Description

Technical Field

[0001] This utility model relates to the field of aquaculture ventilation technology, specifically to a double-opening louver structure. Background Technology

[0002] In existing technologies, the sealing structures of livestock fans used for ventilation and cooling are mainly divided into two types: butterfly valve type and louver type. For the louver type opening structure, this structure is usually installed on the inlet side of the fan and employs a self-balancing design, allowing the louvers to open under wind force and close under gravity. Currently, most louvers on the market use a two-sided linkage design, meaning all louvers open in the same direction, forming a so-called louver linkage structure. However, when the fan is operating at a variable speed and the airflow is low, the louvers cannot fully open, causing the airflow direction to be unfavorable for smooth airflow into the fan interior, thus increasing wind resistance.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a split-opening louver structure to solve the technical problem in the related technology that when the fan is running at a variable speed and the air volume is small, the louvers cannot be fully opened, which makes the airflow direction unfavorable to the smooth entry of airflow into the fan, thereby increasing the wind resistance.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: A double-opening louver structure is provided, comprising: a louver opening and closing component, movably mounted on the window frame, the louver opening and closing component being used to change the airflow direction, the louver opening and closing component including a first louver assembly and a second louver assembly, both the first louver assembly and the second louver assembly having an open / closed state and a closed state, the first louver assembly and the second louver assembly being spaced apart along the height direction of the window frame, and the opening and closing directions of the first louver assembly and the second louver assembly being opposite; a linkage component, the linkage component being mounted on one side of the window frame, the linkage component being connected to the first louver assembly and the second louver assembly respectively, the linkage component being used to make the first louver assembly and the second louver assembly move synchronously, thereby controlling the first louver assembly and the second louver assembly to be in the open / closed state or the closed state.

[0006] Further, the first blade assembly includes: at least two first blades, each first blade being spaced apart on the window frame along the height direction of the window frame, and both ends of each first blade being movably mounted on the window frame; the second blade assembly includes: at least two second blades, each second blade being disposed opposite to each first blade, each second blade being spaced apart on the window frame along the height direction of the window frame, both ends of each second blade being movably mounted on the window frame, and the movement direction of each second blade being opposite to the movement direction of each first blade; wherein, when two adjacent first blades, two adjacent second blades, and adjacent first and second blades are all in abutting state, each first blade and each second blade are in the closed state; otherwise, they are in the open state.

[0007] Further, the linkage component includes: a first connecting component, which is connected to each of the first blades; a second connecting component, which is connected to each of the second blades, and the second connecting component is spaced apart from the first connecting component; and a linkage component, which is connected to both the first and second connecting components, and is movably arranged relative to the first and second connecting components, and is used to drive the first and second connecting components to move synchronously; wherein, when the first blade is in the open state, the first connecting component drives each of the second blades connected to the second connecting component to be in the open state synchronously through the linkage component; when the first blade is in the closed state, the first connecting component drives each of the second blades connected to the second connecting component to be in the closed state synchronously through the linkage component.

[0008] Furthermore, the first connecting assembly includes: at least two first connecting plates, each first connecting plate being configured to correspond one-to-one with each first blade, and each first connecting plate being connected to a corresponding first blade to drive the corresponding first blade to rotate; the second connecting assembly includes: at least two second connecting plates, each second connecting plate being configured to correspond one-to-one with each second blade, and each second connecting plate being connected to a corresponding second blade to drive the corresponding second blade to rotate.

[0009] Furthermore, the linkage assembly includes: a first linkage plate, wherein the side of each first connecting plate away from each first blade is movably disposed on one side of the first linkage plate via a rotating shaft, the first linkage plate being used to connect the first connecting plates so that each first blade is simultaneously in an open or closed state by driving the first connecting plates to move synchronously; a second linkage plate, wherein the side of each second connecting plate away from each second blade is movably disposed on one side of the second linkage plate via a rotating shaft, the second linkage plate being used to connect the second connecting plates so that each second blade is simultaneously in an open or closed state by driving the second connecting plates to move synchronously; both the first linkage plate and the second linkage plate extend along the height direction of the window frame and are spaced apart along the height direction of the window frame; and a transmission component, which is connected to the first linkage plate and the second linkage plate respectively, and the transmission component is used to drive the first linkage plate and the second linkage plate to move synchronously.

