Description

Technical Field

[0001] The invention relates to the technical field of traffic signal lights, in particular to a movable traffic warning light based on frictional electric-electromagnetic coupling. Background Art

[0002] With the rapid development of the transportation industry, the tasks and requirements of traffic management are increasing day by day. The existing traffic warning lights on the road have gradually become difficult to adapt to the needs of modern road traffic management. Traffic warning lights are usually required to be placed in some construction or accident-prone sections, but traditional traffic warning lights are generally powered by underground power grids and are inconvenient to move.

[0003] In addition, industry insiders have also proposed some patent improvements for the power design of traffic warning lights, such as announcement number CN The Chinese utility model authorized patent No. 210200003U discloses a traffic light alternately supplied with direct current and solar energy storage. Through the cooperation of a battery placement box, a controller, a storage battery and a solar panel, the storage battery can be stored through the solar panel after being in a specified position, which is convenient for powering the traffic light. The traffic light uses solar energy to achieve energy-saving effects, but solar energy is greatly affected by geographical location and day and night, and is costly and inconvenient to maintain. For example, the Chinese invention patent application with publication number CN118375562A discloses a breeze collection and power generation device, which is based on friction nano-power generation technology. The wind cup part drives the rotating shaft part to rotate under the action of the breeze, so that the flexible blade part rotates in the shell and contacts the aluminum sheet stator on the frame. The flexible blade part and the aluminum sheet stator contact and overlap multiple times during the rotation process to achieve power generation, and the origami structure TENG is compressed and stretched during the contact process to generate electricity. However, the origami structure used in the power generation device has a large resistance, resulting in a high requirement for the starting wind speed. For traffic warning lights used on urban roads, the wind force in the environment is usually not very large, making it difficult to achieve effective power supply.

[0004] In summary, in view of the disadvantages of existing traffic warning lights, such as inconvenient power supply, poor mobility and high power generation cost, it is urgent to optimize the main structure of traffic warning lights, especially the supporting power generation components, to solve the above problems of traffic warning lights.

[0037] Combination Figure 3 , Figure 5 , Figure 7As shown, the power shaft 5 is coaxially rotatably mounted inside the housing 2, and bearing holes with a diameter of 28 mm are processed at the center of the housing top cover 8 and the housing bottom plate 14. In addition, at the edge of the housing bottom plate 14, that is, on a circle with a radius of 130 mm and the center of the housing bottom plate 14 as the center, bearing holes with a diameter of 28 mm are evenly arranged, which are the same as the number of the secondary cylinders of the housing 2, and a 16001 bearing of GB 276-94 is installed in each bearing hole. The bearing has an outer diameter of 28 mm, an inner diameter of 12 mm, and a thickness of 7 mm. The two ends of the power shaft 5 are rotatably mounted between the two bearings of the housing top cover 8 and the housing bottom plate 14. The power shaft 5 is designed in the form of a stepped shaft, which is divided into six sections from the bottom to the top: Section I is 7mm long and 12mm in diameter, and cooperates with the bearing installed in the center of the housing chassis 14; Section II is 122mm long and 14.4mm in diameter, and a 7mm through-hole is radially penetrated near the bottom of this section of the shaft, and two hanging rings are symmetrically arranged near the top of the through-hole for the installation of the engaging ball mechanism 17; Section III is 3mm long and 19mm in diameter, and plays an axial positioning role for the rotor 6; Section IV is 16mm long and 14.4mm in diameter, and a spline with a length of 7mm, a width of 3mm, and a height of 4.3mm is machined at the bottom of this section of the shaft, and the intersection line of the high and long surfaces is rounded with a fillet radius of 1mm, and it is connected to the rotor 6 as a whole through the spline to play a radial positioning role; Section V is 19mm long and 12mm in diameter, and cooperates with the bearing installed in the center of the housing top cover 8; Section VI is 15mm long and 10mm in diameter, and cooperates with the coupling 10.

[0038] The rotor 6 is in the shape of a squirrel cage as a whole, and a plurality of L-shaped frames are evenly arranged along the center of rotation. The transverse arms of the plurality of L-shaped frames are connected as a whole and a spline groove is provided in the center to be spline-connected with the power shaft 5. The vertical arms of the plurality of L-shaped frames are all arranged downward and connected and fixed by a reinforcing ring, and a mounting seam with a length of 123 mm, a width of 2 mm, and a depth of 4 mm is processed at the middle position of the outer side of the vertical arm of each L-shaped frame. A plurality of FEP paddles 7 are fixedly arranged on the outer side of the vertical arms of the plurality of L-shaped frames through the mounting seam. The plurality of FEP paddles 7 rotate with the rotor 6, and the FEP paddles 7 are 90 mm long, 60 mm wide, and 2 mm thick. Copper electrodes are fixedly arranged on the inner wall of the main cylinder of the outer shell 2. The copper electrodes are divided into two groups, one group at the top and one group at the bottom, and each group has 8 pieces. The copper electrodes in each group are connected by the tail, and each copper electrode is 100 mm long and 30 mm wide. During the rotation process, the outer edges of the multiple FEP paddles 7 contact and rub against the copper electrode. The effective friction area between each FEP paddle 7 and the copper electrode is (90*30) mm. 2 The housing top cover 8 is processed with a through hole with a diameter of 4 mm at a distance of 72 mm from the center, which is used to lead out the copper electrode connecting wire and connect it to the rectifier circuit inside the rectifier chamber 12-1.

