Description

Technical Field

[0001] This invention relates to the field of dam crack detection device technology, specifically a dam crack detection device based on intelligent sensors. Background Technology

[0002] As an important water conservancy project, the structural integrity of dams is directly related to flood control safety. Cracks are one of the common defects in dams. If they are not detected and repaired in time, they may lead to serious consequences such as seepage, piping, or even dam failure. Currently, the detection of dam cracks mainly relies on manual inspection or simple equipment, which has the following significant drawbacks: 1. When traditional detection devices move on the surface of an inclined dam, the slope can cause the sliding speed to become uncontrollable, or the center of gravity to shift and cause overturning. The risk is even higher in rainy, foggy, or slippery environments, which can affect the detection process. 2. Although the existing setup can detect cracks, it cannot clean up foreign objects such as soil and gravel around the cracks. The presence of foreign objects can easily lead to deviations in the detection data and affect the accuracy of crack size measurement. 3. The existing equipment does not have an automatic crack location marking function. After the inspection is completed, it is difficult for staff to quickly locate the crack location, which causes inconvenience to subsequent repair work. Summary of the Invention

[0003] The purpose of this invention is to provide a dam crack detection device based on intelligent sensors to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dam crack detection device based on intelligent sensors, comprising a traveling vehicle, a photovoltaic power generation system installed on the traveling vehicle, a storage battery installed on the traveling vehicle, a control module installed on the traveling vehicle, a communication module fixed to the traveling vehicle on the side of the control module, a first vertical plate and a second vertical plate vertically fixed to the lower end face of the traveling vehicle, an industrial camera and a laser displacement sensor fixed on the first vertical plate, a deceleration mechanism provided on the lower side of the traveling vehicle, and the deceleration mechanism uses gravity to achieve self-regulation of the traveling speed of the traveling vehicle, a marking mechanism for marking the crack location installed on the second vertical plate, and a cleaning mechanism for cleaning the crack fixed on the lower side of the traveling vehicle, and the cleaning mechanism can clean loose and hollow materials around the crack.

[0005] Preferably, the traveling vehicle is fixed with a pull ring, and a rotating shaft is connected to the bearing on the traveling vehicle. Wheels are symmetrically fixed to the rotating shaft. Auxiliary wheels are symmetrically rotated and installed at an angle on the traveling vehicle. The lower end face of the auxiliary wheel is flush with the lower end face of the wheel, and the lower end face of the wheel is lower than the lower end face of the first vertical plate and the second vertical plate. The rotating shaft is connected to the deceleration mechanism. The wheels can ensure that the device can travel normally on the inclined dam body. The auxiliary wheels can provide auxiliary support to ensure the stability of the device's movement and prevent the device from tipping over, thereby ensuring the stable operation of the device.

[0006] Preferably, the deceleration mechanism includes a deceleration wheel fixed on a rotating shaft, and the deceleration wheel cooperates with a friction plate to achieve deceleration. The friction plate is fixed on a bracket. Through the friction between the deceleration wheel and the friction plate, the walking speed of the entire device can be controlled, thereby avoiding the device from overturning due to excessive movement speed on the inclined dam body, and further ensuring the stability of the device's movement.

[0007] Preferably, one end of the bracket and the slide rod are fixed to each other, and the slide rod is slidably connected to the lower end face of the traveling vehicle. A first spring is fixed between the bracket and the traveling vehicle, and a counterweight is fixed to the other end of the slide rod. The contact pressure between the friction plate and the reduction wheel can be adjusted by the weight of the counterweight, thereby adjusting the friction between the friction plate and the reduction wheel. This provides a basic guarantee for controlling the movement speed of the device. The inclination angle of the dam body is proportional to the friction between the friction plate and the reduction wheel, ensuring the safe operation of the device.

