Description

Technical Field

[0001] The invention relates to the technical field of screw torque transmission, in particular to a novel screw axially driven adjustable flexible eddy current torque transmission device. Background Art

[0002] The screw axially driven adjustable flexible eddy current torque transmission device is a complex mechanical transmission system that combines the characteristics of screw drive, axial adjustment and flexible eddy current torque transmission, among which screw axial drive: screw drive usually uses spiral grooves or threads to transmit power or adjust position; axial drive means that power is transmitted along the axial direction of the screw, which usually involves rotation or linear movement of the screw, adjustable: the design of this transmission device allows the user to adjust it as needed; adjustment may involve changing the position, angle or transmission ratio of the screw to optimize performance or adapt to different working conditions, flexible eddy current torque transmission: eddy current torque transmission is a non-contact transmission method that uses the principle of electromagnetic induction to generate eddy currents in conductors to transmit torque.

[0003] For example, Chinese patent CN102061944B discloses a screw expansion power generation device, the power generation device includes a semi-sealed or fully sealed shell, the shell includes an expander chamber and a generator chamber; the expander chamber and the generator chamber are not connected; a screw expander is arranged in the expander chamber, and a generator is arranged in the generator chamber; the rotor of the screw expander is fixedly connected to the generator rotor, and the power generation device drives the generator to generate electricity through the rotation of the screw expander rotor; the generator chamber is provided with a liquid refrigerant injection inlet and a refrigerant outlet; the generator is cooled by evaporation of the liquid refrigerant. The screw expansion power generation device of the present invention is semi-sealed or fully sealed, the screw expander and the generator are arranged in the shell as a whole, the generator can be a synchronous generator or an asynchronous generator; it can avoid the situation where the refrigerant leaks when the screw expansion generator generates electricity.

[0004] For example, Chinese patent CN102758424A underwater, screw drainage rotary hydroelectric power station, the existing hydroelectric power station relies on building dams on rivers to raise the water level. Due to the geographical location and water source problems of rivers and rivers, this limits the construction of such hydroelectric power stations. Another method is to raise the water level by building dams, but this method has limited water level increase, so the construction of such hydroelectric power stations is restricted. The present invention builds a power station on the bottom of the deep sea. The ocean has vast deep water areas, so the height of the water level is not limited, and the number of power stations built is not limited. It can fully meet the needs of humans to build power stations and solve the human demand for electricity. The present invention is energy-saving and environmentally friendly, does not damage the environment, and does not produce any harmful substances.

[0005] However, the existing screw axially driven adjustable flexible eddy current torque transmission devices are mostly used in renewable energy fields such as hydropower generation. This transmission device can be used to adjust and optimize the operating parameters of power generation equipment and improve energy conversion efficiency. However, for example, a screw expansion power generation device in comparative document 1 generates electricity through a screw, and the screw rotation rate cannot be changed according to actual conditions. If the voltage is unstable, the screw expansion power generation device cannot adjust the screw rotation speed to stabilize the voltage. Under water, for the screw drainage rotary hydropower station in comparative document 2, since the screw is underwater, during the rotation of the screw, the screw will be subject to resistance in the water, resulting in the rotation of the screw being affected. Long-term resistance will affect the service life of the screw. Therefore, a new screw axially driven adjustable flexible eddy current torque transmission device is proposed.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-10 A novel screw axially driven adjustable flexible eddy current torque transmission device comprises a shell 1, a feed port 2, a rotating shaft shell 3, a screw 4, an eddy current motor 5, an eddy current magnetic ring 6, a support rod 7 and a rotating seat 8, wherein a feed port 2 is provided at the upper end of the shell 1, and the front end of the shell 1 is fixedly connected to the rotating shaft shell 3, and two screws 4 are arranged inside the shell 1, and the rear end of the shell 1 is fixedly connected to the eddy current motor 5, and an eddy current magnetic ring 6 is arranged inside the shell 1 corresponding to the lower end of the screw 4, and one end of the eddy current magnetic ring 6 passes through the shell 1 and is connected to the output end of the eddy current motor 5, and the bottom end of the shell 1 is fixedly connected to the support rod 7 corresponding to the middle position of the eddy current magnetic ring 6, and the upper end of the support rod 7 is movably connected to the rotating seat 8, characterized in that it also includes;

