DETAILED DESCRIPTION

[0026] Figure 1 FIG. 1 is a schematic diagram of the structure of a combustible gas monitoring device 1 on a field mobile platform shown in an embodiment. Figure 1 As shown, the combustible gas monitoring device 1 on the field mobile platform includes a tracked vehicle 10, a lifting rod 20, a pan / tilt head 30 and a monitoring component 40. The monitoring component 40 includes a combustible gas monitor 41. The combustible gas monitor 41 is used to detect the concentration of combustible gas in the environment.

[0027] The lifting rod 20 is provided on the crawler vehicle 10, and the crawler vehicle 10 can travel in the field. The lifting rod 20 can move up and down relative to the crawler vehicle 10, and the pan head 30 is provided on the top of the lifting rod 20, and the pan head 30 can rotate relative to the lifting rod 20. By providing the crawler vehicle 10, the combustible gas monitoring device 1 can travel on uneven ground in the field and can withstand a large load. By providing the lifting rod 20, it is convenient to raise the pan head 30 and the combustible gas monitor 41 provided on the pan head 30 to a higher position, and the pan head 30 can rotate relative to the lifting rod 20, which can improve the monitoring range and monitoring accuracy of the combustible gas monitor 41.

[0028] When in use, the combustible gas monitoring device 1 can be placed in the field where it is necessary to monitor whether the combustible gas leaks. For example, when construction is carried out above a buried pipeline, the combustible gas monitoring device 1 can be placed near the construction site to promptly detect whether the combustible gas is leaking, thereby preventing the oil and gas pipeline from being damaged during the construction process and failing to take effective measures in time, resulting in a combustible gas leak.

[0029] The combustible gas monitoring device 1 also includes a power supply system 50, which is used to supply power to the combustible gas monitoring device 1 to prevent the combustible gas monitoring device 1 from being in an environment without city power supply for a long time, and insufficient power affecting the operation of the combustible gas monitoring device 1.

[0030] Please also refer to Figure 1 and Figure 2 The power supply system 50 includes a battery 51 and a power generation system 60. The battery 51 is electrically connected to the monitoring component 40 for supplying power to the monitoring component 40. The power generation system 60 includes a wind power generation device 61 and a solar power generation device 62. The wind power generation device 61 and the solar power generation device 62 are electrically connected to the battery 51 for charging the battery 51.

[0031] The power supply system 50 of the combustible gas monitoring device 1 on the field mobile platform provided by the present application includes a battery 51 and a power generation system 60. The battery 51 is electrically connected to the monitoring component 40 of the combustible gas monitoring device 1 on the field mobile platform, and is used to supply power to the monitoring component 40, so that the monitoring component 40 can monitor the combustible gas in the environment. By making the power generation system 60 include a wind power generation device 61 and a solar power generation device 62, the wind power generation device 61 and the solar power generation device 62 are electrically connected to the battery 51, and are used to charge the battery 51, the wind energy and solar energy in the field environment can be fully utilized to charge the battery 51, and the power of the battery 51 can be replenished in time, thereby increasing the operating time of the monitoring component 40, avoiding the monitoring component 40 from being unable to work due to lack of power supply, and making the combustible gas monitoring device 1 more adaptable to the field environment.

[0032] exist Figure 2In the illustrated embodiment, the power generation system 60 includes a wind-solar hybrid controller 63 , which is electrically connected to the wind power generation device 61 and the solar power generation device 62 for controlling the wind power generation device 61 and the solar power generation device 62 .

[0033] The wind-solar hybrid controller 63 is an intelligent controller specially customized for wind and solar power generation. It integrates wind control and solar control, fully utilizes wind and light energy resources for power generation, and reduces power supply shortages or imbalances caused by the use of a single energy source. The wind-solar hybrid controller 63 can be set to improve the quantity and quality of power generation by the wind power generation device 61 and the solar power generation device 62.

[0034] The power generation system 60 includes a first switch 64 and a second switch 65. The first switch 64 is connected between the wind power generation device 61 and the battery 51 to control the on and off of the wind power generation device 61 and the battery 51. The second switch 65 is connected between the solar power generation device 62 and the battery 51 to control the on and off of the solar power generation device 62 and the battery 51.

[0035] By setting the first switch 64 and the second switch 65, the first switch 64 and the second switch 65 can be turned on or off. When the combustible gas monitoring device 1 on the field mobile platform is in the field and it is necessary to monitor the combustible gas in the field environment, the first switch 64 and the second switch 65 can be turned on, and the wind power generation device 61 and the solar power generation device 62 use the wind energy and solar energy in the field environment to charge the battery 51. When the combustible gas monitoring device 1 on the field mobile platform is placed indoors and is not in a working state, the first switch 64 and the second switch 65 can be turned off, and the wind power generation device 61 and the solar power generation device cannot charge the battery 51. The on and off of the first switch 64 and the second switch 65 can also be adjusted according to the field environment so that the battery is charged only by the wind power generation device 61 or the solar power generation device 62.

