Description

Technical Field

[0001] This utility model relates to the field of bridge maintenance technology, specifically to a steam curing humidity detection device for bridge maintenance. Background Technology

[0002] In the construction of precast components or the later-stage curing of cast-in-place concrete in bridge engineering, steam curing is a process to improve the early strength of concrete and ensure project quality. During this process, the humidity within the curing shed is a key control parameter, and its uniformity and stability directly affect the adequacy of the concrete hydration reaction.

[0003] Existing bridge maintenance equipment typically involves large spaces and relies on only a few independent, fixed humidity sensors. The data collected is insufficiently representative and cannot quickly and comprehensively reflect the true humidity levels within the entire maintenance space. Therefore, a humidity detection device for steam curing in bridge maintenance is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a humidity detection device for steam curing in bridge maintenance. By setting a slider assembly with a humidity sensor that can be adjusted along the length of the chute, the device can realize synchronous and multi-point detection of humidity in different areas inside the steam curing chamber, thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A humidity detection device for steam curing in bridge maintenance includes a steam curing chamber, wherein detection components for detecting the humidity of the steam curing environment are symmetrically installed on the inner walls of opposite sides of the steam curing chamber.

[0007] The detection component includes a trough formed on the inner side wall of the steam curing chamber. Several sets of partitions are evenly spaced along the length of the trough. A slider is installed between every two sets of adjacent partitions. The sliders are slidably embedded in the trough and their positions can be adjusted along the length of the trough. A humidity sensor for real-time humidity data acquisition is installed on the side wall of each set of sliders away from the trough.

[0008] Preferably, a lead screw is rotatably installed inside the slide groove, and the lead screw passes through and is movably inserted into the middle of several sets of corresponding partitions.

[0009] Preferably, each set of sliders has a matching threaded hole in the middle of the lead screw, and several sets of sliders are threadedly connected to the middle of the lead screw through the threaded hole.

[0010] Preferably, a motor for driving a lead screw is embedded in the outer wall of the steam curing chamber, and the output end of the motor is keyed to one end of the lead screw.

[0011] Preferably, each set of sliders has symmetrical mounting grooves on its upper and lower side walls, and a roller is rotatably mounted inside each set of mounting grooves. The upper and lower side walls of the sliding grooves have movable grooves for the rollers to roll and adapt.

[0012] Preferably, each set of sliders has a detachable protective cover installed on its sidewall. Each set of protective covers is placed outside the corresponding humidity sensor, and the outer wall of each set of protective covers has several sets of air holes for gas flow.

[0013] Preferably, each set of sliders has an annular groove on its side wall, and two sets of locking blocks are symmetrically installed on the outer wall of the opening end of each set of protective covers, with the two sets of locking blocks correspondingly engaging inside the annular groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides: a humidity detection device for steam curing in bridge maintenance, such as... Figures 1-4 As shown, the system includes a steam curing chamber 1, with symmetrically installed detection components 2 on opposite inner walls of the chamber 1 for detecting the humidity of the steam curing environment. The steam curing chamber 1 provides a mounting base and enclosed steam curing space for all internal components. The detection components 2 are symmetrically installed on opposite inner walls of the steam curing chamber 1 to detect the humidity of the internal environment of the steam curing chamber.

[0023] The detection component 2 includes a groove 21 formed in the inner wall of the steam curing chamber 1. Several sets of partitions 22 are evenly spaced along the length of the groove 21. A slider 23 is installed between every two adjacent sets of partitions 22. All sets of sliders 23 are slidably embedded in the groove 21 and their positions can be adjusted along the length of the groove 21. A humidity sensor 24 for real-time humidity data acquisition is installed on the side wall of each set of sliders 23 away from the groove 21. The groove 21, formed in the inner wall of the steam curing chamber 1, provides a sliding track for the sliders 23, limiting their movement to the length of the groove 21. The partitions 22 separate the sets of sliders 23 into different areas, preventing collisions and ensuring accuracy during detection. The sliders 23, slidably embedded in the groove 21, move synchronously with the humidity sensor 24, enabling flexible adjustment of the detection point. The humidity sensor 24 directly acquires humidity data, capturing the humidity of the steam curing environment at its location in real time. Based on the different needs of the curing areas inside the steam curing chamber 1, the position of the slider 23 within the slide groove 21 is adjusted via the drive structure. The slider 23 then moves the humidity sensor 24 to the designated detection point. At this time, multiple sets of humidity sensors 24 work synchronously, collecting humidity data from their respective points in real time. The combination of multiple sets of data can comprehensively reflect the humidity status inside the steam curing chamber 1, solving the problem of insufficient representativeness of data detected by traditional fixed, few sensors.

[0024] The humidity sensor 24 can be selected from models with a measurement range of 0-100%RH, an accuracy of ±2%RH, an operating temperature of -40℃ to 125℃, and a response time of ≤8 seconds. The -40℃ to 125℃ operating temperature range can handle temperature fluctuations during steam curing, preventing sensor damage due to high temperatures; the high accuracy of ±2%RH ensures accurate and reliable humidity data collection, providing precise data for humidity control in bridge maintenance. The fast response time of ≤8 seconds allows for real-time capture of humidity changes within the steam curing chamber 1, enabling multi-point detection in conjunction with the movement of the sensor driven by the slider 23.

