Description

TECHNICAL FIELD

[0001] The utility model belongs to the multi -metal nucleus mining equipment technical field, more specifically, it relates to a multi -metal nucleus collection structure and multi -metal nucleus mining equipment. BACKGROUND

[0002] At present, the design principle and structure of multi -metal nucleus collection device are various, wherein the wall -attached jet type collection device utilizes the coanda effect to realize the pickup and lifting of nucleus. This design can effectively separate and lift the nucleus from the sea bottom substrate through the wall -attached effect of fluid near the wall, and the disturbance to the substrate is small, which reduces the damage to the sea bottom environment. However, the wall -attached jet type collection device faces a significant technical challenge in practical application, that is, its sensitivity to the off -bottom height is high. Specifically, the collection efficiency of the device is highly dependent on the off -bottom height between the collection device and the sea bottom substrate, and the off -bottom height interval with high collection rate is very narrow. Once the off -bottom height deviates from this ideal interval, the collection efficiency will decrease rapidly, which seriously affects the recovery effect of multi -metal nucleus.

[0003] In actual sea bottom collection operation, due to the complexity and variability of the sea bottom topography, the off -bottom height of the collection device often fluctuates due to factors such as terrain undulation and bottom substrate softness change. When the off -bottom height increases, the gap between the main body back plate of the collection device and the sea bottom substrate also increases. The expansion of this gap leads to the fact that part of the multi -metal nucleus cannot be effectively captured, but slides away from the gap. With the further increase of the gap, the probability of nucleus sliding away increases significantly, thereby causing the collection rate to decrease sharply. This phenomenon not only reduces the working efficiency of the collection device, but also increases the resource waste and operation cost. UTILITY MODEL CONTENTS

[0008] A guide nozzle is located at the front end of the suction port and is installed at the beginning of the guide curve, the jet direction of the guide nozzle is towards the oblique rear of the suction port and is tangent to the beginning of the guide curve, so as to drive the material to flow along the guide curve to the collection channel;

[0009] A boost nozzle is extended into the collection channel, the jet direction of the boost nozzle is consistent with the extension direction of the collection channel, so as to deliver the material to the guide outlet;

[0010] A lift nozzle is located at the rear end of the suction port, the jet direction of the lift nozzle is towards the oblique front of the suction port, so as to lift the material below the suction port.

[0018] Compared with the prior art, the application has the following beneficial effects:

[0019] The multi-metal nodule collecting structure provided by the application comprises a shell, a guide nozzle, a boost nozzle and a lift nozzle. The shell is the main part of the collecting structure and has a suction inlet and a guide outlet. The suction inlet is located below the guide outlet and is used to suck the multi-metal nodules in the seabed. The shell is also provided with a guide curve and a collecting channel. The guide curve is arranged above the suction inlet and extends to the lower side of the suction inlet in a curved manner. The end of the guide curve is connected to the inner wall of the collecting channel in a tangent manner to form a smooth transition structure to ensure the continuity of the material flow. The guide nozzle is installed at the beginning of the guide curve and is located at the front end of the suction inlet.

At the same time, the jet flow of the lift nozzle produces a reflected flow after contacting the seabed to form an upward lifting force, which re-lifts the fallen nodules into the collecting channel, thereby improving the collecting efficiency. In addition, the water flow baffle formed by the lift nozzle has strong adaptability to the change in the height from the bottom. Even if the height from the bottom changes, the collecting rate can still be kept high, and the stability and reliability of the device in the complex seabed environment are significantly improved.

