Description

Technical Field

[0001] This invention relates to the field of flood control barrier technology, and in particular to a telescopic folding intelligent flood control barrier with a real-time water level monitoring system. Background Technology

[0002] Flood barriers, as an important urban flood control infrastructure, are widely used for water protection in low-lying and flood-prone areas such as underground parking garage entrances, subway station entrances, underpasses, underground shopping malls, and civil defense projects. In recent years, with the increasing frequency of extreme rainfall events due to global climate change, urban flooding disasters have become more severe, placing higher demands on the response speed, automation level, and daily accessibility of flood control facilities.

[0003] Currently, existing flood control and water-retaining facilities on the market mainly include traditional sandbag stacked retaining walls, insert-plate combined retaining walls, flap-type automatic retaining dams, and lifting flat retaining gates. However, these existing technologies generally suffer from drawbacks such as crude structural design, low automation, and long response times, making it difficult to meet the demands of modern urban flood control for rapid response and intelligent management. Especially for major traffic arteries with high traffic volume and dense pedestrian flow, traditional flood control facilities often need to be temporarily moved and assembled during the flood season. This not only consumes a lot of manpower and resources but also, due to the cumbersome installation and operation, easily leads to missing the best flood control opportunity, resulting in backflow of floodwaters and causing significant economic losses and safety hazards.

[0004] While some existing liftable flood control barriers have incorporated motor drives and screw transmissions for automated lifting, their structures are mostly single, integral panels. When raised, they occupy significant vertical space, placing stringent requirements on installation site height. Furthermore, the barrier's movement trajectory during lifting is limited, preventing segmented folding and storage. This often results in the barrier extending too far above ground level when fully raised, interfering with the normal use of surrounding facilities. More importantly, most existing products lack intelligent water level monitoring and automatic control functions, failing to autonomously activate flood control in the early stages of an emergency, still relying on manual inspections and on-site operations, indicating a severe deficiency in intelligence. Therefore, a telescopic, foldable, intelligent flood control barrier with a real-time water level monitoring system is needed to address these issues. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic and foldable intelligent flood control barrier with a real-time water level monitoring system includes: The base includes two base plates embedded in the ground. Side supports are provided on the left and right sides of the bottom end of the base plates. The inner sides of the bottom ends of the two side supports are connected and fixed by reinforcing ribs. The column pile section includes column covers symmetrically fixed on both sides of the top of the base plate. Each of the four corners of the inner wall of the column cover is provided with a support column, and the top of the four support columns is connected to a top plate. The driving part includes a fixing plate fixed to the top of the top plate, a motor installed at the bottom of the fixing plate, and the shaft end of the motor passing through the top plate and the fixing plate and connected to the driving wheel. The driving wheel is connected to the driven wheel via a connecting belt. The shaft end of the driven wheel passes through the top plate via a through hole and is connected to the lead screw. The top of the lead screw is rotatably mounted on the bottom of the top plate via a bearing seat. The bottom of the lead screw is rotatably mounted on the inner wall of the column cover via a bearing seat. A threaded slider is threaded on the surface of the lead screw. The transmission part includes an outer frame plate that is connected and fixed to the threaded slider. The surface of the outer frame plate is fixed to the surface of the middle frame plate by a support plate and bolts. The surface of the middle frame plate is provided with a guide groove for sliding, and two pulley bushings A are slidably arranged inside the guide groove. A handle is movably mounted on the surface of each of the two pulley bushings A. A pulley bushing B is movably mounted on the other end of each of the two handles. The pulley bushings B are slidably installed inside the inner frame plate through a sliding groove. A rotating shaft is also connected to the side of the handle, and the rotating shaft is rotatably installed inside the fixed seat. The upper and lower handles are arranged in parallel. The baffle section includes an upper baffle assembly and a lower baffle assembly that are arranged in contact with each other. The upper baffle assembly is connected to the two fixed seats on its side. The lower baffle assembly includes a pressure-bearing baffle. The pressure-bearing baffle is wrapped and connected to a protective plate B on both sides. Each side of the protective plate B is connected to two receiving shafts. Both sets of receiving shafts are rotatably connected to pulley bushings C. One pulley bushing C is slidably installed in the vertical groove of the middle frame plate, and the other pulley bushing C is slidably installed in the vertical groove of the outer frame plate. The inner side of the column cover is provided with a strip-shaped slot that allows the upper baffle assembly and the lower baffle assembly to move. The flood control baffle also includes a control unit, which is connected to the motor. The motor drives the lead screw to rotate, which in turn drives the transmission part to move through the threaded slider, thereby driving the baffle part to rise vertically from the base to a preset height. The raised baffle part forms a sealed water-blocking structure with the column cover and the base plate. When the motor rotates in the reverse direction, the baffle part descends and folds into the corresponding area of ​​the base, and the upper surface of the baffle part is flush with the upper surface of the base plate.

[0007] Preferably, the base is buried below the floor of the passage, the column cover is set on both sides of the passage and connected to the side wall, the bottom plate is buried below the ground, and the baffle part forms a water barrier perpendicular to the ground when it is raised, and restores the ground to a flat state when it is lowered.

[0008] Preferably, it also includes a water level monitoring unit, which is signal-connected to the control unit. When the water level is detected to reach the warning value, the control unit automatically starts the motor to drive the baffle to rise and block the water.

[0009] Preferably, the upper baffle assembly includes a heightening baffle, with protective plates A fastened to the left and right sides of the heightening baffle by bolts, an upper flat plate connected to the top of the heightening baffle, and a rubber strip A connected to the bottom of the heightening baffle; a rubber strip B is connected to the bottom of the pressure-bearing baffle, and a mating groove adapted to the rubber strip A is opened at the top of the pressure-bearing baffle. The heightening baffle and the pressure-bearing baffle achieve sealing when they are joined end to end through the fitting of the rubber strip A and the mating groove.

