Description

Technical Field

[0001] This utility model relates to the field of water conservancy dredging technology, specifically to a water conservancy dredging device with a protective structure. Background Technology

[0002] A search revealed that patent CN202123376418.7 discloses a water dredging and unblocking device. While this device works by inserting a rotating roller into a water pipe, starting a drill, and driving the roller to rotate, which in turn drives a threaded brush to clean the silt from the inner wall of the pipe; simultaneously, water flows through the inlet into various through-holes, impacting the eccentric paddle and causing it to rotate. This rotation, via a first universal joint, drives a support rod, which, constrained by a second universal joint, causes a showerhead located outside the rotating roller to rotate synchronously with the eccentric paddle. Water enters the support rod through the inlet and then through the outlet into the showerhead, spraying out onto the inner wall of the water pipe to dilute the silt, the showerhead only dilutes the silt during use. Furthermore, silt may enter these through-holes with the water flow, causing blockages. Furthermore, once silt enters the through-hole, it can not only cause blockages but also increase the rotational resistance of the eccentric impeller and support rod, making the shower head rotate unevenly or stop rotating altogether. This further limits the shower head's dilution range and effectiveness, and may also increase wear and tear and the failure rate of the device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a water conservancy dredging device with a protective structure, which solves the problems mentioned in the background art.

[0004] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0005] A water conservancy dredging device with a protective structure includes a rotating rod, an auger on the rotating rod, and a pointed cone at the front end of the rotating rod;

[0006] The rotating rod consists of a connecting rod and a connecting section. The pointed cone and the connecting section are provided with inclined surfaces. A high-pressure nozzle is installed on the inclined surfaces of the pointed cone and the connecting section. A main pipe is opened inside the connecting rod and the connecting section. A branch pipe is opened on the pointed cone and the connecting section. The high-pressure nozzle is connected to the main pipe through the branch pipe.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the auger is connected to the rotating rod via a connecting section, and a gap is left between the auger and the connecting rod to facilitate the discharge of sludge flushed by the high-pressure nozzle through the gap.

[0009] The beneficial effects of adopting the above-mentioned further solutions are:

[0010] The gap between the auger and the connecting rod provides a smooth discharge channel for the sludge. As the auger rotates and loosens the sludge, the water jet from the high-pressure nozzle can more easily penetrate the sludge layer, refining it and accelerating its discharge. This design reduces sludge buildup around the equipment, thereby improving sludge discharge efficiency. The gap effectively prevents sludge from clogging between the auger and the rotating rod. If sludge is tightly compressed between the auger and the rotating rod, it may cause the equipment to malfunction or even stop. The gap design allows sludge and water to pass smoothly as the auger rotates, reducing the risk of clogging. The gap between the auger and the connecting rod also reduces direct friction and wear from the sludge on the equipment. If sludge comes into close contact with and rubs against the auger and the rotating rod, it may cause rapid wear on these components. The gap design allows sludge to have less direct contact with the equipment during flow, thus extending the equipment's service life.

[0011] Furthermore, the connecting rods and connecting sections are distributed in a crisscross pattern, and the diameter of the connecting rods is smaller than the diameter of the connecting sections, which facilitates the flow of sludge at the rotating rods.

[0012] The beneficial effects of adopting the above-mentioned further solutions are:

[0013] The cross-distribution design of the connecting rods and joints provides a smoother path for sludge to flow through the rotating rod. This design reduces the risk of sludge accumulation and blockage inside the equipment, allowing it to pass through and be discharged more smoothly. Because the diameter of the connecting rod is smaller than that of the joint, this difference makes it easier for the sludge to be pushed and discharged at the rotating rod. The smaller connecting rod diameter reduces resistance when sludge passes through, thus improving dredging efficiency. Simultaneously, the cross-distribution of the connecting rods and joints also increases the equipment's agitation and loosening effect on the sludge, further enhancing the dredging effect. The cross-distribution design allows the connecting rods and joints to distribute pressure when subjected to sludge impact and abrasion, reducing the stress on any single component. This design helps extend the equipment's service life and reduces the risk of equipment damage due to sludge impact.

[0014] Furthermore, the auger is driven to rotate by a rotating rod to discharge sludge from the pipe.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] Driven by a rotating rod, the auger generates a powerful thrust within the pipe, effectively discharging sludge from it. This design ensures rapid sludge removal and improves dredging efficiency. The auger's rotation helps prevent sludge buildup and blockage inside the pipe. By continuously agitating and agitating the sludge, the auger ensures unobstructed flow within the pipe, thereby enhancing the equipment's reliability and stability.

