Description

Technical Field

[0001] This invention relates to the technical field of water conservancy and hydropower engineering structures, specifically to a dam anti-icing and anti-freezing device. Background Technology

[0002] As is well known, in frigid regions, the temperature difference between day and night is large and cold waves are frequent. Due to the low water surface temperature, ice will form. The ice thrust and compression force generated by the ice will damage the dam body, thereby threatening the integrity and durability of the hydraulic structure. Therefore, in low temperatures, it is necessary to prevent the water surface from freezing, thereby reducing the impact of low temperature water surface freezing on the dam body.

[0003] For example, the invention disclosed in announcement number CN114108542A, dated March 1, 2022, entitled "Anti-icing Device and Method for Water Conservancy Facilities," belongs to the field of water conservancy and hydropower facility protection technology. The anti-icing device is a microbubble method device installed underwater to prevent damage from ice cover static pressure and flowing ice to hydraulic facilities and structures, especially dams (sluices), reservoirs, rivers, hydropower stations, and other water conservancy projects. The anti-icing device includes a gas diffuser with mushroom-shaped aeration heads and base connectors; a manually controlled conveying system consisting of pipes, ball valves, and manifolds; an automatic control system consisting of temperature sensors, pressure sensors, jet cycle flow sensors, water level sensors, proportional valves, and a video monitor; a remote monitoring system; and an air supply system consisting of a blower, screw compressor, air tank, filter, and refrigerated dryer. This invention has changed the anti-icing device and method, with good real-time performance, low failure rate, strong practicality, and good anti-icing effect; its production process and installation are simple.

[0004] The shortcomings of existing technologies are that most existing anti-icing devices are fixedly installed on the dam body, and the nozzles of the bubble generators are fixedly connected to the air outlet pipes. There are certain foreign objects in the water, and pollutants in the water often clog the bubble generators, requiring the bubble generators to be removed for cleaning, which is quite troublesome. Summary of the Invention

[0005] The purpose of this invention is to provide a dam anti-icing and anti-freezing device to solve the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-icing and anti-freezing device for dams includes an air pump, the output end of which is connected to an air inlet pipe that is suspended in water. The device also includes a bubble unit, which includes a driven pipe. Multiple driven pipes are evenly arranged along the axial direction of the air inlet pipe in a rotatable manner. Multiple exhaust pipes are evenly arranged along the axial direction of each driven pipe. Each exhaust pipe has a bubble pipe at both ends, and the same exhaust pipe and the bubble pipes at both ends are connected to form a Z-shaped pipe fitting.

[0008] As described above, the output end of the air pump is connected to the air inlet pipe through a bellows, and a positioning ring is connected to the bellows, and the positioning ring is rotatably connected to the air inlet pipe.

[0009] As described above, the bubble unit also includes positioning tubes. Multiple positioning tubes are evenly arranged on both sides of the outer wall of the air inlet pipe along its axial direction. The positioning tubes evenly arranged on both sides of the air inlet pipe are staggered with each other. A spherical groove is provided at the end of the positioning tube. A spherical component is movably installed in each of the spherical grooves. Each of the spherical components is connected to a driven tube.

[0010] As described above, the top end of the air intake pipe is uniformly provided with multiple floating ropes along its axial direction, and each of the floating ropes is connected to a floating component so that the air intake pipe is suspended in the water.

[0011] As described above, a plurality of counterweight ropes are evenly arranged at the bottom end of the air intake pipe along its axial direction, and each counterweight rope is connected to a counterweight box.

[0012] As mentioned above, each of the aforementioned counterweight boxes contains a plurality of counterweight blocks evenly arranged therein.

[0013] As mentioned above, an active component is provided at the end of the air intake pipe.

[0014] As described above, the output end of the active component is connected to a connecting rod, one end of the connecting rod is connected to a first arc-shaped baffle, and the other end of the connecting rod is connected to a second arc-shaped baffle. The first arc-shaped baffle and the second arc-shaped baffle provide a sliding seal for the positioning tube.

[0015] As described above, the first arc-shaped baffle and the second arc-shaped baffle are evenly provided with a plurality of air outlets. The first arc-shaped baffle and the second arc-shaped baffle are provided with two adjacent air outlets from the ends as a group, and each group of air outlets is connected and cooperates with its corresponding positioning tube.

[0016] As mentioned above, the spacing between a group of air outlets on the first arc-shaped baffle is greater than the spacing between a group of air outlets on the second arc-shaped baffle.

