Embodiment Construction
[0026] In order to further understand the present invention, preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0027] see Figure 1-2 , a composite skid-type seabed mine car traveling device, including a mine car main body 1, a propulsion steering device 2, a running device 3, and a buoyancy control device 4, and the propulsion steering device 2 is located at the tail of the mine car main body 1.
[0028] Wherein, the propulsion steering device 2 includes a propeller propeller 201 , a fairing 202 , and a deflector 203 . The fairing 202 is wrapped around the propeller propeller 201 to gather water flow and reduce kinetic energy consumption. The deflector 203 is arranged on the rear edge of the fairing 202, which can be moved left and right to realize steering, and can change the direction of propeller water outlet, thereby changing the forward direction. direction. There are two propeller propelle...

Abstract
The invention discloses a composite sled type seabed mine car traveling device, which comprises a main body of the mine car, a propulsion steering device, a traveling device and a buoyancy control device. The propulsion steering device includes a propeller propeller, a fairing, and a deflector. Skid board, flexible skid board, rigid skid board is fixedly connected to the lower part of the main body of the mine car, flexible skid board is fixedly connected under the rigid skid board, flexible skid board includes an outer protective layer, water bag, air bag; the outer protective layer is provided with multiple An independent water bag, the upper part of the water bag is closely connected with the skid board, and an air bag is installed inside the water bag; the buoyancy control device includes a high-pressure water pump, a water pipeline, a water distribution tank, a water filling valve, a drain valve, a high-pressure air tank, an air pipeline, an inflation valve, As for the exhaust valve, each water bag is provided with a water filling valve and a drain valve, and the air bag is provided with an inflation valve and an exhaust valve. The invention can make the seabed mine car suitable for different working modes such as placement, walking, self-rescue from trap, recovery and the like.
Description
technical field [0001] The invention relates to the field of marine mineral resource mining equipment, in particular to a composite skid-type seabed mine vehicle traveling device. Background technique [0002] Polymetallic nodules have great mining value and are mainly distributed in the surface layer of abyssal plain sediments. This kind of sediment is generally very soft, and when the mine car walks on it, it is very easy to produce a large subsidence. And the water content is high, the friction angle is almost 0, and the friction between the vehicle and the vehicle is very small, and the ordinary wheeled walking device is very easy to slip. [0003] At present, the seabed mining vehicles mainly include self-propelled crawler type and Archimedes screw propulsion type, etc. Among them, the crawler type is the mainstream type, which mainly relies on the crawler teeth to insert into the sedimentary soil for shearing, and utilizes the shearing force of the crawler teeth on th...
