Description

Technical Field

[0001] This application relates to the field of water conservancy gate technology, specifically to an ecological gate system. Background Technology

[0002] Currently, sluice gates, as hydraulic structures for regulating water levels and controlling flow, are widely used in river drainage projects. Due to the impact of domestic waste in the river and the slowing of water flow at the bottom of the sluice gate, a large amount of river waste is prone to float and accumulate at the front of the sluice gate, while the bottom of the riverbed will accumulate silt over the years. This effect is particularly pronounced for tidal gate systems in coastal areas of my country.

[0003] First, when the gate blocks water, a large amount of floating debris accumulates, making frequent manual dredging and cleaning difficult, costly, and posing safety hazards to the gate's operation. Second, when the gate drains water, the floating debris is easily spread by the water flow, polluting the marine ecological environment and adversely affecting the river water, seawater, and ecological landscape. Third, the gate is located at the junction of river water and seawater, and the silt at the bottom of the gate is difficult to clean in a timely manner, which can easily cause blockages during the opening and closing of the gate, affecting its normal opening and closing status.

[0004] In related technologies, the current gates are cleaned using trash racks or manual cleaning. Both require frequent manual intervention, otherwise floating debris will continue to accumulate at the front of the trash rack or gate for a long time. The bottom of the gate is usually cleaned by the gate's drainage process, but the number of times is limited and it is impossible to achieve the cleaning effect on time and with good quality.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0022] This application provides an ecological gate system that can solve the technical problems in related technologies, such as the need for frequent manual interception and cleaning of sewage and the inability to clean the bottom of the gate in a timely manner.

[0023] This application provides an ecological gate system to address the problems of floating debris accumulation and bottom siltation in river gate systems flowing into the sea. Tidal action is a periodic phenomenon of rising and falling tides. Most coastal areas of my country experience semi-diurnal tides with a cycle of approximately 12 hours. The maximum tidal range in Hangzhou Bay can reach 8 meters, containing a large amount of tidal potential energy. This application aims to rationally utilize the kinetic energy of river water and the tidal potential energy of seawater, and through hydraulic transmission and self-balancing of the gate structure, achieve adaptive and continuous ecological functions of the gate system for cleaning and dredging under different water conditions.

[0024] See Figure 1 and Figure 2 As shown, the ecological gate system includes: a water-blocking device 1, which has a river water end 111 and a seawater end 112, and a debris-blocking device 2 is provided at the river water end 111 of the water-blocking device 1; and a debris-cleaning device 3, which includes a debris-cleaning screen 31 and a floating box 35. One end of the debris-cleaning screen 31 is connected to the debris-blocking device 2, and the other end is connected to the floating box 35. The floating box 35 is located at the seawater end 112 of the water-blocking device 1. The two ends of the debris-cleaning screen 31 rise and fall with the water level changes of the seawater end 112 and the river water end 111 due to the buoyancy of the debris-blocking device 2 and the floating box 35. The dredging device 4 includes a dredging gate 411, a balance box 43, and a suspension system 42. The dredging gate 411 is located at the bottom of the water-blocking device 1. The balance box 43 is located at the seawater end 112. The suspension system 42 connects the balance box 43 and the dredging gate 411. The balance box 43 generates buoyancy changes with the water level at the seawater end 112, and the opening and closing of the dredging gate 411 is controlled by the suspension system 42.

[0025] See Figure 1 and Figure 2As shown, in this embodiment, the water-blocking device 1 mainly includes a main gate 11, a gate pier 12 and a bottom plate 13. The bottom plate 13 is arranged at the bottom of the main gate 11 and the gate pier 12. The bottom plate 13 is a reinforced concrete structure and is set on the riverbed at the bottom of the main gate 11. The groove on the bottom plate 13 matches the shape of the bottom of the main gate 11 and is provided with a water-stopping structure. The main gate 11 is a steel structure block and is arranged in the middle of the river channel. The gate pier 12 is a reinforced concrete structure and is arranged parallel to the direction of the river channel. In this embodiment, the gate pier 12 includes side piers 121, guide piers 122 and partition piers 123. The side piers 121 and guide piers 122 are arranged on opposite sides of the main gate 11 and are tightly fitted to the main gate 11. In this embodiment, it is preferable to provide grooves in both the side piers 121 and the guide piers 122. The two ends of the main gate 11 are inserted into the grooves to realize the connection between the main gate 11 and the side piers 121 and the guide piers 122. The main gate 11 divides the water-blocking device 1 into the river water end 111 and the sea water end 112. The partition pier 123 is arranged inside the guide pier 122 and divides the water environment of the guide pier 122 into the river water end 111 and the sea water end 112.

