Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of environmental survey devices, specifically a corrosion environment survey device and survey method for a direct-buried gas pipeline crossing a strait. Background Technology
[0002] Direct-buried gas pipelines crossing straits are a special type of pipeline facility, mainly used for transporting natural gas. Due to their special geographical location crossing straits, they need to face more complex environmental conditions and higher safety requirements.
[0003] To ensure the safe operation of directly buried gas pipelines crossing straits, it is necessary to strengthen the construction of monitoring and early warning systems. This includes real-time monitoring of the seabed topography, water flow velocity, and water quality composition around the pipeline, as well as monitoring and early warning of the pipeline's own temperature, pressure, and leakage. Through these measures, potential safety hazards can be detected in a timely manner, and corresponding countermeasures can be taken. Conducting corrosion environment surveys on directly buried gas pipelines crossing straits is of great significance for ensuring the safe and stable operation of the pipelines, and helps to improve operational efficiency, prevent environmental pollution, and safeguard social stability.
[0004] Common corrosion environment survey devices for directly buried gas pipelines crossing straits include corrosion rate detectors, electrochemical detection instruments, probe-type corrosion detectors, corrosion environment analysis instruments, and optical coherence vibrometers. Among these, the optical coherence vibrometer is an instrument that measures the vibration of an object using the principle of optical interference. Its working principle involves splitting a laser beam into two beams: one serves as a reference beam, and the other, after passing through the object under test, is reflected back and interferes with the reference beam to form interference fringes. By measuring the changes in these interference fringes, the vibration of the object can be analyzed. In corrosion environment surveys of directly buried gas pipelines crossing straits, the optical coherence vibrometer can accurately measure the pipeline's vibration, understand its stress distribution, fatigue damage, and potential corrosion areas. By analyzing this data, the safety status of the pipeline can be assessed, and potential problems can be identified and addressed promptly. Furthermore, this non-contact measurement method does not damage the pipeline and has high practical value.
[0005] Currently, optical coherent vibration meters are generally used outdoors for corrosion environment surveys of directly buried gas pipelines crossing straits. Therefore, they are mostly powered by batteries. However, due to problems such as excessive output current during battery use, leakage may occur. Using leaking batteries may damage the instrument and affect the results of the corrosion environment survey. Summary of the Invention

[0011] As a further technical solution of the present invention, the mounting plate is slidably installed inside the vibration meter body, and a third spring is connected between the mounting plate and the vibration meter body.
[0012] As a further technical solution of the present invention, the connecting component includes a second handle that is slidably installed inside the battery cover, and a connecting block is fixedly connected to one end of the second handle.

The first slider is slidably installed inside the support plate, and a first spring is installed on one side of the first slider.
[0016] A survey method for a corrosion environment survey device used for a directly buried gas pipeline crossing a strait includes the following steps: S1: Connect the control device and the vibration meter body via a connecting cable; S2: First, press and hold the first handle to pull the light shield outward, so that the mounting rod is pulled out of the vibration meter body; S3: When the mounting rod is pulled out of the vibration meter body and completely separated from the moving rod, the elastic potential energy released by the second spring pushes the first connecting plate to move to one side. The movement of the first connecting plate drives the movement of the second connecting plate, and the movement of the second connecting plate drives the movement of the protrusion and the push block. S4: The protrusion moves and separates from the moving block. The third spring releases elastic potential energy to pull the mounting plate upward. The movement of the mounting plate drives the movement of the cleaning cotton, causing the cleaning cotton to separate from the battery body. S5: Simultaneously, the pusher moves and separates from the tray. The fifth spring releases its elastic potential energy to push the second slider to one side. The movement of the second slider drives the movement of the tray. The movement of the tray drives the battery body to move towards the conductive contact to facilitate the connection between the two, power the device, and conduct testing.
