[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.14 The present invention is further described in detail.

[0036] An embodiment provided by the present invention relates to an anti-icing and anti-freezing device for a dam body, comprising an air pump, wherein the output end of the air pump is connected to an air intake pipe 2, wherein the air intake pipe 2 is suspended in a water body, and further comprising a bubble unit, wherein the bubble unit comprises a driven pipe 3, wherein a plurality of driven pipes 3 are evenly arranged on the air intake pipe 2 along its axial direction in a rotationally matched manner, wherein a plurality of exhaust pipes 4 are evenly arranged on each of the driven pipes 3 along its axial direction, wherein a bubble tube 5 is respectively arranged at both ends of each of the exhaust pipes 4, and the same exhaust pipe 4 and the bubble tubes 5 at both ends thereof are connected to form a Z-shaped pipe fitting.

[0037] Specifically, the air pump is used to force gas into the air intake pipe 2. The output end of the air pump is connected to a movable pipe (such as a bellows 1) so that the air intake pipe 2 suspended in the water body can move within a certain range. The bellows 1 is a flexible pipe body that can be extended and retracted and slightly rotated. A positioning ring 6 is connected to the bellows 1. The positioning ring 6 is rotatably connected to the air intake pipe 2 so that the air intake pipe 2 can rotate on the positioning ring 6. The air intake pipe 2 is preferably an "L"-shaped pipe fitting. The vertical section of the air intake pipe 2 is rotatably connected to the positioning ring 6. The horizontal section of the air intake pipe 2 is evenly provided with a plurality of driven pipes 3 in a rotatable manner along its axial direction. Each driven pipe 3 is vertically connected to the horizontal section of the air intake pipe 2. The driven pipe 3 is vertically arranged, each driven pipe 3 is perpendicular to the vertical section of the intake pipe 2, a plurality of exhaust pipes 4 are evenly arranged on the driven pipe 3 along its axial direction, each exhaust pipe 4 is perpendicular to the corresponding driven pipe 3, the middle of each exhaust pipe 4 is connected to the driven pipe 3, a bubble tube 5 is arranged at each end of each exhaust pipe 4, the same exhaust pipe 4 is connected to the bubble tubes 5 at both ends to form a Z-shaped pipe fitting, and an exhaust hole is arranged at the end of the bubble tube 5. When the water surface needs to be anti-iced, the staff places the intake pipe 2 in the water body and arranges it to be suspended. Through the expansion and contraction of the bellows 1, the vertical section of the intake pipe 2 is perpendicular to the water surface, and the air pump is started to pass the bellows 1 and the intake pipe 2 is transported to the driven tube 3, and the gas in the driven tube 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, micro bubbles are generated when the gas is discharged from the exhaust hole of the bubble tube 5, so that the micro bubbles discharged from the exhaust hole of the bubble tube 5 can prevent the water surface from freezing (the energy of the micro bubble rupture can prevent the aggregation of ice crystals in the water and effectively prevent the formation of ice layer), and 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 fitting, 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 tube 5. The gas in the bubble tube 5 is discharged into the water body, and the bubble tube 5 and the exhaust pipe 4 are connected to form a Z-shaped pipe fitting. Under the driving force of the gas in the water body, the bubble tube 5 and the exhaust pipe 4 can rotate, so that the exhaust pipe 4 and the bubble tube 5 drive the driven pipe 3 to rotate on the intake pipe 2, so that the microbubbles discharged from the bubble tube 5 can move in multiple directions, making the movement range of the microbubbles wider, increasing the anti-icing water surface range of the bubbles, and the exhaust pipe 4 and the bubble tube 5 do not fit on the bottom wall of the dam at the bottom of the water when rotating, which can greatly reduce the risk of clogging of the bubble tube 5. Even if a small amount of foreign matter blocks the bubble tube 5 when it rotates, the bubble tube 5 can throw the blockage out of the bubble tube 5 when it rotates, so that the bubble tube 5 will not be blocked, thereby improving the stability of the bubble tube 5 in generating microbubbles.

