Description

The utility model relates to the field of sport and recreational fishing, and more specifically to the design of devices designed to indicate bite, for example, when bottom fishing using bottom spinning gear, fishing rods for winter fishing and others.

Today it is difficult to imagine modern fishing without electronic alarms. The signaling device will inform about the bite in a timely manner, even if you do not see the rods, wake up at night, and allow you to immediately respond to the bite.

Basic requirements for electronic signaling devices:

1. Reliability. Indeed, it is often necessary to catch in the rain and in the fog, and sometimes at sub-zero temperatures. The signaling device will be reliably protected from water and moisture if it has a sealed enclosure and an electric circuit board sealed with sealant.

2. Low power consumption. If the device consumes a lot of energy and the batteries have to be changed almost on every fishing trip.

3. Ease of use.

Electronic signaling devices can differ from each other by the presence of various adjustments and additional options.

In the simplest there is only a volume control, which is adjusted depending on the conditions in which you have to catch: day, night, wind, the distance from the fisherman to the gear.

In some devices, in addition to adjusting the volume, there is a tone control knob. You can adjust the tonality in such a way that by ear you recognize which of the gears a bite has occurred.

In more expensive models, the sensitivity adjustment is also added to the two previous ones. The absence of false signals will make the fishing process much more enjoyable.

In some expensive signaling devices, the sensitivity is regulated not only by turning the toggle switch, but also by a special switch (Delkim Txi), having due to this a very large range.

In addition to various adjustments, professional models have a built-in transmitter that transmits a signal when biting to a special pager located at a distance of 200 meters from the rods and having a volume control. Some companies (Delkim, Solar) produce pagers with a vibration device that can report a bite silently.

In addition to the adjustments listed above, additional options may be present in electronic signaling devices:

- night illumination (Delkim, Solar, FOX);

- anti-theft alarm (Delkim);

- intermittent flashing of the bulb when biting towards the shore and a constant glow when pulling from the shore (FOX);

- indication of low battery (FOX, Delkim, Solar);

- energy-saving mode for cases when the pager is not far from the signaling devices (Delkim);

It is necessary to set up electronic ones on every fishing trip, bringing them in line with the conditions in which you have to fish.

Existing bite alarms of world famous manufacturers, such as Kosadaka (Japan), Cottus (China), Ultimate (Holland), Solar (Great Britain) and other companies, are in a static position on the shore in working position and transmit the signal mainly during longitudinal movement of the fishing line when biting fish. For this purpose, the following sensor design options are mainly applied:

1. LED - operation occurs when the luminous flux is blocked due to the curtain connected by linkage mechanisms with fishing line;

2. Reed switches - triggering occurs when a magnet is connected associated with the fishing line along the reed switch;

3. Contact - actuation occurs when the lever connected with the fishing line to the microswitch is pressed.

However, these structures when fishing, for example, with a winter fishing rod from ice or in summer from a boat, are unacceptable, because it is required to draw smooth oscillatory movements with the jigsaw to attract attention. Any simple movement of the fisherman in the boat, as well as the excitement of a pond from the wind or pass it by water transport, will lead to a false alarm of the above existing sensors.

The bite detector (RU 15625 U) is known from the prior art, comprising a housing, a current source, sound and light signals, an attachment pad for breaking contacts of an electric circuit, characterized in that it is provided with a clip-clamp rotating around an axis, and a contact pad is provided with a spring contact with with a timber holder and a stand-contact with a screw for adjusting the stiffness of the pressure contact and a bite sensitivity screw interacting with the spring contact located on it.

A bite detector is also known (RU 2192742), comprising a holder mounted on a fishing rod, provided with a channel with inlet and outlet openings, and an elastic element passed through the channel of the holder with the possibility of movement along the channel, as well as a signal element associated with the elastic element, characterized in that the axis of the inlet and outlet of the channel of the holder are angled to each other, and the position of the axis of the inlet is fixed relative to the axis of the rod.

The closest solutions are signaling devices (DE 3534710, GR 20060100284), which use a magnetically activated reed contact breaker.

Triggering occurs when a magnet is associated with various mechanisms. In particular, in the solution GR 20060100284 it uses a reed switch to trigger the electronic circuit of the bite indicator by means of a lever mechanism (pendulum), one end of which is connected to the fishing line, and the other with a magnet approaches the reed switch when moving the fishing line and closes the circuit with magnetic flux.

Other well-known solutions work in a similar way, where also one end is connected with moving the fishing line, and the other either presses the microswitch or shuts off the light flux of the photodiode with a “shutter”.

All known solutions are generally based on a pull of fishing line during bite.

As a drawback of all these analog designs is their static nature. The bite indicators are stationary in the standby mode and do not allow any movement of gear, which can lead to false positives.

The solution to these shortcomings can be the use of an inertial bite indicator sensor, consisting of a reed switch and a magnet based on the gravity and inertia of the magnet, which is the purpose of the claimed utility model.

The technical result is the ability to mobility gear without false alarms.

