DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional side view showing a pump which is an example of a fluid drive device according to the present invention, and FIG. 2 is a perspective view showing a part in detail. The pump 2 is composed of a ring body 4, a supporting means 6 for rotatably supporting the ring body 4, a driving means 8 for the ring body 4, a plurality of blade bodies 10 attached to the ring body 4, and the like.

The ring 4 has a circular shape, and a plurality of holes 12 penetrating in the radial direction are formed at regular intervals in the circumferential direction. The support means 6 includes two support ring bodies 16, each of which has substantially the same diameter as the ring body 4 and has a gap between the ring body 4 and both sides of the ring body 4. The center of the ring body 4 is aligned with that of the ring body 4. The two support ring bodies 16 are connected and fixed to each other at a plurality of circumferentially spaced positions by strip-shaped connecting members 14 arranged inside the support ring body 16.

A groove 18 continuous in the circumferential direction is formed on the side surface of the support ring body 16 on the ring body 4 side, and both side portions of the ring body 4 are loosely inserted in the groove 18, and as a result, the ring body is formed. 4 is rotatably supported by these support rings 16. In addition,
A seal material (not shown) is interposed between the side wall of the groove 18 of the support ring body 16 and both side portions of the ring body 4 to ensure watertightness. Further, various known structures using bearings are used to form the ring. The rotatably supporting body 4 is optional.

The drive means 8 is composed of an electric motor 28, a gear 30, a tooth portion 32 formed on the outer peripheral surface of the ring body 4, and the like. The electric motor 28 is arranged outside the support means 6 so that the rotation shaft 34 thereof is perpendicular to the ring surface of the ring body 4, and is fixed to the support ring body 16. The gear 30 is the tip of the rotation shaft 34 of the motor 28. It is attached to the portion and meshes with the tooth portion 32 of the ring body 4.

The plurality of blades 10 extend radially outside the ring body 4 with the ring body 4 as a center, and are arranged in each hole 12 of the ring body 4. As shown in detail in FIGS. 2 and 3 (A), (B), and (C), each blade 10 has a ship bottom-shaped recess 10A in the present embodiment.
The blades 10 are arranged on the ring body 4 with the direction of rotation of the ring body 4 facing the direction of rotation. Then, the end 36 of each blade 10 on the side of the ring 4 is fixed to the outer surface of the ring 4, and in this embodiment, the end 3 is formed.
6 surrounds the hole 12 except the front of the hole 12 in the rotation direction of the ring body 4 (arrow A). Also, the blade body 10
A tube 10B is formed at the tip of the end portion 36 side of
A slit 10C is formed in the tube 10B in the axial direction as shown in detail in FIG. Therefore, by inserting the tube 10B into the hole 12 of the ring body 4, the blade body 10 is fixed to the ring body 4 by utilizing the spring force of the tube 10B.

As shown in FIG. 1, the entire pump 2 has a pipe 38.
Is installed in the middle of. The diameter of the pipe 38 is almost the same as that of the support ring body 16, and the ring surface of the ring body 4 is the pipe 38.
Are arranged so as to be substantially perpendicular to the extending direction of the. The ends of the pipes 38 on both sides of the pump 2 are fixed to the corresponding side surfaces of the support ring 16.

In the pump 2 thus constructed,
When electric power is supplied to the electric motor 28, the electric motor 28 rotates, and the rotational force thereof is transmitted to the ring body 4 via the gear 30 mounted on the rotating shaft 34 and the tooth portion 32 of the ring body 4, and the ring body 4 is a blade body. It rotates together with 10 in the direction of arrow A (FIG. 2). As the blade body 10 rotates, the water B outside the pipe 38 is captured by the bottom-shaped blade bodies 10, and the ring body 4
Is introduced into each of the holes 12 and flows into the inside of the ring body 4 through the holes 12, and flows through the pipe 38 to be transported.

As described above, the pump 2 of this embodiment is provided with the piping 3
Since it is installed in the form integrated with the pipe 38 in the middle of 8,
It is not necessary to secure a place for installing the pump as in the conventional case, and a pipe for connecting the pump and the pipe is also unnecessary. Therefore, the pump can be installed and operated without taking up space.

In the above embodiment, the electric motor 28 is connected to the pipe 3
Although the electric motor 28 is arranged inside the pipe 38 and the tooth portion 32 is formed on the inner peripheral surface of the ring body 4 as shown in FIG. Can be transmitted to the ring body 4. In this case, since the protrusion by the electric motor 28 is eliminated on the outside of the pipe 38, the shape can be made more compact.

Further, in the above embodiment, the rotational force of the electric motor 28 is transmitted to the ring body 4 via the gear. However, instead of the gear, a friction type roller pressed against the outer peripheral surface of the ring body 4, for example, may be used. It is possible.

The pump 2 can be provided at the end of the pipe 40 as shown in FIG. 6 in addition to being arranged in the middle of the pipe as in the above embodiment. In this case,
The pipe 4 is captured by the blade body 10 and is passed through the hole 12 of the ring body 4.
The water B flowing into 0 flows in a fixed upper direction on the drawing.

Further, in the above-mentioned embodiment, each blade body 10 is assumed to extend radially outside the ring body 4, but other than such a structure, for example, it is shown in FIGS. 7 (A) and 7 (B). Thus, it is possible to extend the blade body 42 in the extending direction of the pipe 40. With such a configuration, the diameter of the entire pump including the blade body 42 can be made small, and the size can be reduced to save more space. In addition to the shape of the blade body shown in FIG. 7, a sectional side view of FIG.
It is also effective to have a rectangular shape in a front view as in the blade body 42 shown in the sectional front view of (B) and the top view of (C), and in that case, the amount of liquid that can be captured can be increased. it can.

[0020]

As described above, in the fluid drive system of the present invention, when the ring member rotatably supported by the supporting means is rotated by the driving means, the blade body rotating together with the ring body causes the outside of the ring body to rotate. Fluid is trapped, guided to the hole formed in the ring body, and flows into the inside of the ring body through the hole. Therefore, it is possible to arrange the ring body in the middle of the pipe, take in the fluid outside the pipe into the inside of the pipe, and transport the inside of the pipe.

Therefore, in the fluid drive device of the present invention, since it can be installed in the middle of the pipe in a form integrated with the pipe, it is not necessary to secure a place for installing the fluid drive device as in the conventional case. Moreover, a pipe for connecting the fluid drive device and the pipe is not necessary. Therefore, the fluid drive device can be installed and operated without taking up space.
