Description
Technical field
This utility model relates to Hydraulic and Hydro-Power Engineering, especially relates 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; excess dirt accumulation also makes trash rack deformation even collapse; causing power station, pumping plant to be shut down, the safety in production having a strong impact on engineering runs.At present intake of hydropower station, the measure of removing contamination of pumping plant intake position trash rack is mainly taked to carry grid and is removed contamination, presses dirty tooth harrow to remove contamination and trash grabs the modes such as dirt, and 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 dirts such as the pasture and water, branch and the rattans that are wrapped on trash rack grizzly bar, in addition to shutdown carries grid and manually removes, still without other effective measures of removing contamination.
Summary of the invention
This utility model purpose is to provide a kind of dirt cutting mill under water being suitable to Hydraulic and Hydro-Power Engineering.
For achieving the above object, this utility model takes following technical proposals:
The dirt cutting mill under water being suitable to Hydraulic and Hydro-Power Engineering described in the utility model, 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, fixed cover it is spaced equipped with multiple harrowing wheels on line shaft, 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 on the arranged on left and right sides column of " door " sub-shape framework and 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 with described submersible machine by drive mechanism.
This utility model advantage is to realize directly cutting and grinding dirt the most under water, the problem both having solved dirt blocking runner, eliminates again the salvaging of dirt, the problem such as transports, disposes and bury, reduces 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 described in the utility model, 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, fixed cover it is spaced equipped with multiple harrowing wheels 5 on line shaft 4, 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 difference of the present embodiment and embodiment 1 is, 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 is with the difference of embodiment 1, 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 all connected with line shaft 4 by drive mechanism 11；The present embodiment is primarily adapted for use in the trash rack dirt cutting and grinding under water of longspan structure.
Utility model works principle is summarized as follows:
When needing the dirt cleaning that trash rack 7 front is piled up, after this utility model 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 extruding dirt, 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, can be one saw blade of grid 6 or the multiple saw blade of grid 6.
Saw blade 6 and harrowing wheel 5 are sequentially arranged according to trash rack 7 interval of grid strip, pasture and water that saw blade 6 cutting and grinding in the middle part of grizzly bar are wrapped on grizzly bar, branch.Owing to before grid, dirt suffers from water impact extruding, dirt after cutting may be still squeezed state before grid, the pasture and water of cutting and crushing, branch before saw blade 6 side and grid are loosened and are transferred to upstream by the harrowing wheel 5 using 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 ensureing to cut the pasture and water before being wrapped in grizzly bar, branch and rattan etc., the saw blade 6 that simultaneously turn avoid high speed rotating cuts to grizzly bar and grizzly bar gripper shoe, the safety of protection trash rack 7.Also limit cutting machine in stream downstream and the displacement of Transverse to the flow direction, it is ensured that saw blade 6 and the harrowing wheel 5 safety to grizzly bar simultaneously.
