Description

Technical Field

[0001] This utility model relates to the field of underwater test power supply technology, specifically to an auxiliary kit for underwater equipment testing. Background Technology

[0002] Underwater equipment testing refers to simulating the actual operating environment of underwater equipment by placing it at a specified depth in water, while simultaneously conducting tests on the equipment's performance and other related aspects. Currently, testing underwater equipment typically requires the connection of cables such as fiber optic cables to obtain power, transmit or receive signals, etc.

[0003] However, existing underwater equipment typically requires the connection of multiple fiber optic cables to achieve different testing purposes. This leads to numerous problems when the entire system faces complex underwater environments after connecting multiple sets of cables. For example, in areas with strong currents, cables are easily impacted by the current, causing them to become entangled, displaced, or even broken, affecting the normal conduct of underwater tests. Furthermore, the deployment and retraction of the multiple sets of fiber optic cables before and after the start of underwater testing is difficult to coordinate, potentially resulting in entanglement or even damage to the cables during this period. Utility Model Content

[0004] This utility model provides an auxiliary kit for underwater equipment testing, which can constrain multiple cables connected to underwater equipment during testing and simultaneously assist the underwater equipment in carrying out relevant performance tests at a specified depth.

[0005] This utility model is achieved through the following technical solution:

[0006] An auxiliary kit for testing underwater equipment includes: a test cable assembly comprising several sets of test cables connected to the underwater equipment; a levitation kit comprising an equipment levitation component and a cable levitation component; the equipment levitation component includes a levitation device and a suspension component connecting the levitation device and the underwater equipment; the cable levitation component includes a main cable connected to the levitation device, several sets of first levitation blocks laid on the main cable, and a binding component; wherein the test cable includes a first working section and a second working section, when the underwater equipment is in a test state, the first working section connected to the underwater equipment is placed below the water surface, and the second working section is placed above the water surface by being installed on the cable levitation component through the binding component.

[0007] As a further improvement of this utility model, the cable suspension component also includes an auxiliary cable, one end of which is connected to the main cable and the other end of which is connected to the underwater equipment, and the binding component is provided on the auxiliary cable.

[0008] As a further improvement of this utility model, the auxiliary cable is characterized in that a plurality of second suspension blocks are arranged on the auxiliary cable.

[0009] As a further improvement of this utility model, the cable suspension component also includes an extension cable, a plurality of third suspension blocks arranged on the extension cable, and the binding component; the test cable group also includes a plurality of test extension cables; wherein the test extension cables are fixed to the extension cables by the binding component.

[0010] As a further improvement of this utility model, the extension cable is further provided with a fourth suspension block, and the fourth suspension block is provided with a support surface for supporting the docking part provided on the test extension cable and / or the test cable.

[0011] As a further improvement of this utility model, the suspension component includes several sets of first suspension ropes, a set of second suspension ropes, and several sets of third suspension ropes; wherein, one end of each set of first suspension ropes is connected to the levitation device, and the other end is connected to the second suspension rope; one end of the second suspension rope away from the first suspension rope is connected to the underwater equipment; one end of each set of third suspension ropes is connected to the second suspension rope, and the other end is connected to the underwater equipment.

[0012] As a further improvement of this utility model, the test cable includes, from the inside out, a conductive core wire, an insulation layer, a metal shielding layer, and a wear-resistant protective layer.

[0013] As a further improvement of this utility model, it also includes a deployment cable, one end of which is connected to the underwater equipment.

[0014] As a further improvement of this utility model, the deployment cable is connected to the underwater equipment through the suspension member.

[0015] As a further improvement of this utility model, a suspension element is provided at the end of the deployment cable away from the underwater equipment.

