Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to a surface water quality monitoring and sampling device. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality status. Sampling equipment is needed to take samples of water from the water source in order to monitor the sample water source.

[0003] When sampling surface water, the commonly used sampling equipment is to insert a straight pipe directly into the water source, allowing water to flow into the pipe, and then sealing the pipe to complete the sampling. This method does not involve stratified sampling of the water source, which can easily lead to mixing of water at different depths during transportation, affecting the accuracy of water quality monitoring. Therefore, we propose a surface water quality monitoring sampling device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a surface water quality monitoring and sampling device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface water quality monitoring and sampling device, comprising a float, a first mounting frame fixedly connected to the top of the float, a winding roller rotatably connected inside the first mounting frame via a rotating shaft, a guide cable wound around the outside of the winding roller, one end of the guide cable fixedly connected to the outside of the winding roller, a top frame fixedly connected to one end of the guide cable, a mounting base threadedly connected inside the top frame, a drive shaft rotatably connected inside the mounting base via a bearing, a rotating sleeve fixedly connected to the outside of the drive shaft, an outer fixing frame threadedly connected inside the mounting base, a collection bucket fixedly connected inside the outer fixing frame, an internal groove formed inside the collection bucket, and a rotating sleeve rotatably connected inside the internal groove.

[0006] Preferably, the collection bucket has three collection slots inside, and two corresponding first feed inlets are opened inside the collection bucket on one side of the collection slots. The rotating sleeve has three sets of second feed slots inside, and the positions of the second feed slots are staggered. The transmission shaft is driven to rotate by the second servo motor, thereby driving the rotating sleeve to rotate inside the inner slots, thereby adjusting the position of multiple sets of second feed slots. When the second feed slot at the corresponding angle coincides with the corresponding first feed inlet, the water sample enters the interior of the corresponding collection slot, so that water samples at different depths can be sampled as needed.

[0007] Preferably, an electromechanical box is fixedly installed inside the mounting base, and a second servo motor is fixedly installed inside the electromechanical box. The output end of the second servo motor is fixedly connected to the transmission shaft via a coupling.

[0008] Preferably, a second mounting bracket is fixedly connected to the top of the float plate. Inside the second mounting bracket, two corresponding rotating shafts are rotatably connected via bearings. Guide wheels are fixedly connected to the outer side of the rotating shafts. The two guide wheels cooperate with the guide cable, and the guide cable can be guided by the cooperation between the rotating shafts and the guide wheels.

[0009] Preferably, the second mounting frame has an I-shaped groove inside, and a threaded rod is rotatably connected inside the I-shaped groove via a shaft. An I-shaped slider is slidably connected inside the I-shaped groove, and the threaded rod passes through the I-shaped slider and cooperates with it. A guide sleeve is fixedly connected to the top of the I-shaped slider, and the guide sleeve cooperates with the guide cable. A third servo motor can drive the threaded rod to rotate, thereby causing the I-shaped slider to slide inside the I-shaped groove, which in turn causes the guide sleeve to move at the top of the second mounting frame, thus guiding the guide cable during winding and preventing knotting during winding.

[0010] Preferably, an electromechanical box is fixedly installed inside the second mounting bracket, and a third servo motor is fixedly installed inside the electromechanical box. The output end of the third servo motor is fixedly connected to a threaded rod via a coupling.

[0011] Preferably, an electromechanical box is fixedly installed on the outside of the first mounting frame, and a first servo motor is fixedly installed inside the electromechanical box. The output end of the first servo motor is fixedly connected to the take-up roller through a coupling, and a through groove is opened inside the float plate.

[0012] This utility model provides a surface water quality monitoring and sampling device, which has the following beneficial effects: 1. This surface water quality monitoring and sampling equipment uses a second servo motor to drive the transmission shaft to rotate, which in turn drives the rotating sleeve to rotate inside the inner tank. This adjusts the position of multiple sets of second feed troughs. When the second feed trough at the corresponding angle coincides with the corresponding first feed inlet, the water sample enters the corresponding collection tank. This allows for sampling of water samples at different depths as needed, improving the practicality of the surface water quality monitoring and sampling equipment.

