DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Embodiment 1

[0022] like Figure 1-8 As shown, an ore storage device is mainly used in a mining vehicle (underwater), comprising an ore bin body 1, and a feed port 3, a discharge port and an ore bin door 4 installed at the discharge port arranged on the ore bin body 1. In order to obtain the ore situation in real time during underwater mining, the ore bin observation system 8 for observing the ore collection situation and ore quality, and an underwater weighing module 9 for realizing real-time detection of underwater mining output are provided in the ore bin body 1 in this embodiment.

[0023] Specifically, the above-mentioned mine bin observation system 8 includes, but is not limited to, an underwater lighting 801 and a camera 802. The underwater lighting 801 and the camera 802 are fixedly installed in the mine bin body 1 through a mounting bracket. The underwater lighting 801 is located on one side of the camera 802. By increasing the brightness inside the mine bin body 1, it is ensured that the camera 802 can collect clear and reliable images or video information. When the mining vehicle stops moving or collecting, and stands still for a period of time, the ore collection situation in the bin can be observed through the camera 802 inside the mine bin. The camera 802 signal is connected to the mining vehicle optoelectronic composite cable through a data transmission line, and then transmitted back to the surface deck control room in real time.

[0024] The underwater weighing module 9 in this embodiment is used to monitor the underwater mining situation in real time. A serial distributed design is adopted, including at least four groups of weighing sensors, two of which are located on both sides of the ore bin body 1, such as the lower ends of the two support arms 7, and the remaining two groups of weighing sensors are located in the middle of the ore bin body 1, between the lower ends of the two support points and the connection points of the main frame, and are arranged up and down. The specific position distribution of the four groups of weighing sensors is shown in the figure as the four points A, B, C, and D. The ore bin is installed on the mining platform and supported by four groups of sites. When the ore bin is empty or fully loaded, its center of gravity is always in the vicinity of the center of the four sites A, B, C, and D to avoid excessive uneven load distribution at the four support points A, B, C, and D. The four groups of weighing sensors are installed directly below the four groups of support sites.

[0025] Each of the above-mentioned weighing sensor devices includes at least an upper weighing sensor 901 and a lower weighing sensor 903. The upper weighing sensor 901 and the lower weighing sensor 903 are installed in an upper and lower vertical serial structure, and combined with the installation positions of the four weighing sensor devices, a serial distributed dual backup design is realized.

[0026] Specifically, the upper end of the upper weighing sensor 901 in this embodiment is fixedly connected to the supporting structure at the bottom of the ore bin body 1 by fasteners (such as bolts), and the lower end of the lower weighing sensor 903 is fixedly connected to the supporting structure of the ore bin body 1 on the main frame of the external mining vehicle by fasteners (such as bolts). The supporting structure of the ore bin body 1 is a structure on the mining vehicle for fixing and installing the ore bin body 1, and the upper weighing sensor 901 and the lower weighing sensor 903 are vertically bolted through the sensor connecting seat 902.

[0027] The data collected by each weighing sensor device is transmitted back to the surface control center through watertight data lines, mining vehicle sensor docking boxes and optical fiber cables.

[0028] The entire ore bin main body 1 (mining vehicle) production detection system forms two independent ore weighing systems through the upper weighing sensors 901 at the four points A, B, C, and D and the lower weighing sensors 903 at the four points A, B, C, and D, thereby realizing redundant backup of ore weighing data.

[0029] When detecting ore production, the weight readings of two sets of weighing systems consisting of upper weighing sensors 901 and lower weighing sensors 903 installed at the locations A, B, C, and D in the figure are summed up respectively to obtain two independent sets of total ore weight readings. These two sets of independent weight readings can both verify and back up each other.

[0030] In addition, in order to facilitate the calibration of the underwater weighing module 9, at least two groups of sleepers or I-beams 103 for fixing standard counterweights 101 are fixedly connected in the ore bin body 1 in this embodiment, and the readings of the upper weighing sensor 901 and the lower sensor 903 are corrected by adding or removing the standard counterweights 101. In addition, weldments 102 are provided on both sides of the sleepers or I-beams 103, and the weldments 102 are fixedly connected to the ore bin body 1 to support the sleepers or I-beams 103.

[0031] In order to maintain the balance of this embodiment during operation, the two groups of sleepers or I-beams 103 are symmetrically distributed with the middle of the ore bin body 1 (as shown in the figure) as the center.

[0032] In this embodiment, the cross-section of the side of the ore bin body 1 is an inverted right-angled trapezoidal structure, or a wedge-shaped structure, and the bottom surface structure of the ore bin body 1 is designed to be inclined, so as to facilitate the ore to slide and be discharged from the ore bin body 1.