[0010] Preferably, the control unit includes a field control module and a remote control module for realizing field control and remote control; the control unit also responds to manually triggered control commands to start the motor to perform a water-blocking and raising action or a reset and lowering action.

[0011] Preferably, the baffle is flush with the ground when it is lowered and folded, so as not to affect the passage of vehicles and pedestrians.

[0012] Preferably, a sealing strip is provided between the base plate and the baffle portion, and a sealing strip is also provided between the baffle portion and the column cover. After the motor drives the baffle portion to rise, the sealing strips fit tightly together to block water from seeping through the gaps and form a vertical water barrier.

[0013] Preferably, when the motor drives the baffle portion to rise, the handle of the transmission portion rotates, causing the lower baffle assembly to move laterally relative to the upper baffle assembly until the upper baffle assembly and the lower baffle assembly are parallel. Then, the two upper baffle assemblies and the lower baffle assembly rise synchronously to be perpendicular to the ground.

[0014] Preferably, when the motor drives the baffle portion to descend and reset, the upper baffle assembly and the lower baffle assembly overlap in parallel, and the upper surface of the pressure-bearing baffle and the upper surface of the upper baffle assembly together form a flat surface. This flat surface is in contact with the upper surface of the base plate and is flush with the ground.

[0015] Preferably, the threaded slider is fixedly connected to the outer frame plate. When the lead screw rotates, it drives the outer frame plate and the baffle to rise and fall through the threaded slider. Both sides of the baffle are connected to the corresponding lead screw through the transmission part.

[0016] This invention has at least the following beneficial effects: 1. This invention, by pre-embedding the base below the ground of the passageway and setting up the coordinated cooperation of the column pile part, drive part, transmission part and baffle part, allows the equipment to be completely stored below the ground in the non-flood season. The upper plate and the bottom plate are flush with the ground, requiring no manual assembly or disassembly, and does not affect the normal passage of vehicles and pedestrians. It solves the technical problems of traditional flood control facilities that require temporary handling and assembly, occupy ground space and affect passage.

[0017] 2. In this invention, the upper baffle assembly and the lower baffle assembly are stacked vertically. During the process of the threaded slider driving the outer frame plate and the middle frame plate to rise, the inclined section of the guide groove of the middle frame plate forces the pulley bushing A to produce a lateral displacement. After being transmitted by two parallel handles, the upper baffle assembly is driven to move horizontally to the outside, so that the two baffles automatically change from the stacked state to the vertical side-by-side state, realizing the automatic conversion between folding and storage and unfolding to block water, effectively reducing the height requirements of the equipment for installation space.

[0018] 3. By setting two rods parallel and of equal length, and cooperating with the sliding constraint of the pulley bushing B in the inner frame plate groove, the present invention forms a stable parallel four-bar linkage mechanism, so that the fixed seat and the upper baffle assembly fixed thereto always maintain a vertical posture and do not tilt during the lifting and unfolding process, ensuring that the sealing strip between the baffle and the column cover can be uniformly compressed, avoiding local sealing failure caused by the baffle tilt.

[0019] 4. In this invention, the lower baffle assembly slides with the vertical groove of the outer frame plate and the vertical groove of the middle frame plate through the receiving shaft and the pulley bushing C, respectively, so that the upper and lower ends of the lower baffle assembly are constrained at the same time, and always maintain a vertical posture during the lifting process. Together with the upper baffle assembly, it forms a flat water-blocking surface, ensuring the integrity of the water barrier and its resistance to water flow impact.

[0020] 5. This invention sets up a control unit connected to a motor control unit, which works in conjunction with a water level monitoring unit to collect water level data in real time. When the water level reaches the warning threshold, the control unit automatically starts the motor to drive the baffle to rise, realizing full automation of real-time water level monitoring and water blocking activation. No manual inspection or on-site operation is required, which greatly shortens the flood control response time and avoids the risk of flood backflow caused by human delays.

[0021] 6. Through the coordinated setup of the on-site control module and the remote control module, the present invention allows on-site personnel to perform raising, lowering and emergency stop operations via the waterproof button panel. Authorized personnel can also remotely send control commands via a mobile APP or a dedicated remote control, realizing a dual control mode of near field and remote control. Even when unattended, water blocking operations can be completed, effectively improving the adaptability and ease of operation of the equipment in various application scenarios.

