Description

Technical Field

[0001] This application relates to the field of hydraulic gate technology, specifically to a hydraulic energy storage type tide gate system and control method. Background Technology

[0002] Tide gates are widely used in coastal areas of my country, serving to block tides and drain water. During high tide, the gates are closed to prevent tidal water from flowing back into the river channel; during low tide, they can release floodwater, drain waterlogged areas, and flush away silt.

[0003] Tide gates currently suffer from problems such as the accumulation of floating debris and siltation at the bottom. As river water carries a large amount of domestic waste, marine debris also tends to accumulate near the gate. Furthermore, the slowed water flow at the bottom of the gate chamber causes siltation. This pollution from floating debris and siltation seriously affects the river and marine ecological environment and poses a significant threat to the normal operation of the tide gate.

[0004] In related technologies, current tide gates generally use trash racks and manual cleaning. The former requires a large investment and is complicated to operate, while the latter has a long cleaning cycle, is slow to take effect, and has safety issues.

[0005] Therefore, it is necessary to design a new hydraulic energy storage tide gate system to overcome the above problems. Summary of the Invention

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 a hydraulic energy storage tide gate system and control method, which can solve the technical problems of large investment or safety issues in related technologies.

[0023] See Figure 1 and Figure 2As shown, a hydraulic energy storage tide gate system provided in this application embodiment may include: a gate chamber module 1, which includes a gate chamber I 11, a gate chamber II 12, and a functional chamber 13. The gate chamber I 11 is connected to the gate chamber II 12 and is located on one side of the gate chamber II 12. The functional chamber 13 is connected to the gate chamber I 11 and the gate chamber II 12 and is located on the same side of the gate chamber I 11 and the gate chamber II 12; and a hydraulic transmission module 2, which includes a debris-blocking device 21, a debris-cleaning device 22, a silt-flushing device 23, and a connecting device 24. The debris-blocking device 21 is provided in both the gate chamber I 11 and the gate chamber II 12. The debris-cleaning device 22 is located between the gate chamber I 11 and the functional chamber 13, and between the gate chamber II 12 and the functional chamber 13. The silt flushing device 23 is located at the connection between the functional chamber 13 and the gate chamber I 11, and at the connection between the functional chamber 13 and the gate chamber II 12. The connecting device 24 connects the gate chamber I 11, the gate chamber II 12, and the functional chamber 13. The debris blocking device 21 and the debris cleaning device 22 are configured to collect floating debris by water flow. The control module 3 includes a valve group 31 located in the connecting device 24 and a gate group 32 located in the silt flushing device 23. The control module 3 also includes a controller and a signal collector. The controller is connected to the signal collector and is used to control the opening and closing states of the valve group 31 and the gate group 32 according to the height information collected by the signal collector.

[0024] See Figure 1 and Figure 2 As shown, in this embodiment, the gate chamber module 1 is a reinforced concrete structure. Gate chamber I 11 and gate chamber II 12 are connected end to end. Gate chamber I 11 is arranged at the river water end and connected to the river level 111. Gate chamber II 12 is arranged at the sea water end and connected to the sea level 121. Functional chamber 13 is arranged outside gate chamber I 11 and gate chamber II 12 and connected to the water storage surface 131. The river level 111, the sea level 121 and the water storage surface 131 all represent the water level height of the water environment in the gate chamber.

[0025] This embodiment features gate chamber I 11, gate chamber II 12, and functional chamber 13. Gate chamber I 11 is connected to the river level 111, and gate chamber II 12 is connected to the sea level 121. A signal acquisition device can collect the heights of the river level 111 and the sea level 121. During high tide, the valve group 31 is opened and the gate group 32 is closed, connecting gate chamber I 11, gate chamber II 12, and functional chamber 13 via the connecting device 24. This allows water flow to drive the debris-blocking device 21 and the debris-cleaning device 22 for debris removal, while the functional chamber 13 stores energy. The gate group 31 is controlled by... When valve group 32 is opened and valve group 31 is closed, gate chamber II 12 can be connected to functional chamber 13 to achieve dredging. When the tide recedes, by controlling valve group 31 to open and gate group 32 to close, gate chamber I 11 and gate chamber II 12 can be connected through the connecting device 24, thereby driving the debris barrier 21 and debris removal device 22 to remove debris. By controlling gate group 32 to open and valve group 31 to close, gate chamber I 11 can be connected to functional chamber 13 to achieve dredging. There is no need to use debris barriers and manual debris removal, which solves the technical problems of large investment or safety issues in related technologies.

