Description

Technical Field

[0001] This utility model relates to the technical field of gas monitoring equipment inside offshore steel pipe pile foundations, and in particular to an intelligent monitoring and emission device for harmful gases inside offshore steel pipe pile foundations. Background Technology

[0002] Offshore steel pipe pile foundations serve as the foundation for offshore structures (such as jacket platforms, wind turbine towers, and cross-sea bridges), providing essential support to ensure the stability of these structures in harsh marine environments. The hollow internal structure of offshore steel pipe pile foundations helps reduce weight and improve installation efficiency. During installation, the lower part of the foundation is inserted to a certain depth below the seabed for fixation, while the upper part connects to the offshore structure.

[0003] Changes in seabed geology and wave impact can alter the stress distribution within the pipe piles, potentially leading to structural fatigue or damage over time. Therefore, regular inspections by maintenance personnel are necessary. The interior of the offshore steel pipe pile foundation may contain harmful gases such as hydrogen sulfide, nitrogen oxides, formaldehyde, and carbon dioxide, which can accumulate due to microbial decomposition in seawater and chemical reactions between the seawater and the foundation. Maintenance personnel entering the pipes may inhale these harmful gases, causing dizziness, nausea, and in severe cases, suffocation, jeopardizing their health. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes an intelligent monitoring and emission device for harmful gases inside offshore steel pipe pile foundations, which can monitor the presence of harmful gases inside offshore steel pipe pile foundations in real time and automatically emit them, effectively preventing maintenance personnel from entering the offshore steel pipe pile foundations and inhaling harmful gases.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An intelligent monitoring and emission device for harmful gases inside a marine steel pipe pile foundation is installed on the marine steel pipe pile foundation. The top of the marine steel pipe pile foundation is also provided with a personnel access passage, and a cover is installed on the personnel access passage.

[0007] include:

[0008] An air intake pipe is installed inside the offshore steel pipe pile foundation. The air intake pipe is wound with an electric heating wire for heating the gas inside the air intake pipe. The air outlet at the lower end of the air intake pipe is located at the bottom of the offshore steel pipe pile foundation. A temperature sensor is installed at the air outlet at the lower end of the air intake pipe. The air intake at the upper end of the air intake pipe extends out of the top of the offshore steel pipe pile foundation.

[0009] An array of multiple gas detection sensors installed vertically and at intervals inside the offshore steel pipe pile foundation;

[0010] An air pump device is installed outside the offshore steel pipe pile foundation, and the air pump device is connected to the air inlet at the upper end of the air inlet pipe.

[0011] In addition, the power supply, controller, and touch screen are installed on the cover;

[0012] The power supply, heating wire, temperature sensor, air pump, touch screen, and each gas detection sensor array are electrically connected to the controller.

[0013] Furthermore, the gas detection sensor array includes a hydrogen sulfide gas sensor, a nitrogen oxide gas sensor, a formaldehyde gas sensor, and a carbon dioxide gas sensor.

[0014] Furthermore, it also includes an audible and visual alarm, which is installed on the cover; the audible and visual alarm is electrically connected to the controller.

[0015] Furthermore, it also includes a human body sensor, which is disposed on the cover; the human body sensor is electrically connected to the controller.

[0016] Furthermore, it also includes a wireless communication module; the wireless communication module is electrically connected to the controller.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0018] This intelligent monitoring and emission device for harmful gases inside offshore steel pipe pile foundations can monitor the distribution and concentration of harmful gases at various heights within the foundation. Before personnel enter the foundation, the cover is opened, and gas is pumped in via an air pump. The gas is heated by an electric heating wire, causing it to rise from the bottom of the foundation and create an airflow disturbance similar to a "chimney effect." This turbulence expels harmful gases from the foundation through the personnel access points until no harmful gases are detected at any height within the foundation. Only then can personnel enter. This effectively prevents maintenance personnel from inhaling harmful gases inside offshore steel pipe pile foundations. Attached Figure Description

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to Figures 1-3 This embodiment provides an intelligent monitoring and emission device for harmful gases inside a marine steel pipe pile foundation, installed on a marine steel pipe pile foundation 100. The top of the marine steel pipe pile foundation 100 also has a personnel access passage (not marked in the figure), and a cover 200 is installed on the personnel access passage. Both the marine steel pipe pile foundation 100 and the cover 200 of the personnel access passage installed on the marine steel pipe pile foundation 100 are existing equipment structures. This utility model does not involve improvements to the above structures and will not be described in detail here.

[0024] The intelligent monitoring and emission device for harmful gases inside the offshore steel pipe pile foundation includes:

[0025] An air inlet pipe 1 is installed inside the offshore steel pipe pile foundation 100, and an electric heating wire 2 for heating the gas inside the air inlet pipe 1 is wound around the air inlet pipe 1. The air outlet at the lower end of the air inlet pipe 1 is located at the bottom of the interior of the offshore steel pipe pile foundation 100.

[0026] A temperature sensor 3 is installed at the outlet (not marked in the figure) at the lower end of the air inlet pipe 1 to detect the temperature of the gas discharged into the marine steel pipe pile foundation 100 by the air inlet pipe 1.