[0017] The beneficial effects of this invention are as follows: When anti-icing treatment of the water surface is required, the air inlet pipe is placed in the water body, and the air pump is started to deliver the air through the corrugated pipe and the air inlet pipe to the driven pipe. The gas in the driven pipe is discharged from the exhaust pipe and the bubble tube. Since the end of the bubble tube is provided with an exhaust hole, microbubbles are generated when the gas is discharged from the exhaust hole of the bubble tube. The microbubbles discharged from the exhaust hole of the bubble tube can prevent the water surface from freezing. The gas in the bubble tube is discharged into the water body. Under the driving force of the gas in the water body, the bubble tube and the exhaust pipe can rotate. The exhaust pipe and the bubble tube drive the driven pipe to rotate on the air inlet pipe. When the exhaust pipe and the bubble tube rotate, the risk of bubble tube blockage can be greatly reduced. Even if a few foreign objects block the bubble tube when it rotates, the bubble tube can be thrown out of the bubble tube when it rotates, so that the bubble tube will not be blocked, thus improving the stability of microbubble generation by the bubble tube.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 14 The present invention will now be described in further detail.

[0036] One embodiment of the present invention relates to a dam anti-icing and anti-freezing device, including an air pump, the output end of which is connected to an air inlet pipe 2, the air inlet pipe 2 being suspended in water, and an air bubble unit, the air bubble unit including a driven pipe 3, a plurality of driven pipes 3 being uniformly arranged along the axial direction of the air inlet pipe 2 in a rotatable manner, a plurality of exhaust pipes 4 being uniformly arranged along the axial direction of each driven pipe 3, and an air bubble pipe 5 being provided at both ends of each exhaust pipe 4, and the same exhaust pipe 4 and the air bubble pipes 5 at both ends are connected to form a Z-shaped pipe fitting.

[0037] Specifically, the air pump is used to force gas into the air inlet pipe 2. The output end of the air pump is connected to a movable pipe (such as a corrugated pipe 1) so that the air inlet pipe 2, which is suspended in the water, can move within a certain range. The corrugated pipe 1 is a flexible hose that can extend, retract, and rotate slightly. A positioning ring 6 is connected to the corrugated pipe 1. The positioning ring 6 is rotatably connected to the air inlet pipe 2, so that the air inlet pipe 2 can rotate on the positioning ring 6. The air inlet pipe 2 is preferably an "L"-shaped fitting. The vertical section of the air inlet pipe 2 is rotatably connected to the positioning ring 6. Multiple driven pipes 3 are evenly arranged along the axial direction of the horizontal section of the air inlet pipe 2 in a rotatable manner. Each driven pipe 3 is perpendicular to the horizontal section of the air inlet pipe 2. The intake pipe 2 is vertically arranged with each driven pipe 3 perpendicular to the vertical section of the intake pipe 2. Multiple exhaust pipes 4 are evenly arranged along the axial direction of each driven pipe 3, each exhaust pipe 4 perpendicular to its corresponding driven pipe 3. The middle of each exhaust pipe 4 is connected to the driven pipe 3, and each exhaust pipe 4 has a bubble tube 5 at both ends. The same exhaust pipe 4 is connected to the bubble tubes 5 at both ends to form a Z-shaped fitting. The ends of the bubble tubes 5 have exhaust holes. When anti-icing treatment is required on the water surface, the worker places the intake pipe 2 into the water and arranges it as a suspension. Through the expansion and contraction of the corrugated pipe 1, the vertical section of the intake pipe 2 is made perpendicular to the water surface. The air pump is then started to pass the air through the corrugated pipe 1 and the intake pipe. 2. The gas is delivered to the driven pipe 3. The gas in the driven pipe 3 is discharged from the exhaust pipe 4 and the bubble tube 5. Since the end of the bubble tube 5 is provided with an exhaust hole, microbubbles are generated when the gas is discharged from the exhaust hole of the bubble tube 5. The microbubbles discharged from the exhaust hole of the bubble tube 5 can prevent the water surface from freezing (the energy of the microbubble bursting can prevent the accumulation of ice crystals in the water, effectively preventing the formation of ice layer). The gas is discharged from the exhaust pipe 4 and the bubble tube 5. Since the same exhaust pipe 4 and the bubble tubes 5 at both ends are connected to form a Z-shaped pipe, the gas flows from the middle of the exhaust pipe 4 to the bubble tubes 5 at both ends and is discharged from the bubble tubes 5. The gas in the bubble tube 5 is discharged into the water body. The bubble tube 5 and the exhaust pipe 4 are in The gas propulsion within the water body causes the bubble tube 5 and the exhaust pipe 4 to rotate. This allows the exhaust pipe 4 and the bubble tube 5 to drive the driven pipe 3 to rotate on the air inlet pipe 2, enabling the microbubbles discharged from the bubble tube 5 to move in multiple directions. This expands the range of movement of the microbubbles, increasing the area of ​​the bubbles that can prevent ice formation on the water surface. Furthermore, since the exhaust pipe 4 and the bubble tube 5 do not adhere to the bottom wall of the dam during rotation, the risk of blockage in the bubble tube 5 is greatly reduced. Even if a few foreign objects block the bubble tube 5 during rotation, the rotation can dislodge the blockage, preventing blockage and improving the stability of microbubble generation in the bubble tube 5.

