Description

Technical Field

[0001] This invention belongs to the field of deep-sea prefabrication technology, specifically relating to a connection and separation device for a deep-sea stationary release platform and irregularly shaped components. Background Technology

[0002] To meet the needs of deployment and transportation, deep-sea pre-positioning systems typically connect all components to a deep-sea deployment platform as a whole. After deployment in the water and meeting preset conditions, the components separate and unfold sequentially. The connection and separation device, as the functional carrier for connecting and separating the components from the deep-sea deployment platform, plays a crucial role in the deployment, unfolding, and commissioning of underwater deep-sea pre-positioning systems.

[0003] Large, irregularly shaped components such as underwater landing vehicles require additional tooling for connection to the deep-sea deployment platform due to their irregular shape and heavy weight. This makes the connection, fixation, and rapid separation of these components relatively difficult in engineering implementation. Traditionally, to ensure the structural strength of these irregularly shaped components in all directions, multi-point connections are typically used to fix them around the circumference or in various directions. Separation of these components is primarily achieved through the simultaneous action of explosive devices or separation mechanisms. In practical engineering applications, because the simultaneous action of all explosive devices or separation mechanisms is required to complete the separation, the reliability requirements for these devices are extremely high. A failure at any node in the connection or separation mechanism will lead to the failure of the entire system's separation function, thus preventing the deep-sea pre-positioned system from completing its intended task. Summary of the Invention

[0004] The purpose of this invention is to provide a connection and separation device for a deep-sea stationary release platform and irregularly shaped components. This connection and separation device consists of an active separation unit, a passive separation unit, and a V-shaped connection support structure.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art, or in accordance with the product manual.

[0032] Example 1

[0033] Example 1 provides a connection and separation device for a deep-sea stationary release platform and irregularly shaped components, which can be found in [reference]. Figures 1-10 It consists of two sets of active separation units 1, two sets of passive separation units 2, and two sets of V-shaped connecting support frames 3. The active separation units 1 and passive separation units 2 are symmetrically arranged around the irregular component 5, and the V-shaped connecting support frames 3 work in conjunction with the passive separation units 2 to provide support for the irregular 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 dwelling and release platform 4 by a first screw 1-5, and the first connecting seat 1-1 is provided with a positioning groove. The release hook 1-2 is located on one side of the positioning groove, and its lower part is provided with a locking hole. The upper part is a cylinder with external threads, 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 retract and be pulled out from the locking hole when the pin puller 1-4 is working.

[0035] The surface of the first connecting seat 1-1 is provided with a threaded seat, the release hook 1-2 is provided between the positioning groove and the threaded seat, and the surface of the puller 1-4 is provided with an external thread that mates with the threaded seat, so that the puller 1-4 and the first connecting seat 1-1 are connected by a threaded engagement and screwed onto the first connecting seat 1-1.

[0036] The irregularly shaped component 5 is provided with a positioning boss that mates with the positioning groove. One side of the positioning boss is provided with a flange corresponding to the release hook 1-2. 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. The size of the through hole is adapted to the cylinder of the release hook 1-2. After the cylinder of the release hook 1-2 passes through the through hole, it 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 fixing block 2-5, and a screw 2-6. The second connecting seat 2-2 is fixed to the deep-sea dwelling and release platform 4 by a second screw 2-1, and the second connecting seat 2-2 has a groove with an opening on one side. The slider 2-3 is disposed in the groove and can move along the groove. The fixing block 2-5 is disposed on one side of the groove opening and is fixed to the second connecting seat 2-2 by a third screw 2-4. The fixing block 2-5 has a threaded through hole parallel to the groove. The screw 2-6 passes through the threaded through hole and abuts against the upper end of the slider 2-3, which can push the slider 2-3 to slide in the groove.

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

[0039] The assembly process is as follows:

[0040] 1. First, install the two sets of active separation units and the two sets of passive separation units onto the main platform using screws. The active separation units are arranged in a mirror image, with their positioning grooves located inside the axis of the main platform. The passive separation units are also arranged in a mirror image, with their sliders facing inside the axis of the main platform.

[0041] 2. Insert the positioning boss of the irregular 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 irregular component is assembled, tighten the release hook with nuts so that the positioning boss of the irregular component is in close contact with the platform connecting seat.

[0042] 3. Insert the groove of the V-shaped connecting support frame into the pin of the irregular 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, rotate the screw on the fixing block to make the slider press against the connecting support frame, thereby locking the V-shaped connecting support frame between the passive separation unit and the irregular component so that it cannot move.

[0043] The separation process is as follows:

[0044] 1. After the pin puller on the active separation unit is ignited, the pin retracts, releasing the restriction on the axial displacement of the release hook. The release hook moves downward along with the irregular component under its own gravity.

[0045] 2. As the irregularly shaped component moves downward, the distance between it and the passive separation unit increases, causing the V-shaped connecting support frame to release its displacement restriction. Under its own gravity, the V-shaped connecting support frame rotates around the pin of the irregularly shaped component. After rotating a certain angle, the V-shaped connecting support frame falls off from the pin of the irregularly shaped component.

[0046] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
