Description

Technical Field

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

[0002] Flood is a highly destructive natural disaster that can quickly inundate large areas, posing a direct threat to the lives of local residents. Especially floods caused by severe weather such as sudden heavy rain, which are different from predictable situations such as river flood discharges. Such floods form rapidly, have a short response time, but relatively low water volume. If not prevented in time, they will still cause floods to invade and affect human and even property safety. For example, in power plants, substations and other infrastructure in major power projects such as new energy power generation and power transmission equipment projects, if floods are not prevented in time, the infrastructure will be damaged by floods, and in severe cases, the entire power transmission system will be affected, causing significant impacts.

[0003] In recent years, the global climate anomaly has intensified, extreme rainstorm weather has occurred frequently, urban flood disasters have occurred frequently, typhoon hazards have increased day by day, and seawater backflow events have occurred occasionally in coastal cities. Especially for power facilities located in low-lying areas or near rivers and seas, the risks they bear are greater. To ensure safety, a more perfect flood control system needs to be established.

[0004] Among them, for each basic power facility, 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 foundation, for example, corresponding fences are set in the facility area. However, at the fence gates or other building entrances and exits, it is necessary to keep the access unobstructed during normal use. Therefore, it is not appropriate to set corresponding blocking measures. When floods come, water blocking operations need to be carried out.

[0005] Currently, many automatic flood control gates have emerged on the market. Such flood control gates can be installed flat at the corresponding positions. When floods come, the gate panels can automatically turn up to achieve rapid response and block floods. And during normal use, the gate panels are laid flat downward, which does not affect vehicle passage and can achieve good flood control effects.

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

[0007] Among them, since the rising, falling and flipping of the gate plate all rely on its rotating pair connection with 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) will be subjected 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, and 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 condition 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 gates are 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. In severe cases, it is even easy to get stuck, resulting in the gate plate being unable to flip up normally.

[0010] A rotating shaft hole structure is provided in the support structure, the rotating shaft structure penetrates the rotating shaft hole structure and forms a rotating fit, the rotating shaft hole structure is composed of a positioning circular hole portion and a gap circular hole portion, the positioning circular hole portion is smoothly connected to the inner wall of the gap circular hole portion, and the positioning circular hole portion is located at an obliquely upper position of the gap circular hole portion away from the movable side of the movable gate plate;

[0011] The diameter of the arc inner wall of the positioning circular hole portion is the same as the diameter of the rotational fitting surface of the rotating shaft structure, and the diameter of the arc inner wall of the clearance circular hole portion is greater than the diameter of the rotational fitting surface of the rotating shaft structure;

[0012] A plurality of groups of reinforcing support frames are fixedly installed inside the bottom frame, and supporting pads are fixedly installed at positions of the movable gate plates corresponding to the reinforcing support frames.

[0013] In a preferred embodiment, a sealing soft plate is arranged between the two ends of the movable gate plate and the wall structure, and a limited pulling structure is arranged between the movable gate plate and the bottom frame. The limited pulling structure is used to form a pulling force on the movable gate plate when the movable gate plate is flipped up, and an external sealing structure is commonly connected to the bottom frame and the movable side of the movable gate plate.

[0014] In a preferred embodiment, the rotating shaft structure includes a fixed shaft and a bearing. The fixed shaft is fixedly installed on the movable shutter, and the fixed shaft penetrates through the rotating shaft hole structure on the support structure. The bearing is installed on the fixed shaft, and the bearing is located in the rotating shaft hole. The rotating contact surface of the rotating shaft structure is the outer wall surface of the outer ring of the bearing.

[0015] In a preferred embodiment, an arc-shaped tail plate is arranged at the position of the movable shutter corresponding to the connection side. The outer arc surface of the arc-shaped tail plate is concentrically arranged with the rotating contact surface of the rotating shaft structure. An internal sealing structure is fixedly installed in the bottom frame, and an arc-shaped fitting surface adapted to the arc-shaped tail plate is arranged on the internal sealing structure. The arc surface of the arc-shaped fitting surface is concentrically arranged with the inner wall arc of the positioning round hole part.

