Description

Technical Field

[0001] The invention belongs to the technical field of wetland ecological restoration, and in particular relates to an ecological restoration device for damaged coastal wetlands. Background Art

[0002] Coastal wetlands usually refer to the wetland ecological structure in the coastal area, which is a common wetland ecosystem. Due to the frequent interaction between human activities and biological effects, coastal wetlands will form different degrees of damage in part or the whole area after a period of time, including wetland eutrophication, wetland salinization, etc. The intuitive phenomenon is that the wetland lacks water or the biodiversity is destroyed, which will not only affect the ecological diversity of the wetland itself, but also induce a series of environmental problems in the long run. The existing methods for repairing damaged coastal wetlands usually include physical, chemical and biological methods. The physical method uses incineration and solidification stabilization methods, which require the installation of large-scale processing equipment, and the soil needs to be excavated and transported, and the overall cost of the repair process is relatively high. The chemical method injects chemical repair agents into the soil, but this kind of repair agent has certain toxicity, and may cause secondary pollution while repairing the soil. The biological method is to introduce bacteria, fungi, yeast, plants and other organisms into the polluted area, and through their natural metabolic ability, decompose and degrade toxic and harmful substances, and form substances that are harmless to the environment, thereby restoring the nutritional balance and ecological environment of the polluted soil. Therefore, the biological method is the most environmentally friendly, low-cost, and most suitable for wetland soil remediation.

[0003] However, when using existing biological methods, it is difficult to carry out targeted repairs based on the specific damage situation because the degree and type of damage in the same wetland area are different; and some existing ecological restoration devices are difficult to insert into the wetland soil when spraying the restoration agent, making it difficult to repair the underground soil.

[0047] It should be noted that, if initially, the infiltration component 10 is in a folded state, the spring 19 is in a compressed state, and the inner infiltration tube 18 is arranged in the outer infiltration tube 17, when the second hydraulic rod 11 drives the first fixed plate 14 to move downward, the driving rod 15 is driven, and the driving rod 15 drives the second fixed plate 16. Under the action of the second fixed plate 16 and the third fixed plate 8, the infiltration component 10 rotates with the third fixed plate 8 as the rotation center.

The number of the control holes 33 is the same as the number of the connecting ropes 29 and matches the position of the connecting ropes 29. The connecting ropes 29 are movable through the control holes 33. A control valve is provided in the control hole 33 to facilitate the control of the movement of the connecting ropes 29. When the second lower pressure plate 12 moves downward, the sleeve 13 and the first fixed plate 14 are driven downward. At this time, the control valve in the control hole 33 is closed, and the connecting rope 29 does not move. After the driving rod 15 drives the infiltration assembly 10 to unfold, the control valve in the control hole 33 is opened, and under the action of the spring 19, the connecting rope 29 is stretched by the inner infiltration tube 18.

[0050] The drill rod 1 has a plurality of through slots 34 for limiting the position, and the upper ends of the through slots 34 penetrate the upper wall of the drill rod 1.

[0051] It should be noted that, initially, the infiltration component 10 is in a folded state, and the baffle 36 blocks the entry and exit of the slot 35. When the infiltration component 10 needs to be unfolded, the first lower pressure plate 37 moves upward, driving the baffle 36 to move upward, and the baffle 36 moves upward along the through groove 34 to expose the slot 35, making it easier for the infiltration component 10 to extend through the slot 35 to the outside of the drill pipe 1.

[0053] The specific implementation is as follows:

[0054] The equipment is transported to the damaged coastal wetland that needs to be repaired. Initially, the infiltration component 10 is in a retracted state and arranged in the drill pipe 1. At this time, the spring 19 is in a compressed state, the inner infiltration tube 18 is arranged in the outer infiltration tube 17, and the baffle 36 blocks the ingress and egress of the slot 35. The drill pipe 1 is placed vertically. After the external drive shaft is connected to the connecting piece 40 by threaded connection or bolt connection, the external motor is connected to the drive shaft, which can drive the drill pipe 1 to rotate and enter the underground. The upper end of the drill pipe 1 is arranged on the ground. When the underground soil needs to be repaired, the first hydraulic rod 41 works to drive the first lower pressure plate 37 to move upward, and the first lower pressure plate 37 drives the baffle 36 to move. The baffle 36 moves upward along the through groove 34 to leak the slot 35, so that the infiltration component 10 can extend to the outside of the drill pipe 1 through the slot 35;

[0055] The second hydraulic rod 11 drives the second lower pressing plate 12 to move downward, the second lower pressing plate 12 drives the sleeve 13 to move downward, the sleeve 13 drives the first fixed plate 14 to move downward, when the first fixed plate 14 moves downward, the driving rod 15 is driven, the driving rod 15 drives the second fixed plate 16, the infiltration assembly 10 rotates with the third fixed plate 8 as the rotation center under the action of the second fixed plate 16 and the third fixed plate 8, and the multiple groups of infiltration assemblies 10 are in an unfolded state, similar to the unfolding of an umbrella;

[0056] When the second lower pressing plate 12 moves downward, the sleeve 13 and the first fixed plate 14 are driven downward. At this time, the control valve in the control hole 33 is closed, and the connecting rope 29 at the lower end of the control plate 32 does not move. The connecting rope 29 between the control plate 32 and the first fixed plate 14 is in a relaxed state. When the driving rod 15 drives the infiltration assembly 10 to unfold, the control valve in the control hole 33 is opened. Under the action of the spring 19, the connecting rope 29 is stretched by the inner infiltration tube 18. The spring 19 pushes the inner infiltration tube 18 to move outward along the outer infiltration tube 17. The inner infiltration tube 18 extends out of the outer infiltration tube 17, increasing the contact area with the underground soil, making it easier to spray the repair liquid on the underground soil.

[0057] According to the different underground soil pollution conditions, different repair liquids are transported to different delivery pipes 31 through external transport equipment, and transported to the guide hole 26 through the through hole 30. The repair liquid in the guide hole 26 enters the flexible connecting pipe 1 25, and enters the connecting pipe 2 24 through the flexible connecting pipe 1 25. A part of the repair liquid in the connecting pipe 24 enters the circulation cavity 20, and the other part enters the circulation cavity 1 22 through the connecting cavity 27. The control valve in the inner permeation hole 21 connected to the circulation cavity 20 is opened, and the control valve liquid in the outer permeation hole 23 connected to the circulation cavity 1 22 is opened, and the repair liquid is sprayed on the soil at this location;
