Description

Technical Field

[0001] The invention relates to the technical field of gas pipelines, and in particular to a gas pipeline sealing detection device. Background Art

[0002] After the gas pipeline is laid, its construction quality needs to be inspected. One of the important inspection indicators is the airtightness of the pipeline. If the gas pipeline is not airtight and is not inspected in time, it will not only cause waste of gas, but also as the gas accumulates in the outside world, it will immediately burn when encountering an open flame, thus affecting the pipeline and causing a large-scale explosion, posing a great safety hazard.

[0003] A common detection method is to inject gas into the gas pipeline to see if the gas pressure can remain stable. However, traditional devices can only be connected to pipes with threads or other installation ports. When encountering smooth pipes without installation ports, the device cannot be stably connected to the pipe, resulting in inaccurate detection results. Therefore, in view of the above situation, it is urgent to develop a gas pipeline sealing detection device to overcome the shortcomings in current practical applications. Summary of the invention

[0004] The purpose of the present invention is to provide a gas pipeline sealing detection device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A gas pipeline sealing detection device, comprising:

[0007] Testing box;

[0008] A measuring mechanism, which is connected to the detection box and is used to convey air and measure the air pressure;

[0009] A fixing mechanism, the fixing mechanism is arranged on the wall of the detection box;

[0010] A driving mechanism, the driving mechanism is arranged between the detection box and the fixing mechanism, and is used to drive the fixing mechanism to clamp the gas pipeline and complete the adsorption and fixing of the gas pipeline;

[0011] Wherein, the driving mechanism comprises:

[0012] A control component, wherein the control component is connected to the detection box;

[0013] A transmission assembly, which is disposed between the control assembly and the fixing mechanism and is used to cooperate with the control assembly to drive the fixing mechanism to move and clamp the gas pipeline;

[0014] A connecting component is arranged between the control component and the fixing mechanism, and is used to cooperate with the control component to drive the fixing mechanism to complete the adsorption and fixing of the gas pipeline.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the device is running, after the gas pipeline enters the inner side of the detection box, the control component drives the fixing mechanism to move through the transmission component to clamp the gas pipeline. When the fixing mechanism contacts the pipe wall of the gas pipeline, the control component will continue to drive the fixing mechanism through the transmission component on the one hand, so that the contact between the fixing mechanism and the gas pipeline is more sufficient. On the other hand, it can drive the fixing mechanism through the connecting component so that the fixing mechanism is adsorbed and connected to the gas pipeline, thereby completing the fixation of the gas pipeline. The measuring mechanism cooperates with the fixed gas pipeline to complete the detection of the sealing of the gas pipeline. Compared with the detection device in the prior art, the present application can only be connected to a pipeline with a thread or other installation port. When encountering a smooth pipeline without an installation port, the device cannot be stably connected to the pipeline, resulting in inaccurate detection results. By setting a fixing mechanism and a driving mechanism, the control component drives the fixing mechanism through the transmission component and the connecting component, so that the fixing mechanism can cooperate with the detection box to complete the clamping and adsorption fixation of the pipeline, thereby ensuring the stability of the gas pipeline during the detection process, and then enabling the measuring mechanism to accurately detect the sealing of the gas pipeline.