[0038] The shortcomings of existing technologies are that most existing anti-icing devices are fixedly installed on the dam body, and the nozzles of the bubble generators are fixedly connected to the air outlet pipes. There are certain foreign objects in the water, and pollutants in the water often clog the bubble generators, requiring the bubble generators to be removed for cleaning, which is quite troublesome.

[0039] The beneficial effects of this embodiment are as follows: When anti-icing treatment of the water surface is required, the air inlet pipe 2 is placed in the water body, and the air pump is started to deliver the air through the corrugated pipe 1 and the air inlet pipe 2 to the driven pipe 3. The gas in the driven pipe 3 is discharged from the exhaust pipe 4 and the bubble tube 5. Since the end of the bubble tube 5 is provided with an exhaust hole, microbubbles are generated when the gas is discharged from the exhaust hole of the bubble tube 5. The microbubbles discharged from the exhaust hole of the bubble tube 5 can prevent the water surface from freezing. The gas in the bubble tube 5 is discharged into the water body. Under the driving force of the gas in the water body, the bubble tube 5 and the exhaust pipe 4 can rotate. The exhaust pipe 4 and the bubble tube 5 drive the driven pipe 3 to rotate on the air inlet pipe 2. When the exhaust pipe 4 and the bubble tube 5 rotate, the risk of the bubble tube 5 being blocked can be greatly reduced. Even if a few foreign objects block the bubble tube 5 when it rotates, the bubble tube 5 can be thrown out of the bubble tube 5 when it rotates, so that the bubble tube 5 will not be blocked, thus improving the stability of the microbubble generation of the bubble tube 5.

[0040] Preferably, the bubble unit further includes positioning tubes 7. Multiple positioning tubes 7 are evenly arranged on both sides of the outer wall of the air inlet pipe 2 along its axial direction. The positioning tubes 7 evenly arranged on both sides of the air inlet pipe 2 are staggered with each other. The end of the positioning tube 7 is provided with a spherical groove. A spherical component 8 is movably installed in each of the spherical grooves. Each of the spherical components 8 is connected to a driven pipe 3 to transport the gas in the air inlet pipe 2 to the driven pipe 3.

[0041] Specifically, since the positioning tube 7 and the driven tube 3 are movably connected through a spherical component 8 and a spherical groove on the positioning tube 7, microbubbles are generated when gas is discharged from the exhaust port of the bubble tube 5. Because the same exhaust pipe 4 and the bubble tubes 5 at both ends are connected to form a Z-shaped pipe, gas flows from the middle of the exhaust pipe 4 to the bubble tubes 5 at both ends. The gas in the bubble tubes 5 is discharged into the water body. Under the driving force of the gas in the water body, the bubble tubes 5 and the exhaust pipe 4 can rotate, causing the exhaust pipe 4 and the bubble tube 5 to drive the driven tube 3 to rotate on the air inlet pipe 2. Because the positioning tube 7 and the driven tube 3 are movably connected through a spherical component 8 and a spherical groove on the positioning tube 7, microbubbles are generated when gas is discharged from the exhaust port of the bubble tube 5. The moving connection allows the driven pipe 3 to swing on the intake pipe 2, which in turn drives the exhaust pipe 4 and the bubble tube 5 to swing. This allows the microbubbles discharged from the bubble tube 5 to move in multiple directions, resulting in a wider range of movement for the microbubbles and increasing the area of ​​the bubbles that can reach the anti-icing water surface. Furthermore, the swinging of the exhaust pipe 4 and the bubble tube 5 greatly reduces the risk of blockage in the bubble tube 5. Even if a few foreign objects block the bubble tube 5 during its swing, the swinging motion can dislodge the blockage, preventing blockage and improving the stability of the microbubbles generated by the bubble tube 5.

