Description

Technical Field

[0001] The present invention relates to the field of monitoring equipment, in particular to equipment for monitoring submarine landslides. Background Art

[0002] As a geological disaster, submarine landslides have many hazards and often have serious consequences. (1) Submarine landslides may directly break or damage submarine optical cables, resulting in communication interruption. For example, the submarine landslide triggered by the 7.0 magnitude earthquake in Pingtung, Taiwan, China in 2006 caused more than ten submarine optical cables to be broken, seriously affecting communications in Southeast Asia and even the world for more than a month. (2) Submarine landslides may impact drilling platforms, causing them to capsize or be damaged, threatening the safety of offshore workers. (3) The huge waves and debris flows generated by submarine landslides may impact port and terminal facilities, causing damage to terminal facilities and shutdown. (4) Submarine landslides may damage submarine oil and gas pipelines, cables and other pipelines, resulting in resource leakage, energy interruption, etc. (5) Large submarine landslides can trigger tsunamis, causing greater damage. The huge waves of tsunamis can impact cities and infrastructure in coastal areas, causing casualties and property losses. For example, the tsunami caused by the Sturga submarine landslide had a wave height of 3-20 meters, which had a serious impact on the North Atlantic coastal areas. (6) Submarine landslides may destroy the submarine ecosystem, affect the habitat and food chain of marine organisms, and lead to a reduction in biodiversity.

[0003] The damage to facilities, resource leakage and ecological damage caused by submarine landslides will bring huge economic losses. Repairing and rebuilding damaged facilities, restoring ecosystems and compensating for related losses all require huge capital investment. Therefore, submarine landslide monitoring is of great significance for ensuring the safety of marine engineering construction and resource exploitation, maintaining the economic and social security development of coastal areas, improving disaster warning and response capabilities, and promoting scientific research and technological innovation.

[0004] The submarine landslide monitoring equipment mainly consists of a monitoring equipment part, a fixing part and other functional parts. It is used to monitor the dynamic changes of submarine landslides in real time and provide important data on landslide displacement, deformation and stability to support early warning and prevention of geological disasters. Traditional submarine landslide monitoring equipment is fixed by vertical insertion into the landslide. The impact of the submarine water flow will cause the monitoring equipment to loosen and shake, or even detach from the fixing hole, seriously affecting the accuracy and reliability of the monitoring data. To this end, the patent of this invention proposes a new submarine landslide monitoring equipment. Summary of the invention

[0009] Preferably, the lower end portion of the screw rod is configured to be non-threaded; through the configured screw rod, when the water flow drives the turbine to rotate, and the turbine in turn drives the screw rod to rotate, causing the rotating ring to move to the non-threaded area of ​​the screw rod, the rotating ring will rotate with the screw rod to ensure that the rotating ring will no longer move downward through the thread.

[0010] Preferably, the upper end of the drill bit housing is fixedly connected to an oil tank, an oil groove is provided inside the oil tank, the outer wall of the screw is threadedly connected to a rotating ring, the rotating ring is rotatably connected to the rotating rod, a plurality of ball openings are provided inside the rotating ring, the surface of the ball opening is fixedly connected to a ball spring, and one end of the ball spring is fixedly connected to an oil-lubricating ball; through the arranged oil-lubricating ball, when the rotating ring reaches the unthreaded area of ​​the screw and rotates with the screw, the oil-lubricating ball is compressed and rebounded by the ball spring in the ball opening and pushed out, so that the oil-lubricating ball contacts the lubricating oil in the oil groove, and some of the lubricating oil is smeared out to lubricate the rotating ring and the oil tank, thereby avoiding excessive friction between the oil tank and the rotating ring, causing wear of parts, deteriorating sealing performance, and allowing seawater and substances in seawater to enter, causing corrosion to the main body of the monitoring equipment, affecting the normal operation of the main body of the monitoring equipment, thereby improving the reliability and safety of the device.