[0026] This embodiment of the hydraulic energy storage tidal gate system is an upgrade and modification of the traditional gate chamber, possessing strong compatibility and portability. Both the hydraulic transmission module 2 and the control module 3 adopt a modular design, facilitating the inspection and maintenance of individual components during subsequent operation. Furthermore, the gate chamber module 1 incorporates a tidal energy storage space (i.e., functional room 13), storing the hydraulic potential energy during high tide as a stable and reliable power source for the tidal gate's cleaning and dredging functions. The hydraulic transmission module 2 transmits the stored hydraulic potential energy to the cleaning device 22 and the dredging device 23 via a connecting device 24. With the cooperation of the control module 3, the hydraulic energy storage and release are rationally guided, thereby driving the tidal gate to cyclically operate its cleaning, water purification, and dredging functions under different water level conditions. Compared to traditional manual cleaning, dredging, or mechanical dredging methods, this system can continuously operate with the ebb and flow of the tide, creating favorable conditions for cleaning and dredging and enabling regular and continuous operation. It fully utilizes the green and renewable energy of tidal energy, achieving clean, efficient, and ecologically and engineeringly coupled benefits of water-based water management.

[0027] Further, in one embodiment, the gate assembly 32 includes a main gate 321, a silt flushing gate I 322, and a silt flushing gate II 323. The silt flushing gate I 322 and the silt flushing gate II 323 are disposed on the silt flushing device 23, and the main gate 321, the silt flushing gate I 322, and the silt flushing gate II 323 are all connected to the controller; the gate chamber module 1 includes a gate pier 14 and a base plate 15. The base plate 15 is disposed at the bottom of the gate pier 14, and the gate pier 14 includes a side pier 141 and a guide pier 14. 2. Functional pier 143 and energy storage pier 144, the functional pier 143 and the energy storage pier 144 together with the base plate 15 form the functional chamber 13. The flow guide pier 142 and the side pier 141 are located on the same side of the functional pier 143, and the main gate 321 is provided between the flow guide pier 142 and the side pier 141. The main gate 321 divides the gate chamber formed by the flow guide pier 142, the side pier 141 and the base plate 15 into gate chamber I 11 and gate chamber II 12.

[0028] See Figure 1 As shown, in this embodiment, gate chamber I 11 and gate chamber II 12 are connected or separated by a main gate 321. Gate piers 14 are arranged parallel to the river channel direction. A base plate 15 is set on the riverbed at the bottom of the main gate 321 and gate piers 14. The bottom and sides of the main gate 321 are tightly fitted to the base plate 15 and gate piers 14, respectively, and can be sealed using a rubber sealing process. In this embodiment, gate piers 14 include side piers 141, guide piers 142, functional piers 143, and energy storage piers 144. Side piers 141 and guide piers 142 are located on both sides of the main gate 321. A sliding groove is provided at the connection between the side piers 141 and guide piers 142 and the main gate 321, allowing the main gate 321 to slide vertically along the groove, facilitating its raising and lowering for opening and closing, thereby connecting or separating the water environment of gate chamber I 11 and gate chamber II 12. The two ends of the side piers 141 also include vertically arranged strip-shaped limiting grooves 1411 (…). Figure 2 As shown in the figure, this facilitates the restriction of the lifting and lowering movement of one end of the debris-blocking device 21 as it floats on the water surface at a fixed node. The two ends of the guide pier 142 are wedge-shaped structures, and the guide pier 142 is connected to the functional pier 143.

