[0002] With the continuous development of ocean research, there is a demand for underwater equipment to conduct long-term fixed-point detection and monitoring in specific sea areas, which is used to perform tasks such as hydrological information monitoring, seabed sand research, and underwater cable detection. In order to achieve the above functions, various underwater equipment have been developed, and most of them are anchored at a certain depth underwater through anchor blocks and cables. In order to facilitate deployment, underwater equipment, anchor blocks, and cables are mostly designed as an integrated whole, that is, the underwater equipment is limited and installed in the anchor. After entering the water and meeting certain conditions, the underwater equipment is removed from the anchor and enters the anchored state through the cable between the two.
[0003] At present, most underwater equipment is fully enclosed inside the anchor barrel, and the anchor cover is blown open by explosive bolts, or the anchor cover is opened by motor drive to disengage the anchor barrel. The underwater equipment is usually disengaged from the anchor barrel before landing. When the underwater equipment with a large length-to-diameter ratio is disengaged from the anchor barrel, the travel is large, and the water depth for deployment is limited, which is not suitable for shallow water deployment.
[0004] There is currently no effective solution to the above problems in the prior art. Summary of the invention
[0005] In order to solve the above problems, the present invention provides an underwater anchor pod device. Through the anchor pod design, the deployment component is arranged between the anchor and the end cover, and the limit of the deployment component by the end cover is released by the explosive bolt, thereby shortening the travel of the deployment component to escape from the anchor, so as to solve the problem of difficulty in deploying deployment components with a relatively large length-to-diameter ratio in shallow water areas in the prior art.
[0006] To achieve the above-mentioned purpose, the present invention provides an underwater barrel anchor pod device, comprising: a barrel anchor, a slot is provided at the tail end of the barrel anchor, the interior of the barrel anchor is used to accommodate a part of the deployment member, and the outside of the barrel anchor is provided with another part of the deployment member; a pull rod assembly, one end of the pull rod assembly is clamped in the slot, and the other end is connected to one side of an end cover through an explosive bolt; the end cover is used to support the end of the deployment member located outside the barrel anchor; a controller, the controller is installed on the other side of the end cover, and is used to collect environmental information to control the explosive bolt.
[0007] Further optionally, the pull rod assembly includes: a ball head rod, a threaded rod and a connecting rod; the spherical end of the ball head rod is clamped in 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 cover by an explosion bolt.
[0008] Further optionally, two ends of the threaded rod are left-handed threads and right-handed threads respectively.
[0009] Further optionally, the end cover is provided with a protruding extension plate on one side facing the barrel anchor; the extension plate is provided with a first bolt mounting hole; the end of the pull rod assembly used for connecting with the end cover is provided with a second bolt mounting hole, and an explosive bolt is installed when the first bolt mounting hole is aligned with the second bolt mounting hole.
[0010] Further optionally, the explosive bolt is a stepped cylindrical structure, and an axial threaded blind hole is provided on the end surface of the small diameter end for screwing in a screw to fix the explosive bolt.
[0011] Further optionally, a first spring mounting hole is provided on the extension plate; a second spring mounting hole is provided at one end of the pull rod assembly for connection with the end cover, and a spring is installed therein when the first spring mounting hole is aligned with the second spring mounting hole.
[0012] Further optionally, the side wall of the first spring mounting hole is provided with a thread for screwing in a screw as a safety mechanism, and unscrewing the screw before deployment.
[0013] Further optionally, there are multiple tie rod assemblies, and the multiple tie rod assemblies are evenly distributed between the barrel anchor and the end cover.
[0014] The above technical solution has the following beneficial effects: through mechanical design, a semi-enclosed design of deployment parts with different shapes in the barrel anchor is realized, which can shorten the travel of the deployment parts out of the barrel anchor during deployment; at the same time, the part exposed outside the barrel anchor can sense the environmental force information of 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, easy operation and low processing cost.

[0023] like Figure 1 As shown, the device includes a barrel anchor 1, which is used to provide negative buoyancy for the entire structure to sink to the bottom of the water, and ensure that the entire device will not float away with the water flow. A cavity is provided inside the barrel anchor 1, one end of the deployment member 7 is located in the cavity, and the other end is located outside the barrel anchor 1, that is, a part of the deployment member 7 is located in the cavity, and the other part is located outside the barrel anchor 1, and the entire structure is a semi-closed structure. The deployment member 7 is connected to the barrel anchor 1 through a cable 8 to ensure that the deployment member 7 enters the anchoring state through the cable 8 after it is released.