[0033] Each wall of the ore bin body 1 is a mesh plate, or a mesh structure, which is used to filter out the mud and sand impurities brought into the ore bin body 1, and to discharge the water injected by the ore delivery pipe in time to avoid impact on the inside of the ore bin body 1. The mesh size is mainly determined by the characteristic size of the stored ore. The diameter of the preferred mesh hole is not greater than 70% of the characteristic size of the ore. For example, the mesh hole diameter for storing polymetallic nodule ore is about 5-9 mm. The mesh diameter size setting takes into account that it can fully filter the mud and sand impurities in the ore bin body 1 and exclude the injected water flow, and can effectively prevent the ore from falling out of the bin. At the same time, it also takes into account the irregular shape of the ore and the uneven size distribution. In order to ensure that the ore bin body 1 has sufficient strength and rigidity, the outside of each ore bin wall of each ore bin body 1 is also provided with (or integrally formed) a mesh plate slat 2 as a reinforcing rib for structural reinforcement.

[0034] There are at least two feed ports 3, which are arranged on the top of the ore bin body 1, and the two feed ports 3 are symmetrically distributed with the middle of the top surface of the ore bin as the center (as shown in the figure). The ore is conveyed to the mud-water separation cabin by the water flow of the ore conveying pipe, and after impacting the mud-water ore separation net, it falls into the ore bin body 1 from the feed port 3 for storage. The feed ports 3 are arranged in a left-right symmetrical manner, so that the ore can be fed and stored evenly, avoiding the asymmetry of the left and right center of gravity of the ore bin body 1.

[0035] In this embodiment, at least two hydraulic cylinders 6 (preferably underwater hydraulic equipment) are included on both sides of the mine bin body 1, and the mine bin door 4 is opened and closed by the extension and contraction of the hydraulic rod. The two hydraulic cylinders 6 are respectively located on both sides of the mine bin body 1 and are symmetrically distributed with the middle of the mine bin body 1 as the center, and are preferably connected to the mine bin body 1 by a hinge base.

[0036] The mine bin door 4 is located at the rear of the mine bin body 1 , the top of the mine bin door 4 is hinged to the mine bin body 1 , and the hydraulic rods of the two hydraulic cylinders 6 are hinged to the near middle positions of both sides of the mine bin door 4 .

[0037] A support arm 7 is provided at the bottom of the ore bin body 1, and two support points are provided in the middle. The four support points formed by the two support points and the two support arms 7 can evenly and stably support the entire ore bin structure.

[0038] In addition, a baffle 5 is provided (or abutted) in the discharge port and at the bottom of the ore bin body 1, and a groove for inserting the baffle 5 is provided on the ore bin body 1 to fix the baffle 5. When the ore bin door 4 cannot be closed normally due to a mechanical failure, the baffle 5 can prevent all ore from being discharged.

[0039] The main body 1 of the mine bin in this embodiment is welded by profiles, and is bolted to the frame of the mining vehicle through the hydraulic cylinder 6 and the support point, so as to facilitate subsequent maintenance, disassembly and transportation. The material of the main body 1 of the mine bin is preferably a light aluminum alloy with anti-corrosion properties, so as to reduce the overall weight of the mine bin.

[0040] When storing and unloading the ore, the ore is transported to the ore bin for storage through the ore bin feed port 3. When the ore needs to be unloaded, the ore bin door 4 is opened and closed by the oil cylinders on both sides of the ore bin to discharge the ore inside the ore bin.

[0041] Embodiment 2

[0042] Based on the first embodiment, this embodiment aims to realize an ore production monitoring system, and the detection steps are as follows: S100: Correcting the reading of the underwater weighing module 9; S200: After the correction is completed, the ore in the ore bin body 1 is weighed.

[0043] Step S100 includes: S110: Arrange a counterweight baffle 5 in the ore bin body 1; S120: Prepare standard counterweight 101; S130: Record the system signal reading of the weighing module when the ore bin body 1 is empty ; S140: Place weight Standard counterweight 101, record the system signal reading of the weighing module ; S150: add standard counterweight blocks 101 in sequence, and the weight is recorded as , record the system signal readings of the weighing module in turn ; S160: Calculate the weighing coefficient of weighing sensor 901 ; ; When the underwater weighing reading is , the actual weight in the ore bin is ; .

[0044] The above calculation formula for the weight of the ore bin introduces multiple sets of calibration data. Compared with single-point or two-point calibration, it can reduce the reading deviation of the weighing sensor and improve the accuracy and stability of the overall calibration. Eliminate the effects of environmental changes, small zero point offsets caused by equipment assembly, etc. The above two embodiments realize ore storage and quick unloading in the deep-sea mining process through the grid-shaped and wedge-shaped plate frame ore bin body 1, and realize real-time monitoring of the relevant information of the underwater mining process of the mining vehicle on the water surface through the distributed underwater weighing module 9, and then perform reasonable and correct operation of the mining vehicle.

[0045] It can avoid the situation that the mining head cannot be adjusted properly and cannot be collected normally, or excessive mining causes the ore bin and flow pipe to be blocked, and then damages the relevant structures and equipment of the mining vehicle. It effectively solves the engineering problems of ore collection, storage and weighing in deep-sea mining, ensures the efficient and safe operation of deep-sea mining equipment, and provides technical support for the future automation of deep-sea mining.

[0046] 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.
