Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done to describe in detail.
A kind of vertical axis type wind aeration machine of the present invention as shown in Figure 1, it comprises the perpendicular axis type blower fan, on the impeller shaft 2 of perpendicular axis type blower fan, be with arrangement for adjusting height 12, on described arrangement for adjusting height, be connected with at least three water repellent devices uniformly, each described water repellent device comprises the transverse axis 11 that the one end links to each other with arrangement for adjusting height, in on described transverse axis 11, passing through separately, outer side sleeve 10 is connected with a water wheel frame, water wheel axle 9 by the along continuous straight runs setting on described water wheel frame is connected with water wheels 8, the transverse axis that is positioned at each described outer side sleeve outside is provided with and can be close to the outside switchboard 14 that cooperates with outer side sleeve, on each transverse axis, be with spring 7, one side of described spring leans against on the described inboard sleeve pipe and its opposite side leans against on the inboard switchboard 6 that is arranged on the transverse axis, the bottom of described main shaft is connected with bearing, arranged outside at described at least three water repellent devices has the circular base of a plurality of formations 5, and the upper and lower sides of each described base 5 links to each other with bearing 13 with described main shaft 1 by union lever 4 respectively.The wind-force drives impeller is rotated in this device, makes main axis rotation, drives water repellent device and churns the surface; Main shaft links to each other with base 5 by union lever 4, and base 5 is bubbled through the water column, and the working water level of water repellent device is consistent with the water surface, and water repellent device can be according to wind-force size adjustment working range.
Described perpendicular axis type blower fan shown in Fig. 2-3 preferably is made up of three blades 3, each blade is an aerofoil profile, each blade interior is a cavity, each blade wing head is that trilateral and its wing tail outside have opening, opening both sides sidewall connects by support bar 15, links to each other by impeller shaft 2 between described blade 3 and the main shaft 1.This structure has the characteristics of resistance-type blower fan, and configuration design has the characteristics of lift-type blower fan again, the resistance when leg-of-mutton wing head design helps to reduce against the wind.Can certainly adopt existing other perpendicular axis type blower fan.
Preferred described transverse axis cross section and medial and lateral internal surface of sleeve pipe are regular hexagon.Prevent that water wheels from rotating around transverse axis, water wheels can be regulated working range automatically according to wind-force size within the specific limits, can realize best aeration in the aeration scope in conjunction with conditions such as water body oxygen consumption curve and mechanical dimension and wind speed.
Preferred described base is a floating drum, and the torus that constitutes at a plurality of floating drums is covered with purse seine.Can prevent that impurity enters the aeration scope in the sealing, easy to maintenance.
Described arrangement for adjusting height can be for being enclosed within the cuff on the main shaft, and described cuff is fixedly linked by web member and described main shaft.
Shown in Fig. 4-5, the turbine blade of preferred described water wheels in rotational direction has groove.Half there is not in the entry to make water wheels during work, water wheels when wheel shaft 9 rotates with groove in water body take out of, by marginal flow to the water wheels center.
This Unit Installation using method is as follows:
1. mounting seat 5 at first, according to the height of the position adjustments main shaft 1 of water wheels, half immerses the water surface, fixedly aerators when water wheels 8.
2. as Fig. 2, be example from left to right with wind direction, lower end blade wing afterbody is divided into cavity, and wind enters cavity and forms resistance, and upper end blade wing head is a trilateral, forms lift, and two kinds of power actings in conjunction produce counterclockwise blower fan and rotate around main shaft 1.
3. blower fan drive main shaft 1 produces and rotates counterclockwise, and water repellent device also begins to rotate counterclockwise, and when water wheels 8 moved forward, water wheels also began to rotate counterclockwise around wheel shaft 9, churn the surface.Because transverse axis 11 is a regular polygon with sleeve pipe 10 cross sections, makes water wheels vertical direction position basic fixed constant.The turbine blade profile as shown in Figure 5, the both sides inwall is a dead slot, is symmetrical structure, is applicable to different turning directions.The water body of water wheels groove inboard breaks away from the water surface with rotating, and converges to water wheel axle 9, flows back in the water again.Simultaneously, increase with rotating speed, water wheels are subjected to centrifugal force and spring 7 elastic force actings in conjunction, and beginning is moved laterally, up to stabilization of speed.When the abatement of wind, water wheels begin again to move to the inside, reduce the aeration scope.
