Pipeline power generation and flow regulation system

Abstract

The application provides a pipeline power generation and flow regulation system and relates to the technical field of valve well flow regulation. The inner wall of the rotating drum is provided with an overflow vane. The overflow vane is impacted by liquid in the rotating drum and drives the rotating drum to rotate, thereby driving the rotor connected with the rotating drum to rotate relative to the stator, converting kinetic energy into electric energy, and making the electric energy serve other electric objects in the pipeline valve well, such as a driving assembly, to realize stable power supply. When the flow needs to be adjusted, the driving force generated by the driving assembly drives the rotating drum and the adjusting cylinder to move along the axial direction, so that the adjusting cylinder can move relative to the flow guide cylinder. Since the adjusting cylinder is sleeved on the flow guide cylinder, the area of the flow guide hole is adjusted during the movement of the adjusting cylinder, thereby adjusting the liquid outflow area of the flow guide hole, realizing stable power generation and stable flow regulation, and relieving the technical problems that power supply of remote valve wells is difficult and stable operation of the adjusting facility cannot be guaranteed in the prior art.

Description

Technical Field

[0001] This invention relates to the field of valve well flow regulation technology, and in particular to a pipeline power generation flow regulation system. Background Technology

[0002] With the rapid advancement of water diversion projects, the scale of long-distance water diversion projects and large-scale irrigation district projects is constantly expanding. These projects are typically characterized by long water pipelines, numerous valve wells, and wide distribution, with most valve wells located in remote areas such as mountainous regions and ravines where transportation is inconvenient. As a critical node in the water transmission system, valve wells require various electrical equipment, including electric valves, remote terminal units (RTUs), various sensors, flow meters, and wireless communication modules, to achieve the monitoring, control, and data transmission functions of the water transmission system.

[0003] In existing technologies, the power supply for equipment within valve wells mainly employs three methods: wind power generation, solar power generation, and grid power supply. Wind power generation and solar power generation are renewable energy sources, but their power generation efficiency is significantly affected by natural environmental conditions. Since valve wells are often located in remote areas with complex terrain, these areas frequently suffer from unstable sunlight intensity and uneven wind resources, making it difficult to guarantee the continuity and reliability of power supply. While grid power supply offers higher stability, grid coverage is insufficient in remote areas, the cost of erecting power lines is high, and subsequent maintenance is difficult.

[0004] On the other hand, long-distance pressurized water pipelines typically require flow regulation and pressure control facilities at their ends to regulate pressure and distribute flow to different downstream water users. Traditional technology uses pressure-reducing and throttling flow regulation valves, which achieve regulation by consuming the kinetic energy of the water. This method not only results in significant waste of water energy, but its electric actuators also rely on external power supply. In remote areas where the power grid is difficult to cover, although wind-solar hybrid power supply can be used, the stability of the power supply cannot be guaranteed due to natural limitations, which poses a serious challenge to the remote automatic control of flow regulation valves. Summary of the Invention

[0005] The purpose of this invention is to provide a pipeline power generation and flow regulation system to alleviate the technical problems of power supply difficulties in remote valve wells and difficulty in ensuring the stable operation of regulation facilities in the prior art.

The adjusting tube is sleeved on the flow guide tube. The end of the flow guide tube away from the rotating drum is sealed, and a flow guide hole is provided on the side wall of the flow guide tube. The liquid in the flow guide tube flows out through the flow guide hole. The drive assembly is configured to generate a driving force acting on the rotating drum and the adjusting cylinder, the driving force being used to drive the rotating drum and the adjusting cylinder to move axially relative to the guide cylinder, thereby changing the area of ​​the adjusting cylinder that blocks the guide hole.

[0007] In an optional implementation, The flow control component also includes a flow guide cone; The guide cone is disposed on the sealing end face of the guide cylinder away from the rotating drum. The guide cone is hemispherical and is used to guide the liquid to the guide hole located laterally.

