Description

Technical Field

[0001] This utility model relates to a roller shutter door, specifically a roller shutter door with a water baffle. Background Technology

[0002] Subway station entrances are typically equipped with roller shutters to close the entrances when the subway is not in operation. However, these roller shutters only provide basic protection, and during heavy rains, floodwaters can easily flow back into the subway station through the entrances.

[0003] To prevent rainwater from flowing back into the subway, current technologies typically involve stacking sandbags or placing flood barriers. However, in practice, these methods require manual handling, which is inefficient, and storing sandbags or flood barriers takes up space and obstructs pedestrian traffic. Utility Model Content

[0004] The purpose of this utility model is to provide a roller shutter door with a water baffle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roller shutter door with a water-blocking plate is installed inside a doorway. It includes a roller shutter composed of multiple curtain panels connected in series and a winding and unwinding component located at the top of the doorway for winding and unwinding the roller shutter. A water-blocking plate is provided at the end of the roller shutter away from the winding and unwinding component. Tracks are provided on both sides of the doorway for the roller shutter and the water-blocking plate to move up and down. When the roller shutter is unwinding until the water-blocking plate descends to the ground, the water-blocking plate can block water from the lower part of the doorway. When the roller shutter is winding up, the water-blocking plate can rise with the roller shutter to the top of the doorway without affecting the passage of people and vehicles inside the doorway.

[0007] Preferably, the roller shutter and the water baffle are separable. When the water baffle falls to the ground to block water from the lower part of the doorway, the roller shutter can be rolled up separately to the upper part of the doorway, so that the roller shutter door remains passable while blocking water.

[0008] Preferably, the water baffle is detachably connected to the roller shutter.

[0009] Preferably, it also includes a counterweight mechanism for balancing part or all of the weight of the baffle, reducing the load on the roll-up and roll-down components when the roller shutter drives the baffle to rise and fall.

[0010] Preferably, the counterweight mechanism is configured such that when the baffle is separated from the roller shutter, the baffle can fall freely to the ground.

[0011] Preferably, the counterweight mechanism is a sling counterweight mechanism.

[0012] Preferably, the counterweight mechanism includes a counterweight block and a pulley block installed at the doorway. The counterweight block and the flood barrier or the counterweight block and the roller shutter are connected by a traction rope that passes around the pulley block. When the flood barrier descends, the counterweight block rises, and when the flood barrier rises, the counterweight block descends.

[0013] Preferably, the water baffle also includes a second water baffle that is detachably connected to the side of the water baffle. When the water baffle falls to the ground and the roller shutter is separated from the water baffle, the second water baffle can be removed and inserted into the top of the water baffle to increase the water baffle height.

[0014] Preferably, the tracks on both sides of the doorway are side guide tracks shared by the roller shutter and the water baffle. By modifying the existing roller shutter door, the door structure does not need to be rebuilt when installing the water baffle, resulting in low modification costs.

[0015] Preferably, the bottom of the baffle is provided with a lower sealing component, and the two ends of the baffle and the two side walls of the doorway are provided with side sealing components; when the baffle falls to the ground, the bottom of the baffle and the ground are sealed by the lower sealing component, and the two ends of the baffle and the two side walls of the doorway are sealed by the side sealing components.

[0016] Preferably, the side sealing component includes a vertical back plate disposed on the back surface of the baffle plate; when the baffle plate blocks water, the back plate supports the baffle plate, increasing the water-blocking strength of the baffle plate.

[0017] Preferably, the side sealing component further includes a thrust mechanism that pushes the baffle plate against the back plate, thereby making the baffle plate fit tightly against the back plate and achieving a seal between the baffle plate and the back plate.

[0018] The distance between the opposing surfaces of the front plate and the back plate is greater than the thickness of the baffle plate.

[0019] The distance between the front plate and the back plate protruding from the door opening sidewall is greater than the distance between the side guide rail and the door opening sidewall.

[0020] Preferably, the thickness of the baffle plate is greater than the thickness of the roller blind, and both ends of the roller blind are inserted into the side guide rails so that the roller blind can move up and down along the side guide rails; both ends of the baffle plate are provided with connectors, and the connectors at both ends of the baffle plate are inserted into the side guide rails so that the baffle plate can move up and down along the side guide rails.

