Description

Technical Field

[0001] This invention relates to the field of wetland restoration technology, and in particular to a water purification system for natural wetland ecological restoration. Background Technology

[0002] Natural ecological wetlands refer to wetland ecosystems that are naturally formed, have been in a natural state for a long time, and have unique ecological functions and ecological value. The water quality of natural wetlands needs to be purified through purification devices to ensure the cleanliness of the wetland water.

[0003] A search revealed that Chinese patent CN221971378U discloses a wetland water quality ecological purification system, including a fixed plate. The upper end of the fixed plate is equipped with a purification mechanism for purifying water. The purification mechanism includes a functional chamber, a packing layer, and grooves. The functional chamber is fixedly mounted on the upper end of the fixed plate, and the packing layer is arranged inside the functional chamber. Several grooves are evenly arranged on the surface of the packing layer. The lower end of the fixed plate is equipped with a buoyancy mechanism to provide buoyancy for the device. The buoyancy mechanism includes a fixed frame and a buoyancy cavity. The fixed frame is fixedly mounted on the lower end of the fixed plate, and the buoyancy cavity is fixedly mounted inside the fixed frame. This solution allows the entire device to float on the wetland, thus filtering the wetland water and using aquatic plants to absorb and consume nitrogen and phosphorus in the water to prevent eutrophication. Furthermore, its ease of construction facilitates widespread use. However, the above solution still has the following shortcomings in practical use:

[0004] While the water purification devices proposed in the above scheme can prevent eutrophication, they cannot remove floating oil on the water surface. The main reasons for oily floating debris on the surface of natural wetlands include industrial emissions, algal reproduction and death, excessive organic matter, and natural factors. This oily floating debris has many disadvantages on the wetland ecosystem. The oil film on the water surface will block sunlight, affect the photosynthesis of algae, reduce oxygen production by zooplankton, and block gas exchange between the air and water, leading to water quality deterioration and reduced dissolved oxygen. It is usually accompanied by water quality indicators exceeding the standard and poor bottom sediment. Aquatic animals living in such an environment for a long time will have reduced resistance to disease and will be more susceptible to illness. In addition, oily floating debris will also emit odors to the surrounding area, and the need to improve the appearance of the water body cannot be met, which seriously affects the effect of water ecological management.

[0005] Therefore, it is necessary to design a natural wetland ecological restoration and water purification system to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a natural wetland ecological restoration water purification system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

One end of the pull rod is fixedly connected to the limiting plate, which slides in the slot. The sliding plate is arranged on the top surface of the pressure plate, and the limiting bracket is fixed to the top surface of the pressure plate. The sliding plate is slidably disposed in the limiting bracket, and an opening is provided on the sliding plate. A connecting rod is fixed on the pull rod, and a magnetic block is fixed to the end of the connecting rod away from the pull rod. A magnetic plate is fixed to the side of the sliding plate, and the magnetic block and the magnetic plate attract each other.

[0016] As a preferred embodiment of the present invention, the delivery assembly further includes a vertical rod, an end cap, a sliding sleeve, an opening, a partition, and an airbag. The vertical rod is fixed to the bottom surface of the float, the end cap is fixed to the end of the vertical rod away from the float, the sliding sleeve is slidably fitted onto the vertical rod and connected to the lifting tank, the opening is opened on the lifting tank, the partition is slidably disposed inside the lifting tank, one end of the airbag is connected to the partition, and the other end is connected to the inner surface of the lifting tank.

[0017] In a preferred embodiment of the present invention, the partition is arranged in the middle of the lifting tank, and the opening is located below the partition.

[0018] As a preferred embodiment of the present invention, the air supply assembly includes an installation cylinder, a threaded rod, a movable plate, a propeller blade, and an annular bladder. The installation cylinder is fixed to the side of the float by a bracket and is arranged vertically. The threaded rod is rotatably installed inside the installation cylinder, and the end of the threaded rod extends to the outside of the installation cylinder and is connected to the propeller blade. The movable plate is threaded onto the threaded rod. A limiting opening is formed on the outer circumferential surface of the installation cylinder, and a limiting block is fixed on the outer circumferential surface of the movable plate. The limiting ring slides in the limiting opening. One end of the annular bladder is connected to the inner surface of the installation cylinder, and the other end is connected to the movable plate. An air supply pipe is connected to the annular bladder, and the end of the air supply pipe away from the annular bladder is connected to the air bladder.

