Description

Technical Field

[0001] The utility model relates to the technical field of warning signs, and in particular to a warning device for engineering supervision. Background Art

[0002] Engineering supervisors use warning devices and warning signs at construction sites to ensure the safety of workers and passers-by. The text and graphic designs on the warning signs will alert people to potential dangers. At night or in low-light conditions, the text and patterns on the warning signs will use reflective materials or install reflective strips around the signs. These reflective materials can emit light by reflecting surrounding light sources at night or in low-light environments, making the content of the warning sign more obvious and easy to see, thereby effectively improving the visibility of the warning and reducing the risk of accidents at night or in poor visibility. However, in the absence of lights at night, the reflective material will not work, and the visibility of the warning sign will be greatly reduced, which may easily lead to pedestrians failing to perceive the warning information in time, thereby causing danger. Therefore, a warning device for engineering supervision is needed. Utility Model Content

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the absence of lights at night, the reflective material will not work, and the visibility of the warning sign will be greatly reduced, which may cause pedestrians to fail to notice the warning information in time, thus causing danger. Figure 1-Figure 4 This embodiment provides a warning device for engineering supervision, including a box body 1.

[0021] refer to Figure 1 As shown, in the absence of lights at night, the reflective material of existing methods is ineffective, significantly reducing the visibility of warning signs. This can easily lead to pedestrians failing to perceive the warning message in a timely manner, potentially causing danger. To enhance the visual multiple warning effects, the following configuration is specifically implemented: a light-emitting sign 3 and a matte sign 4 are installed within the housing 1. The matte sign 4 does not rely on electricity or special light sources, relying solely on the reflective material to enhance the warning effect. In this case, the reflective material can effectively improve the visibility of the warning sign during the day, especially in sunny conditions. The use of light-emitting sign 3 at night (such as a light-emitting sign with an internal wick) can provide clear visual effects through its own light in the absence of external light sources. This is crucial for ensuring safety warnings in low-light environments, especially at night or in conditions of low visibility. By alternating between the matte sign 4 and light-emitting sign 3, the respective characteristics of each can be fully utilized to ensure optimal warning effects under different lighting conditions. The matte sign 4, with its good reflectivity during the day, will not be ineffective due to insufficient external light sources. At night, the light-emitting sign 3 provides additional visual warnings, ensuring all-weather safety. During the day, ultraviolet radiation can accelerate the aging of some luminescent materials and even affect their luminous effect. Placing the luminous sign 3 inside the box 1 during the day can prevent premature damage caused by long-term exposure to the sun. The bottom end of the matte sign 4 is hinged to the interior of the box 1. A storage box 2 is slidably mounted within the box 1. A track block is fixed to the bottom of the storage box 2. The inner wall of the box 1 is provided with a slide rail, and the track block slides back and forth along the length of the rail. The luminous sign 3 is fixed to the side of the storage box 2 adjacent to the matte sign 4.

[0022] refer to Figure 2-Figure 4As shown, a replacement mechanism 5 is provided on the top of the box body 1, and the replacement mechanism 5 includes a power plate 51 fixed on the top of the storage box 2. The outer structure of the power plate 51 is in the shape of an n. Two rectangular grooves for sliding the power plate 51 are provided on the top of the box body 1, as well as two connecting half wheels 52 fixed on one side of the storage box 2. A connecting rod 1 53 is rotated on the inner wall of one connecting half wheel 52, and a movable groove 54 running through the left and right surfaces thereof is provided on the inner wall of the connecting rod 1 53. A connecting rod 2 55 is rotated on the inner wall of the other connecting half wheel 52, and a sliding rod 56 arranged inside the movable groove 54 is fixed on one side of the bottom end of the connecting rod 2 55. A connecting rod 3 57 is rotated on one side of the matte sign 4, and one end of the connecting rod 3 57 adjacent to the connecting rod 2 55 is connected to the matte sign 4. It is rotatably connected. When the luminous sign 3 is needed at night, the staff manually pushes the force plate 51 to move the storage box 2. The movement of the storage box 2 pushes the luminous sign 3 to resist the matte sign 4, causing the matte sign 4 to rotate left with its bottom end as the center of rotation and gradually open the box body 1. During this process, the connecting rod 3 57 moves to push the connecting rod 2 55 to rotate right, thereby causing the slide bar 56 to slide in the moving groove 54, and then causing the connecting rod 1 53 to rotate left. Until the matte sign 4 rotates 90 degrees to be flush, the luminous sign 3 completely protrudes from the outside of the box body 1 to replace the warning of the matte sign 4. After daybreak, the staff pushes the force plate 51 in the opposite direction, and reverses the above principle to retract the luminous sign 3 into the box body 1, and the matte sign 4 returns to its original position to replace the warning of the luminous sign 3.

[0023] refer to Figure 2 As shown, the top of the box body 1 is provided with an energy-saving mechanism 6, which includes a photovoltaic panel 61 fixed to the top of the box body 1. The interior of the storage box 2 is provided with a battery 62 electrically connected to the photovoltaic panel 61. The top of the photovoltaic panel 61 is flush with the top of the box body 1, and the distance between the top of the photovoltaic panel 61 and the inner wall of the power plate 51 is 0.1 cm to 0.5 cm. During the day, the photovoltaic panel 61 uses sunlight to convert light energy into electrical energy and stores the generated direct current in the battery 62 through the circuit. At night, the electricity in the battery 62 will power the luminous sign 3 to light it up, providing the required warning effect. This not only saves the cost of traditional power supply, but also ensures that the warning function continues in the absence of an external power source.

[0024] refer to Figure 4As shown, a telescopic protective cover 7 is provided on the top of the housing 1, with its ends fixed to the housing 1 and the power plate 51, respectively. At night, when the propulsion plate 51 causes the luminous sign 3 to replace the dull sign 4, the telescopic protective cover 7 is stretched and expanded in sync with the movement of the power plate 51, thereby providing nighttime protection on top of the photovoltaic panel 61 and preventing dew from accumulating there. This expansion of the telescopic protective cover 7 effectively prevents dew from directly contacting the photovoltaic panel 61, particularly in humid conditions or with large temperature fluctuations, reducing damage to the photovoltaic panel 61 caused by dew accumulation or frost. During the day, when the reverse propulsion plate 51 causes the dull sign 4 to replace the luminous sign 3, the telescopic protective cover 7 is compressed and restored in sync with the movement of the power plate 51, eliminating any obstruction or protection of the photovoltaic panel 61 and allowing it to operate normally.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
