Description

Technical Field

[0001] The present invention relates to the technical field of grain depot thermal insulation windows, and more specifically, to a grain depot thermal insulation window with an airbag type thermal insulation structure. Background Art

[0002] In grain storage, grain storage thermal insulation windows are of great significance to grain storage environment control, but there are many problems with existing grain storage thermal insulation windows:

[0003] 1. Poor connection and sealing. The window and window frame of traditional thermal insulation windows are not firmly connected. They are usually connected by ordinary hinges or latches, which are easily loosened by temperature changes, wind force, and air pressure in the warehouse. After loosening, the seal fails, and the outside air enters, causing the temperature in the warehouse to be unstable, increasing the temperature control cost, and also causing the risk of food mold and deterioration, affecting the quality and storage period of food;

[0004] 2. Functional defects of blinds: When traditional blinds are used for grain storage insulation windows, the insulation performance is poor. It is difficult to block cold air with only the blind material. When adjusting the position of the blind frame, due to the lack of a limit stability structure, it is easy to shake and cannot be accurately positioned. It is not possible to flexibly adjust lighting and ventilation as needed. For example, it is difficult to control the opening angle during ventilation, and the ventilation effect is poor;

[0005] 3. Imprecise ventilation control: Traditional grain warehouse ventilation windows lack a mechanism for accurately adjusting ventilation volume. Most of them are simple switch operations and cannot be adjusted in real time according to the temperature, humidity, air quality, etc. in the warehouse. When the humidity is high and ventilation is needed, the ventilation volume may be insufficient. Sometimes, excessive ventilation will cause the temperature in the warehouse to be too low, affecting the stability of the grain storage environment and threatening the quality and safety of grain.

[0006] 4. The overall structure is unstable: the traditional window frame structure has low strength and is difficult to cope with severe weather such as strong winds. It is easy to deform and damage. Some airbag insulation windows are difficult to inflate and cannot keep warm in time. In addition, the insulation windows are not installed firmly and are easy to loosen and fall off due to the air pressure in the warehouse or external forces, affecting the safety and reliability of use, increasing maintenance costs and safety hazards.

The suction ports of the two air pumps are connected to the vacuum suction cups, and the suction ports of the two air pumps are also connected to a one-way air inlet valve.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention effectively solves the problem that the connection between the outer window body and the window frame of the traditional window is not firm and easy to loosen by setting a self-locking reinforcement mechanism linked with the handle. When the handle is turned, the handle drives the active bevel gear to rotate, and the active bevel gear meshes with the driven bevel gear, thereby driving the one-way screw to rotate. The rotation of the one-way screw causes the locking plate to slide along the outer window body and finally get stuck in the locking groove in the window frame. This structural design enables the outer window and the window frame to be locked quickly and stably, greatly improving the overall stability of the grain depot insulation window. At the same time, the tight connection effectively reduces the heat exchange between the outside air and the air inside the grain depot. The temperature in the grain depot is kept constant, creating a good environment for grain storage. Another user holds the handle and pushes it. The hook-shaped card block on the elastic lock tongue moves with the handle and is inserted into the card slot on the window frame. This solution not only solves the problem of complex structure and inconvenient operation of traditional window locks, but also effectively prevents the outer window from being opened by mistake, so that the thermal insulation window has the function of self-locking when closing the window. Moreover, the design of the elastic lock tongue makes it possible to easily open the outer window by pressing with one hand when unlocking, which reduces the difficulty of operation, improves the flexibility of the use of the thermal insulation window, and facilitates the staff to perform daily ventilation and other operations on the grain depot.

