The sealing performance of the main bin is ensured through the structure, and stable connection with the floating body 2 is ensured.
The antenna rod 1 penetrates through the floating body 2, and a satellite antenna 9 is arranged in the antenna rod 1; the upper end of the main body pressure-resistant cabin is in threaded connection with an antenna cabin, and the lower end of the main body pressure-resistant cabin is in threaded connection with an end cover 3 of the main body pressure-resistant cabin so as to facilitate quick connection; the main bin, the antenna rod 1 and the antenna bin are processed by PEEK materials.
The base bin is arranged below the main bin and detachably connected with the main bin through the release mechanism, and a base circuit board 11, a base coil 13, a base antenna 14 and a watertight socket 12 are arranged in the base bin; the base circuit board 11 is electrically connected to the base coil 13, the base antenna 14, and the watertight socket 12, respectively.
The base circuit board comprises an underwater communication circuit and a charging transmitting circuit. The underwater communication circuit is electrically connected with the base antenna and is used for underwater wireless communication. The charging transmitting circuit is electrically connected with the base coil and is used for transmitting electric energy transmitted by the watertight socket through the base coil after modulation and inversion. The release mechanism is electrically connected with the watertight socket and comprises, but is not limited to, an electromagnet and a fuse. The watertight socket 12 energizes the base circuit board 11 through an external control unit.
The base cabin comprises a base pressure-resistant cabin end cover 5 and a base pressure-resistant cabin cylinder body 10; an inner groove is formed in the upper end of the base pressure-resistant cabin end cover 5, and the main cabin is embedded in the inner groove; the base pressure-resistant cabin barrel 10 is arranged below the base pressure-resistant cabin end cover 5, and an inner cavity for installing the base circuit board 11 is formed between the base pressure-resistant cabin end cover 5 and the base pressure-resistant cabin barrel 10; the base antenna 14 and the base coil 13 are sealed in the base pressure-resistant cabin end cover 5 made of epoxy resin to form a unitary structure; the upper end of the main coil is extended to the positions of the main body circuit board 6 and the main body coil 7 in the main bin, and the lower end of the main coil is electrically connected with the base circuit board 11.
The release mechanism comprises an electromagnet 15 and a magnetic conduction sucker; the magnetic conduction sucker is arranged at the bottom of the main bin; the electromagnet 15 is sealed in the base pressure-resistant cabin end cover 5 at the position corresponding to the magnetic conduction sucker. Wherein the electromagnet 15 is a power-off type electromagnet.
The spring is arranged between the main bin and the base bin, and a protective sleeve is arranged on the base bin outside the spring. The protection sleeve mainly plays a role in protecting the spring, reduces the influence of the complex environment under the sea on the spring, and plays a role in boosting when the main bin and the base bin are separated.
The working principle is as follows:
after reaching the preset time, the control unit charges the battery 8 through the watertight socket 12 and the base circuit board 11 by utilizing electromagnetic induction between the base coil 13 and the main body coil 7; when external charging is detected, the main body circuit board 6 wakes up from a standby state and starts monitoring the voltage of the battery 8, and after charging is completed (the voltage of the battery rises to a set value), the main body circuit board 6 sends a charging completion signal to the control unit and starts receiving the observation data of the underwater platform transmitted through the base antenna 14; after the data is received and checked, the data is stored in an internal memory; at this time, the control unit sends out a release control signal, the electromagnet 15 is electrified, and because the electromagnet 15 is a power-off type electromagnet, the magnetic force between the electromagnet 15 and the magnetic conduction sucker is lost, so that the separation of the main bin and the base bin is realized under the boosting action of the spring. The main bin rises to the sea surface under the buoyancy force. The main circuit board 6 utilizes the satellite antenna 9 to search satellite signals at fixed time, and once the satellite signals are found, satellite data transmission is started immediately, so that the return of observation data is realized.
Example 2, as shown in fig. 2:
Because the main bin and the base bin are connected in a separable way, and a certain gap exists between the main bin and the base bin, when the equipment is under water, seawater can infiltrate into the clamping groove 16 to fully fill the inside of the clamping groove with seawater, at the moment, the base circuit board 11 sends out a control signal, and the fusible link 21 and the fusing electrode 18 realize a loop under the conduction action of the seawater in the clamping groove 16, so that electrochemical reaction is generated to disconnect the fusible link 21, and the separation of the main bin and the base bin is realized.
Considering the connection mode between the main bin and the base bin and the fact that the complex condition under the sea can lead to continuous rotation deviation between the main bin and the base bin, the situation that the fuse 21 is broken naturally under a long-term state can be caused, and therefore, the bottom cross section of the corresponding limiting block 17 is smaller than the bottom cross section of the clamping groove 16 through the arrangement of the corresponding limiting block 17 at the bottom of the main bin. If a cuboid structure is adopted, the length of the limiting block 17 is consistent with the length of the clamping groove 16, and the width of the limiting block 17 is smaller than the width of the clamping groove 16, so that a certain reserved space is ensured, and normal reaction of the fuse 21 and the fusing electrode 18 after being electrified and seawater is ensured.
Considering that there is still a certain uncontrollable factor of the seawater existing in the clamping groove 16 by considering the gap between the main bin and the base bin, the through hole 20 is started at one side of the base pressure-resistant cabin end cover 5, so that the clamping groove 16 is directly communicated with the outside through the through hole 20. And a corresponding fuse screw 19 is arranged at one side of the through hole 20, so that the fuse 21 is sequentially arranged between the base circuit board 11, the fuse screw 19, the through hole 20 and the bottom end of the main bin. Through the connecting structure, after the fuse wire 21 between the fusing screw 19 and the main bin is fused, only the fuse wire 21 in the interval needs to be replaced, and the base bin does not need to be frequently disassembled, so that the risk of reducing the sealing performance of the base bin is reduced; and also facilitates tightening of the fuse 21 between the fuse screw 19 and the main cartridge during assembly.
The working principle is as follows:
the control unit sends out control signals, and the fuse 21 and the fusing electrode 18 are electrified and then subjected to electrochemical reaction with seawater, so that the fuse 21 between the fusing screw 19 and the bottom end of the main bin is fused, and the separation of the main bin and the base bin is realized.
Although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
