Description

Technical Field

[0002] With the advancement of hydropower development technology, hydropower station projects can also be built in high-altitude cold areas (high-altitude cold areas or high-latitude cold areas). However, when the dam is located in a high-altitude cold area, the dam operating environment is extremely harsh, and the difference between extreme low and high temperatures in a year can even exceed 80°C.

[0003] In order to prevent temperature cracks in concrete dams and damage from freeze-thaw cycles in low temperature environments, a common practice is to install an insulation layer on the dam surface. During winter operation, after the reservoir freezes, the water level below the ice surface will change due to factors such as power generation at the power station and temperature changes, causing the ice layer to move upward or downward. The ice layer of the reservoir is bonded to the insulation layer on the surface of the dam, and the displacement of the ice layer may cause ice pull damage to the insulation layer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present application, a plurality of connecting pipes four and a plurality of connecting structures form an arc-shaped air guide duct structure with the same curvature as that of the water-facing side of the hyperbolic arch dam body. After the gas enters the arc-shaped air guide duct structure, since a plurality of pressure relief valves are fixedly connected to the bottom of the outer sides of the plurality of connecting pipes four, a bubble generator is fixedly connected to the bottom of the pressure relief valve. As the air pressure inside the connecting pipe four increases, the airflow eventually breaks through the pressure relief valve and is discharged through the bubble generator, producing a large number of bubbles. During the movement of the bubbles toward the water surface, the water surface is stirred to prevent the water surface from freezing, thereby comprehensively preventing the water-facing side of the hyperbolic arch dam body from freezing and reducing the damage to the water-facing side structure of the hyperbolic arch dam body caused by freezing.

[0017] 2. The present application can work by alternately controlling the two air pumps, which can satisfy the ice melting and anti-icing work on the water-facing side of the hyperbolic arch dam body, and can also allow the air pump to get sufficient rest, reduce the possibility of "burning" and damage of the air pump due to long working time, and ensure the stability of the aeration anti-icing structure. As the air pressure inside the connecting pipe four increases, the airflow eventually breaks through the pressure relief valve and is discharged through the bubble generator, generating a large number of bubbles. During the movement of the bubbles to the water surface, the water surface is stirred to prevent the water surface from freezing. When the air pump draws air from the outside of the insulation tower through the connecting pipe two, the three-way valve, the connecting pipe five, the heat exchange pipe and other structures, the airflow is heated after passing through the inside of the insulation tower, so that the bubbles stirring the water surface are generated by high-temperature gas, thereby improving the ice melting and anti-icing effect.

[0018] 3. In the present application, the temperature sensor installed on the equipment casing is electrically connected to the PLC controller. The temperature sensor is used to detect the ambient temperature. The control program edited in advance can be stored inside the PLC controller. The PLC controller controls the aeration anti-icing structure to work according to the temperature value detected by the temperature sensor, so that the aeration ice-melting and anti-icing equipment composed of the lifting structure and the aeration anti-icing structure can work efficiently according to the outside temperature and reduce resource waste.

[0019] 4. In the present application, when the PLC controller controls the operation of the aeration anti-icing structure, it can synchronously control the operation of the lifting structure, so that the connecting pipe four moves up and down, controls the position of the bubble generator from the water surface, and makes the bubble generator move up and down within a certain range, thereby disturbing the water area and increasing the effect of disturbing the water surface; the PLC controller controls the operation of the lifting structure according to the liquid level height value detected by the liquid level sensor, so that the lifting structure controls the initial height of the arc-shaped air guide duct structure composed of multiple connecting pipes four, thereby avoiding the situation where the arc-shaped air guide duct structure is too close to the water surface and is frozen, and the arc-shaped air guide duct structure and position are changed according to the water surface liquid level height, thereby ensuring that the aeration anti-icing structure stably disturbs the water surface and avoids ice formation.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example: Figure 1 - Fig.13As shown, the present invention provides a technical solution for an aeration ice-melting and ice-proofing device for a hyperbolic arch dam in a high-cold region. A lifting structure 2, an aeration and ice-proofing structure 3, a PLC controller 5, a temperature sensor 6 and a liquid level sensor 7 are arranged on the outer convex surface side of a hyperbolic arch dam body 1.

