The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example 1
Referring to fig. 1, a vehicle overspeed monitoring and warning device comprises a housing 1, wherein a liquid storage tank 2 and a mounting groove 3 are respectively arranged on the housing 1, a movable plate 4 is connected in the liquid storage tank 2 in a sealing and sliding manner, a movable contact 6 is connected to the lower end of the movable plate 4, a fixed contact 7 matched with the movable contact 6 is arranged on the inner bottom wall of the liquid storage tank 2, a piston plate 5 is connected in the mounting groove 3 in a sealing and sliding manner, one end of the piston plate 5 is connected with a connecting rod 9, one end of the connecting rod 9, which is far away from the piston plate 5, penetrates through the side wall of the housing 1 to extend out of the housing 1 and is connected with a wing plate 10, the wing plate 10 is in a side wing shape, the side wall of the wing plate 10, which is far away from the connecting rod 9, is arranged in an upward arched manner, a spring 11 is sleeved on the connecting rod 9, two ends of the spring 11, offer the through-hole 8 with drive area and transmission area intercommunication on the casing 1, offer communicating pipe 14 with reservoir 2 upper portion space and external intercommunication on the casing 1, when the fly leaf 4 reciprocates in reservoir 2, external gas can pass through communicating pipe 14 and advance reservoir 2 and balance reservoir 2's inside atmospheric pressure, still install controller 12 and warning light 13 on the casing 1.
In this embodiment, the driving area and the transmission area are both filled with hydraulic oil, and the hydraulic oil is 46 # turbine oil, which has a non-conductive characteristic, so that when the moving contact 6 is not in contact with the stationary contact 7, the hydraulic oil can electrically block the moving contact and the stationary contact; the controller 12 is provided with a signal receiver and a signal transmitter respectively, and the input end of the signal transmitter is electrically connected with the moving contact 6 and the static contact 7 respectively through a conducting wire, that is, when the moving contact 6 is electrically conducted with the static contact 7, the signal transmitter on the controller 12 is started and can immediately transmit a signal of vehicle overspeed to a signal receiver in the controller 12 on a subsequent device.
When the device is used in the embodiment, a plurality of devices are sequentially placed beside a road, the convex side of the wing plate 10 faces the road, when an overspeed vehicle passes through the equipment, the vehicle can drive the gas near the equipment to flow at high speed in the vehicle running direction, and the Bernoulli principle shows that, the pressure at the two side walls of the wing plate 10 is different in the flowing air, the generated pressure difference can drive the wing plate 10 to move towards the direction close to the vehicle, as the space in the driving area becomes larger along with the movement of the wing plate 10, the spring 11 is compressed, the hydraulic oil in the transmission area flows into the driving area through the through hole 8, the movable plate 4 moves downwards, so that the movable contact 6 is contacted with the fixed contact 7, the signal transmitter on the controller 12 is started and transmits the signal of vehicle overspeed to the signal receiver on the subsequent controller 12, the subsequent controller 12 controls the corresponding warning lamp 13 to work to warn the overspeed vehicle;
when a vehicle running normally passes through the equipment, because the speed of the vehicle running normally is smaller than that of an overspeed vehicle and the impact force of airflow brought by the vehicle is smaller, the moving distance of the wing plate 10 is smaller, the space change of a driving area is smaller, the descending distance of the movable plate 4 is smaller, the movable contact 6 on the movable plate 4 cannot be electrically conducted with the static contact 7, and a signal emitter on the controller 12 cannot emit signals;
when the vehicle leaves the device, the piston plate 5 is reset under the elastic force of the spring 11, the hydraulic oil in the driving area flows back to the transmission area through the through hole 8, and the movable plate 4 and the wing plate 10 are reset simultaneously, so that the subsequent vehicle can be continuously detected and warned.
Example 2
The present embodiment differs from embodiment 1 in that: an elastic air bag 15 is arranged between the upper end face of the movable plate 4 and the top wall in the liquid storage tank 2, the upper end and the lower end of the elastic air bag 15 are respectively and fixedly connected to the top wall in the liquid storage tank 2 and the upper end face of the movable plate 4, a plurality of gas ejecting pipes 17 are evenly arranged in the mounting groove 3, the output ends of the plurality of gas ejecting pipes 17 are respectively opposite to one side of the piston plate 5 away from the driving area, the input ends of the plurality of gas ejecting pipes 17 are communicated with the elastic air bag 15 through exhaust pipes 16, the diameter of each gas ejecting pipe 17 is far smaller than that of the exhaust pipe 16, so that the gas ejected by the gas ejecting pipes 17 has larger kinetic energy, a plurality of grooves corresponding to the gas ejecting pipes 17 are evenly arranged on one side face of the piston plate 5 opposite to the gas ejecting pipes 17, so that the impact force of the gas ejected by the gas ejecting pipes 17 on the piston plate 5 is more concentrated, the communicating pipe 14 communicates the, the first one-way valve only allows the outside air to enter the elastic air bag 15 through the communicating pipe 14, and the second one-way valve only allows the air in the elastic air bag 15 to enter the air injection pipe 17 through the exhaust pipe 16.
When the embodiment is used, when a vehicle moves through the driving wing plate 10, hydraulic oil in the transmission area enters the driving area through the through hole 8, the movable plate 4 moves downwards along with the hydraulic oil, the elastic air bag 15 is stretched, external gas enters the elastic air bag 15 through the communicating pipe 14, when the vehicle drives away from the device, the movable plate 4 moves upwards to reset, the elastic air bag 15 is compressed, gas in the elastic air bag enters the gas ejecting pipe 17 through the exhaust pipe 16 and is ejected to the upper groove of the piston plate 5 through the gas ejecting port of the gas ejecting pipe 17, the reset of the piston plate 5 is accelerated, resonance caused by the spring 11 is buffered and eliminated, and therefore when the vehicle flow on the road is large, the device can also reset in time after monitoring and warning each vehicle, and the accuracy of a monitoring result is guaranteed.
