An adjustable interception device for a small urban emergency flood control wall

Abstract

The present invention relates to an adjustable interception device for a small urban emergency flood control wall. The flood control wall uses a hydraulic cylinder in cooperation with a support rod to drive the wall to complete lifting and lowering. After being laid down, it is completely flush with the road surface. The panel is provided with anti-slip materials, which does not affect the passage of vehicles and pedestrians, and the lifting and lowering of the flood control wall can be controlled by electric, manual, remote control, induction and remote methods, and the control is convenient and fast. It solves the technical problems that the traditional flood control wall needs to occupy space for storage, and is extremely inconvenient for transportation, installation and use. Once a sudden major flood disaster occurs, due to reasons such as transportation and equipment maintenance, the water source cannot be blocked in time, resulting in huge and heavy losses.

Description

Technical Field

[0001] The present invention relates to the fields of river ecological restoration and flood control on both sides of the river, and particularly relates to an adjustable interception device for a small urban emergency flood control wall. Background Art

[0002] Most urban underground spaces and civil air defense projects are equipped with flood prevention water gates at the highest point of the entrance and sufficient flood control sandbags are prepared to prevent too much and concentrated rainfall from exceeding the design capacity of the original drainage system, resulting in waterlogging in the underground parking lot entrance due to the accumulated water volume exceeding the drainage flow, causing man-made disasters.

[0003] However, most of the gates configured for the "flood prevention gates" are temporary facilities and are usually idle at ordinary times. They need to occupy space for storage, and transportation, installation and use are extremely inconvenient, requiring a large amount of manpower and material resources. And once a sudden major flood disaster occurs, due to reasons such as the transportation and equipment maintenance of the "flood prevention gates", the water source cannot be blocked in time, resulting in huge and heavy losses. Such as the mobile flood control wall disclosed in Patent CN201310286257.3, the assembled mobile flood control wall disclosed in Patent CN201510327493.4, and the combined flood control wall disclosed in Patent CN201610591409.4. When a flood occurs and flood control is required, it is necessary to temporarily carry the columns and baffles, install the columns on the sockets or stud nails, and install the baffles between the columns to form a flood control wall. The transportation process is time-consuming and laborious, and the installation and disassembly process is cumbersome. Summary of the Invention

[0004] In view of the above, to solve the above problems, an adjustable interception device for a small urban emergency flood control wall is provided, which includes a box body, a door leaf and two groups of driving components. It is characterized in that: the box body is arranged in a pit below the ground, the door leaf and the driving components are located inside the box body, the door leaf includes a water retaining panel and a backwater panel, one end of the door leaf is fixedly connected to a bottom shaft, the bottom shaft is rotationally connected to the side wall of the box body through a bottom shaft support assembly, the driving component includes a hydraulic cylinder and a support rod, the hydraulic cylinder is fixedly connected to the bottom plate of the box body through a support assembly, a hydraulic cylinder groove cover plate is arranged on the top of the hydraulic cylinder, the support rod includes a first section and a second section, the first section is fixedly connected to the telescopic shaft of the hydraulic cylinder, the other end of the first section is rotationally connected to the second section through a rotating seat, the other end of the second section is rotationally connected to an ear plate fixedly arranged in the middle of the backwater panel, a support rod guide rail is arranged on the bottom plate of the box body, the rotating seat can slide on the support rod guide rail, the hydraulic cylinder is electrically connected to a remote control system, and the driving component is used to drive the door leaf to rotate around the bottom shaft; during the flood season, the door leaf can rotate to a vertical state and be used to block floods, and during the non-flood season, the door leaf can rotate to a horizontal state and be connected to the hydraulic cylinder groove cover plate, without affecting the free passage of pedestrians and vehicles.

[0005] Further, a first pressure sensor is provided on the surface of the middle section of the water retaining panel. The first pressure sensor is electrically connected to the hydraulic cylinder. The first pressure sensor is used to detect the pressure borne by the water retaining panel so as to automatically control the telescopic movement of the hydraulic cylinder. When the first pressure sensor detects that the liquid pressure borne on the surface of the water retaining panel is always higher than the set value for a period of time, the hydraulic cylinder controls the telescopic shaft to extend, so that the door leaf rotates to the vertical state to block the flood. When the first pressure sensor detects that the liquid pressure borne on the surface of the water retaining panel is always lower than the set value within a period of time, the hydraulic cylinder controls the telescopic shaft to shorten, and the door leaf rotates to the horizontal state and lies down and is embedded in the road surface, being on the same plane as the road surface and connecting with the road surface, and can be used as a passage for pedestrians and vehicles to pass freely.

