Description

Technical Field

[0001] The invention relates to the field of machinery, in particular to a fluid pump. Background Art

[0002] Existing fluid pumps use pistons, impellers, and screws as fluid propulsion devices.

[0003] Fluid propulsion devices with impeller, screw and other structures have "profile" design requirements, and profile parameters need to be set comprehensively according to different properties, flow rates and pressures of the fluid. It is difficult to adapt to various fluid states and is easily damaged by impurities.

[0004] Although the traditional piston has more universal applicability, the traditional piston adopts the form of tightly extruding the piston ring, which has large running resistance and is easy to wear, resulting in a short service life and frequent replacement. In addition, the processing technology is complicated, and the cylinder (piston cylinder) suitable for long-stroke operation of the piston is difficult to process. The piston cylinder with a length greater than 2m is almost impossible to achieve.

[0005] The piston moves back and forth during operation, so in order to reduce the energy consumed in the direction change process, the weight of the piston is often reduced in the design. As a result, more complex structural settings are not allowed, limiting performance.

[0006] Traditional piston cylinders and pistons have high requirements for the purity of the flowing fluid when in use. If there are a lot of impurities, the impurities will squeeze into the sealing surface, causing accelerated wear of internal components. In actual use, it is often necessary to filter and purify the flowing fluid or to have high requirements for the cleanliness and tidiness of the inner wall of the cylinder, which has the defect of high maintenance cost. Summary of the invention

[0007] The object of the invention is to provide a fluid pump driving device to solve at least one of the above-mentioned technical problems.

[0008] The technical problem solved by the invention can be achieved by adopting the following technical solutions:

[0009] A fluid pump driving device, comprising a fluid driving mechanism allowing fluid to be driven in a pipeline, characterized in that:

[0010] The fluid pushing mechanism is provided with a fluid blocking mechanism for pushing the fluid;

[0011] The fluid propulsion mechanism is also provided with at least two rolling components supporting the fluid propulsion mechanism, and the rolling components are at least one of balls, rollers and rollers.

[0012] During operation, at least two rolling components abut against the inner wall of the pipe, support the fluid pushing mechanism, and convert at least a portion of the sliding friction of at least one side of the fluid pushing mechanism into rolling friction. When the rolling components are balls, ball bearings and top ball bearings can be used.

[0013] The "fluid pump driving device" described above is suitable for operation in a pipeline, but the pipeline is not in the defined structure. The pipeline is not an essential technical feature and is not included in the mechanical structure of the "fluid pump driving device".

[0014] The conversion of sliding friction into rolling friction through rolling elements allows the fluid-driven mechanism to operate at much higher speeds.

[0015] And even if it runs at a higher speed, it will not cause much wear on the contact parts. Mechanically, it has better reliability and a much longer service life.

[0016] In summary, the operating speed and efficiency of the equipment can be improved, the failure rate of the equipment can be reduced, and the service life of the equipment can be greatly extended.

[0017] The fluid driving mechanism of the present invention is essentially different from the traditional piston.

[0018] The traditional piston pump piston or cylinder piston is required to withstand strong instantaneous high pressure, so the technical design adopted is to withstand high pressure, have strong sealing and not too high movement speed.

[0019] The average operating speed of a conventional piston pump piston or cylinder piston is generally less than 3 meters per second.

[0020] The provision of rolling parts on the conventional piston pump piston or cylinder piston cannot reduce the friction of the "piston ring" with high sealing strength. Therefore, the conventional piston is not suitable for the design of the present invention.

[0021] The design of the present invention is not to withstand instantaneous high pressure, but to adapt to the operating environment where the sealing is not too high, the pressure difference is not too large, and the operating speed is continuously high. The design requirement of the present invention is to allow the speed to be above 10 meters per second, and even reach a speed of more than 40 meters per second. It is essentially different from the traditional piston design.

[0022] This technical requirement was encountered by the inventor of the present invention when carrying out other original designs.

[0023] In the present invention, the friction of the sealing mechanism (fluid blocking mechanism for pushing the fluid) is not high by allowing the sealing performance to be reduced and the pressure difference to be reduced. After the fluid pushing mechanism is supported by the rolling component, the friction can be further reduced. By reducing the sliding friction, the technical advantage of continuous high-speed operation is obtained.

[0024] In summary, the inventor of the present invention not only creatively opened up a technical demand, but also overcame the prejudice of the existing technology and designed a fluid propulsion mechanism that reduces sealing and pressure difference but has the outstanding technical advantage of continuous high-speed operation.

[0025] Many of the following designs are designed to adapt to continuous high-speed unidirectional operation, a technical requirement that previous piston technology has never encountered.

[0026] The driving mode of the fluid driving mechanism is magnetic drive.

[0027] Magnetic drive methods include:

[0028] (1) Type 1:

[0029] The fluid pushing mechanism is provided with a member having magnetic force including at least one of a permanent magnet, a soft magnet and an electromagnet;

[0030] An external magnetic coupling system is provided outside the pipeline;

[0031] The fluid driving mechanism is magnetically coupled to the external magnetic coupling system and isolated by a pipeline.

[0032] The external magnetic coupling system is provided with a rolling component for supporting on the outer wall of the pipe to avoid sliding friction and isolate impact. The external magnetic coupling system is used in conjunction with the fluid pump driving device.

[0033] The external magnetic coupling system is driven by an electric motor, thereby driving the fluid to propel the mechanism to move.

[0034] (2) The second type:

[0035] The fluid pushing mechanism is provided with a member having magnetic force including at least one of a permanent magnet, a soft magnet and an electromagnet;

[0036] At least two electromagnetic induction coils are arranged on the pipeline;

[0037] It also includes an electromagnetic induction coil control circuit, which controls and connects at least two electromagnetic induction coils;

[0038] By energizing different electromagnetic induction coils, magnetic fields are generated in turn, and magnetic forces are generated through the magnetic fields and the fluid propulsion mechanism, and the fluid propulsion mechanism is driven by the magnetic force.

[0039] Specific implementation of fluid propulsion mechanism:

[0040] The fluid driving mechanism in the fluid pump driving device includes at least one curved structure with a curvature that fits the inner wall of the pipeline.

