Description

Water is with clean water device and equipped with supply-water pump of the water with clean water device

Technical field

The utility model belongs to fire-fighting equipment technical field, and in particular to a kind of water band clean water device, and further relate to match somebody with somebody Have supply-water pump of the water with clean water device.

Background technology

Above mentioned water band refers mainly to fire hose, but is not definitely limited to fire hose, such as is included in using shape It is able to deploy under state and is able to the tool to form coil shape or be stacked in the form of a plurality of S-shaped circulations repeatedly in the stand-by state There are all kinds of water-feeding ＆ drainaging pipelines of compliance.Above mentioned clean water device can also claim de-watering apparatus, and its function is before residuing in The water stated in fire hose or water-feeding ＆ drainaging pipeline removes.

By taking the foregoing fire hose that fire department is commonly used as an example, after fire extinguishing disaster relief task terminates, fire hose need to be received Pick up to wagon, wagon such as Chinese patent CN202802600U（Hose laying fire fighting truck）、 CN101607118B（The fire-fighting equipment of fire-hose laying and pick device is installed）、CN10378512B（Water band is collected and spread If fire fighting truck）、CN103785126B（The fire fighting truck with function with automatic deploying and retracting）And CN103751931B（Fire hose is automatic Lay fire fighting truck）, etc..

As is known in the industry, after the fire extinguishing disaster relief terminates, substantial amounts of water is often remained in fire hose, is disappeared in foregoing water band Due to can not possibly effectively displace the water residued in water band when anti-car is tidied up, thus following technical problem be present：First, in the winter Season, then if can not be by fire-fighting because the relatively low such as the northern area of China of environment temperature reaches subzero one, 20 degree or even lower Residual water in water band is displaced, then freezeout certainly occurs, is just difficult in responding next time or even at all can not Fire hose under frozen state is sprawled, so as to influence the disaster relief；Second, due to frequently freezing and thawing, thus easily Influence the service life of fire hose；Third, after the fire hose for having water is tidied up in hose cart, loading capacity is caused to increase Add, be unfavorable for saving energy consumption of vehicles.

Current solution is：It will generally be residued in as far as possible in fire hose with manual work mode by fire fighter Water first give and displacing or being tidied up when displacing in wagon, on the one hand this mode increases fire fighter's to inaction Workload and operation intensity, another aspect expelling water effect are unable to reach expection.

For above-mentioned prior art, the applicant has made lasting and beneficial exploration and design, below will form finally The technical scheme to be introduced and in the case where taking secrecy provision through computer simulate deduce experiment be proved to be practicable.
