[0002] In offshore oil exploitation and other offshore operations, underwater equipment is required. As underwater equipment is in the seawater environment for a long time, it is susceptible to corrosion, which will affect the normal operation of the underwater equipment. Therefore, it is necessary to use corrosion data detection devices to timely detect the location and degree of corrosion of underwater equipment, so as to facilitate timely maintenance in the later stage and avoid major losses;

[0003] The patent name disclosed by the announcement number "CN209764683U" in the prior art is "A underwater equipment oxidation corrosion data detection device", which discloses that the underwater corrosion data detection device includes a sensor probe, an AM data expansion board, a data collector, a data storage unit and a power supply unit, a plurality of the sensor probes are arranged on the underwater equipment, the input end of the AM data expansion board is connected to the plurality of sensor probes, and its output end is connected to the input end of the data collector; the input end of the data storage unit is connected to the output end of the data collector, and the power supply unit supplies power to the underwater corrosion data detection device, the surface data processing system includes a computer processor and a permanent data storage unit, the input end of the computer processor is connected to the output end of the data storage unit by a communication optical cable, and the output end of the computer processor is connected to the input end of the permanent data storage unit, and the various data analyzed are stored in the permanent data storage unit, so as to effectively realize the underwater equipment oxidation corrosion data detection, and the signal output by the sensor can be regularly collected and stored, and the long-term data detection can be completed by continuous work, so as to provide a large amount of data support for analyzing the oxidation corrosion state and studying protection;

[0004] The patent name disclosed by the announcement number "CN109406377A" in the prior art is "A Hydrogen Sulfide Corrosion Data Detection Device for Underwater Equipment", which discloses a data processor, which is connected to a data receiver through a communication optical cable, receives the hydrogen sulfide concentration data and its position code detected by each hydrogen sulfide concentration detector, and converts them into concentration electrical signals and corresponding position electrical signals for output respectively, and a computer processor, which is connected to the data processor through a signal line, receives and processes the concentration electrical signals and position electrical signals output by the data processor, and sets hydrogen sulfide concentration detectors at key positions and key areas that need to be detected, such as oil and gas transmission pipelines and trunk pipelines of underwater equipment, so as to detect whether hydrogen sulfide leaks and the extent of leakage in real time, so as to achieve timely warning and timely intervention to prevent the occurrence of major safety accidents.

[0005] The above-mentioned underwater equipment corrosion data detection device, when in use, directly installs the hydrogen sulfide concentration detector at various positions of the underwater equipment for detection work, so that the hydrogen sulfide concentration detector is directly exposed to seawater. Since the specific heat capacity of seawater is large, the temperature of seawater is relatively stable regardless of summer or winter, which will make the seawater always in a low temperature state. The long-term use of the hydrogen sulfide concentration detector in a low temperature environment will affect the sensitivity and response time of the hydrogen sulfide concentration detector. Therefore, when the corrosion data detection device detects severe corrosion, it cannot give a timely warning, thereby affecting the corrosion data detection work;

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0051] A suspension ring 201 is installed on the upper surface of the protection frame 2, two rows of suspension rods 8 are installed on the bottom surface of the detection shell 1, and a suspension ring 201 is sleeved on the outer side of one end of the suspension rod 8. The computer terminal 5 includes a data processing and analysis module, a data display module and a data storage module. The automatic drive component includes a drive column 9 rotatably installed on the bottom surface of the protection frame 2, and a water wheel mechanism 91 installed on the outer side of the drive column 9. The interior of the drive column 9 is connected to the outer side of the lower end of the hydrogen sulfide concentration detector 3 through a sealed bearing. A transmission column 10 and a vertical rod 12 are installed throughout the interior of the protection frame 2. The vertical rod 12 is set on the right side of the transmission column 10, and the drive column 9 is set on the left side of the transmission column 10. The upper outer side of the drive column 9, the outer side of the transmission column 10 and the lower outer side of the vertical rod 12 are all installed with a transmission gear 11. The three groups The transmission gear 11 is meshed and connected, and a protective main shell 7 is arranged on the outer side of the water wheel mechanism 91. An upper shell 72 is installed above the protective main shell 7 through a sealed bearing. The upper end of the upper shell 72 is connected to the bottom surface of the protective frame 2 through a mounting rod 73. The middle inner parts of the protective main shell 7 and the upper shell 72 are grooved and rotatably connected with a driving column 9 through a sealed bearing. A drain pipe 74 is installed below the protective main shell 7. The automatic heat generating component includes a first heat generating block 13 installed above the vertical rod 12 in the protective frame 2, and also includes a second heat generating block 14 installed in the protective frame 2. The second heat generating block 14 is tightly connected to the first heat generating block 13. The second heat generating block 14 and the first heat generating block 13 are both arranged in a circular structure, and the second heat generating block 14 and the first heat generating block 13 are both made of copper.

[0052] A regulating installation column 15 with a hollow structure is installed inside the protective frame 2, a limiting cross bar 152 is installed inside the lower part of the regulating installation column 15, a regulating spring 151 is fixed inside the upper part of the regulating installation column 15, a boss 141 is installed above the second heat generating block 14, a through groove 142 is opened inside the boss 141, the upper part of the boss 141 is inserted into the regulating installation column 15, the upper part of the boss 141 is connected to the regulating spring 151, and the limiting cross bar 152 is set through the through groove 142.

