[0048] The technical solution of the invention will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are part of the embodiments of the invention, not all of them. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0049] Embodiment 1:

[0050] like Figure 1-Figure 5 As shown, an embodiment of the invention provides a buoy barrel, which includes a bow end cover, a midship barrel body and a stern end cover in sequence, and the midship barrel body includes a shell 1, a first connecting assembly 2 and a second connecting assembly 5;

[0051] The first connection assembly 2 includes a first adapter structure and a first docking plate 201 connected to each other;

[0052] The first adapter structure is embedded in one end of the housing 1 and is sealed and connected to the housing 1;

[0053] A first sealing structure is provided on one side of the first docking plate 201, and the first docking plate 201 is detachably sealedly connected to the bow end cover through the first sealing structure;

[0054] The second connection assembly 5 includes a second adapter structure and a second docking plate 501 connected to each other;

[0055] The second adapter structure is embedded in the other end of the housing 1 and is sealed and connected to the housing 1;

[0056] A second sealing structure is provided on one side of the second docking plate 501, and the second docking plate 501 is detachably sealedly connected to the stern end cover via the second sealing structure.

[0057] By setting up the first sealing structure and the second sealing structure, the sealing between the first docking plate 201 and the bow end cover and the sealing between the second docking plate 501 and the stern end cover can be enhanced. By respectively embedding the first adapter structure and the second adapter structure into the two ends of the shell 1 and sealingly connecting them to the shell 1, the sealing can be enhanced, and seawater is not easy to enter the buoy tube to cause corrosion of the detection equipment. In addition, due to the addition of the first adapter structure and the second adapter structure, the connection strength between the shell 1 and the bow end cover and the stern end cover is enhanced, thereby improving its overall pressure resistance effect. Even if it goes down to the seabed several thousand meters deep, the detection equipment is not easily crushed (damaged) by water pressure, and thus the detection equipment in the buoy tube does not need high pressure resistance and corrosion resistance, thereby reducing the cost of the detection equipment.

[0058] Moreover, compared with some buoy tubes that are integrally welded after the detection equipment is placed in them, this solution can be reused, thereby improving the reuse rate of the buoy tube.

[0059] According to one embodiment of the present invention, the shell 1 is a carbon fiber shell. The shell 1 made of carbon fiber can effectively withstand high pressure to protect the internal detection equipment. When the shell 1 is made of carbon fiber, even if the bow end cover and the stern end cover are made of different materials from the shell 1, the first adapter structure and the second adapter structure can also play a role in connection transition, strengthen the strength and sealing of the connection, and further improve the pressure resistance performance. Among them, the first connection component 2 and the second connection component 5 can be made of metal material, which has higher strength and better connection stability.

[0060] According to one embodiment of the present invention, a mounting ring plate is fixedly connected inside the first docking plate 201;

[0061] Along the circumference of the mounting ring plate, a plurality of antenna supports 7 for mounting antennas are fixedly connected to the mounting ring plate.

[0062] By providing the mounting ring plate, the antenna support 7 can be quickly installed in the midship cylinder, which is convenient for quickly installing the antenna and receiving signals.

[0063] According to one embodiment of the present invention, the first transition structure includes a first ring plate 202 and a first sealing ring 203;

[0064] The outer diameter of the first ring plate 202 is smaller than the outer diameter of the first docking plate 201. A first sealing ring groove is formed on the outer side of the first ring plate 202. The first sealing ring 203 is installed in the first sealing ring groove.

[0065] A first glue injection ring groove 204 is formed on one side of the first ring plate 202 away from the first docking plate 201;

[0066] Along the circumference of the first glue injection ring groove 204 , a plurality of first glue injection holes for injecting glue are spaced apart in the first glue injection ring groove 204 .

[0067] By setting a first sealing ring groove and installing a first sealing ring 203 in the first sealing ring groove, the first connecting component 2 and the shell 1 can be sealed once. By setting a first glue injection ring groove 204 and a plurality of first glue injection holes for glue injection opened on the first glue injection ring groove 204, after the first connecting component 2 and the shell 1 are sealed once, the first glue injection hole can be injected with potting agent through a syringe, so that the first glue injection ring groove 204 is filled with potting agent. When the potting agent is cured, a secondary seal is formed between it and the shell 1, thereby further improving its sealing and connection stability.

Therefore, it can protect the internal detection equipment, seawater will not enter the buoy tube, and the corrosion of the detection equipment by seawater is reduced.

[0079] The first rubber ring is inserted into the first stop 12, and when the first docking plate 201 and the third docking plate 301 are docked, the first rubber ring is squeezed and deformed to fill the gap between the first stop 12 and the third docking plate 301, thereby enhancing the sealing effect.

