DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figure 1-Figure 5 This embodiment provides an aeration and pollution purification device for water environment restoration, including a floating unit 100, an aeration unit 200 and a power unit 300.

[0032] The floating unit 100 includes a float 110 and a float drum 120 and a recovery drum 130 coaxially arranged in the float 110 . A connecting ear 180 is welded on the float 110 . One end of the float drum 120 has an opening. The recovery drum 130 is slidably installed in the float drum 120 .

[0033] Preferably, the float 110 is disc-shaped to reduce material stress, and a second through hole 111 is provided in the middle thereof. An airbag 112 is installed in the second through hole 111. The airbag 112 has a valve pipe 113 for controlling the inflow and outflow of gas. The airbag 112 is made of a lightweight material with high elasticity and pressure resistance, such as special rubber or flexible plastic. The buoyancy of the device is adjusted by inflation and exhaust of the valve pipe 113, thereby improving its flexibility in underwater operations.

[0034] It should be noted that, in the original state, the opening height of the recovery tube 130 is slightly higher than the floating tube 120. On the one hand, the water surface tension can be changed by the up and down movement of the recovery tube 130, so that the water body can flow into the recovery tube 130. On the other hand, it can effectively block the continuous entry of water and achieve a filtering effect.

[0035] The aeration unit 200 includes a connecting tube 210, an extension tube 220 and an air pipe 230. The connecting tube 210 is located on the side of the floating tube 120 away from the outlet and is fixedly connected to the floating tube 120 with a second water inlet pipe 240. A one-way valve is installed in the second water inlet pipe 240, so that the water in the connecting tube 210 can only be pumped into the floating tube 120 under the influence of negative pressure but cannot flow back. The extension tubes 220 are arranged equidistantly along the circumferential direction of the connecting tube 210 and are connected to the inside of the connecting tube 210, so that the aerated gas can be dispersed into the water to improve the aeration effect. One end of the air pipe 230 passes through the floating tube 120 and is located in the connecting tube 210, and the other end of the air pipe 230 is used for an external air source.

[0036] The power unit 300 includes a sealing cylinder 310, a first water inlet pipe 320, a motor 330 and a connecting piece 340. The first water inlet pipe 320 is fixedly installed on a side of the connecting cylinder 210 away from the floating cylinder 120 and passes through the inside of the connecting cylinder 210. A conveying paddle 321 is rotatably installed in the first water inlet pipe 320. The conveying paddle 321 is transmission-connected to the output end of the motor 330 for forming a circulation inside the water propulsion device below. The two ends of the connecting piece 340 are respectively connected to the sealing cylinder 310 and the output end of the motor 330 for transmitting power.

[0037] The aeration and pollution-purification device for water environment restoration of the present embodiment is put into the water body, and the buoyancy of the float 110 is adjusted as needed to adjust the depth of the device. The motor 330 is started to drive the conveying paddle 321 to rotate, and the water at the bottom is pumped into the connecting tube 210. The sealing tube 310 drives the recovery tube 130 to make up and down reciprocating motion in the floating tube 120 through the power transmitted by the connecting piece 340 to change the water surface tension and collect the water on the surface of the water body into the recovery tube 130. After filtering, the pollutants in the water can be collected to facilitate subsequent treatment and recovery. At the same time, the sealing tube 310 moving up and down pumps the water in the connecting tube 210 into the floating tube 120 again through negative pressure and discharges it, so as to promote the uniform distribution of pollutants in the water body and avoid excessive local concentration. As the gas is input from the air pipe 230, aeration bubbles are formed, which collide with the water discharged from the floating tube 120, increase the contact area between the water body and the air, accelerate the process of oxygen transfer from the gas phase to the liquid phase, and accelerate the increase of the dissolved oxygen content in the water body, which is conducive to the survival of aquatic organisms and the improvement of water quality.

