DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Example 1

[0040] Reference Figure 1-Figure 7 A purification device, comprising: a plurality of installation grooves 2 are provided at appropriate positions of a river channel 1, and the depth and width of the installation grooves 2 need to be designed according to the size of a purification box 3 to ensure that the purification box 3 can be firmly installed therein. The purification box 3 is made of corrosion-resistant material, and its interior is divided into a water inlet chamber 11 and a purification chamber 31. The water inlet chamber 11 is directly connected to the river channel 1 and receives water from the river channel through a water inlet hole 43. The width of the river channel 1 in the attached figure is only a schematic representation, not the actual width.

[0041] A guide tube 7 is fixedly arranged in the purification chamber 31, and a through hole 28 is formed at the bottom of the guide tube 7. A planting tray 6 is slidably sleeved on the outer wall of the guide tube 7, and a plurality of planting grooves 29 are formed on the planting tray 6 for planting aquatic plants such as reeds, water celery, etc. These aquatic plants absorb nutrients and heavy metals in the water through their roots, and release oxygen at the same time, promoting the activity of aerobic microorganisms in the water body, thereby effectively purifying the water quality.

[0042] A plurality of water pumps 4 are arranged on the side of the river channel 1, and each water pump 4 corresponds to a purification box 3. The water inlet end of the water pump 4 is connected to the top of the guide pipe 7 through the water inlet pipe 8, and is used to pump out the water in the upper layer of the purification chamber 31 that has been preliminarily purified. The drainage end of the water pump 4 is fixedly connected to a drainage pipe 5, and the other end of the drainage pipe 5 is fixed in the river channel 1, forming a circulating water flow, and the purified water is discharged back to the river channel, so as to achieve continuous improvement of water quality.

[0043] On one side of the purification box 3, a blocking plate 35 is slidably provided. The blocking plate 35 is used in conjunction with the planting tray 6. When the water level in the purification chamber 31 rises to a certain height, the planting tray 6 floats up, pushing the blocking plate 35 to slide and seal the water inlet 43, preventing more water from entering the purification chamber 31. When the water level in the purification chamber 31 drops, the planting tray 6 drops accordingly, and the blocking plate 35 automatically opens the water inlet 43 under the action of gravity, allowing new water to flow in.

[0044] On one side of the purification box 3, a guide mechanism is provided to guide the garbage in the river into the purification box 3. The guide mechanism includes a connection seat 38 fixedly provided on one side of the purification box 3, and a guide plate 10 is rotatably provided in the connection seat 38. The guide plate 10 is elastically supported by a support member including a second rotating seat 42, a sleeve rod 41, a rotating rod 40, a first rotating seat 39 and a spring, and its direction is opposite to the direction of the water flow. When the water flow carries the garbage through, the guide plate 10 will guide the garbage into the purification box 3 to achieve preliminary purification of the river.

[0045] A filtering mechanism, such as a filter screen or a grille, is provided on the water inlet chamber 11 to intercept and remove large particles of garbage and suspended solids in the water. These filtering mechanisms can effectively reduce the pollutant load entering the purification chamber 31 and improve the processing efficiency and stability of the entire purification system.

[0046] The filter mechanism mainly includes a sliding frame 16 and two filter plates 17. The sliding frame 16 is designed to slide along a specific track of the water inlet chamber 11 for replacement or maintenance operations. The two filter plates 17 are respectively located in the sliding frame 16, and one of the filter plates 17 is located just above the water inlet chamber 11 to intercept and filter garbage and suspended matter in the incoming water.

[0047] In order to realize the automatic replacement of the filter plate 17, two mounting seats 18 are fixedly installed on one side of the water inlet chamber 11, and an electric push rod 19 is fixedly installed between the two mounting seats 18. Three baffles 20 are fixedly provided on the top of the sliding frame 16, and the filter plate 17 is located between two adjacent baffles 20. The output end of the electric push rod 19 is fixedly connected to one of the baffles 20. Through the telescopic movement of the electric push rod 19, the entire sliding frame 16 and the filter plate 17 inside can be driven to move horizontally, thereby realizing the replacement of the filter plate 17.

[0048] In order to prevent the sliding frame 16 and the mounting seat 18 from getting stuck during the movement, two baffles 20 located on the action side of the electric push rod 19 are provided with rectangular openings 21 corresponding to the mounting seat 18, so that the movement can be smooth and unobstructed even during the movement.

