Description

Technical Field

[0001] The present invention relates to the technical field of marine ecological environment restoration, and particularly to a device and a method for environmental restoration after deep-sea mining. Background Art

[0002] Submarine mining is the work of extracting submarine mineral resources, mainly collecting the submarine surface sediments with relatively shallow water depths, such as placer deposits, apatite, and polymetallic nodules, etc. At present, the key technologies for the exploitation of submarine resources mainly have two aspects: one is the excavation of submarine ore bodies; the other is the underwater lifting and transportation of ores. And the core of them is the submarine mining equipment and ore lifting equipment with relatively high technical difficulties. There are three recognized most promising submarine mining devices in the world: bucket-chain mining device, pneumatic mining device, and water pump mining device. Deep-sea mining may cause great damage to marine organisms, especially benthic organisms and habitats, so it is necessary to repair the deep-sea environment after deep-sea mining.

[0003] Deep-sea mining will disturb the fine sediments on the seabed, resulting in the formation of suspended particle plumes around the mining area. These suspended particles will disperse hundreds of kilometers away and take a long time to redeposit on the seabed. These suspended particles will cause animals to suffocate, harm filter-feeding animals, hinder visual communication between animals, and have an adverse impact on the ecosystem and species with ecological and commercial significance. Summary of the Invention

[0006] In a preferred embodiment, a fixing seat is fixedly connected to one side of one of the first support rods, and a universal motor is fixedly connected to one side of the fixing seat. The driving end of the universal motor is connected to one side of the winding disc through a coupling. Two second support rods are fixedly connected to one side of the U-shaped bracket.

One side of the repair ship body is bolted to a support plate. An installation circular hole is formed on one side of the support plate. A hollow limiting tube is fixedly connected inside the installation circular hole.

[0007] In a preferred embodiment, a purification box is bolted to one side of the connecting plate, and a partition board is fixedly connected to one side of the purification box.

The same filtering cylinder is fixedly connected to one side of the two hollow suction pipes. Filtering ports are equidistantly arranged on the outside of the filtering cylinder. A linkage gear is fixedly connected to the outside of one of the hollow suction pipes.

[0008] In a preferred embodiment, a circular hole IV is formed on one side of the purification box, and a rotating shaft is connected inside the circular hole IV through a bearing. A semi-circular gear is fixedly connected to the outside of the rotating shaft. The tooth block end of the semi-circular gear meshes with the linkage gear.

[0010] In a preferred embodiment, two circular holes VI are formed on both the purification box and the partition board, and the same water inlet pipe is fixedly connected inside the two circular holes VI on the same side. The same hollow installation frame is fixedly connected to one side of the two water inlet pipes. Water inlet grooves are equidistantly arranged on one side of the hollow installation frame. A sliding groove is formed on one side of the hollow installation frame. A water stop plate is slidably connected inside the sliding groove. An installation plate is fixedly connected to one side of the purification box. Two first electric telescopic rods are fixedly connected to one side of the installation plate. The driving end of the first electric telescopic rod is fixed to one side of the water stop plate.

[0011] By setting up a repair component, when collecting suspended particles generated during mining, the purification box is driven by the repair ship body to move to the repair point. Then, the general motor is started to drive the winding disc, so that the lifting rope drives the purification box to descend to the suspended particle punctuation point. Then, the pump body is started, and the plume is sucked through the hollow mounting frame located on one side of the purification box. The sucked plume is transported to the baffle through the water inlet pipe. At this time, the filter cylinder located in the baffle filters the suspended particles in the plume. The suspended particles fall due to gravity. Then, the pump body discharges the filtered plume back into the ocean. During the filtration process of the filter cylinder, the driving motor is started to drive the semi-circular gear to rotate, so that the semi-circular gear drives the linkage gear to intermittently drive the hollow suction pipe to rotate, so that the filter cylinder rotates intermittently, avoiding the filter surface of the filter cylinder always facing the water inlet end to generate adherents. At the same time, the cleaning brush plate located on one side of the filter cylinder cleans the outer wall of the filter cylinder through the extrusion of the compression spring. Through the repair component, the particulate matter in the plume at different depths in the seabed can be collected, avoiding the suspension particles from causing animal asphyxiation, harming filter-feeding animals, hindering the visual communication between animals, and having an adverse impact on the ecosystem and species with ecological and commercial significance.

[0012] In a preferred embodiment, a collection component is provided on one side of the purification box. The collection component includes a partition. A material discharge port is opened on one side of the partition. Circular holes VII are opened on both sides of the material discharge port. The inner parts of two opposite circular holes VII are connected by bearings to an adjustment round shaft. The outer parts of the two adjustment round shafts are fixedly connected with opening and closing collection plates. One side of the partition is bolted to a collection frame. A material discharge hole is opened on one side of the collection frame. A material discharge pipe is fixedly connected to the inner part of the material discharge hole. Filter holes are equidistantly opened on one side of the material discharge pipe. An electronic valve is flange-connected to the outside of the material discharge pipe.

[0013] In a preferred embodiment, a guiding track is fixedly connected to one side of the purification box. A push-pull toothed plate is slidably connected to the inside of the guiding track.

