[0001] The present invention belongs to the technical field of ecological buffer zones, and in particular relates to an ecological buffer zone for ecological restoration and a construction method thereof. Background Art

[0002] The ecological buffer zone is a water ecological governance measure and an important ecological space for rivers and lakes. It is of great significance in blocking or slowing down the direct interference of human activities on rivers and lakes, protecting the biodiversity of rivers and lakes, and reducing non-point source pollutants entering rivers and lakes.

[0003] The ecological buffer zones in the existing technology are relatively simple and are mostly constructed by planting plants. The plant roots play a role in preventing and consolidating the soil, thereby reducing soil loss. However, for water bodies that have been eutrophicated and have a large number of aquatic plants such as algae and duckweed, the ecological buffer zones constructed only by planting plants do not have the function of cleaning and purifying the water body and cannot play a role in repairing the ecological environment of the water body. Therefore, it is an urgent problem to provide an ecological buffer zone for ecological restoration and a construction method thereof. Summary of the Invention

[0038] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] like Figure 1-4 As shown, an ecological buffer zone for ecological restoration includes a buffer zone 3 located between a river zone 1 and a farmland zone 2. The side of the buffer zone 3 close to the river zone 1 is a slope surface. The buffer zone 3 is planted with a herbaceous plant layer, a shrub layer, and a tree layer. A plurality of water channels 10 are opened along the slope surface. The buffer zone 3 also includes:

[0044] Drainage and irrigation components 9, used to drain the water inside the collection and storage component 5 and irrigate the slope surface;

[0045] The flushing member 11 is used to flush the position squeezed by the squeezing component 6 on the suction fishing component 4 .

[0046] It should be noted that, in this embodiment, the aquatic plants include but are not limited to algae and duckweed; duckweed belongs to the Azolla family of ferns, floats on the water surface, and is an excellent aquatic feed plant and a famous green manure plant.

[0047] Preferably, the suction fishing assembly 4 includes four rotating rollers 41, a conveyor belt body 43 sleeved on the four rotating rollers 41 to form a circulating loop, an adsorption member 44 provided on the outer surface of the conveyor belt body 43, a guide roller 42 provided between the slope surface of the river channel area 1 and the buffer zone area 3 to guide the conveyor belt body 43 and the adsorption member 44 and in contact with the outer surface of the adsorption member 44, a support frame 46 for supporting and fixing the rotating rollers 41, and a servo motor 45 for driving the rotating rollers 41 to rotate;

[0048] The conveyor belt body 43 is supported and guided by the rotating roller 41 and the guide roller 42 to form upper and lower slope sections, a vertical extrusion section, and two vertical adsorption and capture sections extending into the river channel area 1.

[0049] It should be noted that the adsorption member 44 is any one of a porous silica pad and a sponge pad.

[0050] Preferably, the collection and storage component 5 includes a collection frame 51, a storage box 52, and a water tank 53 connected in sequence. A conveying pipe 54 is provided between the collection frame 51 and the storage box 52. One end of the conveying pipe 54 extends to the interior of the storage box 52 and is provided with a plurality of drainage holes. A filter element 55 for filtering aquatic plants is provided below the conveying pipe 54 inside the storage box 52. A sealing cover is detachably connected to the top of the storage box 52, and one side of the collection frame 51 is in contact with the vertical extrusion section of the conveyor belt body 43.

[0051] Preferably, the extrusion assembly 6 includes a plurality of round rollers 61 rotatably connected to the inside of the collection frame 51 and in contact with the adsorption member 44, a second support frame 62 provided on the slope surface, a connecting frame 63 rotatably connected to the second support frame 62, an extrusion plate 64 and a water receiving bucket 65 respectively provided at the upper and lower ends of the connecting frame 63, and a power assembly for driving the connecting frame 63 to rotate, and an elastic member is provided between the second support frame 62 and the connecting frame 63;

[0052] It should be noted that, in this embodiment, the elastic member is a torsion spring, which is used to drive the connecting frame 63, the extrusion plate 64 and the water receiving bucket 65 to reset.

[0053] A brush is provided inside the collecting frame 51 between two adjacent round rollers 61;

[0054] The power assembly includes a delivery pump 66 disposed inside the water tank 53, a drainage pipe 67 connected to the drainage port of the delivery pump 66, and several injection water pipes 68 connected to the drainage pipe 67. The drainage port of the injection water pipe 68 is connected to a booster nozzle.

