Description

Technical Field

[0001] The present invention relates to the field of line loss detection, and in particular to a line loss segmentation acquisition and measurement device and a use method thereof. Background Art

[0002] Line loss refers to the loss of electrical energy along transmission lines, also known as line loss load. Causes of line loss primarily include aging insulation, metering failures, and power theft by consumers. Line loss is often used to assess the economic efficiency of power system operations and indirectly reflects the technical conditions and management level of power supply. Power supply companies are required to regularly monitor line loss on transmission lines.

[0003] Currently, when measuring the line loss of a cable, the operator selects sections on the outer wall of the cable and then measures the line loss on the outer wall of the cable. The operator determines the existence of line loss between sections of the cable based on the values ​​after the segmented measurement. However, the outer wall of the cable is prone to aging during long-term use, which can lead to cracks in the outer skin of the cable and uneven surfaces. When the outer wall of the cable is cracked and uneven, the line loss of the cable is greatly consumed. If the cracked and uneven parts of the outer wall of the cable are detected, the measured value will be more accurate.

[0004] When testing cable line loss using existing segmented line loss measurement instruments, it is unable to accurately detect cracks on the cable surface and the unevenness caused by the cracks, which results in inaccurate line loss measurements. Summary of the Invention

[0005] The purpose of the present invention is to provide a line loss segmentation acquisition measuring device and its use method, which can solve the problem of inaccurate cable line loss measurement values ​​and the inability to find a suitable measurement position in the prior art, and can improve work efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A line loss segmentation collection and measurement device includes a support frame, which is placed on a cable and slidingly cooperates with the cable. A measuring device is provided on the support frame, and the measuring device includes a casing, a rotating mechanism fixed to the casing, a resistance mechanism driven to rotate by the rotating mechanism, and a flexible test plate detachably arranged on the inner wall of the casing. The casing is used to surround the cable, and the two ends of the resistance mechanism are in close contact with the outer wall of the cable and the flexible test plate respectively. The rotating mechanism is used to drive the resistance mechanism to rotate around the outer wall of the cable. The flexible test plate is used to squeeze the flexible test plate and form a mark on the flexible test plate when one end of the resistance mechanism rotates around the outer wall of the cable and the other end appears a convex portion on the outer wall of the cable.

[0008] Furthermore, the rotating mechanism includes a driving motor, a driving rod and two groups of driving parts.

The two groups of driving parts are symmetrically arranged on the inner wall of the casing, and the two groups of driving parts are rotatably matched with the inner wall of the casing, and the interference mechanism is installed on the driving part.

[0009] Furthermore, the two groups of driving parts both include a first driving block, a second driving block, a first connecting frame, a second connecting frame, a first arc frame and a second arc frame. The first driving block and the second driving block are both arranged on the driving rod. An arc-shaped limit block is provided on the inner wall of the casing. The first arc frame and the second arc frame are symmetrically rotated and arranged on the inner wall of the casing, and the first arc frame and the second arc frame are rotatably matched with the arc limit block. One end of the first connecting frame is hingedly matched with the first arc frame, and the other end of the first connecting frame is hingedly matched with the first driving block. One end of the second connecting frame is hingedly matched with the second arc frame, and the other end of the second connecting frame is hingedly matched with the second driving block.

[0010] Furthermore, the interference mechanism includes a detection frame installed on the outer walls of the first arc frame and the second arc frame, and a detection device installed on the detection frame, the detection device includes a detection rod, a interference wheel and a interference spring, the detection frame is provided with a receiving groove, the detection rod is set in the receiving groove and slides with the receiving groove, the interference spring is sleeved on the detection rod, the two ends of the interference spring are respectively connected to the detection rod and the inner wall of the receiving groove, the interference wheel is rotatably set at the bottom of the detection rod, and the interference wheel serves as one end of the interference mechanism to interfere with the outer wall of the cable, and a interference head is provided on the top of the detection rod, and the interference head serves as the other end of the interference mechanism to contact the flexible test board.

[0011] Furthermore, the flexible test board is arranged in a circular shape, and a detachable port is provided on the flexible test board for straightening the flexible test board. A plurality of rubber protrusions are provided on the flexible test board, and the plurality of rubber protrusions are arranged on the outer wall of the flexible test board around the circumference of the flexible test board. A contact head is provided on the top of the detection rod, and the contact head is in contact with the rubber protrusion.

