Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering devices, and in particular to a dredging device for water conservancy projects. Background Technology

[0002] In addition to strict water quality monitoring, water conservancy engineering also involves various water treatment processes. These processes are diverse, encompassing biological treatment, sediment removal, and waste disposal. Sediment removal, in particular, typically involves treating silt, sediment, and other impurities. If these sediments are not removed promptly, they can gradually reduce the capacity of rivers, lakes, or reservoirs, thereby affecting the normal functioning of water conservancy facilities and the smooth flow of water.

[0003] To effectively treat sediment buildup, these devices are typically equipped with multiple components such as excavation, suction, and agitation. For example, excavation equipment uses a bucket to scoop up sediment from the bottom of the water body and then transports it to a designated location for further treatment via a complex conveying structure. However, during the lifting process in the water, sediment is prone to overflow, which not only increases the difficulty of treatment but may also cause secondary pollution to the environment. Suction devices require powerful negative pressure equipment to complete the task, but these devices also draw in large amounts of water while pumping out sediment. This not only increases the complexity of subsequent treatment but may also lead to water waste. Therefore, when designing and using these devices, various factors need to be comprehensively considered to ensure the efficiency and environmental friendliness of sediment buildup treatment.

A spiral drive plate 310 is screwed into the inner wall of the main pipe 300. The spiral drive plate 310 has a columnar cavity corresponding to the central axis of the main pipe 300. A feed inlet 320 is provided at the front end of the main pipe 300 along its length. A feed hopper 330 connected to the main pipe 300 is provided on the feed inlet 320. The feed hopper 330 is connected to the feed inlet 320 and its opening direction is tangential to the outer periphery of the main pipe 300. A central fixed shaft 400 is disposed in the columnar cavity and fixed to the base 100, and the diameter of the central fixed shaft 400 matches the diameter of the columnar cavity; An engine 500 is mounted on the base 100 and drives the main pipe 300 to rotate.

[0021] In existing technologies, dredging devices suffer from complex structures and are easily affected by upper-level water during operation.

[0022] The water conservancy engineering dredging device provided by this utility model includes a base 100, a rotating bearing assembly 200, a main pipeline 300, a central fixed shaft 400, and an engine 500.

[0023] The base 100 serves as the structural foundation. It provides the foundation for the installation of subsequent components and also acts as the installation base for the entire hydraulic engineering dredging device. For example, the base 100 can be installed on a ship's hull, allowing the dredging device to perform the dredging process in a suitable location. The hydraulic engineering dredging device can be equipped with a lifting drive, a horizontal rotation drive, or a horizontal transfer drive, thus achieving high adaptability in its working position.

[0024] The rotary bearing assembly 200 is mounted on the outer periphery of the base 100. The rotary bearing assembly 200 may include multiple rotary bearings, thereby providing a foundation for stable support of the subsequent main pipeline 300. The structural form of the rotary bearings is not a key feature; as long as they achieve the desired rotational support effect, it is sufficient. For example, the rotary bearing may include an inner ring and an outer ring that are configured to rotate relative to each other.

[0025] The main pipe 300 is rotatably mounted on the base 100 via a rotating bearing assembly 200. A spiral drive plate 310 is screwed into the inner wall of the main pipe 300. The spiral drive plate 310 has a cylindrical cavity corresponding to the central axis of the main pipe 300. A feed inlet 320 is provided at the front end of the main pipe 300 along its length, and a feed hopper 330 connected to the main pipe 300 is correspondingly provided on the feed inlet 320. The feed hopper 330 is connected to the feed inlet 320, and its opening direction is tangential to the outer periphery of the main pipe 300. When the main pipe 300 rotates, the feed hopper 330 can perform a digging action, and the excavated silt can enter the main pipe 300 through the feed inlet 320. The front end of the main pipe 300 can be closed or open, and there is no specific restriction.

[0026] A central fixed shaft 400 is disposed in the cylindrical cavity and fixed to the base 100. The diameter of the central fixed shaft 400 matches the diameter of the cylindrical cavity. A spiral feeding drive is formed by the cooperation of the spiral drive plate 310 of the main pipe 300 and the central fixed shaft 400. Specifically, the spiral drive plate 310 conveys the sludge entering the main pipe 300 along the outer wall of the central fixed shaft 400.

[0027] The engine 500 is mounted on the base 100 and drives the main pipe 300 to rotate. The type of engine 500 can be various, and is not limited to an electric motor or a combustion engine.