[0036] An aeration anti-icing structure 3 for generating bubbles to disturb the water surface is installed on the hyperbolic arch dam body 1. In the aeration anti-icing structure 3, multiple connecting pipes 4 310 are arranged on the outer convex curved surface side of the hyperbolic arch dam body 1. In this case, multiple connecting pipes 4 310 are arranged on the water-facing direction of the hyperbolic arch dam body 1, and a connecting structure 4 is arranged between two adjacent connecting pipes 4 310. Multiple connecting structures 4 install multiple connecting pipes 4 310 together. Multiple connecting pipes 4 310 and multiple connecting structures 4 form an arc-shaped air guide pipe structure with the same curvature as the water-facing side of the hyperbolic arch dam body 1, thereby ensuring a comprehensive anti-freezing effect on the water-facing side of the hyperbolic arch dam body 1 and reducing the damage of ice to the water-facing side structure of the hyperbolic arch dam body 1;

[0037] When it is necessary to take ice-melting and ice-proof measures on the water-facing side of the hyperbolic arch dam body 1 in winter, the aeration anti-icing structure 3 is controlled by the PLC controller 5 to work, so that the air pump 38 located on the right side of the aeration anti-icing structure 3 works. Since the heat exchange tube 1 32 and the heat exchange tube 2 33 are fixedly connected inside the insulation tower 31, and the connecting tube 1 34 is fixedly connected between the heat exchange tube 1 32 and the heat exchange tube 2 33, the heat exchange tube 1 32, the heat exchange tube 2 33 and the connecting tube 1 34 constitute a heat exchange pipeline, and the heat exchange tube 2 33 is fixedly connected to the connecting tube 5 320 at one end, and the connecting tube 5 320 is fixedly connected to the three-way valve 36 at one end. The air pump 38 fixedly connected to the normally open end of the three-way valve 36 works at this time, so the air pump 38 on the right side exhausts air through the three-way valve 36, the connecting tube 5 320, and the heat exchange pipeline, and the connecting tube 2 37 fixedly connected to the normally closed end of the three-way valve 36 is connected to the left side of the top of the hyperbolic arch dam body 1 The air pump 38 on the left and right sides is fixedly connected; so after the normally closed end of the three-way valve 36 is opened, the air pump 38 on the left side is exhausted through the connecting pipe 2 37, the three-way valve 36, the connecting pipe 5 320, and the heat exchange pipe; and the air outlet ends of the two air pumps 38 are fixedly connected with the connecting pipe 3 39, and the two connecting pipes 39 are respectively fixedly connected to the two connecting pipes 4 310 arranged on both sides of the hyperbolic arch dam body 1, so the two connecting pipes 39 installed at the air outlet ends of the left and right air pumps 38 are connected to the arc-shaped air guide pipe structure. Under the condition of uninterrupted air supply to the inside of the arc-shaped air guide pipe structure, the two air pumps 38 can be controlled alternately to work, that is, the ice melting and ice prevention work on the water-facing side of the hyperbolic arch dam body 1 is met, and the air pump 38 can also get a full rest, reducing the possibility of the air pump 38 being "burned" and damaged due to working for too long, and ensuring the stability of the aeration and ice prevention structure 3.

[0038] After the gas enters the arc-shaped air guide duct structure, since multiple pressure relief valves 312 are fixedly connected to the bottom of the outer sides of the multiple connecting pipes four 310, and a bubble generator 311 is fixedly connected to the bottom of the pressure relief valve 312, as the air pressure inside the connecting pipe four 310 increases, the airflow eventually breaks through the pressure relief valve 312 and is discharged through the bubble generator 311, producing a large number of bubbles. During the movement of the bubbles toward the water surface, the water surface is stirred to prevent the water surface from freezing.

