Description

Technical Field

[0001] This utility model relates to the field of river and lake ecological restoration technology, specifically a submerged plant root-sludge co-transplantation device based on buoyancy control. Background Technology

[0002] Submerged plants are an important component of lake ecosystems, playing an irreplaceable role in purifying water quality, stabilizing bottom sediment, inhibiting algal blooms, and maintaining biodiversity. Submerged plants play a vital role in aquatic ecological restoration, water purification, and the reconstruction of aquatic ecosystems. Their transplant survival rate directly affects the ecological restoration effect, and the coordinated protection of plant roots and surrounding bottom sediment during the transplanting process is particularly crucial. Existing methods and equipment for transplanting submerged plants have the following main shortcomings: Traditional manual transplanting (such as operation by divers or simple tool insertion) is inefficient, labor-intensive, and difficult to precisely control the integrity of the root system, especially in deep or turbid waters, making operation difficult and easily causing damage to plant roots and loss of bottom mud, resulting in unstable transplant survival rates; some existing mechanized transplanting equipment often cannot flexibly adapt to different water depth changes, resulting in limited operating range or the need for frequent adjustments. Most equipment only focuses on the plant itself and does not pay enough attention to the "original" bottom mud surrounding the roots, which easily causes bottom mud to be lost or separated from the roots during transplanting, damaging the rhizosphere microenvironment (microbial community, nutrients, physical support structure), seriously affecting the recovery and growth of plants after planting. Utility Model Content

[0003] The purpose of this invention is to provide a submerged plant root-soil co-transplantation device based on buoyancy control, which has the effect of efficient co-extraction and non-destructive preservation of roots and native sediment.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a submerged plant root-soil co-transplanting device based on buoyancy control, comprising a hollow chamber and a transplanting container disposed below it. The hollow chamber is equipped with a water pump and a drainage pump inside, and one end of the hollow chamber is provided with a water inlet pipe connected to the water inlet end of the water pump. The top of the hollow chamber is provided with a drainage pipe connected to the water outlet end of the drainage pump. The hollow chamber and the transplanting container are connected by an adjusting component. An installation frame is fixedly provided at the bottom of the hollow chamber, and two split cutting plates are slidably provided at the bottom of the installation frame. The opening and closing of the cutting plates are driven by a driving component.

[0005] A further feature of this invention is that the adjusting component includes an installation steel pipe and an adjusting steel pipe, the installation steel pipe is fixedly installed at the bottom of the hollow chamber, the adjusting steel pipe is fixedly installed at the top of the transplanting container, and the adjusting steel pipe is slidably connected to the installation steel pipe.

[0008] A further feature of this invention is that the bottom surface of the cutting plate is on the same plane as the bottom surface of the mounting frame, and the cutting end of the cutting plate is set as an inclined surface and a serrated titanium alloy blade is used.

[0009] A further feature of this invention is that the driving component includes a connecting frame, a mounting base, and a bidirectional lead screw. Two connecting frames are provided, and the connecting frame is fixedly installed on the outer side of the top of the cutting plate. The mounting base is fixedly installed in the middle of the top of the transplanting container. The top of the mounting base is rotatably connected to the middle of the bidirectional lead screw, and both ends of the bidirectional lead screw are threadedly connected to the top of the connecting frame.

[0012] A further feature of this invention is that a mounting bracket is fixedly provided on the side of the mounting plate, and a hanging ring is provided in the middle of the mounting bracket.

[0013] In summary, this utility model has the following beneficial effects: The efficient and non-destructive extraction and preservation of roots and native sediment, achieved through a sealed containment space formed by the cutting plate, allows for precise and simultaneous cutting around the target plant's roots, realizing the integrated columnar extraction of roots and in-situ sediment. This ensures that the native sediment surrounding the roots remains intact and does not scatter during lifting, transportation, and placement, maximizing the protection of the rhizosphere microenvironment and significantly improving transplant survival rates. The integrated buoyancy adjustment mechanism can quickly adjust the overall buoyancy of the device according to the target water depth, achieving stepless adaptation to water depth. The controllable buoyancy allows the device to be precisely positioned and stably suspended above the target transplant point in the water, creating the necessary conditions for precise placement and overcoming the challenges of operation in deep and turbid water. Replacing traditional manual divers' work, a single operation can complete the entire process of extraction, transportation, and placement of one or more plants. The operation process (cutting, lifting, transferring, and placement) can be controlled on the water surface or boat, avoiding the risks of personnel diving. It is particularly suitable for large-area, deep-water ecological restoration projects. Attached Figure Description

