Abstract
Description
Technical Field
[0001] This invention belongs to the field of environmental monitoring equipment technology, specifically a water source environmental risk early warning device and method. Background Technology
[0002] During the construction and operation of the wetland road network, if the production wastewater and domestic sewage generated during construction are directly discharged into the wetland, it will pollute the wetland water resources. At the same time, the washing of construction materials, vehicle washing, exhaust fumes emitted by vehicles traveling on the road network, and fuel leaks will all cause certain pollution to the water quality of the wetland ecosystem. Therefore, monitoring and early warning of water quality is one of the necessary means to effectively understand and improve the pollution situation.
[0003] When monitoring and issuing early warnings for water sources around the road network, installing detection and early warning devices in the water sources for rapid detection and real-time early warning is one of the effective ways to enhance the timeliness of water source risk warnings. Moreover, since the water area in the water source area is relatively large, the distribution and density of detection points have a significant impact on the accuracy of environmental risk monitoring of the water source area.
[0004] To enhance the comprehensiveness of environmental monitoring of water sources, related technologies typically employ mobile float monitoring stations to conduct comprehensive water quality monitoring. During real-time monitoring, the float monitoring station moves within the water due to the impact of water flow. During this movement, the float monitoring station automatically monitors water quality and transmits the results to the central monitoring station, thus achieving comprehensive monitoring of the water quality of the water source. However, on the one hand, the movement speed of the float monitoring station varies significantly depending on whether the water flow trend in the water source is weak or strong. The former results in low mobility or even inability to move, leading to a loss of its mobile monitoring capability. On the other hand, the latter results in excessively fast movement, causing the float monitoring station to converge in areas with gentler flow, resulting in insufficient dwell time in areas with faster water flow. This leads to distorted or insufficient monitoring results, causing inaccurate water quality monitoring data in the water source. Therefore, this invention proposes a water source environmental risk early warning device and method to solve the above-mentioned technical problems.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0011] A circulation pump is fixedly installed at the bottom of the float plate, and the circulation pump is used to draw and spray water.
[0012] Specifically, it also includes a constant speed winding assembly, which is mounted on a fixed insert rod and is used to control the tension of the connecting rope;
[0013] The constant speed take-up assembly includes a take-up box, which is mounted on a fixed insert rod. The take-up roller extends into the take-up box and is rotatably sleeved on the fixed insert rod.
[0014] The drive motor and drive wheel assembly are provided. The drive motor is fixedly mounted on the take-up box. The drive wheel assembly is mounted on both the output end of the drive motor and the take-up roller for transmitting power between the drive motor and the take-up roller.
[0015] Specifically, the winding box has a through hole, the connecting rope extends into the through hole, and a cleaning sponge is fixedly installed inside the through hole, and the cleaning sponge has a conical design.
[0016] Specifically, a support plate is fixedly installed at the bottom of the winding box, and both the support plate and the winding box are slidably installed on the fixed insert rod, with the support plate floating on the water surface.
[0017] Specifically, a water spray ring is rotatably connected to the edge of the float plate, and water spray holes are opened on the circumferential surface of the water spray ring. The inner cavity of the water spray ring is connected to the output end of the circulation pump.
[0018] Specifically, a rotating ring is rotatably mounted on the float plate, and the rotating ring is fixedly connected to the water spray ring through a guide rod. A sliding groove is provided on the float plate, and a transmission plate is elastically connected to the sliding groove through a spring.

[0019] Specifically, solar panels are installed on both the winding box and the floating plate, and the solar panels are used to power the drive motor, the circulating pump, and the detector body.

Each solar cell array is equipped with a cleaning brush, and the cleaning brush is fixedly connected to the support plate and the rotating ring respectively through guide rods.
[0021] A method for early warning of environmental risks in water sources, comprising the following steps:
[0022] S1: Install the early warning equipment evenly in the river channel of the water source and connect the early warning device to the external monitoring equipment.

[0023] S2: The solar panel converts solar energy into electrical energy to power the monitoring equipment, circulation pump and drive motor.

[0024] S3: During the cyclical release and retraction of the connecting rope, the float detection component is pulled to move in the river. At the same time, the circulation pump starts and sprays water, which makes the movement path of the float detection component more diverse.

At the same time, because the float detection component is restricted by the connecting rope and the position of the fixed rod is fixed, it is easy for staff to locate the float detection component when it needs to be inspected or maintained during long-term use. During the early warning process, because the detection range of the float detection component is relatively fixed, staff can quickly and accurately determine the approximate location of the water area where the early warning is located based on the number of the float detection component, which facilitates timely remedial measures.
