Description

[Detailed Description of the Invention] The present invention relates to a fountain device equipped with a rotating outer box.

As a conventional fountain device of this kind, a patent application was filed in 1983.
Specification No. 75628 (see Japanese Patent Application Laid-open No. 193757/1983)
There are some that have been disclosed.

That is, as shown in FIG. 1 and FIG.
A cylindrical support 3 formed in a pressure water supply passage 3a connected to the
Next, an outer box 4 formed into a square tube shape made of a shiny metal material such as stainless steel and having a polygonal columnar outer circumferential surface 4a with a mirror surface is attached to bearing members 5, 5...
It is rotatably supported in an externally fitted manner via the . An injection port 6 communicating with the supply passage 3a is provided at the upper part of the support 3, and a dome-shaped injection water dispersion body 7 is provided directly above the injection port 6. The jet water jetted upward from the jet nozzle 6 is dispersed in all directions by the jet water dispersion body 7, so that a fountain is formed that follows a falling path that surrounds the outer peripheral surface 4a of the outer box 4. is being done. Further, a plurality of jet nozzles 8, 8, . Then, this jetted water collides with the water receiving blades 9, 9... provided on the inner circumference of the outer box 4,
This collision action causes the outer box 4 to rotate clockwise in FIG. 2.

Therefore, according to the fountain device having such a configuration,
A curtain-shaped fountain surrounding the outer circumferential surface 4a of the outer box 4 is formed, and the outer circumferential surface 4 of the outer box 4 rotates.
Since a has a polygonal prism-like mirror surface, the light reflected by the outer circumferential surface 4a changes as the outer box 4 rotates, giving an extremely beautiful impression to the viewer and producing an excellent fountain effect. It will be done.

However, in the case of the above-mentioned fountain device, even if an attempt is made to change the fountain form, which is a combination of the fountain shape caused by the water jetted from the jetting port 6 and the rotation of the outer box 4 due to the jetted water from each jetting nozzle 8, The changes become monotonous, and we cannot expect a richly varied fountain effect.

That is, since the injection port 6 and each injection nozzle 8 are all connected to the same supply passage 3a, no matter how you increase or decrease the amount of water sent from the water supply channel 2 to the supply passage 3a, the injection water and the The intensity changes are the same, and the fountain shape changes as the jetted water changes, and the rotation (rotation speed) of the outer box 4 as the jetted water changes.
This means that changes in the shape of the fountain are always carried out while maintaining a constant relationship, and as a result, changes in the form of the fountain inevitably become monotonous.

The technical problem to be solved by the present invention is to enable the shape of the fountain and the rotation of the outer box to be changed individually.

The technical means taken to solve the above technical problem is to independently provide a jet water supply passage that communicates with the jet nozzle and a jet water supply passage that communicates with the jet nozzle in the support body, and This is because the separate water supply channels were connected to each other.

Since the injection water supply passage communicating with the injection port and the injection water supply passage communicating with the injection nozzle are each provided independently, the amount of water sent from each water supply channel to each supply passage can be increased or decreased. The water jetted from the jetting port and the water jetted from the spouting nozzle can be changed independently and freely, and the shape of the fountain and the rotation of the outer box can be changed separately.

According to the present invention, since the shape of the fountain and the rotation of the outer box can be changed individually in this way, the shape of the fountain can be diversified by combining the two, and a variety of extremely excellent fountain effects can be achieved. It can be played.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 5.

The fountain device shown in FIG.
is rotatably supported externally.

The support body 12 includes a cylindrical support part 14 whose upper surface is closed by an upper wall 14a, and a cylindrical support part 14 having a larger diameter than the support part 14 and concentrically connected on the upper wall 14a of the support part 14. It consists of a jet water guide section 15.
A plurality of injection ports 1 are provided on the upper wall 14a of the support portion 14.
6 and 16 are bored at equal intervals in the circumferential direction, and a plurality of jet nozzles 1 as shown in FIG.
7, 17... are formed. Note that the upper jet nozzle group 17, 17... and the lower jet nozzle group 1
7, 17... are arranged so as to deviate from each other by a predetermined angle in the circumferential direction.