An observation port is opened on one side of the collection frame. A transparent observation window is fixedly connected to the inside of the observation port.

[0014] When filtering suspended particles by setting up a collection component, at this time, the suspended particles fall to one side of the partition by their own weight. When there are too many particulate matters above the partition, by starting the second electric telescopic rod, the second electric telescopic rod drives the push-pull tooth plate to make the rotating gear rotate, so that the rotating gear drives the adjusting circular shaft to make the opening and closing collection plate open, so that the particulate matters above the partition fall into the collection box. Then, the opening and closing collection plate is closed, and then by starting the electronic valve, the seawater is discharged through the discharge pipe, so as to retain the particulate matters in the collection box.

[0015] In a preferred solution, telescopic springs are fixedly connected to the multiple sides of the hollow limiting tube at equal intervals, and mounting frames are fixedly connected to the outside of the multiple telescopic springs on the same side. Circular holes eight are evenly opened on both sides of each mounting frame, and ball bearings are connected inside the two opposite circular holes eight through bearings.

[0016] By setting up telescopic springs, mounting frames and ball bearings, when the lifting rope lifts and lowers the purification box, at this time, the lifting rope moves in the hollow limiting tube. The telescopic springs in the hollow limiting tube make the ball bearings on the mounting frame abut against the lifting rope through their elasticity. The contact area between the lifting rope and the ball bearings is small, so as to reduce the friction with the lifting rope and extend its service life.

[0017] A usage method of a device for deep-sea mining environmental restoration, using a device for deep-sea mining environmental restoration as described above, includes the following steps:

[0018] Step 1: When collecting the suspended particles generated during mining, drive the purification box to move to the restoration point by the repair ship body, and then start the general motor to drive the winding disc so that the lifting rope drives the purification box to descend to the suspended particle marking point;

[0019] Step 2: Then start the pump body, suck the plume through the hollow mounting frame on one side of the purification box, and transport the sucked plume to the baffle through the water inlet pipe. At this time, the filter cylinder in the baffle filters the suspended particles in the plume. The suspended particles fall by their weight, and then the pump body discharges the filtered plume back into the ocean interior;

[0020] Step 3: During the filtering process of the filter cylinder, start the driving motor to drive the semi-circular gear to rotate, so that the semi-circular gear drives the linkage gear to intermittently drive the hollow suction pipe to rotate, so that the filter cylinder rotates intermittently, avoiding the filter surface of the filter cylinder always facing the water inlet end to generate adhesion substances, and at the same time making the cleaning brush plate on one side of the filter cylinder clean the outer wall of the filter cylinder through the extrusion of the compression spring.

[0021] As can be seen from the above, a device for deep - sea mining post - environmental restoration provided by the present invention has the beneficial effect of being able to collect particulate matter in plumes at different depths on the seabed, avoiding suspension particles from causing animal asphyxiation, harming filter - feeding animals, hindering visual communication between animals, and having an adverse impact on the ecosystem and species of ecological and commercial significance.

[0050] Working principle: When collecting suspended particles generated during mining, the repair ship body 1 drives the purification box 201 to move to the repair point, and then starts the general motor 222 to drive the winding disk 221, so that the lifting rope 227 drives the purification box 201 to descend to the suspended particle punctuation point. When the lifting rope 227 lifts and lowers the purification box 201, at this time, the lifting rope 227 moves in the hollow limiting tube 228. The telescopic spring 4 located in the hollow limiting tube 228 makes the ball 6 on the mounting frame 5 abut against the lifting rope 227 through its telescopic property. The contact area between the lifting rope 227 and the ball 6 is small, so as to reduce the friction on the lifting rope 227 and extend its service life. Then start the pump body 230, and suck the plume through the hollow mounting frame 215 on one side of the purification box 201, and transport the sucked plume to the baffle 202 through the water inlet pipe 214. At this time, the filter cylinder 208 located in the baffle 202 filters the suspended particles in the plume. The suspended particles fall due to their weight. Then the pump body 230 discharges the filtered plume back into the ocean. During the filtering process of the filter cylinder 208, start the drive motor 204 to drive the semi-circular gear 206 to rotate, so that the semi-circular gear 206 drives the linkage gear 209 to intermittently drive the hollow suction pipe 207 to rotate, so that the filter cylinder 208 rotates intermittently, avoiding the filter surface of the filter cylinder 208 always facing the water inlet end to generate adherents. At the same time, the cleaning brush plate 213 located on one side of the filter cylinder 208 cleans the outer wall of the filter cylinder 208 through the extrusion of the compression spring 212. When filtering the suspended particles, at this time, the suspended particles fall to one side of the partition plate 301 due to their own weight. At this time, when there are too many particles above the partition plate 301, start the electric telescopic rod two 304, so that the electric telescopic rod two 304 drives the push-pull tooth plate 305 to make the rotating gear 306 rotate, so that the rotating gear 306 drives the adjusting round shaft 311 to make the opening and closing collecting plate 312 open, so that the particles above the partition plate 301 fall into the collecting frame 302. Then close the opening and closing collecting plate 312, and then start the electronic valve 308 to discharge the seawater through the blanking pipe 309, so as to retain the particles in the collecting frame 302.
