Description

Technical Field

[0001] This utility model relates to the field of detection devices, and in particular to a bridge crack detection device. Background Technology

[0002] Bridge crack detection is crucial for ensuring bridge safety and extending its service life. Early detection of cracks helps in taking repair measures and preventing cracks from expanding or causing serious damage. Bridge crack detection devices are mainly used to identify and monitor cracks in bridge structures to ensure safety and maintenance efficiency.

[0003] A search revealed Chinese Patent Publication No. CN221017542U, which discloses a bridge underside crack detection device. The device includes a main unit, a detector, and a transmission signal line connecting the main unit and the detector. The detector's front end is connected to a detection head for identifying crack depth and width via a mounting housing. The device also includes a cleaning component mounted on the mounting housing for cleaning the surface of the detection head. This cleaning component includes a mounting plate slidably connected to the mounting housing and a rubber scraper elastically connected to the mounting plate via a pressing component. During use, the crack width tester in this bridge underside crack detection device works by cooperating with the cleaning component, pressing component, and pushing component to move the rubber scraper. The movement of the rubber scraper cleans the surface of the detection head, automatically cleaning it before detection and ensuring the cleanliness of the detection head surface during the detection process, thus improving the detection accuracy of bridge underside cracks.

[0004] Although the aforementioned device can clean the surface of the detection head by setting a rubber scraper, some sand particles and other impurities may adhere to the surface of the detection head during the detection process. Direct scraping can easily scratch the detection head. Moreover, relying solely on a silicone scraper that is prone to deformation cannot guarantee that the impurities can be effectively removed, nor can the cleaning effect be guaranteed. Therefore, it is not practical enough. To address these issues, a bridge crack detection device is proposed. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a bridge crack detection device, including a detection device 1, which can be a crack width tester or other detection instrument. The front of the detection device 1 is provided with a detection head 2, which is used to detect bridge cracks. The front of the detection head 2 is provided with a cleaning and protection mechanism 3, which is used to clean and protect the detection head 2. The cleaning and protection mechanism 3 includes a shell 31, which is used to connect various components. The upper, lower, left, and right sides of the shell 31 are provided with auxiliary openings 32, which are used to facilitate the discharge of particulate impurities during cleaning and also to facilitate the installation of a protective plate 33. A cleaning component 35 is provided in the middle of the shell 31. The upper, lower, left, and right sides of the rear side of the shell 31 are fixedly connected with clamping plates 34, which are used to fix the shell 31 and the detection head 2. The middle of the shell 31 is provided with a protective plate 33, which is used to protect the detection head 2.

[0033] like Figures 3-5 As shown, the cleaning component 35 includes a pull rod 351, which is used to connect various components. The pull rod 351 is slidably connected to the housing 31. A cavity 352 is provided in the middle of the housing 31, which is used to facilitate the flow of gas when the piston plate 353 moves. The piston plate 353 is fixedly connected to the front end of the pull rod 351. The piston plate 353 can be made of rubber or other materials. A support plate is provided in the middle to prevent it from deforming too much. The piston plate 353 is connected to the cavity 352 to facilitate the blowing of gas. An air outlet pipe 354 is slidably connected to the middle of the housing 31, which is used to facilitate the effective blowing of gas towards the protective plate 25 of the detection head 2 and to clean sand and gravel particles on its surface.

[0034] Furthermore, the inner walls of the auxiliary ports 32 located on the left and right sides are provided with connection ports 321 on both the upper and lower parts, which are used to connect with the protective plate 33. The protective plate 33 is movably connected to the connection port 321. The inner side of the clamping plate 34 is provided with a limiting groove 341, which is movably connected with the limiting strip 22. The clamping plate 34 can produce a small deformation. The left and right sides of the protective plate 33 are fixedly connected with positioning plates 331, whose width is adapted to the auxiliary ports 32. They are used to limit the distance between the protective plate 33 and the detection head 2. The rear side of the positioning plate 331 is fixedly connected with a rubber sheet 332, which is slightly narrower than the positioning plate 331. It is used to cooperate with the flexible positioning of the protective plate 33 during installation to achieve preliminary limiting. It can produce a certain degree of deformation.

[0035] Furthermore, the outer wall of the detection head 2 is provided with limiting components 21 on the top, bottom, left, and right sides, which are used to limit the movement of the clamping plate 34. The limiting component 21 includes two limiting plates 211, and the distance between the two limiting plates 211 is adapted to the width of the clamping plate 34. The limiting plates 211 are fixedly connected to the outer wall of the detection head 2. Two limiting strips 22 are provided between the two limiting plates 211, and the two limiting strips 22 are arranged front and back. When the clamping plate 34 is only engaged with the front limiting strip 22, the distance between the connection port 321 and the detection head 2 allows the protective plate 33 and the positioning plate 331 to pass smoothly, but it will slightly obstruct the rubber sheet 332, thus making the installation of the protective plate 33 more difficult. When the rubber sheet 332 can generate a certain degree of flexible positioning, it can ensure that the protective plate 33 can be smoothly limited. When the clamping plate 34 and the two limiting strips 22 are clamped together, the connection port 321 can make the protective plate 33 abut against the surface of the detection head 2, thereby protecting the detection head 2. The two limiting strips 22 are fixedly connected to the outer wall of the detection head 2. The limiting groove 341 is clamped to the limiting strip 22. The front part of the detection head 2 is provided with an installation groove 23, which is used to connect various components. The middle part of the installation groove 23 is equipped with a camera 24, and lighting and other components are arranged around it. It is used to detect bridge cracks. The front part of the inner wall of the installation groove 23 is fixedly connected with a protective plate 25, which can be made of transparent materials such as glass.

[0036] Working principle: In use, the outer shell 31 is first fixed to the detection head 2 by multiple clamping plates 34. At this time, the clamping plates 34 will be clamped between the two limiting plates 211 and the front limiting strip 22. Then, the pull rod 351 can be pushed, which will drive the piston plate 353 fixed thereto to move, thereby blowing the gas in the cavity 352 through the air outlet pipe 354 onto the surface of the detection head 2, thereby cleaning the sand particles and other impurities on its surface. Then, the pull rod 351 is pulled in the opposite direction to allow new gas to enter the cavity 352. The pull rod 351 is pushed again to blow the gas onto the detection head 2. This process is repeated multiple times until the surface of the detection head 2 is clean.

[0037] Then, insert the protective plate 33 into the connection port 321. At this time, the rubber sheet 332 will deform to a certain extent, allowing it to pass smoothly through the surface of the detection head 2. The two rubber sheets 332 can be locked on the left and right sides of the detection head 2, thus initially positioning the protective plate 33. Then, press the outer shell 31 again to lock the clamping plate 34 and the two limiting strips 22 together. At this time, the outer shell 31 will drive the protective plate 33 to press against the front of the detection head 2 through the connection port 321, thereby locking the positioning plate 331 on both sides of the detection head 2 and fixing the position of the protective plate 33. This allows the positioning plate 331 to protect the detection head 2. If the detection head 2 needs to be used, simply pull the outer shell 31 to separate the clamping plate 34 from the detection head 2, thus disengaging the cleaning and protection mechanism 3 from the detection head 2.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
