Description

Technical Field

[0001] The invention belongs to the field of marine oil seismic exploration, and in particular relates to a seabed node clock module shock absorbing structure. Background Art

[0002] Marine seismic exploration is usually carried out by artificially exciting seismic waves, and multiple seabed nodes arranged on the seabed receive the reflected waves from the formation. Seabed node seismic acquisition technology is aimed at seabed seismic acquisition scenarios. It integrates marine seismic data receivers (detectors) and corresponding clock units, data storage and batteries, etc., and has independent data recording units arranged on the seabed for seismic data acquisition. The four-component detectors equipped on the seabed nodes can greatly improve the quality of geological imaging, and the distributed node layout is flexible, which can meet the technical requirements of wide azimuth and high coverage, and can better meet the needs of seismic acquisition operations under complex sea conditions such as offshore oil field facilities. Therefore, it is increasingly valued in the current field of seabed seismic exploration technology.

[0003] Seafloor nodes are multi-component seismic data recording instruments that are independently distributed underwater. A single operation involves the retraction and deployment of thousands of seafloor nodes. The impact and collision during the retraction and deployment process will cause severe vibrations in the internal circuits of the seafloor nodes, resulting in damage to the internal circuit components of the nodes. Among them, the clock module is a very easy-to-damage component. Therefore, how to prevent the internal clock module of the seafloor node from being damaged due to impacts during operation is a problem that needs to be faced. Summary of the invention

[0004] In order to solve all or part of the above problems, the present invention aims to provide a shock absorbing structure for a submarine node clock module to reduce the impact on the clock module and extend its service life.

[0005] The present invention provides a shock-absorbing structure for a submarine node clock module, comprising: a flexible carrier board, on which a clock module is arranged to separate the clock module from a collection circuit; and a flexible connecting section, wherein two ends of the flexible connecting section are respectively connected to the flexible carrier board and the collection circuit, wherein at least the flexible connecting section is constructed to be able to generate elastic deformation under the action of an external force.

[0006] In some embodiments, the flexible carrier and the flexible connecting section are made of flexible metal material.

[0007] In some embodiments, a soft sheath is further included, which is sleeved and wrapped around the outer wall of the clock module, and the soft sheath is constructed to be able to produce elastic deformation under the action of external force.

[0008] In some embodiments, the material of the soft sheath is silicone.

[0009] In some embodiments, a wrapping cavity is formed in the soft protective cover, the cavity body of the wrapping cavity is matched with the outer peripheral wall of the clock module, and an opening is formed at the top of the wrapping cavity.

[0010] In some embodiments, the soft sheath further includes a limiting wall arranged parallel to and opposite to the top of the wrapping cavity, a groove is formed at the bottom of the limiting wall on the opposite inner side, and two sides of the flexible carrier are arranged in the groove.

[0011] In some embodiments, a control circuit is disposed on the flexible carrier board, and the clock module is electrically connected to the acquisition circuit via a connector in the control circuit.

[0012] In some embodiments, the clock module is powered by current input from the acquisition circuit.

[0013] In some embodiments, the frequency signal output by the crystal oscillator in the control circuit is converted by an inverter and then input into the acquisition circuit through a connector.

[0014] In some embodiments, a temperature sensor is also integrated in the control circuit, and the temperature sensor is used to detect the temperature of the clock module in real time.

[0015] It can be seen from the above technical solution that the shock-absorbing structure of the submarine node clock module provided by the present invention makes the clock module independent of the acquisition circuit and wraps it with flexible materials on all sides, which can effectively reduce the impact on the clock module, effectively protect the clock module, reduce the failure rate of submarine nodes, and reduce operation and maintenance costs.

[0021] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the shock-absorbing structure of the submarine node clock module of the present invention in conjunction with the accompanying drawings.

[0022] Figure 1 The structure of the seafloor node clock module shock absorbing structure 100 according to an embodiment of the present invention is shown. Figure 2 FIG. 1 shows a structural explosion diagram of a submarine node clock module shock absorbing structure 100 according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the submarine node clock module shock-absorbing structure 100 includes: a flexible carrier 1, on which a clock module 200 is arranged to separate the clock module 200 from the acquisition circuit; and a flexible connecting section 2, at both ends of which are respectively connected to the flexible carrier 1 and the acquisition circuit. Among them, at least the flexible connecting section 2 is constructed to be able to generate elastic deformation under the action of external force.

