Description

Reservoir desilting system

Technical field

The present invention relates to reservoir equipment technical fields, more particularly, to a kind of reservoir desilting system.

Background technique

Reservoir is one of the engineering measure that China's flood control is widely used.Building in flood control zone upper river appropriate location can adjust The multiple purpose reservoir of flood storage water cuts down the crest discharge for entering downstream river course, reaches deduction and exemption using reservoir capacity water conservation The purpose of flood damage.Sometimes, natural lake is also referred to as reservoir (natural storage).Reservoir scale usually presses the division of storage capacity size, It is divided into small-sized, medium-sized, large-scale etc..

According to service condition, the mud needs in reservoir are periodically cleared up.

Currently, reservoir desilting mostly uses greatly do mechanization operation, to need to consume a large amount of man power and material, and used Mechanical equipment it is more heavy and complicated.For small reservoir, this desilting mode is not ideal enough.

Summary of the invention

The object of the present invention is to provide a kind of reservoir desilting system, it has structure simple, easy for installation, sand-flash effect compared with Good feature.

The technical scheme adopted by the invention is that: reservoir desilting system is cleared up for the silt to reservoir bottom, should The right part of reservoir has dam, and the reservoir desilting system includes:

Inner tube, the left part of inner tube are located inside the silt and have sand inlet on the left part side of inner tube, meanwhile, inner tube Right end be fixed on the lower left side face of the dam；

Outer tube, the left end of outer tube are fixed on the lower part right side of the dam, and the right end of outer tube is equipped with sand excluding valve；

And

The left end of the right end connection outer tube of inner tube；

Inner and outer tubes are in right low left high shape.

The right end of the outer tube is connected with bend pipe, and the downward opening of the bend pipe is located in an overflow basin, on the overflow basin Portion's opening, lower part closing.

The opening of the bend pipe is supported by pillar in basin.

The lower part of the outer tube is equipped with several support rods.

Said inner tube is telescopic tube.

Said inner tube includes at least two unit pipes to link together, and the right part positioned at the unit pipes of left is inserted in position In in the left part of the unit pipes of right, and the right part for being located at the unit pipes of left is equipped with positioning pin, the list positioned at right The strip groove that the left part side wall of first pipe is equipped with and positioning pin matches, meanwhile, sand inlet is located in the unit pipes of leftmost.

Branch pipe is communicated on the side wall of said inner tube, branch pipe, which is equipped with, divides sand inlet.

The branch pipe is telescopic tube.

The invention has the advantages that compared with the prior art: structure is simple, easy for installation, and sand-flash effect is preferable.This The sand inlet of the inner tube of the reservoir desilting system of invention is in silt, once the sand excluding valve on outer tube is opened, then inner tube Pressure difference is formed with outer tube, silt can be expelled directly out.Simultaneously as desilting system is using pipeline as main component, so Structure is by a relatively simple, does not need to carry out a large amount of native stone construction, and assembly difficulty is relatively small.

Detailed description of the invention

Present invention will be further explained below with reference to the attached drawings and examples:

Fig. 1 is the front sectional view of the embodiment of the present invention；

Fig. 2 is the main view of unit pipes cooperation of the invention；

Fig. 3 is the top view of inner tube and branch pipe cooperation of the invention.

Specific embodiment

Embodiment, as shown in Fig. 1 to Fig. 3: reservoir desilting system carries out clearly for the silt 200 to 100 bottom of reservoir The right part of reason, the reservoir 100 has dam 300.

Concretely, which includes the components such as inner tube 10, outer tube 20.

Wherein:

The left part of inner tube 10, which is located on 200 inside of silt and the left part side of inner tube 10, has sand inlet 11.Into sand Mouthfuls 11 are not suitable for excessive, and the flow area of usual each sand inlet 11 is 100-200mm².For example, sand inlet 11 is strip Or circle hole shape.Obviously, sand inlet 11 is multiple.Meanwhile the right end of inner tube 10 can be fixed on the dam by components such as flanges On 300 lower left side face.

The left end of outer tube 20 can be fixed on the lower part right side of the dam 300 by components such as flanges, and outer tube 20 Right end be equipped with sand excluding valve 21.

The left end of the right end connection outer tube 20 of inner tube 10.Certainly, inner tube 10 can be multiple, outer tube 20 also can be multiple, Inner tube 10 can be realized two-by-two with outer tube 20 and is connected at this time.

Inner tube 10 and outer tube 20 are in right low left high shape.

In this way, when needing to clear up silt, it is only necessary to open sand excluding valve 21, then inner tube 10 and outer tube 20 realize pressure Difference, silt can voluntarily flow out, more convenient and simple.

Optimization:

The right end of outer tube 20 is connected with bend pipe 22, and the downward opening of the bend pipe 22 is located in an overflow basin 30, the overflow 30 upper opening of basin, lower part closing.Overflow basin 30 can for using iron plate carry out welding back wall at it is rectangular.In this way, in sand discharge When, there can be water first in overflow basin 30, water is closed the outlet of bend pipe 22, avoids enter into unnecessary air.Meanwhile Overflow basin 30 is also conducive to the fixation of the end of outer tube 20.

The opening of bend pipe 22 is supported by pillar 221 in basin.That is, convenient for the opening of bend pipe 22 and the bottom of overflow basin 30 With certain gap.

The lower part of outer tube 20 is equipped with several support rods 23.In this way, convenient for installing outer tube 20 on not smooth enough ground, and Conducive to the gradient for forming outer tube 20.

Continue to optimize:

Inner tube 10 is telescopic tube.As shown in connection with fig. 2, in the present embodiment, inner tube 10 includes at least two to link together Unit pipes 101 are inserted in the left part of the unit pipes 101 of right positioned at the right part of the unit pipes 101 of left, and are located at The right part of the unit pipes 101 of left is equipped with equipped with positioning pin 102, positioned at the left part side wall of the unit pipes 101 of right The strip groove 103 to match with positioning pin 102.Positioning pin 102 can be screw also can be with for the column of welding, positioning pin 102 It is slided in strip groove 103, the extending direction of strip groove 103 must be the same in the extending direction of unit pipes 101.That is, passing through pumping The scalable of inner tube 10 can be realized in drawing.Meanwhile sand inlet 11 is located in the unit pipes 101 of leftmost.In this way, convenient for better Adapt to the actual conditions in reservoir.

In addition:

In order to extend dredging area, branch pipe 40 is communicated on the side wall of inner tube 10, branch pipe 40, which is equipped with, divides sand inlet 41.Branch Pipe 40 can be in dendroid expansion distribution.

Branch pipe 40 is also telescopic tube.For example, branch pipe 40 is equally made of the unit pipes that end is nested together.

The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations Technical field, be included within the scope of the present invention.