[0026] This embodiment incorporates a debris-blocking device 2, a debris-cleaning device 3, and a dredging device 4 into the water-blocking device 1. The debris-blocking device 2 guides floating debris to the debris-cleaning grid 31, which then transports the debris to the floating box 35, achieving automatic cleaning of the floating debris. Furthermore, the balance box 43 utilizes a hydraulically driven suspension system 42 to control the opening and closing of the dredging gate 411, thereby achieving dredging. This eliminates the need for frequent manual debris-blocking and cleaning, and solves the technical problems of related technologies where frequent manual debris-blocking and cleaning are required, and where timely dredging at the bottom of the gate is impossible. This embodiment leverages the environmental advantages of river flow dynamics and seawater tidal potential energy, employing hydraulic transmission and structural self-balancing effects to achieve the regular and sustainable operation of the gate's debris-blocking, debris-cleaning, and dredging ecological functions.

[0027] See Figure 2 As shown, the guide pier 122 includes an outer pier 1221 and an inner pier 1222. The seawater end 112 of the outer pier 1221 is connected to the inner pier 1222. The water environment between the outer pier 1221 and the inner pier 1222 is separated by a partition pier 123. The section connecting the river water end 111 is a cleaning pool 33, and the section connecting the seawater end 112 is a collection pool 34. The inner pier 1222 is arranged in a straight line, and the river water end 111 of the inner pier 1222 has a triangular structure. The angle is related to the arrangement of the floating belt 21. With the same orientation, the outer pier 1221 is located outside the inner pier 1222 and includes a straight section and an inclined section. The two ends of the outer pier 1221 away from the main gate 11 are straight sections, and the middle section of the outer pier 1221 near the debris interception device 2 is an inclined section. The inclination angle is consistent with the arrangement of the floating belt 21. The inclined section of the outer pier 1221 and the triangular structure at the front end of the inner pier 1222 form a channel entrance, which facilitates the coordinated guidance of the floating objects at the river end 111 into the cleaning pool 33 by the debris interception device 2.

[0028] Furthermore, in one embodiment, the debris-blocking device 2 includes a floating belt 21, a cleaning pipe 211 is provided in the floating belt 21, and the floating belt 21 is provided with a cleaning port 2111. The cleaning port 2111 is connected to the cleaning pipe 211. The floating belt 21 is connected to one end of the cleaning grid 31, and the cleaning pipe 211 is connected to the seawater end 112 through the cleaning grid 31.

[0029] See Figure 3 As shown, the debris interception device 2 in this embodiment includes a floating belt 21, a debris cleaning pipe 211, and a debris cleaning port 2111. The floating belt 21 is arranged at the river water end 111 of the main gate 11. The floating belt 21 is a flexible hollow round plastic tube structure that can float on the surface of the water. The cavity of the floating belt 21 is a water conveying channel composed of the debris cleaning pipe 211. The debris cleaning port 2111 is evenly arranged at a certain angle along the extension direction of the floating belt 21. The debris cleaning port 2111 is a hollow air nozzle structure and connects the debris cleaning pipe 211 with the surface water environment of the river water end 111. When the seawater end 112 is at high tide, it can guide seawater to flow down from the debris cleaning port 2111 to the river water end 111. Under the guidance of the inclined floating belt 21, the floating objects gathered at the front end of the gate are further pushed into the debris cleaning pool 33.

