Embodiment 1

[0020] See figure 1 , a sampling device for water quality detection, comprising a bracket 1, the bracket 1 is a rectangular frame structure, a sampling cylinder 2 is embedded on one side of the bottom wall of the inner cavity of the bracket 1, and the bottom end of the sampling cylinder 2 is connected to the water inlet pipe 3. A one-way valve 4 is installed on the water inlet pipe 3. A filter box 12 is provided at the bottom end of the bracket 1. The filter box 12 is sleeved on the outside of the water inlet pipe 3. The bottom end of the filter box 12 is embedded There is a water inlet cylinder 15, the water inlet cylinder 15 is a cylindrical structure with an open bottom, the bottom opening of the water inlet cylinder 15 is provided with a second filter screen 17, and the top of the water inlet cylinder 15 is uniformly provided with a number of through holes 16, so The side wall of the filter box 12 is uniformly connected with some water inlet holes 13, and the first filter ...

Embodiment 2

[0022] See Figure 1-3 The difference from Example 1 is that guide rails 5 are symmetrically arranged on the left and right sides of the inner cavity of the bracket 1, and the guide rails 5 are T-shaped guide rails, and a push plate 6 is slidably connected between the two guide rails 5. The bottom end of the push plate 6 is fixedly connected with the push rod 7 matched with the sampling cylinder 2, the push plate 6 is embedded with a screw rod 8, and the push plate 6 and the screw rod 8 are threaded, and the connection between the screw rod 8 and the guide rail 5 The relationship between them is parallel to each other. The top end of the screw rod 8 runs through the top wall of the bracket 1 and is rotatably connected to the propulsion motor 9. The bottom end of the screw rod 8 is rotatably connected to the bracket 1 through the bearing seat 11. On the bracket 1, the inner cavity of the sampling cylinder 2 is slidably connected with a piston 21, and the bottom end of the push ...

Abstract

The invention discloses a sampling device for water quality detection. The sampling device comprises a support, a sampling cylinder is embedded in one side of the bottom wall of an inner cavity of the support, the bottom end of the sampling cylinder is in through connection with a water inlet pipe, a filter box is arranged at the bottom end of the support, a water inlet cylinder is embedded in the bottom end of the filter box, and a second filter screen is arranged at an opening in the bottom end of the water inlet cylinder; a plurality of through holes are uniformly formed in the top end of the water inlet cylinder, a plurality of water inlet holes are uniformly connected to the side wall of the filter box in a penetrating manner, and first filter screens are mounted on the water inlet holes; during sampling, water enters the inner cavity of the filter box through the water inlet cylinder and the water inlet holes, and enters the sampling cylinder through the water inlet pipe, so that the sampling work is completed; and a second filter screen is arranged on the water inlet cylinder and the first filter screens are arranged in a water inlet hole, so that dead leaves, aquatic plants and other impurities in water can be effectively filtered, and the water inlet pipe can be effectively prevented from being blocked, so that the sampling work can be smoothly carried out, and the use convenience of the whole device can be greatly improved.

Description

technical field [0001] The invention relates to the field of water quality sampling devices, in particular to a sampling device for water quality testing. Background technique [0002] Sewage refers to the effluent water from domestic and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. Water after daily use contains more organic matter and is easier to handle. Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and complex components. It is not only difficult to purify in water, but also difficult to treat. The pollutants contained in industrial wastewater vary widely depending on the type of factory. Even in the same factory, the quality and quantity of pollutants contained in them are different due to different production processes. In addition to the pollution caused by ...
