DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] Embodiment one:

[0028] With reference to Figure 1 , the present application provides an embodiment: a dredging device for limited space, comprising a concrete well body 7, a pipe body support 6 is installed at the top of the concrete well body 7, a spiral pipe body 4 is fixedly connected to the inner side of the pipe body support 6, a cover 2 is fixedly connected to the top of the spiral pipe body 4, a motor 1 is fixedly connected to the top of the cover 2, the output end of the motor 1 penetrates through the cover 2 and is fixedly connected with a bearing one 3, a discharge pipe 5 is communicated with the outer wall of the pipe body support 6, pipelines 9 are installed on the left and right sides of the inside of the concrete well body 7, a bearing two 11 is installed at the bottom of the spiral pipe body 4, and a bearing support 12 is installed on the outer side of the bearing two 11; the inside of the pipeline 9 is provided with well internal sediment 10;

[0029] Specifically, when performing dredging operation in limited space, the motor 1 is started to drive the bearing one 3 and the spiral blades built in the spiral pipe body 4 to rotate. In this process, the well internal sediment 10 is introduced into the pipeline 9 and contacted with the inside of the spiral pipe body 4, and then transported upward by the rotating action of the spiral blades. When the well internal sediment 10 reaches the position of the discharge pipe 5, it is automatically discharged through the pipeline 9. This dredging process realizes automatic operation, effectively reduces the safety hidden trouble in the operation process, and significantly improves the work efficiency.

[0030] Embodiment two:

[0031] With reference toFigure 2 、 Figure 3 and Figure 4 The top of the concrete well body 7 is provided with a fixed support 13, the outer side of the fixed support 13 is rotatably connected with a support hinge 19, the outer side of the support hinge 19 is provided with a movable support 16, one side of the movable support 16 is provided with a movable bolt 15, the other side of the fixed support 13 is provided with a fixed socket 14, the fixed socket 14 is slidably connected with the movable bolt 15, the outer wall of the fixed support 13 is provided with a fixed cylinder 18, the inner side of the fixed cylinder 18 is provided with a working cylinder 17; the bottom of the movable support 16 is provided with a movable wheel 20;

[0032] Specifically, the movable wheel 20 is operated to drive the movable support 16 to move. In this process, the movable support 16 and the fixed support 13 will rotate relative to each other, and the support hinge 19 will also rotate. This series of actions aims to make the movable support 16 and the fixed support 13 tightly merge.
