Description

Technical Field

[0001] This invention relates to the field of bridge pier spray curing technology, specifically to an automatic circulating spray curing device for bridge piers. Background Technology

[0002] Currently, after bridge piers are cast, they all require a certain period of moisturizing and curing to improve their early strength. In order to solve the problems of large workload, discontinuous curing and poor effect caused by traditional manual watering, the existing technology uses automatic sprinkler curing equipment for bridge piers. However, the water droplets sprayed on the outside of the bridge pier slide downwards, causing the outside of the bridge pier to dry quickly, resulting in too high a spraying frequency. If geotextile and plastic film are wrapped around the outside of the bridge pier one after the other, it will affect the uniformity of water spraying and affect the effect of sprinkler curing. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome the shortcomings of existing systems and provide an automatic circulating spray curing device for bridge piers. Before spraying, a cover lifting assembly moves each movable plastic film sleeve downwards to overlap with the fixed plastic film sleeve, exposing the gauze covering the water spray gaps. A spraying distribution mechanism drives the spray heads in the spray curing mechanism to swing left and right, spraying water onto the gauze covering the water spray gaps, improving the uniformity of spraying the bridge piers. Then, due to the water absorption characteristics of the gauze covering, the gauze covering the inside of the fixed plastic film sleeve also becomes damp. The cover lifting assembly then moves each movable plastic film sleeve upwards, sealing the water spray gaps and reducing the evaporation of water from the gauze covering. This reduces the spraying frequency, saves water, and provides a good spray curing effect for bridge piers, effectively solving the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic circulating spray curing device for bridge piers, comprising: The membrane-covering and moisturizing mechanism includes a fixed base frame, a sliding bracket, a covering and lifting assembly, a covering gauze, a fixed plastic film sleeve, and a movable plastic film sleeve. The covering gauze wraps around the outside of the bridge pier. Fixed plastic film sleeves are vertically and equidistantly fitted onto the outside of the covering gauze, with a water spraying gap between adjacent fixed plastic film sleeves. The fixed base frame surrounds the bottom of the bridge pier. The top of the fixed base frame is connected to the top of the covering and lifting assembly via the sliding bracket. Film sleeve support frames are vertically and equidistantly arranged on the inner side of the bottom of the covering and lifting assembly. Movable plastic film sleeves are arranged on the inner side of each film sleeve support frame, and the movable plastic film sleeves are located outside the fixed plastic film sleeves. A spraying displacement mechanism is installed on a fixed base frame and is arranged around the bridge pier. A spraying distribution mechanism is installed on the spraying displacement mechanism, and a spraying curing mechanism is installed on the spraying distribution mechanism. The circulating water supply mechanism is installed on the bottom side of the bridge pier and is connected to the spray curing mechanism.

[0005] The fixed base frame is used to install the fixed sliding bracket, which in turn is used to install the cover lifting assembly and guides the up-and-down movement of the spraying displacement mechanism. The cover lifting assembly moves the film sleeve support frame and the movable plastic film sleeve up and down. When the cover lifting assembly moves the film sleeve support frame and the movable plastic film sleeve downwards, the movable plastic film sleeve overlaps with the fixed plastic film sleeve. At this point, the position of the covering gauze corresponding to the water spraying gap is exposed. When the spraying displacement mechanism moves the spraying distribution mechanism to the position corresponding to the water spraying gap, the spraying maintenance mechanism sprays water onto the covering gauze at the water spraying gap. The absorbent cloth also moistens the gauze wrapped in the plastic film. By wrapping the bridge pier with the damp gauze, the outer side of the bridge pier remains moist, which is beneficial for the curing effect of the bridge pier. Then, the cover lifting component moves the film cover support frame and the movable plastic film cover upward, so that the movable plastic film cover blocks the water spray gaps, preventing the moisture in the gauze from evaporating through the water spray gaps. This can save water and reduce the frequency of spray curing. The circulating water supply mechanism can collect the excess water flowing out from the bottom of the gauze, and additional water can be added to the circulating water supply mechanism to supply water to the spray curing mechanism.

[0006] Furthermore, the sliding bracket includes round bases, columns, screws, and a top frame. Four round bases are bolted to the four upper corners of the fixed base frame. The tops of the four round bases are fixed to the bottom ends of the four columns. The tops of the four columns are bolted to the four corners of the top frame. The top of the top frame is connected to the top of the cover lifting assembly in the middle. The bolts and round bases allow for the detachable installation of the columns, facilitating installation during use and disassembly for easy transport when not in use. Screws are used for the detachable installation of the top frame, which is used to install the cover lifting assembly.

