An overflow detector 311 is arranged at the top of the water storage tank 31, when the liquid level in the water storage tank 31 reaches the position of the overflow detector 311, the electric valve 336 is closed, specifically, both the overflow detector 311 and the electric valve 336 are connected with the controller 4, when the overflow detector 311 detects that the water storage tank 31 overflows (the water level reaches the position of the overflow detector 311), a signal is transmitted to the controller 4, and the electric valve 336 is controlled by the controller 4 to be closed so as to cut off the water inlet pipeline 33.
Wherein, concretely: the inlet line 33 includes a first circular line 331, an inlet branch line 332, and an outlet branch line 333.
One end of the water inlet branch pipeline 332 is connected with municipal tap water, and the other end is connected with the first annular pipeline 331; in this way, municipal tap water is pumped into the first annular pipeline 331 through the water inlet branch pipeline 332, and it should be noted that a plurality of water inlet branch pipelines 22 may be provided.
One end of the water outlet branch pipeline 333 is connected with the first annular pipeline 331, and the other end is connected with the water storage tank 31; the electric valve 336 is disposed on the water outlet branch pipe 333, and when the electric valve 336 is opened, the water in the first annular pipe 331 is pumped into the water storage tank 31 through the water outlet branch pipe 333.
One end of the water outlet branch pipe 333 connected with the water storage tank 31 is provided with a ball float valve 313, the ball float valve 313 is positioned in the water storage tank 31, and the installation height of the ball float valve 313 is lower than that of the overflow detector 311.
In this embodiment, the first stop valves 334 are disposed on both sides of the connection point between the first annular pipeline 331 and the water inlet branch pipeline 332, and both sides of the connection point between the first annular pipeline 331 and the water outlet branch pipeline 333, and the first stop valves 334 are disposed on the first annular pipeline 331; thus, when a failure occurs at a certain point (for example, a certain point is broken) on the first circular pipe 331, the first stop valves 334 on both sides of the failure point may be closed, so that the first circular pipe 331 can be normally supplied with water.
The water inlet branch pipe 332 is provided with a first one-way valve 335 to ensure one-way water passing through of the water inlet branch pipe 332.
The water inlet end of the water pump 32 is connected with the water storage tank 31, and the water outlet end is connected with a water supplementing pipeline 34; the water pump 32 is mainly used for pumping water in the water storage tank 31 and guiding the water to the water replenishing pipeline 34 from the water outlet end of the water pump; it should be noted that a plurality of water pumps 32 may be provided to connect with the water storage tank 31, and the specific number is not limited herein, wherein the water pumps 32 are connected with the controller 4.

A second stop valve 343 is arranged on both sides of the connection point of the second annular pipeline 341 and the water pump 32 and both sides of the connection point of the second annular pipeline 341 and the water supply branch pipeline 342; thus, when a certain point on the second annular pipeline 341 fails (for example, a certain point is broken), the second stop valves 343 on both sides of the failure point can be closed, so that the second annular pipeline 341 can also supply water normally. The outlet end of the water pump 32 and the water replenishing branch pipe 342 are provided with a second one-way valve 344.
In this embodiment, a pressure sensor 345 connected to the controller 4 is disposed at the water outlet end of the water pump 32, and the operating frequency of the water pump 32 is controlled by a pressure signal detected by the pressure sensor 345.
The implementation principle is as follows: under normal conditions, the pump room water supply system 2 supplies water for the cooling tower.
When the pump room water supply system 2 breaks down, the liquid level in the water pan of cooling tower descends gradually, the liquid level sensor 11 in the cooling tower transmits the detected liquid level signal to the controller 4, and when the liquid level is lower than the preset value, the controller 4 sends an instruction to start the water pump 32 in the emergency water supply system 3. At this time, the water pump 32 pumps the water in the water replenishing tank to the water replenishing pipeline 34, and then the water is guided into the cooling tower through the branch pipeline 22 and the water inlet pipe 12 of the cooling tower for the equipment to use.
In the process, the liquid level in the water storage tank 31 is lowered, at the moment, the electric valve 336 is in an open state, tap water is continuously pumped into the water storage tank 31 through the water inlet pipeline 33, and when the liquid level in the water storage tank 31 reaches the position of the overflow detector, the electric valve 336 is closed, and water inlet is stopped; thus, the dynamic circulation water replenishing ensures that a certain amount of water is always stored in the water storage tank 31. Therefore, when the municipal tap water is cut off, the water can be used by depending on the amount of water stored in the water storage tank 31, and the water can be supported to the arrival of the waterwheel by depending on the amount of water stored therein. When the water truck arrives, water can be replenished into the water tank 31 through the water replenishing port 312 of the water tank 31.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of the present invention.
