By setting the roller 12, the roller 12 is brought into contact with the concrete surface, so that the instrument body 1 can be moved on the concrete surface, and then with the action of the horizontal laser 15, the concrete structure can be scanned, so that the information of the steel bars can be obtained, and the minimum distance data between the concrete surface and the outermost steel bars can be obtained, so as to achieve the measurement of the protective layer;

[0023] A cleaning mechanism is provided on the surface of the measuring instrument body 1, and the cleaning mechanism includes a fixed plate 2, which is fixedly connected to the surface of the measuring instrument body 1, and a plug plate 21 is movably connected to the inner side of the fixed plate 2, and a brush 22 is fixedly connected to the surface of the plug plate 21, and a connecting block 23 is fixedly connected to the end of the plug plate 21 away from the brush 22, and a fixed block 24 is fixedly connected to the surface of the fixed plate 2, and a plug block 27 is movably connected to the inner side of the fixed block 24, and a slot 28 is provided on the inner side of the connecting block 23. By providing the slot 28, when the plug block 27 is inserted into the inner side of the slot 28, the connecting block 23 can be fixed, thereby ensuring the stability of the plug plate 21 in the fixed plate 2, and facilitating the brush 22 to stably contact the surface of the roller 12, thereby ensuring the cleaning effect.

[0024] Furthermore, the cleaning mechanism also includes a movable groove 25, which is opened on the inner side of the fixed block 24, and the inner wall of the movable groove 25 is fixedly connected with a spring 26, the plug block 27 and the movable groove 25 are movably connected, the surface of the plug block 27 is fixedly connected with a fixed rod 29, and the surface of the fixed rod 29 is fixedly connected with a connecting rod 210. Through the setting of the spring 26, the plug block 27 can be reset, and then the plug block 27 and the slot 28 can be inserted and engaged, thereby facilitating the fixation of the connecting block 23 and realizing the use of the brush 22.

[0025] Furthermore, the fixed plates 2 are formed into four groups and fixedly connected to the measuring instrument body 1, the plug plates 21 are formed into four groups and correspondingly connected to the fixed plates 2, and the plug blocks 27 are formed into two groups and movable on the inner side of the fixed blocks 24. Through the arrangement of the fixed plates 2 and the plug plates 21, it is convenient to install and fix the brush 22, thereby achieving the contact between the brush 22 and the surface of the roller 12, which can achieve the effect of cleaning the surface of the roller 12, thereby ensuring the cleanliness of the surface of the roller 12 and avoiding the roller 12 from getting stuck during rolling.

[0026] Furthermore, the plug block 27 is fixedly connected to the end of the spring 26 away from the movable groove 25, the fixing rod 29 is movable on the inner side of the movable groove 25, and the two sets of fixing rods 29 and the connecting rod 210 are correspondingly connected. Through the movement of the plug block 27 in the movable groove 25, the plug block 27 and the slot 28 can be plugged in and out, and then the connecting block 23 can be fixed and released, so that it is convenient to pull the plug plate 21 out of the fixed plate 2, and clean or replace the brush 22.

[0027] Furthermore, a supporting mechanism is provided on the surface of the measuring instrument body 1, and the supporting mechanism includes a connecting plate 3, which is fixedly connected to the surface of the measuring instrument body 1, and a screw 31 is movably connected to the surface of the connecting plate 3, and a movable rod 32 is threadedly connected to the surface of the screw 31, and a support rod 33 is fixedly connected to the surface of the movable rod 32. Through the rotation of the screw 31, the movable rod 32 can drive the support rod 33 to move vertically under the action of the screw 31, thereby facilitating the support rod 33 to descend to support the measuring instrument body 1, and the support rod 33 to rise so that the roller 12 can contact the concrete surface.

[0028] Furthermore, the two ends of the two groups of support rods 33 and the movable rods 32 are correspondingly connected, and the support rods 33 and the connecting plate 3 are movably connected. Through the setting of the support rods 33, the measuring instrument body 1 can be supported when no measurement is needed, thereby avoiding the contact between the roller 12 and the plane, thereby avoiding the movement of the measuring instrument body 1, which is beneficial to ensuring the stability of the measuring instrument body 1.

[0029] Working principle: when in use, the brush 22 contacts the surface of the roller 12. When the roller 12 rotates, friction is generated between the roller 12 and the brush 22, so that the brush 22 can clean the surface of the roller 12. When the brush 22 needs to be replaced or cleaned, by pulling down the connecting rod 210, the fixing rod 29 can move downward on the inner side of the movable groove 25 under the action of the connecting rod 210, and then the plug block 27 moves accordingly and separates from the slot 28. At this time, the spring 26 is in a contracted state, so that the fixing of the connecting block 23 is released, and then the plug plate 21 is pulled out from the fixing plate 2, so that the brush 22 can be cleaned or replaced. When the brush 22 needs to be installed and used, the plug plate 21 is inserted into the inner side of the fixing plate 2, and then the connecting rod 210 is loosened, and the plug block 27 is reset under the rebound action of the spring 26 and plugged into the slot 28, so that the connecting block 23 can be fixed, so that the brush 22 can be used.

[0030] By rotating the screw rod 31, since the support rod 33 is limited by the connecting plate 3, the movable rod 32 will move vertically under the action of the screw rod 31, thereby realizing the lifting and lowering movement of the support rod 33 on the inner side of the connecting plate 3. By descending the support rod 33, the support rod 33 can support the measuring instrument body 1, and then the roller 12 is suspended in the air, which can ensure the stability of the measuring instrument body 1 when it is placed. By ascending the support rod 33, the roller 12 can support the measuring instrument body 1, and then the roller 12 can contact the concrete surface during use, thereby performing measurement.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
