This utility model provides a portable testing device for water conservancy projects. By incorporating a pull-out placement plate in the testing box, it not only allows for the storage and carrying of samples not yet tested at the sampling site, eliminating the need for separate sample boxes and improving portability, but also facilitates the retrieval of samples at the sampling site. The simple operation and ease of use improve the efficiency of sample testing and further enhance the practicality of the device.

[0004] However, during the use of this utility model, the water quality needs to be manually tested in multiple test tubes in sequence, resulting in low water quality testing efficiency and low automation, which cannot meet the needs of production. Therefore, a portable water quality analysis device for water conservancy projects is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a portable water quality analysis device for water conservancy projects. It has the advantage of continuously testing the water quality in multiple test tubes, solving the problem that existing water quality analysis devices require staff to manually test the water quality in multiple test tubes sequentially, resulting in low water quality testing efficiency and low automation, which cannot meet the requirements for efficient testing results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable water quality analysis device for water conservancy projects, comprising a testing box and a protective cover hinged to the top of the testing box, wherein a test tube is provided inside the testing box, and a scaled rotation mechanism capable of driving the test tube to rotate intermittently is provided inside the testing box;

[0007] The indexing and rotating mechanism includes a mounting base rotatably connected inside the testing chamber. The bottom of the test tube extends into the interior of the mounting base. A drive motor is fixedly installed inside the testing chamber. A drive disk is fixedly connected to the output shaft of the drive motor. A push rod is fixedly connected to the upper surface of the drive disk. An indexing plate is fixedly connected to the bottom of the mounting base. The indexing plate has a movable groove inside that matches the push rod.

[0008] Furthermore, the mounting base is internally fixedly connected to a rubber pad that abuts against the test tube, and the bottom of the indexing plate is rotatably connected to the testing box.

[0009] Furthermore, a snap-fit ​​block is fixedly connected to the upper surface of the drive disk, and there are two push rods, which are symmetrically distributed on the left and right sides of the snap-fit ​​block.

[0010] Furthermore, positioning blocks extending into the interior of the testing box are fixedly connected to both the left and right sides of the mounting base, and annular grooves that match the positioning blocks are formed on the inner wall of the testing box.

[0011] Furthermore, a drive box is slidably connected inside the detection box, a telescopic cylinder is fixedly installed inside the drive box, a movable rack is fixedly connected to the output end of the telescopic cylinder, a rotating rod extending to the top of the detection box is rotatably connected inside the drive box, and a gear that meshes with the movable rack is fixedly installed outside the rotating rod.

[0012] Furthermore, a connecting plate is fixedly connected to the top of the rotating rod, and a detection head is fixedly connected to the side of the connecting plate near the test tube.

[0013] Furthermore, a dual-axis cylinder is fixedly installed on the inner bottom wall of the detection box, and the output end of the dual-axis cylinder is fixedly connected to the bottom of the drive box.

[0015] Compared with the prior art, this utility model provides a portable water quality analysis device for water conservancy projects, which has the following beneficial effects:

[0016] 1. The portable water quality analysis device used in this water conservancy project has a mounting base for easy positioning and installation of multiple test tubes. A drive motor drives a drive disc to rotate, which in turn drives a push rod to rotate. A movable groove allows the push rod to rotate a scale plate, thus achieving intermittent rotation of the test tubes. This facilitates continuous testing of the water quality in multiple test tubes and improves testing efficiency.

[0017] 2. The portable water quality analysis device used in this water conservancy project uses a telescopic cylinder to move a moving rack, which in turn drives a gear to rotate, thereby rotating the connecting plate and the detection head. A dual-axis cylinder allows the detection head to enter and exit the test tube, facilitating water quality testing. This solves the problem of existing water quality analysis devices requiring manual testing of multiple test tubes sequentially, resulting in low efficiency and low automation, failing to provide high-efficiency testing results.
