Abstract

The utility model relates to a spraying temperature-decreasing device which has a chain-transmitting dynamic vertical-sweeping running-style and is used for a fireproofing rolling shade. The utility model comprises a packing-box, water-hoses, a ball-valve, a filter and sprayers. The utility model is characterized in that the utility model also comprises a motor, a direction-shifting link rod, a stroke-switch, a small chain-wheel, a chain, a big chain-wheel, a solenoid valve and a water-supply hose; the water hose connected with the ball valve, the filter and the solenoid valve in a serial order is arranged on the packing-box; the water-hose on which a plurality of sprayers are equally arranged in the shade-width scope is arranged under the packing-box through a supporting seat; the sprayer corresponds to the shade-face and the upper water-hose is communicated with the lower water-hose through a water-supply hose; the small chain-wheel is fixed on the transmission shaft of the motor; the water hose is fixed in the center of the big chain-wheel; the direction-shifting link rod is fixed at the other end of the transmission shaft of the motor; two stroke switches on two sides of the direction-shifting link rod are arranged on the soleplate of the packing box. With the spraying temperature-decreasing device, the fire-fighting water used for the temperature-decreasing of fireproofing rolling shade of the construction-establishment can be decreased by 97% with a better temperature-decreasing effect; and simultaneously the cost used for constructing and purchasing the fire-fighting establishments can be largely reduced.

Description

Fire resisting shutter is dynamically indulged with chain drive and is swept the spraying cooling device

One, technical field

The utility model belongs to the fire plant to surperficial coating liquid, particularly uses porous member liquid to be coated the fire plant of surface of the work.

Two, background technology

At present, fire-fighting when carrying out curtain face cooling operation, all adopts stationary nozzle or jet pipe to implement spray cooling with fire resisting shutter.What this shower nozzle or jet pipe can only be fixed sprays water to a certain subrange of curtain face, the curtain face other widerly can only make water flow automatically to the scope of operation by gravity, surface tension and factors such as out-of-flatness of curtain face and curtain face suction infiltration difference because of water, make roller shutter surface water yield skewness, desire to make the roller shutter surface can both get water for cooling and just must strengthen water consumption, at present, with discharge generally at 3L/m2.min, if like this, a large amount of fire demand waters are run off in vain.

Three, summary of the invention

At the above-mentioned defective that prior art exists, propose a kind of fire resisting shutter of meter and sweep the spraying cooling device with chain drive is dynamically vertical, make it roller shutter surface spraying good cooling effect, and all reduce the spray water consumption significantly, can also save the fire-fighting construction investment.

Technical solution adopted in the utility model is as follows.

A kind of fire resisting shutter is swept the spraying cooling device with chain drive is dynamically vertical, includes lodge, water pipe, ball valve, filter and shower nozzle, it is characterized in that:

1) it also has motor, commutation connecting rod, travel switch, minor sprocket, chain, hinge wheel, magnetic valve and water supply hose;

2) water pipe that is serially connected with ball valve, filter and magnetic valve successively is arranged on above the lodge, and the water pipe of uniform a plurality of shower nozzles is arranged on below the lodge by supporting seat in curtain face width degree, and shower nozzle is corresponding with the curtain face, and upper and lower water pipe is communicated with water supply hose;

3) minor sprocket is fixed on the drive axle of motor, the water pipe of uniform a plurality of shower nozzles is fixed on the hinge wheel center, put chain on hinge wheel and the minor sprocket, the commutation connecting rod is fixed on the drive axle of motor other end, and the lodge base plate is provided with 2 travel switches that are positioned at commutation connecting rod both sides;

4) be provided with the temperature sensor of curtain face and temperature controller and be communicated with magnetic valve, realize automatic adjusting curtain face spray water consumption.

Use the dynamically vertical spraying cooling device of sweeping of the utility model structure, can make the fire demand water that is used for the fire resisting shutter cooling in the Architectural Equipment reduce 97%, and good cooling effect, the construction and the funds of purchasing that can be used in fire-fighting cistern, fire extinguisher canvas hose and fire pump etc. simultaneously significantly reduce; Place promotion and implementation such as it is well suited in the market, storehouse and factory.

Five, the specific embodiment

Further specify the utility model fire resisting shutter below in conjunction with accompanying drawing and dynamically indulge the concrete structure of sweeping the spraying cooling device with chain drive.

A kind of fire resisting shutter is swept the spraying cooling device with chain drive is dynamically vertical, includes lodge 1, water pipe 7, ball valve 13, filter 14 and shower nozzle 8, it is characterized in that:

1) it also has motor 3, commutation connecting rod 9, travel switch 10, minor sprocket 11, chain 12, hinge wheel 13, magnetic valve 16 and water supply hose 6;

2) water pipe 7 that is serially connected with ball valve 14, filter 15 and magnetic valve 16 is successively put on lodge 1, the water pipe 7 of uniform a plurality of shower nozzles 8 is arranged on below the lodge 1 by supporting seat 5 in curtain face 18 width, shower nozzle 8 is corresponding with curtain face 18, and upper and lower water pipe 7 usefulness water supply hoses 6 are communicated with;
