Description

Technical Field

[0001] The utility model relates to the field of electric power measurement, in particular to a cable bending arc measuring device. Background Art

[0002] Excessive bending of cables can cause many problems. First, due to the reduction in the cross-sectional area through which the current passes, excessive heating will be generated, which may cause local thermal damage and structural damage inside the cable. In addition, the insulation performance of the cable is damaged, which may cause partial discharge of the cable, which will bring risks to the safe operation of the power grid. The problem with visually determining the bending radius of the cable is that it is highly dependent on the experience and subjective judgment of the employees. This method is easily affected by the subjective views and errors of different workers, so there is a large error.

[0003] However, in the prior art, the cable bending curvature measuring device includes an operating rod, a connector, an arc ruler, a bolt, a nut, and a rubber anti-slip layer. During use of the device, the threaded self-locking clamp is designed with a special thread structure so that the clamp can automatically lock after clamping the cable. Once the clamp clamps the cable and rotates to a specific position, the shape of the thread locks the clamp in a specific direction and cannot move freely. Therefore, when measuring the cable, the pressure sensor cannot be exerted by the force of the cable itself. When the cable is bent, it will be subjected to forces in different directions, resulting in a large deviation in the detection of the cable bending curvature. Utility Model Content

[0004] In order to remedy the above deficiencies, the utility model provides a cable bending curvature measuring device, which aims to improve the problem that a fixed cable cannot be subjected to a single restriction when being fixed, resulting in the inability to apply pressure to a pressure sensor through its own force when bending, leading to a large deviation in the detection of the cable bending curvature. In the prior art, manual visual inspection is usually used to detect the cable, resulting in a high error in the detection of the cable.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cable bending curvature measuring device, comprising a base, a display screen is fixedly connected to one side of the top of the base, an arc ruler is displayed on the front side of the display screen, a motor is fixedly connected to the front side of the base, a driving gear is fixedly connected to the output end of the motor, two connecting rods are rotatably connected inside the base, the lower ends of the two connecting rods are respectively fixedly connected to a driven gear and a transmission gear on the left and right sides, an auxiliary gear is rotatably connected inside the front side of the base, connecting plates are fixedly connected to the opposite sides of the connecting rods, rotating wheels are rotatably connected to the opposite sides of the two connecting plates, fixed half rings are rotatably connected to the upper sides of the two connecting plates, fixed components are fixedly connected to the front sides of the two connecting plates, and a detection component is fixedly connected to the upper side of the base.

[0011] Furthermore, the detection component includes a fixed block, the lower side of which is fixedly connected to the inside of the upper side of the base, a pressure sensor is fixedly connected to the inside of the lower side of the fixed block, a bolt is threadedly connected to the upper side of the fixed block, and a fixed plate is rotatably connected to the lower side of the bolt.

[0012] As a further description of the above technical solution:

[0013] By placing the cable on the upper side of the pressure sensor on the lower side of the inner wall of the fixed block, and then turning the bolt to drive the rotating fixed plate on the lower side to move downward, the cable is restricted to the upper side of the pressure sensor. When detecting bending, the pressure released by the cable can be concentrated on the upper side of the pressure sensor for accurate detection.

[0015] As a further description of the above technical solution:

[0016] The driving gear drives the driven gear to rotate, and drives the auxiliary gear to rotate. At the same time, the auxiliary gear is engaged with the transmission gear to rotate the rotation between the transmission gear and the driven gear to the adjacent side. The driven gear and the transmission gear are fixedly connected to a rotating shaft in the middle part, wherein a connecting rod is fixed to the rear side of the rotating shaft, and the rotating shaft is rotatably connected to the inside of the rear side of the base, so as to facilitate the rotation of the connecting rod.

[0042] The driving gear 11 at the output end is driven to rotate by starting the motor 12, thereby driving the driven gear 10 and the auxiliary gear 13 meshing on the left and right sides to rotate, wherein the auxiliary gear 13 is meshed with the transmission gear 14, thereby driving the transmission gear 14 to rotate, thereby driving the driven gear 10 and the connecting rod 6 on the rear side of the transmission gear 14 to rotate inside the lower side of the base 3, and the cable is fixed in the bending area through the fixing component and the detection component to detect the bending curvature, wherein the qualification degree of the cable can be intuitively seen through the arc ruler 2 on the front side of the display screen 1.
