Description

Technical Field

[0001] This invention belongs to the field of water quality monitoring technology and relates to a self-cleaning water quality monitoring device. Background Technology

[0002] Buoy-type water quality monitoring stations are now an important device for water quality monitoring in most lakes, rivers, and oceans. Traditional buoy-type water quality monitoring stations use buoys to install detection devices and main control systems inside, while solar panels are installed on top of the buoys to power the equipment and charge the batteries. At the same time, the buoys are also equipped with wind direction and speed monitoring equipment, as well as air temperature and humidity monitoring equipment. The installation of these devices on the buoys makes the monitoring of the aquatic environment extremely convenient, fast, and timely.

[0003] However, in traditional buoy-type water quality monitoring stations, the sensors are usually installed at the bottom of the buoy and immersed in the water. After prolonged use, algae, snails, and other microorganisms easily grow on the bottom of the buoy and the surface of the sensor, making the buoy heavier. This affects the normal operation of the sensor and also causes the buoy to sink, affecting the monitoring of the device. In existing technologies, a drive device is generally used to drive a brush to scrape the sensor to remove microorganisms. However, the brush itself is placed in the water for a long time, and a large number of microorganisms will grow on its surface. This will increase the weight of the entire device, affecting the normal operation of the buoy, and it cannot thoroughly clean the sensor. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning water quality monitoring device to solve the problems in the prior art where the brush itself is placed in water for a long time, and a large number of microorganisms grow on its surface, which increases the weight of the entire device and makes it impossible to thoroughly clean the sensor.

[0005] A self-cleaning water quality monitoring device includes a support column, a buoy box, a water quality monitoring component mounted on the buoy box, and a cleaning component. The support column has a spiral spline groove on its surface. The buoy box has a through hole in its middle and is fitted onto the surface of the support column through the through hole. The inside of the through hole has a spline that slides with the spline groove. The support column is equipped with the cleaning component and a pressing component. When the buoy box is at the top of the spline groove, one edge of the buoy box abuts against the edge of the cleaning component, fixing the cleaning component in place. When the pressing component presses the buoy box, causing the buoy box to rotate and descend along the spline groove, and the buoy box is located in the middle of the spline groove, the cleaning component moves to the bottom of the buoy box and rotates to scrape off the deposits on the bottom of the buoy box.

[0006] Preferably, the buoy box has an waist-shaped structure, with an opening on one side and the distance between the opening and the support column being less than the distance between the other edge of the buoy box and the support column. The top of the buoy box is also provided with a stop bar. When the buoy box is located at the top of the spline groove, the top of the stop bar blocks the cleaning assembly to prevent the cleaning assembly from rotating.

[0007] Preferably, the cleaning assembly includes a rotating impeller, a fixed bracket, and a brush plate. The rotating impeller is rotatably connected to the top of the support column via a rotating sleeve. The bottom of the rotating sleeve is fixedly connected to the fixed bracket, and the bottom of the fixed bracket is rotatably connected to the brush plate via a hinge shaft. The end of the brush plate is provided with an elastic part. A spring is also fixedly connected between the brush plate and the fixed bracket. The spline is located at the top of the spline groove. The edge of the buoy box presses against the surface of the brush plate and compresses the spring. When the spline is located in the middle of the spline groove, the buoy box rotates with the spline groove, causing the opening to rotate to below the brush plate. The spring drives the brush plate to move to below the buoy box, and the elastic part is attached to the surface of the support column. When the spline is located at the bottom of the spline groove, the buoy box presses the brush plate and stretches the spring. During the rotation of the brush plate driven by the rotating impeller, when the brush plate encounters the opening, the spring drives the brush plate to move above the buoy box.

[0008] Preferably, the elastic part includes a protrusion and a second spring, the end of the brush plate has a groove, the protrusion is slidably connected in the groove, and the second spring is fixedly connected between the protrusion and the groove.

[0009] Preferably, the pressing assembly includes a fixed plate and a drive cylinder. The drive cylinder is fixedly connected to one side of the support column by means of the fixed plate. The piston rod of the drive cylinder faces the buoy box and the drive cylinder presses the buoy box to make the buoy box rotate around the spline groove.

[0010] Preferably, the support column is internally embedded with a storage battery and a generator, the rotating impeller drives the central shaft of the generator to rotate, the storage battery is electrically connected to the generator, and the storage battery supplies power to the drive cylinder.

[0011] Preferably, the water quality monitoring component further includes multiple water quality monitoring sensors, and the bottom of the buoy box is provided with multiple water quality monitoring sensors, and the battery powers the water quality monitoring sensors.

