[0028] like Figure 1 to Figure 6 As shown, the present invention is a linear micro-nano aeration device for river water bodies, which is arranged in the river channel and includes a plurality of aeration components linearly and evenly arranged in the river channel, and the plurality of aeration components are evenly distributed along the length direction of the river channel until the entire river channel is covered. Specifically, the aeration component includes a lifting installation structure, and the lifting installation structure includes four fixed columns 5 distributed in a rectangular shape on the edges of the river banks 25 on both sides, one end of the fixed column 5 is plugged and fixed on the riverbed of the river channel near the river bank 25, and two fixed columns 5 in the width direction of the river channel are provided with mounting plates 6, and both ends of the mounting plates 6 are slidably connected to the two fixed columns 5, and the other end of the fixed column 5 is provided with a fixing ear 14, and the middle part of the fixing ear 14 is fixedly connected to the fixing column 5, and the ends of the mounting plate 6 are symmetrically provided with lifting ears 13, and one end of the lifting ear 13 It is fixed on the side of the mounting plate 6, and a lifting rope 15 is symmetrically arranged between the lifting ear 13 and the fixing ear 14, one end of the lifting rope 15 is fixed on the lifting ear 13, and the other end of the lifting rope 15 is connected to the fixing ear 14. A plurality of evenly distributed clamping blocks 8 (the aeration tube 3 can be fixed by components such as clamps) are arranged on the mounting plate 6, and a plurality of aeration tubes 3 are arranged on the clamping blocks 8. The ends of adjacent aeration tubes 3 are connected in series through a hose 4, and an input pipe 2 is arranged on the end of the outermost aeration tube 3, one end of the input pipe 2 is connected to the aeration tube 3, and the other end of the input pipe 2 is connected to the output end of the micro-nano bubble generator 1 arranged on the river bank 25, and a plurality of evenly distributed vertical pipes 16 are arranged in the length direction of the aeration tube 3, one end of the vertical pipe 16 is connected to the inside of the aeration tube 3, and the other end of the vertical pipe 16 is connected to the liquid in the river channel.

[0029] It should be noted in advance that the micro-nano bubble generator 1 is a prior art, which mainly relies on the interaction between high-pressure gas and liquid. When the high-pressure gas enters the liquid through a specific device, the interaction between the gas molecules and the liquid molecules will form tiny bubbles in the liquid. These bubbles will undergo compression, expansion and other processes during the formation process, thereby refining the size of the bubbles in an implementable manner. The core component of the micro-nano bubble generator 1 is a precise gas injection system, which can stably inject high-pressure gas into the liquid with a tiny flow rate. During the injection process, the gas molecules will collide and diffuse with the liquid molecules to form initial bubble nuclei. With the continuous injection of gas, these bubble nuclei will gradually grow up to form tiny bubbles. The existence time of micro-nano bubbles in the liquid is relatively long, which gives them more opportunities to interact with the surrounding substances, thereby achieving the purification of the water body.

[0030] Therefore, the working principle of this technical solution is:

[0031] Before installation, four fixing columns 5 are fixed on the riverbed at the edge of the river bank 25 in a rectangular shape, and then the installation plate 6 is lifted to the top of the fixing columns 5 by controlling the length of the lifting rope 15. At this time, the installation plate 6 is located above the liquid surface of the river channel. Then, the construction personnel lift the aeration pipe 3 so that the two ends of the aeration pipe 3 are respectively placed and fixed on the clamping block 8 until the installation of the aeration pipes 3 is completed. After the installation is completed, the ends of the aeration pipes 3 are connected in series through the hose 4, and then one end of the aeration pipe 3 is connected to the micro-nano bubble generator 1 through the input pipe 2. Finally, it is only necessary to control the length of the lifting rope 15 to sink all the components such as the installed aeration pipe 3 into the specified depth position in the river channel to perform aeration operation on the water body in the river channel.

[0032] The advantages of this arrangement are that, firstly, the installation plate 6 and other components are lifted above the river surface for installation of the aeration pipe 3 and other components, which can avoid the workers diving or installing the aeration pipe 3 on the riverbed, greatly simplifying the installation steps of the aeration assembly; secondly, adjacent aeration pipes 3 are connected by hoses 4 instead of being arranged as a whole, which is convenient for reducing the weight of the aeration pipe 3 during a single installation, so that the aeration pipe 3 can be installed by hoisting or transporting by boat; finally, after the structure of the aeration assembly is installed, most of the components sink into the water in the river channel, which will have a visual impact on the environment.