[0038] The disadvantage of the prior art is that most of the existing anti-icing devices are fixedly installed on the dam body, and the nozzle of the bubble generator is fixedly connected to the outlet pipe. There are certain foreign matter in the water body, and the pollutants in the water body often clog the bubble generator, which needs to be taken out for cleaning, which is more troublesome.

[0039] The beneficial effect of this embodiment is that when it is necessary to perform anti-icing treatment on the water surface, the air intake pipe 2 is placed in the water body, and the air pump is started to transport the air to the driven pipe 3 through the bellows 1 and the air intake pipe 2, and 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, so that the microbubbles discharged from the exhaust hole of the bubble tube 5 can prevent the water surface from freezing, and 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, so that the exhaust pipe 4 and the bubble tube 5 drive the driven pipe 3 to rotate on the air intake pipe 2, and when the exhaust pipe 4 and the bubble tube 5 rotate, the risk of blockage of the bubble tube 5 can be greatly reduced. Even if a small amount of foreign matter blocks the bubble tube 5 when it rotates, the bubble tube 5 can throw the blockage out of the bubble tube 5 when it rotates, so that the bubble tube 5 will not be blocked, thereby improving the stability of the bubble tube 5 in generating microbubbles.

[0040] Preferably, the bubble unit also includes a positioning tube 7, and a plurality of positioning tubes 7 are evenly arranged on both sides of the outer wall of the intake pipe 2 along its axial direction. The positioning tubes 7 evenly arranged on both sides of the intake pipe 2 are staggered with each other, and a spherical groove is provided at the end of the positioning tube 7. A spherical part 8 is movably installed in each of the spherical grooves, and each of the spherical parts 8 is connected to a driven tube 3 to transport the gas in the intake pipe 2 to the driven tube 3.

[0041] Specifically, since the positioning tube 7 and the driven tube 3 are movably connected through the spherical member 8 and the spherical groove on the positioning tube 7, microbubbles are generated when the gas is discharged from the exhaust hole of the bubble tube 5. Since the same exhaust tube 4 and the bubble tubes 5 at both ends are connected to form a Z-shaped tube, the gas flows from the middle of the exhaust tube 4 to the bubble tubes 5 at both ends, and 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 tube 4 can rotate, so that the exhaust tube 4 and the bubble tube 5 drive the driven tube 3 to rotate on the intake pipe 2. The driven pipe 3 is dynamically connected so that the driven pipe 3 swings on the intake pipe 2, so that the driven pipe 3 can drive the exhaust pipe 4 and the bubble tube 5 to swing, so that the microbubbles discharged from the bubble tube 5 can move in multiple directions, making the movement range of the microbubbles wider, increasing the anti-icing water surface range of the bubbles, and when the exhaust pipe 4 and the bubble tube 5 swing, the risk of blockage of the bubble tube 5 can be greatly reduced. Even if a small amount of foreign matter blocks the bubble tube 5 when it swings, the bubble tube 5 can throw the blockage out of the bubble tube 5 when it swings, so that the bubble tube 5 will not be blocked, thereby improving the stability of the bubble tube 5 in generating microbubbles.

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

[0043] Specifically, before the staff places the air intake pipe 2 into the water body, they first place a ballast block 13 of appropriate weight in the ballast box 12, and place the ballast box 12 into the water body. The ballast box 12 and the ballast block 13 drive the air intake pipe 2 to move toward the bottom of the water through the ballast rope 11. At the same time, the floating member 10 (the floating member 10 can float on the water surface, so that the floating member 10 can provide buoyancy for the floating rope 9) floats on the water surface, so that the floating member 10 provides a floating tension to the air intake pipe 2 through the floating rope 9, so that the air intake pipe 2 can be suspended in the water body, and the exhaust pipe 4 and the bubble tube 5 can drive the air intake pipe 2 to move in the water body when swinging. The floating movement is performed so that the air intake pipe 2 can move to a suitable anti-icing position, and 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 body 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 body can be adjusted accordingly. The depth of the air intake pipe 2 in the water body is adjusted, and the water depth of the microbubbles generated by the exhaust pipe 4 and the bubble tube 5 in the water body changes, so that the microbubbles generated in the exhaust pipe 4 and the bubble tube 5 can perform stable anti-icing treatment on the water body.

