Description
Technical field
The present invention relates to a kind of erection method of pollutant-blocking grate and the telescopic pollutant-blocking grate floating drum of grid, belong to Hydropower Plant
Preceding sewage blocking device technical field.
Background technology
In Hydraulic and Hydro-Power Engineering, in order to prevent larger dirt from entering generating set, normal power generation even destruction machine is influenceed
Group, pollutant-blocking grate often is set in intake upstream side.
Pollutant-blocking grate is made up of multiple floating drums being connected in series, floating drum both ends and the generating set intake both sides of series connection
Left and right buoyancy tank connection；Floating drum bottom is fixed with grid.Floating drum swims in the water surface, and grid is located at below the water surface, and floating drum is used to stop
The dirt of the water surface is swum in, grid is used to stop the dirt being suspended in below the water surface.
Existing grid is overall structure, and is welded on floating drum bottom.Existing overall structure can not hang down early stage in water storage
Stand on ground, the buoyancy tank of pollutant-blocking grate left and right ends can not be connected with floating drum, cause pollutant-blocking grate to enter working condition.Cause
This can only make floating drum to install pollutant-blocking grate after vertically bubbling through the water column above when reservoir area water storage reaches Installation Elevation at present, and
And operating personnel need to work inside water, add difficulty of construction, worker's life is also heavily affected safely.Arrived in reservoir area
Up to before normal pool level, the also non-installation of pollutant-blocking grate during water storage, now part dirt enters diversion by current
Generating intake region.
The content of the invention
, will it is an object of the present invention to provide a kind of erection method of pollutant-blocking grate and the telescopic pollutant-blocking grate floating drum of grid
Existing monoblock type grid and the mode of floating drum bottom welding are transformed into sublattice grid independent one by one, sublattice grid and floating drum side
Using the connected mode of grafting, first one group of floating drum can be thus connected in series early stage in water storage, water storage phase floating drum with
Water level rises, and is inserted when floating drum reaches certain elevation, then by single sublattice grid one by one in the guide groove of floating drum side；Can be
The interception to dirt is realized during water storage, further reduces the dirt into diversion and power intake region, it is existing to overcome
Technical deficiency.
The technical proposal of the invention is realized in this way：
A kind of erection method of pollutant-blocking grate of the present invention is that this method is that existing monoblock type grid is transformed into by one
The individual grid that individually sublattice grid are formed, guide rail is welded with each sublattice grid；Guide rail and the guide groove of floating drum side are slided and connected
Connect；When pollutant-blocking grate is installed before the water storage of reservoir area, floating drum is first lain in into the bottom surface in generating set water intaking epistome and floating drum is connected
Connection, then floating drum one end of series connection and the buoyancy tank positioned at generating set intake side are hinged again；Or because of actual landform feelings
Condition and floating drum can not be realized while when being connected with both sides buoyancy tank, the floating drum other end of series connection passes through steel wire rope and generating set
The buoyancy tank of intake opposite side connects temporarily, and after reservoir area starts water storage, as the reservoir area water surface raises, floating drum is also with water level
Rise, progressively tighten up buoyancy tank of the steel wire rope by floating drum close to opposite side, by floating drum and opposite side when water level reaches certain elevation
Buoyancy tank is hinged；Inserted when floating drum reaches certain elevation, then by single sublattice grid one by one in the guide groove of floating drum side；It is anti-
Only grid rocks in guide groove, and pressing plate is close on grid track with stationary grizzly by bolt device；When water level meets to pacify
During reload request, grid installation so can will as far as possible be reduced suspension pollutant and pass through pollutant-blocking grate in time with installation comprehensively.
For a kind of telescopic pollutant-blocking grate floating drum of grid of the invention of the above method, including floating drum and sublattice grid, float
Cylinder both ends are provided with articulated mounting；The sublattice grid side is provided with guide rail, and floating drum side is provided with guide groove；Guide rail on sublattice grid is with floating
Guide groove on cylinder is slidably connected.
It is high at least provided with a guide rail, rail height on the sublattice grid in the foregoing telescopic pollutant-blocking grate floating drum of grid
In sub- height of grid, guide rail bottom is concordant with sub- grating base and welds, and guide upper is located in guide groove and slided with guide groove and connected
Connect, guide rail top is provided with limiting plate.
In the foregoing telescopic pollutant-blocking grate floating drum of grid, the floating drum side is at least set provided with least two row guide grooves, each column
There are two guide grooves.
In the foregoing telescopic pollutant-blocking grate floating drum of grid, the floating drum between described two guide grooves is provided with least one fixation
Seat, fixed seat are provided with screwed hole, and screwed hole is connected through bolt with pressing plate.
In the foregoing telescopic pollutant-blocking grate floating drum of grid, the fixed seating is pressed in through bolt and led in guide rail both sides, pressing plate
Guide rail is fixed on rail.
By adopting the above-described technical solution, the present invention is compared with prior art, this invention takes two improvement projects,
First, existing monoblock type grid is transformed into single sublattice grid one by one, guide rail is welded with each sublattice grid.Using
The benefit of sublattice grid is to greatly alleviate the weight of grid, is convenient to operation.Second, existing grid is welded on floating drum bottom
Connected mode, be transformed into the mode being slidably connected with floating drum one or both sides, the benefit so transformed is；Before the water storage of reservoir area
The bottom surface that floating drum can be lain in generating set water intaking epistome is easy to floating drum being connected in series, then during water storage again
By in the guide groove of the guide rail welded on grid insertion floating drum side, the dirt that can greatly reduce during water storage in storehouse enters
Generating set, it is ensured that the normal work of generating set.In addition to preventing grid from being skidded off out of guide groove, it is welded with guide rail top
Limiting plate.In order to prevent grid from producing vibration in the presence of current, pressing plate is provided with floating drum, when grid is snapped down to minimum height
Guide rail can be fixed by bolt after degree.Most of installation can be completed before water storage by floating drum after above-mentioned improvement and buoyancy tank,
Most of dirt can be blocked in the water storage phase and does not enter diversion and power intake region, while engineering construction progress can be accelerated；Will be floating
Cylinder is separately designed as relatively small structure with grid, and convenience in transport is flexible for installation；Grid device quantity on single floating drum can root
Determined according to requirement of engineering, made in advance in factory, flexibility is strong；It is fixedly connected between grid and floating drum using bolt and pressing plate, side
Just dismounting and change.Engineering staff can stand completes grid installation on floating drum, without operation under water, improves working environment, drops
Low potential safety hazard；Bolt is arranged at more than water surface curve, facilitates engineering staff to operate；Grid track can directly use I-steel,
Also can designed, designed, flexible design.
