[0027] An embodiment of the utility model provides a water level warning device for water conservancy projects.

[0028] Please refer to Figure 1 , which includes a monitoring water cylinder 1. A barrier filter screen 6 is fixedly connected to the end of the monitoring water cylinder 1. The barrier filter screen 6 can prevent sundries in the water from entering the monitoring water cylinder 1 along with the water, and avoid the sundries jamming the warning floating ball 5 and the monitoring water cylinder 1, thus affecting the monitoring and warning effect of the device.

[0029] A counterweight box 7 is fixedly connected to the outside of the monitoring water cylinder 1. The counterweight box 7 has a certain weight, which can increase the stability of the device in the water, keep the device in a vertical state, avoid the device from tilting due to the undulation of water waves, and reduce the influence of external factors on the monitoring and warning of the device.

[0030] The bottom surface of the counterweight box 7 is fixedly connected with an installation base 8, and a group of installation fixing pieces 9 are fixedly connected to the outer surface of the installation base 8. Through the setting of the counterweight box 7, it is convenient for the staff to fix the device at a specific warning position. The staff inserts bolts into the installation fixing pieces 9 and fixes them underwater, so that the device can be kept stable during the monitoring process, ensuring that the device can carry out warning operations stably.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , the top end of the monitoring water cylinder 1 is fixedly connected with a warning sleeve 2. Scale lines are left on the outer surface of the warning sleeve 2, which is convenient for the staff to adjust the position of the warning mechanism 4 through the scale lines, so that the device can adjust the water level warning height according to actual needs, increasing the warning accuracy of the device and improving the applicability of the device.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a warning mechanism 4 for warning the water level is arranged outside the warning sleeve 2; the warning mechanism 4 includes a warning slide rod 401 slidably connected to the warning sleeve 2 and a touch alarm 404. An audible and visual alarm is installed on the touch alarm 404. The touch alarm 404, the trigger rod 405 and the audible and visual alarm involved in this application are all prior arts, and will not be elaborated too much in this application.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4 , the bottom end of the warning slide rod 401 is fixedly connected with a transmission leather sleeve 402. The transmission leather sleeve 402 slides inside the monitoring water cylinder 1. The warning slide rod 401 and the transmission leather sleeve 402 are both made of lightweight materials to reduce their weight, and their surfaces are both anti-slip treated to reduce the friction between them and the monitoring water cylinder 1 and the warning sleeve 2, reducing the influence of external forces on the water level detection accuracy.

[0034] Please refer to Figure 2 , a warning float ball 5 is arranged inside the monitoring water cylinder 1. The transmission leather sleeve 402 is adapted to the warning float ball 5. The warning float ball 5 is made of plastic and is hollow inside. When water enters the monitoring water cylinder 1, the warning float ball 5 will float upward under the push of the water. When the warning float ball 5 floats upward, the transmission leather sleeve 402 can block the warning float ball 5, and the buoyancy generated by the upward floating of the warning float ball 5 will push the transmission leather sleeve 402 to slide upward.

[0035] Please refer to Figure 3, a warning top block 403 is fixedly connected to the top end of the warning slide bar 401. The warning top block 403 is slidably connected to the warning sleeve 2. When the transmission leather sleeve 402 slides upward, it can drive the warning top block 403 to slide upward inside the warning sleeve 2, so that the warning top block 403 touches the trigger rod 405. The diameter of the warning top block 403 is slightly larger than that of the warning slide bar 401. When the warning slide bar 401 slides inside the warning sleeve 2, the warning top block 403 can prevent the warning slide bar 401 from detaching from the warning sleeve 2 under the action of gravity, thus causing the device to lose its warning function.

[0036] Please refer to again Figure 1 , Figure 2 , Figure 3 and Figure 4 , a trigger rod 405 is fixedly installed in the middle of the touch - type alarm 404. The touch - type alarm 404 can accurately detect the touch of the warning top block 403 through the upward pressure and rebound of the trigger rod 405. When the warning top block 403 touches the trigger rod 405, the touch - type alarm 404 will emit a beeping alarm sound and send a warning message to the remote control terminal. This warning method has the advantages of high accuracy and long service life.

[0037] An adjustment chute 3 is provided inside the warning sleeve 2. The trigger rod 405 is slidably connected to the adjustment chute 3. The trigger rod 405 is an elastic tube with good flexibility and resilience. When the warning top block 403 touches the metal tube, the trigger rod 405 will bend and transmit different levels of warning signals to the touch - type alarm 404 according to the degree of bending. If the water level is large, the warning top block 403 will push the trigger rod 405 to bend more than ninety degrees, avoiding damage to the trigger rod 405 and the touch - type alarm 404 caused by the rapid rise of the water level and extending the service life of the device.

[0038] Fixed collar rings 406 are hinged at both ends of the touch - type alarm 404. The two fixed collar rings 406 are fixed by bolts. Through the setting of the fixed collar rings 406, when the staff fixes the two fixed collar rings 406 together with bolts, the fixed collar rings 406 can lock the warning sleeve 2 well, thus fixing the touch - type alarm 404 and the trigger rod 405 at a specific height of the warning sleeve 2, facilitating the adjustment of the water level warning height of the device.

[0039] Working principle: First, the staff fixes the device at a suitable position for early warning operations by installing the fixing piece 9. Then, according to the actual water level early warning requirements, select the installation height of the touch alarm 404. Next, fix the two fixing collar rings 406 together with bolts to complete the installation of the device. When water enters the monitoring water cylinder 1 through the barrier filter screen 6, the warning float ball 5 will float upward under the push of water, thus pushing the transmission leather sleeve 402 to rise. The transmission leather sleeve 402 pushes the warning slide rod 401 to slide upward inside the warning sleeve 2. When the water level rises to the warning height, the warning top block 403 will touch the trigger rod 405. At this time, the touch alarm 404 will emit a beeping alarm sound and send a warning message to the remote control terminal to remind the staff to pay attention to the water level.

[0040] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
