Background

The submerged buoy can realize long-term continuous measurement of marine elements at the laying point of the submerged buoy, and is one of important devices capable of carrying out fixed-point continuous observation on the marine elements. For example, patent document CN201220748198.8 discloses a basic structure of 3500 m submerged buoy: "is formed by connecting the following components in series: the device comprises a main floating body support, 50-meter Kevlar ropes, a first floating ball group, a first 1000-meter Kevlar rope, a second floating ball group, a second 1000-meter Kevlar rope, a third floating ball group, a third 1000-meter Kevlar rope, a fourth floating ball group, a releaser group and an anchor system. The releaser group is close to the anchor system, and the minimum pressure resistance value of the release group in the 3500 m submerged buoy needs 3500 m water depth pressure resistance. The 3500 m submerged buoy is used for 1 ADCPs, is erected on a main floating body bracket and upwards probes the ocean current profile within the range of 500 m from the distance to the sea level. 25-30 floating balls and 4-6 releasers are used for the 3500 m submerged buoy. The "core device of the subsurface buoy is an Acoustic Doppler flow profiler (ADCP). ADCP is currently widely used for flow field structure survey, flow velocity and flow rate test, and the like of oceans and estuaries. The ADCP actively sends out sound waves, so that the ADCP is easily exposed, damaged and lost.

Some marine observation submerged buoy is provided with a real-time satellite communication buoy or a timing satellite communication buoy, the underwater working state and observation data of the submerged buoy can be transmitted to a shore station through the satellite communication buoy, and the satellite communication buoy floating on the water surface for a long time is easily damaged by passing ships and causes the submerged buoy underwater observation unit to be influenced, so that the marine observation submerged buoy has great defects. The current radio orientation positioning technology is quite mature, and the position of a submerged buoy is easily exposed during satellite communication.

In addition to the fact that communication is easily exposed and damaged to cause the submerged buoy to be lost, the submerged buoy can be lost due to various reasons such as acoustic communication faults of an acoustic releaser, broken shackle corrosion, broken connecting cable after aging, submerged buoy drifting and anchor chain corrosion breakage of a submerged buoy assembly, and observation data of the failed or lost submerged buoy cannot be recovered.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model provides a data recovery appearance for stealthily mark to at least, obtain the observation data of the stealthy mark that damages or loses.

According to the utility model discloses an embodiment, a data recovery appearance for stealthily mark includes the sealed cabin and sets up controller and the accumulator in the sealed cabin, and the controller is connected with the accumulator, still includes: a hollow float to which the capsule is fixed; the pressure sensor is arranged above the sealed cabin and is connected with the controller; a release device, the release device comprising: the first connecting part is connected below the sealed cabin, and the second connecting part is sleeved on the first connecting part; at least one connector disposed within the first connection; the magnetic part is arranged in the first connecting part and is abutted against at least one connecting part; the electromagnet is fixedly arranged in the first connecting part and is connected with the controller; the electromagnet is provided with at least one through hole corresponding to the connecting piece, the first connecting part is provided with at least one clamping groove, and under the condition that the electromagnet is not electrified, the connecting piece at least partially extends out of the at least one through hole and is clamped in the at least one clamping groove; when the electromagnet is energized, the at least one connecting piece is disengaged from the at least one card slot.

The controller may obtain a pressure parameter measured by the pressure sensor and determine from the pressure parameter whether the submersible buoy is within a normal operating depth range. When the submerged buoy is determined to be out of the normal working depth range, the submerged buoy can be judged to be failed or damaged at the moment, so that the controller controls the electromagnet to be electrified, at least one connecting piece is separated from at least one clamping groove, namely the first connecting part is disconnected with the second connecting part, the sealed cabin and the first connecting part can be separated from the failed or damaged submerged buoy structure and float to the water surface under the driving of the hollow floating body, the sealed cabin can not sink to the seabed along with the damaged submerged buoy, the sealed cabin can be conveniently recycled, and observation data stored in the storage in the sealed cabin can be obtained.

According to an embodiment of the utility model, the sealed cabin is fixed in the focus department of body. After first connecting portion and the separation of second connecting portion, the body can drive the sealed cabin come-up together, and the sealed cabin is fixed and can be reduced during the come-up and float upset and/or rocking that probably lead to because ocean current etc. when on the surface of water in the focus department of body, is favorable to overall structure's stability.

