Description

[Detailed Description of the Invention] Industrial Fields of Use This fountain bridge mainly relates to a bridge built over an artificial lake, with fountains gushing out from one side of the bridge to create a water arch so that people can walk under it.

BACKGROUND TECHNOLOGY Usually, a bridge is a bridge built over a river, lake, strait, lowland, etc. by creating a space below it for a road.
It is considered to be a structure built for the passage of railways, etc., and is categorized by its structural type, such as girder bridges, truss bridges, arch bridges, and movable bridges.

Problems that the invention aims to solve However, all of the above-mentioned bridges are built over rivers or roads, and none of them are submerged in water. Lose.

This idea was created in view of the existing problems, and its purpose was to make the submerged bridge appear in the atmosphere by the operation of the pump, and at the same time make it possible to pass through.
The objective is to provide a fountain bridge where one can see the beauty of waterfalls on both sides of the bridge and the dynamic beauty of the fountain arch.

Means for Solving the Problems In order to achieve the above object, the fountain bridge of the present invention has a side plate that is movable up and down on the upper part of the side wall, and a bridge in which side gutters are formed on both sides of the sidewalk. , a discharge pump for discharging water in the bridge through the side gutter, and a jet pump for forming a fountain arch from a plurality of fountain nozzles arranged in series at an appropriate distance on one side of the bridge. Consisting of

Furthermore, it is more effective to provide water level adjustment pipes below the bridge to adjust the water level on both sides of the bridge.

Furthermore, by providing a plurality of lighting devices at appropriate intervals near the fountain nozzle and the fountain's water landing position, a beautiful and fantastical beauty is created.

Function In a fountain bridge constructed as described above, for example, the bridge is built over a part of an artificial lake, the bridge is initially submerged in water, and when the fountain pump is activated by a push button, the water level inside the bridge is lowered and the sidewalk is exposed. At the same time, the fountain pump operates and the fountain nozzle forms a fountain arch, under which people can pass.

In addition, water cascades down the side walls of the bridge, and at night it can be illuminated with colorful lights.

In this way, the dynamic beauty of the fountain arches and waterfalls arouses the interest of visitors, and especially at night, the fountains are illuminated with colorful lights, creating a fantastical beauty and a refreshing atmosphere at the same time. This product solves the problems of the conventional products, such as giving a pleasant impression and not damaging the surrounding scenery.

Embodiments Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 is a perspective view of a fountain bridge according to a first embodiment of this invention, and FIG. 2 is a front view in longitudinal section of a portion of the side plate.

1 is the fountain bridge.

2 is a bridge submerged in an artificial lake, with side walls 2
Slide plate 2 is placed on top of a and 2a to move up and down.
Angle 2a formed by screwing a11 and a tightening bolt
Side plates 2a1, 2a1 consisting of 12 are provided, and side grooves 2c, 2c are formed on both sides of the sidewalk 2b.

3 drains the water in the sidewalk 2b to the side gutters 2c, 2c.
A discharge pipe 3 is used to discharge the accumulated water that flows into the tank 4 through the tank 4 to the outside (in this example, the artificial lake).
This is a lower discharge pump with a protruding part.

Reference numeral 5 denotes a fountain pump having a plurality of fountain nozzles 5a protruding from one side of the bridge 2 at an appropriate distance, and similar to the discharge pump 3, the tank 4
It is configured to drain the water inside.

6 is a fountain pressure regulating valve, which is provided to correspond to the size of the arch.

A float switch 7 controls the drain pump 3 according to the water level in the tank 4.

The operating state of the fountain bridge 1 configured as described above will be described below.

As shown in FIGS. 3 and 4, first, the side plate 2a
The top of slide plate 2a11 in 1 is several times above the water surface.
Adjust so that it is positioned below cm.

After that, turn the start button "ON", activate the drainage pump 3, and drain the water inside the bridge 2 into the gutters 2c, 2c.
The accumulated water that flows into the tank 4 through the tank 4 is discharged to the artificial lake through the discharge pipe 3a, thereby drying the inside of the bridge 2.

Subsequently, the float switch 7 is activated, and the inverter controls the rotational speed of the discharge pump 3, so that the water level in the tank 4 is maintained at an appropriate level with slight ups and downs, and the bridge 2 is always open for traffic.

At this time, water flows down from the side walls 2a, 2a of the bridge 2 into the side gutters 2c, 2c like a waterfall.

At the same time, the fountain pump 5 operates, and the fountain nozzles a form a fountain arch A under which people can pass.

When stopping, turn on the stop button, sound the buzzer to notify the surrounding area, stop the fountain pump 5 and drain pump 3, and submerge the bridge 2.

FIG. 5 is a perspective view of the main parts of a fountain bridge according to a second embodiment of this invention.

This fountain bridge 21 has water level adjustment pipes 8, 8, which are cylindrical pipes bent upward at both ends, arranged in parallel below the bridge 22 in order to adjust the water level on both sides of the bridge 22.

This fountain bridge 21 is used in a place where the water on both sides of the bridge 22 is completely separated.

In the above embodiment, multicolored lighting devices may be provided at appropriate intervals in the vicinity of the fountain nozzle and the fountain's water landing position.

Effects of the invention Since this invention is configured as described above, it produces the following effects.

1 First of all, in the first embodiment, the conventional concept of a bridge is broken, and a bridge submerged in water emerges into the atmosphere by the operation of a discharge pump and becomes passable, and at the same time waterfalls are created on both sides of the bridge. It has various excellent effects, such as the beauty of the flowing water and the dynamic beauty of the fountain arch created by the fountain pump, as well as providing a refreshing feeling and not disturbing the surrounding scenery.

2 The second embodiment is also effective in adjusting the water level when the water on both sides of the bridge is completely separated.

3 Furthermore, the lighting equipment has the effect of creating a fantastical beauty.