[0030] Furthermore, in some embodiments, the cleaning grid 31 includes a drive wheel 311, a driven wheel 312, and a transmission pipe 313 connecting the drive wheel 311 and the driven wheel 312. The driven wheel 312 is connected to the floating belt 21 and communicates with the cleaning pipe 211. The drive wheel 311 is communicated with the seawater end 112. The floating box 35 is located on one side of the drive wheel 311. Tracks 314 are provided outside the drive wheel 311 and the driven wheel 312, and the tracks 314 are provided with toothed rakes 3141.

[0031] See Figure 4 As shown, in this embodiment, the cleaning grid 31 is arranged in the internal cavity of the guide pier 122 and located at the river water end 111 of the partition pier 123. The river water end 111 of the cleaning grid 31 is connected to the debris blocking device 2. The seawater end 112 of the cleaning grid 31 is tilted upward and connected to the floating box 35. The floating box 35 is arranged in the internal cavity of the guide pier 122 and located at the seawater end 112 of the partition pier 123. The floating box 35 is tightly fitted with the cavity of the guide pier 122 and can move up and down within the cavity of the guide pier 122. The debris blocking device 2 and the cleaning device 3 form a hydraulic transmission and self-balancing state under the structural arrangement and buoyancy.

[0032] See Figure 4 and Figure 5As shown, the cleaning grid 31 is located above the cleaning pool 33 and includes a drive wheel 311, a driven wheel 312, and a transmission pipe 313. All three are hollow cylindrical structures. The drive wheel 311 is located at the seawater end 112 of the cleaning grid 31, and the driven wheel 312 is located at the river water end 111 of the cleaning grid 31. The transmission pipe 313 includes an arc-shaped section and a straight section. The arc-shaped section is connected to the ends of the drive wheel 311 and the driven wheel 312 near the outer pier 1221, respectively. The straight section connects the arc-shaped sections at both ends. The drive wheel 311, the driven wheel 312, and the transmission pipe 313 are tightly connected to form a water conveying channel. The track 314 is arranged on the outer wall of the drive wheel 311 and the driven wheel 312. The track 314 also includes a toothed rake 3141, which is evenly arranged perpendicular to the track 314.

[0033] Further, in one embodiment, rolling bearings are provided at the connection points of the transmission pipe 313 with the driving wheel 311 and the driven wheel 312, and blades 3111 are provided inside both the driving wheel 311 and the driven wheel 312; a main bearing 315 is provided at the end of the driving wheel 311 away from the transmission pipe 313; a balance bar 351 is fixedly provided in the floating box 35, and the balance bar 351 is engaged with the main bearing 315; the water-blocking device 1 is also fixedly provided with a limiting structure 352, which is located below the balance bar 351 and limits the height of the balance bar 351. Figure 7 (As shown).

[0034] See Figure 5 As shown, in this embodiment, the drive wheel 311 and driven wheel 312 are internally arranged with evenly distributed helical blades 3111. A rolling bearing is provided at the connection between the transmission tube 313 and the drive wheel 311 and driven wheel 312. The transmission tube 313 can extend into the inner wall of the drive wheel 311 and driven wheel 312 and remain in contact with the rolling bearing. The drive wheel 311 and driven wheel 312 can rotate freely around the outer wall of the transmission tube 313 with the support of the rolling bearing. The end of the drive wheel 311 closest to the main gate 11 extends outwards with a track 314. The extended portion of the drive wheel 311 is provided with a main... The inner wall of the main bearing 315 matches the outer diameter of the drive wheel 311. The water supply channel connecting the drive wheel 311 and the driven wheel 312 is connected through the transmission pipe 313. First, with the support of the main bearing 315 and the rolling bearing, the drive wheel 311 and the driven wheel 312 can rotate freely. Second, under the guiding effect of the transmission pipe 313, the potential energy of seawater can provide kinetic energy to the drive wheel 311 and the driven wheel 312 in sequence, improving the energy conversion efficiency. Third, it guides the seawater to smoothly enter the debris barrier 2, thereby connecting the hydraulic transmission channel from the seawater end 112 to the river water end 111.