According to an embodiment of the utility model, a satellite communication device is arranged in the sealed cabin, the satellite communication device is connected with the controller, and the satellite communication device and the controller share the storage device; and a satellite communication antenna is also arranged above the sealed cabin, and the satellite communication device is connected with the satellite communication antenna. The satellite communication device can establish a connection with a communication device such as a ship or a shore to transmit observation data stored in a memory of the data recovery instrument to the communication device, and thus, even if the whole of the submerged buoy structure including the data recovery instrument is lost and cannot be recovered, the data can be recovered smoothly.

According to the utility model discloses an embodiment is provided with the solenoid valve on the sealed cabin, and the solenoid valve is connected with the controller to be provided with the inlet opening corresponding to the solenoid valve on the sealed cabin. The controller can control the electromagnetic valve to open to the sealed cabin can communicate with the external world, and the sea water can get into the sealed cabin through the electromagnetic valve (and the inlet opening that correspond) opened, makes the data recovery appearance sink the seabed self-destruction, prevents that other people from obtaining data wherein.

According to the utility model discloses an embodiment, the magnetic part includes ferromagnetic dish, with the dog of at least one connecting piece butt and connect the coupling rod between ferromagnetic dish and dog, the electro-magnet is used for driving ferromagnetic dish and drives the dog and remove to make at least one connecting piece break away from at least one draw-in groove. That is, under the condition that the electromagnet is not electrified, the stop block exerts force on the connecting piece through the contact with the connecting piece, so that the connecting piece is pressed in the clamping groove, and the connecting piece is clamped in the clamping groove. And when the electro-magnet circular telegram, the electro-magnet attracts the ferromagnetism dish to drive the dog and tend to break away from and remove with the butt of connecting piece, consequently, the direction of force change and/or the size of power that the dog was exerted on the connecting piece reduce, therefore the draw-in groove can "press back" the connecting piece stretch out the part outside the through-hole in first connecting portion, lead to the connecting piece to break away from the draw-in groove, the disconnection between first connecting portion and the second connecting portion.

According to an embodiment of the invention, the at least one connecting piece is a connecting ball, and the at least one clamping groove is configured to match with a part of the connecting ball extending out of the at least one through hole. It will of course be appreciated that the spherically shaped connector is less subject to friction and wear during "pressing back" into the first connection by the bayonet than is otherwise the case, and the connector will not be able to be pressed back into the first connection completely due to excessive friction or an improperly shaped click, ensuring successful separation of the first and second connections.

According to an embodiment of the present invention, the at least one connecting member comprises a wedge-shaped end portion and a rod portion fixed to the wedge-shaped end portion, the rod portion being sleeved with an elastic member; under the condition that the electromagnet is not electrified, the rod part at least partially extends out of the at least one through hole and is clamped in the at least one clamping groove, and under the condition that the electromagnet is electrified, the rod part is separated from the at least one clamping groove under the action of the elastic part. Similarly, in the case where the electromagnet is not energized, the stop exerts a force on the wedge-shaped end of the connector, which "presses" the rod portion into the slot, so that the connector is snapped into the slot, with the resilient member in a compressed state. When the electromagnet is energized, it attracts the ferromagnetic disc, which drives the stop block towards moving away from abutment with the wedge-shaped end, so that the direction of the force exerted by the stop block on the connecting piece changes and/or the magnitude of the force decreases, it being noted here that the resilient member, which is sleeved on the rod portion, contributes to this process, in addition to the fact that the catch groove tends to "press back" the portion of the rod portion of the connecting piece which protrudes out of the through hole into the first connecting portion. Advantageously, in this case, since the shape of the rod portion is not adapted to be pressed back directly by the snap groove, the force required for the rod portion to be "pressed back" into the first connection portion is mainly provided by the resilient member, i.e. the force exerted by the compressed resilient member on the wedge-shaped end portion.

According to an embodiment of the invention, the coupling rod is provided with a corrosion-resistant spring for keeping the stop in position. Under the condition that the electromagnet is not electrified, the elasticity of the corrosion-resistant spring is beneficial to keeping the stop block at the position abutted to the connecting piece, and the stability of the device is improved.

According to one embodiment of the present invention, the density of the data recovery instrument is between 0.99 g/cc and 1.00 g/cc. Such density can ensure that the data recovery instrument floats upward after escaping (the first connecting part and the second connecting part of the release device are separated), and the floating speed is not too high, so that the data recovery instrument can float a farther distance under the action of the flow of the seawater in the horizontal direction, and the data is prevented from being discovered by other people and salvaged, thereby losing data.

