Description

Technical Field

[0001] This application relates to the field of concrete curing technology, and in particular to an intelligent spray curing system for airport concrete pavement construction. Background Technology

[0002] After the construction of the concrete pavement at the airport is completed, effective maintenance is required to ensure the quality and service life of the concrete pavement.

[0003] In traditional maintenance, because concrete pavement has a large surface area, water trucks are usually used to water the concrete pavement to create certain humidity and temperature conditions, so that the freshly poured concrete can harden normally or accelerate and increase its strength.

[0004] In related technologies, workers will lay a layer of geotextile on the concrete pavement. Geotextile is a permeable synthetic material that can reduce the evaporation rate of water on the concrete pavement while ensuring that the concrete pavement has a certain level of humidity and temperature.

[0005] However, the watering of concrete pavements by sprinkler trucks depends on worker operation, which can easily lead to uneven watering. Furthermore, after laying geotextile, workers cannot visually inspect the moisture level on the concrete pavement, resulting in both water waste and uneven curing. Consequently, some areas of the concrete pavement may fail to meet structural strength standards. Therefore, the effectiveness of concrete pavement curing in related technologies needs further improvement. Summary of the Invention

[0006] To improve the curing effect of concrete pavement, this application provides an intelligent spray curing system for airport concrete pavement construction.

[0007] The intelligent spray curing system for airport concrete pavement construction provided in this application adopts the following technical solution:

[0008] An intelligent spray curing system for airport concrete pavement construction includes a mobile vehicle, a control and display module, a linkage component, a spraying component, and a humidity sensing component.

[0009] The linkage component includes a mounting plate disposed on the mobile vehicle, a rotating platform disposed on the mounting plate, a first rotating support disposed on the rotating platform, and a second rotating support rotatably disposed on the first rotating support.

[0010] The spraying assembly is mounted on the mobile vehicle, the first rotating support, and the second rotating support, and is used to water the concrete pavement.

[0011] The humidity sensing component includes a geotextile that can be laid on a concrete pavement, multiple humidity sensors arranged at equal intervals on one side of the geotextile, a second communication unit disposed on the geotextile, a conditioning circuit module and an analog-to-digital converter built into the second communication unit.

[0012] The control and display module is communicatively connected to the rotating platform, the first rotating support, the second rotating support, the spray assembly, and the second communication unit, respectively. The second communication unit, the analog-to-digital converter, the conditioning circuit module, and the humidity sensor are connected in sequence.

[0013] By adopting the above technical solution, when curing concrete pavement, geotextile is first laid on the concrete pavement to enhance its insulation effect. Then, multiple humidity sensors on the geotextile detect the humidity at various points on the concrete pavement. Next, a mobile vehicle is moved to one side of the concrete pavement, and the rotating platform, first rotating support, and second rotating support are rotated sequentially, thus unfolding the entire linkage assembly to deploy the spraying assembly. The spraying assembly then pours water onto the concrete pavement, which absorbs the water to harden and increase its strength. Simultaneously, as the water on the concrete pavement decreases, multiple humidity sensors continuously monitor the humidity under the geotextile to obtain a humidity analog signal. The conditioning circuit module then conditions the humidity analog signal, and the analog-to-digital converter converts it into a humidity digital signal. Finally, the second communication unit sends the humidity digital signal to the control and display module, allowing staff to confirm the humidity status at various points on the concrete pavement. Because the humidity status of the concrete pavement can be obtained in real time, situations of insufficient or wasted water can be effectively reduced, thereby significantly improving the curing effect of the concrete pavement.

[0014] The humidity information of various parts of the concrete pavement is converted into a temperature range by the conditioning circuit module.

[0015] Optionally, the conditioning circuit module includes a sampling circuit unit, a voltage conversion unit, a low-pass filter unit, a drive isolation unit, and a limiting protection unit connected in sequence; the sampling circuit unit is connected to the humidity sensor, and the limiting protection unit is connected to the second communication unit.

[0016] By adopting the above technical solution, the sampling circuit unit can convert the current signal of the humidity sensor into a voltage signal, the voltage conversion unit can adjust the converted voltage signal to meet the input voltage requirements of the second communication unit, the low-pass filter unit can eliminate power frequency interference and high frequency interference on the analog channel, the drive isolation unit can achieve impedance matching of the input channel, and the limiting protection unit can keep the input voltage of the analog-to-digital converter within the specified voltage range, thereby protecting the A / D conversion channel.

