[0002] Currently, industries such as petroleum, chemical, coal, power, metallurgy, and coking require large quantities of reaction gases, many of which are flammable, explosive, or toxic and harmful. Due to the high demand for gases in these industries, gas pipelines are typically used to transport them. Gas pipelines are laid over vast areas to achieve long-distance gas transport. These pipelines are usually made of metal or corrosion-resistant non-metallic materials. Although the pipelines are robust, leaks are inevitable during long-term use.

[0003] After pipeline installation, leak detection is required at pipe joints (pipe seams). For particularly vulnerable or special pipe seams, real-time monitoring is necessary to prevent leaks. However, current technology lacks effective products for detecting leaks at pipe seams. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0026] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0027] like Figures 1 to 2 As shown, a preferred embodiment of a leak detection transmitter is illustrated, comprising: a housing 1, an end cap 2, a bracket 3, a clamp 4, a connector 5, a diffused silicon core 6, a circuit board 7, a battery 8, and a flexible antenna 9.

[0028] The upper end of the housing 1 is open, and the end cap 2 is installed on the housing 1; the outer wall of the clamp 4 has a mounting hole, and the connector 5 is installed in the mounting hole; the upper end of the bracket 3 is installed on the lower end of the housing 1, and the lower end of the bracket 3 is installed on the outer wall of the clamp 4; the lower end of the housing 1 has a through hole, and the connector 5 extends into the interior of the housing 1 through the through hole; the diffused silicon core 6 is installed inside the connector 5, and the circuit board 7, battery 8 and flexible antenna 9 are all installed inside the housing 1, and the diffused silicon core 6, battery 8 and flexible antenna 9 are all electrically connected to the circuit board 7.

[0029] In actual use, under normal operating conditions (i.e., when there is no pipeline leakage), the pressure in the area between weld 14 and rubber 10 is 0. The transmitter collects data according to standard settings and uploads it to the system platform. When a pipeline leak occurs, the leaking medium enters the area between weld 14 and rubber 10, causing the pressure to rise. The leaking medium then enters the connector 5, and the diffused silicon core 6 immediately detects the pressure change and triggers an alarm. Simultaneously, the leak monitoring transmitter transmits the detected pressure data via flexible antenna 9, reporting it to the system platform in real time. The system platform has preset overload parameters; when the overload condition is reached, an alarm is issued. It can also determine whether weld 14 is leaking, thus achieving automated monitoring for real-time maintenance.

[0030] The housing 1 and end cap 2 of this device adopt a fully sealed structure, which enables the protection level to reach IP67. At the same time, the housing 1 is made of corrosion-resistant, sun-resistant and anti-aging materials, which can be suitable for various harsh environments and extend the service life of the product.

[0031] This device and the external detection system use low-power LoRa (Long Range Radio) signal transmission, which enables wireless data transmission and ensures that the product can be used in various complex, cramped, and power-difficult environments.

[0032] Based on the above, this utility model also has the following embodiments:

[0033] Furthermore, a leak detection transmitter further includes: a rubber 10; the rubber 10 is installed on the inner wall of the clamp 4, and the rubber 10 has a connection hole that communicates with the mounting hole. Further, the rubber 10 is used to improve the sealing between the clamp 4 and the pipeline, avoiding false detection. The rubber 10 is made of NBR (Nitrile Butadiene Rubber).

[0034] Furthermore, a leak detection transmitter further includes: a retaining ring 11; an annular groove is formed on the inner wall of the upper end of the connector 5, the annular groove is arranged circumferentially along the connector 5, the retaining ring 11 is installed in the annular groove, and the lower end of the retaining ring 11 abuts against the upper end of the diffused silicon core 6. Furthermore, through the cooperation of the retaining ring 11 and the annular groove, the diffused silicon core 6 is fixed inside the connector 5 to ensure the stability of the diffused silicon core 6.

[0035] Furthermore, a leak detection transmitter further includes: a sealant 12; the sealant 12 is installed on the bottom wall inside the housing 1, the circuit board 7 is installed on the upper surface of the sealant 12, and the upper end of the connector 5 penetrates through the upper surface of the sealant 12. Furthermore, the sealant 12 is used to ensure the sealing of the bottom of the housing 1, preventing external rainwater from entering and damaging the circuit.

Furthermore, the sealing ring 13 is used to ensure the sealing performance of the housing 1, preventing external rainwater from entering and damaging the circuit.

[0037] Furthermore, in a leak detection transmitter, the clamp 4 is a retractable clamp 4. Furthermore, the retractable clamp 4 facilitates easy and quick installation and disassembly of the entire unit.

[0038] Furthermore, in a leak detection transmitter, a flexible antenna 9 is fixedly installed on the inner wall of one side of the housing 1.

[0039] The installation steps of this device are as follows: First, weld the connector 5 to the mounting hole of the clamp 4 and perform a leak test. Then, fix the housing 1 to the bracket 3 with Phillips head screws and nuts. Electroweld the bracket 3 to the side wall of the clamp 4. The connector 5 should be able to pass through the through hole and extend into the interior of the housing 1. After completion, fill the bottom of the housing 1 with sealant 12 for about 2mm to seal the contact area between the connector 5 and the housing 1. Install the diffused silicon core 6 inside the connector 5 and use the retaining ring 11 for limiting and fixing, so that the diffused silicon core 6 does not become compressed. If it falls off, fix the circuit board 7 to the bottom of the housing 1 with a Phillips head screw. Insert the wire strip of the diffused silicon core 6 into the corresponding socket of the circuit board 7 to make the diffused silicon core 6 connected to the circuit board 7.
