Description

Technical Field

[0001] The present invention relates to the field of dam construction, and in particular to a device for detecting the strength of a dam in a water conservancy project. Background Art

[0002] A dam, also known as a large dam or reservoir dam, is a hydraulic engineering structure primarily used to intercept water in rivers and canals to raise water levels or regulate flow. Types include gravity dams, arch dams, and buttress dams. They typically consist of retaining, sluicing, and release structures, sometimes with specialized spillways and diversion pipe vents. Dams play an important role in flood control, power generation, irrigation, shipping, water supply, and fisheries, and are key facilities for water resource utilization and management.

[0003] Before the dam is used and after long-term use, it needs to be tested for strength to determine whether it meets the requirements of water conservancy projects. However, after the test is completed, there is a lack of markings on the areas where the dam's strength is insufficient, which makes it inconvenient for workers to carry out subsequent repair work. Summary of the Invention

[0004] In order to facilitate workers to mark defects in dams, the present application provides a water conservancy project dam strength detection device.

[0007] By adopting the above technical solution, the user drives the detection device to move on the side of the dam, and uses the detection component to detect the strength of the dam. When it is detected that the strength of the dam at that location is insufficient, the electric telescopic rod is started to drive the marking head to extend and retract to mark the dam at that location; at the same time, the height of the detection component and the marking component on the frame is changed by the sliding component, so that positions at different heights on the dam can be detected and marked.

[0009] By adopting the above technical solution, after starting the first driving member to drive the threaded rod to rotate, the sliding frame connected to the threaded rod is driven to move on the mounting frame. This method only requires starting the first driving member to drive the sliding frame to move, thereby stably performing the lifting and lowering of the sliding frame.

[0010] Preferably, the mounting bracket is rotatably mounted on the frame, and a second driving member for driving the mounting bracket to rotate on the frame is mounted on the frame.

[0011] By adopting the above technical solution, when it is necessary to inspect the inclined dam, the second driving member is started to rotate the mounting frame, and the detection component rotates with the mounting frame relative to the frame, so that it can face the inclined dam, making it easier to inspect the dam.

[0012] Preferably, the second driving member includes a first cylinder, the first cylinder is rotatably mounted on the frame, and the output end of the first cylinder is rotatably mounted on the mounting frame.

[0013] By adopting the above technical solution, the mounting bracket can be pushed to rotate on the frame by starting the first cylinder, so that the user can quickly adjust the rotation angle of the mounting bracket.

[0015] By adopting the above technical solution, the third driving member is started to drive the hinge block to move on the sliding block, and the angle of the hinge block is further adjusted so that the output end of the marking head installed on the hinge block faces the inclined dam, making it convenient for the marking head to mark on the dam after it is extended and retracted.

[0016] Preferably, the third driving member includes a second cylinder, the second cylinder is rotatably mounted on the sliding block, and the piston rod of the second cylinder is rotatably mounted on the hinge block.

[0017] By adopting the above technical solution, the second cylinder is used as a power source to drive the hinge block to move on the sliding block, which can quickly and accurately adjust the rotation angle of the hinge block, making it easier for the marking head to mark on the embankment.

[0018] Preferably, the detection assembly includes a knocking block and a third cylinder, the third cylinder is mounted on the hinge block, and the knocking block is fixedly mounted on the output end of the third cylinder.

[0019] By adopting the above technical solution, the third cylinder is started to drive the knocking block to slide and knock on the dam, thereby quickly monitoring the dam.

[0020] Preferably, a plurality of pulleys are provided at the bottom of the frame, and a handrail is installed on the frame.

[0021] By adopting the above technical solution, the entire detection device can be moved by simply pushing the frame, which makes it easy to detect and mark various parts of the dam.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When it is detected that the strength of the embankment is insufficient, the electric telescopic rod is activated to drive the marking head to extend and retract, thereby marking the embankment at that location; at the same time, the height of the detection component and the marking component on the frame is changed by the sliding component, so that positions at different heights on the embankment can be detected and marked;

[0031] When using the detection device, the worker first pushes the frame 1 to the front of the predetermined detection position of the dam, and then starts the sliding component 5 to change the position of the sliding frame 21 according to the height of the predetermined position, so as to use the detection component 3 to detect the predetermined position of the dam. When it is detected that the dam has a defect at this position, the electric telescopic rod 42 is started to drive the marking head 41 to extend and retract at this position to knock and mark the dam. Subsequent workers only need to repair the defects of the dam at this position according to the mark.