[0017] The beneficial effects of this invention are as follows: 1. This invention, through the design of a movable component, allows for the following steps after use: First, the light-shielding plate is flipped upwards. Then, the mounting rod is inserted into the vibratory meter body, causing the mounting rod to move inward against the movable rod. The movement of the movable rod drives the movement of the first connecting plate, which in turn drives the movement of the second connecting plate. The movement of the second connecting plate then drives the movement of the push block, which in turn pushes the support plate away from the conductive contact. This movement of the support plate further drives the movement of the battery body, separating it from the conductive contact. This avoids the common problem in current optical coherence vibratory meters used for corrosion environment surveys of buried gas pipelines crossing straits, which are typically operated outdoors and powered by batteries. Due to issues such as excessive current output from the batteries, leakage can occur during use. Using leaking batteries can damage the instrument and affect the results of corrosion environment surveys. This device separates the battery body from the conductive contact when not in use for corrosion environment surveys, reducing the impact of battery leakage on the instrument. Furthermore, the leaking liquid can be absorbed by cleaning cotton, improving the protection of the equipment and ensuring its stability during use.
[0018] 2. This invention, through the provision of a cleaning cotton, allows the second connecting plate to move towards one side of the battery body. This movement of the second connecting plate causes the protrusion to move, and the protrusion contacts the moving block, pushing the moving block downwards. The downward movement of the moving block then causes the mounting plate to move downwards, which in turn causes the cleaning cotton to move downwards, bringing it between the conductive contact and the battery body and into contact with one side of the battery body. This not only wipes the contact surface between the battery body and the conductive contact, improving the sensitivity of their connection, but also absorbs any leakage from the battery body, preventing corrosion and damage to the equipment's appearance and internal structure, thus improving the equipment's safety and lifespan.
[0019] 3. By setting up the connecting components, when the battery body needs maintenance, first press down on the second handle, the second handle drives the fourth spring to move downward, the fourth spring moves downward and drives the connecting block to move downward, then pull the second handle outward to pull the connecting block out of the vibration meter body, and finally rotate the battery cover downward to expose the internal cavity of the vibration meter body, making it easy to take out the battery body for maintenance.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example 1 like Figures 1 to 12As shown in the embodiment of the present invention, a corrosion environment investigation device for a direct-buried gas pipeline crossing a strait includes a control device 1. A vibration meter body 2 is provided on one side of the control device 1. A bracket 3 is installed at the bottom of the vibration meter body 2. A laser head 4 is fixedly installed on one side of the vibration meter body 2. A protective component is provided on one side of the laser head 4. A conductive contact plate 12 is fixedly installed inside the vibration meter body 2. A battery body 11 is provided on one side of the conductive contact plate 12. The battery body 11 is installed inside the vibration meter body 2 through a moving component. A battery cover 9 is provided on the side of the battery body 11 away from the conductive contact plate 12. The battery cover 9 is rotatably installed on one side of the vibration meter body 2. A connecting component is installed between the battery cover 9 and the vibration meter body 2. The protective components include a light shield 5 set on one side of the laser head 4, a connecting rope 6 fixedly connected to one side of the light shield 5, the end of the connecting rope 6 away from the light shield 5 fixedly installed on the side wall of the vibration meter body 2, a first handle 7 fixedly installed on one side of the light shield 5, and an installation rod 8 fixedly connected to the top of the first handle 7, the installation rod 8 being embedded inside the vibration meter body 2. The movable component includes a support plate 13 disposed at the bottom of the battery body 11. A first baffle 14 and a second baffle 15 are respectively disposed on both sides of the support plate 13. The first baffle 14 is fixedly installed on the top of the support plate 13, and the second baffle 15 is slidably installed inside the support plate 13. A push block 28 is disposed on one side of the first baffle 14. There are two push blocks 28, and both push blocks 28 are fixedly installed on one side of the second connecting plate 22. A first connecting plate 20 is fixedly installed on the top of the two second connecting plates 22. A moving rod 19 is fixedly connected to one side of the first connecting plate 20 and is slidably installed inside the vibration meter body 2.
