Description

Technical Field

[0001] The present invention relates to the technical field related to protective equipment, and more specifically, to an automatic sealing flood-proof rolling shutter door. Background Art

[0002] The urban underground space and the ground space are connected through various vertical connecting ports, including pedestrian staircase entrances and exits, motor vehicle and non-motor vehicle ramp exits, fire stairs, barrier-free elevators, ventilation shafts, light wells, sunken passages, etc., and emergency escape hatches in civil defense projects. In addition to meeting daily use functions, various connecting ports in underground spaces must also have disaster prevention functions. In an emergency, the exit is the only way to escape from the disaster area and enter the ground. When a disaster occurs in the ground space outside the underground space, the connecting port plays a role in preventing the disaster from spreading underground. Therefore, the connecting port bears a major responsibility for disaster prevention and can play a role in disaster prevention zoning, evacuation guidance, and vertical evacuation. For underground spaces affected by floods and waterlogging, the connecting ports between underground space and the ground mainly play a role in preventing surface floods and waterlogging from entering the underground space.

[0003] The design of underground space connections is mainly considered from the perspectives of function, safety and environment. The plane layout and scale of the connection are mainly considered from the functional planning requirements. The environment is mainly considered to be integrated with the ground space and connected buildings. The safety is mainly considered in peacetime protection and wartime protection. Peacetime protection is mainly fire prevention. For flood prevention, the main method is to prevent the intrusion of ground water by designing a certain water retaining height at each connection. The requirements for underground space flood control and water retaining safety settings for connection ports are stipulated in many specifications. These specifications all mention underground space flood control and water retaining measures, but their requirements are not consistent. The flood control standards of underground space and ground space cannot be matched and unified. Among many specifications, the water retaining height requirements range from 150 ~ There is a big difference between 1250mm and 1250mm, which causes great difficulties in actual design and construction.

[0004] In recent years, the existing main flood prevention measures in underground spaces have frequently failed, and additional flood prevention measures need to be taken to deal with flooding situations. Flood prevention measures are often carried out by arranging flood prevention sandbags and water retaining boards. This method requires a large number of personnel to be deployed, and there are problems such as high management difficulty and low operating efficiency. The most important thing for flood prevention in underground spaces is to prevent water from flowing into underground spaces. There are many connecting openings between underground spaces and ground spaces, among which the entrances and exits of underground space stations are the most important. The existing underground space and other underground space entrances and exits civil air defense doors are installed in the civil air defense protection section of the station entrance and exit passages. They do not take into account the flood prevention function of the underground space and cannot achieve waterproofing of surface floods.

[0005] In the existing technology, the installation of water retaining gates and gate slots at the entrances and exits of urban underground spaces is one of the most effective emergency measures to prevent ground water from invading underground spaces. Especially for vehicle and personnel entrances and exits, from the perspective of functional use, vehicle and personnel entrances and exits are different from the connecting ports such as ventilation shafts and light wells. Since vehicles and personnel need to travel together, it is often difficult to reach the flood prevention elevation at one time. Under this premise, a two-level defense system is adopted, with steps and humps as the first-level water retaining structure to ensure that surface water with shallow water accumulation will not enter the underground space during daily operation. During floods, steps and humps can also play a good buffering role, buying time for emergency rescue and the transportation and installation of equipment and materials. The water retaining gate is used as the second-level water retaining structure. According to meteorological warnings, forecasts or external flood development trends, it is installed or closed in time to form an effective water retaining system together with the first-level water retaining. At present, flood gates can be made of sandbags, water-filled rubber bags, wooden boards, metal gates and other materials. In China, the most commonly used method for underground spaces is temporary stacking of sandbags. Due to urbanization, the daily management and stacking of sandbags are inconvenient in some areas. Summary of the invention

[0006] 1. Technical issues

[0038] Please refer to Figures 1 to 4 ,in, Figure 1This is a front view of an automatic sealing flood-proof rolling shutter door in an embodiment of the present invention; Figure 2 It is a side cross-sectional view of an automatic sealing flood-proof rolling shutter door in an embodiment of the present invention; Figure 3 for Figure 2 An enlarged schematic diagram of the structure at the middle box a; Figure 4 Schematic diagram of the structure of the door track in an embodiment of the present invention.