[0042] Preferably, a plurality of floating ropes 9 are evenly arranged at the top end of the air intake pipe 2 along its axial direction, and a floating element 10 is connected to each of the floating ropes 9 so that the air intake pipe 2 is suspended in the water; a plurality of counterweight ropes 11 are evenly arranged at the bottom end of the air intake pipe 2 along its axial direction, and a counterweight box 12 is connected to each of the counterweight ropes 11; a plurality of counterweight blocks 13 are evenly arranged in each of the counterweight boxes 12.

[0043] Specifically, before placing the air intake pipe 2 into the water, a counterweight block 13 of appropriate weight is placed in the counterweight box 12. The counterweight box 12 is then placed into the water. The counterweight box 12 and the counterweight block 13, via the counterweight rope 11, drive the air intake pipe 2 towards the bottom of the water. Simultaneously, the float 10 (which can float on the water surface, providing buoyancy to the float rope 9) floats on the surface, providing buoyancy to the air intake pipe 2 via the float rope 9. This allows the air intake pipe 2 to suspend in the water. Furthermore, when the exhaust pipe 4 and the bubble tube 5 swing, they can drive the air intake pipe 2 into the water. The floating motion allows the air intake pipe 2 to move to a suitable anti-icing position. The lengths of the counterweight rope 11 and the floating rope 9 can be adjusted. When the length of the counterweight rope 11 is adjusted, the depth of the counterweight box 12 in the water can be adjusted accordingly. When the length of the floating rope 9 is adjusted, the depth of the air intake pipe 2 in the water can be adjusted accordingly. This adjustment of the depth of the air intake pipe 2 in the water causes the depth of the microbubbles generated in the exhaust pipe 4 and the bubble pipe 5 to change, so that the microbubbles generated in the exhaust pipe 4 and the bubble pipe 5 can provide stable anti-icing treatment for the water.

[0044] In another embodiment of the present invention, an active member 14 is provided at the end of the air intake pipe 2; a connecting rod 15 is connected to the output end of the active member 14, one end of the connecting rod 15 is connected to a first arc-shaped baffle 16, and the other end of the connecting rod 15 is connected to a second arc-shaped baffle 17. The first arc-shaped baffle 16 and the second arc-shaped baffle 17 are provided with a sliding seal for the positioning pipe 7; a plurality of air outlets 18 are evenly provided on the first arc-shaped baffle 16 and the second arc-shaped baffle 17, and two adjacent air outlets 18 are formed as a group from the end of the first arc-shaped baffle 16 and the second arc-shaped baffle 17. Each group of air outlets 18 is interconnected with its corresponding positioning pipe 7; the distance between a group of air outlets 18 on the first arc-shaped baffle 16 is greater than the distance between a group of air outlets 18 on the second arc-shaped baffle 17.

