The first embodiment is as follows:
as shown in fig. 1 to 4, an intelligent transportation device includes a pair of abdicating grooves 2 respectively fixed and buried at two ends of a zebra crossing, wherein the upper ends of the abdicating grooves 2 are open and the upper end faces are flush with the road surface.
As shown in fig. 2 and 3, each of the two side bottom walls of the abdicating groove 2 is fixedly connected with an electric telescopic rod 1, the abdicating groove 2 is internally provided with a warning belt 3 in a folding manner, and the lower end surface of the warning belt 3 is fixedly connected with the inner wall of the abdicating groove 2.
As shown in fig. 2, the warning belt 3 is provided with a row of mounting holes 13 penetrating through the two sides of the electric telescopic rod 1 along the height direction thereof at intervals, the mounting holes 13 are internally and fixedly embedded with mounting rings 4, the mounting rings 4 are sequentially sleeved on the electric telescopic rod 1 corresponding thereto in a sliding manner, and the mounting rings 4 at the top are fixedly connected with the top end of the electric telescopic rod 1.
As shown in fig. 2, the side wall of the electric telescopic rod 1 is fixedly connected with a transmitter 5 for receiving traffic signal lamp information and sending a signal, the side wall of the electric telescopic rod 1 is fixedly connected with a receiver 6, the receiver 6 is used for receiving the signal sent by the transmitter 5, and the receiver 6 is fixedly connected with a controller 7 for controlling the electric telescopic rod 1 to ascend and descend.
When the traffic equipment is applied, the receiver 6 receives a forbidding signal from the traffic signal lamp and transmits the signal to the receiver 6, so that the controller 7 on the receiver 6 drives the top end of the electric telescopic rod 1 to drive the warning belt 3 to move upwards. When the two electric telescopic rods 1 move upwards to the maximum stroke, the warning belt 3 is in a stretching state and intercepts pedestrians on two sides of the zebra crossing through the warning belt 3, so that the pedestrians are prevented from crossing the road at will.
Receive the signal of letting pass from the traffic signal lamp and give receiver 6 with this signal transmission when receiver 6 for the top of controller 7 drive electric telescopic handle 1 on the receiver 6 drives warning area 3 downstream, and when two electric telescopic handle 1 reset, warning area 3 fall back to the inslot of stepping down 2, make the pedestrian normally current.
Utilize traffic signal lamp control electric telescopic handle 1 to drive warning area 3 and expand and fold to realize the interception and the clearance to the pedestrian, play the effect of assisting traffic management.
Because the row of mounting rings 4 are sequentially sleeved on the corresponding electric telescopic rods 1 in a sliding manner, the movement path of the warning belt 3 can be well limited and guided. Because the unable upset of collar 4 is to vertical state, when warning area 3 downstream, warning area 3 can be folded fast and fall to the inslot 2 of stepping down under the action of gravity of collar 4 to improve traffic equipment's practicality.
As shown in fig. 2 and 3, a baffle 8 is embedded in the upper end of the abdicating groove 2, the side wall of one side of the baffle 8 is hinged to the inner wall of the upper end of the abdicating groove 2, a plurality of torsion springs 9 are arranged between the lower end surface of the baffle 8 and the inner wall of the upper end of the abdicating groove 2 at intervals, and a circle of limiting ring 10 used for abutting against the lower end surface of the baffle 8 is arranged on the inner wall of the upper end of the abdicating groove 2. A plurality of water seepage holes 14 communicated with a sewer are penetrated through the bottom wall of the abdicating groove 2.
When using above-mentioned traffic facilities, the top through electric telescopic handle 1 drives warning area 3 upward movement, conflicts 8 lower terminal surfaces of baffle when electric telescopic handle 1's top for baffle 8 upwards overturns around the pin joint, and torsional spring 9 is in compression state this moment.
When the top of electric telescopic handle 1 drove warning area 3 downstream, baffle 8 overturns downwards round the pin joint under the spring action of torsional spring 9, when electric telescopic handle 1 and warning area 3 fall back to the groove of stepping down 2 in, the lower terminal surface of baffle 8 contradicts the up end of spacing ring 10 to realize the reposition of baffle 8 and to step down 2 open-ended closing caps in the groove.
Utilize baffle 8 to carry out the closing cap to the groove of stepping down 2, can prevent effectively that debris on the road surface from falling into the groove of stepping down 2 in, improve the smoothness nature of transportation equipment during operation.
Through setting up infiltration hole 14 for the rainwater that enters into in the groove of stepping down 2 can be quick arrange to the sewer in through infiltration hole 14, prevent to step down the interior ponding phenomenon that appears of groove 2, guarantee traffic equipment's normal work.
As shown in fig. 4, a plurality of vent holes 15 are perforated in the surface of the warning tape 3. A steel ring 11 is embedded in each ventilation hole 15. The warning tape 3 is provided with a plurality of fluorescent sheets 12 on the surface.
Through setting up ventilation hole 15, when warning area 3 is in the state of stretching, the air current can be discharged through ventilation hole 15, effectively reduces the resistance that warning area 3 received in the air current, avoids warning area 3 to rock to improve traffic equipment's stability in use.
The steel ring 11 can improve the overall structure intensity of the warning tape 3, can increase the gravity of the warning tape 3, and avoids the warning tape 3 from swaying with the wind, thereby further improving the use stability of the traffic equipment.
The feature that the fluorescent sheet 12 can emit light at night is utilized, so that the night use capability of the traffic equipment is increased, and the practicability of the traffic equipment is further improved.
Further, the outer surface of the baffle 8 is painted with white paint as a component of the floor zebra crossing.
Example two:
the technical solution of the first embodiment needs to be used in an intersection with a traffic light, but cannot function in an intersection without a traffic light. To overcome this problem, the present application improves herein.
The difference from the first embodiment is that:
the generator 5 is preferably a pressure sensor wirelessly connected to a receiver 6, which is arranged on the zebra crossing.
Specifically, the method comprises the following steps: the lateral wall fixedly connected with receiver 6 of electric telescopic handle 1, receiver 6 are used for receiving the signal that emitter 5 sent, and fixedly connected with is used for controlling controller 7 that electric telescopic handle 1 goes up and down on receiver 6.
In this embodiment, when an external pressure acts on the zebra crossing, so that the pressure sensor on the zebra crossing senses the external pressure, the electric telescopic rod 1 is driven by the receiver 6 and the controller 7.
Further, when the pressure sensor detects that the pressure of the external pressure to the zebra crossing is more than 105pa, the pressure sensor transmits a signal to the controller 7, and the controller 7 drives the electric telescopic rod 1 to extend.
In practical use, if the pressure of the external pressure acting on the zebra crossing is less than 105pa, the electric telescopic rod 1 is in a retraction state.
Specifically, the following are mentioned: the national bureau of metrology JJG1008-87 Specification "nomenclature and definition of pressure measurement" explicitly states that: pressure (Pressure) is a distributed force acting perpendicularly on a unit area, i.e. for engineering applications of Pressure sensors, it can be used to check the distributed force per unit area, i.e. the Pressure.
The specific embodiments are only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications without inventive contribution to the present embodiments as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
