Air compressor cooling fan phase sequence detection device

Abstract

The utility model discloses a phase sequence detection device for a heat dissipation fan of an air compressor, comprising a workbench, an air compressor and a heat dissipation fan. The utility model is provided with a detection device, and a placement slot and a fixing seat are provided, so that a phase sequence meter can be placed beside the heat dissipation fan, thereby eliminating the need for manual hand-holding and relieving the fatigue of manual hand-holding for a long time. Through the cooperation of a fixing block and a supporting block, a detection line of the phase sequence meter is fixed, so that the vibration of the heat dissipation fan during operation prevents the joint from loosening, thereby affecting the detection effect. The adjustment block is pushed to move, and when the adjustment block moves, the movement of the clamping block is driven by the connecting block, so that the clamping block can cancel the fixing of the fixed block. The fixed block is pulled to cancel the fixing effect of the fixed block on the detection line, and the phase sequence meter can be taken out. Through this arrangement, the fixation of the phase sequence meter can be quickly canceled, and the removal is convenient, thereby improving the use efficiency.

Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a phase sequence detection device for a heat dissipation fan of an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. A phase sequence meter is a new type of detection instrument that can detect the phase sequence of three-phase voltages below 500V (including 100V and 380V) and high voltage levels of 3kV and above (including 10kV, 35kV, 110kV and 220kV), that is, detect the phase sequence of the three-phase voltage a, b, and c.

[0003] When using a phase sequence meter to detect the phase sequence of the cooling fan of an air compressor, a worker is usually required to hold the phase sequence meter and wait for the test. This method increases the fatigue of the worker's arm. At the same time, the cooling fan is prone to vibration during operation. The vibration is transmitted to the connection of the detection head, which is easy to cause looseness, resulting in detection interruption, increasing detection time, and thus reducing detection efficiency.

[0025] Here’s how it works:

[0026] First, before use, bring the phase sequence meter 43 to the cooling fan 3 that needs phase sequence detection and wait for detection;

[0027] Second, when in use, put the phase sequence meter 43 on the fixing seat 42 in the placement groove 41, pass the detection line of the phase sequence meter 43 through the fixing block 442 to connect with the detection head of the heat dissipation fan, then push the fixing block 442, the fixing block 442 moves to drive the inner right end groove of the fixing block 442 to move, when it moves to the left end of the clamping block 446, the spring 447 loses its force and releases elastic potential energy to push the clamping block 446 to move, so that the clamping block 446 moves into the groove, and the fixing block 442 can be fixed, the fixing of the detection line is completed, and the phase sequence meter 43 is used to detect the phase sequence of the heat dissipation fan 3;

When the clamping block 446 moves, it squeezes the spring 447. When the clamping block 446 moves, the fixing effect of the fixed block 442 is cancelled. The pulling block 4410 is pulled forward to move. When the pulling block 4410 moves, it drives the fixed block 442 to move, so that the fixed block 442 moves along the fixed rod 441. When the fixed block 442 moves, the fixation of the detection line of the phase sequence meter 43 is cancelled, and the detection line of the phase sequence meter 43 can be removed, and the phase sequence meter 43 can be taken out from the fixing seat 42, waiting for the next detection.
