Description

Technical Field

[0001] The present invention belongs to the field of damage to marine structures, and particularly relates to a device and method for increasing bubble pulsation energy and jet load by using chemical energy. Background Art

[0002] With the development of technology, the damage effect of high-pressure bubbles on marine structures has come into the view of researchers. When the pulsation frequency of high-pressure bubbles is close to the natural frequency of the structure, it will cause serious overall structural damage or instability. At the same time, the damage effect of bubble jet load focuses on the local characteristics of the structure and causes impact on the surface of the marine structure. The action of high-pressure pulsating bubbles on a ship can generate dynamic bending moments of hogging and sagging, which can then cause the ship to break in the middle as a whole, and can achieve the goal of destroying the ship at one time. High-pressure bubbles have good performance in both the overall damage and local damage of marine structures. Therefore, the role of underwater high-pressure bubbles cannot be ignored in the field of marine structure damage and protection.

[0003] Through multiple pulsations and jets, most of the energy of the bubbles will act on the marine structure. Therefore, increasing the pulsation energy of high-pressure bubbles can effectively enhance the damage effect on the structure. The energy source of underwater high-pressure bubbles is usually the energy released by the physical and chemical reactions of the carried substances themselves. For example, a new way to enhance the bubble energy is to carry combustible materials such as aluminum powder to release a large amount of heat and gas. The existing methods for enhancing bubble pulsation energy usually increase the amount of carried substances to increase the energy released by physical and chemical reactions, and the methods of considering underwater environmental factors to enhance high-pressure bubble energy are relatively rare. Therefore, using underwater environmental factors to enhance the pulsation energy and jet load of underwater bubbles by means of chemical reactions between the carried materials and water can provide a new idea for the generation and energy enhancement of underwater high-pressure bubbles. Summary of the Invention

[0004] In view of this, the present invention aims to provide a device and method for increasing bubble pulsation energy and jet load by using chemical energy to improve the traditional pulsation energy and jet load of underwater bubbles.

[0005] To achieve the above object, the present invention adopts the following technical solutions. According to one aspect of the present invention, there is provided a device for increasing bubble pulsation energy and jet load by using chemical energy, including:

[0006] A loading part, including an inner shell and an outer shell arranged in a nested manner. A plurality of prefabricated grooves are arranged at intervals on the outer shell. An energetic material is arranged in the inner shell. A containing cavity for containing a gas-producing material is formed between the outer shell and the inner shell. A plurality of water inlet channels communicating with the containing cavity are arranged on the outer shell;

[0007] The switch assembly is provided at the water inlet end of each of the water inlet channels, and is used to introduce water into the accommodation cavity unidirectionally after being opened.

[0008] The sonar guidance system is used to control the switch assembly to open the water inlet channel, and activate the energetic material after the gas mass generated by the reaction of the gas-producing material with water increases the pressure in the accommodation cavity and causes the outer shell to break at the prefabricated groove.

[0009] Furthermore, the shell further includes a guiding part provided at the front end of the loading part and a power propulsion part at the rear end, and the sonar guidance system is arranged in the guiding part.

[0010] Furthermore, the energetic material is connected to a trigger, and the trigger is connected to the sonar guidance system.

[0011] Furthermore, the switch assembly includes a rotatable circular shell, a chute, a telescopic support cross beam, a locking drive assembly and a check valve. The rotatable circular shell is connected to the inlet end of the corresponding water inlet channel. The telescopic support cross beam is slidably connected in the chute provided on the rotatable circular shell. An outer shell groove is provided on the side wall of the water inlet channel. The locking drive assembly is used to drive the telescopic support cross beam to insert into or withdraw from the outer shell groove. The check valve is arranged in the corresponding water inlet channel. After the rotatable circular shell is opened, water enters the accommodation cavity unidirectionally through the check valve.

