Spray distance adjustable mist spray module and application of spray distance adjustable mist spray module on insulator hydrophobicity detection

Abstract

The invention provides a spray distance adjustable mist spray module and an application of the spray distance adjustable mist spray module on insulator hydrophobicity detection and belongs to the field of mist spray equipment. The spray distance adjustable mist spray module comprises a spray angle adjustable DC spray gun, a spray angle adjustment actuator and a constant-pressure flow adjustment pumping assembly. A water outlet of the constant-pressure flow adjustment pumping assembly communicates with a water inlet pipeline of the spray angle adjustable DC spray gun. The spray angle adjustmentactuator is used for adjusting the spray angle of the spray angle adjustable DC spray gun. The spray angle of the spray angle adjustable DC spray gun and the output flow of the constant-pressure flowadjustment pumping assembly are adjusted according to the spray distance. The spray distance adjustable mist spray module can set the cross sectional area of mist flow at a spray target surface and maintain the consistency of the atomizing fineness and atomizing density of the mist flow at the spray target surface.

Description

technical field [0001] The invention relates to the technical field of spray equipment, in particular to a spray module with adjustable spray distance and its application in the detection of the hydrophobicity of insulators. Background technique [0002] Appendix A of DL / T864-2004 "Guidelines for the Use of Composite Insulators for AC Overhead Lines with Nominal Voltages Higher than 1000V" stipulates the measurement method and judgment criteria for the hydrophobicity of insulators, and records a water spraying method to detect hydrophobicity by the water spraying classification method. water fixtures. [0003] In general, evaluating the hydrophobic effect of in-service insulators can guide the maintenance of in-service insulators whose hydrophobicity does not meet the design requirements. For example, the patent document CN205958027U discloses an on-line detection device for hydrophobicity of insulators based on UAV technology, and specifically discloses that it includes an...