[0012] This invention includes a support column, a cleaning component, and a pressing component. A water quality monitoring component is installed on the buoy box. Under normal conditions, when the buoy box is located at the top of the spline groove, one edge of the buoy box abuts against the edge of the cleaning component, fixing the cleaning component in place. The water quality monitoring component monitors the water quality. If excessive microorganisms grow at the bottom of the buoy box, the pressing component presses the buoy box downwards, causing it to move downwards along the spline groove and move the opening of the buoy box below the cleaning component. After the cleaning component releases pressure, a spring drives the brush plate to move below the buoy box, with the elastic part adhering to the surface of the support column. The rotating impeller drives the brush plate to rotate around the support column, thereby utilizing the brush plate... After scraping away microorganisms from the bottom of the buoy box, the pressing component continues to move the buoy box downwards. The buoy box presses the brush plate, stretching the spring. As the rotating impeller drives the brush plate to rotate, when the brush plate encounters the opening, the spring moves the brush plate to the top of the buoy box. Then, the pressing component retracts, and under the action of buoyancy, the buoy box moves upwards, squeezing the brush plate and spring, returning to the initial state. When not in use, the brush plate remains above the water surface, preventing excessive microorganism growth and ensuring cleaning effectiveness. It also prevents the buoy from sinking. When in use, external wind energy is used to scrape away microorganisms from the bottom of the buoy box, making it more energy-efficient. Attached Figure Description

[0023] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.

[0024] like Figure 1-6 As shown, the present invention provides a self-cleaning water quality monitoring device, including a support column 1, a buoy box 12, a water quality monitoring component disposed on the buoy box 12, and a cleaning component 3. The surface of the support column 1 has a spiral spline groove 11. The buoy box 12 has a through hole 13 in the middle and is fitted onto the surface of the support column 1 by means of the through hole 13. The inside of the through hole 13 is provided with a spline 14 that slides with the spline groove 11. The support column 1 is provided with the cleaning component 3 and a pressing component 2. When the buoy box 12 is located at the top of the spline groove 11, one edge of the buoy box 12 abuts against the edge of the cleaning component 3 and fixes the cleaning component 3. When the pressing component 2 presses the buoy box 12, causing the buoy box 12 to rotate and descend along the spline groove 11 and when the buoy box 12 is located in the middle of the spline groove 11, the cleaning component 3 moves to the bottom of the buoy box 12 and rotates to scrape off the deposits on the bottom of the buoy box 12.

[0025] The buoy box 12 has an waist-shaped structure. One side of the buoy box 12 has an opening 15, and the distance between the opening 15 and the support column 1 is less than the distance between the other edge of the buoy box 12 and the support column 1. The top of the buoy box 12 is also equipped with a stop bar 16. When the buoy box 12 is located at the top of the spline groove 11, the top of the stop bar 16 blocks the cleaning assembly 3 to prevent the cleaning assembly 3 from rotating. The cleaning assembly 3 includes a rotating impeller 31, a fixed bracket 33, and a brush plate 34. The rotating impeller 31 is rotatably connected to the top of the support column 1 via a rotating sleeve 32. The bottom of the rotating sleeve 32 is fixedly connected to the fixed bracket 33, and the bottom of the fixed bracket 33 is rotatably connected to the brush plate 34 via a hinge shaft 35. The end of the brush plate 34 is provided with an elastic part 37, which includes a protrusion 39 and a spring 38. The end of the brush plate 34 has a groove, and the protrusion 39 is slidably connected within the groove. 9. A second spring 38 is fixedly connected between the protrusion 39 and the groove, and a first spring 36 is also fixedly connected between the brush plate 34 and the fixed bracket 33. The spline 14 is located at the top of the spline groove 11. The edge of the buoy box 12 presses against the surface of the brush plate 34 and compresses the first spring 36. When the spline 14 is located in the middle of the spline groove 11, the buoy box 12 rotates with the spline groove 11 to change direction, causing the opening 15 to rotate to the brush plate 38. Below 4, the spring 36 drives the brush plate 34 to move to the bottom of the buoy box 12 and the elastic part 37 is attached to the surface of the support column 1. When the spline 14 is located at the bottom of the spline groove 11, the buoy box 12 presses the brush plate 34 and stretches the spring 36. During the process of the rotating impeller 31 driving the brush plate 34 to rotate, when the brush plate 34 encounters the opening 15, the spring 36 drives the brush plate 34 to move to the top of the buoy box 12.

