A high-sealing flip-type flood-proof baffle structure

Abstract

This invention discloses a high-sealing, flip-type flood-proof baffle structure, comprising a base plate installed inside the ground, with two walls symmetrically arranged on both sides of the top surface of the base plate, and a flip-type baffle positioned between the two walls. This invention utilizes the impact of accumulated water to cause the flip-type baffle to rotate synchronously with the sealing element via a G-shaped groove during the flipping process. The U-shaped part of the sealing element moves on the surface of the decorative panel, while always maintaining contact with the decorative panel. The U-shaped part expands and deforms under compression, achieving a waterproof seal between the flip-type baffle and the decorative panel throughout the flipping process. When the G-shaped groove is attached to the two sides of the flip-type baffle, the arc-shaped part at the bottom of the sealing element is wound around the surface of the insert rod. The insert rod, in conjunction with the bottom surface of the placement groove, compresses the arc-shaped part, ensuring a tight seal between the bottom of the two sides of the flip-type baffle and the base frame. When the flip-type baffle is not in operation, there are no other folding connecting parts between the two sides and the walls, minimizing the risk of accidental damage to the sealing element.

Description

Technical Field

[0001] This invention belongs to the field of floodproof baffle sealing technology, and specifically relates to a high-sealing flip-type floodproof baffle structure. Background Technology

[0002] Flip-type flood barriers are widely used at the entrances of underground garages, civil defense works, subways, and underground overpasses. During the flip-up opening process, both sides of the flood barrier need to maintain a seal with the installation wall at all times. Existing products generally use flexible rubber sheets or waterproof cloth to seal the sides with the installation wall. During the flipping process, the flexible rubber sheets or waterproof cloth are folded and deformed to keep the sides sealed. Because there are two flexible rubber sheets or waterproof cloths on the sides with a size not less than the water blocking height, the flood barrier is still folded on the sides when not in use. This is not only unsightly, but also easily damaged.

[0003] Therefore, it is necessary to invent a highly sealing flip-type flood-proof baffle structure to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a highly sealing, flip-type flood-proof baffle structure to solve the issues raised in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-sealing flip-type flood-proof baffle structure, comprising a base plate installed inside the ground, two walls symmetrically arranged on both sides of the top surface of the base plate, a flip plate arranged between the two walls, and both sides of the flip plate being tightly fitted with decorative panels on the inner sidewalls of the two walls using a fitting structure, and a base frame correspondingly fitted and installed on the top surface of the base plate between the two walls, with a placement groove corresponding to the flip plate at the center of the base frame, and both bottom sides of the flip plate being rotatably engaged with the two walls using insert rods, and when the flip plate is rotated using the insert rods, the front side of the flip plate is connected to the base frame using a connecting structure, and when the connecting structure is in a straight line, an acute angle structure is formed between the flip plate and the base frame.

[0006] Furthermore, the fitting structure includes a G-shaped groove and a sealing element correspondingly inserted into the inner side of the G-shaped groove. The top of the G-shaped groove is attached to the protrusions on the top of both sides of the flip plate. The sealing element includes a square part and a U-shaped part. A groove is provided in the center of the square part. The square part deforms through the groove. The sealing element is inserted into the inner side of the G-shaped groove by utilizing the deformed square part. The square part and the U-shaped part are integrated, and the U-shaped part is installed on the side of the square part.

[0007] Furthermore, the two side strips of the U-shaped part deform under the corresponding compression of the square part and the decorative panel. When the flip plate uses the G-groove to drive the sealing part to rotate synchronously between the two walls, the two deformed side strips of the U-shaped part are always in contact with the inner side wall of the decorative panel. The bottom end of the sealing part is connected to an arc-shaped part, which is wrapped around the surface of the insertion rod, and the concave surface of the arc-shaped part is in close contact with the surface of the insertion rod.

[0008] Furthermore, the bottom surface of the placement slot of the base frame is provided with an inner groove, the length and width of the flip plate are both greater than the length and width of the inner groove, and multiple strips are arranged side by side at equal intervals at the center of the bottom surface of the inner groove. The strips penetrate the base frame and the bottom surface of the base plate, and the base plate is connected to the external drainage system through the strips.

[0009] Furthermore, the connecting structure includes a first rotating plate and a second rotating plate, and the thickness of both the first rotating plate and the second rotating plate is less than the depth of the inner groove. The top of the first rotating plate is hinged to the front side of the flip plate using a connector, and the bottom of the second rotating plate is hinged to the inner groove using a connector, and the height of the connector is less than the depth of the inner groove. The bottom of the first rotating plate is rotatably connected to the top of the second rotating plate using a rotating rod. A damping ring is sleeved on the surface of the rotating rod, and the two ends of the damping ring are respectively attached to the sides of the first rotating plate and the second rotating plate.

