Description

Technical Field

[0001] The utility model relates to the technical field of submersibles, in particular to a water tank structure of a submersible. Background Art

[0002] The existing Titan submersible's water tank structure uses carbon fiber composite materials. Although this material is light and strong, it is prone to sudden collapse in the high-pressure environment of the deep sea, leading to implosion accidents.

[0003] The maintenance costs of existing submersible tank structures are generally high, especially for submersibles that utilize new technologies and materials. Maintenance and overhaul are more difficult and costly. Since submersibles often operate in deep-sea environments, overhauls often need to be performed underwater, which increases both the difficulty and the risks of overhauls.

[0004] The existing submersible water tank structure generally adopts flat plate cover for sealing. From the perspective of stress analysis, the stress condition of the flat plate seal is relatively simple, and it mainly bears the pressure perpendicular to the plate. When the flat plate seal is under pressure, the flat plate seal may face a greater risk of deformation, especially when the pressure is high. Utility Model Content

[0005] The purpose of the utility model is to provide a submersible water tank structure to solve at least one of the above problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A submersible water tank structure comprises a left water tank, a right water tank and a rear water tank, wherein the left water tank is arranged on the left side of the submersible, the right water tank is arranged on the right side of the submersible, and the rear water tank is arranged at the rear of the submersible, and water stop valve assemblies are provided on the left water tank, the right water tank and the rear water tank;

[0008] The left water tank, the right water tank and the rear water tank are all made of stainless steel 304 material, and both ends of the left water tank, the right water tank and the rear water tank are welded with arc-shaped end covers using a ring seam sealing welding process.

[0009] In this technical solution, the left water tank is located on the left side of the submersible and is used to store water or gas to help maintain the balance and stability of the submersible. The right water tank is located on the right side of the submersible, corresponding to the left water tank. The rear water tank is located at the rear of the submersible and is also used to store water or gas. In the submersible, the rear water tank is also used to control the diving and surfacing of the submersible. The left water tank, the right water tank and the rear water tank are provided with a water stop valve assembly to control the inflow and outflow of water or gas. The left water tank, the right water tank and the rear water tank are all made of stainless steel 304 material, and both ends of the left water tank, the right water tank and the rear water tank are welded with arc-shaped end covers using a circumferential seam sealing welding process to ensure the sealing and compressive strength of the welding. The arc-shaped end covers can better disperse the pressure and reduce local stress concentration. When under pressure, the arc-shaped end covers can more effectively resist deformation and maintain the stability of the structure to ensure that they meet the pressure resistance requirements. In addition, through the selection of arc-shaped end covers and stainless steel 304 materials, the arc-shaped end cover seal has a higher pressure-bearing capacity than the flat plate seal. Therefore, the arc-shaped end cover uses lighter materials than the flat plate under the same pressure, achieving higher pressure resistance and lighter weight, and improving the safety and stability of the submersible in deep-sea environments.

[0010] Furthermore, a propeller installation room is provided in the middle of the left water tank and the right water tank, and a propeller is provided in the propeller installation room.

[0011] Specifically, a part of the middle part of the left water tank and the right water tank is hollowed out to reserve a position for the thruster installation room. There is no need to let water in or out of the water tank. Only the thrusters are used to make the submersible dive up and down. In this way, in an emergency, if the water in the water tank cannot be discharged or if the submersible suddenly dives due to a sea water fault, the thrusters in the water tank can also be used to float up.

[0012] Furthermore, water level sensors are provided in the left water tank, the right water tank and the rear water tank, and the tops of the left water tank, the right water tank and the rear water tank are connected with air pipes, and the air pipes are provided with normally closed solenoid valves.

[0013] The water level sensor is used to detect the water level inside the left water tank, right water tank and rear water tank, and timely monitor and control the water volume. The normally closed solenoid valve controls the gas inlet and outlet, and the gas source provides 0.8 MPa high-pressure gas for discharging tank water.

[0014] Furthermore, in order to facilitate the installation of the water level sensor and the air pipe, the water level sensor is installed in the left water tank, the right water tank and the rear water tank through the docking joint, and the air pipe is connected to the stainless steel inner thread head provided on the left water tank, the right water tank and the rear water tank.

[0015] Furthermore, in order to facilitate the installation of the water stop valve assembly, the water stop valve assembly is installed on the arc-shaped end cover through the water stop valve connector and the supporting structure.

