Description

Technical Field

[0001] The present invention relates to the technical field of icebreaking, and in particular to an underwater projectile icebreaking and water discharge device. Background Art

[0002] With global climate change, the melting of polar ice caps is accelerating, posing challenges to polar resource development and maritime transportation. Traditional icebreakers are prone to ice damage when interacting with thick ice, necessitating the development of new icebreaking technologies, such as projectile penetration methods. Influenced by the natural environment, projectile trajectory, and attitude adjustment, projectiles often have a certain initial penetration angle before penetrating the ice in real-world scenarios. Therefore, exploring the crack propagation patterns and damage mechanisms during projectile penetration and icebreaking at different penetration angles is of great research value, potentially helping to improve the effectiveness of icebreaking ammunition, optimize the structural design of icebreaking projectiles, reduce icebreaking costs, and improve icebreaking efficiency.

[0003] Publication number CN119533216A discloses a projectile penetration and icebreaking test device, which includes a frame, a projectile launch assembly, a positioning fixture, a protective assembly, and an image capture assembly. The bottom of the projectile launch assembly is a launch end pointing toward a horizontal test surface, and the projectile launch assembly is rotatably connected to the frame within a vertical plane. The positioning fixture secures the sample to the horizontal test surface of the frame, and the tilt angle of the launch end can be adjusted by rotating the projectile launch assembly. The image capture assembly collects image information of the sample, thereby studying the impact damage of the projectile on the sample at different penetration angles. This solution allows the position and angle of the barrel above water to be precisely adjusted using a slider, a rotating structure, and a laser pointer, enabling the study of the impact damage of the projectile on the sample at different penetration angles.

[0004] However, during the icebreaking and water exiting test, the laser pointer could not be used underwater, making it difficult to adjust the barrel to aim at the center of the ice layer, resulting in low test efficiency and an inability to accurately simulate the process of the projectile obliquely penetrating the ice layer underwater in a real scenario.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In order to solve the technical problem that when the existing icebreaking test device conducts an underwater icebreaking test, it is inconvenient to adjust the inclination angle of the underwater barrel, and the barrel is difficult to align with the center of the ice layer, resulting in low test efficiency, the present invention provides an underwater projectile icebreaking water discharge device, which is convenient for adjusting the launch angle of the projectile underwater. At the same time, the positioning structure is used to ensure that the missile tube can be accurately aligned with the center of the ice layer in the placement area, solving the problems of the underwater icebreaking test device in the prior art in adjusting the inclination angle of the barrel and aligning with the center of the ice layer.

[0021] See also Figure 1 and Figure 2The underwater projectile icebreaking and water-discharging device includes: a container body 1, a missile tube body 2, an adjustment structure 3 and a positioning structure 4. The top of the container body 1 is provided with an opening, and a placement area for placing a sample is formed in the opening; the missile tube body 2 is rotatably mounted on the container body 1 for guiding the projectile 21 to be launched; the adjustment structure 3 is connected to the missile tube body 2 and the container body 1 for driving the missile tube body 2 to rotate relative to the container body 1; the positioning structure 4 is movably mounted on the tube mouth of the missile tube body 2, and it has a first position and a second position. When the positioning structure 4 is in the first position, one end of the positioning structure 4 is coaxial with the missile tube body 2 and is located on a side of the missile tube body close to the placement area; when the positioning structure 4 is in the second position, it is staggered with the tube mouth of the missile tube body 2.

[0022] In this device, a container body 1 provides a closed underwater environment. The opening at the top of the container body 1 forms a placement area for placing ice sheets. A missile tube 2 is positioned within the container body 1, guiding the launch of a missile 21 and allowing the inclination angle of the missile tube 2 to be varied via an adjustment structure 3. During the adjustment process, a positioning structure 4 can be adjusted to a first position. In this position, one end of the positioning structure 4 is coaxial with the missile tube 2 and located on the side of the missile tube 2 near the placement area, accurately indicating the launch direction and position of the missile 21. This positioning structure 4 extends the length of the missile tube 2 along its axial direction, reducing the distance between the missile tube 2 and the ice layer, thereby more accurately positioning the missile tube 2 relative to the ice layer. This allows the positioning structure 4 to accurately determine the inclination of the missile tube 2, ensuring that the missile 21 accurately hits the target area, i.e., the center of the ice layer, upon launch. Once the missile tube 2 is adjusted to the desired inclination angle, the positioning structure 4 can be switched to a second position. In this position, the positioning structure 4 is offset from the tube opening of the missile tube 2, preventing interference from the positioning structure 4 with the launch of the missile 21. The entire device has a compact structure and is easy to operate. It can achieve accurate launch of the projectile 21 in an underwater environment and has high practicality and reliability.

