Description

Technical Field

[0001] This invention belongs to the technical field of vertical shaft energy dissipation devices, and particularly relates to a vertical shaft energy dissipation device. Background Technology

[0002] Vertical shaft energy dissipation refers to an engineering technique where a stilling basin, formed by a closed vertical shaft, is used at the bottom of the inlet of a drainage tunnel (or pipeline) to dissipate energy. The stilling basin is connected to the inlet tower or shaft and to a pressureless drainage tunnel or pipeline on its side. Water flows down from the top of the tower, falls into the stilling basin, and undergoes collisions, swirling, and the infiltration of a large amount of air to dissipate most of the residual energy before flowing out through the tunnel (pipeline). To ensure safe flow through the tunnel, the water flow is generally designed as a rapid flow with sufficient space to maintain a pressureless flow state. This energy dissipation method can be considered when there is a large difference in water level between the upstream and downstream areas, facilitating the connection between the water flow at the tunnel outlet and the downstream water level.

[0003] Existing vertical shafts mostly use multiple sets of staggered baffles to block the water flow, gradually reducing the flow velocity to achieve energy dissipation. However, when a large flow of water impacts the baffles, the horizontally designed baffles cannot disperse the impact of the water flow, and the water will splash on the baffles, preventing the water from concentrating in the center of the baffles. Over long-term use, the baffles will be damaged by the impact of the water flow. Therefore, a vertical shaft energy dissipation device is proposed. Summary of the Invention

[0004] This invention addresses the problem that partitions in vertical shafts are easily damaged by impact in existing technologies, and proposes the following technical solution:

[0005] A vertical shaft energy dissipation device includes a vertical shaft, an inlet pipe extending through the top of the shaft, an outlet pipe extending through the outer side of the shaft, a vertical plate fixedly installed at the bottom of the shaft's inner cavity, multiple guide plates fixedly installed on one side of the vertical plate, a conical hole and a rectangular groove on the top of the guide plates, multiple sleeves extending through one side of the vertical plate, multiple water leakage grooves on the outer side of the sleeves, two fixing blocks fixedly installed on the outer side of the sleeves, a cylinder slidably disposed within the inner cavity of the sleeves, multiple water leakage holes on the outer side of the cylinder, two movable rods fixedly installed on the outer side of the cylinder, springs movably sleeved on the outer side of the movable rods, and a water storage box fixedly installed at the end of the cylinder, with multiple circular holes on one side of the water storage box.

[0006] Preferably, there are multiple tapered holes, and the diameters of the multiple tapered holes decrease sequentially. One end of the movable rod passes through the fixed block, and the two ends of the spring are respectively fixedly connected to the opposite surfaces of the fixed block and the movable rod.

[0007] Preferably, the top of the guide plate is rotatably connected with multiple first baffles and multiple second baffles, the bottom end of the second baffle is movably sleeved with a torsion spring, and cylinders are fixedly installed on both sides of the second baffle.

[0008] Preferably, multiple rotating cylinders are rotatably connected to one side of the vertical plate, multiple through slots are opened on the outer side of the rotating cylinders, and multiple guide vanes are fixedly installed on the outer side of the rotating cylinders.

[0009] Preferably, two rectangular boxes are fixedly installed on one side of the vertical plate. A guide groove is provided on the top of the rectangular box. Multiple J-shaped grooves are provided on both sides of the guide groove. Multiple inclined plates are fixedly installed on both sides of the guide groove. A square groove is provided on the top of the guide plate.

[0010] Preferably, the guide vane has an S-shaped design, the upper surface of the bottommost end of the guide vane is a slope, and the slope is inclined downwards towards the rectangular groove, and the multiple guide vanes are symmetrically and staggeredly distributed.

[0011] Preferably, the two ends of the torsion spring are fixed to the opposite surfaces of the second baffle and the guide plate, respectively. The bottom end of the first baffle is also provided with a torsion spring. The second baffle is located between two adjacent first baffles. The end of the cylinder is provided with a rubber ball.

[0012] Preferably, the end of the guide vane is J-shaped, and the through groove is located between two adjacent guide vanes, so that the guide vane does not contact the guide plate.

[0013] Preferably, the inclined plate is located below the opening of the J-shaped groove, and the J-shaped grooves on both sides of the guide groove are symmetrically designed.

[0014] The beneficial effects of this invention are as follows: the water flow can be directed in an S-shape by multiple sets of guide plates, which not only reduces the damage caused by the water flow to the guide plates, but also gradually mitigates the impact force of the water flow. When there is too much water, the cylinder automatically slides along the inner cavity of the sleeve. The air in the dry area can be injected into the water flow through the sleeve and the cylinder, which further reduces the impact force of the water flow.

