[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In related technologies, wire diameter measurement products are designed with reference to vernier calipers, and require manual reading and recording, which is prone to reading and recording deviations. It is necessary to manually climb to the middle of the pole tower and operate at a distance of about 2 meters from the line. The mechanical vernier caliper has fine markings, which makes it difficult to read in a high-altitude environment.

[0026] like Figures 1 to 3As shown, an embodiment of the present invention provides an overhead line diameter measuring device, which includes a mounting seat 2, a fixed contact rod 201, a stroke measuring member 203 and a communication member 204. The fixed contact rod 201 is arranged on the mounting seat 2, and the movable contact rod 202 is arranged on the mounting seat 2 opposite to the fixed contact rod 201. The movable contact rod 202 is movably arranged relative to the mounting seat 2. A line-passing protrusion 2021 is arranged on the side of the movable contact rod 202 facing the fixed contact rod 201. An incoming line interval and an outgoing line interval are provided between the movable contact rod 202 and the fixed contact rod 201. The incoming line interval is located on the side of the line-passing protrusion 2021 away from the mounting seat 2, and the outgoing line interval is located on the side of the line-passing protrusion 2021 facing the mounting seat 2. The stroke measuring member 203 is arranged between the mounting seat 2 and the movable contact rod 202 to detect the movement stroke of the movable contact rod 202. The communication member 204 is connected to the stroke measuring member 203 by signal to output the measurement peak value of the stroke measuring member 203.

[0027] The overhead line diameter measuring device provided in this embodiment is applied, and the overhead line diameter measuring device includes a mounting seat 2, a fixed touch rod 201, a stroke measuring component 203 and a communication component 204. When the line to be measured moves in a direction close to the mounting seat 2 within the line-entry interval, the line to be measured drives the movable touch rod 202 away from the fixed touch rod 201, and then the line to be measured passes through the line-passing protrusion 2021. When the line to be measured moves in a direction away from the mounting seat 2 within the line-exit interval, the line to be measured drives the movable touch rod 202 away from the fixed touch rod 201. During this process, the stroke measuring component 203 is arranged between the mounting seat 2 and the movable touch rod 202 to detect the movement stroke of the movable touch rod 202. The communication component 204 is connected to the stroke measuring component 203 signal to output the measurement peak value of the stroke measuring component 203, that is, the line diameter detection result of the line to be measured. There is no need to manually climb the tower to read the readings, thereby reducing the difficulty and risk factor of operation.

[0028] like Figure 1 and Figure 3 As shown, the movable contact rod 202 includes a movable rod and a guide rod 2022. The movable rod is movably arranged on the mounting seat 2. The guide rod 2022 is arranged at one end of the movable rod away from the mounting seat 2. The guide rod 2022 is arranged at an angle with the movable rod. The middle part of the guide rod 2022 protrudes toward the direction close to the fixed contact rod 201 to form a line-passing convex portion 2021. When the line to be tested moves toward the direction close to the mounting seat 2 in the line-entry interval, the line to be tested and the guide rod 2022 slide together to drive the movable contact rod 202 away from the fixed contact rod 201, and then the line to be tested passes through the line-passing convex portion 2021. When the line to be tested moves toward the direction away from the mounting seat 2 in the line-exit interval, the line to be tested and the guide rod 2022 slide together to drive the movable contact rod 202 away from the fixed contact rod 201.

[0029] like Figure 2 and Figure 3As shown, the guide rod 2022 includes a first oblique rod and a second oblique rod connected at an angle, the first oblique rod is located on the side of the second oblique rod away from the mounting seat 2, and the connection between the first oblique rod and the second oblique rod forms a line-passing protrusion 2021, the line-entry interval is set between the first oblique rod and the fixed touch rod 201, and the line-exit interval is set between the second oblique rod and the fixed touch rod 201. When the line to be tested moves in the direction close to the mounting seat 2 within the line-entry interval, the line to be tested and the first oblique rod are slidably matched to drive the movable touch rod 202 away from the fixed touch rod 201, and then the line to be tested passes through the line-passing protrusion 2021, and when the line to be tested moves in the direction away from the mounting seat 2 within the line-exit interval, the line to be tested and the second oblique rod are slidably matched to drive the movable touch rod 202 away from the fixed touch rod 201.

[0030] like Figure 3 As shown, the movable rod is swingably arranged on the mounting seat 2, and the swing axis of the movable rod is perpendicular to the fixed touch rod 201. When the line to be tested moves in the direction close to the mounting seat 2 within the line-in interval, the line to be tested and the guide rod 2022 are slidably matched to drive the movable rod to swing, so that the movable touch rod 202 is away from the fixed touch rod 201, and then the line to be tested passes through the line-passing protrusion 2021. When the line to be tested moves in the direction away from the mounting seat 2 within the line-out interval, the line to be tested and the guide rod 2022 are slidably matched, and the line to be tested drives the movable rod to swing, so that the movable touch rod 202 is away from the fixed touch rod 201.

