Description

Technical Field

[0001] The present invention belongs to the technical field of water environment management, and in particular relates to a monitoring and early warning device for water environment management. Background Art

[0002] With the rapid development of industrialization and urbanization, the water environment faces severe pollution challenges. Real-time monitoring and early warning of the water environment are crucial for timely detection and remediation measures. Traditional monitoring and early warning equipment often utilizes a top-mounted camera structure, which can only monitor the water surface and cannot monitor underwater. This makes it difficult to meet the demand for simultaneous monitoring both above and below the surface. Furthermore, over long-term operation, dust and water vapor easily adhere to the lenses of traditional detection and early warning equipment, causing contamination that affects image clarity. Statistics from an environmental protection agency show that the accumulation of contaminants on the mirror surface can reduce image clarity by over 40% within 72 hours, seriously affecting the accuracy of key indicators such as algae proliferation and oil spread. Existing cleaning solutions often rely on manual wiping, but maintenance cycles typically take 7-15 days. This labor cost significantly contributes to total operation and maintenance costs. Therefore, to address these issues, we have proposed a monitoring and early warning device for water environment management.

[0003] The approaches described in this section are not necessarily approaches that have been previously conceived or employed. Unless otherwise indicated, it should not be assumed that any approach described in this section is prior art simply by virtue of its inclusion in this section. Similarly, unless otherwise indicated, the issues raised in this section should not be considered as having been recognized in any prior art. Summary of the Invention

[0004] In order to overcome the problems existing in the related art, the present invention discloses a monitoring and early warning device for water environment management.

[0005] To achieve the above object, a technical solution adopted by the present invention is:

[0006] A monitoring and early warning device for water environment management includes a floating seat and a rotating monitor. The floating seat includes a float and a wiping cleaning piece. The float is provided with a first assembly groove running through the float from top to bottom. The wiping cleaning piece is arranged on the front wall of the first assembly groove. The rotating monitor includes a rotating disk, an annular transparent lens, a rotating driver and an image collector. The rotating disk is connected to the first assembly groove in a transverse rotation. The circumference of the rotating disk has a hollow groove. The image collector is assembled in the rotating disk and collects environmental images through the hollow groove. The annular transparent lens is arranged on the circumference of the rotating disk and closes the hollow groove and contacts the wiping cleaning piece. The rotating driver connects the float and the rotating disk to drive the rotating disk to rotate around its own axis.

[0007] Furthermore, the floating seat also includes a slider and a first elastic member. There are two sliders, and the two sliders are respectively connected to the left and right walls of the first assembly groove for sliding back and forth. The stator and rotor of the rotary driver are respectively connected to the rotating disk and one side of the slider, and the other side of the slider is rotatably connected to the other end of the rotating disk. The first elastic member is used to drive the slider to move forward.

[0008] Furthermore, the wiping cleaning member is detachably connected to the front wall of the first assembly groove.

[0009] Furthermore, the wiping cleaning piece includes a pad, a plug-in and a flexible wiping piece, the plug-in and the flexible wiping piece are respectively fixed to the front and rear ends of the pad, the front wall of the first assembly groove is provided with a plug-in slot for plugging the plug-in, and the wiping cleaning piece is plugged into the plug-in slot through the plug-in.

[0010] Furthermore, the rotation monitor also includes a guide wheel and a second elastic member. The guide wheel is eccentrically connected to the end face of the rotating disk. The second elastic member is used to drive the guide wheel to rotate clockwise. The outer side of the rotating disk has a limiting surface for limiting the rotation angle of the guide wheel. The limiting surface is located above the rotation axis of the rotating disk. When the guide wheel abuts against the limiting surface, the periphery of the guide wheel will radially extend out of the periphery of the rotating disk. When extending, if the protruding part of the periphery of the guide wheel is pushed from top to bottom, the guide wheel will overcome the elastic force of the second elastic member and rotate counterclockwise, so that the protruding part of the periphery of the guide wheel is retracted into the periphery of the rotating disk.

[0011] Furthermore, there are two groups of lifting components composed of the guide wheel and the second elastic member, and the two groups of lifting components are symmetrically arranged at the left and right ends of the rotating disk.

