Description

Technical Field

[0001] This utility model belongs to the field of building maintenance technology, specifically relating to a crack detection device for building maintenance. Background Technology

[0002] Crack detection is a crucial step in home repair. Cracks in a house can be caused by a variety of factors, such as structural load, temperature changes, material shrinkage, and foundation settlement. If these cracks are not detected and treated in time, they will weaken the structural stability of the house, affect its service life, and even endanger the safety of residents. Appropriate detection equipment is required during inspection.

[0003] The patent specification with announcement number CN217083563U discloses a building maintenance and inspection device, including a vertical plate. Two vertical rods are inserted into the right side of the vertical plate. The two vertical rods are fixedly connected at one end on the right side of the vertical plate by a handle. A wheel frame is fixedly connected to one end of each of the two vertical rods at the left side of the vertical plate. Rolling wheels are installed inside the wheel frame. A liquid storage tank is fixedly connected to the left side of the vertical plate. Multiple rubber columns are fixedly connected to the left side of the liquid storage tank. This building repair and inspection device inserts two measuring fingers into wall cracks and then measures the width of the cracks according to the scale markings. Lime water is added to the inside of a storage tank and applied to the wall via a seepage strip, allowing subsequent repair personnel to quickly locate the cracks based on the markings. However, this technology has shortcomings. While the seepage rate of the indicator liquid remains relatively constant during wall inspection, the width of the cracks varies depending on the location. Maintaining a constant seepage rate can lead to missed markings when encountering wider cracks. Furthermore, it does not assist in estimating the amount of repair work required by subsequent repair personnel.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a crack detection device for house repair. The technical problem to be solved is as follows: When existing wall crack detection devices mark cracks, the marked area does not match the actual crack width.

[0006] The objective of this utility model can be achieved through the following technical solutions: A crack detection device for building repair includes a base plate, a displacement mechanism mounted on one side of the base plate, a marking box mounted on one side of the base plate, a liquid pushing component mounted between the marking box and the displacement mechanism, a liquid passage pipe mounted on one side of the bottom of the marking box, multiple casters mounted along the edge of the bottom surface of the base plate, a marking mechanism mounted in the middle of one side of the base plate, and a speed regulating mechanism provided between the marking mechanism and the displacement mechanism. The speed regulating mechanism is used to mark an appropriate amount of marking liquid according to the crack width detected by the marking mechanism.

[0007] As a further embodiment of this utility model: the displacement mechanism includes a drive motor fixedly connected to one side of the base plate, two rotating seats are installed at the output end of the drive motor, a screw is installed between the two rotating seats, the output end of the drive motor is fixedly connected to the end of the screw, a guide rail is fixedly connected to one side of the base plate in the direction parallel to the screw, a slider is slidably connected to the top of the guide rail, and one side of the liquid pushing component is fixedly connected to the top of the slider.

[0008] As a further embodiment of this utility model: the liquid pushing component includes a side plate fixedly connected to the top of the slider, one side of the bottom of the side plate is threadedly connected to the screw, a push rod is fixedly connected to one side of the side plate, the push rod extends into the inside of the marking box, and a liquid pushing plate is fixedly connected to the bottom end.

[0009] As a further embodiment of this utility model: the marking mechanism includes a clamping block fixedly connected to the base plate, one side of the clamping block being engaged with the liquid-passing pipe, a nozzle being installed at the end of the liquid-passing pipe, two positioning plates being fixedly connected to one side of the clamping block, two guide rods being fixedly connected between the two positioning plates, two detection plates being slidably connected between the two guide rods, and a spring being fixedly connected between the two detection plates to the guide rods.

[0010] As a further embodiment of this utility model: the speed regulating mechanism includes a microcontroller installed on one side of the clamping block, a linear potentiometer electrically connected to one side of the microcontroller, the lever of the linear potentiometer abutting against the detection plate on the adjacent side, the microcontroller electrically connected to a motor driver, and the motor driver electrically connected to the drive motor.

[0011] As a further embodiment of this utility model: a viewing window is provided on one side of the marking box, and a liquid filling cap is installed on the top side; a gripping rod is installed obliquely on one side of the bottom plate.

[0012] The beneficial effects of this utility model are: By installing a displacement mechanism and a liquid-pushing component on one side of the base plate, with the liquid-pushing component connected to the marking box, and a marking mechanism and a speed-regulating mechanism installed on the other side of the base plate, the two detection plates of the marking mechanism are inserted into the crack as the user moves the base plate. As the crack width changes, the detection plates are pushed outward by springs. The pressure exerted by the detection plates on the linear potentiometer is proportional to the crack width. The linear potentiometer converts the potential change through a microcontroller and a motor driver to control the speed of the drive motor. Thus, the speed at which the liquid-pushing component pushes the marking liquid is proportional to the crack width, thereby achieving the function of applying the appropriate amount of marking liquid to the crack width. The purpose is to correlate the speed of the drive motor with the crack detection width, so that subsequent repairers can intuitively grasp the distribution of cracks of different widths based on the application of the marking liquid, and to facilitate the estimation of the amount of repair material required.

