Description

Technical Field

[0001] The invention belongs to the technical field of gravity dam topographic survey, and specifically refers to a topographic survey device used for concrete gravity dam modeling. Background Art

[0002] A concrete gravity dam is a dam structure that resists water pressure and other external forces by its own weight. It is mainly made of concrete and is widely used in water conservancy and hydropower projects. Gravity dams usually have high stability and durability and can function effectively under various geological conditions. However, in order to ensure the design and construction quality of gravity dams, accurate surveys and modeling of the dam site and its surrounding terrain are necessary. This is of great significance for determining the design parameters of the dam, evaluating the geological conditions of the dam site, and predicting the behavior of the dam during operation.

[0003] When conducting topographic surveys for concrete gravity dam modeling, geological radar has become a commonly used surveying tool due to its non-destructive, high-resolution and real-time imaging advantages. Geological radar detects underground structures by emitting electromagnetic waves and receiving reflected signals. However, current survey methods often ignore the impact of surface vegetation on geological radar signals. Specifically, moisture and organic matter in surface vegetation absorb the electromagnetic waves emitted by geological radar, resulting in signal attenuation and scattering. This signal attenuation not only reduces the detection depth of geological radar, but also significantly affects the resolution and accuracy of detection data.

[0004] The presence of vegetation makes it difficult for geological radar to effectively penetrate the surface, especially in areas with dense vegetation and high moisture content, where the attenuation of electromagnetic waves is more obvious. Due to the absorption of vegetation, the radar signal has been significantly weakened before reaching the underground target, resulting in increased noise in the detection results and reduced signal quality. These problems make the identification and interpretation of underground structures during the survey more complicated, affecting the accuracy of concrete gravity dam modeling. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a terrain survey equipment for concrete gravity dam modeling. Through the signal-enhanced surface preprocessing mechanism, signal attenuation can be reduced. Vegetation, especially vegetation containing a large amount of water, will absorb and attenuate the electromagnetic waves of the geological radar.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a terrain survey device for concrete gravity dam modeling, which achieves the following beneficial effects: (1) In order to solve the problem that the presence of vegetation makes it difficult for geological radar to effectively penetrate the surface, especially in areas with dense vegetation and high water content, the attenuation of electromagnetic waves is more obvious. The present invention provides a signal-enhanced surface preprocessing mechanism that can reduce signal attenuation. Vegetation, especially vegetation containing a large amount of water, will absorb and attenuate the electromagnetic waves of the geological radar. After clearing the vegetation, the signal attenuation can be reduced and the penetration depth of the radar signal can be increased, thereby better detecting the underground structure.

[0017] (2) Noise can be reduced through signal-enhancing surface preprocessing mechanisms. Surface vegetation can cause electromagnetic wave scattering, increase noise and irregular reflections. Clearing vegetation can reduce these interferences and improve signal clarity and data interpretability.

[0018] (3) False echoes can be reduced by using a signal-enhanced surface preprocessing mechanism. Vegetation may cause false echo signals and interfere with the detection of underground targets. Clearing the vegetation can reduce the generation of false signals.

[0019] (4) The reflected signal can be enhanced through the signal-enhanced surface preprocessing mechanism. After clearing the vegetation, the geological radar can contact the surface more directly, thereby enhancing the strength of the reflected signal, improving the resolution of the data, and improving the image quality. By reducing vegetation interference, clearer and more continuous radar images can be obtained, which is convenient for identifying underground structures and anomalies.

[0020] (5) The signal-enhanced surface preprocessing mechanism can reduce the processing workload and the interference signals caused by vegetation. The filtering and correction steps in the data processing process are also reduced accordingly, which improves the overall work efficiency.

[0021] (6) The frozen vegetation embrittlement component can quickly make the vegetation embrittled, thereby greatly reducing the cleaning time. The embrittled vegetation becomes fragile, and the force required for cleaning with a cutting knife is smaller, and the cutting efficiency is higher.

[0022] (7) The frozen vegetation embrittlement component can be easily cleaned, and the embrittled vegetation is easier to break and remove, reducing physical labor compared to traditional methods.

[0023] (8) Through the freezing type vegetation embrittlement component, the liquid nitrogen atomization treatment is relatively localized, avoiding large-scale mechanical disturbance and reducing damage to the surface soil; precise control, the ultrasonic atomizer can accurately control the spraying range of liquid nitrogen to avoid affecting non-target areas.

[0024] (9) The gravity-compensated self-adjusting survey mechanism is set up. When the road surface encounters bumps, under the gravity of the gravity block, the sleeve rotates on the fixed part to offset the front and rear shaking, and the pulley rotates in the annular groove to offset the left and right shaking.

[0025] (10) The rotation of the roller drives the spiral blade 1 and the spiral blade 2 to rotate, thereby cleaning the cut vegetation on both sides and cleaning the ground surface. BRIEF DESCRIPTION OF THE DRAWINGS
