Description

Technical Field

[0001] The present invention belongs to the technical field of seabed mineral resource exploitation, and particularly relates to an environment-friendly deep-sea mineral collection device. Background Art

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope protected by the present application.

[0032] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides an environmentally friendly deep - sea mineral collection device. The environmentally friendly deep - sea mineral collection device includes a mining head 1, a protective cover 2 located outside the mining head 1, and a mining head support frame 11 disposed opposite to the mining head 1. The mining head 1 is connected to a rotary drive motor 8 through a coupling 10, and the rotary drive motor 8 is fixed on the mining head support frame 11.

[0033] On one side of the mining head support frame 11, a double - row cylindrical guide rail 17 is installed. The double - row cylindrical guide rail 17 is equipped with a moving slider 12. An axial position adjustment hydraulic cylinder 13 is installed in the axial position of the moving slider 12, and a radial position adjustment hydraulic cylinder 14 is installed in the radial position of the moving slider 12; the protective cover 2 is connected to the radial position adjustment hydraulic cylinder 14 through a fixed bracket 15 to realize the relative position movement in the radial direction between the environmentally friendly deep - sea mineral collection device and the mining head 1, and adjust the relative position between the mining head 1 and the protective cover 2 according to the output of the particles of the minerals collected by the mining head 1.

[0034] As Figure 1 、Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in FIGS. Figure 2 to Figure 10 , a sponge pad 16 is fixedly installed inside the protective cover 2. The sponge pad 16 is used to weaken the collision of splashed debris during the cutting process of the mining head. After the debris splashes onto the sponge pad, it can roll down along the inner wall under the action of gravity. The protective cover 2 is connected to a strip-shaped fixing plate 5 and a jet pipe 7. The strip-shaped fixing plate 5 is connected to a suction pipe 6. The jet pipe 7 is used to wash the deep-sea mineral debris to the inlet end of the suction pipe 6. The jet pipe 7 can use the tail water to be discharged during mining, so that seawater is recycled, reducing the pollution of the tail water to the environment, and thus reflecting the realization of environmentally friendly collection.

[0035] Upper cleaning brushes 3 and lower cleaning brushes 4 are respectively installed on both sides of the protective cover 2. The hemispherical surface of the mining head 1 is provided with multiple rows of cutting tooth assemblies 21. The cutting tooth assemblies 21 are used to crush the deep-sea mineral metal crust layer. The connecting shaft of the mining head 1 is connected to the coupling 10 through a rolling bearing 9. The suction pipe 6 is a multi-branch pipeline structure to realize the collection of debris at different falling positions inside the mining head 1.

[0036] In this embodiment, the upper cleaning brushes 3 and the lower cleaning brushes 4 are used to sweep the rock debris adhered to the cutting tooth assemblies 21; in addition, the upper cleaning brushes 3 and the protective cover 2 form an approximately airtight space, which can achieve efficient collection while reducing the diffusion of the plume.

Figure 17 is a schematic structural diagram of the sponge pad 16.

[0038] As described above, an environment-friendly deep-sea mineral collection device in this embodiment is mainly to solve the problem of low mineral collection efficiency. The environment-friendly deep-sea mineral collection device mainly includes a mining head 1, on which multiple rows of pick assemblies 21 are installed. The mining head 1 is connected to a rotary drive motor 8 through a coupling 10. The rotary drive motor 8 is fixed to the mining head support frame 11 by screws. One side of the mining head support frame 11 is equipped with a double-row cylindrical guide rail 17, and a moving slider 12 is assembled on the cylindrical guide rail 17. The movement of the moving slider 12 is driven by the telescopic movement of an axial position adjustment hydraulic cylinder 13, pushing it to move circumferentially along the axial center line. At the same time, a radial position adjustment hydraulic cylinder 14 is connected to the moving slider 12 by screws. Behind the deep-sea mining cutting direction, a collection structure inside the protective cover 2 is arranged. The protective cover 2 is connected to the radial position adjustment hydraulic cylinder 14 by a fixed bracket 15 through screws. The telescopic adjustment of the radial position adjustment hydraulic cylinder 14 can achieve the relative position between the collection device and the mining head in the radial direction, so that the relative position between the mining head 1 and the protective cover 2 can be adjusted according to the yield of mineral particles collected by the mining head 1. A sponge pad 16 is fixed inside the protective cover 2. The main function of the sponge pad 16 is that when the mining head is cutting, the spattered debris hitting the sponge pad can weaken its collision. After hitting the sponge pad, it can roll down along the inner wall under the action of gravity. Further, it is washed to the inlet end of the suction pipe 6 through a jet pipe 7 on one side. The suction pipe 6 is connected to the protective cover 2 through a strip-shaped fixing plate 5. At the same time, an upper cleaning brush 3 and a lower cleaning brush 4 are respectively installed on both sides of the protective cover 2. The main function of the cleaning brush is, on the one hand, considering that during the deep-sea mineral excavation process, debris adheres to the pick assembly 21. Through the brush, the attached mineral debris can be swept off. On the other hand, the tight and dense brush structure can better fit on the mining head, so as to better form a closed space and achieve an environment-friendly collection of debris.

[0039] During the deep-sea mining process, first, the axial position of the protective cover is adjusted through the axial position adjustment hydraulic cylinder; when the specified depth is reached, the radial position adjustment hydraulic cylinder is used to adjust the radial position of the protective cover; during the excavation process, the radial position adjustment hydraulic cylinder is also used to finely adjust the position of the protective cover in real time according to the yield of the excavated minerals, so as to achieve efficient and environment-friendly collection of ore particles.

[0040] In summary, although the present invention has been disclosed above with preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is subject to the scope defined by the claims.
