Technical Field

[0001] The invention belongs to the technical field of dam crack detection, in particular to a water conservancy dam crack detection device. Background Art

[0002] As an important part of water conservancy projects, dams undertake important tasks such as flood control, water storage, and irrigation. Cracks are one of the common diseases in dam structures. Their occurrence and development are often closely related to the stress state, material properties, and environmental factors of the dam. If cracks and other safety hazards appear in the dam, it may lead to a decrease in the dam's flood control capacity and even cause flood disasters. By detecting cracks in the dam, safety hazards can be discovered and dealt with in a timely manner, thereby improving the dam's flood control capacity and reducing the occurrence of water conservancy disasters.

[0003] However, in reality, crack detection of water conservancy dams is mainly carried out by manpower.

[0016] Preferably, the output end of the second motor passes through the two vertical plates, and the rotating wheel is fixedly connected to the output end of the second motor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

[0038] Specifically, a first motor 21 is provided in the housing 1, and a worm 22 is fixedly connected to the output end of the first motor 21. The first motor 21 is used to provide support force for the worm 22, and the worm 22 is used to support the support rod 23 and the detector 24, and drive the support rod 23 and the detector 24 to rotate.

[0039] Furthermore, a worm gear 252 is rotatably connected to the receiving block 251, a first gear 253 is fixedly connected to the worm gear 252, a first half gear 254 is fixedly connected to the first gear 253, a second gear 255 is rotatably connected to the receiving block 251, a second half gear 256 is fixedly connected to the second gear 255, and a rack 258 is fixedly connected to the movable frame 257.

[0041] As can be seen from the above, when it is necessary to detect cracks in the water conservancy dam, the first motor 21 is started. Since the output end of the first motor 21 is fixedly connected to the worm 22, the worm 22 rotates as the first motor 21 is started, and the support rod 23 slidably connected to the worm 22 rotates accordingly.

Through up and down reciprocating motion and all-round rotation, the detection head can cover every corner of the dam surface, ensuring that all potential cracks are detected without omission, without manual intervention, and reducing the risk of personnel working in high-risk areas.

[0042] Embodiment 2:

[0043] See also Figure 4 - Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that a stabilizing component 3 is provided in the shell 1, and the stabilizing component 3 includes an L-shaped rod 31 symmetrically rotatably connected to the inner wall of the shell 1, and the ends of the two L-shaped rods 31 are rotatably connected to the down-pressing rod 32, and the two L-shaped rods 31 are rotatably connected to the ends away from the down-pressing rod 32 with a connecting seat 33, and an electric push rod 34 is fixedly connected to the inner wall of the shell 1, the L-shaped rod 31 is used to receive the down-pressing rod 32 and to drive the down-pressing rod 32 to be pressed down, and the down-pressing rod 32 is pressed down until it touches the ground, the connecting seat 33 is used to drive the L-shaped rod 31 to rotate on the inner wall of the shell 1 and press the down-pressing rod 32, and the electric push rod 34 is used to provide driving force for the down-pressing rod 32.

[0044] Specifically, a spring 321 is disposed in the lower pressing rod 32 , and a protrusion 322 is fixedly connected to the end of the spring 321 . The spring 321 is used to provide elastic force for the protrusion 322 , and the protrusion 322 is in direct contact with the ground.

[0045] Furthermore, two L-shaped rods 31, lower pressure rods 32, connecting seats 33 and electric push rods 34 are each provided and are symmetrically arranged. Multiple L-shaped rods 31 and lower pressure rods 32 are symmetrically arranged around the shell 1 to maintain the stability of the overall device. The protrusion 322 is slidably connected to the lower pressure rod 32, and the size of the protrusion 322 is adapted to the size of the opening of the lower pressure rod 32.

[0046] As can be seen from the above, when the cracks in the water conservancy dam are detected and the entire device reaches the target area, the two electric push rods 34 are started, and the two electric push rods 34 push the two connecting seats 33 to move downward. Since one end of the L-shaped rod 31 is rotatably connected to the connecting seat 33, the downward pressure of the connecting seat 33 drives multiple L-shaped rods 31 to rotate in the opposite direction and be connected to the inner wall of the shell 1, and drives multiple downward pressure rods 32 to be pressed down, so that multiple downward pressure rods 32 are in contact with the ground, and the protrusion 322 is squeezed by the downward pressure rod 32 and slidably connected in the downward pressure rod 32, and the spring 321 is tightened. Through the setting of the spring 321 and the protrusion 322, the entire device is kept in a horizontal and stable state on the ground. The stabilizing component 3 can ensure that the detection device can remain horizontal and stable under various terrain conditions, which enables the detection device to be more widely used in different types of dam crack detection work, and avoids measurement errors caused by shaking or tilting of the device, which is crucial for the accurate measurement of parameters such as the width and depth of the cracks, and helps to improve the accuracy of detection.

[0047] Embodiment three:

[0049] Specifically, a rotating wheel 44 is rotatably connected between the two vertical plates 43, a second motor 45 is provided in the shell 1, and two grippers 46 are provided on the circumference of the rotating wheel 44. The rotating wheel 44 is used to drive the grippers 46 to rotate and grip the ground. The second motor 45 is used to provide driving force for the rotating wheel 44, and the grippers 46 rotate and grip the ground to drive the entire device to overcome obstacles.

[0050] Furthermore, the output end of the second motor 45 passes through the two vertical plates 43 , and the rotating wheel 44 is fixedly connected to the output end of the second motor 45 . The rotating wheel 44 is driven by the second motor 45 to rotate on the two vertical plates 43 .

[0051] As can be seen from the above, when the entire device encounters an obstacle or a small ditch during driving, the switch 41 is squeezed by the obstacle or the small ditch, triggering the switch 41, and the second motor 45 is started. Because the output end of the second motor 45 passes through the two vertical plates 43, and the rotating wheel 44 is fixedly connected to the output end of the second motor 45, the rotating wheel 44 is driven to rotate on the two vertical plates 43 and rotate in the slot 42 as the second motor 45 is started. The gripper 46 provided on the rotating wheel 44 rotates and grasps the ground in turn as the rotating wheel 44 rotates, helping the device to overcome obstacles, so that the device can easily cross various obstacles on the dam, thereby expanding the detection range, ensuring comprehensive monitoring of the overall crack situation of the dam, and ensuring that the detection device can maintain a stable operating state under various terrain conditions, thereby improving the adaptability and reliability of the device.