[0007] Furthermore, the spraying displacement mechanism includes sliding sleeves, a displacement frame, and a lifting and displacement assembly. Four sliding sleeves are fixedly connected to the four corners of the displacement frame, and each sliding sleeve is vertically slidably connected to a corresponding column. The bottom of the lifting and displacement assembly is installed on one side of the fixed base frame, and the lifting and displacement assembly is connected to the side of the displacement frame. The lifting and displacement assembly is used to drive the displacement frame to move up and down, thereby driving the spraying distribution mechanism to move up and down, allowing the spraying distribution mechanism to evenly spray the gauze covering the water gaps. The sliding sleeves cooperate with the columns to guide the up and down movement of the displacement frame.

[0008] Furthermore, the spraying distribution mechanism includes a through groove, a swing shaft, a swing rod, a support rod, a mounting sleeve, fastening bolts, a synchronization component, and a uniformly distributed swing component. Each side of the shifting frame has through grooves at equal intervals. The middle of the swing rod is movably connected to each through groove via a swing shaft. The top of the swing rod located inside the shifting frame is fixedly connected to the bottom of the support rod. A mounting sleeve is fixedly connected to the top of the support rod, and a fastening bolt is threaded into the threaded hole on the side of the mounting sleeve. The ends of the swing rods on the same side of the shifting frame located inside the shifting frame are connected via a synchronization component. The ends of the swing rods located in the middle of each side of the shifting frame located outside the shifting frame are respectively connected to the uniformly distributed swing component. The uniformly distributed swing component is used to drive the swing arm in the middle of the side of the displacement frame to swing left and right around the swing axis. The synchronization component allows each swing arm on the same side of the displacement frame to swing left and right synchronously, thereby driving the mounting sleeve at the top of the support rod to swing left and right. The fastening bolt is used for detachable installation inside the mounting sleeve. The mounting sleeve drives the spray head in the spray curing mechanism to swing left and right to achieve uniform spraying.

[0009] Furthermore, the synchronization component includes a movable column and a synchronization rod. The ends of each swing rod on the same side of the shifting frame, located inside the shifting frame, are movably connected to the synchronization rod via the movable column. The synchronization rod connects to each swing rod on the same side of the shifting frame via the movable column. When the evenly distributed swing component drives one swing rod on the same side of the shifting frame to swing, all swing rods on the same side of the shifting frame swing synchronously.

[0010] Furthermore, the uniformly distributed swing assembly includes a motor bracket, three screws, a swing motor, a crank, a movable shaft, a fan-shaped slider, and an arc-shaped slide rail. The swing arm at the center of each side of the shifting frame is fixedly connected to the inner center of the arc-shaped slide rail at one end of the outer side of the shifting frame. The motor bracket is fixedly connected to the outer side of the center of each side of the shifting frame via three screws. The swing motor is fixedly mounted in the center of the motor bracket. One end of the crank is fixedly connected to the output shaft of the swing motor. The other end of the crank is movably connected to the fan-shaped slider via the movable shaft. The fan-shaped slider is slidably connected to the arc-shaped groove on the outer side of the arc-shaped slide rail. Three screws enable the detachable installation of the motor bracket, which is used to mount the swing motor. The swing motor drives the crank to rotate, which in turn drives the movable shaft and the fan-shaped slider to rotate around the output shaft of the swing motor. The sliding of the fan-shaped slider against the arc-shaped slide rail counteracts the vertical displacement of the fan-shaped slider. The horizontal movement of the fan-shaped slider causes the arc-shaped slide rail to move horizontally, thereby causing the swing arm to swing horizontally around the swing shaft.

[0011] Furthermore, the spraying maintenance mechanism includes spray heads, hoses, manifolds, pipe supports, delivery pipes, and a spray water pump. Each mounting sleeve houses a spray head, with fastening bolts securing the corresponding spray head. The inlet of each spray head is connected to one end of the hose. The other ends of the hoses on the same side of the shifting frame are connected to the manifold. The manifold is fixed to the shifting frame by the pipe supports. The end of each manifold is connected to the outlet of the spray water pump via a delivery pipe. The spray water pump is mounted on a fixed base frame. The pipe supports are used to install the manifolds. The spray water pump pumps water into the manifolds through the delivery pipes. The water in the manifolds is delivered to the spray heads through the hoses and then sprayed out through the spray heads. The delivery pipes are flexible, and their length must ensure that they do not interfere with the vertical movement of the shifting frame. The use of hoses allows the spray heads to swing left and right.

