When the air conditioner is in actual use, the air volume adjusting door device is connected with an air outlet pipe of a fan by using the connecting flange 2, the connecting cover 3 at the other end is placed outdoors, when the outdoor wind strength is higher in grade, the air volume adjusting door device can be blown onto the windward mechanism 8, the windward mechanism 8 can rotate (swing) in a small range upwards or downwards along the connecting cover 3 from the initial end under the guidance of the arc-shaped channel 7, the windward mechanism 8 can transmit rotary power to the transmission mechanism 9 no matter rotates upwards or downwards, the transmission mechanism 9 transmits the rotary power to each wind adjusting plate 6, the wind adjusting plates 6 are mutually closed from an open state, the ventilation pipe 1 is changed from normal exhaust to exhaust termination, and meanwhile, the phenomenon that outdoor high-pressure gas reversely blows into the ventilation pipe 1 and enters the fan along the ventilation pipe 1 to generate resistance to the normal rotation of blades to cause the rotation overload of the blades and high-temperature heating is avoided, and the following steps of: the pressure of the outdoor wind mentioned in the invention is satisfied that the windward mechanism 8 can be driven to rotate up and down, but not a specific pressure value, the setting purpose is only to protect the fan in the ventilation pipe 1, the outdoor wind power level can gradually decline, and the outdoor wind power level can be changed in various ways under the same wind power level, in a word, when the pressure value of the outdoor wind power can blow the windward mechanism 8 to rotate up and down, the windward mechanism 8 can drive the transmission mechanism 9 to close the wind adjusting plates 6, otherwise, when the pressure value of the outdoor wind power is not enough to blow the windward mechanism 8 to rotate up and down, the windward mechanism 8 can be reset reversely, so that all the wind adjusting plates 6 are forced to be opened to a normal use state in a reverse driving mode, and the ventilation pipe 1 is ventilated normally.
The above is only a description through each assembly mechanism, and the following is a developed description of the main body constitution of each mechanism: the windward mechanism 8 comprises a guide rod 10 fixed in the connecting cover 3, a gas collection assembly 11 sliding on the guide rod 10, and a slide rod 12, one end of which is connected to the gas collection assembly 11 and the other end of which is in sliding fit with the connecting cover 3 through an arc-shaped channel 7, the gas collection assembly 11 comprises a gas collection cover 14 extending outside the connecting cover 3 and used for receiving outdoor gas, and a gas collection seat 13 which is positioned at the inner end of the gas collection cover 14 and slides on the guide rod 10 to collect the received outdoor gas in a concentrated manner, wherein the outdoor gas is collected into the gas collection seat 13 continuously, so that the pressure in the gas collection seat 13 is gradually increased, and the gas collection assembly 11 is rotated downwards along the guide rod 10 by utilizing higher pressure. That is, when the outdoor wind pressure value can blow the windward mechanism 8, substantially the wind enters the gas collecting seat 13 from the gas collecting hood 14, and is gradually collected in the gas collecting seat 13, and then is continuously collected from the gas collecting seat 13 to the tapered cavity 23 in the tapered seat 22 at the bottom, so that the air pressure in the tapered cavity 23 gradually increases, because the tapered seat 22 is located at the bottom of the gas collecting seat 13 and extends downwards, an eccentric structure is equivalently arranged on the gas collecting seat 13, so that the gas collecting seat 13 is forced to rotate downwards with the whole windward mechanism 8 under the action of the air pressure, and the windward mechanism 8 realizes rolling guidance by using the universal ball 20, the tail end of the sliding rod 12 of which rolls in the arc-shaped channel 7, while rotating downwards, so as to ensure that the windward mechanism 8 can flexibly rotate when being impacted by outdoor strong wind. In addition to the above-mentioned development of the windward mechanism 8, which makes the windward mechanism 8 reasonably complete a small-amplitude rotation when the windward mechanism 8 is exposed to strong outdoor wind, the following descriptions are provided for the transmission mechanism 9 and how the