[0001] The utility model relates to building detection instrument technical field, concretely is a wall body hidden crack detection device for building detection. BACKGROUND

[0002] In the field of building safety detection, wall body hidden crack refers to that there is no obvious crack on the surface of the wall body, but there may be tiny cracks or damage inside or below the wall surface. Such cracks are often not easy to be detected by naked eyes, but if not handled in time, they may lead to structural problems or further damage.

[0003] In the traditional way, artificial knocking detection method relies on the experience of operators, which judges internal defects by hammering the wall surface and listening to sound changes, but has strong subjectivity, low efficiency, and easy to miss tiny hidden cracks. UTILITY MODEL CONTENT

[0004] In view of the deficiency of prior art, the utility model provides a wall body hidden crack detection device for building detection, which has the advantages of high efficiency and accuracy in detecting the position of wall body hidden crack, and reduces the missed detection phenomenon. The problem of strong subjectivity, low efficiency and accuracy, and more missed detection in the way of detecting wall body hidden crack by artificial knocking wall body and using sound to determine position at the present stage is solved.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a wall body hidden crack detection device for building detection, which comprises a detection piece and a knocking piece. The detection piece comprises a protective cover, a ring-shaped disc is fixed to the edge of the protective cover, a plurality of mounting holes are equally arranged on the ring-shaped disc, a vibration sensor is installed in each mounting hole, the ring-shaped disc is made of hard silica gel material and has a certain wear resistance, a plurality of mounting holes are equally arranged on the ring-shaped disc, a vibration sensor is installed in each mounting hole by screw connection, the vibration sensor is connected to an external data terminal, so as to realize the effect of collecting and detecting vibration wavelengths in multiple directions and feeding back to the terminal. Through the terminal, the wavelength values of the vibration sensors with small wavelength values and the adjacent vibration sensors can be understood, and the values of the adjacent vibration sensors gradually increase, so that the position of the wall body hidden crack can be quickly located in time.

[0006] The center of the protective cover is provided with a ring-shaped interface, the diameter of the ring-shaped interface matches the diameter of the front end of the sleeve, and when the ring-shaped interface and the front end of the sleeve are closed, the movable rod can be stably displaced in the ring-shaped interface.

[0007] The knocking piece is movably connected to the rear side of the protective cover, the knocking piece comprises a sleeve movably connected to one end of the ring-shaped interface, a movable rod is movably sleeved in the sleeve, a knocking ball is fixed to the front end of the movable rod, and the movable rod moves forward and backward in the sleeve, so that the front end knocking ball repeatedly knocks the wall body to generate vibration wavelengths.

[0008] The bottom of the sleeve is equipped with an installation cylinder, inside which an electric telescopic rod is fixed. A connecting rod is fixed at the output end of the electric telescopic rod. A connecting plate is movably connected to one end of the connecting rod, and one end of the connecting plate is movably connected to the tail end of the moving rod. When the electric telescopic rod operates, its output end drives the connecting rod to reciprocate telescopic motion, and through the connecting plate drives the moving rod to reciprocate back and forth motion, causing the striking ball at the front end of the moving rod to repeatedly strike the wall, causing the wall to vibrate.

Then, activate the electric telescopic rod, which drives the connecting rod to move back and forth. The connecting plate then moves the moving rod back and forth within the sleeve. By continuously striking the wall surface with a striking ball, vibration wavelengths are generated. The location of the crack will cause the wavelength to break or the wavelength value to be lower. The vibration sensor detects the wavelength and calculates the value, which is then fed back to the connected back-end terminal. By locating adjacent vibration sensors with lower and gradually increasing wavelength values, the problem of cracks in the wall can be detected.

[0018] Through the technical scheme, the diameter of the limiting rod matches the diameter in the limiting slot, the stability of the displacement of the moving rod is improved, and the phenomenon of rotation of the moving rod during forward and backward movement is avoided, so that the stability of the ball hitting the wall surface is ensured.

[0036] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. Embodiment one

[0037] Please refer to Figures 1-5As shown, the wall hidden crack detection device for building detection provided in the embodiment comprises a detection piece 1 and a knocking piece 2. The detection piece 1 comprises a protective cover 101, a ring-shaped disc 102 is fixed at the edge of the protective cover 101, a plurality of mounting holes 103 are equidistantly arranged on the ring-shaped disc 102, a vibration sensor 104 is mounted in each mounting hole 103, the ring-shaped disc 102 is made of hard silica gel material and has a certain wear resistance, a plurality of mounting holes 103 are equidistantly arranged on the ring-shaped disc 102, the vibration sensor 104 is mounted in each mounting hole 103 by means of threaded connection, the vibration sensor 104 is connected to an external data terminal, so as to realize the effect of collecting and detecting vibration wavelengths in multiple directions and feeding back to the terminal. The wavelength values of the vibration sensor 104 with small wavelength values and the adjacent vibration sensors 104 can be understood through the terminal, and the wavelength values of the adjacent vibration sensors 104 gradually increase, so that the position of the wall hidden crack can be quickly located in time.