[0041] A transmission device is arranged inside the housing 1 corresponding to the side end of the screw 4. The transmission device not only controls the screw 4 to drive axially, but also can beat the eddy current onto the screw 4 to reduce the friction force;

[0042] An adjusting device is arranged on the inner side wall of the shell 1 at the port corresponding to the screw 4, and the adjusting device is used to adjust the spacing gap between the two screws 4. When the device is installed underwater, the shell 1 is installed at the edge corner of the water source, and water enters through the feed port 2 to reach the inside of the shell 1, and then is installed on the outer end of the water source through the eddy current motor 5, and the connecting end of the eddy current magnetic ring 6 is penetrated to the outer end of the shell 1 and the outer end of the water source is connected to the eddy current motor 5, so that a magnetic field is generated in the middle of the eddy current magnetic ring 6, so that it generates eddy currents according to the principle of electromagnetic induction, and the power generated by the eddy current is used to drive the screw 4 to rotate by the transmission device, and the water flow inside the shell 1 is vortexed by the eddy current, so that the screw 4 inside the shell 1 is exposed on the vortex, so as to avoid the screw 4 being affected by the water flow when rotating. , and drives one of the screws 4 to move through the adjustment device at the side end, so that it adjusts the spacing between the two screws 4. In the transmission device, the adjustment of the spacing of the screws will affect the rotation speed. Specifically, when the spacing between the two screws changes, the friction and interaction force between them will also change. If the spacing is too small, it may cause the pitch between the two screws to become smaller, resulting in increased friction, which in turn affects the increase in rotation speed; if the spacing is too large, it will cause the pitch between the two screws to become larger, which will only affect the rotation of the other screw to the maximum extent, reduce its friction, and then affect the reduction in rotation speed. Therefore, the rotation speed of the screw 4 can be affected by the adjustment device, thereby rotating the shaft 9 in the shaft housing 3.

[0043] The shaft shell 3 is set in a long cylindrical shape, and a shaft 9 is movably connected to the inner wall of the shaft shell 3, and one end of the shaft 9 extends into the interior of the shell 1, and a gear 10 is fixedly connected to the end of the shaft 9 corresponding to the interior of the shell 1, and a support plate extends from the inner wall of the shell 1 corresponding to the upper end of the shaft 9, and a plurality of small connecting gears are movably connected to the support plate, and the gear 10 is meshed with one end of the connecting gear.

[0044] The two screws 4 are respectively a fixed rotating screw 11 and a movable rotating screw 12, and the fixed rotating screw 11 is movably connected to the inner wall of the housing 1, and the two ends of the movable rotating screw 12 are movably sleeved with moving blocks 13, and moving grooves 14 are opened on the side walls of the two ends of the housing 1, and the two moving blocks 13 are movably connected to the two moving grooves 14, and one end of the movable rotating screw 12 corresponding to the rotating shaft 9 is fixedly connected to a second gear 15, and the second gear 15 and the connecting gear are meshed with each other, and the fixed rotating screw 11 is used as a screw drive Power, and the mobile rotating screw 12 is used as a mobile screw, so that the distance between the mobile rotating screw 12 and the fixed rotating screw 11 is adjusted during the movement, thereby changing the rotational force of the mobile rotating screw 12, and the mobile rotating screw 12 rotates the connecting gear on the housing 1 through the second gear 15 after having the driving force, and rotates after multiple connecting gears are engaged with each other, so that it completes the rotation of the gear 10 on the rotating shaft 9, and the rotation of the gear 10 drives the rotating shaft 9 to rotate, thereby realizing transmission with other objects.

