Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically a real-time monitoring device that can cope with different harsh environments. Background Technology

[0002] my country has a dense network of rivers and a long coastline. Dikes, as the core infrastructure of flood control projects, play a crucial role in resisting floods, protecting the lives and property of residents along the river, and ensuring the stable development of the regional economy. In recent years, with the increasing frequency of extreme weather events, the suddenness and destructiveness of flood disasters have significantly increased, placing higher demands on the real-time monitoring of dike operation and early warning of potential hazards. To promptly detect potential dangers such as seepage, piping, and dike breaches, the industry has gradually promoted the application of integrated monitoring devices. Through technologies such as image acquisition, environmental sensing, and data transmission, dynamic monitoring of the dikes and their surrounding hydrological environment can be achieved.

[0003] For example, Chinese patent CN222283366U discloses a dike seepage monitoring and early warning device. This device uses a column to mount a camera, ultrasonic level gauge, and piezometer, along with a protective cover and a scraper-type cleaning component, to initially achieve dike condition monitoring and lens protection. The camera is housed in a transparent protective cover fixed to the column. A motor-driven connector rotates the scraper to clean the surface of the protective cover. A solar panel and battery form the power supply system, ensuring continuous operation. This device, to a certain extent, solves the problem of reduced image clarity caused by dust, rain, and snow contamination in traditional monitoring equipment, providing fundamental technical support for dike seepage monitoring.

[0004] However, in actual flood control engineering applications, the above-mentioned technical solutions still have some shortcomings and are difficult to meet the monitoring requirements of high precision and high stability in complex environments, as follows: 1. The device uses a motor-driven connector to rotate the scraper blade, which rotates around the protective cover to clean pollutants such as mud, sand, and snow accumulation on the surface of the protective cover. However, the cleaning component is not linked to environmental monitoring data and cannot automatically adjust the cleaning intensity and frequency according to the actual pollution conditions such as rain, snow, dust, and flying sand. This leads to a contradiction between excessive cleaning and energy consumption or pollution accumulation that is not cleaned in time, making it difficult to adapt to the variable weather conditions in flood control scenarios.

[0005] 2. The protective cover of this device is a fixed installation structure, always covering the camera. In clear weather or when there are no pollutants, the protective cover can provide basic protection, but the optical loss of the transparent material (even with high light transmittance) will still affect the camera's shooting accuracy to some extent, especially in low-light environments, which can easily lead to blurred image details and affect the identification of subtle hidden dangers such as cracks in the dike and seepage traces. At the same time, the fixed protective cover cannot be adjusted according to monitoring needs. When maintenance and repair of the camera are required, the entire protective cover must be removed, which is cumbersome and can easily damage components, reducing the convenience of device operation and maintenance. Utility Model Content

[0006] The purpose of this invention is to provide a real-time monitoring device that can cope with different harsh environments, in order to solve the problems mentioned in the prior art in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a real-time monitoring device capable of handling various harsh environments, comprising a column, a radar flow meter mounted on one side of the column via a crossbar, a camera mounted on one side of the column via an L-shaped mounting plate, a transparent protective cover mounted on the mounting plate, and a cleaning mechanism mounted on the mounting plate and acting on the protective cover. The protective cover is vertically slidably connected to the vertical section of the mounting plate. The cleaning mechanism includes a scraper and a drive assembly. The scraper is vertically slidably connected to the vertical section of the mounting plate and located outside the protective cover. The inner wall of the scraper is adapted to the outer wall of the protective cover. The drive assembly is mounted on the column and is drively connected to the protective cover and the scraper, used to drive the protective cover to move vertically and the scraper to move reciprocally vertically.

[0008] Furthermore, the drive assembly includes a motor vertically mounted on one side of the column via a motor mount, a drive shaft connected to the motor output shaft, a screw connected to the bottom end of the drive shaft, an electromagnetic clutch located at the connection between the drive shaft and the screw, and a drive rod rotatably connected between the motor mount and the horizontal section of the mounting plate; the screw is threadedly connected to the upper part of the protective cover, the outer wall of the electromagnetic clutch is fixed to the column, the bottom end of the drive rod is a reciprocating screw, the scraper strip is provided with a threaded seat, the reciprocating screw is adapted to and threadedly connected to the threaded seat, and the upper ends of the drive shaft and the drive rod are both provided with sprockets, and the two sprockets are connected by chain drive.