[0035] See Figure 4As shown, the floating box 35 is located above the sludge collection tank 34 and floats on the surface of the water. The interior of the floating box 35 can store floating objects. The outer wall of the floating box 35 is tightly fitted with the cavity formed by the partition 123 and the guide 122. The floating box 35 can move up and down under the action of seawater buoyancy. The partition 123 and the floating box 35 prevent the water of the sludge collection tank 34 from communicating with the water of the cleaning tank 33, thus preventing uncontrolled water exchange between the river water end 111 and the seawater end 112. The floating box 35 is fixedly equipped with a balance bar 351, which is located at the front end of the floating box 35 and fixed to the side wall of the floating box 35. The top of the balance bar 351 has an arc-shaped cavity structure that matches the main bearing 315. The guide pier 122 is also fixedly equipped with a limiting structure 352, which is located on the inner pier 1222 at the bottom of the floating box 35. The limiting height is the same as the height of the partition pier 123. When the bottom of the balance bar 351 contacts the limiting structure 352, it can no longer descend. This can prevent the water level at the seawater end 112 from being too low during low tide, causing the floating box 35 to descend below the water level at the river water end 111, resulting in river water leakage or collision between the cleaning screen 31 and the partition pier 123. Through the buoyancy structure of the floating box 35 and the floating belt 21 and the transmission design of the balance bar 351, the cleaning device 3 can achieve adaptive balance under different water conditions and heights, and transfer the potential energy of the seawater to complete the hydraulic automatic cleaning during high tide.

[0036] In some alternative embodiments, see Figure 6 As shown, the water-blocking device 1 is provided with a cleaning meter hole 32. The cleaning meter hole 32 is provided with a flow guide 321 and an overflow gate 322. The overflow gate 322 is located on the side of the flow guide 321 close to the cleaning meter 31. The main bearing 315 is inserted into the cleaning meter hole 32 and the overflow gate 322 is stopped by the drive wheel 311.

[0037] In this embodiment, the cleaning surface orifice 32 is located at the seawater end 112 and is arranged on top of the guide pier 122. The cleaning surface orifice 32 connects the cleaning grid 31 with the water conveyance channel of the seawater end 112. The guide grid 321 is a grid structure and is arranged on the outermost side of the cleaning surface orifice 32. It serves two purposes: first, to block floating objects from interfering with the seawater end 112, and second, to adjust the seawater flow pattern to improve the diversion efficiency. The drive wheel 311 extends outward into the cleaning meter hole 32 near the main gate 11. The outer wall of the main bearing 315 matches the width of the cleaning meter hole 32. The main bearing 315 can move up and down within the cleaning meter hole 32. The drive wheel 311 can rotate freely within the cleaning meter hole 32 with the support of the main bearing 315. The overflow gate 322 is arranged in the cavity of the cleaning meter hole 32 and matches the outward extension position of the drive wheel 311 of the cleaning grid 31. The top of the overflow gate 322 is a circular arc cavity structure that matches the inner diameter of the drive wheel 311. The overflow gate 322 can be opened and closed up and down along the cleaning meter hole 32 to open or connect the water conveyance channel between the seawater end 112 and the cleaning grid 31.

[0038] Furthermore, in one embodiment, the bottom of the water-blocking device 1 is provided with a dredging bottom hole 41 connecting the river water end 111 and the seawater end 112. The dredging gate 411 is located in the dredging bottom hole 41. The suspension system 42 is installed on the water-blocking device 1. The balance box 43 is installed on the suspension system 42, and the balance box 43 is provided with a water inlet 432 and a dredging pipe 433. The dredging pipe 433 is connected to the dredging bottom hole 41. The balance box 43 drives the suspension system 42 to control the opening and closing of the dredging gate 411.

