Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0027] For easier understanding, see Figures 1 to 8This embodiment provides an acoustic releaser with a dual release mechanism, including a pressure cabin 1. The pressure cabin 1 is composed of an upper cover 11, an external pressure cylinder 12 and a lower cover 13 from top to bottom. The pressure cabin 1 integrates electronic components such as a power supply, a controller, and a driving mechanism, has good sealing, and is suitable for high-pressure underwater environments. An acoustic transducer 2 is fixed above the upper cover 11. The acoustic transducer 2 is electrically connected to the controller. After receiving an external acoustic signal, the acoustic transducer 2 converts the acoustic signal into an electrical signal and transmits the electrical signal to the controller. The controller controls the release mechanism 3 to perform a release action according to the received electrical signal. Two groups of release mechanisms 3 are provided below the lower cover 13. Each group of release mechanisms 3 is electrically connected to the controller. The controller is used to drive the release mechanism 3 to achieve a release action, and a fault detection module is provided inside the controller, which can monitor the release status of the release mechanism 3 in real time. The release mechanism 3 includes a fixing member 31 and a locking member 32. The locking member 32 and the fixing member 31 are respectively connected to the left and right sides of the bottom of the lower cover 13. The rotating end 331 of the release member 33 is rotatably connected to the fixing member 31, and the locking end 332 of the release member 33 is locked and connected to the locking member 32. A chain 4 is connected between the two release members 33. The two ends of the chain 4 serve as two connecting ends 41 that respectively penetrate into the release members 33. Specifically, the hole diameter of the connecting end 41 of the chain 4 is larger than the outer diameter of the locking end 332 of the release member 33, that is, the chain 4 can penetrate into or out of the release member 33 from the locking end 332 of the release member 33 through the connecting end 41. When the release member 33 and the engaging member 32 are in the engaging state, the connecting end 41 of the chain 4 is between the rotating end 331 and the engaging end 332 of the release member 33, and the connecting end 41 of the chain 4 cannot pass through the engaging end 332 of the release member 33, that is, the chain 4 will not be separated from the release member 33; when the release member 33 and the engaging member 32 are released from the engaging state, the connecting end 41 of the chain 4 will pass through the engaging end 332 of the release member 33, that is, the chain 4 will be separated from the release member 33. A load is connected to the ring 5, and the ring 5 is inserted into the chain 4 through the connecting end 41 of the chain 4. Specifically, the inner diameter of the ring 5 is larger than the outer diameter of the connecting end 41 of the chain 4, that is, the ring 5 can pass into or out of the chain 4 from the connecting end 41 of the chain 4. When the release member 33 and the engaging member 32 are in the engaged state, the connecting end 41 of the chain 4 is between the rotating end 331 and the engaging end 332 of the release member 33, and the ring 5 cannot be detached from the connecting end 41 of the chain 4; when the release member 33 and the engaging member 32 are released from the engaged state, the connecting end 41 of the chain 4 will pass through the engaging end 332 of the release member 33, and the ring 5 can pass through the connecting end 41 of the chain 4, that is, the load connected to the ring 5 is released, and the releasing action is completed.
[0028] In the initial state, the release members 33 and the engaging members 32 in the two release mechanisms 3 are in an engaged state; when the acoustic transducer 2 receives a release signal, the release signal is transmitted to the controller, and the controller first transmits the release signal to the first release mechanism 3, drives the release member 33 and the engaging member 32 in the first release mechanism 3 to release the engaged state, so as to complete the opening action of the connecting end 41 on one side of the chain 4, thereby causing the ring 5 to detach from the opened connecting end 41 of the chain 4, and complete the release action of the ring 5 and the load; if the controller detects that the release member 33 and the engaging member 32 of the first release mechanism 3 have not been successfully released from the engaged state, the release signal is transmitted to the second release mechanism 3, drives the release member 33 and the engaging member 32 in the second release mechanism 3 to release the engaged state, so as to complete the opening action of the connecting end 41 on the other side of the chain 4, thereby causing the ring 5 to detach from the opened connecting end 41 of the chain 4, and complete the release action of the ring 5 and the load.
[0029] For easier understanding, see Figures 2 to 6 There are two fixing members 31 in each set of release mechanisms 3 and they are fixedly arranged under the lower cover 13 respectively. A connecting member 34 is fixedly connected between each set of fixing members 31. The rotating end 331 of the release member 33 is located between each set of fixing members 31 and is rotatably connected to the connecting member 34, so that the rotating end 331 of the release member 33 is evenly stressed, avoiding that one side of the rotating end 331 of the release member 33 is subjected to a large mechanical load, resulting in damage to the structure of the release member 33 and failure to achieve rotation.
[0030] For easier understanding, please continue to refer to Figures 2 to 6 There is one engaging member 32 in each set of release mechanisms 3, and the engaging member 32 is rotatably connected to the bottom wall of the lower cover 13 through a rotating bearing. A protrusion 321 is protruded outwardly in the horizontal direction at the lower part of the engaging member 32, and a horizontal notch 333 is correspondingly provided on the release member 33. The inner diameter of the notch 333 is larger than the outer diameter of the protrusion 321, that is, the protrusion 321 can pass through the inside of the notch 333. A driving component for driving the engaging member 32 to rotate is connected above the engaging member 32, and the driving component is electrically connected to the controller.
