[Problems to be solved by the device]

One problem is that the construction is specialized and large-scale, so the cost is high, and a considerable construction space is required. Therefore, it is difficult for the common people to easily create a fountain under the housing circumstances where the garden is becoming smaller and smaller, as is the case today.

Another problem is that once a fountain is created, it cannot be moved to another location without being demolished and rebuilt. Therefore, if you do not carefully plan the garden exterior from the beginning and decide where to create the fountain, you will be in trouble if the plan is changed on the way.

Yet another problem is that the layman cannot perform sufficient maintenance, so he is forced to entrust it to a specialist. Therefore, maintenance costs are high and it is uneconomical.

The present invention has been made in view of the above problems, and the purpose thereof is that anyone can easily assemble it at a desired place even if the garden is small, and disassemble and reassemble at another place. Therefore, it is an object of the present invention to provide a prefabricated fountain device which can be freely moved to another place, is easy to maintain and is economically advantageous.

[Means for solving the problem]

In order to achieve the above-mentioned object, the prefabricated fountain device of the present invention has a water pump installed inside a water tank having a drainage port with a valve, and a lid having a nozzle insertion hole and a water drop hole is covered on the water tank. It is characterized in that a fountain nozzle connected to a water pump is inserted into the nozzle insertion hole to project from the upper surface of the lid.

[Action]

The prefabricated fountain device of the present invention is a unit product including a water tank, a lid, a water pump, and a fountain nozzle as essential components, and the water pump is installed inside the water tank at a desired place such as a garden. At the same time, anyone can easily assemble it by simply connecting the fountain nozzle to the water feed pump, covering the water tank with the fountain nozzle, and projecting the fountain nozzle from the nozzle insertion hole to the upper surface of the lid.

Then, when water is injected into the water tank of the fountain device assembled in this way from the water drop hole of the lid and the water pump is operated, the water in the water tank is jetted from the tip of the fountain nozzle by the water pump, and the jetted water is It circulates by flowing into the water tank from the water drop hole of the lid. Therefore, the fountain will not be interrupted unless the water pump is stopped.

On the other hand, when there is a risk that the water in the aquarium will freeze, such as in winter, or when you want to stop the operation of the fountain device for a certain period of time, connect a hose to the valved drain port of the aquarium and open the valve to open the inside of the aquarium. Drain the water. When the water tank is emptied in this way, water does not freeze, a baffler is not generated, and algae do not propagate, so that a pump failure can be prevented and the fountain device can be kept hygienic.