[0044] In another embodiment provided by the present invention, an active component 14 is provided at the end of the air inlet pipe 2; a connecting rod 15 is connected to the output end of the active component 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, and the first arc-shaped baffle 16 and the second arc-shaped baffle 17 are provided with a sliding seal for the positioning tube 7; a plurality of air outlet holes 18 are evenly arranged on the first arc-shaped baffle 16 and the second arc-shaped baffle 17, and two adjacent air outlet holes 18 opened from the ends of the first arc-shaped baffle 16 and the second arc-shaped baffle 17 are grouped, and each group of air outlet holes 18 and its corresponding positioning tube 7 are interconnected and coordinated; the spacing between a group of air outlet holes 18 on the first arc-shaped baffle 16 is greater than the spacing between a group of air outlet holes 18 on the second arc-shaped baffle 17.

[0045] Specifically, the spacing between a group of air outlet holes 18 on the first arc-shaped baffle plate 16 is greater than the spacing between a group of air outlet holes 18 on the second arc-shaped baffle plate 17, that is, the spacing between a group of air outlet holes 18 on the first arc-shaped baffle plate 16 (that is, two adjacent air outlet holes 18 interconnected with the same positioning tube 7) is greater than the spacing between a group of air outlet holes 18 on the second arc-shaped baffle plate 17 (that is, two adjacent air outlet holes 18 interconnected with the same positioning tube 7). When one air outlet hole 18 at one end of each group of air outlet holes 18 on the first arc-shaped baffle plate 16 close to the active member 14 is butted against the positioning tube 7, When connected, one air outlet hole 18 of each group of air outlet holes 18 on the second arc baffle 17 close to one end of the active member 14 is not connected to the positioning tube 7 (that is, the second arc baffle 17 blocks the positioning tube 7); when one air outlet hole 18 of each group of air outlet holes 18 on the second arc baffle 17 close to one end of the active member 14 is connected to the positioning tube 7, one air outlet hole 18 of each group of air outlet holes 18 on the first arc baffle 16 close to one end of the active member 14 is not connected to the positioning tube 7 (that is, the first arc baffle 16 blocks the positioning tube 7); when the first arc baffle 16 and the second arc baffle 16 are connected, one air outlet hole 18 of each group of air outlet holes 18 on the second arc baffle 17 close to one end of the active member 14 is not connected to the positioning tube 7 (that is, the first arc baffle 16 blocks the positioning tube 7); When one of the air outlet holes 18 at one end of each group of air outlet holes 18 on the baffle plate 17 away from the active member 14 is connected to the positioning tube 7; the corresponding gas delivery mode in the air inlet pipe 2 is divided into three release modes, namely: (1) When the temperature in the water body is low, the air delivery volume of the air pump is relatively large. 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, micro bubbles need to be generated in the bubble tubes 5 on both sides of the air inlet pipe 2 at the same time. At this time, the air outlet holes 18 on both sides of the air inlet pipe 2 need to be connected to the positioning tube 7, and the active member 14 (the active member 14 is an output end that can perform linear reciprocating motion) is started. The device, preferably an electric push rod, drives the connecting rod 15 to move toward one end of the end close to the air inlet pipe 2. That is, at this time, the active member 14 contracts and synchronously drives the first arc baffle 16 and the second arc baffle 17 to move through the connecting rod 15, so that the air outlet holes 18 on the first arc baffle 16 and the second arc baffle 17 are simultaneously connected to the positioning tube 7, so that the gas in the driven pipe 3 can be discharged into each exhaust pipe 4 and the bubble tube 5 at the same time, so that microbubbles can be released in each bubble tube 5, so that the microbubbles released in each bubble tube 5 can perform comprehensive anti-icing operations on the water body (such as Figure 5(2) When the temperature in the water body is relatively high, the gas delivery of the air pump is relatively small. At this time, only the positioning tube 7 on one side of the air inlet pipe 2 needs to be ventilated to reduce the gas delivery of the air