Description

Street lamp for generating electricity using flywheel and suction effect

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 disadvantage of existing solar and wind energy street lamps is the need to configure a chemical battery, which is regularly maintained and has a limited service life. The waste battery also pollutes the environment, and this state needs to be improved.

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, which does not require the use of a chemical battery, in view of the deficiencies of the above-mentioned natural energy power generation street lamp. The natural energy source is generated by the suction force generated by the high-speed airflow during train movement; this natural energy is stable because the number of trains that run daily is quite stable.

The main idea of the invention is: a street lamp along both sides of the railway is provided with a swinging power-powered swinging device and a flywheel power generating device. When the high-speed train passes, the swinging device is pumped by the swinging force, and the swinging force causes the flywheel power generating device to be stored. The electric power can be generated at the same time, and the electric light emitted from the train is illuminated by the street lamp. The specific technical solution of the present invention is realized as follows: The street lamp includes: The swinging device comprises a suction plate and a bracket arranged at the front of the street lamp column, two chains on both sides of the upper part of the street lamp column, two sprocket wheels, balance weights, two transmissions, two support plates, and two inscribed Ratchet; one end of the bracket is fixedly connected to the suction plate, and the other end is hinged to the lower part of the lamp post; the two transmissions are respectively fixed to the two sides of the lamp post through two supporting plates, and the input end of the transmission is connected with the sprocket, and the sprocket is provided a ratchet wheel; each of the sprockets is engaged with a chain, one end of each chain is connected to the upper part of the suction plate, and the other end is connected to the balance weight; the output end of the transmission is connected with an internal ratchet;

a flywheel power generating device comprising two flywheels and a direct current generator and a support plate thereof; the two ends of the rotor of the direct current generator located in the street lamp column are respectively connected with the flywheel; the flywheel is connected with the internal ratchet in the swing device; The outer casing including the stator of the direct current generator is fixed to the inside of the street lamp column through the support plate; the direct current generator is electrically connected with a voltage stabilizing circuit, and the voltage stabilizing circuit is electrically connected with a remote street light emitting member;

a street lamp assembly, comprising a street lamp illuminating member and a street lamp column, wherein the street lamp illuminating member is disposed at an upper portion of the street lamp column, and the street lamp illuminating member is electrically connected with the voltage stabilizing circuit in the remote street lamp;

Method of using the above device: When the train passes the street lamp, the air flow between the train and the suction plate is accelerated, and the pressure is lowered, thereby generating a suction force on the suction plate, and moving the suction plate and the bracket to the train; Pulling the chain to drive the sprocket, transmission, internal ratchet, flywheel and DC generator rotor together, the flywheel stores kinetic energy and uses its rotational inertia to drive the DC generator to generate electricity, and the DC generator sends electricity through the voltage regulator circuit. After the voltage regulation, the street light illuminating part in front of the remote train is powered and illuminated; the train passes through the arranged street lights in turn, and the street light illuminating parts in front of the train sequentially illuminate; after the train passes the street light, the suction force disappears, and the weight is balanced. Gravity pulls the chain to return the suction plate to its original state, so that it can be attracted by the suction force for the next time; the kinetic energy of the flywheel storage is gradually reduced, the rotation speed of the flywheel is gradually reduced and the power generation is no longer effectively generated, and the street lamp illuminating device is extinguished;

Repeatedly, the above device relies on the suction generated by the train to generate electricity, and supplies illumination to the street light illuminating device in front of the train.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

Embodiment 1, Referring to FIG. 4 to FIG. 7, the present invention mainly provides a swinging power and a flywheel power generating device for the street lamps on both sides of the railway. When the high-speed train passes, the swinging device obtains the suction force. The swinging and swinging force causes a flywheel power generating device to store energy and generate electricity at the same time, and the generated electricity is used for illumination of the street lamp at the far end of the train (see Figure 10 for the electrical connection of the street lamp). This flywheel power generator is similar to a flywheel battery. The difference is that the flywheel battery is charged and stored. The outside is a vacuum box, and the power generation lasts for a long time. However, during the operation of the flywheel power generation device, the duration of power generation is short due to wind consumption, friction, etc. However, many railways along the line segment usually only need to be used when the train passes, and there is no other use, so the flywheel power generation device The electricity generated is sufficient for the lighting of the train.