[0011] Preferably, the top of the oil tank is fixedly connected to a gas tank, the inside of the gas tank is slidably connected to a piston, the top of the piston is fixedly connected to a piston push rod, the outer wall of the piston push rod is sleeved with a high-pressure spring, the high-pressure spring is placed between the piston and the inner wall of the gas tank, the bottom end of the gas tank is provided with a first connecting port, the top of the oil tank is provided with a second connecting port, the first connecting port is aligned with the center of the second connecting port; through the set gas tank, when the rotating ring moves to the non-threaded area of ​​the screw rod and the water flow continues to drive the turbine to rotate, the rotating ring rotates with the turbine through the screw rod, and the roller The ball spring inside the ball mouth compresses and rebounds to push the lubricating ball to contact the oil groove in the oil tank at the oil outlet, and the lubricating ball rolls and sticks to the lubricating oil to lubricate the rotating ring and the oil tank. After multiple lubrications, the high-pressure spring in the gas tank compresses and rebounds to push the lubricating oil closer to the oil outlet, avoiding the problem that the amount of lubricating oil applied by the lubricating ball decreases after multiple lubrications, and the friction between the oil tank and the rotating ring increases. The increased friction will affect the sealing of the device, causing seawater to penetrate into the main body of the monitoring equipment to corrode the monitoring device, affecting the accuracy of the monitoring data, thereby improving the safety of the device.

[0012] Preferably, a mechanical sealing ring is arranged above the rotating ring, and a sealing pressure plate is arranged above the mechanical sealing ring.

[0013] Preferably, the radius of the nail opening is larger than the maximum radius of the fixing nail; when the rotating ring moves downward, the fixing nail extends outward through the inner wall of the nail opening, thereby avoiding the problem of the fixing nail being stuck in the nail opening when extending obliquely.

[0014] Preferably, a plurality of support rods are fixedly connected between the two connecting rings, and the support rods are evenly distributed on the outer wall of the rotating rod. Through the arranged support rods, when the rotating ring moves downward and pushes the fixing nails to extend and insert into the landslide, the three groups of fixing nails can be extended at the same time.

[0016] Preferably, the volume inside the gas tank is larger than the volume of the oil tank inside the oil tank; when the rotating ring moves to the unthreaded area of ​​the screw rod and the water flow continues to drive the turbine to rotate, the lubricating oil in the oil tank decreases, and the high-pressure spring inside the gas tank pushes the compression rebound to push the piston. The piston pushes the gas in the gas tank into the oil tank, pushing the lubricating oil close to the oil outlet, thereby avoiding the problem that when the lubricating oil decreases, the lubricating ball rolls on less lubricating oil, which reduces the lubrication ability and affects wear, thereby improving the reliability of the device.

[0018] 1. The present invention provides a reinforcement component. When water flows through the device that has been inserted into the landslide, the turbine rotates to drive the screw to rotate, and the screw rotation drives the rotating rod to move downward. The downward movement of the rotating rod pushes the connecting ring to move downward, and the connecting ring drives the rotating shaft and the limiting block to move downward. When the tip of the fixing nail touches the inner wall of the nail mouth, the rotating shaft starts to rotate. During the process of the connecting ring driving the rotating shaft to continue to move downward, the rotating shaft rotates, and the rotation of the rotating shaft drives the fixing nail to rotate. The fixing nail slowly extends outward through the nail mouth and is inserted into the landslide, thereby avoiding the device being affected by the water flow on the landslide, causing shaking, and then affecting the accuracy of the monitoring data, thereby improving the stability of the device in the landslide, and thereby improving the accuracy of the equipment monitoring data.

[0019] 2. The present invention provides a gear assembly, when the water flow drives the turbine to rotate counterclockwise, the turbine drives the gear ring to rotate, when the gear ring meshes with the special-shaped teeth, the special-shaped teeth shrink into the special-shaped groove, so that the gear ring cannot drive the special-shaped gear to rotate; when the water flow drives the turbine to rotate clockwise, the turbine drives the gear ring to rotate, the gear ring and the special-shaped teeth complete meshing, the gear ring drives the special-shaped gear to rotate, the special-shaped gear drives the screw rod to rotate, the rotation of the screw rod drives the rotating rod to move downward and pushes the connecting ring to move downward, the connecting ring drives the fixing nail to move downward, and during the downward movement of the fixing nail, the nail mouth slowly extends outward and is inserted into the landslide, thereby avoiding the problem that the screw rod is controlled by water flow in different directions to rotate, causing the fixing nail to wander in the nail mouth and cannot be fully inserted into the landslide, thereby improving the reliability of the device.

