[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0023] In existing technologies, such as Figure 1 As shown, the entrance and exit of the underground garage are marked with a ramp line 101, a ramp change line 102, and a drainage ditch 100. The drainage ditch 100 is located outside the ramp line 101 at the entrance and exit of the underground garage.
[0024] In addition to being installed at the vehicle entrance and exit of an underground parking garage, this invention can also be used in underground parking garages with multiple floors, with the structure described in this invention even on each floor.
[0025] like Figure 1 and Figure 2 As shown, this utility model discloses an automatically lifting flood-proof baffle structure, including a mounting slot 1. The mounting slot 1 is set on the ground between the ramp line 101 and the ramp change line 102 at the vehicle entrance and exit of the underground garage, preferably close to the ramp change line 102. The mounting slot 1 is parallel to the intercepting ditch 100 and penetrates the ground (e.g., Figure 2As shown in the diagram, a baffle 5 is installed in the mounting slot 1. The baffle 5 is driven to move up and down by a lifting mechanism. The control box 3 is located near the edge of the vehicle entrance / exit of the underground garage. A liquid level sensor 4 is installed between the mounting slot 1 and the drainage ditch 100. The liquid level sensor 4 is located close to the mounting slot 1, and its height can be set according to the site conditions. The liquid level sensor 4 is fixed to the wall or green edge stone embankment at the edge of the vehicle entrance / exit of the underground garage. The lifting mechanism includes a fixed slide rail 6, a drive motor 7, and a drive gear 12. One end of the fixed slide rail 6 is fixed at the lower end of the mounting slot 1 near the edge. The drive gear 12 is located on the output shaft of the drive motor 7. The fixed slide rail 6 has teeth that mesh with the drive gear 12. The teeth are located along the length of the fixed slide rail 6. The drive motor 7 is mounted on a fixed slide rail 6 with a rolling shaft 13 on one end facing the fixed slide rail 6. The rolling shaft 13 is adjacent to the drive gear 12. The fixed slide rail 6 is positioned between the rolling shaft 13 and the drive gear 12 to confine the drive motor 7 to the fixed slide rail 6. The edge of the fixed slide rail 6 opposite to the rolling shaft 13 is used as a guide. The baffle 5 is connected to the drive motor 7 so that the baffle 5 moves together with the drive motor 7 when it moves on the fixed slide rail 6. A waterproof gasket 2 is provided on the mounting slot 1 to prevent water from flowing into the mounting slot 1. Under normal conditions, the waterproof gasket 2 seals the mounting slot 1. When the baffle 5 rises, the waterproof gasket 2 is pushed open and comes into close contact with the surface of the baffle 5 to prevent water from flowing into the gap between the waterproof gasket 2 and the baffle 5, thus achieving the function of blocking water.
[0026] In this utility model, baffle guide supports 11 are provided at both ends of the baffle 5. The baffle guide supports 11 are used to prevent the baffle 5 from being washed away by water and to support the baffle 5. The baffle guide supports 11 can be the supports located on both sides used in the existing movable baffles. It is a vertical rod with guide grooves provided on the opposite side surfaces of the vertical rod. Of course, it can also be constructed by setting the wall edges or building columns on both sides of the entrance and exit of the underground garage. Figure 1 As shown, the baffle guide support 11 is composed of building columns located on both sides, and the edge of the baffle 5 abuts against the building columns.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the waterproof pad 2 is an integral part, which has a fixed end and a movable end. The fixed end is located on one side of the slope line 101, and the movable end is located on one side of the slope change line 102. The whole part covers the surface of the mounting slot 1. When the baffle 5 rises from the mounting slot 1, it pushes open the movable end of the waterproof pad 2 and makes the movable end fit against the surface of the baffle 5 to achieve the function of isolating water.
[0028] When the water level rises outside the vehicle entrance / exit of the underground garage, the liquid level sensor 4 is triggered and sends an electrical signal to the control box 3. The control box 3 then starts the drive motor 7. As the drive baffle 5 rises, the drive motor 7 moves together with the baffle 5. During the rise, the baffle 5 pushes up the movable end of the waterproof pad 2, which then adheres to the surface of the baffle 5. When the water level recedes, the liquid level sensor 4 is triggered again and sends an electrical signal to the control box 3. The control box 3 then drives the drive motor 7. As the drive baffle 5 descends, the drive motor 7 moves together with the baffle 5. After the baffle 5 descends into the mounting slot 1, the waterproof pad 2 covers the mounting slot 1 again.
[0029] like Figure 6 As shown, a groove 23 is provided at the lower end of the baffle 5, and a fixing mechanism is provided in the groove 23. The baffle 5 is connected and fixed to the drive motor 7 through the fixing mechanism in the groove 23. In this utility model, it is preferable that the baffle 5 is connected and fixed to the output shaft of the drive motor 7 through the fixing mechanism in the groove 23, that is, the groove 23 is placed on the output shaft of the drive motor 7.
