Abstract
Description
Technical Field
[0001] This invention relates to the field of flood control and water barrier technology, and in particular to a lifting intelligent water barrier. Background Technology
[0002] Flood barriers are a crucial protective measure against urban flooding. Currently, due to limited surface space and urban beautification needs, many residential electrical substations are installed in basements. During the flood season, urban drainage systems often struggle to drain all rainwater, causing excessive runoff to seep into the ground, leading to basement leaks. Currently, flood barriers are typically deployed manually, a method that is inefficient, especially during nighttime flooding when workers struggle to reach the scene quickly. Furthermore, my country is actively promoting intelligent systems, rendering traditional manual flood barriers inadequate. In addition, coastal cities in my country are frequently hit by typhoons, making it difficult for operators to even leave their homes during severe weather.
[0003] Existing water-blocking technologies mainly include hydraulic and mechanical types, and each type has its own limitations in different application scenarios.
[0004] Patent application number CN202311527061.9 proposes a double-sided symmetrical lifting tunnel water-blocking device, which includes two supports arranged side by side, two water-blocking plates, and a retractable jacking mechanism. When encountering heavy rainfall, the retractable jacking mechanism is activated, the hydraulic cylinder drives the cylindrical support to rise, and the jacking rod rises accordingly, driving the two water-blocking plates to flip upward synchronously to form a ridge-shaped water-blocking structure. Compared with traditional water-blocking plates, it can resist greater impact force and makes the water-blocking plates have a buffering effect.
[0005] Patent application number CN202311182508.3 proposes a hydraulically driven lifting water-blocking device. The lifting water-blocking components include a water-blocking plate, a drainage channel, and a hydraulic column. Compared with traditional water-blocking plates, this device has the advantages of reasonable structure, convenient use, and stable and reliable operation.
[0006] Both of the above technologies use hydraulic drive to raise and lower the water baffle, which is expensive and prone to oil leakage, making maintenance difficult.
[0007] The patent application with application number CN202410311611.1 proposes a dual-position sliding intelligent water barrier, which includes a support plate, an upper water barrier, a lower water barrier and a power control system. Compared with traditional water barriers, this device can adjust the water barrier height according to the depth of water accumulation to achieve waterproofing at different water levels; however, this technology adopts a horizontally moving structure, which occupies a large amount of ground space.
[0008] The key to water-blocking device design lies in the installation of the seals. To achieve a completely watertight effect, the selection and installation location of the seals must be carefully considered. Furthermore, electrical distribution rooms are usually located in basements, making large-scale construction methods difficult. Therefore, smaller-scale construction methods should be used whenever possible. Summary of the Invention
[0009] In view of this, the purpose of this invention is to provide a lifting intelligent water baffle that is low in cost, has good safety performance, and can achieve precise and rapid lifting to flexibly respond to changes in different water levels, thereby improving water-blocking efficiency and convenience.
[0010] This invention is implemented using the following scheme: a lifting intelligent water baffle, comprising a ground surface and two walls standing on the ground surface, with a passage between the two walls. A box located below the passage is provided inside the ground surface. The box contains a liftable water baffle that can close the passage when raised. An electric drive mechanism for driving the water baffle to rise and fall is provided inside the box. The electric drive mechanism includes a motor and a vertically arranged ball screw. A screw nut that works in conjunction with the ball screw is connected to the lower part of the water baffle. The main shaft of the motor is connected to the ball screw via a synchronous belt and a synchronous pulley.
[0011] Furthermore, a vertically arranged optical axis is rotatably installed on the rear side of one of the walls. The lower end of the optical axis extends into the housing and is connected to the main shaft of the motor via a synchronous belt and a synchronous pulley. The upper end of the optical axis is connected to a handwheel.
