The bottom outer wall of the rotating frame 201 is rotatably connected with an auxiliary wheel 205 through a rotating shaft. The auxiliary wheel 205 is used to improve the stability of the rotating frame 201 during rotation. The auxiliary wheel 205 is rollingly connected to the inner wall of the second groove 105. The top outer wall of the rotating frame 201 is fixedly connected with a first motor 203, and the output end of the first motor 203 is fixedly connected with a driving wheel 204. The outer surface of the driving wheel 204 is rotatably connected to the inner wall of the first groove 104. The inner wall of the rotating frame 201 is fixedly connected with a first connecting frame 206, and the outer wall of the first connecting frame 206 at one end away from the rotating frame 201 is fixedly connected with a second motor 207. The number of the second motors 207 is four, and the four second motors 207 are symmetrically arranged with the rotating frame 201 as the center, and the output end of the second motor 207 runs through the first connecting frame 206. The first motor 203 is fixedly connected with a rotating shaft 208, and a detection component 209 is arranged at the output end of the second motor 207. The detection component 209 includes a first sliding block 2093 which is slidably connected with the rotating shaft 208.

[0024] The top of the sampling cup 107 is fixedly connected to the fixed block 106. The sampling cup 107 is made of completely transparent glass. The bottom outer wall of the sampling cup 107 is fixedly connected to the detection box 101. The bottom outer wall of the sampling cup 107 is fixedly connected with a sewage pipe 111. The top of the sampling cup 107 passes through the fixed block 106 and is fixedly connected with a water inlet pipe 109. The end of the fixed block 106 away from the water inlet pipe 109 and away from the fixed block 106 is fixedly connected with a sampling tube 110. When it is necessary to detect the environmental water sample, the sampling tube 110 can be used to detect the environmental water sample. 110 injects the environmental water sample into the sampling cup 107. After the optical detector 20910 completes the detection of the environmental water sample, the environmental water sample in the sampling cup 107 is discharged with the help of the drain pipe 111. Subsequently, clean purified water is injected into the sampling cup 107 with the water inlet pipe 109 to clean the inner wall of the sampling cup 107. Such operation can prevent the residual environmental water sample residue from having a negative impact on the subsequent detection operation, thereby ensuring the accuracy and reliability of the detection work and providing stable and accurate data support for the entire detection process.

[0025] The top outer wall of the fixed block 106 is fixedly connected with a support rod 108, which supports the sampling tube 110 and the water inlet pipe 109.

Under this action, the support block 2099 slides along the outer wall of the arc rod 2094 with the help of the second sliding block 20913, so that the support block 2099 drives the optical detector 20910 to deflect the angle. In this way, the optical detector 20910 can analyze the substances in the water sample from different angles, thereby improving the credibility of the detection results.

[0027] The second fixed frame 2091 is set to be semicircular, and the second fixed frame 2091 is deflected around the sampling cup 107 through the driving roller 2097. The auxiliary light source 2092 is used to supplement the light source during environmental water sample detection. The auxiliary light source 2092 provides auxiliary lighting for the environmental water sample to facilitate the optical detector 20910 to detect the environmental water sample. The second fixed frame 2091 causes the support blocks 2099 on both sides thereof to slide relative to each other, thereby ensuring that the optical detector 20910 is always in a aligned state.

[0028] The outer wall of the second fixed frame 2091 is rotatably connected to the second connecting frame 2098 through a rotating shaft, a support block 2099 is arranged outside the second connecting frame, an outer wall of the support block 2099 away from the second connecting frame 2098 is fixedly connected to the optical detector 20910, the outer wall of the support block 2099 is fixedly connected to the second sliding block 20913, the outer surface of the second sliding block 20913 is slidably connected to the arc rod 2094, the inner wall of the second sliding block 20913 is rotatably connected to the second connecting frame 2098, and the third motor 2096 is connected to the second connecting frame 2098 through the third motor 2096. The driving roller 2097 slides in the through hole 2095 of the arc rod 2094, thereby driving the second connecting frame 2098 to slide. Under this driving action, the support block 2099 slides along the outer wall of the arc rod 2094 through the second sliding block 20913, thereby driving the optical detector 20910 to deflect the angle. In this way, the optical detector 20910 can analyze the substances in the water sample from different angles, thereby effectively improving the credibility of the detection results and providing more comprehensive and accurate data support for water sample detection.

[0029] A connecting shaft 20911 is fixedly connected to the outer wall of one side of the support block 2099 close to the second connecting frame 2098. The function of the connecting shaft 20911 is to improve the stability of the support block 2099 during movement. The end of the connecting shaft 20911 away from the support block 2099 passes through the second connecting frame 2098 and is fixedly connected to a spring 20912. The end of the spring 20912 close to the support block 2099 is fixedly connected to the second connecting frame 2098. The second connecting frame 2098 can ensure that the second sliding block 20913 is always tightly fitted with the arc rod 2094 during the sliding process. Under its action, the support block 2099 relies on the second sliding block 20913 to slide along the outer wall of the arc rod 2094, thereby driving the optical detector 20910 to produce an angular deflection.