[0028] In summary, the main pipe 300 is rotatably mounted on the base 100 via the rotating bearing assembly 200. A spiral drive plate 310 is screwed into the inner wall of the main pipe 300, and the spiral drive plate 310 has a columnar cavity corresponding to the central axis of the main pipe 300. A feed hopper 330 is provided on the main pipe 300. When the main pipe 300 rotates, the feed hopper 330 can perform a digging action, and the excavated silt can enter the main pipe 300 through the feed inlet 320. The spiral drive plate 310 of the main pipe 300 cooperates with the central fixed shaft 400 to form a spiral feeding drive. Specifically, the spiral drive plate 310 transports the silt entering the main pipe 300 along the outer wall of the central fixed shaft 400. The above-described modified spiral feeding structure realizes the digging action while feeding, thus achieving efficient removal of silt without affecting the upper water body while maintaining a simple structure.

[0029] In one embodiment, the dredging device for water conservancy projects further includes a discharge pipe, one end of which is aligned with the end of the main pipeline 300.

[0030] In this embodiment, the introduction of a discharge pipe allows the sludge extracted by the dredging device in the water conservancy project to be guided to the required location (such as a storage tank). The discharge pipe can be made of various types of polymer materials, thus allowing for flexible adjustment.

[0031] Reference Figures 1 to 4 In one embodiment, the base 100 extends outward and is provided with a fixing ring 110, a fixing strip 120 is connected in the fixing ring 110, the inner diameter of the fixing ring 110 is consistent with the inner diameter of the main pipe 300 and forms a contact joint, the middle fixing shaft 400 is connected to the fixing strip 120, and the discharge pipe is connected to the fixing ring 110.

[0032] In this embodiment, a fixing method for the central fixed shaft 400 is provided, which also provides a basis for fixing the discharge pipe.

[0033] In one embodiment, the height of the feed hopper 330 gradually decreases at its front end in the direction of the length of the main pipe 300.

[0034] In this embodiment, the height direction of the feed hopper 330 is radial to the main pipe 300. The gradual decrease in the height of the feed hopper 330 allows the feed hopper 330 to perform better digging actions during the rotation of the main pipe 300.

[0035] In one embodiment, the feed hopper 330 extends beyond the main pipe 300 in the longitudinal direction.

[0036] In this embodiment, by restricting the structure of the feed hopper 330 so that it extends beyond the main pipe 300, the front end of the feed hopper 330 can perform a more efficient digging action and finally enter the main pipe 300 from the feed inlet 320.

[0037] Reference Figure 1 In one embodiment, the number of feed inlets 320 is multiple and they are evenly distributed around the main pipe 300.

[0038] In this embodiment, the number of feed hoppers 330 is increased, so that multiple feed hoppers 330 can generate more efficient digging action during the rotation of the main pipe 300.

[0039] In one embodiment, the engine 500 and the main pipeline 300 are connected by a belt or chain.

[0040] In this embodiment, by limiting the linkage method, the distance between the engine 500 and the main pipeline 300 can be increased, thus preventing the engine 500 from being affected by harsh working environments.

[0041] In one embodiment, the feed hopper 330 and the feed inlet 320 are connected by welding.

[0042] In this embodiment, the connection between the feed hopper 330 and the main pipe 300 is limited to welding, which has the advantages of simple operation and high structural strength.

[0043] In one embodiment, the dredging device for water conservancy projects includes a slide rail assembly, and the base 100 is slidably mounted on the slide rail assembly and slides along the length of the slide rail assembly.

[0044] In this embodiment, the slide rail assembly can have various structural forms, such as a groove structure, on which a slide block is slidably disposed, and the base 100 is mounted on the slide block, so that the hydraulic engineering dredging device can slide based on the base 100.

[0045] In one embodiment, the main pipe 300 and the feed hopper 330 are made of stainless steel.

[0046] In this embodiment, considering the harsh environment of the main pipeline 300 and the feed hopper 330, stainless steel is used to meet the requirements of strength and weather resistance.

[0047] In summary, the dredging device for water conservancy projects provided by this utility model has a main pipe 300 rotatably mounted on a base 100 via a rotating bearing assembly 200. A spiral drive plate 310 is screwed into the inner wall of the main pipe 300, and the spiral drive plate 310 has a columnar cavity corresponding to the central axis of the main pipe 300. A feed hopper 330 is provided on the main pipe 300. When the main pipe 300 rotates, the feed hopper 330 can perform a digging action, and the excavated silt can enter the main pipe 300 from the feed inlet 320. The spiral drive plate 310 of the main pipe 300 cooperates with the central fixed shaft 400 to form a spiral feeding drive. Specifically, the spiral drive plate 310 transports the silt entering the main pipe 300 along the outer wall of the central fixed shaft 400. The modified spiral feeding structure realizes the digging action while feeding, thus achieving efficient removal of silt without affecting the upper water body while maintaining a simple structure.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