[0012] Furthermore, a gear protective box is installed above the optical axis and mounted on the wall. The upper end of the optical axis extends into the gear protective box. An operation control box is fixedly installed on the front side of the wall corresponding to the position of the gear protective box. A handwheel shaft is provided through the wall between the gear protective box and the operation control box. The rear end of the handwheel shaft extends into the gear protective box. The gear protective box is provided with a first bevel gear connected to the upper end of the optical axis and a second bevel gear connected to the rear end of the handwheel shaft and meshing with the first bevel gear. The handwheel is located in the operation control box and connected to the front end of the handwheel shaft.
[0013] Furthermore, the operation control box is equipped with a power control system for controlling the operation of the motor and operation buttons, and the power control system is electrically connected to the motor.
[0014] Furthermore, it also includes a level sensor installed on the wall to detect the water level, the level sensor being electrically connected to the power control system.
[0015] Furthermore, the power control system is equipped with a communication module that can wirelessly connect to a mobile phone, and the joints of the power control system are equipped with rubber sealing rings that can withstand short-term water immersion.
[0016] Furthermore, a pair of positioning light rods distributed on both sides of the ball screw and parallel to the ball screw are connected inside the box, and a linear bearing that slides with the positioning light rods is connected to the lower part of the baffle plate.
[0017] Furthermore, a pair of guide rails located on both sides of the baffle plate are fixedly connected inside the box. The baffle plate is slidably connected between the two guide rails. The guide rails have a U-shaped cross section. The two guide rails extend upward through the box and the parts extending through the box are fixedly connected to the two side walls respectively. Rubber sealing strips are provided on both sides of the guide rail openings.
[0018] Furthermore, the housing is composed of a rear panel, a bottom panel, a front panel, a left panel, a right panel, and a top panel. The top panel is divided into a movable top panel in the middle and fixed top panels at both ends. The length of the movable top panel is greater than the width of the baffle. The movable top panel is hinged to the rear panel via a hinge. The baffle is attached to the front panel, and a sealing strip is provided at the joint between the upper edge of the front panel and the baffle.
[0019] Compared with the prior art, the present invention has the following beneficial effects: The lifting intelligent water barrier of the present invention has a lower cost and better safety performance than the traditional hydraulic drive method. The height of the water barrier can be precisely controlled according to the depth of water accumulation. The electric control enables the water barrier to rise and fall quickly when needed, so as to flexibly respond to changes in different water levels and realize rapid water blocking work when waterlogging occurs. It improves water blocking efficiency and convenience, increases work efficiency, and reduces the labor intensity of staff. While meeting the flood control needs of underground power distribution rooms of the power grid, it also ensures the safety of staff.

Detailed Implementation
[0023] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0025] like Figures 1-9As shown, a lifting intelligent water barrier includes a ground surface 4 and two walls 3 standing on the ground surface 4, with a passage between the two walls 3. A box is located below the passage inside the ground surface. The box contains a liftable water barrier 2 that can close the passage when raised. To improve the strength of the water barrier, I-beams are welded around its perimeter, and several transverse reinforcing steel bars are welded in the middle. An electric drive mechanism for driving the water barrier 2 to rise and fall is located inside the box. The electric drive mechanism includes a motor 310 and a vertically arranged ball screw 303. The motor is installed at a specified height inside the box to prevent it from burning out if water enters the box. A screw nut 311 that works in conjunction with the ball screw 303 is connected to the lower part of the water barrier 2. The screw nut 311 is connected to a screw nut seat 311 at the lower part of the water barrier 2 by bolts, and then the screw nut 311 is installed on the screw nut seat 311 and fixed with bolts. The motor's main shaft is connected to the ball screw via a synchronous belt and pulleys, specifically a first synchronous pulley 304, a first synchronous belt 305, and a second synchronous pulley 306. The first synchronous pulley 304 is mounted on the upper end of the ball screw 303, and the second synchronous pulley 306 is mounted on the motor's main shaft. The upper and lower ends of the ball screw are rotatably connected to bearing seats via bearings, and the bearing seats are fixed to the housing by bolts. The water baffle can be automatically raised and lowered by the motor. The automatic raising and lowering is precisely controlled by an operation button that controls the motor's operation. This electric control allows the water baffle to rise and fall quickly when needed, flexibly responding to changes in water level and enabling rapid water blocking during flooding, thus improving water blocking efficiency and convenience.
