TECHNICAL FIELD

[0002] Line loss is voltage or electric energy consumed by resistance, and the cross-sectional area and length of the wire determine the amount of resistance, and the current determines the amount of voltage or electric energy loss. The greater the current, the more voltage loss, the greater the electric energy loss, and the longer the time, the more electric energy loss. In the process of electric energy transmission, power transformation and power distribution, the loss caused by the components of the power system (such as resistance, inductance, etc.) involves many aspects in actual management, including the structure of the power grid, the metering equipment, the substation, electricity theft and leakage.

In the process of implementing the present application, the inventor found that the existing technology has at least the following problems which have not been solved: the device holds the cable with the line loss detection head, can be moved, processes information through the line loss detection host, and displays the detection situation through the detection data display screen, so as to facilitate the master of the line loss situation. However, the length of the existing cable is not uniform, and when the user needs to detect a longer cable, the user needs to hold the device and move for a long time, which is time-consuming and laborious to operate.

[0018] A use method of a line loss detection adjustable positioning device, comprising the following steps:

[0019] S1: when the user uses the device to detect the surface of the cable, the left and right clamp rings are simultaneously opened and clamped on the cable to be detected, and then the left and right clamp rings are simultaneously closed to become annular, at this time the electric telescopic rod is in a retracted state, the hinge column at the folding part of the right folding plate is inserted into the sleeve ring, then the user rotates the folding plate by hand to drive the arc-shaped inner ring teeth in the left and right clamp rings to rotate clockwise, drives the driven gear in the half-ring groove to rotate clockwise, so that the twelve tooth plates move to the center axis of the arc-shaped inner ring teeth to abut against the surface of the cable;

[0020] And because the surface of the cable of different diameters is different in curvature; when the curvature of the surface of the cable is large, the balls on the round rods on both sides of the folding plate first come into contact with the surface of the cable, and when the contact force of the surface of the cable on both sides of the round rod gradually increases, both sides of the round rod move towards the direction close to the arc-shaped limiting slide rail, at this time the round rod close to the inner wall of the arc-shaped limiting slide rail of the folding plate slides in the arc-shaped limiting slide rail, and reduces the mutual distance therebetween, prompting the remaining round rods to move away from the arc-shaped limiting slide rail, ensuring that the round rods with balls embedded on the folding plate are in contact with the surface of the cable, and the one-way roller at one end of the spring contraction rod synchronously contacts the surface of the cable and contracts, at this time the second spring extension rod is elongated to keep the transmission belt in a taut state, ensuring that the subsequent device moves stably on the cable and detects the cable, and vice versa.

[0021] S2: When the arc-shaped inner ring teeth rotate clockwise in the half-ring groove, the rear arc-shaped inner ring teeth are inserted into the upper two limiting plates, and the front arc-shaped inner ring teeth are inserted into the lower two limiting plates, then the rotating contact bolt is turned to fix the left and right clamping rings into a ring body to avoid the rotation of the arc-shaped inner ring teeth in the half-ring groove, at this time, after the device is positioned on the cable to be detected, the detection machine is started, and the magnet on the extension rod moves synchronously with the iron block to the center axis of the half-ring groove and is attached to the surface of the cable.

[0022] Then the electric telescopic rod is elongated, and because the one-way roller on the right clamping ring contacts the surface of the cable and cannot rotate clockwise, the left clamping ring moves left under the leftward thrust of the electric telescopic rod, at this time the one-way roller outer ring in the left clamping ring rotates counterclockwise, drives the spiral groove rod to rotate counterclockwise, and promotes the six inner tooth arc plates to move left and rotate counterclockwise synchronously with the extension rod and the detection machine, so as to detect the surface of the cable, then the electric telescopic rod is retracted, at this time the one-way roller outer ring in the left clamping ring cannot rotate clockwise, so that the right clamping ring on the right side moves left and drives the detection machine on the side to detect the cable again.

[0023] S3: Because the left six tooth plates and the right six tooth plates are staggered, when the round rods on one end of the tooth plates are staggered and attached to the surface of the cable, when the balls on the round rods roll to the area where the cable is thickened due to aging, they will stop rolling on the surface of the cable due to the resistance of the cable, i.e. reminding the user that the cable at this position is aging, and avoiding the detection machine contacting the aging area of the cable.

[0024] The present application has the following beneficial effects:

[0025] 1. In this invention, when the curvature of the cable surface is large, the balls on the round rods on both sides of the folding plate first contact the surface of the cable. As the contact force between the round rods on both sides and the surface of the cable gradually increases, the round rods on both sides move towards the arc-shaped limiting slide rail. At this time, the round rods on the folding plate that are close to the inner wall of the arc-shaped limiting slide rail slide within the arc-shaped limiting slide rail and reduce the distance between them, causing the remaining round rods to move away from the arc-shaped limiting slide rail. This ensures that the round rods with embedded balls on the folding plate are in contact with the surface of the cable. At the same time, the one-way roller at one end of the spring retraction rod follows the round rod to contact and retract the surface of the cable. At this time, the second spring telescopic rod extends to make the transmission belt taut, ensuring that the subsequent device moves stably on the cable and detects the cable, ensuring that the device can be positioned on cables of different diameters.