[0055] When in use, the servo motor 45 drives the rotating roller 41 to rotate, thereby conveying the conveyor belt 43 and the adsorption member 44. The adsorption member 44 can adsorb aquatic plants, or the aquatic plants can be adsorbed and adhered to the adsorption member 44. During the transmission of the adsorption member 44, the delivery pump 66 starts to extract the water inside the water storage tank 53, and delivers it to the spray water pipe 68 through the drainage pipe 67, and sprays it to the water receiving bucket 65 through the booster nozzle. Under the impact of the water flow, the connecting frame 63 drives the extrusion plate 64 to rotate together. The extrusion plate 64 rotates toward the round roller 61 and squeezes the adsorption member 44 together with the round roller 61, thereby squeezing out water and aquatic plants. During the transmission of the adsorption member 44, the aquatic plants on the adsorption member 44 can also be cleaned by a brush. Then the aquatic plants and the water flow fall into the collection frame 51 together and are transported to the storage box 52 through the delivery pipe 54. After being filtered by the filter element 55, the aquatic plants are at the top of the filter element 55, and the water is transported to the water storage tank 53 for storage.

[0056] Preferably, the drainage and irrigation member 9 includes an irrigation main pipe connected to the drainage pipe 67, and a plurality of irrigation branch pipes connected to the irrigation main pipe and laid on the slope surface;

[0057] The flushing member 11 includes a main flushing pipe connected to the drainage pipe 67 and a plurality of branch flushing pipes connected to the main flushing pipe and extending into the interior of the collection frame 51. The branch flushing pipes are used to flush the area squeezed by the squeezing plate 64 and the round roller 61 on the adsorption member 44, so as to flush the aquatic plants on the adsorption member 44.

[0058] The drainage and irrigation component 9, the main flushing pipeline and each irrigation branch pipeline are all provided with a switch valve.

[0059] Preferably, the liquid level detection component includes an upper liquid level sensor 7 and a lower liquid level sensor 8 provided inside the collection and storage component 5;

[0060] When the lower liquid level sensor 8 detects that the amount of water stored in the collection storage component 5 is low, the adsorption and fishing component 4 is operated and squeezed by the squeezing component 6 to replenish the water in the collection storage component 5;

[0061] When the upper liquid level sensor 7 detects that the amount of water stored in the collection and storage component 5 is at a high liquid level, the water in the collection and storage component 5 is discharged through the irrigation branch pipe.

[0062] It should be noted that, in this embodiment, initially, the staff can manually add the amount of water stored in the collection and storage component 5 (water tank 53) until the amount is greater than or equal to the low liquid level.

[0063] Preferably, the front and rear sides of the slope section below the conveyor belt body 43 correspond to two water channels 10 respectively. The water poured by the water receiving bucket 65 will flow to the slope section below the conveyor belt body 43, and then flow into the water channel 10 along the slope section or directly into the river area 1. The slope surface is provided with 12 for detecting the moisture content of the soil, and at least one irrigation branch pipe is provided above each of the water channels 10.

[0064] When draining the water inside the collection and storage assembly 5, the water inside the collection and storage assembly 5 can be drained by opening the switch valve of the irrigation branch pipe above the water channel 10 when the soil moisture content is higher than the standard value; and by opening the switch valve on the irrigation branch pipe that can irrigate the soil when the soil moisture content is lower than the standard value, thereby irrigating the soil with the water discharged from the irrigation branch pipe.

[0065] It should be noted that the standard value of soil moisture content is determined based on actual usage.

[0066] A method for constructing an ecological buffer zone for ecological restoration, comprising the following specific steps:

[0067] Step 1: Planting herbs, shrubs, and trees in the buffer zone 3 to obtain a herbaceous plant layer, a shrub layer, and a tree layer;

[0068] Step 2: A plurality of water channels 10 are opened along the slope of the buffer zone 3, and a suction fishing assembly 4, a collection and storage assembly 5, a squeezing assembly 6, a drainage and irrigation component 9, and a flushing component 11 are installed. One side of the suction fishing assembly 4 extends into the river channel 1. The portion of the suction fishing assembly 4 extending into the river channel 1 can be used to absorb and capture aquatic plants in the water.

[0069] Step three: The adsorption and fishing component 4 adsorbs, captures and transports the aquatic plants to the interior of the collection and storage component 5. The collection and storage component 5 classifies and collects the stored aquatic plants for recycling to be used as fertilizer for herbs, shrubs and trees.

[0070] With the impact of waves, aquatic plants in the water will gather towards the shore, and then the aquatic plants can be captured and transported to the collection and storage component 5 through the adsorption and fishing component 4, which can clean up a lot of aquatic plants in the water, purify the water body, and benefit the survival and reproduction of other farmed organisms such as fish and shrimp in the water. The aquatic plants collected and stored by the collection and storage component 5 can be taken out regularly by staff, and the aquatic plants can be processed and used as fertilizers for herbs, shrubs, and trees, thereby realizing the ecological restoration of the water environment.

[0071] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
