Description

Technical Field

[0001] This invention relates to the field of grain storage technology, specifically to an automatic window opening device for grain storage. Background Technology

[0002] After harvesting, grain needs to be stored in granaries. The control of temperature and humidity in the granary is the core element to ensure the long-term storage of grain. Too high a temperature can easily cause the grain pile to heat up and become moldy, while too high a humidity can cause pests to breed. Therefore, it is necessary to achieve air circulation by opening windows regularly for ventilation.

[0003] Traditional grain warehouses mostly use manually operated steel or wooden ventilation windows. These windows require warehouse staff to operate them one by one using climbing tools, which is not only labor-intensive but also poses a risk of falling from heights. They can no longer meet the management needs of modern grain warehouses. With the development of industrial automation technology, electric window openers are gradually replacing traditional manual devices. By integrating a motor drive module and a remote control unit, they can realize the synchronous opening and closing of multiple windows, which significantly reduces labor costs and improves warehouse management efficiency.

[0004] However, electric window openers generally rely on mains power, and their mechanical transmission structure is entirely driven by electricity. In the event of a sudden power outage or circuit failure, the electric system completely fails. If severe weather such as thunderstorms or sandstorms occurs, warehouse staff may not be able to close the windows in time, which may lead to rainwater backflow causing localized dampness in the grain pile, or strong winds carrying impurities into the warehouse and contaminating the grain. In recent years, the industry has developed a window opener that integrates manual and electric operation, allowing switching to manual drive mode during power outages. Although such modifications have improved emergency operation capabilities to some extent, grain warehouse ventilation windows are relatively heavy to ensure ventilation, and their installation height generally exceeds three meters. Warehouse staff have varying levels of physical strength, and female warehouse staff need to spend extra time manually cranking the handle. Some warehouse staff are even unable to independently open and close the ventilation windows. Therefore, the existing window opening devices are still insufficient, and their versatility and convenience for warehouse staff operation still need to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic window opening device for grain warehouses, which improves the convenience and versatility of use for warehouse managers and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic window opening device for a grain warehouse, comprising an assembly plate, an assembly shell fixedly connected to the surface of the assembly plate, an adjusting rod rotatably connected to the inner wall of the assembly shell, a drive rod and two locking rods slidably connected to the inner wall of the assembly shell, and further comprising an electric control component and a manual control component for controlling the rotation of the adjusting rod respectively, a ventilation window assembly being provided at the end of the adjusting rod, the ventilation window assembly comprising a window body, a conversion box, and a control rod, the adjusting rod being drivenly connected to the control rod through the conversion box, and an identification component being provided on the window body;

[0007] The manual control component includes a mode selection component, two sets of mode locking components, and a synchronous disengagement component. Before the control lever is rotated by the drive lever, the mode selection component changes the transmission mode from the control lever to the control rod. When the mode selection component is in operation, the two sets of mode locking components automatically lock the transmission mode of the control lever after the switch through two locking rods. When the mode selection component is in operation, the synchronous disengagement component automatically releases the transmission relationship between the electric control component and the control lever.

[0008] Optionally, the electric control component includes a power drive device, which is fixedly connected to the inner wall of the assembly housing. The output end of the power drive device is fixedly connected to a drive shaft, and the end of the drive shaft is fixedly connected to a clutch one. The clutch one is engaged with a clutch two, and a splined shaft is fixedly connected to the surface of the clutch two. A connecting shaft is slidably connected to the shaft wall of the splined shaft via a spline. A support block is fixedly connected to the inner wall of the assembly housing, and a conversion box two and a conversion box three are fixedly connected to the top surface of the support block. The connecting shaft and the control rod are connected by transmission through the conversion box two.

[0009] Optionally, the mode selection component includes a switching plate, which is slidably connected to the inner wall of the assembly housing. An internal gear ring is rotatably connected to the inner wall of the switching plate. The surface of the internal gear ring is fixedly connected to the drive rod via a connecting bracket. A bevel gear is fixedly connected to the arm of the drive rod. Two mounting blocks are fixedly connected to the surface of the switching plate. A mounting plate is fixedly connected to the opposite sides of the two mounting blocks. A double-sided bevel gear is rotatably connected to the surface of the mounting plate. The double-sided bevel gear meshes with the first bevel gear. Two limiting rods are slidably connected to the inner wall of the mounting plate. The ends of the two limiting rods are fixedly connected to the inner wall of the assembly housing. Two limiting springs are sleeved on the rod walls of the two limiting rods. The two ends of the four limiting springs are fixedly connected to the inner wall of the assembly housing and the side wall of the switching plate, respectively.

