[0027] The present application provides a flood-proof rolling shutter door 100, see Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of an embodiment of a flood-proof rolling shutter door provided by the present application, Figure 2 yes Figure 1 The schematic diagram of the local structure of the flood-proof rolling shutter door when it is in the rolled-up state.

[0028] The flood-proof rolling shutter door 100 is installed at the entrance and exit of a building. It can be used as an ordinary rolling shutter door in daily use. In a flooding scenario, the flood-proof rolling shutter door 100 can also form a water retaining wall at the entrance and exit of the building to prevent water from entering the building.

[0029] The flood-proof rolling shutter door 100 includes a rolling shutter assembly 10, a rolling shutter mechanism 20 and a clamping mechanism 30. The rolling shutter mechanism 20 is used to drive the rolling shutter assembly 10 to retract or extend. The clamping mechanism 30 can provide a clamping force to a portion of the rolling shutter assembly 10 located in a preset area, so that the formed retaining wall is more stable and less prone to water leakage.

[0030] The rolling shutter assembly 10 may include a plurality of rolling shutter sheets 11 connected in series, that is, it is a commonly used rolling shutter assembly; or, the rolling shutter assembly 10 may include a plurality of anti-flooding baffles 12 connected in series, the anti-flooding baffles 12 are different from the rolling shutter sheets 11, and the plurality of anti-flooding baffles 12 can be stacked to form a water retaining wall.

[0031] In this embodiment, the rolling shutter assembly 10 includes a plurality of rolling shutter pieces 11 and a plurality of anti-flooding baffles 12 connected in sequence, and the rolling shutter pieces 11, the anti-flooding baffles 12, and the rolling shutter pieces 11 and the anti-flooding baffles 12 are all hinged; the rolling shutter mechanism 20 is connected to the rolling shutter piece 11 located at the head end of the rolling shutter assembly 10, and is used to drive the plurality of rolling shutter pieces 11 and the plurality of anti-flooding baffles 12 to retract or extend; the clamping mechanism 30 includes a first clamping assembly 31 and a second clamping assembly 32, the first clamping assembly 31 is used to clamp the plurality of anti-flooding baffles 12 from a horizontal direction, and the second clamping assembly 32 is used to clamp the plurality of anti-flooding baffles 12 on a supporting surface from a vertical direction.

[0032] The rolling shutter assembly 10 is composed of two parts, one part of which is composed of rolling shutter pieces 11, and the other part of which is composed of anti-flooding baffles 12, and the part composed of rolling shutter pieces 11 is connected to the part composed of anti-flooding baffles 12, and the plurality of anti-flooding baffles 12 can form a water retaining wall at the entrance and exit of a building. Among them, each rolling shutter piece 11, each anti-flooding baffle 12, and the rolling shutter piece 11 and the anti-flooding baffle 12 are all hinged, so that the rolling shutter piece 11 and the anti-flooding baffle 12 can be rolled up on the sky rod of the rolling shutter mechanism 20.

[0033] The rolling mechanism 20 includes a motor and a sky bar, and the motor drives the sky bar to rotate forward or reversely, so that the rolling assembly 10 is rolled up on the sky bar, or the rolling assembly 10 is extended downward from the sky bar. Wherein, the motor housing drives the sky bar to rotate through a belt, a chain or a gear set.

[0034] The flood-proof rolling shutter door 100 may further include a control box, which is in communication with the rolling shutter mechanism 20 and is used to receive signals to control the operation of the rolling shutter mechanism 20, thereby controlling the rolling shutter assembly 10 to switch between an extended state and a retracted state.

[0035] In this embodiment, the rolling shutter piece 11 and the anti-flooding baffle 12 are detachably connected, so that the anti-flooding baffle 12 can be easily and conveniently disassembled at any time. For example, the plurality of anti-flooding baffles 12 can be connected to the rolling shutter piece 11 in the rainy season, and the plurality of anti-flooding baffles 12 can be disassembled in the non-rainy season for maintenance and storage, so as to extend the service life of the plurality of anti-flooding baffles 12.