[0008] In an optional implementation, The pipeline power generation and flow regulation system also includes a first transition pipeline; The first transition pipe is located downstream of the rotating drum, the guide tube is located inside the first transition pipe, the outer wall of the guide tube is provided with a connecting part, and multiple connecting parts are spaced apart along the outer periphery of the guide tube, and multiple connecting parts are connected to the inner wall of the first transition pipe. The gap between any two adjacent connecting parts forms a liquid flow channel, and the liquid flowing out from the guide hole flows downstream along the liquid flow channel.

[0009] In an optional implementation, The drive assembly includes a first thrust rod and a first power tank; The first transition pipe has a first groove formed by an axial recess on the end face near the rotating drum. The first thrust rod is telescopically installed in the first groove. The end of the first thrust rod away from the rotating drum and the inner wall of the first groove form a first power cavity. The first power tank is connected to the first power cavity. The first power tank is used to deliver power medium to the first power cavity to drive the first thrust rod to push the rotating drum and the adjusting cylinder to move together relative to the first transition pipe.

[0010] In an optional implementation, An adjusting block is provided at the end of the adjusting cylinder away from the rotating drum, and a first bearing is provided between the adjusting block and the inner wall of the first transition pipe. The first bearing is used to enable the adjusting cylinder to rotate relative to the first transition pipe.

[0011] In an optional implementation, A second bearing is provided at the end of the first thrust rod near the rotating drum, and the second bearing is used to make the first thrust rod roll-connected with the rotating drum.

[0012] In an optional implementation, The pipeline power generation and flow regulation system also includes a second transition pipeline; The second transition pipe is disposed on the upstream side of the rotating drum, the second transition pipe is connected to the rotating drum, and the second transition pipe is configured to be movable relative to the rotating drum.

[0013] In an optional implementation, The drive assembly also includes a second thrust rod and a second power tank; The second transition pipe has a second groove formed by an axial recess on the end face near the rotating drum.

One end of the connecting cable is connected to the battery pack, and the other end of the connecting cable is connected to the stator through the junction box. The pipeline power generation and flow regulation system provided by this invention uses flow vanes installed on the inner wall of a rotating drum. These vanes, impacted by the liquid inside the drum, drive the drum to rotate, thereby causing a rotor connected to the drum to rotate relative to the stator. This converts kinetic energy into electrical energy, which is then used to power other electrical components within the pipeline valve well, such as drive components, achieving stable power supply. Furthermore, when flow adjustment is needed, the driving force generated by the drive components moves the rotating drum and regulating cylinder axially, allowing the regulating cylinder to move relative to the guide cylinder. Since the regulating cylinder is fitted onto the guide cylinder, the area of ​​the obstructed guide hole is adjusted during the cylinder's movement, thus regulating the liquid outflow area from the guide hole. This achieves stable power generation and flow regulation, alleviating the technical problems of power supply difficulties in remote valve wells and the inability to guarantee stable operation of regulation facilities in existing technologies.

Detailed Implementation

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] like Figures 1 to 8As shown, the pipeline power generation and flow regulation system provided in this embodiment integrates four major functions: energy harvesting, power conversion, local storage, and hydraulic regulation. The overall structure is arranged along the axial direction of the water transmission pipeline and can be directly embedded into the pipeline section in the existing valve well. It can operate autonomously for a long time without external power supply. Specifically, it includes a rotating drum 100, a first transition pipeline 200, an energy storage component 300, a flow regulation component 400, and a drive component. The rotating drum 100 is a hollow cylinder, and the inner wall of the rotating drum 100 is fixedly provided with flow vanes 120. When the water in the pipeline enters the interior of the rotating drum 100, the water flow continuously impacts the flow vanes 120, generating a rotational driving force around its own axis, thereby driving the entire rotating drum 100 to rotate stably.