[0045] The transmission device includes a rotating gear 16, a support frame 17, a second rotating shaft 18, a connecting rod 19, a limiting column 20, a linkage rod 21, a linkage plate 22 and a third rotating shaft 23. The upper end of the rotating seat 8 is movably connected with the rotating gear 16, and a pillar is fixedly connected to the side end of the fixed rotating screw 11 on the inner bottom wall of the shell 1, and the upper end of the pillar is fixedly connected to the support frame 17, and the second rotating shaft 18 is movably connected in the support frame 17, and the lower end of the second rotating shaft 18 is located in the support frame 17 and is fixedly connected to the second rotating gear 38, and the second rotating gear 38 is fixedly connected. 8 is movably connected with the rotating gear 16 through a belt, and a linkage plate 22 is provided at the upper end of the second rotating shaft 18, and a connecting rod 19 is fixedly connected to the side end of the support frame 17, and the upper end of the connecting rod 19 is fixedly connected to the limiting column 20, and the limiting column 20 is movably connected with the third rotating shaft 23, and a linkage rod 21 is provided at the upper end of the linkage plate 22, and the outer end of the third rotating shaft 23 is fixedly connected to the fixed rotating screw 11. When the eddy current motor 5 generates a magnetic field in the eddy current magnetic ring 6 through the principle of electromagnetic field, the rotating shaft on the rotating seat 8 in the inner part thereof is rotated. The gear 16 rotates, and the rotation of the rotating gear 16 drives the second rotating gear 38 to rotate through the belt, and the rotation of the second rotating gear 38 causes the second rotating shaft 18 fixed to the support frame 17 on the support rod 7 to rotate, and the rotation of the second rotating shaft 18 causes the linkage plate 22 to rotate, and the three linkage rods 21 on the linkage plate 22 drive the rotation of the second linkage plate 24 during the rotation of the linkage plate 22, and a horizontal linkage plate 22 uses the L-shaped linkage rod 21 when rotating, because the linkage rod 21 is vertical In the horizontal direction, the corresponding movable groove 25 on the horizontal linkage plate 22 will drag the corresponding movable groove 25 of the second linkage plate 22 to rotate to the corresponding position. As a result, during the horizontal rotation of the linkage plate 22, the second linkage plate 22 will be rotated through the linkage rod 21, and the third rotating shaft 23 is connected to the center position of the second linkage plate 22, so that the second linkage plate 22 can rotate the third rotating shaft 23, and one end of the third rotating shaft 23 is connected to the fixed rotating screw 11, so that the third rotating shaft 23 can complete the driving force on the fixed rotating screw 11.

[0046] The connecting rod 19 is arranged in an inclined shape, and a triangle position arrangement is formed between the support frame 17 , the connecting rod 19 and the limiting column 20 .

[0047] The end of the third rotating shaft 23 away from the fixed rotating screw 11 is fixedly connected to the second linkage plate 24, and the linkage plate 22 and the second linkage plate 24 are both arranged in a triangular shape, and movable grooves 25 are opened at the three corners of the linkage plate 22 and the second linkage plate 24, and the linkage plate 22 and the second linkage plate 24 are arranged perpendicular to each other, and the linkage plate 22 and the second linkage plate 24 correspond to three movable grooves 25 respectively, and three linkage rods 21 are movably connected with each other. Since the linkage plate 22 and the second linkage plate 24 are both triangular in shape and perpendicular to each other, when the corresponding movable grooves on the linkage plate 22 and the second linkage plate 24 When the linkage plate 22 and the corresponding movable groove 25 on the second linkage plate 24 are close to each other, the linkage rods 21 will extend a lot to each other, and when the linkage plate 22 and the corresponding movable groove 25 on the second linkage plate 24 are away from each other, the linkage rod 21 will extend inward, thereby realizing the phenomenon of the three linkage rods 21 being pushed outward, and the outer end of the linkage rod 21 is connected with a pushing plate 26, so that when the linkage plate 22 and the corresponding movable groove 25 on the second linkage plate 24 are close to each other, the extended linkage rod 21 will drive the pushing plate 26 to beat the vortex water towards the two screw rods 4 to make the two screw rods 4 in a wet state, thereby helping to reduce friction and further improve transmission efficiency.

[0048] The three linkage rods 21 are arranged in an L shape, and one end of the three linkage rods 21 corresponding to the outside of the second linkage plate 24 is fixedly connected with a pushing plate 26 .

