Description

Technical Field

[0001] This utility model relates to the field of buoy technology, specifically to a quick-assembly and disassembly structure for a wireless antenna of an underwater acoustic measurement buoy. Background Technology

[0002] As one of the three common mounting methods for underwater positioning and tracking systems, underwater acoustic buoy arrays are convenient to install at sea, highly mobile, and can operate independently of ships, making them widely used in the field of underwater acoustic communication and measurement. To achieve long-distance data communication between the underwater acoustic buoy and land-based command and control equipment, a high-altitude wireless antenna needs to be mounted on the top of the buoy. This results in a relatively large buoy length, making it difficult to store the buoy on offshore construction vessels or on land-based transport containers.

[0003] Currently, there are generally two methods. The first is to install the wireless antenna without disassembling it, using containers and ships with large storage space during construction. The second method usually uses screw connections, requiring tools for disassembly and assembly during construction. Because long-distance data transmission is required, wireless antennas are generally quite long (about 2 meters). Therefore, the first method would significantly increase the size of the container storing the underwater acoustic buoy, indirectly limiting the choice of construction vessels. The second method is the more common method, but it requires accompanying tools, and disassembly and assembly are not only time-consuming, but there is also a risk of losing screws during construction.

[0004] Therefore, a structure is needed that can quickly assemble and disassemble wireless antennas. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a quick-assembly and disassembly structure for a wireless antenna on an underwater acoustic buoy. It employs a mounting bracket to install the wireless antenna and utilizes a locking assembly for rapid fixation, ensuring antenna stability while effectively improving assembly and disassembly efficiency.

[0006] Specifically, this utility model provides a quick-assembly and disassembly structure for a wireless antenna on an underwater acoustic measurement buoy, comprising:

[0007] Mounting frame, with the antenna passing through the mounting frame in a direction parallel to the axis of the mounting frame, the mounting frame being used to connect the underwater acoustic measurement buoy;

[0008] An insulating sleeve is wrapped around the antenna and located at the overlapping part of the antenna and the mounting bracket. The insulating sleeve rotates as the antenna rotates.

[0009] A locking assembly, located on the mounting bracket, is used to lock the antenna.

[0010] Furthermore, the locking assembly includes:

[0011] Upper base, mounted on the mounting bracket;

[0012] The chuck is mounted on the upper base;

[0013] A tapered locking nut is fitted onto the antenna. After it is threadedly connected to the upper base, the claws retract to clamp the antenna.

[0014] Furthermore, the claw is a connector claw with an anti-loosening rubber ring on its upper inner side.

[0015] Furthermore, the mounting bracket includes:

[0016] The upper mounting plate, wherein the locking component is disposed on the upper mounting plate;

[0017] The lower mounting plate is used to connect the underwater acoustic measurement buoy, and a support pipe is provided between the upper and lower mounting plates.

[0018] Furthermore, the lower mounting plate is provided with a lower base, which is coaxial with the upper base, and the lower base is used to limit the antenna position.

[0019] Furthermore, the lower base has an inverted stepped hole inside, and a slot is provided at the top of the inverted stepped hole. The protrusion on the bottom side wall of the antenna enters the inverted stepped hole through the slot. When the antenna rotates to the point where the protrusion and the slot are misaligned, the antenna is prevented from detaching from the lower base.

[0020] Furthermore, the bottom of the insulating sleeve is provided with an arrow, and the surface of the lower base is provided with an alignment mark. When the antenna and the insulating sleeve are rotated until the arrow is aligned with the alignment mark, the antenna is released from its position.

[0021] The working principle of this utility model:

[0022] Pass the antenna through the upper and lower bases on the mounting bracket, aligning the arrow on the insulation with the alignment mark on the lower base. At this point, the lower protrusion of the antenna should align with the three slots on the lower base. After the antenna is inserted into the slots, rotate it to move the three protrusions circumferentially, thus limiting the antenna axially. Then, insert the tapered locking nut from the top of the antenna, gradually screwing it in using the mating threads of the tapered locking nut and the upper base. The tapered locking nut gradually compresses the connector claws, tightening them to clamp the antenna until the tapered locking nut and the upper base are in contact. Finally, install the assembled structure on top of the underwater acoustic buoy.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] (1) The present invention can effectively fix the antenna through the upper locking component and the lower base, and the connection of each part is simple and reliable, which can effectively improve the stability of antenna installation.