[0030] like Figure 6 As shown, the fixing mechanism is an arc-shaped spring piece 14 set on the opposite sides of the groove 23 to restrict the output shaft of the drive motor 7 to rotate between the groove 23 and the arc-shaped spring piece 14. The arc-shaped spring piece 14 is made of stainless steel and is fixed in the groove 23 by snap-fit or screw connection.
[0031] like Figure 5 As shown, induction switches 16, which are electrically connected to the control box, are provided at the upper and lower ends of the fixed slide rail 6. When the drive motor 7 moves to the highest or lowest position, the induction switch 16 sends an electrical signal to the control box 3 to control the start and stop of the drive motor 7. Of course, the drive motor 7 can also be set as a servo motor to improve the movement accuracy.
[0032] like Figure 4 As shown, the control box 3 is equipped with a detachable control panel 10. The control panel 10 has control buttons to control the drive motor. The control panel 10 can be installed in the monitoring room or emergency center. The control panel 10 can have 5 control buttons, namely automatic, manual, stop, rise, and fall, to realize automatic control of the drive motor through the control box 3, liquid level sensor 4, and inductive switch 16. Alternatively, the drive motor 7 can be manually controlled by switching to manual mode and using the stop, rise, and fall control buttons. This is existing technology and will not be described in detail here.
[0033] This utility model also includes a manual emergency drive mechanism, such as... Figure 2 and Figure 3 As shown, the manual emergency drive mechanism includes a turntable 8 and a rocker arm 9, as... Figure 7 As shown, the output shaft of the drive motor 7 extends out of the drive gear 12, the center of the turntable 8 is connected to the output shaft of the drive motor 7, and the rocker arm 9 is eccentrically connected to the turntable 8 so that the turntable 8 can be rotated by the rocker arm 9 to manually raise the baffle 5.
[0034] like Figure 7 As shown, the turntable 8 is provided with an eccentrically positioned shaft 17, and the rocker arm 9 is provided with a sleeve 18. The sleeve 18 is fitted onto the shaft 17 to allow the rocker arm 9 to be detachable. Specifically, the turntable 8 has a protrusion 19 at the center of one end facing the output shaft of the drive motor 7. The protrusion 19 has a locking hole 20 that matches the output shaft. The protrusion 19 also has a through hole 21 that communicates with the locking hole 20. The output shaft of the drive motor 7 has a pin hole 22 that communicates with the through hole 21. The through hole 21 has a locking pin 15 that passes through the through hole 21 and the pin hole 22. Disassembly can be achieved by simply pulling out the locking pin 15.
[0035] This utility model is applicable to underground garage entrances and exits, equipment room entrances and exits, etc., where flood protection barriers are required.
[0036] In this utility model, the width of the mounting slot 1 is 200mm, and a groove 200mm wide and 50-100mm deep is left on each long side of the mounting slot 1 for installing the waterproof gasket 2. A liquid level sensor (4) is installed near the baffle 5 at a height of 150mm from the ground (this value can be adjusted according to the minimum water level designed for flood-prone areas) to monitor the outdoor water level.
[0037] Non-working status: such as Figure 2 As shown, the drive motor 7 is located at the bottom of the fixed slide rail 6, the baffle 5 is below the mounting slot 1, and the waterproof gasket 2 is in a closed state.
[0038] Working status: such as Figure 3 As shown, the drive motor 7 is at the top of the fixed slide rail 6, the baffle 5 extends out of the mounting slot 1 from the ground, and the waterproof pad 2 is pushed open and tightly attached to the baffle 5 to prevent external water from flowing into the basement through the mounting slot 1.
[0039] Non-working state to working state transition: When the control panel 10 is in automatic state and the liquid level sensor 4 senses the liquid level signal, or when the control panel 10 is in manual state and the up button is pressed, the control box 3 starts the drive motor 7 to rise along the fixed slide rail 6, which drives the baffle 5 to rise and push open the waterproof rubber pad 2 until the drive motor 7 is at the top or the stop button is pressed, at which point the drive motor 7 stops working.
[0040] Working state to non-working state transition: When the control panel 10 is in automatic state and the liquid level sensor 4 detects the disappearance of the liquid level signal, or when the control panel 10 is in manual state and the descent button is pressed, the control box 3 starts the drive motor 7 to descend along the fixed slide rail 6, driving the baffle 5 to descend until the drive motor 7 is at the bottom of the fixed slide rail 6 or the stop button is pressed, at which point the drive motor 7 stops working.
[0041] Manual switching in emergencies: Since the turntable 8 and the drive motor 7 are coaxially connected, in emergencies (such as power outages, signal failures, etc.), workers can carry the joystick 9 to the corresponding position in the basement, connect it to the turntable 8, and manually raise or lower the baffle 5 to the required position or height (clockwise up, counterclockwise down).
[0042] This utility model is installed in one go during the construction of the building body, hidden below the entrance and exit of the underground garage. It can be automatically or manually raised in the event of flooding and automatically or manually lowered when the flood recedes, which greatly saves the preparation work before the flood and also avoids flooding losses due to lack of preparation when a flood occurs.
