Embodiment
Referring to Fig. 1 and Fig. 2, intake tower 2 is built near dam or the side of massif 1 in reservoir first, then in intake tower 2
Open up a water intaking groove 3, in water intaking groove 3 positioned at the two or more arranged below of reservoir water bit line 10 and the arrangement that is stepped point
Layer intake 5, one trash rack 4 is set in the water inlet of water intaking groove 3, and sets gathering sill 13 in the outside of trash rack 4,
The top of gathering sill 13 is provided with trash 9 before grid, just can be so layered by each according to reservoir River Dynamic observed case
The stratified pumping of intake 5, while all dirts before the grid of trash rack 4 are salvaged downwards along gathering sill 13 by trash before grid 9,
Ensure the Water quality in water intaking groove 3.Meanwhile, the elevation of dead water level 11 is provided with sand discharge and emptying in water intaking groove 3
Mouth 6, is discharged bottom of the reservior silt, deposit by sand discharge and drain 6, improves Water quality.Dirt mistake before the grid of trash rack 4
When many, all dirts before the grid of trash rack 4 can downwards be salvaged along gathering sill 13 by trash before grid 9, it is ensured that water intaking groove 3
Interior Water quality；The dirt for salvaging is deposited on waste platform 12, and trailer is by access bridge 8 by dirt by waste platform
12 transports appear on the scene.
The operation principle of trash 9 before grid：Referring to Fig. 1~7, first will be clear before grid along guide rail 17 by walking dolly 23
Dirty machine 9 is moved to the top of water intaking groove 3, then to oiling in hydraulic cylinder 25, stretches out the flexible push rod 27 of hydraulic cylinder 25, so that will
Arc is grabbed lid 24 and is opened；Now start trash lifting machine 19, trash 9 before slow decentralization grid makes before grid trash 9 along blocking
The gathering sill 13 in the outside of dirty grid 4 is moved down, while trash before grid 9 is moved down, the arc of opening grab lid 24 then to
Lower salvaging is wrapped in the dirt on trash rack 4, is grabbed due to hopper 34 and arc and osculum 36 is arranged with lid 24, downward
During salvaging, dirt is then all stayed in hopper 34, and when trash 9 is moved to the bottom of trash rack 4 before grid, dirt is beaten
The process of dragging for terminates.Now, the outside oil extraction of hydraulic cylinder 25, makes the flexible push rod 27 of hydraulic cylinder 25 retract, so as to arc is grabbed into lid 24
Close, prevent the dirt salvaged from dropping；At this moment, reverse starting trash lifting machine 19, trash lifting machine 19 passes through steel wire rope
Trash 9 is up-shifted to the top of intake tower 2 before pulling grid, and the dirt that will finally salvage is deposited on waste platform 12,
Dirt is transported appearance by trailer by access bridge 8 by waste platform 12.
Bypass the operation principle of suction gate 37：When needing to carry out stratified pumping or by sand discharge by stratified pumping mouthfuls 5
And drain 6 is when carrying out sand discharge and emptying, stratified pumping mouthfuls 5 or row can be completed by opening corresponding bypass suction gate 37
The keying work of husky and drain 6.Referring to Fig. 8~11, the present invention is provided with the water suction of up/down perforation in the center of valve seat 39
Pipe 44, the oral area in the upper end of suction hose 44 is provided with taper water check valve 43, and taper water check valve 43 is taken with being arranged on by cable wire 42
The gate lifting machine 38 at the top of tank 3 is connected.Because volume is much smaller for the opposite valve seat 39 of taper water check valve 43, therefore opening
Resistance to water-flow and negative pressure suffered by mantle shape water check valve 43 is also relatively small, so just can be light by gate lifting machine 38
Pine pulls open taper water check valve 43, current is entered in stratified pumping mouthful 5 or sand discharge and drain 6 by suction hose 44, eliminates water
The raw negative pressure of miscarriage；Taper water check valve 43 is carried after concora crush, in continuation, taper water check valve 43 is continued after being stuck in the lower end of pull bar 41
Move up, so as to open the valve seat 39 being connected with pull bar 41, complete bypass suction gate 37 opens door.Therefore, side of the invention
Logical suction gate 37 closes the working method that door, hydrostatic open door using dynamic water, opens taper water check valve 43 when Men Shixian is opened, after concora crush again
Open valve seat 39 to realize opening door, its lectotype selection capacity is small, but accident door, cleaning door can be played a part of.
