Description

Technical Field

[0002] Concrete construction temperature difference detection is an important task during concrete construction, using specific instruments and methods to monitor the temperature differences between the interior and surface of concrete, and between concrete and the environment. Embedded temperature sensors are typically used, tied to the reinforcing steel and connected to a monitoring device. This allows for real-time and accurate acquisition of temperature data from various parts of the concrete, enabling timely detection of abnormal temperature differences, preventing cracks caused by excessive temperature stress, and ensuring the quality and durability of the concrete structure.

[0003] Existing external detection methods involve pre-drilling temperature measurement holes during the drying and molding process of concrete structures. After the concrete has solidified, steel bars are used to insert temperature sensors into the measurement holes. However, the measurement holes are relatively small in size. When the steel bars insert the temperature sensors into the holes, the temperature sensing elements and cables of the temperature sensors are prone to contact with the side walls of the measurement holes, resulting in wear.

[0004] Therefore, the present invention provides a temperature difference detection and early warning device for construction of large-volume concrete for supervision, in order to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing external detection method leaves a temperature measuring hole during the drying and molding process of the concrete structure, and then uses steel bars to introduce the temperature sensor into the temperature measuring hole after the concrete is formed. However, the size and width of the temperature measuring hole are small. When the steel bars introduce the temperature sensor into the hole, the temperature measuring element and cable of the temperature sensor are prone to contact with the side wall of the temperature measuring hole, resulting in wear.

[0006] This utility model provides the following technical solution: a temperature difference detection and early warning device for large-volume concrete construction for supervision, comprising a storage box, a data processing terminal, a detection device, a protection device, and an early warning device. The data processing terminal is installed inside the storage box and is used to summarize and organize the data detected by the detection device. The detection device is installed on the data processing terminal and is used to insert into a pre-set detection hole in the concrete to detect the temperature difference. The protection device is installed on the detection device and is used to protect the detection device when it is inserted into the hole. The early warning device is installed on one side of the data processing terminal and is used to alarm for abnormal temperature data, thereby reminding staff to handle the situation.

[0007] Preferably, the detection device includes a rotating shaft, a rotating disk, a wire clamping groove, a detection cable, and a temperature sensor.

The rotating disk has a wire clamping groove for clamping the detection cable, and the detection cable is wound around the wire clamping groove. A temperature sensor is installed on the detection cable.

[0008] Preferably, the storage box is provided with a limiting hole for the detection cable to pass through, and the storage box is provided with a groove for snapping in the temperature sensor.

[0024] The present invention aims to address the problem that existing external detection methods leave temperature measurement holes during the drying and molding process of concrete structures, and then use steel bars to introduce temperature sensors into the temperature measurement holes after the concrete has been formed. However, the size and width of the temperature measurement holes are relatively small, and when the steel bars introduce the temperature sensor into the holes, the temperature sensing element and cable of the temperature sensor are prone to contact with the side wall of the temperature measurement hole, resulting in wear. In view of this, this disclosure proposes a temperature difference detection and early warning device for large-volume concrete construction for supervision. The rotating shaft drives the rotating disk and wire-clamping groove to rotate, enabling flexible extension and retraction of the detection cable. This allows the temperature sensor to easily penetrate the concrete for accurate temperature difference detection, simplifying operation and facilitating control of the detection depth. The storage box includes holes for the detection cable to pass through and grooves for clamping the temperature sensor, providing an orderly channel for the cable and effectively protecting the temperature sensor, ensuring the stability and accuracy of the detection data. The protection device, through the cooperation of a limiting sleeve, fixing holes, and fixing screws, flexibly adjusts and fixes the position of the protective shell according to the depth of the detection hole, effectively preventing damage to the detection cable and temperature sensor during the detection process. The protective shell consists of a first protective shell and a second protective shell, which can be quickly installed and disassembled through clamping blocks and clamping grooves, improving the device's flexibility. The early warning device includes an alarm and a warning light, which can promptly issue an audible and visual alarm when abnormal internal concrete temperature is detected, facilitating rapid handling by staff and effectively ensuring the quality and safety of large-volume concrete construction, thus improving the overall practicality and reliability of the device.