[0027] An air inlet (not marked in the figure) located at the upper end of the air inlet pipe 1 extends through the top of the offshore steel pipe pile foundation 100 (not shown in the figure).

[0028] Multiple gas detection sensor arrays 4 are vertically and spaced apart inside the offshore steel pipe pile foundation 100. Each of the gas detection sensor arrays 4 includes a hydrogen sulfide gas sensor, a nitrogen oxide gas sensor, a formaldehyde gas sensor, and a carbon dioxide gas sensor, which are used to detect the gas concentrations of hydrogen sulfide, nitrogen oxides, formaldehyde, and carbon dioxide, respectively.

[0029] like Figure 1 and Figure 2 As shown, an air pump device 5 is installed outside the offshore steel pipe pile foundation 100. The air pump device 5 is connected to the air inlet at the upper end of the air inlet pipe 1, and external gas is pumped into the air inlet pipe 1 through the air pump device 5.

[0030] The cover 200 also includes a controller 6, a power supply 7, an audible and visual alarm 8, a human body sensor 9, a touch screen display 10, and a wireless communication module 11. These components can also be installed at other locations on top of the offshore steel pipe pile foundation 100. However, it should be noted that the human body sensor 9 should be installed in a way that allows it to detect a person approaching the cover 200.

[0031] All of the above-mentioned electronic devices are existing devices, and those skilled in the art should have the conventional ability to select such electronic devices. Preferably, the controller 6 is a Siemens S7-200 programmable controller; the wireless communication module 11 is a 3G communication module.

[0032] The power supply device 7 is electrically connected to the controller 6, providing power to the controller 6. The heating wire 2, temperature sensor 3, air pump device 5, audible and visual alarm 8, human body sensor 9, touch screen 10, wireless communication module 11, and each gas detection sensor array 4 are electrically connected to the controller 6. The technical means of electrically connecting the above-mentioned electronic devices are conventional techniques in the art and will not be described in detail here. Those skilled in the art can reproduce this intelligent monitoring and emission device for harmful gases inside the offshore steel pipe pile foundation and achieve the same technical effects based on the functions of each electronic device described in this specification and the electrical connection methods shown in the accompanying drawings.

[0033] When using:

[0034] Each gas detection sensor array 4 monitors the concentrations of hydrogen sulfide, nitrogen oxides, formaldehyde, and carbon dioxide at various height positions of the offshore steel pipe pile foundation 100 and displays them on the touch screen 10.

[0035] When the human body sensor 9 detects that someone is approaching the cover 200, if the concentration of hydrogen sulfide gas, nitrogen oxide gas, formaldehyde gas, or carbon dioxide gas exceeds the standard (the safe concentration of hydrogen sulfide gas, nitrogen oxide gas, formaldehyde gas, and carbon dioxide gas can be set), the sound and light alarm 8 will be controlled to issue a warning, reminding the staff not to enter the interior of the offshore steel pipe pile foundation 100.

[0036] Users can operate the touch screen 10 to control the air pump 5 to pump gas into the air inlet pipe 1 and control the heating wire 2 to heat the gas in the air inlet pipe 1, such as heating the gas in the air inlet pipe 1 to 70℃-80℃. The temperature sensor 3 is used to detect the gas temperature and display it on the touch screen 10. The heated gas temperature is higher than the original gas temperature inside the steel pipe pile foundation 100. The high-temperature gas will rise from the bottom of the steel pipe pile foundation 100, forming an airflow disturbance similar to the "chimney effect", which will discharge the harmful gases inside the steel pipe pile foundation 100 through the personnel access passage until the concentrations of hydrogen sulfide, nitrogen oxides, formaldehyde, and carbon dioxide at various height positions inside the steel pipe pile foundation 100 are within the safe range. Then the heating wire 2 stops heating, but it is necessary to continue pumping unheated air into the steel pipe pile foundation 100 for a period of time (such as 15 minutes) to quickly cool the air inside the steel pipe pile foundation 100. After that, the audible and visual alarm 8 stops emitting alarms. Of course, after the air pump device 5 stops, the staff should also observe the touch screen 10 to check the internal temperature of the steel pipe pile foundation 100 (detected by the temperature sensor). If the temperature is high (e.g., exceeding 40°C), they can wait for the internal temperature of the steel pipe pile foundation 100 to continue to cool naturally, or control the air pump device 5 through the touch screen 10 to continue pumping unheated air into the steel pipe pile foundation 100 so that the internal temperature of the steel pipe pile foundation 100 drops. Only then can the staff safely enter the steel pipe pile foundation 100 to carry out maintenance work.

[0037] This intelligent monitoring and emission device for harmful gases inside offshore steel pipe pile foundations can monitor the presence of harmful gases inside the foundations in real time and automatically emit them, effectively preventing maintenance personnel from inhaling harmful gases when entering the foundations. It is practical.

[0038] The aforementioned wireless communication module 11 can also be replaced by a 4G communication module, a 5G communication module, a 2.4G communication module, an NB-IoT communication module, etc.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
