[0003] Pipeline circuit testing is used to evaluate and maintain the electrical system inside the pipeline, including cables, sensors and control lines. This process ensures the safe operation of the pipeline and promptly detects circuit faults, insulation damage or other potential problems to prevent energy loss, environmental risks and safety hazards. Testing usually involves the use of specialized equipment such as cable testers, insulation resistance testers and thermal imagers to evaluate the integrity of the circuit, the quality of the electrical connections and the operating status of the equipment inside the pipeline. Through these tests, the reliability and efficiency of the pipeline system can be ensured, while extending its service life and reducing long-term maintenance costs.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides a circuit fault detection device, which includes a walking component 100, including a frame member 101, an adjusting component 102 arranged on the frame member 101 and a moving component 103 arranged on the outer wall of the frame member 101; and a positioning component 200, including a connecting member 201 arranged inside the frame member 101 and a clamping member 202 arranged at one end of the connecting member 201; and, the frame member 101 is driven by the moving member 103 to detect the circuit.

[0031] Furthermore, by providing a frame member 101, the compressive strength of the entire structure can be improved. When the overall circuit fault detection device penetrates into the structure of various circuit pipes, it can maintain its stability and prevent the inspection unit 300 from being damaged by collision; by providing a moving member 200, the movement of the frame member 101 is facilitated, so that the circuit fault detection device can move along the setting direction of the power line.

[0032] The clamping member 202 is arranged at one end of the connecting member 201 for movable insertion of the power line; the inspection unit 300 is arranged at the other end of the connecting member 201; and the connecting member 201 is fixedly connected to the frame member 101.

[0033] In summary, the frame member 101 enters the interior of the pipe, and the circuit line to be inspected is positioned by the clamping member 202. When the moving member 103 drives the frame member 101 to move, the inspection unit 300 can inspect the circuit.

[0034] Example 2

[0035] Reference Figure 1 to Figure 5, which is the second embodiment of the present invention, is based on the previous embodiment, except that the frame 101 is moved by setting the wheel 103b, so as to perform all-round and step-by-step detection of the circuit line inside the pipeline, and the tension of the wheel 103b can be adjusted by moving the movable block 102b, so as to adapt to the internal circuit detection of pipelines with different diameters, thereby expanding the scope of use of the equipment.

[0036] Specifically, the frame member 101 includes a first ring 101a and a second ring 101c which are spaced apart from each other, a third ring 101b is arranged between the first ring 101a and the second ring 101c, and outer walls of the first ring 101a, the second ring 101c and the third ring 101b are all provided with mounting blocks 101a-1.

[0037] Preferably, a support column 101a-11 is provided on the mounting block 101a-1, and the first circular ring 101a, the second circular ring 101c and the third circular ring 101b are fixedly connected by the support column 101a-11.

[0038] It is further explained that the frame member 101 is cylindrical, and three support columns 101a-11 are arranged at intervals along the circumferential direction of the first ring 101a, the second ring 101c, and the third ring 101b to enhance the overall stability.

[0039] Preferably, the first circular ring 101a, the second circular ring 101c and the third circular ring 101b are further provided with fixing blocks 101a-2, and the adjusting member 102 includes a limiting column 102a provided between two adjacent fixing blocks 101a-2.

[0040] Preferably, a movable block 102b is provided on the limiting column 102a, a through hole 102b-1 is opened on the movable block 102b, and the through hole 102b-1 is movably matched with the limiting column 102a, an elastic member 102c is sleeved on the limiting column 102a, and the elastic member 102c is located between the movable block 102b and the third ring 101b, and a fixed plate 102b-2 is provided on the movable block 102b.

[0041] The limiting column 102a is used to limit the moving direction of the movable block 102b; three fixed blocks 101a-2 are evenly arranged on the first circular ring 101a, the second circular ring 101c, and the third circular ring 101b.

[0042] It should be further supplemented that the elastic member 102c is preferably a compression spring.

[0043] The movable block 102b can move on the limit column 102a and can be fixed at any position of the limit column 102a. For the position adjustment and fixation of the movable block 102b, manual sliding adjustment can be performed and the movable block 102b can be fixed at the pre-stop position of the limit column 102a with bolts. It can also be adjusted by automatic control, such as a cylinder pushing the movable block 102b to move and stop at the pre-stop position, etc., to perform moving and positioning. The specific implementation means of this method is conventional technology and will not be elaborated in this case.

[0044] Preferably, an extension block 101a-21 is provided on the outer wall of the fixed block 101a-2 located on the first ring 101a and the second ring 101c, and the movable member 103 includes a first connecting rod 103a movably connected to the extension block 101a-21, a wheel 103b is provided at one end of the first connecting rod 103a, a second connecting rod 103c is movably provided between the first connecting rod 103a and the fixed plate 102b-2, a rotating shaft 103b-1 is provided at the center of the wheel 103b, and a ratchet 103b-11 is provided on the outer wall of the rotating shaft 103b-1.