[0016] In a preferred embodiment, a strengthening and restricting frame is fixedly installed outside the internal sealing structure. The strengthening and restricting frame is fixedly installed in the bottom frame. The strengthening and restricting frame wraps the area of the internal sealing structure except the arc-shaped fitting surface. A hollow cavity is arranged inside the internal sealing structure, and the hollow cavity is connected with a pressure pipe, and the pressure pipe is connected with an inflation and pressurization structure.

[0017] In a preferred embodiment, the floating body structure includes a fixed shell and a buffer shell. The fixed shell is fixedly installed on the movable shutter, and the buffer shell is connected with the fixed shell through an elastic connection part. The elastic connection part is a rubber cylinder structure, and the side wall of the elastic connection part is arranged in a corrugated shape.

[0018] In a preferred embodiment, multiple groups of floating body structures are arranged on the movable shutter. Spaces are left between the areas of the respective floating body structures corresponding to the strengthening support frames. The respective floating body structures are interconnected through a communicating air pipe. The inflation and pressurization structure is the floating body structure, and the pressure pipe is communicated with the inner cavity of the floating body structure.

[0019] In a preferred embodiment, positioning holes are arranged on the strengthening support frame, and positioning pin shafts are arranged on the movable shutter. After the movable shutter is turned down, the positioning pin shafts are inserted into the positioning holes.

When the positioning pin shaft is inserted into the positioning hole, the floating shaft presses the locking pin block downward under the action of gravity, so that the locking pin block extends out to form a snap fit with the inner convex step, and the bottom end of the floating shaft extends out of the positioning pin shaft and is fixedly connected with a floating ball.

[0021] In a preferred embodiment, a detection component is further provided on the movable shutter. The detection component includes a liquid level sensor and an audible and visual alarm. The audible and visual alarm is installed on the movable side of the movable shutter, and the liquid level sensor is installed on the inner side of the movable shutter.

[0022] The beneficial effects of the present invention are as follows: By providing a positioning circular hole part and a clearance circular hole part to cooperate with the rotating shaft structure, when the movable shutter is in the downward turning state, the movable shutter is supported by the strengthening support frame. At this time, the rotating shaft structure is located in the clearance circular hole part, and there is a clearance between the rotating contact surface of the rotating shaft structure and the inner wall of the clearance circular hole part. Even if a vehicle passes over the movable shutter and impacts or squeezes the movable shutter, the impact and extrusion force will not act on the support structure. Therefore, the stability and safety between the rotating shaft structure and the support structure can be maintained, and the two will not impact each other and cause wear or deformation. Furthermore, the stable use of the rotating support component can be ensured, thereby avoiding the phenomenon that the rotating structure is damaged due to being run over by a vehicle for a long time and cannot be turned up normally when facing floods, greatly improving the safety and stability of the device.

Detailed implementation manners

[0033] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0034] Refer to the attached drawings of the specification Figure 1, A hydrodynamic intelligent flood control gate, comprising a bottom frame 1 and a movable gate panel 2. One side of the movable gate panel 2 is the connection side (only relatively fixed in position and still capable of generating a flipping motion), and the other side is the movable side. The connection side of the movable gate panel 2 is rotationally matched with the bottom frame 1 through a rotational support assembly 3, enabling the movable gate panel 2 to flip up and down in the bottom frame 1. Among them, the bottom frame 1 is a groove-shaped structure and can accumulate water inside. One side of the bottom frame 1 corresponding to the movable side of the movable gate panel 2 is provided with a water inlet 11, and a grille structure is placed in the water inlet 11 for support. At the same time, a water outlet structure is provided inside the bottom frame 1, but the channel area of the water outlet structure is smaller than that of the reinforcement support frame 12. Specifically, when it rains normally, although the reinforcement support frame 12 can let water in, the amount of water entering is equivalent to the rainfall, and the water outlet structure can drain it in time. When external water accumulation or flood arrives, a large amount of water enters the bottom frame 1 from the reinforcement support frame 12 (in the direction towards the side where the flood comes), forming water accumulation in the bottom frame 1. And a floating structure 21 (such as a hollow integral floating box structure) is fixedly installed on the inner side (the bottom side when in the downward-flipped state) of the movable gate panel 2. The floating structure 21 provides buoyancy for the movable gate panel 2. Then, as the flood arrives, under the action of water, the movable gate panel 2 automatically flips up. And sealing soft plates 4 (rubber soft plates) are arranged between the two ends of the movable gate panel 2 and the wall structure, thus forming a barrier against the flood. And in the case of the gradually increasing flood, under the combined action of the lateral water pressure and buoyancy, the movable gate panel 2 continues to gradually flip until it flips to the vertical state. And a limit pulling structure 13 (such as a foldable pull rod structure and a steel cable structure, etc.) is arranged between the movable gate panel 2 and the bottom frame 1. The limit pulling structure 13 is used to form a pulling force on the movable gate panel 2 in the direction opposite to the direction of the water pressure action when the movable gate panel 2 flips up, so as to keep the movable gate panel 2 in the vertical state to effectively block the flood. At the same time, to maintain the seal of the rotating part, an external seal structure 14 (rubber plate structure) is jointly connected at the movable side of the bottom frame 1 and the movable gate panel 2 to achieve the seal of the rotating part.

