Description
Technical field
The present invention relates to Hydraulic and Hydro-Power Engineering, especially relate to be suitable to the dirt cutting mill under water of Hydraulic and Hydro-Power Engineering.
Background technology
A large amount of dirt accumulation is often had before the trash rack that the positions such as intake of hydropower station in Hydraulic and Hydro-Power Engineering, water-carriage system, pumping plant intake are installed; runner flow is caused to reduce; excessive dirt accumulation also makes trash rack deformation even collapse; causing that power station, pumping plant are shut down, the safety in production having a strong impact on engineering runs.Current intake of hydropower station, pumping plant intake position trash rack measure of removing contamination mainly take to carry grid and remove contamination, press dirty tooth harrow to remove contamination and trash grabs the modes such as dirt, the dirt of salvaging also needs to carry out transporting, dispose and burying.Above-mentioned measure alleviates dirt to a certain extent and blocks the problem of runner, but for being wrapped in the dirts such as pasture and water on trash rack grizzly bar, branch and rattan, except carrying grid except shutdown and manually removing, still without other effective measures of removing contamination.
Summary of the invention
Present invention aim at providing a kind of dirt cutting mill under water being suitable to Hydraulic and Hydro-Power Engineering.
For achieving the above object, the present invention takes following technical proposals:
The dirt cutting mill under water being suitable to Hydraulic and Hydro-Power Engineering of the present invention, including " door " sub-shape framework, is arranged on the hanger on described " door " sub-shape cruciform bracing, is provided with cutting and grinding mechanism on " door " sub-shape framework；The line shaft that described cutting and grinding mechanism is driven by submersible machine, described line shaft is horizontally set on " door " sub-shape framework by bearing body, on line shaft, interval fixed cover is equipped with multiple harrowing wheels, on line shaft between adjacent harrowing wheel, fixed cover is equipped with saw blade, and the diameter of described saw blade is more than the diameter of described harrowing wheel；It is positioned at and the arranged on left and right sides column of " door " sub-shape framework is respectively fixed with the guider being slidably matched with trash rack upper rail.
Being positioned in the middle part of the crossbeam of " door " sub-shape framework and be fixed with middle standing pillar vertically downward, described cutting and grinding mechanism is two sets, is separately positioned between described middle standing pillar and described arranged on left and right sides column.
Described line shaft is in transmission connection by drive mechanism and described submersible machine.
The invention has the advantages that realization directly cutting and grinding dirt, the problem both having solved dirt blocking runner under water, eliminate again the salvaging of dirt, transport, dispose and the problem such as bury, reduce engineering operation cost；Reach removing contamination rapidly and efficiently simultaneously, be that Hydraulic and Hydro-Power Engineering is removed contamination the important breakthrough of measure.

Detailed description of the invention
Embodiment 1:
As shown in Fig. 1,2,5,6,7, the dirt cutting mill under water being suitable to Hydraulic and Hydro-Power Engineering of the present invention, including " door " sub-shape framework 1, it is arranged on the hanger 2 on " door " sub-shape framework 1 crossbeam, " door " sub-shape framework 1 is provided with cutting and grinding mechanism；The line shaft 4 that cutting and grinding mechanism is driven by submersible machine 3 direct connection, line shaft 4 is horizontally set between " door " sub-shape framework arranged on left and right sides column by bearing body, on line shaft 4, interval fixed cover is equipped with multiple harrowing wheels 5, on line shaft 4 between adjacent harrowing wheel 5, fixed cover is equipped with saw blade 6, and the diameter of saw blade 6 is more than the diameter of harrowing wheel 5；It is positioned on the arranged on left and right sides column of " door " sub-shape framework 1 and is respectively fixed with the guider being slidably matched with the guide rail 8 on trash rack 7；As it is shown in fig. 7, the slide block 10 that guider is offered chute 9.1,9.2 by arranged on left and right sides is constituted.
Embodiment 2:
As it is shown on figure 3, the present embodiment and embodiment 1 are distinctive in that, the submersible machine 3 of cutting and grinding mechanism is connected with line shaft 4 by chain wheel driving mechanism 11；This mainly considers that big-and-middle-sized cutting mill is affected by the power of submersible machine 3 and volume and during unsuitable direct connection, by drive mechanism 11, the moment of torsion of submersible machine 3 reached line shaft 4.Drive mechanism can be the various ways such as gear, sprocket wheel, pulley drive.
Embodiment 3:
As shown in Figure 4, the present embodiment and embodiment 1 are distinctive in that, it is positioned in the middle part of the crossbeam of " door " sub-shape framework 1 and is fixed with middle standing pillar 12 vertically downward, it is respectively provided with a set of cutting and grinding mechanism between the arranged on left and right sides column of middle standing pillar 12 and " door " sub-shape framework 1, Mei Tao cutting and grinding mechanism is identical with the cutting and grinding mechanism of embodiment 2, and the submersible machine 3 of Ji Meitao cutting and grinding mechanism is connected with line shaft 4 each through drive mechanism 11；The present embodiment is primarily adapted for use in the trash rack dirt cutting and grinding under water of longspan structure.
Operation principle of the present invention is summarized as follows:
When needing the dirt cleaning that trash rack 7 front is piled up, after the present invention is sling by erecting equipment by the hanger 2 on " door " sub-shape framework 1 crossbeam, it is slidably matched by the guide rail 8 on the guider on " door " sub-shape framework 1 arranged on left and right sides column and trash rack 7 and drops to fixed range before trash rack 7 grid under water, the dirt before trash rack 7 grid can be cut from top to bottom.In work process, first dirt being extruded, then submersible machine 3 drives multiple saw blade 6 that dirt is carried out cutting and grinding；Dirt after pulverizing, after harrowing wheel 5 loosens, utilizes the suction of current, dirt fragment to pass through after trash rack 7 enters unit stator or water pump blade and pours downstream.
The number of saw blade 6 can require to determine according to dirt silting situation, trash rack 7 size, the hydraulic turbine or water pump with spacing, it is possible to is one saw blade of grid 6 or the multiple saw blade 6 of grid.
Saw blade 6 and harrowing wheel 5 are sequentially arranged according to trash rack 7 interval of grid strip, and saw blade 6 cutting and grinding in the middle part of grizzly bar are wrapped in the pasture and water on grizzly bar, branch.Owing to before grid, dirt suffers from water impact extruding, dirt after cutting is likely to still for squeezed state before grid, the pasture and water of cutting and crushing, branch before other for saw blade 6 and grid are loosened and are transferred to upstream by the harrowing wheel 5 adopting coaxial rotating, cutting machine moves to prevent the dirt after cutting from stopping, working continuously for cutting machine continuation decline creates conditions.The pasture and water shredded and loosen, branch suck unit stator under flow action subsequently or water pump blade pours downstream.
Guider primarily serves the purpose of specification cutting machine working range; guarantee saw blade 6 and the harrowing wheel 5 position before grid; both ensure to cut the pasture and water before being wrapped in grizzly bar, branch and rattan etc., turn avoid the saw blade 6 of high speed rotating simultaneously and cut to grizzly bar and grizzly bar gripper shoe, the safety of protection trash rack 7.Also limit the cutting machine displacement at stream and Transverse to the flow direction downstream, it is ensured that saw blade 6 and the harrowing wheel 5 safety to grizzly bar simultaneously.
