After the range plate 103c loses contact with the rotary switch 103e, it is pushed by the deformation of the spring limit block 103f to rotate upward by a certain angle to ensure that the range plate 103c can contact the rotary switch 103e to turn off the light-emitting block 103d when descending, thereby saving electricity.

[0046] Preferably, when the lifting and pushing frame 101c drives the rotating push shaft 101f to move upward, the rotating disk 101l-1 pushes the lifting and pushing groove 101j from the inner side of the first rotating groove 101i to move upward under the limit of the limit block 101l-2 and the power connection block 101l-3. When the rotating disk 101l-1 moves into the second rotating groove 101k, the lifting and pushing frame 101c continues to rise vertically to a height of X. When the top of the lifting and pushing frame 101c reaches the bottom of the rotating disk 101l-1, the rotating push shaft 101f passes through the limit rotation groove 101g on one side and moves upward on the limit shaft 101 01e is limited and rotated 180 degrees, the energized connecting block 101l-3 is rotated to contact the energized sheet 101l-5, the alarm 101l-4 is energized and emits an alarm sound to warn, the limit block 101l-2 can ensure that when the rotating push shaft 101f moves upward, the rotating push shaft 101f is limited by pushing the lifting slot 101j to avoid deviation from the direction of movement, when the rotating disk 101l-1 rotates 180 degrees, the limit block 101l-2 is in the second rotating slot 101k to prevent the rotating disk 101l-1 from deflecting and maintain the limit.

[0047] Furthermore, one end of the limiting shaft 101e is set as a circular surface, the rotating pushing shaft 101f is adapted to the lifting pushing frame 101c, the lifting rod 102c is adapted to the lifting hole 102b, and the lifting pushing frame 101c is adapted to the fixed sleeve 101h.

[0048] Furthermore, the lifting and lowering slot 101j is respectively adapted to the power connection block 101l-3 and the limit block 101l-2, the limit rotation slot 101g is adapted to the limit shaft 101e, the two sets of spring limit blocks 103f are fixedly connected to one side of the lifting and lowering scale plate 103a, and the arc-shaped toggle block 103g is fixedly connected to one side of the limit frame 102d.

[0049] Furthermore, the rotary switch 103e is electrically connected to the light-emitting block 103d, a plurality of groups of scale grooves 103b are distributed in equidistant straight lines on one side of the lifting scale plate 103a, one end of the driving rod 202h is rotatably connected to the top of the moving vertical rod 202b, the rotating groove 202e is adapted to the gear 202g, and one side of the lifting sleeve rod 201f is fixedly connected to the fixed sleeve 101h.

[0050] It should be noted that the distance between the bottom of the lifting and pushing frame 101c and the rotating push shaft 101f is X, the distance between the top of the lifting and pushing frame 101c and the rotating disk 101l-1 is Y, and the distances X and Y are the same. After the rotating disk 101l-1 reaches the second rotating groove 101k, the rotating push shaft 101f continues to vertically rise to a height of X in the limited rotating groove 101g through the limiting shaft 101e, and the lifting and pushing frame 101c moves a distance of X. The top of the lifting and pushing frame 101c reaches the bottom of the rotating disk 101l-1, and the rotating disk 101l-1 rotates forward 180 degrees. After the rotating disk 101l-1 reaches the first rotating groove 101i, the rotating push shaft 101f continues to vertically descend to a height of Y in the limited rotating groove 101g through the limiting shaft 101e. 01c moves a distance Y, the distance between the top of the lifting push frame 101c and the bottom of the rotating disk 101l-1 is Y, the rotating disk 101l-1 reverses 180 degrees, one end of the spring limit block 103f is fixedly connected to one side of the lifting scale plate 103a through a spring, and the other end is fixedly connected to a squeezing block to limit the rotation range of the rotary switch 103e. When the rotary switch 103e loses contact with the arc-shaped toggle block 103g, the squeezing block pushes the rotary switch 103e to rotate a certain angle under the action of the spring, but will not contact the closing and opening of the rotary switch 103e, so that the rotary switch 103e always maintains the angle of contact with the arc-shaped toggle block 103g, and can contact the arc-shaped toggle block 103g again to open or close during the next lifting.

