For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, an urban river and ditch water cleaning device includes an overhead crane 1 for position adjustment and a sludge extraction mechanism 2 provided on the overhead crane 1. The overhead crane 1 in this embodiment is a commonly used hoisting component, directly using commercially available equipment without any modification, and will not be described in detail here.

[0032] like Figure 2-Figure 3 As shown, the sludge extraction mechanism 2 includes an adjustable sealing cover 21, on which a stirring assembly 22 and a suction assembly 23 are provided. The sewage pipe 231 of the suction assembly 23 is provided on the overhead crane 1 and is arranged opposite to the telescopic conveyor 3 on the overhead crane 1.

[0033] The adjustable sealing cover 21 includes a fixed cover body 211 and a rotating cover body 212, which are rotatably connected to the rotating cover body 212, and a water inlet hole 213 is opened on the fixed cover body 211 and the rotating cover body 212. An adjustment drive motor 215 is provided on the fixed cover body 211, and the output shaft of the adjustment drive motor 215 is engaged with the adjustment gear ring 214 on the rotating cover body 212 through a gear. By adjusting the rotation angle of the rotating cover body 212, the relative degree of the water inlet holes 213 of the fixed cover body 211 and the rotating cover body 212 is achieved. When entering water, the water inlet holes 213 of the two are arranged relative to each other, so that water in the water body can enter the adjustable sealing cover 21. When stirring and diluting are performed, the water inlet holes 213 of the two are staggered, so that the silt surface and the adjustable sealing cover 21 form a certain sealing structure, so that the diluted and stirred sewage will not enter the water body.

[0034] The stirring assembly 22 includes a stirring hollow shaft 221, such as Figure 4As shown, the stirring gear ring 222 on the outside of the stirring hollow shaft 221 is engaged with the gear on the stirring drive motor 223 on the fixed cover 211 to realize the rotation of the stirring hollow shaft 221. The stirring hollow shaft 221 is provided with a stirring hollow blade 224, and the stirring hollow blade 224 is provided with a sewage outlet 225, and the diluted sewage can enter the stirring hollow shaft 221 through the stirring hollow blade 224. The sewage outlet 225 is provided with an anti-blocking component 24, such as Figure 5 As shown, the anti-blocking assembly 24 includes a plurality of circumferentially distributed connecting springs 241. One end of the connecting spring 241 is disposed in a blind hole of the mixing hollow blade 224. The other end of the connecting spring 241 is connected to an anti-blocking plate 242. An insert rod 243 is disposed inside the anti-blocking plate 242. When the connecting spring 241 is compressed or returned to its original position, the insert rod 243 moves back and forth in the sewage outlet 225 to prevent silt from blocking the sewage outlet 225. The suction assembly 23 includes a sewage suction pump 232, which is mounted on the fixed cover 211. The sewage suction pipe of the sewage suction pump 232 is connected to the mixing hollow shaft 221 via a rotary joint to discharge the diluted sewage. The regulating drive motor 215, the mixing drive motor 223, and the sewage suction pump 232 are circumferentially distributed on the top of the fixed cover 211, so that the gravity distribution is more uniform.

[0035] The telescopic conveyor 3 is a telescopic conveyor 3, one end of the telescopic conveyor 3 is slidably connected to the support frame of the overhead crane 1, and the other end of the telescopic conveyor 3 is connected to the moving part of the overhead crane 1, and the belt of the telescopic conveyor 3 is provided with a water filter hole to achieve preliminary filtration and transportation.

[0036] In order to continue to move into the silt after touching the bottom, a vibration ring 4 is provided outside the fixed cover 211, and the vibration ring 4 is mounted on the outside of the fixed cover via a number of vibration springs 5. The vibration generated during the stirring or suction process further affects the vibration ring 4, causing the adjustable sealing cover to move downward.

[0037] Based on the above-mentioned cleaning method of the urban river ditch water body cleaning device, the specific steps are as follows:

[0038] Step S1: erecting the overhead crane 1 on the water body to be cleaned and installing the telescopic conveyor 3 .

[0039] Step S2: The adjustable sealing cover 21 is lowered to the desilting position by the overhead crane 1 . At this time, the water inlet holes 213 of the fixed cover body 211 and the rotating cover body 212 are arranged opposite to each other.

[0040] Step S3: starting the adjustment drive motor 215 to rotate the rotating cover 212 to a set angle, so that the water inlet holes 213 of the fixed cover 211 and the rotating cover 212 are staggered, and the adjustable sealing cover 21 is in a sealed state.

[0041] Step S4: Start the stirring drive motor 223 to stir and dilute the sludge.

[0042] Step S5: After stirring for a set time, start the sewage suction pump 232 to pump the diluted sewage to the telescopic conveyor 3 for discharge. The vibration generated during the stirring, dilution and sewage suction process causes the adjustable sealing cover 21 to move downward continuously, increasing the cleaning depth.

[0043] Step S6: After the cleaning is completed, the overhead crane 1 is started to move the adjustable sealing cover 21 to the next cleaning position.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
