Description

Technical Field

[0001] This invention belongs to the technical field of hydropower generation, specifically relating to a water resource energy recovery device. Background Technology

[0002] In large energy facilities such as thermal power plants and nuclear power plants, the circulating water system is a core auxiliary unit, mainly driven by multiple parallel circulating water pumps. After cooling, the circulating water usually flows into the return water well and is directly discharged into natural water bodies. These water bodies still carry significant residual pressure energy when discharged, resulting in a waste of hydraulic energy.

[0003] To avoid wasting hydropower energy, the current mainstream approach is to introduce water into hydroelectric power generation equipment, thereby converting hydropower energy into electrical energy. However, the low residual head of the circulating water, meaning insufficient water flow velocity, means that the impact force of the circulating water cannot overcome the starting resistance of the power generation equipment.

[0004] Currently, most systems utilize the natural height difference between the elevated water tank and the downstream turbine to generate the effective head required to drive the turbine. However, the flow rate of the circulating water system is not absolutely stable; it fluctuates with changes in the operating load of power plants and nuclear power plants. Furthermore, the volume of the elevated water tank is limited. When the inflow rate suddenly increases or the outflow rate suddenly decreases, the water level in the elevated water tank fluctuates. These fluctuations directly affect the stability of the output head of the elevated water tank, thereby affecting the stability of the power generation equipment's operation. Summary of the Invention

[0005] This invention provides a water resource energy recovery device, which aims to solve the technical problem of poor operational stability of power generation equipment caused by sudden changes in circulating water flow.

[0008] In one possible implementation, the pressure-applying structure includes: The first movable seat is rotatably connected to the support frame; An annular moving component is connected to the first moving seat and is used to drive the first moving seat to rotate about the central axis of the inlet bucket.

[0009] In one possible implementation, the reservoir bag includes: The upper plate is fixedly connected to the support frame, and a water inlet is provided through the surface of the upper plate; A water receiving hopper is located inside the water inlet. The water receiving hopper is slidably connected to the upper plate in the vertical direction. A valve is installed inside the water receiving hopper. The lower plate is fixedly connected to the support frame, and a water outlet is provided through the plate surface of the lower plate; A sealing plate is disposed inside the water outlet, and the sealing plate is rotatably connected to the lower plate. The rotation axis of the sealing plate is perpendicular to the vertical direction. The first elastic element is installed at the connection between the sealing plate and the lower plate, and has a pre-tightening force that keeps the sealing plate blocking the water outlet; A flexible bag, fixedly connected between the upper plate and the lower plate, the flexible bag having two openings, one of which is connected to the water inlet and the other opening is connected to the water outlet; and A triggering component is disposed between the water receiving hopper and the squeezing plate. When the squeezing plate squeezes the flexible bag, the triggering component draws the water receiving hopper into the water inlet and closes the valve.

[0010] In one possible implementation, a trigger cavity is provided inside the upper board; The triggering component includes: The trigger block is slidably connected to the bottom surface of the lower plate along the radial direction of the upper plate; The linkage rod is slidably connected to the inner wall of the trigger cavity in the up-down direction, and the bottom end of the linkage rod extends out of the upper plate; Two positioning rollers are sequentially arranged in the trigger cavity along the vertical direction; A trigger rope, one end of which is fixed to the top of the linkage rod, and the other end passing between the two positioning rollers and fixed to the water receiving hopper; and The second elastic element is fixed between the water receiving hopper and the upper plate, and has a pre-tightening force that causes the water receiving hopper to be drawn into the water inlet.

[0016] The water resource energy recovery device provided by this invention, compared with the prior art, utilizes an inlet unit to dynamically and flexibly distribute circulating water into multiple storage bladders, replacing the high-level water tank that is susceptible to flow fluctuations and avoiding interference from water level fluctuations on the stability of the output head. The energy-enhancing unit then sequentially compresses each storage bladder through energy-enhancing components, pressurizing and storing the originally low-flow-rate, low-impact circulating water within the bladders, transforming it into a high-pressure water flow with sufficient driving force. Finally, the outlet unit guides the pressurized water into a power generation device for energy recovery and power generation. This invention, through its "dynamic allocation, independent pressurization, and continuous output" working mode, not only significantly improves the energy recovery efficiency of low-quality water resources but also ensures that the power generation device can operate continuously and reliably under stable head conditions, unaffected by upstream circulating water flow fluctuations, thus improving the operational stability of the power generation device.

