[0002] The installation of ventilation and air exchange devices in elevator steel structure shafts has a significant impact on the safety of elevator operation. Ventilation openings are usually located near the top and bottom of the elevator shaft to facilitate air circulation and remove harmful substances such as smoke and odors from the shaft.

[0003] Many elevator steel structure shafts use filter plates in their ventilation systems to prevent debris from entering the shaft. However, this can also cause some debris to adhere to the filter plates, leading to blockage and affecting the ventilation effect. On the other hand, when the weather is humid, moist air can easily enter the shaft through the ventilation system. When the elevator shaft is damp, it can easily cause safety hazards. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ventilation and air exchange device for an elevator steel structure shaft. The anti-blocking component can make the filter plate vibrate and shake off the debris blocking the filter plate. The dehumidification component can quickly release the locking frame from fixing the placement frame, so as to realize the rapid replacement of the quicklime dehumidification block.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0009] The beneficial effects of this utility model are:

[0010] The advantage of this utility model is that by using the filter plate, L-shaped impact rod and force block in the anti-clogging component, the connecting rod is driven to rotate by the rotating seat, so that the L-shaped impact rod periodically impacts the force block on the filter plate, causing the filter plate to vibrate and shake off the debris blocking the filter plate.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-7 As shown, a ventilation device for an elevator steel structure shaft includes an elevator shaft 1. One side of the elevator shaft 1 is connected to an air outlet frame 101 and an air inlet frame 102, both of which communicate with the elevator shaft 1. Anti-blocking components are installed inside the air outlet frame 101 and the air inlet frame 102 to prevent weeds, dust, and other debris from entering the elevator shaft 1. The anti-blocking components include a filter plate 202, an L-shaped impact rod 303, and a force-bearing block 4. A dehumidification component is also installed inside the air outlet frame 101 and the air inlet frame 102 to prevent moisture from entering the elevator shaft 1. The dehumidification component includes a quicklime dehumidification block 5, a protrusion 6, and a locking frame 7.

[0023] The system utilizes the filter plate 202, L-shaped impact rod 303, and force-bearing block 4 in the anti-clogging component. The rotating seat 305 drives the connecting rod 302 to rotate, causing the L-shaped impact rod 303 to periodically impact the force-bearing block 4 on the filter plate 202, causing the filter plate 202 to vibrate and dislodge the debris blocking it. Then, the bolts are rotated to disassemble the louver 2 and clean up the dislodged debris, improving the cleanliness of the elevator shaft 1. Secondly, the system uses the quicklime dehumidifying block 5, protrusion 6, and locking frame 7 in the dehumidification component. The quicklime dehumidifying block 5 absorbs moisture, preventing moisture from entering the elevator shaft 1 and causing it to become damp, which could lead to safety hazards. By rotating the turntable 703, the locking rod 604 is retracted into the storage slot 602, and the locking frame 7 is quickly released from fixing the placement frame 504, enabling the quick replacement of the quicklime dehumidifying block 5 and improving maintenance efficiency.

[0024] Both the air outlet frame 101 and the air inlet frame 102 are equipped with louvers 2. Two bolts 201 are installed at the top of both frames, with one end of each bolt penetrating the interior of the respective frame and extending into the corresponding louver 2. A filter plate 202 is installed on one side of each louver 2. Support rods 3 are installed inside both the air outlet frame 101 and the air inlet frame 102, and motors 304 are installed on one side of each support rod 3. 4. A rotating seat 305 is connected to one side of the drive. Multiple fan blades 301 are connected to the outside of the rotating seat 305. A connecting rod 302 is connected to one side of the rotating seat 305. An L-shaped impact rod 303 is connected to one side of the connecting rod 302. A force-bearing block 4 that is used in conjunction with the L-shaped impact rod 303 is connected to one side of the filter plate 202. Multiple dampers 401 are connected to one side of each filter plate 202. Each damper 401 is connected to the inner wall of the corresponding air outlet frame 101 and air inlet frame 102.

