Description

Hydraulic drive-based self-swinging fire monitor Technical Field The invention relates to the technical field of fire monitor, in particular to a hydraulic drive-based self-swinging fire monitor. Background The fire monitor is used as a key fire-fighting equipment, the working principle is that water with specific pressure and flow is converted into kinetic energy through energy conversion, high-speed jet flow is formed to be ejected from a monitor head nozzle so as to realize remote fire suppression, the traditional fixed fire monitor is fixed in jet flow range, the fire-extinguishing direction is usually required to be manually held or adjusted through remote control in the operation process, however, the fire monitor is easy to have jet dead angles and has slower response speed under the dangerous or difficult real-time intervention scenes such as unmanned pump stations, ship lock pedestrian channels, petrochemical tank areas and the like, and the requirement of full-automatic fire extinguishing is difficult to meet. In view of the above-mentioned shortcomings, a fire monitor capable of automatically swinging appears in the prior art, wherein a typical scheme is an external driving type self-swinging monitor, the swinging action of the fire monitor depends on an independent electric motor or a pneumatic system, however, in extreme cases that power interruption or damage of a pneumatic pipeline due to high temperature is often accompanied in a fire scene, a power source of the device is easy to lose efficacy, so that a swinging mechanism is blocked, and the capability of large-scale covering and extinguishing is lost. In order to overcome the defect of relying on external power, the hydraulic self-swinging fire water monitor has been developed in the industry in recent years, and the key innovation is that the hydraulic self-swinging fire water monitor uses the hydraulic power of fire extinguishing agent as a driving source, the water is introduced into a water tank or an impeller cavity arranged on a fixed pipe to drive the impeller to rotate, and then a gun head executing mechanism is driven to realize automatic reciprocating swinging after the moment is increased by reducing the speed by a speed reducing mechanism, although the design gets rid of the dependence on an external power supply or an air source, the swinging mechanism is usually controlled by a fixed mechanical stroke (such as a cam or a crank structure), so that the reciprocating swinging angle of the gun head is solidified, and the structural characteristic exposes a new problem in practical application: firstly, the swing range cannot be adjusted according to the actual area of a fire scene, if large-angle sweeping is performed under the condition of small-area fire, a large amount of fire extinguishing water is ineffective to spray and resources are wasted, otherwise, if the area of the fire scene is large, a fire extinguishing blind area is generated due to the fixed swing angle; secondly, because the water flow continuously exists in the fire extinguishing process, the hydraulic driving mechanism also continuously runs, the gun head continuously swings, direct current coverage or small-amplitude sweeping is required when the fire extinguishing is carried out in a roadway, a long and narrow space or aiming at a specific point fire source, and continuous idle swing is not only beneficial to fire extinguishing, but also aggravates the waste of water resources and reduces the fire extinguishing efficiency. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a hydraulic-drive-based self-swinging fire monitor, which aims to solve the problems that the swing angle of the existing hydraulic self-swinging fire monitor is fixed, the adjustment according to the area of a fire scene is inconvenient, the continuous swing causes water resource waste and the like.
