Abstract
A bubble generating device includes a shaft connected to a float and a plurality of frames connected to the bolt at their first ends. A porous device is connected to the respective mediate portions of the frames. A bolt extends through respective second ends of the frames and a weight is connected to the bolt. A pipe is connected to a fitting extending from the porous device so as to provide air into the porous device to generate bubbles. The bubble generating device can be maintained in water by adjusting the float and the weight.
Description
FIELD OF THE INVENTION
The present invention relates to a bubble generating device having a float and a weight to maintain the device in a desired position in the water.
BACKGROUND OF THE INVENTION
A conventional bubble generating device is shown in FIG.
1
and generally includes a two blade means
101
driven by a motor
100
. The bubble generating device is floated on water such as a pond, and the blade means
101
rotated to splash water in the air so that the water become many tiny water drops and fall into the water so as to increase the oxygen in the water. However, the bubble generating device cannot bear strong wind and the blades of the blade means
101
can only affect the water on the top surface of the water.
FIG. 2
shows another bubble generating device which has two blades
102
on a shaft
103
and the device can be sunk in water. The blades
102
stir the water in the casing
104
of the device to generate bubbles. This is a bulk device and requires a motor to drive the shaft and a gear reduction device to adjust the speed of the shaft. This is costly and the device cannot operate in deep water.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a bubble generating device and includes a shaft connected to a first float and a plurality of frames are connected to the shaft at there respective first ends. A porous device has a plurality of lugs extending therefrom and is connected to mediate portions of the frames by bolts. A fitting extends from the porous device and is connected to a pipe.
The primary object of the present invention is to provide a bubble generating device that can be operated in desired depth of water and the has a simple structure.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to
FIGS. 3
to
5
, the bubble generating device of the present invention comprises a shaft
1
connected to a first float
20
and a threaded section
12
is defined in a lower end of the shaft
1
. A plurality of frames
30
each have a first hole
31
defined in a first end thereof and a second hole
32
defined in a mediate portion of each frame
30
. The threaded section
12
extends through the float
20
and the three first holes
31
and engaged with a nut. A hole
11
is defined in a top of the shaft
1
so that a cable
13
tied with the hole
11
to hang the device.
A porous device
40
for generating bubbles is enclosed by the frames
30
and a pressing ring
50
located on a top surface of the porous device
40
. A plurality of lugs
51
extend from the pressing ring
50
and each lug
51
has a hole
510
. A plurality of first bolts extend through the respective second holes
32
in the frames
30
and the holes
510
in the lugs
51
to connect the porous device
40
to the frames
30
. A third hole
33
is defined through a second end of each frame
30
and a second bolt
34
extends through the third holes
33
of the frames
30
and is engaged with a first weight.
35
. A fitting
42
extends from the porous device
40
and is connected to a pipe
41
so that when air is introduced in the porous device
40
via the pipe
41
from a source of air, bubbles are generated by the porous device
40
.
As shown in
FIG. 6
, a second float
500
is connected to the cable extending from the shaft
1
and a second weight
54
is hung on the second float
500
by a cable
540
. The pipe
41
is attached to the cable
540
so as to reduce the possibility of affection of the bubble generating device by the un-positioned pipe
41
.
FIG. 7
shows a weight board
52
is located below the porous device
40
and posts
53
extend from the board
52
. The second float
500
is connected to the posts
53
so that the porous device
40
is located between the board
52
and the second float
500
. The second bolt
34
extends through the board
52
and the first weight
35
is hung below the board
52
. This structure allows the bubble generating device to be operated in a deep and wavy water. The lugs
51
can also be made integrally with the porous device
40
.
The device can be lowered into water because the weight
35
/
52
and the float
20
/
51
provides an upward force so that the device can be stayed at a desired depth in the water. The float
20
/
51
ensures the top surface of the porous device
40
always to face upward. By this way, the device can be operated in water and will not be affected by strong wind because only the cable is exposed out of the water.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.
