Description

Technical Field

[0001] The present invention relates to the technical field of wetland soil remediation, and particularly to an ecological remediation device for damaged coastal wetlands. Background Art

[0002] Coastal wetlands refer to the transitional zone between terrestrial and marine ecosystems. The lower limit of coastal wetlands is 6 meters below sea level, and the upper limit is the freshwater or brackish water lakes connected to the inner river basin above the high tide line and the river sections of the inland rivers that the seawater cannot reach. Equivalent terms include coastal wetlands, coastal zone wetlands, or coastal wetlands, etc. Due to the mutual influence of human activities and biological effects, coastal wetlands will be damaged to varying degrees in some or all areas after a period of time, including wetland eutrophication, wetland salinization, etc. The intuitive phenomenon is the lack of water in the wetland or the destruction of biodiversity, which will not only affect the ecological diversity of the wetland itself, but also induce a series of environmental problems in the long run.

[0003] The existing restoration methods for damaged coastal wetlands usually include physical methods, chemical methods, and biological methods. In physical methods, incineration methods, solidification and stabilization methods, etc. are used; in chemical methods, chemical remediation liquids are injected into the soil to improve the internal environment of the soil; biological methods involve introducing organisms such as bacteria, fungi, yeast, plants, etc. into the polluted area, and through their natural metabolic capabilities, decomposing and degrading toxic and harmful substances.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Embodiment 1: Refer to Figures 1 - 19, An ecological restoration device for damaged coastal wetlands, including a vehicle body 1, and also including: a frame 2, rotatably connected to the vehicle body 1, and an adjusting member for driving the frame 2 to rotate is provided on the vehicle body 1. Among them, a drill rod 4 is installed on the vehicle body 1, and at least two channels are opened in the drill rod 4. The number of channels is between two and four, and here it is preferably four. Telescopic tubes 5 are provided in all four channels. The liquid outlet end of the telescopic tube 5 is fixedly connected to a spray head 6, and the spray head 6 is fixedly connected to the drill rod 4. A driving member is provided in the vehicle body 1. When the driving member works, the drill rod 4 drives the spray head 6 to move and rotate; at least one set of sleeves 8 installed on the vehicle body 1, the number of sleeves 8 is between one and two, and here it is preferably two. One end of the sleeve 8 away from the vehicle body 1 is fixedly connected to a drill bit 16. The drill bit 16 is of a hollow structure and is used for soil extraction. Three to six strip-shaped grooves 14 are opened on the sleeve 8, and here it is preferably six, which is convenient for soil to be discharged from the sleeve 8. A slag discharge groove 15 is opened on the sleeve 8. The slag discharge groove 15 is located between the strip-shaped groove 14 and the third gear 707 and is used for discharging hard objects such as stones inside the soil. A filter cylinder 9 is fixedly installed in the sleeve 8. The filter cylinder 9 is made of stainless steel. Among them, an auger rod 10 is provided in the filter cylinder 9, and a number of liquid outlet holes are opened on the auger rod 10. A linkage member is provided on the filter cylinder 9. When the drill rod 4 moves, the filter cylinder 9 moves synchronously with the drill rod 4; a positioning frame 12 is fixedly installed on the frame 2, and an injection part is provided on the positioning frame 12. When the sleeve 8 moves, the injection part contracts and drives the repair liquid to flow to the spray head 6 and the auger rod 10.

[0023] Specifically, through the cooperation of the driving member and the linkage member, the positions of the drill rod 4 and the sleeve 8 can be adjusted to achieve the repair of soils at different depths. At the same time, during the repair process, the soil and stones can be separated, improving the diffusion range and quality of the repair liquid. And when the drill rod 4 and the sleeve 8 are reset after the repair is completed, the negative pressure inside the expansion airbag 13 in the injection part can achieve air exchange for the positioning shell 11, thereby playing a role in dissipating heat for the second motor 1102 and extending the service life of the second motor 1102.

[0024] Embodiment Two: Refer to Figures 2 - 11 、 Figures 13 - 15 and Figure 20 , which is basically the same as Embodiment One. Preferably, it is a specific implementation plan for the repair of soils at different depths.

