Description

Technical Field

[0001] This invention relates to the field of traffic control technology, specifically to a traffic emergency indicator light. Background Technology

[0002] Traffic emergency traffic lights are temporary or mobile traffic signal devices used to ensure traffic order and safety in special circumstances. Traffic police departments may temporarily install fixed traffic lights when new roads open, existing traffic lights malfunction or require repair, or traffic flow at intersections changes temporarily. These traffic lights are typically connected to a power source via cables, are relatively fixed in location, and can reliably direct traffic for a certain period until the official traffic light system is restored to normal or a new traffic management plan is implemented.

[0003] Existing technology, such as the one disclosed in CN216848988U, discloses an intelligent traffic emergency traffic light, including a base plate. A battery box is fixedly connected to the top of the base plate, an electric telescopic rod is fixedly connected to the top of the battery box, a traffic light body is fixedly connected to the top of the electric telescopic rod, a placement box is fixedly connected to the right side of the traffic light body, a servo motor is fixedly connected to the bottom of the placement box, a screw is fixedly connected to the output end of the servo motor, a threaded sleeve is threaded onto the surface of the screw, a connecting rod is fixedly connected to the front surface of the threaded sleeve, and a brush plate is fixedly connected to the front side of the connecting rod. This utility model provides a placement box, a through groove, a servo motor, a screw, a connecting rod, a threaded sleeve, an electric telescopic rod, a screw hole, a threaded rod, an auxiliary plate, and an anti-slip pad, solving the problem that existing emergency traffic lights are inconvenient to use, reducing overall practicality and making them difficult for people to use.

[0004] A common problem with the aforementioned existing technologies is that, on roads in the morning and evening, east-west traffic is interfered with by sunlight that has a small angle with the ground. When the sunlight shines on the traffic light, it is reflected. Since the direction of the reflected light is similar to the direction in which drivers are looking at the traffic light, the traffic light becomes difficult to see, making it impossible to determine whether to proceed or wait. This situation affects road traffic and causes many inconveniences. Summary of the Invention

[0005] The purpose of this invention is to provide a traffic emergency indicator light to address the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a traffic emergency indicator light, including a base, a column that slides vertically on the base, and a three-lamp system on the four sides of the column, and further including a light-shielding component, a driving component, and a transmission component. The light-shielding component is disposed above each lamp body of a set of three-lamp systems, including a base plate rotatably connected to the column. Two telescopic rods are symmetrically slidably connected to the side of the base plate. An extension plate is fixedly connected to the telescopic part of the two telescopic rods. The driving component is controlled by a control system to drive the column to slide up and down. The transmission component is disposed on the column and the base plate. The column rises and falls, and the base plate rotates through the transmission component. At the same time, the telescopic rods slide away from the column, and the extension of the telescopic rods drives the extension plate to slide. At noon, the base plate is perpendicular to the side of the column. In the morning or evening, the base plate rotates downward to form an acute angle with the side of the column. The extension plate moves relative to the base plate to cooperate with the base plate to block sunlight. The rotation amplitude of the base plate is controlled by the control system.

[0007] Furthermore, the transmission component includes a rotating wheel, a first gear, and a gear ring. The rotating wheel is rotatably connected to the cylinder, and a first pull rope is wound around it. The end of the first pull rope away from the rotating wheel is fixedly connected to the base. The first gear is coaxially fixedly connected to the rotating wheel. The gear ring is fixedly connected to one end of the base plate extending into the cylinder and meshes with the first gear.

[0008] Furthermore, a torsion spring is installed on the wheel for its reset.

[0009] Furthermore, the three first pull ropes on the same side converge into one at the bottom.

[0010] Furthermore, the transmission component also includes a tensioning wheel, which is coaxially and fixedly connected to the rotating wheel. Two tensioning wheels are symmetrically fixed on both sides of each rotating wheel. A second pull rope is wound on each tensioning wheel. Each second pull rope is fixedly connected to a slider after being guided by two fixed pulleys. The slider is fixedly connected to the sleeve of the telescopic rod.

[0011] Furthermore, the light-shielding assembly also includes grooves formed on both sides of the substrate, a sleeve is slidably installed in the groove, a first rack is fixed on the groove, a second gear is rotatably installed on the sleeve, the second gear meshes with the first rack, and a second rack is fixedly connected to the telescopic part, the second rack meshes with the second gear.

[0012] Furthermore, an elastic element is provided between the substrate and the slider for resetting the slider.

