Description

Technical Field

[0001] This invention relates to the field of radio speed measurement, and more particularly to a radar speed measurement device for road traffic. Background Technology

[0002] To ensure traffic safety, different speed limits are set for different road sections. To regulate driver behavior and ensure compliance with these speed limits, radar speed measuring devices and speed camera (or video recording) devices are often installed on these sections to measure vehicle speeds and record speeding violations, thus penalizing drivers and serving as a warning. However, existing radar speed measuring devices in more remote areas are often supplemented by solar or wind power generation because they are far from the power grid and cannot be powered by it. However, due to the remoteness of these areas, many large vehicles (such as dump trucks and heavy trucks) often pass through these sections, generating significant dust. This dust can easily cover the solar panels and speed limit signs, affecting the power generation of the solar panels and the driver's visibility of the signs, thus hindering their warning effect and highlighting their shortcomings. Summary of the Invention

[0003] The purpose of this invention is to provide a radar speed measurement device for road traffic to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A radar speed measuring device for road traffic includes a main housing, transmission balls, hollow shafts, a main support plate, an upper transmission shaft, pinions, limiting plates, a transmission seat, a photovoltaic panel, a secondary support plate, a bamboo-joint tube, a secondary housing, a limiting seat, an upper electric push rod, an upper controller, a rear hinge seat, a front hinge seat, a lower electric push rod, a rack, a conductive part, and a control part.

Each hollow shaft is fixed with a main support plate and has an upper transmission shaft mounted on it. Each hollow shaft is coaxially fixed with a pinion and a vertical limiting plate. Each upper transmission shaft rotates and slides coaxially with the hollow shaft and is horizontally hinged to the transmission seat at equal circumferential angles. A horizontal photovoltaic panel is fixed to the top of the main support plate. A horizontal secondary support plate is fixed to the upper part of the inner wall of the main housing, and a vertical bamboo tube is fixed to the top of the secondary support plate. A vertical secondary housing is slidably connected to the main housing, and multiple horizontal limiting seats are fixed at equal angles on the inner circumference of the secondary housing.

A vertical generator is fixed in the middle of the support frame, and a horizontal support shaft is fixed at the bottom. A worm gear is coaxially fixed in the middle of the support shaft, and a support seat is hinged to it. A horizontal servo motor is fixed at the rear end of the support seat, and a photosensitive sensor is fixed at the front of the bottom end. A vertical lower drive shaft is rotatably connected to the rear of the support seat. An upper gear is coaxially fixed at the lower part of the lower drive shaft. A worm gear is coaxially fixed to the shaft of the servo motor. Horizontal fastening bolts are threaded to the left and right sides of the support seat, and horizontal clamping seats are rotatably connected to the two fastening bolts.

[0006] Based on the above technical solution, the control unit includes a support column, a locking disc, a base, locking protrusions, a transmission cylinder, an upper gear ring, a lower gear ring, a locking clamp, a marker plate, a guide seat, a display screen, a radar speedometer, a lower controller, a monitoring camera, a battery, a transmission screw, a lower gear, and a cleaning rack. A vertical support column is rotatably connected to the bottom of the support base. A locking disc is coaxially fixed to the upper part of the support column, and a base is fixed to its bottom. Multiple vertical locking protrusions are fixed at equal angles on the outer circumference of the locking disc. A transmission cylinder is coaxially rotatably connected to the upper part of the support column. The upper part of the transmission cylinder... The upper gear ring is fixed to the shaft, and the lower gear ring is coaxially fixed to the bottom. Two horizontal locking hoops are bolted to the middle of the support column. The front ends of the two locking hoops are jointly fixed to an indicator plate, and the rear ends are jointly fixed to a vertical guide seat. The bottom of the indicator plate is fixed to a display screen, and the upper part is fixed to a radar speed detector, a lower controller, and a monitoring camera. The rear end of the indicator plate is fixed to a battery. The guide seat is rotatably connected to a vertical transmission screw. The upper part of the transmission screw is coaxially fixed to a lower gear, and a horizontal cleaning frame is threadedly connected to it. The cleaning frame is slidably connected to the guide seat and the indicator plate.

