Description

Technical Field

[0001] The present invention relates to the technical field of flood control equipment, and more particularly to a hydrodynamic intelligent flood control gate. Background Art

[0002] Floods are extremely destructive natural disasters that can quickly inundate large areas, posing a direct threat to the lives and safety of local residents. Floods caused by severe weather such as sudden rainstorms are particularly rapid, requiring a shorter response time than more predictable events like river flooding. However, these floods have a relatively low volume, and if not prevented in a timely manner, they can still cause flooding and threaten human and even property safety. For example, failure to prevent floods in power plants, substations, and other infrastructure within major power projects, such as renewable energy power generation and transmission equipment projects, can lead to damage to these infrastructure, and in severe cases, even the entire power transmission system, causing significant impacts.

[0003] In recent years, global climate anomalies have intensified, with frequent extreme rainstorms, frequent urban floods, increasing typhoon hazards, and occasional seawater backflow into coastal cities. Power facilities located in low-lying areas or near rivers and seas are particularly at risk. To ensure safety, a more complete flood control system needs to be established.

[0004] Among them, for various basic power facilities, such as substations, various new energy power generation facilities (such as solar power plants, wind power generation facilities), etc., although such facilities have corresponding buildings as the basis, such as setting up corresponding walls in the facility area, it is necessary to maintain unobstructed access at the gate of the wall or other building entrances and exits during normal use. Therefore, it is not appropriate to set up corresponding blocking measures. When floods come, water blocking operations are required.

[0005] At present, there are many automatic flood gates on the market. Such flood gates can be installed flat in the corresponding position. When the flood comes, the gate plate can automatically flip up to achieve a quick response and block the flood. In normal use, the gate plate is laid flat downwards without affecting the passage of vehicles, and can play a good flood prevention effect.

[0006] However, for some power installation sites, heavy machinery often enters, such as maintenance vehicles, transport vehicles, etc., which is different from the parking lots in large communities and shopping malls where only small vehicles enter and exit. Heavy machinery is heavy in weight and will cause impact and extrusion on the flood control gate when passing through it. Although the compressive and impact resistance can be enhanced by strengthening the structural strength of the gate, it is limited by the overall installation environment. If the gate structure is too thick, the space and site required will be larger, and the installation and maintenance costs will be higher. Therefore, the actual design strength and structural thickness of the gate are also subject to certain limitations. Therefore, after long-term use, the gate will be damaged to a certain extent.

[0007] Among them, since the rising, falling and flipping of the gate plate all rely on its connection with the rotating pair of the ground structure, and when heavy machinery passes through the gate plate, it mainly produces a downward impact on the gate plate, especially the rotating pair (between the shaft and the shaft support structure), which will be subject to a downward impact. Over time, the lower structure of the rotating pair structure will produce corresponding deformation and wear, thereby affecting the rotation effect of the rotating pair. In severe cases, it is even easy to get stuck. Since floods such as heavy rains are sudden situations, the gate plate does not need to be flipped up before they occur, and the situation of the above-mentioned rotating pair is difficult to know. In the event of a sudden flood, if the rotating pair fails, the gate plate will not be able to flip up normally, which will seriously affect flood control operations, reduce flood control effects, and bring great risks. Summary of the Invention

[0008] The present invention provides a hydrodynamic intelligent flood gate to solve the problem that the existing flood gate is squeezed by heavy machinery for a long time, causing corresponding deformation and wear in the lower structure of the rotating pair structure, thereby affecting the rotation effect of the rotating pair.

[0014] In a preferred embodiment, the rotating shaft structure includes a fixed shaft and a bearing. The fixed shaft is fixedly mounted on the movable gate plate. The fixed shaft passes through the rotating shaft hole structure on the support structure. The bearing is mounted on the fixed shaft. The bearing is located in the rotating shaft hole.