[0008] Preferably, the marking mechanism includes a liquid storage tank fixed to the side of the second vertical plate, and a solenoid valve is installed at the lower end of the liquid storage tank. The solenoid valve is controlled by a control module and is connected to a diverter plate through a conduit. A coating roller is connected to the lower bearing of the diverter plate, and leakage holes are evenly opened on the lower end face of the diverter plate above the coating roller. The lower end face of the coating roller is flush with the lower end face of the wheel. With the above structure, when a crack in the dam body is detected, the solenoid valve is opened, allowing the marking liquid to drip onto the coating roller through the solenoid valve, conduit, diverter plate and leakage holes, so as to mark the location of the crack.

[0009] Preferably, the cleaning mechanism includes a motor fixed on a traveling vehicle, with the output end of the motor connected to the cleaning roller. The cleaning roller bearing is connected to the traveling vehicle. Meanwhile, brush plates are nested at equal angles on the cleaning roller. The brush plates are locked to the cleaning roller by bolts. The motor drives the brush plates to rotate, which provides a basic guarantee for cleaning foreign objects on the dam surface and for subsequent inspection. Furthermore, the nested connection between the brush plates and the cleaning roller allows for easy disassembly and replacement of the brush plates.

[0010] Preferably, a round rod is evenly slidably connected to the cleaning roller, and a second spring is fixed between the round rod and the cleaning roller. A metal ball is also fixed on the round rod. The cleaning roller drives the round rod and the metal ball to rotate. Through the collision of the metal ball with the dam body, stubborn impurities such as mud on the dam body surface can be broken up to facilitate cleaning, and loose and hollow materials on the sides of the cracks in the dam body can be cleaned to facilitate subsequent manual repair.

[0011] Preferably, the cleaning roller is also symmetrically fixed with coaxial reciprocating screws, and the reciprocating screws are connected to the movable frame. The movable frame is symmetrically fixed with pistons, and the pistons are slidably connected to the sealing cylinder. The sealing cylinder is fixed to the first vertical plate, and a one-way air inlet valve and a one-way air outlet valve are installed on the sealing cylinder. The reciprocating screws can drive the movable frame to reciprocate, thereby driving the piston to slide back and forth in the sealing cylinder. With the help of the one-way air inlet valve and the one-way air outlet valve, a basic guarantee can be provided for the one-way exhaust of the sealing cylinder.

[0012] Preferably, the one-way exhaust valve on the sealing cylinder is connected to the guide plate via a conduit, and the guide plate is rotatably connected to the first vertical plate. The guide plates are evenly distributed on the first vertical plate, and adjacent guide plates are connected by conduits. Nozzles are evenly installed on the lower end face of the guide plate. Through the one-way exhaust of the sealing cylinder, gas can enter the guide plate and be sprayed out through the nozzles. The high-speed airflow sprayed out by the nozzles can perform secondary cleaning of debris, ensuring the cleanliness of the dam surface or cracks, so as to facilitate subsequent testing.

