[0033] The disadvantages of the prior art are that the bubble anti-icing device is mostly fixedly arranged on the side wall of the dam body 8, the air outlet pipe 2 of the bubble anti-icing device is also fixedly installed, the bubble anti-icing device is easily affected by the dirty environment under the water, the probability of blockage is increased, the anti-icing range of the bubble anti-icing device is small, and the anti-icing range of the bubble anti-icing device is fixed.

[0034] The beneficial effects of the present application are that the gas pump is used to convey gas into the air inlet pipe body 1 and the air outlet pipe 2, the air outlet pipe 2 generates bubbles in the water body, the floating body 4 moves on the water surface, the floating body 4 drives the air inlet pipe body 1 and the air outlet pipe 2 to move through the connecting rope 5, the air outlet pipe 2 has a certain moving range, the range of the micro-bubbles released in the air outlet pipe 2 is increased, the area of the water surface anti-icing is increased, the situation that the water surface of the dam body 8 is partially iced is prevented, the water surface anti-icing effect of the dam body 8 is improved, and the blockage probability of the air outlet pipe 2 is greatly reduced through the shaking of the air outlet pipe 2 in the water body.

[0035] Further, a plurality of counterweight ropes 9 are uniformly connected to the outer wall of the air inlet pipe body 1 along the axial direction thereof, each of the counterweight ropes 9 is located between two adjacent air outlet pipes 2 on the air inlet pipe body 1, each of the counterweight ropes 9 is connected with a counterweight box 10, each of the counterweight boxes 10 is threadedly connected with a box cover 11 at the bottom end thereof, a plurality of counterweight blocks 12 are arranged in each of the counterweight boxes 10, the number of the counterweight blocks 12 in each of the counterweight boxes 10 is optional, specifically, before the air inlet pipe body 1 is placed into the water body by the staff, the staff uses a tool to open the box cover 11 at the bottom end of the counterweight box 10, then adjusts the number of the counterweight blocks 12 in the counterweight box 10 according to the buoyancy generated by the floating body 4 on the water surface, and adjusts the length of the counterweight rope 9 according to the depth of the water body, when the air inlet pipe body 1 is placed into the water body, the counterweight box 10 and the counterweight block 12 sink into the water bottom, the counterweight box 10 and the counterweight block 12 exert a certain counterweight pulling force on the air inlet pipe body 1 through the counterweight rope 9, the movement range of the air inlet pipe body 1 is controlled, the movement range of the air inlet pipe body 1 and the air outlet pipe 2 is within the range close to the side wall of the dam body 8, the range of the micro-bubbles released in the air outlet pipe 2 is on the side close to the side wall of the dam body 8, the micro-bubbles released in the air outlet pipe 2 can be released at the position of the dam body 8, the situation that the water surface of the dam body 8 is partially iced is prevented, and the water surface anti-icing effect of the dam body 8 is improved.

[0036] In another embodiment, the outer wall of the air inlet pipe body 1 is uniformly provided with a plurality of arc-shaped through holes 13 along the axial direction, each of the arc-shaped through holes 13 is slidably and sealingly provided with an arc-shaped plate 14, each of the arc-shaped plates 14 is provided with a connecting pipe 15, and each of the connecting pipes 15 is in communication with the air inlet pipe body 1; the two end side walls of each of the arc-shaped through holes 13 in the axial direction of the air inlet pipe body 1 are provided with a groove 16, that is, one groove 16 is provided on one side wall of the same arc-shaped through hole 13, two grooves 16 are provided on the two side walls of the same through groove in correspondence, each of the grooves 16 is slidably and sealingly provided with an arc-shaped plate 17 (the arc-shaped plate 17 is used to realize the dynamic sealing between the arc-shaped plate 14 and the air inlet pipe body 1), and each of the arc-shaped plates 14 in each of the arc-shaped through holes 13 is connected with an arc-shaped plate 17 on both sides, that is, two arc-shaped plates 17 are connected through an arc-shaped plate 14; each of the arc-shaped plates 17 in each of the arc-shaped through holes 13 and the inner wall of the corresponding groove 16 are connected through a first elastic member 18, that is, one arc-shaped plate 17 in one arc-shaped through hole 13 and the inner wall of the corresponding groove 16 are connected through a first elastic member 18.

