Description

Technical Field

[0001] This utility model relates to the field of rock and soil geological radar technology, and in particular to an anti-interference protection device for rock and soil advanced prediction geological radar. Background Technology

[0002] Geotechnical ground-penetrating radar (GPR) is a core detection device in geotechnical engineering investigation, tunnel construction, slope treatment, and other fields. Currently, there are many types of GPR for geotechnical ground-penetrating radar, with the two-handed GPR being one of the most widely used. During operation, the operator must hold the two handles on the device body with both hands, ensuring the radar detection surface is in close contact with the soil and rock surface to obtain accurate detection data.

[0003] However, in the existing structural design of handheld ground-penetrating radar, there is a lack of effective protective mechanisms above the equipment. When there are situations such as falling rocks or small pieces collapsing in the soil and rock above the construction environment, the falling objects can easily directly hit the radar detection body or the operator's hands. This may not only interfere with the stability of the radar detection signal and affect the accuracy of the detection data, but may also cause physical damage to the equipment (such as scratches on the detection panel or damage to the internal circuitry). At the same time, it poses a potential threat to the safety of the operator's hands. In practical engineering applications, there are obvious limitations and safety hazards. In order to solve the above problems, this utility model proposes an anti-interference protection device for ground-penetrating radar for advanced prediction of soil and rock. Utility Model Content

[0004] The main purpose of this utility model is to provide an anti-interference protection device for geological radar for advanced prediction of soil and rock, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An anti-interference and protection device for geotechnical early warning grounding radar includes a connecting plate with two connecting bolts running through its upper end. The connecting plate is equipped with a shielding mechanism for shielding the grounding radar. The shielding mechanism includes two fixed blocks fixedly connected to the upper end of the connecting plate. A rotating shaft is rotatably connected to both fixed blocks. A rotating block is fixedly connected to the side wall of the rotating shaft, and a protective plate is fixedly connected to the side wall of the rotating block. The side wall of one of the fixed blocks is connected to the rotating shaft through the connecting mechanism.

[0006] Preferably, the connecting mechanism includes a torsion spring fixedly connected to the side wall of the fixed block, and a fixing ring is installed at the other end of the torsion spring, the fixing ring being fixedly connected to the rotating shaft.

[0007] Preferably, a protective cloth is fixedly connected to the side wall of the protective plate, and the other end of the protective cloth is fixedly connected to the upper end of the connecting plate.

[0008] Preferably, the upper end of the protective plate has multiple through holes, and the multiple through holes are arranged at equal intervals.

[0009] Preferably, the protective plate is fitted with a protective sleeve on its side wall, and the protective sleeve is made of rubber material.

[0010] Preferably, the protective plate is made of plastic, and the protective sleeve has a U-shaped cross-section.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This device is equipped with a shielding mechanism. The connecting plate and connecting bolts achieve a stable and compatible connection between the protective device and the radar. The protective plate blocks large pieces of gravel, and the protective cloth blocks small pieces of gravel, forming a comprehensive protection for the operator's hands and the radar body, solving the core problems of gravel injuring personnel and interfering with equipment. 2. This device is equipped with a connecting mechanism, and a torsion spring ensures that the protective plate always maintains a protective posture, while the protective sleeve buffers the impact force, thereby improving the practicality of the device. 3. This device is equipped with through holes.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4As shown, the anti-interference protection device for geotechnical advanced prediction ground-penetrating radar includes a connecting plate 1, with two connecting bolts 2 penetrating through the upper end of the connecting plate 1. The ground-penetrating radar is equipped with a fixing plate for installing the connecting bolts 2. Figure 4 As shown), the connecting plate 1 is provided with a shielding mechanism for blocking the ground-penetrating radar. The shielding mechanism includes two fixed blocks 5 fixedly connected to the upper end of the connecting plate 1. A rotating shaft 4 is rotatably connected to both fixed blocks 5. A rotating block 6 is fixedly connected to the side wall of the rotating shaft 4. A protective plate 3 is fixedly connected to the side wall of the rotating block 6. The side wall of one of the fixed blocks 5 is connected to the rotating shaft 4 through a connecting mechanism.