[0025] (2) After the initial installation, no tools are needed for subsequent installations of this utility model, and there are no small parts such as screws, which enables the rapid assembly and disassembly of the wireless antenna and avoids the risk of losing small parts such as screws.

[0026] (3) Most existing solutions do not insulate the wireless antenna. When in use, the outer shell is charged. In the corrosive marine environment, the outer shell is easily corroded. However, this utility model uses an insulating sleeve to wrap the lower part of the antenna, which can play a better role in protecting the wireless antenna from corrosion.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1-2 As shown, this embodiment provides a quick-assembly and disassembly structure for a wireless antenna of an underwater acoustic measuring buoy, including: a mounting bracket 2, an insulating sleeve 12, and a locking assembly 3. The mounting bracket 2 is used to install the antenna 1 and mount the antenna 1 on the top of the underwater acoustic measuring buoy 5. The insulating sleeve 12 wraps around the lower part of the antenna 1, together forming an insulated wireless antenna to prevent the antenna shell from becoming electrified and accelerating its corrosion. After insulation, it can play a role in corrosion protection. The locking assembly 3 is used to fix the antenna 1 and improve the ease of assembly and disassembly.

[0038] Specifically, the mounting bracket 2 includes an upper mounting plate 21 and a lower mounting plate 22. The upper mounting plate 21 and the lower mounting plate 22 are connected by four support tubes 23. The support tubes 23 are placed in four welding positioning holes of the lower mounting plate 22 for welding, and the upper end is fixed to the upper mounting plate 21 by bolts.

[0039] The locking assembly 3 is mounted on the upper mounting plate 21 and includes: an upper base 31, a claw 32, and a tapered locking nut 34. The upper base 31 is welded to the upper mounting plate 21 and has external and internal threads. The claw 32 is a plastic connector claw, such as... Figure 3 As shown, the lower external thread of the claw 32 mates with the internal thread of the upper base 31, enabling the assembly of the claw 32 and the upper base 31. A certain number of slots are evenly cut into the upper half of the claw 32. An anti-loosening rubber ring 33 is installed on the inner side of the upper half of the claw 32. The total length of the slots on the upper part of the claw 32 should be greater than 0.8 times the inner circumference of the original upper half of the claw minus the outer circumference of the anti-loosening rubber ring 33. This value is less than 1 and is determined according to the clamping force designed by the user. Generally, the smaller this value, the greater the clamping force. The claw 32 has a step inside, with the inner diameter of the step slightly larger than the maximum outer diameter of the antenna 1. This step serves to limit the downward movement of the anti-loosening rubber ring 33 during the clamping process.

[0040] The tapered locking nut 34 has a hexagonal nut structure machined on the outside for easy hand tightening. Both the internal thread tail and the external thread tail of the upper base 31 require thread relief grooves to ensure the tapered locking nut 34 can be tightened to the designated mounting end face of the upper base 31. The minimum inner diameter of the tapered locking nut 34 is slightly larger than the maximum outer diameter of the insulated antenna 1. The tail of the tapered locking nut 34 has a conical surface, which gradually clamps the chuck 32 and the anti-loosening rubber ring 33 during the tightening process. The conical surface has rounded corners at both ends to ensure smooth clamping.

[0041] The insulating sleeve 12 is installed on the part where the antenna 1 overlaps with the mounting bracket 2. It is an insulating rubber sleeve with an inner diameter slightly larger than the outer diameter of the bottom of the antenna 1 (including the protrusion 12). It has good heat shrinkability. The insulating sleeve 12 is fitted onto the bottom of the antenna 1 and covers the three protrusions 12 (screws) at its bottom. The insulating sleeve 12 is then heated by a hot air gun to make it form an integral part with the antenna 1, thus forming an insulated wireless antenna.

[0042] Furthermore, such as Figure 4-5 As shown, a lower base 24 is welded onto the lower mounting plate 22. The lower base 24 is coaxial with the upper base 31, and the antenna 1 passes through the upper base 31 and the lower base 24 from top to bottom. The lower base 24 has an inverted stepped hole 241 inside. The lower diameter of the inverted stepped hole 241 is slightly larger than the maximum diameter of the end of the protrusion 12 of the antenna 1, and the upper diameter of the inverted stepped hole 241 is slightly larger than the lower outer diameter of the antenna 1 (the outer diameter of the heat-shrinkable insulating sleeve 12). The upper part of the inverted stepped hole 241 is provided with three slots 242. The three protrusions 12 at the bottom of the antenna 1 are respectively in the three slots 242. The relative position of the protrusions 12 and the slots 242 can be adjusted by rotating the antenna. When the three protrusions 12 are aligned with the three slots 242, the antenna 1 can be moved out of the lower base 24 axially. Conversely, when the three protrusions 12 are misaligned with the three slots 242, the antenna 1 can be prevented from moving out of the lower base 24.