[0021] Preferably, the two ends of the baffle plate are connected to the side guide rail through connectors to form an elastic connection. When the water-facing surface of the baffle plate is subjected to pressure, the baffle plate can move horizontally along the water pressure direction until the back surface of the baffle plate is tightly attached to the back plate. When the pressure is removed, the baffle plate can automatically return to its original position.

[0022] Preferably, the water-facing and / or back-facing surfaces of the water-blocking plate are equipped with advertising modules.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This application utilizes the existing roller shutter door for water blocking modification. By setting up a counterweight mechanism, the water blocking plate only slightly increases the load on the original rolling mechanism. It can be achieved by adding a water blocking plate to the bottom of the existing roller shutter without rebuilding the original door structure, resulting in low modification costs.

[0025] 2. When blocking water, this application simply lowers the water barrier to the ground. Compared with the existing technology of transporting sandbags to block water, this application has a faster water blocking response speed and higher efficiency. Moreover, the water barrier does not occupy passage space and does not affect pedestrian passage.

[0026] 3. The bottom of the roller shutter of this application is equipped with a water baffle. When the roller shutter is unrolled until the water baffle descends to the ground, the door opening can be closed. It can be used to block water and also has the protective function of an ordinary roller shutter door.

[0027] 4. The water barrier of this application can rise to the top of the doorway with the roller shutter, without affecting the passage of people and vehicles inside the doorway. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] A roller shutter door with a water baffle is installed inside a doorway. It includes a roller shutter 1 composed of multiple curtain panels connected in series and a rolling and unrolling component 2 installed at the top of the doorway for rolling up and unrolling the roller shutter 1. A water baffle 3 is connected to the end of the roller shutter 1 away from the rolling and unrolling component 2. Tracks are provided on both sides of the doorway for the roller shutter 1 and the water baffle 3 to move up and down.

[0041] Based on the above scheme, this application can have the following two working states;

[0042] like Figure 1 As shown, the roller shutter 1 rolls down until the water baffle 3 falls to the ground, at which point the roller shutter 1 and the water baffle 3 close the doorway.

[0043] like Figure 2 As shown, when the roller shutter 1 rolls up, the water baffle 3 rises synchronously with the roller shutter 1 to the upper part of the doorway, without affecting the passage of people and vehicles inside the doorway.

[0044] Example 2

[0045] While the above solutions can achieve the function of blocking water, the doorway is closed when water is blocked, making it impossible to pass through. This reduces the practicality of the roller shutter door with a water barrier.

[0046] Therefore, we designed such as Figure 3 As shown, the structure between the water baffle 3 and the roller shutter 1 is separable. When the water baffle 3 falls to the ground to block water, the roller shutter 1 can rest against the top of the water baffle 3, or after the roller shutter 1 separates from the water baffle 3, the roller shutter 1 can be rolled up separately to the top of the doorway.

[0047] Furthermore, the water baffle 3 and the roller shutter 1 can be connected by a detachable structure.

[0048] It should be noted that the detachable structure of the water baffle 3 and the roller shutter 1 can be fixed by bolts or by snap-fit. This detachable structure is a mature existing technology and will not be described in detail here.

[0049] The water-blocking height of the baffle plate 3 is 200-1000mm, preferably 200-600mm.

[0050] Specifically, the water barrier 3 is made of at least one aluminum alloy profile with a height of 200mm spliced ​​along the height direction, so that the water barrier height of the water barrier 3 can be an integer multiple of 200mm. Preferably, the water barrier 3 is made of three aluminum alloy profiles spliced ​​together. When the water barrier height does not exceed 600mm, it hardly affects the passage of pedestrians.

[0051] Example 3

[0052] Although the detachable design between the water baffle 3 and the roller shutter 1 allows the water baffle 3 to be lowered to the ground independently for water blocking, the weight of the water baffle 3 itself increases the load on the winding and unwinding assembly 2 when the roller shutter is being wound up. Therefore, we have installed a counterweight mechanism for the water baffle 3. This counterweight mechanism is a cable-type counterweight structure, which can be used to balance part or all of the weight of the water baffle 3, reducing the load on the winding and unwinding assembly 2 when the roller shutter 1 moves the water baffle 3 up and down.

