DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0028] Specific embodiment one, please refer to Figures 1-10 ​This invention relates to an ecological restoration system based on river sewage treatment, comprising a lifting and guiding mechanism 1 installed on the hull and a protective restoration mechanism 2 located inside the lifting and guiding mechanism 1; the protective restoration mechanism 2 includes a restoration component 3 and an opening and closing control component 4 and a protective cover 5 mounted thereon; the restoration component 3 includes a hollow disc-shaped restoration part and a medicine delivery box 301, the protective cover 5 is located outside the disc-shaped restoration part, the disc-shaped restoration part and the medicine delivery box 301 are connected by a one-way guide pipe 302, and a sealed passage communicating with its inner cavity is provided below the medicine delivery box 301. The channel 303 and the medicine delivery box 301 are equipped with a piston disc 304. The buoyancy component 305 installed inside the sealed channel 303 is connected to the piston disc 304. The top of the medicine delivery box 301 is connected to the medicine inlet pipe 306. The opening and closing control component 4 includes a guide pipe 401 installed in the medicine inlet pipe 306 and a bottom sealing plate 402 installed below the sealed channel 303. The guide pipe 401 and the bottom sealing plate 402 move up and down synchronously. When the bottom sealing plate 402 is close to the bottom of the sealed channel 303, the guide pipe 401 is blocked by the pipe wall of the medicine inlet pipe 306.

[0029] In this embodiment of the invention, such as Figure 7 and Figure 8 As shown, the repair component 3 also includes an annular support chamber 307. The annular support chamber 307 has curved surfaces on both sides, and an arc-shaped guide groove 308 is provided on one side of the curved surface of the annular support chamber 307. Lifting guide seats 309 are installed on the curved surfaces on both sides of the annular support chamber 307. Sealing doors 6 are installed on both sides of the annular support chamber 307. Sealing doors 6 are connected to the annular support chamber 307 with fasteners for easy disassembly and assembly. The drug delivery box 301 is located at the bottom of the annular support chamber 307, and the drug delivery pipe 306 passes through the top of the annular support chamber 307. The sealed channel 303 is fixed at the bottom of the annular support chamber 307. An air pipe connector 310 communicating with the drug delivery box 301 is installed on the top of the annular support chamber 307.

[0030] Furthermore, the disc-type repair unit consists of a hollow guide disc 311 and a vortex-shaped repair component 312. The vortex-shaped repair component 312 is concentrically arranged on the outside of the guide disc 311 and the two are connected. Several repair openings are arranged along the trajectory direction on the inner wall of the vortex-shaped repair component 312. Under the action of airflow, the repair agent inside the vortex-shaped repair component 312 is injected into the riverbed sediment along the various repair openings arranged in the vortex. This achieves the treatment of toxic and harmful substances in the riverbed sediment by the repair agent. The annular bearing chamber 307 is connected to the guide disc 311 by a fixing frame 313. The protective cover 5 is located on the outside of the vortex-shaped repair component 312 and connected to the fixing frame 313. Figure 4As shown, when the vortex-shaped repair component 312 enters the inner side of the riverbed sediment, the protective cover 5 is inserted into the riverbed sediment to cover and protect the repair area where the vortex-shaped repair component 312 is located. When injecting repair agent and aerating the riverbed sediment, the influence of external water flow can be effectively avoided. The repair agent can treat pollutants in the sediment, and aeration can oxygenate the riverbed sediment to improve the activity of microorganisms, thereby further improving the treatment effect on the riverbed sediment and water. The effective combination of repair agent treatment and aeration treatment greatly improves the treatment effect on the river. The one-way guide pipe 302 is connected between the guide plate 311 and the guide box 301. A one-way valve 314 is installed on the one-way guide pipe 302. By setting the one-way valve 314 on the one-way guide pipe 302, the river water can be effectively prevented from flowing back into the guide box 301 along the one-way guide pipe 302. A steel rope connector 315 is fixed on the top of the annular bearing chamber 307.