transmission mechanism 9 and the windward mechanism 8 realize transmission: the transmission mechanism 9 comprises a second bearing 15 embedded in the sleeve 4, a rotating shaft 16 mounted on the second bearing 15, and a connecting rod 17 connected between the rotating shaft 16 and the air collecting assembly 11 (substantially connected to the air collecting base 13), the air collecting assembly 11 (i.e. the windward mechanism 8) rotates downward along the guide rod 10 and also drives the connecting rod 17 to rotate downward, and at the same time, the connecting rod 17 drives the rotating shaft 16 to rotate, the inner end of the rotating shaft 16 extends into the sleeve 4 and is provided with a bevel gear disc 18 capable of rotating with the rotating shaft in the sleeve 4, one end of the air adjusting plate 6 connected to the first bearing 5 penetrates into the sleeve 4 and is provided with bevel gears 19 distributed on the periphery of the bevel gear disc 18, and all the bevel gears 19 are meshed with the tapered tooth surfaces of the bevel gears 19 together, so that the bevel gear disc 18 rotates and also drives all the bevel gears 19 to rotate simultaneously, and finally all the air adjusting plates 6 rotate from being opened to being closed. In summary, the windward mechanism 8 and the transmission mechanism 9 are arranged to enable outdoor high-level wind to act on the windward mechanism 8 temporarily, then enter the windward mechanism 8 to form impact air pressure, and by utilizing the structural characteristics that the windward mechanism 8 slides on the guide rod 10, the windward mechanism 8 rotates in a small amplitude (swings in a small amplitude) under the guidance of the guide rod 10, the rotary power is transmitted into the transmission mechanism 9 under the driving of the connecting rod 17, and then all the wind adjusting plates 6 are closed rapidly under the transmission of a series of tooth surfaces on the transmission mechanism 9. Particularly, the air collecting assembly 11 in the windward mechanism 8 is supplied with air by the air collecting hood 14, and air pressure is formed by rapidly collecting wind power at the air collecting seat 13 and the conical seat 22, when the air pressure is greater than the elastic supporting force of the spring 24 to the conical seat 22, the conical seat 22 drives the whole windward mechanism 8 to rotate downwards, and when the air pressure is less than the elastic supporting force of the spring 24 to the conical seat 22, the conical seat 22 drives the whole windward mechanism 8 to reset upwards, and the size of the air pressure is just the size of the wind power from the outdoors.
As further preferred: when the two adjacent wind adjusting plates 6 rotate to tend to be closed, a gap which enables the two adjacent wind adjusting plates 6 to be separated from each other is substantially reserved between the two adjacent wind adjusting plates 6, but the two adjacent wind adjusting plates are not completely closed, only the outdoor high-intensity airflow with a large area is prevented from acting on the fan along the ventilation pipe 1, a certain gap is reserved between the two wind adjusting plates 6 after the wind adjusting plates 6 are closed, ventilation can still be achieved, the fan is prevented from rotating in a completely closed state to generate negative pressure in the cabin, as is well known, the outdoor high-level wind is not always continuous, and the same level of wind changes within a few seconds, and when the wind rises to be larger than the elastic supporting force of the spring 24 on the conical seat 22 within the few seconds, the airflow entering the gas collection assembly 11 is increased, the conical seat 22 drives the whole windward mechanism 8 to rotate downwards or upwards, and all the wind adjusting plates 6 are rapidly closed under the driving of the transmission mechanism 9 (the rotation of the ventilation pipe 16 drives the conical tooth disc 18 to rotate, and the conical tooth disc 18 drives all the bevel gears 19 to drive all the wind adjusting plates 6 to rotate), and the wind adjusting plates 1 are relatively closed. On the contrary, when the wind power drops to be less than the elastic supporting force of the spring 24 to the conical seat 22 within a few seconds, the airflow entering the gas collecting assembly 11 is reduced, the conical seat 22 drives the whole windward mechanism 8 to return upwards, all the wind adjusting plates 6 are rapidly opened under the driving of the transmission mechanism 9, and the ventilation pipe 1 is relatively opened to discharge air normally.
