Description

Technical Field

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

[0002] Coastal wetlands refer to the transition zone between terrestrial ecosystems and marine ecosystems. The lower limit of coastal wetlands is 6 meters below sea level, and the upper limit is freshwater or brackish water lakes and swamps connected to inland river basins above the high tide line, as well as sections of rivers flowing into the sea that cannot be reached by seawater upstream. Equivalent terms include coastal wetlands, coastal wetlands or coastal wetlands. Coastal wetlands are often affected by the interaction of human activities and biological effects. After a period of time, coastal wetlands will form varying degrees of damage in part or the entire area, including wetland eutrophication and wetland salinization. The intuitive phenomenon is that the wetlands lack water or biodiversity is destroyed, which will not only affect the ecological diversity of the wetlands themselves, but will also induce a series of environmental problems in the long run.

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.

[0051] 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.

[0052] Example 3:

[0053] Reference Figures 1-6 、 Figure 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.

[0054] The linkage part includes a positioning shell 11 rotatably connected to the sleeve 8, and a ventilation groove is provided on the positioning shell 11, wherein a positioning plate 1101 is fixedly connected to the end of the positioning shell 11 away from the sleeve 8, and the positioning plate 1101 is rotatably connected to the sliding frame 703.

Due to the high water content of wetland soil, the auger When the dragon rod 10 extracts and transports the soil, the soil becomes granular or muddy due to the squeezing of the auger rod 10. During the continuous transportation process, the granular or muddy soil is discharged from the sleeve 8 through the filter cylinder 9 and the strip groove 14, while the hard objects such as stones in the soil cannot be discharged from the filter cylinder 9 due to their large volume, thereby realizing the separation of soil and stones. The separated stones are transported 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.

[0056] Example 4:

[0057] Reference Figure 1 、 Figure 3-Figure 6 、 Figure 8-Figure 9 、 Figures 11-18 and Figure 20 , which is basically the same as the first embodiment, is preferably a specific implementation plan for spraying the repair liquid on the soil and dissipating the heat of the second motor 1102.

[0058] The injection part includes: a telescopic airbag 13, which is fixedly connected to the positioning frame 12, and the telescopic airbag 13 is sleeved on the sleeve 8, wherein a snap ring 1310 is rotatably connected to the telescopic airbag 13, and the snap ring 1310 is clamped on the limit strip 708, and the end of the telescopic airbag 13 away from the positioning frame 12 is against the limit strip 708; an outlet pipe 1301 fixedly connected to the telescopic airbag 13, and a one-way valve is fixedly sleeved on the outlet pipe 1301, wherein the outlet end of the outlet pipe 1301 is fixedly connected to the There is a liquid storage tank 1302, which is fixedly mounted on the screw rod 705. The screw rod 705 is provided with an opening connected to the cavity of the liquid storage tank 1302; a piston plate 1303 is arranged in the liquid storage tank 1302 and is slidably connected to the screw rod 705, wherein the piston plate 1303 is located between the cavity of the liquid storage tank 1302 and the outlet end of the outlet pipe 1301, and a spring 1311 is mounted on the screw rod 705. The two ends of the spring 1311 are respectively connected to the liquid storage tank 1302 and the piston plate. The plate 1303 is offset; a liquid supply pipe 1304 is fixedly connected to the cavity of the liquid storage tank 1302, and one end of the liquid supply pipe 1304 away from the liquid storage tank 1302 passes through the positioning shell 11 and is fixedly connected to the liquid collecting shell 1305, wherein the liquid collecting shell 1305 is rotatably connected to the auger rod 10, and the auger rod 10 is provided with a liquid inlet connected to the liquid collecting shell 1305, and the auger rod 10 is provided with a liquid channel connected to the liquid inlet and the liquid outlet; the air inlet pipe 1306 is fixedly connected to the extension On the deflating airbag 13, a one-way valve is fixedly sleeved on the air intake pipe 1306, wherein the air intake end of the air intake pipe 1306 is fixedly connected to an air intake cover 1307, and the side of the air intake cover 1307 away from the air intake pipe 1306 is connected to the inner cavity of the positioning shell 11, and the end of the telescopic airbag 13 away from the positioning frame 12 is fixedly connected to a slider 1308, and the slider 1308 is slidably connected to a guide frame 1309 fixedly connected to the vehicle frame 2, which is used to limit the telescopic airbag 13 to prevent it from deflecting when it is deflated.