[0022] 7. The present invention is an online, non-disassembly-required device. When the motor rotates forward, the lead screw drives the threaded slider to rise and complete the construction of the water barrier. When the motor rotates in reverse, the baffle part automatically folds back to be flush with the ground. The entire process does not require manual handling or assembly of any parts, which not only ensures rapid and effective water blocking during the flood season, but also ensures unobstructed passage during normal times.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] Reference Figure 1-10 A telescopic and foldable intelligent flood control barrier with a real-time water level monitoring system includes: The base 1 includes two base plates 13 embedded in the ground. Side supports 11 are provided on the left and right sides of the bottom end of the base plates 13. The inner sides of the bottom ends of the two side supports 11 are connected and fixed by reinforcing ribs 12. The column section 2 includes column covers 21 symmetrically fixed on both sides of the top of the base plate 13. Each of the four corners of the inner wall of the column cover 21 is provided with a support column 22, and the top of the four support columns 22 is connected to a top plate 23. The driving part 3 includes a fixing plate 31 fixed to the top of the top plate 23. A motor 32 is installed at the bottom of the fixing plate 31. The shaft end of the motor 32 passes through the top plate 23 and the fixing plate 31 and is connected and fixed to the driving wheel 33. The driving wheel 33 is connected to the driven wheel 35 through the connecting belt 34. The shaft end of the driven wheel 35 passes through the top plate 23 through the through hole. The bottom end of the top plate 23 is rotatably installed on the inner wall of the column cover 21 through the bearing seat. The screw 36 is threaded with a threaded slider 37. The transmission part 4 includes an outer frame plate 41 that is connected and fixed to the threaded slider 37. The surface of the outer frame plate 41 is fixed to the surface of the middle frame plate 42 by a support plate and bolts. The surface of the middle frame plate 42 is provided with a guide groove for sliding, and two pulley bushings A43 are slidably arranged inside the guide groove. A handle 44 is movably installed on the surface of each of the two pulley bushings A43. A pulley bushing B48 is movably installed on the other end of each of the two handles 44. The pulley bushing B48 is slidably installed inside the inner frame plate 47 through a sliding groove. A rotating shaft 45 is also connected to the side of the handle 44, and the rotating shaft 45 is rotatably installed inside the fixed seat 46. The upper and lower handles 44 are arranged in parallel. The baffle section 5 includes an upper baffle assembly 51 and a lower baffle assembly 52 that are arranged in contact with each other. The upper baffle assembly 51 is connected to two fixed seats 46 on its side. The lower baffle assembly 52 includes a pressure-bearing baffle 521. The pressure-bearing baffle 521 is wrapped and connected to a protective plate B522 on both sides. Both sides of the protective plate B522 are connected to two receiving shafts 523. Both sets of receiving shafts 523 are rotatably connected to pulley bushings C49. One pulley bushing C49 is slidably installed in the vertical groove of the middle frame plate 42, and the other pulley bushing C49 is slidably installed in the vertical groove of the outer frame plate 41.

[0028] The flood control baffle also includes a control unit, which is connected to the motor 32. The motor 32 drives the lead screw 36 to rotate, and drives the transmission part 4 to move through the threaded slider 37, so as to drive the baffle part 5 to rise vertically from the base 1 to a preset height. The raised baffle part 5 forms a sealed water-blocking structure with the column cover 21 and the base plate 13. When the motor 32 rotates in reverse, the baffle part 5 descends and folds into the corresponding area of ​​the base 1. The upper surface of the baffle part 5 is flush with the upper surface of the base plate 13. The control unit includes a field control module and a remote control module for realizing field control and remote control. The control unit also responds to manually triggered control commands to start the motor 32 to perform the water-blocking and raising action or the reset and lowering action.

[0029] The upper baffle assembly 51 includes a heightening baffle 511, with protective plates A512 fastened to the left and right sides of the heightening baffle 511 by bolts, and an upper plate 514 connected to the top of the heightening baffle 511.

[0030] The side of the heightening baffle 511 is fixed to the fixing seat 46 by bolts, and the inner side of the column cover 21 is provided with a strip-shaped slot for the upper baffle assembly 51 and the lower baffle assembly 52 to move.

[0031] The bottom of the heightening baffle 511 is connected to a rubber strip A513, and the top of the pressure baffle 521 is provided with a mating groove that matches the rubber strip A513, thereby improving the sealing effect when the heightening baffle 511 and the pressure baffle 521 are mated end to end.

[0032] The guide groove of the middle frame plate 42 is inclined, and the initial position of one of the pulley bushings A43 is located at the inclined position of the guide groove.

[0033] A rubber strip B524 is also provided at the bottom of the pressure baffle 521 for sealing.

[0034] A sealing strip is also provided between the base plate 13 and the baffle part 5, and a sealing strip is also provided between the baffle part 5 and the column cover 21, to block water from seeping through the gaps and form a vertical water barrier.

[0035] The following analysis and description of the device are based on several embodiments; Example 1: The present invention provides a telescopic and foldable intelligent flood control barrier with a real-time water level monitoring system. As an online fully automatic flood control device, it is preferably installed below the ground level in low-lying and flood-prone areas such as underground garage entrances, subway station entrances, underpasses, underground shopping mall passages, or civil defense project entrances. In non-flood seasons, the device is completely retracted below the ground level and does not affect the normal passage of vehicles and pedestrians.

[0036] Please see Figures 1 to 10 The structural diagram shown illustrates that the core structure of this invention consists of five functional modules: a base 1, a column pile 2, a drive unit 3, a transmission unit 4, and a baffle unit 5. The base 1 serves as the load-bearing foundation for the entire device and includes two symmetrically arranged base plates 13. These base plates 13 are made of high-strength steel plates and are embedded in the concrete foundation of the passageway. After installation, the upper surface of the base plate 13 remains flush with the ground surface. Side supports 11 are welded and fixed to the left and right sides of the bottom of the base plate 13. The side supports 11 are support leg structures made of steel profiles, and the inner sides of the bottom ends of the two side supports 11 are connected and fixed to each other by horizontally arranged reinforcing ribs 12. The reinforcing ribs 12 are welded to the side supports 11, thereby forming an integral frame base with high structural strength and anti-overturning ability, capable of withstanding the huge impact force of the water flow and the lateral water pressure after the baffle is raised.

[0037] The column pile parts 2 are symmetrically fixedly installed on both sides of the top of the base plate 13. The column cover 21 is a hollow box structure made of steel plate bending. Its bottom end is fixedly connected to the base plate 13 by anchor bolts. Four support columns 22 are vertically installed at the four corners of the inner wall of the column cover 21. The support column 22 is a cylindrical metal rod. Its bottom end is fixed to the upper surface of the base plate 13 by bolts. The top of the support column 22 is connected to a top plate 23 by bolts. Through the equidistant support of the four corner support columns 22, a stable installation space is formed inside the column cover 21, providing a support foundation for the drive part 3 and the transmission part 4. A vertical through-slot is opened on the inner side wall of the column cover 21 facing the baffle part 5. The slot runs through the entire height of the column cover 21. Its width is greater than the sum of the thicknesses of the upper baffle assembly 51 and the lower baffle assembly 52, ensuring that the two baffles can move freely up and down in the slot without interference from the side wall of the column cover 21.