[0029] In the above embodiments, the debris interception device 21, debris removal device 22, silt flushing device 23 and connecting device 24 of the hydraulic transmission module 2 are symmetrically arranged along the main gate 321, that is, a set of structures is provided at the river level 111 and the sea level 121. The symmetrical arrangement can maintain the consistency of various structures, which is conducive to batch production of the same model and simplifies the installation process.

[0030] Furthermore, in some embodiments, the cleaning device 22 includes a cleaning machine 221, a collection platform 224, a collection area I 222, and a collection area II 223. The cleaning machine 221 is located between the guide pier 142 and the functional pier 143. The collection platform 224 is located on the functional pier 143. One end of the cleaning machine 221 is connected to the debris blocking device 21, and the other end extends obliquely to the collection platform 224. The collection area I 222 is formed between the side of the guide pier 142 near the gate chamber I 11 and the functional pier 143. The collection area II 223 is formed between the side of the guide pier 142 near the gate chamber II 12 and the functional pier 143.

[0031] See Figure 1 and Figure 5 As shown, in this embodiment, the cleaning machine 221 is disposed between the guide pier 142 and the functional pier 143, and the sludge collection platform 224 is disposed on the functional pier 143. The top of the sludge collection platform 224 is open, and two cleaning machines 221 are symmetrically disposed on both sides of the sludge collection platform 224. One cleaning machine 221 is disposed at the sludge collection area I 222, and the other cleaning machine 221 is disposed at the sludge collection area II 223. The debris blocking device 21 guides the floating objects into the sludge collection area I 222 and the sludge collection area II 223. The cleaning machines 221 at the sludge collection areas I 222 and II 223 both extend upwards to the top of the sludge collection platform 224. The cleaning machines 221 can collect the floating objects in the sludge collection areas I 222 and II 223 into the sludge collection platform 224. Among them, the sewage collection area I 222 is the river level 111 area formed between the river water side guide pier 142 and the functional pier 143, and the sewage collection area II 223 is the sea level 121 area formed between the sea water side guide pier 142 and the functional pier 143.

[0032] Preferably, the functional pier 143 includes a straight pier 1432 and inclined piers 1433 located at both ends of the straight pier 1432. The straight pier 1432 is parallel to the guide pier 142, and the cleaning device 22 is disposed between the straight pier 1432 and the guide pier 142. The inclined piers 1433 are inclined in the same direction as the debris-blocking device 21. See also Figure 2As shown, the functional pier 143 includes a straight pier 1432 and an inclined pier 1433. The straight pier 1432 is in the middle, and the inclined pier 1433 has a straight section on the side away from the straight pier 1432. The inclination angle of the inclined pier 1433 is consistent with the direction of the debris-blocking device 21. The straight pier 1432 in the middle of the functional pier 143 has a reserved working groove 1431. The working groove 1431 is a square groove structure. The debris collection platform 224 is set inside the working groove 1431. The wedge-shaped structures at both ends of the guide pier 142 and the inclined pier 1433 of the functional pier 143 form a channel opening. With the cooperation of the debris-blocking device 21, it is convenient to guide floating objects into the debris collection area I 222 and the debris collection area II 223. The functional pier 143 and the energy storage pier 144 form the outer wall of the functional chamber 13. The gate chamber module 1 can be combined with the above basic structure and arranged according to the actual situation.

[0033] Further, in one embodiment, the debris-blocking device 21 includes a floating belt 211, which has a cavity inside. The bottom of the floating belt 211 is provided with a water inlet 212, and the top is provided with a cleaning hole 213. The cleaning hole 213 faces the debris collection area I 222 and the debris collection area II 223. The connecting device 24 includes a guide pipe 243, which has a first interface, a second interface, and a third interface that are connected to each other. The first interface is connected to the floating belt 211 of the gate chamber I 11, the second interface is connected to the floating belt 211 of the gate chamber II 12, and the third interface is connected to the functional chamber 13.

