The one-way partition plate 23 is located between the top of the inlet and outlet pipe 8 and the top of the flushing pipe 9, which can enable the water output from the inlet and outlet pipe 8 or the flushing pipe 9 to flow in one direction.

[0030] like Figure 3-6 As shown, a water tank 31 is installed in the backwash layer 3, and the top of the water tank 31 extends to the repair layer 2.

The output end of the electric push rod 1 41 is connected to the sealing plate 33, and the electric push rod 1 41 can control the lifting and lowering of the sealing plate 33 to seal the water inlet of the water tank 31. The output end of the electric push rod 2 42 is connected to the arc-shaped sealing plate 34, and the electric push rod 2 42 can control the lifting and lowering of the arc-shaped sealing plate 34 to seal the regulating chamber 35, so that the flushing pipe 9 is sealed and separated or connected with the water flow channel 36.

[0032] A water level sensor is installed in the water tank 31 to monitor the water level in the water tank 31 . The water level sensor is connected to the PLC controller 43 via a signal.

[0033] like Figure 8-9 As shown, a piston plate 51 is sealed and sleeved in the water storage layer 5, a water storage chamber is formed between the top of the piston plate 51 and the water storage layer 5, and a hydraulic cylinder 52 is installed in the water storage layer 5, the piston plate 51 is controlled by the hydraulic cylinder 52, and a sewage pipe 53 is vertically fixedly sleeved in the center of the driving control layer 4, the output end of the sewage pipe 53 passes through the piston plate 51 and extends to the collecting mesh groove 6 below the water storage layer 5, the collecting mesh groove 6 is connected to the restoration 1 through a locking assembly 7, and the collecting mesh groove 6 is a fine filter.

[0034] The aquifer 5 is connected to the repair layer 2 through the inlet and outlet pipes 8, and the repair layer 2 is connected to the backwash layer 3 through the flushing pipe 9. The top of the inlet and outlet pipes 8 is higher than the top of the flushing pipe 9, and the bottom of the flushing pipe 9 extends to the regulating chamber 35. The A port and C port of the three-way valve 44 are respectively connected to the inlet and outlet pipes 8. The inlet and outlet pipes 8, the A port and the C port of the three-way valve 44 are considered to be integrated, that is, the aquifer 5 is connected to the repair layer 2 through the inlet and outlet pipes 8, the C port and the A port, and the B port of the three-way valve 44 is connected to the input end of the sewage pipe 53 through a pipeline.

[0035] like Figure 1 As shown, the water inlet assembly includes a water inlet trough 10 and a driving water wheel 11. The water inlet trough 10 is arranged above the restoration 1, and a water supply channel 12 is opened on the water inlet trough 10. The driving water wheel 11 is installed at the input end of the water supply channel 12. The driving water wheel 11 is installed on the water inlet trough 10 through a wheel frame 14. The water wheel can be driven by a water wheel motor. The water wheel 11 can be driven to rotate by the water wheel motor or natural water flow to introduce water in the river channel into the water inlet trough 10. The side of the water inlet trough 10 is connected to a water inlet pipe 13. The input end of the water inlet pipe 13 is connected to the water storage chamber of the aquifer 5. When the piston plate 51 moves upward, its maximum stroke does not exceed the output end of the water inlet pipe 13, that is, the top of the piston plate 51 is lower than the output end of the water inlet pipe 13.

[0036] The buoyancy assembly includes a float 15 disposed on the outer peripheral side of the water inlet tank 10, which is used to provide buoyancy to the prosthesis 1 so that the prosthesis 1 floats in the water and adapts to changes in water level.

[0037] An anchoring assembly is provided, which includes an anchoring block 19 connected to the restoration 1 through a traction rope 18, and can anchor the restoration 1 and fix the restoration 1 in the river channel so that it can maintain a stable position in the water flow without drifting, thereby ensuring stability.

[0038] In order to ensure the sustainable operation of the device, a power supply component is also provided, which includes a solar panel installed on the side of the water inlet tank 10. The top of the centrifugal pump 32 extends out of the repair layer 2, and a battery 17 is provided on the top of the centrifugal pump to use solar energy to provide power to the system to ensure the continuous operation of the repair device.

