Description
Technical field
The present invention relates to a kind of fish pond oxygen increasing equipment, specifically is a kind of slewing gear for mobile automatic aerator.
Background technology
Aerator is the indispensable machinery of fish pond high and stable yields, is used widely in fishery cultivating production.We are generally vane type by seen aerator, and the overwhelming majority is that fixed point work is promptly fixed.Because the water area of aerator load is limited, so the oxygenation effect of this aerator weakens with the increase of losing oxygen district and aerator distance.Especially, general start back was less than 1 hour, and this central area, aerator place just reaches the oxygen saturation state, and oxygen can only rely on the mutual interchange of frontier water to spread, and therefore, has reduced the result of use of aerator.Change this situation, just must make aerator directly act on oxygen district thanks to, make aerator become fixed and enlarge the direct zone of action of facility, further bring into play its effect, improve its service efficiency into portable.
And the greatest problem of mobile automatic aerator is the cable winding, and at present, the settling mode of prior art has two kinds, and first boat form utilizes diesel engine to be used as power, and does not have this root of cable " tail ", but needs the people to operate control, and noise is too big, so, be difficult to promote; It two is similar dc motors, utilizes carbon brush, slip ring effect, avoids the cable rotation, and aerator utilizes the counter-force idol of water body, can rotate around fixing point, but since factor such as price is higher, poor stability and reliability are not strong do not promote yet and open.
Summary of the invention
The technical problem to be solved in the present invention is, the slewing gear for mobile automatic aerator that provide a kind of and do not need that the people operates that control, noise are little, reasonable price, safety reaches good reliability well.
Technical solution of the present invention is, a kind of slewing gear for mobile automatic aerator with following structure is provided, and it comprises the cable of impeller automatic aerator, floating drum and power supply; Described floating drum specific bit floating drum and float lever thereof and at least three aerator floating drum I of fixedlying connected and aerator float lever I and aerator floating drum II and aerator float lever II and aerator floating drum III and aerator float lever III thereof with impeller automatic aerator; It also comprises the connecting rod I that connects location float lever and aerator float lever I, be located at cam mechanism I and the cam mechanism II that is located on the aerator float lever I on the float lever of location, can stir to stop or to pass through cross bar I and the cross bar II of aerator float lever II by cam mechanism I and cam mechanism II; The carriage that has current supply cable, cross bar I and cross bar II to slide on the connecting rod I thereon; The junction of location float lever and aerator float lever I and connecting rod I all makes its relatively turnable bearing; Cable is connected with the electromotor of impeller automatic aerator with aerator float lever I through location float lever, carriage; The level height on described aerator float lever III top is lower than the level height of cross bar I and cross bar II.
After adopting above structure, the present invention compares with the mobile automatic aerator of prior art, has the following advantages:
The present invention adopts a kind of brand-new slewing gear for mobile automatic aerator, and impeller automatic aerator alternately rotates around aerator float lever I and location float lever axis, cable circulation degree of tightness promptly by forward take up 180 ° with oppositely take up-180 °, avoided the cable winding.It does not need manual operation control, and noiseless, and price is low, and security performance is good, and functional reliability is strong.
As improvement, resist stubbornly when avoiding cross bar I to contact with cross bar II, described cross bar II can be made up of cross-bar body and the telescopic head away from the other end of cam mechanism II that is installed in cross-bar body, can set up a rubber-like telescopic head.
As further improvement, there is an overcoat aerator float lever II upper end for pin is that pin is external, a plurality of balls is arranged, the frictional force when sliding on pin with the minimizing cross bar on the mating surface of pin body and overcoat.