In order to improve the working efficiency, outdoor high-grade wind can be received by the windward mechanisms 8 when being blown from two directions, so that the windward mechanisms 8 are arranged in two places and are symmetrically arranged, after the wind adjusting device is actually installed, the two windward mechanisms 8 respectively correspond to a north side and a south side, and the high-grade wind can be received and utilized when being a south wind or a north wind (not completely a true south, a true north and a true south), similarly, the two connecting rods 17 are also symmetrically distributed and are jointly connected to the same rotating shaft 16, namely, the air collecting seats 13 in the two windward mechanisms 8 are connected to the rotating shaft 16 through the two connecting rods 17, when the outdoor wind comes from the north side, the outdoor wind enters the windward mechanisms 8 from the north side, and when the wind power collected by the air collecting ventilation pipe assembly 11 in the windward mechanisms 8 is greater than the elastic supporting force of the springs 24 on the conical seats 22, the north side wind collecting seats force the windward mechanisms 8 to rotate (swing) downwards along the guide rods 10, and the conical disks 18 are driven to rotate and drive the bevel gears 6 to rotate. Similarly, when the outdoor wind comes from north, the same principle is used to force the windward mechanism 8 in south to rotate (swing) downwards along the guide rod 10, and all the wind adjusting plates 6 can be closed in the manner of the same principle, so that the arrangement of the two groups of windward mechanisms 8 and the two connecting rods 17 is more reasonable in practical use, and the two groups of windward mechanisms 8 and the two connecting rods 17 are simultaneously connected to the same rotating shaft 16, and the opening and closing actions can be completed when the windward mechanisms 8 in any direction receive wind power, so that the installation position of the rotating shaft 16, the distribution manner of the bevel gear disc 18 and the bevel gear 19 are more reasonable compared with the arrangement of the two connecting rods 17 and the two windward mechanisms 8. And the outer ends of the gas-collecting hoods 14 of the two windward mechanisms 8 are respectively provided with oblique openings 21 which are away from the side part of the ventilation pipe 1 and are obliquely used for reasonably receiving outdoor wind power, the oblique openings 21 on the two gas-collecting hoods 14 are respectively in the north and south, and when outdoor wind or south wind blows in or blows in the north direction, the wind power can be rapidly collected into the gas-collecting hoods 14 by utilizing the orientation of the oblique openings 21, so that the structure of the gas-collecting hoods 14 is more reasonable due to the arrangement of the oblique openings 21. The far ends of the oblique openings 21 of the two gas collecting hoods 14 are hinged with buckling hoods 25, the two buckling hoods 25 on the two gas collecting hoods 14 rotate and incline in opposite directions, air inlets of the two gas collecting hoods 14 are opened at one side back to the buckling hoods 25, opposite surfaces of the two buckling hoods 25 are provided with oppositely inclined sunk cavities 26, the buckling hoods 25 are hinged with the oblique openings 21 in a manner of matching with a torsion spring and hinging shafts, so that the buckling hoods are ensured to be opened all the time under non-wind blowing (the manner that the torsion spring is matched with the hinging shafts is the prior hinging technology, which is not repeated), when outdoor wind in one direction is received by one windward mechanism 8, the wind enters the gas collecting seat 13 along the gas collecting hoods 14 in an upward-facing manner, meanwhile, the wind blown in the one direction can fall onto the other windward mechanism 8 and enters the sunk cavity 26 of the buckling hood 25 on the other windward mechanism 8 to form air pressure and quickly close the buckling hoods 25 on the other windward mechanism 8, so that the two windward mechanisms 8 rotate simultaneously and the same rotating shaft 16 is simultaneously, and the two windward mechanisms 8 rotate normally and the same direction can form high damping effect when the two windward mechanisms 8 rotate.