This goal and result is achieved due to the fact that the bite detector, containing a current source, an audio and / or light signal, pads for attaching contacts to break an electric circuit, activated by a reed switch system using a magnet, characterized in that the magnet core is placed in a pencil case or rocker and installed perpendicular to the tension of the fishing line along the rod in the nod zone, and the reed system is made with the possibility of closing / opening the contacts of the reed when biting under the action of raising Whether lowering magnet by inertia.

The core of the magnet is placed in a pencil case and is installed in the nodding zone from below.

Another option implies that a rocker with a magnet is installed along the nod from above or from the side, and the length of the fishing line is selected so that in a calm state without bite, the nod bends downward while the weight of the mormyshka (sinker), and the beam with the magnet remains straightened.

A nod is fixed to the reed housing, which is made of elastic spring steel. Two thin flexible stranded wires from the reed switch to the electrical connector are laid and fixed along the nod.

As electric wires, two springs are used that are separate and insulated from each other, simultaneously playing the role of an electric conductor and the functions of a nod.

A gasket can be installed between the magnet and the reed switch, and such a thickness is made that the magnetic flux of the core closes the contacts of the geocon and at the same time the magnetic force at this distance is less than the gravity of the magnet.

A utility model can be implemented as follows. way.

With a smooth swaying of the nod, the core of the magnet located in the pencil case, due to gravity, is in the lower position and the magnetic flux is not enough to close the contact group of the reed switch (see Figure 1.)

The principle of operation of the inertial sensor is based on the following.

When biting, a sharp twitching of the fishing line (10) occurs, while the magnet (8) by inertia is understood (bounces) and closes the contacts of the reed switch (1) with its magnetic flux. Gasket (7) is necessary to prevent the magnet sticking to the reed switch. Reed elements contain metal, so the magnetic force in the upper position may be greater than its gravity. By practical experience, the thickness of the gasket is selected so that the magnetic flux of the core closes the contacts of the reed switch and at the same time the magnetic force at this distance is less than the gravity of the magnet. Therefore, in some cases, a damping pad may not be necessary.

A command is sent to the electronic circuit of the bite signaling device to supply an audio and / or light signal, for example: a buzzer sounds and / or an LED blinks (12). If the electronic circuit is triggered by an open circuit, the pencil case (9) with a magnet (8) is installed on top of the reed switch housing (1) (see Figure 2).

There is a category of lovers of winter fishing for bream from ice on a “standing fishing rod” in pre-lured places. This design also allows for this purpose to use an inertial sensor (17), but with an additional device. A rocker with a magnet (16) is mounted along the nod from above (side). When casting the bait into the hole (18), the mormyshka (20) (sinker) sinks to the bottom, the length of the fishing line (10) is chosen so that the nod (11) bends down under the weight of the mormyska (20) (Georgian) and the beam with a magnet ( 16) remained straightened. When biting, the bream gently lifts the bait from the bottom, the fishing line (10) loosens, the nod straightens and approaches the rocker magnet (16) and closes the reed contacts by magnetic flux - the electronic circuit of the indicator (14) is activated, while the bite indicator can also work from the bottom magnet in a pencil case as with a normal bite with sharp twitches (see Figure 3). Design features of a nod.

The reed switch and magnet are assembled in separate cases, which, after assembly, are interconnected in the area of the reed switch contact group. A nod (11) made of elastic spring steel is attached to the reed housing. Two thin flexible stranded wires from the reed switch to the electrical connector are laid and fixed along the nod.

It is advisable to use as springs two separated by an insulator (22) insulated springs (4), at the same time playing the role of an electrical conductor and the function of a nod (preferably a flat rectangular section). In this case, it is possible to change the length of the nod springs (4) by moving them along the contact group of the electrical connector, selecting in place the elasticity of the nod for the fishing method (see Fig. 4).

The elasticity of the nod, its length is determined depending on the weight of the mormyshka, the characteristic features of the fishing method and the size of the fish (the nod can be either direct with respect to the whip of the fishing rod, or at an angle). In the same way, the mass of the magnet is also selected. Empirically verified the minimum gap at which the contact closes the reed switch. To prevent sticking of the magnet to the reed switch, this gap is filled with elastic material (porous rubber, polystyrene foam, cork, etc.). The height of the pencil case is set depending on the size of the minimum clearance plus the length of the magnet rod and its working stroke. The movement of the magnet in the pencil case should be free, without distortions and jamming. After collecting the magnet case and the reed switch housing, in order to exclude moisture, which can affect the construction, especially in winter, all openings are sealed (silicone sealant, sealing wax, glue). The shape of the pencil case can be any, depending on the shape of the magnet. As, for example, cylindrical, under the cylindrical shape of the magnet rod. The nod tip (11) may have a clamping screw (24) for attaching to the whip of the fishing rod (15) or its tip (23).

A LED (12) is mounted at the tip, the contacts of which for this simplified electronic circuit are connected to a plug connector, to which a reed switch is also connected in parallel through the conductors. For more complex electronic circuits, the LED can be connected with separate wires. LEDs are preferably used with the function of self-blinking during the passage of electric current.

An electronic circuit of the bite sensor (14) is connected to the plug connector through a plug through wires (21) located along the fishing rod’s whip (15). Using plug connectors, it is easy to replace inertial bite sensors with similar ones with other spring parameters.