[0034] See Figure 3 and Figure 4 As shown, in this embodiment, the debris-blocking device 21 floats on the river surface 111 and sea surface 121 at both ends of the main gate 321. The debris-blocking device 21 includes a floating belt 211, which is preferably a hollow plastic tube structure. The water inlet 212 is set at the bottom of the floating belt 211, connecting the lower water body of the river surface 111 with the internal cavity of the floating belt 211 of the gate chamber I 11, and connecting the lower water body of the sea surface 121 with the internal cavity of the floating belt 211 of the gate chamber II 12. The debris-cleaning hole 213 is set at the water-facing end of the floating belt 211 away from the main gate 321. The opening of the debris-cleaning hole 213 faces the functional pier 143 and connects the surface water body of the river surface 111 with the internal cavity of the floating belt 211 of the gate chamber I 11, and connecting the surface water body of the sea surface 121 with the internal cavity of the floating belt 211 of the gate chamber II 12.

[0035] In this embodiment, the debris-blocking device 21 can float up and down with the rise and fall of the water level. The end of the debris-blocking device 21 away from the main gate 321 is located in the strip-shaped limiting groove 1411, and the end close to the main gate 321 is attached to the side of the guide pier 142 and connected to the top of the cleaning machine 221. During the floating process, the floating belt 211 is constrained by the rotation radius of the strip-shaped limiting groove 1411 and the cleaning machine 221, and can always be in the preset position of the side pier 141 and the guide pier 142. In addition, the water inlet 212 draws water from the lower water body, which can avoid the influence of floating objects in the surface water. The cleaning hole 213 sprays water towards the surface water of the debris collection area I 222 and debris collection area II 223. With the tilt direction of the floating belt 211, it can push the floating objects to gather in the debris collection area I 222 and debris collection area II 223, thereby fully ensuring the debris-blocking effect under different water level conditions.

[0036] See Figure 9 As shown, in this embodiment, the third interface of the guide pipe 243 is inserted into the functional chamber 13, and the first and second interfaces are directly or indirectly connected to the floating belt 211, so that the sea level 121, the water storage surface 131 and the river level 111 can form a guide loop through the guide pipe 243 and the debris interception device 21.

[0037] Further, in one embodiment, the cleaning machine 221 includes a main impeller 2211 and a driven impeller 2214. The main impeller 2211 and the driven impeller 2214 are provided with a track 2217. The main impeller 2211 is a hollow cylindrical structure and is located at the end of the track 2217 away from the sludge collection platform 224. The main impeller 2211 is provided with a drive shaft 2212 and a main blade 2213. The driven impeller 2214 is provided with a driven shaft 2215 and a driven blade 2216.

The second interface is connected to the floating belt 211 of the gate chamber II 12 through the main impeller 2211 on the gate chamber II 12 side.

[0038] See Figure 5 and Figure 6As shown, in this embodiment, the cleaning machine 221 includes a main rotor 2211, a driven rotor 2214, and a track 2217. The main rotor 2211 is a hollow cylindrical structure located at the end of the cleaning machine 221 away from the main gate 321. The main rotor 2211 contains a drive shaft 2212 and main blades 2213. The drive shaft 2212 is located at the axis of the internal cavity of the main rotor 2211. The main blades 2213 are adjustable propeller structures, with their bottom connected to the outer wall of the drive shaft 2212 and their top connected to the main rotor. The inner wall of 2211 is connected, and the main blade 2213 can rotate around the bottom and top connection points. The driven wheel 2214 is also a hollow cylinder structure, located at one end of the cleaning machine 221 near the main gate 321. The driven wheel 2214 is equipped with a driven shaft 2215 and a driven blade 2216. The driven shaft 2215 is located at the axis of the internal cavity of the driven wheel 2214.

