A flip-type flood control wall water blocking device for river water blocking treatment

Abstract

The present invention relates to a flip-type flood control wall water blocking device for river water blocking treatment. The flood control wall uses a hydraulic cylinder to cooperate with a rack and pinion drive 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 particularly large 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 in particular to a flip-type flood control wall water blocking device for river water blocking treatment. Background Art

[0002] Most urban underground spaces and civil air defense projects are equipped with flood control gates at the highest point of the entrance and a sufficient number of flood control sandbags are prepared to prevent heavy 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 control gates" are temporary facilities and are usually idle. They need to occupy space for storage, and transportation, installation, and use are extremely inconvenient, requiring a large amount of manpower and material resources. In the event of a sudden extremely large flood disaster, huge heavy losses will be caused due to reasons such as the transportation and equipment maintenance of the "flood control gates" being unable to block the water source in time. For example, 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 flood control is required during a flood, it is necessary to temporarily carry the columns and baffles, install the columns on sockets or studs, 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, a flip-type flood control wall water blocking device for river water blocking treatment is provided, including a box body, a door leaf, and a driving component. The characteristics are as follows: The box body is arranged in a pit below the ground. The door leaf and the driving component are located inside the box body. The door leaf includes a water blocking panel and a backwater panel. One end of the door leaf is fixedly connected to a bottom shaft, and a gear is fixedly sleeved at one end of the bottom shaft. A bottom plate is fixedly arranged in the pit. The driving component includes a hydraulic cylinder and a rack. The hydraulic cylinder is fixed to the bottom plate through a hydraulic cylinder support component. The hydraulic cylinder is electrically connected to a remote control system. The telescopic shaft of the hydraulic cylinder is fixedly connected to the rack that is slidably connected to the bottom plate. The rack is meshed with the gear. The driving component is used to drive the door leaf to rotate around the bottom shaft. During the flood season, the door leaf can be rotated to a vertical state to block floods. During the non-flood season, the door leaf can be rotated to a horizontal state and be parallel to the road surface to connect, 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 by 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 by 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 in 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 lifting 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 rather than being completely in the vertical state. Since the rotation angle of the door leaf after it is completely lifted 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 door leaf to rotate an angle of 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 door leaf to rotate an angle of 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 or equal to 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 using the above method of triggering the lifting 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 inspect each part of the door leaf by controlling the segmented lifting 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, a flexible filter screen or water retaining cloth is provided at one end of the back water panel away from the bottom shaft and at the top of the side wall of the box body away from the bottom shaft. The filter screen or water retaining cloth is equal in width to the box body in the front-back direction. When the door leaf lies down and is embedded in the road surface, the filter screen or water retaining cloth is folded in the box body. When the door leaf rotates to the vertical state and blocks the flood, the filter screen or water retaining cloth opens and completely covers the box body, so as to prevent sundries such as rainwater, mud, sand, and leaves from entering the box body and causing pollution or blockage.

[0009] Furthermore, two cavities, left and right, are arranged inside the gate leaf. Reinforcement devices are respectively arranged in the two cavities. 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 is inclined towards the ground. The ejection mechanism includes a compression cylinder and an airbag. The compression cylinder is connected to the airbag and used for inflating the airbag. The airbag is closely attached to the tail end of the steel nail and used for ejecting 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 start and 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 fully 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 through the winding roller motor and reset the steel nails, and finally the staff fills the steel nail holes on the ground.

[0010] Furthermore, a horizontal detector is arranged between the water retaining panel and the water-receiving panel. The horizontal detector is electrically connected to the remote control system and is used to detect the level of the gate leaf after the flood season ends and the gate leaf topples and embeds into the road surface, so as to reflect the fit degree between the gate leaf and the road surface, enabling the staff to know whether the section where the gate leaf is located affects the normal passage of pedestrians and vehicles. If the level is less than the set value, the staff can control the hydraulic cylinder through the remote control system to fine-tune the level of the gate leaf.

