Embodiment Construction

[0041] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] A gas ejection test device, including a water storage device, a power device and a locking mechanism, such as figure 1 shown;

[0043] The water storage device is a cuboid water storage tank 10, the upper and lower sides are 40mm thick iron plates, one side of the side is made of the same material as the upper and lower sides, the thickness is 20mm, and the upper half has a groove, and the bottom has a water discharge valve. It is convenient to change the water quality; the other three sides are transparent plexiglass, which is convenient for observing the internal experimental conditions, such as figure 1 , figure 2 shown;

[0044] The power unit includes a buckle 1, a power spring 2, a car body 3, a slide rail 4, a locking link 6 and a transmission link 7, such as figure 1 , image 3 shown;

[0045] The buckle 1 ...

Abstract

The invention relates to a gas ejection test apparatus, and belongs to the technical field of ships, underwater navigation vehicle engineering, and water conservancy and hydroelectric engineering. The gas ejection test apparatus comprises a water storage apparatus, a power apparatus and a locking mechanism. The power apparatus and the locking mechanism are fixedly connected to a metal plate of a side surface of a water storage tank. The locking mechanism is arranged below the power apparatus. A locking wrench locks a vehicle body to the bottom of a slide rail through starting a baffle plate. A water drain valve is closed and water is injected into the water storage tank. The vehicle body is pulled to move downwards, and the locking wrench locks the vehicle body to the bottom of the slide rail. After the water surface calms, ventilation is carried out on an experiment model through a locking connecting rod and a transmission connecting rod. The locking wrench is pulled, so that a spring contracts, and the vehicle body is driven to move upwards. The experiment model is further driven by the transmission connecting rod to yield water, and works such as experiment observation and data measurement are simultaneously carried out. According to the gas ejection test apparatus of the invention, model experiment research can be carried out on a phase of underwater motions and a phase of crossing water surface of a navigation body, so that water yielding experiment problems are solved.

Description

technical field [0001] The invention relates to a gas ejection test device, which belongs to the technical fields of ship and underwater vehicle engineering and water conservancy and hydropower engineering. Background technique [0002] In modern naval warfare, more and more attention is paid to the precise strike against the enemy and the stealth protection of oneself. The underwater launch vehicle has unique advantages in these two aspects, so it has been paid more and more attention. However, when the submarine-launched vehicle sails at high speed near the water surface or crosses the water surface, due to the significant effect of the water surface effect and the sudden change in the density of the fluid medium, it will cause a sharp change in the mechanical environment of the vehicle. A considerable disturbance will affect the attitude of the vehicle out of the water, produce severe shock and vibration, and even lead to the destruction of the structure of the vehicle an...
