To monitor the environment affected by the plume after mining;

[0038] The sediment collection system is used to collect water particles at different time periods vertically at a fixed point, and is used to monitor the deposition rate and material flux of water particles.

[0039] The large end of the conical cylinder of the sediment collection system is installed at the center of the upper layer of the platform main frame; the acoustic releaser is installed at the edge of the upper layer of the platform main frame; a radio beacon and an optical beacon are installed on the upper layer of the platform main frame through a fixing seat, and the fixing seat is welded on two vertical short support rods and is horizontally oriented;

[0043] The pulley assembly is installed on the inner side of the vertical support leg of the lower layer of the platform main frame, and the pulley assembly is used to install the counterweight assembly.

[0044] The working principle of a small carrier platform that can be used for water particle collection and environmental monitoring in an embodiment of the present invention is as follows: based on the mutual cooperation of the functional system, the control base station and the multiple wireless monitoring nodes, water particles in different periods are collected vertically at a fixed point according to a preset time sequence, and the seabed sampling and environmental monitoring tasks are completed together. A local area network is built to replace the existing electrical cables to transmit data between various detection devices in real time, which saves a large number of data transmission cables for the carrier platform, reduces the weight of the carrier platform, greatly saves the cost of purchasing cables, and greatly reduces the risk of damage to cables due to adverse behaviors such as external collisions. At the same time, an acoustic communication system is configured to cooperate with other underwater monitoring equipment such as base stations to build a deep-sea remote controlled local area network, realize real-time transmission of data image information and the issuance of strategy instructions, adapt to the requirements of seabed topography and seabed detection, monitor the collection of water particles and the environment affected by plumes after deep-sea mining, freely combine seabed detection equipment according to different detection tasks, and adopt a redundant design in the key link of releasing and dumping, use two releasers to dump at the same time, increase the probability of successful dumping of equipment, and provide a guarantee for the successful recovery of the equipment.

[0045] Furthermore, the present application can be equipped with a variety of small chemical sensors such as CTD, ADCP, turbidity, dissolved oxygen, etc. to complete the monitoring of surrounding environmental parameters and data storage; it can be deployed at a fixed point with a cable or released in a free fall without a cable, and recovered by self-floating without power; in addition, the overall equipment is miniaturized, which is convenient for offshore operations, and is equipped with an acoustic communicator and other underwater monitoring base stations to achieve networking.

[0046] This carrier platform is small in size and light in weight. It is equipped with a sediment collection system and many environmental detection equipment and sensors. It has the characteristics of high equipment integration. The data transmission of each detection equipment no longer relies on cable transmission, but relies on a multi-dimensional, high-performance, high-speed two-way transmission underwater local area network composed of other base stations and carrier platforms for data transmission and command transmission.

[0047] The overall solution mainly includes the platform main frame, which is used as a carrier for various functional components. Multiple functional systems and communication nodes are installed on the platform main frame to build a local area network to realize the monitoring of equipment data information, the collection of graphic information and the collection of sediment samples, saving a large number of data transmission cables and effectively improving the reliability and flexibility of various equipment;

[0048] The main frame of the platform is welded with seawater corrosion-resistant metal pipes and plates. The overall external shape is a large cylinder without an outer structure, and several vertical supports are evenly welded around it. The main frame of the platform is arranged with upper, middle and lower layers of different heights.

[0049] The local area network is a reliable local area network with multi-dimensional, high-performance, high-speed two-way transmission characteristics formed between the carrier platform and the base station, other carrier platforms, surface buoy system and shore-based control room, which facilitates the transmission and interaction of commands and data.

[0050] The central part of the platform main frame is in the shape of a small cylinder without an outer structure. The exterior and interior of the platform main frame are welded together using transverse supports; the interior of the platform main frame is welded to each layer of circular rings by several short vertical support rods.

[0051] Specifically, the conical cylinder of the sediment collection system is installed at the center of the upper layer of the platform main frame; the acoustic releaser is installed at the edge of the upper layer of the platform main frame; beacons and cursors are installed between the upper layer and the middle layer of the platform main frame through a fixing seat, and the fixing seat is welded on two vertical short support rods and is horizontally oriented;

[0052] The fixed base of the sediment collection system is installed at the center of the middle layer of the platform main frame, and the small mouth of the conical cylinder, the driving device and the power supply device of the carrying platform are installed on the upper part of the fixed base; a gear pair consisting of a large gear and a small gear is installed on the lower surface of the fixed base, and the small gear is connected to the driving device as a driving wheel to drive the large gear to rotate to realize the collection of sediment;

[0053] The large gear is fixed on the fixed base through a guide plate and a ball bearing, and collection bottle mounting holes and sample collection bottle stations are evenly distributed inside the large gear along the diameter and circumference direction, so as to mount and fix multiple collection bottles and rotate with the rotation of the large gear; the small opening at the lower part of the conical cylinder is only aligned with one sample collection bottle station each time it rotates.

