Description

Technical Field

[0001] This utility model belongs to the technical field of water storage tanks, and specifically relates to a special water storage tank for high-pressure fine water mist. Background Technique

[0002] "Fine water mist" is a concept relative to "water spray". The so-called fine water mist is water particles generated by high-pressure water spraying using a special nozzle. In NFPA750, the definition of fine water mist is: on a plane 1 meter away from the nozzle under the minimum design working pressure, the diameter Dv0.99 of the thickest part of the water mist is not greater than 1000 μ. According to the size of the water particles in the water mist, the fine water mist is divided into 3 levels.

[0003] Currently, for mobile high-pressure fine water mist fire extinguishing devices, the sizes of the water storage tanks used are fixed, which restricts the flexibility of their water storage capacity to a certain extent. In the face of large-scale fires or occasions that require long-term continuous fire extinguishing, the limited water storage capacity may affect the persistence and thoroughness of the fire extinguishing effect, and may also bring great pressure and risks to rescue personnel. Content of the Utility Model

[0004] The purpose of this utility model is to provide a special water storage tank for high-pressure fine water mist, which can adjust the capacity of the water storage tank composed of the first box body and the second box body. When more water is needed, the water storage tank can be unfolded or extended; when the water demand is less, it can be folded or shortened to save space, so that the water storage tank can better adapt to the challenges of different scenarios and requirements, and provide more comprehensive and efficient support for fire fighting work.

[0005] The technical solution adopted by this utility model is specifically as follows:

[0006] A special water storage tank for high-pressure fine water mist, including a first box body. Both sides of the first box body are provided with second box bodies. One side of the second box body and inside the first box body, there is a fixed sliding ring that is hermetically and slidably connected to the inner wall of the first box body. Sealed annular grooves are arranged on both sides of the first box body. The inner wall of the sealed annular groove is fixed with a limiting sliding ring that is hermetically and slidably connected to the second box body through bolts. One side of the first box body is provided with a double-headed motor. Both ends of the output shaft of the double-headed motor are fixed with lead screws. L-shaped moving blocks are arranged on the outer walls of the two lead screws. Plug-in grooves are opened on both sides of the first box body. Plug-in rods fixed to the second box body are inserted into the internal of the plug-in grooves. Two limiting sliding grooves respectively communicated with the plug-in grooves are opened on one side of the first box body. L-shaped moving blocks respectively threadedly connected to the two lead screws are slidably installed in the two limiting sliding grooves. One side of the L-shaped moving block passes through the limiting sliding groove and is fixed to the plug-in rod. A guide rod is fixed to the outer wall of the second box body. A guide groove slidably connected to the guide rod is opened on the outer wall of the first box body. A water inlet pipe is fixedly penetrated through the top wall in the middle of the first box body. A water outlet pipe is fixedly penetrated through the bottom wall in the middle of the first box body.

[0007] Further, the cross-section of the first box body is a box body with a square outside and a circular inside and openings are arranged on both sides. The second box body is a box body with a circular cross-section and an opening on one side.

[0008] Further, a sealing ring in contact with the limiting sliding ring is arranged inside the sealed annular groove.

[0009] Further, a liquid level sensor is arranged on the inner bottom wall in the middle of the first box body. A display screen electrically connected to the liquid level sensor is arranged on one side of the first box body.

[0010] Further, L-shaped support feet are fixed on the four corners of the bottom of the first box body. The L-shaped support feet are composed of a vertical plate and a horizontal plate. Fixing grooves are penetrated and opened on the outer wall of the horizontal plate.

[0011] Further, a sewage pipe is fixedly penetrated through the bottom wall in the middle of the first box body and on the side where the water outlet pipe is arranged. A valve is arranged on the outer wall of the sewage pipe.

[0012] The technical effects obtained by this utility model are:

[0013] A special water storage tank for high-pressure fine water mist of the present utility model is provided with a first box body and two second box bodies that cooperate with each other. The two lead screws are driven to rotate by a double-headed motor. The spiral directions of the threads on the two lead screws are opposite, driving the two L-shaped moving blocks to move relatively. The L-shaped moving block drives the insertion rod to move, and the insertion rod drives the second box body to move, so that the two second box bodies move relatively, thereby adjusting the capacity of the water storage tank composed of the first box body and the second box body, improving the flexibility of the water storage tank in use. When more water is needed, the water storage tank can be expanded or extended; when the water demand is small, it can be folded or shortened to save space, enabling the water storage tank to better adapt to the challenges of different scenarios and needs, and providing more comprehensive and efficient support for fire protection work.