[0019] As a preferred embodiment of the present invention, the mounting cylinder, the threaded rod, and the movable plate are arranged coaxially.

[0020] In a preferred embodiment of the present invention, the threaded rod passes through the middle of the annular bladder, and the threaded rod and the annular bladder do not contact each other.

[0021] As a preferred embodiment of the present invention, the bottom surface of the sliding plate and the top surface of the pressure plate are in contact with each other, and the sliding plate is made of rubber material.

[0022] As a preferred embodiment of the present invention, the outer peripheral surface of the partition plate is in contact with the inner surface of the lifting tank.

[0023] The present invention has the following beneficial effects:

[0024] 1. This invention enables the automatic addition and uniform distribution of oil film remover in the surface water of a water body. The operator only needs to put the oil film remover into the storage tank, and then release the oil film remover by pulling the lever. The underwater driver drives the float to move, which in turn moves the lifting tank on the water surface, so that the oil film remover can be evenly sprayed into the surface water of the water body as the lifting tank moves, thereby effectively eliminating the oil film on the water surface and improving work efficiency and purification effect.

[0025] 2. The present invention also includes an air supply component. The movement of the float plate drives the propeller blades to rotate, which in turn drives the threaded rod to rotate, causing the moving plate to move up and down inside the mounting cylinder, squeezing or stretching the annular bladder. The amount of gas in the bladder is adjusted through the air supply pipe, thereby changing the buoyancy of the lifting tank in the water, causing it to move up and down continuously in the surface water. This design allows the spray nozzle to spray the oil film remover more evenly into the surface water, increasing the contact area and reaction time between the oil film remover and the oil film, thereby improving the oil film removal effect.

[0026] 3. The lifting action of the lifting tank does not require an additional power source. It is driven directly by the rotation of the propeller blades in the water when the float moves. Since the rotation of the propeller blades is driven by the water resistance naturally generated when the float moves, no additional electricity or fuel supply is required. This not only simplifies the system structure, reduces the complexity and manufacturing cost of the equipment, but also reduces energy consumption. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figures 1-9 A natural wetland ecological restoration water purification system includes a float 11, an underwater actuator 12 installed on the float 11 for driving the float 11 to move in the water, a through hole 13 on the float 11, a storage tank 21 on the top surface of the float 11 for storing oil film removal agent, a connecting pipe 22 connected to the side of the storage tank 21 and passing through the through hole 13, the top surface of the storage tank 21 is an open structure, four guide rods 23 are fixed inside the storage tank 21, the four guide rods 23 provide guidance for the movement of the pressure plate 31, and an insertion port 24 is opened at the top of the side of the storage tank 21.

[0039] The storage box 21 is equipped with a pressing component for pressing the oil film removal agent out of the storage box 21. The pressing component includes a pressure plate 31 and a counterweight 33. The pressure plate 31 is slidably disposed in the storage box 21, and the side of the pressure plate 31 is in contact with the inner surface of the storage box 21. Guide openings 32 are provided at the four corners of the pressure plate 31, and four guide rods 23 pass through the four guide openings 32. The counterweight 33 is fixed on the top surface of the pressure plate 31, and the pressure plate 31 is provided with an installation opening 34.

[0040] When using the natural wetland ecological restoration water purification system proposed in this invention, the staff first puts the oil film remover into the storage tank 21. In the initial state, the opening 45 on the sliding plate 44 is aligned with the mounting opening 34 on the pressure plate 31. The staff can inject the oil film remover into the storage tank 21 through the overlapping mounting opening 34 and opening 45. In addition, the limiting plate 43 is inserted into the insertion port 24 and extends into the storage tank 21. The pressure plate 31 rests on the limiting plate 43. At this time, the pressure plate 31 is located at the top of the storage tank 21. After adding the oil film remover, the staff places the floating plate 11 in the water area of ​​the ecological wetland.

