Description

Technical Field

[0001] This invention relates to the field of deep-sea equipment testing platform technology, and in particular to a comprehensive debugging and testing platform for deep-sea equipment that can simulate a muddy environment. Background Technology

[0002] As underwater equipment, deep-sea equipment, after final assembly, needs to undergo system integration testing and key performance indicator factory assessment under simulated aquatic environment conditions on land. Only after passing the tests can it be shipped out. In the research of key technologies in the deep-sea field, key system prototypes need to undergo functional feasibility and technical indicator verification, as well as operational safety and reliability assessments under simulated aquatic environment conditions on land, to improve the system's technological maturity. For systems and equipment that come into direct contact with seawater, functional feasibility and operational reliability assessment tests need to be conducted for several days or even dozens of days in simulated sediment-laden aquatic environment conditions on land, to ensure that the system and equipment can operate safely and reliably in the actual seabed sediment environment.

[0003] Currently, the testing of deep-sea equipment or key technology system prototypes in terrestrial aquatic environments is typically conducted in specialized pools such as towing tanks, marine engineering tanks, or maneuvering tanks. There is currently no dedicated, comprehensive testing environment capable of simulating a sedimentary environment for factory commissioning of deep-sea equipment or verification of system prototypes. Conducting these tests in specialized pools presents the following problems: (1) High testing costs. Professional test pools are usually quite large, typically reaching tens of thousands or even hundreds of thousands of cubic meters, resulting in very high operating costs. For tests involving sediment, the sediment environment takes a long time to form and is difficult to maintain, and cleaning and refilling the pool after the test is costly. During the test, the effectiveness of the professional test pool is severely affected.

[0004] (2) The test is difficult. Due to the different requirements of the auxiliary facilities for the test in the professional water tank and the auxiliary equipment for the water environment test of deep-sea equipment technology, different modifications need to be made to the professional water tank according to the test requirements. For example, in order to fix the auxiliary facilities for the test, additional fasteners need to be installed inside or on the outer edge of the water tank, which is technically difficult and also poses a risk of damaging the professional water tank.

[0005] (3) Low testing efficiency. The water environment commissioning test of deep-sea equipment requires multiple cycles of underwater testing, land-based improvement, and underwater testing until there are no faults and the system equipment indicators fully meet the requirements; the key technology prototype needs to be continuously operated and tested in the water environment for several days or even more than ten days. The task of professional pool testing is generally quite full, and deep-sea equipment technology testing needs to be carried out in professional pools whenever possible, resulting in low testing efficiency. Summary of the Invention

[0006] To address the shortcomings of existing production technologies and reduce the cost, difficulty, and efficiency of deep-sea equipment testing, this applicant provides a structurally sound comprehensive testing platform for deep-sea equipment that can simulate a sedimentary environment. This platform is specifically designed for water environment testing of deep-sea equipment and technologies. Through a central partition wall and three-section partitions, it enables simultaneous application and functional expansion of testing environments in both clear and turbid water zones within a single testing platform. Furthermore, the pre-installation of various general-purpose embedded parts, the horizontal partitions, and the setup of the testing area reduce testing difficulty and improve efficiency.

[0007] The technical solution adopted in this invention is as follows: A comprehensive testing and commissioning platform for deep-sea equipment capable of simulating a sediment environment includes a platform body. The platform body has a mixed water zone and a clear water zone inside, as well as a partition wall for separating the mixed water zone and the clear water zone. A detachable baffle assembly is installed on the partition wall, which separates the mixed water zone and the clear water zone into independent sealed spaces. A commissioning area is located next to the clear water zone, and a reclining door assembly is installed between the commissioning area and the clear water zone. Winch cabins are arranged on both sides of the commissioning area. It also includes sealing embedded parts arranged on the platform body, which are used to cooperate with the baffle assembly and the tilting door assembly to form a sealing structure; It also includes multiple equipment embeddings and test embeddings. The equipment embeddings are used to install the platform's own equipment, and the test embeddings are used to install and fix the deep-sea equipment or test prototypes to be tested.

[0008] Its further technical solution lies in: The platform body has a rectangular structure with an open top.

[0009] The sealing components include baffle sealing components and retractable door sealing components. The baffle sealing components are used to form a sealing structure with the baffle assembly, separating the mixed water area and the clear water area, forming a spatial structure that simultaneously simulates mixed water and clear water. The baffle sealing components include a first vertical component and a first horizontal component. The first horizontal component is made of a flat plate and is installed on the partition wall. The first vertical component is made of an L-shaped profile and is set on both sides of the baffle wall. The retractable door sealing component includes a second vertical component and a second horizontal component, both of which are L-shaped. The second vertical component is located on both sides of the outlet of the test area, and the second horizontal component is located at the bottom of the outlet of the test area. Together, they form a "U" sealing surface, which forms a sealing structure with the retractable door assembly, separating the clear water area and the test area, and isolating the test area into an independent test space.

[0010] The baffle assembly includes at least one baffle body, a horizontal sealing element disposed at the bottom of the baffle body, and vertical sealing elements disposed on both sides of the baffle body. The baffle lifting lugs are disposed on the upper sides of the baffle body and are mainly used for lifting the baffle body during assembly and disassembly.