[0049] The adjusting device comprises a fixed block 27, a rotating rod 28, a hand crank 29, a tilting column 30, a piston block 31, a second connecting rod 32, a second piston block 33, a second fixed block 34 and an adjusting rod 35. The fixed block 27 is fixedly connected to the inner wall of the shell 1, and the rotating rod 28 is movably inserted on the fixed block 27, and the rotating rod 28 penetrates the shell 1 and extends to the outer end, and the hand crank 29 is fixedly connected to one end of the rotating rod 28 corresponding to the outer side of the shell 1, and the tilting column 30 is fixedly connected to the other end of the rotating rod 28 corresponding to the fixed block 27, and the piston block 31 is movably sleeved on the tilting column 30, and one end of the piston block 31 is fixedly connected to the second connecting rod 32, and the second piston block 33 is movably sleeved on the second connecting rod 32, and the adjusting rod 35 is arranged on the second piston block 33, and the second fixed block 34 is fixedly connected to the inner wall of the shell 1, and the adjusting rod 35 and the second fixed block 34 are movably inserted together, and the other end of the adjusting rod 35 is movably connected to the moving block 13.

[0050] The tilting column 30 and the rotating rod 28 are set at a slightly inclined angle, and two resisting plates 36 are extended from one end of the second piston block 33, and one end of the adjusting rod 35 is set in a square shape, and the adjusting rod 35 is clamped between the two resisting plates 36, and a connecting shaft 37 is movably connected between the two resisting plates 36, and the connecting shaft 37 penetrates the resisting plates 36 and is movably connected to the adjusting rod 35. When the rotation speed of the rotating shaft 9 needs to be adjusted, the fixed block 27 is installed on the side wall of the shell 1, and the rotating rod 28 penetrates the fixed block 27 as a support and extends out of the water source, so that a hand crank 29 is installed at the outer end, so that the rotating rod 28 is rotated by rotating the hand crank 29 at the outer end, and the rotating rod 28 is located at the tilting column 30 at one end of the shell 1. The tilting column 30 and the rotating rod 28 are rotated because there is a slight angle of inclination between the tilting column 30 and the rotating rod 28 Therefore, the tilting column 30 is rotated by the rotating rod 28 to form a circular trajectory, and a piston block 31 is movable on the tilting column 30. The piston block 31 and the second connecting rod 32 form an L-shaped state, so that the second connecting rod 32 is tilted due to the tilt angle of the tilting column 30, and the second piston block 33 will move on the second connecting rod 32. Therefore, the second connecting rod 32 is tilted at an angle and slightly displaced inwards and outwards. The small displacement generated on the second connecting rod 32 will pull the adjusting rod 35 to move inwards and outwards, thereby realizing the movement of the moving block 13 on the moving groove 14, thereby realizing a small movement of the moving rotating screw 12 through the moving block 13, changing the spacing between the moving rotating screw 12 and the fixed rotating screw 11, changing the pitch, and thus changing the rotation speed of the rotating shaft 9.

[0051] Working principle: When the device is installed underwater, the shell 1 is installed at the edge corner of the water source, and water enters through the feed port 2 to reach the inside of the shell 1, and then is installed at the outer end of the water source through the eddy current motor 5, and the connection end of the eddy current magnetic ring 6 is penetrated to the outer end of the shell 1 and the outer end of the water source to connect to the eddy current motor 5, so that a magnetic field is generated in the middle of the eddy current magnetic ring 6, so that it generates eddy currents using the principle of electromagnetic induction, and the power generated by the eddy current is used to drive the screw 4 to rotate by the transmission device, and the water flow inside the shell 1 is vortexed by the eddy current, so that the screw 4 inside the shell 1 is exposed on the vortex, so as to avoid the screw 4 being affected by the water flow when rotating, and one of the screws is driven by the adjustment device at the side end. The rod 4 is displaced to adjust the spacing between the two screws 4. In the transmission device, the spacing adjustment of the screws will affect the rotation speed. Specifically, when the spacing between the two screws changes, the friction and interaction force between them will also change. If the spacing is too small, the pitch between the two screws may become smaller, resulting in increased friction, which in turn affects the increase in rotation speed; if the spacing is too large, the pitch between the two screws will become larger, which will only affect the rotation of the other screw to the maximum extent, reducing its friction, thereby affecting the reduction in rotation speed. Therefore, the rotation speed of the screw 4 can be affected by the adjusting device, thereby rotating the shaft 9 in the shaft housing 3;

