Deep sea environment simulation device

Abstract

The invention discloses a deep sea environment simulation device. The deep sea environment simulation device comprises a main cylinder body, the upper end of the main cylinder body is connected with an upper head, the lower end of the main cylinder body is connected with a lower head, and the side of the main cylinder body is provided with a pressure drain port and a water pump drain port; the lower end of the main cylinder body is provided with a secondary cylinder body, the secondary cylinder body is connected with the lower head, the secondary cylinder body is provided with a drain pump, the diameter of the secondary cylinder body is smaller than the caliber of the main cylinder body, and a sub-head is connected to the lower end of the secondary cylinder body; the inside of the lower head is filled with a bracket body, and the bracket body is welded to the inner wall of the lower head; a pressure drain pipe is connected to the pressure drain port, and a pump power drain pipe is connected to the pump drain port; the pressure drain pipe and the pump power drain pipe extend through the bracket body to the inside of the secondary cylinder body, and the pump power drain pipe is connected to the drain pump; and the main cylinder body and the secondary cylinder body are buried below the ground, and a sand-concrete layer is attached to the outer side of the main cylinder body and the secondary cylinder body. The deep sea environment simulation device can simulate the deep sea water environment at a test site with the maximum matching degree, and the safety performance is reliable.

Description

technical field [0001] The invention relates to a deep-sea environment simulation device, which belongs to the technical field of deep-sea environment simulation. Background technique [0002] The deep sea usually refers to the water depth below 200 meters in the sea area. The deep sea is characterized by high pressure, slow bottom water flow, no light, low water temperature, high salinity, rich oxygen content, and many sediments. In the face of various needs such as energy and military strategy, deep sea development is becoming more and more attractive. Metal has become the most widely used structure in deep sea engineering because of its good strength. However, the corrosion of metal materials has brought great difficulties and losses to deep sea development, and more and more attention has been paid to the corrosion resistance of metal materials in deep sea environments. [0003] As the depth of sea water increases, the pressure of sea water also gradually increases. P...
