Description

Technical Field

[0001] This invention relates to the field of seabed observation and monitoring technology, and in particular to a release device and a seabed environment observation and monitoring system for seabed environment observation and monitoring. Background Technology

[0002] The traditional method for deep-sea seabed observation and sampling is to use an underwater robot (ROV) or winch system to lower the corresponding instruments and equipment to the seabed for monitoring. However, this method cannot achieve long-term in-situ observation. Since it requires the cooperation of large ships, several tens of hours is the limit.

[0003] To enable long-term observation and monitoring of the seabed, deep-sea seabed bases and deep-sea moorings have emerged. Among them, deep-sea seabed bases can monitor environmental elements in the bottom water, while deep-sea moorings can monitor environmental elements in the deep-sea profile.

[0004] In the release devices used in both of the above deep-sea equipment, the counterweights are concentrated at the bottom center of the device, and the tension cables pulling the counterweights are also located at the vertical axis of the device's center. The seabed detection equipment used for observation and monitoring is generally arranged above the counterweights of the release device. This means that after the release device reaches the seabed, the seabed detection equipment is still some distance from the seabed and cannot be used for bottom-based observation. At the same time, since the counterweights are always located directly below the seabed detection equipment, the observation range and viewing angle of the seabed detection equipment are easily affected by the counterweights, thus affecting the comprehensive collection of data. Summary of the Invention

[0005] The purpose of this invention is to provide a release device and a seabed environment observation and monitoring system for seabed environment observation and monitoring. It can achieve in-situ observation of seabed exploration equipment while meeting the requirements for the recovery and release of seabed exploration equipment, and eliminate the influence of counterweights on the observation and monitoring range and viewing angle of seabed exploration equipment, so as to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] On one hand, the present invention provides a release device for seabed environmental observation and monitoring, comprising:

[0008] The main frame has a hollow bottom, and the center of the bottom of the main frame is used to install a seabed detection device with seabed environment observation and monitoring functions.

[0009] The counterweight unit includes a counterweight, counterweight ropes, and a release mechanism. The release mechanism is mounted on the main frame and is located near the top of the main frame. The counterweight is located below the bottom of the main frame and is suspended from the release mechanism by multiple counterweight ropes. Each counterweight rope is located on the outer periphery of the seabed exploration device. The counterweight is distributed around the outer periphery of the seabed exploration device, and the bottom end of the counterweight is flush with the bottom end of the seabed exploration device, so that the seabed exploration device and the counterweight can be placed on the seabed simultaneously.

[0010] A float, connected to the main frame, is used to provide buoyancy to the main frame after the release mechanism releases each of the counterweight ropes, so as to separate the main frame from the counterweights.

[0011] In some embodiments, the main frame is a columnar frame or a tapered frame with the tip pointing upwards, and the counterweight is a closed ring-shaped counterweight arranged coaxially with the main frame.

[0012] In some embodiments, the closed-loop counterweight is an integral ring counterweight, and multiple counterweight ropes are connected at intervals along its circumferential direction on the integral ring counterweight;

[0013] Alternatively, the closed ring counterweight is composed of multiple counterweight blocks connected end to end, and each of the counterweight blocks is connected to a counterweight rope.

[0014] In some embodiments, the main frame is a multi-faceted pyramidal frame, and a guide tube is provided on any one of the edges of the multi-faceted pyramidal frame. The guide tube is used to movably thread the counterweight rope, and the guide tube corresponds one-to-one with the counterweight rope.

[0015] In some embodiments, the top of the pyramidal frame is coaxially provided with a columnar mounting frame, and the top of any one of the guide rope tubes is connected to the columnar mounting frame and extends into the columnar mounting frame;

[0016] The release mechanism is installed inside the columnar mounting frame and is located above the guide rope cylinder;

[0017] The top of the columnar mounting frame is provided with a lug or a lifting ring for connecting the float.

[0018] In some embodiments, the release mechanism includes a release device one, a release device two, and a release rope. The release device one and the release device two are arranged at intervals. One end of the release rope is connected to the release hook of the release device one via a hanging ring, and the other end of the release rope is connected to the release hook of the release device two via the hanging ring.

[0019] The top end of any one of the counterweight ropes is connected to a rope loop that can pass through the inside of the rope guide tube, and the rope loops of all the counterweight ropes are movably looped on the release rope;

[0020] One of the release devices, release device one and release device two, releases the release rope, allowing all the loops of the counterweight pull ropes to slip off the release rope, thereby releasing the counterweight.

[0021] In some embodiments, the top end of any of the guide rope tubes is provided with a horn tube with a guide surface.

