Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to a siphon-type modification device for ecological flow release in reservoirs. Background Technology

[0002] Traditional ecological flow release methods mainly involve burying pipelines downstream of the dam or setting up floodgates. However, the construction or renovation of release facilities involves large-scale engineering projects, significantly impacts the dam structure, and incurs high renovation costs, making it difficult to promote and apply on a large scale. Furthermore, these methods rely on power equipment such as water pumps, resulting in high energy consumption and maintenance costs during long-term operation, which significantly increases the burden on reservoir operations. In addition, they cannot achieve precise and stable release of ecological flow, making it difficult to adapt to dynamically changing ecological needs. They are also not adaptable to operating conditions such as reservoir water level fluctuations and water quality changes, and are susceptible to environmental interference that can lead to release failure.

[0003] While existing reservoir siphon devices can achieve unpowered discharge and reduce energy consumption by utilizing the siphon principle, in practical applications, the siphon process relies on negative pressure to form a continuous water flow. Once floating objects such as leaves, branches, aquatic plants, and garbage, as well as large particles, enter the pipe, they will not only impact the pipe wall and cause wear, but also easily accumulate in the pipe, block the pipe opening, jam the pipe, or even form air pockets, directly causing siphon failure and resulting in the interruption of ecological flow. At the same time, siphon pipes are mostly buried underwater or at the bottom of the reservoir, and cannot be cleaned at any time like open channels. They need to rely on pre-filters to prevent the risk of pipe blockage, but existing filters have limited self-cleaning effects and cannot meet the needs of continuous and stable ecological flow discharge from reservoirs.

[0004] Therefore, there is an urgent need to provide a siphon-type modification device for ecological flow release in reservoirs to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a siphon-type modification device for ecological flow release in reservoirs.

[0006] The technical solution adopted to solve the above technical problems is: a siphon-type modification device for ecological flow release in reservoirs, including a reservoir body, a diversion tank fixed at the top of the reservoir body, and an inlet pipe fixed on one side of the top of the diversion tank;

[0007] A water pump is fixed inside the drainage tank, with one end penetrating through and extending to the outside. A water outlet pipe is fixed to the outlet of the water pump, and an air valve is fixed to the other side of the top of the drainage tank.

[0008] The reservoir body is equipped with a control mechanism on its exterior to achieve precise and stable release of ecological flow, and one end of the inlet pipe is equipped with a self-cleaning mechanism to filter the siphon of the inlet pipe.

[0009] The self-cleaning mechanism has a rotating mechanism on one side of its top for achieving all-around automated cleaning, and a lifting mechanism on the other side of its top to reduce the frequency of manual cleaning.

[0010] With the above technical solution, after the water pump starts, the diversion tank is in a negative pressure state. The diversion tank draws water from the reservoir through the inlet pipe. The water enters the diversion tank through the inlet pipe and is then discharged from the outlet pipe by the water pump. The water in the upstream reservoir automatically flows into the siphon pipe under atmospheric pressure, forming a continuous water flow and realizing the basic release of ecological flow. When it is necessary to stop the release or deal with special working conditions, air is injected into the diversion tank through the air valve to destroy the siphon condition and the water flow is automatically interrupted, ensuring the controllability of the release process.

[0011] Furthermore, the control mechanism includes a color steel shell fixed to the outside of the outlet pipe, a flow regulating valve fixed to one end of the outlet pipe, an electromagnetic flow meter fixed to one end of the flow regulating valve, a pipe support fixed to one side of the reservoir body that is tightly fitted to the outlet pipe, and a trash rack fixed to one side of the reservoir body.

[0012] By adjusting the opening of the flow regulating valve, the pipe resistance of the outlet pipe can be changed, thereby accurately controlling the ecological flow release. The electromagnetic flowmeter monitors the flow data in real time and feeds the data back to the control system, which facilitates the dynamic adjustment of the release parameters according to ecological needs, ensuring the accuracy and stability of the flow release. The pipe support provides stable support for the outlet pipe and prevents pipe displacement. The trash rack can intercept large-volume impurities in the reservoir water, preventing impurities from entering the release system and protecting the internal components of the device.