[0012] Furthermore, an accommodating groove for accommodating the guide wheel is provided on the end surface of the rotating disk, and the upper side wall of the accommodating groove is a limiting surface.

[0013] Furthermore, the guide wheel passes through the rotating shaft to the interior of the rotating disk, and the part of the rotating shaft located inside the rotating disk is clamped with a clamping spring through a clamping spring groove; the second elastic member is a torsion spring, which is sleeved on the outside of the rotating shaft, and the two torsion arms of the torsion spring are respectively clamped with the rotating shaft and the rotating disk.

[0014] Furthermore, the left and right walls of the first assembly groove are each provided with a second assembly groove, and the two sliders are respectively slidably assembled in the two second assembly grooves;

[0015] A third assembly groove is formed on the rear wall of the second assembly groove. The first elastic member is a coil spring which is assembled in the third assembly groove. Two ends of the coil spring respectively abut against the slider and the rear wall of the third assembly groove.

[0016] Furthermore, the floating seat further comprises a warning light, which is arranged on the top of the floating seat, and the rotation driver, image collector and warning light are all electrically connected to an external control device;

[0017] The external control device includes:

[0018] A drive control module, used for controlling the rotary driver to drive the rotary disk to perform rotational motion;

[0019] An image processing module is used to receive and analyze environmental image data collected by the image collector, and generate an early warning signal when it detects that the water pollution index exceeds a preset threshold;

[0020] The early warning execution module is used to respond to the early warning signal and synchronously perform the following operations: control the warning light to start the strobe alarm, pop up the pollution area information on the display screen of the monitoring terminal, and send an early warning text message containing the pollution area information to the preset management terminal through the wireless communication unit.

[0021] The present invention has at least the following beneficial effects:

[0022] Through the integrated design of the rotating monitor and the floating seat, full-view monitoring of the water surface and underwater is achieved. The self-cleaning structure extends the maintenance cycle and reduces labor costs. The elastic pressure component enhances the wiping force to ensure the lens cleaning effect. The detachable cleaning part design improves the convenience of maintenance. The automatic lifting component can form an operating space without manual contact, optimizing the maintenance experience. Intelligent early warning analyzes image data in real time, and multi-level linkage early warning improves pollution response efficiency, providing an efficient and intelligent technical solution for water environment management.

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] Reference Figure 1-Figure 5 As shown, the monitoring and early warning device for water environment management in this embodiment includes a floating seat 1 and a rotating monitor 2.

[0033] In this embodiment, the floating seat 1 includes a float 11 and a wiping cleaning member 12 .

[0034] The floating body 11 is provided with a first assembly groove 111 which passes through the floating body 11 from top to bottom. The first assembly groove 111 provides space for the installation and rotation of the rotary monitor 2 .

[0035] The wiping cleaning member 12 is provided on the front wall of the first assembly slot 111 and is used for wiping and cleaning the rotating monitor 2 .

[0036] In this embodiment, the rotation monitor 2 includes a rotating disk 21 , an annular transparent lens 22 , a rotation driver 23 and an image collector 24 .

[0037] The rotating disk 21 is laterally connected to the first mounting slot 111 and can rotate about its own axis. The rotating disk 21 has a hollowed-out slot on its periphery. The image collector 24 is mounted within the rotating disk 21 and captures environmental images through the slot. The slot enables the image collector 24 to capture image information of the aquatic environment. The image collector 24 can also be integrated with a fill light device to provide supplemental illumination to the monitored area in low-light conditions.

[0038] An annular transparent lens 22 is positioned around the rotating disk 21, enclosing the hollowed-out slot and contacting the wiping cleaning member 12. This protects the image collector 24 from water and impurities. Furthermore, as the rotating disk 21 rotates, it rubs against the wiping cleaning member 12, cleaning the surface of the annular transparent lens 22.

[0039] Rotary actuator 23 connects float 11 to rotating disk 21 and is used to drive rotating disk 21 to rotate about its own axis. Rotary actuator 23 can be a driving device such as a stepper motor. The rotation of the stepper motor drives rotating disk 21, thereby enabling rotation monitoring of image collector 24 and cleaning of annular transparent lens 22.