[0039] See Figure 9 As shown, the dredging bottom holes 41 are evenly arranged at the bottom of the main gate 11 and connect the inland river side and the sea side water. The dredging gate 411 is a steel structure block set in the dredging bottom hole 41. The bottom end and both sides of the dredging gate 411 are tightly fitted with the bottom plate 13 and the inner wall of the dredging bottom hole 41, respectively. The balance tank 43 is a hollow floating tank structure located at the seawater end 112 of the main gate 11. In this embodiment, the balance tank 43 is equipped with a fixing frame 431, which is the external support structure of the balance tank 43 and bears the weight of the balance tank 43 and the internal water. The water inlet 432 is located at the top of the balance tank 43, connecting the balance tank 43 with the seawater environment. The dredging pipe 433 is connected to the main gate 11 and extends to the outer wall of the dredging bottom hole 41. It connects the balance tank 43 with the hollow water environment of the dredging bottom hole 41 through the dredging port 4331. The vertical position of the dredging port 4331 is located at an appropriate distance from the bottom of the dredging gate 411 when it is fully open. After the dredging gate 411 is fully open, the water in the balance tank 43 is connected to the water environment of the dredging bottom hole 41 through the dredging pipe 433 and the dredging port 4331. In this embodiment, the potential energy of seawater stored in the balance box 43 is transmitted through the suspension system 42 during low tide, which helps the dredging device 4 to automatically open the dredging gate 411 and provide high-pressure water flow to clean the silt and sand accumulated at the bottom of the gate.

[0040] Further, in one embodiment, the suspension system 42 includes a plurality of vertical rods 421, horizontal rods 422, and cantilever arms 423. The vertical rods 421 are vertically inserted into the water-blocking device 1 and are connected to the sludge removal gate 411. The horizontal rods 422 are vertically hinged to the vertical rods 421, and one end of the cantilever arm 423 is vertically hinged to the horizontal rods 422. The other end of the cantilever arm 423 is connected to the balance box 43. The cantilever arm 423 is also provided with a central hinge point 426, which is located between the two ends of the cantilever arm 423, and the cantilever arm 423 is hinged to the water-blocking device 1 through the central hinge point 426.

[0041] See Figure 8 and Figure 10As shown, in this embodiment, the vertical rod 421, the horizontal rod 422, and the cantilever 423 are all cylindrical steel rod structures. A plurality of vertical rods 421 are evenly distributed and vertically arranged in the internal cavity of the main gate 11. The horizontal rod 422 is arranged horizontally and parallel to the end face of the main gate 11. The cantilever 423 is arranged horizontally and perpendicular to the end face of the main gate 11. The three form a three-axis solid geometry that is perpendicular to each other and intersects. The upper end of the vertical rod 421 extends outside the main gate 11 and is hinged to the horizontal rod 422 and the cantilever 423. The horizontal rod 422 is hinged to all the vertical rods 421 through the first hinge point 425. The end of the cantilever 423 near the river water end 111 is hinged to the horizontal rod 422 through the first hinge point 425. The end of the cantilever 423 near the seawater end 112 is hinged to the upper part of the balance box 43 through the second hinge point 427. One-third of the cantilever 423 near the seawater end 112 is hinged to the support 424 through the middle hinge point 426. The support 424 is fixed to the seawater end 112 outside the main gate 11, and its height is the same as the height of the first hinge point 425 and the second hinge point 427. The middle hinge point 426 also includes a bearing cylinder 4261. Figure 12 As shown), the bearing sleeve 4261 is a hollow sleeve structure and can slide along the cantilever 423. With the cooperation of the balance box 43 and the crossbar 422 at the first hinge point 425 and the second hinge point 427, they can rotate up and down around the middle hinge point 426, thereby driving all the vertical bars 421 to rise or fall inside the main gate 11.

[0042] Furthermore, in one embodiment, the top of the dredging gate 411 is further provided with an elastic pressure device 412, the top surface of the elastic pressure device 412 is attached to the water-blocking device 1, the bottom surface of the elastic pressure device 412 is connected to the dredging gate 411, and the vertical rod 421 passes through the elastic pressure device 412 and is connected to the dredging gate 411. See also Figures 9 to 11 As shown, in this embodiment, the elastic pressure device 412 is an elastic device with an internal cavity. Its lower end is connected to the upper end of the dredging gate 411, and its upper end is tightly fitted to the internal structure of the main gate 11. The elastic pressure device 412 can drive the dredging gate 411 to move up and down. The vertical rod 421 matches the internal cavity of the elastic pressure device 412 and passes through the elastic pressure device 412 to connect to the upper end of the dredging gate 411. In this embodiment, part of the closing force of the dredging gate 411 can be provided by the elastic pressure device 412.

