Abstract

The utility model discloses a hydraulic reciprocating-type pressure-boosting water supply device for fire fighting of super high-rise buildings, hydraulic oil pumps are communicated with high-pressure oil pipes at one end of a reversal valve and one end of each double-piston-rod double-acting oil cylinder; two ends of each piston rod of the double- piston-rod double-acting oil cylinder are respectively connected with pistons of a pressure-boosting water transferring cylinder; the hydraulic oil pumps output high pressure oil to the reversal valve, and the high pressure oil is alternately injected into the two parallel double- piston-rod double-acting oil cylinders and a contactless travel switch for the alternant transmitting; the reversal valve alternately injects the high pressure oil into the two double- piston-rod double-acting oil cylinders; the pistons of the pressure-boosting water transferring cylinder, which act on the double- piston-rod double-acting oil cylinders and positioned at two ends, perform the reciprocating motion, and high pressure water passes through the pressure-boosting water transferring cylinder to shut off a one-way water inlet valve, therefore, high pressure water of a one-way water outlet valve is ejected to a water outlet for the output, and the double-piston-rod double-acting oil cylinders perform the reciprocating motion alternately so as to continuously suck and output the high pressure water to meet the requirement of the fire fighting of the super high-rise buildings with 200-600m in height.

Description

High-rise building fire-fighting hydraulic reciprocating type supercharging waterworks

Technical field

The utility model belongs to the fire-fighting equipment technical field, relates to a kind of waterworks, and a kind of high-rise building fire-fighting high-voltage high-speed waterworks especially are provided.

Background technology

Along with socio-economic development, the big city high-rise building is more and more in the world, the superb more fire of high-rise building of Lou Yuejian is rescued has been global problem.

At present, high-rise building was sued and laboured aerial ladder at described height from the outside, building when fire took place, the highest have only hundred meters, fire-fighting lance (water cannon) is described to highly maximum 100 meters, effective method utilizes in the building fire hydrant inside to sue and labour on higher height, existing fire demand water pumping unit is based on centrifugal pump mostly, conventional outlet pressure generally water flow between the 0.8-1.4Mpa at the 20-120C/s lift between 100-200m, its discharge pressure, flow, and lift all can't satisfy high-rise building fire-fighting needs, water flow when domestic existing high-power diesel power fire pump unit works alone at present, pressure, the water direct sending can't be reached the highest 600m height, high-rise building can't satisfy the demand of high-rise building fire demand water.

Summary of the invention

The utility model discloses a kind of high-rise building fire-fighting hydraulic reciprocating type supercharging waterworks, the high-rise building fire demand water can't go directly superelevation top layer water tank fast to satisfy the demand of fire demand water in the solution prior art, solving the inner feedwater of fire-fighting saves oneself, an anhydrous available difficult problem, the utility model comprises, power set, hydraulic oil pump, reversal valve, the double piston-rod double-act-ing hydraulic J-Horner, the water pressurized cylinder, the water pressurized cylinder piston, the suction check valve, press water goes out water one-way valve, high pressure poultry energy device, static position switch, hydraulic oil oil return pressure reducing radiator, the high-speed turbine water pump, the hydraulic fluid pressure pump, the water under high pressure Pressure gauge, high-pressure water pipeline, water tank, hydraulic oil container, the double piston-rod hydraulic jack is two cylinder parallel connections, according to fire demand water and highly difference also can two hydraulic jacks form independently that two bigger discharge capacities of device supply water.

Description of drawings

The utility model has 4 water inlets and links to each other with water tank, and each water inlet pipe is connected by water-supply-pipe with two water feeding one-way valves.

Hydraulic oil pump is connected with high-pressure rubber pipe with reversal valve, the reversal valve output oil pipe is connected with an end of double piston-rod double-act-ing hydraulic J-Horner respectively, the other end two cylinders of double piston-rod two-way cylinder are connected formation hydraulic circuit. The two ends piston rod of double piston-rod two-way cylinder links to each other with the water pressurized cylinder piston at two ends respectively, the reciprocating motion of hydraulic jack drives two ends water pressurized cylinder piston by piston rod, alternately suck by suction valve, water one-way valve is backed down out in the water release of the piston other end push pressure piping, constantly move back and forth the effect that reaches continuous suction and water outlet, make the glassware for drinking water of release that certain pressure be arranged.

The specific embodiment

Power set drive hydraulic oil pump, drive shaft turns produces hydraulic oil and is moved to the left the piston D1 water under high pressure that drive the water pressurized cylinder AC1 that be connected left hand piston rod end to reversal valve 4 from reversal valve to the piston of double piston-rod double cropping and oil cylinder A double-piston effect oil cylinder A through high-pressure oil pipe and closes check valve A2 and back down check valve A1 and enter pressure piping, water pressurized cylinder AC1 right side, the piston C2 that the right hand piston rod end of double piston-rod two-way cylinder drives water pressurized cylinder AC2 raises setting-out and backs down check valve A5 left water under high pressure is pushed pressure piping, water pressurized cylinder piston D2 closes A6, right side water inlet check valve is opened, water is inhaled in the piston right side cylinder of water pressurized cylinder AC2, two ends of double piston-rod two-way cylinder do not have static position switch 1SQ, 2SQ, alternately signal respectively and make 3-position 4-way electro-hydraulic reversing valve (4) commutation, high pressure poultry can device (6) be used to reduce the water pressurized cylinder because hydraulic jack commutation causing hydraulic shock hydraulic pressure flows stable high voltage hydraulic pressure, replacing reciprocal work done for AB2 double piston-rod double-act-ing hydraulic J-Horner drives two ends water pressurized cylinder piston and constantly replaces two-way inspiration and release High-Pressure Water and enter pressure piping and add scooter 6000C/ branch discharge capacity through the turbine high-speed water, pressure reaches as high as 10Mpa, maximum pump send height can reach 600 meters, delivers to 600 meters height in 10 minutes.

Claims

1. high-rise building fire-fighting hydraulic reciprocating type supercharging waterworks is characterized in that: 1. the every end water delivery of double piston-rod two-way cylinder two ends drive supercharging water delivery cylinder piston pressurized cylinder is all back and forth done; 2. every supercharging water delivery of merit cylinder two ends are all adorned a check valve and are controlled water inlet, water outlet, output water under high pressure automatically; 3. transfer to turbine speed-raising water pump through high-voltage tube and accelerate flow velocity, make high-voltage high-speed water, reach top layer fast and satisfy the fire-fighting needs along pipe special.
