Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a spray device for cooling large-volume concrete. Background Technology

[0002] In construction engineering, large-volume concrete is widely used, especially in key structures of large infrastructure such as bridges, dams, and high-rise buildings. However, after pouring, the internal temperature of large-volume concrete will rise significantly due to the large release of heat from cement hydration, generating thermal stress. This may cause the concrete to crack, affecting the integrity and service life of the structure. In order to effectively control the rise in internal temperature of large-volume concrete and reduce thermal stress, it is usually necessary to cool the concrete after pouring. This process requires the use of a spraying device.

[0003] Existing sprinkler systems are mostly composed of water pipes and nozzles. The nozzles are connected to one end of the water pipes, and the working process is as follows: the worker holds the water pipe and fills it with water, then aims the nozzle at the concrete to be sprayed. At this time, the water inside the pipe is sprayed onto the concrete surface through the nozzle, thereby achieving a cooling effect on the concrete.

[0004] Furthermore, existing spraying devices are generally ineffective and wasteful of water resources. If the spraying device cannot effectively control the water volume, it may cause water waste, especially in arid areas or when water resources are scarce. Moreover, existing spraying devices cannot monitor the internal temperature of concrete in real time, thus failing to spray the concrete at the appropriate temperature. Summary of the Invention

[0011] Furthermore, the temperature measuring mechanism also includes a chute, which is located on the side of the connecting pipe near the concrete column.

[0012] Furthermore, the clamping mechanism includes a positive and negative threaded rod, the two ends of which are rotatably connected to the interior of the lifting platform. A motor is fixedly connected to the outside of the lifting platform, and the output end of the motor passes through the lifting platform and is drivenly connected to one end of the positive and negative threaded rod. The two ends of the positive and negative threaded rod are provided with external threads in different directions.

[0017] The technical effects and advantages of the spray device for cooling large-volume concrete according to the present invention are as follows:

[0018] (1) Through the structural design of the intermittent mechanism and the baffle, the intermittent mechanism drives the baffle to move up and down continuously, so that the nozzle of the spray head is exposed intermittently, thereby achieving the function of intermittent spraying of the nozzle. Whenever the nozzle sprays water onto the surface of the concrete column, the baffle will block the nozzle again due to the influence of the intermittent mechanism. The water attached to the outside of the concrete column will flow down along the outside of the concrete column under the action of gravity, thereby compensating for the part that the nozzle has not yet sprayed due to the baffle blocking the nozzle. Thus, while saving water resources, the water resources are evenly attached to the outside of the concrete column, achieving the function of cooling.

[0019] (2) Through the structural design of the temperature sensor and temperature measuring mechanism, the internal temperature of the concrete column is monitored in a fully enclosed manner, and the measured value is more accurate. Once the expected value is exceeded, the temperature measuring mechanism will drive the temperature sensor to detach from the temperature measuring groove opened in the concrete column. The temperature sensor will transmit the value to the external computer, so that its nozzle can cool the concrete column, thereby improving the automation level of the device.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 - Figure 11 As shown, a spray device for cooling large-volume concrete includes a concrete column 1 and a support plate 2, and a pair of arc-shaped plates 3 disposed on the outside of the concrete column 1. Multiple sets of nozzles 4 are installed on the inner sides of each pair of arc-shaped plates 3. The multiple sets of nozzles 4 are connected to external water pipes. A fixing plate 5 is fixedly connected to the top of the support plate 2. A motor 6 is fixedly connected to the outer side of the fixing plate 5. The motor 6 is electrically connected to an external computer. The output end of the motor 6 passes through the fixing plate 5 and is connected to a roller 7. A pair of steel wire ropes 8 are fixedly connected to the outer side of the roller 7. A first roller 9 and a second roller 10 are slidably connected to the outer sides of a pair of wire ropes 8. A fixed frame 11 is rotatably connected to the outer sides of the first roller 9 and the second roller 10. A support plate 12 is fixedly connected to the end of the fixed frame 11 away from the first roller 9 and the second roller 10. The support plate 12 is fixedly connected to the top of the support plate 2. A lifting platform 13 is fixedly connected to the end of a pair of wire ropes 8 away from the winding roller 7. A guide rod 14 is slidably connected inside the lifting platform 13. A pair of guide rods 14 are fixedly connected to the top of the support plate 2. The system also includes...

