[0030] Combine the following Figure 1-Figure 8 , through specific embodiments and application scenarios, a seabed base provided by an embodiment of the present invention is described in detail.

[0031] like Figures 1 to 3 As shown, the present invention provides a seabed foundation, comprising: an outer cover 1, an anti-sinking plate 2, a mounting bracket 3, a floating ball 4, a recovery rope 5 and a release mechanism 6. The outer cover 1 is connected to the anti-sinking plate 2 by a breaking bolt 7 to form an installation space. The mounting bracket 3 is fixed to the inner wall of the outer cover 1 and is located in the installation space. The installation space is separated by an accommodating cavity to accommodate a seismograph 100. The recovery rope 5 is connected to the mounting bracket 3 and the floating ball 4 respectively.

[0032] In the use state, the release mechanism 6 fixes the float 4 to the top wall of the outer cover 1 .

[0033] In the recovery state, the release mechanism 6 releases the float 4. The float 4 drives the outer cover 1 and the mounting bracket 3 to float to the sea surface through the recovery rope 5. The breaking bolt 7 is used to break when the recovery rope 5 is pulled by an external force, so that the anti-settling plate 2 and the outer cover 1 are separated.

[0034] like Figure 1As shown, the seabed base also includes a cable joint, a bearing head 10 and a bending reinforcement head 20. Each electrical component in the seabed base is electrically connected to the submarine cable through the cable joint. The bearing head 10 and the bending reinforcement head 20 are installed at the connection between the submarine cable and the seabed base cable joint. Among them, the bearing head 10 is used to fix the cable joint and improve the tensile strength of the cable joint. The bending reinforcement head 20 is used to prevent the submarine cable from being excessively bent and ensure the power-on performance of the electrical components in the seabed base.

[0035] like Figure 1 As shown, there are multiple breaking bolts 7. Multiple breaking bolts 7 are arranged at intervals along the outer edge of the anti-settling plate 2 to install the outer cover 1 to the anti-settling plate 2. The seismograph 100 and other equipment are installed in the installation space formed by the outer cover 1 and the anti-settling plate 2, and the seabed base is used to effectively block the damage of the ocean current to the instrument. Of course, in addition to installing the seismograph 100, the seabed base of the present invention can also be used to install other underwater operating equipment. The mounting bracket 3 is used to support the outer cover 1 to prevent the outer cover 1 from deformation and ensure that the outer cover 1 has sufficient protective strength. At the same time, the mounting bracket 3 is used to install other components of the fixed seabed base. A sacrificial anode is installed on the mounting bracket 3, and anti-biological attachment paint is sprayed to enhance the seawater corrosion resistance of the seabed base.

[0036] like Figure 4 As shown, the mounting bracket 3 and the seismograph 100 are both installed in the installation space. Among them, the multiple frames of the mounting bracket 3 are separated into accommodating cavities to accommodate the seismograph 100. Optionally, the seismograph 100 can be fixedly mounted on the mounting bracket 3. Alternatively, the seismograph 100 is suspended on the inner wall of the outer cover 1, and the stability of the seismograph 100 is maintained by means of the mounting bracket 3 to prevent the seismograph 100 from shaking greatly.

[0037] like Figure 1 and Figure 2 As shown, the float 4 is located outside the installation space. The mounting bracket 3 is provided with a plurality of lifting ears 341. The recovery rope 5 is curled in the installation space, and one end of the recovery rope 5 is fixedly connected to the float 4, and the other end is fixedly connected to the plurality of lifting ears 341 through a forked sling.

[0038] During the process of hoisting and using the seabed foundation, the buoy 4 is always fixed to the top wall of the outer cover 1 through the release mechanism 6. When the seismograph 100 needs to be recovered, the release mechanism 6 releases the buoy 4, so that the buoy 4 floats in the water, and the buoy 4 drives the entire seabed foundation to float up through the recovery rope 5. When the water workers find the buoy 4 on the water surface, they pull the recovery rope 5 upward, and the gap between the anti-sinking plate 2 and the outer cover 1 becomes larger. When the tension value of the recovery rope 5 is greater than the maximum anti-breaking tension value of the breaking bolt 7, the breaking bolt 7 breaks, the anti-sinking plate 2 and the outer cover 1 are separated, and the silt in the outer cover 1 is taken out together with the anti-sinking plate 2. The anti-sinking plate 2 is discarded in the water or recovered by the water workers, which reduces the overall weight of the seabed foundation and improves the anti-adsorption capacity of the seabed foundation. The water workers continue to pull the recovery rope 5 until the outer cover 1 and its internal structure float to the sea surface, completing the recovery of the seabed foundation.

