Description

Railway self-generating street lamp with suction power as power generation technology

The invention belongs to a lighting device, in particular to a street lamp that uses natural energy to generate electricity.

Background technique

In order to save energy and protect the environment, street lamps that use solar energy and wind energy to provide electricity have emerged. These two natural energy street lights are especially suitable for lighting along railways. Because the illumination of long-distance railway lines consumes considerable power resources. However, both sources of energy are unstable. For example, on a continuous rainy day, the power supply of solar street lights becomes a problem. Windless street lights will stop working in continuous windless or breezy weather. Studying a streetlight along a railway powered by stable natural energy has become an important issue.

Another noteworthy phenomenon is that: On both sides of the high-speed railway, guardrails are usually built to prevent passers-by from blindly approaching the track and being injured by the high-speed train that is instantaneous. Because of the high-speed airflow generated by the rapid transit of high-speed trains, there is a suction effect on people or objects on both sides of the railway. If people or objects are too close to the high-speed train, they will be sucked into the train by this suction force. This phenomenon can be explained by Bernoulli's principle. The faster the flow rate, the lower the pressure, so people or objects close to the train will be pushed from the high pressure zone to the low pressure zone.

Summary of the invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a street lamp having a stable natural energy power supply device in view of the deficiencies of the above-mentioned natural energy power generation street lamp.

The amplitude of the swing is controlled by an upper limit lever 91 and a lower limit lever 92 provided on the street lamp post (see Figs. 3 and 9). The magnitude of the suction force is substantially proportional to the area of the suction plate 11, that is, the larger the suction plate 11, the greater the suction force obtained. When the train After the passage, the suction force disappears, and the weight of the balance weight 15 passes through the chain 13, and the suction plate 11 is returned to the initial position for the next swing. The two transmissions 16 are respectively fixed to the two sides of the street lamp column 41 through two supporting plates 17, and the input end of the transmission 16 is connected with the sprocket 14, and each of the sprocket wheels 14 is engaged with a chain 13 for each chain 13 One end is connected to the upper portion of the suction plate 11, and the other end is connected to the balance weight 15; the sprocket 14 is provided with a ratchet (not shown); the sprocket is similar to the sprocket containing the ratchet in the rear wheel of the bicycle. When the chain 13 drives the sprocket 14 to rotate counterclockwise, the input shaft of the transmission 16 is also driven to rotate in the same direction; when the sprocket 14 rotates clockwise, the input shaft of the transmission 16 does not follow the chain due to the anti-reverse function of the ratchet. The wheel 14 rotates. The output of the transmission 16 is coupled to an internal ratchet 18, and the internal ratchet 18 is coupled to the flywheel 21, see FIG. 8; the transmission 16 functions to further increase the rotational speed of the sprocket 14 to provide a higher flywheel 21 Angular velocity and mechanical kinetic energy. The function of the internal ratchet 18 is that after the flywheel 21 is pushed, the flywheel 21 continues to rotate by its greater rotational inertia, and the transmission 16 no longer follows the rotation to avoid consuming the mechanical kinetic energy of the flywheel 21.

After the train passes the street light, the suction force disappears, and the gravity of the balance weight 15 pulls the chain 13 to return the suction plate 11 to the original state, so as to be attracted by the suction force for the next time; the mechanical kinetic energy stored by the flywheel 21 gradually Reduced, the rotational speed of the flywheel 21 is gradually reduced and no longer effectively generates electricity;

When the next train passes, the above device generates power again, and the electric energy is stored in the battery 3; thus, the battery 3 gradually accumulates electric energy;

When the photosensitive sensor in the photosensitive detecting unit 57 detects that the ambient brightness is insufficient, the starting relay 56 turns on the electrical connection between the battery 3 and the street light emitting member 4 to supply light for the street light emitting member 4; when the photosensitive detecting unit 57 is photosensitive When the sensor detects that the ambient brightness is sufficient, the start relay 56 disconnects the electrical connection between the battery 3 and the street light illuminator 4, and the battery 3 stops supplying power to the street light illuminator 4, and the street light illuminator 4 is turned off.
