Description

Technical Field

[0001] The utility model belongs to the technical field of deep-sea mineral resource development, in particular to a cover body for inhibiting the diffusion of plume-like flow of seabed sediments. Background Art

[0002] At present, the crawler mining vehicles used in offshore polymetallic nodule mining experiments at home and abroad all use hydraulic motors to drive the crawlers to operate, and the crawler teeth shear the bottom of the seabed sediments to generate shear force, providing the traction required for steady-state driving. Because the particle size of the seabed sediments is extremely small, after being sheared and disturbed by the grousers and moved to the tail of the mining vehicle by the grousers, and then continuing to move upward with the grousers to leave the seabed, a mud-water mixed plume will be generated. The plume will spread under the action of the seabed current, which will affect the organisms in the surrounding water bodies; and the sediment particles in the plume will gradually settle during the diffusion process, which will affect the surface organisms on the seabed.

[0003] As shown in the patent application number 202323156103.0, entitled A Low-Disturbance Seabed Crawler Driving Platform, in order to avoid causing a large disturbance to the seabed environment, existing crawler mining vehicles usually have a cover covering the crawler to suppress the diffusion of sediment plumes. The cover is fixed to the crawler mining vehicle and goes into the water with the crawler mining vehicle. When entering the water, the air in the cover cannot be discharged. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the relevant technical solutions. Obviously, the described embodiments are only part of the embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 As shown, the cover body for suppressing the diffusion of seabed sediment plume disclosed in this embodiment includes a cover body main frame 1, a cover body side frame 2, a cover plate 3 and a connecting seat 4.

[0021] A cover body side frame 2 is arranged on both the front and rear sides of the cover body main frame 1, eighteen cover plates are evenly arranged on the top of the cover body main frame, and a connecting seat 4 connected to the crawler track is arranged inside the cover body main frame.

[0022] The cover body main frame 1 is a U-shaped frame composed of multiple steel plates, and vertical connecting plates are arranged on the edges of both sides thereof. The connecting plates are welded to the cover body main frame through multiple triangular connecting plates.

[0023] The cover body side frame 2 is composed of a plurality of steel plates, one end of which is U-shaped and the other end is closed. A connecting plate is arranged at the edge of the U-shaped side of the cover body side frame.

[0024] like Figure 2 As shown, the U-shaped edges of the two cover side frames 2 are butted against the cover main frame 1, and the connecting plates of the two are tightly attached. The tightly attached connecting plates are fastened and connected by multiple sets of bolts to connect the cover side frames and the cover main frame into one.

[0025] The top of the cover main frame 1 is evenly provided with 18 rectangular openings, and 18 cover plates 3 are connected to each opening. A spring hinge 31 is arranged at the edge of the rectangular opening, one end of the spring hinge is fixed to the edge of the rectangular opening, and the other end is connected to the cover plate.

[0026] When the cover body goes into the water with the mining vehicle, the air in the cover body can push the cover plate open and automatically discharge upward. When the air in the cover body is completely discharged, the cover plate can be closed again under the elastic force of the spring hinge.

[0027] like Figure 3 As shown, a pair of connecting seats 4 are provided on both sides of the inner cavity of the cover main frame 1. The connecting seat comprises a U-shaped steel and rectangular plates on both sides thereof. One end of the connecting seat is fixed to the cover main frame through a rectangular plate and bolts, and the other end can be connected and fixed to the crawler of the crawler mining car.

[0028] When the cover is installed on the crawler of a crawler mining vehicle, the cover main frame is first fixed to the crawler frame of the crawler through the connecting seat, and then the cover side frames are installed on both sides of the cover main frame.

[0029] The advantages of using this mask are:

[0030] 1. A cover is set to cover the track to control the initial height of the plume generation and external diffusion, thereby reducing the diffusion range under the action of the seabed current.

[0031] 2. The cover body is provided with a plurality of openings for closing with cover plates and spring hinges. When the mining vehicle enters the water, the air and seawater trapped in the cover body can push the cover plates open and be automatically discharged upwards; when the mining vehicle stops lowering, the cover plates can be closed again under the elastic force of the spring hinges, ensuring that the cover body can suppress the diffusion of sediment plumes formed by the track disturbance when the mining vehicle is driving on the seabed.

[0032] 3. The cover body is split, which is easy to install and use.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