[0036] In this embodiment, the monitoring assembly 40, the battery 51 and the power generation system 60 are all arranged on the crawler 10, and the crawler 10 provides a space for the monitoring assembly 40, the battery 51 and the power generation system 60, and the crawler 10 can travel on uneven ground in the field, solving the problem that ordinary vehicles cannot enter some construction sites. The battery 51 is electrically connected to the crawler 10 to supply power to the crawler 10, so that the crawler 10 can travel to a position suitable for setting the monitoring assembly 40. Generally, the crawler 10 is parked at the downwind position of the pipeline.

[0037] Figure 2In the illustrated embodiment, the battery 51 includes a first port 511 and a second port 512. The first port 511 is electrically connected to the tracked vehicle 10 for supplying power to the tracked vehicle 10. The second port 512 is electrically connected to the monitoring component 40 for supplying power to the monitoring component 40. Since the tracked vehicle 10 consumes power faster while the monitoring component 40 consumes power slower, in this embodiment, the output voltage of the first port 511 electrically connected to the tracked vehicle 10 is 48V, and the output voltage of the second port 512 electrically connected to the monitoring component 40 is 24V. The battery 51 includes a step-down circuit 52. The input end of the step-down circuit 52 is connected to the battery 51. The step-down circuit 52 is used to reduce the voltage output by the battery 51. The output end of the step-down circuit 52 is connected to the monitoring component 40. The step-down circuit 52 is connected to the monitoring component 40 through the second port 512. This allows the same battery 51 to supply power to both the tracked vehicle 10 and the monitoring component 40. It can be understood that the number of step-down circuits 52 in the present patent application can be multiple, and the output voltage of the battery 51 can be reduced to multiple different voltage values ​​to meet the voltage requirements of different monitoring products in the monitoring component 40. For example, the monitoring component also includes a camera and anemometer, etc. The working voltage of the camera and the working voltage of the anemometer may be different from the working voltage of the combustible gas monitor, so multiple step-down circuits are required.

[0038] exist Figure 2 In the illustrated embodiment, the power supply system 50 further includes a controller 70, and the battery 51 includes a power collector 54, which can collect power information of the battery 51. The controller 70 is electrically connected to the power collector 54, and is used to receive the power information of the battery 51 collected by the power collector 54. In some other embodiments, the controller 70 can also synchronize the power information of the battery 51 to the terminal device in a timely manner, so that the staff can immediately understand the power status of the battery 51.

[0039] The power supply system 50 further includes a power feed alarm 71, and the controller 70 is electrically connected to the power feed alarm 71, and is used to control the power feed alarm 71 to sound an alarm when the power level of the battery 51 is lower than the power threshold, so as to remind the staff to replenish the power in time, so as to avoid the monitoring component 40 being unable to work, and then being unable to monitor the combustible gas content in the environment, and failing to discover risks in time.

[0040] In some embodiments, the power generation system 60 further includes a fuel power generation device 66, which is electrically connected to the battery 51 and is used to generate electricity using fuel to charge the battery 51. When the combustible gas monitoring device 1 is in the field and has a long working time, and the solar energy or wind energy is insufficient, the amount of electricity generated is insufficient to offset the energy consumption of the monitoring component 40, and the electric energy stored in the battery 51 is almost gone, the battery 51 can be charged by the fuel power generation device 66. The fuel power generation device 66 is arranged in the crawler 10 as an essential spare part of the combustible gas monitoring device 1, and plays a role in extreme weather.

[0041] The power supply system 50 further includes a mains charging device 67, which is electrically connected to the battery 51 and is used to connect to a mains power source to charge the battery 51. The mains charging device 67 includes a mains charging interface and a charging wire. Before the combustible gas monitoring device 1 is set out to the field, the battery 51 can be quickly fully charged through the mains charging device 67.

[0042] The power generation system 60 further includes a third switch 68 and a fourth switch 69. The third switch 68 is connected between the fuel power generation device 66 and the battery 51, and the fourth switch 69 is connected between the mains charging device 67 and the battery 51. The third switch 68 is used to control the on-off between the fuel power generation device 66 and the battery 51, and the fourth switch 69 is used to control the on-off between the mains charging device 67 and the battery 51.

[0043] Because both the fuel-fired power generation device 66 and the mains charging device 67 are high-power charging, it is necessary to avoid charging the battery 51 in two ways at the same time. In some preferred embodiments, the third switch 68 and the fourth switch 69 are linked switches. When one of the third switch 68 and the fourth switch 69 is turned on, the other is turned off. The third switch 68 and the fourth switch 69 will not be turned on at the same time, thereby avoiding charging the battery 51 through the fuel-fired power generation device 66 and the mains charging device 67 at the same time.