[0039] The invention provides an automatic sealing flood-proof rolling shutter door with automatic waterproofing function. The automatic sealing flood-proof rolling shutter door provided by the invention belongs to an electric panel rolling shutter door, which can also be understood as a structure similar to a blind that can be waterproof. The flood-proof height of the invention can reach 3.0 meters, and under normal circumstances, it can also be used as a rolling shutter door for daily use, making it an ideal equipment for flood protection at the entrance and exit of subways and underground shopping malls.

[0040] The present invention provides an automatic sealing flood-proof rolling shutter door, which is arranged before the entrance and exit connecting the underground space with the surface space (along the "exit" direction of the entrance and exit, the automatic sealing flood-proof rolling shutter door is arranged before the entrance and exit), and is used for automatically closing the entrance and exit when flooding occurs on the surface, thereby realizing automatic flood prevention of the entrance and exit (preventing surface flooding from flowing back into the underground space).

[0041] In the present invention, the automatic sealing flood-proof rolling shutter door mainly includes two parts: 1. The rolling shutter door can be unfolded according to the flood situation of the surface space to realize the closing of the entrance and exit and flood prevention. The rolling shutter door is a complete door leaf system and can be automatically rolled up. The rolling up can be remotely controlled or locally controlled to realize mechanized rolling up, or it can be automatically rolled up through a variety of sensors and controllers, or it can be manually rolled up by an operator; 2. The door frame system, the door frame system and the rolling shutter door are a watertight matching structure, and the door frame system is fixedly arranged relative to the entrance and exit. Specifically, the door frame system can be fixedly installed on the building foundation and is located before the entrance and exit. The door frame system is mainly used to cooperate with the rolling shutter door. After the rolling shutter door is unfolded, it forms a sealed barrier with the rolling shutter door to prevent flood water in the surface space from flowing back into the underground space through the entrance and exit. The present invention can be activated to close the entrance and exit when a flood disaster occurs in the surface space and before the flood water flows back into the underground space. In addition, in non-flood situations, the rolling shutter door can be retracted to open the entrance and exit.

[0042] In order to realize automatic control of the rolling door, the automatic sealed flood-proof rolling door includes an automatic control system, and the automatic control system includes a PIC microcontroller that can be connected to the field inherent control system (for example, the present invention is applied to the subway system, and the field inherent control system of the subway system includes the subway environment and equipment monitoring system, i.e., the BAS system). The PIC microcontroller includes multiple communication ports, one of which is connected to the field inherent control system for communication, and the others are connected to different sensors and controlled devices (the power unit 5 of the rolling door). A liquid level sensor 1 is signal-connected to the PIC microcontroller. Specifically, the liquid level sensor 1 is connected to the PIC microcontroller through a signal line. The liquid level sensor 1 is arranged in the outward space of the rolling door and is used to monitor the flood water level height outside the rolling door. The liquid level sensor 1 monitors continuously according to the set time. When a flood disaster occurs in the surface space, the water level rises and submerges the liquid level sensor 1. The liquid level sensor 1 sends a monitoring signal to the PIC microcontroller. The PIC microcontroller is connected to the rolling door control. It (the PIC microcontroller) can automatically control the start-up of the rolling door according to the monitoring signal of the liquid level sensor 1, thereby controlling the start-up and deployment of the rolling door when a flood disaster occurs in the surface space.

[0043] When the rolling door is unfolded, if there is an obstacle within its unfolding range, the unfolding of the rolling door will be affected by the obstacle, and in serious cases, the rolling door may be damaged (for example, the rolling door is driven to unfold by the power device 5, and at the same time cannot be fully unfolded due to the obstacle, then the rolling door will be subjected to a bidirectional force, and once the force is too large, the rolling door will be structurally damaged). In order to avoid the above situation, the present invention further adds an infrared sensor 2 in the automatic control system, and the infrared sensor 2 is set at the edge of the range that can ensure the smooth unfolding of the rolling door, and the infrared sensor 2 monitors the possible obstacles, and the infrared sensor 2 is connected to the PIC microcontroller signal. The infrared sensor 2 is set in the inner space of the rolling door and is used to monitor the presence of foreign objects in the opening range of the rolling door (the opening range refers to a virtual space concept that ensures the smooth opening of the rolling door). The PIC microcontroller automatically controls the start of the rolling door according to the monitoring signal of the infrared sensor 2. In addition, the automatic control system also includes an alarm 3, which is connected to the PIC microcontroller for alarming during the start-up process of the rolling door. Specifically, the alarm 3 is a buzzer and / or an alarm light.