[0043] Furthermore, in some embodiments, the water-blocking device 1 is provided with a locking groove 4213, and each vertical rod 421 has a locking hole 4212 at its bottom, with a lock head 4211 slidingly disposed in the locking hole 4212; when the sludge removal gate 411 is in the closed state, the lock head 4211 enters the locking groove 4213; when the vertical rod 421 drives the sludge removal gate 411 to rise, the locking hole 4212 drives the lock head 4211 to rise synchronously, and the lock head 4211 moves away from the locking hole 4212 under the guidance of the locking groove 4213 until the sludge removal gate 411 is fully opened.

[0044] See Figures 9 to 11 As shown, in this embodiment, the lower part of the vertical rod 421 is also provided with a lock hole 4212. The lock hole 4212 is a wedge-shaped cavity structure at the lower part of the vertical rod 421. The lock head 4211 is inserted into the lock hole 4212. The lock head 4211 is a steel structure block. The front end of the lock head 4211 corresponds to the lock hole 4212. The lock groove 4213 is an inclined cavity structure inside the main gate 11. The lock head 4211 can slide in the lock groove 4213. The sludge removal gate 411 is in the closed position. In the closed state, the lock head 4211 is fully inserted into the lock groove 4213 and is in a closed state. When the vertical rod 421 drives the sludge gate 411 to rise, the lock head 4211 rises synchronously under the action of the lock hole 4212. At this time, guided by the inclined lock groove 4213, the lock head 4211 continuously moves away from the lock hole 4212 until the sludge gate 411 rises to its maximum height, at which point the lock head 4211 completely disengages from the lock hole 4212, and the front end of the lock head 4211... The lock head 4211 changes from being inserted into the lock hole 4212 to having its front end abutting against the vertical rod 421. The design concept is that when the vertical rod 421 is in the rising state, the lock head 4211 applies pressure to the vertical rod 421 through its own weight. When the vertical rod 421 reaches its highest point, that is, after the sludge removal gate is fully opened, the lock head 4211 exits the lock hole 4212 under the inclined path design of the lock groove 4213, and no longer applies its own weight to the vertical rod 421. This facilitates the efficient use of the sludge removal water stored in the balance box 43. When the water in the balance box 43 is reduced to 1 / 4, the sludge removal ends. At this time, the vertical rod 421 tends to descend under the action of the elastic pressure device 412. After descending a short distance, the lock head 4211 returns to the lock hole 4212 and applies pressure to the vertical rod 421 through its own weight. Under the buffering effect of the elastic pressure device 412, the sludge removal gate 411 quickly returns to the bottom plate 13 to achieve the closed state.

[0045] In this embodiment, the hydraulic transmission and self-balancing state of the debris-blocking device 2 and the debris-cleaning device 3 are as follows: the floating box 35 rises and falls under the buoyancy of the seawater end 112, the balance bar 351 supports the driving wheel 311 in the main bearing 315, driving the seawater end 112 of the debris-cleaning screen 31 to move, the floating belt 21 rises and falls under the buoyancy of the river water end 111, the floating belt 21 supports the driven wheel 312, driving the river water end 111 of the debris-cleaning screen 31 to move, when a hydraulic potential energy difference is gradually formed between the seawater end 112 and the river water end 111, the debris-cleaning screen 31 tilts upward as a whole, opening the overflow. The flow gate 322 allows seawater to enter the water conveyance channel formed by the cleaning surface hole 32, the driving wheel 311, the transmission pipe 313, the driven wheel 312, and the floating belt 21 from the driving wheel 311. This drives the blades 3111 in the driving wheel 311 and the driven wheel 312 to operate the cleaning screen 31, which is a hydraulic transmission state. The floating box 35, the cleaning screen 31, and the floating belt 21 follow the water level changes at the seawater end 112 and the river water end 111, and maintain the height matching between the floating objects in the cleaning pool 33 and the floating box 35 on the collection pool 34, which is a self-balancing state. The hydraulic transmission and self-balancing state of the dredging device 4 is as follows: Under the action of seawater buoyancy and internal load, the balance box 43, according to the height difference between the seawater end 112 and the river water end 111, transmits hydraulic potential energy through the suspension to adaptively drive the opening and closing process of the dredging gate 411 under different water conditions, which is a hydraulic transmission and self-balancing state. This application fully leverages the environmental advantages of river flow dynamics and seawater tidal potential energy, innovates the structural layout and hydraulic transmission operation mode of the gate system, and coordinates with the relative rise and fall of sea level and horizontal plane under tidal phenomena to realize the gate system towards functional ecology, low-carbon power, and circular operation. Through the concept of hydraulic transmission and structural operation self-balancing, the ecological gate system is endowed with the functions of water blocking, drainage, pollution removal, and silt removal.