[0009] Furthermore, a micro switch is provided on the horizontal section of the mounting plate, and a pressure plate is provided inside the protective cover, with the pressure plate located directly above the micro switch.

[0010] Furthermore, a rain and snow sensor, a rainfall sensor, and a wind speed sensor are connected to the upper end of the column via a horizontal plate.

[0011] Further, a waterproof distribution box is arranged on the other side of the upright column, a remote control terminal is built in the waterproof distribution box, and the remote control terminal is electrically connected with the radar current meter, the camera, the motor, the electromagnetic clutch, the micro switch, the rain and snow sensor, the rainfall sensor and the wind speed sensor.

[0012] Further, a solar panel is also arranged on the other side of the upright column.

[0013] Further, a mounting base is arranged at the bottom of the upright column.

[0014] Further, the horizontal section of the mounting plate is made of a transparent material.

[0015] Aiming at the defects of the prior art, the utility model has the following specific benefits through structural optimization and function innovation: 1. The device innovatively adopts a vertically sliding scraping strip design. The inner wall of the scraping strip is adapted to the outer wall of the protective cover, and the driving assembly drives the scraping strip to reciprocate vertically along the protective cover, which can fully cover and wipe the surface of the protective cover, especially can effectively remove stubborn sediment, rain and snow deposits attached to the vertical area of the protective cover, improve the cleaning efficiency, ensure the overall cleanliness of the surface of the protective cover, and ensure that the shooting field of view of the camera is unobstructed.

[0016] 2. The device combines the cleaning mechanism with the rain and snow sensor, the rainfall sensor and the wind speed sensor. When the sensors monitor rainy and snowy weather or the rainfall is greater than 5mm / h, or sand and stones are blown by wind, the remote control terminal automatically starts the cleaning process; when the environment returns to normal, it automatically stops cleaning and resets. This linkage control mode avoids the contradiction between excessive cleaning energy consumption and unremoved accumulated pollution, can dynamically adjust the cleaning strategy according to the changeable meteorological conditions in flood control scenarios, adapt to the cleaning requirements of different pollution degrees, and improve the adaptability and energy saving performance of the device in complex environments.

[0017] 3. The device innovatively adopts a vertical sliding structure for the protective cover. In sunny weather or when no pollutants are attached, the protective cover can be lifted to a non-working position through the driving assembly, completely avoiding the shooting field of view of the camera, thoroughly eliminating the interference of the optical loss of the transparent material on image acquisition, ensuring that the camera can clearly capture subtle hidden dangers such as dike cracks and seepage traces, and significantly improving the monitoring accuracy in special environments such as low light; only in protection scenarios such as rain and snow, the protective cover is controlled to move down to cover the camera, so as to realize on-demand protection.

[0018] 4. The protective cover of the device is slidably connected with the mounting plate through a sliding rail, and can automatically realize lifting relying on the driving assembly, so that the camera can be exposed without manual disassembly. During maintenance, operation and maintenance personnel only need to control the protective cover to rise through the remote control terminal, so as to directly maintain the camera, which greatly simplifies the operation process, reduces the disassembly loss of components, and improves the operation and maintenance convenience and service life of the device.

