[0025] See also Figure 1 - Figure 7 As shown, a surface water quality monitoring device includes a device body 1, a filter sampling component 20 and a hose 22; the top of the filter sampling component 20 is threadedly connected to an end cap 21, the bottom end of the hose 22 is sleeved inside a fixed sleeve 23, and a clamping mechanism is provided inside the end cap 21. The clamping mechanism includes a long groove 24, which is opened at the bottom end of the fixed sleeve 23. A rotating rod 25 is rotatably connected to the long groove 24. The width and length of the rotating rod 25 are both adapted to the long groove 24. The top of the rotating rod 25 abuts against a slide groove 26, which is opened at the bottom end of the end cap 21. A fixing ring 3 is welded and fixed to the fixed sleeve 23. 2. The fixing ring 32 is located in the middle of the fixing sleeve 23. The bottom end of the fixing ring 32 contacts the support ring 33. The bottom end of the support ring 33 is fixedly connected to two groups of first springs 34. The bottom end of the first spring 34 is fixedly connected to the clamping block 35. The clamping block 35 is rotatably connected to the inside of the clamping slot 40. The clamping block 35 is designed in an I-shape. The clamping slot 40 is provided on the fixing seat 31. The clamping slot 40 is designed in a T-shape so that the clamping block 35 will not separate from the clamping slot 40 during rotation. The fixing seat 31 is welded and fixed to the top of the end cover 21. A through hole 39 is provided on the end cover 21. Two groups of stoppers 36 are welded and fixed to the bottom end of the end cover 21.

[0026] During operation, a surface water quality monitoring device of the above technology, in which the filtering sampling component is placed under the water surface for a long time, inevitably needs to be cleaned regularly to ensure its normal use, and the sampling tube is fixedly sleeved on the filtering sampling component. When cleaning and installing, the sampling tube needs to be disassembled and installed, which is relatively time-consuming. The structural design of the locking mechanism realizes the function of facilitating the removal of the hose 22 from the filtering sampling component 20. When the hose 22 is removed from the filtering sampling component 20 to clean the inside of the filtering sampling component 20, the fixing sleeve 23 is first installed downward, and then the fixing sleeve 23 is rotated. When the fixing sleeve 23 is rotated, the two sets of rotating rods 25 will also rotate, and will contact the two sets of stoppers 36 during rotation, and the stoppers 36 will resist the rotating rods 25. Then, the rotating rod 25 is rotated on the long groove 24 to be received in the long groove 24. At this time, the fixing sleeve 23 can be pulled out by pulling the fixing sleeve 23 upward to separate the hose 22 and the filter sampling component 20, so as to facilitate cleaning of the filter sampling component 20 and the hose 22. A rounded corner is provided on the rotating rod 25 so that it can rotate smoothly when it abuts against the block 36. The support ring 33 is supported by two groups of first springs 34 at the bottom and the first spring 34 provides an upward thrust for the fixing ring 32 to ensure the fixing effect of the rotating rod 25 and the bottom end of the end cover 21. The block 35 slides inside the slot 40. The size of the through hole 39 is adapted to the fixing sleeve 23 to facilitate the normal insertion of the fixing sleeve 23.

[0027] Furthermore, a cavity 27 is formed inside the top of the rotating rod 25, and a magnetic column 28 is inserted into the cavity 27. The magnetic column 28 is designed in a T-shape to prevent the top of the magnetic column 28 from slipping out of the cavity 27. The top of the magnetic column 28 is attracted to the magnet 30, and the magnet 30 is glued and fixed to the inner wall of the slot 29. The slot 29 is formed at the bottom end of the end cover 21.

[0028] During operation, through the structural design of the magnetic column 28, the slot 29 and the magnet 30, when the rotating rod 25 and the slide groove 26 are in contact, the magnet 30 will be attracted to the magnetic column 28 inserted inside the cavity 27, thereby inserting the top end of the magnetic column 28 into the inside of the slot 29. The contact between the magnetic column 28 and the inner wall of the slot 29 makes the rotating rod 25 more stable when fixed.

[0029] Furthermore, a groove 38 is formed on the inner wall of the through hole 39, and a gasket 37 is glued and fixed to the groove 38, so that the gasket 37 and the fixing sleeve 23 maintain contact;

[0030] During operation, the sealing between the through hole 39 and the fixing sleeve 23 is improved by the contact between the groove 38 and the fixing sleeve 23 .

[0031] Furthermore, a traction rope 41 is glued and fixed to the top of the end cover 21, the left side of the traction rope 41 is fixed to the traction wheel 46, and the rear end of the traction wheel 46 is fixedly connected to the motor 43;

[0032] During operation, when the filter sampling component 20 needs to be taken out for cleaning, the traction wheel 46 is driven to rotate by the motor 43, so that the filter sampling component 20 can be pulled out by the traction rope 41, so as to facilitate the removal of the filter sampling component 20 from underwater.

[0033] Furthermore, the bottom ends of the traction wheels 46 are welded and fixed inside the placement slot 44. The placement slot 44 is rectangular in design and is located on the left side of the device body 1. A cabinet door 42 is provided on the placement slot 44.

[0034] During operation, a small hole corresponding to the traction rope 41 is opened on the cabinet door 42, and a placement slot 44 is opened inside the device body 1 for easy storage.

[0035] Furthermore, a scraping assembly is provided on the cabinet door 42, and the scraping assembly includes a fixed block 52, which is fixedly connected to the cabinet door 42, and a second spring 51 and a plurality of scraping blocks 53 are fixedly connected to the interior of the fixed block 52, and a telescopic block 50 is fixed to the second spring 51 by welding;

[0036] During operation, the scraping block 53 contacts the surface of the traction rope 41, so that in the process of retracting the traction rope 41, the scraping block 53 can scrape off the debris on the surface of the traction rope 41 to ensure the tidiness of the traction rope 41. At the same time, by pushing the telescopic block 50 to move toward the inside of the fixed block 52, the scraping block 53 can be exposed to facilitate cleaning of the scraping block 53.

[0037] Working principle: In the surface water quality monitoring device of the above technology, the filter sampling component is placed under the water surface for a long time, and it is inevitable to clean it regularly to ensure its normal use, and the sampling tube is fixedly sleeved on the filter sampling component. When cleaning and installing, the sampling tube needs to be disassembled and installed, which is relatively time-consuming. The structural design of the locking mechanism is used to facilitate the removal of the hose 22 from the filter sampling component 20. When the hose 22 is removed from the filter sampling component 20 to clean the inside of the filter sampling component 20, first install the fixing sleeve 23 downward, and then rotate the fixing sleeve 23. When the fixing sleeve 23 is rotated, the two sets of rotating rods 25 will also rotate, and will contact the two sets of stoppers 36 during rotation, and the stoppers 36 will resist the rotating rods 25. Then, the rotating rod 25 is rotated on the long groove 24 to be received in the long groove 24. At this time, the fixing sleeve 23 can be pulled out by pulling the fixing sleeve 23 upward to separate the hose 22 and the filter sampling component 20, so as to facilitate cleaning of the filter sampling component 20 and the hose 22. A rounded corner is provided on the rotating rod 25 so that it can rotate smoothly when it abuts against the block 36. The support ring 33 is supported by two groups of first springs 34 at the bottom and the first spring 34 provides an upward thrust for the fixing ring 32 to ensure the fixing effect of the rotating rod 25 and the bottom end of the end cover 21. The block 35 slides inside the slot 40. The size of the through hole 39 is adapted to the fixing sleeve 23 to facilitate the normal insertion of the fixing sleeve 23.
