Description

technical field [0001] The invention belongs to the technical field of municipal fire-fighting irrigation, in particular to a multifunctional municipal fire-fighting irrigation and cleaning device and a using method thereof. Background technique [0002] Compared with other sparsely populated places, due to the density of people, the concentration of property and the relative traffic congestion in cities, in the event of a fire or other dangerous situation, the firefighting time is urgent and the firefighting pressure is greater. Special fire-fighting pipelines are buried and regularly repaired, but the water supply capacity of fire-fighting pipelines has an upper limit; the same as the independently laid fire-fighting pipelines, municipal greening irrigation pipelines are also one of the commonly used municipal pre-buried pipelines, and the frequency of use is high, and the maintenance is more timely. If fire hydrants are used to extinguish fires and irrigation pipes are us...

Problems solved by technology

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a multifunctional municipal fire-fighting irrigation and cleaning device and its use method, aiming at increasing the fire-fighting water volume by converting the municipal irrigation device into a standby fire hydrant. supply, to solve the problems of urgent time for urban fire rescue and difficult water supply; similar to independently laid fire pipelines, municipal green irrigation pipelines are also one of the commonly used municipal pre-buried pipelines. Using irrigation pipes to replenish water sources while extinguishing fires with hydrants will further speed up fire extinguishing, reduce property losses and casualties. Similarly, using only water trucks to clean roads after rain or municipal maintenance also faces the same problem, but Different from fire-fighting pipelines, the water pressure of green irrigation pipelines is generally not high, which cannot meet the water pressure requirements for fire-fighting or municipal road cleaning. If a booster pump is installed on each irrigation device, the construction cost will be greatly increased. In order to To pressurize the irrigation device without greatly affecting the cost, this invention creatively proposes a residual pressure recovery type secondary pressurization system, using the principle of turning harm into benefit (using harmful factors to obtain beneficial effects), which will not be conducive to The residual water pressure of the downstream pipeline of the pressurized irrigation device is converted into the driving force of the pressurized device, and the cycle expansion and contraction of the miniature water-driven piston cylinder is realized through the electronic water flow reversing device. Extrusion irrigation device, but when the general piston resets, it will reversely compress the water flow, hinder the water flow to the outside world, and become the resistance in the pressurization process. In order to solve this problem, the invention creatively uses the principle of flexible shell and film ( Use a flexible shell or film instead of a three-dimensional structure), through a set of airbags and sliding rings at both ends of the airbag, the elastic-filled airbag booster piston can only pressurize in one direction during reciprocating motion, which solves the need for an external booster pump to The problem of realizing the active and one-way pressurization effect; different from manual spraying, the irrigation device of the present invention is a fixed structure, and the constant pressure spraying can only spray a specific area, while the general active angle adjustment device has a complex structure, The cost is high. In order to solve the problem of adjusting the spraying distance through a simple structure, the present invention creatively proposes a continuous flow rate control device. According to the principle stated in the fluid continuity equation, the liquid flow rate is changed by changing the throttle area to solve The problem of fixed spraying area of ​​fixed sprinkler irrigation device is solved, and the problem of uneven water flow in the spraying area is effectively solved by fan-shaped oblique sandblasting control device; in order to further simplify the structure and reduce the impact on cost, the present invention is based on the principle of versatility ( Make a part of an object or an object have multiple functions and eliminate the need for other parts) A multi-functional control joint is proposed, which can be used not only for spraying irrigation flow paths, but also for fire cleaning; with a multi-link protective cover The opening and closing device effectively solves the problem that the current low-pressure municipal irrigation pipeline cannot be quickly and effectively converted into a backup auxiliary facility for fire protection in the event of a fire hazard
