Description

Technical Field

[0001] This invention relates to the field of river ecological management equipment technology, specifically to a distributed hydraulic barrier device for river ecological management. Background Technology

[0002] Hydraulic dams are a relatively simple movable dam technology in water conservancy. They are widely used in agricultural irrigation, fisheries, ship locks, seawater tide control, urban river landscape projects, and small hydropower stations. Hydraulic lifting dams are movable dams that utilize the mechanical principles of dump trucks combined with the hydraulic structure of pier dams, possessing both water-blocking and water-discharging functions.

[0003] When existing hydraulic dams obstruct water flow in river channels, they also block floating debris on the water surface and sediment at the bottom of the river. To improve the ecological environment of the river, it is necessary to clean up the floating debris and sediment at the bottom of the river regularly. Currently, when cleaning up floating debris on the river surface, workers can easily retrieve debris near the river edge using hand nets while standing at the river edge. However, when the river is wide and it is impossible to retrieve floating debris in the middle of the river from the edges, it is necessary to use boats to transport workers to the middle of the river for retrieval, which is inconvenient. At the same time, it is not easy to clean up the sediment accumulated at the bottom of the river near the hydraulic dam, which is not conducive to the ecological management of the river.

[0004] Therefore, this application proposes a distributed hydraulic barrier device for river ecological management. Summary of the Invention

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] To address the technical problems in the background art, the following embodiments are provided:

[0046] Combination Figures 1-10As shown, the distributed hydraulic barrier device for river ecological management provided by the present invention includes multiple bases 1 arranged in a horizontal linear array, with adjacent bases 1 touching each other on opposite sides. A barrier plate 2 is hinged to the top of each base 1. A hydraulic cylinder 11 is installed on each base 1 to drive the barrier plate 2 to rotate. In use, the multiple bases 1 are arranged in a horizontal linear array and fixed in the river channel, with adjacent bases 1 touching each other on opposite sides. The hydraulic cylinder 11 causes the barrier plate 2 to rotate on the base 1, so that the multiple barrier plates 2 are located on the same inclined surface, thus forming a hydraulic dam. A cavity 21 communicating with the top of the barrier plate 2 is opened inside the barrier plate 2. Multiple through holes 22, all communicating with the cavity 21, are opened in the middle of the side of the barrier plate 2 away from the hydraulic cylinder 11, and a discharge hole 23 is opened at the bottom. The side of the barrier plate 2 closest to the hydraulic cylinder 11... A discharge hole 24 is provided, which is connected to the cavity 21. A sealing mechanism 3 is installed on the baffle plate 2 and located inside the cavity 21. It is used to seal or unseal the cavity 21. Through the design of the through hole 22, when a small amount of water in the river needs to be discharged, the sealing mechanism 3 is unsealed to seal the cavity 21, and the water can flow through the through hole 22 into the cavity 21 and be discharged through the discharge hole 24. This effectively avoids the situation where floating objects flow out of the baffle plate 2 when the baffle plate 2 is rotated on the base 1 by the hydraulic cylinder 11 for flood discharge. A cleaning mechanism 4 is installed on the baffle plate 2 and located inside the discharge hole 23. It is used to clean the silt accumulated at the bottom of the river. A baffle net 25 is fixed at the top position on the side of the baffle plate 2 away from the hydraulic cylinder 11. A cleaning mechanism 5 is installed on multiple baffle plates 2 and below the baffle net 25. It is used to clean floating objects on the water surface.

[0047] In use, multiple barrier plates 2 block the water source in the river channel, and the barrier net 25 blocks floating objects on the water surface, preventing the floating objects from being swept to the outside of the barrier plates 2 by the water waves. When it is necessary to clean the floating objects on the water surface, the cleaning mechanism 5 can be used to clean the floating objects on the water surface. It is not necessary to use boats to carry the staff to the middle of the river channel for retrieval, which is more convenient. By setting up the cleaning mechanism 4, the silt accumulated at the bottom of the river channel can be cleaned, which facilitates the cleaning of silt accumulated at the hydraulic dam at the bottom of the river channel and is conducive to the ecological management of the river channel.

