Description

Technical Field

[0001] This utility model belongs to the field of sandproof window technology, specifically relating to a smart sandproof window for textile air conditioning. Background Technology

[0002] Currently, each air-conditioned room has a window with a filter bag for fresh air. In dusty weather, the fresh air window without a filter bag can only be closed manually, resulting in large fluctuations in air conditioning temperature and humidity. The current design of fresh air windows on the first floor of the workshop means that almost all fresh air windows in the park are close to the road. In windy weather, dust raised by passing vehicles will be drawn into the air-conditioned room through the fresh air window, causing pollution of the inhaled fresh air.

[0003] Currently, an existing sunshade louver with waterproof and drainage functions, with announcement number CN218624013U, includes a louver frame, a louver tilting assembly, waterproof gaskets, a motor, and a conversion bracket. The louver tilting assembly is fixed inside the louver frame, and waterproof gaskets are fixed at the four corners of the louver tilting assembly on the inner side of the louver frame. A motor is also fixed to the louver frame. This sunshade louver with waterproof and drainage functions features curved louvers with a guide angle design for drainage and sand prevention; waterproof gaskets at the frame joints for waterproofing; a guide angle design on the lower frame for drainage and sand prevention; a guide plate with a guide angle design for drainage and sand prevention; a bushing on the louver tilting assembly to reduce noise and wear; a light-blocking plate on the upper frame, ensuring complete light control when the system is closed, providing excellent sunshade effect; self-tapping screws for secure and aesthetically pleasing louver fixing; and louvers with fixing grooves for high overall blade strength.

[0004] However, there is a problem: the device cannot automatically replace the filter cloth. Utility Model Content

[0005] This solution provides a smart sandproof window for textile air conditioning, which solves the problem that the filter cloth of existing sandproof windows cannot be automatically replaced.

[0006] This solution provides a smart sand-proof window for textile air conditioning, including:

[0007] Sandproof frame;

[0008] Filter cloth: The filter cloth is placed inside the sandproof frame;

[0009] Flow guiding mechanism: used to adjust the ambient wind pressure on the filter cloth;

[0010] Airflow sensor: used to monitor the airflow volume within the connecting pipe;

[0011] Replacement mechanism: used for replacing filter cloth;

[0012] Controller: The replacement mechanism and the controller are electrically connected.

[0013] The principle behind this solution is as follows: a new filter cloth is installed inside the sand-proof frame, and the airflow guiding mechanism is adjusted to a preset position to optimize airflow distribution. The airflow sensor begins to monitor the magnitude of the airflow entering the room, and the controller initializes and prepares to receive data. Outside air is first filtered through the filter cloth to remove dust, sand, and other particulate matter.

[0014] Then, the airflow guiding mechanism automatically adjusts its angle or position according to changes in ambient wind pressure to ensure that the airflow passes evenly through the filter cloth, avoiding local blockage or poor airflow, while also preventing the filter cloth from being damaged due to excessive ambient wind pressure.

[0015] The airflow sensor continuously monitors changes in airflow speed and pressure, transmitting the data to the controller in real time. When a significant increase in airflow resistance is detected (indicating potential filter cloth blockage) or the airflow speed drops below a preset threshold, the controller issues a command to activate the replacement mechanism. The replacement mechanism removes the old filter cloth from the sandproof frame and automatically installs a new filter cloth into place.

[0016] The beneficial effects of this solution are: 1. The automatic filter cloth replacement function reduces the need for manual intervention, improves maintenance efficiency, and reduces operating costs. 2. It ensures that the filter cloth is always in optimal working condition, avoiding poor ventilation or decreased filtration efficiency due to filter cloth clogging.

[0017] Furthermore, the replacement mechanism includes a driving component, a drive shaft, and a driven shaft. The drive shaft and the driven shaft cooperate with each other. The driven shaft is rotatably disposed at the upper end of the sandproof frame, and the drive shaft is rotatably disposed at the lower end of the sandproof frame. One end of the filter cloth is fixedly connected to the drive shaft, and the other end is wound and fixed on the driven shaft. The driving component is used to drive the drive shaft to rotate.

