Moreover, the optical fiber can only transmit the optical signal inside the optical fiber, and any signal outside the optical fiber is difficult to interfere with the signal transmission inside the optical fiber, so the transmission safety and reliability of the remote control signal can be further improved.
Meanwhile, compared with a cable and a twisted pair, the optical fiber is thinner and lighter, occupies smaller space after being coiled, and is easier to ensure the compactness and the compactness of the radio remote control receiving device and carry and install.

After the circuit board receives the release signal, the motor 331 is driven to rotate to drive the screw 333 to rotate; the circumferential limit structure prevents relative rotation between the float and the receptacle 31. Thus, as the screw 333 continues to rotate, the float finally unscrews from the nut 334 fixed to the float, unlocks the float, floats under the action of the positive buoyancy of the float, and finally completes the release.
3. The screw 333 and the nut 334 are rigidly connected by screwing and fixing through threads, so that the receiver 31 of the wireless remote control receiving device and the buoy can be better ensured to be relatively fixed, the occurrence of hanging and collision between the receiver and the buoy before use or release is avoided, and a better protection effect is achieved.

The pressure spring is in a compressed state all the time before the screw 333 is separated from the nut 334, and at the moment that the screw 333 is just separated from the nut 334, the pressure spring deforms and applies elastic force to the nut 334, so that the buoy and the receiver 31 can be separated more quickly and reliably, collision between the buoy and the receiver 31 can be avoided more effectively, and the buoy releasing process can be carried out more smoothly.
Meanwhile, the buoy can float upwards more quickly under the action of the spring force and the buoyancy force of the pressure spring, and the time required by subsequent radio remote control communication is shortened.
The circumferential limiting structure comprises a limiting pin 338 and a limiting hole, the surface of the buoy, which is closely opposite to the shell of the receiver 31, is fixedly provided with the limiting pin 338, and the surface of the shell of the receiver 31, which is closely opposite to the shell of the receiver 31, is provided with the limiting hole for inserting the limiting pin 338; the protruding length of the limit pin 338 is greater than the screwing length between the screw 333 and the nut 334.

Meanwhile, the water resistance received by the spherical buoy shell moving in water is smaller, and the buoy can obtain higher floating speed after the buoy is released, so that the preparation for receiving the wireless remote control signal can be carried out more quickly.
The buoy housing is provided with an upper housing 321 and a lower housing 324 which are divided in the middle in the height direction, and the upper housing 321 and the lower housing 324 are fixedly connected through flange sealing.

5. During the process of pulling out the cable around the spool 335 after the buoy is released: the inner side wall of the cable cover 325 can also play a role in preventing the cable from being quickly loosened and clamped; meanwhile, the inner side wall of the cable cover 325 can also play a role in limiting the vertical degree of the pulled-out cable, so that an overlarge transverse distance between the buoy and the radio remote control receiving device is avoided (the inclined angle of the pulled-out cable is large, so that the overlarge transverse distance between the buoy and the radio remote control receiving device is caused, and the overlarge transverse distance needs a longer cable, so that the weight is increased, the material is wasted, and the manufacturing cost is increased).
In practice, the inside lower end of the cylindrical structure of the cable cover 325 is chamfered. Therefore, the cable can be prevented from being broken by abrasion, and the effect of better protecting the cable is achieved.
Wherein the lower end of the cable cover 325 has a radially outwardly convex connection flange;

By adopting the assembly structure between the cable cover 325 and the buoy housing, the cable cover 325 can not only play a role in sealing the buoy housing; in addition, the cable cover 325 may be easier and more secure to assemble with the buoy housing; the cable cover 325 also makes full use of the interior space of the buoy housing, which helps to reduce the volume of the buoy, improve portability, and reduce the water resistance of the buoy floating up while ensuring the aesthetic property of the buoy.
In practice, the upper cable seal penetrates the cable cover 325 into the buoy and is connected to the antenna 322 via an optical module (not shown).
The outer upper end face of the cable cover 325 is located inside the buoy housing and forms a mounting face, and at least 2 batteries are fixedly mounted on the edge of the mounting face at equal intervals along the circumferential direction.

Wherein, the up end of spool 335 has along the outside convex connecting plate of footpath, the connecting plate pass through the screw with the interior top surface of cable cover 325 is fixed continuous.
After adopting above-mentioned cable cover 325 and spool 335 structure, can independently process production spool 335 and cable cover 325, it is fixed that the fast assembly of spool 335 on cable cover 325 can be realized through the screw afterwards, reduction production and assembly degree of difficulty.
Meanwhile, the self weight of the winding shaft 335 can be increased, and a counterweight structure in the middle of the bottom of the buoy is formed, so that the buoy floats up and floats on the water surface to keep a stable posture better, the antenna is ensured to be vertically upward, and an optimal signal receiving effect is obtained.

Wherein, the bobbin 335 is made of a solid material having a density greater than that of water.
After adopting above-mentioned structure, not only the focus position of adjusting the buoy is less than the floating center position, still makes the focus of buoy apart from the floating center position farther, can make the buoy can have more steady gesture in aqueous or the surface of water like this.
In practice, the bobbin 335 is made of steel material or copper material.
Wherein, a nut 334 is fixedly connected to the bottom of the bobbin 335, and the nut 334 is used for being in threaded connection with a screw 333 which can be driven to rotate on the receiver 31 of the wireless remote control receiving device and together form a structure which can be fixedly connected and released separately.
The fixing structure of the nut 334 is not only simpler in structure, but also easy to process and manufacture; it is also easy to achieve a separation of the connection and release with the receiver 31.
In addition, the weight of the bottom of the buoy can be increased, so that the distance between the gravity center and the floating center of the buoy is longer, the buoy can obtain better posture keeping efficacy, and the antenna can timely receive radio remote control signals after the buoy subsequently floats to the water surface.
The bobbin 335 is a cylindrical structure with an open lower end, a screw hole is formed in the side wall of the lower end of the bobbin 335 in a penetrating mode, a locking screw 339 is screwed in the screw hole, and the inner side section of the locking screw 339 is inserted into a slot in the outer side of the nut 334.

A pressure balance hole is formed through the side wall of the bobbin 335 above the nut 334.
In practice, the pressure balance hole formed in the spool 335 is not blocked by the coiled cable 336.
The provision of the pressure balancing holes ensures that the pressure within the tubular structure of the spool 335 is the same as the pressure outside, thereby reducing the torque required to unscrew the screw 333 from the nut 334 and helping to reduce the energy consumption required to release the float.
Wherein, the outside of the cable coiled on the winding shaft 335 is wrapped with a paraffin layer.
