The first-level filter screen 102 can filter large debris such as leaves and can allow tiny floats to pass through. A plurality of collecting boxes 6 that can rotate along the axis of the annular cavity 101 are rotatably installed in the annular cavity 101. The top wall of the collecting box 6 is inclined from the middle of the collecting box 6 to both sides. A secondary filter screen 601 that can prevent floats from passing through is installed on the two inclined walls of the collecting box 6. A gap 602 is provided between the two secondary filter screens 601. A plurality of cleaning brushes 7 are circumferentially installed in the annular cavity 101 for sliding around the axis of the annular cavity 101. An elastic member 701 is connected between the cleaning brush 7 and the top wall of the annular cavity 101 so that the cleaning brush 7 can slide along the axial direction of the annular cavity 101. Among them, connecting rods 702 are fixedly installed at both ends of the cleaning brush 7, and a slide groove 703 corresponding to the connecting rod 702 is provided at the bottom end of the floating platform 1. The connecting rod 702 is slidably installed in the slide groove 703, and the elastic member 701 is fixedly connected between the top wall of the connecting rod 702 and the top wall of the slide groove 703. The elastic member 701 includes but is not limited to a spring.

[0025] In this solution, a power mechanism 11 is installed on the floating platform 1, and the power mechanism 11 is used to provide power for the floating platform 1 to move along the water surface, so that the floating platform 1 can cruise and move in the pre-repair area. After the floating platform 1 moves to the preset repair point, the winch 2 is started to drive the support plate 3 to move downward to move the membrane frame assembly 4 to a preset depth. There are four winches 2, and the four winches 2 are circumferentially arranged with the axis of the floating platform 1 as the center to ensure the stability of the lifting and lowering of the support plate 3; then, aeration is performed at the membrane frame assembly 4 in the water through the aeration mechanism 5 to increase the dissolved oxygen in the water and gather microorganisms to form a biofilm, degrade pollutants in the water, and inhibit the release of pollutants from the bottom mud; among them, the aeration operation of the aeration mechanism 5 is a conventional technical means in this field, and its structure and aeration are not described here. The principle is described in detail; when the aeration mechanism 5 brings the scum in the water to the water surface through aeration, it floats around the floating platform 1, and the floating platform 1 moves in a cruising manner, so that the float enters the annular cavity 101, wherein the first-level filter 102 can prevent large debris from entering, and then the collection box 6 is rotated, so that the scum entering the annular cavity 101 adheres to the inclined edge of the collection box 6. During the rotation of the collection box 6, the cleaning brush 7 always maintains contact with the top wall of the collection box 6 under the action of the elastic member 701, driving the cleaning brush 7 to move upward to scrape the scum attached to the inclined edge of the collection box 6 to the notch 602 and fall into the collection box 6, thereby achieving the purpose of collecting the scum to improve the water sensory experience and water quality; wherein, when the floating platform 1 floats on the water surface, the water surface is located at the inclined edge of the collection box 6.

[0026] In one embodiment of the present invention, a plurality of scrapers 603 are installed in the notch 602 , and the scrapers 603 extend above the notch 602 so that when the cleaning brush 7 passes through the notch 602 during the rotation of the collection box 6 , the scrapers 603 can scrape off the scum attached to the cleaning brush 7 .

[0027] In one embodiment of the present invention, the membrane frame assembly 4 includes a shell 401 and a membrane frame installed in the shell 401, and a plurality of fixing holes 301 are circumferentially arranged on the support plate 3 with the axis of the support plate 3 as the center. The shell 401 is threadedly connected to the fixing holes 301 by bolts to fix the shell 401 on the support plate 3. By setting a plurality of fixing holes 301, the installation position and installation quantity of the membrane frame assembly 4 can be adjusted; the shell 401 is provided with an opening along the radial direction of the support plate 3, and the membrane frame includes two scissor-type telescopic frames 402 symmetrically arranged about the central cross-section of the shell 401, and a rod frame 403 is rotatably connected between the corresponding end hinge points of the two scissor-type telescopic frames 402. Driving the scissor-type telescopic frames 402 to extend or compress can adjust the length of the membrane frame.

[0028] In one embodiment of the present invention, a plurality of membrane rack assemblies 4 are circumferentially mounted on the support plate 3 with the axis of the support plate 3 as the center, so as to increase the biofilm hanging range and improve the ecological restoration capability.

[0029] In one embodiment of the present invention, a telescopic tube 8 is installed in the shell 401, and the telescopic tube 8 includes a plurality of connecting tubes 801 that are slidably connected in sequence. Each connecting tube 801 is provided with a plurality of discharge holes 802, and a one-way valve (not shown in the figure) is provided in the discharge hole 802. The connecting tube 801 away from the shell 401 is closed and fixedly connected to a connecting frame 803 on the side away from the shell 401. A strip sliding hole 804 is provided in the connecting frame 803, and the rod frame 403 away from the shell 401 is slidably set in the strip sliding hole 804, so that the extension or compression of the scissor-type telescopic frame 402 can drive the extension or compression of the telescopic tube 8. The connecting tube 801 close to the shell 401 is provided with a feed port, and the feed port is connected to a storage box 9 installed on the floating platform 1 through a discharge pipe. The storage box 9 stores biological bacteria agent, and the biological bacteria agent in the storage box 9 is transferred to the telescopic tube 8 along the discharge pipe through the pump body 10.

[0030] In this solution, the scissor-type telescopic frame 402 is slid to extend to a preset length, and the scissor-type telescopic frame 402 simultaneously extends the telescopic tube 8. To administer the bioinfectant, the pump 10 is activated to transfer the bioinfectant from the storage tank 9 into the telescopic tube 8. A one-way valve in the discharge port 802 allows the liquid in the connecting tube 801 to flow unidirectionally into the water outside the connecting tube 801. When the telescopic tube 8 is filled with bioinfectant, pressure squeezes the one-way valve, opening the discharge port 802. At this point, the bioinfectant in the telescopic tube 8 is sprayed evenly and synchronously onto the biofilm. This ensures uniform spraying of the bioinfectant, and the telescopic tube 8 and the scissor-type telescopic frame 402 extend and retract synchronously, eliminating the need for separate drive to extend or compress the telescopic tube 8.

[0031] In one embodiment of the present invention, a groove 103 is provided on the bottom side of the floating platform 1, and the aperture of the groove 103 is consistent with the diameter of the support plate 3. The support plate 3 and the membrane frame assembly 4 can be retracted into the groove 103 to reduce the space occupied by the ecological restoration device when not in use; the support plate 3 is provided with a leakage hole 302 connected to the groove 103, so that after the support plate 3 returns to the groove 103, the water in the groove 103 can leak out from the leakage hole 302.

[0032] In one embodiment of the present invention, a transparent cover 12 is provided on the floating platform 1 to prevent water waves from entering the surface of the floating platform 1 during the movement of the floating platform 1 .