[0018] New filter cloth is pre-installed on the driven shaft, while the drive shaft is empty or has a small amount of pre-wound filter cloth. The filter cloth filters outside air as it passes through the sand-proof window. Over time, dust and particulate matter accumulate on the filter cloth, increasing airflow resistance.

[0019] An airflow sensor continuously monitors the airflow volume within the connecting pipe. When a significant increase in airflow resistance is detected (indicating potential filter cloth blockage) or the airflow velocity drops below a preset threshold, the controller determines that the filter cloth needs replacement. The controller issues a command to activate the drive mechanism. The drive mechanism rotates the drive shaft, pulling a new filter cloth from the driven shaft and replacing the used filter cloth inside the sandproof frame. The used filter cloth is then rolled onto the drive shaft. Once the new filter cloth is fully unfolded and covers the entire filtration area, the drive mechanism stops operating.

[0020] Our system ensures the filter cloth is always in optimal working condition through real-time monitoring and automatic replacement, preventing poor ventilation or decreased filtration efficiency caused by filter cloth clogging. Furthermore, filter cloth replacement can be performed without shutting down the system.

[0021] Furthermore, a cloth winding drum is fixedly mounted on both the drive shaft and the driven shaft, and the cloth winding drum is used to wind up the filter cloth. This mechanism employs a cloth winding drum design, which is simple and reliable in structure, reducing the possibility of mechanical failure. At the same time, the cooperation between the cloth winding drums on the drive shaft and the driven shaft ensures smooth transmission of the filter cloth, avoiding problems such as jamming or breakage.

[0022] Furthermore, the flow guiding mechanism includes flow guiding blades, a flow guiding frame, and a rotating component. The flow guiding frame is fixedly connected to the connecting pipe and cooperates with the filter cloth. Multiple flow guiding blades are provided, and the multiple flow guiding blades are arranged linearly in the flow guiding frame. The flow guiding blades are rotatably connected to the flow guiding frame, and the rotating component is used to drive the flow guiding blades to rotate.

[0023] During normal operation, the airflow guide vanes open at a preset angle to evenly distribute the airflow entering the connecting pipe throughout the entire working space, thus avoiding airflow concentration, improving ventilation efficiency, and reducing the load on the filter cloth per unit area.

[0024] When the external wind pressure is too high, the sandproof frame cannot return to its original position due to the pressure of the strong wind. After receiving the timer signal, the controller starts the rotating component. The rotating component drives the guide vanes to reduce the opening (close to closing), limiting the air intake and reducing the impact of wind pressure on the sandproof frame. This achieves "active pressure reduction" and protects the filter cloth and mechanical structure.

[0025] Furthermore, it also includes a connecting pipe, the sandproof frame is slidably and sealingly connected to the connecting pipe, the driving component includes a rack, a gear, a reset component and a toggle component, the gear is rotatably connected to the sandproof frame, the toggle component is fixedly connected to the drive shaft, the gear has a ring of ratchet teeth inside, the toggle component cooperates with the ratchet teeth, the rack is fixedly connected to the connecting pipe, the gear cooperates with the rack, and the reset component is used to reset the sandproof frame.

[0026] Airflow sensors can determine whether the filter is clogged by the amount of airflow. However, due to the large amount of cotton and dust in textile factories, airflow sensors are easily blocked, causing them to malfunction and making it impossible to replace the filter cloth.

[0027] The air conditioner in this design maintains a constant air intake. When the filter cloth becomes clogged, the air conditioner increases the suction force on the filter cloth in order to draw in enough air. At this time, the sandproof frame is pulled by a large suction force, causing it to move inward. The movement of the sandproof frame drives the gear to move. Because the gears mesh with each other, they rotate forward when they move. The rotation of the gear causes the ratchet to rotate. The rotation of the ratchet contacts the actuating component, causing the actuating component to rotate. The rotation of the actuating component drives the drive shaft to rotate. The rotation of the drive shaft pulls a new filter cloth out from the driven shaft, replacing the used filter cloth in the sandproof frame.

[0028] When the filter cloth inside the sand filter is replaced with a new one, the air conditioner's suction power decreases, and the sand filter returns to its original position under the action of the reset component. During the return, the gear reverses, but since the ratchet does not drive the actuating component when it reverses, the drive shaft does not rotate.

