Description

Technical Field

[0001] The invention relates to the technical field of rock crack water flow detection, and in particular to a rock crack water flow ultrasonic detection device. Background Art

[0002] Ultrasonic detection of rock flow is a method that uses ultrasonic technology to examine the flow characteristics of water in rock fractures. This technology is mainly used in the fields of geology, mining, hydrology and environmental science to understand the flow of groundwater, the permeability of fractures and the distribution of water in rock formations.

[0003] Existing ultrasonic detection of water flow in rock cracks usually involves inserting an ultrasonic detector into the rock cracks to detect water flow. However, rock cracks can easily become larger due to factors such as earthquakes, groundwater flow, or geological tectonic movements. People are unable to move the ultrasonic detector to the depths of the rock cracks in time, which can easily affect the accuracy of water flow detection. In addition, the cracks can easily become smaller and closed due to the pressure of the overlying rock strata or the precipitation of minerals filling the cracks, which can easily cause damage to the ultrasonic detector.

[0004] Therefore, it is necessary to design a rock crevice water flow ultrasonic detection device which can move the ultrasonic detector to the deep rock crevice in time when the rock crevice becomes larger to improve the detection accuracy, and can withdraw the ultrasonic detector in time when the rock crevice becomes smaller to avoid damage to the ultrasonic detector. Summary of the invention

The present invention provides an ultrasonic detection device for water flow in rock crevices, which is capable of moving the ultrasonic detector to the deep part of the rock crevices in time when the rock crevices become larger, thereby improving the detection accuracy, and is capable of withdrawing the ultrasonic detector in time when the rock crevices become smaller, thereby avoiding damage to the ultrasonic detector.

[0030] A rock fracture water ultrasonic detection device, such as Figure 1 and Figure 2 As shown, it includes a support frame 1, a connecting frame 2, a detection mechanism 3, a moving mechanism 4 and a guiding mechanism 5. The support frame 1 is provided with two front and rear parts, and the left and right parts of the support frame 1 are provided with installation holes for easy fixed installation.

The connecting frame 2 is provided with a moving mechanism 4 capable of timely moving detection, and the detection mechanism 3 is provided with a guiding mechanism 5 capable of timely moving out.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the detection mechanism 3 includes a fixed connecting bracket 30, a first guide roller 31, a connecting rod 32 and an ultrasonic detector 33. The left and right parts of the connecting frame 2 are connected with three fixed connecting brackets 30. The left part of the fixed connecting bracket 30 is provided with a docking groove for easy splicing. The fixed connecting bracket 30 is rotatably connected with the first guide roller 31. A connecting rod 32 is placed between the first guide rollers 31, and an ultrasonic detector 33 is clamped on the right side of the connecting rod 32.

[0032] like Figure 1 and Figure 6 As shown, it also includes a moving mechanism 4, which includes a connecting and fixing frame 40, a motor 41, a rotating column 42, a gear 43 and a rack 44. The middle part of the connecting frame 2 is connected to the left and right connecting and fixing frames 40, the rear part of the left connecting and fixing frame 40 is connected to the motor 41, and the rotating column 42 is connected to the output shaft of the motor 41.

The upper side of the connecting rod 32 is connected to the rack 44, and the gears 43 are all meshed with the rack 44.

[0033] like Figure 1 and Figure 7 As shown, a guide mechanism 5 is also included, which includes a fixed bracket 50, a sensor 51, a connecting plate 52, a second guide roller 53 and a torsion spring 54. The right part of the ultrasonic detector 33 is connected to the front and rear fixed brackets 50, the upper sides of the fixed brackets 50 are connected to the sensors 51, the sensors 51 are electrically connected to the motor 41, the fixed brackets 50 are rotatably connected to the connecting plates 52, the left part of the connecting plates 52 is rotatably connected to the second guide roller 53, the second guide roller 53 is provided with anti-skid grooves to facilitate anti-skid, and the upper and lower sides of the connecting plates 52 are connected to the adjacent fixed brackets 50 with torsion springs 54.

[0034] When using the device, first fix the support frame 1 in the ultrasonic detection area of ​​rock crack water flow through the mounting hole, then dock the ultrasonic detector 33 with the connecting rod 32, and then dock a plurality of connecting rods 32 through the docking groove according to needs, so that the connecting rods 32 can be spliced, which is convenient for inserting the ultrasonic detector 33 into rock cracks of different lengths, thereby improving the flexibility of using the device. After the splicing is completed, the ultrasonic detector 33 is passed through the connecting frame 2 and the connecting and fixing frame 40, so that the connecting rod 32 contacts the first guide roller 31, drives the first guide roller 31 to rotate on the fixed connecting bracket 30, and guides the ultrasonic detector 33 through the first guide roller 31 so that the ultrasonic detector 33 extends into the rock crack, so that the connecting plate 52 rotates inwardly on the fixed bracket 50, and the torsion spring 54 is deformed. While the connecting rod 32 moves, it drives the second guide roller 53 to rotate, and anti-skid is performed through the anti-skid pattern. Detection is performed through the ultrasonic detector 33. When the sensor 51 detects that the rock crack suddenly increases, the control motor 41 is started so that the gear 43 on the left The gear 43 and the rack 44 mesh with each other, driving the connecting rod 32 to move to the right, so that the gear 43 on the right rotates, driving the rotating column 42 on the right to rotate, and guiding the connecting rod 32 through the gear 43 on the right, so that the ultrasonic detector 33 is inserted into the deepest part of the rock crack. When the sensor 51 detects that the rock crack becomes smaller, the control motor 41 starts in the reverse direction, driving the gear 43 on the left to rotate in the reverse direction, the gear 43 and the rack 44 mesh with each other, driving the connecting rod 32 to move to the left, so that the gear 43 on the right rotates, driving the ultrasonic detector 33 to move to the left, and driving the second guide roller 53 to rotate, so that the ultrasonic detector 33 is evacuated from the rock crack in time, so that the ultrasonic detector 33 can be moved to the deep part of the rock crack in time when the rock crack becomes larger, thereby improving the detection accuracy, and the ultrasonic detector 33 can be withdrawn in time when the rock crack becomes smaller, so as to avoid damage to the ultrasonic detector 33. After the ultrasonic detector 33 is withdrawn, the torsion spring 54 recovers, driving the connecting plate 52 to rotate and reset.

[0035] like Figure 1 , Figure 8 and Fig. 9As shown, a prompt mechanism 6 is also included, which includes a guide block 60, a first spring 61, a guide frame 62, a sliding block 63, a second spring 64, a button 65 and an alarm 66.

The alarm 66 and the button 65 are connected by wires.

[0036] When the prompt mechanism 6 of the present device is used, an alarm can be issued when the rock crack becomes smaller. When the gear 43 rotates in the opposite direction, it drives the left rotating column 42 to rotate, causing the guide block 60 to rotate, driving the sliding block 63 to rotate along the guide frame 62, and the second spring 64 is squeezed and contracted, causing the sliding block 63 to contact the button 65, thereby causing the alarm 66 to sound an alarm, thereby being able to issue an alarm when the rock crack becomes smaller, so as to promptly remind people to take risk avoidance measures and ensure the safety of personnel and equipment. When the sliding block 63 no longer rotates, the guide block 60 moves backward, the first spring 61 recovers, causing the second spring 64 to recover, and driving the sliding block 63 to move and reset.