[0016] This utility model's auxiliary kit for underwater equipment testing firstly provides power and transmits signals to the underwater equipment through a test cable group consisting of several sets of test cables. Secondly, the equipment suspending component in the suspending kit causes the underwater equipment to be suspended at a specified depth in the water to carry out relevant performance testing. Finally, the cable suspending component constrains the second working section, which accounts for a large proportion of the length of the test cable, and forces it to be suspended on the water surface. On the one hand, placing the test cable on the water surface can reduce the impact of unpredictable water turbulence, thereby significantly reducing the possibility of damage caused by the entanglement of multiple sets of test cables. On the other hand, it also makes it easier for users to observe the movement of the test cable and make judgments on operations such as cable reeling and deployment.

[0017] In the preferred structure, the auxiliary cable and its binding components included in the cable suspension component can also constrain the first working section placed underwater, further reducing the impact of water turbulence and other conditions on the test cable, and reducing the possibility of the test cable getting tangled.

[0018] Furthermore, in the preferred structure, several sets of test extension cables that provide extension function for the test cables can also be constrained by fixing them to the extension cables. This not only reduces the possibility of damage caused by tangling, but also facilitates the release and recycling of the test extension cables. Attached Figure Description

[0019] The accompanying drawings are provided below to illustrate the preferred embodiments of this utility model, in order to aid in understanding the purpose and advantages of this utility model, wherein:

[0020] Figure 1 A schematic diagram of the auxiliary kit for underwater equipment testing;

[0021] Figure 2 A schematic diagram showing the layout of auxiliary kits for underwater equipment testing during the testing of underwater equipment.

[0022] Figure 1 In this structure, the second working section of the test cable is relatively short. Since multiple test cables will connect to multiple points on the underwater equipment, to ensure proper connection between the test cables and each point on the underwater equipment, excessive binding components are not used to over-constrain the second working section. If the second working section is long, then binding components are needed to constrain the portion of the second working section away from the underwater equipment. The accompanying drawing only illustrates one usage scenario mentioned in the embodiment and does not affect the scope of protection of the claims; furthermore, Figure 1 To facilitate the demonstration of the test cables, the first working section of some test cables is not bound to the main cable, and this change does not affect the scope of protection of the claims. Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0025] Example 1:

[0026] This embodiment provides an auxiliary kit for underwater equipment testing, comprising two main parts: a test cable group 1 and a levitation kit 2. The test cable group 1 is used to provide power and transmit signals to the underwater equipment A participating in the test, while the levitation kit 2 is used to maintain the levitation state of the underwater equipment A and to assist in fixing the test cable group 1 to ensure the smooth conduct of the test of the underwater equipment A.

[0027] Among them, the test cable group 1 includes several sets of test cables 101 that are connected to the underwater equipment A, such as... Figure 1 As shown, in this embodiment, underwater device A requires connection to a total of four test cables 101 to conduct relevant tests; the levitation kit 2 includes a device levitation component 201 and a cable levitation component 202, as shown... Figures 1-2 As shown, the equipment suspension component 201 includes a suspension device 201-1 and a suspension component 201-2 connecting the suspension device 201-1 and the underwater equipment A. The cable suspension component 202 includes a main cable 202-1 connected to the suspension device 201-1, several sets of first suspension blocks 202-2 laid on the main cable 202-1, and a binding component 202-3. In this embodiment, the binding component 202-3 can be a component such as a cable tie for fixing the test cable 101. When the underwater equipment A is suspended at a specified depth to carry out relevant test work, the first working section 101-1 of the test cable 101 connected to the underwater equipment A will be placed below the water surface B, while the second working section 101-2 of the test cable 101 will be installed on the cable suspension component 202 through the binding component 202-3 and placed at the water surface B.