[0044] In the present invention, the specific structure of the rolling door is as follows: it includes a door leaf assembly 4 and a driving assembly, the driving assembly is arranged at the top of the door frame system, the driving assembly includes a power device 5 and a reel 6 (the present invention is provided with a rolling shutter box, the reel 6 is rotatably arranged in the rolling shutter box, the power device 5 is a motor, the power device 5 is arranged in the rolling shutter box, and the power device 5 is connected to the reel 6 through a traditional system to drive the reel 6 to rotate), the door leaf assembly 4 can be rolled up onto the reel 6; the door leaf assembly 4 includes a door leaf unit 7, a plurality of door leaf units 7 are provided, adjacent door leaf units 7 are hinged and can be flipped toward the same side to realize the rolling of the door leaf assembly 4 on the reel 6, and a compressible water stop strip 8 is provided between adjacent door leaf units 7. After the door leaf assembly 4 is unfolded, the compressed water stop strip 8 between adjacent door leaf units 7 is deformed to achieve watertight cooperation between the door leaf units 7, and the water stop strip 8 is fixedly connected to the upper edge or lower edge of the door leaf unit 7. The door leaf assembly 4 is similar to the traditional rolling door leaf structure in the prior art. In addition, the present invention further optimizes the structure of the door leaf unit 7: a matching edge is provided on the bottom surface of the door leaf unit 7 and along the length direction of the door leaf unit 7 (generally speaking, the span direction of the entrance and exit), and the matching edge is preferably a sharp angle structure (it can also be an isosceles trapezoidal structure or a circular arc convex structure), and the matching edge is provided in the middle position of the width direction of the door leaf unit 7 (generally speaking, the depth direction of the entrance and exit), and a matching groove adapted to the shape of the matching edge is provided on the top surface of the door leaf unit 7. After the door leaf assembly 4 is unfolded, the matching edges and matching grooves between two adjacent door leaf units 7 can be "assembled" together, so that the tightness of the assembly between adjacent door leaf units 7 can be improved, and the door leaf units 7 can be limited (so that all door leaf units 7 can be located in the same plane). The present invention provides a water stop strip 8 on the upper edge or lower edge of the door leaf unit 7, and the water stop strip 8 is designed according to the shape of the upper edge or lower edge of the door leaf unit 7. Furthermore, a bottom rubber strip 9 is provided at the bottom of the door leaf assembly 4, and a sealing strip that cooperates with the bottom rubber strip 9 is fixedly provided on the ground of the entrance and exit, and the bottom rubber strip 9 can be abutted against the sealing strip to achieve the bottom sealing of the door leaf assembly 4 (the bottom seal is a metal profile, and its upper side is designed as a flat structure, which can contact with the bottom rubber strip 9). In order to increase the deformability and elasticity of the bottom rubber strip 9, the present invention is provided with an airbag structure on the bottom rubber strip 9. The airbag structure has high compressibility and can produce a large deformation after the bottom rubber strip 9 contacts the bottom seal, thereby improving the water tightness of the bottom edge after the rolling door is closed.

[0045] As for the door frame system, the door frame system includes a door rail 10 fixedly arranged relative to the entrance and exit. The door rail 10 is a metal component and is fixed to the building (which can be an existing building or a newly built building as needed) by expansion bolts. The door rail 10 includes a vertically arranged door rail groove 11. The door rail 10 includes two door rails 10, which are vertically and spaced apart. The door rail grooves 11 of the two door rails 10 are arranged oppositely. A rolling shutter box is arranged on the top of the two door rails 10. The side of the door leaf assembly 4 is assembled in the door rail groove 11. A door rail sealing strip 12 is arranged in the door rail groove 11 (after the door leaf assembly 4 is unfolded, the door leaf assembly 4 is opened). The inner side surface of the side of the component 4 is in contact with the door rail sealing strip 12 to achieve a sealed connection), and the role of arranging the door rail sealing strip 12 in the door rail groove 11 is: the door rail 10 achieves watertight contact with the inner side surface of the door leaf component 4 through the door rail sealing strip 12, and a pressing device 13 for pressing the side of the door leaf component 4 is also arranged in the door rail groove 11. The pressing device 13 can be against the outer side surface of the door leaf component 4. The pressing device 13 can be a roller elastically installed on the door rail 10, and the roller is in rolling contact with the door leaf component 4. During the contact process, pressure is applied to the door leaf component 4, thereby improving the sealing between the door leaf component 4 and the door rail 10.

