Description

Technical Field

[0001] The utility model relates to the technical field of rain shields for thermometers, and more specifically, to a rain shield for a transformer thermometer. Background Technique

[0002] A transformer is a basic equipment for power transmission and distribution, which is widely used in industries, agriculture, transportation, urban communities and other fields. The principle of a transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, secondary coil and iron core. For transformers installed outdoors, many users, especially users of Southern Power Grid and State Grid, require installing protective covers outside the oil surface thermometer and winding thermometer for rain protection and sun protection. Therefore, it is necessary to install a rain shield on the transformer oil tank to shield the oil surface thermometer and winding thermometer.

[0003] Chinese Patent CN212513358U discloses a rain shield for a thermometer of a transformer and a transformer. The rain shield part includes a cover body, a thermometer installation bottom plate and an installation bracket. Among them, three thermometers can be installed on the installation bracket.

[0004] However, although the installation bracket in the rain shield for the thermometer of the transformer disclosed in the above patent can fix multiple thermometers, due to the different sizes of the thermometers, multiple threaded holes for fixing need to be opened to ensure that the position of the thermometer can be adjusted. However, once it is fixed and the position needs to be adjusted, the thermometer still needs to be disassembled and replaced, which affects the construction and installation progress.

[0005] Based on the above problems, the proposed thermometer rain shield has fixed points on the internal installation bracket that can be adjusted up and down, which is convenient for adjusting the position of the thermometer at any time. The adjustment work can be completed without disassembling the thermometer, improving the installation efficiency. Summary of the Utility Model

[0006] The utility model provides a rain shield for a transformer thermometer to overcome the problems raised in the above background technique.

[0007] To solve the above technical problems, the technical solution of the utility model is as follows:

[0008] A rain shield for a transformer thermometer includes a housing, a back fixing plate for installing the housing on the transformer, an observation window, and a thermometer installation bracket. The bottom of the housing is designed to be open; the installation bracket is fixed inside the housing. Among them,

[0009] The mounting bracket includes at least one longitudinal guide rail, at least one transverse guide rail slidably mounted on the longitudinal guide rail, and a second bolt for fixing the transverse guide rail to the longitudinal guide rail. A chute is provided on the outer end face of the transverse guide rail along its length direction. A plurality of sliders are arranged inside the chute, and a thermometer fixing member is arranged on the sliders.

[0010] Preferably, the front end of the outer shell is open, and observation window mounting plates are arranged on both sides of the front end of the outer shell; the observation window is detachably mounted at the front end of the outer shell through a fixing member of the observation window.

[0011] More preferably, the fixing member of the observation window includes a first bolt and a nut. The first bolt is arranged on the observation window mounting plates on both sides and faces the observation window. Mounting holes are arranged on both sides of the observation window and are in alignment with the positions of the first bolts.

[0012] Preferably, there are two longitudinal guide rails, and the two longitudinal guide rails are symmetrically arranged on the left and right inside the outer shell. Grooves for sliding cooperation with the two longitudinal guide rails are arranged at both ends of the transverse guide rail.

[0013] More preferably, the cross-sections of the slider and the chute are both "T"-shaped. The two ends of the chute are open, and the slider and the transverse guide rail form a detachable structure.

[0014] More preferably, the thermometer fixing member is arranged on the end face of the slider facing the thermometer, and the fixing member is an internal thread hole or a third bolt.

[0015] More preferably, a rain shield extending forward is arranged at the top of the front end of the outer shell.

The mounting holes on the thermometer back plate can be mounted on the third bolt and then fixed with nuts to install and fix the thermometer. In the prior art, the mounting bracket inside the rain shield has multiple mounting holes. If the thermometer is fixed in one position and then needs to be adjusted, it needs to be disassembled for adjustment, which affects the installation progress.

[0020] 2) A detachable observation window is provided. Compared with some prior arts where the observation window is embedded in the side wall, by setting a detachable observation window, it is convenient to replace at any time, and the observation window made of acrylic sheet is not easily damaged.