[0029] This organization utilizes changes in the suction of the air conditioning system as a trigger mechanism to achieve automatic replacement of the filter cloth without the need for additional sensors or manual intervention.

[0030] Furthermore, it also includes a pressure switch, a timer, and an alarm. The pressure switch is fixedly connected to the connecting pipe and cooperates with the sandproof frame. The alarm is installed on the outer wall of the connecting pipe. The timer, the flow guiding mechanism, and the alarm are all connected to the controller.

[0031] There are two reasons why the sand filter might move inward: one is that the filter is clogged, causing the increased air conditioning suction to pull the sand filter away; the other is that the external wind pressure is too high, causing the sand filter to move.

[0032] When the sand-proof frame moves inward, the filter cloth will be automatically replaced, and a pressure switch will be activated. The pressure switch will send an electrical signal to the controller, which will start a timer. If the sand-proof frame does not return to its original position within the set time (0.5-1 minute), it indicates that the external wind pressure may be too high. The controller will then activate the airflow control mechanism to reduce the wind pressure.

[0033] If the device fails to return to its original position after the set time (0.5-1 minute), the timer sends an electrical signal to the controller, which then activates the alarm, indicating that the device is not functioning properly.

[0034] Our organization employs a tiered response system: Phase 1: Automatic filter cloth replacement (to address blockage); Phase 2: Airflow adjustment (to address air pressure); Phase 3: Alarm notification (for system failure); thus upgrading from "passive handling" to "proactive response".

[0035] Furthermore, the reset component includes a cylinder and a first spring. The cylinder includes a cylinder body, a push rod, and a piston. The cylinder body is fixedly connected to the connecting pipe, and the piston is slidably and sealingly connected to the cylinder body. One end of the first spring is fixedly connected to the piston, and the other end is fixedly connected to the cylinder body. One end of the push rod is fixedly connected to the piston, and the other end is fixedly connected to the sandproof frame.

[0036] Initially, the piston is positioned within the cylinder, and the push rod is extended, keeping the sand shield in its normal operating position. The first spring is slightly compressed or stretched, providing a preload to maintain the sand shield's positional stability.

[0037] As dust and particulate matter gradually accumulate on the filter cloth, airflow resistance increases, and the air conditioning system increases suction to draw in enough air. This increased suction pulls the sand filter frame inward, causing it to move along the sliding seal of the connecting pipe. This movement of the sand filter frame drives a piston within the cylinder via a push rod, further compressing or stretching the first spring.

[0038] As the sand-proof frame moves, the gears begin to rotate clockwise, driving the drive shaft to rotate via ratchet and actuating mechanism, unfolding the new filter cloth and replacing the old one. Once the new filter cloth is fully unfolded and covers the entire filtration area, the suction decreases. Under the action of the first spring, the piston pushes the push rod, returning the sand-proof frame to its initial position.

[0039] The combination of springs and cylinders in this mechanism provides stronger restoring force, ensuring that the sandproof frame can return to its original position smoothly even under strong suction or external wind pressure.

[0040] Furthermore, it also includes an air jet pipe, the connecting pipe having a slag discharge port, the air jet pipe being fixedly connected to the sand-proof frame, and the air jet pipe cooperating with the slag discharge port, and the air outlet of the cylinder being connected to the air jet pipe.

[0041] The sand filter frame is in its normal operating position, the new filter cloth covers the entire filtration area, and the jet pipe is in standby mode. As dust and particulate matter gradually accumulate on the filter cloth, increasing airflow resistance, the air conditioning system increases suction to draw in sufficient air. This increased suction pulls the sand filter frame inward, causing it to move along the sliding seal of the connecting pipe. Simultaneously, the gear begins to rotate forward, driving the drive shaft to rotate via ratchet and actuating mechanism, unfolding the new filter cloth and replacing the old one.

[0042] During the replacement of the filter cloth, the piston movement inside the cylinder generates compressed gas, which enters the jet pipe through the outlet. The jet pipe sprays high-pressure gas into the slag discharge port according to a preset timing or triggered by the controller, discharging the slag and particles that fall off during filter cloth replacement. This prevents particles from accumulating at the sliding joint of the connecting pipe, which could prevent the sand-proof frame from sliding.