[0013] 2. The surface water quality monitoring and sampling equipment uses a third servo motor to drive the threaded rod to rotate, which in turn drives the I-beam slider to slide inside the I-beam groove. This, in turn, moves the guide sleeve to the top of the second mounting frame, thus guiding the guide cable during winding and preventing knots. This improves the practicality of the surface water quality monitoring and sampling equipment. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a surface water quality monitoring and sampling device, including a float 1, a first mounting frame 2 fixedly connected to the top of the float 1, a winding roller 3 rotatably connected inside the first mounting frame 2 via a rotating shaft, a guide cable 5 wound around the outside of the winding roller 3, one end of the guide cable 5 fixedly connected to the outside of the winding roller 3, a top frame 9 fixedly connected to one end of the guide cable 5, a mounting base 10 threadedly connected inside the top frame 9, a drive shaft 18 rotatably connected inside the mounting base 10 via a bearing, a rotating sleeve 16 fixedly connected to the outside of the drive shaft 18, an outer fixing frame 11 threadedly connected inside the mounting base 10, a collection bucket 12 fixedly connected inside the outer fixing frame 11, an internal groove 15 opened inside the collection bucket 12, and a rotating sleeve 16 rotatably connected inside the internal groove 15; The collection bucket 12 has three collection slots 13 inside. There are two corresponding first feed inlets 14 inside the collection bucket 12 and on one side of the collection slots 13. The rotating sleeve 16 has three sets of second feed slots 17 inside. The positions of the second feed slots 17 are staggered. The second servo motor 19 drives the transmission shaft 18 to rotate, thereby driving the rotating sleeve 16 to rotate inside the inner slot 15, thereby adjusting the position of multiple sets of second feed slots 17. When the second feed slot 17 at the corresponding angle coincides with the corresponding first feed inlet 14, the water sample enters the interior of the corresponding collection slot 13. Thus, water samples at different depths can be sampled according to the needs. The mounting base 10 has a fixed electromechanical box installed inside, and the electromechanical box has a fixed second servo motor 19 installed inside. The output end of the second servo motor 19 is fixedly connected to the transmission shaft 18 through a coupling. The top of the float 1 is fixedly connected to a second mounting bracket 6. Inside the second mounting bracket 6, two corresponding rotating shafts 7 are rotatably connected via bearings. Guide wheels 8 are fixedly connected to the outside of the rotating shafts 7. The two guide wheels 8 cooperate with the guide cable 5. The guide cable 5 can be guided by the cooperation of the rotating shafts 7 and the guide wheels 8. The second mounting bracket 6 has an I-shaped groove 20 inside. A threaded rod 21 is rotatably connected to the inside of the I-shaped groove 20 via a shaft. An I-shaped slider 22 is slidably connected inside the I-shaped groove 20. The threaded rod 21 passes through the I-shaped slider 22 and cooperates with it. A guide sleeve 23 is fixedly connected to the top of the I-shaped slider 22. The guide sleeve 23 cooperates with the guide cable 5. The threaded rod 21 can be rotated by the third servo motor 24, thereby causing the I-shaped slider 22 to slide inside the I-shaped groove 20, thereby causing the guide sleeve 23 to move at the top of the second mounting bracket 6. This guides the guide cable 5 when it is being wound up, preventing it from getting knotted. The second mounting bracket 6 has an electromechanical box fixedly installed inside, and the electromechanical box has a third servo motor 24 fixedly installed inside. The output end of the third servo motor 24 is fixedly connected to the threaded rod 21 through a coupling. An electromechanical box is fixedly installed on the outside of the first mounting bracket 2. The first servo motor 4 is fixedly installed inside the electromechanical box. The output end of the first servo motor 4 is fixedly connected to the take-up roller 3 through a coupling. A through groove 25 is opened inside the float plate 1.

[0018] In summary, this surface water quality monitoring and sampling equipment, during use, involves floating the float 1 on the water surface and fixing it to the shore with bolts. Then, all mechanisms are powered on, and the first servo motor 4 is activated via a remote controller to rotate the winding roller 3, thereby allowing the guide cable 5 to be extended and retracted. This allows the outer fixing frame 11 to be immersed in the water through the through groove 25. The immersion depth of the outer fixing frame 11 can be adjusted by the length of the guide cable 5. The scale markings on the guide cable 5 facilitate observation of the extension length and immersion depth of the outer fixing frame 11. When the outer fixing frame 11 reaches the corresponding depth, the second servo motor 19 is activated via the remote controller to rotate the drive shaft 18, thereby causing the rotating sleeve 16 to rotate inside the internal groove 15. This adjusts the position of multiple sets of second feed troughs 17. When the second feed trough 17 at the corresponding angle coincides with the corresponding first feed inlet 14, the water sample enters the corresponding collection tank 13. Then, the rotating sleeve 16 is rotated again to feed the first feed... The opening 14 is sealed to allow for sampling of water at different depths as needed. The second servo motor 19 is a waterproof servo motor. The encoder inside the second servo motor 19 facilitates precise control of the rotation angle of the rotating sleeve 16, thereby enabling precise control of the second feed trough 17. Existing sealing technologies such as sealing gaskets are used at all sealing connections. A water quality monitor is installed at the bottom of the float 1 to monitor the water quality close to the water surface at all times. When the first servo motor 4 is started to drive the winding roller 3 to wind up the guide cable 5 and lift the outer fixing frame 11 and the collection bucket 12 out of the water, the third servo motor 24 is started by the remote controller to reciprocate, thereby driving the threaded rod 21 to reciprocate, which in turn drives the I-shaped slider 22 to reciprocate within the I-shaped groove 20, thereby driving the guide sleeve 23 to reciprocate, thus guiding the guide cable 5 and preventing the guide cable 5 from tangling during winding. The guide sleeve 23 can scrape off the debris adhering to the outside of the guide cable 5.
