Abstract

The utility model provides a back uncovered type fast heat-radiation and explosion-protection street lamp, which is used for the illumination in inflammable and explosive work places, and mainly solves the problems in the prior art that the service life is shorter due to low heat radiating efficiency of a street lamp housing and the operation is cumbersome since a transparent cover needs to be detached when connecting wires and replacing bulbs. The back uncovered type fast heat-radiation and explosion-protection street lamp is technically characterized in that a rear end cover (2) is connected with a wiring chamber (3) via a hinge (16); inner heat absorbing fins (6) are arranged on the street lamp housing (9) on the inner side; the hinge (16) is arranged on one side of the rear end cover (2) and one side of the wiring chamber (3); the rear end cover (2) and the wiring chamber (3) are fixed by bolts; and the inner heat absorbing fins (6) arranged on the inner side of the street lamp housing (9) and distributed over the entire street lamp housing (9) present the shape of inwardly raised lattices.

Description

The explosion-proof street lamp of a kind of back open type quick heat radiating

Technical field

The utility model relates to a kind of explosion-proof street lamp, the explosion-proof street lamp of especially a kind of back open type quick heat radiating.

Background technology

In the prior art, explosion-proof street lamp can be divided into the combining structure of INCREASEDSAFETY structure or INCREASEDSAFETY light fixture and explosion-proof type ballast box substantially.The INCREASEDSAFETY constructed products has only guard shield, does not isolate the function that combustible medium enters light fixture, in case power supply contact oxidation, corrosion or loosening just are easy to generate electric arc or spark, explosion accident very easily takes place; The product of flame-proof type light fixture, though solved the technical problem that combustible medium easily enters light fixture, but they all exist another common shortcoming, both: during maintenance need the high-altitude with the light fixture lower cover on all fastening bolts pull down one by one, can open maintenance operations such as translucent cover more changes the bulb, because of the light fixture lower cover is not provided with johning knot member alive, as support or the support of pulling down part from light fixture, make this simple more on the ground work only, finish difficult in the high-altitude.

The utility model content

The purpose of this utility model is: provide a kind of back open type quick heat radiating explosion-proof street lamp, it not only has bigger endotherm area, higher heat conduction efficiency, simultaneously, rear end cap is connected by hinge with wire connection cavity, and high-altitude applications such as maintenance become with equally easy on the ground.

The technical solution of the utility model is: 3 of rear end cap 2 and wire connection cavities are linked to each other by hinge 16; At the inside part of street lamp housing 9, heat absorbing sheet 6 in being provided with.Hinge 16 is located at a side of rear end cap 2 and

wire connection cavity

3, and 3 of rear end cap 2 and wire connection cavities are by bolting.Interior heat absorbing sheet 6 is located at the inboard of street lamp housing 9, and is covered with whole street lamp housing 9, and is the latticed of internal projection

Owing to adopt above technical scheme, light fixture heat radiation, cooling problem are well solved, and have prolonged its service life; Also solved the difficult problem of high-altitude maintenance.

Description of drawings

Fig. 1 is an installation diagram of the present utility model, and Fig. 2 is the upward view of Fig. 1, and Fig. 3 is the front view of street lamp housing 9, and Fig. 4 is a figure A-A face cutaway view.

The specific embodiment

At Fig. 1, among the embodiment that Fig. 3 looked, wire connection cavity 3, radio-frequency generator 1, power supply module 4, lamp holder 5, heat radiation chamber 7, reflector 8, bulb 10, fastening bolt 11, lower cover 12, translucent cover 13 parts such as grade, same as the prior art, and the Outboard Sections of street lamp housing 9 is also same as the prior art, difference is the inside part of street lamp housing 9, in order to increase its effectively surface area of heat absorption, within it on the whole spill cambered surface of side, be provided with the latticed interior heat absorbing sheet 6 of one group of projection, as Fig. 3, shown in Figure 4, the setting of heat absorbing sheet 6 in this, can make street lamp housing 9 absorb the heat that produces from bulb 10 doubles, heat conduction efficiency improves, and the temperature in the heat radiation chamber 7 is controlled in and helps bulb 10, in the radio-frequency generator extended range in 1 service life.

Rear end cap 2 is connected with hinge 16 in a side with wire connection cavity 3.The advantage of this structure is very outstanding: more change the bulb 10 or maintenance wire connection cavity 3 in parts etc., just need not to remove fastening bolt 11, lower cover 12, translucent cover 13 etc., but only need open rear end cap 2, hinge 16 is born supporting role, it is auxiliary to need not other people, and a people just can easily finish associative operation.
