Embodiment Construction

[0010] Provide best embodiment below in conjunction with accompanying drawing:

[0011] Cyclone silting device 1 is formed and welded by 3mm thick steel plate, the cone angle of the upper cone surface is 90°, the cone angle of the side cone surface is 110°, the thickness of the two-way curved surface is 3mm, and it is formed by hot pressing of the mold to ensure The water flow is smooth and the swirl is efficient. The central flow part is a diverging conical tube (as shown in Figure 1), the ratio of its two ends to the diameter is 0.6, and the guide connecting part 2 is equipped with a movable pipe joint to ensure that the water flow does not flow. When interrupted, the cyclone silting device 1 keeps the vertical direction at any time. The height of the deflector of the spiral flow tube 4 is 1 / 2 of the radius, and its diversion segregation angle is 15°. After hot pressing, the deflector is firmly connected to the pipe wall by welding. The buoyancy of the buoyancy bucket 5 is ...

Abstract

A spiral flow dredging equipment, belonging to the field of hydraulic machinery, is a device that utilizes the natural power of the spiral flow to dredge and discharge silt. The silt scouring device consists of a silt scouring device (1) and a guide connecting part (2 ), a rotating tube (3), the bottom of the cyclone silting device (1) is a smooth two-way curved surface, the side is a conical surface, and the upper end surface is a positive conical surface; The spiral flow pipe (4), the floating bucket (5) and the universal pipe joint (6) for suspending the spiral flow pipe (4) are composed, and it has been very successful after many trials, not only solving the worldwide problem that people have been eager to solve for many years , and has high economic and social benefits.

Description

technical field [0001] The spiral flow dredging equipment of the present invention belongs to the field of hydraulic machinery, and relates to the technical category of hydraulics, hydraulic machinery, and dredging devices. Specifically, it is a device that uses the natural power of the spiral flow to perform automatic dredging and desilting without additional energy. Technical solutions. technical background [0002] At present, the existing dredging projects use natural water flow for desilting, such as: gravity flow, emptying and desilting; or mechanical dredging, that is, dredgers. The former does not require additional energy and mechanical equipment, but consumes a lot of water and has low efficiency; the latter requires high investment and transportation costs, and sediment cannot be transported over long distances. Now rivers, lakes, rivers, seas, and especially reservoirs have very serious siltation phenomenon, which has become a major problem in the world. The tot...