[0013] Preferably, a gear is fixed on the rotating shaft of the guide plate, and the gear meshes with a rack. The rack is fixed to one end of the support rod, while the other end of the support rod is fixed to the movable frame. When the movable frame reciprocates, it synchronously drives the support rod and the rack to move. Through the meshing transmission between the rack and the gear, the guide plate and the nozzle can reciprocate, thereby adjusting the angle of the airflow sprayed from the nozzle and increasing the cleaning range.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This intelligent sensor-based dam crack detection device utilizes two intelligent detection components: an industrial camera and a laser displacement sensor. The industrial camera can monitor the presence of cracks on the dam surface in real time, while the laser displacement sensor can accurately measure the size parameters of the cracks (width, depth, etc.). The two work together to effectively overcome the limitations of a single detection component. Simultaneously, a cleaning mechanism can remove foreign objects such as soil and gravel from the dam surface in advance. Stubbornly adhered foreign objects are broken by striking with metal balls, and surface impurities are swept away by a brush. It can also clean impurities inside the cracks and loose, hollow materials around them, avoiding detection errors caused by foreign objects covering the cracks. This ensures the accuracy and completeness of crack detection data and provides reliable quantitative data support for dam crack repair. 2. This dam crack detection device based on intelligent sensors is equipped with wheels and inclined auxiliary wheels on its traveling vehicle. The auxiliary wheels are flush with the end faces of the wheels, which can provide stable support for the device and effectively prevent the device from overturning when moving on inclined dams. At the same time, the deceleration mechanism uses gravity to achieve self-regulation of the traveling speed. When the counterweight is tilted, it drives the friction plate to contact the deceleration wheel to generate friction. The device can automatically adjust its sliding speed according to the degree of dam inclination, which not only prevents the speed from affecting the detection accuracy, but also avoids the risk of overturning. This significantly improves the safety and stability of the device in complex dam environments. The first spring can realize the reset of the friction plate to ensure the normal movement of the device on horizontal or slightly inclined dams. 3. This intelligent sensor-based dam crack detection device features a marking mechanism that automatically controls a solenoid valve to open when a crack is detected. This allows marking pigment from the storage tank to drip through a diversion plate onto a coating roller, which then applies the marking to the crack location. This automatic marking enables workers to quickly locate cracks during subsequent repair work, avoiding the need for secondary inspections. This significantly reduces the workload of workers, improves dam repair efficiency, and solves the problem of existing detection equipment being unable to mark cracks simultaneously. 4. This dam crack detection device based on intelligent sensors features a cleaning mechanism that uses a motor-driven cleaning roller to perform multi-level impurity cleaning. The cleaning roller utilizes metal balls that adapt to the dam body under the elastic action of a second spring, breaking up stubbornly adhered soil and gravel on the dam surface by impact, while simultaneously cleaning loose, hollow materials around the cracks. Additionally, brushes mounted at equal angles on the cleaning roller rotate synchronously to sweep away loose impurities from the dam surface and within the cracks. The brushes are bolted to the cleaning roller for easy disassembly and replacement. Furthermore, the rotation of the cleaning roller drives a coaxial reciprocating screw, which in turn drives a movable frame to reciprocate, causing a piston to slide within a sealed cylinder. This, combined with the one-way inlet and outlet valves of the sealed cylinder, generates a high-speed airflow. The airflow enters the guide plate through a duct and is ejected through a nozzle. Simultaneously, the movable frame, via a support rod, drives a rack to reciprocate. The rack meshes with gears on the guide plate's rotating shaft, driving the guide plate and nozzle to swing back and forth, expanding the airflow's sweeping range and achieving secondary cleaning of residual debris on the dam surface, ensuring complete exposure of the cracks. 5. This intelligent sensor-based dam crack detection device uses a photovoltaic power generation system in conjunction with a battery to provide clean energy for the device. It does not require an external power source and is suitable for outdoor dam operation environments without power supply, achieving energy saving and consumption reduction. The device can automatically complete operations such as movement, deceleration, cleaning, detection, and marking throughout the entire process, reducing manual intervention. This not only improves the efficiency of detection operations but also reduces the safety risks of manual inspection in high-risk dam environments. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7 This invention provides a technical solution: a dam crack detection device based on intelligent sensors, including a traveling vehicle 1, a photovoltaic power generation system 2 installed on the traveling vehicle 1, a storage battery 3 installed on the traveling vehicle 1, a control module 4 installed on the traveling vehicle 1, a communication module 5 fixed on the side of the control module 4, a first vertical plate 6 and a second vertical plate 10 vertically fixed on the lower end face of the traveling vehicle 1, an industrial camera 7 and a laser displacement sensor 8 fixed on the first vertical plate 6, a deceleration mechanism 9 provided on the lower side of the traveling vehicle 1, and the deceleration mechanism 9 uses gravity to achieve self-regulation of the traveling speed of the traveling vehicle 1, a marking mechanism 11 for marking the crack location is installed on the second vertical plate 10, and a cleaning mechanism 12 for cleaning the crack is also fixed on the lower side of the traveling vehicle 1, and the cleaning mechanism 12 can clean the loose and hollow materials around the crack.