[0021] 2. The present invention significantly improves the thermal insulation and ventilation performance of the thermal insulation window through the coordinated work of multiple components such as the louver frame, louver plates, expansion bags, inner window bodies and ventilation components. The motor on the louver frame is started, and the motor output shaft drives the louver plates connected thereto to rotate. Through the linkage of the first chain belt, a group of louver plates rotate synchronously, and the louver plate angles can be flexibly adjusted to meet ventilation and lighting requirements. When the temperature is low or better insulation is required, the pneumatic booster system inflates the expansion bags on both sides of the louver plates. After the expansion bags are inflated, they can effectively block the entry of cold air from the outside, thereby enhancing the insulation effect and reducing the heat dissipation in the grain depot. The loss helps to extend the storage period of grain and solves the problem of insufficient thermal insulation performance of traditional shutters. When the position of the inner window needs to be adjusted, the inner window slides along the second T-shaped guide rod on the window frame, and the second limit spring provides elastic force on both sides of it to enable it to stay stably in the required position. The staff can slide the inner window to the appropriate position according to the actual situation in the grain depot, such as when the humidity is high and ventilation needs to be strengthened. Moreover, when the expansion bag expands, the position of the inner window can be changed automatically, and then cooperate with the shutter frame to realize the bipolar telescopic adjustment of the thickness of the thermal insulation layer of the window, thereby further optimizing the thermal insulation effect.

[0022] 3. The ventilation component in the inner window of the present invention can accurately control the ventilation area, rotate the driving shaft on the window frame, and the linkage bevel gear on the driving shaft engages with the linkage bevel gear on the hinge shaft, driving the hinge shaft to rotate, and then the square groove in the driving shaft cooperates with the square shaft on the inner window, driving the square shaft to rotate, and the square shaft drives the valve column to rotate. Through the second chain belt, a group of valve columns rotate synchronously, so that the relative position of the ventilation area on the valve column and the ventilation strip hole changes, thereby realizing the adjustment of the ventilation area. This component solves the problem that the traditional grain depot ventilation windows cannot accurately control the ventilation volume. It can accurately adjust the ventilation area according to the real-time data of temperature, humidity, air quality, etc. in the grain depot, to ensure smooth air circulation in the grain depot, while avoiding the impact of excessive or insufficient ventilation on grain storage, effectively maintaining a good storage environment in the grain depot, and ensuring the quality and safety of grain.

[0023] 4. In the present invention, the air pump in the pneumatic booster system is started, and the air pump inflates the sealing ring bag through the air guide hose. After the sealing ring bag is inflated, it is tightly fitted to the contact part of the window frame with the outside world, thereby increasing the connection area between the window frame and the wall of the grain depot, thereby improving the connection stability, effectively preventing the infiltration of outside air, and improving the thermal insulation performance of the thermal insulation window. In the telescopic reinforcement component, the bidirectional screw rotates, the driving block drives the support arm to extend the reinforcement plate, and the reinforcement bag is inflated, which enhances the overall structural strength of the window frame, so that it can better cope with severe weather, such as maintaining stability in windy weather, extending the service life of the thermal insulation window, and providing more reliable protection for the grain depot. The air pump of the pneumatic booster system also allows the vacuum suction cup to be adsorbed on the wall of the grain depot through the suction port, further fixing the outer window body and improving the connection strength between the outer window body and the grain depot.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 12 As shown, the present invention provides a grain storage thermal insulation window with an airbag thermal insulation structure, comprising a window frame 1 and an outer window body 2;

[0039] The outer window 2 is made of tempered glass;

[0040] A positioning ring plate 3 is provided on the window frame 1, and the outer window body 2 is fixedly connected to the window frame 1 through a hinge shaft 23. A handle 4 is rotatably mounted on the outer window body 2, and a self-locking reinforcement mechanism linked to the handle 4 is provided between the window frame 1 and the outer window 2;

[0041] The self-locking reinforcement mechanism includes two lock slots 13 provided in the window frame 1, two symmetrically arranged locking plates 14 adapted to the lock slots 13 are slidably connected to the outer window body 2, two one-way screws 15 are rotatably installed on the outer window body 2, and the two one-way screws 15 are respectively connected to the two locking plates 14 in a transmission manner, and an active bevel gear is installed on the handle 4, and the tail ends of the two one-way screws 15 are fixedly installed with driven bevel gears, and the two driven bevel gears are both connected to the active bevel gear in a transmission manner;