[0040] When monitoring the aquatic environment is required, the float base 1 is placed on the water surface, and the float 11 floats on the surface due to its own buoyancy. The float 11 is surrounded by multiple rope clips for connecting ropes to control its floating position. The rotary actuator 23 is activated, driving the rotating disk 21 to rotate about its own axis within the first assembly slot 111. As the rotating disk 21 rotates, the image collector 24 captures images of the surrounding aquatic environment through the hollow slot and the annular transparent lens 22. Due to the rotation of the rotating disk 21, the image collector 24 can be positioned above the float 11 to monitor the water surface or rotated below the float 11 to monitor the underwater environment. This allows a single device to simultaneously perform surface and underwater monitoring operations. Simultaneously, the annular transparent lens 22 rotates with the rotating disk 21, contacting and rubbing against the wiping cleaning element 12 located on the front wall of the first assembly slot 111. The wiping cleaning element 12 wipes away dust, algae, and other contaminants on the surface of the annular transparent lens 22, keeping the lens clean and ensuring image clarity. Since the rotating monitor 2 can achieve self-cleaning when rotating to switch the monitoring angle, the manual maintenance cycle can be greatly extended, which can greatly reduce the labor cost in the total operation and maintenance cost.

[0041] In order to improve the wiping strength of the wiping cleaning member 12 , the present embodiment further optimizes the structure of the floating seat 1 . Specifically, the floating seat 1 further includes a slider 14 and a first elastic member 13 .

[0042] There are two sliders 14 . The left and right walls of the first assembly groove 111 are both provided with second assembly grooves 113 . The two sliders 14 are respectively slidably assembled in the two second assembly grooves 113 to form a slidable support structure.

[0043] The stator and the rotor of the rotary driver 23 are respectively connected to the rotary disk 21 and one side slider 14 , and the other side slider 14 is rotatably connected to the other end of the rotary disk 21 .

[0044] A third assembly groove is defined on the rear wall of the second assembly groove 113 . The first elastic member 13 is a coil spring 131 . The coil spring 131 is assembled in the third assembly groove. Two ends of the coil spring 131 abut against the slider 14 and the rear wall of the third assembly groove respectively.

[0045] The coil spring 131 is used to drive the slider 14 forward, causing the rotating monitor 2 to apply pressure toward the wiping cleaning member 12. This increases the friction between the wiping cleaning member 12 and the annular transparent lens 22, ensuring a tight fit between the annular transparent lens 22 and the wiping cleaning member 12. Even if sticky contaminants (such as algae or colloidal impurities) adhere to the surface of the annular transparent lens 22, the elastic pressure structure can maintain constant pressure to enhance the wiping force, preventing the cleaning effect from being weakened due to long-term use.

[0046] To facilitate replacement of the wiping cleaning member 12, the wiping cleaning member 12 is detachably connected to the front wall of the first assembly slot 111. Specifically, the wiping cleaning member 12 includes a backing plate 121, an insert 122, and a flexible wiper 123. The insert 122 and the flexible wiper 123 are respectively fixed to the front and rear ends of the backing plate 121. The front wall of the first assembly slot 111 is provided with an insertion slot 112 for inserting the insert 122. The wiping cleaning member 12 is inserted into the insertion slot 112 via the insert 122.

[0047] When the wiping cleaning member 12 is in the installed state, the rotating monitor 2 will maintain contact with the flexible wiping member 123 under the elastic force of the first elastic member 13, so that the pad 121 maintains contact with the front wall of the first assembly groove 111, thereby limiting the plug-in 122 from falling out of the plug-in groove 112, and the wiping cleaning member 12 will maintain the installed state under the pushing action of the rotating monitor 2.

[0048] When the rotating monitor 2 needs to be replaced, the rotating monitor 2 is pushed backward to overcome the elastic force of the first elastic member 13, so that an operating space is formed between it and the front wall of the first assembly groove 111, so that the wiping cleaning member 12 can be removed, and then a new wiping cleaning member 12 can be installed. After the plug-in 122 of the new wiping cleaning member 12 is inserted into place, the rotating monitor 2 is reset so that it remains in contact with the wiping cleaning member 12 under the elastic force of the first elastic member 13, and the replacement operation is completed.

