Description

Technical Field

[0001] This utility model relates to the field of deep-sea marine environmental noise monitoring, specifically to a deep-sea layered modular underwater mooring platform. Background Technology

[0002] With the deepening of research into deep-sea hydrological environments and underwater target detection, the types and numbers of equipment used for multi-element marine sensing data acquisition and target detection are increasing daily. Simultaneously, the power demand for these devices operating for extended periods in the deep sea is also growing, requiring a considerable number of batteries. Submarine mooring platforms must provide a platform for the equipment and a safe and reliable support system for the deployment and retrieval of the moorings. Different types of mooring platforms carry different equipment. Buoys made of buoyancy materials with a density less than water and resistance to water pressure provide buoyancy for the moorings. These buoys, along with the platform's support frame and hoisting structure, form the mooring platform.

[0003] Submersible moorings are generally divided into anchored and bottom-mounted types. Anchored moorings have a platform and anchoring structure in sections. The platform is connected to the release device and the gravity anchor. By adjusting the length of the connecting rope, the platform is moored at a certain depth in the water. Bottom-mounted moorings have a platform and anchoring structure that are integrated into one piece. The release device and the gravity anchor are directly integrated into the platform. After deployment, the mooring lands on the bottom.

[0004] Depending on the deep-sea operation mission, the mooring platform will carry different numbers and weights of equipment during actual use. Traditional mooring platforms are usually customized individually, and the buoyancy and load they can provide cannot be adjusted. The equipment they carry is fixed and does not have the flexibility of being reused.

[0005] As the scale of equipment carried by underwater gliders increases, the volume and weight of individual floats also increase. Single-buoy underwater gliders face challenges: firstly, their excessive weight and size make assembly and machining inconvenient; secondly, large floats are composed of multiple bonded buoys, and uneven bonding can introduce air bubbles, posing a risk of cracking and damage under the high pressure of the deep sea. Furthermore, the adhesive, with a density greater than glass microspheres, increases the overall density of the buoys, negatively impacting buoyancy-to-weight ratio. Finally, the structural strength of individual buoys differs between metal components and buoyancy materials; when these two materials are in direct contact and subjected to simultaneous stress, the difference in strength and deformation between the two materials increases the risk of cracking.

[0006] Dividing a single large float into multiple float blocks effectively solves the problems of difficult installation and processing of large floats, facilitates the bonding and processing of smaller float blocks, and reduces air bubble formation. Simultaneously, individual float blocks can also be used as buoyancy modules with fixed buoyancy as needed. The submersible platform is modularly divided into a buoyancy platform and a load platform, with both the buoyancy layer and load layer being adjustable. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a deep-sea layered modular underwater mooring platform. It realizes the modular design and reliable assembly of the deep-sea mooring buoyancy and load platform, and can be used flexibly according to the number and size requirements of the equipment carried. It has the characteristics of versatility and reusability.

[0008] The objective of this invention is achieved through the following technical solution: This deep-sea layered modular underwater mooring platform comprises:

[0009] A hoisting platform is installed on top of the underwater mooring platform;

[0010] At least one buoyancy platform is set below the launching platform. Each buoyancy platform is equipped with a float frame, and a float is set inside the float frame to provide buoyancy for the underwater mooring platform. Release devices are set on both sides of the buoyancy platform, and release chains are suspended below the release devices.

[0011] At least one load platform is set below the buoyancy platform. Each load platform is equipped with a load platform frame, and the test equipment is mounted inside the load platform frame.

[0012] Support rods, connected to the four corners of the launching platform, pass sequentially through corresponding positions on the floating body frame and the load platform frame, connecting the launching platform, buoyancy platform, and load platform in series to form the main body of the underwater mooring platform; and

[0013] A base anchor is positioned below the load platform. This base anchor is equipped with an adjustable distance mechanism for attaching to the release chain. By shortening the distance between the adjustable distance mechanisms, the release chain is tightened, causing the buoyancy platform to be pressed against the base anchor, thus achieving integral deployment. When the release device is released, the release chain disengages from the base anchor, causing the load platform to separate from the base anchor, thus achieving abandonment.

[0014] As a further technical solution, the top of the hoisting platform is provided with a hoisting frame, and several hoisting rods are connected below the hoisting frame. A float pressure plate is provided below the hoisting rods to press the float; elastic gaskets are installed between the hoisting platform and the buoyancy platform, and between the buoyancy platform and the load platform.