[0038] The fixing plate 31 is welded or bolted to the upper surface of the top plate 23. The fixing plate 31 is a horizontally arranged flat plate structure used to support the weight of the motor 32. The motor 32 is preferably a three-phase asynchronous geared motor. Its housing is bolted to the bottom of the fixing plate 31. The shaft of the motor 32 is arranged upwards, and its shaft end passes through the top plate 23 and the fixing plate 31 from bottom to top and then extends upwards. It is connected and fixed to the center hole of the drive wheel 33 by a flat key or a shrink sleeve, thereby realizing the transmission of the output torque of the motor 32 to the drive wheel 33. The drive wheel 33 adopts a synchronous belt pulley structure, which is connected to the driven wheel by a connecting belt 34. 35 achieves synchronous transmission. The connecting belt 34 is preferably a toothed synchronous belt with high tensile strength and wear resistance to ensure accurate power transmission between the driving wheel 33 and the driven wheel 35 without slippage. The driven wheel 35 is located on one side of the driving wheel 33. The central shaft hole of the driven wheel 35 allows the top end of the lead screw 36 to pass through. The top driven wheel 35 of the lead screw 36 is fixed to the lead screw 36 by a key connection. The lead screw 36 passes through the top plate 23 from top to bottom. At this penetration position, a rolling bearing is installed between the outer wall of the lead screw 36 and the inner wall of the through hole of the top plate 23, which is rotatably installed at the bottom end of the top plate 23 as a bearing seat. Similarly, the lower end of the lead screw 36 is also rotatably mounted on the bottom of the inner wall of the column cover 21 through a bearing seat. With the support of the upper and lower bearing seats, the lead screw 36 is restricted to rotational freedom in the vertical axis direction, and cannot produce axial movement, thereby ensuring the smoothness of the rotational movement of the lead screw 36. A threaded slider 37 is fitted on the threaded surface of the lead screw 36. The inner hole of the threaded slider 37 is machined with an internal thread that matches the external thread of the lead screw 36. When the lead screw 36 rotates forward or backward under the drive of the motor 32, the threaded slider 37 moves in a straight line, rising or falling along the axial direction of the lead screw 36. In addition, in order to ensure that the threaded slider 37 only moves in a straight line and does not rotate with the lead screw 36, a vertical guide rail is provided on the inner wall of the column cover 21 in this embodiment. The outer wall of the threaded slider 37 slides in fit with the guide rail. The guide rail can effectively prevent the threaded slider 37 from rotating circumferentially.

[0039] The function of the transmission part 4 is to convert the vertically moving threaded slider 37 into the multi-segment folding and unfolding motion required by the baffle part 5. The outer frame plate 41 is a vertically arranged plate-shaped component. Its inner surface is fixedly connected to the outer wall of the threaded slider 37 by welding or bolts, so that it moves up and down synchronously with the threaded slider 37. The outer surface of the outer frame plate 41 is fixed to the surface of the middle frame plate 42 by a support plate and bolts. The support plate is an L-shaped bent plate with connecting holes. One right-angled surface of the support plate is attached to and welded to the surface of the outer frame plate 41, and the other right-angled surface is attached to and fastened to the surface of the middle frame plate 42 by bolts. This achieves a rigid connection between the outer frame plate 41 and the middle frame plate 42, making the two a linked whole.

[0040] The middle frame plate 42 is also a vertical plate with a guide groove for sliding on its surface. The guide groove is an oblong through groove, and its outline is smoothly connected by an inclined section at the top and a vertical section at the bottom. The width of the guide groove is adapted to the outer diameter of the pulley bushing A43, allowing the pulley bushing A43 to roll or slide freely in the guide groove. Two pulley bushings A43 are slidably arranged inside the guide groove. The pulley bushing A43 is a rolling bearing sleeve or wear-resistant bushing structure that is sleeved on the outer circumference of the pin. The two pulley bushings A43 are respectively set at two different positions at the top and bottom of the guide groove. Each pulley bushing A43 has a handle 44 movably installed on its surface through the pin, that is, one handle 44 at the top and one at the bottom. The two handles 44 are arranged in parallel and have the same length, forming a parallel four-bar linkage.

[0041] At the other end of the two handles 44, that is, the end away from the pulley bushing A43, pulley bushings B48 are respectively movably installed. The inner hole of the pulley bushing B48 is fitted onto the pin fixed to the end of the handle 44. Both pulley bushings B48 are slidably installed inside the groove of the inner frame plate 47. That is, the pulley bushings B48 are slidably installed inside the inner frame plate 47 through the groove. The inner frame plate 47 is a vertically fixed plate body, and its groove is a strip groove extending in the vertical direction. The pulley bushings B48 can only roll or slide in the up and down direction within the groove.

[0042] Therefore, when the threaded slider 37 drives the outer frame plate 41 and the middle frame plate 42 to move upward as a whole, due to the inclined section of the guide groove of the middle frame plate 42, the upper pulley bushing A43 is forced to shift laterally along the inclined trajectory of the guide groove, and then the two parallel handles 44 drive the baffle part 5 to change from the vertically stacked state to the unfolded state.

