[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1 and Figure 3 As shown, a water environment monitoring device with adaptive water level includes a floating platform 1. The interior of the floating platform 1 is hollow and the floating platform 1 is in a sealed state. A water quality detector 23 is arranged at the center of the lower surface of the floating platform 1 to monitor the water quality in real time. The bottom of the floating platform 1 is symmetrically provided with inclined legs 2. The bottom of the inclined legs 2 is inclined outward. When not in use, the device can be supported by the inclined legs 2. The inclination outward can better improve the stability. The inclined legs 2 are connected to the inside of the floating platform 1. A winding wheel 10 is symmetrically installed at the bottom of the floating platform 1 through a bearing. A fixing rope 11 is wound on the surface of the winding wheel 10. The fixing rope 11 passes through the inclined legs 2. The inclined legs 2 can make the four fixing ropes 11 tilt downward to improve the fixing effect of the floating platform 1. The bottom of the fixing rope 11 is connected with a sinker 12, and the fixing rope 11 is pulled by the contact between the sinker 12 and the riverbed sludge.

[0025] Please refer to Figure 3As shown, a ratchet 13 is coaxially arranged on one side of the winding wheel 10, and a spring 24 is connected to the other side of the winding wheel 10. When the pull rope 21 is pulled out, the winding wheel 10 is driven to rotate. At this time, the spring 24 stores force, and the gravity of the sinker 12 is greater than the buoyancy of the floating platform 1 to prevent the overall position of the equipment. The buoyancy of the floating platform 1 is greater than the elastic force of the spring 24 to ensure that the pull rope 21 can be pulled out by buoyancy when the water level rises. The installation direction of the spring 24 is to store force when the pull rope 21 is pulled out, and the ratchet 13 rotates together with the winding wheel 10. The inner wall of the floating platform 1 is vertical A slide groove 14 is provided, and the slide groove 14 corresponds to the position of the winding wheel 10. A track rod 15 is vertically arranged inside the slide groove 14, and a slider 16 is slidably installed under the surface of the track rod 15. The track rod 15 is used to ensure the stability of the movement of the slider 16. An extension rod 17 is laterally arranged on the side of the slider 16 close to the center of the winding wheel 10, and a limit head 18 is arranged below the end of the extension rod 17 away from the slider 16. The limit head 18 cooperates with the ratchet 13, and the cooperation direction of the two must ensure that the fixing rope 11 cannot be pulled down when cooperating with each other.

[0026] Among them, a spring 19 is sleeved on the surface of the track rod 15, and the bottom of the spring 19 is in contact with the upper surface of the slider 16. The spring 19 ensures that the slider 16 is placed at the bottom of the stroke when not subject to tension, so that the limit head 18 and the ratchet 13 cooperate with each other. The outer surface of the floating platform 1 is symmetrically installed with a guide wheel 20 through a pin shaft. The guide wheel 20 is placed obliquely above the slide groove 14. A pull rope 21 is connected to the surface of the slider 16. The pull rope 21 passes through the guide wheel 20. The end of the pull rope 21 away from the slider 16 is connected to a float 22. The float 22 is placed on the outside of the floating platform 1. When the water level rises, the height of the floating platform 1 cannot change, but the float 22 can move up, and then pull the slider 16 up, so that the ratchet 13 is disengaged, so that the fixed rope 11 can change.

[0027] Please refer to Figure 1 and Figure 2 As shown, a support frame 3 is vertically arranged on the upper surface of the floating platform 1, and four open grooves 7 are symmetrically opened on the surface of the support frame 3, and the four open grooves 7 are connected with the inside of the support frame 3. A threaded rod 5 is vertically installed inside the support frame 3 through a bearing, and a driving motor 4 is arranged above the inside of the floating platform 1. The output shaft end of the driving motor 4 is coaxially connected with the threaded rod 5, and the threaded rod 5 is concentric with the support frame 3. The threaded rod 5 can be controlled to rotate by the driving motor 4.

[0028] Among them, a solar panel 8 is symmetrically installed on the upper outer side of the support frame 3 through a pin shaft, and the position of the solar panel 8 corresponds to the open groove 7. A movable block 6 is screwed on the surface of the threaded rod 5, and four connecting rods 9 are symmetrically installed on the surface of the movable block 6 through a pin shaft. The connecting rod 9 passes through the open groove 7, and one end of the connecting rod 9 away from the movable block 6 is installed on the inner surface of the solar panel 8 through a pin shaft. The rotation of the threaded rod 5 can drive the movable block 6 to move up and down, and then adjust the angle of the solar panel 8 to adapt to different lighting environments.

[0029] When in use: place the floating platform 1 on the water surface, the interior of the floating platform 1 is hollow and has buoyancy. At the same time, due to the presence of the spring 19, the slider 16 is placed at the bottom of the stroke, and then the limit head 18 and the ratchet 13 cooperate with each other, so that the sinker 12 cannot move down. At this time, downward pressure can be applied to the floating platform 1, and the buoyancy makes the float 22 and the inclined support leg 2 move upward relative to each other, and then the slider 16 is pulled up by the pull rope 21, so that the limit head 18 is separated from the cooperation with the ratchet 13. At this time, the sinker 12 automatically pulls the fixing rope 11 downward, and the spring 24 at the other end is subjected to rotational storage force. The four sinkers 12 are placed at the four corners of the floating platform 1 by the guidance of the inclined support leg 2 until the sinkers 12 contact the silt at the bottom of the river channel and no longer move downward. At this time, the floating platform 1 is released, and the sinkers 12 at the four corners are used to ensure the stability of the floating platform 1. The threaded rod 5 is controlled to rotate by the motor, and then the height of the movable block 6 is controlled. The rod 9 controls the relative angle of the solar panel 8 to adapt to different lighting environments. When the water level in the river rises, the floating platform 1 cannot move up due to the pulling of the sinker 12 and the fixed rope 11. At this time, the rising water level will drive the floating ball 22 to rise relatively. The above principle is used to make the limit head 18 disengage from the cooperation with the ratchet 13, so that the winding wheel 10 is out of the restriction. At this time, the floating platform 1 can move up due to the buoyancy. After moving up to the right position, the floating ball 22 no longer pulls the slider 16, so that the internal mechanism is in a stable state again. The buoyancy of the floating platform 1 is greater than the elastic force of the spring 24. Therefore, when the water level rises, the floating platform 1 can move up to pull out the pull rope 21. On the contrary, when the water level drops, the height of the floating platform 1 drops and the pull rope 21 relaxes. At this time, the elastic force of the spring 24 can be used to pull the pull rope 21 to keep it in a taut state, and the matching direction of the ratchet 13 and the limit head 18 can ensure that the winding wheel 10 tightens the pull rope 21 and cannot rotate in the opposite direction.

[0030] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