[0010] Furthermore, the bottom of the second rotating plate is provided with a pushing structure that corresponds to and cooperates with multiple slots. The pushing structure includes multiple pressure strips, which correspond to and cooperate with multiple slots one by one. Both sides of the pressure strips are provided with rubber sheets that correspond to and fit against the two inner sidewalls of the slots.

[0011] Furthermore, the top surfaces of the multiple pressure strips are connected to crossbars by support rods, and the multiple pressure strips are integrated by the crossbars. The inner side of the base plate is provided with vertical grooves that penetrate multiple grooves, and corresponding limiting rods are placed and connected inside the vertical grooves. The limiting rods pass through multiple pressure strips in sequence, and the multiple pressure strips are rotatably engaged with the base plate by the limiting rods.

[0012] Furthermore, a screw rod passes through the center of the second rotating plate, and the screw rod is connected to the second rotating plate by a nut. A connecting plate is sleeved on the surface of the screw rod, and the bottom end of the connecting plate is rotatably sleeved on the surface of the crossbar.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. This invention utilizes the impact of accumulated water to cause the flipping plate to rotate synchronously with the sealing element via the G-groove during the flipping process. The U-shaped part of the sealing element moves on the surface of the decorative panel, while always being in contact with the decorative panel. The U-shaped part expands and deforms during compression, achieving a waterproof seal between the flipping plate and the decorative panel throughout the flipping process. When the G-groove is attached to the two sides of the flipping plate, the arc-shaped part at the bottom of the sealing element is wrapped around the surface of the insert rod. The insert rod and the bottom surface of the placement groove are used to compress the arc-shaped part. The deformed arc-shaped part ensures a seal between the bottom of the two sides of the flipping plate and the base frame. When the flipping plate is not in operation, there are no other folding connecting parts between the two sides and the wall, and the sealing element of the structure is not easily damaged.

[0015] 2. In this invention, the impact of accumulated water causes the flip-up plate to rotate between two walls using the insert rod. As the flip-up plate pulls the top of the first rotating plate upward, the first rotating plate, while rotating upward, pulls the top of the second rotating plate upward using the rotating rod. At this time, the second rotating plate rotates on the top of the base frame using the connecting piece. At this time, the first and second rotating plates gradually deform from the folded state. When the first and second rotating plates rotate in cooperation with the rotating rod, the damping ring also provides a blocking and limiting effect on the rotation of the first and second rotating plates as it rotates on the surface of the rotating rod. The damping ring prevents the flip-up plate from flipping arbitrarily on the top of the base frame. At the same time, the sliding friction between the U-shaped piece and the decorative panel also prevents the flip-up plate from flipping rapidly. The combination of the damping ring and the U-shaped piece reduces the collision damage between the flip-up plate and the base frame during the flipping process.

[0016] 3. When the pushing structure moves upward in this invention, the pushing structure causes multiple pressure strips to move upward synchronously. At this time, the pressure strips are separated from the groove. At this time, the water accumulated at the top of the base frame can be discharged into the external drainage system through the groove, avoiding the accumulation of water at the top of the base frame. When the impact of the water causes the flip plate to rotate, the G-groove on the side of the flip plate and the seal prevent water from passing through the flip plate. No additional power source is required, and the reliability is high. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides a highly sealing, flip-type flood-proof baffle structure, such as... Figure 1 As shown, the system includes a base plate 1 installed inside the ground. Two walls 2 are symmetrically arranged on both sides of the top surface of the base plate 1. A flip plate 3 is arranged between the two walls 2. Both sides of the flip plate 3 are tightly attached to the decorative panels 4 on the inner sidewalls of the two walls 2 using a fitting structure. A base frame 5 is installed between the two walls 2 and is correspondingly attached to the top surface of the base plate 1. A placement groove 6 corresponding to the flip plate 3 is provided at the center of the base frame 5. The bottom sides of the flip plate 3 are rotatably engaged with the two walls 2 using insert rods 7. When the flip plate 3 is rotated using the insert rods 7, the front side of the flip plate 3 is connected to the base frame 5 using a connecting structure. When the connecting structure is in a straight line, an acute angle structure is formed between the flip plate 3 and the base frame 5. When the flip plate 3 is placed inside the placement slot 6 inside the base frame 5, the top surface of the flip plate 3 is flush with the top surface of the base frame 5, making it easy for cars to pass through the base frame 5. When there is water accumulation outside, the flip plate 3 can be pulled up by the buoyancy of the water or manually. At this time, the impact force of the water on the flip plate 3 causes the flip plate 3 to rotate between the two walls 2 using the insertion rod 7. During the rotation, the flip plate 3 gradually pulls the connecting structure from the folded state to a straight state. At this time, the flip plate 3 and the base frame 5 form an acute angle structure, which makes it easy for the flip plate 3 to cooperate with the bonding structure to block water accumulation, so that the bonding structure is always waterproof and sealed with the decorative panel 4 during the flipping process.