[0013] Furthermore, the self-cleaning mechanism includes a filter frame fixed to one end of the water inlet pipe, a fixing sleeve fixed to the top of the filter frame, and a connecting frame fixed between the water inlet pipe and the fixing sleeve.

[0014] Through the above technical solution, the filter frame adopts a frame structure composed of two mounting circular plates. Multiple dividing rings are stacked between the two mounting circular plates and fixed by six vertical rods. This can effectively filter large particulate impurities in the water, prevent impurities from entering the inlet pipe and causing blockage, ensure the smooth siphon process, and enhance the connection stability between the fixed sleeve and the inlet pipe through the connecting frame.

[0015] Furthermore, a scraper rotating frame is rotatably mounted inside the filter frame, an annular circular plate is fixed to the inner top wall of the filter frame, and two first gears are rotatably mounted between the filter frame and the annular circular plate.

[0016] Through the above technical solution, the scraper rotating frame consists of an upper toothed disc and a lower rotating disc forming a frame structure. Six rotating scrapers are fixed to the outside of the upper toothed disc and the lower rotating disc. Each rotating scraper has a double-toothed scraper stacked on one side. The upper toothed disc is sealed between the annular plate and the mounting plate through a sealing ring to prevent the upper toothed disc from being affected by impurities. The upper toothed disc is meshed with two first gears to ensure that the upper toothed disc can rotate smoothly through the first gears. During operation, the rotating scrapers scrape the inner wall of the separating ring, and the double-toothed scrapers scrape the side walls of adjacent separating rings, achieving a comprehensive cleaning of the inside of the filter frame and preventing the accumulation of impurities.

[0017] Furthermore, a scraper lifting frame is slidably mounted on the outside of the filter frame, and a lifting sleeve is fixed at the top of the scraper lifting frame. The inside of the lifting sleeve is slidably connected to the outside of the fixed sleeve.

[0018] Through the above technical solution, the scraper lifting frame is composed of a frame structure consisting of lifting ring plates. The lifting ring plates can be raised and lowered smoothly through the water inlet pipe. Six arc-shaped scrapers are fixed at the bottom of the lifting ring plates, which can scrape the outer wall of the dividing ring. The lifting sleeve is raised and lowered smoothly through the fixed sleeve, thereby driving the scraper lifting frame to be raised and lowered smoothly, thus achieving cleaning of the outside of the filter frame.

[0019] Furthermore, the rotating mechanism includes a first fixed shell fixed to the top of the fixed sleeve, a first worm gear shaft rotatably mounted inside the first fixed shell, an internal hexagonal rotating rod that penetrates and extends into the filter frame at one end of the first worm gear shaft, and a second gear fixed at one end of the internal hexagonal rotating rod.

[0020] Through the above technical solution, the second gear meshes with the upper gear plate, the first worm gear shaft drives the internal hexagonal rod to rotate, the internal hexagonal rod drives the second gear to rotate, and the second gear drives the scraper rotating frame to rotate through the upper gear plate, thereby automatically cleaning the filter frame.

[0021] Furthermore, the lifting mechanism includes a telescopic sleeve fixed to the top of the lifting sleeve, an installation sleeve is slidably installed on the outside of the telescopic sleeve, and a second fixing shell is fixed to the top of the installation sleeve.

[0022] Through the above technical solution, the telescopic sleeve extends and retracts by installing a sleeve, and the telescopic sleeve drives the lifting sleeve to rise and fall accordingly, thereby driving the scraper lifting frame to achieve the lifting action.

[0023] Furthermore, a second worm gear shaft is rotatably mounted inside the second fixed shell. One end of the second worm gear shaft is fitted with an internal hexagonal screw that penetrates and extends into the telescopic sleeve. The external part of the internal hexagonal screw is threadedly connected to the internal part of the telescopic sleeve.

[0024] Through the above technical solution, the second worm gear shaft drives the internal hexagonal screw to rotate, and the internal hexagonal screw drives the telescopic sleeve to extend and retract through a threaded connection with the telescopic sleeve.

