Description

Technical Field

[0001] The invention belongs to the field of water-emergence experiments of a cross-medium water-emergence vehicle model, and in particular relates to a power device for adjusting the exit speed of a vehicle from a tube. Background Art

[0002] A vehicle's emergence from the water is typically powered by its own power or external power. External power offers advantages over its own power, such as stable pressure and the absence of thermal protection. Depending on the type of power source, external power can be broadly categorized as high-pressure gas, hydraulic, and electromagnetic. High-pressure gas, compared to other methods, offers advantages such as high energy, ease of use, and simplified maintenance, meeting the complex operating conditions of a vehicle's emergence from the water. Because the entire process from launch to full emergence from the water is subject to complex environmental changes and hydrodynamic loads, the propulsion system must be safe, reliable, stable, and airtight. However, the instantaneous energy released by high-pressure gas propulsion systems is extremely high, placing significant strain on their structural strength, stability, safety, and airtightness. Furthermore, due to the varying requirements of the vehicle's emergence from the water, adjustments to the relevant components of the propulsion system are often required to achieve varying velocity. These requirements are difficult to achieve with traditional high-pressure gas propulsion systems.

[0003] The patent with publication number CN118670200A discloses a gas-powered device for use in water-borne vehicles. The device is a type of high-temperature and high-pressure gas. The device can realize the ejection of the vehicle out of the water, but the cross-sectional area of the high-pressure gas outlet is fixed, and the outlet gas flow, pressure, and speed cannot be continuously adjusted over a large range. It also cannot realize the adjustment of the vehicle's exit speed, nor can it be used in a negative pressure environment, and cannot meet the requirements of complex working conditions of the vehicle exiting the water experiment. Summary of the Invention

[0004] In view of this, the present invention aims to propose a power device for adjusting the speed of the vehicle exiting the tube, so as to solve the problem that the speed of the vehicle exiting the tube is difficult to adjust. The device can be used in a negative pressure environment.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a power device for adjusting the speed of a navigation body exiting the barrel, comprising:

[0007] The nozzle is detachably connected to the outlet end of the shell assembly and communicates with the high-pressure gas cavity through the auxiliary gas release assembly. High-temperature and high-pressure gas is released by adjusting the nozzles with different masses of propellants and different structural parameters.

[0008] Furthermore, the housing component is provided with an injection port communicating with the high-pressure air cavity, and the injection port is provided with a blocking component for closing the injection port.

[0009] Furthermore, the sealing assembly includes a screw plug and a plug, the plug is used to seal the injection port, and the screw plug is connected to the injection port to fix the plug.

[0010] Furthermore, the shell assembly includes a front head and a rear head, and the front head and the rear head are connected to form a cavity for accommodating the high-pressure gas cavity and the auxiliary gas release assembly.

[0011] Furthermore, the front head and the rear head are sealed and connected via a first O-ring.

[0012] Furthermore, a sensor mounting base is provided on the front head for mounting a pressure sensor for detecting the gas pressure in the high-pressure gas cavity.

[0013] Furthermore, the auxiliary gas release component is a baffle, and a number of semicircular through holes are axially penetrated on the peripheral wall of the baffle, and pressure-bearing ports for bearing energy impact are penetrated on the end faces on both sides, wherein the cross-sectional shape of the pressure-bearing port is a circular hole, and a plurality of strip grooves integral with the circular hole are arranged along the circumference of the circular hole.

[0014] Furthermore, a baffle ring is provided between the baffle and the high-pressure air cavity.

[0015] Furthermore, a shock-absorbing pad is provided between the high-pressure air cavity and the inner wall of the housing assembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This propulsion system allows for continuous adjustment of the vehicle's exit velocity over a wide range under negative pressure conditions. High-temperature, high-pressure gas generated during the vehicle's water exit test propels the vehicle upward. By changing nozzles with varying diameters, the vehicle's exit velocity can be continuously fine-tuned. By adjusting the propellant mass, the velocity can be adjusted over a wide range.

Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0029] Referring to the accompanying drawings, this embodiment is described, which includes a power device for adjusting the speed of a vehicle exiting the barrel, comprising:

[0030] The outer shell assembly has a high-pressure gas chamber 6 for storing high-temperature and high-pressure gas and an auxiliary gas release assembly for assisting the release of high-temperature and high-pressure gas, which are detachably connected in sequence along the axial direction; specifically, the outer shell assembly includes a front head 1 and a rear head 2, which form a cavity for accommodating the high-pressure gas chamber 6 and the auxiliary gas release assembly after being connected. The front head 1 and the rear head 2 are the base of the entire power device, both made of high-strength materials. The joint surface between the two has a groove for accommodating the first O-ring 9. The front head 1 and the rear head 2 are sealed and connected by the first O-ring 9. The setting of the first O-ring 9 can ensure airtightness in a negative pressure environment, so that the device can be used in a negative pressure environment. The front head 1 and the rear head 2 are connected by a number of high-strength bolt sets 10 evenly distributed on the circumference. The high-strength bolt set 10 specifically includes bolts, nuts, spring washers and flat washers, which can ensure a tight connection. The outer shell assembly adopts a split setting and is installed by the high-strength bolt set 10, which can achieve a detachable connection. This provides a convenient prerequisite for subsequent replacement of propellants 20 of different masses and nozzles 11 of different parameters.

[0031] The nozzle 11 is detachably connected to the outlet end of the outer shell assembly and communicates with the high-pressure gas chamber 6 via the auxiliary gas release assembly. High-temperature, high-pressure gas is released by adjusting the propellant 20 of different masses and the nozzle 11 with different structural parameters. Specifically, by replacing nozzles 11 with different throat diameters, the flow rate, pressure, and speed of the gas at the outlet of the power unit can be continuously adjusted. By adjusting the mass of the propellant 20, the energy of the stored high-temperature, high-pressure gas can be adjusted, thereby achieving a wide range of continuous control of the vehicle's exit speed. The nozzle 11 and the outer shell assembly can be connected in a detachable manner, such as a threaded connection, which must meet structural strength and usage requirements.

