Water conservancy river pollution ecological restoration device

Abstract

This invention relates to the field of ecological restoration technology, and more particularly to an ecological restoration device for polluted waterways. The bidirectional water flow interception module includes a support column fixedly connected to the riverbank. A guide frame is fixedly connected above the support column. Two sets of movable columns are slidably connected inside the guide frame. A rotating shaft is rotatably connected to the outer side of each movable column. An impurity separation plate is rotatably connected to the other end of each rotating shaft. A rotating mesh plate is fixedly connected to the other end of each impurity separation plate. When the water body flows bidirectionally in a tidal pattern, the rotating mesh plates on both sides of the module can adaptively rotate and adjust with the water flow direction, effectively intercepting floating debris. The vertical mesh plates with an arc-shaped structure guide floating debris to slide and collect on both sides, automatically converging into the impurity accumulation trough. When the water flows in the opposite direction during high tide, the working states of the rotating mesh plates on both sides automatically switch, effectively preventing floating debris from escaping through the mesh gaps, achieving continuous and stable capture of floating debris under bidirectional water flow conditions.

Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, specifically to an ecological restoration device for water conservancy and river pollution. Background Technology

[0002] In the field of river pollution ecological restoration, the removal of floating debris from the surface of flowing water is a crucial preliminary step. When conducting ecological restoration operations on flowing rivers, it is usually necessary to deploy surface interception mechanisms to centrally intercept and collect floating debris. While conventional interception structures can quickly collect and remove floating impurities, they are difficult to adapt to the specific operational needs of rivers with unique conditions.

[0003] Tidal channels are typical bidirectional flow channels. During high tide, seawater flows back in, creating a countercurrent, while during low tide, the river water flows out, creating a downstream flow, unlike the unidirectional constant flow of conventional rivers. Existing general-purpose unidirectional interception mechanisms, when applied to tidal channels, cannot adapt to the bidirectional flow characteristics of the water. This easily causes floating pollutants to be carried back by the high tide and accumulate repeatedly within the river section, making it difficult to achieve stable and effective interception and collection of floating debris. Therefore, to address the above problems, an ecological restoration device for water conservancy river pollution is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an ecological restoration device for polluted waterways, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, the water conservancy river pollution ecological restoration device includes a river embankment, a reinforcement wall and a two-way water flow interception module. Two sets of reinforcement walls are installed in the river channel of the river embankment, and a bidirectional water flow interception module that can adaptively adjust is installed between the reinforcement walls. An interception threshold is installed below each set of reinforced walls, and one side of the interception threshold is rotatably connected to the bidirectional water flow interception module. An adjustable, self-adjusting lifting platform is also installed between the two sets of reinforced walls; Each set of reinforced walls has a first blocking block and a second blocking block fixedly connected to one of their opposite ends; Impurity accumulation troughs are set up on both sides of the river in the center of the river embankment, and impurity lifting mesh plates are installed inside the troughs. One side of the impurity accumulation trough is connected to a flood discharge guide module, and the other end of the flood discharge guide module is connected to the river in the center of the river embankment. Lifting equipment is installed on both sides of the upper part of the river embankment, and the free ends of the lifting equipment are fixedly connected to the impurity lifting mesh. The bidirectional water flow interception module includes a support column fixedly connected to the river embankment. A guide frame is fixedly connected above the support column. Two sets of movable columns are slidably connected inside the guide frame, and a buffer mechanism is fixedly connected between the movable columns. A rotating shaft is rotatably connected to the outside of each movable column. An impurity removal plate is rotatably connected to the other end of each rotating shaft. A rotating mesh plate is fixedly connected to the other end of each impurity removal plate. The bottom of the rotating mesh plate is rotatably connected to the interception threshold.

[0006] As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, wherein: one side of the first blocking block is set with an inclined surface.

[0007] As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, a rectangular groove is provided in the center of the guide frame, and a through groove is provided on the side of the guide frame, and the moving column is slidably connected to the guide frame through the through groove.

[0008] As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, the number of impurity removal plates is two sets, and the impurity removal plates are arranged in an arc shape on the end face facing the rotating shaft.