[0025] Furthermore, a motor is fixed to one end of both the first and second fixed housings, and the output shafts of the two motors are fixedly connected to a worm gear via a coupling. The outer surfaces of the two worm gears mesh with the outer surfaces of the first and second worm wheel shafts, respectively.

[0026] With the above technical solution, the two mounting motors drive the two mounting worms to rotate, and the two mounting worms drive the first worm wheel shaft and the second worm wheel shaft to rotate respectively.

[0027] The beneficial effects of this invention are as follows:

[0028] (1) The present invention has a self-cleaning mechanism, and the filter frame filters the water inlet siphon port at the source, effectively intercepting debris, reducing the risk of pipe blockage and equipment damage from the root, ensuring the long-term stable operation of the fluid transport system, while reducing the frequency and cost of later maintenance. The scraper rotating frame and scraper lifting frame realize the automated cleaning of the inside and outside of the filter frame, respectively, which greatly saves labor costs, significantly improves the system operating efficiency and automation level, and ensures the continuous and stable operation of the system.

[0029] (2) The present invention is provided with a rotating mechanism and a lifting mechanism. The rotating mechanism is connected to the scraper rotating frame and drives the scraper rotating frame to rotate through the second gear, so that the scraper rotating frame scrapes and cleans the inside of the filter frame, thereby realizing the automated cleaning of the inside of the filter frame. The lifting mechanism is connected to the scraper lifting frame and drives the scraper lifting frame to move up and down through the telescopic sleeve, so that the scraper lifting frame scrapes and cleans the outside of the filter frame. The two work together to realize the all-round automated cleaning of the inside and outside of the filter frame, reducing the number of times manual cleaning is required, and avoiding system downtime caused by manual cleaning, thereby significantly improving the operating efficiency and automation of the device.

[0030] (3) This invention utilizes the siphon principle, eliminating the need for power equipment such as water pumps, thus significantly reducing operating energy consumption and costs. The regulating valve and flow meter work together to achieve precise and stable release of ecological flow, meeting the refined needs of the downstream ecosystem, effectively restoring and improving the ecological environment of the downstream river channel, protecting aquatic biodiversity. Furthermore, the device is mainly arranged on the top of the dam or the upper part of the dam body, having little impact on the dam structure. The amount of renovation work is small, and the investment cost is low, significantly lower than that of traditional solutions. It is easy to promote and apply in various water conservancy projects, and has good economic efficiency and practicality. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 and not intended to limit the invention.

[0041] like Figures 1-8As shown, this embodiment of a siphon-type modification device for ecological flow release in a reservoir includes a reservoir body 1. A diversion tank 2 is fixed to the top of the reservoir body 1, and an inlet pipe 3 is fixed to one side of the top of the diversion tank 2. A water pump 4 is fixed inside the diversion tank 2, with one end penetrating and extending to the outside. An outlet pipe 5 is fixed to the outlet of the water pump 4. An air valve 6 is fixed to the other side of the top of the diversion tank 2. A control mechanism 7 for precise and stable ecological flow release is provided outside the reservoir body 1. The control mechanism 7 includes a color steel shell 701 fixed to the outside of the outlet pipe 5. A flow regulating valve 702 is fixed to one end of the outlet pipe 5, and an electromagnetic flow meter 703 is fixed to one end of the flow regulating valve 702. A pipe support 704, tightly fitted to the outlet pipe 5, is fixed to one side of the reservoir body 1. A trash rack 705 is fixed to one side of the reservoir body 1. After the water pump 4 is started, the diversion tank 2 is placed under negative pressure. The diversion tank 2 releases water through the inlet pipe 3 into the reservoir body 1. Water is drawn from the source of body 1, and enters the diversion tank 2 through the inlet pipe 3. Then, it is discharged from the outlet pipe 5 through the water pump 4. Under atmospheric pressure, the water from the upstream reservoir automatically flows into the siphon pipe, forming a continuous water flow and realizing the basic release of ecological flow. When it is necessary to stop the release or deal with special working conditions, air is injected into the diversion tank 2 through the air valve 6 to destroy the siphon condition and automatically interrupt the water flow, ensuring the controllability of the release process. Adjusting the opening of the flow regulating valve 702 can change the pipe resistance of the outlet pipe 5, thereby accurately controlling the ecological flow release. The electromagnetic flowmeter 703 monitors the flow data in real time and feeds the data back to the control system, which facilitates the dynamic adjustment of the release parameters according to ecological needs, ensuring the accuracy and stability of the flow release. The pipe support 704 provides stable support for the outlet pipe 5 to prevent pipe displacement. The trash rack 705 can intercept large-volume impurities in the reservoir water, preventing impurities from entering the release system and protecting the internal components of the device.

