A sealed barrier type hydraulic emergency flood control wall for flood control and prevention

Abstract

The present invention relates to a sealed barrier type hydraulic emergency flood control wall for flood prevention and control. The flood control wall uses a hydraulic cylinder placed on the back of a door leaf to complete the lifting of the wall. After being laid down, it is completely embedded in the road surface. The panel is provided with anti-slip material, which does not affect the passage of vehicles and pedestrians. The lifting of the flood control wall can be controlled by electric, manual, remote control, induction and remote methods, and the operation is convenient and fast. It solves the technical problems that traditional flood control walls need to occupy space for storage, are extremely inconvenient to transport, install and use, and cannot block the water source in time in the event of a major flood disaster due to transportation and equipment maintenance, resulting in huge and tragic losses.

Description

Technical Field

[0001] The present invention relates to the fields of river ecological restoration and management and flood control and prevention on both sides of a river, and in particular to a sealed barrier type hydraulic emergency flood control wall for flood control and prevention. 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 the water accumulation at the entrance of the underground parking lot to exceed the drainage flow and become waterlogging, which will become a man-made disaster.

[0003] However, most of the gates currently used for flood control are temporary facilities that are usually idle, require space for storage, and are extremely inconvenient to transport, install, and use. They also require a large amount of manpower and material resources. In the event of a major flood disaster, the transportation and equipment maintenance of the flood control gates cannot promptly block the water source, resulting in huge and devastating 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 require temporary transport of columns and baffles when flood control is needed. The columns are then installed on sockets or studs, and baffles are installed 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 sealed barrier type hydraulic emergency flood control wall for flood prevention and control is provided, comprising a box body, a door leaf and a drive assembly, characterized in that: the box body is arranged in a pit below the ground, the door leaf and the drive assembly are located in the box body, the door leaf comprises a water retaining panel and a back water panel, one end of the door leaf is fixedly connected to the bottom shaft, the bottom shaft is rotatably mounted on the support steel plate, and the support steel plate is fixed to the bottom wall of the box body through the bottom shaft support assembly; the drive assembly comprises two hydraulic cylinders symmetrically arranged in the pit, the hydraulic cylinders are both fixed to the bottom wall of the box body through hydraulic cylinder support assemblies, the hydraulic cylinders are both electrically connected to the remote control system, the telescopic shafts of the hydraulic cylinders are both hinged to the ear plates fixedly arranged in the middle of the back water panel, and the hydraulic cylinders are 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 and used to block floods, and during the non-flood season, the door leaf can be rotated to a horizontal state and connected parallel to the road surface without affecting the free passage of pedestrians and vehicles.

[0005] Furthermore, a first pressure sensor is provided on the surface of the middle section of the water retaining panel, and 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 extension and retraction 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 extension of the telescopic shaft, so that the door leaf rotates to a 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 for a period of time, the hydraulic cylinder controls the shortening of the telescopic shaft, and the door leaf rotates to a horizontal state and falls down and embeds into the road surface, is on the same plane as the road surface and is connected to the road surface, and can be used as a passage for pedestrians and vehicles to pass freely.

[0006] Furthermore, the first pressure sensor uses a segmented triggering method to raise the door leaf, 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 vertical. Since the door leaf rotates to 90 degrees after it is fully raised, when a flood comes, the pressure value borne by the first pressure sensor reaches the trigger value for the first time, and the hydraulic cylinder controls the door leaf to rotate to an angle of 90 / n degrees. As the flood slowly rises, the pressure value borne by the first pressure sensor reaches the trigger value for the second time, and the hydraulic cylinder controls the door leaf to rotate to an angle of 2*90 / n degrees, and so on, until the door leaf rotates 90 degrees to a vertical state, where n is an integer greater than 3. Since the amount of flood water varies during each flood season, the door leaf does not necessarily need to be in a vertical state every time. The above-mentioned segmented triggering method to raise the door leaf can save the driving force of the hydraulic cylinder and reduce the wear of the hydraulic cylinder telescopic shaft. At the same time, the staff can control the segmented raising of the door leaf to facilitate the maintenance of various parts of the door leaf.

