Description

Technical Field

[0001] The invention relates to the technical field of underwater detectors, and more specifically to an underwater detector for a sluice and electric drainage station. Background Art

[0002] A sluice is a low-head hydraulic structure built on a river or channel that uses a gate to control flow and adjust water levels. Closing the gate can intercept floods, prevent tides, or raise upstream water levels to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industrial water, and domestic water. Opening the gate can discharge floods, waterlogging, abandoned water, or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices are widely used as structures for retaining, discharging, or taking water. Electric drainage stations are water conservancy facilities for drought prevention and flood control. They are mostly located in plain areas. In the rainy season, water pumps are used to remove water from low-lying areas to prevent waterlogging; in the dry season, water pumps are used to divert water for irrigation to prevent drought. Sluice gates and electric drainage stations are important water conservancy infrastructure for flood control, drainage and water resource scheduling. During use, for safe operation, it is usually necessary to regularly use detectors to detect the settlement displacement, joint misalignment, scouring conditions, structural integrity, etc. of underwater buildings or other components of sluice gates or electric drainage stations.

[0003] Traditional underwater inspection of sluice gates or electric drainage stations is mostly carried out by underwater detectors. Existing underwater detectors mostly consist of a telescopic body and various optical detection head structures. They detect the underwater environment of sluice gates or electric drainage stations through optical scanning and imaging technology. However, existing detectors have the following defects: Most existing underwater detectors are manually held and placed in water. During the detection process, human body shaking will affect the detection accuracy of the optical detection head. In addition, the optical detection heads of most existing detectors are exposed to the air and are eroded by the air for a long time, which shortens the service life of the optical detection head or affects the accuracy of the detection data.

[0023] See also Figure 1-Figure 8As another preferred embodiment of the present application, the transmission structure includes an air pipe winding box 14, a connecting seat 22, a connecting air pipe 15 and an inflatable member.

The free end of the connecting air pipe 15 is connected to the protective component. The telescopic outer tube 1 is provided with a catheter bracket 4 for providing guidance for the connecting air pipe 15. The inflatable member is arranged on the mounting platform 17 and connected to the lifting platform 20. The inflatable member is connected to the connecting air pipe 15 in the winding box through the connecting seat 22.

The other end of the piston rod 27 is slidably inserted in the inflating tube 21. The inflating tube 21 is connected to the connecting air pipe 15 through the connecting seat 22.

[0025] When the entire device is controlled to be supported on the ground, the lifting platform 20 can be controlled to move downward relative to the mounting platform 17, thereby controlling the piston rod 27 to move downward along the inflation tube 21, and then injecting the air in the inflation tube 21 into the connecting seat 22.

[0028] When the winding motor 6 is powered on and rotated and the winding disk 7 is controlled to release the connecting rope, the friction resistance between the connecting rope and the detection disk 10 can drive the detection disk 10 to rotate, thereby controlling the rotation of the clamping shaft 11. When the clamping shaft 11 rotates, it can drive the threaded shaft 12 to rotate. Under the action of the threaded cooperation between the threaded shaft 12 and the detection box 8, the pointing needle 13 can be driven to move along the scale 9, thereby facilitating the staff to monitor the water depth of the optical detection head 40 in real time.

[0032] It should be noted that the direction adjustment motor 38 in this embodiment can be a stepper motor or a servo motor, which is not specifically limited in this embodiment, and its specific model and type can be adaptively changed according to the actual measurement accuracy and measurement environment.

[0033] When the inflatable part is working, the air enters the cylinder 32 along the connecting air pipe 15, which can drive the cylinder 32 to extend. When the cylinder 32 extends, the mounting frame 37 can be controlled to move along the transverse guide groove 30, thereby driving the connecting rod 35 and the second dustproof box 33 to move in the horizontal direction. Under the sliding cooperation between the connecting rod 35 and the oblique guide groove 31, the second dustproof box 33 can move in the horizontal direction and simultaneously move in the vertical direction, thereby avoiding obstruction to the detection range of the optical detection head 40.

[0034] How this application works: When it is necessary to inspect the underwater environment of the sluice electric pumping station, the staff holds the pull handle 16 and controls the pull handle 16 to rotate along its hinge, and then rotates the locking rod 25 to fix the position of the pull handle 16. When the pull handle 16 rotates, it can drive the lifting platform 20 to move in the vertical direction relative to the mounting platform 17 under the action of the first push arm 18 and the slider 19, so that under the action of the second push arm 28 and the connecting head 26, the supporting feet 23 are driven to expand toward both sides along the expansion seat 24, thereby realizing the bottom support of the entire device, and in the process of the lifting platform 20 moving downward, the piston rod 27 is controlled to move downward along the inflation tube 21, and then the air in the inflation tube 21 is injected into the connecting seat 22, and the air in the connecting seat 22 enters the air pipe The air is input into the winding box 14 and into the connecting air pipe 15, so that when the air enters the cylinder 32 along the connecting air pipe 15, the cylinder 32 can be driven to extend. When the cylinder 32 extends, the mounting frame 37 can be controlled to move along the transverse guide groove 30, thereby driving the connecting rod 35 and the second dustproof box 33 to move in the horizontal direction. Moreover, under the sliding cooperation between the connecting rod 35 and the oblique guide groove 31, the second dustproof box 33 can move in the horizontal direction and simultaneously move in the vertical direction, thereby avoiding obstruction to the detection range of the optical inspection head 40. Then, the winding motor 6 is controlled to be powered on and rotated to drive the winding disk 7 to rotate to release the connecting rope, thereby extending the telescopic tube and controlling the optical inspection head 40 to go into the water for detection. When the winding motor 6 is powered on and the winding disk 7 is controlled to release the connecting rope, the friction resistance between the connecting rope and the detection disk 10 can drive the detection disk 10 to rotate, thereby controlling the rotation of the clamping shaft 11. When the clamping shaft 11 rotates, it can drive the threaded shaft 12 to rotate. Under the threaded cooperation between the threaded shaft 12 and the detection box 8, it can drive the pointing needle 13 to move along the scale 9, so that the staff can monitor the depth of the optical detection head 40 in real time. And by controlling the direction adjustment motor 38 to be powered on and rotated, the connection platform 39 can be controlled to rotate, thereby adjusting the detection range of the optical detection head 40, and when the optical detection head 40 is controlled to rise from underwater in the later stage, the water pump 36 can be controlled to work to drain the water in the first dustproof box and the second dustproof box 33 to prevent the optical detection head 40 from being immersed in water for a long time and being damaged.
