Abstract
Description
Technical Field
[0001] The utility model relates to the field of machinery, in particular to a fluid device. Background Art
[0002] The existing driving systems mostly drive the driving device to make reciprocating motion in the pipeline through a connecting rod.
[0003] If the pipeline is a straight pipeline or a short pipeline with openings at both ends, and the driving device performs reciprocating motion, the connecting rod driving method is naturally acceptable. However, for a fluid pipeline with an arc, the driving device performs a circular motion, and the connecting rod is difficult to insert, this driving method is obviously not suitable. Utility Model Content
[0004] The purpose of the utility model is to provide a pipeline fluid driving system to solve the above technical problems.
[0005] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:
[0006] A pipeline fluid driving system, comprising a fluid pipeline and a driving device arranged in the fluid pipeline and moving along the fluid pipeline; characterized in that a conductive mechanism is arranged in the fluid pipeline;
[0007] The driving device is provided with a motor or a generator, and the power input end of the motor or the power output end of the generator is connected with a contact;
[0008] The contact is directly or indirectly movably connected to the conductive mechanism.
[0009] The utility model adds a conductive mechanism in the fluid pipeline, and uses the conductive mechanism to drive the motor to rotate, thereby driving the driving device to move in the fluid pipeline. Alternatively, the conductive mechanism is used to move the driving device so that the electric energy generated by the generator is transmitted to the outside of the fluid pipeline. The utility model uses electric energy instead of connecting rod drive, which can greatly increase the types of pipelines that the drive system can be applied to.
[0010] Preferably, the fluid pipeline is an airtight and annular fluid pipeline, and the driving device moves cyclically along the fluid pipeline in the fluid pipeline; a fluid inlet and a fluid outlet are opened on the side wall of the fluid pipeline, and an openable valve is arranged between the fluid inlet and the fluid outlet. After the valve is closed, it prevents the fluid at the fluid outlet from flowing to the fluid inlet, and is a valve for controlling the flow of fluid. Through the above design, the fluid moves from the fluid inlet to the fluid outlet and is discharged from the fluid outlet. The fluid inlet and the fluid outlet are opened on the side wall, and the driving device can rush through the valve and return to the fluid inlet again, thereby realizing cyclic movement.
[0011] Preferably, the driving device further comprises a rolling device, the rolling device is linked with the rotor of the motor, and the rolling device directly or indirectly abuts against the inner wall of the fluid pipeline. When the motor is an electric motor, electrical energy is transmitted to the motor through a conductive mechanism, causing the motor to rotate, and the rotor of the motor drives the rolling device to roll, thereby causing the driving device to move along the pipeline, thereby pushing the fluid forward. When the motor is a generator, the fluid drives the driving device to move along the pipeline, and at this time the rolling device rolls, thereby driving the rotor of the motor to rotate and generate electricity, and the electrical energy is transmitted out of the pipeline through the conductive mechanism.
[0012] Further preferably, the rolling device is at least one of a roller and a gear, and the roller or the gear is located on a side of the fluid pipeline away from the center, so that the rolling device can stably press against the pipeline wall with the help of the centrifugal force exerted on the driving device, thereby making the operation smooth.
[0013] Preferably, the conductive mechanism is at least two strip conductors arranged on the inner wall of the fluid pipeline, the strip conductors extend along the fluid pipeline, the strip conductors are connected to lead-out ends, one end of the lead-out end is located inside the fluid pipeline, and the other end of the lead-out end is located outside the fluid pipeline. The utility model selects the structure of the conductive mechanism, which is easy to install and has high stability.
[0014] Further preferably, at least one of the strip conductors is located on a side of the fluid pipeline away from the center, so that the contact of the driving device can be stably pressed against the strip conductor by means of the centrifugal force exerted on the driving device.
[0015] Preferably, the driving device further comprises a rolling device, and the conductive mechanism is at least two strip conductors arranged on the inner wall of the fluid pipeline;
[0016] The rolling device is a roller, and the roller abuts against the strip conductor;
[0017] Alternatively, the rolling device is a gear, and the strip conductor is provided with a rack meshing with the gear.
[0018] The rolling device is used as the contact or the contact is arranged on the rolling device, thereby simplifying the structure of the utility model.
[0019] Preferably, the driving device is provided with a sliding vane structure, and the sliding vane structure is in contact with the bottom of the fluid pipeline for at least 5 cm in the front-to-back direction. The sliding vane structure can effectively reduce vibration and make the operation smooth.
[0020] Further preferably, the slide structure is used as a contact or the contact is arranged on the slide structure, and the slide structure abuts against the conductive mechanism, thereby simplifying the structure of the utility model.