[0037] Specifically, the connecting pipe 15 and the arc panel 14 are arranged perpendicularly to each other. Since the air outlet pipe 2 is arranged vertically and the sliding seal is arranged in the connecting pipe 15, when the air inlet pipe body 1 is placed in the water body, the air outlet pipe 2 slides to the end of the connecting pipe 15 under the action of gravity. That is, the air outlet pipe 2 slides to the position where the end of the connecting pipe 15 is limited. When the gas is transported in the air inlet pipe body 1, the air inlet pipe body 1 transports the gas into the connecting pipe 15 and the air outlet pipe 2. Since the air inlet pipe body 1 is connected vertically to the connecting pipe 15, when the gas in the air inlet pipe body 1 enters the connecting pipe 15, the gas needs to be bent at a certain angle, so that part of the gas acts on the side wall of the connecting pipe 15 away from the flexible hose 6. Preferably, the top end of the connecting pipe 15 is provided with a passive plate 38. When the gas enters the connecting pipe 15 from the air inlet pipe body 1, the gas blows the passive plate 38 to move away from the flexible hose 6, so that the passive plate 38 drives the connecting pipe 15 to move away from the flexible hose 6. The passive plate realizes the functions of guiding and force driving, so that the connecting pipe 15 drives the arc panel 14 to slide in the arc through hole 13. When the arc panel 14 slides in the arc through hole 13, the arc panel 14 drives the arc plate 17 to slide in the arc through hole 13. The arc plate 17 stretches the first elastic member 18 (the first elastic member 18 is an element capable of stretching and resetting, preferably a spring). When the force of the gas on the connecting pipe 15 is offset by the elastic force of the first elastic member 18, the first elastic member 18 pulls back the arc plate 17 and the arc plate 17. When the gas is transported in the connecting pipe 15 and the air inlet pipe body 1, the arc panel 14 can slide linearly in the arc through hole 13. The arc panel 14 can drive the connecting pipe 15 and the air outlet pipe 2 to move linearly, so that the air outlet pipe 2 can increase the release range of the micro-bubbles when moving linearly, increase the ice prevention range of the water surface, effectively prevent the dam body 8 from icing, and greatly reduce the probability of blockage of the air outlet pipe 2 through the shaking of the air outlet pipe 2 in the water body.

[0038] Preferably, each sliding seal in each connecting pipe 15 is provided with an air outlet pipe 2. The top end of each connecting pipe 15 is rotatably provided with a reset ring 19. The top end of each reset ring 19 and the corresponding air outlet pipe 2 are connected by a second elastic member 20.

[0039] Specifically, when the gas is transported in the connecting pipe 15 to the outlet pipe 2, the outlet pipe 2 is subjected to the blowing force of the gas and its own gravity, so that the outlet pipe 2 slides in the connecting pipe 15 to the end formed thereby. During the sliding of the outlet pipe 2 in the connecting pipe 15, the outlet pipe 2 performs a certain stretching operation on the second elastic member 20 (the second elastic member 20 is an element capable of elastic recovery, and is preferably a plurality of rubber ropes or rubber cylinders), so that the second elastic member 20 is in a stretched state. When the gas transportation amount is small, the force of the gas acting on the outlet pipe 2 decreases, and under the elastic recovery of the second elastic member 20, the second elastic member 20 drives the outlet pipe 2 to slide towards the water surface end, so that the micro-bubbles released in the outlet pipe 2 are closer to the water surface end. When the gas transportation amount changes, the second elastic member 20 can drive the outlet pipe 2 to perform linear reciprocating motion, so that the movement range of the micro-bubbles released in the outlet pipe 2 in the water body is increased, the ice-prevention effect of the bubbles is improved, and through the shaking of the outlet pipe 2 in the water body, the probability of clogging of the outlet pipe 2 can be greatly reduced.

