A small urban flood control wall with self-emergency sensing function

Abstract

The present invention relates to a small urban flood control wall with a self-emergency sensing function. The flood control wall uses a rolling door motor to drive the door leaf to complete the lifting movement. During the non-flood season, it can be completely hidden in the retaining wall groove, without affecting the passage of vehicles and pedestrians, and the lifting of the flood control wall can be controlled by electric, manual, remote control, induction and remote methods, which 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 to a small urban flood control wall with a self-emergency sensing function. 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 the rain volume from being too large and concentrated, exceeding the design capacity of the original drainage system, resulting in the water accumulation at the entrance of the underground parking lot exceeding the drainage flow and causing waterlogging and man-made disasters.

[0003] However, most of the gates configured for the "flood control gates" are temporary facilities, which are usually idle at ordinary times, need to occupy space for storage, and are extremely inconvenient for transportation, installation and use, requiring a large amount of manpower and material resources. In the event of a sudden extremely large flood disaster, due to reasons such as the transportation and equipment maintenance of the "flood control gates", the water source cannot be blocked in time, resulting in huge and heavy losses. 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 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 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 processes are cumbersome. Summary of the Invention

[0004] In view of the above, to solve the above problems, a small urban flood control wall with a self-emergency sensing function is provided, which includes a retaining wall, a door leaf, a door frame and a driving component. The characteristics are as follows: the retaining wall is arranged in a pit below the ground surface of the flood control section, a groove is opened inside the retaining wall, the door leaf is slidably arranged in the groove, and the door leaf includes a water retaining panel and a back water panel; the door frame is erected on the flood control section, the door frame includes a cross beam and a vertical beam, the driving component includes a rolling door motor and an integrated pumping station control box, the rolling door motor is arranged in the middle of the cross beam, the winding wire of the rolling door motor is fixedly connected to the top of both sides of the door leaf, the rolling door motor is electrically connected to a remote control system, and the rolling door motor is used to drive the door leaf to lift in the groove and the door frame; during the flood season, the door leaf can rise to the flood control section to block the flood, and during the non-flood season, the door leaf can descend into the groove, and the top is parallel and fitted with the road surface, without affecting the free passage of pedestrians and vehicles.

[0005] Furthermore, a first pressure sensor is arranged at the top of the door leaf, the first pressure sensor is electrically connected to the rolling door motor, and the first pressure sensor is used to detect the pressure borne by the top of the door leaf so as to automatically control the winding and unwinding of the winding wire of the rolling door motor.

[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 rolling door motor controls the door leaf to lift a certain height instead of lifting completely. Set the height after the door leaf is completely lifted as H. When a flood comes, when the pressure value borne by the first pressure sensor reaches the trigger value for the first time, the rolling door motor controls the door leaf to lift a height of H / n. As the flood level slowly rises, when the pressure value borne by the first pressure sensor reaches the trigger value for the second time, the rolling door motor controls the door leaf to lift a height of 2H / n, and so on, until the door leaf is completely lifted and the height reaches H, where n is an integer greater than or equal to 4. Since the amount of flood water is different each time during the flood season, it is not necessary for the door leaf to be completely lifted each time. By adopting the above-mentioned segmented triggering method for the door leaf to lift, it can not only save the power of the rolling door motor, but also reduce the wear generated when the door leaf slides in the groove. Moreover, the staff can control the segmented lifting of the door leaf to facilitate the maintenance of each part of the door leaf by the staff.

[0007] Further, a waterproof camera is provided at the top of the water retaining panel. 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, left and right, are provided inside the door leaf. Reinforcing devices are respectively provided in the two cavities, left and right. The reinforcing 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 is used to inflate the airbag. The airbag is closely attached to the tail end of the steel nail and is 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 provided at the position of half the height of the water retaining panel of the door leaf 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 door leaf, due to the second pressure sensor being affected by the flood pressure, each group of compression cylinders is automatically triggered to start inflating the airbag quickly. 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 door leaf, which is used to enhance the stability of the door 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 and reset the steel nails, and finally the staff fills the steel nail holes on the ground.