[0010] Optionally, the mode selection component includes a shaft, on which a bevel gear II and a gear are fixedly connected. The teeth of the gear are adapted to the teeth of the internal gear ring, and the teeth of the bevel gear II are adapted to the teeth of the double-sided bevel gear. The shaft and the control rod are connected by a conversion box III.

[0011] Optionally, the mode locking component includes a pressing rod. The surface of the assembled housing has a groove through which the locking rod passes and is slidably connected. Locking slots are provided on both the upper and lower sides of the groove. The pressing rod is slidably connected to the inner wall of the locking rod. A pressure spring is fixedly connected to the end of the pressing rod. The end of the pressure spring is fixedly connected to the inner wall of the locking rod. The arm of the pressing rod is hinged to two locking blocks by a rod member. Both locking blocks are slidably connected to the inner wall of the locking rod. The groove wall has locking interfaces corresponding to the two locking blocks.

[0012] Optionally, the synchronous disengagement component includes two hinged rods, the far ends of which are rotatably connected to the surface of the mounting plate, and the near ends of which are rotatably connected to a connecting ring on a common fixed axis, the inner wall of which is rotatably connected to the outer wall of the second clutch.

[0013] Optionally, a rotating wheel is fixedly connected to the end of the drive rod, and the surface of the rotating wheel is provided with anti-slip texture.

[0014] Optionally, rubber gaskets are fixedly connected to both sides of the assembled housing, and the two rubber gaskets are respectively adapted to the size of the two sliding grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] I. This invention integrates both electric and manual control modes, so that warehouse staff can control the status of the window even in extreme situations such as power outages. In addition, under the manual operation function, two additional modes, fast mode and labor-saving mode, are provided for warehouse staff to switch as needed, thereby improving the convenience of warehouse staff operation and the applicability of this device.

[0017] At the same time, regardless of which operating mode the warehouse manager chooses, when controlling the window, the rotating wheel is rotated in the same direction, which greatly improves the ease of operation and makes the device more standardized. After adjusting the window in the power failure state, the pressing rod can be pressed again to return the mounting plate to the initial position. When the current of the power drive device is restored, the window can still be automatically controlled normally through the power drive device.

[0018] Second, this invention allows the device to automatically lock after the warehouse manager selects the operating mode, eliminating the need for the warehouse manager to constantly overcome the spring force to adjust the opening and closing of the window, thus further improving ease of use. The two operating modes provided by this device also allow the warehouse manager to select only once during actual use, directly switching from electric drive to fast mode or to labor-saving mode. Compared with traditional switching methods, there is no need for secondary switching, making it convenient to use.

[0019] Third, this invention allows warehouse staff to move the connecting ring axially towards the mounting plate by pulling it with two hinged rods, regardless of whether they choose the fast or labor-saving mode. This disengages clutch two from clutch one, allowing the warehouse staff to simultaneously disconnect the transmission connection between the window and the power drive device while selecting between the fast and labor-saving modes. This significantly reduces the damage rate and resistance of the device in manual operation mode, further enhancing its practicality and convenience. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1 to 8 This invention provides an automatic window opening device for a grain warehouse, comprising an assembly plate 1, an assembly shell 2 fixedly connected to the surface of the assembly plate 1, an adjusting rod 3 rotatably connected to the inner wall of the assembly shell 2, a drive rod 4 and two locking rods 5 slidably connected to the inner wall of the assembly shell 2, and an electric control component and a manual control component for controlling the rotation of the adjusting rod 3 respectively. A ventilation window assembly is provided at the end of the adjusting rod 3, comprising a window body 6, a conversion box 7, and a control rod 8. The adjusting rod 3 is connected to the control rod 8 via the conversion box 7. An identification component, specifically a humidity detector, is provided on the window body 6. The identification component identifies the humidity of the external environment of the grain warehouse to determine whether the window body 6 needs to be opened or closed. If opening or closing is required, a corresponding command signal is sent to the electric control component, which drives the adjusting rod 3 to rotate, thereby causing the window body 6 to deflect through the rotation of the control rod 8, thus opening or closing the ventilation function.

