Description

Technical Field

[0001] This utility model relates to the field of wetland oxygenation technology, and in particular to an artificial wetland oxygenation device. Background Technology

[0002] In the maintenance of constructed wetland ecosystems, effective oxygenation of the water is crucial. Currently, some constructed wetland oxygenation devices employ advanced spraying technology, which can spray water to higher and wider areas, allowing for greater contact area and longer contact time between the water and air. This increases the oxygen content of the sprayed water to a certain extent, thereby achieving oxygenation of the constructed wetland.

[0003] However, existing oxygenation methods based on spraying technology have significant limitations. Because they mainly rely on the brief contact between water and air to increase oxygen levels, the oxygenation effect is always difficult to achieve the ideal state, failing to fully meet the dissolved oxygen requirements of constructed wetlands, and thus affecting the survival of organisms and the stable operation of the ecosystem within the wetland.

[0004] In addition, during the use of oxygenation and humidification vehicles, attention needs to be paid to the amount of stored water to avoid the water source not being replenished in time. Therefore, an artificial wetland oxygenation device is needed to solve the above problems. Summary of the Invention

[0005] The technical problem this invention aims to solve is that the method of increasing the contact time between water and air and increasing the contact area cannot achieve the desired oxygenation effect.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an artificial wetland oxygenation device, including a humidification cart with universal wheels at the bottom, a U-shaped water tank inside the humidification cart, a water filtration unit in the middle of the water tank, a pump assembly connected to one side of the water tank, and oxygenating algae inside the other side, with the pump assembly side being a closed end and the oxygenating algae side being an open end, a rotating spray structure inside the pump assembly, and a water level sensor in the middle of the water tank.

[0007] Preferably, the water filtration unit includes a first partition and a second partition that are vertically fixed inside the water tank. The pressure pump input end of the water pump assembly passes through the second partition and is located on both sides of the first partition with the oxygenating algae. A filter plate is detachably installed on the inner side of the first partition.

[0008] Preferably, the first partition has an opening in the middle for mounting the filter plate, and a limiter is movably connected to the top of the side wall of the first partition to press the filter plate into the opening.

[0009] Preferably, the limiter is a cam structure, the limiter is horizontally rotatably mounted above the filter plate, and the limiter contacts the filter plate only when the protruding end of the limiter is downward.

[0010] Preferably, the rotating spray structure includes a rotating pipe vertically rotating on the humidification vehicle and a conversion box fitted on the rotating pipe. The conversion box includes an annular base fixed on the humidification vehicle and a cover fastened to the annular base. A sealing structure is provided at the gap between the base and the cover. The cover is fixedly connected to the rotating pipe. The water supply pipe of the pump assembly is connected to the base. A water hole is opened on a section of the rotating pipe located inside the conversion box.

[0011] Preferably, the top of the outer wall of the base is provided with a continuous annular groove, and the inner wall of the cover is provided with a continuous annular protrusion that matches the annular groove.

[0016] This invention provides an artificial wetland oxygenation device, which has the following beneficial effects.

[0017] 1. This artificial wetland aeration device, through the setting of a water tank, aeration bulbs, pressure pump, and nozzles, allows the aeration bulbs to float on the surface of the water tank when the inner cavity of the water tank is filled with a large amount of water.

[0026] Please see Figure 1-5 An artificial wetland aeration device includes: a humidifying vehicle 1, with casters 2 movably connected to the bottom of the humidifying vehicle 1; a water tank 3 opening in the inner cavity of the humidifying vehicle 1; an aeration bulb 4 installed inside the water tank 3; a first partition 5 connected to the inner wall of the humidifying vehicle 1; an opening in the middle of the first partition 5; a filter plate 6 embedded in the inner wall of the opening; a limiter 7 horizontally rotatably connected to the outer wall of the first partition 5; a second partition 8 connected to the inner wall of the humidifying vehicle 1; and an aeration bulb 4 installed inside the inner cavity of the humidifying vehicle 1. There is a pressure pump 9, and a water pipe 10 is connected to the outer wall of the pressure pump 9. A conversion box 11 is fixedly connected to the outer wall of the humidification vehicle 1. A rotary motor 12 is installed on the outer wall of the humidification vehicle 1. A rotary pipe 13 is connected to the top of the rotary motor 12. A water hole 14 is opened on the outer wall of the rotary pipe 13. A spray pipe 15 is connected to the top of the rotary pipe 13. A nozzle 16 is provided on the outer wall of the spray pipe 15. A top cover 17 is placed on the top of the humidification vehicle 1. A handle 18 is connected to the outer wall of the top cover 17.

