[Technical field to which the device belongs]

 The present invention relates to a fluid rotating structure used as a decoration for a shaped structure installed in a park, a pond in a garden, or the like.

[0002]

[Prior art]

 Traditionally, in parks and gardens, ornaments of shaped structures such as monuments in which stone spheres are placed on a base stand have been installed to entertain the public's eyes.

However, such conventional shaped structures are mainly made as still lifes of artistic creations, and are constructed so as to have no movement or mechanical means to give a slight and gradual change. Therefore, there was a problem that people would not be interested in it more than the beauty of the appearance such as the beauty of modeling, and they would soon get tired of it.

On the other hand, on the other hand, an arcuate portion is formed in the recess formed in the base, a weight sphere is placed on the arcuate portion, and a guide member having a spiral groove installed in the recess is passed. Then, a fluid rotating structure has been proposed in which pressurized water is jetted to the above-mentioned heavy-weight sphere, which floats and rotates.

Reference numerals 12 and 13 denote four pipe mounting holes formed at equal intervals in and around the central portion of the base 8 so as to penetrate the pressure chamber 10 and the lower surface. A levitation pipe 14 and a horizontal rotation pipe 15 for levitation of the sphere 11 are inserted through 13.

A well-known pressure-proof sealing material (not shown) is filled between the pipe mounting holes 12 and 14 and between the pipe mounting holes 13 and 15 to lower the base 8. Pressure adjusting valves 16 and 17 are attached in the middle of the respective floating pipes 14 and the three horizontal rotating pipes 15 facing each other.

Reference numeral 18 denotes a single main pipe that connects the pipes 14 and 15 to the pump 6, and a main valve 19 for pressure adjustment is attached in the middle of the main pipe 18.

The upper ends of the pipes 14 and 15 are in the pressure chamber 10, and the levitation pipe 14 is a direction in which a jet of pressure water is supplied to the center of the sphere 11, that is, a vertical direction here. The horizontal rotation pipe 15 is opened so as to face upward, and is opened in the circumferential direction, here, in the direction in which the jet flow of the pressure water is supplied so as to hit the lower portion of the spherical body 11.

In the fluid rotating structure having such a configuration, first, water is supplied into the water storage tank 1. Therefore, water is also supplied into the support member 2 through the communication hole 3, and the water level is supplied until the pump 6 in the support member 2 can absorb and pump the water. The water is supplied into the water storage tank 1 periodically or in a timely manner by using another pipe, a hose or the like not shown.

Then, the pump 6 is started to discharge water into the main pipe 18, and the main valve 19 on the main pipe 18 appropriately adjusts the discharge pressure of water from the pump 6. . This discharge pressure can be arbitrarily adjusted by loosening the cock of the main valve 19 to drain the water.

After performing such appropriate discharge pressure adjustment, the pressure adjusting valve 16 on the levitation pipe 14 is subsequently operated so that the pressure water injected from the end of the levitation pipe 14 is The pressure is adjusted so that the sphere 11 is floated through 10 by a predetermined pressure.

The sphere 11 is floated when the water pressure stored in the pressure chamber 10 and the injected pressure water exceed the weight of the sphere 11, and at this time, the pressure chamber 10 A part of the pressure water of sewn through the gap between the spherical body 11 and the spherical receiving portion 9 and spouts at a predetermined height on the upper surface of the base 8, and then travels along the outer peripheral surface of the base 8 to hold the water tank. It is dropped into 1 and stored (collected).

Subsequently, the pressure adjusting valve 17 on each of the horizontal rotating pipes 15 is adjusted so that the pressure water hits the three locations on the outer peripheral surface of the lower part of the sphere in a substantially horizontal tangential direction, and the pressure The water pressure is adjusted to a predetermined level at which the floating sphere 11 starts horizontal rotation.

By separately adjusting each of these three pressure adjusting valves 17, fine adjustment of the speed and direction of the horizontal rotation of the spherical body 11 can be arbitrarily performed, and each horizontal rotation is also possible. By changing the height of the pipe 15 for use, that is, the emission height of the fountain flow toward the outer circumference of the sphere 11, the velocity of the sphere 11 can be arbitrarily set.

FIG. 3 and FIG. 4 are a vertical sectional view and a plan view of a main part showing a fluid rotating structure according to another embodiment of the present invention. In this embodiment, a pipe provided at the center is provided. One pipe mounting hole 21 is provided in the base 8 so that its position is biased with respect to the mounting hole 12.

Then, one vertical rotation pipe 22 is passed through the pipe mounting hole 21, and the tip end portion of the vertical rotation pipe 22 is inside the pressure chamber 10. For example, the tip end portion of the pipe 22 is arranged in three directions. For example, it is branched into one or more.

Further, these three tip end openings 22a are oriented to rotate the sphere 11 in a substantially vertical direction by applying a jet of water to the lower part of the sphere 11.

Therefore, in this embodiment, the vertical rotation pipe 22 is provided with one pressure adjusting valve 23, and the pressure-adjusted equal pressure water is jetted from the ends of the three forked end openings 22a. It

In this embodiment, when the pump 6 is operated, the main pipe 18 is supplied with pressure water having a predetermined discharge pressure through the main valve 19, and the pressure adjusting valve 16 is used to adjust the pressure. Water is supplied into the pressure chamber 10.

Therefore, similarly to the above, the spherical body 11 slightly floats up due to the pressure in the pressure chamber 10 that has reached the above-mentioned injection pressure and the predetermined pressure, and a part of the pressure water in the pressure chamber 10 is partly in contact with the spherical body 11 and the spherical receiving portion. The gap with 9 will be sewn and spouted.

Subsequently, the pressure adjusting valve 23 provided in the middle of the vertical rotation pipe 22 is adjusted so that the pressure water is discharged from the end of the tip opening 22a branched into three branches toward the outer peripheral surface of the lower portion of the sphere 11. Make sure that the tangential direction is almost horizontal.

As a result, a force in the vertical rotation direction is applied to the levitated sphere 11, and the sphere 11 is levitated at a speed corresponding to the jet pressure of the pressure water from the tip opening 22a. It will rotate in a substantially vertical direction.

The main valve 19 provided in the middle of the main pipe 18 adjusts the total discharge pressure of the pump 6 with respect to the floating pipe 14, the horizontal rotation pipe 15, and the vertical rotation pipe 22, For example, the discharge pressure of the pump 6 is adjusted to set the discharge pressure according to the weight of the sphere 11, and functions as necessary to return the excessive discharge pressure of the pump 6 into the water tank 1.

Further, in FIG. 3, the tip of the vertically rotating pipe 22 is shown to be oriented horizontally in the pressure chamber 10. However, by vertically orienting vertically, the vertical direction relative to the spherical body 11 is also increased. Needless to say, the rotational force can be applied.

As described above, according to the present invention, the spherical body 11 is rotated while being floated by using pressured water, and the flow of water ejected from the gap between the spherical body 11 and the spherical surface receiving portion 9 is viewed, People can feel the beauty and fun of structures that move differently from still life, and they can entertain a large number of people without getting tired of watching them for a long time.

It is possible to change the gap between the spherical body 11 and the spherical surface receiving portion 9 by precisely processing a part of the surface of the spherical body 11 into a perfect circle or forming the surface slightly rough. As a result, it is possible to cause a change in the jetting state of water from this gap and complicate the movement of the sphere 11.