[0046] In order to improve the sealing performance of the entire door leaf assembly 4 (specifically, to improve the tightness of the fit between adjacent door leaf units 7), the present invention further provides an adjusting device 14 for adjusting the pressure of the unfolded rolling door, and the adjusting device 14 is at least used to adjust the vertical pressure of the rolling door. Specifically, the adjusting device 14 includes a vertical adjusting device 14 and a vertical adjusting device 14. The vertical adjusting device 14 can be connected to the top of the rolling door and is used to apply a top-down pressure to the rolling door to compress the door leaf assembly 4 of the rolling door. The vertical adjusting device 14 can be against the outer side of the rolling door and is used to apply a vertical pressure from the outside to the inside to the rolling door. The vertical adjustment device 14 and the vertical adjustment device 14 can be an electric telescopic cylinder, a hydraulic cylinder or a pneumatic cylinder. The vertical adjustment device 14 and the vertical adjustment device 14 are fixedly installed, one end of which is fixed and the other end is movable. The movable ends of the vertical adjustment device 14 and the vertical adjustment device 14 are retracted and do not contact the door leaf assembly 4 during the winding or unfolding process of the door leaf assembly 4. After the door leaf assembly 4 is fully unfolded, pressure is applied to the door leaf assembly 4 from the top and the outer side of the door leaf assembly 4, thereby improving the compactness of the door leaf assembly 4, which can not only improve the structural strength of the entire door leaf assembly 4, but also increase the deformation degree of the water-stop sealing strip, thereby improving the sealing between the door leaf units 7.

[0047] The present invention is based on the above structure, and its operation is as follows: 1. The door leaf assembly 4 is opened and closed by mechanical drive, and the water stop rubber strip 8 is compressed by the hydraulic system to seal the door; 2. A buzzer is provided, and the buzzer provides a sound alarm during the operation of the door leaf assembly 4; 3. An infrared sensor 2 is provided, and the opening range of the rolling door is monitored for foreign objects through the infrared sensor 2. If the infrared beam is broken, the infrared sensor 2 sends a signal, and the operation of the door leaf assembly 4 stops; 4. A liquid level sensor 1 is provided. When the flood water level in the surface space reaches the liquid level sensor 1, the liquid level sensor 1 sends a signal, and the door leaf assembly 4 is started to automatically close and seal the entrance and exit; 5. An uninterruptible power supply (UPS) is provided, which can provide a short-term independent power supply for the operation of the door leaf assembly 4 during a power outage. The automatic sealing flood-proof rolling shutter door provided by the present invention can be used as an overhead rolling shutter door in normal non-overflow operation. Once the control device senses water at a predetermined level, the present invention will automatically unfold and fix the opening. Alternatively, the door can be set to flood control mode by pressing a button. The door leaf assembly 4 is made of an aluminum rolling shutter door panel with a stainless steel frame and a flush threshold. At the same time, the present invention is equipped with a backup battery so that it can operate during power outages. The present invention is also provided with an infrared start / stop sensor to avoid closing when an object is in the way. The present invention can be applied to warehouses, entrance doors, storefronts, garage doors, parking lots, etc. The main functions of the present invention include: 1. On-site manual control, the operator realizes the opening and closing operations of the door leaf assembly 4 through the buttons of the local control cabinet; 2. On-site automatic control, automatic flood prevention is realized through the liquid level sensor 1 in conjunction with the microcontroller; 3.

[0048] From the above, it can be seen that the present invention provides an automatic sealing flood-proof rolling shutter door, which is arranged before the entrance and exit connecting the underground space and the surface space. In the present invention, the automatic sealing flood-proof rolling shutter door includes: a rolling shutter door that can be unfolded according to the flood situation of the surface space to achieve the closing of the entrance and exit and flood prevention; a door frame system that cooperates with the watertightness of the rolling shutter door, and the door frame system is fixed relative to the entrance and exit; in non-flooding conditions, the rolling shutter door can be stored to achieve the opening of the entrance and exit.
