[0002] As a non-contact monitoring method, radar detection technology has unique advantages in monitoring tunnel micro-deformation. It can quickly and over a large area acquire deformation information of the tunnel surface, without being limited by environmental factors such as light and weather. It has high monitoring efficiency and accuracy. Micro-deformation radar can adapt to short-range deformation monitoring in complex environments. By installing micro-deformation radar on complex tunnel cross-sections, automated real-time deformation monitoring of cross-section arch subsidence and surrounding displacement can be achieved. As an important component of the radar detection system, the ease of installation, stability and accuracy of the radar detection target device directly affect the performance of the entire monitoring system.
[0003] Currently, traditional tunnel micro-deformation radar detection target devices typically use bolt or thread tightening adjustment to adjust the height of the target and radar during installation. This adjustment method requires operators to repeatedly tighten or loosen the bolts or threads using tools, which is cumbersome and time-consuming, affecting installation efficiency. Furthermore, the bolts or threads may loosen, affecting the stability of the target and radar. In addition, with this bolt or thread tightening adjustment method, it is difficult to ensure that the target and radar body can be quickly and accurately aligned during actual installation, requiring multiple rotations and repeated adjustments, further reducing the overall assembly efficiency of the device. Therefore, this utility model proposes a tunnel micro-deformation radar detection target device. Utility Model Content

[0023] 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.
[0024] Example
[0025] Please see Figures 1 to 5 This is an embodiment of the present invention, which provides a technical solution: a tunnel micro-deformation radar target detection device, comprising...
[0026] The target 1 and the radar body 2 are installed at the bottom of the tunnel wall 4. The radar body 2 is aligned with the target 1. Adjustment brackets 3 are provided between the target 1 and the tunnel wall 4, and between the radar body 2 and the tunnel wall 4.
[0027] The adjustment bracket 3 includes a bottom column sleeve 31 fixed to the top surface of the target 1 or the radar body 2, and a top support column 32 movably disposed at the top of the bottom column sleeve 31. A fixing base plate 321 is welded and fixed to the top of the top support column 32, and the fixing base plate 321 is anchored to the bottom surface of the tunnel wall 4. The bottom column sleeve 31 has a column groove 311 adapted to the top support column 32, and the bottom end of the top support column 32 slides within the column groove 311.
[0028] The adjusting bracket 3 also includes a plug-in structure disposed between the bottom column sleeve 31 and the top support column 32. The plug-in structure includes a rectangular plug 331, an end block 339 welded and fixed to the left end of the rectangular plug 331, a C-shaped movable seat 332 movably mounted on the right side surface of the bottom column sleeve 31, and multiple adjusting holes 338 through the surface of the top support column 32 corresponding to the rectangular plug 331. The end block 339 fits against the left side surface of the bottom column sleeve 31, and the right end of the rectangular plug 331 penetrates through the top end of the bottom column sleeve 31 and passes through one of the adjusting holes 338 to the right side surface of the bottom column sleeve 31. The movable seat 332 is located at the bottom right end of the rectangular insert 331. A right-angled triangular locking block 333 is welded and fixed to the top surface of the C-shaped movable seat 332. A rectangular slot 334 is provided on the bottom right end of the rectangular insert 331 for the right-angled triangular locking block 333 to be inserted. The right-angled triangular locking block 333 can stably limit the rectangular insert 331, ensuring the insertion stability of the rectangular insert 331, thereby ensuring the limiting stability between the bottom column sleeve 31 and the top support column 32. In actual installation, if the height of the target 1 and the radar body 2 needs to be adaptively adjusted, it is only necessary to move the C-shaped movable seat 332. Pressing down causes the right-angled triangular locking block 333 to move out of the rectangular locking slot 334, releasing the restriction on the rectangular insert 331. At this point, the rectangular insert 331 can be pulled out from between the bottom post sleeve 31 and the top support column 32. Then, slide the bottom post sleeve 31 up and down to change the height of the target 1 and the radar body 2. Once the appropriate height is achieved, insert the rectangular insert 331 again through the top of the bottom post sleeve 31 and through other adjustment holes 338 until the right end of the rectangular insert 331 extends to the right side surface of the bottom post sleeve 31, and the right-angled triangular locking block 333 engages in the rectangular locking slot 334. The system quickly completes the positioning between the bottom column sleeve 31 and the top support column 32, and quickly adjusts the height of the target 1 and the radar body 2. Since both the target 1 and the radar body 2 are equipped with identical adjustment brackets 3 on their tops, and the spacing between their adjacent adjustment holes 338 is interconnected, when actually adjusting the height of the target 1 and the radar body 2, the rectangular blocks 331 on the two adjustment brackets 3 can be inserted through the adjustment holes 338 at the same height to quickly achieve synchronous adjustment of the height of the target 1 and the radar body 2. The target 1 and the radar body 2 can maintain alignment and synchronization more quickly, further improving installation efficiency.
