Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment monitoring, in particular to a fire-fighting device for fire-fighting facilities. Background Art

[0002] Fire water systems such as indoor fire hydrant systems and automatic sprinkler systems are generally composed of fire pumps, fire water tanks, pipe networks, valves, sprinkler heads or fire hydrant boxes. After the construction is completed, the fire water system needs to be regularly maintained and inspected, and the competent industry department should supervise it to ensure that it is intact and effective. At present, the status of the valves in the fire water system pipe network basically relies on manual on-site inspection.

[0003] The fire water system has a huge pipe network and many valves. The maintenance and inspection of the fire water system mainly rely on the maintenance unit to manually check the status of water pumps and valves on the spot, which requires high technical ability and sense of responsibility of the personnel. However, since fire-fighting facilities do not generate economic benefits, various industries in society invest less in them, and the remuneration of technical personnel is difficult to guarantee. In addition, manual inspection of a large number of valves is time-consuming and laborious, and it is inevitable that there will be omissions, so it often fails to achieve the expected results and cannot ensure that the system is intact and effective. Due to limited inspection time, it is impossible for the competent departments of the industry to conduct a comprehensive on-site inspection. Effective supervision cannot be formed by spot checks alone. At present, formal supervision can only be completed by checking fire protection systems, maintenance and inspection data. On the surface, they have fulfilled their duties, but in fact, due to the lack of reliable technical means, effective supervision has not been achieved. If a fire accident occurs, it is difficult to exempt the supervision responsibility because the fire-fighting facilities have not played their due role. According to relevant regulations, the fire control room must implement a 24-hour duty system, with no less than 2 people on each shift and the duty personnel must hold a professional qualification certificate for fire control room operation. The duty personnel must ensure that the valves of the fire water system are always open to ensure that the fire water system can function in the event of a fire. In fact, this work requires high technical capabilities of the fire control room duty personnel, which is generally difficult to implement at present. The number of duty personnel is a heavy burden for enterprises.