[0011] Furthermore, the thickness of the gate leaf gradually increases from top to bottom, and one side of the water retaining panel of the gate leaf is inclined. Since the pressure on the gate leaf gradually increases from top to bottom when the flood comes, and the amount of water in each flood is uncertain, and the liquid level height of the flood is also high and low when it impacts the flood control and prevention wall, the lower part of the flood control and prevention wall gate leaf often bears greater water pressure. Therefore, the thickness of the gate leaf gradually increases from top to bottom. Specifically, one side of the water retaining panel of the gate leaf is inclined, that is, the side surface of the entire gate leaf is approximately an isosceles right triangle, which is beneficial to enhancing the impact resistance of the entire gate leaf.

[0012] Furthermore, a maintenance water stop cover plate is arranged above the hydraulic cylinder.

[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, and conduct intelligent management and analysis of data on the platform. It can 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 is used in cooperation with a rack and pinion 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. During the non-flood season, the gate leaf can be rotated to a horizontal state and connected in parallel with the road surface, 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 construction 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 setting a first pressure sensor on the surface of the middle section of the water retaining panel, the flood control and prevention wall can judge whether the flood season is coming based on the pressure borne by the water retaining panel. Thus, when the flood season arrives, the hydraulic cylinder is automatically activated to drive the gate leaf to rotate to a vertical state for flood prevention. After the flood season ends, the hydraulic cylinder is activated again to drive the gate leaf to rotate to a horizontal state and connect in parallel with the road surface, without affecting the free passage of pedestrians and vehicles. By setting 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 setting 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 quickly inflate the airbag. The airbag ejects steel nails and shoots them into the ground. The steel nails and steel ropes firmly fix the gate leaf to enhance the stability of the gate leaf and prevent it from being washed down by the flood. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The advantages, features and methods to achieve the above - mentioned purpose of the present invention will be clear through the accompanying drawings and subsequent detailed descriptions.

[0024] Embodiment:

[0025] Combined with Figures 1-3 , a flip - type flood - control wall water - blocking device for river water - blocking treatment, comprising a box body 1, a door leaf 2 and a driving assembly, characterized in that: the box body 1 is arranged in a pit below the ground, the door leaf 2 and the driving assembly are located inside the box body 1, the door leaf 2 includes a water retaining panel 3 and a back water panel 4, one end of the door leaf 2 is fixedly connected to a bottom shaft 5, one end of the bottom shaft 5 is fixedly sleeved with a gear 6, a bottom plate 7 is fixedly arranged in the pit, the driving assembly includes a hydraulic cylinder 8 and a rack 9, the hydraulic cylinder 8 is fixed on the bottom plate through a hydraulic cylinder support assembly 10, the hydraulic cylinder 8 is electrically connected to a remote control system, the telescopic shaft of the hydraulic cylinder 8 is fixedly connected to the rack 9 sliding on the bottom plate 7, the rack 9 is meshed with the gear 6, and the driving assembly is used to drive the door leaf 2 to rotate around the bottom shaft 5; during the flood season, the door leaf 2 can be rotated to a vertical state to block floods, and during the non - flood season, the door leaf 2 can be rotated to a horizontal state and be parallel to and connected with the road surface without affecting the free passage of pedestrians and vehicles.

[0026] A first pressure sensor 11 is arranged 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 8, and 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 8; 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 8 controls the telescopic shaft to extend, so that the door leaf 2 rotates to a vertical state to block floods, and 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 8 controls the telescopic shaft to shorten, and the door leaf 2 rotates to a horizontal state and lies down and is embedded in the road surface, being in the same plane as the road surface and connected with the road surface, and can be used as a passage for the free passage of pedestrians and vehicles.

[0027] The first pressure sensor 11 triggers the lifting of the gate 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 8 controls the gate leaf 2 to rotate by a certain angle instead of being in a completely vertical state. Since the rotation angle of the gate leaf 2 after it is completely lifted is 90 degrees, when a flood comes, when the pressure value borne by the first pressure sensor 11 reaches the trigger value for the first time, the hydraulic cylinder 8 controls the gate leaf 2 to rotate by an angle of 90 / n degrees. As the flood level slowly rises, when the pressure value borne by the first pressure sensor 11 reaches the trigger value for the second time, the hydraulic cylinder 8 controls the gate leaf 2 to rotate by an angle of 2*90 / n degrees, and so on, until the gate leaf 2 rotates 90 degrees to the vertical state, where n is an integer greater than or equal to 3. Since the amount of flood water is different each time the flood season comes, it is not necessary for the gate leaf 2 to be in a vertical state every time. By using the above-mentioned segmented trigger method for the lifting of the gate leaf 2, not only can the driving force of the hydraulic cylinder 8 be saved and the wear of the telescopic shaft of the hydraulic cylinder be reduced, but also the staff can control the segmented lifting of the gate leaf 2 to facilitate the maintenance of each part of the gate leaf 2 by the staff.