pump 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 to the positioning tube 7, and the positioning tube 7 on the other side of the air inlet pipe 2 needs to be closed. The active member 14 is started to drive the connecting rod 15 to move, that is, at this time, the active member 14 drives the first arc baffle 16 and the second arc baffle 17 to move synchronously through the connecting rod 15, so that the air outlet 18 on the first arc baffle 16 is connected to the positioning tube 7 on the same side, and the second arc baffle 17 blocks the positioning tube 7 on the same side, so that gas is delivered to the positioning tube 7 on the side of the first arc baffle 16 in the air inlet pipe 2. The air in the positioning tube 7 is discharged from the driven tube 3 into the exhaust pipe 4 and the bubble tube 5. The bubble tube 5 rotates in the water body. As the bubble tube 5 on one side of the air inlet pipe 2 rotates, the air inlet pipe 2 rotates around the positioning ring 6 as the center under the rotation of the bubble tube 5, so that the bubble tube 5 drives the air inlet pipe 2 to rotate while rotating. The rotation of the bubble tube 5 in the water body is equivalent to a "propeller", that is, the rotation of the bubble tube 5 in the water body causes one side of the air inlet pipe 2 to be affected by the power generated by the rotation of the bubble tube 5, so that the air inlet pipe 2 rotates, and the rotation of the air inlet pipe 2 drives each driven tube 3, the exhaust pipe 4 and the bubble tube 5 to move synchronously, so that the range of the bubbles released in the exhaust pipe 4 and the bubble tube 5 is increased, so that the bubbles released in the exhaust pipe 4 and the bubble tube 5 can perform anti-icing treatment on a larger water area, which can not only save energy but also increase the anti-icing area of ​​the water body (such as Figure 4(3) when the air intake pipe 2 is located on the side of the first arc-shaped baffle plate 16 and rotates to a certain angle, that is, under the pulling action of the counterweight box 12 and the counterweight rope 11, the air intake pipe 2 no longer rotates, the active member 14 is started to drive the connecting rod 15 to move, that is, at this time, the active member 14 synchronously drives the first arc-shaped baffle plate 16 and the second arc-shaped baffle plate 17 to move through the connecting rod 15, so that the air outlet hole 18 on the second arc-shaped baffle plate 17 is connected with the positioning tube 7 on the same side thereof, and the first arc-shaped baffle plate 16 blocks the positioning tube 7 on the same side thereof, so that gas is transported in the positioning tube 7 on the side of the second arc-shaped baffle plate 17 in the air intake pipe 2, so that the gas in the positioning tube 7 is discharged from the driven tube 3 into the exhaust pipe 4 and the bubble tube 5, and the bubble tube 5 rotates in the water body. Due to the rotation of the bubble tube 5 on one side of the air intake pipe 2, the air intake pipe 2 will rotate in a positioning ring under the rotation of the bubble tube 5. 6 is the center of rotation, so that the bubble tube 5 drives the air intake pipe 2 to rotate while rotating. The rotation of the bubble tube 5 in the water body is equivalent to a "propeller", that is, the rotation of the bubble tube 5 in the water body causes one side of the air intake pipe 2 to be subjected to the power generated by the rotation of the bubble tube 5, so that the air intake pipe 2 will rotate, so that the air intake pipe 2 can rotate back to its original position, so that the counterweight box 12 and the counterweight rope 11 no longer tighten the air intake pipe 2, so that the air intake pipe 2 can perform a certain floating movement in the water body, and the rotation of the air intake pipe 2 drives each driven pipe 3, the exhaust pipe 4 and the bubble tube 5 to move synchronously, so that the range of bubbles released in the exhaust pipe 4 and the bubble tube 5 is increased, so that the bubbles released in the exhaust pipe 4 and the bubble tube 5 can perform anti-icing treatment on a larger water area, which can not only save energy but also increase the anti-icing area of ​​the water body, and the air intake pipe 2 can rotate back to the position before the first arc-shaped baffle 16 is ventilated (such as Figure 3 As shown); both the above states (2) and (3) can save energy and can be rotated to a certain angle and returned to its original position, thereby increasing the anti-icing area of ​​the water body.