[0039] When the air pump 38 is controlled to work, the multiple heating wires 35 fixedly connected inside the insulation tower 31 can be controlled to work. The working heating wires 35 heat the liquid inside the insulation tower 31. The heat exchange tube 1 32 and the heat exchange tube 2 33 are both configured as spiral pipes, so the heat exchange tube 1 32 and the heat exchange tube 2 33 have sufficient contact area with the liquid inside the insulation tower 31. The multiple heating wires 35 are respectively arranged inside and outside the heat exchange tube 1 32, further increasing the effect of the heat exchange tube 1 32 being heated by the airflow. The bottom end of the heat exchange tube 1 32 extends to the bottom of the outside of the insulation tower 31, so when the air pump 38 draws air from the outside of the insulation tower 31 through the connecting tube 2 37, the three-way valve 36, the connecting tube 5 320, the heat exchange pipe and other structures, the airflow is heated after passing through the inside of the insulation tower 31, so that the bubbles that stir the water surface are generated by the high-temperature gas, thereby improving the ice melting and anti-icing effect.

[0040] And the temperature sensor 6 installed on the equipment housing 21 is electrically connected to the PLC controller 5. The temperature sensor 6 is used to detect the ambient temperature. The control program edited in advance can be stored in the PLC controller 5. The PLC controller 5 controls the aeration and ice protection 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 between 5° and minus 3°, the PLC controller 5 controls the two air pumps 38 and the three-way valve 36 in the aeration and ice protection structure 3 to work, disturb the water surface, and avoid ice on the waterside of the hyperbolic arch dam body 1; when the temperature sensor 6 feeds back to the PLC controller 5, the water surface is disturbed, and ice is prevented from forming on the waterside of the hyperbolic arch dam body 1; when the temperature sensor 6 feeds back to the When the temperature value of the PLC controller 5 is between minus 3° and minus 10°, the PLC controller 5 controls the two air pumps 38 and the three-way valve 36 in the aeration anti-icing structure 3 to work, and controls 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 minus 10°, the PLC controller 5 controls the two air pumps 38 and the three-way valve 36 in the aeration anti-icing structure 3 to work, and controls the multiple heating wires 35 to work at full power, so that the aeration ice-melting and anti-icing equipment composed of the lifting structure 2 and the aeration anti-icing structure 3 can work efficiently according to the outside temperature, reducing resource waste.

[0041] When the PLC controller 5 controls the aeration and ice protection structure 3 to work, the lifting structure 2 can be controlled to work synchronously. At this time, the forward and reverse motor 28 fixedly installed inside the equipment housing 21 of the lifting structure 2 works, and the forward and reverse motor 28 alternately works forward and reverse. When the forward and reverse motor 28 works forward or reverse, the transmission shaft 29 fixedly connected to the output end of the forward and reverse motor 28 rotates, so that the transmission shaft 29 rotates inside the equipment housing 21, and the winding frame 211 fixedly sleeved on the outer side of the transmission shaft 29 rotates. Since the two ends of the pull rope 22 are respectively fixedly connected to the winding frame 211 and the support frame 23; therefore, when the forward and reverse motor 28 works forward or reverse, the winding frame 211 rotates forward to rewind the pull rope 22 or reversely unwinds the pull rope 22, so that the pull rope 22 drives the support frame 23 to move up and down, because the two guide rail frames 24 slidingly connected to the support frame 23 are fixedly installed on the hyperbolic arch dam body 1 to limit and guide the up and down movement of the support frame 23, so that the support frame 23 can only move up and down;