[0025] exist Figure 2 and Figure 3 In this design, the fitting structure includes a G-shaped groove 8 and a sealing element 9 correspondingly inserted into the inner side of the G-shaped groove 8. The top of the G-shaped groove 8 is attached to the protrusions on the top of both sides of the flip plate 3. The sealing element 9 includes a square part 10 and a U-shaped part 11. The square part 10 has a groove at its center. The square part 10 deforms through the groove, and the sealing element 9 is inserted into the inner side of the G-shaped groove 8 by utilizing the deformed square part 10. The square part 10 and the U-shaped part 11 are integrated, and the U-shaped part 11 is installed on the side of the square part 10. First, the sealing element 9 is inserted into the G-shaped groove 8, and then the top of the G-shaped groove 8 is attached to the protrusions on the top of both sides of the flip plate 3. At this time, the G-shaped groove 8 is attached to both sides of the flip plate 3. Both sides of the flip plate 3 and the two decorative plates 4 limit the sealing element 9. At this time, the sealing element 9 deforms between the flip plate 3 and the decorative plates 4, and the deformed U-shaped part 11 is tightly attached to the surface of the decorative plate 4. The impact of the accumulated water causes the flip plate 3 to rotate synchronously with the seal 9 by using the G-groove 8 during the flipping process. At this time, the U-shaped part 11 of the seal 9 moves on the surface of the decorative panel 4, and the U-shaped part 11 of the seal 9 is always in contact with the decorative panel 4 and compresses the U-shaped part 11, causing the U-shaped part 11 to open and deform, thereby achieving waterproof sealing between the flip plate 3 and the decorative panel 4 during the flipping process.

[0026] exist Figures 1 to 3 In this process, the two side strips of the U-shaped component 11 deform under the corresponding compression of the square component 10 and the decorative panel 4. When the flip plate 3 uses the G-groove 8 to drive the sealing component 9 to rotate synchronously between the two walls 2, the two deformed side strips of the U-shaped component 11 are always in contact with the inner wall of the decorative panel 4. The bottom end of the sealing component 9 is connected to an arc-shaped component 12, which is wrapped around the surface of the insert rod 7, and the concave surface of the arc-shaped component 12 is in close contact with the surface of the insert rod 7. When the G-groove 8 is attached to the two sides of the flip plate 3, the arc-shaped component 12 at the bottom end of the sealing component 9 is wrapped around the surface of the insert rod 7. The insert rod 7 and the bottom surface of the placement groove 6 are used to compress the arc-shaped component 12. The deformed arc-shaped component 12 ensures the sealing between the bottom of the two sides of the flip plate 3 and the base frame 5.

[0027] exist Figure 1 and Figure 4In this design, an inner groove 13 is provided on the bottom surface of the placement slot 6 of the base frame 5. The length and width of the flip plate 3 are both greater than the length and width of the inner groove 13. Multiple slots 14 are arranged equidistantly at the center of the bottom surface of the inner groove 13. The slots 14 penetrate the bottom surfaces of the base frame 5 and the base plate 1, and the base plate 1 is connected to the external drainage system via the slots 14. When the flip plate 3 cooperates with the fitting structure to block external water accumulation, the fitting structure prevents water from entering the garage through the gap between the flip plate 3 and the wall 2. Since the plane where the top surface of the slots 14 is located is lower than the plane where the placement slot 6 and the inner groove 13 are located, the water accumulation at the top of the base frame 5 will be discharged into the external drainage system through the multiple slots 14. This improves the flood prevention effect of the garage and also allows for timely drainage of accumulated water, preventing water from accumulating at the garage entrance.