[0012] Furthermore, the circulating water supply mechanism includes a recycling tank, a recycling power unit, and a water tank. The recycling tank is located on the bottom side of the bridge pier. The recycling tank is connected to the water tank via the recycling power unit, and the water tank is connected to the inlet of each spray pump via an external pipe. If too much water is sprayed, excess water will gradually drip down from the gauze covering the outside of the bridge pier. The dripping water collects in the recycling tank and is then transported to the water tank for recycling via the recycling power unit. The water tank can be pre-filled with the water needed for spraying.

[0013] Furthermore, the system also includes a spray position control mechanism, which comprises a rectangular mounting frame, limit switches, and a triggering component. The rectangular mounting frame is fixedly connected to the outer side of the shifting frame. A limit switch is installed inside the rectangular mounting frame near the shifting frame, and a triggering component is installed on the side of the rectangular mounting frame away from the shifting frame. The rectangular mounting frame is used to mount the limit switch and connect the triggering component. The triggering component activates the limit switch as the shifting frame moves up and down. The output terminal of the limit switch is electrically connected to the input terminal of each spray pump.

[0014] Furthermore, the triggering component includes a vertical rod, a protruding strip, a roller, a wheel frame, a sliding square rod, a pressing block, and a return spring. A sliding square rod is slidably connected to a square hole on the side of the rectangular mounting frame away from the displacement frame. A pressing block is fixedly connected to one end of the sliding square rod inside the rectangular mounting frame. A wheel frame is fixedly connected to the other end of the sliding square rod. A roller is rotatably connected to the wheel frame via a wheel axle. A return spring is sleeved on the portion of the sliding square rod between the wheel frame and the rectangular mounting frame. The bottom end of the vertical rod is fixedly connected to the outside of the fixed base frame. A protruding strip is fixedly connected to the side of the vertical rod near the displacement frame at a position corresponding to the water spraying gap. The upper and lower ends of the protruding strip are respectively provided with inclined surfaces. The roller makes rolling contact with the side of the vertical rod near the displacement frame. When the shifting frame moves up and down, it drives the rectangular mounting frame to move up and down as well. At this time, the roller rolls along the side of the vertical rod closest to the shifting frame. When the shifting frame aligns with the water spray gap, the roller also aligns with the convex strip. The convex strip pushes the roller, wheel frame, and sliding rod along the square hole towards the limit switch. The pressing block at the end of the sliding rod triggers the limit switch, which controls the spray pump to work, spraying water onto the gauze covering the water spray gap through the spray head. At this time, the return spring is compressed. When the shifting frame no longer aligns with the water spray gap, the roller also synchronously moves away from the convex strip and continues... When the contact bar is reached, the return spring extends and resets, causing the pressing block at the end of the sliding square bar to move away from the limit switch. The limit switch is no longer triggered, and the sprinkler pump stops working, ensuring that water is sprayed only onto the gauze covering the water spray gaps, and not onto the outside of the fixed and movable plastic film sleeves. Therefore, the fixed and movable plastic film sleeves are waterproof and will not absorb water and moisten the bridge piers like the gauze covering. After spraying, the fixed and movable plastic film sleeves surround the gauze covering, reducing the evaporation of water from the gauze covering.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This automatic circulating spray curing device for bridge piers has the following advantages: 1. Before spraying, the cover lifting assembly moves each movable plastic film sleeve down to overlap with the fixed plastic film sleeve, exposing the gauze covering the water spray gap. The spraying uniform distribution mechanism can drive the spray head in the spray curing mechanism to swing left and right. The spray head sprays water onto the gauze covering the water spray gap, which can improve the uniformity of spraying the bridge pier. Then, due to the water absorption characteristics of the gauze covering, the gauze covering the inside of the fixed plastic film sleeve is also wet. Then, the cover lifting assembly moves each movable plastic film sleeve up to close the water spray gap, reducing the evaporation of water on the gauze covering, which can reduce the spraying frequency, save water, and have a good spray curing effect on the bridge pier. 2. The circulating water supply system can collect excess water flowing out from the bottom of the gauze covering. At the same time, additional water can be added to the circulating water supply system to supply water to the spray health care system, which can save water. 3. By reducing water evaporation and recycling excess water, water resources can be greatly saved, making it suitable for spray curing of bridge piers in arid regions. Attached Figure Description

