Abstract

This invention discloses a method for determining the minimum lead weight of a float needed to tighten a fishing line during fishing. The method involves the fishing line and float tip acting as a spring with varying elasticity, and the fishing line and float tip connected in series acting as a spring connected in series between the fishing line and the float tip. Tightening the fishing line requires matching different line sizes with float tips of different diameters. The minimum lead weight determined by tightening the fishing line is related to the line size, float tip diameter, and line length. A preliminary minimum lead weight Q2 is obtained through experiments simulating the tightening of different line sizes in air. Since water is denser than air, the simulated minimum lead weight value in air is relatively small. A revised preliminary minimum lead weight Q1 is obtained through experiments simulating the weightlessness of different line sizes in water, thus determining the final minimum lead weight Q = Q1 + Q2. This invention solves the problem of how much lead weight is needed to tighten a fishing line of varying thickness and length at different fishing depths, providing a basis for selecting the lead weight of the float to ensure timely and effective transmission of both dynamic and static sensitivity of the fishing rig to the float tip.

Description

Technical Field

[0001] This invention relates to the field of fishing technology, and in particular to a method for determining the minimum amount of lead required for a float to taut the fishing line during fishing. Background Technology

[0002] For fishing rig sensitivity, the float's lead capacity is a very important parameter, and it's also a key consideration for anglers when choosing a float. Anglers focus on the float's lead capacity mainly for two reasons: one is to facilitate casting the float, lead, hook, and bait to the fishing spot, which is necessary when the fishing rod is long and the fishing spot is far away; the other is to ensure the line is taut.

[0003] In practical use, if the hook mark on a float is around two marks, the fishing rig has basic sensitivity. Then, according to the full-mark adjustment formula, the hook and bait should be in a suitable underwater state for the fishing conditions, resulting in a clearer float indication of a fish bite. However, if the float's lead weight is too small, the line will bend and twist, the lead weight won't be taut enough, and the line won't have enough strength. This means too much force is wasted on the line when the fish is sucking the bait, affecting the float's indication of a bite and ultimately impacting the rig's sensitivity. Therefore, using a "larger" lead weight to tug on the line is a prerequisite for ensuring rig sensitivity. However, an "excessive" lead weight will directly affect the rig's speed sensitivity (v). Especially when fishing for fish with light bites, the fish's sucking force is weak, and an excessive lead weight makes it difficult for the rig to "start." Therefore, the minimum lead weight of the float is also a very important factor affecting rig sensitivity. It is essentially the connection and guarantee system between the dynamic and static sensitivities of the rig, and deserves in-depth study.

[0004] The hook depth corresponding to the float tip diameter determines the displacement sensitivity of the fishing rig, while the weight of the float lead and water resistance determine the speed sensitivity. Since speed sensitivity is always less than displacement sensitivity, the hook depth corresponding to the float tip diameter plays a crucial role in the rig's sensitivity. Under the premise of an appropriate hook depth, increasing the lead weight within a certain range, while intuitively reducing the rig's movement speed, ensures the line is "taut," guaranteeing that the force of the fish sucking the bait is directly transmitted to the float tip, thus simultaneously increasing both displacement and speed sensitivity. Therefore, appropriately increasing the lead weight generally increases the overall sensitivity of the rig. It's clear that ensuring the lead weight keeps the line taut (or rather, "taut") is paramount. Therefore, it's important to understand that even when fishing for lightly biting fish, appropriately increasing the float's lead weight to "tighten" the line and ensure rig sensitivity is more effective than using a float with "as little" lead weight as possible to reduce rig weight and make it "easier to start." Simply put, more lead is fine; a "loose" line is fatal.

[0005] Invention Patent Content

[0006] The purpose of this invention patent is to provide a method for determining the minimum amount of lead required for a float to maintain a taut fishing line. The technical solution adopted to achieve the above objective is as follows:

[0007] A method for determining the minimum weight of a float needed to keep the fishing line taut during fishing includes the following steps:

[0008] a1. Analyze the movement of the fishing rig in the water. The fishing line and the float are equivalent to a spring with a variable elastic coefficient. The fishing line and the float in series are equivalent to the fishing line spring and the float spring in series. When the fishing line is taut, different line sizes are needed to match different float tip diameters. In fishing, the minimum lead load of the float required to tame the fishing line is related to the line size, float tip diameter, and line length. The initial minimum lead load Q2 is obtained by simulating the tautness of different line sizes in the air. Since the density of water is greater than that of air, the value of the minimum lead load simulated in the air will be smaller. The initial minimum lead load Q1 is corrected by simulating the weightlessness of different line sizes in water. The final minimum lead load Q = Q1 + Q2 is determined.