[0015] When water flows on the surface of the guide plate, the first and second baffles can initially buffer the water flow. When the water flow is too large, the first and second baffles will rotate and contact each other, thereby enabling the first and second baffles to support each other and maintain stability.

[0016] The guide vane can collect the water overflowing from the guide plate. The impact force of the water flow can drive the guide vane to rotate. At this time, the guide vane can discharge the overflowing water through the channel, thereby further reducing the impact force of the water and transporting the overflowing water to the guide plate below.

[0017] When water is delivered from the inlet pipe to the guide plate, some of the water will flow into the guide channel. The J-shaped channel can reverse the flow of water upwards, causing the two water streams to collide when they meet. This greatly dissipates the energy of the water flow, allowing it to slowly drain out of the rectangular box. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Example 1: Combining Figures 1 to 8As shown, the present invention provides a vertical shaft energy dissipation device, including a vertical shaft 1, an inlet pipe 2 penetrating the top of the vertical shaft 1, an outlet pipe 3 penetrating the outer side of the vertical shaft 1, a vertical plate 4 fixedly installed at the bottom of the inner cavity of the vertical shaft 1, multiple guide plates 5 fixedly installed on one side of the vertical plate 4, a conical hole 6 opened at the top of the guide plate 5, a rectangular groove 7 opened at the top of the guide plate 5, the guide plate 5 is S-shaped, the upper surface of the bottommost end of the guide plate 5 is inclined, and the inclined surface slopes downward towards the rectangular groove 7. The guide plates 5 are symmetrically and staggeredly distributed. Multiple sleeves 8 are threaded through one side of the vertical plate 4. Multiple drainage grooves 9 are opened on the outer side of the sleeves 8. Two fixing blocks 10 are fixedly installed on the outer side of the sleeves 8. A cylinder 11 is slidably arranged inside the cavity of the sleeves 8. Multiple drainage holes 12 are opened on the outer side of the cylinder 11. Two movable rods 13 are fixedly installed on the outer side of the cylinder 11. A spring 14 is movably sleeved on the outer side of the movable rods 13. There are multiple conical holes 6, and the diameters of the multiple conical holes 6 decrease sequentially. One end of rod 13 passes through fixed block 10. The two ends of spring 14 are fixedly connected to the opposite surfaces of fixed block 10 and movable rod 13, respectively. A water storage box 15 is fixedly installed at the end of cylinder 11. Multiple round holes 16 are opened on one side of water storage box 15. Multiple first baffles 17 and multiple second baffles 18 are rotatably connected to the top of guide plate 5. A torsion spring 19 is movably sleeved at the bottom of second baffle 18. Cylinders 20 are fixedly installed on both sides of second baffle 18. Multiple rotating cylinders 21 are rotatably connected to one side of vertical plate 4. Multiple through slots 22 are provided on the outer side of the rotating drum 21. Multiple guide vanes 23 are fixedly installed on the outer side of the rotating drum 21. Two rectangular boxes 24 are fixedly installed on one side of the vertical plate 4. A guide groove 25 is provided on the top of the rectangular box 24. Multiple J-shaped slots 26 are provided on both sides of the guide groove 25. Multiple inclined plates 27 are fixedly installed on both sides of the guide groove 25. A square slot 28 is provided on the top of the guide plate 5. The inclined plates 27 are located below the opening of the J-shaped slots 26. The J-shaped slots 26 on both sides of the guide groove 25 are symmetrically designed.

