Description

Technical Field

[0001] This invention belongs to the field of water conservancy equipment technology, specifically, it relates to a water conservancy energy dissipation device. Background Technology

[0002] With the development of my country's water conservancy and hydropower industry, many remote areas have escaped the life of water and electricity shortages, and many reservoirs and water transmission networks built in mountainous areas have played an important role in this. Implementing local pressure control on water transmission networks is an important way to reduce the leakage rate of the network. Due to the large elevation differences in mountainous water transmission networks and the existence of sections with large drops in gravity flow, pressure reduction and energy dissipation treatment is necessary to reduce the threat of high-energy water flow to the low-lying water transmission network.

[0003] When an open valve is suddenly closed, the water flow exerts pressure on the valve and pipe walls. Due to the smoothness of the pipe walls, the subsequent water flow, under the influence of inertia, quickly reaches its maximum and causes damage; this is known as the "water hammer effect" in hydraulics. The water hammer effect is a phenomenon that poses a significant threat to water pipelines and equipment and cannot be ignored.

[0004] In existing technologies, water hammer effects are mainly addressed by pressure reducing valves or stilling wells, which employ a single-stage energy dissipation method. However, their energy dissipation capacity is relatively low. Furthermore, the impact of sandy water sources in mountainous areas on pressure reducing valves is greater, and the wear rate is more pronounced. Sediment in sandy water sources accumulates in stilling wells, reducing their energy dissipation capacity. Existing equipment is not suitable for sandy water sources in mountainous areas.

[0021] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application. Similarly, the following examples are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0026] In this invention, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the invention.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0027] In this invention, the concept of "generally presents" describes the main features of an overall structure or shape. When describing the shape of an object, this means that the object primarily presents a certain shape, but may differ in non-functional details. These differences in detail do not affect the overall features and can therefore be categorized as "generally presents" a certain shape. For example, when describing a rectangular object, stating "generally rectangular" means that the overall shape of the object is circular, but there are differences in some non-functional details. Similarly, when describing a cube, stating "generally cubic" means that the overall shape of the object is cubic, but there are differences in some non-functional details.

[0028] In some implementations, please refer to Figures 1 to 8 A hydraulic energy dissipation device is provided, comprising: First energy dissipation component 1; First energy dissipation component 1 has a first energy dissipation passage 11; First energy dissipation passage 11 is used to connect with raw water pipeline, and energy dissipation filter screen 12 is provided in the first energy dissipation passage 11; Second energy dissipation component 2; Second energy dissipation component 2 has a second energy dissipation passage 21; Second energy dissipation passage 21 is connected to first energy dissipation passage 11 through first connecting pipe 4; Energy dissipation water wheel 22 is rotatably installed inside second energy dissipation passage 21; Second connecting pipe 5 is connected to the outlet of second energy dissipation passage 21; The third energy dissipation component 3 has a receiving cavity 32 that is connected to the second connecting pipe 5; the receiving cavity 32 is provided with an energy dissipation structure 31; the receiving cavity 32 is connected to a water outlet pipe 6; the water in the second connecting pipe 5 flows out from the water outlet pipe 6 after passing through the energy dissipation structure 31.

[0029] Through the energy dissipation filter 12 of the first energy dissipation component 1, the energy dissipation water wheel 22 of the second energy dissipation component 2, and the energy dissipation structure 31 of the third energy dissipation component 3, energy is dissipated in stages, which can effectively reduce the threat of high-energy water flow to the low-lying water transmission network. At the same time, the energy dissipation filter 12 not only dissipates the water flow, but also filters the silt in the water, reducing the impact of silt on the second energy dissipation component 2 and the third energy dissipation component 3. This device can adapt to mountainous water sources containing silt.

[0030] In some embodiments, the first energy dissipation component 1 has a flushing passage 13; a drain outlet 14 is provided on the side of the first energy dissipation passage 11; the flushing passage 13 is connected to the drain outlet 14 through the energy dissipation filter 12; a first solenoid valve 71 is provided at both ends of the first energy dissipation passage 11, a second solenoid valve 72 is connected to the drain outlet 14, and a third solenoid valve 73 is provided on the flushing passage 13.

