Description

Technical Field

[0001] This invention relates to the field of liquid medium power generation equipment technology, and in particular to a kinetic energy conversion structure and equipment based on pipeline hydraulic pressure. Background Technology

[0002] As humanity explores the world, abundant energy resources such as oil and natural gas in the ocean are gradually discovered, and people begin to exploit offshore oil and gas fields.

[0003] Due to the unique nature of the marine environment, crude oil extracted in shallow waters can be directly loaded onto oil tankers from production platforms. However, crude oil extracted in deep waters requires single-point mooring of large oil tankers to facilitate the safety of production platforms. To further facilitate the transportation of seabed oil, large-scale marine oil pipelines have been constructed to transport extracted oil directly to onshore oil depots. Valves are installed inside the pipelines to control the flow of marine oil.

[0004] However, because offshore oil pipelines are located deep on the seabed, it is not easy to install corresponding power generation equipment to supply electricity to the valves inside the pipeline, making it impossible to control the opening and closing of offshore oil transportation. Summary of the Invention

[0005] Therefore, it is necessary to provide a hydraulic kinetic energy conversion structure and device based on pipeline hydraulics, which is installed inside a liquid pipeline and converts kinetic energy into electrical energy according to the pressure of the liquid flow, and provides electrical power to the valves of the pipeline, in order to address the above-mentioned technical problems.

[0011] A support platform is fixedly installed on the support rod, and multiple blade assemblies are rotatably installed on the support platform. The blade assemblies are connected to a generator.

[0013] The support rod also has multiple guide holes for draining liquid from the water collector and the support platform.

[0014] In one embodiment, the radius of the water collector is greater than the length of the piezoelectric element, and the horizontal height of the water collector increases sequentially from the center to the edge.

[0015] In one embodiment, a fixed magnet is provided at the end of the piezoelectric sheet away from the support rod, and multiple brackets are provided at circumferential intervals around the outer ring of the water collector. A movable magnet is installed on the bracket, and the movable magnet corresponds one-to-one with the fixed magnet, and the magnetic poles of adjacent locations are the same.

[0016] In one embodiment, the movable magnet is movably mounted on the bracket by a spring, and the fixed magnet is fixedly mounted on the piezoelectric sheet.

[0017] In one embodiment, the flow-concentrating assembly includes a filter cover and a reservoir. One-way valves are respectively provided at both ends of the reservoir. The reservoir is installed at the top of the support rod, and the top of the reservoir is connected to the filter cover, while the bottom extends into the interior of the support rod.

[0018] In one embodiment, the support platform includes:

[0019] The base is fitted onto the support rod;

[0020] A support frame is fixedly installed on the base, and the blade assembly is rotatably installed on the support frame. In use, the blades on one side of the blade assembly are located below the outlet of the second diversion pipe.

[0021] A splash guard, mounted on the support frame, is used to cover the blades on the other side of the blade assembly.

[0022] In one embodiment, a housing is also mounted on the base, the outlet of the second diverter extends downward through the housing, the generator is located outside the housing, and the rotor of the generator passes through the housing and is connected to the blade assembly.

[0023] A kinetic energy conversion device based on pipeline hydraulics includes a conversion structure and a sealing sleeve. The conversion structure is installed inside the sealing sleeve, and the wall surface of the sealing sleeve is provided with multiple adsorption devices for adsorption onto the inner wall of the pipeline.

[0024] In one embodiment, the adsorption device includes:

[0025] The positioning platform is fixedly installed inside the sealing sleeve and has multiple positioning grooves on its surface.

[0030] The suction cup is rotatably mounted on the connecting rod at one end, and a magnet and a rubber ring are installed at the other end.

[0031] The aforementioned kinetic energy conversion structure and equipment based on pipeline hydraulics involves liquid entering the interior of a support rod through a flow-gathering component and being guided to multiple piezoelectric plates via a first diverter.

This conversion structure, through the installation of piezoelectric plates, blade assemblies, and a series of flow-guiding structures, achieves the conversion of kinetic energy to electrical energy based on the pressure of the flowing liquid. It is suitable for providing power to valves inside liquid pipelines. Attached Figure Description

[0048] The following is combined with Figures 1-8 This invention describes a kinetic energy conversion structure and device based on pipeline hydraulics.