[0049] In order to further improve the automation degree and garbage processing efficiency of the device, two collection chambers 12 are designed in the purification box 3, which are respectively located on both sides of the water inlet chamber 11. The filter plate 17 is designed to be rotatable. When the sliding frame 16 drives the filter plate 17 to move above the collection chamber 12, the filter plate 17 will automatically flip over and pour the garbage trapped on it into the corresponding collection chamber 12, thereby realizing automatic collection and classification of garbage.

[0050] In order to assist in the efficient collection and discharge of garbage, a chute 22 is further provided on one side of the collection chamber 12, and a pulley 26 is installed in the chute 22. At the same time, a sliding block 25 is slidably provided in the chute 22, and a lifting plate 14 is fixedly connected to one side of the sliding block 25. Two mounting holes 24 are provided on the top of the lifting plate 14, and guide rods 13 are slidably provided in the two mounting holes 24, respectively, and the bottom end of the guide rod 13 is fixedly connected to the bottom wall of the collection chamber 12.

[0051] In addition, a pull rope 27 is fixedly connected to the top of the sliding block 25, and the other end of the pull rope 27 passes through the pulley 26 and is fixedly connected to the corresponding baffle 20 on the sliding frame 16. When the electric push rod 19 drives the baffle 20 and the sliding frame 16 to move, the pull rope 27 on the other side will be pulled accordingly, thereby driving the sliding block 25 and the lifting plate 14 to rise along the guide rod 13. In this way, when the filter plate 17 flips over to pour the garbage into the collection chamber 12, the lifting plate 14 on the other side will also push the garbage at the bottom of the collection chamber 12 upward, which is convenient for subsequent cleaning and discharge.

[0052] At the same time, in order to ensure that the filter plate 17 does not conflict with the guide rods 13 during the flipping and moving process, a clearance hole 23 corresponding to the two guide rods 13 is also opened on the top of the filter plate 17 to ensure the smooth progress of the entire operation process.

[0053] The present application can be used in the field of water treatment, and can also be used in other fields applicable to the present application.

[0054] Example 2

[0055] refer to Figure 1-Figure 7 , improved on the basis of Example 1: A multi-stage water ecological purification device for a river, which is applied to the field of water quality treatment, in order to realize that the planting tray 6 can automatically drive the blocking plate 35 to move up and down during the lifting process, in this embodiment, two extension frames 9 are fixedly provided on the top of the planting tray 6. The two extension frames 9 are respectively located on both sides of the planting tray 6, and the inner sides thereof are fixedly provided with a first limit block 36 and a second limit block 37. The first limit block 36 and the second limit block 37 form a certain interval in the vertical direction to accommodate and guide the sliding of the blocking plate 35.

[0056] At the corresponding position of the purification box 3, the blocking plate 35 is designed to be located between the first limit block 36 and the second limit block 37. When the planting tray 6 rises and falls with the change of water level, the first limit block 36 and the second limit block 37 on the extension frame 9 will move up and down accordingly, and through the resistance force with the blocking plate 35, the blocking plate 35 is driven to move up and down accordingly. In this way, when the water level in the purification chamber 31 rises, the planting tray 6 rises, driving the blocking plate 35 to move up, gradually closing the water inlet 43; conversely, when the water level drops, the planting tray 6 drops, driving the blocking plate 35 to move down, and opening the water inlet 43.

[0057] In order to ensure that the blocking plate 35 can be stably maintained at a certain position after the driving force of the planting tray 6 is lost, and can be automatically reset when needed, in this embodiment, a fixing plate 32 is fixedly provided on one side of the purification box 3. Two fixing rods 33 are fixedly provided on the top of the fixing plate 32, and the blocking plate 35 is designed to be slidably sleeved on the two fixing rods 33 to achieve stable sliding guidance.

[0058] A spring 34 is sleeved on the outer wall of the fixing rod 33, and the two ends of the spring 34 are respectively fixedly connected to the blocking plate 35 and the side of the fixing plate 32 close to each other. In this way, when the blocking plate 35 is moved by an external force such as the planting tray 6, the spring 34 will be compressed; when the external force disappears, the elastic force of the spring 34 will automatically reset the blocking plate 35 to the initial position.

[0059] In particular, in order to achieve an incomplete sealing effect, the reset force of the spring 34 is designed to maintain a certain gap with the water inlet 43 after the sealing plate 35 is reset, thereby allowing a small amount of water to flow through to maintain the water fluidity and ecological balance in the purification chamber 31.