[0039] In addition, a cleaning device, such as a small vibration motor, a vibration plate or a nozzle, may be added to the anti-settling plate 2 to accelerate the removal of silt and other adsorbents, further improving the anti-adsorption capacity of the seabed base.

[0040] The present invention provides a seabed foundation, wherein an outer cover 1 is connected to an anti-sinking plate 2 by a breaking bolt 7 to form an installation space, and an installation bracket 3 is fixed to the inner wall of the outer cover 1 and is located in the installation space to support the outer cover 1 and equipment such as a seismograph 100 in the installation space, thereby improving the overall strength of the seabed foundation; a recovery rope 5 is respectively connected to the installation bracket 3 and a buoy 4; during the hoisting and use of the seabed foundation, a release mechanism 6 always fixes the buoy 4 to the top wall of the outer cover 1; when the seabed foundation needs to be recovered, the release mechanism 6 releases the buoy 4, and the buoy 4 floats to On the sea surface, after the water workers find the buoy 4, they pull the recovery rope 5 upwards. When the tension value of the recovery rope 5 is greater than the maximum anti-breaking tension value of the breaking bolt 7, the breaking bolt 7 breaks, the anti-settling plate 2 and the outer cover 1 are separated, and the silt in the seabed base is brought out together with the anti-settling plate 2 to improve the anti-adsorption capacity of the seabed base. With the further pulling of the recovery rope 5, the outer cover 1 and its internal structure float to the sea surface, realizing the recovery of the seismograph 100. The present invention improves the convenience of recovering the seabed base, does not need to use frogmen, and has a high recovery efficiency of the seabed base.

[0041] In some embodiments, Figure 2 As shown, the release mechanism 6 includes an acoustic releaser 61, a release hook 62 and a ballast member 63. The float 4 is connected to a hook ring 41. The acoustic releaser 61 is fixed to the mounting bracket 3. The mounting bracket 3 is provided with a first connecting seat 31 and a second connecting seat 32. The release hook 62 and the ballast member 63 are rotatably mounted on the first connecting seat 31 and the second connecting seat 32 respectively. The end of the release hook 62 is hinged to the ballast member 63.

[0042] In the use state, the acoustic releaser 61 hooks the hinge between the release hook 62 and the ballast member 63 , and the release hook 62 is inserted into the hook ring 41 to fix the float 4 .

[0043] In the recovery state, the acoustic releaser 61 releases the release hook 62 and the ballast member 63 , and the release hook 62 is pressed down by the ballast member 63 to disengage from the hook ring 41 to release the float 4 .

[0044] The conventional method of using an acoustic releaser 61 to connect a single release hook 62 to lock the float 4 is that the release hook 62 mounted thereon is prone to tilting due to the weak locking thrust of the acoustic releaser 61. The tilted release hook 62 interacts with the lock of the acoustic releaser 61, resulting in the release hook 62 not being able to unhook smoothly, and the release sensitivity of the float 4 is low, thereby reducing the recovery rate of the seabed base. The present invention uses an acoustic releaser 61, a ballast 63, and a release hook 62 in linkage, which can effectively avoid external interference with the lock of the acoustic releaser 61 and ensure that the release hook 62 can unhook smoothly.

[0045] Specifically, the release hook 62 and the ballast member 63 can be rotatably mounted on the first connection seat 31 and the second connection seat 32 respectively through the pin shaft, so as to provide support for the release hook 62 and the ballast member 63 through the first connection seat 31 and the second connection seat 32. Optionally, the first connection seat 31 and the second connection seat 32 are anti-corrosion plates fixedly mounted on the mounting bracket 3. Alternatively, the first connection seat 31 and the second connection seat 32 are an integral structure with the mounting bracket 3.