Further, the support body 12, that is, the support portion 14 has a water injection passage 1 that communicates with the injection ports 16, 16, . . .
8 and a jet water supply passage 19 communicating with the jet nozzles 17, 17, . . . are provided independently. That is, upper and lower partition walls 14b and 14c are provided in the support part 14 to divide the inside of the support part 14 into three upper and lower chambers.
At the same time, a pipe body 20 is provided extending from the upper partition wall 14b to below the lower partition wall 14c, and the pipe body 2
The upper end of the tubular body 20 is opened 20a into the upper chamber 21 divided by the upper wall 14a and the upper partition wall 14b, and the lower end of the tube body 20 is opened to the outside of the support part 14 below the lower partition wall 14c. 20b, and forms an injection water supply passage 18 that extends from this opening 20b through the pipe body 20 and the upper chamber 21 to the injection ports 16, 16, . In addition, the support part 14
, the peripheral wall of the support part 14 and the upper and lower partition walls 14
An opening 22a is provided which communicates with an annular intermediate chamber 22 surrounded by b, 14c and the peripheral wall of the tube body 20, and from this opening 22a through the interior of the intermediate chamber 22, the jet nozzles 17, 17, . A jet water supply passage 19 is formed.

Further, each of the supply passages 18 and 19 is connected to a water supply conduit 23 and 24 each equipped with a flow rate adjustment means such as a pump or a flow rate adjustment valve, so that the amount of water sent to each supply passage 18 and 19 can be adjusted. It can be adjusted to increase or decrease separately. In addition, each water supply channel 23, 24
may be derived from separate water supply systems or may be branched from the same water supply system.

The outer box 13 is made of a shiny metal material such as stainless steel and is formed into a square cylindrical shape.
It has a square columnar outer circumferential surface 13a with a mirror surface, and is rotatably supported by the support 12 in the following manner so as to surround the outer circumferential surface.

That is, at the center of the upper part of the outer box 13, a rotation center body 25 having a concave portion 25a opening downward is connected via a plurality of support rods 26, 26, . . . At the lower end of the outer box 13, a plurality of guide rods 27, 27, . On the other hand, a placing part 29 on which a sphere 28 is placed and supported is protruded from the center of the upper wall 14a of the supporting part 14 of the supporting body 12, and an annular rail is provided on the peripheral wall of the supporting part 14. A body 30 is fixed. The outer box 13 is inserted into the support 12 from above, and the recess 25a of the rotation center body 25 is received and supported by the sphere 28 on the upper wall 14a of the support 14, and each guide Sphere 27a of rod 27
By slidingly contacting the rail body 30 of the support part 14, the outer box 13 is supported rotatably around the axis of the support body 12.

In addition, the inner peripheral surface 13b of the outer box 13 and the rotation center body 2
A plurality of wire meshes 31 and 32 are provided on the outer circumferential surface of 5 to cover the upper side of the injection ports 16, 16... in a multilayered manner.
32... is installed. Further, a V ring 33 is provided between the outer box 13 and the jet water guide portion 15 of the support body 12 for sealing between both 13 and 15.
is interposed. This V ring 33 is fitted on the upper part of the water jet guide part 15, and the inner circumferential surface 1 of the outer box 13
It is in sliding contact with a V-ring receiver 34 protruding from 3b.

According to the water fountain device configured as described above, when water is fed from each water supply channel 23, 24 to each supply channel 18, 19, water flows upward from the injection ports 16, 16... communicating with the injection water supply channel 18. At the same time as water is jetted, water is jetted toward the inner circumferential surface 13b of the outer box 13 from the jetting nozzles 17, 17, .

Therefore, the jet water jetted from the jet ports 16, 16, ... passes through the wire meshes 32, 32, ..., and 31, and then follows a falling path that surrounds the outer circumferential surface 13a of the outer box 13. As a result, a curtain-like fountain surrounding the outer peripheral surface 13a of the outer box 13 is formed. At this time, the jetted water flows through the multi-layer wire mesh 32,
32... and 31, it is uniformly dispersed, so that an extremely fine and beautiful curtain-like fountain is formed.

Furthermore, the water jetted from each jetting nozzle 17 collides with the inner circumferential surface 13b of the outer box 13, so that the outer box 13 is rotated counterclockwise in FIG. At this time, the outer box 13 and the support 12
Since the space between the water jet guide portion 15 and the water jet guide portion 15 is sealed by the V ring 33, the water jetted from the jet nozzle 16 passes between the two 13 and 15 and flows between the outer box 13 and the support portion 14. This prevents an unexpected situation in which the water flows in and thereby prevents the rotation of the outer box 13 by the water jetted from the jet nozzle 17.

In this way, a curtain-shaped fountain surrounding the outer circumferential surface 13a of the outer box 13 is formed by the water jetted from the injection ports 16, 16... Since the box 13 is rotated by the jet nozzles 17, 17, . . . , a fountain shape is formed that gives a beautiful impression to the viewer.

By individually increasing or decreasing the amount of water sent to each supply passage 18, 19, the shape of the jetted water and the rotation of the outer box 13 due to the jetted water can be changed individually. The form of the fountain can be freely changed and diversified, and an extremely wide variety of fountain effects can be produced.