[0021] Preferably, the fluid pipeline adopts a non-rigid pipeline wall, and a hard support is provided outside the pipeline wall. The utility model adopts electric drive instead of connecting rod drive, so the circuit is allowed to be laid along the fluid pipeline and allowed to be bent, so the fluid pipeline of the utility model can be made of non-rigid materials. This is of great significance. The non-rigid pipeline wall makes the fluid pipeline have lower requirements for the applicable environment, which will greatly facilitate the promotion of the utility model.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.
[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The pipeline fluid driving system includes a fluid pipeline, a driving device 5 arranged in the fluid pipeline and moving along the fluid pipeline; a conductive mechanism is arranged in the fluid pipeline; a motor or a generator is arranged on the driving device 5, and a contact 10 is connected to the power input end of the motor or the power output end of the generator; the contact 10 is directly or indirectly connected to the conductive mechanism.
[0029] About Fluid Pipes
[0030] The fluid conduit of the utility model can be a straight conduit or a short conduit with openings at both ends, or it can be an arc-shaped conduit or an annular conduit. The fluid conduit is particularly preferably an airtight and annular fluid conduit, and the drive device 5 moves cyclically along the fluid conduit in the fluid conduit. At this time, a fluid inlet 1 and a fluid outlet 3 are opened on the side wall of the fluid conduit, and an openable valve is arranged between the fluid inlet 1 and the fluid outlet 3. After the valve is closed, the fluid at the fluid outlet 3 is prevented from flowing to the fluid inlet 1, and it is a valve for controlling the flow of fluid. Through the above design, the fluid moves from the fluid inlet 1 to the fluid outlet 3 and is discharged from the fluid outlet 3. The fluid inlet 1 and the fluid outlet 3 are opened on the side wall, and the drive device 5 can rush through the valve and return to the fluid inlet 1 again, thereby realizing the cyclic movement.
[0031] The utility model greatly reduces the requirements for the material of the fluid pipeline. It allows the fluid pipeline to use a non-rigid pipeline wall, and a hard support is provided outside the pipeline wall. In addition, the fluid pipeline of the utility model can be made of the following materials or structures:
[0032] The fluid pipeline is preferably an airtight, hard material pipeline. The pipeline wall of the fluid pipeline can be a single material structure or a combined material structure of metal, glass, ceramic, cement, sintered brick, glass fiber, plastic and the like. The pipeline wall is preferably a glass pipeline wall. The glass pipeline wall has the advantages of easy installation of optical sensing sensors, strong impact resistance, easy observation of internal operating status, easy fault detection, and corrosion resistance. It can be used in corrosive fluid environments.
[0033] The pipe wall is made of Teflon material. This kind of pipe wall has the advantages of easy molding, easy to set complex structure, low production cost, strong impact resistance and strong corrosion resistance.
[0034] Particularly preferably, the pipeline wall is made of at least one material of stainless steel and aluminum alloy that does not attract the permanent magnet. The pipeline wall of the fluid pipeline can adopt a pipeline wall of a composite structure, and the pipeline wall includes a wall body and an airtight, smooth, and hard adhesion layer attached to the inner wall of the wall body. When the volume of the fluid pipeline is relatively large, the whole body adopts a material with high airtightness, high smoothness, and high hardness, which will incur a large cost. In the above design, an adhesion layer structure is adopted, which allows the wall body to adopt a material with low cost to play a supporting and protective role, while a thinner adhesion layer can adopt a material with high cost, high airtightness, high smoothness, and high hardness. It is ensured that the drive device 5 runs in a high airtight environment with low friction, and the production cost is greatly reduced. The adhesion layer can adopt a pipeline wall of stainless steel, aluminum alloy, glass material, aluminum oxide material, or other materials with high airtightness, high smoothness, and high hardness. For the pipeline wall of the large fluid pipeline 3, it is preferably a pipeline wall of a composite structure.
[0035] Preferably, the pipe wall includes a wall body, the wall body is made of at least one material selected from glass fiber, plastic, ceramic, cement, and sintered brick; and a silicon dioxide material layer is attached to the wall body. Other chemical components are allowed to be added to the silicon dioxide material to improve performance. The silicon dioxide material layer can be an enamel layer or a glass layer. Further preferably, the pipe wall includes a wall body, the wall body includes a substrate composed of at least one of ceramic, cement, and sintered brick, a plastic layer is laid on the inner side of the substrate, and a glass layer is attached to the inner side of the plastic layer. The above-mentioned substrate is easy to shape as a whole to provide structural support and shaping that is convenient for on-site construction, the plastic layer provides an airtight layer that is resistant to aging and impact, and the glass layer provides an impact-resistant, low-friction contact surface. The substrate can provide high-strength structural support at low cost and low processing difficulty. The plastic layer is attached to the substrate, which is easy to shape. Because the plastic layer plays a buffering and airtight role, the glass layer can be allowed to no longer have airtightness, and the glass layer can be formed by relatively simple splicing of glass sheets during the manufacturing process. Under the premise of ensuring performance, the production difficulty and production cost are greatly reduced. The plastic layer is preferably a Teflon layer, and the glass layer is preferably a glass layer made of spliced tempered glass sheets. The pipe wall using the Teflon layer has the advantages of being easy to shape, easy to set up a complex structure, low production cost, strong impact resistance, strong corrosion resistance, etc. Moreover, the glass layer is a glass layer made of spliced tempered glass sheets, which is easier to fit to the complex structure of the Teflon layer. The above design not only solves the problem that large compression equipment is difficult to construct on site, but also reduces costs and ensures system performance.