[0046] This application introduces a debris-blocking device 2, a debris-cleaning device 3, and a dredging device 4 into the traditional sluice gate. Firstly, it fully utilizes the kinetic energy of water flow and the potential energy of ocean tides during the sluice gate's drainage process. On one hand, it uses the potential energy of the water body to recover and clean floating debris; on the other hand, it uses the kinetic energy of surging waves and the potential energy of river water to simultaneously create an efficient dredging environment, replacing traditional manual or mechanical methods and thus possessing greater energy-saving and low-carbon development significance. Furthermore, this embodiment utilizes the periodic water level potential energy difference between seawater and river water under ocean tides. Through the self-balancing structure and operation of the sluice gate floating box 35-debris-cleaning grate 31-floating belt 21, balance box 43-suspension-dredging gate 411, it achieves the sluice gate's ability to regularly utilize hydraulic transmission to drive the debris-cleaning and dredging functions sustainably under different water conditions, thus possessing greater ecological and environmental protection prospects. Meanwhile, the debris interception device 2, debris removal device 3, and dredging device 4 of this application all adopt a modular design, which forms a good complementary effect with the reinforced concrete or steel structure of the water blocking device 1 in terms of construction, operation and maintenance. The former can be prefabricated, modularly inspected and replaced over the long service life of the latter, which is conducive to improving construction efficiency and ensuring the convenience of later maintenance.

[0047] The operation mode of the ecological gate system in this embodiment includes the following steps: S1. Initial state: When the water level at the seawater end 112 is similar to that at the river water end 111, the main gate 11 is closed, the overflow gate 322 is closed, the dredging gate 411 is closed, the balance box 43 is unloaded, and the closing force of the dredging gate 411 is provided by the lock head 4211 and the elastic pressure device 412.

[0048] S2, Energy Storage Process of Cleaning and Balancing Box 43: A large amount of floating debris accumulates at the river water end 111 of the main gate 11. When the seawater end 112 rises to a high water level, thanks to the self-balancing effect of the debris-blocking device 2 and the cleaning device 3, the floating belt 21, the cleaning screen 31, and the floating box 35 maintain a highly matched state. This allows the floating debris in the cleaning pool 33 to be transferred to the floating box 35 on the collection pool 34. The overflow gate 322 is opened. Thanks to the hydraulic transmission effect of the debris-blocking device 2 and the cleaning device 3, the cleaning process can be powered on the basis of self-balancing. Specifically, the overflow gate 322 opens and descends to a height matching the height of the drive wheel 311. Firstly, the seawater passes through the guide screen 321 to adjust the flow pattern and clean the floating debris. Secondly, the seawater... The drive wheel 311, transmission pipe 313, and driven wheel 312 are driven to propel the spiral blades 3111, providing kinetic energy for the rotation of the drive wheel 311 and driven wheel 312. The drive wheel 311 and driven wheel 312 rotate rapidly under the support of the bearings on both sides, driving the track 314 and toothed rake 3141 on the cleaning grid 31 to move. Thirdly, seawater enters the cleaning pipe 211 of the floating belt 21 and is discharged to the river end 111 through the cleaning port 2111. The floating objects at the river end 111 are pushed into the cleaning pool 33 by the water flow angle setting. Under the action of the track 314 and toothed rake 3141, the floating objects in the cleaning pool 33 are transferred to the floating box 35 on the collection pool 34 for storage. When the cleaning process is over, the overflow gate 322 is closed.

