Description

Technical Field

[0001] This application relates to the field of submarine icebreaking test research, and in particular to a test device and test method for measuring the icebreaking load of a submarine surfacing. Background Technology

[0002] The polar regions possess immense political, economic, and military value, holding an extremely important strategic position. To ensure the smooth development of these regions, guarantee safe navigation, and maintain geostrategic control over this unique area, it is essential to guarantee submarines the ability to operate freely in the polar regions. Among these capabilities, the submarine's icebreaking and surfacing ability is a crucial element in achieving strategic deterrence and military strikes.

[0003] During the process of a submarine surfacing from beneath the ice and breaking through it, the submarine not only needs to complete the cross-medium movement from the seabed to the surface, but also needs to directly withstand the impact force when hitting the ice. The submarine's surfacing angle and surfacing speed directly affect the forces acting on it. Therefore, the force situation during the submarine icebreaking process is quite complex, and corresponding experiments are needed to verify the forces acting on the submarine during icebreaking.

[0004] However, there are currently few publicly available research records on submarine icebreaking and surfacing. Furthermore, due to the special nature and secrecy of submarines, conducting polar icebreaking and surfacing tests is quite difficult. Therefore, establishing a systematic research methodology for submarine icebreaking and surfacing is particularly important. At present, research on submarine icebreaking is still in its early stages, lacking effective experimental methods to simulate polar ice zones and submarine icebreaking. Summary of the Invention

[0051] During the process of a submarine surfacing from beneath the ice and breaking through it, the submarine not only needs to complete the cross-medium movement from the seabed to the surface, but also needs to directly withstand the impact force when hitting the ice. The submarine's surfacing angle and surfacing speed directly affect the forces acting on it. Therefore, the force situation during the submarine icebreaking process is quite complex, and corresponding experiments are needed to verify the forces acting on the submarine during icebreaking.

[0052] However, there are currently few publicly available research records on submarine icebreaking and surfacing. Furthermore, due to the special nature and secrecy of submarines, conducting polar icebreaking and surfacing tests is quite difficult. Therefore, establishing a systematic research methodology for submarine icebreaking and surfacing is particularly important. At present, research on submarine icebreaking is still in its early stages, lacking effective experimental methods to simulate polar ice zones and submarine icebreaking.

[0053] In response, this application proposes an experimental device for measuring the icebreaking load of a submarine during surfacing. The device can adjust the surfacing position, surfacing speed, and surfacing angle of the submarine model 531 through the moving component 300, the lifting component 400, and the angle adjustment component 500, thereby simulating different icebreaking conditions. Furthermore, the device records the icebreaking process of the submarine model 531 through the force sensor 610 and the camera 620, providing simulated data support for the icebreaking force conditions of the submarine.

[0054] In addition, this application also proposes a test method based on the above-mentioned test device for measuring the ice-breaking load of submarine surfacing. After the ice block 230 is fixed in the test box 100 by the ice block clamp 200, the movement of the submarine model 531 can be controlled by the moving component 300, the lifting component 400 and the angle adjustment component 500, thereby meeting different test requirements.

[0055] Reference Figures 1 to 4The experimental apparatus for measuring the icebreaking load of a submarine during surfacing, according to the first aspect of this application, includes a test chamber 100, an ice block clamp 200, a moving component 300, a lifting component 400, an angle adjustment component 500, and an observation component. The test chamber 100 is used for conducting submarine surfacing and icebreaking tests. The ice block clamp 200, moving component 300, lifting component 400, and angle adjustment component 500 are all located inside the test chamber 100. The ice block clamp 200 is used to fix ice blocks, the moving component 300 is used to drive the submarine model 531 to move horizontally, the lifting component 400 is used to drive the submarine model 531 to move vertically, and the angle adjustment component 500 is used to adjust the pitch angle of the submarine model 531. The observation component is used to record the force conditions and the surface attitude of the submarine model 531 during the icebreaking process.

[0056] Specifically, the test chamber 100 is filled with water. An ice clamp 200 is installed in the test chamber 100, and the ice it holds is positioned at the water surface of the test chamber 100.