[0046] Among them, Figure 2 As shown, the acoustic releaser 61 is installed between the first connecting seat 31 and the second connecting seat 32. The release hook 62 has a hooking portion and a connecting portion connected to each other. The hooking portion is inserted into the hook ring 41 of the float 4 to lock the float 4. The connecting portion and the ballast member 63 are hinged, and the two are respectively located at the bottom ends of the first connecting seat 31 and the second connecting seat 32, that is, they are respectively arranged on opposite sides of the acoustic releaser 61. When the float 4 is in a locked state, the lock of the acoustic releaser 61 hooks the hinge between the connecting portion and the ballast member 63. When the seabed base needs to be recovered, the surface deck unit transmits an acoustic signal to the acoustic releaser 61, and the lock under the acoustic releaser 61 opens. Under the downward pressure of the ballast member 63 and the buoyancy of the float 4, the release hook 62 is quickly unhooked from the hook ring 41, thereby improving the sensitivity of the release mechanism 6 to release the float 4.

[0047] In some embodiments, Figure 2 As shown, the ballast member 63 includes a connecting hook 631 and a ballast block 632. The connecting hook 631 is rotatably mounted on the second connecting seat 32. The end of the connecting hook 631 is hinged to the release hook 62. The ballast block 632 is hung on the connecting hook 631.

[0048] Specifically, the connecting hook 631 has a hook portion and an end portion. The ballast block 632 is hung on the hook portion of the connecting hook 631. Optionally, the ballast block 632 is a heavy object such as an iron block or a steel block. The hook portion of the connecting hook 631 and the hooking portion of the release hook 62 are arranged outward relative to the acoustic releaser 61. The hook portion of the connecting hook 631 and the hooking portion of the release hook 62 are respectively hinged to the second connecting seat 32 and the first connecting seat 31. The end portion of the connecting hook 631 and the connecting portion of the release hook 62 are hinged. When the float 4 is in a locked state, the lock of the acoustic releaser 61 hooks the connecting hook 631 and the release hook 62. When released, the lock of the acoustic releaser 61 simultaneously releases the connecting hook 631 and the release hook 62. Under the gravity of the ballast block 632 and the floating action of the float 4, the release hook 62 is quickly unhooked from the hook ring 41.

[0049] In some embodiments, Figure 4 and Figure 5 As shown, the seabed base also includes a latch, a guide member 9, a slider 30 and a connecting rope 40. The guide member 9 is fixed to the inner wall of the outer cover 1. The slider 30 is movably sleeved on the guide member 9. The slider 30 is fixed with a connecting ring 301. The connecting ring 301 passes through the outer cover 1. The latch is detachably inserted into the connecting ring 301. The slider 30 is connected to the seismograph 100 through the connecting rope 40. The anti-settling plate 2 has a through hole for the seismograph 100 to pass through.

[0050] Specifically, the guide member 9 can be a guide column extending in the vertical direction. The guide member 9 and the slider 30 are both located in the installation space. The guide member 9 is fixed to the inner wall of the outer cover 1, and the slider 30 is sleeved on the guide member 9 and can slide along the extension direction of the guide member 9. The slider 30 is connected to the seismograph 100 through a connecting rope 40. Optionally, the connecting rope 40 is a Kevlar rope. The connecting ring 301 passes through the outer cover 1. Before the seabed base is suspended, the pin is plugged into the connecting ring 301 to fix the position of the slider 30 and ensure that the seismograph 100 is firmly fixed in the installation space. When the seabed base is suspended, the pin is pulled out by the water operator. Under the obstruction of buoyancy, the slider 30 slowly moves down along the outer wall of the guide member 9, and the bottom of the seismograph 100 passes through a through hole, thereby ensuring that the seismograph 100 contacts the seabed before the anti-settling plate 2, eliminating the interference of the impact on the seabed base itself on the seismograph 100. When the seismograph 100 is deployed and contacts the seabed, the seismograph 100 and the outer cover 1 are coupled and contacted with the seabed. At this time, the connecting rope 40 is in a loose state, and the seismograph 100 is softly connected to the seabed.

