Description

Technical Field

[0001] This application relates to the field of concrete crack detection technology, specifically a concrete crack detection device. Background Technology

[0002] Concrete crack detection is a crucial step in assessing the health and safety of concrete structures. It involves the discovery, measurement, analysis, and possible repair measures for cracks in concrete.

[0003] An existing patent (publication number: CN 215524511U) discloses a concrete crack detection device, including a movable platform for fixing a camera and a main unit adapted to the camera. The main unit is independently set up and connected to the camera for data transmission. The movable platform is equipped with a rolling component to facilitate movement on the surface of the concrete structure. This invention, by fixing the camera to a movable platform, allows the platform to move smoothly on the outer surface of the concrete structure via the rolling component. The movable platform maintains contact with the concrete structure surface throughout its movement. When crack width needs to be measured, the platform can be directly moved to the desired crack location for measurement, greatly increasing the convenience of crack width measurement, reducing the labor intensity of operators, and improving concrete detection efficiency.

[0004] The camera of the aforementioned concrete crack detection device is not easy to disassemble, maintain, and use, which reduces the flexibility and practicality of the detection device. Furthermore, during the detection process, sand and other debris in the concrete cracks can affect the detection results. Since the concrete cracks are small, manual cleaning of the cracks not only increases the workload of workers but is also quite laborious. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a concrete crack detection device that facilitates the disassembly, maintenance, and use of the camera, improving the flexibility and practicality of the detection device. It also facilitates the cleaning of sand and other debris from concrete cracks, ensuring the accuracy of detection results, reducing the cleaning burden on workers, and improving detection efficiency. This solves the problems of existing concrete crack detection devices where the camera is inconvenient to disassemble, maintain, and use, reducing the flexibility and practicality of the detection device. Furthermore, during the detection process, sand and other debris in the concrete cracks can affect the detection results. Since concrete cracks are small, manual cleaning of the cracks not only increases the workload for workers but is also quite laborious.

[0006] To achieve the above objectives, this application provides the following technical solution: a concrete crack detection device, comprising a base plate, a mounting base fixedly connected inside the base plate, a camera slidably inserted inside the mounting base, two lead screws rotatably inserted inside the mounting base, a positioning rod threaded onto the outer circumference of each lead screw, two positioning holes inside the camera, and the positioning rods slidably inserted into the camera through the positioning holes, a base fixedly connected to one end of the base plate, a spray pipe slidably inserted inside the base, a nozzle at the bottom of the spray pipe, an air pump on the upper surface of the base plate, a connecting pipe fixedly connected to the top of the air pump, the other end of the connecting pipe being fixedly connected to the top of the spray pipe, four rollers at the bottom of the base plate, and a handle fixedly connected to the upper surface of the base plate.

[0007] The above solution addresses the limitations of existing concrete crack detection devices. The cameras in these devices are difficult to disassemble, maintain, and use, reducing the device's flexibility and practicality. Furthermore, sand and other debris in the concrete cracks can affect the detection results. Since the cracks are small, manual cleaning not only increases the workload for workers but is also laborious. By rotating the screw to move the positioning rod into or out of the positioning hole, the camera can be easily installed and disassembled, facilitating maintenance and use. This improves the device's flexibility and practicality. The inclusion of an air pump, connecting pipe, spray pipe, and nozzle facilitates the cleaning of sand and debris from the concrete cracks, ensuring accurate results, reducing the cleaning burden on workers, and increasing detection efficiency.

[0008] Furthermore, two auxiliary plates are fixedly connected to the outer circumference of the camera, and the outer surface of the auxiliary plates is slidably connected to the mounting base through a slot opened in the inner wall of the mounting base.

[0009] The above solution allows the auxiliary plate to assist in the installation of the camera, ensuring that the positioning rod and positioning hole are aligned, facilitating camera installation. It also restricts the camera, preventing it from rotating and improving its stability.

[0010] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each lead screw, and the outer circumferential surface of the limiting ring is rotatably connected to the interior of the mounting base.

