[0037] When ice-melting and anti-icing measures are needed for the water-approaching side of the hyperbolic arch dam body 1 in winter, the PLC controller 5 controls the aeration anti-icing structure 3 to work, so that the air pump 38 on the right side in the aeration anti-icing structure 3 works, since the heat exchange pipe one 32 and the heat exchange pipe two 33 are fixedly connected inside the heat preservation tower 31, the connection pipe one 34 is fixedly connected between the heat exchange pipe one 32 and the heat exchange pipe two 33, the heat exchange pipe one 32, the heat exchange pipe two 33 and the connection pipe one 34 form a heat exchange pipe, and the connection pipe five 320 is fixedly connected to one end of the heat exchange pipe two 33, the three-way valve 36 is fixedly connected to one end of the connection pipe five 320, and the air pump 38 fixedly connected to the always open end of the three-way valve 36 works at this time, so the air pump 38 on the right side draws air through the three-way valve 36, the connection pipe five 320 and the heat exchange pipe, and the connection pipe two 37 fixedly connected to the always closed end of the three-way valve 36 is fixedly connected to the air pump 38 on the left side of the top of the hyperbolic arch dam body 1; therefore, after the always closed end of the three-way valve 36 is opened by controlling, the air pump 38 on the left side draws air through the connection pipe two 37, the three-way valve 36, the connection pipe five 320 and the heat exchange pipe; and the connection pipe three 39 is fixedly connected to the air outlet end of each of the two air pumps 38, and the two connection pipes three 39 are respectively fixedly connected to the two connection tubes four 310 arranged on the two sides of the hyperbolic arch dam body 1, so the two connection pipes three 39 installed on the air outlet ends of the left and right air pumps 38 are in communication with the arc-shaped air guide pipe structure, in the case of uninterrupted air supply to the inside of the arc-shaped air guide pipe structure, the two air pumps 38 can be alternately controlled to work, which not only meets the ice-melting and anti-icing work of the water-approaching side of the hyperbolic arch dam body 1, but also allows the air pump 38 to have sufficient rest, reduces the possibility of "burning out" damage due to long working time of the air pump 38, and ensures the stability of the work of the aeration anti-icing structure 3;

[0038] After the gas enters the arc-shaped air guide pipe structure, the multiple pressure relief valves 312 are fixedly connected to the outer bottom of the multiple connecting pipes four 310, the bubble generator 311 is fixedly connected to the bottom of the pressure relief valve 312, and finally the airflow breaks through the pressure relief valve 312 and is discharged through the bubble generator 311 as the air pressure in the connecting pipe four 310 increases, a large amount of bubbles are produced, and the bubbles agitate the water surface during movement to the water surface, thereby preventing the water surface from freezing.

[0039] When the air pump 38 is controlled to work, the multiple heating wires 35 fixedly connected to the inside of the heat preservation tower 31 are controlled to work, the working heating wires 35 heat the liquid in the inside of the heat preservation tower 31, the heat exchange pipe one 32 and the heat exchange pipe two 33 are both spirally arranged, so that the heat exchange pipe one 32 and the heat exchange pipe two 33 have sufficient contact area with the liquid in the inside of the heat preservation tower 31, the multiple heating wires 35 are arranged in the inside and the outside of the heat exchange pipe one 32, and the heating effect of the heat exchange pipe one 32 on the airflow in the inside is further increased, and the bottom end of the heat exchange pipe one 32 extends to the bottom outside of the heat preservation tower 31, so that when the air pump 38 draws air from the outside of the heat preservation tower 31 through the connecting pipe two 37, the three-way valve 36, the connecting pipe five 320 and the heat exchange pipe, the airflow is heated after passing through the inside of the heat preservation tower 31, the bubbles agitating the water surface are generated from the high-temperature gas, and the ice melting and ice preventing effect is improved.

[0040] The temperature sensor 6 arranged on the equipment shell 21 is electrically connected to the PLC controller 5, the temperature sensor 6 is used for detecting the ambient temperature, the PLC controller 5 can store the control program edited in advance in the inside, the PLC controller 5 controls the aeration ice preventing structure 3 to work according to the temperature value detected by the temperature sensor 6, when the temperature value fed back to the PLC controller 5 by the temperature sensor 6 is 5°-3° below zero, the PLC controller 5 controls the two air pumps 38 and the three-way valve 36 in the aeration ice preventing structure 3 to work, the water surface is disturbed, and the water side of the double-curvature arch dam body 1 is prevented from freezing; when the temperature value fed back to the PLC controller 5 by the temperature sensor 6 is 3° below zero-10° below zero, the PLC controller 5 controls the two air pumps 38 and the three-way valve 36 in the aeration ice preventing structure 3 to work while controlling the multiple heating wires 35 to work at low power; when the temperature value fed back to the PLC controller 5 by the temperature sensor 6 is below 10° below zero, the PLC controller 5 controls the two air pumps 38 and the three-way valve 36 in the aeration ice preventing structure 3 to work while controlling the multiple heating wires 35 to work at full power, so that the aeration ice melting and ice preventing equipment composed of the lifting structure 2 and the aeration ice preventing structure 3 works efficiently according to the external temperature, and resource waste is reduced.