[0030] Specifically, both ends of the vertical plate 4 are in contact with the vertical shaft 1. The vertical plate 4 divides the inner cavity of the vertical shaft 1 into two equal areas: the area where the guide plate 5 is located is the wet area, and the other area is the dry area. The water inlet pipe 2 is located directly above the wet area, and the water outlet pipe 3 is also located on one side of the wet area. Water flows from the water inlet pipe 2 into the guide plate 5. The guide plate 5 has an S-shaped design, so the impact force brought by the water flow is evenly distributed on the surface of the guide plate 5. The bottom end of the guide plate 5 can store the water flow. The upper surface of the bottommost end of the guide plate 5 is a slope, and this slope is inclined downward towards the rectangular groove 7. At this time, the water on the guide plate 5 will be discharged downward from the conical holes 6 and the rectangular groove 7. There are three conical holes 6, and the diameters of the three conical holes 6 decrease sequentially. The conical hole 6 allows water to diffuse from the bottom of the guide plate 5. The diameter of the bottom of the conical hole 6 is larger than the diameter of its top, thus spreading the water in a funnel shape and reducing the impact force of the water flow. The cylinder 11 is located directly below the rectangular groove 7. Some of the water falling from the rectangular groove 7 and the conical hole 6 enters the sleeve 8. The end of the sleeve 8 is connected to the dry area, and the sleeve 8 is designed to be inclined. When the water flows into the sleeve 8, the water will not flow from the sleeve 8 into the dry area, but will enter the cylinder 11 and finally be discharged from the drain hole 12 on the surface of the cylinder 11. When the water reaches the wet area, the air pressure inside the wet area decreases, thereby drawing air from the dry area into the wet area. At this time, the air can mix with the water through the sleeve 8. The water flow is enriched with oxygen. Air can be injected into the water flow through the drain hole 12 of the sleeve 8, thereby further reducing the impact force of the water flow. When water enters the sleeve 8, some water flows into the water storage box 15. When the water flow is too large, the round hole 16 on one side of the water storage box 15 cannot empty the water in the water storage box 15. At this time, the weight of the water storage box 15 increases, thereby driving the cylinder 11 to slide along the inner cavity of the sleeve 8, so that one end of the cylinder 11 is located on the outside of the sleeve 8, thereby increasing the amount of oxygen entering. At this time, the movable rod 13 will also slide along the fixed block 10. The end of the movable rod 13 is provided with a round plate to prevent the cylinder 11 from falling out of the sleeve 8. The water storage box 15 can automatically increase the distance between the sleeve 8 and the cylinder 11 according to the size of the water flow. At this distance, both the water trough 9 and the water hole 12 can mix the air and water in the dry area. The size of the water trough 9 is larger than that of the water hole 12. The water trough 9 can further increase the oxygen content of the water flow, thereby enabling automatic adjustment of the air content according to the water flow size. When the weight of the water storage box 15 is reduced, the spring 14 pulls the movable rod 13 and moves the cylinder 11 into the sleeve 8. Multiple guide plates 5 are symmetrically and staggered. Through the staggered design, the kinetic energy of the water flow is quickly consumed by the initial guide plate 5. Subsequently, when the water flows into the next guide plate 5, its energy is gradually consumed. Through the multi-stage energy dissipation of the guide plates 5 at different positions, the water flow finally reaches a smooth state before being discharged through the outlet pipe 3.

[0031] Example 2: Combination Figure 2 and Figure 6 As shown, based on Embodiment 1, the top of the guide plate 5 is rotatably connected with multiple first baffles 17 and multiple second baffles 18. The bottom end of the second baffle 18 is movably sleeved with a torsion spring 19. Both sides of the second baffle 18 are fixedly installed with cylinders 20. The two ends of the torsion springs 19 are respectively fixed to the opposite surfaces of the second baffle 18 and the guide plate 5. The bottom end of the first baffle 17 is also provided with a torsion spring 19. The second baffle 18 is located between two adjacent first baffles 17. The end of the cylinder 20 is provided with a rubber ball.

