[0026] The following will describe the present utility model in detail with reference to the accompanying drawings: According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present utility model.

[0027] Please refer to Figures 1 to 4, an embodiment of the present utility model provides a water-absorbing and swelling flood control sandbag stacking device 10, which includes a flood control support 100 and a group of flood control sandbags 200 thereon. The flood control support 100 includes a vertical support 101 and a plurality of rear struts 102 obliquely connected thereto. Side plates 105 are provided between the vertical supports 101 on both sides and the rear struts 102. A flood control plate 106 is vertically provided upward at the lower end of the vertical support 101. The height of the flood control plate 106 is lower than that of the vertical support 101. A tray 115 is vertically provided on the flood control plate 106. A driving shaft 108 is rotatably connected between the side plates 105. A sleeve 109 is fixedly provided on the driving shaft 108. A rotating handle 110 is provided on the driving shaft 108 outside the side plates 105. A fixed shaft 111 parallel to the driving shaft 108 is fixedly provided between the side plates 105. A movable roller 112 is rotatably provided on the fixed shaft 111; the group of flood control sandbags 200 includes water-absorbing and swelling flood control sandbags 201 arranged in an alternating pattern of odd and even numbers. Adjacent two rows of the water-absorbing and swelling flood control sandbags 201 are connected by a flexible rope 202. The group of flood control sandbags 200 is stacked layer by layer in the tray 115. The first row of the group of flood control sandbags 200 is pulled out from the tray 115 and passed through between the sleeve 109 of the driving shaft 108 and the movable roller 112 of the fixed shaft 111. By rotating the rotating handle 110, the driving shaft 108 and the sleeve 109 thereon and the movable roller 112 of the fixed shaft 111 move in opposite directions to squeeze and roll out the group of flood control sandbags 200 and slide down along the guide of the flood control plate 106 to be stacked layer by layer in front of the flood control plate 106 to form a flood control dike, that is, the water-absorbing and swelling flood control sandbags 201 are stacked layer by layer in an alternating pattern to form a flood control wall.

[0028] The sleeve 109 can be one not greater than the length of the driving shaft 109, or can be a plurality of sleeves spaced apart on the driving shaft 109. The movable roller 112 can be one not greater than the length of the fixed shaft 112, or can be a plurality of movable rollers spaced apart on the fixed shaft 112. The length of the tray 115 is the same as that of the vertical support 101. The alternating arrangement of odd and even numbers of the water-absorbing and swelling flood control sandbags 201 in each row includes, but is not limited to, the arrangement rule of 3-2-3-2. Adjacent two rows of the water-absorbing and swelling flood control sandbags 201 are arranged in an alternating pattern of odd and even numbers. The advantage is that when adjacent two rows of the water-absorbing and swelling flood control sandbags 201 are stacked layer by layer, the adjacent two layers of the water-absorbing and swelling flood control sandbags 201 are directly stacked in an alternating pattern, improving the water blocking effect. The layer-by-layer stacking by row means that one row corresponds to one layer. The flexible rope 202 can connect adjacent two rows of the water-absorbing and swelling flood control sandbags 201 together, so that each row of the water-absorbing and swelling flood control sandbags 201 forms a whole. Moreover, connecting adjacent two rows of the water-absorbing and swelling flood control sandbags 201 together by the flexible rope 202 is beneficial to the stacking control of each row of the water-absorbing and swelling flood control sandbags 201.

[0029] The water-absorbing and swelling flood-control sandbag stacking device 10 provided by the embodiment of the present utility model places the flood-control support 100 at the place to be flood-controlled.

The first row of the stacked flood-control sandbag group 200 is pulled out and passed through between the sleeve 109 of the driving shaft 108 and the movable roller 112 of the fixed shaft 111. By rotating the rotary handle 110, the driving shaft 108 and the sleeve 109 thereon and the movable roller 112 of the fixed shaft 111 move in opposite directions, so that the flood-control sandbag group 200 is extruded and rolled out, and slides down along the flood-control board 106 and is stacked layer by layer in front of the flood-control board 106 to form a flood-control dike. The flood-control dike swells after encountering water to block the water. Through the cooperation of the flood-control dike and the flood-control board 106 of the flood-control support 100, the stability of the flood-control dike can be improved, and the possibility of displacement of the built flood-control dike caused by the impact of water flow can be reduced, thereby improving the water-blocking rate of flood control.

[0030] The water-absorbing and swelling flood-control sandbag stacking device 10 provided by the embodiment of the present utility model stacks the water-absorbing and swelling flood-control sandbags 201 layer by layer in rows by arranging them in odd and even numbers and connecting them with a flexible rope 202 to form a flood-control sandbag group 200. Then, through the driving shaft 108 of the flood-control support 100 and the sleeve 109 thereon and the movable roller 112 of the fixed shaft 111 moving in opposite directions, the flood-control sandbag group 200 is extruded and rolled out, and slides down along the flood-control board 106 and is stacked layer by layer in front of the flood-control board 106 to form a flood-control dike. Compared with manually carrying the water-absorbing and swelling flood-control sandbags 201 independently and stacking them layer by layer in a staggered manner at the place to be flood-controlled to form a flood-control dike, the stacking efficiency of the flood-control dike is improved, and more emergency rescue time is gained for the flood-control project.
