Abstract

The utility model relates to a live fish cultivating oxygen supply water device in pisciculture in people's daily life, particularly an adjustable vane wheel for a hydraulic turbine with an oxygen supply device. The utility model is composed of a vane wheel 1, a plurality of blades 2 and connecting bodies 11 thereof, and anchor peg sheets 3, and 4. A plurality of connecting bodies are extended on the wheel flange of the vane wheel. The blades are correspondingly penetrated and clamped on the connecting bodies by the anchor peg sheets. Blade mounting angles can be adjusted according to requirements to generate different pumpage angles and strike out different water blooms, air bubbles and water current forms so as to obtain various oxygen supply rates. The utility model can select optimal oxygen supply effect according to each kind of aquaculture to realize one machine with multiple functions, which can enhance the aquaculture rate and the survival rate.

Description

Adjustable vane wheel for hydraulic turbine with oxygen supply device

The oxygen supply of supporting fish that the utility model relates to pisciculture in the people life device of fetching water.

As everyone knows; aquaculture of a great variety; habit according to every kind of aquatic products; oxygen supply rate and current kenel that it is required are also had nothing in common with each other; the breed of eel class needs current more anxious, and the spray bubble then is minimum, and general fish need normal or bigger spray and bubble; contain the oxygen rate to improve in the water, supply with fish and obtain enough survival oxygen.Oxygen supply problem when culturing in order to solve, people have designed hydraulic turbine with oxygen supply device, present hydraulic turbine with oxygen supply device all is to adopt the motor impeller to fetch water, the oxygen supply so that evoke spray, because impeller all is unified specification, the angle that blade is installed on the impeller is certain, can not regulate, thereby the angle of pumping up water is all certain, and the spray bubble oxygen supply rate of playing is also identical.But in culture fishery, the habit of every kind of aquatic products is all different, so required amount of oxygen difference, if the amount of oxygen that hydraulic turbine with oxygen supply device provides is certain, often cause the drawback that oxygen is too much or lack, cause the survival rate of aquaculture to reduce, the oxygen part that influences aquaculture simultaneously absorbs, and causes damage.

The purpose of this utility model is the weak point at above hydraulic turbine with oxygen supply device impeller, intends providing a kind of impeller of adjustable hydraulic turbine with oxygen supply device, and it is made up of impeller, some blades and connector thereof, sheath bolt plate.On the rim faces of impeller, extend and be shaped on some connectors, adopt sheath bolt plate to wear fixing on the connector of impeller with some blades are corresponding respectively, blade can be selected to be installed on the corresponding through holes different on the connector as required, to reach the purpose that the blade angle degree can be regulated.And then make blade produce the different angles of pumping up water, and get different spray bubbles or current kenel, obtain the effect of different oxygen supply rates, select best oxygen supply effect, reach effect of one machine multiple purposes, improve the reproduction rate and the survival rate of aquatic products.

Realization of the present utility model is the impeller of a kind of adjustable hydraulic turbine with oxygen supply device of design, and it is made up of impeller, some blades, some connectors and sheath bolt plate.

On the wheel rim face, extend and be shaped on the connector that is connected mutually with each blade, be shaped on the through hole and the lower through-hole of plurality of fixed blade along the circumference of impeller tangent position in this connector upper and lower end face, these through holes correspond to the impeller center and form different arc angles respectively with the line of lower through-hole.

The upper and lower end face of blade be shaped on respectively with connector on arbitrary through hole and corresponding two holes of lower through-hole.

Adopt sheath bolt plate to wear fixing on the connector of impeller with each blade is corresponding respectively.

Below in conjunction with the accompanying drawing illustrated embodiment the utility model structure is elaborated:

113-through hole 114-lower through-hole

During enforcement, referring to Fig. 1 to Fig. 4, make each assembly of the utility model earlier, the impeller of adjustable hydraulic turbine with oxygen supply device is made up of impeller 1, some blades 2, some connectors 11,3,4 of some cover bolt formulas;

On impeller 1 rim faces, extend and be shaped on the connector 11 that is connected mutually with each blade 2, be shaped on the through hole 111,112,113 and the lower through-hole 114 of plurality of fixed blade 2 along impeller 1 tangent to periphery position in these connector 11 upper and lower end faces, this through hole 111,112,113 corresponds to impeller 1 center and forms different arc angles respectively with the line of lower through-hole 114.

The blade 2 of similar fan type, its upper and lower end face be shaped on respectively with connector 11 on lower through-hole 114 and arbitrary through hole 111 or 112,113 corresponding two

holes

21,22.

According to the selected angle of pumping up water, adopt sheath bolt plate 3,4 to wear fixing on the connector 11 of impeller 1 with each blade 2 is corresponding respectively.Change the setting angle of blade 2, can produce pump up water impeller 1 structure of angle of difference.Thereby impeller 1 can obtain different amount of oxygen and current kenel when fetching water oxygen supply.To every kind of aquaculture, can select its best oxygen supply state.

When required supply amount of oxygen is big, then blade 2 sockets are fixed in the position (referring to Fig. 5 to Fig. 8) that impeller 1A is ordered, at this moment blade 2 angle of pumping up water is relatively large; Otherwise, when required oxygen supply amount hour, then its blade 2 sockets are fixed in the position that impeller 1C is ordered, can make the angle of pumping up water less; For another example, as when seeking out the normal supply amount of oxygen, then blade 2 sockets are fixed in the position that 1B order, can reach blade 2 pump up water normally angle, oxygen supply amount and current kenel normally.

The utility model has the advantages that:

1. impeller of the present utility model, can being fixedly mounted with angle and can changing, arbitrarily regulate by means of blade, make it produce difference angle of pumping up water, the spray bubble of different amount of oxygen is provided, thereby, can select best oxygen-supplying amount and current kenel effect to each aquaculture, satisfy in the use the demand of all kinds of aquacultures, thereby improve breeding potential and the survival rate of aquatic products.

2. the impeller of adjustable hydraulic turbine with oxygen supply device, blade can have different setting angles. Angle can be regulated, the difference angle of pumping up water is provided, changed the in the past use state of a kind of blades installation angle, a kind of booster aerator of fetching water, this impeller is as long as on same body, change the setting angle of blade, just can reach a machine and can make multimachine and use, thereby reduce the cost of equipment cost, aquatic, economical and practical.
