Abstract
The utility model provides an oil field well construction low-voltage anti-explosion illuminating equipment, which is composed of an anti-explosion control cabinet, an anti-explosion light fixture, a light fixture supporting bracket, and a conducting wire. The equipment is operated with AC 220V or 380V power supply and outputs 36V safe extra-low voltage. A triangle flexing bracket is adopted for the light fixture bracket. The anti-explosion light fixture can rotate by 300 degrees vertically and 360 degrees horizontally on the light fixture bracket. The utility model is convenient to be used, overcoming the shortcomings of present light fixtures not meeting the practical requirements of the construction site and easy occurrences of electric shocks, fires and explosions. The utility model can fully guarantee the safety of staffs and equipment, and meet the lighting requirements of the construction site.
Description
Technical field the utility model relates to the oil field well workover low-voltage explosion-proof lighting apparatus that a kind of oil well repairing operation is used.
Background technology is present, oil underground work, light maintenance operation, the logging operation car, field maintenance, the engineering lighting apparatus that territory lighting uses such as recover has two kinds: a kind of is 220 volts the common searchlight that generally uses, owing to the particularity of oil well repairing operation, environment for use is open-air and roving place, therefore, lead and light fixture are easy to damage, and cause leaky often to occur, add that light fixture need move around, the workman is easy to take place electric shock accidents.Another kind is with 220 volts of not explosion-proof control cabinet inputs, export 24 volts, use 24 volts of autobulbs (not explosion-proof lamp), because the construction site is the oil gas well, crude oil and natural gas often appear at the construction field (site), use not explosion-proof control cabinet and explosion-proof lamp not, if produce electric spark in the job site of natural gas is arranged, consequence is hardly imaginable.24 volts of automobile lamps aim at Pavement Design, and light beam is an ellipse, and what illuminate is (plane) ground, are three-dimensional working spaces and oil well repairing operation requires to illuminate, thereby 24 volts automobile lamps can not satisfy the job site needs that throw light on.
The summary of the invention the purpose of this utility model is to provide a kind of job site illumination needs that satisfy, and has dangerous oil field well workovers such as preventing person electric shock and well shooting, is fit to the special low-voltage explosion-proof lighting apparatus of the adverse circumstances at field construction scene, oil field.
For achieving the above object, oil field well workover low-voltage explosion-proof lighting apparatus of the present utility model is made up of explosion-proof control cabinet, explosion-proof lamp, lamp bracket, lead four parts.Explosion-proof control cabinet is made up of flame-proof switch, explosion-proof casing, change-over switch, transformer.Transformer and change-over switch are contained in the explosion-proof casing, and the specified input voltage of transformer is for exchanging 220 volts and 380 volts, and rated output voltage is 36 volts.Change-over switch is closed, high light, normal three positions.Lamp bracket adopts the triangle expansion bracket, explosion-proof lamp 300 degree up and down on support, level 360 degree rotations.Lead adopts cabtyre flexible wire.
After adopting said structure, transformer and change-over switch are positioned at the explosion-proof casing of sealing, have avoided and job site crude oil and contacting natural gas, thereby have eliminated the danger that causes blasts on fire such as natural gas because of the circuit spark.What transformer was exported is 36 volts of lower security low-voltages, and the workman does not have the danger of electric shock.Explosion-proof lamp can rotate, and is easy to use, solved light fixture irradiation position problem, therefore satisfies job site illumination needs, prevents dangerous generations such as person electric shock, well shooting.
Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the circuit diagram of the utility model oil field well workover low-voltage explosion-proof lighting apparatus.
Fig. 2 is the schematic diagram of the utility model oil field well workover low-voltage explosion-proof lighting apparatus.
The specific embodiment as shown in Figure 1, alternating current enters the change-over switch 2 that is positioned at explosion-proof casing 7 through flame-proof switch 1, change-over switch 2 has three outgoing positions, be connected on the diverse location of transformer 3 inputs, can when normal the use, export different voltages, be used to regulate the brightness of lighting, to adapt to on-the-spot needs.Transformer 3 is positioned at explosion-proof casing 7, when change-over switch 2 in the normal position 36 volts of voltages of time output, and the accessory power outlet on explosion-proof casing 7 is connected with explosion-proof lamp 4 with lead 5.Explosion-proof lamp 4 is generally three covers, so that illuminate the job site simultaneously from a plurality of directions.Explosion-proof lamp 4 adopts the light projector shell of anti-explosion lamp, and light source adopts 36 volts high light efficiency based on halogen bulb of customization.Lamp bracket 6 adopts the triangle expansion brackets, explosion-proof lamp 4 300 degree up and down on lamp bracket 6, and level 360 degree rotations can solve light fixture irradiation position problem.Lead 5 adopts cabtyre flexible wires, and is not only safe but also be convenient to arrange.
Claims (2)
