Description

Technical Field

[0001] This utility model relates to the field of construction engineering, specifically to an intelligent monitoring and control device for concrete pouring quality, which can be applied to concrete projects of various scales, such as high-rise buildings, bridges, and water conservancy facilities, and is especially suitable for the construction of large-volume concrete and concrete pouring of complex reinforced structures. Background Technology

[0002] In the field of construction engineering, the quality of concrete pouring is crucial to structural safety and durability. Traditional construction methods have the following prominent problems in the vibration and curing stages.

[0003] In terms of vibration, traditional equipment often uses a single vibrator head design, resulting in limited vibration coverage and difficulty in meeting the needs of large-volume concrete construction. Vibrator sticking is prone to occur in densely reinforced areas, leading to uneven concrete density and affecting structural strength. Current vibration quality relies on manual experience for judgment, lacking quantitative testing methods, which easily leads to insufficient or excessive vibration, causing defects such as honeycomb, pitting, or aggregate settling. Furthermore, traditional vibration equipment has high energy consumption and low automation, failing to meet the energy-efficient requirements of modern engineering. Regarding curing, traditional methods control humidity through manual watering or covering with a film, resulting in large humidity fluctuations and localized dryness. Curing and vibration are independent processes, lacking a coordinated control mechanism, making it impossible to dynamically adjust curing parameters based on vibration status, thus affecting the concrete hydration process.

[0004] In existing technologies, vibration and curing equipment operate in isolation, lacking data interaction and intelligent decision-making capabilities. Vibration equipment cannot provide real-time feedback on compaction information, and curing equipment cannot sense the concrete's condition, resulting in delayed control strategies. Therefore, there is an urgent need for an intelligent monitoring and control device for concrete pouring quality to solve these problems. Summary of the Invention

[0021] Example 1: Please refer to Figure 1 This utility model provides an intelligent monitoring and control device for concrete pouring quality, including a vibration device, a curing device, and a control device. The vibration device and the curing device are electrically connected to the control device. The vibration device includes a drive box 101 and a top plate 102. Multiple vibration mechanisms are connected to the bottom of the top plate 102 via multiple rotating seats 107, and these vibration mechanisms are electrically connected to the control device. A motor 104 is connected to the top of the drive box 101 via a first sealing plate 103. A gear 105 is fixedly connected to the output end of the motor 104 via a drive shaft. Multiple toothed rings 106 are provided on the outer side, and a flexible connecting mechanism is provided below the toothed rings 106. The bottom end of the gear 105 is connected to a detection plate 115 via a control shaft 114. The detection plate 115 has two detection holes, and a detection mechanism is provided inside the detection holes. The detection mechanism is electrically connected to the control device. An outer ring 116 is connected to the outer wall of the bottom end of the detection plate 115. Multiple arc-shaped holes are provided on the outer ring 116, and an arc-shaped plate 120 is provided inside the arc-shaped holes. Multiple distance sensors 121 are provided above the arc-shaped plate 120, and the distance sensors 121 are electrically connected to the control device. In this utility model, the gear 105 meshes with the multiple toothed rings 106 on the outer side. The top end of the toothed rings 106 is rotatably connected to the bottom end of the first sealing plate 103 via a rotating ring, and the bottom end of the toothed rings 106 is fixedly connected to the outer wall of the top end of the vibrator 109 via a limiting ring 110.

[0022] Preferably, the vibration mechanism includes a hose 108 and a vibrating rod 109. The bottom end of the top plate 102 is rotatably connected to the top end of the hose 108 via a rotating seat 107, and the bottom end of the hose 108 is fixedly connected to the top end of the vibrating rod 109.

[0023] Preferably, the flexible connection mechanism includes a rubber ring 112 and a sleeve 113. A second sealing plate 111 is fixedly connected to the bottom of the drive box 101. The second sealing plate 111 has multiple compensation holes. The inner sidewall of the compensation hole is rotatably connected to the outer sidewall of the rubber ring 112. The bottom of the rubber ring 112 is fixedly connected to the outer sidewall of the vibrator 109 through the sleeve 113.

[0024] Preferably, the detection mechanism includes a pressure hopper 117 and a pressure sensor 119. The outer wall of the bottom end of the pressure hopper 117 is fixedly connected to the inner wall of the detection hole on the detection plate 115, and the top end of the pressure hopper 117 is fixedly connected to the detection end of the pressure sensor 119 through a pipe 118.

