Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model more apparent, exemplary embodiments according to this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments of this utility model. It should be understood that this utility model is not limited to the exemplary embodiments described herein.

[0020] The fully automatic adjustable window according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0021] Figure 1 A schematic diagram of the fully automatic adjustable window structure provided for an embodiment of this utility model.

[0022] Figure 2 This is a schematic diagram of the adjustable windshield assembly and drive assembly provided in an embodiment of the present invention.

[0023] like Figures 1-2 As shown, the fully automatic adjustable window provided in this embodiment of the utility model includes an adjustable window body 1, an adjustable window assembly 2, a drive assembly 3, and a controller (not shown in the figure).

[0024] The adjustable window 1 is equipped with a slide rail (not shown in the figure), a window cavity 11, and a wind speed sensor (not shown in the figure). The slide rail is located on both sides of the window cavity 11. The adjustable window assembly 2 includes an adjustable window body 21 and a roller 22, with the roller located below the window cavity 11. The lower end of the adjustable window body 21 is fixedly wound onto the roller 22. The controller is electrically connected to the drive assembly 3 and the wind speed sensor.

[0025] Specifically, the drive assembly 3 includes a pneumatic motor 31, a coupling 32, and a worm gear reducer 33. The input end of the worm gear reducer 33 is connected to the pneumatic motor 31, the output end of the worm gear reducer 33 is connected to one end of the coupling 32, and the other end of the coupling 32 is connected to the drum 22.

[0026] Specifically, the drive assembly 3 also includes a wire rope assembly 34, a pulley 35, and a counterweight 36. One end of the wire rope assembly 34 is connected to the upper end of the adjustable window body 21, and the other end of the wire rope assembly 34 passes around the pulley 35 and is connected to the counterweight 36.

[0027] The drive assembly 3 can drive the roller 22 to rotate, thereby moving the adjustable window body 21 along the slide rail, thus opening and closing the window cavity 11.

[0028] Furthermore, the adjustable window body 21 is a flexible window panel. Its lower end is fixed to and wound onto the roller 22, and its upper end is connected to steel wire rope assemblies 34 on both sides. The steel wire rope assemblies 34 are wound around pulleys 35 located above the window cavity 11 and connected to a counterweight 36. The steel wire rope assemblies 34 can drive the adjustable window body 21 to move up and down in the slide rail to open and close the window cavity 11.

[0029] Furthermore, the adjustable window assembly 2 also includes a bearing seat 23, which is disposed on both sides of the roller 22 for supporting the roller 22 and limiting the position of the adjustable window body 21.

[0030] Specifically, during rotation, the roller 22 is subjected to various forces, including the gravity of the adjustable window body 21 and the driving force of the drive assembly 3. The bearing seat 23 provides a stable support point for the roller 22, reducing swaying and friction during rotation and ensuring smooth and stable operation. Simultaneously, when the adjustable window body 21 moves up and down, it needs to follow a specific trajectory to ensure accurate opening and closing of the window cavity. The bearing seat 23 acts as a limiter for the adjustable window body 21, preventing lateral deviation or swaying during movement. For example, when the drive assembly 3 drives the roller 22 to rotate, causing the adjustable window body 21 to rise or fall, the bearing seat 23 restricts the adjustable window body 21 to move only in the vertical direction, preventing it from deviating from its normal track.

[0031] For example, a wind speed sensor measures the wind speed signal and sends it to a controller. The controller calculates the actual airflow and compares it with a preset airflow. If there is a difference between the actual and preset airflow, the controller sends a corresponding control signal to the pneumatic motor 31 based on the magnitude and direction of the difference. Upon receiving the control signal, the pneumatic motor 31 drives the roller 22 to rotate, causing the flexible windshield panel to rise or fall, thereby adjusting the size of the ventilation opening (i.e., the window cavity) and achieving automatic airflow regulation.

[0032] Specifically, when the pneumatic motor 31 drives the worm gear reducer 33 to rotate in the forward direction, the worm gear reducer 33 drives the coupling 32 to rotate, which in turn drives the drum 22 to rotate. Consequently, the regulating window body 21 on the drum 22 is wound up. The upper end of the regulating window body 21 moves downward by the coordinated action of the wire rope assembly 34, pulley 35, and counterweight 36, opening the window cavity 11. When the pneumatic motor 31 does not need to work, that is, when the pneumatic motor 31 does not transmit driving force to the worm gear reducer 33, the worm gear reducer 33 can automatically lock the coupling to prevent changes in the opening degree of the regulating window. When the pneumatic motor 31 drives the worm gear reducer 33 to rotate in the reverse direction, the worm gear reducer 33 drives the coupling 32 to rotate, thereby driving the drum 22 to rotate. In turn, the adjusting window body 21 on the drum 22 is wound up. The upper end of the adjusting window body moves upward by the coordinated action of the wire rope group 34, pulley 35 and counterweight 36, thus closing the window cavity 11.

