An automatic floating and sinking water energy pneumatic dredging device

technical field

The utility model belongs to the field of sludge cleaning, in particular to an automatic floating and sinking type water energy pneumatic dredging device.

Background technique

In order to promote the sustained, rapid and stable growth of the national economy, the State Council put forward the development strategy of "relying on the golden waterway and building the Yangtze River Economic Belt", which has brought great opportunities for the development of my country's inland shipping industry. With the development of inland waterway shipping and the increase of ship size, the requirements for channel size are also increasing. Although the construction of the Three Gorges Project has greatly improved the level of the channel and created conditions for large-scale ships, there will still be insufficient water depth in some sections of the backwater area during the ebb and flow period, making it impossible for ships to pass normally. This is mainly because the water storage of the reservoir has changed the natural balance conditions formed by the interaction of water flow, sediment and riverbed in the upper reaches of the Yangtze River for a long time. Accumulative deposition of sediment is caused, and the erosion-silt balance can only be restored after the reservoir has been in operation for a long time. In the river section of the changing backwater area, there will still be a dual state of natural river and reservoir every year. Due to the cumulative deposition of sediment, the riverbed will be raised, and some river sections will have channel water depth and navigation width that cannot meet the normal conditions of ships during the ebb and flow period. Obstructing navigation due to traffic requirements. The main measures to solve the impact of sedimentation on waterways include the following three: one is to optimize reservoir operation, the other is to carry out sediment control through engineering measures, and the third is to take maintenance dredging measures for waterways. However, the first method of reservoir regulation involves a wide range of areas, and a reasonable reservoir regulation plan still needs to face many problems; the second method of the Three Gorges Reservoir has a short operating time, and the engineering measures adopted still need to continue to conduct river channel observation and in-depth analysis and research; The three methods are mainly realized by dredgers, but the cost of each operation and the impact on the ecological environment are great. In response to these problems, Luo Zhaosen and others have recently developed a new method of flushing and transporting sand, the "pneumatic dredging method": it is fixed at a certain river section, and the turbulence of the water flow is enhanced by sending a large amount of gas from the outside to the river, so as to achieve clearing. Silt effect, but the manufacturing process of this method has high operation and management costs, and there are disadvantages of immovability.

In the middle and upper reaches of the Yangtze River, due to the construction of many hydraulic structures, the siltation of the river channel has become more serious, but at the same time, the silt particle size has been continuously refined. The study found that the particle size of most of the silt in the fluctuating backwater area of the Three Gorges Reservoir is less than 0.1mm. Instead of spending a lot of manpower and material resources to dredge the river channel by dredging sand, it is better to reduce the starting flow velocity of the silt at the bottom of the river bed, so that the sediment can move from the shallower water depth to the deeper water depth area at a lower water flow speed, which can It can achieve the purpose of local dredging, and can dynamically adjust the river bed to increase the effective river width in low water period, so as to achieve the effect of improving the waterway.

It can be seen from the knowledge of hydraulics that the flow velocity of the water flow is roughly exponentially distributed along the vertical line. The surface flow velocity is large and the bottom flow velocity is small. Therefore, the river bed sediment can be raised to a certain height by using a certain flow velocity gas. When the flow velocity is greater than the sediment start velocity , the sediment can be transported from the shoal to the downstream deep groove.

To reduce energy loss, the kinetic energy of the water flow can be used to power the entire device. Through the impact of water flow, the propeller is driven to rotate, and through a series of transmission devices, the sliding rod of the inflatable cylinder is driven to work. Combined with the working principle of the inflator, the air is compressed and stored in a rubber airbag similar to a car tire to provide the required gas for pneumatic sand blowing. At the same time, a stainless steel shell is used to wrap the internal structure, water collectors are installed on both sides of the shell, and an exhaust pipe is arranged below. The inlet and outlet valves are installed on the water collector, and the air pressure gauge is installed in the air bag. By injecting water and draining water into the water collectors on both sides, the self-weight of the whole device can be changed to realize its sinking and rising.