[0042] In addition, the support frame 23 is fixedly connected to a plurality of electromagnets 25, and the plurality of electromagnets 25 are respectively sleeved on the outside of a plurality of pressure relief valves 312. The plurality of electromagnets 25 are in a working state and are fixed to the outside of the pressure relief valve 312 by magnetic adsorption, so that the relative position between the connecting pipe four 310 installed on the pressure relief valve 312 and the support frame 23 fixed with the electromagnet 25 remains unchanged. Therefore, when the support frame 23 moves up and down, the plurality of connecting pipes four 310 are driven to move up and down, and the connecting pipe three 39 can be extended and retracted to meet the needs of the up and down movement of the connecting pipe four 310, so that the connecting pipe four 310 can be moved up and down, and the position of the bubble generator 311 from the water surface can be controlled, so that the bubble generator 311 can move up and down within a certain range, disturb the water area, and increase the effect of disturbing the water surface.

[0043] In addition, the liquid level sensor 7 is electrically connected to the PLC controller 5. The liquid level sensor 7 is used to detect the height of the liquid level on the water surface. The PLC controller 5 controls the operation of the lifting structure 2 according to the liquid level height value detected by the liquid level sensor 7, so that the lifting structure 2 controls the initial height of the arc-shaped air guide duct structure composed of multiple connecting pipes 4 310, thereby avoiding the situation where the arc-shaped air guide duct structure is too close to the water surface and is frozen, and the arc-shaped air guide duct structure and position are changed according to the height of the liquid level on the water surface, thereby ensuring that the aeration and anti-icing structure 3 stably disturbs the water surface to avoid freezing.

[0044] In addition, such as Figure 2 , Fig. 9 and Fig.10As shown, when the height of the arc-shaped air-guiding duct structure is adjusted and there is no need to work, there is no need to make the arc-shaped air-guiding duct structure composed of multiple connecting pipes 4 310 move up and down to disturb the water area, and the forward and reverse motors 28 need to rest after working for a period of time, the PLC controller 5 controls the lifting structure 2 to transport the arc-shaped air-guiding duct structure to a suitable height, controls the two brakes 210 sleeved on the outside of the transmission shaft 1 29 to work, and the brake 210 fixedly installed inside the equipment housing 21 works to stop the transmission shaft 1 29, so that the rotation of the transmission shaft 1 29 is restricted. At this time, the arc-shaped air-guiding duct structure whose height is controlled by the transmission shaft 1 29, the winding frame 211, the pull rope 22 and the support frame 1 23 stays stably in place, so that the forward and reverse motors 28 stop working and enter a rest state, and does not affect the effect of the arc-shaped air-guiding duct structure on the disturbance of the water surface.

[0045] In addition, such as Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, during the process of the pull rope 22 being rolled up, the pull rope 22 passes through the cleaning member 213 in the redirecting cleaning structure, and the cleaning member 213 cleans the outside of the pull rope 22 to prevent garbage and impurities on the outside of the pull rope 22 from entering the inside of the device housing 21, thereby ensuring the cleanliness of the inside of the device housing 21 and the service life of the equipment inside the device housing 21;

[0046] The reversing cleaning structure is provided with two support frames 5 217 fixedly connected to the bottom of the equipment housing 21, a screw rod 216 is rotatably connected between the two support frames 5 217, and a sprocket 219 is fixedly sleeved on the outside of the screw rod 216 and the transmission shaft 1 29, and a chain 220 is sleeved on the outside of the two sprockets 219. Under the transmission action of the chain 220 and the two sprockets 219, the transmission shaft 1 29 rotates to drive the screw rod 216 to rotate, and the rotating screw rod 216 drives the sliding block 215 sleeved on the outside through the nut pair. Since the guide rail frame 218 is fixedly connected to the two support frames 5 217 and cannot move, the sliding block 215 and the guide rail frame 218 are fixedly connected to the two support frames 5 217. 8 The sliding connection is limited so that the sliding block 215 can only perform horizontal reciprocating motion on the outside of the screw rod 216. One side of the reciprocating sliding block 215 is fixedly connected to a support frame 4 214. The support frame 3 212 fixedly connected to the support frame 4 214 is fixedly connected to the cleaning piece 213. The pull rope 22 passes through the support frame 3 212 and the cleaning piece 213. Therefore, when the sliding block 215 drives the support frame 3 212 and the cleaning piece 213 to move outside through the support frame 4 214, a reciprocating force is applied to the pull rope 22 near the winding position of the winding frame 211, so that the pull rope 22 is evenly arranged and wound around the outside of the winding frame 211, reducing the possibility of the pull rope 22 being tangled.

