[0003] The situation in cleaning sludge in urban rivers and culverts is quite changeable, especially in some situations far away from urban roads where large engineering vehicles cannot enter. Generally, the sludge can only be transported by human-powered carts, or by a combination of small excavators and engineering vehicles. Due to the large amount of river sludge cleaning construction work, the above-mentioned sludge cleaning methods have low work efficiency and long construction periods, and cannot meet the requirements of efficient urban river sludge cleaning construction operations.

The floating silt removal device 100 can float on the upper surface of the silt in the river channel 60 through the arrangement of the buoy 10, which increases the mobility of the floating silt removal device 100. The structure of the floating silt removal device 100 is simplified through the connection frame 11 and the first mud pump 12 arranged above the connection. The mud tanker 30 and the first mud pump 12 are connected through the sewage pipe 50, which effectively expands the radiation range of silt cleaning and discharge, and can cope with silt cleaning operations in the river channel 60 under different circumstances. The high-pressure water spraying device around the floating silt removal device 100 makes the cleaning of the silt in the river channel 60 more thorough, which is conducive to improving the silt cleaning efficiency. In an exemplary example, the floating silt cleaning system also includes a first plugging plate 61 and a second plugging plate 62, which are relatively arranged at two nodes of the river channel 60 for intercepting the river channel 60, and the floating silt removal device 100 is arranged between the first plugging plate 61 and the second plugging plate 62. The provision of the first plugging plate 61 and the second plugging plate 62 is conducive to the segmented treatment of the sludge in the river channel 60 and the culvert.

[0028] In one embodiment, a floating sludge cleaning system is provided, wherein two buoys 10 are provided, the two buoys 10 are arranged in parallel and spaced apart, and the two parallel buoys 10 are fixedly connected by a connecting frame 11, the connecting frame 11 comprises a middle connecting rod 111 and a top connecting rod 112, the two middle connecting rods 111 are provided, the two middle connecting rods 111 are arranged in parallel between the two buoys 10, the ends of the middle connecting rods 111 are connected to the middle of the buoy 10, and are arranged perpendicular to the central axis of the buoy 10; there are two top connecting rods 112, the two top connecting rods 112 are arranged in parallel at the top of the buoy 10, the two ends of the top connecting rod 112 are fixedly connected to the top of the buoy 10, the top connecting rod 112 is arranged perpendicular to the axial direction of the buoy 10, preferably, a fixing rod parallel to the axial direction of the buoy 10 is also provided between the two middle connecting rods 111 (not shown in the drawings), and a fixing rod parallel to the axial direction of the buoy 10 is provided between the two top connecting rods 112, and the fixing rod is used to increase the stability of the connecting frame 11 structure. Of course, in other applicable embodiments, the number of the middle connecting rods 111 and the top connecting rods 112 is adjusted and set according to the size of the buoy 10. By setting the middle connecting rods 111 and the top connecting rods 112, the buoy 10 is stably connected to form a stable supporting platform of the floating dredging device 100. At the same time, the middle connecting rod 111 arranged in the middle of the buoy 10 can effectively avoid the silt at the bottom of the river channel 60 and the culvert, thereby increasing the flexibility of the floating dredging device 100. In an exemplary embodiment, for the convenience of the operation of the first mud pump 12, the first mud pump 12 is fixedly connected to the top connecting rod 112 through a fixing plate 123. The fixing plate 123 can be detachably fixedly connected to the top connecting rod 112 by fasteners, so as to adjust the inclination angle of the first mud pump 12 according to the sludge cleaning construction conditions, or the fixing plate 123 can be welded and fixed to the top connecting rod 112 after the first mud pump 12 is adjusted to a suitable angle.