[0012] Furthermore, the first fixing frame is provided with a ring-shaped brush, and the brush conflicts with the outer wall of the cable, and the second fixing frame is provided with symmetrically arranged sliding members, and the two groups of sliding members each include a sliding plate, two pressure springs and a number of pulleys, the sliding plate is arranged on the inner wall of the second fixing frame, and the two ends of the two pressure springs are respectively connected to the sliding plate and the inner wall of the second fixing frame, and the several pulleys are rotatably arranged on the side wall of the second fixing frame, and the several pulleys are slidably matched with the cable, and the casing is fixedly connected to the inner wall of the second fixing frame.

[0013] A method for using the above-mentioned line loss segmentation acquisition and measurement device includes:

[0014] S1: When performing a cable loss segmentation test on a cable, the operator first places the first and second fixing brackets on the cable. The annular brush on the first fixing bracket moves across the outer wall of the cable, thereby removing impurities on the outer wall of the cable to prevent the measuring device from affecting the judgment of the measuring device when measuring the cable loss. The second fixing bracket then moves to drive the measuring device to move to the cable segmentation detection location. When the second fixing bracket moves, the pulley on the second fixing bracket will contact the outer wall of the cable through the setting of the pressure spring, thereby reducing the friction caused by the movement of the second fixing bracket.

[0015] S2: After the measuring device finishes measuring one end of the cable, the operator operates the second fixing frame to move toward the first fixing frame. The second fixing frame moves along the sliding groove of the first fixing frame via the slide, so that the second fixing frame is in close contact with the outer wall of the first fixing frame. The first fixing frame is then moved over the cable. This arrangement allows the measuring device to measure the cable loss in sections, ensuring that the second fixing frame moves the same distance each time.

[0016] S3: When measuring the line loss of the cable, the driving motor drives the driving rod to rotate, and the driving rod can drive the two sets of driving parts to rotate at the same time. The driving rod drives the first driving block and the second driving block to rotate at the same time. The rotation of the first driving block will pull the first connecting frame to move, and the rotation of the second driving block will pull the second connecting frame to move. At this time, the first connecting frame and the second connecting frame will simultaneously drive the first arc frame and the second arc frame to rotate in the casing, and the rotation range of the first arc frame and the second arc frame forms a ring. The rotation of the first arc frame and the second arc frame can drive the detection equipment to perform comprehensive detection and measurement around the outer wall of the cable. The arc limit block plays the role of limiting the first arc frame and the second arc frame. Through this setting, the outer wall of the cable can be effectively measured comprehensively, and the first driving block and the second driving block drive the first connecting frame and the second connecting frame to perform reciprocating motion. Therefore, during the test, the first arc frame and the second arc frame can drive the detection equipment to perform multiple measurements around the outer wall of the cable, thereby improving the measurement accuracy;

[0017] S4: When the first arc frame and the second arc frame move, they will drive the detection frame to move. When the detection frame moves, the interference wheel at the bottom of the detection rod will interfere with the outer wall of the cable. When the interference wheel contacts the outer wall of the cable, the interference head on the interference rod will contact the flexible test board. The interference head will contact the rubber protrusion on the flexible test board and push the rubber protrusion outward. Then, the flexible test board is removed from the casing and straightened. The height of the protrusion on the flexible test board can be intuitively observed, and then it can be determined whether a certain point or a certain part on the outer wall of the measured cable is convex. After the measurement, press the protrusion on the flexible test board to make the protrusion sink for the next measurement.

[0018] The present invention is designed with a resistance mechanism and a flexible test plate that are in close contact with the cable, so that the resistance mechanism can be driven to rotate around the outer wall of the cable when the rotating mechanism is in operation. When one end of the resistance mechanism rotates around the outer wall of the cable, the other end can squeeze the flexible test plate when a convex portion appears on the outer wall of the cable and form a mark on the flexible test plate. After the flexible test plate is removed from the casing, the flexible test plate can be straightened to intuitively observe the height of the convexity on the flexible test plate, and then it can be determined whether a certain point or a certain part on the outer wall of the measured cable is convex. The convex portion of the cable can be detected in a targeted manner to determine the line loss of the cable. Through this arrangement, the convex portion of the cable can be accurately and intuitively determined, thereby improving the working efficiency of cable detection. BRIEF DESCRIPTION OF THE DRAWINGS

