Description

Technical Field

[0001] The utility model relates to the technical field of power measurement, in particular to a power measurement device. Background Art

[0002] Measuring the length of electrical wires is a common task in power engineering. The most common method is direct measurement, which uses a tape measure or measuring instrument to measure the length of the wire directly. Before measuring, the wire must be straightened to avoid bends and twists. Then, align the starting point of the tape measure or measuring instrument with the starting point of the wire and measure along the wire section by section until the end point is reached. Finally, the measured values for each section are added together to determine the total length of the wire.

[0003] The prior art publication number CN221124660U is a high-precision measuring device for electric power engineering, comprising a support assembly including a workbench and a rotating shaft rotatably connected to the upper surface of the workbench; and a moving assembly arranged on the top of the support assembly.

[0004] The device can straighten and measure wires to ensure the measurement results. However, in actual application, due to its structural limitations, it can only perform auxiliary straightening and measurement operations on shorter wires. Once longer wires need to be measured, multiple sections of measurement are required and finally added together to obtain the final result. However, the entire detection process is relatively cumbersome, and since it is a multi-section measurement performed by manpower, errors are prone to occur, making it difficult to ensure the accuracy of the measurement results. For this reason, improvements are proposed. Utility Model Content

[0015] Furthermore, a controller is fixedly mounted on one side of the outer surface of the frame, and the controller is electrically connected to the encoder and the motor, which is conducive to controlling the overall operation.

[0016] Beneficial effects of the utility model:

[0031] Working principle:

[0032] Step 1: Place one end of the wire between the two V-shaped clamps 12 and contact the end with the slider 8. Then turn the knob 10, which drives the bidirectional screw 9 to rotate. The bidirectional screw 9 drives the two sliders 8 closer to each other, so that the two V-shaped clamps 12 are close to each other until the wire end is clamped. Then, the wire is straightened by manpower.

[0033] Step 2: Turn the handwheel 6, which drives the one-way screw 15 to rotate, thereby driving the movable seat 7 to descend along the slide rod 13. The movable seat 7 drives the V-shaped active roller 4 and the V-shaped detection roller 14 connected to it to descend until the V-shaped active roller 4 and the V-shaped auxiliary roller 2 cooperate to complete the compression and fixation of the wire. At this time, the contact point of the V-shaped detection roller 14 and the wire is at a set distance from the end point of the wire, which is also the basic measurement dimension;

[0034] Step 3: Use the bidirectional moving assembly to drive the two V-shaped clamps 12 to separate, release the fixation on the wire end, and then manually tilt the wire end;

[0035] Step 4: Start the motor 5, which drives the connected synchronous pulley 19 to rotate. The synchronous pulley 19 cooperates with the synchronous belt 18 to drive the other synchronous pulley 19 to rotate, thereby causing the two synchronous pulleys 19 to rotate, thereby driving the two V-shaped active rollers 4 to rotate. The V-shaped active roller 4 and the V-shaped auxiliary roller 2 cooperate to drive the wire to start moving. While the wire moves, the friction force drives the V-shaped detection roller 14 to rotate. The encoder 17 converts the angular displacement of the V-shaped detection roller 14 into an electrical signal, and then sends it to the controller 3, thereby achieving the purpose of measuring the length of the wire;

[0036] Step 5: When the encoder 17 loses its induction, the end of the wire is separated from the V-shaped auxiliary roller 2 and the V-shaped active roller 4 away from the mounting base 11. At this time, the unmeasured length of the wire end is the set length. The complete length of the wire can be obtained by adding the set end length to the measured length and the basic measurement size.
