The utility model provides a reflective film capable of being embossed to form an edge. The reflective film comprises a film body, the film body is provided with a reflective surface layer, a waterproof layer, a polystyrene foam layer and a bottom glue layer which are laminated from top to bottom; the thickness of the polystyrene foam layer is greater than that of the waterproof layer, and the thickness of the polystyrene foam layer is greater than that of the bottom glue layer; the polystyrene foam layer is configured to be capable of correspondingly forming a whole circle of edge finding structure on the peripheral side of the film body in an overflow form after the reflective film is embossed and formed; the polystyrene foam layer is arranged in the film body, the thickness of the polystyrene foam layer is larger than the thickness of the waterproof layer and the thickness of the bottom glue layer, a continuous and uniform edge finding structure can be formed on the periphery of the reflective film at a time according to the principle that polystyrene foam overflows during imprinting forming, and continuous annular protrusions are formed on the periphery of the edge finding structure, so that the reflective area is enlarged, and the reflective effect is improved. Light rays can be reflected more effectively from the side direction and different angles, and the warning effect is remarkably improved.

The application relates to a high-safety high-voltage cable applied to the technical field of cable-related technologies. When local damage occurs, water seeps at the damage point during use of the cable, which causes the corresponding cavity inside to generate gas. On one hand, the inner floating bag is inflated, gradually becomes larger, and effectively compensates for the problem of the decrease in buoyancy caused by water seepage due to the breakage; on the other hand, the gas in the cavity instantaneously increases, generates pressure on the floating block from the inside to the outside, and then makes the floating block rapidly crack. At this time, the enlarged inner floating bag leaks out, can provide buoyancy for the damage point again, is separated from the floating block, and is obviously changed in vision, so that the warning effect can be effectively ensured. Whether the cable is on the water surface or leaves the water surface after the work is completed, the obvious damage warning effect can be presented.

The application belongs to the technical field of road construction anti-collision vehicles, and particularly relates to a rear-lamp anti-collision vehicle. The rear-lamp anti-collision vehicle comprises a vehicle frame body, a vehicle compartment arranged on the vehicle frame body, a buffer pad arranged at the tail of the vehicle frame body, and a warning lamp frame assembly arranged at the tail of the vehicle compartment and close to the buffer pad. When the buffer pad is unfolded relative to the vehicle frame body, the horizontal height of the buffer pad is lower than the bottom of the warning lamp frame assembly. When the buffer pad is folded relative to the vehicle frame body, the top horizontal height of the buffer pad is lower than the top of the warning lamp frame assembly. The warning lamp frame assembly is arranged at the tail of the vehicle compartment and close to the buffer pad, so that the warning lamp frame assembly can be kept higher than the buffer pad when the buffer pad is unfolded or folded, the rear vehicle can accurately determine the safe distance from the tail of the vehicle compartment, the rear-end collision risk caused by the distance misjudgment of the driver due to the lamp frame position is avoided, the local shielding of the lamp frame by the tools or equipment on the vehicle compartment is avoided, and the warning effect of the lamp frame is ensured.

The utility model discloses a folding universal warning flagpole, which belongs to the technical field of flagpoles, and comprises an audible and visual alarm, a fixed rod, a connecting rod, an elastic piece, a movable rod and a plurality of warning assemblies, a control switch of the audible and visual alarm and the plurality of warning assemblies are arranged at the top of the movable rod, the elastic piece is arranged at the bottom of the movable rod, and the elastic piece is connected with the connecting rod. The connecting rod is installed on the top of the fixing rod which is used for being detachably connected with an oil filling pipe fixing frame. The safety of the aviation oil filling process can be improved through the multiple warning assemblies; the visual range of the multiple warning assemblies can be expanded through the movable rods, and the visibility is improved; a worker can flexibly adjust the spatial placement positions of the multiple warning assemblies, and the adaptability to the surrounding environment is improved; the movable rod can be automatically reset through the elastic piece, so that the warning effect of the warning assemblies on the movable rod is ensured to be continuous and effective, and the use is convenient.

The utility model provides a kind of warning device for coal mine, it is related to warning device technical field.A kind of warning device for coal mine, including support column, support column upper side is equipped with retraction device, retraction device is rotatably equipped with retraction shaft, retraction shaft is connected with flexible identification element, flexible identification element free end is equipped with counterweight, it is equipped with multiple intervally arranged warning sign unit element on flexible identification element, support column lower side is equipped with receiving device relative to retraction device, receiving device is rotatably equipped with receiving shaft, counterweight and receiving shaft are detachably connected.The different warning sign unit element on flexible identification element in the warning device for coal mine can be quickly replaced, so that the warning device can quickly switch warning sign, reduce the situation without identification time period;While the warning device has greater warning sign, it occupies relatively smaller storage space, ensures warning effect while reducing the hindrance of warning sign to personnel passage.

The utility model discloses a road construction safety early warning vehicle relates to road construction safety early warning technical field, including main part, the main part still includes early warning mechanism, and the bottom of main part is provided with a plurality of moving wheel, the utility model drives push plate to move down with electric telescopic link, and push plate moves down in the process of driving push rod to move down, and push rod moves down in the process of driving connecting strip synchronous down, and further make articulated guardrail expand outward to preset position, like this can accurate cover the dangerous range of construction area, let rear vehicle clear identification safety boundary, and electric telescopic link can reverse contraction, drive articulated guardrail automatic retraction, and the early warning vehicle is convenient for fastly removed to new construction position, and adapts many place operation demand, and articulated guardrail expands, and dangerous alarm flashing light passes through the light of high brightness scintillation, can remind rear vehicle in front of the construction area in several hundred meters, let the driver have enough time to slow down, change lane, and all -round improve the safety protection of construction area.

The utility model relates to warning sign device field discloses a kind of municipal sewage well lid warning signs, including first body, the left and right sides of the first body are uniformly provided with second body, the left and right sides of the first body are uniformly fixedly connected with first rod body, the left and right sides of the second body are uniformly fixedly connected with second rod body, the first rod body is connected with second rod body by clamping assembly, the bottom end inner wall of the first body and second body is uniformly fixedly connected with damping shaft, the outer wall of the damping shaft is uniformly provided with support component.In the utility model, when a certain body is damaged, the damaged body can be directly replaced, without replacing the entire body, thereby reducing the maintenance cost of the body, and the first support rod and the second support rod are supported on the ground, ensuring the stability of the first body and the second body when they are supported around the well lid, so that they cannot easily tip over, and the warning effect on pedestrians and vehicles is guaranteed.