[0053] Since existing roller shutters can provide a large force when rolling up, and the roller shutter generally falls freely under its own weight when unrolling, in this embodiment, the counterweight mechanism is configured such that when the baffle 3 is separated from the roller shutter 1, the baffle 3 can fall freely to the ground.

[0054] In the design of existing roller shutters, the driving force provided by the rolling mechanism must be greater than the weight of the roller shutter itself to ensure the rolling function. This application utilizes the existing roller shutter for water-blocking modification. By setting up a counterweight mechanism, the water-blocking plate 3 only slightly increases the load on the original rolling mechanism. It can be done without rebuilding the original door structure, and the water-blocking plate can be added to the bottom of the original roller shutter, resulting in low modification cost.

[0055] Example 4

[0056] In the above scheme, the water baffle 3 cannot be raised or lowered independently; it can only rely on the roller shutter 1 to raise or lower. Every time the water baffle is raised or lowered after the water baffle is raised, the roller shutter 1 must be lowered first, then the water baffle 3 must be fixed to the bottom of the roller shutter 1, and then the roller shutter 1 must be raised. The operation is still somewhat complicated and inconvenient to use.

[0057] To solve the above problems, we designed the water baffle 3 to be raised and lowered independently, which makes the operation of raising and lowering the water baffle 3 more convenient and quick.

[0058] Based on this scheme, we can set up a separate lifting drive for the baffle plate 3. When the roller shutter 1 is rolled up to the top of the doorway, the baffle plate 3 is driven to rise independently. This lifting drive can be an existing winch, and the technology of using a winch to drive the lifting of heavy objects through a pulley system is a mature existing technology. Professionals in this field can set it up according to the actual situation, which will not be elaborated here.

[0059] Furthermore, the counterweight mechanism in Embodiments 3 and 4 includes a counterweight 10 and a pulley system installed at the doorway. The counterweight 10 and the baffle 3 or the counterweight 10 and the roller shutter 1 are connected by a traction rope 12 that passes around the pulley system. When the baffle 3 descends, the counterweight 10 rises, and when the baffle 3 rises, the counterweight 10 descends.

[0060] For preferred options, please refer to [link / reference]. Figure 4 The pulley system includes fixed pulleys 11 set at the top of both sides of the doorway, counterweight 10 set on one side of the doorway, and the ends of the traction rope 12 fixedly connected to both ends of the water baffle 3. The traction rope 12 passes around the fixed pulleys 11 and is connected to the counterweight 10.

[0061] When installing the fixed pulley 11, the fixed pulley 11 can be directly fixed to the side wall of the doorway using bolts and brackets.

[0062] It should be noted that the counterweight mechanism can also be configured with counterweight blocks on both sides of the doorway, but considering that the synchronization of the two ends of the water baffle 3 of the counterweight blocks is poor when configured in this way, it is not preferred; and the pulley group can be a pulley group formed by several movable pulleys and several fixed pulleys for different purposes. This technology is a mature technology in the field and will not be described in detail here.

[0063] Furthermore, a guide rail for the counterweight 10 can be fixed to the side wall of the doorway to conceal the counterweight 10, thereby improving the stability and aesthetics of the counterweight 10 during its lifting and lowering process.

[0064] In addition, a lower latch mechanism is installed at the bottom of the doorway. When the water baffle 3 falls to the ground, the lower latch mechanism locks the water baffle 3 to prevent it from being pulled up by the counterweight mechanism. An upper latch mechanism is installed at the top of the doorway to prevent the water baffle 3 from falling and to improve the safety of the water baffle 3.

[0065] It should be noted that the pin mechanism can be a common pin structure in the existing technology. Those skilled in the art can freely set it according to the actual situation, and its specific structure will not be described in detail here.