[0009] Tidal channels are typical bidirectional flow channels. During high tide, seawater flows back in, creating a countercurrent, while during low tide, the river water flows out, creating a downstream flow, unlike the unidirectional constant flow of conventional rivers. Existing general-purpose unidirectional interception mechanisms, when applied to tidal channels, cannot adapt to the bidirectional reciprocating nature of the water flow. This easily causes floating pollutants to be carried back by the high tide, accumulating repeatedly within the river section, making it difficult to achieve stable and effective interception and collection of floating debris. This invention, through the deployment of a bidirectional water flow interception module, allows the rotating mesh plates on both sides of the module to adaptively rotate and adjust with the direction of the water flow when the water body is in a tidal bidirectional reciprocating flow. Under the action of the downstream water flow, one side of the rotating mesh plate deflects to an inclined state, allowing floating debris to smoothly pass over the inclined mesh plate; the other side of the rotating mesh plate remains vertical, effectively intercepting floating debris. Meanwhile, the impurity separation plate on one side of the vertical grid plate adopts an arc-shaped structure, which can guide the floating objects on the water surface to slide and collect to both sides, so that they automatically flow into the impurity accumulation tank; when the water flow is reversed and the tide rises, the working state of the rotating grid plates on both sides is automatically switched, effectively preventing the floating objects from escaping from the gaps in the grid, and realizing the continuous and stable capture of floating objects under bidirectional water flow conditions.

[0010] During the water flow reversal adjustment process, the first blocking block can limit and support the tilted rotating grid plate; the tilted rotating grid plate synchronously drives the rotating shaft, moving column and buffer mechanism to work together, thereby assisting the other rotating grid plate to maintain a vertical interception posture. The two sets of rotating grid plates form a mechanical linkage and always maintain an adaptive bidirectional interception condition.

[0011] After being intercepted by the rotating mesh plate, floating debris is collected in the debris accumulation trough under the guidance of the curved debris separation plate for centralized temporary storage. Subsequently, the debris lifting mesh plate can be driven upward by the lifting equipment to uniformly remove and dispose of the floating debris in the accumulation trough. When the tide recedes, the water in the debris accumulation trough can be returned to the river channel through the flood discharge module, effectively reducing the load on the lifting equipment and its operating energy consumption.

[0012] As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, the buffer mechanism includes a connecting column, both ends of which are fixedly connected to sliding discs, and the outer sides of the sliding discs are slidably connected to hollow sleeves, the outer sides of which are rotatably connected to the rotating shaft.

[0013] As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, a spring is fixedly connected to one side of the sliding disc, and the other end of the spring is fixedly connected to the hollow sleeve.

[0014] A buffer mechanism is installed between adjacent moving columns. When the river water flow velocity is high, the sliding disc compresses the matching spring to form a buffer and absorb energy, weakening the structural vibration caused by the water flow impact. At the same time, the connection between the connecting column, the sliding disc and the hollow sleeve ensures smooth transmission of the moving columns on both sides, making the linkage operation of the rotating grid plate more stable and reliable.

[0015] As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, the flood discharge and diversion module includes a diversion pipe, which is used to connect the impurity accumulation tank and the river channel in the center of the river embankment. A filter screen is fixedly connected to one end of the diversion pipe. A box is also installed on the outside of the diversion pipe. A rotating shaft is fixedly connected inside the box, and an interception plate is rotatably connected to the outside of the rotating shaft. A baffle plate is fixedly connected to the inner wall of the box on one side of the interception plate, and a support block is fixedly connected to the box on the other side of the interception plate.

[0016] As an optional embodiment of the water conservancy river pollution ecological restoration device described in this invention, the support block is inclined on the side facing the interception plate.

[0017] As an optional solution of the water conservancy river pollution ecological restoration device described in this invention, guide blocks are fixedly connected to both sides of the inner side of the box, and guide grooves are opened inside the guide blocks.

[0018] The flood discharge and diversion module has a one-way water-stopping function: during low tide, the water in the impurity accumulation tank flows into the box through the diversion pipe. The water flow pushes the interceptor plate to flip open and fit against the support block, realizing the smooth one-way outward discharge of water in the tank; when the tide rises and the river water level is higher than the liquid level in the impurity accumulation tank, the river water flows back into the box through the diversion pipe. The reverse water pressure pushes the interceptor plate to rotate in the opposite direction, sealing the water passage inside the box and effectively preventing the river tide from flowing back into the impurity accumulation tank.

