Description

Technical Field

[0001] This application relates to the field of closing devices, and more particularly to an intelligent opening and closing device for a grain depot insulation window. Background Technology

[0002] Grain storage typically requires specialized grain silos. These silos need to maintain a constant temperature and prevent explosions due to increased internal dust, necessitating numerous windows. These windows are usually located at the top of the silo walls, with the grain piled lower than the window height to ensure unobstructed airflow. With technological advancements, grain silo systems have become increasingly sophisticated. Insulated windows, temperature and humidity monitoring systems, and other supporting facilities can be controlled by a sophisticated control system, allowing for precise control of the opening and closing of windows at any location.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: When the existing insulated windows are opened, the window panels flip outwards. The flipping methods include upward, left-right, and downward flipping. Regardless of the flipping method, the window panels will still obstruct the airflow on one side into the grain silo. If the window panels are exactly opposite to the airflow direction, it will greatly reduce the ventilation in the grain silo and cannot guarantee that the grain silo has enough ventilation time. Summary of the Invention

[0004] This application provides an intelligent opening and closing device for grain depot insulation windows, which solves the technical problem in the prior art where the window panel flips outwards in various ways, such as upward, left-right, and downward flips, and the window panel still obstructs the airflow to the grain depot on one side, thus failing to guarantee sufficient ventilation time. The device achieves that the window panel not only does not obstruct the airflow to the grain depot, but also disperses the airflow within the grain depot, increasing the ventilation area inside the grain depot.

[0005] This application provides an intelligent opening and closing device for a grain depot insulated window. The device is installed on the window frame and includes: a cross frame installed in the window frame; equal-length fixed cross blocks fixed to the middle of the side wall of the cross frame facing the inside of the grain depot; several outer swing rods, each hinged to a side plate of the equal-length fixed cross block, the outer swing rods being symmetrical about the central axis of the equal-length fixed cross block; and right-angle window panels, each with a right-angle window panel on both sides of each outer swing rod, the hypotenuse of the right-angle window panel hinged to the outer swing rod, the right-angle sides of adjacent right-angle window panels being hinged to each other, the folding direction of the right-angle window panels facing the inside of the grain depot, and the right-angle window panels being in an unfolded state. The lower edge is fitted to the inner wall of the window frame; a lead screw, perpendicular to the window frame and located inside the window frame, one end of the lead screw is rotatably mounted on the equal-length fixed cross block, and the lead screw is threadedly connected to the equal-length movable cross block; a mounting plate is located at the end of the lead screw away from the equal-length fixed cross block and is rotatably connected to the lead screw, and a connecting rod is fixed between the mounting plate and the granary wall; a motor is fixed on the mounting plate and is used to drive the lead screw to rotate; several inner swing rods are provided, and the several inner swing rods are symmetrical about the central axis of the equal-length movable cross block, one end of the inner swing rod is hinged to the side plate of the equal-length movable cross block, and the other end is hinged to the hinge axis where the right-angle sides of two adjacent right-angle window panels are hinged to each other.

[0006] Furthermore, a hinged cylinder is fixed to the side of the right-angle window panel. The right-angled sides and hypotenuses of two adjacent right-angle window panels are hinged to each other through the hinged cylinders fixed to the side of the right-angle window panels. Gaps are left between the right-angled sides and hypotenuses of two adjacent right-angle window panels. The hinged cylinders on the hypotenuses of two adjacent right-angle window panels are sleeved on the outer swing rod, and the outer swing rod is located in the gap between the hypotenuses of two adjacent right-angle window panels. A rubber sealing strip is connected between the right-angled sides of two adjacent right-angle window panels. A sealing component for sealing the gap between the hypotenuses of two adjacent right-angle window panels is provided between the equal-length fixed cross block and the equal-length movable cross block.

[0007] Furthermore, the end of the outer swing rod away from the equal-length fixed cross block is located at the middle position of the hypotenuse of the right-angle window panel.

[0008] Furthermore, a ventilation groove is provided on the outer swing rod along the length of the outer swing rod, and the ventilation groove corresponds to the gap between the hypotenuses of two adjacent right-angle window panels.