The covering gauze 212 is wrapped around the outside of the bridge pier 1. The fixed plastic film sleeve 213 is vertically and equidistantly sleeved on the outside of the covering gauze 212. A water spraying gap is left between two adjacent fixed plastic film sleeves 213. The fixed base frame 21 surrounds the bottom of the bridge pier 1. Anchor holes are opened at equal intervals on the fixed base frame 21. Anchor rods are inserted into the anchor holes to fix the fixed base frame 21. The top of the fixed base frame 21 is connected to the top of the covering and lifting assembly through the sliding bracket. The film sleeve support frame is vertically and equidistantly arranged on the inner side of the bottom of the covering and lifting assembly. A movable plastic film sleeve 216 is arranged on the inner side of each film sleeve support frame. The movable plastic film sleeve 216 is located on the outside of the fixed plastic film sleeve 213. The sliding bracket includes round bases 22, columns 23, screws 24, and a top frame 25. Four round bases 22 are bolted to the upper four corners of the fixed base frame 21. The tops of the four round bases 22 are fixed to the bottom ends of the four columns 23. The tops of the four columns 23 are fixed to the four corners of the top frame 25 via screws 24.

Screws 24 are used for the detachable installation of the top frame 25, which is used to install the cover lifting assembly.

[0019] The cover lifting assembly includes a lifting motor 26, a stud 27, a lifting frame 28, a screw 29, guide columns 210, and connecting columns 211. A crossbeam is located in the middle of the top frame 25, and the lifting motor 26 is installed in the middle of the crossbeam. The bottom output shaft of the lifting motor 26 is fixedly connected to the top of the stud 27. The stud 27 is threadedly connected to the screw hole in the middle of the lifting frame 28. Two vertical guide columns 210 are fixedly connected to the bottom of the crossbeam, and the two guide columns 210 are vertically slidably connected to the guide holes on the lifting frame 28. The lifting frame 28... The four corners are fixedly connected to the top of the four connecting columns 211 by four screws 29. When the lifting motor 26 works, it drives the screw 27 to rotate clockwise. The thread action between the screw 27 and the lifting frame 28 can drive the lifting frame 28 to move downward along the guide column 210. Thus, the connecting column 211 drives the film sleeve support frame and the movable plastic film sleeve 216 to move downward. When the lifting motor 26 works, it drives the screw 27 to rotate counterclockwise. Then the connecting column 211 drives the film sleeve support frame and the movable plastic film sleeve 216 to move upward. The film sleeve support frame includes a square frame 214, a connecting plate 215, and a short rod 217. There are two square frames 214, which are arranged vertically and vertically. The four corners of the two square frames 214 are connected by four connecting plates 215. The outer middle parts of the four connecting plates 215 are fixedly connected to four connecting posts 211 by the short rods 217. The two square frames 214 and the connecting plates 215 constitute the film sleeve support frame, which is used to support and install the movable plastic film sleeve 216, so as to facilitate the up and down movement of the movable plastic film sleeve 216.

[0020] The spraying displacement mechanism 3 is installed on the fixed base frame 21, and the spraying displacement mechanism 3 is arranged around the bridge pier 1. The spraying displacement mechanism 3 is equipped with a spraying uniform distribution mechanism 4, and the spraying uniform distribution mechanism 4 is equipped with a spraying curing mechanism 5.

[0021] The lifting and shifting assembly includes a convex plate 33, a disassembly seat 34, a linear motor guide rail 35, a support rod 36, and a shifting linear motor 37. The convex plate 33 is fixedly connected to one side of the fixed base frame 21. The disassembly seat 34 is fixedly connected to the convex plate 33 by convex plate bolts. The disassembly seat 34 is fixedly connected to the bottom end of the vertical linear motor guide rail 35. The shifting linear motor 37 is installed on the linear motor guide rail 35. The side of the shifting linear motor 37 is connected to the side of the shifting frame 32 by the support rod 36. The convex plate 33 enables the detachable installation of the linear motor guide rail 35 through the convex plate bolts and the disassembly seat 34. When the shifting linear motor 37 moves up and down along the linear motor guide rail 35, it can drive the shifting frame 32 to move up and down, realizing the lifting and lowering movement of the shifting frame 32.