[0028] exist Figure 1 and Figure 2 In the above, the connecting structure includes a first rotating plate 15 and a second rotating plate 16, and the thickness of the first rotating plate 15 and the second rotating plate 16 is less than the depth of the inner groove 13. The top end of the first rotating plate 15 is hinged to the front side of the flip plate 3 by a connector, and the bottom end of the second rotating plate 16 is hinged to the inner groove 13 by a connector, and the height of the connector is lower than the depth of the inner groove 13. The bottom end of the first rotating plate 15 is rotatably connected to the top end of the second rotating plate 16 by a rotating rod 17. A damping ring 18 is sleeved on the surface of the rotating rod 17, and the two ends of the damping ring 18 are respectively attached to the sides of the first rotating plate 15 and the second rotating plate 16. The impact of the accumulated water causes the flip plate 3 to rotate between the two walls 2 using the insert rod 7. When the flip plate 3 pulls the top of the first rotating plate 15 upward, the first rotating plate 15 pulls the top of the second rotating plate 16 upward using the rotating rod 17 during the upward rotation. At this time, the second rotating plate 16 rotates on the top of the base frame 5 using the connecting piece. At this time, the first rotating plate 15 and the second rotating plate 16 gradually begin to deform from the folded state. When the first rotating plate 15 and the second rotating plate 16 rotate in cooperation with the rotating rod 17, the damping ring 18 also provides a blocking limit to the rotation of the first rotating plate 15 and the second rotating plate 16 during the rotation of the rotating rod 17. The damping ring 18 is used to prevent the flip plate 3 from flipping arbitrarily on the top of the base frame 5. At the same time, the sliding friction limit between the U-shaped piece 11 and the decorative plate 4 also prevents the flip plate 3 from flipping quickly. The combination of the damping ring 18 and the U-shaped piece 11 reduces the collision damage between the flip plate 3 and the base frame 5 during the flipping process.

[0029] exist Figure 1 , Figure 2 and Figure 4In the middle, the bottom of the second rotating plate 16 is provided with a pushing structure that corresponds to and cooperates with multiple grooves 14. The pushing structure includes multiple pressure strips 19, which correspond to and cooperate with multiple grooves 14 one by one. Moreover, the two sides of the pressure strips 19 are provided with rubber sheets that correspond to and fit against the two inner sidewalls of the grooves 14. When the pushing structure moves upward, it causes multiple pressure strips 19 to move upward simultaneously. At this time, the pressure strips 19 separate from the grooves 14, and the water accumulated on the top of the base frame 5 can be discharged into the external drainage system through the grooves 14, preventing water from accumulating on the top of the base frame 5. After the water recedes, the impact force of the water on the flip plate 3 decreases. The weight of the flip plate 3 itself and the impact force of the water work together to gradually reduce the acute angle between the flip plate 3 and the base frame 5. When the rotating flip plate 3 pushes the pushing structure downward, the pushing structure causes multiple pressure strips 19 to engage with multiple grooves 14 one by one. The rubber sheets on both sides of the pressure strips 19 scrape the two inner walls of the grooves 14 to prevent stones and debris in the water from clogging the grooves 14 and ensure the normal discharge of water.

[0030] exist Figure 1 , Figure 2 and Figure 4 In this structure, the top surfaces of multiple pressure strips 19 are connected to crossbars 20 via support rods, and the multiple pressure strips 19 are integrated with the crossbars 20. A vertical groove 21 penetrating multiple slots 14 is provided on the inner side of the base plate 1, and a limiting rod 22 is correspondingly placed and connected inside the vertical groove 21. The limiting rod 22 sequentially penetrates multiple pressure strips 19, and the multiple pressure strips 19 are rotatably engaged with the base plate 1 via the limiting rod 22. A screw 23 penetrates the center of the second rotating plate 16, and the screw 23 is connected to the second rotating plate 16 via a nut 24. A connecting plate 25 is sleeved on the surface of the screw 23, and the bottom end of the connecting plate 25 is rotatably sleeved on the surface of the crossbar 20. The second rotating plate 16 rotates under the pull of the bottom of the first rotating plate 15. During the rotation, the second rotating plate 16 drives the screw 23 to rotate synchronously. The screw 23 is limited by the nut 24. The screw 23 pulls the crossbar 20 to move by the connecting plate 25. When the crossbar 20 moves the multiple pressure strips 19 upward, one end of the pressure strip 19 is limited to the inside of the groove 14 by the cooperation of the limiting rod 22 and the vertical groove 21. At this time, when the crossbar 20 pulls the pressure strip 19 upward, the multiple pressure strips 19 rotate inside the vertical groove 21 by the limiting rod 22. The pressure strips 19 also cause the limiting rod 22 to move upward inside the vertical groove 21 until the first rotating plate 15 and the second rotating plate 16 are in a straight line state and the multiple pressure strips 19 are separated from the groove 14. The tilting plate 3 inclined to the bottom plate 1 prevents water from entering the garage.

