Temperature control system of drilling equipment

The invention relates to the technical field of drilling equipment, in particular to a temperature control system for drilling equipment. The well temperature instrument comprises a well temperature instrument body, a first limiting groove, a second limiting groove, a protection plate, a brush, an adjusting base, a spring, a supporting column, a connecting plate and a bolt. The well temperature instrument has the beneficial effects that the protection plate is arranged in front of the control panel of the well temperature instrument body and effectively protects the panel, so that the situation that the panel is damaged due to collision of external objects is avoided, and a brush effectively cleans dust adsorbed on the surface of the panel in the pulling process of the protection plate; the adjusting seat moves downwards through elastic jacking of the spring when the bolt is loosened, so that the use height of the well temperature instrument body is adjusted, the bottom of the well temperature instrument body