The swinging device mainly comprises a suction plate 11 and a bracket 12 which are arranged at the front part of the street lamp column, two chain 13 on both sides of the upper part of the street lamp column, two sprocket wheels 14, a balance weight 15, two transmissions 16, two support plates 17. Two internal ratchets 18. The bracket 12 is fixedly connected to the suction plate 11 and the other end is hinged to the lower portion of the lamp post 41. When the train passes, the suction plate 11 is suctioned, and the two fixed components can be hinged around the hinge. Swing in the direction of the train. 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. 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 passes, the suction force disappears, and the weight of the balance weight 15 passes through the chain 13, and the suction plate 11 is restored to the initial position for the next time. 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 sprocket due to the anti-reverse function of the ratchet 14 turns. The output end of the transmission 16 is connected to an internal ratchet 18, and the internal ratchet 18 is connected to the flywheel 21, see Fig. 8; the function of the transmission 16 is to further increase the rotational speed of the sprocket 14 to make the flywheel 21 have a higher Angular velocity and 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 kinetic energy of the flywheel 21.

The street lamp assembly comprises a street lamp illuminating member 4 and a street lamp column 41. The street lamp illuminating member 4 is disposed at an upper portion of the street lamp column 41, and the street lamp illuminating member 4 is electrically connected with the voltage stabilizing circuit in the remote street lamp;

The flywheel power generating device mainly comprises two flywheels 21 and a DC generator 22 and its supporting plate 23; both ends of the rotor 221 of the DC generator located in the street lamp column 41 are respectively connected with a flywheel 21; The outer casing 222 of the stator is fixed to the inside of the street lamp post 41 via the support plate 23; the direct current generator 22 continues to generate electricity over a period of time by the stored kinetic energy of the flywheel 21. The DC generator 22 is electrically connected to a voltage stabilizing circuit (not shown), and the voltage stabilizing circuit is electrically connected to a remote (front or rear) street light illuminating member 4 (see Fig. 10 for electrical connection of the street lamp), so as to The invention can be used by trains in two different directions. Specifically, the electric light emitted by the street lamp 3 in FIG. 10 illuminates the illuminating member of the street lamp 5 through the cable, and the illuminating power source of the illuminating member of the street lamp 3 is powered by the street lamp 1 power generating device, and so on. In this way, the front of the train in the picture is always illuminated by street lamps. If the train is traveling in the opposite direction as shown in the figure, the street light 5 illuminates the light-emitting member of the street light 3. The distance between the streetlights that are generated and the illuminated streetlights can be based on the actual train speed and the environment in which they are used, for example, 1500 meters apart.

The stabilized and effective power supply can be given to the street light illuminating device through the voltage stabilizing circuit. Another way to obtain a stable and efficient power supply is to add a mechanical centrifugal governor between the flywheel 21 and the DC generator 22 so that the rotor of the DC generator has a stable speed. Both the voltage stabilizing circuit and the mechanical centrifugal governor can be well-known voltage regulator circuits and mechanical centrifugal speed controllers.

In summary, the method of using the above device: When the train passes the street lamp, the air flow between the train and the suction plate 11 is accelerated, and the pressure is lowered, thereby generating a suction force to the suction plate 11, so that the suction plate 11 and the bracket 12 swinging toward the train; the upper part of the suction plate 11 pulls the chain 13, thereby driving the sprocket 14, the transmission 15, the internal ratchet 18, the flywheel 21 and the direct current generator 22 to rotate, and the flywheel 21 stores kinetic energy and utilizes its rotational inertia. The DC generator 22 is driven to generate electricity, and the electricity generated by the DC generator 22 is regulated by the voltage stabilizing circuit to supply illumination to the street light illuminating part in front of the remote train; the train passes through the street lights arranged on both sides of the railway, and the street light in front of the train The illuminating member sequentially illuminates the illumination; after the train passes the street lamp, the suction force disappears, the gravity of the balance weight 15 pulls the chain 13 to return the suction plate 11 to the original state; waits for the next suction force to be oscillated; the flywheel 21 The stored kinetic energy is gradually reduced, the rotational speed of the flywheel 21 is gradually reduced and the power generation is no longer effectively generated, and the street light illuminating member 4 is extinguished;

In this way, the flywheel power generation device of the street lamp generates electricity by the suction force generated by the train, and supplies illumination to the street light illuminating device in front of the train. .

Since the related components of the present invention operate for a relatively short period of time, no control circuit can be provided between the voltage stabilizing circuit and the street light emitting device, that is, power generation and illumination are temporarily generated during the day. It is of course also possible to provide a control circuit comprising a light-sensitive detection circuit or a time setting circuit for controlling the lighting of the street light during the day. Control circuits such as photosensitive detection circuits or time setting circuits are well known control circuits and will not be described here.

The following components are the same as the swinging device: the two transmissions 16 are respectively fixed to the two sides of the street lamp column 41 through two supporting plates 17, the input end of the transmission 16 is connected to the sprocket 14, and the sprocket is provided with a ratchet; each sprocket Each of the chains 14 is engaged with a chain 13, one end of each chain 13 is connected to the upper portion of the suction plate 11, and the other end is connected to the balance weight 15; the output end of the transmission 16 is connected to an internal ratchet 18.
