Description

Technical Field

[0001] This utility model relates to the field of underwater deployment, and in particular to an underwater cylindrical anchor shell device. Background Technology

[0002] With the continuous development of marine research, there is a growing demand for underwater equipment to conduct long-term, fixed-point detection and monitoring in specific sea areas, for tasks such as hydrological information monitoring, seabed sand and soil research, and underwater cable inspection. To achieve these functions, various underwater devices have been developed, most of which are anchored at a certain depth underwater using anchor blocks and cables. For ease of deployment, the underwater equipment, anchor blocks, and cables are often designed as a single unit, with the underwater equipment contained within the anchor. Once certain conditions are met after submersion, the underwater equipment detaches from the anchor and is anchored again via the cable connecting the two.

[0003] Currently, most underwater equipment is fully enclosed inside the trolley anchor. The anchor cover is opened by explosive bolts or by a motor-driven mechanism to release the equipment from the trolley anchor. The equipment typically needs to be released from the trolley anchor before reaching the bottom. When underwater equipment with a large length-to-diameter ratio is released from the trolley anchor, the large travel distance limits the water depth for deployment, making it unsuitable for shallow water deployment.

[0004] There is currently no effective solution to the above problems in existing technologies. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an underwater cylindrical anchor pod device. Through the cylindrical anchor pod design, the deployment component is positioned between the cylindrical anchor and the end cap. The end cap's restriction on the deployment component is released by an explosive bolt, thereby shortening the travel distance of the deployment component as it exits the cylindrical anchor. This solves the problem of difficulty in deploying deployment components with large length-to-diameter ratios in shallow water areas, as is present in the prior art.

[0006] To achieve the above objectives, this utility model provides an underwater cylindrical anchor shell device, comprising: a cylindrical anchor, the tail end of which has a groove, the interior of which is used to accommodate a portion of the deployment component, and the exterior of which is provided with another portion of the deployment component; a tie rod assembly, one end of which is fitted into the groove, and the other end of which is connected to one side of an end cap via an explosive bolt; the end cap is used to abut against the end of the deployment component located outside the cylindrical anchor; and a controller, which is installed on the other side of the end cap and is used to collect environmental information to control the explosive bolt.

[0007] Further optionally, the tie rod assembly includes: a ball end rod, a threaded rod, and a connecting rod; the spherical end of the ball end rod is fitted into the slot, and the other end is threadedly connected to the threaded rod; one end of the connecting rod is threadedly connected to the threaded rod, and the other end is connected to the end cap by an explosion bolt.

[0008] Alternatively, the two ends of the threaded rod may be a left-hand thread and a right-hand thread, respectively.

[0009] Further optionally, the end cap has a protruding extension plate on the side facing the cylinder anchor; the extension plate has a first bolt mounting hole; the end of the pull rod assembly used to connect with the end cap has a second bolt mounting hole, and an explosion bolt is installed when the first bolt mounting hole and the second bolt mounting hole are aligned.

[0010] Alternatively, the explosive bolt has a stepped cylindrical structure, with an axial threaded blind hole on the end face of the smaller diameter end for screwing in a screw to fix the explosive bolt.

[0011] Optionally, the protruding plate is further provided with a first spring mounting hole; the end of the pull rod assembly used to connect with the end cap is provided with a second spring mounting hole, and a spring is installed when the first spring mounting hole and the second spring mounting hole are aligned.

[0012] Alternatively, the sidewall of the first spring mounting hole is threaded for screwing in a screw as a safety mechanism, and the screw is unscrewed before deployment.

[0013] Optionally, there may be multiple tie rod assemblies, which are evenly distributed between the cylinder anchor and the end cap.