[0021] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. As shown in Figures 1-3, this utility model discloses a real-time monitoring device capable of handling various harsh environments, comprising a basic support component, an image monitoring component, a cleaning mechanism, an environmental monitoring component, and control and power supply components. It enables real-time monitoring of flow, images, and environmental parameters in flood control projects, while simultaneously solving the problem of cleaning the camera's protective cover and ensuring monitoring stability. Specific implementation methods are as follows: The basic support components are the core of the entire device, including column 1, crossbar 2, and mounting base 25. Column 1 is made of Q235 carbon steel with a wall thickness of 8mm. Its length is set to 3-5m according to monitoring requirements. The bottom is fully welded to mounting base 25. The welded parts are treated with double-layer anti-corrosion treatment of epoxy zinc-rich primer and chlorinated rubber topcoat. The primer thickness is ≥60μm and the topcoat thickness is ≥80μm, effectively isolating moisture and air and preventing corrosion at the weld. Mounting base 25 is made of 45# steel plate, with a square structure, a side length of 300mm, and a thickness of 15mm. There are 20mm diameter mounting holes at the four corners. The inner wall of the mounting holes is coated with anti-rust grease, and nitrile rubber waterproof sealing rings are installed at the joints between the expansion bolts and the mounting holes. M18 expansion bolts are used to pass through the mounting holes and fix it to the concrete base of the flood control embankment or monitoring point. It is necessary to ensure that the verticality deviation of column 1 is ≤0.5° and there is no shaking. The crossbar 2 is made of seamless 304 stainless steel. 304 stainless steel itself has excellent corrosion resistance, resisting the erosion of moisture and rainwater in flood control scenarios. It has a diameter of 50mm, a wall thickness of 5mm, and a length of 1.2-1.5m. It is fixed to the middle of one side of the column 1 by welding to maintain a horizontal position. The stability of the crossbar 2 can be further improved by welding connecting rods to the ends of the column and crossbar. The welded joints between the connecting rods and the column and crossbar are also treated with epoxy zinc-rich primer and chlorinated rubber topcoat for corrosion protection. A 100mm diameter, 10mm thick 304 stainless steel flange is welded to the end of the crossbar 2 furthest from the column 1. The flange is connected to the flange interface at the bottom of the radar flowmeter 3 by four sets of M10 stainless steel bolts. The bolt surfaces are hot-dip galvanized, and a 3mm thick water-resistant nitrile rubber gasket is installed between the flanges to ensure a waterproof seal at the flange connection, preventing rainwater from seeping in and damaging the internal components of the radar flowmeter. This ensures that the radar flowmeter 3's detection end is accurately oriented towards the water flow direction, guaranteeing accurate flow data acquisition.

[0022] The image monitoring component is responsible for acquiring clear images of the monitoring area and consists of an L-shaped mounting plate 4, a camera 5, a transparent protective cover 6, a micro switch 18, and a pressure plate 19. The L-shaped mounting plate 4 is divided into a horizontal section and a vertical section, both made of transparent polycarbonate material (light transmittance ≥92%). Polycarbonate material has good weather resistance and waterproof properties, and can resist rainwater erosion without additional anti-corrosion treatment. The horizontal section is 300mm long and 12mm thick, and the vertical section is 400mm high and 10mm thick. The two sections are integrally injection molded, and the injection joint is sealed with ultrasonic welding to prevent rainwater from seeping in. The horizontal section extends to the outside of the column 1; the vertical section is detachably connected to one side of the column 1 by four sets of M8 stainless steel bolts, and is on the same side as the crossbar 2. Fluororubber waterproof washers are added at the joints between the bolts and the mounting plate and column, and the bolt heads are covered with waterproof caps. Camera 5 is fixed to the side wall of the vertical section by three sets of M6 stainless steel bolts. The housing of camera 5 is made of aluminum alloy and is anodized with an oxide film thickness of ≥15μm. Waterproof glass lens is added to the camera lens, and the lens is sealed with a silicone rubber sealing ring, achieving a protection level of IP67. The housing of camera 5 is made of aluminum alloy, the lens faces the monitoring area, and the distance between the center of the lens and the lower surface of the horizontal section is 60mm to avoid the mounting plate obstructing the field of view. The transparent protective cover 6 is made of high-transmittance acrylic material. The acrylic material surface is sprayed with a nano-waterproof coating with a thickness of 5-8μm. It has hydrophobic and self-cleaning properties, which can reduce the residue of rainwater on the surface of the protective cover. The overall shape is a rectangular cover with an opening at the bottom and facing the vertical section of the mounting plate 4. It is 150mm long, 120mm wide, and 200mm high, with a wall thickness of 5mm. Vertical grooves (groove width 8mm, depth 5mm) are processed on the inner walls of both sides. They slide and engage with the polycarbonate slide rails (boss width 7mm, height 4mm) provided on the outer side of the vertical section of the mounting plate 4. Silicon-based grease is applied at the joint between the groove and the slide rail to ensure smooth sliding and form a sealing layer to prevent rainwater and mud from entering the joint gap. It can slide smoothly in the vertical direction and can completely cover the camera 5 to form protection. A 304 stainless steel pressure plate 19 is bonded to the bottom of the inner side of the protective cover 6. The 304 stainless steel material has good rust resistance and does not require additional anti-corrosion treatment. Correspondingly, a micro switch 18 (model KW12-3Z) is fixed to the upper surface of the horizontal section of the mounting plate 4 and directly below the pressure plate 19 by M4 stainless steel bolts. The micro switch 18 is covered with an ABS plastic waterproof shell. The waterproof shell is sealed to the mounting plate with double-sided tape to prevent rainwater from seeping in and damaging the internal components of the switch. When the protective cover 6 slides to the lowest position, the pressure plate 19 presses the micro switch 18 and triggers the position signal.

