DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that specific embodiments described herein are only used to illustrate the present disclosure and not intended to limit the present disclosure.

Referring to FIG. 1 to FIG. 16, a water surface floating type electromagnetic wave signal relay device according to the present disclosure includes a central processing mechanism 100, an antenna mechanism 200, and a floating mechanism 300.

The central processing mechanism 100 includes a first waterproof housing 101, a control circuit board 102 and a power supply assembly 103, where the control circuit board 102 and the power supply assembly 103 are arranged inside the first waterproof housing 101, and the power supply assembly 103 is connected to the control circuit board 102.

Specifically, the first waterproof housing 101 has a polyhedral cone structure, which is effectively resistant to the impact of water waves and wind. Moreover, the first waterproof housing 101 is a sealed cavity with strong waterproof performance, and thus can effectively protect its internal control circuit board 102, power supply assembly 103 and other components.

More specifically, the first waterproof housing 101 includes a housing 1011 and a bottom plate 1012, where the housing 1011 is a polyhedral cone, a groove 1013 is formed in an upper surface of the bottom plate 1012, the groove 1013 matches the shape and size of a lower end of the housing 1011, and the lower end of the housing 1011 is fitted in the groove 1013 to form the sealed cavity.

The main control circuit board 102 is integrated with 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, where the battery box 1031, the lithium battery 1032, and the voltage stabilizer 1033 are in signal connection with a waterproof switch 1014, a waterproof power display 1015, and the main control circuit board 102, and the main control circuit board 102 is supplied with controllable power through the waterproof switch 1014, as shown in FIG. 2, FIG. 3, and FIG. 6. The waterproof switch 1014 and the waterproof power display 1015 are embedded in the surface of the first waterproof housing 101 (housing 1011), as shown in FIG. 2 to FIG. 4.

In addition, 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 by means of a rotating shaft, and a sealing ring is mounted on the battery cover 1014 to achieve sealing for waterproofing after the battery cover 1016 is closed. Similarly, the waterproof switch 1014, the waterproof power display 1015, the bottom plate 1012 and the housing 1011 are all sealed for waterproofing by using sealing rings or bonding methods, as shown in FIG. 2 to FIG. 4.

As shown in FIG. 2, FIG. 3, FIG. 5, and FIG. 15, the first waterproof housing 101 is also provided with a shielding case 104, the control circuit board 102 is installed inside the shielding case 104, the shielding case 104 is made of metal, and the shielding case 104 is internally provided with a plurality of anti-interference shielding walls 105 arranged at intervals for conducting electromagnetic wave isolation on different frequency band signal processing circuits of the control circuit board 102.

In an implementable solution, the bottom plate 1012 of the first waterproof housing 101 is made of metal and is connected to the shielding case 104 to form a cavity, so as to isolate the external electromagnetic interference to the main control circuit board 102 located in the cavity. Furthermore, the bottom plate 1012 and the shielding case 104 form a heat dissipation structure to dissipate the heat generated by the main control circuit board 102 to the outside of the device. The combination of this structure with the housing 1011 takes into account multiple requirements such as waterproof sealing, anti-electromagnetic interference, and heat dissipation; and since the bottom plate 1012 is the supporting bottom plate of the entire device and is part of the waterproof structure, and the area of the bottom plate 1012 is much larger than that of the main control circuit board 102, the heat dissipation effect is significantly enhanced. The above structure are the key to realize the miniaturization, low cost and low weight of the device.