[0026] In the initial state, the buoy box 12 is positioned at the top of the spline groove 11 due to buoyancy, and the stop rod 16 also blocks the rotating impeller 31, preventing the impeller 31 from operating. With the impeller 31 not rotating, the brush plate 34 and the fixed bracket 33 also do not rotate. At this time, the protrusion 39 protrudes from the groove, and the spring 36 is compressed. The spring 36 drives the brush plate 34 to press against one side surface of the buoy box 12. During cleaning, the piston rod of the drive cylinder 22 moves downwards, thereby causing the buoy box 12 to be lowered by the spline 14. Moving downwards along the spline groove 11, due to the spiral structure of the spline groove 11, the side of the buoy box 12 with the opening 15 will move to below the brush plate 34. Driven by the first spring 36 and influenced by the gravity of the brush plate 34, the brush plate 34 will move downwards along the opening 15. The elastic force of the first spring 36 is greater than the pressure on the protrusion 39, so the protrusion 39 will retract. The second spring 38 contracts and stores energy, causing the brush plate 34 to move completely to below the buoy box 12. At this time, the second spring 38 releases energy, driving the protrusion 39 to retract. 9. The protrusion 39 moves outward, causing it to adhere to the surface of the support column 1. The wind power drives the rotating impeller 31 to work, which in turn drives the brush plate 34 to scrape away microorganisms at the bottom of the buoy box 12. Because the protrusion 39 extends outward, the brush plate 34 will not pass through the opening 15 and move above the buoy box 12 during rotation. After cleaning, the drive cylinder 22 continues to drive the buoy box 12 to move downward. At this time, the downward movement of the buoy box 12 will press down on the brush plate 34, causing the brush plate 34 to rotate downward. The spring 36 is in a state of... In the stretched state, the rotating impeller 31 continuously drives the brush plate 34 to rotate, causing the protrusion 39 to move further and further away from the support column 1. During the rotation, once the brush plate 34 contacts the opening, under the tension of the spring 36, the brush plate 34 can pass upward through the opening 15 and move above the buoy box 12. Finally, the pressing component 2 is released, the buoy box 12 rotates and moves upward, squeezing the brush plate 34, causing the spring 36 to be compressed and return to the energy storage state. The stop lever 16 will also move upward to the rotating impeller 31, blocking the rotation of the rotating impeller 31.

[0027] The pressing assembly 2 includes a fixing plate 21 and a drive cylinder 22. The drive cylinder 22 is fixedly connected to one side of the support column 1 via the fixing plate 21. The piston rod of the drive cylinder 22 faces the buoy box 12, and the drive cylinder 22 presses the buoy box 12, causing the buoy box 12 to rotate around the spline groove 11. A battery and a generator are embedded inside the support column 1. The rotating impeller 31 drives the central shaft of the generator to rotate. The battery is electrically connected to the generator and supplies power to the drive cylinder 22.

[0028] When the wind drives the rotating impeller 31 to rotate, the rotating impeller will also drive the central shaft of the generator to rotate, thereby generating electricity to store electricity in the battery. The battery can supply power to the water quality monitoring components, micro motors, and drive cylinders, eliminating the need for an external power source.

[0029] The water quality monitoring component also includes multiple water quality monitoring sensors. Multiple water quality monitoring sensors are provided at the bottom of the buoy box 12, and the battery powers the water quality monitoring sensors.

[0030] The multiple water quality monitoring sensors may include nitrogen and phosphorus sensors, oxygen content sensors, residual chlorine sensors, pH sensors, and turbidity sensors to monitor water quality. The water quality monitoring component may also include a controller assembly and a wireless transmission terminal. The controller assembly is used to receive data sensed by the multiple water quality monitoring sensors and transmit the data to a remote terminal through the wireless transmission terminal to realize data transmission.

[0031] In the initial state, the buoy box 12 is positioned at the top of the spline groove 11 due to buoyancy, and the stop rod 16 also blocks the rotating impeller 31, preventing the impeller 31 from operating. With the impeller 31 not rotating, the brush plate 34 and the fixed bracket 33 also do not rotate. At this time, the protrusion 39 protrudes from the groove, and the spring 36 is compressed. The spring 36 drives the brush plate 34 to press against one side surface of the buoy box 12. During cleaning, the piston rod of the drive cylinder 22 moves downward, thereby causing the buoy box 12 to move downward along the spline groove 11 using the spline 14. The keyway 11 has a spiral structure, so the side of the buoy box 12 with the opening 15 will move to the bottom of the brush plate 34. Driven by the first spring 36 and under the influence of the gravity of the brush plate 34, the brush plate 34 will move downward along the opening 15. The elastic force of the first spring 36 is greater than the pressure on the protrusion 39, so the protrusion 39 will retract. The second spring 38 contracts and stores energy, so that the brush plate 34 moves completely to the bottom of the buoy box 12. At this time, the second spring 38 releases energy, driving the protrusion 39 to move outward, so that the protrusion 39 is attached to the surface of the support column 1. The wind drives the rotating blade. When wheel 31 operates, it drives brush plate 34 to scrape away microorganisms at the bottom of buoy box 12. Simultaneously, it rotates the central shaft of generator, generating electricity to power the battery. The battery supplies power to the water quality monitoring components, micro-motor, and drive cylinder, eliminating the need for an external power source and increasing energy efficiency. Because the protrusion 39 extends outwards, brush plate 34 will not pass through opening 15 and move above buoy box 12 during rotation. After cleaning, drive cylinder 22 continues to move buoy box 12 downwards, pressing down on brush plate 34. The brush plate 34 is rotated downwards, and the spring 36 is in a stretched state. The rotating impeller 31 continues to drive the brush plate 34 to rotate, causing the protrusion 39 to move further and further away from the support column 1. During the rotation, once the brush plate 34 contacts the opening, under the stretch of the spring 36, the brush plate 34 can pass upward through the opening 15 and move above the buoy box 12. Finally, the pressing component 2 is released, and the buoy box 12 rotates and moves upwards, squeezing the brush plate 34, causing the spring 36 to be compressed and return to the energy storage state. The stop lever 16 will also move upwards to the rotating impeller 31, blocking the rotation of the rotating impeller 31.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