[0025] In this invention, the vibrating device employs multi-head synchronous drive and intelligent detection technology. During operation, the motor 104 drives the gear 105 to rotate, which in turn drives multiple vibrating rods 109 to rotate synchronously via the meshing gear ring 106. Each vibrating rod 109 is connected to the top plate 102 via a flexible hose 108, allowing for free polarization within a 360° range. The gear ring 106 is rigidly connected to the vibrating rod 109 via a limiting ring 110, ensuring the synergistic effect of rotation and polarization. The flexible connection mechanism composed of the rubber ring 112 and the sleeve 113 allows the vibrating rod 109 to move adaptively within a vertical range of ±5cm. When the vibrating rod contacts the reinforcing steel or aggregate, the sleeve 113 absorbs the impact force through elastic deformation, and the rubber ring 112 rotates within the compensation hole, avoiding rigid jamming. The detection plate 115 rotates synchronously with the gear 105, and the arc-shaped plate 120 on the outer ring 116 contacts the concrete surface. When the concrete is not compacted to the required standard, the pressure from the grouting pushes the arc-shaped plate 120 upwards, triggering a signal change in the distance sensor 121. Simultaneously, the pressure hopper 117 detects changes in the internal air pressure of the concrete, transmitting this information through pipe 118 to the air pressure sensor 119, thus comprehensively judging the vibration quality. The detection mechanism collects real-time data on vibration frequency (10-50Hz), pressure (0-10MPa), and concrete surface displacement (±3mm), transmitting this data to the control device via an RS485 bus. A fuzzy PID algorithm dynamically adjusts the vibration time (±5%) and amplitude (±0.5mm) to ensure a vibration uniformity coefficient ≥0.92. In the vibration device, four vibrating rods 109 are arranged in a 90° circle, covering an area with a diameter of 1.2m, achieving a vibration efficiency of 1.2㎡ / min. The distance sensor 121 detects surface displacement, and the air pressure sensor 119 monitors internal air pressure, comprehensively judging the compaction degree. The fuzzy PID algorithm has a response time of ≤200ms and a vibration parameter adjustment step of 1Hz / 0.5mm, improving accuracy by 80% compared to traditional equipment. Gear 105 and gear ring 106 mesh to achieve a vibration uniformity coefficient of 0.92. The combination of rubber ring 112 and sleeve 113 allows the vibrator to move freely within a ±5cm range while maintaining vibration stability, solving the problem of jamming in densely reinforced areas. Distance sensor 121 and air pressure sensor 119 work together to quantitatively determine concrete density, with a false judgment rate of ≤2%.

[0026] In this invention, the curing device includes a high-pressure atomizing nozzle and a temperature and humidity sensor, both electrically connected to a control device. Preferably, the temperature and humidity sensor is positioned 10-15 cm above the concrete surface to directly monitor changes in surface humidity. Preferably, the temperature and humidity sensor is fixed by an adjustable bracket with an adjustment angle of ±45° to prevent direct impact of the spray on the sensor. The curing device adopts a modular integrated design, achieving efficient collaboration through mechanical and electrical interfaces. The nozzle body of the high-pressure atomizing nozzle is made of 316L stainless steel, with an internal three-stage spiral guide channel. Water flows through the guide channel and rotates rapidly, forming ultra-fine droplets ≤50μm. The core component, a ceramic valve core, works in conjunction with a spring pre-tightening mechanism to ensure stable operation under 1.5-3MPa water pressure, with a wear-resistant life of 10,000 hours. The nozzle is connected to the bracket via a quick-connect flange, allowing for single nozzle replacement within 3 minutes. The temperature and humidity sensor uses an SHT31-D digital sensor, integrating dual-parameter temperature and humidity detection. The temperature and humidity sensor is fixed to the concrete surface 10-15cm above it using an adjustable aluminum alloy bracket. The bracket design includes a spherical hinge joint, supporting ±45° tilt adjustment to ensure the probe is aligned with the concrete surface and avoids direct spray areas. The sensor has a built-in splash guard and makes direct contact with the concrete surface via thermally conductive silicone, with a response time of ≤8 seconds. The control unit's enclosure is designed with IP67 protection and integrates an STM32H743 microprocessor, a 4G communication module, and quick-release terminals. During operation, the temperature and humidity sensor collects temperature and humidity data from the concrete surface at a frequency of 10Hz and transmits it to the control box via shielded twisted-pair cable. The sensor uses a triangular array, and the data is weighted and averaged to eliminate local interference. When the vibration device detects a compaction deviation >5%, the system automatically increases the humidity threshold by 5% to compensate for moisture loss caused by vibration. When the ambient temperature is >35℃, the spray cooling mode is activated, and the vibration frequency is reduced simultaneously. The curing device employs spiral-guided atomization technology, achieving a spray uniformity coefficient of 0.95 and maintaining stable concrete surface humidity at 70-80%RH (±2%RH), reducing fluctuations by 80% compared to traditional curing methods. It operates across a full temperature range of -20℃ to 60℃, with battery capacity retention exceeding 90% even in low-temperature environments. Through structural innovation and intelligent algorithms, the device provides a high-precision, high-reliability solution for concrete curing, suitable for large-volume concrete and complex reinforced structures, offering significant economic benefits and engineering application value. Compared to existing technologies, it reduces crack incidence by 25%, narrows the strength standard deviation to ±3MPa, and lowers the peak center temperature of large-volume concrete by 13℃, effectively suppressing shrinkage cracks.

[0027] In this invention, the control device includes a central processing unit, a wireless communication module, and a human-machine interface module. The human-machine interface module is electrically connected to the central processing unit via the wireless communication module. The central processing unit has a built-in fuzzy PID controller and a preset vibration strategy library. The wireless communication module supports dual communication modes of 4G LTE and CAN bus. The human-machine interface module includes a 7-inch touchscreen, status indicator lights, and an emergency stop button for easier operation. Preferably, the control device has a built-in fuzzy PID controller, which is electrically connected to the high-pressure atomizing nozzle and temperature and humidity sensors. The control device contains multiple fuzzy rules, uses the centroid method for defuzzification, outputs a PWM signal, supports preset curing strategies, and calculates the spray volume adjustment based on humidity deviation and the rate of change of deviation. The control device dynamically optimizes the spray volume and vibration strategy through multi-source data fusion and remote monitoring, supporting curing modes for various preset concrete grades.
