Remote water pressure monitoring terminal of smart outdoor fire hydrant, and smart outdoor fire hydrant

Abstract

The invention discloses a remote water pressure monitoring terminal for a smart outdoor fire hydrant, and the fire hydrant. The monitoring terminal comprises a monitoring terminal body, a retaining wire casing and a water pressure detecting probe, which are sequentially connected, wherein a control unit is provided in the monitoring terminal body, the middle portion of the monitoring terminal bodyis provided with a through hole and the bottom is provided with a mounting seat for inserting into the opening mounted on the top end of the fire hydrant, the top of the water pressure detecting probe is provided with a mounting post for the through hole installed on the valve core of the fire hydrant, the water pressure detecting probe is provided with a pressure sensor unit, the cable of the pressure sensor unit passes through the inner hole of the mounting post and is electrically connected to the control unit via the sealed retaining wire casing; and the fire hydrant comprises the aforementioned monitoring terminal. The invention is convenient and quick to install, adopts low power consumption design, has long service life, can be adapted to normal operation of the system under ultra-low temperature, and has accurate and timely induction function of fire water pressure and water temperature change, and accurate real-time monitoring function of position of the fire hydrant, stealing, impacting, tilting and water taking / leakage status.

Description

technical field [0001] The invention relates to fire hydrant monitoring equipment, in particular to an intelligent outdoor fire hydrant remote water pressure monitoring terminal and an intelligent outdoor fire hydrant. Background technique [0002] The outdoor fire hydrant is a common fire-fighting equipment. It generally includes a fire hydrant shell with a valve core. A locking cover is installed at the top opening of the fire hydrant shell. A threaded hole is installed on the locking cover. A matched operating rod, the lower end of the operating rod is connected with the valve core through a connecting piece. Its working principle is: in the default state, the valve core and the valve body of the fire hydrant shell are closely matched to achieve sealing. A gap is formed, so that the water in the fire-fighting pipeline flows out from the gap, and flows out through the water outlet provided on the side of the fire hydrant shell. Therefore, the traditional outdoor fire hyd...

Problems solved by technology

However, this solution has the following problems in the application process: (1) The monitoring device is installed at the bottom connecting flange of the outdoor fire hydrant, but in fact the bottom connecting flange of the outdoor fire hydrant is generally buried under the soil or even concrete, so It is very difficult to install the monitoring device

(2) The monitoring device is installed at the bottom connecting flange of the outdoor fire hydrant. When the water pressure is detected by the sensor and sent to the remote server, the bottom connecting flange of the outdoor fire hydrant is generally buried under soil or even concrete, causing network Poor signal, difficult to achieve reliable and stable data transmission