[0038] Each structure is described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 4 The connecting piece 340 includes a hollow shaft 341 and a ferrule 342. The hollow shaft 341 is rotatably connected to the connecting cylinder 210. The surface of one end of the hollow shaft 341 located outside the connecting cylinder 210 has a wave groove 301. The ferrule 342 is movably mounted on the hollow shaft 341 and has a pin 302 that matches the wave groove 301. The end surface of the hollow shaft 341 located at one end inside the connecting cylinder 210 is grid-shaped and has an extension portion 343. The extension portion 343 is transmission-connected to the output end of the motor 330.

[0040] Through the arrangement of the above structure, after the motor 330 is started, its output end transmits power to the hollow shaft 341 through the extension part 343. During the rotation process, the hollow shaft 341 converts the original rotational motion into the up and down reciprocating motion of the ferrule 342 installed therewith through the wave groove 301, so that the ferrule 342 drives the sealing tube 310 to reciprocate up and down in the float tube 120, and the lower water body transported to the float tube 120 is discharged from the top, thereby enhancing the turbulence.

[0041] In order to prevent the aeration gas from directly mixing with the water in the connecting tube 210, refer to Figure 1 and Figure 4 A shunt box 250 is fixedly installed in the connecting tube 210, the hollow shaft 341 and one end of the extension tube 220 located in the connecting tube 210 are both located in the shunt box 250, and the extension portion 343 passes through the shunt box 250 and is rotatably connected to the shunt box 250.

[0042] Through the arrangement of the above structure, high-pressure gas enters the diverter box 250 through the hollow shaft 341 and is evenly distributed through the extension tube 220, thereby achieving uniform dispersion of the gas in the water and improving the aeration effect.

[0043] Reference Figure 5 An array of air outlet holes 221 is provided on the upper surface of the extension tube 220 , a flexible tube 222 is fixedly mounted on the hole wall of the air outlet hole 221 , and an aeration hole 201 is provided on the flexible tube 222 .

[0044] Through the above-mentioned structure, efficient and uniform gas dispersion is achieved through the design of the extension tube 220 and the flexible tube 222. The aeration holes 201 on the flexible tube 222 ensure that the gas can be evenly released into the water, thereby improving the aeration effect. When not in operation, the flexible tube 222 can swing with the water body, thereby reducing the resistance of the water body to it, and reducing the impact force of the water body on the air pipe 230, thereby helping to protect the air pipe 230 from damage and avoid entanglement with obstacles in the water body.

[0045] Reference Figure 1 A hollow frame 140 is fixedly installed in the floating cylinder 120 , and the hollow frame 140 is filled with microbial carriers. One end of the second water inlet pipe 240 away from the connecting cylinder 210 passes through the hollow frame 140 and is higher than the surface of the hollow frame 140 .

[0046] Through the arrangement of the above structure, the microbial carriers filled in the hollow frame 140 provide a growth environment for the microorganisms, and contribute to the natural purification process of the water body after contacting with the water body.

[0047] Reference Figure 2 and Figure 3 The float 120 has a mounting groove 101, and a first through hole 102 communicating with the interior of the float 120 is opened on the inner side of the mounting groove 101. A sealing ring 150 is rotatably installed in the mounting groove 101, and a spoiler tube 160 is installed on the sealing ring 150. One end of the spoiler tube 160 passes through the first through hole 102 and communicates with the interior of the float 120.

[0048] Preferably, a first wedge block 311 is fixedly mounted on the sealing cylinder 310 , and a second wedge block 162 is fixedly mounted on one end of the spoiler tube 160 located in the floating cylinder 120 , and the inclined surfaces of the first wedge block 311 and the second wedge block 162 abut against each other.

[0049] Furthermore, a track groove 103 is formed on the bottom surface of the mounting groove 101 , a connecting pin 151 matching the track groove 103 is fixedly mounted on the sealing ring 150 , and a spring 170 is fixedly connected between the connecting pin 151 and the inner side surface of the track groove 103 .

