Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0025] Embodiment one:

[0026] With reference to Figures 1-4 The present application provides an embodiment: an oil and gas pipeline detection device convenient to disassemble and assemble, comprising:

[0027] Two fixing assemblies 1, the fixing assembly 1 comprises a fixing shell 101, the lower part of the fixing shell 101 is symmetrically fixedly connected with a contact foot 102, the lower part of the contact foot 102 is fixedly connected with a permanent magnet 103, the cross-sectional shape of the permanent magnet 103 is rectangular, the number of the permanent magnet 103 is four in total, two as a group, and the magnetism of the two groups of permanent magnets 103 is opposite;

[0028] With reference to Figure 1 When installation is needed, the two fixing assemblies 1 can be fixed on the oil and gas pipeline by using the adsorption force of the two groups of permanent magnets 103, when disassembly is needed, the two fixing shells 101 can be separated from each other directly by driving the fixing seat 302, and the device can be quickly disassembled and assembled, so that the device is convenient to disassemble and assemble.

[0029] Two sealing assemblies 2, the sealing assembly 2 is arranged in the fixing shell 101 and is used for sealing the gap between the fixing shell 101 and the oil and gas pipeline;

[0030] The sealing assembly 2 comprises a front arc-shaped sealing piece 201 and a rear arc-shaped sealing piece 203, the longitudinal cross-sectional shape of the front arc-shaped sealing piece 201 and the rear arc-shaped sealing piece 203 is arc-shaped, and the front arc-shaped sealing piece 201 and the rear arc-shaped sealing piece 203 are fixedly connected with a connecting sealing piece 202;

[0031] With reference to Figure 1 , Figure 3 The front arc-shaped sealing piece 201, the rear arc-shaped sealing piece 203 and the connecting sealing piece 202 can all contact the outer surface of the oil and gas pipeline, so as to seal the gap between the fixing shell 101 and the oil and gas pipeline and avoid gas leakage.

[0032] Two warning components 3 are arranged on the fixed component 1, and the warning component 3 comprises a communication pipe 301 fixedly arranged on the fixed shell 101, an inner diameter pipe fixedly connected in the communication pipe 301, the inner diameter pipe being in communication with the fixed shell 101, a gas bag 303 fixedly connected on the inner diameter pipe, a fixed seat 302 fixedly connected on an end of the communication pipe 301 away from the fixed shell 101, and a fixed cover 304 fixedly connected on the fixed seat 302, the fixed cover 304 being made of transparent material, and the fixed cover 304 being provided with a contact switch 305 and an alarm device 306, the contact part of the contact switch 305 being located in the interior of the fixed cover 304.

[0033] Reference Figure 1 , Figure 2 , Figure 4 When the warning operation is performed, when gas leakage occurs in the oil and gas pipeline, the gas enters the fixed shell 101, and then enters the gas bag 303 from the inner diameter pipe. Due to the increase of the gas amount, the gas pressure gradually increases, thus the gas bag 303 is inflated, the gas bag 303 contacts the contact part of the contact switch 305, the contact switch 305 is connected, thus the alarm device 306 can work, thus the alarm operation is performed.

[0034] The alarm device 306 comprises an alarm lamp and a battery, and the battery is electrically connected with the alarm lamp and the contact switch 305.

This mode is suitable for the detection environment at night.

[0036] Working principle: two fixed shells 101 are arranged on the suspected leakage point of the oil and gas pipeline from the upper and lower sides, the two fixed components 1 are fixed on the oil and gas pipeline by the adsorption force of the two groups of permanent magnets 103, the front arc-shaped sealing piece 201, the rear arc-shaped sealing piece 203 and the connecting sealing piece 202 can contact the outer surface of the oil and gas pipeline, and the gap between the fixed shell 101 and the oil and gas pipeline is sealed, thus the gas leakage is avoided. When the gas leakage occurs in the oil and gas pipeline, the gas enters the fixed shell 101, and then enters the gas bag 303 from the inner diameter pipe. Due to the increase of the gas amount, the gas pressure gradually increases, thus the gas bag 303 is inflated, the gas bag 303 contacts the contact part of the contact switch 305, the contact switch 305 is connected, thus the alarm device 306 can work, the battery supplies power to the alarm lamp, the circuit of the alarm lamp is connected, thus the alarm lamp emits light, the alarm operation is performed, and the gas leakage can be directly judged. This mode is suitable for the detection environment at night.

[0037] Example two:

[0038] The difference from the first embodiment is that the alarm device 306 comprises an alarm horn, a battery, and the battery is electrically connected with the alarm horn and the contact switch 305.

[0039] During the alarm operation, the battery supplies power for the alarm horn, and the circuit of the alarm horn is in communication, thus the alarm horn can emit sound to alarm, and the gas leakage can be judged intuitively, and this kind of mode is suitable for use in a quiet environment.