[0012] Furthermore, the locking drive assembly includes an automatic wire winding machine, a high-strength cable, a spring inside the cross beam, a slidable buckle and an arc part. The movable end of the automatic wire winding machine is connected to the slidable buckle through a high-strength cable. The slidable buckle is slidably connected in the outer shell groove and the sliding direction is perpendicular to the sliding direction of the telescopic support cross beam. An arc part is provided at one end of the telescopic support cross beam close to the slidable buckle. One end of the spring inside the cross beam is connected to the rotatable circular shell, and the other end is connected to the telescopic support cross beam. When the slidable buckle is engaged with the arc part, the spring inside the cross beam is in a stretched state and the telescopic support cross beam is engaged in the outer shell groove. When the slidable buckle is disengaged from the arc part, the spring inside the cross beam resumes deformation and the telescopic support cross beam is disengaged from the outer shell groove.

[0013] Furthermore, the rotatable circular shell is rotatably connected to the side wall of the water inlet channel through a butterfly hinge.

[0014] Furthermore, the number of the rotatable circular shells is two and they are symmetrically arranged on both sides with respect to a fixed cross beam provided in the water inlet channel.

[0015] Furthermore, the check valve includes a check valve body, a check valve flap, a check valve spring, a diversion cover and a fixed support. A fixed support is arranged inside the check valve body. The check valve spring is sleeved on the fixed support. Two ends of the check valve spring are respectively connected to the fixed support and the check valve flap. Under normal state of the check valve spring, the check valve flap seals the inlet end of the check valve body.

[0016] Furthermore, the check valve body is of a Venturi tube structure.

[0017] According to another aspect of the present invention, a method for increasing the bubble pulsation energy and jet load of a device using chemical energy is provided, including the following steps: when the sonar guidance system detects a specified position, control the switch assembly to open, water enters the accommodation cavity unidirectionally through the water inlet channel and contacts the gas-producing material. After the gas-producing material reacts with water to generate a gas mass and separates and ruptures the outer shell along the prefabricated groove, the sonar guidance system sends a signal again to control the activation of the energy-containing material and release energy to disperse the inner shell, generating high-pressure bubbles and swallowing the gas mass generated by the reaction of the gas-producing material with water, so as to enhance the bubble pulsation energy and increase the jet load.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. High energy efficiency: By using the energy-containing material and the gas-producing material in cooperation, the gas-producing material first reacts with water to generate a gas mass and tear the outer shell, and then after the energy-containing material releases energy, the gas mass generated by the reaction of the gas-producing material with water is involved to enhance the bubble pulsation energy and jet load, so that the device can generate powerful bubble pulsation and jet underwater;

[0020] 2. Structural stability: The inner shell uses ceramic fiber material, which has good heat resistance and impact resistance, helps to protect the internal energy-containing material, and prevents the gas mass generated by the reaction of the gas-producing material with water from affecting the energy-containing material;

[0021] 3. Control mechanism: The device is equipped with an automatic wire winding machine and a telescopic support cross beam, allowing remote control of the activation and position adjustment of the device, increasing the flexibility and safety of operation. After the telescopic support cross beam is pulled out from the outer shell groove by controlling the automatic wire winding machine, the water pressure will turn the flip-up circular shell into the water inlet channel and then enter the accommodation cavity unidirectionally through the check valve to react with the gas-producing material, and the generated gas mass cannot be discharged from the water inlet channel under the action of the check valve, so that the gas mass energy accumulates to tear the outer shell and cooperate with the energy-containing material to increase the bubble pulsation and jet load of the gas mass;

[0022] 4. Check valve design: By controlling the unidirectional flow of gas and water through the check valve, it is ensured that the gas generated by the gas-producing material can effectively accumulate inside the device, providing the necessary pressure for the separation of the outer shell;

[0023] 5. Environmental adaptability: The housing design of the device allows it to break and disperse under water pressure, which helps reduce the hierarchical generation of bubbles and ensures the increasing effect of bubble pulsation and jet load;

[0024] 6. Energy release efficiency: By precisely controlling the activation timing and position of the energetic material through the sonar guidance system, the energy release effect can be maximized and unnecessary energy waste can be reduced;

