Abstract

The invention discloses a pond aerator without an external power source and aims to solve the problems that existing aeration devices are higher in cost and lower in service life and need continuous electric energy consumption. The device comprises a floating ring, a bogie, an end cam, a sliding rod, a rotating disc, a main rotating shaft, an air sealing block, aeration blades, an air following plate and an air stopping block. The bogie comprises a rotating ring and a support frame; the rotating ring and the floating ring constitute a revolute pair; the main rotating shaft is supported on therotating ring; the air following plate is fixed on the support frame; the rotating disc comprises a blade pillar and a sliding rod disc; n aeration blades are arranged on the blade pillar in a hollowmanner; multiple aeration holes are formed in the aeration blades; the work contour of the end cam comprises a push-out section, a transition section and a retraction section; n sliding rod through grooves circumferentially and uniformly distributed on the sliding rod disc are formed in the sliding rod disc. The device can realize continuous aeration of pond water under drive of wind instead of external electric power.

Description

technical field

[0001] The invention belongs to the technical field of aeration devices, and in particular relates to a pond aeration device without an external power source. Background technique

[0002] The level of dissolved oxygen in the pond will have a huge impact on the growth of ornamental fish and ornamental plants in the pond. The existing aeration device generally increases the dissolved oxygen amount by blowing air continuously at the bottom of the water body, which can obviously promote the breeding effect of the water body. However, the existing aeration device has the problems of high cost, continuous consumption of electric energy and low service life. In addition, due to the small contact area of ​​the water body, most of the air injected into the bottom of the water by the existing aeration device floats up and overflows, causing serious waste. Only some ornamental fish need to be cultured in ponds in cities, and such a large amount of dissolved oxygen is...

Examples

Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] Such as figure 1 , 2 As shown in and 3, a pond aeration device without external power source, floating ring 1, bogie 2, end cam 3, sliding rod 4, rotating disc 5, main rotating shaft 6, air sealing block 7, aeration blade 8 , chasing wind plate 9, auxiliary turntable 10 and choke block 11. The floating ring 1 includes an upper floating ring and a lower floating ring. The material of the upper floating ring and the lower floating ring is plastic, and they are coaxially fixed together. The opposite sides of the upper floating ring and the lower floating ring are provided with annular grooves.

[0033] Such as figure 1 , 2 As shown in and 3, the bogie 2 includes a rotating ring 2-1 and a support frame 2-2. The rotating ring 2-1 is arranged between the annular grooves of the upper floating ring and the lower floating ring, and constitutes a rotating pair with the ...
