Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, specifically a dredging device. Background Technology

[0002] Silt is a type of soft soil with a natural water content greater than its flow limit and a porosity greater than 1.5. It is a modern sediment formed in slow-flowing environments such as bays, lakes, or river bends under conditions involving microbial activity. Rich in organic matter, it is often grayish-black in color, has low mechanical strength, and high compressibility. The presence of silt in foundations can easily cause building subsidence. In recent years, water pollution in lakes and rivers has led to severe accumulation of pollutants in bottom sediments. Under certain conditions, these pollutants are released back into the water, causing environmental problems such as cyanobacterial blooms and black, foul-smelling water. River and lake remediation projects have become an important part of environmental governance in recent years. Depending on the type of river, dredging vessels are selected, silt is pumped out, or the silt deposited on the riverbed is stirred into a turbid water state and carried away by the river current.

[0003] Traditional river channels are often accompanied by a large number of aquatic plants, reeds, and aquatic grasses with well-developed root systems. Traditional dredging methods use large suction heads that cannot penetrate deep into the silt. Therefore, it is necessary to be able to reach into the aquatic plants to extract the silt without changing the suction power. Utility Model Content

[0028] In related technologies, riverbanks are often accompanied by a large number of aquatic plants, reeds, and aquatic grasses with well-developed root systems. Traditional dredging methods use large suction heads that cannot penetrate deep into the silt, resulting in significant resistance.

[0029] In order to solve the problems in the related technologies to a certain extent, this application provides a dredging device. When needed, multiple suction tubes 13 are branched off from the main pipe 11, thereby reducing the volume of the suction head 14 and reducing the resistance to insertion.

[0030] This application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figures 1-3This application provides a dredging device, including a dredging component 1. The dredging component 1 includes: a main pipe 11 with a diversion pipe 12 at its bottom; a suction pipe 13 at the bottom of the diversion pipe 12; a suction head 14 at the bottom of the suction pipe 13; and a connecting pipe 15 connecting the top of the main pipe 11 and a pump body. A support component 2 is provided on the dredging component 1. The support component 2 includes: a support plate 21 on the outer wall of the main pipe 11; a fixing rod 24 connected to the support plate 21; the diameter of the suction pipe 13 being smaller than the diameter of the main pipe 11; a ring 27 sleeved on the suction pipe 14 and having a blade inside; a connecting rod 271 connected to the ring 27; and a magnetic block 28 on the outer wall of the connecting rod 271.

[0032] When in use, first connect the main pipe 11 to the branch pipe 12 by thread. Then, install the suction head 14 onto the suction pipe 13 to form a fork shape and insert it into the bottom of the root system of the aquatic plants. Then, connect the connecting pipe 15, which is connected to the pump body, to the top of the main pipe 11 to suction the silt at the bottom. The diameter of the suction pipe 13 is smaller than that of the main pipe 11, and multiple suction pipes 13 are set up, which can reduce the size of the suction head 14, but increase the number, and the amount of silt extracted will not change. When one suction head 14 is blocked, the other suction heads 14 can continue to work. When the main pipe 11 is working on the shore, it can be connected and fixed by the fixing rod 24 fixed on the shore to increase stability. When aquatic plants are wrapped around the suction pipe 13, the ring body 27 is moved up and down to cut the aquatic plants with the blade. When not in use, it is attached to the branch pipe 12 by magnetic block 28.

[0033] In some embodiments, a filter screen 16 is provided at the bottom of the suction head 14, and a cone head 17 is provided at the bottom of the suction head 14. The filter screen 16 is to prevent large stones from entering the suction head 14, and the cone head 17 is to facilitate the insertion of the suction head 14 into the silt, and to repeatedly pull it out and insert it according to the suction situation, thereby reducing the inhalation of aquatic plants.

[0034] In some embodiments, a handle 18 is provided on the outer side wall of the main tube 11. The handle 18 is for the convenience of inserting and removing the main tube 11.

[0035] In some embodiments, the support plate 21 has a semi-circular structure. The semi-circular support plate 21 encloses the main pipe 11, which facilitates installation, and the main pipe 11 can be moved repeatedly on the support plate 21.

[0036] In some embodiments, the outer wall of the support plate 21 is provided with a universal ball 22, and the top of the fixing rod 24 is provided with a ball groove 23 that cooperates with the universal ball 22. The universal ball 22 is fixedly connected to the ball groove 23, so that the support plate 21 can drive the main pipe 11 to adjust its angle through the universal ball 22, thereby better supporting the main pipe 11.

[0037] Specifically, the rotation principle of the universal ball 22 and the ball groove 23 can be referred to the DN50 model ball rotary joint.

[0038] In some embodiments, the ball groove 23 and the fixed rod 24 are rotatably connected by a connecting block 25, and the ball groove 23 is threadedly connected to the connecting block 25. The threaded connection between the ball groove 23 and the connecting block 25 at the top of the fixed rod 24 further increases the rotation angle of the support plate 21.

[0039] In some embodiments, a support rod 26 is provided at the bottom of the fixing rod 24. The support rod 26 is inserted into the ground to assist in supporting the fixing rod 24.