[0017] Furthermore, two augers are provided on the outer side of the rotating rod, and the two augers are evenly distributed on the rotating rod.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] Two augers, evenly distributed on the rotating rod, can simultaneously act on the silt within the pipe, accelerating its loosening and removal. This design significantly improves the efficiency of dredging operations and shortens the dredging cycle. The rotational motion of the augers not only moves the silt but also creates a strong agitation effect inside the pipe. The even distribution of the two augers ensures more uniform agitation, helping to disperse solid particles in the silt and reducing the risk of blockage. In practical applications, water pipes may vary in shape and size. The even distribution of the two augers allows the equipment to better adapt to complex and changing pipe environments, ensuring consistent and stable dredging results. The even distribution of the two augers on the rotating rod helps balance the force, reducing the risk of equipment damage caused by excessive force on a single auger. This design improves the durability and reliability of the equipment, extending its service life.

[0020] Furthermore, the slope of the inclined plane is 45 degrees, which facilitates the high-pressure nozzles on the inclined plane to assist in increasing the discharge efficiency of the sludge loosened by the screw conveyor.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] The 45-degree slope allows the high-pressure nozzles to spray water at a more optimal angle. This angle ensures sufficient impact force to loosen and refine the sludge while preventing direct impact on other parts of the equipment, thus avoiding unnecessary wear or damage. The sloped nozzles more evenly cover the sludge-loosened area by the auger. As the auger rotates, the sludge is continuously agitated and loosened, while the high-pressure nozzles effectively flush it out of the pipes. This synergistic effect significantly improves sludge removal efficiency. The sloped design helps reduce sludge buildup around the equipment. Once the sludge is loosened by the auger, the high-pressure nozzles quickly flush it away, preventing blockages. The sloped design reduces direct impact and wear from the sludge. Compared to water sprayed directly onto a flat surface, the water flow on the slope is more dispersed and has less impact on the equipment, thus extending its lifespan.

[0023] This utility model provides a hydraulic dredging device with a protective structure. It has the following beneficial effects:

[0024] The equipment effectively loosens and removes sludge from pipes through an auger structure on a rotating rod. The auger's design gradually pushes the sludge towards the pipe outlet during rotation, thus improving dredging efficiency.

[0025] The rotating rod consists of connecting rods and connecting sections arranged in a crisscross pattern, with the diameter of the connecting rods being smaller than the diameter of the connecting sections. This design not only enhances the strength of the rotating rod but also facilitates the flow of sludge through it, reducing the risk of sludge accumulation and blockage inside the equipment.

[0026] A gap is left between the auger and the connecting rod to facilitate the discharge of sludge flushed by the high-pressure nozzles. Simultaneously, the beveled design of the cone and connecting section, along with the high-pressure nozzles mounted on the beveled surfaces, helps increase the efficiency of discharging sludge loosened by the auger. This combination of high-pressure flushing and mechanical loosening further enhances the dredging effect.

[0027] The connecting rod and connecting section have a main pipe, while the cone and connecting section have branch pipes. The high-pressure nozzles are connected to the main pipe through the branch pipes. This structural design allows high-pressure water to be smoothly delivered to each high-pressure nozzle, ensuring consistent flushing results. Meanwhile, the slope of the inclined plane is designed at 45 degrees, which facilitates the discharge of sludge and ensures the stability and durability of the equipment. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A hydraulic dredging device with a protective structure includes a rotating rod 3, on which two augers 2 are mounted. These two augers 2 are evenly distributed on the outer side of the rotating rod 3, allowing them to simultaneously act on the silt within the pipe, significantly accelerating the loosening and discharge of the silt and shortening the dredging cycle. The rotational motion of the augers 2 not only moves the silt but also creates a strong stirring effect inside the pipe. The even distribution of the two augers 2 ensures more uniform stirring, helping to disperse solid particles in the silt and reducing the risk of blockage. Furthermore, this design allows the device to better adapt to complex and changing pipe environments, ensuring consistent and stable dredging results. Simultaneously, the even distribution of the two augers 2 helps balance the force, reducing the risk of equipment damage caused by excessive force on a single auger 2, improving the durability and reliability of the equipment. The augers 2, driven by the rotating rod 3, rotate and discharge the silt from the pipe. Driven by the rotating rod 3, the augers 2 generate a strong pushing force inside the pipe, effectively discharging the silt. This design ensures rapid removal of sludge and significantly improves dredging efficiency. The rotation of the auger 2 not only helps prevent sludge from accumulating and clogging inside the pipe, but also ensures unobstructed flow by continuously stirring and pushing the sludge, thereby improving the reliability and stability of the equipment. The front end of the rotating rod 3 is equipped with a pointed cone 1.