[0031] In this embodiment of the invention, such as Figure 9 and Figure 10 As shown, the opening and closing control assembly 4 also includes a motor base 403 installed inside the annular bearing chamber 307. A submersible motor 404 (which is a waterproof motor) is installed on one side of the motor base 403. The output end of the submersible motor 404 is connected to the opening and closing control panel 405. An eccentric groove 406 is opened on the surface of the opening and closing control panel 405. The outer diameter of the guide tube 401 is the same as the inner diameter of the drug inlet tube 306, and its top is an open structure (that is, the guide tube 401 is only open at the top and sealed at the bottom). The circumferential side of the guide tube 401 is provided with a drug inlet 407 close to the bottom. When the guide tube 401 moves down along the drug inlet tube 306 to a designated position so that the drug inlet 407 communicates with the inner cavity of the drug delivery box 301, a certain amount of repair agent can be input into the drug delivery box 301 through the guide tube 401.

[0032] Furthermore, the opening and closing control assembly 4 also includes a linkage rod 408 that slides through the annular bearing chamber 307. A lifting plate 409 is fixed above the annular bearing chamber 307 between the guide pipe 401 and the linkage rod 408. A force-bearing component 410 fixed to the linkage rod 408 is slidably disposed inside the eccentric channel 406. A U-shaped support frame 411 is fixed between the bottom sealing plate 402 and the linkage rod 408. Thus, when the opening and closing control panel 405 is rotated by the submersible motor 404, the force-bearing component 410 can be squeezed by the eccentric channel 406 to move up and down. 8. Under the action of the U-shaped support frame 411 and the lifting plate 409, the guide pipe 401 and the bottom sealing plate 402 move up and down synchronously. It should be noted that a support ring (not shown in the figure) is fixed inside the medicine guide box 301. The piston disc 304 is initially supported by the support ring. The bottom of the buoyancy component 305 is flush with the bottom of the sealed channel 303. The lifting plate 409 is attached to the top of the annular bearing chamber 307. At this time, the medicine inlet 407 on the guide pipe 401 is connected to the inner cavity of the medicine guide box 301. There is a certain gap between the bottom sealing plate 402 and the sealed channel 303.

[0033] After a certain amount of remedial agent is introduced into the dosing box 301 through the inlet 407 on the guide pipe 401, the opening and closing control disc 405 is rotated, causing the linkage rod 408 to drive the guide pipe 401 and the bottom sealing plate 402 to move upward synchronously until the bottom sealing plate 402 is tightly attached to the bottom of the sealed channel 303. At this time, the inlet 407 on the guide pipe 401 retracts into the inlet pipe 306 and is sealed through the inner wall of the inlet pipe 306, completely isolating the entire inner cavity of the dosing box 301 from the outside. Then, the entire protective remedial mechanism 2 is controlled to move downward until the vortex remedial component 312 enters the inner side of the riverbed sediment (it should be noted that after the remedial agent is replenished...). During the downward movement of the entire protective repair mechanism 2, after the sealing plug 109 seals the vertical output pipe 106, the remaining repair agent in the horizontal gravity flow pipe 107 and L-shaped gravity flow pipe 108 flows directly into the river water to achieve river water treatment. The protective cover 5 is inserted into the riverbed sediment to cover and protect the repair area where the vortex-shaped repair component 312 is located. Then, the opening and closing control panel 405 is rotated in the opposite direction by a certain angle, so that the linkage rod 408 drives the guide pipe 401 and the bottom sealing plate 402 to move downward synchronously to the designated position. At this time, the inlet 407 on the guide pipe 401 is still sealed through the inner wall of the inlet pipe 306, while the bottom sealing plate 402 has been released from the seal. At the bottom of channel 303, the buoyancy component 305 within the sealed channel 303, under the action of buoyancy, drives the piston disc 304 to move upward. The upward-moving piston disc 304 squeezes the repair agent in the drug delivery box 301, causing the repair agent to enter the one-way guide tube 302. (It should be noted that the buoyancy provided by the buoyancy component 305 is large enough to completely expel the repair agent in the drug delivery box 301. The selection of the buoyancy component 305 is existing technology and will not be described in detail.) Subsequently, airflow is delivered into the drug delivery box 301 through the air pipe connector 310. The airflow entering the drug delivery box 301 enters the one-way guide tube 302, and under the action of the airflow, the repair agent in the one-way guide tube 302... The repair agent is delivered to the guide plate 311 and the vortex repair component 312, and then injected into the riverbed sediment through various repair ports. At the same time, a certain amount of air can also be delivered to the riverbed sediment. In this way, the treatment of riverbed sediment and water body can be achieved. After the treatment of this area is completed, the entire protective repair mechanism 2 is controlled to move upward to complete the reset. After the protective repair mechanism 2 is moved to the next treatment area by the ship, the opening and closing control plate 405 is first controlled to rotate in the opposite direction so that the linkage rod 408 drives the guide pipe 401 and the bottom sealing plate 402 to move downward synchronously back to the initial position. Then, the treatment of sediment and water body in this area is achieved in the same way as above.

