[0002] The seafloor seismic observation base station is a device system used for earthquake monitoring and seismic activity data collection in the ocean. It collects seismic waves, pressure changes, seafloor movement and other data through seismometers to help scientists analyze seafloor activities, predict disasters such as earthquakes and tsunamis, and study the structure and geological evolution of the earth. At present, most seismometers can only work within the inclination range of ±30°. If the rated working angle is exceeded, the seismometer monitoring will fail.

[0029] Combine the following Figure 1-Figure 7, through specific embodiments and application scenarios, an undersea seismic observation base station provided by an embodiment of the present invention is described in detail.

[0030] like Figure 1 and Figure 2 As shown, the present invention provides a submarine earthquake observation base station, comprising: a seabed base 1, a seismograph 2, a floating ball 3, a locking member 4 and a protective tube 5. The protective tube 5 is fixedly installed on the seabed base 1. Figure 3 As shown, the float 3 is connected to the seismograph 2 via a tether 31. The seismograph 2 can be plugged into the protective tube 5. Figure 4 As shown, the protective tube 5 has a locking hole 51. The seismograph 2 has a first state and a second state during the deployment process.

[0031] In the first state, the float 3 is fixed to the seismograph 2 . The locking member 4 is inserted into the locking hole 51 to lock the seismograph 2 in the protective tube 5 .

[0032] In the second state, the locking member 4 is withdrawn from the protective tube 5. Under the action of external force, the seismograph 2 is pulled out of the protective tube 5. The cable is released so that the buoy 3 pulls the seismograph 2 down to the landfill pit on the seabed.

[0033] Specifically, Figure 1 and Figure 2 As shown, the seabed base 1 is in a frustum-like shape. The seabed base 1 is used to provide support for the protective tube 5 and other components, and effectively block the damage of ocean currents to various instruments through the seabed base 1. The protective tube 5 is fixed to the seabed base 1 and arranged vertically to ensure the overall stability of the seismograph 2 during construction and deployment, and effectively solve the problem of the seismograph 2 shaking left and right. Optionally, the protective tube 5 is a thin-walled cylinder.

[0034] The bottom end of the protective tube 5 is fixedly connected to the seabed base 1 through a fixing plate 14. A flat flange 53 is welded to the bottom end of the protective tube 5 to facilitate the connection between the protective tube 5 and the fixing plate 14. An inclined flange 54 is welded to the top end of the protective tube 5 to reduce the adsorption force of part of the seawater through the inclined surface of the inclined flange 54 and protect the cable of the seismograph 2. Figure 5 As shown, the fixing plate 14 is provided with a through hole 141 with a diameter slightly larger than the outer diameter of the seismograph 2, so that the bottom end of the seismograph 2 is seated in the fixing plate 14, which can not only effectively reduce the shaking of the seismograph 2, but also balance the water pressure inside and outside the protective tube 5 and reduce the adsorption force of seawater. Rubber seats are installed at the top and bottom of the seismograph 2 respectively to reduce the impact force received by the seismograph 2 when it sinks to the seabed.

[0035] like Figure 6 As shown, a handle is provided at the top of the seismograph 2 to facilitate the insertion and removal of the seismograph 2 and the tying of the tether 31. One end of the tether 31 is tied to the handle, and the other end is tied to the float 3 to achieve the connection between the float 3 and the seismograph 2.

[0036] like Figure 4 As shown, the outer wall of the protective tube 5 is convexly provided with a truncated cone structure 52. The locking hole 51 runs through the truncated cone structure 52 and the wall of the protective tube 5. The locking hole 51 is adapted to the locking member 4. Optionally, the locking member 4 is a pin shaft, and the locking hole 51 is a pin shaft hole.

[0037] Before deployment, first gather the tether 31 with the help of fixing parts such as straps to fix the float 3 on the handle, then insert the seismograph 2 into the protective tube 5, and then pass the pin through the pin hole so that the inner end of the pin is suspended above the seismograph 2 to form a stop for the seismograph 2 to prevent the seismograph 2 from escaping from the top of the protective tube 5.

