Description

Technical Field

[0001] This utility model relates to the field of cement substrate technology, and in particular to a cement substrate temperature and humidity detection device. Background Technology

[0002] Cement: A powdered hydraulic inorganic binder. When mixed with water, it forms a paste that hardens in air or water, and can firmly bind materials such as sand and stone together. Early mixtures of lime and volcanic ash were very similar to modern lime-volcanic ash cement. Concrete made with this binder not only had high strength after hardening but also resisted erosion from fresh or salt water.

[0003] Cement-based materials refer to composite materials made by combining silicate cement as the matrix, alkali-resistant glass fiber, general-purpose synthetic fiber, various ceramic fibers, high-performance fibers such as carbon and aramid, metal wire, and natural plant and mineral fibers as reinforcements, and adding fillers, chemical additives, and water through a composite process. Concrete and mortar are the most common cement-based materials.

[0004] The temperature and humidity inside precast concrete materials are constantly changing, and traditional surface temperature and humidity detectors cannot detect the temperature and humidity inside cement concrete after initial setting. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems and deficiencies by proposing a temperature and humidity detection device for cement substrates: an air pump draws in outside air and delivers it to the insertion slot through an air inlet pipe and a connecting hole. After the gas comes into contact with the concrete inside, it enters another insertion slot through another air outlet. A humidity sensor detects the humidity of the gas, making it convenient to detect humidity and easy to use.

The counterweight 3 is placed on the top of the protective cover 1, and the counterweight 3 presses the protective cover 1 against the outer wall of the concrete, reducing the entry or exit of gas from between the protective cover 1 and the concrete, making it easy to use, easy to detect, and improving the accuracy of detection.

[0023] The detection structure 2 includes a mounting plate 7, an insertion rod 8 mounted on the outer wall of one end of the mounting plate 7, insertion grooves 9 at both ends of the top outer wall of the insertion rod 8, a threaded groove 10 at the insertion groove 9 on the top outer wall of the insertion rod 8, a connecting groove 11 at the bottom of the outer wall of the insertion rod 8, an air outlet 12 at both ends of the connecting groove 11 on the insertion rod 8, temperature sensors 19 mounted on the outer walls of both sides of the insertion rod 8, and an air pump 17 mounted on one end of the top outer wall of the mounting plate 7.

[0024] The insertion rod 8 is provided with a connection hole 16 at the top of an extension groove 9, and the output end of the air pump 17 is connected to one end of the connection hole 16.

[0025] A threaded block 14 is threadedly connected to the threaded groove 10, and a sliding tube 15 is welded to the bottom outer wall of the threaded block 14. The outer wall of the sliding tube 15 is slidably connected to the inner wall of the insertion groove 9. Rotating the threaded block 14 in the threaded groove 10 removes the sliding tube 15 from the insertion groove 9. A threaded block 14 is threadedly connected to the threaded groove 10 at the connection hole 16. Cement is placed into the insertion groove 9 through the sliding tube 15.

[0026] The input end of the air pump 17 is connected to the air inlet pipe 18, and the other end of the air inlet pipe 18 is fixed in the protective cover 1. The gas rises into the protective cover 1, and the humidity sensor 20 detects the humidity of the gas. This facilitates humidity detection and ease of use. Excess gas is discharged from the exhaust valve 5.

[0027] One end of the air outlet 12 is connected to the extension groove 9, and the insertion rod 8 is equipped with a mudguard ring 13 at the connecting groove 11.

[0029] Working principle: During use, apply a release agent to the outer wall of the insertion rod 8, install the insertion rod 8 in the mounting plate 7, and cover the precast concrete surface with the protective cover 1. At this time, the insertion rod 8 is inserted into the concrete. The temperature sensor 19 on the surface of the insertion rod 8 detects the temperature in the concrete, which is convenient for detecting the temperature at different depths. After the concrete is relatively dry, remove the protective cover 1 from the concrete. Rotate the threaded block 14 in the threaded groove 10 to remove the sliding tube 15 from the insertion groove 9. Thread one threaded block 14 into the threaded groove 10 at the connection hole 16. After starting the air pump 17, draw in outside air and deliver it to the insertion groove 9 through the air inlet pipe 18 and the connection hole 16. Then, the gas is discharged from the air outlet 12 at the connecting groove 11 at the bottom of the insertion rod 8. After the gas comes into contact with the concrete inside, it enters another insertion groove 9 through another air outlet 12. Then, the gas rises into the interior of the protective cover 1. The humidity sensor 20 detects the humidity of the gas, which is convenient for humidity detection and use. Excess gas is discharged from the exhaust valve 5.
