Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a filter screen dredging device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. Water conservancy projects can effectively impound and regulate floods, reduce peak flow, lower the threat of floods to downstream areas, and reduce casualties and property losses caused by floods. Through the construction of reservoirs, water diversion projects, and other infrastructure, water resources are rationally allocated in time and space, transferring water resources from water-rich areas to water-scarce areas, and storing water from seasons of abundance to seasons of scarcity, thereby improving water resource utilization efficiency and ensuring the water supply needs of urban and rural areas as well as industrial and agricultural production.

[0003] Silt in waterways not only affects water quality but also hinders navigation and causes a series of problems. Traditional dredging methods mostly use mechanical excavation or suction, which, while effective, are inefficient and environmentally damaging. In particular, during the silt removal process, incomplete separation of silt from water can easily occur, affecting the dredging effect.

[0004] The existing patent document with authorization announcement number CN221721764U discloses a filter screen dredging device for water conservancy projects, including a filter cylinder with filter holes evenly distributed on its outer side and a connecting pipe inserted into the top of the filter cylinder. In this technical solution, the impact of water flow on the fan blades drives the entire drive assembly to rotate, and the rotation of the drive assembly causes the counterweight head and filter cylinder to rotate synchronously. However, the drive assembly is driven by the impact force of water flow on the fan blades, and the rotation speed at which the counterweight head and filter cylinder rotate synchronously under this action is relatively low, affecting the cleaning effect on the filter cylinder. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a filter screen dredging device for hydraulic engineering. This device solves the problem that the drive assembly, driven by the impact force of water flow on the fan blades, results in a low rotational speed that affects the cleaning effect on the filter cylinder, impacting the synchronous rotation of the counterweight head and filter cylinder. During the dredging process, the fan blades, driven by the water flow, rotate the drive shaft, which in turn rotates the cleaning brush inside the filter screen cylinder. The brush continuously brushes the inner wall of the filter screen cylinder, removing the silt adhering to the filter screen holes, preventing blockage, and ensuring the stability and continuity of the filtration effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water conservancy engineering filter screen dredging device, comprising an installation component, a drive component, and a filter screen component. The installation component includes an installation pipe, a connecting rod, and a counterweight. The drive component includes a positioning outer plate, a drive shaft, and fan blades. The filter screen component includes a filter screen cylinder. A flange is connected to the outer wall of one end of the installation pipe, and a first ring plate is connected to the outer wall of the end of the installation pipe away from the flange. Connecting columns are welded at equal intervals to the inner wall of the positioning outer plate, and a positioning inner plate is connected to the end of the connecting column away from the positioning outer plate. A stabilizing rod is connected to the symmetrical outer wall of the drive shaft, and a cleaning brush is connected to the end of the stabilizing rod away from the drive shaft. A fan blade is connected to one end of the drive shaft, and a plug ring is connected to one end of the filter screen cylinder.

[0007] The beneficial effects of this utility model are as follows: the counterweight is placed in the silt of the river channel. Driven by the water pump, the mud-water mixture at the bottom of the river enters the interior of the filter cylinder through the filter screen holes. As the mud-water mixture flows through the filter cylinder to the installation pipe, the fan blades rotate under the impact of the water flow, which in turn drives the drive shaft and the cleaning brush to rotate.

[0008] To achieve the assembly of the installation tube and the filter cylinder:

[0009] As a further improvement to the above technical solution: a plug groove is provided on the inner side of the end of the mounting pipe away from the flange, and a sealing ring is provided on the inner wall of the plug groove.

[0010] The beneficial effects of this improvement are as follows: the first ring plate and the third ring plate are attached together, and the side of the plug ring connected to the filter screen cylinder is inserted into the plug groove. Then, the first ring plate and the adjacent third ring plate are connected with bolts to realize the assembly of the installation pipe and the filter screen cylinder. The flange is used to connect to the water pump.

