Description

Technical Field

[0001] The utility model relates to the technical field of submersible flow thrusters, in particular to a motor direct-connected submersible flow thruster. Background Art

[0002] Submersible flow thrusters are widely used in aeration tanks in the sewage treatment industry. They provide flow mixing and prevent sludge settling, making them essential, key equipment for sewage treatment. With increasing investment in sewage treatment and its widespread adoption worldwide, the market for this equipment is enormous, and manufacturers worldwide are striving to develop high-tech, highly competitive products to lead the global market.

[0003] Currently, most submersible current thrusters on the market use cylindrical gearbox reduction mechanisms, and the connection with the motor is not compact enough. Some even have couplings in the middle, resulting in multiple dynamic sealing links, low mechanical efficiency, and poor sealing effect. In addition, there is no reliable and comprehensive design for water leakage protection. Water ingress into the motor and reduction mechanism cannot be predicted in time and the heat dissipation function cannot be protected. This helps to extend the service life of the submersible current thruster and has great practical value.

[0004] For example, a motor-direct-connected cycloid star wheel submersible stream thruster disclosed in Chinese patent publication number CN101456631B combines the principles of planetary gears, small tooth difference, and cycloid pinwheel through a cycloid star wheel reduction mechanism. Bearings and cycloid star wheels are symmetrically installed on the outside of the eccentric sleeve in sequence. The three are tightly connected and, driven by the motor main shaft, form a planetary gear motion mechanism. Pinwheels are distributed around the cycloid star wheel, which is equivalent to the center wheel of the planetary gear. The outer edge of the cycloid star wheel is a cycloid tooth mechanism, which is equivalent to the gear teeth of the planetary gear with small tooth difference, reflecting the cycloid wheel principle. The cycloid teeth and pinwheels are in a symmetrical multi-tooth meshing rolling pair state, reflecting the working principle of the planetary gear with small tooth difference. This can make the structure delicate, reduce the volume, facilitate lifting and installation, and improve the transmission efficiency and increase the service life.

[0005] The existing technology has the following problems:

[0006] The above-mentioned submersible flow propeller is not very closed, so there is a lack of corresponding diversion devices when performing flow stirring in the aeration tank. The liquid can easily escape into the drive cavity and contact the drive component, causing a short circuit in the drive element, and the liquid will remain inside the flow propeller for a long time. Utility Model Content

[0010] The guide device includes a guide unit and a drive unit, which are connected to each other, wherein the guide unit includes a guide drive shaft, a mounting connector is provided in the middle of the guide drive shaft, and a guide blade is provided on the outside of the mounting connector, and the guide blade is located on one side of a power coupling, and the other end of the power coupling is connected to a drive worm.

[0016] In the present invention, the rotation of the drive worm causes the second transmission member to rotate, which in turn causes the drive worm to begin rotating. At this point, the drive output shaft 1 obtains power. Because the drive worm is in transmission connection with the first transmission member, as soon as the transmission member begins rotating, the drive output shaft 2, which is fixedly connected to the first transmission member, obtains power. A drive mold is provided on the fixed mounting plate, and the drive unit is mounted within the drive mold.
