Description

Technical Field

[0001] This utility model relates to the field of hydrological cableway technology, specifically a hydrological cableway deflection and positioning mechanism. Background Technology

[0002] A hydrological cableway is an overhead cable system that spans rivers, canyons, and other bodies of water. As an important infrastructure for hydrological monitoring, it typically consists of a main cable, a gantry, a drive unit, and a measurement pod. It enables hydrological personnel or automated instruments and equipment to pass safely and efficiently and be positioned under harsh water flow conditions, thereby completing the systematic monitoring of key hydrological elements such as cross-sectional velocity, flow rate, sediment, and water quality. It is especially suitable for special scenarios where traditional ship-based surveys are difficult to conduct, such as floods during the flood season and steep river sections. The deflection and positioning mechanism is an important structural component of the cableway.

[0003] Existing cableway deflection and positioning mechanisms are not convenient for achieving both overall movement of the moving base and precise deflection of hydrological equipment during use. Most can only adjust the position of the moving base or the deflection distance of the equipment, making it difficult to quickly cover multiple monitoring sections and resulting in low sampling efficiency.

[0004] Based on this, a hydrological cableway deflection positioning mechanism is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4 As shown, a hydrological cableway deflection positioning mechanism includes a movable base 1. Two cableway grooves 2 are opened on one side of the movable base 1. The cableway body 3 passes through the cableway grooves 2 on one side of the movable base 1. Protective shells 7 are provided on both sides of the outer side of the movable base 1. The bottom of the movable seat 1 is provided with a pulling mechanism 4, the outside of the pulling mechanism 4 is provided with a winding mechanism 9, and the two sides of the movable seat 1 and inside the protective shell 7 are provided with locking and positioning mechanisms 8.

[0023] In this embodiment, the overall movement of the moving seat 1 along the cableway and the precise deflection of the hydrological equipment are achieved through the drive mechanism and the deflection mechanism 4. The dual adjustment can cover a wider monitoring range and meet the requirements of multi-section sampling. The locking and positioning mechanism 8 uses rubber pads 87 for contact locking, which not only ensures the stability of the fixation but also avoids scratching the main body of the cableway 3. The winding mechanism 9 and the deflection mechanism 4 are integrated to realize the integrated operation of deflection and lifting of the hydrological equipment without the need for additional equipment, thus simplifying the process.

[0024] In one embodiment, such as Figure 2 and Figure 3As shown, the biasing mechanism 4 includes a biasing track 41, which is rotatably mounted on the bottom of the movable base 1. A mounting groove 42 is provided at the bottom of the biasing track 41, and a lead screw 43 is rotatably mounted inside the mounting groove 42 via a bearing. A first motor 44 is fixedly mounted at one end of the biasing track 41, and the lead screw 43 is driven by the first motor 44. A moving block 45 is threadedly connected to the outside of the lead screw 43. A second motor 5 is fixedly mounted inside the movable base 1, and the output end of the second motor 5 passes through the movable base 1 and is connected to the biasing track 41. An inspection door 6 is rotatably mounted on the top of the movable base 1 via a hinge. When precise biasing positioning is required, the movable base 1 is activated. The second motor 5 inside the base 1 has its output end passing through the movable base 1 and driving the bottom-mounted eccentric rail 41 to rotate, adjusting the angle of the eccentric rail 41 so that it faces the preset sampling point. Then, the first motor 44 at one end of the eccentric rail 41 is started. The first motor 44 drives the lead screw 43 in the mounting groove 42 at the bottom of the eccentric rail 41 to rotate. Since the moving block 45 connected to the external thread of the lead screw 43 slides in the mounting groove 42, the rotation of the lead screw 43 will drive the moving block 45 to move smoothly along the eccentric rail 41. The mounting bracket 91 fixed at the bottom of the moving block 45 moves along with it, and then drives the hydrological equipment to shift laterally through the rope 94, accurately reaching the top of the preset sampling point.

[0025] In one embodiment, such as Figure 2 and Figure 3 As shown, the winding mechanism 9 includes a mounting frame 91, which is fixedly installed with the moving block 45. A winding roller 92 is rotatably mounted inside the mounting frame 91 via bearings. A fourth motor 93 is provided on one side of the mounting frame 91, and the winding roller 92 is driven by the fourth motor 93. A rope 94 is provided outside the winding roller 92, and a hydrological device is provided at one end of the rope 94. When the fourth motor 93 of the winding mechanism 9 is started, the fourth motor 93 drives the winding roller 92 inside the mounting frame 91 to rotate. The winding roller 92 slowly releases the rope 94, lowering the hydrological device to a preset depth in the water body to complete the hydrological parameter measurement. After the measurement was completed, the fourth motor 93 was started in reverse to retrieve the hydrological equipment.

