Description

An in-situ purification device and method for urban wetlands Technical Field

[0001] This invention relates to the field of wetland purification technology, specifically to an in-situ purification device and method for urban wetlands. Background Technology

[0002] Urban wetlands are an indispensable part of the urban ecological and cultural system. Currently, urban wetland water sources are usually treated with purification devices.

[0003] Existing purification devices typically use floating beds, which purify urban wetland water by arranging biological fillers and aquatic plants on the floating beds. Although this method is low in cost and has a high purification capacity, the aquatic plants on the floating beds are subject to significant wind impact during strong winds, and the floating beds cannot provide protection for them, resulting in damage to the aquatic plants and reducing the purification effect of the floating beds on the water. Therefore, we propose an in-situ purification device and method for urban wetlands. Summary of the Invention

[0004] The purpose of this invention is to provide an in-situ purification device and method for urban wetlands to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The side wall of the filter pool is provided with a second water outlet corresponding to the aquatic plant area. The output end of the pump body is provided with a pipe. The pump body is used to draw water from the placed water area and input it into the filter pool through the pipe. After being filtered by the filter pool, the water is discharged through the second water outlet and passes through the aquatic plant area. After being treated by the aquatic plants in the aquatic plant area, it flows back into the placed water area.

[0007] It also includes a windbreak assembly on the top surface of the floating platform. The windbreak assembly includes an annular guide rail on the outer ring of the aquatic plant area, a V-shaped windbreak plate slidably mounted on the annular guide rail, and a wind-resistant drive unit mounted on the pipe to drive the V-shaped windbreak plate to move along the annular guide rail. The wind-resistant drive unit is used to drive the V-shaped windbreak plate to correspond to the wind direction, so that the V-shaped windbreak plate provides wind protection for the aquatic plants facing the wind direction.

The pipe body one vertically and movably passes through the mesh frame and the floating platform. A pipe body two is movably sleeved on the outside of the pipe body one. The pipe body two is vertically fixed on the floating platform. A water outlet part one is provided on the outer wall of the pipe body two above the annular filter screen.

[0011] A further improvement is that the wind-driven component includes a wind vane mounted on the top of the second tube via a rotating shaft, a movable disk rotatably mounted on the top of the second tube and fitted around the outer ring of the rotating shaft, a connecting frame connecting the movable disk and the V-shaped wind deflector, an infrared receiver mounted on the movable disk, and an infrared transmitter mounted on the wind vane. When the infrared transmitter and the infrared receiver are directly aligned, the direction of the wind vane corresponds to the direction of the tip of the V-shaped wind deflector. The second tube is equipped with a rotating device and an electrical assembly via a bracket. The output end of the rotating device is equipped with a drive gear, and the bottom of the movable disk is equipped with a gear ring that meshes with the drive gear ring. The electrical assembly includes a controller. When the infrared receiver does not receive an infrared signal from the infrared transmitter, it sends a signal to the controller, causing the controller to control the rotating device to operate.

[0012] A further improvement is that ventilation openings are provided on both sides of the V-shaped windbreak, and a sealing part is provided at the ventilation opening. A pulling part is provided on the connecting frame, and the pulling part drives the sealing part to control the opening and closing degree of the ventilation opening according to the wind force.

[0018] S1: Place this device in the water to be purified;

[0019] S2: Turn on the pump body. The pump body draws water from the placement area and inputs it into the filter tank through the pipe fittings.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please refer to Figure 1. An in-situ purification device for urban wetlands includes a mesh frame 1, a pump body 6, and a floating platform 5. The top surface of the floating platform 5 is provided with a filter pool 9. The outer ring of the filter pool 9 is provided with an aquatic plant area for planting aquatic plants 15. The plants purify the water body by utilizing their roots, leaves, and stems, while also increasing the aesthetics. The side wall of the filter pool 9 is provided with a second water outlet 13 corresponding to the aquatic plant 15 area. The second water outlet 13 is, for example, a pipe with a water outlet hole at the bottom.