[0031] The manual control unit includes a mode selection unit, two sets of mode locking units, and a synchronous disengagement unit. Before the control lever 3 is rotated by the drive lever 4, the mode selection unit changes the transmission mode from the control lever 3 to the control lever 4. When the mode selection unit is in operation, the two sets of mode locking units automatically lock the transmission mode of the control lever 3 after the switch through two locking levers 5. When the mode selection unit is in operation, the transmission relationship between the electric control unit and the control lever 3 is automatically released by the synchronous disengagement unit.

[0032] The electric control component includes a power drive device 9, which is fixedly connected to the inner wall of the assembly housing 2. The output end of the power drive device 9 is fixedly connected to a drive shaft 10. The end of the drive shaft 10 is fixedly connected to a clutch 11. The clutch 11 is engaged with a clutch 12. The surface of the clutch 12 is fixedly connected to a splined shaft 13. The shaft wall of the splined shaft 13 is slidably connected to a connecting shaft 14 via a spline. The inner wall of the assembly housing 2 is fixedly connected to a support block 15. The top surface of the support block 15 is fixedly connected to a conversion box 16 and a conversion box 17. The connecting shaft 14 and the control rod 3 are connected by transmission through the conversion box 16.

[0033] More specifically, in this embodiment: the start of the power drive device 9 will drive the drive shaft 10 to rotate, and then through the cooperation of clutch one 11 and clutch two 12, the spline shaft 13 will rotate, thus causing the connecting shaft 14 to rotate. Through the setting of the conversion box two 16, the control rod 3 can be rotated, thus realizing the automatic opening or closing function of the window 6. When the identification component detects that the external humidity is high, it sends a command signal to the power drive device 9 to close the window 6.

[0034] In the above process, the function of both conversion box 1 7 and conversion box 2 16 is to adjust the rotation drive direction by 90°. Their internal structure can adopt the mechanical cooperation of two bevel gears or the cooperation structure of worm gear. Since such conversion of driving force direction is common in the prior art and there are already complete sets of components on the market, this application only utilizes its function and will not elaborate on the specific principle. The same applies to conversion box 3 17.

[0035] Example 2, based on the above examples:

[0036] Please see Figures 2 to 4 , Figure 6 The mode selection component includes a switching plate 18, which is slidably connected to the inner wall of the assembly housing 2. An internal gear ring 19 is rotatably connected to the inner wall of the switching plate 18. The surface of the internal gear ring 19 is fixedly connected to the drive rod 4 via a connecting bracket 20. A bevel gear 21 is fixedly connected to the arm of the drive rod 4. Two mounting blocks 22 are fixedly connected to the surface of the switching plate 18. A mounting plate 23 is fixedly connected to the opposite sides of the two mounting blocks 22. A double-sided bevel gear 24 is rotatably connected to the surface of the mounting plate 23. The double-sided bevel gear 24 meshes with the bevel gear 21. Two limiting rods 25 are slidably connected to the inner wall of the assembly housing 2. The ends of the two limiting rods 25 are fixedly connected to the inner wall of the assembly housing 2. Two limiting springs 26 are sleeved on the rod walls of the two limiting rods 25. The two ends of the four limiting springs 26 are fixedly connected to the inner wall of the assembly housing 2 and the side wall of the switching plate 18, respectively.

[0037] Shaft 27 has bevel gear 28 and gear 29 fixedly connected to its shaft wall. The teeth of gear 29 are compatible with the teeth of internal gear ring 19, and the teeth of bevel gear 28 are compatible with the teeth of double-sided bevel gear 24. The shaft 27 is connected to the control rod 3 via conversion box 3 17. The end of drive rod 4 is fixedly connected to a rotating wheel 36, and the surface of the rotating wheel 36 is provided with anti-slip texture.

