Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic model test scouring and silting terrain testing equipment, and particularly relates to an automatic testing device for scouring and silting terrain in hydraulic model tests. Background Art

[0002] Traditional methods for measuring erosion and siltation topography in hydraulic models primarily include manual measurement using a stylus and steel ruler, and measurement using a level. Currently, the mainstream testing method is contact measurement. During the testing process, the stylus, ruler, and tester cause varying degrees of irreversible damage to the erosion and siltation topography. Furthermore, due to manual manipulation, the coordinates and readings of elevation points are subject to certain errors. Test results are generally not highly accurate, and the number of measurement points is limited, resulting in some discrepancies from the original topography. Furthermore, traditional methods for measuring erosion and siltation topography in hydraulic models require the full participation of test personnel, resulting in labor-intensive and inefficient testing.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the technical solution of the present invention will be further described in detail below in conjunction with the drawings in the embodiments of the present invention.

[0020] Reference Figures 1 to 4 The utility model describes an automatic testing device for scouring and silting terrain in a hydraulic model test, comprising a fixed guide rail 1, a support plate, a sliding frame 10, a rangefinder 9, a longitudinal primary adjustment mechanism, a transverse adjustment mechanism, and a longitudinal secondary adjustment mechanism. The fixed guide rails 1 have two and are symmetrically arranged. The support plate is slidably arranged on the two fixed guide rails 1. The longitudinal primary adjustment mechanism can drive the support plate to perform longitudinal sliding adjustment relative to the fixed guide rail 1. The sliding frame 10 is slidably installed on the support plate. The transverse adjustment mechanism can drive the sliding frame 10 to perform transverse sliding adjustment relative to the support plate. The rangefinder 9 is slidably installed on the sliding frame 10. The longitudinal secondary adjustment mechanism can drive the rangefinder 9 to perform longitudinal sliding adjustment relative to the sliding frame 10. A laser emitter 12 is fixedly connected to the center of the bottom end of the rangefinder 9.

[0021] The longitudinal primary adjustment mechanism, the longitudinal secondary adjustment mechanism and the lateral adjustment mechanism can drive the rangefinder 9 and the laser emitter 12 to perform longitudinal, primary and lateral position adjustments to achieve automated measurement. The entire process is time-saving, labor-saving and efficient.

[0022] The support plate includes two adjustment frames 7 and two extension frames 11 . The two adjustment frames 7 are respectively slidably connected to the two fixed guide rails 1 . The two extension frames 11 are connected between the two adjustment frames 7 and are parallel to each other.

[0023] The longitudinal primary adjustment mechanism includes a longitudinal primary drive motor 17, a longitudinal primary transmission belt 5, two longitudinal primary threaded rods 6 and two longitudinal primary pulleys 4. The two longitudinal primary threaded rods 6 are respectively rotatably installed in the two fixed guide rails 1. The longitudinal primary drive motor 17 is fixedly installed in the fixed guide rail 1 and its output shaft is transmission connected to any longitudinal primary threaded rod 6. The two adjustment frames 7 are respectively threadedly connected to the two longitudinal primary threaded rods 6. The two longitudinal primary pulleys 4 are respectively transmission connected to the two longitudinal primary threaded rods 6. The longitudinal primary transmission belt 5 is wrapped around the two longitudinal primary pulleys 4.

[0024] Starting the longitudinal primary drive motor 17 can drive the longitudinal primary threaded rod 6 connected thereto to rotate. Since the two longitudinal primary threaded rods 6 are both connected to the longitudinal primary pulley 4, and the two longitudinal primary transmission pulleys 4 are connected by the longitudinal primary transmission belt 5, the two longitudinal primary threaded rods 6 can rotate synchronously under the drive of the longitudinal primary pulley 4. Since the two adjustment frames 7 are respectively threadedly connected to the two longitudinal primary threaded rods 6, the two adjustment frames 7 can be driven to move synchronously.

[0025] The lateral adjustment mechanism includes a lateral drive motor 13, a lateral transmission belt 14, two lateral threaded rods 15 and two lateral pulleys 19. The two lateral threaded rods 15 are rotatably installed in the two extension frames 11 respectively. The lateral drive motor 13 is fixedly installed in any extension frame 11 and its output shaft is transmission connected to the nearest lateral threaded rod 15. The two lateral pulleys 19 are transmission connected to the two lateral threaded rods 15 respectively. The lateral transmission belt 14 is wrapped around the two lateral pulleys 19. The sliding frame 10 is slidably installed on the extension frame 11 and is threadedly connected to the two lateral threaded rods 15.

[0026] After the transverse drive motor 13 is started, it can directly drive the transverse threaded rod 15 connected to it to rotate. Since the two transverse threaded rods 15 are both connected to the transverse pulleys 19, and the two transverse pulleys 19 are connected by the transverse transmission belt 14, the two transverse threaded rods 15 rotate synchronously under the drive of the transverse pulley 19. Since the sliding frame 10 is threadedly connected to the two transverse threaded rods 15, it can drive the sliding frame 10 to slide.

[0027] The longitudinal secondary adjustment mechanism includes a longitudinal secondary linear motor 8, a sliding frame 10 having a through slot 16 defined therein. The longitudinal secondary linear motor 8 is fixedly mounted within the sliding frame 10. The rangefinder 9 is slidably disposed within the through slot 16 and is in driving connection with the drive end of the longitudinal secondary linear motor 8. The front-to-back diameter of the laser emitter 12 is smaller than the width of the through slot 16. Activating the longitudinal secondary linear motor 8 drives the rangefinder 9 and laser emitter 12 to perform longitudinal linear motion within the through slot 16.

[0028] The bottom of the fixed rail 1 is equipped with a height-adjustable support 18, and a level 2 is installed on the side of any fixed rail 1. Adjusting the height of the support 18 can adjust the fixed rail 1, and in conjunction with the level 2, it is convenient for the operator to adjust the fixed rail 1 to a horizontal state to ensure measurement accuracy.

[0029] A controller 3 is installed on any fixed guide rail 1 , and the controller 3 is electrically connected to the rangefinder 9 , the longitudinal primary drive motor 17 , the transverse drive motor 13 , the longitudinal secondary linear motor 8 , and the laser emitter 12 .

[0030] To sum up, the working process of the present invention is as follows: first, adjust the support 18 to center the bubble of the level 2 to ensure that the fixed guide rail 1 is in a horizontal state, and then control the longitudinal primary drive motor 17 and the transverse drive motor 13 to open and close through the controller 3, and drive the rangefinder 9 to move and adjust in the longitudinal and transverse directions, so that the rangefinder 9 can be positioned to each coordinate, and then control the longitudinal secondary linear motor 8 through the controller 3 to drive the rangefinder 9 to slide on the sliding frame 10, and at the same time, under the control of the controller 3, the laser emitter 12 is used to emit laser at the specified position to measure the elevation between the terrain setting point and the reference point, and obtain the terrain elevation, thereby improving the accuracy of the measurement.