[0028] 2. The water source environmental risk early warning device and method of the present invention, with the setting of the constant speed winding component, on the one hand, can enhance the movement effect of the float detection component in the river by winding and unwinding the connecting rope in conjunction with the impact of the water flow, thereby enhancing the uniformity and comprehensiveness of the detection of regional water quality. On the other hand, the relatively fixed winding and unwinding speed of the connecting rope promotes the stability of the float movement component, further enhancing the uniformity of the detection by the float detection component.

Detailed Implementation
[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0038] like Figures 1 to 6 As shown, the present invention provides a water source environmental risk early warning device, which includes a float detection component. The float detection component includes a detector body 1 and a float plate 11. The detector body 1 is installed on the float plate 11 and is used to detect the water flow and water quality. The detector body 1 is also equipped with a communication component for real-time communication.
[0039] It also includes a fixed-point extension component, which is installed in the river channel and connected to the float detection component to control the distance of the float detection component;
[0040] The fixed-point extension component includes a fixed insertion rod 2, which is fixedly installed in the river channel, and the height of the fixed insertion rod 2 is greater than the depth of the river channel;
[0041] A take-up roller 21 is provided with a connecting rope 22, one end of which is fixedly connected to the take-up roller 21 and the other end is connected to the detector body 1.
[0042] A circulation pump 23 is fixedly installed at the bottom of the float plate 11. The circulation pump 23 is used to draw and spray water.
[0043] In monitoring the water source environment in wetlands traversed by road networks, periodic testing of parameters such as pH, chemical oxygen demand (COD), BOD5, total nitrogen, and total phosphorus in the water flow is conducted. Based on these parameters, the pollution status of the road network construction and operation on the water source is assessed, allowing for timely remedial or pollution prevention measures to reduce pollution. Specifically, the timeliness and comprehensiveness of water flow monitoring significantly impact the results. In actual monitoring, a fixed-point extension team will be used... The components are installed in the river channel, and the fixed-point extension components are evenly distributed according to the distribution of water sources in the water source area. Then, the float detection components are connected and paired with the fixed-point extension components one by one. The float detection components are placed in the river channel. Under the buoyancy of the float plate 11, the detector body 1 installed on the float plate 11 floats on the surface of the river channel, and the sampling end of the detector body 1 penetrates the float plate 11 and is in contact with the water. Under the control of the preset program inside the detector body 1, the detector body 1 performs periodic detection of the river water. During long-term monitoring, The float detection component is connected to the fixed-point extension component, which controls the movement distance of the float detection component. Specifically, the fixed insertion rod 2 is fixedly inserted into the riverbed mud, and the winding roller 21 is installed on the fixed insertion rod 2. The connecting rope 22 fixed on the winding roller 21 is connected to the float detection component. Therefore, when the water flow in the riverbed is relatively still, the circulation pump 23 continuously draws water and discharges water. With the help of the water discharge, the water flow in the riverbed is made to have a certain movement trend, which in turn causes the float detection component to move in the riverbed. The movement of the float detection components is caused by the flow of water in the river. During this movement, the connecting rope 22 on the winding roller 21 restricts the range of movement of the float detection components. At the same time, the circulation pump 23 draws and sprays water, which disturbs the water flow. Combined with the impact of the water flow and the limiting effect of the connecting rope 22, the diversity of the movement trajectory of the float detection components is enhanced, so that multiple float detection components are evenly distributed in the water source and can move within a range, thereby enhancing the uniformity of water quality detection in the water source.
[0044] This invention uses components such as a fixed rod 2 and a connecting rope 22 to confine the movement of the float detection component within a certain range. Combined with a circulation pump 23, this enhances the diversity of the float's movement trajectory, resulting in a more even distribution of the float detection component in the water source area. This effectively improves the comprehensiveness of water quality monitoring at the water source. Furthermore, because the float detection component is restricted by the connecting rope 22 and the fixed position of the fixed rod 2, it is easy for staff to locate the component when it needs inspection or maintenance during long-term use. During early warning processes, the relatively fixed detection range of the float detection component allows staff to quickly and accurately determine the approximate location of the warning area based on the component's serial number, facilitating timely remedial measures.
[0045] As a preferred embodiment of the present invention, it further includes a constant speed winding assembly, which is mounted on the fixed insertion rod 2 and is used to control the tension of the connecting rope 22.
[0046] The constant speed winding assembly includes a winding box 24, which is mounted on a fixed insert rod 2. The winding roller 21 extends into the winding box 24 and is rotatably sleeved on the fixed insert rod 2.
