In this embodiment, each of the fixed cylinders 19 has a conductive ring embedded in a sidewall thereof, a conductive wire is connected between the conductive rings, the conductive ring near the pillar 1 is electrically connected to the camera 2 and the flash lamp 3, and when the conductive block 8 contacts the conductive ring, the conductive ring is electrically connected to the conductive plate 9.
One-way valves are mounted in the first communicating piece 13 and the second communicating piece 14, the one-way valve in the first communicating piece 13 only allows liquid to flow from the limiting box 11 to the second liquid storage box 15, the one-way valves in the second communicating piece 14 all allow liquid to flow from the second liquid storage box 15 to the limiting box 11, and the maximum flow allowed by the one-way valve in the first communicating piece 13 is far smaller than the maximum flow allowed by the one-way valve in the second communicating piece 14.
When the device is used, the first pressing plate 4 and the second pressing plate 16 are located on the same horizontal plane and are arranged in parallel, the distance from the starting end of the first pressing plate 4 to the tail end of the second pressing plate 16 is approximately equal to the length of a main stream non-motor vehicle body, as shown in fig. 2, the upright post 1 is far away from the first pressing plate 4, the camera 2 and the flash lamp 3 face the first pressing plate 4, the first liquid storage box 6, the limiting box 11 and the second liquid storage box 15 are filled with hydraulic oil, when no vehicle passes through, the positions of the conductive block 8, the insulating plate 10 and the sealing plate 12 are shown in fig. 2, the conductive block 8 is not connected with the conductive plate 9, and the camera 2 and the flash lamp 3 are in a power-;
when the non-motor vehicle runs in the forward direction, as shown in fig. 4, when the front wheel of the non-motor vehicle runs to the second pressure plate 16, under the action of gravity, the second pressure plate 16 compresses the first spring 5 and is close to the bottom wall of the second liquid storage box 15, hydraulic oil in the second liquid storage box 15 flows into the limiting box 11 through the second communicating member 14 and pushes the sealing plate 12 to move towards the conducting plate 9, when the sealing plate 12 moves to the leftmost end of the limiting box 11 rapidly, the insulating plate 10 fixedly connected with the sealing plate 12 is just positioned right below the fixed cylinder 19, namely, the insulating plate 10 is positioned between the conducting block 8 and the conducting plate 9;
when the non-motor vehicle continues to run until the front wheel is positioned above the first pressing plate 4, the first pressing plate 4 can also extrude the first spring 5 under the action of gravity, the first pressing plate 4 extrudes hydraulic oil in the first liquid storage box 6 to the fixed cylinder 19, so that the conductive block 8 moves downwards, but at the moment, due to the blocking effect of the insulating plate 10, the conductive block 8 cannot continuously move downwards after being abutted against the insulating plate 10, so that a circuit cannot be connected, power is supplied to the camera 2 and the flash lamp 3, the flash lamp 3 does not emit light, and the camera 2 cannot shoot the vehicle;
when the front wheel of the non-motor vehicle leaves the first pressing plate 4 and the rear wheel leaves the second pressing plate 16, the non-motor vehicle does not apply pressure to the second pressing plate 16 any more, so under the action of the spring, the second pressing plate 16 can reset upwards, the negative pressure effect is small, the hydraulic oil in the limiting box 11 flows back into the second liquid storage box 15 through the first communicating piece 13, and the sealing plate 12 drives the insulating plate 10 to reset, but because the maximum flow allowed by the one-way valve in the first communicating piece 13 is far smaller than the maximum flow allowed by the one-way valve in the second communicating piece 14, the hydraulic oil can only flow back at a slower speed, when the rear wheel of the non-motor vehicle moves onto the first pressing plate 4, the insulating plate 10 moves rightwards for a certain distance, but still is positioned between the fixed cylinder 19 and the conductive plate 9, and the conductive block 8 can also abut against the insulating plate 10;