[0053] First, the entire underwater equipment corrosion data detection device is moved into the working area. After arriving at the working area, the detection shell 1 is installed next to the underwater equipment on the seabed. Then, the multiple protection frames 2 suspended on the suspension rod 8 at the bottom of the detection shell 1 are taken down through the suspension ring 201. The multiple protection frames 2 are installed in various positions of the underwater equipment in turn. Then, the hydrogen sulfide concentration detector 3 in the protection frame 2 detects the hydrogen sulfide concentration around the underwater equipment in real time. Then, the hydrogen sulfide concentration detector 3 transmits this signal to the data receiver 16 in the detection shell 1. The data receiver 16 then transmits this signal to the computer terminal 5 through the communication optical cable 4. The data is analyzed and processed by the data processing and analysis module in the computer terminal 5. This is used to determine whether hydrogen sulfide has leaked and the extent of the leakage, and to provide data support for analyzing the corrosion state of underwater equipment. At the same time, the data is stored through the data storage unit, and the content displayed by the data storage module can be viewed through the display screen in the computer terminal 5. When the computer terminal 5 analyzes that the extent of hydrogen sulfide leakage is large, this will cause the surface of the underwater equipment to be corroded to a large extent. At this time, the computer terminal 5 controls the alarm 6 to sound an alarm to remind the staff. (A corrosion potential sensor, a corrosion current sensor or a temperature sensor can also be installed under the protection frame 2 to enhance the diversity of data collection and facilitate the detection of corrosion data of underwater equipment. Since this part is a prior art, it will not be introduced in detail here).

[0054] After the protection frame 2 is installed, the position of the water collecting pipe 71 can be adjusted by rotating the protection main shell 7, so that the water collecting pipe 71 faces the direction of the water flow. At this time, the water flow can enter the protection main shell 7 through the water collecting pipe 71, so that the flow energy of the seawater automatically drives the water wheel mechanism 91 in the automatic drive component to rotate. At this time, the water wheel mechanism 91 drives the driving column 9 to rotate. The driving column 9 is connected by the meshing of three sets of transmission gears 11 to drive the vertical rod 12 to rotate. At this time, the vertical rod 12 drives the first heat generating block 13 to rotate. At this time, the first heat generating block 13 generates friction with the bottom surface of the second heat generating block 14 when rotating, so that The first heat generating block 13 and the second heat generating block 14 generate heat by friction, which is convenient for heating the temperature inside the protection frame 2, so as to avoid the low temperature inside the protection frame 2 affecting the sensitivity and response time of the hydrogen sulfide concentration detector 3, so that the corrosion data detection device can respond quickly and give timely warnings to emergencies. (Since the specific heat capacity of seawater is large, the temperature of seawater is relatively stable regardless of summer or winter, so that the seawater is always in a low temperature state. At the same time, the seawater is fluid, so the first heat generating block 13 and the second heat generating block 14 continuously generate heat by friction, and the temperature inside the protection frame 2 will not be too high).

[0055] The regulating spring 151 in the regulating installation column 15 can always apply a pressure to the second heat generating block 14, so that the second heat generating block 14 is in close contact with the first heat generating block 13. At the same time, the interior of the driving column 9 below the protective frame 2 is hollow, and the interior of the driving column 9 is connected to the lower outer side of the hydrogen sulfide concentration detector 3 through a sealed bearing, so that the driving column 9 can shield and protect the lower outer part of the hydrogen sulfide concentration detector 3, thereby reducing the impact force of seawater on the lower outer part of the hydrogen sulfide concentration detector 3.

[0056] Embodiment 2: The underwater equipment corrosion data detection device for timely warning in this embodiment can adjust the temperature in the detection housing 1 on the basis of embodiment 1 to avoid the low temperature in the detection housing 1 affecting the service life of the data receiver 16 and the battery module 17. For the specific structure, refer to the attached Figure 9-11As shown, an automatic driving component is also installed on the outside of the detection shell 1, and an automatic heat generating component is also installed inside the detection shell 1. Similarly, as shown in Example 1, an automatic driving component is installed on the outer side of the detection shell 1, and an automatic heat generating component is installed inside the detection shell 1, so that seawater can enter the protective main shell 7 outside the detection shell 1, driving the water wheel mechanism 91 and the driving column 9 in the protective main shell 7 to rotate. The driving column 9 drives the vertical rod 12 in the detection shell 1 to rotate through the cooperation of three sets of transmission gears 11. The vertical rod 12 drives the first heat generating block 13 to rotate, so that the automatic heat generating component in the detection shell 1 generates heat to heat the inside of the detection shell 1, so as to avoid the data receiver 16 and the battery module 17 in the detection shell 1 from being used for a long time in a low temperature environment and thus reducing the lifespan. The driving column 9 installed on the outside of the detection shell 1 is solid.

[0057] Embodiment 3: The underwater equipment corrosion data detection device for timely warning in this embodiment can also use the flow energy of seawater to generate electricity on the basis of embodiment 2 to provide electrical energy for the use of the corrosion data detection device. For specific structure, refer to the attached Figure 10-11 As shown, a generator 18 and a rectifier 19 are installed on the right side inside the detection shell 1. The rectifier 19 is connected to the lower rear side of the generator 18. The rectifier 19 is connected to the battery module 17. The outer side of the vertical rod 12 in the detection shell 1 is connected to the shaft end of the generator 18 through a bevel gear. When the vertical rod 12 in the detection shell 1 rotates, the outer side of the vertical rod 12 drives the output shaft end of the generator 18 to rotate through the bevel gear set. When the output shaft end of the generator 18 rotates, electrical energy is generated, and then the generated electrical energy is stored in the battery module 17 through the rectifier 19, so as to provide electrical energy to the corrosion data detection device of the underwater equipment in the later stage.
