Description

Design and implementation method for preventing water drop from being blown into wire by wheel

Technical Field

The invention relates to a water drop wheel of a fishing rod and a using method of the water drop wheel, which are used for the application occasions of preventing a line from being broken when the water drop wheel is cast for fishing, and particularly can effectively prevent the line from being broken when the water drop wheel is used for fishing by using a PE line.

Background

Along with the improvement of living standard of people and the diversification of leisure modes, more and more people select the way to fish as the mode of leisure exercise. When fishing, many people select the water-drop wheel with the gun handle rod as a fishing tool; due to the throwing characteristics of the water droplet wheel and the lure, if the braking force is adjusted to be overlarge, the lure is thrown for a short time; if the braking force is too small, the situation of line explosion (the line sub-lines are wound together on the line cup) can occur, if the situation occurs, the throwing distance is influenced slightly, and the line sub-lines are scrapped seriously to influence fishing; therefore, how to adjust the braking force is particularly important.

In the prior art, the water droplet wheel mostly adopts several modes such as magnetic braking, centrifugal braking, electronic braking and the like to adjust the braking force; the magnetic brake, the centrifugal brake and the electronic brake have the advantages and the disadvantages, the braking force can not be dynamically adjusted by the magnetic brake and the centrifugal brake, and the electronic brake has a complex structure, so that the cost is high.

In view of the problems, the invention provides a novel braking force adjusting method aiming at the use scene of the water droplet wheel by combining the design and the professional experience in the related field; according to scene change, under the condition of different line cup rotational speeds, the control system timely adjusts the braking force of the water droplet wheel, and meanwhile, when a PE line is used, if the line explosion trend occurs, the braking force is timely increased, so that the throwing is simpler and more reliable.

Disclosure of Invention

The invention aims to solve the problem that a braking system provides different braking force according to different flight speeds of the lure in the using process of the water droplet wheel; especially in the process of using the PE wire, when the wire explosion trend occurs, the braking force is increased, thereby realizing the purpose of preventing the wire explosion.

In order to achieve the purpose, the following technical scheme is adopted:

a design and implementation method for preventing water drop wheel from wire explosion comprises a wire cup rotating speed detection system, a brake force adjusting system and a PE wire explosion trend detection system, wherein:

the line cup rotating speed detection system comprises a visible light emitting diode, a light receiving triode, a visible light absorption semicircular ring and a light reflection semicircular ring. When visible light irradiates the light absorption semicircular ring, the light receiving triode cannot receive the light reflection signal, the output signal of the receiving circuit is high level, when the visible light irradiates the light reflection semicircular ring, the light receiving triode receives the light reflection signal, and the output signal of the receiving circuit is low level; when the line cup rotates, the signal received by the receiving circuit is a pulse signal with high and low level changes, the period of the pulse signal is calculated, so that the rotating speed of the line cup is detected, and the control system can dynamically adjust the braking force of the braking system according to the difference of the rotating speed.

The braking force adjusting system comprises two main components, namely an electromagnet and a soft magnet on a wire cup; the iron core of the electromagnet can freely move on the framework along the axial direction of the framework. The soft magnet on the wire cup can be arranged on the side wall of the wire cup or the outer wall of the wire cup; when voltage is applied to two ends of the electromagnet coil, the electromagnet generates a magnetic field, and due to the action of magnetic force, the soft magnet on the wire cup and the iron core of the electromagnet interact to generate attraction magnetic force, so that the iron core of the electromagnet moves towards the direction of the soft magnet; when the line cup rotates, the brake function is formed due to the action of magnetic force and friction force. The braking force can be changed by changing the coil current of the electromagnet, so that the rotating speed of the wire cup can be controlled; the larger the current of the electromagnet is, the larger the braking force is, and the smaller the current is, the smaller the braking force is.

And the PE wire explosion trend detection system comprises a level detection circuit and a conductive cross rod. The end B of the conductive cross bar is one end equivalent to a resistor R4, the wire cup and the wire cup shaft are processed into a conductive integrated structure during processing, and the wire cup shaft E is one end equivalent to a resistor R4. The detection principle is as follows: when the outlet speed of the wire cup is consistent with the flying speed of the lure, the PE wire is not contacted with the conductive cross rod, and for the detection circuit shown in the figure 5, the point level of the detection circuit is working voltage (high level); when the outgoing line speed of the line cup is greater than the flight speed of the lure, the PE line is contacted with the conductive cross rod; because the PE line has certain resistance under the wet state after contacting with water, when the PE line contacts with electrically conductive horizontal pole like this, can produce a partial pressure in the circuit of fig. 5, through detecting the size of partial pressure point voltage, can detect whether the PE line appears the fried line trend when throwing, when appearing the fried line trend, increase braking system's brake dynamics, can realize preventing the purpose of fried line.

In summary, due to the adoption of the technical scheme, the invention has the following effects:

1. the simple structural design is adopted to realize comfortable adjustment of the braking force, so that the throwing is simple and reliable;

2. when using PE wire, possible wire explosion tendencies can be detected;

3. through timely brake adjustment and effective line explosion trend detection, the line explosion condition can be prevented, and the water drop wheel throwing is more stable and reliable.

