Description

[Detailed Description of the Invention] The present invention is a fish detection device that is attached to a fishing rod and amplifies even a small area (hereinafter referred to as a fish detection) to notify an angler.

Traditionally, when fishing with a set rod, the methods of determining the fish's confidence were to watch the tip of the rod and see how it moved, or by attaching a bell to the rod and listening to the sound it made.

However, the method of watching the tip of the rod made it difficult to identify the fish in the dark or when there were many rods.

Also, with the method of attaching the bell, there was a concern that the bell would not ring for small fish.

This invention was devised to eliminate such drawbacks.
A small container 2 made of metal or synthetic resin in the shape of a pot bottom, a partition plate 3 provided inside the container, and a bimorph oscillator 4, an amplifier 9, a transmitter 10, and a battery 11 sealed inside the partition plate 3. , an elastic backing 5 on the outside of the partition plate 3, a contact 6 made of metal or porcelain partially embedded in the center of the backing, and a small hole 7 provided in the partition plate 3 to pass through the bimorph. A connecting spring 8 tightly connected to the vibrator 4 and the contactor 6
This is a fish detection device consisting of a fish detection detector main body 1, and an antenna wire 13 extending outside the fish detection detector main body 1,
If you receive and amplify the radio waves that will be transmitted using a commercially available portable radio or a dedicated receiver, you can use them as a speaker or receiver.
Since it is possible to make a sound, it becomes possible to know the fish signal even in the dark, even if it is small, and the fishing experience increases.

In addition, since you can see the fish signal even if you are far from the rod, you can wait in a good environment and wait for the fish signal, making it possible to have a safe and enjoyable fishing experience.

This will be explained below with reference to the drawings.

FIG. 1 is a schematic diagram of fishing using this device.

I put all the bait into the water, take up the slack in the line, and wait for the fish to respond, but the trick is when the fish pecks at the bait, and the fish responds when the bait is put in its mouth and pulled. travels along the path 13 to the rod 17, and then to the rod 17.
and reaches the fish signal detector main body 1.

The fish signal detector main body 1 converts the vibrations of the fish signal into an electrical signal and transmits it as a radio wave from the antenna wire 13.

The emitted radio waves are caught by a receiving antenna 14, amplified as necessary by a receiver 15, and are used to make a speaker or a receiver vibrate.

FIG. 2 is an explanatory diagram of the main body 1 of the fish detection detector.

The fish signal detector main body 1 is attached to the rod 17 by crimping as shown in the figure, so the fish signal transmitted to the fishing rod will first be transmitted to the contact 6.
and gives vibration to it.

Next, the vibration of the contactor 6 is transmitted to the bimorph vibrator 4 by the connection spring 8, and a voltage is generated.

This voltage is extracted as an electrical signal, amplified by an amplifier 9, and then transmitted by a transmitter 10 as a radio wave from an antenna line 13.

The reason why the small container 2 is shaped like a pot bottom is to eliminate angular parts as much as possible to prevent fishing lines from getting tangled.

The partition plate 3 supports the backing 5 and prevents water from entering the inside of the detector body.

The connection spring 8 transmits the vibration of the contactor 6 to the bimorph vibrator 4, and also serves to protect the bimorph vibrator 4 by absorbing shocks caused when the fish detector main body 1 is attached to the rod.

Since the backing 5 is made of elastic rubber or synthetic resin, it serves to prevent water from entering the detector body and to softly press the contact 6 against the rod.

The contactor 6 is made of hard metal or magnetism that is resistant to rust and transmits vibrations well.

The bimorph oscillator 4 is made of a piezoelectric element such as Rochelle salt or LHlADP, or an electrostatic element such as barium titanate, and both are suitable for fish signal detection because they are small, lightweight, and inexpensive.

Both the amplifier 9 and the oscillator 10 use transistors or integrated circuits.

The holder 16 that presses the fish detector body 1 onto the rod may have a structure that prevents fishing line from getting tangled and makes it easy to attach and detach the fish detector body 1. In this embodiment, the holder 16 holds the fish detector body 1. It uses a method that is inserted under the container.

If you want to view multiple rods at the same time, you can attach a fish detection device to each rod.

As described above, the present invention has a simple structure that detects fish signals and can transmit radio waves by amplifying the signal, so even small fish signals can be easily detected, there are few malfunctions, and the price is relatively low. It can be expected to be enjoyed by many anglers.