[0023] The cleaning mechanism is used to clean impurities on the outer wall of the protective cover 6 to ensure the clarity of the camera 5. It includes a scraper strip 7 and a drive assembly. The drive assembly consists of a motor base 8, a motor 9, a drive shaft 10, a screw 11, an electromagnetic clutch 12, a drive rod 13, a threaded seat 15, a sprocket 16, and a chain 17.

[0024] The motor mount 8 is a C-shaped bracket made of Q235 carbon steel. The surface of the bracket is hot-dip galvanized with a zinc layer thickness of ≥85μm to effectively prevent rust. It is vertically fixed to one side of the column 1 by four sets of M8 stainless steel bolts, located above the mounting plate 4. Fluororubber waterproof washers are added at the bolt mating points. The motor 9 (model 60SY-M00630) has an aluminum alloy shell with an electrophoretic coating treatment and a coating thickness of 20μm, providing waterproof and rustproof properties. It is installed on the motor mount 8 by M5 stainless steel bolts, with waterproof caps covering the bolt heads. A rubber dustproof sealing ring is added at the mating point between the motor output shaft and the coupling. The output shaft of the motor 9 faces downward and is connected to the drive shaft 10 through a steel elastic coupling. The coupling is covered with a polytetrafluoroethylene dustproof and waterproof cover, and the two ends of the cover are sealed to the drive shaft and motor output shaft by clamps. The drive shaft 10 is made of steel with a chrome-plated surface, the chrome layer thickness being ≥10μm to improve wear resistance and rust prevention. It has a diameter of 20mm and a length of 300mm, and is fitted with a PTFE dustproof sleeve. Both ends of the sleeve are secured with cable ties to prevent rainwater from seeping into the sleeve. The bottom end of the drive shaft 10 is connected to the driving end of the electromagnetic clutch 12 (model DLM0-2.5) via a key connection. The electromagnetic clutch 12 has a cast iron housing coated with high-temperature resistant rust-proof paint, the paint layer thickness being ≥50μm. The driven end is connected to the top of the screw 11 via a key connection. The outer wall of the electromagnetic clutch 12 is fixed to the outer wall of the column 1 via a connecting rod made of 304 stainless steel. Rubber waterproof gaskets are installed at the connection points with the clutch housing and the column. The screw 11 is a steel trapezoidal screw with a nitrided surface, the nitriding layer depth being 0.1-0. 0.2mm, improving hardness and rust resistance, 16mm in diameter, 250mm in length, 5mm in pitch. If the connection of screw 11 is unstable during use, its bottom end can be rotatably connected to the polycarbonate bearing seat provided on the upper surface of the horizontal section of the mounting plate 4 through a deep groove ball bearing (not shown in the figure). The bearing seat is filled with lithium-based grease, and a rubber sealing ring is installed on the outside of the bearing to prevent rainwater and mud from entering the bearing. Screw 11 is threaded into the internal threaded hole (matching trapezoidal thread) opened on the upper part of the protective cover 6. Rotation of screw 11 can drive the protective cover 6 to slide vertically. The drive rod 13 is made of steel with a chrome-plated surface. The chrome layer thickness is ≥10μm. It has a diameter of 18mm and a length of 350mm. The upper end is rotatably connected to the cast iron bearing seat on the lower surface of the motor seat 8 via a deep groove ball bearing. A waterproof sealing ring is installed at the connection between the bearing seat and the motor seat, and lithium-based grease is added inside the bearing. The lower end extends to below the horizontal section of the mounting plate 4, and the lower 200mm length is machined into a reciprocating screw 14 (4mm pitch, 180mm reciprocating stroke).The upper ends of the drive shaft 10 and the drive rod 13 are respectively connected and fixed with steel sprockets 16 (20 teeth, pitch 12.7mm) by keys. The surface of the sprockets is blackened and then sprayed with anti-rust oil. The chain 17 is made of stainless steel and is covered with a PVC dust cover. The two ends of the cover are sealed to the motor base and the mounting plate to prevent rainwater and mud from corroding the sprockets and the chain. The two sprockets 16 are at the same horizontal height and are connected by the stainless steel chain 17 to ensure that when the drive shaft 10 rotates, it drives the drive rod 13 to rotate synchronously.