[0049] When the seawater end 112 is at a high water level, the balance box 43 is pushed upward by the buoyancy of the seawater on the second hinge point 427. Under the lever action of the cantilever 423 and the middle hinge point 426, it applies downward pressure to the crossbar 422. The crossbar 422 distributes the pressure evenly to all the vertical bars 421, and then transmits it to the bottom sludge gate 411. With the weight of the lock head 4211 and the elastic pressure device 412, it applies a greater closing force to the sludge gate 411. When the seawater submerges the water inlet 432 of the balance box 43, the balance box 43 is filled with water. During the filling process, the buoyancy of the balance box 43 gradually decreases, and the closing force of the sludge gate 411 is provided by the weight of the lock head 4211 and the elastic pressure device 412. Thus, the cleaning and energy storage process of the balance box 43 is completed.

[0050] S3. Dredging and Energy Release Process of Balance Box 43: A significant amount of silt accumulates at the river water end 111 of the main gate 11. When the seawater end 112 recedes to a low water level, the balance box 43 gradually applies downward pressure to the second hinge point 427. Under the lever action of the cantilever 423 and the middle hinge point 426, an upward pulling force is applied to the crossbar 422. The crossbar 422 evenly distributes the pulling force to all the vertical bars 421, which is then transmitted to the dredging gate 411 at the bottom of the vertical bars 421. As the sea level drops... When the water level reaches one-quarter of the distance from the bottom of the balance box 43, the tension of the balance box 43 on the vertical rod 421 is equal to the weight of the lock head 4211. At this point, the closing force of the dredging gate 411 is mainly provided by the elastic pressure device 412. As the height of the seawater end 112 continues to decrease, the elastic pressure device 412 begins to deform and compress, and the dredging gate 411 slowly rises. The river water end 111 tends to flow towards the seawater end 112. When the sea level continues to drop to the bottom of the balance box 43, the elastic pressure device 412 is completely deformed. The dredging gate 411 rises to the top of the cavity above the dredging bottom hole 41. Driven by the locking hole 4212 at the bottom of the vertical rod 421, the lock head 4211 rises to the top of the cavity above the lock head 4211 and falls out of the locking groove 4213. The lock head 4211 no longer provides pressure to the vertical rod 421, and the dredging port 4331 is no longer obstructed by the side wall of the dredging gate 411 in its closed state. At this time, the dredging gate 411 is fully open, and the dredging pipe 433 connects the balance box 43 with the water environment of the dredging port 4331. (Seawater end 1) When the swell impacts the dredging outlet 4331, the pressure rises sharply and generates a water hammer effect, which lifts the silt at the bottom of the main gate 11. After the swell recedes, the pressure at the dredging outlet 4331 drops. Combined with the high pressure at the river water end 111, the hydrodynamic environment created by the sea water end 112 and the river water end 111 discharges the disturbed silt from the dredging bottom hole 41 to the sea water end 112. At the same time, the water flow transported by the balance box 43 further cleans the silt at the bottom of the main gate 11 and the dredging gate 411.

[0051] S4. Return to initial state: When the balance box 43 is filled with less than 1 / 4 water after water flushing, the elastic pressure device 412 begins to deform and stretch. The vertical rod 421 only needs to move down slightly, and the lock head 4211 can return to the lock groove 4213 and reapply the self-weight of the lock head 4211 to the vertical rod 421. At this time, the sludge removal gate 411 closes quickly and returns to the initial state under the buffering effect of the elastic pressure device 412.

[0052] In summary, this application addresses two main points: First, it integrates the functions of cleaning and dredging in a gate system by combining seawater tidal phenomena with river water regulation needs, providing a low-carbon, energy-saving, and sustainable ecological function for traditional gate chambers during water blocking and drainage. Second, it designs a composite and integrated structural layout for the gate system. Through the hydraulic transmission and self-balancing design of the debris-blocking device 2, the debris-cleaning device 3, and the dredging device 4, it provides operational assurance for the gate system to perform cleaning work under complex water conditions. The suspension-type opening and closing design of the dredging device 4 provides operational assurance for the gate system to adaptively store and release seawater potential energy to complete the dredging work. The overall structure operates in a regular manner, performing cleaning and dredging sequentially during high and low tides, fully leveraging the ecological engineering advantages of "water-based water management," and possessing broad development prospects and application value.