[0026] 2. In this invention, by simultaneously opening and locking the left and right clamping rings onto the cable to be tested, rotating the folding plate causes the arc-shaped inner ring teeth inside the left and right clamping rings to rotate clockwise, which in turn causes the driven gear in the semi-annular groove to rotate clockwise. This causes the twelve toothed plates to move toward the central axis of the arc-shaped inner ring teeth, making contact with the surface of the cable. When the arc-shaped inner ring teeth rotate clockwise in the semi-annular groove, the rear arc-shaped inner ring teeth are inserted into the two upper limiting plates, and the front arc-shaped inner ring teeth are inserted into the two lower limiting plates. Then, rotating the contact bolt fixes the left and right clamping rings into a ring, completing the operation of positioning the device on the cable to be tested. The operation is simple and convenient.

[0027] 3. In this invention, as the electric telescopic rod extends, the left clamp ring moves to the left due to the leftward thrust of the electric telescopic rod. At this time, the outer ring of the one-way roller inside the left clamp ring rotates counterclockwise, which, together with the transmission belt, drives the spiral groove rod to rotate counterclockwise. This causes the six internal toothed arc plates to move the telescopic rod and the testing machine to move to the left and rotate counterclockwise simultaneously, thus inspecting the surface of the cable. Similarly, the right clamp ring on the right side moves to the left and drives the testing machine on its side to perform a second inspection of the cable. This ensures that the device can perform more accurate ring inspection of the cable, and the device is convenient for automatically inspecting longer cables, saving time and effort.

[0028] 4. In this invention, the six toothed plates on the left and the six toothed plates on the right are staggered. When the round rods on one end of the toothed plates are staggered and in contact with the surface of the cable, when the ball bearings on the round rods roll to the area of ​​the cable that has thickened due to aging, they will stop rolling on the surface of the cable due to the resistance of the cable. This reminds the user that the cable is aging and avoids the testing machine from contacting the area of ​​the cable that is aging, reducing the possibility of damage to the testing head of the testing machine and ensuring the service life of the testing machine.

[0052] The use method and advantages of the present application are as follows:

[0053] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 ,

[0054] S1: When the user uses the device to detect the surface of the cable, the left and right clamp rings 2 and 3 are simultaneously opened and clamped on the cable to be detected, and then the left and right clamp rings 2 and 3 are simultaneously closed to become annular, at this time the electric telescopic rod 1 is in the retracted state, the hinge column at the folding part of the right folding plate 43 is inserted into the sleeve ring 7, then the user rotates the folding plate 43 by hand to drive the arc-shaped inner ring teeth 44 in the left and right clamp rings 2 and 3 to rotate clockwise, drives the driven gear 45 in the half-ring groove 41 to rotate clockwise, and moves the twelve toothed plates 46 to the center axis of the arc-shaped inner ring teeth 44 to resist the surface of the cable.

[0055] And because the surface of the cable of different diameter has different curvature; when the curvature of the cable surface is larger, the ball 63 on the round rod 62 on both sides of the folding plate 61 first collides with the surface of the cable, when the collision force of the cable surface of both sides of the round rod 62 gradually increases, both sides of the round rod 62 moves to the direction close to the arc-shaped limiting slide rail 47, at this time the round rod 62 close to the inner wall of the arc-shaped limiting slide rail 47 of the folding plate 61 slides in the arc-shaped limiting slide rail 47, and reduces the mutual distance between them, prompting the remaining round rod 62 to move away from the arc-shaped limiting slide rail 47, ensuring that the round rod 62 embedded with the ball 63 on the folding plate 61 collides with the surface of the cable, and the one-way roller 55 at one end of the first spring contraction rod 54 synchronously collides with the surface of the cable and contracts, at this time the second spring extension rod 59 is elongated to make the transmission belt 57 in a tight state, ensuring that the subsequent device moves stably on the cable and detects the cable, and vice versa.

[0056] S2: when the arc-shaped inner ring teeth 44 rotate clockwise in the half-ring groove 41, the rear arc-shaped inner ring teeth 44 are inserted into the upper two limiting plates 48, and the front arc-shaped inner ring teeth 44 are inserted into the lower two limiting plates 48, then the rotating collision bolt 49 is turned, so that the left and right clamp rings 2 and 3 are fixed into a ring body to avoid the rotation of the arc-shaped inner ring teeth 44 in the half-ring groove 41, at this time the device is positioned on the cable to be detected, and then the detection machine 513 is started, because the magnet 512 on the extension rod 511 moves synchronously with the iron block 514 to the center axis of the half-ring groove 41 and is attached to the surface of the cable;

