Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, and in particular relates to a portable water quality tester for water quality testing. Background Technology

[0002] Water quality testing is essential for protecting human health and preventing harm from heavy metals, microorganisms, and chemical pollutants in water. It also meets the production needs of industry and agriculture, preventing poor water quality from affecting product quality and damaging equipment. Furthermore, it monitors the ecological condition of natural water bodies, promptly detects pollution problems, and provides a scientific basis for water quality management, environmental protection, and the rational use of water resources.

[0003] Existing water quality analyzers have several drawbacks. For example, directly pumping water into the device allows impurities to enter and adhere to the analyzer, affecting test results. Additionally, sedimentation can occur in water samples during use, leading to inaccurate results. Therefore, we propose a portable water quality analyzer for testing. Utility Model Content

[0004] The purpose of this invention is to provide a portable water quality analyzer for water quality testing, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a portable water quality analyzer for water quality testing, including a housing, a cylinder, and a detection electrode, and further comprising:

[0006] A fixed housing is fixedly installed on one side of the housing. A fixed frame is inserted into the fixed housing, and a filter screen is fixedly installed in the fixed frame. The cylinder is fixedly installed on the top of the housing, and the detection electrode is fixedly installed on the telescopic end of the cylinder.

[0007] A first rotating column is rotatably installed inside the housing, and a plurality of first stirring blades are fixedly installed on the first rotating column. Two second rotating columns are rotatably installed inside the housing and below the first rotating column, and a plurality of second stirring blades are fixedly installed on each of the two second rotating columns.

[0008] A fixing component, located within a fixing shell, is used to fix the position of the fixing frame;

[0009] A drive assembly, located on the housing, is used to drive the first rotating column and two second rotating columns to rotate.

[0010] In this technical solution, when the whole device is in use, water first enters the fixed shell, and then the water is filtered by the filter screen. Large particles of impurities in the water remain on the top of the filter screen, while water without large particles of impurities enters the shell. Through the set drive component, the first rotating column can be driven to rotate, and the first rotating column drives several first stirring blades to rotate. Through the set drive component, the two second rotating columns can be driven to rotate, and the two second rotating columns drive several second stirring blades to rotate. The several second stirring blades and several first stirring blades can evenly stir the water in the shell, ensuring that the water sample does not precipitate.

[0011] When it is necessary to disassemble the fixing frame, the staff can remove the fixing frame using the set fixing components, clean the impurities on the top of the filter screen, and then insert the fixing frame into the fixing shell. The fixing components can fix the position of the fixing frame, which facilitates the installation and disassembly of the fixing frame and the cleaning of the filter screen.

[0012] In the above technical solution, the fixing component further includes:

[0013] A limiting groove is provided, which is located inside the fixed shell and at the bottom of the fixed frame. A rectangular plate is slidably installed in the limiting groove. Several fixed posts are fixedly installed at the bottom of the rectangular plate. A spring is sleeved on each of the fixed posts. Two guide grooves are provided inside the rectangular plate. Guide posts are slidably installed in both guide grooves. Limiting posts are fixedly installed on both guide posts. The upper ends of both limiting posts extend into the fixed frame, and both limiting posts are inserted into the fixed frame.

[0014] In this technical solution, when the fixed frame needs to be disassembled, firstly, the rectangular plate is pulled downwards, causing several fixed posts to slide downwards. Simultaneously, several springs are compressed and contracted. The rectangular plate, through two guide grooves, causes two guide posts to move downwards, and the two guide posts, in turn, cause two limiting posts to rotate downwards. Once both limiting posts have disengaged from the fixed frame, the worker can remove the fixed frame, clean the impurities on the top of the filter screen, and then insert the fixed frame into the fixed housing. Releasing the rectangular plate, under the rebound force of the springs, causes the rectangular plate and several fixed posts to slide upwards. The rectangular plate, through two guide grooves, causes two guide posts to move upwards, and the two guide posts, in turn, cause two limiting posts to rotate upwards. Both limiting posts are then inserted into the fixed frame, fixing its position and facilitating installation, disassembly, and cleaning of the filter screen.

[0015] In the above technical solution, the driving component further includes:

[0016] The power chamber is located within the housing. A motor is fixedly mounted on the housing. The output shaft of the motor passes through the housing and extends into the power chamber.

The bottom end of one worm wheel passes through the power chamber and is fixedly connected to a first rotating column. A first bevel gear is fixedly mounted on the bottom end of the other worm wheel. A second bevel gear is meshed on the bottom of the first bevel gear. A first gear is fixedly mounted on one end of the second bevel gear. Second gears are meshed on both sides of the first gear. One end of each of the two second gears passes through the power chamber and is fixedly connected to two second rotating columns, respectively.

[0017] In this technical solution, when the entire device is in use, water first enters the fixed shell, and then the water is filtered by the filter screen. Large particles of impurities in the water remain at the top of the filter screen, while water without large particles of impurities enters the shell. At the same time, the motor is started, and the motor drives the worm gear to rotate. The worm gear drives the two worm wheels meshing with it to rotate. The two worm wheels drive the first rotating column and the first bevel gear to rotate respectively. The first rotating column drives several first stirring blades to rotate. The first bevel gear drives the second bevel gear meshing with it to rotate. The second bevel gear drives the first gear to rotate. The first gear drives the two second gears meshing with it to rotate. The two second gears drive the two second rotating columns to rotate respectively. The two second rotating columns drive several second stirring blades to rotate. The several second stirring blades and the several first stirring blades can uniformly stir the water in the shell, ensuring that the water sample does not precipitate.

[0018] In the above technical solution, both of the limiting posts are rotatably connected to the limiting groove, and the plurality of fixed posts are slidably connected to the limiting groove. The output shaft of the motor is rotatably connected to the housing and the power cavity. The worm, the two worm wheels, the first bevel gear, the second bevel gear, the first gear, and the two second gears are all rotatably connected to the power cavity.

[0021] In this technical solution, it is ensured that several second stirring blades and several first stirring blades can uniformly stir the water in the shell, ensuring that the water sample will not precipitate.

[0022] In the above technical solution, the diameter of the guide post is adapted to the size of the guide groove.

[0023] In this technical solution, it is ensured that the guide post can slide stably within the guide groove.

[0024] In the above technical solution, the bottom of the filter screen and the bottom of the fixed frame are located on the same horizontal plane, and the thickness of the filter screen is less than the thickness of the fixed frame.

[0025] In this technical solution, large particulate impurities in the water are ensured to remain at the top of the filter screen.
