A fire extinguishing device that uses water pressure to prevent water from being wasted

Abstract

The present invention relates to the technical field of environment-friendly fire extinguishing equipment, and discloses a fire extinguishing equipment that utilizes water pressure to prevent water from being wasted. , the bottom of the support plate is movably connected with a push rod, the end of the push rod away from the support plate is movably connected with a hollow tube, the end of the hollow tube far away from the push rod is movably connected with a compression spring, and the end of the compression spring far away from the hollow tube is movably connected with a water delivery pipe, The joint between the push rod and the hollow pipe is movably connected with a water inlet plate, the top of the water inlet plate is fixedly connected with a water pressure groove, and the surface of the extension frame is movably connected with a pressure tube, and the inside of the water pressure groove is located on the side of the extension frame. Both sides are fixedly connected with a negative pressure bag. The lateral area of ​​the expansion frame becomes larger and contacts the negative pressure bag, the negative pressure bag is squeezed and the negative pressure space inside is triggered to generate suction force, thus achieving the effect of pumping water after the fire extinguishing is completed to avoid water wastage .

Description

technical field [0001] The invention relates to the technical field of environment-friendly fire extinguishing equipment, in particular to a fire extinguishing equipment that utilizes water pressure to avoid waste of water. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's income, there are more and more electrical equipment in residents' homes. While electrical equipment allows people to enjoy life better, it also indirectly increases the risk of fire. Fire extinguishing water valves are installed next to the street. The existence of fire extinguishing water valves can help firefighters quickly find water sources and quickly extinguish the fire. [0003] However, the existing outdoor fire extinguishing water valves are generally arranged on the edge of the road. This way of setting up will cause pedestrians or vehicles to come into contact with the housing of the fire extinguishing equipment, e...

Problems solved by technology

[0003] However, the existing outdoor fire extinguishing water valves are generally arranged on the edge of the road. This way of setting up will cause pedestrians or vehicles to come into contact with the housing of the fire extinguishing equipment, especially when the lighting conditions are not good, it is easy to cause Three-party loss of personnel, vehicles and fire extinguishing equipment; in addition, the internal water pressure of the existing fire extinguishing equipment is relatively high, and the huge water pressure will not only cause the valve to open for a long time, seriously affecting the progress and timeliness of fire extinguishing, but also It will cause the loss of a large amount of tap water during the fire extinguishing process, so a fire extinguishing equipment that uses water pressure to avoid water wastage came into being