[0014] The above technical solution has the following advantages: Through mechanical design, a semi-enclosed design is achieved for deployment components of different shapes inside the barrel anchor, which can shorten the stroke of the deployment component when it comes out of the barrel anchor during deployment; at the same time, the part exposed outside the barrel anchor can sense the environmental force information during the deployment process in real time, which has the advantage of entering the working state earlier than the fully enclosed design; the mechanism has a simple structure, high reliability, convenient operation, and low processing cost.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address the problem of long disengagement strokes of existing length-to-diameter ratio deployment components from the anchor tube, which is inconvenient in shallow water, this invention provides an underwater anchor tube pod device. Figure 1 This is a structural schematic diagram of the underwater cylindrical anchor shell device provided in this embodiment of the utility model, as shown below. Figure 1 As shown, the device includes: a cylindrical anchor 1, with a slot at its tail end; the interior of the cylindrical anchor 1 is used to accommodate a portion of the deployment component, and the exterior of the cylindrical anchor 1 is provided with another portion of the deployment component; a tie rod assembly 2, one end of which is fitted into the slot, and the other end is connected to one side of an end cap 5 via an explosion bolt 4; the end cap 5 is used to abut against the end of the deployment component 7 located outside the cylindrical anchor 1; and a controller 6, which is installed on the other side of the end cap 5 and is used to collect environmental information to control the explosion bolt 4.

[0023] like Figure 1 As shown, the device includes a cylindrical anchor 1, which provides negative buoyancy to the entire structure, preventing it from drifting away with the current. The cylindrical anchor 1 has an internal cavity, with one end of the deployment component 7 located inside this cavity and the other end located outside the cylindrical anchor 1. That is, part of the deployment component 7 is inside the cavity, and the other part is outside the cylindrical anchor 1, making the entire structure semi-enclosed. The deployment component 7 is connected to the cylindrical anchor 1 by a cable system 8, ensuring that after the deployment component 7 is released, it enters the anchoring transition state via the cable system 8.

[0024] The end face of the deployment component 7 located on the outer side of the cylindrical anchor 1 is limited by the end cap 5 to ensure that the deployment component 7 will not completely detach before deployment. One end face of the end cap 5 is connected to the end of the cylindrical anchor 1 via a tie rod assembly 2, and the other end face is equipped with a controller 6. Specifically, the end of the cylindrical anchor 1 has a groove that fits into one end of the tie rod assembly 2, and one end of the tie rod assembly 2 is embedded in the groove. The end cap 5 is connected to the other end of the tie rod assembly 2 via an explosion bolt 4. The controller 6 is electrically connected to the explosion bolt 4, and the controller 6 can collect information from the environment to provide an action signal for the explosion bolt 4. Figure 2 This is a schematic diagram of the underwater cylindrical anchor pod device after the hatch is opened, as provided in this embodiment of the utility model. Figure 2 As shown, when the deployment parameters are met, the controller 6 gives the action signal of the explosive bolt 4, the explosive bolt 4 breaks, the end cap 5 disengages from the tie rod assembly 2, and the limit is released. At this time, the deployment component 7 is released from the cylindrical anchor 1 by positive buoyancy, the cylindrical anchor 1 sinks to the bottom, and the deployment component 7 is moored on the cylindrical anchor 1 by the cable 8, thus achieving anchoring and mooring at a certain water depth.

[0025] As an optional implementation method, Figure 3 This is a structural schematic diagram of the tie rod assembly provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the tie rod assembly 2 includes: a ball head rod 21, a threaded rod 22, and a connecting rod 23; the ball end of the ball head rod 21 is fitted into a slot, and the other end is threadedly connected to the threaded rod 22; one end of the connecting rod 23 is threadedly connected to the threaded rod 22, and the other end is connected to the end cap 5 by an explosion bolt 4.

[0026] like Figure 3 As shown, the tie rod assembly 2 includes a ball-end rod 21, a threaded rod 22, and a connecting rod 23. The threaded rod 22 has threaded grooves at both ends. One end of the ball-end rod 21 is spherical and is fitted into the end slot of the cylindrical anchor 1, as shown. Figure 1 As shown, the slot is a spherical shape that fits it. The other end of the ball head rod 21 is rod-shaped with external threads on the outside, which can be screwed into the threaded groove at one end of the threaded rod 22. One end of the connecting rod 23 has external threads on the outside, which can be screwed into the threaded groove at the other end of the threaded rod 22. The other end of the connecting rod 23 is connected to the end cap 5 by an explosion bolt 4.

[0027] As an alternative implementation, the two ends of the threaded rod 22 are respectively a left-hand thread and a right-hand thread.

