Description

The current release driving member can only release the buoy body alone, and the end cover is opened by the buoyancy of the buoy body itself, which has high requirements for static buoyancy. Once the static buoyancy requirement is high, the size of the device itself will become larger, resulting in an increase in the overall mass. And once the end cover gets stuck in this design, the buoy body may not be able to push open the end cover and float up without external force. Summary of the Invention

Detailed implementation manners

[0036] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention is provided in conjunction with the accompanying drawings.

[0037] As Figures 1 to 3 shown, the embodiment of the present application discloses an underwater buoy release device, including an enclosure 1, a bottom of the enclosure 1 is provided with an enclosure base 2, a top of the enclosure 1 is provided with an end cover 3, and an inner part of the enclosure 1 is provided with a buoy seat 8 for supporting a buoy 7, such that an upper space of the buoy seat 8 forms a buoy 7 placement cavity, and a lower space of the buoy seat 8 forms a drive installation cavity. A gear drive mechanism 34 is provided inside the enclosure 1;

[0038] The gear drive mechanism 34 includes a drive rod 41 and a first gear assembly 42 and a second gear assembly 43 mounted on the drive rod 41 for driving the end cover 3 to open and for locking or releasing the buoy 7. When the first gear assembly 42 and the second gear assembly 43 rotate synchronously, the end cover 3 opens and the buoy 7 is released;

[0039] A drive motor 5 for driving the drive rod 41 to rotate and a push motor 6 for pushing up the buoy 7 are provided inside the drive installation cavity.

[0040] Specifically, when the buoy 7 needs to be released, the drive motor 5 is started. The drive motor 5 drives the drive rod 41 to rotate. At this time, the first gear assembly 42 installed on the drive rod 41 starts to work, and the first gear assembly 42 drives the end cover 3 to rotate and open. At the same time, the second gear assembly 43 also starts to work. When the second gear assembly 43 rotates, it can unlock the buoy 7. With the synchronous rotation of the first gear assembly 42 and the second gear assembly 43, the end cover 3 is successfully opened, and the buoy 7 is also unlocked. After the end cover 3 is opened and the buoy 7 is unlocked, the push motor 6 is started, and the drive rod 41 of the push motor 6 extends, pushing the buoy 7 out upward from the enclosure 1. Since the buoy 7 has been unlocked and the end cover 3 has been opened, the buoy 7 can be smoothly pushed out of the enclosure 1 and float to the water surface.

[0041] For the underwater buoy release device and release method of the present invention, through the arrangement of the drive rod 41 and the first gear assembly 42 and the second gear assembly 43 located on the drive rod 41, the synchronous opening and release of the end cover 3 and the buoy 7 are realized. There is no need to rely on the buoyancy of the buoy 7 itself to open the end cover 3, reducing the requirement for static buoyancy, thereby reducing the overall size and mass of the device. At the same time, the steps of the buoy 7 release method of the present invention are simple and the operation is convenient, further improving the efficiency and reliability of the buoy 7 release.

[0042] In this embodiment, as Figure 4 and Figure 5 shown, the first gear assembly 42 includes a first driving gear 421 installed on the drive rod 41. A first driven gear 422 meshing with the first driving gear is arranged on one side of the first driving gear 421. It further includes an end cover rotating rod 423 connected to the first gear. The extending end of the end cover rotating rod 423 is fixedly connected to the end cover 3, and the connection position of the end cover rotating rod 423 and the end cover 3 is at a position away from the center point of the end cover 3.

[0043] Specifically, when the drive rod 41 rotates, the first driving gear 421 drives the first driven gear 422 to rotate. Since the end cover rotating rod 423 is connected to the first driven gear 422 and the connection position of the end cover rotating rod 423 and the end cover 3 is at a position away from the center point of the end cover 3, the rotation of the end cover rotating rod 423 will drive the end cover 3 to rotate and open around its center point.

[0044] This design method can ensure that the end cover 3 is evenly stressed during the rotation and opening process, avoiding jamming or damage. At the same time, since the end cover 3 is opened through a gear transmission mechanism, there is no need to rely on the buoyancy of the buoy 7 itself, thereby reducing the requirement for static buoyancy and reducing the overall size and mass of the device.

