The invention according to claim 4 is characterized in that the amount of water supplied by the water supply device is increased or decreased according to the amount of sunlight.

[0005]

As described above, according to the first aspect of the present invention, the stepped flow path formed by artificial stone is inclined forward and downward, so that the flat portion of the stair is eliminated, and the waterfall starts from the top of the stair. As the water falls vertically on the slope of the step, the waterfall flow path is shortened and the stagnation of water on the flat part is eliminated, so that the waterfall with a smaller amount of water and the splash of water can be displayed vertically. it can. According to the second aspect of the present invention, the step-shaped channel is formed into a square artificial stone formed by a flat surface in a fitting groove provided in a lowermost step of a fixing guide having a stepped portion inclined forward and downward. After fitting, the artificial stone of the second step is fitted in the gap between the artificial stone and the upper stairs, and the artificial stone is formed by sequentially stacking the artificial stones from the lowermost to the uppermost step, so that the lowermost fitting groove is formed. Since the artificial stone fitted to the supporting stone has a predetermined angle to support the artificial stone of the second or higher stage, the artificial stone does not drop due to a change in temperature or a change with time. According to the third aspect of the present invention, since the electric power obtained from the sunlight is used as the driving source, it is possible to suppress the energy consumption of the commercial power supply and to use the power supply regardless of the installation location of the driving power supply.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the drawings. In FIG. 1, an artificial stone fixing guide 3 (hereinafter simply referred to as a fixing guide) constituting a flow path of a waterfall is fixed to a bottom 2a of a water storage tank 2 for storing waterfall water. The portion of the fixing guide 3 that forms the flow path of the waterfall is formed in a stepped shape that is inclined forward and downward by an angle α, and a fitting groove 3a for fitting the artificial stone 4 is formed at the bottom. ing. The artificial stone 4 formed by a flat surface is fitted in the fitting groove 3a, and forms the first step of the stepped flow path 1a. The depth of the fitting groove 3a is formed to be approximately half the height of the artificial stone 4 to be fitted. The artificial stone 4 is further fitted into the gap between the first-stage artificial stone 4 and the upper step 3b to form a second step. The artificial stones 4 are sequentially stacked up to the top by the same method. Note that only the falling surface 4a of the artificial stone 4 does not have to be a flat surface, and the surface with irregularities has more drops of water that falls, and can better show the scenery of the waterfall.

At the top of the fixing guide 3, a waterfall 5 is formed by stacking artificial stones 4 and serves as a start of the waterfall. The waterfall 5 is connected to the water tank 2 through a water supply channel 6, and an outlet 7 a of an electric pump 7 penetrates the water supply channel 6. The electric pump 7 is fixed to the fixing guide 3 so that the water in the water storage tank 2 that has flowed down can be supplied to the waterfall tank 5 by the water conduit 3e. The electric pump 7 is connected to the controller 9 via a power cord 7b.
A drain port 2b is provided in the upper part of the water storage tank 2. Outside the water storage tank 2, a solar cell panel 10 is fixed integrally with the water storage tank 2 by a support base 10a. In addition, the solar cell panel 10 may be configured separately from the water storage tank 2,
Further, it may be fixed to the back surface 3c of the fixing guide 3 at a predetermined angle that easily receives sunlight. Solar panel 1
The output line 10b of 0 passes through the wiring path 2c and is wired to the controller 9 and connected to the storage battery 8. Wirings 9a and 9b branched from the controller 9 are connected to an operation panel 11 and an illumination lamp 12 provided at a front portion of the water storage tank. The storage battery 8 and the control panel 9 are covered by a waterproof panel 13.

