[0137] In some of these embodiments, the second valve body 530 includes, but is not limited to, a three-way valve.

[0138] like Figure 6 As shown, the control unit 600 includes a communication component 610 and a control component 620. The communication component 610 is disposed on the body component 100 and connected to an external remote control device for receiving and transmitting signals. The control component 620 is disposed on the body component 100 and connected to the communication component 610, the moving component 200, the adjusting component, the first blocking component 400, and the second blocking component 500, respectively, for controlling the moving component 200, the adjusting component, the first blocking component 400, and the second blocking component 500.

[0139] Specifically, the communication component 610 is installed inside the first housing component 110 by means of welding, riveting or bolting, and is connected to external remote control devices by means of wireless connection.

[0140] In some embodiments, the communication device 610 includes, but is not limited to, a Bluetooth sensor, a WiFi sensor, and a ZigBee sensor.

[0141] Specifically, the control component 620 is installed inside the first housing component 110 by means of welding, riveting or bolting, and is connected to the communication component 610, the drive component 230, the adjustment component 310, the first inflation component 420, the first valve body component 430, the second inflation component 520 and the second valve body component 530 by means of wired connection, etc., and is used to control the start and stop of the drive component 230, the adjustment component 310, the first inflation component 420, the first valve body component 430, the second inflation component 520 and the second valve body component 530.

[0142] In some of these embodiments, the controller 620 includes, but is not limited to, an MCU, a Raspberry Pi, or a microcontroller.

[0143] The usage method of this embodiment is as follows:

[0144] In actual operation, the blocking device is placed inside the gas pipeline, and the regulating component 310 is activated by the control component 620. The regulating component 310 can make the moving component 270 abut against the inner wall of the gas pipeline.

[0145] The control unit 620 starts the drive unit 230, which can drive the moving part 270 to rotate, thereby allowing the blocking device to move to the corresponding leak point in the gas pipeline.

[0146] The control unit 620 activates the first inflation unit 420, the first valve body 430, the second inflation unit 520, and the second valve body 530, causing the first blocking unit 410 and the second blocking unit 510 to expand, thereby blocking both ends of the leak point and facilitating subsequent maintenance by maintenance personnel.

[0147] The advantages of this embodiment are that by setting a moving part, the blocking device can move freely inside the gas pipeline, improving the flexibility of the blocking device; by setting an adjusting part, the moving part can abut against the inner wall of the gas pipeline, thereby making the blocking device adaptable to gas pipelines of different sizes, improving the applicability of the blocking device; by setting a first blocking part and a second blocking part at both ends of the body component, and achieving the blocking of the gas pipeline by inflating, and by releasing the gas to retract after maintenance, the first and second blocking parts can be prevented from rubbing against the inner wall of the gas pipeline during the movement of the blocking device, thus improving the safety of the blocking device.

[0148] Example 2

[0149] This embodiment is a modified embodiment of embodiment 1.

[0150] like Figure 7 and Figure 8 As shown, the blocking device also includes a first telescopic component 700 and a second telescopic component 800. The first telescopic component 700 is disposed between the first end of the body component 100 and the first blocking component 400, and is connected to the control component 600, for adjusting the distance between the first blocking component 400 and the second blocking component 500; the second telescopic component 800 is disposed between the second end of the body component 100 and the second blocking component 500, and is connected to the control component 600, for adjusting the distance between the second blocking component 500 and the first blocking component 400.

[0151] Specifically, the first telescopic component 700 includes a first telescopic member. The first telescopic member is disposed at the first end of the body component 100 and connected to the control component 600, and the output shaft of the first telescopic member is connected to the first blocking component 400 for adjusting the distance between the first blocking component 400 and the second blocking component 500.

[0152] More specifically, the first telescopic member is installed inside the second housing 120 by means of welding, riveting or bolting, and the output shaft of the first telescopic member is connected to the first blocking member 410, so that the first telescopic member can extend the first blocking member 410 outward.

[0153] In some of these embodiments, the first telescopic member includes, but is not limited to, a telescopic motor.

[0154] Specifically, the second telescopic component 800 includes a second telescopic member. The second telescopic member is disposed at the second end of the body component 100 and connected to the control component 600. The output shaft of the second telescopic member is connected to the second blocking component 500 for adjusting the distance between the second blocking component 500 and the first blocking component 400.

[0155] More specifically, the second telescopic member is installed inside the second housing 120 by means of welding, riveting or bolting, and the output shaft of the second telescopic member is connected to the second blocking member 510, so that the second telescopic member can extend the second blocking member 510 outward.

[0156] In some embodiments, the second telescopic member includes, but is not limited to, a telescopic motor.

[0157] It should be noted that in the event of two adjacent leaks in the gas pipeline, the first and second expansion joints can extend the length of the blocking device to block the leaks.

[0158] The usage method of this embodiment is as follows:

[0159] In actual operation, the blocking device is placed inside the gas pipeline, and the regulating component 310 is activated by the control component 620. The regulating component 310 can make the moving component 270 abut against the inner wall of the gas pipeline.

[0160] The control unit 620 starts the drive unit 230, which can drive the moving part 270 to rotate, thereby allowing the blocking device to move to the corresponding leak point in the gas pipeline.

[0161] According to the location of the gas pipeline leak point, the control unit 620 activates the first telescopic member and the second telescopic member to adjust the position of the first blocking member 410 and the second blocking member 510, so that the area between the first blocking member 410 and the second blocking member 510 can cover the gas pipeline leak point.

[0162] The control unit 620 activates the first inflation unit 420, the first valve body 430, the second inflation unit 520, and the second valve body 530, causing the first blocking unit 410 and the second blocking unit 510 to expand, thereby blocking both ends of the leak point and facilitating subsequent maintenance by maintenance personnel.

[0163] The advantage of this embodiment is that, by setting a first telescopic component and a second telescopic component, when there are two similar leak points in the gas pipeline, the first telescopic component and the second telescopic component can extend the length of the blocking device, thereby blocking the leak points and further improving applicability.

[0164] Example 3

[0165] This embodiment relates to the blocking system of this utility model.

[0166] A gas pipeline blocking system is characterized by comprising a blocking device and a detection device as described in Embodiments 1 and 2. The detection device is disposed outside the gas pipeline and is used to detect leaks in the gas pipeline and transmit the location information to the blocking device.

[0167] It should be noted that the detection device includes an infrared transmitter and an infrared receiver. The infrared transmitter is installed on the outside of the gas pipeline and performs real-time detection of the gas pipeline. When a leak is detected in the gas pipeline, the infrared transmitter generates a signal. The infrared receiver is integrated into the control component 600 of the blocking device and can receive the signal from the infrared transmitter, thereby causing the blocking device to move to the leak location.

[0168] The usage method and advantages of this embodiment are the same as those of Embodiments 1 and 2, and will not be repeated here.

[0169] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0170] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
