Description

Water supplementing device for fire-fighting pool Technical Field The utility model relates to the technical field of fire protection systems, in particular to a water supplementing device for a fire-fighting pool. Background In order to accelerate the improvement work of old communities, the living environment is continuously improved, the requirements of people on good life are met, and in the improvement of old communities, the improvement of a fire protection system is particularly important. Many existing fire facilities do not meet the current requirements due to modification of the specifications, wherein the modification of the volume of the fire-fighting pool water is difficult. In old district transformation, fire-fighting pool dilatation faces structural limitations and site condition constraints. In the prior art, if the water quantity can not be reduced through the municipal fire hydrant, innovative measures are needed to be adopted to supplement the fire water. The traditional capacity expansion scheme has high cost and difficult construction. Therefore, an automatically controlled water replenishment device is needed. Disclosure of utility model The utility model aims to solve the technical problems, and aims to provide a water supplementing device for a fire-fighting pool, which solves the problem of insufficient water quantity of the fire-fighting pool in the old improvement project and compensates the water quantity of the fire-fighting pool. In order to achieve the aim, the utility model provides a fire-fighting water tank water supplementing device, which comprises a raw fire-fighting water tank, a control box, a supplementing water tank, a supplementing water pipeline, a liquid level sensor and a first valve, wherein the supplementing water tank is arranged near the raw fire-fighting water tank, the supplementing water pipeline is arranged between the supplementing water tank and the raw fire-fighting water tank, the liquid level sensor is arranged in the raw fire-fighting water tank, and the first valve is arranged on the supplementing water pipeline; The liquid level sensor is used for monitoring the water level in the original fire water tank and generating a signal; The control box is used for receiving the signal of the liquid level sensor, and opening the first valve when the water level of the original fire-fighting water tank is reduced to a preset water level, and supplementing the water of the supplementing water tank into the original fire-fighting water tank. Preferably, the liquid level of the replenishing water tank is higher than the liquid level of the original fire water tank. Preferably, the volume of the replenishing water tank is determined according to the water shortage of the original fire water tank. Preferably, the pipe diameter of the water supplementing line is determined based on the design flow rate of the fire pump. Preferably, a second valve is arranged on the water replenishing pipeline between the water replenishing tank and the original fire water tank and is used for manually starting emergency water replenishing when the first valve fails. Preferably, the first valve is an electric valve; the first valve is electrically connected with the control box. Preferably, the liquid level sensor is one of a floating ball sensor, a pressure sensor or an ultrasonic sensor. Preferably, a check valve is arranged at the joint of the water supplementing pipeline and the original fire water pool, and the check valve is used for preventing water in the water supplementing pipeline from flowing backwards. Preferably, the water supplementing pipeline is a stainless steel pipeline or a polyvinyl chloride pipeline. Preferably, an antirust coating is arranged on the surface of the box body of the control box, and a sealing rubber strip is arranged on the inner side of the box door of the control box. According to the description and practice, the water replenishing device for the fire-fighting water tank is communicated with the existing fire-fighting water tank through the water replenishing pipeline, wherein the water replenishing tank is higher than the highest running liquid level of the fire-fighting water tank to form a height difference, the liquid level sensor is arranged inside the fire-fighting water tank and is used for continuously monitoring the change of the water storage liquid level and transmitting a dynamic water level signal to the control box, and the control box automatically starts water replenishing of the water replenishing tank when the fire-fighting water causes the liquid level of the fire-fighting water tank to drop to a critical threshold value, and terminates water replenishing operation after the liquid level is restored to a safe interval. The device does not need to reform the raw water pool structure, and can accurately control the water quantity, avoid overflow.
