[0057] In the third embodiment, on the basis of the above-mentioned embodiments:

[0058] Please refer to Figures 5 to 8The cleaning component in the embodiment one is disclosed as follows, the cleaning component comprises: a main shaft 13, the end of the main shaft 13 is rotatably connected with the inner wall of the bottle cap 1, the shaft arm of the main shaft 13 is slidably connected with an adjusting sleeve 14 in a spline manner, the outer wall of the adjusting sleeve 14 is fixedly connected with an incomplete gear one 15, the inner wall of the bottle cap 1 is rotatably connected with a rotating shaft 16, the shaft arm of the rotating shaft 16 is fixedly connected with a gear 17, the gear teeth of the gear 17 are intermittently engaged with the gear teeth of the incomplete gear one 15, the shaft arm of the rotating shaft 16 is sleeved with a displacement block 18, the surface of the displacement block 18 is vertically slidably connected with the inner wall of the bottle cap 1, the top surface of the displacement block 18 is rotatably connected with the bottom surface of a rotating plate 19, the shaft arm of the rotating shaft 16 is slidably connected with the rotating plate 19 in a spline manner, the two ends of the rotating plate 19 are fixedly connected with cleaning rods 20, respectively, and the ends of the two cleaning rods 20 are fixedly connected with the surfaces of two cleaning blocks 4.

Since the gear teeth of the gear 17 are trapezoidal, during the continuous rotation of the incomplete gear one 15, the first gear tooth in contact with the circular arc edge of the incomplete gear one 15 will be pushed first, causing the gear tooth one to deflect slightly around the rotating shaft 16. The slight deflection of the gear tooth one with the gear 17 will cause the adjacent gear tooth two to come into contact with the circular arc edge of the incomplete gear one 15. The continuous rotation of the incomplete gear one 15 will cause the adjacent gear tooth two to deflect slightly in the opposite direction around the rotating shaft 16. This process will continue until the gear tooth one comes into contact with the circular arc edge of the incomplete gear one 15 again. Thus, the gear 17 can be shaken around the rotating shaft 16 by the continuous rotation of the incomplete gear one 15 during this process. Through the shaking of the gear 17 during this process, the two cleaning blocks 4 can be shaken through the transmission of the rotating shaft 16, the rotating plate 19, and the two cleaning rods 20.

[0063] More specifically, in the present embodiment: when the detected regional environment is relatively dirty, the electric push rod 21 can be first started, so that the adjusting rod 22 is displaced in the vertical direction, and the adjusting sleeve 14 is displaced upward in the vertical direction, so that the teeth of the incomplete gear one 15 are disengaged from the teeth of the gear 17, and the teeth of the incomplete gear two 24 are engaged with the teeth of the gear 17, at this time, rotating the adjusting sleeve 14 can make the gear 17 rotate through the incomplete gear two 24, and since the number of teeth of the incomplete gear two 24 is twice the number of teeth of the incomplete gear one 15, the intermittent frequency of movement of the two cleaning blocks 4 can be changed, that is, the two cleaning blocks 4 can clean the filter screen 3 at a higher frequency to keep it unobstructed.

[0070] More specifically, in this embodiment: in the process of rotating the rotating shaft 16, the lifting plate 29 is driven to rotate, through the rotation of the lifting plate 29, the oval groove 30 is rotated, since the displacement block 18 is limited by the bottle cap 1 and cannot rotate, that is, the two connecting shafts 31 cannot move in a circular direction, so that the two connecting shafts 31 move in opposite directions with the rotation of the oval groove 30, so that the displacement block 18 moves up and down through the transmission of the two hinged rod groups 32, that is, the rotating plate 19 is pushed to change the vertical height of the rotating plate 19 through the up and down movement of the displacement block 18, so that the vertical height of the two cleaning blocks 4 changes, so that the two cleaning blocks 4 move in a circular direction with a wave feature, which facilitates pushing away the impurities on the filter screen 3 when cleaning the impurities, so that the cleaning effect is better and the water sampling efficiency is further improved.

[0071] Embodiment seven, on the basis of the above embodiment:

[0075] Please refer to Figure 1 The surface of the bottle body 2 is provided with a plurality of reflective strips 34, and the reflective strips 34 are arranged in a ring shape at equal intervals.

[0076] More specifically, in this embodiment, the reflective strips 34 can facilitate the use of the staff, and can facilitate the preliminary observation of the personnel on the shore in the water.

[0077] Working principle: when the underwater sampling device is used, the device can be installed on the underwater robot, and can be operated by the manipulator provided on the underwater robot during underwater work. The underwater robot carries a plurality of the device into the water, and when it reaches the measurement area, the bottle cap 1 is separated from the bottle body 2 by starting the electric push rod 7. At this time, the external water flow can flow into the bottle body 2. When the water flow enters the bottle body 2, it is filtered by the filter screen 3 to prevent debris such as waterweeds from flowing into the bottle body 2 and affecting water sampling.

[0078] At the same time, the motor 33 can be started to make the two cleaning blocks 4 move intermittently with a circular trajectory feature, so that the filter screen 3 is not blocked. When the cleaning blocks 4 stop moving, they vibrate, which can cooperate with the flowing water flow to achieve the self-cleaning effect of the cleaning blocks 4.

[0079] At the same time, the operator can preliminarily judge the water area according to the water area, and when the water area is poor, the electric push rod 21 can be started to increase the cleaning frequency of the cleaning blocks 4, so as to better clean the filter screen 3 and ensure the efficiency of water sampling. At the same time, the filter screen 3 can vibrate to further improve the smoothness of the filter screen 3 and avoid blockage affecting the water sampling work.

[0080] During the circular displacement of the cleaning blocks 4, the vertical height will also change, so that the two cleaning blocks 4 change from circular trajectory displacement to circular displacement with a thin cooling feature. When cleaning the impurities on the filter screen 3, the impurities can be easily pushed away, so that the cleaning effect is better and the water sampling efficiency is further ensured.

[0081] While embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
