Description

Technical Field

[0001] This application relates to the field of construction warning signs, and in particular to an LED flashing construction warning sign with changeable content. Background Technology

[0002] In order to ensure the safety of the work area and passing vehicles, construction warning signs must be set up in front of the oncoming traffic as required. At present, most warning signs use angle steel as the load-bearing frame and aluminum plate as the backing for the reflective part, on which secondary reflective film with different warning content is pasted.

[0003] Different stages of construction require different warning messages, which means that construction units need to bring multiple warning signs with different content to the site. The workers then have to select and transport these signs, making the placement process cumbersome and reducing efficiency. In addition, the selection process can easily lead to safety hazards in the construction area due to the wrong signs being chosen. Warning signs mainly rely on passive reflection for warnings. In bad weather, at night, or when drivers are fatigued, the warning effect and visibility distance of passive reflection will decrease, thereby reducing the warning effect of the signs and consequently reducing the safety of the construction area. Utility Model Content

[0004] To address the issues of unchangeable warning sign content and reduced warning effectiveness at night, which lowers safety in construction areas, this application provides an LED flashing construction warning sign with changeable content.

[0005] The LED flashing construction warning sign with changeable content provided in this application adopts the following technical solution:

[0006] A type of LED flashing construction warning sign with changeable content includes a warning sign body, an LED display screen for displaying different warning content is provided on one side of the surface of the warning sign body, and blue flashing lights and red flashing lights are provided at the four corners of the warning sign body to remind drivers and passengers of construction ahead.

[0007] A control keypad for changing the content displayed on the LED display screen is provided on the side of the warning sign body away from the LED display screen.

[0008] By adopting the above technical solution, the LED display screen can be controlled by a control keyboard to provide different warning information to the warning sign body according to the changes in the construction stage. This enables the warning sign body to serve multiple purposes, improves the flexibility of the warning sign body during use, and provides a visual impact to drivers and passengers by flashing blue and red strobe lights during the use of the warning sign body, giving them an early warning and ensuring the safety of the construction area and drivers and passengers.

[0009] Preferably, a weight-increasing component for increasing the weight of the warning sign body is provided on one side of the surface of the warning sign body;

[0010] The weight-adding component includes weight-adding boxes disposed on both sides of the surface of the warning sign body. The interior of the weight-adding boxes has a weight-adding space for placing weight-adding media, and a cover plate is provided on one side of the surface of the weight-adding boxes.

[0011] By adopting the above technical solution, the weight of the warning sign body can be further increased by the weight-adding boxes on both sides of the surface of the warning sign body. At the same time, by placing the weight-adding medium inside the weight-adding space, the wind force of the area where the warning sign body can be placed can increase the weight differently, so that the warning sign body can remain stable when used in different wind areas, improving the stability of the warning sign body in warning the construction area. The top of the weight-adding space is sealed by the cover plate to prevent external objects from entering the weight-adding space.

[0012] Preferably, the weight-adding box has an outlet for discharging the weight-adding medium on the side of the surface away from the cover plate, a driving block is provided on the side of the weight-adding box away from the cover plate, and a sealing post is provided on the side of the driving block near the surface of the weight-adding box, which is located inside the outlet and is used to seal the outlet.

[0013] By adopting the above technical solution, the outlet is blocked by the sealing column to prevent the weight-adding medium from falling out of the weight-adding space and to avoid imbalance between the two sides of the warning sign body. At the same time, the discharge of the weight-adding medium can be controlled by driving the sealing column to rotate through the drive block.

[0014] Preferably, the weight-adding box has an insert block on the side of the surface near the warning sign body, the warning sign body has a socket for positioning the insert block on the side of the surface near the insert block, and the socket has a slot on the side of the surface near the insert block.

[0015] By adopting the above technical solution, the plug is inserted into the slot on the socket, thereby quickly connecting the plug and the slot, and thus the weight box is quickly installed on the side of the warning sign body near the socket.

