Marine explosion-proof lamp

Abstract

The invention relates to a marine explosion-proof lamp, which comprises a main support of the lamp and a lamp body, wherein the main support of the lamp is arranged on a steel structure main body, and the lamp body is arranged on the main support of the lamp; the lamp comprises an aluminum housing, the aluminum housing is provided with a sacrificial anode module which is electrically connected with the aluminum housing of the lamp. The sacrificial anode module in the marine explosion-proof lamp provided by the invention can be detachably arranged on the aluminum housing of the lamp, so that the marine explosion-proof lamp has an independent protection function; when the marine explosion-proof lamp reaches the service life period, the relative sacrificial anode module is changed, so that the marine explosion-proof lamp is convenient to maintain, the service life period of the lamp is improved, the corrosion resistance of the lamp is remarkably improved, the service life of the lamp is prolonged, and the economic loss of a customer caused by the lamp damage is avoided.

Description

technical field [0001] The invention relates to the field of lamp lighting, more specifically, to a marine explosion-proof lamp. Background technique [0002] In recent years, marine development has been widely valued. Various marine transportation vehicles and various offshore production facilities are made of Q450 structural steel. A large number of electrical equipment and lighting facilities are installed on these metal structures. These facilities are located in the marine atmosphere area of ​​wind, fog, rain, and sun all year round, and are in the splash area affected by tides and waves or seawater immersion for many years. Brush and fully immerse the area with sea mud. In such a harsh marine environment, the corrosion rate of metals is much greater than that of land. At the same time, with the development of modern lighting, the industrial environment has higher and higher requirements for the stability and reliability of lamps and their auxiliary components. One of...

Problems solved by technology

[0003] At present, there are mainly two types of surface protection treatments for various explosion-proof marine environment lamps developed by domestic companies in the same industry. One is to use electrostatic spraying epoxy polyester plastic powder coating process, and the other is to use electrophoretic spraying epoxy polyurethane paint. However, both schemes are passive protection, which can only protect against oxygen absorption and hydrogen evolution corrosion, and it is difficult to resist salt in the offshore atmospheric area and galvanic corrosion between metals, and they are resistant to CL - The penetration ability of ions is extremely poor, and the effective period of weather resistance may be shortened due to the insufficient thickness of the coating

The aluminum alloy sacrificial anodes installed on drilling platforms and other facilities are suitable for cathodic protection of structures such as ships in seawater, port engineering and marine facilities, seawater cooling water systems, etc., and are generally installed underwater, far away from the protection position of lamps. It is difficult to play the role of compensating and balancing the potential difference of the steel structure near the lamp
