[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] See Figures 1 to 16 The present invention provides a floating electromagnetic wave signal relay device, which includes a central processing unit 100, an antenna unit 200, and a floating unit 300.

[0043] The central processing unit 100 includes a first waterproof housing 101, a control circuit board 102 and a power supply assembly 103 disposed within the first waterproof housing 101, and the power supply assembly 103 is connected to the control circuit board 102.

[0044] Specifically, the first waterproof housing 101 has a multi-faceted conical structure, which effectively resists the impact of water waves and wind. Moreover, the first waterproof housing 101 is a sealed cavity with strong waterproof performance, which can effectively protect the internal components such as the control circuit board 102 and the power supply component 103.

[0045] More specifically, the first waterproof housing 101 includes a multi-faceted conical housing 1011 and a base plate 1012. The upper surface of the base plate 1012 is provided with a groove 1013 that matches the shape and size of the lower end of the housing 1011. The lower end of the housing 1011 is fitted into the groove 1013 to form a sealed cavity.

[0046] The main control circuit board 102 integrates a central processing unit and its peripheral circuits. The power supply assembly 103 may specifically include a battery box 1031, a lithium battery 1032, and a voltage stabilizer 1033, and is connected to a waterproof switch 1014, a waterproof power indicator 1015, and the main control circuit board 102. Controllable power supply to the main control circuit board 102 is achieved through the waterproof switch 1014. Figure 2 , 3 As shown in Figures 6 and 7; the waterproof switch 1014 and the waterproof power indicator 1015 are embedded in the surface of the first waterproof housing 101 (housing 1011), as shown in Figure 6. Figures 2 to 4 .

[0047] Furthermore, the surface of the first waterproof housing 101 (housing 1011) is provided with a battery cover 1016. The battery cover 1016 is connected to the housing 1011 via a rotating shaft, and a sealing ring is installed on the battery cover 1014, achieving waterproof sealing when the battery cover 1016 is closed. Similarly, the waterproof switch 1014, the waterproof power indicator 1015, the base plate 1012, and the housing 1011 are all sealed with sealing rings or adhesive bonding to achieve waterproof sealing. Figures 2 to 4 .

[0048] like Figure 2 , 3 As shown in Figures 5 and 15, the first waterproof housing 101 is also provided with a shielding cover 104. The control circuit board 102 is installed inside the shielding cover 104. The shielding cover 104 is made of metal and has multiple spaced anti-interference shielding walls 105 inside to isolate electromagnetic waves from the signal processing circuits of different frequency bands of the control circuit board 102.

[0049] In one feasible solution, the base plate 1012 of the first waterproof housing 101 is made of metal and connects with the shielding cover 104 to form a cavity, isolating the main control circuit board 102 located within this cavity from electromagnetic interference. Simultaneously, the base plate 1012 and the shielding cover 104 form a heat dissipation structure, dissipating the heat generated by the main control circuit board 102 outside the device. This structure, combined with the housing 1011, addresses multiple requirements including waterproof sealing, electromagnetic interference resistance, and heat dissipation. Furthermore, since the base plate 1012 serves as the supporting base of the entire device and is part of the waterproof structure, and its area is significantly larger than that of the main control circuit board 102, the heat dissipation effect is significantly enhanced. All of these structures are key to achieving the miniaturization, low cost, and low weight of this device.

[0050] like Figure 15 As shown, the antenna mechanism 200 includes a second waterproof housing 201 and an antenna assembly 202. The second waterproof housing 201 is sealed and connected to the first waterproof housing 101. The antenna assembly 202 is disposed inside the second waterproof housing 201 and is signal-connected to the control circuit board 102.

[0051] In one feasible solution, such as Figure 1 and 14The second waterproof housing 201 of the antenna mechanism 200 is cylindrical (e.g., cylindrical), and the antenna assembly 202 inside is also cylindrical and adapted to the cylindrical second waterproof housing 201. Specifically, the cylindrical second waterproof housing 201 includes a waterproof cover 203 and a base 204. The waterproof cover 203 is cylindrical with a closed upper end and an open lower end. The antenna assembly 202 is installed inside the waterproof cover 203 and connected to the control circuit board 102 via a cable 208. The base 204 is fitted together with the lower end of the waterproof cover 203, and the peripheral surface of the base 204 is provided with two or more positioning reinforcements 205 arranged in a ring array, preferably 3 to 6 positioning reinforcements 205. When the base 204 is assembled to the lower end of the waterproof cover 203, the positioning reinforcements 205 abut against the surface of the waterproof cover 203, providing guidance and constraint, which facilitates assembly operations and further enhances assembly stability.

