[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 This embodiment provides an automatically cleanable water quality monitoring probe, including a water quality monitoring probe body 100 and a mounting base 103. The mounting base 103 is installed on the detection end of the water quality monitoring probe body 100 by a fixing member. A rotating groove 107 is formed on the top of one side of the mounting base 103. A connecting post 300 is rotatably connected to the inner cavity of the rotating groove 107. One side surface of the connecting post 300 protrudes from the mounting base 103. A 7-shaped plate 201 is provided. One side surface of the 7-shaped plate 201 is fixedly connected to the surface of the connecting post 300. The inner cavity of the 7-shaped plate 201 is provided with a scraper 200 for scraping off the adhering substances on the surface of the monitoring window of the water quality monitoring probe body 100. The groove 109 is located at the bottom of one side of the mounting base 103. The groove 109 is equipped with a drive component for driving the connecting column 300 to rotate, thereby causing the scraper 200 to swing back and forth. The mounting base 103 is equipped with a control component for controlling the drive component. Through the arrangement of the drive component and the scraper 200, the power of the drive component is transmitted to the 7-shaped plate 201 through the connecting column 300, causing the 7-shaped plate 201 to swing back and forth. During the back and forth swing of the scraper 200, the deposits on the surface of the monitoring window can be scraped off, thereby achieving the purpose of cleaning the window and preventing the monitoring window from being blocked by sludge, which would affect the monitoring work.

[0031] Furthermore, the driving component includes a motor 305 inserted into the cavity of the receiving groove 109. The output shaft of the motor 305 is fixedly connected to an adapter post 303. A limit strip 304 is fixedly connected to one side of the adapter post 303. A slot 302 adapted to the adapter post 303 and the limit strip 304 is provided at the bottom of the connecting post 300. The adapter post 303 and the limit strip 304 are inserted into the cavity of the slot 302. An anti-disengagement component is provided at the opening of the receiving groove 109 to limit the motor 305 and prevent the motor 305 from disengaging from the cavity of the receiving groove 109. The anti-disengagement component includes a fixing plate 106 provided at the opening of the receiving groove 109. Screws 105 are respectively inserted into both sides of the fixing plate 106. One end of each of the two sets of screws 105 passes through the corresponding side surface of the fixing plate 106 and is threaded. Attached to the bottom of the mounting base 103, the connection is enhanced by the setting of the driving component and the limiting component, and the cooperation design between the limiting strip 304 on the connecting column 300 and the slot 302. This prevents loosening or slippage during rotation and ensures the reliability of power transmission. The anti-detachment component at the opening of the receiving slot 109 can effectively prevent the motor 305 from detaching from the receiving slot 109 due to vibration, rotational force, etc., further ensuring the stability of the entire driving component, reducing the cleaning device failure that may be caused by the displacement of the motor 305, and extending the service life of the device. At the same time, when the motor 305 needs to be replaced, the screw 105 can be removed to release the restriction on the fixing plate 106, making it easy to remove the fixing plate 106 and improving the convenience of replacing the motor 305.

[0032] Among them, motor 305 is one type of servo motor or oscillating motor.

[0033] Furthermore, the control component includes a mounting slot 401 located at the bottom of the mounting base 103. A microcontroller 400 is installed inside the mounting slot 401, and the motor 305 is controlled by the microcontroller 400. A sealing plate 104 is installed at the opening of the mounting slot 401, and the sealing plate 104 is bonded to the opening of the mounting slot 401 with sealant. Through the configuration of the microcontroller 400 and the sealing plate 104, the microcontroller 400 controls the motor 305, enabling various control modes such as precise timed cleaning and cleaning triggered by monitoring data, thereby improving the intelligence of cleaning. At the same time, the sealing plate 104 bonded to the opening of the mounting slot 401 with sealant can effectively prevent external moisture, dust and other impurities from entering the interior of the mounting slot 401, protecting the microcontroller 400 and other electronic components from corrosion and damage, and ensuring the long-term stable operation of the control component.

[0034] The microcontroller 400 can be an STC89C51 microcontroller.

[0035] Preferably, the fixing component includes a fixing ring 101 fixedly installed on the top of the mounting base 103. The fixing ring 101 is sleeved on the end of the water quality monitoring probe body 100. Two first bolts 102 are threadedly connected to both sides of the fixing ring 101. The two sets of first bolts 102 are threaded through the corresponding side surfaces of the fixing ring 101 and abut against both sides of the water quality monitoring probe body 100. Through the fixing component, the fixing ring 101 is sleeved on the end of the water quality monitoring probe body 100, and the first bolts 102 on both sides are threaded through the fixing ring 101 and abut against both sides of the probe body, realizing a firm connection between the mounting base 103 and the probe. It can withstand the vibration and external force generated when the scraper 200 is working, ensuring that the cleaning device will not be displaced or loosened during the use of the probe, so that the scraper 200 can always accurately clean the monitoring window, improving the cleaning effect and stability. At the same time, loosening the first bolts 102 makes it easy to remove the fixing ring 101 from the end of the water quality monitoring probe body 100, thereby facilitating the maintenance of the motor 305, scraper 200, etc.