[0006] Further, the first pressure sensor triggers the raising of the door leaf in a segmented manner, that is, when the pressure value borne by the first pressure sensor reaches the trigger value, the hydraulic cylinder controls the door leaf to rotate a certain angle instead of being completely in the vertical state. Since the rotation angle of the door leaf after it is completely raised is 90 degrees, when a flood comes, when the pressure value borne by the first pressure sensor reaches the trigger value for the first time, the hydraulic cylinder controls the rotation angle of the door leaf to be 90 / n degrees. As the flood slowly rises, when the pressure value borne by the first pressure sensor reaches the trigger value for the second time, the hydraulic cylinder controls the rotation angle of the door leaf to be 2*90 / n degrees, and so on, until the door leaf rotates 90 degrees to the vertical state, where n is an integer greater than 3. Since the amount of flood water is different each time during the flood season, the door leaf does not need to be in the vertical state every time. By adopting the above-mentioned method of triggering the raising of the door leaf in a segmented manner, it can not only save the driving force of the hydraulic cylinder and reduce the wear of the telescopic shaft of the hydraulic cylinder, but also the staff can conveniently overhaul each part of the door leaf by controlling the segmented raising of the door leaf.

[0007] Further, a waterproof camera is provided at one end of the water retaining panel away from the bottom shaft. The waterproof camera is electrically connected to the remote control system and the display screen, and the waterproof camera can rotate at multiple angles. The waterproof camera is electrically connected to the remote control system and the display screen, and can be used to observe the flood situation, monitor and record in real time, and facilitate the staff to discover abnormalities.

[0008] Further, two cavities, one on the left and one on the right, are provided inside the gate leaf. Reinforcement devices are respectively arranged in the two cavities on the left and right. The reinforcement device includes steel nails, steel ropes, a winding mechanism and an ejection mechanism. The middle section of the steel nail is fixedly connected to the steel rope, and the tip of the steel nail inclines towards the ground. The ejection mechanism includes a compression cylinder and an airbag. The compression cylinder is connected to the airbag and used to inflate the airbag. The airbag is closely attached to the tail end of the steel nail and used to eject the steel nail into the ground. The winding mechanism includes a winding roller and a motor. The steel rope is wound on the winding roller and the end of the steel rope is fixed to the winding roller. A second pressure sensor is arranged at the position of half the height of the gate leaf's water retaining panel from the ground. The second pressure sensor is electrically connected to the switch of the compression cylinder. When the liquid level height of the flood rises to half the height of the gate leaf, due to the second pressure sensor being subjected to the flood pressure, each group of compression cylinders is automatically triggered to open to quickly inflate the airbag. The airbag ejects the steel nail, and the winding roller automatically unwinds. When the steel nail is shot into the ground for a certain distance and the steel rope is completely released and straightened, the steel nail and the steel rope firmly fix the gate leaf, which is used to enhance the stability of the gate leaf and prevent it from being washed down by the flood. When the flood season ends, the staff can use tools to pull out the steel nails, drive the winding roller to wind up by the winding roller motor to reset the steel nails, and finally the staff fills the steel nail holes on the ground.

[0009] Further, a flexible filter screen or water retaining cloth is provided at one end of the water-facing panel away from the bottom shaft and one end of the hydraulic cylinder groove cover plate close to the water-facing panel. The filter screen or water retaining cloth is equal to the width of the box body in the front-back direction. When the gate leaf topples and embeds into the road surface, the flexible filter screen or water retaining cloth folds inside the box body. When the gate leaf rotates to the vertical state and blocks the flood, the flexible filter screen or water retaining cloth opens and cooperates with the hydraulic cylinder groove cover plate to jointly cover the box body, thereby preventing sundries such as rainwater, mud, sand, and leaves from entering the box body and causing pollution or blockage.

[0010] Further, a liquid level sensor and a timer are arranged on the water retaining panel. Both the liquid level sensor and the timer are electrically connected to a data memory. The data in the data memory can be synchronously transmitted to a remote control system. During each flood season, the liquid level sensor and the timer can respectively obtain the highest liquid level of the flood and the duration of the flood season, and automatically store the data, which is convenient for the staff to regularly analyze the local flood season situation, so as to improve the flood control and prevention wall targeted.

[0011] Further, a bottom shaft water stop assembly is provided between the bottom shaft fixing assembly and the side wall of the box body.

