[0034] Step 1: build a pre-reservoir at the end of the water channel 1 entering the lake, and plant aquatic plants in the river channel 1 by means of a woven net (the woven net is formed by cross-weaving of resin materials). The aquatic plants are planted in the hollow holes of the woven net to achieve the anchoring effect of the aquatic plants, which can increase the impact resistance of the aquatic plants in the water, and a counterweight structure is fixed at the corners of the woven net;

[0035] Step 2: a flow limiting mechanism 3 and a cleaning mechanism 4 are arranged in the river channel 1 in a front-to-back order, and a lifting mechanism 5 is arranged between the cleaning mechanism 4 and the river channel 1, the cleaning mechanism 4 is used to block the garbage in the river channel 1, and the lifting mechanism 5 is used to salvage the garbage.

[0036] A barrier wall 2 is provided in the river channel 1;

[0037] A flow limiting mechanism 3 is arranged on the barrier wall 2, and the flow limiting mechanism 3 is used to control the flow of water;

[0038] A cleaning mechanism 4 is arranged in the river channel 1, and is used to block garbage in the water body;

[0039] The lifting mechanism 5 is arranged in the river channel 1, and is used for salvaging garbage in the water body.

[0040] The flow limiting mechanism 3 includes a through slot 31 penetrating through one side of the barrier wall 2 and a driving assembly 32 arranged on the barrier wall 2. A baffle 34 is connected to the through slot 31 through a rotating shaft 33. One end of the rotating shaft 33 penetrates the through slot 31 and extends to the outside of the barrier wall 2. One end of the rotating shaft 33 is fixedly connected to a gear 35, and the gear 35 is movably connected to the driving assembly 32. The sloping plate 42 is used to block the garbage in the water body, so that the garbage is intercepted on one side of the sloping plate 42. Some garbage will move to one side along the surface of the sloping plate 42, and some garbage will adhere to the sloping plate 42. When the attached garbage needs to be cleaned, the first motor 321 is turned on to drive the first screw rod 322 to rotate, thereby driving the connecting block 323 to move, and then driving the rack 324 to move. After that, the meshing transmission between the rack 324 and the gear 35 is used to drive the gear 35 to rotate, and then the baffle 34 is driven to rotate through the rotating shaft 33, so as to change the size of the water flow.

[0041] The driving assembly 32 includes a first motor 321 fixedly connected to the top of the barrier wall 2. The first motor 321 is a three-phase asynchronous motor, controlled by an external control program, and electrically connected to an external power supply. A protective cover is also provided on the outside of the entire driving assembly 32. The output end of the first motor 321 is fixedly connected to a first screw rod 322, and a connecting block 323 is threadedly connected to the first screw rod 322. A rack 324 is fixedly connected to the connecting block 323, and the rack 324 is meshed with a gear 35.

[0042] The connection block 323 is slidably connected to the barrier wall 2 , a support block 6 is fixedly connected to the top of the barrier wall 2 , and the support block 6 is rotatably connected to the first screw rod 322 .

[0043] Embodiment 2

[0044] Based on Example 1, see Figure 1 and Figure 4-Figure 6 shown.

[0045] The cleaning mechanism 4 includes a folding plate 41 arranged in the middle of the river channel 1, and an inclined plate 42 is fixedly connected to the folding plate 41, and a first through hole 43 is penetrated on one side of the inclined plate 42, and a transverse plate 44 is fixedly connected to the inclined plate 42, and a second through hole 45 is penetrated on one side of the transverse plate 44, and the transverse plate 44 is fitted between the river channel 1, and a push plate 47 is connected to the folding plate 41 through a moving component 46, and a protrusion 48 is fixedly connected to the push plate 47, and the protrusion 48 is adapted to the first through hole 43. When cleaning the garbage on the inclined plate 42, the second motor 461 is turned on, and then the second motor 461 drives the second screw rod 463 to rotate, thereby driving the moving seat 464 to move, and then the push rod 465 drives the card seat 466 to move along the straight rod 9, thereby driving the push plate 47 to move through the connecting plate 462, so that the protrusion 48 is inserted into the first through hole 43, so that the protrusion 48 is used to apply a thrust to the attached garbage, so that the garbage is separated from the inclined plate 42. Since the protrusion 48 is blocked in the first through hole 43, the water flow cannot pass through the first through hole 43, and can only pass through the second through hole 45. Therefore, under the action of the water flow, the garbage will move to one side. Afterwards, the second motor 461 and the second screw rod 463 cooperate to drive the push plate 47 to reset, so that the protrusion 48 withdraws from the first through hole 43, and then the water flow can pass through the first through hole 43 again.