[0020] 3. The present invention provides an air tank. When the rotating ring moves to the unthreaded area of ​​the screw and the water flow continues to drive the turbine to rotate, the rotating ring rotates with the turbine through the screw. The ball spring inside the ball mouth compresses and rebounds to push the lubricating ball to contact the lubricating oil in the oil tank at the oil outlet. The lubricating ball rolls and sticks to the lubricating oil to lubricate the rotating ring and the oil tank. After multiple lubrications, the high-pressure spring in the air tank compresses and rebounds to push the lubricating oil close to the oil outlet, thereby avoiding the problem that the amount of lubricating oil stuck to the lubricating ball after multiple lubrications decreases, and the friction between the oil tank and the rotating ring increases. The increased friction will affect the sealing of the device, causing seawater to penetrate into the main body of the monitoring equipment to corrode the monitoring device, affecting the accuracy of the monitoring data, thereby improving the safety of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The outer wall of the drill bit housing 22 is opened with a plurality of nail openings 11.

[0034] In this embodiment: through the reinforcement component that is set, when water flows through the device that has been inserted into the landslide, the rotation of the turbine 2 drives the screw rod 4 to rotate, the rotation of the screw rod 4 drives the rotating rod 6 to move downward, the downward movement of the rotating rod 6 pushes the connecting ring 7 to move downward, the connecting ring 7 drives the rotating shaft 8 and the limiting block 21 to move downward, and when the tip of the fixing nail 10 hits the inner wall of the nail mouth 11, the rotating shaft 8 starts to rotate, and the connecting ring 7 drives the rotating shaft 8 to continue to move downward. The rotating shaft 8 rotates, and the rotation of the rotating shaft 8 drives the fixing nail 10 to rotate, and the fixing nail 10 slowly extends outward through the nail mouth 11 and is inserted into the landslide, thereby avoiding the device being affected by the water flow on the landslide, causing shaking, and then affecting the accuracy of the monitoring data, thereby improving the stability of the device in the landslide, and thereby improving the accuracy of the equipment monitoring data.

[0035] See also Figure 4 and Figure 8 In the figure, the gear assembly includes a gear ring 16 fixedly connected to the inside of the turbine 2, a special-shaped gear 13 is arranged inside the gear ring 16, a plurality of special-shaped grooves 24 are opened on the surface of the special-shaped gear 13, a gear spring 15 is arranged on the surface of the plurality of special-shaped grooves 24, one end of the gear spring 15 is fixedly connected to the special-shaped tooth 14, and the special-shaped gear 13 is hinged to the special-shaped tooth 14.

[0036] In this embodiment: through the gear assembly, when the water flow drives the turbine 2 to rotate counterclockwise, the turbine 2 drives the gear ring 16 to rotate, and when the gear ring 16 engages with the special-shaped teeth 14, the special-shaped teeth 14 shrinks into the special-shaped groove 24, so that the gear ring 16 cannot drive the special-shaped gear 13 to rotate; when the water flow drives the turbine 2 to rotate clockwise, the turbine 2 drives the gear ring 16 to rotate, and the gear ring 16 and the special-shaped teeth 14 complete meshing, the gear ring 16 drives the special-shaped gear 13 to rotate, and the special-shaped gear 13 drives the screw rod 4 to rotate, and the rotation of the screw rod 4 drives the rotating rod 6 to move downward and pushes the connecting ring 7 to move downward, and the nail mouth 11 slowly extends outward and inserts into the landslide during the downward movement of the fixing nail 10, avoiding the problem that the water flow in different directions controls the rotation of the screw rod 4, causing the fixing nail 10 to wander in the nail mouth 11 and cannot be fully inserted into the landslide, thereby improving the reliability of the device.

[0037] Working principle:

[0038] The device is installed vertically on the landslide through the seabed penetration technology. The water flow on the seabed drives the turbine 2 to rotate. When the turbine 2 rotates counterclockwise, the gear ring 16 does not drive the special-shaped gear 13 to rotate, and the teeth of the gear ring 16 mesh with the special-shaped teeth 14. The special-shaped teeth 14 shrink into the special-shaped groove 24 and compress the gear spring 15. After the special-shaped teeth 14 pass through the teeth of a gear ring 16, the gear spring 15 compresses and rebounds to push the special-shaped teeth 14 back to their original positions; when the turbine 2 rotates clockwise, the gear ring 16 meshes with the special-shaped teeth 14, and the gear ring 16 drives the special-shaped teeth 14 to rotate. The movable special-shaped gear 13 rotates, and the rotation of the special-shaped gear 13 drives the screw rod 4 to rotate. The rotation of the screw rod 4 causes the rotating ring 5 to move downward through the thread, and the rotating ring 5 drives the rotating rod 6 to move downward. In the process of the rotating rod 6 pushing the connecting ring 7 to move downward, the connecting ring 7 drives the rotating shaft 8 to move downward and slide in the track groove 32 of the sliding track 12. The fixing nail 10 contacts the inner wall of the nail mouth 11. Through the sliding ball 36, in the process of the connecting ring 7 continuing to move downward, the fixing nail 10 gradually extends outward, and the fixing nail 10 is connected to the rotating shaft 8 and rotates inside the rotating groove block 9.