[0051] The seismograph 100 is softly connected to the outer cover 1 through the slider 30, the connecting rope 40 and the guide member 9, which can ensure the stability of the seabed base during transportation and hanging, and eliminate the interference of the seabed base on the seismograph 100 when the seabed base is impacted by seawater. After the seabed base is laid, the seismograph 100 can be closely combined with the seabed, and the seismograph 100 has good adaptability, so that the seismograph 100 can accurately detect and record the earthquake situation of the seabed.

[0052] Furthermore, in some embodiments, Figure 4 and Figure 5 As shown, the seabed base further includes a limiting cylinder 50. The limiting cylinder 50 is fixed to the mounting bracket 3. The limiting cylinder 50 and the through hole are correspondingly arranged to guide the seismograph 100 to pass through the through hole from the inside of the limiting cylinder 50.

[0053] Specifically, two circular frames can be connected together by multiple guardrails arranged in an annular manner to form a limiting cylinder 50. The bottom of the limiting cylinder 50 is fixed to the mounting bracket 3 by bolts. A connecting hole is provided at a position corresponding to the through hole of the mounting bracket 3. The limiting cylinder 50 is arranged at the connecting hole. When the pin is pulled out, the seismograph 100 moves downward, and the bottom of the seismograph 100 is guided through the connecting hole and the through hole by the limiting cylinder 50 to prevent the seismograph 100 from tilting or shifting, avoid shaking of the seismograph 100 due to the connecting rope 40, and ensure the normal performance of the seismograph 100.

[0054] It should be noted that the guide member 9 is provided with a limiting structure for limiting the movable stroke of the slider 30, ensuring that the slider 30 and the fixed block always remain connected, thereby ensuring that the seismograph 100 and the seabed base always remain connected, which facilitates the deployment and recovery of the seismograph 100.

[0055] In some embodiments, Figure 4 As shown, two sets of latches, guide members 9, sliders 30, connecting ropes 40 and limit cylinders 50 are provided. Two sets of latches, guide members 9, sliders 30 and connecting ropes 40 are symmetrically installed in the installation space along the vertical direction to simultaneously install two seismographs 100. By symmetrically installing two seismographs 100, the entanglement of the connecting ropes 40 when a single seismograph 100 is installed is avoided, and the balance of the entire seabed base is improved to prevent the seabed base from tilting due to the shift of the center of gravity. At the same time, installing two seismographs 100 in one seabed base increases the installation capacity of the seabed base and saves installation costs.

[0056] In some embodiments, Figure 6 and Figure 7 As shown, the seabed foundation further includes a rope compartment 60. The rope compartment 60 is fixed to the mounting bracket 3. Two rope coiling columns 601 are arranged side by side in the rope compartment 60. The recovery rope 5 is cross-coiled on the two rope coiling columns 601.

[0057] Specifically, the rope compartment 60 is in the shape of an "8" when viewed from above, with the two ends being wide and the middle being narrow. A rope coiling column 601 is provided at each of the two wider ends of the rope compartment 60. The recovery rope 5 is coiled on the two rope coiling columns 601 in the shape of an "8", which improves the regularity of the coiling of the recovery rope 5 in the rope compartment 60, prevents the recovery rope 5 from floating and getting entangled or knotted under the buoyancy of seawater, and facilitates the release of the recovery rope 5, thereby improving the recovery rate of the seabed base. Before the recovery rope 5 is coiled in the shape of an "8", a certain length is reserved at the head end. After the rope is coiled, it is inserted into the two rope coiling columns 601. The head end of the recovery rope 5 is fixedly connected to the mounting bracket 3, and the tail end is fixedly connected to the buoy 4.

[0058] The traditional pagoda-shaped seabed foundation has strong stability on the seabed and can resist the effects of water flow and external forces, thus forming a strong obstacle to trawling operations. The larger bottom area of ​​the pagoda-shaped seabed foundation can also expand the blocking range of trawl nets, but due to its many edges and corners, it is easy to hook the fishing net, which will not only damage the trawl net and cause economic losses to fishermen, but also may cause safety problems, and also affect the normal operation of various components on the seabed foundation.