Detailed Implementation

[0016] 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 scope of protection of the present utility model.

[0017] like Figures 1 to 4As shown, a crack detection device for house repair includes a base plate 1, a displacement mechanism 2 installed on one side of the base plate 1, a marking box 3 installed on one side of the base plate 1, a liquid pushing component 4 installed between the marking box 3 and the displacement mechanism 2, a liquid passage pipe 5 installed on one side of the bottom end of the marking box 3, four casters 6 installed along the edge of the bottom surface of the base plate 1, a marking mechanism 7 installed in the middle of one side of the base plate 1, and a speed regulating mechanism 8 set between the marking mechanism 7 and the displacement mechanism 2. The speed regulating mechanism 8 is used to mark an appropriate amount of marking liquid according to the crack width detected by the marking mechanism 7. It should be noted that the shifting mechanism 2 includes a drive motor 21 fixedly connected to one side of the base plate 1. Two rotating seats 22 are installed at the output end of the drive motor 21, and a screw 23 is installed between the two rotating seats 22. One end of the screw 23 is fixedly connected to the output end of the drive motor 21. A guide rail 24 is fixedly connected to one side of the base plate 1 in the direction parallel to the screw 23. A slider 25 is slidably connected to the top of the guide rail 24. A liquid pusher 4 is installed at the top of the slider 25. The liquid pusher 4 includes a side plate 41 fixedly connected to the top of the slider 25. One side of the bottom of the side plate 41 is threadedly connected to the screw 23. A push rod 42 is fixedly connected to one side of the side plate 41. The push rod 42 extends into the inside of the marking box 3 and is fixedly connected to the bottom end of a liquid pusher plate 43 (see...). Figure 2 That is, the drive motor 21 drives the screw 23 to rotate, which is limited by the guide rail 24, so that the side plate 41 installed at the top of the slider 25 can move vertically, thereby pushing the liquid pusher 43 to push the marking liquid into the liquid pipe 5, and finally the marking mechanism 7 marks it on the wall of the building to be repaired.

[0018] A viewing window 9 is provided on one side of the labeling box 3 to observe the amount of labeling liquid inside, and a filling cap 10 is installed on the top side to determine whether the labeling liquid needs to be added based on the amount. An angled gripping rod 11 is installed on one side of the base plate 1 to facilitate pushing the base plate 1 to move.

[0019] like Figure 3 and Figure 4 As shown, the marking mechanism 7 includes a clamping block 71 fixedly connected to the base plate 1. One side of the clamping block 71 is engaged with the liquid pipe 5. A nozzle 72 is installed at the end of the liquid pipe 5. Two positioning plates 73 are fixedly connected to one side of the clamping block 71. Two guide rods 74 are fixedly connected between the two positioning plates 73. Two detection plates 75 are slidably connected between the two guide rods 74. A spring 76 is fixedly connected between the two detection plates 75 and the guide rods 74. The speed control mechanism 8 includes a microcontroller 81 mounted on one side of the clamp 71. A linear potentiometer 82 is electrically connected to one side of the microcontroller 81. The lever of the linear potentiometer 82 abuts against the detection plate 75 on the adjacent side. The microcontroller 81 is electrically connected to a motor driver 83. The motor driver 83 is electrically connected to the drive motor 21. It should be noted that during wall crack detection, two detection plates 75 are inserted into the crack. Because the spring 76 between the two detection plates 75 is compressed, and the detection plates 75 are held in place by the crack, the width between the two detection plates 75 adapts to the crack width as the base plate 1 moves. When the crack is large, the pressure rod of the linear potentiometer 82 experiences greater compression and extension, resulting in a larger potential difference. This voltage difference information is transmitted to the microcontroller 81, which converts the voltage information into PWM digital control. The signal is sent to the motor driver 83, which then provides the corresponding voltage and current to control the rotation of the drive motor 21. The rotation speed of the drive motor 21 controls the displacement speed of the liquid pusher 4. That is, when the crack is wide, the pushing speed of the liquid pusher 43 is fast, and the amount of liquid sprayed by the nozzle 72 increases, so as to fully cover the crack with the marking liquid. When the crack is narrow, the pushing speed of the liquid pusher 43 is slow, and the amount of liquid sprayed by the nozzle 72 is reduced, so as to cover the narrow crack with a smaller amount of liquid. This realizes the function of spraying the marking liquid appropriately according to the change of crack width.

[0020] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
