Description

Technical Field

[0001] This utility model relates to the field of tunnel inspection technology, specifically a tunnel crack detection device. Background Technology

[0002] A tunnel is a man-made passage dug underground or in a mountain. It is mainly used for transportation, water transport, mining, etc. It can shorten the travel distance and avoid complex terrain obstacles. Its structure usually consists of lining, support, waterproofing, ventilation and other systems. It needs to be designed and constructed according to geological conditions, and has the functions of ensuring traffic safety and resisting stratum pressure and groundwater erosion.

[0003] Tunnel inspection is a comprehensive investigation of the structural safety and operational status of tunnels. It covers structural defects, equipment functions, environmental safety and other dimensions. Crack detection is usually carried out through manual inspection, vehicle-mounted inspection equipment or drones, and uses visual observation, sound wave detection or image recognition technology to capture crack information.

[0004] Existing tunnel inspections are conducted using vehicle-mounted visual observation equipment and marking pens. However, the marking pen needs to contact the marking surface to make a mark, and the marking effect will be affected when the marking pen encounters an uneven contact surface.

[0005] Therefore, a tunnel crack detection device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

At the same time, the paint is a biodegradable paint that will self-eliminate, thereby reducing long-term damage to the tunnel.

[0008] Preferably, a servo motor is fixedly connected to the inner wall of the detection component; a support plate is fixedly connected to the output end of the servo motor; the support plate is through-mounted and rotatably connected to the detection component; a square plate is fixedly connected to the end of the support plate; when detecting a tunnel, if wind affects the coating, the servo motor can be activated to drive the support plate to rotate. When the support plate rotates, it will drive the square plate to rotate, and then the square plate will move in front of the nozzle, thereby blocking the wind in front; by adding the square plate, when wind affects the coating, the wind can be intercepted by the square plate, thereby reducing the impact of wind when the nozzle sprays the coating, thus increasing the effect of the nozzle spraying the coating.

[0009] Preferably, a support pipe is fixedly connected to the end of the inspection vehicle; a wind direction cloth is fixedly connected to the end of the support pipe; when wind occurs, it will cause the wind direction cloth to swing, and the wind force can be observed by observing the swing amplitude of the wind direction cloth, thereby allowing for faster movement of the square plate; by adding a wind direction cloth, the impact of wind force can be quickly judged by the swing of the wind direction cloth when wind occurs, thereby increasing the reference for wind force and making inspection more convenient.

[0010] Preferably, a baffle is fixed to the top of the inspection vehicle; the baffle is located between the wide-angle camera and the wind direction cloth and is inclined; when the paint is sprayed, the inspection vehicle is in a moving state, and some paint will approach the inspection vehicle. At this time, the baffle will block these paints; by adding a baffle, the spilled paint can be intercepted, thereby reducing the contact between the paint and the inspection components.

[0011] Preferably, a lighting lamp is fixedly connected to the end of the inspection vehicle; multiple lighting lamps are installed on the inspection vehicle; by adding lighting lamps, the observation environment of the wide-angle camera can be supplemented, thereby increasing the convenience of observing cracks in the tunnel and increasing the ambient light.

[0012] Preferably, a pair of guide plates are fixed to the end of the square plate; the guide plates are symmetrically arranged on the square plate; by adding guide plates, the wind force received by the square plate can be guided, thereby reducing the resistance during movement and increasing the smoothness of movement.

[0013] The advantages of this utility model are: 1.

[0018] 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.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5As shown in the figure, a tunnel crack detection device according to an embodiment of the present invention includes a detection vehicle 1, a detection component 11 fixedly connected to the top of the detection vehicle 1; a drive component 12 provided on the inner wall of the detection component 11; a material hopper 18 fixedly connected to the middle of the detection component 11; an inlet pipe 13 opened at the top of the material hopper 18; a conveying pump 14 connected to the side wall of the material hopper 18; a transmission pipe 15 connected to the end of the conveying pump 14; a nozzle 16 connected to the end of the transmission pipe 15; the transmission pipe 15 is through the detection component 11; a wide-angle camera 17 is provided at the end of the detection component 11; in operation, the detection vehicle 1 is first placed on the ground, and then the drive component 12 drives the wheels to move into the tunnel, while the wide-angle camera 17 is simultaneously moved into the tunnel. The system connects to the display screen, transmitting the ground image captured by the wide-angle camera 17 to the screen. When a crack appears in the image, the drive component 12 starts the delivery pump 14. When the delivery pump 14 starts, it draws biodegradable paint from the hopper 18, which then enters the transmission pipe 15 and is sprayed out through the nozzle 16. After spraying, the crack is marked, thus quickly marking the crack with paint. After marking, the system continues to move forward, marking subsequent cracks in sequence. By using paint to mark cracks, the visual effect of cracks can be improved during marking, thereby speeding up the search for cracks when they are subsequently treated. At the same time, the paint is biodegradable and will be self-eliminating in the future, thereby reducing long-term damage to the tunnel.

