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 present invention discloses a cannon using hydraulic-electric power for launching, and belongs to the field of artillery technology. The present invention symmetrically and fixedly installs hydraulic-electric effect generators at the starting end of the barrel and on both sides of the barrel in the extending direction. The launching load is loaded into the barrel before launching, and a high-voltage and high-power pulse current is used to induce the instantaneous and violent vaporization of the liquid in the hydraulic-electric effect generator to form a high-speed shock wave with a pressure of hundreds of megapascals or more, which is transmitted to the barrel through the opening end of the hydraulic-electric effect generator tube body, and the launching load in the barrel is pushed to accelerate along the extending direction of the barrel. The hydraulic-electric effect generators on both sides of the barrel are excited in turn, and the high-speed jet generated just acts on the rear end of the launching load, driving the launching load to continuously accelerate in the barrel. The present invention has the advantages of fast and continuous launching, high initial launching velocity, adjustable launching velocity, low unit launching energy cost, no high-temperature flame leakage and ablation, and long barrel service life.

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 invention discloses a double-bin filler selectable supply method, and relates to the technical field of filler launching, according to the double-bin filler selectable supply method provided by the invention, through a multi-bin structure and a parallel processing mechanism, the cycle time of filler launching is remarkably shortened, the overall launching speed is increased, and the service life of the filler is prolonged. Rapid selection and efficient emission of various types of fillers are realized, so that diversified requirements in a complex working environment are met; rapid switching of multiple species is supported, and system shutdown and manual adjustment time caused by replacement of filler types are reduced; the pushing mechanism and the launching mechanism are matched with each other to achieve two-stage launching of the filler, so that the device is compact and small in design, the length of the electric cylinder is effectively reduced, the power of the pushing mechanism is smaller than that of the launching mechanism, the pushing mechanism and the launching mechanism are matched to conduct stage type filler launching, and the power of the whole machine can be effectively reduced.

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.