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] Please refer to the following: Figures 1 to 3 The water resource energy recovery device of the present invention will be described below. A water resource energy recovery device includes a support frame 10, which, from top to bottom, is provided with an inlet unit 20, an energizing unit 30, and an outlet unit 40. The inlet unit 20 includes an inlet bucket 201 fixed to the support frame 10, a guide pipe 202 connected to the inlet bucket 201, and a power component 203 connected to the guide pipe 202. The power component 203 is used to drive the guide pipe 202 to move around the central axis of the inlet bucket 201. The power component 203 is a ring-shaped slide rail, and is fixedly connected to the support frame 10. The slide of the power component 203 is fixedly connected to the inlet bucket 201. The energizing unit 30 includes multiple liquid storage bags connected to the guide pipe 202 and an energizing component. The multiple liquid storage bags are spaced apart along the movement trajectory of the guide pipe 202, and the energizing component is used to sequentially squeeze each liquid storage bag. The outlet unit 40 is connected to the liquid storage bags and is used to guide the water squeezed out of the liquid storage bags into a power generation device.

[0021] It should be noted that an on / off valve is provided at the bottom of the guide tube 202, which is used to control the opening and closing of the guide tube 202.

[0022] The water resource energy recovery device provided in this embodiment first allows circulating water to enter the inlet hopper 201. The power component 203 drives the guide pipe 202 to move around the central axis of the inlet hopper 201, guiding the water flow sequentially to the storage bags located at different positions below its movement trajectory for filling. When a storage bag is filled to a certain extent, the energy-enabling component is activated to squeeze the storage bag. The squeezing action increases the pressure of the water inside the storage bag, converting the energy of the low-head water flow into high-pressure water with higher driving capacity. The pressurized high-pressure water is released from the storage bag and enters the docked outlet unit 40. The outlet unit 40 stably delivers this high-pressure water flow to the downstream power generation equipment to drive it to generate electricity, completing the conversion of water energy into electrical energy.

[0023] The guide tube 202 moves continuously, filling other liquid storage bags with water; the energy-generating components sequentially squeeze the water-filled liquid storage bags; the discharge unit 40 receives and delivers the squeezed-out high-pressure water. The three units work together to form a continuous dynamic energy recovery cycle.

[0024] Compared with existing technologies, the inlet unit 20 dynamically and flexibly distributes circulating water into multiple storage bladders, replacing the high-level water tank that is susceptible to flow fluctuations and avoiding interference from water level fluctuations on the stability of the output head. The energizing unit 30 then sequentially compresses each storage bladder through energizing components, pressurizing and storing the originally low-flow-rate, low-impact circulating water within the bladders, transforming it into a high-pressure water flow with sufficient driving force. Finally, the outlet unit 40 guides the pressurized water into the power generation equipment for energy recovery and power generation. This invention, through its "dynamic allocation, independent pressurization, and continuous output" working mode, not only significantly improves the energy recovery efficiency of low-quality water resources but also ensures that the power generation equipment can operate continuously and reliably under stable head conditions, unaffected by upstream circulating water flow fluctuations, thus improving the stability of the power generation equipment operation.

[0025] In some embodiments, see Figure 1 The enabling components include a squeezing structure and a pressure applying structure that correspond one-to-one with the liquid storage bladder. The pressure applying structure is used to drive the squeezing structure to squeeze the corresponding liquid storage bladder.

[0026] The extrusion structure includes a fixed plate 301 and an extrusion sheet 302; the fixed plate 301 extends in the vertical direction, and a through groove 3011 is opened through the plate surface of the fixed plate 301; one side of the extrusion sheet 302 is fixedly connected to the fixed plate 301, and the other side passes through the through groove 3011. The extrusion sheet 302 and the fixed plate 301 enclose an extrusion area for placing the liquid storage bag, and the extrusion sheet 302 is made of flexible material.

[0027] The pressure-applying structure begins to work, pulling the extrusion plate 302 through the through groove 3011, causing the extrusion plate 302 to gradually reduce the extrusion area. With the lateral constraint of the fixing plate 301, the liquid storage bag undergoes compression deformation, and the water inside the liquid storage bag is efficiently pressurized. The extrusion plate 302 maintains the pressure until the water inside the liquid storage bag reaches the predetermined pressure and is discharged. After the pressure is released, the extrusion plate 302 returns to its original position along the path of the through groove 3011, preparing for the next extrusion cycle.