[0031] The flushing passage 13 allows water to pass through the energy dissipation filter 12, flushing out the sediment adhering to the filter 12 and discharging it from the drain outlet 14. This flushing of the energy dissipation filter 12 facilitates better filtration of sediment.

[0032] Specifically, the flushing passage 13 is located within the first energy dissipation passage 11. The direction in which the water in the flushing passage 13 passes through the energy dissipation filter 12 is opposite to the direction in which the water in the first energy dissipation passage 11 passes through the energy dissipation filter 12.

[0033] In some embodiments, the first solenoid valve 71, the second solenoid valve 72, and the third solenoid valve 73 are all electrically connected to the processor 7. The processor 7 controls the opening and closing of the first solenoid valve, the second solenoid valve 72, and the third solenoid valve 73 to connect the first energy dissipation passage 11 or the flushing passage 13.

[0034] Specifically, pressure sensors 74 are installed on both sides near the filter screen to measure water pressure. When the pressure difference between the two pressure sensors 74 reaches a predetermined range, the flushing passage 13 is activated (i.e., the first solenoid valve 71 is closed, and the second solenoid valve 72 and the third solenoid valve 73 are opened) to flush the energy-dissipating filter screen 12. Flushing stops when the pressure difference detected by the two pressure sensors 74 decreases to a new preset value. The first energy-dissipating passage 11 is then activated (i.e., the first solenoid valve 71 is opened, and the second solenoid valve 72 and the third solenoid valve 73 are closed).

[0035] In some embodiments, the first energy dissipation component 1 includes: a first pipe body 15, a second pipe body 16, a third pipe body 17, and an L-shaped partition 18; two first solenoid valves 71 are respectively located at both ends of the first pipe body 15, and a drain outlet 14 is located on the side of the first pipe body 15; the second pipe body 16 is connected to the drain outlet 14, and a second solenoid valve 72 is provided on the second pipe body 16; the third pipe body 17 is located inside the first pipe body 15, and a third solenoid valve 73 is provided on the third pipe body 17, and the outlet of the third pipe body 17 is connected to the outlet of the second pipe body 16 through an energy dissipation filter screen 12; The partition 18 has a first section 181 located inside the first tube 15 and a second section 182 located inside the second tube 16; and the first section 181 and the second section 182 are respectively fixedly connected to the first tube 15 and the second tube 16; the energy dissipation filter 12 is fixedly connected to the inner wall of the second section 182 and the second tube 16.

[0036] Specifically, there are multiple partitions 18, which are arranged in a cross shape; the first segment 181 extends along the axial direction of the first tube 15, and the second segment 182 extends along the axial direction of the second tube 16; and the edges of the partitions 18 are fixedly connected to the inner walls of the first tube 15 and the second tube 16.

[0037] The L-shaped baffle 18 allows water to flow in the first energy dissipation passage 11 and impact the baffle 18, reducing the impact of the water flow on the energy dissipation filter 12. At the same time, the baffle 18 also performs a certain energy dissipation function in the first energy dissipation passage 11.

[0038] The first tube 15 has two solenoid valves at both ends, and the two first solenoid valves 71 are distributed on both sides of the partition 18.

[0039] Specifically, there are two drain outlets 14, each of which is connected to a second pipe body 16; there are two energy dissipation filters 12, which are symmetrically distributed on both sides of the third pipe body 17.

[0040] Specifically, the partition 18 divides the first energy dissipation passage 11 into two passages, each of which is equipped with a first solenoid valve 71. This allows the energy dissipation filter 12 in one passage to be in normal filtration mode while the energy dissipation filter 12 in the other passage is in flushing mode. This enables flushing and filtration to be carried out simultaneously, thus ensuring that the first energy dissipation passage 11 can continuously flow with water and preventing the water flow from stopping in the first energy dissipation passage 11 due to the need to flush the energy dissipation filter 12.