[0033] In one feasible manner, a slide groove 7 is provided in the length direction of the mounting plate 6, and a slider 9 is provided in the slide groove 7. One end of the slider 9 is fixedly connected to the bottom surface of the clamping block 8, that is, the slider 9 is slidably connected to the mounting plate 6 at this time, and winding posts 10 are provided at both ends of the mounting plate 6. An adjusting rope 11 is provided on the winding posts 10, and both ends of the adjusting rope 11 are respectively wound around the winding posts 10. The adjusting rope 11 passes through the middle part of the clamping block 8, and the clamping block 8 is slidably connected to the adjusting rope 11. Limiting rings 12 are provided on the connecting ropes on both sides of the clamping block 8. The limiting rings 12 are detachably connected to the adjusting rope 11, and the limiting rings 12 are used to limit the position of the clamping block 8 on the adjusting rope 11.

[0034] The working principle of this scheme is:

[0035] When the aeration pipe 3 is installed, the adjusting rope 11 on one side of the river bank 25 can be pulled to make several clamping blocks 8 slide under the pulling action and move closer to the river bank 25 on that side, that is, the clamping blocks 8 close to the river bank 25 can be arranged on the clamping blocks 8 by manually placing and installing the aeration pipe 3, without the need for long-distance lifting operations through lifting equipment, etc. (if the river surface is wide, the clamping blocks 8 are not gathered together, the lifting equipment needs to be lifted over a long distance, and the small boat transportation also needs to go back and forth many times, and the installation efficiency is low). When the aeration pipe 3 is installed, it is only necessary to pull the adjusting rope 11 on the other side of the river bank 25 to drive several sliders 9 to reset, thereby driving several aeration pipes 3 to be evenly distributed, thereby greatly improving the installation efficiency.

[0036] At the same time, the setting of the limiting ring 12 can limit the position by manually sliding the position of the slider 9 on the adjustment rope 11, and then locking the limiting ring 12 (the length of the adjustment rope 11 on the mounting plate 6 is fixed, that is, after the position is adjusted, the position of the clamping block 8 relative to the mounting plate 6 is fixed after the adjustment rope 11 is straightened), so as to adjust the distance between adjacent aeration pipes 3, that is, change the position of the aeration pipe 3 sunk into the river channel, which can be adjusted according to actual conditions.

[0037] In one practicable manner, the fixed column 5 is retractable, and the retractable setting can completely retract the liquid surface to the bottom, further reducing the impact on the environment.

[0038] In an operative manner, a micro-nano bubble discharge structure is provided on the other end of the vertical pipe 16, and the micro-nano bubble discharge structure includes a rotating joint 17, which is connected to the end of the vertical pipe 16, and a square tube 18 is provided on the output end of the rotating joint 17, one end of the square tube 18 is connected to the rotating joint 17, and the other end of the square tube 18 is closed, and a plurality of discharge pipes 19 are provided on one side of the square tube 18 perpendicular to the horizontal plane, one end of the discharge pipe 19 is connected to the interior of the square tube 18, and the other end of the discharge pipe 19 is provided There is a sloped surface, on which a cover plate 20 is arranged, and the cover plate 20 is arranged in close contact with the sloped surface. A connecting rod 21 is arranged on one end of the cover plate 20 pointing to the square tube 18, and one end of the connecting rod 21 is fixed to the side of the discharge pipe 19, and a rotating shaft 22 is arranged on the other end of the connecting rod 21. The other end of the cover plate 20 is rotatably arranged on the rotating shaft 22, and a plurality of springs 23 are arranged on the other end of the cover plate 20, and one end of the spring 23 is fixed to the side of the square tube 18, and the other end of the spring 23 is fixed to one end of the cover plate 20 on which the rotating shaft 22 is arranged.

[0039] The working principle of the above scheme is:

[0040] The micro-nano bubbles generated by the micro-nano bubble generator 1 are transported to the discharge pipe 19 through the aeration pipe 3, and then the cover plate 20 is impacted under the output pressure of the micro-nano bubbles to overcome the resistance of the spring 23 and open, thereby releasing the micro-nano bubbles into the river channel to improve the water body of the river channel. When the input of the micro-nano bubbles stops, the cover plate 20 is reset under the action of the spring 23, thereby closing the port of the discharge pipe 19 to prevent the port from being blocked by silt or impurities in the river channel. At the same time, the square tube 18 is installed on the riser 16 through a rotary joint, and then when the micro-nano bubbles containing pressure are discharged from the discharge pipe 19, they will push the square tube 18 to rotate, thereby realizing the rotary supply of micro-nano bubbles. The advantage of this is that the rotary supply of micro-nano bubbles can cover a larger water area and simplify the structure of the aeration device, that is, a larger aeration coverage area can be achieved without dense installation. At the same time, the pressure trend of the micro-nano bubbles is used to rotate the square tube 18, so that the underwater rotation does not need to be controlled by electronic components. While further simplifying the structure, it can also avoid the problem that the electronic components are located underwater, the installation is complicated, and they are easily damaged by immersion.