[0009] Furthermore, the sealing assembly includes: a sealing sheet fitted onto the lead screw, the sealing sheet comprising a sealing base plate fitted onto the lead screw and sealing strips folded onto the side of the sealing base plate, the sealing base plate being used to seal the gap at the equal-length fixed cross block, and several sealing strips being provided, each corresponding to a gap between the hypotenuses of two adjacent right-angle window panels; a suspended block located between two adjacent inner swing rods; a spring fixed between the suspended block and the inner swing rod; and a slide rail fixed to the sealing strips away from the right-angle window. On one side wall of the panel; a slider, slidably mounted on the slide rail; a support strip, hinged between the slider and the suspended block; a support column, fixed between the sealing soft sheet and the equal-length fixed cross block; wherein, when several right-angle window panels are in the unfolded state, the sealing bottom sheet abuts against the equal-length fixed cross block, and the sealing strip abuts against the hypotenuse of two adjacent right-angle window panels; when several right-angle window panels are in the retracted state, the sealing bottom sheet disengages from the equal-length fixed cross block, and the sealing strip bends away from the right-angle window panel.

[0010] Furthermore, the two ends of the slider extend to the two ends of the sealing strip, respectively.

[0011] Furthermore, the end of the cross bracket is fixed to the corner of the window frame.

[0012] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0013] Because of the use of several right-angle window panels, when these panels are retracted towards the inside of the grain silo, airflow is facilitated. The air comes into contact with the inclined right-angle window panels, causing different airflows into the grain silo, thus increasing the ventilation area inside the grain silo. When the right-angle window panels are unfolded, their edges fit against the inner wall of the window frame, and the sealing components seal the gaps at the equal-length fixed cross blocks and the gaps between the inclined sides of the right-angle window panels on both sides of the outer swing rod. This ensures that the window panels not only do not obstruct the flow of air into the grain silo, but also disperse the airflow within the grain silo, further increasing the ventilation area inside the grain silo.

[0021] The technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-3 A smart opening and closing device for a grain depot insulated window is installed on the window frame 1. The opening and closing device includes a cross frame 2, equal-length fixed cross blocks 3, an outer swing rod 4, a right-angle window plate 5, a screw rod 6, a mounting plate 7, a motor 8, an inner swing rod 9, and a sealing component 10.

[0023] The window frame 1 is rectangular, but can also be square. The window frame 1 is installed on a window opening in the granary wall, and the window opening is located near the top of the granary wall.

[0024] The cross bracket 2 is fixedly connected to the window frame 1. The four ends of the cross bracket 2 are fixedly connected to the four corners of the inner edge of the window frame 1. The middle of the cross bracket 2 is a circular seat, which is located at the center of the window frame 1.

[0025] The cross section of the equal-length fixed cross block 3 is cross-shaped, and the middle is also a circular seat. The equal-length fixed cross block 3 is fixedly connected to the side wall of the cross frame 2 facing the inside of the grain warehouse, and the circular seat of the equal-length fixed cross block 3 is coaxial with the circular seat of the cross frame 2.

[0026] The outer swing rod 4 is a round rod with a ventilation groove 41. The ventilation groove 41 has a rectangular cross-section, and its length is aligned with that of the outer swing rod 4. Both ends of the ventilation groove 41 are close to the ends of the outer swing rod 4. One end of the outer swing rod 4 is hinged to the equal-length fixed cross block 3. There are four outer swing rods 4, each hinged to one of the side plates of the equal-length fixed cross block 3. The axis of the circular seat of the equal-length fixed cross block 3 is located on the swing surface of the outer swing rod 4.

[0027] The right-angle window panel 5 is an isosceles right triangle. Each outer swing rod 4 has a right-angle window panel 5 on both sides. The hypotenuse of the right-angle window panel 5 on both sides of each outer swing rod 4 is parallel to the outer swing rod 4. There is a gap between the hypotenuses of the right-angle window panels 5 on both sides of the outer swing rod 4. The end of the outer swing rod 4 away from the equal-length fixed cross block 3 is located at the middle position of the hypotenuse of the right-angle window panel 5. The ventilation groove 41 on the outer swing rod 4 corresponds to the gap between the hypotenuses of the two right-angle window panels 5.

