seabed, and can be displaced from one well to another. The supporting conditions can be divided into bottom type and floating type. In recent years, a nov...