[0013] Furthermore, the extension plate has an arc-shaped structure.

[0014] Furthermore, the lifting assembly includes an electro-hydraulic push rod fixedly mounted on the base, the telescopic end of which is fixedly connected to the column, and it is powered by a power source within the base and its telescopic movement is controlled by a control system.

[0015] Furthermore, the lifting assembly includes a linear motor fixedly mounted on the base, with its telescopic end fixedly connected to the column. It is powered by a power source within the base, and its telescopic movement is controlled by a control system.

[0016] In the above technical solution, the present invention provides a traffic emergency indicator light. Under the control of the control system, the height of the column is adjusted by the driving component according to the time change. The angle between the base plate and the extension plate and the extension distance of the extension plate are adjusted synchronously. In the morning and evening, when the angle between the sunlight and the ground is small, it is easy to shine on the light body and reflect to the driver's position. At this time, the base plate and the extension plate rotate to the maximum angle and the extension distance of the extension plate is the longest. At this time, the sunlight coming from the angle is blocked by the base plate and the extension plate. It is worth mentioning that the tilt direction of the base plate and the extension plate and the height of the column are adapted in real time to the light body to radiate the signal light to the driver's position. It will not obstruct the radiation of the signal light to the driver. Moreover, the tilt angle of the base plate and the extension plate is controlled by the control system to adapt to the angle of the sunlight in real time. By adapting the column to a suitable height of rise or fall, the signal light of the light body is not disturbed when it is radiated to the driver, avoiding the impact on road traffic when the light intensity is high in the morning or evening.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-9 The present invention provides a traffic emergency indicator light, including a base 1 with casters, and a column 2 slidably connected vertically on the base 1. The column 2 is used to install a three-light system on four sides. The three-light system is controlled by a power supply and control system (not shown in the figure) installed in the base 1 to display light signals.

[0031] It also includes a light-shielding component 4, a lifting component, and a transmission component 6. The lifting component is a driving component 5, which is powered by a power source in the base 1 and controlled by a control system to manipulate the lifting and lowering of the column 2. The light-shielding component 4 is installed on each lamp body 3 of the two sets of three-lamp systems in the east-west direction (the north-south direction is basically unaffected by sunlight reflection). It includes a base plate 41 and an extension plate 42. The base plate 41 is rotatably connected to the column 2. The extension plate 42 is movably connected to the base plate 41 through two telescopic rods 43 that are slidably connected to the side of the base plate 41. Each extension plate 42 is fixedly connected to the telescopic ends of the two telescopic rods 43 in the same group. In this embodiment, the driving component 5 is an electro-hydraulic push rod 51.

[0032] The transmission component 6 is disposed on the column 2 and the base plate 41. When the column 2 rises or falls, the transmission component 6 can make the base plate 41 and the extension plate 42 rotate synchronously along the rotation connection axis of the base plate 41. At the same time as the base plate 41 and the extension plate 42 rotate, the light shielding component 4 causes the telescopic rod 43 to slide away from the column 2 and the telescopic end to extend, thereby driving the extension plate 42 to move obliquely downward relative to the base plate 41.

[0033] In the above technical solution, the height of the column 2 is adjusted by the drive component 5 according to the time changes under the control of the control system. The angle between the base plate 41 and the extension plate 42 and the extension distance of the extension plate 42 are adjusted synchronously. In the morning and evening, when the angle between the sunlight and the ground is small, it is easy to shine on the lamp body 3 and reflect to the driver's position. At this time, the base plate 41 and the extension plate 42 rotate to the maximum angle and the extension distance of the extension plate 42 is the longest. At this time, the sunlight that is tilted is blocked by the base plate 41 and the extension plate 42. It is worth mentioning that the tilt direction of the base plate 41 and the extension plate 42 is adapted to the height of the column 2 in real time so that the lamp body 3 emits signal light to the driver's position. It will not obstruct the radiation of the signal light to the driver. Moreover, the tilt angle of the base plate 41 and the extension plate 42 is controlled by the control system to adapt to the angle of the sunlight in real time. Then, by adjusting the column 2 to a suitable height, the signal light of the lamp body 3 is not disturbed when it shines on the driver, avoiding the impact on road traffic when the light intensity is high in the morning or evening.

[0034] In another embodiment, the driving component 5 is selected as a linear motor 52, which is fixedly connected to the base 1. The telescopic end of the linear motor 52 is fixedly connected to the column 2. Of course, the linear motor 52 can be replaced by other driving components 5 that can drive the column 2 to move up and down, all of which are within the protection scope of this application.

