Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water intake equipment, in particular to a large water intake equipment based on a coal unloading barge. Background Technique
[0002] When building a large water intake project on the banks of rivers, lakes and reservoirs, the water level has a large drop between the dry season and the wet season, and the water level rises and falls relatively quickly. Since the bank slope is relatively flat and the water depth is relatively small, while the middle section has a steep slope and a large water depth, a trestle can be built on the lower and flat bank slope, and the bridge extends to the deep water area. A rocker arm type water intake pump ship is used to draw water in the deep water area. When building a large water intake facility on the banks of rivers, lakes and reservoirs where the bank slope is steep and the water depth meets the water intake requirements, piers can be directly built at the shore end, and a rocker arm type water intake pump ship is used to draw water. Therefore, the water intake equipment is one of the essential equipment in the water intake project. Among them, an independent barge is combined with the water intake equipment to realize water intake, which is widely used in large water intake projects of projects such as power, water conservancy, chemical industry, and waterworks.
[0003] The existing water intake equipment is combined with an independent barge for water intake. Although the cost is lower than that of a civil engineering pump house, the overall cost is still not cheap. An independent water intake barge with a water intake of 3000m3 / h has a high investment cost. The independent barge occupies the shoreline resources. The independent barge needs to be far away from other docks and water structures. Generally, it needs to occupy about 200 meters of the shoreline. The hull of the independent barge is small, and the anti-wind safety system is relatively low.
[0004] Therefore, the technical personnel in the field provide a large water intake equipment based on a coal unloading barge to solve the problems proposed in the above background technique. Content of the Utility Model
[0005] The purpose of the utility model is to provide a large water intake equipment based on a coal unloading barge to solve the problems of high cost and poor wind resistance and insufficient stability of the existing water intake equipment when used in combination with an independent barge proposed in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A large water intake device based on a coal unloading barge, comprising: a water intake pump set, the bottom of the water intake pump set is connected with a main water delivery pipe, and a steel approach bridge for traction is arranged outside the main water delivery pipe. A first expansion joint is installed at the lower end of the main water delivery pipe, and a first spherical joint is connected to the lower end of the first expansion joint. A second water delivery pipe is connected to the lower end of the first spherical joint, and a second expansion joint is installed at the lower end of the second water delivery pipe. A third water delivery pipe is connected to the lower end of the second expansion joint. A second spherical joint is installed at the lower end of the third water delivery pipe, and a third expansion joint is installed at the lower end of the second spherical joint. A fourth water delivery pipe is connected to the lower end of the third expansion joint. A third spherical joint is installed at the lower end of the fourth water delivery pipe, and a tail water delivery pipe is connected to the lower end of the third spherical joint.
[0008] As a further scheme of the present utility model: The main water delivery pipe is interconnected with the second water delivery pipe through the first expansion joint and the first spherical joint, and the second water delivery pipe is interconnected with the third water delivery pipe through the second expansion joint.
[0009] As a further scheme of the present utility model: The third water delivery pipe is interconnected with the fourth water delivery pipe through the second spherical joint and the third expansion joint, and the fourth water delivery pipe is interconnected with the tail water delivery pipe through the third spherical joint.
[0010] As a further scheme of the present utility model: The inner wall of the upper end of the expansion joint is provided with internal threads.
[0011] As a further scheme of the present utility model: The outer wall of the end of the first spherical joint is provided with external threads.
[0012] As a further scheme of the present utility model: The expansion joint is connected by the mutual cooperation of the internal threads on the inner wall and the external threads on the first spherical joint. A universal ball head shaft is movably installed in the middle of the first spherical joint.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] 1. Since the barge will have rolling and pitching, and the water level will move up and down over time, resulting in displacement between the barge and the steel approach bridge and between the steel approach bridge and the shore base. In order to avoid the impact of displacement on the water intake system, the setting of the spherical joint and the addition of expansion joints between each section of the water delivery pipe effectively reduce the adverse effects brought by the displacement of the barge, enabling the entire water intake system to operate stably.
[0015] 2. It is used in combination with a coal unloading barge. The coal unloading barge is heavier than an independent barge, and it has better wind resistance and stability as a whole. By adopting the combination of a coal unloading barge and a water intake system, relying on the existing conditions of the coal unloading barge and the steel approach bridge, the water intake system eliminates interference and adverse factors, and combines the coal unloading barge with the water intake system together, which has the advantages of small occupied area, low investment cost, good stability, high safety and strong inclusiveness.
