Problems solved by technology
Most of the original water wheel aerators use air-cooled motors, and the motors are equipped with waterproof covers. In order to cool the motors, the waterproof covers are higher than the fan blades of the motors. The motor can be cooled by air, but this cooling wind is inside the cover. Circulation, in order to make the steam evaporated on the water surface have a rising channel, some waterproof covers have air outlet holes, which can discharge the water vapor in the cover when the aerator is not working, and cannot cool down the motor when it is working Therefore, the heat dissipation condition of the existing water wheel aerator is not good, and the motor cannot work at full load, especially the bearing in the upper end cover of the motor is relatively easy to be damaged

Embodiment Construction
[0026] In the figure: 1-waterproof cover; 2-air inlet; 3-fan; 4-motor; 5-reduction box; 6-base; 11-cover; 12-impeller; 13-floating body; 14-surrounding ring;
[0027] The present invention will be further described below with specific embodiment, see Figure 1-9 :
[0028] A waterwheel type aerator is mainly composed of a motor 4, a reduction box 5, an impeller 12, a floating body 13, a bracket, and a waterproof cover 1. There is an air inlet 2 on the waterproof cover 1, and a cover 11 is arranged on the air inlet 2; 2 There may be a surrounding ring 14, the direction of the surrounding ring 14 facing the water has protruding rafters 15, and there are multiple water retaining ribs 16 on both sides of the outer side of the surrounding ring 14, the purpose of which is to prevent water splashes between the cover 11 and the waterproof cover 1 Enter, if waterproof cover and cover are made into one, surrounding ring 14, protruding rafter 15 and retaining rib 16 can all be omitted....

The invention relates to a waterwheel-type automatic aerator, substantially composed of a motor, a reduction box, an impeller, a floating body, a bracket, a waterproof cover and the like; an air inlet is arranged on the waterproof cover, a cover is arranged on the air inlet, a surrounding ring is arranged on the periphery of the air inlet, a flange is arranged on the surrounding ring along the water facing direction, and a plurality of water blocking ribs are arranged on the two sides of the outer edge of the surrounding ring; a groove is respectively arranged on the two sides of the lower part of the waterproof cover, output shafts of the reduction box are arranged in the grooves, and the grooves on the two sides of the waterproof cover are shielded by a sealing element shell; the periphery of the waterproof cover and radiating ribs of the motor are combined to form ventilation passages; a cover is arranged on the top part of the waterproof cover, and an air inlet passage is arrangedin the non-water facing direction of the cover; the cold air enters from the air inlet passage, and the cold air is exhausted from the lower surfaces of a plurality of ventilation passages formed by the periphery of the waterproof cover and the radiating ribs of the motor to take most heat on the radiating ribs away.
Description
technical field [0001] The invention relates to an aerator, in particular to a water wheel aerator. Background technique [0002] The aerator is a life-saving and boosting equipment for fish and shrimp in aquaculture. The existing mechanical aerators mainly include waterwheel type, impeller type and water spray type. Among them, the waterwheel type aerator is used more wide. Most of the original water wheel aerators use air-cooled motors, and the motors are equipped with waterproof covers. In order to cool the motors, the waterproof covers are higher than the fan blades of the motors. The motor can be cooled by air, but this cooling wind is inside the cover. Circulation, in order to make the steam evaporated on the water surface have a rising channel, some waterproof covers have air outlet holes, which can discharge the water vapor in the cover when the aerator is not working, and cannot cool down the motor when it is working Therefore, the cooling condition of the existin...