[0039] At the same time, the collecting net slot 6 can be disassembled and replaced by the locking assembly 7. Fig.10 The lock assembly 7 comprises a locking block 71 installed at the bottom of the aquifer 5. A plurality of locking rods 72 are circumferentially mounted on the locking block 71. The inner end of the locking rod 72 is provided with an inclined surface. A pressure cylinder 77 is fixed on the outer peripheral side of the locking block 71. The outer end of the locking rod 72 is mounted in the pressure cylinder 77. A top spring 74 is connected between the pressure cylinder 77 and the outer end of the locking rod 72. A release rod 73 is also connected to the outer end of the locking rod 72. The release rod 73 extends out of the pressure cylinder 77 and is fixedly connected to a cartridge 75 at the top of the collecting net slot 6. The cartridge 75 is communicated with the inside of the collecting net slot 6. The output end of the sewage pipe 53 can be matched and mounted in the cartridge 75 to communicate with the collecting net slot 6. A cartridge slot 76 is circumferentially opened on the outer peripheral side of the cartridge 75. The inner end of the locking rod 72 can be sleeved in the cartridge slot 76 to lock the collecting net slot 6. Pulling the release rod 73 can release the constraint lock of the locking rod 72 on the cartridge 75, thereby replacing the collecting net slot 6. Based on the principle of Hero's Fountain, this device uses air pressure, water weight, and the water level difference between the inlet and outlet water. Based on the interaction between air pressure and water flow, the pressure difference is used to drive the water flow to achieve a self-circulating process of water purification.

[0040] The device has two working states: water self-circulation purification and backwashing self-cleaning.

[0041] Self-circulating water purification: drive the water wheel 11 to rotate and transport the water in the river channel to the water inlet pipe 13 through the water inlet trough 10 and the water delivery channel 12. The water inlet pipe 13 transports water to the aquifer 5. When the water storage cavity in the aquifer 5 is full of water and there is no air, the hydraulic cylinder 52 drives the piston plate 51. When the piston plate 51 pushes water from the aquifer 5 to the repair layer 2, the water in the aquifer 5 enters the repair layer 2 through the inlet and outlet pipes 8. Under the action of the one-way partition 23, the water in the repair layer 2 passes through the grid nets 22 of large, medium and small apertures in turn in one direction, and can intercept pollutants of different particle sizes in the water through the large, medium and small grid nets; Then the water entering the repair layer 2 will enter the backwash layer 3 unidirectionally through the flushing pipe 9, and at the same time, the air in the backwash layer 3 will be pressed into the repair layer 2. When the water fills the backwash layer 3, the water in the backwash layer 3 will overflow to the repair layer 2 through the flushing pipe 9 again, and the repair layer 2 will be gradually filled with water. At this time, there is water and air in the repair layer 2, and the water body is bioremediated by the microbial remediation agent in the repair layer 2. At the same time, because the top of the inlet and outlet pipe 8 is higher, there is water only in the repair layer 2 and the backwash layer 3 at this time, and the water in the repair layer and the backwash layer is in an independent state. Then the hydraulic cylinder 52 controls the piston plate 51 to move downward and reset, and the water inlet pipe 13 transports river water to the aquifer 5, and the aquifer 5 is filled with water again. It should be noted that when the piston plate 51 moves upward to push the water in the water storage cavity of the aquifer 5 to enter the repair layer 2, the maximum stroke of the piston plate 51 does not exceed the output port of the water inlet pipe 13, that is, the top of the piston plate 51 is lower than the output port of the water inlet pipe 13; and only when the water storage cavity in the aquifer 5 is full of water and there is no air, the hydraulic cylinder 52 will drive the piston plate 51 to move upward; The annular cavity between the water storage tank 31 and the backwashing layer 3 forms a water flow channel 36, and the water flow channel 36 is connected to the water outlet pipe 16; When the piston plate 51 moves upward, the water in the water storage layer 5 is transported to the repair layer 2. In the initial state, the plugging plate 33 is closed and the arc plugging plate 34 is opened. At this time, the flushing pipe 9 is connected to the water flow channel 36. The water in the repair layer 2 enters the backwashing layer 3 through the flushing pipe 9, and the water in the backwashing layer 3 is in the water flow channel 36. It can also be understood that when the plugging plate 33 is closed and the arc plugging plate 34 is opened, the water in the repair layer 2 can enter the backwashing layer 3 through the flushing pipe 9, and the water is temporarily stored in the water flow channel 36. When the water wheel 11 is driven to continue to deliver water, so that the water level of the water inlet tank 10 exceeds the input end of the water inlet pipe 13, a pressure difference will be formed between the inner chamber of the repair layer 2 and the outside. Under the action of air pressure, the water of the backwash layer 3 will be pressed out through the outlet pipe 16 and discharged into the river, thus realizing the in-and-out circulation of the water body; When the piston plate 51 moves upward to transport the water from the aquifer 3 to the repair layer 2, when the water level sensor detects that the water in the water tank 31 is insufficient and needs to be replenished, the arc-shaped sealing plate 34 is closed and the sealing plate 33 is opened. The arc-shaped sealing plate 34 separates the flushing pipe 9 and the water flow channel 36. At this time, the flushing pipe 9 and the water flow channel 36 are in a blocked state, and the flushing pipe 9 and the water tank 31 are in a connected state. When the water from the repair layer 2 enters the backwashing layer 3 through the flushing pipe 9, since the arc-shaped sealing plate 34 is closed and the sealing plate 33 is opened, the water will flow directly into the water tank 31 to store water in the water tank 31. When the water level sensor detects that the water in the water tank 31 reaches the water level line, the sealing plate 33 is closed and the arc-shaped sealing plate 34 is opened. At this time, the water flows into the water flow channel of the backwashing layer 36 and can be discharged into the river through the outlet pipe 16.