[0025] 8. Modular design: Each component of the device, such as the check valve, the reversible circular housing, and the automatic wire winder, etc., is designed modularly, which is convenient for maintenance and replacement;

[0026] 9. Safety: Through remote control and automation mechanisms, the exposure of operators in dangerous environments is reduced, and the operation safety is improved; BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0040] Referring to the accompanying drawings to illustrate this implementation manner, according to one aspect of the present invention, a device for increasing the bubble pulsation energy and jet load using chemical energy is provided, including:

[0041] Loading part 2, including an inner housing 11 and an outer housing 12 arranged in a nested manner. A plurality of prefabricated grooves 4 are arranged at intervals on the outer housing 12. An energetic material 9 is arranged inside the inner housing 11. A containing cavity for containing the gas generation material 10 is formed between the outer housing 12 and the inner housing 11. A plurality of water inlet channels 6 communicating with the containing cavity are arranged on the outer housing 12; The inner housing 11 is specifically made of ceramic fiber material, which can prevent the heat generated by the reaction of the gas generation material with water from affecting the energetic material inside the inner housing. The inner housing 11 forms smaller fragments after the energetic material 9 releases energy, reducing the obstruction during the high-pressure bubble pulsation process. The gas generation material 10 is a material that can react violently with water to generate a gas mass, and any gas that can meet the test requirements can be used in this application, such as lithium hydride, etc. The setting of the prefabricated grooves 4 is to break the outer housing 12 along a predetermined trajectory after the gas generation material 10 reacts with water to generate a gas mass, facilitating the control of the reaction. At the same time, the neat breaking method can improve the efficiency of material recycling and ensure the integrity and recycling convenience of the material to the greatest extent.

[0042] The switch assembly is correspondingly arranged at the water inlet end of each of the water inlet channels 6 and is used to introduce water into the accommodating cavity unidirectionally after being opened. The switch assembly is arranged such that when the device moves to a pre-set position, water is introduced into the accommodating cavity through the opening of the switch assembly to react with the water, thereby generating an air mass. Then, after the air mass is generated, the switch assembly can prevent the gas from escaping, so that the energy accumulates in the accommodating cavity and tears the outer shell 12.

[0043] The sonar guidance system 7 is used to control the switch assembly to open the water inlet channel 6 and activate the energetic material 9 after the gas-producing material 10 reacts with water to generate an air mass, increasing the pressure in the accommodating cavity and causing the outer shell 12 to break at the prefabricated groove 4. The sonar guidance system 7 plays a role of positioning and control as a whole.

[0044] In this embodiment, the housing further includes a guiding portion 1 provided at the front end of the loading portion 2 and a power propulsion portion 3 provided at the rear end, and the sonar guidance system 7 is provided in the guiding portion 1. The sonar guidance system 7 also needs to control the power propulsion portion 3 to achieve the overall movement, floating and diving of the device. For the power propulsion portion 3, a traditional AUV power assembly can be used for driving, which will not be elaborated here.

[0045] In this embodiment, the energetic material 9 is connected to the trigger 8, and the trigger 8 is connected to the sonar guidance system 7. The trigger 8 can be a traditional commercially available one, and the sonar guidance system 7 controls the trigger 8 to activate the energetic material 9. The energetic material 9 can specifically be trinitrotoluene, the trigger 8 is a lead styphnate trigger, and the sonar guidance system 7 is connected to the trigger 8 by a conventional electrical connection method, which are all prior arts and will not be elaborated here.