[0041] A control assembly is provided on the side of the storage box 21 to control the pressing assembly. The control assembly includes a mounting frame 41, a pull rod 42, a limiting plate 43, a sliding plate 44, and a limiting bracket 46. The mounting frame 41 is fixed to the side of the storage box 21 and has an L-shaped structure. The pull rod 42 passes through the mounting frame 41 and is slidably connected to it. One end of the pull rod 42 is fixedly connected to the limiting plate 43, which slides in the slot 24. The sliding plate 44 is arranged on the pressure plate. The top surface of the sliding plate 44 and the bottom surface of the pressure plate 31 are in contact with each other, and the sliding plate 44 is made of rubber material. The limiting frame 46 is fixed on the top surface of the pressure plate 31, and the sliding plate 44 is slidably arranged in the limiting frame 46. The sliding plate 44 has an opening 45. A connecting rod 47 is fixed on the pull rod 42. A magnetic block 48 is fixed at the end of the connecting rod 47 away from the pull rod 42. A magnetic plate 49 is fixed on the side of the sliding plate 44. The magnetic block 48 and the magnetic plate 49 attract each other.

[0042] The bottom surface of the float 11 is provided with a dispensing assembly for dispensing oil film removal agent into the water. The dispensing assembly includes a lifting tank 54, which is connected to the end of the connecting pipe 22 away from the storage tank 21. The dispensing assembly also includes a vertical rod 51, an end cap 52, a sliding sleeve 53, an opening 55, a partition 56, and an airbag 57. The vertical rod 51 is fixed to the bottom surface of the float 11, the end cap 52 is fixed to the end of the vertical rod 51 away from the float 11, the sliding sleeve 53 is provided on the vertical rod 51 and is connected to the lifting tank 54, the opening 55 is opened on the lifting tank 54, the partition 56 is slidably disposed inside the lifting tank 54, and the outer peripheral surface of the partition 56 is in contact with the inner surface of the lifting tank 54. One end of the airbag 57 is connected to the partition 56, and the other end is connected to the inner surface of the lifting tank 54. The partition 56 is arranged in the middle of the lifting tank 54, and the opening 55 is located below the partition 56.

[0043] After the float 11 is placed, the worker pulls the handle on the pull rod 42, causing the pull rod 42 to move. As the pull rod 42 moves, it moves the limiting plate 43. Simultaneously, the pull rod 42 also moves the connecting rod 47, which in turn moves the sliding plate 44 until the opening 45 on the sliding plate 44 is completely misaligned with the mounting opening 34. At this point, the sliding plate 44 will block the mounting opening 34. Once the sliding plate 44 completely blocks the mounting opening 34, the worker continues to pull the pull rod. 42, make the pull rod 42 continue to move until the limit plate 43 is completely moved out of the storage box 21. Without the restriction of the limit plate 43, the pressure plate 31 can move downward inside the storage box 21 under the gravity of the counterweight 33. When the pressure plate 31 moves downward, the pressure plate 31 can press down the oil film removal agent in the storage box 21. The oil film removal agent will be pressed into the interior of the lifting tank 54 through the connecting pipe 22, and finally flow into the water through the opening 55, realizing the automatic addition of the oil film removal agent.

[0044] After the staff pulled lever 42, they then activated the underwater actuator 12, referring to... Figure 1 As shown, the underwater actuator 12 is used to drive the float 11 to move on the water surface. The specific structure and working principle of the underwater actuator 12 are existing technologies, and the implementation method adopts conventional means, which will not be elaborated here. The float 11 will move on the water surface under the action of the underwater actuator 12, and the lifting tank 54 will also move accordingly. In summary, during the movement of the lifting tank 54 in the water, the opening 55 simultaneously sprays the oil film removal agent, which allows the oil film removal agent to be evenly distributed in the surface water of the water body, thereby eliminating the oil film floating on the water surface. The specific principle of the oil film removal agent in eliminating the oil film is existing technology and will not be elaborated here.