[0041] The bending structure matches the bending degree of the inner wall of the pipe, which reduces the steering resistance, improves the combination accuracy with the inner wall of the pipe, and improves the sealing performance.

[0042] For example, the pipeline is bent into an arc shape or a circle, and the fluid pushing mechanism has a curved structure with an arc equivalent to the radius of the circle.

[0043] Preferably, the total length of the curved structure is at least 1.5 times the diameter.

[0044] Improve stability during rotation, reduce vibration, and improve sealing by extending the length without increasing resistance.

[0045] At least two rollers arranged front and back are provided on one side of the fluid pushing mechanism away from the center of the pipe to bear the centrifugal force caused during the rotation process.

[0046] At least two rollers arranged front and back bear the main pressure of the fluid pushing mechanism. At least two rollers arranged front and back evenly share the pressure, which leads to lower pressure, better protection of the inner wall of the pipeline and more stable operation.

[0047] The other side of the fluid-driven mechanism may use ball bearings.

[0048] The pressure on the other side of the fluid driving mechanism is relatively small, and the use of ball bearings can simplify the structure and reduce the weight.

[0049] Compared with the idea of ​​reducing the weight of the piston as much as possible in order to reduce the energy consumed in the up and down direction conversion process in the piston design, the present invention allows the fluid propulsion mechanism to have a higher mass (weight) and allows for a more complex structural setting, thereby improving performance.

[0050] The fluid pushing mechanism is provided with at least one sealing ring with elastic force that expands outwards; the gap between the sealing ring and the inner wall of the pipeline is reduced by the sealing ring.

[0051] Furthermore, the fluid pushing mechanism is provided with a groove, the sealing ring is embedded in the groove, and the outer edge protrudes from the groove, and the sealing ring is provided with an opening, and the opening provides space conditions for elastic compression and expansion.

[0052] The axial direction of the sealing ring is consistent with the forward direction of the magnet, and can also be appropriately tilted to improve the airtight effect.

[0053] The sealing ring is preferably a metal ring, a Teflon material ring, a metal and plastic composite structure ring, or other wear-resistant elastic material ring. The metal ring can be made of stainless steel with stable performance or memory alloy with good wear resistance; the Teflon material can make the sealing ring corrosion-resistant and moisture-resistant; the composite structure of metal and plastic can effectively reduce costs.

[0054] The fluid driving mechanism is a magnet mechanism provided with magnets, and the magnet mechanism is provided with magnets on at least two opposite sides;

[0055] Through the magnetic mechanism, magnetic contact is established with the device installed outside the pipeline to output signals or energy.

[0056] The magnets on both sides facilitate magnetic balance and increase the magnetic force.

[0057] In addition, the magnets on both sides can interact with the magnetic device outside the pipe to generate forces in opposite directions on both sides, so that the forces in two directions on the magnetic mechanism can offset each other and reduce friction.

[0058] Furthermore, magnets are arranged on two opposite sides of the magnet mechanism and on another side, that is, magnets are arranged on three sides.

[0059] In order to balance the magnetic force and increase the magnetic force.

[0060] Furthermore, at least two grooves are provided on the fluid driving mechanism, and at least two sealing rings with openings are respectively embedded in the at least two grooves, and the outer edges protrude from the grooves.

[0061] In order to make the sealing ring have expansion elasticity, an opening is set, but the opening is not airtight. In order to solve the problem of airtightness, a method of staggering the opening angles of multiple sealing rings is adopted.

[0062] When the fluid flows through the at least two staggered openings, flow resistance is generated, thereby improving the sealing performance.

[0063] Both ends of the sealing ring are respectively provided with butt joints; at least one of the two butt joints is provided with a notch in the thickness.

[0064] The gap is arranged in thickness, rather than in radial direction (height). No matter how tightly the two butt ends are butted, the gap can be avoided in the length direction (flow direction) of the fluid pump driving device.

[0065] In the above design, the sealing ring has a larger rebound amplitude, smaller extrusion force and a larger allowable wear amplitude compared to the traditional piston ring.

[0066] As a result, the patented device has less resistance, less wear, lower requirements on fluid purity, and lower requirements on the cleanliness and neatness of the inner wall of the pipeline compared to the piston and piston cylinder.

[0067] The head is provided with at least one depression for the current collector.

[0068] The depressions cause turbulence and rebound of the fluid flow that impacts the depressions, thereby forming reverse turbulence, increasing the resistance of the fluid flow passing through the side surfaces, and improving the sealing performance.

[0069] Furthermore, at least one edge of the recess is less than 4 mm away from the edge of the fluid pushing mechanism, so that the turbulent flow and the fluid flow passing through the edge generate resistance, thereby improving the sealing performance and the thrust.

[0070] The depression is preferably a depression with a depth greater than 6 mm and a width greater than 5 mm, so as to ensure the turbulent quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] In order to make the technical means, creative features, objectives and effects of the invention easy to understand, the invention is further explained below with reference to specific diagrams.

[0086] Reference Figures 1 to 13 The fluid pump driving device includes a fluid driving mechanism 1 that allows the fluid to be driven in a pipeline 2, and a fluid blocking mechanism 10 for driving the fluid is arranged on the fluid driving mechanism 1; the fluid driving mechanism 1 is also provided with at least two rolling components that support the fluid driving mechanism 1, and the rolling components are at least one of a ball, a roller e, and a roller.

[0087] During operation, at least two rolling components abut against the inner wall of the pipe 2 to support the fluid propulsion mechanism 1, and convert at least a portion of the sliding friction of at least one side of the fluid propulsion mechanism 1 into rolling friction. When the rolling components are balls, top ball bearings can be used.

[0088] The above-mentioned "fluid pump driving device" is suitable for running in the pipeline 2, but the pipeline 2 is not in the defined structure. The pipeline 2 is not an essential technical feature and is not included in the mechanical structure of the "fluid pump driving device".

[0089] The sliding friction is converted into rolling friction by the rolling components, thereby allowing the fluid propulsion mechanism 1 to operate at a much higher speed.

[0090] And even if it runs at a higher speed, it will not cause much wear on the contact parts. Mechanically, it has better reliability and a much longer service life.

[0091] In summary, the operating speed and efficiency of the equipment can be improved, the failure rate of the equipment can be reduced, and the service life of the equipment can be greatly extended.

