Abstract

The utility model discloses a sand discharging apparatus for reservoirs, which is composed of a pipeline crossing on the dam; one end of the pipeline is arranged in the water at the inner side of the dam, and the other end is provided out of the dam. Two valves and a water filling inlet are arranged on the pipeline, and the valve at the inner side of the dam is positioned at the water surface point in the dam body, and the valve at the outer side of the dam is positioned at low water surface out of the dam body; the water filling inlet is positioned at the dam top point. The utility model used in the existing reservoirs solves the problem of sand sedimentation and generates power; the sand discharging apparatus for reservoirs depends on the potential energy of water and the principle of siphon, has the advantages of simple structure and easy operation, efficiently solves the sand sedimentation of the reservoirs, and is suitable for small-sized reservoirs and pond dams.

Description

The husky device of reservoir spoil disposal

One, technical field

The utility model belongs to the hydraulic engineering supporting facility, is specifically related to the husky device of a kind of reservoir spoil disposal.

Two, background technology

Along with the minimizing gradually of forest cover, the sand content in river is on the increase, and the sedimentation phenomenon of reservoir is on the rise, and causes storage capacity to reduce, and reservoir can not be played a role.Early stage reservoir does not have the husky system of spoil disposal, and the sedimentation problem can not get solution, particularly some small reservoirs, dyke always, and under the bad situation of water and soil conservation, more than ten years even several years will be scrapped by the silt alluvial.In addition, the small power station in rural area utilizes relatively poor, and some mountain area of having built reservoir is being main fuel with the faggot also, has more increased the destruction of vegetation.Utilizing existing water conservancy projects generating also is a current important topic.

Three, summary of the invention

The purpose of this utility model provides the husky device of a kind of reservoir spoil disposal, and it can use in existing reservoir, solves the problem of sedimentation, also can be used for generating.

The husky device of reservoir spoil disposal is made of the pipeline on dam, and pipeline one end places the water of the inboard reservoir of dam, and the other end places outside the dam; Two valves and a water filling port are housed on pipeline, and the inboard valve in dam is positioned at water in dam face place, and the outside, dam valve is positioned at the dam body outside and is lower than water surface place, and water filling port is positioned at the dam crest place.

During use, close the valve of both sides earlier, water filling port in the middle of opening then, water filling in pipeline, after filling with, water closes water filling port, open inboard valve in dam and the outside, dam valve then successively, because siphonage, the mixed liquor of the water-bed mud of locating, sand, water flows to lower outside the dam via pipeline on the dam in.

The utility model relies on the potential energy of water, utilizes siphon principle, has simple in structurely, implements the characteristics that are easy to, and can solve the reservoir deposits deposition problems effectively, especially to small reservoir, dyke, acts on fairly obvious.

Five, the specific embodiment

The husky device of reservoir spoil disposal is made of the pipeline on dam, the pipeline that reaches the outside on the dam adopts iron pipe 6, the pipe section that extend in the water adopts bellows 3, the husky device 1 of spoil disposal is housed in the termination of bellows, the husky device 1 of spoil disposal places water-bed silt 2 places during work, the husky device 1 of spoil disposal has cylinder-like shell 20, there is an axis at the center, there is helical blade 21 at this rear portion, front end is equipped with stirring-head 22, and when current passed through cylinder 20, helical blade 21 drove stirring-heads 22 and rotates, the mud at the bottom, husky stirring are got up, in the suction pipe.Valve on the pipeline was in the dam body inboard and the outside in 4,7 minutes, and water filling port 5 is positioned at the dam crest place.The silt that pipeline is discharged flow in the sedimentation basin 8, and silt is through precipitation, pass through plant filtering area 9 again after, discharge the water of cleaning.The utility model can also be used for generating, as shown in Figure 2, TRT is identical substantially with the husky device of spoil disposal, pipeline 14 is an iron pipe, the inboard valve 11 in dam and dam outside valve 15 and dam crest water filling port 12 are also arranged on the pipeline, but inboard termination, its dam is positioned at water district 10, and there is screen pack this water district 10, makes solid matter can not be drawn onto in the pipeline; There is branch nuchinal organ 16 termination, the outside, dam, divides nuchinal organ 16 that pipeline is divided into several roads, on the pipeline of every road valve 17 is arranged all, and the hydraulic turbine 19 is equipped with in the outer end of each pipeline, and each hydraulic turbine 19 drives generator 18 work.Its course of work is: at first valve-off 11,15, open water filling port 12, after the pipeline fills with water, close water filling port 12, open valve 11, valve 15 successively, because of siphonage, divide nuchinal organ 16 water inlets and the certain pressure effect is arranged, open valve 17, the hydraulic turbine 19 rotates, drive generator 18 and rotate, generator 18 output electric energy.

The utility model is wanted close inspection in installation process, operating process will conscientiously be fulfiled each step, as the case may be, use concrete material, tubing reasonably, want suitably the position of valve, the connection of each parts will be carried out by standard, so that the utility model performance best efficiency.