[0041] When the PLC controller 5 controls the aeration anti-icing structure 3 to work, the hoisting structure 2 can be controlled to work synchronously, at this time, the positive and negative motor 28 fixedly installed in the equipment shell 21 in the hoisting structure 2 works, the positive and negative motor 28 alternately works in the positive rotation and the reverse rotation, when the positive and negative motor 28 works in the positive rotation or the reverse rotation, the transmission shaft I 29 fixedly connected to the output end of the positive and negative motor 28 rotates, so that the transmission shaft I 29 rotates in the equipment shell 21, and the winding frame 211 fixedly sleeved on the outer side of the transmission shaft I 29 rotates, since the pull rope 22 is fixedly connected to the winding frame 211 and the support frame I 23 at both ends respectively, when the positive and negative motor 28 works in the positive rotation or the reverse rotation, the winding frame 211 winds the pull rope 22 in the positive rotation or unwinds the pull rope 22 in the reverse rotation, so that the pull rope 22 drives the support frame I 23 to move up and down, since the two guide rail frames I 24 slidingly connected to the support frame I 23 are fixedly installed on the double-curvature arch dam body 1 to limit and guide the up and down movement of the support frame I 23, the support frame I 23 can only move up and down;

[0042] Moreover, the support frame I 23 is fixedly connected with a plurality of electromagnets 25, the plurality of electromagnets 25 are sleeved on the outer sides of the plurality of pressure relief valves 312 respectively, the plurality of electromagnets 25 are fixedly attracted to the outer sides of the pressure relief valves 312 through magnetic force in the working state, so that the relative positions between the connecting pipe IV 310 installed on the pressure relief valve 312 and the support frame I 23 fixedly connected with the electromagnets 25 remain unchanged, so that the support frame I 23 drives the plurality of connecting pipe IV 310 to move up and down when the support frame I 23 moves up and down, and the connecting pipe III 39 can be telescopic to meet the needs of the up and down movement of the connecting pipe IV 310, so that the connecting pipe IV 310 can move up and down, the distance between the bubble generator 311 and the water surface is controlled, the bubble generator 311 can move up and down in a certain range, the water area is disturbed, and the effect of disturbing the water surface is increased.

[0043] Moreover, the liquid level sensor 7 is electrically connected with the PLC controller 5, the liquid level sensor 7 is used to detect the liquid level height of the water surface, the PLC controller 5 controls the hoisting structure 2 to work according to the liquid level height value detected by the liquid level sensor 7, so that the initial height of the arc-shaped air guide pipeline structure composed of the plurality of connecting pipe IV 310 is controlled by the hoisting structure 2, the situation that the arc-shaped air guide pipeline structure is frozen because the distance between the arc-shaped air guide pipeline structure and the water surface is too close is avoided, the position of the arc-shaped air guide pipeline structure changes according to the liquid level height of the water surface, and the hoisting structure 2 can stably disturb the water surface to avoid icing.

[0044] In addition, as Figure 2 , Figure 9 and Figure 10As shown, when the arc-shaped air duct structure height adjustment is completed and does not need to be worked, does not need to make the arc-shaped air duct structure composed of multiple connecting pipes 310 to move up and down to disturb the water area and the forward and reverse motor 28 needs to rest for a period of time, the PLC controller 5 controls the lifting structure 2 to transport the arc-shaped air duct structure to the appropriate height, then controls the two brakes 210 outside the transmission shaft one 29 to work, and the brakes 210 fixedly installed inside the equipment shell 21 work to stop the transmission shaft one 29, so that the rotation of the transmission shaft one 29 is limited. At this time, the arc-shaped air duct structure controlled by the transmission shaft one 29, the winding frame 211, the pull rope 22 and the support frame one 23 is stably stopped in place, so that the forward and reverse motor 28 stops working and enters the resting state, and does not affect the effect of disturbing the water surface by the arc-shaped air duct structure.

