When preparing before the test, the ore is placed in the funnel-shaped hopper 0202 and transported to the feeding box 0204 through the ore conveying pipe 0203 by its own gravity. The multi-layer ore drop baffle 0205 welded on the inner wall of the box facilitates the dropping of the ore and avoids the squeezing and stacking of the ore. Among them, the topmost ore drop baffle 0205 is an arc-shaped structure with a raised middle part, which facilitates the ore to flow to both ends of the ore drop baffle 0205.

The roller motor 0301 is used to drive the conveyor belt 0302 to move forward, and the speed is adjustable. By driving the ore arrangement roller 0206 to rotate, the conveyor belt 0302 is linked to run. There is enough length from the ore placement starting position of the conveyor belt 0302 to the collection head position for collection, and the width is equal to or less than the width of the collection head mechanism 04, so that the conveyor belt can transport ore at a certain speed in the direction of the collection head mechanism 04. The support roller 0303 is mainly a roller structure, which is installed on the conveyor belt bracket 0305 and supported at the lower part of the conveyor belt 0302 that carries the ore. It is used to carry the ore on the conveyor belt and can rotate freely with the conveyor belt. The electric lifting device 0304 is provided with several and connected to the conveyor support 0305, preferably adopting an electric jack structure, and the electric lifting device 0304 can be lifted and lowered by the rotation of the screw driven by the motor to adjust the distance between the bottom of the collection head cavity 0401 and the ore. The conveyor belt side baffles 0306 are installed on both sides of the conveyor belt 0302 to prevent the ore from falling sideways during the movement. A brush is also installed at the bottom of the conveyor belt side baffles 0306 to prevent the ore from falling into the gap.

[0028] The collection head mechanism 04 is installed on the ore collection box 05, including the collection head cavity 0401, the front jet tube 0402, the rear jet tube 0403, the ore collection and delivery pipe 0404, the annular jet tube 0405, the pressure sensor 0406, and the flow sensor 0407.

The annular jet tube 0405 is connected to the annular jet pump 0506 through a hose with a flange. The ore collection and delivery pipe 0404 is used to transport the collected ore. The pressure sensor 0406 is located on the collection head cavity 0401 and the ore collection and delivery pipe 0404, and is used to monitor the pressure of the internal water flow. The flow sensor 0407 is installed on the side of the front jet tube 0402, the rear jet tube 0403 and the annular jet tube 0405 to monitor the flow rate output by the axial flow pump.

[0029] The ore collection box 05 is installed on the main frame 01, and is used to support the collection head mechanism 04, accommodate the ore storage hanging basket 06, and install the axial flow pump. Specifically, it includes an ore lifting hose 0501, a collection head bracket 0502, a residual ore collection port 0503, an ore collection box frame 0504, a double-row jet pump 0505, an annular jet pump 0506, a third underwater camera 0507, and a fourth underwater camera 0508. The ore lifting hose 0501 is flange-connected to the ore collection and conveying pipe 0404 to facilitate the replacement of the collection head. The collection head bracket 0502 is used to carry the collection head mechanism 04. The residual ore collection port 0503 is opened at the lower part of the ore collection box frame 0504, so that the uncollected ore can fall into the uncollected ore storage basket 0603. The top of the ore collection box frame 0504 is open, which allows the ore storage basket 06 to be hoisted in and out. The side is used to carry the double-row jet pump 0505 and the annular jet pump 0506. The double-row jet pump 0505 is an electric axial flow pump, which provides a set flow of water to the front jet pipe 0402 and the rear jet pipe 0403, and is used to form a vortex in the collection head cavity 0401 to stir up the ore. The annular jet pump 0506 is also an electric axial flow pump, which provides power for the annular jet pipe 0405 to transport the ore. The water flow direction of the jet pump is shown in FIG.

The collection ore storage basket 0601 is used to store the ore collected in the test. Drainage holes are provided on the sides and bottom of the collection ore storage basket 0601 to facilitate drainage during lifting. The underwater weighing sensor 0604 is installed at the bottom of the collection ore storage basket 0601 to record the weight of the collected ore and connect to the electrical integrated control cabinet 07 on the shore through a cable for communication. The uncollected ore storage basket 0603 is located at the bottom of the collection ore storage basket 0601 and has an opening, which is used to store the uncollected ore. Drainage holes are provided on the bottom and sides of the collection ore storage basket. The metal screen 0605 is installed on the opening of the side wall of the ore collection storage basket 0601 to intercept the ore lifted by the ore lifting hose 0501 and facilitate the passage of water. After multiple tests, when the underwater weighing sensor 0604 shows that the ore in the ore collection storage basket 0601 has reached the threshold or the camera finds that the uncollected ore storage basket 0603 is full, the ore storage basket 06 can be lifted out of the water by connecting the lifting lug 0602 with a crane, and then the ore is poured out and put back into the ore collection box 05 for the next test.

