Reference book attached drawing 3 and attached drawing 4 are the utility model second embodiment.A kind of water conservancy water storage loop structure,
Including cofferdam 1', hydraulic water pump 2' and water tower 3', hydraulic water pump 2' is set in the 1' of the cofferdam, which has water inlet
Mouth 11' and water outlet 12', water flow drive hydraulic water pump 2' to rotate by the water inlet 11' of cofferdam 1', keep part water flow logical
It crosses Water intake for water tower channel 31' and flows into water tower 3', remaining water flow is connected to by exhalant canal 32' with water outlet 12', thus from going out
It is discharged in the mouth of a river.Wherein, hydraulic water pump 2' includes coaxially connected large impeller 21' and small impeller 22', large impeller 21'
Between water inlet 11' and small impeller 22', small impeller 21' is located at Water intake for water tower channel 31' and exhalant canal 32' crosses
Position.For example, refering to Fig. 4, water pumper large impeller 21' and small impeller 22' area ratio are 2:1, theoretically can be water level
Raise nearly 2 times, that is, 2 unit water flows are from H'(water inlet river surface and water outlet river surface difference in height) eminence falls drive waterpower
Water pumper, hydraulic water pump are again extracted into 1 specific discharge water the height of nearly 2H'.Certainly, hoisting depth is with promotion water at anti-
Than raising higher, water is smaller；Raise lower, water is bigger.It therefore, can be according to conveying distance and with the elevation at water, respectively
Hoisting depth needed for determining, installs the hydraulic water pump of corresponding lift, meets the needs of different elevation water.
The principle of hydraulic water pump will be described in detail below.Water flow is gathered at the water inlet 11' in cofferdam 1'
Collection forms potential energy with certain height of water level difference, after the gate when water inlet is opened, the potential energy be water tower into
Potential energy at aquaporin 31', the kinetic energy of exhalant canal 32' and loss, the i.e. energy conversion can be indicated with following formula: water inlet
Potential energy=(exhalant canal) kinetic energy+(Water intake for water tower channel) potential energy+loss.Also therefore, refering to Fig. 3, Inlet and outlet water is logical in order to prevent

It is arranged at the water outlet of exhalant canal 32', thus the potential energy of trans-utilization water inlet to greatest extent.
Further, which further includes water flow blind way 5', passes through drainage channel between the water flow blind way 5' and water tower 3'
51' connection, it is preferred that the drainage channel 51' is water pipe.Specifically, the effect of cofferdam 1' is to form water level inside and outside the 1' of cofferdam
Height difference first closes the gate of water inlet 11' at high tides, and 1' outer water level in cofferdam rises steadily, and water-head is continuous inside and outside the 1' of cofferdam
It increases.High water time opens the gate water inlet of water inlet 11', and most water, to inland lake, drives big lake surface by exhalant canal 32'
Water circulation.Meanwhile water flow drives hydraulic water pump 3' rotation, and part water flow is made to pass through Water intake for water tower channel 31' to water tower 3'.
Since the water level of water tower 3' is higher, can be transported to far with the speed for being faster than the water flow of exhalant canal 32' by draining channel 51'
The water flow blind way end 5' at place, and then water flow outbound flows from interior, takes the water of water flow blind way 5' to big lake surface, imports exhalant canal
It is recycled in 32'.Store up the gate of closing water inlet 11' after full water in inland lake.The outer water level of cofferdam 1' constantly declines after ebb, low tide
When, water-head is maximum inside and outside the 1' of cofferdam, and the gate for opening water outlet 12' discharges water, and allows water to be quickly discharged, drives the water body stream of inland lake
It is dynamic.The gate that water outlet 12' is closed when water level is preferably minimized, is ready for flood tide next time.It loops back and forth like this, completes water
Body exchange, so as to achieve the effect that water body treating, and just need not frequently change water after water quality has been got well, closed shutter,
To keep water landscape, environmental amenity degree is improved.Circulate the water of inland lake just with tidal range in the prior art, by
The water quality of lake surface closer from off-lying sea can only be improved in this kind of mode, for relatively going deep into the lake surface in inland, water body exchange is insufficient, water quality
It is unsatisfactory.The especially water flow blind way of corner can only carry out moisturizing since river is relatively narrow by the way of pipe laying.If
By pumping for water pump, the electricity charge are expensive.If only leaning on tidal range water delivery, drop is small, and water velocity is slow, requires height to the laying of pipeline, and
Those topographies are higher, farther away place is difficult to be sent to and water outlet is low, and water pipe is easy siltation.So this kind of the application designs
Structure can allow the maximum flow circuit of water body compared to the prior art, and without using electric power, structure
Simply, operation is carried out just with the energy of the Nature, not only clean and environmental protection, but also ecology can be improved.This kind of structure but also
It is a large amount of on the wetland of seashore, remote to become possible using seawater.Certainly, be equally applicable to seawater swimming pool, amusement on water project,
Raising fish and shrimp water supply etc..