[0024] The end face of the deployment piece 7 located at one end outside the barrel anchor 1 is limited by the end cover 5 to ensure that the deployment piece 7 will not completely fall out before deployment. The end face of one end of the end cover 5 is connected to the end of the barrel anchor 1 through the pull rod assembly 2, and the end face of the other end is provided with a controller 6. Specifically, the end of the barrel anchor 1 is provided with a slot adapted to one end of the pull rod assembly 2, and one end of the pull rod assembly 2 is embedded in the slot. The end cover 5 is connected to the other end of the pull rod assembly 2 through an explosive bolt 4. The controller 6 is electrically connected to the explosive bolt 4, and the controller 6 can collect information in the environment, thereby giving an action signal of the explosive bolt 4. Figure 2 FIG. 1 is a schematic diagram of the structure of the underwater anchor pod device after opening the cabin provided by an embodiment of the present invention. Figure 2 As shown, when the deployment parameters are met, the controller 6 gives an action signal to the explosive bolt 4, the explosive bolt 4 is blown off, the end cover 5 is separated from the pull rod assembly 2, and the limit is released. At this time, the deployment component 7 is separated from the barrel anchor 1 by positive buoyancy, and the barrel anchor 1 sinks to the bottom. The deployment component 7 is moored to the barrel anchor 1 through the cable system 8, and the anchoring is achieved at a certain water depth.
[0025] As an optional implementation, Figure 3 is a schematic diagram of the structure of the pull rod assembly provided by an embodiment of the present invention, such as 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 spherical end of the ball head rod 21 is clamped in the clamping groove, 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 cover 5 through an explosive bolt 4.
[0026] like 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 two ends of the threaded rod 22 are respectively provided with thread grooves. One end of the ball head rod 21 is spherical and is clamped in the end clamping groove of the cylinder anchor 1. Figure 1 As shown, the slot is a spherical shape adapted thereto, and the other end of the ball head rod 21 is rod-shaped, with an external thread on the outside, which can be screwed into the thread groove at one end of the threaded rod 22. An external thread is provided on the outside of one end of the connecting rod 23, which can be screwed into the thread groove at the other end of the threaded rod 22, and the other end of the connecting rod 23 is connected to the end cover 5 through an explosive bolt 4.
[0027] As an optional implementation, two ends of the threaded rod 22 are left-handed threads and right-handed threads respectively.
[0028] The two ends of the threaded rod 22 are left-handed threads and right-handed threads respectively, and the two ends are connected to the ball head rod 21 and the connecting rod 23 respectively. When rotating, the ball head rod 21 and the connecting rod 23 can be tightened or loosened at the same time, thereby ensuring that when limiting the placement parts 7 of different lengths, the overall length of the pull rod assembly 2 can be adjusted to ensure that the end cover 5 can effectively limit the placement parts 7.
[0029] As an optional implementation, Figure 4 It is a schematic diagram of the cross-sectional structure of the end cover provided by an embodiment of the present invention, wherein the end cover 5 is provided with a protruding plate 51 on the side facing the barrel anchor 1; the protruding plate 51 is provided with a first bolt mounting hole; the end of the pull rod assembly 2 used for connecting with the end cover 5 is provided with a second bolt mounting hole, and the explosive bolt 4 is installed when the first bolt mounting hole is aligned with the second bolt mounting hole.
[0030] like Figure 4 As shown, the end cover 5 is provided with a protruding extension plate 51 on the side facing the barrel anchor 1, and the extension plate 51 is perpendicular to the end surface of the end cover 5. The extension plate 51 is also provided with a first bolt mounting hole, such as Figure 3 As shown, a second threaded mounting hole is further provided near the end of the tie rod assembly 2, and the first bolt mounting hole and the second bolt mounting hole are provided correspondingly, and the tie rod assembly 2 and the end cover 5 can be connected by installing an explosive bolt 4.
[0031] As an optional implementation, the explosive bolt 4 is a stepped cylindrical structure, and an axial threaded blind hole is provided on the end surface of the small diameter end for screwing in a screw to fix the explosive bolt 4.
[0032] The explosive bolt 4 is a stepped cylindrical structure, including an end with a smaller diameter and an end with a larger diameter, and is broken off from the step when it is broken off. Accordingly, the first threaded mounting hole and the second threaded mounting hole are also stepped. An axially arranged threaded blind hole is provided on the end face of the small diameter end of the explosive bolt 4, and during installation, the explosive bolt 4 can be screwed into the threaded blind hole from the outside by a screw, so that the pull rod assembly 2 is connected to the extension plate 51 as a whole.

[0035] As an optional implementation, the side wall of the first spring mounting hole is provided with a thread for screwing in a screw as a safety mechanism, and the screw is unscrewed before deployment.
[0036] The first spring installation hole is also provided with a thread, and when it is not necessary to deploy, the safety screw can be passed through the spring 3 and screwed into the first spring installation hole of the extension plate 51 to serve as a safety structure. Before deployment, the safety screw is screwed out to release the safety.
[0037] As an optional implementation, there are multiple tie rod assemblies 2 , and the multiple tie rod assemblies 2 are evenly distributed between the barrel anchor 1 and the end cover 5 .
[0038] In order to improve the reliability of the device as a whole, a plurality of tie rod assemblies 2 are provided, and the plurality of tie rod assemblies 2 are evenly arranged between the barrel anchor 1 and the end cover 5. Preferably, the number of the tie rod assemblies 2 may be 2, 3 or 4.
[0039] The above technical solution has the following beneficial effects: through mechanical design, a semi-enclosed design of deployment parts with different shapes in the barrel anchor is realized, which can shorten the travel of the deployment parts out of the barrel anchor during deployment; at the same time, the part exposed outside the barrel anchor can sense the environmental force information of 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, easy operation and low processing cost.