[0092] The fluid driving mechanism 1 in the present invention is essentially different from the traditional piston.

[0093] The traditional piston pump piston or cylinder piston is required to withstand strong instantaneous high pressure, so the technical design adopted is to withstand high pressure, have strong sealing and not too high movement speed.

[0094] The average operating speed of a conventional piston pump piston or cylinder piston is generally less than 3 meters per second.

[0095] The provision of rolling parts on the conventional piston pump piston or cylinder piston cannot reduce the friction of the "piston ring" with high sealing strength. Therefore, the conventional piston is not suitable for the design of the present invention.

[0096] The design of the present invention is not to withstand instantaneous high pressure, but to adapt to the operating environment where the sealing is not too high, the pressure difference is not too large, and the operating speed is continuously high. The design requirement of the present invention is to allow the speed to be above 10 meters per second, and even reach a speed of more than 40 meters per second. It is essentially different from the traditional piston design.

[0097] This technical requirement was encountered by the inventor of the present invention when carrying out other original designs.

[0098] In the present invention, the friction of the sealing mechanism (fluid blocking mechanism 10 for pushing the fluid) is not high by allowing the sealing performance to be reduced and the pressure difference to be reduced. After the fluid pushing mechanism 1 is supported by the rolling component, the friction can be further reduced. By reducing the sliding friction, the technical advantage of continuous high-speed operation is obtained.

[0099] In summary, the inventor of the present invention not only creatively opened up a technical demand, but also overcame the prejudice of the prior art and designed a fluid propulsion mechanism 1 that reduces sealing and pressure difference but has the outstanding technical advantage of continuous high-speed operation.

[0100] Many of the following designs are designed to adapt to continuous high-speed unidirectional operation, a technical requirement that previous piston technology has never encountered.

[0101] The driving mode of the fluid driving mechanism is magnetic drive.

[0102] Magnetic drive methods include:

[0103] (1) Type 1:

[0104] The fluid pushing mechanism is provided with a member having magnetic force including at least one of a permanent magnet, a soft magnet and an electromagnet;

[0105] An external magnetic coupling system is provided outside the pipeline;

[0106] The fluid driving mechanism is magnetically coupled to the external magnetic coupling system and isolated by a pipeline.

[0107] The external magnetic coupling system is provided with a rolling component for supporting on the outer wall of the pipe to avoid sliding friction and isolate impact. The external magnetic coupling system is used in conjunction with the fluid pump driving device.

[0108] The external magnetic coupling system is driven by an electric motor, thereby driving the fluid to propel the mechanism to move.

[0109] (2) The second type:

[0110] The fluid pushing mechanism is provided with a member having magnetic force including at least one of a permanent magnet, a soft magnet and an electromagnet;

[0111] At least two electromagnetic induction coils are arranged on the pipeline;

[0112] It also includes an electromagnetic induction coil control circuit, which controls and connects at least two electromagnetic induction coils;

[0113] By energizing different electromagnetic induction coils, magnetic fields are generated in turn, and magnetic forces are generated through the magnetic fields and the fluid propulsion mechanism, and the fluid propulsion mechanism is driven by the magnetic force.

[0114] Specific implementation of the fluid propulsion mechanism 1:

[0115] Reference Figure 2 , 5 , 6, 10, 11, the fluid propulsion mechanism 1 in the fluid pump propulsion device includes at least one section, which has a curved structure whose curvature fits the inner wall of the pipeline 2.

[0116] The curved structure matches the curvature of the inner wall of the pipe 2, thereby reducing the steering resistance, improving the combination accuracy with the inner wall of the pipe 2, and improving the sealing performance.

[0117] For example, the pipeline 2 is a curved pipeline 2 bent into an arc shape or a circle, and the fluid pushing mechanism 1 has a curved structure with a curvature equivalent to that of the pipeline 2 .

[0118] Preferably, the total length of the curved structure is at least 1.5 times the diameter.

[0119] Improve stability during rotation, reduce vibration, and improve sealing by extending the length without increasing resistance.

[0120] The fluid pushing mechanism 1 is provided with rolling parts at both ends, which are called the front rolling part and the rear rolling part. A roller is also provided between the front rolling part and the rear rolling part, which is called the middle rolling part.

[0121] The middle rolling component is arranged on a side of the fluid pushing mechanism 1 away from the center of the pipe 2;

[0122] Permanent magnets are arranged on one side, the upper side and the lower side of the fluid pushing mechanism 1 near the center of the pipeline 2 .

[0123] According to conventional design ideas, the roller is used to support the fluid propulsion mechanism 1 and offset the gravity. Gravity is a downward force, so the roller is set at the bottom in the design.

[0124] This patent, on the contrary, sets the roller on the side, which cannot support the fluid pushing mechanism 1 from below, and violates the traditional design idea. Setting the roller on the side is not a traditional way of use.

[0125] The significant technical effects of the above design are:

[0126] The fluid propulsion mechanism 1 has a curved structure, and the center of gravity of the fluid propulsion mechanism 1 is biased toward the side away from the center of the pipe 2, which will cause a torsion force that causes the middle of the fluid propulsion mechanism 1 to sink, or even cause the two ends to lift, but the middle part will rub against the pipe 2. If a rolling component is set below the middle part, it will affect the arrangement space of the permanent magnet.

[0127] In order to solve two technical problems at the same time, the inventor of this patent sets the roller on the side between the two ends, squeezes the inner wall of the pipe 2 (circular pipe or elliptical pipe) through the side wall of the roller, and uses the edge of the side wall of the roller (not the ball) and the curved inner wall of the pipe 2 (circular pipe or elliptical pipe) to achieve positioning (such as positioning in the up and down direction). Thus, the prior art bias is overcome and two technical problems are solved at the same time.

[0128] Two rollers arranged front and back are provided between the front rolling component and the rear rolling component.

[0129] It is ensured that at least two of the front rolling member, the rear rolling member, and the two middle rolling members keep in contact with the inner wall of the pipe when passing through the fluid inlet 6 and the fluid outlet 7. The two middle rolling members arranged in front and behind allow the fluid inlet 6 and the fluid outlet 7 to be set thicker to ensure fluid circulation.

