[0066] The present application also discloses a method for dredging. Figure 6 , dredging methods include:

[0067] S10: Obtain the sewage pool specification information and the silt suction range information of the suction head, and determine the silt removal position information of the bottom of the sewage pool.

[0068] Specifically, the sewage pool specifications are obtained from the sewage pool construction data, including the length, width, bottom area, depth and other data of the sewage pool; then, based on the power of the centrifugal pump and the size of the suction head, the silt suction range of the suction head is obtained through experiments; then, the bottom area of ​​the sewage pool in the sewage pool specifications and the silt suction range of the suction head are used to divide and determine the various dredging positions at the bottom of the sewage pool.

[0069] S20: Calculating the maximum inclination angle information of the free hose section before the suction head reaches each desilting position according to the sewage pool specification information and each desilting position information.

[0070] In this embodiment, the maximum inclination angle of the free hose section refers to the inclination angle of the free hose section that improves the smoothness of the movement of the suction head along the movable base while preventing the suction head from hitting the wall of the sewage pool when reaching the desilting position.

[0071] Specifically, based on the width and depth data in the sewage pool specifications and each dredging position, the maximum inclination angle of the free hose section before the suction head reaches each dredging position is calculated. Whenever the suction head is moved to a dredging position, the inclination angle of the free hose section is kept smaller than the maximum inclination angle to improve the smoothness of the movement of the suction head.

[0072] S30: triggering a dredging instruction according to the dredging position information and the maximum inclination angle information of the free hose section.

[0073] Specifically, after obtaining each dredging position and the maximum inclination angle of the free hose section, the dredging instruction is triggered, and the first drive component and the second drive component drive the movable seat to move to a position directly above each dredging position. In the process of movement, the driving component causes the suction head to swing with the free hose section and remain at a position less than the maximum inclination angle.

[0074] S40: Obtaining mud and water concentration information in the connection section, and determining whether the mud and water concentration is less than a predetermined threshold.

[0075] In this embodiment, the predetermined threshold value refers to a value used to determine whether the silt at the silt removal location has been completed.

[0076] Specifically, the mud and water concentration in the connecting section is detected in real time by a sludge concentration meter to obtain the mud and water concentration in the connecting section, and then the mud and water concentration is compared with a predetermined threshold to determine whether the mud and water concentration is less than the predetermined threshold, that is, to determine whether the sludge at the dredging location has been cleaned.

[0077] S50: If yes, trigger a stop instruction.

[0078] Specifically, if it is determined that the mud-water concentration is less than a predetermined threshold, that is, it is determined that the silt at the silt removal location has been cleared, a stop instruction is triggered to stop the centrifugal pump.

[0079] In one embodiment, referring to Figure 7 The method of step S20 includes:

[0080] S21: According to the sewage pool specification information, the depth information of the sewage pool is obtained, and the total length information of the suction head after being installed in the free hose section is determined.

[0081] Specifically, the depth of the sewage pool is obtained from the sewage pool specifications, and then the total length of the suction head after being installed in the free hose section is determined based on the position of the movable seat, that is, the distance between the movable seat and the bottom of the sewage pool. The straight line formed is one of the right-angled sides.

[0082] S22: According to the desilting position information, obtain the horizontal distance information between the desilting position and the sewage pool wall in the forward direction of the moving seat.
