[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a tunnel lining detection device, including a tunnel lining detector 1 and a data transmission connector 6. The top surface of the tunnel lining detector 1 has a receiving square groove 2 and a combined square groove 3, with the combined square groove 3 located above the receiving square groove 2. Positioning grooves 4 are formed on both sides of the top surface of the tunnel lining detector 1, and magnetic suction plates 5 are installed inside the positioning grooves 4. The data transmission connector 6 is installed inside the receiving square groove 2 and is embedded and fixedly installed on the tunnel lining detector 1. A hand-held grip 7 is symmetrically fixedly installed on the top surface of the tunnel lining detector 1. A connecting square plate 8 is installed inside the combined square groove 3, and a first through hole 9 is formed on the connecting square plate 8. A translational slide groove 10 is provided at the center of the right end of the connecting square plate 8, and a limiting rod 11 is provided inside the translational slide groove 10. The limiting rod 11 is fixedly installed on the connecting square plate 8. A sealing partition 12 is installed on the outside of the hand grip 7, and a limiting block 13 is provided on the bottom right end of the sealing partition 12. The limiting block 13 is located inside the translational slide groove 10, and the limiting block 13 is connected to the limiting rod 11. Positioning blocks 14 are provided on both sides of the right end frame of the sealing partition 12, and the positioning blocks 14 are located inside the positioning groove 4. A magnetic column 15 is provided at the center of the positioning block 14. A second through hole 16 is provided on the sealing partition 12, and an anti-slip strip 17 is provided on the top left end of the sealing partition 12.

[0027] The magnetic suction plates 5 are symmetrically distributed inside the positioning groove 4, and the magnetic suction plates 5 are connected to the tunnel lining detector 1 by embedding and fixing. The magnetic suction plates 5 are connected to the magnetic column 15 by magnetic adsorption. Through the magnetic adsorption between the magnetic suction plates 5 and the magnetic column 15, the position of the subsequent sealing partition 12 after sliding displacement can be stabilized.

[0028] The connection between the connecting square plate 8 and the combined square groove 3 is by embedding and fixing, and the connection between the connecting square plate 8 and the sealing partition 12 is by sliding and fitting. The sealing partition 12 is set with an "L" shaped structure, which makes it easy for the connecting square plate 8 to be fixed inside the combined square groove 3. At the same time, the sealing partition 12 can move on the connecting square plate 8, which facilitates sealing and unsealing.

[0029] The limiting block 13 and the sealing partition 12 are integrated into one structure. The limiting block 13 is connected to the translation slide 10 and the limiting rod 11 by sliding connection. The top surface of the sealing partition 12 is flush with the top surface of the tunnel lining detector 1. The sealing partition 12 can maintain the stability of translation by sliding the limiting block 13, and avoid loosening and falling off.

[0030] The sealing partition 12 and the positioning block 14 are integrated into one structure. The positioning block 14 is connected to the magnetic column 15 by embedding and fixing. The positioning block 14 is connected to the positioning groove 4 by sliding connection. The sealing partition 12 can drive the positioning block 14 to slide and move, so that the sealing partition 12 can drive the magnetic column 15 in the center of the positioning block 14 to magnetically attract the magnetic plates 5 in different positions.

[0031] The axis of the second through hole 16 is aligned with the axis of the first through hole 9. The second through hole 16 and the first through hole 9 are evenly distributed on the sealing partition 12 and the connecting square plate 8, respectively. The diameters of the second through hole 16 and the first through hole 9 are larger than the diameter of the data transmission connector 6. This allows the external data cable interface to be combined with the data transmission connector 6 after the second through hole 16 and the first through hole 9 are aligned, enabling real-time data transmission.

[0032] The anti-slip strip 17 and the sealing partition 12 are integrated into one structure, and the anti-slip strip 17 is evenly distributed on the sealing partition 12. Based on the anti-slip strip 17 on the sealing partition 12, it is convenient to manually move the sealing partition 12.

[0033] Working principle: According to Figure 1-5 First, staff can move the tunnel lining inspection instrument 1 by hand using the handle 7. When the tunnel lining inspection instrument 1 needs to be used, the sealing partition 12 can be moved by the anti-slip strip 17. The sealing partition 12 slides on the outside of the connecting square plate 8. The sealing partition 12 drives the limiting block 13 to slide and move within the translation groove 10 and on the outside of the limiting rod 11. At the same time, the sealing partition 12 drives the positioning block 14 to move inside the positioning groove 4. After the positioning block 14 drives the magnetic column 15 to separate from the magnetic suction plate 5, the positioning block 14 drives the magnetic column 15 to... On the other side, the magnetic suction plate 5 magnetically attracts the sealing partition 12, facilitating its unfolding. Simultaneously, the second through hole 16 on the sealing partition 12 aligns with the first through hole 9 on the connecting square plate 8. Then, the external data cable interface can be connected to the data transmission connector 6 for real-time data transmission. The tunnel lining detector 1 is then pressed against the outer surface of the tunnel lining by the hand grip 7 for testing. This is the entire working process of the device. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] 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.
