Description

Balanced fire hose rapidly-unfolding water outlet and collecting device

Technical Field

The invention relates to a balanced fire hose quick unfolding water outlet and collecting device.

Background

The fire hose is one of necessary equipment for firemen during fire fighting and rescue, the existing fire hose is basically 20m in standard length, and the main problem during use is that the winding mode during collection is different from that during use.

When a fireman is in fire fighting and rescue, the fireman firstly drives the fire engine to be close to a fire scene, one end of the fire engine is connected with a fire hydrant or a water supply vehicle and other water sources, the other end of the fire engine is connected with a main line water hose or a linear water hose, the main line water hose continuously extends into the fire scene after reaching a water separator position, the end parts of the fire engine and the water separator can be directly connected with fire-fighting lances, and two or more fire-fighting lances can also be connected through the water separator. And after the fire extinguishing is finished, the water belt is collected.

Because the two ends of the water hose are respectively provided with the connectors which are in a male-female circular ring shape, the male connector can be inserted into the female connector, and thus, the multiple sections of water hoses can be connected together. The connectors are all made of metal materials capable of bearing large pressure, the connector is large in mass and can keep a round shape without deformation under the conditions of filling water and not filling water, and the water belt is made of soft materials, is light in mass and is flat and banded under the condition of not filling water.

At present, the water hose is basically wound and wound by taking a middle point in a winding and winding mode, namely the water hose is folded and then wound by using a reel. The reel is pressed with the hosepipe connector in the winding, and the direct winding is in the inside of hosepipe, but because the hosepipe connector can not warp, and weight is big, consequently, the hosepipe after the winding is asymmetric shape, forms a quality unbalance point in the position of hosepipe connector. Because of the rapid action required during each battle, the firefighters cannot use the wounded hose by rapidly pulling the hose due to the quality imbalance, and only after the hose is thrown, the firefighters can use the hose. Therefore, the fire hose cannot be directly used in next fighting, and therefore the fire hose must be rearranged after the fire hose is returned, and the fire hose is placed in the equipment box. One arrangement method is to fold the fire hose once and then coil the fire hose, and arrange the hose connector outside the fire hose; the fire hose is required to be cleaned and dried, the fire hose is rolled up firstly, the two joints are slightly staggered when the fire hose is rolled up, then the fire hose is folded in half and is rolled up from the middle part, and finally when the fire hose is coiled, the two joints of the fire hose are just above.

In the other method, the water hose is folded back and forth according to the rated length of 0.5-1.0 meter, and the water hose can be pulled directly in the next battle because the influence of unbalanced quality of the water hose connector is avoided. But arrange in order again after accomodating, this greatly increased the fire fighter's work load, some fire hose length can reach 50m even, and when folding, the thickness of folding toward the return point is in than middle thickness, folding to last time, both sides are high, and the middle is low, and the hosepipe on both sides can even collapse toward the centre. This also causes the firefighter to be unsmooth when taking the water from the hose.

Detailed Description

In order to more clearly illustrate the present invention, embodiments of the present invention are further described below with reference to the accompanying drawings.

Example one

As shown in figures 1-3, the invention comprises a base and side walls, wherein the side walls are connected with the base into a whole, the side walls are arranged in parallel relatively, the upper part of the side walls is arc-shaped, and a handle is arranged at the upper part of the side walls and has the functions of water carrying a stop lever and side wall rigidity increasing. The middle part of the side wall is provided with a bearing, the inner hole of the bearing is provided with a rotating shaft, the middle part of the rotating shaft is provided with an elbow hole, an elbow is arranged in the elbow hole, and the elbow and the central pipe are mutually communicated pipelines. After the rotating shaft, the central pipe and the elbow are combined, the mass is approximately uniformly distributed along the axis direction of the central pipe, so that the central pipe, the elbow and the rotating shaft cannot generate eccentric force when rotating. The elbow is connected with the water hose connector, preferably after the rotating shaft, the central pipe, the elbow and the water hose connector are combined, the water hose connector is approximately uniformly distributed in mass along the axis direction of the central pipe, so that the central pipe, the elbow, the water hose connector and the rotating shaft can not generate eccentric force when rotating.

The central tube is provided with a switch, and the switch adopts a ball valve. The central pipe can be connected with the water separator again to satisfy a plurality of squirts work. The water separator is also provided with a switch.

The rotating shaft is provided with a rocker and a crank, and the rotating shaft can rotate through the crank.

The corner at the joint of the base and the side wall is also provided with a roller, when the base is placed still, the lowest part of the roller does not exceed the plane of the base, and when the base is placed obliquely, the roller can contact the ground.

The working conditions are as follows: when the water hose is collected, the rotating shaft is driven to rotate by rotating the crank, and the water hose is wound on the rotating shaft by the rotating shaft. When the water hose is used, the water hose connector at the water hose end wound on the rotating shaft is connected to a fire engine, then the handle is pulled, the fire fighting truck is pulled away by using the roller, the water hose is continuously unfolded in the pulling away process, and due to uniform mass distribution, eccentric force cannot be generated, so that a fireman can be connected with the water gun to fight fire when arriving at a fire scene.

Example two

On the basis of the first embodiment, the rocker and the crank are eliminated, a worm wheel and a worm are arranged for driving, the worm is driven by a motor hinged on the side wall, and the upper end of the worm is positioned by a worm positioning piece to ensure that the worm is matched with the worm wheel. The worm positioning piece is pressed by a fixed seat fixedly connected on the side wall through a spring. The fixing seat and the worm positioning piece are both provided with locking columns, and when the locking columns are close to each other, the locking columns can lock the ring for positioning so as to separate the worm from the worm wheel. The base is provided with a power supply which supplies power to the motor.