[0042] like Figures 2-8As shown, one end of the water inlet pipe 3 is equipped with a self-cleaning mechanism 8 for filtering the siphon port of the water inlet pipe 3; the self-cleaning mechanism 8 includes a filter frame 801 fixed to one end of the water inlet pipe 3, a fixing sleeve 802 fixed to the top of the filter frame 801, a connecting frame 803 fixed between the water inlet pipe 3 and the fixing sleeve 802, a scraper rotating frame 804 rotatably mounted inside the filter frame 801, an annular circular plate 805 fixed to the inner top wall of the filter frame 801, and two first gears 806 rotatably mounted between the filter frame 801 and the annular circular plate 805. A scraper lifting frame 807 is slidably mounted on the outside of the filter frame 801. A lifting sleeve 808 is fixed to the top of the scraper lifting frame 807. The inside of the lifting sleeve 808 is slidably connected to the outside of the fixed sleeve 802. The filter frame 801 adopts a frame structure composed of two mounting circular plates. Multiple dividing rings are stacked between the two mounting circular plates and fixed by six vertical rods. This effectively filters large particles of impurities in the water, prevents impurities from entering the inlet pipe 3 and causing blockage, and ensures the smooth siphon process. (Connecting frame) 803 enhances the stability of the connection between the fixed sleeve 802 and the water inlet pipe 3. The scraper rotating frame 804 consists of an upper gear plate and a lower rotating plate forming a frame structure. Six rotating scrapers are fixed to the outside of the upper gear plate and the lower rotating plate. Each rotating scraper has a stacked double-tooth scraper fixed on one side. The annular circular plate 805 and the mounting circular plate are sealed with the upper gear plate through a sealing ring to prevent the upper gear plate from being affected by impurities. The upper gear plate is meshed with two first gears 806 to ensure that the upper gear plate can rotate smoothly through the first gears 806. During operation, the rotating scrapers... The inner wall of the dividing ring is scraped, and the double-toothed scraper scrapes the side wall of the adjacent dividing ring, achieving a thorough cleaning of the inside of the filter frame 801 and preventing the accumulation of impurities. The scraper lifting frame 807 is a frame structure composed of lifting ring plates. The lifting ring plates can be raised and lowered smoothly through the water inlet pipe 3. Six arc-shaped scrapers are fixed at the bottom of the lifting ring plates, which can scrape the outer wall of the dividing ring. The lifting sleeve 808 is raised and lowered smoothly through the fixed sleeve 802, which in turn drives the scraper lifting frame 807 to be raised and lowered smoothly, achieving cleaning of the outside of the filter frame 801.

[0043] like Figures 3-5As shown, a rotating mechanism 9 for omnidirectional automated cleaning is provided on one side of the top of the self-cleaning mechanism 8. The rotating mechanism 9 includes a first fixed shell 901 fixed to the top of the fixed sleeve 802. A first worm gear shaft 903 is rotatably installed inside the first fixed shell 901. One end of the first worm gear shaft 903 is fitted with an internal hexagonal rotating rod 904 that penetrates and extends into the filter frame 801. A second gear 905 is fixed to one end of the internal hexagonal rotating rod 904. The second gear 905 meshes with the upper gear plate. The first worm gear shaft 903 drives the internal hexagonal rotating rod 904 to rotate. The internal hexagonal rotating rod 904 drives the second gear 905 to rotate accordingly. The second gear 905 drives the scraper rotating frame 804 to rotate accordingly through the upper gear plate, thereby automatically cleaning the filter frame 801.

