The fin with the pressure regulating valve or the bionic tail fin with the pressure regulating valve has a rigidity regulating function, and the pressure of liquid, gas, lubricating grease, non-Newtonian fluid or DEFLEXION damping material filled in the liquid storage cavity or the gas storage cavity can be regulated by rotating the force regulating screw, so that the longitudinal bending rigidity of the fin with the pressure regulating valve or the bionic tail fin is regulated, and the propelling power of the fin with the pressure regulating valve or the bionic tail fin is regulated.
The deeper the force adjusting screw is screwed in, the larger the force adjusting elastic element in the energy storage cavity and the compression force of the gas in the direction along the longitudinal axis of the energy storage cavity are, the energy storage in the energy storage cavity is increased, the pressure in the liquid storage cavity and the pressure in the air storage cavity are correspondingly increased, the larger the initial longitudinal bending rigidity of the fin with the pressure adjusting valve or the bionic tail fin with the pressure adjusting valve is, when a swimmer swings the fin with the pressure adjusting valve or the bionic tail fin with the pressure adjusting valve, the pressure adjusting valve enables the fin plate, the fin plate or the longitudinal keel to have stronger capability of resisting up-down bending deformation, so that the swimming speed is improved, and the higher propulsion efficiency is still maintained at a high swimming speed; conversely, the smaller the initial longitudinal bending stiffness of the fin with a pressure regulating valve or the bionic tail fin with a pressure regulating valve, when a swimmer swings the fin with a pressure regulating valve or the bionic tail fin with a pressure regulating valve, the pressure regulating valve weakens the ability of the fin plate, the fin plate or the longitudinal keel to resist up-and-down bending deformation, thereby reducing the swimming speed and still maintaining higher propulsion efficiency at low swimming speeds. In short, the pushing power of the fin with the pressure regulating valve or the bionic tail fin with the pressure regulating valve can be regulated by regulating the screwing depth of the force regulating screw, namely, the manual speed change function is realized. The initial longitudinal bending stiffness is a preset longitudinal bending stiffness.
And removing the plunger cylinder in the pressure regulating valve and the force regulating elastic element in the energy storage assembly, namely, only reserving an energy storage cavity and a force regulating screw in the energy storage assembly by the pressure regulating valve, wherein the energy storage cavity replaces the original cylinder barrel to be immersed into a butt joint interface of the fin or the bionic tail fin, so that the energy storage cavity and the fin or the bionic tail fin are butted into a whole along the longitudinal axes of each other.
The connection mode of the energy storage cavity and the butt joint interface comprises, but is not limited to, threaded connection, bonding, threaded connection and bonding, and is usually threaded connection; after the plunger cylinder and the force-adjusting elastic element are removed, the structure of the pressure regulating valve is simplified, and the force-adjusting screw can still be rotated to adjust the pressure of liquid, gas, lubricating grease, non-Newtonian fluid or a DEFLEXION damping material filled in the liquid storage cavity or the gas storage cavity, so that the longitudinal bending rigidity of the fin or the bionic tail fin with the simplified pressure regulating valve is adjusted, and the propelling power of the fin or the bionic tail fin is further adjusted.
The plunger cylinder and the energy storage component of the pressure regulating valve are integrally replaced by an energy accumulator commonly used in hydraulic pressure, namely, the energy accumulator commonly used in hydraulic pressure flushing is miniaturized and then is in butt joint with a liquid storage cavity or a gas storage cavity arranged on the fin or the bionic tail fin along the longitudinal axes of the fin or the bionic tail fin through a butt joint interface. The accumulator is typically a balloon accumulator, the balloon being filled with a gas, typically nitrogen.
In the previous paragraph, the swimmer swings the flipper or the bionic flipper, and accordingly liquid in the liquid storage cavity or gas in the gas storage cavity is compressed, so that the air bag of the energy accumulator is extruded; the initial energy storage size of the energy accumulator can be adjusted by controlling the air quantity charged into the air bag of the energy accumulator or adjusting the adjusting screw at the tail part of the energy accumulator, so that the initial longitudinal bending rigidity of the fin with the energy accumulator or the bionic tail fin with the energy accumulator is adjusted, and the propulsion power of the bionic tail fin with the energy accumulator is further adjusted, namely, the manual speed change function is realized. The initial longitudinal bending stiffness is a preset longitudinal bending stiffness.