[0016] Furthermore, in order to be installed and matched with other components of the submersible, the left water tank and the right water tank also include closed baffles, which are welded between the front arc-shaped end cover and the inner side of the water tank pipe using a ring seam sealing welding process.

[0017] Furthermore, in order to improve the structural strength of the left water tank and the right water tank, an internal annular support plate and a T-shaped support plate are provided in the left water tank and the right water tank. There are two internal annular support plates in the water tank and they are arranged at intervals.

[0018] The beneficial effects of the present utility model are as follows: In this technical solution, the left water tank is located on the left side of the submersible and is used to store water or gas to help maintain the balance and stability of the submersible. The right water tank is located on the right side of the submersible, corresponding to the left water tank. The rear water tank is located at the rear of the submersible and is also used to store water or gas. In the submersible, the rear water tank is also used to control the diving and surfacing of the submersible. A water stop valve assembly is provided on the left water tank, the right water tank and the rear water tank to control the inflow and outflow of water or gas. The left water tank, the right water tank and the rear water tank are all made of stainless steel 304 material, and both ends of the left water tank, the right water tank and the rear water tank are welded with arc-shaped end covers using a circumferential seam sealing welding process, which ensures the sealing and compressive strength of the welding, and the arc-shaped end covers can better disperse the pressure and reduce local stress concentration. When under pressure, the arc-shaped end covers can more effectively resist deformation and maintain the stability of the structure to ensure that they meet the pressure resistance requirements. In addition, through the selection of arc-shaped end covers and stainless steel 304 materials, the arc-shaped end cover seal has a higher pressure-bearing capacity than the flat plate seal. Therefore, the arc-shaped end cover uses lighter materials than the flat plate under the same pressure, achieving higher pressure resistance and lighter weight, and improving the safety and stability of the submersible in deep-sea environments.

Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0025] Example 1:

[0026] like Figure 1-Figure 4 As shown, this embodiment provides a submersible water tank structure, including a left water tank 1, a right water tank 2 and a rear water tank 3. The left water tank 1 is arranged on the left side of the submersible, the right water tank 2 is arranged on the right side of the submersible, and the rear water tank 3 is arranged at the rear of the submersible. A water stop valve assembly 4 is provided on the left water tank 1, the right water tank 2 and the rear water tank 3;

[0027] The left water tank 1 , the right water tank 2 and the rear water tank 3 are all made of stainless steel 304 material, and both ends of the left water tank 1 , the right water tank 2 and the rear water tank 3 are welded with arc-shaped end covers 5 using a circumferential seam sealing welding process.

[0028] In this technical solution, the left water tank 1 is located on the left side of the submersible and is used to store water or gas to help maintain the balance and stability of the submersible. The right water tank 2 is located on the right side of the submersible, corresponding to the left water tank 1. The rear water tank 3 is located at the rear of the submersible and is also used to store water or gas. In the submersible, the rear water tank 3 is also used to control the diving and surfacing of the submersible. A water stop valve assembly 4 is provided on the left water tank 1, the right water tank 2 and the rear water tank 3 to control the inflow and outflow of water or gas. The water stop valve assembly 4 generally includes normally closed electromagnetic valves, seals, pipes and other components to ensure that the water tanks can be quickly and safely filled with water or drained when needed. The water stop valve assembly 4 also includes a control system and sensors to achieve more accurate water level control and stability adjustment. The water stop valve assembly 4 is a prior art and will not be elaborated in this section. The left, right, and rear water tanks 1, 2, and 3 are all made of 304 stainless steel. Arc-shaped end caps 5 are welded to each end of the left, right, and rear water tanks 3 using a circumferential seam sealing process, ensuring the weld's tightness and compressive strength. The arc-shaped end caps 5 can better disperse pressure and reduce local stress concentration. When under pressure, the arc-shaped end caps 5 can more effectively resist deformation and maintain structural stability, ensuring they meet compressive resistance requirements. Furthermore, the choice of arc-shaped end caps 5 and 304 stainless steel material ensures that the arc-shaped end caps 5 offer a higher pressure-bearing capacity than flat plate seals. Therefore, the arc-shaped end caps 5 are lighter than flat plate seals under the same pressure, achieving higher pressure resistance and lighter weight, thereby improving the safety and stability of the submersible in deep-sea environments. The environmental conditions required for welding with 304 stainless steel are relatively easy to achieve using this technology, and current underwater wet welding technology and processes can be addressed on-site.

In this way, in an emergency, if the water in the water tank cannot be discharged or if the submersible suddenly dives due to a seawater fault, the propeller in the water tank can also be used to float up.
