[0027] The front and rear side walls of the inner cavity of the floating boat 1 are fixed with filter screen plates 23 which are equal in length to the sludge storage cavity 21. The filter screen plates 23 are made of stainless steel and have good filtering performance and corrosion resistance.

The filter screen plates 23 are arranged in an inclined downward manner, and the inclination angle of the filter screen plates 23 can be adjusted according to actual requirements, so as to ensure that the sludge is accumulated in the middle of the floating boat 1. The lower end surface of the filter screen plates 23 is fixedly connected with the bottom of the floating boat 1, and the lower ends of the two filter screen plates 23 are located on the front and rear sides of the screw conveyor 25, so that the middle part is located in the lowest depression, facilitating the deposition of sludge into the screw conveyor 25. The filter screen plates 23 are sealed with the floating boat 1 on four sides to prevent sludge from being discharged below the filter screen plates 23. The front and rear surfaces of the floating boat 1 are communicated with a plurality of drainage pipes 24 which are evenly and equidistantly distributed. The drainage pipes 24 are made of high-strength plastic material and are located below the filter screen plates 23 for re-discharging filtered sewage into the river.

[0028] The connecting plate 5 is provided with a traction assembly for pulling the floating boat 1 to the top.

The steel wire rope 34 passes between the guide wheels 33 to ensure stable transmission of the steel wire rope 34.

[0029] It should be noted that when the extension end of the telescopic rod 4 is in a fully extended state, the telescopic pipe 20 is in a fully extended state, and the hose 27 is in an incomplete straightened state. When the extension end of the telescopic rod 4 is in a fully retracted state, the telescopic pipe 20 is in a fully retracted state, and the hose 27 is in an incomplete straightened state. This ensures the telescopic cooperation effect of the telescopic rod 4 and the telescopic pipe 20, and avoids the hose 27 from being straightened and falling off during extension and retraction.

[0030] The working principle of the device is that, in use, through the connection of the telescopic rod 4, the connecting plate 5, the roller seat 6 and the floating boat 1, the floating boat 1 is driven to move along the middle part of the hardened river channel 2 in a straight line by using the rollers 7 on the roller seat 6 to roll in the track groove 3 on the hardened slope on both sides of the hardened river channel 2, avoiding the deviation of the sailing direction of the floating boat 1 caused by the influence of the water flow and the wind force when the floating boat 1 sails automatically; In the process of the floating boat 1 sailing in a straight line along the hardened river channel 2, the support frame 11, the telescopic pipe 20, the submerged sludge pump 35 and the hollow seat 16 are driven to move synchronously, and the telescopic rod 4 and the telescopic pipe 20 are set to expand and contract, so as to realize self-adaptive expansion and contraction support with the rising and falling of the river surface in the hardened river channel 2, and ensure that the hollow seat 16 moves in a straight line along the river channel with the floating boat 1; When the hollow seat 16 moves, the slope of the hollow seat 16 is set to avoid being blocked by the bottom sludge and affecting the movement of the hollow seat 16. In addition, when the hollow seat 16 moves, the driving motor 18 works to drive the crushing roller 19 to rotate, so as to crush the sludge and impurities in front in advance, avoiding the movement of the hollow seat 16 being blocked; With the movement of the hollow seat 16, the submerged sludge pump 35 works, the perforations 17 isolate large-particle obstacles, at the same time, the sludge enters through the perforations 17, is pumped out through the submerged sludge pump 35, and is discharged into the sludge storage cavity 21 through the mutual communication between the telescopic pipe 20 and the sludge discharge pipe 22 for storage; The sludge stored in the sludge storage cavity 21 is isolated by the filter screen plate 23, and the sewage is discharged through the filter holes of the filter screen plate 23 and is discharged into the river through the drain pipe 24. In addition, the inclined slope of the filter screen plate 23 ensures that the sludge is accumulated in the middle part of the floating boat 1, and the sludge enters the screw conveyor 25 through the feed inlet 26. When the sludge stored in the sludge storage cavity 21 needs to be cleaned, the electric push rod 8 is set to work to push the friction plate 9 to move, press and rub the roller 7, so as to lock and stabilize the roller 7 in the track groove 3; After being locked and stabilized, the servo motor 30 works to drive the winding disc 31 to rotate, and the guide wheel 33 synchronously drives the steel wire rope 34 to be guided and transmitted, so as to pull the floating boat 1 up after being stacked under the water surface, ensure that the hose 27 and the sludge discharge pipe 28 on the screw conveyor 25 form an inclined downward angle, facilitate the discharge of the sludge, and thus the inclined slope of the outer filter screen plate 23 ensures that the sludge is accumulated in the middle part of the floating boat 1, and the sludge enters the screw conveyor 25 through the feed inlet 26, so that the entering sludge is conveyed to the sludge discharge pipe 28 through the screw conveyor 25, realizes the automatic cleaning and discharge of the cleaned sludge from the floating boat 1 to the outside of the river channel, improves the cleaning efficiency, avoids the accumulation of the sludge in the floating boat 1 without being treated, and causes the cleaning work to be unable to continue. In addition, when the hollow seat 16 is difficult to move due to obstacles or needs to be maintained, the servo motor 12 is set to work to drive the winding disc 14 on the rotating shaft 13 to rotate, realizing the winding of the steel wire rope 15, pulling the hollow seat 16 to move upwards to bypass the obstacles, or pulling the hollow seat 16 to move upwards to the top for maintenance, and the telescopic pipe 20 synchronously extends and supports the hollow seat 16, ensuring the cleaning effect and the convenience of maintenance. In summary, the fixed route realizes automatic and comprehensive dredging of small river channels, ensuring the efficiency and effect of dredging.

[0031] Technical advantages, efficient dredging: through the straight-line movement of the floating boat 1 and the pumping action of the submerged sludge pump 35, the overall cleaning of the river sludge is realized, and the extension and contraction functions of the telescopic rod 4 and the telescopic pipe 20 ensure that the equipment adapts to water level changes and improves the dredging efficiency.

[0032] Intelligent control: the cooperation of the servo motor 30 and the traction assembly realizes the automatic traction and positioning of the floating boat 1, and the intelligent control system ensures the stable operation of the equipment in complex environments.

[0033] Sludge separation and treatment: the design of the filter screen plate 23 and the drain pipe 24 realizes the separation of sludge and sewage, reduces the volume of sludge, and improves the treatment efficiency, and the vertical conveying function of the screw conveyor 25 ensures the timely discharge of sludge and avoids accumulation.

[0034] Strong adaptability: the equipment is suitable for small hardening river channels and has strong flexibility, and the design of the telescopic rod 4 and the telescopic pipe 20 ensures that the equipment can stably operate at different water levels.

[0035] System control, using PLC (Programmable Logic Controller) or single-chip microcomputer as the core controller, has high reliability and powerful control function.

[0036] In summary, the intelligent support structure of the floating river dredging device significantly improves the efficiency and effect of river dredging through automatic sludge pumping, crushing, conveying and discharging functions, and through reasonable structural design, material selection and intelligent expansion, the device has wide application prospect in the field of river dredging and can effectively solve the problem of small river dredging.