The hydraulic pressure energy accumulator is characterized in that a hydraulic pressure check valve is added between the miniaturized hydraulic pressure energy accumulator and the butt joint interface, namely the hydraulic pressure energy accumulator is replaced by the check valve to be in butt joint with the butt joint interface, so that the energy accumulator, the check valve, one of the liquid storage cavity and the air storage cavity are connected in series together along the same longitudinal axis, the check valve can only be opened in the direction of releasing pressure to the energy accumulator, and a throttling hole which longitudinally penetrates through at least one valve core, namely a damping hole, is formed in the sealing surface or the longitudinal axis of the valve core of the check valve.
In the last paragraph, as the flow speed of liquid or gas flowing through the throttle hole on the valve core is higher, the damping effect is more obvious, the pressure difference between the inner side and the outer side of the valve core of the one-way valve is increased, the pressure in the liquid storage cavity or the air storage cavity on the outer side of the valve core is higher than the pressure in the energy accumulator, and after the energy accumulator and the one-way valve are increased, the original liquid storage cavity or the air storage cavity has the characteristic of automatically changing rigidity along with the speed.
The air quantity charged into the air bag of the energy accumulator is increased or the adjusting screw at the tail part of the energy accumulator is screwed in deeper, the energy storage in the air bag of the energy accumulator is increased, the pressure in the liquid storage cavity and the air storage cavity is correspondingly increased, the initial longitudinal bending rigidity of the fin or the bionic tail fin is larger, otherwise, the initial longitudinal bending rigidity of the fin or the bionic tail fin is smaller, and the initial longitudinal bending rigidity is the preset longitudinal bending rigidity.
In the previous paragraph, when the swimmer swings the fin or the bionic tail fin, the fin plate or the longitudinal keel changes in shape in the process of bending up and down, the volume of the liquid storage cavity or the air storage cavity correspondingly changes, and the pressure rises; in the middle of the primary leg swinging action of a swimmer, liquid in a liquid storage cavity or gas in a gas storage cavity is forced to flow through an orifice of a valve core of a one-way valve under the action of pressure, when the secondary leg swinging action is finished and the reverse leg swinging is started, the pressure of the liquid in the liquid storage cavity or the gas in the gas storage cavity is reduced to the lowest value, the valve core of the one-way valve is opened due to the forward back pressure provided by an energy accumulator, redundant liquid or gas in the energy accumulator and outside an air bag is instantaneously extruded into the liquid storage cavity or the gas storage cavity, the pressure of the inner side and the outer side of the valve core is balanced, and the valve core is reset and closed under the action of the elasticity of a reset elastic element carried by the one-way valve; as the frequency or rate of swing of a swimmer's leg is higher, the higher the flow rate of liquid or gas flowing through the orifice on the spool is, the more obvious the damping effect is, the higher the pressure difference between the inside and outside of the spool is, the stronger the ability of the fin plate, fin plate or longitudinal keel to resist bending deformation up and down is, the greater the longitudinal bending stiffness of the fin plate or bionic tail fin is, thereby improving the speed of swimming and still maintaining higher propulsion efficiency at high speed of swimming; conversely, as the swimmer's leg swing frequency or rate is lower, the fin, fin or longitudinal keel is weaker against bending deformation up and down, the longitudinal bending stiffness of the fin or bionic tail fin is smaller, thereby reducing the speed of swimming and still maintaining higher propulsive efficiency at low speed of swimming; in short, as the frequency or rate of the swimmer's swing leg is higher, the characteristic of automatic stiffness variation with speed of the flipper or the bionic tail fin is more remarkable, and the propulsive power of the flipper or the bionic tail fin is greater, i.e., the flipper or the bionic tail fin has a speed change function.
The liquid storage cavity or the air storage cavity in the hollow taper pipe of the fin plate, the fin plate or the longitudinal keel is filled with non-Newtonian fluid or a DEFLEXION damping material; inside the fin plate, the liquid storage cavity or the gas storage cavity in the fin plate or inside the cone pipe, a diaphragm is arranged, a non-Newtonian fluid or a DEFLEXION damping material is arranged inside the diaphragm, conventional liquid, conventional gas or lubricating grease is filled outside the diaphragm, and the diaphragm is communicated with a pressure regulating valve, so that the diaphragm can block the mutual penetration of media at two sides of the diaphragm and can transmit pressure from one side to the other side of the diaphragm.