[0049] like Figures 1 to 3As shown, in one embodiment, a kinetic energy conversion structure based on pipeline hydraulics includes a support rod 100, multiple piezoelectric elements 400, a first diversion pipe 310, a water collector 500, a support platform 600, and a second diversion pipe 320. The support rod 100 has two through-holes, with a flow-concentrating component 200 installed at its top. Multiple piezoelectric elements 400 are circumferentially spaced on the outer wall of the support rod 100. The inlet of the first diversion pipe 310 is attached to the inner wall of the support rod 100, and its outlet is located above the multiple piezoelectric elements 400, guiding the liquid to each of the piezoelectric elements 400. The water collector 500 is sleeved on the support rod 100 and located below the multiple piezoelectric elements 400. The support platform 600 is fixed... The second diverter pipe 320 has its inlet attached to the inner wall of the support rod 100 and its outlet located above the multiple blade assemblies 710, which are used to guide the liquid to the multiple blade assemblies 710 respectively. The support rod 100 also has multiple guide holes 110 for discharging the liquid from the collector 500 and the support platform 600.

[0050] Specifically, the first diversion pipe 310 and the second diversion pipe 320 are liquid pipes with one inlet and multiple outlets. The inlets of the first diversion pipe 310 and the second diversion pipe 320 are both attached to the inner wall of the support rod 100. The multiple outlets of the first diversion pipe 310 extend outward through the support rod 100 and are distributed in a ring above the multiple piezoelectric plates 400. The multiple outlets of the second diversion pipe 320 extend outward through the support rod 100 and are respectively located above the multiple blade assemblies 710. The blades on the blade assembly 710 can be set in a bowl shape to facilitate the collection of more liquid and thus accelerate rotation under the action of gravity.

[0051] It should be noted that the heights of the first diversion pipe 310 and the second diversion pipe 320 on the support rod 100 are adjustable. In this embodiment, the first diversion pipe 310 is higher than the second diversion pipe 320. That is, the liquid first flows through the first diversion pipe 310 to the piezoelectric element 400, is collected by the water collector 500, and flows back into the support rod 100 through the guide hole 110 in the middle section of the support rod 100. Then, it flows through the second diversion pipe 320 to the blade assembly 710 and is discharged through the guide hole 110 at the bottom of the support rod 100. The piezoelectric element 400 and the generator 720 can be connected to a battery 730 to store electrical energy, or they can be directly connected to an electric valve to provide power.

[0052] In the aforementioned hydraulic kinetic energy conversion structure, liquid enters the support rod 100 through the flow-concentrating component 200 and is guided to multiple piezoelectric elements 400 via the first diverter pipe 310. When liquid drips onto the piezoelectric elements 400, the elements vibrate under pressure, generating electricity. The dripped liquid is collected by the collector 500 and flows back into the support rod 100 along the guide hole 110. It is then guided to multiple blade assemblies 710 via the second diverter pipe 320. When liquid drips onto the blade assemblies 710, the blades rotate unidirectionally, driving the generator 720 to generate electricity. The dripped liquid flows back into the support rod 100 along the guide hole 110 and is discharged from the bottom of the support rod 100. This conversion structure, by installing piezoelectric elements 400, blade assemblies 710, and a series of guiding structures, can convert kinetic energy into electrical energy based on the pressure of the flowing liquid. It is suitable for providing power to valves installed inside liquid pipelines.

[0053] like Figure 2 As shown, in this embodiment, the radius of the water collector 500 is greater than the length of the piezoelectric sheet 400, and the horizontal height of the water collector 500 increases sequentially from the center to the edge.

[0054] Specifically, the water collector 500 is funnel-shaped, and multiple piezoelectric plates 400 are installed circumferentially on the outer wall of the support rod 100 in a ring structure. The outer diameter of the water collector 500 is larger than the outer diameter of the ring structure. That is, the projection of the piezoelectric plate 400 on the ground is within the projection of the water collector 500 on the ground, so that the water collector 500 can receive the liquid shaken off by the vibration of the piezoelectric plate 400. After the liquid drips into the water collector 500, it flows along the surface to the center and enters the interior of the support rod 100 through the guide hole 110.

[0055] In this embodiment, a fixed magnet 410 is provided at the end of the piezoelectric sheet 400 away from the support rod 100, and multiple brackets 510 are provided at intervals along the circumference of the outer ring of the water collector 500. A movable magnet 520 is installed on the bracket 510. The movable magnet 520 corresponds one-to-one with the fixed magnet 410, and the magnetic poles at adjacent locations are the same.