[0130] At least two rollers e arranged front and back are provided on one side of the fluid pushing mechanism 1 away from the center of the pipe 2 to withstand the centrifugal force caused during the rotation process.

[0131] At least two rollers e arranged front and back bear the main pressure of the fluid pushing mechanism 1. At least two rollers e arranged front and back make the pressure evenly distributed, the pressure is lower, the inner wall of the pipeline 2 is better protected, and the operation is more stable.

[0132] The other side of the fluid driving mechanism 1 may use ball bearings.

[0133] The pressure on the other side of the fluid driving mechanism 1 is relatively small, and the use of ball bearings can simplify the structure and reduce the weight.

[0134] Compared with the piston design, in order to reduce the energy consumed in the up and down direction conversion process, the idea of ​​reducing the weight of the piston as much as possible, the present invention allows the fluid propulsion mechanism 1 to have a higher mass (weight), allowing a more complex structural setting, thereby improving performance.

[0135] The fluid pushing mechanism 1 is provided with at least one sealing ring 11 with elastic force to expand outwards; the sealing ring 11 reduces the gap between the fluid pushing mechanism 1 and the inner wall of the pipe 2 .

[0136] Furthermore, the fluid pushing mechanism 1 is provided with a groove, the sealing ring 11 is embedded in the groove, and the outer edge protrudes from the groove, and the sealing ring 11 is provided with an opening. The opening provides space conditions for elastic compression and expansion.

[0137] The axial direction of the sealing ring 11 is consistent with the advancing direction of the magnet, and can also be appropriately tilted to improve the airtight effect.

[0138] The sealing ring 11 is preferably a metal ring, a Teflon material ring, a metal and plastic composite structure ring, or other wear-resistant elastic material ring. The metal ring can be made of stainless steel with stable performance or memory alloy with good wear resistance; the Teflon material can make the sealing ring 11 corrosion-resistant and moisture-resistant; the composite structure of metal and plastic can effectively reduce costs.

[0139] The fluid driving mechanism 1 is a magnet mechanism provided with magnets, and magnets are provided on at least two opposite sides of the magnet mechanism;

[0140] Through the magnet mechanism, magnetic connection is established with the device arranged outside the pipeline 2 to output signals or energy.

[0141] The magnets on both sides facilitate magnetic balance and increase the magnetic force.

[0142] In addition, the magnets on both sides can interact with the magnetic device outside the pipe 2 to generate forces in opposite directions on both sides, so that the forces in two directions received by the magnetic mechanism can cancel each other out and reduce friction.

[0143] Furthermore, magnets are arranged on two opposite sides of the magnet mechanism and on another side, that is, magnets are arranged on three sides.

[0144] In order to balance the magnetic force and increase the magnetic force.

[0145] Furthermore, at least two grooves are provided on the fluid driving mechanism 1, and at least two sealing rings 11 with openings are respectively embedded in the at least two grooves, and the outer edges protrude from the grooves.

[0146] In order to make the sealing ring 11 have expansion elasticity, an opening is provided, but the opening is not airtight. In order to solve the problem of airtightness, a plurality of sealing rings 11 are provided with staggered opening angles.

[0147] When the fluid flows through the at least two staggered openings, flow resistance is generated, thereby improving the sealing performance.

[0148] Both ends of the sealing ring 11 are respectively provided with butt ends c1 ; at least one of the two butt ends c1 is provided with a notch in the thickness.

[0149] The notch is arranged in the thickness, rather than in the radial direction (height). No matter how tightly the two butt ends c1 are butted, the notch can be avoided in the length direction (flow direction) of the fluid pump driving device.

[0150] In the above design, the sealing ring 11 has a larger rebound amplitude, a smaller extrusion force, and a larger allowable wear amplitude compared to a traditional piston ring.

[0151] As a result, the patent has less resistance, less wear, lower requirements on the purity of the fluid, and lower requirements on the cleanliness and neatness of the inner wall of the pipeline 2 compared to the piston and the piston cylinder.

[0152] The head 3 is provided with at least one recess for the current collector.

[0153] The depressions cause turbulence and rebound of the fluid flow that impacts the depressions, thereby forming reverse turbulence, increasing the resistance of the fluid flow passing through the side surfaces, and improving the sealing performance.

[0154] Furthermore, at least one edge of the recess is less than 4 mm away from the edge of the fluid pushing mechanism 1, so that the turbulent flow and the fluid flow passing through the edge generate resistance, thereby improving the sealing performance and thrust.

[0155] The depression is preferably a depression with a depth greater than 6 mm and a width greater than 5 mm, so as to ensure the turbulent quality.

[0156] The head is provided with a protrusion in the forward direction;

[0157] The height of the front end of the protrusion is not higher than one third of the height of the valve 5 .

[0158] Therefore, when the fluid pump pushes the door body of the valve 5, the protrusion first pushes the free end side of the door body, so that the fluid pump pushes the door body with less force, making the door open smoothly and reliably.

[0159] Specific implementation of the fluid blocking mechanism 10:

[0160] Reference Figure 2 , 5 , 6, 10, 11, the fluid blocking mechanism 10 is provided with at least one annular recess, a sealing ring 11 is embedded in the annular recess, and at least a part of the sealing ring 11 protrudes outside the annular recess.

[0161] The sealing ring 11 is pressed against the inner wall of the pipe 2 to improve the sealing performance.

[0162] The outer layer of the sealing ring 11 is made of plastic material.

[0163] The sealing ring 11 in the present invention is essentially different from the conventional piston pump piston.

[0164] The piston of a conventional piston pump is required to withstand strong instantaneous high pressure, so the piston ring is made of hard metal. The above design of the present invention is not used to withstand instantaneous high pressure, but to operate in an environment with relatively low pressure but continuous high speed operation.

[0165] In view of the relatively low pressure but continuous high-speed operation environment, the seal ring 11 with a plastic outer ring has good wear resistance, is conducive to protecting the inner wall of the pipe 2, and has the characteristics of low friction. Furthermore, because the plastic material has better elasticity, the processing accuracy requirements for the pipe 2 can be lower, making it simple and feasible to process a pipe 2 that is several meters long or even more than ten meters long.