[0028] One right-angled side of each of the two right-angled window panels 5 between the two outer swing rods 4 is parallel to the other, with a gap between the two right-angled sides. A hinged cylinder 51 is fixed to the hypotenuse of the right-angled window panel 5, and the upper hinged cylinder 51 of the hypotenuse of the right-angled window panel 5 is fitted onto the end of the outer swing rod 4 away from the equal-length fixed cross block 3. Hinged cylinders 51 are also fixed to the parallel right-angled sides of the two right-angled window panels 5. The hinged cylinders 51 on the right-angled sides of the two right-angled window panels 5 are coaxial and hinged together by a hinge shaft. The axis of the outer swing rod 4 is located on the side of the right-angled window panel 5 facing outwards from the grain silo, and the axis of the hinged cylinders 51 on the right-angled sides of the two right-angled window panels 5 between the two outer swing rods 4 is located on the side of the right-angled window panel 5 facing inwards from the grain silo.

[0029] The lead screw 6 is located on the side of the cross frame 2 facing the grain bin. One end of the lead screw 6 is rotatably mounted on the circular seat of the cross frame 2. The lead screw 6 is threaded with an equal-length movable cross block 61. The structure of the equal-length movable cross block 61 is the same as that of the equal-length fixed cross block 3.

[0030] The mounting plate 7 is located at the end of the screw 6 away from the cross frame 2, and a connecting rod 71 is fixed between the mounting plate 7 and the grain silo wall. The connecting rod 71 is used to stabilize the mounting plate 7, and the end of the screw 6 away from the cross frame 2 is rotatably mounted on the mounting plate 7.

[0031] The motor 8 is mounted on the side wall of the mounting plate 7 away from the lead screw 6, and the motor 8 is used to drive the lead screw 6 to rotate.

[0032] One end of the inner swing rod 9 is hinged to the equal-length moving cross block 61, and the other end is hinged to the hinge axis between the right-angled sides of the two right-angled window panels 5. The inner swing rod 9 is hinged between the hinge axis between the right-angled sides of each pair of right-angled window panels 5 and the equal-length moving cross block 61.

[0033] When the motor 8 starts, it will drive the equal-length moving cross block 61 on the lead screw 6 to move towards one end of the equal-length fixed cross block 3. During the movement, the equal-length moving cross block 61 will push the inner swing rod 9 to swing towards one side of the window frame 1, thereby causing several right-angle window panels 5 to unfold. When the several right-angle window panels 5 are in the final unfolded state, the several right-angle window panels 5 will be in a coplanar state, and the edge of the right-angle side of the right-angle window panel 5 that is connected to the axis of the outer swing rod 4 away from the equal-length fixed cross block 3 will be attached to the inner wall of the window frame 1.

[0034] When the motor 8 drives the equal-length moving cross block 61 on the lead screw 6 to move towards one end of the mounting plate 7, it causes several right-angle window panels 5 to retract. The retraction direction of these right-angle window panels 5 faces inward towards the grain silo, and the swing angle of the outer swing rod 4 can be set to 45 degrees for the final retracted state. After the several right-angle window panels 5 retract, air circulation is achieved, allowing external air to enter the grain silo. Because the swing angle of the swing rod is set to 45 degrees, the right-angle window panels 5 are tilted. As air flows into the grain silo, it comes into contact with the tilted right-angle window panels 5, causing the air to enter the grain silo in different directions, thus increasing the ventilation area inside the grain silo.

[0035] Reference Figure 3 A rubber sealing strip 52 is fixed between the parallel right-angled sides of the two right-angled window panels 5 between the two outer swing rods 4. The edge of the rubber sealing strip 52 is fixed to the edge of the right-angled window panel 5 facing the outer side of the grain silo. The rubber sealing strip 52 can seal the gap between the right-angled sides of the two right-angled window panels 5. The sealing assembly 10 is located on the side of the right-angled window panel 5 facing the inside of the grain silo. The sealing assembly 10 is located between the equal-length fixed cross block 3 and the equal-length movable cross block 61. The sealing assembly 10 is used to seal the gap between the hypotenuses of two adjacent right-angled window panels 5.

