Description

Technical Field

[0001] This invention belongs to the field of aeration and algae control technology, specifically relating to an aeration device for algae control in water bodies. Background Technology

[0002] Currently, with the increase in industrial, agricultural, and domestic sewage discharge, large amounts of nutrients such as nitrogen and phosphorus continuously enter natural water bodies through urban drainage outlets and other pathways, easily leading to excessive algal growth and algal pollution phenomena such as algal blooms or red tides. This pollution problem is prevalent in various enclosed or slow-flowing water bodies, and even in important artificial waterways like the Pinglu Canal, which combine navigation, ecological, and landscape functions, there is a potential risk of algal proliferation due to limited water exchange. Explosive algal growth not only directly damages the aquatic landscape but also consumes dissolved oxygen, releases algal toxins, causes the death of aquatic organisms, and severely disrupts the ecological balance of the water body. To address this problem, aeration equipment has been widely used for algal control in eutrophic waters, inhibiting algal growth by oxygenating the water and promoting the decomposition of pollutants.

[0003] However, in practical use, it has been found that existing aeration equipment, during operation, converts some pollutants in the water into light suspended solids, which gradually accumulate to form scum. This scum accumulates on the surface for extended periods, forming a covering layer that severely blocks sunlight from penetrating underwater. Consequently, underwater photosynthetic organisms, which rely on sunlight, suffer from insufficient light, leading to stunted growth or even death. This further disrupts the original ecological balance of the water. Simultaneously, the large-scale decomposition of photosynthetic organisms consumes oxygen and releases additional pollutants, causing secondary deterioration of water quality. Therefore, how to avoid or reduce the accumulation of scum on the water surface after aeration, and prevent its negative impact on the underwater lighting environment and aquatic ecosystem, has become an urgent technical problem to be solved in current water management. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that current aeration equipment used for algae control in water bodies causes scum to accumulate on the water surface after aeration, which has a negative impact on the underwater lighting environment and aquatic ecosystem.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] An aeration device for controlling algae in aquatic waters includes a shell, an air pump fixedly installed inside the shell, an aeration head, and multiple buoyancy blocks disposed on the outside of the shell. The shell contains a battery and a controller electrically connected to the air pump. A fixing column is fixedly installed at the lower end of the shell, and the aeration head is fixedly installed at the lower end of the fixing column. An air supply pipe is provided between the air pump's outlet and the aeration head. A grid is provided at the upper end of the shell, and an air inlet pipe is provided at the air pump's inlet, the end of which is connected to the grid. Adjacent buoyancy blocks are connected to each other by connecting ropes. A pull rope is provided on the shell, the end of which is connected to a floating seat. An enclosure mechanism is provided between the shell and the floating seat to frame the aerated water area and retract it after aeration.

[0007] Further defining the enclosure mechanism, it includes a connecting pipe fixedly inserted into the housing, an enclosure tube fixedly connected to the end of the connecting pipe, and a pressure relief valve installed on the connecting pipe. A connecting seat is fixedly installed at the output end of the air pump. The connecting seat has two output ports and a solenoid valve that can close the two output ports. One end of the air supply pipe and the connecting pipe are fixedly connected to the two output ports respectively. The air supply pipe passes through the housing and the fixed column and communicates with the aeration end. A winding mechanism is provided on the floating seat to wind up the enclosure tube. A reversing groove is provided on the floating seat, and the end of the enclosure tube passes through the reversing groove and connects to the winding mechanism. With this structural design, when the air pump is working, the enclosure tube inflates and expands, which can gather and collect the scum in the aeration area, preventing the scum from spreading and accumulating on the water surface.

[0008] Furthermore, a suction pump is installed inside the housing. The suction pump has an inlet pipe and an outlet pipe fixedly installed at its inlet and outlet ends, respectively. The end of the suction pipe is connected to a connecting pipe, and the outlet pipe is connected to the grid. This structural design allows the suction pump to accelerate the venting and collapse process of the surrounding pipe, significantly reducing its volume and rigidity. This greatly reduces the winding resistance of the winding mechanism, making the winding action faster, smoother, and more efficient, thus improving the smoothness and efficiency of the entire scum collection process.

[0009] Further specifying, the winding mechanism includes a winding roller, a motor, and a belt. Two support pillars are fixedly mounted on the floating base. The winding roller is rotatably mounted between the two support pillars. The motor is fixedly mounted on the upper end of the floating base. A first friction wheel and a second friction wheel are respectively provided on the output shaft of the motor and the rotating shaft of the winding roller. The belt is sleeved on the first and second friction wheels. The support pillars and the floating base have clearance grooves for the belt to pass through. The two support pillars are equipped with extrusion components to assist the winding roller in winding the surrounding tube. This structural design, with the extrusion components, applies continuous radial pressure to the surrounding tube wound on the winding roller, ensuring that the surrounding tube is tightly and smoothly wound layer by layer. This effectively prevents loosening, slippage, or misalignment during the winding process, guaranteeing winding quality and reliability.