[0043] A rotating shaft 45 is also connected to the side of the handle 44. The rotating shaft 45 is arranged perpendicular to the handle 44. One end of the rotating shaft 45 is rotatably installed inside the fixed seat 46. The fixed seat 46 is a seat with a shaft hole and a rolling bearing is installed inside. The rotating shaft 45 passes through the inner hole of the bearing to achieve rotational engagement. The fixed seat 46 is fixed to the side of the upper baffle assembly 51 by bolts. This enables the swinging motion of the handle 44 to be transmitted to the upper baffle assembly 51, driving the upper baffle assembly 51 to maintain a vertical posture and complete the lifting action during the upward process.

[0044] The baffle section 5 is the core working surface for realizing the water-blocking function of the present invention. It includes an upper baffle assembly 51 and a lower baffle assembly 52. ​​The two are stacked and contacted in the working state. The left and right sides of the upper baffle assembly 51 are respectively connected to two fixed seats 46 by bolts. That is, the left fixed seat 46 is connected to the left side of the upper baffle assembly 51, and the right fixed seat 46 is connected to the right side of the upper baffle assembly 51, so as to synchronously transmit the power of the transmission part 4 to the left and right sides of the upper baffle assembly 51.

[0045] The lower baffle assembly 52 includes a pressure-bearing baffle 521, which is a single piece of high-strength stainless steel plate or aluminum alloy composite plate. Its thickness and strength are determined based on the designed water-blocking height. The left and right sides of the pressure-bearing baffle 521 are respectively wrapped with protective plates B522. The protective plates B522 are channel-shaped or angular metal plates, fixed to the edges of the pressure-bearing baffle 521 by bolts, to enhance the impact resistance and wear resistance of the edges of the pressure-bearing baffle 521. Two bearing shafts 523 protrude outwards from the upper and lower sides of the protective plates B522, meaning two bearing shafts 523 are provided on each side of the protective plate B522, for a total of two sets and four bearing shafts. Two sets of receiving shafts 523 are rotatably connected to two pulley bushings C49 respectively. One pulley bushing C49 is slidably installed in the vertical groove of the middle frame plate 42, and the other pulley bushing C49 is slidably installed in the vertical groove of the outer frame plate 41. The vertical grooves are all waist-shaped grooves extending in the vertical direction. The outer diameter of the pulley bushing C49 is clearance-fitted with the groove width of the vertical groove, allowing the pulley bushing C49 to slide freely up and down in the vertical groove without jamming. Through the above structure, the upper and lower ends of the lower baffle assembly 52 are constrained by the middle frame plate 42 and the outer frame plate 41 respectively, and always maintain a vertical posture during the baffle lifting process, avoiding the baffle tilting or shaking.

[0046] The working process of the device of the present invention is as follows: First, during the normal standby state during the flood season, the motor 32 does not work, the threaded slider 37 is located at the lowest end of the lead screw 36, the upper baffle assembly 51 and the lower baffle assembly 52 are stacked on top of each other, and the whole is located in the groove space formed between the two base plates 13 of the base 1. The upper surface of the baffle part 5, that is, the upper surface of the upper plate 514 of the upper baffle assembly 51, is flush with the upper end surface of the base plate 13 and the ground, so that vehicles and pedestrians can pass normally and the equipment is in a concealed standby state.

[0047] Secondly, when the water level monitoring unit detects that the water level has reached or exceeded the preset warning threshold, or when a water blocking command is manually issued through the on-site control module or remote control module, the control unit receives the start signal and controls the motor 32 to start running in the forward direction. The output shaft of the motor 32 drives the drive wheel 33 to rotate. The drive wheel 33 transmits power to the driven wheel 35 through the connecting belt 34. The driven wheel 35 drives the lead screw 36 to rotate in the forward direction around its own axis. Since the threaded slider 37 is threadedly engaged with the lead screw 36 and its circumferential rotation is restricted by the guide rail, the forward rotation of the lead screw 36 drives the threaded slider 37 to move upward linearly along the lead screw 36.

[0048] Secondly, the threaded slider 37 drives the outer frame plate 41, which is fixed to it, to rise synchronously. The outer frame plate 41 drives the middle frame plate 42 to rise together through the support plate and bolts. During this process, the rise of the middle frame plate 42 causes the two pulley bushings A43 in the guide groove to slide along the guide groove track. Since the upper part of the guide groove is inclined, the pulley bushing A43 located above is forced to move laterally inward when it rises to the inclined section. This lateral displacement is driven by the parallel four-bar linkage of the upper handle 44 and the lower handle 44, which drives the fixed seat 46 and... The upper baffle assembly 51, which is fixedly connected to it, remains vertical as it rises. At the same time, the lower baffle assembly 52 slides and rises in the vertical grooves of the outer frame plate 41 and the middle frame plate 42 through the receiving shaft 523 and the pulley bushing C49, respectively. When the upper pulley bushing A43 slides to the end of the inclined section of the guide groove, the upper baffle assembly 51 and the lower baffle assembly 52 gradually change from the initial overlapping state to the vertical side-by-side state. That is, the two baffles merge in the horizontal direction and together form a complete water barrier perpendicular to the ground.

[0049] Then, when the baffle section 5 rises to the preset height, the control unit controls the motor 32 to stop operating. At this time, the lead screw 36 stops rotating, the threaded slider 37 is locked at the height position, and the rubber strip A513 at the bottom of the upper baffle assembly 51 is fitted and pressed into the mating groove at the top of the pressure baffle 521, forming the first seal. The rubber strip B524 at the bottom of the pressure baffle 521 is tightly abutted against the upper surface of the base plate 13, forming the second seal. At the same time, the sealing strips between the two sides of the baffle section 5 and the column cover 21 are compressed and adhered, and the sealing strip between the bottom of the baffle section 5 and the base plate 13 is also compressed and adhered, forming the third and fourth seals, effectively blocking water flow from seeping through the gaps between the baffles, between the baffle and the column cover 21, and between the baffle and the base plate 13, forming a complete, continuous, and reliable vertical water barrier.

