Description

Technical Field

[0001] The invention relates to the technical field of acoustic releasers, in particular to an oil pipeline docking auxiliary device. Background Art

[0002] The acoustic releaser is a key device for the recovery of marine submersible buoy systems. The acoustic releaser mainly consists of three parts: a deck control unit, an acoustic transponder, and an actuator. The deck control unit is used to send acoustic control signals on board to realize remote operation of the releaser, receive confirmation signals returned by the releaser or transponder, and monitor the equipment status. The acoustic transponder communicates with the deck control unit, receives control signals and returns response signals to confirm the position and working status of the releaser. It is used as a relay station in deep-sea environments to enhance signal strength and stability. The actuator is used to execute the mechanical release of the locking device after receiving the trigger signal, so that the submersible buoy or other equipment floats to the sea surface.

[0003] Existing underwater acoustic releaser actuators generally achieve release by opening a closed connecting ring. However, when they are put into use, the connecting wire may be entangled in the connecting ring, resulting in the connecting wire being unable to be separated from the connecting ring even if the connecting ring is opened, affecting its stability in use. Utility Model Content

[0004] The purpose of the present utility model is to overcome the problem in the prior art that the existing underwater acoustic releaser actuator generally realizes release by opening a closed connecting ring. However, when it is put into use, the connecting line may be entangled in the connecting ring, resulting in that even if the connecting ring is opened, the connecting line cannot be separated from the connecting ring, affecting the stability of its use. An underwater acoustic releaser actuator is provided. When in use, the linkage component drives the linkage gear to rotate, and the linkage gear drives the arc rack to move. The arc rack drives the arc slider to slide in the arc guide rail, so that the gap at the bottom of the arc guide rail is opened, thereby opening the actuator and realizing release. When the connecting rope is entangled with the actuator, even if the actuator is opened, release cannot be realized. The linkage component can be controlled to continue to move downward to drive the connection mechanism to separate from the mounting seat to realize release, thereby realizing double release operation and improving its release stability.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 -Attached Figure 8 , further illustrating a specific implementation manner of an underwater acoustic releaser actuator of the utility model, overcoming the existing technology, the existing underwater acoustic releaser actuator, which generally realizes release by opening a closed connecting ring, but when it is put into use, the connecting line may be entangled in the connecting ring, resulting in timely opening of the connecting ring, and the connecting line cannot be separated from the connecting ring, affecting its stability in use. An underwater acoustic releaser actuator is provided, which is driven by a linkage component to rotate when in use, and the linkage gear drives the arc rack to move, and the arc rack drives the arc slider to slide in the arc guide rail, so that the gap at the bottom of the arc guide rail is opened, thereby opening the actuator and realizing release. When the connecting rope is entangled with the actuator, even if the actuator is opened, the release cannot be realized. The linkage component can be controlled to continue to move downward to drive the connection mechanism to separate from the mounting seat to realize release, thereby realizing double release operation and improving its release stability.

[0025] An underwater acoustic releaser actuator, comprising:

[0026] The device comprises a base 1, a connecting mechanism 3, and a mounting base 4. A threaded connection base 41 is fixed to the upper surface of the mounting base 4 for threaded connection to the bottom of the acoustic transponder. An actuator 2 is mounted below the base 1. The upper surface of the base 1 is detachably connected to the mounting base 4 via the connecting mechanism 3. The lower surface of the mounting base 4 is provided with a slot 42 for use with the connecting mechanism 3.

[0027] A linkage component 5 is provided on the connecting mechanism 3, and the linkage component 5 is transmission-connected to the actuator 2. The linkage component 5 has two downward working strokes. The first working stroke is when the linkage component 5 moves downward, the actuator 2 is driven to open, and the second working stroke is when the linkage component 5 continues to move downward, the driving connecting mechanism 3 is separated from the mounting seat 4.

[0028] The linkage assembly 5 includes a bar-shaped driving block 51, a connecting frame 54 is welded on the bar-shaped driving block 51, and a sliding seat 56 is welded to the other end of the connecting frame 54, the sliding seat 56 is slidably connected to the vertical slide groove 39 opened on the outer wall of the inverted concave seat 31, and a positioning shaft 57 is welded in the vertical slide groove 39, the sliding seat 56 is sleeved on the positioning shaft 57, and a second spring 58 is sleeved on the positioning shaft 57 below the sliding seat 56. A second wedge block 52 is welded to the top of one side wall of the bar-shaped driving block 51, and a driving rack 53 is welded on one side wall of the bar-shaped driving block 51 below the second wedge block 52, and the driving rack 53 is meshed with the linkage gear 27. An electric telescopic rod 55 is embedded in the mounting seat 4, and the bottom end of the electric telescopic rod 55 abuts against the second wedge block 52.