[0021] like Figures 1 to 5 As shown, a servo motor 2 is fixedly connected to the inner wall of the detection component 11; a support plate 21 is fixedly connected to the output end of the servo motor 2; the support plate 21 is through-mounted and rotatably connected to the detection component 11; a square plate 22 is fixedly connected to the end of the support plate 21; during operation, when detecting a tunnel, if wind affects the coating, the servo motor 2 can be activated to drive the support plate 21 to rotate. When the support plate 21 rotates, it will drive the square plate 22 to rotate, and then the square plate 22 will move in front of the nozzle 16, thereby blocking the wind in front; by adding the square plate 22, when wind affects the coating, the wind can be blocked by the square plate 22, thereby reducing the impact of wind when the nozzle 16 sprays the coating, thus increasing the effect of the nozzle 16 spraying the coating.

[0022] like Figures 2 to 4 As shown, a support pipe 3 is fixedly connected to the end of the inspection vehicle 1; a wind direction cloth 31 is fixedly connected to the end of the support pipe 3; during operation, when wind occurs, it will cause the wind direction cloth 31 to swing. At this time, the wind force can be observed by observing the swing amplitude of the wind direction cloth 31, thereby allowing the square plate 22 to be moved more quickly; by adding the wind direction cloth 31, the influence of wind force can be quickly judged by the swing of the wind direction cloth 31 when wind occurs, thereby increasing the reference for wind force and making inspection more convenient.

[0023] like Figures 3 to 4 As shown, a baffle 4 is fixed to the top of the detection vehicle 1; the baffle 4 is located between the wide-angle camera 17 and the wind direction cloth 31 and is set at an angle; during operation, when the paint is sprayed, the detection vehicle 1 is in a moving state, and some paint will approach the detection vehicle 1. At this time, the baffle 4 will block these paints; by adding the baffle 4, the sprayed paint can be intercepted, thereby reducing the contact between the paint and the detection component 11.

[0024] like Figures 3 to 4 As shown, an illumination lamp 5 is fixedly connected to the end of the inspection vehicle 1; multiple illumination lamps 5 are installed on the inspection vehicle 1; during operation, when entering a deeper area, a pair of illumination lamps 5 can be turned on to supplement the light when the internal lighting is poor, thereby increasing the observation effect of the wide-angle camera 17 on the tunnel; by adding illumination lamps 5, the observation environment of the wide-angle camera 17 can be supplemented, thereby increasing the convenience when observing cracks in the tunnel and increasing the surrounding light.

[0025] like Figure 5 As shown, a pair of guide plates 6 are fixed to the end of the square plate 22; the guide plates 6 are symmetrically arranged on the square plate 22; during operation, after the square plate 22 intercepts the wind force, some of the wind force will move from the guide plates 6, causing it to separate upward and downward, thereby reducing the pushing force on the square plate 22; by adding guide plates 6, the wind force received by the square plate 22 can be guided, thereby reducing the resistance during movement and increasing the smoothness of movement.

[0026] Working principle: During operation, the inspection vehicle 1 is first placed on the ground, and then the drive assembly 12 moves the wheels into the tunnel. Simultaneously, the wide-angle camera 17 is connected to the display screen, transmitting the ground image captured by the wide-angle camera 17 to the display screen. When a crack appears in the image, the drive assembly 12 activates the delivery pump 14. When the delivery pump 14 starts, it draws biodegradable paint from the hopper 18, which then enters the delivery pipe 15 and is sprayed out through the nozzle 16. This spraying marks the crack, allowing for rapid marking of the crack with pigment. After marking, the vehicle continues to move forward, marking subsequent cracks in sequence. When inspecting the tunnel, if wind affects the paint application, the servo motor 2 can be activated to drive the support plate 21. When the support plate 21 rotates, it drives the square plate 22 to rotate, and then the square plate 22 moves in front of the nozzle 16, thereby blocking the wind in front. When the wind appears, it will drive the wind direction cloth 31 to swing. At this time, the wind force can be observed by observing the swing amplitude of the wind direction cloth 31, so that the square plate 22 can be moved more quickly. When the paint is sprayed, the detection vehicle 1 is in a moving state, and some paint will approach the detection vehicle 1. At this time, the baffle 4 will block this paint. When entering a deeper area, a pair of lights 5 can be turned on to supplement the light when the internal light is poor, and increase the observation effect of the wide-angle camera 17 on the tunnel. After the square plate 22 intercepts the wind, some of the wind will move from the guide plate 6, causing it to separate upward and downward, thereby reducing the pushing of the square plate 22.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
