Description

Technical Field

[0001] The present invention relates to the technical field of marine mining equipment, and in particular to a deep-sea mining vehicle with viscosity reduction and anti-skid functions. Background Art

[0002] A deep-sea mining vehicle is a deep-sea mining operation equipment that travels at a depth of 5,000 to 6,000 meters. Because the soft sediments in the deep sea are relatively soft and easily adhere to the grousers of the deep-sea mining vehicle's tracks, as the deep-sea mining vehicle travels on the seabed, the soil adhesion between the grousers will become more and more serious, and eventually all the grousers will be adhered to the soft sediments. The adhered bottom will affect the effective height of the mining vehicle's grousers, causing the effective height of the grousers to decrease, which in turn leads to a decrease in the traction of the deep-sea mining vehicle and slipping, resulting in the serious consequence that the deep-sea mining vehicle cannot travel normally. Because the operating environment of deep-sea mining vehicles is in the deep sea, the environment is extremely complex and changeable. Once slipping occurs, it will be extremely difficult to carry out rescue work.

[0003] The geological conditions of deep-sea polymetallic nodule deposits require submarine crawler mining vehicles to operate in a significantly different environment than traditional crawler mining vehicles. These differences are primarily due to the soft, thin soil layers, high porosity, high compressibility, and low bearing capacity of the substrate. Consequently, the soft, thin sediments in deep-sea waters cannot provide the power required by traditional crawler mining machines. Furthermore, the complex seabed topography, with nodule mining areas often experiencing slopes and obstacles, can easily cause mining vehicles to sink, slip, and have difficulty navigating obstacles, resulting in operational difficulties and reduced mining efficiency. Therefore, existing technologies require further refinement and improvement. Summary of the Invention

[0004] In view of the deficiencies of the above-mentioned prior art, the purpose of the present invention is to propose a deep-sea mining vehicle with viscosity reduction and anti-skid functions, so as to solve the problem that when the existing mining vehicles are traveling in the deep sea, soft sediments accumulate between the grousers, causing the effective height of the grousers to decrease, thereby causing the deep-sea mining vehicles to slip and sink, making it difficult to carry out rescue operations in the deep-sea environment.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0034] By adopting the above technical solution, the beneficial technical effect of the present invention is as follows: the present invention adopts a rolling mechanism to first squeeze the thin and soft sediments on the seabed to form a mud layer with a certain degree of compactness. Air bags are arranged on both sides of the crawler teeth. When the crawler presses over the compacted sediments again, the air bags are squeezed by the compacted sediments and deformed. After the crawler teeth leave the ground, the air bags recover their deformation. The contact area between the compacted sediments and the air bags is small, and the water flow disturbance causes the compacted sediments to fall off. The water ripple-shaped coating has the effect of reducing adhesion, eliminating the retention of thin and soft sediments on the crawler, and avoiding slipping. BRIEF DESCRIPTION OF THE DRAWINGS

Each group of jet nozzles 33 includes two rows of jet nozzles 33 arranged one above the other. Each row of jet nozzles 33 includes jet nozzles 33 arranged in a transverse order. Each jet nozzle 33 in the same group is connected to a water supply branch pipe 35. The two water supply branch pipes 35 are connected to a high-pressure pump provided on the frame 1 through a water supply main pipe.

[0051] The top of the collection hood 31 is fixedly connected to the actuator end of the first adjustment mechanism, which drives the collection hood 31 up and down. Specifically, the mounting plate 51 of the first adjustment mechanism is fixedly connected to the top of the collection hood 31 via two sets of first guide rods 36 arranged symmetrically in front and back. Each set of first guide rods 36 includes at least two first guide rods 36 arranged laterally and spaced apart.

Multiple pressure sensors 43 are regularly embedded on the circumferential surface of the roller wheel 41. The signal terminals of the pressure sensors 43 are communicatively connected to the electronic control system.