[0028] A waterproof camera 12 is provided at one end of the water retaining panel 3 away from the bottom shaft 5. The waterproof camera 12 is electrically connected to a remote control system and a display screen, and the waterproof camera 12 can rotate at multiple angles. The waterproof camera 12 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.

[0029] Furthermore, a flexible filter screen or water retaining cloth 20 is provided at one end of the backwater panel 4 away from the bottom shaft 5 and at the top of the side wall of the box body 1 away from the bottom shaft 5. The filter screen or water retaining cloth 20 is equal in width to the box body 1 in the front-rear direction. When the gate leaf 2 lies down and is embedded in the road surface, the filter screen or water retaining cloth 20 is folded inside the box body 1. When the gate leaf 2 rotates to the vertical state and blocks the flood, the filter screen or water retaining cloth 20 opens and completely covers the box body 1, thereby preventing sundries such as rainwater, mud, sand, and leaves from entering the box body 1 and causing pollution or blockage.

[0030] Inside the gate leaf 2, two cavities 19, one on the left and one on the right, are provided. Reinforcement devices are respectively arranged in the two cavities 19 on the left and right. The reinforcement device includes steel nails 13, steel ropes 14, a winding mechanism and an ejection mechanism. The middle section of the steel nail 13 is fixedly connected to the steel rope 14. The tip of the steel nail 13 is inclined towards the ground. The ejection mechanism includes a compression cylinder 15 and an airbag 16. The compression cylinder 15 is connected to the airbag 16 and is used to inflate the airbag 16. The airbag 16 is closely attached to the tail end of the steel nail 13 and is used to eject the steel nail 13 into the ground. The winding mechanism includes a winding roller 17 and a motor. The steel rope 14 is wound around the winding roller 17 and the end of the steel rope 14 is fixed to the winding roller 17. A second pressure sensor 18 is arranged at the position of half the height of the water retaining panel 3 from the ground. 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 to quickly inflate the airbag 16. The airbag 16 ejects the steel nail 13, and the winding roller 17 automatically unwinds. When the steel nail 13 is shot into the ground for a certain distance, the steel rope 14 is completely released and straightened. The steel nail 13 and the steel rope 14 firmly fix the gate leaf 2, which is used to enhance the stability of the gate leaf 2 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 13, drive the winding roller 17 to wind up by the winding roller motor and reset the steel nails 13. Finally, the staff fills the steel nail holes on the ground.

[0031] A horizontal detector is arranged between the water retaining panel 3 and the backwater panel 4. The horizontal detector is electrically connected to the remote control system and is used to detect the levelness of the gate leaf 2 after the gate leaf 2 topples and embeds into the road surface at the end of the flood season, so as to reflect the degree of fit between the gate leaf 2 and the road surface, enabling the staff to know whether the section where the gate leaf 2 is located affects the normal passage of pedestrians and vehicles. If the levelness is less than the set value, the staff can control the hydraulic cylinder through the remote control system to fine-tune the levelness of the gate leaf 2.

[0032] The thickness of the gate leaf 2 gradually increases from top to bottom, and one side of the water retaining panel 3 of the gate leaf 2 is inclined. Since the pressure on the gate leaf 2 gradually increases from top to bottom when the flood comes, and the amount of water in each flood is uncertain, and the liquid level height of the flood is also high and low when it impacts the flood control and prevention wall, the lower part of the flood control and prevention wall gate leaf 2 often bears greater water pressure. Therefore, the thickness of the gate leaf 2 gradually increases from top to bottom. Specifically, one side of the water retaining panel 3 of the gate leaf 2 is inclined, that is, the side surface of the entire gate leaf 2 is approximately an isosceles right triangle, which is beneficial to enhancing the impact resistance of the entire gate leaf 2.

[0033] An overhaul water stop cover plate is provided above the hydraulic cylinder 8.

[0034] 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, conduct joint regulation across the entire basin, make the facility more intelligent, and boost the high-quality development of the city.

[0035] The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