[0038] The process of the seismograph 2 sinking from the sea surface to the seabed is defined as the first state of the seismograph 2. The process of the seismograph 2 sinking from the seabed to the landfill pit on the seabed is defined as the second state of the seismograph 2. Figure 1 and Figure 2 As shown, a plurality of lifting ears 113 are provided at the top of the seabed base 1. In the first state, the plurality of lifting ears 113 are connected by a lifting rope to slowly sink the seabed base 1 and all the components installed on the seabed base 1 into the seawater. After the seabed base 1 enters the water to a certain depth, the lifting rope is unhooked, and the seabed base 1 and all the components installed on the seabed base 1 fall vertically under their own gravity and sit on the surface of the seabed base 1. When the seabed base 1 is located on the seabed surface, the underwater frogman takes out the locking member 4 from the lock hole 51, then extracts the seismograph 2, takes the seismograph 2 out of the protective tube 5, and the seismograph 2 falls to the flat seabed surface under its own gravity. Subsequently, the underwater frogman operates the equipment to flush the seabed surface to flush out a landfill pit of a certain size; then the straps are untied to release the float 3, and the seismograph 2 falls into the landfill pit under the guidance of the frogman and the float 3, ensuring the stable sinking of the seismograph 2; then, the tether 31 is cut to recover the float 3, completing the deployment of the entire seabed seismic observation base station.

[0039] The present invention provides an undersea seismic observation base station, wherein a seabed base 1 is used to provide support for various components. A seismograph 2 is inserted into a protective tube 5 during its sinking from the sea surface to the seabed, so as to form physical protection for the seismograph 2 through the protective tube 5 and reduce the impact force of seawater on the seismograph 2. A locking piece 4 is passed through a locking hole 51 to form a stopper for the seismograph 2 and prevent the seismograph 2 from escaping from the protective tube 5. When the seabed base 1 is located on the seabed surface, an underwater frogman takes out the locking piece 4, pulls up the seismograph 2, and releases the buoy 3 at the same time. Driven by the frogman and the buoy 3, the seismograph 2 sinks steadily into a landfill pit on the seabed, thereby completing the deployment of the entire undersea seismic observation base station. The seismograph 2 has high deployment flatness and low construction difficulty, thereby improving the monitoring effectiveness of the seismograph 2.

[0040] In some embodiments, Figure 7As shown, the locking member 4 includes a locking pin 41. The outer wall of the locking pin 41 is provided with a plurality of pressing blocks 411. The plurality of pressing blocks 411 are arranged side by side. In the first state, the locking pin 41 can be screwed into the locking hole 51, and the plurality of pressing blocks 411 are all against the seismograph 2.

[0041] The locking member 4 also includes a handle 42. The handle 42 is square to facilitate the frogman to hold it. The handle 42 is fixed to the outer end of the locking pin 41. Among them, the handle 42 and the locking pin 41 can be an integral structure. A plurality of clamping blocks 411 are arranged at intervals along the axial direction of the locking pin 41. Optionally, the number of the clamping blocks 411 can be two, three or five, etc., which is not specifically limited. After the seismograph 2 is inserted into the protective tube 5, the handle 42 is held to insert the locking pin 41 into the locking hole 51, and then the locking member is rotated 490° so that the plurality of clamping blocks 411 are respectively against the top of the seismograph 2, thereby realizing the locking of the seismograph 2 by the locking member 4. When it is necessary to unlock the seismograph 2, it is only necessary to rotate the locking member 490° in the opposite direction and then pull the locking member 4 out of the locking hole 51.

[0042] Furthermore, if Figure 7 As shown, in some embodiments, at least one stopper 412 is protruded from the outer wall of the locking pin 41. The stopper 412 and the pressing block 411 are arranged on opposite sides of the locking pin 41 along the axial direction of the locking pin 41. In the first state, the stopper 412 abuts against the inner wall of the protective tube 5.

[0043] In this embodiment, the clamping block 411 is located on the same side of the locking pin 41, and the stop block 412 is located on the other side of the locking pin 41, so that when the locking member 4 locks the seismograph 2, the stop block 412 and the inside of the protective tube 5 abut against each other to form a limit at the locking hole 51, thereby preventing the locking member 4 from escaping from the locking hole 51 by itself, and further ensuring the limiting effect of the locking member 4 on the seismograph 2.