[0038] Meanwhile, the protective cover 101 can control the vibration wavelength within the covered range, thereby improving the detection accuracy of the vibration sensor 104.

[0039] It should be further explained that the number and spacing of the vibration sensors 104 are designed according to the diameter of the actually used ring-shaped disc 102. The spacing between the adjacent vibration sensors 104 is 4-7 cm, so as to ensure the stability of the wavelength detection.

[0040] The center position of the protective cover 101 is provided with a ring-shaped interface 105, the diameter of the ring-shaped interface 105 is consistent with the diameter of the front end of the sleeve 201, when the ring-shaped interface 105 is closed with the front end of the sleeve 201, the movable rod 202 can be stably extended and retracted in the ring-shaped interface 105.

[0041] The knocking piece 2 is movably connected to the rear side of the protective cover 101. The knocking piece 2 comprises a sleeve 201 movably connected to one end of the ring-shaped interface 105. The movable rod 202 is movably sleeved in the sleeve 201. The knocking ball 203 is fixed at the front end of the movable rod 202. The movable rod 202 moves forward and backward in the sleeve 201, so that the front-end knocking ball 203 repeatedly knocks the wall and generates vibration wavelengths.

[0042] It should be further explained that the knocking ball 203 is made of metal material. When the wall surface is knocked, the knocking ball 203 generates a circular wavelength diverging outward.

[0043] The bottom of the sleeve 201 is provided with a mounting cylinder 204, and a motor-driven telescopic rod 205 is fixed in the mounting cylinder 204. The output end of the motor-driven telescopic rod 205 is fixed with a connecting rod 206. The one end of the connecting rod 206 is movably connected with a connecting plate 207. The tail end of the connecting plate 207 is movably connected with the tail end of the moving rod 202. When the motor-driven telescopic rod 205 operates, the output end drives the connecting rod 206 to reciprocatingly stretch and retract, and drives the moving rod 202 to reciprocatingly move forward and backward through the connecting plate 207, so that the knocking ball 203 at the front end of the moving rod 202 repeatedly knocks the wall surface, and the wall surface is vibrated.

[0044] When the wall hidden crack detection device for building detection is used, the device is held by the hand knob 213, the protective cover 101 is aligned with the wall, and the vibration sensor 104 is ensured to be attached to the wall surface. At this time, the motor-driven telescopic rod 205 is started to operate, the output end drives the connecting rod 206 to reciprocatingly move forward and backward, and the moving rod 202 is driven to move forward and backward in the sleeve 201 through the connecting plate 207. The knocking ball 203 constantly knocks the wall surface to generate vibration wavelength, so that the hidden crack position causes the wavelength to be disconnected or the wavelength value to be small. The wavelength is detected by the vibration sensor 104 and the value is calculated, and the value is fed back to the connected background terminal. The adjacent vibration sensors with small wavelength values and gradually increasing wavelength values can detect the hidden crack problem of the wall.

[0045] The rear side of the protective cover 101 is provided with a mounting rod 106, and the mounting rod 106 is rotatably connected with a threaded rod 107 at one end.

[0048] Further, the connecting rod 206 is composed of a supporting rod 2061 and a connecting knob 2062. One end of the supporting rod 2061 is fixed on the connecting knob 2062, and the other end is fixed on the output end of the motor-driven telescopic rod 205. The tail end of the moving rod 202 is fixed with a sleeve knob 2021, and the sleeve knob 2021 and the connecting knob 2062 are movably sleeved in the connecting plate 207.

[0049] More specifically, the connecting rod 206 is connected with the connecting plate 207 through the connecting knob 2062, and the moving rod 202 is connected with the connecting plate 207 through the sleeve knob 2021, so that when the connecting rod 206 moves, the moving rod 202 is driven to move through the connecting plate 207.

[0050] It needs to be further explained that the two ends of the linkage plate 207 are provided with round holes, and the diameters of the connecting button 2062 and the sleeve button 2021 are consistent with the diameters of the round holes, which are sleeved in the round holes.

[0051] Further, the side of the linkage plate 207 movably sleeves two bolt rods 208, and the two bolt rods 208 respectively penetrate the sleeve button 2021 and the connecting button 2062.

[0052] More specifically, the two bolt rods 208 penetrate the corresponding round holes and the sleeve button 2021 and the connecting button 2062 sleeved in the round holes from the sides of the two ends of the linkage plate 207, thereby realizing the fixing effect of the linkage plate 207 and the linkage rod 206 and the moving rod 202, and facilitating the later disassembly, maintenance and replacement.

[0053] Further, the side of the moving rod 202 is provided with a limiting sliding groove 210 along the length direction, and the sleeve 201 is threadedly connected with a limiting rod 209, one end of the limiting rod 209 being slidably connected in the limiting sliding groove 210.