[0024] By configuring the moving components, after using the equipment, firstly, the light-shielding plate 5 is flipped upwards, and then the mounting rod 8 is embedded inside the vibration meter body 2. The mounting rod 8 then moves inwards against the moving rod 19. The movement of the moving rod 19 drives the movement of the first connecting plate 20, which in turn drives the movement of the second connecting plate 22. The movement of the second connecting plate 22 drives the movement of the push block 28, which in turn pushes the support plate 13 to move away from the conductive contact plate 12. This movement of the support plate 13 then drives the movement of the battery body 11, separating the battery body 11 from the conductive contact plate 12, thus avoiding the problems encountered by current optical coherent vibration meters. In corrosion environment surveys of directly buried gas pipelines crossing straits, which are generally conducted outdoors, batteries are often used for power. However, due to issues such as excessive current output during battery use, leakage may occur. Using leaking batteries can damage the instrument and affect the results of the corrosion environment survey. When the device is not in use for corrosion environment surveys, the battery body 11 is separated from the conductive contact 12 to reduce the impact of battery leakage on the instrument. Furthermore, the leaking liquid can be absorbed by the cleaning cotton 35, improving the protection of the equipment and ensuring its stability during use.
[0025] like Figures 1 to 12 As shown, a second slider 31 is fixedly installed at the bottom of the support plate 13. The second slider 31 is slidably installed inside the vibration meter body 2. A fifth spring 32 is provided on one side of the second slider 31.
[0026] When the support plate 13 slides outward, the movement of the support plate 13 drives the movement of the second slider 31. The second slider 31 compresses and deforms the fifth spring 32 to store elastic potential energy. When the protrusion 23 and the moving block 24 separate, the elastic potential energy is released through the fifth spring 32 to push the second slider 31 to move and reset the support plate 13.
[0027] like Figures 1 to 12 As shown, the first connecting plate 20 is slidably installed inside the vibration meter body 2, and a second spring 21 is connected between the first connecting plate 20 and the vibration meter body 2.
[0028] When the first connecting plate 20 moves, the first connecting plate 20 compresses the second spring 21, causing the second spring 21 to deform and store elastic potential energy. When the equipment is needed, first pull the first handle 7 to pull the light shield 5 outward, so that the mounting rod 8 is pulled out of the vibration meter body 2. After the mounting rod 8 is pulled out of the vibration meter body 2, it is completely separated from the moving rod 19. The second spring 21 releases elastic potential energy to push the first connecting plate 20 to one side. Similarly, the support plate 13 carries the battery body 11 and moves it closer to the conductive contact plate 12, so that the two can be connected for use.
[0029] like Figures 1 to 12 As shown, protrusions 23 are fixedly installed on one side of each of the two second connecting plates 22. Movable blocks 24 are provided at the ends of the two protrusions 23 away from the second connecting plates 22. Both movable blocks 24 are installed on the top of the mounting plate 25. Hook teeth 26 are evenly installed on the side wall of the mounting plate 25. Cleaning cotton 35 is installed on the side wall of the hook teeth 26.
[0030] The side of the movable block 24 near the protrusion 23 is set as an inclined surface, and the inside of the vibration meter body 2 is provided with a sliding groove for the movable block 24 to slide up and down; When the second connecting plate 22 moves toward one side of the battery body 11, the movement of the second connecting plate 22 drives the movement of the protrusion 23. The protrusion 23 contacts the moving block 24 and pushes the moving block 24 downward. The downward movement of the moving block 24 drives the mounting plate 25 downward. The downward movement of the mounting plate 25 drives the cleaning cotton 35 downward, so that the cleaning cotton 35 moves between the conductive contact 12 and the battery body 11 and contacts one side of the battery body 11. This not only wipes the contact surface between the battery body 11 and the conductive contact 12, improving the sensitivity when the two are connected, but also absorbs the leakage of the battery body 11, preventing the battery leakage from corroding the equipment, damaging the appearance and internal structure of the equipment, and improving the safety and service life of the equipment.