[0022] In some embodiments, the closed annular counterweight is provided with a support for supporting the bottom end of the guide rope cylinder, and the support corresponds one-to-one with the guide rope cylinder.

[0023] In some embodiments, the pyramidal frame further includes an upper connecting frame and a lower connecting frame. The upper connecting frame is located near the top of the pyramidal frame and is connected between each of the edge supports. The lower connecting frame is located near the bottom of the pyramidal frame and is connected between each of the edge supports. The bottom end of the lower connecting frame is used to install the seabed exploration equipment.

[0024] A triangular reinforcing plate is provided between any of the edge brackets and the upper connecting frame, and between any of the edge brackets and the lower connecting frame, and a water passage hole is provided on the triangular reinforcing plate.

[0025] On the other hand, the present invention proposes a seabed environment observation and monitoring system, including the seabed detection device and the release device for seabed environment observation and monitoring as described in any one of the above. The seabed detection device is set at the bottom center of the main frame and located in the inner circle of the counterweight. The seabed detection device and the counterweight can be located on the seabed at the same time.

[0026] The present invention achieves the following technical effects compared to the prior art:

[0027] The release device for seabed environmental observation and monitoring provided by this invention has a discardable counterweight deployed around the seabed detection equipment, while the counterweight rope is distributed around the outer perimeter of the seabed detection equipment. This achieves the purpose of placing the seabed detection equipment in the central area at the bottom of the device, which can both meet the deep-sea deployment and retrieval requirements of the device and enable the seabed detection equipment to be observed from the bottom. It plays a key role in meeting the observation and monitoring needs of the seawater-seabed interface.

[0028] In this invention, each counterweight rope is threaded through a guide tube at a corresponding position, which ensures that the counterweight ropes do not interfere with each other or get dragged by other parts during the release process, playing a key role in the release and recovery of the main frame.

[0029] The main frame and column-shaped mounting bracket of this invention adopt a hollow frame as the whole. The diagonal pull of the counterweight rope makes the center and bottom of the frame completely empty, which can accommodate various functional cabins, sensors and other measuring devices, and can expand the observation and monitoring functions and sampling functions of the seabed interface.

[0030] The seabed environment observation and monitoring system proposed in this invention includes the above-mentioned release device and possesses all the features of the above-mentioned release device, which will not be repeated here. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] One of the objectives of this invention is to provide a release device for seabed environmental observation and monitoring, which can achieve in-situ observation of seabed detection equipment while meeting the requirements for the recovery and release of seabed detection equipment, and eliminate the influence of counterweights on the observation and monitoring range and viewing angle of seabed detection equipment, thereby solving the problems existing in the prior art.

[0040] Another objective of this invention is to provide a seabed environmental monitoring system incorporating the aforementioned release device.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] like Figure 1 and Figure 2As shown, this embodiment provides a release device 100 for seabed environmental monitoring, including a main frame 1, a counterweight unit 2, and a float 3. The bottom of the main frame 1 is hollowed out, and the center of the bottom of the main frame 1 is used to install a seabed detection device 300 with seabed environmental monitoring function. The main frame 1 serves as a carrier to transport the seabed detection device 300 to the seabed. The counterweight unit 2 includes a counterweight 21, a counterweight rope 22, and a release mechanism 23. The release mechanism 23 is located on the main frame 1 and near the top of the main frame 1. The counterweight 21 is located below the bottom of the main frame 1 and is suspended from the release mechanism 23 by multiple counterweight ropes 22. Each counterweight rope 22 is located at... The outer periphery of the seabed detection equipment 300 is designed to prevent the counterweight ropes 22 from affecting the detection range and field of view of the seabed detection equipment 300. Simultaneously, counterweights 21 are distributed around the outer periphery of the seabed detection equipment 300, with the bottom of the counterweights 21 flush with the bottom of the seabed detection equipment. This arrangement avoids the counterweights 21 affecting the detection range and field of view of the seabed detection equipment 300, while allowing both the seabed detection equipment 300 and the counterweights 21 to be simultaneously positioned on the seabed, enabling in-situ observation from the seabed. This eliminates the problem in existing technologies where the vertical arrangement of the seabed detection equipment 300 and the counterweights 21 affects the observation range and viewing angle of the seabed detection equipment 300. A float 3 is connected to the main frame 1 and provides buoyancy to the main frame 1 after the release mechanism 23 releases the counterweight ropes 22. This allows the main frame 1 to carry the seabed detection equipment 300 upwards towards the sea surface and separate from the counterweights 21, thus completing the release and retrieval of the seabed detection equipment 300. The counterweight unit 2 mainly provides a sinking pull force for the main frame 1 and the seabed exploration equipment 300 during the process of the main frame 1 driving the seabed exploration equipment 300 to sink and the seabed exploration equipment 300 conducting bottom observation, so as to ensure the smooth progress of bottom observation. After the release mechanism 23 releases each counterweight rope 22, the counterweight 21 and the counterweight rope 22 are discarded on the seabed and do not need to be retrieved.