[0045] Specifically, the spacing between a group of air outlets 18 on the first arc-shaped baffle 16 is greater than the spacing between a group of air outlets 18 on the second arc-shaped baffle 17. That is, the spacing between a group of air outlets 18 on the first arc-shaped baffle 16 (i.e., two adjacent air outlets 18 connected to the same positioning tube 7) is greater than the spacing between a group of air outlets 18 on the second arc-shaped baffle 17 (i.e., two adjacent air outlets 18 connected to the same positioning tube 7). When one air outlet 18 at the end of each group of air outlets 18 on the first arc-shaped baffle 16 closest to the active member 14 is aligned with the positioning tube 7... When connected, one vent 18 at the end of each group of vents 18 on the second arc-shaped baffle 17 closest to the active member 14 is not connected to the positioning tube 7 (i.e., the second arc-shaped baffle 17 blocks the positioning tube 7); when one vent 18 at the end of each group of vents 18 on the second arc-shaped baffle 17 closest to the active member 14 is connected to the positioning tube 7, one vent 18 at the end of each group of vents 18 on the first arc-shaped baffle 16 closest to the active member 14 is not connected to the positioning tube 7 (i.e., the first arc-shaped baffle 16 blocks the positioning tube 7); when the first arc-shaped baffle 16 and the second arc-shaped baffle 17 are connected, one vent 18 at the end of each group of vents 18 on the first arc-shaped baffle 16 closest to the active member 14 is not connected to the positioning tube 7; when the first arc-shaped baffle 16 and the second arc-shaped baffle 17 are connected, one vent 18 at the end of each group of vents 18 on the first arc-shaped baffle 16 is connected to the positioning tube 7. When each set of air outlets 18 on the baffle 17 is connected to the positioning tube 7 at the end away from the active component 14, the gas delivery method in the corresponding air inlet pipe 2 is divided into three release methods, namely: (1) When the temperature in the water body is low, the air pump delivers a relatively large amount of gas. At this time, the positioning tubes 7 on both sides of the air inlet pipe 2 need to be ventilated at the same time, that is, the bubble tubes 5 on both sides of the air inlet pipe 2 need to generate microbubbles at the same time. At this time, the air outlets 18 on both sides of the air inlet pipe 2 need to be connected to the positioning tubes 7 to start the active component 14 (the active component 14 is the output end that can perform linear reciprocating motion). The device, preferably an electric push rod, drives the connecting rod 15 to move towards the end near the air inlet pipe 2. At this time, the active component 14 retracts, synchronously driving the first arc-shaped baffle 16 and the second arc-shaped baffle 17 to move via the connecting rod 15. This causes the air outlets 18 on the first and second arc-shaped baffles 16 and 17 to simultaneously connect with the positioning pipe 7, allowing the gas in the driven pipe 3 to be simultaneously discharged into each exhaust pipe 4 and the bubble tube 5. This enables the release of microbubbles in each bubble tube 5, allowing the microbubbles released in each bubble tube 5 to perform comprehensive anti-icing operations on the water (e.g., Figure 5(as shown); (2) When the temperature in the water body is relatively high, the air pump output is relatively small. At this time, only the positioning pipe 7 on one side of the air inlet pipe 2 needs to be ventilated to reduce the air pump output and perform certain energy-saving treatment on the air pump. When microbubbles need to be generated in the bubble tube 5 on one side of the air inlet pipe 2, the air outlet 18 on one side of the air inlet pipe 2 needs to be connected with the positioning pipe 7 to seal the positioning pipe 7 on the other side of the air inlet pipe 2. Start the active component 14 to drive the connecting rod 15 to move. That is, at this time, the active component 14 drives the first arc baffle 16 and the second arc baffle 17 to move simultaneously through the connecting rod 15, so that the air outlet 18 on the first arc baffle 16 is connected with the positioning pipe 7 on the same side, while the second arc baffle 17 seals the positioning pipe 7 on the same side, so that there is gas in the positioning pipe 7 on the side of the first arc baffle 16 in the air inlet pipe 2 for gas to be delivered. The gas in the positioning tube 7 is discharged from the driven tube 3 into the exhaust tube 4 and the bubble tube 5. The bubble tube 5 rotates in the water. Due to the rotation of the bubble tube 5 on the side of the air inlet tube 2, the air inlet tube 2 will rotate around the positioning ring 6. The rotation of the bubble tube 5 drives the air inlet tube 2 to rotate. The rotation of the bubble tube 5 in the water is equivalent to a "propeller". That is, the rotation of the bubble tube 5 in the water causes the side of the air inlet tube 2 to be powered by the rotation of the bubble tube 5, causing the air inlet tube 2 to rotate. The rotation of the air inlet tube 2 drives the driven tubes 3, the exhaust tube 4 and the bubble tube 5 to move synchronously. This increases the range of bubbles released in the exhaust tube 4 and the bubble tube 5, allowing the bubbles released in the exhaust tube 4 and the bubble tube 5 to perform anti-icing treatment on a larger water area. This not only saves energy but also increases the anti-icing area of ​​the water body (e.g., Figure 4(as shown); (3) When the air inlet pipe 2 rotates to a certain angle on one side of the first arc-shaped baffle 16, that is, when the air inlet pipe 2 no longer rotates under the pulling action of the counterweight box 12 and the counterweight rope 11, the active member 14 is activated to drive the connecting rod 15 to move. That is, at this time, the active member 14 drives the first arc-shaped baffle 16 and the second arc-shaped baffle 17 to move simultaneously through the connecting rod 15, so that the air outlet 18 on the second arc-shaped baffle 17 is connected to the positioning pipe 7 on the same side, and the first arc-shaped baffle 16 blocks the positioning pipe 7 on the same side, so that gas is transported in the positioning pipe 7 on one side of the second arc-shaped baffle 17 in the air inlet pipe 2, so that the gas in the positioning pipe 7 is discharged from the driven pipe 3 into the exhaust pipe 4 and the bubble pipe 5. The bubble pipe 5 rotates in the water body. Due to the rotation of the bubble pipe 5 on one side of the air inlet pipe 2, the air inlet pipe 2 will be positioned by the bubble pipe 5. Rotating around the center 6 causes the bubble tube 5 to rotate simultaneously with the air intake pipe 2. The rotation of the bubble tube 5 within the water acts like a "propeller," meaning that the rotation of the bubble tube 5 causes the air intake pipe 2 to rotate on one side, allowing it to return to its original position. This relieves the counterweight box 12 and counterweight rope 11 from tensioning the air intake pipe 2, allowing it to float. The rotation of the air intake pipe 2 also drives the synchronous movement of the driven pipes 3, exhaust pipe 4, and bubble tube 5, increasing the range of bubbles released from the exhaust pipe 4 and bubble tube 5. This allows the bubbles released from the exhaust pipe 4 and bubble tube 5 to provide anti-icing treatment over a larger water area, saving energy and increasing the anti-icing area. Furthermore, the air intake pipe 2 can rotate back to its position before the first arc-shaped baffle 16 allows air to pass through (e.g., ...). Figure 3 As shown); Both states (2) and (3) above can save energy and can rotate at a certain angle and return to their original position, increasing the area of ​​water body anti-icing.

