Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically to a pipeline leak detection device. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations.

[0003] Currently, during the pipeline production process, leak detection is required to ensure pipeline quality.

[0004] However, in implementing the relevant technologies, the following problems were found with existing pipeline inspection: it is difficult to perform large-scale automatic inspection of the produced pipelines; existing inspection devices require manual operation, which reduces the inspection efficiency and accuracy, and makes it difficult to guarantee the quality of the pipelines leaving the factory. Therefore, a pipeline leakage detection device is proposed. Utility Model Content

[0007] The top of the adjustment mechanism has two electric telescopic rods facing each other. The output ends of the two electric telescopic rods are fixedly connected to a support plate. A fixed rod is fixedly installed on one side of the support plate. An air bag is fixedly installed at one end of the fixed rod. An air supply pipe is fixedly installed through the axis of the fixed rod. A pressure sensor and a solenoid valve are fixedly installed on the outer side of the air supply pipe. An air pump is fixedly installed on the other side of the support plate. The output end of the air pump is fixedly connected to one end of the air supply pipe.

[0008] An air pump 2 is fixedly installed on the top of the support plate, and the output end of the air pump 2 is fixedly connected to the air inlet end of the airbag.

[0009] A buzzer is fixedly installed on the front side of the support plate, and the buzzer is electrically connected to the air pressure sensor through a controller.

[0010] Preferably, the adjustment mechanism includes a slide plate that is fixedly installed through the bottom wall of the U-shaped plate, a bidirectional screw is rotatably connected inside the slide plate, and two sliders are slidably connected inside the slide plate, with the two sliders threadedly connected to the bidirectional screw.

[0011] Preferably, a motor is fixedly installed on one side of the slide plate, the output end of the motor extends into the interior of the slide plate, and the output end is fixedly connected to one end of the bidirectional screw.

[0012] Preferably, the conveying mechanism includes an inclined plate that is relatively fixedly installed inside the U-shaped plate, and multiple conveying rollers that run through the inclined plate from left to right. One end of each of the multiple conveying rollers is fixedly installed with a double-groove synchronous pulley, and the double-groove synchronous pulleys are connected by a synchronous belt.

[0013] Preferably, a second motor is fixedly installed on one side of the U-shaped plate, and the output end of the second motor is fixedly connected to the shaft of the double-groove synchronous pulley.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] Motor 2 drives a double-groove synchronous pulley to rotate. Under the action of the synchronous belt, multiple conveyor rollers rotate on the inclined plate to transport the pipe into the U-shaped plate. The electric telescopic rod is activated, raising the airbag to both sides of the pipe. Motor 1 then drives a bidirectional screw to rotate inside the slide plate, connecting two sliders that slide relative to each other inside the slide plate. This is used to adjust and move the airbag to both ends of the pipe and insert it inside. Air pump 2 is activated, inflating the airbag to seal both ends of the pipe. After sealing, air pump 1 is activated, filling the pipe with air through the air supply pipe. The air pressure is detected by a pressure sensor. Once the pressure is reached, the solenoid valve closes. The pressure sensor also detects whether there is any leakage of air into the pipe. This system is effectively used for large-scale pipe testing in production workshops. Attached Figure Description
