Description
Technical field
The utility model relates to a kind of water wheel type ventilator.
Background technology
Water wheel type ventilator is comparatively common a kind of in the present aquaculture oxygen increasing equipment, its simplicity of design, light, and its biggest advantage is power saving.
Its oxygenation principle is different with vane type and Waterwheel-type, and unique flower shape screw impeller cooperates annular floating drum, can make the upwards eruption of water of output, the water body that causes certain zone is the boiling shape, thus improve water in the eruption process with the contacting of air, thereby improve the dissolved oxygen amount of water body.
Secondly, water can not generate heat motor and reductor upwards directly passing through motor and reductor in the eruption under the situation of continuous operation, has got rid of the common fault that motor burns out because of long-time running heating.
And can under the ELV of 310V-350V, run well.
The motor of this product and reducing gear are totally-enclosed waterproofing design, with respect to the actual saving of paddle aerator power consumption about 58.3%.
What but this aerator adopted is alternating current generator, and is subjected to due to the condition, and the user often can only adopt civilian electricity to drive, and this type of motor needs often to change consumable accessorys such as carbon brush, electric capacity, causes the rising of using inconvenience and cost; Simultaneously, there is the not high shortcoming of energy utilization rate in alternating current generator.
Summary of the invention
At the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, power and energy saving, DC frequency-changing water wheel type ventilator easy and simple to handle.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of DC frequency-changing water wheel type ventilator, comprise motor, buoyancy aid, bracing frame, gear-box and impeller, the bracing frame that is used for support motor and gear-box is installed on the annular buoyancy aid, connect gear-box under the motor, gear-box connects impeller down, it is characterized in that described motor is a direct current generator, this aerator is provided with a DC frequency changer that is used to control the direct current generator running, and this DC frequency changer comprises
Be used to provide the Power Entry Module that drives electric energy,
The driving electric energy that is used for that Power Entry Module is provided is converted into galvanic frequency conversion direct current three phase controllers,
Above-mentioned parts are the Electricity Federation successively.
In described Power Entry Module is 220v or the civilian AC power of 110v.
Described Power Entry Module is a solar panel.
Scheme compared to existing technology, the beneficial effects of the utility model are: adopt the combination of frequency converter and direct current generator, compared with using alternating current generator directly to insert electrical network energy saving more, energy-conservation reaching more than 60%; Adopt permanent-magnet brushless DC electric machine simultaneously, do not need often to change consumable accessorys such as brush, have bigger starting torque, have good speed adjusting performance with respect to alternating current generator; Compatible various power supply input patterns can adapt to the environment for use of various complexity.
Description of drawings
Fig. 1 is the utility model aerator structural representation.
Fig. 2 is the system architecture diagram of the utility model DC frequency changer.
Wherein: 1, buoyancy aid, 2, bracing frame, 3, motor, 4, gear-box, 5, impeller, 6, DC frequency changer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Aerator is by buoyancy aid 1 as shown in Figure 1, bracing frame 2, and direct current generator 3, gear-box 4, impeller 5 and DC frequency changer are formed, and the DC frequency changer 6 that direct current generator 3 sets can be connected or is provided with separately in addition with direct current generator 3 is airtight, satisfies different user demands.
Be illustrated in figure 2 as the utility model DC frequency changer system architecture diagram, comprise the Power Entry Module of Electricity Federation successively, frequency conversion direct current three phase controllers.
Power input part spare form can be common 220v or the civilian AC power of 110v, or is solar panel, or is accumulator etc.
When power input part spare was accumulator, described frequency conversion dc controller can be remote control control.
Frequency conversion direct current three phase controllers is converted into the use of direct current supply direct current generator with the electric energy of Power Entry Module input.This controller can adapt to different electric energy inputs, and when the input electric energy was the civilian alternating current of 220v or 110v, this controller was translated into direct current; When the input electric energy be solar panel produce direct current the time, this controller only plays the effect of rectification or frequency conversion, the direct current of power generation plate is transformed to meet the rated voltage that direct current generator uses.
At last, should be pointed out that above-mentioned embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