[0016] In a preferred embodiment, a reinforced limiting frame is fixedly installed on the outside of the built-in sealing structure, and the reinforced limiting frame is fixedly installed on the bottom frame. The reinforced limiting frame wraps the area of the built-in sealing structure except the arc-shaped fitting surface. A hollow cavity is provided inside the built-in sealing structure, and the hollow cavity is connected to a pressurized tube, which is connected to the inflatable pressurized structure.

[0017] In a preferred embodiment, the floating structure includes a fixed shell and a buffer shell. The fixed shell is fixedly mounted on the movable gate plate. The buffer shell is connected to the fixed shell through an elastic connection part. The elastic connection part is a rubber tube structure. The side wall of the elastic connection part is configured to be corrugated.

[0018] In a preferred embodiment, multiple groups of floating structures are arranged on the movable gate plate, and space is left between the areas of each floating structure corresponding to the reinforced support frame.

DETAILED DESCRIPTION

[0033] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Refer to the instruction manual Figure 1A hydrodynamic intelligent flood control gate comprises a bottom frame 1 and a movable gate plate 2, one side of the movable gate plate 2 is a connection side (only the position is relatively fixed, and it can still produce a flipping movement), and the other side is a movable side. The connection side of the movable gate plate 2 is rotated with the bottom frame 1 through a rotating support component 3, so that the movable gate plate 2 can flip up and down in the bottom frame 1. The bottom frame 1 is a trough-shaped structure, and water can accumulate inside. A water inlet 11 is provided on one side of the bottom frame 1 corresponding to the movable side of the movable gate plate 2, and a grid is placed in the water inlet 11. The grating structure is used for support. At the same time, a water outlet structure is provided in the bottom frame 1, but the channel area of the water outlet structure is smaller than the channel area of the reinforcing support frame 12. Specifically, when it rains normally, although the reinforcing support frame 12 can enter water, the amount of water entering is equivalent to the amount of rainfall, and the water outlet structure can be discharged in time. When external water accumulation or flooding arrives, a large amount of water enters the reinforcing support frame 12 from the reinforcing support frame 12 into the bottom frame 1 (the direction is toward the side where the flood arrives), forming water accumulation in the bottom frame 1, and the inner side of the movable gate plate 2 (turned down) A floating structure 21 (e.g., a hollow, integrated pontoon structure) is fixedly mounted on the bottom side of the movable gate plate 2 when in the upright position. The floating structure 21 provides buoyancy for the movable gate plate 2. As the flood arrives, the movable gate plate 2 automatically flips up under the action of the water. Sealing soft panels 4 (rubber soft panels) are provided between the two ends of the movable gate plate 2 and the wall structure to form a barrier to the flood. As the flood gradually increases, the movable gate plate 2 continues to gradually flip over under the combined action of the lateral water pressure and the buoyancy until it flips over to the upright position. A limited pulling structure 13 (e.g., a foldable pull rod structure and a steel cable structure) is provided between the movable gate plate 2 and the bottom frame 1. The limited pulling structure 13 is used to generate a pulling force on the movable gate plate 2 in the opposite direction of the water pressure when the movable gate plate 2 flips up, thereby keeping the movable gate plate 2 in the upright position and effectively blocking the flood. At the same time, to maintain the sealing of the rotating part, an external sealing structure 14 (rubber plate structure) is connected to the movable side of the bottom frame 1 and the movable gate plate 2 to achieve sealing of the rotating part.