[0017] Optionally, the control display module includes a controller, a touch screen and a first communication unit respectively communicated with the controller; the touch screen is disposed on the mobile vehicle, the controller and the first communication unit are built into the touch screen, and the first communication unit is respectively communicated with the second communication unit, the rotating platform, the first rotating support, the second rotating support, the spray assembly and the second communication unit.

[0018] By adopting the above technical solution, the controller can control the touch screen display, allowing operators to perform operations through the touch screen. The controller can also control the rotation of the rotating platform, the first rotating support, and the second rotating support via the first communication unit, and control the spray system to water the system. The communication connection between the first and second communication units enables the transmission of humidity information.

[0019] Optionally, the rotating platform includes a rotating motor, a driving gear, a driven gear, and a rotating circular plate; the rotating motor is mounted on the mounting plate and is communicatively connected to the first communication unit; the driving gear is coaxially mounted on the driving end of the rotating motor; the driven gear is rotatably mounted on the mounting plate and meshes with the driving gear; the rotating circular plate is coaxially mounted on the driven gear; and the first rotating support is mounted on the rotating circular plate.

[0020] By adopting the above technical solution, when the drive end of the rotating motor rotates, it can drive the drive gear to rotate, the drive gear can drive the driven gear to rotate, thereby driving the rotating disc to rotate, and then the rotating disc can drive the first rotating support to rotate.

[0021] Optionally, the first rotating support includes a support arm, a first drive motor, and a first rotating arm; one end of the support arm is horizontally disposed on the rotating circular plate, and the other end is rotatably connected to one end of the first rotating arm; the first drive motor is disposed on the support arm and is used to rotate the first rotating arm; the first drive motor is communicatively connected to the first communication unit; and the second rotating support is rotatably disposed on the first rotating arm.

[0022] By adopting the above technical solution, when the drive end of the first drive motor rotates, it can drive the first rotating arm to rotate. When the support arm extends from one side of the mobile carrier, the first rotating arm extends from the support arm, thereby driving the second rotating support to extend from the mobile carrier, so as to provide support for the entire spray assembly.

[0023] Optionally, the second rotating support includes a second rotating arm rotatably mounted on the first rotating arm at one end and a second drive motor mounted on the second rotating arm. The second drive motor is communicatively connected to the first communication unit and is used to rotate the second rotating arm.

[0024] By adopting the above technical solution, when the drive end of the second drive motor rotates, it can drive the second rotating arm on the first rotating arm to rotate, thereby causing the second rotating arm to extend out from the first rotating arm.

[0025] Optionally, the spray assembly includes a water tank, a water pump, pipe fittings, and multiple spray heads; the water tank and the water pump are mounted on the mobile carrier, the pipe fittings are mounted on the first rotating arm and the second rotating arm, the multiple spray heads are equidistantly mounted on the pipe fittings, and the water pump is communicatively connected to the first communication unit.

[0026] By adopting the above technical solution, when the controller controls the water pump to work through the first communication unit, the water in the water tank is pumped by the water pump and sprayed out through multiple spray heads via pipe fittings, thereby achieving watering of the concrete pavement. Since the multiple spray heads are set at equal intervals, the uniformity of spraying is greatly improved, thus effectively improving the curing effect of the concrete pavement.

[0027] Optionally, the spray assembly may further include a Y-type filter disposed between the water tank and the water pump.

[0028] By adopting the above technical solution, the Y-type filter can filter out impurities, thereby reducing the possibility of impurities damaging the water pump and effectively increasing the service life of the water pump.

[0029] Optionally, the spray assembly further includes a pre-pump solenoid valve and a post-pump solenoid valve that are respectively connected to the first communication unit. The pre-pump solenoid valve is disposed between the water tank and the water pump, and the post-pump solenoid valve is disposed between the water pump and the pipe fitting.

[0030] By adopting the above technical solution, closing the solenoid valve before the pump can prevent water loss from the water tank during pump maintenance. Installing both the solenoid valve after the pump and the solenoid valve before the pump 42 also facilitates the adjustment of the pump's output and inflow rates, reducing the possibility of the pump exceeding its capacity due to excessive flow per unit time.

[0031] Optionally, the pipe fitting includes a first corrugated hose, a first main water pipe, a second corrugated hose, and a second main water pipe connected in sequence; the first corrugated hose is connected to the water pump, the first main water pipe is disposed on the first rotating arm, the second main water pipe is disposed on the second rotating arm, and a plurality of the spray heads are disposed on the first main water pipe and the second main water pipe.