[0048] In this embodiment, the sealing mechanism 3 includes: a sealing plate 31, which is movably inserted into the cavity 21 along the top of the barrier plate 2, the sealing plate 31 is in contact with the inside of the cavity 21, a first threaded rod 32 that is threadedly connected to the sealing plate 31 is rotatably installed on the barrier plate 2 and located in the cavity 21, and an installation cavity 26 is opened in the barrier plate 2 and located below the cavity 21, the bottom of the first threaded rod 32 extends into the installation cavity 26, and a first motor 33 that is connected to the first threaded rod 32 is fixedly installed in the installation cavity 26.

[0049] In use, the first motor 33 is turned on, and the output shaft of the first motor 33 rotates, which drives the first threaded rod 32 to rotate, so that the sealing plate 31 can slide outward or inward within the cavity 21. When the bottom of the sealing plate 31 moves above the through hole 22, the sealing of the through hole 22 can be canceled, which is convenient for control.

[0050] In this embodiment, the cleaning mechanism 4 includes: a cleaning plate 41, which is rotatably mounted in the discharge hole 23 via a rotating shaft 42; a mounting groove 27 is provided on the barrier plate 2; one end of the rotating shaft 42 extends into the mounting groove 27; wherein, in this embodiment, a sealing plate for sealing the opening end of the mounting groove 27 is fixedly mounted on the barrier plate 2 by screws; a second motor 43 is fixedly mounted in the mounting groove 27; and the output shaft of the second motor 43 is connected to the rotating shaft 42 via a first bevel gear assembly 44.

[0051] In use, the first motor 33 is turned on, causing the sealing plate 31 to slide outward within the cavity 21, displacing the bottom of the sealing plate 31 above the discharge hole 23. Then, the second motor 43 is turned on, and the second motor 43 drives the rotating shaft 42 to rotate through the first bevel gear assembly 44, thereby driving the cleaning plate 41 to rotate. This pushes the mud and sand accumulated at the bottom of the river near the discharge hole 23 into the discharge hole 23, and then discharges it through the cavity 21 and the discharge hole 24, achieving the effect of cleaning the mud and sand.

[0052] In this embodiment, the clearing mechanism 5 includes: a movable plate 51, on which a groove 28 is provided on the barrier plate 2 and below the barrier net 25, such that when two adjacent barrier plates 2 are in contact, the two adjacent grooves 28 are connected, and the movable plate 51 is slidably connected to the groove 28; and a traction mechanism 52, on which support frames 12 are fixedly installed on two mutually distant bases 1 and on the outer side of the barrier plate 2, and traction mechanisms 52 are installed on both support frames 12. The traction mechanism 52 includes a fixed frame 521 fixedly installed on the support frame 12, a winding roller 522 rotatably installed on the fixed frame 521, a pull rope 523 wound on the winding roller 522, the end of the pull rope 523 being fixedly connected to the movable plate 51, and a motor 524 for driving the winding roller 522 to rotate fixedly installed on the fixed frame 521.

[0053] In use, when cleaning floating objects on the water surface, the motor 524 away from the moving plate 51 is turned on, causing the winding roller 522 to rotate and wind the pull rope 523. At the same time, the motor 524 close to the moving plate 51 is turned on, causing the winding roller 522 to rotate and unwind the pull rope 523. This pulls the moving plate 51 to move. When the moving plate 51 comes into contact with the floating objects on the water surface during its movement, the floating objects are displaced to one side of the river channel, thus facilitating the retrieval and removal of the floating objects.