[0046] In another embodiment of the present invention, a driving member 22 is provided at the end of the air intake pipe 2, and a sealing cylinder 23 is connected to the output end of the driving member 22. The sealing cylinder 23 is rotatably sealed on the inner wall of the air intake pipe 2. Multiple sets of exhaust holes 24 are uniformly arranged in the axial direction of the sealing cylinder 23. Each set of exhaust holes 24 consists of two exhaust holes 24. Each exhaust hole 24 is connected to its corresponding positioning pipe 7. The spacing between each set of exhaust holes 24 on two adjacent positioning pipes 7 is different. In the circumferential direction of the sealing cylinder 23, the spacing between the two exhaust holes 24 corresponding to one positioning pipe 7 is different from the spacing between the two exhaust holes 24 corresponding to the other adjacent positioning pipe 7. Moreover, one exhaust hole 24 of each set of exhaust holes 24 is symmetrical about the axis of the sealing cylinder 23, while the other exhaust hole 24 of each set of exhaust holes 24 is not symmetrical about the axis of the sealing cylinder 23. A drain plate 25 is provided on the inner wall of the sealing cylinder 23 on the side of each exhaust hole 24.

[0047] Specifically, the gas delivery method in the air inlet pipe 2 is divided into three release methods, namely: (1) When the temperature of the water body is low, the gas delivery volume of the air pump is relatively large. At this time, the positioning pipes 7 on both sides of the air inlet pipe 2 need to be ventilated at the same time, that is, the bubble pipes 5 on both sides of the air inlet pipe 2 need to generate microbubbles at the same time. At this time, the air outlets 18 on both sides of the air inlet pipe 2 need to be connected to the positioning pipes 7, and the driving component 22 (the driving component 22 is a device that can perform forward and reverse rotation at the output end, preferably an electric push rod) is started to drive the sealing cylinder 23 to rotate, so that the exhaust holes 24 on the sealing cylinder 23 that are symmetrical about the axis of the sealing cylinder 23 are connected to the positioning pipes 7, so that the gas in the driven pipe 3 can be discharged into each exhaust pipe 4 and the bubble pipe 5 at the same time, so that microbubbles can be released in each bubble pipe 5, so that the microbubbles released in each bubble pipe 5 can perform comprehensive anti-icing operation on the water body (such as Figure 12(as shown); (2) When the temperature in the water body is relatively high, the air pump's air delivery volume is relatively small. At this time, only the positioning pipe 7 on one side of the air inlet pipe 2 (e.g., the left side) needs to be ventilated to reduce the air pump's air delivery volume and to perform certain energy-saving treatment on the air pump. When microbubbles need to be generated in the bubble tube 5 on one side of the air inlet pipe 2 (e.g., the left side), the exhaust hole 24 on one side of the sealing cylinder 23 (e.g., the left side) needs to be connected to the positioning pipe 7 to seal the positioning pipe 7 on the other side of the air inlet pipe 2 (e.g., the right side). Start the drive component 22 to drive the sealing cylinder 23 to rotate. That is, at this time, the drive component 22 drives the exhaust hole 24 on the sealing cylinder 23 to be connected to the positioning pipe 7 on the same side (e.g., the left side), while the sealing cylinder 23 seals the positioning pipe 7 on different sides (e.g., the right side), so that gas is delivered in the positioning pipe 7 on one side (e.g., the left side) of the air inlet pipe 2, so that the positioning pipe 7 The gas inside is discharged from the driven pipe 3 into the exhaust pipe 4 and the bubble tube 5. The bubble tube 5 rotates in the water. Due to the rotation of the bubble tube 5 on one side of the air intake pipe 2 (e.g., the left side), the air intake pipe 2 will rotate around the positioning ring 6. This rotation of the bubble tube 5 drives the air intake pipe 2 to rotate simultaneously. The rotation of the bubble tube 5 in the water is equivalent to a "propeller". That is, the rotation of the bubble tube 5 in the water causes the side of the air intake pipe 2 (e.g., the left side) to be powered by the rotation of the bubble tube 5, causing the air intake pipe 2 to rotate. The rotation of the air intake pipe 2 drives the driven pipes 3, the exhaust pipe 4, and the bubble tube 5 to move synchronously. This increases the range of bubbles released