[0032] Specifically, when water flows on the surface of the guide plate 5, it is blocked by the first baffle 17 and the second baffle 18. Multiple through holes are provided at the opposite ends of the first baffle 17 and the second baffle 18. These multiple first baffles 17 and multiple second baffles 18 are arranged in a parallel and staggered pattern. The water first flows from the through holes of the first baffle 17 to the second baffle 18, and then flows from the through holes of the second baffle 18 to the next first baffle 17, thus circulating in a cycle to initially buffer the water flow on the guide plate 5 and allow its energy consumption to be initially consumed. When the water flow is large, the through holes of the first baffle 17 cannot quickly discharge the water. A torsion spring 19 is provided at the bottom of the first baffle 17, and the two ends of the torsion spring 19 are respectively fixed to the opposite surfaces of the first baffle 17 and the guide plate 5. At this time, the torsion spring 19 cannot withstand the impact force of the water flow. Then, the first baffle 17 at the top begins to tilt. A round rod is fixedly installed at the bottom of the first baffle 17. The round rod is rotatably connected to the top of the guide plate 5. The round rod is not located at the center of the bottom of the first baffle 17, and the round rod is far away from the second baffle 18. Therefore, the end of the first baffle 17 facing the second baffle 18 will tilt downward. At this time, one side of the first baffle 17 will contact the cylinder 20. At this time, the torsion spring 19 at the bottom of the second baffle 18 also cannot withstand the impact force of the water flow. Under the impact of the water flow, the first baffle 17 presses against the cylinder 20, causing the second baffle 18 to tilt downwards towards one end of the first baffle 17. A rubber ball is provided at the end of the cylinder 20 to reduce friction between the cylinder 20 and the first baffle 17. Once the second baffle 18 begins to tilt, the cylinder 20 on the other side of the second baffle 18 begins to press against the first baffle 17 below it, causing it to tilt as well. This cycle repeats, with multiple first baffles 17 and multiple second baffles 18 arranged in pairs, ultimately forming multiple sets of inverted V-shaped structures. A rectangular block is fixedly installed on the top of the guide plate 5, and this rectangular block is located at the bottom of the first baffle. At the bottom of 17, when the bottommost first baffle 17 begins to tilt, the rectangular block provides support for the first baffle 17, enabling it to stably form an inverted V-shaped structure. Through the mutual support between the first baffle 17 and the second baffle 18, the water flow passes through the gap between the first baffle 17 and the second baffle 18, reducing the damage caused by the water flow to the first baffle 17 and the second baffle 18. At the same time, the water flow is also dispersed by the first baffle 17 and the second baffle 18, so that when the water flow flows at the top of the guide plate 5, it can be guided and buffered to the bottom of the guide plate 5, thereby further dissipating energy by the guide plate 5.

[0033] Example 3: Combination Figure 2 and Figure 7 As shown, based on Embodiment 1, a plurality of rotating cylinders 21 are rotatably connected to one side of the vertical plate 4, a plurality of through slots 22 are opened on the outer side of the rotating cylinders 21, and a plurality of guide vanes 23 are fixedly installed on the outer side of the rotating cylinders 21.

[0034] Specifically, when the water flows into the bottom of the guide plate 5, the semi-circular bottom of the guide plate 5 can disperse the impact force of the water flow, preventing the impact force from acting on the bottom of the guide plate 5 and causing damage. After the water flows to the bottom of the guide plate 5, some of the water will overflow from the bottom of the guide plate 5 due to the impact force. At this time, the overflowing water will come into contact with the guide vane 23. The guide vane 23 will drive the rotating drum 21 to start rotating due to the impact force of the water. The rotating drum 21 and the vertical plate 4 Due to the high friction at the connection point, the rotating drum 21 can only rotate slowly. During the rotation of the guide vane 23, the water carried on the guide vane 23 flows through the through groove 22 into the inner cavity of the rotating drum 21. Then, the water in the inner cavity of the rotating drum 21 is discharged through the through groove 22 again. The water flow discharged after passing through the rotating drum 21 no longer has a large impact force. Then, the water flow in the rotating drum 21 flows into the guide plate 5 below the rotating drum 21 and undergoes the second stage of energy dissipation through the second guide plate 5.

[0035] Example 4: Combination Figure 2 and Figure 8 As shown, based on Embodiment 1, two rectangular boxes 24 are fixedly installed on one side of the vertical plate 4. A guide groove 25 is provided on the top of the rectangular box 24. Multiple J-shaped grooves 26 are provided on both sides of the guide groove 25. Multiple inclined plates 27 are fixedly installed on both sides of the guide groove 25. A square groove 28 is provided on the top of the guide plate 5. The inclined plates 27 are located below the opening of the J-shaped grooves 26. The J-shaped grooves 26 on both sides of the guide groove 25 are symmetrically designed.

[0036] Specifically, the rectangular box 24 is located between two vertical square grooves 28. When water flows through the inlet pipe 2 onto the top guide plate 5, some water flows into the rectangular box 24 through the square grooves 28. The water then flows out through the guide channel 25. As the water flows through the guide channel 25, some water is blocked by the inclined plate 27, which is located below the opening of the J-shaped groove 26. The blocked water then flows into the J-shaped groove 26. The J-shaped grooves 26 on both sides of the guide channel 25 are symmetrically designed. Every two J-shaped grooves 26 on the same horizontal plane form a group. The troughs 26 can be arranged in a heart shape. When water flows through the J-shaped troughs 26, the bottom of the J-shaped troughs 26 can make the downward-flowing water flow upward. Through a set of J-shaped troughs 26, the falling water can be subjected to an upward impact force, and its falling energy can be gradually consumed. At the same time, the faster the water flow speed, the faster the water flow speed at the bottom of the J-shaped troughs 26. Through multiple sets of J-shaped troughs 26, the impact force of the water flow can be continuously consumed, so that it flows smoothly into the bottom of the vertical shaft 1. Through two sets of rectangular boxes 24, the kinetic energy of the water flow can be greatly consumed, so that it is finally discharged smoothly from the outlet pipe 3.