[0031] With the hook teeth 26 in place, when the cleaning cotton 35 needs to be replaced, first rotate the battery cover 9 downwards through the connecting component, then remove the battery body 11, and finally pull the cleaning cotton 35 outwards to separate the cleaning cotton 35 from the hook teeth 26, making it easy to replace the cleaning cotton 35.
[0032] like Figures 1 to 12 As shown, the mounting plate 25 is slidably installed inside the vibration meter body 2, and a third spring 27 is connected between the mounting plate 25 and the vibration meter body 2.
[0033] The top end of the mounting plate 25 is fixedly connected to the bottom end of the third spring 27, and the top end of the third spring 27 is fixedly connected to the inner wall of the vibration meter body 2. When the mounting plate 25 moves downward, the mounting plate 25 pulls the third spring 27 to deform and store elastic potential energy. When the protrusion 23 separates from the moving block 24, the elastic potential energy can be released through the third spring 27 to pull the mounting plate 25 upward. Similarly, the movement of the mounting plate 25 drives the movement of the cleaning cotton 35, so that the cleaning cotton 35 is moved away from one side of the battery body 11 and separated from it, so that the battery body 11 can be connected to the conductive contact 12 for use.
[0034] like Figures 1 to 12 As shown, the connecting assembly includes a second handle 10 that is slidably installed inside the battery cover 9. One end of the second handle 10 is fixedly connected to a connecting block 30, which is embedded inside the vibration meter body 2.
[0035] By setting up the connecting components, when maintenance of the battery body 11 is required, first press down on the second handle 10. The second handle 10 drives the fourth spring 29 to move downward. The fourth spring 29 moves downward, which in turn drives the connecting block 30 to move downward. Then, pull the second handle 10 outward to pull the connecting block 30 out of the vibration meter body 2. Finally, rotate the battery cover 9 downward to expose the internal chamber of the vibration meter body 2, making it easier to remove the battery body 11 for maintenance.
[0036] like Figures 1 to 12 As shown, a fourth spring 29 is provided at the bottom of the second handle 10, and the fourth spring 29 is installed inside the battery cover 9.
[0037] One side of the connecting block 30 is set as an inclined surface. When it is necessary to install the battery cover 9 on one side of the vibration meter body 2, pull the second handle 10 to push one side of the vibration meter body 2. The movement of the second handle 10 drives the movement of the connecting block 30. When the inclined surface of the connecting block 30 contacts the vibration meter body 2, the connecting block 30 is squeezed and moves downward. At the same time, the movement of the connecting block 30 causes the fourth spring 29 to deform and store elastic potential energy. When the connecting block 30 slides into the vibration meter body 2, the elastic potential energy is released through the fourth spring 29, so that the connecting block 30 is stuck inside the vibration meter body 2, which makes it easy to install the battery cover 9 on the side wall of the vibration meter body 2.
[0038] like Figures 1 to 12 As shown, a limiting plate 33 is provided at the bottom of the second baffle 15. The limiting plate 33 is slidably installed inside the vibration meter body 2. A sixth spring 34 is installed at the bottom of the limiting plate 33.
[0039] When it is necessary to remove the battery body 11 from the vibration meter body 2, firstly, the inside of the vibration meter body 2 is opened by rotating the battery cover 9. Then, the second baffle 15 is pressed down. The second baffle 15 moves down and drives the limiting plate 33 to move down. The limiting plate 33 compresses the sixth spring 34. At the same time, the second baffle 15 slides down inside the support plate 13 until it is level with the surface of the support plate 13. Then, the battery body 11 is removed.
[0040] like Figures 1 to 12 As shown, a push plate 16 is provided on one side of the first baffle 14, and a first slider 17 is fixedly installed at the bottom end of the push plate 16. The first slider 17 is slidably installed inside the support plate 13, and a first spring 18 is installed on one side of the first slider 17.
[0041] When the second baffle 15 is pressed down, the elastic potential energy released by the first spring 18 can pull the first slider 17 to move away from the conductive contact 12. The movement of the first slider 17 drives the movement of the push plate 16. The movement of the push plate 16 pushes the battery body 11 to slide outward, making it easier for staff to remove it. This prevents the problem that the cavity inside the vibration meter body 2 is too small, making it inconvenient for staff to pull out the battery body 11 by hand, and improves the convenience of staff to remove the battery body 11.