[0028] The two ends of the threaded rod 22 are left-handed and right-handed threads, respectively, and are connected to the ball head rod 21 and the connecting rod 23. When rotating, the ball head rod 21 and the connecting rod 23 can be tightened or loosened at the same time, so as to ensure that the length of the pull rod assembly 2 can be adjusted when limiting the placement parts 7 of different lengths, so as to ensure that the end cap 5 can effectively limit the placement parts 7.

[0029] As an optional implementation method, Figure 4 This is a cross-sectional structural diagram of the end cap provided in this utility model embodiment. The end cap 5 has a protruding extension plate 51 on the side facing the cylindrical anchor 1. The extension plate 51 has a first bolt mounting hole. The end of the pull rod assembly 2 used to connect with the end cap 5 has a second bolt mounting hole. When the first bolt mounting hole and the second bolt mounting hole are aligned, the explosion bolt 4 is installed.

[0030] like Figure 4 As shown, the end cap 5 has a protruding extension plate 51 on the side facing the cylinder anchor 1, and this extension plate 51 is perpendicular to the end face of the end cap 5. The extension plate 51 also has a first bolt mounting hole, such as... Figure 3 As shown, the tie rod assembly 2 is also provided with a second threaded mounting hole near the end. The first bolt mounting hole and the second bolt mounting hole are set in correspondence. The tie rod assembly 2 and the end cover 5 can be connected by installing the explosion bolt 4.

[0031] As an optional implementation, the explosion bolt 4 has a stepped cylindrical structure, with an axial threaded blind hole on the end face of the smaller diameter end, for screwing in a screw to fix the explosion bolt 4.

[0032] The explosive bolt 4 has a stepped cylindrical structure, consisting of a smaller diameter end and a larger diameter end, and breaks off at the stepped section upon detonation. Correspondingly, the first and second threaded mounting holes are also stepped. An axially oriented threaded blind hole is provided on the end face of the smaller diameter end of the explosive bolt 4. During installation, the explosive bolt 4 can be screwed into the threaded blind hole from the outside using a screw, thereby connecting the tie rod assembly 2 and the protruding plate 51 as a single unit.

[0033] As an optional implementation, the protruding plate 51 is also provided with a first spring mounting hole; the end of the pull rod assembly 2 used to connect with the end cover 5 is provided with a second spring mounting hole, and the spring 3 is installed when the first spring mounting hole is aligned with the second spring mounting hole.

[0034] like Figure 4 As shown, the protruding plate 51 is also provided with a first spring mounting hole, which is located closer to the side of the cylinder anchor 1 than the first bolt mounting hole. Correspondingly, the tie rod assembly 2 is also provided with a second spring mounting hole. When the two are aligned, a compressed spring 3 can be installed. One end of the compressed spring 3 abuts against the bottom of the first spring mounting hole, and the other end abuts against the bottom of the second spring mounting hole. When the explosive bolt 4 breaks, the elastic force of the spring 3 can spring the tie rod assembly 2 away from the deployment component 7, so as to avoid affecting the release of the deployment component 7.

[0035] As an alternative implementation, the sidewall of the first spring mounting hole is threaded for screwing in a screw as a safety mechanism, and the screw is unscrewed before deployment.

[0036] The first spring mounting hole is also threaded. When not in use, the safety screw can be screwed through the spring 3 into the first spring mounting hole of the protruding plate 51 as a safety mechanism. Before deployment, unscrew the safety screw to release the safety.

[0037] As an optional implementation, there are multiple tie rod assemblies 2, which are evenly distributed between the cylindrical anchor 1 and the end cap 5.

[0038] To improve the overall reliability of the device, multiple tie rod assemblies 2 are provided, and these multiple tie rod assemblies 2 are evenly arranged between the cylinder anchor 1 and the end cap 5. Preferably, the number of tie rod assemblies 2 can be 2, 3 or 4.

[0039] The above technical solution has the following advantages: Through mechanical design, a semi-enclosed design is achieved for deployment components of different shapes inside the barrel anchor, which can shorten the stroke of the deployment component when it comes out of the barrel anchor during deployment; at the same time, the part exposed outside the barrel anchor can sense the environmental force information during the deployment process in real time, which has the advantage of entering the working state earlier than the fully enclosed design; the mechanism has a simple structure, high reliability, convenient operation, and low processing cost.

It should be understood that the above content is only a specific embodiment of the utility model and is not intended to limit the scope of protection of the utility model.