The submerged buoy comprising the data recovery instrument of the utility model also comprises a main floating ball and a submerged buoy controller arranged in the main floating ball; the latent mark controller is connected with the controller of the data recovery instrument in an optical fiber coupling mode. Since the transmission rate of the optical fiber is far greater than that of a common communication cable, observation data of other instruments of the submerged buoy connected with the submerged buoy controller can be rapidly transmitted to the data recovery instrument and stored in the storage under the condition that the submerged buoy is determined to be damaged; in addition, along with the separation of the data recovery instrument, the connection between the diving mark controller and the controller of the data recovery instrument is also disconnected, and if the traditional circuit connection is used, the circuit is easily short-circuited due to the entry of seawater during disconnection, so that further faults and damages are caused.

It is understood that the electromagnet 101 at least comprises a power supply (such as a storage battery) for supplying power and a relay, and the control signal sent by the controller 114 through the signal cable 120 can control the relay to open/close, so as to control the power supply to be switched on/off, so as to realize the power on/off of the electromagnet 101. Electromagnet 101 may be implemented in any suitable manner and structure known to those skilled in the art and therefore will not be described in detail herein.

Advantageously, the electromagnet 101 uses a static seal, which is cheap and reliable compared to the dynamic seal release 201 using a motor shaft.

As shown in fig. 2, 3 and 4, the float is advantageously shaped to mimic fish, for example, ray, bat ray and stingray are flat sea fish, which often swim along ocean currents with little resistance to seawater and sometimes jump above the sea surface. According to the sea area where the submersible buoy is placed, the floating body 116 with different appearances can be selected to imitate the appearance of a ray, a manta ray or a stingray, in the first embodiment, the floating body 116 imitates the appearance of the ray, the appearance of the ray is measured by a die line method through a die line and a template tool, the floating body 116 is processed by using a 3D printing technology, and the outer surface of the floating body 116 is coated with a coating imitating the skin on the upper surface of the ray, so that the floating resistance of the floating body 116 is small, and the floating distance is long; the shape and color mimic ray reduces the risk of exposure.

Preferably, the density of the data recovery instrument 200 ranges from 0.99 to 1.00 g per cubic centimeter, and the data recovery instrument 200 arranged in this way has small net buoyancy, slow floating, long drifting time and long drifting distance. The condition that the submerged buoy is directly floated out of the sea surface at the laying position of the submerged buoy is avoided, the laying position of the submerged buoy is exposed or the submerged buoy is obtained by a stolen taker is avoided, the probability of finding and salvaging by other people is reduced, and the probability of successfully recycling data through the data recycling instrument 200 is increased.

Preferably, the capsule 118 and release 201 are fixed by tapping at the center of mass (center of gravity) of the float 116. The data recovery instrument 200 except the floating body 116 is an axisymmetric revolving body, the materials of all parts are uniform, the sealed cabin 118 is in a circular truncated cone shape, and the mass center of each part in the sealed cabin 118 is arranged on the symmetric axis of the sealed cabin 118; the perpendicular line passing through the center of mass of the data recovery instrument 200 coincides with the perpendicular line passing through the center of mass of the float body 116; the data recovery instrument 200 is assembled and then tested in a storm water trough, and the satellite communication antenna 123 is reliably exposed out of the water for communication in the case of level 3 sea conditions. Such a configuration facilitates reducing sloshing of the data recovery instrument 200 after the data recovery instrument 200 has floated off the surface of the sea off the stainless steel support 213, facilitates reducing satellite communication power, and saves very limited battery power.

The work flow of the data recovery instrument 200 in the first embodiment is as follows: controller 114 detects the value of pressure sensor 121 and, in the event that the value of pressure sensor 121 is less than the depth threshold, controller 114 releases a release command to release device 201 (in other words, causes electromagnet 101 of release device 201 to be energized, as will be described in more detail below), and data recovery instrument 200 escapes, drifts and floats up from the point of potential containment. When the pressure sensor 121 connected with the data recovery instrument 200 detects that the pressure is atmospheric pressure, the data recovery instrument 200 is judged to float out of the sea, the controller 114 is connected with a laboratory satellite communication device of a submerged buoy placer through the satellite communication device 119, and further TCP/IP connection is established with a database server; the controller 114 prioritizes all data, sends the data in the order of data priority, sets the data priority according to the principle of the reason for facilitating data analysis of submerged buoy failure, and preferably sets the higher priority for the tension sensor data and the hydrophone 202 data at the escape time; after the data recovery instrument 200 completes all data forwarding on the storage 117 (in the first embodiment, the SD card), the solenoid valve disposed on the capsule 118 is opened, and the capsule 118 is submerged into the sea bottom for self-destruction through water entering through the solenoid valve.

