Abstract

The utility model discloses a double-wheel rotary oxygen increase machine which belongs to oxygen increase machinery for a fish pond. Two impellers (9) are arranged on the two sides of an electric machine (1), and the utility model both can autorotate and can revolute surrounding the shaft of a center electric machine. Water lift range and water mixing range are greater, and the utility model is equivalent to two sets of oxygen increase machines which can move. The working condition is shapely, the double-wheel rotary oxygen increase machine can stop revoluting when fish float the head, the fish can be fast rescued, and the oxygen increase effect is good.

Description

Double wheel rotary aerator

The utility model belongs to oxygen-enriching machine in fish pond tool equipment.

Vane type, Waterwheel-type, water jet, water burst formula, fan blower formula, jetting type etc. are arranged in prior art.The aerator of these patterns plays a role in the oxygenation process of fish pond, and its advantage is respectively arranged, and its shortcoming is also respectively arranged.With regard to oxygenation effect, with present paddle aerator the best, the paddle aerator pattern drives the inverted umbrella shaped impeller rotation and stirs water by belt, gear, worm gear reducer (or without slowing down) for the central upper motor, motor and impeller etc. are supported in the three island type buoyancy aid by three bars and bubble through the water column, the impeller fixation is certain point in water, stirs the water scope and does not change.

The purpose of this utility model is the improvement to paddle aerator, improves its oxygenation effect and energy power and energy saving to the fish pond.

Design concept scheme of the present utility model: with a motor is that two impellers are arranged in middle mind-set both sides under water, be equivalent to two paddle aerators in work, and because these two impeller symmetries depart from the motor shaft center, the moment of torsion that produces under the effect of water counter-force can make impeller center on the revolution of motor shaft center, it is that big garden ring-type, two impellers are arranged in weight and symmetrical in shape that water lift stirs the water scope, impeller revolution motion state is attractive in appearance, motor places center fixation under water, and electric wire feeds and do not use brushgear.Motor shaft can be given impeller with belt pulley or gear shaft transmitted power, raise the nose above water to breathe to rescue the working condition of fish danger for adapting to fish body anoxic, do not make the fish body of the impeller injury floating head of revolution motion, be provided with the reverse stopper of ratchet in this conception plans, as long as the operating power two-direction switch makes the motor reverse rotation, impeller is and then counter-rotating also, revolution motion will stop, and oxygenation is at this moment rescued fish and effectively is microscler broadband shape in the district.

Obviously, the utility model is compared with other form aerators, has simple in structurely, and duty is attractive in appearance, and oxygenation effect is good, the advantage of power and energy saving.

Below in conjunction with accompanying drawing structure of the present utility model and operation principle are described further:

Accompanying drawing 1 is the front view of the rotary aerator of a kind of two-wheel of the present utility model.Fig. 2 is the vertical view of the rotary aerator of the utility model two-wheel.Accompanying drawing 3 is figure that A-A analyses and observe at the place amplification among Fig. 1.

Referring to Fig. 1 and Fig. 2, rope (19) links motor case (2) and is fixed in fish pond or the pond, and electric wire (20) is from feeding under water, and floating drum (10) plays the effect of additional balance complete machine.In the middle of the motor case (2) is motor (1), and motor (1) adopts common electric machine to add the watertight tube or adopts submersible motor.The motor case is the watertight tube, the double as buoyancy aid.Motor shaft passes through yielding coupling (6) drive bevel gear (7) again by bevel gear (4) drive bevel gear (5), thus drive bevel gear (8) impeller (9) rotation, and the both sides impeller is in like manner.

Oppositely the cutaway view Amplified image of ratchet stop (3) is seen accompanying drawing 3.Referring to Fig. 3 and Fig. 1, hollow cylinder (17) is fixed on the motor case (2), two place's breach are arranged on the hollow cylinder (17), live pin and ratchet (15) are housed, spring (16) makes and is engaged in ratchet (14) in the ratchet (15), and ratchet (14) and reduction-gear casing (11), (13) and transmission arm (12) fuse.When the clockwise time rotational of impeller (9), drive reduction-gear casing (13), transmission arm (12), reduction-gear casing (11) and ratchet (14) again together around motor shaft (18) revolution counterclockwise.

Revolution stops as need, only need the operating power two-direction switch can make the motor counter-rotating, the counter-clockwise rotation of impeller (9), ratchet (14) is clockwise rotated, owing to the ratchet (15) on the hollow cylinder (17) that is fixed in motor case (2) props up transmission arm (12), revolution promptly can stop impeller (9) rotation in the same old way.

Claims

1, a kind of paddle aerator that is used for the fish pond, comprise the transmission mechanism between motor case (2), motor (1), impeller (9) and motor and the impeller that is fixed in the water of fish pond, it is characterized in that described impeller (1) has two, driven by described transmission mechanism by a shared motor (1), two impellers (1) symmetry departs from described motor (1) axle center, fixedly the case shell (11) of impeller (9) is by linking mutually with ratchet and pawl arrangement (14,15) between transmission arm (12) and the described motor case.

2, paddle aerator according to claim 1, it is characterized in that described transmission mechanism is that the axle of described motor (1) is by bevel gear (4) drive bevel gear (5), pass through yielding coupling (6) drive bevel gear (7) again, thus drive bevel gear (8) impeller (9).