[0089] The second sealing structure includes a second stopper 14, a second limiting ring groove 15 and a plurality of second bolts;

[0090] The second stopper 14 is fixedly connected to one side of the stern adapter 6 close to the second docking plate 501;

[0091] A second limiting ring groove 15 adapted to the second stop 14 is formed on one side of the second docking plate 501 close to the stern adapter 6;

[0092] A second rubber ring is provided between the second stop 14 and the second limiting ring groove 15;

[0093] The second docking plate 501 and the stern adapter 6 are fixedly connected by a plurality of second bolts.

[0094] The second stop 14 and the second limiting ring groove 15 can improve the sealing performance between the second docking plate 501 and the stern adapter 6, thereby protecting the detector in the buoy tube from pressure influence and seawater erosion.

[0098] According to one embodiment of the present invention, a second drainage hole 10 is opened on the stern adapter 6, a second plug 11 is sealed in the second drainage hole 10, a fourth sealing ring is arranged between the second drainage hole 10 and the second plug 11, and the axis of the fourth sealing ring coincides with the axis of the second drainage hole 10.

[0099] The second drain hole 10 and the second plug 11 are provided with three types:

[0100] The first type is used at the stern adapter 6 close to the bow of the shell 1 , and its structure is the same as that of the first plug 9 .

Corresponding seawater electrolysis equipment can be installed in the buoy barrel to electrolyze seawater and generate energy, making the buoy barrel more practical.

[0104] Because the shell 1, the wave-transmitting radome 4 and the stern adapter 6 are made of different materials, the wave-transmitting radome 4 and the stern adapter 6 are directly connected to the shell 1, and the connection is easily damaged, and the connection is relatively weak and has poor pressure resistance. Therefore, by providing the first connecting component 2 and the second connecting component 5, the strength of the connection can be improved, and the sealing strength can be improved. It should be noted that the axis of the stern end cover, the axis of the midship cylinder and the axis of the bow end cover are all coincident.

[0105] Specific installation process:

[0109] The first connecting assembly 2 is taken out from the dry ice, and the radial first sealing ring 203 is quickly inserted into the first sealing ring groove, and quickly fitted with the port of the housing 1.

[0110] The second connecting component 5 also performs the sleeve operation on the other end of the housing 1. During the operation, the verticality of the end face of the second connecting component 5 and the axis of the housing 1 after being sleeved is ensured.

[0111] Step 3: After the buoy tube is fitted, no condensed water is generated on the surface of the bow end cover. At the third glue injection hole in the bow end cover, align the needle tube filled with the potting agent with the third glue injection hole and inject it into the third glue injection ring groove for sealing. After the internal potting agent is completely cured, the bow of the buoy tube is assembled;

[0112] Similarly, after the buoy device is sheathed, no condensed water is generated on the surface of the midship cylinder, and the same potting operation is performed at the first glue injection hole in the first connecting component 2 and the second glue injection hole in the second connecting component 5.

[0113] Step 4: After the internal potting agent is completely cured, use screws to fix the antenna support 7 in the mounting ring plate.

[0114] Step 5: The first drain hole 8 is then thread-sealed with a first plug 9 with an axial third sealing ring to complete the assembly of the buoy midship cylinder.

[0115] Step 6: The second drain hole 10 and the second plug 11 at the head of the stern adapter 6 have the same structure and the same assembly method as the first drain hole 8 and the first plug 9;

[0116] A second drain hole 10 and a second plug 11 are provided at the middle of the stern adapter 6. The second drain hole 10 is thread-sealed with a hexagon socket bolt with an axial third sealing ring, and then is evenly fastened in an annular direction with a plurality of first fastening bolts;

[0117] The second drainage hole 10 at the tail of the stern adapter 6 is sealed with a convex step plug with an axial fourth sealing ring, and then fastened circumferentially uniformly with a plurality of second fastening bolts;

[0118] The threaded holes at the lower end of the stern adapter 6 are respectively threadedly blocked with the same threaded positioning pins 16. The stern end cover of the buoy device is assembled.

[0119] Step seven: insert the first rubber ring into the first limiting ring groove 13 on the end face of the bow end cover of the buoy barrel, and pre-position and connect it with the upper port of the midship structure through the transition fit of the first stop 12, the first limiting ring groove 13 and the first rubber ring, and then fasten the first docking plate 201 and the third docking plate 301 through a circle of first bolts to realize the docking assembly of the bow end cover of the buoy barrel and the midship cylinder of the buoy device.

[0120] Similarly, a second rubber ring is inserted into the second limiting ring groove 15 on the end face of the midship cylinder of the buoy cylinder, and is pre-positioned and connected with the stern end cover port through the transition fit of the second stop 14, and then the second docking plate 501 and the stern adapter 6 are fastened by a circle of second bolts to realize the docking assembly of the midship cylinder of the buoy cylinder and the stern end cover of the buoy cylinder.