[0056] Specifically, a fixed magnet 410 is installed on the end of the piezoelectric sheet 400 away from the support rod 100, and a bracket 510 with a movable magnet 520 is set at a corresponding position on the outer ring of the water collector 500, and the magnetic poles of the movable magnet 520 and the fixed magnet 410 are the same at their adjacent ends; when the piezoelectric sheet 400 is vibrated by the dripping liquid, the fixed magnet 410 moves closer to the movable magnet 520. Due to the same magnetic poles, a repulsive magnetic force is generated, which reduces the vibration amplitude of the piezoelectric sheet 400 and increases the vibration frequency, thereby increasing the power generation of the piezoelectric sheet 400.

[0057] like Figure 4As shown, in this embodiment, fixed magnets 410 are installed at the top and bottom ends of the piezoelectric sheet 400 away from the support rod 100, as well as on the side near the bracket 510. Two crossbars are provided on the side of the bracket 510 near the piezoelectric sheet 400, forming a semi-enclosed structure with the bracket 510. The piezoelectric sheet 400 is located within this semi-enclosed structure. Movable magnets 520 are installed at the bottom end of the upper crossbar, the top end of the lower crossbar, and on the side of the bracket 510 near the piezoelectric sheet 400. During the vibration of the piezoelectric sheet 400 caused by liquid dripping, the fixed magnets 410 at the top, bottom, and side ends are repelled by the corresponding movable magnets 520, thereby reducing the vibration amplitude of the piezoelectric sheet 400, increasing its vibration frequency, and improving its power generation.

[0058] In this embodiment, the movable magnet 520 is movably mounted on the bracket 510 by a spring, and the fixed magnet 410 is fixedly mounted on the piezoelectric sheet 400.

[0059] Specifically, both the fixed magnet 410 and the movable magnet 520 are small magnetic blocks with magnetic properties. The fixed magnet 410 can be fixedly mounted on the piezoelectric sheet 400 by embedding or adhesive, while the movable magnet 520 is connected to the bracket 510 by a spring. During the vibration of the piezoelectric sheet 400, the fixed magnet 410 remains relatively stationary with the piezoelectric sheet 400 and vibrates together with it. When the fixed magnet 410 approaches, the movable magnet 520 compresses the spring and moves closer to the bracket 510. When the spring is compressed to its limit, it releases potential energy, pushing the movable magnet 520 away from the bracket 510 and bringing it closer to the fixed magnet 410. At this time, the mutual repulsive magnetic force increases, further reducing the vibration amplitude of the piezoelectric sheet 400 and increasing the vibration frequency of the piezoelectric sheet 400, thereby increasing the power generation of the piezoelectric sheet 400.

[0060] like Figure 1 As shown, in this embodiment, the flow-concentrating assembly 200 includes a filter cover 210 and a reservoir 220. One-way valves are respectively provided at both ends of the reservoir 220. The reservoir 220 is installed at the top of the support rod 100, and the top of the reservoir 220 is connected to the filter cover 210, while the bottom extends into the interior of the support rod 100.

[0061] Specifically, the top of the flow-concentrating component 200 is a filter cover 210. The liquid flowing in the pipeline is filtered through the filter cover 210 to remove impurities before entering the reservoir 220 for operation, preventing impurities in the liquid from damaging the equipment and affecting its use. After being filtered through the filter cover 210, the liquid flows into the reservoir 220. Only one of the one-way valves at the top and bottom of the reservoir 220 is open at a time. During the liquid storage process, the top one-way valve is open and the bottom one-way valve is closed, allowing the liquid to enter the reservoir 220. When the liquid volume inside the reservoir 220 exceeds a certain capacity, the bottom one-way valve opens and the top one-way valve closes, allowing the liquid to flow through the bottom of the reservoir 220 into the support rod 100 and then be guided to multiple piezoelectric elements 400 through the first diverter pipe 310. It should be noted that because the conversion structure is located inside the pipeline, and the liquid flow rate within the pipeline is uneven and uncontrollable, if the liquid flow rate is too high at a certain time, it can easily form a liquid column when discharged from the diversion pipe, resulting in excessive pressure that prevents the piezoelectric element 400 from vibrating. Conversely, if the flow rate is too low, the piezoelectric element 400 will also fail to vibrate. By setting up the liquid reservoir 220, the liquid flow rate is controlled, ensuring that the liquid flowing out of the diversion pipe is sufficient for the piezoelectric element 400 to vibrate without forming a continuous liquid column, thus guaranteeing the power generation efficiency of the conversion structure.