[0019] A pull ring 101 is fixed on the traveling vehicle 1, and a rotating shaft 102 is connected to the traveling vehicle 1 by a bearing. Wheels 103 are symmetrically fixed on the rotating shaft 102. An auxiliary wheel 104 is symmetrically rotated and mounted on the traveling vehicle 1 at an angle. The lower end face of the auxiliary wheel 104 is flush with the lower end face of the wheel 103, and the lower end face of the wheel 103 is lower than the lower end faces of the first vertical plate 6 and the second vertical plate 10. The rotating shaft 102 is connected to the deceleration mechanism 9. The deceleration mechanism 9 includes a deceleration wheel 901 fixed on the rotating shaft 102. The deceleration wheel 901 cooperates with the friction plate 902 to achieve deceleration. The friction plate 902 is fixed on the bracket 903. One end of the bracket 903 and the slide rod 904 are fixed to each other. The slide rod 904 is slidably connected to the lower end face of the traveling vehicle 1. A first spring 905 is fixed between the bracket 903 and the traveling vehicle 1. At the same time, a counterweight 906 is fixed to the other end of the slide rod 904. When using this smart sensor-based dam crack detection device, such as Figures 1-7 As shown, the traction rope is manually fixed to the pull ring 101, and then the entire device is placed on the inclined dam. At this time, the wheel 103 and the auxiliary wheel 104 are in contact with the dam surface and roll, so that the entire device can automatically move down along the inclined dam surface. During the movement of the device, the auxiliary wheel 104 can provide auxiliary support for the entire device, effectively preventing the device from overturning during the movement. When the device is placed on the inclined dam, the counterweight 906 moves relative to the traveling vehicle 1 under the action of gravity due to the tilt of the entire device. This causes the sliding rod 904, the bracket 903, and the friction plate 902 to move. The friction plate 902 contacts the reduction wheel 901 and generates pressure, which in turn generates friction between the friction plate 902 and the reduction wheel 901. This friction between the friction plate 902 and the reduction wheel 901 limits the downward speed of the entire device on the inclined dam. This prevents the device from moving too fast and affecting the normal operation of the inspection, and also prevents the device from overturning due to excessive speed, thus ensuring the safety of the device. During the movement of the device, the industrial camera 7 can monitor whether there are cracks in the dam. The laser displacement sensor 8 can monitor the size of the cracks in the dam to provide data support for subsequent repairs. Furthermore, the lower end of the wheel 103 is lower than the lower end of the first vertical plate 6 and the second vertical plate 10, which can effectively prevent the first vertical plate 6 and the second vertical plate 10 from contacting the dam surface and causing wear during the movement of the device. The cleaning mechanism 12 includes a motor 1201 fixed on the traveling carriage 1, with the output end of the motor 1201 connected to the cleaning roller 1202. The cleaning roller 1202 is also bearing-connected to the traveling carriage 1. A brush plate 1203 is nested at equal angles on the cleaning roller 1202, and the brush plate 1203 is locked to the cleaning roller 1202 by bolts. A round rod 1204 is also slidably connected to the cleaning roller 1202, and a second spring 1205 is fixed between the round rod 1204 and the cleaning roller 1202. A metal ball 1206 is also fixed to the round rod 1204. A coaxial reciprocating screw 1207 is symmetrically fixed to the cleaning roller 1202, and the reciprocating screw 1207 is connected to a movable frame 1208. Pistons 1209 are symmetrically fixed to the movable frame 1208. The piston 1209 and the sealing cylinder 1210 are slidably connected. The sealing cylinder 1210 is fixed on the first vertical plate 6, and a one-way air inlet valve and a one-way air outlet valve are installed on the sealing cylinder 1210. The one-way air outlet valve on the sealing cylinder 1210 is connected to the guide plate 1211 through a conduit. The guide plate 1211 is rotatably connected to the first vertical plate 6, and the guide plates 1211 are evenly distributed on the first vertical plate 6. Adjacent guide plates 1211 are connected through conduits. Spray nozzles 1212 are