[0023] See also Figure 1 and Figure 2 In some possible embodiments, the container body 1 is composed of a water tank 11 and a top plate 12. The water tank 11 stores a certain amount of water for simulating an underwater environment. The top plate 12 is provided on both sides of the top of the water tank 11 to provide support for the ice plate.

[0024] Furthermore, a bracket 15 is mounted on top of the water tank 11, and a laser level 16 is mounted on the bracket 15. The laser level 16 generates a crosshair to accurately locate the center of the ice plate. The crosshairs of the laser level 16 are projected onto the placement area, allowing the operator to clearly observe the alignment of the ice plate center with the launch direction of the missile tube 2. By adjusting the tilt angle of the missile tube 2 and combining it with the indication of the laser level 16, the launch direction of the missile tube 2 can be accurately aligned with the center of the ice plate.

[0025] See also Figure 2 and Figure 3 In this embodiment, a through slot 13 is formed at the bottom of the water tank 11. The missile tube 2 is pivotally mounted to the bottom of the container body 1. Its sidewalls are pivotally connected to the walls of the through slot 13 via a rotating shaft, allowing it to rotate relative to the water tank 11 to adjust the launch angle of the missile 21. Furthermore, one end of the missile tube 2 is located inside the water tank 11, while the other end extends outside the bottom of the water tank 11. An adjustment structure 3 is mounted at the bottom of the water tank 11 and connected to the end of the missile tube 2 located outside the water tank 11. By locating one end of the missile tube 2 and the adjustment structure 3 outside the water tank 11, operators can easily adjust the tilt angle of the missile tube 2 from outside the water tank 11 without having to enter the container body 1, improving operational safety and convenience. Furthermore, locating one end of the missile tube 2 outside the water tank 11 facilitates connection to the missile launch mechanism 8 and facilitates the operator's transfer of the missile 21 from the bottom of the missile tube 2 into the missile tube 2.

[0026] Furthermore, to prevent water from leaking from the water tank 11 through the through groove 13, in this embodiment, a seal 14 is provided within the through groove 13, connecting the container body 1 and the missile body 2. This seal 14 seals the gap between the missile body 2 and the water tank 11 without affecting the movement of the missile body 2. The seal 14 is made of a flexible material, such as a flexible airbag, which has a certain degree of elasticity and can expand or contract accordingly with the movement of the missile body 2, thereby ensuring a good seal. In a specific application, two flexible seals 14 are provided, one at the top and one at the bottom of the through groove 13. The outer side of the flexible airbag seals against the wall of the through groove 13, while the inner side seals against the outer wall of the missile body 2. This maintains a good seal during rotation of the missile body 2, regardless of its tilt angle, effectively preventing water from leaking from the water tank 11.

[0027] See also Figure 2 and Figure 3 In this embodiment, the adjustment structure 3 includes at least two adjustment members 31, which are respectively arranged on both sides of the missile tube body 2. Each adjustment member 31 has a connection end connected to the container body 1 and an operating end that abuts the missile tube body 2. The multiple operating ends are used to synchronously move relative to the missile tube body 2 on both sides of the missile tube body 2. When the adjustment member 31 on one side pushes toward the missile tube body 2, the corresponding adjustment member 31 on the other side synchronously retracts in the opposite direction. The synchronous action of the two sides can adjust the inclination angle of the missile tube body 2 while abutting against the two sides of the missile tube body 2 to maintain the stability of the missile tube body 2.

[0028] In one embodiment, two adjustment members 31 are provided, one on each side of the missile tube 2, each including an abutment screw 311. A fixing bracket 17 for mounting the abutment screws 311 is provided at the bottom of the water tank 11. The two abutment screws 311 are threadedly connected to the fixing bracket 17 on either side, and the adjacent ends of the abutment screws 311 abut against the outer wall of the missile tube 2. Rotating the abutment screws 311 can push the missile tube 2 about the rotation axis, thereby adjusting the inclination angle of the missile tube 2 to achieve oblique impacts on ice layers at different angles. Furthermore, an angle dial is provided on the rotary adjustment member 31 to accurately display the current inclination angle of the missile tube 2, facilitating accurate adjustment to a predetermined angle.