[0035] It should be noted that the above is the basic structure of the currently commonly used hydrodynamic flood gate. Its specific detailed structure and installation method (such as the selection of the sealing soft plate 4 and the limiting pulling structure 13, the installation of the bottom frame 1, etc.) are all existing technologies. Therefore, this embodiment will not be explained in detail. What this embodiment wants to emphasize is that in order to avoid long-term damage to the rotating support assembly 3 due to vehicle rolling, this embodiment also provides the following technical solutions. For details, please refer to the attached manual. Figures 2 to 9The rotating support assembly 3 includes a support structure 31 and a rotating shaft structure 32. The support structure 31 is fixedly installed in the bottom frame 1, and the rotating shaft structure 32 is fixedly installed at the position corresponding to the connection side on the movable gate plate 2. A rotating shaft hole structure is provided in the support structure 31. The rotating shaft structure 32 passes through the rotating shaft hole structure and forms a rotating fit. The rotating shaft hole structure is composed of a positioning circular hole portion 33 and a gap circular hole portion 34. The positioning circular hole portion 33 intersects with the gap circular hole portion 34, that is, the inner wall of the positioning circular hole portion 33 is smoothly connected with the inner wall of the gap circular hole portion 34 (the distance from the circular positioning circular hole portion 33 to the circular gap circular hole portion 34 is less than the sum of the radii of the two circles, thereby forming a trajectory of the intersection of the two circles. This figure is the positioning circular hole portion 33 and the gap circular hole portion 34 are combined (a cross-sectional view of the hole after the positioning circular hole portion 33 and the gap circular hole portion 34 are combined), and form an integrated hole structure, and the line connecting the respective centers of the shapes formed on the same cross-section of the positioning circular hole portion 33 and the gap circular hole portion 34 is an inclined structure, that is, the positioning circular hole portion 33 is located at an obliquely upper position of the gap circular hole portion 34, specifically, the center of the cross section of the positioning circular hole portion 33 is located above the center of the cross section of the gap circular hole portion 34, which is away from the movable side of the movable gate plate 2, and the diameter value of the arc inner wall of the positioning circular hole portion 33 is the same as the diameter value of the rotation fitting surface of the shaft structure 32 (that is, the outer surface of the actual rotating support structure), and the diameter value of the arc inner wall of the gap circular hole portion 34 is larger than the diameter value of the rotation fitting surface of the shaft structure 32.

[0036] In order to enhance the stability of the support when the movable gate plate 2 is in the downward flipped state, multiple sets of reinforcing support frames 12 are fixedly installed inside the bottom frame 1, and support pads 22 are fixedly installed at the positions of the movable gate plate 2 corresponding to the reinforcing support frames 12. When the movable gate plate 2 is in the downward flipped state, the floating structure 21 fits with the reinforcing support frames 12 to form a stable support for the movable gate plate 2.

[0037] It should be noted that when the movable gate plate 2 is in the downward flipped state, the movable gate plate 2 is supported by the reinforced support frame 12. At this time, the rotating shaft structure 32 is located in the gap circular hole portion 34, and a gap is formed between the rotating fitting surface of the rotating shaft structure 32 and the inner wall of the gap circular hole portion 34. Therefore, when there is no flood, the rotating shaft structure 32 does not form contact with the support structure 31. At this time, even if a vehicle passes over the movable gate plate 2 and impacts or squeezes the movable gate plate 2, the impact and squeezing force will not act on the support structure 31. Therefore, the stability and safety between the rotating shaft structure 32 and the support structure 31 can be maintained, and the two will not form mutual impact and cause wear or deformation, thereby ensuring the stable use of the rotating support assembly 3, thereby avoiding the phenomenon that the rotating structure is damaged due to long-term vehicle crushing and can no longer be turned up normally in the face of floods, greatly improving the safety and stability of the device.

[0038] Based on the above scheme, when a flood comes, the movable gate plate 2 will still float and flip up due to the influence of buoyancy, and will move away from the flood under the action of buoyancy and the lateral pressure of water. At this time, the rotating shaft structure 32 also moves into the positioning circular hole portion 33, and the rotating fitting surface of the rotating shaft structure 32 is tightly fitted with the positioning circular hole portion 33, and the lateral pressure of the water will push the flipped movable gate plate 2 backward. In addition, the movable gate plate 2 still has upward buoyancy, thereby ensuring that the rotating shaft structure 32 is firmly located in the positioning circular hole portion 33 and maintains a stable fit, so that the movable gate plate 2 will not shake after flipping up, thereby ensuring the safety of flood control operations.

