[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution in the implementation mode of the present invention will be further clearly and completely described below in combination with the drawings in the implementation mode of the present invention. Obviously, the described implementation mode is only a part of the implementation mode of the present invention, not all implementation modes.

[0025] like Figure 1 As shown, an embodiment of the present invention provides a personnel air gate interlock and power distribution device: including an input shaft 1, a gear set 2, an incomplete gear set, an incomplete gear set shaft, a stop device 3, an inner door output shaft, an outer door output shaft, etc.

[0026] The incomplete gear set includes an inner door incomplete gear set and an outer door incomplete gear set, which are symmetrically arranged with gear set 2 as the axis of symmetry. In the incomplete gear set, each incomplete gear has only a partial gear on its circumference; two adjacent incomplete gears in the incomplete gear set can mesh on the toothed side, and two adjacent incomplete gears can disengage on the toothless side. The incomplete gear set shaft includes a first-stage incomplete gear set shaft 16, an inner door incomplete gear set shaft, and an outer door incomplete gear set shaft; the first-stage incomplete gear set shaft 16 is symmetrically arranged with gear set 2 as the axis of symmetry; the inner door incomplete gear set shaft and the outer door incomplete gear set shaft are symmetrically arranged with gear set 2 as the axis of symmetry. The inner door output shaft and the outer door output shaft are symmetrically arranged with gear set 2 as the axis of symmetry.

[0027] In this embodiment, the inner door incomplete gear set includes a first-stage inner door incomplete gear set, a second-stage inner door incomplete gear set, and a third-stage inner door incomplete gear set. The outer door incomplete gear set includes a first-stage outer door incomplete gear set, a second-stage outer door incomplete gear set, and a third-stage outer door incomplete gear set. The inner door incomplete gear set shaft includes a second-stage inner door incomplete gear set shaft 22 and a third-stage inner door incomplete gear set shaft 23. The outer door incomplete gear set shaft includes a second-stage outer door incomplete gear set shaft 21 and a third-stage outer door incomplete gear set shaft.

[0028] The inner door output shaft includes an inner door balancing valve output shaft 12 (output shaft I), an inner door locking and unlocking output shaft 13 (output shaft II), and an inner door opening and closing output shaft 14 (output shaft III). The inner door balancing valve output shaft 12 is connected to the inner door balancing valve to control whether the inner door balancing valve is opened or closed; the inner door locking and unlocking output shaft 13 is connected to the inner door panel locking device to control whether the inner door panel locking device is unlocked or locked; the inner door opening and closing output shaft 14 is connected to the inner door panel opening device to control whether the inner door panel is opened or closed. The outer door output shaft includes an outer door balancing valve output shaft 18 (output shaft IV), an outer door locking and unlocking output shaft 19 (output shaft V), and an outer door opening and closing output shaft 20 (output shaft VI). The outer door balancing valve output shaft 18 is connected to the outer door balancing valve to control the outer door balancing valve to open or close; the outer door locking and unlocking output shaft 19 is connected to the outer door panel locking device to control the outer door panel locking device to unlock or lock; the outer door switch door output shaft 20 is connected to the outer door panel opening device to control the outer door panel to open or close.

[0029] In this embodiment, the input shaft 1 transmits torque to the first-stage incomplete gear set shaft 16 through the gear set 2. A rotation stop device 3 is provided on the first-stage incomplete gear set shaft 16, which limits the first-stage incomplete gear set shaft 16 to approximately 360°. Initially, the first-stage incomplete gear set shaft 16 is configured to rotate 180° clockwise and 180° counterclockwise. The first-stage incomplete gear set for the inner door includes a first-stage incomplete gear set driving wheel 4 and a first-stage incomplete gear set driven wheel 5; the first-stage incomplete gear set for the outer door includes a first-stage incomplete gear set driving wheel 15 and a first-stage incomplete gear set driven wheel 17. At the same time, with the gear set 2 as the axis of symmetry, the first-stage incomplete gear set driving wheel 4 and the first-stage incomplete gear set driving wheel 15 are symmetrically arranged on the first-stage incomplete gear set shaft 16. The driven pulley 5 of the inner door's first-stage incomplete gear set is mounted on the inner door's second-stage incomplete gear set shaft 22, while the driven pulley 17 of the outer door's first-stage incomplete gear set is mounted on the outer door's second-stage incomplete gear set shaft 21. The inner door's first-stage incomplete gear set driving pulley 4 faces away from the outer door's first-stage incomplete gear set driving pulley 15, and the inner door's first-stage incomplete gear set driven pulley 5 and the outer door's first-stage incomplete gear set driven pulley 17 are arranged symmetrically with the gear set 2 as the axis of symmetry. Therefore, in this embodiment, when the first-stage incomplete gear set shaft 16 rotates clockwise, the inner door's first-stage incomplete gear set driving pulley 4 and the inner door's first-stage incomplete gear set driven pulley 5 engage, driving the inner door's second-stage incomplete gear set shaft 22 to rotate. Simultaneously, the toothless side of the outer door's first-stage incomplete gear set driving pulley 15 rotates relative to the outer door's first-stage incomplete gear set driven pulley 17, but the outer door's second-stage incomplete gear set shaft 21 does not rotate.