[0025] Scraper strip 7 is an ABS plastic ring frame. ABS plastic has good weather resistance and water resistance, requiring no additional anti-corrosion treatment. It is 140mm long, 110mm wide, and 10mm thick, with a 5mm thick high-density sponge cleaning cotton (density 30kg / m³) pasted on the inside. 3 The cleaning cotton has microfibers planted on its surface to ensure a tight fit with the outer wall of the protective cover 6; a steel threaded seat 15 is welded to one side of the scraper 7, the surface of which is hot-dip galvanized, and the inner hole of the threaded seat 15 matches the thread of the reciprocating screw 14 and is threadedly connected to the reciprocating screw 14; at the same time, the two sides of the scraper 7 are slidably connected to the slide rail of the vertical section of the mounting plate 4 through polycarbonate sliders, which restricts the scraper 7 to move only vertically and ensures the stability of the cleaning process.

[0026] When the scraping strip 7 moves up and down, the electromagnetic clutch 12 is in a de-energized and disengaged state, the screw 11 is disconnected from the drive shaft 10, and the protective cover 6 remains stationary only through its threaded engagement with the screw 11. The self-locking characteristic of the trapezoidal thread (the helix angle is less than the equivalent friction angle) can effectively counteract the slight lateral force generated when the scraping strip 7 is cleaning, preventing the protective cover from sliding. Furthermore, the clearance between the protective cover 6 and the slide rail groove of the vertical section of the mounting plate 4 is only 1mm, and the silicone-based grease applied at the engagement point forms damping, further limiting the lateral displacement of the protective cover and preventing the protective cover from shaking or sliding due to the movement of the scraping strip.

