Description
Technical Field
[0001] This application relates to water conservancy engineering machinery, and in particular to a river dredging device for water conservancy engineering. Background Technology
[0002] River dredging is currently a crucial part of water conservancy projects. With the acceleration of urbanization and the increasing demands for environmental protection, the problems of low efficiency and high cost of traditional manual dredging have become increasingly prominent. Currently, there are various mechanized dredging equipment on the market, such as dredgers and sand pumps. However, these devices generally suffer from poor adaptability, high energy consumption, and secondary pollution. In recent years, domestic and foreign research institutions have begun to explore efficient and environmentally friendly dredging technologies, such as sludge suction devices combined with filtration systems and solar-powered dredging equipment. However, in practical applications, there are still technical bottlenecks such as insufficient dredging depth and poor mud-water separation.
[0003] Existing solutions include dredgers: which use robotic arms to grab silt and are suitable for large-area dredging, but the equipment is bulky, lacks flexibility, and is prone to disturbing the water body and causing secondary pollution; sand pumps: which use negative pressure to extract silt and are highly efficient, but consume a lot of energy and cannot effectively separate mud and water; chain bucket dredging machines: which use chains to drive buckets for continuous operation and can dredge to a greater depth, but have a complex structure and high maintenance costs; and rotary conveyor dredging devices: which use spiral blades to transport silt and are suitable for viscous silt, but have poor adaptability to hard debris.
[0004] Regarding the aforementioned technologies, existing dredging equipment generally suffers from problems such as high energy consumption, poor mud-water separation effect, and insufficient adaptability. In particular, it is inefficient when dredging narrow rivers or complex terrains, and it is difficult to avoid secondary pollution. Summary of the Invention
[0005] The purpose of this application is to provide a river dredging device for water conservancy projects to solve the problems mentioned above.

[0008] Preferably, the outer surface of the suction pipe is fitted with an installation block, and the outer side of the installation block is fixedly connected to the bottom of the installation plate.
[0009] Preferably, the suction pipe is made of high-strength wear-resistant rubber, the suction head is made of stainless steel, and the centrifugal separator is a model with adjustable speed.
[0010] Preferably, the separation mechanism includes a water outlet pipe, the right side of which is fixedly connected to a centrifugal separator, and a sieve frame is installed on the left side of the water outlet pipe, with a screen mesh fixedly connected inside the sieve frame.

[0013] Secondly, the river dredging device for water conservancy projects provided in this application adopts the following technical solution: the energy storage mechanism includes a battery, the bottom of the battery is installed on the top of the centrifugal separator, a fixed frame is fixedly connected to the top of the battery, and a solar panel is installed inside the fixed frame.
[0014] Preferably, the auxiliary mechanism includes a support plate, the left side of which is fixedly connected to the right side of the mounting plate, a flocculant tank is fixedly connected to the top of the support plate, an input pipe is fixedly connected to the left side of the flocculant tank, and the input pipe is fixedly connected to a centrifugal separator.
[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. The mounting plate serves as the supporting foundation for the entire dredging mechanism, providing an installation platform for each component and ensuring overall structural stability. The centrifugal separator is the core component, used to separate the sucked-in sludge. The pipeline connects and transports the sludge. The suction pipe is responsible for sucking in the sludge from the river channel. The auger head agitates the silt on the riverbed and sucks it into the suction pipe through rotation. Multiple auger heads can expand the dredging range and improve dredging efficiency. The cleaning plate can further scrape away the silt on the riverbed when the auger head rotates, enhancing the dredging effect. The mounting block fixes and supports the suction head. The mud suction pipe serves to prevent the suction pipe from shaking during operation, ensuring the stability of the dredging work. The high-strength, wear-resistant rubber material of the suction pipe can withstand the wear of mud and sand in the river channel, extending its service life. The stainless steel auger head has good corrosion resistance and strength, ensuring normal operation in complex environments. The adjustable speed centrifugal separator can adjust the speed according to different mud concentrations and separation requirements to achieve the best separation effect. Through the modular design of the dredging mechanism, the core components are separated from the suction pipe, which can adapt to different terrains and dredging needs. 2. The water outlet pipe is used to discharge the water separated by the centrifugal separator. The screen frame and screen screen perform secondary filtration on the discharged water to further remove any small impurities that may remain in the water, ensuring the quality of the discharged water. The mud outlet pipe transports the mud separated by the centrifugal separator to the mud storage tank. The mud storage tank is used to store the separated mud. The sealing plate seals the mud storage tank when the mud does not need to be cleaned to prevent mud leakage. The handle makes it easy for operators to open and close the sealing plate. The bottom plate provides support for the fixing strip. The fixing strip is inserted into the limiting groove of the limiting block to fix the sealing plate and prevent the sealing plate from opening accidentally during operation. When the mud needs to be cleaned, the fixing strip can be pulled out from the limiting groove to open the sealing plate. Through the dual separation of the centrifugal separator and the filter screen of the separation mechanism, the mud-water separation effect is significantly improved, and the sludge can be stored conveniently and the interior can be cleaned more easily. 3. The storage battery is used to store electrical energy and provide power support for the entire dredging device. When there is sunlight, the solar panel converts solar energy into electrical energy and stores it in the storage battery, achieving energy self-sufficiency, reducing dependence on external power sources, and improving the device's endurance. The support plate provides support for the flocculant tank, which is used to store flocculant. The input pipe transports the flocculant in the flocculant tank to the centrifuge. The flocculant can cause the fine particles in the sludge to agglomerate into larger particles, which are easier for the centrifuge to separate, improving separation efficiency and quality. Energy consumption is reduced through the energy storage mechanism and auxiliary mechanisms, and power can be supplemented by solar energy, reducing operating costs and further improving separation efficiency.