The first driving block 41 and the second driving block 42 are both arranged on the driving rod 34. An arc-shaped limit block 32 is provided on the inner wall of the casing 31. The first curved frame 45 and the second curved frame 46 are symmetrically rotatably arranged on the inner wall of the casing 31, and the first curved frame 45 and the second curved frame 46 are rotatably matched with the arc limit block 32. One end of the first connecting frame 43 is hingedly matched with the first curved frame 45, and the other end of the first connecting frame 43 is hingedly matched with the first driving block 41. One end of the second connecting frame 44 is hingedly matched with the second curved frame 46, and the other end of the second connecting frame 44 is hingedly matched with the second driving block 42. When the cable 2 is subjected to line loss measurement, the driving motor 33 drives the driving rod 34 to rotate. The driving rod 34 can simultaneously drive the two groups of driving members 4 to rotate. The driving rod 34 drives the first and second curved frames 45 and 46 to rotate. The first driving block 41 and the second driving block 42 rotate at the same time. The rotation of the first driving block 41 will pull the first connecting frame 43 to move, and the rotation of the second driving block 42 will pull the second connecting frame 44 to move. At this time, the first connecting frame 43 and the second connecting frame 44 will simultaneously drive the first arc frame 45 and the second arc frame 46 to rotate in the casing 31, and the rotation range of the first arc frame 45 and the second arc frame 46 forms a ring. The rotation of the first arc frame 45 and the second arc frame 46 can drive the detection equipment 5 to perform comprehensive detection and measurement around the outer wall of the cable 2. The arc limit block 32 plays the role of limiting the first arc frame 45 and the second arc frame 46. Through this setting, the outer wall of the cable 2 can be effectively measured comprehensively, and the first driving block 41 and the second driving block 42 drive the first connecting frame 43 and the second connecting frame 44 to perform reciprocating motion. Therefore, during the test, the first arc frame 45 and the second arc frame 46 can drive the detection equipment 5 to perform multiple measurements around the outer wall of the cable 2, thereby improving the measurement accuracy.

[0032] In this embodiment, Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the interference mechanism includes a detection frame 47 installed on the outer wall of the first arc frame 45 and the second arc frame 46, and the two detection frames 47 are provided with a detection device 5, and the detection device 5 includes a detection rod 51, a interference wheel 53 and a interference spring 54. The detection frame 47 is provided with a receiving groove 471, and the detection rod 51 is set in the receiving groove 471 and slides with the receiving groove 471. The interference spring 54 is sleeved on the detection rod 51, and the two ends of the interference spring 54 are respectively connected to the detection rod 51 and the inner wall of the receiving groove 471. The interference wheel 53 is rotatably set at the bottom of the detection rod 51, and the interference wheel 53 is in contact with the cable 2.

[0033] The housing 31 is also provided with a detachable flexible test board 6, which is arranged in a circular shape and has a detachable port for straightening the flexible test board 6. The flexible test board 6 is provided with a plurality of rubber protrusions 61, which are arranged on the outer wall of the flexible test board 6 around the circumference of the flexible test board 6. The top of the detection rod 51 is provided with a contact head 52, which contacts and cooperates with the rubber protrusion 61.

[0034] When the first arc frame 45 and the second arc frame 46 move, the detection frame 47 will be driven to move. When the detection frame 47 moves, the contact wheel 53 at the bottom of the detection rod 51 will contact the outer wall of the cable 2. When the contact wheel 53 contacts the outer wall of the cable 2, the contact head 52 on the contact rod will contact the flexible test board 6. The contact head 52 contacts the rubber protrusion 61 on the flexible test board 6 and pushes the rubber protrusion 61 outward. Then, the flexible test board 6 is removed from the housing 31, and the flexible test board 6 is straightened to be visually checked. By observing the height of the protrusion on the flexible test board 6, it is determined that a certain point or a certain part on the outer wall of the measured cable 2 is protruding. The protruding part of the cable 2 can be detected in a targeted manner to determine the line loss of the cable 2. Through this setting, the protruding part of the cable 2 can be accurately and intuitively determined, thereby improving the working efficiency of the cable 2 detection. After the measurement, the protrusion on the flexible test board 6 can be pressed to make the protrusion sink for the next measurement. In this way, repeated measurement can be achieved, and the operation is convenient and quick.

[0035] In this embodiment, Figure 1 、 Figure 2 and Figure 3As shown, the support frame 1 includes a first fixing frame 7 and a second fixing frame 73, both of which are arranged on the cable 2, and a slide groove is provided on the first fixing frame 7, and a slide 74 that slides with the slide groove is provided on the second fixing frame 73; when the measuring device 3 finishes measuring one end of the cable 2, the operator operates the second fixing frame 73 to move toward the direction of the first fixing frame 7, and the second fixing frame 73 moves on the slide groove on the first fixing frame 7 through the slide 74, so that the second fixing frame 73 is tightly attached to the outer wall of the first fixing frame 7, and then the first fixing frame 7 is moved on the cable 2. Through this arrangement, the measuring device 3 can perform segmented measurement of the line loss of the cable 2, so that the distance of the second fixing frame 73 moving each time is equal.

