Description

Technical Field

[0001] The invention relates to the technical field of water conservancy project construction, and in particular to an automatic repair method for cracks in a spillway. Background Art

[0002] Spillways are structures used in water conservancy projects to safely discharge excess water from reservoirs, lakes and other water storage facilities, and are equivalent to the "safety valve" of reservoirs. Their core function is to prevent dam breaches caused by excessive water levels and to ensure the safety of the dam and downstream areas.

[0003] For example, the Oroville Dam spillway accident in the United States occurred in 2017. There were cracks and joints in the bottom plate of the spillway chute. High-speed water flow passed through the cracks and washed away the bedrock below the bottom plate, causing the bottom plate to be overturned and forming a cavity. The staff ignored the crack problem for a long time and failed to repair the aging structure in time. The chute bottom plate was damaged over a large area, and the non-use spillway was forced to be used, resulting in erosion of the downstream mountains. 188,000 people were evacuated urgently and the repair cost was as high as 1 billion US dollars, making it one of the most expensive accidents in the history of American water conservancy.

[0004] At present, the cracks in the spillway are mostly repaired by manually chiseling the cracks and then pouring cement slurry into the cracks. This method is time-consuming, labor-intensive, inefficient, and not conducive to dam repair, especially the repair of dams with many cracks. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a time-saving and labor-saving spillway crack automatic repair method, which can specifically adopt the following technical solutions: The automatic crack repair method of the spillway of the present invention is realized by an automatic crack repair device of the spillway, and the automatic crack repair device of the spillway comprises a mobile cart, and an upper extension plate and a lower extension plate are arranged at the front end of the mobile cart, and two groups of upper extension plates and lower extension plates are arranged correspondingly in the upper and lower parts, and a vertically lifting movable plate is arranged between the upper extension plates and the lower extension plates of the same group, and a crack repair mechanism is arranged on the movable plate, and a water supply mechanism, a slurry supply mechanism and a hot air blower are also arranged on the mobile cart; The crack repair mechanism includes a drill bit, a conveying pipeline, a transfer bin, a water delivery telescopic hose, a slurry delivery telescopic hose and an air supply telescopic hose.

When in use, it saves time and effort, and can greatly improve the repair quality and repair efficiency of the cracks in the spillway.

[0016] Compared with the prior art, the specific advantages of the present invention are as follows: 1. The automatic repair device adopted by the present invention is provided with a crack repair mechanism, a water supply mechanism, a slurry supply mechanism and a hot air blower. The drill bit is used to drill into the crack, and then water, hot air and cement slurry are sprayed out in sequence through the through hole. The crack can be flushed inside by the high-pressure water flow to wash the inside of the crack, and the corrupt layer inside the crack can be made to fall off. By blowing hot air into the crack, the inside of the crack can be dried.

Through the meshing of the first bevel gear and the second bevel gear, the second stirring paddle can be driven to rotate, so as to remix the cement slurry entering the transfer bin, further ensuring the fluidity and mixing uniformity of the cement slurry. For the cement slurry with uniform mixing, the internal components are more evenly distributed, which can better exert the bonding effect of the cement, thereby improving the overall compressive strength and tensile strength. Moreover, the uniform cement slurry can better control the hydration heat and reduce the temperature stress, thus reducing the possibility of crack generation.

[0019] 4. The automated repair device adopted in the present invention is provided with a leveling mechanism. After the crack filling repair is completed, the movable plate will drive the crack repair mechanism to move upward. At this time, the pulling rope will release the limit on the cross beam plate, and the cross beam plate will slide downward along the second limiting rod under the action of gravity. Finally, the second servo motor drives the scraper to rotate, which can level the surface of the crack repair, thereby reducing the impact force and adhesion force of the water flow at this place during the flood discharge of the spillway, effectively avoiding the recurrence of cracks, and then extending the service life of the spillway.

Detailed implementation mode

[0028] The following detailed description of the embodiments of the present invention is given on the premise of the technical solution of the present invention, and the detailed implementation mode and specific working process are provided, but the protection scope of the present invention is not limited to the following embodiments.

