Description
Technical field
The utility model relates to a kind of device that reservoir sedimentation silt distributes again that drives, and is a kind of water conservancy project device, is that a kind of natural force that utilizes is intervened reservoir bottom institute silt, makes the silt device that flows away of stream downstream.
Background technology
Shoal materials is namely to begin the problem that occurs since the mankind begin to build reservoir in the reservoir.After repairing the dam and build the storehouse in the river, reservoir water level is stopped up high, and water surface gradient slows down, and flow velocity reduces, and sediment transport capacity significantly reduces, and impels most of silt alluvial in the storehouse.Its result not only causes the reservoir effective storage to reduce, and reduces emerging sharp benefit and flood control capacity, even will threaten reservoir application life and safe operation; The while reservoir sedimentation causes on the backwater end prolongs, and expansion is flooded and influence basin, and will threaten cities and towns, upstream, industrial and mineral and traffic safety; The silt alluvial of backwater end also can influence shipping; A large amount of alluvials of reservoir area silt may cause hazardous substances to be deposited on the bottom of the reservior, pollute reservoir and surrounding environment, and will become silted up and do not have the ground of laying eggs of fish, influence fish reproduction.The reservoir deposits problem is a worldwide ubiquitous problem, but China's reservoir deposits problem is particularly outstanding.This is because owing to serious soil erosion, the river sand content of China is generally all very high.Therefore, build reservoir at such heavily silt-carrying river, will inevitably produce Sedimentation Problems.The method that tradition is removed reservoir deposits is to use heavy mechanical equipment excavation reservoir to remove mud, but this method will spend lot of manpower and material resources.For this reason, whether can find a kind of strength of not using the mankind, but by power of nature, the reservoir bottom be intervened at the position of shoal materials easily, remove or prevent the alluvial of silt, this needs a kind of brand-new solution.
The utility model content
In order to overcome prior art problems, the utility model proposes a kind of device that reservoir sedimentation silt distributes again that drives.Described device utilizes wind-force and natural flows kinetic energy to produce and stirs, and is placed on the reservoir position of appointment.The water level fluctuation that wind-force produces and along with flowing naturally of current makes described device in the low swing up and down of water, increase the disturbance of bottom of the reservior current, impel shoal materials to start again and prevent that alluvial from taking place, thereby what change the bottom of the reservior assigned address dashes the silt characteristic, and removes silt in the Reservoir region with this.
The purpose of this utility model is achieved in that a kind of device that reservoir sedimentation silt distributes again that drives, described device comprises: the anchor point that arranges in the current upstream, described anchor point is connected by the solid bar of the vertically disposed system of anchoring rope and water (flow) direction, the solid bar of described system connects the connecting rod of arranging in length and breadth, connect a plurality of buoyancy body on the described connecting rod, form the buoyancy body array, each buoyancy body in the described buoyancy body array connects the degree of depth rope that has the folding and unfolding facility respectively, described each bar degree of depth rope connects the stirring volume array, described stirring volume array is made of the stirring body of extended spread or arrangement in length and breadth, and the stage casing of described each bar degree of depth rope is respectively equipped with single stirring body.
The beneficial effect that the utility model produces is: the utility model arranges the buoyancy body array and makes buoyancy body connect water-bed stirring volume array in the position of the easy shoal materials of reservoir, do not use any artificial power, the wave that utilizes wind-force to produce impels the buoyancy body array to drive stirring volume array generation fluctuation, utilize the mobile current of nature to impel simultaneously and stir volume array stirring current, reservoir bottom silt is risen under the effect of stirring current, washed away by current.Stir body and utilized the most basic fluid mechanics principle, impel the current of smooth flow to produce turbulent flow, remove silt.Owing to do not use any artificial power, can save a large amount of energy.Can use very cheap material owing to stir body simultaneously, buoyancy body array and the manufacturing of stirring array are also very simple, and whole installation cost is extremely low.Thus, the utility model uses the simplest device to change the water flow dynamic energy transform mode, increase the disturbance of assigned address current, thereby be implemented in and do not use any artificial power and by under the elemental situation, solved reservoir sedimentation silt this is time-consuming with conventional method, effort also is difficult to the problem that solves.