In this embodiment, the end of the cleaning machine 221 furthest from the main gate 321 is connected to the debris-blocking device 21. The main impeller 2211 and the floating belt 211 are tightly connected to form a water conveyance channel (and the main impeller 2211 is connected to the guide pipe 243). The water flow impacting the main blades 2213 drives the main impeller 2211 and the track 2217 to move. By adjusting the angle of the main blades 2213 to rotate 180°, the rotation direction of the main impeller 2211 can be kept consistent after the water flow direction is reversed. The track 2217 is arranged on the outer wall of the main impeller 2211 and the driven impeller 2214. The toothed rakes 2218 are evenly arranged perpendicular to the track 2217 to improve the efficiency of transporting floating objects.

[0039] In this embodiment, a driven shaft 2215 and a bearing are fixed at one end of the cleaning machine 221 near the collection platform 224. The driven shaft 2215 is restricted to rotate within the bearing. The cleaning machine 221 can rotate around the driven shaft 2215 as its axis. After being pulled by the main wheel 2211 and the floating belt 211, it rotates inside the functional pier 143 and the guide pier 142. The end of the cleaning machine 221 near the main gate 321 is tilted upward to match the collection platform 224 on the upper part of the functional pier 143. The collection platform 224 is a pit-shaped structure. The water inlet end of the cleaning machine 221 and the floating height of the floating belt 211 change synchronously, which can transport the floating objects in the collection area I 222 and the collection area II 223 to the collection platform 224, thereby fully ensuring the cleaning effect under different water level conditions.

[0040] Furthermore, in one embodiment, the valve assembly 31 includes a first cleaning valve 311, a second cleaning valve 312, and a third cleaning valve 313 disposed on the guide pipe 243.

[0042] Further, in some optional embodiments, the silt flushing device 23 includes a first silt collection area 231, a first silt flushing hole 232, a second silt collection area 233, and a second silt flushing hole 234. The first silt collection area 231 is formed between the bottom of the guide pier 142 and the bottom of the energy storage pier 144 located on the side of the gate chamber I 11, and the second silt collection area 233 is formed between the bottom of the guide pier 142 and the bottom of the energy storage pier 144 located on the side of the gate chamber II 12.

The silt flushing gate I 322 is arranged in the first silt flushing hole 232, and the silt flushing gate II 323 is arranged in the second silt flushing hole 234.

[0043] See Figure 7As shown, in this embodiment, the silt flushing device 23 is located at the bottom of the functional pier 143. The silt flushing device 23 includes a first silt collection area 231, a first silt flushing hole 232, a second silt collection area 233, and a second silt flushing hole 234. The silt deposits at the bottom of the main gate 321 can be flushed away by the raising and lowering of the main gate 321. The main siltation area is the closed still water environment at the bottom of the functional chamber 13. The first silt collection area 231 is the area formed between the bottom of the river-side guide pier 142 and the energy storage pier 144. The first silt flushing hole 232 penetrates the functional pier 143 and connects the bottom water of the gate chamber I 11 and the functional chamber 13. The second silt collection area 233 is the area formed between the bottom of the seawater-side guide pier 142 and the energy storage pier 144. The second silt flushing hole 234 penetrates the functional pier 143 and connects the bottom water of the gate chamber II 12 and the functional chamber 13. The easily silted areas at the bottom of the gate chamber I 11, the gate chamber II 12, and the functional chamber 13 can be interconnected.

[0044] See Figure 7 As shown, the siltation gate I 322 is arranged in the groove of the first siltation hole 232 and can slide vertically along the groove. It opens the first siltation hole 232 to connect the water environment of the bottom first siltation area 231 of the gate chamber I 11 and the functional chamber 13, or closes the first siltation hole 232 to separate the water environment of the bottom first siltation area 231 of the gate chamber I 11 and the functional chamber 13. The siltation gate II 323 is arranged in the groove of the second siltation hole 234 and can slide vertically along the groove. It opens the second siltation hole 234 to connect the water environment of the bottom second siltation area 233 of the gate chamber II 12 and the functional chamber 13, or closes the second siltation hole 234 to separate the water environment of the bottom second siltation area 233 of the gate chamber II 12 and the functional chamber 13. The gate assembly 32 can be opened and closed by using a winch or hydraulic rod for lifting and lowering.