[0029] It should be noted that the simultaneous action of the abutment screws 311 on both sides of the missile tube 2 does not necessarily mean that the displacement on both sides must be the same. When the tilt angle of the abutment screws 311 changes, the displacement of the abutment screws 311 on both sides can be different according to the different rotation angles, ensuring that the abutment screws 311 can always stably adjust the side of the missile tube 2.

[0030] Of course, in other possible embodiments, the missile tube body 2 can also be installed inside the water tank 11, and the adjustment member 31 is an electric drive element such as a cylinder or an electric telescopic rod. By controlling the extension and contraction of the electric drive element, the missile tube body 2 is driven to rotate around the rotating axis, thereby realizing the adjustment of the inclination angle of the missile tube body 2.

[0031] In order to realize the switching of the positioning structure 4 between the first position and the second position, please refer to Figure 2 and Figure 4 In this embodiment, the positioning structure 4 comprises a positioning portion 41, a telescopic portion 42, and a telescopic drive. The positioning portion 41 is connected to the missile tube 2 and defines a guide path. The telescopic portion 42 is connected to the positioning portion 41 and is movable along the guide path. When the positioning structure 4 is in a first position, the guide path is parallel to or coincides with the axis of the missile tube 2. The axis of the telescopic portion 42 coincides with the axis of the missile tube 2, ensuring that the telescopic portion 42 remains axially aligned with the missile tube 2 as it moves along the guide path. The telescopic drive connects the positioning portion 41 and the telescopic portion 42 and is used to drive the telescopic portion 42 along the guide path of the positioning portion 41. This design allows the telescopic portion 42 to be driven along the guide path of the positioning portion 41 by the telescopic drive if the inclination angle of the missile tube 2 or the ice plate height changes, thereby adjusting the length of the positioning structure 4 so that one end of the positioning structure 4 can always accurately indicate the center of the ice plate, thereby maintaining alignment between the launch direction of the missile tube 2 and the ice plate center.

[0032] In some possible embodiments, the positioning portion 41 is internally provided with a chute, which forms the guide path. One end of the telescopic portion 42 is disposed within the chute and is slidably connected thereto. When the positioning structure 4 is in the first position, the axis of the chute coincides with the axis of the missile tube 2. A telescopic drive element can drive the telescopic portion 42 to slide and retract within the chute, thereby accurately indicating the launch direction of the missile tube 2.

[0033] In some possible embodiments, the positioning structure 4 and the missile tube 2 are mounted using a rotational connection, allowing the positioning structure 4 to switch between a first position and a second position by rotation. Specifically, one end of the positioning structure 4 is rotationally connected to the missile tube 2, with one end coaxially sleeved on the tube mouth of the missile tube 2. The positioning structure 4 has a first position in which one end coaxially sleeves onto the tube mouth of the missile tube 2, and a second position in which the positioning structure 4 is tilted outward from the first position to the side of the missile tube 2.

[0034] Preferably, see Figure 2 and Figure 4 In this embodiment, the positioning portion 41 comprises a sleeve 411 and a base 412. The telescopic portion 42 comprises a slide rod 421 and an indicator rod 422. A rotating seat 22 is provided on the side of the missile tube 2. One end of the base 412 is connected to the rotating seat 22. A groove is defined on one side of the base 412, and a flexible rubber pad is embedded in the groove. This allows the base 412 to smoothly fit over the nozzle of the missile tube 2 when it is rotated to the nozzle, thereby ensuring the stability of the positioning structure 4. A sliding groove is defined within the sleeve 411. One end of the slide rod 421 extends into the groove and slides into connection therewith. The other end of the slide rod 421 is coaxially connected to the indicator rod 422. The indicator rod 422 has a pointed end located on the central axis of the slide rod 421, indicating the launch centerline of the missile 21 and ensuring that the missile 21 accurately impacts the predetermined position on the ice plate.

