Description

Technical Field

[0001] The utility model relates to the technical field of acoustic releasers, in particular to a mechanical acoustic releaser. Background Art

[0002] The acoustic releaser is a key device for the recovery of marine diving buoy systems. It is installed on an underwater platform or an underwater instrument and equipment mounting rack, with a counterweight connected to its lower part. When it receives the release command from the surface deck unit underwater, it performs the unhooking action, releases the counterweight, and then the entire platform or instrument equipment floats to the surface under the action of buoyancy, thereby realizing the recovery of underwater instruments or platforms and other systems.

[0003] For example, in the patent application with authorization announcement number CN216468386U and titled "An Acoustic Releaser", the acoustic releaser structure includes relatively parallel baffles provided on the bottom surface of the base, hooks are installed between the baffles through hook pins, and the hook pins are used for the rotation of the hooks; the top end of the hook contacts the sliding sleeve extending from the center hole.

[0004] Similar to the above application, the release mechanism of the mechanical acoustic releaser in the prior art mostly has two side plates forming a hook installation space, and then the hook is rotated and installed between the two side plates in conjunction with the rotating shaft, and the counterweight is released by rotating the hook to open. However, the hook installation space formed by the two side plates is an open structure. During actual use, the underwater environment is poor and it is easy for sand and gravel particles to be stuck between the two side plates under the action of surging water, thereby interfering with the rotation and opening stroke of the hook and affecting the stability of the release. Utility Model Content

[0005] The purpose of the present utility model is to overcome the problem in the prior art that the hook installation space composed of two side plates is an open structure. During actual use, the underwater environment is poor and it is easy for sand and gravel particles to be stuck between the two side plates under the action of surging water, thereby interfering with the rotation and opening stroke of the hook and affecting the stability of the release. A mechanical acoustic releaser is provided, which can completely block the peripheral openings of the two fixed side plates through the first lateral blocking plate and the second lateral blocking plate in cooperation with the fixed locking hook, thereby preventing sand and gravel particles in the water from entering between the high fixed side plates under the action of the water flow and interfering with the rotation adjustment of the fixed locking hook, thereby significantly improving the working stability of the release mechanism.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model discloses a mechanical acoustic releaser, comprising an acoustic releaser body, a release mechanism being fixed to the bottom of the acoustic releaser body.

[0008] The release mechanism includes two fixed side plates fixed in parallel, and the bottoms of the two fixed side plates are each provided with a connection opening;

[0009] A lock hook installation cavity is formed between the two fixed side plates, and a fixed lock hook is rotatably connected to the lock hook installation cavity by adjusting the rotating shaft. The fixed lock hook has two working states in its rotation stroke. In the first working state, the fixed lock hook closes the connecting opening, and in the second working state, the fixed lock hook opens the connecting opening.

[0010] The first and second lateral blocking plates are rotatably connected to the openings on both sides of the two fixed side plates through a rotating shaft, and a connecting head is fixed to the bottom of the two fixed side plates, and two elastic pull ropes are connected to the connecting head, and the two ends of the elastic pull ropes are respectively connected to the first and second lateral blocking plates, and the elastic force of the two elastic pull ropes is used to drive the bottom ends of the first and second lateral blocking plates to fit respectively on both sides of the fixed locking hook, wherein the thickness of the fixed locking hook is equal to the spacing between the two fixed side plates. When the bottom ends of the first and second lateral blocking plates are respectively fitted on both sides of the fixed locking hook, the first and second lateral blocking plates cooperate with the fixed locking hook to completely block the peripheral openings of the two fixed side plates, thereby preventing sand and gravel particles in the water from entering between the higher fixed side plates under the action of water flow, causing interference with the rotation adjustment of the fixed locking hook, and significantly improving the reliability of the release mechanism.

[0011] Preferably, the tail end of the fixed lock hook is connected to an adjustment arm, and the adjustment arm is provided with an adjustment slot along its length.

[0012] Preferably, a drive motor is installed inside the acoustic releaser body, and the output end of the drive motor is connected to an adjustment sleeve through a coupling transmission. An adjustment screw is spirally embedded in the adjustment sleeve, and the bottom end of the adjustment screw is rotatably connected to a cross bar, and the cross bar is slidably embedded in the adjustment slot. Specifically, when adjusting the fixed lock hook, the drive motor cooperates with the coupling to drive the adjustment sleeve to rotate and adjust. At this time, the adjustment sleeve drives the adjustment screw to move linearly. At this time, the cross bar at the bottom end of the adjustment screw cooperates with the adjustment slot to drive the fixed lock hook to rotate and adjust along the adjustment shaft to achieve opening of the fixed lock hook.

