A hidden flood control device that can quickly form a barrier effect

Abstract

The present invention relates to a concealed flood control device that can quickly form a barrier effect. The flood control wall uses a hydraulic cylinder placed on the back of the door leaf to complete the horizontal rotation of the wall. During the non-flood season, it can be completely hidden in the retaining wall, 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 to operate. 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, combined with 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 invention relates to the field of river ecological restoration and management and flood control on both sides of a river, and in particular to a hidden flood control device that can quickly form a barrier effect. Background Art

[0002] Most urban underground spaces and civil air defense projects install flood-proof gates at the highest point of the entrance and prepare sufficient flood-prevention sandbags to prevent heavy and concentrated rainfall from exceeding the design capacity of the original drainage system, causing water accumulation at the entrance of the underground parking lot to exceed the drainage flow and become waterlogging, resulting in man-made disasters.

[0003] However, most of the gates configured by the "flood control gates" are temporary facilities, which are usually idle and require space for storage. They are also extremely inconvenient to transport, install and use, and require a lot of manpower and material resources. Once a major flood disaster occurs, the water source cannot be blocked in time due to reasons such as transportation and equipment maintenance of the "flood control gates", resulting in huge and tragic 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 floods occur and flood control is needed, it is necessary to temporarily transport the columns and baffles, install the columns on sockets or column nails, and install baffles between the columns to form a flood control wall. The transportation process is time-consuming and labor-intensive, and the installation and disassembly process is cumbersome. Summary of the invention

[0004] In view of the above content, in order to solve the above problems, a hidden flood prevention device that can quickly form a barrier effect is provided, including a retaining wall, a door leaf and a hydraulic cylinder, characterized in that: there are two retaining walls, the two retaining walls are arranged on the roadside on the same side of the flood prevention section, and a space for accommodating the door leaf is formed between the two retaining walls, one end of the door leaf and one end of the hydraulic cylinder are hinged on the inner wall of the same retaining wall, and the door leaf includes a water retaining panel and a back water panel; the telescopic shaft of the hydraulic cylinder is rotatably connected to the back water panel, the hydraulic cylinder is electrically connected to the remote control system, and the hydraulic cylinder is used to drive the door leaf to open and rotate around its hinge point; in the flood season, the door leaf can be rotated to the flood prevention section and perpendicular to the road surface to block floods, and in the non-flood season, the door leaf can be rotated into and hidden in the space without affecting the free passage of pedestrians and vehicles.

[0005] Furthermore, a waterproof camera is arranged on the top of the water retaining panel, and the waterproof camera is electrically connected to the remote control system and the display screen, and the waterproof camera can be rotated at multiple angles; the waterproof camera is electrically connected to the remote control system and the display screen, and can be used to observe flood conditions, monitor and record in real time, and facilitate staff to detect abnormalities.

[0006] Further, a drying device is provided between the water retaining panel and the back water panel and inside the space. The drying device is electrically connected to a remote control system. The drying device is a heating coil or a resistance wire. The drying device can be used to dry the gate leaf, the hydraulic cylinder and other components in the box after the flood season ends, preventing the equipment components from rusting.

[0007] Further, a cavity is provided inside the gate leaf, and several groups of reinforcement devices are provided in the cavity. 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 faces vertically 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 pressure sensor is provided at the position of half the height of the gate leaf's water retaining panel from the ground. The pressure sensor is electrically connected to the switch of the compression cylinder. When the liquid level of the flood rises to half the height of the gate leaf, due to the flood pressure on the pressure sensor, each group of compression cylinders is automatically triggered to start inflating the airbag quickly. The airbag ejects the steel nails, and the winding roller automatically unwinds. When the steel nails are driven into the ground for a certain distance and the steel ropes are all released and straightened, the steel nails and steel ropes firmly fix the gate leaf, enhancing the stability of the gate leaf and preventing 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. Finally, the staff fills the steel nail holes on the ground.

[0008] Further, 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 or stepped. Since the pressure on the gate leaf from the flood 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 when it impacts the flood control and prevention wall is also high or low, 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 of the entire gate leaf is approximately an isosceles right triangle, or one side of the water retaining panel of the gate leaf is stepped, which is beneficial to enhancing the impact resistance of the entire gate leaf.

[0009] Further, 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. The data in the data memory can be synchronously transmitted to the 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 improve the flood control and prevention wall accordingly.

[0010] Furthermore, a verticality detector is arranged between the water retaining panel and the back water panel, and the verticality detector is electrically connected to the remote control system. Since the flood control wall may tilt after being impacted by the flood, the verticality detector can be used to detect whether the door leaf is perpendicular to the ground before the door leaf enters the retaining wall space at the end of the flood season, thereby reflecting the fit between the door leaf and the retaining wall space, so that the staff can know whether the door leaf can completely enter the space, and further know 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 space, the staff can promptly know the abnormal situation of the door leaf and make corresponding maintenance.

[0011] Furthermore, a door edge water stop is provided at one end of the door leaf away from the hinge point.

[0012] Furthermore, a slide rail is arranged at the bottom of the space, and a pulley is arranged at the bottom of the door leaf, and the pulley is slidably matched with the slide rail.

