Description

Self-generating railway street lamp

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-driven swinging device and a flywheel power generating device. When the high-speed train passes, the swinging device is pumped by the suction force, and the swinging force causes the flywheel power generating device to store energy.

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, the transmission, the internal ratchet, the flywheel and the rotor of the generator together. The flywheel stores the mechanical kinetic energy and uses its rotational inertia to drive the generator to generate electricity.

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 adds a swinging power-powered swinging device to the street lamps on both sides of the railway. When the high-speed train passes, the swinging device is pumped by the swinging force and swings. The power causes a flywheel power generator to store energy and generate electricity at the same time. The generated electricity is stored in a flywheel battery. At night, the control circuit sends a signal, and the flywheel battery supplies power to the street light illuminator. 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 pieces The support plate 17 and the two internal ratchets 18 are provided. 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 (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 passes, the suction force disappears, and the weight of the balance weight 15 passes through the chain 13, returning the suction plate 11 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 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 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.

The flywheel power generating device mainly comprises two flywheels 21 and a generator 22 and its supporting plate 23; the two ends of the rotor 221 of the generator located in the street lamp column 41 are respectively connected with a flywheel 21; the outer casing 222 containing the generator stator passes The support plate 23 is fixed inside the street lamp post 41; the generator 22 relies on the stored mechanical kinetic energy of the flywheel 21 to continuously generate electricity for a period of time. The generator 22 supplies power to the flywheel battery unit; the flywheel power generation device is similar to a flywheel battery, except that the flywheel battery is charged and stored, and the outside is a vacuum box, and the power generation lasts for a long time. The flywheel power generating device is mechanically driven to store energy and cannot be operated in a vacuum box. During operation, the duration of power generation is short due to wind consumption, friction, and the like.

A flywheel battery unit comprising a flywheel battery 3 (see FIG. 10), a control circuit 5 (not shown); the flywheel battery unit provides power to the street light illuminator 4; a typical flywheel battery 3 is known as shown in FIG. , the flywheel 311 of the flywheel battery, the bearing 312, the motor/generator 313 of the flywheel battery, and the true The empty chamber 314 is composed of four main components. Both the motor of the flywheel battery and the flywheel of the flywheel battery are suspended by the magnetic shaft 7 to reduce mechanical friction, and the flywheel of the flywheel battery and the motor of the flywheel battery are placed in a vacuum container to reduce air friction. The input and output net efficiency of such a flywheel battery can reach 95%. The left converter 55 inputs electric energy from the outside, drives the motor of the flywheel battery to rotate, the motor of the flywheel battery drives the flywheel of the flywheel battery to rotate, and the flywheel of the flywheel battery stores mechanical kinetic energy. When the external load requires energy, the flywheel of the flywheel battery drives the generator of the flywheel battery to rotate, converts the mechanical kinetic energy into electrical energy, and then becomes the various frequency and voltage levels of electric energy required by the load through the power electronic converter 55 to meet different Demand. The power electronic converter 55 is typically a bidirectional inverter composed of a MOSFETT and an IGBT. The control circuit 5 is shown in FIG. 11 and includes a single chip microcomputer 51 and a button battery power source 52, a rectifier circuit 53, a voltage stabilizing circuit 54, a power electronic converter 55, a relay 56, and a photosensitive detecting unit 57; The generator 22 in the flywheel power generation device is connected to the voltage stabilizing circuit 54. The voltage stabilizing circuit 54, the button battery power source 52, and the light detecting unit 57 are respectively connected to the single chip microcomputer 51, and the single chip microcomputer 51 is also connected to the relay 56 and the power electronic converter 55, respectively. The power electronic converter 55 is connected to the flywheel battery 3; the electric power generated by the generator 22 in the flywheel power generating device is rectified by the rectifying circuit 53, and then regulated by the voltage stabilizing circuit 54, controlled by the single chip microcomputer 51, and passed through the power electronic The inverter 55 drives the motor 313 of the flywheel battery to rotate, the motor 313 of the flywheel battery drives the flywheel 311 of the flywheel battery to rotate, and the flywheel 311 of the flywheel battery stores the mechanical kinetic energy; when the single chip microcomputer 51 obtains the light-on signal from the photosensitive sensor in the photosensitive detecting unit 57 , the single-chip microcomputer 51 controls the power electronic converter 55 and the flywheel battery to generate power, and the single-chip microcomputer also controls the conduction relay. The electric power generated by the flywheel battery 3 is supplied to the street lamp illuminator 4 for illumination via the power sub-converter 55, the single-chip microcomputer 51 and the relay 56. When the single chip microcomputer 51 obtains the light-off signal from the photosensitive sensor in the photosensitive detecting unit 57, the single chip microcomputer 51 controls the flywheel battery 3 to stop generating electricity, and also closes the relay 56, and the street light emitting member 4 is turned off. If the light detecting unit is replaced by a time setting unit, automatic opening and closing of the street light can also be achieved. Control circuits such as a photosensitive detecting unit or a time setting unit are well known circuits. The flywheel battery 3 and the control circuit 5 described above are well known to those skilled in the art and will not be described in detail.

The inner ratchet 18, the flywheel 21 and the rotor 221 of the generator rotate together. The flywheel 21 stores mechanical kinetic energy and uses its rotational inertia to drive the generator 22 to generate electricity.

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 converted into mechanical kinetic energy and stored in the flywheel battery 3; thus, the mechanical kinetic energy is gradually accumulated in the flywheel battery 3; the photosensitive sensor device in the control circuit 5 is detected. When the ambient brightness is insufficient, the flywheel battery 3 is activated by the control circuit 5 to convert the mechanical kinetic energy into electrical energy to supply illumination to the street light illuminator 4; when the photosensitive sensor device in the control circuit 5 detects that the ambient brightness is sufficient, the flywheel is turned off by the control circuit 5. The power generation of the battery 3, the street light illuminating member 4 is extinguished; the flywheel battery 3 continues to store mechanical kinetic energy;