[0051] When in use, the present invention has a total of four use processes. The first use process is to adjust the warning height. By starting the motor 201d, the threaded rod 201e at the bottom is driven to rotate forward. The lifting sleeve rod 201f is fixedly connected to the limit sleeve rod 201g on one side and is limited by the smooth rod 201b, and remains fixed. The lifting sleeve rod 201f moves upward through the action of the thread, driving the fixed sleeve 101h fixedly connected on one side to move upward, thereby adjusting the height of the appropriate warning water level, which is convenient for adapting to a variety of working environments and working terrains.

[0052] In the second use process, observe the water level rise height. When the water level rises, the buoyancy pushes the suspension ball 101a to move upward, and the buoyancy lifting rod 101b moves upward with the suspension ball 101a. When the limit shaft 101e is in the limit rotation groove 101g and rises, it pulls the rotating push shaft 101f to move upward in the fixed sleeve 101h. The lifting rod 102c fixedly connected to the top of the rotating disk 101l-1 passes through the lifting hole 102b and contacts the lifting scale plate 103a, lifting the lifting scale plate 103a to move upward, and the several groups of range plates 103c in the lifting scale plate 103a move upward. When moving upward, the rotary switch 103e on one side contacts the arc-shaped toggle block 103g, pushing the rotary switch 103e to rotate downward, squeezing the spring limit block 103f to turn on the light-emitting block 103d to emit light, which is convenient for observing several groups of light-emitting blocks 103d emitting light in bad weather to know the height of the rising water level. After the range plate 103c loses contact with the rotary switch 103e, it is pushed by the deformation of the spring limit block 103f to rotate upward by a certain angle to ensure that the range plate 103c can contact the rotary switch 103e to turn off the light-emitting block 103d when descending, saving electricity.

[0053] The third use process is to reach the warning position to sound the alarm. The lifting scale plate 103a rises, driving the fixed cross bar 202a to rise. When the several groups of teeth 202c on one side of the movable vertical rod 202b fixedly connected to one side of the fixed cross bar 202a rise, they come into contact with the gear 202g, pushing the gear 202g to rotate 180 degrees around the rotating shaft 202f in the rotating groove 202e at the top of the support rod 202d, driving the fixed warning sign 202i to rotate 180 degrees to the top under the rotation of the driving rod 202h, and stand on the top of the device, so that the staff can observe the early warning in time.

[0054] In the fourth usage process, after reaching the flood-prone location, a quick alarm is triggered. When the lifting push frame 101c drives the rotating push shaft 101f to move upward, the rotating disk 101l-1 moves upward along the pushing and lifting groove 101j in the first rotating groove 101i under the limitation of the limiting block 101l-2 and the power-on connection block 101l-3. When the rotating disk 101l-1 moves into the second rotating groove 101k, the lifting push frame 101c continues to vertically rise by a height of X. When the top of the lifting push frame 101c reaches the bottom of the rotating disk 101l-1, the rotating push shaft 101f rotates 180 degrees under the limitation of the limiting shaft 101e through the limiting rotation groove 101g on one side. The power-on connection block 101l-3 rotates to contact the power-on piece 101l-5, and the alarm 101l-4 is powered on to emit an alarm sound for warning. The limiting block 101l-2 can ensure that when the rotating push shaft 101f moves upward, the rotating push shaft 101f is limited by pushing the lifting groove 101j to prevent the movement from deviating from the direction. When the rotating disk 101l-1 rotates 180 degrees, the limiting block 101l-2 is in the second rotating groove 101k to prevent the rotating disk 101l-1 from deflecting and maintain the limitation.

[0055] In summary, by setting the buoyancy lifting unit and the fixing unit, when the water level rises, the buoyancy pushing component moves upward and pushes the moving jacking component upward, so that the water level monitoring component rises according to the rising height of the water, and it is convenient for the staff to observe the number of luminous scales of the water level monitoring component to know the rising height of the water level. When the water level rises to the warning position, the warning component rotates to the top to warn the staff. When not dealt with in time, when the water level continues to rise to the flood-prone location, the moving jacking component stops moving, and the buoyancy pushing component continues to rise, pulling the alarm part to rotate and connect to power, and making a sound alarm, which is convenient for preventing floods and timely guarding against the rising of the water level.