[0010] Further specifying, the extrusion component includes two fixed arms respectively fixedly mounted on two supports, a pressure roller disposed between the two fixed arms, and an adapter seat. Each fixed arm has a movable groove, and the adapter seat is movably mounted within the movable groove. An insert rod is fixedly mounted on the adapter seat, penetrating the fixed arm. A compression spring is fitted onto the end of the insert rod furthest from the support at the adapter seat and movable groove. The pressure roller has adapter posts at both ends, and the adapter posts are rotatably connected to the adapter seat. This structural design, through the elastic force provided by the compression springs, ensures that the pressure roller always adaptively presses against the already wound outer layer of the tube on the take-up roller.

[0011] Furthermore, a mounting rod is fixedly installed on the fixed arm, and a positioning plate is fixedly installed at the end of the mounting rod. A strip-shaped opening is formed on the positioning plate, through which the surrounding tube passes. This structural design provides a fixed and precise guide for the entry and exit path of the surrounding tube, through the positioning plate and its strip-shaped opening.

[0012] Furthermore, the positioning plate has a mounting groove communicating with the strip-shaped opening. An electric push rod is fixedly installed in the mounting groove, and a pressure strip is fixedly installed at the end of the electric push rod. This structural design allows the pressure strip to be driven by the electric push rod, thus pressing the enclosure tube to adjust the overall length of the enclosure tube and thereby adjust the area of ​​the enclosed region.

[0013] Furthermore, the outer casing is covered with a sponge layer. This structural design, with the sponge layer covering the casing, primarily utilizes the sponge's strong water absorption properties to absorb a large amount of water during operation, significantly increasing the overall weight of the casing in the water. This weight increase effectively balances the buoyancy of the casing after inflation, preventing it from tilting, floating, or becoming unstable in the water, ensuring it can stably define the water boundary in a preset upright or circular posture.

[0014] Furthermore, the floating seat is equipped with multiple rollers that rotatably contact the surrounding tube within the reversing groove. This structural design, with multiple rollers within the reversing groove, transforms the sliding friction between the surrounding tube and the groove wall into rolling friction. This significantly reduces the movement resistance of the surrounding tube at the reversing point, reduces wear on the surface of the surrounding tube, makes the deployment and retraction process smoother and less strenuous, and helps extend the service life of the surrounding tube.

[0015] The invention employing the above technical solution has the following advantages:

[0016] This invention, before aeration, expands the enclosure pipe by inflating it, which can accurately define and isolate the target water area to be treated, confining the scum generated thereafter within the enclosure area. After aeration, the enclosure pipe is retracted by a winding mechanism, which can simultaneously push and gather the scum gathered in the area to the vicinity of the floating seat, realizing the active collection and concentration of scum, preventing scum from spreading and accumulating on the water surface over a large area, and effectively protecting the underwater light environment.

The enclosure pipe 71 is covered with a sponge layer 711. When the enclosure pipe 71 is inflated, the sponge layer 711 absorbs water, increasing the overall mass of the enclosure pipe 71 and preventing the enclosure pipe 71 from tilting during aeration. A connecting seat 21 is fixedly installed at the output end of the air pump 2. The connecting seat 21 is provided with two output ports and a solenoid valve that can close the two output ports. One end of the air supply pipe and the connecting pipe 7 are fixedly connected to two output ports respectively. The air supply pipe passes through the shell 1 and the fixed column and is connected to the aeration end 3. The floating seat 6 is provided with a winding mechanism 73 that can wind up the surrounding pipe 71. The floating seat 6 is provided with a reversing groove 61, which is an arc-shaped connecting groove. The end of the surrounding pipe 71 passes through the reversing groove 61 and connects with the winding mechanism 73. Multiple rollers that rotatably contact the surrounding pipe 71 are installed on the floating seat 6 in the reversing groove 61 to reduce the frictional resistance at the reversing point.

[0042] A suction pump 8 is installed inside the housing 1. The suction pump 8 has a suction pipe and an exhaust pipe fixedly installed at its inlet and outlet ends, respectively. The end of the suction pipe is connected to the connecting pipe 7, and the exhaust pipe is connected to the grille 11.