[0052] When the eddy current motor 5 generates a magnetic field in the eddy current magnetic ring 6 through the principle of electromagnetic field, the rotating gear 16 on the rotating seat 8 inside it rotates, and the rotation of the rotating gear 16 causes the second rotating shaft 18 fixed in the support frame 17 on the support rod 7 to rotate, and the rotation of the second rotating shaft 18 causes the linkage plate 22 to rotate, and the three linkage rods 21 on the linkage plate 22 drive the rotation of the second linkage plate 24 during the rotation of the linkage plate 22, and when a horizontal linkage plate 22 rotates using the L-shaped linkage rod 21, since the linkage rod 21 is vertical The corresponding movable groove 25 on the horizontal linkage plate 22 will drag the corresponding movable groove 25 of the second linkage plate 22 to rotate to the corresponding position, thereby, during the horizontal rotation of the linkage plate 22, the second linkage plate 22 will be rotated through the linkage rod 21, and the third rotating shaft 23 is connected to the center position of the second linkage plate 22, so that the second linkage plate 22 can rotate the third rotating shaft 23, and one end of the third rotating shaft 23 is connected to the fixed rotating screw 11, so that the third rotating shaft 23 completes the driving force on the fixed rotating screw 11;

[0053] Since the linkage plate 22 and the second linkage plate 24 are both triangular in shape and perpendicular to each other, when the corresponding movable grooves 25 on the linkage plate 22 and the second linkage plate 24 are close to each other, the linkage rods 21 therein will extend a lot from each other, and when the linkage plate 22 and the corresponding movable grooves 25 on the second linkage plate 24 are away from each other, the linkage rods 21 will extend inward, thereby achieving the phenomenon of the three linkage rods 21 being pushed outward, and the outer ends of the linkage rods 21 are connected to the pushing plates 26, so that when the corresponding movable grooves 25 on the linkage plate 22 and the second linkage plate 24 are close to each other, the extended linkage rods 21 will drive the pushing plates 26 to slap the vortex water toward the two screw rods 4 to make the two screw rods 4 in a wet state, thereby helping to reduce friction and further improve transmission efficiency;

[0054] When the rotation speed of the rotating shaft 9 needs to be adjusted, the fixed block 27 is installed on the side wall of the shell 1, and the rotating rod 28 passes through the fixed block 27 as a support and extends out of the water source, so that a hand crank 29 is installed on the outer end, so that the rotating rod 28 is rotated by rotating the hand crank 29 at the outer end, and the rotating rod 28 is located at the inclined column 30 at one end of the shell 1. Since there is a slight angle of inclination between the inclined column 30 and the rotating rod 28, the inclined column 30 is rotated by the rotation of the rotating rod 28 to form a circular trajectory, and the active part on the inclined column 30 The piston block 31 is movable, and the piston block 31 and the second connecting rod 32 form an L-shaped state, so that the second connecting rod 32 is inclined due to the inclination angle of the inclined column 30, and the second piston block 33 moves on the second connecting rod 32. Therefore, the second connecting rod 32 is tilted at an angle and slightly displaced inwards and outwards. The small displacement generated on the second connecting rod 32 will pull the adjusting rod 35 to move inwards and outwards, thereby realizing the movement of the moving block 13 on the moving groove 14, and thus realizing the small movement of the moving rotating screw 12 through the moving block 13;

[0055] By using a fixed rotating screw 11 as the driving force of the screw, and a movable rotating screw 12 as a movable screw, the spacing between the movable rotating screw 12 and the fixed rotating screw 11 is adjusted during the movement, thereby changing the rotational force of the movable rotating screw 12. After having the driving force, the movable rotating screw 12 rotates the connecting gear on the housing 1 through the second gear 15, and the multiple connecting gears are engaged with each other and rotated, so that the gear 10 on the rotating shaft 9 is rotated, and the rotation of the gear 10 drives the rotating shaft 9 to rotate, thereby realizing transmission with other objects.
