The structures of the moving mechanism 10, the sludge treatment mechanism 20, and the self-generating mechanism 30 will be described in detail below.

As shown in fig. 2, the moving mechanism 10 includes a tracked vehicle 12 and a lifting seat 14, the lifting seat 14 is disposed on the tracked vehicle 12, and the sludge treatment mechanism 20 is connected to the lifting seat 14 and is driven by the lifting seat 14 to perform lifting movement.

Specifically, the tracked vehicle 12 is used for moving along the river 210 under the action of external force, and the tracked vehicle 12 can move on uneven ground, so that the movement stability of the sludge treatment mechanism 20 can be improved by arranging the tracked vehicle 12 for moving on the river 210. Alternatively, other types of wheeled carts may be used to move the sludge treatment mechanism 20.

The lifting seat 14 is disposed on the crawler 12, and the sludge treatment mechanism 20 can be disposed at the lifting end of the lifting seat 14, so that the height of the sludge treatment mechanism 20 relative to the river bed 220, that is, the height relative to the sludge, can be adjusted by the lifting seat 14, so as to clean the sludge with different thicknesses. Alternatively, the lifting base 14 may be a common telescopic motion mechanism such as an air cylinder, a hydraulic cylinder, or a telescopic rod, and the structure of the lifting base 14 will not be described in detail in the present invention.

As shown in fig. 2 and 3, fig. 3 is a partially enlarged schematic structural diagram of a circle a in fig. 2. The sludge treatment mechanism 20 comprises a floating frame 21, a transmission chain 22 and a cutter head 23. The transmission chain 22 is arranged on the floating frame 21 and can move under the action of the driving piece 26; the cutter head 23 is arranged on the transmission chain 22 and is used for digging sludge in the river 210.

Specifically, the floating frame 21 is used to float on the water surface to support the sludge treatment mechanism 20 above the sludge for facilitating the cleaning operation of the sludge treatment mechanism 20. The floating frame 21 can be made of foam with a smaller density, for example, so that the weight of the sludge treatment mechanism 20 can be reduced, and the moving mechanism 10 can drag the sludge treatment mechanism 20 to move conveniently; on the other hand, the sludge treatment mechanism 20 can be provided with larger buoyancy, so that the cutter head 23, the self-generating mechanism 30 and the like with larger weight can be arranged conveniently. Optionally, the floating frame 21 may be provided with a plurality of hollows, so that not only the weight of the floating frame 21 can be reduced, but also the resistance of the floating frame 21 to water flow can be reduced, and the moving mechanism 10 can drag the floating frame 21 to move conveniently.

Further, as shown in fig. 2 and 3, the sludge treatment mechanism 20 may be provided to include a plurality of floating blocks 24, and the floating blocks 24 are attached to the floating frame 21. The floating block 24 can be used for providing buoyancy for the floating frame 21, and when the water level changes and the sludge height changes, the floating block 24 can enable the floating frame 21 to float above the water surface so as to provide support for the cutter head 23, and at the moment, the cutter head 23 is just inserted into the sludge so as to clean the sludge by the cutter head 23.

Alternatively, the cross-sectional dimension of the side of the float block 24 close to the river bed 220 may be smaller than the cross-sectional dimension of the side of the float block 24 away from the river bed 220, for example, a chamfer or a fillet or the like may be provided on the side of the float block 24 close to the river bed 220 to reduce the abutting area of the float block 24 with the sludge, so as to facilitate the insertion of the cutter head 23 into the sludge.

When the driving chain 22 moves, the cutter head 23 can be driven to move to be close to the river channel 210, so that the sludge dug by the cutter head 23 can be conveniently recycled, and the next digging is convenient.

If the connecting piece that will connect tool bit 23 and driving chain 22 sets up great, though can make the position of tool bit 23 more stable, avoid digging the in-process of getting mud and driving chain 22 and carry out the in-process that removes and rock, but can make the structure of connecting piece comparatively complicated, so, in this embodiment, adopt pin etc. to rotate tool bit 23 and driving chain 22 and be connected.

So, set up slider 232 and the spout 252 of mutually supporting, can utilize the spout 252 to lead and spacing for slider 232 for tool bit 23 only can follow the extending direction of spout 252, and the direction of motion of driving chain 22 moves promptly, and can not take place to rock or rotate, thereby has promoted the stationarity of tool bit 23 motion.

Alternatively, the drive chain 22 may be arranged to reciprocate in one direction to reciprocate the cutter head 23. Specifically, when the transmission chain 22 drives the cutter head 23 to enter the riverbed 220, the cutter head 23 can dig sludge, then the transmission chain 22 drives the cutter head 23 to move towards the direction close to the river 210, so as to clean the sludge in the cutter head 23, and the cleaned cutter head 23 enters the riverbed 220 again under the action of the transmission chain 22. Although the sludge can be cleaned, the cleaning efficiency is low.

Therefore, the transmission chain 22 can be arranged in an annular shape, a plurality of cutter heads 23 are arranged, the cutter heads 23 are arranged on the transmission chain 22 at intervals, and the driving piece 26 can drive the transmission chain 22 to do circular rotation motion. The cutter head 23 close to one side of the river bed 220 can move to the position close to the river bed 220 under the driving of the transmission chain 22 after digging sludge, when the cutter head 23 moves along the end part of the transmission chain 22, under the action of gravity, the sludge borne in the cutter head 23 can fall under the action of gravity, so that the recovery mechanism can recover, the cutter head 23 can move to the upper part of the transmission chain 22 under the action of the transmission chain 22 and move towards the direction close to the river bed 220, and after the end part of the transmission chain 22 deviating from the river bed 220 rotates, the sludge enters the river bed 220 again to dig sludge, so that the digging efficiency of the sludge can be improved.