[0010] Further, the transmission component includes: a first crank extending along a first preset direction, one side of the first crank being movably disposed with respect to the side of any of the first connecting plates away from each of the first blades, and the first crank being disposed at intervals with the first linkage plate; a second crank extending along a second preset direction, one side of the second crank being movably disposed with respect to the side of any of the second connecting plates away from each of the second blades, and the second crank being disposed at intervals with the second linkage plate; and a connecting rod movably disposed with respect to the side of the first crank away from each of the first connecting plates and the side of the second crank away from each of the second connecting plates.

[0011] Furthermore, the double-opening louver structure also includes: a stop plate, which is installed on the window frame and is spaced apart from the connecting rod. The stop plate is used to abut against the connecting rod. When each of the first connecting plates and each of the second connecting plates is in the closed state, the connecting rod abuts against the stop plate.

The connecting plate is used to abut against at least a portion of the first blade assembly and the second blade assembly on the side closest to each other.

[0013] Beneficial effects:

[0014] 1. By designing the first and second blade assemblies to be spaced apart along the height of the window frame and opening and closing in opposite directions, the two sets of blades form a complementary airflow guiding structure. The first and second blade assemblies generate staggered airflow channels, doubling the level of airflow direction adjustment. The reverse movement trajectories of the two sets of blades can offset part of the wind pressure load. The synchronous control mechanism of the linkage components ensures the consistency of the movement of the two sets of blades, avoiding airflow turbulence caused by the phase difference of movement. This solves the technical problem in related technologies where, when the fan is running at a variable speed and the air volume is small, the louvers cannot be fully opened, resulting in the airflow direction being unfavorable to the smooth entry of airflow into the fan, thus increasing wind resistance.

[0015] 2. The first crank and the second crank are respectively connected to two vertical transmission planes, and the connecting rod is set with two pivot nodes to form a compound motion trajectory. This design enables the first linkage plate and the second linkage plate to generate phase difference compensation during the movement, ensuring that the opening and closing actions of the two sets of blades form a complementary airflow channel.

[0016] 3. The stop plate and the connecting rod form a limiting structure. When the first blade and the second blade are closed, the connecting rod contacts the stop plate at the same time. The limiting effect of the stop plate improves the wind pressure resistance in the closed state and prevents the first blade and the second blade from flipping in opposite directions.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] According to an embodiment of this utility model, a double-opening louver structure is provided. Please refer to [link / reference]. Figures 1 to 4 The system includes: a louver opening and closing component 1, movably mounted on the window frame 2, the louver opening and closing component 1 being used to change the direction of airflow, the louver opening and closing component including a first blade assembly and a second blade assembly, both the first blade assembly and the second blade assembly having an open / closed state and a closed state, the first blade assembly and the second blade assembly being spaced apart along the height direction of the window frame 2, and the opening and closing directions of the first blade assembly and the second blade assembly being opposite; and a linkage component 3, the linkage component 3 being mounted on one side of the window frame 2, the linkage component 3 being connected to the first blade assembly and the second blade assembly respectively, the linkage component 3 being used to make the first blade assembly and the second blade assembly move synchronously, so as to control the first blade assembly and the second blade assembly to be in the open / closed state or the closed state.

[0025] By adopting the above technical solution, when the fan is turned on, the first and second blade assemblies are spaced apart along the height of the window frame 2 and open and close in opposite directions. The two sets of blades form a complementary airflow guiding structure. The first and second blade assemblies generate staggered airflow channels, which doubles the level of airflow direction adjustment. The reverse movement trajectories of the two sets of blades can offset part of the wind pressure load. The synchronous control mechanism of the linkage component 3 ensures the consistency of the movement of the two sets of blades and avoids airflow turbulence caused by the difference in movement phase. This solves the technical problem in related technologies where, when the fan is running at a variable speed and the air volume is small, the louvers cannot be fully opened, resulting in the airflow direction being unfavorable to the smooth entry of airflow into the fan, thus increasing wind resistance.

