On the other hand, the motor 50 is for rotating the wing portion 20 and includes a drive shaft 510 connected to the wing portion 20, and the drive shaft 510 of the motor 50 is located on the upper portion of the rotating body 10 It is preferable that the cover 520 is penetrated so that water does not flow into the rotating body 10. At this time, the rotating body 10 is formed with a space of a certain size therein and is connected to the drive shaft 510 to rotate by the motor 50.

The wing part 20 is rotatably coupled to the rotating body 10 at equal intervals by an extension shaft 210 extending from the radially outer side of the rotating body 10 into the space, and the rotating body 10 and Rotate together. Specifically, the wing portion 20 is coupled by interposing a bearing member 220 in a hole in which an extension shaft 210 formed in the center direction of the rotating body 10 is formed at regular intervals along the circumferential direction of the rotating body 10. By this, it is coupled to the rotating body 10 so that relative rotation with respect to the rotating body 10 is possible.

And, the wing angle adjustment unit 30 is to be elevated or lowered by the elevating unit 40, is provided inside the rotating body 10 and rotates the extension shaft 210 to rotate the elevating unit of the wing unit 20. The angle will be changed at the same time.

At this time, the drive shaft 510 of the motor 50 is inserted into the inside of the wing angle adjustment unit 30 and is configured to rotate the wing angle adjustment unit 30. That is, the wing angle adjustment unit 30 is rotated around the drive shaft 510 by the motor 50, and the wing unit 20 and the rotating body 10 connected to the wing angle adjustment unit 30 rotate at the same time. . Then, the wing angle adjustment unit 30 is moved up and down by the elevating and descending unit 40, and at the same time, the wing angle is changed by the wing remote control unit 30 and the wing unit 20 is rotated around the rotating body 10. do.

The wing angle adjustment unit 30 is shown in FIGS. 6 to 8, the body 310 of the cylindrical shape to which the drive shaft 510 of the motor 50 is coupled, and the body 310 so that the wing unit 20 is connected Link brackets 320 formed at regular intervals on the outside of the body, and power transmission hubs 330 installed on the lower portion of the body 310 and connected to the rod side of the elevating and descending parts 40, and the upper and lower portions of the body 310 It comprises a link member 340 connecting the bracket 320 for the link and the extension shaft 210 of the wing part 20 to convert the motion to the rotational motion of the wing part 20.

Therefore, the body 310 coupled to the drive shaft 510 is rotated around the drive shaft 510 by a motor 50, and the body (due to the power transmission hub 330 to which the rod side of the elevating and descending portion 40 is connected) 310) and the link bracket 320 and the power transmission hub 330 are moved in the vertical direction. In this process, the link member 340 connected to the link bracket 320 rotates and rotates the wing 20, thereby changing the wing angle.

Here, the link member 340 is formed in a ring shape in which both ends are orthogonal to each other, and the first link 341 having one end hinged to the link bracket 320 and the extension shaft 210 on one side are rotatable. It comprises a second link 342 in the form of a plate provided with a hinge shaft 343 that is coupled to the other side and hinged to the other end of the first link 341 on the other side. At this time, it is preferable that the first link 340 is divided into an upper body 341a in the form of an eyebolt and a lower body 341b having a female screw portion, so that the length can be varied by being fastened to each other.

As described above, both ends of the first link 341 are formed in an orthogonal ring shape, and the wings 20 extend through the second link 342 connected to the hinge link 343 to the first link 341. As it is connected to the shaft 210, even if the axial direction of the hinge coupled to the link bracket 320 and the axial direction of the extended shaft 210 are different, the first link 341 moves smoothly and the wing portion 20 Can rotate. In addition, since the first link 341 is divided into an upper body 341a and a lower body 341b and fastened to each other, the first link (in consideration of the distance between the link bracket 320 and the extension shaft 310) 341).

On the other hand, the second link 342 in the form of a plate is preferably formed with a diameter of the portion where the hinge shaft 343 is coupled is relatively smaller than the diameter of the portion where the extension shaft 210 is coupled. In addition, the link bracket 320 is formed at a 90-degree interval on the outside of the body 310, and a pair of first links 341 connected to the opposite link brackets 320 is formed to intersect. It is preferable that the 1 link 341 is inclined.

As described above, the reason why the first link 341 is inclined and the size of both sides of the second link is different is to make the most of the narrow inner space of the rotating body 10 in which the link member 340 is disposed.

At this time, the body 310 is provided with one or more grooves 315 in the longitudinal direction in which the projection 515 provided in the drive shaft 510 of the motor 50 is inserted, up and down along the drive shaft 510 of the motor 50 It is configured to rotate while moving. A plurality of protrusions 515 provided on the drive shaft 510 may be formed at equal intervals along the circumferential direction of the drive shaft 510. In this case, the grooves 315 formed in the body 310 correspond to the protrusions 515. It is preferably formed so as to be formed in more than two times.

Accordingly, the protrusion 515 is fitted to the groove 351 of the body 310 and fixed to the drive shaft 510, and when the drive shaft 510 is rotated by the motor 50, the body coupled with the drive shaft 510 ( 310) will rotate together. Of course, while the body 310 moves downward in the vertical direction by the elevating and descending portion 40, the driving shaft 510 and the body 310 maintain a coupled state, so that the body 310 is connected to the driving shaft 510 to rotate Make it possible.

