A window breaking device for underwater rescue comprises an energy storage device body, a main support, a main support handle, a suction cup, a corrugated pipe, a waterproof film, an alloy conical head and an auxiliary support. A main support is arranged on the side face of the energy storage device body, a sealing cap is arranged at the top of the energy storage device body, and the sealing cap seals the upper end of the energy storage device body. A sealing ring is arranged at the lower end of the accumulator body; a corrugated pipe is arranged below the sealing ring, and a suction cup head is arranged below the corrugated pipe. The sucker head and the sucker are integrated, and the waterproof film seals the through hole of the energy storage ring to prevent a water source from entering; a long through hole is formed in the main support, a main support sliding groove is formed in the side face of the main support, a main support handle is arranged on the main support, the upper end of the spring ring is placed in a concave hole in the tail end of the main support handle, and the lower end of the spring ring is placed in a concave hole in the tail end of the auxiliary support handle. Through cooperative use of the energy storage device main body, the strong spring and the suction cup, a rescue worker can operate the device with one hand to adsorb a glass-toughened glass window underwater and rapidly crush the glass-toughened glass window.

An underwater salvage window breaking device comprises an energy storage device body, a conical head, a rotary disc and a suction cup. The underwater salvage window breaking device is characterized in that a handle and a ferrule are arranged above the device body, and the suction cup is arranged below the device body; a fixing ring is arranged on the side face, an inner cavity is formed in the device body, and a small fixing frame, a large fixing frame, a limiting elastic piece, a spring piece and a through hole are arranged at the bottom of the inner cavity. The large fixing frame is provided with a limiting elastic piece and is rotationally connected with one end of the driving shaft. A turntable, a small coil spring and a driving gear are arranged on the driving shaft; the other end of the driving shaft is rotationally connected with a waterproof bearing which is fixed to the side face of the device body. The small coil spring always drives the turntable to retract the pull wire towards the interior of the device main body until the bracelet is blocked by the rubber sleeve under the condition that the pull wire is pulled outwards without external force; the adsorption glass-toughened glass window can be operated by a single hand under water and can be quickly crushed.

The utility model discloses a long -acting anti -block filter device relates to agricultural irrigation technical field, including the water tank, the water tank one side is connected with the water inlet pipe, the water tank opposite side is connected with the water delivery pipe, the inside of water tank is provided with the stirring broken subassembly, the water delivery pipe one end is connected with the connecting pipe, the inside of connecting pipe is provided with the filter drum, the utility model discloses beneficial effect is: the filter drum adopts 304 stainless steel and constitutes, and this material is firm and durable, corrosion -resistant, can adapt to various complex water quality environment, can prolong the service life of filter drum, at the same time, the filter drum inner wall is connected with the plug tube and the sleeve pipe cooperation, the sleeve pipe inner wall fixed three sets of sealing rings, not only guarantee the leakproofness of connection, prevent water leakage, still can block the impurity and enter the connecting pipe inside to a certain extent, reduce the accumulation of impurities at the connecting pipe, reduced the risk of blockage.

This utility model relates to the technical field of sealed chambers, and in particular to a deep-sea environment training sealed chamber, including a base, a sealed chamber fixedly installed on the upper surface of the base, a sealing cover fixedly installed on the right end of the sealed chamber, an observation window fixedly installed on the front end of the sealed chamber, a pressure control machine fixedly installed on the upper surface of the base, a flange fixedly installed on the right end of the pressure control machine, an air pipe provided at the front end of the sealed chamber, and a water outlet pipe fixedly installed on the front surface of the sealed chamber. A cam-linkage linkage locking mechanism is used, where rotating the handle drives the cam to quickly engage the sealing cover, shortening the opening and closing time of the chamber door. Combined with the pressure self-tightening effect of the fluororubber sealing ring, the high-pressure leakage rate is reduced, completely solving the problem of sealing failure caused by uneven bolt stress. A tungsten carbide window breaker and a polycarbonate plexiglass cover are integrated at the rear end of the sealing cover, allowing for rapid shattering of the glass cover in emergencies.
