[0002] A fire water tank is a man-made water storage facility for fixed or mobile fire water pumps to absorb water. A drinking water tank is a water tank used to store drinking water. According to the relevant regulations of the "Design Standard for Building Water Supply and Drainage" (GB50015-2019), the water storage renewal time in the drinking water tank should not exceed 48 hours; when the water in the fire water tank is often reduced due to pipeline leakage, tank leakage, evaporation, etc., the signal is often transferred through a level meter to control the start and stop of the water supply pump or the drinking water tank and the fire water tank are built together to replenish water. The former requires an additional set of water supply pumps for the fire water tank, which makes the pump room occupy a large area and the civil engineering investment high; the latter requires frequent renewal of the water storage in the tank, which increases energy consumption.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figures 1 to 3 The utility model includes a fire water pool 10 and a domestic drinking water tank 8. The domestic drinking water tank 8 is equipped with a water replenishment pump and a water replenishment pipe 5 for replenishing water therefor (generally, a liquid level sensor provided on the domestic drinking water tank 8 can be used to control the replenishment pump in linkage, and the implementation is implemented with reference to the prior art). The bottom of the domestic drinking water tank 8 is connected with a domestic water supply pipe 7 (used to supply domestic drinking water to the downstream terminal, and the implementation is implemented with reference to the prior art). The domestic drinking water tank 8 is arranged above the top of the fire water pool 10 (as long as it is ensured that the height difference between the two can be utilized to realize that the domestic drinking water tank 8 can directly replenish the fire water pool 10). The bottom of the domestic drinking water tank 8 is connected with a water outlet pipe 4, and the end of the water outlet pipe 4 is a water outlet pipe drainage section. The axis of the water outlet pipe drainage section is vertically arranged and the pipe mouth of the water outlet pipe drainage section faces downward. The position of the pipe mouth of the water outlet pipe drainage section is lower than the position of the connection point between the water outlet pipe 4 and the domestic drinking water tank 8. The water outlet pipe drainage section is connected with a coaxial corrugated telescopic hose 6, and the lower end of the corrugated telescopic hose 6 is connected with a U-shaped connecting pipe 2 The U-shaped connecting pipe 2 includes a first vertical pipe and a second vertical pipe arranged in parallel, the lower end of the first vertical pipe and the lower end of the second vertical pipe are connected through an intermediate transition pipe, the first vertical pipe is coaxial with the corrugated telescopic hose 6, the upper end of the first vertical pipe is connected to the lower end of the corrugated telescopic hose 6, the U-shaped connecting pipe 2 is arranged in the fire water tank 10, the bottom of the U-shaped connecting pipe 2 is fixedly connected to the buoyancy member 3, and the fire water tank 10 is provided with a buoyancy plate guide mechanism that allows the buoyancy member 3 to rise and fall vertically along the water surface; the fire water tank 10 A limit bracket is fixedly provided on the top of the pool 10, and a limit plug 9 is fixedly installed on the limit bracket just above the second vertical pipe. The position of the limit plug 9 is not higher than the position of the connection point between the outlet pipe 4 and the drinking water tank 8 (the limit position design enables the U-shaped connecting pipe 2 to use the siphon principle to replenish water to the fire water pool 10 in the entire vertical lifting range). The limit plug 9 has a first state of closing the upper end of the second vertical pipe and a second state of being separated from the upper end of the second vertical pipe. In specific implementation, when the liquid level of the fire water pool 10 is high, the buoyancy member 3 compresses the corrugated telescopic hose 6 by buoyancy, and at the same time lifts the U-shaped connecting pipe 2 to the limit plug 9, so that the water outflow of the drinking water tank 8 stops; when the liquid level of the fire water pool 10 is low, the U-shaped connecting pipe 2 stretches the corrugated telescopic hose 6 under the action of gravity, and at the same time descends, and the U-shaped connecting pipe 2 is separated from the limit plug 9, so that the drinking water tank 8 starts to flow out.

[0015] The position limiting plug 9 can be implemented in a variety of ways. For example, a "flat plate with a sealing gasket at the bottom" can be used to directly seal the end face of the upper end of the second vertical tube. A sealing member with a conical surface structure or a spherical surface structure can also be used to directly seal the inner cavity of the upper end of the second vertical tube (the sealing member can be made of a material with a certain elasticity, or only a sealing ring or a sealing gasket layer can be added to the outer surface to improve the sealing performance). Sealing members with a spherical surface structure can be collectively referred to as "spherical members". In order to make the structure simple and reliable, the position limiting plug 9 in the utility model is preferably a spherical member, and the upper end of the second vertical tube is a conical tube with an upper inner diameter larger than the lower inner diameter.

The buoyancy member 3 only needs to have the ability to always float on the water surface under the working environment of the utility model, and can be made of a light material into a plate shape, or can also adopt a hollow buoyancy tube and other structural forms.