[0039] Furthermore, in the above scheme, the rotating shaft structure 32 can adopt a simple shaft structure, and a rotational fit is formed by the cooperation between the shaft and the hole. At this time, the rotational fit surface of the rotating shaft structure 32 is the outer wall of the shaft structure, and when rotating, relative friction is formed between the outer wall of the shaft structure and the positioning circular hole portion 33. In order to reduce the rotational resistance, the rotating shaft structure 32 can also adopt the following scheme: the rotating shaft structure 32 includes a fixed shaft 321 and a bearing 322. Figure 6 The fixed shaft 321 is fixedly installed on the movable gate plate 2. The fixed shaft 321 passes through the rotating shaft hole structure on the support structure 31. The bearing 322 is installed on the fixed shaft 321. The bearing 322 is located in the rotating shaft hole. The rotating fitting surface of the rotating shaft structure 32 is actually the outer wall surface of the outer ring of the bearing 322. When the movable gate plate 2 is turned upside down, the bearing 322 enters the positioning circular hole portion 33 and fits tightly with the positioning circular hole portion 33, thereby reducing the rotational friction with the help of the positioning circular hole portion 33.

[0040] Based on the above embodiment, although the prior art adopts an external sealing structure 14 to seal the connection side of the movable gate plate 2, the external sealing structure 14 is exposed to the outside and will be simultaneously crushed by the vehicle and directly contact the external environment, which is easy to be damaged and aged, thereby affecting the sealing effect. In actual use, it is easy to cause flood leakage, which has certain safety hazards. For this reason, this embodiment also provides the following technical solutions. For details, refer to the attached manual. Figure 3 and Figure 5, the position of the movable gate plate 2 corresponding to the connection side is provided with an arc-shaped tail plate 24, and the outer arc surface of the arc-shaped tail plate 24 is concentrically arranged with the rotation fitting surface of the shaft structure 32. A built-in sealing structure 5 (such as a rubber structure) is fixedly installed at the position corresponding to the support structure 31 in the bottom frame 1. The built-in sealing structure 5 is provided with an arc-shaped fitting surface 51 adapted to the arc-shaped tail plate 24. The arc surface of the arc-shaped fitting surface 51 is concentrically arranged with the arc inner wall of the positioning circular hole portion 33, that is, when the rotating shaft structure 32 enters the positioning circular hole portion 33, the arc-shaped tail plate 24 is also concentrically arranged with the arc-shaped fitting surface 51. Therefore, when the movable gate plate 2 is flipped upward, the arc-shaped tail plate 24 is tightly fitted with the arc-shaped fitting surface 51, thereby forming a tight fit on the connection side of the movable gate plate 2. Sealing improves the flood-proof sealing effect and reduces safety hazards. At the same time, when the movable gate plate 2 is in the downward state, since the rotating shaft structure 32 has entered the gap circular hole portion 34, the axis of the arc-shaped tail plate 24 has deviated from the axis of the positioning circular hole portion 33. Therefore, the arc-shaped tail plate 24 will also deviate from the arc-shaped fitting surface 51, forming a gap with the arc-shaped fitting surface 51. That is to say, most of the time, the built-in sealing structure 5 is in a non-pressurized state and is located inside the bottom frame 1. Therefore, it can be effectively protected and the service life of the arc-shaped fitting surface 51 can be increased. Especially when the movable gate plate 2 suddenly flips over in an accident, the built-in sealing structure 5 can still ensure a close fit with the arc-shaped tail plate 24, thereby maintaining a good sealing effect.

[0041] It should be noted that the external sealing structure 14 mentioned in the above scheme can continue to be used to form a covering and dust-proof effect on the curved fitting surface 51, prevent the entry of debris, and provide secondary sealing. Even if the external sealing structure 14 is cracked or damaged, there is still an internal sealing structure 5 to provide effective sealing protection. A water-absorbing expansion structure 55 can also be provided on the curved fitting surface 51. The water-absorbing expansion structure 55 is embedded in the curved fitting surface 51. The water-absorbing expansion structure 55 can be made of water-absorbing expansion particles wrapped in strip bags (made of materials such as sodium polyacrylate and polyurethane foam used in water-absorbing expansion bags). When encountering floods, it can expand to further improve the sealing effect.