[0047] The drive motor 25 and the drive wheel set 26 are provided. The drive motor 25 is fixedly mounted on the take-up box 24. The drive wheel set 26 is mounted on the output end of the drive motor 25 and the take-up roller 21 together, which is used for the transmission of power between the drive motor 25 and the take-up roller 21.
[0048] In the long-term monitoring and early warning process, in order to further enhance the movement trend of the float detection component within the specified range, a drive motor 25 and a drive wheel set 26 are set. Under the action of a preset program, the rotation direction of the drive motor 25 changes periodically, and when the drive motor 25 rotates, it drives the take-up roller 21 to rotate through the drive wheel set 26. Specifically, in this embodiment, the drive wheel set 26 adopts a worm gear transmission, with the worm fixed at the output end of the drive motor 25 and the worm gear fixed on the take-up roller 21. However, in the embodiments of this application, other structures can also be used for the transmission between the drive motor 25 and the take-up roller 21. When the take-up roller 21 rotates under the drive of the drive motor 25, the connecting rope 22 on the take-up roller 21 is gradually wound and tightened or unwound and loosened. The take-up box 24 is set... In conjunction with the winding roller 21, the winding or unwinding of the connecting rope 22 is guided. When the connecting rope 22 is gradually unwinding, the range of motion of the float detection component increases under the impact of the water flow or the reaction force of the water jet from the circulating pump 23. When the connecting rope 22 is gradually winding up, the range of motion of the float detection component decreases. Since the winding and unwinding speed of the connecting rope 22 is fixed, the movement speed of the float detection component is limited. Therefore, the setting of the constant speed winding component can, on the one hand, enhance the movement effect of the float detection component in the river channel by winding and unwinding the connecting rope 22 in conjunction with the impact of the water flow, thereby enhancing the uniformity and comprehensiveness of the regional water quality detection. On the other hand, the relatively fixed winding and unwinding speed of the connecting rope 22 promotes the stability of the float movement component, further enhancing the uniformity of the float detection component's detection.
[0049] In a preferred embodiment of the present invention, the winding box 24 is provided with a through hole 27, the connecting rope 22 extends into the through hole 27, and a cleaning sponge 28 is fixedly installed in the through hole 27, and the cleaning sponge 28 is tapered.
[0050] By setting up a cleaning sponge 28 with a conical design, the cleaning sponge 28 is located on the periphery of the connecting rope 22, and the end of the cleaning sponge 28 is fixed near the inner cavity of the winding box 24. Therefore, when the connecting rope 22 is wound up, under the action of friction, the cleaning sponge 28 contracts into the through hole 27, enhancing the friction effect on the connecting rope 22, thereby enhancing the cleaning effect on the surface of the connecting rope 22. When the connecting rope 22 is unwound, the cleaning sponge 28 moves outward from the through hole 27, causing the cleaning sponge 28 to unfold, thereby reducing the friction effect on the connecting rope 22, making it easier for the connecting rope 22 to be pulled by the float detection component.
[0051] In a preferred embodiment of the present invention, a support plate 3 is fixedly installed at the bottom of the winding box 24, and both the support plate 3 and the winding box 24 are slidably installed on the fixed insert rod 2, with the support plate 3 floating on the water surface;
[0052] During long-term monitoring and early warning, the water level in the river channel of the water source changes. Therefore, a support plate 3 is set up, and the winding box 24 is installed on the support plate 3. The support plate 3 is slidably installed on the fixed plug rod 2. When the water level changes, the support plate 3, which is made of low-density material, floats on the water surface and automatically rises and falls with the change of water level, so that the connecting rope 22 always remains parallel, which facilitates the movement of the float detection component.
[0053] In a preferred embodiment of the present invention, a water spray ring 31 is rotatably connected to the edge of the float 11, and water spray holes 32 are opened on the circumferential surface of the water spray ring 31. The inner cavity of the water spray ring 31 is connected to the output end of the circulation pump 23.
[0054] By setting a water spray ring 31, which is rotatably mounted on the edge of the float 11 and whose inner cavity is connected to the output end of the circulation pump 23, the circulation pump 23 draws water and then pumps it into the water spray ring 31. The water is then sprayed outward through the water spray holes 32 on the water spray ring 31, thus limiting the path of the sprayed water. This causes the reaction force generated when the water is sprayed to act on the float 11, which facilitates interference with the movement path of the float 11 and enhances the diversity of the movement path of the float 11.
