A kind of rotatable street lamp
Technical field
The invention belongs to street lamp fields, and in particular to a kind of rotatable street lamp.
Background technology
Existing street lamp is typically all to be fixedly mounted on lamppost, can only illuminate a region in this way, most of street lamp is big
Part-time does not play a role, so street lamp is generally all bigger in the few local installation interval of people, installs night in this way
Between subregion it is darker always, traveler be difficult find this part road conditions.
Invention content
For the above-mentioned prior art, the purpose of the present invention is to propose to a kind of rotatable street lamp, night illumination can be expanded
Range.
The technical proposal of the invention is realized in this way:A kind of rotatable street lamp, including lamp cap, lamppost and rotation dress
It puts, tumbler, which includes power plant, drive mechanism and positioning lampshade, power plant, can provide lamp cap rotational power, positioning lamp
Cover can limit interior structural location and prevent internal structure from exposing to the sun and rain, drive mechanism include crank, connecting rod, rocking bar, turbine and
Worm screw, lamp cap are fixed on rocking bar one end and allow lamp cap that rocking bar is followed to swing, and rocking bar centre position is equipped with turning for horizontal direction
Axis cause rocking bar can the rotation of relative positioning lampshade, the rocking bar other end is hinged with connecting rod one end, and the connecting rod other end is hinged with crank, song
Handle is fixed together with turbine and is moved around same shaft rotation, and worm screw can realize deceleration transmission, power plant and snail with turbine match
Bar connection can drive worm screw to rotate.
The advantageous effect designed in this way is that night power plant is started to work so that rocking bar starts to swing and drive lamp cap
Backswing, which is moved, considerably increases illumination region, it is possible to reduce street lamp installation number reaches energy-efficient effect.
Further, power plant is motor, stabilization easy to control in this way.
Further, solar panel being equipped with above positioning lampshade, solar panel can provide the electric energy of rotation and illumination, this
The environmental protection of sample relative energy-saving.

Specific embodiment
As needed, the specific embodiment of the present invention is disclosed herein, it will be appreciated that the disclosed embodiments are
The demonstration present invention, the present invention can the implementations of different and alternative form.Attached drawing is not necessarily drawn to scale, and certain features can be overstated
It is big or reduce details to show particular elements.Therefore, specific structure and function details disclosed herein are understood not to
It is in a limiting sense, but it is of the invention those skilled in the art to be instructed differently to use only as representative basis.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained without creative efforts
Example is applied, shall fall within the protection scope of the present invention.
As shown in Fig. 1 Fig. 2, a kind of rotatable street lamp includes including lamp cap 1, lamppost 3 and tumbler, tumbler
Power plant 11, drive mechanism and positioning lampshade 2, power plant 11 can provide lamp cap 1 rotational power, and positioning lampshade 2 can limit
Interior structural location simultaneously prevents internal structure from exposing to the sun and rain, and drive mechanism includes crank 8, connecting rod 7, rocking bar 4, turbine 9 and worm screw
10, lamp cap 1 is fixed on 4 one end of rocking bar and allows lamp cap 1 that rocking bar 4 is followed to swing, and 4 centre position of rocking bar is equipped with horizontal direction
Shaft 5 so that rocking bar 4 can relative positioning lampshade 2 rotate, 4 other end of rocking bar is hinged with 7 one end of connecting rod, 7 other end of connecting rod with song
Handle 8 is hinged, and crank 8 is fixed together with turbine 9 and is moved around same shaft rotation, and worm screw 10 matches with turbine 9 can realize that deceleration passes
Dynamic, power plant 11 is connect with worm screw 10 can drive worm screw 10 to rotate.
As shown in Fig. 1 Fig. 2, power plant 11 is motor.
As shown in Fig. 1 Fig. 2, positioning lampshade 2 top is equipped with solar panel 6, solar panel 6 can provide rotation and
The electric energy of illumination.