[0038] More specifically, in this embodiment: when an extreme situation such as a power outage occurs, the power drive device 9 loses power supply. At this time, the warehouse manager can come to the assembly shell 2 and select to raise or lower the switching plate 18 to switch the internal structure of the assembly shell 2 to two transmission modes respectively. If the current situation is not an emergency, or if the warehouse manager has less strength, the height of the switching plate 18 can be lowered. During this process, the limit spring 26 deforms. Through the descent of the switching plate 18, the drive rod 4, the bevel gear 21, the double-sided bevel gear 24, and the internal gear ring 19 are all driven synchronously. The mechanism descends until the double-sided bevel gear 24 meshes with the second bevel gear 28. At this point, the mode locking component locks itself in the current state, and the synchronous disengagement component promptly releases the transmission relationship between the electric control component and the control lever 3. The warehouse manager then rotates the rotating wheel 36, causing the drive lever 4 to rotate. In this state, the drive lever 4 drives the first bevel gear 21 to rotate. Subsequently, through the transmission of the double-sided bevel gear 24 and the second bevel gear 28, the shaft 27 rotates in the same direction as the drive lever 4. This, in turn, causes the control lever 3 to rotate through the conversion box 3 17. In this way, the state of the window 6 can be controlled.

[0039] If the current natural conditions are in an emergency such as heavy rain or showers, or if the warehouse manager is not weak, the height of the switching plate 18 can be raised. By raising the switching plate 18, the teeth of the internal gear ring 19 and the gear 29 can mesh, and the transmission path from the first bevel gear 21 to the second bevel gear 28 cannot be connected. At this time, the warehouse manager can still make the shaft 27 rotate in the same direction as the drive rod 4 by rotating the rotating wheel 36. In this way, the state of the window 6 can also be controlled.

[0040] As mentioned above, this device integrates both electric and manual control modes. In addition, in manual operation mode, it provides two additional modes, a fast mode and a labor-saving mode, for warehouse staff to switch between as needed, thereby improving the convenience of operation for warehouse staff and the applicability of this device.

[0041] At the same time, regardless of which operating mode the warehouse manager chooses, when controlling window 6, the mechanical component in the same position is rotated in the same direction, which greatly improves the ease of operation and makes the device more standardized.

[0042] Example 3, based on the above examples:

[0043] Please see Figure 2 , Figure 3 , Figure 7 and Figure 8 The mode locking component includes: a pressing rod 30; a groove is provided on the surface of the assembly housing 2 for the locking rod 5 to pass through and slide in connection with it; locking grooves 31 are provided on both the upper and lower sides of the groove; the pressing rod 30 is slidably connected to the inner wall of the locking rod 5; a pressure spring 32 is fixedly connected to the end of the pressing rod 30; the end of the pressure spring 32 is fixedly connected to the inner wall of the locking rod 5; two locking blocks 33 are hinged to the arm of the pressing rod 30 through a rod member; both locking blocks 33 are slidably connected to the inner wall of the locking rod 5; and the groove wall of the groove is provided with locking interfaces corresponding to the two locking blocks 33.

[0044] More specifically, in this embodiment: when the warehouse manager operates, he / she can hold the locking lever 5 with both hands and press the pressing lever 30 with his / her fingers. Through the relative sliding between the pressing lever 30 and the locking lever 5, the pressure spring 32 is compressed during this process, thereby pulling the two locking blocks 33 to slide through the lever, so that the two locking blocks 33 simultaneously disengage from the locking interface, so that the locking lever 5 loses the limitation of the slide groove. At this time, the warehouse manager can move the locking lever 5 downward or upward. Taking upward movement as an example, when it moves to the upper locking groove group 31, the pressing lever 30 is released. Under the elastic reset action of the pressure spring 32, the two locking blocks 33 pop out to the locking groove group 31. In this way, the locking lever 5 cannot descend and reset on its own through the locking groove group 31, thereby completing the self-locking of the current position.

[0045] The above method allows the device to automatically lock after the warehouse manager selects the start-up mode, eliminating the need for the warehouse manager to constantly overcome the spring force, thus further improving ease of use. The two operating modes provided by this device also allow the warehouse manager to select only once, directly switching from electric drive to fast mode or labor-saving mode. Compared to traditional switching methods, this device does not require secondary switching, making it convenient to use.

[0046] Example 4, based on the above examples:

[0047] Please see Figures 3 to 5 The synchronous disengagement component includes two hinge rods 34, the far ends of which are rotatably connected to the surface of the mounting plate 23, and the near ends of which are rotatably connected to a connecting ring 35 on a common fixed axis. The inner wall of the connecting ring 35 is rotatably connected to the outer wall of the clutch 12.

