Description

Technical Field

[0001] The utility model relates to the technical field of water level detection, in particular to a water level depth measuring instrument. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. In water conservancy projects, it is often necessary to measure the water level, which is conducive to the development of water conservancy projects.

[0003] The Chinese patent publication number is: CN216483320U, which discloses a water level detection device for water conservancy projects. The application states: "After long-term use, the existing water level detection device may tilt under the impact of the water flow, resulting in detection errors. Moreover, when the existing detection device is used for a long time, the surface of the instrument is easily covered by outdoor dust, resulting in greater errors in the data of the detection device." Although the application solves this problem, it has the following defects:

[0004] During use of the water level monitoring device for water conservancy projects, the A and B stabilizing bars are controlled to move parallel to the ground by rotating the transmission rod, thereby increasing the contact area with the ground. However, the length of the water level monitoring device for water conservancy projects is fixed and cannot be extended, resulting in a small range for measuring water levels, making it difficult to measure water levels at deep depths, and difficult to tidy up the A and B stabilizing bars after they are unfolded. At the same time, after using the water level monitoring device for water conservancy projects, the water-entering structure cannot be effectively cleaned, and the water-entering structure is easily entangled with aquatic plants and other residues, causing the residues to corrode the water-entering structure and reducing the use time.

By sliding the H-shaped block, it is convenient to slide the movable shell, and the winding connecting rope can be arranged, which solves the problem that the water level depth measuring instrument is not long enough, resulting in a small water level measurement range.

[0016] 2. The water level depth measuring instrument controls the movable connecting rope to return to its original position during collection through the provided guide plate. The provided scraper cleans the water plants on the shrinking connecting rope. The reaction force of the second springs on both sides pushes the movable block so that the two movable sleeves clamp the connecting rope, thereby reducing the residual moisture on the connecting rope, preventing the residue on the connecting rope from corroding the connecting rope, and reducing the use time of the connecting rope.

The movable column 202 controls the connecting rope 211 to extend and retract through the connecting tube 213, so that the connecting rope 211 moves with the conical block 212. The movable shell 201 can drive the limiting plate 204, the connecting plate 205 and the connecting tube 213 to move, exposing the wound connecting rope 211, which is convenient for arranging the connecting rope 211.

The connecting plate 205 and the inner wall of the shell 1 are slidably connected with the same collecting box 203, which is engaged with the block 214 through the groove on the left side of the movable column 202, so that the output end of the servo motor 4 drives the connecting tube 213 to rotate through the movable column 202, and the collecting box 203 can collect water drops dripping from the connecting rope 211.

[0032] See also Figure 5 A guide plate 302 is fixedly connected to the inner wall of the mounting groove 301, and a scraper 303 is fixedly connected to the top of the guide plate 302.

[0033] The working principle of the utility model is:

[0034] After the water level depth measuring instrument is fixed, the servo motor 4 is started, and the output end of the servo motor 4 drives the connecting pipe 213 to rotate through the movable column 202, so that the wound connecting rope 211 and the movable end of the pull rope displacement sensor 210 are driven to sink to the bottom of the water through the conical block 212. With the movement of the conical block 212, the pull rope displacement sensor 210 can measure the distance from the water surface to the bottom of the water. When shrinking, the servo motor 4 is controlled to rotate in the opposite direction, and the connecting rope 211 in the water is shrunk and wound by rotating the movable column 202. The shrinking connecting rope 211 adjusts the movable angle through the set guide plate 302, and the debris attached to the outer diameter of the connecting rope 21 is removed from the connecting rope 21 through the set scraper 303. Excess debris on the rope 211 is intercepted, and the reaction force of the second spring 304 pushes the two movable blocks 306 to squeeze the connecting rope 211. The rotatable movable sleeve 305 is convenient for intercepting most of the water source when the connecting rope 211 moves. The wound connecting rope 211 is gathered together. Because it is wet, water will drop into the collecting box 203. The H-shaped block 207 is pressed to apply pressure to the first spring 208, so that the movable shell 201 can drive the limiting plate 204 and the connecting plate 205 to move to the left, so that the connecting rope 211 can be exposed to the sun and the water in the connecting rope 211 can be evaporated. According to the direction of sunlight, the movement of the movable shell 201 on the limiting plate 204 and the connecting plate 205 is controlled.