[0036] Furthermore, the anti-flooding baffles 12 are also detachably connected, so that the number of the anti-flooding baffles 12 can be conveniently adjusted, so that the height of the water retaining wall provided by them can be more suitable for the local water conditions.

[0037] like Figure 2 and Figure 3 As shown, Figure 3 yes Figure 2Schematic diagram of the structure of the flood-proof baffle in the flood-proof rolling shutter door. A connecting portion 120 is provided at the first end of the flood-proof baffle 12, and the connecting portion 120 is detachably connected to one end of the rolling shutter piece 11 through a pin shaft between the flood-proof baffle 12 and the rolling shutter piece 11; a clamping groove 122 is provided at the second end of the flood-proof baffle 12, and the connecting portion 120 is clamped on the clamping groove 122 between two adjacent flood-proof baffles 12, and the connecting portion 120 and the clamping groove 122 are hinged.

[0038] The end of the rolling shutter piece 11 is provided with a first rotating hole, the connecting portion 120 is provided with a second rotating hole, and the pin shaft connects the first rotating hole and the second rotating hole, so that the rolling shutter piece 11 and the anti-flooding baffle 12 can be detachably connected and the rolling shutter piece 11 is hinged with the anti-flooding baffle 12. This implementation method can realize manual installation without the aid of tools, can be quickly disassembled and assembled, and has high disassembly efficiency and is convenient.

[0039] The slot 122 is in a constricted shape, and the width of the slot is smaller than the spacing between the middle slot walls of the slot 122; the connecting portion 120 includes a hollow circular shaft 121 and a connecting piece 123, and the connecting piece 123 is connected between the hollow circular shaft 121 and the main body of the anti-flooding baffle 12, wherein the hollow circular shaft 121 can enter the slot 122 from the side of the slot 122, and is limited by the slot of the slot 122 and cannot fall off from the slot, and the connecting piece 123 passes through the slot of the slot 122, and the hollow circular shaft 121 can rotate in the slot 122.

[0040] It can be known that the connecting portion 120 can be simply installed in the card slot 122 along the lateral direction of the card slot 122 , and convenient disassembly and assembly can be achieved without the aid of any installation tools, which has extremely high disassembly and assembly efficiency.

[0041] Furthermore, the depth of the slot 122 is greater than the diameter of the hollow circular shaft 121 , so that the hollow circular shaft 121 can also move in the depth direction of the slot 122 , thereby facilitating the relative rotation between the anti-flooding baffles 12 .

[0042] Optionally, the anti-flooding baffles 12 and the rolling shutter sheet 11 may be connected by hinges, and the anti-flooding baffles 12 may be detachably connected by pins.

[0043] In the flood prevention mode, the rolling shutter mechanism 20 of the flood prevention rolling shutter door 100 will be under the rolling shutter assembly 10 in the rolled-up state, so that the lowered rolling shutter assembly 10 is in the extended state, and the retaining wall composed of the multiple flood prevention baffles 12 is placed on the bottom surface of the building entrance and exit, and the supporting surface can be the ground or the surface of a support located on the ground, and then the first clamping assembly 31 presses the multiple flood prevention baffles 12 from the horizontal direction, wherein the rolling shutter assembly 10 can move under the guidance of the track or the flood prevention baffle 12 is provided with a retaining wall on the side away from the first clamping assembly 31, and the first clamping assembly 31 presses the multiple flood prevention baffles 12 against the track or the retaining wall to avoid the baffles 12 from being blocked by water impact. The flood control failure caused by the movement of the water wall can also be solved by reducing the gaps through the pressing force applied by the first pressing component 31 to reduce the risk of water leakage. The second pressing component 32 applies a pressing force to the multiple anti-flooding baffles 12 in the vertical direction, which can reduce the gaps between the anti-flooding baffles 12 and the gaps between the anti-flooding baffles 12 and the supporting surface. Furthermore, the pressing force applied by the first pressing component 31 and the second pressing component 32 can effectively improve the strength of the formed retaining wall, avoid deformation and failure of the retaining wall due to water flow impact, and greatly eliminate gaps in various places to reduce the risk of water leakage, thereby effectively improving the water retaining effect and preventing water from entering the entrance and exit of the building.