[0043] Once the new filter cloth is fully unfolded and covers the entire filtration area, the suction force decreases. Under the action of the first spring, the piston pushes the push rod, returning the sand-proof frame to its initial position.

[0044] This solution uses an air jet to clean up particles that have fallen from the old filter cloth, preventing these impurities from re-entering the sliding joints of the connecting pipes and causing the sand-proof frame to malfunction. The design of the slag discharge port ensures that the blown-off dust and particles can be discharged in a timely manner, preventing them from accumulating inside the equipment and causing secondary pollution.

[0045] Furthermore, it also includes a magnet, which is fixedly connected to the connecting pipe. The sand-proof frame is equipped with a ferromagnetic material, and the magnet cooperates with the ferromagnetic material. Because the sand-proof frame easily creates a force balance when moving, preventing it from reciprocating, this solution uses the attractive force of the magnet as a threshold control mechanism. When the external force (such as air conditioning suction) gradually increases but is insufficient to overcome the magnetic force, the system remains stationary (balanced). Once the external force exceeds the magnetic critical point, the sand-proof frame is suddenly pulled, and the magnetic force "releases" its obstructive effect; during resetting, the magnetic force "pulls back" the sand-proof frame, achieving precise positioning and accelerated resetting.

[0052] Example 1, as shown in the attached document Figure 1 , Figure 2 As shown:

[0053] This solution provides a smart sandproof window for textile air conditioning. The sandproof frame 3 is rectangular, and an airflow sensor 16 is located on the left side of the guide vanes 4, which are rotatably connected to the guide frame 5. The airflow sensor 16 is fixed to the guide frame 5. Both the drive shaft 13 and the driven shaft 15 are placed inside the sandproof frame 3. The driven shaft 15 is rotatably connected to the upper end of the sandproof frame 3, and the drive shaft 13 is rotatably connected to the lower end of the sandproof frame 3. The sandproof frame is fixed to the guide frame 5. A fixing bracket 23 is used to fix the guide frame 5.

[0054] The drive shaft 13 is fixed with a dirty cloth roll 19 for winding dirty filter cloth 14, and the driven shaft 15 is fixed with a fresh cloth roll 18 for winding clean filter cloth 14. The drive component is a motor 17, which drives the drive shaft 13 to rotate. When the filter cloth 14 needs to be replaced, the motor 17 starts, causing the drive shaft 13 to rotate. The dirty cloth roll 19 winds the used filter cloth onto it, while the clean filter cloth emerges from the fresh cloth roll 18 and comes to the front of the guide frame 5 to prevent dust from entering. The right side of the filter cloth 14 is the outside environment, and the left side is the interior environment.

[0055] In operation, a new filter cloth 14 is installed inside the sandproof frame 3, and the guide vanes 4 are adjusted to a preset position to optimize airflow distribution. The airflow sensor 16 begins to monitor the airflow entering the room, and the controller initializes and prepares to receive data. Outside air is first filtered through the filter cloth 14 to remove dust, sand, and other particulate matter.

[0056] Then, the guide vanes 4 can automatically adjust their angle or position according to changes in ambient wind pressure to ensure that the airflow passes through the filter cloth evenly, avoid local blockage or poor airflow, and prevent the filter cloth from being damaged due to excessive ambient wind pressure.

[0057] Airflow sensor 16 continuously monitors changes in airflow speed and pressure, transmitting the data to the controller in real time. When a significant increase in airflow resistance is detected (indicating potential filter cloth blockage) or the airflow speed drops below a preset threshold, the controller issues a command to start motor 17. Motor 17 drives the drive shaft to rotate, pulling a new filter cloth 14 from the driven shaft 15, replacing the used filter cloth 14 inside the sandproof frame 3. The used filter cloth 14 is then rolled onto the drive shaft 13. Once the new filter cloth 14 is fully unfolded and covers the entire filtration area, motor 17 stops operating.

