Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to an electrical safety warning sign. Background Technology

[0002] In power facilities and electrical work scenarios, electrical safety warning signs are crucial equipment for ensuring personnel safety and preventing accidents such as electric shock. However, existing electrical safety warning signs generally suffer from problems such as limited functionality and unreasonable structural design.

[0003] On the one hand, traditional warning signs rely solely on static graphics and text for safety reminders, lacking proactive warning capabilities. When personnel or objects approach hazardous electrical areas, they cannot issue timely alarms, making it difficult to effectively prevent safety accidents caused by negligence or accidental activation. For example, in substations and power distribution rooms, without proactive alarm devices, staff may become distracted and approach dangerous areas, posing significant safety hazards. On the other hand, in terms of structural design, the warning content display boards of existing warning signs are mostly fixed, making it difficult to change the warning information in a timely manner according to different work scenarios and changes in safety regulations. This results in the warning content being out of touch with actual needs and reduces the warning effect.

[0004] Meanwhile, warning signs often lack effective protective measures and are easily affected by rain erosion and dust accumulation when exposed to the outdoors or complex environments for extended periods. This can lead to blurred display panels, fading lettering, and even damage to the signs, shortening their lifespan. Furthermore, even when some warning signs are equipped with protective structures, they are often one-piece designs, making disassembly complex and maintenance costs high when repairs or replacements are needed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an electrical safety warning sign.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: it includes a base plate, a column welded to the top surface of the base plate, a mounting base welded to the top of the column, a warning sign welded to the top surface of the mounting base, a warning content display board detachably connected to the front side of the warning sign, a transparent protective shell detachably connected to the top of the mounting base, an alarm and a controller fixedly installed below the mounting base, and an ultrasonic sensor fixedly installed on one side of the column.

[0007] As a further description of the above technical solution: A U-shaped plate is welded to the front of the warning sign. A U-shaped slot is provided on the inner side of the U-shaped plate. The warning content display board is inserted into the U-shaped slot. Threaded rods are threaded through the front walls on both sides of the U-shaped plate. The ends of the two threaded rods near the warning content display board extend into the U-shaped slot and are rotatably connected to pressure plates. The ends of the two threaded rods away from the warning content display board extend to the outside of the U-shaped plate and are welded with rotating blocks.

[0008] As a further description of the above technical solution: Two guide rods are welded to the side of each of the two pressure plates away from the warning content display panel, and the ends of the four guide rods away from the warning content display panel slide through the front wall of the U-shaped plate and extend to the outside of the U-shaped plate.

[0009] As a further description of the above technical solution: The top surface of the mounting base has a rectangular slot, and the bottom end of the transparent protective shell is engaged in the rectangular slot. Fixing blocks are welded to the top surface of the mounting base and on both sides of the transparent protective shell. Insert rods are slidably connected to the two fixing blocks. Insert holes are opened on both sides of the transparent protective shell. The ends of the two insert rods near the transparent protective shell are respectively engaged in the two insert holes. Pull blocks are welded to the ends of the two insert rods away from the transparent protective shell. Return springs are sleeved on the outside of the two insert rods.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-4An embodiment of this utility model includes a base plate 2, a column 1 welded to the top surface of the base plate 2, a mounting base 4 welded to the top of the column 1, a warning sign 14 welded to the top surface of the mounting base 4, a warning content display board 16 detachably connected to the front side of the warning sign 14, and the warning content is placed on the front side of the warning content display board 16 (by printing, engraving, etc.). The warning content uses a simple and clear combination of icons and text to intuitively convey the type of danger (such as high voltage, do not touch) and the corresponding measures. A transparent protective shell 8 is detachably connected to the top of the mounting base 4. The transparent protective shell 8 serves to waterproof and dustproof the mounting base 4 and the warning content display board 16. An alarm 7 and a controller 6 are fixedly installed below the mounting base 4, and an ultrasonic sensor 5 is fixedly installed on one side of the column 1.