[0040] In still another embodiment of the present application, an auxiliary rotating unit is arranged on the outer wall of each connecting pipe 15, and is used to drive the corresponding air outlet pipe 2 to rotate. The auxiliary rotating unit comprises a baffle 21 and an auxiliary ring plate 22. An auxiliary ring plate 22 is arranged on the bottom end of the outer wall of each connecting pipe 15. A plurality of air outlet channels 23 are evenly arranged on the circumferential direction of each connecting pipe 15 and auxiliary ring plate 22. That is, a plurality of air outlet channels 23 are evenly arranged on each connecting pipe 15 and auxiliary ring plate 22. One section of the air outlet channel 23 is a horizontal channel 24 perpendicular to the axial direction of the connecting pipe 15. Each horizontal channel 24 is in communication with the corresponding connecting pipe 15. Another section of the air outlet channel 23 is a vertical channel 25 parallel to the axial direction of the connecting pipe 15. The end of each vertical channel 25 is connected with a nozzle 26. A sliding groove 27 is arranged in the middle of each vertical channel 25. A baffle 21 is slidingly and sealingly arranged in each sliding groove 27. A through hole 28 is arranged on each baffle 21. Each through hole 28 is arranged corresponding to the corresponding vertical channel 25. The baffle 21 and the inner wall of the corresponding sliding groove 27 are connected by a third elastic member 29. The top end of each air outlet pipe 2 is in a funnel structure. The radius of the funnel structure of the top end of each air outlet pipe 2 gradually decreases from the top end to the bottom end. The funnel structure of the top end of each air outlet pipe 2 is wedge-shaped matched with the corresponding baffle 21. A clamping plate 30 is arranged at the inner end of each baffle 21. A driven ring plate 31 is arranged on the outer wall of the bottom end of the funnel structure of each air outlet pipe 2. A plurality of driven plates 32 are evenly arranged on the top end of each driven ring plate 31 in the circumferential direction. That is, a plurality of driven plates 32 are arranged on each driven ring plate 31 in the circumferential direction. Each driven plate 32 is used in cooperation with the corresponding nozzle 26.

[0041] Specifically, when the gas does not enter into the connecting pipe 15, the third elastic member 29 (the third elastic member 29 is an element capable of elastic reset, preferably a spring) provides a certain elastic force for the baffle 21, so that the baffle 21 performs the closing operation on the vertical channel 25, that is, at this time, the communication hole 28 on the baffle 21 is misaligned with the vertical channel 25, so that the baffle 21 can perform the closing operation on the vertical channel 25, so that the gas cannot be discharged from the vertical channel 25 to the gas outlet pipe 2. When the gas is transported in the connecting pipe 15 to the gas outlet pipe 2, the top end of the gas outlet pipe 2 is a funnel-shaped structure, and the radius of the funnel-shaped structure gradually decreases from the top end to the bottom end, so that when the gas enters the gas outlet pipe 2 from the connecting pipe 15, the gas passes through the funnel-shaped structure at the top end of the gas outlet pipe 2, so that the flow rate of the gas increases (due to the action of the law of conservation of mass, the flow of the gas remains unchanged, however, at the bottom end of the funnel-shaped structure, due to the smaller area, the flow velocity of the gas increases), the gas outlet pipe 2 is subjected to the blowing force of the gas and its own gravity, and the gas outlet pipe 2 slides in the connecting pipe 15 to form a terminal end, and the flow rate of the gas in the gas outlet pipe 2 increases. When the gas outlet pipe 2 moves in the connecting pipe 15 to form a terminal end, the top end of the gas outlet pipe 2 is a funnel-shaped structure, and the funnel-shaped structure at the top end of the gas outlet pipe 2 is wedge-shaped with the baffle 21, so that the funnel-shaped structure at the top end of the gas outlet pipe 2 pushes the baffle 21 to slide to the inside of the sliding groove 27. The end until the funnel-shaped structure at the top end of the gas outlet pipe 2 slides to the position of the clamping plate 30, at this time, the communication hole 28 on the baffle 21 is communicated with the vertical channel 25, so that the gas can be discharged from the gas outlet channel 23 and the nozzle 26, so that the gas in the nozzle 26 acts on the driven plate 32, so that the driven plate 32 drives the driven ring plate 31 to rotate, and the driven ring plate 31 drives the gas outlet pipe 2 to rotate (since the reset ring 19 is rotationally arranged in the connecting pipe 15, the rotation of the driven plate 32 and the gas outlet pipe 2 will not be affected by the reset ring 19. In this embodiment, the second elastic member 20 is a spring, so that the gas outlet pipe 2 can drive the reset ring 19 to rotate in the connecting pipe 15 through the second elastic member 20, and the second elastic member 20 will not block the gas outlet channel 23). The gas outlet pipe 2 rotates at the same time to release micro-bubbles, so that the micro-bubbles released in the gas outlet pipe 2 have a certain rotational initial speed, so that the micro-bubbles released in the gas outlet pipe 2 can rotate to a certain extent, and the range of movement of the micro-bubbles during rotation is increased, thereby improving the ice prevention effect of the bubbles.