[0032] By adopting the above technical solution, when the water pump is working, water can sequentially pass through the first corrugated hose, the first main water pipe, the second corrugated hose, and the second main water pipe, and finally be sprayed out by multiple spray heads. The first corrugated hose facilitates the corresponding rotation of the first main water pipe when the first rotating arm rotates. Similarly, the second corrugated hose facilitates the corresponding rotation of the second main water pipe when the second rotating arm rotates.

[0033] In summary, the beneficial technical effects of this application are as follows: when curing concrete pavement, workers can determine the humidity of the concrete pavement in real time, thereby determining the time for the next watering. This reduces water waste while improving the uniformity of curing, thus effectively improving the curing effect of concrete pavement. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0040] This application discloses an intelligent spray curing system for airport concrete pavement construction.

[0041] Reference Figure 1 and Figure 3 An intelligent spray curing system for airport concrete pavement construction includes a mobile vehicle 1, a control and display module 2, a linkage component 3, a spraying component 4, and a humidity sensing component 5.

[0042] The control and display module 2 and the linkage component 3 are both mounted on the mobile vehicle 1, the sprinkler component 4 is mounted on the linkage component 3, and the humidity sensing component 5 is laid on the concrete pavement. The control and display module 2 is communicatively connected to the linkage component 3, the sprinkler component 4, and the humidity sensing component 5.

[0043] Reference Figure 2 and Figure 3 The control and display module 2 includes a controller 21, a touch screen display 22, and a first communication unit 23. The touch screen display 22 is installed in the driver's cabin of the mobile vehicle 1, and the controller 21 and the first communication unit 23 are built into the touch screen display 22. The controller 21 is communicatively connected to the touch screen display 22 and the first communication unit 23, respectively, and the first communication unit 23 is communicatively connected to the linkage component 3, the spray component 4, and the humidity sensing component 5, respectively.

[0044] Reference Figure 2 and Figure 3 The linkage component 3 includes a mounting plate 31, a rotating platform 32, a first rotating support 33, and a second rotating support 34. The mounting plate 31 is horizontally fixed to the rear of the mobile carrier 1 and is located on one side of the mobile carrier 1. The rotating platform 32 is mounted on the mounting plate 31, the first rotating support 33 is mounted on the rotating platform 32, and the second rotating support 34 is mounted on the first rotating support 33. The rotating platform 32, the first rotating support 33, and the second rotating support 34 are all communicatively connected to the first communication unit 23.

[0045] Reference Figure 3 and Figure 4The rotating platform 32 includes a rotating motor 321, a drive gear 322, a driven gear 323, and a rotating circular plate 324. The rotating motor 321 is fixedly connected to the side of the mounting plate 31 closest to the ground, and the drive end of the rotating motor 321 is vertically rotatable through the mounting plate 31 via a bearing. The rotating motor 321 is also communicatively connected to the first communication unit 23. The drive gear 322 is coaxially sleeved and fixed to the drive end of the rotating motor 321. The driven gear 323 is rotatably connected to the mounting plate 31, and the driven gear 323 and the drive gear 322 are meshed together. The rotating circular plate 324 is coaxially fixedly connected to the driven gear 323, and a first rotating support member 33 is disposed on the rotating circular plate 324.

[0046] When the drive end of the rotating motor 321 rotates, the drive end of the rotating motor 321 can drive the drive gear 322 to rotate coaxially, the drive gear 322 drives the driven gear 323 to rotate, the driven gear 323 drives the rotating circular plate 324 to rotate, thereby driving the first rotating support member 33 on the rotating table 32 to rotate.

[0047] Reference Figure 3 and Figure 4 The first rotating support 33 includes a support arm 331, a first drive motor 332, and a first rotating arm 333. One end of the support arm 331 is horizontally welded to the rotating circular plate 324, and the other end is rotatably connected to one end of the first rotating arm 333. The first drive motor 332 is fixedly connected to the end of the support arm 331 away from the rotating disk, and the drive end of the first drive motor 332 is fixedly connected to the end of the first rotating arm 333 near the support arm 331. The first drive motor 332 is communicatively connected to the first communication unit 23.

[0048] Reference Figure 3 and Figure 4 The second rotating support 34 includes a second drive motor 341 and a second rotating arm 342. One end of the second rotating arm 342 is rotatably connected to the end of the first rotating arm 333 away from the support arm 331. The second drive motor 341 is fixedly connected to the end of the second rotating arm 342 near the first rotating arm 333, and the drive end of the second drive motor 341 is fixedly connected to the end of the second rotating arm 342 near the first rotating arm 333. The second drive motor 341 is communicatively connected to the first communication unit 23.

