Embodiment 1

[0025] see Figure 1-3 , in an embodiment of the present invention, a sampling device for water quality detection, comprising a sampling housing 3, the inner middle part of the sampling housing 3 is provided with an inner linkage chamber 13, and the outer circumference of the inner linkage chamber 13 is provided with a plurality of An external water storage chamber 8, the middle part of the external water storage chamber 8 is provided with a movable rod 11 extending into the inner linkage chamber 13, and a water inlet and outlet is provided on the side wall of the sampling housing 3 corresponding to the middle part of the external water storage chamber 8 9. A water inlet and outlet pipe 1 is installed on the water inlet and outlet 9, a control valve 2 is arranged on the water inlet and outlet pipe 1, a plug 10 capable of blocking the water inlet and outlet 9 is installed on one end of the movable rod 11, and the other end of the movable rod 11 Rotately connected with the conne...

Embodiment 2

[0028] see Figure 1-4 , the difference between this embodiment and embodiment 1 is:

[0029] In this embodiment, the sampling housing 3 is a cylindrical structure, the inner linkage chamber 13 provided in the sampling housing 3 is a cylindrical structure, and the outer water storage chamber 8 provided outside the inner linkage chamber 13 is a fan-shaped structure, and more The volumes of the two external water storage chambers 8 are the same; the sampling housing 3 is also provided with a window (not shown) corresponding to the multiple external water storage chambers 8, which is convenient for observing the water quantity and water quality in the external storage water chambers 8. Condition.

[0030] The water inlet and outlet pipe 1 is arranged horizontally, and the water inlet and outlet pipe 1 communicates with the external water storage chamber 8 through the water inlet and outlet 9. Cooperate and communicate with the water inlet and outlet 9, and improve the effect of...

Abstract

The invention relates to the field of water quality detection, in particular to a sampling device for water quality detection, which comprises a sampling shell. An inner linkage cavity is arranged on the inner side of the sampling shell, a plurality of outer water storage cavities are arranged on the outer side of the inner linkage cavity, and a movable rod extending into the inner linkage cavity is arranged in the middle of each outer water storage cavity.The side wall of the sampling shell is provided with a water inlet and outlet corresponding to the outer water storage cavity. A plug capable of plugging the water inlet and outlet is installed at one end of the movable rod, the other end of the movable rod is rotationally connected with a connecting rod in the inner linkage cavity, and the end, away from the movable rod, of the connecting rod is hinged to a rotating shaft, and the upper end of the rotating shaft is connected with a driving motor mounted at the top of the sampling shell. The device can automatically sample water bodies at the same depth at the same time, facilitates respective detection, is flexible and convenient to use and operate, and is worthy of popularization.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to a sampling device for water quality detection. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentration and change trends of various pollutants, and evaluating the water quality status; the scope of monitoring is very wide, including unpolluted and polluted natural water (rivers, rivers, Lake, sea and groundwater) and various industrial drainage, etc.; the main monitoring items can be divided into two categories: one is a comprehensive indicator reflecting the water quality, such as temperature, color, turbidity, pH value, conductivity , Suspended matter, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand, etc.; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. [0003] When moni...