[0046] In another embodiment provided by the present invention, a driving member 22 is provided at the end of the intake pipe 2, and the output end of the driving member 22 is connected to a sealing cylinder 23, and the sealing cylinder 23 is rotatably sealed and arranged on the inner wall of the intake pipe 2, and a plurality of groups of exhaust holes 24 are evenly arranged in the axial direction of the sealing cylinder 23, each group of exhaust holes 24 is composed of two exhaust holes 24, and each of the exhaust holes 24 is connected to the corresponding positioning tube 7, and the spacing between each group of exhaust holes 24 on two adjacent positioning tubes 7 is different, and in the circumferential direction of the sealing cylinder 23: the spacing between the two exhaust holes 24 corresponding to one positioning tube 7 is different from the spacing between the two exhaust holes 24 corresponding to another adjacent positioning tube 7, and one exhaust hole 24 of each group of exhaust holes 24 is symmetrical with respect to the axis of the sealing cylinder 23, while another exhaust hole 24 of each group of exhaust holes 24 is not symmetrical with respect to the axis of the sealing cylinder 23, and a drainage plate 25 is provided on the inner wall of the sealing cylinder 23 at the side of each exhaust hole 24.

[0047] Specifically, the gas delivery mode in the air intake pipe 2 is divided into three release modes, which are: (1) when the temperature in the water body is low, the gas delivery volume of the air pump is relatively large. At this time, the positioning tubes 7 on both sides of the air intake pipe 2 need to be ventilated at the same time, that is, microbubbles need to be generated in the bubble tubes 5 on both sides of the air intake pipe 2 at the same time. At this time, the air outlet holes 18 on both sides of the air intake pipe 2 need to be connected with the positioning tubes 7, and the driving member 21 is started (the driving member 21 is a device with forward and reverse motion at the output end, preferably an electric push rod) 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 with the positioning tube 7, so that the gas in the driven tube 3 can be discharged into each exhaust pipe 4 and the bubble tube 5 at the same time, so that microbubbles can be released in each bubble tube 5, so that the microbubbles released in each bubble tube 5 can perform comprehensive anti-icing operations on the water body (such as Fig.12As shown); (2) when the temperature in the water body is relatively high, the air delivery of the air pump is relatively small. At this time, only the positioning tube 7 on one side (such as the left side) of the air inlet pipe 2 needs to be ventilated to reduce the air delivery of the air pump and perform certain energy-saving treatment on the air pump. When microbubbles need to be generated in the bubble tube 5 on one side (such as the left side) of the air inlet pipe 2, the exhaust hole 24 on one side (such as the left side) of the sealing tube 23 needs to be connected to the positioning tube 7, and the positioning tube 7 on the other side (such as the right side) of the air inlet pipe 2 is closed, and the driving member 21 is started to drive the sealing tube 23 to rotate, that is, at this time, the driving member 21 drives the exhaust hole 24 on the sealing tube 23 to be connected to the positioning tube 7 on the same side (such as the left side), and the sealing tube 23 performs a blocking operation on the positioning tube 7 on the different side (such as the right side), so that gas is transported in the positioning tube 7 on one side (such as the left side) of the air inlet pipe 2, so that the positioning tube 7 The gas in the water 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 body. Since the bubble tube 5 on one side (such as the left side) of the intake pipe 2 rotates, the intake pipe 2 will rotate around the positioning ring 6 under the rotation of the bubble tube 5, so that the bubble tube 5 drives the intake pipe 2 to rotate while rotating. The rotation of the bubble tube 5 in the water body is equivalent to a "propeller", that is, the rotation of the bubble tube 5 in the water body causes one side (such as the left side) of the intake pipe 2 to be affected by the power generated by the rotation of the bubble tube 5, so that the intake pipe 2 will rotate, and the rotation of the intake pipe 2 drives each driven pipe 3, the exhaust pipe 4 and the bubble tube 5 to move synchronously, so that the range of the bubbles released in the exhaust pipe 4 and the bubble tube 5 is increased, so that the bubbles released in the exhaust pipe 4 and the bubble tube 5 can