Chloride ion erosion will not only cause the corrosion of internal steel bars in concrete, but also reduce the overall strength of concrete, seriously affecting the service life of the project. Therefore, accurately measuring the chloride ion content and its diffusion coefficient in concrete is of great significance for evaluating and predicting the remaining life of concrete structures;

[0028] A partition plate 8 is fixed inside the powder extraction pipe 4, and a circular through hole adapted to the drill bit is opened inside the partition plate 8, so that the drill bit can penetrate through the inside of the circular through hole, so that the drill bit can extract powder from the detection site through the partition plate 8, and the powder can fall into the powder extraction pipe 4;

[0029] The telescopic hose 3 is sleeved on the outside of one end of the peripheral pipe 2, and the telescopic hose 3 and the peripheral pipe 2 are fixed by a circular clamp. Through the setting of the circular clamp, the telescopic hose 3 can be fixed on the outside of the peripheral pipe 2, so that the telescopic hose 3 can be disassembled, facilitating the subsequent maintenance and replacement of the telescopic hose 3;

[0030] A plurality of transverse sliders are fixed inside the peripheral pipe 2. Transverse chutes adapted to the transverse sliders are provided on the outside of the drill chuck 7. The peripheral pipe 2 and the drill chuck 7 are slidably connected through the cooperation of the transverse sliders and the transverse chutes, so that the drill chuck 7 can slide on the outside of the peripheral pipe 2, facilitating the installation of the peripheral pipe 2 on the outside of the drill chuck 7;

[0031] The limiting mechanism includes a plurality of circular cylinders 9. A plurality of circular cylinders 9 are fixed inside the peripheral pipe 2. A threaded rod 11 is threadedly connected inside the circular cylinder 9. A circular limiting column 12 is fixed to the bottom of the threaded rod 11. A hexagonal rotating block 10 is fixed to the top of the threaded rod 11. A circular groove adapted to the circular limiting column 12 is provided on the outside of the drill chuck 7. A clearance fit is provided between the circular limiting column 12 and the drill chuck 7 through the circular groove. When the circular limiting column 12 enters the inside of the circular groove, the sliding of the peripheral pipe 2 on the outside of the drill chuck 7 can be restricted, so that the peripheral pipe 2 can be fixed, enabling the peripheral pipe 2 to be installed on the outside of the drill chuck 7;

[0032] Here, the peripheral pipe 2 is slid to the outside of the drill chuck 7, and the hexagonal rotating block 10 is rotated. The rotation of the hexagonal rotating block 10, through the threaded connection of the threaded rod 11 and the circular cylinder 9, enables the circular limiting column 12 to move towards the drill chuck 7, so that the circular limiting column 12 can enter the inside of the circular groove, further restricting the movement of the peripheral pipe 2 on the outside of the drill chuck 7 and fixing the peripheral pipe 2;

[0033] The adjusting mechanism includes an L-shaped clamping plate 13. The L-shaped clamping plate 13 is located inside the depth positioning ruler limiter 6 and is slidably connected to the depth positioning ruler limiter 6. One end of the L-shaped clamping plate 13 is fixed with a rectangular push plate 14. The bottom of the L-shaped clamping plate 13 is fixed with a rectangular sliding plate 15. The rectangular sliding plate 15 is located inside the depth positioning ruler limiter 6 and is slidably connected to the depth positioning ruler limiter 6. Transverse optical rods 16 are slidably connected to both sides inside the rectangular sliding plate 15. A transverse rigid spring 17 is provided on one end of the rectangular sliding plate 15 and outside the transverse optical rod 16;

[0034] Tooth grooves are evenly arranged at one end of the depth positioning ruler 5. A tooth block adapted to the tooth grooves is fixed to one end of the L-shaped clamping plate 13 close to the depth positioning ruler 5. A clearance fit is provided between the depth positioning ruler 5 and the L-shaped clamping plate 13 through the tooth grooves and the tooth blocks, enabling the L-shaped clamping plate 13 to restrict the movement of the depth positioning ruler 5 inside the depth positioning ruler limiter 6;

[0035] A transverse through-hole is provided inside the rectangular sliding plate 15. The transverse smooth rod 16 is located inside the transverse through-hole and is slidably connected to the rectangular sliding plate 15 through the transverse through-hole. Through the setting of the transverse through-hole, the rectangular sliding plate 15 can slide outside the transverse smooth rod 16, and the movement of the rectangular sliding plate 15 causes the transverse rigid spring 17 to deform under force;

[0036] Here, when it is necessary to adjust the drilling sampling depth, press the rectangular push plate 14. The pressing of the rectangular push plate 14 enables the L-shaped clamping plate 13 to slide inside the depth positioning ruler limiter 6. The pressing of the rectangular push plate 14 enables the L-shaped clamping plate 13 to drive the rectangular sliding plate 15 to slide inside the depth positioning ruler limiter 6, so that the rectangular sliding plate 15 can slide outside the two transverse smooth rods 16. The sliding of the rectangular sliding plate 15 causes the transverse rigid spring 17 to contract under force. The movement of the L-shaped clamping plate 13 releases the restriction on the depth positioning ruler 5, so that the depth positioning ruler 5 can slide inside the depth positioning ruler limiter 6, so as to be able to adjust the sampling depth of the drilling.

[0037] Working principle: When using the powder sampling device of this technical solution, install the drill bit inside the drill chuck 7, slide the peripheral pipe 2 outside the drill chuck 7, and rotate the hexagonal rotating block 10. The rotation of the hexagonal rotating block 10, through the threaded connection of the threaded rod 11 and the circular cylinder 9, enables the circular limiting column 12 to move towards the drill chuck 7, and then enables the circular limiting column 12 to enter the inside of the circular groove, so as to be able to restrict the movement of the peripheral pipe 2 outside the drill chuck 7 and fix the peripheral pipe 2;

[0038] Then move the drill bit to the sampling location. When it is necessary to adjust the drilling sampling depth, press the rectangular push plate 14. The pressing of the rectangular push plate 14 enables the L-shaped clamping plate 13 to slide inside the depth positioning ruler limiter 6. The pressing of the rectangular push plate 14 enables the L-shaped clamping plate 13 to drive the rectangular sliding plate 15 to slide inside the depth positioning ruler limiter 6, so that the rectangular sliding plate 15 can slide outside the two transverse smooth rods 16. The sliding of the rectangular sliding plate 15 causes the transverse rigid spring 17 to contract under force. The movement of the L-shaped clamping plate 13 releases the restriction on the depth positioning ruler 5, so that the depth positioning ruler 5 can slide inside the depth positioning ruler limiter 6, so as to be able to adjust the sampling depth of the drilling, ensuring that samples at different depths can be obtained. The operation of the hand-held drill 1 enables the drill bit to rotate. The rotation of the drill bit enables the concrete to be crushed, so that the concrete powder can enter the inside of the powder sampling pipe 4, and the concrete can be directly sampled on-site without subsequent grinding treatment, so as to facilitate the determination of the chloride ion content and diffusion coefficient.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