[0059] The seabed foundation provided by the present invention is as follows Figure 1 As shown, the anti-settling plate 2 is circular. The outer cover 1 is truncated cone-like. The outer cover 1 includes a cover plate 11 and a plurality of connecting plates 12. The plurality of connecting plates 12 are fixed to the mounting bracket 3, and the sides of two adjacent connecting plates 12 are fixedly connected. The top end of each connecting plate 12 is fixedly connected to the cover plate 11. The bottom end of each connecting plate 12 is connected to the anti-settling plate 2 by a breaking bolt 7. The cover plate 11 and the plurality of connecting plates 12 are arranged to form a truncated cone-shaped outer cover 1.

[0060] Among them, the connecting plate 12 and the cover plate 11 can be stainless steel plates. The connecting plate 12 is trapezoidal. Two adjacent connecting plates 12 are fixedly connected by bolts. The inner side of each connecting plate 12 is fixedly connected to the mounting bracket 3 to form an effective support for the outer cover 1 through the mounting bracket 3. The sides of multiple connecting plates 12 are connected in sequence, and the first connecting plate 12 and the last connecting plate 12 are fixedly connected to form a conical cylinder. Multiple bolts can be used to fix the cover plates 11 one by one on the top of the multiple connecting plates 12, and multiple breaking bolts 7 can be used to fix the multiple connecting plates 12 one by one on the outer edge of the anti-settling plate 2, thereby forming a truncated cone-shaped seabed base.

[0061] The quasi-truncated cone-shaped seabed foundation can make the center of gravity of its overall structure lower, increase the contact area between the seabed foundation and the seabed, and reduce the settlement of the seabed foundation. When facing complex underwater environments, the quasi-truncated cone-shaped seabed foundation has a strong anti-overturning ability and greater strength, effectively preventing fishing boats from trawling and drifting nets from damaging the entire seabed foundation. The outer surface of the outer cover 1 is smoothed to reduce the degree of adhesion of impurities such as seabed silt on the outer cover 1, and improve the anti-scouring ability of the seabed foundation. The quasi-truncated cone-shaped seabed foundation has fewer edges and corners, and its side is streamlined, with high stamping resistance and is not easy to hook fishing nets, which improves the safety of the seabed foundation. When the seabed foundation is placed, a multi-point balanced placement method is adopted to ensure that the seabed foundation will not roll over or tilt when the flow rate is high, effectively preventing the seabed foundation from tilting, collapsing or shifting.

[0062] In some embodiments, Figure 8 As shown, the mounting bracket 3 includes a bottom frame 33 and a plurality of support frames 34. The bottom ends of the plurality of support frames 34 are fixed to the outer edge of the bottom frame 33 at intervals. The top ends of the plurality of support frames 34 are fixed to the cover plate 11. The plurality of connecting plates 12 are fixed to the plurality of support frames 34 one by one.

[0063] Specifically, a cushion seat 35 is provided under the bottom frame 33. The cushion seat 35 is disc-shaped. A plurality of disc-shaped cushion seats 35 are evenly supported on the bottom frame 33 to improve the overall stability of the seabed foundation. The support frame 34 is arc-shaped to support the outer cover 1. The lifting lug 341 is provided on the support frame 34. A plurality of support frames 34 are spaced apart on the outer edge of the bottom frame 33 to form a truncated cone-shaped mounting bracket 3 similar in shape to the outer cover 1, so as to better support the outer cover 1 and various components in the installation space. A plurality of connecting plates 12 are fixed to a plurality of support frames 34 in a one-to-one correspondence to ensure the overall strength of the seabed foundation.

[0064] like Figure 4 As shown, the bottom frame 33 includes a plurality of cross beams 331 and a plurality of longitudinal beams 332. The plurality of cross beams 331 and the plurality of longitudinal beams 332 are arranged in a staggered manner to form a plurality of grid units. The anti-settling plate 2 is provided with a weight-reducing hole 21 corresponding to each grid unit of the bottom frame 33 to prevent the seabed foundation from being too heavy and sinking into the seabed mud, reduce the adsorption force of the seabed on the seabed foundation, and facilitate the recovery of the seabed foundation.