[0007] Based on the above technical solution, the bottom end of the main housing is fixed to the rotating shaft of the generator; each of the pinions meshes with each rack; the positive electrode of each photovoltaic panel is electrically connected to the upper positive electrode contact ring; the negative electrode of each photovoltaic panel is electrically connected to the upper negative electrode contact ring; the top end of the bamboo-shaped tube is fixed to the top end of the inner wall of the sub-housing; the top end of the upper electric push rod is fixed to the sub-housing; the upper electric push rod, the upper controller, and the lower electric push rod are electrically connected; the positive electrode of the upper controller is electrically connected to the lower positive electrode contact ring; the negative electrode of the upper controller is electrically connected to the lower negative electrode contact ring; the upper positive electrode contact ring, the upper... The negative electrode contact ring, lower positive electrode contact ring, lower negative electrode contact ring, and contact piece are all made of conductive material. The upper positive electrode contact ring, upper negative electrode contact ring, lower positive electrode contact ring, and lower negative electrode contact ring respectively contact the contact piece to achieve electrical connection. Each contact piece is electrically connected to the lower controller. The generator, servo motor, photosensitive sensor, display screen, radar speedometer, lower controller, monitoring camera, and battery are electrically connected. The worm gear meshes with the worm. The lower transmission shaft and the servo motor shaft are meshed and transmitted through a bevel gear. The upper gear meshes with the upper gear ring, and the lower gear ring meshes with the lower gear.

[0008] Based on the above technical solution, when the main housing rotates, it can drive the generator to rotate and generate electricity. When the upper electric push rod is energized and extends, it can drive the secondary housing to slide up and down along the main housing. The upper controller and the lower controller can transmit radio signals to each other. When the lower electric push rod is energized and extends, it can cause the transmission seat to rotate. When the transmission seat rotates, it can drive the transmission ball to rotate through the upper transmission shaft and the hollow shaft, thereby changing the horizontal angle between each hollow shaft and the main housing. When the transmission seat rotates, it can cause the pinion and rack to disengage and engage, while simultaneously achieving a horizontal sliding connection between the limiting plate and the limiting seat. The hollow shaft is oriented relative to the main housing. When the pinion is set, the pinion meshes with the rack, causing the limit plate to disengage from the limit seat and slide horizontally. When the servo motor is powered on and rotates in both directions, it can drive the support frame to swing back and forth through the support shaft, worm gear, and worm. When the servo motor is powered on and rotates in both directions, it can drive the transmission cylinder to rotate in both directions through the bevel gear, lower transmission shaft, upper gear, and upper gear ring. When the transmission cylinder rotates in both directions, it can drive the transmission screw to rotate in both directions through the lower gear ring and lower gear. When the transmission screw rotates in both directions, it can drive the cleaning frame to slide up and down along the guide seat. When the fastening bolt rotates in both directions, it can drive the clamping seat to move left and right. Under the push of the two fastening bolts, the two clamping seats can be clamped to the outer wall of the locking disc.