[0019] Compared with the prior art, the beneficial effects of the present invention are: A bidirectional water flow interception module is deployed. When the water body flows in a tidal, bidirectional manner, the rotating mesh plates on both sides of the module can adaptively rotate and adjust with the direction of the water flow. Under the action of the forward water flow, one side of the rotating mesh plate deflects to an inclined state, allowing floating debris to smoothly pass over the inclined mesh plate; the other side of the rotating mesh plate remains vertical, effectively intercepting floating objects. At the same time, the impurity separation plate on the vertical mesh plate side adopts an arc-shaped structure, which can guide the floating objects on the water surface to slide and collect to both sides, automatically flowing into the impurity accumulation tank. When the water flows in the opposite direction with the rising tide, the working states of the two rotating mesh plates automatically switch, effectively preventing floating objects from escaping through the mesh gaps, achieving continuous and stable capture of floating objects under bidirectional water flow conditions, which contributes to river ecological restoration.

[0020] During the water flow reversal adjustment process, the first blocking block can limit and support the tilted rotating grid plate; the tilted rotating grid plate synchronously drives the rotating shaft, moving column and buffer mechanism to work together, thereby assisting the other rotating grid plate to maintain a vertical interception posture. The two sets of rotating grid plates form a mechanical linkage and always maintain an adaptive bidirectional interception condition.

[0021] A buffer mechanism is installed between adjacent moving columns. When the river water flow velocity is high, the sliding disc compresses the matching spring to form a buffer and absorb energy, weakening the structural vibration caused by the water flow impact. At the same time, the connection between the connecting column, the sliding disc and the hollow sleeve ensures smooth transmission of the moving columns on both sides, making the linkage operation of the rotating grid plate more stable and reliable.

[0022] After being intercepted by the rotating mesh plate, floating debris is collected in the debris accumulation trough under the guidance of the curved debris separation plate for centralized temporary storage. Subsequently, the debris lifting mesh plate can be driven upward by the lifting equipment to uniformly remove and dispose of the floating debris in the accumulation trough. When the tide recedes, the water in the debris accumulation trough can be returned to the river channel through the flood discharge module, effectively reducing the load on the lifting equipment and its operating energy consumption.

[0023] The flood discharge and diversion module has a one-way water-stopping function: during low tide, the water in the impurity accumulation tank flows into the box through the diversion pipe. The water flow pushes the interceptor plate to flip open and fit against the support block, realizing the smooth one-way outward discharge of water in the tank; when the tide rises and the river water level is higher than the liquid level in the impurity accumulation tank, the river water flows back into the box through the diversion pipe. The reverse water pressure pushes the interceptor plate to rotate in the opposite direction, sealing the water passage inside the box and effectively preventing the river tide from flowing back into the impurity accumulation tank.

Detailed Implementation

[0026] Example 1: Please refer to Figure 1 , Figure 4 and Figure 5 The present invention provides a technical solution: An ecological restoration device for water conservancy river pollution includes a river embankment 1, a reinforced wall 2, and a two-way water flow interception module 8; Two sets of reinforcement walls 2 are installed in the river channel of the river embankment 1. A bidirectional water flow interception module 8 that can be adaptively adjusted is installed between the reinforcement walls 2. An interception threshold 3 is installed below each set of reinforced walls 2, and one side of the interception threshold 3 is rotatably connected to the bidirectional water flow interception module 8. An adjustable self-adjusting lifting plate 11 is also installed between the two sets of reinforced walls 2; Each set of reinforced walls 2 has a first blocking block 6 and a second blocking block 9 fixedly connected to one of their opposite ends; Impurity accumulation troughs 10 are provided on both sides of the central river channel of the river embankment 1, and impurity lifting mesh plates 5 are installed inside the impurity accumulation troughs 10. One side of the impurity accumulation trough 10 is connected to a flood discharge guiding module 7, and the other end of the flood discharge guiding module 7 is connected to the river in the center of the river embankment 1. Lifting equipment 4 is installed on both sides above the river embankment 1, and the free ends of the lifting equipment 4 are fixedly connected to the impurity lifting mesh plate 5. The bidirectional water flow interception module 8 includes a support column 801 fixedly connected to the river embankment 1. A guide frame 802 is fixedly connected above the support column 801. Two sets of movable columns 803 are slidably connected inside the guide frame 802, and a buffer mechanism 807 is fixedly connected between the movable columns 803. A rotating shaft 804 is rotatably connected to the outside of each movable column 803. An impurity removal plate 805 is rotatably connected to the other end of each rotating shaft 804. A rotating mesh plate 806 is fixedly connected to the other end of each impurity removal plate 805. The bottom of the rotating mesh plate 806 is rotatably connected to the interception threshold 3.