[0036] A clamping mechanism is provided inside the lifting platform 13, which is used to move a pair of arc-shaped plates 3;

[0037] An intermittent mechanism is provided at the top of the support plate 2. The intermittent mechanism includes a pair of first connecting plates 15, a pair of connecting rods 16 are fixedly connected between the pair of first connecting plates 15, a first rack 17 is slidably connected to the outer side of the pair of connecting rods 16, a first gear 18 is provided on one side of the first rack 17, and a baffle 19 is attached to the side of the multiple sets of nozzles 4 away from the arc plate 3. The intermittent mechanism is used to intermittently move the baffle 19.

[0038] A temperature measuring mechanism is installed inside the concrete column 1. The concrete column 1 has a temperature measuring groove inside, and a temperature measuring device 20 is installed inside the temperature measuring groove. The temperature measuring device 20 is electrically connected to an external computer, and a connecting pipe 21 is fixed to the outside of the temperature measuring device 20.

[0039] Existing sprinkler systems are generally ineffective and wasteful of water resources. If the sprinkler system cannot effectively control the water volume, it can lead to significant water waste, especially in arid regions or when water is scarce. Furthermore, existing sprinkler systems cannot monitor the internal temperature of the concrete in real time to ensure proper spraying. To address these issues, this invention first uses a clamping mechanism to move a pair of arc-shaped plates 3 in opposite directions. Then, the pair of arc-shaped plates 3 are moved to the outside of the concrete column 1. The clamping mechanism then brings the pair of arc-shaped plates 3 closer together. This causes multiple sets of nozzles 4 to approach the concrete column 1, preventing incomplete spraying due to excessive distance between the nozzles 4 and the concrete column 1. Initially, the lifting platform 13 is positioned at the lower half of the concrete column 1, and the lifting platform 13, through a temperature measuring mechanism, positions the temperature sensor 20 inside the concrete column 1. Inside the temperature measuring tank, which is half the thickness of the concrete column 1, when the temperature sensor 20 detects that the temperature inside the tank exceeds 50°C, it transmits the information to an external computer. The external computer then controls the motor 6 to run. During operation, the motor 6 drives the roller 7 to wind the steel wire rope 8. The steel wire rope 8 then pulls the lifting platform 13 upwards along the first roller 9 and the second roller 10. As the lifting platform 13 moves upwards, it drives the connecting pipe 21 to move via the temperature measuring mechanism. The connecting pipe 21 then drives the temperature sensor 20 to detach from the temperature measuring tank, preventing the cooling of the water during subsequent spraying from affecting the temperature sensor 20's measurement values. Simultaneously, the movement of the lifting platform 13 drives the arc plate 3 and the nozzle 4 upwards via the clamping mechanism. The nozzle 4 then sprays the outside of the concrete column 1. The upward movement of the lifting platform 13 also drives the first gear 18 above it to move upwards. During this upward movement, the first gear 18 meshes with the first rack 17, and the first gear 18 then... Figure 5 From a perspective of rotation, the first connecting plate 15 rotates counterclockwise, which in turn drives the intermittent mechanism to operate. The intermittent mechanism then drives the baffle 19 to move up and down continuously, intermittently exposing the nozzles of the spray head 4, thus achieving the function of intermittent spraying by the spray head 4. Whenever the spray head 4 sprays water onto the surface of the concrete column 1, the baffle 19, affected by the intermittent mechanism, will block the spray head 4 again. The water adhering to the outside of the concrete column 1 will flow downward along the outside of the concrete column 1 under the action of gravity, thereby compensating for the area not yet sprayed by the spray head 4 due to the baffle 19 blocking the spray head 4. This saves water resources and evenly coats the outside of the concrete column 1, achieving the function of cooling.