[0028] The fixed plate 301 extends vertically and has a through groove 3011. Its core function is to provide a precise guiding path for the movement of the extrusion plate 302, ensuring that the extrusion plate 302 acts on the liquid storage bag during the pressurization process. This avoids pressure loss caused by deviation in the extrusion direction, thereby maximizing the conversion of mechanical extrusion force into effective pressure energy of the water. At the same time, the extrusion area formed by the fixed plate 301 and the extrusion plate 302 physically constrains the lateral expansion deformation of the flexible liquid storage bag under high pressure, preventing the liquid storage bag from rupturing or suffering fatigue damage due to excessive or irregular deformation. This greatly extends the service life of key consumables and ensures the feasibility of the device to continuously and stably perform high-intensity energy recovery operations under fluctuating circulating water flow conditions.

[0029] In some embodiments, see Figure 1 The pressure-applying structure includes a first movable seat 303, an annular movable member 304, a second movable seat 305, a linear movable member 306, and an adsorption member 307. The first movable seat 303 is rotatably connected to the support frame 10. The annular movable member 304 is drively connected to the first movable seat 303 and is used to drive the first movable seat 303 to rotate about the central axis of the guide bucket 201. The annular movable member 304 is an annular slide rail and is fixedly connected to the support frame 10. The slide of the annular movable member 304 is connected to the first movable seat 305. The movable seat 303 is fixedly connected; the second movable seat 305 is slidably connected to the first movable seat 303; the linear moving member 306 is drivenly connected to the second movable seat 305 and is used to drive the second movable seat 305 to move radially along the movement trajectory of the guide tube 202. The linear moving member 306 is a linear slide rail. The linear moving member 306 is fixedly connected to the support frame 10, and the slide of the linear moving member 306 is fixedly connected to the second movable seat 305; the adsorption member 307 is fixedly connected to the second movable seat 305 and is used to adsorb and fix with the extrusion plate 302.

[0030] Specifically, the first movable seat 303, the second movable seat 305, the linear moving member 306, and the adsorption member 307 each correspond to a liquid storage bag, and the annular moving member 304 has a slide that corresponds to the first movable seat 303.

[0031] Optionally, the adsorption element 307 is an electric vacuum suction cup. When the adsorption element 307 is powered on, it generates a suction force on the extrusion plate 302. When the adsorption element 307 is powered off, the suction force disappears.

[0032] Optionally, the adsorption component 307 is an electromagnetic component. In this case, the extrusion sheet 302 is provided with ferromagnetic material. When the adsorption component 307 is energized, it generates an attractive force to adsorb the ferromagnetic material. When the adsorption component 307 is de-energized, the attractive force disappears.

[0033] The annular moving part 304 is activated, driving the first moving seat 303 to move so that the adsorption member 307 aligns with the compression piece 302 corresponding to the target liquid storage bag; the linear moving part 306 drives the second moving seat 305 to move so that the adsorption member 307 approaches and firmly adsorbs the target compression piece 302. The linear moving part 306 continues to drive the second moving seat 305 to move in the opposite direction. At the same time, the annular moving part 304 is activated, causing the corresponding first moving seat 303 to move. Thus, the compression piece 302 compresses the liquid storage bag located in the corresponding compression area.

[0034] The adsorption fixation method enables rapid and reliable engagement and separation of the pressure application mechanism and the extrusion plate 302, significantly improving the automation and reliability of continuous operation of the device. At the same time, the synergistic effect of the first moving seat 303 and the second moving seat 305 ensures that the movement trajectory of the extrusion plate 302 is arc-shaped, thereby avoiding jamming of the extrusion plate 302 during the contraction process and improving the smoothness of the movement of the extrusion plate 302. This provides a key guarantee for efficient and stable energy recovery under low head and variable flow conditions.

[0035] In some embodiments, see Figures 1 to 3 The liquid storage bag includes an upper plate 308, a water receiving hopper 309, a lower plate 310, a sealing plate 311, a first elastic element, a flexible bag 312, and a trigger assembly. The upper plate 308 is fixedly connected to the support frame 10, and a water inlet 3081 is provided through the surface of the upper plate 308. The water receiving hopper 309 is located inside the water inlet 3081 and is slidably connected to the upper plate 308 in the vertical direction. A valve, which is an electronic valve, is installed inside the water receiving hopper 309. The lower plate 310 is fixedly connected to the support frame 10, and a water outlet 3101 is provided through the surface of the lower plate 310. The sealing plate 311 is located inside the water outlet 3101 and is connected to the lower plate 310. The sealing plate 311 is dynamically connected, with its rotation axis perpendicular to the vertical direction. A first elastic element is installed at the connection between the sealing plate 311 and the lower plate 310, providing a pre-tightening force to keep the sealing plate 311 blocking the outlet 3101. The first elastic element is a torsion spring. A flexible bag 312 is fixed between the upper plate 308 and the lower plate 310. The flexible bag 312 has two openings, one of which is connected to the inlet 3081, and the other is connected to the outlet 3101. A triggering component is located between the water receiving hopper 309 and the squeezing plate 302. When the squeezing plate 302 squeezes the flexible bag 312, the triggering component pulls the water receiving hopper 309 into the inlet 3081 and closes the valve.