[0045] See Figure 3 and Figure 5As shown, the connecting device 24 is located on the top of the functional pier 143, connecting the gate chamber I 11, the gate chamber II 12, and the functional chamber 13. The connecting device 24 may also include a guide channel 241 and a baffle plate 242. The guide channel 241 is arranged on the top of the functional pier 143 and includes an arc-shaped groove and a straight groove. The arc-shaped groove matches the rotation path of the main rotor 2211 of the cleaning machine 221. The top of the straight groove is connected to the top of the arc-shaped groove and extends vertically to the top of the functional pier 143. The baffle plate 242 is arranged in the guide channel 241 and is flush with the outer wall of the functional pier 143. The baffle plate 242 slides up and down along the straight groove of the guide channel 241 and cannot be removed from the guide channel 241. In this embodiment, the guide pipe 243 is a hollow tube structure. The guide pipe 243 passes through the functional pier 143 and the guide channel 241 and connects to the main impeller 2211. The guide pipe 243 inside the functional pier 143 is a steel structure, and the guide pipe 243 inside the guide channel 241 is a flexible tube structure. The two ends of the guide pipe 243 away from the functional chamber 13 are respectively connected to the cleaning device 22 and the debris blocking device 21 of the gate chamber I 11 and the gate chamber II 12. The end of the guide pipe 243 near the functional chamber 13 extends into the functional chamber 13, forming a water conveying channel for the floating belt 211 of the gate chamber I 11, the main impeller 2211, the functional chamber 13, the main impeller 2211 of the gate chamber II 12, and the floating belt 211. Under the floating and pulling action of the floating belt 211, the cleaning machine 221 rotates around the driven shaft 2215, and the hose of the guide pipe 243 inside the guide channel 241 moves together. During this process, the baffle plate 242 can prevent floating objects in the collection area I 222 and the collection area II 223 from entering the guide channel 241. In addition, the hose design of the guide pipe 243 inside the guide channel 241 is also convenient for replacement and maintenance, thereby ensuring the continuity and reliability of the movement of the connecting device 24 during the dynamic water level process.

[0046] This application integrates the structural and functional features of traditional tidal gates with their horizontal and vertical opening and closing mechanisms, and introduces gate chamber cleaning and silt removal functions. This overcomes the common problems of floating debris pollution and siltation in tidal gates. Considering the tidal phenomena in the environment where the tidal gate is located, a hydraulic energy storage tidal gate system under gate valve linkage is constructed using gate chamber module 1, hydraulic transmission module 2, and control module 3. The tidal phenomena generate weak tidal ranges of less than 2 meters, medium tidal ranges of 2 to 4 meters, and strong tidal ranges of over 4 meters. These continuous and regularly changing tidal ranges contain abundant and stable hydraulic potential energy. The energy storage design of gate chamber module 1 can continuously collect this hydraulic potential energy, which is then connected to the debris-blocking device through the connecting device 24 of hydraulic transmission module 2. 21. The cleaning device 22 and the silt flushing device 23 form a hydraulic flow guiding loop. With the coordinated opening and closing of the valve group 31 and the gate group 32 of the control module 3, the functions of intercepting, cleaning, and silting are efficiently integrated, achieving stable and sustainable energy storage of tidal potential energy, adjustable transmission of hydraulic potential energy, and conversion of kinetic energy. First, the intercepting device 21 guides floating objects to the cleaning area; second, the cleaning device 22 cleans and collects floating objects; and third, the silt flushing device 23 solves the siltation problem in the energy storage chamber of the above-mentioned hydrodynamic source. The three functions are interlinked and complementary, forming a low-carbon, environmentally friendly, stable, and efficient hydraulic automatic intercepting, cleaning, and silt flushing function, providing a new technical approach for the development of tidal gates.