[0066] Example 5

[0067] Please see Figure 3 and Figure 5Since this application utilizes an existing roller shutter door for modification, the height of the doorway is fixed from the beginning. Furthermore, the baffle 3 cannot be retracted into the original rolling mechanism. When the baffle 3 rises to the top of the doorway, it hangs precariously inside. Therefore, the height of the baffle 3 cannot be set too high; otherwise, the hanging portion will obstruct the passage of people and vehicles within the doorway. However, in some environments, the required water-blocking height cannot be too low. Therefore, we consider installing at least one detachable second baffle 31 on the side of the existing baffle. When the baffle 3 is lowered to the ground, and the roller shutter 1 is separated from the baffle 3, the second baffle 31 can be removed and inserted into the top of the baffle 3 to increase the water-blocking height. This ensures the water-blocking height while preventing the baffle 3 from obstructing the passage of people and vehicles when it rises to the top of the doorway.

[0068] Similar to the water baffle 3, the second water baffle 31 is also spliced ​​together from at least one aluminum alloy profile with a height of 200mm along the height direction. Preferably, it consists of two aluminum alloy profiles spliced ​​together to form a second water baffle 31 with a height of 400mm.

[0069] Furthermore, since the second baffle plate 31 is located above the baffle plate 3, the water pressure on the second baffle plate 31 is significantly less than that on the baffle plate 3 when blocking water. Therefore, in the design, the profile thickness of the second baffle plate 31 can be made slightly thinner than that of the baffle plate 3, so that the second baffle plate 31 is lighter than the baffle plate 3 at the same height, thereby reducing the overall weight of the second baffle plate 31 and the baffle plate 3.

[0070] It should be noted that the insertion structure between the second baffle plate 31 and the baffle plate 3 is a mechanical structure that is easily conceived by those skilled in the art, and will not be described in detail here.

[0071] Please see Figure 7 When the second baffle plate 31 is inserted into the baffle plate 3, the roller shutter 1 can be unrolled and lowered until it reaches the top of the second baffle plate 31.

[0072] Example 6

[0073] When blocking water, the sealing of the water-blocking plate 3 also needs to be considered. A lower sealing component is provided at the bottom of the water-blocking plate 3, and a side sealing component is provided between the two ends of the water-blocking plate 3 and the two side walls of the doorway. When the water-blocking plate 3 falls to the ground, the lower sealing component seals the bottom of the water-blocking plate 3 and the ground, and the side sealing component seals the two ends of the water-blocking plate 3 and the two side walls of the doorway.

[0074] Specifically, the lower sealing component includes a pressing mechanism for pressing down the baffle plate 3. After the baffle plate 3 lands, the pressing mechanism presses the baffle plate 3 onto the ground to achieve a seal between the bottom of the baffle plate 3 and the ground.

[0075] The side sealing component includes a vertical back plate 5 disposed on the back surface of the baffle plate 3; when the baffle plate 3 blocks water, the back plate 5 supports the baffle plate 3.

[0076] The side sealing component also includes a thrust mechanism that pushes the baffle plate 3 toward the back plate 5, so that the baffle plate 3 is tightly attached to the back plate 5, thereby achieving a seal between the baffle plate 3 and the back plate 5.

[0077] To improve the sealing between the back plate 5 and the baffle 3, and between the baffle 3 and the ground, sealing strips can be installed on the side of the back plate 5 facing the baffle 3, the position of the back side of the baffle 3 corresponding to the back plate 5, and the bottom surface of the baffle 3.

[0078] The thrust mechanism is installed on the vertical forward plate 6 located on the water-facing side of the baffle plate 3.

[0079] The distance between the opposing surfaces of the front plate 6 and the back plate 5 is greater than the thickness of the baffle plate 3.

[0080] The distance between the front plate 6 and the back plate 5 protruding from the door opening side wall is greater than the distance between the side guide rail 4 protruding from the door opening side wall.

[0081] Both the front plate 6 and the back plate 5 are provided with inclined guide plates at the top. The two guide plates at the top of the front plate 6 and the back plate 5 gradually open from bottom to top to form an inverted "eight" shaped guide opening. The guide opening is used to guide the water baffle 3 during its descent to prevent the water baffle 3 from being stuck.

[0082] Please see Figure 5 and Figure 6 Preferably, the thrust mechanism includes a front plate 6 disposed on the water-facing surface of the baffle plate 3. The front plate 6 is provided with a plurality of thrust knobs 7 that can push the baffle plate 3 toward the back plate 5. The thrust knobs 7 are threadedly connected to the front plate 6 perpendicular to the water-facing surface of the baffle plate 3.

