Description

Technical Field

[0001] This utility model relates to the technical field of multi-sensor mounting brackets, and in particular to a mounting bracket for multi-sensor holographic sensing in underground space. Background Technology

[0002] Holographic sensing of underground spaces (such as subway tunnels, integrated utility tunnels, and underground parking lots) relies on the coordinated monitoring of multiple types of sensors (such as displacement sensors, temperature and humidity sensors, and gas sensors). The installation stability and angular accuracy of these sensors directly affect the reliability of data acquisition. Existing fixed devices have many limitations. Existing mounting brackets have poor adaptability. Underground spaces often have curved walls and concrete structures, making it difficult for traditional brackets to fit snugly, which can easily cause sensor displacement due to vibration. They also lack adjustment flexibility, as the sensor angles and heights are fixed and cannot be adjusted in real time according to monitoring needs, making it difficult to cover monitoring blind spots in complex spaces. Cable management is chaotic, with data cables and power cables from multiple sensors tangled together, making them susceptible to short circuits due to the damp underground environment. Furthermore, their protection capabilities are weak, with sensors and connecting components easily corroded by dust and moisture, shortening their service life. Therefore, we propose a mounting bracket for multi-sensor holographic sensing in underground spaces. Utility Model Content

[0003] The purpose of this invention is to provide a mounting bracket for a multi-sensor holographic perception system in underground space, which solves the existing problems.

[0005] Preferably, the telescopic support leg includes an inner rod, an outer cylinder, an adjusting bolt, and an anti-slip pad. The outer cylinder is fixedly installed at the bottom of the main mounting base, the inner rod is slidably installed inside the outer cylinder, the adjusting bolt is threaded on the outer side of the outer cylinder and abuts against the inner rod, and the anti-slip pad is fixedly installed at the bottom of the inner rod.

The fixed base is fixedly installed on the top of the main mounting base, the rotating disk is rotatably installed inside the fixed base, the angle scale is fixed on the outside of the fixed base, and the positioning pin passes through the rotating disk and is engaged with the fixed base.

The height adjusting block is fixed to the outside of the sensor mounting plate, and the height adjusting block is slidably installed on the inside of the L-shaped bracket. The clamping bolt is threaded onto the front of the L-shaped bracket, and the buffer pad is fixed to the inside of the L-shaped bracket.

[0008] Preferably, the sensor mounting plate has multiple weight-reduction holes on its inner side, and a cable management ring is fixedly installed at the edge of the sensor mounting plate, with a rubber protective ring provided on the inner side of the cable management ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a mounting bracket for a multi-sensor holographic sensing system in underground space. The main mounting base, through the cooperation of the inner rod and outer cylinder of the telescopic support leg, can adjust its height according to the flatness of the ground.

The height adjustment block of the sensor fixing component slides along the L-shaped card seat to adapt to sensors of different thicknesses. This utility model discloses a mounting bracket for multiple sensors used in underground space holographic sensing. The cable management ring and rubber protective ring on the sensor mounting plate can classify and store the multi-sensor cables, avoiding tangling and wear. The rubber protective ring can also buffer cable vibration and reduce damage to the outer sheath caused by friction. Compared with the traditional messy cable layout, it effectively reduces the probability of faults such as short circuits and poor contact. The moisture-proof sponge in the environmental protection box can absorb moisture, and the heat dissipation holes can maintain air circulation, effectively resisting the corrosion of the sensors in the high humidity and dusty underground environment. The buffer pad of the L-shaped bracket can reduce the impact of vibration on the sensors. Compared with the traditional unprotected design, it can significantly extend the service life of the sensors. Attached Figure Description