[0042] Furthermore, if the flood period is long and the number of times the movable gate plate 2 blocks the flood is large, the arc-shaped fitting surface 51 will still be squeezed by the arc-shaped tail plate 24. In order to further improve the sealing effect and prevent the built-in sealing structure 5 from being squeezed and damaged by the arc-shaped tail plate 24 to form a fitting gap, this embodiment also provides the following technical solutions. For details, refer to the attached manual. Figure 7A reinforced limiting frame 52 is fixedly installed on the outside of the built-in sealing structure 5, and the reinforced limiting frame 52 is fixedly installed in the bottom frame 1. The reinforced limiting frame 52 wraps the area of the built-in sealing structure 5 except the arc-shaped fitting surface 51 and forms a restriction. A hollow cavity 53 is provided inside the built-in sealing structure 5, and the hollow cavity 53 is connected to a pressure tube 54. The pressure tube 54 is connected to the inflatable pressurized structure, and then when a flood occurs, the pressure tube 54 can be used to further inflate the hollow cavity 53, so that the area of the built-in sealing structure 5 corresponding to the arc-shaped fitting surface 51 forms an outward expansion, which can further improve the fitting effect between the arc-shaped fitting surface 51 and the arc-shaped tail plate 24, and improve the sealing performance.

[0043] In the above embodiment, although the movable gate plate 2 is supported by the limited pulling structure 13 and the rotating support assembly 3 after it is flipped up, undercurrents still appear in some areas of flooding (for example, water currents formed when vehicles or ships pass by, or the effect of waves near rivers and seas, and the effect of strong winds on water, etc.). The undercurrents will cause a direct impact on the movable gate plate 2. If the impact is too large, it will affect the sealing stability of the built-in sealing structure 5 and the arc-shaped tail plate 24. For this reason, this embodiment also provides the following technical solutions. For details, please refer to the attached manual. Figure 8 The floating structure 21 includes a fixed shell 211 and a buffer shell 212. The fixed shell 211 is fixedly installed on the movable gate plate 2. The buffer shell 212 is connected to the fixed shell 211 through an elastic connection part 213, and the three form a hollow box. The elastic connection part 213 is a rubber tube structure. The side wall of the elastic connection part 213 is set to be corrugated, so that the elastic connection part 213 can have multi-directional elasticity, especially when facing an undercurrent, the undercurrent rushes towards the buffer shell 212, and with the help of the elastic connection part 213, an elastic deformation buffer is formed to reduce the impact of the undercurrent on the movable gate plate 2 itself. A plurality of floating structures 21 are arranged on the movable gate plate 2, and a space is left between the areas of each floating structure 21 corresponding to the reinforcement support frame 12 to facilitate the cooperation between the reinforcement support frame 12 and the floating structure 21, and the fixed shells 211 of each floating structure 21 are connected to each other through a connecting air pipe 214, thereby improving the overall anti-impact effect of the movable gate plate 2.

[0044] In addition, since the buffer shell 212 will be squeezed to a certain extent by the water pressure when the movable gate plate 2 is flipped up, the inflatable pressurized structure connected to the above-mentioned pressurized pipe 54 can directly use the floating structure 21, that is, the pressurized pipe 54 is connected to the inner cavity of the floating structure 21, so that the air in the floating structure 21 is compressed by means of flood pressure, thereby increasing the pressure in the hollow cavity 53 and improving the tightness of contact between the arc-shaped fitting surface 51 and the arc-shaped tail plate 24. Moreover, when there is an undercurrent impact, the floating structure 21 is compressed more, the pressure in the hollow cavity 53 is higher, and the arc-shaped tail plate 24 and the arc-shaped fitting surface 51 have a better coordination effect.