[0052] As a preferred embodiment of the present invention, such as Figure 2 , 3 4, 13, 14, 15, the upper end of the first waterproof outer shell 101 (outer shell 1011) is provided with an installation interface 106, and the lower end of the antenna mechanism 200 is detachably assembled onto the installation interface 106. The lower end of the antenna mechanism 200 and the installation interface 106 are provided with multiple matching inclined surfaces. During assembly, rotation is performed, and a sealing ring is provided between them. Under the interaction of the respective inclined surfaces, the gap between the lower end of the antenna mechanism 200 and the installation interface 106 decreases. When the gap is at its minimum, the sealing ring is pressed to achieve a waterproof seal. Specifically, the installation interface 106 is provided with a rotating slot 107, the lower end of the second waterproof outer shell 201 of the antenna mechanism 200 is provided with an installation connector 206, and the peripheral surface of the installation connector 206 is provided with a locking block 207. That is, the bottom of the base 204 is provided with the installation connector 206 and the locking block 207. When assembling and using, the mounting connector 206 is fitted into the mounting interface 106, and the locking block 207 is engaged in the rotating slot 107 and screwed to the locking position of the rotating slot 107. The antenna mechanism 200 can be disassembled and stored, making it more convenient to carry and transport.

[0053] The mounting interface 106 has a storage space for the antenna mechanism 200 cable 208. When the antenna mechanism 200 is assembled with the central processing unit 100, the cable 208 can be coiled and rotated in the storage space. When the antenna mechanism 200 is removed, the cable 208 in the storage space can be pulled out so that the antenna mechanism 200 can be stored.

[0054] like Figure 1 , 7As shown in Figures 11, 12, and 16, the floating mechanism 300 includes three or more floating units 301, which are arranged in a circular array around the central processing unit 100. Each floating unit 301 is telescopically and / or foldably connected to the first waterproof outer shell 101 of the central processing unit 100. Specifically, the floating unit 301 includes a connecting rod 302 and a floating body 303. The connecting rod 302 includes a first connecting rod 304 and a second connecting rod 305. One end of the first connecting rod 304 is axially movable and fitted to the first waterproof outer shell 101 of the central processing unit 100, while the other end is rotatably connected to the second connecting rod 305. The second connecting rod 305 is fitted with the floating body 303. In use, pull out the first link 304, then flip up to open the second link 305, thus opening the floating unit 301; conversely, fold down the second link and retract the first link 304 inward to fold the floating unit 301. At this time, the floating unit 301 is located at the bottom of the central processing mechanism 100 (base plate 1012) and is hooked and locked by the limiting hook 1017 set on the base plate 1012. The operation is simple and convenient, and further improves the ease of storage and portability of this device.

[0055] More specifically, the peripheral surface of the first waterproof housing 101 (i.e., the base plate 1012) of the central processing unit 100 is provided with a connecting rod mounting structure, including a plug-in seat 108 and a locking buckle 109. The plug-in seat 108 is provided with a horizontal plug-in hole 110, and one end of the first connecting rod 304 is movably mounted in the horizontal plug-in hole 110. The locking buckle 109 is mounted on the plug-in seat 108 in a seesaw manner, and one end is provided with a spring 111. The two ends of the spring 111 are respectively connected to the locking buckle 109 and the plug-in seat 108. The other end of the locking buckle 109 extends to the front of the horizontal plug-in hole 110. The first connecting rod 304 is provided with a first locking position 306 and a second locking position 307. When the first connecting rod 304 is pushed inward to retract to the retracted state (fully retracted state), the other end of the locking buckle 109 is engaged in the first locking position 306. When the first connecting rod 304 is pulled outward to the working state (fully extended state), the other end of the locking buckle 109 is engaged in the second locking position 307. Moreover, during the inward and outward processes, the locking buckle 109 automatically engages in the first locking position 306 or the second locking position 307 under the action of the spring 111, making the operation simple, convenient, and quick. Of course, the first connecting rod 304 can also be provided with multiple second locking positions 307 to control each floating unit 301 and meet the usage requirements of different water surface environments.

[0056] The first connecting rod 304 and the second connecting rod 305 of the present invention are connected by a pivot structure, and at least one of the connecting rods 304 and 305 is provided with a rotation limiting part 317 at the connection end to limit the rotation range of the second connecting rod 305. In use, the second connecting rod 305 of each floating unit 301 can swing freely up and down with the rise and fall of the sea waves, maximizing the stability of the device and thus improving the reliability and safety of connection with underwater equipment.