[0032] In this embodiment, an injection port connected to the high-pressure air cavity 6 is provided on the shell component, and the injection port is provided with a sealing component for closing the injection port. Specifically, the sealing component includes a plug 3 and a plug 4, the plug 4 is used to seal the injection port, and the plug 3 is connected to the injection port to fix the plug 4. For the high-pressure air cavity 6, a corresponding opening is provided near the injection port. One end of the plug 4 needs to be inserted into the corresponding opening during installation to ensure the sealing of the high-pressure air cavity 6. After the gas is injected through the plug 4, the injection port is threadedly connected to the injection port through the plug 3 to complete the closure of the injection port. The other side of the high-pressure air cavity 6 is open for effectively releasing high-temperature, high-pressure gas. By replacing propellants 20 of different masses, the gas pressure can be adjusted, thereby adjusting the motion parameters of the navigation body.

[0033] In this embodiment, a sensor mounting base 14 is provided on the front end 1 for mounting a pressure sensor for detecting the gas pressure within the high-pressure gas chamber 6, thereby measuring the pressure of the high-pressure gas. The pressure sensor is specifically connected to the controller. The specific connection method and control program can be specifically configured according to the actual control and feedback logic. Existing technologies are used and will not be described in detail.

[0034] In this embodiment, the auxiliary gas release component is a baffle 8, and a plurality of semicircular through holes are provided axially through the peripheral wall of the baffle 8. This structural form can ensure the full release of the energy of the high-temperature and high-pressure gas. Pressure-bearing ports for withstanding energy impact are provided through the end faces on both sides. The cross-sectional shape of the pressure-bearing ports is a circular hole, and a plurality of strip grooves integral with the circular hole are arranged along the circumference of the circular hole. With this cross-sectional shape, the baffle 8 can withstand the huge energy impact when the high-temperature and high-pressure gas is released. The material of the baffle 8 has high strength and is reusable. The lower surface of the baffle 8 is a plurality of inclined legs that can fit tightly with the conical surface of the rear head, which is conducive to the fixation of the high-pressure gas chamber 6. The setting of the baffle 8 can cooperate with the outer shell assembly to complete the fixation of the high-pressure gas chamber 6. A shock-absorbing pad 5 is provided between the high-pressure gas chamber 6 and the inner wall of the outer shell assembly. The shock-absorbing pad 5 can effectively isolate the instantaneous impact occurring during the launch process, protect the front head 1, avoid damage to parts due to rigid collision, and prevent excessive wear between the high-pressure gas chamber 6 and the outer shell assembly. The material of the shock-absorbing pad 5 is reasonably set according to needs and needs to meet the requirements of strength, flexibility and high temperature resistance.

[0035] In this embodiment, a retaining ring 7 is provided between the baffle 8 and the high-pressure gas cavity 6. The retaining ring 7 can fix the high-pressure gas cavity 6 and can also fit the high-pressure gas cavity 6 and the baffle 8 tightly without leaving any gaps, thereby reducing the instantaneous impact when the high-temperature and high-pressure gas is released and avoiding damage to parts.

[0036] In this embodiment, a second O-ring 12 and a polytetrafluoroethylene gasket 13 are provided on the end face of the housing assembly where the nozzle 11 is located. The polytetrafluoroethylene gasket 13 is provided to seal the nozzle 11. During the water discharge experiment, the propellant 20 placed in the high-pressure gas chamber 6 is triggered by an external control system via a metal wire. The two ends of the metal wire are connected to the propellant 20 and the control system respectively, and the middle portion passes through the hole of the plug 4 and the screw 3. The high-temperature and high-pressure gas generated by the triggering passes through the nozzle and penetrates the polytetrafluoroethylene gasket, propelling the vehicle upward.

[0037] All parts of this device are made of high-strength materials to meet the high-intensity impact requirements of the instantaneous release of high-temperature and high-pressure gas.

[0038] When in use, first install the nozzle 11 and the second O-ring 12 under the rear head 2, then install the baffle 8, the retaining ring 7, the high-pressure air chamber 6, and the shock-absorbing pad 5 into the rear head 2 in sequence, and then use the high-strength bolt set 10 to tighten the front head 1 and the rear head 2. At this time, the power unit 15 has been assembled. Then install the navigation body 17 into the cylinder 16. First, install the sealing ring 18 on the navigation body 17. There are reserved bolt holes on the side of the navigation body 17. The sealing ring 18 can be fixed with small bolts to ensure that the sealing ring 18 does not get out of place when the navigation body 17 moves in the cylinder 16. The navigation body has a hoisting hole. The navigation body 17 can be installed in the cylinder 16 by hoisting, and a film 19 is glued to the top of the cylinder 16. After placing the navigation body 17 into the cylinder 16, place a polytetrafluoroethylene pad 13 under the rear head 2 of the power unit 15, then install it on the cylinder 16 and connect it through the high-strength bolt set 10. After the connection is completed, the navigation body 17 water exit test can be carried out. The polytetrafluoroethylene pad 13 can be selected from other types of gaskets according to actual needs. Materials that can play a sealing role in the early stage and disappear under the action of high-temperature and high-pressure gas in the later stage are all within the spirit of the invention of this application. By adjusting the nozzles 11 of different throat diameters and the propellants 20 of different masses, a large range of continuous adjustment of the navigation body's exit speed can be achieved, thereby meeting the various complex working conditions of the navigation body water exit model experiment, which has high practical engineering significance.
