This application can improve the warning device's ability to provide voice information to oncoming vehicles or pedestrians in certain scenarios, enabling them to better understand the road conditions ahead and further improve road traffic safety.

[0004] The technical solution has the following problems:

[0005] After prolonged use, dust may accumulate on the surface of the warning box, obscuring the warning information and affecting its effectiveness. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a road transport warning device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A road transport warning device includes a base with self-braking casters at the bottom. An adjusting cylinder is fixedly connected to the top of the base, and an adjusting mechanism is located inside the adjusting cylinder. An adjusting column is mounted on the adjusting mechanism, and a warning box is fixedly connected to the top of the adjusting column. A warning sign is located on the front of the warning box, and a voice prompt box is bolted to the top of the warning box. The voice prompt box contains a speaker controlled by a controller, and a sensor probe electrically connected to the controller is located on one side of the voice prompt box.

[0009] A cleaning system is installed on the warning box to clean the warning signs.

[0010] In one possible design, the adjusting mechanism includes a connecting shaft and a bidirectional lead screw. The connecting shaft is rotatably mounted on the adjusting cylinder. The bottom end of the bidirectional lead screw is rotatably connected to the bottom inner wall of the adjusting cylinder. One end of the connecting shaft extends into the adjusting cylinder. Both the connecting shaft and the bidirectional lead screw are fixedly connected to bevel gears, which mesh with each other. The adjusting column has a through hole, and a first lead screw nut is fixedly connected inside the through hole. The top end of the bidirectional lead screw extends into the through hole and is threadedly connected to the first lead screw nut. Slider blocks are fixedly connected to both sides of the adjusting column. The inner wall of the adjusting cylinder has a groove adapted to the slider, and the slider is slidably connected in the groove. A fastening nut is threadedly connected to the connecting shaft.

[0011] In one possible design, the cleaning mechanism includes a water storage tank, a rain collection hopper, a water pump, and a spray pipe. The water storage tank is fixedly connected to the top of the warning box and has an inlet pipe. The rain collection hopper is connected to the water storage tank. The water pump is fixedly connected to the top of the warning box, with its input end extending into the water storage tank and its output end connected to the spray pipe. The spray pipe is fixedly connected to the water storage tank and has multiple nozzles.

[0012] In one possible design, a movable disc is threadedly connected to the bidirectional lead screw, and a second lead screw nut is embedded in the movable disc. The bidirectional lead screw is threadedly connected to the second lead screw nut. Two movable columns are fixedly connected to the bottom of the movable disc. The bottom ends of the two movable columns pass through the adjusting cylinder and the base and are fixedly connected to a stabilizing plate. The bottom of the stabilizing plate is provided with an anti-slip pad. Movable blocks are fixedly connected to both sides of the movable disc. A movable groove adapted to the movable block is opened on the inner wall of the adjusting cylinder, and the movable block is slidably connected in the movable groove.

[0013] In one possible design, the top of the rain hopper is bolted with a filter screen for filtering impurities.

[0014] In one possible design, a waterproof cover is fixedly connected to one side of the water storage tank.

[0015] In this application, the base is first moved to a suitable position, and then the brakes on the casters are engaged. This is followed by rotating the connecting shaft, which rotates the bidirectional lead screw via two bevel gears. The rotation of the bidirectional lead screw causes the first lead screw nut and the second lead screw nut to move in opposite directions. The second lead screw nut causes the moving plate to move the two moving columns downward, which in turn causes the stabilizing plate to move downward. When the stabilizing plate is in contact with the ground, the rotation stops. At this point, the first lead screw nut causes the adjusting column to move upward a certain height, thereby moving the warning box to a certain height.

[0016] The system uses sensors on the voice prompt box to detect vehicles and provide voice alerts to passing vehicles. Warning signs provide visual warnings. When the warning signs need cleaning, a water pump can be activated to draw water from the water tank and spray it onto the warning signs through nozzles on the spray pipe, thus cleaning their surfaces and making them cleaner.

[0017] In this invention, the use of clear warning signs and voice prompts can more effectively attract the attention of passing vehicles and pedestrians, promptly reminding them to pay attention to safety, thereby reducing the risk of traffic accidents.

[0018] The cleaning system ensures the cleanliness of the warning signs, keeping them clearly visible even in inclement weather or after prolonged use, further enhancing their warning effectiveness.

[0019] In this invention, the combined use of a rainwater collection hopper and a filter screen enables the device to collect and utilize natural water sources such as rainwater for cleaning, thereby reducing the waste of water resources. Attached Figure Description