[0016] Preferably, a handle is provided on the side of the cover plate away from the weight-adding box.

[0017] By adopting the above technical solution, the cover plate is no longer blocked from the top of the weight-adding space by pulling the handle upward, thereby adding the weight-adding medium into the weight-adding space.

[0018] Preferably, a PC endurance board protective screen for protecting the LED display screen is provided on the side of the LED display screen away from the warning sign body.

[0019] By adopting the above technical solution and setting a protective screen on the surface of the LED display screen, damage to the LED display screen from external objects can be avoided during use.

[0020] Preferably, a power supply box for providing power is provided on the side of the warning sign body away from the LED display screen. The power supply box is located below the control keyboard, and multiple rechargeable lithium batteries for providing power are installed inside the power supply box.

[0021] By adopting the above technical solution, multiple rechargeable lithium batteries provide power to the LED display screen while increasing the weight of the warning sign itself, reducing the risk of the warning sign being blown over by strong winds or airflow, and further improving the safety of the construction area.

[0022] Preferably, the warning sign body uses an aluminum plate as a substrate.

[0023] By adopting the above technical solution, the warning sign body uses an aluminum plate as a substrate, which allows users to process the surface of the warning sign body, and the warning sign body can avoid cracking or warping of the substrate due to changes in external temperature during use.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The LED display screen can be flexibly switched through the control buttons, replacing the traditional method of carrying multiple fixed content signs, which significantly improves the work efficiency of the warning signs in the construction area. At the same time, the four corners of the warning signs are equipped with blue and red strobe lights to enhance the visual impact on drivers and passengers, provide early warning to them, and thus improve the safety of the construction area.

[0026] 2. By using the removable rechargeable lithium battery in the power supply box and the removable installation of the weight-adding box, not only can the long-term continuous power supply requirements of the warning sign body be met, but also the weight-adding medium can be flexibly added according to the on-site wind conditions to realize the dynamic adjustment of the self-weight of the warning sign body, effectively resisting the airflow impact when strong winds or heavy vehicles pass by, ensuring that the warning sign body can remain stable and not fall over, and is suitable for different construction environments.

[0037] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0038] This application discloses an LED flashing construction warning sign with changeable content.

[0039] Reference Figures 1-3 A type of LED flashing construction warning sign with changeable content includes a warning sign body 1, which uses an aluminum plate as a base. The warning sign body 1 consists of four parts: graphic symbols or text, warning colors, a base plate, and a supporting structure. An LED display screen 2 for displaying different warning content is fixedly installed on one side of the warning sign body 1. A PC endurance board protective screen for protecting the LED display screen 2 is fixedly connected to the side of the LED display screen 2 away from the warning sign body 1. Blue flashing lights 3 and red flashing lights 4 are fixedly installed at the four corners of the warning sign body 1 to remind drivers and passengers of construction ahead. The specifications of the blue flashing lights 3 and red flashing lights 4 are 150*80mm. Figure 1 As shown, the blue strobe light 3 is installed at the upper right and lower left corners of the warning sign body 1, and the red strobe light 4 is installed at the upper left and lower right corners of the warning sign body 1.

[0040] A control keyboard 5 for changing the content displayed on the LED display screen 2 is fixedly connected to the side of the warning sign body 1 away from the LED display screen 2. A power supply box 6 for providing power is fixedly connected to the side of the warning sign body 1 away from the LED display screen 2. The power supply box 6 is located below the control keyboard 5. Multiple rechargeable lithium batteries for providing power are detachably installed inside the power supply box 6. The rechargeable lithium batteries have a size of 800*400*150mm and a weight of 6kg.

[0041] It should be noted that an STM32 series microcontroller is fixedly installed inside the warning sign body 1. The microcontroller is pre-loaded with information such as "Construction ahead 2000m", "Speed ​​limit 60", "No overtaking", and "Left lane closed". The microcontroller is located on the side of the LED display screen 2 closest to the warning sign body 1. The microcontroller is electrically connected to the LED display screen 2 and to the control keyboard 5. This connection method is existing technology, and the specific connection process and principle will not be detailed here. This allows the user to control the display content of the LED display screen 2 by operating the control keyboard 5.

