Description

Technical Field

[0001] The invention relates to the field of water storage, and in particular to a water storage system with both water flow metering and fire water supply functions. Background Art

[0002] In order to meet the detection range requirements of large-caliber water flow meters, the calibration equipment usually requires the water tank to have a sufficiently large water flow rate, a basically constant flow rate, and the circulating water quality can be monitored to avoid affecting the water meter or flow meter. Generally, a large-flow cold water device needs to be equipped with a water tank of about 100 cubic meters to ensure the circulating water flow of the calibration equipment and water storage and reuse, and the water tank is mostly made of fiberglass.

[0003] Fire water tanks are usually required in buildings or key fire protection areas. Fire water tanks are mainly used to provide fire water volume and water pressure at the initial start-up of the fire protection system, timely control of initial fires, and buy time for external firefighting. Therefore, it is a feasible solution to combine large-flow cold water devices with fire water tanks within a certain range, so that the requirements for fire protection can be met while meeting the technical requirements of metrological standards, avoiding duplication of construction and saving investment. However, the water tank volume of ordinary metrological verification devices is small, which cannot meet the requirements of fire protection, and cannot monitor the water volume, water quality, water temperature and water pressure in the water tank in real time. It also cannot meet the requirements of fire protection linkage and cannot solve the problem of automatic water cutoff of equipment when fire protection water is used. In addition, general fire water tanks have special fire protection requirements for water inlet pipes, water outlet pipes, liquid level gauges and sewage outlets, while large-flow cold water device water tanks pay more attention to the use conditions such as water quality and water flow.

[0004] Therefore, there is an urgent need to design a large-flow cold water device that can meet both fire-fighting and inspection functions. Summary of the invention

[0005] The purpose of the present invention is to provide a water storage system that can simultaneously meet the metering verification and fire water supply functions.

[0007] Wherein, at least one interface is arranged on the first side of the large-capacity water tank near the bottom, and the at least one interface is connected to the water pump group.

[0008] Wherein, the accommodating space is more than 200 cubic meters.

[0009] Wherein, at least two groups of interfaces are arranged on the second side of the water tank near the bottom, and the at least two groups of interfaces are respectively connected to the fire pump groups.

[0010] Wherein, a monitoring control panel is arranged on the second side of the large-capacity water tank.

[0011] Wherein, the monitoring control panel is provided with a water tank water level monitoring module.

[0012] The water storage system of the present invention solves the problem that ordinary calibration water tanks have small capacity and cannot meet the water needs of fire fighting. It can monitor the water quantity, water quality, water temperature and water pressure in the water tank in real time, realize fire fighting linkage and alarm, and avoid duplicate construction of fire fighting water tanks.