Detailed Description

The following are embodiments of the invention:

firstly, a line cup rotating speed detection system:

in fig. 7, the light emitting diode and the receiving transistor are fixed on the water dropping wheel side cover, the light emitting direction of the light emitting diode and the receiving direction of the receiving transistor are perpendicular to the D, F plane, and D, F is properly spaced from the light emitting diode and the receiving transistor. When the thread cup rotates along the direction shown in the figures 1 and 2, the light-emitting diode emits visible light, and the receiving phototriode receives the visible light; when the visible light irradiates D and reflects back to the receiving phototriode, the receiving circuit outputs a low level, and when the visible light irradiates F and cannot reflect back to the receiving phototriode, the receiving circuit outputs a high level; therefore, the circuit system receives a series of pulse signals, and the circuit system can obtain the rotating speed of the line cup by calculating the period of the pulse signals. The system control circuit outputs different electromagnet driving currents according to different rotating speeds of the wire cup, so that different magnetic field strengths are controlled, and different braking forces are achieved to control the rotating speed of the wire cup.

II, an electromagnet structure:

the electromagnet consists of an iron core, a framework and a conducting wire wound on the framework, and the iron core can move in the framework along the axial direction of the framework during design. For the wire cup structure of fig. 1, the electromagnet is mounted on the water wheel side cover (electromagnet axis is perpendicular to side cover, parallel to wire cup axis); for the wire cup structure of fig. 2, the electromagnet is mounted on the water wheel side cover (the electromagnet axis is perpendicular to the wire cup axis); when current is applied to a coil of the electromagnet, and the L end of the electromagnet is close to the soft magnet, the iron core of the electromagnet moves towards the direction of the soft magnet ring under the action of magnetic force and friction force, and the wire cup can be prevented from moving towards the directions of fig. 1 and fig. 2 under the action of the magnetic force and the friction force, so that the purpose of braking is achieved.

Thirdly, a braking force adjusting system:

the wire cup is mounted on the water dropping wheel, can not move in the axial direction, and can only rotate along the directions of figures 1 and 2. FIG. 1 shows that the soft magnet is fixed on the side wall of the wire cup, and FIG. 2 shows that the soft magnet is fixed on the outer edge of the wire cup; the braking force adjusting system is mainly realized by a soft magnetic ring C in figures 1 and 2 and an electromagnet in figures 3 and 4.

For the soft magnetic ring mounting of fig. 1: the magnet framework base is installed and fixed on the water dripping wheel side cover. FIG. 3 shows the electromagnet L with end near C; when no current is applied to the electromagnet, L and C are not in contact, and when current is applied, L and C can be tightly attached.

For the soft magnet ring installation mode of fig. 2, the end L of the electromagnet L in fig. 4 is close to the outer wall of the soft magnet ring C, and the contact end of the electromagnet L and the soft magnet ring C is designed into an arc shape, so that the radius of the contact surface of the electromagnet L and the soft magnet ring C is consistent; when no current is applied to the electromagnet, the cambered surface of the L and the cambered surface of the C can be tightly attached;

when current is applied to the coil of the electromagnet, the electromagnet generates magnetic force, due to the action of the magnetic force, the electromagnet iron core and the soft magnet C attract each other, the electromagnet iron core moves towards the C, so that the magnetic force is generated between the iron core and the C, when the wire cup rotates along the directions in the figures 1 and 2, the wire cup is prevented from rotating by the magnetic force and the friction force, the current is applied to the two ends of the electromagnet coil differently, the generated magnetic force and the friction force are also different, so that the control circuit system can control the magnitude of the current according to different rotating speeds, and the purpose of controlling the rotating speed of the wire cup is achieved.

Fourthly, the PE line detection system:

when the PE line is used as the line, the PE line absorbs water during fishing, and the PE line has certain resistance after absorbing water and becomes a conductor. Firstly, designing the wire cup and the wire cup shaft as a conductor in metal contact, and winding the PE wire on the wire cup, so that the PE wire after absorbing water and an E end point of the wire cup shaft form a certain resistance; and secondly, a metal conductor cross rod A (a PE wire detection cross rod which is parallel to the axis of the line cup) is arranged at the upper end of the water drop wheel line cup and is as close to the outer edge of the line cup as possible. When the lure is thrown, if the cup line outgoing speed is consistent with the lure flying speed, the PE line does not contact with the metal conductor A, so that the equivalent resistance R4 (shown in figures 5 and 6) of the end B and the end E is infinite; if the line cup line speed is greater than the lure, the PE line contacts the metal conductor A, so that the equivalent resistance R4 (shown in FIGS. 5 and 6) of the terminals B and E is a certain resistance value.

By selecting an appropriate R3, through the voltage divider circuit shown in fig. 5, when the wire cup outgoing speed is greater than the flight speed of the lure, the PE wire burst detection signal of the voltage divider output circuit becomes low, and when the wire cup outgoing speed is greater than the flight speed of the lure, the PE wire burst detection signal of the voltage divider output circuit is a high level signal VCC.

Selecting proper R3, and when the wire cup outgoing speed is higher than the lure flying speed, the PE wire explosion detection signal of the voltage division output circuit becomes high through the voltage division circuit in the figure 6; when the wire cup outgoing speed is larger than the flying speed of the lure, the PE wire explosion detection signal of the voltage division output circuit is a low-level signal GND.

Therefore, the control circuit system can detect whether the wire explosion happens or not through the change of the PE wire explosion detection signal. If the condition of wire explosion occurs, the driving current of the electromagnet is increased, and the electromagnetic force is increased, so that the rotating speed of the wire cup is reduced, and the wire explosion condition is prevented.

The above embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for those skilled in the art, without departing from the technical idea of the present application, several changes and modifications can be made, which are all within the protection scope of the present application.