[0009] Compared with the prior art, the present invention has the following advantages: The present invention indirectly drives the transmission seat to rotate by controlling the extension and retraction of the lower electric push rod, thereby making the main support plate eccentrically positioned relative to the main housing. Furthermore, by controlling the extension and retraction of the upper electric push rod, the horizontal and vertical states of the main support plate can be indirectly changed. When the main support plate is vertical and eccentrically positioned relative to the main housing, it can be blown by horizontal wind, thereby driving the main housing and generator to rotate and achieve wind power generation. During the rotation process, the wind can also be used to remove dust covering the photovoltaic panel surface. A certain amount of air blowing is required to facilitate the next photovoltaic power generation. The horizontally oriented photovoltaic panels, in conjunction with the indirect drive of the servo motor, can gradually face the sun, thereby achieving good photovoltaic power generation. When the horizontally oriented photovoltaic panels face downwards, they can avoid being covered by snow, thus preventing the photovoltaic panels from being covered by snow that cannot melt quickly and affecting subsequent photovoltaic power generation. When the servo motor rotates forward and backward, it can indirectly drive the cleaning rack to slide up and down along the signboard and guide seat, thereby cleaning the signboard and display screen, and ensuring that the signboard and display screen can provide long-term and stable warning functions.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-7As shown, a radar speed measuring device for road traffic includes a main housing 1, transmission balls 2, hollow shafts 3, main support plates 4, upper transmission shafts 5, pinions 6, limiting plates 7, transmission seats 8, photovoltaic panels 9, secondary support plates 10, bamboo-joint tubes 11, secondary housings 12, limiting seats 13, upper electric push rods 14, upper controllers 15, rear hinge seats 16, front hinge seats 17, lower electric push rods 18, racks 19, conductive parts 20, and control parts 21. The main housing 1 is rotatably connected to multiple transmission balls 2 at equal circumferential angles. Each transmission ball 2 is fixed with a horizontal hollow shaft 3. Each hollow shaft 3 is fixed with a main support plate 4 and has an upper transmission shaft 5 mounted on it. Each hollow shaft 3 is coaxially fixed with a pinion 6 and a vertical limiting plate 7. Each upper transmission shaft 5 rotates and slides coaxially with the hollow shaft 3 and is horizontally hinged to the transmission seat 8 at equal circumferential angles. Each of the main support plates 4 has a horizontal photovoltaic panel 9 fixed at its top. The upper part of the inner wall of the main housing 1 has a horizontal secondary support plate 10 fixed, and a vertical bamboo tube 11 fixed at its top. The main housing 1 is slidably connected to a vertical secondary housing 12, and multiple horizontal limiting seats 13 are fixed at equal angles around its inner wall. The secondary support plate 10 is rotatably connected to the transmission seat 8, and a vertical upper electric push rod 14 is fixed in the middle. An upper controller 15 is fixed at the top of the secondary support plate 10. A horizontal rear hinge seat 16 is fixed at the rear end of the inner wall of the main housing 1. A horizontal front hinge seat 17 is hinged to the rear hinge seat 16. A horizontal lower electric push rod 18 is fixed at the front end of the front hinge seat 17. The push rod of the lower electric push rod 18 is hinged to the transmission seat 8. Multiple vertical racks 19 are fixed at equal angles around the circumference of the secondary housing 12. A conductive part 20 and a control part 21 are installed at the bottom of the main housing 1.

[0020] The conductive part 20 includes an upper positive contact ring 22, an upper negative contact ring 23, a lower positive contact ring 24, a lower negative contact ring 25, an insulating pad 26, a support frame 27, a protective cylinder 28, a spring plate 29, a contact plate 30, a generator 31, a support shaft 32, a worm gear 33, a support base 34, a servo motor 35, a photosensitive sensor 36, a lower transmission shaft 37, an upper gear 38, a worm gear 39, a fastening bolt 40, and a clamping seat 41. The bottom of the main housing 1 is fixed with the upper positive contact ring 22, the upper negative contact ring 23, the lower positive contact ring 24, the lower negative contact ring 25, an insulating pad 26, a support frame 27, a protective cylinder 28, a spring plate 29, a contact plate 30, a generator 31, a support shaft 32, a worm gear 33, a support base 34, a servo motor 35, a photosensitive sensor 36, a lower transmission shaft 37, an upper gear 38, a worm gear 39, a fastening bolt 40, and a clamping seat 41, from top to bottom. The upper positive contact ring 22, upper negative contact ring 23, lower positive contact ring 24, and lower negative contact ring 25 are separated by insulating pads 26. The insulating pads 26 prevent short circuits among these rings. A vertical support frame 27 is rotatably connected to the bottom of the main housing 1, and a vertical protective cylinder 28 is fixed to the upper part of the support frame 27. The upper circumference is fixed with four vertical spring plates 29 of different heights at equal angles. The protective sleeve 28 protects the upper positive contact ring 22, upper negative contact ring 23, lower positive contact ring 24, lower negative contact ring 25, spring plates 29, and contact plates 30, preventing dust and other debris from interfering with electrical conduction. Each spring plate 29 is fixed with a contact plate 30. A vertical generator 31 is fixed in the middle of the support frame 27, and a horizontal support shaft 32 is fixed at the bottom. The middle of the support shaft 32 is... A worm gear 33 is fixed to the shaft and a support base 34 is hinged to it. A horizontal servo motor 35 is fixed to the rear end of the support base 34 and a photosensitive sensor 36 is fixed to the front bottom end. A vertical lower drive shaft 37 is rotatably connected to the rear of the support base 34. An upper gear 38 is coaxially fixed to the lower part of the lower drive shaft 37. A worm gear 39 is coaxially fixed to the shaft of the servo motor 35. Horizontal fastening bolts 40 are threaded to the left and right sides of the support base 34. Horizontal clamping seats 41 are rotatably connected to the two fastening bolts 40 respectively.

