Description

Technical Field

[0001] This invention relates to the field of aquatic sediment remediation technology, specifically to an in-situ sediment remediation device. Background Technology

[0002] Bottom sediment is a muddy substance composed of clay, silt, sand, organic matter, or various minerals deposited at the bottom of a water body. For aquatic waters, bottom sediment mainly originates from soil erosion, the decomposition of plant and animal organisms, and particulate matter contained in sewage discharged into the water. As the main reservoir of pollutants in rivers, lakes, and other aquatic waters, bottom sediment can not only directly reflect the pollution history of the water body, but also, under certain conditions, pollutants in the bottom sediment can release various pollutants into the overlying water body through desorption, dissolution, and biological decomposition.

[0003] Currently, in-situ sediment remediation technology is commonly used for sediment remediation. This technology involves controlling harmful sediment pollution in rivers and lakes by applying physicochemical methods or biodegradation pathways in situ. To deliver remediation materials into the sediment, corresponding in-situ sediment remediation devices need to be developed. Summary of the Invention

[0039] The reference numerals in the accompanying drawings include: carrier 1, feeding mechanism 2, storage tank 201, feeding pipe 202, first switch assembly 203, vent pipe 204, second switch assembly 205, feeding mechanism 3, feeding rod 301, feeding sleeve 302, protective sleeve 303, vertical nozzle 304, vertical injection nozzle 305, spherical head 306, insertion head 307, drive mechanism 4, first lifting assembly 401, first motor 402, mounting base 403, second motor 404, lead screw 405, movable seat 406, guard plate 5, mounting frame 6, top plate 601, side plate 602, bottom plate 603, guide rod 604.

[0040] The following detailed description illustrates the specific implementation method:

[0041] As attached Figure 1 To be continued Figure 7 As shown, in an exemplary embodiment of this application, the in-situ sediment remediation device includes:

[0042] Carrier 1, used for floating on water;

[0043] The feeding mechanism 2, installed on the carrier 1, is used to supply repair materials;

[0044] The feeding mechanism 3 is connected to the output of the feeding mechanism 2 and is used to transport the repair material to the bottom mud. The feeding mechanism 3 includes a feeding rod 301 and a feeding sleeve 302. The feeding rod 301 extends into the feeding sleeve 302 to form a conveying channel for transporting the repair material.

[0045] The drive mechanism 4 is installed on the carrier 1. The output end of the drive mechanism 4 is connected to the feeding mechanism 3 and is used to drive the feeding mechanism 3 to extend into the bottom mud to transport the repair material.

[0046] In this embodiment, the carrier 1 allows the in-situ sediment remediation device to float on the water surface, facilitating in-situ remediation of the sediment. The feeding mechanism 2 holds the remediation material and supplies it to the conveying mechanism 3. After the remediation material is supplied to the conveying mechanism 3, the drive mechanism 4 activates the conveying mechanism 3 to transport the remediation material into the sediment for remediation.

[0047] For example, carrier 1 can be a ship.

[0048] For example, the drive mechanism 4 is used to drive the feeding rod 301 to rotate and convey the repair material, and at the same time drive the feeding rod 301 and the feeding sleeve 302 to perform plunger movement to squeeze the repair material into the mud.

[0049] In an exemplary embodiment, a mounting frame 6 is provided on the carrier 1, and the feeding mechanism 2 and the driving mechanism 4 are respectively mounted on the mounting frame 6.

[0050] In this embodiment, the mounting frame 6 is set up to install the feeding mechanism 2, the driving mechanism 4, etc.

[0051] For example, protective plates 5 are provided on opposite sides of the mounting frame 6, and the protective plates 5 are connected to the carrier 1 to increase the stability of the mounting frame 6.

[0052] For example, the mounting frame 6 includes a base plate 603, a top plate 601, and side plates 602 disposed on opposite sides, with the guard plate 5 connected to the side plates 602.

[0053] For example, the carrier 1 is provided with a square through hole to facilitate the installation and operation of the feeding mechanism. The square through hole is located at the center of gravity of the carrier 1 to reduce the possibility of tipping over and increase water balance. A sealing structure can be added between the edge of the square through hole and the feeding mechanism to increase floating stability.

[0054] In one exemplary embodiment, the drive mechanism 4 includes:

[0055] The first lifting component 401 is mounted on the mounting frame 6;

[0056] A rotary drive assembly is installed at the output end of the first lifting assembly 401, and the output end of the rotary drive assembly is connected to the feeding rod 301.

