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] Please see Figure 1-5 The present invention provides the following technical solution: A road construction safety warning device includes a base 1, a first warning component 2 is provided on the top of the base 1, and a second warning component 3 is provided on the top of the rear side of the first warning component 2. The first warning component 2 includes a support plate 201. A main reflective warning sign 202 is fixedly connected to the top of the support plate 201. A left reflective warning sign 203 is hinged to the left side of the main reflective warning sign 202, and a right reflective warning sign 204 is hinged to the right side of the main reflective warning sign 202. Adjusting gas rods 205 are hinged to both sides of the rear side of the main reflective warning sign 202. The output rods of the two adjusting gas rods 205 are respectively hinged to the left side of the rear side of the left reflective warning sign 203 and the right side of the rear side of the right reflective warning sign 204.

[0020] In this embodiment: by setting a base 1, a first warning component 2, and a second warning component 3, the base 1 can provide a supporting foundation for the entire device. The first warning component 2 can expand the warning angle range, thereby reducing blind spots and improving the warning effect when used on road sections such as curves or intersections. The second warning component 3 can emit warning lights and can dynamically swing, thereby further improving the warning effect.

[0021] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the second warning component 3 includes an L-shaped frame 301, which is fixedly connected to the top of the rear side of the main reflective warning sign 202. A forward and reverse motor 302 is fixedly connected to the top of the rear side of the L-shaped frame 301, and a rotating rod 303 is fixedly connected to the output shaft of the forward and reverse motor 302.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the front side of the rotating rod 303 passes through the L-shaped frame 301 and is fixedly connected to a fixing plate 304. A warning light 305 is fixedly connected to the top of the fixing plate 304.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a protective shell 306 is fitted on the surface of the forward and reverse motor 302, and the side of the protective shell 306 near the L-shaped frame 301 is fixedly connected to the L-shaped frame 301.

[0024] In this embodiment, by setting up an L-shaped frame 301, a forward and reverse motor 302, a rotating rod 303, a fixing plate 304, a warning light 305, and a protective shell 306, in use, the warning light 305 can be turned on to emit a warning light, and then the forward and reverse motor 302 can be started, causing the output shaft of the forward and reverse motor 302 to rotate in both directions, which in turn drives the rotating rod 303 to rotate in both directions. The rotating rod 303 will drive the fixing plate 304 to rotate in both directions, and the fixing plate 304 will drive the warning light 305 to rotate in both directions, thereby allowing the warning light 305 to swing dynamically, which can further improve the warning effect. The protective shell 306 can protect the forward and reverse motor 302 from dust and moisture.

[0025] Specifically, such as Figure 1 , Figure 2 As shown, an electric lifting rod 4 is fixedly connected to the top of the base 1, and the output end of the electric lifting rod 4 is fixedly connected to the bottom of the support plate 201.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a battery 5 is installed in the inner cavity of the base 1, and photovoltaic panels 6 are fixedly connected to both sides of the top of the base 1.

[0027] In this embodiment: by setting an electric lifting rod 4, the height of the support plate 201 can be adjusted, thereby adjusting the height of the first warning component 2 and the second warning component 3. By setting a storage battery 5, power can be provided to the entire device. By setting a photovoltaic panel 6, light energy can be converted into electrical energy to charge the storage battery 5.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, casters 7 are fixedly connected to the front and rear sides of the bottom of the base 1, and the casters 7 have a brake locking structure.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, mounting plates 8 are fixedly connected to the front and rear sides of both sides of the base 1, and mounting holes 9 are provided on the top of the mounting plates 8.

[0030] In this embodiment: by setting omnidirectional wheels 7, the entire device can be moved easily, and the omnidirectional wheels 7 can be locked after movement. By setting mounting plate 8 and mounting holes 9, the base 1 can be fixed to the ground with bolts or grounding rods, thereby improving the stability of the entire device and preventing it from moving due to wind.

[0031] Working principle: In use, the device can be moved to the area requiring warning via the casters 7. The base 1 can be fixed to the ground using bolts or ground anchors via the mounting plate 8 and mounting holes 9. The main reflective warning sign 202 provides a frontal warning effect. When used at bends or intersections, the two adjusting levers 205 can be activated to extend or retract, adjusting the left and right reflective warning signs 203 and 204 to the appropriate angles, thus providing a warning effect through the left and right reflective signs 203 and 204. The warning sign 204 can expand the warning angle range, reducing blind spots and improving the warning effect when used on road sections such as curves or intersections. Furthermore, by turning on the warning light 305, the warning light 305 emits a warning light, and then starting the forward and reverse motor 302, the output shaft of the forward and reverse motor 302 rotates in both directions, driving the rotating rod 303 to rotate in both directions. The rotating rod 303 drives the fixing plate 304 to rotate in both directions, and the fixing plate 304 drives the warning light 305 to rotate in both directions, thereby allowing the warning light 305 to swing dynamically, which further enhances the warning effect.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
