However, when it is necessary to collect water samples at different depths, it is necessary to manually place the sampler at different depths multiple times to collect water, which is quite troublesome. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution:

[0020] A fully automatic sample collection and testing device includes a base plate 1, on which a detection mechanism 2 and a sampling mechanism 3 are disposed. The detection mechanism 2 includes a sample placement component 21 for holding samples disposed on the base plate 1. A detection component 22 for detecting the water quality of the sample is disposed on one side of the sample placement component 21. A cleaning component 23 for cleaning the detection component 22 is disposed below the detection component 22. The sampling mechanism 3 is capable of collecting and transporting samples into the sample placement component 21.

[0021] In this embodiment, the sample placement assembly 21 includes a switching motor 2101, which is fixedly connected to the base plate 1. A rotating disk 2102 is fixedly connected to the output shaft of the switching motor 2101. Six mounting slots 2103 are evenly opened on the rotating disk 2102, and sample placement boxes 2104 are slidably inserted into three of the mounting slots 2103 that are at a 220° angle.

[0022] In this embodiment, the detection component 22 includes a mounting bracket 2201, which is fixedly connected to the base plate 1. Two guide rods 2202 are fixedly connected in parallel on the mounting bracket 2201. A movable connecting block 2203 is slidably connected to the guide rods 2202. A lead screw 2204 is also rotatably connected to the mounting bracket 2201. The movable connecting block 2203 is threadedly connected to the lead screw 2204. A lifting motor 2205 is also fixedly connected to the mounting bracket 2201. The lead screw 2204 is fixedly connected to the output shaft of the lifting motor 2205. A detection probe 2206 of a water quality analyzer is fixedly connected to the movable connecting block 2203.

[0023] In this embodiment, the cleaning component 23 includes a support bracket 2301, which is fixedly connected to the base plate 1. A hollow ring block 2302 is fixedly connected to the support bracket 2301. The hollow ring block 2302 is located directly below the detection probe 2206. A plurality of water outlet holes 2303 are evenly opened on the inner wall of the hollow ring block 2302. A water inlet pipe 2304 for introducing pure water is fixedly connected to the hollow ring block 2302. An electrically controlled valve 2305 is fixedly connected to the water inlet pipe 2304.

[0024] In this embodiment, a baffle plate is provided on the base plate 1 between the support bracket 2301 and the switching motor 2101 to prevent the water flow from cleaning the detection probe 2206 from flowing to the switching motor 2101 and causing water ingress and damage to the switching motor 2101.

[0025] In this embodiment, the sampling mechanism 3 includes a float 301, which is placed in the water area to be tested. An installation plate 302 is fixedly connected to the float 301. Several water pumps 303 are evenly fixedly connected from top to bottom on the installation plate 302. Each water pump 303 is fixedly connected to a water delivery pipe 304 for conveying water drawn by the water pump 303. A connecting bracket 305 is fixedly connected to the base plate 1. The outlet end of each water delivery pipe 304 is fixedly connected to the connecting bracket 305.

[0026] In this embodiment, the length of the water supply pipe 304 is long enough so that when the float 301 and the mounting plate 302 float in the water area to be tested, the connecting bracket 305 can be placed on the shore of the water area to be tested along with the base plate 1, making it convenient for the user to record the test results.

[0027] The fully automated sample collection and testing device operates as follows:

[0028] Start the lifting motor 2205, which drives the lead screw 2204, which is fixedly connected to its output shaft, to rotate. Since the movable connecting block 2203 is threadedly connected to the lead screw 2204 and slidably connected to the guide rod 2202, the movable connecting block 2203 slides along the guide rod 2202 under the drive of the lead screw 2204. At this time, the rotation direction of the lifting motor 2205 causes the movable connecting block 2203 to move downward, and the detection probe 2206, which is fixedly connected to the movable connecting block 2203, also moves downward. After the detection probe 2206 moves down a certain distance, it will probe into the water sample in the sample placement box 2104 below. At this time, turn off the lifting motor 2205 to stop the detection probe 2206 from moving and perform water quality testing on the sample.

[0029] During the detection process of probe 2206, a water pump 303 is started. The water pump 303 will draw water samples from a specific depth of the water area to be tested and deliver them through water pipe 304 to the empty sample placement box 2104 directly opposite the opening of water pipe 304. After the water sample in the sample meets the detection requirements, the water pump 303 is turned off.

[0030] After the test is completed, the lifting motor 2205 is started and shut off after the detection probe 2206 moves up and resets. The switching motor 2101 is started, and the rotating disk 2102, which is fixedly connected to its output shaft, rotates 60° and then shuts off. At this time, the sample placement box 2104 moves away from below the detection probe 2206. The mounting slot 2103 is below the detection probe 2206. The lifting motor 2205 is started again, so that the detection probe 2206 moves down and extends into the hollow ring block 2302 after passing through the mounting slot 2103. At this time, the electric control valve 2305 is opened, and pure water flows into the hollow ring block 2302 from the water inlet pipe 2304 and finally sprays out from the water outlet 2303 to rinse the detection probe 2206 at the center of the hollow ring block 2302. After rinsing, the detection probe 2206 moves up and resets and the electric control valve 2305 is closed.

[0031] Then, the switching motor 2101 is restarted to rotate the rotating disk 2102 by 60°, and another sample placement box 2104 containing water sample is moved under the detection probe 2206. The detection probe 2206 is moved again for detection. During this process, another water pump 303 is started to transport water sample from another depth to the empty sample placement box 2104. At the same time, the previously tested sample placement box 2104 is removed from the mounting slot 2103 and a new empty sample placement box 2104 is placed.