[0016] In this utility model, the connecting mechanism includes a torsion spring 8 fixedly connected to the side wall of the fixed block 5, and a fixing ring 9 is installed at the other end of the torsion spring 8. The fixing ring 9 is fixedly connected to the rotating shaft 4, so that the protective plate 3 can always protect the front of the ground radar handle.

[0017] In this utility model, a protective cloth 11 is fixedly connected to the side wall of the protective plate 3, and the other end of the protective cloth 11 is fixedly connected to the upper end of the connecting plate 1. The protective cloth 11 is made of wear-resistant material. The core advantage of this design is to fill the gap between the protective plate 3 and the connecting plate 1. In existing two-handed radar equipment without protective structure, the gap between the handle and the radar body makes it easy for small pieces of gravel to pass through. The protective cloth 11 can completely block small pieces of gravel, which not only prevents gravel from injuring the operator's hands, but also prevents gravel from entering the radar or impacting the radar shell and causing equipment interference, thus improving the protection range. The wear-resistant material is suitable for the dusty and frequent friction environment in rock and soil operations, extending the service life of the protective cloth 11 and avoiding frequent replacement.

[0018] In this utility model, the upper end of the protective plate 3 is provided with multiple through holes 10, which are equally spaced. The through hole 10 design can reduce weight and improve operating comfort. At the same time, the through hole 10 can reduce wind resistance during outdoor operations, prevent strong winds from causing the protective plate 3 to shake and affect operation, and further optimize the user experience.

[0019] In this utility model, a protective sleeve 7 is provided on the side wall of the protective plate 3. The protective sleeve 7 is made of rubber material. The rubber protective sleeve 7 has buffering and anti-slip properties, which can buffer the impact force of gravel and prevent operators from being scratched when they come into contact with the protective plate 3.

[0020] In this utility model, the protective plate 3 is made of plastic, which further reduces the weight. Combined with the through hole 10, it achieves "lightweight without sacrificing strength". The protective sleeve 7 has a U-shaped cross-section, and the rounded corners completely eliminate the safety hazards of sharp edges and corners. The U-shaped protective sleeve 7 can tightly wrap the side wall of the protective plate 3 to prevent it from falling off during use and ensure the continuous and stable protective effect.

[0021] After use, the working principle of this utility model is as follows: During device installation: The operator first places the connecting plate 1 in the preset installation position of the ground-penetrating radar, ensuring that the mounting holes of the connecting bolts 2 on the connecting plate 1 align with the fixing plate on the radar. Figure 4 (As shown) Align the mounting holes; then insert the two connecting bolts 2 through the mounting holes of the connecting plate 1 respectively, and screw them clockwise into the corresponding threaded holes of the radar fixing plate until the connecting bolts 2 are fully tightened, thus completing the stable connection between the connecting plate 1 and the ground-penetrating radar, ensuring that the protective device moves synchronously with the radar, and avoiding misalignment during use; Protective posture formation stage: After the connecting plate 1 is installed, the operator holds the two handles of the ground-penetrating radar with both hands; at this time, due to its own gravity, the protective plate 3 drives the rotating block 6 to rotate downward around the rotating shaft 4 (the rotating shaft 4 is rotatably connected between two fixed blocks 5, and the fixed blocks 5 are fixed to the upper end of the connecting plate 1) until the protective plate 3 is in contact with the upper area of ​​the radar handle in the vertical state, forming a "handle-protective plate 3" shielding structure, which isolates the operator's hands from the space above the radar; Protective function phase: When debris falls from the soil and rock above during the detection operation, the debris will first impact the protective plate 3. The protective sleeve 7 on the side wall of the protective plate 3 will first buffer the impact force and reduce the damage to the protective plate 3 caused by the debris. If the debris is small and falls from the gap between the protective plate 3 and the connecting plate 1, the protective cloth 11 (fixed to the side wall of the protective plate 3 and the upper end of the connecting plate 1) will block the debris and prevent it from hitting the operator's hands. At the same time, the protective plate 3 can prevent the debris from directly impacting the radar body, preventing interference with the detection signal or damage to the instrument. In addition, the torsion spring 8 between the fixing block 5 and the rotating shaft 4 (fixed to the rotating shaft 4 through the fixing ring 9) will generate a reverse elastic force after the protective plate 3 is impacted, pushing the rotating shaft 4 to drive the protective plate 3 to reset and quickly return to the initial protective position, ensuring effective protection when debris falls again.