[0049] In order to automatically form an operating space between the rotary monitor 2 and the front wall of the first assembly groove 111 by controlling the rotation of the rotary monitor 2 , this embodiment further makes the following improvements. Specifically, the rotary monitor 2 further includes a guide wheel 25 and a second elastic member 26 .

[0050] The guide wheel 25 is eccentrically connected to the end face of the rotating disk 21, and the second elastic member 26 is used to drive the guide wheel 25 to rotate clockwise. The outer side of the rotating disk 21 has a limiting surface 211 for limiting the rotation angle of the guide wheel 25. The limiting surface 211 is located above the rotation axis of the rotating disk 21. When the guide wheel 25 abuts against the limiting surface 211, the periphery of the guide wheel 25 will radially extend out of the periphery of the rotating disk 21. When extending, if the protruding portion of the periphery of the guide wheel 25 is pushed from top to bottom, the guide wheel 25 will overcome the elastic force of the second elastic member 26 and rotate counterclockwise, so that the protruding portion of the periphery of the guide wheel 25 is retracted into the periphery of the rotating disk 21.

[0051] Based on the above structure, during normal monitoring operations, the surface and underwater monitoring viewing angles can be switched by controlling the rotating disk 21 to rotate clockwise. When the rotating disk 21 rotates clockwise, if the guide wheel 25 is below the float 11, the guide wheel 25 will abut against the lower end surface of the float 11 near the front of the first assembly groove 111. If the guide wheel 25 is above the float 11, the guide wheel 25 will abut against the upper end surface of the float 11 near the rear of the first assembly groove 111. In both positions, the guide wheel 25 will overcome the elastic force of the second elastic member 26 and rotate counterclockwise, achieving automatic retraction and giving way. In this state, the annular transparent lens 22 will maintain close contact with the wiping cleaning member 12. After the guide wheel 25 rotates through the first assembly groove 111 with the rotating disk 21, the guide wheel 25 will return to its original position clockwise under the elastic force of the second elastic member 26.

[0052] When the wiping cleaning member 12 needs to be replaced, the rotating disk 21 can be controlled to rotate counterclockwise when the guide wheel 25 is above the float 11. When the extended portion of the guide wheel 25 abuts against the upper end surface of the float 11 near the front of the first assembly groove 111, the guide wheel 25 cannot rotate due to the restriction of the limit surface 211. Therefore, the peripheral surface of the guide wheel 25 abuts against the upper edge of the front wall of the first assembly groove 111. Under the guidance of the peripheral surface, the guide wheel 25 gradually enters the first assembly groove 111, pushing the rotating disk 21 to overcome the elastic force of the second elastic member 26 and slide backward. In this way, an operating space is automatically formed between the rotating disk 21 and the wiping cleaning member 12. When the width of the operating space reaches the target width, the rotating disk 21 is controlled to stop rotating to keep the operating space unchanged. At this time, the replacement operation can be carried out. After the replacement is completed, the rotating disk 21 is controlled to rotate in any direction so that the guide wheel 25 can be reset after rotating past the first assembly groove 111. The operating space is automatically formed by rotating the rotary disk 21, and there is no need for manual direct contact with the rotating monitor 2, which can reduce the difficulty of maintenance and improve maintenance efficiency.

[0053] In this embodiment, there are two sets of lifting assemblies consisting of guide wheels 25 and second elastic members 26, and the two sets of lifting assemblies are symmetrically arranged at the left and right ends of the rotating disk 21. This arrangement can enhance structural stability, and the symmetrical double lifting ensures that the rotating disk 21 can move backward stably.

[0054] In this embodiment, the end surface of the rotating disk 21 is provided with a receiving groove 212 for receiving the guide wheel 25, and the upper side wall of the receiving groove 212 is a limiting surface 211. The integrated design of the receiving groove 212 can optimize space utilization while maintaining the limiting function.

[0055] In this embodiment, the guide wheel 25 passes through the rotating disk 21 through the rotating shaft 251, and the part of the rotating shaft 251 located inside the rotating disk 21 is engaged with the retaining spring 252 through the retaining spring groove, so that the guide wheel 25 and the rotating disk 21 can be rotatably connected.