[0011] The above method restricts the lead screw, preventing it from slipping and deviating, and improving the stability of the lead screw's movement.

[0012] Furthermore, a limiting block is fixedly connected to the outer circumferential surface of each positioning rod, and the outer surface of the limiting block is slidably connected to the mounting base through a slot opened inside the mounting base.

[0013] The above solution restricts the positioning rod, preventing it from rotating with the lead screw and ensuring that the positioning rod always moves laterally. It also prevents the positioning rod from easily falling out of the mounting base.

[0014] Furthermore, the bottom of the mounting base is provided with equally spaced lighting lamps.

[0015] The above solution enables the lighting to illuminate the camera, resulting in clearer images.

[0016] Furthermore, the bottom surface of the base plate is fixedly connected to two slide rails, and the two slide rails are slidably connected to a baffle through an internal groove.

[0017] With the above solution, when not shooting, the baffle can be moved below the camera to protect it and prevent it from being easily damaged.

[0018] Furthermore, the nozzle is tilted at a certain angle, and the connecting pipe is a flexible pipe.

[0019] The above solution allows the nozzle, when tilted at a certain angle, to better blow sand or debris out of concrete cracks, while the flexible connecting pipe allows the nozzle to move up and down.

[0020] Furthermore, an electric telescopic rod is fixedly connected to the top of the base, and the output end of the electric telescopic rod is fixedly connected to the top of the nozzle.

[0021] The above solution uses an electric telescopic rod to raise and lower the nozzle, which facilitates the cleaning of sand or debris from concrete cracks and avoids damage to the nozzle or nozzle caused by moving it too low.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This concrete crack detection device uses a rotating screw to move a positioning rod into or out of a positioning hole, facilitating the installation and removal of the camera. This, in turn, facilitates camera maintenance and use, improving the flexibility and practicality of the detection device. The inclusion of an air pump, connecting pipe, spray pipe, and nozzle allows for easy cleaning of sand or debris from concrete cracks, ensuring accurate detection results, reducing the cleaning burden on workers, and increasing detection efficiency. This device solves the problems of existing concrete crack detection devices where the camera position is fixed, making disassembly, maintenance, and use inconvenient, resulting in low flexibility and practicality, and the inaccuracy of detection results due to sand or debris in the cracks.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of a concrete crack detection device includes a base plate 1, a mounting base 2 fixedly connected inside the base plate 1, a camera 3 slidably inserted inside the mounting base 2, two lead screws 4 rotatably inserted inside the mounting base 2, and a positioning rod 5 threadedly connected to the outer circumference of each lead screw 4. Two positioning holes 6 are opened inside the camera 3, and the positioning rods 5 are slidably inserted into the camera 3 through the positioning holes 6. A base 13 is fixedly connected to one end of the base plate 1, and a spray pipe 15 is slidably inserted inside the base 13. A nozzle 16 is provided at the bottom of the spray pipe 15. An air pump 17 is provided on the upper surface of the base plate 1, and a connecting pipe 18 is fixedly connected to the top of the air pump 17. The other end of the connecting pipe 18 is fixedly connected to the top of the spray pipe 15. Four rollers 19 are provided at the bottom of the base plate 1, and a handle 20 is fixedly connected to the upper surface of the base plate 1.

[0032] Please see Figure 1 , Figure 3 and Figure 4Two auxiliary plates 7 are fixedly connected to the outer circumference of the camera 3. The outer surface of the auxiliary plates 7 is slidably connected to the mounting base 2 through the slots opened in the inner wall of the mounting base 2. The auxiliary plates 7 can assist the camera 3 in installation, so that the positions of the positioning rod 5 and the positioning hole 6 correspond, making it easier to install the camera 3. At the same time, they can also restrict the camera 3 to prevent it from rotating and improve the stability of the camera 3.

