By setting the inspection plate, a waterproof protection function is played, which can prevent the components inside the protective frame 15 from being exposed to water for a long time and affecting normal operation.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The dredging and cleaning mechanism 4 includes an auxiliary bent plate 20, the bottom of which is fixedly connected to the right cover plate 3, the front and rear sides of the top of the auxiliary bent plate 20 are both penetrated by a guide rod 21 for sliding connection, the bottom end of the guide rod 21 penetrates the right cover plate 3 and is fixedly connected to an angle plate 22, the left side of the angle plate 22 is fixedly connected to a mounting frame plate 23, the front and rear sides of the left side of the mounting frame plate 23 are both slidably connected to the mounting groove 10 through a travel groove, the left side of the mounting frame plate 23 is fixedly connected to a cleaning plate 24, the front and rear sides of the bottom of the angle plate 22 are fixedly connected to reinforcing ribs, and the top of the guide rod 21 is fixedly connected to a grip rod, by setting the grip rod, it plays a role of assisting downward pressure, making it convenient for the user to press down the guide rod 21 more easily.

The bottom wall contacts or inserts into the ground, and this mechanism can effectively enhance the stability of the device, so that during the use of the device, the device can avoid shaking in the liquid due to the instability of the liquid, prevent collision damage, thereby completing the stable reinforcement treatment. After use, it is generally necessary to dredge the blocking mesh 11. First, after stopping the machine, manually press down the guide rod 21 through the grip rod.
