[0052] The lifting mechanism 4 is connected to the top of the belt conveyor 8 through the support frame 1, and the water absorption mechanism and the water absorption head 31 are connected through the first drainage pipe 3. The water absorption head 31 descends under the drive of the lifting end 421 of the lifting mechanism 4 to absorb the water on the belt conveyor 8.

When the belt conveyor 8 accumulates water next time, it only needs to drive the water absorption head 31 to descend through the lifting end 421 to absorb water, thereby realizing the repeated use of the drainage device, and there is no need to reinstall the drainage device each time water accumulates.

[0053] In this embodiment, the support frame 1 includes a horizontal beam 11 and two groups of vertical beams 12; the horizontal beam 11 is arranged above the belt conveyor 8, and the lifting mechanism 4 is fixedly connected to the horizontal beam 11; one end of the two groups of vertical beams 12 are respectively connected to the two sides of the middle frame 81 of the belt conveyor 8, and the other end is respectively connected to the two ends of the horizontal beam 11.

The lifting body 41 can provide telescopic power for the telescopic part 42, so that the lifting end 421 of the telescopic part 42 drives the water suction head 31 to descend to absorb water or ascend to store.

[0057] In this embodiment, the cross beam 11 is provided with a first through hole; one end of the lifting body 41 connected to the telescopic part 42 extends to the bottom of the cross beam 11 through the first through hole; the drainage device also includes a locking member 5, which is connected to the cross beam 11, located at the first through hole, and is detachably fixedly connected to the lifting body 41. The locking member 5 is used to detachably fix the lifting body 41, and can fix the lifting body 41 at different heights, and the fixed height of the lifting body 41 can be adjusted according to the distance between the cross beam 11 and the belt conveyor 8. The provision of the first through hole enables the lifting body 41 connected above the cross beam 11 to drive the telescopic part 42 to approach or move away from the belt 82 of the belt conveyor 8.

[0058] In this embodiment, the locking member 5 includes a base plate 51, at least two locking plates 52 and an ear plate 53. The base plate 51 is detachably fixedly connected to the top of the beam 11. The base plate 51 is provided with a second through hole coaxial with and matching the first through hole; an ear plate 53 is provided on both sides of each locking plate 52, at least two locking plates 52 are detachably connected through the ear plates 53 in sequence, and enclose a cylindrical space, the locking plates 52 are fixedly connected to the base plate 51, and the cylindrical space is coaxial with and matching the second through hole; the size of the cylindrical space can be changed by connecting the ear plates 53 to adapt to lifting bodies 41 of different sizes, and the lifting bodies 41 are clamped by at least two locking plates 52. The lifting body 41 includes a motor 411 and an extension part 412. One end of the extension part 412 is connected to the motor 411, and the other end passes through the cylindrical space, the second through hole and the first through hole in sequence to extend to the bottom of the crossbeam 11. The cylindrical space is suitable for interference fit with different heights of the extension part 412. At least two locking plates 52 are detachably connected in sequence through the ear plates 53, and different heights of the extension part 412 can be locked according to actual needs, so as to adjust the height of the lifting body 41 and then adjust the height of the telescopic part 42.

The arrangement of the vertical pipe section 32 and the horizontal pipe section 33 ensures that the first drainage pipe 3 will not be damaged due to repeated bending when it is lifted and lowered under the drive of the telescopic part 42 of the lifting structure, and the transition between the horizontal pipe section 33 and the hose 34 further reduces the bending damage during the lifting process. The vertical pipe section 32 and the horizontal pipe section 33 can be integrally formed, and the hose 34 can be directly connected to the horizontal pipe section 33 through a quick-insert structure. The cooperation between the slide rail 321 and the slide groove can limit the sliding direction of the vertical pipe section 32 to prevent the vertical pipe section 32 from tilting during the lifting process, resulting in uneven force. Specifically, the cross section of the slide rail 321 can be T-shaped, and the slide groove matches the shape of the slide rail 321. Alternatively, the slide groove can be a dovetail groove, and the cross section of the slide rail 321 matches the dovetail groove.

[0061] In this embodiment, the end of the telescopic portion 42 close to the water suction head 31 is connected to a rectangular tube 43, and the end of the rectangular tube 43 close to the water suction head 31 is detachably connected to the end of the vertical pipe section 32 close to the water suction head 31.

The bottom and both sides of the tape curtain 44 protrude from the clamping plate 45 and the rectangular tube 43 respectively. The fastener can be a fastening structure such as a bolt or a screw.

[0063] In this embodiment, a fixing ring 6 and a connecting piece 7 are further included, and the two ends of the connecting piece 7 are respectively connected to the side of the cross beam 11 and the outer periphery of the fixing ring 6, and the hose 34 is movably arranged in the fixing ring 6. The fixing ring 6 can limit the movement of the hose 34 to prevent the hose 34 from being entangled or bent during the movement. The inner wall of the fixing ring 6 is smooth and burr-free, and the hose 34 will not be damaged during the movement of the hose 34. The fixing ring 6 and the connecting piece 7 can have one group or multiple groups, and the number of the fixing rings 6 and the connecting piece 7 can be selected according to the length of the cross beam 11 between the lifting mechanism 4 and the water absorption structure 2.

[0065] In this embodiment, the water suction head 31 is made of rubber;

[0066] In this embodiment, the water suction mechanism includes a self-priming pump 21 connected to one end of the first drain pipe 3 away from the water suction head 31. The self-priming pump 21 applies corresponding suction to the water suction head 31 through the first drain pipe 3 to discharge the water accumulated on the belt conveyor 8; a check valve 22 is provided at one end of the first drain pipe 3 close to the water suction head 31 to prevent water from flowing back from the water suction head 31 to the belt conveyor 8.

[0067] In this embodiment, a filter 23 is provided in the water suction head 31, or a filter 23 is provided at one end of the first drain pipe 3 close to the water suction head 31.

[0068] like Figure 1 and Figure 2 As shown, in one implementation of this embodiment, the water suction mechanism includes a self-priming pump 21 and a second drain pipe 24 connected to the water outlet end of the self-priming pump 21; the self-priming pump 21 absorbs water through the first drain pipe 3 and the water suction head 31, and discharges the water to an external water collection device through the second drain pipe 24.

[0069] The drainage process of the drainage device of the belt conveyor 8 of this embodiment includes: opening the lifting mechanism 4, the telescopic part 42 is extended, the lifting end 421 drives the water suction head 31, the vertical pipe section 32 and the horizontal pipe section 33 to descend to approach the lowest point of the belt conveyor 8, the hose 34 moves along the fixed ring 6, and the self-priming pump 21 is turned on to absorb water; after most of the accumulated water is sucked away, the belt conveyor 8 can be turned on, the tape curtain 44 cooperates with the tape 82 of the belt conveyor 8 to scrape water, and the water is gathered at the water suction head 31, and is sucked away by the water suction head 31. After the water absorption is completed, the belt conveyor 8 and the self-priming pump 21 are turned off, the lifting mechanism 4 is turned on, the telescopic part is shortened, the lifting end 421 drives the water suction head 31, the vertical pipe section 32 and the horizontal pipe section 33 to rise to be stored at the crossbeam 11, and the hose 34 moves along the fixed ring 6.

The water storage tank 27 can store water and provide a sufficiently large negative pressure during the drainage process to ensure a better drainage effect. The control logic of the lifting mechanism 4 and the belt conveyor 8 of the water absorption mechanism using the siphon effect is the same as that of the water absorption mechanism using the self-priming pump 21 to absorb water, and will not be repeated here.

[0072] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