[0007] Furthermore, a drying device is provided between the water retaining panel and the back water panel, and at the bottom of the box body. 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 body after the flood season is over to prevent the equipment components from rusting.

[0008] Furthermore, a flexible filter screen or water retaining cloth is provided at one end of the back water panel away from the bottom axis and at the top end of the side wall of the box away from the bottom axis. The filter screen or water retaining cloth is equal to the width of the box in the front and rear directions. When the door leaf falls over and embeds into the road surface, the filter screen or water retaining cloth is folded inside the box. When the door leaf rotates to a vertical state and blocks the flood, the filter screen or water retaining cloth opens and completely covers the box, thereby preventing rainwater, mud, sand, gravel, leaves and other debris from entering the box and causing pollution or blockage.

[0009] Furthermore, two left and right cavities are set inside the door leaf, and reinforcement devices are respectively set in the left and right cavities, the reinforcement device includes a steel nail, a steel rope, a winding mechanism and a catapult mechanism, the middle section of the steel nail is fixedly connected to the steel rope, the tip of the steel nail is inclined toward the ground, the catapult 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 close to the tail end of the steel nail and is used to catapult 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, and a second pressure sensor is set at a position where the door leaf water retaining panel is half the height of the ground, and the second 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 door leaf, the second pressure sensor is subjected to the flood pressure, which automatically triggers each group of compression cylinders to open and quickly inflate the airbags. The airbags pop out the steel nails, and the winding rollers automatically unwind. When the steel nails shoot into the ground for a certain distance, all the steel ropes are released and straightened. The steel nails and steel ropes firmly fix the door leaf to enhance the stability of the door leaf and prevent it from being washed down by the flood. When the flood season is over, the staff can use tools to pull out the steel nails, and use the winding roller motor to drive the winding roller to rewind and reset the steel nails. Finally, the staff will fill the steel nail holes on the ground.

[0010] Furthermore, a liquid level sensor and a timer are provided on the water retaining panel, and the liquid level sensor and the timer are electrically connected to a data storage device. The data in the data storage device 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 and flood season duration of the flood, and automatically store the data, thereby facilitating the staff to regularly analyze the local flood season conditions, and thus make targeted improvements to the flood control wall.

[0011] Furthermore, the thickness of the door leaf gradually increases from top to bottom, and one side of the water retaining panel of the door leaf is inclined. Since the pressure on the door leaf gradually increases from top to bottom when a flood arrives, and the amount of water in each flood is uncertain, the height of the flood water level when impacting the flood control wall also varies. Therefore, the lower part of the door leaf of the flood control wall often bears greater water pressure. Therefore, the thickness of the door leaf gradually increases from top to bottom. Specifically, one side of the water retaining panel of the door leaf is inclined, that is, the side surface of the entire door leaf is approximately an isosceles right triangle, which is conducive to enhancing the impact resistance of the entire door leaf.

[0012] Furthermore, reinforcement plates are provided on both sides of the supporting steel plate.

[0013] Furthermore, a water-stopping horizontal plate and a water-stopping vertical plate in an inverted "T" shape are provided on one side of the supporting steel plate close to the side wall of the pit.

[0014] Furthermore, angle steel is provided at the connection between the bottom shaft and the supporting steel plate.

[0015] Furthermore, a P-shaped water-stop rubber is provided on the water-stop transverse plate.

[0016] Furthermore, a water-stop cover plate for maintenance is provided on the side wall close to the bottom shaft.

[0017] The beneficial effects of the present invention are:

[0018] The present invention drives the door leaves to rotate around the bottom axis through a hydraulic cylinder; during the flood season, the door leaves can be rotated to a vertical state and used to block floods; during the non-flood season, the door leaves can be rotated to a horizontal state and connected parallel to the road surface without affecting the free passage of pedestrians and vehicles, solving the technical problems that traditional flood control walls need to occupy space for storage and are extremely inconvenient to transport, install and use.