[0043] The winding mechanism 73 includes a winding roller 731, a motor 732, and a belt 733. Two support columns 62 are fixedly installed on the floating seat 6. The winding roller 731 is rotatably installed between the two support columns 62. The motor 732 is fixedly installed on the upper end of the floating seat 6. The output shaft of the motor 732 and the rotating shaft of the winding roller 731 are respectively provided with a first friction wheel and a second friction wheel. The belt 733 is sleeved on the first friction wheel and the second friction wheel. The support columns 62 and the floating seat 6 are provided with clearance grooves for the belt 733 to pass through. The two support columns 62 are provided with extrusion parts for the auxiliary winding roller 731 to wind the surrounding tube 71.

[0044] The extrusion component includes two fixed arms 621 respectively fixedly mounted on two support columns 62, a pressure roller 622 disposed between the two fixed arms 621, and an adapter seat 623. The fixed arms 621 are provided with movable grooves, and the adapter seat 623 is movably mounted in the movable grooves. An insert rod 624 is fixedly mounted on the adapter seat 623, and the insert rod 624 passes through the fixed arms 621. A compression spring 625 is sleeved on the insert rod 624 at the end of the adapter seat 623 and the movable groove away from the support column 62. The pressure roller 622 is provided with adapter posts at both ends, and the adapter posts are rotatably connected to the adapter seat 623.

[0045] A mounting rod 6211 is fixedly installed on the fixed arm 621. A positioning plate 6212 is fixedly installed at the end of the mounting rod 6211. A strip opening 6213 is opened on the positioning plate 6212, and the surrounding tube 71 passes through the strip opening 6213.

[0046] The positioning plate 6212 has an installation groove that communicates with the strip opening 6213. An electric push rod is fixedly installed in the installation groove. A pressure strip 6214 is fixedly installed at the end of the electric push rod. When the surrounding tube 71 is inflated, the electric push rod and the pressure strip 6214 can press the surrounding tube 71 to adjust the overall length of the surrounding tube 71, thereby adjusting the area of ​​the enclosed area. After collection is completed, the electric push rod drives the pressure strip 6214 to press the end of the surrounding tube 71 to prevent the surrounding tube 71 from loosening.

[0047] The method of using this invention is as follows:

[0048] The equipment is deployed to the water area to be treated. The equipment is started by the controller. First, the solenoid valve on the connecting seat 21 is controlled so that all the gas output by the air pump 2 flows to the connecting pipe 7. The gas fills the enclosure pipe 71, which gradually expands and extends in the water. When it expands, the enclosure pipe 71 pushes the floating seat 6 away from the shell 1. The enclosure pipe wound on the winding roller 731 will be released outward under the action of force, and finally form a closed or preset-shaped fence to accurately frame and isolate the water area to be treated. During this process, the sponge layer covering the enclosure pipe 71 quickly absorbs water, increases the overall counterweight, and ensures that the enclosure pipe maintains a stable and vertical enclosure posture in the water to prevent tilting. The pressure relief valve 72 can ensure that the internal pressure is within a safe range.

[0049] Once the enclosure pipe 71 is fully extended and stabilized, the controller issues a command to switch the state of the solenoid valve. At this time, the air passage to the connecting pipe 7 is completely closed, while the air passage to the aeration end 3 is opened. All the gas generated by the air pump 2 is transported to the aeration end 3 through the air delivery pipe and efficiently and centrally aerated and oxygenated in the water area enclosed by the enclosure to inhibit algae growth and decompose pollutants.

[0050] After the aeration operation is completed, the pollutants floating in the water are confined within the enclosure area to form scum. The controller starts the winding program, and the motor 732 of the suction pump 8 and the winding mechanism 73 starts. The suction pump 8 continuously and actively extracts the remaining gas in the enclosure tube 71 through the connecting pipe 7, causing it to quickly collapse and soften. At the same time, the motor 732 drives the winding roller 731 to rotate, smoothly winding up the initially vented and flat enclosure tube 71. With the assistance of the extrusion component, the enclosure tube 71 is tightly wound, the water absorbed in the sponge layer is squeezed out, and the remaining air in the enclosure tube 71 is accelerated out. As the enclosure tube 71 is wound up, the water surface area originally enclosed by it continues to shrink, and all the floating scum is simultaneously pushed and gathered into a very small area around the floating seat 6.

[0051] After the scum is collected, it can be easily removed in one go by manual labor or supporting equipment. After collection, the pressure bar 6214 can be driven by an electric push rod to press the end of the pipe to prevent loosening. The equipment can then be transferred to the next area, and the above steps can be repeated to start a new treatment cycle.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
