[0132] Working principle:

[0133] In use, the guide column 201 is placed on both sides of the waterway, and the floating bed platform 102 is used to plant ecological restoration plants, which is normally submerged to a specified height below the water surface to purify the water body.

[0134] When navigation is needed, open the electromagnetic brake 304 and start the four lifting motors 302, the lifting motors 302 drive the lifting winch roller 303 to rotate through the output shaft, the lifting winch roller 303 rotates to wind and unwind the lifting traction cable 306, so that one end of the lifting end block 307 is wound and one end of the counterweight end block 308 is unwound, when one end of the lifting end block 307 is wound, it will pull the lifting assembly frame 309 on its surface to rise along the lifting guide bin 207, the lifting assembly frame 309 drives the side connection frame 109 through the connecting cylinder 313, so that the lifting frame 101, the floating bed platform 102 and the guide water screen 105 rise synchronously, and the plants are lifted to a specified height above the water surface, until the lifting motors 302 are turned off and the electromagnetic brake 304 is locked to fix the height of the floating bed platform 102.

[0135] When the guide water screen 105 rises, it will guide the water on its surface to both ends, and the water droplets below will flow to both ends along the road groove 106, and the water droplets above will be blocked by the guide water screen 105 and discharged along the two sides, thereby avoiding the pollution of the water droplets falling directly on the waterway below;

[0136] When the lifting end block 307 is lifted, if the lifting is normal, it will rise at a constant speed, and the safety traction cable 405 will move synchronously, when the lifting traction cable 306 is disconnected or the lifting end block 307 accelerates downward too fast, the safety traction cable 405 will trigger the speed limiter 402 to lock, so that the top of the safety traction cable 405 is fixed, at this time the slide cylinder 408 keeps descending, the fixed top of the safety traction cable 405 will form a drag to pull the conversion slider 407 up, when the conversion slider 407 slides up, it will pull the safety gear 411 outward through the transmission connecting rod 410, so that the safety gear 411 engages with the safety rack 205, and the descent of the lifting end block 307 stops.

[0137] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