[0048] More specifically, in this embodiment: when the warehouse manager makes adjustments, the mounting plate 23 will move upward or downward. Regardless of the direction of movement, the two hinge rods 34 will move synchronously, causing the far ends of the two hinge rods 34 to rotate relative to the mounting plate 23. As the horizontal height of this area changes, the connecting ring 35 will be pulled axially towards the mounting plate 23 through the near ends of the two hinge rods 34. During this movement, the clutch 2 12 will disengage from the clutch 1 11, and the spline shaft 13 will slide along the inner wall of the connecting shaft 14. In this way, in the operation mode where the warehouse manager drives the manual control component, the transmission connection between the window 6 and the power drive device 9 can be automatically released. This can significantly reduce the damage rate of this device in the manual operation mode.

[0049] Working principle: When the automatic window opening device of the grain warehouse is in use, the power drive device 9 is started, which drives the drive shaft 10 to rotate, thereby controlling the state of the window 6. When the window 6 is open, if the recognition component detects that the external humidity is high, it determines that the moisture is likely to have an adverse effect on the grain in the grain warehouse. At this time, it sends a command signal to the power drive device 9 to close the window 6.

[0050] In extreme situations such as power outages, the power drive device 9 loses its power supply. To ensure that the grain pile in the grain warehouse remains moist, the warehouse manager can come to the assembly shell 2. If the current situation is not an emergency, or if the warehouse manager is not strong enough, he can hold the locking rod 5 with both hands and press the pressing rod 30 with his fingers. Through the process of the two locking blocks 33 disengaging from the locking interface, the locking rod 5 loses the limit of the slide groove. Then, through the locking rod 5, the height of the switching plate 18 is lowered. As the switching plate 18 descends, the drive rod 4, bevel gear 1 21, double-sided bevel gear 24, and internal gear ring 19 all descend synchronously until the double-sided bevel gear 24 meshes with the bevel gear 28. Then, the pressing rod 30 is released. Under the elastic reset action of the pressure spring 32, the two locking blocks 33 pop out to the locking groove group 31, thus completing the self-locking of the current position.

[0051] The warehouse keeper can then rotate the rotating wheel 36, which, through the transmission of the double-sided bevel gear 24 and bevel gear 28, causes the shaft 27 to rotate in the same direction as the drive rod 4. This, in turn, causes the control rod 3 to rotate via the conversion box 17, thus controlling the state of the window 6. In emergency situations such as heavy rain or showers, or when the warehouse keeper is not physically weak, the height of the switching plate 18 can be raised. Raising the switching plate 18 allows the internal gear ring 19 to mesh with the teeth of the gear 29, while the transmission path from bevel gear 21 to bevel gear 28 is blocked. At this point, the warehouse keeper can still rotate the rotating wheel 36. This allows the shaft 27 to rotate in the same direction as the drive rod 4, thus controlling the state of the window 6. This combines both electric and manual control modes, preventing situations where the window 6 cannot be controlled due to power outages or other special circumstances. In manual operation mode, two additional modes, a fast mode and a labor-saving mode, are provided for warehouse staff to switch between as needed, improving the convenience of operation and the applicability of the device. Regardless of which operation mode the warehouse staff chooses, when controlling the window 6, the rotating wheel 36 is driven to rotate in the same direction, greatly improving the ease of operation and making the device more standardized.

[0052] During the manual mode selection process, regardless of whether the mounting plate 23 moves upward or downward, the two hinge rods 34 can pull the connecting ring 35 axially towards the mounting plate 23, causing the clutch 2 12 to disengage from the clutch 1 11. This allows the warehouse manager to simultaneously disconnect the transmission connection between the window 6 and the power drive device 9 while selecting between the fast and labor-saving modes, significantly reducing the damage rate of the device in manual operation mode. After adjusting the window 6 in a power outage state, the warehouse manager can press the pressing rod 30 again to return the mounting plate 23 to its initial position. In this state, the clutch 2 12 and the clutch 1 11 remain engaged. When the current to the power drive device 9 is restored, the window 6 can still be automatically controlled normally through the power drive device 9.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
