Rocket type catching net launching device
ActiveCN222544557Ueasy accesslow costDefence devicesCompressed gas gunsGas cylinderStructural engineering
The utility model discloses a rocket type catching net launching device which comprises gun barrels, gas bombs, a percussion mechanism, a catching net, a cartridge receiver and a folding telescopic rod, the gas bombs are arranged in the corresponding gun barrels, the percussion mechanism is arranged at the tail ends of the gun barrels, the catching net is connected with the gas bombs, and a fixing part is fixedly installed at the front end of an inner cavity of the cartridge receiver. The tail end of the gun barrel is detachably installed on the front side of the fixing component, and the folding telescopic rod is arranged at the front end of the gun barrel. The high-pressure gas cylinder is adopted as launching power, compared with power sources such as ammunition and fuel, higher safety is achieved, materials are easy to obtain, cost is lower, the unfolding angle of the gun barrel can be freely adjusted according to actual requirements, the larger the unfolding angle is, the higher the unfolding speed of the catching net is, and the closer the flying distance is. The method is suitable for close-range combat; otherwise, the smaller the unfolding angle is, the slower the unfolding speed of the catching net is, the farther the flying distance is, and the catching net is suitable for long-distance combat.

Auxiliary sand cleaning device and method for sand core forming
ActiveCN119500994AResidue reductionemission reductionMoulding machine componentsMoulding machinesCantilevered beamMechanical engineering
The invention relates to an auxiliary sand cleaning device and method for sand core forming. The device comprises a fixed part, a rotating part and a flapping part. The fixing part comprises a connecting frame, and a rotary driving piece is arranged on the connecting frame; the rotating part comprises a cantilever beam, one end of the cantilever beam is connected with the output end of the rotating driving piece, and the other end is connected with the flapping part; the flapping part comprises a floating mechanism and a floating plate; the floating mechanism provides elastic restoring force for the floating plate, so that the floating plate can float relative to the cantilever beam after being subjected to external force; the area of the floating plate is larger than that of a sand shooting opening of the core making mold; in the working process, the connecting frame is used for being connected with sand shooting equipment, the rotating driving piece is used for providing rotating torque, the cantilever beam is used for converting the rotating torque into beating motion of the beating part, and therefore the floating plate can be aligned with a sand shooting opening for repeated beating. Uncured precoated sand in the sand core can be removed to the maximum extent, and the sand discharging effect is improved.

Air storage type air gun
The utility model discloses an air storage type air gun, and particularly relates to the technical field of air guns, the air storage type air gun comprises a gun body, bullets and a gun stock fixedly installed on one side of the gun body, a shock absorption box is fixedly installed on one side of the outer surface of the gun stock, a shock absorption air bag is fixedly installed in the shock absorption box, and a rubber pad is slidably connected in the shock absorption box. And the rubber pad is fixedly connected with the outer surface of the damping air bag. According to the air storage type air gun, in actual work, an operator exerts pushing force on the pressing plate, the piston rod pushes the piston to move towards the interior of the air conveying cylinder, the damping air bag is expanded, and the rubber pad is pushed to the exterior of the damping box and makes contact with the body of the operator; the recoil force generated by shot shooting enables the gun stock to push the damping box to move towards an operator, then the damping air bag and the rubber pad are extruded, the recoil force acting on the body of the operator can be effectively reduced through the damping air bag and the rubber pad, and damage to the body of the operator caused by the recoil force is effectively reduced.

Underwater facility generative cavitation cleaning method and system based on diffusion model
The application belongs to the technical field of underwater operation and maintenance process, and discloses an underwater facility generative cavitation cleaning method and system based on a diffusion model. The method comprises the following steps: obtaining sonar images, body attitudes and water depth data of the underwater facility; inputting the data into a conditional diffusion model to obtain a cooperative control action sequence, wherein the sequence comprises propeller thrust instructions and cavitation jet instructions, and the feedforward compensation thrust in the thrust instructions is ahead of the jet opening instruction in time; first, the propeller is controlled to output compensation thrust according to the feedforward compensation thrust instruction, and then the cavitation jet device is controlled to be opened; during the jet process, the real-time output thrust of the propeller is monitored, and if it is less than the recoil force estimated according to the current jet parameter, the jet parameter is reduced. The above-mentioned method generates cooperative sequence actions through a diffusion model, combines feedforward thrust pre-compensation and closed-loop safety clamping, realizes active inhibition of recoil force and self-adaptive cleaning of materials, and effectively improves the stability of underwater operation and the cleaning quality.