[0025] The driving member includes: a first motor 7, which is fixedly installed in the frame 2, and the output end of the first motor 7 is fixedly connected to the first gear 701, wherein the first gear 701 is meshed with the second gear 702, and the second gear 702 is slidably connected to the sliding frame 703 fixedly connected to the drill rod 4; a positioning seat 704 fixedly connected to the second gear 702, and a cavity is provided inside the positioning seat 704, wherein the cavity of the positioning seat 704 is connected to the liquid inlet end of the telescopic tube 5, and a screw rod 705 is rotatably connected in the positioning seat 704, and the screw rod 705 is threadedly connected to the drill rod 4, and the end of the screw rod 705 away from the drill rod 4 is fixedly connected to the fixing frame 706, fixed The frame 706 is fixedly connected to the frame 2, and an injection channel is provided on the screw rod 705, and the injection channel is connected to the cavity of the positioning seat 704; two groups of third gears 707 are movably mounted on the sleeve 8, and the third gear 707 is engaged with the second gear 702, wherein at least two groups of limit bars 708 are fixedly connected to the sleeve 8, and the number of limit bars 708 is between two and four groups, and four groups are preferably used here. The limit bar 708 is slidably connected to the third gear 707, and a limit groove 709 is provided on the third gear 707. A limit block 710 fixedly connected to the positioning frame 12 is slidably connected in the limit groove 709 for limiting the third gear 707.

[0026] Specifically, after the angle adjustment of the frame 2 is completed, the staff uses the external control switch to start the first motor 7, and the output end of the first motor 7 drives the first gear 701 to rotate. When the first gear 701 rotates, it drives the second gear 702 to rotate. When the second gear 702 rotates, it drives the sliding frame 703, the positioning seat 704 and the two third gears 707 to rotate. When the sliding frame 703 rotates, it drives the drill rod 4 to rotate. When the drill rod 4 rotates on the surface of the screw rod 705, it drives the sliding frame 703 to move. When the sliding frame 703 moves in the inner cavity of the second gear 702, it drives the positioning plate 1101 to move. At the same time, the two third gears 707 drive the two sleeves 8 to rotate when they rotate, thereby realizing the adjustment of the drill rod 4 and the sleeve 8, and the positioning seat 704 drives the telescopic tube 5 to rotate when it rotates, so that the telescopic tube 5 rotates synchronously with the drill rod 4.

[0027] Example 3: Reference Figures 1 - 6 、 Figures 11 - 12 and Figures 14 - 18 , which is basically the same as the first embodiment, is preferably a specific implementation plan for adjusting the position of the sleeve 8 and driving the auger rod 10 to separate the soil and internal stones.

[0028] The linkage member includes a positioning shell 11 rotatably connected to the sleeve 8. A ventilation groove is provided on the positioning shell 11. Specifically, one end of the positioning shell 11 away from the sleeve 8 is fixedly connected to a positioning plate 1101. The positioning plate 1101 is rotatably connected to the sliding frame 703. A limiting ring is fixedly sleeved on the sliding frame 703. An annular groove is provided in the positioning plate 1101. The limiting ring is rotatably connected in the annular groove to limit the sliding frame 703. A second motor 1102 is fixedly installed in the positioning shell 11. The output end of the second motor 1102 is fixedly connected to the auger rod 10.

[0029] Specifically, when the sliding frame 703 in the driving member drives the positioning plate 1101 to move, the positioning plate 1101 drives the two positioning shells 11 to move. When the two positioning shells 11 move, they drive the two sleeves 8 to move, so that the sleeves 8 move into the soil simultaneously with the drill rod 4. During the process that the positioning shell 11 drives the sleeve 8 to move, the output end of the second motor 1102 drives the auger rod 10 to rotate. The reverse rotation of the auger rod 10 and the sleeve 8 can extract the soil. Since the wetland soil has a large water content, when the auger rod 10 extracts and conveys the soil, affected by the extrusion of the auger rod 10, the soil becomes granular or muddy. During the continuous conveying process, the granular or muddy soil is discharged from the sleeve 8 through the filter cylinder 9 and the strip-shaped groove 14. However, hard objects such as stones in the soil cannot be discharged from the filter cylinder 9 due to their large volume, realizing the separation of the soil and the stones. The separated stones are conveyed by the auger rod 10 and discharged to the ground through the slag discharge groove 15 on the surface of the sleeve 8, which can effectively prevent hard objects such as stones from hindering the diffusion of the repair liquid in the soil.

[0030] Embodiment 4: Refer to Figure 1 、 Figures 3 - 6 、 Figures 8 - 9 、 Figures 11 - 18 and Figure 20 , which is basically the same as Embodiment 1. Preferably, it is a specific implementation scheme for spraying the repair liquid on the soil and dissipating heat from the second motor 1102.