[0035] It should be noted that the above is about the basic structure of the currently commonly used hydrodynamic flood control gate. Its specific detailed structure and installation method (such as the selection of the sealing soft plate 4 and the limit pulling structure 13, the installation of the bottom frame 1, etc.) are all prior arts. Therefore, this embodiment will not be elaborated too much. What this embodiment emphasizes is that in order to avoid damage to the rotational support assembly 3 caused by long-term vehicle rolling, the following technical solutions are also provided in this embodiment. Specifically, refer to the attached drawings of the specification. 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 connecting side on the movable gate plate 2. A rotating shaft hole structure is provided in the support structure 31. The rotating shaft structure 32 penetrates the rotating shaft hole structure and forms a rotating fit. The rotating shaft hole structure consists of a positioning circular hole portion 33 and a gap circular hole portion 34. The positioning circular hole portion 33 and the gap circular hole portion 34 are arranged to intersect, that is, the inner wall of the positioning circular hole portion 33 and the inner wall of the gap circular hole portion 34 are smoothly connected (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, so a trajectory of the intersection of the two circles is formed, and the figure is the positioning circular hole portion 33 and the gap circular hole portion 34 are combined to form a cross-sectional view of the hole), and an integrated hole structure is formed, 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 at an upper position of the center of the cross section of the gap circular hole portion 34 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 greater 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 flipped-down state, a plurality of 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 flipped-down 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 shaft structure 32 is located in the gap circular hole portion 34, and a gap is formed between the rotating fitting surface of the shaft structure 32 and the inner wall of the gap circular hole portion 34. Therefore, when there is no flood, the 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 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 normally flipped up when facing a flood, greatly improving the safety and stability of the device.

[0038] Based on the above solution, when a flood arrives, the movable gate 2 will still float and turn up under the influence of buoyancy, and 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 part 33, and the rotating contact surface of the rotating shaft structure 32 is in close contact with the positioning circular hole part 33. The lateral pressure of water will push the turned-up movable gate 2 backward, and coupled with the upward buoyancy of the movable gate 2, it can ensure that the rotating shaft structure 32 is firmly located in the positioning circular hole part 33, maintaining a stable fit. Furthermore, after the movable gate 2 turns up, it will not shake, ensuring the safety of flood control operations.

[0039] Furthermore, in the above solution, the rotating shaft structure 32 can adopt a simple shaft structure, and form a rotational fit by means of the fit between the shaft and the hole. At this time, the rotating fit surface of the rotating shaft structure 32 is the outer wall of the shaft structure. When rotating, relative friction is formed between the outer wall of this shaft structure and the positioning circular hole part 33. In order to reduce the rotational resistance, the rotating shaft structure 32 can also adopt the following solution. The rotating shaft structure 32 includes a fixed shaft 321 and a bearing 322. Refer to the attached Figure 6 to the specification. The fixed shaft 321 is fixedly installed on the movable gate 2. The fixed shaft 321 penetrates through the rotating shaft hole structure on the support structure 31. The bearing 322 is installed on the fixed shaft 321, and the bearing 322 is located in the rotating shaft hole. The rotating contact 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 2 turns up and rotates, the bearing 322 enters the positioning circular hole part 33 and is in close contact with the positioning circular hole part 33, reducing the rotational friction by means of the positioning circular hole part 33.