[0030] The electrical integrated control cabinet 07 is installed on the ground and can be controlled by operators on land or on shore to obtain the operating information of the collection test device and operate the collection test device for testing. It has functions such as equipment power supply, frequency conversion control and video transmission.

[0031] The beneficial effects of this embodiment include: 1. Verify the rationality of the design and functional integrity of the collection head: The primary purpose is to verify whether the design of the collection head mechanism 04 of the deep-sea mining vehicle is reasonable and whether its functions are complete through experiments. This embodiment uses the method of fixing the collection head mechanism 04 and conveying ore with the conveyor belt 0302 to simulate the movement of the collection head mechanism 04 during dynamic collection in a deep-sea environment. Considering that the collection head mechanism 04 needs to be replaced during the test and is heavy, the method of fixing the collection head mechanism 04 is adopted in the test. While reducing the collection stroke of the collection head mechanism 04 and the longitudinal size of the test device, and reducing the risk of possible damage to the collection head mechanism 04 during the test, the test effect is also achieved.

[0032] 2. Simulate ore arrangement to improve the authenticity of the test: In order to simulate the real scene of deep-sea ore distribution, this embodiment aims to provide a test device that can simulate the collection efficiency of the collection head mechanism 04 for ore under different ore distribution densities, different ground clearances of the collection head mechanism 04 and different travel speeds of the collection head mechanism 04, so as to select the best working setting. The ore is brought out by the rotation of the ore arrangement drum 0206, which can adjust the longitudinal distribution density of the ore on the conveyor belt 0302 and accurately simulate the distribution of ore in mining areas with different abundances; the electric lifting device at the bottom of both ends of the conveyor belt can adjust the height remotely to match and simulate the different ground clearances and slopes of the collection head mechanism 04 during the seabed collection operation; the travel speed of the conveyor belt can be adjusted by the drum motor 0301, so as to simulate the travel speed of the collection head mechanism 04. It should be noted that although the deep-sea environment is simulated, because the collection head mechanism 04 is an open structure, the surrounding pressure is balanced during the collection process, so there is no need to consider the influence of deep-sea high pressure during the test.

[0033] 3. Improve the flexibility of the test and the reusability of different test scenarios: Traditional collection test devices need to customize the pool or trough according to the size of the collection head mechanism 04. When the size of the collection head mechanism 04 increases, the pool or trough also needs to be readjusted accordingly, and the hardware investment is huge. This test device can be used for testing in water bodies such as docks and swimming pools. There is no need to make repeated hardware investments in the pool or trough, and there is no need to fill and drain water during the test. The test method is flexible and can be used to verify the design rationality of the collection head mechanism 04, as well as to verify the collection efficiency of the mine car in the dock or shallow water. In addition, the use of open water bodies for testing is conducive to eliminating the interference of the pool wall in the water tank experiment on the ore collection test; 4. Modular design, convenient for hoisting, transportation and customized assembly: The present invention focuses on the simplicity and practicality of the structure in design, aiming to reduce manufacturing costs. Its main equipment is located in the main frame 01, which is convenient for hoisting and transportation during testing. When testing the collection head mechanism 04 of different design widths, the conveyor belt can be spliced ​​in the horizontal direction and the main frame 01 can be slightly modified to meet the test conditions.

[0034] 5. Flexible feeding and dumping design, efficient circulating ore collection system: The flexible design of the feeding hose facilitates the flexible arrangement of the feeding port on land. The test personnel can transport the ore on land to the underwater feeding box 0204 through the ore conveying pipe 0203, avoiding the inconvenience of draining the water tank before feeding in traditional tests, and ensuring the continuous supply of ore in the test; after a round of tests, the test personnel can hoist the ore storage basket 06 ashore and empty it according to the feedback of the collected ore weight, and then hoist it back into the ore collection box to start a new round of tests, realizing the recycling of ore, greatly reducing the material consumption and labor costs during the test, and shortening the test time.

[0035] 6. Combine and set the conditions of the collection device and effectively monitor and record various technical indicators during the test: The test personnel can use the electrical integrated control cabinet 07 to set the speed and flow of each axial flow pump, the travel speed of the ore conveyor belt 0302, the height of the electric lifting device 0304 and the speed of the ore arrangement drum 0206 to simulate the combination of different seabed operating conditions that the collection head mechanism 04 may face; at the same time, the pressure sensor 0406 and various cameras are used to monitor and record the water flow rate and pressure at the inlet and outlet of the collection head mechanism 04, the weight of the collected ore, and the collection status of the collection head mechanism 04 during the test, so as to find the optimal condition input corresponding to the collection efficiency under different conditions.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