That is, the first water pump 71 is arranged upstream or downstream of the plugging interval, which is convenient for taking water nearby, and the high-pressure water flow sprayed by the first nozzle 72 impacts the sludge, thereby improving the working efficiency of the first mud pump 12. Preferably, the high-pressure water spraying device also includes a second high-pressure water spraying device 80, the second high-pressure water spraying device 80 includes a second water pump 81 arranged outside the first plugging plate 61 or the second plugging plate 62, and a second nozzle 82 connected by a water pipe, and the second nozzle 82 is arranged on the river bank on the other side of the floating dredging device 100. By relatively setting high-pressure water spraying devices on both sides of the river channel 60 and the culvert, a wider range of scouring can be formed for the silt at the bottom of the river channel 60 and the culvert, thereby avoiding cleaning dead corners, increasing the cleaning effect of the silt, and improving the silt cleaning efficiency.

[0030] like Figure 1-3 As shown, the embodiment of the present invention also relates to a sludge cleaning method, comprising the following steps:

[0031] The first blocking plate 61 and the second blocking plate 62 are used to block and intercept the river channel 60; a blocking area is formed between the first blocking plate 61 and the second blocking plate 62, which is conducive to concentrated operations in the blocking area and prevents interference with water flow in the river channel 60 and the culvert.

[0032] Place the floating silt removal device 100 described in any one of the above items in the river channel 60 between the first blocking plate 61 and the second blocking plate 62;

[0033] One end of the sewage pipe 50 is connected to the discharge port 122 of the first mud pump 12, and the other end is connected to the container of the mud tanker 30.

[0034] A high-pressure water spraying device is arranged on the river bank around the floating silt removal device 100. In an exemplary example, the high-pressure water spraying device includes a first high-pressure water spraying device 70 and a second high-pressure water spraying device 80, which are arranged on the river banks on both sides of the floating silt removal device 100, and can spray high-pressure water flow toward the silt in the river channel 60 around the floating silt removal device 100. Through the first high-pressure water spraying device 70 and the second high-pressure water spraying device 80, the silt at the bottom of the river channel 60 and the culvert can be flushed in a wider range, avoiding cleaning dead corners, increasing the cleaning effect of the silt, and improving the silt cleaning efficiency.

[0035] During the sludge cleaning construction of a 2.1km culvert, due to the complex terrain on both sides of the culvert and the long distance from the urban roads, it is inconvenient for large construction vehicles to enter, and the culvert is about 20km away from the sludge treatment center. According to the conventional technical means in the prior art, the sludge is transported by a human-powered cart, and the sludge cleaning and transportation construction cycle is 45 days using a combination of a small bucket truck and an engineering vehicle.

The construction period of 2.1km culvert sludge cleaning is shortened to 15 days, the efficiency is significantly improved, and the construction cost is also effectively reduced.

[0036] The floating silt cleaning system and silt cleaning method provided by the present invention enable the floating silt cleaning device to float on the upper surface of the river silt through the arrangement of the buoy, thereby increasing the mobility of the floating silt cleaning device; the structure of the floating silt cleaning device is simplified through the connection frame and the first slurry pump arranged above the connection; the arrangement of the mud tanker and the first slurry pump connected by the sewage pipe effectively expands the radiation range of silt cleaning discharge, and can cope with river silt cleaning operations in different situations; the arrangement of the high-pressure water spraying device around the floating silt cleaning device makes the cleaning of the river silt more thorough The bottom is conducive to improving the sludge cleaning efficiency; by setting the second mud pump in the middle of the sewage pipe, the transmission distance of the river sludge cleaning discharge is effectively increased, which can realize the efficient cleaning of the river and culvert sludge far away from the urban roads, expand the application scope of the floating sludge cleaning system, and improve the sludge cleaning efficiency; through the setting of large-volume mud tankers and long-distance sewage pipes, it can effectively cope with the cleaning operations of rivers and culverts far away from urban roads, reduce the frequency of transportation equipment to and from the sludge treatment center during the sludge cleaning process, effectively save transportation time, and improve the efficiency of sludge cleaning construction.
