Description

Technical Field

[0001] This invention relates to the field of underwater launch experiment technology for aircraft, and more particularly to a comprehensive experimental water tank system for simulating the launch of an aircraft from the water in a polar environment. Background Technology

[0002] Although the melting of Arctic glaciers is extremely detrimental to the global climate, these changes provide natural conditions for the opening of Arctic shipping routes, which will help improve the convenience of global shipping.

[0003] In the development of polar equipment, the technology for underwater vehicles to break ice and emerge from the water is a crucial one. However, my country is far from the Arctic, and conducting actual ship trials is costly and involves many uncontrollable factors. Therefore, there is an urgent need for a comprehensive experimental water tank system that can simulate the icebreaking process of vehicles emerging from the water in a polar environment.

[0004] Given the current technological and research background, multiple experimental devices for simulating the emergence of a vehicle from the water have been built. However, comparative analysis has revealed that existing experimental devices for simulating the emergence of a vehicle from the water cannot simulate the complex polar ice layers, ocean waves, and low-temperature environment, nor can they simulate the movement of the vehicle carrying the vehicle. Most importantly, existing experimental devices cannot simulate decompression environments, and therefore cannot accurately simulate similar flow problems during the emergence of a vehicle from the water.

[0005] To address the aforementioned problem of simulating the polar environment of a vehicle emerging from the water and breaking through ice, a comprehensive experimental water tank system design for simulating the polar environment has been invented. This comprehensive experimental water tank system can simulate the complex polar environment of ice cover, low temperature, and ocean waves, and also has the ability to simulate complex underwater launch conditions.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0063] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0064] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0065] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0066] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0067] This invention provides a comprehensive experimental water tank system for simulating the water exit of a vehicle in a polar environment. The system consists of a water tank body 1, a refrigeration system, an ice-fixing system 7, a pressure reduction system, a wave-generating and wave-dissipating system 2, a launch and motion simulation system, a lifting system 8, an arresting system 6, an auxiliary mechanical system 9, and a staircase system 10.

[0068] The main body 1 of the water tank is a rectangular steel structure box. Special reinforcing ribs 1-1 are installed on the exterior of the main body 1 to ensure strength under negative pressure conditions. Insulation panels are laid on the walls of the main body 1 for heat insulation inside and outside the tank. Two elliptical glass windows 1-10 are provided on the front of the main body 1 for observing experimental phenomena. A hatch 1-14 is located on the top of the main body 1, through which equipment is hoisted. An airtight door 1-3 is opened on the right side of the main body 1 for personnel access. Inlet and outlet water pipes and pressure-reducing exhaust pipes are located on the front of the main body 1. A through-panel 1-2 is installed above the front wall of the main body 1, with airtight connectors installed on the through-panel 1-2. Cables are threadedly connected to the airtight connectors inside and outside the through-panel 1-2.

[0069] The wave-generating and wave-dissipating system 2 includes a wave-generating system, which consists of a wave-generating float, a slide rail, a slider, a motor, a control system, etc. The entire system is installed on the upper left wall of the pool body 1. The motor drives the slider to move along the slide rail, which in turn drives the float to oscillate, thus realizing the wave-generating function. The control system can control the amplitude and frequency of the float's movement.

[0070] The refrigeration system consists of one refrigeration unit and two air coolers 3-3. The air coolers 3-3 are installed on the upper wall of the water tank body 1 inside the water tank body 1 and are connected to the external refrigeration unit of the water tank body 1 through refrigeration pipes. The refrigeration system is connected to the control console.

[0071] The pressure reduction system consists of three vacuum pumps 3-4. The vacuum pumps 3-4 are connected to the connection port on the wall of the main body of the water tank 1 through pipes. The vacuum system is equipped with a pressure gauge 3-7 and the pressure reduction system is connected to the control console.

[0072] The launch and motion simulation system is divided into two subsystems: launch system 4 and motion simulation system 5. Launch system 4 mainly consists of launch tube 4-2, high-pressure gas cylinder 4-1, angle adjustment module 4-3, etc., while motion simulation system 5 mainly consists of base 5-1, motor, slide table, slide rail, limit switch 5-9, auxiliary devices, etc. Launch system 4 is connected to the slide table of motion simulation system 5 via base 5-1. Motion simulation system 5 provides lateral velocity to launch system 4 to simulate the horizontal movement of the underwater vehicle. Launch system 4 uses compressed air to eject the model out of the tube, accelerating the model.

[0073] The ice-fixing system 7 consists of four ice-fixing mechanisms, with two ice-fixing mechanisms in a group, fixed on both sides of the pool wall respectively. The two ice-fixing mechanisms are connected by an ice-clamping beam, and each ice-fixing mechanism has a rotatable handle.

[0074] The lifting system 8 consists of a platform, slide rail, motor, base, etc. The lifting system 8 is fixed to the end of the slide rail by the base. The launching system 4 moves onto the platform of the lifting system 8. The launching system 4 is fixed to the lifting platform by the fixing devices on both sides. The lifting system 8 lifts the entire launching system 4 above the water surface for model loading.

[0075] The barrier system 6 consists of a net woven with special structural requirements and a truss. The barrier net 6-4 covers the truss, and the truss slides via rails to open and close the barrier net 6-4. The function of the barrier net 6-4 is to block the ejected water model and prevent the projectile from impacting other structures inside the container.

[0076] The auxiliary mechanical system 9 mainly consists of a walkway 9-5, a ladder 9-6, and a motor. The walkway 9-5 is hinged to the side wall of the main body of the water tank 1. When needed, the motor is operated to lower the walkway 9-5, allowing experimenters to perform experiments on it without having to retract it close to the tank wall, thus avoiding interference with experiments and other equipment. The ladder 9-6 is welded inside the main body of the water tank 1, allowing experimenters to descend to the bottom of the main body of the water tank 1 for work.