Depending on the complexity of the electronic circuit, it is possible to use three or four contact sockets when separate wires are supplied to the LED (12) in order to obtain a blinking light signal for a given time interval.

Figure 5 shows the simplest electronic circuit of an inertial bite detector.

In the right sector, the assembly diagram of the inertial sensor is shown, where HL1 is the LED (signal lamp), S is the reed switch normally open, when approaching to which the permanent magnet E is closed by the magnetic flux of the common circuits? bite indicator.

In the left sector is an electronic circuit of the bite signaling device itself.

The assembled circuit together with the batteries can be located either in a separate housing and mounted on a fishing rod, or directly integrated into the handle. For convenience, when fishing and transporting gear, a switch is installed in a convenient place.

In the central sector, the connecting wires of the fishing rod located along the whip are shown, at the ends of which there are plug plugs for connecting the inertial sensor to the electronic bite indicator circuit (Figure 5), where V1 is the MP-26B transistor; V2 - transistor MP-37B; R - resistor 300-680 Ohms; Tlf - telephone capsule TK-67; L - LED HL1. (AL307B); S - reed switch KEM-1; E is a magnet; B - KBS 4.5 V battery; T - toggle switch.

The capsule of the TK-67 headphone can be replaced by DEM-4M, DMSh, DEMSh-2.

Resistance to its direct current should not exceed 250 Ohms. Instead of the reed switch KEM-6, you can use KEM-1.

When fishing for several fishing rods, at night, as well as in bright sunny conditions, when it is difficult to notice the light indication, an audible alarm is given to the foreground. By changing the frequency of the sound signal, you can adjust the indicators so as to determine by the tone on which fishing rod a bite occurred. It is also important to set the duration of the sound signal. If there was a sharp bite with one or two jerks with an interval of one or two seconds, and that in turn also once or twice worked out an audio and light indication, it is difficult to determine which fishing rod it was. Therefore, the electronic circuit, having received even such a signal from an inertial sensor and a signal from an inertial sensor, is obliged to give a sound and light indication of a predetermined duration, preferably a flashing indication for example 5 seconds.

For convenience, it becomes necessary to temporarily disable it, for example, when:

- raising bait or caught fish:

- changing the bait nozzle;

- transportation of gear.

These tasks are satisfied by the already known electronic circuit using microcircuits (see Fig.6).

In the right sector is an electronic circuit of the bite signaling device assembled on the K561LA7 chip.

In the upper left sector, the connecting wires of the fishing rod located along the whip, at the ends of which there are plug connectors, are shown for connecting the inertial sensor to the electronic bite indicator circuit.

In the lower left sector, the assembly diagram of the inertial sensor is shown, where: HL1 is the LED (AL307B), S is the normally open reed switch, and when approaching the permanent magnet E, the general bite indicator circuit is closed by magnetic flux.

The detector is assembled on one chip and functionally consists of two blocks.

On the elements DD1.1 and DD1.2 a standby single vibrator is assembled. The frequency response circuits of the single-shot are capacitor C1. and resistor R2. With the capacitor rating of 0.47 microfarads indicated on the diagram, the duration of the sound and light signal will be 1 second. With an increase in the capacitor rating to 2.2 microfarads, the duration will increase to 5 seconds. You can put different values on the signaling devices and determine by ear which of the gears a bite occurred.

The positive impulse of the standby single vibrator is triggered by the standby multivibrator assembled on the elements DD1.3 and DD1.4. Frequency-setting elements of the multivibrator are the resistor R3 and the piezoelectric element ЗП1. A multivibrator is excited at the natural resonant frequency of the piezo emitter. For a dozen assembled circuits with a piezo emitter ZP1, it was not necessary to select a resistor. If another piezoelectric emitter is used, it may be necessary to select a resistor at maximum volume. The zero potential of the standby single-shot turns on the HL1 LED. You can put any LED, but a LED with a diffusing lens is better.

In standby mode, at the inputs 29, 30 of the element DD1.2 there is a level of logical zero, at the output 28 - the level of a logical unit. HL1 LED is off. At the inputs 25, 26 of the logic element DD1.1 high levels. At pin 27, a logical zero.

The C1 capacitor is discharged and the multivibrator does not work. When biting with a magnetic flux, the reed switch closes and starts the waiting single-vibrator and the waiting multivibrator. The integrator capacitor C1 will begin to recharge to a logical zero level at terminals 29, 30. The capacitor recharge time determines the pulse duration of a single-shot. It means the time of switching on the sound and light signal.

The signaling device is powered by 27-28 elements of type A10-A13. The standby current consumption is negligible (less than 1 microampere), so the power switch can be omitted. The signal circuit board is made of one-side fiberglass. The topology of the board with the location of the elements shown in Fig.7. The dimensions of the board (about 20 × 27.5 mm) allow it to be mounted in the fishing rod handle. From the end of the fishing rod, it is recommended to make a cavity for power sources, which is closed by a lid on a threaded connection with sealing gaskets. Depending on the characteristic features of fishing tackle, the electronic circuit of the bite indicator and power sources can be made in a separate case.