[0034] Specific embodiment two, based on specific embodiment one, such as Figure 5As shown, the lifting guide mechanism 1 includes a mounting frame 101 fixed to the hull. Two vertical guide rail frames 102 are symmetrically fixed at the bottom of the mounting frame 101. The protective repair mechanism 2 is located between the two vertical guide rail frames 102, and the lifting guide seat 309 is slidably connected to the vertical guide rail frames 102. This ensures that the entire protective repair mechanism 2 moves smoothly up and down along the vertical guide rail frames 102. The vertical guide rail frames 102 can also be replaced according to the depth of the river channel. The steel rope on the winch installed inside the mounting frame 101 passes through the steel rope guide 103 and is connected to the steel rope connector 315. The winch is a commonly used rope winding structure in the prior art, so it will not be described in detail here. The lifting and lowering movement of the entire protective repair mechanism 2 can be controlled by the winch and the steel rope. The air supply device 104 installed inside the mounting frame 101 is connected to the air pipe connector 310 through a spring tube (the spring tube is a spiral-shaped, telescopic air pipe, which is prior art and will not be described in detail here).

[0035] In this embodiment of the invention, such as Figure 3 and Figure 5As shown, a repair agent storage tank 105 is provided inside the mounting bracket 101. A vertical output pipe 106, penetrating the mounting bracket 101, is connected to the bottom of the repair agent storage tank 105. A horizontal gravity flow pipe 107 is connected to the bottom of the vertical output pipe 106. An L-shaped gravity flow pipe 108 is connected to one end of the horizontal gravity flow pipe 107. A sealing plug 109 is provided inside the horizontal gravity flow pipe 107. A moving rod 110, penetrating the corresponding vertical guide rail bracket 102, is fixed to the end of the sealing plug 109. Below the moving rod 110, a device penetrating the corresponding vertical guide rail bracket 102 is provided. The second movable rod 111 is connected to the first movable rod 110 via a connecting plate 112. The connecting plate 112 is connected to the corresponding vertical guide rail frame 102 via an elastic element 113. In the initial state, the vertical output pipe 106 is blocked by the sealing plug 109, and the repair agent in the repair agent storage tank 105 cannot flow from the vertical output pipe 106 to the horizontal gravity flow pipe 107. After the entire protective repair mechanism 2 is controlled to move upward and complete the reset, the sliding ball at the end of the second movable rod 111 just touches the arc-shaped guide groove 308. Internally, the protective repair mechanism 2 continues to move upward to the repair agent filling station. During this process, the moving rod 111 slides along the arc-shaped guide groove 308 and moves in a direction away from the L-shaped self-flowing pipe 108. Under the action of the connecting plate 112, the elastic element 113 is gradually stretched. The moving rod 110, which moves synchronously with the connecting plate 112, drives the sealing plug 109 to release the blockage on the vertical output pipe 106. Since the L-shaped self-flowing pipe 108 is inserted into the connecting pipe 401, a certain amount of repair agent in the repair agent storage tank 105 is released. The liquid flows along the vertical output pipe 106, horizontal gravity flow pipe 107, L-shaped gravity flow pipe 108 and guide pipe 401 into the medicine delivery box 301. After the set replenishment time of the repair agent is reached, the protective repair mechanism 2 is controlled to move downward to the initial position (that is, the ball at the end of the moving rod 111 just touches the inside of the arc-shaped guide groove 308). At this time, under the elastic restoring force of the elastic element 113, the sealing plug 109 completes the sealing of the vertical output pipe 106 again, and then the ecological restoration and treatment of the riverbed sediment and water body can begin.