[0044] In some feasible implementations, the main frame 1 can be a columnar frame or a cone-shaped frame with its tip pointing upwards, and the counterweight 21 is a closed annular counterweight arranged coaxially with the main frame 1. The columnar frame includes, but is not limited to, cylindrical or prismatic frames, while the cone-shaped frame includes, but is not limited to, conical, frustum-shaped, prismatic, and pyramidal frames. To reduce or avoid the main frame 1 from tipping over or overturning during floating and descent in water, a cone-shaped frame is preferred for the main frame 1. The shape of the closed annular counterweight is preferably consistent with the shape of the bottom end face of the cone-shaped frame to reduce the obstruction of the bottom opening of the cone-shaped frame by the counterweight, ensuring the observation range and viewing angle of the seabed detection equipment 300.

[0045] In some feasible implementations, the main frame 1 is preferably a multi-faceted pyramidal frame, and a guide tube 11 is provided on any one edge of the multi-faceted pyramidal frame. The guide tube 11 is used to movably thread a counterweight rope 22, and the guide tube 11 corresponds one-to-one with the counterweight rope 22. For example... Figure 1 and Figure 2 As shown, the main frame 1 adopts a regular square pyramidal frame, which includes four edge supports. Each edge support is equipped with a guide tube 11, or the guide tube 11 can be directly used as the edge support. The guide tube 11 forms a closed channel inside, realizing the built-in "invisible" arrangement of the counterweight rope 22. This not only prevents the counterweight rope 22 from floating due to seawater, thus affecting the suspension stability of the counterweight 21, but also guides the counterweight rope 22 after it is released by the release mechanism, preventing it from being dragged by other parts during the separation of the counterweight rope 22 from the main frame 1. At the same time, it ensures that the counterweight rope 22 does not interfere with each other during the release process, thus not affecting the release and recovery efficiency and effect of the main frame 1. The guide tube 11 plays a key role in the release process of the counterweight rope 22 and the counterweight 21.

[0046] In some feasible implementations, a columnar mounting bracket 12 is coaxially provided at the top of the pyramidal frame (i.e., the main frame 1), and the top of any one of the guide rope tubes 11 is connected to the columnar mounting bracket 12 and extends into the columnar mounting bracket 12. For example... Figure 1 and Figure 2 As shown, the columnar mounting bracket 12 is preferably a cylindrical mounting bracket. In addition, the columnar mounting bracket 12 can also adopt a pyramidal or prismal structure, which can be flexibly adjusted according to the needs.

[0047] In some feasible implementations, the release mechanism 23 is installed inside the columnar mounting bracket 12 and located above each guide rope drum 11, so that the counterweight pull rope 22 extending from each guide rope drum 11 can be connected to the release mechanism 23.

[0048] In some feasible embodiments, the top of the columnar mounting bracket 12 is provided with a lug 13 or a lifting ring for connecting the float 3. The float 3 can be a single float or a combination of multiple floats, which is connected to the lug 13 or the lifting ring by ropes.

[0049] In some feasible implementations, both the columnar mounting frame 12 and the pyramidal frame (i.e., the main frame 1) are preferably made of metal, and the two are preferably welded together to improve the structural stability of the entire frame structure. At the same time, the entire frame is preferably coated with a corrosion-resistant coating to improve the corrosion resistance and service life of the frame underwater, providing a good structural foundation for long-term underwater observation.

[0050] In some feasible implementations, both the columnar mounting frame 12 and the pyramidal frame (i.e., the main frame 1) are hollow inside to facilitate the installation of related detection equipment, power supply equipment, etc. Furthermore, the detection equipment (including the seabed detection equipment 300), power supply equipment, release mechanism 23, etc., are installed inside the columnar mounting frame 12 and the pyramidal frame (i.e., the main frame 1), which fully utilizes the columnar mounting frame 12 and the pyramidal frame (i.e., the main frame 1) to protect the internal components and reduce the impact and damage of seawater on the detection equipment (including the seabed detection equipment 300), power supply equipment, release mechanism 23, etc.