[0057] It should be noted that the first lifting component 401 is used to drive the rotary drive component to lift and lower, thereby driving the feeding rod 301 to lift and lower. The rotary drive component is used to drive the feeding rod 301 to rotate, so as to realize the conveying of repair materials in the conveying channel.

[0058] For example, the first lifting assembly 401 includes a reversible servo electric push rod, the top plate 601 of the mounting frame 6 has a square opening for the reversible servo electric push rod to extend out, and the bottom plate 603 of the mounting frame 6 has an inlet and outlet for the feeding mechanism 3 to extend out.

[0059] In one exemplary embodiment, the mounting frame 6 is provided with a guide rod 604 for guiding the lifting of the first lifting assembly 401, and the rotation drive assembly includes:

[0060] Mounting base 403 is mounted on guide rod 604 and can move along the length of guide rod 604. Mounting base 403 is connected to the output end of first lifting assembly 401.

[0061] The first motor 402 includes a stator and a rotor. The stator is connected to the mounting base 403, and the rotor is connected to the feed rod 301.

[0062] It should be noted that, in order to serve a positioning function and prevent the first motor 402 from rotating when it is working, a mounting base 403 is provided and mounted on the guide rod 604. Since the mounting base 403 needs to move up and down under the drive of the first lifting assembly 401, the mounting base 403 needs to be able to slide along the guide rod 604.

[0063] In this embodiment, the guide rod 604 also serves to guide the movement of the feeding mechanism 3.

[0064] For example, at least two guide rods 604 are provided, both of which pass through the mounting base 403.

[0065] For example, four guide rods 604 are provided, and the four guide rods 604 are distributed in a quadrilateral shape.

[0066] In one exemplary embodiment, the drive mechanism 4 further includes a second lifting component, the output of which is connected to the feeding sleeve 302.

[0067] In this embodiment, the second lifting component is used to drive the feeding sleeve 302 to move, so that the feeding sleeve 302 extends into the bottom mud to the position that needs to be repaired.

[0068] In one exemplary embodiment, the second lifting mechanism includes:

[0069] The movable seat 406 is mounted on the guide rod 604 and can move along the length of the guide rod 604;

[0070] The second motor 404 is mounted on the mounting frame 6;

[0071] The lead screw 405 has one end connected to the output of the second motor 404, and the other end of the lead screw 405 passes through the movable seat 406 and can be rotatably mounted on the mounting frame 6 along its own axis. The lead screw 405 and the movable seat 406 are threaded together.

[0072] The feeding sleeve 302 is installed on the movable seat 406.

[0073] In this embodiment, the feeding sleeve 302 is mounted on the movable seat 406 to move with the movable seat 406. The movable seat 406 is mounted on the guide rod 604, enabling the movable seat 406 to move more stably. The second motor 404 is provided to drive the lead screw 405 to rotate. The lead screw 405 is threadedly engaged with the movable seat 406, so the movable seat 406 will move up and down during the rotation of the lead screw 405.

[0074] For example, the second motor 404 is mounted on the top plate 601 of the mounting frame 6, and the bottom end of the lead screw 405 is connected to the bottom plate 603 of the mounting frame 6. The guide rod 604 connects the top plate 601 and the bottom plate 603 of the mounting frame 6.

[0075] It should also be noted that the first lifting component 401 and the second lifting component work together to create a plunger-like structure between the feeding rod 301 and the feeding sleeve 302, thereby delivering the repair material.

[0076] In one exemplary embodiment, the feeding mechanism 3 includes:

[0077] Storage hopper 201 is installed on carrier 1;

[0078] The feeding pipe 202 is connected to the storage tank 201, and a first switch assembly 203 for controlling the on / off of the feeding pipe 202 is provided on the feeding pipe 202.

[0079] A vent pipe 204 is connected to a feeding pipe 202, and the vent pipe 204 is located at the end of the first switch assembly 203 away from the storage tank 201. A second switch assembly 205 for controlling the opening and closing of the vent pipe 204 is provided on the vent pipe 204.

[0080] It should be noted that the storage hopper 201 is designed to store repair materials. The feeding pipe 202 is designed to transport the repair materials from the storage hopper 201 to the feeding sleeve 302. The vent pipe 204 is designed to connect to an air source and introduce gas into the feeding sleeve 302. The first switch assembly 203 is designed to control the delivery of repair materials. The second switch assembly 205 is designed to control the delivery of gas.

[0081] For example, a blower is connected to the vent pipe 204 to introduce air to meet the repair requirements.

