Description

Technical Field

[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. When measuring water levels in the field of water conservancy projects, it is often necessary to use counterweights and water level measuring wire machines for measurement. When detecting the water level in the water area, a water level detection device is often required.

[0003] The Chinese patent announcement 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] The water level detection device used in the hydraulic project rotates the transmission rod to drive the threaded head to move so that the A stabilizing bar and the B stabilizing bar tend to a horizontal state from a vertical state, thereby increasing the contact area between the device and the silt in the water. However, the overall length is fixed. When measuring the water level of the hydraulic project, the measurable depth is limited, which is not convenient for depth detection. At the same time, floating debris on the water surface interferes with the detection and affects the detection effect. Utility Model Content

[0025] By setting a pull rope 209, the pull rope 209 is used to pull the counterweight block 205 to control the up and down movement of the counterweight block 205 in the water. When the counterweight block 205 sinks to the bottom, the excess pull rope 209 on the top will be stuck on the top of the floating block 208, and the movable counterweight block 205 will drive the connecting rope 211 to move, and the depth detection is performed by the reeled connecting rope 211.

[0026] See also Figure 3 A placement groove 210 is opened on the top of the support frame 1, and a pull-rope displacement sensor 207 is fixedly connected to the inner wall of the placement groove 210, and the output end of the pull-rope displacement sensor 207 is fixedly connected to the outer diameter of the connecting rope 211.

[0027] The sinking counterweight 205 drives the output end of the pull-rope displacement sensor 207 to move through the connecting rope 211, and the pull-rope displacement sensor 207 measures the sinking depth by pulling the length of the output end of the pull-rope displacement sensor 207.

[0028] See also Figure 3 A second winding post 204 is fixedly connected to the inner wall of the support frame 1 , and the outer diameter of the second winding post 204 is fixedly connected to the other end of the coil spring 206 , and a protective shell 201 is fixedly connected to the top of the support frame 1 .

[0029] One end of the coil spring 206 is fixed by setting a fixed second coiling column 204 , and the coil spring 206 is protected by setting a protective shell 201 .

[0030] See also Figure 3 The inner wall of the support frame 1 is rotatably connected to the first winding column 202 through a bearing, and the outer diameter of the first winding column 202 is fixedly connected to the other end of the pull rope 209. The rear end of the support frame 1 is fixedly connected to a servo motor 203, and the output end of the servo motor 203 passes through and is fixedly connected to the rear end of the first winding column 202.

[0031] The output end of the servo motor 203 drives the first winding column 202 to rotate, and the pull rope 209 with one end fixed to the outer diameter of the first winding column 202 is wound by the first winding column 202 .

[0032] See also Figure 4 The floating mechanism 3 includes a floating frame 301, which is fixedly connected to the outer wall of the support frame 1. The front and rear ends of the floating frame 301 are rotatably connected to the second movable block 305 through a pin shaft, and the left and right sides of the floating frame 301 are rotatably connected to the first movable block 303 through a pin shaft.

[0033] The floating frame 301 is provided to make the supporting frame 1 float on the water surface as a whole, and the movable first movable block 303 and the second movable block 305 are used to increase the contact between the whole and the water surface, thereby increasing the buoyancy.

[0034] See also Figure 4 The inner walls at both ends of the floating frame 301 are slidably connected to the second blocking net 304, and the inner walls at both sides of the floating frame 301 are slidably connected to the first blocking net 302.

[0035] By providing a movable first blocking net 302 and a second blocking net 304, the bottom of the floating frame 301 is surrounded all around to prevent floating objects from affecting the relaxed pull rope 209 and the connecting rope 211.

[0036] See also Figure 4 Both ends of the first movable block 303 and the second movable block 305 are fixedly connected with magnets 306, and two adjacent magnets 306 are magnetically attracted to each other.

[0037] By arranging uniformly distributed magnets 306 and utilizing the mutual magnetic attraction between the magnets 306 , the two first movable blocks 303 and the second movable blocks 305 that have returned to their original positions are limited to prevent any influence when the frame 1 is taken.

[0038] The working principle of the utility model is:

[0039] When the water level detector is measuring water, the output end of the servo motor 203 drives the first winding column 202 to rotate, and controls the pull rope 209 wound around the outer diameter of the first winding column 202 to loosen, so that the counterweight 205 drives the pull rope 209 to move downward. At the same time, the descending counterweight 205 drives the connecting rope 211 to move downward, and the connecting rope 211 drives the output end of the pull rope displacement sensor 207 and the coil spring 206 to move. When the counterweight 205 sinks to the bottom of the water, the connecting rope 211 stops pulling the pull rope displacement sensor 207. The output end of the sensor 207 and the coil spring 206 move, and hydraulic measurement is performed by moving the output end of the pull rope displacement sensor 207. The set floating block 208 is used to prevent the excess pull rope 209 from sinking into the water after rotation. The output end of the servo motor 203 drives the first winding column 202 to rotate, and the pull rope 209 is wound up, driving the counterweight block 205 to move upward. Without the pulling of the counterweight block 205, the reaction force of the coil spring 206 drives the connecting rope 211 to be wound around the outer diameter of the second winding column 204.

[0040] When the water level monitor is placed on the water surface, the first movable block 303 and the second movable block 305 which are magnetically attracted by the magnet 306 are separated, and the evenly distributed first movable block 303 and the second movable block 305 are flipped, and the first movable block 303 and the second movable block 305 are used to increase the overall buoyancy of the support frame 1, and the first blocking net 302 and the second blocking net 304 which slide downward are used to block impurities floating on the water surface to prevent impurities from being entangled in the pull rope 209 and the connecting rope 211, causing inaccurate measurement.
