Please refer to fig. 1, which is a schematic diagram of each part of the automatic opening and closing device of the wind turbine tower drum platform cover plate for preventing falling object striking, the device comprises a tower drum, the tower drum is divided into a plurality of sections by a platform 7 along the height direction, each section of tower drum is internally provided with a climbing ladder 2 for climbing, the platform 7 for realizing separation of adjacent sections of tower drums is provided with a cover plate 3, the space of the adjacent sections of tower drums is communicated through the opening of the cover plate 3, and an operator can climb the climbing ladder 2 into the adjacent sections of tower drums through the space opened by the cover plate 3; the separation of adjacent section tower barrels is realized through the closing of the cover plate 3.
And a cover plate driving device is fixed on the upper surface of the platform 7 in each tower section, and the cover plate driving device is used for driving the cover plates to open and close. In this embodiment, the cover plate is a folding cover plate formed by rotationally connecting two baffle plates through hinges, and the cover plate driving device is used for driving the folding cover plate to open and close.
A controller for controlling the action of the driving device of the inner cover plate of each section of tower barrel is arranged in each section of tower barrel, and two laser sensors for sending signals to the controller are also arranged in each section of tower barrel along the height direction, wherein the lower limit laser sensor 1 is arranged below, and the upper limit laser sensor 6 is arranged above; when an operator triggers the lower limit sensor 1 and then triggers the upper limit sensor 6, the controller judges that the lower limit sensor 1 climbs upwards and controls the cover plate driving device of the upper platform to open the cover plate; otherwise, the lower cover plate is controlled to be opened by judging that the lower cover plate climbs downwards. Namely, the trigger signal of opening the cover plate is that the lower limit sensor 1 is firstly arranged, then the upper limit sensor 6 is arranged, or the upper limit sensor 6 is firstly arranged, then the lower limit sensor 1 is arranged, the climbing direction of a person is judged through the signals of the two sensors, and the corresponding cover plate is opened.
And each tower section cylinder is internally provided with an infrared sensor 8, signals of whether personnel exist in the tower section cylinder or not are sent to the controller through the infrared sensor 8, and when the personnel exist in the tower section cylinder, the personnel in the upper tower section cylinder and the lower tower section cylinder adjacent to the tower section cylinder can not open the cover plate communicated with the tower section cylinder through triggering the limit sensor. When the person in the N section wants to climb to the N+1 section, when the infrared sensor 8 in the N+1 section detects that the person exists in the section tower, the cover plate leading to the N+1 section tower is not opened under the control of the controller even if the person in the N section tower touches down the limit sensor 1 and then triggers up the limit sensor 6, until the person in the N+1 section tower climbs to the N+2 section tower, and when the infrared sensor 8 in the N+1 section tower sends a signal without the existence of the person to the controller, the cover plate leading to the N+1 section tower from the N section tower is opened under the control of the controller.

When the cover plate is opened, a person enters the next section of sleeve through the space opened by the cover plate and triggers a laser sensor signal closest to the opened cover plate, and the controller controls the cover plate to be closed. When personnel in the N-th tower section trigger a signal to open a cover plate leading to the N+1-th tower section, when personnel enter the N+1-th tower section and trigger a lower laser in the N+1-th tower section, the controller sends a signal for closing the cover plate to a cover plate control device in the N+1-th tower section. When personnel in the N-th tower barrel trigger a signal to open a cover plate leading to the N-1 th tower barrel, when personnel enter the N-1 th tower barrel and trigger an upper limit laser sensor in the N-1 th tower barrel, the controller sends a signal for closing the cover plate to a cover plate control device in the N-th tower barrel.
