  • the trapezoid refers to a shape in which the top spacing of two guide plates is greater than the bottom spacing of two guide plates and the spacing gradually decreases from top to bottom, that is, the connecting rod structure is a structure in which the spacing between two guide plates gradually decreases from top to bottom.
  • the second guide plate 7 can swing to the state of sealing the second airport 9, that is, the wind cannot circulate at the second airport 9.

  • the first guide plate 3 and the second guide plate 7 are linked through the connecting rod 4.
  • the connecting rod structure formed by the first guide plate 3, the second guide plate 7 and the connecting rod 4 is a movable structure relative to the air inlet duct. Since the connecting rod structure is a trapezoidal structure, guide channels can be formed between the first airport 1 and the first guide plate 3, and between the second airport 9 and the second guide plate 7, so as to guide the incoming wind to the air outlet 11.
  • the flow guide device can automatically adjust the included angle ⁇ between the two flow guide plates and the air inlet duct according to the vehicle speed, so as to achieve the purpose of adjusting the intake air volume.
  • the guide plate and the connecting rod 4 automatically return to the free state by their own gravity.
  • the top airport 10, the first airport 1, the second airport 9 and the air outlet 11 are in communication, and the wind enters the interior of the air inlet duct from all air inlet surfaces of the ventilation device, including the top airport 10, the first airport 1 and the second airport 9. Since the guide plate sags under the action of gravity, it plays a certain shielding effect on the airport.
  • the mounting direction of the whole ventilation device is that the front and rear air inlet surface is the same as the forward direction of the vehicle.
  • the first airport 1 is arranged on the windward side, and the first guide plate 3 is pushed by the wind thrust to push the connecting rod 4, and force is exerted on the second guide plate 7 through the connecting rod 4.
  • the second guide plate 7 swings toward the second airport 9 to seal the second airport 9, and the second airport 9 is in a sealed state and cannot ventilate.
  • the first guide plate 3 can be restricted by the connecting rod 4, so that the connecting rod structure is dynamically balanced and stationary.
  • the intake air all comes from the intake air of the first airport 1, and the second airport 9 is sealed to prevent the wind from flowing.
  • the guiding action of the first guide plate 3 can guide the wind toward the air outlet, so that the wind can flow out from the outlet.
  • the top of the air inlet duct is a negative pressure area, which can divide and outflow part of the air inlet, so that the air flow out of the air outlet 11 can be kept within a set range, which ensures that wind can always enter the air inlet duct through the airport arranged on the side of the air inlet duct at high speed.
  • the windward force Fn acts on the first guide plate 3 and is decomposed into a longitudinal force Fy and a transverse force Fx.
  • the transverse force Fx is balanced after the second guide plate 7 and the connecting rod 4 react with the first guide plate 3, and the longitudinal force Fy is dynamically balanced with the reaction force of the second guide plate 7 and the connecting rod 4 plus gravity Fg of the guide plate and the connecting rod 4.
  • the trapezoidal connecting rod structure consisting of the first guide plate, the second guide plate and the connecting rod 4 is arranged to guide the wind.
  • the connecting rod structure can adaptively adjust its own structure under the action of wind power, so as to automatically adjust the angle between the guide plate and the corresponding airport according to the change of vehicle speed, thus achieving the purpose of basically stabilizing the ventilation volume of the air outlet 11, and ensuring the ventilation volume when the vehicle runs at high speed.
  • the ventilation device is mounted at the air inlet of the ventilator in the negative pressure area of the locomotive surface, and automatically adjusts the inclination angle of the guide plate according to the running speed of the vehicle or locomotive and the air volume demand in the ventilator, which can effectively avoid too much air volume causing overflow of the ventilator, and avoid the air volume too small not meeting the ventilation volume requirements of the ventilator.
  • the first guide plate 3 can swing to the state where the first airport 1 is sealed, so that when the first airport 1 or the second airport 9 is located on the leeward side, the rail vehicle ventilation device can play the role in limiting the air volume during high-speed operation.
  • the connecting rod structure can be symmetrical in the free state, the two guide plates are the same, and the connecting position between the connecting rod 4 and the first guide plate 3 corresponds to the connecting position between the connecting rod 4 and the second guide plate 7.
  • the first airport 1 and the second airport 9 have the same structure, which is convenient for machining and can make the first airport 1 and the second airport 9 have the same capacity of limiting air volume.

Since the top airport 10, the first airport 1 and the second airport 9 may all be used as air inlets during the running of the vehicle, the mounting of the protective net 8 can reduce the entry of foreign matters into the air inlet duct and effectively play a protective role.
  • At least two connecting rods 4 may be connected between the first guide plate 3 and the second guide plate 7, and all the connecting rods 4 may be arranged in parallel. Specifically, two or other numbers of connecting rods 4 may be provided.
