[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0024] An embodiment of the present utility model discloses a water conservancy flood prevention warning device.

[0025] Referring to Figures 1-4 , a water conservancy flood prevention warning device includes a base 1 and a vertical rod 2. Two vertical rods 2 are fixedly arranged on both sides of the upper surface of the base 1. The upper ends of the two vertical rods 2 are fixedly provided with a fixed shell 3. Both ends of the upper side of the fixed shell 3 are provided with grooves. A rotating rod 19 is rotatably arranged inside the grooves. A baffle 13 is fixedly sleeved on the rod wall of the rotating rod 19. A sealing gasket is arranged on one side of the baffle 13 close to the fixed shell 3 to improve the sealing performance between the baffle 13 and the fixed shell 3. Two connecting rods 4 are rotatably arranged in the middle of the fixed shell 3. Two alarms 5 are arranged on the lower side inside the fixed shell 3. One side of each of the two alarms 5 is fixedly sleeved with the corresponding connecting rod 4. The lower ends of the sides of the two alarms 5 close to each other are fixedly provided with a press switch 6. A floating plate 7 is arranged on the lower side of the fixed shell 3. Both ends of the floating plate 7 are movably sleeved with the corresponding vertical rods 2. Both sides of the upper surface of the floating plate 7 are fixedly provided with fixed rods 8. The upper ends of the fixed rods 8 are fixedly provided with a pressing block 9. A push rod 10 is fixedly arranged in the middle of the upper surface of the floating plate 7. The upper end of the push rod 10 extends to the inside of the fixed shell 3.

[0026] Referring to Figures 1-4, a transmission mechanism for driving the rotation of two connecting rods 4 is provided at the upper end of the push rod 10. The transmission mechanism includes a gear 17 and a rack 18. A push plate 11 is fixedly provided at the upper end of the push rod 10. L-shaped rods 12 are fixedly provided on both sides of the upper surface of the push plate 11. Racks 18 are fixedly provided at the upper ends of the two L-shaped rods 12. Gears 17 are fixedly sleeved on the front ends of the two connecting rods 4. The two racks 18 are respectively meshed with the corresponding gears 17. The cross-section of the push rod 10 is square, so that the push rod 10 cannot rotate, that is, it can slide stably.

[0027] Referring to Figures 1-4 , magnets 14 are fixedly embedded on the opposite sides of the two alarms 5. An installation rod 15 is fixedly provided inside the fixed shell 3 and above the corresponding alarm 5. An iron block 16 is fixedly provided on the lower side of the installation rod 15, which is convenient for limiting the unfolded alarm 5.

[0028] Referring to Figures 1-4 , a torsion spring 20 is movably sleeved on the rod wall of the rotating rod 19. The two ends of the torsion spring 20 are fixedly connected to the inner wall of the corresponding rotating rod 19 and the groove respectively. In the natural state, the elastic force of the torsion spring 20 will cause the rotating rod to drive the baffle 13 to rotate to the horizontal.

[0029] In the present utility model, in use, in the normal state, the alarm 5 is stored in the fixed shell 3 for protection, that is, the alarm 5 can be protected from sun and rain, the aging speed of the alarm 5 can be slowed down, and the service life of the alarm 5 can be improved. When the water level rises, it will drive the floating plate 7 to move upward, and then cause the push rod 10 to push the push plate 11. The push plate 11 drives the two L-shaped rods 12 to move upward, and then drives the two racks 18 to move upward. The rack 18 drives the corresponding gear 17 to rotate, that is, the connecting rod 4 drives the alarm 5 to rotate to the horizontal. At this time, the iron block 16 and the magnet 14 are magnetically adsorbed to keep the alarm 5 stable. The floating plate 7 continues to move upward until the pressing block 9 presses the push switch 6 to turn on the power supply of the alarm 5, so that the alarm 5 emits an alarm, that is, the function of flood prevention warning can be realized.

[0030] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