[0009] b2. In step a1, simulate waterline tension experiments with different line sizes in the air. By designing waterlines of different line sizes and matching them with corresponding float diameters, and increasing the lead weight, obtain preliminary minimum lead load data for different line sizes. Through regression analysis equations, obtain the relationship between waterline length, line size, and preliminary minimum lead load, and determine the preliminary minimum lead load Q2 = 0.30HS, where Q2 is the preliminary minimum lead load, H is the line size, and S is the waterline length.

[0010] c3. In step a1, a weightlessness experiment was conducted on water lines of different sizes in water. By analyzing the weight loss of water lines of different sizes in 1 meter of water, and matching different line sizes with corresponding float diameters, the relationship between the initial minimum elastic lead load correction value and the line size and water line length was obtained using a regression analysis equation. The initial minimum elastic lead load correction value is Q1 = 0.02HS, where Q1 is the lead load correction value, H is the line size, and S is the water line length.

[0011] d4. Based on the preliminary minimum lead content Q2 obtained in step b2 and the preliminary minimum lead content correction value Q1 obtained in step c3, determine the final minimum lead content Q = Q1 + Q2 = 0.32HS, where Q1 is the lead content correction value, Q2 is the preliminary minimum lead content, H is the line number, and S is the waterline length.

[0012] e5. In steps a1, b2, and c3, when conducting experiments simulating the tension of water lines of different sizes in air and the weightlessness of water lines of different sizes in water, the water lines and floats need to work together in series. A proper match between the water line size and the float's tail diameter is required. By designing different water line sizes corresponding to different float tail diameters, a univariate regression analysis equation is used to obtain the relationship between the water line size and the float's tail diameter: H = (1.9~2.4)D. 2 Where H is the line number and D is the drift diameter.

[0013] Preferably, in step e5, five sets of line numbers—0.6, 1, 2, 3, and 5—are used respectively. Based on fishing practice, different float diameter parameters are matched to these line numbers. A univariate regression analysis equation is used to obtain the relationship between line number and float diameter: H = (1.9~2.4)D. 2 Where H is the line number and D is the drift diameter.

[0014] Preferably, in step b2, different 1-meter length lines (line number 1, line number 2, line number 3, and line number 5) are designed. Based on fishing practice, the lead weight is increased by 0.3g, 0.5g, 0.8g, and 1.5g respectively. Then, the lead weight is increased by 0.1g for each of the five line numbers. This makes the elasticity coefficient of the waterline spring 20 to 50 times that of the float spring of the float tail diameter matched with the waterline number. At this point, the waterline is taut. By achieving the taut waterline, the minimum lead weight of the initial elasticity is obtained for different line numbers. By analogy to the case of waterline length S, the relationship between waterline length, line number, and minimum lead weight of the initial elasticity is obtained through regression analysis equation. The minimum lead weight of the initial elasticity is determined to be Q2 = 0.30HS, where Q2 is the minimum lead weight of the initial elasticity, H is the line number, and S is the waterline length.

[0015] Preferably, in step c3, five different sets of line numbers (line 1, line 1.2, line 2, line 3, and line 5) are used to measure the weight loss in 1 meter of water. By analogy with the case of waterline length S, the preliminary minimum elastic lead load correction value Q1 = 0.02HS is obtained through regression analysis equations, where Q1 is the lead load correction value, H is the line number, and S is the waterline length.

[0016] The beneficial effects of this invention patent are as follows:

