[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 5 As shown in the embodiment of the present invention, a real-time monitoring device for mortar performance under low temperature environment includes an electric push rod 1, a connecting column 2 fixedly connected to the top of the electric push rod 1, an installation block 3 movably inserted inside the connecting column 2, and a base 4 fixedly connected to the end of the installation block 3 away from the connecting column 2. A connecting rod 5 is fixedly connected to the top of the base 4. A horizontal tube 6 is fixedly connected to the surface of the connecting rod 5. A telescopic rod 7 is slidably and sealed inside the horizontal tube 6. The same elastic rope 8 is fixedly connected between the telescopic rod 7 and the inner side wall of the horizontal tube 6. A vertical rod is fixedly connected to the bottom of the telescopic rod 7. A sliding groove is opened on the top of the base 4 to slide with the vertical rod. When the telescopic rod 7 moves, it will drive the vertical rod, so that the bottom end of the vertical rod moves in the sliding groove. The vertical rod can improve the stability of the telescopic rod 7 when it moves and prevent the telescopic rod 7 and all its mechanisms from rotating. The telescopic rod 7 is fixedly connected to a fixed frame 9 at the end away from the horizontal tube 6. The fixed frame 9 and the horizontal tube 6 are fixedly connected to the same air inlet pipe 22. The air inlet pipe 22 is equipped with an air inlet valve and a controller. The fixed frame 9 has a rubber air cylinder 10 fixedly connected to one end on its inner wall. The rubber air cylinder 10 is equipped with an air inlet valve and a controller. The fixed frame 9 has a hollow cavity inside. The hollow cavity has an air pump body inside. The hollow cavity is connected to the rubber air cylinder 10. The inner top wall of the fixing frame 9 is provided with insertion slots 11. Insertion strips 12 are fixedly connected inside the insertion slots 11 by bolts. The same elastic cloth 13 is fixedly connected between a pair of insertion strips 12. A circular plate 44 is placed against one side of the elastic cloth 13. The side of the circular plate 44 is fixedly connected to the rubber air cylinder 10. A movable frame 14 is attached to the other side of the elastic cloth 13. A metal block is fixedly connected to the side of the movable frame 14 near the elastic cloth 13. A magnetic coating is coated on the side of the circular plate 44 near the elastic cloth 13, which is magnetically connected to the metal block. In the initial state, the movable frame 14 and the circular plate 44 are fixed together by the metal block and the magnetic coating. An electric push rod 15 is fixedly connected to the side end of the movable frame 14. A connecting cylinder 16 is fixedly connected to the bottom end of the electric push rod 15. A probe 17 is movably inserted inside the connecting cylinder 16. A spring 18 is fixedly connected between the probe 17 and the connecting cylinder 16. A displacement sensor 19 is provided on the probe 17. Reinforcing grooves 20 are provided on the inner top wall and inner bottom wall of the fixed frame 9. Reinforcing blocks 21 that are compatible with the reinforcing grooves 20 are fixedly connected to the upper and lower sides of the movable frame 14.