[0058] This solution ensures that the filter cloth 14 is always in optimal working condition through real-time monitoring and automatic replacement, avoiding poor ventilation or decreased filtration efficiency caused by filter cloth 14 clogging. Furthermore, the system can replace the filter cloth 14 without shutting down the machine.

[0059] Example 2, as shown in the attached document Figure 3 As shown:

[0060] This solution provides a smart sandproof window for textile air conditioning. The sandproof frame 3 is rectangular and is installed inside a connecting pipe 1. One end of the connecting pipe 1 is connected to the outside, and the other end is connected to the air conditioner. The sandproof frame 3 slides within the connecting pipe 1.

[0061] A guide frame 5 is provided on the left side of the connecting pipe 1. Eight guide vanes 4 are provided on the guide frame 5. The guide vanes 4 are arranged linearly and are rotatably connected to the guide frame 5. The guide vanes 4 are located at the air inlet of the connecting pipe 1. A slag discharge port 2 is provided at the bottom of the connecting pipe 1 for discharging particulate impurities.

[0062] The flow guiding mechanism is electrically powered, with an electric cylinder driving the guide vanes to rotate. The electric cylinder is fixedly connected to the connecting pipe 1. Mechanical mechanisms, on the other hand, automatically adjust the flow by using wind power to move the baffle plate 18.

[0063] Four cylinders 6 are installed at the four corners of the connecting pipe 1. Each cylinder 6 includes a piston 10, a cylinder body, and a push rod 9. The push rods 9 of the cylinders 6 are fixed at the four corners of the sandproof frame 3, and the four cylinders 6 extend and retract synchronously through an existing synchronizing device. The piston 10 is fixedly connected to the push rod 9, and the piston 10 is slidably and sealingly connected to the cylinder body. One end of the first spring 22 is fixedly connected to the piston 10, and the other end is fixedly connected to the cylinder body.

[0064] As attached Figure 3 , Figure 4 , Figure 5 As shown:

[0065] The upper frame of the sandproof frame 3 has a driven shaft 15 inside, around which a filter cloth 14 is wound. The other end of the filter cloth 14 passes through the center of the sandproof frame 3 and is fixed to the drive shaft 13 inside the lower frame of the sandproof frame 3. Both the driven shaft 15 and the drive shaft 13 are slidably connected to the sandproof frame 3. The size of the filter cloth 14 is exactly the same as the opening of the sandproof frame 3, so that air must pass through the filter cloth 14 to pass through the sandproof frame 3.

[0066] A gear 8 is also provided concentrically on the drive shaft 13 of the sandproof frame 3. The gear 8 is rotatably connected to the sandproof frame 3 and meshes with the gears. The rack 7 is fixedly connected to the connecting pipe 1. The gear 8 and the rack 7 are located in the inner groove of the connecting pipe 1, and the inner groove is sealed to prevent air leakage.

[0067] The gear 8 has a ring of ratchet teeth 21 inside, and the drive shaft 13 has a toggle member 20. When the ratchet teeth 21 rotates in the forward direction, the toggle member 20 will be toggle and rotate. When the ratchet teeth 21 rotates in the reverse direction, the toggle member 20 will not rotate.

[0068] This solution also provides a pressure switch, a timer, and an alarm. The pressure switch is fixedly connected to the connecting pipe 1. When the filter screen becomes clogged, the sand-proof frame 3 slides backward, squeezing the pressure switch. The alarm is mounted on the outer wall of the connecting pipe 1. The timer, flow guiding mechanism, and alarm are all connected to the controller. The alarm can be a buzzer. The timer is used to determine whether the backward movement of the sand-proof frame 3 is caused by clogging of the filter cloth 14.

[0069] The connecting pipe 1 is equipped with a slag discharge port 2. The jet pipe 12 is fixedly connected to the sand-proof frame 3, and the jet pipe 12 is aligned with the slag discharge port 2. The air outlet 11 of the cylinder body is connected to the jet pipe 12. The air intake pipe of the cylinder 6 is connected to the interior.

[0070] The magnet is fixedly connected to the connecting pipe 1. The sandproof frame 3 is made of ferromagnetic material. In the initial state, the magnet is attracted to the ferromagnetic material on the sandproof frame 3. When encountering high ambient wind pressure or increased air conditioning suction, the ferromagnetic material on the sandproof frame 3 will disconnect from the magnet. The ferromagnetic material can be made of iron.

