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 shall fall within the scope of protection of the present invention.

[0026] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] See also Figures 1-4 The utility model provides a tunnel traffic safety reminder alarm device, comprising: a displacement mechanism 1, a support mechanism 2 connected to the displacement mechanism 1, and a display mechanism 3 connected to the support mechanism 2.

[0028] In some embodiments, the displacement mechanism 1 can be connected to the top of the tunnel or the gantry, so that the tunnel traffic safety reminder alarm device can be suspended above the lane. In some embodiments, the displacement mechanism 1 is arranged along the width direction of the lane. The displacement mechanism 1 is used to drive the tunnel traffic safety reminder alarm device to move, thereby moving the display mechanism 3 above the target lane, thereby realizing lane-level safety reminder.

[0029] Furthermore, the displacement mechanism 1 includes: a suspension member 11, a track frame 12 connected to the suspension member 11, and a trolley 13 connected to the track frame 12; in some embodiments, the suspension member 11 is a connecting component that connects the tunnel traffic safety reminder alarm device to a fixed building, and is used to suspend the track frame 12 horizontally below.

[0030] In some embodiments, the track frame 12 is a square frame structure, on which are provided two sets of parallel track grooves 121, and the track grooves 121 are slidingly connected to the trolley 13. On the one hand, the track grooves 121 are used to guide the trolley 13 to move in a predetermined direction, and on the other hand, the trolley 13 can also be used for limiting.

[0031] Furthermore, the trolley 13 includes: a pulley 131 adapted to the track groove 121, a connecting shaft 132 connected to the pulley 131, a first transmission gear 133 provided on the connecting shaft 132, a second transmission gear 134 meshed with the first transmission gear 133, a first motor 135 connected to the second transmission gear 134, and a fixing part 136 connected to the connecting shaft 132.

[0032] In some embodiments, the first motor 135 can convert electrical energy into mechanical energy based on the principle of electromagnetic induction and transmit it to subsequent components or actuators. The first motor 135 then drives the connecting shaft 132 and the pulley 131 through the second transmission gear 134 and the first transmission gear 133 to rotate, thereby achieving the technical effect of moving the transmission trolley 13 on the track frame 12. In some embodiments, the movement of the trolley 13 can enable the tunnel traffic safety warning alarm device to move laterally within the tunnel.
