Automatic tracking and positioning jet fire extinguishing device

Abstract

The invention discloses an automatic tracking and positioning jet fire extinguishing device, which comprises a jet pipeline with a jet port and horizontal and vertical rotating devices driven by a power source, a fire detection alarm device controlled to work by an onboard controller, a horizontal scanning and positioning detection device and a vertical scanning and positioning detection device which are arranged on the jet pipeline. The jet pipeline is an S-shaped water passage consisting of a water inlet bent pipe and a water outlet bent pipe; the horizontal rotating device is arranged at the inlet of the water inlet bent pipe, and the vertical rotating device is arranged at the joint of the water inlet bent pipe and the water outlet bent pipe; the horizontal scanning and positioning detection device is fixed at the water outlet of the water inlet bent pipe through a support frame, and the vertical scanning and positioning detection device is fixed at the water outlet of the water outlet bent pipe through a support frame; a water flow rectifying device is arranged in the water outlet bent pipe; and a columnar mist jetting adjusting device and a camera are arranged on the jet port. The device is reasonable and compact in structure, and can be used for reliably detecting and accurately warning a fire in a large space.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to an automatic tracking and positioning jet fire extinguishing device. Background technique [0002] Most of the fire extinguishing devices (fire water monitors) used on the market are fully manual or electronically controlled, and there are also automatic fire extinguishing types. The manual type can only control the fire water cannon to extinguish the fire by shaking the hand wheel installed on the fire monitor. The electric control type can extinguish the fire by manipulating the control button on the control panel. Although the automatic fire extinguishing type fire monitor has the function of automatic fire extinguishing , but the fire detection during fire extinguishing is to rely on the smoke generated during the fire to block the infrared network composed of infrared transmitting equipment and receiving equipment, that is, the infrared receiving equipment cannot receive the in...

The manual type can only control the fire water cannon to extinguish the fire by shaking the hand wheel installed on the fire monitor. The electric control type can extinguish the fire by manipulating the control button on the control panel. Although the automatic fire extinguishing type fire monitor has the function of automatic fire extinguishing , but the fire detection during fire extinguishing is to rely on the smoke generated during the fire to block the infrared network composed of infrared transmitting equipment and receiving equipment, that is, the infrared receiving equipment cannot receive the infrared rays emitted by the transmitting equipment and send out a fire alarm. When the infrared rays are blocked, a "fire alarm" will be issued, and the false alarm rate is extremely high; and when the space is large, the infrared network is not dense enough or the smoke does not reach a certain concentration, false alarms or serious alarm delays may occur

At the same time, since the fire positioning relies on the intersection point (X, Y) coordinates of the smoke shielding infrared network and the 3D model established on the host computer to calculate the horizontal rotation angle and vertical rotation angle of the fire monitor, so that the spray hole is aimed at the fire position, due to the smoke There is drift, so the occluded coordinates are not necessarily the real fire coordinates. Coupled with the error calculated by the host computer and the execution error of the fire monitor, the actual spray position may be far from the fire position. If the fire burns violently, the smoke If the amount of generation is large, many or all coordinates may be covered at the same time, and the automatic positioning function will lose its effect