[0025] Many elevator steel structure shaft ventilation systems use filter plates to prevent debris from entering the shaft. However, this can also lead to some debris adhering to the filter plates, causing blockage and affecting the ventilation effect. When using this equipment, the motor 304 inside the air outlet frame 101 and air inlet frame 102 drives the rotating seat 305, which in turn drives the connecting rod 302 to rotate. The connecting rod 302 then drives the L-shaped impact rod 303 fixed thereon to perform a circular motion, causing one end of the rotating L-shaped impact rod 303 to periodically impact the device installed on... The force-bearing block 4 on one side of the filter plate 202 is connected to the inner wall of the corresponding air outlet frame 101 or air inlet frame 102 via multiple dampers 401. When the L-shaped impact rod 303 strikes the force-bearing block 4, the impact force is transmitted to the filter plate 202, causing it to vibrate. The dampers 401 buffer and limit the amplitude during vibration, and help the filter plate 202 reset during the impact gap, thereby effectively shaking off weeds, dust, and other debris clogging the mesh of the filter plate 202, preventing debris from entering the elevator shaft 1 and maintaining unobstructed airflow. When accumulated debris needs to be cleaned, the bolts 201 fixing the louvers 2 can be unscrewed to remove the louvers 2, thus cleaning off the shaken debris.

[0026] Both the air outlet frame 101 and the air inlet frame 102 are equipped with placement frames 504, and quicklime dehumidifying blocks 5 are installed inside the placement frames 504. Both the air outlet frame 101 and the air inlet frame 102 have sliding grooves 501, and limit blocks 502 are installed inside the sliding grooves 501. The bottoms of the two limit blocks 502 are connected to the tops of the corresponding placement frames 504. A locking frame 7 is connected to one side of both the air outlet frame 101 and the air inlet frame 102. A movable groove 706 is provided inside the locking frame 7, and two protrusions 6 are provided inside the movable groove 706. One end of each of the four protrusions 6 is connected to one side of the corresponding placement frame 504. A storage cylinder 601 is installed inside the two placement frames 504, and a storage slot 602 is provided inside the storage cylinder 601. There is a spring 603, and there are locking rods 604 on both sides of the spring 603. There are locking grooves 605 inside the two protrusions 6. One end of the two locking rods 604 extends into the corresponding locking grooves 605. There are locking grooves 701 on one side of the two locking frames 7. There are release rods 702 connected to one side of the two protrusions 6. One end of the two release rods 702 passes through the corresponding locking grooves 701. There is a gear 705 between the two release rods 702. One side of the gear 705 is rotatably connected to the locking frame 7 through a rotating shaft. There are teeth on one side of the two release rods 702 that are used in conjunction with the gear 705. There is a turntable 703 on one side of the two locking frames 7. There is a control rod 704 connected to one side of the turntable 703. One end of the control rod 704 is connected to the gear 705.

[0027] When the weather is humid, moist air can easily enter the elevator shaft through the ventilation system. A damp elevator shaft can easily lead to safety hazards. This device is installed in a placement frame 504 inside the air outlet frame 101 and air inlet frame 102, containing quicklime dehumidifying blocks 5. When air flows through the placement frame 504, the quicklime dehumidifying blocks 5 absorb moisture from the air, effectively preventing humid air from entering the elevator shaft 1 and reducing safety hazards caused by dampness. The placement frame 504 is embedded in the corresponding sliding groove 501 by a limiting block 502 at the top, ensuring the correct orientation and angle during installation. A protrusion 6 on one side of the placement frame 504 is embedded in the movable groove 706 inside the locking frame 7. In the installed state, the spring 603 inside the storage cylinder 601 pushes the two locking rods 604 to both sides, causing the ends of the locking rods 604 to insert into the protrusion 6. The internal locking groove 605 securely locks the placement frame 504 within the locking frame 7. When the quicklime dehumidifying block 5 needs to be replaced, the turntable 703 is rotated, causing the control lever 704 to rotate. The control lever 704 drives the gear 705 to rotate. Since the gear 705 simultaneously meshes with the teeth on the sides of the two release levers 702, the rotation of the gear 705 drives the two release levers 702 to move. The other end of the release lever 702 pulls the locking lever 604 inside the protrusion 6, causing the locking lever 604 to overcome the elastic force of the spring 603 and retract into the storage groove 602. Once the locking lever 604 is completely disengaged from the locking groove 605, the locking of the protrusion 6 is released, thereby releasing the locking of the placement frame 504. Then, the placement frame 504 can be pulled out from the sliding groove 501 along the guide for quick replacement of the quicklime dehumidifying block 5. After replacement, push the placement frame 504 back to its original position, and the protrusion 6 enters the movable groove 706. Continue to rotate the turntable 703 to retract the locking rod 604 into the storage groove 602. When the locking rod 604 and the locking groove 605 are aligned, release the turntable 703. The locking rod 604 will automatically spring into the locking groove 605 under the action of the spring 603 to complete the locking.