[0082] In an exemplary embodiment, the portion of the feeding rod 301 that extends into the feeding sleeve 302 is provided with a threaded groove, which cooperates with the inner wall of the feeding sleeve 302 to form a conveying channel.

[0083] In this embodiment, the threaded groove is provided so that the repair material can be conveyed to the bottom mud along the threaded groove during the rotation of the feed rod 301.

[0084] For example, the lower half of the feed rod 301 is provided with threaded protrusions, and threaded grooves are formed between the threaded protrusions. The upper half of the feed rod 301 does not have threaded protrusions, so when it is engaged with the feed sleeve 302, an annular gap is formed to facilitate the entry of repair material.

[0085] In an exemplary embodiment, a tapered head is provided at one end of the feed rod 301 near the bottom mud, and a guide groove is provided on the tapered head for guiding the repair material from the conveying channel to the tip of the tapered head.

[0086] In this embodiment, the guide groove is provided to facilitate the output of repair materials.

[0087] In an exemplary embodiment, a vertical nozzle 305 is provided at one end of the feeding sleeve 302 near the bottom mud, and a vertical spray nozzle 304 is provided inside the feeding sleeve 302 corresponding to the vertical nozzle 305. The vertical spray nozzle 304 is provided with a groove that mates with a conical head.

[0088] During use, the repair material, under its own gravity, rotates with the feed rod 301 and enters the guide groove. The guide groove then leads into the vertical nozzle 304, from which the material is sprayed out from the vertical nozzle 305. The vertical nozzle 304 has a groove that matches the conical head, ensuring that the conical head on the feed rod 301 conforms to the groove after descending, reducing dosage errors caused by incomplete entry of the repair material into the bottom mud.

[0089] For example, the groove is a conical groove to better match the conical head.

[0090] For example, both the feeding sleeve 302 and the vertical nozzle 305 are provided with protective sleeves 303. The protective sleeves 303 are hollow concentric cylinders with open sides to facilitate operations such as replacement of the protective sleeves 303. The provision of protective sleeves 303 reduces the possibility of corrosion on the surface of the feeding sleeve 302 and the vertical nozzle 305.

[0091] The specific implementation process is as follows: After the carrier 1 reaches the working position, the second lifting component activates, causing the feeding sleeve 302 to descend to a specified depth and then stop lifting. The feeding mechanism 2 outputs repair material into the feeding sleeve 302. The rotation drive component activates, causing the feeding rod 301 to rotate, so that the repair material is transported along the conveying channel to the vertical nozzle 304 and vertical injection nozzle 305 under its own gravity. The repair material is extruded through the coordinated action of the first lifting component 401 and the second lifting component to achieve repair. After the required amount of repair material is delivered, the feeding mechanism 2 stops feeding, and the first lifting component 401 drives the feeding sleeve 302 to reset upwards. At the same time, the first lifting component 401 drives the feeding rod 301 to reset upwards.

[0092] It is also worth noting that the rotation of the feed rod 301 also serves to prevent blockage.

[0093] For example, both the first switch assembly 203 and the second switch assembly 205 are toggle switches to adjust the feeding amount and air volume. This can accurately achieve the target without waste, and ensure that the air volume is sufficient to prevent the repair material from clogging the feeding mechanism 3 and from stirring up the bottom mud to cause secondary pollution.

[0094] In one exemplary embodiment, to achieve better repair, the vertical nozzle 305 and the vertical spray nozzle 304 may also be configured with the following structure:

[0095] A spherical head 306 is provided at the bottom of the feeding sleeve 302. An insertion head 307 is hinged to the outside of the spherical head 306. The insertion head 307 and the spherical head 306 are spherically hinged. A groove matching the conical head on the feeding rod 301 is provided inside the spherical head 306 to act as a vertical nozzle 304. A vertical nozzle 305 is provided at the outlet of the groove corresponding to the insertion head 307 to output the repair material. The insertion head 307 can be made of a heavier material (such as metal) to overcome the buoyancy of water and fall freely into the bottom mud to be repaired. The insertion head 307 and the spherical head 306 or the feeding sleeve 302 can be elastically sealed. The elastic seal can be made by means of an elastic sealing sleeve to ensure that the repair material exits from the outlet on the insertion head 307.

[0096] It is worth noting that in some scenarios where remediation materials need to be injected into the bottom sediment, the carrier 1 floats on the water surface and will drift with the water flow. The design of the insert head 307 and the spherical head 306 allows for a certain amount of movement between the feeding sleeve 302 and the insert head 307, thereby reducing the possibility of secondary pollution caused by disturbance of the bottom sediment.
