Abstract

PURPOSE:To provide a titled device with simple construction and gives an aesthetic sense through rotation of an outside box by injecting pressure water from the top end of an inside cylinder erected in a water tank in an upward direction with respect to a guide and turning the outside box enclosing the inside pipe with the water injected in a horizontal direction. CONSTITUTION:Pressure water is injected upward from an injection port 2 at the top end of an inside cylinder 1 which is erected in a water tank and communicates with a pump, and a fountain is formed by the conical guide 3 mounted to a cover body 12 bolted 11 to the cylinder 1. An outside box 5 which is freely turnable in a circumferential direction is provided so as to enclose the cylinder 1. Nozzles 4 which inject the pressure water horizontally are provided on the circumferential surface of the cylinder 1, and a plate-like water receiver 6 is provided in the box 5 in the position facing the nozzles to receive the water injected from the nozzles 4 thereby rotating the box 5. The box 5 consists of a stainless steel or the like mounted to a body 9 for mounting the outside box, and when the box is rotated, the fountain which gives an aesthetic impression to the viewer is obtained.

Description

[Detailed description of the invention] The present invention relates to a fountain device having a rotating outer box.

Conventionally, there is a fountain device that has an outer box that surrounds an inner cylinder that sprays water from the top and rotates in one direction, but such fountain devices rotate the outer box using a drive source such as an electric motor. Because of this, the rotation mechanism is complicated. In other words, electric motors,
A transmission mechanism that converts the driving force of this electric motor into rotation of the outer box, a power supply to the electric motor, etc. are required, and these items must be sealed against water to rotate the outer box. The disadvantage is that the device inevitably becomes complicated. Moreover, this drawback causes the problem that maintenance and inspection are time-consuming. Furthermore, even if an attempt is made to create a fountain by installing a large number of such fountain devices, the current situation is that the devices become too large to be realized.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to rotate the outer box with a simple structure without using an electric motor or the like, thereby giving a beautiful impression to the viewer. To provide a fountain device having a rotating outer box that can rotate.

In order to achieve the above object 1, the present invention is characterized by the following configuration. That is, in the present invention, an inner cylinder is provided with a guide at the tip that scatters upwardly directed water from the injection port downward, and an outer cylinder is installed upright in a water tank and is rotatable and surrounds the inner cylinder. In a water fountain device equipped with a box, the outer box was conventionally rotated by the driving force of an electric motor, etc., but now an injection nozzle is installed on the side of the inner cylinder to eject pressurized water from inside the inner cylinder. Opposing water receiving blades are provided inside the outer box, and the pressure water from the injection nozzle is sprayed onto the water receiving blades in the outer box to rotate the outer box, making the configuration of the fountain device simple and yet useful for fountains. This makes it possible to use water effectively.

An embodiment of the present invention will be described below with reference to the drawings.

1 in the figure is an inner cylinder. This inner cylinder 1 is erected at the bottom of the water tank, and the inside thereof is communicated with a pump (not shown) so that pressurized water can be supplied. Moreover, the - of this inner cylinder 1
A spout 2 is provided at the L end, and the pressure water inside the inner cylinder 1 is spouted in one direction. This spout 2
At the top, an umbrella-shaped guide 3 with the hemispherical surface of the bowl facing downward is fixed to the tip of the inner cylinder 1. By providing this guide 3, the pressure water jetted from the spout 2 is scattered around the outer circumference of the inner cylinder 1.

Further, on the circumferential surface 1a of the inner cylinder 1, an appropriate number of (
In this example, four jet nozzles 4 are provided, and the jet nozzles 4, which horizontally jet the pressurized water in the inner cylinder 1, are divided into predetermined layers (two layers in this example). Plate-shaped water receiving blades 6 are fixed on the inner surface of the outer box 5 corresponding to the injection nozzles 4 of each layer, so that water can be sprayed from the injection nozzles 4. ing.

Further, an annular ring body 7 is fixed to the layer of the inner cylinder 1 where the injection nozzle 4 is not provided, and an annular bush 8 is attached to the outer box 5 corresponding to this layer from the inside. . . , an outer box attachment body 9 .

The outer box 5 is formed by attaching a shiny plate such as a stainless steel plate to an outer case mounting body 9, and in this embodiment, the cross-sectional shape is square. Further, at the lower end of the lowermost bushing 8, there is a collar portion 8 that comes into sliding contact with the support member 10 of the inner cylinder 1.
A is provided at the upper end of the uppermost bushing 8, and a boxwood portion 8b is provided which slides into contact with the lid 12 provided on the inner cylinder 1 via the port 1. is held rotatably. Note that the guide 3 is connected to the lid body]2.
It is fixedly installed. In the figure, 13... is the water receiving blade 6.
This is a continuous tree passageway that allows water from the spray nozzles 4... to fall into the water tank.

With this configuration, the water will be ejected from the pressure water drain in the inner cylinder 1, the injection port 2, and each injection nozzle 4, and the water ejected from the injection port 2 will flow through the guide 3. It becomes a fountain that scatters around the outer periphery of the outer box 5, and each injection nozzle 4
The water injected from... is sent to the water receiving blades 6 of the outer box 5...
At this time, the outer box 5 will be rotated.

At this time, the water that hits the water receiving blades 6...
3 and flows into the aquarium.

In this way, a fountain can be formed while rotating the outer box 5 with a simple configuration, and the outer box 5 can be constantly rotated to give beauty to the viewer. Furthermore, since the pressure water in the inner cylinder 1 is used as a fountain and a rotation source for the outer box 5, water in the water tank can be used effectively. Since the outer box 5 can be rotated with such a simple configuration, it is possible to easily manufacture a fountain facility in which a large number of such fountain devices are installed in a water tank.

In the above embodiments, the outer box 5 has a square cross-sectional shape, but the present invention is not limited to this. Alternatively, the outer box may be provided with grooves so that the viewer can feel the change.

Further, although the outer box 5 has been described as being made of a glossy member such as stainless steel, the present invention is not limited thereto, and a mirror may be attached to the outer box 5.

As explained above, the fountain device having a rotating outer box of the present invention has an inner cylinder communicating with the pump, an injection port provided at the upper end of the inner cylinder, and an injection port arranged to face the injection port. A guide provided therein, an injection nozzle provided on a side peripheral surface of the inner cylinder, and a water receiving blade that surrounds the inner cylinder and is rotatably supported in the circumferential direction and faces the injection nozzle on the inner surface. Since it is equipped with an outer box, the water jetted from the injection port is scattered around the outer periphery of the outer box via the guide, and the water jetted from the injection nozzle is sprayed onto the water receiving blades of the outer box. The outer box can be rotated. As a result, the fountain device of the present invention can rotate the outer box with a simple structure that does not use an electric motor or the like, and can give a beautiful impression to the viewer.