[0042] An external infrared remote control module is connected to the microcontroller via GPIO pins to receive infrared coded signals from the remote control. This allows users to control the content displayed on the LED display screen 2 via both remote control and buttons. When button A on the infrared remote control is pressed, or button A on the control keyboard 5 is pressed, the LED display screen 2 displays "Construction ahead 2000m". When button B on the infrared remote control is pressed, or button B on the control keyboard 5 is pressed, the LED display screen 2 displays "Speed ​​limit 60".

[0043] The microcontroller is electrically connected to the blue strobe light 3 and the red strobe light 4. This connection method is existing technology. The specific connection process and principle will not be described in detail. The strobe interval of the blue strobe light 3 and the red strobe light 4 is 3-5 seconds. When the 3 button on the infrared remote control is pressed, the strobe interval of the blue strobe light 3 and the red strobe light 4 is 3 seconds.

[0044] The microcontroller also has a USB Type-C interface. When connected to the microcontroller, construction managers can import edited new warning content (such as specific road segment names or temporary notices) and display scheme configuration files into the microcontroller's memory via a USB flash drive, enabling flexible updates of warning content.

[0045] The LED display screen 2 can be controlled via the control keyboard 5 or infrared remote control to provide different warning information to the warning sign body 1 according to the changes in the construction stage, realizing the multi-purpose use of the warning sign body 1 and improving the flexibility of the warning sign body 1 in use. During the use of the warning sign body 1, the flashing interval of the blue strobe light 3 and red strobe light 4 can be controlled via the control keyboard 5 or infrared remote control, so that the flashing of the blue strobe light 3 and red strobe light 4 can provide visual impact to drivers and passengers, giving them an early warning and ensuring the safety of the construction area and drivers and passengers. At the same time, the removable rechargeable lithium battery inside the power box 6 can effectively ensure 24 / 7 power supply for operation while increasing the weight of the warning sign body 1, reducing the risk of the warning sign body 1 being blown over by strong winds or air currents, and further improving the safety of the construction area.

[0046] During use, when a construction vehicle is parked in the emergency lane, the worker can remotely control the warning sign body 1 to display the words "Construction ahead 2000m" on the LED display screen 2 and to make the blue strobe light 3 and red strobe light 4 flash, thereby speeding up the placement of the warning sign body 1 and making the placement of the warning sign body 1 quick and efficient, which can effectively improve work efficiency and construction safety.

[0047] Reference Figures 3-6 A weight-increasing component 7 for increasing the weight of the warning sign body 1 is provided on one side of the surface. The weight-increasing component 7 includes weight-increasing boxes 71 provided on both sides of the surface of the warning sign body 1. The weight-increasing boxes 71 have a weight-increasing space 711 for placing weight-increasing media inside. A cover plate 72 is hinged to the side of the weight-increasing box 71 near the top surface of the warning sign body 1. The side of the cover plate 72 away from the bottom surface of the warning sign body 1 is snapped to the top surface of the weight-increasing box 71 by a buckle. This snapping method is existing technology. The specific structure and working principle will not be described in detail. A handle is fixedly connected to the side of the cover plate 72 away from the surface of the weight-increasing box 71. The side of the handle away from the surface of the warning sign body 1 is in the shape of an inverted U.

[0048] The weight-adding box 71 has an outlet 712 for discharging the weight-adding medium on the side of the surface away from the cover plate 72. The outlet 712 is connected to the weight-adding space 711. A driving block 74 is abutted against the middle of the side of the weight-adding box 71 away from the cover plate 72. A sealing post 741 for blocking the outlet 712 is fixedly connected to the middle of the side of the driving block 74 near the surface of the weight-adding box 71. The surface of the sealing post 741 is provided with external threads. The inner wall of the outlet 712 is provided with internal threads that mesh with the external threads, so that the sealing post 741 can block the outlet 712 by meshing the external threads and internal threads. An insert block 713 is fixedly connected to the side of the weight-adding box 71 near the warning sign body 1. The side of the insert block 713 is shaped like the number 7.