[0029] Such as Figure 1-7As shown in the figure, the automatic repair method for the spillway crack of the present invention is realized by an automatic repair device for the spillway crack, which includes a mobile trolley 1. An upper extension plate 2 and a lower extension plate 3 are arranged at the left end of the mobile trolley 1. There are two groups of upper extension plates 2 and lower extension plates 3 arranged corresponding to each other up and down. An activity plate 4 capable of vertical lifting is arranged between the upper extension plate 2 and the lower extension plate 3 of the same group. A crack repair mechanism is arranged on the surface of the activity plate 4. A water supply mechanism 5, a slurry supply mechanism 6 and a hot air blower 7 are respectively arranged on the surface of the mobile trolley 1. Among them, the crack repair mechanism includes a drill bit 8, a conveying pipeline 9, a transfer bin 10, a water conveyance telescopic hose 11, a slurry conveyance telescopic hose 12 and a hot air conveyance telescopic hose 13. The conveying pipeline 9 is rotatably connected to the middle of the activity plate 4. Through holes 14 are respectively arranged on both sides of the lower end of the conveying pipeline 9. The drill bit 8 is fixedly connected to the lower end of the conveying pipeline 9. The transfer bin 10 is rotatably installed at the upper end of the conveying pipeline 9, and the lower end of the transfer bin 10 is communicated with the conveying pipeline 9. The water conveyance telescopic hose 11, the slurry conveyance telescopic hose 12 and the hot air conveyance telescopic hose 13 are all communicated with the upper end of the transfer bin 10. The upper end of the water conveyance telescopic hose 11 is communicated with the output end of the water supply mechanism 5. The upper end of the slurry conveyance telescopic hose 12 is communicated with the output end of the slurry supply mechanism 6. The upper end of the hot air conveyance telescopic hose 13 is communicated with the output end of the hot air blower 7. By arranging the crack repair mechanism, the water supply mechanism 5, the slurry supply mechanism 6 and the hot air blower 7, the drill bit 8 is used to drill into the crack, and then water, hot air and cement slurry are sprayed out in sequence through the through hole 14. The crack can be washed internally by high-pressure water flow, which can make the corrupt layer inside the crack fall off. This step can remove the dust, loose particles and other impurities in the crack, ensuring that the repair material can be in close contact with the crack wall and improving the repair effect. By blowing hot air into the crack, the crack can be air-dried. It should be noted that repairing after air-drying the crack can help the cement slurry to cure quickly in a dry state, shortening the repair time. At the same time, it avoids the residual water in the crack diluting the cement slurry, resulting in the curing and hardening of the cement slurry being affected, and ultimately affecting the crack repair quality. Moreover, the moisture on the surface of the crack will affect the adhesion of the repair material. Air-drying can ensure that the surface of the crack is dry, thereby improving the bonding force between the repair material and the crack wall and enhancing the repair effect. Finally, the cement slurry is sprayed out through the through hole 14 to fill and repair the crack, thus realizing the automatic repair of the spillway crack. The repair process is time-saving and labor-saving, effectively improving the repair efficiency and repair quality.

[0030] An adjusting screw 15 and a first limiting rod 16 are also provided between the upper extension plate 2 and the lower extension plate 3. The adjusting screw 15 is rotatably connected between one group of the upper extension plate 2 and the lower extension plate 3, and the first limiting rod 16 is fixedly connected between the other group of the upper extension plate 2 and the lower extension plate 3. A first servo motor 17 is fixedly connected to the upper surface of the upper extension plate 2 on which the adjusting screw 15 is installed, and the adjusting screw 15 is transmission-connected to the output end of the first servo motor 17. One end of the movable plate 4 is threadedly connected to the adjusting screw 15, and the other end of the movable plate 4 is slidably connected to the first limiting rod 16. By providing the adjusting screw 15, the first limiting rod 16 and the first servo motor 17, the adjusting screw 15 is driven to rotate by the first servo motor 17, and the movable plate 4 is limited by the first limiting rod 16, so that the height of the movable plate 4 can be adjusted so that the movable plate 4 can be lifted up and down.

[0031] The surface of the movable plate 4 is provided with a power mechanism for driving the conveying pipe 9 to rotate, and the power mechanism includes a power motor 18, a first gear 19 and a second gear 20. The power motor 18 is fixedly connected to the surface of the movable plate 4, the first gear 19 is fixedly connected to the outer surface of the output end of the power motor 18, the second gear 20 is fixedly connected to the outer surface of the conveying pipe 9, and the first gear 19 and the second gear 20 are meshed with each other. By setting up the power mechanism, the power motor 18 is used to drive the first gear 19 to rotate, and the first gear 19 and the second gear 20 are meshed with each other, so that the conveying pipe 9 can be driven to rotate, thereby driving the drill bit 8 to rotate. The rotation of the drill bit 8 can be used to break the crack and extend the conveying pipe 9 into the crack.

[0032] Two limit plates 21 are fixedly connected to the outer surface of the conveying pipe 9, and the opposite surfaces of the two limit plates 21 are embedded with multiple balls 22 that interfere with the movable plate 4. By setting two limit plates 21 and multiple balls 22, the conveying pipe 9 can be limited by the two limit plates 21, and the friction between the limit plates 21 and the movable plate 4 can be reduced by rolling the multiple balls 22, thereby facilitating the rotation of the conveying pipe 9.

[0033] The water supply mechanism 5 includes a water pump 23, a water suction pipe 24 and a water tank 25. The water pump 23 and the water tank 25 are both fixedly mounted on the mobile cart 1. The water suction pipe 24 is arranged between the input end of the water pump 23 and the water tank 25. By setting up the water supply mechanism 5 and utilizing the water pump 23 to work, the water in the water tank 25 can be transported into the water delivery telescopic hose 11 through the water suction pipe 24.