[0045] In addition, as shown in Figure 9 , Figure 10 , Figure 11 and Figure 12 , during the winding of the pull rope 22, the pull rope 22 penetrates the cleaning piece 213 in the direction-changing cleaning structure, the cleaning piece 213 cleans the outside of the pull rope 22, avoids the garbage and impurities outside the pull rope 22 from entering the inside of the equipment shell 21, ensures the cleanliness of the inside of the equipment shell 21, and ensures the service life of the equipment inside the equipment shell 21.

[0046] The direction-changing cleaning structure is provided with two support frames five 217 fixedly connected to the bottom of the equipment shell 21, a lead screw 216 is rotatably connected between the two support frames five 217, chain wheels 219 are fixedly sleeved outside the lead screw 216 and the transmission shaft one 29, and chains 220 are sleeved outside the two chain wheels 219. Under the transmission of the chains 220 and the two chain wheels 219, the transmission shaft one 29 drives the lead screw 216 to rotate, the rotating lead screw 216 drives the sliding block 215 sleeved outside through the nut pair, the sliding block 215 is limited in sliding connection with the guide rail frame two 218, so that the sliding block 215 can only move horizontally reciprocatingly outside the lead screw 216, one side of the reciprocating sliding block 215 is fixedly connected with the support frame four 214, the support frame three 212 fixedly connected with the support frame four 214 is fixedly connected with the cleaning piece 213, and the pull rope 22 penetrates the support frame three 212 and the cleaning piece 213. Therefore, when the sliding block 215 drives the support frame three 212 and the cleaning piece 213 to move outside through the support frame four 214, a reciprocating force is applied to the winding position of the pull rope 22 by the winding frame 211, so that the pull rope 22 is uniformly arranged and wound outside the winding frame 211, and the possibility of knotting of the pull rope 22 is reduced.

[0047] In addition, as shown in Figure 7 and Figure 8 and Figure 12As shown, the connection structure 4 is provided with a splicing pipe three 43 inside the splicing pipe one 41 and the splicing pipe two 42, and the splicing pipe one 41 and the splicing pipe two 42 are fixedly connected with the adjacent connection pipe four 310 at the ends away from each other, the two splicing pipe one 41 are adhered together, and the two adjacent connection pipe four 310 are butted together; and the two splicing pipe three 43 are provided with spring telescopic rods 47 on the sides away from each other, a plurality of fixed racks two 49 are fixedly connected on the outer wall of the spring telescopic rod 47, and a sealing circular plate 46 is fixedly connected between the plurality of fixed racks two 49. Since the outer wall of the spring telescopic rod 47 is fixedly connected with the connection pipe four 310 through the plurality of fixed racks one 48, the relative position between the sealing circular plate 46 and the outer wall of the spring telescopic rod 47 remains unchanged; a plurality of fixed racks four 411 are fixedly connected with the adjacent splicing pipe three 43 at one end, and the fixed rack three 410 fixedly connected between the plurality of fixed racks four 411 is fixedly connected with the piston end of the adjacent spring telescopic rod 47. In the case that the spring telescopic rod 47 can be telescopic, the relative position between the splicing pipe three 43 and the splicing pipe one 41 can be changed.

[0048] When there is no gas flow injected into the arc-shaped air guide pipe structure, the piston end of the plurality of spring telescopic rods 47 is partially extended in the initial position, and the two splicing pipe three 43 are in the initial position. At this time, the two splicing pipe three 43 are located outside the two sealing circular plates 46 to form a sealing structure, so that the two connection pipe four 310 are in a sealed state, and the splicing pipe one 41 and the splicing pipe two 42 are not blocked. Therefore, at this time, the plurality of electromagnets 25 are controlled to stop working, so that the pressure relief valve 312 fixedly connected with the connection pipe four 310 loses the fixation, that is, the connection pipe four 310 loses the fixation, and a tool can be used to hook the hook 313 fixedly connected to the top of the connection pipe four 310 to pull up the connection pipe four 310 for maintenance and repair of the plurality of pressure relief valves 312 and the bubble generator 311 fixedly connected to the connection pipe four 310. The plurality of connection pipe four 310 can be repaired in sections, the required space is small, the one-time workload is small, and the situation that the entire arc-shaped air guide pipe structure needs to be replaced due to local damage is avoided.