[0023] In the prior art, the seabed node seismic acquisition technology is oriented to the seabed seismic acquisition scenario, integrating the marine seismic data receiver (detector) and the corresponding clock unit (clock module 200), data storage and batteries, etc., and having an independent recording data unit arranged on the seabed for seismic data acquisition. In the present application, according to the seabed node clock module shock absorbing structure 100 of the embodiment of the present invention, the clock module 200 is independently arranged on the flexible carrier 1, and is connected to the acquisition circuit through the flexible connecting section 2. Among them, the flexible connecting section 2 is constructed to be able to produce elastic deformation under the action of external force, and the external force can be understood as external force such as vibration or impact. Under the effect of elastic deformation, the impact can be effectively prevented from being transmitted to the clock module 200, thereby effectively reducing the damage to the clock module 200.

[0024] In some embodiments, the flexible carrier 1 and the flexible connecting section 2 are made of flexible metal material.

[0025] In the present application, the flexible metal material may be a copper sheet, or other metal materials, as long as it can produce a certain amount of deformation during application.

[0026] Please refer to Figure 3 and Figure 4 In some embodiments, the submarine node clock module shock absorbing structure 100 may further include a soft sheath 3, which is sleeved and wrapped around the outer wall of the clock module 200. The soft sheath 3 may be constructed to be able to produce elastic deformation under the action of external force.

[0027] Through the above-mentioned arrangement, the outer wall of the clock module 200 is provided with a soft sheath 3 with elastic deformation, which can provide a certain buffering performance. External force directly acts on the soft sheath 3, which can directly reduce the impact on the clock module 200, thereby providing a better protection effect for the clock module 200, and further effectively reducing the failure rate of the submarine nodes and reducing the operation and maintenance costs.

[0028] In some embodiments, the material of the soft sheath 3 may be silicone, so that the soft sheath 3 can be constructed as a low-cost silicone soft sheath 3. Of course, it can also be other materials, as long as it can produce a certain amount of deformation during use.

[0029] Please continue to refer to Figure 3 and Figure 4 In some embodiments, a wrapping cavity 31 is formed in the soft sheath 3 , the cavity of the wrapping cavity 31 is adapted to the outer peripheral wall of the clock module 200 , and an opening 311 is formed at the top of the wrapping cavity 31 .

[0030] Through the above arrangement, the silicone soft sheath 3 is a hollow structure, and the hollow structure is formed into a rectangular structure similar in shape to the clock module 200 , so that it is easy to place and install, and can also better limit and fix to prevent the clock module 200 from shaking.

[0031] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the soft sheath 3 may further include a limiting wall 32 arranged parallel to and opposite to the top of the wrapping cavity 31, and a groove 321 is formed at the bottom of the relatively inner side of the limiting wall 32, and both sides of the flexible carrier 1 are arranged in the groove 321.

[0032] Through the above arrangement, the two sides of the flexible carrier 1 are arranged in the groove 321, which can further limit the clock module 200 from coming out, so as to further fix the clock module 200. In addition, when the clock module 200 is placed and installed, since the soft cover 3 is a silicone soft cover 3, the limiting wall 32 can be deformed outwards to freely place or take out the clock module 200.

[0033] Please refer to Figure 5 In some embodiments, a control circuit is disposed on the flexible carrier 1, and the clock module 200 is electrically connected to the acquisition circuit through a connector in the control circuit.

[0034] Please continue to refer to Figure 5 In some embodiments, the clock module 200 is powered by the current input by the acquisition circuit.

[0035] Please continue to refer to Figure 5 In some embodiments, the frequency signal output by the crystal oscillator in the control circuit is converted by an inverter and then input into the acquisition circuit through a connector.

[0036] In the present application, the flexible carrier 1 sets the clock module 200 independently from the acquisition circuit and connects it to the acquisition circuit through a connector. The clock module 200 is powered by the current input from the acquisition circuit through the connector, and the frequency signal output by the crystal oscillator is converted by the inverter and input to the acquisition circuit through the connector.

[0037] Please continue to refer to Figure 5 In some embodiments, a temperature sensor is also integrated in the control circuit, and the temperature sensor is used to detect the temperature of the clock module 200 in real time.