[0050] Finally, once the danger has passed and the water level has fallen below the safe level, the control unit controls the motor 32 to run in reverse. The motor 32 drives the lead screw 36 to rotate in reverse, and the threaded slider 37 drives the outer frame plate 41 and the middle frame plate 42 to descend as a whole. During this process, each moving part moves in the completely opposite order to the rising process: the handle 44 rotates in reverse, the upper baffle assembly 51 and the lower baffle assembly 52 gradually return from a side-by-side state to a parallel overlapping state, and the whole thing descends back into the groove of the base 1. The upper surface of the baffle part 5 returns to being flush with the upper surface of the base plate 13 and the ground, the equipment returns to its initial concealed standby state, and the passage resumes normal passage.

[0051] Example 2: To further explain in detail the linkage and unfolding mechanism of the transmission part 4 and the baffle part 5 of the present invention, this embodiment focuses on describing the process of the baffle from the stacked state to the unfolded state.

[0052] Please continue reading. Figures 1 to 10 When the first stroke of the baffle 5 is raised, that is, the initial stage of rising from the lowest position, the motor 32 drives the lead screw 36 to rotate in the forward direction, and the threaded slider 37 drives the outer frame plate 41 and the middle frame plate 42 to rise synchronously. At this time, the two pulley bushings A43 slide upward in the guide groove of the middle frame plate 42. Since the lower part of the guide groove is a vertical section, the two pulley bushings A43 only rise in the vertical direction in the initial stage and do not produce lateral displacement. Therefore, the upper and lower handles 44 remain parallel and do not swing. At this time, the upper baffle assembly 51 and the lower baffle assembly 52 rise as a whole in the vertical direction, and the two remain in an overlapping state. This stage is the first stage of rising.

[0053] When the pulley bushing A43 slides upward to the starting position of the inclined section of the guide groove, as the outer frame plate 41 and the middle frame plate 42 continue to rise, one of the pulley bushings A43 is forced to slide along the inclined section trajectory, thereby generating a lateral displacement toward the fixed seat 46. This lateral displacement is transmitted through two parallel handles 44. The upper handle 44 rotates around the pivot 45 due to the lateral displacement of its upper pulley bushing A43, while the lower handle 44 rotates synchronously under the constraint of the parallel four-bar linkage. The two handles 44 always remain parallel, thus converting the lateral displacement of the pulley bushing A43 into a horizontal outward pushing motion of the fixed seat 46. The fixed seat 46 is fixedly connected to the side of the upper baffle assembly 51, so the upper baffle assembly 51 is pushed horizontally outward, i.e., away from the lower baffle assembly 52, so that the upper baffle assembly 51, which was originally located directly above the lower baffle assembly 52, gradually shifts away from the lower baffle assembly 52 in the vertical direction.

[0054] Meanwhile, the pressure-bearing baffle 521 of the lower baffle assembly 52 slides in contact with the vertical grooves of the outer frame plate 41 and the middle frame plate 42 via the bearing shaft 523 and the pulley bushing C49, respectively. There are two sets of four bearing shafts 523, located on the protective plates B522 on the left and right sides of the pressure-bearing baffle 521. One set of bearing shafts 523 slides in contact with the vertical groove of the outer frame plate 41 via the pulley bushing C49, and the other set of bearing shafts 523 slides in contact with the vertical groove of the middle frame plate 42 via another pulley bushing C49. Since the outer frame plate 41 and the middle frame plate 42 rise synchronously and the horizontal distance between them is... Since the distance remains constant, the lower baffle assembly 52 is simultaneously constrained by the two vertical grooves during its ascent, and can only rise vertically without any horizontal deviation, thus maintaining its stable vertical posture. When the upper pulley bushing A43 slides to the end position of the inclined section of the guide groove, the upper baffle assembly 51 and the lower baffle assembly 52 are completely offset and arranged vertically side by side. That is, the outer surface of the upper baffle assembly 51 and the outer surface of the lower baffle assembly 52 are located in the same vertical plane, and the two together form a complete water-blocking surface. At this time, the two baffle assemblies continue to rise synchronously until the preset water-blocking height is reached.

[0055] Through the coordinated operation of the parallel four-bar linkage of the transmission part 4 and the inclined section of the guide groove, the present invention achieves the simultaneous driving of the baffle lifting and the relative lateral movement between the two baffle sections by a single power source, namely a motor, without the need for additional independent driving or locking devices, which greatly simplifies the overall structure, reduces manufacturing costs and maintenance difficulty. At the same time, since the two handles 44 are arranged in parallel and of equal length, the fixed seat 46 maintains a constant posture during the movement, that is, it does not rotate, thereby ensuring that the upper baffle assembly 51 remains vertical during the lifting and unfolding process.

[0056] Example 3: This embodiment focuses on describing the collaborative working method of the control unit, water level monitoring unit, on-site control module, and remote control module in this invention.

[0057] The control unit is the core control hub of this invention, and it is located inside the column cover 21 or in a waterproof control box installed above the ground. Preferably, the control unit adopts a programmable logic controller (PLC) or an embedded microprocessor, which has preset water level threshold parameters and action logic programs. The power supply of the control unit is connected to the mains power, and the control unit is also equipped with an uninterruptible power supply (UPS) or a backup battery to ensure that at least one complete lifting and lowering action can still be completed in the event of a sudden power outage, so as to avoid the baffle from failing to rise or reset due to power failure.