[0044] In some embodiments, the protective tube 5 is provided in plurality. Figure 1 and Figure 2 As shown, the seabed base 1 includes a deployment frame 11 and an anti-settling plate 12. The bottom end of the deployment frame 11 is fixed to the anti-settling plate 12 to form an installation space between the deployment frame 11 and the anti-settling plate 12. A plurality of protective tubes 5 are arranged at opposite sides of the installation space, and each protective tube 5 can be inserted with a seismograph 2.

[0045] Specifically, Figure 1 and Figure 2As shown, the anti-settling plate 12 is rectangular. The deployment frame 11 is in the shape of a frustum. The outer edge of the bottom end of the deployment frame 11 is fixed in contact with the outer edge of the anti-settling plate 12. Optionally, there are two protective tubes 5, and the two protective tubes 5 are arranged on both sides of the diagonal of the installation space to prevent the seabed base 1 from excessively tilting due to the low center of gravity, so as to ensure that the seismograph 2 is laid relatively flat. Among them, the size of each protective tube 5 can be different, so as to insert seismographs 2 of different specifications. Optionally, the number of protective tubes 5 can also be three, and the three protective tubes 5 are arranged in an equilateral triangle. Alternatively, the number of protective tubes 5 can also be four, and the four protective tubes 5 are respectively arranged at the four corners of the anti-settling plate 12. As long as the relative stability of the seismograph 2 can be maintained during deployment, the present invention does not make specific limitations on this.

[0046] like Figure 1 As shown, a sacrificial anode is also installed on the deployment frame 11 and anti-biological attachment paint is sprayed to enhance the seawater corrosion resistance of the seabed base 1.

[0047] In some embodiments, Figure 1 As shown, in order to further prevent the seismograph 2 from excessively tilting during deployment and to ensure overall balance, a plurality of counterweights 6 are fixedly mounted on the anti-settling plate 12. The plurality of counterweights 6 are arranged at intervals along the outer edge of the anti-settling plate 12 so that the center of gravity of the entire seabed base 1 is maintained in its central area, thereby enabling the seismograph 2 to sink within a relatively small inclination range, thereby ensuring the normal operation of the seismograph 2 and the accuracy of the measurement.

[0048] In some embodiments, Figure 2 As shown, the laying frame 11 is provided with a plurality of cable coiling assemblies. The plurality of cable coiling assemblies correspond one to one with the plurality of seismographs 2. The cable coiling assemblies are used to coil the cables of the seismographs 2.

[0049] Specifically, each seismograph 2 is equipped with a cable for transmitting data and power. The cable coiling assembly is used to store and coil the cables of the seismograph 2 to effectively manage and retract the cables of the seismograph 2 to avoid cable entanglement or damage.

[0050] Optional, such as Figure 2 As shown, the cable coiling assembly includes four cable coiling poles 111. The four cable coiling poles 111 are arranged at four corners, and the cables of the seismograph 2 are coiled along the diagonal crosses of the four cable coiling poles 111.

[0051] Specifically, each winding pole 111 is welded to the deployment frame 11. The cable of the seismograph 2 is wound on the four winding poles 111 in an "8" shape, which improves the regularity of the winding of the seismograph 2 on the seabed base 1, prevents the cable of the seismograph 2 from floating and getting entangled and knotted under the buoyancy of seawater, and facilitates the release of the cable of the seismograph 2. The cable of the seismograph 2 has a sufficient winding length so that the buried position of the seismograph 2 can be adaptively adjusted to the position of the seabed base 1, which facilitates the underwater frogman to adaptively release the cable according to the distance between the two, and ensures the communication connection between the seismograph 2 and the relevant components in the seabed base 1.