perform anti-icing treatment on a larger water area, which can not only save energy but also increase the anti-icing area of ​​the water body (such as Fig.13(3) when the air inlet pipe 2 is located on one side of the first arc-shaped baffle 16 and rotates to a certain angle, that is, under the pulling action of the counterweight box 12 and the counterweight rope 11, the air inlet pipe 2 no longer rotates, at this time, only the positioning tube 7 on the other side (such as the right side) of the air inlet pipe 2 needs to be ventilated to reduce the air delivery of the air pump and perform certain energy-saving treatment on the air pump. When microbubbles need to be generated in the bubble tube 5 on the other side (such as the right side) of the air inlet pipe 2, the exhaust hole 24 on the other side (such as the right side) of the sealing cylinder 23 needs to be connected with the positioning tube 7, and the positioning tube 7 on one side (such as the left side) of the air inlet pipe 2 is closed, and the driving member 21 is started to drive the sealing cylinder 23 to rotate, that is, at this time, the driving member 21 drives the exhaust hole 24 on the sealing cylinder 23 to be connected with the positioning tube 7 on the same side (such as the right side), and the sealing cylinder 23 performs a blocking operation on the positioning tube 7 on the different side (such as the left side), so that the positioning tube 7 on the other side (such as the right side) of the air inlet pipe 2 The positioning tube 7 has gas for transport, so that the gas in the positioning tube 7 is discharged from the driven tube 3 into the exhaust pipe 4 and the bubble tube 5. The bubble tube 5 rotates in the water body. Since the bubble tube 5 on the other side (such as the right side) of the intake pipe 2 rotates, the intake pipe 2 will rotate around the positioning ring 6 under the rotation of the bubble tube 5, so that the bubble tube 5 drives the intake pipe 2 to rotate while rotating. The rotation of the bubble tube 5 in the water body is equivalent to a "propeller", that is, the rotation of the bubble tube 5 in the water body causes the other side (such as the right side) of the intake pipe 2 to be affected by the power generated by the rotation of the bubble tube 5, so that the intake pipe 2 will rotate, and the rotation of the intake pipe 2 drives the driven tubes 3, the exhaust pipe 4 and the bubble tube 5 to move synchronously, so that the range of the bubbles released in the exhaust pipe 4 and the bubble tube 5 is increased, so that the bubbles released in the exhaust pipe 4 and the bubble tube 5 can perform anti-icing treatment on a larger water area, which can not only save energy but also increase the anti-icing area of ​​the water body (such as Fig.14As shown), that is, the bubble tube 5 rotates in the water body so that the other side of the air intake pipe 2 (such as the right side) is affected by the power generated by the rotation of the bubble tube 5, so that the air intake pipe 2 rotates, so that the air intake pipe 2 can rotate back to its original position, so that the counterweight box 12 and the counterweight rope 11 no longer tighten the air intake pipe 2, so that the air intake pipe 2 can perform a certain floating movement in the water body, and the rotation of the air intake pipe 2 drives each driven pipe 3, the exhaust pipe 4 and the bubble tube 5 to move synchronously, so that the range of the bubbles released in the exhaust pipe 4 and the bubble tube 5 is increased, so that the bubbles released in the exhaust pipe 4 and the bubble tube 5 can perform anti-icing treatment on a larger water area, which can not only save energy but also increase the anti-icing area of ​​the water body; while the sealing cylinder 23 rotates, the sealing cylinder 23 23 drives the drain plate 25 to rotate, and the drain pipe 25 can guide the gas in the sealing tube 23 to a certain extent, so that the gas can be discharged from the exhaust pipe 4 smoothly; even if the bellows 1, the intake pipe 2, the driven pipe 3 and the exhaust pipe 4 leak, when there is liquid residue in the intake pipe 2 and the sealing tube 23, the driving member 21 is started to drive the sealing tube 23 to rotate, and the sealing tube 23 drives the drain plate 25 to rotate, so that the drain plate 25 can discharge the liquid in the sealing tube 23 from the positioning tube 7 together with the gas, even if there is liquid in the sealing tube 23, the sealing tube 23 drives the drain plate 25 to rotate, and the gas is discharged from the positioning tube 7, so that even if there is liquid residue in the sealing tube 23, it will not affect the bubble anti-icing.