[0037] Example 5: Combination Figure 2 and Figure 7As shown, in the above embodiment, the end of the guide vane 23 is designed in a J shape, and the through groove 22 is located between two adjacent guide vanes 23, and the guide vane 23 does not contact the guide plate 5.

[0038] Specifically, the guide vane 23 does not contact the guide plate 5, and the end of the guide vane 23 is J-shaped. When the water overflowing from the guide plate 5 comes into contact with the guide vane 23, the guide vane 23 can collect the water at its end to prevent the water from being thrown out from the end of the guide vane 23. The through groove 22 is located between two adjacent guide vanes 23. When the guide vane 23 rotates to the highest point, the water at the end of the guide vane 23 will flow into the through groove 22 and then be discharged from the inner cavity of the rotating cylinder 21 to the guide plate 5 located below.

[0039] The working principle and usage process of this invention are as follows: When water flows into the interior of the vertical shaft 1 from the inlet pipe 2, the water flow reaches the surface of the guide plate 5. The water flow is then blocked by the first baffle 17 and the second baffle 18. The water first flows from the through hole of the first baffle 17 to the second baffle 18, and then flows through the through hole of the second baffle 18 to the next first baffle 17, thus circulating to initially buffer the water flow on the guide plate 5. When the water flow is large, the end of the first baffle 17 tilts downwards. At this time, one side of the first baffle 17 contacts the cylinder 20. Subsequently, the second baffle 18 is also tilted under pressure. The cylinder 20 on the other side of the second baffle 18 then presses against the first baffle 17 below it, causing it to tilt as well. This cycle continues. This allows multiple first baffles 17 and multiple second baffles 18 to stably form multiple inverted V-shaped structures, thus initially dissipating energy from the water flow. When the water flows to the bottom of the guide plate 5, it will be discharged downwards from the conical hole 6 and the rectangular groove 7. Some of the water falling from the rectangular groove 7 and the conical hole 6 will enter the sleeve 8. At this time, the air and water in the dry area can be mixed through the sleeve 8, making the water rich in oxygen, thereby further reducing the impact force brought by the water flow. When the water flow is too large, the weight of the water storage box 15 will gradually increase, thereby driving the cylinder 11 to slide to the outside of the sleeve 8. The water storage box 15 can automatically increase the distance between the sleeve 8 and the cylinder 11 according to the size of the water flow. Subsequently, the water leakage groove 9 and the water leakage hole 12 will drain the water. In the dry zone, air and water flow mix, consuming the kinetic energy of the water. When the weight of the water storage box 15 decreases, the spring 14 pulls the movable rod 13, causing the cylinder 11 to move into the sleeve 8. When the water flows into the bottom of the guide plate 5, some of the water overflows from the bottom of the guide plate 5 due to the impact force. The guide vane 23 drives the rotating cylinder 21 to start rotating due to the impact force of the water. The guide vane 23 can collect water at its end to prevent water from being thrown out from the end of the guide vane 23. When the guide vane 23 rotates to the highest point, the water at the end of the guide vane 23 flows into the through groove 22, and then is discharged from the inner cavity of the rotating cylinder 21 onto the guide plate 5 located below. The guide plate 5 located below will repeat the above operation, that is, the water is blocked by the first baffle 17 and the second baffle 22. The water is blocked by baffle 18, and then air is injected by sleeve 8 and cylinder 11. Then, guide vane 23 dissipates the energy of the water overflowing from guide plate 5. This cycle continues, and the rapid water flow is gradually slowed down through a step-by-step energy dissipation method. When the water flows into the guide plate 5 at the top through inlet pipe 2, some of the water will flow into rectangular box 24 through square groove 28. When the water flows in guide groove 25, some of the water will be blocked by inclined plate 27, allowing the water to flow in J-shaped groove 26. The bottom of J-shaped groove 26 can make the downward flowing water flow upward. Through a set of J-shaped grooves 26, the falling water flow can be subjected to an upward impact force, so that the energy of the falling water is gradually consumed. Moreover, the faster the water flow speed, the faster the water flow speed at the bottom of J-shaped groove 26.Multiple sets of J-shaped channels 26 continuously dissipate the impact force of the water flow, allowing it to flow smoothly to the bottom of the vertical shaft 1. Finally, the energy-dissipated water is discharged from the outlet pipe 3.