[0049] When the rotating motor 321 rotates, it can rotate the support arm 331 to the side facing the mobile carrier 1 away from the mounting plate 31, so that the entire first rotating support 33 is located at the tail of the mobile carrier 1, thereby realizing the storage of the entire first rotating support 33. Alternatively, it can rotate the support arm 331 to the side facing the mobile carrier 1 close to the mounting plate 31, thereby realizing the extension of the entire first rotating support 33.

[0050] When the first drive motor 332 rotates, it drives the first rotating arm 333 to rotate on the horizontal plane, so that the first rotating arm 333 is housed on the support arm 331 or extends from the support arm 331. When the second drive motor 341 rotates, it drives the second rotating arm 342 to rotate on the horizontal plane, so that the second rotating arm 342 is housed on the first rotating arm 333 or extends from the first rotating arm 333.

[0051] It should be understood that the width of the spray curing coverage can be controlled by controlling the positions of the first rotating arm 333 and the second rotating arm 342. The spray curing coverage area is maximized when the first rotating arm 333 and the second rotating arm 342 are aligned in a straight line and both are perpendicular to the mobile vehicle 1. The spray curing coverage area decreases when the first rotating arm 333 and the second rotating arm 342 are aligned in a straight line, and the angle between the first rotating arm 333 and the mobile vehicle 1 is an acute angle; the smaller the acute angle, the smaller the coverage area. The control of the watering position on the concrete pavement is determined by the mobile vehicle 1.

[0052] Reference Figure 3 and Figure 4 The spray assembly 4 includes a water tank 41, a pre-pump solenoid valve 42, a Y-type filter 43, a water pump 44, a post-pump solenoid valve 45, piping fittings 46, and multiple spray heads 47. The water tank 41 is fixedly connected to the mobile vehicle 1, and is located between the front of the mobile vehicle 1 and the mounting plate 31. One end of the Y-type filter 43 is connected to a first water pipe, which is connected to the bottom of the water tank 41. The pre-pump solenoid valve 42 is mounted on the first water pipe. The other end of the Y-type filter 43 is connected to a second water pipe, which is connected to the inlet of the water pump 44. The outlet of the water pump 44 is connected to a third water pipe, on which the post-pump solenoid valve 45 is mounted. The end of the third water pipe furthest from the water pump 44 is connected to piping fittings 46. The water pump 44, the pre-pump solenoid valve 42, and the post-pump solenoid valve 45 are all communicatively connected to the first communication unit 23. Pipe fitting 46 is mounted on support arm 331, first rotating arm 333 and second rotating arm 342, and multiple spray heads 47 are mounted on pipe fitting 46, with the multiple spray heads 47 arranged at equal intervals.

[0053] When it is necessary to spray and cure the concrete pavement, the controller 21 can control the opening and closing of the water pump 44, the pre-pump solenoid valve 42, and the post-pump solenoid valve 45 through the first communication unit 23. After all three are turned on, under the pumping of the water pump 44, the water in the water tank 41 can pass through the pre-pump solenoid valve 42, the Y-type filter 43, the water pump 44, the post-pump solenoid valve 45, and the pipe fittings 46 in sequence, and then be sprayed out by multiple spray heads 47, thereby watering the concrete pavement. When the mobile vehicle 1 moves in a straight line, since the multiple spray heads 47 are set at equal intervals, the sprayed water is more uniform, which can effectively improve the uniformity of water and reduce water waste.

[0054] When overhauling the water pump 44, closing the inlet solenoid valve 42 can prevent water loss from the water tank 41. Installing the outlet solenoid valve 45 and the inlet solenoid valve 42 also facilitates the adjustment of the water pump 44's output and inlet flow rates, reducing the possibility of the pump 44 exceeding its capacity due to excessive water flow per unit time. Furthermore, the Y-type filter 43 filters the water entering the pump 44, reducing the possibility of impurities damaging the pump 44.

[0055] Reference Figure 4 The pipe fitting 46 includes a first corrugated hose 461, a first main water pipe 462, a second corrugated hose 463, a second main water pipe 464, and multiple branch water pipes 465. One end of the first corrugated hose 461 is fixedly connected to the solenoid valve 45 after the pump, and the other end is fixedly connected to one end of the first main water pipe 462. The other end of the first main water pipe 462 is connected to one end of the second corrugated hose 463, and the other end of the second corrugated hose 463 is connected to one end of the second main water pipe 464. The other end of the second main water pipe 464 is closed. The first main water pipe 462 is fixedly connected to the first rotating arm 333 by a bracket, and the second main water pipe 464 is fixedly connected to the second rotating arm 342 by a bracket. Multiple branch water pipes 465 are fixedly connected to the first main water pipe 462 and the second main water pipe 464, and the multiple branch water pipes 465 are arranged at equal intervals. Multiple spray heads 47 are fixedly connected one-to-one to the multiple branch water pipes 465.

