Problems solved by technology
[0002] As a fire emergency equipment, outdoor fire hydrants play a vital role in daily fire rescue. At the same time, some sprinklers also take water from fire hydrants. However, the existing fire hydrants generally have simple structures, and the water filling time of sprinklers is longer. Taking a 5-ton sprinkler as an example, it takes 10 minutes or more to fill up, and the operator often fails to close the valve in time due to negligence, resulting in waste of water resources

The invention relates to the field of firefighting equipment, in particular to an automatic cut-off firefighting device which at least comprises a fire hydrant body. The automatic cut-off firefighting device is characterized in that an electronic flow meter and an electric valve are fixed to a water outlet of the fire hydrant body, a setting unit is arranged on the top of the fire hydrant body, and the electronic flow meter, the electric valve and the setting unit are electrically connected with a control unit. The automatic cut-off firefighting device has the advantages that the electric valve can be opened and closed under the automatic control of the control unit, and accordingly wastage of water resources due to the fact that the valve is not timely closed after water feeding is completed can be effectively prevented.
Description
technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to an automatic shut-off fire-fighting device. Background technique [0002] As a fire emergency equipment, outdoor fire hydrants play a vital role in daily fire rescue. At the same time, some sprinklers also take water from fire hydrants. However, the existing fire hydrants generally have simple structures, and the water filling time of sprinklers is longer. Taking a 5-ton sprinkler as an example, it takes 10 minutes or more to fill up, and the operator often fails to close the valve in time due to negligence, resulting in waste of water resources. Contents of the invention [0003] The object of the present invention is to provide an automatic shut-off fire-fighting device, the fire hydrant can set the water addition amount, and automatically stop adding water after reaching the specified water addition amount, so as to avoid the waste of water resources. [0004] The tec...