[0025] like Figures 1 to 4As shown, a temperature difference detection and early warning device for large-volume concrete construction for supervision includes a storage box 1, a data processing terminal 2, a detection device 3, a protection device 4, and an early warning device 5. The storage box 1 houses the data processing terminal 2, which is used to summarize and organize the data detected by the detection device 3. The detection device 3 is mounted on the data processing terminal 2 and is used to insert into a pre-set detection hole in the concrete to detect the temperature difference. The protection device 4 is mounted on the detection device 3 and is used to protect the detection device 3 when it is inserted into the hole. The early warning device 5 is installed on one side of the data processing terminal 2 and is used to alarm for abnormal temperature data, thereby alerting staff to handle the situation.

[0026] The rotating shaft 31 drives the rotating disk 32 and the wire clamping groove 33 to rotate, enabling the flexible extension and retraction of the detection cable 34. This allows the temperature sensor 35 to easily extend into the concrete for accurate temperature difference detection, making operation simple and the detection depth easy to control. The storage box 1 has holes for the detection cable 34 to pass through and grooves 12 for clamping the temperature sensor 35, providing an orderly channel for the cable and effectively protecting the temperature sensor 35, ensuring the stability and accuracy of the detection data. The protection device 4, through the cooperation of the limiting sleeve 41, fixing hole 42 and fixing screw 43, flexibly adjusts according to the depth of the detection hole. The protective housing 44 is adjusted and fixed in position to effectively prevent damage to the detection cable 34 and temperature sensor 35 during the detection process. The protective housing 44 is divided into a first protective housing 441 and a second protective housing 442. It can be quickly installed and disassembled through the snap-fit ​​block 443 and the snap-fit ​​groove 444, which improves the flexibility of the device. The early warning device 5 includes an alarm 51 and a warning light 52, which can promptly issue an audible and visual alarm when abnormal internal temperature of concrete is detected, which facilitates rapid handling by staff and effectively ensures the quality and safety of large-volume concrete construction, thereby improving the practicality and reliability of the entire device.

[0027] like Figures 1 to 4 As shown, the detection device 3 includes a rotating shaft 31, a rotating disk 32, a wire clamping groove 33, a detection cable 34, and a temperature sensor 35. The rotating shaft 31 is installed on one side of the storage box 1 and drives the rotating disk 32 to rotate. The rotating disk 32 is mounted on the rotating shaft 31 and drives the wire clamping groove 33 to rotate. The rotating disk 32 has a wire clamping groove 33 for clamping the detection cable 34. The rotation of the wire clamping groove 33 drives the detection cable 34 to extend out. The detection cable 34 is wound around the wire clamping groove 33 and drives the temperature sensor 35 to extend into the concrete for detection. The temperature sensor 35 is installed on the detection cable 34 and is used to detect the temperature inside the concrete.

[0028] During operation, the staff will first rotate the rotating disk 32. As the rotating disk 32 rotates, the detection cable 34 will be extended out of the cable slot 33. At this time, the staff will install the protection device 4 on the detection cable 34. The detection cable 34 will then be transported into the concrete through the protection device 4. The temperature sensor 35 will then detect the internal temperature and transmit the temperature information to the data processing terminal 2.

[0029] The rotation of the rotating disk 32 and the cable clamping groove 33, driven by the rotating shaft 31, allows for convenient control of the extension and retraction of the detection cable 34. This enables the temperature sensor 35 to flexibly extend into the concrete for temperature detection, simplifying operation and facilitating control of the detection depth. Simultaneously, the protective device 4 effectively protects the detection cable 34 from damage during transport, improving the reliability and lifespan of the device and ensuring the accuracy and stability of the detection data. This provides the supervisory work with an efficient, convenient, and accurate method for temperature difference detection and early warning, guaranteeing the quality and safety of large-volume concrete construction.

[0030] like Figure 1 As shown, the storage box 1 is provided with a limiting hole 11 for the detection cable 34 to pass through, and a groove 12 for engaging the temperature sensor 35. The storage box 1 provides a clear passage for the detection cable 34, ensuring it can enter and exit the storage box 1 in an orderly manner, avoiding cable tangling and other problems, and improving the ease of use of the device. Furthermore, the groove 12 engages the temperature sensor 35, fixing and protecting it, effectively preventing damage from shaking or collision during operation, thus ensuring the accuracy and stability of the temperature monitoring data and improving the overall reliability and monitoring effect of the device.