To this end, the body 310 is provided with one or more grooves 315 in the longitudinal direction in which the protrusions 515 are inserted, so as to correspond to one or more protrusions 515 provided on the drive shaft 510 of the motor 50 It is preferable to rotate while moving up and down along the drive shaft 510 of (50).

 As shown in FIG. 9, the elevating and lowering portion 40 includes a cylinder 410 accommodated inside the cover member 610 provided below the casing 60, and a plurality of cylinders 410 formed along the length direction inside the cover member 610. The cylinder fixing bracket 420 which is unevenly coupled to the fixed piece 611 of the cylinder to fix the cylinder 410, and the wing angle adjusting unit 30 are connected to the upper part and the bearing 441 to the rod 440 of the cylinder 410 It is characterized in that it comprises a cylinder hub 430 that is rotatably coupled through the wing angle adjustment unit 30 to move up and down.

As such, as the cylinder 410 is unevenly coupled to the fixed piece 611 of the cover member 610 to the fixed cylinder bracket 420, the cylinder 410 is maintained in a firmly coupled state. As the rod 440 of the cylinder 410 is coupled to the cylinder hub 430 via a bearing 441, the cylinder hub 430 rotates by being coupled to the power transmission hub 330 of the wing angle adjustment unit 30 Regardless, the cylinder 410 and the rod 440 do not rotate.

When explaining the wireless communication and wireless charging the submersible pump equipped with a wireless communication and wireless charging function according to the present invention as described above are as follows.

In order to adjust the wing angle of the wing portion 20 provided in the submersible pump, the submersible pump and the external control device 1000 are not connected by wire, but the external control device 1000 and the submersible pump are wirelessly connected. Accordingly, the control signal of the external control device 1000 is received by the wireless reception module 810 to operate the hydraulic control device provided in the stepping box of the motor 50. Then, the cylinder 410 is operated by the hydraulic pressure supplied through the hydraulic control device to raise and lower the rod 440, and the wing angle adjustment unit 30 is the wing unit 20 according to the elevation of the rod 440. Changes the wing angle of

At this time, the position sensor 820 detects the rod position of the cylinder 410 and then transmits it to the external control device 1000 through the wireless transmission module 830 and the antenna 835. Therefore, it is possible to monitor the rod position of the cylinder 410 from the external control device 1000, thereby controlling the wing angle of the wing portion 20 in real time. In addition, through this, the wing angle of the wing portion 20 is adjusted to 0 degrees, that is, horizontally when the underwater motor is started, thereby minimizing load due to friction with the fluid and minimizing the starting current.

In addition, the battery 722 is used as an electricity supply source for driving the motor 50 and a wireless provided in the stepping box of the motor 50 in the external electricity supply device 1100 without connecting a cable to the battery 722 The electromagnetic signal is transmitted to the charging module 710. The wireless charging module 710 converts the received electromagnetic signal into electricity and supplies it to the wireless charging pad 721 of the power supply unit 720, and the battery 722 receives electricity from the wireless charging pad 721 and stores it. do. As such, as power is supplied without using a cable, it is not necessary to install a watertight structure for using the cable, and it is possible to prevent an electric shock accident due to cable damage. In addition, as the cable is not used in the flange portion connecting the motor 50 and the pump, it is easy to separate or reassemble the motor 50 and the pump for maintenance and maintenance costs are reduced.

On the other hand, with reference to Figures 10 and 11 will be described with respect to adjusting the wing angle of the wing.

When the motor 50 is operated to drive the pump, the drive shaft 510 rotates, and the blade angle adjustment unit 30 rotates by the drive shaft 510. That is, since the driving shaft 510 is coupled to the body 310 of the wing angle adjustment unit 30, the body 310, the power transmission hub 330, and the link member 340 rotate together with the driving shaft 510. do. And, since the link member 340 is connected to the extension shaft 210 of the wing part 20, the wing part 20 is also rotated according to the rotation of the wing angle adjustment part 30, and the wing part 20 is rotated. The rotatable body 10 coupled as possible is also rotated around the drive shaft 510. Therefore, water flow is generated by the wing portion 20 and water is pumped.

In addition, when the motor 50 is operated, the cylinder 410 of the elevating unit 40 is operated to raise or lower the rod 440. At this time, since the cylinder hub 430 coupled to the rod 440 is connected to the power transmission hub 330 of the wing angle adjustment unit 30, the wing angle adjustment unit 30 rotates according to the operation of the cylinder 410. It moves up and down inside (10).

 When the wing angle adjustment unit 30 moves up and down, the wing angle 20 is rotated by the link member 340 connected to the link bracket 320 to change the wing angle. That is, the lower body 341b of the first link 341 constituting the link member 340 is hinged to the link bracket 320 and can move in the vertical direction, but the second link 342 has a wing ( Since the extension shaft 210 of 20) is connected and does not move in the vertical direction, the upper body 341a of the first link and the second link 342 are connected by the hinge shaft 343, so that the principle of the connecting rod is By this, the second link 342 rotates about the extension shaft 210 of the wing part 20 while the link bracket 320 moves in the vertical direction. Accordingly, the wing angle is changed while the wing portion 20 connected to the extension shaft 210 rotates together with the extension shaft 210.

The above description is illustrative of the present invention, and the embodiments disclosed in the specification are not intended to limit the technical idea of the present invention, but are intended to explain the present invention. Various modifications and variations will be possible without departing from the technical idea of. Therefore, the protection scope of the present invention is to be interpreted by the matters described in the claims, and technical matters within the equivalent scope thereof should be interpreted to be included in the scope of the present invention.