[0044] The flood-proof rolling shutter door 100 may further include a control box, which is in communication with the first clamping assembly 31 and the second clamping assembly 32 to control the actions of the first clamping assembly 31 and the second clamping assembly 32; further, the control box may also communicate with the control box to cooperatively drive the rolling shutter mechanism 20 and the clamping mechanism 30.

[0045] See also Figures 2 to 4 ,in Figure 4 yes Figure 1 The schematic diagram of the local structure of the flood-proof rolling shutter door when it is in the extended state.

[0046] In this embodiment, a first sealing strip 131 is further provided at the first end of the anti-flooding baffle 12, and the connecting portion 120 can move relative to the slot 122, so that the first sealing strip 131 can abut against the second end of the adjacent anti-flooding baffle 12, and the first sealing strip 131 is used to seal the gap between two adjacent anti-flooding baffles 12.

[0047] A first sealing strip 131 is installed at the first end of each anti-flooding baffle 12. The first sealing strip 131 can be snapped onto the first end of the anti-flooding baffle 12. The length of the first sealing strip 131 is equal to the length of the anti-flooding baffle 12. Therefore, when two adjacent anti-flooding baffles 12 abut against each other, the first sealing strip 131 is squeezed by the two anti-flooding baffles 12 to seal the gap between the anti-flooding baffles 12, so as to reduce the gap between the anti-flooding baffles 12 that leaks water.

[0048] Optionally, a first sealing strip 131 may be provided at the first end of the anti-flooding baffle 12 .

[0049] In this embodiment, two first sealing strips 131 are disposed at the first end of the anti-flooding baffle 12 . The two first sealing strips 131 are located on both sides of the connecting portion 120 , which can enhance the sealing effect and ensure smooth docking between two adjacent anti-flooding baffles 12 .

[0050] Furthermore, the slot 122 of the anti-flooding baffle 12 at the rear end of the rolling shutter assembly 10 is also connected to a second sealing strip 132 , and the second sealing strip 132 is used to seal the gap between the anti-flooding baffle 12 and the supporting surface.

[0051] The second sealing strip 132 is clamped in the clamping groove 122 , and the length of the second sealing strip 132 is equal to the length of the anti-flooding baffle 12 , and the width of the second sealing strip 132 is equal to the width of the anti-flooding baffle 12 , so that a good sealing effect can be achieved between the anti-flooding baffle 12 and the supporting surface, and the anti-flooding baffle 12 can also be well supported.

[0052] In addition, under the pressing force applied by the second pressing assembly 32 , the first sealing strip 131 and the second sealing strip 132 are both pressed to achieve good sealing, which can further improve the sealing effect and reduce the risk of water leakage.

[0053] Combined with reference Figure 1 , Figure 4 and Figure 6 In this embodiment, the flood-proof rolling shutter door 100 also includes two vertical slide rails 40 arranged at intervals, and the two sides of the rolling shutter assembly 10 are slidably arranged in the vertical slide rails 40, wherein the vertical slide rails 40 are also provided with a third sealing strip 133; under the force applied by the first clamping assembly 31, the plurality of flood-proof baffles 12 and the vertical slide rails 40 are sealed by the third sealing strip 131.

[0054] The third sealing strip 133 is clamped on the vertical slide rail 40 , and its height is greater than or equal to the height of the water retaining wall formed by the plurality of anti-flooding baffles 12 . The clamping force applied by the first clamping assembly 31 enables the third sealing strip 133 to achieve good sealing between the water retaining wall and the vertical slide rail 40 .

[0055] By providing a third sealing strip 133 on both vertical slide rails 40, providing a first sealing strip 131 at the first end of the anti-flood baffle 12, and providing a second sealing strip 132 at the anti-flood baffle 12 at the rear end of the rolling shutter assembly 10, and combining the sealing strips at these three locations with the clamping force applied by the first clamping assembly 31 and the second clamping assembly 32, the formed retaining wall and the entrance and exit of the building can form a reliable sealing structure, greatly reducing the risk of water entering the building.