[0031] like Figures 1 to 4 As shown, the protection device 4 includes a limiting sleeve 41, a fixing hole 42, a fixing screw 43, and a protective shell 44. Two limiting sleeves 41 are installed on the detection cable 34. The limiting sleeves 41 are used to limit the protective shell 44. The limiting sleeves 41 are correspondingly provided with fixing holes 42, which are used to cooperate with the fixing screws 43 to fix the limiting sleeves 41 at a designated position on the cable. The fixing holes 42 are provided with fixing screws 43. The protective shell 44 is fitted on the detection cable 34, and the protective shell 44 is used to protect the detection cable 34 and the temperature sensor 35.

[0032] During operation, the staff fixes the limiting sleeve 41 to the detection cable 34 according to the depth of the reserved detection hole, and aligns the fixing hole 42. At this time, the fixing screw 43 passes through the fixing hole 42 and fixes it to the detection cable 34. Then, the protective shell 44 is fixed to the limiting sleeve 41. By pushing the protective shell 44, the limiting sleeve 41 is moved into the detection hole, thereby realizing the temperature detection inside the concrete.

[0033] With the cooperation of the limiting sleeve 41, fixing hole 42 and fixing screw 43, the position of the protective shell 44 can be flexibly adjusted and fixed according to the depth of the detection hole, ensuring the stability and accuracy of the detection cable 34 and temperature sensor 35 when inserted into the concrete; the protective shell 44 effectively prevents the detection cable 34 and temperature sensor 35 from being damaged by friction, squeezing and other external damage during the detection process, extends the service life of the device, and improves the safety and reliability of the detection process, ensuring the continuity and accuracy of the monitoring data.

[0034] like Figure 4 As shown, the protective shell 44 is divided into a first protective shell 441 and a second protective shell 442. The first protective shell 441 is provided with a snap-fit ​​block 443, and the second protective shell 442 is provided with a snap-fit ​​groove 444 corresponding to the snap-fit ​​block 443. The above design facilitates the installation and disassembly of the protective shell 44, allowing staff to flexibly assemble or replace the protective shell 44 according to actual needs. Secondly, it ensures the stability and sealing of the connection of the protective shell 44, effectively preventing the entry of external impurities such as dust and moisture, further protecting the detection cable 34 and temperature sensor 35 from damage, thereby extending the service life of the device and improving the reliability and safety of the detection work.

[0035] like Figure 1 As shown, the early warning device 5 includes an alarm 51 and a warning light 52. The alarm 51 is installed on the storage box 1, and the warning light 52 is installed above the alarm 51. By installing the alarm 51 on the storage box 1 and setting the warning light 52 above it, a dual warning function of sound and light can be achieved. When an abnormal temperature is detected inside the concrete, the alarm 51 will promptly sound an alarm, and the warning light 52 will flash to attract the attention of the staff, ensuring that the abnormal situation can be quickly detected and dealt with, effectively avoiding concrete structure quality problems caused by abnormal temperature, ensuring the quality and safety of large-volume concrete construction, and improving the reliability and practicality of the entire monitoring and early warning device 5.

[0036] The overall working process is as follows: First, the operator rotates the rotating disk 32. As the disk 32 rotates, the detection cable 34 extends out of the slot 33. Then, according to the depth of the reserved detection hole, the operator fixes the limiting sleeve 41 onto the detection cable 34 and aligns it with the fixing hole 42. The fixing screw 43 passes through the fixing hole 42 and fixes it onto the detection cable 34. The protective shell 44 is then fixed onto the limiting sleeve 41. By pushing the protective shell 44, the limiting sleeve 41 moves into the detection hole. The temperature sensor 35 detects the internal temperature and transmits the temperature information to the data processing terminal 2, completing the temperature difference detection. When an abnormal temperature difference occurs, the alarm 51 sounds an alarm, and the warning light 52 flashes to attract the operator's attention, ensuring that the abnormal situation can be quickly detected and handled, effectively avoiding concrete structure quality problems caused by abnormal temperature, and ensuring the quality and safety of large-volume concrete construction.