[0027] The first blocking block 6 is set with one side inclined.

[0028] A rectangular groove is provided in the center of the guide frame 802, and a through groove is provided on the side of the guide frame 802. The moving column 803 is slidably connected to the guide frame 802 through the through groove.

[0029] There are two sets of impurity removal plates 805, and the end face of the impurity removal plate 805 facing the rotating shaft 804 is set in an arc shape.

[0030] Tidal channels are typical bidirectional flow channels. During high tide, seawater flows back in, creating a countercurrent, while during low tide, the river water flows out, creating a downstream flow, unlike the unidirectional constant flow of conventional rivers. Existing general-purpose unidirectional interception mechanisms, when applied to tidal channels, cannot adapt to the bidirectional reciprocating nature of the water flow. This easily causes floating pollutants to be carried back by the high tide and accumulate repeatedly within the river section, making it difficult to achieve stable and effective interception and collection of floating debris. This invention, through the deployment of a bidirectional water flow interception module 8, allows the rotating mesh plates 806 on both sides of the module to adaptively rotate and adjust with the direction of the water flow when the water body is in a tidal bidirectional reciprocating flow. Under the action of the downstream water flow, one side of the rotating mesh plate 806 deflects to an inclined state, allowing floating debris to smoothly pass over the inclined mesh plate; the other side of the rotating mesh plate 806 remains vertical, effectively intercepting floating debris. Meanwhile, the impurity separation plate 805 on one side of the vertical mesh plate adopts an arc-shaped structure, which can guide the floating objects on the water surface to slide and collect to both sides, so that they automatically flow into the impurity accumulation tank 10; when the water flow is reversed and the tide rises, the working state of the rotating mesh plates 806 on both sides is automatically switched, which effectively prevents the floating objects from escaping from the mesh gaps and realizes the continuous and stable capture of floating objects under bidirectional water flow conditions.

[0031] During the water flow reversal adjustment process, the first blocking block 6 can provide limiting support for the tilted rotating mesh plate 806; the tilted rotating mesh plate 806 synchronously drives the rotating shaft 804, the moving column 803 and the buffer mechanism 807 to work together, thereby assisting the other rotating mesh plate 806 to maintain a vertical interception posture. The two sets of rotating mesh plates 806 form a mechanical linkage and always maintain an adaptive bidirectional interception working condition.

[0032] After being intercepted by the rotating mesh plate, floating debris is collected in the impurity accumulation tank 10 under the guidance of the arc-shaped impurity separation plate 805 for centralized temporary storage. Subsequently, the impurity lifting mesh plate 5 can be driven upward by the lifting device 4 to uniformly remove and dispose of the floating debris in the accumulation tank. When the tide recedes, the water in the impurity accumulation tank 10 can be returned to the river channel through the flood discharge module 7, effectively reducing the load and operating energy consumption of the lifting device 4. The impurity lifting screen 5 is designed with a high center and low sides, which helps impurities move to both sides, facilitating subsequent treatment and contributing to river ecological restoration.

[0033] Also includes the following: The rotating mesh plate 806 of the bidirectional interception module 8 is provided with a first blocking block 6 and a second blocking block 9 on both sides. The second blocking block 9 is located on the outer side of the rotating mesh plate 806 to prevent it from rotating excessively outward, while the first blocking block 6 on the inner side is used to ensure that after the rotating mesh plate 806 rotates, the first blocking block 6 contacts one side of the rotating mesh plate 806 in the form of a surface. It not only serves the purpose of blocking and limiting, but also serves the purpose of supporting the rotating mesh plate 806 to prevent it from being damaged. The support column 801 adopts a vertical design and is used to support the guide frame 802 to prevent the silt accumulated at the bottom of the riverbed from affecting the normal use of the guide frame 802. A rectangular groove is provided on the top of the guide frame 802 for the rotating shaft 804 to move inside it, ensuring the smooth operation of the equipment. The rotating screen plate 806 is made of a hollow plate, which can block and filter floating objects on the water surface, thus intercepting floating objects. The bottom of the rotating screen plate 806 is rotatably connected to the interception threshold 3 to ensure that the rotating screen plate 806 rotates smoothly. At the same time, a debris removal plate 805 is also provided on one side of the rotating screen plate 806. Due to its arc-shaped design, when the water flow impacts the debris removal plate 805, one side of the debris removal plate 805 is arc-shaped and set in a straight line. At this time, it can help the water flow to both sides, thus providing assistance to propel the floating objects. At the same time, the debris removal plate 805 also serves to reinforce and support the rotating screen plate 806. The adaptive lifting plate 11 is used to adjust according to the water depth so that impurities entering the impurity accumulation tank 10 are less likely to escape.