[0026] In this embodiment, a vertically arranged optical shaft 209 is rotatably mounted on the rear side of one side of the wall. The lower end of the optical shaft 209 extends into the housing and is connected to the main shaft of the motor via a synchronous belt and a synchronous pulley, namely a third synchronous pulley 307, a second synchronous belt 308, and a fourth synchronous pulley 309. The third synchronous pulley 307 is mounted on the main shaft of the motor, and the fourth synchronous pulley 309 is mounted on the lower end of the optical shaft 209. The upper end of the optical shaft is connected to a handwheel 203. Several bearing seats are installed on the wall for the optical shaft 209 to pass through. The optical shaft 209 is rotatably connected to the bearing seats via bearings 207 to achieve rotatable mounting of the optical shaft 209 on the wall. The bearing seats can be fixed to the wall using expansion bolts. In addition, this lifting intelligent water baffle also has a manual control function for lifting. When the motor fails to work normally for various reasons, the lifting of the water baffle can be controlled by operating the handwheel.
[0027] In this embodiment, a gear protective box 201 is installed on the wall above the optical axis 209. A protective box pad 202 is provided between the gear protective box 201 and the wall. The protective box pad 202 is fixed to the wall by expansion bolts. The gear protective box 201 is connected to the protective box pad 202 by screws. The upper end of the optical axis 209 extends into the gear protective box 201. A through hole is opened at the bottom of the gear protective box 201 for the upper end of the optical axis 209 to pass through. An operation control box 205 is fixedly installed on the front side of the wall corresponding to the position of the gear protective box. A handwheel shaft is provided through the wall between the gear protective box and the operation control box. The handwheel shaft is rotatably engaged with the wall. The specific installation method of the handwheel shaft is as follows: a hole is drilled in the wall, and then a sleeve is inserted into the hole. The handwheel shaft passes through the sleeve and its two ends are rotatably engaged with the sleeve through bearings. The rear end of the handwheel shaft extends into the gear protective box. The gear protective box and the protective box pad have through holes for the handwheel shaft to pass through. The gear protective box contains a first bevel gear 312 connected to the upper end of the optical shaft and a second bevel gear 313 connected to the rear end of the handwheel shaft and meshing with the first bevel gear. The handwheel 203 is located inside the operation control box and connected to the front end of the handwheel shaft. The rear side wall of the operation control box has through holes for the handwheel shaft to pass through. When the handwheel is rotated, the two meshing bevel gears drive the optical shaft to rotate. The rotation of the optical shaft then drives the ball screw to rotate via a synchronous belt and synchronous pulley, thereby raising and lowering the baffle plate.
[0028] In this embodiment, the operation control box 205 is equipped with a power control system for controlling the operation of the motor and operation buttons 204. The power control system is electrically connected to the motor. The operation control box is installed at the shoulder height of a normal adult on the wall. The operation buttons 204 are divided into three switches: up, down, and stop.
[0029] In this embodiment, a liquid level sensor installed on the wall is also included to detect the water level. The liquid level sensor is electrically connected to the power control system and can monitor changes in the water level in real time to automatically control the motor. When no personnel are needed, the raising and lowering of the baffle can be initiated simply by commands from the liquid level sensor, achieving full automation.
[0030] In this embodiment, the power control system is equipped with a communication module that can wirelessly connect to a mobile phone, allowing staff to remotely control the raising and lowering of the flood barrier using a mobile app. Even if the liquid level sensor fails, the raising and lowering of the flood barrier can be achieved by remotely controlling the motor's forward and reverse rotation via the mobile app. Furthermore, in extreme situations such as large-scale power outages in the city, manual operation of the handwheel to raise and lower the flood barrier is still possible. Considering the high humidity, water accumulation, and dusty environment in flood control scenarios, the power control system features rubber sealing rings at the joints and waterproof glands at the wiring ports, capable of withstanding short-term immersion and completely preventing external water from entering the enclosure and contacting electrical components.