[0011] The retractable door assembly includes a retractable door body, a winch for driving the retractable door body to open and close, and a sealing element disposed on the retractable door body.

[0012] The winch is installed in the winch cabin and connected to the retractable door body via cables and pulley blocks.

[0013] The equipment embedded parts include a camera embedded part for installing a camera device, a retractable door embedded part for installing the retractable door assembly, a pulley embedded part and a pulley embedded part for installing a guide cable and a pulley, and a winch embedded part for installing the winch.

[0014] The test embedded parts include a bottom embedded part set at the bottom of the mixing zone for fixing the test object, a water surface embedded part set outside the mixing zone for fixing the water surface test object, a facade embedded part set on the facade of the mixing zone for installing auxiliary equipment, and a debugging zone embedded part set at the bottom of the debugging zone for fixing the debugging object.

[0015] It also includes a camera device, which is installed on the inner wall of the platform body through an embedded part, for monitoring and recording the test process.

[0016] The platform body also has a baffle wall protruding from the inner facade. The baffle wall is coplanar with the partition wall and is used to assist in the installation and fixation of the baffle assembly.

[0017] The beneficial effects of this invention are as follows: This invention primarily addresses the problems of lacking dedicated testing conditions for comprehensive performance verification of deep-sea equipment before delivery and technical testing and evaluation of prototypes of key systems in the deep-sea field, as well as the high cost, difficulty, and low efficiency of conducting tests using other specialized platforms. Compared to the various problems associated with traditional testing using specialized water tanks, this invention has the following advantages: (1) It can simultaneously simulate both sediment and clear water environments, and conduct experiments with different requirements in parallel. The present invention adopts a technical solution with a baffle assembly in the middle, which can divide the platform into two test areas: a clear water area and a turbid water area, simultaneously simulating both turbid and clear water environments to conduct experiments with different requirements; it can also form a variable environment with a large scale and spatial ratio, realistically simulating the actual working environment of equipment or prototypes. Using the present invention, the testing efficiency of deep-sea equipment or system prototypes can be greatly improved and the resource utilization rate can be increased.

[0018] (2) The present invention, through the reclining door assembly, has the ability to form a dry environment for the test object to be fixedly installed underwater, and the installation efficiency of the test object can more realistically simulate the actual situation of the equipment or prototype operating underwater, making the test preparation more efficient and the test results more reliable.

[0019] (3) The present invention pre-sets various general embedded parts required for the fixed installation of deep-sea equipment or prototype tests, which can facilitate the installation and fixing of various test objects and special bases, eliminate the modification time and cost of using traditional facilities for testing, reduce the difficulty of testing, shorten the test cycle, save test costs, and at the same time eliminate the technical risks of modifying traditional test platforms.

[0056] This invention is a comprehensive debugging and testing platform for deep-sea equipment that can simulate a sediment environment.

It also solves the problems of high difficulty, high cost and low efficiency in using professional test pools for testing, and supports the development of equipment technology in the deep-sea field.

[0057] The present invention has many applications; the following description only selects typical scenarios to illustrate the specific implementation of the present invention.

[0058] (a) Multi-subject test application in multi-environment simulation.

[0059] Multi-environment simulation refers to the invention's simultaneous simulation of conventional aquatic environments and sediment test environments, enabling the conduct of different test subjects under different aquatic environments, such as... Figure 12 As shown. In the initial state, the test area and the debugging area 103 are connected and filled with clean water, as... Figure 2 and Figure 3 As shown. To simulate multiple environmental conditions and maximize the use of this invention in experiments, the baffle assembly 5 was hoisted between the baffle walls 106 and onto the partition wall 105 using a factory lifting device. The baffle assembly 5 and the baffle seals form a sealed structure, separating the mixed water zone 101 from the clear water zone 102 to create two sealed, independent spaces. Subsequently, experimental conditions capable of simulating a silt environment were created in the mixed water zone 101.

[0060] There are two methods for creating sediment environment test conditions. The first is to directly dump sediment to simulate actual seabed geology. The second is to drain the water from the turbid water zone 101 and lay sediment simulating seabed geology at the bottom. For tests that only require a sediment environment and do not require fixed equipment, the first method can be used. For tests that require fixed equipment at the bottom, the second method should be used. The following example illustrates the application of the second method.

[0061] (1) Winch test under simulated silt and sand environment: A water pump is used to drain part of the clear water in the mixed water zone 101 to the clear water zone 102, and the rest is discharged externally. After emptying, a quick-connect base is installed on the bottom embedded part 402, and mud and sand simulating the actual seabed geology are laid at the bottom. A transmission pulley is fixed on the vertical embedded part 403, and a pulley winch and pulley are installed on the water surface base. Cables are passed through the vertical pulley and the water surface pulley respectively, and connected to the pulley winch and the test winch, as shown. Figure 12 As shown. In addition, a hoisting cable that protrudes above the water surface is installed on the test winch. Then, the mixing zone 101 is filled with water using a water pump to create a simulated sediment-laden aquatic environment. After water injection is completed, the pulley winch and test winch are started, and a long-cycle reciprocating pulley test is carried out in the turbid water zone 101. This test examines the safety and reliability of the test winch in the deep-sea sediment environment, tests the design performance, identifies design problems, and improves the technical maturity of the test winch. During the test, the operating status of the test winch is monitored in real time using camera device 7, and the data is transmitted to the surface control room or test control console for display or storage.