[0056] In this embodiment, the second elastic member 26 is a torsion spring 261, which is sleeved on the outside of the rotating shaft 251. The two torsion arms of the torsion spring 261 are respectively engaged with the rotating shaft 251 and the rotating disk 21. The second elastic member 26 can provide a stable elastic force for the rotating disk 21 to return to its original position.

[0057] In this embodiment, the floating seat 1 further includes a warning light 15 , which is provided on the top of the floating seat 1 and serves as an on-site early warning execution unit.

[0058] The rotary driver 23, the image collector 24 and the warning light 15 are all electrically connected to the external control device through waterproof cables, forming a complete monitoring and early warning closed loop.

[0059] The external control device adopts a modular design and includes the following core functional units:

[0060] The drive control module, which is based on a programmable logic controller (PLC) or a microprocessor (such as STM32), accurately controls the speed and direction of the rotary driver 23 through a pulse width modulation (PWM) signal to achieve clockwise / counterclockwise rotation switching of the rotating disk 21.

[0061] The image processing module, which is equipped with a deep learning vision algorithm, analyzes the real-time video stream transmitted by the image collector 24:

[0062] Pollution identification: Detect pollution characteristics such as abnormal water color (such as black and smelly water), floating objects (such as garbage and oil), and algae accumulation;

[0063] Index calculation: Water quality parameters (such as turbidity and chlorophyll a concentration) are estimated through image spectral analysis and compared with preset thresholds (such as Class III surface water standards);

[0064] Early warning trigger: When pollution indicators exceed the standard or a sudden pollution incident is identified, an early warning signal containing a timestamp and pollution type is generated.

[0065] The early warning execution module responds to the early warning signal from the image processing module and executes the multi-level linkage early warning mechanism:

[0066] On-site warning: control the warning light 15 to flash red at a frequency of 2Hz to warn surrounding personnel;

[0067] Terminal display: A pollution area marking box pops up on the terminal screen of the monitoring center, superimposing real-time images and a list of exceeded parameters, supporting historical data backtracking and comparison;

[0068] Remote notification: Send early warning text messages to preset management terminals such as environmental protection departments and operation and maintenance personnel through 4G / 5G wireless communication units.

[0069] Through the linkage of drive control, image processing and early warning execution modules, real-time analysis of pollution images and multi-level early warning response are achieved. It has the advantages of high visualization and strong automatic linkage. It can be widely used in scenarios such as blue-green algae monitoring in drinking water sources, identification of illegal discharge of industrial wastewater, and tracking of river ecological restoration effects, providing real-time and intelligent decision-making support for water environment management.

[0070] In summary, the present invention discloses a monitoring and early warning device for water environment management, which realizes all-round monitoring of the water surface and underwater environment through the integrated design of a floating seat and a rotating monitor. The rotating monitor can realize self-cleaning when rotating to switch the monitoring angle of view, which can greatly extend the manual maintenance cycle and reduce the total operation and maintenance cost. The wiping cleaning parts can be easily replaced through a detachable plug-in structure, and the elastic pressure component composed of a slider and a coil spring can enhance the cleaning force of the lens; the lifting component composed of a guide wheel and a torsion spring can automatically form a maintenance operation space through the rotation of the rotating disk, and the replacement of cleaning parts can be completed without manual labor. The rotary driver drives the rotating disk to rotate, so that the image collector switches the monitoring angle of view along with the hollow slot, and the integrated fill light device ensures the monitoring effect of the weak light environment. The intelligent monitoring system analyzes the image data in real time through the linkage of the drive control, image processing and early warning execution modules. When it is detected that the pollution index exceeds the standard, the warning light automatically flashes to alarm, and the pollution area information is displayed on the monitoring terminal at the same time, and an early warning text message is sent to the management terminal. The device has the characteristics of self-cleaning, low maintenance, and intelligent early warning. It can be widely used in scenarios such as drinking water source monitoring, industrial wastewater supervision, and river ecological restoration tracking, providing efficient and intelligent technical support for water environment management.
