Description

Technical Field

[0001] The utility model relates to the technical field of pipeline positioning, in particular to an acoustic gas PE pipeline positioning detection device. Background Art

[0002] According to the existing device, the patent publication number: CN220706766U discloses "an acoustic wave gas PE pipeline positioning device, which relates to the field of pipeline positioning. When the existing device moves inside the pipeline, when there is an object in the pipeline blocking it, the device is likely to tilt and lie horizontally in the pipeline, resulting in an inability to move. The following scheme is now proposed, which includes a mobile mounting column and a pipeline body. A detection mechanism is arranged on the outer side of the mobile mounting column, and the detection mechanism is used to detect and locate the inside of the pipeline body. A moving mechanism is arranged on the side wall of the mobile mounting column, and the moving mechanism drives the device to move. The moving mechanism includes an automatic roller and a stabilizing wheel group, and an elastic extension mechanism is arranged at the bottom of the automatic roller and the stabilizing wheel group. The utility model has a novel structure. Through the design of multiple wheels of the stabilizing wheel group and two automatic rollers on each side, it is supported by wheels when it is about to tilt, so as to avoid it lying horizontally in the pipeline."

[0003] However, when the pipeline bends and turns, when the detection device moves to the bend, due to the sudden increase in space, its rollers are easily separated from the pipe wall, resulting in obstruction of the movement of the device, thereby affecting the normal progress of the detection.

[0004] To this end, we proposed an acoustic gas PE pipeline positioning detection device. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1-2 In an embodiment of the utility model, an acoustic gas PE pipeline positioning detection device includes a fixing ring 1, a self-propelled mechanism and a shell 14.

[0023] There are three fixed rings 1 in total, and the three fixed rings 1 are evenly and circumferentially distributed and staggered with each other. The outer surface of the fixed ring 1 is provided with a self-propelled mechanism, and the outer surfaces of the intersections of the two fixed rings 1 are provided with a self-propelled mechanism, and the self-propelled mechanism includes a sleeve 8, a slide bar 12, a spring 13, a U-shaped plate 11, a walking wheel 2 and a walking motor 10. The sleeve 8 is fixed to the outer surface of the fixed ring 1, and the inner wall of the sleeve 8 is slidably connected with the slide bar 12, the bottom end of the slide bar 12 is connected to the bottom wall of the sleeve 8 through the spring 13, and the top of the slide bar 12 is fixedly connected with the U-shaped plate 11, a walking wheel 2 is rotatably connected between the inner walls on both sides of the U-shaped plate 11, and a walking motor 10 is fixedly connected to one side of the U-shaped plate 11, the output end of the walking motor 10 passes through the inner wall of the U-shaped plate 11 and is fixedly connected to the rotating shaft of the walking wheel 2 through a coupling, the outer surface of the shell 14 is fixedly connected to the inner wall of the fixing ring 1 through a plurality of support rods 4, and scrapers 7 are fixedly connected to both sides of the lower inner wall of the U-shaped plate 11, and a telescopic rod 9 is fixedly connected between the lower inner wall of the sliding rod 12 and the lower inner wall of the sleeve 8, and a spring 13 is strung on the outside of the telescopic rod 9.

[0024] It should be noted that, by means of three evenly distributed fixing rings 1 that are staggered and fixed to each other, the walking wheel 2 can fit the pipe wall more closely, thus ensuring the stability of the device on the gas PE pipeline and reducing the shaking and instability of the device when moving in the pipeline. When moving, the walking motor 10 works, thereby driving the walking wheel 2 to rotate, thereby achieving the walking detection effect of the device, and the mutual cooperation of the sleeve 8, the slide bar 12, the spring 13 and the telescopic rod 9 enables the walking wheel to maintain stable movement in an uneven pipeline, with stronger adaptability. When there is sticky dirt on the surface of the walking wheel 2, due to the presence of the scraper 7, the dirt on the surface of the walking wheel 2 can be scraped off, reducing the impact on the movement of the device, which is beneficial to detection. When moving to the bend, the space suddenly increases. Since the device is spherical as a whole, the walking wheel 2 can also fit well with the pipe wall, which is beneficial to walking detection.

[0025] The outer surface of the shell 14 is fixedly connected with a GPS locator 6 , an infrasonic wave sensor 3 , a gas concentration sensor 5 and an alarm 15 , and the shell 14 is located at the center of the fixing ring 1 , and a battery is fixedly installed inside the shell 14 .

[0026] It should be noted that the shell 14 is installed at the center of the device, so that the distance between the sensor and the pipe wall can be kept stable, reducing the error caused during the movement of the device and improving the detection effect. Due to the presence of the battery, the continuous power supply of the device inside the pipeline is guaranteed, so that the device has a strong independent working ability. When a gas pipeline leaks, the gas concentration here is low. At the same time, the gas will generate infrasound when it leaks. The detection effect is achieved through the gas concentration sensor 5 and the infrasound sensor 3, and the leakage site can be located through the GPS locator 6 and the alarm 15, which is convenient for timely processing.