[0166] The outer layer of the sealing ring 11 is made of a plastic material, and the plastic material ring is preferably at least one of a polytetrafluoroethylene ring and a nitrile rubber ring.

[0167] Reference Fig.14 The sealing ring 11 has a flexible opening portion facing the side, and the opening of the opening portion faces the high-pressure side of the fluid blocking mechanism 10.

[0168] The opening of the opening portion may be such that at least a portion thereof protrudes outside the annular recess.

[0169] Alternatively, the interior of the opening portion is communicated with the exterior of the opening.

[0170] The high-pressure fluid generates pressure on the opening portion, thereby causing the opening to open, so that the edge of the opening portion abuts against the inner wall of the pipe 2.

[0171] Because the opening is opened by fluid pressure in the above design, the sealing performance and friction force will be different according to the different air pressures. This is a dynamic adjustment, which can make the operation smoother.

[0172] Furthermore, because the opening is opened by fluid pressure in the above-mentioned design, after the outer edge of the sealing ring 11 is worn, the opening has the potential to further expand to make up for the worn portion.

[0173] The opening is pushed open by air pressure, which has lower expansion force, lower friction, larger expansion space and longer service life compared to the structure that simply compensates for wear by material elasticity.

[0174] The fluid blocking mechanism 10 has a thickness, and is provided with at least two annular recesses in the thickness direction. At least two sealing rings 11 are respectively embedded in the two annular recesses.

[0175] At least two levels of sealing are achieved.

[0176] The front and rear ends of the fluid pushing mechanism 1 are respectively provided with fluid blocking mechanisms 10 for pushing the fluid. Each fluid blocking mechanism 10 is arranged with at least two annular recesses in the thickness direction, and at least two sealing rings 11 are respectively embedded in the two annular recesses.

[0177] The sealing is performed by at least four layers of sealing rings 11. This allows for a better sealing effect with lower friction. The fluid pushing mechanism 1 is provided with a magnet mechanism between the two fluid blocking mechanisms 10.

[0178] The fluid blocking mechanism 10 has a thickness greater than 2 cm, and the outer contour of the portion having the thickness is in close conformity with the contour of the inner wall of the pipe 2, and the distance is less than 1 mm.

[0179] By reducing the pressure difference layer by layer, utilizing the thickness and gap of the fluid blocking mechanism 10 and utilizing the viscosity of the fluid to achieve sealing, the friction force is further reduced while ensuring the sealing effect.

[0180] The pipe 2 is a pipe 2 with an arc, and the fluid blocking mechanism 10 has a portion with thickness, and has a structure in which the arc of the curvature fits the arc of the inner wall of the pipe 2 .

[0181] The fluid driving mechanism 1 is allowed to operate in a curved pipe 2 .

[0182] The conventional piston pump piston or cylinder piston does not operate in a curved piston cylinder and does not meet the above design requirements.

[0183] This technical requirement was encountered by the inventor of the present invention when carrying out other original designs.

[0184] Furthermore, the pipeline 2 is a pipeline 2 with a curvature, and the fluid pushing mechanism 1 is a structure in which the curvature fits the curvature of the inner wall of the pipeline 2.

[0185] The fluid driving mechanism 1 can run smoothly in the complete pipeline 2 .

[0186] The fluid propulsion mechanism 1 is provided with at least four rolling components, and at least four rolling components support at least one side of the fluid propulsion mechanism 1 in the pipeline 2 .

[0187] Keep one side of the fluid pushing mechanism 1 away from the inner wall of the pipe 2.

[0188] The inventor of the present invention encountered the design requirement of single-sided magnetic coupling when carrying out other original designs. In the state of single-sided magnetic coupling and high-speed circular motion, there will be a state where one side of the fluid driving mechanism 1 is under pressure.

[0189] In the above design, only one side of the fluid propulsion mechanism 1 is supported, which can achieve the effect of reducing the sliding friction as a whole.

[0190] Furthermore, three rolling components are respectively arranged around the two ends of the fluid driving mechanism 1 .

[0191] The three-point support in the pipeline 2 is used to provide support in all directions.

[0192] The invention has the advantages of simple structure, strong stability, low requirements on the processing accuracy of the inner wall of the pipeline 2, etc.

[0193] Specific implementation of the scrolling component:

[0194] Reference Fig.10 , 11 , 12, 13 When the rolling component adopts the roller e, the roller e adopts an outer edge with an outwardly protruding arc surface structure; the arc surface structure of the outer edge fits with the arc surface of the inner wall of the pipe 2 that needs to be adapted.

[0195] For example, if the radius of the arc section of the portion of the inner wall of the pipe 2 that is pressed against is 10 cm, then the radius of the arc section of the outer edge of the roller e is close to or even equal to 10 cm, so that the two can fit together.

[0196] When in use, the arc surface structure of the outer edge abuts against the inner wall of the pipe 2 to be adapted.

[0197] The use of the curved surface structure can greatly increase the contact area between the roller e and the inner wall of the pipe 2, thereby greatly reducing the pressure and further protecting the roller e and the pipe 2.

[0198] During the long-term operation of the device, the pressure deformation or wear deformation of the roller e and the pipeline 2 can be avoided. The device can operate stably for a much longer period of time.

[0199] In addition, because of the larger contact surface, even if there are small depressions or protrusions on the roller e and the pipe 2, it will not cause large operating fluctuations of the roller e, so that the equipment can run more smoothly. It has stronger fault tolerance and allows the difficulty of the processing technology to be appropriately reduced.

[0200] The roller e comprises a metal bearing and a wear-resistant plastic layer e1 wrapped around the outer ring of the metal bearing; the wear-resistant plastic layer e1 has an outer edge with an outwardly protruding arc surface structure; the arc surface structure of the outer edge fits with the arc surface of the inner wall of the pipe 2 to be adapted.

[0201] The wear-resistant plastic layer e1 is preferably made of at least one of polytetrafluoroethylene, nitrile rubber, and rubber.

[0202] At least one side of the wear-resistant plastic layer e1 is provided with a retaining spring groove e3. The wear-resistant plastic layer e1 is sleeved on the outer ring of the metal bearing, and the retaining spring is embedded in the retaining spring groove e3, thereby achieving fixation between the wear-resistant plastic layer e1 and the metal bearing.