[0059] Specifically, when the sleeve 8 moves, the limit bar 708 on its surface moves driven by the sleeve 8, and the limit bar 708 squeezes the telescopic airbag 13 during the movement, so that the gas inside the telescopic airbag 13 is 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 moving, the piston plate 1303 squeezes the spring 1311 and the repair liquid inside the liquid storage tank 1302, so that the repair liquid is discharged through the opening on the screw rod 705 and the liquid supply pipe 1304. Part of the repair liquid flows into the injection channel through the opening of the screw rod 705 and then enters the cavity of the positioning seat 704, and the repair liquid inside the cavity flows to the nozzle 6 through the telescopic tube 5 and The repair liquid is sprayed out, which can be injected into the soil around the drill rod 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, thereby realizing the repair of the transported and separated soil. In addition, the drill rod 4 and the sleeve 8 continue to penetrate into the soil, and can repair the soil at different depths, thereby increasing the repair range. After the soil injection repair is completed, the staff uses the driving part to reset the drill rod 4 and the sleeve 8. During the resetting process of the sleeve 8, the telescopic airbag 13 is stretched. At this time, the negative pressure inside the telescopic airbag 13 draws the gas inside the positioning shell 11, thereby realizing ventilation inside the positioning shell 11, thereby dissipating heat for the second motor 1102.

[0060] Embodiment 5:

[0061] Reference Figure 2 , which is basically the same as the first embodiment, is preferably a specific implementation plan for adjusting the angle of the frame 2.

[0062] 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 , and the 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 an axle pin.

[0063] 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 frame 2 to move, and the angle of the frame 2 can be adjusted. By adjusting the angle of the frame 2, the injection direction and diffusion range of the repair fluid can be effectively controlled.

[0064] 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 frame 2 to move, and the angle of the frame 2 can be adjusted. By adjusting the angle of the frame 2, the injection direction and diffusion range of the repair liquid can be effectively controlled.

[0065] After the angle adjustment of the frame 2 is completed, the staff uses the 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 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 adjusting the drill rod 4 and the sleeve 8. In addition, 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.

[0066] 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, and the two positioning shells 11 drive the two sleeves 8 to move when moving, so that the sleeves 8 move into the soil at the same time as the drill rod 4. In the process of the positioning shell 11 driving the sleeve 8 to move, the output end of the second motor 1102 drives the auger rod 10 to rotate. The auger rod 10 and the sleeve 8 rotate in opposite directions to extract the soil. Since the wetland soil has a large water content, the auger rod When 10 is extracting and transporting soil, the soil becomes granular or muddy due to the squeezing of the auger rod 10. During the continuous transportation process, the granular or muddy soil is discharged from the sleeve 8 through the filter cylinder 9 and the strip groove 14, while the hard objects such as stones in the soil cannot be discharged from the filter cylinder 9 due to their large volume, thereby realizing the separation of soil and stones. The separated stones are transported 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.

[0067] During the movement of the sleeve 8, the limit bar 708 on its surface moves driven by the sleeve 8. During the movement, the limit bar 708 squeezes the telescopic airbag 13, so that the gas inside the telescopic airbag 13 is 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 moving, the piston plate 1303 squeezes the spring 1311 and the repair liquid inside the liquid storage tank 1302, so that the repair liquid is discharged through the opening on the screw rod 705 and the liquid supply pipe 1304. Part of the repair liquid flows into the injection channel through the opening of the screw rod 705 and then enters the cavity of the positioning seat 704, and the repair liquid inside the cavity flows to the nozzle 6 through the telescopic tube 5 and is sprayed out , it is possible to inject repair liquid into the soil around the drill rod 4, and 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, thereby realizing the repair of the transported and separated soil, and the drill rod 4 and the sleeve 8 continue to penetrate into the soil, which can repair the soil at different depths, thereby increasing the repair range. After the soil injection repair is completed, the staff uses the driving part to reset the drill rod 4 and the sleeve 8. During the resetting 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, thereby realizing ventilation inside the positioning shell 11, thereby dissipating heat for the second motor 1102.
