[0015] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a stress detection device for a concrete gravity dam, achieving the following beneficial effects: (1) In order to solve the problem that the currently widely used ultrasonic detection technology mostly adopts a fixed-point detection method when conducting stress detection on concrete gravity dams, that is, a number of detection points are preset on the dam body and detected one by one, which cannot comprehensively and continuously reflect the distribution of dam body stress, the present invention provides a dry type dam body surface flattening mechanism, which first flattens and cleans the dam body surface, and then applies a colloidal coupling agent, thereby ensuring a uniform and close contact layer between the ultrasonic detection head and the dam body, thereby improving the accuracy of stress detection.

[0016] (2) Through the dry type dam surface flattening mechanism, the spiral blades flatten the protruding uneven parts of the dam surface by rotating, which eliminates the ultrasonic reflection error that may be caused by the uneven surface, thereby improving the accuracy of subsequent stress detection.

[0017] (3) Through the dry type dam surface leveling mechanism, the cleaning brush cleans the flattened debris, and the hot air flow generated by the hot air blower further removes the surface dust and tiny particles, ensuring a clean and close contact layer between the ultrasonic detection head and the dam surface, reducing signal attenuation and interference.

[0018] (4) Through the dry-type dam surface smoothing mechanism, the spiral blades work close to the dam surface but without touching it, avoiding damage to the dam or equipment wear that may be caused by direct contact in traditional methods. The combined use of spiral blades and cleaning brushes can cope with dam surfaces of different roughness and cleanliness, enhancing the adaptability and flexibility of the equipment.

[0019] (5) The use of a hot air blower can not only clean the surface, but also to a certain extent cope with adverse environmental conditions such as humidity or low temperature, ensuring the smooth progress of the inspection work.

[0020] (6) The coupling agent is evenly applied to the surface of the dam through a mobile bonding ultrasonic stress detection mechanism. This continuous and uniform application method ensures a close fit between the coupling agent and the surface of the dam, improving the coupling effect of ultrasonic detection.

[0021] (7) Through the mobile bonding type ultrasonic stress detection mechanism, the colloidal coupling agent is used as the medium for ultrasonic propagation. Its uniformity and tightness directly affect the accuracy of the detection results. By precisely controlling the coating thickness and uniformity of the coupling agent, ideal detection conditions are provided for ultrasonic detection. The cleaned dam surface and the evenly coated coupling agent layer reduce the scattering and attenuation during ultrasonic propagation, reducing the impact of external interference on the detection results.

[0022] (8) The colloidal coupling agent can also fill the tiny unevenness on the dam surface to a certain extent, thereby improving the accuracy of detection.

[0023] (9) The colloidal coupling agent can fill the tiny gap between the ultrasonic probe and the surface of the dam body, eliminating the influence of the air gap on the propagation of ultrasonic waves. Air is a poor conductor of ultrasonic waves, which will cause the reflection and attenuation of sound waves, thereby reducing the accuracy of detection. The use of coupling agent ensures that the sound waves can be smoothly transmitted into the interior of the dam body, improving the accuracy of detection. The acoustic impedance of the colloidal coupling agent is similar to that of the dam body material, which can reduce the reflection of ultrasonic waves at the interface between the probe and the dam body, allowing more sound wave energy to penetrate into the interior of the dam body, thereby more accurately reflecting the stress state inside the dam body.