[0031] The injection part includes: a telescopic airbag 13 fixedly connected to the positioning frame 12. The telescopic airbag 13 is sleeved on the sleeve 8. Among them, a clamping ring 1310 is rotatably connected inside the telescopic airbag 13. The clamping ring 1310 is clamped on the limiting strip 708, and one end of the telescopic airbag 13 away from the positioning frame 12 abuts against the limiting strip 708; an air outlet pipe 1301 fixedly communicated with the telescopic airbag 13, and a one-way valve is fixedly sleeved on the air outlet pipe 1301. Among them, the air outlet end of the air outlet pipe 1301 is fixedly communicated with a liquid storage tank 1302. The liquid storage tank 1302 is fixedly sleeved on the lead screw 705, and an opening communicating with the cavity of the liquid storage tank 1302 is formed on the lead screw 705; a piston plate 1303 is arranged inside the liquid storage tank 1302 and is slidably connected to the lead screw 705. Among them, the piston plate 1303 is located between the cavity of the liquid storage tank 1302 and the air outlet end of the air outlet pipe 1301. A spring 1311 is sleeved on the lead screw 705, and both ends of the spring 1311 abut against the liquid storage tank 1302 and the piston plate 1303 respectively; a liquid supply pipe 1304 fixedly communicated with the cavity of the liquid storage tank 1302. One end of the liquid supply pipe 1304 away from the liquid storage tank 1302 penetrates through the positioning shell 11 and is fixedly communicated with a liquid collecting shell 1305. Among them, the liquid collecting shell 1305 is rotatably connected to the auger rod 10. An inlet port communicating with the liquid collecting shell 1305 is formed on the auger rod 10, and a liquid channel communicating with the inlet port and the outlet port is formed inside the auger rod 10; an air inlet pipe 1306 is fixedly communicated with the telescopic airbag 13, and a one-way valve is fixedly sleeved on the air inlet pipe 1306. Among them, the air inlet end of the air inlet pipe 1306 is fixedly communicated with an air inlet cover 1307. One side of the air inlet cover 1307 away from the air inlet pipe 1306 is communicated with the inner cavity of the positioning shell 11. One end of the telescopic airbag 13 away from the positioning frame 12 is fixedly connected with a slider 1308. A guide frame 1309 fixedly connected to the vehicle frame 2 is slidably connected to the slider 1308, which is used to limit the telescopic airbag 13 to prevent it from deflecting when contracting.

[0032] Specifically, during the movement of the sleeve 8, the limiting strip 708 on its surface moves under the drive of the sleeve 8. During the movement, the limiting strip 708 squeezes the telescopic airbag 13, causing the gas inside the telescopic airbag 13 to be discharged into the liquid storage tank 1302 through the air outlet pipe 1301. At this time, the air pressure inside the liquid storage tank 1302 pushes the piston plate 1303 to move. When the piston plate 1303 moves, it squeezes the spring 1311 and the repair liquid inside the liquid storage tank 1302, causing the repair liquid to be discharged through the opening on the lead screw 705 and the liquid supply pipe 1304. Part of the repair liquid flows into the injection channel through the opening of the lead screw 705 and then enters the cavity of the positioning seat 704. The repair liquid inside the cavity flows through the telescopic pipe 5 to the nozzle 6 and is sprayed out, enabling the injection of the repair liquid around the drill pipe 4. The repair liquid inside the liquid supply pipe 1304 enters the liquid channel inside the auger rod 10 through the liquid collecting shell 1305 and is discharged into the sleeve 8 through the liquid outlet holes, realizing the repair of the transported and separated soil. Moreover, as the drill pipe 4 and the sleeve 8 continuously penetrate deeper into the soil, the soil at different depths can be repaired, thereby increasing the repair range. After the soil injection repair is completed, the staff uses the driving member to reset the drill pipe 4 and the sleeve 8. During the reset process of the sleeve 8, the telescopic airbag 13 is stretched. At this time, the negative pressure inside the telescopic airbag 13 extracts the gas inside the positioning shell 11, realizing the ventilation inside the positioning shell 11, thereby dissipating heat from the second motor 1102.

[0033] Embodiment Five: Referring to Figure 2 , which is basically the same as Embodiment One. Preferably, it is a specific implementation scheme for adjusting the angle of the vehicle frame 2.

[0034] The adjusting member includes a hydraulic cylinder 3 rotatably connected to the vehicle body 1. The telescopic end of the hydraulic cylinder 3 is rotatably connected to the vehicle frame 2. One side of the vehicle frame 2 away from the telescopic end of the hydraulic cylinder 3 is rotatably connected to the vehicle body 1 through a pin.