[0029] Biological packing material is suspended inside the mesh frame 1. The biological packing material extends into the water body to purify the water with microorganisms. This is existing technology and will not be described in detail here. The output end of the pump body 6 is equipped with a pipe fitting. The pump body 6 is used to draw water from the placement area and input it into the filter tank 9 through the pipe fitting. After being filtered by the filter tank 9, the water is discharged through the outlet 13 and passes through the aquatic plant area. After being treated by the aquatic plants 15 in the aquatic plant area, it flows back into the placement area. During the process of the water being drawn back, the dissolved oxygen concentration can also be increased.

[0030] It also includes a windbreak assembly on the top surface of the floating platform 5. The windbreak assembly includes an annular guide rail 14 located around the outer ring of the aquatic plant 15 area, a V-shaped windbreak plate 19 slidably mounted on the annular guide rail 14, and a wind-resistant drive component mounted on the pipe fitting to drive the V-shaped windbreak plate 19 to move along the annular guide rail 14. The wind-resistant drive component drives the V-shaped windbreak plate 19 to align with the wind direction, so that the V-shaped windbreak plate 19 provides wind protection for the aquatic plants 15 facing the wind. Through this arrangement, the aquatic plants 15 facing the wind are prevented from being damaged by strong winds, thus affecting the purification of the wetland. Setting the V-shaped windbreak plate 19 to align with the wind direction can guide and disperse the oncoming airflow to the side.

[0031] Preferably, in this embodiment, the pump body 6 is mounted inside the mesh frame 1 via a bracket. The mesh frame 1 can block larger particles in the water, preventing pipe blockage. The bottom of the mesh frame 1 is provided with an insert 2, which is an insertion cone, to improve the stability of the device in the water. The mesh frame 1 is provided with a counterweight 3 to improve the stability of the device. T-shaped guide rods 4 are movably inserted around the top surface of the mesh frame 1, and the top of the T-shaped guide rods 4 is connected to a floating platform 5. The floating platform 5 moves relative to the mesh frame 1 with the water level. The floating platform 5 is provided with seepage holes 16 at the position corresponding to the aquatic plant area so that the liquid flows back down into the water area.

[0032] Preferably, the top surface of the filter pool 9 in this embodiment is provided with an annular filter screen 11 for filtering the incoming water, and a liquid guiding cavity 10 communicating with the water outlet component 13 is provided inside the filter pool 9.

[0033] Preferably, the pipe fittings in this embodiment include a pipe body 7 connected to the output end of the pump body 6. The pipe body 7 vertically and movably passes through the mesh frame 1 and the floating platform 5. A pipe body 8 is movably sleeved on the outside of the pipe body 7. The pipe body 8 is vertically fixed on the floating platform 5. A water outlet 12 is provided on the outer wall of the pipe body 8 above the annular filter screen 11. Both the pipe body 7 and the pipe body 8 are rigid pipes. The water outlet 12 is the same as the water outlet 23. The pipe body 8 moves relative to the pipe body 7 with the floating platform 5.

[0034] Please refer to Figures 2-3. Preferably, the wind-driven component of this embodiment includes a wind vane 22 mounted on the top of the second tube 8 via a rotating shaft, a movable disk 17 rotatably mounted on the top of the second tube 8 and fitted around the outer ring of the rotating shaft, a connecting frame 24 connecting the movable disk 17 and the V-shaped wind deflector 19, an infrared receiver 23 mounted on the movable disk 17, and an infrared transmitter mounted on the wind vane 22. When the infrared transmitter and the infrared receiver 23 are directly opposite each other, the direction of the wind vane 22 corresponds to the direction of the tip of the V-shaped wind deflector 19. A rotating device 18 and an electrical assembly 21 are mounted on the second tube 8 via a bracket. The output end of the rotating device 18 is provided with a drive gear. The bottom of the movable disk 17 is provided with a gear ring 20 that meshes with the drive gear ring 20. A controller is provided in the electrical assembly 21. When the infrared receiver 23 does not receive an infrared signal from the infrared transmitter, it sends a signal to the controller, causing the controller to control the rotating device 18 to work. The wind vane 22 rotates to point towards the airflow blowing towards the device. The infrared receiver 23 and the infrared transmitter work together to drive the rotating device 18 to rotate the movable plate 17. The movable plate 17 drives the V-shaped wind deflector 19 to move synchronously through the connecting frame 24, so that the V-shaped wind deflector 19 blocks the airflow blowing towards the aquatic plants in the same direction as the wind. It should be noted that the electrical component 21 also includes a battery device and a wireless data transmission device, etc., to power the electrical components of this application and to facilitate remote control. Of course, this application can also set a hydroelectric generator or photovoltaic module as the electrical component function of this application, which will not be described in detail here.