[0036] The fluid pipeline can adopt a pipeline wall of an integral structure or a pipeline wall of a combined structure. The fluid pipeline includes two parts, one part is a lower tube body located below, and the other part is an upper tube body located above; the upper tube body is buckled downward on the upper part of the lower tube body, surrounding the pipeline cavity in the fluid pipeline. The split combined structure has the advantages of low manufacturing cost, simple installation, easy debugging, and easy maintenance when manufacturing large electric systems. In production, it can be that the pipeline wall of the lower tube body or the upper tube body is first produced, and then the material for generating the adhesion layer is coated in the pipeline wall, and then the adhesion layer generation process is carried out. For example, a glaze layer, a glass layer, or other layer generation materials are coated, and then sintered to generate a hard adhesion layer. In this process, because the structure of the lower tube body and the upper tube body is split, the coating work and the sintering work are greatly facilitated. In actual production, the fluid pipeline can naturally be disassembled into two parts on the left and right. However, this patent only adopts the method of disassembling up and down. This method can effectively ensure the smoothness and firmness of the bottom layer, thereby improving the operating performance and the compression efficiency.
[0037] The fluid pipeline can be an annular pipeline. The annular shape of the fluid pipeline is not limited to a standard circular ring structure. In addition to the circular ring structure, it can also be an elliptical ring structure, or a ring composed of a combination of some straight lines and circular arcs. The fluid pipeline allows access to the valve structure through a connecting section outside itself. The annular pipeline can be non-closed by itself, but it can be closed through other auxiliary components. The drive device 5 can move cyclically.
[0038] About Conductive Mechanism 3
[0039] The conductive mechanism 3 is at least two strip conductors arranged on the inner wall of the fluid pipeline, the strip conductors extend along the fluid pipeline, and the strip conductors are connected to lead-out ends, one end of the lead-out end is located inside the fluid pipeline, and the other end of the lead-out end is located outside the fluid pipeline. The utility model selects a structure of the conductive mechanism 3, which is easy to install and has high stability. Preferably, at least one of the strip conductors is located on a side of the fluid pipeline away from the center. Thereby, with the help of the centrifugal force exerted on the driving device 5, the contact 10 of the driving device 5 can be stably pressed on the strip conductor.
[0040] The conductive mechanism 3 is preferably a strip conductor disposed on the inner wall of the fluid pipeline. The strip conductor can be connected to the outside through an opening of the fluid inlet 1 and the fluid outlet 3 to input electrical energy to the outside. Avoid connecting to the outside through additional openings. The strip conductor can be a metal conductor strip, a metal plated strip, etc. disposed in the fluid pipeline, such as a copper conductor strip. The strip conductor extends along the inner wall of the fluid pipeline.
[0041] At least two strip conductors of the conductive mechanism 3 are arranged below the inner wall of the fluid pipeline; at least two contacts 10 respectively press the at least two strip conductors to achieve conduction. In the above design, the contact 10 and the strip conductor are pressed tightly by gravity, which has the characteristics of high stability and simple structure.
[0042] The number of strip conductors is preferably not less than the number of contacts 10, and preferably the number of strip conductors is equal to the number of contacts 10. At least two contacts 10 respectively press at least two strip conductors to achieve conduction, and the contacts 10 and the strip conductors are pressed tightly by gravity, which has the characteristics of high stability and simple structure.
[0043] At least two contacts 10 may be rolling contacts 10. Reduce friction and avoid wear. The rolling contact 10 may be at least one of a roller, a ball, and a roller. The contact 10 is arranged below the drive device 5. At least two contacts 10 may be rolling contacts. Reduce friction and avoid wear. The rolling contact may be at least one of a roller, a ball, and a roller.
[0044] For a straight pipe, the strip conductors are preferably arranged at equal intervals on the inner wall of the pipe. For an arc, circular or annular pipe, at least one strip conductor is located on the side wall away from the center, and at least one strip conductor is located on the side wall at the bottom.