[0021] The control unit 21 includes a support column 42, a locking disc 43, a base 44, locking protrusions 45, a transmission cylinder 46, an upper gear ring 47, a lower gear ring 48, a locking clamp 49, a marker plate 50, a guide seat 51, a display screen 52, a radar speedometer 53, a lower controller 54, a monitoring camera 55, a battery 56, a transmission screw 57, a lower gear 58, and a cleaning rack 59. The bottom of the support base 34 is rotatably connected to a vertical support column 42. A locking disc 43 is coaxially fixed to the upper part of the support column 42, and a base 44 is fixed to its bottom end. Multiple vertical locking protrusions 45 are fixed at equal angles on the outer circumference of the locking disc 43. These locking protrusions 45 increase the friction between the clamping seat 41 and the locking disc 43 when clamped, preventing the support base 34 from accidentally rotating left or right relative to the locking disc 43 and the support column 42. This ensures that the photovoltaic panel 9 moves in sync with the swing of the support base 34. To ensure the system faces the sun and avoids accidental lateral movement that could affect power generation efficiency, the upper part of the support column 42 is coaxially rotatably connected to a transmission cylinder 46. The upper part of the transmission cylinder 46 is coaxially fixed to an upper gear ring 47, and the bottom is coaxially fixed to a lower gear ring 48. Two horizontal locking hoops 49 are bolted to the middle of the support column 42. The front ends of the two locking hoops 49 are jointly fixed to an indicator plate 50, and the rear ends are jointly fixed to a vertical guide seat 51. The bottom of the indicator plate 50 is fixed to a display screen 52, and the upper part is fixed to a radar speed meter 53, a lower controller 54, and a monitoring camera 55. The rear end of the indicator plate 50 is fixed to a battery 56. The guide seat 51 is rotatably connected to a vertical transmission screw 57. The upper part of the transmission screw 57 is coaxially fixed to a lower gear 58, and a horizontal cleaning frame 59 is threadedly connected to it. The cleaning frame 59 is slidably connected to the guide seat 51 and the indicator plate 50.

