Abstract

A water aeration device for use in a fish breeding pond comprises an impeller (8) connected to a motor (4) and located in a duct 7 having water inlets (5). The duct has an outlet in a mixing chamber, the water flow sucking in air through an air intake pipe (10). The assembly is supported by floats (3). <IMAGE>

Description

WATER AERATION MACHINE This invention relates to a water aeration machine for fish breeding purposes and especially, to such a machine for fish breeding having a submerged motor and an air intake pipe of special construction so that the motor pumps the water to generate an instantaneous vacuum in a portion of the intake pipe such that air mixes with water flow to replenish oxygen in a fish breeding pond.
At present, conventional oxygen supply machines for fish breeding generally comprise a suction pipe extending out of the water surface, and a suction pump at the bottom of the suction pipe. Although such oxygen supply machines do oxygenate the water, the oxygenated water disperses in a very limited area, usually around the machine. Consequently the marine life gathers around the oxygen supply machine because the air supply is insufficient. One proposal for improvement uses a motor to drive a rotating blade in the water, and incorporates the known type of oxygen supply machine.
However, the stirring provided by such machines is limited to the local area of the rotating blades and air dispersion in the water is very limited. Besides, such combined constructions are quite complicated and it has proven difficult using this constructor to obtain a satisfactory response from users.
In view of the above-mentioned shortcomings, the applicant has carried out extensive studies to provide an improved oxygenation machine, based on his accumulated experiences in the manufacture of breeding equipment.
The invention provides a water aeration device comprising a submersible motor, an air intake pipe and at least one float for causing the device to float with the motor submerged and the air intake pipe extending into the air wherein the submersible motor is provided with an impeller for forcing water through a mixing chamber for air and water so as to suck air into the mixing chamber through the air intake pipe and to cause the air to mix with water in the mixing chamber and to be discharged from a water outlet.
The motor assembly preferably comprises means for connecting a hosepipe to the motor assembly, such that the device may be utilised for pumping water from a pond in which it is suspended.
In order that the invention may be better understood, a preferred embodiment will now be described, by way of example only, with reference to the accompanying diagrammatic drawings, in which: Figure 1 is an exploded view of a preferred oxygen supply device in accordance with the invention; Figure 2 shows the device of Figure 1 in the assembled condition; Figure 3 illustrates the operation of the device of Figure 2, and; Figures 4 and 5 illustrate alternative preferred embodiment of the invention; Figures 1, 2 and 3 illustrates the construction of a preferred oxygen supply device according to the invention for fish breeding purposes. The device comprises a motor assembly 1 air inlet assembly 2 and two floats 3. In the motor assembly 1, a water inlet chamber 6 with several water inlet holes 5 is provided at the front end of the motor 4.An impeller duct 7 is provided at the front end of the water inlet chamber 6, and an impeller 8, driven by the motor 4 is provided within the impeller duct 7, as shown in Figure 3. In use, water flows in via the inlet holes 5 of the water inlet chamber 6 towards the outlet of the impeller duct 7. At the front end of the impeller duct 7 a flange 9 is provided for connecting the motor assembly with air inlet assembly 2.
The air inlet assembly 2 comprises an air intake pipe 10, which extends out of the water surface and a coupler 11 as shown in Figure 3, the coupler 11 includes a large bore head portion 12 which tapers towards its outlet. The air intake pipe 10 is connected to head portion 12 and opens into the inner hollow portion of the head portion 12. The central portion of the water-inlet end of the head 12 comprises a connecting pipe 13 of which the outer diameter is slightly smaller than the bore of impeller duct 7 for facilitating insertion in the impeller duct 7. A flange 14 is also provided on the connecting pipe 13, such that, using a suitable sealing ring 15, flanges 9 and 14 may be connected together by bolts 16.The downstream end of the connecting pipe 13 is somewhat reduced in diameter, and extends beyond the connection point of air intake pipe 10 so as to minimise the formation of turbulent currents at the connection point, which would affect the effectiveness of the air supply.
Two fastening rings 17 are provided at the front and rear ends respectively of the motor assembly 1, and are fixed to the lower ends of two vertical adjusting rods 18. The upper ends of the vertical adjusting rods 18 are provided with several fixing holes 19 for adjusting the depth of the motor assembly. The fixing holes 19 at the upper ends of the vertical adjusting rods 18 serve to enable the fixing to a horizontal crosspiece 21 by means of brackets 20. The ends of crosspiece 21 are fixed by screws to the centre of horizontal support arms 22 of which the ends are fixed to the left and right floats 3 respectively by means of U-shaped fasteners so as to allow the oxygen supply device to sink and be suspended at a proper position in the breeding pond.The air intake pipe 10 extending out of the water surface is held at a suitable position on the crosspiece 21 by a fixing element 24 to reduce unnecessary vibration during operation of the device.
The operation of the device is illustrated in Figure 3. When the motor 4 starts, impeller 8 is caused to rotate and the pond water in the region of motor assembly 1 is sucked via the inlet holes 5 into the water inlet chamber 6. A current of water is pushed forward through impeller duct 7 to the coupler 11 of air intake assembly 2. The water flow is ejected from the discharge end of coupler 11, and causes a pressure differential such that air in air intake pipe 10 mixes with the water flow to replenish oxygen in the breeding water.
The motor assembly 1 may alternatively be erected vertically as shown in Figure 4 and arranged to suck pond water from a lower layer of the pond and spray it out upwardly so as to regulate water temperature in the upper and lower layers of the breeding pond. Moreover, the device may be provided with a connector for a flexible hose 25 for facilitating as illustrated in Figure 5 changing of the pond water. Thus, the illustrated device is multi-purposed.
At least in its preferred embodiments, the invention provides a new construction of the water aeration machine, suitable for fish breeding purposes which by virtue of the strong pumping action of the submersible motor and the incorporation of a specially constructed intake pipe, can pump water and simultaneously mix air into the water flow and circulate the aerated water widely to supply the oxygen required by marine life in the water. The submersible device described above can also be used to cause circulation of water between upper and lower layers.
Moreover, the device can also be used as a water pump when changing the water of the breeding pond.