[0035] Preferably, the V-shaped windbreak plate 19 of this embodiment has ventilation openings 25 on both sides, and a sealing part is provided at the ventilation opening 25. The connecting frame 24 is provided with a pulling part. The pulling part drives the sealing part to control the opening and closing degree of the ventilation opening 25 according to the wind force. When the outside wind force is small, such as a light breeze, the airflow can pass through the ventilation opening 25 normally and blow towards the aquatic plants 15, improving the growth quality of the aquatic plants 15 and enabling the aquatic plants 15 to grow better. When the outside wind force is large, such as a strong wind, the pulling part causes the sealing part to gradually close the ventilation opening 25, so that the airflow cannot pass through the ventilation opening 25 or the airflow through the ventilation opening 25 is small, avoiding damage to the aquatic plants 15.

[0036] Preferably, the enclosure in this embodiment includes two sets of sealing plates 30 located at the upper and lower ends of the vent 25 respectively. Both sets of sealing plates 30 are slidably disposed on the inner outer wall of the V-shaped baffle 19. Both sets of sealing plates 30 are provided with vertical racks 31. A driven gear 32 is provided between the two sets of racks 31. The driven gear 32 is rotatably disposed on the side wall of the V-shaped baffle 19 through a shaft. With this arrangement, the two sealing plates 30 can move synchronously closer to each other or synchronously farther away from each other.

[0037] Preferably, the pulling part in this embodiment includes a sliding opening formed on the connecting frame 24 along its length. A sliding block is provided inside the sliding opening, and the sliding block has an I-shaped vertical cross-section. A wind-facing plate 26 is provided on the top of the sliding block. One side of the sliding block is connected to the inner wall of one side of the sliding opening through an elastic element 27, which is a spring. A V-shaped frame 33 is provided at the bottom of the sliding block, and pull ropes 29 are connected to both ends of the V-shaped frame 33. The other ends of the two sets of pull ropes 29 are respectively connected to two sets of sealing plates 30 below. A guide frame 28 is provided on the top of the V-shaped windbreak plate 19 for the pull ropes 29 to pass through. In strong winds, the strong wind blows the wind-facing plate 26 to move and compress the elastic element 27. The movement of the wind-facing plate 26 drives the sliding block, and the sliding block drives the pull ropes 29 through the V-shaped frame 33. The V-shaped frame 33 causes the two sets of sealing plates 30 to gradually move closer to each other, reducing the airflow entering from the vent 25 and reducing damage to the aquatic plants 15.

[0038] The top of the windward plate 26 has a groove, and a counterweight column 261 is placed in the groove. Users can add or remove the counterweight column 261 as needed so that the windward plate 26 can be moved according to the wind force.

[0039] Preferably, in this embodiment, the inner side of the V-shaped baffle 19 is provided with a plate 34 perpendicular to the tube body 8. The other end of the plate 34 extends to the inner side of the annular filter 11. The bottom of the plate 34 is provided with bristles 35 that fit against the top of the annular filter 11. When the V-shaped baffle 19 moves along the annular guide rail 14, the V-shaped baffle 19 drives the plate 34 to move in a circular motion around the annular filter 11. The plate 34 rubs the annular filter 11 with the bristles 35, thereby cleaning the annular filter 11.

[0041] S1: Place this device in the water to be purified;

[0042] S2: Open pump body 6. Pump body 6 draws water from the placement area and inputs it into filter tank 9 through pipe fittings. After being filtered by filter tank 9, the water is discharged through outlet part 13 and passes through aquatic plant area. After being treated by aquatic plants 15 in aquatic plant area, it flows back into the placement area.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
