The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage.

[0003] The utility model patent with patent announcement number CN 219084924 U discloses an online water quality monitoring device. This device needs to be immersed in water when in use, but the online water quality monitoring device has poor maneuverability and positioning performance, and cannot maneuver the monitoring area, resulting in limitations in water quality monitoring and reducing the operating range of the online water quality monitoring device.

[0004] However, the current online water quality monitoring device has the following problems: the detector of the online water quality monitoring device will be wrapped by debris in the water body when immersed in the water body for a long time, thereby reducing the accuracy of the detector. Therefore, we propose an online water quality monitoring device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an online water quality monitoring device, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: an online water quality monitoring device.

[0007] According to the above technical solution, the machine body is composed of an upper shell and a lower shell, and the lower shell is fixed to the bottom of the upper shell, a water pump is fixedly installed on the bottom surface of the inner part of the upper shell of the machine body, and a water pipe is fixedly connected to the water inlet of the water pump, and the water pipe vertically penetrates the upper shell and the lower shell of the machine body, and a sleeve is sleeved on the outer surface of the water pipe, and the sleeve downwardly penetrates the upper shell and the lower shell of the machine body, and a No. 1 sleeve gear is fixedly connected to the outer wall of the sleeve, and a motor gear is meshed on the left side of the No. 1 sleeve gear, and the left end of the motor gear is fixedly connected to the output end of the motor, and the motor is fixed to the bottom of the upper shell of the machine body, and cleaning devices for cleaning aquatic plants are arranged on the lower ends of both sides of the machine body, and a plurality of water inlet holes are opened on the part of the sleeve outside the machine body, and the sleeve The water inlet holes are on the same vertical line above and below, the water inlet hole of the casing is provided with a filter, the water pipe has water inlet holes of the same size at the same height of the water inlet holes of the casing, the water inlet holes of the water pipe are staggered above and below, a detector is provided inside the lower shell of the body, the detector is fixedly installed at the center position of the space of the lower shell of the body through a bracket, a check valve is fixedly installed at the lower end of the back of the body, the check valve runs through the outer wall of the body, four connecting parts are fixedly installed at the four corners of the top of the body, a solar panel is fixedly installed on the top of the connecting part, a battery is fixedly installed on the upper surface of the bottom plate of the upper shell of the body, the battery is located behind the water pump, an annular blade is slidably installed on the outer wall of the lower section of the casing, and a fixing rod is fixedly installed on the outer wall of the annular blade. A connecting rod is hinged on the upper end of the fixed rod, and a rotating wheel is hinged on one end of the connecting rod away from the fixed rod. A connecting rod gear is fixedly installed on the rear side of the rotating wheel. The body is divided into an upper shell and a lower shell. The upper shell is used to install equipment, and the lower shell is used to store water. When the water pump pumps water, the water sample to be tested is extracted through the water pipe, and the water is pumped to the lower shell for storage. When the lower shell is kept full of water, the excess water sample will be discharged from the body through the check valve. When the water pump pumps water, the motor drives the motor gear to rotate, and the motor gear drives the No. 1 casing gear to rotate, and the No. 1 casing gear drives the casing to rotate. The water inlet hole set at the lower end of the casing will coincide with the water inlet hole of the water pipe during the rotation. Since the water inlet hole of the water pipe is staggered, there is always and only one water inlet hole of the casing that coincides with the water pipe during the rotation. The water inlet holes of the casing completely overlap, and the water inlet holes of different depths of the casing will overlap with the water inlet holes of the water pipe in turn. When the casing rotates, it will drive the No. 2 casing gear to rotate, and the No. 2 casing gear will drive the rotating wheel to rotate, and the rotating wheel will drive the connecting rod to rotate. Since the connecting rod is hinged to the fixed rod and the fixed rod is slidably installed on the casing by an annular blade, the rotation of the connecting rod will drive the fixed rod to reciprocate up and down, and the fixed rod drives the annular blade to reciprocate up and down. During the reciprocating motion, the annular blade can scrape off the debris on the surface of the filter screen of the casing water inlet hole, so that the filter screen can continuously filter impurities in the water and keep the water inlet unobstructed, so that the water sample in the machine body is relatively clean, which avoids the detector being wrapped by impurities in the water and affecting the detection data, thereby achieving the effect of protecting the detector and improving the detection accuracy.