[0022] The bottom end of the main housing 1 is fixed to the rotating shaft of the generator 31. Each of the pinions 6 meshes with each rack 19. The positive terminal of each photovoltaic panel 9 is electrically connected to the upper positive contact ring 22, and the negative terminal of each photovoltaic panel 9 is electrically connected to the upper negative contact ring 23. The top end of the bamboo tube 11 is fixed to the top end of the inner wall of the sub-housing 12. The bamboo tube 11 can protect the inside of the main housing 1, preventing dust and other debris from entering and interfering with the transmission of the hollow shaft 3 and the upper drive shaft 5. The top end of the upper electric push rod 14 is fixed to the sub-housing 12. The upper electric push rod 14, the upper controller 15, and the lower electric push rod 18 are electrically connected. The positive terminal of the upper controller 15 is electrically connected to the lower positive contact ring 24, and the negative terminal of the upper controller 15 is electrically connected to the lower negative contact ring 25. The upper positive contact ring 22, the upper negative contact ring 23, the lower positive contact ring 24, and the lower negative contact ring 25 are all connected. Both contact 5 and contact piece 30 are made of conductive material. The upper positive contact ring 22, upper negative contact ring 23, lower positive contact ring 24 and lower negative contact ring 25 are respectively in contact with contact piece 30 to achieve electrical connection, thereby ensuring that the main housing 1 can still conduct electrical energy well when rotating, that is, it can transmit the electricity generated by photovoltaic panel 9 to lower controller 54, and can transmit electrical energy to upper controller 15 through lower controller 54. Each contact piece 30 is electrically connected to lower controller 54. The generator 31, servo motor 35, photosensitive sensor 36, display screen 52, radar speedometer 53, lower controller 54, monitoring camera 55 and battery 56 are electrically connected. The worm gear 33 meshes with worm 39. The lower transmission shaft 37 and the rotating shaft of servo motor 35 are meshed and transmitted through bevel gear. The upper gear 38 meshes with upper gear ring 47, and the lower gear ring 48 meshes with lower gear 58.

[0023] When the main housing 1 rotates, it drives the generator 31 to rotate and generate electricity. When the upper electric push rod 14 is energized and extends, it drives the secondary housing 12 to slide up and down along the main housing 1. The upper controller 15 and the lower controller 54 can transmit radio signals to each other. When the lower electric push rod 18 is energized and extends, it causes the transmission seat 8 to rotate. When the transmission seat 8 rotates, it drives the transmission ball 2 to rotate through the upper transmission shaft 5 and the hollow shaft 3, thereby changing the horizontal angle between each hollow shaft 3 and the main housing 1. When the transmission seat 8 rotates, it causes the pinion 6 to disengage from the rack 19 and simultaneously achieves a horizontal sliding connection between the limiting plate 7 and the limiting seat 13. The horizontal sliding connection between the limiting plate 7 and the limiting seat 13 can limit the posture of the limiting plate 7, thereby limiting the posture of the main support plate 4 and the photovoltaic panel 9. When the hollow shaft 3 is arranged radially relative to the main housing 1, the pinion 6 meshes with the rack 19, causing the limiting plate 7 to disengage from the horizontal sliding connection with the limiting seat 13. When the servo motor 35 is powered on and rotates in both directions, it can drive the support frame 27 to swing back and forth through the support shaft 32, worm gear 33 and worm 39. When the servo motor 35 is powered on and rotates in both directions, it can drive the transmission cylinder 46 to rotate in both directions through the bevel gear, lower transmission shaft 37, upper gear 38 and upper gear ring 47. When the transmission cylinder 46 rotates in both directions, it can drive the transmission screw 57 to rotate in both directions through the lower gear ring 48 and lower gear 58. When the transmission screw 57 rotates in both directions, it can drive the cleaning rack 59 to slide up and down along the guide seat 51. When the fastening bolt 40 rotates in both directions, it can drive the clamping seat 41 to move left and right. Under the push of the two fastening bolts 40, the two clamping seats 41 can be clamped on the outer wall of the locking disc 43.

[0024] The working principle of this invention is as follows: Initially, the photovoltaic panel 9 faces the sky and is in a horizontal position. The hollow shaft 3 is set centripetally relative to the main housing 1. In use, the base 44 is fixed to the side of the road by bolts or other connecting parts or other methods, so that the front end of the signboard 50 faces the direction of oncoming traffic. Then, the horizontal angle of the support seat 34 on the support column 42 is adjusted. Then, the fastening bolt 40 is rotated to clamp the locking plate 43 with the clamping seat 41, thereby limiting the horizontal angle of the support seat 34. The front end of the signboard 50 is used to indicate the speed limit. The radar speed detector 53 measures the speed of passing vehicles and displays the speed value on the display screen 52 to remind and warn the driver. Then, the monitoring camera 55 takes pictures and records the vehicles, and the relevant information is transmitted to the signal station wirelessly through the lower controller 54.