[0034] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 6 Specifically, the buffer mechanism 807 includes a connecting column 8071, both ends of which are fixedly connected to a sliding disk 8072, and the outer side of the sliding disk 8072 is slidably connected to a hollow sleeve 8074, the outer side of the hollow sleeve 8074 being rotatably connected to the rotating shaft 804.

[0035] Springs 8073 are fixedly connected to one side of the sliding disk 8072, and the other end of the springs 8073 is fixedly connected to the hollow sleeve 8074.

[0036] A buffer mechanism 807 is installed between adjacent moving columns 803. When the river water flow velocity is high, the sliding plate 8072 compresses the matching spring to form a buffer and absorb energy, weakening the structural vibration caused by the water flow impact. At the same time, through the cooperation of the connecting column 8071, the sliding plate 8072 and the hollow sleeve 8074, the transmission of the moving columns 803 on both sides is ensured to be smooth, making the linkage operation of the rotating grid plate 806 more stable and reliable. The sliding disk 8072 is designed to ensure stable sliding inside the hollow sleeve 8074, preventing the connecting post 8071 from detaching from the hollow sleeve 8074.

[0037] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 2 and Figure 3 Specifically, the flood discharge and diversion module 7 includes a diversion pipe 701, which connects the impurity accumulation tank 10 and the river channel in the center of the river embankment 1. One end of the diversion pipe 701 is fixedly connected to a filter screen 702. A box 703 is also installed on the outside of the diversion pipe 701. A rotating shaft 704 is fixedly connected inside the box 703, and an interception plate 705 is rotatably connected to the outside of the rotating shaft 704. A baffle plate 706 is fixedly connected to the inner wall of the box 703 on one side of the interception plate 705, and a support block 707 is fixedly connected to the box 703 on the other side of the interception plate 705.

[0038] The support block 707 is inclined on the side facing the interceptor plate 705.

[0039] Guide blocks 708 are fixedly connected to both sides of the inside of the housing 703, and guide grooves are provided inside the guide blocks 708.

[0040] The flood discharge and diversion module 7 has a one-way water-stopping function: under low tide conditions, the water in the impurity accumulation tank 10 flows into the box 703 through the diversion pipe 701. The water flow pushes the interception plate 705 to flip open and fit against the support block 707, realizing the smooth one-way outward discharge of water in the tank; when the tide rises and the river water level is higher than the liquid level in the impurity accumulation tank 10, the river water flows back into the box 703 through the diversion pipe 701. The reverse water pressure pushes the interception plate 705 to rotate in the opposite direction, sealing the water passage inside the box 703, effectively preventing the river tide water from flowing back into the impurity accumulation tank; Also includes the following: When the impurity accumulation tank 10 discharges, the inclined surface of the support block 707 on one side contacts the side of the interceptor plate 705. This not only serves to block and limit the flow of water, but also to support the interceptor plate 705 and prevent it from being damaged. At the same time, when the interceptor plate 705 is impacted in the opposite direction, the inclined setting of the interceptor plate 705 helps it to reset. The box body 703 is also equipped with a guide block 708 to prevent the accumulation of silt and other impurities on one side of the box body 703 after the water passes through the interceptor plate 705, which helps some small impurities to be discharged smoothly. The designed filter screen 702 can filter larger impurities in the water to avoid affecting the water discharge. At the same time, the filter screen 702 adopts an arc surface design to increase the contact area and reduce the ability of impurities to adhere to the filter screen 702.
