[0042] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned direction words are not used to limit the present invention. Specific embodiment 1

[0044] See also Figure 1-7 The utility model is a water level warning device for a water conservancy project, comprising a base 1, with several limit rods 2 fixed on the upper surface of the base 1; an early warning rod 3 is fixed on the upper surface of the base 1, and a warning rod 4 is fixed on the upper surface of the base 1; a floating plate 5 is sleeved on the outer sides of the limit rod 2, the early warning rod 3 and the warning rod 4; a plurality of placement openings 6 are opened on the surface of the floating plate 5; a bracket 7 is fixed inside the early warning rod 3, a baffle 8 is fixed inside the bracket 7, and a through hole 9 is opened inside the baffle 8; an adjusting rod 10 passes through the inside of the baffle 8, a movable plate 11 is fixed at one end of the adjusting rod 10, and a fixed plate 12 is fixed on one side of the movable plate 11; a clamping rod 13 is fixed at one end of the movable plate 11; an extrusion plate 14 is fixed at the end of the adjusting rod 10 away from the movable plate 11, and a plurality of pressure sensors 15 are fixed on the inner wall of the early warning rod 3; a spring 16 is fixed between the movable plate 11 and the baffle 8.

[0045] Specifically, a positioning hole 17 is opened on the surface of the fixing plate 12; a plurality of tension springs 18 are fixed to the outside of the warning rod 3, a handle 19 is fixed to one end of the tension spring 18, and a positioning rod 20 is fixed to one end of the handle 19.

[0046] Furthermore, the positioning rod 20 passes through the warning rod 3, and one end of the positioning rod 20 contacts the surface of the fixed plate 12; an adjustment groove 21 is opened on one side of the placement opening 6 that is slidably connected to the warning rod 3, and the inner wall of the adjustment groove 21 matches the handle 19; the card rod 13 passes through the warning rod 3, and one end of the card rod 13 is a hemispherical structure; a guide groove 22 is opened on one side of the placement opening 6 that is slidably connected to the warning rod 3, and the inner wall of the guide groove 22 is an arc-shaped structure.

[0047] When the water level drops to 0, the buoyancy indicator 22 will be turned off, and the floating plate 5 will be lifted up. When the floating plate 5 moves upward, the floating plate 5 will move to the position of a clamping rod 13, and the clamping rod 13 will be squeezed by the inner wall of the placement port 6. The guide groove 22 facilitates the clamping rod 13 to pass through the placement port 6. At this time, the hemispherical clamping rod 13 is pushed by the inner wall of the placement port 6, and the other end of the clamping rod 13 pushes the movable plate 11 to move in the direction of the baffle 8. The movable plate 11 drives the squeezing plate 14 to squeeze the pressure sensor 15 on the inner wall of the warning rod 3. After the pressure sensor 15 is pressurized, the signal is transmitted to the single chip microcomputer 27, and the single chip microcomputer 27 transmits the signal to the warning light 26. The warning light 26 lights up, which plays a warning role. When the floating plate 5 continues to move upward, multiple pressure sensors 15 transmit signals to the single chip microcomputer 27, and the single chip microcomputer 27 controls the brightness of the warning light 26 to become brighter, thereby improving the warning effect. At the same time, during the movement of the movable plate 11, one side of it The fixed plate 12 moves accordingly, and when the positioning hole 17 on the surface of the movable plate 12 moves to one end of the positioning rod 20, under the action of the tension spring 18, one end of the positioning rod 20 is stuck in the positioning hole 17, thereby preventing the extrusion plate 14 from resetting, so that the extrusion plate 14 continues to press the pressure sensor 15, so that the warning light 26 remains on. When the device needs to be reset, the staff pulls several handles 19 outward. At this time, the positioning rod 20 is pulled out of the positioning hole 17. Under the action of the spring 16, the clamping rod 13 and the extrusion plate 14 are reset, the pressure sensor 15 loses pressure, and the warning light 26 goes out. The device can adjust the brightness or color of the warning light according to the water level of the monitoring position, so as to achieve the early warning effect, and placing the adjusting rod 10, extrusion plate 14, pressure sensor 15 and other structures inside the early warning rod 3 also reduces the influence of the external environment on the device, avoids false alarms, inaccurate forecasts, etc., so that the staff can better understand the water level situation.