[0046] The folding plate 41 is fixedly connected to a first fixing plate 7 , the first fixing plate 7 is fixedly connected to a second fixing plate 8 , and the second fixing plate 8 is fixedly connected to a straight rod 9 .

[0047] The moving component 46 includes a second motor 461 fixedly connected to the first fixed plate 7 and a connecting plate 462 fixedly connected to the push plate 47. The second motor 461 is a three-phase asynchronous motor, and is controlled by an external control program and electrically connected to an external power supply. A protective cover is also provided on the outside of the entire moving component 46. A second screw rod 463 is fixedly connected to the second motor 461, and the second screw rod 463 is rotationally connected to the first fixed plate 7. A moving seat 464 is threadedly connected to the second screw rod 463, and a push rod 465 is fixedly connected to the moving seat 464. A clamping seat 466 is fixedly connected to the top of the connecting plate 462, and the clamping seat 466 and the push rod 465 are slidably connected, and the connecting plate 462 is slidably connected to the straight rod 9.

[0048] A support rod 10 is fixedly connected to the inclined plate 42. The support rod 10 is provided to facilitate supporting the push plate 47. The support rod 10 is slidably connected to the push plate 47. A third through hole 11 is penetrated through one side of the push plate 47. The third through hole 11 facilitates the passage of water. The height of the inclined plate 42 is greater than that of the push plate 47.

[0049] Embodiment 3

[0050] Based on Example 1, see Figure 4 and Figure 6 shown.

[0051] The lifting mechanism 5 includes a mounting plate 51 fixedly connected to the transverse plate 44, a winding device 52 is arranged on the mounting plate 51, and the winding device 52 is connected to a salvage plate 54 through a steel cable 53, and the salvage plate 54 is slidably connected to the transverse plate 44 and the inclined plate 42. When the garbage on the salvage plate 54 reaches a certain amount, the salvage plate 54 is driven to rise by the cooperation of the winding device 52 and the steel cable 53, so that the garbage is salvaged by the salvage plate 54, so that people can clean up the garbage.

[0052] Embodiment 4

[0053] In combination with Embodiment 1, Embodiment 2 and Embodiment 3, see Figure 1-Figure 6 shown.

[0054] The sloping plate 42 is used to block and intercept garbage in the water, thereby preventing the garbage from covering the aquatic plants, and the moving component 46 and the water flow can be used together to clean up the garbage attached to the sloping plate 42 for subsequent cleaning.

[0055] The working principle of the present invention is as follows: a flow limiting mechanism 3 and a cleaning mechanism 4 are arranged in a river channel 1 in a front-to-back order, and a lifting mechanism 5 is arranged between the cleaning mechanism 4 and the river channel 1, and the cleaning mechanism 4 is located in front of the aquatic plant area.

[0056] First, the inclined plate 42 is used to block the garbage in the water body, so that the garbage is intercepted on one side of the inclined plate 42 , and some of the garbage will move to one side along the surface of the inclined plate 42 , while some of the garbage will adhere to the inclined plate 42 .

[0057] When it is necessary to clean the attached garbage, the first motor 321 is turned on to drive the first screw rod 322 to rotate, thereby driving the connecting block 323 to move, and then driving the rack 324 to move. After that, the meshing transmission between the rack 324 and the gear 35 is used to drive the gear 35 to rotate, and then the baffle 34 is driven to rotate through the rotating shaft 33, so as to change the size of the water flow; after that, the second motor 461 is turned on, and then the second motor 461 drives the second screw rod 463 to rotate, thereby driving the moving seat 464 to move, and then the push rod 465 drives the card seat 466 to move along the straight rod 9, so that through The connecting plate 462 drives the push plate 47 to move, so that the protrusion 48 is inserted into the first through hole 43, so that the protrusion 48 applies a thrust to the attached garbage, so that the garbage is separated from the inclined plate 42. Since the protrusion 48 is blocked in the first through hole 43, the water flow cannot pass through the first through hole 43, and can only pass through the second through hole 45. Therefore, under the action of the water flow, the garbage will move to one side. Afterwards, the second motor 461 and the second screw rod 463 cooperate to drive the push plate 47 to reset, so that the protrusion 48 withdraws from the first through hole 43, and then the water flow can pass through the first through hole 43 again.

[0058] Afterwards, when the garbage on the salvage plate 54 reaches a certain amount, the cooperation of the winding device 52 and the steel cable 53 is used to drive the salvage plate 54 to rise, so that the garbage can be salvaged by the salvage plate 54, so that people can clean up the garbage.

[0059] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