[0055] In a preferred embodiment of the present invention, a rotating ring 4 is rotatably mounted on the float 11, and the rotating ring 4 is fixedly connected to the water spray ring 31 through a guide rod. A sliding groove 41 is provided on the float 11, and a transmission plate 42 is elastically connected to the sliding groove 41 through a spring. The transmission plate 42 drives the rotating ring 4, and the transmission plate 42 is fixedly connected to the connecting rope 22.
[0056] When the constant-speed winding assembly is activated, causing the connecting rope 22 to be wound up, the connecting rope 22 pulls the transmission plate 42, and the transmission plate 42 drives the rotating ring 4. Specifically, in this embodiment, the surfaces of the transmission plate 42 and the rotating ring 4 are rough, and the two are in close contact, using friction for transmission. When the transmission plate 42 is pulled, there is friction between the transmission plate 42 and the rotating ring 4. However, the float detection assembly floats on the water surface. When the float plate 11 moves, it is subject to water resistance. At the same time, because the rotating ring 4 is rotatably mounted on the float plate 11, there is a tendency for relative movement between the transmission plate 42 and the rotating ring 4. At this time, the rotating ring 4 rotates on the float plate 11. Since the rotating ring 4 and the water spray ring 31 are fixed by the guide rod... Therefore, when the rotating ring 4 rotates, it drives the water spray ring 31 to rotate, which in turn causes the position of the water spray holes 32 on the water spray ring 31 to change. Under the action of the water flow sprayed from the water spray holes 32, the movement trend of the float 11 becomes more varied. When the transmission plate 42 moves to the end of the sliding groove 41, the connecting rope 22 and the transmission plate 42 directly pull the float 11 to move, causing the float 11 to move towards the fixed insertion rod 2. When the constant speed winding assembly stops, the transmission plate 42 returns to its original position under the action of the spring in the sliding groove 41. During this process, the rotating ring 4 and the water spray ring 31 rotate in opposite directions, further increasing the degree of disturbance to the position of the float 11. During the monitoring and early warning process, the movement trajectory of the float 11 becomes more varied.
[0057] In a preferred embodiment of the present invention, solar cell arrays 43 are installed on both the winding box 24 and the float 11. The solar cell arrays 43 are used to power the drive motor 25, the circulation pump 23 and the detector body 1.
[0058] In practical applications, by setting up a solar cell array 43, which is a combination of solar panels and power supply circuits, solar energy is converted into electrical energy and supplied to the drive motor 25, the circulation pump 23 and the detector body 1, thereby reducing the proportion of external circuits supplying power to the overall device and enhancing the energy efficiency of the device.
[0059] In a preferred embodiment of the present invention, the solar cell arrays 43 are all plate-shaped. The solar cell arrays 43 located on the winding box 24 are fixedly connected to the winding roller 21, and the solar cell arrays 43 located on the floating plate 11 are fixedly connected to the detector body 1. Each solar cell array 43 is equipped with a cleaning brush 44, and the cleaning brush 44 is fixedly connected to the bearing plate 3 and the rotating ring 4 respectively through guide rods.
[0060] During long-term use, when the winding roller 21 and the rotating ring 4 rotate, the winding roller 21 drives the solar cell array 43 above the winding box 24 to rotate, and the rotating ring 4 drives the cleaning brush 44 on the floating plate 11 to move, causing relative rotation between the solar cell array 43 and the cleaning brush 44. The cleaning brush 44 is then used to clean the upper surface of the solar cell array 43, thereby reducing the impact of fallen leaves, debris, etc. on the power generation efficiency of the solar cell array 43.
[0061] A method for early warning of environmental risks in water sources, comprising the following steps:
[0062] S1: Install the early warning equipment evenly in the river channel of the water source and connect the early warning device to the external monitoring equipment. The external monitoring equipment monitors the output information of the early warning device. When the output device reaches the preset threshold, the external monitoring equipment sends a signal.
[0063] S2: The solar panel 43 converts solar energy into electrical energy to power the monitoring equipment, the circulating pump 23 and the drive motor 25. After the drive motor 25 starts, it drives the winding roller 21 to perform forward and reverse rotation through the drive wheel group 26, causing the connecting rope 22 to be wound and unwound in a cycle.
[0064] S3: During the cyclical release and retraction of the connecting rope 22, the float detection component is pulled to move in the river channel. At the same time, the circulation pump 23 is started, spraying water to diversify the movement path of the float detection component.
[0065] S4: The float detection component detects water quality at regular time intervals under the pre-set program and transmits the detection results to external monitoring equipment through the communication component.