[0054] When collecting samples, the control system of the carrier platform controls the speed of the small gear according to the designed parameters to control the rotation speed of the large gear, thereby controlling the sample collection speed; sample collection is carried out according to a certain time sequence to meet the data collection needs of the carrier platform, and automatically records information such as sample collection time, equipment status self-test results, and battery parameters.

[0055] The release system includes an acoustic releaser installed on the upper layer of the platform's main frame and a mechanical releaser installed on the middle layer of the platform's main frame. The two releasers are connected in parallel and do not affect each other during operation. They are independent of each other. One of the releasers can discard the counterweight after completing the load-dumping action. Each releaser can reliably perform the load-dumping work. The mechanical releaser receives instructions from the master control system to dump the load, and the acoustic release receives instructions from the shore base to dump the load.

[0056] When one of the two releasers fails to work, the other releaser can still reliably throw away the counterweight on the carrier platform.

[0057] After the counterweight system is released and thrown away, the carrier platform floats to the surface of the water relying on the buoyancy provided by the glass float and polymer float material of the buoyancy system. The cursor and beacon system are then exposed to the water surface, and their dormant state is immediately awakened, sending a position signal to the satellite. The shore-based laboratory conducts sea search and salvage based on the position information provided by the satellite to achieve the safe recovery of the carrier platform.

[0058] The polymer float material is installed on the outer side of the upper layer and the middle layer of the platform's main frame, which not only provides partial buoyancy for the carrier platform, but also provides anti-collision protection for the conical cylinder of the sediment collection system. Since the polymer float material itself is a low-density, high-strength, low-water absorption polymer material, it has a certain anti-collision ability, is corrosion-resistant, and can undergo secondary machining, and can meet the use requirements of equipment of various shapes.

[0059] Pulley assemblies of the counterweight system are installed on the inner side of several vertical legs in the lower layer of the platform main frame to facilitate the installation of the counterweight assembly. The counterweight assembly and the pulley assembly together constitute the counterweight system; multiple counterweight assemblies are connected into one by a pulley and connected to the release system through the pulley assembly to ensure that the two releasers are connected in parallel. As long as one releaser in the release system is actuated, the counterweight assembly can be released to achieve the release purpose.

[0060] The counterweight assembly is composed of multiple metal discs that have been precisely designed and calculated to have high density, small size and high cost performance. The metal discs are produced and processed into the required style, which is not only easy to install, but also can be made into the weight required by the carrier platform. It is also convenient to distribute the counterweight equally on each leg, so as to better maintain the posture of the carrier platform when it is deployed and increase the stability of the carrier platform when it is deployed.

[0061] When deploying the carrier platform, it can be deployed at a fixed point with cable using a lifting device on the mother ship, or the base station can be deployed in a free-falling manner without cable using its own counterweight system; when the carrier platform is used in conjunction with other equipment for detection tasks, the fixed-point deployment method with cable should be used, because the position of the carrier platform is relatively controllable during cable deployment, and the bottom position will not be inaccurate due to ocean currents and other reasons. If the detection mission does not require fixed-point deployment or the mother ship does not have the conditions for cable deployment, cable-free deployment can be performed.

[0062] After the detection mission of this carrier platform is completed, the control system will issue a jettison command to jettison the counterweight, and the carrier platform will be recovered in an unpowered self-floating manner through the buoyancy provided by the glass float and polymer float material of its own buoyancy system.

[0063] It is worth noting that since the carrier platform uses a small number of cables, the probability of misconnection of various cables when connecting equipment on the platform is greatly reduced. The probability of cables being damaged due to collision when the platform is laid out and seated is also greatly reduced. The risk of data being unable to be transmitted due to cable damage is also reduced, thereby greatly increasing the working reliability of the platform.

[0064] In summary, a small-sized carrier platform for water particle collection and environmental monitoring in an embodiment of the present invention is based on the mutual cooperation of the functional system, the control base station and the multiple wireless monitoring nodes, collects water particles at different time periods vertically at a fixed point according to a preset time sequence, and jointly completes the seabed sampling and environmental monitoring tasks. A local area network is built to replace the existing electrical cables to transmit data between various detection devices in real time, which saves a large amount of data transmission cables for the carrier platform, reduces the weight of the carrier platform, greatly saves the cost of purchasing cables, and greatly reduces the risk of damage to cables due to adverse behaviors such as external collisions. At the same time, an acoustic communication system is configured to cooperate with other underwater monitoring equipment such as base stations to build a deep-sea remote controlled local area network, realize real-time transmission of data image information and the issuance of strategy instructions, and can adapt to the requirements of seabed topography and seabed detection, monitor the collection of water particles and the environment affected by plumes after deep-sea mining, and freely combine seabed detection equipment according to different detection tasks. A redundant design is adopted in the key link of releasing the dumping load, and two releasers are used to dump the load at the same time, which increases the probability of successful dumping of the equipment and provides a guarantee for the successful recovery of the equipment.

[0065] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.