[0026] Please refer to Figure 1 and Figure 2The first blade assembly includes at least two first blades 4, each first blade 4 being spaced apart on the window frame 2 along the height direction of the window frame 2, and both ends of each first blade 4 being movably mounted on the window frame 2; the second blade assembly includes at least two second blades 5, each second blade 5 being disposed opposite to each first blade 4, each second blade 5 being spaced apart on the window frame 2 along the height direction of the window frame 2, both ends of each second blade 5 being movably mounted on the window frame 2, and the movement direction of each second blade 5 being opposite to the movement direction of each first blade 4; wherein, when two adjacent first blades 4, two adjacent second blades 5, and adjacent first blades 4 and second blades 5 are all in abutting state, each first blade 4 and each second blade 5 are in the closed state; otherwise, they are in the open state.

[0027] By adopting the above technical solution, the first blade 4 and the second blade 5 each form a symmetrical array structure through at least two independent blade units, and the movable connection design at both ends of each blade gives it bidirectional motion freedom. When adjacent first blades 4 and second blades 5 are fully abutted, two sets of staggered closed planes are formed, achieving a seal.

[0028] Please refer to Figure 2 The linkage component 3 includes: a first connecting component, which is connected to each of the first blades 4; a second connecting component, which is connected to each of the second blades 5, and the second connecting component is spaced apart from the first connecting component; and a linkage component, which is connected to both the first connecting component and the second connecting component, and is movably arranged relative to the first and second connecting components. The linkage component is used to drive the first and second connecting components to move synchronously. Specifically, when the first blades 4 are in the open state, the first connecting component drives each of the second blades 5 connected to the second connecting component to be in the open state synchronously through the linkage component; when the first blades 4 are in the closed state, the first connecting component drives each of the second blades 5 connected to the second connecting component to be in the closed state synchronously through the linkage component.

[0029] By adopting the above technical solution, the linkage component 3 establishes independent transmission paths with the first blade 4 and the second blade 5 through the first connecting component and the second connecting component respectively, and the linkage component is provided with two reverse transmission branches; when the linkage component moves, the first connecting component and the second connecting component transmit motion synchronously through at least three hinge nodes to ensure that the phase difference between the two sets of blades is controlled within a preset range.

[0030] Please refer to Figure 2 and Figure 3The first connecting component includes at least two first connecting plates 6, each first connecting plate 6 being configured to correspond one-to-one with each first blade 4, and each first connecting plate 6 being connected to the corresponding first blade 4 so as to drive the corresponding first blade 4 to rotate through each first connecting plate 6; the second connecting component includes at least two second connecting plates 7, each second connecting plate 7 being configured to correspond one-to-one with each second blade 5, and each second connecting plate 7 being connected to the corresponding second blade 5 so as to drive the corresponding second blade 5 to rotate through each second connecting plate 7.

[0031] By adopting the above technical solution, each first connecting plate 6 and each first blade 4 are rigidly connected at a single point, and each second connecting plate 7 and each second blade 5 are connected in the same way, forming a 1:1 transmission ratio. Each first connecting plate 6 and each second connecting plate 7 are hinged to the linkage assembly through the rotating shaft 10, so that the rotation angle deviation of the multiple first blades 4 and second blades 5 approaches zero.

[0032] Please refer to Figure 3 The linkage assembly includes: a first linkage plate 8, wherein each first connecting plate 6 is movably disposed on one side of the first linkage plate 8 via a rotating shaft 10 on the side away from each first blade 4, and the first linkage plate 8 is used to connect each first connecting plate 6 so that each first blade 4 is simultaneously in an open or closed state by driving each first connecting plate 6 to move synchronously; a second linkage plate 9, wherein each second connecting plate 7 is movably disposed on one side of the second linkage plate 9 via a rotating shaft 10 on the side away from each second blade 5, and the second linkage plate 9 is used to connect each second connecting plate 7 so that each second blade 5 is simultaneously in an open or closed state by driving each second connecting plate 7 to move synchronously; both the first linkage plate 8 and the second linkage plate 9 extend along the height direction of the window frame 2 and are spaced apart along the height direction of the window frame 2; and a transmission member 11, which is connected to the first linkage plate 8 and the second linkage plate 9 respectively, and the transmission member 11 drives the first linkage plate 8 and the second linkage plate 9 to move synchronously.