in the exhaust pipe 4 and the bubble tube 5, allowing the bubbles released in the exhaust pipe 4 and the bubble tube 5 to provide anti-icing treatment for a larger water area. This not only saves energy but also increases the area of ​​water body that can be anti-iced (e.g., the area of ​​water body that can be anti-iced). Figure 13(as shown); (3) When the air intake pipe 2 rotates to a certain angle on one side of the first arc baffle 16, that is, when the air intake pipe 2 no longer rotates under the pulling action of the counterweight box 12 and the counterweight rope 11, only the positioning pipe 7 on the other side (e.g., the right side) of the air intake pipe 2 needs to be ventilated to reduce the air pump's output and to perform certain energy-saving treatment on the air pump. When microbubbles need to be generated in the bubble tube 5 on the other side (e.g., the right side) of the air intake pipe 2, the exhaust hole 24 on the other side (e.g., the right side) of the sealing cylinder 23 needs to be connected to the positioning pipe 7 to seal the positioning pipe 7 on one side (e.g., the left side) of the air intake pipe 2. Start the drive component 22 to drive the sealing cylinder 23 to rotate. That is, at this time, the drive component 22 drives the exhaust hole 24 on the sealing cylinder 23 to be connected to the positioning pipe 7 on the same side (e.g., the right side), while the sealing cylinder 23 seals the positioning pipe 7 on different sides (e.g., the left side), so that the positioning pipe 7 on the other side (e.g., the right side) of the air intake pipe 2 can be sealed. Gas is transported within the positioning tube 7, causing it to be discharged from the driven tube 3 into the exhaust pipe 4 and the bubble tube 5. The bubble tube 5 rotates within the water. Due to the rotation of the bubble tube 5 on the other side (e.g., the right side) of the air intake pipe 2, the air intake pipe 2 rotates around the positioning ring 6. This rotation of the bubble tube 5 simultaneously drives the air intake pipe 2 to rotate. The rotation of the bubble tube 5 within the water acts like a "propeller," meaning that the rotation of the bubble tube 5 causes the other side (e.g., the right side) of the air intake pipe 2 to rotate due to the force generated by its rotation. This rotation of the air intake pipe 2 drives the simultaneous movement of the driven tubes 3, exhaust pipe 4, and bubble tube 5, increasing the range of bubbles released from the exhaust pipe 4 and bubble tube 5. This allows the bubbles released from the exhaust pipe 4 and bubble tube 5 to provide anti-icing treatment over a larger water area, not only saving energy but also increasing the area of ​​water body protected from ice (e.g., ...). Figure 14As shown), the rotation of the bubble tube 5 in the water causes the other side (e.g., the right side) of the air inlet pipe 2 to be powered by the rotation of the bubble tube 5, causing the air inlet pipe 2 to rotate and return to its original position. This removes the tension between the counterweight box 12 and the counterweight rope 11, allowing the air inlet pipe 2 to float in the water. The rotation of the air inlet pipe 2 drives the synchronous movement of the driven pipes 3, the exhaust pipe 4, and the bubble tube 5, increasing the range of bubbles released from the exhaust pipe 4 and the bubble tube 5. This allows the bubbles released from the exhaust pipe 4 and the bubble tube 5 to provide anti-icing treatment to a larger water area, which not only saves energy but also increases the anti-icing area of ​​the water body. While the sealing cylinder 23 rotates, the sealing cylinder... 23 drives the drain plate 25 to rotate, and the drain plate 25 can guide the gas in the sealing cylinder 23 to a certain extent, so that the gas can be smoothly discharged from the exhaust pipe 4. Even if the bellows 1, the inlet pipe 2, the driven pipe 3 and the exhaust pipe 4 leak, and there is liquid residue in the inlet pipe 2 and the sealing cylinder 23, the drive component 22 is activated to drive the sealing cylinder 23 to rotate. The sealing cylinder 23 drives the drain plate 25 to rotate, so that the drain plate 25 can discharge the liquid in the sealing cylinder 23 from the positioning pipe 7 along with the gas. Even if there is liquid in the sealing cylinder 23, the gas is discharged from the positioning pipe 7 at the same time as the sealing cylinder 23 drives the drain plate 25 to rotate, so that even if there is liquid residue in the sealing cylinder 23, it will not affect the bubble anti-icing.