[0011] To achieve the assembly of the installation tube, filter cylinder, and counterweight:

[0012] As a further improvement to the above technical solution: one end of the counterweight is connected to a second ring plate, and the end of the drive shaft away from the fan blade is rotatably connected to the wall of the second ring plate away from the counterweight through a bearing.

[0013] The beneficial effects of this improvement are as follows: the second ring plate and the third ring plate are attached together, the third ring plate and the second ring plate are connected with bolts, and then the second ring plate and the first ring plate are connected with connecting rods, thereby realizing the assembly of the installation pipe, filter screen cylinder and counterweight.

[0014] To enhance the stability of the device in the riverbed silt by using counterweights, thus ensuring the effectiveness and safety of the dredging process:

[0015] As a further improvement to the above technical solution: the positioning outer plate is installed on the inner wall of the mounting tube, and the drive shaft is rotatably connected to the positioning inner plate through a bearing.

[0016] The beneficial effects of this improvement are as follows: by setting up a drive shaft, the connected stabilizing rod is rotated when it rotates, thereby realizing the rotation of the cleaning brush. The counterweight enhances the stability of the device in the riverbed silt, ensuring the effectiveness and safety of the dredging process.

[0017] To facilitate the cleaning brush in cleaning the inner wall of the mounting tube and prevent impurities from adhering to the inner wall of the mounting tube:

[0018] As a further improvement to the above technical solution: one end of the drive shaft passes through the positioning inner plate through a bearing and is connected to the fan blade, and the bristles of the cleaning brush on the side away from the stabilizing rod are in contact with the inner wall of the mounting tube and the inner wall of the filter cylinder.

[0019] The beneficial effects of this improvement are: the drive shaft rotates under the drive of the fan blades, which in turn drives the cleaning brush to clean the inner wall of the mounting tube, thus preventing impurities from adhering to the inner wall of the mounting tube.

[0020] In order for the fan blades to rotate and drive the drive shaft and cleaning brush to rotate:

[0021] As a further improvement to the above technical solution: the drive shaft is located inside both the mounting tube and the filter cylinder, and the inner diameter of the mounting tube is the same as the inner diameter of the filter cylinder.

[0022] The beneficial effects of this improvement are as follows: the counterweight is placed in the silt of the river channel, and under the drive of the water pump, the mud-water mixture at the bottom of the river enters the interior of the filter cylinder through the filter screen holes. As the mud-water mixture flows through the filter cylinder to the installation pipe, the fan blades rotate under the impact of the water flow, which in turn drives the drive shaft and the cleaning brush to rotate.

[0023] To allow water to pass through the filter mesh and enter the filter cylinder, while trapping impurities such as silt on the outside:

[0024] As a further improvement to the above technical solution: the outer diameter of the filter cylinder is the same as the outer diameter of the mounting tube, and the circumferential wall of the filter cylinder is uniformly perforated with filter holes.

[0025] The beneficial effects of this improvement are as follows: the filter screen holes evenly distributed on the filter screen cylinder are used to utilize the suction force of the water pump to allow water to enter the filter screen cylinder through the filter screen holes, while impurities such as silt are intercepted on the outside of the filter screen cylinder, thereby achieving the initial separation of silt and water.

[0026] To remove the silt adhering to the area around the filter mesh and prevent it from becoming clogged:

[0027] As a further improvement to the above technical solution: the outer walls of both ends of the filter cylinder are connected to a third ring plate, and the inner side of the third ring plate is provided with grooves with internal threads at equal intervals, and the size of the insertion ring matches the size of the insertion groove.

[0028] The beneficial effects of this improvement are as follows: During the dredging process, the fan blades drive the drive shaft to rotate under the action of water flow, which in turn drives the inside of the cleaning brush filter screen cylinder to rotate. The brushes continuously brush the inner wall of the filter screen cylinder, cleaning away the silt attached to the filter screen holes, preventing the filter screen holes from being blocked, and ensuring the stability and continuity of the filtration effect.