[0017] This invention relates to a method for determining the minimum lead load of a float required to taut the fishing line during fishing. It analyzes the movement of the fishing rig in the water, and based on the principle that the line and float connected in series are equivalent to a spring connected in series between the line and float, a preliminary minimum lead load Q2 is obtained through simulated line tautness experiments with different line sizes in the air. A revised preliminary minimum lead load Q1 is obtained through simulated weightlessness experiments with different line sizes in water, ultimately determining the final minimum lead load Q = Q1 + Q2. Furthermore, it rationally combines line size and float tip diameter, designing different line sizes corresponding to different float tip diameters, and using a univariate regression analysis equation to obtain the relationship between line size and float tip diameter H = (1.9~2.4)D. 2 The formula of this invention solves the problem of how much lead is needed to ensure the line is taut and "takes force" when fishing at what depth and what thickness of water line. It provides a scientific basis for accurately selecting the lead weight of the float to ensure the timely and effective transmission of both dynamic and static sensitivity of the fishing rig to the float tip, and provides guidance for actual fishing, including selecting the minimum lead weight for fishing rig setup.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The formula derived in this patent is only intended to solve the problem of how much lead is needed to ensure the line is taut and "takes force" when fishing at what depth and with what thickness of water line. It is also an important and practical technology to ensure that the sensitivity of the fishing rig, whether in motion or stillness, can be effectively and promptly transmitted to the float tip to produce a clear fish bite signal. However, it does not take into account the issue of convenient casting.

[0025] like Figure 4 As shown, Figure 4 (a) shows the state of the water line (main line) in the air when it is unwound from the take-up reel. Figure 4(b) represents the experiment in air where the spring constant of the waterline spring is much greater than the spring constant of the matching tail diameter float spring, so that the initial elasticity of the float required to "tighten" the waterline spring in air is minimized by the amount of lead, i.e., Q2. Figure 4 (c) represents the state where the water slightly coils and bends due to weightlessness, and its elasticity coefficient does not reach the level required to be "taut". Figure 4 (d) represents the amount of lead added to the water to compensate for the weight loss of the fishing line, so that the tension of the fishing line meets the sensitivity requirements of the fishing rig. The amount of lead added is the lead correction value Q1.

[0026] Since the fishing line and float are equivalent to a spring with a variable elasticity, connecting them in series is equivalent to connecting the fishing line spring and the float spring in series. When the fishing rig moves in the water, the fishing line spring and the float spring are connected in series, jointly bearing the weight of the float lead, the force of the suspended part of the hook and bait, and the force of the fish sucking in the bait. As the length of the fishing line increases, it is equivalent to connecting another fishing line spring of the same elasticity in series for a certain length. If you want the total length of the fishing line spring to be "taut" as before, you only need to increase the amount of lead weight proportionally to the length. Therefore, the amount of lead weight is directly proportional to the length of the fishing line.

[0027] A method for determining the minimum weight of a float needed to keep the fishing line taut during fishing includes the following steps:

[0028] a1. Analyze the movement of the fishing rig in the water. The fishing line and the float are equivalent to a spring with a variable elastic coefficient. The fishing line and the float connected in series are equivalent to the fishing line spring and the float spring connected in series. When the fishing line is taut, different line sizes are needed to match different float tip diameters. In fishing, the minimum lead weight of the float required to tame the fishing line is related to the line size, float tip diameter, and line length. By simulating the tautness of different line sizes in the air, the initial minimum lead weight Q2 is obtained. Since the density of water is greater than that of air, the value of the minimum lead weight simulated in the air will be smaller. By simulating the weightlessness of different line sizes in water, the initial minimum lead weight Q1 is corrected. The final minimum lead weight Q = Q1 + Q2 is determined.

[0029] b2. In step a1, a waterline tensioning experiment with different line sizes was simulated in the air. By designing 1-meter-long waterlines with different line sizes and matching the corresponding float diameters, the lead weight was increased to obtain the initial minimum lead load data for different line sizes. The relationship between waterline length, line size and initial minimum lead load was obtained through regression analysis equations. The initial minimum lead load was determined to be Q2=0.30HS, where Q2 is the initial minimum lead load, H is the line size, and S is the waterline length.

[0030] c3. In step a1, a weightlessness experiment was simulated on water lines of different sizes. By analyzing the weight loss of water lines of different sizes in 1 meter deep water, the corresponding float diameter was matched with different line sizes. By analogy to the case of water line length S, a regression analysis equation was used to obtain the relationship between the preliminary minimum elastic lead load correction value and the line size and water line length. The preliminary minimum elastic lead load correction value Q1 = 0.02HS, where Q1 is the lead load correction value, H is the line size, and S is the water line length.

[0031] d4. Based on the preliminary minimum lead content Q2 obtained in step b2 and the preliminary minimum lead content correction value Q1 obtained in step c3, determine the final minimum lead content Q = Q1 + Q2 = 0.32HS, where Q1 is the lead content correction value, Q2 is the preliminary minimum lead content, H is the line number, and S is the waterline length.