[0031] In the initial state, the release member 33 and the engaging member 32 are both in the engaging state, that is, the protrusion 321 of the engaging member 32 is engaged and connected to the inside of the notch 333 of the release member 33; when the controller receives the release signal, it transmits the release signal to the driving component of the release mechanism 3, and the driving component drives the engaging member 32 to rotate until the protrusion 321 of the engaging member 32 disengages from the notch 333 of the release member 33, and the driving component stops running. At this time, under the action of the gravity of the load, the connecting end 41 of the chain 4 exerts a downward force on the release member 33, driving the release member 33 to rotate around the connecting member 34 as the axis, that is, the release member 33 and the engaging member 32 are disengaged to complete the opening action of the connecting end 41 on one side of the chain 4, thereby making the ring 5 disengage from the opened connecting end 41 of the chain 4, completing the release action of the ring 5 and the load.
[0032] For easier understanding, see Figures 5 and 6 The driving assembly includes a motor seat 35, which is fixed inside the pressure-resistant cabin 1. A motor 36 is fixed on the motor seat 35. The engaging member 32 passes through the bottom wall of the lower cover 13 and extends to the inside of the pressure-resistant cabin 1. The engaging member 32 is connected to the output shaft of the motor 36 through a coupling for transmission. The motor 36 is electrically connected to the controller. When the controller receives the release signal, the release signal is transmitted to the motor 36 of the release mechanism 3. The motor 36 drives the engaging member 32 to rotate until the protrusion 321 of the engaging member 32 is disengaged from the notch 333 of the release member 33. The motor 36 stops running. At this time, under the gravity of the load, the connecting end 41 of the chain 4 generates a downward force on the release member 33, driving the release member 33 to rotate with the connecting member 34 as the axis, that is, the release member 33 and the engaging member 32 are released from the engaging state, so as to complete the opening action of the connecting end 41 on one side of the chain 4, thereby making the ring 5 disengage from the opened connecting end 41 of the chain 4, and completing the release action of the ring 5 and the load.
[0033] For easier understanding, see Figures 2 to 8 , a through slot 334 is provided at the engaging end 332 of the release member 33, and the inner diameter of the through slot 334 is larger than the outer diameter of the engaging member 32, that is, the engaging member 32 can pass through the through slot 334, that is, the engaging member 32 penetrates into the engaging end 332 of the release member 33 through the through slot 334. There are two protrusions 321 on the engaging member 32, which are arranged at 180° intervals in the circumferential direction of the engaging member 32, and there are two corresponding notches 333 on the release member 33, and both notches 333 are connected to the through slot 334. The engaging connection between the engaging member 32 and the release member 33 is realized through the cooperation of the protrusions 321 and the notches 333 on both sides, so that the engaging end 332 of the release member 33 is subjected to uniform force, and it is prevented that one side of the engaging end 332 of the release member 33 bears a large mechanical load, resulting in damage to the structure of the release member 33 and failure to realize the engaging action.
[0034] For easier understanding, see Figure 1A lifting lug 6 is fixedly installed on the top of the upper cover 11, which can be used for the acoustic releaser body to connect to a float or a lifting device, so that the staff can recover the acoustic releaser body after completing the working task.
[0035] The method of using the utility model is as follows: the staff first connects the load weight to the ring 5, and inserts the ring 5 into the chain 4, then inserts the two connecting ends 41 of the chain 4 into the two releasers respectively, and finally adjusts the release members 33 and the engaging members 32 of the two sets of release mechanisms 3 to the engaging state, so as to realize the connection between the load weight and the acoustic releaser body. The staff puts the acoustic releaser body with the load weight into the sea through relevant equipment. When the acoustic transducer 2 receives the release signal, it transmits the release signal to the controller. The controller first transmits the release signal to the motor 36 in the first release mechanism 3. The motor 36 drives the corresponding engaging member 32 to rotate until the two side protrusions 321 on the engaging member 32 are disengaged from the two side notches 333 of the release member 33, and the motor 36 stops running. At this time, under the action of the gravity of the load weight, the connecting end 41 of the chain 4 exerts a downward force on the release member 33, driving the release member 33 to rotate with the connecting member 34 as the axis, that is, the release member 33 and the engaging member 32 are released from the engaging state. To complete the opening action of the connection end 41 on one side of the chain 4, and then the ring 5 is separated from the already opened connection end 41 of the chain 4, and the release action of the ring 5 and the load is completed; if the controller detects that the release member 33 and the engaging member 32 of the first release mechanism 3 have not successfully released the engaging state, the release signal is transmitted to the motor 36 in the second release mechanism 3, and the motor 36 drives the corresponding engaging member 32 to rotate, that is, drives the release member 33 and the engaging member 32 in the second release mechanism 3 to release the engaging state, so as to complete the opening action of the connection end 41 on the other side of the chain 4, and then the ring 5 is separated from the already opened connection end 41 of the chain 4, and the release action of the ring 5 and the load is completed. After the release action is completed, the acoustic releaser body is recovered by the float or lifting equipment connected to the lifting lug 6.
[0036] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