[0051] Some feasible implementation methods, such as Figure 1 and Figure 2 As shown, the release mechanism 23 preferably includes a release device 231, a release device 232, and a release rope 233. Release devices 231 and 232 are arranged alternately. Both release devices 231 and 232 have a release ring at their bottom ends. One end of the release rope 233 is connected to the release hook 234 of release device 231 via a hanging ring 235, and the other end of the release rope 233 is connected to the release hook 234 of release device 232 via another hanging ring 235. Both release devices 231 and 232 can be acoustic release devices, and they are preferably arranged symmetrically at the same height.

[0052] Each counterweight rope 22 has a loop 236 at its top that can pass through the inside of the guide rope cylinder 11. All loops 236 at the top of the counterweight ropes 22 are movably looped onto the release rope 233. Initially, the two ends of the release rope 233 are connected to the release hooks 234 of release device 1 231 and release device 232, respectively. When the main frame 1 needs to be released and retrieved, one of release device 1 231 or release device 232 is driven to release the release rope 233, causing all loops 236 of the counterweight ropes 22 to slip off the release end of the release rope 233, thus releasing the counterweight 21. The release command of release device 1 231 or release device 232 can be remotely driven wirelessly via a controller.

[0053] In some feasible embodiments, the top end of any one of the guide rope drums 11 is provided with a horn-shaped tube 111 with a guide curved surface. The horn-shaped tube 111 can guide the released counterweight rope 22 so that the top end of the counterweight rope 22 and the rope loop 236 can smoothly enter the guide rope drum 11. At the same time, when the counterweight rope 22 is suspended by the release mechanism 23, the counterweight rope 22 is in contact with the horn-shaped tube 111. The guide curved surface of the horn-shaped tube 111 can reduce the wear between it and the counterweight rope 22, which helps to extend the service life of the counterweight rope 22.

[0054] The counterweight rope 22 includes, but is not limited to, traction structures such as buffer ropes and anchor chains.

[0055] In some feasible embodiments, the closed-loop counterweight is also provided with a support 211 for supporting the bottom end of the guide rope cylinder 11, and the support 211 corresponds one-to-one with the guide rope cylinder 11. For example... Figure 1 As shown, an inclined support 211 is provided at each of the four corners of the rectangular closed ring counterweight. The inclined direction of the support 211 is parallel to the guide rope cylinder 11 so that after the closed ring counterweight contacts the bottom end of the pyramidal frame (i.e., the main frame 1), it contacts the bottom end of the guide rope cylinder 11 to support the pyramidal frame (i.e., the main frame 1).

[0056] like Figure 1 As shown, the guide rope cylinder 11 is preferably a cylindrical structure. Correspondingly, each support 211 is preferably a semi-cylindrical bracket, and the inner diameter of the semi-cylindrical bracket is the same as the outer diameter of the guide rope cylinder 11. When the semi-cylindrical bracket supports the guide rope cylinder 11, the two are fitted together with an inner and outer sleeve and a clearance fit. Since the inclination direction of each corresponding set of semi-cylindrical brackets is consistent with that of the guide rope cylinder 11, the semi-cylindrical brackets also play a role in guiding and positioning the guide rope cylinder 11 during the process of the closed ring counterweight being connected to the release mechanism 23 through the counterweight pull rope 22. Even underwater, this prevents relative rotation between the multi-faceted frame (i.e., the main frame 1) and the closed ring counterweight.

[0057] In some feasible implementations, the support 211 is preferably a metal support, which can be fixed to the closed ring counterweight by welding a support block.

[0058] In some feasible implementations, to further improve the structural stability of the main frame 1, the pyramidal frame preferably further includes an upper connecting frame 14 and a lower connecting frame 15. The upper connecting frame 14 is located near the top of the pyramidal frame and is connected between each edge support (i.e., the guide rope cylinder 11). The lower connecting frame 15 is located near the bottom of the pyramidal frame and is connected between each edge support (i.e., the guide rope cylinder 11). The bottom end of the lower connecting frame 15 is used to install the seabed exploration equipment 300. After the seabed exploration equipment 300 is installed, its bottom end slightly protrudes from the lower end face of the main frame 1, with a protrusion thickness not less than the thickness of the closed annular counterweight, to ensure that the seabed exploration equipment 300 can achieve bottom-based observation.

[0059] In some feasible implementations, triangular reinforcing plates 16 are provided between any edge support and the upper connecting frame 14, and between any edge support and the lower connecting frame 15, to enhance the overall structural stability of the main frame 1. Simultaneously, water passage holes 161 are provided on the triangular reinforcing plates 16, which can both meet the lightweight requirements of the main frame 1 and ensure the underwater balance capability of the main frame 1.