[0049] When the gas is poured into the arc-shaped air guide pipe structure, the airflow enters the arc-shaped air guide pipe structure from the connecting pipe four 310 close to the connecting pipe three 39, and acts on the plurality of connecting structures 4 in turn. After the airflow enters the inside of the connecting pipe four 310, it will push the splicing pipe three 43 arranged on one side of the inside of the connecting pipe four 310 to move. The inner wall of the splicing pipe three 43 is arranged in a stepped shape, and a small part of the inner diameter of the splicing pipe three 43 is the same as the outer diameter of the sealing circular plate 46. When the splicing pipe three 43 cooperates with the sealing circular plate 46 to block one end of the connecting pipe four 310, most of the inner diameter of the splicing pipe three 43 is larger than the outer diameter of the sealing circular plate 46. After the splicing pipe three 43 moves a small distance, the cooperation and sealing state between the splicing pipe three 43 and the sealing circular plate 46 can be removed. The splicing pipe three 43 that moves pushes the adjacent splicing pipe three 43 to move, so that it also moves away from the outside of the sealing circular plate 46 inside. At this time, the two connecting pipe fours 310 are connected.

[0050] And no matter whether the left or right air pump 38 works, the working state of the connecting structure 4 will change, and the plurality of connecting pipe fours 310 will be connected. After the working state of the connecting structure 4 changes, one splicing pipe three 43 will move to the interface between the splicing pipe one 41 and the splicing pipe two 42 at the bottom, and the outer diameter of the splicing pipe three 43 is the same as the inner diameter of the splicing pipe one 41 and the splicing pipe two 42. Therefore, after the working state of the connecting structure 4 changes, the splicing pipe three 43 plays a role in sealing the state between the splicing pipe one 41 and the splicing pipe two 42, ensuring the sealing performance of the airflow flowing in the arc-shaped air guide pipe structure through the quality of the bubble generation.

[0051] A plurality of annular grooves 44 are arranged on one side of the splicing pipe three 43 away from the spring type telescopic rod 47, and a plurality of plug-in plates 45 are fixedly connected to the other side of the splicing pipe three 43 away from the spring type telescopic rod 47. After the splicing pipe three 43 moves, the plug-in plate 45 will enter the inside of the annular groove 44, so that the two splicing pipes three 43 are clamped together. One of the splicing pipes three 43 is arranged inside the contact position between the splicing pipe one 41 and the splicing pipe two 42 to support the splicing pipe one 41 and the splicing pipe two 42, further increasing the stability between the two connecting pipe fours 310.

[0052] In addition, such as Figure 2 and Figure 4As shown, the conical gear one 314 is rotatably connected to the top of the heat preservation tower 31, the conical gear two 316 is engaged with the conical gear one 314, the hand wheel 315 fixedly connected inside the conical gear two 316 is rotated, the hand wheel 315 is rotated on one side of the heat preservation tower 31, the hand wheel 315 drives the conical gear two 316 to rotate, the rotating conical gear two 316 drives the conical gear one 314 to rotate, and the conical gear one 314 is fixedly connected with the support frame six 318, so that the conical gear one 314 drives the support frame six 318 to rotate, the support frame six 318 rotatably connected to the top of the heat preservation tower 31 is rotated, and the bolt 319 screwedly connected with the support frame six 318 is fixedly connected with the liquid level sensor 7, so that the liquid level sensor 7 is rotated to the top of the double-curvature arch dam body 1, and the liquid level sensor 7 installed through the threaded structure can be quickly disassembled, so that the liquid level sensor 7 is conveniently and quickly checked and maintained.

[0053] The limiting vertical plate 317 is fixedly connected to the top of the heat preservation tower 31, the limiting vertical plate 317 blocks the position of the support frame six 318, and after the support frame six 318 is driven to rotate clockwise to rotate the liquid level sensor 7 above the water surface, the movement of the support frame six 318 is limited by the limiting vertical plate 317.

[0054] In addition, as shown in the drawings, Figure 11 The support frame two 26 is fixedly connected to the side, away from the double-curvature arch dam body 1, of the support frame one 23, and the metal mesh 27 is fixedly connected to one end of the support frame two 26, after the support frame six 318 is blocked by the limiting vertical plate 317 to move clockwise, the liquid level sensor 7 stays on the top of the metal mesh 27, the metal mesh 27 blocks the garbage and impurities outside, so that the water level inside the metal mesh 27 is not affected by the floating objects, and the liquid level sensor 7 can accurately detect the water level height.

[0055] In addition, as shown in the drawings, Figure 9 The long slot 221 is formed in the bottom of the equipment shell 21, the top end of the pull rope 22 penetrates through the long slot 221 and enters the inside of the equipment shell 21, and the long slot 221 provides space for the partial reciprocating movement of the pull rope 22.