[0024] The energy storage component 300 includes a stator 340 and a rotor 350. The rotor 350 is fixed to the circumferential position of the outer wall of the rotating drum 100 and rotates synchronously with the rotating drum 100. The stator 340 is relatively stationary in the external space of the rotating drum 100. The two form an electromagnetic induction structure. During the rotation of the rotor 350, the rotor cuts the magnetic field lines, causing the stator 340 to output electrical energy. The generated energy is rectified and regulated and then sent to the energy storage unit in the energy storage component 300 to provide a stable power source for the drive components required for subsequent current regulation.

[0025] The flow regulating component 400 includes a flow guide cylinder 410, one end of which is connected to the rotating drum 100 and the other end is closed. The side wall of the flow guide cylinder 410 is provided with multiple flow guide holes 411. An adjusting cylinder 110 is fixedly installed on the rotating drum 100. The adjusting cylinder 110 is sleeved on the outside of the flow guide cylinder 410 and fixedly connected to the rotating drum 100. The drive component acts on the rotating drum 100 and the adjusting cylinder 110 through a controllable axial thrust, so that the adjusting cylinder 110 is axially translated relative to the flow guide cylinder 410, thereby changing the coverage area of ​​the adjusting cylinder 110 on the flow guide holes 411, realizing continuous adjustment of the effective flow area of ​​the flow guide holes 411, and controlling the flow rate of the pipeline.

[0026] Based on the above, the flow regulating component 400 further includes a guide cone 420, which is disposed on the end face of the closed end of the guide cylinder 410. The overall outline of the guide cone 420 is hemispherical, and its curved surface faces the direction of incoming flow. When water flows through the interior of the guide cylinder 410 towards the closed end, the guide cone 420 smoothly guides the concentrated impact of the water flow to both sides along its surface and guides it to the guide hole 411 area located on the side wall of the guide cylinder 410, so that the water flow is more uniformly discharged from the guide hole 411, which not only avoids local loss, but also improves the stability and controllability of the outflow from the guide hole 411.

[0027] The pipeline power generation and flow regulation system also includes a first transition pipe 200, which is arranged downstream of the rotating drum 100. The guide cylinder 410 is fully housed inside the first transition pipe 200. The outer wall of the guide cylinder 410 is provided with multiple connecting parts 430 distributed circumferentially. Each connecting part 430 is fixedly connected to the inner wall of the first transition pipe 200, so that the guide cylinder 410 is stably supported on the central axis of the first transition pipe 200. An annular gap is naturally formed between any two adjacent connecting parts 430. This gap constitutes a liquid flow channel. The water flowing out from the guide hole 411 flows smoothly into the downstream main pipe along this flow channel, ensuring smooth flow of the entire system.

[0028] In a further optimized embodiment, the drive assembly includes a first thrust rod 510 and a first power tank 520. The inner wall of the first transition pipe 200 near the rotating drum 100 is axially recessed to form a first groove. The first thrust rod 510 is telescopically installed in the first groove, with its end away from the rotating drum 100 forming a first power cavity 530 with the inner wall of the groove. The first power tank 520 is connected to the first power cavity 530 via a pipeline, allowing the input of liquid or gaseous power media. The media pressure pushes the first thrust rod 510 outward, thereby transmitting the axial thrust sequentially to the rotating drum 100 and the regulating cylinder 110 fixed thereto, driving both to undergo controllable displacement relative to the guide cylinder 410 and the first transition pipe 200, thus executing the flow regulation action. This drive method does not rely on an external power source, utilizing only the water pressure within the pipe as a power source, converting kinetic energy into electrical energy to supply the drive device in the first power tank 520.

[0029] An adjusting block 111 is provided at the end of the adjusting cylinder 110 away from the rotating drum 100. A first bearing 10 is disposed between the outer peripheral surface of the adjusting block 111 and the inner wall of the first transition pipe 200. The first bearing 10 allows the adjusting cylinder 110 to maintain a rotational engagement with the first transition pipe 200 while moving axially, so that the rotating drum 100 can rotate freely. Furthermore, the first bearing 10 can be a sealed bearing to prevent water from flowing out in the gap between the adjusting block 111 and the first transition pipe 200.