[0015] As a further technical solution, the floating frame adopts a cuboid frame-type plate beam structure, with four vertical tubes corresponding to the four corners of the floating frame for the support rods to pass through, and symmetrical release bases in the middle of the floating frame for installing the release device.

[0016] As a further technical solution, four vertical pipes are also set at the four corners of the load platform frame for the support rods to pass through. The load platform frame is equipped with an equipment mounting plate, and several equipment bases are installed on the equipment mounting plate to support the equipment clamps. The test equipment is tightened by the equipment clamps. The equipment bases, equipment clamps and equipment mounting plates are replaced according to the equipment installation interface. A release protection plate is set in the middle of the load platform frame to separate the release chain from the test equipment. The release protection plate is a thin plate with multiple holes.

[0017] As a further technical solution, the pitch adjustment mechanism includes a pitch adjustment screw and a pitch adjustment release ring whose distance to the pitch adjustment screw is adjustable. The pitch adjustment release ring is sleeved on the release chain, and the pitch adjustment screw and the pitch adjustment release ring are connected by threads to achieve pitch adjustment.

[0018] As a further technical solution, the release hooks installed at the beginning and end of the release chain are respectively connected to the bottom of the release device, and the release chain passes through the adjustable release ring to connect the buoyancy platform and the base anchor into one unit.

[0019] As a further technical solution, the base anchor also includes an anchor base, a base positioning pin, and a vibration damping spring. The anchor base serves as a landing base and a counterweight for the underwater buoy, while also acting as a ballast. The base positioning pin is set on the anchor base at the four corners of the base anchor to cooperate with the four vertical pipes of the buoyancy platform for installation and positioning. Vibration damping springs are sleeved around the outer periphery of the base positioning pin.

[0020] As a further technical solution, the length of the support rod is adjusted according to the number of layers or height of the buoyancy platform and the load platform. A lifting block is set at the top of the support rod and an anchor limiting tube is set at the bottom. The anchor limiting tube is vertically fitted into the positioning pin of the base, thereby limiting the horizontal displacement of the base anchor. The vibration damping spring is sleeved on the outside of the anchor limiting tube and is in a compressed state.

[0021] As a further technical solution, the float is composed of multiple independent layered floats. Several layers of glass fiber are wound and bonded to the outer surface of the layered floats to form a glass fiber shell. The layered floats have equipment mounting cavities for mounting some equipment of the underwater glider. The uppermost layered float has a cable hole for the interconnecting cable between the buoyancy platform and the load platform to pass through. The float frame base and the top of each layered float are provided with float positioning posts. The bottom of each layered float is provided with a corresponding float positioning cap for aligning and cooperating with the float positioning posts, so that multiple layered floats can be stacked vertically.

[0022] As a further technical solution, a float fixing rod is provided on the base of the float frame for passing through each layer of floats in sequence, and the top of the layered floats is pressed by a float fixing plate; an elastic pad is placed between the float fixing plate and the layered floats to make the force between the float fixing plate and the layered floats uniform; a carbon fiber tube is bonded to the inner wall of the through hole of the float fixing rod in the layered float.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. The number of layers of the buoyancy platform and the load platform can be adjusted according to the scale of the equipment carried. Combined with the base anchor and the hoisting platform, it can be finally installed as a multi-layered underwater mooring platform, which is more flexible.

[0025] 2. The support rod connects the hoisting platform, buoyancy platform and load platform in series to form the main body of the underwater mooring platform, and elastic pads are installed between the three to help the underwater mooring platform cushion its bottom and protect the instruments and equipment. The length of the support rod can be flexibly adjusted according to the number of layers or height of the buoyancy platform and load platform installed, making it more versatile.

[0026] 3. The buoyancy platform is located above the load platform and can provide overall buoyancy to the mooring platform, increase the center of buoyancy, and help the mooring maintain a vertical attitude in the seawater;

[0027] 4. The float is composed of multiple independent layered floats stacked sequentially. The number of layers can be adjusted according to the actual buoyancy required, which facilitates processing and assembly. In addition, the layered floats are made of pressure-resistant buoyancy materials with a density less than water, such as glass micropillars, and several layers of glass fiber of a certain thickness are wrapped and bonded to the outer surface to form a glass fiber shell, which can effectively prevent it from breaking under the high pressure environment of the deep sea. The surface is coated with brightly colored antifouling paint to prevent marine organisms from attaching and to help with discovery at sea.

