Description

Waterproof component and motor device using it

The present invention relates to a motor, in particular to a waterproof component suitable for an aerator and a motor device using the waterproof component.

Farmers usually use a lot of waterwheels to provide enough oxygen for fish. Since there is no sunlight at night, the concentration of carbon dioxide in the water increases while the concentration of oxygen decreases. Therefore, the concentration of dissolved oxygen in the breeding pond must be increased at night. Once the blades of the waterwheel are stuck and burned, the dissolved oxygen concentration in the pond cannot be smoothly increased, and the fish in the breeding pond will die due to lack of oxygen. At this time, in addition to the need for an emergency supply of extra power, monitoring technology must also be used to transmit information about changes in the dissolved oxygen concentration. At present, the aquaculture industry mostly uses physical circuits for monitoring, and the system is in line with availability; however, it may lose the flexibility to detect water quality because of the use of fixed-point collection of water bodies.

At present, in the aquaculture industry, since ordinary artificial breeding ponds cannot flow like river water or sea water, the breeding ponds often have insufficient oxygen content, which will lead to the death of plants in the breeding ponds. Therefore, farmers usually install an aerator in the breeding pond to increase the oxygen content in the breeding pond. In the traditional water pumping and aeration, the aerator includes a floating rack unit that can float on the water surface, and a water pumping unit installed on the floating rack unit. After the aerator is started, the water in the breeding pond is splashed into the air through the water pumping unit, mixed with the oxygen in the air, and then falls back into the breeding pond, thereby increasing the oxygen content of the breeding pond.

However, when the water catching unit splashes the water in the breeding pond into the air, part of the water will splash on the motor. Therefore, it will be prone to failure and short life of the motor over a long period of time. It must be shut down in turn during maintenance and repairs. Less maintenance costs.

The drainage hole penetrates the waterproof element. The duct is connected to the chamber of the waterproof element through the drainage hole, so as to allow the liquid flowing into the chamber to flow into the duct through the drainage hole and be discharged from the waterproof element to the external environment along the duct.

In one embodiment, the rotating shaft in the waterproof element does not touch or partially touch the inner wall of the chamber.

In one embodiment, the bottom of the waterproof element has an inclined surface, and the inclined surface is inclined downward along the drainage hole to provide the liquid to flow down to the conduit along the inclined surface.

In an embodiment, the waterproof element has a first open end and a second open end, the second open end and the first open end are respectively located on two opposite sides of the waterproof element, and the first open end faces the motor body.

Please refer to FIG. 1 and FIG. 2, where FIG. 1 is a schematic diagram of an aerator according to an embodiment of the present invention; FIG. 2 is a schematic diagram of a waterproof assembly according to an embodiment of the present invention. Fig. 2 is an enlarged view indicated by the frame line II of Fig. 1.

The aerator is an important equipment for life-saving and promoting fish and shrimp and other aquatic products in aquaculture. The existing mechanical aerators mainly include waterwheel, jet, and impeller types. This embodiment exemplifies but is not limited to the waterwheel type aerator 100.

As shown in FIG. 1, the aerator 100 includes a frame 110, a floating unit 114 and a water pumping unit 116. The floating unit 114 is a floating body, such as a pontoon or other buoyant element, which is arranged under both sides of the frame 110 to support the frame 110 to float on the water.

The aerator 100 may, for example, adopt a motor or be replaced with other suitable power elements in practice. The motor, such as but not limited to a permanent magnet motor, a DC motor, or other power components, is assembled on the frame 110 of the aerator 100 and is located between the two water pumping units 116.

The motor includes a motor main body 102 and a rotating shaft. The motor main body 102 is connected to the rotating shaft and extends from the inside of the motor main body 102 toward a side surface of the motor main body 102. The motor body 102 may include a rotor, a stator, and electronic related components. The motor main body 102 is provided with a motor control unit 108 connected to the motor main body 102 and configured to control the action of the motor main body 102 to drive the rotation shaft of the motor.

