[0069] Specifically, the number of the limiting rods 302a is two.

[0070] The opposite sides of the two limiting rods 302a are connected to the limiting blocks 302b.

[0071] Specifically, the limiting rod 302a is located inside the limiting groove 302c. Through the arrangement of the limiting rod 302a and the limiting groove 302c, the liquid storage tube 303b is more stable when rising and falling.

[0072] Furthermore, the recursive part 303 includes a sleeve 303a arranged on the floating block 202b, a liquid storage tube 303b arranged on the second partition plate 301b, an extrusion tube 303c arranged on the liquid storage tube 303b, a first extrusion rod 303d arranged inside the extrusion tube 303c, and a push block 303e arranged on the first extrusion rod 303d.

[0074] Specifically, the limiting block 302b can prevent the liquid storage tube 303b from falling.

[0075] The limiting groove 302c is arranged on the outer wall of the liquid storage tube 303b.

[0076] The center position of the top of the floating block 202b is connected to the sleeve 303a.

[0080] The bottom end of the first extrusion tube 303c extends to the outside of the extrusion tube 303c and is connected to the push block 303e.

[0081] Specifically, when the sleeve 303a gradually rises, the floating block 202b will contact the push block 303e and drive the push block 303e to rise, and the push block 303e drives the first extrusion rod 303d to rise inside the sleeve 303a. When the push block 303e contacts the bottom of the extrusion tube 303c, the push block 303e drives the first extrusion rod 303d to rise while driving the extrusion tube 303c to rise together.

[0082] Furthermore, the squeezing portion 304 includes a spring 304a disposed on the first squeezing rod 303d, a second squeezing rod 304b disposed on the spring 304a, a squeezing block 304c disposed on the second squeezing rod 304b, and a storage groove 304d disposed on the liquid storage tube 303b.

[0083] One end of the first squeezing rod 303d away from the pushing block 303e is connected to the spring 304a.

[0084] One end of the spring 304a away from the first extrusion rod 303d is connected to the second extrusion rod 304b.

[0085] One end of the second squeezing rod 304b away from the spring 304a passes through the liquid storage tube 303b and is connected to the squeezing block 304c.

[0086] The storage tank 304d is arranged on the top of the liquid storage tube 303b.

[0087] Specifically, when the second squeezing rod 304b is not subjected to the upward thrust, the squeezing block 304c is located inside the storage groove 304d.

[0088] Furthermore, the warning part 305 includes an infusion groove 305a arranged on the second extrusion rod 304b, a piston 305b arranged on the extrusion tube 303c, a folding bag 305c arranged on the second partition plate 301b, a folding cylinder 305d arranged on the folding bag 305c, a liquid inlet 305e arranged on the third partition plate 301c, and a stopper 305f arranged on the folding cylinder 305d.

[0089] The infusion groove 305a is disposed on the side wall of the second extrusion rod 304b, and the infusion groove 305a is located at one end adjacent to the extrusion block 304c.

[0090] Specifically, when the second squeezing rod 304b rises, through the provision of the infusion groove 305a, the liquid inside the liquid storage tube 303b can be discharged through the infusion groove 305a when being squeezed.

[0091] The piston 305b is located inside the liquid storage tube 303b, and the piston 305b is installed on the top of the extrusion tube 303c.

[0092] Specifically, a green solution is disposed inside the liquid storage tube 303b, and the solution is located above the piston 305b.

[0094] The opening of the folded bag 305c faces upward, and the folded bag 305c is wrapped around the outside of the liquid inlet 305e.

[0095] Specifically, the bottom of the foldable bag 305c is a hard plate, and a red solution is disposed inside the foldable bag 305c.

[0096] Specifically, when the folding bag 305c shrinks, the red solution will enter the upper part of the third partition plate 301c through the liquid inlet 305e.

[0097] A folding tube 305d is disposed at the center of the folding bag 305c.

[0098] Specifically, the opening of the folding cylinder 305d faces downward, and the folding cylinder 305d is located directly above the pressing block 304c.

[0099] A stopper 305f is provided at the top of the folding cylinder 305d, and the top of the stopper 305f contacts the third partition plate 301c.

[0100] Specifically, when the folding tube 305d is pushed upward, the folding tube 305d may be folded, but the folding tube 305d cannot enter the interior of the liquid inlet 305e.

[0101] Operation process: As the water level gradually rises, for safety reasons, the staff cannot directly walk to the monitoring device for observation. In order to better observe the current water level, when the water level rises, the river water drives the floating block 202b, and the floating block 202b drives the casing 303a to rise. When the push block 303e contacts the top of the floating block 202b, the floating block 202b continues to rise and can drive the push block 303e to rise together. The push block 303e drives the first extrusion rod 303d to rise, and the first extrusion rod 303d drives the spring 304a to rise. The spring 304a drives the second extrusion rod 304b to rise, and the second extrusion rod 304b drives the extrusion block 304c from the inner part of the storage groove 304d. Part of it is detached, so that part of the infusion groove 305a is located above the second partition plate 301b. At this time, when the float block 202b rises, the float block 202b drives the push block 303e to contact the bottom of the squeezing tube 303c. At this time, when the float block 202b rises, the float block 202b can drive the squeezing tube 303c to rise together. During the rising process of the squeezing tube 303c, it can drive the piston 305b to squeeze the green liquid inside the storage tube 303b, so that the liquid of the green leaves enters the second partition plate 301b through the infusion groove 305a. When the staff can see the green solution through the second observation port 203b, they can judge the water level at this time.

[0102] When the river water continues to rise, the floating block 202b continues to rise, the piston 305b can contact the top surface inside the liquid storage tube 303b, and the top of the extrusion block 304c can contact the top of the folding tube 305d. At this time, when the floating block 202b continues to rise, the first extrusion rod 303d squeezes the spring 304a, causing the spring 304a to contract. At this time, the top of the sleeve 303a contacts the bottom of the liquid storage tube 303b. When the floating block 202b rises, the sleeve 303a drives the liquid storage tube 303b upward to rise. When the liquid storage tube 303b rises, the liquid storage tube 303b can drive the folding bag 305c to retract upward, and the folding bag 305c drives the folding tube 305d to fold together, so that the red liquid inside the folding bag 305c enters the top of the third partition plate 301c through the liquid inlet 305e. The staff can observe whether there is red liquid through the first observation port 203a to determine whether the current water level is in a dangerous state.
