Abstract

The utility model discloses a sludge-sand removing apparatus for river reservoirs. The utility model can automatically remove sludge-sands on river beds to avoid floods caused by the blockage of river channels. The sludge-sand removing apparatus comprises a main pipe which is arranged under a river bed, a vertical pipe which is connected with the main pipe and is upwards led out of a warning water level, and a spraying pipe which is embedded on the main pipe, wherein the end head of the spraying pipe is near the vertical pipe and is upwards extended near a water level, and on the main pipe, both sides of a spraying hole for the spraying pipe is provided with small holes for enabling sludge-sands spayed down by the spraying pipe to enter the main pipe through the small holes. The lower half periphery of the main pipe is laterad connected with a sludge-sand discharging pipe which extends out of a dam, and the discharge of sludge-sands is controlled by a valve on the sludge-sand discharging pipe.

Description

The rivers fine sediment of reservoir amasss husky cleaning equipment

One, technical field: the utility model belongs to the cleaning equipment of silt under water in the hydraulic engineering.

Two, background technology: the silt under water of rivers and lakes is washed into the downstream deposition along with current trickle all the year round from the upstream, the riverbed is constantly raise, and will overflow in case flood takes place.For a long time, dangerous situation one is repaired the dykes and build dams to people, stops up a loophole, and year after year, forms the riverbed and increases, and dykes and dams also increase, and form the overhead hanging river in riverbed at last, but do not clear up the riverbed, the reliable measure that the riverbed is reduced.

Three, summary of the invention: the utility model has designed a kind of long-pending husky cleaning equipment of rivers fine sediment of reservoir of clearing up riverbed silt.This cleaning equipment is connected to form by the pipeline of some different bores, is arranged on the position, riverbed.The trunk line Parallel to the flow direction is auxilliary to be located at below the riverbed, and descending pipe protrudes upward the water surface, highly arrives warning line, and bottom and trunk line are connected.Some row's sand tubes that Parallel to the flow direction tilts are drawn downwards simultaneously again in the pipe shaft Lower Half in the trunk line both sides.Row's sand tube stretches out outside the dykes and dams, on the pipe shaft outside dykes and dams gate is housed.Trunk line upper half tube wall upper edge axis direction has a few row's apertures, is embedded with playpipe on the tube wall in per two row's aperture centre positions, and the spray-hole on the playpipe is towards the trunk line periphery.Playpipe is upwards drawn near descending pipe and is highly arrived lowest water level, and the diameter at close mouth of pipe position enlarges gradually.The ventilating pipe upper end adjacent with descending pipe exceeds peak level, and the lower end communicates with the trunk line inner chamber.

This silt cleaning equipment is discharged the silt in riverbed automatically by water flow pressure with water, removed the sorrow that the riverbed constantly increases, and also has the flood discharge function simultaneously.

Four, description of drawings: Fig. 1 is the structural representation of the long-pending husky cleaning equipment of rivers fine sediment of reservoir; Fig. 2 is a trunk line cross section sectional view.

Five, the specific embodiment: as shown in Figure 1, Parallel to the flow direction is laid the descending pipe (1) that trunk line (3) and trunk line join and is protruded upward to the warning line height below the riverbed, and descending pipe can be vertical or tilt to the inflow direction.In case flood occurs, descending pipe can play flood discharge effect ventilating pipe (11) upper end adjacent with descending pipe than descending pipe height, and the top hangs up warning mark, prevents to navigate to bump, and ventilating pipe lower end and trunk line (3) are connected, and work to discharge inner air tube.Axis direction has a few row's apertures (8) in the tube wall upper edge of trunk line upper half, and the aperture of aperture inwall is greater than the aperture of outer wall, is beneficial to that sand grain enters trunk line and not by clamping stagnation blocking pipe hole.Be embedded with a playpipe (10) at per two tube walls of arranging the trunk line in aperture centre positions, spray-hole (9) is arranged towards the trunk line periphery on the playpipe, playpipe is upwards drawn near descending pipe (1) and is highly arrived lowest water level, and the diameter at close mouth of pipe position enlarges gradually.Because playpipe head (2) exists water-head and mobile hydraulic pressure with injection pipe shaft (10), the water in the playpipe is sprayed from spray-hole, the silt in loosening riverbed makes it to enter in the trunk line with the aperture (8) of current by trunk line.Some row's sand tubes (4) that Parallel to the flow direction tilts are drawn downwards simultaneously again in the pipe shaft Lower Half in the trunk line both sides.Row's sand tube stretches out outside the dykes and dams, and gate (5) is housed on the pipe shaft outside dykes and dams, and the silt in the starting gate, trunk line is promptly discharged outside the river course from row's sand tube (4) with current.Beyond the gate of row's sand tube, pipe shaft is provided with the desilting mouth and the transparent window (6) of band closing cap (7).If silt deposition in row's sand tube is stopped up, can clear up by the desilting mouth.Arrive as flood, can release the part flood by vertical pipeline (1) and row's sand tube (4) when river level is higher than warning line, alleviate danger.Be provided with filter screen at vertical pipeline (1) and playpipe head (2), prevent that foreign material from entering pipeline and stopping up.This silt cleaning equipment also can be used for reservoir desilting.Trunk line, vertical pipeline, desilting pipeline can be determined its caliber size according to actual needs, also trunk line and row's sand tube can be made flexible connection, will arrange sand tube and give and be located at easy deposition Shahe section.The trunk line part can move on the river course, arranges husky desilting piecemeal.Trunk line is fixed with cable wire after installing on the riverbed.

Claims

1, the long-pending husky cleaning equipment of rivers fine sediment of reservoir is that pipeline by some different bores connects to form, be arranged on the equipment at position, riverbed, it is characterized in that: trunk line (3) is laid on below the riverbed face, and descending pipe (1) protrudes upward the water surface, highly arrive warning line, the bottom is communicated with trunk line; Some row's sand tubes (4) that Parallel to the flow direction tilts are drawn downwards simultaneously again in the pipe shaft Lower Half in the trunk line both sides, and row's sand tube stretches out outside the dykes and dams, and gate (5) is housed on the pipe shaft outside dykes and dams; The upper half tube wall upper edge axis direction of trunk line (3) has a few row's apertures (8), tube wall in per two round centre positions is embedded with a playpipe (10), spray-hole (9) is arranged towards the trunk line periphery on the playpipe, playpipe head (2) upwards draws near descending pipe (1), highly arrives lowest water level; Ventilating pipe (11) upper end adjacent with descending pipe (1) exceeds peak level, and the lower end communicates with trunk line.