[0032] e5. In steps a1, b2, and c3, when conducting experiments simulating the tension of water lines of different sizes in air and the weightlessness of water lines of different sizes in water, the water lines and floats need to work together in series. A proper match between the water line size and the float's tail diameter is required. By designing different water line sizes corresponding to different float tail diameters, a univariate regression analysis equation is used to obtain the relationship between the water line size and the float's tail diameter: H = (1.9~2.4)D. 2 Where H is the line number and D is the drift diameter.

[0033] This patent researches the optimal lead weight to "tighten" the waterline spring, ensuring its elasticity is significantly greater than that of the float spring. This reduces the force exerted by the fish sucking the bait on the waterline spring's extension, allowing more of the force to be used on the float's descent, thus guaranteeing sufficient sensitivity even with slight line bending. Therefore, the proper matching of line size and float diameter is paramount.

[0034] Since the unit of float tip diameter is millimeters, and the line number is a quantity related to the cross-sectional area of ​​the waterline, its unit is the square of millimeters. Therefore, the line number is a quantity related to the square of the float tip diameter. Assuming they are positively correlated, we have: H = KD 2 Five line sizes—0.6, 1, 2, 3, and 5—were used, and float tip diameters were matched to these line sizes based on fishing experience. Figure 1 This is a table showing typical line group combinations for line number and drift diameter. Using univariate regression analysis, the equation obtained from the data outside the parentheses is: H = 2.4D. 2 Where H is the line number and D is the drift diameter. The data in parentheses yields the equation: H = 1.9D 2 Where H is the line number and D is the float tip diameter. The final relationship between the line number and float tip diameter is H = (1.9~2.4)D 2 Where H is the line number and D is the drift diameter.

[0035] Use a smaller coefficient for thinner lines and a larger coefficient for thicker lines. Since the minimum lead capacity of the float is primarily to ensure a taut line when fishing for lightly biting fish, and since the floats, hooks, and lines used for this purpose are generally smaller, it's reasonable to set the coefficient k to 2. That is, the line number is approximately equal to the square of twice the float tip diameter. Because the leader line is slightly thinner than the main line and closely related, this matching of the main line and float tip diameter also prevents situations where a thick leader line with a large hook is paired with a small, thin float, or a thin leader line with a small hook is paired with a large, thick float, resulting in the hook depth failing to meet the basic sensitivity requirements of the fishing rig.

[0036] In this patent, the minimum lead weight required to taut the line is determined by matching the float tip diameter to meet the hook mark requirements. The degree of "tautness" depends on the elasticity of the line spring at this lead weight being 20 to 50 times greater than that of the matching float spring. This means the force of the fish sucking the bait will primarily affect the descent of the float spring. In other words, while the line may be slightly curved and coiled, its elongation when connected in series with the float spring is significantly smaller compared to the float spring, thus having a negligible impact on the float's movement. This minimum lead weight ensures the sensitivity of the fishing rig.

[0037] In fishing, the minimum lead weight required for a float to maintain a taut line is related to the line size, float tip diameter, and line length. To determine this minimum lead weight, this patent uses an air-based simulation experiment to determine the minimum elastic lead weight Q2 for different line sizes. During the experiment, 1-meter sections of commonly used mainline lines were cut, with the upper end fixed and the lower end suspended like a spring. A known weight of lead was then added. When the heavy lead reached a certain weight, a smaller weight of lead, such as 0.1 grams, was added. This resulted in the elasticity of the line spring being 20 to 50 times that of the spring of the float tip diameter matched to the line size. The weight of the lead before adding the 0.1 gram is then the minimum lead weight required for the 1-meter line spring to maintain a taut line relative to its matched float tip spring. As for the line length, due to the properties of series springs, the lead weight is directly proportional to the line length.

[0038] Considering that thicker lines are generally used for fishing for large fish in summer, where the bites are more aggressive, a lower multiplier is sufficient. For example, a No. 5 line with a multiplier greater than 20 is fine. It's acceptable for the thicker line to appear as if it has several coils resembling a coiled spring. Because the properties of a series spring are fixed, if the force of a large fish sucking the bait causes the coiled spring to stretch by 2 millimeters, then the corresponding float spring can drop by as much as 4 centimeters! Thinner lines, on the other hand, are generally used for fishing for lightly biting fish in winter and spring. Not only do they require a higher multiplier, but the line also needs to be relatively "straightened" to eliminate water resistance from the spring's surface area. In practice, a multiplier of 50 to 60 is ideal.