[0047] In addition, other, such as Figure 7 and Figure 8 and Fig.12As shown, in the connection structure 4, a splicing tube 3 43 is arranged inside the splicing tube 1 41 and the splicing tube 2 42, and the splicing tube 1 41 and the splicing tube 2 42 are fixedly connected to the adjacent connecting tube 4 310 at one end away from each other, and the two splicing tubes 1 41 are fitted together to connect the two adjacent connecting tubes 4 310 together; and a spring-type telescopic rod 47 is arranged on the side away from each other of the two splicing tubes 3 43, and a plurality of fixing frames 2 49 are fixedly connected to the outer wall of the spring-type telescopic rod 47, and a sealing circular plate 46 is fixedly connected between the plurality of fixing frames 2 49, so that The outer wall of the spring-type telescopic rod 47 is fixedly connected to the connecting pipe 4310 through a plurality of fixing frames 1 48, so the relative position between the sealing circular plate 46 and the outer wall of the spring-type telescopic rod 47 remains unchanged; one end of the plurality of fixing frames 411 is fixedly connected to the adjacent splicing pipe 3 43, and the fixing frame 3 410 fixedly connected between the plurality of fixing frames 411 is fixedly connected to the piston end of the adjacent spring-type telescopic rod 47. When the spring-type telescopic rod 47 can be extended and retracted, the relative position between the splicing pipe 3 43 and the splicing pipe 1 41 can be changed;

[0048] When no airflow is infused into the arc-shaped air guide duct structure, the piston end portions of the multiple spring-type telescopic rods 47 are extended to the initial position, and the two splicing tubes 3 43 are in the initial position. At this time, the two splicing tubes 3 43 are respectively located on the outsides of the two sealing circular plates 46 to form a sealing structure, so that the two connecting tubes 4 310 are in a sealed state, and there is no obstruction between the splicing tube 1 41 and the splicing tube 2 42. Therefore, at this time, the multiple electromagnets 25 are controlled to stop working, so that the pressure relief valve 312 fixedly connected to the connecting tube 4 310 loses its fixation, and the connecting tube 4 310 loses its fixation. A tool can be used to hook the hook 313 fixedly connected to the top of the connecting tube 4 310, and the connecting tube 4 310 can be pulled up to inspect and maintain the multiple pressure relief valves 312 and the bubble generator 311 fixedly connected to the connecting tube 4 310. The multiple connecting tubes 4 310 can be inspected and repaired in sections, and the inspection requires less space and the one-time workload is less, thereby avoiding the situation where local damage requires the replacement of the entire arc-shaped air guide duct structure.

[0049] When gas is infused into the arc-shaped gas-guiding duct structure, the airflow enters the interior of the arc-shaped gas-guiding duct structure from the connecting tube four 310 near the connecting tube three 39, and acts on the multiple connecting structures 4 in turn. After the airflow enters the interior of the connecting tube four 310, it will push the splicing tube three 43 set on one side of the interior of the connecting tube four 310 to move. The inner wall of the splicing tube three 43 is set in a stepped shape, and the inner diameter of a small part of the splicing tube three 43 is the same as the outer diameter of the sealing circular plate 46, so that the splicing tube three 43 and the sealing circular plate 46 cooperate to seal one end of the connecting tube four 310, while the inner diameter of most of the splicing tube three 43 is larger than the outer diameter of the sealing circular plate 46. After the splicing tube three 43 moves a small distance, the sealing state between the splicing tube three 43 and the sealing circular plate 46 can be removed, and the moving splicing tube three 43 pushes the adjacent splicing tube three 43 to move, so that it also leaves the outside of the internal sealing circular plate 46, and at this time, the two connecting tubes four 310 are connected; with the flow of airflow, the working states of the multiple connecting structures 4 change, and the multiple connecting tubes four 310 are connected.