[0045] Among them, three wheels 103b are arranged at equal intervals in the front and rear, so that the wheels 103b can be evenly attached to the inner wall of the pipe, so that they can move stably inside the pipe and are not easy to fall off.

[0046] The frame member 101 is provided with a control motor for driving the wheel 103b to rotate. The control motor is in communication connection with the control module 301, so that the overall circuit fault detection device can move along the setting direction of the power line.

[0047] Furthermore, when the current monitoring module 302 detects that an abnormal circuit situation occurs, it sends an electrical signal to the control module 301, and then the control module 301 sends an electrical signal to the control motor to shut down the speed of the control motor, so that the frame member 101 stops at the fault position, which is conducive to quickly locating the faulty circuit section on the power line.

[0048] By changing the position of the movable block 102b, the second connecting rod 103c will rotate relatively, thereby driving the first connecting rod 103a, so that the tension of the wheel 103b can be adjusted to adapt to pipelines within a certain diameter range.

[0049] Preferably, a mounting plate 103d is provided on the first connecting rod 103a, a pawl 103d-1 is movably provided on the mounting plate 103d, and the pawl 103d-1 is movably matched with the ratchet 103b-11.

[0050] The pawl 103d-1 is also provided with a lever 103d-11 to facilitate the operation of the staff and cancel the coordination between the ratchet wheel 103b-11 and the pawl 103d-1, thereby facilitating the subsequent maintenance work on the wheel 103b.

[0051] When the wheel 103b rolls, the shaft 103b-1 will rotate, and a ratchet 103b-11 is arranged on the shaft 103b-1 to cooperate with the pawl 103d-1, so that the wheel 103b can rotate in one direction. That is to say, when the circuit fault detection device needs to move in the pipeline, this arrangement can prevent the wheel 103b from reversing in an inclined place, adapt to a variety of pipeline environments, and enable it to move forward stably.

[0052] In addition, the cooperation between the ratchet 103b-11 and the pawl 103d-1 can increase the friction between the wheel 103b and the inner wall of the pipe. When there is oil or other lubricants on the inner wall of the pipe, it can reduce the occurrence of slippage to a certain extent, and can also make the wheel 103b move evenly, making the detection and analysis data more accurate.

[0053] Preferably, the connecting member 201 includes an assembly plate 303a disposed inside the third ring 101b, and the clamping member 303a includes a mounting frame 202a connected to the assembly plate 303a, and a clamping claw 202b is provided on the mounting frame 202a.

[0054] The arrangement of the clamping jaws 202b facilitates the overall circuit fault detection device to be hooked on the power line.

[0055] The assembly plate 303a is fixedly connected to the third ring 101b, and the circuit fault detection device is placed in the pipeline. The circuit line passes through the first ring 101a, the second ring 101c and the third ring 101b. The circuit line will be positioned by the clamp 202b, and after moving, the set inspection unit 300 will perform fault detection.

[0056] In summary, before testing the internal circuit of the pipeline, the position of the movable block 102b can be adjusted according to the condition of the pipeline, thereby adjusting the tension of the wheel 103b so that it can fit the inner wall of the pipeline, and through the cooperation of the ratchet 103b-11 and the pawl 103d-1, accidental reversal can be prevented during the forward process.

[0057] Example 3

[0058] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention, and this embodiment provides a test system, which includes a test unit 300, which includes a control module 301, a current monitoring module 302, an alarm module 303 and a wireless module 304; the current monitoring module 302 is electrically connected to the power line, and the control module 301 is communicatively connected to the current monitoring module 302 and the alarm module 303 respectively.

[0059] The current monitoring module 302 includes a current sensor, a light-emitting diode, a light-guiding column and an optical fiber. The input circuit of the current sensor is arranged on the power line, the output circuit end of the current sensor is connected to the light-emitting diode, the light-emitting diode is connected to the optical path of the light-guiding column by means of an optical fiber, and the current sensor is communicatively connected to the control module 301. Thus, the current monitoring module 302 is a prior art and will not be elaborated on herein.

[0060] Preferably, the alarm module 303 includes an alarm device 303a and a warning light 303b, and the wireless module 304 includes a wireless receiver 304a and a wireless transmitter 304b.

[0061] The wireless receiver 304a and the wireless transmitter 304b use the NRF905 wireless transceiver chip; thus, the introduction of the wireless module 304 for information interaction not only reduces the technical dependence of the operator, but also improves work efficiency while reducing labor intensity; it should be noted that the wireless receiver 304a and the wireless transmitter 304b are existing technologies, and their specific structures and connection relationships are not described in detail here.

[0062] The alarm device 303a is a buzzer alarm; the buzzer alarm and the warning light 303b are also prior art, and their specific structures and connection relationships are not described in detail here.

[0063] In summary, by providing the inspection unit 300, when the moving member 103 drives the frame member 101 to move, the inspection unit 300 can detect the circuit line condition inside the pipeline and locate the fault point.
