[0002] Water level refers to the elevation of the free water surface relative to a certain base surface, and the distance between the water surface and the river bottom is called the water depth. The base surface used to calculate the water level can be a certain characteristic sea level elevation as the zero-point leveling base surface, called the absolute base surface, and the Yellow Sea base surface is commonly used; or the elevation of a specific point can be used as a reference to calculate the zero point of the water level, called the station base surface. The water level is the most intuitive factor reflecting the water conditions of the water body, and its changes are mainly caused by the increase or decrease of the water volume in the water body. The water level process line is a curve showing the change of water level at a certain place over time. The horizontal coordinate is time and the vertical coordinate is water level. The wireless water level detection sensor is a common tool used to detect the water level, which is usually used in conjunction with a water level meter.

[0003] There are many kinds of existing wireless water level detection sensors, some of which need to be placed below the water level. Such water level sensors need to be pulled out using a pull rope, etc., otherwise the water level sensor may be lost, which is time-consuming and laborious to find. If a split connection is used, at least two fixed points need to be set up, one for fixing the water level meter and the other for fixing the pull rope connected to the water level sensor. This is inconvenient to install, and the space in some waters is limited, so multiple devices cannot be installed.

[0023] The water level meter 2 is installed above the water surface, the wireless water level sensor 1 is connected to the water level meter 2 through a wireless signal, the connection box 3 is installed on one side of the water level meter 2, the side of the connection box 3 is open, and the cover plate 4 is installed at the opening. The cover plate 4 can be pulled out from the inside of the connection box 3 through the fin plate 5, which is convenient for arranging the pull rope 6 and the wireless water level detection sensor inside the connection box 3. The fin plate 5 is stuck in the inside of the connection box 3 to facilitate the fixation of the cover plate 4. The pull rope 6 can be put into the water with the wireless water level detection sensor, and the through hole 7 can facilitate the wireless water level detection sensor to pass through. The winding component can facilitate the pull rope 6 to be rolled up on it, and the locking component can make the pull rope 6 retractable and the length of the connection box 3 is fixed, and the pull rope 6 will not drop too much.

[0024] In one embodiment, specifically, the winding assembly includes a rotating shaft 8 connected between the two fin plates 5 by a spring, and connecting plates 9 are respectively fixedly connected on both sides of the rotating shaft 8. A plurality of connecting rods 10 are arranged between the two connecting plates 9, and the pull rope 6 is wound around the outside of the plurality of connecting rods 10. The connecting plate 9 is cross-shaped, and four slide grooves 15 are respectively arranged on the opposite sides of the two connecting plates 9. The connecting rod 10 is slidably connected to the slide grooves 15 on the two connecting plates 9, and sliders 16 are respectively connected to the two ends of the connecting rod 10. The slider 16 and the slide groove 15 Sliding connection, a spring 17 is provided inside the slide groove 15, and the spring 17 is located on one side of the slider 16. The rotating shaft 8 can rotate the multiple connecting rods 10 between the two connecting plates 9. One end of the pull rope 6 is fixedly connected to one of the connecting rods 10 to facilitate the winding of the pull rope 6. The slide groove 15 can change the distance between the connecting rod 10 and the rotating shaft 8, and it is convenient to adjust the circumference of the quadrilateral formed by the four connecting rods 10, and can adapt to pull ropes 6 of different lengths. The spring 17 and the slider 16 can keep the connecting rod 10 in a tensioned state to avoid the pull rope 6 from being messy inside the connection box 3.

[0025] Among them, the locking assembly includes a pressure plate 11 hinged at the bottom of the through hole 7, a protrusion 12 is provided on the pressure plate 11, a depression 13 matching the protrusion 12 is provided at the bottom of the connecting box 3, and a paddle 14 is provided on one side of the bottom of the pressure plate 11.

Since the pressure plate 11 is connected by a torsion spring, the resistance when the pull rope 6 is pulled down is small. When the pull rope 6 is loosened, the pull rope 6 will be resisted by the pressure plate 11 and will not continue to move down. When the length of the pull rope 6 that needs to be extended out of the connection box 3 is too long, the multiple connecting rods 10 can be retracted. At this time, the perimeter of the quadrilateral formed by the four connecting rods 10 will be reduced, and the excessively long pull rope 6 can also be wrapped around the outside of the four connecting rods 10, so that a sufficiently long pull rope 6 can be stored to facilitate the detection of deeper water levels.

[0028] In one embodiment, specifically, a guide wheel 19 is installed inside the connection box 3 and above the through hole 7 , and the guide wheel 19 can guide the pull rope 6 to prevent other structures in the connection box 3 from interfering with the movement of the pull rope 6 .
