Abstract
Description
Technical Field
[0001] This utility model relates to the field of data acquisition technology, specifically a multi-source data acquisition device based on distributed internal stress in tunnels. Background Technology
[0002] The distributed internal stress multi-source data acquisition device for tunnels is a device used for monitoring the health of tunnel structures. It can collect key parameter data such as stress, strain, temperature, and humidity inside the tunnel in real time, and achieve high-precision monitoring of parameters such as tunnel deformation and convergence through multiple sensors. This data is crucial for assessing the health status of the tunnel structure and providing early warning of potential structural problems, which helps ensure the safe and stable operation of the tunnel.

[0027] Please see Figure 1-6 This utility model provides a technical solution:
[0028] A multi-source data acquisition device for distributed internal stress in tunnels includes a data acquisition body 1. A protective component 2 is fixedly connected to the right side of the data acquisition body 1. A wiring component 3 is installed inside the protective component 2. The protective component 2 includes a protective shell 21. A receiving groove 22 and a guide groove 23 are formed inside the protective shell 21. The inner side of the receiving groove 22 fits against the outer side of a rubber plug 24. A first rigid plate 25 is fixedly connected to the right side of the rubber plug 24. A sealing airbag 2 is fixedly connected to the lower end of the rubber plug 24. 6. A pin 27 is fixedly connected to the bottom of the first rigid plate 25. The pin 27 is inserted into the inside of the slot 28. The slot 28 is opened at the upper end of the second rigid plate 29. The wiring assembly 3 includes a wiring plate 31. The front and rear ends of the wiring plate 31 are fixedly connected to sliding rail plates 32. The left side of the wiring plate 31 is fixedly connected to the right side of the pull rope 34. The pull rope 34 is wound and fixed to the outside of the turntable 35. The turntable 35 is rotatably connected to the inside of the ear seat 37 through the limiting ring 36. A spring 38 is fixedly connected to the inside of the ear seat 37.
[0029] As a further implementation of this solution, the left side of the protective shell 21 is fixedly connected to the right side of the data acquisition unit 1. The receiving groove 22 extends through the inner side of the protective shell 21 on both sides and is connected to the guide slide 23. The rubber plug 24 has a groove on the inner side near the sealing airbag 26. The right side of the rubber plug 24 has a U-shaped structure. The lower end of the first hard plate 25 has a groove. The bottom end of the rubber plug 24 is flush with the bottom end of the first hard plate 25. Through the above settings, this unique structural design allows the device to fit tightly during assembly, effectively reducing the intrusion of moisture and impurities, providing a solid foundation for the sealing and stable connection of the circuit, and ensuring the stable operation of the equipment in a humid environment.
[0030] As a further implementation of this solution, a rubber plug 24 is fixed on the left side of the second rigid plate 29. The two rubber plugs 24 are fitted together. There are two sealing airbags 26, which are fitted together. The outer sides of the two rubber plugs 24 are fitted with the inner side of the receiving groove 22. Through the above arrangement, this tight fitting design not only enhances the sealing performance of the device, but also improves the stability of the circuit connection.
[0031] As a further implementation of this solution, the number of guide grooves 23 is the same as the number of sliding rails 32. The sliding rails 32 are slidably connected to the inner side of the guide grooves 23. Through the above arrangement, this matching of quantities and sliding connection design makes the device more flexible in operation and can effectively improve the efficiency and stability of the line connection.
[0032] As a further implementation of this solution, the right side of the data acquisition unit 1 is fixedly connected to the left side of the spiral connecting line 33. The data acquisition unit 1, the spiral connecting line 33 and the terminal block 31 are electrically connected. The middle part of the spiral connecting line 33 has a spiral structure. Through the above settings, the spiral structure design not only enhances the extension performance of the spiral connecting line 33, but also improves the flexibility and stability of the line connection, providing an important guarantee for the high efficiency of data transmission.
[0033] As a further implementation of this solution, one end of the pull rope 34 is fixedly connected to the outside of the turntable 35, a limiting rotating hole is opened on the inside of the ear seat 37, the limiting ring 36 is in the shape of a ring, one end of the turntable 35 extends into the limiting rotating hole of the ear seat 37, the outside of the turntable 35 is fixedly connected to the inside of the spring 38, and the left side of the ear seat 37 is fixedly connected to the right side of the data acquisition unit body 1. Through the above settings, this structural design enables the device to achieve precise limiting and automatic reset during rotation, effectively improving the stability and reliability of the device.
[0034] Workflow: When an external line needs to be electrically connected to the data acquisition unit 1, pull the terminal block 31 to the right. The terminal block 31 is slidably connected to the inside of the guide groove 23 via the sliding rail 32. At this time, the terminal block 31 pulls the spiral connecting wire 33 to extend. The shape design of the spiral connecting wire 33 provides a certain degree of extension performance. The terminal block 31 drives the pull rope 34 to pull out, and the pull rope 34 drives the turntable 35 to rotate. The turntable 35 is rotatably connected to the inside of the ear seat 37 via the limiting ring 36, which limits the rotation of the turntable 35. The turntable 35 drives the spring 38 to undergo elastic deformation, and the spring 38 automatically resets the rotation angle of the turntable 35. The movable design of the terminal block 31 not only facilitates wiring, but also, when the terminal block 31 is pulled back by the pull rope 34, the terminal block 31 is located inside the protective shell 21, so that the connecting wire part of the terminal block 31 is inside the receiving groove 22, providing a suitable location for the wiring. The sealing provides a good foundation. After the wiring is installed, the terminal block 31 is reset inside the protective housing 21. At this time, the plug 27 is aligned with the slot 28, and the two sealing airbags 26 are aligned with the wiring. The two sealing airbags 26 compress the wiring, and the sealing airbags 26 deform after compression. Through the deformation of the two sealing airbags 26 and their tight contact with the wiring, the entry of external moisture and impurities into the receiving groove 22 can be significantly reduced, providing a safety guarantee for the data transmission of the data acquisition unit 1. After the two rubber plugs 24 are attached, the rubber plugs 24 are inserted into the receiving groove 22. After insertion, the friction between the rubber plugs 24 and the protective housing 21 plays a role in limiting the rubber plugs 24. Based on the above principles, the device improves the stability of the wiring after assembly. At the same time, the assembled device can significantly reduce the intrusion of moisture, thereby preventing the terminals from getting damp and improving the safety of the operator.
[0035] Although embodiments of the present invention have been shown and described, 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.