[0008] According to the above technical scheme, the cleaning device includes a No. 2 sleeve gear, the No. 2 sleeve gear is meshed with one side of the connecting rod gear, and the No. 2 sleeve gear is fixedly connected to the outer wall of the sleeve, and the left and right sides of the No. 2 sleeve gear are respectively meshed with a scraper gear, and the scraper gear is fixedly connected to a rotating shaft at one end away from the sleeve, and the rotating shaft passes through the outer wall of the body, and two scrapers are fixedly connected to the end of the rotating shaft away from the sleeve, and a blade is slidably installed on the inner side of the scraper, and a fixing part is fixedly connected to the middle part of the blade, and a crank is hinged in the middle of the fixing part, and a fixing spring is fixedly connected to the end of the crank away from the fixing part, and the fixing spring is fixedly connected to the outer wall of the scraper at one end away from the crank, and a plurality of convex balls are fixedly installed on the side outer wall of the body, and the convex balls are located on the movement trajectory of the crank. When the No. 2 sleeve gear rotates, it drives the scraper gears on both sides to rotate, the scraper gears drive the rotating shaft to rotate, and the rotating shaft drives the scraper to rotate. During the rotation of the scraper, the crank will contact the convex ball on its movement trajectory, and the crank will be moved away from the machine body by the convex ball, thereby pushing the blade. When the crank passes the convex ball, it will rebound and reset through the fixed spring to pull back the blade. Every time the crank contacts the convex ball, the blade will reciprocate on the scraper surface to cut off the debris attached to the scraper surface.

The water inlet holes of the sleeve 6 are provided with a filter screen, and the water pipe 13 is provided with water inlet holes of the same size at the same height as the water inlet holes of the sleeve 6. The water inlet holes of the water pipe 13 are staggered up and down. A detector 18 is provided inside the lower shell of the body 1, and the detector 18 is fixedly installed in the space of the lower shell of the body 1 through a bracket. At the center position, a check valve 19 is fixedly installed at the lower end of the back of the body 1, and the check valve 19 runs through the outer wall of the body 1. Four connecting pieces 9 are fixedly installed at the four corners of the top of the body 1, and a solar panel 10 is fixedly installed on the top of the connecting piece 9. A battery 11 is fixedly installed on the upper surface of the bottom plate of the upper shell of the body 1, and the battery 11 is located behind the water pump 12. An annular blade 5 is slidably installed on the outer wall of the lower section of the sleeve 6, and a fixing rod 4 is fixedly installed on the outer wall of the annular blade 5.

A connecting rod gear 17 is fixedly installed on the rear side of the rotating wheel 2. Through the coordinated work of the machine body 1, the water pump 12, the water pipe 13, the sleeve 6, the check valve 19, the motor 14, the motor gear 15, and the No. 1 sleeve gear 16, the detector 18 can detect water samples at different depths of the water body, and through the No. 2 sleeve gear 78, the wheel 2, the connecting rod 3, the fixing rod 4, and the annular blade 5, the filter net on the surface of the water inlet hole of the sleeve 6 can continuously filter impurities in the water and keep the water inlet unobstructed, so that the water sample in the machine body 1 is relatively clean, and the detector 18 is prevented from being wrapped by impurities in the water and affecting the detection data, thereby achieving the effect of protecting the detector 18 and improving the detection accuracy.