[0045] In this embodiment, as Figure 4 and Figure 5As shown, a gear box 424 is provided outside the first driving gear 421 and the first driven gear 422. The first driven gear 422 is of a first arc-shaped half-gear structure, and a limiting protrusion for limiting the second arc-shaped half-gear structure is provided in the gear box 424.

[0046] Specifically, the design of the gear box 424 not only protects the first driving gear 421 and the first driven gear 422 from external environmental interference, but also ensures the stability and accuracy of gear transmission. The setting of the limiting protrusion effectively limits the rotation range of the first driven gear 422, preventing misalignment or damage caused by excessive rotation. When the first driven gear 422 rotates to the position of the limiting protrusion, it will be blocked by the limiting protrusion and stop rotating. At this time, the end cover 3 also just opens to the predetermined position. This design method not only improves the accuracy and reliability of the opening of the end cover 3, but also avoids equipment damage or safety hazards caused by excessive opening of the end cover 3.

[0047] In this embodiment, as Figure 4 and Figure 5 shown, the second gear assembly 43 includes a second driving gear 431 mounted on the driving rod 41. A second driven gear 432 is provided on one side of the second driving gear 431. The second driven gear 432 includes a gear disk. A second arc-shaped half-gear structure meshing with the second driving gear 431 is provided on the outer circle of the gear disk, and a plurality of first wedge angle blocks 433 are spaced apart on the inner circle of the gear disk.

[0048] It further includes a buoy 7 located in the buoy placement cavity. The buoy 7 includes a pressure-resistant housing 701 and a pressure-resistant cover 702 mounted on the top of the pressure-resistant housing 701. A notch is provided on one side of the pressure-resistant cover 702. A connector 703 is provided in the pressure-resistant cover 702 and exposes from the notch. A locking wedge angle disk 704 is provided at the bottom of the pressure-resistant cover 702. A plurality of locking blocks 705 corresponding to the positions of the wedge angle blocks are provided on the locking wedge angle disk 704. A locking cavity is provided in the locking block 705, and a second wedge angle block 706 cooperating with the first wedge angle block 433 is provided in the locking cavity.

[0049] Specifically, as Figure 6 and Figure 7As shown, when the second driving gear 431 rotates, it drives the second driven gear 432 to rotate. Since the outer ring of the gear disk of the second driven gear 432 is provided with a second arc-shaped half-gear structure meshing with the second driving gear 431, the second driven gear 432 will rotate following the rotation of the second driving gear 431. Meanwhile, a plurality of first wedge angle blocks 433 arranged on the inner ring of the gear disk will interact with the locking blocks 705 on the locking wedge angle disk 704 of the buoy 7. In the initial state, the second wedge angle block 706 in the locking block 705 is clamped with the first wedge angle block 433, thereby locking the buoy 7 in the buoy placement cavity. However, when the second driven gear 432 rotates, the first wedge angle block 433 will withdraw from the locking cavity, thereby unlocking the buoy 7.

[0050] In the above structure, due to the settings of the first wedge angle block 433 and the second wedge angle block 706, the locking degree of the buoy 7 can be adjusted by controlling the relative positions of the first wedge angle block 433 and the second wedge angle block 706. At the same time, the applicable range of the buoy 7 is increased, and buoys 7 of different specifications can be restricted. Meanwhile, the setting of the arc-shaped half-gear drive enables the second driven gear 432 to have a larger stroke and greater rigidity, and it is safe and reliable during locking and releasing without jamming and dead points.

[0051] In this embodiment, as Figure 5 shown, upper peek pads 434 and lower peek pads 435 are respectively arranged on the upper side and the lower side of the second driven gear 432. The lower peek pad 435 is fixedly connected to the surrounding frame 1, and the upper peek pad 434 is connected to the lower peek pad 435 by bolts.

[0052] In this structure, the upper and lower sides of the second driven gear 432 are pressed by the upper peek pad 434 and the lower peek pad 435. This kind of drive abandons the design with a gear shaft in the middle of the gear, and can also achieve the use effect and is more reliable in actual use.