[0057] Reference Figure 2 The moving component 300 includes a track 310 and a moving platform 320. The track 310 is installed at the bottom of the test chamber 100, and the moving platform 320 is slidably connected to the track 310, so that the moving platform 320 can move horizontally along the track 310.

[0058] Reference Figure 3 The lifting assembly 400 includes a support platform 410 and a lifting mechanism 420. The lifting mechanism 420 is connected to the moving platform 320, and the support platform 410 is installed on top of the lifting mechanism 420, so that the support platform 410 can move vertically under the drive of the lifting mechanism 420, thereby adjusting the height of the support platform 410.

[0059] Reference Figure 4 The angle adjustment assembly 500 includes a first adjustment rod 510, a second adjustment rod 520, and a submarine clamp 530. The two ends of the first adjustment rod 510 are respectively hinged to the support platform 410 and the submarine clamp 530, and the two ends of the second adjustment rod 520 are respectively hinged to the support platform 410 and the submarine clamp 530. Adjusting the length of the first adjustment rod 510 and the second adjustment rod 520 can change the pitch angle of the submarine clamp 530, thereby changing the pitch angle of the submarine model 531 when it surfaces.

[0060] Furthermore, referring to Figure 5The angle adjustment assembly 500 also includes a pressure gauge 540 and a hydraulic control system 550. The hydraulic control system 550 outputs hydraulic oil to the first adjusting rod 510 and the second adjusting rod 520 to adjust the extension length, enabling precise control of the first adjusting rod 510 and the second adjusting rod 520 respectively. The pressure gauge 540 is connected to the hydraulic control system 550 to display the output pressure, facilitating closed-loop control of the first adjusting rod 510 and the second adjusting rod 520.

[0061] Reference Figure 1 and Figure 4 The observation components include a force sensor 610 and a camera 620. Two force sensors 610 are installed, one-to-one with the first adjusting rod 510 and the second adjusting rod 520, respectively, and can indirectly detect the forces acting on the submarine model 531 in various directions. The camera 620 is mounted beside the test chamber 100 to record the submarine's icebreaking process. A transparent observation window 130 is provided on the side of the test chamber 100 for the camera 620 to film the test process. Furthermore, the number of observation windows 130 can be set to two, positioned opposite each other, with a light installed next to the other observation window 130 to improve the image quality captured by the camera 620.

[0062] Specifically, in this embodiment, the force sensor 610 is a three-axis force sensor, which can detect the magnitude of the forces acting on the submarine model 531 in the X, Y, and Z axes, thereby reproducing as closely as possible the force situation of the submarine during the surfacing and icebreaking process. It should be noted that the three-axis force sensor is an existing technology, and its specific structure and working principle will not be described in detail here.

[0063] Furthermore, referring to Figure 6 The test chamber 100 is equipped with an inlet pipe 140 and an outlet pipe 150. The inlet pipe 140 is located at the top of the test chamber 100 and is used to introduce cold water into the test chamber 100; the outlet pipe 150 is located at the bottom of the test chamber 100 and can discharge the cold water in the test chamber 100 after the test is completed.

[0064] Furthermore, referring to Figure 7 The test chamber 100 is equipped with a support plate 110, which extends into the test chamber 100 to support the ice block clamp 200.

[0065] For ice cube clamp 200, refer to Figure 8The ice block clamp 200 includes C-shaped steel beams 210 and ribs 220. The C-shaped steel beams 210 have a "C"-shaped cross-section, and there are multiple beams welded together to form a frame structure, constituting the main frame of the ice block clamp 200. The ribs 220 are installed inside the C-shaped steel beams 210 to increase structural rigidity. This prevents the C-shaped steel beams 210 from deforming under the pressure of the ice block 230, and also increases the contact area between the ice block clamp 200 and the ice block 230, improving the bonding strength between them.

[0066] Furthermore, referring to Figure 8 The C-shaped steel beam 210 has a first pin hole 211; refer to Figure 6 The test chamber 100 has a second pin hole 120 on its side wall. The test device for measuring the ice-breaking load of the submarine surfacing also includes a fixing pin, which passes through the first pin hole 211 and the second pin hole 120 to achieve pin limiting, in order to prevent the submarine model 531 from lifting the ice block clamp 200 along with it during the process of surfacing and breaking the ice block 230, which would lead to test failure.