[0023] In the existing technology, when existing mortars are used in low-temperature environments, it is difficult for personnel to monitor their hardness in real time. Therefore, it is difficult to accurately grasp the setting and hardening process, hide the risk of early frost damage, and affect construction decisions and schedules, which can easily lead to waste of mortar materials. The present invention is used in the following steps: Step 1: When using, the electric push rod 1 needs to be started so that its telescopic end drives the connecting column 2 and all the mechanisms on it to move up and down together to adjust the height of the probe 17 so that it is directly above the mortar. After moving the probe 17 to a suitable height, start the electric push rod 15 to push the connecting cylinder 16 and all its mechanisms down to fine-tune the position of the probe 17, so that the probe 17 lightly touches the mortar surface. The rebound amplitude of the probe 17 is recorded by the built-in spring 18 and displacement sensor 19. The rebound characteristics are directly related to the hardness of the mortar, thereby realizing automated hardness measurement. Step 2: Start the air pump and open the air inlet valve on the air inlet pipe 22 so that the pump injects gas into the air inlet pipe 22. Finally, the gas will enter the horizontal pipe 6 from the air inlet pipe 22. Then, under the action of the gas thrust, the telescopic rod 7 will pull the elastic rope 8 to move outward of the horizontal pipe 6, thereby causing the probe 17 to move to the left. After the gas action on the telescopic rod 7 is removed, the telescopic rod 7 will be reset under the elastic pull of the elastic rope 8, thereby resetting the probe 17. Then close the air inlet valve on the air inlet pipe 22 and open the air inlet valve on the rubber air cylinder 10 to allow the pump body to inject gas into the rubber air cylinder 10, thereby causing the rubber air cylinder 10 to inflate and expand, and extend in the horizontal direction. This causes the circular plate 44 to push the elastic cloth 13 and the moving frame 14 forward together, thereby causing the probe 17 to move forward. Finally, repeat the steps in step one and use the probe 17 to monitor the hardness of the mortar at different locations in real time. After the pushing force on the elastic cloth 13 is removed, the probe 17 will be pulled back to its original position under its elastic force.

[0024] In summary, when using this invention, the position of the probe 17 is adjusted by adjusting the position of the telescopic rod 7 and the movable frame 14, thereby changing the position of the probe 17 for mortar monitoring. Finally, the probe 17 lightly touches the mortar surface, and the rebound amplitude of the probe 17 is recorded by the built-in spring 18 and displacement sensor 19. The rebound characteristics are directly related to the hardness of the mortar, thus realizing automated hardness measurement. When using this invention, it can monitor the mortar in real time in low-temperature environments, thereby preventing problems such as inaccurate grasp of the setting and hardening process, hidden early frost damage risks, and impact on construction decisions and schedules due to failure to monitor the mortar in a timely manner, and thus reducing the waste of mortar materials.

[0025] like Figure 6 As shown, a round seat 23 is fixedly connected to the bottom end of the electric push rod 1, and a counterweight seat 24 is threadedly connected to the bottom end of the round seat 23. Several round holes are opened at the bottom of the counterweight seat 24, and an electric push rod 25 is fixedly connected to the inner wall of the round holes. A reinforcing cone 26 is fixedly connected to the telescopic end of the electric push rod 25. In use, the round seat 23 needs to be threaded onto the counterweight seat 24. Then, the counterweight seat 24 is placed on the ground, and the electric push rod 25 is activated to push the reinforcing cone 26 down until the entire reinforcing cone 26 is inserted into the ground, thereby improving the stability of the invention on the ground.

[0026] like Figure 2 As shown, the side of the fixing frame 9 is provided with a threaded hole, and a threaded filter plate 27 is threadedly connected inside the threaded hole. An exhaust hole communicating with the hollow cavity is provided on the inner wall of the threaded hole. The threaded filter plate 27 is used to filter the gas entering the hollow cavity to improve the cleanliness of the gas.

[0027] like Figure 2 As shown, an indicator light 28 is fixedly connected to the outside of the threaded filter plate 27. A controller and a blockage sensor are installed inside the threaded filter plate 27. Both the blockage sensor and the indicator light 28 are electrically connected to the controller through wires. When dust and foreign objects block the threaded filter plate 27, the indicator light 28 will light up to remind personnel to unclog the threaded filter plate 27.

[0028] like Figure 5 As shown, a top plate 29 is fixedly connected to the top of the connecting column 2, and a lifting hole is provided at the bottom of the top plate 29. A moving rod 30 is movably inserted into the lifting hole, and a spring 31 is fixedly connected between the moving rod 30 and the lifting hole. A docking hole 32 that matches the moving rod 30 is provided at the top of the base 4. When in use, after the mounting block 3 is inserted into the connecting post 2, the spring 31 will push the moving rod 30 down and insert the bottom end of the moving rod 30 into the mating hole 32, thereby preventing the base 4 from moving away from the connecting post 2. At this time, the spring 31 is in a contracted state.