[0040] Based on the above implementation manner, although the external sealing structure 14 is used in the prior art to seal the connection side of the movable gate 2, the external sealing structure 14 is exposed outside, and will also be crushed by vehicles synchronously and be in direct contact with 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, having a certain safety hazard. Therefore, this embodiment also provides the following technical solution. Specifically, refer to the attached Figure 3 and Figure 5, an arc-shaped tail plate 24 is provided at the position corresponding to the connection side of the movable gate 2. The outer arc surface of the arc-shaped tail plate 24 is concentrically arranged with the rotation fitting surface of the rotating shaft structure 32. An internal 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. An arc-shaped fitting surface 51 adapted to the arc-shaped tail plate 24 is provided on the internal sealing structure 5. The arc surface of the arc-shaped fitting surface 51 is concentrically arranged with the inner wall of the arc of the positioning circular hole part 33. That is, when the rotating shaft structure 32 enters the positioning circular hole part 33, the arc-shaped tail plate 24 is also concentrically arranged with the arc-shaped fitting surface 51. Therefore, when the movable gate 2 is turned up, the arc-shaped tail plate 24 is closely attached to the arc-shaped fitting surface 51, thereby forming a tight seal for the connection side of the movable gate 2, improving the flood control sealing effect, reducing potential safety hazards. At the same time, when the movable gate 2 is in the down-turned state, since the rotating shaft structure 32 has entered the clearance circular hole part 34, the axis of the arc-shaped tail plate 24 has deviated from the axis of the positioning circular hole part 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 internal sealing structure 5 is in an uncompressed 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 improved. Especially when an accident occurs and the movable gate 2 suddenly flips, the internal sealing structure 5 can still ensure close attachment to 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 solution can still be used to cover and prevent dust at the arc-shaped fitting surface 51, avoid sundries from entering, and provide secondary sealing. Even if the external sealing structure 14 has cracks or damage, there is still the internal sealing structure 5 for effective sealing protection. An absorbent expansion structure 55 can also be provided on the arc-shaped fitting surface 51. The absorbent expansion structure 55 is embedded in the arc-shaped fitting surface 51. The absorbent expansion structure 55 can be selected to be made of strip bags wrapped with absorbent expansion particles (referring to materials such as sodium polyacrylate and polyurethane foam used in absorbent expansion bags). When encountering floods, it can expand to further improve the sealing effect.

[0042] Furthermore, if the flood period is long and the movable gate 2 blocks floods more frequently, the arc-shaped fitting surface 51 will still be squeezed by the arc-shaped tail plate 24. To further improve the sealing effect and avoid the internal sealing structure 5 being damaged by the extrusion of the arc-shaped tail plate 24 to form a fitting gap, the present embodiment also provides the following technical solution. Specifically, refer to the attached Figure 7, an external fixing and installation of the built-in sealing structure 5 is provided with a strengthening and restricting frame 52. The strengthening and restricting frame 52 is fixedly installed in the bottom frame 1. The strengthening and restricting frame 52 wraps and forms a restriction on the area of the built-in sealing structure 5 except for the arc-shaped fitting surface 51. A hollow cavity 53 is arranged inside the built-in sealing structure 5. The hollow cavity 53 is connected with a pressurizing pipe 54. The pressurizing pipe 54 is connected with an inflation and pressurization structure. Thus, when a flood occurs, air can be further inflated into the hollow cavity 53 through the pressurizing pipe 54, 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 there are the limiting and pulling structure 13 and the rotating support assembly 3 to support the movable gate plate 2 after it is turned up, there are still undercurrents in some areas of the flood (such as the water flow formed when a vehicle or a ship passes by outside, or the action of water waves near the river or the sea and the action of external strong winds on the water, etc.). The undercurrent will directly impact 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. Therefore, the present embodiment also provides the following technical solution. Specifically, refer to the attached drawings of the specification. Figure 8 , the floating body 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 with the fixed shell 211 through an elastic connecting part 213, and the three form a hollow box body. The elastic connecting part 213 is a rubber cylinder structure, and the side wall of the elastic connecting part 213 is arranged in a corrugated shape. Thus, the elastic connecting part 213 can have multi-directional elasticity. Especially when facing the undercurrent, the undercurrent impact rushes towards the buffer shell 212 and forms an elastic deformation buffer by means of the elastic connecting part 213, reducing the impact of the undercurrent on the movable gate plate 2 itself. Multiple groups of floating body structures 21 are arranged on the movable gate plate 2, and there is a space between the areas of each floating body structure 21 corresponding to the strengthening support frame 12, so as to facilitate the cooperation between the strengthening support frame 12 and the floating body structure 21. The fixed shells 211 of each floating body structure 21 are communicated with each other through a communicating 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 turned up, therefore, the inflation and pressurization structure connected to the above pressurizing pipe 54 can directly use the floating body structure 21, that is, the pressurizing pipe 54 is communicated with the inner cavity of the floating body structure 21, so as to make the air in the floating body structure 21 form compression by means of the flood pressure, thereby increasing the pressure in the hollow cavity 53 and improving the tightness of the contact between the arc-shaped fitting surface 51 and the arc-shaped tail plate 24. Moreover, when there is an undercurrent impact, the floating body structure 21 is compressed more, the pressure in the hollow cavity 53 is higher, and the matching effect between the arc-shaped tail plate 24 and the arc-shaped fitting surface 51 is better.

