  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  The rotating body 1 is rotated by the jet power of the water W by jetting the water W from the jet section 2, while the rotating body is rotated by the jet power of the water W by jetting the water W from the jet section 3 for speed adjustment. The rotational speed of 1 is suppressed, and the rotating body 1 rotates at an optimum speed. At this time, for example, a predetermined fountain design D is formed by the water W ejected from the ejection portion 2 provided on the rotating rotating body 1.

  This fountain design D can be shaped with a relaxing and high healing effect, for example, by rotating at low speed.

  Therefore, rotating the rotator 1 and suppressing the rotation speed of the rotator 1 is a structure that can be achieved with only the water jet power. A complicated structure (large-scale electronic device) such as a controller is unnecessary, so that the cost is low. Moreover, since an electronic device that easily breaks down with water W is also unnecessary, it is difficult to break down and maintenance is good. In addition, the present invention is a structure that can be used anywhere as long as there is a water source, and is not easily restricted by the installation location.

  In the second aspect of the invention, by appropriately adjusting the ejection angle of the speed adjusting ejection section 3, for example, an error that occurs in manufacturing when matching with the ejection section 2, a difference in water pressure that varies depending on the installation location, etc. Adjustment according to the conditions becomes possible.

  Moreover, invention of Claim 3 can model various desired fountain designs D simply and reliably.

  That is, when the fountain design D is formed with the water W ejected from the rotating rotator 1 by rotating the rotator 1 with the jet power of the water W as in the present invention, the desired fountain design D is formed. The jet trajectory (shape) of the water W, which is a condition, is determined by the jet angle of the water W, but due to the structure, the rotational speed of the rotating body 1 increases or decreases depending on the jet angle of the water W. Therefore, if this rotational speed is not appropriate, the desired fountain design D may not be formed.

  That is, for example, there is a case where a desired fountain design D is desired to be formed without increasing (or decreasing) the rotational speed of the rotating body 1, and it is necessary to cope with this.

  In this respect, since the ejection angle of the ejection part 2 and the speed adjusting ejection part 3 is adjustable, it is possible to easily and reliably meet the above-described requirements. Specifically, for example, the ejection part 2 ejects from the ejection part 2. When forming a desired fountain design D in which the water W has a jet trajectory (shape) and the rotational speed of the rotating body 1 are aligned, the jet angle of the jet part 2 is adjusted. By determining the ejection trajectory (shape) of the water W and adjusting the ejection angle of the speed adjusting ejection section 3 to determine the rotational speed of the rotating body 1, the desired fountain design D is reliably formed. It will be. In addition, for example, when you want to enlarge the fountain design D that you want to obtain according to the size of the installation location, as well as when you want to make it smaller, or when you want to deform the fountain design D itself, various requests are made. Even if it exists, it can respond easily and reliably by adjusting the ejection angle of each of the ejection part 2 and the ejection part 3 for speed adjustment.

  A specific embodiment of the present invention will be described with reference to the drawings.

  In this embodiment, a rotator 1 is rotatably provided in a fountain body 4 provided continuously with a water supply unit 5, and a jet part 2 for jetting water is provided on the rotary body 1, and water jetted from the jet part 2.

  As shown in FIG. 3, the water supply unit 5 has a structure in which a submersible pump device 5b for pumping water W is provided at the base end of the water supply pipe 5a. It is provided in the installation location to be installed, and is disposed in a cylindrical installation portion 7 for placing and arranging the fountain body 4 on the upper portion. Reference numeral 5c is a valve for adjusting the amount of water (for adjusting the height of the fountain design D formed with the water W to be ejected).

  The fountain body 4 is a cylindrical body formed of an appropriate metal member as shown in FIGS. 2 and 3, and a water pipe 8 connected to the water supply pipe 5 b is provided at a lower portion in the fountain body 4. Is provided.

  The water pipe 8 is formed of an appropriate metal member as shown in FIG. 3, and the lower end of the water pipe 8 is connected to the tip of the water supply pipe 5b and both ends thereof. The water W supplied from the water supply pipe 5 b passes through the water pipe 8 and is supplied into the rotating body 1 through the fitting connection member 10 to be fitted.

  Further, a shaft portion 1B of the rotating body 1 to be described later is rotatably fitted to the upper end portion of the water conduit 8, and an annular shape is formed between the outer peripheral surface of the water conduit 8 and the inner peripheral surface of the shaft portion 1B. The packing 11 is provided.