[0033] Furthermore, the material of the adjustable windshield body 21 is a new flame-retardant material.

[0034] Preferably, the flame-retardant new material is a silicon-titanium alloy fireproof material, which has the characteristics of flame retardancy and high strength.

[0035] The fully automatic adjustable window provided in this embodiment of the invention features linear lifting and lowering motion. Through the coordinated action of a controller, wind speed sensor, adjustable window assembly, and drive assembly, the window cavity of the adjustable window body is automatically opened and closed. The opening degree of the adjustable window is a linear and continuous variable, which not only reduces the calculation workload for ventilation operators but also provides high precision in controlling the opening degree. The driving force for the adjustable window is provided by a pneumatic motor. The pneumatic motor does not generate sparks during operation, meeting the requirements of underground coal mine operations. The worm gear reducer has a self-locking function upon shutdown, preventing changes in the position of the adjustable window body from affecting the ventilation volume due to changes in the window opening degree.

[0036] Furthermore, the fully automatic adjustable window also includes a window door 4, which is assembled with the adjustable window body 1.

[0037] Figure 3 This is a schematic diagram of a windshield door provided in an embodiment of the present utility model.

[0038] Figure 4 Another schematic diagram of the windshield door body provided in this embodiment of the utility model.

[0039] like Figures 3-4 As shown, the windshield door 4 of this utility model is provided with a pedestrian door 41 and a cylinder drive device 42. The cylinder drive device 42 is used to drive the pedestrian door 41 to open and close.

[0040] Furthermore, the cylinder drive device 42 includes a cylinder tail support 421, a cylinder 422, and a cylinder front support 423.

[0041] Specifically, the cylinder tail support 421 is located on the upper end of the pedestrian door 41, that is, on the windshield door 4, and the cylinder front support 423 is located on the pedestrian door 41. One end of the cylinder 422 is hinged to the windshield door through the cylinder tail support 421, and the other end is hinged to the pedestrian door through the cylinder front support 423.

[0042] According to the technical solution provided by this utility model, the pedestrian door is driven by a cylinder drive device, which effectively reduces the labor intensity of workers manually opening and closing the pedestrian door, and at the same time avoids the problem of workers not closing the door after passing through the pedestrian door.

[0043] This utility model provides a ventilation system, including the aforementioned fully automatic adjustable vent.

[0044] Figure 5 A schematic diagram of a ventilation system provided for an embodiment of this utility model.

[0045] like Figure 5 As shown, this utility model provides a ventilation system, including a pneumatic control system for a damper and two fully automatic adjustable dampers containing damper doors. The pedestrian doors of the two fully automatic adjustable dampers are interlocked through the pneumatic control system.

[0046] For example, the cylinder drive device on the door of each fully automatic adjustable window is connected to the pneumatic control system of the damper. Taking fully automatic adjustable windows A and B as examples, the cylinder tail support, cylinder, and cylinder front support of fully automatic adjustable window A are connected to the pneumatic control system through air pipes, and the same applies to fully automatic adjustable window B. The pneumatic control system of the damper includes an air source (such as an air compressor), control valves (such as solenoid directional valves, throttle valves, etc.), and connecting pipelines.

[0047] Control Principle: When a pedestrian approaches the pedestrian door 501 of the fully automatic adjustable window A, an opening signal is triggered (such as an electrical signal from a sensor switch or an electrical signal triggered by manual opening). This signal is transmitted to the pneumatic control system. Upon receiving the signal, the system controls the solenoid directional valve of the fully automatic adjustable window A to switch, allowing compressed air from the air source to enter the rodless chamber of the cylinder of the fully automatic adjustable window A, pushing the piston to extend the piston rod and open the pedestrian door of the fully automatic adjustable window A. Simultaneously, the logic control unit (such as a programmable logic controller PLC or a pneumatic control circuit) within the pneumatic control system activates, changing the state of the solenoid directional valve of the fully automatic adjustable window B, cutting off the air intake passage of the cylinder of the fully automatic adjustable window B, thus preventing the pedestrian door 502 of the fully automatic adjustable window B from opening.

[0048] In summary, according to the technical solution provided by this utility model, the pedestrian door is driven by a cylinder drive device, which effectively reduces the labor intensity of workers manually opening and closing the pedestrian door, and at the same time avoids the problem of workers not closing the door after passing through the pedestrian door. Two cylinder drive devices containing fully automatic adjustable air windows are connected to the air door pneumatic control system to achieve interlocking of the two pedestrian doors, thereby ensuring that the two pedestrian doors cannot be opened at the same time to prevent short circuits.