[0062] like Figure 3 and Figure 5 As shown, in this embodiment, the support platform 600 includes a base 610, a support frame 620, and a splash guard 630. The base 610 is sleeved on the support rod 100. The support frame 620 is fixedly installed on the base 610, and the blade assembly 710 is rotatably installed on the support frame 620. In use, the blades on one side of the blade assembly 710 are located below the outlet of the second diversion pipe 320. The splash guard 630 is installed on the support frame 620 and is used to cover the blades on the other side of the blade assembly 710.

[0063] Specifically, taking the second diversion pipe 320 with four outlets as an example, the four outlets of the second diversion pipe 320 extend outward through the support rod 100 and are arranged around the support rod 100. The base 610 is provided with four support frames 620, and a blade assembly 710 is rotatably installed on each support frame 620, so that each outlet of the second diversion pipe 320 corresponds to a blade on one side of a blade assembly 710. The blade on the other side is protected by a splash guard 630 to prevent liquid from splashing and affecting the rotation of the blade assembly 710.

[0064] like Figure 6 As shown, in this embodiment, a housing 640 is also installed on the base 610, the outlet of the second diversion pipe 320 extends downward through the housing 640, the generator 720 is located outside the housing 640, and the rotor of the generator 720 passes through the housing 640 and connects to the blade assembly 710.

[0065] Specifically, the outer casing 640 is mounted on the base 610 with the support rod 100 as the center. The outlet of the second diversion pipe 320 and the blade assembly 710 are located inside the outer casing 640. The outer casing 640 isolates the generator 720 from the battery 730, allowing the rotor of the generator 720 to pass through the outer casing 640 and extend inward to connect to the blade assembly 710, preventing liquid from splashing during the rotation of the blade assembly 710. Due to the special nature of the liquid inside the pipe, if it splashes onto the motor and battery 730, it can easily lead to equipment failure.

[0066] like Figure 7 As shown, in one embodiment, a kinetic energy conversion device based on pipeline hydraulics includes a conversion structure and a sealing sleeve 800, wherein the conversion structure is installed inside the sealing sleeve 800, and the wall surface of the sealing sleeve 800 is provided with a plurality of adsorption devices 900 for adsorbing onto the inner wall of the pipeline.

[0067] Specifically, the conversion structure is installed inside the sealing sleeve 800 and is adsorbed onto the inner wall of the pipe through the adsorption device 900, providing power to the valve inside the pipe without affecting the flow of liquid inside the pipe. Multiple adsorption devices 900 can be arranged at intervals along the circumference of the sealing sleeve 800, and the number and spacing can be adapted to the inner diameter of the pipe.

[0068] It should be noted that, since the sealing sleeve 800 is connected to the inside of the pipe by adsorption, when the pipe is abandoned, the sealing sleeve 800 and the conversion structure can be removed and installed inside other pipes for continued use.

[0069] like Figure 8 As shown, in this embodiment, the adsorption device 900 includes a positioning platform 910, a telescopic platform 920, and multiple adsorption platforms 930. The positioning platform 910 is fixedly installed inside the sealing sleeve 800 and has multiple positioning grooves 912 on its surface. The telescopic platform 920 is located outside the sealing sleeve 800 and has multiple telescopic rods 921 near one end of the sealing sleeve 800. The telescopic rods 921 extend inward through the sealing sleeve 800 and are inserted into the positioning grooves 912. The adsorption platform 930 is installed at the other end of the telescopic platform 920 and is used to adsorb onto the inner wall of the pipe.

[0070] In this embodiment, the adsorption stage 930 includes a connecting rod 931 and a suction cup 932. A spring is sleeved on the connecting rod 931 and is inserted and fixed to the other end of the telescopic stage 920. One end of the suction cup 932 is rotatably mounted on the connecting rod 931, and the other end is equipped with a magnet and a rubber ring.

[0071] Specifically, during the installation of this conversion equipment, the entire equipment is placed into the pipeline, and the telescopic rod 921 is extended to ensure that the adsorption platform 930 fits tightly against the inner wall of the pipeline. When the suction cup 932 of the adsorption platform 930 comes into contact with the pipeline, the connecting rod 931 is inserted into the other end of the telescopic platform 920. The spring fitted on the connecting rod 931 deforms to adapt to different pipeline shapes. At this time, friction is generated between the rubber ring on the suction cup 932 and the pipeline, and the magnetic block generates magnetic force with the inner wall of the pipeline made of metal material, increasing the adsorption capacity of the suction cup 932. The positioning platform 910 and the sealing sleeve 800 can be fixedly connected by welding the positioning post 911.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