[0062] During the test, if any problems are found with the test winch, the test should be stopped immediately, and the cable should be released from the winch to allow it to slack. Using lifting equipment and a hoisting cable, the test winch should be lifted out of the water for equipment inspection or technical upgrades. Afterwards, using lifting equipment, the modified test winch should be redeployed to the mixed water zone 101. With the assistance of real-time monitoring from camera device 7, the test winch should be connected to the quick-connect base and secured, initiating a new phase of testing until all performance characteristics of the test winch meet the design requirements. (2) Performance testing and docking recovery test of AUV under simulated conventional aquatic environment: At this time, the door body 601 is in the open state, such as Figure 3 As shown. Start the winch 607 to pull up the body 601 of the reclining door via the cable, forming a sealed structure with the reclining door sealing embedded part. Use the water pump to drain the water in the test area 103 into the clean water area 102 to form a dry test space. Personnel enter the dry test area 103, install and fix the AUV docking and recovery device to the water surface embedded part 401 of the test area 103, and install the AUV into the docking and recovery device.

[0063] After installation, water is pumped from the clean water area 102 into the test area 103. Once full, the winch 607 is started to release the cable, and the reclining door body 601 tilts towards the clean water area 102 under the constraint of the cable until the reclining door body 601 is flush with the bottom of the platform.

[0064] After the above work is completed, the test is initiated. The docking and recovery device releases the AUV, which then navigates to the clear water zone 102 to conduct navigation, turning, and detection tests to verify system performance. The entire test process is recorded by camera device 7 and uploaded to the surface control console for display and storage. After the test, the AUV navigates to the test area 103 to conduct a docking and recovery test to verify the success rate of underwater recovery and docking of the AUV and the accuracy of the signal guidance device.

[0065] The test proceeded smoothly, and the above test was repeated continuously to verify the system's reliability. If any problems were found during the test, the drainage process was repeated, and personnel entered the dry commissioning area 103 to improve or upgrade the equipment. After completion, the process of filling with water and releasing the reclining door body 601 was repeated to start a new round of testing.

[0066] For equipment or key technology prototype testing, the two tests mentioned above can be carried out simultaneously, which greatly improves testing efficiency.

[0067] (ii) Single-subject tests simulating a single environment: For pre-delivery testing or key technology prototype demonstration tests requiring a larger space, the baffle assembly 5 is lifted separately using a factory crane, creating a larger test space between the turbid water zone 101 and the clear water zone 102. Since the water within this invention is in a static state with boundary constraints, the relatively low disturbance in the test, coupled with the partition wall 105 of a certain height, effectively blocks the transfer of most of the sediment in the turbid water zone 101. For test conditions requiring an overall turbid environment, an underwater mixer can be used to stir the water in the turbid water zone 101, significantly disturbing the aquatic environment and achieving overall turbidity in the test area. The following description uses an underwater mothership carrying an ROV for near-seabed underwater exploration as an example to illustrate the specific implementation method.

[0068] For underwater operations carried by an underwater mothership with an ROV, the general process is as follows: the ROV detaches from the mothership's ROV storage compartment and autonomously navigates to the target location on the seabed to prepare for the operation. During this process, the seawater is clear. The ROV operates, stirring up seabed sediment, causing the surrounding environment to become turbid, which gradually spreads to the mothership. After completing the operation, the ROV navigates back to the mothership in the turbid water environment and docks with the storage compartment for recovery. Throughout this process, the ROV is primarily in a turbid water environment.

[0069] For the above operating conditions, the ROV and storage compartment are installed and fixed on the test area embedded part 404 at the bottom of the test area 103. Water from the clear water area 102 is injected into the test area 103 using a water pump, and the cable is released by the winch 607, slackening the cable restraining the reclining door body 601. The reclining door body 601 is then guided to the clear water area 102. Figure 9 As shown. After preparation, the test is initiated. The ROV detaches from the storage tank in a clear water environment and navigates to the turbid water zone 101. Using its onboard detection system, it locates the work target buried or partially buried in silt and begins operations. Due to the disturbance caused by the ROV's operations, bottom silt is stirred up, the water becomes turbid, and this turbidity gradually spreads to the clear water zone 102 and the test zone 103. After the operation is completed, the ROV navigates to the test zone 103 in the turbid water environment and, guided by the docking guidance device between the ROV and the storage tank, docks with the storage tank and returns to the storage tank, thus completing one operation test or demonstration.

[0070] After the sediment in the clear water zone 102 and the test zone 103 settles and the water quality becomes clear, the next test can be started to verify the ROV's operational capabilities for different operational targets and the reliability of docking and recovery in turbid environments.

[0071] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. Within the scope of protection of the present invention, any form of modification may be made.
