Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a fountain device, and in particular, it is possible to form a fountain pond by a simple construction method in water transmission system passages, power transmission system passages, drainage system passages, etc. The present invention relates to a fountain device in which a box is disposed between a fountain water supply source or driving power supply source as a power supply medium device and a fountain pond, and the box can be used for multiple purposes.

(Conventional technology) The fountain pond of a fountain device has a water supply passage to compensate for a drop in water level due to water scattering or natural evaporation, an overflow passage to keep the water level constant, and a water passage used to drain water during maintenance inspections, etc. A power transmission system path is provided for passing a cable that supplies power to a circulation pump and a submersible motor for driving a fountain pump.

By the way, the fountain pond is generally constructed on-site.
That is, it is constructed by assembling formwork on site and pouring concrete into the assembled formwork. Therefore, each of the passages will also be formed when constructing the fountain pond. In other words, as shown in FIGS. 5 to 7, with respect to the upright peripheral wall B of the fountain pond A, the vertical wall opens inside the fountain A at the upper part of the upright peripheral wall B and opens to the outside of the fountain A at the lower part. A plurality of passages D are formed, and these vertical passages D
is utilized as an overflow passage D ₁ and a power transmission system passage D ₂ , and in particular, a cable or a conduit pipe with a cable inserted therein is inserted into the power transmission system passage D ₂ , and an opening is made on the upper surface of the bottom wall F of the fountain pond A, and the fountain pond is Drain passage G that opens to the outside of A (see Figure 8)
is formed.

(Problem to be solved by the invention) However, in the conventional fountain pond, the shape of each passage D is complicated, and when forming passages with this complicated shape, it is difficult to form the passages in the formwork. It is necessary to do some work, which is a factor that reduces the workability of constructing fountain pond A.

On the other hand, in recent years, when various events are held in various places, there has been an increasing desire to install fountain pond A only during the relatively short event period of 3 to 12 months.

However, fountain pond A, which is constructed using the conventional cast-in-place construction method, is economically disadvantageous due to the high construction cost.In addition, when it is dismantled and removed at the end of the event, it requires the removal of reinforced concrete, etc., and the remaining materials. This requires complicated post-processing such as disposal, which naturally increases removal costs. Therefore, with conventional fountain ponds, the depreciation cost per unit time is high, and when installing a fountain pond, there is a problem that the installation cannot be avoided due to economic constraints.

Therefore, the fountain pond can be easily constructed, dismantled and removed, and is economically advantageous.The fountain pond can be constructed from an aggregate of multiple blocks joined together on site, and can be dismantled and removed by disassembling these blocks. A possible structure is as follows.

However, in such a fountain pond A, it is necessary to use a common mold for molding each block with concrete, so a block molding mold having a passage D having the structure described in the conventional example, At least two types of block molding molds without passages D must be prepared, and these molds are extremely expensive, resulting in an economically disadvantageous problem.

Each block is molded in a factory and then transported to the fountain pond construction site. However, in the passage structure described in the conventional example, the wall thickness around the passage portion becomes extremely thin, resulting in a decrease in wall rigidity. Therefore, there is a risk that the blocks forming the passages will be damaged due to vibrations and shocks applied during transportation and construction.

Furthermore, in the passages D... having the above configuration, the cable is exposed particularly at the upper inner periphery of the power transmission system passage _D2 , degrading the appearance. Therefore, this exposed portion must be hidden with a cover, which poses problems such as extra effort required during construction.

The present invention was developed in view of the above circumstances, and it is possible to easily form each passage for the water transmission system, power transmission system, drainage system, etc., and it can also be used as a water and power supply medium device for fountain water supply and driving power supply. It is an object of the present invention to provide a fountain device configured so that a box placed between a water source and a fountain pond can be used for multiple purposes.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides that at least one water supply system passage, one power transmission system passage, and one drainage system passage are respectively formed through the wall of the fountain pond. A box housing an overflow mechanism for determining the reference water level of the fountain pond and a power transmission line connection mechanism is disposed around the fountain pond, and the inside of the box and the fountain pond are connected via the water transmission system passage and the power transmission system passage. While communicating with each other,
A water supply system passage and a power supply system wiring are connected to the box, and an overflow system passage is led out from the box.

(Function) In the present invention, each passage can be formed by a pipe that penetrates the wall of the fountain pond, so when constructing a fountain basin by casting on site, there is no need to perform complicated work on the formwork to form passages. There is no. In other words, it is sufficient to attach the passage forming pipe to the formwork.
In addition, in a fountain pond constructed from an aggregate of a plurality of blocks joined together, a block with passages can be molded by attaching passage forming pipes to the block molding die and performing insert molding. When molding a block without a passageway, it is possible to use a common mold.

Furthermore, a box is placed between the fountain water supply source or driving power supply source and the fountain pond as a water and power supply medium device, and water and power can be supplied through this box, and the water level can be maintained at a constant level. The box itself can be used as a bench or flowerbed.

At the same time, the water supply system passage and power supply system wiring are connected to the box, and the overflow system passage is led out from the box, so that the water level of the fountain pond does not drop due to water scattering or natural evaporation. Of course, it is possible to secure a water supply function to supplement the water level, an overflow function to maintain a constant water level, a drainage function for maintenance and inspection, and a power transmission function to supply power to the circulation pump and fountain pump drive motor. , water supply system passages, power transmission system passages, drainage system passages, etc., which are necessary to exhibit these functions, can be formed using extremely simple construction methods.

Therefore, when molding blocks having passages and blocks having no passages in a fountain pond constructed from an aggregate of a plurality of blocks integrally connected, it is possible to use a common molding die. Furthermore, since the rigidity of the wall portion of the block forming the passage does not decrease, there is no risk of damage due to vibrations or shocks applied during transportation or construction.
In addition, each passage can be formed by a simple construction method even in a fountain pond constructed by casting on-site. Since the cables are not exposed at all in the fountain pond that is constructed, the appearance is improved and the safety level is also increased.

Furthermore, since the box itself can be used as a bench or a flower bed, the box can be used for multiple purposes, and the appearance of the surrounding area of the fountain pond can be improved.
