Description
Technical field
The utility model relates to street lamp field, particularly relates to a kind of street lamp.
Background technology
Street lamp uses mainly as road lighting, in prior art, the lamp stand of street lamp is more the steel-tube construction adopting hollow, installing port is provided with in the lamp stand bottom of street lamp, controller etc. is put into lamp stand inside by this installing port by workman, cover plate is used to be closed by this installing port afterwards, in use, mainly there is following problem: due to the impact of the environment such as wind and rain, the easy from then on installing port place of rainwater enters lamp stand inside, and after rainwater enters lamp stand, the internal environment of lamp stand will be changed, it is made to become moist environment from drying, if too moist in lamp stand, by to the controller in lamp stand, and circuit causes damage, severe patient also will cause the danger such as short circuit, secondly moist environment also will cause corrosion to lamp stand inner tubal wall, reduce stability and the service life of lamp stand, and the problems referred to above are particularly evident during the broiling summer, therefore, must be solved the problems referred to above.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provides a kind of street lamp, to solve humid environment corrosion lamp stand in current lamp stand, circuit to be existed to the technical problem of potential safety hazard.
In order to realize the purpose of this utility model, the technical scheme that the utility model adopts is:
Design a kind of street lamp, comprise lamp stand, the installing port be opened on lamp stand; The upper end of described lamp stand is provided with ventilation duct, and described ventilation duct is inverted u-shaped, and the air entry of its ventilation duct is communicated with the internal cavities of lamp stand, and its exhaust outlet is arranged downward; The bottom tube wall of described lamp stand offers inlet channel; Described inlet channel is obliquely installed, and is positioned at the vertical height of the air inlet of the inlet channel on lamp stand outer tube wall, lower than the vertical height of the gas outlet of the inlet channel be positioned on lamp stand inner tubal wall; The outer tube wall of the lamp stand above described air inlet is also provided with weather shield; Also filter screen is provided with at described air inlet and exit.
Described inlet channel is at least two, and is from top to bottom uniformly distributed, and the multiple inlet channels be positioned on same vertical line form vertical inlet channel group.
The vertical inlet channel group be arranged on lamp stand is at least two groups, and symmetrical about the axis of lamp stand.
Also filter screen is provided with in the exhaust ports of described ventilation duct.
The beneficial effects of the utility model are:
1. the utility model arranges inlet channel by the bottom at lamp stand, can be blown into wind by this inlet channel to lamp stand inside, for the moisture issues in lamp stand, is solved by the wind be blown into; And the ventilation duct designed by the utility model, combine at the inlet channel with below, the principle forming chimney exhaust is more conducive to bottom air intake, top air draft, as guaranteeing that lamp stand inside is unlikely to moist, extend the service life of lamp stand, also for circuit improves more applicable environment.
2. the filter screen designed by the utility model, can prevent the foreign material such as leaf from entering in lamp stand, also avoids foreign material to block air intake passage.
3. the weather shield of the design, at the weather of rain, the catadromous rainwater on lamp stand top can by its drainage, be avoided entering in inlet channel by weather shield thus.

The lamp stand section primary structure schematic diagram of Fig. 2 designed by the utility model;
Fig. 3 is A portion structure for amplifying schematic diagram in Fig. 2;
In figure: 1. lamp stand; 2. installing port; 3. ventilation duct; 4,8. filter screen; 5. wind; 6. weather shield; 7. inlet channel.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment 1: a kind of street lamp, see Fig. 1, Fig. 2, Fig. 3; It comprises lamp stand 1, the installing port 2 be opened on lamp stand 1; The upper end of described lamp stand 1 is provided with ventilation duct 3, and described ventilation duct 3 is in inverted u-shaped, and the air entry of its ventilation duct 3 is communicated with the internal cavities of lamp stand 1, and its exhaust outlet is arranged downward; The bottom tube wall of described lamp stand 1 offers inlet channel 7; Described inlet channel 7 is obliquely installed, and is positioned at the vertical height of the air inlet of the inlet channel 7 on lamp stand 1 outer tube wall, lower than the vertical height of the gas outlet of the inlet channel 7 be positioned on lamp stand 1 inner tubal wall; The outer tube wall of the lamp stand 1 above described air inlet is also provided with weather shield 6; Filter screen 4,8 is also provided with at described air inlet and exit.As shown in the figure, described inlet channel 7 is at least two, and is from top to bottom uniformly distributed, and the multiple inlet channels 7 be positioned on same vertical line form vertical inlet channel group.The vertical inlet channel group be arranged on lamp stand 1 is at least two groups, and symmetrical about the axis of lamp stand 1; Wind can be blown into lamp stand inside by this inlet channel, for the moisture issues in lamp stand, be solved by the wind be blown into; Also filter screen is provided with in the exhaust ports of described ventilation duct 3; By the ventilation duct of the present embodiment, combine at the inlet channel with below, the principle forming chimney exhaust is more conducive to bottom air intake, top air draft, as guaranteeing that lamp stand inside is unlikely to moist, extend the service life of lamp stand, also for circuit improves more applicable environment.And above-mentioned filter screen can prevent the foreign material such as leaf from entering in lamp stand, foreign material are also avoided to block air intake passage.
Although; what embodiment of the present utility model was announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present utility model, and make different amplifications and change; but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