[0045] Based on the above embodiment, since the movable gate plate 2 is mainly supported by the strengthening support frame 12 when there is no flood, in order to improve the supporting effect of the movable gate plate 2, refer to the attached manual. Figure 2 A positioning hole 121 can be set on the reinforcing support frame 12, and a positioning pin 23 can be set on the movable gate plate 2. After the flood recedes and the movable gate plate 2 is flipped down and reset, the positioning pin 23 is gradually inserted into the positioning hole 121 for positioning (the positioning hole 121 can be provided with a guide groove structure so that the positioning pin 23 can accurately enter the positioning hole 121). Among them, the cooperation of the positioning pin 23 and the positioning hole 121 can be set in multiple groups, and the positioning pin 23 can adopt an ordinary pin structure.

[0046] However, the above positioning scheme cannot provide downward pulling force for the movable gate 2, and thus upward movement may occur during use, aggravating the impact. For this reason, the positioning pin 23 is also improved in this embodiment. For details, refer to the attached manual. Figure 9 , a floating shaft 231 is slidably installed in the positioning pin shaft 23, and the bottom of the floating shaft 231 is provided with an inverted cone surface, and a locking pin block 232 is slidably installed in the side wall of the positioning pin shaft 23, and an inner convex step 122 is provided in the positioning hole 121. A wedge-shaped surface is provided at one end of the locking pin block 232 corresponding to the floating shaft 231, and a round head structure is formed at the other end of the locking pin block 232. When the positioning pin shaft 23 is inserted into the positioning hole 121, the floating shaft 231 presses the locking pin block 232 downward under the action of gravity, so that the locking pin block 232 extends out and meets the inner convex step 122 forms a card engagement, thereby forming a fixed pulling force on the movable gate plate 2 downward, making the docking of the movable gate plate 2 and the bottom frame 1 more stable and reducing the generation of vibration, and the bottom end of the floating shaft 231 extends out of the positioning pin shaft 23 and is fixedly connected to the float 233. When there is water in the bottom frame 1, the float 233 floats up first, so that the inverted conical surface of the floating shaft 231 leaves the locking pin block 232, and when the movable gate plate 2 begins to flip up, the locking pin block 232 is squeezed back by the inner convex step 122, thereby not affecting the removal of the positioning pin shaft 23.

[0047] It should be noted that not all of the above positioning pin shafts 23 use a structure with a locking pin block 232. Most of the positioning pin shafts 23 still use the commonly used pin shaft structure. As for the floating shaft 231, its top can extend to the outside of the movable gate plate 2, and a pull rod structure can be set to facilitate the staff to actively control the lock of the locking pin block 232.

[0048] In the above embodiment, in order to facilitate monitoring and management, a detection component 6 is also provided on the movable gate plate 2. The detection component 6 includes an audible and visual alarm and a liquid level sensor. The audible and visual alarm is installed on the movable side of the movable gate plate 2, and the liquid level sensor is installed on the inner side of the movable gate plate 2. When a flood occurs, when the movable gate plate 2 is lifted, the flood is identified with the help of the liquid level sensor, and the audible and visual alarm is controlled to sound an alarm to warn vehicles not to move forward and to warn staff to deal with it quickly. At the same time, the liquid level sensor can also monitor the water level of the movable gate plate 2 to block the flood (when the water level is too low, the movable gate plate 2 will gradually flip down, but it means that the flood has receded and there is no need to monitor the water level) to facilitate real-time management. At the same time, the flipping of the above-mentioned movable gate plate 2 can also be provided with an automatic flipping control device, such as a hydraulic cylinder. In addition, based on the detection component 6, the flood control gate provided by the present invention can also be combined with an intelligent flood control monitoring system, that is, combined with the weather system, monitoring system, etc. to monitor the environment in real time and make corresponding measures. If necessary, the movable gate plate 2 can be controlled to flip up in advance through the automatic flipping control device.

[0049] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
