Description

Technical Field

[0001] This utility model relates to a temperature measuring instrument for large-volume concrete. Background Technology

[0002] During the hardening process of large-volume concrete, the cement hydration reaction releases a large amount of heat. Due to its large volume, the heat is not easily dissipated, causing the internal temperature to rise sharply, while the surface dissipates heat more quickly, thus creating a huge temperature difference between the inside and outside. This temperature difference causes the internal concrete to expand and the external concrete to shrink, and the mutual restraint generates tensile stress. When the tensile stress exceeds the tensile strength of the concrete, harmful cracks will occur, damaging the integrity, waterproofness and durability of the structure.

[0003] Currently, the main method for detecting the temperature of large-volume concrete is to use pre-embedded temperature sensors. Existing temperature sensors are fixed on the reinforcing steel cage. When detecting the temperature, the detection position of the temperature sensor is determined by the size of the reinforcing steel cage and the available installation location. The detection position of the temperature sensor cannot be adjusted and can only be roughly installed according to the available installation location on the reinforcing steel cage, which leads to inaccurate detection data. Summary of the Invention

The limiting end of the main shaft 31 is located in the sliding groove 11 after passing through the limiting channel. A threaded portion is provided on the main shaft 31 near the limiting end. A threaded hole 211 is provided through the sliding block 21 to form a threaded engagement with the threaded portion. The limiting end of the main shaft 31, through the threaded engagement with the threaded hole 211, is pressed against the groove wall of the sliding groove 11 after passing through the sliding block 21. An extension direction along the sliding groove 11 is fixed on the groove wall of the sliding groove 11. The elastic rubber pad 5 extends outward, and the limiting end of the main shaft 31 acts on the elastic rubber pad 5; the pressure block 32 is fixedly installed on the driving end of the main shaft 31. After the pressure block 32 is pressed against the groove wall of the sliding through groove 11 by the limiting end of the main shaft 31, it is pressed against the mounting body 1.

One end of the temperature probe 42 is fixedly mounted on the mounting block 41, and the other end of the temperature probe 42 faces outward. The mounting base 2 has a mounting groove 23. The mounting block 41 is detachably mounted in the mounting groove 23 via a snap-fit ​​assembly 6. A sliding groove communicating with the outer wall of the mounting groove 23 is located on the side wall of the sliding groove. An extension groove 22 coaxially arranged with the sliding groove is located on the inner wall of the sliding groove. The snap-fit ​​assembly 6 includes a rod 61, a stop 62, an extension block 63, and a return spring 64. The rod 61 is slidably disposed in the sliding groove.

The reset spring 64 is disposed in the extension groove 22. One end of the reset spring 64 acts on the end of the extension groove 22 away from the mounting groove 23, and the other end of the reset spring 64 acts on the extension block 63. The end of the insertion rod 61 facing the mounting groove 23 slides into the mounting groove 23 under the action of the reset spring 64. The mounting block 41 is provided with a socket 411 for the insertion rod 61 to be inserted and form a plug-in fit. The mounting block 41 is installed in the mounting groove 23 by the action of the reset spring 64 on the insertion rod 61 and the plug-in fit between the insertion rod 61 and the socket 411. The temperature probe 42 can be added or removed as needed by the detachable installation of the mounting block 41 in the mounting groove 23, so as to avoid waste of resources.

[0028] The stop 62 prevents the end of the insert rod 61 away from the mounting slot 23 from entering the sliding slot.

[0029] The end of the insertion rod 61 facing the mounting groove 23 is provided with a guide slope 611 for guiding the insertion rod 61 into the insertion hole 411 after contacting the mounting block 41. The lower end of the guide slope 611 extends toward the bottom of the mounting groove 23, and the upper end of the guide slope 611 extends toward the opening of the mounting groove 23.

[0030] The mounting body 1 is provided with a scale 13 extending along the extension direction of the mounting body 1, and the sliding block 21 is provided with an alignment mark 212 for aligning the scale of the scale 13; the scale 13 and the alignment mark 212 can determine the position of the mounting seat 2 and the sliding block 21 on the sliding through groove 11, and can make precise adjustments to the position of the mounting seat 2 as needed.

[0031] There are three mounting bases 2, which are respectively set at the upper, middle and lower ends of the mounting body 1. The temperature probe 42 is a Bluetooth portable temperature acquisition device, and an external collector is also provided to receive the data detected by the temperature probe 42. Each temperature probe 42 can face the collector to transmit the detected temperature result. At the same time, it can collect the temperature of the surface, middle and bottom of the large-volume concrete at fixed time and can automatically calculate the temperature difference. The software automatically generates a report, and an alarm is automatically triggered when the temperature difference is greater than 25°C. The temperature probe 42 transmits data to the collector to realize the temperature measurement. How the temperature probe 42 transmits data and how it displays it on the collector are existing technologies and will not be described in detail here.

[0032] The working principle of this utility model is as follows: The mounting block 41 is inserted into the mounting groove 23. Under the guidance of the guide slope 611, the mounting block 41 pushes the insertion rod 61. During the movement, the insertion rod 61 drives the extension block 63 to squeeze the return spring 64. When the end of the insertion rod 61 facing the mounting groove 23 reaches the position of the insertion hole 411, the insertion rod 61 enters the insertion hole 411 under the elastic force of the return spring 64 on the extension block 63, thus fixing the mounting block 41 in the mounting groove 23.

[0033] The position of the mounting base 2 is determined by aligning the alignment mark 212 with the scale 13. The rotating pressure block 32 drives the main shaft 31 to rotate. The main shaft 31 moves toward the elastic rubber pad 5 with the cooperation of the threaded part and the screw hole 211. After the limiting end of the main shaft 31 completely squeezes the elastic rubber pad 5, the pressure block 32 acts on the mounting body 1. At this time, the mounting base 2 is fixed on the mounting body 1.
