Description

Self-generating railway street lamp for generating electricity by using tension spring and suction force

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.

detailed description

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

Embodiment 1 Referring to Figures 1 to 4, the present invention mainly comprises a suction force swinging device, a tension spring elastic potential power generating device, a time setting device and a street light assembly. In the manual suction swinging device, the main component suction plate 11 is disposed at a position close to the train and the railway, and the suction force generated when each train passes is such that the suction plate 11 swings once toward the train, and the power thereof will be tensioned. 24 Stretches from bottom to top, gradually accumulating elastic potential energy; at the same time, it also provides operating power for the mechanism in the time setting device.

Referring to Figures 3 and 4, the suction force swinging device includes a suction plate 11 and a bracket 12 disposed at the front of the street lamp post 41, two chain bars 13 at the upper portion of the street lamp column, two sprockets 14, and a balance weight 15, a transmission 16 , a check ratchet mechanism 5 , a spline shaft 18 , a top plate 19 , a compression spring 182 and a positive conical friction wheel 181 , a second transmission 39 , two support plates 17 ;

The 12-end of the bracket 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 receives a suction force, and the two fixed components can swing toward the train about the hinge. 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 counterweight 15 passes through the chain 13, and the suction plate 11 is returned to the initial position for the next swing.

The first transmission 16 and the second transmission 39 are respectively fixed to the two sides of the street lamp column 41 through two supporting plates 17 , and the input shafts of the first transmission 16 and the second transmission 39 are respectively connected to the sprocket 14 , and the sprocket 14 is provided therein. There is a ratchet, which is similar to a ratchet-equipped sprocket in the rear wheel of the bicycle (see Fig. 12); each of the sprockets is engaged with a chain 13, and one end of each chain 13 is connected to the upper portion of the suction plate 11, The other end is connected to the counterweight 15; Referring to Figure 3, when the chain 13 drives the sprocket 14 to rotate counterclockwise, the first transmission 16 and the second transmission 39 operate with the sprocket 14; when the sprocket 14 rotates clockwise At the time, the first transmission 16 and the second transmission 39 do not operate with the sprocket 14 due to the anti-reverse function of the ratchet. As shown in Fig. 4, the input shaft of the first transmission 16 is opposite to the rotation direction of the output shaft because the tension spring 24 is provided at the front of the street lamp post 41. If the input shaft of the first transmission 16 is rotated in the same direction as the output shaft, the tension spring 24 should be provided at the rear of the street lamp post 41.

The output shaft 1 61 of the first transmission 16 is coupled to the check ratchet mechanism 5 and the spline shaft 18; the spline shaft 18 is hinged to the street lamp post 41 via the top plate 19; one end of the spline shaft 18 is connected to the active tapered friction wheel 181, spline The other end of the shaft 18 enters a spline hole (not shown) in the output shaft 1 61 of the transmission and is axially movable in the spline hole; a compression spring 182 is disposed between the active conical friction wheel 181 and the top plate 19. The compression cone spring 182 is pressed against the active cone friction wheel 181 to engage the drive sprocket 21 to transmit torque; to prevent the tension spring from freely contracting downward, a check ratchet mechanism 5 is provided (see FIGS. 4, 6, and 8). The check ratchet mechanism 5 includes a ratchet 51 provided on the output shaft 161 of the first transmission, a pawl 52 provided on the support plate 17, a pawl pin 53 and a pawl torsion spring 54; the pawl torsion spring 54 forces The pawl 52 is always engaged with the ratchet 51. When the active cone friction wheel does not transmit torque, the tension spring will contract freely, but its contracted elastic force passes through the tension chain 23, the drive sprocket 21, the active cone friction wheel 181, the spline shaft 18, and the first transmission. The output shaft 161 and the ratchet 51 are transmitted to the pawl 52, and the pawl 52 prevents the ratchet 51 from rotating, thereby preventing the tension spring from freely contracting.