[0029] like Figure 7 As shown, a mounting bracket 33 is fixedly connected to the top of the fixed frame 9, and a pair of solar panels 34 and a controller are fixedly connected to the side of the mounting bracket 33. The electric push rod 1, the electric push rod 2 15, the air pump body and the displacement sensor 19 are all electrically connected to the solar panels 34. In use, the solar panel 34 converts solar energy into electrical energy to power the electrical components in this invention.

[0030] like Figure 5 As shown, an electric push rod 35 is fixedly connected to the side of the round base 23. An installation cylinder 36 is fixedly connected to the end of the electric push rod 35 away from the round base 23. A reinforcement air pump is installed inside the installation cylinder 36. A suction cup 37 is fixedly connected to the suction end of the reinforcement air pump. If it is inconvenient to install the counterweight 24 and the reinforcing cone 26, the electric push rod 35 needs to be activated so that its telescopic end pushes the suction cup 37 to move, so that the suction cup 37 squeezes the surface of the equipment loaded with mortar. Then, the reinforcing air pump is activated so that it uses the suction cup 37 to apply negative pressure to the equipment to install the present invention on the surface of the equipment.

[0031] Example 2: Figure 7 and Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a motor 38 and a controller are fixedly connected to the side of the mounting bracket 33. A rotating plate 39 is fixedly connected to the output end of the motor 38. A pair of symmetrically distributed rubber scrapers 40 are fixedly connected to the side of the rotating plate 39 near the motor 38. The rubber scrapers 40 are provided with dust inlet holes 41. Both the rotating plate 39 and the rubber scrapers 40 have hollow internal structures. A collection box 42 is fixedly connected to the side of the rotating plate 39 away from the rubber scrapers 40. A dust extraction air pump is provided inside the collection box 42. A sealing cover is threadedly connected to the side of the collection box 42 away from the rotating plate 39. The side of the rubber scrapers 40 away from the rotating plate 39 abuts against the surface of the mounting bracket 33.

[0032] When using this invention, during the use of the solar panel 34, the motor 38 needs to be started periodically by the controller, so that its output end drives the rotating plate 39 and the rubber scraper 40 to rotate together. The rubber scraper 40 is used to scrape and remove dust from the surface of the solar panel 34, thereby improving the cleanliness of the surface of the solar panel 34 and ensuring its effect of converting solar energy into light energy. At the same time, the dust pump is started to suck dust and foreign objects into the collection box 42 through the dust inlet 41 for temporary storage. Finally, the dust and foreign objects inside the collection box 42 are cleaned periodically.

[0033] like Figure 7 As shown, the collection box 42 is equipped with a controller and a detection sensor inside, and an alarm light 43 is fixedly connected to the outside of the collection box 42. The detection sensor and the alarm light 43 are both electrically connected to the controller through wires. Once the collection box 42 has collected a set amount of dust and foreign objects, the alarm light 43 will illuminate, emitting a visual signal to remind personnel, thus facilitating timely cleaning of the dust and foreign objects in the collection box 42.

[0034] like Figure 9 As shown, a method for real-time monitoring of mortar performance under low-temperature conditions, using the aforementioned real-time monitoring device for mortar performance under low-temperature conditions, includes the following steps: S1: Start the electric push rod 15, which will drive the probe 17 to move down and come into contact with the mortar, and detect the displacement of the spring 18 and the probe 17 to detect the hardness of the mortar. S2: During testing, the telescopic rod 7 moves the probe 17 left and right to adjust the left and right position of the probe 17; S3: Then move the moving frame 14 to move the probe 17 back and forth to adjust the position of the probe 17. S4: Finally, repeat the above steps to test the hardness of the mortar.