[0042] A survey method for a corrosion environment survey device used for a directly buried gas pipeline crossing a strait includes the following steps: S1: Connect the control device 1 and the vibration meter body 2 via a connecting cable; S2: First, press and hold the first handle 7 to pull the light shield 5 outward, so that the mounting rod 8 is pulled out of the vibration meter body 2; S3: When the mounting rod 8 is pulled out of the vibration meter body 2 and completely separated from the moving rod 19, the elastic potential energy released by the second spring 21 pushes the first connecting plate 20 to one side. The movement of the first connecting plate 20 drives the movement of the second connecting plate 22. The movement of the second connecting plate 22 drives the movement of the protrusion 23 and the push block 28. S4: The protrusion 23 moves and separates from the moving block 24. The third spring 27 releases elastic potential energy to pull the mounting plate 25 upward. The movement of the mounting plate 25 drives the movement of the cleaning cotton 35, causing the cleaning cotton 35 to separate from the battery body 11. S5: At the same time, the push block 28 moves and separates from the tray 13. The fifth spring 32 releases elastic potential energy to push the second slider 31 to one side. The movement of the second slider 31 drives the movement of the tray 13. The movement of the tray 13 drives the battery body 11 to move to one side of the conductive contact piece 12, so that the two can be connected to supply power to the equipment for testing.
[0043] Working principle and usage process: When it is necessary to use the instrument to investigate the corrosive environment, first press the first handle 7 and pull the light shield 5 outward so that the mounting rod 8 is pulled out of the vibration meter body 2. After the mounting rod 8 is pulled out of the vibration meter body 2, it is completely separated from the moving rod 19. The elastic potential energy released by the second spring 21 pushes the first connecting plate 20 to one side. The movement of the first connecting plate 20 drives the movement of the second connecting plate 22. The movement of the second connecting plate 22 drives the movement of the protrusion 23 and the push block 28. The protrusion 23 moves and separates from the moving block 24. The third spring 27 releases its elastic potential energy, pulling the mounting plate 25 upward. The movement of the mounting plate 25 causes the cleaning cotton 35 to move, separating the cleaning cotton 35 from the battery body 11. At the same time, the pusher 28 moves and separates from the support plate 13. The fifth spring 32 releases elastic potential energy to push the second slider 31 to one side. The movement of the second slider 31 drives the support plate 13 to move. The movement of the support plate 13 drives the battery body 11 to move to one side of the conductive contact plate 12, so that the two can be connected to supply power to the equipment for testing.
[0044] After using the equipment, first flip the light shield 5 upward so that the mounting rod 8 is embedded inside the vibration meter body 2. The mounting rod 8 moves inward against the moving rod 19. The movement of the moving rod 19 drives the movement of the first connecting plate 20. The movement of the first connecting plate 20 drives the movement of the second connecting plate 22. The movement of the second connecting plate 22 drives the movement of the protrusion 23 and the push block 28. The protrusion 23 moves and pushes the moving block 24 to move downward. The moving block 24 moves downward and drives the mounting plate 25 to move downward. The moving plate 25 moves downward and drives the cleaning cotton 35 to move downward, so that the cleaning cotton 35 moves to one side of the battery body 11. At the same time, the movement of the pusher 28 pushes the movement of the tray 13, and the movement of the tray 13 drives the movement of the battery body 11, causing the battery body 11 to separate from the conductive contact 12.
[0045] When it is necessary to replace the battery body 11, first press down on the second handle 10. The movement of the second handle 10 compresses and stores elastic potential energy in the fourth spring 29, and drives the fourth spring 29 to move downward. Then pull the second handle 10 outward to pull the connecting block 30 out of the vibration meter body 2. Then rotate the battery cover 9 downward to facilitate the removal of the battery body 11 for replacement.
[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
