Description

Technical Field

[0001] The present invention relates to the technical field of wetland restoration, and in particular to a water purification system for natural wetland ecological restoration. Background Art

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

[0003] After searching, the Chinese patent with announcement number CN221971378U discloses a wetland water ecological purification system, including a fixed plate, a purification mechanism for purifying water quality is provided at the upper end of the fixed plate, the purification mechanism includes a functional chamber, a filler layer, and a groove, the functional chamber is fixedly provided at the upper end of the fixed plate, a filler layer is provided inside the functional chamber, a plurality of grooves are evenly provided on the surface of the filler layer, a buoyancy mechanism for providing buoyancy for the device is provided at the lower end of the fixed plate, the buoyancy mechanism includes a fixed frame and a buoyancy cavity, a fixed frame is fixedly provided at the lower end of the fixed plate, and a buoyancy cavity is fixedly provided inside the fixed frame. The above scheme directly floats the entire device on the wetland, thereby filtering the water quality of the wetland, and utilizing aquatic plants to absorb and consume nitrogen and phosphorus in the water to prevent eutrophication of the wetland water, and because it is easy to build, it can be easily promoted and used. However, the above scheme still has the following shortcomings in actual use:

[0004] Although the water purification device proposed in the above scheme has the function of preventing eutrophication of water bodies, it cannot remove the oil floating on the water surface. The main reasons for the generation of oil floating objects on the surface of natural wetlands include industrial emissions, algae reproduction and death, excessive organic matter and natural factors. These oil floating objects will have many disadvantages on the wetland ecosystem. The oil film on the water surface will hinder sunlight, affect the photosynthesis of algae, reduce the oxygen production of zooplankton, and at the same time block the gas exchange at the interface between air and water, resulting in deterioration of water quality and reduced dissolved oxygen content, which is usually accompanied by excessive water quality indicators and poor bottom soil. Aquatic animals living in such an environment for a long time have decreased resistance to disease and are prone to disease. In addition, oil floating objects will also emit odor to the surrounding area, and the demand for optimizing the appearance of the water body cannot be met, which seriously affects the effect of water ecological management.

The underwater actuator drives the floating plate to move, driving the lifting tank to move on the water surface. The oil film remover can be evenly sprayed into the surface water as the lifting tank moves, thereby effectively removing the oil film on the water surface and improving work efficiency and purification effect.

[0025] 2. The present invention also features an air supply assembly. The movement of the floating plate drives the propeller blades, which in turn drives the threaded rods to rotate, causing the movable plate to move up and down within the mounting tube, squeezing or stretching the annular bladder. The amount of gas within the bladder is adjusted via the air supply pipe, thereby changing the buoyancy of the lifting tank in the water, causing it to continuously move up and down within the surface water. This design enables the spray holes 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 directly driven by the rotation of the propeller blades in the water when the float moves. Because 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, which not only simplifies the system structure, reduces the complexity and manufacturing cost of the equipment, but also reduces energy consumption.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

A socket 24 is opened at the top position of the side of the storage box 21;

[0039] A pressing assembly is provided inside the storage box 21 for pressing the oil film removal agent out of the storage box 21. The pressing assembly includes a pressing plate 31 and a counterweight 33.

[0040] When the natural wetland ecological restoration water purification system proposed by the present invention is used, the staff first puts the oil film remover into the storage box 21. In the initial state, the through hole 45 on the sliding plate 44 is arranged opposite to the installation hole 34 on the pressure plate 31. The staff can inject the oil film remover into the storage box 21 through the installation hole 34 and the through hole 45 that overlap with each other. In addition, the limiting plate 43 is inserted into the socket 24 and extends to the interior of the storage box 21. The pressure plate 31 is placed on the limiting plate 43. At this time, the pressure plate 31 is located at the top of the storage box 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 for controlling the pressing assembly. The control assembly includes a mounting frame 41, a pull rod 42, a limit plate 43, a sliding plate 44 and a limit frame 46. The mounting frame 41 is fixed to the side of the storage box 21, and the mounting frame 41 is L-shaped. The pull rod 42 passes through the mounting frame 41 and is slidably connected to the mounting frame 41. One end of the pull rod 42 is fixedly connected to the limit plate 43. The limit plate 43 slides in the socket 24. The sliding plate 44 is arranged on the pressure plate. 31 top surface, the bottom surface of the sliding plate 44 and the top surface of the pressing plate 31 are in contact with each other, and the sliding plate 44 is made of rubber material, the limiting frame 46 is fixed to the top surface of the pressing plate 31, the sliding plate 44 is slidably set in the limiting frame 46, the sliding plate 44 is provided with a through hole 45, a connecting rod 47 is fixed to the pull rod 42, a magnetic block 48 is fixed to the end of the connecting rod 47 away from the pull rod 42, and a magnetic plate 49 is fixed to the side of the sliding plate 44, and the magnetic block 48 and the magnetic plate 49 are attracted to each other;