[0042] As another embodiment of the present application, preferably, an auxiliary groove 33 is formed in the outer wall of each driven plate 32, and a driven member 34 is slidably installed in each auxiliary groove 33. Each driven member 34 is connected to the inner wall of the auxiliary groove 33 through a fourth elastic member 35, and each driven member 34 is located inside the auxiliary groove 33 under the pulling action of the fourth elastic member 35.

[0043] Specifically, when the air outlet pipe 2 and the driven plate 32 rotate, the air outlet pipe 2 drives the driven member 34 in the auxiliary groove 33 to rotate, so that the driven member 34 is subjected to the centrifugal force when rotating, the driven member 34 slides from the inside of the auxiliary groove 33 to the outside, the driven member 34 slides to the outside of the auxiliary groove 33, the driven member 34 provides a certain tension to the fourth elastic member 35 (the fourth elastic member 35 is an element capable of elastic reset, preferably a spring), so that the fourth elastic member 35 is in a stretched state, the stress surface of the driven plate 32 subjected to the jet force of the jet pipe 26 is increased, so that the jet force of the jet pipe 26 on the driven plate 32 and the driven member 34 is increased, thereby increasing the rotation speed of the driven plate 32 and the air outlet pipe 2, the initial rotation speed of the micro-bubbles released in the air outlet pipe 2 is increased while the rotation speed of the air outlet pipe 2 is increased, so that the movement range of the micro-bubbles is increased, the bubble anti-icing effect is improved, and through the rotation of the air outlet pipe 2 in the water body, the probability of clogging of the air outlet pipe 2 can be greatly reduced. Even if the air outlet pipe 2 is clogged in the water body, the clogging material at the clogging position of the air outlet pipe 2 can be thrown out of the air outlet pipe 2 through the centrifugal force generated when the air outlet pipe 2 rotates, further reducing the probability of clogging of the air outlet pipe 2.

[0044] As another embodiment of the present application, preferably, the bottom end of each air outlet pipe 2 is provided with a liquid stirring disc 36, and a plurality of circular arc plates 37 are uniformly arranged on the liquid stirring disc 36 in the circumferential direction.

[0045] Specifically, when the air outlet pipe 2 rotates, the air outlet pipe 2 drives the liquid stirring disc 36 to rotate, the liquid stirring disc 36 drives the circular arc plate 37 to rotate, and when the circular arc plate 37 rotates in the water body, the circular arc plate 37 can drive the water flow to form a vortex, so that the vortex drives the micro-bubbles released in the air outlet pipe 2 to move to the water surface, effectively preventing the water surface from icing, and the vortex formed by the rotation of the circular arc plate 37 can prevent the water bottom from icing, effectively preventing the water bottom and the water surface from icing.

[0046] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
