[0002] At present, for intersections or sections without traffic lights, pedestrians usually judge the safety of crossing the street when crossing the crosswalk. At the same time, slow-moving signs are set up at the crosswalk to remind passing vehicles to slow down and pass slowly in this area. However, when pedestrians cross the crosswalk without paying attention to passing vehicles, it is easy for drivers to fail to notice the pedestrians crossing in time and cause traffic accidents, especially in rainy fog or at night when visibility is poor.
[0003] In response to these phenomena, there is a zebra crossing laser warning column on the market. The laser warning column uses a new type of intelligent laser warning system that combines sound and light. When there are pedestrians crossing the street, it will instantly broadcast a warning voice to remind pedestrians to be careful when crossing the street. At the same time, it will project multiple beams of visible laser to the pedestrians' calves below the knees, allowing passing vehicles to detect pedestrians in time and then slow down, which can effectively improve traffic safety.
[0004] However, the existing laser warning poles are not equipped with independent power supplies, so circuits need to be laid in advance, which not only increases construction costs, but also has a long overall service life, which is not conducive to road traffic safety upgrades. Based on this, a smart pedestrian crossing warning device with a built-in solar power generation structure is provided. Utility Model Content

[0040] The first connection seat 210 and the second connection seat 212 are fixed to the bottom of the solar panel 201 along a straight line, the fixed support arm 213 is fixed to the top of the outer ring 204 and is rotatably connected to the second connection seat 212 through a rotating shaft, and the adjustment unit is movably connected to the first connection seat 210, so as to realize the installation support of the solar panel 201 above the top round seat 106;
[0041] The adjustment unit includes an oblique connecting rod 205, a rotating cylinder 206, a screw rod 207, a rotating connecting member 208, a limiting column 209, and a limiting sliding groove 211;

[0047] In this embodiment: It should be supplemented that: a mounting seat is fixedly connected to the bottom of the column 1, and the installation of the laser warning column 1 can be achieved by cooperating with the mounting seat and the bolts pre-buried in the mounting position. The installation direction of the laser warning column 1 is maintained in the following state: the laser warning column 1 is located on one side of the intersection, and the display screen 104 is facing the end away from the zebra crossing, which is used to play warning slogans so that pedestrians can intuitively see the warning slogans when approaching the zebra crossing. The laser radar detector 103 is facing the intersection. When pedestrians pass through the intersection and walk towards the zebra crossing, it can detect the pedestrians passing by. The laser generator 102 is facing the direction of the zebra crossing, so that the light beam emitted by the laser transmitter irradiates the legs of pedestrians walking on the zebra crossing, so as to achieve the effect of warning vehicles;
[0048] During actual installation, after installation according to the above requirements, the direction and angle of the solar panel 201 need to be adjusted according to the site conditions in order to obtain the best angle of sunlight exposure. The operation is as follows:
[0049] The corresponding inspection door 105 can be opened, and then the locking assembly 3 is manually released from the locking of the rotating cylinder 206, and then the rotating cylinder 206 is rotated, at which time the support unit, the adjustment unit and the solar panel 201 rotate synchronously, and then the direction of the solar panel 201 is adjusted;
[0050] After the solar panel 201 is adjusted to a suitable orientation, the locking assembly 3 is used to lock the rotating cylinder 206, and then the screw 207 is rotated. At this time, the screw 207 will move up and down along the inner wall of the rotating cylinder 206. Through the cooperation of the rotating connection 208, the limiting column 209, the first connecting seat 210, and the limiting sliding groove 211, the solar panel 201 can be rotated around the rotation point of the second connecting seat 212 and the fixed support arm 213, thereby realizing the angle adjustment of the solar panel 201;
[0051] By combining the above parts, the direction and angle of the solar panel 201 can be quickly adjusted, so that it can be installed in different environments. The solar panel 201 uses solar power to provide power for the laser transmitter group 102, the lidar detector 103, and the display screen 104, so that when the laser warning column 1 is installed, there is no need to lay additional circuits, which not only saves construction costs but also improves the overall construction efficiency.
[0052] Please refer to Figures 2-3 The locking assembly 3 includes a gear 301, a fixing seat 302, an inverted L-shaped arm 303, an arc-shaped tooth block 304, a compression spring 305, and a round block 306;
[0053] The gear 301 is fixed to the outer bottom of the rotating cylinder 206;
[0054] The fixing seat 302 is fixed to one side of the inner wall of the column 101, the vertical part of the inverted L-shaped arm 303 passes through the upper and lower ends of the fixing seat 302, and the round block 306 is fixed to the bottom end of the vertical part of the inverted L-shaped arm 303, the horizontal part of the inverted L-shaped arm 303 is fixedly connected to the arc-shaped tooth block 304, the arc-shaped tooth block 304 is engaged with the gear 301, and is used to realize the rotation locking of the rotating cylinder 206, and the arc-shaped tooth block 304 is separated from the gear 301 by moving the inverted L-shaped arm 303 upward, so as to release the locking of the rotating cylinder 206;
[0055] The compression spring 305 is sleeved on the outside of the vertical portion of the inverted L-shaped arm 303 and is distributed between the bottom of the fixing seat 302 and the top of the round block 306 to provide a downward thrust for the inverted L-shaped arm 303 .
[0056] In this embodiment, in the normal state, the arc-shaped tooth block 304 is engaged with the gear 301, so that the solar panel 201 can maintain a stable orientation (it should be noted that the threaded structure of the screw 207 and the rotating cylinder 206 can keep the angle of the solar panel 201 stable);
[0057] When the direction of the solar panel 201 needs to be adjusted, it is only necessary to lift the inverted L-shaped arm 303 upwards. The inverted L-shaped arm 303 drives the arc-shaped tooth block 304 to move upwards and separate from the gear 301, so that the rotating cylinder 206 can be unlocked. By loosening the inverted L-shaped arm 303, the inverted L-shaped arm 303 will automatically move downward and reset under the elastic force of the compression spring 305, so that the arc-shaped tooth block 304 and the gear 301 maintain a stable engagement state.
[0058] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