[0057] Furthermore, the floating mechanism 300 of this application preferably employs three floating units 301, which are symmetrically distributed in a triangular pattern around the central processing mechanism 100. This satisfies the requirements for the floating support performance of the device while also achieving the goals of lightweighting and simplification.

[0058] For example Figure 1 , 7 As shown in Figures 11 and 12, the second connecting rod 305 is composed of a long rod and a short rod connected together, forming an L-shape. The end of the short rod is rotatably connected to the first connecting rod 304, and the floating body 303 is installed on the body of the long rod. By adopting the L-shaped second connecting rod 305, a storage space for the floating body 303 is formed between the second connecting rod 305 and the central processing mechanism 100 (base plate 1012) when the second connecting rod 305 is folded. The entire mechanism is in a compressed and folded state, which greatly reduces the space ratio of the floating mechanism 300 after it is folded, further improving the ease of storage and portability of this device.

[0059] In a preferred embodiment of the present invention, the floating body 303 is an inflatable airbag, which can be made of silicone or rubber. The upper end of the floating body 303 is provided with an upper sealing plate 306 and an upper support plate 307, which are airtightly connected to each other and airtightly connected to the upper outer surface and the upper inner surface of the inflatable airbag, respectively. The lower end of the inflatable airbag is provided with a lower sealing plate 308 and a lower support plate 309, which are airtightly connected to each other and airtightly connected to the lower outer surface and the lower inner surface of the inflatable airbag, respectively. Moreover, the upper sealing plate 306 is connected to a second connecting rod 305. The specific structure is as follows: The upper opening 311 and lower opening 312 of the inflatable airbag are provided with annular protrusions 313. After the upper sealing plate 306 is assembled and connected with the upper support plate 307, it clamps the annular protrusion 313 of the upper opening 311 of the inflatable airbag. After the lower sealing plate 308 is assembled and connected with the lower support plate 309, it clamps the annular protrusion 313 of the lower opening 312 of the inflatable airbag, achieving a waterproof seal. Figure 1 , 7 As shown in 8, 9, 10, and 12.

[0060] To further enhance the ease of storage and portability of this device, the inflatable airbag is an accordion-style airbag, with the thickness at the folded areas being less than the thickness at the non-folded areas. Specifically, the inflatable airbag has a multi-layered, compressible / stretchable shape, and each folded position is provided with a bending groove 314, the thickness at the bending groove 314 being less than the thickness at the non-bending area 315. Figure 1 , 7 As shown in 8, 9, 10, and 12.

[0061] Furthermore, an inflation / deflation switch 310 is provided between the lower sealing plate 308 and the lower support plate 309. The lower support plate 309 has an opening at its center, and the inflation / deflation switch 310 has an elastic sealing gasket embedded in it. The inflation / deflation switch 310 can slide within a limited range of the lower sealing plate 308 to open and close the opening at the center of the lower support plate 309. Simultaneously, two L-shaped protrusions 316 are provided on the lower sealing plate 308, allowing two fingers to grip the protrusions and pull the lower sealing plate 308, lower support plate 309, and the lower part of the inflatable airbag outwards, thereby inflating the airbag. Figure 10 As shown, this structure allows for one-handed inflation and deflation, which is very convenient.

[0062] As another preferred embodiment of the present invention, such as Figure 1 As shown, the floating electromagnetic wave signal relay device of the present invention also includes an underwater signal cable mechanism 400. To counteract the pulling force of surface waves on the underwater signal cable and improve the stability and safety of the underwater device and operator, the underwater signal cable mechanism 400 is detachably and adjustably connected to the central processing unit 100. Specifically, the underwater signal cable mechanism 400 includes a cable 401 and a cable adjusting component 402. The cable adjusting component 402 includes a telescopic connector 403 and a cable adjusting sleeve 404. One end of the telescopic connector 403 is connected to the first waterproof housing 101 of the central processing unit 100, and the other end is connected to the cable adjusting sleeve 404. The cable 401 is coiled, and one end of the cable 401 is connected to the control circuit board 102 inside the first waterproof housing 101 using a quick-connect structure (e.g., ...). Figure 16 One end of the cable 401 passes through the base plate 1012 and is connected to the terminal quick interface 1021 on the control circuit board 102 via the signal cable quick connector 4011. A waterproof sealing head 4012 is provided at the position where the cable 401 passes through the base plate 1012. The position where the cable 401 passes through the waterproof sealing head 4012 is bonded with waterproof sealant 4013. The waterproof sealing head 4012 is detachably assembled with the base plate 1012 by screws, and a sealing ring 4014 is provided between the waterproof sealing head 4012 and the base plate 1012. The other end is movably threaded through the cable adjustment sleeve 404.

[0063] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
