[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A water level detection and alarm device for flood early warning includes a water level detection cylinder 1. Three liquid level tubes 2 are provided on the side wall of the water level detection cylinder 1. The three liquid level tubes 2 have different lengths and heights. A liquid storage tank 3 is provided at one end of the liquid level tube 2. An automatic alarm mechanism 4 is provided inside the liquid storage tank 3. A liquid inlet stabilization component 5 is provided inside the water level detection cylinder 1. A mounting component 6 is provided at the bottom of the water level detection cylinder 1.

[0031] The automatic alarm mechanism 4 includes a float 401, a guide cylinder 402, a slide rod 403, a touch head 404, a touch switch 405 and an audible and visual alarm 406. The float 401 is arranged inside the liquid storage tank 3, the guide cylinder 402 is fixedly connected to the bottom of the liquid storage tank 3, the slide rod 403 is movably arranged inside the guide cylinder 402, the top of the slide rod 403 is fixedly connected to the float 401, the touch head 404 is arranged on the top of the float 401, the touch switch 405 is arranged on the top of the liquid storage tank 3, the audible and visual alarm 406 is installed on the top of the liquid storage tank 3, and the audible and visual alarm 406 is electrically connected to the touch switch 405.

[0032] Specifically, such as Figure 5 As shown, the mounting assembly 6 includes mounting feet 701, a base 702 and a spiral ground plug 703. Multiple mounting feet 701 are fixedly connected to the bottom of the water level detection cylinder 1, the base 702 is fixedly connected to the bottom of the mounting feet 701, and the spiral ground plug 703 is arranged in the middle of the base 702. The spiral ground plug 703 is threadedly connected to the base 702.

[0033] Specifically, such as Figure 4 As shown, a protective tube 14 is fixedly connected to the inner wall of the liquid storage tank 3 , and the float 401 is located inside the protective tube 14 .

[0034] Specifically, such as Figure 4 As shown, a magnetic block 15 is installed on the top of the float 401, and a magnetic block 2 16 is installed on the inner wall of the liquid storage tank 3. The magnetic block 15 and the magnetic block 2 16 are magnetically matched.

[0035] Specifically, such as Figure 4 As shown, reinforcement strips 17 are installed between the plurality of mounting feet 701 .

[0036] When the flood level rises, water will enter the water level detection cylinder 1 through these liquid level tubes 2. Since the top of the water level detection cylinder 1 is open, the flood entering the water level detection cylinder 1 is at the same liquid level as the external flood. Since the heights and lengths of the three liquid level tubes 2 are different, they can correspond to different water level heights respectively, thereby realizing graded detection of the flood level. When the water level inside the water level detection cylinder 1 rises, it will drive the float 401 inside the liquid storage tank 3 to rise. The float 401 rises steadily inside the liquid storage tank 3 through the cooperation of the slide rod 403 and the guide cylinder 402. The touch head 404 on the top of the float 401 touches the touch switch 405 on the top of the liquid storage tank 3 as the float 401 rises. Once the touch switch 405 is triggered, it will form an electrical connection with the sound and light alarm 406, thereby starting the alarm. Alarm function: when the touch switch 405 is touched by the float 401, the sound and light alarm 406 will immediately emit sound and light signals to warn relevant personnel that the flood level has reached the preset dangerous level. This intuitive alarm method can quickly attract people's attention and take necessary countermeasures. At the same time, the protective tube 14 arranged inside the liquid storage tank 3 and the magnetic attraction of the magnetic block 15 and the magnetic block 2 16 on the top of the float 401 and the inner wall of the liquid storage tank 3 can effectively prevent the float 401 from flipping back and forth in the liquid level tube 2, ensuring the accuracy of the detection data and the reliability of the alarm signal. The installation component 6 uses multiple installation feet 701 and spiral ground plugs 703 to fix the device to the ground to prevent displacement or tipping due to flood impact. The reinforcement strip 17 further enhances the connection strength between the installation feet and improves the stability of the entire device.

[0037] Specifically, such as Figure 3 As shown, the liquid inlet stabilizing assembly 5 includes a liquid inlet filter 601 and a spiral leaf 602 . The liquid inlet filter 601 is installed at the bottom of the water level detection cylinder 1 , and the spiral leaf 602 is fixedly connected to the inner wall of the water level detection cylinder 1 .

[0038] Specifically, such as Figure 3As shown, a hollow tube 8 is provided in the middle of the spiral blade 602, and a rotating shaft 9 is rotatably connected to the middle of the hollow tube 8. A driving fan blade 10 is installed on the top of the rotating shaft 9, and a scraper 11 is installed on the bottom of the rotating shaft 9. The scraper 11 is in contact with the liquid inlet filter 601.

[0039] Specifically, such as Figure 3 As shown, a top cover 12 is installed on the top of the water level detection cylinder 1 , a plurality of ventilation grooves 13 are opened on the side wall of the top cover 12 , and the top cover 12 is movably connected to the rotating shaft 9 .

[0040] When a flood comes and enters the interior of the water level detection cylinder 1, the liquid inlet filter 601 filters the flood entering the water level detection cylinder 1, effectively blocking impurities and particulate matter in the water, preventing them from entering the water level detection cylinder 1 and affecting the normal operation of the liquid level tube 2. The fixed spiral blades 602 can stably decelerate the water flow entering the water level detection cylinder 1, so that the liquid level inside the water level detection cylinder 1 rises steadily, avoiding the rapid rise of the liquid level inside the water level detection cylinder 1 above the external liquid level due to excessive water flow speed. The flow of the flood will drive the air flow on the water surface, and the flow of the air flow causes the driving fan blades 10 to drive the rotating shaft 9 to rotate, and the scraper 11 contacts the liquid inlet filter 601, continuously removing impurities on the filter screen, maintaining the patency of the filter screen and the accuracy of filtration. The setting of the top cover 12 prevents external impurities from entering through the top of the water level detection cylinder 1.

[0041] By adopting the above technical solution, the problems that the existing water level detection and alarm device cannot detect and automatically alarm floods of different water levels and cannot facilitate observers to quickly observe the water level are solved.

[0042] Working principle: When the present application is in use, first, when the flood level rises, water will enter the water level detection cylinder 1 through these liquid level tubes 2. Since the top of the water level detection cylinder 1 is open, the flood entering the water level detection cylinder 1 is at the same liquid level as the external flood. Since the heights and lengths of the three liquid level tubes 2 are different, they can correspond to different water levels respectively, thereby realizing graded detection of the flood level. When the flood comes and enters the interior of the water level detection cylinder 1, the liquid inlet filter 601 filters the flood entering the water level detection cylinder 1, and the spiral blades 602 can The water flow entering the water level detection cylinder 1 is steadily decelerated, so that the liquid level inside the water level detection cylinder 1 rises steadily. When the water level inside the water level detection cylinder 1 rises, it will drive the float 401 inside the liquid storage tank 3 to rise. The float 401 rises steadily inside the liquid storage tank 3 through the cooperation of the slide rod 403 and the guide cylinder 402. The touch head 404 on the top of the float 401 touches the touch switch 405 on the top of the liquid storage tank 3 as the float 401 rises. Once the touch switch 405 is triggered, it will form an electrical connection with the sound and light alarm 406, thereby starting the alarm function.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