  In addition, a bearing portion 9 for bearing the rotating body 1 (shaft portion 1B) is provided at an upper portion of the fountain body 4.

  As shown in FIG. 3, the bearing portion 9 is configured by providing a ball bearing portion 13 between the outer periphery of the shaft portion 1 </ b> B at a vertical position in a space where the shaft portion 1 </ b> B of the rotating body 1 can be disposed.

  Further, in this embodiment, a cylindrical bottom member 12 is provided at the lower end of the fountain body 4, and a convex connecting portion that is fitted and connected to the upper opening of the installation portion 7 at the bottom of the bottom member 12. 12 a is provided, and the connecting portion 12 a is configured to be fitted and connected to the fitted connecting member 10.

  Further, a drainage unit 6 is provided at the lower part of the fountain body 4.

  As shown in FIG. 3, the drainage portion 6 is configured by providing a pipe member having an L shape in a side sectional view through the fountain body 4 and the bottom member 12.

  Accordingly, excess water that is supplied into the rotating body 1 in a pressurized state and is not ejected by the ejection part 2 and the speed adjustment ejection part 3, that is, water W leaked from between the shaft part 1B and the water conduit 8 is drained. .

  As a result, unnecessary excess water is drained, and the water W supplied to the later-described ejection section 2 and the speed adjustment ejection section 3 is stable without being excessively pressurized. From the ejection section 2 and the speed adjustment ejection section 3 It is possible to prevent as much as possible the ejection of the pulsating water W.

  The rotating body 1 is provided at the distal end (upper end) of the fountain body 4 so as to be rotatable (rotatable) in the horizontal direction.

  Specifically, the rotating body 1 is a hollow body formed of an appropriate metal member, and is provided with a shaft portion 1B inserted and disposed in the bearing portion 9 of the fountain body 4, and an upper end portion of the shaft portion 1B. It is comprised with the nozzle connection part 1A provided.

  As shown in FIG. 3, the shaft portion 1 </ b> B is a cylindrical body and is rotatably supported via a ball bearing portion 13 that constitutes the inside of the bearing portion 9.

  As shown in FIGS. 2 and 3, the nozzle connecting portion 1 </ b> A is a cylindrical body having a ceiling wall 1 a, and a plurality (total of six) of the ejection portions 2 and the speed adjusting ejection are provided on the side portion (side peripheral surface). Through holes 1b that penetrate the portion 3 are formed at equally spaced positions.

  The through-hole 1b is a screw hole, and the through-hole 1b of the through-hole 1b that is screwed and connected to the ejection portion 2 is formed in the horizontal direction, and the through-hole 1b that is screwed and connected to the speed adjustment jet portion 3 Is formed in the downward inclination direction.

  In addition, the nozzle connecting portion 1A is provided with a conical branch member 14 on the inner surface of the top wall 1a, and the branch member 14 sideways (rotates the water W supplied into the rotating body 1. The water W is evenly branched to both the jetting part 2 and the speed adjusting jetting part 3 by guiding to the outer side of the moving center).

  Therefore, in the present embodiment, the ejection part 2 and the speed adjustment ejection part 3 branch out and eject the water W of the same water supply part 5 provided continuously with the rotating body 1.

  In addition, in this embodiment, the rotating body 1 that can rotate in the horizontal direction is adopted as the rotating body 1, and the ejection unit is configured to eject water W in the direction in which the rotating body 1 is rotated above the rotating body 1. 2 is provided on the rotating body 1 and the speed is such that the water W is spouted in a direction to generate a rotating force in a direction opposite to the rotating force generated by the jet power that spouts the water W from the jetting portion 2 below the rotating body 1. The adjustment jetting part 3 is provided in the rotating body 1 or the jetting part 2.

  Specifically, the ejection part 2 is formed of an appropriate metal member as shown in FIGS. 2 and 3 and is connected to the straight part 2A and the straight part 2A through a bent part 2C. The tip opening portion of the bent nozzle tube 2 having the rising portion 2B is set as the ejection hole 2a.

  Further, a screw portion 2b that is screwed and connected to the through hole 1b of the rotating body 1 is formed at the base end portion of the jetting portion 2 (linear portion 2A). (Surrounding surface portion) is arranged in a radially projecting state from the rotation center of the rotating body 1, and is linearly connected to the rotating body 1 so that the linear portion 2A is in a horizontal state.