[0043] Furthermore, the bottom of the insulating sleeve 12 is provided with an arrow, and the surface of the lower base 24 is provided with a "cross target" alignment mark. When the arrow of the antenna 1 and the insulating sleeve 12 is aligned with the "cross target" alignment mark, the protrusion 12 of the antenna 1 can enter and exit the slot 242. When the antenna 1 is rotated to the point where the arrow is misaligned with the "cross target" alignment mark, the antenna 1 is limited.

[0044] Specifically, the initial installation process is as follows:

[0045] Install the necessary equipment (such as Beidou terminal equipment and GPS antenna) for the underwater acoustic measurement buoy 5 on the upper mounting plate 21.

[0046] Screw the claw 32 into the upper base 31 until the bottom of the claw 32 is tightly attached to the end face of the upper mounting plate 21, and then apply an appropriate preload to make the claw 32 and the upper base 31 firmly connected.

[0047] Install other equipment required for the underwater acoustic measurement buoy 5 (such as navigation lights and 5G data transmission antennas) on the lower mounting plate 22.

[0048] like Figure 6 As shown, press the brake pedal of the mobile cart 4 to keep it stationary, then place the underwater acoustic measuring buoy 5 on the mobile cart 4 and secure it with two telescopic straps 41.

[0049] Connect the connectors between the underwater acoustic measurement buoy 5 and the equipment on the lower mounting plate 22, such as navigation lights and 5G data transmission antennas. Pass all the connectors of the equipment on the upper mounting plate 21 through the support tube 23, and then connect the Beidou terminal equipment and GPS antenna.

[0050] Connect the underwater acoustic measuring buoy 5 and the mounting bracket 2 with screws.

[0051] Then install antenna 1 following these steps:

[0052] Insert the anti-loosening rubber ring 33 into the antenna 1 from the top.

[0053] Pass antenna 1 through claw 32 and connect it to the bottom connector of antenna 1.

[0054] Rotate antenna 1 so that the "arrow" mark on the insulating sleeve 12 is aligned with the "cross target" mark on the lower base 24. At this time, the three protrusions 12 of antenna 1 are aligned with the three slots 242 of the lower base 24. Rotate antenna 1 so that the "arrow" mark is misaligned with the "cross target" alignment mark. At this time, the three protrusions 11 of antenna 1 are misaligned with the three slots 241 of the lower base 24, thereby achieving the purpose of preventing the lower part of antenna 1 from falling out.

[0055] Push the anti-loosening rubber ring 33 into the stepped surface of the chuck 32. At this time, the anti-loosening rubber ring 33 is flush with the upper surface of the chuck 32.

[0056] Insert the conical locking nut 34 from the top of the antenna 1, and gradually screw it in using the mating threads of the conical locking nut 34 and the upper base 31 until the conical locking nut 34 and the upper base 31 are in contact.

[0057] During the screwing process, the conical surface of the conical locking nut 34 will gradually squeeze the upper jaw of the pawl 32 and the anti-loosening rubber ring 4, thereby squeezing the antenna 1 to achieve the purpose of tightening.

[0058] Release the brake pedal of the mobile trolley 4 and move it to the construction site to carry out the subsequent deployment of the underwater acoustic measurement buoy 5 at sea.

[0059] The process of removing antenna 1 is as follows:

[0060] Retrieve the underwater acoustic measuring buoy 5 and secure it to the mobile cart 4 with the telescopic strap 41. Unscrew the conical locking nut 34 and remove it from the top of the antenna 1. At this point, the pawl 32 is released, and the anti-loosening rubber ring 33 no longer compresses the antenna 1.

[0061] Rotate antenna 1 so that the "arrow" mark on the insulating sleeve 12 is aligned with the "cross target" mark on the lower base 24, pull out antenna 1, and disconnect antenna 1 from the underwater acoustic measurement buoy 5.

[0062] Screw the tapered locking nut 34 into the upper base 31 and apply a certain preload.

[0063] Push the mobile cart 4 back and store the antenna 1 for the next test.

[0064] For the second and subsequent installations, first unscrew the conical locking nut 34, and then follow the antenna installation and disassembly steps described above.

[0065] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