[0050] And no matter whether the left or right air pump 38 is working, the working state of the connecting structure 4 will change, so that the multiple connecting pipes 4 310 are connected; and after the working state of the connecting structure 4 changes, a splicing pipe 3 43 will be transported to the interface of the splicing pipe 1 41 and the splicing pipe 2 42 and come out of the bottom, and the outer diameter of the splicing pipe 3 43 is the same as the inner diameter of the splicing pipe 1 41 and the splicing pipe 2 42, so after the working state of the connecting structure 4 changes, the splicing pipe 3 43 plays a role in sealing the splicing pipe 1 41 and the splicing pipe 2 42, ensuring the sealing of the airflow flowing inside the arc-shaped air guide duct structure and the quality of bubble generation.

[0051] A plurality of annular grooves 44 are provided on one side of a splicing tube 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 tube three 43 away from the spring-type telescopic rod 47. After the splicing tube three 43 moves, the plug-in plates 45 will enter the annular grooves 44, so that the two splicing tubes three 43 are snapped together. One of the splicing tubes three 43 is arranged inside the contact position between the splicing tube one 41 and the splicing tube two 42 to support the splicing tube one 41 and the splicing tube two 42, thereby further increasing the stability between the two connecting tubes four 310.

[0052] In addition, such as Figure 2 and Figure 4As shown, a bevel gear 1 314 is rotatably connected to the top of the outer side of the insulation tower 31, and the bevel gear 1 314 is meshed with a bevel gear 2 316. The handwheel 315 fixedly connected inside the bevel gear 2 316 is operated to rotate, so that the handwheel 315 rotates on one side of the insulation tower 31, and the handwheel 315 drives the bevel gear 2 316 to rotate, and the rotating bevel gear 2 316 drives the bevel gear 1 314 to rotate, and the bevel gear 1 314 is fixedly connected to the support frame 6 318, so the bevel gear 1 314 drives the support frame 6 318 to rotate, and the support frame 6 318 rotatably connected to the top of the insulation tower 31 rotates, and the bolt 319 threadedly connected to the support frame 6 318 is fixedly connected to the liquid level sensor 7, so that the liquid level sensor 7 rotates to the top of the hyperbolic arch dam body 1, and the liquid level sensor 7 installed by the threaded structure can be quickly disassembled, and the liquid level sensor 7 can be conveniently and quickly inspected and repaired.

[0053] A limit vertical plate 317 is fixedly connected to the top of the insulation tower 31, and the limit vertical plate 317 blocks the position of the support frame six 318. After the support frame six 318 is controlled to rotate clockwise to drive the liquid level sensor 7 to rotate above the water surface, the movement of the support frame six 318 is limited by the limit vertical plate 317.

[0054] In addition, such as Fig.11 As shown, a support frame 26 is fixedly connected to the side of the support frame 1 23 away from the hyperbolic arch dam body 1, and a metal mesh 27 is fixedly connected to one end of the support frame 26. When the clockwise rotation movement of the support frame 6 318 is blocked by the limiting vertical plate 317, the liquid level sensor 7 stays on the top of the metal mesh 27, and the metal mesh 27 blocks garbage and impurities on the outside, so the water level inside the metal mesh 27 is not affected by floating objects, ensuring that the liquid level sensor 7 accurately detects the water level height.

[0055] In addition, such as Fig. 9 As shown, a long groove 221 is opened at the bottom of the device housing 21, and the top end of the pull rope 22 passes through the long groove 221 and enters the interior of the device housing 21. The long groove 221 provides space for the local reciprocating motion of the pull rope 22.
