Description

A kind of aerator

Technical field

The utility model belongs to the equipment of aquaculture industry, is specifically related to a kind of aerator.

Background technology

Aerator has in the aquaculture industry widely to be used; Its role is to effectively to solve the problem of the fish floating head that produces because of anoxic in the pond culture, also can help to eliminate pernicious gas, promote the water body convective exchange; Improve condition of water quality, improve fishpond activity and primary productivity.

The patent No. 201120052914.4, name are called in the Chinese patent file of " a kind of used for aquiculture solar energy economize on electricity oxygen-increasing device ", have disclosed a kind of aerator that utilizes solar recharging; This aerator comprises the accumulator of two groups of parallel connections, solar panel, generator; Power switcher, motor, decelerator and impeller; Through solar panel and with the motor generator coupled, in aerator operation, be charge in batteries.

Because solar panel costs an arm and a leg, above-mentioned oxygen-increasing device cost is corresponding higher, and this aerator building block is more, complex structure, and the reliability of operation and maintenance is not enough.In addition, after accumulator used a period of time, along with the minimizing of electrolyte, its capacitance can reduce, and influences the operate as normal of aerator, often needed the artificial accumulator that more renews.

Summary of the invention

To the deficiency of existing aerator power supply aspect, it is a kind of simple in structure, easy and simple to handle that the purpose of the utility model is to provide, the aerator that power and energy saving and cost are low.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of aerator comprises motor; Deceleration device and impeller; It is characterized in that: also comprise frequency converter, said frequency converter input inserts electrical network, and inverter output terminal links to each other with the input of motor; Motor output end is connected with the deceleration device input, and the deceleration device output is connected with impeller through rotating shaft.

Said deceleration device is decelerator or train of reduction gears.

Preferably, said frequency converter is the AC-DC frequency converter, and said motor is a direct current generator.

Compare the prior art scheme, the beneficial effect of the utility model is: reduce the use of parts such as solar panel, generator and block push button, not only greatly reduce cost, and strengthened the reliability of aerator; Adopt the combination of frequency converter and direct current generator, compared with using alternating current generator directly to insert the aerator power saving more of electrical network; Need not change accumulator, reduce manual operation.

Description of drawings

Fig. 1 is the system construction drawing of the utility model;

Fig. 2 is the schematic appearance of the utility model.

Among the figure: frequency converter 1, direct current generator 2, decelerator 3, impeller 4, shell 5, rotating shaft 6, pontoon 7.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Be illustrated in figure 1 as the system construction drawing of the utility model aerator, it comprises frequency converter 1, direct current generator 2, decelerator 3 and impeller 4.Said frequency converter 1 input inserts electrical network; Alternating current in the electrical network is become direct current; The output of frequency converter 1 links to each other with direct current generator 2 inputs, and direct current generator 2 output shafts are connected with decelerator 3 power shafts, and decelerator 3 output shafts are connected with impeller 4 through rotating shaft 6.

Fig. 2 is for adopting the product appearance sketch map of the utility model aerator; Arrange frequency converter 1 among the figure in the metal shell 5; Direct current generator 2 and decelerator 3; Rotating shaft 6 is passed metal shell 5 and is linked to each other with decelerator 3 in the housing, and at the two ends of hull outside mounted impeller 4 respectively, metal shell 5 is fixedly installed on two pontoons 7 together with internal components.

Particularly, the 220V single-phase alternating current that frequency converter 1 inserts input converts the output of 48V direct current into, and the rated voltage of direct current generator 2 is 48V, and rated power 500W, rotating speed are 600r/min, and the speed reducing ratio of decelerator is 3: 1.

Through test, adopt about the aerator operation power consumption once in three hours of such scheme.And present commercially available aerator, if use power 1500W, the motor of rotating speed 2800r/min moves power consumption in a hour and is approximately 1.5 degree.It is thus clear that, compare commercially available common aerator, the aerator of the utility model can power saving more than 2/3rds.

In addition, the aerator of the utility model is running into outage in emergency circumstances owing to adopt direct current generator, can use standby battery as power supply, inserts the input of direct current generator, and aerator can be kept normal operation.

At last, should be pointed out that above-mentioned embodiment only is the more representational example of the utility model.Obviously, the technical scheme 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 the protection domain of the utility model.