[0035] It should be noted that in this embodiment, the telescopic drive member can be a drive element such as an electric push rod, an air cylinder, or a hydraulic cylinder. It can also be an electric motor or an air compressor. When an electric motor is used as the power source, the motor's rotational motion can be converted into linear motion of the telescopic portion 42 through a transmission method such as a screw-nut mechanism. When an air compressor is used as the power source, the compressed gas output port of the air compressor is connected to the cavity between the slide rod 421 and the sleeve 411, and the compressed gas can be delivered to the slide groove. At the same time, a sealing ring is provided at the sliding end of the slide rod 421, thereby converting the pressure energy of the compressed air into linear motion of the telescopic portion 42. This structure can adjust the height of the indicator rod 422 to accommodate gun barrels of different depths and ice slabs at different positions, and can adapt to the position adjustment between the gun barrel and the ice layer.

[0036] See also Figure 4In some possible embodiments, the device further includes a drive structure 5 mounted on the missile tube 2, with its drive end connected to the positioning structure 4 for driving the positioning structure 4 to switch between the first and second positions. The drive structure 5 employs a rotary drive motor or electric shaft mounted on the rotating base 22, with its drive end connected to the base 412. The switching of the positioning structure 4 between the first and second positions is achieved by the forward and reverse rotation of the rotary motor or electric shaft.

[0037] When firing the projectile 21, the drive structure 5 can be used to drive the indicator rod 422, sleeve 411, slide rod 421 and base 412 to move away from the nozzle of the barrel to avoid interfering with the firing of the projectile 21. After the firing is completed, the drive structure 5 drives the indicator rod 422 and other structures to reset, and the indicator rod 422 once again indicates the firing centerline of the projectile 21, preparing for the next firing.

[0038] Of course, in other possible embodiments, the positioning structure 4 and the missile tube body 2 can also be installed in a sliding connection manner, so that the positioning structure 4 can switch between the first position and the second position by sliding. In this case, the driving structure 5 can be a driving element such as a cylinder or an electric push rod, which is installed on the missile tube body 2 or the container body 1, and the movable end is connected to the positioning structure 4. The positioning structure 4 is driven to slide at the tube mouth, thereby achieving the switching of the positioning structure 4 between the first position and the second position.

[0039] To fix and adjust the position of the ice plate, please refer to Figure 1 In this embodiment, the underwater missile icebreaking and water discharge device further includes a fixing mechanism 6 and a positioning mechanism 7. The fixing mechanism 6 includes a positioning member 61 and a pressing member 62. The positioning member 61 is located in the placement area and is used to place the sample. The pressing member 62 is connected to the positioning member 61 and has a pressing end that can move relative to the positioning member 61, which is used to press the sample into the placement area, thereby securing the ice sheet. The adjustment structure 3 connects the container body 1 and the fixing mechanism 6 and is used to drive the sample fixed by the fixing mechanism 6 to move in the direction indicated by the nozzle when the missile tube 2 is tilted, thereby adjusting the position of the ice sheet.

[0040] See also Figure 1 、 Figure 5 and Figure 6In one embodiment, four fixing mechanisms 6 are provided, and the four fixing mechanisms 6 are distributed at the four sides or four corners of the placement area. The positioning members 61 include a positioning seat 611, and the pressing members 62 include a lateral adjustment cylinder 621, a connecting seat 622, a vertical adjustment screw 623 and a fixed splint 624. The positioning seat 611 is installed on the top plate 12 of the water tank 11, and the lateral adjustment cylinder 621 is installed on the positioning seat 611. The connecting seat 622 is connected to the output shaft of the lateral adjustment cylinder 621. The vertical adjustment screw 623 is screwed on the connecting seat 622, and its bottom end is connected to the fixed splint 624. A handle is provided on the top, and the fixed splint 624 is slidably connected to the inner wall of the connecting seat 622. When in use, the vertical adjustment screw 623 is driven to rotate by operating the handle, thereby adjusting the position of the fixed clamp 624 in the vertical direction, so that ice plates of different thicknesses can be clamped and fixed. The lateral position of the connecting seat 622 can be adjusted by the telescopic movement of the lateral adjustment cylinder 621, so that ice plates of different widths or lengths can be clamped and fixed.

