[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fishing float incorporating a radio wave transmitter.

[0002]

[Prior art]

 In the past, there were fishing floats that were coated with fluorescent paint or added light-emitting elements, etc., but it is difficult to distinguish fishnets and wind waves from a float that is far away. I was worried about the safety of the scaffold, such as keeping an eye on me.

[0003]

[Problems to be solved by the device]

 Except for its drawbacks, this plan will develop a small, inexpensive float with a radio transmitter that makes it easy for fishermen to catch fish even when they are away from the float, and also pays attention to the security of the scaffold. It is what

[0004]

[Means for Solving the Problems]

Now, the solution means will be described with reference to the drawings. (A) A transmitter 2, a power supply 4 for the transmitter, and an antenna 5 are enclosed in a hollow floating container 1 made of plastic or the like. (B) When the float moves in the vibration direction 6, in the vibration detection unit 3, the metal vibrating piece 8 attached to the other end of the elastic body 7 such as a spring whose one end is fixed in the floating container 1 is connected to the adjacent electric The resonance circuit solenoid coil 9 vibrates relatively, and the inductance L of the coil 9 changes. Then, the parallel resonance frequency f = 1 / (2π (LC) ^1/2 ) of the electric resonance circuit of the transmitter 2 formed by the inductance L and the capacitance C is changed, which corresponds to the floating vibration. Frequency-modulated electric vibrations are generated, which are amplified in the transmitter, and then radio waves are radiated from the antenna 5 into the air.

[0005]

Since the present invention has the above-described structure, when it is used, the vibrating piece 8 or the spring 7 feels a periodic signal due to a wave and a pulse-shaped fishnet, and the signal is It is placed on a frequency-modulated radio wave. A fisherman who is far away can distinguish the fish signal from the sound, light, and vibration generated by the radio wave receiver.

[0006]

【Example】

 Note that (1) the vibrating piece 8 may be placed inside the coil 9, and (2) as shown in FIG. 3, the spring 7 is made of a magnetic material having a relative magnetic permeability greater than 1 in addition to steel, and the spring 7 is made of a spring. The magnetic interaction between the coil and the coil may be used, and (3) the same effect can be obtained by changing the winding diameter of the magnetic spring 7 as shown in FIG. The spring 7 is fixed at one end, but both ends may be fixed and the vibrating piece may be attached to a part of the spring. When the electrically insulated vibrating piece 8 or the spring 7 contacts the coil 9 when vibrating, mechanical vibration is positively generated in the coil, and the coil shape changes due to vibration. It is also possible to obtain a frequency-modulated wave that is strong and corresponds to metallic sounds. In this case, the vibration direction of FIGS. 2 to 4 can be changed by 90 ° in the plane of the drawing. Although the vibration sensing by changing the inductance L is used, the change of the capacitance C resistance R may be used, and the modulation method may be any method such as frequency modulation, amplitude modulation and phase modulation. Absent.

[Effect of device]

 Therefore, even if you look away from the float, you can grasp the movement of the float in the distance in detail, and it can be used both day and night, and can also be used for target fish that are blind. The vibration detector is also simple, so it provides an interesting fishing float that is small and inexpensive.