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

[0049] Specifically, when the water surface needs to be anti-iced, there are two ways of delivering gas through the exhaust pipe 4 and the cross pipe 19, namely: (1) when the temperature in the water body is low, the gas delivery of the air pump is relatively large. At this time, the positioning pipes 7 on both sides of the intake pipe 2 need to be ventilated at the same time, that is, the exhaust pipes 4 and the cross pipe 19 on both sides of the intake pipe 2 need to deliver gas at the same time, and the ends of each cross pipe 19 need to generate microbubbles at the same time. At this time, due to the large intake volume of gas in the intake pipe 2 and the cross pipe 19, the gas pushes the circular baffle The circular baffle 20 rotates in the transverse pipe 19, and the circular baffle 20 stretches the elastic member 21 (the elastic member 21 is a component that can be retracted and reset, preferably a spring), so that the elastic member 21 is in a stretched state, so that the circular baffle 20 no longer blocks the transverse pipe 19, so that the gas in the exhaust pipe 4 is discharged into the water body from both ends of the two transverse pipes 19 synchronously, so that both ends of the transverse pipe 19 can release microbubbles, so that the number of microbubbles released by the transverse pipe 19 in the water body increases, and stable anti-icing operations can be performed on the water body (such as Fig. 9 (2) When the temperature in the water body is relatively high, the air delivery of the air pump is relatively small. At this time, only one end of the transverse pipe 19 is needed to release microbubbles. At this time, due to the small air intake volume of the gas in the air intake pipe 2 and the transverse pipe 19, the circular baffle 20 is caused to block one end of the transverse pipe 19 under the rebound effect of the elastic member 21, while the other end of the transverse pipe 19 is in an open state. The open ends of the two transverse pipes 19 on the same exhaust pipe 4 are corresponding to each other (that is, the open ends of the two transverse pipes 19 on the same exhaust pipe 4 and the exhaust pipe 4 are combined into a Z-shaped pipe). The bellows 1 has a certain elasticity, so that the transverse tube 19 can drive the intake pipe 2 to perform a certain axial stretching movement while rotating, so that the bellows 1 is in a stretched state. When the intake pipe 2 moves axially, the intake pipe 2 drives each transverse tube 19 to move synchronously, so that the range of microbubbles released from the intake pipe 2 and the transverse tube 19 is increased, so that the bubbles released from the transverse tube 19 can perform anti-icing treatment on a larger water area, which can not only save energy but also increase the anti-icing area of ​​the water body (such as Figure 8 shown).