[0028] When testing underwater equipment A, it needs to be suspended to a specified depth, and then the control equipment set on the operating vessel C is connected to underwater equipment A through test cable 101. Usually, the distance between the operating vessel C and underwater equipment A is relatively far, which means that the first working section 101-1 of the test cable 101 usually occupies a large proportion of its total length. In this embodiment, the cable suspension component 202 can constrain the first working section 101-1 on several sets of test cables 101 and keep it on the water surface B. On the one hand, this avoids damage caused by unpredictable water flow disturbances underwater, such as tangling and knotting between multiple sets of test cables 101, which would interfere with the test. On the other hand, the user can clearly observe the condition of most of the test cables 101 on the water surface B, such as whether the test cables 101 are damaged, so that preliminary troubleshooting can be carried out as soon as possible in case of abnormalities in the test. At the same time, after constraining several sets of test cables 101 using the main cable 202-1, it is also convenient to carry out the overall winding and unwinding of the test cable group 1, avoiding tangling between the test cables 101 during the winding and unwinding stage, which would make the work difficult to carry out smoothly.

[0029] Preferably, such as Figure 1 As shown, the cable suspension component 202 also includes an extension cable 202-6, several sets of third suspension blocks 202-7 arranged on the extension cable 202-6, and the binding component 202-3. Correspondingly, the test cable group 1 also includes several sets of test extension cables 102; wherein the test extension cables 102 are fixed to the extension cables 202-6 by the binding components 202-3. In this structure, the distance between the operating vessel C and the underwater equipment A is compensated by the extension cable 202-6 and the test extension cables 102, which allows the test cable 101 directly connected to the underwater equipment A and the cable suspension component 202 close to the underwater equipment A to adopt a style with a smaller overall length.

[0030] During the testing of underwater equipment A, the test cable 101 and other components need to be connected to underwater equipment A before it is deployed. Therefore, test cables 101 and cable suspension components 202 with smaller overall lengths can be used, thereby reducing the overall size of underwater equipment A and its auxiliary components. This further reduces interference during the deployment and retrieval phases of underwater equipment A, lowering the difficulty and increasing the speed of deployment and retrieval operations.

[0031] Meanwhile, since the test cable 101 and the test extension cable 102 can be placed on the water surface B by means of the buoyancy provided by the first suspension block 202-2 and the third suspension block 202-7 respectively, the connection operation between the two is simpler, and the user does not need to dive into the water to find the connection point. This structure also allows the user to replace the extension cable 202-6 and the test extension cable 102 with different lengths and styles to adapt to different operating distance test requirements, thus making the underwater equipment testing auxiliary kit more versatile. In this embodiment, the main cable 202-1 and the extension cable 202-6 can be connected to each other using connectors such as D-type shackles.

[0032] Preferably, such as Figure 2 As shown, the extension cable 202-6 is also provided with a fourth suspension block 202-8. The fourth suspension block 202-8 is provided with a supporting surface for supporting the docking portion 101-3 provided on the test extension cable 102 and / or the test cable 101. In this embodiment, both the test extension cable 102 and the test cable 101 are provided with docking portions 101-3. When the two are connected, the docking portions 101-3 are locked together. Therefore, the supporting surface of the fourth suspension block 202-8 can support the docking portions 101-3 of both cables simultaneously. This allows the user to quickly locate the docking portion 101-3 on the water surface B during the test, and to conveniently carry out the connection, disconnection, and connection inspection work between the test extension cable 102 and the test cable 101, thereby improving the efficiency of the test.

[0033] Preferably, such as Figure 1As shown, the suspension component 201-2 includes several sets of first suspension ropes 201-2a, one set of second suspension ropes 201-2b, and several sets of third suspension ropes 201-2c. In this embodiment, there are a total of two sets of first suspension ropes 201-2a and two sets of third suspension ropes 201-2c. One end of each set of first suspension ropes 201-2a is connected to the levitation device 201-1, and the other end is connected to the second suspension rope 201-2b. The end of the second suspension rope 201-2b away from the first suspension rope 201-2a is connected to the underwater device A. One end of each set of third suspension ropes 201-2c is connected to the second suspension rope 201-2b, and the other end is connected to the underwater device A. This structure ensures the connection between the suspension component 201-2 and the underwater equipment A. Even if a small number of the first suspension ropes 201-2a or the third suspension ropes 201-2c are not securely connected, the remaining ropes can still maintain a secure connection for a period of time, preventing the underwater equipment A from sinking immediately and causing damage. Simultaneously, this structure, through multiple sets of third suspension ropes 201-2c at different points on the top of the underwater equipment A, provides an upward pull, keeping the underwater equipment A as horizontal as possible even below the water surface B, thus meeting the requirements for conducting certain tests.