[0040] like Figure 4 - Figure 7As shown, the intermittent mechanism also includes a gear rod 22, which meshes with the interior of the first gear 18. Both ends of the gear rod 22 are rotatably connected to a second connecting plate 23, which is fixedly attached to the top of the lifting platform 13. A first sprocket 24 meshes with the outer side of the gear rod 22. A second sprocket 25 is located at the end of the first sprocket 24 near the concrete column 1. A chain 26 is wound around the outer sides of the first sprocket 24 and the second sprocket 25. A transmission rod is fixedly connected inside the second sprocket 25. Both ends of the transmission rod are rotatably connected to a third connecting plate 27. An L-shaped... Plate 28, the L-shaped plate 28 is fixed to the top of the arc plate 3, a second gear 29 is fixed to the outside of the transmission rod, the second gear 29 has a notch on the outside, a second rack 30 meshes with the outside of the second gear 29, the bottom end of the second rack 30 is fixed to the top of the baffle 19, a pair of limiting plates 31 are fixed to the top of the baffle 19, a first limiting rod 32 is slidably connected inside the pair of limiting plates 31, the bottom end of the first limiting rod 32 is fixed to the top of the arc plate 3, a baffle 33 is fixed to the top of the first limiting rod 32, and a first spring 34 is fixed between the limiting plate 31 and the baffle 33.

[0041] baffle 19 Figure 5 When rotated counterclockwise, it drives the gear rod 22 to rotate counterclockwise synchronously. The rotation of the gear rod 22, in turn, drives the first sprocket 24 to rotate. It should be noted that when moving the pair of arc-shaped plates 3, the position of the first sprocket 24 needs to be manually adjusted to ensure that the first sprocket 24 and the second sprocket 25 are on the same straight line. At this time, the first sprocket 24 drives the second sprocket 25 to rotate via the chain 26. The second sprocket 25 then drives the second gear 29 via the transmission rod. Figure 6 As the viewing angle rotates clockwise, the second gear 29, through the second rack 30, drives the baffle 19 upward. As the baffle 19 moves upward, it disengages from the nozzle 4, allowing the nozzle 4 to spray water onto the outside of the concrete column 1. Simultaneously, the baffle 19, moving upward, causes the limiting plate 31 to compress the first spring 34. The first spring 34 deforms under stress, generating elastic potential energy. As the second gear 29 continues to rotate, when its notch reaches the second rack 30, the meshing between the second gear 29 and the second rack 30 ends, and the first spring 34 is no longer under stress. The first spring 34 instantly releases its elastic potential energy, pushing the baffle 19 back to its original position via the limiting plate 31. The baffle 19 then blocks the nozzle 4 again, preventing it from spraying water onto the surface of the concrete column 1. With the rotation of the second gear 29, the baffle 19 continuously repeats this action, constantly exposing and blocking the nozzle 4, thus achieving the function of intermittent spraying by the nozzle 4.

[0042] like Figure 8 - Figure 10 As shown, the temperature measuring mechanism also includes a slide groove 35, which is located on the side of the connecting pipe 21 near the concrete column 1. A baffle tube 36 is slidably connected inside the slide groove 35. The baffle tube 36 is made of high-temperature resistant rubber. A pair of second springs 37 are fixedly connected between the baffle tube 36 and the slide groove 35. The baffle tube 36 is in contact with the outer side of the concrete column 1. A pair of guide plates 38 are fixedly connected to the outer side of the connecting pipe 21. A second limiting rod 39 is slidably connected inside each of the guide plates 38. A concave plate 40 is fixedly connected to both ends of the second limiting rod 39. The concave plate 40 is fixedly connected to the top of the support plate 2. A third spring 41 is fixedly connected between the guide plate 38 and the concave plate 40. A first magnetic block 42 is fixedly connected to the end of the connecting pipe 21 away from the temperature measuring device 20. A second magnetic block 43 is fixedly connected to the top of the lifting platform 13. The first magnetic block 42 and the second magnetic block 43 are like poles and repel each other.