[0045] About Rolling Device 6
[0046] The driving device 5 also includes a rolling device 6, which is linked to the rotor of the motor 4, and the rolling device 6 directly or indirectly presses against the inner wall of the fluid pipeline. When the motor 4 is an electric motor, the electric energy is transmitted to the motor through the conductive mechanism 3, so that the motor rotates, and the rotor of the motor drives the rolling device 6 to roll, so that the driving device 5 moves along the pipeline, thereby pushing the fluid forward. When the motor 4 is a generator, the fluid pushes the driving device 5 to move along the pipeline, and at this time, the rolling device 6 rolls, thereby driving the rotor of the motor to rotate and generate electricity, and the electric energy is transmitted out of the pipeline through the conductive mechanism 3.
[0047] The rolling device 6 is at least one of a roller and a gear, and the roller or the gear is located on a side of the fluid pipeline away from the center. Thus, with the help of the centrifugal force exerted on the driving device 5, the rolling device 6 can stably press against the pipeline wall, thereby making the operation smooth.
[0048] Alternatively, the rolling device 6 is a roller that abuts against the strip conductor; or the rolling device 6 is a gear, a rack meshing with the gear is provided on the strip conductor, and the rolling device 6 is used as a contact or the contact is provided on the rolling device 6. This simplifies the structure of the utility model.
[0049] The fluid pipeline has an arc, so the driving device 5 that moves along the inside of the fluid pipeline can only be made into an arc. However, the arc-shaped driving device 5 is difficult to manufacture, and once the arc of the driving device 5 is not completely consistent with the arc of the circulation pipeline, the driving device 5 is easy to touch the side wall of the circulation pipeline. If this happens for a long time, the driving device 5 or the circulation pipeline will be worn and damaged. The rolling device 6 itself has a certain shock absorption and smooth movement effect. The utility model preferably uses the rolling device 6 to elastically connect the driving device 5, for example, a shock absorber is provided at the connection. This further reduces shock and makes the movement smooth.
[0050] Alternatively, the drive device 5 is provided with a slide structure 7, and the slide structure 7 is in contact with the bottom of the fluid pipeline for at least 5 cm in the front-to-back direction. The slide structure 7 can effectively reduce vibration and make the operation smooth. Preferably, the slide structure 7 is used as a contact or the contact is arranged on the slide structure 7, and the slide structure 7 is against the conductive mechanism 3. This simplifies the structure of the utility model.
[0051] As shown in the drawings, a bracket 9 may be provided at each of the front and rear ends of the driving device, and the roller is connected to the bracket via a rotating shaft structure 8 .
[0052] About Motor
[0053] The motor is connected to the rolling device 6 through a speed change system to make the force smooth and reasonable. The contact can be set on the slide structure 7, and the contact point of the contact is below the slide mechanism to simplify the structure, reduce costs and improve stability.
[0054] The speed change system adopts a speed change system with an adjustable speed ratio. When the rolling device 6 exceeds the speed required for starting, the speed ratio is increased. During the starting process, the speed ratio is increased, the motor speed is reduced to reduce power or increase the speed. This design is conducive to reducing the thrust required for starting. In order to reduce the thrust required for starting, make the start smooth, and protect the internal stress-bearing parts.
[0055] A control circuit may be provided, and a sensor (which may be an optical sensor, a Hall sensor, etc.) for detecting the operating speed of the drive device 5 may be connected to the control circuit. When the sensor detects that the drive device 5 is lower than a set speed, the control circuit increases the speed ratio; when the sensor detects that the drive device 5 is higher than a set speed, the control circuit reduces the speed ratio. This is to automatically adjust the power output efficiency and the operating speed of the drive device 5 in a timely manner, so as to make the operation smooth, protect the internal force-bearing components, and improve the driving efficiency.
[0056] A track with resistance is provided on the inner wall of the fluid pipeline, and the rolling device 6 is against the track. By increasing the resistance, the rolling device 6 generates more force, generates more displacement, and thus completes more energy conversion. Specifically, preferably, the rolling device 6 uses a gear, and a rack meshing with the gear is provided on the inner wall of the fluid pipeline. The rack is used as a track. The meshing structure of the gear can withstand and output a greater force, and has the characteristics of high energy output.
[0057] The rack is arranged on the side wall inside the fluid pipeline. The arc structure of the fluid pipeline has a side close to the center of the fluid pipeline and a side away from the center of the fluid pipeline, both of which are side walls. Arranged on the side wall, it avoids the problem of different radii and tooth spacing on both sides of the rack due to the arc structure of the fluid pipeline. It also avoids the complexity of the gear needing to use a bevel gear.
[0058] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