[0036] Specifically, a trigger cavity 3082 is provided inside the upper plate 308; the trigger assembly includes a trigger block 313, a linkage rod 314, two positioning rollers 315, a trigger rope 316, and a second elastic member 319; the trigger block 313 is slidably connected to the bottom surface of the lower plate 310 along the radial direction of the upper plate 308; the linkage rod 314 is slidably connected to the inner wall of the trigger cavity 3082 along the vertical direction, and the bottom end of the linkage rod 314 extends out of the upper plate 308; the two positioning rollers 315 are arranged sequentially in the trigger cavity 3082 along the vertical direction; one end of the trigger rope 316 is fixedly connected to the top end of the linkage rod 314, and the other end passes between the two positioning rollers 315 and is fixedly connected to the water receiving hopper 309; the second elastic member 319 is fixedly connected between the water receiving hopper 309 and the upper plate 308, and has a pre-tightening force that causes the water receiving hopper 309 to be drawn into the water inlet 3081, and the second elastic member 319 is a spring or a spring rod.

[0037] After the flexible bag 312 is filled with water, the squeezing plate 302 first squeezes the trigger block 313 without contacting the flexible bag 312. After the trigger block 313 is squeezed, it squeezes the linkage rod 314, causing the linkage rod 314 to move upward. During the upward movement of the linkage rod 314, the trigger rope 316 releases the water receiving bucket 309. Under the action of the second elastic element 319, the water receiving bucket 309 is drawn into the water inlet 3081, thereby avoiding the movement of the guide tube 202. After the guide tube 202 is removed, the corresponding valve and the on / off valve are closed. The squeezing plate 302 continues to contract, thus starting to squeeze the flexible bag 312.

[0038] When the flexible bag 312 is squeezed, the water inside the flexible bag 312 continues to increase in pressure until the water pressure overcomes the elastic force of the first elastic element and opens the outlet 3101. At this time, the flexible bag 312 continues to be squeezed, so that the outlet 3101 remains open until the water pressure inside the flexible bag 312 can no longer overcome the elastic force of the first elastic element.

[0039] Before the guide tube 202 moves to the top of the next liquid storage bag to inject water, the squeezing plate 302 squeezes the trigger block 313, causing the linkage rod 314 to move upward, thereby drawing the water receiving hopper 309 into the water inlet 3081. After the central axis of the guide tube 202 is aligned with the central axis of the water receiving hopper 309, the squeezing plate 302 moves away from the trigger block 313. Under the action of the second elastic member 319, the water receiving hopper 309 extends and connects with the guide tube 202. At the same time, the corresponding valves and the on / off valves are opened, allowing circulating water to flow into the flexible bag 312 through the water receiving hopper 309. The flexible bag 312 gradually fills up. At this time, the sealing plate 311 remains in the state of blocking the water outlet 3101 under the pre-tightening force of the first elastic member.

[0040] The above process is repeated, causing the water in the flexible bag 312 to be pressurized and discharged in sequence, thereby continuously introducing water with a stable head into the power generation equipment, ensuring the operational stability of the equipment.

[0041] In some embodiments, see Figure 2 The positioning roller 315 is rotatably connected to the upper plate 308, and the positioning roller 315 rotates around its own central axis.

[0042] Specifically, the upper plate 308 has a clearance groove 3083 that communicates with the water inlet 3081. The clearance groove 3083 is used to avoid the trigger rope 316.

[0043] Another variation of the positioning roller 315 configuration is that the positioning roller 315 is fixedly connected to the upper plate 308.

[0044] It should be noted that the maximum stroke of the linkage rod 314 is when the connection point between the linkage rod 314 and the trigger rope 316 is aligned with the gap between the two positioning rollers 315. Correspondingly, the maximum stroke of the water receiving hopper 309 is when the connection point between the water receiving hopper 309 and the trigger rope 316 is aligned with the gap between the two positioning rollers 315. Furthermore, the gravity of the linkage rod 314 can overcome the sum of the elastic force of the second elastic element 319 and the water pressure during water intake.