[0043] In the initial state, the lifting platform 13 moves the second magnetic block 43 within the magnetic force range of the first magnetic block 42. The second magnetic block 43 pushes the connecting pipe 21 towards the concrete column 1 through the first magnetic block 42. The movement of the connecting pipe 21 pulls the third spring 41 through the guide plate 38, causing the third spring 41 to deform and store potential energy. When the connecting pipe 21 moves towards the concrete column 1, the baffle 36 inside the slide 35 will first contact and squeeze the concrete column 1. The force of the baffle 36 is transmitted to the second spring 37, causing the second spring 37 to deform and generate elastic potential energy. It should be noted that the magnetic force between the second magnetic block 43 and the first magnetic block 42 can overcome the elastic coefficients of the third spring 41 and the second spring 37, as well as the weight of the thermometer 20, the connecting pipe 21, and the baffle 36. At this time, the baffle 36 is tightly attached to the outside of the concrete column 1. The baffle 36 is made of high-temperature resistant rubber, ensuring the safety of the thermometer 20. When inside the temperature measuring tank, the thermometer 20 is isolated from the outside temperature. When the thermometer 20 senses that the temperature inside the measuring tank exceeds 50°C, it transmits the information to an external computer. The external computer controls the motor 6 to run, which eventually moves the lifting platform 13 upward. When the lifting platform 13 moves upward, it drives the second magnetic block 43 upward, thus breaking away from the magnetic force range of the first magnetic block 42. The third spring 41 stops being stressed and releases its energy, pulling the connecting pipe 21 away from the concrete column 1 through the guide plate 38. The connecting pipe 21 then drives the thermometer 20 to leave the inside of the temperature measuring tank. As the connecting pipe 21 moves, the pressure on the second spring 37 gradually ends, and the second spring 37 releases its elastic potential energy, pushing the baffle pipe 36 towards the concrete column 1 to protect the outside of the thermometer 20 and prevent water from dripping directly onto the outside of the thermometer 20, affecting the temperature reading.

[0044] like Figure 3 As shown, the clamping mechanism includes a positive and negative threaded rod 44. The two ends of the positive and negative threaded rod 44 are rotatably connected to the inside of the lifting platform 13. A motor 45 is fixedly connected to the outside of the lifting platform 13. The output end of the motor 45 passes through the lifting platform 13 and is drivenly connected to one end of the positive and negative threaded rod 44. The two ends of the positive and negative threaded rod 44 are provided with external threads in different directions. The two ends of the positive and negative threaded rod 44 are respectively threadedly connected to a pair of arc plates 3. A third limiting rod 46 is fixedly connected to the inside of the lifting platform 13. The third limiting rod 46 passes through a pair of arc plates 3.

[0045] When the concrete column 1 is fitted inside a pair of curved plates 3, the motor 45 is started first. When the motor 45 is running, it drives the positive and negative threaded rods 44 to rotate. When the positive and negative threaded rods 44 rotate, they will drive the pair of curved plates 3 to move in opposite directions. When the distance between the pair of curved plates 3 is greater than the width of the concrete column 1, the motor 45 stops. At this time, the pair of curved plates 3 are moved to both sides of the concrete column 1. Then the motor 45 is started again. The motor 45 rotates in the opposite direction. The motor 45 then drives the positive and negative threaded rods 44 to rotate in the opposite direction. The positive and negative threaded rods 44 will then drive the pair of curved plates 3 to move closer together, bringing the multiple sets of nozzles 4 inside the curved plates 3 closer to the concrete column 1.