[0036] It is worth noting that guide rods 202 are connected to the bottom of both sides of the scraper 200 via detachable connectors. The two sets of guide rods 202 penetrate downward through the corresponding side surface of the 7-shaped plate 201. With the setting of the guide rods 202, during the process of the scraper 200 swinging back and forth to clean the window, the guide rods 202 can limit the vertical displacement of the scraper 200, ensure that the scraper 200 maintains stable contact with the window surface, and prevent the scraper 200 from shaking up and down or detaching from the window surface when swinging, thereby improving the uniformity and effectiveness of cleaning.

[0037] Preferably, the detachable connector includes threaded posts 208 fixedly installed on the top of the guide rod 202, and threaded holes 204 are provided at the bottom of the scraper 200 at positions corresponding to the threaded posts 208. The two sets of threaded posts 208 are respectively threaded into the inner cavity of the corresponding side threaded holes 204. Through the setting of the detachable connector, the threaded connection between the threaded posts 208 and the threaded holes 204 at the bottom of the scraper 200 makes the installation and removal of the scraper 200 very convenient. When the scraper 200 is worn due to long-term use or needs cleaning, it can be easily unscrewed from the guide rod 202 for replacement or cleaning without the need for complicated disassembly and assembly of the entire cleaning device, reducing maintenance costs and difficulty, and improving the maintainability of the device.

[0038] Furthermore, a second bolt 203 is threadedly connected to the bottom of the 7-shaped plate 201. One end of the second bolt 203 is threaded through the 7-shaped plate 201, and a connecting plate 205 is fixedly connected to the other end of the second bolt 203. The top of the connecting plate 205 contacts the surface of the scraper 200. Through the arrangement of the second bolt 203 and the connecting plate 205, when the contact surface of the scraper 200 wears down, resulting in a decrease in the contact force with the monitoring window, the second bolt 203 is tightened, and one end of the second bolt 203 moves upward, pushing the scraper 200 upward, thereby increasing the contact force with the monitoring window. At the same time, it ensures that the scraper 200 can always maintain a good fit when cleaning the window, improving cleaning efficiency and quality.

[0039] Furthermore, a limiting groove 108 is formed on the inner wall of the rotating groove 107. A limiting half-ring 301 is rotatably connected to the inner cavity of the limiting groove 108. The limiting half-ring 301 is sleeved on the corresponding surface of the connecting column 300. By setting the limiting half-ring 301, the limiting half-ring 301 rotatably connected in the limiting groove 108 formed on the inner wall of the rotating groove 107 is sleeved on the surface of the connecting column 300, which can effectively limit the radial and axial displacement of the connecting column 300 during rotation. This ensures that the connecting column 300 can only rotate smoothly around its axis within the rotating groove 107, avoiding abnormal oscillation of the scraper 200 due to the unstable movement of the connecting column 300. This ensures the accuracy and stability of the scraper 200's cleaning action and improves the cleaning effect.

[0040] Preferably, a guide strip 207 is fixedly connected to the inner wall of the middle part of one side of the 7-shaped plate 201, and a guide groove 206 corresponding to the guide strip 207 is opened on one side of the scraper 200. The guide strip 207 is inserted into the inner cavity of the guide groove 206. Through the setting of the guide strip 207, the guide strip 207 on the inner wall of the middle part of one side of the 7-shaped plate 201 and the guide groove 206 on one side of the scraper 200 are interlocked. When the scraper 200 is replaced, it is convenient to position the new scraper 200, so as to facilitate the subsequent fixing of the scraper 200.

[0041] Working principle;

[0042] First, the fixing ring 101 is fitted onto the end of the water quality monitoring probe body 100 so that the swing range of the scraper 200 located on one side of the mounting base 103 can cover the monitoring window of the water quality monitoring probe body 100. Then, the first bolts 102 on both sides of the fixing ring 101 are tightened to abut against the surface of the water quality monitoring probe body 100 to prevent the fixing ring 101 from coming off. Then, the data parameters of the microcontroller 400 are set, and the motor 305 is started periodically at certain intervals.

[0043] When the time interval is reached, the microcontroller 400 controls the motor 305 to rotate. As the motor 305 starts, the power is transmitted through the connecting column 300 to the 7-shaped plate 201 fixed on one side of its surface, causing the 7-shaped plate 201 to swing back and forth. During the back and forth swing of the scraper 200, the attachments on the surface of the monitoring window can be scraped off, thereby achieving the purpose of cleaning the window.

[0044] When the scraper 200 rubs for a long time, causing wear on the contact surface of the scraper 200 and a decrease in the contact force with the monitoring window, tighten the second bolt 203. One end of the second bolt 203 moves upward, pushing the scraper 200 upward, thereby increasing the contact force with the monitoring window.

[0045] When the scraper 200 needs to be replaced, turn the second bolt 203 downwards until the connecting disc 205 at the end of the second bolt 203 sinks into the inner cavity surface of the 7-shaped plate 201. Then, rotate the two sets of guide rods 202 in sequence to unscrew the threaded post 208 at the top of the guide rod 202 out of the inner cavity of the threaded hole 204. At this time, remove the scraper 200. Then, align the guide groove 206 at one end of the new scraper 200 with the guide strip 207 installed on one side of the inner wall of the 7-shaped plate 201 to initially position the scraper 200. Then, snap it onto the surface of the guide strip 207 and rotate the guide rod 202 in sequence to screw the threaded post 208 at the top of the guide rod 202 into the inner cavity of the threaded hole 204 on the corresponding side, thereby completing the replacement of the scraper 200.