Therefore, in the present embodiment, as shown in fig. 3 and 4, fig. 4 is a partially enlarged schematic view of a cross-sectional structure of the tool bit and the carriage in an embodiment of the present application. A rack 254 may be provided in the chute 252, the transmission assembly 235 may include a first rotation shaft 2352, a second rotation shaft 2354, a first bevel gear 2356 and a second bevel gear 2358, the first rotation shaft 2352 is slidably disposed on the sliding rack 234, a gear 2351 engaged with the rack 254 is disposed on the first rotation shaft 2352, when the sliding rack 234 moves, the first rotation shaft 2352 rotates under the action of the gear 2351, the first bevel gear 2356 is disposed on the first rotation shaft 2352, an axis of the second rotation shaft 2354 is perpendicular to an axis of the first rotation shaft 2352, the second bevel gear 2358 is disposed on the second rotation shaft 2354 and is engaged with the first bevel gear 2356, and the plurality of mud buckets 236 are connected to an end of the second rotation shaft 2354 and are disposed around an axis of the second rotation shaft 2354.

When the driving chain 22 drives the sliding frame 234 to slide in the sliding groove 252, the gear 2351 and the rack 254 are matched with each other, so that the rotation of the gear 2351 is converted into the rotation of the first rotating shaft 2352, and then the rotation is transmitted to the second rotating shaft 2354 through the first bevel gear 2356 and the second bevel gear 2358 which are engaged with each other, so as to drive the second rotating shaft 2354 to rotate, and further drive the mud buckets 236 connected to the second rotating shaft 2354 to rotate, and thus, the driving part 26 for driving the mud buckets 236 to rotate can be saved, and energy consumption can be saved.

Optionally, as shown in fig. 3 and 4, a plurality of filtering holes 2362 may be provided on the bagger 236, on one hand, the resistance of the water flow to the bagger 236 may be reduced, so as to facilitate the rotation of the bagger 236, and on the other hand, the water may be filtered, and only the sludge may be dug.

Further, as shown in fig. 2 and 5, fig. 5 is a partial structural view at circle B in fig. 2. The self-generating mechanism 30 includes an impeller 31, a generator 32, and a super capacitor 33. The generator 32 is in transmission connection with the impeller 31, and the generator 32 is used for converting the rotation of the impeller 31 into electric energy; the super capacitor 33 is electrically connected to the generator 32 for storing the electric energy converted by the generator 32.

Specifically, the impeller 31 may be connected to the floating frame 21 and sink in water, when water flows through the impeller 31, the impeller 31 is driven to rotate, the impeller 31 drives the generator 32 to generate electricity when rotating, electric energy generated by the generator 32 is stored in the super capacitor 33, when the storage of the super capacitor 33 is completed, the electric energy can be discharged in a short time, the super capacitor 33 is electrically connected to the driving member 26 of the driving transmission chain 22, and then supplies power to the driving member 26 to drive the driving transmission chain 22 to move. Through set up impeller 31 on floating frame 21 to can utilize rivers to generate electricity, store the electric energy in super capacitor 33, and be used for supplying power for sludge treatment mechanism 20, can realize river course sludge treatment device 100's self-power, solve river course sludge treatment device 100 power consumptive great, not energy-concerving and environment-protective problem.

As shown in fig. 5, the impeller 31 includes an impeller shaft 312 and a plurality of impeller blades 314, wherein the impeller blades 314 are disposed at one end of the impeller shaft 312 and are disposed around an axis of the impeller shaft 312 for driving the impeller shaft 312 to rotate under the action of water flow.

Through setting up the torsional spring 34 of connecting in impeller axle 312 and shell gear 35, can drive shell gear 35 through impeller axle 312 and rotate on the one hand, on the other hand when impeller axle 312 is great at impeller blade's drive down rotational speed, torsional spring 34 also can cushion impeller axle 312's effort, and then makes shell gear 35's operation more steady, avoids shell gear 35's rotation too fast and damages motor shaft 322.

Further, in order to increase the rotation speed of the motor shaft 322, as shown in fig. 2 and 5, the self-generating mechanism 30 may include a transmission belt gear 36 and a transmission belt 37, the transmission belt gear 36 is engaged with the housing gear 35, the number of teeth of the transmission belt gear 36 is smaller than that of the housing gear 35, and the transmission belt 37 is sleeved on the transmission belt gear 36 and the motor shaft 322 of the generator 32. The number of teeth through setting up drive belt gear 36 is less than shell gear 35's number of teeth, and when shell gear 35 rotated, drive belt gear 36's slew velocity was greater than shell gear 35's slew velocity to utilize drive belt gear 36 to accelerate shell gear 35, and then promote the rotational speed of motor shaft 322 who is connected with drive belt gear 36, promote generator 32's generating efficiency.

When the direction of the water flow changes, the impeller 31 can rotate in the reverse direction, and then the housing gear 35, the transmission belt gear 36 and the motor shaft 322 are driven to rotate in the reverse direction, and the generator 32 is damaged.
