Referring to fig. 1-5, an embodiment of the present utility model is provided: the warning device for road construction comprises a warning device 1, wherein a reflecting frame 2 is arranged on one side of the warning device 1; the warning device 1 comprises a base 10 and a support frame 12 arranged on the base 10, wherein an installation cavity 17 is arranged in the support frame 12, and the installation cavity 17 is sealed through a display screen 15; the two sides of the supporting frame 12 are also provided with a first mounting hole 18 and a second mounting hole 110 for mounting a laser lamp; an extension line of the central axis of the first mounting hole 18 is intersected with an extension line of the central axis of the second mounting hole 110; after the light emitted from the laser lamps in the first mounting hole 18 and the second mounting hole 110 irradiates the light reflecting frame 2, a W-shaped light is formed between the warning device 1 and the light reflecting frame 2.

In summary, the light emitted by the laser lamps in the two mounting holes, preferably the red light, is refracted back after the light irradiates the reflective frame 2, so as to form the W-shaped light, and form a red light net, such as the broken line in fig. 1, so as to remind the driver of safety.

Meanwhile, the light emitted by the laser lamp is used for covering the area between the warning device 1 and the light reflecting frame 2, and meanwhile, the light reflecting frame 2 and the warning device 1 can move mutually, so that the larger warning area can be covered under the condition that the integral structure of the equipment is not changed.

In particular, the device utilizes the light between the warning device 1 and the reflecting frame 2 to remind a driver, and compared with the prior device, the mechanical structure in a warning area is greatly reduced; the equipment stability is improved, and the equipment use cost is lower; in addition, the remote device controls the on/off of the laser lamp and changes the content displayed by the display screen 15, so that the device can also realize the function of automatic control.

On the basis of the above scheme, the contained angle between the extension line of the axis of the first mounting hole 18 and the extension line of the axis of the second mounting hole 110 is 50 degrees, when the laser lamp is assembled with the mounting hole, the laser lamp irradiates the reflecting frame 2 with the emitted light under the angle, and the W-shaped light net between the warning device 1 and the reflecting frame 2 is optimal at this time, that is, the contained angle between the emitted light and the reflected light is smaller, so as to increase the density of the light net, so that the light beams between the warning device 1 and the reflecting frame 2 are more, and the warning effect is improved.

Further, the number of the light reflecting frames 2 is two, and the two light reflecting frames 2 are symmetrically arranged at two sides of the warning device 1, in addition, the total number of the first mounting holes 18 and the second mounting holes 110 is four, and the two mounting holes are two by two and are symmetrically arranged on the side face of the supporting frame 12.

In addition, the number of the first mounting holes 18 and the second mounting holes 110 may be freely increased or decreased according to needs, for example, holes may be formed in both sides of the support frame 12 by using a drilling device in use.

Therefore, when the warning device 1 is installed in the middle of the road, the light of the laser lamp is emitted to the light reflecting frames 2 positioned at two sides of the warning device 1, so that two sides of the warning device 1 can form a W-shaped light net. Therefore, the equipment can realize large-area coverage of the warning area and simultaneously has less increment of parts. Especially, compared with the prior art, the device has the advantages that the coverage area in the warning area covered by the device is comprehensive, and the use is more convenient. For example, when the road width is 100 meters, at least two to three warning devices are needed by the existing devices, and the space occupation amount is large after the devices are completely unfolded, and the devices can also adapt to the coverage requirement of the road width by moving the light reflecting frame 2 according to the width of the road under the condition of unchanged volume.

Specifically, the light reflecting frame 2 includes a bracket 20; the bracket 20 is provided with a first mounting groove 21 for mounting the reflecting mirror, so that the reflecting mirror is convenient to mount and replace; secondly, the first mounting groove 21 can be used for protecting the reflecting mirror, so that the damage probability of the reflecting mirror is reduced; wherein, the reflecting mirror can be a mirror or other conventional reflecting devices. The support 20 is connected to the ground by a provided base plate 22.

In order to reduce the situation that rainwater and dust enter the alarm 1 to cause abnormal use of equipment, the alarm 1 further comprises a protective cover 11; wherein, the support frame 12 is installed in the protection cover 11, and the protection cover 11 is made of transparent materials.

Because the support frame 12 passes through the bottom surface of the protective cover 11 through the external thread column 16, and then is in threaded fit with the base 10, the support frame 12 and the base 10 are convenient to assemble and disassemble, and meanwhile, the protective cover 11 can be fixed on the base 10 by using the support frame 12.

In order to facilitate the penetration of the wire harness, the top surface of the support frame 12 is further provided with a through hole 19, and the through hole 19 completely penetrates through the support frame 12 and the external thread post 16, so that the wire can enter and exit the support frame 12 through the through hole 19 to supply power to the electrical components in the installation cavity 17.

On the basis of the above scheme, since the end of the protecting cover 11 far away from the base 10 is movably connected with the end cover 13, the upper end of the protecting cover 11 can be sealed by the end cover 13 to avoid the entry of dust and rainwater. While disassembly of the end cap 13 also facilitates installation of the support bracket 12 into the shield 11.

Further, the upper surface of the end cover 13 is provided with the second mounting groove 111, and the solar panel 14 is arranged in the second mounting groove 111, so that the device can also utilize solar energy, and the energy consumption of the device is reduced.
