DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] like Figure 1 and Figure 2As shown, a flood control water level warning device includes a support tube 10, a controller 11 is fixedly installed on the top wall of the support tube 10, an alarm 12 is fixedly installed on the top wall of the controller 11, a sensing device for sensing the water level is arranged on the side wall of the support tube 10, the sensing device includes multiple air bags 17, and an alarm device is arranged on the top wall of the support tube 10, the alarm device includes a sensing element 22.

[0028] It is worth noting that the support tube 10 and the controller 11 are both prior art and have been disclosed in a flood control water level meter (202320624921.X), which will not be elaborated here.

[0029] During specific use, the sensing device can sense the water level. When it is sensed that the water level exceeds a certain amount, an alarm can be sounded through the alarm device.

[0030] To sum up, by setting up a sensing device and an alarm device, the water level can be sensed by the sensing device. When the water level exceeds a certain amount, the alarm device can be activated to alarm. Compared with the prior art, it is easy to use and has a simple structure.

[0031] like Figure 3 As shown, a limit ring 14 is fixedly installed at the upper position of the side wall of the support tube 10, a water level ring 13 is sleeved at the lower position of the side wall of the support tube 10, and multiple air bags 17 are fixedly installed on the side wall of the water level ring 13 in a circular array.

[0032] Two first springs 16 are fixedly installed between the top wall of the water level ring 13 and the bottom wall of the limiting ring 14 , and two trigger rods 15 are fixedly installed on the top wall of the water level ring 13 . The two trigger rods 15 are respectively located in the corresponding first spring 16 cavities, and the two trigger rods 15 pass through the limiting ring 14 .

[0033] The two trigger rods 15 are movably connected to the penetration point of the limiting ring 14, and the top wall surfaces of the two trigger rods 15 are both in an inclined state from low to high, from approaching each other to moving away from each other.

[0034] During specific use, the airbag 17 can float on the water surface due to its characteristics. When the water level rises, the water level ring 13 can be driven to move upward by the airbag 17, and the movement of the water level ring 13 can drive the trigger rod 15 to move upward. When the trigger rod 15 moves to the corresponding position, the alarm device can be automatically triggered to alarm. The specific triggering method will be discussed below. The limit ring 14 can limit the trigger rod 15. Because the water level ring 13 and the trigger rod 15 are fixedly connected, the limit ring 14 can make the water level ring 13 move smoothly to prevent shaking due to water sources and other reasons, which affects the measurement of the water level. The first spring 16 can also limit the limit ring 14. When the water level becomes low, the water level ring 13 can be pushed to move downward, so that the water level ring 13 and the airbag 17 can always be located on the water surface.

[0035] To summarize, by setting the limit ring 14, the trigger rod 15, the first spring 16, the airbag 17 and the water level ring 13, the water level ring 13 can be always kept on the water surface by the airbag 17 and the first spring 16, so as to measure the water level. When the water level ring 13 moves up and down according to the water level, it can drive the trigger rod 15 to move up and down. When the trigger rod 15 moves to the corresponding position, it can trigger the alarm device to sound an alarm.

[0036] like Figure 4 and Figure 5 As shown, a protective shell 18 is installed on the top wall of the support tube 10 at the left and right sides of the controller 11, the bottom wall and the left and right side walls of the protective shell 18 are hollow, and a through hole 19 is opened on the front and rear side walls of the two protective shells 18.

[0037] A displacement plate 20 is provided in the cavity of the two protective shells 18, and a connecting plate 24 is fixedly installed on the front and rear side walls of the two displacement plates 20. A limit plate 21 is fixedly installed on the ends of the two connecting plates 24 that are away from each other. The two connecting plates 24 are movably connected to the corresponding through holes 19, and the two limit plates 21 are respectively located on the front and rear side walls of the protective shell 18.

[0038] At one end of the two protective shells 18 that are close to each other, a side plate 26 is fixedly installed on both the front and rear side walls, and a second spring 25 is fixedly installed between the side walls of the two sets of side plates 26 that are away from each other and the corresponding limit plates 21.

[0039] A sensing element 22 is fixedly installed on the side wall of the two displacement plates 20 that are close to each other, and a bottom plate 23 is fixedly installed on the bottom wall of the two displacement plates 20. The bottom walls of the two bottom plates 23 are inclined from low to high from close to each other to far away from each other, and the bottom wall of the bottom plate 23 is in contact with the top wall of the trigger rod 15.

[0040] In specific use, when the trigger rod 15 moves upward, the two bottom plates 23 can be moved to positions close to each other according to its inclined surface and the inclined surface of the bottom plate 23. When the two bottom plates 23 move to positions close to each other, the two displacement plates 20 can be driven to move to positions close to each other. When the two displacement plates 20 move to positions close to each other, the two sensing members 22 can be driven to move to positions close to each other. When the two sensing members 22 contact the controller 11, an electrical signal can be transmitted to the controller 11, and then the controller 11 can activate the alarm 12 to sound an alarm. When the trigger rod 15 moves downward, the two sets of limit plates 21 can be moved to positions away from each other by the force of the second spring 25. The limit plate 21 can drive the two displacement plates 20 to move to positions away from each other through the connecting plate 24, so as to reset the sensing member 22 and the bottom plate 23, which is convenient for the next use. When the sensing member 22 is separated from the alarm 12, the alarm can be automatically canceled.

[0041] In summary, by providing the protective shell 18, the perforation 19, the displacement plate 20, the limit plate 21, the sensor 22, the bottom plate 23, the connecting plate 24, the second spring 25 and the side plate 26, the alarm device can be triggered by moving the trigger rod 15 upward. When the water level drops, the alarm can be automatically canceled and the structure can be automatically reset. The protective shell 18 protects the sensor 22 and the controller 11. It is easy to use and has a simple structure.