[0029] In this embodiment, preferably, the top two sides of the bottom column sleeve 31 are provided with through holes for the column groove 311 to pass through.
[0030] In this embodiment, preferably, the insertion structure further includes a support plate 337 welded and fixed to the right side surface of the bottom column sleeve 31 and located at the bottom of the C-shaped movable seat 332. A guide rod 336 is fixed to the bottom surface of the C-shaped movable seat 332, and the bottom end of the guide rod 336 extends movably through to the bottom of the support plate 337. The guide rod 336 can play a guiding and supporting role during the up-and-down sliding process of the C-shaped movable seat 332. A spring 335 is also sleeved between the surface of the guide rod 336 and the C-shaped movable seat 332 and the support plate 337. Under the pushing of the spring 335, the right-angled triangular locking block 333 can be stably locked in the rectangular locking slot 334 during daily use, ensuring the limiting stability of the rectangular insertion block 331, thereby ensuring the insertion stability of the rectangular insertion block 331 to the bottom column sleeve 31 and the top support column 32. This ensures the stability of the target 1 and the radar body 2 after installation. When the operator needs to quickly release the limiting of the rectangular insertion block 331 to realize the rectangular insertion... During the insertion and removal adjustment of block 331, simply press down the C-shaped movable seat 332 forcefully, applying a large downward pressure to the C-shaped movable seat 332. This causes the spring 335 to be compressed and undergo further elastic deformation, ultimately allowing the C-shaped movable seat 332 to move smoothly downwards with the right-angled triangular locking block 333. This allows the right-angled triangular locking block 333 to move out of the rectangular locking slot 334. Due to the unique right-angled triangular design of the right-angled triangular locking block 333, when the subsequent rectangular insert 331 penetrates the bottom post sleeve 31 and the top support post 32, the right end of the rectangular insert 331 will contact the inclined surface of the right-angled triangular locking block 333 and compress the right-angled triangular locking block 333. This causes the C-shaped movable seat 332 to be subjected to downward compressive force, making it easier for the right end of the rectangular insert 331 to pass over the right-angled triangular locking block 333 during insertion, thus completing the insertion limit of the bottom post sleeve 31 and the top support post 32, further improving the ease of operation.
[0031] In this embodiment, preferably, the bottom end of the spring 335 abuts against the top surface of the support plate 337, and the top end of the spring 335 abuts against the bottom surface of the C-shaped movable seat 332, ensuring that the spring 335 applies an upward pushing force to the C-shaped movable seat 332 at all times, and ensuring that the right-angled triangular locking block 333 is always locked in the rectangular locking slot 334.
[0032] In this embodiment, preferably, a T-shaped slider 3321 is welded and fixed to the left side surface of the C-shaped movable seat 332, and a T-shaped groove 312 corresponding to the T-shaped slider 3321 is opened on the right side surface of the bottom column sleeve 31. The T-shaped slider 3321 slides in the T-shaped groove 312, which can further guide and support the C-shaped movable seat 332 when it slides up and down.
[0033] In this embodiment, preferably, the surface of the support plate 337 is provided with a circular rod hole for the guide rod 336 to pass through, so that the guide rod 336 can pass through smoothly and slide subsequently.
[0034] In this embodiment, preferably, the guide rod 336 passes through the inner center of the spring 335, so that the guide rod 336 does not affect the normal extension and contraction of the spring 335, and the guide rod 336 can also limit the spring 335 to prevent the spring 335 from falling off the bottom of the C-shaped movable seat 332.
[0035] In this embodiment, preferably, anchor bolts are provided at all four corners of the fixed base plate 321, and the top of the anchor bolts penetrates the fixed base plate 321 and is fixed to the bottom surface of the tunnel wall 4.
[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