[0033] By adopting the above technical solution, the first linkage plate 8 and the second linkage plate 9 extend along the height of the window frame 2 to form a parallel guide rail structure, and the transmission component 11 constructs a transmission chain through the first crank 12, the second crank 13 and the connecting rod 14. This structure decomposes the single driving force into two sets of opposite motion components, ensuring that the opening and closing stroke ratio of the first blade 4 and the second blade 5 remains corresponding.

[0034] Please refer to Figure 3 and Figure 4The transmission component 11 includes: a first crank 12, which extends along a first preset direction, and one side of the first crank 12 is movably disposed with respect to the side of any one of the first connecting plates 6 away from the respective first blades 4, and the first crank 12 is disposed at intervals with the first linkage plate 8; a second crank 13, which extends along a second preset direction, and one side of the second crank 13 is movably disposed with respect to the side of any one of the second connecting plates 7 away from the respective second blades 5, and the second crank 13 is disposed at intervals with the second linkage plate 9; and a connecting rod 14, which is movably disposed with respect to the side of the first crank 12 away from the respective first connecting plates 6 and the side of the second crank 13 away from the respective second connecting plates 7.

[0035] By adopting the above technical solution, the first crank 12 and the second crank 13 are respectively connected to two vertical transmission planes, and the connecting rod 14 is set with two pivot nodes to form a compound motion trajectory. This design enables the first linkage plate 8 and the second linkage plate 9 to generate phase difference compensation during the movement, ensuring that the opening and closing actions of the two sets of blades form a complementary airflow channel.

[0036] Please refer to Figure 4 The double-opening louver structure also includes: a stop plate 15, which is installed on the window frame 2. The stop plate 15 is spaced apart from the connecting rod 14 and is used to abut against the connecting rod 14. When each of the first connecting plates 6 and each of the second connecting plates 7 are in the closed state, the connecting rod 14 abuts against the stop plate 15.

[0037] By adopting the above technical solution, the stop plate 15 and the connecting rod 14 form a limiting structure. When the first blade 4 and the second blade 5 are closed, the connecting rod 14 simultaneously contacts the stop plate 15. Through the limiting of the stop plate 15, the wind pressure resistance of the closed state is improved and the first blade 4 and the second blade 5 are prevented from flipping in the opposite direction.

[0038] Please refer to Figure 1 The double-opening louver structure also includes: a connecting plate 16, which is disposed on the window frame 2 and extends along the width direction of the window frame 2. Figure 2 The direction of the middle arrow A is the width direction of the window frame 2, and the connecting plate 16 is used to abut against at least a portion of the first blade assembly and the second blade assembly on the side closest to each other.

[0039] By adopting the above technical solution, the connecting plate 16 extends along the width direction of the window frame 2 to form a support surface, and forms a cross contact area with the first blade assembly and the second blade assembly. In the closed state, the connecting plate 16 simultaneously abuts against the opposite sides of two adjacent blades in the first blade assembly and the second blade assembly, thereby improving the overall sealing effect.

[0040] Working principle:

[0041] When the fan is turned on, air begins to enter the fan. At this time, the suction force generated by the fan drives the first blades 4 and the second blades 5 to move. The first blades 4 and the second blades 5 change from the closed state to the open state. In order to ensure the consistency of the opening of the first blades 4 and the second blades 5, when the first blades 4 or the second blades 5 move, they will rotate through the corresponding first connecting plates 6 and the second connecting plates 7, thereby driving the first linkage plate 8 and the second linkage plate 9 to move relative to each other along the height direction of the window frame 2. Then, through the first crank 12, the second crank 13 and the connecting rod 14, a compound motion trajectory is formed to ensure that the opening and closing actions of the first blades 4 and the second blades 5 form a complementary airflow channel.
