Flood-prevention leakage-stopping device

Technical field

The present invention relates to a kind of device that utilizes liquid leak stopping, the leak stopping of can easily controlling flood on reservoir, river embankment.

Background technology

Water is origin of life, is indispensable resource in existence.Water is liquid without solid shape at normal temperatures, can only be kept in container.In order better to utilize water resource, manage natural water, the mankind have manufactured the embankment in various reservoirs, river ... allow water stores at the reservoir on ground according to actual needs, flow in the embankment in river course, allow the water be mankind's service for life.Due to heavy rain, the wall of the many reasons reservoirs such as flooding, the embankment in river often can damage, and do not have the effect of holding management of water.The wall of reservoir, once the embankment in river loses the function of holding management of water, a large amount of water will, from reservoir, flow out in river course, enters the city outside the outer river levee of reservoir, Plain forms the floods that flooding causes human society.Floods, not only serious threat people's life of flood safety.Cause huge property loss, and socio-economic development is produced to far-reaching harmful effect.Though having become the important public safety of countries in the world guarantee social stability and economic development, control floods ensure cause.But it is difficult eradicating.So far floods are still a kind of natural calamity having the greatest impact in the world.Cause great loss to the mankind's lives and properties.Ran into heavy rain in the past, flooding reservoir wall, river embankment damages, a large amount of water flows out from reservoir bank of river the farmland of destroying by rush of water,, because leak in order to block rapidly reservoir river levee it is pressed for time, people can only be from reservoir wall when in the house, fetch earth or other charges near of river embankment, the place that leaks that is filled into reservoir wall, river embankment with got soil or charges, stops a leak, and increases embankment, with prevent a large amount of water flow out from reservoir bank of river after the farmland of destroying by rush of water, house forms floods.Due to reservoir wall, embankment the leak environment at place in river is generally all very poor, conventionally can not be with large-scale machinery, and this just need to carry the charges such as earth with a large amount of manpowers.Leak stopping, the work of increasing embankment is very dangerous inconvenient again.Particularly near the place that leaks without earth, when desirable without charges, can only see that helplessly current rush larger and larger by breach, cause floods to occur, be at a complete loss as to what to do.These problems could not be resolved so far.Find one can utilize reservoir, the local existing resource in river course, the safety quick place that leaks of blocking reservoir wall, river embankment before floods occur, increase embankment and prevent that a large amount of water from flowing out from the low-lying place of these embankments that leak the farmland of destroying by rush of water, house, the apparatus and method that form floods are world today's water conservancy circle urgent need to solve the problems.

Summary of the invention

The object of flood-prevention leakage-stopping device of the present invention is to provide one can utilize the local existing resource of reservoir, river course, and the breaking-up of blocking rapidly reservoir wall, river embankment before floods the occur place's leak that leaks, increases low-lying place embankment and prevent floods, device easy to use.

The principle of flood-prevention leakage-stopping device of the present invention is to be based upon on the basis that liquid exists pressure (Pascal's law).Pascal's law as you know: be added in the pressure on liquid or the gas in airtight container, can be transmitted to all directions by liquid or gas according to its original size.According to a water-filled airtight container for Pascal's law, and make its inner certain pressure that keeps.Because water has weight, the water pressure of the inside of container can act on again chamber wall, and the masterpiece used time is not easy distortion to the container that there is a water pressure inside outside.In the time that the pressure of internal tank water is greater than the impulse force of the place's water that leaks of reservoir wall, river embankment, container is placed on to the place that leaks of reservoir wall, river embankment, low-lying place, just can block reservoir wall, the place of leaking of river embankment or the current at low-lying place.Prevent that floods from occurring.

Flood-prevention leakage-stopping device of the present invention has directly utilized reservoir, the local existing water resource in river course, and the safety quick breaking-up place leak of blocking reservoir wall, river embankment of energy, prevents that a large amount of water is from the low-lying outflow of reservoir bank of river, forms floods.

Flood-prevention leakage-stopping device of the present invention is to complete by following method: well-known, one way valve can not reverse flow be crossed liquid, and two one way valves are housed on the housing of a sealing.Be respectively water feeding one-way valve, go out water one-way valve.Mix up in advance the water inlet water outlet hydraulic pressure of two one way valves, the discharge pressure that goes out water one-way valve should be less than the liquid maximum pressure that enclosure interior can be born.Hydraulic pump is by water feeding one-way valve toward water filling in housing, and in the time that hydraulic pressure in housing is greater than the pressure of water one-way valve, water can be discharged automatically from going out water one-way valve.Water-filled housing is placed on to the reservoir bank of river low-lying place of place that leaks, has weight after being full of water, inner have again hydraulic pressure to support the housing that can not be out of shape just to have become to block water from the leak device of low-lying place outflow of reservoir bank of river.Having reached requirement of the present invention provides one can utilize reservoir, the local existing resource in river course, blocks rapidly the place that leaks of reservoir wall, river embankment before floods occur, and low-lying place current, prevent floods, object easy to use.The housing of flood-prevention leakage-stopping device can be with various watertight materials as waterproof canvas, rubber, plastics, the making such as steel plate.