  Therefore, the ejection angle of the water W ejected from the ejection section 2 (ejection hole 2a) can be adjusted (see FIG. 4), and therefore the ejection section 2 is directed above the rotator 1 to rotate the rotator 1. The water W is jetted out (see FIG. 6), and by adjusting the jetting angle, the jet trajectory (shape) of the water W and the rotation speed of the rotating body 1 can be varied.

  In this embodiment, the jet part 2 has a rod-like nozzle structure protruding from the rotary body 1. However, the rotary body 1 may have a structure in which the jet hole, the water spray hole and the water outlet hole are directly provided. The jet power may not be dependent only on the water pressure, and for example, the jet hole 2a may be provided with a throttle adjusting function to vary the jet power, and the number of the jet parts 2 can be changed as appropriate.

  As shown in FIGS. 2 and 3, the speed adjusting jet part 3 is formed of an appropriate metal member, and has a configuration in which a plurality of jet holes 3 a are provided in the peripheral wall of the linear nozzle tube body 3. .

  In addition, a screw portion 3 b that is screwed and connected to the through hole 1 b of the rotating body 1 is formed at the base end portion of the nozzle tube body 3, and the side of the rotating body 1 is radiated from the rotation center of the rotating body 1. The nozzle tube body 3 is connected to the rotating body 1 in a downwardly inclined manner so as to be pivotable so that the protruding tip portion is positioned below.

  Therefore, the jet angle of the water W jetted from the speed adjusting jet part 3 (spout hole 3a) can be adjusted (see FIG. 5), so that the speed adjusting jet part 3 is jetted below the rotating body 1. The water W is ejected in a direction that generates a rotational force in a direction opposite to the rotational force generated by the jet power that ejects the water W from the portion 2 (see FIG. 6), and the rotation of the rotating body 1 is adjusted by adjusting the jet angle. The speed can be adjusted. Moreover, the adjustment which makes the rotational speed of the rotary body 1 high by adjustment of the jet angle of the jet part 3 for speed adjustment is also possible.

  The speed-adjusting ejection portion 3 composed of the linear nozzle tube 3 is provided in a projecting state in the radial direction at the side of the rotating body 1, so that a good rotational force (speed-adjusted rotation) can be efficiently obtained from the moment relationship. In addition, because of the long structure, it is easy to grasp and the ejection angle can be easily adjusted.

  In the present embodiment, the speed adjusting jet part 3 has a rod-like nozzle structure projecting from the rotating body 1, but the rotating body 1 may have a structure in which a jet hole, a water spray hole, or a water outlet hole is directly provided. The jet power of the water W does not depend only on the water pressure, for example, the jet hole 3a may be provided with a throttle adjusting function so that the jet power can be varied, and the nozzle tube 2 of the jet part 2 is provided with the jet hole 3a. This may be used as the speed adjusting jet part 3, and the number of the speed adjusting jet parts 3 may be appropriately changed.

  Since the present embodiment is configured as described above, when the water W is ejected from the ejection part 2, the rotating body 1 is rotated by the ejection force of the water W, while the water W is ejected from the speed adjusting ejection part 3. Thus, the rotational speed of the rotating body 1 is suppressed by the jet power of the water W, and the rotating body 1 rotates at an optimum speed. At this time, for example, a fountain design D like a spiral is formed by the water W ejected from the ejection section 2 provided on the rotating rotating body 1 (see FIG. 1). This fountain design D allows you to enjoy the appearance of the water as well as the sound of water W, and you can expect negative ion effects and insect repellent effects.

  Therefore, according to the present embodiment, the structure in which the rotating body 1 is rotated and the rotational speed of the rotating body 1 is suppressed only by the water jet power. Costs are low because complicated structures (large-scale electronic devices) such as drive sources and controllers are unnecessary, and maintenance is also difficult because these electronic devices that are easily damaged by water W are also unnecessary. The property is also good. Further, this embodiment has a structure that can be used anywhere as long as there is a water source and is not easily restricted by the installation location.

  Further, in this embodiment, the speed adjustment of the rotating body 1 is not based on the drive source as described above but exhibits an excellent operational effect. For example, the speed adjustment via a friction member is also possible. Exhibits superior operational effects.