[0053] In this embodiment, as Figure 9 shown, the buoy seat 8 includes an eccentric disk 801. A plurality of guiding notches are arranged on the inner ring of the eccentric disk 801, and guiding bushings 802 are arranged in the guiding notches. It also includes a cable separation plate 803. The cable separation plate 803 is a special-shaped structure conforming to the eccentric disk 801. A U-shaped card interface 804 for clamping connection is arranged on the inner side of the cable separation plate 803. Fins 707 are arranged on the outer side of the pressure-resistant cover 702 and are in one-to-one correspondence with the plurality of guiding notches.

[0054] Specifically, during installation, the bottom of the buoy 7 passes through the center of the eccentric disk 801, the fins 707 of the buoy 7 are inserted into the guiding bushings 802, thereby ensuring the accuracy of the installation direction, and the connector 703 is snapped into the U-shaped card interface 804.

[0055] Specifically, by adopting the eccentric disc 801 with an eccentric design, we ensure sufficient installation space for the buoy 7 and avoid external interference during the release process, effectively reducing the risk of releasing the buoy 7. The guiding bushings 802 are evenly distributed around the eccentric disc 801 and made of PEEK material, which not only has reliable guiding performance but also has good lubrication effect and is convenient for replacement. The cable separation plate 803 adopts a special-shaped design matching the eccentric disc 801, making it possible to separate the connector 703 in the deep-sea environment. This design is both convenient and reliable, greatly simplifying deep-sea operations. The separation port adopts a U-shaped design, which can not only fix the position of the deep-sea connector 703 to prevent it from falling off due to shaking in water but also ensure the reliable separation of the connector 703. At the same time, the eccentric design of the eccentric disc 801 can leave space for the second gear assembly, increasing the center distance between the second driving gear and the second driven gear, reducing the transmission ratio, and increasing the torque, so as to unlock the buoy 7 more reliably.

[0056] In this embodiment, as Figure 8 shown, the pressure-resistant cover 702 is made of composite material, and the composite material is glass microspheres wrapped with fiberglass on the outside. The pressure-resistant cover 702 is in the shape of a hemispherical mushroom. The connecting part of the pressure-resistant cover 702 and the pressure-resistant housing 701 is a fine-thread structure, and the pressure-resistant housing 701 is made of titanium alloy TC4 material.

[0057] In the above structural design, the glass microspheres can provide significant buoyancy due to their low density, while the fiberglass is wrapped around the glass microspheres to play a protective role. The pressure-resistant cover 702 adopts a hemispherical mushroom-shaped design and uses fine threads at the connection to ensure reduced fluid resistance and reliable connection sealing. The pressure-resistant housing 701 is selected from titanium alloy TC4 material because of its excellent comprehensive mechanical properties. After the finite element static structure optimization and topology optimization of the outer shape of the main body, it is finally determined as a special columnar structure. It is supported by multiple layers of reinforcing ribs inside to ensure the strength of the structure. The whole structure adopts an integrated molding technology, which not only reduces the sealing surface but also reduces potential risks.

[0058] In this embodiment, a plurality of shoulders for installing and positioning each component in the frame 1 are arranged in the frame 1.

[0059] Specifically, the shoulder design in the frame 1 not only ensures the stability and accuracy of each component during the installation process but also improves the reliability and durability of the entire device. These shoulders are precisely machined and can fit perfectly with the components, avoiding equipment failures or safety hazards caused by improper installation.

[0060] The present invention also discloses a method for releasing the buoy 7 in water, including the above-mentioned buoy release device in water, and comprising the following steps:

[0061] S100: The driving motor 5 drives the driving rod 41 to rotate, the first gear assembly 42 drives the end cover 3 to rotate and open, and at the same time, the second gear assembly 43 rotates, and the buoy 7 is unlocked;

[0062] S200: The pushing motor 6 drives the rod 41 to extend, and pushes the buoy 7 upward out of the surrounding frame 1.

[0063] In the above method, through the synchronous drive of the first gear assembly 42 and the second gear assembly 43, the synchronous opening and release of the end cover 3 and the buoy 7 can be realized, without relying on the buoyancy of the buoy 7 itself to open the end cover 3, reducing the requirement for static buoyancy, thereby reducing the overall size and mass of the device, and at the same time ensuring the success rate of releasing the buoy 7.

[0064] In the specific embodiments described above, the purpose, technical solution and beneficial effects of the present invention are further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention.