[0044] like Figures 2-5 As shown, a lifting mechanism 10 is provided on the other side of the top of the self-cleaning mechanism 8 to reduce the frequency of manual cleaning. The lifting mechanism 10 includes a telescopic sleeve 1001 fixed to the top of the lifting sleeve 808. An installation sleeve 1002 is slidably installed on the outside of the telescopic sleeve 1001. A second fixed shell 1003 is fixed to the top of the installation sleeve 1002. A second worm gear shaft 1004 is rotatably installed inside the second fixed shell 1003. One end of the second worm gear shaft 1004 is fitted with an internal hexagonal screw 1005 that penetrates and extends into the inside of the telescopic sleeve 1001. The outside of the internal hexagonal screw 1005 is threadedly connected to the inside of the telescopic sleeve 1001. A mounting motor 1006 is fixed to one end of both the first fixed shell 901 and the second fixed shell 1003. The output of the two mounting motors 1006 is... Each output shaft is fixedly connected to a mounting worm gear 1007 via a coupling. The outer surfaces of the two mounting worm gears 1007 are respectively meshed with the outer surfaces of the first worm wheel shaft 903 and the second worm wheel shaft 1004. Two mounting motors 1006 drive the two mounting worm gears 1007 to rotate, which in turn drive the first worm wheel shaft 903 and the second worm wheel shaft 1004 to rotate. The second worm wheel shaft 1004 drives the internal hexagon screw 1005 to rotate. The internal hexagon screw 1005 is threadedly connected to the telescopic sleeve 1001, causing the telescopic sleeve 1001 to extend and retract. The telescopic sleeve 1001 extends and retracts via the mounting sleeve 1002, which in turn causes the lifting sleeve 808 to rise and fall, thus driving the scraper lifting frame 807 to achieve the lifting action.

[0045] The working principle of this embodiment is as follows: After the water pump 4 is started, the diversion tank 2 is in a negative pressure state. The diversion tank 2 draws water from the reservoir body 1 through the inlet pipe 3. After the water is filtered by the trash rack 705 and the filter frame 801, it enters the diversion tank 2 from the inlet pipe 3 and is then discharged from the outlet pipe 5 through the water pump 4. The upstream reservoir water automatically flows into the siphon pipe under atmospheric pressure, forming a continuous water flow and realizing the basic release of ecological flow.

[0046] Adjusting the opening of the flow regulating valve 702 can change the pipe resistance of the outlet pipe 5, thereby precisely controlling the ecological flow discharge. The electromagnetic flow meter 703 monitors the flow data in real time and feeds the data back to the control system, which facilitates dynamic adjustment of discharge parameters according to ecological needs, ensuring the accuracy and stability of flow discharge. When it is necessary to stop the discharge or deal with special working conditions, air is injected into the diversion tank 2 through the air valve 6 to destroy the siphon condition and automatically interrupt the water flow, ensuring the controllability of the discharge process.

[0047] When the filter frame 801 needs to be cleaned, the two mounting motors 1006 are started. The two mounting motors 1006 drive the two mounting worm gears 1007 to rotate, and the two mounting worm gears 1007 drive the first worm wheel shaft 903 and the second worm wheel shaft 1004 to rotate.

[0048] The second worm gear shaft 1004 drives the internal hexagon screw 1005 to rotate. The internal hexagon screw 1005 is connected to the telescopic sleeve 1001 by a thread, which drives the telescopic sleeve 1001 to extend and retract. The telescopic sleeve 1001 extends and retracts through the mounting sleeve 1002. The telescopic sleeve 1001 drives the lifting sleeve 808 to rise and fall accordingly, driving the scraper lifting frame 807 to achieve the lifting action, thereby cleaning the outer wall of the filter frame 801.

[0049] The first worm gear shaft 903 drives the internal hexagonal rotating rod 904 to rotate, and the internal hexagonal rotating rod 904 drives the second gear 905 to rotate accordingly. The second gear 905 drives the scraper rotating frame 804 to rotate through the upper gear plate, thereby automatically cleaning the inside of the filter frame 801.
