Description

Technical Field

[0001] The utility model relates to the technical field of water level measurement, in particular to a water level measuring device for water conservancy projects. Background Art

[0002] Water level measurement primarily refers to the on-site measurement of water levels in rivers, lakes, and groundwater. Water level is the height of a body of water at a specific location above a standard base surface. Water level measurement data is required for the planning, design, construction, and management of water conservancy projects, as well as for the construction of bridges, ports, waterways, water supply and drainage projects. Water level measurement data is even more crucial in flood control and drought relief, serving as the basis for hydrological forecasts and hydrological intelligence. Steel water level gauges are highly effective instruments for accurately measuring water levels. They are commonly used to measure water levels in wells, boreholes, and water level pipes. They are particularly well-suited for observing groundwater levels in hydropower projects and for manual inspections of the infiltration line of earth-rockfill dams.

[0003] The more common water level measuring devices include an indicating instrument, a cable, and a water sensor fixed at the end of the cable. When in use, the water sensor is usually lowered through the cable along the water level hole, and the water surface position is judged according to the indicating instrument and the scale on the cable is read to measure the water level. However, when the cable is below, the speed is too fast, which will cause ripples on the water surface, affecting the underwater sensor, and it is difficult to control the retraction and extension of the cable, which may lead to inaccurate measurement results. When it is necessary to measure other positions in the water area, the device needs to be moved to the distance of the water area to control the measurement position, which makes the operation more cumbersome. Therefore, there is a need for a water level measuring device for water conservancy projects to solve this problem. Utility Model Content

[0027] In the present invention, the water level sensor used can be a sensor of the Shunlaida brand, model (SLDYB-2088). Example

[0028] See also Figure 1-4 The utility model provides a technical solution: a water level measuring device for water conservancy projects, including a placing frame 1, a mounting frame 2 is fixedly installed on the top of the inner side of the placing frame 1, a first pulley 3 is rotatably installed on the inner side of the mounting frame 2, a pressing and releasing mechanism 4 is provided on the inner side of the placing frame 1, and a telescopic fixing mechanism 5 is provided on the outside of the pressing and releasing mechanism 4.

The elastic rods 44 are L-shaped, there are two groups of them, and they are symmetrically distributed on both sides inside the fixing plate 41, which facilitates the fixation of the left ratchet 43.

[0032] Furthermore, a water level sensor 6 is fixedly mounted on one end of the mounting rod 411 away from the placement rack 1 to facilitate measurement of the water level depth. Example

[0033] See also Figure 5-6 , and combined with the first embodiment, it is further obtained that the telescopic assembly 51 includes a first telescopic rod 511, the first telescopic rod 511 is fixedly installed on the outside of the mounting rod 411, a rack 512 is fixedly installed on the inside of the first telescopic rod 511, a second telescopic rod 513 is slidably installed on the outside of the rack 512, a connecting plate 514 is fixedly installed on the inside of the second telescopic rod 513, a gear 515 is rotatably installed inside the connecting plate 514, and the gear 515 is meshed with the rack 512, and the moving rod 51 is slidably installed inside the second telescopic rod 513. 6. A limiting hole 518 is provided at the top of the moving rod 516. A bidirectional rack 517 is fixedly installed at one end of the moving rod 516 close to the second telescopic rod 513, and the bidirectional rack 517 extends from one end inside the first telescopic rod 511 and is meshed with the gear 515. A mounting plate 519 is fixedly installed at one end of the moving rod 516 away from the second telescopic rod 513, and a second pulley 5110 is rotatably installed on the outside of the mounting plate 519, and the second pulley 5110 is rotatably connected to the measuring rope 410, so as to facilitate adjustment when controlling the depth of different waters.

[0034] Furthermore, the fixing assembly 52 includes a support block 521, which is fixedly installed on the outside of the second telescopic rod 513, and a pressing plate 523 is rotatably installed on the inner side of the support block 521.

The pressing plate 523 extends to one end of the outside of the support block 521 and is fixedly installed with a limiting rod 524, and the limiting rod 524 is slidably connected to the limiting hole 518, so as to facilitate fixing the movable rod 516 of appropriate length to prevent deviation and affect the measurement data.

[0035] Furthermore, there are two groups of gears 515 symmetrically distributed on both sides of the bidirectional rack 517 , so as to facilitate the meshing movement of the second telescopic rod and the movable rod.

[0036] Furthermore, the number of the limiting holes 518 is four groups, and they are evenly distributed outside the moving rod 516, so as to facilitate the control of the length of the fixed moving rod 516.

[0037] In actual operation, when the device is used, the device is first moved to the vicinity of the test water area. By pulling the second telescopic rod 513, the second telescopic rod 513 drives the gear 515 on the connecting plate 514 to engage and move on the rack 512 inside the first telescopic rod 511. When the test area is far away from the device, the limiting hole 518 is pulled again, so that the limiting hole 518 drives the bidirectional rack 517 inside the second telescopic rod 513 to engage and move along the two sets of gears 515. The movement causes the moving rod 516 to move toward the measuring water area. When it reaches the appropriate position, the end of the pressing plate 523 is pressed, causing the pressing plate 523 to move toward the support block 521 and squeeze the second spring 522, so that the pressing plate 523 extends to the outside of the support block 521. The limiting rod 524 on one end is lifted along both sides of the support block 521, and then the limiting rod 524 is aligned with the limiting hole 518 and is released, so that the limiting rod 524 is fixed with the limiting hole 518, allowing the moving rod 516 to lengthen. The degree is maintained to prevent deviation, and then the mounting plate 519 is aligned with the target test water area. Then, the turning handle 49 is pushed to squeeze the roller 48, so that the roller 48 pushes the left ratchet 43 inside the fixing plate 41 to move toward the inside of the fixing plate 41. When the left ratchet 43 moves, the limit block 46 squeezes the elastic rod 44, so that the elastic rod 44 slides along the extrusion groove 45 until the elastic rod 44 hits the V-shaped position of the limit block 46, thereby fixing the left ratchet 43 and making the right The ratchet 47 disengages from the left ratchet 43, so that the right ratchet 47 and the measuring rope 410 on the roller 48 can be retracted and released by turning the handle 49. Then, the measuring rope 410 is paid out along the first pulley 3 and the second pulley 5110 by rotating the handle 49, so that the water level sensor 6 at one end of the measuring rope 410 slowly enters the target water area to prevent it from entering quickly and generating water waves that affect the detection instrument. Then, the water level is measured by detecting the water pressure to obtain the depth.