[0048] In another embodiment of the present invention, each of the exhaust pipes 4 is connected to a horizontal pipe 19 at both ends. The same exhaust pipe 4 and the horizontal pipes 19 at both ends are connected to form an "I" shaped pipe fitting. A circular baffle 20 is rotatably arranged on the pipe wall of each of the horizontal pipes 19. The side wall of each circular baffle 20 is connected to the pipe wall of the horizontal pipe 19 by an elastic member 21. Each circular baffle 20 is sealed to its corresponding horizontal pipe 19. The circular baffles 20 in the horizontal pipes 19 at both ends of the same exhaust pipe 4 are staggered.

[0049] Specifically, when anti-icing treatment is required on the water surface, there are two ways to transport gas through the exhaust pipe 4 and the horizontal pipe 19: (1) When the temperature of the water body is low, the gas pump has a relatively large gas delivery volume. At this time, the positioning pipes 7 on both sides of the air inlet pipe 2 need to be ventilated at the same time. That is, the exhaust pipes 4 and the horizontal pipe 19 on both sides of the air inlet pipe 2 need to transport gas at the same time. When the ends of each horizontal pipe 19 need to generate microbubbles at the same time, the gas inlet pipe 2 and the horizontal pipe 19 have a large gas intake volume. The gas pushes the circular baffle. The circular baffle 20 rotates within the horizontal tube 19, stretching the elastic element 21 (which is a retractable and restorative element, preferably a spring) so that the elastic element 21 is in a stretched state. This prevents the circular baffle 20 from blocking the horizontal tube 19, allowing the gas in the exhaust pipe 4 to be simultaneously discharged from both ends of the two horizontal tubes 19 into the water. This releases microbubbles from both ends of the horizontal tubes 19, increasing the number of microbubbles released into the water and enabling stable anti-icing operation of the water (e.g., ...). Figure 9 (as shown); (2) When the temperature in the water body is relatively high, the air pump output is relatively small. At this time, only one end of the horizontal pipe 19 needs to release microbubbles. At this time, due to the small air intake of the air in the air inlet pipe 2 and the horizontal pipe 19, the circular baffle 20, under the rebound action of the elastic element 21, makes the circular baffle 20 block one end of the horizontal pipe 19, while the other end of the horizontal pipe 19 is open. The open ends of the two horizontal pipes 19 on the same exhaust pipe 4 are corresponding ends (that is, the open ends of the two horizontal pipes 19 on the same exhaust pipe 4 and the exhaust pipe 4 are combined to form a Z-shaped pipe). The bellows 1 and the horizontal pipe 19 rotate when microbubbles are released from the exhaust pipe 4 and the horizontal pipe 19. Because the bellows 1 has a certain degree of elasticity, the horizontal pipe 19 rotates while simultaneously causing the intake pipe 2 to move axially, keeping the bellows 1 in a stretched state. When the intake pipe 2 moves axially, it simultaneously drives each horizontal pipe 19 to move synchronously, increasing the range of microbubbles released from the intake pipe 2 and the horizontal pipe 19. This allows the bubbles released from the horizontal pipe 19 to provide anti-icing treatment for a larger water area, not only saving energy but also increasing the anti-icing area of ​​the water body (e.g., ...). Figure 8 (As shown).
