The cavity 202g provides a storage space for the launching condition 202e. The spring rod 202c bounces the embedded block 202d to the side of the launching condition 202e. One end of the restoring spring 202f is connected to the horizontal plate 202b, and the other end is connected to the inner wall of the water collecting box 201a, which is used to restore the first touch-pressure rod 202a.

[0039] Furthermore, the transmission condition 202e includes a gear 202e-1 arranged on the water collecting tank 201a, a power storage bar 202e-2 is installed on the top side of the gear 202e-1, a pillar 202e-3 is installed on the top of the gear 202e-1, the outer wall of the pillar 202e-3 is connected to one end of the power storage bar 202e-2, and the other end of the power storage bar 202e-2 is connected to the inner wall of the water collecting tank 201a, and the pillar 202e-3 can rotate to store power on the gear 202e-1.

[0040] Furthermore, the vibration component 203 includes a slider member 203a arranged on the water collecting tank 201a, a cylinder 203b is installed on the top of the slider member 203a, a rocking arm 203c is movably connected to one side of the cylinder 203b, a rotating wheel 203d is installed on the top of the pillar 202e-3, the rotating wheel 203d is movably connected to the rocking arm 203c through a pin shaft, a fixed plate is installed at the bottom of the filter plate 201c, and multiple groups of semi-circular balls are installed on the bottom side of the fixed plate, and the gaps between the semi-circular balls are in contact with the top of the cylinder 203b.

[0042] The rest of the structure is the same as that of Example 1.

[0043] Operation process: When cleaning, the staff puts the water collecting box 201a on the inner wall of the coal bunker. At this time, the first contact pressure rod 202a drives the horizontal plate 202b to move due to the contact pressure. The movement of the horizontal plate 202b drives the embedded block 202d on the spring rod 202c to move. The embedded block 202d is embedded in the tooth tip of the gear 202e-1. When the first contact pressure rod 202a is pressed, the right-angled surface of the embedded block 202d contacts the tooth tip of the gear 202e-1, so that the embedded block 202d drives the gear 202e-1. The gear 202e-1 rotates to drive the support 202e-3 to rotate, and the support 202e-3 rotates to slightly store the force storage bar 202e-2 on the support 202e-3. When the first touch-pressure rod 202a is not touched, that is, when the cleaning point is changed, the restoring spring 202f restores the horizontal plate 202b and the first touch-pressure rod 202a. At this time, the inclined surface of the embedded block 202d contacts the tooth tip of the gear 202e-1, so that the embedded block 202d is retracted into the horizontal plate 202b, thereby not affecting the first The touch-pressure rod 202a is restored. With each replacement of the cleaning point, the force storage bar 202e-2 is also charged each time. When the attachments block the filter holes of the filter plate 201c, the touch rod 204c can be pressed. The touch rod 204c drives the inclined block 204d to move. The inclined block 204d moves and squeezes the arc strip, so that the arc strip no longer fits on the gear 202e-1. At this time, the force storage bar 202e-2 instantly drives the gear 202e-1 to rotate, and the rotation of the gear 202e-1 drives the rotating wheel 203d to rotate. The rotating wheel 203d rotates and drives the rocking arm 203c to move, and the rocking arm 203c drives the slider 203a to move back and forth, and the slider 203a drives the cylinder 203b to move, wherein the cylinder 203b is located on the bottom side of the fixed plate, and the cylinder 203b reciprocates and contacts the bottom side of the fixed plate, so that the fixed plate vibrates, and the vibration of the fixed plate drives the filter plate 201c to vibrate. At this time, the staff turns the filter plate 201c upside down, and its vibration can shake off the attached coal blocks, which does not affect the subsequent use of the filter plate 201c.

[0044] Example 3

[0045] Reference Figure 5 and Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that: the backflow prevention unit 300 includes a pressing component 301 arranged on the water collecting component 201, and a closing component 302 is installed on the inner wall of the water collecting component 201. The pressing component 301 is connected to the closing component 302. When the pressing component 301 is pressed, the closing component 302 can be opened.

[0046] Specifically, the pressing assembly 301 includes a second contact pressure rod 301a disposed on the water collecting box 201a, and a movable connecting rod 301b installed at one end of the second contact pressure rod 301a.

[0047] Furthermore, the closing component 302 includes a receiving groove 302a arranged on the water outlet 201d, a rotating ring 302b is installed on the inner wall of the receiving groove 302a through a bearing, a sliding rod 302c is installed on the inner wall of the receiving groove 302a, a closing block 302d is installed at one end of the sliding rod 302c, a sealing gasket 302e is arranged on the closing block 302d, an arc block 302f is installed on the inner wall of the rotating ring 302b, and a fixing spring 302g is installed on the outer wall of the rotating ring 302b, and the fixing spring 302g is used to restore the rotating ring 302b, so that when the rotating ring 302b is restored, its arc block 302f can be pressed on the sliding rod 302c again, so that the movement of the sliding rod 302c drives the closing block 302d to move, so that the closing block 302d closes the water outlet 201d.

[0048] The rest of the structure is the same as that of Example 2.

[0049] Operation process: When the water collecting box 201a is in contact with the inner wall of the coal bunker, the second contact and pressure rod 301a drives the movable connecting rod 301b to move due to the contact pressure, and the movable connecting rod 301b drives the rotating circle 302b to rotate, and the rotating circle 302b rotates to drive the arc block 302f to move. After the arc block 302f moves, the sliding rod 302c is no longer contacted and pressed by the arc block 302f. At this time, the spring connected to the closing block 302d can pull the closing block 302d, so that the water outlet 201d closed by the four groups of closing blocks 302d is opened. At this time, the cleaned water can fall into the water outlet pipe 201e, and the second contact and pressure rod 301a does not When under pressure, the fixed spring 302g restores the rotating circle 302b, and the rotating circle 302b drives the arc block 302f to move. At this time, the arc block 302f moves to contact the slide bar 302c, and the movement of the slide bar 302c drives the closing block 302d to move. The closing block 302d closes the water outlet 201d again. When not cleaning, the pump body at the other end of the water outlet pipe 201e is closed. At this time, the water outlet pipe 201e extends from the top of the coal bunker to the inside of the coal bunker. At this time, the water in the water outlet pipe 201e will flow back due to gravity. At this time, the closing block 302d closes the water outlet 201d to prevent the backflow water from falling onto the stored coal.
