FIG. 3 is a sectional view taken along line 3-3 of the power generation mechanism 30 shown in FIG. 4, and FIG. 4 is a sectional view taken along line 4-4 of the power generation mechanism 30 shown in FIG. As shown in the figure, the power generation mechanism 30 rotates the impeller housing 31 that is integrated with the connecting pipe 5, the impeller 32 that is rotatably mounted in the impeller housing 31, and the impeller 32. A rotating shaft 34 transmitted to the outside of the housing 31 and a generator 35 that generates power based on the rotation transmitted by the rotating shaft 34 are provided. Although not shown, a through hole into which the rotating shaft 34 can be inserted is formed on the wall surface of the impeller housing 31 on the generator 35 side, and the rotating shaft 34 is used for the impeller in the through hole.

According to the pest repellent device of the embodiment described above, the LED21 is made to emit light while sprinkling water by arranging it on the green of a golf course at night and supplying pressure water, and pests such as ingots and mice. Can be intimidated and repelled. Since this pest repellent device can be easily placed not only on a golf course but also in a place where water is sprinkled by a sprinkler such as a farm or a park, it is possible to intimidate and repel pests.

【0033】

Further, according to the pest repellent device of the embodiment, since the power required for the LED 21 to emit light and the power of the control device 50 are obtained from the battery 40, a power supply voltage such as AC100V is not required. Moreover, since the generator 35 is provided in the connecting pipe 5 and the battery 40 is charged by the electric power generated by the generator 35, the replacement time of the battery 40 can be delayed, and in some cases, the replacement of the battery 40 may not be necessary. it can.

However, a highly directional LED is used and the LED is directed to the outside. By fixing it to the main body 2 of the sprinkler, it is possible to emit light in all directions without providing a reflective mirror.

【0035】

Further, in the pest repellent device of this embodiment, the secondary battery is composed of a nickel-cadmium battery, but the secondary battery that can be charged and discharged is not limited to the nickel-cadmium battery, but is not limited to the nickel-cadmium battery, but is also a nickel-hydrogen storage battery or a lithium secondary battery. It may be any secondary battery such as a battery. Further, in the pest repellent device of this embodiment, a DC motor is used as the generator 35, but a motor having any configuration may be used as long as it can generate power.

【0036】

Furthermore, it is also possible to use a strobe for a camera instead of the LED 21 of the light emitting unit 20 to emit light. Since strobes have stronger light intensity than LEDs, they have a more effective threatening and repelling effect on harmful animals.

【0037】

[Modification 1] In the first embodiment, a configuration using a single LED 21 as a light emitting unit has been described, but a configuration using a plurality of LEDs is also possible. FIG. 6 is a block diagram of a pest repellent device according to this modified example.

The pest repellent device according to this modification is different from the configuration of the first embodiment in that it includes four LEDs 85a, 85b, 85c, 85d and a rotary switch 86. LEDs 85a, 85b, 85c, and 85d are arranged radially outward on the main body 2 of the sprinkler at equal intervals. Further, the rotary switch 86 is arranged between the control device 50 and the slip ring 87. Then, for example, the four internal contacts of the rotary switch 86 are sequentially turned on and off by utilizing the rotational operation of the main body 2 (see FIG. 1) of the sprinkler. As a result, the respective LEDs 85a, 85b, 85c, and 85d can be made to emit light in sequence, and light can be emitted in all directions.

【0039】

By connecting the LEDs 85a, 85b, 85c, and 85d directly to the control device 50 without providing the rotary switch 86, the control program inside the control device 50 can emit light sequentially or randomly. .. As a result, the LEDs 85a, 85b, 85c, and 85d can be made to emit light sequentially or randomly regardless of the rotational operation of the main body 2 of the sprinkler, and light can be emitted in all directions.

【0040】

[Modification 2] In the first embodiment and the first modification, a configuration in which a control device is provided and a rechargeable secondary battery is used as a power storage means has been described. However, it is also possible to have a configuration in which a controller is not provided and a capacitor is used as a power storage means. FIG. 7 is a block diagram of a pest repellent device according to this modified example.

【0041】

The pest repellent device according to this modified example stores and stores the sprinkler 1 for watering, the LED 90 that emits light, the power generation mechanism 91 that generates power based on the kinetic energy of pressure water, and the power generation mechanism 91. It is mainly composed of a capacitor 92 that supplies power to the LED 90, a voltage detector 93 that detects a predetermined voltage, and an LED driver 94 that controls the light emission of the LED 90 based on the detection signal from the voltage detector 93. ing. The LED 90, power generation mechanism 91, capacitor 92, voltage detector 93, and LED driver 94 are arranged on the main body 2 of the sprinkler (see Fig. 1), and rotate integrally with the main body 2 of the sprinkler. ing.

【0042】

In this pest repellent device, the electric power generated by the power generation mechanism 91 is stored in the capacitor 92. Then, the voltage detector 93 detects whether or not the electric power stored in the capacitor 92 has reached a predetermined voltage required for causing the LED 90 to emit light. When a predetermined voltage is reached, the voltage detector 93 sends a detection signal to the LED driver 94 to drive the LED driver 94. By driving the LED driver 94, the electric power stored in the capacitor 92 causes the LED 90 to emit light. When the LED 90 is made to emit light, the electric power of the capacitor 92 is discharged, so the power generation mechanism 91 charges the capacitor 92 again. After that, by repeating this operation, the LED 90 is made to emit light periodically. Since the LED 90 is fixed to the main body 2 of the sprinkler as described above, it can rotate integrally with the main body 2 of the sprinkler and emit light in all directions.

【0043】

As described above, the pest repellent device according to the present modification does not have a control device and uses a capacitor as a power storage means, so that the device configuration is simple and inexpensive.

【0044】