The coupling element 106 couples the rotating shaft of the motor main body 102 and the transmission rod 112 of the water pumping unit 116. The water pumping unit 116 is sleeved on the end of the transmission shaft 112. The supporting seat 120 of the aerator 100 is set on the frame 110, and is located between the water pumping unit 116 and the motor main body 102 of the aerator 100 and adjacent to the water pumping unit 116. The support base 120 has a through hole. The transmission shaft 112 passes through the through hole of the support base 120, so that the support base 120 is used to fix the transmission shaft 112.

When the motor main body 102 drives the rotation shaft of the motor to operate, it will drive the transmission shaft 112 of the aerator 100 to rotate. At this time, the water pumping unit 116 of the aerator 100 rotates with the rotation of the transmission shaft 112, so that the water pumping unit 116, such as the multiple impellers 118 on the pumping wheel, beats and shakes the water surface in turn to generate splashes and turbulence, increasing the water body and The contact area of air and the formation of water flow. When the water splashes into the air, it mixes with the oxygen in the air and then falls into the breeding pond to increase the amount of dissolved oxygen in the breeding pond, so that the air naturally enters the breeding pond.

However, during the operation of the aerator 100, the water pumping unit 116 beats and shakes the water surface, so that impurities in the water, such as seawater, salt, etc., flow into the motor main body 102 along with the water, which will damage the components of the motor main body 102. Therefore, it is worth noting that the embodiment of the present invention is provided with a waterproof component, such as but not limited to a motor suitable for the aerator 100.

As shown in FIGS. 1 and 2, the waterproof component includes a waterproof element 104 and a pipe 130. The waterproof element 104 covers a part of the transmission shaft 112 along one side of the motor main body 102 to form a cavity in the waterproof element 104. The transmission shaft 112 in the waterproof element 104 may not touch or partially contact the inner wall of the cavity, and the space between the transmission shaft 112 and the inner wall of the cavity of the waterproof element 104 forms a cavity.

The waterproof element 104 may be, for example, but not limited to, a waterproof cover or other waterproof elements, such as a waterproof membrane, etc., configured to prevent water from overflowing and penetrating into the interior of the motor main body 102. The waterproof cover can be made of plastic, rubber or other materials. The waterproof element 104 has a first open end and a second open end. The second open end and the first open end are respectively located on two opposite sides of the waterproof element 104. The first open end of the waterproof element 104 faces the motor main body 102. The second open end faces the water pumping unit 116 of the aerator 100. For example, the opening size of the first open end is larger than the opening size of the second open end.

The waterproof element 104 has a drain hole, and the drain hole penetrates the bottom of the waterproof element 104. It should be understood that the shape, size, number, and position of the drainage holes of the waterproof element 104 can be adjusted according to actual requirements. The bottom of the waterproof element 104 may have an inclined surface, and the inclined surface is inclined downward along the drainage hole. The chamber in the waterproof element 104 communicates with the duct 130 through a drain hole.

During the operation of the aerator 100, the water pumping unit 116 beats and moves the water surface to make the water splash toward the motor main body 102, and the splashed liquid enters the waterproof element 104 from the first or second open end of the waterproof element 104 After the chamber, it will flow down to the duct 130 along the inclined surface of the waterproof element 104, and be discharged to the external environment through the duct 130, so as to prevent the liquid from splashing into the motor main body 102, so as to prevent impurities in the liquid such as salt of sea water. This causes damage to the internal components of the motor main body 102.

In summary, the beneficial effect of the present invention is that the present invention provides a waterproof assembly and a motor device using the waterproof assembly. The waterproof assembly is arranged on one side of the motor body, so that liquids such as moisture and impurities contained therein have not yet splashed into the motor. Inside the main body, it has flowed from the chamber of the waterproof component to the duct through the drainage hole, and discharged to the external environment along the duct, so as to effectively prevent the liquid from rusting the components inside the motor main body or the impurities contained in the liquid from getting stuck on the components and affecting the motor. The rotation of the shaft can prolong the service life of the motor.
