Description

Fish pond diving aerator

Technical field: the utility model relates to a kind of fish pond plant equipment, is meant a kind of fish pond diving aerator especially.

Background technology: diving aerator in fish pond is because of oxygenation in the water body under the ice face under the icing situation of fish pond in the winter time, thereby becomes the standard set in north cold area fish pond; At present, known fish pond diving aerator is axial-flow type diving aerator, it is divided into unidirectional and two-way two kinds, the axial liquid gas mixed flow that penetrates for the propeller-type impeller that prevents aerator during use impacts at the bottom of the pool, stir the mud at the bottom of the pool, submersible motor on it and sharf all are to tilt or horizontally disposed, so it has radially that volume is big, complex structure, weight is big, cost is high, jet direction is single and the defective of the submersible motor versatility difference on it.

The utility model content: the purpose of this utility model provide a kind of simple and compact for structure, cost is low, in light weight, jet direction many and the fish pond of submersible motor highly versatile diving aerator.

The purpose of this utility model is achieved in that a kind of fish pond diving aerator, comprises buoyancy tank, air inlet pipe, submersible motor and water pump, and wherein air inlet pipe vertically runs through by the air inlet pipe fixture and is arranged among the buoyancy tank; Lower end in air inlet pipe is serially connected with water pump, the centrifugal water pump that water pump is made up of water pump cover, centrifuge blade and centrifuge blade hollow shaft, on the axial plane of the centrifuge blade hollow shaft between adjacent two centrifuge blades, being scattered with the venthole that runs through centrifuge blade hollow shaft axial wall, on the radially-outer surface of water pump cover, be scattered with delivery port; The lower end activity of the upper end of centrifuge blade hollow shaft and air inlet pipe is cascaded, and the lower end of centrifuge blade hollow shaft is fixed together by the power take-off of centrifuge blade hollow shaft fixture and submersible motor; The water inlet of water pump is between the upper surface of the lower surface of water pump cover and submersible motor.

The air inlet pipe fixture is by being arranged on the buoyancy tank with the sleeve of air inlet pipe socket and being arranged on that air inlet pipe clamping screw on the sleeve forms.

Centrifuge blade hollow shaft fixture is made up of the centrifuge blade hollow shaft locking bolt that is arranged on centrifuge blade hollow shaft bottom.

Because air inlet pipe, water pump and submersible motor in the utility model all are to be connected in series in the mode that longitudinal axis overlaps, so radially volume of the present utility model is little, and simple in structure; Because of the delivery port of centrifugal water pump in the utility model is circumferentially to scatter to be arranged on the water pump cover, so its purpose that can only accomplish to all the winds comprehensive injection air water mixed flow with a submersible motor and water pump, its overall weight is light; The operating position and the state of the submersible motor on the operating position of the submersible motor in the utility model and state and the diving water pump are identical, so the submersible motor in the utility model can exchange with the submersible motor on the diving water pump and use, thereby can save the cost of a submersible motor.

Embodiment: the utility model will be further described below in conjunction with accompanying drawing, a kind of fish pond diving aerator, comprise buoyancy tank 9, air inlet pipe 6, submersible motor 14 and water pump, wherein air inlet pipe 6 vertically runs through by the air inlet pipe fixture and is arranged among the buoyancy tank 9, can adjust air inlet pipe 6 lower ends by the air inlet pipe fixture and stretch into the degree of depth in the water; As Fig. 2, shown in Figure 3, lower end in air inlet pipe 6 is serially connected with water pump, the centrifugal water pump that water pump is made up of water pump cover 10, centrifuge blade 3 and centrifuge blade hollow shaft 12, on the axial plane of the centrifuge blade hollow shaft 12 between adjacent two centrifuge blades 3, being scattered with the venthole 11 that runs through centrifuge blade hollow shaft 12 axial walls, on the radially-outer surface of water pump cover 10, be scattered with delivery port 12; The lower end activity of the upper end of centrifuge blade hollow shaft 12 and air inlet pipe 6 is cascaded, and is interconnected thereby make between the axis hole 16 of air inlet pipe 6, centrifuge blade hollow shaft 12 and the venthole 11, provides a passage for air enters water pump; The lower end of centrifuge blade hollow shaft 12 is fixed together by the power take-off 15 of centrifuge blade hollow shaft fixture and submersible motor 14; The water inlet 1 of water pump is between the upper surface of the lower surface of water pump cover 10 and submersible motor 14.

The air inlet pipe fixture can be by being arranged on the buoyancy tank 9 with the sleeve 7 of air inlet pipe 6 sockets and being arranged on that air inlet pipe clamping screw 8 on the sleeve 7 forms; Certainly it also can be other version with identical function, as cotter way structure, helicitic texture or snap ring structure etc.

Centrifuge blade hollow shaft fixture can be made up of the centrifuge blade hollow shaft locking bolt 13 that is arranged on centrifuge blade hollow shaft 12 bottoms; Certainly it also can be other version with identical function, as the spline structure etc.

For water pump pumps in the utility model the air water mixing ratio and the radius of spray of jet can be adjusted according to actual needs, on being positioned at pipe shaft on buoyancy tank 9 upper surfaces, air inlet pipe 6 can also be provided with an air intake valve 5.

As shown in Figure 4, for make by venthole 11 flow into air in the water pump covers 10 can be better with water pump cover 10 in water mix and obtain the centrifugal force of maximum, venthole 11 can be to be arranged on the centrifuge blade hollow shaft 12 with the tangent mode of the axis hole 16 of centrifuge blade hollow shaft 12.

If use the utility model at high and cold area, because of the temperature in high and cold area winter low excessively, in order to prevent in the winter time the utility model time spent not, the utility model can not be frozen in and can not normally use because of the water that blows back in the air inlet pipe 6 by venthole 11 and axis hole 16, on the pipe shaft between buoyancy tank 9 bottoms and the water pump cover 10, can also install a check valve in air inlet pipe 6 additional, thereby the time spent does not stop aqueous reflux to go into the top of air inlet pipe 6 at the utility model by it.

When the utility model is installed, at first the length of buoyancy tank 9 lower surfaces is exposed in the bottom of adjusting air inlet pipe 6 by the air inlet pipe fixture according to the degree of depth in fish pond, then according to definite which delivery port 2 that uses on the water pump cover 10 of the shape in fish pond, then only use two relative delivery ports 2 when being rectangle, and remaining delivery port 2 is blocked as the fish pond; When the fish pond is the square or circular whole delivery ports 2 of then use; At last the utility model is placed into the centre in fish pond, and the utility model is fixed both can by being fixedly installed on positioning rope system ring 4 usefulness buoyancy tank positioning ropes on the buoyancy tank 9.

When using the utility model, the power supply that only needs to connect submersible motor 14 makes centrifuge blade 3 high speed rotating, water in the water pump cover 10 is dished out by delivery port 2, make in the water pump cover 10 and produce vacuum, at this moment axis hole 16 and the venthole 11, water of air by air inlet pipe 6, centrifuge blade hollow shaft 12 is drawn among the water pump cover 10 by water inlet 1, and mix mutually, the mixed stream of mixed gas-liquid is dished out continuously from delivery port 2, thereby is reached for the purpose of water body oxygenation; Can control the content of gas in the mixed stream of gas-liquid by adjusting air intake valve 5, when the content of gas reduced, the radius of spray of the jet of delivery port 2 ejections increased in the utility model.
