After the two dustproof guard plates 1061 are closed inside the closed groove 1062, the elastic block 1066 is deformed to elastically clamp the clamping head 1069 inside the clamping hole 1068, so that the dustproof guard plate 1061 is easily closed inside the closed groove 1062 for fixed installation. The internal protection closed in the closed groove 1062 provides dust protection for the surface of the heat dissipation net 106. When not in use, the heat dissipation net 106 is protected from dust entering the inside, thereby improving the dust protection effect of the online monitoring device body 100 after online monitoring of the transformer oil chromatography of the Internet of Things. When the online monitoring device body 100 is used for monitoring and heat dissipation treatment, the torsion spring 1064 remains stationary and the deformation occurs, and the shaft 1063 rotates in place to elastically open the dust protection plate 1061, exposing the heat dissipation net 106 to the outside world for internal heat dissipation treatment.