Next, the operation of the embodiment of the present invention will be described in detail. In FIG. 1, water stored in a water storage tank 2 is sent to a waterfall 5 through a water supply passage 6 by an electric pump 7 through a water supply passage 3e. When the waterfall 5 is filled, the water flows down the stepped flow path 1a, is stored again in the water storage tank 2, and is circulated repeatedly. Stepwise flow path 1a of the present invention
As shown in FIG. 2 (b), since water 15 is inclined downward and forward by an angle α, the water 15 falls vertically from the vertex 1b of the stepped flow path 1a to the next step, so that a + b> c. , FIG. 2
The flow path is shorter than the conventional non-inclined stepped flow path 100a shown in (a), and since there is no flat portion 100b, there is no stagnation of the flow, and when it falls vertically, the droplet 14 hits the next stage and rises. Therefore, the waterfall can be displayed with a smaller amount of water than before. In addition, the inclination angle α is appropriately selected according to the degree of rise of the droplets 14 so that the waterfall can be displayed best. Excess water in the water storage tank 2 is drained from a drain port 2b.

The electric power generated by the solar cell panel 10 is stored in the storage battery 8 via the output line 10b and the controller 9. The electric pump 7 is driven by operating the controller 9 by a switch (not shown) provided on the operation panel 11 and supplying the electric power stored in the storage battery 8. If the power stored in the storage battery 8 alone is insufficient, a commercial power supply (not shown) may be used together. FIG. 3 is a flowchart of the control unit for controlling the drive of the electric pump 7. FIG. 3A is a flowchart of the main routine. When the water circulation switch of the artificial waterfall is turned on in step (hereinafter simply referred to as S) 101, the calculation of the sunlight correction voltage Vm is performed in S102. The calculation of the sunlight correction voltage Vm will be described later. In S103, S10
Based on the Vm value calculated in 2, the setting of the drive voltage V of the electric pump 7 is performed by the equation V = a × Vm + b. Here, a and b are default values, a is a conversion coefficient for increasing / decreasing the drive voltage by the solar correction voltage, and b is a supply of water necessary to generate a waterfall flow regardless of the intensity of the sun. This is the minimum drive voltage of the electric pump 7 that is enabled.

Next, at S104, the electric pump 7 is driven by the drive voltage V obtained at S103. S105
In step S106, it is read whether or not the water circulation switch of the artificial waterfall is set to the OFF signal.
The presence or absence of the FF signal is determined. If there is no FF signal, the calculation of the sunlight correction voltage Vm in S102 is performed, and the following is repeated. If there is, the energization of the electric pump 7 is stopped, and the main routine ends.

Next, a subroutine for calculating the sunlight correction voltage Vm will be described in detail with reference to FIG. When the calculation signal of the sunlight correction voltage Vm is input in S200, the reading of the solar cell panel generated voltage Vn is performed in S201. Here, Vn records the generated voltages of the solar cell panels as V1, V2,... Vn in n data memories. In S202, the oldest voltage data is deleted and the latest data is stored and updated each time the calculation signal of the sunlight correction voltage Vm in S102 is input. S203
In, the calculation of the sunlight correction voltage Vm based on the average value of the voltage data is performed by the equation Vm = ΣVn / n, and the subroutine ends. That is, Vm is obtained as an average value of the voltage data stored in the n data memories. In this manner, the electric pump 7 has a drive voltage that increases or decreases in accordance with the intensity of the sunlight, thereby controlling the amount of water supply.

[0012]

The present invention has the following effects because it is configured as described above. That is, according to the first aspect of the present invention, the stepped flow path is inclined forward and downward, so that the flow path length of the waterfall is shortened, the flat portion is eliminated, and water stagnation is eliminated. Since the waterfall can be represented by the amount of water, the capacity of the electric pump can be reduced, and the energy consumption can be reduced. According to the second aspect of the present invention, since the artificial stone of the second stage is supported by the artificial stone of the first stage fitted in the fitting groove of the lowermost stage, the artificial stone of the second stage or more may be wet or dry. Artificial stones do not fall due to repetition, temperature changes or changes over time. According to the third aspect of the present invention, since the electric power obtained from the sunlight is used as the driving source, it is possible to suppress the energy consumption of the commercial power supply and to use the power supply regardless of the installation location of the driving power supply. Not limited to Further, in the invention of claim 4, since the amount of water supplied by the water supply device is increased or decreased according to the amount of sunlight, the amount of water supply is increased in the daytime, the generation of water droplets is increased, and Heat can make the area around the artificial waterfall cool, and at night the water supply can be reduced to reduce the sound of water.