[0020] A U-shaped plate 15 is welded to the front of the warning sign 14. A U-shaped slot 20 is provided on the inner side of the U-shaped plate 15. The warning content display plate 16 is inserted into the U-shaped slot 20. Threaded rods 22 are threaded through the front walls on both sides of the U-shaped plate 15. The ends of the two threaded rods 22 near the warning content display plate 16 extend into the U-shaped slot 20 and are rotatably connected to pressure plates 21. The ends of the two threaded rods 22 away from the warning content display plate 16 extend to the outside of the U-shaped plate 15 and are welded with rotating blocks 17. The two pressure plates 21... Two guide rods 19 are welded to each side away from the warning content display panel 16. The ends of all four guide rods 19, away from the warning content display panel 16, slide through the front wall of the U-shaped plate 15 and extend to the outside of the U-shaped plate 15. The guide rods 19 serve a guiding function. By inserting the warning content display panel 16 into the U-shaped slot 20, and then rotating the two rotating blocks 17, the two rotating blocks 17 respectively drive the two threaded rods 22 to rotate, which in turn drive the two pressure plates 21 to move, thus moving the two pressure plates... 21. Pressing down on the warning content display panel 16 will fix the warning content display panel 16 in the U-shaped slot 20. The top surface of the mounting base 4 has a rectangular slot 18. The bottom end of the transparent protective shell 8 is inserted into the rectangular slot 18. Fixing blocks 9 are welded to the top surface of the mounting base 4 and on both sides of the transparent protective shell 8. Insert rods 13 are slidably connected to both fixing blocks 9. Insert holes 12 are opened on both sides of the transparent protective shell 8. The ends of the two insert rods 13 near the transparent protective shell 8 are respectively inserted into the two insert holes 12. Pull blocks 10 are welded to the ends of rods 13 away from the transparent protective shell 8. Return springs 11 are fitted on the outside of both rods 13. The two ends of the return springs 11 are welded to the side of the fixing block 9 and the side of the pull block 10, respectively. Warning signs 14 and warning content display boards 16 are located inside the transparent protective shell 8. Ultrasonic sensors 5 and alarms 7 are electrically connected to controllers 6. Multiple mounting holes 3 are provided on the base plate 2. The device can be fixed to the ground through the mounting holes 3 and bolts, which improves stability. The opening of the transparent protective shell 8 faces downward.

[0021] Working principle: The ultrasonic sensor 5 calculates the distance to the target object by emitting ultrasonic pulses and measuring the time it takes for them to reflect back. When a person or object is detected entering the preset warning range, the ultrasonic sensor 5 sends a signal to the controller 6. The controller 6 receives the signal from the ultrasonic sensor 5, processes and analyzes it. When the controller 6 determines that a person or object has entered the warning range, it sends a trigger signal to the alarm 7. The alarm 7 will emit a high-decibel alarm sound to attract people's attention and issue timely warnings. Therefore, it can effectively prevent safety accidents caused by negligence or accidental touch. The warning content is set on the front of the warning content display board 16. The warning content uses a simple and clear combination of icons and text to intuitively convey the type of danger (such as high voltage, do not touch) and the corresponding measures.

[0022] The transparent protective shell 8 serves to prevent water and dust from getting in the way of the warning content display board 16, causing the lettering to fall off, or even damaging the warning sign 14, thus extending its service life. By pulling the two pull blocks 10, the two pull blocks 10 move the two plug rods 13, causing the two plug rods 13 to move out of the two plug holes 12, which allows the transparent protective shell 8 to be lifted up and its bottom end to move out of the rectangular slot 18, thus allowing the transparent protective shell 8 to be removed from the device. When maintenance or replacement of parts is required, the disassembly process is simple and the maintenance cost is low. By rotating the two rotating blocks 17, the two rotating blocks 17 drive the two threaded rods 22 to rotate, and the two threaded rods 22 drive the two pressure plates 21 to move away from the warning content display board 16. This allows the warning content display board 16 to be moved out of the U-shaped slot 20. The warning information can be changed in a timely manner according to different work scenarios and changes in safety regulations, thus improving the warning effect.