[0049] A socket 73 for positioning the plug 713 is fixedly connected to the side of the warning sign body 1 near the surface of the plug 713. A slot 731 is provided on the side of the socket 73 near the surface of the plug 713. The end of the plug 713 away from the weight box 71 is inserted into the inside of the slot 731, so that the weight box 71 is inserted into the inside of the slot 731 through the plug 713 and quickly connected to the socket 73, so that the weight box 71 is quickly connected to both sides of the surface of the warning sign body 1. After the end of the plug 713 away from the weight box 71 is inserted into the inside of the slot 731, the surface of the end of the plug 713 away from the weight box 71 abuts against the inner wall of the slot 731.

[0050] When the weight of the warning sign body 1 cannot remain stable in the external environment, it is necessary to increase the weight of the warning sign body 1. The user inserts the plug 713 into the slot 731, so that the surface of the plug 713 abuts against the inner wall of the slot 731, thereby quickly attaching the weight-adding box 71 to both sides of the surface of the warning sign body 1. At this time, the weight of the weight-adding box 71, the cover plate 72, and the plug 713 are added to the original weight of the warning sign body 1.

[0051] When the original weight of the warning sign body 1 plus the weight of the weight-adding box 71, cover plate 72, and insert block 713 still cannot maintain stability in the external environment, the user needs to add weight-adding medium (water) into the weight-adding space 711. First, pull the handle on the side of the cover plate 72 away from the surface of the weight-adding box 71 to release the cover plate 72 from blocking the weight-adding space 711. Then, inject water into the weight-adding space 711 through the measuring cup to make the weight of the weight-adding medium in the weight-adding boxes 71 on both sides of the surface of the warning sign body 1 the same. After the injection is completed, pull the handle again to reseal the cover plate 72 in the weight-adding space 711, further increasing the weight of the warning sign body 1 and making the warning sign body 1 more stable when used in the external environment.

[0052] When it is necessary to drain the medium inside the weight-increasing space 711, the user only needs to manually rotate the drive block 74 counterclockwise to provide power to the sealing column 741, so that the drive block 74 drives the sealing column 741 to gradually detach from the inside of the outlet 712, thereby releasing the sealing column 741 from the outlet 712 and draining the water inside the weight-increasing space 711. This allows the user to freely adjust the weight of the warning sign body 1 according to the specific wind force in the construction area, so that the warning sign body 1 can remain stable under different wind conditions, avoiding the warning sign body 1 from tipping over due to excessive wind force, and ensuring the safety of the construction area.

[0053] It should be added that: the weight box 71, cover plate 72, and drive block 74 are made of aluminum alloy (e.g., 6061 aluminum alloy) that has been powder coated or anodized, while the plug block 713, socket 73, and sealing post 741 are made of stainless steel.

[0054] In this application, water or similar media are used as the weight-adding medium.

[0055] The implementation principle of the LED flashing construction warning sign with changeable content in this application embodiment is as follows: During use, the LED display screen 2, blue flashing light 3, and red flashing light 4 are controlled by an infrared remote control. The user operates the infrared remote control to make the LED display screen 2 display different warning content and control the flashing interval of the blue flashing light 3 and red flashing light 4, thereby speeding up the placement speed of the warning sign body 1, making the placement of the warning sign body 1 quick and efficient, and effectively improving work efficiency and construction safety.

[0056] Users can further increase the weight of the warning sign body 1 by using the weight-increasing component 7, so that the warning sign body 1 can adaptively adjust its weight according to the wind force in different construction areas, expand the application range of the warning sign body 1, and ensure that the warning sign body 1 can remain stable in different construction areas, ensuring the safety of the construction area and preventing outsiders from entering the construction area.

[0057] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