[0041] In some embodiments, the second energy dissipation component 2 includes: an energy dissipation pipe 23, a rotating shaft 24, and a compression spring 25; an energy dissipation water wheel 22 is rotatably disposed within the energy dissipation pipe 23 via the rotating shaft 24; the rotating shaft 24 is rotatably connected to the energy dissipation pipe 23; the compression spring 25 is located within the energy dissipation pipe 23, and the rotating shaft 24 abuts against the compression spring 25. When the water flow in the second energy dissipation passage 21 impacts the energy dissipation water wheel 22, the energy dissipation water wheel 22 transmits the impact force of the water to the rotating shaft 24, and the rotating shaft 24 compresses the compression spring 25, causing the compression spring 25 to compress and convert the impact energy into elastic potential energy. The elastic potential energy is then released after the water flow stabilizes. This reduces the impact of the water flow on the energy dissipation water wheel, and at the same time, the water flow drives the energy dissipation water wheel 22 to rotate, converting the kinetic energy of the water flow into rotational energy, thereby achieving energy dissipation of the water flow.

[0042] Specifically, there are two helical springs 25, both of which are set inside a sleeve 27; the rotating shaft 24 passes through the two compression springs 25, and a limiting protrusion is fixed on the rotating shaft 24. The limiting protrusion is limited between the two compression springs 25 and can rotate relative to the compression springs 25.

[0043] Specifically, the energy dissipation impeller 22 is truncated cone-shaped and equipped with rotating blades for energy dissipation. The energy dissipation impeller 22 also has through holes. The through holes effectively dissipate energy from the water flow.

[0044] In some embodiments, the second energy dissipation component 2 further includes a generator 26; the generator 26 is fixedly disposed outside the energy dissipation pipe 23, and the generator 26 is connected to the rotating shaft 24 for transmission. The generator 26 can convert water energy into electrical energy, thus dissipating water energy while fully utilizing water resources.

[0045] In some embodiments, the third energy dissipation component 3 includes an outer shell 33 with a receiving cavity 32, and the energy dissipation structure 31 includes a first barrel 311, a second barrel 312, and a third barrel 313; the first barrel 311 is located inside the second barrel 312, the second barrel 312 is located inside the third barrel 313, and the outer shell 33 is fitted over the third barrel 313. Water flows sequentially through the first barrel 311, the second barrel 312, and the third barrel 313 to dissipate energy, which can greatly reduce the kinetic energy of the water.

[0046] In some embodiments, the first barrel 311, the second barrel 312, and the third barrel 313 are coaxially arranged and radially spaced apart; a grid 34 is fixedly provided at the intervals of the first barrel 311, the second barrel 312, and the third barrel 313. When water flows through the grid 34, the grid 34 increases the resistance to the water flow, thus playing a role in dissipating energy from the water flow.

[0047] Specifically, the grille 34 is a plate located in the middle of the barrel, and the plate has multiple evenly distributed through holes.

[0048] In some embodiments, a first water outlet 314 is provided on the side wall of the first barrel 311, the second barrel 312, and the third barrel 313; The third energy dissipation component 3 also includes a switching structure 35; the switching structure 35 includes: a baffle 351 for blocking the water from the first water outlet 314, a rotating joint 352 fixedly connected to the baffle 351, and a lever 356 fixedly connected to the rotating joint 352; the rotating joint 352 is rotatably connected to the outer shell 33, and the rotating joint 352 is rotatably connected to one end of the first tank 311, the second tank 312, and the third tank 313; a second water outlet 353 is provided on the rotating joint 352; the rotating joint 352 is connected to the second connecting pipe 5; by rotating the rotating joint, the first water outlet can be opened and the second water outlet closed, or the second water outlet can be opened and the first water outlet closed.

[0049] Depending on the different layout scenarios, the first water outlet 314 or the second water outlet 353 can be opened or closed to improve the device's adaptability to the environment.

[0050] Specifically, the rotary joint 352 has two adjustment positions. In the first limit position, the first water outlet 314 is blocked by the baffle 351, and the second water outlet 353 is connected to the first tank 311, the second tank 312, and the third tank 313. In the second limit position, the second water outlet 353 is blocked by the side wall of the first tank 311, the second tank 312, and the third tank 313, and the first water outlet 314 is connected to the first tank 311, the second tank 312, and the third tank 313.