The output shaft of the second transmission 39 is connected to the first conical friction wheel 31 in the time setting device; the suction force swinging device mainly supplies power to the tension spring of the tension spring elastic energy generating device, and is also set for time The spring in the device is twisted to provide power;

The driving sprocket 25 is meshed; the driving sprocket 21 and the driven sprocket 25 are the same as the sprocket 14, and each of them is provided with a ratchet; when the driving sprocket 21 stretches the tension spring 24 upward by the stretching chain 23, the driven chain The wheel 25 is idling; when the tension spring 24 is contracted downward, the drive sprocket 21 is idling, and the elastic force of the tension spring 24 drives the driven sprocket 25 to rotate by the tension chain 23, and then the speed is increased by the third transmission 27. The governor 28 stabilizes the rotational speed and drives the direct current generator 29 to rotate to generate electricity. The reason for using the governor here is that the elastic force of the tension spring is gradually weakened, which causes the speed of driving the DC generator to be fast and slow first, which is not conducive to normal power generation. The speed of the third transmission can be stabilized at a certain speed by the governor. The governor 28 can be a known mechanical centrifugal governor. The drive sprocket 21 is hinged to the street lamp post 41 via the support plate 22, and the driven sprocket 25 is hinged to the lower portion of the street lamp post 41 via the support 26; the third transmission 27 is fixed to the support 26; the driven sprocket 25 and the third transmission 27. The governor 28 and the direct current generator 29 are sequentially connected; the tapered hole 211 in the drive sprocket 21 is intermittently frictionally coupled with the active tapered friction wheel 181 on the spline shaft 18, specifically, compression. When the spring 182 pushes the active cone friction wheel 181 into the tapered hole 211, the two perform friction transmission, and when the jack 39 in the time setting device pushes the active cone friction wheel 181 away from the tapered hole 211, neither Re-contact transmission power; DC generator 28 and street light illuminating member 4 are electrically connected by wires Description The book spring elastic potential power generating device supplies power to the light-emitting member 4 of the street lamp;

One end of the jack 39 is in contact with the cam 38, and the other end is in contact with the active tapered friction wheel 181 through the drive sprocket 21;

The hour hand shaft 371 is coaxially connected to the cam 38; the clock 37 can be rotated by a known hour hand shaft into a 24-hour clock structure. Thus, the cam 38 is also rotated for 24 hours. The arc length of the side of the cam 38 is the time during which the street light is turned off during the day, and the arc length of the convex side of the cam 38 is the time when the night street light is turned on. The first conical friction wheel 31 and the first conical friction wheel 32 transmit torque in a frictional manner to prevent the clockwork and associated mechanisms from being damaged by overload. The time setting device timing control activates the spring-loaded elastic potential power generating device to generate electricity.

The street lamp assembly includes 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 electrically connected to the DC generator 28 through a wire. The street lamp illuminating member 4 is elastically energized by the tension spring at night. The electric energy generated by the power generating device emits illumination;

In summary, the method of using the above device: During the daytime, when the train passes the street light, the airflow 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 is provided. And the bracket 12 swings toward the train; the upper part of the suction plate 11 pulls the two chains 13 to drive the two sprockets 14, the first transmission 16 and the second transmission 39 to operate;

The output shaft of the second transmission 39 passes through the friction transmission of the first friction wheel 31 and the second friction wheel 32 to drive the meshing transmission of the first piece gear 33 and the second piece gear 34, so that the spring twisting shaft 35 twists the clock 37 a spring that energizes the rotation of the hour hand shaft 371 and the cam 38 of the clock 37;

When the train passes, the suction force disappears, and the gravity of the balance weight 15 pulls the chain 13 to make the suction plate The book returns to the original state; multiple trains pass, the sprocket 14 is rotated multiple times, the tension spring 24 is continuously stretched upward to accumulate elastic potential energy, and at the same time, the spring of the clock 37 is continuously tightened;

When the tension spring 24 is blocked upward by the upper positioning rod 231, the active cone friction wheel 181 is slipped and rotated by the overload to provide a safety protection function;

On the other hand, when the torque of the twisted spring exceeds the transmission torque of the first tapered friction wheel 31 and the second tapered friction wheel 32, the first tapered friction wheel 31 slips and rotates, thereby providing a safety protection function;