[0031] In this embodiment, when the movement stroke of the movable contact rod 202 is zero, the movable rod is arranged at an angle relative to the fixed contact rod 201, and the movable rod gradually moves away from the fixed contact rod 201 in the direction away from the mounting seat 2. With the above structure, when the line to be tested moves in the direction close to the mounting seat 2 in the line-in interval, and when the line to be tested moves in the direction away from the mounting seat 2 in the line-out interval, the power required for the swing of the movable rod is reduced, thereby reducing the detection resistance.

[0032] like Figure 3 As shown, the stroke measuring member 203 includes a fixed member 2033, a movable member 2034, a detection element 2031 and a reset member. The fixed member 2033 is arranged on the mounting seat 2, and the movable member 2034 can be movably arranged on the fixed member 2033. The end of the movable member 2034 facing away from the fixed member 2033 abuts against the movable touch rod 202. The detection element 2031 is arranged between the fixed member 2033 and the movable member 2034 to detect the movable stroke of the movable member 2034. The communication member 204 is connected to the detection element 2031 by signal to output the measurement peak value of the detection element 2031. The reset member is arranged between the fixed member 2033 and the movable member 2034 to apply a reset force to the movable member 2034 to move in the direction close to the fixed touch rod 201.

[0033] like Figure 3As shown, a contact recess 2023 is provided on the side of the movable contact rod 202 away from the fixed contact rod 201, and the contact recess 2023 is provided corresponding to the line-crossing protrusion 2021, and one end of the movable member 2034 away from the fixed member 2033 is in contact with the contact recess 2023. When one end of the movable member 2034 away from the fixed member 2033 is in contact with the contact recess 2023, the movable member 2034 can be prevented from being separated from the movable contact rod 202 and the contact position between the movable member 2034 and the movable contact rod 202 can be prevented from changing during the movement of the movable contact rod 202.

[0034] like Figure 3 As shown, the overhead line diameter measuring device further includes a display screen 2032 disposed on the mounting base 2 , and the display screen 2032 is signal-connected to the stroke measuring member 203 to display the detection result of the stroke measuring member 203 .

[0035] like Figure 1 and Figure 2 As shown, the overhead line diameter measuring device further comprises an insulating rod 1 , and a mounting seat 2 is arranged on the upper part of the insulating rod 1 .

[0036] like Figure 3 As shown, the mounting base 2 includes a detachably connected front protective cover 205 and a rear protective cover 206, the front protective cover 205 and the rear protective cover 206 are arranged to form a protective cavity, and the stroke measuring component 203 and the communication component 204 are both arranged in the protective cavity, so as to facilitate the assembly and maintenance of the stroke measuring component 203 and the communication component 204 in the protective cavity.

[0037] like Figure 3 As shown, the travel measuring component 203 and the communication component 204 are both arranged on the rear protective cover 206 , and the front protective cover 205 is provided with an escape opening 2055 , and the communication component 204 extends into the escape opening 2055 .

[0038] like Figure 3 As shown, the mounting base 2 also includes a first clamping plate 2051, a second clamping plate 2061 and a fastener. The first clamping plate 2051 and the second clamping plate 2061 are respectively arranged on both sides of the fixed touch rod 201, the first clamping plate 2051 is connected to the front protective cover 205, and the second clamping plate 2061 is connected to the rear protective cover 206. The fastener is penetrated by the first clamping plate 2051, the second clamping plate 2061 and the fixed touch rod 201, and the fastener is respectively connected to the first clamping plate 2051, the second clamping plate 2061 and the fixed touch rod 201, so as to facilitate the quick and reliable installation of the mounting base 2.

[0039] Specifically, when in use, hold the insulating rod 1, lift the mounting base 2 fixedly installed on the insulating rod 1, place the fixed contact rod 201 on the overhead power transmission line, and slowly push the insulating rod 1 upward, so that the overhead power transmission line slides downward along the fixed contact rod 201 to the incoming line interval and touches the guide rod 2022 of the movable contact rod 202. As the insulating rod 1 continues to be pushed upward, the movable contact rod 202 is pushed open by the overhead power transmission line, causing the movable contact rod 202 to rotate around the axis 2024, and the line-passing protrusion 2021 leaves the fixed contact rod 201, abuts the recessed portion 2023 to push the movable part 2034 of the stroke measuring part 203 backward, and the detection element 2031 starts to measure values. When the overhead wire reaches the highest point position of the line-passing protrusion 2021, the detection element 2031 measures a measurement peak value, and this measurement peak value is the diameter of the overhead power transmission line. The measured peak value can be directly read out through the display screen 2032 on the stroke measurement component 203, or the data can be transmitted to the operator's mobile phone applet through the communication component 204 using Bluetooth connection.

[0040] When measuring the diameter of overhead power lines in the distribution network, it is possible to avoid climbing and work with power on. The device is designed with a wireless data transmission function, which can transmit the measured data in real time to a mobile phone or computer connected to the network, and can quickly and accurately form records, avoiding errors that may occur when manually entering measured values.
