DETAILED DESCRIPTION
[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0024] like Figure 1 , Figure 2 As shown, a sand pumping ship comprises a hull 1, a working platform 2 is horizontally arranged inside the hull 1, and the working platform 2 is divided into a sand storage area 21 and a sand pumping area 22 located on the left and right sides. The sand storage area 21 is used to hold sand, and the sand pumping area 22 is provided with a sand stirring tank 3, a mixing conveyor 4, a conveyor belt 5, a water sand pump 6 and a sand pumping pipe 7.
[0025] like Figure 1 , Figure 2 As shown, the sand stirring pool 3 is sunken and arranged in the sand pumping area 22, and the mixing conveyor 4 is arranged in the sand stirring pool 3. The conveyor belt 5 connects the sand storage area 21 and one end of the sand stirring pool 3, the water sand pump 6 is connected to the other end of the sand stirring pool 3, and the sand pumping pipe 7 is connected to the outlet end of the water sand pump 6.
[0026] When it is necessary to assist the cofferdam construction, the dry sand is stored in the sand storage area 21, and the hull 1 is used to transport the dry sand to the location of the filling construction, and then the sand pumping pipe 7 is laid out, so that one end of the sand pumping pipe 7 is connected to the water sand pump 6, and the other end extends to the working location.
[0027] Then, the dry sand is transferred to the sand stirring pool 3 by the conveyor belt 5, and water is poured into the sand stirring pool 3. The sand is stirred by the mixing conveyor 4, so that the formed water sand is transferred to the position of the water sand pump 6. Finally, the water sand pump 6 is used to input the water sand into the sand pump pipe 7 to realize the blowing and filling construction at the designated position.
[0028] Therefore, by using a single ship to pump sand over long distances, the terrain can be ignored and construction efficiency can be effectively improved. The sand pumping ship is easy to manufacture, has a short production time, low use cost, and high construction efficiency. It avoids various problems such as serious pollution, high noise, and the construction of steel trestle platforms caused by earth-rock cofferdams and steel sheet pile cofferdams, ensures construction under conditions of large tidal ranges on the water and short operating time, and improves operating efficiency.
[0029] like Figure 2 As shown, the mixing conveyor 4 includes a rotating shaft 41, a spiral blade 42, a water spray pipe 43 and a water pump 44. The rotating shaft 41 is horizontally rotatably arranged in the sand stirring tank 3, and the spiral blade 42 is arranged on the outer wall of the rotating shaft 41. The water spray pipe 43 is horizontally arranged above the sand stirring tank 3, and a plurality of nozzles 45 are evenly distributed at the lower end. The water pump 44 is connected to the water spray pipe 43.
[0030] When the sand is stirred and transported, the rotating shaft 41 drives the spiral blade 42 to rotate synchronously to transport the dry sand. During the transportation process, the water pump 44 sucks the seawater and injects it into the water spray pipe 43, so that the seawater is sprayed out along the nozzle 45. During the transportation process of the dry sand, the dry sand and water are automatically stirred and mixed, thereby improving the production efficiency of water sand.
[0031] like Figure 3 , Figure 4 As shown, the sand pumping pipe 7 includes multiple sections of pipes 71 and multiple connectors 72. The outer wall of the connector 72 is provided with a buoy 73, so that the sand pumping pipe 7 can float on the water surface when in use, preventing the sand pumping pipe 7 from sinking into the water, thereby ensuring the stable transportation of water and sand and ensuring the work efficiency during the cofferdam construction.
[0032] like Figure 3 , Figure 4 As shown, both ends of the connector 72 are provided with insert tubes 74 for inserting into the pipe 71, both ends of the connector 72 are rotatably connected with mounting plates 75, both ends of the pipe 71 are provided with connecting plates 76 that abut against the mounting plates 75, and a locking piece 8 is provided between the mounting plates 75 and the connecting plates 76.
[0033] like Figure 3 , Figure 4 As shown, the locking member 8 includes a locking block 81, a locking rod 82, a pull ring 83 and a spring 84. The locking block 81 is arranged in a dovetail shape and is fixed to the inner side wall of the mounting plate 75. The inner wall of the connecting plate 76 is provided with a groove 85 for the locking block 81 to be embedded and a dovetail groove 86 connecting the groove 85 and for the locking block 81 to be slidably embedded.
[0034] like Figure 3 , Figure 4 As shown, the locking rod 82 passes through the mounting plate 75 and the locking block 81, a locking hole 87 for the locking rod 82 to be inserted is provided in the dovetail groove 86, a pull ring 83 is provided at the end of the locking rod 82, and a spring 84 is sleeved on the outer wall of the locking rod 82 and is used to control the locking rod 82 to be inserted into the locking hole 87.
[0035] When assembling the sand pump pipe 7, the insert pipes 74 at both ends of the connector 72 are inserted into the ends of the pipe 71, and then the pull ring 83 is pulled to drive the locking rod 82 to move outward and disengage from the locking hole 87, and then the mounting plate 75 is rotated so that the locking blocks 81 on the mounting plate 75 are embedded in the grooves 85 on the connecting plates 76 at both ends of the pipe 71, and then the mounting plate 75 is rotated so that the locking blocks 81 slide into the dovetail grooves 86, so as to realize the limit fixation of the connector 72 and the pipe 71 in the axial direction.
[0036] Then, the pull ring 83 is loosened, and under the pulling force of the spring 84, the locking rod 82 is inserted into the locking hole 87 to achieve the circumferential limit fixation of the connector 72 and the pipe 71, thereby realizing the rapid assembly of the sand pumping pipe 7. The disassembly process of the sand pumping pipe 7 is the opposite, which will not be described in detail.
[0037] Therefore, by providing a segmented sand pumping pipe 7, it is possible to select a suitable number of pipes 71 and connectors 72 according to the use requirements, and then assemble the sand pumping pipe 7 to adapt to different use distance requirements. At the same time, it can also be stored in segments to reduce the occupied space.
[0038] In addition, during the arrangement of the sand pumping pipe 7, since a buoy 73 is provided on each connector 72, the sand pumping pipe 7 can float on the water surface when in use, preventing the sand pumping pipe 7 from sinking into the water, thereby ensuring the stable transportation of water and sand and ensuring the working efficiency during the cofferdam construction.
[0039] like Figure 1 As shown, a circle of skirting boards 23 are vertically arranged around the working platform 2 to prevent wastewater on the working platform 2 from overflowing into the seawater and reduce pollution to the seawater environment. Anti-skid steel plates 24 are laid on the surface of the working platform 2 to ensure that workers can work stably and prevent slipping. Steel pipe guardrails 25 are arranged around the working platform 2 to improve safety during work.

After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