[0041] In one feasible manner, a cutting blade 24 is provided on a side surface of the square tube 18 opposite to the discharge pipe 19. The cutting blade 24 is detachably connected to the square tube 18, such as by a snap-on manner. At the same time, a pressure sensor is provided between the contact surface of the cutting blade 24 and the square tube 18. The pressure sensor is used to detect the pressure exerted by the cutting blade 24 on the square tube 18, and then determine the rotation state of the square tube 18.

[0042] It should be noted that when installing the device, it is necessary to clean the components of the waterweed in the river. After the device has been installed for a certain period of time, the waterweed in the river will slowly grow and extend, which may block the rotation of the square tube 18. When the square tube 18 rotates, the cutting blade 24 arranged thereon can cut the waterweed to a certain extent, thereby avoiding the problem of continuous growth of the waterweed. At the same time, it can also avoid the problem of the rotation of the square tube 18 being blocked, resulting in the aeration coverage area being affected.

[0043] When the cutting blade 24 is cutting the aquatic plants, the pressure it exerts on the square tube 18 will suddenly increase and then decrease. If the pressure sensor detects that the pressure increases at a certain place and does not change for a long time, it means that the rotation of the square tube 18 at this place is blocked, and the cutting blade 24 has been acting on the aquatic plants and cannot cut. If the rotation is blocked at multiple positions, it can be cleaned by lifting it with a lifting rope 15 and then put into the river for use. That is, the setting of the pressure sensor can monitor the rotation aeration state of the square tube 18 in the river channel and improve the aeration effect.

[0044] like Figure 7 As shown, in an operative manner, a plurality of push rods 26 are provided on the surface of the cutting blade 24 connected to the square tube 18, the number of the push rods 26 is the same as the number of the discharge pipes 19 provided on one square tube 18, one end of the push rod 26 is fixed to the cutting blade 24, the other end of the push rod 26 passes through the square tube 18 and is located between the cover plate 20 and the square tube 18, a support spring 27 is provided between the cutting blade 24 and the square tube 18, the support spring 27 is sleeved on the push rod 26, and both ends are fixedly connected to the square tube 18 and the cutting blade 24.

[0045] When the cutting blade 24 is blocked by the water plants and cannot cut through, the support spring 27 will be compressed under the thrust of the micro-nano bubbles, that is, the top rod 26 slides backward and abuts against one end of the cover plate 20, which will push the cover plate 20 to rotate, and then move toward the end of the discharge pipe 19, thereby reducing the discharge outlet at the end of the discharge pipe 19, thereby reducing the discharge flow rate, increasing the discharge pressure, and increasing the pressure that pushes the square tube 18 to rotate, thereby providing a greater thrust to the cutting blade 24, which helps to cut the water tank. After the cutting is completed, under the action of the support spring 27, the cutting blade 24 and the cover plate 20 are reset.

[0046] In one feasible manner, a rectangular mesh cover is provided on the outside of the aeration pipe 3, which covers the aeration pipe 3 and the components arranged thereon. A rectangular mesh cover is separately provided on the outside of each aeration pipe 3, and a plurality of water-permeable holes are provided on the rectangular mesh cover to facilitate the contact between the micro-nano bubbles and the river water. The purpose is to prevent organisms in the river, such as fish, from approaching components such as cutting blades and causing harm to aquatic organisms.

[0047] In one feasible manner, a lifting assembly is provided at the upper end of the fixed column 5, and the lifting assembly acts on the lifting rope 15 to lift and lower the mounting plate 6. The lifting assembly is preferably a hand-cranked lifting assembly, which is a prior art and will not be described in detail here.

[0048] In one feasible manner, a high-pressure water pump is further provided on the river bank 25 where the micro-nano bubble generator 1 exits, and a connector connected to the input pipe 2 is provided on the output end of the high-pressure water pump. When the rotation of the square tube 18 is obstructed, high-pressure water can be input into the discharge pipe 19 by connecting the end of the aeration tube 3 to the high-pressure water pump, thereby increasing the rotation thrust of the square tube 18, and enabling the cutting blade 24 to have a greater force to cut the aquatic plants, so that the square tube 18 is freed from the obstruction of the aquatic plants. The rotation restriction of the aquatic plants on the square tube 18 can be removed by means of the high-pressure water pump first, and after the high-pressure water pump has no effect, the lifting and cleaning operation can be performed.

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
