Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, and in particular to a water environment treatment device. Background Technology

[0002] In recent years, the improper discharge of large amounts of domestic sewage and industrial wastewater into natural or semi-natural water bodies such as rivers, ditches, and lakes has significantly reduced the self-purification capacity of these water bodies, leading to the rapid accumulation of nutrients such as nitrogen and phosphorus. This provides the necessary nutrients for duckweed growth. Furthermore, factors such as slow flow velocity, sunlight, and water temperature easily cause large amounts of duckweed and other floating debris to accumulate on the water surface. This phenomenon is also prone to occur in ecological landscapes and hydraulic structures in sewage and water treatment plants. Duckweed not only affects production and human perception, but especially when large amounts of duckweed accumulate or proliferate in water bodies (a manifestation of eutrophication), even covering the entire or part of the water surface, duckweed will hinder water reoxygenation and the absorption of sunlight by submerged plants, leading to the death of submerged plants. When duckweed becomes dominant, the water quality will gradually decline. In severe cases, it can lead to oxygen depletion in the water, affecting the aquatic ecosystem and disrupting the aquatic ecological balance.

[0003] Currently, the main methods for removing duckweed include manual removal, application of chemical agents or biological agents, and in-situ bioremediation. While chemical agents and biological agents are fast-acting, they have side effects and can negatively impact plant and animal growth. In-situ bioremediation is relatively safe and environmentally friendly, but it is slow to take effect and has a long cycle. Therefore, manual removal is still the most common method. However, manual removal is inefficient and costly, and the work of cleaning duckweed in lakes and other bodies of water poses significant safety hazards and is highly unsafe, increasing the risk of accidents. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a water environment treatment device to solve the problems of low efficiency and safety of manual duckweed removal.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0006] A water environment treatment device includes four suspended bodies, a cover, an absorption assembly, and a mesh frame. The cover includes a main body with a U-shaped extrusion body at its bottom. A gear column with teeth is fixedly connected to the center of the bottom of the main body. A first support rod is connected to the outside of the main body, angled outwards and downwards, with its bottom ends fixedly connected to the suspended bodies. The absorption assembly includes a U-shaped frame plate and a box. The bottom of the box has a receiving section communicating with the box. The receiving section is fixedly connected to the U-shaped frame plate via a second support rod. A flow channel with a thickness equal to that of the U-shaped extrusion body is provided between the U-shaped frame plate and the box. A sealing plate is rotatably connected to the four edges of the bottom of the box, and a spring is fixedly connected to the bottom of the sealing plate. The other end is fixedly connected to the bottom of the box. Under the elastic force of the spring, the four sealing plates can block the flow channel between the box and the U-shaped frame plate. A gearbox is provided inside the box. The gearbox is fixedly connected to the box through a third support rod. A stepper motor is fixedly connected to the outside of the gearbox. The output shaft of the stepper motor passes through the side wall of the gearbox. A drive wheel is fixedly connected to the end of the output shaft of the stepper motor. Two driven wheels are symmetrically arranged inside the gearbox. The two driven wheels mesh with the drive wheel. A rotating wheel is fixedly connected to the rotating shaft of the driven wheel. The gear column passes through the box and through the gearbox and meshes with the rotating wheel. The bottom end of the gear column can be stored in the storage part. The mesh frame is located at the bottom of the U-shaped frame plate. The mesh frame and the U-shaped frame plate are detachably connected.

[0007] Based on the above technical solution, the present invention has made the following improvements:

[0008] Furthermore, the spring is covered with a soft rubber sleeve, the two ends of which are fixedly connected to the bottom of the housing and the bottom of the sealing plate, respectively. The rubber sleeve seals the spring internally, preventing it from being entangled by foreign objects, and also provides waterproofing and prevents the spring from rusting.

[0009] Furthermore, the sealing plate has a soft rubber layer at its tail end. When the sealing plate contacts the U-shaped frame plate, the rubber layer is located between the sealing plate and the U-shaped frame plate, which can better block the flow channel between the U-shaped frame plate and the box body, resulting in a better blocking effect.

[0010] Furthermore, a sealing film sleeve is connected between the bottom of the main body and the top of the housing. The sealing film sleeve can seal the top of the housing, thus providing waterproofing and preventing liquid from flowing into the gearbox from the top of the housing.

