5results about How to "Avoid explosive situations" patented technology

The application provides a gas conveying pipeline fine water mist explosion-proof device, which comprises a long pipe, a plurality of atomizing nozzles, a communicating cavity arranged in the long pipe, a water pipe communicated with one end of the communicating cavity, and a drainage cleaning mechanism arranged on the arc surface of the long pipe. The drainage cleaning mechanism comprises a leakage hole, a cylinder and a fan blade assembly. The leakage hole is arranged on the arc surface of the long pipe, the cylinder is inserted into the leakage hole, and the fan blade assembly is arranged in the cylinder. The arc surface of the long pipe is provided with a square hole. The gas in the pipeline is sprayed by the atomizing nozzles, so that the concentration of the gas is reduced, and the gas explosion is prevented to a certain extent. The water in the pipeline is discharged through the cylinder and the leakage hole, so that the rusting of the pipeline caused by excessive water in the pipeline is avoided.

This invention relates to the field of lithium battery pack technology and discloses a lithium battery pack with multiple protection functions, including a bottom shell and a top shell. The bottom of the top shell abuts against the bottom shell. An installation groove is formed inside the top shell, and a temperature sensor and a pressure sensor are fixedly connected inside the installation groove. A fire detector is fixedly connected inside the bottom shell. By activating a first suction fan, hot air inside the bottom and top shells can be discharged to prevent the heat inside the bottom and top shells from damaging the operation of the lithium battery pack. Activating a second suction fan can draw cold air from outside into the bottom and top shells to cool the inside of the bottom and top shells. At the same time, the circulation of coolant carries away the heat of the lithium battery pack itself, which can quickly dissipate heat from the lithium battery pack and effectively prevent heat damage to the lithium battery pack. It also prevents the lithium battery pack from short-circuiting due to heat, thus effectively protecting the lithium battery pack.

This utility model discloses a steam generator with a pressure relief structure and a household appliance. The steam generator with a pressure relief structure includes: a flow channel plate, which has an opening, a first water inlet, a steam outlet, and a connecting port, and a flow channel is provided inside the flow channel plate; a heating plate, including a plate body and a heating element disposed on one side of the plate body, with the side of the plate body opposite to the heating element covered by the opening; and a pressure relief structure connected to the flow channel plate, which has a pressure relief port connected to the connecting port. The steam generator with a pressure relief structure in this utility model, by setting the pressure relief structure, can discharge excessively high-pressure steam, ensuring safe use.

The utility model discloses a two-way charging energy storage device, which comprises a charging energy storage device shell and a heat dissipation mechanism, an insulation mechanism is connected above the outer wall of the charging energy storage device shell, an access mechanism is fixedly installed above the outer wall of the insulation mechanism, the heat dissipation mechanism is fixedly installed below the outer wall of the charging energy storage device shell, and the heat dissipation mechanism is fixedly installed below the outer wall of the charging energy storage device shell. And an explosion-proof mechanism is fixedly mounted on the outer surface of the charging energy storage device shell. According to the two-way charging energy storage device, the access mechanism is arranged, and the insulation mechanism is arranged in a matched manner, so that stable access can be realized when the charging energy storage device performs charging access, and insulation protection can be performed on the access position.

The utility model belongs to the technical field of fireproof valves, and particularly relates to a fireproof valve capable of blocking smoke diffusion, which comprises a fireproof valve body, an opening is arranged on the fireproof valve body, a blocking plate is arranged in the opening, four corners of the bottom of the blocking plate are fixedly connected with fixing blocks, cavities are arranged in the fixing blocks, limiting blocks are arranged in the cavities, and the limiting blocks are fixedly connected with the opening. The edge of the limiting block is slidably connected with the inner side wall of the cavity, a clamping block is fixedly connected to one side of the limiting block, a clamping groove corresponding to the clamping block is formed in the fireproof valve body, a limiting rod is fixedly connected to the side, away from the clamping block, of the limiting block, and one end of the limiting rod penetrates through the inner side wall of the cavity and extends outwards. The extending end of the limiting rod is fixedly connected with a limiting handle. The fireproof valve capable of obstructing smoke diffusion can obstruct smoke diffusion and is convenient to mount and dismount, convenience of regular cleaning is achieved, and the situation that dust explodes due to dust accumulation is avoided.