[0054] The top of the rolling mechanism 4 is fixedly connected to the actuator end of the second adjustment mechanism on the same side, and the second adjustment mechanism can drive the rolling mechanism 4 to rise and fall. Specifically, the mounting plate 51 of the second adjustment mechanism is fixedly connected to the top of the wheel frame 42 by bolts via two sets of second guide rods 44 arranged symmetrically in front and back. Each set of second guide rods 44 includes two second guide rods 44 arranged laterally and spaced apart. The second guide rods 44 are dynamically sealed to the bottom plate of the sealing box 5 via the same sealing sleeve. The rolling mechanism 4 rolls as the mining vehicle moves forward. The rolling process can compact the soft sediment and reduce the adhesion of the soft sediment after the crawler tracks of subsequent mining vehicles pass by. The function of the pressure sensor 43 is to monitor the bearing capacity of the soft sediment under the rolling wheel 41 in real time, so that the rolling wheel 41 can compact the soft sediment below to a certain bearing capacity, facilitating the subsequent shearing of the crawler teeth.

[0055] The crawler walking unit 2 includes a crawler beam 21, a rubber synchronous belt 22 and a crawler chain. The crawler beam 21 is fixedly connected to the frame 1. The rubber synchronous belt 22 is set on the crawler beam 21 through a synchronous pulley 28. There are multiple synchronous pulleys 28, which are arranged on the crawler beam 21 at intervals in the longitudinal direction. The synchronous pulleys 28 at the front and rear ends are the driving wheel and the driven wheel respectively.

[0056] The track chain is mounted on the outside of a rubber synchronous belt 22, which has an annular air passage 221 running along its length. A metal air tube is fixedly embedded in one side of the synchronous belt 22. One end of the tube is connected to the annular air passage 221, and the other end is equipped with an air nozzle 222. The track chain is composed of multiple track shoes 23, which are hinged end to end. Each track shoe 23 has a grouser 24 in the middle of the side facing away from the rubber synchronous belt 22.

[0057] The middle part of each track shoe 23 is adhered to the outer surface of the rubber synchronous belt 22 and vulcanized into one piece. The rubber synchronous belt 22 is provided with tributaries 223 in the same number as the track shoes 23 and in positions corresponding to each other. A connecting pipe 231 is provided in the middle part of each track shoe 23. The end of each connecting pipe 231 is inserted into the corresponding tributary 223, and its circumferential outer wall is vulcanized into one piece with the rubber synchronous belt 22.

[0058] Two air bags 25 are symmetrically provided on both sides of each grouser 24, and all of the air bags 25 are in communication with the annular air passage 221. Multiple rubber ribs 26 are provided inside the air bags 25. These ribs 26 are spaced apart and arranged sequentially inside the air bags 25. One side of the rubber ribs 26 is connected to the inner wall of the air bags 25, and the other side is connected to the arc surface of the grouser 24. Through holes are provided in the rubber ribs 26.

[0059] The thickness of the grouser 24 decreases from the root to the tip. The grouser 24 is symmetrical, with concave arc-shaped surfaces at the root and on opposite sides of the middle. The airbag 25 is located outside the arc-shaped surface, its edge fixedly and sealed to the side of the grouser 24. An air-filled cavity is formed between the inner side of the airbag 25 and the sidewall of the grouser 24. A rippled coating 27 is applied to both sides of the tip of the grouser 24, extending to the edge of the airbag 25. This rippled coating 27 reduces adhesion.

[0060] The grouser 24 has an inverted Y-shaped channel 241 inside. Two ports of the inverted Y-shaped channel 241 are located on the arc surface of the grouser 24 and communicate with the inner side of the airbag 25. The other port is connected to the annular air channel 221 via a corresponding connecting pipe 231. The annular air channel 221 is filled with gas at a certain pressure and then sealed. The airbag 25 is in an inflated state. The airbag 25 located at the lower layer of the track chain is squeezed by the compacted sediment and deforms. When the track shoe 23 at the lower layer of the track chain reaches above the rearmost synchronous pulley, the airbag 25 recovers its deformation, reducing the contact area with the compacted sediment, and is disengaged under the action of water disturbance.
