Impeller-type aerator for aquaculture

Abstract

The invention provides an impeller-type aerator for aquaculture. The impeller-type aerator includes a motor controller protection hood, a support rod device, a brushless direct-current motor, supportrods, buoys and an impeller; the support rod device is mounted at the upper end of the brushless direct-current motor, the motor controller protection hood is mounted at the upper end of the support rod device, the support rods are assembled on the support rod device, the buoys are arranged at the outer ends of the support rods, and the impeller is assembled under the brushless direct-current motor. According to the impeller-type aerator for the aquaculture, the motor controller protection hood is used for waterproof protection, the support rod device is subjected to waterproof protection, andthe design improves the overall stability of the impeller-type aerator; the impeller-type aerator is easy to operate, convenient to mount and good in stability, the function of overload protection isachieved, the magnitude of currents is convenient to detect.

Description

technical field [0001] The invention relates to an impeller type aerator for aquaculture, which belongs to the technical field of aquaculture. Background technique [0002] Pond aquaculture, that is, the freshwater fishery industry, is an industry that can improve the efficiency of human food energy intake. The development of pond aquaculture has developed due to the development of modern human civilization and has a step-by-step technological innovation and change. Throughout the history of pond culture, the unoptimistic phenomenon of long-term unit output and total output has led to the emergence of various types of aeration equipment. [0003] In the prior art, the main structure of the impeller aerators on the market is composed of brushless DC motors, gearboxes, impellers, struts, buoys, etc. Most of the brushless DC motors of impeller aerators on the market are induction motors At present, some of them have been changed to DC brushless inner rotor motors, induction mo...

Problems solved by technology

[0003] In the prior art, the main structure of the impeller aerators on the market is composed of brushless DC motors, gearboxes, impellers, struts, buoys, etc. Most of the brushless DC motors of impeller aerators on the market are induction motors At present, some of them have been changed to DC brushless inner rotor motors, induction motors, motor drive circuits, complex cost, low efficiency and power density, and unsatisfactory oxygenation effect. Compared with induction motors, DC brushless inner rotor motors have relatively simple motor control , the efficiency and power density of the motor have been improved. The existing aerators in the market are equipped with a deceleration mechanism that requires refueling and regular maintenance. The existence of the deceleration mechanism reduces the overall stability of the aerator equipment, so a kind of Impeller type aerator to solve the above problems