[0028] 5. The release baffle is a thin plate with multiple holes. Its main purpose is to prevent the release chain from swinging and damaging the relevant equipment on the load chamber platform when the release device is unhooked.

[0029] 6. The vibration damping spring is sleeved on the outside of the anchor limiting tube and is in a compressed state. On the one hand, it can reduce vibration when the mooring platform sits on the bottom, and on the other hand, it can apply an upward thrust to the mooring platform when the release device releases the base anchor, so as to prevent the mooring from sinking into the seabed silt and being unable to rise and be recovered.

Detailed Implementation

[0038] The present invention will now be described in detail with reference to the accompanying drawings:

[0039] Example: As attached Figures 1-7 As shown, this deep-sea layered modular underwater mooring platform includes a deployment platform 1, a buoyancy platform 2, a load platform 3, a base anchor 4, a release device 5, a release hook 6, a release chain 7, a support rod 8, an elastic gasket 9, a lifting block 10, an anchor limiting tube 11, a lifting frame 1-1, a lifting rod 1-2, a float pressure plate 1-3, a float frame 2-1, a float 2-2, a float lifting rod 2-3, an equipment installation cavity 2-4, a cable hole 2-5, an embedded nut 2-6, and a release base 2-7. Layered float 2-8, fiberglass shell 2-9, float fixing rod 2-10, carbon fiber tube 2-11, float fixing plate 2-12, elastic pad 2-13, float positioning cap 2-14, float positioning column 2-15, load platform frame 3-1, equipment base 3-2, equipment clamp 3-3, release protection plate 3-4, equipment mounting plate 3-5, anchor base 4-1, base positioning pin 4-2, vibration damping spring 4-3, adjusting screw 4-4, and adjusting release ring 4-5.

[0040] Reference Appendix Figure 1 , 2The launching platform 1 is located on top of the underwater mooring platform. A lifting frame 1-1 is installed on top of the launching platform 1 to facilitate the connection of an external vertical array. Several lifting rods 1-2 are connected below the lifting frame 1-1. A float pressure plate 1-3 is installed below the lifting rods 1-2 to secure the floats 2-2. Elastic gaskets 9 are installed between the launching platform 1 and the buoyancy platform 2, and between the buoyancy platform 2 and the load platform 3, to help the underwater mooring platform cushion its landing and protect the instruments and equipment.

[0041] like Figure 1 , 2 As shown in Figure 4, the buoyancy platform 2 (in this embodiment, it is one layer, but it can also be multiple layers) is set below the hoisting platform 1. Each layer of the buoyancy platform 2 is provided with a float frame 2-1, and a float 2-2 is set inside the float frame 2-1 to provide buoyancy for the underwater platform. Both sides of the buoyancy platform 2 are provided with release devices 5, and release chains 7 are suspended below the release devices 5.

[0042] Further, see attached document. Figure 2 , 4 The float 2-2 is composed of multiple independent layered floats 2-8 (the number of layers is adjusted according to the actual buoyancy required). The main material of the layered floats 2-8 is a pressure-resistant buoyancy material with a density less than water, such as glass micropillars. Several layers of glass fiber with a certain thickness are wrapped and bonded to the outer surface of the layered floats 2-8 to form a glass fiber shell 2-9, which can effectively prevent it from breaking under the high pressure environment of the deep sea. The surface is coated with brightly colored antifouling paint to prevent marine organisms from attaching and to help with discovery at sea.

[0043] The layered float 2-8 has an equipment mounting cavity 2-4, which can accommodate some of the underwater mooring equipment. The uppermost layered float 2-8 has a cable-passing hole 2-5 for the interconnecting cable between the buoyancy platform 2 and the load platform 3 to pass through. Furthermore, the buoyancy platform 2 can carry some of the underwater mooring equipment, such as equipment that must face the sea surface or cannot be obstructed by the float 2-2. This equipment can be installed in the equipment mounting cavity 2-4 of the layered float 2-8. A fiberglass pad is installed at the bottom of the cavity to support the weight of the equipment. The uppermost layered float 2-8 can be equipped with an embedded nut 2-6 as an interface for equipment installation, and the cable-passing hole 2-5 facilitates the passage of the interconnecting cable between the buoyancy platform 2 and the load platform 3.