[0054] Example 2

[0055] like Figures 1-10 As shown, based on the above embodiments, this embodiment further provides the following:

[0056] In this embodiment, a groove 311 is provided on the side of the sealing plate 31 near the through hole 22. A movable plate 312 for sealing multiple through holes 22 is slidably installed on the sealing plate 31 and located in the groove 311. A receiving cavity 313 is provided on the sealing plate 31 and located below the groove 311. A second threaded rod 314 threadedly connected to the movable plate 312 is rotatably installed on the sealing plate 31. The bottom of the second threaded rod 314 extends into the receiving cavity 313. A third motor 315 for driving the second threaded rod 314 to rotate is fixedly installed in the receiving cavity 313. A cleaning component 6 for cleaning the through hole 22 is installed on the side of the movable plate 312 near the through hole 22. When the movable plate 312 slides in the groove 311, the cleaning component 6 cleans the inside of multiple through holes 22 in sequence.

[0057] When a small amount of water needs to be discharged from the river channel, the third motor 315 is controlled to rotate the second threaded rod 314, causing the movable plate 312 to move from the groove 311 to the outside of the cavity 21. This moves the movable plate 312 above the uppermost through hole 22. During this process, the cleaning component 6 can sequentially clean the interiors of multiple through holes 22. At this time, some water enters the groove 311 through the multiple through holes 22. Then, the first motor 33 is activated, and its output shaft rotates, driving the first threaded rod 314. 2. Rotate to make the sealing plate 31 slide outward in the cavity 21, so that the water in the groove 311 is discharged in reverse through multiple through holes 22, which has a secondary flushing and cleaning effect on the inside of multiple through holes 22. When the bottom of the sealing plate 31 moves above the through hole 22, the sealing of the through hole 22 can be removed, and the water can flow through the through hole 22 into the cavity 21 and be discharged through the drain hole 24. The cleaning component 6 cleans the inside of multiple through holes 22 in sequence to avoid blockage inside the through holes 22, which would affect the discharge of water.

[0058] In this embodiment, the cleaning component 6 includes a push plate 61. The movable plate 312 has a mounting hole 3121 on the side near the through hole 22. The push plate 61 is movably inserted through the mounting hole 3121 and can be inserted into the through hole 22. Springs 62 are symmetrically installed in the mounting hole 3121. The ends of the springs 62 are fixedly connected to the push plate 61. When the push plate 61 is hidden in the mounting hole 3121, the springs 62 are in a deformed state. The push plate 61 extends through the mounting hole 3121 to the outside of the mounting hole 3121 and is arc-shaped at one end.

[0059] In use, the third motor 315 is controlled to rotate the second threaded rod 314, causing the movable plate 312 to move from the groove 311 to the outside of the cavity 21. As the movable plate 312 moves to the top of the through hole 22, the movable plate 312 moves synchronously, causing the push plate 61 to move synchronously. When the push plate 61 moves to the through hole 22, the spring 62 returns to its natural state, pushing the push plate 61 into the through hole 22, so that the push plate 61 is inserted into the through hole 22, thereby achieving the cleaning effect inside the through hole 22. The end of the push plate 61 is arc-shaped, so it does not affect the sliding of the movable plate 312.

[0060] In this embodiment, a weeding mechanism 7 is installed at the bottom of the movable plate 51. The weeding mechanism 7 includes a mounting frame 71 fixedly installed at the bottom of the movable plate 51. A vertically oriented rotating shaft 72 is rotatably mounted on the mounting frame 71. Cutting blades 73 are fixedly mounted in a circular array at the bottom of the rotating shaft 72. The ends of the cutting blades 73 extend to the outside of the movable plate 51. A fourth motor 74 connected to the rotating shaft 72 is fixedly mounted on the mounting frame 71. A protective shell 75 is fixedly mounted on the top of the mounting frame 71 and sleeved on the outside of the fourth motor 74.

[0061] The design of the weeding mechanism 7 allows for the simultaneous activation of the fourth motor 74 while cleaning floating debris from the water surface. The operation of the fourth motor 74 drives the rotating shaft 72 to rotate on the mounting frame 71, which in turn drives the cutting blade 73 to rotate around the rotating shaft 72. As the moving plate 51 moves, it drives the weeding mechanism 7 to move synchronously, thereby cutting the aquatic plants in the river channel simultaneously through the cutting blade 73. The cut aquatic plants float to the surface of the water, and as the moving plate 51 moves, it pushes the cut aquatic plants to one side of the river channel for easy retrieval and cleaning.

