Abstract

The utility model discloses reservoir branch course desilting equipment, which is characterized in that one end of a desilting pipe is provided with a sand inlet, and the other end is provided with a sand outlet; the sand inlet is arranged at sludge in the upstream of a dam, the sand outlet is arranged in the downstream of the dam, and the sand inlet is shaped like a hopper. The reservoir branch course desilting equipment is adopted, so the desilting operation is continuous, energy does not need to be consumed, the environment-friendly and safe effects are realized, and the maintenance is facilitated.

Description

Reservoir shunting sand discharge equipment

Technical field

The utility model relates to hydraulic engineering apparatus field, is specifically related to a kind of sand discharge equipment.

Background technology

The dam of building on river is at present more and more, and in dam flood retention retaining, due to the destruction of upstream vegetation, a large amount of silt is rushed to dam place, and long-term accumulation can cause reservoir silting, and the water-holding capacity of reservoir declines.Present normally used way is to hold to arrange clearly muddy method, carry out sand discharge in flood season, such way has been alleviated the harm of mud to reservoir to a certain extent, but husky amount is huge when unified discharge, certain destruction is caused in downstream, and can not tackle the problem at its root.

Utility model content

In view of problems of the prior art, the utility model provides a kind of reservoir shunting sand discharge equipment, and sand discharge pipe one end is provided with sand inlet, the other end is provided with sand outlet, sand inlet is arranged on mud place, dam upstream, and sand outlet is arranged on dam downstream, and sand inlet is funnel-form.

Owing to sand discharge pipe being embedded in to reservoir bottom, and arranging of sand discharge pipe be angle of inclination, and high downstream, upstream is low, utilize gravity can make silt enter in sand discharge pipe, from sand outlet, silt is discharged to dam downstream, without consuming the energy, environmental protection, sustainability are strong, needn't disposable a large amount of sand discharges.

In some embodiments, sand inlet is provided with screen pack and entrance gate.Screen pack is set and can prevents that larger article from falling into desilting pipeline, prevent silting, destroy inner-walls of duct, when entrance gate is closed, can repair inner-walls of duct, prevent that water from flowing in sand discharge pipe.

In some embodiments, the quantity of sand inlet is multiple.Because the distributed number of sand inlet is many and each sand inlet apart from each other, adopt multiple tracks sand discharge, can effectively the silt in dam be discharged to downstream or both sides, riverbed.

In some embodiments, the wire side of screen pack is welded by steel bar.The netted filtering net being welded into by steel bar can be discharged the large part thing in reservoir, avoids entering sand discharge pipe, thereby destroys the inwall of sand discharge pipe.

In some embodiments, entrance gate is motor-operated control valve.The motor-operated control valve that the utility model adopts, can realize remote control, can control in real time according to the actual conditions of silt in reservoir.

The reservoir shunting sand discharge equipment that the utility model adopts, sand discharge continues, without consumed energy, Environmental Safety, easy to maintenance.

Brief description of the drawings

Fig. 1 is the structural representation of the reservoir shunting sand discharge equipment of a kind of embodiment of the utility model;

Fig. 2 is the cross section structure schematic diagram of the A-A in the utility model Fig. 1.

Detailed description of the invention

Below in conjunction with Figure of description, the reservoir shunting sand discharge equipment that the utility model is provided is described in more detail.

As depicted in figs. 1 and 2, reservoir shunting sand discharge equipment, comprises the sand discharge pipe 1 of being located at reservoir riverbed bottom or limit, riverbed massif, and the pipeline of sand discharge pipe 1 can be concrete duct, the pipeline that concrete duct can be connected one by one for more piece or directly build the pipeline forming; The pipeline of sand discharge pipe 1 can be also plastic conduit or other types pipeline; Sand discharge pipe 1 one end is provided with sand inlet 2, the other end is provided with sand outlet 3, sand inlet 2 is arranged on mud place, dam upstream and inhales beach volleyball silt, sand inlet 2 distinguishes with reservoir filling, the quantity of sand inlet 2 is multiple, the irregular mud place, dam upstream that is distributed in, and sand outlet 3 is arranged on dam downstream, therefore sand discharge pipe 1 is angle of inclination laying in bottom, reservoir riverbed, can utilize gravity sand discharge.Sand inlet 2 is funnel-form, facilitate silt to enter in sand discharge pipe 1, sand inlet 2 is provided with screen pack 4 and entrance gate 5, the wire side of screen pack 4 is welded by many crisscross steel bars, screen pack 4 can effectively filter out the large piece article in mud, prevents from entering in sand discharge pipe 1, resulting in blockage or destroying inner-walls of duct.

Entrance gate 5 is motor-operated control valve, and motor-operated control valve can be realized Long-distance Control, in the time that sand discharge pipe 1 occurs stopping up or be damaged, can close entrance gate 5, rushes to repair in time.

When normal operation, open entrance gate 5, silt enters in sand discharge pipe 1 by multiple tracks sand inlet 2, utilizes gravity factor, and silt tumbles naturally, by sand discharge pipe 1, silt is drained into downstream part.The reservoir shunting sand discharge equipment that the utility model adopts, sand discharge continues, without consumed energy, Environmental Safety, easy to maintenance.

The above is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some similar distortion and improvement, within these also should be considered as protection domain of the present utility model.
