Description

Technical Field

[0001] This utility model relates to the field of ice and snow physical property detection technology, specifically a solid ice and snow detection device based on pressure feedback. Background Technology

[0002] The solidity of ice and snow is a core indicator reflecting its physical and mechanical properties, and is directly related to traffic safety, the antifreeze design of engineering structures, and the scientific nature of outdoor operation planning.

[0003] Currently, existing ice and snow hardness testing technologies rely on workers tapping or stepping on the ice and snow surface with hand tools, judging the hardness level based on experience. While this method is simple to operate, it is highly subjective, prone to large errors, and cannot quantify data. Furthermore, it cannot perform graded testing for different stress scenarios. Moreover, while devices that use a compression structure with fixed output pressure and pressure sensors to collect data can obtain quantified pressure values, they lack a design to adapt to different stress levels. The fixed output pressure of the hydraulic rod can easily cause excessive compression and damage, leading to distorted test data that cannot accurately reflect the hardness. Therefore, existing technologies lack a graded pressure application mechanism for ice and snow of different hardness, cannot meet the multi-level stress testing needs from loose snow to hard ice, and are prone to relying on subjective experience or single pressure or image data, failing to achieve multi-faceted verification.

[0004] To address these issues, this invention provides a solid ice and snow detection device based on pressure feedback. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a solid ice and snow detection device based on pressure feedback, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid ice and snow detection device based on pressure feedback, comprising a support, a hydraulic rod fixedly connected to the support, a compression block fixedly connected to the output end of the hydraulic rod, and a pressure sensor disposed within the compression block; a slide rail fixedly connected to the support, a moving block slidably connected to the slide rail, and a placement box for holding ice and snow samples fixedly connected to the moving block; a first camera frame and a second camera frame fixedly connected to the support, a first camera fixedly connected to the first camera frame, and a second camera fixedly connected to the second camera frame; a hydraulic rod pressure regulating component is configured on the hydraulic rod, the hydraulic rod pressure regulating component including an overflow valve and a pressure regulating knob.

[0007] Furthermore, a fixing frame is also fixedly connected to the bracket, and the fixing frame is connected in cooperation with the hydraulic rod.

[0008] Furthermore, a handle is fixedly connected to the side end of the placement box.

[0009] Furthermore, the pressure sensor is embedded in the end face of the extrusion block facing the placement box, and the sensing surface of the pressure sensor is flush with the extrusion surface of the extrusion block.

[0010] Furthermore, the lens axis of the first camera is oriented towards the rear side of the placement box.

[0011] Furthermore, the lens axis of the second camera faces the side of the placement box, and both cameras are equipped with a force level synchronization marking module.

[0012] Beneficial effects: This invention provides a solid ice and snow detection device based on pressure feedback. Compared with the prior art, it has the following advantages: (1) A solid ice and snow detection device based on pressure feedback, which can flexibly adjust the output pressure according to the estimated solidity of the sample through the overflow valve and pressure adjustment knob in the hydraulic rod pressure adjustment component, realize graded pressure application, avoid excessive squeezing and damage to loose samples, and meet the detection pressure requirements of hard samples, thereby improving the adaptability to different types of ice and snow samples.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figure 1-4 A solid ice and snow detection device based on pressure feedback includes a support 1, a hydraulic rod 2 fixedly connected to the support 1, a compression block 12 fixedly connected to the output end of the hydraulic rod 2, and a pressure sensor disposed inside the compression block 12; a slide rail 11 fixedly connected to the support 1, a moving block 10 slidably connected to the slide rail 11, and a placement box 8 for holding ice and snow samples fixedly connected to the moving block 10; a first camera frame 4 and a second camera frame 6 fixedly connected to the support 1, a first camera 5 fixedly connected to the first camera frame 4, and a second camera 7 fixedly connected to the second camera frame 6; a hydraulic rod pressure regulating component is configured on the hydraulic rod 2, the hydraulic rod pressure regulating component including an overflow valve and a pressure regulating knob.

[0018] A fixing frame 3 is also fixedly connected to the bracket 1, and the fixing frame 3 is connected in conjunction with the hydraulic rod 2.

[0019] A handle 9 is fixedly connected to the side of the placement box 8.

[0020] The pressure sensor is embedded in the end face of the extrusion block 12 facing the placement box 8, and the sensing surface of the pressure sensor is flush with the extrusion surface of the extrusion block 12.

[0021] The lens axis of the first camera 5 faces the rear side of the placement box 8.

[0022] The lens axis of the second camera 7 is oriented to the side of the placement box 8.

[0023] Working process: First, place the ice and snow sample to be tested into the placement box 8. The operator pushes the handle 9 on the side of the placement box 8 to move the bottom moving block 10 along the slide rail 11 on the bracket 1. The placement box 8 is then precisely aligned with the squeezing block 12 above to complete the sample positioning.

[0024] Based on the estimated firmness of the ice and snow sample, the output pressure is adjusted by the pressure adjustment knob on the hydraulic rod 2. When the knob is adjusted, it will be linked to the overflow valve to control the output pressure of the hydraulic rod 2, so as to achieve graded pressure to adapt to different samples.

[0025] Start the hydraulic rod 2, whose output end pushes the extrusion block 12 vertically downward until the extrusion surface of the extrusion block 12 contacts the surface of the ice and snow sample, and continuously applies pressure.

[0026] Since the pressure sensor is embedded in the end face of the extrusion block 12 facing the placement box 8, and the sensing surface is flush with the extrusion surface, the sensor can directly and without deviation collect the extrusion pressure data during the extrusion process; the more solid the ice and snow sample is, the stronger the force resisting extrusion, and the greater the pressure value collected by the sensor.

[0027] While the extrusion block 12 applies pressure, two cameras are simultaneously activated to collect sample status from different angles. The image data can intuitively reflect the physical morphological changes of the sample, and the pressure data collected by the pressure sensor is synchronously transmitted to the back-end processing system along with the image data collected by the two cameras.

[0028] If the pressure value is high and the sample in the image has small deformation and no obvious cracks, it indicates that the ice and snow are of high solidity; if the pressure value is low and the sample in the image breaks rapidly and has a large deformation range, it indicates that the ice and snow are of low solidity. The final output is the solidity level of the ice and snow sample.