[0042] When the handle 4 is turned, the handle 4 drives the active bevel gear to rotate, the active bevel gear meshes with the driven bevel gear, and then drives the one-way screw 15 to rotate. The rotation of the one-way screw 15 causes the locking plate 14 to slide along the outer window body 2 and finally get stuck in the locking groove 13 in the window frame 1;

[0043] This structure solves the technical problem that the connection between the outer window 2 and the window frame 1 of the traditional window is not firm and easy to loosen. By simply turning the handle 4, the outer window 2 and the window frame 1 are quickly and stably locked, which greatly improves the overall stability and sealing of the grain storage insulation window, effectively reduces the heat exchange between the outside air and the air inside the grain storage, better maintains the constant temperature in the grain storage, and creates a good environment for grain storage;

[0044] The self-locking reinforcement mechanism includes a slot 16 provided on the window frame 1, an elastic locking tongue 17 is fixedly mounted on the handle 4, a grip 18 is mounted between the handle 4 and the elastic locking tongue 17, and a barb-shaped block 19 adapted to the slot 16 is fixedly mounted on the elastic locking tongue 17;

[0045] The user holds the grip 18 and pushes the handle 4. At this time, the barbed block 19 on the elastic lock tongue 17 moves with the handle 4 and is inserted into the slot 16 on the window frame 1. This solution solves the problem of complex structure and inconvenient operation of traditional window locks.

[0046] At the same time, through the above-mentioned structural setting, the probability of the outer window 2 being opened by mistake can be effectively avoided and the thermal insulation window has a self-locking function when the window is closed;

[0047] At the same time, the design of the elastic lock tongue 17 allows the outer window 2 to be easily opened by pressing the elastic lock tongue 17 with one hand when unlocking, which reduces the difficulty of operation, improves the flexibility of using the thermal insulation window, and facilitates the staff to perform daily ventilation operations on the grain depot;

[0048] A louver frame 5 is slidably installed in the outer window body 2, and a set of first elastic limiting members 6 is installed between the window frame 1 and the louver frame 5;

[0049] The first elastic limiting member 6 comprises a first T-shaped guide rod mounted on the window frame 1, the first T-shaped guide rod is slidably connected to the shutter frame 5, and first limiting springs are sleeved on the first T-shaped guide rod and at positions corresponding to both sides of the shutter frame 5;

[0050] When the position of the shutter frame 5 needs to be adjusted, the shutter frame 5 slides along the first T-shaped guide rod on the window frame 1, and the first limit spring plays a buffering and positioning role on both sides of the shutter frame 5;

[0051] This structure solves the problem that the shutter frame 5 is easy to shake and difficult to accurately position when adjusted, and can flexibly adjust the position of the shutter frame 5 according to actual needs. For example, when more lighting is needed, the shutter frame 5 can be slid to a suitable position, and when ventilation is needed, it can be adjusted to a corresponding opening angle;

[0052] Moreover, the buffering effect of the first limit spring protects the shutter frame 5, reduces the wear caused by frequent sliding, prolongs the service life of the shutter frame 5, and also ensures the stability of the shutter frame 5 during the adjustment process, thereby improving the performance of the grain storage insulation window;

[0053] At the same time, when the expansion bags 8 on both sides of the shutter plate 7 expand simultaneously, the position of the shutter frame 5 can be changed automatically. After the position of the shutter frame 5 is changed automatically, the total thickness formed by the two expansion bags 8 is changed, thereby adjusting the thickness of the heat preservation layer in the window and the heat preservation strength and effect of the device;

[0054] A group of louver plates 7 are rotatably mounted on the louver frame 5, and the group of louver plates 7 are linked by a first chain belt. A motor is mounted on the louver frame 5, and the output shaft end of the motor is fixedly connected to the louver plates 7. Expansion bags 8 are fixedly mounted on both sides of the louver plates 7.

