The utility model relates to a water power sand discharge device. The utility model is used for reducing the damage of the mud and the sand of the water flow on the flow passage components of the hydraulic turbine. The utility model is characterized in that a sand discharging pipe (4) is communicated with a suction flexible pipe (3) through an inserting pipe (5); the water inlet end of the sand discharging pipe is provided with a depth adjustment rod (7), and the water outlet end of the sand discharging pipe is a weir type water outlet (1); the suction flexible pipe and the inserting pipe are provided with an opening valve (2) and a three-way valve (6). The valve is opened and closed, and the siphon mud and sand drainage is formed. The utility model achieves the purposes that the mud and sand passing the hydraulic turbine is reduced; the abrasion of the water turbine is alleviated. The utility model has the advantages that the structure is simple; the sand discharging effect is good; the water consumption is saved; the utility model can be used as the sand discharging device of the diversion canal of the hydroelectric station, and can also be used as the sand discharging device for broad water areas.

Description

Power station water power sand discharge unit
The utility model belongs to the waterpower sand discharge apparatus.
In channel water channeling type water-power plant, silt is provided with larger sand trap mostly to the damage (water machine sand erosion) of water turbine overflowing component in the current in order to alleviate, and drains the silt of precipitation.Its weak point is a sand trap expenditure of construction height, and it is low to arrange husky efficient, and water consumption is big, and arranges husky scope and be limited to the sediment ejection opening near zone more.
Provide a kind of row husky effective, water consumption is economized, sand discharge apparatus simple in structure, and to reduce machine silt, prolonging the hydraulic turbine life-span is the purpose of this utility model.
Structure of the present utility model as shown in the figure.Accompanying drawing is a waterpower sand discharge apparatus schematic diagram, wherein: 1. row's sand tube outlet; 2. opening valve; 3. inhaling hose; 4. row's sand tube; 5. intubate; 6. three way cock; 7. depth adjustment bar; 8. laterally move wheel; 9. stir husky device; 10. vertically move wheel.
Characteristics of the present utility model are that row's sand tube (4) is connected with inhaling hose (3) by intubate (5), the water inlet end of row's sand tube has depth adjustment bar (7), there is weir formula delivery port (1) water side, open valve (2) and triple valve (6) are arranged on inhaling hose and the intubate, pass through valve opening and closing, form siphonage, so that the shoal materials of sucking-off different depth.
Husky device (9) is stirred in the lower end of depth adjustment bar, is used to stir the silt particle of precipitation, and Lian Shui band sand is discharged outside the canal, improves the husky efficient of row.
Row's sand tube is the rigid pipe of D100~200 different series from the suction side to peak, and remainder is a flexible pipe.
Embodiment of the present utility model is:
Row's sand tube (4) is rigid pipe from the suction side to peak, the steel pipe of promptly common D100~200 (general middle-size and small-size power station D100~125 pipes get final product), arranging the sand tube remainder is flexible pipe, as vacuum hose or tolerate the hard plastic tube of 5m left and right sides water column vacuum.It and intubate (5) are chewed with steel plate clamp clamping (or steel wire is tightened) by pipe and are made it air tight, must make airtight test after the connection, make it air tight under 4~5m water column vacuum.
The depth adjustment bar is by being welded with two suspension hooks in row's sand tube both sides, hang wire rope on the suspension hook and manually smash chain and link, by manually smashing the height (promptly arranging the husky degree of depth) that chain hoists or reduces whole row's sand tube on the support, after highly determining, utilize the gripping sleeve of pipe both sides that it is tightly dead, stable to guarantee that he works in moving water.
Stirring husky device mainly is made up of the small-sized speed changer that stirs miniature hydroturbine in sand table and the row of the being contained in sand tube vertical section steel pipe and be connected the two of direct stirring precipitated mud and sand.Miniature hydroturbine utilization is arranged the part water energy in the ascending current in the sand tube and is rotated, and stirs sand table by drive behind 8~25 times of moments of torsion of speed changer increase and carry out work.
During installation, an end of row's sand tube is stretched in the canal, the other end then strides across the canal bank, stretches to lower, and outlet must be lower than in the channel more than the water surface 3m.
After the draining zone is selected, at first inhaling hose (3) is submerged, automatic water-filling, emptying is air wherein, and it is appropriate to stride across the channel installation again, opens valve (2) then, makes pipe (3) form syphon work; Simultaneously, form certain vacuum with intubate in the larynx section of pipe in (3), then turn three way cock (6) makes pipe (3) be communicated with managing (4), and the gas that will manage in (4) pumps, and makes it also form syphon work.After the row's for the treatment of sand tube is working properly, again valve (2) cuts out, make pipe (3) break-off.
Row's sand tube connects with vertical, horizontal mobile wheel (8), (10) mutually by attachment bracket.Then utilize the swing of the flexible pipe of yaw on canal or the vertically displacement of moving the row's of finishing sand tube of wheel when laterally moving.
Laterally, vertically moving moving of wheel can be manual, also can laterally, vertically respectively adorn two micro-machines on the wheel and make it to drive, like this, the operating position, plane of the row's of change sand tube (4) easily.
Three way cock (6) is threaded to pipe (4) position that is connected with atmosphere, waterpower sand discharge apparatus cutout and out of service immediately.
Also the plane travel mechanism in the waterpower sand discharge apparatus can be changed into float-type mechanism makes it in bigger water surface work with rope or anchor chain location.
The utility model has the advantages that simple in structurely, row is husky effective, and water consumption is husky below 50% of water consumption of sand basin.
Can be used as the sand discharge apparatus in the flume of power station, also can be used as the sand discharge apparatus in wider waters.