[0040] Example 2

[0041] To increase dredging efficiency, for example, such as Figures 1 to 4As shown, the invention also includes: the rotating rod 3 is composed of a connecting rod 301 and a connecting section 304, which are intersected. The diameter of the connecting rod 301 is smaller than the diameter of the connecting section 304, facilitating the flow of sludge at the rotating rod 3. This intersecting design provides a smoother path for the sludge to flow at the rotating rod 3. This layout reduces the risk of sludge accumulation and blockage inside the equipment, ensuring smooth sludge discharge. The difference in diameter between the connecting rod 301 and the connecting section 304 makes it easier for sludge to be pushed and discharged at the rotating rod 3, reducing the resistance to sludge passage and improving dredging efficiency. Furthermore, the intersecting connecting rod 301 and connecting section 304 enhance the mixing and loosening effect of the equipment on the sludge, further improving dredging performance. Meanwhile, this design helps to disperse the pressure of sludge impact and wear on individual components, extending the service life of the equipment. The auger 2 is connected to the rotating rod 3 via a connecting section 304, and a gap is left between the auger 2 and the connecting rod 301, allowing the sludge flushed by the high-pressure nozzle 4 to be discharged through this gap. This pre-reserved gap between the auger 2 and the connecting rod 301 forms a highly efficient sludge discharge channel. During the auger 2's rotation to loosen the sludge, the water jet from the high-pressure nozzle 4 easily penetrates the sludge layer, refining it and accelerating its discharge. This design significantly reduces sludge accumulation around the equipment, thereby improving sludge discharge efficiency. The gap effectively prevents sludge blockage between the auger 2 and the rotating rod 3, avoiding the risk of equipment malfunction or downtime due to tightly packed sludge. Meanwhile, the gap design reduces direct contact between sludge and equipment, lowering friction and wear, and extending equipment lifespan. The cone 1 and connecting section 304 are equipped with inclined surfaces 302 at a 45-degree angle. This allows the high-pressure nozzles 4 on the inclined surfaces 302 to assist in increasing the discharge efficiency of sludge loosened by the auger 2. The 45-degree angle of the inclined surfaces 302 allows the high-pressure nozzles 4 to spray water at a more optimal angle. This angle ensures sufficient impact force to loosen and refine the sludge while preventing direct impact on other parts of the equipment, thus avoiding unnecessary wear or damage. The high-pressure nozzles 4 on the inclined surfaces 302 can more evenly cover the area of ​​sludge loosened by the auger 2, working in synergy with the rotational motion of the auger 2 to significantly improve sludge discharge efficiency. Furthermore, the design of the inclined surfaces 302 helps reduce sludge accumulation around the equipment, avoiding the risk of sludge blockage.Meanwhile, the slope design of the inclined surface 302 reduces the direct impact and wear of sludge on the equipment. Compared with water flow directly sprayed on a flat surface, the water flow on the inclined surface 302 is more dispersed and has less impact on the equipment, thereby extending the service life of the equipment. High-pressure nozzles 4 are installed on the inclined surface 302 of the cone 1 and the connecting section 304. The high-pressure nozzles 4 prevent sludge from clogging the auger 2 of the rotating rod 3, thereby preventing the auger 2 from deforming due to the resistance of sludge, thus achieving a protective effect. The connecting rod 301 and the connecting section 304 have a main pipe 305, and the cone 1 and the connecting section 304 have a branch pipe 303. The high-pressure nozzles 4 are connected to the main pipe 305 through the branch pipe 303.

[0042] Working principle:

[0043] Once the equipment is started, the rotating rod 3 begins to rotate, causing the auger 2 mounted on it to rotate as well. The auger 2 is designed to penetrate deep into the pipe, effectively loosening and agitating the sludge inside through the rotation of its spiral blades. The two augers 2 are evenly distributed on the rotating rod 3, ensuring uniform loosening and discharge of the sludge within the pipe, thus improving dredging efficiency.

[0044] While the auger 2 loosens the silt, the high-pressure nozzle 4 begins to operate. The high-pressure nozzle 4 is connected to the main pipe 305 via a branch pipe 303, receiving high-pressure water from the outside. The high-pressure water jet from the nozzle 4 directly impacts the silt loosened by the auger 2, further refining it and accelerating its discharge from the pipe. A gap is left between the auger 2 and the connecting rod 301, allowing the silt flushed by the high-pressure nozzle 4 to drain smoothly through the gap, preventing silt accumulation and blockage at the rotating rod 3.

[0045] The front end of the rotating rod 3 is equipped with a pointed cone 1, the shape of which helps the equipment penetrate the sludge layer as it advances in the pipe, reducing resistance. The connecting section 304 and the pointed cone 1 are equipped with an inclined surface 302, with an inclination of 45 degrees. This design not only facilitates the discharge of sludge but also allows the high-pressure nozzle 4 to spray water more effectively, increasing the loosening and discharge efficiency of the sludge. The high-pressure nozzle 4 on the inclined surface 302, through its high-pressure water jet, further prevents sludge from clogging the auger 2 at the rotating rod 3, thereby reducing the risk of deformation of the auger 2 due to sludge resistance.