The longitudinal axis of the taper pipe is a curve or a straight line, the cross section of the taper pipe inner cavity vertical to the longitudinal axis of the taper pipe is non-circular or circular, and the perimeter of the cross section of the taper pipe inner cavity gradually decreases from the front end of the advancing direction of the swimmer to the rear end of the advancing direction of the swimmer.
The non-Newtonian fluid is a speed sensitive material, and hardens along with the increase of the bending rate of the liquid storage cavity or the gas storage cavity, so that the fin or the bionic tail fin has the characteristic of automatically changing stiffness along with the speed; the DEFLEXION damping material is a pressure sensitive material, and becomes hard along with the rising of the pressure in the liquid storage cavity or the gas storage cavity, so that the fin or the bionic tail fin has the characteristic of automatically changing stiffness along with the speed.
In the previous paragraph, the non-newtonian fluid may be replaced with other speed-sensitive materials, which may also harden with an increase in the bending rate of the liquid storage chamber or the gas storage chamber, and may also make the fin or the bionic tail fin have an automatic stiffness-changing characteristic with speed; the DEFLEXION damping material can be replaced by other pressure sensitive materials, the other pressure sensitive materials can also harden along with the rising of the pressure in the liquid storage cavity or the gas storage cavity, and the fin or the bionic tail fin can also have the characteristic of automatically changing stiffness along with speed.
When a swimmer swings the fin or the bionic tail fin, the liquid storage cavity or the gas storage cavity filled with the non-Newtonian fluid or the DEFLEXION damping material is extruded, bent and sheared in the process of bending up and down, the volume is changed, the non-Newtonian fluid or the DEFLEXION damping material in the liquid storage cavity or the gas storage cavity is extruded, bent and sheared, the higher the frequency or the speed of swinging legs of the swimmer is, the higher the frequency or the speed of the non-Newtonian fluid or the DEFLEXION damping material is extruded, bent and sheared is, the pressure in the liquid storage cavity or the gas storage cavity is correspondingly increased, the greater the longitudinal bending rigidity of the liquid storage cavity or the gas storage cavity is, the rigidity characteristic is obvious along with the speed, and therefore the swimming speed is improved, and the higher propulsion efficiency is still kept at the high swimming speed; conversely, the lower the frequency or rate at which the swimmer swings his legs, the less the longitudinal bending stiffness of the reservoir or reservoir, thereby reducing the speed of travel and still maintaining a higher propulsive efficiency at low speeds of travel.
In the swimming posture state that the swimmer lies on the water, an upper clamping piece and a lower clamping piece which are used for clamping the liquid storage cavity or the gas storage cavity in the middle are respectively arranged at the upper part and the lower part of the fin plate, the fin plate or the longitudinal keel which are parallel to the upper surface and the lower surface of the fin plate and are tangential or parallel to the inner wall of the liquid storage cavity or the gas storage cavity.
The wedge-shaped cavity is added after the upper clamping piece and the lower clamping piece, and the change of the rigidity of the wedge-shaped cavity is more obvious under the upper and lower clamping actions of the upper clamping piece and the lower clamping piece in the process that a swimmer swings the fin or the bionic tail fin, so that the rigidity adjusting function of the fin or the bionic tail fin is more outstanding; the upper and lower clips may also extend to the full area of the fin panel of the fin except for the portion of the wrapping foot, or to the full area of the fin plate of the bionic tail fin except for the portion of the fixing foot, to increase the acting volume of the upper and lower clips, thereby further increasing the intuitiveness of the variation of the wedge-shaped cavity rigidity, and also further enhancing the rigidity adjusting function of the fin or the bionic tail fin.
The upper clamping piece and the lower clamping piece are used for further enhancing the degree of volume change of the liquid storage cavity or the gas storage cavity in the process of bending up and down in the leg swinging process of the swimmer, so that the fin with the pressure regulating valve or the rigidity regulating function with the bionic tail fin is further enlarged.

The force adjustment elastic element 104 is usually a compression spring, and the force adjustment screw 105 is rotated inwards, the force adjustment elastic element 104 is compressed, or the gas in the energy storage cavity 103 is compressed, or both the force adjustment elastic element 104 and the gas in the energy storage cavity 103 are compressed, and the energy storage in the energy storage cavity 103 is increased.
Embodiment two: as shown in fig. 4, the present invention has both the left and right side of the double-foot fin with the pressure regulating valve 1.
