Furthermore, the suspended river treatment device further comprises a support seat 150, the two ends of the roll shaft 320 are rotatably connected with the support seat 150, and the support seat 150 plays a role in supporting the roll shaft 320. Preferably, the support seat 150 is a bearing seat.
An embodiment of the invention provides a suspended river treatment sand stirring boat which comprises the suspended river treatment device and a boat body, wherein the suspended river treatment device is installed on the boat body.
Specifically, the mud stirring piece 310 and the shower nozzle 410 spun injection fluid among the device are administered to the dangling river in this application can upwards bring riverbed silt to the upper strata in the rivers, then with the help of the power of rivers itself, carry silt to the low reaches region to can the efficient clear up riverbed silt, play the guard action to the environment, simultaneously, reduce the energy consumption loss.
In one embodiment, the axial direction of the roller 320 is coincident with the traveling direction of the ship hull, i.e. the axial direction of the roller 320 is along the traveling direction of the ship hull, and the steering power can be provided for the ship hull during the process that the sand stirring piece 310 lifts the riverbed sediment upwards.
Specifically, in the process that the sand stirring member 310 rotates in synchronization with the roller 320, the sand stirring rod 311 can be inserted into the riverbed sediment, and the hook 312 can catch a portion of the riverbed sediment and lift the caught riverbed sediment upward. In the process that the hook 312 catches and carries the riverbed sediment upwards, the hook 312 can receive the reverse acting force applied by the riverbed sediment, the axial direction of the roll shaft 320 is along the advancing direction of the ship body, the direction of the reverse acting force received by the hook 312 forms an angle with the advancing direction of the ship body, so that the posture adjustment can be provided for the ship body by the reverse acting force received by the hook 312 to provide steering power, and further, the energy consumption can be reduced. It should be noted that the traveling direction of the hull refers to a direction in which the hull travels along the flow direction of the water flow.
Furthermore, the number of the suspended river treatment devices is multiple, and the two suspended river treatment devices are respectively arranged on two side edges of the ship body in the advancing direction. When the ship body normally runs, the suspended river treatment devices on the two sides of the ship body along the advancing direction normally work, and the steering power provided by the suspended river treatment devices on the two sides to the ship body can be mutually offset, so that the ship body can normally run along the advancing direction; when the ship body needs to adjust the posture to steer, the rotating direction of the part of the driving pieces 210 can be changed, so that the steering force of one side of the ship body is larger than that of the other side of the ship body, the ship body adjusts the posture of the ship body through the obtained steering power, and the energy consumption is reduced.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
