It is equipped with a control means for outputting a signal for performing selective opening/closing control.

Further, a second aspect of the present invention provides a model flying rod holding means for holding a model flying object in a manner that it can be raised and lowered within a projection plane of a fountain pond, a lifting means for raising and lowering the model flying rod holding means, and a lifting means disposed in the fountain pond. A fountain nozzle provided therein, a fountain path for the fountain nozzle that communicates the fountain nozzle with the fountain pond, a pump that is interposed in the fountain path for the fountain nozzle and that spouts water from the fountain nozzle, and operating or stopping the pump. and control means for outputting a signal for selectively controlling the opening and closing of a valve body provided in the fountain path for the fountain nozzle.

(Function) According to the above configuration, the model flying object is raised from the water surface level of the fountain pond or from underwater by operating the lifting means and raising the model flying rod holding means.

It can be lifted up with the atmosphere of a launch.

In this case, water is jetted from the downward facing fountain nozzle of the model flying object to create an atmosphere similar to that of the launch fuel injection of the model flying object.

Additionally, a sea of clouds can be created by jetting water from the fountain nozzles installed in the fountain pond.

Further, by lowering the model flying rod holding means, it is possible to lower the model flying object with an atmosphere that causes it to make a soft landing on the water surface level. In this case, water is jetted from the downward facing fountain nozzle to create an atmosphere in which fuel is injected backwards.

The opening/closing operation of the valve body v2 interposed in the reflux path 12 that communicates the lowermost outer cylinder 2A of the model flying rod holding means 2 and the fountain pond 1O are controlled by electrical signals output from the control means 8. This is done by a signal. therefore,
Each of the valve bodies v1 to v4 employs a solenoid valve or an electric valve that can secure an intermediate opening degree.

A lighting fixture 13 is attached to the ceiling of the model flying object 1, and is turned on or on and off according to an electrical signal output from the control means 8, and its light is irradiated to the outside through a plurality of windows IA.

A floodlight 14 and a speaker 15 are installed around the fountain pond lO.
etc. are appropriately arranged, and emit light and emit sound in response to electrical signals output from the control means 8.

Next, the operation of the above configuration will be explained.

By turning on a start switch (not shown) provided in the control means 8, the pump 7 is started and the valve body V
l, V3. V4 is opened and valve body V2 is closed.

When the pump 7 starts operating, the water in the fountain pond 1O is forced to be sent to the hollow part 2B of the model flying rod holding means 2 through the lifting means 3 and the passage of the downward fountain nozzle fountain path 5. is gradually extended to raise the model flying object l, and as described above, since the hollow portion 2B communicates with the downward fountain nozzle 9, water is jetted from the downward fountain nozzle 9. For the downward facing fountain nozzle 8.

By having an air bleed facing the main nozzle, it is possible to eject a cloudy mist-like air-mixed water stream, and therefore, the model flying object l is attached to the supporting means 11 provided at the water surface level of the fountain pond lO. It is possible to ascend with the atmosphere of launching from the launch pad, that is, the atmosphere of fuel injection at the time of rocket launch, and moreover, the model flying rod holding means 2 is hidden from the beginning, so that the model flying object l is raised by its own blade. A state like this appears.

In addition, the fountain nozzles 4A and 4 provided in the first and second passages 11tA and 8B constituting the fountain path 8 for fountain nozzles
Water is jetted diagonally and upwards from B, creating a sea of clouds.

Since it is technically easy to color the water jetted from the fountain nozzles 4A, 48.9, the -layer and its atmosphere can be removed by jetting the desired colored water. Of course, during the ascent process of the model flying object 1, the lighting equipment 3 is turned on or blinks, and the floodlight 1 is turned on or off.
4, the model flying object l is irradiated, and operations such as emitting sound from the speaker 15 are optionally performed by electrical signals output from the control means 8.

By continuing the above-mentioned operation, as shown in the figure, when the model flying stick holding means 2 is extended to the maximum flame and the model flying object 1 has reached the upper limit position, the electric power output from the control means 8 is In response to the signal, the flow rate is controlled so that the model flying rod holding means 2 is maintained in the illustrated state in which it is extended to the maximum flame, and a jet of water is ensured from the downward fountain nozzle 8. This flow rate control is performed by selecting the model of the motor that drives the pump 7 and the model of the valve body Vl and combining the two.

And, this combination is ■ constant speed motor and electric valve,
■Variable speed motor and solenoid valve, ■Variable speed motor and electric valve, ■Constant speed motor and solenoid valve, etc. are used.

After a predetermined period of time has elapsed, a signal is output from the control means 8 to open the valve body v2 interposed in the reflux path 12.

Thereby, the water in the hollow portion 2B of the model flying rod holding means 2 is returned to the fountain pond 10 through the return flow path 12.

Therefore, by setting the opening degree of the valve body v2, that is, the passage cross section of the reflux passage 12 to a predetermined value, water can be jetted from the downward fountain nozzle 9 while the model flying object
The model flying rod holding means 2 can be shortened so as to gradually lower the model flying rod. When the model flying rod holding means 2 is shortened to the shortest length, the model flying object 1 is mounted and supported on the supporting means 11.

In this case, the jet of water from the downward fountain nozzle 9 creates an atmosphere in which fuel is injected backwards in order to cause the model flying object 1 to land softly on the water surface.

When the model flying object 1 reaches the lower limit position and is placed and supported on the support means 11, the stop switch provided in the control means 8 is turned on, or the model flying object 1 is placed on the support means 11. When the placed and supported state is detected, the pump 7 is stopped by an electrical signal output from the control means 8, and the valve bodies Vl, V2 . V3. V4 closes and prepares for the next operation.

After the start switch is turned on, the above operation is repeated.

The passage 33 has a valve body V5. VB is interposed. For this purpose, the model flying rod holding means 3 is configured to be extendable and airtight. The fountain path 5 for the downward fountain nozzle is connected to a flexible passage (flexible tube) 5A that communicates with the downward fountain nozzle 9 through the hollow portion 2B of the model flying rod holding means 2. Therefore, in order to extend the model flying rod holding means 2 and raise the model flying object 1, the near compressor 31 is operated in advance by an electrical signal output from the control means 8, and compressed air is stored in the 7-cumulator 32. Then, by opening the valve body v5 and closing the valve body V6, compressed air is supplied from the first passage 33 into the hollow part 2B of the model flying rod holding means 2. In this case, the flexible passage 5A in the downward fountain nozzle fountain path 5 expands according to the degree of expansion of the model flying rod holding means 2, and the pump 7
