Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification device suitable for purifying water in a small-scale lake pond such as an agricultural water reservoir.

[0002]

2. Description of the Related Art Around 220,000 ponds for agricultural water are provided nationwide. The use of these agricultural ponds as agricultural water has decreased due to the decrease in paddy fields and the like, becoming a closed basin and the flow of water disappears to form a pool. The depth and shape of the bottom of these ponds are indefinite, and the shallow water depth and narrow area make it easy for the water temperature to rise. Furthermore, these unused ponds are in the suburbs of the city, and domestic sewage flows into them, so they are eutrophication. Under these circumstances, the bottoms of these ponds are in a sludge state, and the waste is suspended due to illegal dumping of the waste, causing the occurrence of water-bloom and the like, which is a serious problem for the destruction of the hydrosphere.

As a method for cleaning these reservoirs and the like, it has been attempted to improve the water quality by pumping pond water using a fountain, ejecting it into the air, exposing it to the air and supplying oxygen.
However, when these methods and devices are used for the above-mentioned agricultural water reservoir, etc., the environment of the reservoir is shallow because the bottom of the reservoir is shallow and the periphery of the reservoir is not maintained, so there is no power source such as electric power, sludge and so on. A normal fountain device should be used for reasons such as blue water or floating debris blocking the water supply port, and it is difficult for general people to secure personnel for maintenance because it is prohibited to enter the pond. You are in a difficult situation.

[0004]

In view of these circumstances, the present invention can be used even in a place without a power source such as an electric power source, and can be used even if there is floating dust, water-bloom, sludge, etc. The purpose is to provide. A further object of the present invention is to provide a water purification device that is not fixed at one location and can move on the water surface by itself so as to expand the purification range. Still another object of the present invention is to provide a water purification device that requires less maintenance.

[0005]

In order to achieve the above object, the present invention provides a fountain device of a type that floats on water.
Furthermore, a power source using a solar cell floating on the water surface was used as a power source. Furthermore, the fountain device was stored in a spherical container so that water could be taken in from the bottom.

[0006]

By separating the fountain device and the power source, the degree of freedom of movement of the fountain device is increased, and the capacity of the power source can be changed according to the capacity of the fountain.

Continue driving. The amount of charge in the storage battery begins to decrease as it discharges. Charge / discharge control means 315
Monitors whether or not the discharge time is within a predetermined time, and when the discharge time exceeds the predetermined time T ₂ , the pump operation is stopped and the generated power is used for charging the storage battery.

When the amount of sunshine exceeds a predetermined value (A) and a power generation amount exceeding the power consumption of the pump is obtained, the pump operation is restarted. After that, when the amount of sunlight is reduced to a predetermined value (B) or less and the generated power becomes less than the power consumption of the pump, the insufficient power is supplied from the storage battery. Further, even within the predetermined time T2, the amount of sunshine is reduced to a predetermined value (C).
If the following occurs and the storage battery cannot be charged, the pump operation is stopped.

In the above example, the operation of the pump is controlled based on the amount of sunlight (the amount of power generation), but the operation of the pump can be controlled by detecting the charge amount of the storage battery.

Further, during cloudy weather, the pump can be intermittently operated by the electric power from the storage battery. Alternatively, one of the pumps may be selected to operate with reduced power consumption.