[0051] When the rotating joint 352 is in the first limit position, the third energy dissipation component 3 is suitable for vertical arrangement, that is, the first tank 311, the second tank 312, and the third tank 313 extend in the vertical direction. After the first tank 311 is filled with water, it overflows from the second outlet 353 into the second tank 312. When the second tank 312 is filled with water, it overflows into the third tank 313. After the third tank 313 is filled, it overflows and enters the receiving cavity 32, and finally flows out from the outlet pipe 6. This design can better dissipate energy from the water flow.

[0052] When the rotating joint 352 is in the second limit position, the third energy dissipation component 3 is suitable for horizontal arrangement, that is, the first tank 311, the second tank 312, and the third tank 313 extend in the horizontal direction. After the first tank 311 is filled with water, it overflows from the first outlet 314 into the second tank 312. When the second tank 312 is filled with water, it overflows into the third tank 313. After the third tank 313 is filled, it overflows and enters the receiving cavity 32, and finally flows out from the outlet pipe 6. This design can better dissipate energy from the water flow.

[0053] In the first limit position, the lever 356 rotates to contact the first limit lever 354; in the second limit position, the lever 356 rotates to contact the second limit lever 355.

[0054] All the first water outlets 314 on the same set of tanks are located on the same plane, and when the third energy dissipation component 3 is placed horizontally, the plane containing all the first water outlets 314 is perpendicular to the horizontal plane. This ensures that the water will only overflow when the tank is full.

[0055] The axes of the first water outlets 314 are arranged parallel to each other. When water enters the second tank 312 from the first tank 311, the water flow impacts the wall of the second tank 312, thus enhancing the energy dissipation effect of the water flow. Similarly, when water enters the third tank 313 from the second tank 312, the water flow impacts the wall of the second tank 312, thus enhancing the energy dissipation effect of the water flow.

[0056] Furthermore, since the axes of the first water outlets 314 are arranged parallel to each other, the flow distance of the water within the second barrel 312 and the third barrel 313 is increased, making it easier to flush away the mud and sand within the second barrel 312 and the third barrel 313.

[0057] The inner walls of the ends of the first barrel 311, the second barrel 312, and the third barrel 313 are slidably abutting against the rotating joint 352; the inner walls of the ends of the first barrel 311, the second barrel 312, and the third barrel 313 are provided with slots that can communicate with the second water outlet 353. When the rotating joint 352 is in the first limiting position, the second water outlet 353 communicates with the slot; when the rotating joint 352 is in the second limiting position, the second water outlet 353 is misaligned with the slot, and the inner walls of the ends of the first barrel 311, the second barrel 312, and the third barrel 313 block the second water outlet 353.

[0058] Each second water outlet 353 is spaced apart circumferentially and radially on the rotary joint 352. When water enters the second tank 312 from the first tank 311, the water flow impacts the wall of the second tank 312, thus enhancing the energy dissipation effect. Similarly, when water enters the third tank 313 from the second tank 312, the water flow impacts the wall of the second tank 312, further enhancing the energy dissipation effect.

[0059] Furthermore, since each of the second water outlets 353 is spaced apart in both the circumferential and radial directions of the rotary joint 352, the flow distance of the water within the second barrel 312 and the third barrel 313 is increased, making it easier to flush away the mud and sand within the second barrel 312 and the third barrel 313.

[0060] In some embodiments, the bottom of the first barrel 311, the second barrel 312, and the third barrel 313 are each equipped with a brush 36. A rotating shaft 37 is fixedly connected to each brush 36. The rotating shaft 37 passes through the bottom of the first barrel 311, the second barrel 312, and the third barrel 313 and is rotatably connected to the outer casing 33. A drive motor 38 is driven by the rotating shaft 37 and is fixedly connected to the outer casing 33. The drive motor 38 is also electrically connected to the generator 26. By driving the brush 36 to rotate via the drive motor 38, the mud and sand at the bottom of the barrels are agitated and overflow along with the injected water, eventually flowing out through the outlet pipe 6, thus preventing the accumulation of mud and sand at the bottom of the barrels. This improves the energy dissipation capacity of the barrels. Simultaneously, the kinetic energy of the water flow is converted into electrical energy and then into the kinetic energy of the brush 36, making full use of water energy.