[0035] The transmission component 6 includes a rotating wheel 61, a first pull rope 62, a first gear 63, and a toothed ring 64. The rotating wheel 61 is rotatably connected inside the column 2. The first pull rope 62 is wound around the rotating wheel 61. The end of the first pull rope 62 away from the rotating wheel 61 is fixedly connected to the base 1. The transmission component 6 is arranged next to each group of light-shielding components 4. The first pull ropes 62 in the same vertical column are merged into one strand at the bottom. The first gear 63 is coaxially fixedly connected to the rotating wheel 61, and the tooth tip circle diameter of the first gear 63 is smaller than the diameter of the rotating wheel 61. The toothed ring 64 is a quarter ring, which is fixedly connected to the base plate 41, and the axis of the toothed ring 64 coincides with the axis of rotation of the base plate 41.

[0036] During the upward movement of the column 2 driven by the drive component 5, the first pull rope 62 is fixedly connected to the base 1, the wheel 61 is driven to rotate, which in turn drives the first gear 63 to rotate. The first gear 63 drives the meshing gear ring 64 to rotate. The rotation of the gear ring 64 can drive the base plate 41 fixedly connected to the gear ring 64 to rotate. The rotation and amplitude of the above components are controlled by the step amount of the drive component 5. The drive component 5 precisely controls the movement of the above components under the control of the control system.

[0037] The light-shielding component 4 also includes a slide groove 44, a first rack 45, a second gear 46, and a second rack 47. The slide groove 44 is formed on both sides of the substrate 41. The first rack 45 is fixedly connected to the slide groove 44. The second gear 46 is rotatably connected to the sleeve 431 of the telescopic rod 43 and meshes with the first rack 45. The second rack 47 is fixedly connected to the telescopic part 432 of the telescopic rod 43 and also meshes with the second gear 46. When the transmission member 6 drives the sleeve 431 of the telescopic rod 43 to move, due to the meshing of the first rack 45 and the second gear 46, the first rack 45 drives the second gear 46 to rotate. Consequently, the second gear 46 drives the second rack 47 to slide. The second rack 47 drives the telescopic part 432 to slide downward. The downward sliding of the telescopic part 432 simultaneously drives the extension plate 42 to slide downward relative to the substrate 41.

[0038] The transmission component 6 also includes a tightening wheel 65, a second pull rope 66, a fixed pulley 67, and a slider 68. The tightening wheel 65 is coaxially and fixedly connected to the rotating wheel 61. When the first pull rope 62 pulls the rotating wheel 61 to rotate, the tightening wheel 65 rotates at the same angular velocity. The second pull rope 66 is wound around the tightening wheel 65. After being guided by the fixed pulley 67 rotatably connected to the base plate 41, the other end of the second pull rope 66 is fixed to a slider 68. The slider 68 is slidably connected to the base plate 41. The second gear 46 is rotatably connected to the slider 68. The slider 68 is fixed relative to the sleeve 431. When the rotating wheel 61 is rotated by the combined force of the driving component 5 and the first pull rope 62, it drives the tightening wheel 65 to rotate. The rotation of the tightening wheel 65 pulls the second pull rope 66 to wind around the tightening wheel 65. The second pull rope 66 then pulls the slider 68 to slide. The slider 68 synchronously drives the sleeve 431 to move. Thus, the transmission component 6 transmits force to the light-shielding component 4 through the slider 68.

[0039] It is worth mentioning that a torsion spring 611 is coaxially mounted on the rotating wheel 61, and an elastic element is also provided between the base plate 41 and the slider 68. In this embodiment, the elastic element is a tension spring 69. When the transition from morning to noon, the drive member 5 is controlled by the control system to slowly drive the column 2 to move down. During the downward movement of the column 2, the elastic potential energy of the torsion spring 611 is released, which drives the rotating wheel 61 to rotate and tightens the first pull rope 62. At this time, the tightening wheel 65 is also driven to rotate, the second pull rope 66 is relaxed, the elastic potential energy of the tension spring 69 is released, which drives the slider 68 to slide towards the column 2, and then drives the sleeve 431 and the telescopic part 432 to slide towards the column 2 in sync. Then, through the transmission of the second gear 46, the first rack 45 and the second rack 47, the extension plate 42 is driven to slide towards the base plate 41.

[0040] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