[0055] Start the motor, the motor output shaft drives the louver plates 7 connected thereto to rotate, and through the linkage of the first chain belt, a group of louver plates 7 rotate synchronously, and the angle of the louver plates 7 is adjusted. At the same time, when the temperature is low or better heat preservation is required, the expansion bag 8 is inflated and bulged;

[0056] This design solves the problem of insufficient thermal insulation performance of traditional blinds;

[0057] By flexibly adjusting the angle of the louver 7, the ventilation demand can be met and the amount of light can be controlled. After the expansion bag 8 is inflated, it can effectively block the entry of cold air from the outside, enhance the insulation effect, reduce the heat loss in the grain depot, provide a more suitable temperature environment for grain storage, and help to extend the storage period of grain.

[0058] The outer window 2 is provided with a telescopic slot 9, an inner window 10 is slidably installed in the telescopic slot 9, and a set of second elastic limiting members 11 are installed between the inner window 10 and the window frame 1;

[0059] The second elastic limiting member 11 comprises a second T-shaped guide rod mounted on the window frame 1, the second T-shaped guide rod is slidably connected to the inner window body 10, and second limiting springs are sleeved on the second T-shaped guide rod and at positions corresponding to both sides of the inner window body 10;

[0060] When the position of the inner window 10 is to be adjusted, the inner window 10 slides along the second T-shaped guide rod on the window frame 1, and the second limit spring provides elastic force on both sides thereof, so that it can stably stay in the desired position. This structure solves the problem of difficult adjustment and inaccurate positioning of the inner window 10; the staff can slide the inner window 10 to a suitable position according to the actual situation in the grain depot, such as when the humidity is high and ventilation needs to be strengthened. The presence of the second limit spring not only facilitates the adjustment of the inner window 10, but also plays a buffering and protective role for the inner window 10, avoiding damage to the inner window 10 due to collision during the sliding process, ensuring the normal use of the inner window 10, and improving the overall reliability of the grain depot insulation window;

[0061] At the same time, when the expansion bag 8 is expanded, the position of the inner window 10 can be changed automatically, and then cooperate with the shutter frame 5 to achieve the double-stage telescopic adjustment of the thickness of the thermal insulation layer of the window;

[0062] A ventilation component is provided in the inner window 10, and the ventilation component controls the ventilation area of ​​the inner window 10;

[0063] The ventilation assembly includes a group of ventilation chambers distributed in a linear array and opened in the inner window body 10. Ventilation strip holes 20 communicating with the ventilation chambers are opened on both sides of the inner window body 10 and at positions corresponding to each ventilation chamber. A valve column 21 is rotatably installed in each ventilation chamber. The cross sections of the ventilation chamber and the valve column 21 are both circular. A linkage assembly for driving the valve column 21 to rotate is provided on the window frame 1. A ventilation area adapted to the ventilation strip holes 20 is provided on the valve column 21, and ventilation holes 34 are evenly distributed on the ventilation area.

[0064] The linkage assembly includes a driving shaft 22 rotatably connected to the window frame 1, and a linkage bevel gear is installed on the driving shaft 22 and the hinge shaft 23, and the two linkage bevel gears are meshed with each other. A square groove with an opening at the tail end is fixedly opened inside the driving shaft 22, and a square shaft 24 is rotatably installed on the inner window body 10. The square shaft 24 can slide in the axial direction and is fixed in the square groove in the circumferential direction. The cross-sections of the square shaft 24 and the square groove are both regular polygons. Tail bevel gears are installed on the square shaft 24 and a valve column 21, and the two tail bevel gears are meshed with each other. A group of valve columns 21 are linked through a second chain belt.

[0065] The driving shaft 22 on the window frame 1 is rotated, and the linkage bevel teeth on the driving shaft 22 are meshed with the linkage bevel teeth on the hinge shaft 23, driving the hinge shaft 23 to rotate, and then the inner square groove of the driving shaft 22 cooperates with the square shaft 24 on the inner window body 10, driving the square shaft 24 to rotate, and the square shaft 24 drives the valve column 21 to rotate. Through the second chain belt, a group of valve columns 21 rotate synchronously, so that the relative position of the ventilation area on the valve column 21 and the ventilation strip hole 20 changes, thereby realizing the adjustment of the ventilation area.

