Description

Technical Field

[0001] This invention relates to the field of UUV equipment technology, and specifically to a zero-buoyancy deployment mechanism. Background Technology

[0002] After the load is released underwater via UUV, the mooring needs to be deployed. However, before the load is released, since the current main method is to use a ground-holding anchor structure, there is a problem of large negative buoyancy when the load is mounted on the platform. Large negative buoyancy may affect the stability of the buoy, especially under environmental loads such as wind, waves and currents. The buoy may experience large motion response, affecting the normal operation of the mounted load. Therefore, it is necessary to solve the problem of large negative buoyancy when the underwater mooring load is mounted on the platform. Summary of the Invention

[0003] In view of this, the present invention provides a zero-buoyancy deployment mechanism to achieve zero-buoyancy loading of underwater anchor loads.

[0004] The technical solution adopted in this invention is as follows:

[0005] A zero-buoyancy deployment mechanism includes a chuck, a float, a self-sinking anchor, an anchor connector, a limiting component, a separation rope, and an anchor rope.

[0006] The float is fixedly connected to the load, providing positive buoyancy to the load. The float is fixedly connected to the chuck via a spring plate, and its lower end is fixedly connected to the anchor connector. The spring plate is inserted into the load pin hole. The anchor connector encapsulates the top of the self-sinking anchor and limits its position via the limiting member. One end of the separation rope is fixed to the spring plate, and the other end is fixed to the limiting member. One end of the anchor rope is fixed to the anchor connector, and the other end is fixed to the self-sinking anchor.

[0007] Before the load is released, the inside of the self-sinking anchor is sealed and in a state of zero buoyancy. When the load is released, the chuck moves upward, pulls out the spring, the separation rope disengages, the limiting device releases the limit on the anchor connector, the anchor connector separates from the top of the self-sinking anchor, and water enters the self-sinking anchor until the anchor rope is straightened and fully deployed.

[0008] Furthermore, the float includes an upper connector and a float material. The upper connector is fixed to the top of the load by screws and provides an interface for connection with an external platform release device; the float material is fixed to the outer circumference of the load.

[0009] Furthermore, the self-sinking anchor includes an upper anchor cover, an anchor cylinder, a lower anchor cover, a piston pin, a piston, a sealing ring, and an anchor pin.

[0010] The piston is fixed to the top cover of the anchor by a piston pin. The two ends of the anchor cylinder are open. The top cover and the bottom cover of the anchor respectively close the two ends of the anchor cylinder and form a sealed cavity through the sealing ring. At the same time, the upper part of the top cover of the anchor is sleeved with the anchor connector and fixed by the anchor pin. The anchor connector is located on the outer circumference of the piston. The anchor pin is limited by the limiting member.

[0011] The piston pins and anchor pins are in pairs or more, and are evenly distributed.

[0012] Furthermore, the limiting component is a lifting ring, which is fitted onto the upper part of the anchor cover and abuts against the anchor pin;

[0013] The self-sinking anchor also includes a limiting post and a spring, with two or more limiting posts and springs in total. One end of the limiting post is fixed to the bottom surface of the anchor connector, and the other end passes through the lifting ring and is evenly distributed on the bottom surface of the anchor connector. The spring is fitted onto the limiting post, and both ends of the spring abut against the bottom surface of the anchor connector and the upper surface of the lifting ring, respectively. Before the load is released, the spring is in a compressed state under the action of the separation rope.

[0014] Furthermore, the end of the anchor pin is conical, and a conical limiting groove is provided on the outer periphery of the anchor connector;

[0015] The piston pin end is tapered, and a tapered limiting groove is provided on the outer periphery of the piston.

[0016] Beneficial effects:

[0017] 1. Before the load is released, the self-sinking anchor is sealed inside the water-filled structure, which is in a zero-buoyancy state, enabling the underwater anchor system to carry the load with zero buoyancy and meeting the requirements for underwater load anchor system deployment; secondly, when the load is released, the present invention can sink itself by water-filled structure, enabling reliable deployment of the anchor system.

[0018] 2. The water-intake self-sinking anchor of this invention utilizes water pressure to press a piston into the anchor cylinder to achieve water intake and self-sinking. The design is ingenious, and the structure is simple and easy to implement.

