Description

A kind of tidal river auto purification type ecology is T-shaped draws/water fetching device
Technical field
The utility model belongs to hydraulic engineering field, particularly relates to that a kind of tidal river auto purification type is ecological T-shapedly draws/water fetching device.
Background technology
At present, in order to improve the demand of Water Environment in Urban Rivers and industrial and mining enterprises' water, water-supply method the most common and economic is exactly directly fetch water from contiguous river.By at riverbank excavation intake or water-drawing channel, outer river is introduced inland river or is drawn into water area.When in river of fetching water, sediment charge is higher, do not add direct the water intaking from river in process ground and will cause a series of contingency question, such as what amasss intake, damages intake equipment etc.
And traditional water-supply method directly cannot remove the silt in water when fetching water, this just needed before utilizing further water, sediment charge too high in water is removed by special sand-removal device (such as sand trap etc.), and the silt deposited also is needed to be processed by special approach, not only complex management, and later stage running cost is also very high.
Utility model content
The object of the utility model embodiment is to provide that a kind of tidal river auto purification type is ecological T-shapedly draws/water fetching device, be intended to solve traditional to draw/water fetching device not only needs special desilting facility, also must carry out special disposal to the silt after sedimentation, complex management, the problem that later stage running cost is high.
The utility model realizes like this, a kind of tidal river auto purification type is ecological T-shapedly to be drawn/water fetching device drawing/the left and right both wings of intake, arrange water-drawing channel respectively, tetrahedron permeable frame group is laid in water-drawing channel, water-drawing channel side utilizes riverbank, the groynes downstream together that opposite side utilizes the rubber dam filling water/gas be arranged on fixed station to be formed.
Further, when the water-drawing channel design diversion depth of water is less than 2 times of tetrahedron permeable frame height, one deck tetrahedron permeable frame can be laid, when designing the diversion depth of water and being greater than 4 times of tetrahedron permeable frame height, two-layer tetrahedron permeable frame can be laid.
Further, the length of the rod member of composition tetrahedron permeable frame can adjust according to actual conditions, and rod member material can adopt mixed earth, regenerated plastics, natural material, and the cross section of rod member can be square or circular.
The utility model is when fetching water, progressively flow rate of water flow is reduced by the tetrahedron permeable frame group arranged along journey at water-drawing channel, consume flow energy, when flow rate of water flow is less than the sedimentation flow velocity of silt, silt will deposit by automatic sedimentation, need not additionally utilize other measure again, whole process is without the need to manual operation, full ecological and environmental protection, in the non-water intaking time, then utilize the special flow-shape of formation, automatically the silt underwashing deposited during diversion is taken away, the clean husky process of current is automatically realized by physics mode, hostile environment and ecological problem can not be caused to water intaking river.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.There is not the innovation of method or software in the utility model.
Below in conjunction with drawings and the specific embodiments, application principle of the present utility model is further described.
Fig. 1 shows tidal river auto purification type of the present utility model and ecological T-shapedly to draw/structure of water fetching device, as shown in the figure, the utility model realizes like this, a kind of tidal river auto purification type is ecological T-shapedly to be drawn/water fetching device drawing/the left and right both wings of intake 1, arrange water-drawing channel 3 respectively, in water-drawing channel 3, lay tetrahedron permeable frame 7, water-drawing channel 3 side utilizes riverbank 6, and opposite side utilizes the rubber dam 4 filling water/gas be arranged on rubber dam fixed station 5 to form together groynes downstream.
Further, Figure 2 shows that in typical trapezoidal cross-section, the arrangement of tetrahedron permeable frame, when water-drawing channel 3 depth of water is less than 2 times of tetrahedron permeable frame 7 height, one deck tetrahedron permeable frame 7 can be laid, when the depth of water is greater than 4 times of tetrahedron permeable frame 7 height, two-layer tetrahedron permeable frame 7 can be laid.
Further, the length of the rod member of composition tetrahedron permeable frame 7 can adjust according to actual conditions, rod member material can adopt mixed earth, regenerated plastics, also natural material can be adopted, such as bamboo, when adopting bamboo, local silt is poured in thick bamboo tube, recomposition tetrahedron is placed in water-drawing channel, thus avoids adverse effect that is ecological to river course and current, environment, and the cross section of rod member can be square or circular.
Operating principle of the present utility model is as follows:
When fetching water in flood tide, current pass through from water-drawing channel 3, the tetrahedron permeable frame group be laid in channel progressively consumes flow energy along journey, reduce the sediment carrying capacity of current, when water-drawing channel 3 reaches sufficient length, just can impel the sediment settlement in water, thus reach the object removing silt in water.Current after T-shaped both wings purification enter collecting tray 2 by river conjunction, carry out drawing/fetching water in collecting tray 2 end by diversion facility or intake equipment.When the non-water intaking of ebb tide, by discharging a water/gas in rubber dam 4, reduce the height of rubber groynes downstream to 2/3 place of the depth of water, make the river outside water-drawing channel 3 climb over rubber groynes top and enter water-drawing channel 3, thus form stable spiral flow, the spiral flow formed fully can stir the silt in water-drawing channel 3, by the comparatively mass-flow flow velocity that ebb tide is formed, water-drawing channel 3 can be discharged rapidly stirring the silt got up, thus avoid the permanent alluvial in the channel of silt, affect diversion effect, after silt removes end-of-job, again toward water-filling or gas in rubber dam, in order to stop that outside silt carrying flow directly passes in and out collecting tray.
The utility model is when fetching water, by the progressively reduction flow rate of water flow of water-drawing channel along journey tetrahedron permeable frame group, consume flow energy, when flow rate of water flow is less than the sedimentation flow velocity of silt, silt will deposit by automatic sedimentation, need not additionally utilize other measure again, whole process is without the need to manual operation, full ecological and environmental protection, in the non-water intaking time, then utilize the special flow-shape of formation, automatically the silt underwashing deposited during diversion is taken away, the clean husky process of current is automatically realized by physics mode, hostile environment and ecological problem can not be caused to water intaking river.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