[0018] In this embodiment, preferably, the adjustment component includes a mounting steel pipe 103 and an adjustment steel pipe 201. The mounting steel pipe 103 is fixedly installed at the bottom of the hollow cabin 1, and the adjustment steel pipe 201 is fixedly installed at the top of the transplant container 2. The adjustment steel pipe 201 and the mounting steel pipe 103 are slidably connected. The sliding cooperation between the two can adjust the distance between the hollow cabin 1 and the transplant container 2 to adapt to operations under different water depth conditions. In this embodiment, preferably, the surface of the mounting steel pipe 103 is provided with a plurality of positioning holes 104, the top of the adjusting steel pipe 201 is provided with a positioning hole 202, and a positioning bolt 105 is installed between the corresponding positioning hole 104 and the positioning hole 202. By connecting the positioning bolt 105 with the corresponding positioning hole 104 and the positioning hole 202, the position of the adjusting steel pipe 201 and the mounting steel pipe 103 can be locked. In this embodiment, preferably, the inner side of the mounting frame 203 is provided with a sliding groove 204, and the side of the cutting plate 205 is fixedly provided with a sliding rail 206 that slides in cooperation with the sliding groove 204. The sliding cooperation between the sliding rail 206 and the sliding groove 204 plays a guiding and limiting role in the movement of the cutting plate 205. In this embodiment, preferably, the bottom surface of the cutting plate 205 is on the same plane as the bottom surface of the mounting frame 203, and the cutting end of the cutting plate 205 is set as an inclined surface and a serrated titanium alloy blade is used, which can adapt to different mud hardness and ensure that plants and surrounding mud can be extracted. In this embodiment, preferably, the driving component includes a connecting frame 207, a mounting base 208, and a bidirectional lead screw 209. Two connecting frames 207 are provided, and the connecting frames 207 are fixedly installed on the outer side of the top of the cutting plate 205. The mounting base 208 is fixedly installed in the middle of the top of the transplanting container 2. The top of the mounting base 208 is rotatably connected to the middle of the bidirectional lead screw 209, and both ends of the bidirectional lead screw 209 are threadedly connected to the top of the connecting frame 207. When the bidirectional lead screw 209 rotates, it can drive the two cutting plates 205 to open and close synchronously. In this embodiment, preferably, the driving component further includes a mounting shaft 2010, a first bevel gear 2011, a mounting plate 3, a rotating shaft 301, and a second bevel gear 303. The mounting shaft 2010 is fixedly mounted on one end of the bidirectional lead screw 209, the first bevel gear 2011 is fixedly mounted on one end of the mounting shaft 2010, the mounting plate 3 is fixedly mounted on one side of the hollow cabin 1, and the mounting plate 3 is rotatably connected to the rotating shaft 301. A rotating wheel 302 is fixedly mounted on the top end of the rotating shaft 301, and the second bevel gear 303 is fixedly mounted on the bottom end of the rotating shaft 301. The second bevel gear 303 is meshed with the first bevel gear 2011. The rotating wheel 302 can rotate the rotating shaft 301, thereby driving the second bevel gear 303 to rotate. Under the meshing cooperation of the second bevel gear 303 and the first bevel gear 2011, the bidirectional lead screw 209 is driven to rotate. In this embodiment, preferably, the surface of the rotating shaft 301 is provided with a locking screw 305, and the bottom end of the mounting plate 3 is fixedly provided with a locking frame 304. The surface of the locking frame 304 is provided with a through hole through which the locking screw 305 passes, and two locking nuts 306 are threadedly installed on the surface of the locking screw 305. The locking nuts 306 are located on both sides of the through hole. The position of the rotating shaft 301 can be locked by the cooperation between the locking screw 305 and the locking nuts 306, so as to prevent the rotating shaft 301 from rotating accidentally. In this embodiment, preferably, a mounting bracket 307 is fixedly provided on the side of the mounting plate 3, and a hanging ring 308 is provided in the middle of the mounting bracket 307. The hanging ring 308 can be used to connect with the traction component of the ship to move the device to the working position.

