The floating ball 1 floats on the liquid level, when the liquid level is kept still, the driving force of the spring device 8 driving the rotating shaft 9 to rotate is counteracted with the gravity and the buoyancy of the floating block, the water distribution pipe 6 and other parts, and the height positions of the water distribution pipe 6 and the floating ball 1 are kept unchanged. When the liquid level descends, the floating block also descends, and when the floating ball 1 descends, the first reel 4 is driven by the first pull rope 2 to overcome the driving force of the spring device 8 under the action of gravity, the first reel 4 and the second reel 5 are driven to synchronously rotate in the forward direction, so that the second reel 5 is driven to rotate in the forward direction to release the second pull rope 3, the water distribution pipe 6 is put down, and the height of the water distribution pipe 6 is reduced. The circumference around the first reel 4 is equal to n times the circumference around the second reel 5, the distributor 6 is located at a distance from the bottom of the liquid level equal to n times the height of the liquid level, and when the float 1 is lowered to a height H, the distributor 6 is lowered to a height H equal to n times the height of the liquid level, so that the height of the distributor 6 is always maintained at a distance from the bottom of the liquid level equal to n times the height of the liquid level. For example, the initial position of the water distributor 6 is in the middle of the liquid level, and the water distributor 6 is always in the middle of the liquid level no matter where the liquid level descends. Similarly, when the height of the liquid level rises, the floating ball 1 rises under the action of buoyancy, the spring device 8 drives the rotating shaft 9 to rotate, so that the first winding wheel 4 and the second winding wheel 5 are driven to rotate reversely, the first pull rope 2 and the second pull rope 3 are wound, when the rising height of the floating ball 1 is H, the rising height of the water distribution pipe 6 is H which is one n times, and the height of the water distribution pipe 6 is always kept at a position which is equal to one n times of the height of the liquid level from the bottom of the liquid level. The rotating shaft 9, the first reel 4, the second reel 5 and the spring device 8 are all arranged above the liquid level without contacting with the liquid, while the second rope 3 is released during the liquid level falling from the highest level to the lowest level, so that the damp second rope 3 is not brought onto the second reel 5, whereas during the liquid level falling from the lowest level to the highest level, although the second cord 3 is wound, the length of the second cord 3 immersed in the liquid increases, therefore, the wet second pull rope 3 is not brought to the second reel 5, the problem that the pull rope drives the liquid to flow into the rotating shaft 9 after driving the reel is avoided, therefore, the failure that the rotation cannot be realized due to corrosion cannot occur, the two pull ropes in contact with the liquid only need to be wound on the reel, the pull ropes do not need to rotate and the like, and the problem that the height adjustment fails due to corrosion of the parts soaked underwater for a long time can be well solved.

Specifically, the number of the second reels 5 is several, and the second reels 5 are connected to different water distribution pipes 6 through second pull ropes 3, respectively. A plurality of second reels 5 are arranged on the rotating shaft 9, each second reel 5 is connected with one water distribution pipe 6 through a second pull rope 3, so that the heights of the water distribution pipes 6 can be adjusted simultaneously, and the water distribution pipes 6 can be arranged at different height positions in liquid according to different medicaments needing to be added. The relative height of the water distribution pipes 6 on the liquid level can be accurately controlled, and the problem of height adjustment failure caused by corrosion of the parts soaked under water for a long time is well solved.
Specifically, first reel 4 and second reel 5 are fixed respectively on sleeve 11, sleeve 11 inner wall is equipped with spout 12, pivot 9 be equipped with spout 12 complex slide rail 13, sleeve 11 outer wall is equipped with first helicla flute 14, mount pad 10 is equipped with and inserts first helicla flute 14's arch 15. The sleeve 11 is capable of moving in the axial direction relative to the rotary shaft 9 but is not capable of rotating relative to the rotary shaft 9. The mounting seat 10 is provided with a projection 15 inserted into the first spiral groove 14, and the sleeve 11 is pushed by the projection 15 when rotated, so that the sleeve 11 moves in the axial direction of the rotating shaft 9, and the sleeve 11 can drive the first reel 4 and the second reel 5 to move in the axial direction. The stay ropes can be uniformly distributed on the winding wheel when being wound, the stay ropes are not overlapped on the winding wheel, the inner diameters of the stay ropes when being wound are kept the same, and the control precision of the height of the water distribution pipe 6 is improved.
Specifically, a protecting sleeve 16 is arranged at the lower end of the second pull rope 3. The outer surface of second stay cord 3 is wrapped to the protection casing, avoids liquid submergence to second stay cord 3, protects second stay cord 3 to avoid being corroded.

The diameter of the collar 21 is larger than that of the vertical pipe, and the collar 21 slides up and down along the vertical rod 22, so that the water distribution pipes 6 move in the vertical direction.
Example 2
Referring to fig. 3, the present embodiment is different from embodiment 1 in that the spring device 8 includes a pressure spring 18 and a sliding block 19, the sliding block 19 is slidably connected to the mounting seat 10, one end of the pressure spring 18 is fixedly connected to the sliding block 19, the other end of the pressure spring 18 is fixedly connected to the mounting seat 10, the rotating shaft 9 is provided with a second spiral groove 20, the sliding block 19 is inserted into the second spiral groove 20, the pressure spring 18 pushes the sliding block 19 to move, so as to drive the rotating shaft 9 to rotate, and a lift angle of the second spiral groove 20 decreases in a direction approaching to the pressure spring 18. When the liquid level drops, the first pull rope 2 and the second pull rope 3 drive the rotating shaft 9 to rotate, and the sliding block 19 is inserted into the second spiral groove 20, so that the rotating shaft 9 pushes the sliding block 19 to move towards the pressure spring 18, and the pressure spring 18 is accumulated. During the process of accumulating the pressure spring 18, the deformation of the pressure spring 18 is increased, but because the lead angle of the second spiral groove 20 along the direction close to the pressure spring 18 is reduced, the rotating shaft 9 can more easily push the pressure spring 18 to accumulate the force, and the torque required by the rotating shaft 9 to drive the spring to accumulate force is kept unchanged through the change of the lead angle. When the liquid level rises, the pressure spring 18 releases elastic potential energy to push the sliding block 19 to move, and as the rising angle of the second spiral groove 20 along the direction close to the pressure spring 18 is reduced, the pressure spring 18 pushes the rotating shaft 9 to rotate laboriously in the initial state, the rotating shaft 9 is pushed to rotate gradually and easily along with the movement of the sliding block 19, and the deformation of the spring is reduced at the moment, and the effects of the two are mutually counteracted, so that the moment generated by the pressure spring 18 on the rotating shaft 9 is kept unchanged. Under the condition that the moment of the rotating shaft 9 is kept unchanged, the pulling forces of the first pulling rope 2 and the second pulling rope 3 on the floating block and the water distribution pipe 6 are kept unchanged, so that the relative position of the water distribution pipe 6 on the liquid level is convenient to adjust and control.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