[0058] The water level monitoring unit and the control unit are connected via wired signal cables or wireless communication modules. The water level monitoring unit preferably uses a submersible hydrostatic level transmitter or an ultrasonic level sensor, installed in a sump, storm drain grate, or storm drain pipe outside the channel inlet to monitor water level data in real time. This water level monitoring unit continuously collects water level data at a set sampling frequency, such as once per second, and sends the data to the control unit for processing in real time. The control unit is equipped with a water level comparator that compares the received real-time water level value with pre-stored warning thresholds, such as 50mm above ground level and alert thresholds, such as 100mm above ground level.

[0059] When the control unit determines that the real-time water level has reached or exceeded the warning threshold, the control unit automatically starts the motor 32, driving the baffle 5 to rise and block the water. The control unit first sends a closing signal to the start relay of the motor 32, and the motor 32 starts to rotate forward. At the same time, the timer inside the control unit starts to monitor the running time of the motor 32. When the baffle 5 rises to the preset height, the stroke detection device inside the control unit sends a positioning signal. This stroke detection device can be a rotary encoder installed at the top or bottom of the lead screw 36 to detect the number of rotations of the lead screw 36 and convert it into the linear displacement of the threaded slider 37; or it can be a photoelectric sensor or proximity switch installed on the inner wall of the column cover 21 to directly detect whether the threaded slider 37 has reached the predetermined position. The control unit then controls the motor 32 to stop and activates the brake to lock the lead screw 36, preventing the baffle from automatically falling back under gravity or water pressure. When the water level continues to rise and reaches the warning threshold, the control unit can issue a higher priority alarm signal, using a buzzer and warning light for audible and visual alarm, and sending emergency alarm information to the management center through the communication module.

[0060] When the water level monitoring unit detects that the water level has fallen back to a safe value, such as below the warning threshold for more than 30 seconds, the control unit determines that the danger has been eliminated, issues a reset command, controls the motor 32 to rotate in reverse, drives the baffle part 5 to descend and fold into the base 1, restoring the ground to a flat state. To ensure safety, before issuing the reset command, the control unit will use an infrared detection device or a geomagnetic induction device to detect whether there are people or vehicles around the baffle. If an obstacle is detected, the reset action will be paused and an alarm will be issued. The descent and reset will continue after the obstacle is removed.

[0061] In addition, the control unit also responds to manually triggered control commands. Commands sent by the field control module or remote control module start the motor 32 to perform water-blocking and raising actions or reset and lowering actions. The field control module includes a waterproof button panel or touch screen set on the outer wall of the column cover 21, which is equipped with three operation buttons: an up button, a down button, and an emergency stop button. After the operator presses the up button, the control unit performs an automatic raising action according to a preset program; after pressing the down button, the control unit performs an automatic lowering and reset action; the emergency stop button is used to immediately stop the operation of the motor 32 in an emergency. The remote control module includes a wireless communication unit, preferably a 4G or 5G cellular network module, a LoRa long-distance communication module, or an NB-IoT narrowband Internet of Things module, and a handheld remote control terminal or host computer management software. Authorized personnel can send remote commands to the control unit through a mobile APP, computer client, or dedicated remote control to achieve remote control in unattended situations.

[0062] Since this invention is an online device, it requires no manual assembly or disassembly, and the baffle part 5 is flush with the ground when it is lowered and folded, so it does not affect the passage of vehicles and pedestrians. In normal non-flood season conditions, the device always remains in standby mode without any manual intervention. Even in the event of sudden rainstorms and rapid rise in water level, the water level monitoring unit can sense the water level change in real time and automatically start the baffle to rise within seconds. The response speed is far superior to the traditional method of manually moving sandbags or inserting boards, which greatly improves the timeliness and reliability of flood control response.

[0063] Example 4: This embodiment focuses on illustrating the arrangement and working principle of the multiple sealing structures in this invention.

[0064] Please continue reading. Figures 1 to 10 As mentioned above, after the baffle portion 5 of the present invention is raised to the water-blocking position, a reliable sealing structure is needed to prevent water from seeping through the gaps between the components. To this end, the present invention provides sealing structures at several key connection positions, as follows: The first seal: the butt seal between the raising baffle 511 and the pressure-bearing baffle 521. A rubber strip A513 is fixedly connected to the bottom end of the raising baffle 511. This rubber strip A513 is an elastic sealing strip with an inverted trapezoidal or triangular cross-section, made of EPDM or CR rubber, possessing good aging resistance, ozone resistance, and water resistance. The top of the pressure-bearing baffle 521 has a butt groove adapted to the shape of the rubber strip A513. The cross-section of this butt groove is complementary to the cross-section of the rubber strip A513, such as a trapezoidal groove, V-shaped groove, or semi-circular groove. When the baffle part 5... After fully rising to the preset height, the rubber strip A513 at the bottom of the raising baffle 511, under the weight of the raising baffle 511 and the gravity of the upper baffle assembly 51, is fitted and pressed into the mating groove at the top of the pressure-bearing baffle 521. The rubber strip A513 is compressed and deformed, filling all the gaps in the mating groove, achieving a complete seal at the joint between the raising baffle 511 and the pressure-bearing baffle 521. The design of this mating groove ensures that even under water pressure, the rubber strip A513 will not come out of the mating groove, and the greater the water pressure, the tighter the fit between the rubber strip A513 and the mating groove, and the better the sealing effect.

