Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and in particular relates to a river slope crack detection device for water conservancy projects. Background Art

[0002] In water conservancy projects, river slope cracks are a common safety hazard that may lead to river slope collapse and soil erosion. In order to timely detect and monitor the situation of river slope cracks, a river slope crack detection device can be used.

[0003] The river slope crack detection device usually includes sensors, data acquisition equipment and data processing software. The sensor can detect the cracks by monitoring the displacement changes on the river slope surface, and the data acquisition equipment can transmit the data obtained by the sensor to the data processing software for analysis and processing.

[0004] Through the river slope crack detection device, engineering personnel can monitor the situation of river slope cracks in real time, promptly discover the changing trend of cracks, and warn of possible safety risks, so as to take corresponding measures to deal with them and ensure the safe and stable operation of water conservancy projects.

[0005] The existing water conservancy project river slope crack detection device has the following disadvantages during use:

[0006] ① On the one hand, the detection device is pushed to move on the river slope, and the detection equipment installed on it can detect cracks on the river slope surface. However, during the detection process, the detection equipment can only perform linear detection during the movement, and cannot move back and forth, resulting in a limited range of the river slope surface to be detected;

[0007] ② The second aspect is that a cleaning structure is generally used to clean the dust on the surface of the river slope. However, after the cleaning structure has been used for a long time, the friction between the cleaning structure and the river slope surface has caused the cleaning structure to lose its original cleaning effect. However, the cleaning structure on the existing detection device is not easy to disassemble and replace. Therefore, a water conservancy project river slope crack detection device is needed.

[0035] It also includes a linkage reciprocating transmission structure 5 and a detachable linkage structure 7. The linkage reciprocating transmission structure 5 is installed on the mobile base 1 and is connected to the wire 41 and the detection probe 42. The linkage reciprocating transmission structure 5 can manually push the detection device to move, and can actively make the detection probe 42 move back and forth left and right at the bottom of the mobile base 1, so as to facilitate detection of different position areas on the river slope surface.

[0036] The detachable linkage structure 7 is installed on the mobile base 1 and is connected to the brush roller 6.
