Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a sampling device for water quality monitoring. 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. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various industrial wastewater. Water quality monitoring requires sampling at different depths, so sampling equipment is needed.

[0003] Referring to the patent document publication number, a water quality monitoring sampling device is described. This device can continuously sample and test water quality at different depths without replacing the sampling device, and can control the sampling bottle through a solenoid valve. This improves the efficiency and effectiveness of water quality sampling at different depths, thus enhancing its practicality. The device includes two sets of sampling bottles and a traction device, as well as a fixed rod, two sets of mounting seats, two sets of first sliders, two sets of solenoid valves, two sets of screws, two sets of rotating nuts, two sets of arc-shaped clamps, and a buffer mechanism. Both ends of the fixed rod are connected to one end of the mounting seat. Each of the two sets of mounting seats has a sliding groove at one end of its working cavity. The two sets of first sliders are slidably connected to the sliding grooves. The other ends of the two sets of first sliders are connected to one end of the sampling bottle. The left side of one set of mounting seats and the right side of one set of mounting seats are threadedly connected to the screws.

[0004] While the above-mentioned method can sample water, it still has some shortcomings. For example, it is difficult to sample water at different depths at the same time, which takes a long time to sample water at different depths. Therefore, a water quality monitoring sampling device is proposed. Utility Model Content

[0007] As a further description of the above technical solution:

[0008] A partition is fixedly connected to the inner wall of the square tube. Two sliding grooves are opened on the upper surface of the partition, and the two upright plates are respectively located inside the two sliding grooves.

[0009] As a further description of the above technical solution:

[0010] The inside of the square tube is provided with a limiting block, and the upper surface of the limiting block is fixedly connected to the bottom surface of the two upright plates.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0014] The outer surface of the motor is covered with a protective shell, and the bottom surface of the protective shell is fixedly connected to the upper surface of the horizontal plate.

[0015] As a further description of the above technical solution:

[0016] Each of the bends is slidably connected to a sealing head on its right end, and a pull rope is fixedly connected to the right side of each sealing head. The left end of each pull rope is fixedly connected to the right side of the square tube.

[0017] This utility model has the following beneficial effects:

[0018] 1. Compared with the prior art, this water quality monitoring sampling device has a motor that can provide power to the threaded rod, which in turn makes the threaded rod work with the threaded ring to move the vertical plate up and down. The vertical plate can push the connecting rod up and down through the push plate, so that the piston plate slides inside the bend, thereby sampling water at different depths at the same time, thereby reducing the time required to sample water at different depths and improving the water sampling efficiency.

[0019] 2. Compared with the prior art, this water quality monitoring sampling device has a sealing head to prevent water from entering the bend when the device is inserted underwater. Furthermore, by moving the piston downward, the air pressure inside the bend can be increased, thereby opening the sealing head after reaching the specified depth. This prevents water from entering the bend before reaching the specified depth, ensuring the accuracy of water quality monitoring. Attached Figure Description

[0028] In this embodiment, a fixing seat 19 is fixedly connected to the upper surface of each push plate 18. The left side of each fixing seat 19 is fixedly connected to the right side of one of the upright plates 11. The fixing seat 19 can reinforce the push plate 18, increase the stability of the push plate 18, and prevent the push plate 18 from falling off. A limiting block 13 is provided inside the square tube 3. The upper surface of the limiting block 13 is fixedly connected to the bottom surface of the two upright plates 11. The limiting block 13 can limit the upright plates 11 and prevent them from shaking during the up and down movement. A partition 12 is fixedly connected to the inner wall of the square tube 3. Two sliding grooves 15 are opened on the upper surface of the partition 12. The two upright plates 11 are respectively located inside the two sliding grooves 15. The partition 12 and the sliding grooves 15 can position the upright plates 11 and prevent them from sliding during use.

[0029] In this embodiment, a sealing head 5 is slidably connected to the right end of each bend 6, a pull rope 7 is fixedly connected to the right side of each sealing head 5, and the left end of each pull rope 7 is fixedly connected to the right side of the square tube 3.

A protective shell 2 is provided on the outer surface of the motor 8, and the bottom surface of the protective shell 2 is fixedly connected to the upper surface of the horizontal plate 1. By providing the protective shell 2, the motor 8 can be protected to avoid damage caused by collision.

[0030] Working principle: When in use, the device is inserted into the water to reach the designated position. Then, the motor 8 is started, which drives the threaded rod 10 to rotate. The threaded rod 10 drives the threaded ring 9 to rotate, and the threaded ring 9 pushes the vertical plate 11 to move downward. The vertical plate 11 pushes the connecting rod 17 downward through the push plate 18, which increases the air pressure inside the bend 6, forcing the sealing head 5 out of the bend 6 and opening the bend 6. Then, the motor 8 is controlled to reverse, causing the vertical plate 11 to pull the push plate 18 and the connecting rod 17 upward. The connecting rod 17 pulls the piston 16 upward, drawing water. This allows the two bends 6 to sample water at different depths.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
