However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an explosion-proof inspection device for petroleum safety, comprising a lower shell 1 and an upper shell 11, both sides of the lower shell 1 and the upper shell 11 are fixedly connected with a group of connecting plates 12, and the outer surfaces of the two groups of connecting plates 12 are provided with connecting mechanisms 4, and the front and rear sides of the lower shell 1 and the upper shell 11 are provided with sealing mechanisms 2, and the connecting mechanism 4 comprises a U-shaped card 401, and the top center of the U-shaped card 401 is threadedly connected with an adjusting bolt 402, and the bottom end of the adjusting bolt 402 is rotatably connected with a pressing plate 403, and the top of the pressing plate 403 is in conflict with the outer surface of the connecting plate 12, and the inner bottom of the U-shaped card 401 is in conflict with the outer surface of the connecting plate 12, and the number of the sealing mechanisms 2 is set to four, which are respectively provided at the front and rear sides of the upper shell 11 and the lower shell 1, and the four sealing mechanisms 2 all include sealing Plate 201, wherein two sealing plates 201 are fixedly connected between the inner surface walls of the lower shell 1 near the front and rear side edges, and the other two sealing plates 201 are fixedly connected between the inner surface walls of the upper shell 11 near the front and rear side edges, the outer surface of the sealing plate 201 is fixedly connected with an arc clamping plate 202, and the adjacent arc clamping plates 202 are symmetrically arranged, a gas sensor 3 is installed on the top of the upper shell 11, a temperature sensor 31 is installed on the top of the upper shell 11 at the rear side of the gas sensor 3, a pressure sensor 32 is installed on the top of the upper shell 11 at the rear side of the temperature sensor 31, and an audible and visual alarm 33 is installed on the top of the upper shell 11 near one side edge, and the detection ends of the gas sensor 3, the temperature sensor 31 and the pressure sensor 32 all pass through the top of the upper shell 11 and extend to the bottom.

[0023] The effect achieved by the entire embodiment 1 is that when the device is in use, the lower shell 1 and the upper shell 11 are clamped on the oil pipe connection and aligned. At this time, the four arc-shaped clamping plates 202 cooperate with the sealing plate 201 to seal the exposed positions of the front and rear sides of the lower shell 1 and the upper shell 11, so that a closed space is formed between the lower shell 1 and the upper shell 11 and the surface of the oil pipe, and then the two U-shaped clamps 401 are sleeved on the outside of the connecting plate 12 that is tightly attached to the two sides of the lower shell 1 and the upper shell 11. At this time, the adjusting bolt 402 is rotated to drive the pressure plate 403 inside the U-shaped clamp 401 to move downward. After the pressure plate 403 moves downward, it has the effect of squeezing and fixing the adjacent connecting plates 12, thereby achieving the effect of installing the device to the oil pipe connection. The steps are reversed when removing, and the disassembly and assembly are relatively convenient. After the installation of the device is completed, the gas sensor 3, the temperature sensor 31 and the pressure sensor 32 The petroleum content, temperature and air pressure stability in the gas inside the device will be continuously monitored. When any of the petroleum content, gas temperature and air pressure values ​​at the oil pipe connection exceeds the threshold, an electrical signal will be sent to activate the sound and light alarm 33 to sound an alarm, thereby providing staff with processing time to avoid safety hazards. The gas sensor 3, temperature sensor 31, pressure sensor 32 and sound and light alarm 33 in the device are all mature products on the market. Their control systems and power supplies are provided through external lines and terminal connections. They are existing mature technologies and will not be elaborated on here. The device uses a pressure plate 403 in conjunction with a U-shaped card 401 to squeeze and fix the adjacent connecting plates 12, which not only facilitates disassembly and assembly, but also allows different positions of the connecting plates 12 to be effectively subjected to the squeezing force, and the force is relatively uniform.

[0025] The effect achieved by the entire embodiment 2 is that after the installation of the device is completed, the first sealing gaskets 13 on the surfaces of adjacent connecting plates 12 will be squeezed against each other, and the second sealing gaskets 203 on the adjacent surfaces of adjacent arc-shaped clamping plates 202 will fit tightly against the surface of the oil pipe, thereby improving the airtightness of the device and ensuring that the gas conditions at the oil pipe connection can be accurately detected with high reliability. When the pressure plate 403 is driven up and down by the adjusting bolt 402, the limit rod 404 serves to limit the pressure plate 403.

[0026] Working principle: When the device is in use, the lower shell 1 and the upper shell 11 are clamped on the oil pipe connection and aligned. At this time, the four arc-shaped clamping plates 202 cooperate with the sealing plate 201 to seal the exposed positions of the front and rear sides of the lower shell 1 and the upper shell 11, so that a closed space is formed between the lower shell 1 and the upper shell 11 and the surface of the oil pipe. Then, the two U-shaped clamps 401 are sleeved on the outside of the connecting plate 12 that is tightly attached to the lower shell 1 and the upper shell 11. At this time, the adjusting bolt 402 is rotated to drive the pressure plate 403 inside the U-shaped clamp 401 to move downward. After the pressure plate 403 moves downward, it has the effect of squeezing and fixing the adjacent connecting plates 12, thereby achieving the effect of installing the device to the oil pipe connection. When removing, the steps are reversed, and the disassembly and assembly are more convenient. After the device is installed, After completion, the gas sensor 3, the temperature sensor 31 and the pressure sensor 32 will continue to monitor the petroleum content, temperature and air pressure stability in the gas inside the device. When any of the petroleum content, gas temperature and air pressure values ​​at the oil pipe connection exceeds the threshold, an electrical signal will be sent to activate the sound and light alarm 33 to sound an alarm, thereby providing the staff with processing time to avoid safety hazards. In addition, after the installation of the device is completed, the first sealing gaskets 13 on the surfaces of adjacent connecting plates 12 will squeeze each other, and the second sealing gaskets 203 on the adjacent surfaces of adjacent arc-shaped clamps 202 will fit tightly against the surface of the oil pipe, thereby improving the airtightness of the device and ensuring that the gas conditions at the oil pipe connection can be accurately detected with high reliability.