[0019] In use, the device is transported to the target water area by boat, with the boat's power supply powering the pumps inside the device. Using the hanging rings 308 on the mounting bracket 307 fixed to the side of the mounting plate 3, it is connected to the boat's towing assembly via ropes, allowing the boat to tow or hoist the device to the predetermined submerged plant transplant source area (for extraction) or target planting area (for transplanting). Depending on the actual water depth of the work area, the positioning bolts 105 connecting the mounting steel pipe 103 and the adjusting steel pipe 201 are loosened, and the adjusting steel pipe 201 (along with the transplanting container 2 below it) is slid along the axial direction of the mounting steel pipe 103, thereby adjusting the distance between the hollow cabin 1 and the transplanting container 2. Once the distance is adjusted to suit the water depth, the top of the adjusting steel pipe 201... Align the second positioning hole 202 with the corresponding positioning hole 104 on the surface of the installation steel pipe 103, reinsert and tighten the positioning bolt 105 to securely lock the position of the adjusting steel pipe 201 and the installation steel pipe 103; start the water pump inside the hollow chamber 1, and the water pump draws external water into the internal cavity of the hollow chamber 1 through the water inlet pipe 101. As the amount of water entering the hollow chamber 1 increases, the overall weight of the device increases, the buoyancy decreases, and the device begins to sink. The device continues to sink until the transplant container 2 and the installation frame 203 at the bottom contact the bottom mud. The serrated titanium alloy blade of the cutting plate 205 is ready to cut into the bottom mud; the operator rotates the wheel 302 fixed at the top of the rotating shaft 301, and the wheel 302 drives the rotating shaft 301 to rotate. The rotation of the screw drives the bevel gear 203 fixed at its bottom to rotate. The bevel gear 203 meshes with the bevel gear 2011 fixed at the end of the mounting shaft 2010, transmitting the rotational motion to the mounting shaft 2010. The mounting shaft 2010 drives the bidirectional lead screw 209 to rotate. The two ends of the bidirectional lead screw 209 are threadedly connected to the connecting brackets 207 fixed to the outer sides of the top of the two cutting plates 205. The rotation of the bidirectional lead screw 209 drives the two connecting brackets 207 (and the cutting plates 205 fixed to them) to move synchronously in opposite directions (closed direction). The serrated titanium alloy blades of the two cutting plates 205 converge towards the center synchronously, cutting into the bottom mud and cutting the target submerged plant and its core root system inside the cutting plate 205. The mud is completely cut, enclosed, and extracted; after the cutting plate 205 is closed in place, the two locking nuts 306 on the locking screw 305 (the locking nuts 306 are located on both sides of the through hole of the locking frame 304) can be tightened to lock the rotating shaft 301 and prevent the rotating wheel 302 from rotating accidentally and causing the cutting plate 205 to open accidentally; the drainage pump inside the hollow chamber 1 is started, and the drainage pump discharges the water inside the hollow chamber 1 to the external environment through the drainage pipe 102. As the amount of water inside the hollow chamber 1 decreases, the overall weight of the device decreases and the buoyancy increases. The device (along with the complete "plant-substrate block" extracted inside it) begins to float and detaches from the bottom of the water; after the device floats, it is towed or hoisted to the target planting area by a boat through the hanging ring 308.The water pump is started to inject water into the hollow chamber 1, causing the device carrying the "plant-substrate block" to sink again to the bottom of the target planting point. If the rotating shaft 301 was previously locked, the locking nut 306 is loosened first, and the rotating wheel 302 is rotated in the opposite direction, driving the two cutting plates 205 to move synchronously in opposite directions (opening direction). The two cutting plates 205 open synchronously to both sides, smoothly releasing the complete "plant-substrate block" and placing it at the planting position on the target bottom of the water. The drainage pump is started to drain the water from the hollow chamber 1, causing the entire device to float. After the device floats, it is towed by a boat through the hanging ring 308 to remove it from the transplanting point, completing one transplanting operation.