[0056] When the drive end of the rotating motor 321 rotates, the position of the support arm 331 changes, and the first corrugated hose 461 can automatically adjust its bending angle according to the change in position of the support arm 331. Similarly, when the drive end of the first drive motor 332 rotates, the position between the support arm 331 and the first rotating arm 333 changes, and the first corrugated hose 461 can automatically adjust its bending angle according to the change in position between the support arm 331 and the first rotating arm 333. When the drive end of the second drive motor 341 rotates, the position between the first rotating arm 333 and the second rotating arm 342 changes, and the second corrugated hose can automatically adjust its bending angle according to the change in position between the first rotating arm 333 and the second rotating arm 342.

[0057] Reference Figure 2 and Figure 3The humidity sensing component 5 includes a geotextile 51, a conditioning circuit module 52, an analog-to-digital converter 53, a second communication unit 54, and multiple humidity sensors 55. The multiple humidity sensors 55 are fixedly connected to the geotextile 51 at equal horizontal and vertical intervals, and all humidity sensors 55 are located on one side of the geotextile 51. When the geotextile 51 is laid on the concrete pavement, the humidity sensors 55 are located on the side of the geotextile 51 closest to the concrete pavement. The cables of the humidity sensors 55 are directly tied with plastic cable ties; after spray curing, the transparent plastic cable ties can be simply cut short with scissors.

[0058] The second communication unit 54 is fixed to one side of the geotextile 51, and the analog-to-digital converter 53 and the conditioning circuit module 52 are built into the second communication unit 54. The second communication unit 54 is connected to the first communication unit 23 and the analog-to-digital converter 53, which are sequentially connected. When the humidity sensor 55 acquires an analog humidity signal from the concrete pavement, the conditioning circuit module 52 conditions the signal, and then the analog-to-digital converter 53 converts the analog signal into a digital signal and sends it to the second communication unit 54. The second communication unit 54 then sends the digital signal to the first communication unit 23, and finally, the controller 21 controls the touch screen 22 to display the humidity. Workers can then determine the humidity level at various points on the concrete pavement based on the humidity sensors 55, allowing them to determine when to water the pavement again.

[0059] Reference Figure 3 The conditioning circuit module 52 includes a sampling circuit unit 521, a voltage conversion unit 522, a low-pass filter unit 523, a drive isolation unit 524, and a limiting protection unit 525. The humidity sensor 55, sampling circuit unit 521, voltage conversion unit 522, low-pass filter unit 523, drive isolation unit 524, limiting protection unit 525, and analog-to-digital converter 53 are connected in sequence. The sampling circuit unit 521 converts the 4-20mA current signal from the humidity sensor 55 into a voltage signal. The voltage conversion unit 522 adjusts the converted voltage signal to meet the input voltage requirements of the second communication unit 54. The low-pass filter unit 523 eliminates power frequency interference and high-frequency interference on the analog channel. The drive isolation unit 524 achieves impedance matching of the input channel. The limiting protection unit 525 keeps the input voltage of the analog-to-digital converter 53 within a specified voltage range, thereby protecting the A / D conversion channel.

[0060] In an optional embodiment of this application, the first corrugated hose 461 and the second corrugated hose 463 can also be replaced with a rotary joint. Alternatively, the first corrugated hose 461, the first main water pipe 462, the second corrugated hose 463, and the second main water pipe 464 can be replaced with a single hose.

[0061] The implementation principle of the intelligent spray curing system for airport concrete pavement construction in this embodiment is as follows: When curing the concrete pavement, workers first lay humidity sensing components 5 on the concrete pavement. Then, workers drive a mobile vehicle 1 to one side of the concrete pavement, and then unfold the first rotating support 33 and the second rotating support 34. While moving the mobile vehicle 1, water is sprayed onto the airport concrete pavement through the spray components 4. After spraying, the concrete pavement can absorb the water to complete hardening and strength increase. At the same time, the water on the concrete pavement continuously decreases, and multiple humidity sensors 55 can continuously monitor the humidity under the geotextile 51 and display the humidity status of various parts of the concrete pavement on the touch screen 22.

[0062] In the above process, instead of using a single water pipe to water the concrete pavement, multiple spray nozzles 47 provide better water uniformity, and workers can determine the humidity of the concrete pavement in real time to determine the next watering time. Therefore, it can reduce water waste while improving the uniformity of curing, thus effectively improving the curing effect of the concrete pavement.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
