Description
Technical Field
[0001] The utility model relates to the technical field of water quality sampling devices, in particular to an automatic water quality sampling device. Background Art
[0002] Perfluorinated compounds (PFCs) refer to a class of fluorinated organic compounds in which all hydrogen atoms connected to carbon atoms in the compound molecules are replaced by fluorine atoms and connected to various hydrophilic groups. Typical examples include perfluorinated carboxylic acids, perfluorinated sulfonic acids, perfluorobutyric acid, and perfluorohexanoic acid. The CF bonds in the molecules of these compounds are very stable, giving them unique properties such as high surface activity, acid resistance, heat resistance, lipophobicity, and hydrophobicity. These properties also make PFCs very widely used. They can be used in textile coatings, detergents, non-stick coatings, foam fire extinguishers, and food packaging in commerce; in industry, they can be used as surfactants, polymers, pesticides, and lubricants. Because of the wide application of PFCs, they are easily transmitted to the water environment through various channels. Perfluorinated compounds have the characteristics of potential toxicity, environmental persistence, bioaccumulation, and long-distance migration, causing persistent organic pollution to the environment, thereby threatening environmental safety and human health.
[0003] Therefore, it is necessary to monitor perfluorinated compounds in water. Among them, water quality sampling devices are an indispensable part. Water quality sampling devices are used to collect surface water. In the early days, water pollution sources and surface water were sampled by manual sampling. This sampling method has many disadvantages. Manual sampling requires long-term investment of manpower to increase monitoring costs, and the effectiveness and efficiency of sampling are poor. Later, water quality automatic samplers appeared. The principle is to place the water inlet pipe of the peristaltic pump into the water body to be sampled, sample the water body to be sampled through the peristaltic pump, and store the collected sampled water in the sampling box.
[0004] However, the existing automatic water quality sampling device has a complex structure, low portability, and high energy consumption; and the existing automatic water quality sampling device has a low degree of automation, requiring staff to stay by the side to detect sampling and operate the device, which increases the workload of the staff.

When the sensor on the water collection bottle that is in communication with the water storage chamber detects that the water in the water collection bottle reaches a specific value, the signal is converted into an electrical signal and transmitted to the main controller. The main controller closes the control valve that was originally in an open state, and opens the next control valve that is in a closed state, and cuts off the power supply of the water pump at the same time; the support plate is slidably connected to the water collection box, so that the support plate can slide out or slide into the water collection box; the water collection bottle is detachably connected to the support plate, and the water collection bottle can be removed from the support plate, thereby transmitting the water in the water collection bottle to another detection process.

[0017] Preferably, the support plate is slidably connected to the inner wall of the water collection box via a slide rail.
[0018] Through the above arrangement, the support plate and the water collection box are connected by a slide rail, so that the support plate can slide in or out of the water collection box, and the slide rail has a simple structure and is easy to install and operate, which further simplifies the structure of the device and reduces the workload of the operator.