[0046] In this embodiment, the switch assembly includes a rotatable circular housing 5, a chute 21, a telescopic support crossbeam 22, a locking drive assembly, and a one-way valve. The rotatable circular housing 5 is connected to the inlet end of the corresponding water inlet channel 6. The telescopic support crossbeam 22 is slidably connected in the chute 21 provided on the rotatable circular housing 5. An outer housing groove 28 is provided on the side wall of the water inlet channel 6. The locking drive assembly is used to drive the telescopic support crossbeam 22 to insert into or withdraw from the outer housing groove 28. The one-way valve is arranged in the corresponding water inlet channel 6. After the rotatable circular housing 5 is opened, water enters the accommodating cavity unidirectionally through the one-way valve. The specific connection form between the rotatable circular housing 5 and the inlet end of the water inlet channel 6 is a rotational connection. In the initial state, the telescopic support crossbeam 22 is inserted into the chute 21. In this case, it can withstand the underwater pressure to ensure that water does not enter the water inlet channel 6. A necessary sealing structure needs to be provided at the connection between the water inlet channel 6 and the rotatable circular housing 5 to ensure that there is no water leakage in the initial state. When the locking drive assembly drives the telescopic support crossbeam 22 to disengage from the chute 21, under the action of water pressure, the rotatable circular housing 5 will flip open into the water inlet channel 6, so that water enters the water inlet channel 6 and then opens the one-way valve under the action of water pressure, and then enters the accommodating cavity to react with the gas generating material 10 to generate an air mass.

[0047] For the switch assembly, an electrically controlled valve or other components that can actively control opening and closing can also be used for replacement, and the selection can be made according to actual needs and cost requirements. The locking drive assembly adopted in this application is driven in a manner independent of the loading part 2, which can minimize the influence of the energy released by the energetic material on the locking drive assembly, thereby reducing costs.

[0048] In this embodiment, the locking drive assembly includes an automatic wire winding machine 13, a high-strength cable 14, an internal spring 25 of the beam, a slidable buckle 26 and an arc-shaped portion 27. The movable end of the automatic wire winding machine 13 is connected to the slidable buckle 26 through the high-strength cable 14. The slidable buckle 26 is slidably connected to the groove 28 of the outer shell and the sliding direction is perpendicular to the sliding direction of the retractable support beam 22. The retractable support beam 22 is provided with an arc-shaped portion 27 near one end of the slidable buckle 26. One end of the internal spring 25 of the beam is connected to the flippable circular shell 5, and the other end is connected to the retractable support beam 22. When the slidable buckle 26 is engaged with the arc-shaped portion 27, the internal spring 25 of the beam is in a stretched state and the retractable support beam 22 is engaged in the groove 28 of the outer shell. When the slidable buckle 26 is disengaged from the arc-shaped portion 27, the internal spring 25 of the beam recovers its deformation and the retractable support beam 22 is disengaged from the groove 28 of the outer shell. The automatic winding machine 13 is specifically arranged in the power propulsion unit 3, and necessary protection is provided between the power propulsion unit 3 and the loading unit 2, so as to avoid the influence of bubbles on the power propulsion unit 3 and the automatic winding machine 13 as much as possible. The movable end of the automatic winding machine 13 is connected to the corresponding slidable buckle 26 through the high-strength cable 14, and is driven by the high-strength cable 14 as a medium. If it is damaged during use, the cost is low. During use, the high-strength cable 14 can be reversed by using some pulleys according to the specific structural design to ultimately achieve the purpose of driving each slidable buckle 26. It can be designed according to actual needs, which is not the focus of the present invention. It can be completed according to the hands-on ability of relevant technical personnel and will not be elaborated. The purpose of the internal spring 25 of the beam is to provide a certain preload force, so that the telescopic support beam 22 can be continuously engaged in the outer shell groove 28 when the slidable buckle 26 and the arc portion 27 are matched. When the slidable buckle 26 and the arc portion 27 are disengaged, the internal spring 25 of the beam can drive the telescopic support beam 22 to withdraw, thereby disengaging from the outer shell groove 28, so that the flip circular shell 5 can flip under the action of water pressure to introduce water after losing support. The slidable buckle 26 is specifically set to an L shape, and the hook of the L is used in conjunction with the arc portion 27. The slidable buckle 26 can be specifically arranged in a bilaterally symmetrical manner, and the corresponding arc portion 27 must be set accordingly. The symmetrical arrangement is evenly stressed and easy to adjust, and the high-strength cable 14 needs to be set accordingly at the same time.

[0049] In this embodiment, the flippable circular housing 5 is rotatably connected to the side wall of the water inlet channel 6 via a butterfly hinge 23 .

