Description

Technical Field

[0001] The utility model relates to the technical field of wastewater detection samplers, in particular to a wastewater detection sampler. Background Art

[0002] When the environmental monitoring department conducts wastewater testing, on-site water sampling is the first step in quality control. The sampling is required to be disturbed as little as possible to ensure the accuracy of the test results. When sampling sewage or treated water to be discharged, the testing agency often uses a portable sampler. The existing portable sampler is generally placed directly on the ground during use, which is convenient for moving and changing its position. It is not convenient to test water sources in different areas, resulting in its poor adaptability. In addition, in the existing technology, the sampling water tank is mostly fixed with bolts, which is not convenient for quick installation and disassembly of the sampling water tank, and it is not convenient to clean the inside of the sampling water tank or replace the sampling water tank. It may cause cross-contamination between the newly taken wastewater sample and the original wastewater sample, thereby reducing the accuracy and reliability of each sampling; therefore, we propose a wastewater detection sampler to solve this problem.

At this time, the sampling water tank can be effectively cleaned and replaced. This structure is simple and easy to operate, and is convenient for the installation, disassembly, cleaning and replacement of the sampling water tank. Timely cleaning of the water tank can remove residual pollutants and avoid cross-contamination of newly collected wastewater samples, thereby ensuring the accuracy and reliability of each sampling, avoiding erosion and damage to the water tank by dirt and corrosive substances, extending the service life of the sampling water tank, and reducing equipment replacement costs.

[0021] Preferably, a moving assembly 5 is provided inside the fixing frame 1, and the moving assembly 5 includes: a bidirectional screw rod 501, the outer side of the bidirectional screw rod 501 is threadedly connected to two sets of threaded plates 502, both sides of the two sets of threaded plates 502 are hinged with connecting rods 503, the bottom ends of the four sets of connecting rods 503 are hinged to the same set of fixed shafts, both ends of the fixed shafts are fixedly installed with fixed blocks 504, the bottoms of the two sets of fixed blocks 504 are fixedly installed with connecting plates 11, and the bottoms of the connecting plates 11 are fixedly installed with four sets of universal wheels 12 , which is convenient for the lifting and lowering of the universal wheel 12, and is convenient for the movement of the device to detect different areas and the stability of the device during sampling and detection. A water pump 2 9 is fixedly installed at the bottom end of the water inlet pipe, and two sets of brackets are fixedly installed on the outside of the water pump 2 9. The two sets of brackets are fixedly connected to the box body 2. The bottom end of the water pump 2 9 is fixedly connected to the hose 2 10.

A hose 1 7 is fixedly installed on the top of the water pump 1 6, which is convenient for sampling and detection of wastewater.

[0022] Preferably, the bidirectional screw rod 501 is rotatably mounted on the inner walls of both sides of the fixing frame 1, and a motor 14 is fixedly mounted on one side of the fixing frame 1.