[0057] Then the electric telescopic rod 1 is elongated, because the one-way roller 55 on the right clamp ring 3 collides with the surface of the cable, and the one-way roller 55 cannot rotate clockwise, at this time the left clamp ring 2 is pushed to the left by the electric telescopic rod 1, at this time the outer circle of the one-way roller 55 in the left clamp ring 2 rotates counterclockwise, cooperates with the transmission belt 57 to drive the helical groove rod 56 to rotate counterclockwise, and promotes the six inner tooth arc plates 52 to drive the extension rod 511 and the detection machine 513 to move left synchronously and rotate counterclockwise, to detect the surface of the cable, then the electric telescopic rod 1 is retracted, at this time the outer circle of the one-way roller 55 in the left clamp ring 2 cannot rotate clockwise, and then the right clamp ring 3 on the right side moves left and drives the detection machine 513 on the side to detect the cable again;

[0058] S3: because the left and right six tooth plates 46 are staggered, when the round rod 62 on one end of the tooth plate 46 is staggered and attached to the surface of the cable, when the ball 63 on the round rod 62 rolls to the area where the cable is thickened due to aging, it will stop rolling on the surface of the cable due to the resistance of the cable, that is, it reminds the user that the cable at this place is aging, and avoids the contact between the detection machine 513 and the aging area of the cable.

[0059] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any changes or replacements within the technical scope disclosed by the present application, which can be easily thought by any person skilled in the art, should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.

7. The method of using the line loss detection adjustable positioning device of any of claims 3-6, wherein, The steps include: S1: when the user uses the device to detect the surface of the cable, the left and right clamp rings (2) and (3) are simultaneously opened and sleeved on the cable to be detected, and then the left and right clamp rings (2) and (3) are simultaneously closed to become annular, at this time the electric telescopic rod (1) is in a retracted state, the hinge column at the folding part of the right folding plate (43) is inserted into the sleeve ring (7), then the user rotates the folding plate (43) by hand to drive the arc-shaped inner ring teeth (44) in the left and right clamp rings (2) and (3) to rotate clockwise, drives the driven gear (45) in the half-ring groove (41) to rotate clockwise, and moves the twelve tooth plates (46) to the center axis of the arc-shaped inner ring teeth (44) to abut against the surface of the cable; Because the surface of the cable with different diameters has different curvature, when the curvature of the cable surface is large, the ball (63) on the round rod (62) on both sides of the folding plate (61) first collides with the surface of the cable. When the collision force of the round rod (62) on both sides on the surface of the cable gradually increases, the round rod (62) on both sides moves towards the direction close to the arc-shaped limiting slide rail (47). At this time, the round rod (62) close to the inner wall of the arc-shaped limiting slide rail (47) on the folding plate (61) slides in the arc-shaped limiting slide rail (47) and reduces the mutual distance therebetween, prompting the remaining round rod (62) to move away from the arc-shaped limiting slide rail (47), ensuring that the round rod (62) with the ball (63) embedded on the folding plate (61) collides with the surface of the cable. At the same time, the one-way roller (55) at one end of the first spring telescopic rod (54) collides with the surface of the cable synchronously and shrinks. At this time, the second spring telescopic rod (59) is elongated to make the transmission belt (57) in a tight state, ensuring that the subsequent device moves stably on the cable and detects the cable. Conversely, the same effect can be achieved. S2: When the arc-shaped inner ring teeth (44) rotate clockwise in the half-ring groove (41), the rear arc-shaped inner ring teeth (44) are inserted into the upper two limiting plates (48), and the front arc-shaped inner ring teeth (44) are inserted into the lower two limiting plates (48). Then, the rotating collision bolt (49) is turned to fix the left clamp ring (2) and the right clamp ring (3) into a ring body to avoid the rotation of the arc-shaped inner ring teeth (44) in the half-ring groove (41). At this time, after the device is positioned on the cable to be detected, the detection machine (513) is started. Because the magnet (512) on the telescopic rod (511) moves synchronously with the iron block (514) to the center axis of the half-ring groove (41) and is attached to the surface of the cable. Then, the electric telescopic rod (1) is elongated. Because the one-way roller (55) on the right clamp ring (3) collides with the surface of the cable and cannot rotate clockwise, the left clamp ring (2) moves to the left under the leftward thrust of the electric telescopic rod (1) at this time. The outer circle of the one-way roller (55) in the left clamp ring (2) rotates counterclockwise. The transmission belt (57) drives the helical groove rod (56) to rotate counterclockwise, prompting the six inner tooth arc plates (52) to drive the telescopic rod (511) and the detection machine (513) to move left synchronously and rotate counterclockwise to detect the surface of the cable. Then, the electric telescopic rod (1) is retracted. At this time, the outer circle of the one-way roller (55) in the left clamp ring (2) cannot rotate clockwise, and the right clamp ring (3) on the right side moves left and drives the detection machine (513) on the side thereof to detect the cable again. S3: Because the six toothed plates (46) on the left and the six toothed plates (46) on the right are staggered, when the round bars (62) on one end of the toothed plates (46) are staggered and fit the surface of the cable, when the balls (63) on the round bars (62) roll to the area where the cable is thickened due to aging, the resistance of the cable will stop the balls (63) from rolling on the surface of the cable, that is, it reminds the user that the cable is aging at this point, and avoids the detection machine (513) from contacting the aged area of the cable.