[0009] Furthermore, a liquid level sensor and a timer are provided on the water retaining panel. Both the liquid level sensor and the timer are electrically connected to a data memory, and 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 water level of the flood and the duration of the flood season, and automatically store the data, thereby facilitating the staff to regularly analyze the local flood season situation and thus improve the flood control and prevention wall targeted.

[0010] Furthermore, a perpendicularity detector is provided between the water retaining panel and the backwater panel. The perpendicularity detector is electrically connected to the remote control system. Since the flood control and prevention wall may tilt after being impacted by the flood, the perpendicularity detector can be used to detect whether the door leaf is perpendicular to the ground before the door leaf enters the retaining wall groove at the end of the flood season, thereby reflecting the fit degree between the door leaf and the retaining wall groove, enabling the staff to know whether the door leaf can completely enter the groove, and further knowing whether the section where the door leaf is located affects the normal passage of pedestrians and vehicles. If the door leaf has a certain inclination angle with the ground and cannot be completely hidden in the retaining wall groove, the staff can timely learn about the abnormal situation of the door leaf and thus carry out corresponding repairs.

[0011] Furthermore, a guide rail is provided in the vertical beam, and a pulley is provided on the side wall of the door leaf. The pulley is slidably matched with the guide rail.

[0012] Furthermore, a maintenance water stop cover plate is provided on the top of the rolling door motor.

[0013] Furthermore, the remote control system includes a record monitoring module, an abnormal alarm module, a data analysis module, a display module, and a remote control module.

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

[0015] The present invention drives the door leaf to lift in and out of the groove of the retaining wall through a rolling door motor. During the flood season, the door leaf can rise to the flood control section to block the flood. During the non-flood season, the door leaf can descend into the groove, and the top is parallel and fitted with the road surface, without affecting the free passage of pedestrians and vehicles, solving the technical problems that the traditional flood control wall needs to occupy space for storage, and transportation, installation and use are extremely inconvenient.

[0016] By setting a first pressure sensor at the top of the gate leaf, the flood control and prevention wall can determine whether the flood season is coming according to the pressure borne by the top of the gate leaf. Thus, when the flood season comes, the rolling door motor is automatically started to wind up and drive the gate leaf to rise to the flood control section for flood prevention. After the flood season ends, the rolling door motor is started again to unwind and drive the gate leaf to descend into the groove and fit parallel to 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 start and quickly inflate 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] Combined with Figures 1-4, A small urban flood control wall with a self - emergency sensing function, comprising a retaining wall 1, a door leaf 2, a door - type frame 3 and a driving assembly. It is characterized in that: the retaining wall is arranged in a pit below the ground of the flood - control section. A groove 4 is opened inside the retaining wall, and the door leaf 2 is slidably arranged in the groove 4. The door leaf 2 comprises a water - retaining panel 5 and a back - water panel 6; the door - type frame 3 is erected on the flood - control section. The door - type frame 3 comprises a cross - beam and a vertical beam. The driving assembly comprises a rolling door motor 7 and an integrated pump station control box. The rolling door motor 7 is arranged in the middle of the cross - beam. The winding wire of the rolling door motor 7 is fixedly connected to the top of both sides of the door leaf 2. The rolling door motor 7 is electrically connected to a remote control system. The rolling door motor 7 is used to drive the door leaf 2 to lift in the groove 4 and the door - type frame 3. During the flood season, the door leaf 2 can rise to the flood - control section to block floods. During the non - flood season, the door leaf 2 can descend into the groove 4, and its top is parallel and fitted with the road surface, without affecting the free passage of pedestrians and vehicles.

[0027] A first pressure sensor 8 is arranged at the top of the door leaf 2. The first pressure sensor 8 is electrically connected to the rolling door motor 7. The first pressure sensor 8 is used to detect the pressure borne by the top of the door leaf 2 so as to automatically control the winding and unwinding of the winding wire of the rolling door motor 7.

