Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, specifically a 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 to evaluate 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 types of industrial wastewater.

[0003] Traditional water quality monitoring sampling devices are convenient for sampling operations at corresponding heights. However, if negative pressure suction sampling is used, impurities are easily accumulated in the negative pressure tube, resulting in inaccurate samples, affecting monitoring results, and making cleaning inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a water quality monitoring and sampling device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water quality monitoring sampling device, comprising a sampling component, a support component, and a closing component. The sampling component includes a base, a support cylinder, a sampling cylinder, a hinge seat, and a hinge cover. A support cylinder with an upper opening is mounted on the base. The hinge seat is located above one end of the support cylinder. The hinge cover is hinged to the hinge seat and is adapted to the upper opening of the support cylinder. A sampling cylinder is also disposed inside the support cylinder. The base is further provided with a mechanism for closing the hinge cover. The closing assembly includes a spring, a support tube, a support rod, a baffle, and a flange. The spring is sleeved on the support tube. A baffle is provided on the outer side of the support rod. The upper and lower ends of the spring are respectively connected to the base and the baffle. The lower part of the support rod is slidably connected to the support tube. The flange is also provided on the hinge cover. The upper part of the support rod contacts the flange. The support assembly includes a connecting rod and a pull rope. The connecting rod is provided on the base. The pull rope is connected to the end of the hinge cover away from the flange.

[0008] To facilitate stable operation of the support rod, this utility model is improved by providing an arc-shaped block below the flange and a groove that matches the arc-shaped block above the support rod.

[0009] Preferably, a buckle for securing the pull rope is provided above the connecting rod, and the buckle is C-shaped.

[0010] To facilitate cleaning of the sampling cylinder, this utility model is improved by making the sampling cylinder and the support cylinder detachably connected.

[0011] Preferably, a first magnetic absorbing sheet is embedded in the bottom wall of the sampling cylinder, and a second magnetic absorbing sheet adapted to the first magnetic absorbing sheet is embedded in the bottom wall of the support cylinder.

[0012] Preferably, the buckle is elastic.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a water quality monitoring and sampling device, which has the following beneficial effects:

[0015] This water quality monitoring and sampling device involves placing a sampling tube inside a support cylinder, closing the hinged cover using a closure assembly, and then using a connecting rod to lower the base into the water at the corresponding position. A pull rope pulls the hinged cover, which has an arc-shaped block on its flange that presses against the support rod, thus opening the cover and allowing water to enter the sampling tube at the corresponding position. Releasing the pull rope closes the hinged cover, ensuring accurate sampling. The sampling tube and support cylinder are detachably connected for easy disassembly, cleaning, and use.

[0021] 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.

[0022] Please see Figure 1-4A water quality monitoring sampling device includes a sampling assembly, a support assembly, and a closing assembly. The sampling assembly includes a base 1, a support cylinder 2, a sampling cylinder 3, a hinge seat 4, and a hinge cover 5. The base 1 has a support cylinder 2 with an upper opening. The hinge seat 4 is located above one end of the support cylinder 2. The hinge cover 5 is hinged to the hinge seat 4 and is adapted to the upper opening of the support cylinder 2. The support cylinder 2 also contains the sampling cylinder 3. The base 1 also has a closing assembly for closing the hinge cover 5. The closing assembly includes a spring 6 and a support... The support assembly includes a support tube 7, a support rod 8, a baffle 9, and a flange 10. A spring 6 is sleeved on the support tube 7. A baffle 9 is provided on the outer side of the support rod 8. The upper and lower ends of the spring 6 are respectively connected to the base 1 and the baffle 9. The lower part of the support rod 8 is slidably connected to the support tube 7. The flange 10 is also provided on the hinge cover 5. The upper part of the support rod 8 contacts the flange 10. The support assembly includes a connecting rod 12 and a pull rope 11. The connecting rod 12 is provided on the base 1. The pull rope 11 is connected to the end of the hinge cover 5 away from the flange 10.

[0023] In actual use, firstly, the hinge cover 5 is rotated by pulling the rope 11. Under the support of the hinge seat 4 of the support cylinder 2, the flange 10 of the hinge cover 5 presses down on the support rod 8. The baffle 9 of the support rod 8 then presses down on the spring 6. The support tube 7 and the support cylinder 2 are both set on the base plate. The sampling tube 3 is placed into the support cylinder 2. The rope 11 is no longer pulled. The closing assembly makes the hinge cover 5 and the support cylinder 2 stably close. The base 1 is sent into the corresponding position through the connecting rod 12. The rope 11 is pulled again, and water enters the sampling tube 3 of the support cylinder 2. After sampling is completed, the rope 11 is no longer pulled. The closing assembly makes the hinge cover 5 return to its original position. The base 1 is taken out through the connecting rod 12, and the sampling is completed.

[0024] In this embodiment, if the flange 10 is used to hold the support rod 8, it is difficult to open the hinge cover 5. Therefore, an arc-shaped block 13 is provided below the flange 10, and a groove that matches the arc-shaped block 13 is provided above the support rod 8 to ensure the stability of the hinge cover 5 when opening and closing.

[0025] In actual use, a buckle 14 for locking the pull rope 11 is provided above the connecting rod 12. The buckle 14 is C-shaped and elastic to facilitate cable bundling and prevent the end of the pull rope 11 from being pulled accidentally.

[0026] In this embodiment, in order to facilitate the cleaning of the sampling tube 3, the sampling tube 3 and the support tube 2 are detachably connected. In actual use, it is necessary to ensure the stability of the connection between the sampling tube 3 and the support tube 2. For this purpose, a first magnetic absorbing piece 15 is embedded in the bottom wall of the sampling tube 3, and a second magnetic absorbing piece that matches the first magnetic absorbing piece 15 is embedded in the bottom wall of the support tube 2.