[0030] The second-stage incomplete gear set for the inner door includes a driving wheel 7, a first driven wheel 6, and a second driven wheel 8. The driving wheel 7 is mounted on the shaft 22 of the second-stage incomplete gear set, the first driven wheel 6 is mounted on the shaft 23 of the third-stage incomplete gear set, and the second driven wheel 8 is mounted on the door opening / closing output shaft 14. The first driven wheel 6 and the second driven wheel 8 are symmetrically arranged around the driving wheel 7. When the second-stage incomplete gear set shaft 22 of the inner door rotates, the second-stage incomplete gear set driving wheel 7 of the inner door first engages with the first driven wheel 6 of the second-stage incomplete gear set of the inner door, and transmits power to the third-stage incomplete gear set shaft 23 of the inner door, driving the third-stage incomplete gear set shaft 23 of the inner door to rotate; at this time, the toothless side of the second-stage incomplete gear set driving wheel 7 of the inner door and the second driven wheel 8 of the second-stage incomplete gear set of the inner door rotate relative to each other, but the inner door switch output shaft 14 does not rotate.

[0031] The inner door's third-stage incomplete gear set includes a driving wheel 10, a first driven wheel 9, and a second driven wheel 11. The driving wheel 10 is mounted on the inner door's third-stage incomplete gear set shaft 23, the first driven wheel 9 is mounted on the inner door balance valve output shaft 12, and the second driven wheel 11 is mounted on the inner door locking and unlocking output shaft 13. The first driven wheel 9 and the second driven wheel 11 are symmetrically arranged around the driving wheel 10. When the inner door's third-stage incomplete gear set shaft 23 rotates, the driving wheel 10 and the first driven wheel 9 first engage, transmitting power to the inner door balance valve output shaft 12. The inner door balancing valve output shaft 12 is connected to the inner door balancing valve. Rotation of the inner door balancing valve output shaft 12 drives the inner door balancing valve to open. After the inner door third-stage incomplete gear set shaft 23 rotates 180° and the inner door third-stage incomplete gear set driving wheel 10 meshes with the first driven wheel 9 of the inner door third-stage incomplete gear set, the inner door balancing valve output shaft 12 stops rotating, and the pressure inside and outside the inner door reaches equilibrium. At this point, the toothed side of the inner door third-stage incomplete gear set driving wheel 10 rotates to the toothed side of the second driven wheel 11 of the inner door third-stage incomplete gear set, meshing with the second driven wheel 11 of the inner door third-stage incomplete gear set, and the inner door locking and unlocking output shaft 13 rotates. The inner door locking and unlocking output shaft 13 is connected to the inner door panel locking device. Rotation of the inner door locking and unlocking output shaft 13 activates the inner door panel locking device, unlocking the locked inner door panel.

[0032] After the inner door's third-stage incomplete gearset driving wheel 10 meshes with the second driven wheel 11 of the third-stage incomplete gearset, the inner door's second-stage incomplete gearset shaft 22 rotates 180°, and the second-stage incomplete gearset driving wheel 7 also meshes with the first driven wheel 6 of the second-stage incomplete gearset. The second-stage incomplete gearset driving wheel 7 and the second driven wheel 8 of the second-stage incomplete gearset begin to mesh, while the first driven wheel 6 of the second-stage incomplete gearset remains stationary. At this point, the inner door's opening and closing output shaft 14 rotates, connecting to the inner door panel opening device and causing the inner door panel to open. After the inner door panel opens, the inner door's first-stage incomplete gearset driving wheel 4 also meshes with the first-stage incomplete gearset driven wheel 5. At this point, the first-stage incomplete gearset shaft 16 rotates 180°, triggering the anti-rotation device 3, preventing the first-stage incomplete gearset shaft 16 from rotating further. At this time, the personnel air lock has completed the inner door pressure balance, inner door unlocking and inner door panel opening actions; at this time, the input shaft 1 is set to rotate only in the reverse direction.

