This invention discloses a high-speed parallel water entry experimental launching device and method for a vehicle, belonging to the field of hydrodynamic experiments. It includes a supporting base, a parallel controller, a parallel launching assembly, and a power unit. The parallel launching assembly is mounted on the supporting base via the parallel controller, and the power unit provides launching power and adjusts the water entry velocity. The parallel launching assembly includes a first launching device and a second launching device arranged side-by-side, enabling parallel launching of two projectiles and adjustment of the launching angle. The parallel controller includes a parallel control mechanism and a spacing adjustment mechanism. The parallel control mechanism ensures the relative parallelism of the first and second launching devices, while the spacing adjustment mechanism adjusts the launching distance between the first and second launching devices. This invention has a simple and practical structure, is easy to assemble, has high reliability and durability, and exhibits good repeatability and safety, providing experimental assurance for studying the hydrodynamic characteristics of structures at the moment of water entry.

The utility model relates to the technical field of water tank filters, and particularly discloses a high-efficiency water tank filter capable of discharging water in a vortex manner, which comprises a water tank shell, the filtering mechanism is arranged in the water tank shell, the filtering mechanism comprises a lower water tank, a spiral plate and a plurality of filtering hole grooves, the spiral plate is fixedly connected to the top end of the lower water tank, the filtering hole grooves are formed in the outer side wall of the lower water tank, and a mounting seat is fixedly connected to the top end of the lower water tank; the pressing plate is mounted at the top end of the filtering mechanism; through the arrangement of the water discharging groove, the spiral plate, the filtering hole groove and the mounting base, in the water discharging process, due to the fact that the spiral plate is arranged on the water discharging groove, water flow can flow in a vortex shape in the water discharging groove, the vortex water discharging mode not only improves the water discharging speed, but also increases the washing area between the water flow and the filtering hole groove, and therefore the water discharging effect is improved. Therefore, the filtering effect is obviously improved.

The application provides a launching device, belonging to the field of projectile launching devices. The launching device comprises a cylinder, a gas pressure cavity is formed in the cylinder; an air inlet hole and an air outlet hole, both of which are formed on the cylinder; a launching tube, which is arranged on the cylinder and is in communication with the gas pressure cavity through the air outlet hole; an opening and closing valve core, which is located in the cylinder and is slidingly installed in the cylinder, the opening and closing valve core opens and closes the air outlet hole, and the sliding direction of the opening and closing valve core is parallel to the axis direction of the launching tube; and an opening and closing assembly, which comprises an unlocking jacking rod, the unlocking jacking rod is slidingly installed in the launching tube, the sliding direction of the unlocking jacking rod is parallel to the axis direction of the launching tube, and the unlocking jacking rod slides and pushes the opening and closing valve core to open the air outlet hole. The opening and closing valve core arranged in the application can make the gas pressure cavity in a sealed state, when the projectile needs to be launched, the unlocking jacking rod is slid and the opening and closing valve core is pushed to open the air outlet hole, and the high-pressure gas in the gas pressure cavity can launch the projectile.