[0203] Compared with bonding, bolting, vulcanization and other methods, this structure is firstly more firmly fixed, secondly, has stronger shock resistance, thirdly, it does not completely lock the two, allowing for appropriate slippage and buffering capacity, and fourthly, has a longer service life.

[0204] The fluid propulsion mechanism 1 is provided with a roller assembly, and the roller assembly is provided with at least one shaft hole;

[0205] The rotating shaft of roller e is inserted into the shaft hole;

[0206] A groove e2 is provided in the shaft hole;

[0207] An elastic pad e4 is arranged in the groove e2, and the elastic pad e4 abuts against the rotating shaft;

[0208] The rotating shaft is at least on one side of the elastic pad e4 and is away from the inner wall of the shaft hole.

[0209] The elastic pad e4 prevents at least one side of the rotating shaft from pressing the shaft hole, providing elastic activity space, and allowing the roller e to have floating space.

[0210] This design, applied in the system of the present invention, runs in the pipe 2. Compared with traditional spring, hydraulic and other shock-absorbing systems, it has the characteristics of simpler structure, lower cost, higher reliability, easier to set elastic effect and more stability.

[0211] The elastic pad e4 is an elastic pad made of plastic material.

[0212] For example, it is made of polytetrafluoroethylene, rubber, nitrile rubber, and other plastic materials.

[0213] Furthermore, the groove e2 is an annular groove e2, and an annular elastic pad e4 is arranged in the annular groove e2, and the annular elastic pad e4 abuts against the rotating shaft;

[0214] At least one side of the rotating shaft leaves the inner wall of the shaft hole, so as to realize multi-directional floating.

[0215] The roller e runs in the pipe 2, and has different running rules than the traditional one running on the plane. The traditional shock-absorbing system is only good at achieving shock absorption in one dimension and is difficult to adapt to the round pipe 2.

[0216] The above-mentioned design of the present invention can realize multi-directional floating and can adapt to the forces or deformations of the circular tube 2 from different dimensions.

[0217] At least one side of at least one of the shaft hole and the rotating shaft is provided with a retaining spring groove, and the shaft hole and the rotating shaft are fixed by the retaining spring.

[0218] Compared with bolt fixing, riveting fixing and other methods, firstly, the fixation is more firm, secondly, the earthquake resistance is stronger, and thirdly, the service life is longer.

[0219] The outer edge of the roller e has an elastic surface.

[0220] The elastic surface of the outer edge of the roller e automatically completes the fitting when it is pressed onto the inner wall of the pipe 2 , and can adapt to the irregularities caused by defects on the inner wall of the pipe 2 .

[0221] The contact area between the outer edge of roller e and the inner wall of pipe 2 is greatly increased compared with the contact area of ​​roller e with a ball or a cylindrical outer edge, thereby greatly reducing the pressure generated on the inner wall of pipe 2 and protecting the inner wall of pipe 2.

[0222] Furthermore, the width of the outer edge of the roller e is greater than one fifth of the radius of the roller e.

[0223] The contact area of ​​the abutting part is further ensured.

[0224] When the roller e rotates in the pipe 2, there is no need for turning, and there is no friction caused by turning.

[0225] The radius of the roller e is greater than one eighth of the width or diameter of the inner wall of the pipe 2 .

[0226] During the operation of the equipment, the roller E has a lower rotation speed. Although the weight is increased and the centrifugal force is increased, the bearing of the roller E is protected.

[0227] For equipment that is in working condition all year round, the stability is greatly improved.

[0228] The outer edge of the wheel body of the roller e is covered with an elastic wear-resistant material layer, which enhances the wear resistance of the wheel body of the roller e and prolongs its service life.

[0229] The wheel body can be made of metal or other hard materials, which ensures both strength and micro-elasticity.

[0230] The elastic wear-resistant material layer can be a rubber layer, polytetrafluoroethylene, etc. The use of a rubber layer with good elasticity and strong wear resistance or polytetrafluoroethylene with strong corrosion resistance can extend the service life.

[0231] The thickness of the elastic wear-resistant material layer is greater than 0.2 mm and less than 1.5 mm.

[0232] Avoid running deviations due to excessive wear during long-term operation. After the elastic wear-resistant material layer is completely worn away after a long period of operation, the system performance may be reduced, but it can still work relatively stably. There is enough time for after-sales service.

[0233] Alternatively, the wheel body of the roller e may be made of plastic material, preferably polytetrafluoroethylene, which has sufficient strength and slight elasticity.

[0234] Specific implementation of permanent magnet installation on fluid propulsion mechanism 1:

[0235] Reference Figure 5 , 6 , 7, 10, a fluid pump driving device, comprising a fluid driving mechanism 1, the fluid driving mechanism 1 is provided with a permanent magnet fixing structure, and the permanent magnet fixing structure is provided with at least two long permanent magnets a2;

[0236] It also includes at least three spacers a3, and the three spacers a3 are fixed in parallel on the permanent magnet fixing structure;

[0237] The long permanent magnet a2 is arranged between two parallel spacers a3, and two sides of the long permanent magnet a2 are respectively bonded to the two spacers a3.

[0238] In the traditional design, the bottom of the permanent magnet is bonded to the permanent magnet fixing structure. This design has the risk of pulling off. Therefore, in the traditional solution, a thin steel sleeve or a carbon fiber layer needs to be wrapped around the permanent magnet to make the permanent magnet firmly fixed.

[0239] The present invention particularly provides the following structure: the height of the spacer a3 is not less than half the thickness of the long permanent magnet a2, the long permanent magnet a2 is arranged between two parallel spacers a3, and the two sides of the long permanent magnet a2 are respectively bonded to the two spacers a3.

[0240] Compared with the conventional structure in which the bottom of the permanent magnet is bonded, this structure can withstand a much greater pulling force away from the permanent magnet fixing structure.

[0241] The same long permanent magnet a2, after adopting the structure of the present invention, can withstand a tensile force that is more than 3 times greater than that of the traditional design.

[0242] When the long permanent magnet a2 is subjected to a large magnetic pulling force, there is no need to add a thin steel sleeve or carbon fiber layer. The reduction of the thin steel sleeve or carbon fiber layer can reduce the cost and reduce the distance between the coupling magnets. In particular, reducing the distance between the coupling magnets is of great significance for obtaining a stronger magnetic coupling force.