[0027] The environmental monitoring and control system, along with the power supply components, works in tandem to automate the device's operation, ensuring continuous power supply and data transmission. It comprises a horizontal plate 20, a rain and snow sensor 21, a rainfall sensor 22, a wind speed sensor 26, a waterproof distribution box 23, and a solar panel 24. A carbon steel horizontal plate 20 is welded to the top of the column 1. The surface of the horizontal plate is treated with epoxy zinc-rich primer and polyurethane topcoat for corrosion protection and must be kept horizontal. The rain and snow sensor 21 (model YL-83), the rainfall sensor 22 (model JD-YL-6), and the wind speed sensor (model DS-FS01) all have ABS plastic housings. The sensor outlets are sealed with waterproof connectors, and rubber waterproof washers are added to the bolts connecting the sensors to the horizontal plate. They are fixed to the horizontal plate 20 with M6 stainless steel bolts, arranged in a triangular pattern to avoid mutual obstruction. The sensor signal output lines are introduced into the waterproof distribution box 23 through PVC conduits. The conduit interfaces are sealed with waterproof tape to prevent rainwater from seeping into the conduit and to protect the cables from environmental corrosion. At a height of 1.8m on the other side of column 1, a waterproof distribution box 23 is fixed by four sets of M8 stainless steel brackets. The brackets are made of 304 stainless steel. The outer shell of the waterproof distribution box 23 is made of fiberglass reinforced plastic (FRP). FRP has excellent waterproof and corrosion-resistant properties. A EPDM rubber sealing strip is installed between the distribution box door and the box body. The compression of the sealing strip is ≥3mm. The cable entry at the bottom of the box body is sealed with a waterproof gland. The protection level is IP67. The dimensions are 300mm×250mm×180mm. The internal remote control terminal is model STM32F103C8T6, and the circuit board material is FR-4. The epoxy glass cloth substrate, the 12V / 50Ah lead-acid battery pack, and the relay module housing are all made of ABS plastic. A waterproof and breathable membrane is pasted on the inside of the enclosure to prevent rainwater from entering and to balance the air pressure inside and outside the enclosure, thus avoiding condensation. The remote control terminal is electrically connected to the radar flow meter 3, camera 5, motor 9, electromagnetic clutch 12, micro switch 18, rain and snow sensor 21, rainfall sensor 22, and wind speed sensor 26 via copper core wires. The wire joints are wrapped with insulated waterproof heat shrink tubing, which completely covers the joints after shrinking to prevent short circuits and rainwater corrosion, thus enabling the control and data acquisition of each component.On one side of the support column 1, where the waterproof distribution box 23 is installed, the solar panel 24 is fixed by an adjustable aluminum alloy bracket (adjustment range 0-90°). The bracket surface is anodized. The solar panel 24 is made of monocrystalline silicon, and the frame of the panel is made of aluminum alloy and coated with anti-corrosion paint. The junction box adopts an IP65 waterproof design. The output line is connected to the wire through a waterproof connector. The power is 100W and the size is 1000mm×600mm. The output line is connected to the solar charge controller (model PWM-1210, shell is ABS plastic) inside the waterproof distribution box 23 through a waterproof connector. The connection between the charge controller and the wires inside the distribution box is also treated with insulated waterproof heat shrink tubing. The output end of the charge controller is connected to the battery pack to convert solar energy into electrical energy for storage, providing continuous power supply for the entire device and ensuring normal operation when there is no external power supply.

[0028] The working process of this utility model: When the weather is clear, after the device is powered on, the remote control terminal initializes all components. The radar flow meter 3 collects water flow velocity and water level data every 5 minutes and transmits it to the remote control terminal via an RS485 communication line. The camera 5 continuously captures images of the monitored area, and the video data is stored on the SD card of the remote control terminal. It can also be remotely uploaded to the monitoring center via a 4G module. At this time, the electromagnetic clutch 12 is engaged, the screw 11 is fixed to the drive shaft 10, and the protective cover 6 is raised to avoid obstructing the view of the camera 5.

[0029] In rainy, snowy, or windy weather, when the rain / snow sensor 21 detects a rain / snow signal, or the rain gauge 22 detects rainfall > 5 mm / h, or the wind speed ≥ 6 m / s, the remote control terminal initiates the cleaning process. The control motor 9 starts, driving the drive shaft 10 to rotate. At this time, the electromagnetic clutch 12 is engaged, driving the screw 11 to rotate, which in turn drives the drive rod 13 to rotate via the sprocket 16 and chain 17. The rotation of the screw 11 causes the protective cover 6 to move downwards. When it reaches the micro switch 18, the pressure plate 19 presses the micro switch 18, transmitting a signal to the remote control terminal, which then controls the electromagnetic clutch 12 to de-energize and disengage. At this time, the protective cover 6 covers the outside of the camera 5; the reciprocating screw 14 at the bottom of the drive rod 13 drives the scraper 7 to move vertically back and forth along the outer wall of the protective cover 6 through the threaded seat 15. The cleaning cotton wipes the impurities on the outer wall of the protective cover 6. The number of reciprocations is set to 3 times to clean rain, snow, mud and other debris on the protective cover. According to actual use needs, cleaning agent can be added and delivered to the surface of the protective cover 6 through the pump and nozzle.

[0030] When the rain and snow sensor 21, the rainfall sensor 22, and the wind speed sensor 26 detect that the environment has returned to normal for 30 minutes, the remote control terminal controls the electromagnetic clutch 12 to be energized and engaged, and controls the motor 9 to reverse. The screw 11 drives the protective cover 6 to move vertically upward to the initial state, and simultaneously drives the scraper 7 to move upward. Then the motor 9 stops, and the device returns to the normal monitoring state.