when the rear wheel of the non-motor vehicle leaves the first pressure plate 4, the device is quickly reset under the action of the first spring 5, and it should be noted that, because the distance from the starting end of the first pressure plate 4 to the tail end of the second pressure plate 16 is approximately equal to the length of the main non-motor vehicle body, the time consumed when the rear wheel of the non-motor vehicle moves from the second pressure plate 16 to the first pressure plate 4 is very short according to the normal speed, so although the hydraulic oil can only flow back at a slow speed by the one-way valve in the first communicating member 13, the second pressure plate 16 only needs to be completely reset for several seconds, and the monitoring of the subsequent non-motor vehicle cannot be influenced;
when the vehicle runs reversely, as shown in fig. 6, the front wheel of the non-motor vehicle applies pressure to the first pressure plate 4, and similarly, the hydraulic oil in the first liquid storage box 6 pushes the conductive block 8 to move downwards until the conductive block 8 abuts against the conductive plate 9, at this time, the upper end of the conductive block 8 is also in contact with the conductive ring embedded on the side wall of the corresponding fixed cylinder 19, the conductive rings are connected through a wire, the conductive ring close to the upright post 1 is electrically connected with the camera 2 and the flash lamp 3, the municipal power grid can supply power to the camera 2 and the flash lamp 3 through the conductive plate 9, so that the flash lamp 3 flickers to remind a person who runs reversely, and the camera 2 is used for taking pictures of the vehicle running reversely, thereby facilitating subsequent public display or punishment;
when the non-motor vehicle runs to the second pressing plate 16 in the reverse direction, as shown in fig. 7, similarly, the sealing plate 12 pushes the insulating plate 10 to move leftward, but at this time, the conductive block 8 is already abutted against the conductive plate 9, the movement of the insulating plate 10 is blocked, and the flash lamp 3 is not influenced to continuously flash;
it should be noted that the non-motor vehicle is mainly an electric vehicle, and does not include a bicycle (the riding speed of the bicycle is slow, and the damage to pedestrians is small), but the self weight of the electric vehicle is large, and the self weight of the bicycle is small, so that when the bicycle passes through the first pressure plate 4, the pressure applied to the first pressure plate 4 is small, the deformation of the first spring 5 is also small, the distance of downward movement of the conductive block 8 is not enough to make the conductive block contact with the conductive plate 9, and the camera 2 and the flash lamp 3 are still in the power-off state.
Example 2
Referring to fig. 8, the present embodiment is different from embodiment 1 in that: set up the rectangular channel in the second clamp plate 16, the sealed slip of rectangular channel is provided with strikes board 17, and strikes and be connected with a plurality of second springs 18 between board 17 and the rectangular channel interior roof, strikes board 17 and can be hollow structure, increases the loudness after colliding with rattle 20, has a plurality of rattles 20 through rings movable mounting on the interior roof of rectangular channel, and the pressure valve is installed and is communicated with second stock solution box 15 through the pressure valve to the bottom of rectangular channel.
When the non-motor vehicle runs in the forward direction, the hydraulic oil in the second liquid storage box 15 flows into the limiting box 11 through the second communicating piece 14, the speed is high, the pressure of the liquid received by the pressure valve is low, and the hydraulic oil cannot enter the rectangular groove through the pressure valve;
when the non-motor vehicle runs in the reverse direction, the moving distance of the insulating plate 10 is limited, the pressure on the second pressing plate 16 is the same, the pressure of hydraulic oil in the second liquid storage box 15 on the pressure valve is increased, the hydraulic oil quickly flows into the rectangular groove and impacts the knocking plate 17, the knocking plate 17 quickly moves upwards and collides with the plurality of bells 20, and the sound generated by the vibration of the bells 20 is transmitted to the ground in a solid conduction mode to remind pedestrians in the front or at two sides of the bells to avoid the vehicle running in the reverse direction;
when the non-motor vehicle leaves the second pressure plate 16, the knocking plate 17 moves downwards under the pressure of the second spring 18 and pushes out hydraulic oil in the rectangular groove, so that the knocking plate 17 is reset.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