[0045] When the extrusion plate 302 presses the trigger block 313, forcing the linkage rod 314 to move upward, the end of the trigger rope 316 fixed to the linkage rod 314 moves upward, thereby gradually shortening the distance between the two ends of the trigger rope 316, causing the second elastic member 319 to gradually release its elasticity, thereby drawing the water receiving bucket 309 into the water inlet 3081; when the trigger block 313 moves away from the linkage rod 314, the linkage rod 314 moves downward due to its own weight, causing the end of the trigger rope 316 fixed to the linkage rod 314 to move downward, thereby increasing the distance between the two ends of the trigger rope 316, thereby gradually compressing the second elastic member 319, causing the water receiving bucket 309 to move upward and extend out of the water inlet bucket.

[0046] If the positioning roller 315 is fixed to the upper plate 308, the friction between the trigger rope 316 and the positioning roller 315 will be aggravated, thereby shortening the service life of the trigger rope 316. However, by rotating the positioning roller 315, the friction between the trigger rope 316 and the positioning roller 315 will be reduced, thereby increasing the service life of the trigger rope 316.

[0047] In some embodiments, the triggering component further includes a force sensor for monitoring the elastic force of the second elastic element 319, and the force sensor is communicatively connected to the valve.

[0048] The force sensor measures the elastic force of the second elastic element 319 to determine whether the water receiving hopper 309 is in the state of receiving water into the inlet 3081 or extending water out of the inlet 3081, thereby determining the timing of valve opening and closing.

[0049] In some embodiments, see Figure 1 The enabling component also includes a limiting structure corresponding to the extrusion sheet 302; the limiting structure includes two support columns 317 and two limiting rollers 318; the two support columns 317 are disposed opposite to each other on both sides of the extrusion sheet 302, the support columns 317 extend in the vertical direction, and the bottom end support frame 10 of the support column 317 is fixedly connected; the limiting rollers 318 are disposed corresponding to the top of the support column 317.

[0050] Optionally, the limiting roller 318 is rotatably connected to the support column 317, and the limiting roller 318 rotates around its own central axis.

[0051] Optionally, the limiting roller 318 is fixedly connected to the support column 317.

[0052] When the extrusion plate 302 extrudes the flexible bag 312, the support column 317 is fixed to the support frame 10 in the vertical direction to form a rigid foundation, while the limiting roller 318 located at the top of the support column 317 provides physical constraints from both sides of the movement trajectory of the extrusion plate 302, limiting the movement trajectory of the extrusion plate 302. This symmetrical layout of double support columns 317 and double limiting rollers 318 not only effectively resists the torsional load that may be generated by the mechanical transmission chain when the circulating water flow changes suddenly, but also prevents the extrusion plate 302 from circumferentially shifting or overturning under high pressure.

[0053] If the limiting roller 318 is fixed to the support column 317, the friction between the extrusion sheet 302 and the limiting roller 318 will be aggravated, thereby shortening the service life of the extrusion sheet 302. However, by using the limiting roller 318 to rotate, the friction between the extrusion sheet 302 and the limiting roller 318 will be reduced, thereby increasing the service life of the extrusion sheet 302.

[0054] In some embodiments, see Figure 1 The outflow unit 40 includes an outflow bucket 401, an outflow pipe 402, and a drive component 403. The outflow pipe 402 is connected to the outflow bucket 401 and fixedly connected to the support frame 10. The drain outlet of the outflow pipe 402 is located above the opening of the power generation equipment. The drive component 403 is connected to the outflow bucket 401 and is used to drive the outflow bucket 401 to move along the movement trajectory of the guide pipe 202. The drive component 403 is a ring slide rail, and the slide of the drive component 403 is fixedly connected to the outflow bucket 401.

[0055] When the flexible bag 312 is pressurized for drainage, the drive unit 403 is activated, aligning the outlet bucket 401 with the corresponding flexible bag 312 to receive the high-pressure water. The outlet bucket 401 then transports the high-pressure water to the power generation equipment through the outlet pipe 402. Through the coordinated action of the movable outlet bucket 401 and the fixed outlet pipe 402, the outlet of the high-pressure water is always at the same location, regardless of which flexible bag 312 is draining water.

[0056] In some embodiments, the diameter of the outlet bucket 401 gradually decreases from top to bottom.

[0057] After the water enters the cone-shaped outlet bucket 401, it accelerates downstream as the cross-section contracts, further enhancing the impact force of the water.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
