Description

Technical Field

[0001] This utility model relates to the field of heavy metal detection technology, specifically a portable rapid metal ion detection device. Background Technology

[0002] In recent years, people's awareness of environmental protection has grown rapidly. With the rapid development of modern society and economy, the application of heavy metals in industrial and agricultural production has become more and more widespread, leading to increasingly serious heavy metal pollution in the environment. At the technical level, the main development direction for heavy metal detection in soil is to use rapid detection technology to conduct preliminary on-site monitoring and screening of heavy metals, and then combine it with traditional detection methods for accurate laboratory measurement. Therefore, it is necessary to use portable rapid metal ion detection devices to conduct rapid detection.

[0003] Chinese Utility Model Patent Publication No. CN 215678098 U discloses a portable heavy metal detection device. This device contains a detection chamber containing a solution to be tested. Ultraviolet light is irradiated onto the detection chamber via an ultraviolet generator, and fluorescence is measured using a fluorescence detection device to determine the concentration of heavy metal ions. The detection chamber, ultraviolet generator, and fluorescence detection device are all located within a housing, allowing the device to be taken to the field for analysis by simply carrying the housing, thus improving portability. However, the inclusion of both the ultraviolet generator and fluorescence detection device results in a high power requirement, making it inconvenient for outdoor use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a portable rapid metal ion detection device, which can effectively solve the problems of existing devices having ultraviolet generators and fluorescence detection devices, resulting in a large power demand and inconvenience for field use.

[0005] The technical solution adopted by this utility model is as follows: a portable rapid metal ion detection device, including a base, a first support leg and a second support leg at the lower end of the base, a locking assembly fixedly connected to the lower end of the base, a flip plate at the upper end of the base, a reinforcing brace fixedly connected to the outer side of the flip plate, a slot fixedly connected to the outer side of the flip plate, a base box fixedly connected to the upper end of the base, a latch fixedly connected to the front end of the base box, a cover door rotatably connected to the upper end of the cover door, a telescopic handle fixedly connected to the upper end of the cover door, a second locking assembly fixedly connected to the upper end of the cover door, a lock head fixedly connected to the front end of the cover door, a pulley fixedly connected to the rear end of the base, and multiple detection components arranged inside the base box;

[0006] The locking assembly includes a telescopic rod, a spring, and a pressure plate. The telescopic rod is provided with a spring on its outer side, and the lower end of the telescopic rod is rotatably connected to the pressure plate.

Multiple test strip boxes are mounted on the upper end of the detection platform. Multiple liquid storage tubes are mounted on the upper end of the detection platform. A tube wall brush is installed inside each liquid storage tube. An extrusion cap is located on the right side of each liquid storage tube, and a pre-reserved slot is formed on the outer side of the extrusion cap. Multiple swab rods are mounted on the upper end of the detection platform. A stirring brush is fixedly connected to the outer side of each swab rod, and a swab stick is attached to the end of each swab rod.

[0010] The above technical solution includes two support legs. When the detection device is in use, support legs one and two are rotated downwards and opened until the flat groove of support leg one contacts the lower end of the base, and the flat groove of support leg two contacts the lower end of the base. The angle between support legs one and two and the base is 120°-125°, which provides good support and facilitates rapid detection of cadmium ions after deployment.

[0012] The above technical solution includes a locking component. When support leg 1 and support leg 2 come into contact with the base, pulling pressure plate 1 stretches the telescopic rod, spring 1 extends, and pressure plate 1 is rotated until the long slots of pressure plate 1 and support leg 2 correspond. When pressure plate 1 is released, spring 1 contracts and presses pressure plate 1 into the long slots of support leg 2, thus limiting the movement of support leg 1 and support leg 2. This makes operation convenient.

The flap increases the operating space of the rapid detection device, facilitating its use in the field. A second locking component is also included. When the flap is rotated to close, it contacts the cover door. Pulling the second pressure plate stretches the second spring. Rotating the second pressure plate until it aligns with the slot allows the spring to retract, and the pressure plate is then inserted into the slot, securing the flap. The fixing method is simple.

[0020] Using the above technical solution, during testing, the user takes the swab and makes full contact with the soil or liquid to be tested. The extrusion cap is rotated to separate it from the storage tube. The swab is inserted into the storage tube, and the swab is rotated. The tube wall brush removes the soil or liquid from the swab surface, and the stirring brush thoroughly mixes the soil or liquid with the extract inside the storage tube. The extrusion cap is threaded onto the storage tube, and the end of the extrusion cap is broken off along the pre-reserved groove to expose its hollow structure. The storage tube is squeezed to expel 3-4 drops of the mixed liquid, which are then dripped onto the test strip in the test kit. The test results can be observed after 15-20 minutes. The testing process is short and fast.
