Description

Technical Field

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

[0002] Water conservancy projects are an engineering field that uses water resources for planning, construction, and management. The design and construction of water conservancy projects require comprehensive consideration of multiple factors such as geology, hydrology, and hydraulics to ensure the safety, reliability, and maximum benefits of the projects. During the construction of water conservancy projects, a water level detection device needs to be set up to conduct real-time detection of the water level in the river.

[0003] Generally, water level detection devices use a water gauge, which stands at the bottom of the river. There are scales on the surface of the water gauge. When the staff needs to check the water level, they only need to read the liquid surface height and the scale on the water gauge to know the water level. However, the above-mentioned water gauge detection method requires the staff to check constantly, which is more dependent on manual labor. At the same time, if the water level rises at night, the staff cannot be reminded in the first time, thereby reducing the practicality of the water level detection device.

[0004] Therefore, in response to the above problems, we need to propose a water level detection device for water conservancy project management. Utility Model Content

[0005] The purpose of the utility model is to provide a water level detection device for water conservancy project management to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a water level detection device for water conservancy project management, including a water gauge, and also including:

[0007] A scale is arranged on the surface of the water gauge, a cover plate is arranged on the top of the water gauge, and a water inlet hole is opened at the bottom of the water gauge surface;

[0008] A connecting shell is fixedly connected to the top of the inner cavity of the water gauge, a positioning plate is fixedly connected to the top of the inner cavity of the water gauge, and a pressure sensor is fixedly connected to the top of the inner cavity of the connecting shell.

[0009] Preferably, the front and rear sides of the inner cavity of the water gauge are fixedly connected with sliding rods, a connecting rod is movably connected between the surfaces of the two sliding rods, and a buoy is provided at the bottom of the connecting rod.

[0010] Preferably, positioning blocks are fixedly connected to both sides of the connecting rod, and the bottom of the positioning blocks is fixedly connected to the buoy.

[0011] Preferably, springs are fixedly connected to both sides of the bottom of the inner cavity of the connecting shell, and a movable plate is fixedly connected between the tops of the two springs.

[0012] Preferably, an extrusion block is fixedly connected to the top of the movable plate, and the extrusion block is located directly below the pressure sensor.

[0013] Preferably, the inner cavity of the positioning plate is movably connected to a limiting sleeve, the inner cavity of the limiting sleeve is slidably connected to an abutment rod, and the bottom of the abutment rod is fixedly connected to the connecting rod.

[0014] Preferably, a retaining ring is sleeved on the bottom of the abutment rod surface, and the bottom of the retaining ring is fixedly connected to the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model can change the position of the float in real time according to the height of the water level through the float, connecting rod, abutment rod, movable plate, extrusion block and pressure sensor. When the water level is high, the float will drive the abutment rod to move upward, and then the movable plate will be squeezed to squeeze the pressure sensor through the extrusion block. The pressure sensor can then sound an alarm in the first time to remind the staff to deal with it in time, avoiding the failure to remind the staff in the first time when the water level rises at night.

The buoy 13 is located at the bottom of the connecting rod 12, and its function is to float on the water surface to monitor the river water level in real time.

[0027] Positioning blocks 14 are fixedly connected to both sides of the connecting rod 12 . The bottom of the positioning block 14 is fixedly connected to the buoy 13 . The positioning block 14 is located on one side of the connecting rod 12 and its function is to position the buoy 13 .

[0028] Springs 8 are fixedly connected to both sides of the bottom of the inner cavity of the connecting shell 5, and a movable plate 7 is fixedly connected between the tops of the two springs 8. The springs 8 and the movable plate 7 are located at the bottom of the inner cavity of the connecting shell 5, and their function is to buffer the impact force of the abutting rod 15.

The buoy 13 will float on the water surface, and the two slide bars 11 will limit the buoy 13 through the connecting rod 12. When the river water rises, the buoy 13 will use the buoyancy to push up the abutment rod 15 on the top of the connecting rod 12. At this time, the abutment rod 15 will be squeezed toward the upper movable plate 7 through the limiting sleeve 10. After being squeezed, the movable plate 7 will drive the squeezing block 16 to push up.