[0039] When the rotating ring 5 moves to the non-threaded area of ​​the screw rod 4, the fixing nail 10 stops extending, the water flow continues to push the turbine 2 to rotate, the gear ring 16 drives the special-shaped gear 13 to rotate, and the rotation of the special-shaped gear 13 drives the rotating ring 5 to rotate. At this time, the sealing pressure plate 26 and the mechanical seal ring 25 move to the top of the rotating ring 5 through the thread, and the sealing pressure plate 26 squeezes the rubber ring part of the mechanical seal ring 25. The rubber ring part of the mechanical seal ring 25 is squeezed and deformed to both sides. At this time, the mechanical seal ring 25 forms a mechanical seal with the oil tank 19, and the rotating ring 5 continues to rotate with the screw rod 4. When the lubricating ball 17 in the rotating ring 5 rotates to the oil outlet of the oil tank 19, the ball spring 18 in the ball mouth 33 rebounds and pushes the lubricating ball 17 to contact the oil outlet of the oil tank 19, and the connecting ring 7 rolls and sticks the lubricating oil to lubricate the rotating ring 5 and the oil tank 19. After multiple lubrications, the content of the lubricating oil decreases, and the high-pressure spring 30 in the gas tank 28 compresses and rebounds to push the lubricating oil close to the oil outlet.

[0040] Example 2

[0041] See also Figure 4 This embodiment further illustrates Example 1, and the lower end portion of the screw rod 4 in the figure is set to be non-threaded.

[0042] In this embodiment: through the provided screw 4, when the water flow drives the turbine 2 to rotate, and the turbine 2 drives the screw 4 to rotate, so that the rotating ring 5 moves to the non-threaded area of ​​the screw 4, the stopper sliding along the thread groove of the screw 4 in the rotating ring 5 abuts against the end of the thread groove of the screw 4, so that the rotating ring 5 will rotate with the screw 4, ensuring that the rotating ring 5 will no longer move downward through the thread.

[0043] See also Figure 4 and Figure 7 In the figure, the upper end of the drill housing 22 is fixedly connected to the oil tank 19, and an oil groove 23 is provided inside the oil tank 19. The outer wall of the screw rod 4 is threadedly connected to the rotating ring 5, and the rotating ring 5 is rotatably connected to the rotating rod 6. A plurality of ball openings 33 are provided inside the rotating ring 5, and a ball spring 18 is fixedly connected to the surface of the ball opening 33, and an oil-lubricating ball 17 is fixedly connected to one end of the ball spring 18.

[0044] In this embodiment: through the provision of the lubricating ball 17, when the rotating ring 5 reaches the unthreaded area of ​​the screw rod 4 and rotates with the screw rod 4, the lubricating ball 17 is compressed and rebounded by the ball spring 18 in the ball mouth 33 and pushed out, so that the lubricating ball 17 contacts the lubricating oil in the oil groove 23, and sticks to part of the lubricating oil and brings it out to lubricate the rotating ring 5 and the oil tank 19, thereby avoiding excessive friction between the oil tank 19 and the rotating ring 5, causing wear of parts, deteriorating sealing performance, and allowing seawater and substances in seawater to enter, causing corrosion to the monitoring equipment body 1, affecting the normal operation of the monitoring equipment body 1, thereby improving the reliability and safety of the device.

[0045] See also Figure 4 and Figure 5 In the figure, the top of the oil tank 19 is fixedly connected to the gas tank 28, the inside of the gas tank 28 is slidably connected to the piston 29, the top of the piston 29 is fixedly connected to the piston push rod 31, the outer wall of the piston push rod 31 is sleeved with a high-pressure spring 30, the high-pressure spring 30 is placed between the piston 29 and the inner wall of the gas tank 28, the bottom end of the gas tank 28 is provided with a first connecting port 34, the top end of the oil tank 19 is provided with a second connecting port 35, and the first connecting port 34 is aligned with the second connecting port 35.