The controller 114 also monitors the time, if the latest recovery time is exceeded, the controller 114 sends a release instruction to the relay of the electromagnet 101 of the release device 201 to release the data recovery instrument 200, the data recovery instrument 200 escapes, drifts and floats upwards to leave a submerged buoy defense deployment point, and after the data recovery instrument 200 arrives at the sea surface, the satellite communication device 119 establishes satellite communication connection with the data center of a deployer and further establishes TCP/IP connection with a database server to transmit data.

In addition, under the condition of normally recovering the submerged buoy, the satellite communication device 119 of the data recovery instrument 200 can replace a traditional beacon machine after the submerged buoy emerges from the sea surface, and the positioning function can be realized.

Advantageously, the float 116 may also be a convex lens shaped like a circle, thick in the middle and thin around, with a uniform mass distribution, with a center of mass coincident with the geometric center, with an opening at the center of mass of the float 216 to secure the capsule 218 and release structure.

It will of course be appreciated that the shape and configuration of the float body 116 may be designed and selected according to various requirements of actual needs, and that the above-described shape and configuration is only a preferred embodiment thereof and is not intended to limit the present invention.

Example two

Referring now to fig. 6, there is shown a submersible buoy according to a preferred embodiment of the present invention, the submersible buoy comprising a submersible buoy controller 215, a data recovery instrument 200, a release device 201, a hydrophone 202, an underwater acoustic communicator 203, an ADCP one 205, an ADCP two 214, a beacon 212, a stainless steel support 213, a main float 216, an instrument chain 217, a release 221, an anchor chain 211 and a gravity anchor 222.

The buoy controller 215 is installed in the pressure-resistant shell and fixed in a reserved cavity of the main floating ball 216. The stainless steel support 213 passes through a reserved hole of the main floating ball 216, the main floating ball 216 is fixed on the stainless steel support 213 by using a nut, the ADCP I205 and the ADCP II 214 are fixed on the reserved hole of the main floating ball 216 in a bolted connection mode, and the hydrophone 202, the underwater acoustic communicator 203 and the beacon 212 are fixed on the stainless steel support 213 by using stainless steel hoops. The second connection portion of the data recovery instrument 200 (configured as the connection bracket 110 similarly to the first embodiment) is rigidly connected to the stainless steel bracket 213 by a bolt. The bottom of the stainless steel bracket 213 is connected with an instrument chain 217; the lower end of the instrument chain 217 is connected with a releaser 221, and the releaser 221 is connected with a gravity anchor 222 through an anchor chain 211.

It should be understood here that the instrument chain is essentially a "chain" of connected instruments in a submerged structure, i.e., the portion indicated by the dashed box in fig. 6, in the embodiment shown in fig. 6, the instrument chain 217 is composed of a tension sensor one 206, a tension sensor two 210, a tension sensor three 219, a thermohaline gauge 207, small floating

balls

208, 220 and a single point current meter 209 which are connected by a mooring line 218 from top to bottom, and the instrument chain 217 may be added or subtracted with several other observation instruments, such as a deepwater nitrate gauge, a dissolved oxygen recorder, a temperature recorder, etc., depending on the observation elements, so that a plurality of instruments selected depending on the observation elements may be sequentially connected together by mooring lines to form the instrument chain 217.

It should also be understood that releaser 221 is used herein to release a submerged buoy, which may take any suitable configuration and form known in the art, rather than releasing device 201 for releasing data recovery instrument 200.

The submarine mark controller 215 is respectively connected with the data recovery instrument 200, the hydrophone 202, the underwater acoustic communicator 203, the ADCP I205, the ADCP II 214, the tension sensor I206, the tension sensor II 210, the tension sensor III 219, the thermohaline depth gauge 207, the single-point current meter 209, the beacon 212 and the releaser 221 through a signal cable 204, and preferably, the submarine mark controller 215 is connected with the controller 114 of the data recovery instrument 200 in a fiber coupling mode. Compared with conventional circuit connection, the optical fiber coupling can avoid the damage to the submerged standard controller 215 caused by circuit short circuit after the data recovery instrument 200 escapes; in addition, the optical fiber transmission rate is high, so that data of each instrument stored in the latent standard controller 215 can be collected several seconds before escaping, and the data of several seconds before escaping is key data for analyzing latent standard faults.

The tension sensor I206, the tension sensor II 210 and the tension sensor III 219 detect tension applied to the mooring cable, and the three tension sensors and the mooring cable form an intelligent rigging. The intelligent cable and the signal cable are combined into a composite cable, for example, the intelligent cable is installed in a foamed rubber pipe, the signal cable is uniformly and spirally wound on the foamed rubber pipe and then penetrates into a PVC protective pipe, and the spiral pitch is preferably 3 to 5 meters.