[0039] Combination Figure 3-4 and Figure 7-Figure 8 As shown, the coupling ball mechanism 17 includes a guide pin, two counterweight balls and two return springs. The guide pin is inserted and fixed in a through hole radially arranged at the bottom of the power shaft 5 and is symmetrically arranged about the power shaft 5. The guide pin is 50 mm long and 7 mm in diameter. The two counterweight balls are integrally provided with a sleeve and are respectively slidably inserted at both ends of the guide pin. The outer diameter of the sleeve is 8 mm, the inner diameter is 7 mm, and the depth is 12 mm. A hanging ring is provided in the middle position of the outer wall of the sleeve. The two return springs are respectively obliquely connected between the power shaft 5 and the hanging rings corresponding to the two counterweight balls.

[0040] The driving gear 19 is located at the bottom of the main cylinder of the housing 2 and is placed on the surface of the housing chassis 14. The center hole of the driving gear 19 is sleeved on the power shaft 5. The driving gear 19 has a module of 4, a number of teeth of 40, a pressure angle of 20°, and a thickness of 10mm. A groove with a diameter of 132mm is processed on the upper end face of the driving gear 19, and four claws are arranged at equal angles on the inner wall of the groove. When the wind speed is high and the power shaft 5 drives the coupling ball mechanism 17 to move at high speed, the two counterweight balls will overcome the force of the return spring due to the centrifugal force and move outward along the guide pin until the two counterweight balls engage with any two opposite claws on the inner wall of the groove of the driving gear 19, so that the power shaft 5 can drive the driving gear 19 to rotate; when the wind speed is low and the power shaft 5 drives the coupling ball mechanism 17 to move at low speed, the centrifugal force of the two counterweight balls cannot overcome the force of the return spring or the moving distance cannot engage with the claws, then the power shaft 5 will not drive the driving gear 19 to rotate, and only control the rotation of the rotor 6.

[0041] The number of the driven gears 20 is consistent with the number of the secondary cylinders of the housing 2 and they are rotatably installed in the corresponding secondary cylinders through the driven shafts. The driven gears 20 are all meshed with the driving gears 19. The module of the driven gear 20 is 4, the number of teeth is 25, the pressure angle is 20°, and the thickness is 15mm. The center hole of the driven gear 20 has a diameter of 9mm and is processed with a keyway for key connection with the driven shaft. At the same time, a 2mm high boss is set on the top of the center hole of the driven gear 20 to support the magnet disk 22 to prevent it from directly contacting the upper end face of the driven gear 20. In addition, in order to reduce weight, the end face of the driven gear 20 can be hollowed out into a radial hub shape. The driven shaft is designed in the form of a stepped shaft, which is divided into three sections from the top to the bottom: Section I is 5mm long and 6mm in diameter, and this section is processed with a key structure for connecting with the keyway of the magnet disk 22; Section II is 40mm long and 9mm in diameter, and this section is processed with a key structure for connecting with the keyway of the driven gear 20; Section III is 8mm long and 12mm in diameter, and is matched with the bearing installed on the edge of the housing chassis 14. The magnet disk 22 has a diameter of 60mm and a thickness of 4mm. A through hole with a diameter of 6mm and a keyway are processed in the center of the magnet disk 22 for key connection with the driven shaft. A plurality of embedded grooves with a length of 15mm, a width of 10mm, and a depth of 2mm are circumferentially processed on the upper end surface of the magnet disk 22, and a magnet is embedded and fixed in each embedded groove. Coils are fixedly arranged in the secondary cylinder of the housing 2, and the driven gear 20 drives the magnet disk 22 to rotate through the driven shaft, and the coils cut the magnetic flux lines to generate induced current. The top of the secondary cylinder of the shell 2 is processed with a through hole with a diameter of 6 mm, which is used to lead out the coil connection wire and connect it to the rectifier circuit inside the rectifier compartment 12-1.

[0042] The movable traffic warning light of the present invention can be conveniently moved to a designated location by using a movable bracket, and the coupling of friction electrification and electromagnetic induction is realized through wind power generation equipment, so that the energy contained in breeze or gust of wind can be converted into electrical energy and stored in a battery, thereby supplying power to the traffic warning light. The specific power generation principle is: when the wind speed is low, the wind-driven rotating member 1 drives the adapter shaft 11 to rotate, generating torque, thereby transmitting the power shaft 5 to rotate through the coupling 10, and the rotor 6 spline-connected to the power shaft 5 inside the main cylinder of the outer shell 2 rotates accordingly. During the rotation process, the FEP paddles 7 around the rotor 6 cyclically contact the copper electrodes attached to the inner wall of the main cylinder of the outer shell 2 to generate friction current, and the friction current is connected to the rectifier bin 12-1 through the wires of the two groups of copper electrodes; when the wind speed is high, ... When the power shaft 5 drives the rotor 6 to rotate and generate friction current, because the power shaft 5 rotates at a higher speed, the weighted balls on both sides of the coupling ball mechanism 17 will overcome the force of the return spring under the action of centrifugal force and move outward along the guide pin until the two weighted balls engage with the two opposite claws on the inner side of the driving gear 19, so that the power shaft 5 drives the driving gear 19 to rotate at the same time. The driving gear 19 transmits the power to the driven gear 20 located in the auxiliary cylinder of the shell 2. The driven gear 20 drives the magnet disk 22 to rotate through the driven shaft connected by the center key. During the movement of the magnet embedded on the surface of the magnet disk 22, the coil attached to the inner wall of the auxiliary cylinder of the shell 2 cuts the magnetic flux line to generate induced current, which is led out through the wire of the coil and connected to the rectifier compartment 12-1. The rectifier circuit in the rectifier compartment 12-1 receives the friction current from the two sets of copper electrodes and the induced current from the coil and couples them, converts the AC into DC, and charges the battery in the battery compartment 12-2. The battery is connected to the control compartment through a wire, and the warning light 13 flashes under the control of the single-chip microcomputer.
