The surface of the cleaning tank 421 is provided with a channel for communicating the sampling chamber 62, the channel is provided with a sealing plate 425, the sealing plate 425 is rotatably connected with a fixing rod fixed on the surface of the cleaning tank 421 through a torsion spring, when the detection end of the detector 422 moves, the sealing plate 425 can be pushed open, the detector 422 enters the sampling chamber 62 to detect water quality, and when the detector 422 finishes detection and retracts to the detection box 42, the sealing plate 425 can seal the cleaning tank 421 under the elastic action of the torsion spring again, so that external river water is prevented from entering the cleaning tank 421.
Furthermore, as shown in fig. 4, in order to facilitate the detection of river water at different positions and at the same depth by using one detection mechanism 4, a first electromagnetic slide rail 426 is fixed inside the detection box 42, a moving assembly is slidably connected to the first electromagnetic slide rail 426, the moving assembly includes a mounting box and a second electric push rod 423 mounted in the mounting box, a push rod is fixed at an output end of the second electric push rod 423, a rotating shaft 427 is fixed at the other end of the push rod, a supporting plate 428 is fixed on a surface of the rotating shaft 427, an outer periphery of the supporting plate 428 is rotatably connected to the mounting box, a fixed block 424 is fixed on a surface of the supporting plate 428, a second electromagnetic slide rail is fixed on an upper surface of the fixed block 424, the detector 422 is slidably connected to the second electromagnetic slide rail, the second electromagnetic slide rail is arranged at a right angle to the first electromagnetic slide rail 426, the mounting box is moved back and forth by controlling an output end 428 of the second electric push rod 423 to extend out, the push rod drives the supporting plate to rotate, the supporting plate 424 rotates to another side surface of the fixed block 42, and extends out of the detector 422 to achieve effective detection of river water at different positions without using different detection equipment, and reducing the detection cost.
Further, as shown in fig. 4 and 8, in consideration of the fact that the cleaned water needs to be discharged after the detection end of the detector 422 is cleaned, a water outlet is formed in the bottom of the cleaning tank 421, the water outlet is communicated with a water discharge tank 43 through a pipeline, the water discharge tank 43 is fixed in the detection mechanism 4, a water discharge port communicated with the outside is formed in the bottom of the water discharge tank 43, the water discharge port is bent, and a filter screen 431 is fixed on the water discharge port to prevent solid impurities such as stones in the river from entering the water discharge tank 43.