[0039] In step b2 of this patent, different 1-meter length lines (line number 1, line number 2, line number 3, and line number 5) are designed. Based on fishing practice, the lead weight is increased by 0.3g, 0.5g, 0.8g, and 1.5g respectively. Then, for each of the five different line numbers, the lead weight is increased by 0.1g. This makes the elasticity coefficient of the line spring 20 to 50 times that of the float spring with the matching float tip diameter, thus tautening the line. This tautness allows for the determination of the minimum lead load for different line numbers. Figure 3 As shown, by analogy to the case of waterline length S, the relationship between waterline length, line number and minimum lead content of the initial elasticity is obtained by fitting the regression analysis equation, and the minimum lead content of the initial elasticity is determined to be Q2=0.30HS, where Q2 is the minimum lead content of the initial elasticity, H is the line number and S is the waterline length.

[0040] Because water is denser than air, the simulated minimum lead load in air will be lower. In air, the coiled lead will naturally sag a significant length due to its own weight. In water, however, the buoyancy of the water causes the lead to lose a substantial amount of weight. This means the coiled lead in water sags less due to its own weight, so the minimum lead load value obtained from the air experiment needs a correction. Regarding the weight loss of lead in water, since lead is much denser than water (13 times greater), the weight loss is less than one-tenth, so the lead weight is ignored in the calculation.

[0041] In step c3 of this patent, five different sets of line numbers (line 1, line 1.2, line 2, line 3, and line 5) are used to measure the weight loss in water at a depth of 1 meter. Figure 2 As shown, when a No. 1 mainline is lowered from the mainline reel into the water to become a waterline, it loses 0.0212 grams of weight, which can be simplified to 0.02 grams. The ratio of line sizes is equal to the ratio of their cross-sectional areas, so the volume ratio of mainlines of the same length but different line sizes is equal to the line size ratio. By analogy to the case of the waterline length S, the preliminary minimum elastic lead load correction value Q1 = 0.02HS is obtained through regression analysis equations, where Q1 is the lead load correction value, H is the line size, and S is the waterline length.

[0042] If you're fishing for small crucian carp with a 0.8 line at a depth of 1 meter, the additional lead weight needed on top of the experimentally determined lead weight is 0.02 * 0.8 * 1 = 0.016 grams. This lead weight adjustment is small, but this extra lead weight can cause a float with a 0.5 mm tip diameter to drop 8.4 cm, or more than 8 marks. Even with a thicker float with a 1.5 mm tip diameter, this amount of lead can cause the float tip to drop nearly 1 mark. If you're fishing for large fish with a 5 line at a depth of 6 meters, the additional lead weight needed on top of the experimentally determined lead weight is 0.02 * 5 * 6 = 0.6 grams. This lead weight adjustment is considerable, so it's necessary.

[0043] Based on the preliminary minimum lead content Q2 obtained in step b2 and the preliminary minimum lead content correction value Q1 obtained in step c3, the final minimum lead content Q is determined as Q = Q1 + Q2 = 0.32HS, where Q1 is the lead content correction value, Q2 is the preliminary minimum lead content, H is the line number, and S is the waterline length.

[0044] The method for calculating the waterline length S. For example... Figure 5 As shown, in ordinary platform fishing, the float depth is generally two or three segments, about 2 to 4 centimeters, while the fishing depth ranges from about 1.5 meters in fishponds to three to five meters in wild fishing. This means that the length of the float segment and tip above the water is extremely small relative to the fishing depth, and its impact on the line length factor in calculating the amount of lead needed to tame the line is negligible. Therefore, the length of the float segment and tip above the water can be ignored. Similarly, the typical 2 to 3 centimeters of lead length can also be ignored. On the other hand, platform fishing requires the hook and bait to be both suspended and submerged, meaning the shorter leader is under vertical force, while the longer leader is bent and not under force. Therefore, the line length S can be obtained by subtracting the float length and then the leader length from the fishing depth. Thus, the extra subtraction of the float segment and tip length above the water is partially offset by the insufficient subtraction of the lead length, resulting in a very small error. That is: S = L - P - Z. Where S is the length of the fishing line, L is the fishing depth, P is the length of the float, Z is the length of the leader line, K is the length of the sinker, and M is the length of the float above the water surface.