[0019] By arranging a first pressure sensor on the surface of the middle section of the water retaining panel, the flood prevention wall can judge whether the flood season is coming according to the pressure borne by the water retaining panel, so that when the flood season comes, the hydraulic cylinder is automatically opened and the door leaf is driven to rotate to a vertical state for flood prevention, and after the flood season is over, the hydraulic cylinder is opened again and the door leaf is driven to rotate to a horizontal state and connected parallel to the road surface, without affecting the free passage of pedestrians and vehicles; by arranging a drying device, the door leaf, hydraulic cylinder and other components in the box can be dried after the flood season is over to prevent the equipment components from rusting.

[0020] By setting up a door leaf reinforcement device, when the liquid level of the flood rises to half the height of the door leaf, the second pressure sensor automatically triggers the compression cylinder to open 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 door leaf to enhance the stability of the door leaf and prevent it from being washed down by the flood. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The advantages, features and methods of achieving the above objects of the present invention will become clear from the accompanying drawings and the following detailed description.

[0028] Example:

[0029] Combine Figure 1-4 A sealed barrier type hydraulic emergency flood control wall for flood prevention and control, comprising a box body 1, a door leaf 2 and a drive assembly, characterized in that: the box body 1 is set in a pit below the ground, the door leaf 2 and the drive assembly are located in the box body 1, the door leaf 2 includes a water retaining panel 3 and a water back panel 4, one end of the door leaf 2 is fixedly connected to the bottom shaft 5, the bottom shaft 5 is rotatably mounted on the support steel plate 6, and the support steel plate 6 is fixed to the bottom wall of the box body 1 through the bottom shaft support assembly 7; the drive assembly includes a symmetrical arrangement in the pit There are two hydraulic cylinders 8 inside, and the hydraulic cylinders 8 are fixed to the bottom wall of the box body 1 through the hydraulic cylinder support assembly 9. The hydraulic cylinders 8 are electrically connected to the remote control system. The telescopic shafts of the hydraulic cylinders 8 are hinged to the ear plates 10 fixedly arranged in the middle of the back water panel 4. The hydraulic cylinders 8 are used to drive the door leaf 2 to rotate around the bottom axis 5; during the flood season, the door leaf 2 can be rotated to a vertical state and used to block floods. During the non-flood season, the door leaf 2 can be rotated to a horizontal state and connected parallel to the road surface, without affecting the free passage of pedestrians and vehicles.

[0030] A first pressure sensor 11 is provided on the surface of the middle section of the water retaining panel 3, and the first pressure sensor 11 is electrically connected to the hydraulic cylinder 8. The first pressure sensor 11 is used to detect the pressure borne by the water retaining panel 3 so as to automatically control the extension and contraction 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 extension of the telescopic shaft, so that the door leaf 2 rotates to a 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 for a period of time, the hydraulic cylinder 8 controls the shortening of the telescopic shaft, and the door leaf 2 rotates to a horizontal state and falls down and embeds into the road surface, is on the same plane as the road surface and is connected to the road surface, and can be used as a passage for pedestrians and vehicles to pass freely.

[0031] The first pressure sensor 11 uses a segmented triggering method to raise the door leaf 2. That is, when the pressure value of the first pressure sensor 11 reaches the trigger value, the hydraulic cylinder 8 controls the door leaf 2 to rotate to a certain angle instead of being completely vertical. Since the door leaf 2 rotates to 90 degrees after it is fully raised, when a flood comes, the pressure value of the first pressure sensor 11 reaches the trigger value for the first time, and the hydraulic cylinder 8 controls the door leaf 2 to rotate to an angle of 90 / n degrees. As the flood slowly rises, the pressure value of the first pressure sensor 11 reaches the trigger value for the first time, and the hydraulic cylinder 8 controls the door leaf 2 to rotate to an angle of 90 / n degrees. When the trigger value is reached for the second time, the hydraulic cylinder 8 controls the door leaf 2 to rotate at an angle of 2*90 / n degrees, and so on, until the door leaf 2 rotates 90 degrees to a vertical state, wherein n is an integer greater than 3; since the amount of flood water varies during each flood season, the door leaf 2 does not necessarily need to be in a vertical state every time. The above-mentioned segmented triggering method for raising the door leaf 2 can save the driving force of the hydraulic cylinder 8 and reduce the wear of the hydraulic cylinder telescopic shaft. At the same time, the staff can control the segmented raising of the door leaf 2 to facilitate the staff to inspect and repair various parts of the door leaf 2.