[0025] Preferably, a lead screw 25 is rotatably mounted inside the slide groove 21, and the lead screw 25 passes through and is movably inserted into the middle of several sets of corresponding partitions 22. The rotation of the lead screw 25 inside the slide groove 21 can drive the slider 23 to move, and the design of passing through the partitions 22 can ensure the coaxiality of the lead screw 25 when rotating in the slide groove 21, avoiding the slider 23 from getting stuck due to misalignment.

[0026] Furthermore, each set of sliders 23 has a matching threaded hole 231 in the middle corresponding to the lead screw 25. Several sets of sliders 23 are threadedly connected to the middle of the lead screw 25 through the threaded hole 231. The threaded connection converts the rotational motion of the lead screw 25 into the linear motion of the slider 23 along the axial direction of the lead screw 25, achieving precise adjustment of the slider 23's position. Moreover, the threaded structure has self-locking properties, automatically fixing the slider 23 after it moves to the designated position without the need for additional limiting components.

[0027] Furthermore, a motor 26, which drives the lead screw 25, is embedded in the outer wall of the steam curing chamber 1. The output end of the motor 26 is keyed to one end of the lead screw 25. The motor 26 drives the lead screw 25 to rotate and outputs stable rotational power after being powered on. Through the keyed connection, the power of the motor 26 can be efficiently transmitted to the lead screw 25, causing the lead screw 25 to rotate at a uniform speed within the slide groove 21, ensuring the smooth movement of the slider 23. When it is necessary to adjust the detection position of the humidity sensor 24, the motor 26 on the outer wall of the steam curing chamber 1 is started, and the motor 26 drives the lead screw 25 to rotate within the slide groove 21. Since the slider 23 is threadedly connected to the lead screw 25 through the threaded hole 231, and the slider 23 is embedded in the slide groove 21 and cannot rotate synchronously with the lead screw 25, the rotational motion of the lead screw 25 is converted into linear motion of the slider 23 along the length of the slide groove 21, thereby driving the humidity sensor 24 to the target detection point, realizing automated detection point adjustment, and improving the ease of operation and detection efficiency of the device.

[0028] Motor 26 can be a stepper motor with a step angle of 1.8°, a rated torque of 0.4 N·m, and a reduction ratio of 5:1 (optional). The 1.8° step angle combined with the optional 5:1 reduction ratio enables minute rotation of the lead screw 25, meeting the fine adjustment requirements of the humidity sensor 24 at different detection points within the slide 21. The rated torque of 0.4 N·m is sufficient to overcome the frictional resistance between the slider 23 and the slide 21, and between the lead screw 25 and the threaded hole 231.

[0029] It is worth noting that each set of sliders 23 has symmetrical mounting grooves 232 on its upper and lower side walls, and a roller 233 is rotatably mounted inside each mounting groove 232. The upper and lower side walls of the slide groove 21 have movable grooves 27 for the rollers 233 to roll and adapt. The mounting grooves 232 provide mounting space for the rollers 233 and also limit their movement. The rollers 233 convert the sliding friction between the sliders 23 and the slide groove 21 into rolling friction, preventing wear of the sliders 23 due to excessive friction and extending the service life of the components. The movable grooves 27 limit the rolling trajectory of the rollers 233, further ensuring that the sliders 23 move along the length of the slide groove 21, preventing vertical displacement of the sliders 23 during movement, and ensuring the stability of the sliders 23 when moving the humidity sensor 24.

[0030] Specifically, each set of sliders 23 has a detachable protective cover 3 installed on its side wall. Each protective cover 3 covers the outside of the corresponding humidity sensor 24, and the outer wall of each protective cover 3 has several sets of vent holes 4 for gas flow. The protective cover 3 effectively prevents debris generated inside the steam curing chamber 1 from directly contacting the humidity sensor 24, avoiding damage to the humidity sensor 24 due to debris and extending its service life. The vent holes 4 allow humid air inside the steam curing chamber 1 to smoothly enter the protective cover 3 and contact the humidity sensor 24, ensuring that the humidity sensor 24 can normally collect humidity data of the surrounding environment and preventing data distortion caused by the obstruction of the protective cover 3.

[0031] More specifically, each set of sliders 23 has an annular groove 5 on its side wall, and two sets of locking blocks 6 are symmetrically installed on the outer wall of the opening end of each set of protective covers 3. The two sets of locking blocks 6 are engaged with each other inside the annular groove 5. The annular groove 5 and the locking blocks 6 cooperate with each other to achieve a detachable connection between the protective cover 3 and the slider 23. During installation, align the locking block 6 at the opening end of the protective cover 3 with the annular groove 5 of the slider 23, push it in and rotate the protective cover 3 to make the locking block 6 engage inside the annular groove 5, thus completing the fixation; during disassembly, the protective cover 3 can be removed by reversing the operation, which facilitates the maintenance of the humidity sensor 24.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
