Description

Technical Field

[0001] The invention belongs to the technical field of deep-sea pre-positioning, and in particular relates to a device for connecting and separating a deep-sea resident release platform and a special-shaped component. Background Art

[0002] In order to meet the needs of deployment and transportation, the deep-sea pre-positioning system usually connects various components with the deep-sea resident release platform as a whole. After being placed in the water and meeting the preset conditions, the components are separated and deployed in sequence. The connection and separation device, as the carrier of the connection and separation function of each component and the deep-sea resident release platform, plays an important role in the deployment and service of underwater deep-sea pre-positioning.

[0003] Due to the irregularity of the external shape and heavy mass, large special-shaped components such as underwater nets require additional tooling to connect to the deep-sea resident release platform, making the connection, fixation and rapid separation of the special-shaped components relatively difficult in engineering implementation. In order to meet the support strength of special-shaped components in all directions, the traditional method is usually to fix the special-shaped components in a multi-point connection manner in the circumference or in all directions. The separation of special-shaped components is mainly achieved by the simultaneous action of explosive devices or separation mechanisms to separate the special-shaped components from the deep-sea resident release platform. In actual engineering applications, since the explosive devices or separation mechanisms need to act simultaneously to complete the separation of the special-shaped components from the deep-sea resident release platform, the reliability requirements of the explosive devices or separation mechanisms are extremely high. Failure in any node in the connection and separation device will lead to the failure of the overall separation function of the system, and then cause the deep-sea pre-set system to fail to complete the scheduled task.

[0032] Example 1

[0033] Example 1 provides a deep-sea resident release platform and a special-shaped component connection and separation device, which can be seen in Figure 1-Figure 10 , which is composed of 2 groups of active separation units 1, 2 groups of passive separation units 2 and 2 groups of V-shaped connection support frames 3. The active separation units 1 and the passive separation units 2 are symmetrically arranged around the special-shaped component 5, and the V-shaped connection support frame 3 is used in conjunction with the passive separation unit 2 to provide support for the special-shaped component 5.

[0034] The active separation unit 1 includes a first connecting seat 1-1, a release hook 1-2, and a pin puller 1-4; the first connecting seat 1-1 is fixed to the deep-sea resident release platform 4 by a first screw 1-5, and a positioning groove is provided on the first connecting seat 1-1; the release hook 1-2 is arranged on one side of the positioning groove, and a locking hole is opened at the lower part thereof, and the upper part is a cylinder with an external thread, which is adapted to the nut 1-3; the pin of the pin puller 1-4 extends into the locking hole, and the pin can be retracted and pulled out from the locking hole when the pin puller 1-4 is working.

[0035] A threaded seat is provided on the surface of the first connecting seat 1-1, and the release hook 1-2 is arranged between the positioning groove and the threaded seat. An external thread matching the threaded seat is provided on the surface of the pin puller 1-4, so that the pin puller 1-4 is connected to the first connecting seat 1-1 through threaded matching and is screwed on the first connecting seat 1-1.

[0036] The special-shaped component 5 is provided with a positioning boss matched with the positioning groove, and one side of the positioning boss is provided with a flange corresponding to the release hook 1-2, and the length of the flange from the end face of the positioning boss is greater than the depth of the positioning groove. A through hole is provided in the middle of the flange, and the size of the through hole is adapted to the cylinder of the release hook 1-2. The cylinder of the release hook 1-2 passes through the through hole and is locked with a nut 1-3.

[0037] The passive separation unit 2 includes a second connecting seat 2-2, a slider 2-3, a fixed block 2-5 and a screw 2-6; the second connecting seat 2-2 is fixed to the deep-sea resident release platform 4 by a second screw 2-1, and a slide groove with an opening on one side is provided on the second connecting seat 2-2; the slider 2-3 is arranged in the slide groove and can move along the slide groove; the fixed block 2-5 is arranged on one side of the slide groove opening and is fixed to the second connecting seat 2-2 by a third screw 2-4, and a threaded through hole parallel to the slide groove is provided on the fixed block 2-5; the screw 2-6 passes through the threaded through hole and is tightly pressed against the upper end of the slider 2-3, so as to push the slider 2-3 to slide in the slide groove.

[0038] The V-shaped connection support frame 3 is used to connect the passive separation unit 2 and the special-shaped component 5, and the two ends of the V-shaped connection support frame 3 are respectively provided with open grooves; the two sides of the special-shaped component 5 are respectively provided with protruding pins 6, and the pins 6 are engaged in the grooves of the V-shaped connection support frame 3; the tip of the V-shaped connection support frame 3 is an arc surface, which is tightly pressed against the lower end of the slider 2-3.

[0039] The assembly process is:

[0040] 1. First, install two sets of active separation units and two sets of passive separation units on the main platform respectively by screws. The active separation units are arranged in a mirror image, and the positioning grooves are all located on the inside of the main platform axis. The passive separation units are also arranged in a mirror image, and the sliders are all facing the inside of the main platform axis;

[0041] 2. Insert the positioning boss of the special-shaped component into the positioning groove of the first connecting seat. During assembly, the flange hole on the side of the positioning boss should pass through the cylinder of the release hook. After the special-shaped component is assembled in place, tighten the release hook with nuts respectively, so that the positioning boss of the special-shaped component is close to the platform connecting seat;

[0042] 3. Insert the groove of the opening of the V-shaped connecting support frame into the pin shaft of the special-shaped component, rotate the V-shaped connecting support frame so that the arc surface of its tip contacts the lower end of the slider of the passive separation unit, and rotate the screw on the fixed block to tighten the slider against the connecting support frame, thereby clamping the V-shaped connecting support frame between the passive separation unit and the special-shaped component and preventing it from moving.

[0043] The separation process is:

[0044] 1. After the pin puller on the active separation unit is ignited, the pin retracts, releasing the axial displacement restriction on the release hook, and the release hook moves downward together with the special-shaped component under the action of its own gravity;

[0045] 2. During the downward movement of the special-shaped component, the distance between the special-shaped component and the passive separation unit increases, so that the V-shaped connection support frame is released from the displacement restriction. The V-shaped connection support frame rotates around the pin of the special-shaped component under the action of its own gravity. After the V-shaped connection support frame rotates a certain angle, it falls off from the pin of the special-shaped component.

[0046] Although the present invention has been described in detail above by general description, specific implementation methods and experiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