[0032] A drying device is provided between the water retaining panel 3 and the water back panel 4, and at the bottom of the box body 1. The drying device is electrically connected to the remote control system. The drying device is a heating coil or a resistance wire. The drying device can be used to dry the door leaf, hydraulic cylinder and other components in the box body after the flood season is over to prevent the equipment components from rusting.

[0033] A flexible filter screen or water retaining cloth 19 is provided at one end of the back water panel 4 away from the bottom axis 5 and at the top of the side wall of the box body 1 away from the bottom axis 5. The filter screen or water retaining cloth 19 is equal to the width of the box body 1 in the front and rear directions. When the door leaf 2 falls over and embeds into the road surface, the filter screen or water retaining cloth 19 is folded in the box body 1. When the door leaf 2 is rotated to a vertical state and blocks the flood, the filter screen or water retaining cloth 19 opens and completely covers the box body 1, thereby preventing rainwater, mud, sand, gravel, leaves and other debris from entering the box body 1 and causing pollution or blockage.

[0034] Two left and right cavities 12 are set inside the door leaf 2, and reinforcement devices are respectively set in the left and right cavities 12, and the reinforcement device includes a steel nail 13, a steel rope 14, a winding mechanism and a ejection mechanism. The middle section of the steel nail 13 is fixedly connected to the steel rope 14, and the tip of the steel nail 13 is inclined toward 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 close 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 on 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 set at a position where the water retaining panel 3 is half the height of the ground. The second pressure sensor 18 is electrically connected to the switch of the compression cylinder 15. When the liquid level of the flood rises to half the height of the door leaf 2, the second pressure sensor 18 is subjected to the flood pressure, which automatically triggers each group of compression cylinders 15 to open and quickly inflate the airbag 16. The airbag 16 pops out the steel nail 13, and the winding roller 17 automatically unwinds. When the steel nail 13 shoots into the ground for a distance, the steel rope 14 is completely released and straightened. The steel nail 13 and the steel rope 14 firmly fix the door leaf 2 to enhance the stability of the door leaf 2 and prevent it from being washed down by the flood; when the flood season is over, the staff can use tools to pull out the steel nail 13, and drive the winding roller 17 to rewind and reset the steel nail through the winding roller motor. Finally, the staff fills the steel nail hole on the ground.

[0035] A liquid level sensor and a timer are provided on the water retaining panel 4, and the liquid level sensor and the timer are electrically connected to a data storage device. The data in the data storage device 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 and flood season duration of the flood, and automatically store the data, so as to facilitate the staff to regularly analyze the local flood season conditions, and thus make targeted improvements to the flood control wall.

[0036] Furthermore, the thickness of the door leaf 2 gradually increases from top to bottom, and one side of the water retaining panel 4 of the door leaf 2 is inclined. Since the pressure on the door leaf 2 gradually increases from top to bottom when a flood arrives, and the amount of water in each flood is uncertain, the liquid level of the flood when it impacts the flood control wall also varies. Therefore, the lower part of the door leaf 2 of the flood control wall often bears greater water pressure. Therefore, the thickness of the door leaf 2 gradually increases from top to bottom. Specifically, one side of the water retaining panel 4 of the door leaf 2 is inclined, that is, the side surface of the entire door leaf 2 is approximately an isosceles right triangle, which is conducive to enhancing the impact resistance of the entire door leaf 2.

[0037] Reinforcement plates are provided on both sides of the support steel plate 6 .

[0038] The support steel plate 6 is provided with an inverted "T"-shaped water-stopping horizontal plate and a water-stopping vertical plate on one side close to the side wall of the pit.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