[0046] In this embodiment: through the provided air tank 28, when the rotating ring 5 moves to the unthreaded area of ​​the screw rod 4 and the water flow continues to drive the turbine 2 to rotate, the rotating ring 5 rotates with the turbine 2 through the screw rod 4, and the ball spring 18 inside the ball mouth 33 compresses and rebounds to push the lubricating ball 17 to contact the lubricating oil in the oil tank 19 at the oil outlet, and the lubricating ball 17 rolls and sticks to the lubricating oil to lubricate the rotating ring 5 and the oil tank 19. After multiple lubrications, the high-pressure spring 30 in the air tank 28 compresses and rebounds to push the lubricating oil close to the oil outlet, thereby avoiding the problem that after multiple lubrications, the amount of lubricating oil rolled by the lubricating ball 17 decreases, and the friction between the oil tank 19 and the rotating ring 5 increases. The increased friction will affect the sealing of the device, causing seawater to penetrate into the monitoring equipment body 1 to corrode the monitoring device, affecting the accuracy of the monitoring data, thereby improving the safety of the device.

[0047] Example 3

[0048] See also Figure 4 and Figure 7 In the figure, a mechanical seal ring 25 is arranged above the rotating ring 5, and a sealing pressure plate 26 is arranged above the mechanical seal ring 25. The outer wall of the sealing pressure plate 26 is provided with a protective rod 27, and the protective rod 27 is fixedly connected to one end of the connecting rod 3.

[0049] In this embodiment: through the mechanical sealing ring 25, when the rotating ring 5 moves to the non-threaded area of ​​the screw rod 4 and the water turbine 2 continues to push the turbine 2 to rotate, the sealing pressure plate 26 continues to move downward in a threaded manner and squeezes the mechanical sealing ring 25. The rubber ring part of the mechanical sealing ring 25 is squeezed and deformed to both sides to form a seal, thereby preventing seawater from penetrating into the monitoring equipment body 1 through the gap between the screw rod 4 and the rotating ring 5 to corrode the monitoring device and affect the accuracy of the monitoring data, thereby improving the safety of the device.

[0050] See also Figure 4 In the figure, the radius of the nail opening 11 is greater than the maximum radius of the fixing nail 10.

[0051] In this embodiment, when the rotating ring 5 moves downward, the fixing nail 10 extends outward through the inner wall of the nail opening 11, thereby avoiding the problem that the fixing nail 10 is stuck with the nail opening 11 when being extended obliquely.

[0052] See also Figure 4 and Figure 6 In the figure, a plurality of support rods 20 are fixedly connected between the two connecting rings 7, and the support rods 20 are evenly distributed on the outer wall of the rotating rod 6.

[0053] In this embodiment: by setting the support rod 20, when the rotating ring 5 moves downward and pushes the fixing nails 10 to extend and insert into the landslide, the three groups of fixing nails 10 can be extended at the same time. Compared with extending them one by one, extending them at the same time greatly reduces the working time and enables the fixing to be completed faster.

[0054] See also Figure 3 In the figure, the tip of the fixing nail 10 is rollingly connected with a sliding ball 36.

[0055] In this embodiment, by providing the sliding ball 36 , when the rotating ring 5 moves downward and the fixing nail 10 moves the inner wall of the nail opening 11 , the hard contact between the fixing nail 10 and the nail opening 11 is changed into rolling contact, and the fixing nail 10 extends more smoothly.

[0056] See also Figure 3 and Figure 4 As shown in the figure, the volume inside the gas tank 28 is greater than the volume of the oil tank 23 inside the oil tank 19.

[0057] In this embodiment: when the rotating ring 5 moves to the unthreaded area of ​​the screw rod 4 and the water flow continues to drive the turbine 2 to rotate, the lubricating oil in the oil tank 19 decreases, and the high-pressure spring 30 inside the gas tank 28 pushes the compression rebound to push the piston 29. The piston 29 pushes the gas in the gas tank 28 into the oil tank 19, pushing the lubricating oil close to the oil outlet, avoiding the problem that when the lubricating oil decreases, the lubricating ball 17 rolls on less lubricating oil, which reduces the lubrication ability and affects the wear, thereby improving the reliability of the device.