[0028] Working principle:

[0029] Many elevator steel structure shaft ventilation systems use filter plates to prevent debris from entering the shaft. However, this can also lead to some debris adhering to the filter plates, causing blockage and affecting the ventilation effect. When using this equipment, the motor 304 inside the air outlet frame 101 and air inlet frame 102 drives the rotating seat 305, which in turn drives the connecting rod 302 to rotate. The connecting rod 302 then drives the L-shaped impact rod 303 fixed thereon to perform a circular motion, causing one end of the rotating L-shaped impact rod 303 to periodically impact the device installed on... The force-bearing block 4 on one side of the filter plate 202 is connected to the inner wall of the corresponding air outlet frame 101 or air inlet frame 102 via multiple dampers 401. When the L-shaped impact rod 303 strikes the force-bearing block 4, the impact force is transmitted to the filter plate 202, causing it to vibrate. The dampers 401 buffer and limit the amplitude during vibration, and help the filter plate 202 reset during the impact gap, thereby effectively shaking off weeds, dust, and other debris clogging the mesh of the filter plate 202, preventing debris from entering the elevator shaft 1 and maintaining unobstructed airflow. When accumulated debris needs to be cleaned, the bolts 201 fixing the louvers 2 can be unscrewed to remove the louvers 2, thus cleaning off the shaken debris.

[0030] When the weather is humid, moist air can easily enter the elevator shaft through the ventilation system. A damp elevator shaft can easily lead to safety hazards. This device is installed in a placement frame 504 inside the air outlet frame 101 and air inlet frame 102, containing quicklime dehumidifying blocks 5. When air flows through the placement frame 504, the quicklime dehumidifying blocks 5 absorb moisture from the air, effectively preventing humid air from entering the elevator shaft 1 and reducing safety hazards caused by dampness. The placement frame 504 is embedded in the corresponding sliding groove 501 by a limiting block 502 at the top, ensuring the correct orientation and angle during installation. A protrusion 6 on one side of the placement frame 504 is embedded in the movable groove 706 inside the locking frame 7. In the installed state, the spring 603 inside the storage cylinder 601 pushes the two locking rods 604 to both sides, causing the ends of the locking rods 604 to insert into the protrusion 6. The internal locking groove 605 securely locks the placement frame 504 within the locking frame 7. When the quicklime dehumidifying block 5 needs to be replaced, the turntable 703 is rotated, causing the control lever 704 to rotate. The control lever 704 drives the gear 705 to rotate. Since the gear 705 simultaneously meshes with the teeth on the sides of the two release levers 702, the rotation of the gear 705 drives the two release levers 702 to move. The other end of the release lever 702 pulls the locking lever 604 inside the protrusion 6, causing the locking lever 604 to overcome the elastic force of the spring 603 and retract into the storage groove 602. Once the locking lever 604 is completely disengaged from the locking groove 605, the locking of the protrusion 6 is released, thereby releasing the locking of the placement frame 504. Then, the placement frame 504 can be pulled out from the sliding groove 501 along the guide for quick replacement of the quicklime dehumidifying block 5. After replacement, push the placement frame 504 back to its original position, and the protrusion 6 enters the movable groove 706. Continue to rotate the turntable 703 to retract the locking rod 604 into the storage groove 602. When the locking rod 604 and the locking groove 605 are aligned, release the turntable 703. The locking rod 604 will automatically spring into the locking groove 605 under the action of the spring 603 to complete the locking.