evenly installed on the lower end face of the guide plate 1211. A gear 1213 is fixed on the rotating shaft of the guide plate 1211, and the gear 1213 meshes with the rack 1214. The rack 1214 is fixed to one end of the support rod 1215, and the other end of the support rod 1215 is fixed to the movable frame 1208. During the detection process when the device is moved, such as Figures 1-7 As shown, starting the motor 1201 can drive the cleaning roller 1202, brush plate 1203, round rod 1204 and metal ball 1206 to rotate. The brush plate 1203 can clean foreign objects (adhered soil and gravel particles, etc.) on the dam surface. In order to avoid the foreign objects from sticking too tightly to the dam body and affecting the cleaning effect, the metal ball 1206 can break up stubborn foreign objects by knocking when it rotates. This further ensures the cleaning effect of the brush plate 1203 on the dam surface, thereby avoiding foreign objects covering the surface and affecting the accuracy of crack detection data. When a crack is detected, the brush plate 1203 can clean the impurities in the crack, and the knocking action of the metal ball 1206 can remove loose and hollow gravel around the crack, making the crack better exposed for subsequent detection. When the cleaning roller 1202 rotates, it synchronously drives the reciprocating screw 1207 to rotate. Through the action of the reciprocating screw 1207, the movable frame 1208 can perform orderly back-and-forth reciprocating motion. The movement of the movable frame 1208 can synchronously drive the piston 1209 to slide inside the sealing cylinder 1210. With the action of the one-way air inlet valve and one-way air outlet valve on the sealing cylinder 1210, the gas inside the sealing cylinder 1210 can flow in one direction. The air discharged through the one-way air outlet valve on the sealing cylinder 1210 enters the guide plate 1211 through the conduit and is sprayed... The nozzle 1212 sprays out a high-speed airflow that blows away residual foreign matter on the dam surface after the brush plate 1203 has cleaned it, further ensuring the cleaning effect of the dam surface. When the movable frame 1208 moves back and forth in an orderly manner, it drives the support rod 1215 and the rack 1214 to move back and forth in sync. With the meshing transmission between the rack 1214 and the gear 1213, the guide plate 1211 and the nozzle 1212 can be subjected to force and swing back and forth in an orderly manner, thereby realizing the angle adjustment of the airflow sprayed by the nozzle 1212, further increasing the blowing area and blowing effect of the airflow. The marking mechanism 11 includes a liquid storage tank 1101 fixed to the side of the second vertical plate 10, and a solenoid valve 1102 is installed at the lower end of the liquid storage tank 1101. The solenoid valve 1102 is controlled by the control module 4. The solenoid valve 1102 is connected to the diversion plate 1103 through a conduit. A coating roller 1104 is connected to the lower bearing of the diversion plate 1103. The lower end face of the diversion plate 1103 is evenly provided with leakage holes located above the coating roller 1104. The lower end face of the coating roller 1104 is flush with the lower end face of the wheel 103. During the operation of the device, such as Figures 1-7 As shown, the industrial camera 7 and laser displacement sensor 8 can detect cracks in the dam body. When a crack is detected, the detection data is fed back to the control module 4 and the monitoring backend via the communication module 5 for staff to view. At this time, the control module 4 can control the solenoid valve 1102 to open, so that the marking pigment stored in the storage tank 1101 enters the diversion plate 1103 through the solenoid valve 1102 and the conduit under the action of gravity, and drips onto the coating roller 1104 through the uniform leakage holes on the lower end face. The coating roller 1104 can be used to mark the crack location with marking pigment, so that the staff can quickly determine the repair location when repairing the dam body later. When the subsequent crack detection is completed, the solenoid valve 1102 is closed to allow for the next marking. At this time, some marking liquid will remain on the coating roller 1104, which will increase the marking distance during subsequent detection, but it will not affect the staff's ability to determine the crack location from the marking starting point.