Preferably, the length of the signal cable is larger than the maximum length of the mooring cable after being elastically deformed and extended under the action of force, so that the signal cable is not pulled by other pulling forces except the dead weight. When the mooring cable elastically deforms, the foamed rubber tube can play a role in buffering.

Data reclaimer 200 may disengage and escape autonomously in the event of a failure of latency controller 215. The operation of the data recovery instrument 200 will now be described with reference to fig. 7:

1. controller 114 of data recovery instrument 200 initializes;

2. the controller 114 measures the water depth by measuring the pressure by the pressure sensor 121, and when the depth of the data recovery instrument 200 is greater than the depth threshold, the controller 114 determines that: the depth of the data recovery instrument 200 is normal, and the program is transferred to the step 3; when the depth of the data recovery instrument 200 is less than the depth threshold, the controller 114 determines that: if the depth of the data recovery instrument 200 is abnormal, the submerged buoy floats upwards, namely the submerged buoy is possibly damaged or salvaged, broken by a shackle or broken by a mooring cable, and the program is transferred to step 7; under the action of ocean current, the depths of the main floating ball 216 and the data recovery instrument 200 connected by using the stainless steel bracket 213 are changed constantly, so that the depth threshold value is defined as the sum of a certain error value and the depth of the data recovery instrument 200 fixed on the main floating ball 216 when the ocean current speed is zero;

3. the controller 114 judges the connection time, the controller 114 establishes connection with the latent icon controller 215, the controller 114 acquires data of the latent icon controller 215 according to the priority level, then encrypts and compresses the data, and the data is stored in the storage 117; setting data priority according to the principle of the reason for facilitating the application of data analysis subsurface buoy failure, preferably setting higher priority for the tension sensor data and the hydrophone 202 data at the escape moment;

4. the controller 114 reads the running state data of the acoustic communicator, judges whether the acoustic communicator works normally, and if the acoustic communicator is in failure, the program goes to step 7;

5. the controller 114 determines whether the submerged buoy deployment time exceeds the latest recovery time set by the deployer, and if the submerged buoy deployment time exceeds the latest recovery time, the process goes to step 7;

6. if the acoustic communicator is normal and is earlier than the latest recovery time, the controller 114 closes the connection between the controller 114 and the latency controller 215, and the procedure returns to the step 2;

7. the data recovery instrument drifts upwards to escape from the hidden buoy and distributes the prevention points: the controller 114 establishes connection with the latency controller 215, the controller 114 acquires data of the data latency controller 215 according to the priority level, and when the data transmission is completed or at a set minimum release depth, the controller 114 sends a release instruction to the release device 201 to release the data recovery instrument 200; the minimum release depth refers to a depth to which the data recovery instrument 200 floats up, and the data recovery instrument 200 is immediately released regardless of whether data is transferred; for example, the actual minimum depth of the normal working state of the data recovery instrument 200 is 500 meters, considering errors, 485 meters are set as a depth threshold value by the controller 114, the set minimum release depth is 300 meters, if the data transmission is finished when the data recovery instrument 200 floats to 350 meters, the controller 114 sends a release instruction to release the data recovery instrument 200 when the data recovery instrument 200 floats to 350 meters, and early release can enable the data recovery instrument 200 to have a longer drift distance with ocean currents and not be easily found by sea surface personnel and then fished; if the data recovery instrument 200 floats to 300 meters, no matter whether the data transmission is finished or not, the controller 114 immediately sends a release instruction to release the data recovery instrument 200;

8. in the drifting and floating process of the data recovery instrument 200, the controller 114 continuously measures pressure through the pressure sensor 121, when the pressure is equal to atmospheric pressure, the satellite communication device 119 is connected with a data center of a distributor to transmit data, the controller 114 prioritizes all data, sends the data according to the data priority, sets the data priority according to the principle of analyzing submerged buoy failure by using data conveniently, and sets higher priority for the tension sensor data and the hydrophone 202 data at the optimal escape time; after all data on the SD card are forwarded, the controller 114 finally opens the electromagnetic valve 101 arranged on the sealed cabin 118, and after the sealed cabin 118 enters water, the data recovery instrument 200 sinks into the sea bottom for self-destruction.

To sum up, the utility model provides a data recovery appearance 200 can break away from the submerged buoy automatically when judging the degree of depth anomaly of submerged buoy to data and instrument running state data storage that the instrument that will submerge the buoy observed before breaking away from are in the accumulator, so that break away from the back and communicate with the database server who guards the person through satellite communication device, do not retrieve the data of directly retrieving under the condition of the data recovery appearance 200 that breaks away from.