[0012] Further, a rubber side water stop is arranged between the gate leaf and the two side retaining walls.

[0013] Furthermore, the remote control system includes a recording and monitoring module, an abnormal alarm module, a data analysis module, a display module, and a remote control module. The remote control system can monitor and record in real time, automatically alarm for abnormalities, analyze data through intelligent management on the platform, and conduct joint regulation across the entire basin, making the facility more intelligent and boosting the high-quality development of the city.

[0014] The beneficial effects of the present invention are as follows:

[0015] In the present invention, a hydraulic cylinder cooperates with a support rod to drive the gate leaf to rotate around the bottom shaft; during the flood season, the gate leaf can be rotated to a vertical state to block floods, and during the non-flood season, the gate leaf can be rotated to a horizontal state and connected to the hydraulic cylinder groove cover plate, without affecting the free passage of pedestrians and vehicles. This solves the technical problems that traditional flood control walls require space for storage, and are extremely inconvenient for transportation, installation, and use. Moreover, for new projects, only a small amount of basic structure needs to be added during design, and for the renovation of old projects, only a small amount of road surface needs to be excavated. The product is an integrated device, and operation tests are completed before leaving the factory. When the equipment arrives at the site, it only needs to be installed by a crane and can be put into operation after passing the commissioning.

[0016] By arranging a first pressure sensor on the lower side of the water retaining panel, the flood control and prevention wall can judge whether the flood season is coming according to the pressure borne by the water retaining panel, so as to automatically start the hydraulic cylinder and drive the gate leaf to rotate to a vertical state for flood control when the flood season comes, and after the flood season ends, start the hydraulic cylinder again and drive the gate leaf to rotate to a horizontal state and connect it parallel to the road surface, without affecting the free passage of pedestrians and vehicles; by arranging a waterproof camera that can rotate at multiple angles, it is used to observe the flood situation, monitor and record in real time, and facilitate the staff to discover abnormalities.

[0017] By arranging a gate leaf reinforcement device, when the liquid level of the flood rises to half of the height of the gate leaf, the second pressure sensor automatically triggers the compression cylinder to start quickly inflating the airbag. The airbag pops out the steel nails and shoots them into the ground. The steel nails and steel ropes firmly fix the gate leaf, which is used to enhance the stability of the gate leaf and prevent it from being washed down by the flood.

[0026] A first pressure sensor 11 is provided on the surface of the middle section of the water retaining panel 3. The first pressure sensor 11 is electrically connected to the hydraulic cylinder 6. The first pressure sensor 11 is used to detect the pressure borne by the water retaining panel 3 so as to automatically control the telescopic movement of the hydraulic cylinder 6. When the first pressure sensor 11 detects that the liquid pressure borne on the surface of the water retaining panel 3 is always higher than the set value for a period of time, the hydraulic cylinder 6 controls the telescopic shaft to extend, so that the door leaf 2 rotates to the vertical state to block the flood. When the first pressure sensor 11 detects that the liquid pressure borne on the surface of the water retaining panel 3 is always lower than the set value within a period of time, the hydraulic cylinder 6 controls the telescopic shaft to shorten, and the door leaf 2 rotates to the horizontal state and lies down and is embedded in the road surface, being in the same plane as the road surface and connected to the road surface, and can be used as a passage for pedestrians and vehicles to pass freely.

[0027] The first pressure sensor 11 triggers the lifting of the door leaf 2 in a segmented manner, that is, when the pressure value borne by the first pressure sensor 11 reaches the trigger value, the hydraulic cylinder 6 controls the door leaf 2 to rotate a certain angle instead of being completely in the vertical state.

Since the amount of flood water is different each time during the flood season, the door leaf 2 does not need to be in the vertical state every time. By using the above method of triggering the lifting of the door leaf 2 in a segmented manner, it can not only save the driving force of the hydraulic cylinder 6 and reduce the wear of the telescopic shaft of the hydraulic cylinder, but also the staff can conveniently inspect each part of the door leaf 2 by controlling the segmented lifting of the door leaf 2.

At the position of half the height of the water retaining panel 3 from the ground, a second pressure sensor 18 is provided. The second pressure sensor 18 is electrically connected to the switch of the compression cylinder 15. When the liquid level height of the flood rises to half the height of the gate leaf 2, due to the second pressure sensor 18 being subjected to the flood pressure, each group of compression cylinders 15 is automatically triggered to open and quickly inflate the airbag 16. The airbag 16 ejects the steel nail 13, and the winding roller 17 automatically unwinds.
