The deepest part of the ocean can reach 1100 atmospheres, and deep sea equipment has to face the situation of high pressure in the deep sea. When some special equipment needs to take water from the seawater, the flow pipeline will be exposed to seawater impact caused by huge pressure difference. In general, the design scheme needs to be designed according to the maximum seawater depth, and the deep seawater pressure is resisted by methods of strengthening the structure, increasing the flow resistance and the like.
However, such designs often result in complex structures, heavy size, increased mass, and the like.

According to the theory of fluid mechanics, the flow rate of the pipeline is positively correlated with the pressure difference between the inlet and the outlet and the interception area. The working principle of the invention is as follows: when the pressure difference between the water inlet and the water outlet is increased, the flow-stopping area is reduced by using the resistance generated by the flow of the fluid; the increased pressure difference of the water inlet and the water outlet and the decreased throttling area are mutually offset, so that the flow can be relatively stable.

Detailed Description
The invention is further described with reference to the following figures and embodiments.
Referring to fig. 1 to 4, the full-sea-depth self-adaptive pipeline disclosed by the invention is suitable for a steady flow design under the condition of a large pressure difference between an inlet and an outlet of a flow channel, and comprises a pipe body, wherein a fixed impeller 5 fixedly connected with deep-sea equipment and a middle shaft 3 fixedly connected with the fixed impeller 5 are respectively fixed in the pipe body, an movable impeller 2 is sleeved on the middle shaft 3, a limit nut 1 for limiting the movable impeller 2 is arranged at the top of the middle shaft 3, a spiral groove is arranged on the outer wall surface of the middle shaft 3, the movable impeller 2 axially moves on the middle shaft 3 through the spiral groove and simultaneously rotates, a spring 4 is arranged between the movable impeller 2 and the fixed impeller 5, the movable impeller 2 and the fixed impeller 5 have the same projection along the axial direction of the middle shaft 3, and the movable impeller 2 is separated from the fixed impeller 5 under the action of the spring 4 and is limited by the limit nut 1. When the seawater depth work is maximized, the movable impeller 2 and the fixed impeller 5 are closest to each other, and the projection area along the axial direction of the middle shaft 3 is maximized. The upper surfaces of the movable impeller 2 and the fixed impeller 5 are inclined cambered surfaces, the lower surfaces of the movable impeller and the fixed impeller are planes, and the inclined directions of the upper surfaces of the impellers are consistent.
Referring to fig. 5, the deep sea equipment disclosed by the invention comprises a low-pressure water containing cavity, a water inlet and outlet flow channel communicated with the low-pressure water containing cavity and a valve arranged at an inlet of the low-pressure water containing cavity in the flow channel, wherein a full-sea-depth self-adaptive pipeline is arranged at the inlet of the flow channel, so that in order to improve the pressure resistance index, a pipe body and a deep sea equipment shell can be integrally formed, and the water inlet and outlet flow channel is directly used as the pipe body. Preferably, the flow channel has a plurality of 90 ° bends, and further includes a first flow channel perpendicular to the pipe body and a second flow channel perpendicular to the first flow channel, and the valve is located in the second flow channel.
The working process of the present invention is further described below with reference to fig. 6: when the full-sea-depth self-adaptive pipeline is not equipped and other control measures are not taken, the relation between the flow rate of the seawater entering the low-pressure water containing cavity and the depth of the seawater is shown in fig. 6. The inflow of water will rise sharply with the depth of seawater, and the impact force will have great influence on the structure of the pipeline, valve and water chamber.
After the full-sea-depth self-adaptive pipeline is equipped, in a shallow sea area, because the pipeline can generate extra flow resistance, the flow of a deep-sea equipment flow channel is slightly smaller than that under the condition of no equipment.
As the depth of the seawater increases, the flow resistance pushes the impeller 2 to rotate, so that the flow area of the seawater decreases, and the flow rate is slightly larger than that of the shallow sea area. With the further increase of the depth of the seawater, the distance between the movable impeller 2 and the fixed impeller 5 is further reduced, the flow area is smaller, and the flow rate tends to be reduced at the moment. When the seawater depth reaches the maximum design depth, the distance between the movable impeller 2 and the fixed impeller 5 is the shortest, the flow area is the smallest, and the flow is equal to that in the shallow sea area by designing the appropriate flow area.
Under the condition of the same structure of other parts, the flow can be reduced after the device is equipped in a shallow sea area, and the problem can be solved by properly enlarging the pipe diameter.
The invention can also be applied to non-underwater equipment systems with large inlet and outlet pressure difference change. Its function is to maintain its throughput at a relatively constant level when the inlet is in direct contact with seawater and the outlet is at atmospheric or other lower pressure.
The above-described embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments may be applied, and it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the inventive concept of the present invention, and these embodiments are within the scope of the present invention.