[0062] Example 3

[0063] like Figures 1-10 As shown, based on the above embodiments, this embodiment further provides the following:

[0064] In this embodiment, a detection mechanism 8 is installed at the bottom of the movable plate 51 on the side of the mounting frame 71 away from the barrier plate 2. The detection mechanism 8 includes a connecting column 81 fixedly installed at the bottom of the movable plate 51, a bracket 82 fixed at the bottom of the connecting column 81, a detection impeller 83 rotatably installed inside the bracket 82, and a vertical rotating rod 84 rotatably installed on the movable plate 51. The rotating rod 84 and the detection impeller 83 are connected through a second bevel gear assembly 85, and the rotating rod 84 and the rotating shaft 72 are connected by a transmission component 86. The transmission component 86 adopts a belt drive assembly. In this embodiment, a background control system is also provided. The background control system is communicatively connected to the fourth motor 74. The background control system has a built-in monitoring module for real-time monitoring of the load of the fourth motor 74 under working conditions. The background control system is also communicatively connected to the first motor 33 and the second motor 43.

[0065] Utilizing the design of the detection mechanism 8, when the fourth motor 74 drives the rotating shaft 72 to rotate on the mounting frame 71, it drives the rotating rod 84 to rotate on the moving plate 51 through the transmission component 86. The second bevel gear assembly 85 drives the detection impeller 83 to rotate. When the height of the accumulated silt at the bottom of the river is higher than the bottom of the detection impeller 83, the detection impeller 83 rotates synchronously with the moving plate 51 during its movement. When the detection impeller 83 comes into contact with the silt, the rotational resistance of the detection impeller 83 increases, thereby increasing the load on the fourth motor 74. At this time, the background control system detects the increased load under the working state of the fourth motor 74, and thus controls the first motor 33 to open, so that the sealing plate 31 slides outward in the cavity 21, causing the bottom of the sealing plate 31 to move above the discharge hole 23. It also controls the second motor 43 to open. The second motor 43 drives the rotating shaft 42 to rotate through the first bevel gear assembly 44, thereby driving the cleaning plate 41 to rotate, achieving the effect of automatic cleaning of silt at the bottom of the river.

[0066] In this embodiment, the movable plate 51 is equipped with a toggle mechanism 9 connected to the barrier plate 2, which is used to toggle floating objects on the water surface on one side of the moving direction of the movable plate 51 away from the barrier plate 2.

[0067] By designing the actuating mechanism 9, floating objects on the water surface on one side of the moving plate 51 are moved away from the barrier plate 2, thereby effectively preventing the floating objects from accumulating and colliding with the barrier net 25 when the moving plate 51 moves and the floating objects move to the side of the river channel, thus facilitating the smooth movement of the moving plate 51 to the side of the river channel.

[0068] In this embodiment, the actuating mechanism 9 includes a first actuating assembly 91 and a second actuating assembly 92 respectively installed on both sides of the movable plate 51; the first actuating assembly 91 includes an actuating impeller 911 rotatably installed on one side of the movable plate 51, the outer wall of the actuating impeller 911 being able to fit against the barrier net 25, a rotating rod 912 rotatably installed on the side wall of the movable plate 51 near the actuating impeller 911, a gear 913 coaxially fixed to the bottom end of the rotating rod 912, and the top end being connected to the actuating impeller 911 through a third bevel gear assembly 914; the second actuating assembly 92 includes an actuating impeller 921 rotatably installed on the other side of the movable plate 51, actuating impeller 92 ... The outer wall of the second impeller 921 can be attached to the barrier net 25. The moving plate 51 is rotatably mounted with a rotating rod 922 near the side wall of the second impeller 921. The bottom end of the rotating rod 922 is coaxially fixed with a gear 923, and the top end is connected to the second impeller 921 through a fourth bevel gear assembly 924. The third bevel gear assembly 914 and the fourth bevel gear assembly 924 are symmetrically arranged. A rack plate 93 is fixedly installed on each of the multiple barrier plates 2. When two adjacent bases 1 are attached to each other on opposite sides, two adjacent rack plates 93 are attached to each other, and a transmission rack is formed through multiple rack plates 93. Gear 1 913 and gear 2 923 are both meshed with the transmission rack.