[0046] like Figure 6 and Figure 11 As shown, a first support frame 47 is fixedly connected to the outer side of the lifting platform 13. A tooth removal mechanism is provided at the end of the first support frame 47 away from the lifting platform 13. The tooth removal mechanism is used to move the first rack 17.

[0047] When the lifting platform 13 moves upward, the second gear 29... Figure 6 By rotating the viewing angle clockwise, it can be ensured that the second rack 30 drives the baffle 19 to move upward first, and then downward. Then, when the lifting platform 13 moves downward, the second gear 29... Figure 6When the viewing angle rotates counterclockwise, the second rack 30 will drive the baffle 19 to move downwards. However, the baffle 19 cannot move downwards due to the obstruction of the second rack 30. To solve the above problem, in this embodiment of the invention, during the upward movement of the first gear 18, the first gear 18 and the first rack 17 are in a meshing state. As the first gear 18 continues to move upwards, when the first gear 18 disengages from the first rack 17, the lifting platform 13 will drive the de-gear mechanism through the first support frame 47. The de-gear mechanism will then drive the first rack 17 to move laterally. At this time, when the first gear 18 moves downwards to reset, the first gear 18 will not contact and mesh with the first rack 17. Therefore, the second gear 29 will not rotate, thus avoiding the above problem. When the first gear 18 resets to a certain distance, the lifting platform 13 will drive the first rack 17 to reset laterally again through the de-gear mechanism. At this time, during the upward movement of the first gear 18, the first gear 18 will mesh with the first rack 17 again, and the second gear 29 will rotate.

[0048] like Figure 6 and Figure 11 As shown, the tooth removal mechanism includes a first inclined block 48, which is fixed to the end of the first support frame 47 away from the lifting platform 13. A second inclined block 49 is fixed to the side of the first rack 17 near the first inclined block 48. A second support frame 50 is provided on the side of the first rack 17 away from the first inclined block 48. One end of the second support frame 50 is fixed to the outside of the lifting platform 13. A third inclined block 51 is fixed to the end of the second support frame 50 away from the lifting platform 13. A fourth inclined block 52 is attached to the end of the third inclined block 51 away from the second support frame 50. The fourth inclined block 52 is fixed to the side of the first rack 17 near the third inclined block 51.

[0049] When the lifting platform 13 moves upward to a certain distance, the lifting platform 13 will drive the first inclined block 48 to press the second inclined block 49 through the first support frame 47. The inclined surface of the second inclined block 49 will move laterally due to the force. The movement of the second inclined block 49 will drive the first rack 17 to move synchronously along the connecting rod 16. At this time, the first rack 17 and the first gear 18 will disengage. When the lifting platform 13 drives the first gear 18 set above to move downward to reset, the first gear 18 will not rotate, and the second gear 29 will not rotate. As the lifting platform 13 moves downward to a certain distance, the lifting platform 13 will eventually drive the third inclined block 51 to press the inclined surface of the fourth inclined block 52 through the second support frame 50. The force on the fourth inclined block 52 will drive the first rack 17 to move laterally to reset. At this time, when the first gear 18 moves upward, the first gear 18 and the first rack 17 will be engaged again. It should be noted that during the process of the first rack 17 resetting laterally, the first rack 17 will not contact the first gear 18.

[0050] like Figure 12 As shown, a reset spring is installed on the side of the multiple sets of nozzles 4 near the arc plate 3, and a fifth inclined block 53 is fixed to the top of each set of nozzles 4. The fifth inclined block 53 is attached to the side of the baffle 19 near the arc plate 3.

[0051] When the distance between the nozzle 4 and the concrete column 1 is too far, the spraying of the nozzle 4 will be greatly affected by wind speed and other factors, resulting in inaccurate spraying direction. In order to solve the above problem, in the initial state, the baffle 19 presses the inclined surface of the fifth inclined block 53, and the fifth inclined block 53 drives the nozzle 4 to approach the arc plate 3, so that the return spring between the nozzle 4 and the arc plate 3 is in a compressed state. When the baffle 19 moves upward, the compression of the fifth inclined block 53 by the baffle 19 ends, and the return spring releases its elastic potential energy instantly, pushing the nozzle 4 to approach the concrete column 1. It should be noted that when the nozzle 4 approaches the concrete column 1, it will not hit the outside of the concrete column 1.