[0030] In another structural refinement, a second bearing 20 is provided at one end of the first thrust rod 510 near the rotating drum 100. The second bearing 20 enables the first thrust rod 510 and the rotating drum 100 to form a rolling contact relationship, ensuring that the rotating drum 100 can rotate freely relative to the first thrust rod 510.

[0031] The pipeline power generation and flow regulation system is also equipped with a second transition pipe 600, which is located on the upstream side of the rotating drum 100 and communicates with the inner cavity of the rotating drum 100. The second transition pipe 600 can move relative to the rotating drum 100, so that the rotating drum 100 can move axially relative to the second transition pipe under the drive of the drive component.

[0032] The drive assembly also includes a second thrust rod 540 and a second power tank 550. The inner wall of the second transition pipe 600 near the rotating drum 100 is axially recessed to form a second groove. The second thrust rod 540 is telescopically installed in the second groove. The end of the second thrust rod 540 away from the rotating drum 100 and the inner wall of the groove enclose a second power chamber 560. The second power tank 550 is connected to the second power chamber 560 and is used to input power medium to drive the second thrust rod 540 to extend and retract. The second thrust rod 540 acts on the rotating drum 100 itself and can independently push the rotating drum 100 to move axially relative to the second transition pipe 600 when needed. This achieves axial displacement adjustment of the regulating cylinder 110 through the coordinated operation of the first and second thrust rods, thereby realizing flow regulation.

[0033] In further structural safeguards, a third bearing 30 is provided between the inner wall of the second transition pipe 600 and the rotating drum 100. The third bearing 30 supports the rotating drum 100 to achieve free rotation relative to the second transition pipe 600, ensuring the smooth start and stop and stable operation of the flow vane 120 under the action of water flow. Optionally, the third bearing 30 can be a sealed bearing to prevent water from flowing out from the gap between the second transition pipe 600 and the rotating drum 100.

[0034] The second thrust rod 540 is provided with a fourth bearing 40 at one end near the rotating drum 100, so that the second thrust rod 540 and the rotating drum 100 form a rolling connection, allowing the rotating drum 100 to rotate freely relative to the second thrust rod 540 along its own axis.

[0035] In terms of power management, the power storage component 300 includes a battery pack 310, a connecting cable 320, and a junction box 330. The junction box 330 is fixedly installed at the location of the stator 340, serving as the physical interface for power output; one end of the connecting cable 320 is connected to the charging and discharging port of the battery pack 310, and the other end is electrically connected to the output terminal of the stator 340 through the junction box 330, forming a complete power acquisition, rectification, and storage circuit.

[0036] In power generation mode, when liquid flows through the pipeline power generation and flow regulation system, the water flows into the interior of the rotating drum 100 and continuously impacts the flow vanes 120 fixed on its inner wall, thereby driving the rotating drum 100 to rotate stably around its own axis; the rotor 350 fixed on the outer wall of the rotating drum 100 rotates synchronously, and the rotor 350 and the stationary stator 340 form an electromagnetic induction structure, which causes the stator 340 to generate electrical energy during the relative motion; the generated electrical energy is rectified and regulated, and then transmitted to the battery pack 310 for storage through the connecting cable 320; this electrical energy is used to provide working power for the drive components and can also be used to supply other electrical equipment in the pipeline valve well.

[0037] In the flow regulation condition, the first thrust rod 510 in the drive assembly extends under the pressure of the first power tank 520 and the second thrust rod 540 extends under the pressure of the second power tank 550, pushing the rotating drum 100 and the regulating cylinder 110 fixed thereto to move axially downstream together. Since the regulating cylinder 110 is sleeved outside the guide cylinder 410 and the guide cylinder 410 has a guide hole 411 on its side wall, the axial displacement of the regulating cylinder 110 gradually covers the effective flow area of ​​the guide hole 411, thereby continuously reducing the flow area of ​​the guide hole 411. This process realizes the smooth and flexible regulation of the pipeline flow, and no external power supply is required throughout the process. It only relies on the electrical energy stored in the system itself to drive the actuator to complete the regulation action.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