[0067] Furthermore, the moving component 300 also includes a moving drive component 330, whose two ends are respectively connected to the test chamber 100 and the moving platform 320. The moving drive component 330 is used to drive the moving platform 320 to move. The moving drive component 330 can specifically be an electric actuator, a hydraulic actuator, or an air actuator, or other mechanisms or devices that can extend and retract to drive the moving platform 320 to move.

[0068] Specifically, the lifting mechanism 420 includes a scissor mechanism 421 and a telescopic power member 422. The bottom of the scissor mechanism 421 is connected to the moving platform 320, the top of the scissor mechanism 421 is connected to the supporting platform 410, and the telescopic power member 422 is connected to the scissor mechanism 421 to drive the scissor mechanism 421 to deform.

[0069] Specifically, rollers 4211 are provided at both the top and bottom of the scissor lift mechanism 421. During the deformation process of the scissor lift mechanism 421, the rollers 4211 roll accordingly, acting as driven wheels to assist the scissor lift mechanism 421 in completing the deformation. The scissor lift mechanism 421 is a prior art, and its specific structure and working principle will not be described in detail here.

[0070] Furthermore, the experimental apparatus for measuring the icebreaking load on the submarine surface also includes a refrigerator 700 and an ice-making mold 800. The ice-making mold 800 is installed inside the refrigerator 700, and the ice block clamp 200 can be placed in the ice-making mold 800. During the ice-making process, the ice-making mold 800 is filled with water, and the refrigerator 700 transfers cold energy to the ice-making mold 800 to make ice. After the ice is prepared, it can be solidified with the ice block clamp 200. Subsequently, the ice block clamp 200 can be removed from the ice-making mold 800 to obtain the ice block 230 required for the test.

[0071] Specifically, the refrigerator 700 can generate cooling capacity using dry ice refrigeration, liquid nitrogen refrigeration, or heat exchange equipment to complete the ice-making process. In this embodiment, the refrigerator 700 has a cold water inlet connected to a chiller 710, which can supply cold water to the refrigerator 700. (Refer to...) Figure 10 and Figure 11 The ice mold 800 is disc-shaped, and the refrigerator 700 is equipped with a mold support 720, on which the ice mold 800 can be placed.

[0072] Before ice making, salt is added to water to obtain a high-concentration brine solution, which allows the brine solution to remain liquid even at sub-zero temperatures. A chiller 710 then cools the brine solution and outputs it to the ice maker 700. The coldness of the brine solution is transferred to the water in the ice mold 800, causing it to freeze. For subsequent demolding, the ice mold 800, along with the ice clamp 200, can be immersed in cold water to melt the ice layer between the ice mold 800 and the ice clamp 200, facilitating demolding.

[0073] Furthermore, the experimental device for measuring the icebreaking load on the surface of this submarine also includes a crane 900, an ice-making mold 800, and an ice block clamp 200, all equipped with lifting rings. The hook of the crane 900 can extend into the lifting rings to lift the ice-making mold 800 or the ice block clamp 200 and transfer its position.

[0074] A test method according to a second aspect of this application, based on the aforementioned test apparatus for measuring the icebreaking load during submarine surfacing, includes the following steps:

[0075] S100. Ice is made on the ice clamp 200 according to the test requirements;

[0076] S200. Fill the test chamber 100 with water and set up a camera 620 next to the test chamber 100;

[0077] S300. Secure the submarine model 531 to the submarine clamp 530;

[0078] S400. Adjust one end of the moving platform 320 to the track 310, lower the lifting mechanism 420, and adjust the length of the first adjusting rod 510 and the second adjusting rod 520 to change the pitch angle of the submarine clamp 530;

[0079] S500. After the ice block 230 and the ice block clamp 200 have solidified, transfer the ice block clamp 200 along with the ice block 230 to the test chamber 100.

[0080] S600. The test begins. Camera 620 is activated. The moving platform 320, lifting mechanism 420, first adjusting rod 510 and second adjusting rod 520 move together, causing the submarine model 531 to break through the ice block 230 and float to the surface.

[0081] S700. Based on the force data detected by the force sensor 610 and the images captured by the camera 620, analyze the icebreaking force situation of the submarine model 531.

[0082] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