[0033] Manually or by a pre-set inner door closing control switch (electrically), the inner door opening and closing output shaft 14 (output shaft III), the inner door locking and unlocking output shaft 13 (output shaft II), and the inner door balancing valve output shaft 12 (output shaft I) can be sequentially rotated in opposite directions, thereby correspondingly closing the inner door panel of the personnel air lock, locking the inner door, and closing the inner door balancing valve. At the same time, the inner door incomplete gear set and the inner door incomplete gear set shaft return to their initial state, and the first-stage incomplete gear set shaft 16 also rotates counterclockwise back to its initial state.

[0034] At this time, if the input shaft 1 transmits the torque to the first-stage incomplete gear set shaft 16 through the gear set 2, the first-stage incomplete gear set shaft 16 will continue to rotate counterclockwise; since the outer door incomplete gear set, the outer door incomplete gear set shaft, and the outer door output shaft are symmetrically arranged with the inner door incomplete gear set, the inner door incomplete gear set shaft, and the inner door output shaft with the gear set 2 as the symmetry axis; as the first-stage incomplete gear set shaft 16 rotates counterclockwise, the outer door first-stage incomplete gear set driving wheel 15 is engaged with the outer door first-stage incomplete gear set driven wheel 17, driving the outer door second-stage incomplete gear set shaft 21 to rotate; at the same time, the toothless side of the inner door first-stage incomplete gear set driving wheel 4 and the inner door first-stage incomplete gear set driven wheel 5 rotate relative to each other, but the inner door second-stage incomplete gear set shaft 22 does not rotate. Power is then transmitted sequentially through the outer door's second-stage and third-stage incomplete gear sets to the outer door's third-stage incomplete gear set shaft, the outer door balancing valve output shaft 18 (output shaft IV), the outer door locking and unlocking output shaft 19 (output shaft V), and the outer door switch output shaft 20 (output shaft VI). This drives the personnel air lock to balance the outer door pressure, unlock the outer door, and open the outer door panel. The anti-rotation device 3 is triggered, preventing the first-stage incomplete gear set shaft 16 from further rotation. At this point, the input shaft 1 is configured to rotate only in the reverse direction, operating in a similar manner to the inner door side of the personnel air lock.

[0035] Manually or by activating the preset outer door closing control switch (electrically), the outer door opening and closing output shaft 20 (output shaft VI), the outer door locking and unlocking output shaft 19 (output shaft V), and the outer door balancing valve output shaft 18 (output shaft IV) can be sequentially rotated in opposite directions, thereby correspondingly closing the outer door panel of the personnel air lock, locking the outer door, and closing the outer door balancing valve. At the same time, the outer door incomplete gear set and the outer door incomplete gear set shaft return to their initial state, and the first stage incomplete gear set shaft 16 also rotates clockwise back to its initial state.

[0036] In this embodiment, the clockwise rotation of the first-stage incomplete gear set shaft 16 is configured to drive the inner door output shaft to achieve inner door pressure balance, inner door unlocking, and inner door panel opening of the personnel air lock, while the counterclockwise rotation of the first-stage incomplete gear set shaft 16 is configured to drive the outer door output shaft to achieve outer door pressure balance, outer door unlocking, and outer door panel opening of the personnel air lock. Depending on the situation, the reverse arrangement can also be adopted, that is, the counterclockwise rotation of the first-stage incomplete gear set shaft 16 is configured to drive the inner door output shaft to achieve inner door pressure balance, inner door unlocking, and inner door panel opening of the personnel air lock, while the clockwise rotation of the first-stage incomplete gear set shaft 16 is configured to drive the outer door output shaft to achieve outer door pressure balance, outer door unlocking, and outer door panel opening of the personnel air lock.

[0037] When the inner door output shafts (output shafts I, II, and III) are not in their initial positions, the outer door output shafts (output shafts IV, V, and VI) cannot rotate. Similarly, when the outer door output shafts (output shafts IV, V, and VI) are not in their initial positions, the inner door output shafts (output shafts I, II, and III) cannot rotate. This ensures that at least one of the two doors of the personnel air lock is sealed at all times, achieving the inner and outer door interlocking function of the personnel air lock.

[0038] In this embodiment of the present invention, the personnel air gate interlock, pressure balancing, locking and unlocking, and door panel opening and closing mechanisms are all integrated into the power distribution gearbox, which sequentially outputs torque to open the inner and outer door balance valves, unlock the door panels, open the door panels, and reverse these operations. The personnel air gate interlock and power distribution device provided in this embodiment ensures that only one of the inner and outer doors of the personnel air gate is unsealed, thus ensuring that the personnel air gate remains sealed at all times.

[0039] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