[0066] This solution solves the problem that traditional grain warehouse ventilation windows cannot accurately control the ventilation volume. It can accurately adjust the ventilation area according to real-time data such as temperature, humidity, and air quality in the grain warehouse to ensure smooth air circulation in the grain warehouse. At the same time, it avoids the impact of excessive or insufficient ventilation on grain storage, effectively maintains a good storage environment in the grain warehouse, and ensures the quality and safety of grain.

[0067] The valve column 21 is made of transparent glass;

[0068] A sealing ring bag 12 is installed on the outer periphery of the window frame 1 and at a position corresponding to the rear side of the positioning ring plate 3. A telescopic reinforcement component is provided on both sides of the window frame 1. The window frame 1 is provided with a pneumatic booster system for supplying air to the expansion bag 8 and the sealing ring bag 12.

[0069] The telescopic reinforcement component includes a reinforcement plate 25 and a bidirectional screw rod 26 rotatably connected to the inner window 10, the bidirectional screw rod 26 is respectively provided with a positive thread segment and a negative thread segment, and a driving block 27 is installed on the positive thread segment and the negative thread segment for transmission, an arm 28 is hinged between the reinforcement plate 25 and the two driving blocks 27, and an expandable reinforcement bag 29 is provided on the reinforcement plate 25.

[0070] The air pump 30 in the pneumatic booster system is started, and the air pump 30 inflates the sealing ring bag 12 and the reinforcement bag 29 through the air guide hose. After the sealing ring bag 12 is inflated, on the one hand, it is closely attached to the contact part of the window frame 1 with the outside world, and on the other hand, the air inflated sealing ring bag 12 increases the connection area between the window frame 1 and the wall of the grain depot, thereby improving the connection stability between the window frame 1 and the wall of the grain depot;

[0071] In the telescopic reinforcement component, the bidirectional screw rod 26 rotates, the driving block 27 drives the support arm 28 to extend the reinforcement plate 25, and the reinforcement bag 29 is inflated. This structure solves the problem of poor sealing and insufficient structural strength of the window frame 1; the sealing ring bag 12 effectively prevents the infiltration of external air and improves the thermal insulation performance of the thermal insulation window; the telescopic reinforcement component enhances the overall structural strength of the window frame 1, so that it can better cope with bad weather, such as maintaining stability in windy weather, extending the service life of the thermal insulation window, and providing more reliable protection for the grain depot;

[0072] By setting the telescopic reinforcement component, the connection area between the window frame 1 and the grain depot wall is increased from the physical level, thereby improving the connection stability between the window frame 1 and the grain depot wall;

[0073] By setting the air-inflating structure of the reinforcement bag 29, the gap rate between the reinforcement plate 25 and the wall of the grain depot is reduced and the connection tightness between the reinforcement plate 25 and the wall of the grain depot is improved;

[0074] The pneumatic booster system includes two air pumps 30 installed on the end surface of the window frame 1. The air outlet ports of the two air pumps 30 are connected to an air hose. The inner cavity of the reinforcement bag 29, the inner cavity of the sealing ring bag 12 and the inner cavity of the expansion bag 8 are all connected to the air hose.

[0075] The self-locking reinforcement mechanism also includes two suction seats 31 fixed on the outer window 2, and a group of vacuum suction cups 32 are installed on the two suction seats 31. The suction ports of the two air pumps 30 are connected to the vacuum suction cups 32, and the suction ports of the two air pumps 30 are also connected to a one-way air inlet valve 33.