[0022] The lifting and shifting component is used to drive the shifting frame 32 to move up and down, thereby driving the spraying distribution mechanism 4 to move up and down, so that the spraying distribution mechanism 4 can spray evenly onto the gauze 212 covering the water spraying gap. The sliding sleeve 31 and the column 23 cooperate to guide the up and down movement of the shifting frame 32.

[0023] The spraying distribution mechanism 4 includes a through groove 41, a swing shaft 42, a swing rod 43, a support rod 44, a mounting sleeve 45, a fastening bolt 46, a synchronization component, and a distribution swing component. Through grooves 41 are equally spaced on each side of the shifting frame 32. The middle part of the swing rod 43 is movably connected to each through groove 41 via the swing shaft 42. The top of the swing rod 43 located inside the shifting frame 32 is fixedly connected to the bottom end of the support rod 44. The top of the support rod 44 is fixedly connected to the mounting sleeve 45. The fastening bolt 46 is threaded into the threaded hole on the side of the mounting sleeve 45. The ends of the swing rods 43 on the same side of the shifting frame 32 located inside the shifting frame 32 are connected via the synchronization component. The ends of the swing rods 43 located in the middle of each side of the shifting frame 32 located outside the shifting frame 32 are respectively connected to the distribution swing component.

[0024] The uniformly distributed swing component is used to drive the swing rod 43 in the middle of the side of the displacement frame 32 to swing left and right around the swing axis 42. The synchronization component allows each swing rod 43 on the same side of the displacement frame 32 to swing left and right synchronously, thereby driving the mounting sleeve 45 at the top of the support rod 44 to swing left and right. The fastening bolt 46 is used for detachable installation inside the mounting sleeve 45. The mounting sleeve 45 drives the spray head 51 in the spray curing mechanism 5 to swing left and right to achieve uniform spraying.

[0025] The synchronization component includes a movable column 47 and a synchronization rod 48. The ends of each swing rod 43 on the same side of the shifting frame 32, located inside the shifting frame 32, are movably connected to the synchronization rod 48 via the movable column 47. The synchronization rod 48 connects to each swing rod 43 on the same side of the shifting frame 32 via the movable column 47. When the evenly distributed swing component drives one swing rod 43 on the same side of the shifting frame 32 to swing, all swing rods 43 on the same side of the shifting frame 32 swing synchronously.

[0026] The evenly distributed swing assembly includes a motor bracket 49, screw three 410, swing motor 411, crank 412, movable shaft 413, fan-shaped slider 414, and arc-shaped slide rail 415. The swing rod 43 in the middle of each side of the shifting frame 32 is fixedly connected to the inner middle of the arc-shaped slide rail 415 at one end located on the outer side of the shifting frame 32. The motor bracket 49 is fixedly connected to the outer side of the middle of each side of the shifting frame 32 by screw three 410. The swing motor 411 is fixed in the middle of the motor bracket 49. The output shaft of the swing motor 411 is fixedly connected to one end of the crank 412. The other end of the crank 412 is movably connected to the fan-shaped slider 414 through the movable shaft 413. The fan-shaped slider 414 is slidably connected to the arc-shaped groove on the outer side of the arc-shaped slide rail 415.

[0027] Screw 3 410 enables the detachable installation of motor bracket 49. Motor bracket 49 is used to install swing motor 411. Swing motor 411 drives crank 412 to rotate. Crank 412 drives movable shaft 413 and sector slider 414 to rotate around the output shaft of swing motor 411. The sliding of sector slider 414 and arc-shaped slide rail 415 can counteract the vertical displacement of sector slider 414. The left and right movement of sector slider 414 will drive arc-shaped slide rail 415 to move left and right, thereby driving swing arm 43 to swing left and right around swing shaft 42.

[0028] The circulating water supply mechanism 6 is installed on the bottom side of the bridge pier 1, and the circulating water supply mechanism 6 is connected to the spray curing mechanism 5.