[0027] like Figure 2 As shown, the inner cavity of the water tank 3 is set in a "U" shape, and the inner cavity of the water tank 3 is filled with water. By setting the inner cavity of the water tank 3 in a "U" shape, the device uses the inner cavity of the water tank 3 to load water, and oxygenating balls 4 are placed on the surface of the water, so that the oxygenating balls 4 in the device float on the surface of the water tank 3.

[0028] like Figure 3 As shown, the filter plate 6 has filter holes on its outer wall, and a limiter 7 limits the outer wall of the filter plate 6. The filter holes on the outer wall of the filter plate 6 allow water in the water tank 3 to be filtered as it passes through the filter plate 6. When the filter plate 6 is installed on the inner wall of the first partition 5, the limiter 7 limits the outer wall of the filter plate 6, preventing it from detaching. The limiter 7 can be rotated to a downward-facing position to limit the filter plate 6, and rotated to an upward-facing position to remove the filter plate 6 for cleaning.

[0029] like Figure 2 As shown, the right side of the pressure pump 9 is connected to a water pump pipe, which extends to the water source. By connecting the right side of the pressure pump 9 to the water pump pipe, the pressure pump 9 is in a waterless environment due to the isolation effect of the second partition 8. When the pressure pump 9 extends to the filtered water source through the water pump pipe, it draws clean water, thereby causing the pressure pump 9 to pump the water source to the water supply pipe 10.

[0030] like Figure 4 As shown, the inner cavity of the water supply pipe 10 is connected to the inner cavity of the conversion box 11, and the water hole 14 is located in the inner cavity of the conversion box 11. Through the connection between the inner cavity of the water supply pipe 10 and the inner cavity of the conversion box 11, when the conversion box 11 is filled with water due to the transport action of the water supply pipe 10, the water source is guided into the inner cavity of the water hole 14 by utilizing the presence of the water hole 14 in the inner cavity of the conversion box 11, and then transmitted to the spray pipe 15 and the nozzle 16.

[0031] like Figure 1 and Figure 5 As shown, there are several nozzles 16, and these nozzles 16 are arranged on the outer wall of the spray pipe 15. The nozzles 16 on the device are set in an oblique shape on the outer wall of the spray pipe 15, so that when spraying is required, the nozzles 16 can spray in front of the device.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the outer wall of the humidification vehicle 1 is provided with a hinge, and the other side of the hinge is connected to the top cover 17. The hinge on the outer wall of the humidification vehicle 1 allows the top cover 17 to be movably connected to one side of the humidification vehicle 1. When the top cover 17 covers the top of the humidification vehicle 1, it blocks the spray from entering the area where the pressure pump 9 is located.

[0033] like Figure 1 , Figure 2 and Figure 5As shown, a water level sensor 19 is installed on the outer wall of the humidification vehicle 1, and the water level sensor 19 is installed at a position higher than the pressure pump 9. Because the water level sensor 19 is installed on the outer wall of the humidification vehicle 1, the water level will continuously drop when the pressure pump 9 pumps the water source in the inner cavity of the device. At this time, the water level sensor 19 continuously detects the water level height, so that when the water level in the inner cavity of the device drops, the water level sensor 19 detects that the water level is too low and promptly reminds the staff to add water.

[0034] Working principle: First, by setting up a water tank 3, oxygenating bulbs 4, a pressure pump 9, and nozzles 16, the inner cavity of the water tank 3 is filled with a large amount of water. The oxygenating bulbs 4 float on the surface of the water tank 3 and oxygenate the water while performing photosynthesis, releasing a large amount of oxygen into the water. Under the action of the pressure pump 9, the nozzles 16 spray water with a high oxygen content. Then, by setting up a first partition 5, a filter plate 6, a water level sensor 19, and a pressure pump 9, the pressure pump 9 draws clean water that has been filtered by the filter plate 6 inside the first partition 5. The pressure pump 9 delivers water with a high oxygen content and free of impurities to the conversion box 11 and the nozzles 16. As the water level in the device continuously drops, the water level sensor 19 detects the change in water level to avoid the problem of insufficient water in the device.