[0056] like Figure 4 As shown, the first clamping assembly 31 includes a first driving member 311, a clamping plate 312 and a plurality of swinging members 313. The plurality of swinging members 313 are evenly distributed on one side of the clamping plate 312 and are swingably connected to the clamping plate 312. The first driving member 311 is connected to the clamping plate 312 and is used to drive the clamping plate 312 to swing between a first position and a second position. The clamping plate 312 clamps the plurality of anti-flooding baffles 12 horizontally when in the first position, and is spaced apart from the plurality of anti-flooding baffles 12 when in the second position.

[0057] The clamping plate 312 is a flat plate structure, and the height of the clamping plate 312 can be roughly equivalent to the height of the water retaining wall. It swings under the restriction of multiple swinging members 313, wherein the swinging member 313 is a swing arm, one end of the swinging member 313 is rotatably connected to the clamping plate 312, and the other end of the swinging member 313 is rotatably connected to a fixed seat installed on one side of the vertical slide rail 40. The multiple swinging members 313 are evenly connected to the clamping plate 312, so that the clamping plate 312 can swing smoothly under the restriction of the multiple swinging members 313, thereby allowing the clamping plate 312 to apply a uniform clamping force to various parts of the water retaining wall to improve the sealing between the water retaining wall and the vertical slide rail 40.

[0058] The first driving member 311 includes an electric push rod and a rocker arm. The middle part of the rocker arm is rotatably connected to the fixed seat. One end of the rocker arm is rotatably connected to the clamping plate 312, and the other end of the rocker arm is rotatably connected to the driving end of the electric push rod. The electric push rod drives the rocker arm to swing, thereby driving the clamping plate 312 to move closer to or away from the water retaining wall, so as to apply or remove the clamping force to the water retaining wall.

[0059] Optionally, the first driving member 311 may further include a swing rod and a motor, the motor drives the swing rod to swing, and the swing rod drives the pressing plate 312 to swing.

[0060] Continue reading Figure 4 The second clamping assembly 32 includes a second driving member 321 and a clamping crank arm 322. The second driving member 321 is connected to the clamping crank arm 322 and is used to drive the clamping crank arm 322 to swing between the third position and the fourth position; wherein, when the clamping crank arm 322 is in the third position, one end of the clamping crank arm 322 is located between the anti-flooding baffle 12 and the rolling shutter piece 11, and applies a clamping force to the plurality of anti-flooding baffles 12 in a vertical direction; when the clamping crank arm 322 is in the fourth position, the clamping crank arm 322 is located on the same side of the rolling shutter piece 11 and the anti-flooding baffle 12 and is spaced apart from the anti-flooding baffle 12.

[0061] The second driving member 321 is an electric push rod, and the clamping crank arm 322 includes a first crank arm and a second crank arm that are bent and connected. The connection between the first crank arm and the second crank arm is also rotatably connected to another fixed seat. The electric push rod is rotatably connected to the first crank arm, thereby driving the second crank arm to swing. When the clamping crank arm 322 is in the third position, the second crank arm is located between the anti-flooding baffle 12 and the rolling shutter piece 11 and applies a clamping force to the anti-flooding baffle 12. When the clamping crank arm 322 is in the fourth position, the second crank arm is located on the same side of the rolling shutter piece 11 and the clamping force applied to the anti-flooding baffle 12 is released, and the rolling shutter assembly 10 is allowed to move along the vertical slide rail 40.

[0062] Optionally, the second driving member 321 may also be a motor or include a motor and a reduction mechanism.

[0063] Combined with reference Figure 1 and Figure 5 , Figure 6 , Figure 5 yes Figure 1 The partial structural diagram of the flood-proof rolling shutter door is shown in FIG. Figure 6 yes Figure 5 Schematic diagram of the top view of the structure shown.

[0064] In this embodiment, the flood-proof rolling shutter door 100 also includes an anti-falling mechanism 50, which is connected to the vertical slide rail 40. The anti-falling mechanism 50 includes a shift rod 51, which can move between a stop position and a lifting position; wherein, the shift rod 51 is in the stop position to prevent the rolling shutter assembly 10 from passing through, and the shift rod 51 is in the lifting position to allow the rolling shutter assembly 10 to pass through.