[0011] Furthermore, a traction rope is connected to the outside of the U-shaped frame plate. The traction rope can secure the equipment, preventing it from drifting away and facilitating its retrieval.

[0012] Furthermore, the main body is a hollow, cube-shaped structure. The hollow design of the cover reduces weight, makes it easier to lift, and facilitates levitation of the device.

[0013] Furthermore, the suspended body is positioned on the outer edge of the diagonal of the cover. This reduces the interference of the suspended body on the flow direction of the duckweed.

[0014] The beneficial effects of this invention are as follows: Under the action of the suspending body, the cover is suspended above the horizontal plane. The rotating wheel and the gear column mesh. Driven by the stepper motor, the suction assembly can move up and down along the gear column. When the suction assembly moves downward, the top of the U-shaped frame plate is below the horizontal plane. At this time, duckweed flows into the flow channel between the U-shaped frame plate and the box with the water. When the suction assembly moves upward, the U-shaped extrusion body is inserted into the flow channel between the U-shaped frame plate and the box. The U-shaped extrusion body extrudes the water and duckweed in the flow channel. Forced to squeeze the sealing plate, the sealing plate is opened, and water and duckweed flow into the net frame. When the suction component moves upward again, the sealing plate returns to its initial state. The duckweed and water squeezed into the net frame are blocked below by the sealing plate, and the net frame holds the duckweed in place. With the continuous up and down movement of the suction component, the duckweed on the water surface automatically flows into the U-shaped frame plate, thus automatically cleaning the duckweed and floating objects on the water surface without manual cleaning, making it safer. Moreover, duckweed and other suspended objects can flow to the device with the water without external force, making the cleaning more thorough. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 5 As shown

[0024] A water environment treatment device includes a suspended body 1, a cover 2, an absorption component 3, and a mesh frame 4. The suspended body 1 is a hollow sphere, and there are four suspended bodies 1.

[0025] The cover 2 includes a body 21, which is rectangular or preferably square. The bottom of the body 21 is provided with a U-shaped extrusion body 22, the outer side wall of which is flush with the outer side wall of the body 21. A gear column 23 is fixedly connected to the center of the bottom of the body 21. The gear column 23 is vertically arranged and has teeth on its two symmetrical side walls. A first support rod 24 is connected to the outside of the body 21. The first support rod 24 is arranged obliquely outward and downward, and the bottom end of the first support rod 24 is fixedly connected to the suspension body 1.

[0026] The absorption component 3 includes a U-shaped frame plate 31 and a box body 32. The box body 32 has an opening at the top and a storage section 33 at the bottom. The storage section 33 is vertically arranged and communicates with the box body 32. The storage section 33 is fixedly connected to the U-shaped frame plate 31 via a second support rod 34. A flow channel 35 with the same thickness as the U-shaped extrusion body 22 is provided between the U-shaped frame plate 31 and the box body 32. The top of the U-shaped frame plate 31 is lower than the top of the box body 32. The vertical length of the U-shaped frame plate 31 is... The length of the sealing plate 36 is longer than the vertical length of the box body 32. Sealing plates 36 are rotatably connected to the four edges of the bottom of the box body 32. A spring 37 is fixedly connected to the bottom of each sealing plate 36, and the other end of the spring 37 is fixedly connected to the bottom of the box body 32. Under the elastic force of the spring 37, the four sealing plates 36 can block the flow channel 35 between the box body 32 and the U-shaped frame plate 31. The sealing plates 36 are divided into two groups, and the two groups of sealing plates 36 are staggered vertically. Two symmetrical sealing plates 36 on the same plane constitute one group.

[0027] A gearbox 38 is housed inside the housing 32. The gearbox 38 has openings at both its upper and lower ends. The gearbox 38 is fixedly connected to the housing 32 via a third support rod 39. A stepper motor 381 is fixedly connected to the outside of the gearbox 38. A power supply and controller are housed inside the housing 32. After power is turned on, the stepper motor 381 reciprocates in both forward and reverse directions under the control of the controller. The output shaft of the stepper motor 381 passes through the side wall of the gearbox 38, and an actuator is fixedly connected to the end of the output shaft of the stepper motor 381. The gearbox 38 contains two driven gears 383 symmetrically arranged inside the gearbox 38. The two driven gears 383 are connected to the housing 32 by bearings and mesh with the driving gear 382. A rotating wheel 384 is fixedly connected to the rotating shaft of the driven gear 383. The gear column 23 passes through the opening at the top of the housing 32 and through the opening at the top of the gearbox 38 to mesh with the rotating wheel 384. The bottom end of the gear column 23 passes through the opening at the bottom of the gearbox 38 and is inserted into the storage part 33.