The double-foot single-web mainly comprises web panels 201, left and right longitudinal keels 202 and a butt joint interface 203.
In this embodiment, the left and right longitudinal keels 202 are hollow taper pipes, and the large ends of the taper pipes are columnar butt joints 203, and are respectively connected with a pressure regulating valve 1. The fin panel 201 is hollowed out to form a wedge-shaped cavity after the thickness of the wall thickness is reserved on the rest part except the part wrapping the foot, and the wedge-shaped cavity is communicated with the taper pipes in the left longitudinal keel 202 and the right longitudinal keel 202 to jointly form the liquid storage cavity.
The liquid storage cavity and the cylinder barrel 101 of the plunger cylinder are filled with liquid, and the liquid is usually hydraulic oil or brake oil.
The double-foot single web with the pressure regulating valve 1 has a rigidity regulating function, and the pressure of liquid filled in the liquid storage cavity can be regulated by rotating the force regulating screw 105, so that the longitudinal bending rigidity of the foot web 2 with the pressure regulating valve 1 is regulated, and the propelling power of the foot web is regulated.
The deeper the force adjusting screw 105 is screwed in, the greater the force adjusting elastic element 104 in the energy storage cavity 103 and the compression force applied by the gas along the longitudinal axis direction of the energy storage cavity 103 are, the energy storage in the energy storage cavity 103 is increased, the pressure in the liquid storage cavity is correspondingly increased, the greater the initial longitudinal bending rigidity of the fin 2 with the pressure regulating valve 1 is, when the swimmer swings the fin 2 with the pressure regulating valve 1, the pressure regulating valve 1 makes the ability of the fin panel 201 and the longitudinal keel 202 to resist up-and-down bending deformation become stronger, thereby improving the swimming speed and still maintaining higher propulsion efficiency at high swimming speed; conversely, the smaller the initial longitudinal bending stiffness of the fin 2 with the pressure regulating valve 1, the pressure regulating valve 1 weakens the ability of the fin panel 201, the longitudinal runner 202 to resist bending deformation up and down when the swimmer swings the fin 2 with the pressure regulating valve 1, thereby reducing the swimming speed and still maintaining high propulsion efficiency at low swimming speeds.

The initial longitudinal bending stiffness is a preset longitudinal bending stiffness.
The swimmer can raise the longitudinal bending rigidity of the fin 2 before high-frequency water diversion and high-speed quick travel, and can lower the longitudinal bending rigidity of the fin 2 before low-frequency water diversion and low-speed slow travel, so that the propulsion power of the swimmer can be adjusted according to the needs; the specific gravity of useful work can be effectively improved no matter what frequency the swimmer is in, the advancing efficiency and the swimming speed of swimming and diving are improved to the maximum extent, the physical strength is saved, and the advancing potential of the swimmer in the water is fully exerted.

The double foot single web mainly comprises web panels 201, a left longitudinal keel 202 and a right longitudinal keel 202.
In this embodiment, the fin panel 201 is hollowed out to form a wedge-shaped cavity after the thickness of the wall thickness is reserved in the rest part except the part wrapping the foot, and the wedge-shaped cavity is communicated with the taper pipes in the left and right longitudinal keels 202 to jointly form the liquid storage cavity. The liquid storage cavity is filled with non-Newtonian fluid. The big end of the taper pipe is provided with a blocking cover for blocking.
The non-newtonian fluid is a velocity sensitive material that hardens as the rate at which the reservoir is flexed increases, thereby providing the flipper 2 with an automatic stiffness-changing characteristic with speed.
When a swimmer swings the fin 2, the liquid storage cavity filled with the non-Newtonian fluid is extruded, bent and sheared in the process of bending up and down, the volume is changed, the non-Newtonian fluid in the liquid storage cavity is extruded, bent and sheared, the higher the frequency or the speed of swinging legs of the swimmer is, the higher the frequency or the speed of the non-Newtonian fluid is extruded, bent and sheared is, the pressure in the liquid storage cavity is correspondingly increased, the greater the longitudinal bending rigidity of the liquid storage cavity is, the more obvious the rigidity characteristic of automatic change along with speed is, and therefore the swimming speed is improved, and the higher propulsion efficiency is still kept at the high swimming speed; conversely, the lower the frequency or rate at which the swimmer swings his legs, the less the longitudinal bending stiffness of the reservoir, thereby reducing the speed of travel and still maintaining a higher propulsive efficiency at low speeds of travel.