[0065] like Figure 5 As shown, the gear lever 51 drawn with a solid line is located at the stop position, and the gear lever 51 drawn with a dotted line is located at the lifting position. The solid line and the dotted line respectively reflect the postures of the gear lever 51 at different positions.

[0066] The anti-falling mechanism 50 is arranged at the upper end of the vertical slide rail 40. After the rolling shutter assembly 10 is rolled up, its stop rod 51 is in the stop position to prevent the rolling shutter assembly 10 from passing through and prevent the rolling shutter assembly 10 from falling due to a malfunction, thereby further increasing the safety of the flood-proof rolling shutter door 100, and can effectively reduce the falling risk of the rolling shutter assembly 10 and reduce the probability of pedestrians being injured.

[0067] When the rolling shutter assembly 10 actively descends, the stop bar 51 first moves from the stop position to the lifting position to allow the rolling shutter assembly 10 to pass through and slide along the vertical slide rail 40 .

[0068] Optionally, the shift lever 51 can move between the stop position and the lifting position by swinging or sliding.

[0069] In this embodiment, the anti-fall mechanism 50 also includes a limit plate 52 and an electric push rod 53. The limit plate 52 is connected to the vertical slide rail 40. One end of the shift rod 51 is rotatably connected to the vertical slide rail 40, and the shift rod 51 can be supported on the limit plate 52 under its own weight and be located in the stop position; the electric push rod 53 is used to push the shift rod 51 so that it rotates from the stop position to the lifting position.

[0070] The limit plate 52 is used to define the stop position and provide supporting force to the lever 51, so that the lever 51 can be reliably positioned on the limit plate 52, and when the rolling shutter assembly 10 falls accidentally, it can provide sufficient supporting force to the lever 51 to prevent the rolling shutter assembly 10 from falling further.

[0071] Among them, the electric push rod 53 provides a thrust force, so that the gear rod 51 rotates from the stop position to the lifting position; and after the electric push rod 53 stops providing the thrust force, the gear rod 51 can fall back from the lifting position to the stop position under its own weight. Its action is efficient and reduces the accuracy requirements on the electric push rod 53, thereby reducing costs.

[0072] Furthermore, the other end of the lever 51 is also connected to a roller 54, which can offset the center of gravity of the combination with the lever 51 to increase the efficiency of the lever 51 falling back, and when the lever 51 is in the raised position, when the rolling shutter assembly 10 collides with the lever 51, the roller 54 can also provide rolling contact to reduce the collision interference of the lever 51 on the rolling shutter assembly 10, so that the rolling shutter assembly 10 can run more smoothly.

[0073] In this embodiment, the anti-fall mechanism 50 also includes an axle bracket 55 and a rotating shaft 56. The axle bracket 55 is connected to the vertical slide rail 40, and the rotating shaft 56 is rotatably installed on the axle bracket 55. One end of the gear lever 51 is connected to the rotating shaft 56. The electric push rod 53 is connected to one side of the axle bracket 55 and is used to drive the rotating shaft 56 to rotate.

[0074] The shaft bracket 55 is connected to the inner side of the vertical slide rail 40, and provides two rotational installation positions for the rotating shaft 56. The shaft bracket 55 includes two L-shaped adapter plates, which are connected to the vertical slide rail 40, and the rotating shaft 56 is rotatably connected to the two L-shaped adapter plates. One end of the gear lever 51 is connected to the rotating shaft 56, and the gear lever 51 rotates with the rotating shaft 56, and the electric push rod 53 drives the rotating shaft 56 to rotate.

[0075] The rotating shaft 56 is provided with a connecting piece 57, and the electric push rod 53 is used to push the connecting piece 57, thereby driving the rotating shaft 56 to rotate. By providing the connecting piece 57, the way in which the electric push rod 53 drives the rotating shaft 56 is simplified, and the structure is simple.

[0076] Through the above-mentioned method, a simple structure of the anti-fall mechanism 50 is achieved, and the action efficiency is high and the required cost is relatively low.