[0034] The slurry supply mechanism 6 includes a slurry pump 26, a slurry pipe 27, and a slurry tank 28. Both the slurry pump 26 and the slurry tank 28 are fixedly installed on the mobile trolley 1. The slurry pipe 27 is arranged between the input end of the slurry pump 26 and the slurry tank 28. By setting the slurry supply mechanism 6 and using the slurry pump 26 to work, the cement slurry in the slurry tank 28 can be transported through the slurry pipe 27 and into the slurry delivery telescopic hose 12.

[0035] In practical applications, the water supply mechanism 5 can also be used to flush the transfer bin 10 and the conveying pipeline 9, thus preventing the conveying pipeline 9 and the transfer bin 10 from being blocked by slurry.

[0036] A first stirring paddle 29 is arranged inside the slurry tank 28, and the first stirring paddle 29 is drivingly connected to the moving wheel 31 of the mobile trolley 1 through a pulley drive assembly 30. By setting the first stirring paddle 29 and the pulley drive assembly 30, when the mobile trolley is moving, the rotation of the moving wheel 31 can drive the first stirring paddle 29 to rotate, thereby stirring the cement slurry in the slurry tank 28, ensuring the fluidity and uniformity of the cement slurry, and thus contributing to the subsequent crack repair work.

[0037] In practical applications, a servo motor and a drive assembly can also be used to drive the moving wheel 31 to rotate, thus facilitating the movement of the entire mobile trolley 1.

[0038] A second stirring paddle 32 is rotatably connected inside the transfer bin 10. The upper end of the output end of the power motor 18 is fixedly connected with a first bevel gear 33, and the end of the second stirring paddle 32 is fixedly connected with a second bevel gear 34. The first bevel gear 33 and the second bevel gear 34 are meshed with each other. By setting the second stirring paddle 32, the first bevel gear 33, and the second bevel gear 34, while the power motor 18 drives the conveying pipeline 9 and the drill bit 8 to rotate, the first bevel gear 33 can also be driven to rotate. Through the meshing of the first bevel gear 33 and the second bevel gear 34, the second stirring paddle 32 can be driven to rotate, thereby stirring the cement slurry entering the transfer bin 10 again, further ensuring the fluidity and mixing uniformity of the cement slurry. The evenly mixed cement slurry has a more uniform internal component distribution, can better exert the bonding effect of the cement, thereby improving the overall compressive strength and tensile strength, and the uniform cement slurry can better control the hydration heat, reduce the temperature stress, and thus reduce the possibility of crack generation.

[0039] Further, two second limiting rods 35 are fixedly connected between the upper extension plate 2 and the lower extension plate 3, and a cross beam plate 36 is slidably connected to the outer surfaces of the two second limiting rods 35. A guide post 37 is rotatably connected between the two upper extension plates 2. A pull rope 38 bypassing the guide post 37 is fixedly connected between the cross beam plate 36 and the movable plate 4. A smoothing mechanism is fixedly connected to the surface of the cross beam plate 36. The smoothing mechanism includes a second servo motor 39 and a scraper 40. The second servo motor 39 is fixedly connected to the upper surface of the cross beam plate 36, and the scraper 40 is fixedly connected to the output end of the second servo motor 39. By providing the smoothing mechanism, after the crack grouting repair is completed, the movable plate 4 will drive the crack repair mechanism to move upward. At this time, the pull rope 38 will release the limit on the cross beam plate 36, and the cross beam plate 36 will slide downward along the second limiting rod 35 under the action of gravity. When the scraper 40 contacts the surface of the spillway, finally, the second servo motor 39 is used to drive the scraper 40 to rotate, so that the surface of the crack repair can be smoothed, thereby reducing the impact force and adhesion force of the water flow at this place when the spillway discharges flood, effectively avoiding the recurrence of cracks, and then extending the service life of the spillway.

[0040] The automated repair method for cracks in the spillway of the present invention includes the following steps: S1, slowly lower the movable plate 4 and cooperate with the rotation of the conveying pipeline 9 to make the drill bit 8 drill into the crack of the spillway; S2, inject water into the water conveying telescopic hose 11 through the water supply mechanism 5, so that the water passes through the transfer bin 10, the conveying pipeline 9, and finally sprays out from the through hole 14, thereby flushing the inside of the crack; S3, input hot air into the air supply telescopic hose 13 through the hot air blower 7, so that the hot air passes through the transfer bin 10, the conveying pipeline 9, and finally sprays out from the through hole 14, thereby drying the inside of the crack; S4, inject cement slurry into the slurry conveying telescopic hose 12 through the slurry supply mechanism 6, so that the cement slurry passes through the transfer bin 10, the conveying pipeline 9, and finally sprays out from the through hole 14, thereby filling the cement slurry into the crack; if necessary, perform a surface smoothing operation through the scraper 40 of the smoothing mechanism; S5, after the crack grouting is completed, use the movable plate 4 to move upward to withdraw the conveying pipeline 9 and the drill bit 8 from the inside of the crack.

[0041] It should be noted that in the description of the present invention, terms indicating orientation or positional relationships such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
