Description

Technical Field

[0001] The present invention relates to the technical field of subway flood control supporting facilities, and particularly relates to a flood control device for subway station entrances and exits. Background Art

[0002] Currently, due to the global warming and the heat island effect and rain island effect caused by the rapid development of cities, the sudden, local and high-intensity extreme rainstorm weather in big cities shows an obvious increasing trend. In the face of rainstorms, subways are frequently flooded and damaged, and the vulnerability and hidden dangers of the construction are exposed. Due to the characteristics of underground stations themselves, in extreme rainstorm weather, water accumulation in a certain section of the subway and flood backflow into the station, resulting in the flooding of the subway tunnel are likely to occur. At present, the flood control materials at each entrance and exit of the rail transit industry generally include flood control (water blocking) boards, water blocking bags, sandbags, anti-slip mats and other flood control materials, which will affect the passage after playing the role of blocking water. For example, after the flood control (water blocking) board is raised, it will affect the evacuation of personnel or the entry and exit of materials from the subway station, and it is inconvenient to carry the step ladders on both sides of the flood control (water blocking) board. If inclined plates are added on both sides of the flood control (water blocking) board, due to the high height of the flood control (water blocking) board, the slope of the inclined plate is large, and it is slippery during the flood season, which makes people prone to fall.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Embodiment 1

[0023] As Figures 1 to 7 shown, a flood control device for the entrance and exit of a subway station provided by the present invention includes a pit 1. The pit 1 is arranged at the station entrance 10. Guide rails 2 are fixedly connected to the inner walls on both sides of the pit 1. A sliding seat 21 is slidably connected to the guide rails 2. A first electric push rod 22 is installed at one end of the guide rails 2. A driving motor 23 is fixedly connected to one side of the sliding seat 21. A support plate 3 is rotatably connected to the other side of the sliding seat 21. The driving motor 23 is coaxially and fixedly connected to the rotating shaft of the support plate 3. A waterproof strip 11 is fixedly connected to the pit 1. After the support plate 3 is in the vertical state, the first electric push rod 22 pushes the sliding seat 21 to move outward from the station entrance 10. The edge of the vertical support plate 3 presses against the waterproof strip 11 to form a seal, and the water blocking effect is good;

[0024] Support plates 4 are respectively rotatably connected to both sides of the support plate 3. An installation groove 40 is arranged on one side of the support plate 4. A folding ladder is arranged in the installation groove 40. An interlocking device is arranged on the support plate 4. The interlocking device is used to transform the folding ladder from a flat state to a stepped state after the support plate 4 rotates.

[0025] A clamping groove 12 is arranged on one side of the pit 1. On the one hand, it provides a space for horizontal movement when the support plate 3 is horizontal. On the other hand, on one side of the pit 1, it provides support and limitation for the upper support plate 4.

[0026] The present invention pushes the sliding seat 21 to move through the first electric push rod 22, makes the support plate 3 vertical through the driving motor 23 at a suitable position. The vertical support plate 3 moves outward from the station entrance 10 through the sliding seat 21. The edge of the vertical support plate 3 presses against the waterproof strip 11 to form a seal, and the water blocking effect is good; Subsequently, through the rotation of the support plate 4, slopes are formed on both sides of the support plate 3, and at the same time of forming the slopes, in cooperation with the interlocking device, steps are automatically formed on the support plate 4, which is convenient for emergency personnel to climb over the vertical support plate 3 and plays a role in safely and quickly evacuating personnel.

[0027] Embodiment 2

[0028] As Figures 1 to 7As shown in the figure, the support plate 3 is provided with a through groove 31. A second electric push rod 32 is hingedly connected within the through groove 31. The second electric push rods 32 controlling the two side support plates 4 are arranged in a staggered manner. The bottom of the support plate 4 is slidably connected to a slider 33. The telescopic end of the second electric push rod 32 is hingedly connected to the slider 33. The interlocking device includes a push-pull rod 41. An avoidance groove 42 is provided on one side of the support plate 4 close to the slider 33. The push-pull rod 41 slides within the support plate 4 and one end enters the avoidance groove 42 and is fixedly connected to the slider 33. One side of the installation groove 40 is fixedly connected to an interlocking box 43. The other end of the push-pull rod 41 extends into the interlocking box 43 and is provided with a tooth groove. A gear 44 is rotatably connected within the interlocking box 43. A first bevel gear 45 is fixedly connected to one side of the gear 44. A driving rod 46 is rotatably connected within the installation groove 40. A second bevel gear 47 is fixedly connected to the driving rod 46. The first bevel gear 45 meshes with the second bevel gear 47;

[0029] A plurality of sliding rods 48 are slidably connected within the installation groove 40. A ladder plate 49 is hingedly connected between two adjacent sliding rods 48. One end of the ladder plate 49 is hingedly connected to the sliding rod 48, and the other end of the ladder plate 49 is hingedly connected to the ladder plate 49 on the adjacent sliding rod 48. When all the sliding rods 48 approach each other, the two adjacent ladder plates 49 gradually turn into a vertical state. When all the sliding rods 48 move away from each other, the two adjacent ladder plates 49 gradually turn to the same plane. Each sliding rod 48 is provided with a threaded sleeve 481. The driving rod 46 passes through the threaded sleeve 481 and is threadedly connected thereto, and the pitch of the threaded sleeve 481 in the axial direction of the driving rod 46 decreases in sequence.

[0030] In Embodiment 2, when the second electric push rod 32 extends and cooperates with the sliding of the slider 33, the support plate 4 rotates to form slopes on both sides of the support plate 3. When the slider 33 slides, the push-pull rod 41 of the interlocking device slides along with the slider 33. The sliding of the push-pull rod 41 causes the driving rod 46 to rotate through the gear 44, the first bevel gear 45, and the second bevel gear 47. The driving rod 46 does not require additional power drive, which is convenient for forming the required functions in a narrow space. When the driving rod 46 rotates, due to the pitch of the threaded sleeve 481 decreasing in sequence, the sliding distances of the successive sliding rods 48 increase in sequence, thereby forming a stepped shape, which is convenient for personnel to quickly climb over in an emergency.

[0031] Embodiment 3

[0032] As Figures 1 to 7 shown, on the basis of Embodiment 2, the ladder plate 49 is provided with an avoidance hole 482, and the sliding rod 48 is threadedly connected to a locking bolt 483. When the ladder plate 49 is in a stepped state, an inner hexagon wrench is inserted through the avoidance hole 482 to loosen the locking bolt 483. After the locking bolt 483 is loosened, the sliding rod 48 can axially move relative to the threaded sleeve 481, that is, the sliding rods 48 slide in sequence so that the multiple ladder plates 49 form a plane, which is convenient for the passage of wheelchairs or carts for emergency supplies; after passing through, after the sliding rods 48 are pushed back and reset to a stepped state, the sliding rods 48 and the threaded sleeves 481 are re-locked, and the device can be reset to its normal state.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