[0060] In some feasible implementations, both the upper connecting frame 14 and the lower connecting frame 15 are preferably grid frames, which can meet the lightweight requirements of the main frame 1 and ensure the underwater balance capability of the main frame 1.

[0061] The working process and working principle of the release device 100 used for seabed environmental observation and monitoring are described in [reference needed]. Figure 2 Initially, the two ends of the release rope 233 are connected to the release hooks 234 of release device 1 231 and release device 232, respectively. After the release device 1 231 is given a release command, it performs a release and unhooking action, and the hanging ring 235 at the left end of the release rope 233 detaches from the release hook 234 of release device 1 231. Driven by the float 3, the main frame 1 and the columnar mounting frame 12 float as a whole, while the counterweight 21 remains stationary. During the overall floating process of the main frame 1 and the columnar mounting frame 12, the release rope 233 floats along with the main frame 1, and its release end (i.e., the free end) gradually passes through the loops 236 of all the counterweight pull ropes 22 (which do not float with the main frame 1 because they are connected to the counterweight 21), until the loops 236 of each counterweight pull rope 22 slip off the release rope 233; subsequently, each counterweight pull rope 22 passes through four guide rope tubes 11 during the floating process of the main frame 1. After each counterweight rope 22 is released from its corresponding guide rope cylinder 11, the counterweight 21 is completely detached from the main frame 1 and abandoned on the seabed, thus completing the release process. Finally, the main frame 1 (including the seabed detection equipment 300) floats to the surface under the influence of the float 3 and is further recovered with the assistance of a ship.

[0062] The seabed detection equipment 300 can adopt the in-situ detection device for covering seabed heat flow disclosed in patent CN109187268A. The specific structure and working principle will not be described in detail here.

[0063] In summary, the release device 100 for seabed environmental monitoring of the present invention solves the problem of retrieval and release of seabed monitoring equipment used to achieve long-term in-situ monitoring of the seawater-seabed interface.

[0064] The aforementioned release device 100 for seabed environmental observation and monitoring uses a ring-shaped discardable counterweight, which is placed around the seabed detection equipment 300. At the same time, the counterweight rope is pulled diagonally away from the central area of ​​the device, thereby achieving the purpose of placing the seabed detection equipment 300 in the central area of ​​the bottom of the device. This not only ensures the deep-sea deployment and retrieval requirements of the device, but also enables the seabed detection equipment 300 to be observed from the bottom, playing a key role in meeting the observation and monitoring needs of the seawater-seabed interface.

[0065] Each counterweight rope of the present invention is threaded into a guide tube 11 at a corresponding position, which can ensure that the counterweight ropes do not interfere with each other or get dragged by other parts during the release process, and plays a key role in the release and recovery of the main frame 1.

[0066] The main frame 1 and column mounting frame 12 of the present invention adopt a hollow frame as a whole. The diagonal pull avoidance setting of the counterweight rope makes the center and bottom of the frame completely empty, which can accommodate various functional cabins, sensors and other measuring devices, and can expand the observation and monitoring function and sampling function of the seabed interface.

[0067] This invention has been verified through multiple near-shore tests and deployed in a deep-sea project at a depth of nearly 1,500 meters for nearly three months of in-situ observation and exploration, obtaining a large amount of data and demonstrating good application prospects.

[0068] Example 2

[0069] This embodiment provides a release device 100 for seabed environmental monitoring. The difference between this device and Embodiment 1 is that the closed-ring counterweight is not a single-piece structure, but rather composed of multiple counterweight blocks connected end-to-end, with a counterweight rope 22 connected to each counterweight block. Adjacent counterweight blocks can be connected via hooks, shackles, or other structures. These hooks and shackles are easily detachable, allowing for adjustments to the number of counterweight blocks in the closed-ring counterweight to control its diameter.

[0070] Each counterweight is equipped with a support 211 to provide guidance, positioning and support functions for the guide rope cylinder 11.

[0071] Example 3

[0072] This embodiment proposes a seabed environment observation and monitoring system 200, including a seabed detection device 300 and a release device 100 for seabed environment observation and monitoring as described in Embodiment 1 or 2. The seabed detection device 300 is located at the bottom center of the lower connecting frame 15 in the main frame 1 and is situated within the inner ring of the counterweight 21. The seabed detection device 300 and the counterweight 21 can be simultaneously located on the seabed. The seabed detection device 300 includes, but is not limited to, devices employing CTD sensors, such as the in-situ overlay seabed heat flow detection device disclosed in patent CN109187268A.