[0243] Furthermore, the bottom of the long permanent magnet a2 is bonded to the permanent magnet fixing structure, and the two sides of the long permanent magnet a2 are bonded to the two spacers a3 on both sides.

[0244] Three-sided bonding is achieved to improve firmness. When using adhesives with reduced hardness such as epoxy resin, the three sides can also be buffered to protect the hard and brittle permanent magnets.

[0245] At least two long permanent magnets a2 are connected at their ends and arranged in an arc shape; at least two adjacent spacers a3 are arc-shaped spacers a3; at least two long permanent magnets a2 are arranged in an arc shape and sandwiched between two arc-shaped spacers a3.

[0246] The above design makes it possible to manufacture a permanent magnet arc with large volume, firm structure, low cost and easy installation.

[0247] The spacer a3 can be formed integrally on the fluid driving mechanism 1, and has the characteristics of simple structure and firm structure.

[0248] The spacer a3 may also be installed on the fluid driving mechanism 1 .

[0249] It is allowed that the spacer a3 and the fluid driving mechanism 1 are made of different materials.

[0250] Preferably, the permanent magnet fixing structure is made of aluminum alloy, and the spacer a3 is made of magnetic steel.

[0251] Aluminum alloy is used to reduce weight while ensuring mechanical strength. The spacer a3 is made of magnetic steel, which can optimize the magnetic field layout between two adjacent long permanent magnets a2.

[0252] Two adjacent long permanent magnets a2 can be arranged with like poles adjacent to each other, such as south poles adjacent to each other, so that the magnetic coupling force has a longer acting distance.

[0253] Reference Figure 7The separator a3 adopts at least a two-section structure, and the first separator and the second separator are connected by a splicing structure a4;

[0254] One end of the first spacer is clamped to a point on the fluid propulsion mechanism 1;

[0255] One end of the second spacer is clamped to another location on the fluid driving mechanism 1;

[0256] The first spacer and the second spacer are spliced ​​and fixed, so that the entire spacer a3 is fixed on the fluid driving mechanism 1.

[0257] This structure can avoid the use of bolts, and achieve indirect and firm fixation in a narrow space.

[0258] The splicing structure a4 adopted by the first and second spacers is that a socket is provided on the first spacer, and a plug matching the socket is provided on the second spacer;

[0259] The socket and the plug adopt a matching structure through side fitting and plugging;

[0260] The socket and the plug are plugged in by side fitting to form a structure that engages in the pulling direction.

[0261] The splicing structure a4 adopted by the first and second spacers is allowed to adopt a carpenter "falcon" structure, but is not limited to the "falcon" structure.

[0262] At least one end of the first spacer is clamped on a point on the fluid propulsion mechanism 1 in such a way that one end of the first spacer is hooked on the fluid propulsion mechanism 1 .

[0263] The above design makes it easy to design the structure of the entire spacer a3 on a plane, and to use a metal plate, adopt a plane cutting or cutting method, and manufacture it at a low cost, high efficiency, and easy to ensure precision.

[0264] A hook a5 is provided at one end of the first spacer, and a strip structure matching the hook a5 is provided on the fluid pushing mechanism 1, and the hook a5 of at least one spacer of ten spacers a3 is hooked on the strip structure.

[0265] The strip structure can be a groove or a concave edge.

[0266] The strip structure is advantageous for low-cost molding on one side. Compared with providing a matching component for each hook a5 of the first segment spacer, the cost is greatly reduced and the structure has a stronger fault tolerance, which facilitates mutual compensation of tolerances.

[0267] Going further:

[0268] The fluid pushing mechanism 1 is provided with a permanent magnet fixing structure having an arc surface;

[0269] The long permanent magnet a2 is an arc-shaped long permanent magnet;

[0270] The spacer a3 is a spacer a3 with an arc-shaped long strip structure.

[0271] This structure enables permanent magnets that are not round to be well fixed.

[0272] The fluid propulsion mechanism 1 can be a fluid propulsion mechanism 1 having a sealed structure and a pneumatic component that drives gas or liquid to operate.

[0273] Under the action of external force, the gas and liquid are driven and work is done on the gas and liquid.

[0274] On the fluid pushing mechanism 1, the thickness of the long permanent magnet a2 is preferably 1.8-2.5 mm, and the width is preferably 5-13 mm; the spacer a3 is made of magnetic steel, and the thickness is preferably 1.5-3 mm.

[0275] The above design has good magnetic field layout characteristics.

[0276] The magnetic steel can be carbon steel or other steel with a grade lower than 304.

[0277] The fluid pushing mechanism 1 adopts a bracket with a curved structure, and the permanent magnet fixing structure on the fluid pushing mechanism 1 has a curved arc surface.

[0278] This structure enables the "fluid pump driving device" to operate in the curved pipe 2, and facilitates the long permanent magnet a2 on the permanent magnet fixing structure to fit closer to the inner wall of the curved pipe 2 more fully.

[0279] The magnetic coupling has an inner component, and an outer component coupled to the inner component.

[0280] The fluid pushing mechanism 1 is provided with a rolling component for supporting on the inner wall of the pipe 2 to avoid sliding friction and isolate impact.

[0281] Specific implementation of external magnetic coupling system:

[0282] Reference Figure 8 , Fig. 9 The fluid pump driving device is magnetically coupled with the external magnetic coupling system and isolated by the pipe 2. The external magnetic coupling driving mechanism b1 is provided with a rolling component for supporting on the outer wall of the pipe 2. The sliding friction is avoided and the impact is isolated. The external magnetic coupling system is used in conjunction with the fluid pump driving device.

[0283] The external magnetic coupling system includes an external magnetic coupling propulsion mechanism b1 carrying a permanent magnet, wherein the external magnetic coupling propulsion mechanism b1 includes an external permanent magnet b2 fixing structure, and the external permanent magnet b2 is a long strip-shaped external permanent magnet b2 with an arc structure;

[0284] The external magnetic coupling propulsion mechanism b1 adopts an external permanent magnet b2 fixing structure with an arc-shaped concave surface;

[0285] The curvature of the arc-shaped structure of the outer permanent magnet b2 fits the curvature of the concave arc surface;

[0286] The arc surface is recessed at both ends of the external permanent magnet b2, and a convex structure b3 is respectively provided. The two convex structures b3 press against the two ends of the external permanent magnet b2 to form a fixation;

[0287] Baffles b4 are respectively arranged at both ends of the arc-surface depression, wherein at least one of the baffles b4 is a detachable baffle b4.