[0047] This application fully utilizes the tidal characteristics of the environment where the tide gate is located, links the structure of the tide gate system with the gate valve, and introduces devices such as the functional chamber 13 to cooperate with the relative rise and fall of the sea level 121 and the river level 111 under the tidal phenomenon. This realizes the combination of the structure and operation mode of the tide gate system with the hydraulic cleaning, water purification and dredging functions, so as to realize the continuous cleaning and dredging functions during the operation of the tide gate under different working conditions.

[0048] This application also provides a control method for a hydraulic energy storage tidal barrier system, which may include the following steps: S100: When the tide is high and cleaning is required, control the first cleaning valve 311, the second cleaning valve 312 and the third cleaning valve 313 to open and control the gate group 32 to close, so that the water in the gate chamber II 12 enters the functional chamber 13 and the gate chamber I 11 through the connecting device 24. At the same time, the debris blocking device 21 and the cleaning device 22 perform cleaning.

[0049] S200: When the tide recedes and cleaning is required, control the first cleaning valve 311 and the second cleaning valve 312 to open and control the gate assembly 32 to close, so that the water in the gate chamber I11 enters the gate chamber II12 through the connecting device 24, and at the same time the debris blocking device 21 and the cleaning device 22 perform cleaning.

[0050] The control method in this embodiment is applicable to the hydraulic energy storage tide gate system provided in any of the above embodiments and realizes the corresponding functions, which will not be described in detail here.

[0051] In this embodiment, when the river level 111 is significantly lower than the sea level 121 at high tide, the valve group 31 and the gate group 32 are in the closed state, and the control module 3 stores energy and performs the functions of cleaning and dredging.

[0052] In the above S100, when the gate chamber module 1 is cleaned, the first cleaning valve 311, the second cleaning valve 312, and the third cleaning valve 313 are opened. The sea level 121, the water storage surface 131, and the river level 111 form a flow guide loop through the connecting device 24. The lower layer of water at the sea level 121 enters the floating belt 211 through the inlet 212, flows through the main runner 2211, and enters the floating belt 211 at the river end. The downstream water flows into the river level 111 from the cleaning hole 213 at the river end. During this process, the functional chamber 13 stores energy until... The water level 131 gradually approaches the sea level 121. Under the guidance of the cleaning hole 213, the water inlet at the sea level 121 and the water outlet at the river level 111 push the floating objects at the sea level 121 and the river level 111 toward the collection area II 223 and the collection area I 222, respectively. The main blades 2213 inside the main rotor 2211 drive the cleaning machine 221 to drive the track 2217 to clean up the floating garbage gathered in the collection area II 223 and the collection area I 222, and then transport and stack it on the collection platform 224.

[0053] Preferably, the gate assembly 32 includes a siltation gate I 322 and a siltation gate II 323. The siltation gate I 322 is located at the connection between the functional chamber 13 and the gate chamber I 11, and the siltation gate II 323 is located at the connection between the functional chamber 13 and the gate chamber II 12. When the river level 111 is significantly lower than the sea level 121 at high tide and dredging is required, the siltation gate II 323 is opened and the valve assembly 31 is closed. The bottom of the gate chamber II 12 and the functional chamber 13 are connected. The sediment in the second silt collection area 233 is discharged into the functional chamber 13 through the second siltation hole 234 under the disturbance of the bottom water flow, and at the same time, the potential energy of the water inside the functional chamber 13 rises.

[0054] In step S200, when the river level 111 is significantly higher than the sea level 121 at low tide, the valve group 31 and the gate group 32 are in the closed state, and the control module 3 can perform the functions of cleaning and dredging.