[0044] The base of the float frame 2-1 and the top of each layer of floats 2-8 are equipped with float positioning posts 2-15, and the bottom of each layer of floats 2-8 is equipped with a corresponding float positioning cap 2-14, which can be aligned and cooperate with the float positioning posts 2-15 to vertically stack multiple layered floats 2-8. During assembly, first align the bottom layer of floats 2-8 with the float positioning cap 2-14, and use the float lifting rod 2-3 to lift the bottom layer of floats 2-8 into the float frame 2-1. Then, align the floats 2-15 one by one to vertically stack multiple layered floats 2-8. The float positioning cap 2-14 and the float positioning post 2-15 facilitate alignment during the lifting and installation of the layered floats 2-8.

[0045] A float fixing rod 2-10 is installed on the base of the float frame 2-1. The float fixing rod 2-10 can pass through each layered float 2-8 in sequence, and the layered floats 2-8 are pressed down by a float fixing plate 2-12. An elastic pad 2-13 is placed between the float fixing plate 2-12 and the layered floats 2-8 to ensure uniform force distribution between them. A carbon fiber tube 2-11 is bonded to the inner wall of the through hole of the float fixing rod 2-10 in the layered float 2-8 to prevent direct contact between the two and uneven force distribution that could damage the floats.

[0046] Furthermore, the floating frame 2-1 adopts a cuboid frame-type plate beam structure, with four vertical tubes corresponding to the four corners of the floating frame 2-1, through which the support rods 8 can pass. Figure 4 As shown, a symmetrical release base 2-7 is provided in the middle of the floating frame 2-1, which can be used to install the release device 5.

[0047] Reference Appendix Figure 1 , 2 5. The load platform 3 (in this embodiment, it is a single layer, but it can also be multiple layers) is located below the buoyancy platform 2. Each layer of the load platform 3 is equipped with a load platform frame 3-1. The load platform frame 3-1 carries the test equipment. The main function of the load platform 3 is to carry the test equipment, such as sensors, battery compartments, and electronic compartments. It can also serve as a ballast layer for the mooring platform, reducing the center of gravity of the mooring platform and helping the mooring platform maintain a vertical attitude in seawater. Four vertical pipes are also set at the four corners of the load platform frame 3-1, through which the support rods 8 can pass. The load platform frame 3-1 is equipped with an equipment mounting plate 3-5. Several equipment bases 3-2 are installed on the equipment mounting plate 3-5, which can support the equipment clamps 3-3. The test equipment is secured by the equipment clamps 3-3. The equipment base 3-2, equipment clamp 3-3 and equipment mounting plate 3-5 are replaced according to the equipment installation interface; the load platform frame 3-1 is provided with a release protection plate 3-4 in the middle to separate the release chain 7 from the test equipment. The release protection plate 3-4 is a thin plate with multiple holes. Its main purpose is to prevent the release chain 6 from swinging and damaging the relevant equipment on the load platform 3 when the release device 5 is unhooked.

[0048] like Figure 1 , 2 As shown in Figures 3, 6, and 7, the base anchor 4 is positioned below the load platform 3. This base anchor 4 is equipped with an adjusting mechanism that can be fitted onto the release chain 7. By shortening the spacing of the adjusting mechanism, the release chain 7 is tightened, causing the buoyancy platform 2 to be pressed against the base anchor 4, achieving integrated deployment. When the release device 5 releases, the release chain 7 disengages from the base anchor 4, separating the load platform 3 from the base anchor 4, thus achieving abandonment. Furthermore, the adjusting mechanism includes an adjusting screw 4-4 and an adjusting release ring 4-5 whose distance from the adjusting screw 4-4 is adjustable. The adjusting release ring 4-5 is fitted onto the release chain 7, and the adjusting screw 4-4 and the adjusting release ring 4-5 are connected by threads to achieve adjustment. Release hooks 6 installed at both ends of the release chain 7 are connected to the bottom of the release device 5. The release chain 5 passes through the adjusting release ring 4-5, connecting the buoyancy platform 2 and the base anchor 4 to form a single unit.

