[0031] like Figure 1 and Figure 2 and Figure 3 The bottom plate 4 extends to above the water surface of the irrigation area. An axial column 6 is fixed on the upper surface of the bottom plate 4. A lower platform 7 is fixed on the top of the column 6. A distance sensor 8 is fixed on the column 6. The top of the distance sensor 8 is flush with the upper surface of the lower platform 7. A movable column 9 is provided above the column 6. An upper platform 10 adapted to the lower platform 7 is fixed to the bottom of the movable column 9. A reflective plate 11 coordinated with the distance sensor 8 is fixed on the movable column 9. The bottom of the reflective plate 11 is flush with the bottom of the upper platform 10. A control component is provided on the bottom plate 4 to drive the movable column 9 to move in coordination with the water level of the irrigation area to determine the height of the water level change. A trigger component is provided on the bottom plate 4 to cooperate with the control component to contact the water surface of the irrigation area.
[0032] like Figure 1 and Figure 2 and Figure 3Through the cooperation of the trigger component and the control component, when the water level in the irrigation area rises, the movable column 9 will be driven to move upward, and the upward movement of the movable column 9 will drive the upper platform 10 fixed to the movable column 9 to move. Through the cooperation of the ranging sensor 8 and the reflector 11, the staff can clearly determine the rising range of the water level in the irrigation area based on the measured distance between the upper platform 10 and the lower platform 7, so as to warn the staff.
[0033] like Figure 1 and Figure 2 and Figure 3 The control assembly includes an ear seat 12 fixed on the base plate 4, and a rocker arm 13 is hingedly connected to the ear seat 12. An active rod 14 located above the base plate 4 is provided between the rocker arm 13 and the column 6. Two first links 15, a second link 16, a third link 17 and a fourth link 18 are hingedly connected to the active rod 14 from top to bottom. The two first links 15, the second link 16, the third link 17 and the fourth link 18 are arranged opposite to each other. One end of the first link 15 is hingedly connected to the top of the rocker arm 13, and the other end is hingedly connected to the upper side of the movable column 9.

[0034] like Figure 1 and Figure 2 and Figure 3 The trigger assembly includes a square groove 19 opened on the bottom plate 4 and located directly below the active rod 14. A square block 20 is slidably connected in the square groove 19. A float 21 is fixed to the bottom of the square block 20, which contacts the water surface of the irrigation area. The inner cavity of the square block 20 is hollow to reduce the weight of the square block 20 so that the square block 20 can float up as the water level rises.
[0035] like Figure 1 and Figure 2 and Figure 3 When the water level in the irrigation area is lower than the set minimum water level, the upper platform 10 and the lower platform 7 collide, and the distance sensor 8 measures the data as zero. When the water level in the irrigation area increases, the float 21 moves upward under the action of buoyancy, driving the square block 20 integrated with the float 21 to move upward. The square groove 19 guides the movement of the square block 20. When the square block 20 moves to collide with the bottom end of the active rod 14 and pushes the active rod 14 upward, through the cooperation of the first connecting rod 15, the second connecting rod 16, the third connecting rod 17 and the fourth connecting rod 18, the rocker arm 13 rotates around the hinged connection with the ear seat 12, and the movable column 9 moves upward, driving the upper platform 10 and the reflector 11 fixed to the movable column 9 to move upward. When the water level in the irrigation area is higher than the set maximum water level, the upper platform 10 moves to the highest point, and the distance sensor 8 measures the data as the set maximum water level.
[0036] like Figure 1 and Figure 2 and Figure 3 In order to guide the movement of the square block 20 in the vertical direction, a guide component is provided on the bottom plate 4.
[0037] like Figure 1 and Figure 2 and Figure 3 and Figure 5 The guide assembly includes a square guide plate 22 fixed to the inner wall of the square groove 19. The inner cavity of the square guide plate 22 is hollow, and the upper and lower ends are open. The square block 20 extends into the square guide plate 22 and is slidably connected to the square guide plate 22. The square guide plate 22 guides the movement of the square block 20.
[0038] like Figure 1 and Figure 2 and Figure 3 and Figure 5 In order to reduce the possibility that the square block 20 may fall off the square guide plate 22 and affect the use of the device, an anti-falling component that cooperates with the square block 20 is provided on the square guide plate 22.
[0039] like Figure 1 and Figure 2 and Figure 3 and Figure 5 The anti-slip assembly includes two guide grooves 23 provided on the square guide plate 22. The two guide grooves 23 are arranged opposite to each other. Short shafts slidingly connected to the guide grooves 23 are fixed on both sides of the square block 20. The short shaft passes through the square guide plate 22 through the guide groove 23. A dead stop 24 is fixed to the end of the short shaft passing through the square guide plate 22. A through hole 25 for the dead stop 24 and the short shaft to pass through and connected to the square groove 19 is provided on the bottom plate 4. The height of the guide groove 23 is equal to the difference between the lowest water level setting height of the irrigation area and the highest water level setting height of the irrigation area. By arranging the anti-slip assembly and the guide assembly, the influence of wind and waves on the float 21 can be reduced, and the stability of the device can be improved.
[0040] During use, the staff fixes the base 1 to the concrete or foundation of the irrigation area bank with screws 2, and the bottom plate 4 extends above the water surface of the irrigation area. When the water level of the irrigation area is higher than the set minimum water level, the float 21 contacts the water surface of the irrigation area. When the water level of the irrigation area is lower than the set minimum water level, the square block 20 does not push the active rod 14, the upper platform 10 and the lower platform 7 conflict, and the distance sensor 8 measures the data as zero. When the water level of the irrigation area increases and is lower than the set maximum temperature, the float 21 moves upward under the action of buoyancy. The upward movement of the float 21 will drive the square block 20 fixed with the float 21 to move upward in the square guide plate 22. The square guide plate 22, the short shaft, the dead stop 24 and the guide groove 23 cooperate to guide the movement of the square block 20. At the same time, the impact of wind and waves on the buoy 21 is reduced. The upward movement of the square block 20 will push the active rod 14 adapted to the square block 20 to move upward. Through the cooperation of the first connecting rod 15, the second connecting rod 16, the third connecting rod 17 and the fourth connecting rod 18, the rocker arm 13 rotates around the hinged connection with the ear seat 12, and the movable column 9 moves upward, driving the upper platform 10 and the reflector 11 fixed to the movable column 9 to move upward. At this time, the distance between the upper platform 10 and the lower platform 7 is measured through the cooperation of the ranging sensor 8 and the reflector 11, and then the rising range of the water level in the irrigation area is clarified. When the water level in the irrigation area is higher than the set height, the upper platform 10 moves to the highest point, and the data measured by the ranging sensor 8 is the set highest water level. At this time, the staff needs to deal with the irrigation area.