[0031] In this embodiment, a pair of positioning light rods 301 are connected inside the box, distributed on both sides of the ball screw 303 and parallel to the ball screw. The two ends of the positioning light rods 301 are fixed to the fixed seats inside the box. The fixed seats are fixedly connected to the box by bolts. The lower part of the baffle is connected to a linear bearing that slides with the positioning light rods. The lower part of the baffle is connected to a bearing seat for installing the linear bearing by bolts. The positioning light rods are used to realize the stable lifting and lowering of the baffle.
[0032] In this embodiment, a pair of guide rails 210 are fixedly connected to the inside of the box, located on both sides of the baffle plate. The baffle plate is slidably connected between the two guide rails 210. The guide rails 210 have a U-shaped cross-section and are made of channel steel. The two guide rails 210 extend upwards through the box, and the portions extending through the box are respectively fixedly connected to the side walls. Rubber sealing strips 211 are provided on both sides of the guide rail openings to improve the waterproof effect and effectively prevent water from seeping into the interior, thus improving the sealing performance. The upper part of the guide rail 210 (i.e., the portion extending out of the box) is fixed to the wall with expansion screws to enhance the strength of the guide rail and ensure that the baffle plate can withstand the water pressure.
[0033] In this embodiment, the housing is formed by a rear panel 101, a bottom panel 102, a front panel 103, a left panel 104, a right panel 105, and a top panel 106. The top panel is divided into a movable top panel in the middle and fixed top panels at both ends. The length of the movable top panel is greater than the width of the baffle. The movable top panel is hinged to the rear panel via hinges. Under normal circumstances, the movable top panel is closed, which prevents dust and other impurities from entering the housing. When the baffle rises, the baffle automatically opens the movable top panel, which is tilted against the baffle when opened. When the baffle descends, the movable top panel automatically closes. The edges of the movable top panel are also equipped with sealing strips. When the movable top panel is closed, the sealing strips can more effectively prevent external dust and other impurities from entering the housing and affecting the raising and lowering of the baffle.
[0034] The baffle plate is fitted to the front panel, and a sealing strip is provided at the joint between the upper edge of the front panel and the baffle plate. The bottom panel, front panel, rear panel, left panel, right panel, and fixed top panel are connected vertically to each other by screws. The upper and lower ends of the positioning light rod are fixed to the rear panel by fixing seats, and the fixing seats are bolted to the rear panel. The motor is also fixed to the rear panel by bolts. The two ends of the ball screw are rotatably connected to bearing seats by bearings, and the bearing seats are bolted to the rear panel. The two guide rails are fixed to the left and right ends of the front panel by bolts or welding.
[0035] Compared to existing lifting baffles, this invention uses a combination of ball screw, synchronous belt, and motor for transmission. Compared to hydraulic drive, this equipment is cheaper and safer, eliminating the risk of oil leakage. Furthermore, the high precision of the ball screw allows for precise control of the lifting height. In addition, the numerous balls between the ball screw and nut create sliding friction, requiring less motor power to control costs while maintaining high efficiency.
[0036] How does this lifting intelligent water baffle work? When the liquid level sensor detects water seepage in the basement, the power control system activates a motor to raise the water-blocking baffle, which in turn automatically lifts the top panel. The baffle's height can be automatically adjusted based on the water level. When the liquid level sensor detects a drop to 2mm or below, the power control system reverses the motor, lowering the baffle and automatically closing the top panel, achieving a sealing and dustproof effect. In power distribution room applications, a liquid level of 2mm or below represents a small amount of water that can be quickly eliminated by natural air drying, posing no risk of further flooding. Lowering the baffle at this level prevents backflow of water. This threshold ensures that the baffle lowers only after the water has completely drained (or reached a harmless level), while avoiding prolonged periods of heightened baffle position due to waiting for the ground to dry completely, reducing mechanical wear and extending equipment lifespan. Furthermore, power grid personnel can monitor the power distribution room and promptly detect problems, using mobile software to control the motor's forward and reverse rotation to raise and lower the baffle.