[0045] As the pressure plate 31 descends, the sliding plate 44 on it also descends. The sliding plate 44 and the connecting rod 47 are connected by a magnetic block 48 and a magnetic plate 49 that attract each other. When the pressure plate 31 moves down, the magnetic block 48 will separate from the magnetic plate 49. This design makes it easy for the sliding plate 44 to move downward with the pressure plate 31, so that the sliding plate 44 and the connecting rod 47 can be freely separated. In addition, during the movement of the sliding plate 44, the limiting plate 43 provides a limit to ensure the stability of the movement of the sliding plate 44. Furthermore, the bottom surface of the sliding plate 44 and the top surface of the pressure plate 31 are in close contact with each other, and the sliding plate 44 is made of rubber material. This design can ensure the shielding effect of the sliding plate 44 on the mounting port 34.

[0046] An air supply assembly is provided on the side of the float 11. This assembly controls the vertical movement of the lifting tank 54. The air supply assembly includes an installation cylinder 61, a threaded rod 62, a movable plate 63, a propeller blade 66, and an annular bladder 67. The installation cylinder 61 is fixed to the side of the float 11 by a bracket and is vertically oriented. The threaded rod 62 is rotatably installed inside the installation cylinder 61, with its end extending to the outside of the cylinder and connecting to the propeller blade 66. The movable plate 63 is threadedly fitted onto the threaded rod 62. A limiting port 65 is opened on the outer peripheral surface of the movable plate 63. A limiting block 64 is fixed on the outer peripheral surface of the movable plate 63. The limiting ring slides in the limiting port 65. One end of the annular bladder 67 is connected to the inner surface of the mounting cylinder 61, and the other end is connected to the movable plate 63. The threaded rod 62 passes through the middle position of the annular bladder 67, and the threaded rod 62 and the annular bladder 67 do not contact each other. An air supply pipe 68 is connected to the annular bladder 67. The end of the air supply pipe 68 away from the annular bladder 67 is connected to the airbag 57. The mounting cylinder 61, the threaded rod 62 and the movable plate 63 are arranged coaxially.

[0047] To ensure the uniform distribution of the oil film remover in the surface water, this invention also includes an air supply component to drive the lifting tank 54 to move up and down in the surface water, thereby improving the oil film removal effect of the oil film remover. Specifically, as the float 11 moves, the mounting cylinder 61 moves accordingly, and the propeller blade 66 below the mounting cylinder 61 is submerged in the water. Therefore, the propeller blade 66 can rotate under the action of water resistance during its movement in the water, driving the threaded rod 62 to rotate. Under the restriction of the limiting port 65 and the limiting block 64, the moving plate 63 cannot follow the rotation of the threaded rod 62. Therefore, the moving plate 63 will move up and down inside the mounting cylinder 61 under the action of the rotation of the threaded rod 62. When the moving plate 63 moves from top to bottom, it will squeeze the annular bladder 67 and force the gas inside the annular bladder 67 into the air bladder 57 through the air supply pipe 68, causing the air bladder 57 to inflate. As the gas inside the air bladder 57 increases... When the buoyancy of the airbag 57 in the water increases, it will cause the lifting tank 54 to move upward in the water. Similarly, when the moving plate 63 moves from top to bottom, the moving plate 63 will stretch the annular bladder 67. At this time, the annular bladder 67 can extract the gas in the airbag 57 through the air supply pipe 68. When the gas in the airbag 57 is extracted, the buoyancy provided by the airbag 57 to the lifting tank 54 decreases. At this time, the lifting tank 54 will move downward under the action of gravity. Based on the above process, during the movement of the float plate 11, the lifting tank 54 can move up and down continuously in the surface water. This allows the nozzle to spray the oil film remover evenly in the surface water, thereby ensuring the uniformity of the distribution of the oil film remover in the surface water and improving the oil film removal effect of the oil film remover. It should be noted that when the lifting tank 54 moves up and down, the sliding sleeve 53 and the vertical rod 51 provide constraints for it. In addition, the design of the end cap 52 can prevent the sliding sleeve 53 from falling off the vertical rod 51.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