[0013] Furthermore, a water-stop cover plate for maintenance is provided on the top of the hydraulic cylinder.

[0014] 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.

[0015] Furthermore, the retaining wall, door leaves and hydraulic cylinder are provided in two groups and are respectively arranged on both sides of the flood control section. The two groups of door leaves are located on the same straight line after being opened and rotated, and the two groups of door leaves are connected by a door side water stop.

[0016] The beneficial effects of the present invention are:

[0017] The present invention drives the door leaf to rotate in and out in the space between the two retaining walls through a hydraulic cylinder. During the flood season, the door leaf can be rotated to the flood control section and perpendicular to the road surface to block floods. During the non-flood season, the door leaf can be rotated into and hidden in the space without affecting the free passage of pedestrians and vehicles. This solves the technical problem that traditional flood control walls need to occupy space for storage and are extremely inconvenient to transport, install and use.

[0018] By setting up a waterproof camera that can rotate at multiple angles, it is used to observe the flood situation, monitor and record in real time, and help staff detect abnormalities; by setting up a drying device, the door leaves, hydraulic cylinders and other parts in the box can be dried after the flood season to prevent rusting of equipment parts.

[0019] By setting up a strengthening device for the gate leaf, when the liquid level of the flood rises to half of the height of the gate leaf, the pressure sensor automatically triggers the compression cylinder to start inflating the airbag rapidly. The airbag ejects 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 knocked down by the flood.

[0029] A waterproof camera 6 is arranged on the top of the water retaining panel 4, and the waterproof camera 6 is electrically connected to the remote control system and the display screen. The waterproof camera 6 can rotate at multiple angles; the waterproof camera 6 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 staff to find abnormalities.

[0030] A drying device is arranged between the water retaining panel 4 and the water back panel 5, and inside the space. The drying device is electrically connected to the remote control system and is a heating coil or a resistance wire. The drying device can be used to dry the door leaves, hydraulic cylinders and other components in the box after the flood season is over to prevent rusting of equipment components.

[0031] A cavity 7 is arranged inside the gate leaf 2, and several groups of reinforcement devices are arranged in the cavity 7. The reinforcement device includes a steel nail 8, a steel rope 9, a winding mechanism and an ejection mechanism. The middle section of the steel nail 8 is fixedly connected to the steel rope 9, and the tip of the steel nail 8 is vertically oriented towards the ground. The ejection mechanism includes a compression cylinder 10 and an airbag 11. The compression cylinder 10 is connected to the airbag 11 and is used to inflate the airbag 11. The airbag 11 is closely attached to the tail end of the steel nail 8 and is used to eject the steel nail 8 into the ground. The winding mechanism includes a winding roller 12 and a motor. The steel rope 9 is wound on the winding roller 12 and the end of the steel rope 9 is fixed to the winding roller 12. A pressure sensor 13 is arranged at the position of half the height of the water retaining panel 4 from the ground. The pressure sensor 13 is electrically connected to the switch of the compression cylinder 10. When the liquid level height of the flood rises to half the height of the gate leaf 2, due to the flood pressure on the pressure sensor 13, each group of compression cylinders 10 is automatically triggered to open to quickly inflate the airbag 11. The airbag 11 ejects the steel nail 8, and the winding roller 12 automatically unwinds. When the steel nail 8 is driven into the ground for a certain distance and the steel rope 9 is fully released and straightened, the steel nail 8 and the steel rope 9 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 8, drive the winding roller 12 to wind up by the winding roller motor and reset the steel nails 8. Finally, the staff fills the steel nail holes on the ground.

[0032] The thickness of the gate leaf 2 gradually increases from top to bottom, and one side of the water retaining panel 4 of the gate leaf 2 is inclined or stepped. 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 or 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 4 of the gate leaf 2 is inclined, that is, the side surface of the entire gate leaf 2 is approximately an isosceles right triangle, or one side of the water retaining panel 4 of the gate leaf 2 is stepped, which is beneficial to enhancing the impact resistance of the entire gate leaf 2.

[0033] A liquid level sensor and a timer are arranged on the water retaining panel 4. 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 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.

[0034] A verticality detector is arranged between the water retaining panel and the back water panel, and the verticality detector is electrically connected to the remote control system. Since the flood control wall may tilt after being impacted by the flood, the verticality detector can be used to detect whether the door leaf 2 is perpendicular to the ground before the door leaf 2 enters the retaining wall space at the end of the flood season, thereby reflecting the fit between the door leaf 2 and the retaining wall space, so that the staff can know whether the door leaf 2 can completely enter the space, and further know whether the section where the door leaf 2 is located affects the normal passage of pedestrians and vehicles. If the door leaf 2 has a certain inclination angle with the ground and cannot be completely hidden in the retaining wall space, the staff can promptly know the abnormal situation of the door leaf and make corresponding maintenance.

[0035] A door edge water stop 14 is provided at one end of the door leaf 2 away from the hinge point.

[0036] A slide rail is arranged at the bottom of the space, and a pulley is arranged at the bottom of the door leaf 2, and the pulley is slidably matched with the slide rail.