[0076] When the air pump 30 is working, on the one hand, air is supplied to the reinforcement bag 29, the sealing ring bag 12 and the expansion bag 8 through the air guide hose to ensure that these air bag structures function normally and maintain a good insulation and reinforcement effect. On the other hand, the air pump 30 makes the vacuum suction cup 32 adsorb on the wall of the grain depot through the suction port, thereby further fixing the outer window 2 and improving the connection strength between the outer window 2 and the grain depot, thereby reducing the damage or opening rate of the outer window 2 caused by the internal pressure of the grain depot;

[0077] The one-way air inlet valve 33 ensures the one-way flow of gas. This solution solves the problems of difficulty in inflating the airbag and loose installation of the thermal insulation window, ensures the stable operation of the entire thermal insulation window system, improves the installation stability and working reliability of the thermal insulation window, enables the thermal insulation window to better adapt to the use environment of the grain warehouse, and provides better protection for grain storage.

[0078] Working principle and use process of the present invention: The grain storage insulation window with airbag insulation structure shows unique working principle and process in many aspects:

[0079] In terms of self-locking reinforcement, it has two functions. The first is to rotate the handle 4 on the outer window body 2 to drive the active bevel gear to rotate, and the one-way screw 15 is rotated by meshing with the driven bevel gear, so that the locking plate 14 is inserted into the lock groove 13 of the window frame 1, which solves the problem that the outer window body 2 and the window frame 1 of the traditional window are not firmly connected and easy to loosen, and improves the stability and sealing. The second is that the user holds the handle 18 and pushes the handle 4, so that the hook-shaped block 19 on the elastic lock tongue 17 is inserted into the slot 16 of the window frame 1. It is easy to operate and also has the functions of self-locking and anti-misopening of the window. When unlocking, just press the elastic lock tongue 17.

[0080] When adjusting the position of the louver frame 5, the louver frame 5 slides along the first T-shaped guide rod on the window frame 1, and the first limit spring plays a role of buffering and positioning, avoiding the problem of shaking and difficulty in accurate positioning during adjustment. When the expansion bags 8 on both sides of the louver plate 7 expand at the same time, the position of the louver frame 5 will be driven to change to adjust the thickness and effect of the thermal insulation layer. The motor on the louver frame 5 can be started to make a group of louver plates 7 rotate synchronously to adjust the angle through the first chain belt linkage to meet the ventilation and lighting requirements. When the temperature is low or better insulation is required, the pneumatic booster system inflates the expansion bag 8 to enhance insulation.

[0081] When adjusting the position of the inner window 10, the inner window 10 slides along the second T-shaped guide rod, and the second limit spring provides elastic force to make it stay stably. It can be flexibly adjusted according to the actual situation of the grain depot, and the expansion of the expansion bag 8 will cause the position of the inner window 10 to change automatically, and cooperate with the shutter frame 5 to realize the bipolar telescopic adjustment of the thickness of the insulation layer;

[0082] The ventilation assembly rotates the drive shaft 22 on the window frame 1, and uses the linkage cone gear, square shaft 24, tail cone gear and second chain belt to make the valve column 21 rotate synchronously, so as to change the relative position between the ventilation area and the ventilation strip hole 20, and accurately adjust the ventilation area to meet the different environmental requirements in the grain depot;

[0083] In terms of sealing and reinforcement, the pneumatic booster system inflates the sealing ring bag 12 to make it fit the contact part of the window frame 1 with the outside world and increase the connection area with the wall, thereby improving the thermal insulation performance;

[0084] The rotation of the bidirectional screw rod 26 in the telescopic reinforcement component drives the driving block 27 and the support arm 28 to extend the reinforcement plate 25. At the same time, the reinforcement bag 29 is inflated to reduce the gap rate with the wall, improve the connection tightness, and enhance the structural strength of the window frame 1. The air pump 30 of the pneumatic booster system supplies air to the reinforcement bag 29, the sealing ring bag 12 and the expansion bag 8 through the air guide hose. On the other hand, the vacuum suction cup 32 is adsorbed on the wall of the grain warehouse through the suction port to further fix the outer window 2. The one-way air inlet valve 33 ensures the one-way flow of gas to ensure the stable operation of the entire thermal insulation window system.