[0036] Reference Figures 4-6 The sealing assembly 10 includes a sealing sheet 101, a suspension block 102, a spring 103, a slide rail 104, a slider 105, a support bar 106, and a support column 107.

[0037] The sealing strip 101 can be made of rubber. The sealing strip 101 includes an integrally formed sealing base 1011 and sealing strips 1012. The sealing base 1011 is square and is fitted onto the lead screw 6, positioned between the equal-length fixed cross block 3 and the equal-length movable cross block 61. The sealing base 1011 is perpendicular to the lead screw 6. The sealing strips 1012 are strip-shaped, with four strips located on each side of the sealing base 1011. The sealing strips 1012 and the sealing base 1011 can be bent, and the sealing strips 1012 correspond to the outer swing rod 4. The sealing strips 1012 are used to seal the gap between the inclined sides of the right-angle window panels 5 on both sides of the outer swing rod 4, and the sealing base 1011 is used to seal the gap at the equal-length fixed cross block 3.

[0038] A suspended block 102 is located between two adjacent inner swing rods 9, and a suspended block 102 is provided between every two inner swing rods 9. The suspended block 102 is located at the middle position of the inner swing rod 9. A spring 103 is provided on both sides of each suspended block 102. One end of the spring 103 is fixed to the suspended block 102, and the other end is fixed to the inner swing rod 9. A slide rail 104 is fixed to the side wall of the sealing stack 1012 facing the inside of the grain bin. The length direction of the slide rail 104 is consistent with the length direction of the sealing stack 1012, and the two ends of the slide rail 104 are close to the two ends of the sealing stack 1012. A slide rail 104 is fixed on each sealing stack 1012. A slider 105 is slidably disposed on the slide rail 104. A support bar 106 is provided between each slider 105 and the suspended block 102. One end of the support bar 106 is hinged to the slider 105, and the other end is hinged to the suspended block 102. The support column 107 is fixed between the equal-length movable cross block 61 and the sealing soft sheet 101.

[0039] When the equal-length moving cross block 61 on the lead screw 6 moves toward the equal-length fixed cross block 3, the support column 107 also moves toward the equal-length fixed cross block 3. When several right-angle window panels 5 are in the final unfolded state, the sealing bottom plate 1011 will abut against the equal-length fixed cross block 3. During the unfolding process of the right-angle window panels 5, the suspended block 102 between the inner swing rods 9 will move toward the equal-length fixed cross block 3, causing the support bar 106 to swing. This will push the sealing stack 1012 to abut against the gap between the inclined sides of the right-angle window panels 5 on both sides of the outer swing rod 4. Thus, the sealing soft plate 101 seals the gap at the equal-length fixed cross block 3 and the gap between the inclined sides of the right-angle window panels 5 on both sides of the outer swing rod 4.

[0040] The functional principle of this application can be explained through the following methods:

[0041] When ventilation of the grain silo is required, the motor 8 is started, causing the equal-length moving cross block 61 on the lead screw 6 to move towards the mounting plate 7. Several right-angle window panels 5 retract towards the inside of the grain silo, allowing air to circulate between the inside and outside. Since the air comes into contact with the inclined right-angle window panels 5, it enters the grain silo in different directions, increasing the ventilation area inside the grain silo. Furthermore, since the outer swing rod 4 has ventilation slots 41, external air can also enter the grain silo through the ventilation slots 41 on the outer swing rod 4, or through the gaps between the inclined sides of the right-angle window panels 5 on both sides of the outer swing rod 4, thus accelerating air circulation.

[0042] When it is necessary to seal the window frame 1, the motor 8 drives the equal-length moving cross block 61 on the lead screw 6 to move towards the equal-length fixed cross block 3, which will cause several right-angle window panels 5 to unfold. The edges of the right-angle sides of the right-angle window panels 5 will fit against the inner wall of the window frame 1. When the several right-angle window panels 5 are in the final unfolded state, the sealing bottom plate 1011 will abut against the equal-length fixed cross block 3, and the sealing strip 1012 will abut against the gap between the inclined sides of the right-angle window panels 5 on both sides of the outer swing rod 4, thus completing the sealing.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