[0029] In use, the fixed base frame 21 is used to install the fixed sliding bracket, which is used to install the cover lifting component and guide the up-and-down movement of the spraying shifting mechanism 3. The cover lifting component is used to drive the film sleeve support frame and the movable plastic film sleeve 216 to move up and down. When the cover lifting component drives the film sleeve support frame and the movable plastic film sleeve 216 to move downward, the movable plastic film sleeve 216 overlaps with the fixed plastic film sleeve 213. At this time, the position of the covering gauze 212 corresponding to the water spraying gap is exposed. When the spraying shifting mechanism 3 drives the spraying even distribution mechanism 4 to move to the position of the corresponding water spraying gap, the spraying maintenance mechanism 5 sprays water onto the covering gauze 212 at the water spraying gap. The water absorption of 212 causes the gauze 212 wrapped by the fixed plastic film sleeve 213 to become wet. By wrapping the bridge pier 1 with the wet gauze 212, the outer side of the bridge pier 1 is kept moist, which is good for the curing effect of the bridge pier 1. Then, the cover lifting component drives the film sleeve support frame and the movable plastic film sleeve 216 to move upward, so that the movable plastic film sleeve 216 blocks the water spraying gap, preventing the water in the gauze 212 from evaporating through the water spraying gap, which can save water and reduce the frequency of spray curing. The circulating water supply mechanism 6 can receive the excess water flowing out from the bottom of the gauze 212, and at the same time, additional water can be added to the circulating water supply mechanism 6 to supply water to the spray curing mechanism 5.

[0030] Example 2, please refer to Figures 1 to 9 This embodiment provides a technical solution: an automatic circulating spray curing device for bridge piers. This embodiment is a further explanation of the structure of Embodiment 1. The spraying maintenance mechanism 5 includes a spray head 51, a hose 52, a manifold 53, a pipe support, a delivery pipe 57, and a spray water pump 58. Each mounting sleeve 45 is fitted with a spray head 51, and the fastening bolts 46 abut against the corresponding spray head 51. The inlet of each spray head 51 is connected to one end of the hose 52. The other end of the hose 52 on the same side of the shifting frame 32 is connected to the manifold 53. The manifold 53 is fixed to the shifting frame 32 by the pipe support. The end of each manifold 53 is connected to the outlet of the spray water pump 58 through the delivery pipe 57. The spray water pump 58 is mounted on the fixed base frame 21.

[0031] The pipe support includes a base plate 54, a support rod 55, and a pipe sleeve 56. The two ends of the manifold 53 are respectively fitted with pipe sleeves 56. The bottom of each pipe sleeve 56 is fixedly connected to the base plate 54 by the support rod 55. The base plate 54 is fixed to the displacement frame 32 by base plate screws. The installation of the manifold 53 on the displacement frame 32 is completed by the cooperation of the base plate 54, the support rod 55, and the pipe sleeve 56.

[0032] The pipe support is used to install the manifold 53. The spray water pump 58 pumps water into the manifold 53 through the delivery pipe 57. The water in the manifold 53 is sent into the spray head 51 through the hose 52, and then sprayed out through the spray head 51. The delivery pipe 57 is a flexible pipe, and its length needs to ensure that it does not interfere with the up and down movement of the displacement frame 32. The use of the hose 52 allows the spray head 51 to swing left and right.

[0033] The circulating water supply mechanism 6 includes a recycling tank 61, a recycling power unit, and a water tank 65. The recycling tank 61 is located on the bottom side of the bridge pier 1. The recycling tank 61 is connected to the water tank 65 through the recycling power unit. The water tank 65 is connected to the inlet of each spray pump 58 through an external pipe. If there is too much water sprayed, excess water will gradually drip down from the gauze 212 covering the outside of the bridge pier 1. The dripping water collects in the recycling tank 61 and is then transported to the water tank 65 for recycling through the recycling power unit. The water tank 65 can be pre-filled with the water needed for spraying.

[0034] The circulating water supply mechanism 6 also includes a water inlet 66, a drain pipe 67, and a valve 68. The top of the water tank 65 is provided with a water inlet 66, through which clean water can be easily added to the water tank 65. Four drain pipes 67 are provided on the side of the water tank 65. The four drain pipes 67 are respectively connected to the inlet of four spray water pumps 58 through external pipes, and a valve 68 is installed on each drain pipe 67.