[0052] like Figure 6 and Figure 7 As shown, a measuring disc 54 is attached to the outer side of the first sprocket 24, and a fixing rod 55 is fixed to the bottom end of the measuring disc 54. The end of the fixing rod 55 away from the measuring disc 54 is fixed to the outer side of the L-shaped plate 28.

[0053] When a pair of arc-shaped plates 3 move, they will synchronously drive the L-shaped plate 28 to move. At this time, the second sprocket 25 set above the L-shaped plate 28 will also move. In order to move the first sprocket 24 and ensure that the first sprocket 24 and the second sprocket 25 are always on the same straight line, and to ensure the normal rotation of the chain 26, in the embodiment of the present invention, when the L-shaped plate 28 moves, it will synchronously drive the fixed rod 55 to move. The fixed rod 55 will then push the first sprocket 24 to move through the measuring plate 54, thereby effectively solving the above-mentioned problems.

[0054] Working Principle: Existing sprinkler systems are generally ineffective and wasteful of water resources. If the sprinkler system cannot effectively control the water volume, it may lead to water waste, especially in arid regions or when water resources are scarce. Furthermore, existing sprinkler systems cannot monitor the internal temperature of the concrete in real time to ensure appropriate spraying. To address these issues, this invention first uses a clamping mechanism to move a pair of arc-shaped plates 3 in opposite directions. Then, the pair of arc-shaped plates 3 are moved to the outside of the concrete column 1. The clamping mechanism then brings the pair of arc-shaped plates 3 closer together. This causes multiple sets of nozzles 4 to approach the concrete column 1, preventing incomplete spraying if the distance between the nozzles 4 and the concrete column 1 is too great. Initially, the lifting platform 13 is positioned at the lower half of the concrete column 1. At this time, the lifting platform 13 uses a temperature measuring mechanism to move the temperature sensor 20 to the concrete column. Inside the temperature measuring groove of column 1, which is half the thickness of the concrete column 1, when the temperature sensor 20 detects that the temperature inside the temperature measuring groove exceeds 50°C, the temperature sensor 20 transmits the information to an external computer. The external computer then controls the motor 6 to run. When the motor 6 runs, it drives the roller 7 to wind the steel wire rope 8. The steel wire rope 8 then pulls the lifting platform 13 upward along the first roller 9 and the second roller 10. During the upward movement of the lifting platform 13, the lifting platform 13 drives the connecting pipe 21 to move through the temperature measuring mechanism. The connecting pipe 21 then drives the temperature sensor 20 to detach from the temperature measuring groove, preventing the cooling of the water during subsequent spraying from affecting the measurement value of the temperature sensor 20. The movement of the lifting platform 13 also simultaneously drives the arc plate 3 and the nozzle 4 to move upward through the clamping mechanism. The nozzle 4 then sprays the outside of the concrete column 1. The upward movement of the lifting platform 13 also drives the first gear 18 above it to move upward. During the upward movement of the first gear 18, it meshes with the first rack 17, and the first gear 18 then... Figure 5 From a perspective of rotation, the first connecting plate 15 rotates counterclockwise, causing the intermittent mechanism to operate. This intermittent mechanism, in turn, causes the baffle 19 to move up and down continuously, intermittently exposing the nozzles of the spray head 4, thus achieving the function of intermittent spraying. Whenever the spray head 4 sprays water onto the surface of the concrete column 1, the baffle 19, influenced by the intermittent mechanism, blocks the spray head 4 again. Water adhering to the outside of the concrete column 1, under the influence of gravity, flows downwards along the outer side of the concrete column 1, thus compensating for the areas not yet sprayed by the baffle 19. This saves water resources while evenly distributing water to the outside of the concrete column 1, achieving a cooling function. The baffle 19... Figure 5When rotated counterclockwise, it drives the gear rod 22 to