[0023] The cleaning device 7 includes a No. 2 sleeve gear 78, which is meshed with one side of the connecting rod gear 17 and fixedly connected to the outer wall of the sleeve 6. A scraper gear 77 is meshed on the left and right sides of the No. 2 sleeve gear 78 respectively. The scraper gear 77 is fixedly connected to a rotating shaft 71 at one end away from the sleeve 6. The rotating shaft 71 penetrates the outer wall of the body 1, and two scrapers 72 are fixedly connected to the end of the rotating shaft 71 away from the sleeve 6. A blade 73 is slidably installed on the inner side of the scraper 72, and a fixing member 76 is fixedly connected to the middle part of the blade 73. A crank 75 is hinged at the middle part of the fixing member 76. A fixing spring 74 is fixedly connected to the end of the crank 75 away from the fixing member 76. The fixing spring 74 is fixedly connected to the outer wall of the scraper 72 at one end away from the crank 75. A plurality of convex balls 8 are fixedly installed on the outer wall of the side of the body 1, and the convex balls 8 are located on the movement trajectory of the crank 75. Through the cooperation of the second sleeve gear 78, the scraper gear 77, the rotating shaft 71, and the scraper 72, when the scrapers 72 on both sides of the body 1 rotate, the floating debris in the water around the body 1 can be pushed away to prevent the body 1 from being entangled by the debris in the water. Through the arrangement of the convex ball 8, the crank 75, the fixed spring 74, and the blade 73, the scraper 72 can continuously remove the debris attached to the surface by the blade 73 during the movement, so that the water quality online monitoring device can continuously clean the surrounding water debris.

[0024] When in use, the body 1 is divided into an upper shell and a lower shell. The upper shell is used to install equipment, and the lower shell is used to store water. When the water pump 12 pumps water, the water sample to be tested is extracted through the water pipe 13, and the water is pumped to the lower shell for storage. When the lower shell is kept full of water, the excess water sample will be discharged from the body 1 through the check valve 19. When the water pump 12 pumps water, the motor 14 drives the motor gear 15 to rotate, and the motor gear 15 drives the No. 1 sleeve gear 16 to rotate, and the No. 1 sleeve gear 16 drives the sleeve 6 to rotate. The water inlet hole set at the lower end of the sleeve 6 will coincide with the water inlet hole of the water pipe 13 during the rotation process. Since the water inlet hole of the water pipe 13 is staggered, the sleeve 6 always has and only has one water inlet hole that completely coincides with the water inlet hole of the water pipe 13 during the rotation process. The water inlet holes of the sleeve 6 at different depths will coincide with the water inlet holes of the water pipe 13 in turn, so that the water pump 12 can pump water of different depths, and the water samples in the lower shell of the body 1 pass through water samples of different depths. After mixing, various data of the water body can be detected more accurately. Since the lower shell of the body 1 will exert a certain sinking force after storing water, the body 1 will float stably on the water surface to avoid being overturned by wind and waves. When the sleeve 6 rotates, it will drive the No. 2 sleeve gear 78 to rotate, and the No. 2 sleeve gear 78 will drive the runner 2 to rotate, and the runner 2 will drive the connecting rod 3 to rotate. Since the connecting rod 3 is hinged with the fixed rod 4 and the fixed rod 4 is slidably installed on the sleeve 6 by the annular blade 5, the rotation of the connecting rod 3 will drive the fixed rod 4 to reciprocate up and down, and the fixed rod 4 drives the annular blade 5 to reciprocate up and down. During the reciprocating motion, the annular blade 5 can scrape off the debris on the surface of the filter screen of the water inlet hole of the sleeve 6, so that the filter screen can continuously filter impurities in the water and keep the water inlet unobstructed, so that the water sample in the body 1 is relatively clean, and the detector 18 is prevented from being wrapped by impurities in the water, affecting the detection data, thereby achieving the effect of protecting the detector 18 and improving the detection accuracy.

[0025] When the second sleeve gear 78 rotates, it drives the scraper gears 77 on both sides to rotate, and the scraper gears 77 drive the rotating shaft 71 to rotate, and the rotating shaft 71 drives the scraper 72 to rotate. During the rotation of the scraper 72, the crank 75 will contact the convex ball 8 on its movement trajectory, and the crank 75 is moved away from the body 1 by the convex ball 8, thereby pushing the blade 73. When the crank 75 passes the convex ball 8, it will rebound and reset through the fixed spring 74 to pull back the blade 73. Every time the crank 75 contacts the convex ball 8 once, the blade 73 will reciprocate on the surface of the scraper 72 to remove the debris attached to the surface of the scraper 72. When the scraper 72 on both sides of the body 1 rotates, the debris floating in the water around the body 1 can be pushed away to prevent the body 1 from being entangled by the debris in the water. At the same time, the scraper 72 will continuously remove the debris attached to the surface by the blade 73 during the movement, so that the water quality online monitoring device can continuously clean the debris in the surrounding water.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