[0041] See also Figure 1 、 Figures 5 to 7 In some possible embodiments, two positioning mechanisms 7 are provided, with each of two fixing mechanisms 6 mounted on one positioning mechanism 7. The positioning mechanisms 7 can adjust the lateral position of the two fixing mechanisms 6, enabling the horizontal position of the ice sheet to be adjusted. The positioning mechanism 7 comprises an adjustment plate 71, a connecting plate 72, and a fixing bolt 73. The adjustment plate 71 is mounted on the top plate and is fixedly connected to the top plate by being positioned within a mounting groove within the positioning seat 611. The connecting plate 72 has a through hole through which the fixing bolt 73 passes and is threadedly engaged with a threaded groove. This allows the positioning seat 611 to move along the length of the adjustment plate 71, thereby moving the fixing mechanisms 6 and the ice sheet held therein. By rotating the fixing bolt 73, the fixing mechanism 6 is abutted against the adjustment plate 71, securing the position of the fixing mechanism 6 and achieving precise adjustment of the ice sheet's horizontal position. This facilitates the ability to move the ice sheet to align its center with the missile tube 2 according to its angular position during experiments, or to rotate the missile tube 2 after moving the ice sheet to a desired position so that its center aligns with the center of the ice sheet.

[0042] Furthermore, on both sides of the positioning seat 611, there are also limited guide rails 74 to ensure the stability of the positioning seat 611. The length direction of the limited guide rails 74 is consistent with the width direction of the adjustment plate 71, so that the positioning seat 611 can move smoothly along the limited guide rails 74, and the limited guide rails 74 prevent the positioning seat 611 from partially moving upward. Of course, in other possible embodiments, the fixing mechanism 6 and the positioning mechanism 7 can also take other forms. For example, the fixing mechanism 6 can use a vacuum suction cup, which generates negative pressure to attract the ice sheet and secure it. The positioning mechanism 7 can use a transmission element such as a screw-nut mechanism or a linear module. By controlling the movement of the transmission element, the fixing mechanism 6 and the secured ice sheet can be moved in a predetermined direction, thereby achieving precise adjustment of the ice sheet's position.

[0043] See also Figures 1 to 3 In some possible embodiments, the device further includes a projectile launching mechanism 8, which includes a transfer box 81, an air compressor 82, a gas valve 83, and an air pipe 84. The transfer box 81 is installed at the bottom of the missile tube 2. The bottom of the missile tube 2 is also provided with a projectile installation port and a valve for opening and closing the installation port. The air compressor 82 is connected to the transfer box 81 via the air pipe 84 and the gas valve 83. The air compressor 82 can fill the transfer box 81 with high-pressure gas through the air pipe 84 and the gas valve 83. The high-pressure gas pushes the projectile 21 upward along the missile tube 2 until the projectile 21 is ejected from the tube port of the missile tube 2, thereby impacting the ice plate.

[0044] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the present invention is described in detail: During the icebreaking test, an ice sheet is placed on a positioning seat 611. The position of the fixing clamp 624 is adjusted using a horizontal adjustment cylinder 621 and a vertical adjustment screw 623 to secure the ice sheet. The ice sheet is then adjusted using the positioning mechanism 7 so that its center aligns with the launch direction of the missile tube 2. Alternatively, the inclination angle of the missile tube 2 is adjusted using the adjustment structure 3 so that the launch direction aligns with the center of the ice sheet. During the alignment process, the length of the positioning structure 4 is adjusted using a telescopic drive to ensure that one end of the indicator rod 422 accurately points to the ice sheet. Simultaneously, with the assistance of a laser level 16, the launch direction is precisely aligned with the center of the ice sheet. Finally, the missile launch mechanism 8 is activated, and an air compressor 82 fills the transfer box 81 with high-pressure gas through an air pipe 84 and a gas valve 83. The high-pressure gas propels the missile 21, which is placed in the missile installation port, rapidly upward through the missile tube 2 to conduct the icebreaking test.

[0045] The present invention comprises a container body 1, a missile tube 2, an adjustment structure 3, and a positioning structure 4. The container body 1 provides a closed underwater environment, the missile tube 2 guides the missile body 21 for launch, the adjustment structure 3 enables flexible adjustment of the inclination angle of the missile tube 2, and the positioning structure extends the missile tube 2's length along its axial direction, reducing the distance between the missile tube 2 and the ice layer, ensuring that the missile tube 2 can accurately align with the sample within the placement area, i.e., the center of the ice layer during icebreaking tests. The device of the present invention has a compact structure and is easy to operate. It can accurately simulate the process of a missile body 21 obliquely penetrating ice underwater in a real-world scenario, resolving issues with prior art underwater icebreaking test devices regarding adjusting the barrel's inclination angle and aligning with the ice layer center, providing strong experimental support for icebreaking technology research.