[0026] In one embodiment, such as Figure 2 and Figure 4As shown, the locking and positioning mechanism 8 includes two rotating parts 81, both of which are rotatably mounted on one side of the movable base 1 via bearings. Two fixed plates 82 are fixedly mounted on one side of the movable base 1, and a positive and negative screw 83 is rotatably mounted between the two fixed plates 82 via bearings. A third motor 84 is fixedly mounted on the bottom of one of the fixed plates 82, and the positive and negative screw 83 is driven by the third motor 84. Two sliders 85 are threaded onto the external surface of the positive and negative screw 83. Connecting rods 86 are rotatably mounted on one side of each slider 85 via pins. One end of each connecting rod 86 is connected to one of the two rotating parts 81 via pins. The rotating parts 81 are installed with rubber pads 87 on opposite sides, and the rubber pads 87 are adapted to the cableway body 3. Then, the third motor 84 of the locking and positioning mechanism 8 is activated. The third motor 84 drives the positive and negative screws 83 between the two fixed plates 82 to rotate. The two sliders 85 outside the positive and negative screws 83 move closer to each other as the screws rotate. The sliders 85 drive the connecting rod 86 to rotate through the pin. The connecting rod 86 pushes the rotating parts 81 to rotate around the bearing on one side of the moving seat 1, so that the rubber pads 87 on opposite sides of the two rotating parts 81 are tightly attached to the surface of the cableway body 3, and the moving seat 1 is firmly locked on the cableway body 3 to prevent displacement during monitoring.

[0027] The above embodiment discloses a hydrological cableway deflection positioning mechanism. First, the hydrological equipment is fixedly installed with one end of the rope 94 in the winding mechanism 9. The movable seat 1 is equipped with a drive mechanism. Activating the drive mechanism can drive the movable seat 1 to slide along the length direction of the cableway body 3 through the cableway grooves 2 on both sides, and initially move the entire mechanism to the approximate area of ​​the monitoring section. The drive mechanism adopts the existing mature technology solution of motor and roller transmission. The core function is to drive the roller to rotate through the motor, and with the help of the friction between the roller and the cableway body 3, drive the movable seat 1 to slide smoothly along the length direction of the cableway body 3. When precise positioning is required, the second motor 5 inside the movable base 1 is activated. The output end of the second motor 5 passes through the movable base 1 and drives the bottom-mounted tilting track 41 to rotate, adjusting the angle of the tilting track 41 so that it faces the preset sampling point. Then, the first motor 44 at one end of the tilting track 41 is activated. The first motor 44 drives the lead screw 43 in the mounting groove 42 at the bottom of the tilting track 41 to rotate. Since the moving block 45 connected to the external thread of the lead screw 43 slides in the mounting groove 42, the rotation of the lead screw 43 will drive the moving block 45 to move smoothly along the tilting track 41. The mounting bracket 91 fixed at the bottom of the moving block 45 moves along with it, and then the hydrological equipment is shifted laterally through the rope 94, accurately reaching the top of the preset sampling point. Then, the third motor 84 of the locking and positioning mechanism 8 is activated. The third motor 84 drives the positive and negative screws 83 between the two fixed plates 82 to rotate. The two sliders 85 outside the positive and negative screws 83 move closer to each other as the screws rotate. The sliders 85 drive the connecting rod 86 to rotate through the pin shaft. The connecting rod 86 pushes the rotating part 81 to rotate around the bearing on one side of the moving seat 1, so that the rubber pads 87 on the opposite side of the two rotating parts 81 are tightly attached to the surface of the cableway body 3, and the moving seat 1 is firmly locked on the cableway body 3 to prevent displacement during the monitoring process. Finally, the fourth motor 93 of the winding mechanism 9 is started. The fourth motor 93 drives the winding roller 92 inside the mounting frame 91 to rotate. The winding roller 92 slowly releases the rope 94, lowering the hydrological equipment to the preset depth in the water body to complete the hydrological parameter measurement. After the measurement is completed, the fourth motor 93 is started in reverse to retrieve the hydrological equipment, and the third motor 84 is started in reverse to unlock the mobile seat 1. The mobile seat 1 can then be moved along the cableway body 3 to the next monitoring point via the drive mechanism.
