Abstract

The utility model discloses an underground water perfusing device and relates to the field of underground water perfusion. The capacity of people for taking underground water is gradually enhanced, a water level of the underground water is lowered year by year, and the capacity of soil for resisting drought is lowered day by day. The underground water perfusing device aims to promote the fact that rain water is effectively perfused underground. According to the technical scheme, openings are formed in the two ends of a perfusion tube, the upper end of the perfusion tube is connected with a water container, the water container is located on the roof of a high-level building, the perfusion tube opening in the lower end of the perfusion tube is located underground, a water taking device is composed of a water taking tube, a piston and a water carrying tube, a check valve is arranged between the water taking tube and the piston, water is only allowed to pass through the water taking tube from a water pool to flow into the piton, a check valve is arranged between the piston and the water carrying tube, only the water in the piton is allowed to enter the water carrying tube, and the water in the water carrying water passes through a connecting tube and flows into the water container. The underground water perfusing device has the advantages that the perfusion tube is arranged from the roof to underground, if a water tube is filled with water, the openings of the perfusion tube reach several to scores of barometric pressure, and strong pressure can effectively promote water to enter a soil layer to form underground water.

Description

A kind of groundwater recharge device

Technical field

The present invention relates to the groundwater recharge field, particularly rise to higher height by foot-operated water with the pond, ground, the high hydraulic pressure that utilizes high water column to produce is extremely underground with hydraulic pressure.

Background technology

Because the development of technology, people take phreatic ability to strengthen gradually, and phreatic water level reduces year by year, causes the water content of soil shallow-layer more and more lower, and the ability that soil is resisted arid is day by day low.

Phreaticly recharge but few people and pay attention to, the phreatic certainly relatively difficulty of recharging also, main cause is: time of penetration is short, and osmotic pressure is little.In China, the precipitation rareness, precipitation time is short and concentrated, and most of precipitation becomes surface flow and flows to sewer or river, has only a spot of moisture can be penetrated into the shallow-layer of soil; And under the osmotic pressure of rainwater, the slit between the soil molecule is little, and the speed of infiltration is very slow, usually can see, and a heavy rain after the arid, behind the heavy rain, pick is opened soil at a glance, and it is moistening also having only simple upper soll layer.

Summary of the invention

Effectively perfusion is underground in order to promote rainwater, and the present invention designs a kind of groundwater recharge device.

The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of groundwater recharge device is characterized in that: the groundwater recharge device is made up of pond, water fetching device and device for casting; Device for casting is made up of intrusion pipe and water receptacle, the intrusion pipe both ends open, and the upper end connects water receptacle, and water receptacle is in the roof of highrise building, and the intrusion pipe opening of intrusion pipe lower end is positioned at underground, preferably descends 10-50 rice; Water fetching device is made up of intake pipe, piston, water lift pipe, between intake pipe and the piston flap valve is arranged, only allow water to flow to the piston from the pond through intake pipe, between piston and the water lift pipe flap valve is arranged, only allow the water in the piston to enter the water lift pipe, the water of water lift pipe flows in the water receptacle through tube connector.

There is a foot rest upper end of piston, the diameter of foot rest is at 30-40cm, and the piston inner core is the contact piston urceolus closely, and the diameter of piston inner core is 2cm, the height of bucket is 20-30cm in the piston, and a spring is arranged between the bottom of piston inner core top and piston urceolus.

Wherein intrusion pipe and water lift pipe are attached to the wall of high building, and in wall mounted; The pond is a pond of collecting rainwater, can be positioned at the underground of a square; Foot rest can have a plurality of, perhaps forms a circle, and there is a lot of exercise crowds on the square, and to the trampling of foot rest, the water with the pond when taking exercises rises on the high building by the crowd.

The invention has the beneficial effects as follows: the house in city is than higher, can reach tens to hundreds of rice, arrange that an intrusion pipe is from the roof to the underground, if fill water in the intrusion pipe, the pressure that water column in the intrusion pipe produces can reach several to dozens of atmospheric pressure, and water flows at the intrusion pipe opening of underground, powerful pressure can promote water to enter soil layer effectively, forms underground water; Utilize exercise crowd's exercise that water is risen to eminence, the usefulness of exercise is greatly improved; Behind the perfusion underground water, increase the humidity of soil, improved the drought-resistant ability of soil.

The specific embodiment

A kind of groundwater recharge device is made up of pond, water fetching device and device for casting.

Device for casting is made up of intrusion pipe 2 and water receptacle 3, intrusion pipe 2 both ends opens, and the upper end connects water receptacle 3, lower end intrusion pipe opening 1 is positioned at underground, preferably descend 10-50 rice, water receptacle 3 is in the roof of highrise building, and the height of present urban architecture is all at tens meters to more than 100 meters.Intrusion pipe 2 depends on the exterior wall of highrise building and fixes.

Water fetching device is made up of intake pipe 9, piston, water lift pipe 5, between intake pipe 9 and the piston flap valve is arranged, 10 process intake pipes 9 flow to the piston from the pond only to allow water, between piston and the water lift pipe 5 flap valve is arranged, only allow the water in the piston to enter water lift pipe 5, the water of water lift pipe 5 flows in the water receptacle 3 through tube connector 4.

The size of piston is relevant with the height of water lift, height such as floor is 100 meters, about 10 atmospheric pressure, if the people stands on the foot rest 6 of piston upper end, general adult body weight is more than 50 kilograms, an atmospheric pressure, be roughly one square centimeter of one kilogram of strength, thus the effective area of piston roughly at 5 square centimeters, this area is too little, a people is not enough to stand, so there is a foot rest 6 upper end of piston, the diameter of foot rest is at 30-40cm, and the piston inner core is contact piston urceolus 7 closely, the diameter of piston inner core is 2cm, and the height of bucket is 20-30cm in the piston.A spring 8 is arranged between the bottom of piston inner core top and piston urceolus 7, the effect of spring 8 is after the people leaves foot rest 6, promote to move on the foot rest 6 by elastic force, space between the moving piston inner core of last shipper pole and the piston urceolus 7 forms negative pressure, promotes the water in the pond 10 under the ground 11 to enter piston through intake pipe 9.

The similar foot-operated pump-up device of water fetching device, be the transmission of foot-operated pump-up device be gas, what this device transmitted is water, intensity and sealing requirements are much higher in addition, foot-operated pump-up device air pressure roughly is under 2 atmospheric pressure, the pressure reduction of this device reaches about 10, so the requirement of strength of flap valve, sealing, piston inner core, piston urceolus is higher.