[0049] Furthermore, the base anchor 4 also includes an anchor base 4-1, a base positioning pin 4-2, and a vibration damping spring 4-3. The anchor base 4-1 serves as a landing base and a counterweight for the underwater buoy, while also acting as ballast. It is made of stainless steel or other metal materials. The base positioning pin 4-2 is located on the anchor base 4-1 at the four corners of the base anchor 4, and can cooperate with the four vertical pipes of the buoyancy platform 2 to achieve installation positioning. The vibration damping spring 4-3 is sleeved around the outer periphery of the base positioning pin 4-2.

[0050] Support rods 8 are connected to the four corners of the launching platform 1 and pass sequentially through the corresponding vertical pipes on the floating body frame 2-1 and the load platform frame 3-1, connecting the launching platform 1, the buoyancy platform 2, and the load platform 3 in series to form the main body of the mooring platform. The length of support rods 8 can be flexibly adjusted according to the number of layers or height of the installed buoyancy platform 2 and load platform 3. A lifting block 10 is set at the top of the support rods 8 and an anchor limiting tube 11 is set at the bottom. The anchor limiting tube 11 is vertically fitted into the base positioning pin 4-2, thereby limiting the horizontal displacement of the base anchor 4. The vibration damping spring 4-3 is sleeved on the outside of the anchor limiting tube 11 and is in a compressed state. On the one hand, it can reduce vibration when the mooring platform sits on the bottom. On the other hand, it can apply an upward thrust to the mooring platform when the release device releases the base anchor, preventing the mooring from sinking into the seabed silt and being unable to rise and be recovered.

[0051] Preferably, in addition to being placed on the seabed with an integrated base anchor 4, the mooring platform can also be equipped with a split anchoring structure to achieve deep-sea fixed-depth mooring.

[0052] The working process of this utility model:

[0053] This utility model consists of a hoisting platform 1, a buoyancy platform 2, a load platform 3, and a base anchor 4, from top to bottom. The buoyancy platform 2 and load platform 3 can be modularly assembled according to the actual equipment requirements, satisfying equipment loading needs while allowing for corresponding adjustments to the buoyancy and gravity ratios. The floats 2-2 of the buoyancy platform 2 are installed in layers (using a layered float block 2-8 design), with the number of layers adjusted according to the required buoyancy. The layered float blocks 2-8 on the buoyancy platform 2 are limited by float block fixing rods 2-10 and float block fixing plates 2-12 fixed to the base of the float frame 2-1, with carbon fiber tubes 2-11 separating the float blocks from the floats. Furthermore, the floats 2-2 are hollowed out to form cavities (equipment mounting cavities 2-4) to facilitate the installation and storage of various equipment. A fiberglass pad is installed at the bottom of the equipment mounting cavity 2-4, and an embedded nut 2-6 is provided at the top of the floats 2-2 to facilitate the installation of various equipment. Each layer of buoys 2-8 is equipped with a buoy lifting rod 2-3 and a buoy positioning post 2-15, enabling alignment and assembly during layering. Several layers of fiberglass of a certain thickness are wound and bonded to the outer surface of each buoy 2-8, forming a fiberglass shell 2-9, effectively preventing it from cracking under the high pressure of the deep sea. This shell is then coated with a brightly colored antifouling paint to prevent marine organisms from adhering and to aid in discovery at sea. This mooring platform can be deployed with an integrated base anchor or with a separate anchoring structure for mooring in seawater.

[0054] This utility model is used as a mooring platform for a deep-sea marine environmental noise mooring monitoring system. The mooring platform is equipped with self-contained hydrophones, ADCP, TD, CTD and other equipment, realizing the deep-sea fixed-depth mooring of multiple noise moors.

[0055] This utility model adopts a modular design, which allows for flexible assembly based on the scale of the equipment being carried and the ratio of buoyancy and gravity, facilitating transportation. The single large float is divided into multiple layered floats, and the use of carbon fiber and glass fiber materials improves the reliability of the float design and installation, effectively preventing damage to the floats due to uneven stress or high water pressure during deployment and retrieval. Combined with an integrated or segmented anchoring structure, the underwater mooring platform can be deployed on the seabed or moored in seawater, offering advantages in versatility and reusability.