[0060] In order to ensure the stable movement of the planting tray 6 in the purification chamber 31 and prevent it from excessively shaking or moving away from the preset position due to water flow fluctuations, in this embodiment, a limit frame 30 for limiting the planting tray 6 is fixedly provided in the purification chamber 31.

[0061] The shape and size of the limit frame 30 match the planting tray 6 to further limit the lifting stroke of the planting tray 6 to prevent it from exceeding a preset range.

[0062] A method for using a multi-stage river water ecological purification device comprises the following steps:

[0063] S1. First, install the device in the installation groove 2 on the river channel 1, and fix the end of the drainage pipe 5 away from the water pump 4 in the river channel 1;

[0064] S2, the water will flow into the water inlet cavity 11 through the water inlet hole 43 and the filter plate 17 during the flow, and the garbage will fall onto the filter plate 17 through the guide plate 10 and the water inlet hole 43 during the flow;

[0065] S3, the filtered water in the water inlet chamber 11 flows into the purification chamber 31 through the drainage hole 15, and can drive the planting tray 6 to move upward through the buoyancy of the planting tray 6. After the planting tray 6 moves upward into place, it can drive the blocking plate 35 to seal the water inlet hole 43, stop water inflow, and purify the water through the water plants planted in the planting groove 29;

[0066] S4, after the purification is completed, the water pump 4 is started to pump the water in the purification chamber 31 into the river channel 1 for circulation purification treatment;

[0067] S5. During the process of extracting water from the purification chamber 31, the planting tray 6 can move downward under gravity and drive the blocking plate 35 to move downward, and continue the water intake action.

[0068] In the present application, first, the device is installed in the installation groove 2 on the river channel 1, and the end of the drainage pipe 5 away from the water pump 4 is fixed in the river channel 1;

[0069] During the flow of water, the water will flow into the water inlet cavity 11 through the water inlet hole 43 and the filter plate 17. During the flow, the garbage will be guided by the guide plate 10 to move into the water inlet hole 43 and fall on the filter plate 17 for collection.

[0070] The filtered water in the water inlet chamber 11 flows into the purification chamber 31 through the drainage hole 15, and can drive the planting tray 6 to move upward through the buoyancy of the planting tray 6. During the upward movement of the planting tray 6, the extension frame 9 can be driven to move upward. The upward movement of the extension frame 9 can drive the blocking plate 35 to move upward through the second limit block 37 below. The upward movement of the blocking plate 35 can seal the water inlet hole 43, stop water inflow, and purify the water through the water plants planted in the planting groove 29;

[0071] After the purification is completed, the water pump 4 is started to pump the water in the purification chamber 31 into the river channel 1 for circulation purification treatment;

[0072] During the process of extracting water from the purification chamber 31, the planting tray 6 can move downward under gravity, and the downward movement of the planting tray 6 can drive the extension frame 9 to move downward. The downward movement of the extension frame 9 can drive the first limit block 36 to move downward, and can drive the blocking plate 35 to move downward, so that the blocking plate 35 moves to the bottom of the water inlet hole 43, and at this time, water can continue to enter the water inlet chamber 11;

[0073] When there is a lot of garbage on the filter plate 17, the electric push rod 19 is started to extend. The electric push rod 19 extends to enable the sliding frame 16 to move. The movement of the sliding frame 16 can drive the filter plate 17 to move to the left. When the filter plate 17 on the left does not contact the water inlet chamber 11, it will rotate downward under the action of gravity and pour the garbage into the collection chamber 12 on the left, and the right filter plate 17 moves to the left onto the water inlet chamber 11. During the movement, the filter plate 17 will be driven to flip upward through the water inlet chamber 11. At this time, the filter plate 17 is parallel to the sliding frame 16, and when the sliding frame 16 moves to the left, it will drive the pull rope 27 on the right to move. The movement of the pull rope 27 can drive the sliding block 25 to move upward. The upward movement of the sliding block 25 can drive the right lifting plate 14 to move upward, and the garbage on the right lifting plate 14 can be taken out. The lifting plate 14 on the left can move downward under the action of gravity, and the pull rope 27 on the left is tightened, and the garbage on the left and right lifting plates 14 is taken out in turn, and the lifted garbage can be cleaned manually.

[0074] However, as is well known to those skilled in the art, the working principles and wiring methods of the water pump 4 and the electric push rod 19 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