[0032] As Figures 1 to 3As shown, the present application provides a multi-metal nodule collection structure, which includes a shell 1, a guide nozzle 2, a boost nozzle 3, and a lift nozzle 4. The shell 1 is the main part of the collection structure, which has a suction inlet 11 and a guide outlet 12. The suction inlet 11 is located below the guide outlet 12, which is used to suck the multi-metal nodules in the seabed sediment. The shell 1 is also provided with a guide curve 13 and a collection channel 14. The guide curve 13 is arranged above the suction inlet 11 and extends downwardly to the suction inlet 11, and its end is connected with the inner wall of the collection channel 14 in a tangent manner, forming a smooth transition structure to ensure the continuity of material flow. The guide nozzle 2 is installed at the beginning of the guide curve 13 and located at the front end of the suction inlet 11, and its jet direction is towards the oblique rear of the suction inlet 11 and is tangent to the beginning of the guide curve 13. The multi-metal nodules are driven to flow along the guide curve 13 to the collection channel 14 by the jet fluid, and the pick-up and lifting of the nodules are realized by using the Coanda effect, thereby reducing the disturbance to the seabed sediment. The boost nozzle 3 extends into the inside of the collection channel 14, and its jet direction is consistent with the extension direction of the collection channel 14, which is used to transport the collected multi-metal nodules along the collection channel 14 to the guide outlet 12, ensuring that the nodules can be efficiently and continuously discharged. The lift nozzle 4 is located at the rear end of the suction inlet 11, and its jet direction is towards the oblique front of the suction inlet 11, which is used to lift the material below the suction inlet 11 to avoid the nodules from depositing near the suction inlet 11. During the collection process, part of the multi-metal nodules may fall from the collection channel 14, but the jet flow of the lift nozzle 4 can form a water flow baffle to effectively block the nodules from moving further. At the same time, the jet flow of the lift nozzle 4 produces a reflected flow after contacting the seabed sediment, forming an upward lifting force to re-lift the fallen nodules into the collection channel 14, thereby improving the collection efficiency. In addition, the water flow baffle formed by the lift nozzle 4 has strong adaptability to the change of the height from the bottom, that is, even in the case of the change of the height from the bottom, it can still maintain a high collection rate, significantly improving the stability and reliability of the device in complex seabed environments.

[0033] In a specific embodiment of the present application, the structure of the shell 1 further includes an upper plate 15, a lower plate 16, and a side plate 17. The upper plate 15 is located above the lower plate 16, and the two are connected on both sides by the side plate 17, thereby enclosing the overall frame structure of the shell 1. The upper plate 15, the lower plate 16, and the side plate 17 together constitute the main part of the shell 1, providing stable support and a closed working space for the collection structure.

[0034] In one embodiment of the present application, the polymetallic nodule collection structure further comprises a second flow pipe 6 which is in communication with the boost nozzle 3 for providing the required fluid medium to the boost nozzle 3. Through the connection of the second flow pipe 6 with the boost nozzle 3, the fluid medium can be sprayed out of the boost nozzle 3 at a preset flow rate and pressure to drive the polymetallic nodules to flow along the collection channel 14 to the guide outlet 12.

[0035] In one embodiment of the present application, the polymetallic nodule collection structure further comprises a second flow pipe 6 which is in communication with the boost nozzle 3 for providing the required fluid medium to the boost nozzle 3. Through the connection of the second flow pipe 6 with the boost nozzle 3, the fluid medium can be sprayed out of the boost nozzle 3 at a preset flow rate and pressure to drive the polymetallic nodules to flow along the collection channel 14 to the guide outlet 12.

[0036] In one embodiment of the present application, the polymetallic nodule collection structure further comprises a third flow pipe 7 which is in communication with the lift nozzle 4 for providing the required fluid medium to the lift nozzle 4. The third flow pipe 7 is fixedly connected to the lower plate 16, and through the connection of the third flow pipe 7 with the lift nozzle 4, the fluid medium can form a jet flow to lift the material below the suction inlet 11 and generate a reflected flow to upwardly lift the polymetallic nodules.

[0037] In one embodiment of the present application, the lift nozzle 4 is arranged at an angle with the horizontal direction, and the angle θ ranges from 20° to 60°, aiming to enable the jet flow of the lift nozzle 4 to effectively act on the material below the suction inlet 11, while forming an upward lifting force to improve the collection efficiency of the polymetallic nodules. When the jet flow of the lift nozzle 4 is sprayed at an angle of 20° to 60°, the reflected flow generated after the jet flow contacts the seabed can significantly enhance the lifting effect on the polymetallic nodules, and the water flow baffle formed at the same time can effectively block the backward movement of the nodules, not only improving the adaptability of the device to the variation of the height from the bottom, but also ensuring the stability and high efficiency of the collection operation in complex seabed environment. By reasonably controlling the spraying angle of the lift nozzle 4, the device can maintain a high collection rate under different operation conditions, while reducing the loss of polymetallic nodules.

[0038] The present application also provides a polymetallic nodule mining device comprising the polymetallic nodule collection structure in the above-mentioned embodiments, and thus has the advantages of the polymetallic nodule collection structure in the above-mentioned embodiments.

[0039] The above merely provides the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