[0019] 3. The piston pin end of the present invention is conical, and a conical limiting groove is provided on the outer periphery of the piston to facilitate the piston pin to disengage from the piston under water pressure. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] This invention provides a zero-buoyancy deployment mechanism, including a chuck 1, a float 2, a water-inlet self-sinking anchor 3, an anchor connector 9, a limiting component, a separation rope 4, and an anchor rope 5;

[0026] like Figure 1 As shown, the float 2 is fixed to the load, providing positive buoyancy for the load. The float 2 is fixed to the chuck 1 via the spring plate 6, and its lower end is fixed to the anchor connector 9. The spring plate 6 is inserted into the load pin hole. The anchor connector 9 encapsulates the top of the self-sinking anchor 3 and limits it with a limiting member. One end of the separation rope 4 is fixed to the spring plate 6, and the other end is fixed to the limiting member, which is used to tighten the limiting member before the load is released. One end of the anchor rope 5 is fixed to the anchor connector 9, and the other end is fixed to the self-sinking anchor 3.

[0027] Before the load is released, the inside of the self-sinking anchor 3 is sealed and in a state of zero buoyancy. When the load is released, the chuck 1 moves upward, pulls out the spring 6, the separation rope 4 is released, the limiting device releases the limit on the anchor connector 9, the anchor connector 9 separates from the top of the self-sinking anchor 3, and the self-sinking anchor 3 sinks into the water until the anchor rope 5 is straightened and fully deployed.

[0028] Specifically, such as Figure 2 As shown, the float 2 includes an upper connector 7 and a float 8. The upper connector 7 is fixed to the top of the load by screws and provides an interface for connection with the external platform release device; the float 8 is fixed to the outer circumference of the load.

[0029] like Figure 3 As shown, the self-sinking anchor 3 includes an upper anchor cover 16, an anchor cylinder 18, a lower anchor cover 19, a piston pin 14, a piston 15, a sealing ring, an anchor pin 13, a limiting post 10, and a spring 11.

[0030] The piston 15 is fixed to the anchor cover 16 by the piston pin 14. The anchor cylinder 18 is open at both ends. The anchor cover 16 and the anchor cover 19 respectively close the two ends of the anchor cylinder 18 and form a sealed cavity through the sealing ring 17. At the same time, the upper part of the anchor cover 16 is sleeved with the anchor connector 9 and fixed by the anchor pin 13. The anchor connector 9 is located on the outer circumference of the piston 15. There are two or more piston pins 14 and anchor pins 13, which are evenly distributed.

[0031] The limiting component is a lifting ring 12, which is fitted onto the upper part of the anchor cover 16 and abuts against the anchor pin 13 to limit its movement. The number of limiting posts 10 and springs 11 is the same, both being two or more. One end of the limiting post 10 is fixed to the bottom surface of the anchor connector 9, and the other end passes through the lifting ring 12 to limit the circumferential movement of the lifting ring 12. The limiting posts 10 are evenly distributed on the bottom surface of the anchor connector 9. The springs 11 are fitted onto the limiting posts 10, and both ends of the springs 11 abut against the bottom surface of the anchor connector 9 and the upper surface of the lifting ring 12, respectively. Before the load is released, the springs 11 are in a compressed state under the action of the separating rope 4.

[0032] In this embodiment, three piston pins 14, three anchor pins 13, three limiting pins 10, and three springs 11 are used. The sealing ring is an O-ring 17.

[0033] Preferably, the end of the anchor pin 13 is conical, and the outer periphery of the anchor connector 9 is provided with a corresponding conical limiting groove.

[0034] The piston pin 14 has a tapered end, and the piston 15 has a corresponding tapered limiting groove on its outer periphery.

[0035] The specific work process of this organization is as follows:

[0036] When the load is loaded, the float 2 is installed on the load, the spring plate 6 is inserted into the load pin hole and the separation rope 4 is put on; the separation rope 4 tightens the lifting ring 12, at this time the anchor pin 13 and piston pin 14 limit the anchor cover 16 and piston 15 respectively, the anchor cover 16 is not separated from the anchor connector 9, and the piston 15 is not opened; the upper connector 7 is connected to the external platform release device, the upper end of the spring plate 6 is inserted into the chuck 1, and the loading is completed.

[0037] When the load is released, the chuck 1 moves upward, pulling out the spring 6. The end of the separating rope 4 connected to the spring 6 disengages, and the lifting ring 12 slides downward under the action of the spring 11. The anchor pin 13 is released from its limit, the anchor cover 16 separates from the anchor connector 9, and the piston 15, under the action of water pressure, releases the limit of the piston pin 14 and slides into the anchor cylinder 18. Water enters the anchor cylinder 18 until the anchor rope 5 between the anchor cover 16 and the anchor connector 9 is straightened, completing the deployment of the anchor system. The length of the anchor rope 5 is determined according to the specified anchor system sinking height.

[0038] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
