Embodiment
It should be noted that directions such as counterclockwise in this example, clockwise, that left, right, front and rear are all are to face
Explanation is described on the basis of the direction that water comes.
As shown in Fig. 2, when water jet propulsion front propeller 2 rotates counterclockwise, so as to which preceding bevel gear 8 be driven to rotate counterclockwise,
Water jet propulsion rear screw shaft 3 rotates clockwise simultaneously, so as to which bevel gear 9 rotates clockwise after driving.In this way, forward and backward umbrella tooth
The reverse rotation of wheel imparts power to left and right gear simultaneously so that left bevel gear 10 rotates forward, and right bevel gear 11 turns round
It is dynamic, so as to provide driving force to clear fishing device.I.e. forward and backward bevel gear is input shaft, and left and right gear is output shaft.Before gear-box
Input shaft is connect with front propeller 2, and input shaft is connect with rear screw shaft 3 after gear-box；The left output shaft of gear-box and clear fishing device
Left drive shaft 4 connect, the right output shaft of gear-box is connect with the right transmission shaft 5 of clear fishing device, forms the power drive dress of this example
It puts.Tooth 6 is salvaged as shown in Figure 1, being equipped on left drive shaft 4 and right transmission shaft 5, every three are salvaged tooth as one group along left drive shaft
Or right transmission shaft circumference uniform distribution, every group of salvaging tooth form clover formula and drag for dress clearly along left drive shaft or right transmission shafts to being evenly distributed with
It puts.Clover formula is dragged for clearly device and is connect through stent with height adjustment device.Height adjustment device includes the tooth being fixed on stent
Item 16, rack are connect through transmission gear 18 with driving gear 17, and driving gear is connect with lifting rocking handle or motor.Positioned at clover
Formula drags for be equipped with rack on three stents at device both ends and gear-box clearly, is sequentially connected per toothed rack with transmission gear,
The transmission gear being sequentially connected with three stents is connected through a synchronizing shaft 19, one of transmission gear and driving gear
17 are sequentially connected, and when rotating driving gear, three transmission gears rotate the rack for driving and being located on three stents in water simultaneously
Cunning or downslide are synchronized on the drain grating 23 in 24 front of dam, the height of device can be dragged for clearly according to water level regulation clover formula, make three
It is concordant with up-stream face always that leaf grass formula drags for clearly device.
6 sharpness of salvaging tooth that clover formula is dragged for clearly on device transmission shaft can be according to the reality for determining power station upstream buoy rubbish
Situation is designed making, and when there is more much section of branch when floating materials, sharp salvaging tooth can be selected, in order to cut off long section drift
Whens floating refuse is mostly weeds leaf etc. when upstream, thicker salvaging tooth can be selected in floating rubbish；Clover formula is dragged on device clearly
Left and right transmission shaft and the gear-box 1 of centre are in same horizontal line and are supported by stent.Card slot is provided on rack or stent（Not
It draws）To be connect with trash rack 23, card slot can slide in the clamp rail of trash rack, the driving gear on height adjustment device
17 can be by chain transmission mode with indoor rocking handle or motor is controlled to connect, and the position of control room can be according to the practical need in scene
It arranges at an arbitrary position.
During specific entity, the clear structure design size for dragging for device need to be carried out according to the size of trash rack with reference to design, blocked
In the design of dirty grid, grizzly bar spacing is mostly important, and grizzly bar spacing should generally be controlled by the type and runner diameter D of the hydraulic turbine, axis
Flow water turbine D/20, Francis turbine D/30, impulse turbine are the 1/5 of nozzle diameter.In concrete engineering design,
Grizzly bar spacing should combine the property and quantity of dirt in flow, select maximum permissible value as far as possible.To big flow large-sized unit, such as axis
Flow water turbine, with due regard to based on " row ".To the small unit of small flow, such as Francis turbine then should be based on " blocking ", grid
Stripe pitch is not preferably greater than 100mm, but is not also preferably less than 50mm.The grizzly bar spacing of impulse turbine is generally also no less than
20mm.In this example, in order to which the clover formula for realizing clear fishing device is dragged for clearly, tooth can cleaning plug be stifled between deep enough grizzly bar, salvages the width of tooth
Degree is clear to drag for tine length 30cm between 50mm -100mm.
In actual installation in use, as shown in figure 3, Fig. 3 depicts the position of drain grating, the clover formula of this example drags for clearly dress
It puts and is mounted on drain grating.During specific installation, rack is installed to by card slot on trash rack first, the width of card slot will
Ensure there is the gap of 2mm after mounting, to ensure that rack can walk up and down in card slot, then secure the stand to rack
On, it is convenient that consideration is replaced, and the fixed form of stent is fixed using nut or pressing plate, then is dragged for respectively by stent by gear-box, clearly
Device is fixedly connected, it is contemplated that the dead weight of clear fishing device and the impact of upstream flow and rubbish, when mounted, stent uses three
Angle supporting way, to ensure the stability of support.One long side of triangle is vertically arranged, and is dragged on device clearly with clover formula
Left and right transmission shaft is connected with gear-box, and the angle at the top of triangle flap between the short bevel edge 21 of triangle is 45 °, triangle
Long bevel edge 22 is fixedly connected with rack.The long bevel edge of rack or triangle is equipped with sliding slot, and sliding slot is slidably connected with trash rack 23.
Test run on the preceding input shaft and rear input shaft of gear-box is attached separately to by stent supporting ＆ stablizing and then by former and later two propellers
Row carries out related fine tuning according to trial operation effect, ensures the smooth clear fishing of entire clear fishing device, finally by height adjustment device with
Rack connects, and driving gear is connect by linked transmission with control room, clear according to water level remote control clover formula to facilitate
Drag for the height of device.Manually control or Electronic control can be used in water level regulation, and so far, installation is complete for the invention.