  That is, when adjusting the speed via the friction member, it is very troublesome to adjust the friction coefficient in the friction member and the selection of the material, and the speed is not adjusted due to wear after repeated use. However, in this embodiment, such a problem does not occur.

  Further, in this embodiment, since the ejection angle of the speed adjustment ejection section 3 is provided to be adjustable, the ejection angle of the speed adjustment ejection section 3 is appropriately adjusted, for example, when matching with the ejection section 2 is performed. Adjustment according to conditions, such as the error which arises above and the difference in the water pressure which changes with installation places, becomes possible.

  Further, in the present embodiment, the ejection angles of the ejection section 2 and the speed adjustment ejection section 3 are provided so as to be adjustable. Therefore, the ejection angle (shape) of the water W is determined by adjusting the ejection angle of the ejection section 2. And by adjusting the jet angle of the jet part 3 for speed adjustment and determining the rotational speed of the rotary body 1, various desired fountain designs D can be modeled easily and reliably.

  In addition, in this embodiment, the rotating body 1 that can rotate in the horizontal direction is adopted as the rotating body 1, and the ejection unit is configured to eject water W in the direction in which the rotating body 1 is rotated above the rotating body 1. 2 is provided on the rotating body 1 and the speed is such that the water W is spouted in a direction to generate a rotating force in a direction opposite to the rotating force generated by the jet power that spouts the water W from the jetting portion 2 below the rotating body 1. Since the adjustment jetting part 3 is provided in the rotating body 1 (or the jetting part 2), it is possible to form a desired jetting design D by clearly dividing the functions of the jetting parts 2 and 3.

  Specifically, a desired fountain design D is formed above the fountain device by the water W ejected from the ejection section 2, while the water W ejected from the speed adjustment ejection section 3 is below the rotating body 1 where the water W is inconspicuous. It can be made not to interfere with the fountain design D formed by the water W ejected from the ejection part 2. Note that the fountain design D may also be actively formed by the water W ejected from the speed adjusting ejection section 3.

  Further, in this embodiment, the speed adjusting jet part 3 has a configuration in which the jet hole 3 a is provided in the peripheral wall of the linear tube 3, and the radial direction from the rotation center of the rotary body 1 to the side part of the rotary body 1. Since it is provided in a projecting state, a moment for rotating the rotating body 1 is obtained, and a good speed suppressing effect is surely obtained.

  Further, in this embodiment, since the speed adjusting jetting part 3 is provided on the rotating body 1 so as to be pivotable and the jetting angle of the jetting hole 3a can be adjusted freely, the rotational speed of the rotating body 1 is delicately suppressed. Adjustment can be performed satisfactorily.

  Further, in this embodiment, the speed adjusting jet part 3 is provided on the rotating body 1 so as to be inclined downward so that the projecting tip part is located below, so that the jet from the speed adjusting jet part 3 is also ejected at this point. The water W can be made inconspicuous.

  Further, in the present embodiment, the ejection portion 2 has an ejection hole 2a formed at the tip opening portion of the bent tubular body 2 having a straight portion 2A and a rising portion 2B that rises and continues to the straight portion 2A via a bent portion 2C. Since the linear portion 2A is provided on the rotating body 1 so as to be pivotable and the ejection angle of the ejection hole 2a is adjustable, the entire nozzle tube 2 constituting the ejection section 2 is configured, for example. Compared to the case of bending, by having the straight portion 2A, the water W is accelerated by the straight portion 2A, and clogging of dust and dirt in the nozzle can be prevented as much as possible. This has been confirmed by experiments.

  Moreover, since the present Example has the drainage part 6 which drains the surplus water which is supplied in the rotating body 1 in a pressurized state and which is not ejected by the ejection part 2 and the speed adjustment ejection part 3, the unnecessary surplus water is thereby removed. The water W that has been drained and is supplied to the jet part 2 and the speed adjusting jet part 3 to be described later is not excessively pressurized and stabilized, and the water W that has pulsated from the jet part 2 and the speed adjusting jet part 3 Ejection can be prevented as much as possible.

  Further, in this embodiment, the ejection part 2 and the speed adjustment ejection part 3 are configured to branch out and eject the water W of the same water supply part 5 that supplies the water W to the rotating body 1. It becomes a very efficient structure.

  The present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate.