rotate counterclockwise synchronously. The rotation of the gear rod 22, in turn, drives the first sprocket 24 to rotate. It should be noted that when moving the pair of arc-shaped plates 3, the position of the first sprocket 24 needs to be manually adjusted to ensure that the first sprocket 24 and the second sprocket 25 are on the same straight line. At this time, the first sprocket 24 drives the second sprocket 25 to rotate via the chain 26. The second sprocket 25 then drives the second gear 29 via the transmission rod. Figure 6As the viewing angle rotates clockwise, the second gear 29, through the second rack 30, drives the baffle 19 upward. As the baffle 19 moves upward, it disengages from the nozzle 4, allowing the nozzle 4 to spray water onto the outside of the concrete column 1. Simultaneously, the baffle 19, moving upward, causes the limiting plate 31 to compress the first spring 34. The first spring 34 deforms under stress, generating elastic potential energy. As the second gear 29 continues to rotate, when its notch reaches the second rack 30, the meshing between the second gear 29 and the second rack 30 ends, and the first spring 34 releases its elastic potential energy, pushing the baffle 19 back to its original position via the limiting plate 31. The baffle 19 then repositions the nozzle. With the second gear 29 rotating, the baffle 19 repeatedly performs the above actions, constantly exposing and blocking the nozzle 4, thus achieving the function of intermittent spraying by the nozzle 4. In the initial state, the lifting platform 13 drives the second magnetic block 43 to be within the magnetic force range of the first magnetic block 42. The second magnetic block 43 pushes the connecting pipe 21 towards the concrete column 1 through the first magnetic block 42. The movement of the connecting pipe 21 will pull the third spring 41 through the guide plate 38, causing the third spring 41 to deform and store force. When the connecting pipe 21 moves towards the concrete column 1, the baffle 36 inside the slide 35 will first contact and squeeze the concrete column 1. The force of the baffle 36 is transmitted to the second magnetic block 42. Spring 37 causes the second spring 37 to deform under force and generate elastic potential energy. It should be noted that the magnetic force between the second magnetic block 43 and the first magnetic block 42 can overcome the elastic coefficients of the third spring 41 and the second spring 37, as well as the weight of the thermometer 20, the connecting pipe 21, and the baffle 36. At this time, the baffle 36 is tightly attached to the outside of the concrete column 1. The baffle 36 is made of high-temperature resistant rubber, ensuring that the thermometer 20 is isolated from the outside temperature when it is inside the temperature measuring tank. When the thermometer 20 senses that the temperature inside the temperature measuring tank exceeds 50°C, the thermometer 20 transmits the information to the external computer. The external computer controls the motor 6 to run, and the motor 6 ultimately moves the lifting platform 13 upward. When the second magnetic block 43 moves upward, it will break away from the magnetic field of the first magnetic block 42. The third spring 41 will then release its energy, pulling the connecting pipe 21 away from the concrete column 1 via the guide plate 38. The connecting pipe 21 will then disengage the thermometer 20 from the inside of the temperature measuring tank. As the connecting pipe 21 moves, the pressure on the second spring 37 gradually decreases, releasing its elastic potential energy and pushing the baffle pipe 36 towards the concrete column 1, protecting the outside of the thermometer 20 and preventing water from dripping directly onto its exterior, thus affecting the temperature reading. When the concrete column 1 is fitted inside the pair of arc-shaped plates 3, the motor 45 is started first.When motor 45 is running, it drives the positive and negative threaded rods 44 to rotate. As the threaded rods 44 rotate, they cause a pair of arc-shaped plates 3 to move in opposite directions. When the distance between the pair of arc-shaped plates 3 is greater than the width of the concrete column 1, motor 45 stops. At this point, the pair of arc-shaped plates 3 are moved to both sides of the concrete column 1. Then, motor 45 is restarted, rotating in the opposite direction. Motor 