[0031] Working principle of this invention:

[0032] Refer to the attached diagram in the instruction manual. Figures 1 to 4When water accumulates outside, the flip plate 3 is pulled up. The impact of the water on the flip plate 3 causes it to rotate between the two walls 2 using the insert rod 7. When the flip plate 3 pulls the top of the first rotating plate 15 upward, the first rotating plate 15, during its upward rotation, uses the rotating rod 17 to pull the top of the second rotating plate 16 upward. At this time, the second rotating plate 16 rotates on the top of the base frame 5 using the connecting piece. At this time, the first rotating plate 15 and the second rotating plate 16 gradually begin to deform from the folded state. When the first rotating plate 15 and the second rotating plate 16 rotate in cooperation with the rotating rod 17, the damping ring 18 also dampens the first rotating plate 16 as it rotates on the surface of the rotating rod 17. The rotation of plate 15 and the second rotating plate 16 provides a blocking limit. The damping ring 18 prevents the flipping plate 3 from flipping arbitrarily on the top of the base frame 5. At the same time, the sliding friction limit between the U-shaped piece 11 and the decorative plate 4 also prevents the flipping plate 3 from flipping rapidly. The combination of the damping ring 18 and the U-shaped piece 11 reduces the collision damage between the flipping plate 3 and the base frame 5 during the flipping process, until the flipping plate 3 gradually pulls the connecting structure from the folded state to the straight state during the rotation. At this time, the flipping plate 3 and the base plate 1 form an acute angle structure. The flipping plate 3 and the bonding structure cooperate to block water accumulation, so that the bonding structure and the decorative plate 4 are always waterproof and sealed during the flipping process.

[0033] During the flipping process, the G-groove 8 drives the sealing element 9 to rotate synchronously. At this time, the U-shaped part 11 of the sealing element 9 moves on the surface of the decorative panel 4, and the U-shaped part 11 of the sealing element 9 is always in contact with the decorative panel 4 and compressed, causing the U-shaped part 11 to open and deform, thereby achieving waterproof sealing between the flipping plate 3 and the decorative panel 4 during the flipping process. When the G-groove 8 is attached to the two sides of the flipping plate 3, the arc-shaped part 12 at the bottom of the sealing element 9 is wrapped around the surface of the insert rod 7. The insert rod 7 and the bottom surface of the placement groove 6 are used to squeeze the arc-shaped part 12. The deformed arc-shaped part 12 ensures the sealing between the bottom of the two sides of the flipping plate 3 and the base frame 5.

[0034] The second rotating plate 16 rotates under the pull of the bottom of the first rotating plate 15. During the rotation, the second rotating plate 16 drives the screw 23 to rotate synchronously. The screw 23 is limited by the nut 24. The screw 23 pulls the crossbar 20 to move by the connecting plate 25. When the crossbar 20 moves the multiple pressure strips 19 upward, one end of the pressure strip 19 is limited to the inside of the groove 14 by the cooperation of the limiting rod 22 and the vertical groove 21. At this time, when the crossbar 20 pulls the pressure strip 19 upward, the multiple pressure strips 19 rotate inside the vertical groove 21 by the limiting rod 22. The pressure strips 19 also cause the limiting rod 22 to move upward inside the vertical groove 21 until the first rotating plate 15 and the second rotating plate 16 are in a straight line state and the multiple pressure strips 19 are separated from the groove 14. The flip plate 3 is used to prevent water from entering the garage.

[0035] The pushing structure causes multiple pressure strips 19 to move upwards simultaneously. At this time, the pressure strips 19 separate from the grooves 14, and the water accumulated on the top of the base frame 5 can be discharged into the external drainage system through the grooves 14, preventing water from accumulating on the top of the base frame 5. After the water recedes, the impact force of the water on the flip plate 3 decreases. The weight of the flip plate 3 itself and the impact force of the water work together to gradually reduce the acute angle between the flip plate 3 and the base frame 5. When the rotating flip plate 3 pushes the pushing structure downwards, the pushing structure causes multiple pressure strips 19 to be locked in place with multiple grooves 14 one by one. The rubber sheets on both sides of the pressure strips 19 scrape the two inner walls of the grooves 14 to prevent stones and debris in the water from clogging the grooves 14 and ensure the normal discharge of water.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
