[0002] A water quality analyzer is a scientific instrument used to measure and evaluate the quality of water. It can detect various parameters in water. Commonly used water quality analysis equipment includes ion chromatograph, ammonia nitrogen analyzer, UV spectrophotometer, pH meter, etc. Among them, the ammonia nitrogen analyzer uses Nessler's colorimetry to measure ammonia nitrogen in water. Ammonia nitrogen in the form of free ammonia or ammonium ions reacts with Nessler's reagent to form a yellow-brown complex, and the chromaticity of the complex is proportional to the ammonia nitrogen content.

[0003] However, there are some problems with the prior art: the existing ammonia nitrogen analyzer needs to add Nessler's reagent into the water before conducting water quality testing, and then the test personnel need to shake the water and Nessler's reagent in the test tube, which increases the workload of the test personnel. During the shaking process, the test tube is prone to touch other objects and cause damage, and manual shaking may not be able to shake the solution evenly. Therefore, we propose a water quality analysis device. Utility Model Content

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] As shown in Figures 1 to 7, an embodiment of the utility model provides a water quality analysis device, including a body 1, which is rectangular in shape and made of stainless steel. A detection device is arranged in the body 1, and the detection device includes a detection probe and a spectrometer. The detection probe is used to detect the color of the solution in the test tube, and the spectrometer is used to analyze the detected solution color, and the analysis result will be transmitted to the console 7.

[0025] An operating table 2 is fixedly connected to one side of the upper end of the body 1. The operating table 2 is a rectangular parallelepiped. A placement hole 3 is opened at one end of the operating table 2. The placement hole 3 is used to place a test tube. An upper cover 4 is rotatably connected to the placement hole 3. The function of the upper cover 4 is to prevent external factors from entering the device when the device is in use, causing damage to the device.

[0026] A hinge 8 is fixedly connected to the top of the operating table 2, and the hinge 8 is fixedly connected to one side of the upper cover 4. The upper cover 4 is rotatably connected to the operating table 2 through the hinge 8. A handle 12 is fixedly connected to the upper end of the upper cover 4. Pulling the handle 12 facilitates opening and closing the upper cover 4.

[0027] A rotating drum 5 is rotatably connected inside the body 1. A groove is provided at the upper end of the body 1, and the groove corresponds to the placement hole 3. The rotating drum 5 is rotatably connected in the groove. The test tube can enter the rotating drum 5 through the placement hole 3. The rotating drum 5 is used to drive the test tube to rotate so that the solution in the test tube is evenly mixed.

[0028] The movable end of a motor 9 is fixedly connected to the bottom end of the rotating drum 5. The motor 9 is used to drive the rotating drum 5 to rotate. The motor 9 is fixedly connected to the inner wall of the groove of the body 1. The rotation of the motor 9 will drive the rotating drum 5 to rotate, and the rotation of the rotating drum 5 can drive the test tube to rotate.

[0029] A placement groove is provided at the upper end of the rotating drum 5, and a clamping assembly 6 is arranged in the placement groove. The clamping assembly 6 is used to fix the test tube to prevent the test tube from escaping from the rotating drum 5 during rotation, causing damage to the test tube. The clamping assembly 6 includes a clamp 601. The clamp 601 is arc-shaped and made of stainless steel. The clamp 601 is arranged in two groups. The two groups of clamps 601 act together on the test tube to clamp the test tube. A rubber pad 602 is fixedly connected to the surface of the clamp 601. The shape and size of the rubber pad 602 correspond to the clamp 601. The rubber pad 602 has two functions. One is to prevent the clamp 601 from directly acting on the test tube, which may cause damage to the test tube, and the other is to increase the friction between the test tube and the clamp 601 during the rotation of the test tube to prevent the test tube from falling off.

[0030] The clamp 601 is movably connected to the inner wall of the placement groove of the rotating drum 5, and a connecting rod 603 is fixedly connected to the middle part of the clamp 601. One end of the connecting rod 603 is fixedly connected to a limit ring 604. An avoidance groove is opened on the inner wall of the placement groove of the rotating drum 5, and a spring 605 is fixedly connected to the inner wall of the avoidance groove. The spring 605 is fixedly connected to the limit ring 604. The connecting rod 603 is movably connected to the rotating drum 5 through the spring 605. When the test tube is inserted between the two groups of clamps 601, the test tube gives pressure to the clamp 601. After the clamp 601 is subjected to pressure, the connecting rod 603 contracts inwardly, and the spring 605 will be compressed. After the test tube is placed, the rebound force of the spring 605 will act on the connecting rod 603, and then act on the clamp 601. The clamp 601 will clamp the test tube, and the test tube can be fixed in the placement groove of the rotating drum 5.

[0031] A console 7 is fixedly connected to the other side of the upper end of the body 1, and a display screen 10 is fixedly connected to the upper end of the console 7. The display screen 10 is used to display the detected data. A button 11 is fixedly connected to the lower end of the console 7. The button 11 includes but is not limited to the start and stop buttons 11 of the ammonia nitrogen analyzer, the data clearing and holding buttons 11, the start and stop buttons 11 of the motor 9, etc. A processor is also provided in the console 7. The processor is used to organize the data obtained by the spectrometer to obtain the final water quality detection result. A wire hole 13 is also fixedly connected to the rear end of the console 7 for providing power to the external wiring for the ammonia nitrogen analyzer. Connection lines are provided in the body 1, the console 7 and the operating table 2 for transmitting power and signals.

[0032] The working principle of the utility model is as follows:

[0033] The tester puts the water source to be tested into the test tube, then adds Nessler's reagent into the test tube, then opens the upper cover 4 on the ammonia nitrogen analyzer operating table 2, puts the test tube into the placement hole 3, and when the test tube is placed downwardly into the clamp 601 in the rotating drum 5, the clamp 601 is squeezed and opened to both sides. After the test tube is placed, the clamp 601 is subjected to the rebound force of the spring 605 to fix the test tube in the rotating drum 5, and then presses the start button 11 of the motor 9 on the console 7. The motor 9 rotates, and then drives the rotating drum 5 to rotate, and the rotating drum 5 drives the test tube to rotate, so that the solution in the test tube is mixed evenly, and then the motor 9 is turned off, and the ammonia nitrogen analyzer is started to analyze the color of the solution in the test tube. Finally, the detected result is displayed on the display screen 10 of the console 7. After the test is completed, the ammonia nitrogen analyzer is turned off, and the test tube is pulled out, and the upper cover 4 is closed.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