[0036] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the first fixing frame 7 is provided with a ring-shaped brush 72, and the brush 72 conflicts with the outer wall of the cable 2, and the second fixing frame 73 is provided with symmetrically arranged sliding members 75, and the two groups of sliding members 75 each include a sliding plate 76, two pressure springs 77 and a plurality of pulleys 78, the sliding plate 76 is provided on the inner wall of the second fixing frame 73, and the two ends of the two pressure springs 77 are respectively connected to the sliding plate 76 and the inner wall of the second fixing frame 73, and the plurality of pulleys 78 are rotatably provided on the side wall of the second fixing frame 73, and the plurality of pulleys 78 are slidably matched with the cable 2, and the housing 31 is fixedly connected to the inner wall of the second fixing frame 73; when When performing a line loss segmentation test on the cable 2, the operator first places the first fixing frame 7 and the second fixing frame 73 on the cable 2. The annular brush 72 on the first fixing frame 7 moves through the outer wall of the cable 2, thereby removing impurities on the outer wall of the cable 2 to prevent the measuring device 3 from affecting the judgment of the measuring device 3 when measuring the line loss of the cable 2. Then, the second fixing frame 73 moves to drive the measuring device 3 to move, so that the measuring device 3 can move to the location of the cable 2 segment detection. When the second fixing frame 73 moves, the pulley 78 on the second fixing frame 73 will contact the outer wall of the cable 2 through the setting of the pressure spring 77, thereby reducing the friction caused by the movement of the second fixing frame 73.

[0037] The method of use and advantages of the present invention: The method of use of the line loss segmentation acquisition and measurement device has the following working process:

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown:

[0039] S1: When performing a line loss segmentation test on the cable 2, the operator first places the first fixing frame 7 and the second fixing frame 73 on the cable 2. The annular brush 72 on the first fixing frame 7 moves through the outer wall of the cable 2, thereby removing impurities on the outer wall of the cable 2 to prevent the measuring device 3 from affecting the judgment of the measuring device 3 when measuring the line loss of the cable 2. Then, the second fixing frame 73 moves to drive the measuring device 3 to move, so that the measuring device 3 can move to the section detection position of the cable 2. When the second fixing frame 73 moves, the pulley 78 on the second fixing frame 73 will contact the outer wall of the cable 2 through the setting of the pressure spring 77, thereby reducing the friction caused by the movement of the second fixing frame 73;

[0040] S2: After the measuring device 3 finishes measuring one end of the cable 2, the operator operates the second fixing frame 73 to move toward the first fixing frame 7. The second fixing frame 73 moves along the slide groove of the first fixing frame 7 via the slide 74, so that the second fixing frame 73 is in close contact with the outer wall of the first fixing frame 7. The first fixing frame 7 is then moved on the cable 2. This arrangement enables the measuring device 3 to measure the line loss of the cable 2 in sections, ensuring that the second fixing frame 73 moves the same distance each time.

[0041] S3: When measuring the line loss of the cable 2, the driving motor 33 drives the driving rod 34 to rotate. The driving rod 34 can simultaneously drive the two sets of driving parts 4 to rotate. The driving rod 34 drives the first driving block 41 and the second driving block 42 to rotate simultaneously. The rotation of the first driving block 41 will pull the first connecting frame 43 to move, and the rotation of the second driving block 42 will pull the second connecting frame 44 to move. At this time, the first connecting frame 43 and the second connecting frame 44 will simultaneously drive the first curved frame 45 and the second curved frame 46 to rotate in the housing 31, and the rotation range of the first curved frame 45 and the second curved frame 46 is formed. The first arc frame 45 and the second arc frame 46 are rotated to drive the detection device 5 to perform comprehensive detection and measurement around the outer wall of the cable 2. The arc-shaped limit block 32 serves as a limit for the first arc frame 45 and the second arc frame 46. This arrangement can effectively perform comprehensive measurement of the outer wall of the cable 2, and the first driving block 41 and the second driving block 42 drive the first connecting frame 43 and the second connecting frame 44 to perform reciprocating motion. During the test, the first arc frame 45 and the second arc frame 46 can drive the detection device 5 to perform multiple measurements around the outer wall of the cable 2, thereby improving the accuracy of the measurement.