[0052] like Figure 2 As shown, at least part of the deployment frame 11 is installed with an anti-trawling structure 112. When facing a complex underwater environment, the anti-trawling structure 112 can shield several scattered components in the deployment frame 11 to effectively prevent the trawling and drift nets of fishing boats from damaging the entire seabed base 1. At the same time, the anti-trawling structure 112 can enhance the anti-overturning ability of the seabed base 1 and improve the anti-scouring ability of the seabed base 1.

[0053] The anti-trawling structure 112 is provided with a plurality of weight-reducing holes 1121 to prevent the seabed base 1 from being too heavy and sinking into the seabed mud, thereby reducing the adsorption force of the seabed on the seabed base 1 and facilitating the recovery of the seabed base 1 .

[0054] like Figure 1 and Figure 2 As shown, an optoelectronic separation cabin 7 and an electric control cabin 8 are installed in the seabed base 1. An optoelectronic composite connector 13 is provided in the seabed base 1. The axial and horizontal directions of the optoelectronic separation cabin 7 are kept consistent so that the optoelectronic composite cable can be installed horizontally. A controller is installed in the electric control cabin 8. The seismograph 2 is connected to the controller. The controller is connected to the optoelectronic composite cable. The optoelectronic composite cable is connected to the sea cable through the optoelectronic composite connector 13.

[0055] Among them, considering the bending radius of the optoelectronic composite cable, the optoelectronic separation cabin 7 is installed on the anti-settling plate 12 in the horizontal direction through a clamp and a meniscus. In order to ensure the reasonable layout of the seabed base 1, the electric control cabin 8 is installed on the anti-settling plate 12 in the vertical direction. Since the optoelectronic separation cabin 7 and the electric control cabin 8 do not need to be disassembled after being laid, they can be installed in the installation space. By laying the optoelectronic separation cabin 7, the electric control cabin 8 and the protective tube 5 on the seabed base 1, the seismograph 2 and its auxiliary devices are integrated as a whole to achieve real-time observation on the shore-based platform.

[0056] like Figure 1As shown, the seabed base 1 also includes an optoelectronic composite connector 13, a bearing head 15 and a bending reinforcement head 16. The optoelectronic composite cable is connected to the submarine cable through the optoelectronic composite connector 13. The bearing head 15 and the bending reinforcement head 16 are installed at the connection between the submarine cable and the optoelectronic composite connector 13. Among them, the bearing head 15 is used to fix the optoelectronic composite connector 13 and improve the tensile strength of the optoelectronic composite connector 13. The bending reinforcement head 16 is used to prevent the submarine cable from being excessively bent, ensuring the power and communication transmission quality of each device of the submarine seismic observation base station.

[0057] The optoelectronic separation cabin 7 is mainly used to fix and protect the optoelectronic composite cable connected to the seabed base 1 to prevent the submarine cable from being damaged by bending. The optoelectronic separation cabin 7 is also used to separate the optical fiber unit and the power unit. The separated optical fiber unit and the power unit are connected to the controller through a watertight optical connector and a watertight electrical connector respectively.

[0058] The controller is the equipment terminal and transfer platform of the power transmission network and the communication link network. Through underwater high-density medium and low voltage power conversion technology and multi-protocol adaptive conversion technology, it realizes multi-level medium and low voltage power output and distribution and external supply of multiple communication protocols, provides energy distribution and communication transfer for the seismograph 2, and realizes the organic combination of the seismograph 2 and the backbone network.

[0059] In some embodiments, Figure 2 As shown, the seabed seismic observation base station also includes a camera 9 and an alarm. The camera 9 and the alarm are both installed on the seabed base 1. The shooting field of the camera 9 is toward the seismograph 2. The camera 9 is electrically connected to the controller, and the controller is electrically connected to the alarm.

[0060] During deployment, the image of the seismograph 2 is captured by the camera 9 and transmitted to the controller. The controller identifies the inclination of the seismograph 2 based on the image information, and controls the alarm to sound an alarm when the inclination of the seismograph 2 is too large, so as to prompt the underwater frogman, ensure that the underwater frogman can take relevant measures to correct the seabed base 1 in time, ensure that the seismograph 2 is always within a reasonable inclination range, and ensure the effectiveness of the deployment of the seismograph 2. Optionally, the alarm is a buzzer.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
