When the triad release is in operation, the release battery compartment 121 serves as a power source for the release 120, and supplies power to the release electronics compartment 122 and the underwater acoustic transponder 123.

Moreover, when the submerged buoy is subjected to load rejection, the elastic potential energy of the pressure spring 221 can be converted into kinetic energy for floating the buoy body 100, so that the floating of the buoy body 100 is accelerated; in addition, the elastic suspension type bottom-sitting submerged buoy device is more reliable in structure, smaller in size and stronger in salvage prevention.

In addition, the target body 100 further comprises functional equipment, wherein the functional equipment comprises a depth sensor 141, a Beidou positioning device 142, a high-frequency transmitting transducer 143, a low-frequency transmitting transducer 144, a hydrophone 145, a power amplifier cabin 146, an electronic cabin 147 and a battery cabin 148; the depth sensor 141, the power amplifier cabin 146, the electronic cabin 147 and the battery cabin 148 are fixed on the buoy body bottom plate 130, the Beidou positioning device 142, the high-frequency transmitting transducer 143, the low-frequency transmitting transducer 144 and the hydrophone 145 are fixed above the floating body 110, and the depth sensor 141, the Beidou positioning device 142, the high-frequency transmitting transducer 143, the low-frequency transmitting transducer 144 and the hydrophone 145 are respectively and electrically connected with the power amplifier cabin 146, the electronic cabin 147 and the battery cabin 148.

Fig. 4 is a schematic view of the elastic suspension assembly of the load rejection frame of the present invention. The compression spring 221, the compression spring guide post 222 and the split pin 223 jointly form the elastic supporting device 220 of the submerged buoy. The compression spring 221 is sleeved on the compression spring guide post 222, one end of the compression spring guide post 222 penetrates through the mounting hole of the coupling frame 211, and the compression spring guide post and the coupling frame 211 are assembled together through a split pin 223. The target body 100 is pressed on the polishing carrier 200 through the elastic supporting device, and the pressure spring 221 is compressed to a certain state under the action of the gravity of the target body 100.

The compression locking process of the elastic supporting device comprises the following steps: the wing nut 213 is rotated to further compress the compression spring 221 to a predetermined state (the distance between the target body and the bearing surface of the coupling frame 240 is 8mm to 12mm), and then the wing nut 213 is tightened to hold the compression spring 221 in the compressed state. The locking distance determines the elastic potential energy of the pressure spring 221, the structural stability of the submerged buoy can be improved, the connection rigidity is ensured, and if the spacing distance is too small, the buffering capacity of the pressure spring 221 is weakened when the submerged buoy is located on the seabed; if the spacing distance is too large, the locking force between the target body 100 and the throwing carrier 200 is insufficient, and the target body 100 is easy to shake.

The coupling frame 211 is a circular support frame, the load rejection bottom plate 215 is two circular flat plates which are arranged up and down with the circle center as an axis and have hollow middle parts, and the area of the upper circular flat plate is smaller than that of the lower circular flat plate. The load rejection bottom plate 215 can increase the contact pressure with the seabed when the submerged buoy is thrown into the seabed, and prevent the coupling frame 211 from sinking into seabed sludge. The compression spring 221, the threaded hook 212 and the release ring 124 are all arranged on the load rejection bottom plate 215, so that the compression spring 221 and the release ring 124 can be well prevented from being coated by sludge. The compression spring 221 is coated by the sludge for a certain time, the elastic potential energy of the compression spring 221 is weakened, and the compression spring 221 cannot recover and loses elasticity when the elastic potential energy is serious. The release ring 124 is in the sludge, which directly results in that the release ring 124 cannot fall off smoothly, the release fails, and the equipment cannot be recovered normally. Therefore, the structure of the load rejection bottom plate 215 greatly improves the reliability of the smooth recovery of the equipment.

As shown in fig. 5, the screw hook 212 penetrates through the center hole of the coupling frame 211, and the reverse side of the coupling frame is engaged with the wing nut 213, and the screw hook 212 is hooked on the release ring 124 to form the suspension device 210 as a sinking and setting member of the setting submersible buoy. And (3) rotating the butterfly nut 213, converting the rotation motion of the butterfly nut 213 into linear displacement of the threaded hook 212, further drawing the distance between the target body 100 and the polishing frame 200 under the transmission of force, further compressing the pressure spring 221, and locking the butterfly nut 213 when the distance between the target body bottom plate 130 and the coupling frame 211 is 8-12 mm.

The specific operation flow of the elastic suspension type bottom-sitting submerged buoy device comprises the following steps:

firstly, the label 100 is directly placed on the throwing carrier 200, the label base plate 130 is in direct contact with the pressure spring guide post 222 of the throwing carrier 200 to generate force, the pressure spring guide post 222 is stressed to generate displacement towards the free direction, the force is transmitted to the pressure spring 221 through the pressure spring guide post 222, and the pressure spring 221 is compressed under the action of gravity.

Secondly, the threaded hook 212 penetrates through the central hole of the coupling frame 211, the butterfly nut 213 is connected to the lower portion of the threaded hook 212, the upper portion of the threaded hook 212 is hooked on the release ring 124, and the butterfly nut 213 is rotated to enable the butterfly nut 213 to be locked when the distance between the target body bottom plate 130 and the coupling frame 211 is 8mm-12mm, so that the target body 100 can obtain enough floating potential energy and can quickly float when the release ring 124 is discarded.

Finally, the submerged buoy is thrown and the buoy body 100 floats to the surface by using the releaser 120 to discard the release ring 124. The buoy body 100 is used as the upper floating part of the submerged buoy, and the throwing carrier 200 is used as the lower sinking and bottom setting part of the submerged buoy. When the buoy body 100 is connected with the throwing carrier 200, the sinking force of the throwing carrier 200 in water is larger than the buoyancy force of the buoy body 100, the gravity borne by the submerged buoy is larger than the buoyancy force of the borne water, and the submerged buoy can freely sink to the seabed after being thrown. The release ring 124 can be discarded by controlling the underwater sound transponder 123 in the releaser 120, so that the mark body 100 and the throwing carrier 200 are separated, the constraint of the throwing carrier 200 is lost after separation, the buoyancy of the water borne by the mark body 100 is greater than the self gravity, and the mark body 100 floats to the water surface under the buoyancy of the water.

Finally, it should be noted that the above embodiments are only used for illustrating the patent technical solutions of the invention and are not limited. Although the present patent is described in detail with reference to the embodiments, it should be understood by those skilled in the art that the technical solutions of the present patent can be modified or substituted equally without departing from the spirit and the related scope of the present patent, which shall be covered by the claims of the present patent.