[0069] In use, when the movable plate 51 moves, it drives the rotating rod 912 and the rotating rod 922 to move synchronously, thereby driving the gears 913 and 923 to move synchronously. Since both gears 913 and 923 mesh with the transmission rack, the rotating rods 912 and 922 can be rotated on the movable plate 51 through the gears 913 and 923. This, in turn, drives the impeller 911 and the impeller 922 through the third bevel gear assembly 914 and the fourth bevel gear assembly 924. 921 rotates in opposite directions on the moving plate 51. When the moving plate 51 moves toward the first actuating impeller 911, it drives the first rotating rod 912 to rotate through the first gear 913. The third bevel gear assembly 914 causes the first actuating impeller 911 to rotate from bottom to top along the barrier plate 2. When the moving plate 51 moves toward the second actuating impeller 921, it drives the second rotating rod 922 to rotate through the second gear 923. The fourth bevel gear assembly 924 causes the second actuating impeller 921 to rotate from bottom to top along the barrier plate 2.

[0070] Working principle and usage process of this invention:

[0071] When using:

[0072] Multiple bases 1 are arranged in a horizontal linear array and fixed in the river channel, with adjacent bases 1 touching each other on opposite sides. A hydraulic cylinder 11 rotates the barrier plates 2 on the bases 1, so that the multiple barrier plates 2 are located on the same inclined surface, thus forming a hydraulic dam. Through the design of the through-hole 22, when a small amount of water needs to be discharged from the river channel, the first motor 33 is activated. The output shaft of the first motor 33 rotates, driving the first threaded rod 32 to rotate, which allows the sealing plate 31 to slide outwards or inwards within the cavity 21. When the bottom of the blocking plate 31 moves above the through hole 22, the blockage of the through hole 22 can be released, and the water source can flow through the through hole 22 into the cavity 21 and be discharged through the drain hole 24. This effectively prevents floating objects from flowing out of the barrier plate 2 when the hydraulic cylinder 11 rotates the barrier plate 2 on the base 1 for flood discharge. During this process, when controlling the movement of the blocking plate 31 to release the blockage of the through hole 22, the third motor 315 is first controlled to rotate the second threaded rod 314, causing the movable plate 312 to move from the groove 311 to the outside of the cavity 21. The movable plate 312 moves to the top of the through hole 22. During this process, the movable plate 312 moves, causing the push plate 61 to move synchronously. When the push plate 61 reaches the through hole 22, the spring 62 returns to its natural state, pushing the push plate 61 into the through hole 22, thus inserting the push plate 61 into the through hole 22 and cleaning the inside of the through hole 22. At this time, some water enters the groove 311 through multiple through holes 22, and then the first motor 33 is turned on. The output shaft of the first motor 33 rotates, driving the first... The threaded rod 32 rotates, causing the sealing plate 31 to slide outward within the cavity 21. This allows water in the groove 311 to be discharged in reverse through multiple through holes 22, providing a secondary flushing and cleaning effect to the inside of the multiple through holes 22. When the bottom of the sealing plate 31 moves above the through hole 22, the sealing of the through hole 22 can be removed, and water can flow through the through hole 22 into the cavity 21 and be discharged through the drain hole 24. The cleaning component 6 cleans the inside of the multiple through holes 22 in sequence to prevent blockage inside the through holes 22 from affecting the discharge of water.