[0050] Through the arrangement of the above structure, as the sealing cylinder 310 reciprocates up and down in the floating cylinder 120, the water in the connecting cylinder 210 is pumped into the floating cylinder 120 again and sprayed on the microbial carrier, thereby increasing the contact between the water body and the microbial carrier. When the inclined surfaces of the first wedge block 311 and the second wedge block 162 abut against each other, the sealing ring 150 and the spoiler tube 160 are driven to perform spoiler operations in the water body, thereby improving the efficiency of water environment restoration.

[0051] It should be noted that the spoiler tube 160 is provided with spoiler holes 161 at equal intervals for evenly discharging water.

[0052] Reference Figure 1 and Figure 2 The sealing cylinder 310 is fixedly connected to the recovery cylinder 130 and a storage chamber 303 is formed between the sealing cylinder 310 and the recovery cylinder 130. A water hole 131 is provided on the bottom surface of the recovery cylinder 130, and a one-way valve is installed in the water hole 131. A water outlet pipe 312 is installed on the cylinder wall of the sealing cylinder 310. A slide groove 121 adapted to the water outlet pipe 312 is provided on the cylinder wall of the floating cylinder 120, and a one-way valve is installed in both the water hole 131 and the water outlet pipe 312.

[0053] Furthermore, a vertical rod 141 is fixedly installed on the hollow frame 140 , and a pressing plate 142 is fixedly installed on the vertical rod 141 which penetrates the sealing cylinder 310 .

[0054] Through the arrangement of the above structure, since the hollow frame 140 and the extrusion plate 142 are in a constant position in the floating cylinder 120, the space between the bottom surface of the recovery cylinder 130 and the extrusion plate 142 increases and decreases intermittently during the up and down movement of the recovery cylinder 130, so the filtered water can be discharged from the outlet pipe 312.

[0055] In summary, the working principle of an aeration and pollution purification device for water environment restoration is as follows:

[0056] First, the device is placed in a body of water, and the buoyancy of the float 110 is adjusted as needed to adjust the depth of the device;

[0057] Next, the motor 330 is started to drive the delivery paddle 321 to rotate, and the water at the bottom is pumped into the connecting tube 210. At the same time, after the motor 330 is started, its output end transmits power to the hollow shaft 341 through the extension part 343. During the rotation process, the hollow shaft 341 converts the original rotational motion into the up and down reciprocating motion of the ferrule 342 installed therewith through the wave groove 301, and then the ferrule 342 drives the sealing tube 310 to do up and down reciprocating motion in the floating tube 120, changing the water surface tension and collecting the water on the surface of the water into the recovery tube 130. Filtration can collect pollutants in the water, which is convenient for subsequent treatment and recycling. At the same time, the sealing cylinder 310 that moves up and down uses negative pressure to pump the water in the connecting cylinder 210 to the floating cylinder 120 again and discharge it, so as to evenly distribute the pollutants in the water body and avoid excessive local concentration. As the gas is input from the air pipe 230 to form aeration bubbles, they collide with the water discharged from the floating cylinder 120, increase the contact area between the water body and the air, accelerate the process of oxygen transfer from the gas phase to the liquid phase, and speed up the increase of dissolved oxygen content in the water body, which is conducive to the survival of aquatic organisms and the improvement of water quality.

[0058] Then, the high-pressure gas enters the diversion box 250 through the hollow shaft 341, and is evenly distributed through the extension tube 220, and after contacting the water mixed with microorganisms, the efficiency of water environment restoration is improved;

[0059] Finally, since the hollow frame 140 and the extrusion plate 142 are in a constant position in the floating tube 120, the space between the bottom surface of the recovery tube 130 and the extrusion plate 142 increases and decreases intermittently during the up and down movement of the recovery tube 130, so that the filtered water can be discharged from the outlet pipe 312, leaving the garbage in the recovery tube 130.