[0035] The recycling power assembly includes a return water pipe 62, a filter 63, and a recycling water pump 64. The bottom of the recycling tank 61 is connected to one end of the return water pipe 62, and the other end of the return water pipe 62 is connected to the inlet of the filter 63. The outlet of the filter 63 is connected to the inlet of the recycling water pump 64, and the outlet of the recycling water pump 64 is connected to the water tank 65. The water recycled in the recycling tank 61 enters the filter 63 through the return water pipe 62 for filtration. The filter 63 filters out the dirty water to prevent the spray head 51 from clogging after recycling. The filtered water is sent to the water tank 65 through the recycling water pump 64 for the next use.

[0036] Example 3, please refer to Figures 1 to 9 This embodiment provides a technical solution: an automatic circulating spray curing device for bridge piers. This embodiment is structurally similar to Embodiment 2, with the difference being: It also includes a spray position control mechanism 7, which comprises a rectangular mounting frame 75, a limit switch 76, and a trigger assembly. The rectangular mounting frame 75 is fixedly connected to the outside of the shifting frame 32. The limit switch 76 is installed inside the rectangular mounting frame 75 on the side closer to the shifting frame 32, and the trigger assembly is installed on the side of the rectangular mounting frame 75 away from the shifting frame 32. The rectangular mounting frame 75 is used to install the limit switch 76 and connect the trigger assembly. The trigger assembly triggers the limit switch 76 as the shifting frame 32 moves up and down. The output terminal of the limit switch 76 is electrically connected to the input terminal of each spray water pump 58. The limit switch 76 controls the operation of the spray water pump 58 using a method commonly used in the prior art. In order to accurately control the spray volume, a humidity sensor can be installed inside the gauze covering 212 to detect the humidity of the gauze covering 212.

[0037] The trigger assembly includes a second protruding plate 71, a second disassembly seat 72, a vertical rod 73, a protruding strip 74, a roller 77, a wheel frame 78, a sliding square rod 79, a pressing block 710, and a return spring 711. A sliding square rod 79 is slidably connected to a square hole on the side of the rectangular mounting frame 75 away from the displacement frame 32. One end of the sliding square rod 79, located within the rectangular mounting frame 75, is fixedly connected to the pressing block 710. The other end of the sliding square rod 79 is fixedly connected to the wheel frame 78. The wheel frame 78 is rotatably connected to the roller 77 via a wheel axle. A return spring 711 is sleeved on the part between the wheel frame 78 and the rectangular mounting frame 75. A second protruding plate 71 is integrally formed on the outer side of the fixed base frame 21. A second disassembly seat 72 is fixedly connected to the second protruding plate 71 by a protruding plate bolt. The bottom end of the vertical rod 73 is fixedly connected to the second disassembly seat 72. A protruding strip 74 is fixedly connected to the side of the vertical rod 73 near the displacement frame 32 at the position corresponding to the water spraying gap. The upper and lower ends of the protruding strip 74 are respectively provided with inclined surfaces. The roller 77 makes rolling contact with the side of the vertical rod 73 near the displacement frame 32.

[0038] In use, the up-and-down movement of the shifting frame 32 causes the rectangular mounting frame 75 to move up and down. At this time, the roller 77 rolls along the side of the vertical rod 73 near the shifting frame 32. When the shifting frame 32 corresponds to the water spraying gap, the roller 77 also corresponds to the convex rib 74. The convex rib 74 pushes the roller 77, the wheel frame 78, and the sliding square rod 79 along the square hole toward the limit switch 76. The pressing block 710 at the end of the sliding square rod 79 triggers the limit switch 76. The limit switch 76 controls the spray water pump 58 to work, spraying water onto the gauze covering 212 at the water spraying gap through the spray head 51. At this time, the return spring 711 is compressed. When the shifting frame 32 no longer corresponds to the water spraying gap, the roller 77 also moves away from the convex rib 74. As bar 74 continues to contact the side of vertical rod 73, the return spring 711 returns to its original position and extends, causing the pressing block 710 at the end of sliding square rod 79 to move away from limit switch 76. Limit switch 76 is no longer triggered, and spray pump 58 stops working, ensuring that water is sprayed only on the gauze covering 212 at the watering gap, and not sprayed on the outside of fixed plastic film sleeve 213 and movable plastic film sleeve 216. Therefore, fixed plastic film sleeve 213 and movable plastic film sleeve 216 are waterproof and will not absorb water to moisten bridge piers like gauze covering 212. After spraying, fixed plastic film sleeve 213 and movable plastic film sleeve 216 surround gauze covering 212, reducing water evaporation from gauze covering 212.