[0073] When cleaning the silt at the bottom of the river, the first motor 33 is turned on, causing the sealing plate 31 to slide outward in the cavity 21, so that the bottom of the sealing plate 31 is moved above the discharge hole 23. Then the second motor 43 is turned on. The second motor 43 drives the rotating shaft 42 to rotate through the first bevel gear assembly 44, thereby driving the cleaning plate 41 to rotate. This pushes the silt accumulated at the bottom of the river near the discharge hole 23 into the discharge hole 23, and then discharges it through the cavity 21 and the discharge hole 24, thus achieving the effect of cleaning the silt.

[0074] When cleaning floating debris from the water surface, the motor 524 furthest from the moving plate 51 is turned on, causing the winding roller 522 to rotate and wind the pull rope 523. Simultaneously, the motor 524 closest to the moving plate 51 is turned on, causing the winding roller 522 to rotate and unwind the pull rope 523. This pulls the moving plate 51 to move. During the movement of the moving plate 51, when it comes into contact with the floating debris, the debris is displaced to one side of the river channel, making it easier to retrieve and remove the floating debris. For the next cleaning, both motors 524 are turned in opposite directions, which pulls the moving plate 51 to move in the opposite direction, displacing the floating debris to the other side of the river channel for easier use.

[0075] While cleaning floating debris from the water surface, the fourth motor 74 is simultaneously activated. The fourth motor 74 drives the rotating shaft 72 to rotate on the mounting frame 71, causing the cutting blade 73 to rotate around the rotating shaft 72. During the movement of the moving plate 51, the weeding mechanism 7 moves synchronously, allowing the cutting blade 73 to simultaneously cut the aquatic plants in the river channel. The cut aquatic plants float to the surface, and the moving plate 51 pushes the cut aquatic plants to one side of the river channel for easier retrieval and cleaning. During this process, as the fourth motor 74 drives the rotating shaft 72 to rotate on the mounting frame 71, the transmission component 86 drives the rotating rod 84 to rotate on the moving plate 51, which in turn drives the detection impeller 83 to rotate via the second bevel gear assembly 85. When the river channel... When the height of the sediment at the bottom is higher than the bottom of the detection impeller 83, the detection impeller 83 rotates and moves synchronously with the moving plate 51 during the movement of the moving plate 51. When the detection impeller 83 comes into contact with the sediment, the rotational resistance of the detection impeller 83 increases, thereby increasing the load on the fourth motor 74. At this time, the background control system detects the increased load on the fourth motor 74 and controls the first motor 33 to open, so that the sealing plate 31 slides outward in the cavity 21, causing the bottom of the sealing plate 31 to move above the discharge hole 23, and controls the second motor 43 to open. The second motor 43 drives the rotating shaft 42 to rotate through the first bevel gear assembly 44, thereby driving the cleaning plate 41 to rotate, achieving the effect of automatic cleaning of sediment at the bottom of the river.

[0076] During the movement of the movable plate 51, it drives rotating rod 912 and rotating rod 922 to move synchronously, thereby driving gear 913 and gear 923 to move synchronously. Since gear 913 and gear 923 mesh with the transmission rack, rotating rod 912 and rotating rod 922 can be rotated on the movable plate 51 through gear 913 and gear 923. This, in turn, drives impeller 911 and impeller 921 to rotate in opposite directions on the movable plate 51 through the third bevel gear assembly 914 and the fourth bevel gear assembly 924. When the movable plate 51 moves towards impeller 911, it drives rotating rod 912 through gear 913. When the first bevel gear 912 rotates, the first actuating impeller 911 rotates upward along the barrier plate 2 via the third bevel gear assembly 914. When the moving plate 51 moves towards the second actuating impeller 921, the second gear 923 drives the second rotating rod 922 to rotate. The fourth bevel gear assembly 924 causes the second actuating impeller 921 to rotate upward along the barrier plate 2, thereby actuating the floating objects on the water surface on one side of the moving plate 51 away from the barrier plate 2. This effectively prevents the floating objects from accumulating and colliding with the barrier net 25 when the moving plate 51 moves and shifts to the side of the river channel, thus facilitating the smooth movement of the moving plate 51 to the side of the river channel.