[0042] S4: When the first arc frame 45 and the second arc frame 46 move, the detection frame 47 will be driven to move. When the detection frame 47 moves, the contact wheel 53 at the bottom of the detection rod 51 will contact the outer wall of the cable 2. When the contact wheel 53 contacts the outer wall of the cable 2, the contact head 52 on the contact rod will contact the flexible test board 6. The contact head 52 contacts the rubber protrusion 61 on the flexible test board 6 and pushes the rubber protrusion 61 outward. Then, the flexible test board 6 is removed from the housing 31, and the flexible test board 6 is straightened to be straight. The height of the protrusion on the flexible test board 6 can be observed, and then it can be determined that a certain point or a certain part on the outer wall of the measured cable 2 is protruding. The protruding part of the cable 2 can be detected in a targeted manner to determine the line loss of the cable 2. Through this setting, the protruding part of the cable 2 can be accurately and intuitively determined, thereby improving the working efficiency of the cable 2 detection. After the measurement, the protrusion on the flexible test board 6 can be pressed to make the protrusion sink for the next measurement. In this way, repeated measurement can be achieved, and the operation is convenient and quick.

[0043] The present invention has the following beneficial effects:

[0044] 1. In the present invention, when performing a segmented line loss test on a cable, the operator first places a first fixing bracket and a second fixing bracket on the cable. The annular brush on the first fixing bracket moves across the outer wall of the cable, thereby removing impurities on the outer wall of the cable to prevent the measuring device from affecting the judgment of the measuring device when measuring the line loss of the cable. The second fixing bracket then moves to drive the measuring device to move to the location of the cable segment detection. When the second fixing bracket moves, the pulley on the second fixing bracket will contact the outer wall of the cable through the arrangement of the pressure spring, thereby reducing the friction caused by the movement of the second fixing bracket.

[0045] 2. In the present invention, after the measuring device has finished measuring one end of the cable, the operator operates the second fixing frame to move toward the first fixing frame. The second fixing frame moves along the sliding groove of the first fixing frame via the slide, so that the second fixing frame is in close contact with the outer wall of the first fixing frame. The first fixing frame is then moved over the cable. This arrangement enables the measuring device to measure the cable loss in sections, ensuring that the second fixing frame moves the same distance each time.

[0046] 3. In the present invention, when measuring the line loss of the cable, the driving motor drives the driving rod to rotate, and the driving rod can simultaneously drive the two sets of driving parts to rotate, and the driving rod drives the first driving block and the second driving block to rotate at the same time. The rotation of the first driving block will pull the first connecting frame to move, and the rotation of the second driving block will pull the second connecting frame to move. At this time, the first connecting frame and the second connecting frame will simultaneously drive the first arc frame and the second arc frame to rotate in the casing, and the rotation range of the first arc frame and the second arc frame forms a ring. The rotation of the first arc frame and the second arc frame can drive the detection equipment to perform comprehensive detection and measurement around the outer wall of the cable, and the arc limit block plays the role of limiting the first arc frame and the second arc frame. Through this arrangement, the outer wall of the cable can be effectively measured comprehensively, and the first driving block and the second driving block drive the first connecting frame and the second connecting frame to perform reciprocating motion, and then during the test, the first arc frame and the second arc frame can drive the detection equipment to perform multiple measurements around the outer wall of the cable, thereby improving the measurement accuracy;

[0047] 4. In the present invention, when the first arc frame and the second arc frame move, the detection frame will be driven to move. When the detection frame moves, the interference wheel at the bottom of the detection rod will interfere with the outer wall of the cable. When the interference wheel contacts the outer wall of the cable, the interference head on the interference rod will contact the flexible test board. The interference head contacts the rubber protrusion on the flexible test board and pushes the rubber protrusion outward. Then, the flexible test board is removed from the casing and the flexible test board is straightened to visually observe the height of the protrusion on the flexible test board, and then it is determined whether a certain point or a certain part on the outer wall of the measured cable is protruding. The protruding part of the cable can be targeted for detection to determine the line loss of the cable. Through this setting, the protruding part of the cable can be accurately and intuitively determined, thereby improving the working efficiency of cable detection. After the measurement, the protrusion on the flexible test board can be pressed to make the protrusion sink for the next measurement. In this way, repeated measurement can be achieved, and the operation is convenient and fast.