[0029] Specifically, when the underwater acoustic releaser actuator is used, the mounting base 4 is connected to the acoustic transponder through the threaded connection base 41 for use. When the acoustic transponder receives a control signal to control the actuator 2 to open for release, the electric telescopic rod 55 is first controlled to extend, pushing the second wedge block 52 to move downward, and the second wedge block 52 drives the entire bar drive block 51 to move downward, and the bar drive block 51 drives the drive rack 53 to move downward, and the drive rack 53 drives the linkage gear 27 to rotate, and the linkage gear 27 drives the arc rack 24 to move, and the arc rack 24 drives the arc slider 23 to slide in the arc guide rail 21, so that the notch at the bottom of the arc guide rail 21 is opened, thereby causing the actuator 2 to open and achieve release;

[0030] The actuator 2 includes an arcuate guide rail 21 and an arcuate slider 23. The inner wall of the arcuate guide rail 21 is provided with an arcuate groove 22 along its circumference. The arcuate slider 23 is slidably connected to the arcuate groove 22, and an arcuate rack 24 is embedded and installed on the outer wall of the arcuate slider 23. A rectangular hole 25 is provided on the outer wall of the arcuate guide rail 21. A concave seat 26 is welded on the arcuate guide rail 21 at the position of the rectangular hole 25. A linkage gear 27 is rotatably connected to the concave seat 26, and the linkage gear 27 is meshed with the arcuate rack 24.

[0031] Specifically, the working method of the actuator 2 is as follows: when in use, the linkage assembly 5 drives the linkage gear 27 to rotate, the linkage gear 27 drives the arc rack 24 to move, and the arc rack 24 drives the arc slider 23 to slide in the arc guide rail 21, so that the notch at the bottom of the arc guide rail 21 is opened, thereby opening the actuator 2 and achieving release;

[0032] It should be noted that the arc length of the bottom notch of the arc guide rail 21 is smaller than the arc length of the arc slider 23, so that when the arc slider 23 can completely close the bottom notch of the arc guide rail 21, and when the arc slider 23 slides to the position of the bottom notch of the arc guide rail 21, it will not separate from the arc guide rail 21.

[0033] The connecting mechanism 3 includes an inverted concave seat 31 welded on the base 1 and two symmetrically distributed inverted L-shaped frames 32. The two inverted L-shaped frames 32 are slidably connected in the inverted concave seat 31. A first wedge block 35 is welded on the outer wall of the bottom end of the vertical end of one of the inverted L-shaped frames 32. A first spring 38 is welded between the vertical ends of the two inverted L-shaped frames 32. A bar rack 36 is vertically welded on the vertical ends of the two inverted L-shaped frames 32, and a transmission gear 37 is provided between the two bar racks 36. The transmission gear 37 is meshed with the two bar racks 36. A rotating shaft is fixed on the transmission gear 37, and the rotating shaft is rotatably connected in the inverted concave seat 31.

[0034] Specifically, the working method of the connecting mechanism 3 is that, first, in the initial state, the two inverted L-shaped frames 32 are clamped in the clamping grooves 42 opened on the lower surface of the mounting seat 4 to achieve the connection between the connecting mechanism 3 and the mounting seat 4. In actual use, when the connecting rope is entangled with the actuator 2, even if the actuator 2 is opened, it cannot be released. The linkage assembly 5 can be controlled to continue to move downward to separate the connecting mechanism 3 from the mounting seat 4 and achieve release, thereby realizing a double release operation and improving its release stability.

[0035] The specific way of separating the connecting mechanism 3 from the mounting seat 4 is that the linkage assembly 5 continues to move downward, driving the second wedge block 52 to squeeze the first wedge block 35, thereby pushing one of the inverted L-shaped frames 32 to approach the center of the two inverted L-shaped frames 32, and at the same time driving the bar rack 36 to move, the bar rack 36 drives the transmission gear 37 to rotate, and the transmission gear 37 drives the bar rack 36 on the other inverted L-shaped frame 32 to move, thereby driving the other inverted L-shaped frame 32 to approach the center of the two inverted L-shaped frames 32, so that the two inverted L-shaped frames 32 approach each other, and at this time the first spring 38 contracts, thereby separating the two inverted L-shaped frames 32 from the card slot 42, completing the separation of the connecting mechanism 3 from the mounting seat 4.

[0036] A rectangular slider 34 is welded to the side wall of the inverted L-shaped frame 32 , and a horizontal slide groove 33 is provided on the inner wall of the inverted concave seat 31 . The rectangular slider 34 is slidably connected to the horizontal slide groove 33 .

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
