Technical Field

[0001] The utility model relates to the technical field of hydrological measurement, in particular to an adjustable bracket for hydrological measurement. Background Art

[0002] Hydrography is a specialized surveying technique used to study the physical properties of water bodies, their distribution, and their flow patterns on the Earth's surface. It encompasses depth detection, flow velocity measurement, riverbed morphology characterization, and water quality analysis for bodies of water such as rivers, lakes, and oceans. Using tools and techniques such as sonar, radar, satellite remote sensing, and traditional sounding rods, hydrography provides fundamental data support for flood warning, water resource management, waterway maintenance, and environmental monitoring. Furthermore, hydrography plays a crucial role in understanding the impact of climate change on the water cycle, making it an indispensable research tool across diverse disciplines, including hydrology, geography, and environmental science.

[0003] Existing hydrographic survey supports often require manual height and angle adjustment, which is not only time-consuming and labor-intensive, but also becomes even more difficult to operate in inclement weather or emergency situations, thus compromising measurement efficiency. Furthermore, existing support systems often fail to respond quickly to changing hydrological conditions, such as rapid changes in water levels, preventing the acquisition of critical data in real time. Utility Model Content

DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0018] Example:

[0019] An adjustable bracket for hydrological measurement, such as Figure 1-Figure 4 As shown, it includes a fixed frame 1, a sliding frame 2, a connecting block 3, a slide rail 4, a slider 6, a floating assembly, a first winding frame 12, a second winding frame 13, a fixed block 14 and a pull rope 15. The fixed frame 1 is fixed to the shore. The top of the fixed frame 1 is fixedly connected to the sliding frame 2. A slide groove is opened on the left side of the sliding frame 2. The connecting block 3 is slidably connected in the slide groove. The left side of the connecting block 3 is fixedly connected to the slide rail 4. The slide rail 4 is slidably connected to the slider 6. The side of the slider 6 away from the sliding frame 2 is connected to the floating assembly. The top right side of the slider 6 is fixedly connected to the first winding frame 12. The top left side of the slide rail 4 is fixedly connected to the second winding frame 13. The front side of the second winding frame 13 is fixedly connected to a handwheel. The second winding frame 13 is provided with a self-locking function. A pull rope 15 is installed between the fixed block 14, the first winding frame 12 and the second winding frame 13.

[0020] Initially, the slider 6 is in contact with the connecting block 3, the pull rope 15 is in a free state, the return spring 17 is in a normal state, and the second winding frame 13 is in a locked state. When hydrological measurement of the water environment is required, the detection equipment is first installed in the floating assembly, and then the fixed frame 1 is fixedly installed on the shore, so that the slide rail 4 is located above the water surface close to the shore, so that the detection equipment in the floating assembly can detect the water surface. When the weeds on the shore block the detection equipment, the second winding frame 13 is unlocked, and the second winding frame 13 is rotated by the handwheel so that the pull rope 15 is tightened and wound on the second winding frame 13. During this process, the pull rope 15 pulls the fixed block 14 to move it to the left away from the connecting block 3, the return spring 17 is compressed, and then the second winding frame 13 is locked, thereby moving the floating assembly away from the weeds on the shore, so that the detection equipment is located above the water surface away from the shore, preventing the shore weeds from affecting the hydrological measurement results, and the entire operation only needs to be performed on shore, which is convenient to operate.

[0021] like Figure 3As shown, a return spring 17 is also included. Two return springs 17 are fixedly connected between the slide rail 4 and the slider 6. The two return springs 17 are respectively located on the front and rear sides of the slide rail 4. The return springs 17 are configured as coil springs. The weight of the floating assembly and the detection equipment thereon are both light, and the total weight of the floating assembly and the detection equipment thereon is less than the elastic force of the return spring 17. When the detection equipment needs to be retracted for maintenance, the second winding frame 13 is unlocked, and the return spring 17 returns to its original state. Under the elastic force of the return spring 17, the slider 6 slides close to the connecting block 3. The slider 6 pulls the pull rope 15 to reset through the fixed block 14. The second winding frame 13 rotates to release the pull rope 15. When the slider 6 is reset, the second winding frame 13 is locked, and the detection equipment on the floating assembly can be removed. There is no need to manually pull the slider 6 to reset. Therefore, the sliding distance of the slider 6 can be adjusted at will according to the specific use environment, further facilitating the use of the adjustable bracket.

[0022] like Figure 1-Figure 4 As shown, the floating assembly includes a floating block 5, a mounting plate 61, a guide cylinder 7, a floating rod 8, a floating ball 10 and a mounting block 11. The bottom of the slide rail 4 and the slider 6 are fixedly connected to two floating blocks 5. The sliding friction between the connecting block 3 and the sliding frame 2 is greater than the force of the waves, which prevents the floating block 5 from driving the connecting block 3 to rise due to the impact of the waves. The side of the slider 6 away from the sliding frame 2 is fixedly connected to the mounting plate 61. The middle of the mounting plate 61 is slidably connected to the guide cylinder 7, which passes through the mounting plate 61. A guide hole is provided in the middle of the guide cylinder 7, in which a floating rod 8 is slidably connected, a float ball 10 is fixedly connected to the bottom of the floating rod 8, and a mounting block 11 is fixedly connected to the top of the floating rod 8. Mounting holes for installing the detection equipment are provided on the mounting plate 61 and the mounting block 11. A through hole 9 is provided on the floating rod 8, and the through hole 9 passes through the float ball 10. The sliding friction between the connecting block 3 and the sliding frame 2 is less than the total weight of the parts on the connecting block 3, thereby ensuring that the bottom of the floating block 5 and the bottom of the float ball 10 are in contact with the horizontal plane.

[0023] After adjusting the position of the floating assembly, the bottom of the float 10 and the bottom of the float block 5 are in contact with the horizontal plane. Under the buoyancy of the float 10 and the float block 5, the floating rod 8 slides upward along the guide cylinder 7. When the horizontal plane rises, the connecting block 3 can slide upward along the slide groove of the sliding frame 2 through the float block 5 as the horizontal plane rises, preventing the slide rail 4 and the slider 6 from being immersed in water. When the horizontal plane drops, the float block 5 and the float 10 both move downward as the horizontal plane drops, so that the height of the connecting block 3 can be automatically adjusted as the horizontal plane rises or drops, further facilitating the use of this adjustable bracket.

[0024] like Figure 1As shown, a foldable cover cloth 16 is also included. The cover cloth 16 is connected between the connecting block 3 and the sliding frame 2 and is located in the chute of the sliding frame 2. The cover cloth 16 can block the chute on the sliding frame 2 to prevent foreign objects from entering the chute or water from rusting, which would cause a significant change in the friction between the connecting block 3 and the sliding frame 2.

In addition, it should be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