[0055] In step S200 above, when the gate chamber module 1 is cleaned, the first cleaning valve 311 and the second cleaning valve 312 are opened. The river level 111 and the sea level 121 form a closed flow guide loop through the connecting device 24. The lower layer of water at the river level 111 enters the floating belt 211 through the inlet hole 212, flows through the main impeller 2211, and enters the floating belt 211 at the seawater end. The downstream water flows into the sea level 121 from the cleaning hole 213 at the seawater end. During this process, the functional chamber 13 does not participate. During operation, the water inlet at river level 111 and the water outlet at sea level 121, guided by the direction of the cleaning hole 213, push the floating debris at river level 111 and sea level 121 toward the collection area I 222 and collection area II 223, respectively. The main blades 2213 inside the main rotor 2211, driven by the water flow, drive the cleaning machine 221 to drive the track 2217 to clean up the floating garbage gathered in collection area I 222 and collection area II 223, and convey and stack it on the collection platform 224.

[0056] Furthermore, when the river level 111 is significantly higher than the sea level 121 at low tide and dredging is required, the dredging gate I 322 is opened and the valve group 31 is closed. The gate chamber I 11 and the bottom of the functional chamber 13 are connected. The sediment in the first sediment collection area 231 is discharged into the functional chamber 13 through the first dredging hole 232 under the disturbance of the bottom water flow.

[0057] Furthermore, in one embodiment, the above control method further includes step S300: when the water level 131 is significantly higher than the sea level 121 at low tide, the valve group 31 and the gate group 32 are in a closed state, and the control module 3 releases energy and implements water purification and dredging functions. Specifically: When the gate chamber module 1 releases energy, the second cleaning valve 312 and the third cleaning valve 313 are opened, and the water storage surface 131 and the sea level 121 form a closed flow guide circuit through the connecting device 24. The water in the middle layer of the water storage surface 131 enters the sea level 121 and continuously decreases, while the potential energy of the water inside the functional chamber 13 decreases.

[0058] The decrease in water potential energy inside functional chamber 13 creates favorable conditions for the water purification and dredging functions of gate chamber module 1. When the gate chamber module 1 is purifying and dredging water, valve group 31 is closed to isolate the internal environment of functional chamber 13. After the water is exposed to the sun and evaporates, the sediment and non-floating pollutants in the water gradually settle to form silt. Dry dredging is carried out manually or mechanically. The silt and non-floating pollutants in the river channel where the gate chamber module 1 is located are spatially replaced by functional chamber 13, and the conditions for water purification and dredging are met.

[0059] This process uses silt flushing gates I 322 and II 323 to discharge silt from the channels before and after the main gate 321 into the functional chamber 13. Firstly, it effectively avoids the risk of blockage and siltation in the bottom slot of the main gate 321 caused by traditional bottom-hole dredging. Secondly, the functional chamber 13 endows the gate chamber module 1 with diversified functions and provides water purification and dredging conditions, including transforming traditional underwater dredging into dry dredging within the functional chamber 13 by replacing the siltation space, effectively preventing river pollutants from entering the ocean.

[0060] The above control method may also include controlling the main gate 321 to rise and open or fall and close, so that the tide gate system can normally perform the functions of blocking water and draining water, and can synchronously operate the functions of energy storage, energy release, cleaning or dredging in conjunction with the operation of S100-S300.

[0061] This application incorporates the energy storage design of the gate chamber module 1, which combines tidal phenomena to store stable and reliable hydraulic potential energy as an ecological power source and functional replacement space for the traditional gate chamber during water blocking and drainage processes. Simultaneously, the hydraulic transmission module 2 utilizes the debris-blocking device 21 to guide floating debris to the cleaning area, the cleaning device 22 to clean and collect floating debris, and the silt-flushing device 23 to solve the siltation problem in the energy storage gate chamber, thus creating favorable conditions for traditional manual or mechanical silt removal and water purification during water exchange. Furthermore, the control module 3 adaptively adjusts the opening of the valve group 31 and the gate group 32 based on the combination of water levels at river level 111, sea level 121, and water storage surface 131, as well as the situation of floating debris and siltation. This achieves a synergistic and interconnected function of energy storage, energy release, debris removal, and silt removal under the coordinated operation of the tidal gate system structure and gate valves, fully leveraging the coupling benefits of the tidal gate system's engineering operation and ecological governance, and possessing broad development prospects and application value.