[0033] Please see Figure 4 Each lead screw 4 has a limit ring 8 fixedly sleeved on its outer circumference. The outer circumference of the limit ring 8 is rotatably connected to the inside of the mounting base 2 to restrict the lead screw 4, prevent the lead screw 4 from sliding and deviating, and improve the stability of the lead screw 4's movement.

[0034] Please see Figure 4 Each positioning rod 5 is fixedly connected to a limiting block 9 on its outer circumference. The outer surface of the limiting block 9 is slidably connected to the mounting base 2 through a slot opened inside the mounting base 2, which restricts the positioning rod 5 and prevents the positioning rod 5 from rotating with the lead screw 4, so that the positioning rod 5 always moves laterally, and also prevents the positioning rod 5 from easily falling out of the mounting base 2.

[0035] Please see Figure 2 The bottom of the mounting base 2 is provided with equally spaced lighting lamps 10, which can provide illumination for the camera 3, making the camera 3 capture clearer images.

[0036] Please see Figure 2 The bottom surface of the base plate 1 is fixedly connected to two slide rails 11. The two slide rails 11 are slidably connected to a baffle 12 through an internal groove. When not shooting, the baffle 12 can be moved to the bottom of the camera 3 to protect the camera 3 and prevent it from being easily damaged.

[0037] Please see Figure 1 and Figure 3 The nozzle 15 is tilted at a certain angle, and the connecting pipe 18 is a flexible pipe. The nozzle 15 tilted at a certain angle can better blow out sand or debris from the cracks in the concrete. The flexible connecting pipe 18 can meet the needs of the nozzle 15 to move up and down.

[0038] Please see Figure 1 , Figure 2 and Figure 3 An electric telescopic rod 14 is fixedly connected to the top of the base 13. The output end of the electric telescopic rod 14 is fixedly connected to the top of the nozzle 15. The nozzle 15 is raised and lowered by the electric telescopic rod 14, which facilitates the cleaning of sand or debris in concrete cracks and also prevents the nozzle 15 from being too low during movement, which could damage the nozzle 15 or the nozzle 16.

[0039] In this embodiment, a concrete crack detection device uses a rotating screw 4 to move a positioning rod 5 into or out of a positioning hole 6, facilitating the installation and removal of a camera 3. This, in turn, facilitates the maintenance and use of the camera 3, improving the flexibility and practicality of the detection device. The inclusion of an air pump 17, connecting pipe 18, spray pipe 15, and nozzle 16 facilitates the cleaning of sand or debris from concrete cracks, ensuring the accuracy of the detection results, reducing the cleaning burden on workers, and improving detection efficiency. This solves the problems of existing concrete crack detection devices where the camera 3 is fixed in position, making disassembly, maintenance, and use inconvenient, resulting in low flexibility and practicality, and the sand or debris in the cracks affecting the accuracy of the detection results.

[0040] It should be noted that a handwheel is provided on the outer circumference of the lead screw 4, which can be used to control the lead screw 4.

[0041] The working principle of the above embodiments is as follows:

[0042] When concrete crack detection is required, the detection device is moved to one side of the crack by pushing the handle 20 and roller 19. If there is sand or debris in the crack, the electric telescopic rod 14 is activated to move the nozzle 15 and nozzle 16 downward, causing the nozzle 16 to tilt and aim at one end of the crack. Then, the air pump 17 is activated to spray air through the connecting pipe 18. The high-pressure gas will be sprayed to the outside through the nozzle 15 and nozzle 16 to blow out the debris from the crack and clean it. After cleaning, the camera 3 is moved above the crack, and the lighting 10 is turned on for illumination. The crack can then be photographed and detected. When the camera 3 needs to be disassembled for maintenance or use, the screw 4 is rotated to move the positioning rod 5 out of the positioning hole 6, removing the positioning restriction of the positioning rod 5 on the camera 3. The camera 3 can then be taken out of the mounting base 2. When the camera 3 needs to be installed, the camera 3 is inserted into the mounting base 2, and the screw 4 is rotated in the opposite direction to move the positioning rod 5 back, causing the positioning rod 5 to insert into the positioning hole 6.
