An insertion-type temperature sensor for measuring low-temperature concrete Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an insertion-type temperature sensor for measuring low-temperature concrete. Background Technology

[0002] Concrete is one of the most common building materials in construction. Concrete needs to be dried and shaped naturally to ensure its hardness. In order to ensure that the concrete meets the standards during the drying process, a temperature sensor is needed to measure its interior to detect whether there is still water seepage inside that causes the temperature to be too low, thus failing to meet the standards.

[0003] However, most temperature sensors are small in size, and when faced with large-area concrete measurement work, they are often unable to penetrate the concrete surface for detection, or the penetration thickness is limited, resulting in inaccurate data. Therefore, we propose an insertion-type temperature sensor for measuring low-temperature concrete. Summary of the Invention

[0004] The purpose of this invention is to provide an insertion-type temperature sensor for measuring low-temperature concrete, which solves the technical problems of most temperature sensors being small in size, unable to penetrate the concrete surface for testing when dealing with large-area concrete measurements, or having limited penetration thickness, resulting in inaccurate data. The invention aims to provide a temperature sensor with better puncture resistance, enabling it to measure concrete of different thicknesses and increasing the accuracy of the measurement data.

A temperature measuring head 15 is installed at the end of the connecting wire 14 away from the temperature sensor body 13. A protective shell 16 is installed on the surface of the temperature measuring head 15.

[0026] Example 2

[0027] As shown in Figures 1 to 4, the display screen of the control panel 2 is a touch screen. The control panel 2 integrates temperature data display and operation command input functions. The control panel 2 is electrically connected to the lead screw 7, motor 9, and temperature sensor body 13 for convenient control of the temperature sensor. The control panel 2 is fixed to the movable housing 1 by bolts. The hub of the movable wheel 3 is equipped with a brake structure to increase the stability of the temperature sensor when it stops. The surface of the movable wheel 3 is covered with a rubber layer, and the wheel diameter of the movable wheel 3 is greater than or equal to 80mm. The closed door 4 is connected to the movable housing 1 by a hinge. A handle is welded to the top of the closed door 4 for easy opening and maintenance of the temperature sensor. The mounting plate 5 is fixed to the movable housing 1 by bolts. The slide groove 6 is symmetrically opened at the top and bottom. The lead screw 7 adopts a trapezoidal thread structure to improve the load capacity. The surface of the lead screw 7 is chrome-plated for rust prevention. The connecting plate 8 is embedded with a self-lubricating copper sleeve to achieve low-friction transmission of the lead screw 7. The motor 9 passes through the slide groove 6 and is connected to the connecting plate 8 by bolts. The motor 9 can slide within the slide groove 6. The sleeve 10 is fixed to the connecting plate 8 by bolts. The sleeve 10 can slide within the slide groove 6. Two sleeves 10 are symmetrically installed. The telescopic rod 11 can slide within the sleeve 10. The minimum extension length of the telescopic rod 11 is greater than or equal to 1.2m.

The protective shell 16 is fixed to the telescopic rod 11 by screws.

[0028] In summary, when using an insertion-type temperature sensor for measuring low-temperature concrete, the movable housing 1 is moved above the concrete via the moving wheels 3. Then, the motor 9 is started, causing the telescopic rod 11 to descend. The vertical cone 12 breaks through the concrete surface, allowing the temperature measuring head 15 to enter the concrete. The temperature measured by the temperature measuring head 15 is transmitted to the temperature sensor body 13, and finally to the control panel 2. After measurement, the telescopic rod 11 can be moved via the lead screw 7 to adjust its lateral position, allowing it to measure the concrete temperature at different locations and obtain more data. This insertion-type temperature sensor has better puncture resistance, enabling it to measure concrete of different thicknesses and increasing the accuracy of the measurement data.