[0071] To ensure stable reciprocating motion of the sand-proof frame 3 when encountering filter blockage, this design also includes a cam mechanism on the right side of the sand-proof frame 3. The cam mechanism comprises a cam, a contact switch, and a motor. The motor is fixed inside the connecting pipe 1 and located on the right side of the sand-proof frame 3, with the cam fixedly connected to the motor shaft. The contact switch is located on the left side of the cam, allowing the sand-proof frame 3 to contact it. Initially, the cam is not in contact with the sand-proof frame 3, and the cam's protruding part is located on the right side. When encountering filter blockage, the sand-proof frame 3 moves backward, contacting the contact switch. At this point, the controller starts the motor, causing the cam to rotate one revolution. The protruding part of the cam pushes the sand-proof frame 3 to the left, resetting it to its original position.

[0072] As attached Figure 1-4 As shown:

[0073] In specific operation, when the filter cloth 14 is clogged, the air conditioner will increase the suction force on the filter cloth 14 in order to draw in enough air. At this time, the sandproof frame 3 will be pulled by a large suction force, causing the sandproof frame 3 to move inward. When the sandproof frame 3 moves, it will drive the gear 8 to move. Because the gear 8 is meshed with the gear 8, the gear 8 will rotate forward when it moves. When the gear 8 rotates, it will cause the ratchet 21 to rotate. The rotation of the ratchet 21 will contact the actuating member 20, causing the actuating member 20 to be rotated. The rotation of the actuating member 20 will drive the drive shaft 13 to rotate. The rotation of the drive shaft 13 will pull the new filter cloth 14 out from the driven shaft 15, replacing the used filter cloth 14 in the sandproof frame 3.

[0074] During the retraction process, the piston 10 inside the cylinder moves to generate compressed gas, which enters the jet pipe 12 through the outlet 11. The jet pipe 12 sprays high-pressure gas into the slag discharge port 2 according to a preset timing or triggered by the controller, discharging the slag and particles that fall off due to the replacement of the filter cloth 14 from the slag discharge port 2, thus preventing particles from accumulating at the sliding part of the connecting pipe 1 and causing the sand-proof frame 3 to be unable to slide.

[0075] At the same time, the pressure switch will be activated, sending an electrical signal to the controller, which will then start a timer. If the sand-proof frame 3 fails to return to its original position within the set time (0.5-1 minute), it indicates that the external wind pressure may be too high, and the controller will activate the airflow control mechanism to reduce the wind pressure.

[0076] If the device fails to return to its original position after the set time (0.5-1 minute), the timer sends an electrical signal to the controller, which then activates the alarm, indicating that the device is not functioning properly.

[0077] If there are no other issues, the suction will decrease once the new filter cloth 14 is fully unfolded and covers the entire filtration area. Under the action of the first spring 22, the piston 10 pushes the push rod 9, causing the sand-proof frame 3 to return to its initial position.

[0078] The beneficial effects of this solution are as follows: 1. The automatic filter cloth replacement function reduces the need for manual intervention, improves maintenance efficiency, and reduces operating costs. 2. It ensures that the filter cloth 14 is always in optimal working condition, avoiding poor ventilation or decreased filtration efficiency due to filter cloth 14 blockage. 3. Automatic filter cloth replacement is achieved by using the air conditioning suction to cause the sand-proof frame 3 to reciprocate. This reduces the use of motors and saves costs in the long run. 4. This mechanism achieves an upgrade from "passive handling" to "proactive response" through a tiered response: first stage: automatic filter cloth replacement (to deal with blockage); second stage: airflow adjustment (to deal with wind pressure); third stage: alarm prompt (system failure). 5. This solution uses the air jet pipe 12 to clean up particles that fall from the old filter cloth 14, preventing these impurities from re-entering the sliding part of the connecting pipe 1, which would prevent the sand-proof frame 3 from sliding. The design of the slag discharge port 2 ensures that the blown-off dust and particles can be discharged in time, preventing them from accumulating inside the equipment and causing secondary pollution.