45 then drives the positive and negative threaded rods 44 to rotate in the opposite direction, causing the pair of arc-shaped plates 3 to move closer together. This brings the multiple sets of nozzles 4 inside the arc-shaped plates 3 closer to the concrete column 1. When the lifting platform 13 moves upward, the second gear 29... Figure 6 By rotating the viewing angle clockwise, it can be ensured that the second rack 30 drives the baffle 19 to move upward first, and then downward. Then, when the lifting platform 13 moves downward, the second gear 29... Figure 6When the viewing angle rotates counterclockwise, the second rack 30 will cause the baffle 19 to move downwards. However, the baffle 19 cannot move downwards due to the obstruction of the second rack 30. To solve the above problem, in this embodiment of the invention, during the upward movement of the first gear 18, the first gear 18 and the first rack 17 are in a meshing state. As the first gear 18 continues to move upwards, when the first gear 18 disengages from the first rack 17, the lifting platform 13 will drive the tooth-removing mechanism through the first support frame 47. The tooth-removing mechanism will then drive the first rack 17 to move laterally. At this time, when the first gear 18 moves downwards to reset, the first gear 18 will not contact and mesh with the first rack 17. Therefore, the second gear 29 will not rotate, thus avoiding... To address the aforementioned issues, after the first gear 18 resets to a certain distance, the lifting platform 13, through the tooth-disengaging mechanism, drives the first rack 17 to reset laterally. At this time, during the upward movement of the first gear 18, it meshes with the first rack 17 again, causing the second gear 29 to rotate. When the lifting platform 13 moves upward to a certain distance, it drives the first inclined block 48 to press against the second inclined block 49 via the first support frame 47. The inclined surface of the second inclined block 49, under pressure, moves laterally. This movement of the second inclined block 49 drives the first rack 17 to move synchronously along the connecting rod 16. At this point, the first rack 17 and the first gear 18 disengage. When the lifting platform 13 drives the upper-mounted first gear 18 to move downward to reset, the first gear 17... 8 will not rotate, and the second gear 29 will also not rotate. As the lifting platform 13 moves downward to a certain distance, the lifting platform 13 will eventually drive the third inclined block 51 to press the inclined surface of the fourth inclined block 52 through the second support frame 50. The force on the fourth inclined block 52 will drive the first rack 17 to move laterally and reset. At this time, when the first gear 18 moves upward, the first gear 18 and the first rack 17 will be in a meshing state again. It should be noted that during the process of the first rack 17 resetting laterally, the first rack 17 will not contact the first gear 18. When the distance between the nozzle 4 and the concrete column 1 is too far, the spraying of the nozzle 4 will be greatly affected by wind speed, resulting in inaccurate spraying direction of the nozzle 4. In order to solve the above problems, in the initial state, the block Plate 19 presses against the inclined surface of the fifth inclined block 53, causing the nozzle 4 to approach the arc-shaped plate 3. This compresses the return spring between the nozzle 4 and the arc-shaped plate 3. When the baffle 19 moves upward, the pressure on the fifth inclined block 53 ends, and the return spring instantly releases its elastic potential energy, pushing the nozzle 4 closer to the concrete column 1. It should be noted that the nozzle 4 will not collide with the outer side of the concrete column 1 when it approaches. When the pair of arc-shaped plates 3 move, they will simultaneously drive the L-shaped plate 28 to move. At this time, the second sprocket 25 above the L-shaped plate 28 will also move. In order to move the first sprocket 24 and ensure that the first sprocket 24 and the second sprocket 25 are always on the same straight line, the chain 26 will rotate normally.In this embodiment of the invention, the L-shaped plate 28 moves synchronously with the fixed rod 55, which in turn drives the first sprocket 24 to move via the measuring plate 54, thus effectively solving the aforementioned problems.
