[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention is described clearly and completely below. Obviously, the described embodiments are 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 persons in the art without creative work are within the scope of protection of the present invention.

[0037] In order to gain an in-depth understanding of the ocean dynamic environment of the South China Sea, it is particularly important to master the statistical laws and distribution characteristics of environmental parameters such as waves, currents, internal waves, etc. in the sea area, especially the production and propagation laws of internal waves in the northern shelf area of ​​the South China Sea. Long-term marine environmental monitoring is required to provide basic data for deep-water marine oil development in the South China Sea. In view of the above technical problems, the present invention provides an offshore oil platform environmental parameter monitoring system, which can help grasp the statistical laws and distribution characteristics of environmental parameters such as waves, currents, internal waves, etc. in the current sea area. The technical solution of the present invention is described in detail below in conjunction with specific examples.

[0038] Reference Figure 1 As shown, the present invention relates to an offshore oil platform environmental parameter monitoring system, comprising a winch drive device, a composite cable, a current monitoring device and a counterweight. The winch drive device is arranged on the offshore platform, the composite cable is wound and connected to the winch drive device, and the winch drive device is used to retract and release the composite cable.

[0039] The ocean current monitoring device is connected to the composite cable. The ocean current monitoring device includes an ocean current meter. The ocean current meter is used to monitor environmental parameters of the sea area. The environmental parameters specifically include the speed and direction of water flow in the ocean. The counterweight is connected to the ocean current meter.

[0040] The present invention is based on the installation of an offshore platform and a winch drive device. The equipment on the offshore platform provides power to the current monitoring device through a composite cable, and the monitoring data of the current meter is instantly transmitted to the platform through the composite cable for subsequent further data processing, including database storage, real-time data display, email transmission to a land terminal, etc. Monitoring with a cabled buoy can ensure the safety of the equipment, and can obtain monitoring element data in a timely manner, which is conducive to data analysis and processing. It can provide real-time marine environmental data and related reminders for oil and gas development platforms.

[0041] In one embodiment, it is more preferable that, in order to protect the current meter, the current monitoring device further includes a protection cage, the current meter is arranged inside the protection cage, the protection cage is load-bearingly connected to the composite cable, and the current meter is electrically connected to the composite cable.

[0042] In this embodiment, the counterweight is load-bearingly connected to the bottom of the protection cage.

[0043] The setting of the counterweight allows the composite cable and the entire current monitoring device to be fixed vertically underwater, improving the data feedback stability of the monitoring system and making subsequent research results more accurate.

[0044] In one embodiment, more preferably, the monitoring system further includes a temperature-salinity measuring instrument, which is disposed above the current meter and is electrically connected to the composite cable.

[0045] Temperature and salinity measuring instruments are mainly used to measure the temperature and salinity of ocean water bodies. These parameters are key data in the fields of marine science research, environmental monitoring, climate change research and hydrological engineering. The following are several common temperature and salinity measuring instruments and their characteristics:

[0046] 1.CTD sensor

[0047] CTD stands for Conductivity, Temperature and Depth. CTD instruments are commonly used in ocean exploration and can simultaneously measure the temperature, conductivity and pressure of water bodies to infer salinity.

[0048] How it works: Conductivity is directly proportional to the salinity of water, so by measuring the conductivity of a body of water, the salinity can be calculated.

[0049] 2. Salinity meter

[0050] A salinometer is an instrument specifically used to measure the salinity of water.

[0051] type:

[0052] Conductivity Salinometer: Estimates salinity by measuring the electrical conductivity of water.

[0053] Optical salinity meter: uses the principle of light refraction for measurement.

[0054] 3. Thermometer

[0055] An instrument designed specifically to measure water temperature, which can be a digital thermometer or a traditional liquid-based thermometer.

[0056] Sensor Type: Use a thermistor, thermocouple, or infrared sensor, etc.

[0057] 4. Multi-parameter water quality monitor

[0058] These instruments can measure multiple water quality parameters simultaneously, including temperature, salinity, pH, dissolved oxygen, and more.

[0059] In this embodiment, two temperature-salinity measuring instruments are arranged vertically at intervals. The interval arrangement of the two temperature-salinity measuring instruments can play a role in mutual verification. During the monitoring process, if the monitoring values ​​between the two temperature-salinity measuring instruments differ greatly, it means that one of the temperature-salinity measuring instruments has a fault. This optimized setting can facilitate the staff to understand the situation of the underwater equipment and enable the staff to make necessary adjustments to the on-site equipment in a timely manner.

[0060] Reference Figure 1 , Figure 2 as well as Figure 3As shown, in one embodiment, the overall structure of the winch drive device is further refined, and the winch drive device includes an electric winch and a load-bearing bracket, wherein the composite cable is connected to the electric winch. The load-bearing bracket is arranged at the edge of the offshore platform, and a wire pulley is rotatably connected to the load-bearing bracket, the wire pulley is for the composite cable to be sunk and installed, and the load-bearing bracket is used to bear and support the wire pulley.

[0061] Specifically, the load-bearing bracket includes a main pole and a main support pole. The main pole is tilted, one end of the main pole is fixed to the offshore platform through a fixing seat, and the other end is connected to the guide wheel for rotation. The main support pole is vertically arranged, the top is connected to the middle of the main pole, and the bottom is fixedly connected to the offshore platform.

[0062] In this embodiment, it is more preferred that the load-bearing bracket also includes an auxiliary support rod, one end of which is connected to the main rod, and the other end of which extends downward and away from the main rod, and the end is fixedly connected to the offshore platform.

[0063] It should be noted that the guide wheel is rotatably connected to the main rod on one side of the auxiliary support rod, and the auxiliary support rod extends outwardly to optimize the overall stress state of the main rod and provide auxiliary support for the main rod and the guide wheel.

[0064] In one embodiment, the offshore oil platform environmental parameter monitoring system is specifically used to measure environmental parameters of sea areas with different depths and currents within a sea depth of 200m, so in this embodiment, the weight of the counterweight is set at 2t-2.5t, and is specifically set to 2t.

[0065] The current meter is an acoustic Doppler current meter. It uses the Doppler effect of sound waves to measure the water velocity at different depths. This device can provide high-precision flow velocity data and can work in complex water conditions.

[0066] During the monitoring process, the composite cable is retracted and released by controlling the electric winch, thereby controlling the specific depth of the current meter, and adjusting different depths within 200m of the sea water depth for monitoring as needed. The present invention is installed on an offshore platform and a winch drive device. The equipment on the offshore platform provides power to the current monitoring device through a composite cable, and transmits the monitoring data of the current meter to the platform in real time through the composite cable for subsequent further data processing, including database storage, real-time data display, and email transmission to land terminals. Monitoring with a cabled buoy can ensure the safety of the equipment, and at the same time can obtain monitoring element data in a timely manner, which is conducive to data analysis and processing. Real-time marine environmental data and related reminders can be provided for oil and gas development platforms.