[0025] When it is daytime, the photosensitive sensor 36 senses the light and transmits a signal to the lower controller 54, which then controls the servo motor 35 to rotate in the forward direction. This causes the support base 34 to swing towards the sun using the worm gear 39 and worm wheel 33, thereby making the photovoltaic panel 9 face the sun and improving the power generation efficiency of the photovoltaic panel 9.

[0026] In a dark environment, the photosensitive sensor 36 cannot detect light. The photosensitive sensor 36 transmits a signal to the lower controller 54, which then controls the servo motor 35 to rotate in the opposite direction, thus restoring the photovoltaic panel 9 to a horizontal position. Subsequently, the lower controller 54 transmits a radio signal to the upper controller 15, which then controls the upper electric push rod 14 to extend, causing the sub-housing 12 and rack 19 to move upwards. This, in turn, causes the hollow shaft 3 to rotate due to the meshing of the rack 19 with the pinion 6, thereby causing the main... The support plate 4 and photovoltaic panel 9 are in a vertical position. Then, the upper controller 15 controls the lower electric push rod 18 to retract, thereby enabling the transmission seat 8 to rotate forward. This causes the main support plate 4 to gradually become eccentric relative to the main housing 1 through the upper transmission shaft 5 and hollow shaft 3. During this process, the pinion 6 disengages from the rack 19 and simultaneously causes the limiting plate 7 to slide horizontally with the limiting seat 13, thus ensuring that the main support plate 4 remains vertical. At this point, the main support plate 4 is again eccentric relative to the main housing 1. The main support plate 4 and photovoltaic panel 9 are rotated by the horizontal wind, causing the main casing 1 to rotate, which in turn causes the generator 31 to rotate, thus generating wind power. The eccentrically positioned main support plate 4 can rotate the main casing 1 regardless of the horizontal wind direction, facilitating wind power generation. In this state, the photovoltaic panel 9 moves synchronously with the main support plate 4, thus maintaining a vertical position, reducing dust accumulation, and being blown by the wind during movement, thereby clearing away dust that would accumulate when the panel is horizontal. The system is cleaned to facilitate the next photovoltaic power generation. When the photosensitive sensor 36 senses light again, under the control of the lower controller 54 and the upper controller 15, the push rod of the lower electric push rod 18 extends, causing the transmission seat 8 to reverse, thereby restoring the meshing of the pinion 6 and the rack 19, and causing the limit plate 7 to disengage from the limit seat 13. Then the push rod of the upper electric push rod 14 retracts, thereby using the meshing of the rack 19 and the pinion 6 to make the hollow shaft 3 rotate, so that the photovoltaic panel 9 faces the sky again, and then generates photovoltaic power again.

[0027] When it is snowing, the signal station transmits a snowfall signal to the lower controller 54. After receiving the signal, the lower controller 54 transmits a radio signal to the upper controller 15, which in turn controls the upper electric push rod 14 to retract. Then, through the meshing of the rack 19 and the pinion 6, the hollow shaft 3 rotates, so that the photovoltaic panel 9 faces downward, preventing the photovoltaic panel 9 from being covered by snow and unable to melt in a short time, thus affecting subsequent photovoltaic power generation.

[0028] During forward and reverse rotation, the servo motor 35 drives the lower transmission shaft 37 to rotate in both directions via the bevel gear. This, in turn, drives the transmission cylinder 46 to rotate in both directions via the upper gear 38 and the upper gear ring 47. In turn, the transmission cylinder 46 drives the transmission screw 57 to rotate in both directions via the lower gear ring 48 and the lower gear 58. This causes the cleaning rack 59 to slide up and down along the signboard 50 and the guide seat 51, thereby wiping the signboard 50 and ensuring that the signboard 50 and the display screen 52 can provide long-term and stable warning functions.

[0029] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