[0288] During assembly, each external permanent magnet b2 is inserted into the arc surface depression through the position of the removable baffle b4. During the insertion of the external permanent magnet b2, a magnetic conductive spacer with a matching shape can be inserted at intervals. After filling, the removable baffle b4 is installed. The external permanent magnet b2 is fixed from multiple directions.

[0289] This structure has an arched load-bearing property and can be well fixed even without using a large amount of adhesive.

[0290] The external magnetic coupling propulsion mechanism b1 is provided with a connecting component which is linked with the external linkage component, and the connecting component adopts a movable connection.

[0291] The external magnetic coupling propulsion mechanism b1 is allowed to wobble within a certain range, thus reducing the mechanical precision requirements.

[0292] The above-mentioned design of the present invention is applicable to the following technical environment:

[0293] Reference Figure 1 , a ring-type fluid pump, characterized in that it comprises a fluid pump driving device;

[0294] The fluid pump driving device comprises a fluid driving mechanism 1 that allows the fluid to be driven in the pipeline 2, and a fluid blocking mechanism 10 for driving the fluid is arranged on the fluid driving mechanism 1;

[0295] The fluid propulsion mechanism 1 is also provided with at least two rolling components supporting the fluid propulsion mechanism 1, and the rolling components are at least one of a ball, a roller, and a roller;

[0296] and an annular pipe 2 allowing the fluid pump driving device to circulate;

[0297] The fluid pushing mechanism 1 is provided with a member having magnetic force including at least one of a permanent magnet, a soft magnet and an electromagnet;

[0298] The pipeline 2 is connected to a fluid inlet 6 and a fluid outlet 7;

[0299] A valve 5 is provided between the fluid inlet 6 and the fluid outlet 7;

[0300] The valve 5 blocks the fluid at the fluid outlet 6 from flowing toward the fluid inlet 7 after closing, and is a valve 5 for controlling the flow of fluid;

[0301] The shape of the opening of the valve 5 in the on state is a shape that allows the fluid pushing mechanism 1 to pass through;

[0302] A motor is also provided;

[0303] The electric motor is provided with a driving device for driving the rotor to rotate;

[0304] The power output mechanism of the driving device is provided with a system provided with magnets which is linked with the fluid propulsion mechanism 1 through magnetic force, and is called an external magnetic coupling system.

[0305] When the fluid pushing mechanism 1 is located in front of the fluid inlet 6 and between the fluid inlet 6 and the fluid outlet 7 , the fluid pushing mechanism 1 is in a state of pushing the fluid that previously entered through the fluid inlet 6 to flow toward the fluid outlet 7 .

[0306] During use, fluid is introduced into the fluid inlet 6, and the annular pipe 2 is a channel for the fluid to flow;

[0307] The fluid, driven by the fluid driving mechanism 1, flows along the annular pipe 2 toward the fluid outlet 7;

[0308] During the movement of the fluid driving mechanism 1, the valve 5 is kept open by triggering the mechanical mechanism or the electric mechanism when the fluid driving mechanism 1 reaches the valve 5;

[0309] The fluid push mechanism 1 passes through the valve 5 and the fluid inlet 6, and then pushes the fluid to flow again, forming a cyclic movement process;

[0310] The motor drives the external magnetic coupling propulsion mechanism b1 of the external magnetic coupling system to move, thereby driving the fluid propulsion mechanism 1 to propel the fluid.

[0311] The front and rear in the present invention are based on the moving direction of the fluid propulsion mechanism 1. For example, the front of the fluid inlet 6 is the direction in which the fluid propulsion mechanism 1 continues to move after passing through the fluid inlet 6.

[0312] For example, the rear of the fluid inlet 6 is the opposite direction in which the fluid push mechanism 1 continues to move forward after passing (passing by) the fluid inlet 6. Then, the direction is established with a closer relationship, and the valve 5 is behind the fluid inlet 6.

[0313] Because there are no precise high-speed rotating or precisely meshing components such as blades, vortices, and screws, it allows impure fluids containing impurities to enter, and the requirements for fluid composition are greatly reduced compared to traditional equipment. The requirements for fluid quality are much lower than traditional equipment.

[0314] It is also allowed to increase the area of ​​the fluid inlet 6 to ensure a large flow rate and avoid impact while reducing the fluid flow rate. Moreover, because the flow rate is increased by expanding the fluid inlet 6, the fluid flow rate is reduced without consuming additional mechanical energy.

[0315] Because there is no "profile" design requirement for power components such as turbines, blades, screws, etc., the same device can be applied to different fluid parameter occasions and obtain good driving efficiency in unstable fluid supply occasions.

[0316] The pipeline 2 may be an annular pipeline 2. The annular pipeline 2 can be used to accumulate fluid, and has a stronger buffering capacity for high-pressure fluid and a stronger accumulation capacity for low-pressure fluid.

[0317] The ring shape is not limited to a standard circular ring structure. In addition to the circular ring structure, it can also be a ring shape of an elliptical structure, or a ring shape formed by a combination of some straight lines and circular arcs.

[0318] The pipeline 2 allows access to the valve 5 structure through a connecting section outside of the pipeline 2. The annular pipeline 2 may not be closed by itself, but is closed through other auxiliary components, so that the fluid pump driving device can be driven continuously.

[0319] The fluid pump driving device is different from the traditional piston. It does not reciprocate and does not need to be decelerated to switch to the reverse direction during operation. It allows continuous high-speed unidirectional movement, avoids energy loss during the switching process, and ensures continuous high-power energy output.

[0320] The above shows and describes the basic principles and main features of the invention and the advantages of the invention. Those skilled in the art should understand that the invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the invention. Without departing from the spirit and scope of the invention, the invention may have various changes and improvements, which fall within the scope of the invention to be protected. The scope of the invention to be protected is defined by the attached claims and their equivalents.