[0050] In this embodiment, two reversible circular shells 5 are provided and symmetrically arranged on both sides with respect to a fixed cross beam disposed in the water inlet passage 6. By means of this arrangement, the smooth rotation of the reversible circular shell 5 can be better ensured.

[0051] In this embodiment, the one-way valve includes a one-way valve body 31, a one-way valve flap 32, a one-way valve spring 33, a flow guide cover 34 and a fixed support 35. A fixed support 35 is disposed in the one-way valve body 31. The one-way valve spring 33 is sleeved on the fixed support 35. Two ends of the one-way valve spring 33 are respectively connected with the fixed support 35 and the one-way valve flap 32. Under normal conditions, the one-way valve flap 32 blocks the inlet end of the one-way valve body 31.

[0052] In this embodiment, the one-way valve body 31 has a Venturi tube structure. Water flows along the flow path formed by the flow guide cover 34. When passing through the flow path at the one-way valve flap 32, due to the reduction of the flow path area, the water movement speed increases to generate a pressure difference. The pressure difference before and after the one-way valve flap 32 forces the one-way valve spring 33 to compress, so that the one-way valve remains open. Figure 9 The arrow in shows the direction of water flow. When gas is generated in the accommodation cavity, as Figure 10 shown, the arrow shows the movement direction of the water-gas mixture or pure gas. The one-way valve will close to prevent the gas from escaping, and an accumulation is formed in the accommodation cavity to ensure that the outer shell 12 can be torn.

[0053] According to another aspect of the present invention, a method for increasing the bubble pulsation energy and jet load device by using chemical energy is provided, including the following steps: when the sonar guidance system 7 detects a specified position, control the switch assembly to open. Water enters the accommodation cavity unidirectionally from the water inlet passage 6 and contacts the gas generating material 10. After the gas generating material 10 reacts with water to generate a gas mass and separates and breaks the outer shell 12 along the preformed groove 4, the sonar guidance system 7 sends a signal again to control the activation of the energetic material 9 to disperse the inner shell 11, generate high-pressure bubbles and swallow the gas mass generated by the reaction of the gas generating material 10 and water, so as to enhance the bubble pulsation energy and increase the jet load.

[0054] Specifically, when the sonar guidance system 7 detects a specified position, it sends an electrical signal to the automatic cable winder 13 of the power propulsion unit 3. Under the drive of electricity, the automatic cable winder 13 starts to retract the high-strength cable 14. The position of the high-strength cable 14 is adjusted through a pulley, the slidable buckle 26 slides to both sides, and the telescopic support cross beam 22 retracts and disengages from the groove 28 of the outer shell. After the fixed connection between the rotatable circular shell 5 and the outer shell 12 disappears, under the action of water pressure, the rotatable circular shell 5 flips towards the inner layer of the water inlet channel 6, and water enters the accommodation cavity from the water inlet channel 6. While providing a fixed position for the one-way valve, the water inlet channel 6 also has the effect of preventing gas from overflowing from the rotatable circular shell. The gas pressure inside the outer shell 12 increases rapidly. The cross-section of the prefabricated groove 4 is triangular, which is convenient for generating gas to separate and break the outer shell 12 along the groove. After the outer shell 12 is separated, the sonar system 7 sends a signal again, and the trigger 8 activates the energetic material 9 to disperse the inner shell, and generates high-pressure bubbles to swallow the gas mass generated by the gas-producing material 10, so that the pulsating energy of the bubbles is enhanced and the jet load is increased.

[0055] The sensors, controllers, and control programs that may be involved in the above description are all prior arts and will not be elaborated here.

[0056] The embodiments of the present invention disclosed above are only used to help explain the present invention. The embodiments do not describe all the details in detail, nor limit the invention to the specific embodiments described. According to the content of this specification, many modifications and changes can be made. These embodiments are selected and specifically described in this specification to better explain the principle and practical application of the present invention, so that those skilled in the art can understand and utilize the present invention well.