[0034] Preferably, the test cable 101 comprises, from the inside out, a conductive core wire, an insulation layer, a metal shielding layer, and an abrasion-resistant protective layer. This structure ensures that the test cable 101 itself possesses strong signal transmission capabilities and abrasion resistance, reducing the possibility of test failure due to damage to the test cable 101 itself during the underwater equipment A test.

[0035] Preferably, such as Figures 1-2 As shown, the auxiliary kit for underwater equipment testing also includes a deployment cable 3, one end of which is connected to the underwater equipment A. With this structure, when testing underwater equipment A, it is first lowered to a designated height using a lifting device via the deployment cable 3. Then, a suspending device 201-1 is placed on the water surface B, and a suspension member 201-2 connects the suspending device 201-1 to the underwater equipment A to keep it suspended at a designated depth. This structure and related steps allow for a slower descent of underwater equipment A, preventing damage from collisions with hard objects in the water during rapid descent.

[0036] Preferably, such as Figures 1-2As shown, the deployment cable 3 is connected to the underwater equipment A through the suspension member 201-2. Taking this embodiment as an example, multiple sets of third suspension ropes 201-2c are fixedly connected to the underwater equipment A at different points on the top of the underwater equipment A. The deployment cable 3 is also connected to the underwater equipment A through the suspension member 201-2. Therefore, the underwater equipment A can be lowered and raised by the deployment cable 3, and can also be kept as horizontal as possible to meet the requirements of some tests.

[0037] Preferably, such as Figure 2 As shown, a suspension element 301 is provided at the end of the deployment cable 3 that is away from the underwater equipment A. After the underwater equipment A is deployed, the deployment cable 3 can be removed from the lifting device and the vessel carrying the lifting device can be removed. At this time, the deployment cable 3 can be placed directly in the water. The suspension element 301 fixed on it prevents the deployment cable 3 from sinking to the bottom of the water as a whole, making it easy for users to quickly find the deployment cable 3 and carry out recovery work during the lifting phase of the underwater equipment A.

[0038] Example 2:

[0039] This embodiment provides an auxiliary kit for underwater equipment testing, which differs from Embodiment 1 in that, as Figure 1 As shown, the cable suspension component 202 also includes an auxiliary cable 202-4. One end of the auxiliary cable 202-4 is connected to the main cable 202-1, and the other end is connected to the underwater device A. The binding component 202-3 is installed on the auxiliary cable 202-4. When the underwater device A is deployed at a greater depth, the second working section 101-2 of the test cable 101 in the water is also relatively long. Therefore, the second working section 101-2 can also be constrained by the auxiliary cable 202-4 and its binding component 202-3, further reducing the possibility of entanglement between the test cables 101. Preferably, the constraint on the second working section 101-2 occurs on the part of it away from the underwater device A. This is because, Figure 1 Taking underwater equipment A as an example, the test cable group 1 needs to be connected to multiple connection points on underwater equipment A, which are scattered. Therefore, in order to ensure a smooth connection between the two, the end of the second working section 101-2 that is close to underwater equipment A is not subject to overall constraint.

[0040] Preferably, such as Figure 1 As shown, several sets of second suspension blocks 202-5 are arranged on the auxiliary cable 202-4. This structure provides buoyancy for the entire auxiliary cable 202-4, allowing it to maintain a buoyant position. Figure 1 The vertical, straight layout shown in the diagram allows the laying direction of the auxiliary cable 202-4 to be constrained by buoyancy, thus reducing the possibility of it becoming entangled.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