[0042] The bottom surface of the floating plate 11 is provided with a delivery assembly for delivering the oil film removal agent into the water, the delivery assembly includes a lifting tank 54, the lifting tank 54 is connected to the end of the connecting pipe 22 away from the storage box 21, the delivery assembly also includes a vertical rod 51, an end cap 52, a sliding sleeve 53, an opening 55, a partition 56 and an air bag 57, the vertical rod 51 is fixed to the bottom surface of the floating plate 11, the end cap 52 is fixed to the end of the vertical rod 51 away from the floating plate 11, the sliding sleeve 53 is provided on the vertical rod 51, and the sliding sleeve 53 is connected to the lifting tank 54, the opening 55 is provided on the lifting tank 54, the partition 56 is slidably provided inside the lifting tank 54, the outer peripheral surface of the partition 56 is in contact with the inner surface of the lifting tank 54, one end of the air bag 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 position of the lifting tank 54, and the opening 55 is located below the partition 56;

[0043] After placing the floating plate 11, the staff pulls the handle on the pull rod 42 to move the pull rod 42. When the pull rod 42 moves, it can drive the limit plate 43 to move. At the same time, the pull rod 42 can also drive the connecting rod 47 to move, so that the connecting rod 47 drives the sliding plate 44 to move until the through hole 45 on the sliding plate 44 is completely staggered with the installation opening 34. At this time, the sliding plate 44 will block the installation opening 34. When the sliding plate 44 completely blocks the installation opening 34, the staff continues to pull the pull rod 42, so that the pull rod 42 continues 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 pressing plate 31 can move downward inside the storage box 21 under the action of the gravity of the counterweight block 33. When the pressing plate 31 moves downward, the pressing plate 31 can press down the oil film remover in the storage box 21. The oil film remover 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, thereby realizing automatic addition of the oil film remover;

[0044] After the staff pulls the pull rod 42, the underwater drive 12 is started. Figure 1 As shown, the underwater driver 12 is used to drive the floating plate 11 to move on the water surface. The specific structure and working principle of the underwater driver 12 are existing technologies, and the implementation method adopts conventional means, which will not be described in detail here. The floating plate 11 will move on the water surface under the action of the underwater driver 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 synchronously performs the spraying action of the oil film remover, which allows the oil film remover to be evenly distributed in the surface water of the water area, thereby eliminating the oil film floating on the water surface. The specific principle of the oil film remover to eliminate the oil film is existing technology, and will not be described in detail here.

[0045] When the pressing plate 31 is lowered, the sliding plate 44 thereon is lowered accordingly. The sliding plate 44 and the connecting rod 47 are connected to each other through the magnetic block 48 and the magnetic plate 49 that are attracted to each other. When the pressing plate 31 moves downward, 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 pressing 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 for it to ensure the stability of the movement of the sliding plate 44. Secondly, the bottom surface of the sliding plate 44 is in contact with the top surface of the pressing plate 31, 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 opening 34.

[0046] An air supply assembly is provided on the side of the floating plate 11. The air supply assembly is used to control the up and down movement of the lifting tank 54. The air supply assembly includes a mounting cylinder 61, a threaded rod 62, a movable plate 63, a propeller blade 66 and an annular bag 67. The mounting cylinder 61 is fixed to the side of the floating plate 11 by a bracket, and the mounting cylinder 61 is arranged in the vertical direction. The threaded rod 62 is rotatably mounted inside the mounting cylinder 61. The end of the threaded rod 62 extends to the outside of the mounting cylinder 61 and is connected to the propeller blade 66. The movable plate 63 is threadedly sleeved on the threaded rod 62. The mounting cylinder 61 A limiting opening 65 is provided on the outer circumference of the movable plate 63, and a limiting block 64 is fixed on the outer circumference of the movable plate 63. The limiting ring slides in the limiting opening 65. One end of the annular capsule 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 capsule 67, and the threaded rod 62 and the annular capsule 67 do not contact each other. An air supply pipe 68 is connected to the annular capsule 67, and one end of the air supply pipe 68 away from the annular capsule 67 is connected to the air bag 57. The mounting cylinder 61, the threaded rod 62 and the movable plate 63 are coaxially arranged;

[0047] In order to ensure the uniformity of the distribution of the oil film remover in the surface water of the water area, the present invention also designs an air supply component for driving 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, when the floating plate 11 moves, the mounting tube 61 moves accordingly, and the propeller blade 66 below the mounting tube 61 is immersed in the water. Therefore, the propeller blade 66 can rotate under the action of water resistance during the movement of the water, and drive the threaded rod 62 to rotate. Under the restriction of the limit port 65 and the limit block 64, the movable plate 63 cannot rotate with the threaded rod 62. Therefore, the movable plate 63 will move up and down inside the mounting tube 61 under the rotation of the threaded rod 62. When the movable plate 63 moves from top to bottom, the movable plate 63 will squeeze the annular bag 67 and press the gas in the annular bag 67 into the air bag 57 through the air supply pipe 68, so that the air bag 57 is inflated. When the gas inside the air bag 57 increases When the floating plate 11 moves, the buoyancy of the airbag 57 in the water increases, which will drive the lifting tank 54 to move upward in the water. Similarly, when the movable plate 63 moves from top to bottom, the movable plate 63 will stretch the annular bag 67. At this time, the annular bag 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 again under the action of gravity. Based on the above process, during the movement of the floating plate 11, the lifting tank 54 can continuously move up and down in the surface water body, which enables the spray hole to evenly spray the oil film remover in the surface water body, thereby ensuring the uniformity of the distribution of the oil film remover in the surface water body, thereby improving the oil film remover's effect on eliminating the oil film. It should be noted that when the lifting tank 54 moves up and down, the sliding sleeve 53 and the vertical rod 51 provide it with constraints. 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 specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