[0083] In addition to the above solutions, the thrust mechanism can also utilize power mechanisms such as airbags and cylinders to push the baffle plate 3 towards the back plate. These mechanisms are structures that are easy for those skilled in the art to conceive of, and will not be listed one by one here.

[0084] Specifically, the back plate 5 and the front plate 6 can be directly fixed to the side wall of the door opening with expansion bolts. When blocking water, the back plate 5 supports the water-blocking plate 3, and the force is directly transmitted to the side wall, which is highly reliable. In addition, the back plate 5 and the side wall are sealed together.

[0085] The pressing mechanism includes a swing arm 8 mounted on the front plate 6. One end of the swing arm 8 is hinged to the front plate 6, and the other end is threaded with a vertical pressing knob 9. When the end of the swing arm 8 with the pressing knob 9 is swung above the baffle plate 3, the baffle plate 3 can be pressed down by the pressing knob 9.

[0086] Furthermore, at least one set of pressing mechanisms is provided, the number of which corresponds one-to-one with the preset water-blocking heights formed by the combination of the water-blocking plate 3 and the second water-blocking plate 31. When the water-blocking plate 3 and the second water-blocking plate 31 are connected to form N water-blocking heights, N sets of pressing mechanisms are provided.

[0087] Example 7

[0088] The tracks on both sides of the doorway are used for the roller shutter 1 and the baffle 3 to move up and down. The solution in this application is an improvement on the existing roller shutter door. Therefore, in the design, the track is the side guide rail 4 shared by the roller shutter 1 and the baffle 3.

[0089] Please see Figure 8 and Figure 9 Because the water baffle 3 needs to have high strength, the thickness of the water baffle 3 needs to be greater than the thickness of the roller shutter 1. Both ends of the roller shutter 1 can be inserted into the side guide rail 4 so that the roller shutter 1 can move up and down along the side guide rail 4. Both ends of the water baffle 3 are provided with connectors 13, which are inserted into the side guide rail 4 so that the water baffle 3 can move up and down along the side guide rail 4.

[0090] According to the aforementioned scheme, the water-facing surface of the baffle 3 needs to be tightly attached to the back plate 5 after being subjected to pressure. Therefore, the connector 13 needs to have the following characteristics: the two ends of the baffle 3 can be connected to the side guide rail 4 through the connector 13 to form an elastic connection. When the water-facing surface of the baffle 3 is subjected to pressure, the baffle 3 can move horizontally along the water pressure direction until the back surface of the baffle 3 is tightly attached to the back plate 5. When the pressure is removed, the baffle 3 can automatically return to its original position.

[0091] For details, please refer to Figure 10 The connector 13 includes a plug-in plate 135 that is plugged into and fixed to the end of the baffle plate 3. The plug-in plate 135 is provided with a connecting pin 134 arranged along the length of the baffle plate 3. The plug-in plate 135 has a through hole 132 for the connecting pin 134 to pass through the plug-in plate 135, and the inner diameter of the through hole 132 is larger than the diameter of the connecting pin 134. One end of the connecting pin 134 is fixedly connected to a protrusion 131 that can be inserted into the side guide rail 4. The diameter of the protrusion 131 is larger than the inner diameter of the through hole 132. It is smaller than the width of the slide inside the side guide rail 4. The other end of the connecting pin 134 is fixed with a limit block. A spring 133 is sleeved on the connecting pin 134 between the limit block and the plug plate 135. When the baffle plate 3 is pressed, the connecting pin 134 can tilt within a limited angle in the through hole 132. At this time, the baffle plate 3 can be displaced in the horizontal direction accordingly. When the pressure is removed, the connecting pin 134 is reset under the action of the spring 133, and the baffle plate 3 can automatically return to its original position.

[0092] The water-facing and / or back-facing surfaces of the water-blocking plate 3 are equipped with advertising modules (not shown in the figure). These advertising modules include, but are not limited to, existing billboards, advertising screens, advertising machines, and other equipment. Since these are existing devices, they will not be described in detail here.

[0093] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the contents not described in detail in this specification are all prior art known to those skilled in the art.