[0028] The wire frame 4 is located at the bottom of the spiral frame plate 31, and the wire frame 4 is bolted to the spiral frame plate 31.

[0029] Under the action of the suspending body 1, the cover 2 is suspended above the horizontal plane. Driven by the stepper motor 381, when the absorption component 3 moves downward, the top of the U-shaped frame plate 31 is below the horizontal plane. At this time, duckweed flows into the flow channel 35 between the U-shaped frame plate 31 and the box 32 with the water. When the absorption component 3 moves upward, the U-shaped extrusion body 22 is inserted into the flow channel 35 between the U-shaped frame plate 31 and the box 32. The U-shaped extrusion body 22 extrudes the water and duckweed in the flow channel 35, and the water is forced to squeeze the sealing plate 36. When the sealing plate 36 is opened, water and duckweed flow into the net frame 4. When the suction component 3 moves upward again, the sealing plate 36 returns to its initial state. The duckweed and water squeezed into the net frame 4 are blocked at the bottom by the sealing plate 36. The net frame 4 holds the duckweed in place. With the continuous up and down movement of the suction component 3, the duckweed on the water surface automatically flows into the U-shaped frame plate 31, thereby automatically cleaning the duckweed and floating objects on the water surface. The device has a simple structure and is easy to operate. After starting the device, simply place it in the water. The duckweed and other suspended objects will automatically flow towards the device under the influence of the water.

[0030] Specifically, the spring 37 is covered with a soft rubber sleeve, and the two ends of the rubber sleeve are fixedly connected to the bottom of the housing 32 and the bottom of the sealing plate 36, respectively. The rubber sleeve seals the spring 37 inside, preventing the spring 37 from being entangled by foreign objects.

[0031] Specifically, the tail end of the sealing plate 36 is provided with a soft rubber layer. When the sealing plate 36 contacts the U-shaped frame plate 31, the rubber layer is located between the sealing plate 36 and the U-shaped frame plate 31, and the rubber layer can block the gap between the sealing plate 36 and the U-shaped frame plate 31, resulting in a better sealing effect.

[0032] Specifically, a sealing film sleeve 5 is connected between the bottom of the main body 21 and the top of the box 32. The sealing film sleeve 5 can seal the top of the box 32 to prevent foreign objects from entering the box 32.

[0033] Specifically, a traction rope 6 is connected to the outside of the U-shaped frame plate 31. The traction rope 6 can secure the equipment, preventing it from drifting away and facilitating its retrieval.

[0034] Specifically, the main body 21 is a hollow, cube-shaped body. The hollow design of the cover 2 reduces weight, makes it easier to lift, and facilitates the levitation of the device.

[0035] Specifically, the suspended body 1 is positioned on the outer edge of the diagonal of the cover 2. This reduces the interference of the suspended body 1 with the flow direction of the duckweed.

[0036] The method of using this invention is as follows: After starting the device, throw it into the water and place it in a place where duckweed accumulates in large quantities. Under the action of the suspension body 1, the cover 2 is suspended above the horizontal plane. Driven by the stepper motor 381, the suction component 3 can move up and down along the gear column 23. When the suction component 3 moves downward, the top of the U-shaped frame plate 31 is below the horizontal plane. At this time, the duckweed flows into the flow channel 35 between the U-shaped frame plate 31 and the box 32 with the water. When the suction component 3 moves upward, the U-shaped extrusion body 22 inserts into the U-shaped frame plate 31 and the box 32. In the flow channel 35 between the boxes 32, the U-shaped extrusion body 22 extrudes the water and duckweed in the flow channel 35. The water is forced to squeeze the sealing plate 36, and the sealing plate 36 is opened. The water and duckweed flow into the mesh frame 4. When the absorption component 3 moves upward again, the sealing plate 36 returns to its initial state. The duckweed and water squeezed into the mesh frame 4 are blocked below by the sealing plate 36. The mesh frame 4 holds the duckweed in place. With the continuous up and down movement of the absorption component 3, the duckweed on the water surface automatically flows into the U-shaped frame plate 31, thereby automatically cleaning the duckweed and floating objects on the water surface.