[0045] Based on the above embodiments, since the movable gate plate 2 is mainly supported by the reinforcing support frame 12 when there is no flood, in order to improve the supporting effect on the movable gate plate 2, referring to the appended drawings of the specification Figure 2 , positioning holes 121 can be provided on the reinforcing support frame 12, and positioning pin shafts 23 can be provided on the movable gate plate 2. After the flood recedes and the movable gate plate 2 is reset after being turned downwards, the positioning pin shafts 23 are gradually inserted into the positioning holes 121 for positioning (the positioning holes 121 can be provided with guiding groove structures to enable the positioning pin shafts 23 to accurately enter the positioning holes 121). Among them, multiple groups of the cooperation between the positioning pin shafts 23 and the positioning holes 121 can be set, and the positioning pin shafts 23 can adopt ordinary pin shaft structures.

[0046] However, the above positioning scheme cannot provide a downward pulling force for the movable gate plate 2, and thus, during use, upward movement may occur, intensifying the impact. For this reason, in this embodiment, the positioning pin shaft 23 is further improved. Specifically, referring to the appended drawings of the specification Figure 9 , a floating shaft 231 is slidably installed in the positioning pin shaft 23. A conical surface is provided at the bottom of the floating shaft 231. A locking pin block 232 is slidably installed in the side wall of the positioning pin shaft 23. An inner convex step 122 is provided in the positioning hole 121. A wedge 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 forms a snap fit with the inner convex step 122, thereby forming a downward fixing pulling force on the movable gate plate 2, making the docking of the movable gate plate 2 with the bottom frame 1 more stable and reducing the generation of vibration. The bottom end of the floating shaft 231 extends out of the positioning pin shaft 23 and is fixedly connected with a floating ball 233. When there is accumulated water in the bottom frame 1, the floating ball 233 floats first, so that the conical surface of the floating shaft 231 leaves the locking pin block 232, and when the movable gate plate 2 starts to turn upwards, the locking pin block 232 is squeezed back by the inner convex step 122, so as not to affect the extraction of the positioning pin shaft 23.

[0047] It should be noted that not all of the above positioning pin shafts 23 use the structure with the locking pin block 232. Most of the positioning pin shafts 23 can still use the common pin shaft structures. 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 provided to facilitate the staff to actively control the locking of the locking pin block 232.

[0048] In the above embodiment, for the convenience of monitoring and management, a detection component 6 is further provided on the movable gate 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 2, and the liquid level sensor is installed on the inner side of the movable gate 2. Thus, when a flood occurs and the movable gate 2 is lifted, the liquid level sensor is used to identify the flood and control the audible and visual alarm to give an alarm, so as to warn the vehicle not to move forward and warn the staff to handle it quickly. At the same time, the liquid level sensor can also monitor the water level at which the movable gate 2 blocks the flood (when the water level is too low, the movable gate 2 will gradually turn down, but it indicates that the flood has receded and there is no need to monitor the water level anymore), so as to facilitate real-time management. At the same time, the flipping of the above movable gate 2 can also be provided with an automatic flipping control device, such as a hydraulic cylinder, etc. In addition, based on the detection component 6, the flood control gate provided by the present invention can also be combined with the intelligent flood control monitoring system, that is, combined with the weather system, the monitoring system, etc. to monitor the environment in real time and take corresponding measures. When necessary, the movable gate 2 can be controlled to turn up in advance through the automatic flipping control device.

[0049] The above embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