[0035] Specifically, when repairing the soil, the staff uses an external control switch to start the hydraulic cylinder 3. The output end of the hydraulic cylinder 3 drives one side of the vehicle frame 2 to move, enabling the adjustment of the angle of the vehicle frame 2. By adjusting the angle of the vehicle frame 2, the injection direction and diffusion range of the repair liquid can be effectively controlled.

[0036] In the present invention, when repairing the soil, the staff uses an external control switch to start the hydraulic cylinder 3. The output end of the hydraulic cylinder 3 drives one side of the vehicle frame 2 to move, enabling the adjustment of the angle of the vehicle frame 2. By adjusting the angle of the vehicle frame 2, the injection direction and diffusion range of the repair liquid can be effectively controlled.

[0037] After the angle adjustment of the vehicle frame 2 is completed, the staff uses an external control switch to start the first motor 7. The output end of the first motor 7 drives the first gear 701 to rotate. When the first gear 701 rotates, it drives the second gear 702 to rotate. When the second gear 702 rotates, it drives the sliding frame 703, the positioning seat 704 and two third gears 707 to rotate. When the sliding frame 703 rotates, it drives the drill pipe 4 to rotate. When the drill pipe 4 rotates on the surface of the lead screw 705, it drives the sliding frame 703 to move. When the sliding frame 703 moves inside the cavity of the second gear 702, it drives the positioning plate 1101 to move. At the same time, when the two third gears 707 rotate, they drive the two sleeves 8 to rotate, realizing the adjustment of the drill pipe 4 and the sleeves 8. Moreover, when the positioning seat 704 rotates, it drives the telescopic pipe 5 to rotate, so that the telescopic pipe 5 rotates synchronously with the drill pipe 4.

[0038] When the sliding frame 703 in the driving member drives the positioning plate 1101 to move, the positioning plate 1101 drives the two positioning shells 11 to move. When the two positioning shells 11 move, they drive the two sleeves 8 to move, so that the sleeves 8 move into the soil interior simultaneously with the drill pipe 4. During the process that the positioning shells 11 drive the sleeves 8 to move, the output end of the second motor 1102 drives the auger rod 10 to rotate. The reverse rotation of the auger rod 10 and the sleeves 8 can extract the soil. Since the water content of the wetland soil is relatively large, when the auger rod 10 extracts and conveys the soil, affected by the extrusion of the auger rod 10, the soil becomes granular or muddy. During the continuous conveying process, the granular or muddy soil is discharged from the sleeves 8 through the filter cylinder 9 and the strip-shaped groove 14. However, hard objects such as stones in the soil cannot be discharged from the filter cylinder 9 due to their large volume, realizing the separation of the soil and the stones. The separated stones are conveyed by the auger rod 10 and discharged to the ground through the slag discharge groove 15 on the surface of the sleeves 8, which can effectively prevent hard objects such as stones from hindering the diffusion of the repair liquid in the soil.

[0039] During the movement of the sleeve 8, the limit strip 708 on its surface moves under the drive of the sleeve 8. During the movement of the limit strip 708, it squeezes the telescopic airbag 13, causing the gas inside the telescopic airbag 13 to be discharged into the liquid storage tank 1302 through the air outlet pipe 1301. At this time, the air pressure inside the liquid storage tank 1302 pushes the piston plate 1303 to move. When the piston plate 1303 moves, it squeezes the spring 1311 and the repair liquid inside the liquid storage tank 1302, causing the repair liquid to be discharged through the opening on the lead screw 705 and the liquid supply pipe 1304. Part of the repair liquid flows into the injection channel through the opening of the lead screw 705 and then enters the cavity of the positioning seat 704. The repair liquid inside the cavity flows through the telescopic pipe 5 to the nozzle 6 and is sprayed out, enabling the injection of the repair liquid around the drill pipe 4. The repair liquid inside the liquid supply pipe 1304 enters the liquid channel inside the auger rod 10 through the liquid collection shell 1305 and is discharged into the sleeve 8 through the liquid outlet holes, realizing the repair of the transported and separated soil. Moreover, as the drill pipe 4 and the sleeve 8 continuously penetrate into the soil, the soil at different depths can be repaired, thereby expanding the repair range. After the soil injection repair is completed, the staff uses the driving member to reset the drill pipe 4 and the sleeve 8. During the reset process of the sleeve 8, it stretches the telescopic airbag 13. At this time, the negative pressure inside the telescopic airbag 13 extracts the gas inside the positioning shell 11, realizing the air exchange inside the positioning shell 11, thereby dissipating heat from the second motor 1102.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
