Abstract
The utility model discloses an pneumatic scouring and silting device, which comprises a plurality of scouring and silting pipes and a compressor which are arranged underwater, a plurality of air holes are distributed on the scouring and silting pipe, the compressor is connected with the scouring and silting pipe; the scouring and silting pipes are arranged flakily, each scouring and silting pipe is connected in parallel with the compressor; the angle between the center line of the air hole distributed on the scouring and silting pipe and the horizontal plane is -10 to -80 degrees; a valve is arranged between each scouring and silting pipe and the compressor. The utility model has the advantages that the device can promote alluvial sediment incipient motion arising quickly and can take the alluvial sediment away in lower velocity water flow. The utility model has the advantages of better desilting effect, energy saving and wide application prospect in the national water conservancy and water transportation engineering.
Description
One, affiliated technical field
The utility model relates to a kind of Accrete clearing device, is used for channel cleanout under the desilting of hydraulic engineering tide-block sluice gate, the lock, constructs a dam and tear that the dam uses, quickens that reservoir draws sand, alleviates river channel sedimentation, alleviates the navigation channel open, the alluvial of power plant's intake and port and pier, keep water-drawing channel not become silted up or reduces depositing etc.
Two, background technology
River course, Haikou, gate etc. locate that the silt alluvial can have a strong impact on that the river course is unimpeded, ship navigation and prevention waterlogging water drainage.The sand grain of China's river course seashore is thin, and the heavy speed of sedimentation is little, and sediment moving incipient velocity is big, needs bigger water velocity just can make sediment incipient motion, raise up and hold fortune under the arm.Usually use dredge boat or ship to drive drag harrow in China at present and remove channel deposits alluvial under the tide-block sluice, but, back-silt very soon after the desilting owing to there is the marine site next husky.For example Haihe River silting downstream tidal barrier is the most serious, and obstruction is drained off floodwaters, and for this reason, all needs before the annual flood to dredge.In existing dredging method, drive drag harrow etc. as high-pressure water jet method, ship, its efficient is not high, and needs manpower to cooperate, and fund input is bigger.There is surge (F1udization) to dash the method for becoming silted up abroad, draw water to the pipe that has aperture with water pump, utilize current that silt is taken away, this mainly uses on the thick tidal inlet mouth entrance bar navigation channel of particle, but the method is inapplicable on the thin river course of China's silt.
Three, summary of the invention
The purpose of this utility model provide a kind of utilize air-flow to dash to become silted up dash the silt device.
For achieving the above object, the technical solution of the utility model is: a kind of pneumatic towards the silt device, it is characterized in that it comprises to lay underwater become silted up pipe and the compressor of dashing, on the silt pipe, be distributed with air vent, compressor with dash the pipe that becomes silted up and link to each other.
Generally speaking, bigger towards the silt area, and the pipe that dash to become silted up is thinner, therefore, need many to make up towards the silt pipe, make it slabbing, every communicates towards silt Guan Douyu air duct.The mode of pipe combination of dash becoming silted up is a lot, as is arranged in parallel or circular arrangement etc.
When bigger towards the silt area, and the pipe that dash to become silted up is when only being arranged in a slice, and the gas of compressor output just is difficult to the pressure that reaches certain, thereby the efficient of becoming silted up is dashed in influence, simultaneously every to dash the pipe area that becomes silted up too big, just can not carry out piecemeal to the desilting place according to actual needs and control.Therefore, the utility model will be combined into multi-disc towards the silt pipe, and every is connected in parallel on the compressor towards the silt pipe.
Every all is distributed with air vent on the silt pipe, but its aperture will be stopped up by silt if air vent makes progress, if air vent will be blocked by the riverbed downwards.Through repeatedly calculating and testing, air vent should be distributed in the Side below towards the silt pipe, and the angle of its center line and horizontal plane is-10 °～-80 °.
For implementing stator control, every is equipped with valve towards between silt pipe and compressor.
Design principle of the present utility model is: in the river bed or the place of requirement of engineering desilting bury the pipe that dash to become silted up underground, form pipe-line system, link to each other with on the bank air compressor machine towards the silt pipe, compress into air by compressor, air upwards floats by the air vent on the silt pipe and drives silt and raise up, under the drive of certain current, the silt that raises up is taken away.The air compressor machine burst is calmed the anger in turn, and the tracheae resistance is little, can carry more remote.
The utility model has the advantages that: utilize this device can promptly impel the silt starting to raise up, and under flow action, can take away silt than minimum velocity.If when no flood is drained, then do not need to dredge dry year, save the expense of dredging.As long as this device arranges pipe-line system, promptly can control automatically.China's river course coast mud sand grain is thin, and the water conservancy marine traffic engineering often suffers severe siltation, and this device is fit to China's silt characteristics, and dredging effect is good, conserve energy, has broad application prospects in the water conservancy marine traffic engineering.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the cross section structure schematic diagram towards the silt pipe.
Five, the specific embodiment
The pneumatic of the utility model design formed by dashing silt pipe 1 and compressor 2 towards the silt device, make by the PVC material towards the silt pipe under water, waterbornely make by steel pipe or pvc pipe, every towards 10 meters of silt pipe ranges, 0.25 meter of internal diameter, be provided with air vent 3 on the tube wall of silt pipe vertically equably, the diameter of air vent is 2 millimeters, and the distance of adjacent air vent is 0.1 meter.Every becomes a slice towards the silt tube side-by-side, and multi-disc is connected in parallel on the ventilating pipe, ventilation
Pipe links to each other with compressor 2.Every is provided with valve 4 towards the silt pipe.Size of pipe and compressor of dash becoming silted up and model are because of the different variations to some extent towards silt place situation.
