Description

Technical Field

[0001] This utility model relates to the technical field of underwater exploration, and more specifically, it relates to a pressure-resistant chamber. Background Technology

[0002] As a crucial piece of equipment in deep-sea operations, deep-sea pressure tanks require high levels of sealing and strength. Most existing pressure tanks employ threaded connections and sealing rings for their sealing structures. However, in the high-pressure environment of the deep sea, the increased water pressure can damage the sidewalls of the pressure tank, reducing the internal space. Consequently, during the lifting process, the reduced water pressure and the resulting decrease in internal space can cause the internal pressure to exceed the external water pressure, thus affecting the sealing of the pressure tank's end caps. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pressure-resistant tank. Through the configuration of a pressure-transforming chamber and a piston in the oil pipe within the tank, in deep-sea areas, hydraulic oil in the oil pipe enters the pressure-transforming chamber to increase the pressure within the chamber, thereby preventing water pressure from damaging the tank body. When entering shallow-sea areas, excess hydraulic oil in the pressure-transforming chamber enters the oil pipe to balance the pressure difference between the pressure-transforming chamber and the seawater, thus reducing the likelihood of tank body damage and end cap seal failure.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pressure-resistant chamber, comprising a chamber body, wherein the chamber body is configured as a circular tube with open ends, and a pressure-transforming cavity is provided in the side wall of the chamber body and arranged around the axis of the chamber body, the pressure-transforming cavity being filled with hydraulic oil;

[0005] The end caps are provided with two detachable end caps that are connected to both ends of the chamber to achieve sealing of both ends of the chamber. The two end caps are respectively set as a fixed end cap and a balanced end cap. The balanced end caps are provided with several through holes that communicate with the transformer chamber. The several through holes are arranged around the axis of the chamber.

[0006] Oil pipe, which is fixedly connected to the end of the balance end cover away from the tank body, and several through holes on the balance end cover are connected to the inner cavity of the oil pipe;

[0007] And a piston plate, the oil pipe is provided with a piston plate coaxial with the oil pipe, and the oil pipe is also filled with hydraulic oil on the side of the piston plate near the balance end cap.

[0008] The present invention is further configured such that: the part of the end cap inserted into the chamber body is a sealing part, and an annular sealing groove is provided outside the sealing part; multiple sealing grooves are provided and arranged along the axial direction of the end cap.

[0009] A sealing gasket is provided inside the sealing groove.

[0010] The present invention is further configured such that: a flat plate is connected to one end of the fixed end cap that extends into the chamber body, and the electrical components inside the pressure chamber are mounted on the flat plate.

[0011] The present invention is further configured such that: the flat plate is parallel to the axis of the silo body, and a mounting plate perpendicular to the flat plate is fixedly connected to one end of the flat plate near the fixed end cover, and the mounting plate is detachably connected to the fixed end cover by bolts.

[0012] The present invention is further configured such that: the fixed end cap is provided with a clearance hole for the cable to pass through, and a sealing plug is provided in the clearance hole to close the clearance hole.

[0013] The present invention is further configured such that the end cap is detachably connected to the chamber body by a plurality of bolts arranged around the axis of the end cap.

[0014] The present invention is further configured such that: a fixing plate is fixedly connected to one end of the oil pipe away from the balance end cap, and the fixing plate is provided with a plurality of balance holes surrounding the axis of the oil pipe, the balance holes penetrating the fixing plate;

[0015] The fixed plate is provided with a guide rod that passes through the fixed plate along the axis of the oil pipe. The length direction of the guide rod is along the axis of the oil pipe, and one end of the guide rod near the piston plate is fixedly connected to the piston plate. The guide rod can slide on the fixed plate along its own length direction.

[0016] In summary, this utility model has the following advantages compared to the prior art: By setting up a pressure-transforming chamber inside the tank and a piston inside the oil pipe, the hydraulic oil in the oil pipe will enter the pressure-transforming chamber in deep sea areas to increase the pressure inside the pressure-transforming chamber and thus prevent water pressure from damaging the tank. When entering shallow sea areas, the excess hydraulic oil in the pressure-transforming chamber will enter the oil pipe to balance the pressure difference between the pressure-transforming chamber and the seawater, thus making it less likely for the tank to be damaged or for the end cap to fail to seal.