[0013] Preferably, a transducer is mounted on the top of the acoustic release body, and a battery pack and a controller are mounted inside the acoustic release body. The battery pack is electrically connected to the transducer, the controller, and the drive motor. The output end of the transducer is electrically connected to the controller, and the output end of the controller is electrically connected to the drive motor. During use, the battery pack is used to provide operating power for the transducer, the controller, and the drive motor. The transducer receives and transmits the acoustic signal to the controller, which analyzes and processes the signal and controls the operation of the drive motor, thereby securing the lock hook and opening it.

[0014] Preferably, a plurality of connecting screws are fixed in a circular arrangement on the top of the acoustic releaser body, an annular frame is fixed between the top ends of the plurality of connecting screws, and a hanger is welded on the annular frame.

[0015] Preferably, the adjusting shaft is rotatably installed between the two fixed side panels, the fixed lock hook is fixedly sleeved on the adjusting shaft, and an auxiliary unhooking mechanism is also provided on the outer side of the fixed side panel. The auxiliary unhooking mechanism is transmission-connected to the adjusting shaft. When the adjusting shaft rotates to drive the fixed lock hook to open, the adjusting shaft synchronously drives the auxiliary unhooking mechanism to push out the connecting cable embedded in the connecting opening.

[0016] Preferably, the auxiliary unhooking mechanism includes a disc seat and a push frame, the disc seat is rotatably arranged on the outer side of the fixed side plate and is coaxially connected to the adjustment shaft, and a convex portion is formed on the outer side of the disc seat;

[0018] Polish rods are fixed on both sides of the push frame. The two polish rods slide through the two limit seats, and support springs are sleeved on the polish rods. The elastic force of the support springs is used to drive the push frame to move upward.

[0019] Specifically, when the adjusting shaft rotates to drive the fixed lock hook to open, the adjusting shaft synchronously drives the disc seat to rotate. At this time, the convex part on the disc seat drives the push frame to move downward, so that the push frame pushes out the connecting cable embedded in the connecting opening, so that when the release mechanism in the mechanical acoustic releaser is opened, it can passively drive the auxiliary unhooking mechanism to push the connecting cable out of the connecting opening and separate it, thereby further improving the stability of the release mechanism.

[0020] Compared with the prior art, the utility model has the following beneficial effects: the mechanical acoustic releaser is connected to the first lateral blocking plate and the second lateral blocking plate through the rotating shaft on the openings on both sides of the two fixed side plates. When the fixed lock hook is locked again, the bottom ends of the first lateral blocking plate and the second lateral blocking plate are respectively attached to the two sides of the fixed lock hook. At this time, the first lateral blocking plate and the second lateral blocking plate cooperate with the fixed lock hook to achieve complete blocking of the peripheral side openings of the two fixed side plates, thereby preventing sand and gravel particles in the water from entering between the higher fixed side plates under the action of water flow, causing interference with the rotation adjustment of the fixed lock hook, and significantly improving the reliability of the release mechanism.

[0032] The openings on both sides of the two fixed side panels 41 are rotatably connected to the first side blocking plate 6 and the second side blocking plate 61 through a rotating shaft. A connector 62 is fixed to the bottom of the two fixed side panels 41, and two elastic pull ropes 63 are connected to the connector 62. The ends of the two elastic pull ropes 63 are respectively connected to the first side blocking plate 6 and the second side blocking plate 61, and the elastic force of the two elastic pull ropes 63 is used to drive the bottom ends of the first side blocking plate 6 and the second side blocking plate 61 to fit on both sides of the fixed lock hook 45.

[0033] The thickness of the fixed lock hook 45 is equal to the distance between the two fixed side plates 41. When the bottom ends of the first lateral blocking plate 6 and the second lateral blocking plate 61 are respectively attached to the two sides of the fixed lock hook 45, the first lateral blocking plate 6 and the second lateral blocking plate 61 cooperate with the fixed lock hook 45 to completely block the side openings of the two fixed side plates 41, thereby preventing sand and gravel particles in the water from entering between the higher fixed side plates 41 under the action of water flow, causing interference with the rotation adjustment of the fixed lock hook 45, and significantly improving the reliability of the release mechanism 4.

An auxiliary unhooking mechanism is also provided on the outer side of the fixed side plate 41. The auxiliary unhooking mechanism is transmission-connected with the adjusting shaft 44.