[0028] The first pressure sensor 8 triggers the rising of the door leaf 2 in a segmented manner, that is, when the pressure value borne by the first pressure sensor 8 reaches the trigger value, the rolling door motor 7 controls the door leaf 2 to rise by a certain height rather than completely rise. Set the height after the door leaf 2 completely rises as H. When a flood comes, the pressure value borne by the first pressure sensor 8 reaches the trigger value for the first time, and the rolling door motor 7 controls the door leaf 2 to rise by a height of H / n. As the flood slowly rises, the pressure value borne by the first pressure sensor 8 reaches the trigger value for the second time, and the rolling door motor 7 controls the door leaf 2 to rise by a height of 2H / n, and so on, until the door leaf 2 completely rises and the height reaches H, where n is an integer greater than or equal to 4; since the amount of flood water is different each time the flood season comes, the door leaf 2 does not need to rise completely each time. By adopting the above - mentioned segmented - trigger rising method of the door leaf 2, it can not only save the power of the rolling door motor 7, but also reduce the wear generated when the door leaf 2 slides in the groove 4. Moreover, the staff can control the segmented rising of the door leaf 2 to facilitate the staff to repair each part of the door leaf 2.

[0029] A waterproof camera 9 is arranged at the top of the water - retaining panel 5. The waterproof camera 9 is electrically connected to the remote control system and a display screen. The waterproof camera 9 can rotate at multiple angles; the waterproof camera 9 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.

[0030] Inside the gate leaf 2, two cavities 10, one on the left and one on the right, are provided. Reinforcement devices are respectively arranged in the two cavities 10 on the left and right. The reinforcement device includes steel nails 11, steel ropes 12, a winding mechanism and an ejection mechanism. The middle section of the steel nail 11 is fixedly connected to the steel rope 12. The tip of the steel nail 11 is inclined towards the ground. The ejection mechanism includes a compression cylinder 13 and an airbag 14. The compression cylinder 13 is connected to the airbag 14 and is used to inflate the airbag 14. The airbag 14 is closely attached to the tail end of the steel nail 11 and is used to eject the steel nail 11 into the ground. The winding mechanism includes a winding roller 15 and a motor. The steel rope 12 is wound on the winding roller 15 and the end of the steel rope 12 is fixed to the winding roller 15. A second pressure sensor 16 is arranged at the position of half the height of the water retaining panel 5 from the ground. The second pressure sensor 16 is electrically connected to the switch of the compression cylinder 13. When the liquid level height of the flood rises to half the height of the gate leaf 2, due to the second pressure sensor 16 being subjected to the flood pressure, each group of compression cylinders 13 is automatically triggered to open to quickly inflate the airbag 14. The airbag 14 ejects the steel nail 11, and the winding roller 15 automatically unwinds. When the steel nail 11 is driven into the ground for a certain distance and the steel rope 12 is completely released and straightened, the steel nail 11 and the steel rope 12 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 11, drive the winding roller 15 to wind up by the motor and reset the steel nails 11, and finally the staff fills the steel nail holes on the ground.

[0031] A liquid level sensor and a timer are arranged on the water retaining panel 5. 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, so as to facilitate the staff to regularly analyze the local flood season situation, and thus improve the flood control and prevention wall targeted.

[0032] A verticality detector is arranged between the water retaining panel 5 and the backwater panel 6. The verticality detector is electrically connected to the remote control system. Since the flood control and prevention wall may tilt after being impacted by the flood, the verticality detector can be used to detect whether the gate leaf 2 is perpendicular to the ground before the gate leaf 2 enters the retaining wall groove 4 at the end of the flood season, so as to reflect the fit degree between the gate leaf 2 and the retaining wall groove 4, enabling the staff to know whether the gate leaf 2 can completely enter the groove 4, and further know whether the section where the gate leaf 2 is located affects the normal passage of pedestrians and vehicles. If the gate leaf 2 has a certain inclination angle with the ground and cannot be completely hidden in the retaining wall groove 4, the staff can timely learn the abnormal situation of the gate leaf 2, and thus carry out corresponding repairs.

[0033] A guide rail is arranged inside the vertical beam, and a pulley is arranged on the side wall of the door leaf 2. The pulley is slidably matched with the guide rail.