[0042] Backwashing self-cleaning process: A three-way valve 44 is installed in the driving control layer 4, and the A port 441 and the C port 443 of the three-way valve 44 are respectively connected to the inlet and outlet pipes 8, and the B port 442 of the three-way valve 44 is connected to the sewage pipe 53 through a pipeline; The three-way valve is a prior art, and the circuit switching between the B port and the C port of the three-way valve can be realized through the PLC controller 43; When port C of the three-way valve is opened and port B is closed, water from the aquifer can enter the repair layer through the inlet and outlet pipe 8, port C and port A; When the port B of the three-way valve is opened and the port C is closed, the water in the repair layer 2 can enter the sewage pipe 53 through the inlet and outlet pipe 8, the port A and the port B; When backwashing is required, the arc-shaped sealing plate 34 is closed, the sealing plate 33 is opened, the B port of the three-way valve is opened, the C port is closed, and the centrifugal pump 32 is started, so that the water in the water storage tank 31 enters the repair layer 2 through the flushing pipe 9 for backwashing. Under the action of the one-way partition 23, the water entering the repair layer 2 passes through the small, medium and large grids in turn in one direction, which can flush the pollutants blocked in the small, medium and large grids, and then enter the inlet and outlet pipe 8. At this time, the dirt will enter the drain pipe 53 through the inlet and outlet pipe 8, the A port and the B port, and be discharged into the collection network slot 6, realizing the backwashing self-cleaning of the repair body.

[0043] The progressive river ecological restoration device of this embodiment realizes efficient purification of water through a multi-layer structural design combined with physical and biological means. At the same time, the addition of power components enables the device to be self-powered, enhancing environmental adaptability, and the intelligent control and automatic backwashing functions reduce maintenance costs.

[0044] Example 2, a self-cleaning water purification and ecological restoration device in this embodiment is described with the differences from Example 1 as the center.

[0045] In this embodiment, a constant temperature heating belt can also be installed on the inner ring wall of the repair layer 2, and a temperature sensor can be installed in the microbial repair layer. The ambient temperature of the microbial repair layer is monitored by the temperature sensor, and the PLC controller controls the heating of the constant temperature heating belt. Through the heating of the constant temperature heating belt, the ambient temperature of the microbial repair layer is adjusted to stimulate the activity of microorganisms and improve the water purification and repair effect.

[0046] Example 3, a self-cleaning water purification and ecological restoration device in this embodiment is described with the differences from Example 1 as the center.

[0047] In this embodiment, a debris blocking net is installed in the water inlet trough 10 for blocking impurities. The debris blocking net is higher than the input end of the water inlet pipe 13. The debris blocking net in the water inlet trough 10 can intercept impurities in the water body and perform primary filtration on the water body. The debris blocking net in the water inlet trough 10 will intercept larger impurities, protect the internal components of the device from damage, and ensure the initial purification of the water body.