[0065] The second seal is between the bottom of the pressure baffle 521 and the upper surface of the base plate 13. A rubber strip B524 is fixedly connected to the bottom of the pressure baffle 521. The rubber strip B524 is also made of EPDM material, and its lower end face is a smooth plane or has an arc-shaped sealing lip. When the baffle is fully raised to the water-blocking position, the lower surface of the rubber strip B524 abuts tightly against the upper surface of the base plate 13. Under the weight of the pressure baffle 521 and the water pressure above, a certain amount of compression deformation occurs, sealing the gap between the bottom of the pressure baffle 521 and the base plate 13, preventing water from seeping in from the bottom.

[0066] The third seal: the seal between the baffle part 5 and the column cover 21. A sealing strip is fixedly installed on the inner wall of the strip groove on the inner side of the column cover 21 along the entire height of the strip groove. The sealing strip is an elastic sealing profile with a cavity or lip. When the baffle part 5 rises or falls in the strip groove, the side of the baffle part 5 slides into contact with the lip of the sealing strip. Under the action of elastic force, the lip of the sealing strip is pressed tightly against the side of the baffle to form a sliding seal. When the baffle is fully raised and stops moving, the sealing strip is further compressed, and the sealing performance is further improved.

[0067] The fourth seal: the seal between the bottom of the baffle portion 5 and the base plate 13. On the upper surface of the base plate 13, on both sides of the lifting trajectory of the baffle portion 5, a horizontal sealing strip is fixedly installed. When the baffle portion 5 is raised, the upper surface of the sealing strip is tightly fitted to the bottom end face of the baffle portion 5, that is, the bottom end of the pressure baffle 521 and the bottom end of the raising baffle 511, sealing the horizontal gap between the bottom of the baffle and the base plate 13.

[0068] Through the coordinated operation of the four sealing structures, when the motor 32 drives the baffle part 5 to rise, the possible water seepage paths in the five directions of the front, back, left, right and bottom of the baffle are effectively blocked by the sealing strips and rubber strips, thereby preventing water from seeping through the gaps and forming a complete vertical water barrier.

[0069] Example 5: This embodiment focuses on illustrating the pre-embedded installation method of the base 1 and the assembly relationship between the various components.

[0070] Please continue reading. Figures 1 to 10 During the installation process, a foundation pit is first excavated at the designated installation location of the passage. The size of the foundation pit should be larger than the overall dimensions of the base 1. The base 1 is then hoisted into the foundation pit, and its levelness and height are adjusted to ensure that the upper surfaces of the two base plates 13 are aligned with the designed ground elevation of the passage. Next, concrete is poured around the side supports 11 and reinforcing ribs 12 of the base 1. After the concrete has cured to its designed strength, the base 1 is firmly anchored in the ground, capable of withstanding the impact of water flow and lateral water pressure after the baffle is raised.

[0071] After the base 1 is installed and fixed, the column covers 21 are hoisted to the upper sides of the two base plates 13 respectively, and the bottom ends of the column covers 21 are fixedly connected to the base plates 13 with anchor bolts. Subsequently, four support columns 22 are installed at the four corners of the inner wall of the column cover 21. The lower ends of the support columns 22 are fixed to the base plates 13 with bolts, and the upper ends of the support columns 22 are fixed to the top plate 23 with bolts. In addition to connecting and supporting the top plate 23, the support columns 22 also enhance the overall structural rigidity of the column cover 21 and prevent the column cover 21 from deforming under lateral water pressure.

[0072] The installation sequence of the drive unit 3 is as follows: First, fix the fixing plate 31 on the upper end face of the top plate 23. Then, install the motor 32 below the fixing plate 31. The shaft end of the motor 32 extends upward through the top plate 23 and the fixing plate 31. Install the drive wheel 33. The lead screw 36 passes through the top plate 23 from top to bottom. Its upper and lower ends are rotatably installed on the bottom end of the top plate 23 and the bottom end of the inner wall of the column cover 21 through bearing seats, respectively. Then, install the driven wheel 35 on the upper end of the lead screw 36. Finally, install the connecting belt 34 to drive the drive wheel 33 and the driven wheel 35. The threaded slider 37 is pre-screwed onto the thread of the lead screw 36 during the installation process.

[0073] The assembly relationship of the transmission part 4 is as follows: the outer frame plate 41 is fixedly connected to the threaded slider 37, the middle frame plate 42 is fixed to the surface of the outer frame plate 41 by a support plate and bolts, and the inner frame plate 47 is also fixedly installed on the surface of the outer frame plate 41 and located inside the middle frame plate 42. Two pulley bushings A43 are installed in the guide groove of the middle frame plate 42, and two pulley bushings B48 are installed in the slide groove of the inner frame plate 47. The two ends of the handle 44 are respectively connected to the pulley bushings A43 and B48, and the rotating shaft 45 on the side of the handle 44 is installed in the fixed seat 46.

[0074] The assembly relationship of the baffle part 5 is as follows: the left and right sides of the raising baffle 511 of the upper baffle assembly 51 are fastened with protective plates A512 by bolts. The top of the raising baffle 511 is connected to the upper plate 514, and the bottom is connected to the rubber strip A513. The left and right sides of the pressure baffle 521 of the lower baffle assembly 52 are wrapped with the mating protective plates B522. The sides of the protective plates B522 are connected to the receiving shaft 523, and the bottom of the pressure baffle 521 is connected to the rubber strip B524. The side of the upper baffle assembly 51 is mated and fixed to the fixed seat 46. The lower baffle assembly 52 slides with the vertical groove of the outer frame plate 41 and the vertical groove of the middle frame plate 42 through the receiving shaft 523 and the pulley bushing C49, respectively.

[0075] Finally, a sealing strip is installed between the base plate 13 and the baffle 5, and a sealing strip is also installed between the baffle 5 and the column cover 21. The installation positions of all sealing strips should ensure that they can be evenly compressed after the baffle is raised, so as to avoid local sealing failure due to installation deviation.

[0076] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
