Abstract

The invention relates to a siphon dredging device which belongs to the environmental protection field. Water conservancy facilities such as built reservoirs, ponds and son on, all can appear the sediment deposition, which causes the lives of the water conservancy facilities to be greatly shortened. A few years ago, the country only focuses on the development of the economy and neglects the environmental protection, which causes that the water pollution is serious, and the contamination along with the sediment is hidden at the water bottom to become a long pollution source. To solve the problem, the invention smartly takes advantage of a gasbag, a hose and the siphon principle to suck the silt out. The invention chooses pipes with the engineering plastic as the material (the specific gravity is one-sixths of that of the steel), so the maximum feature of the invention is light, flexible and convenient. Firstly, the invention has flexible installation and conveyance, can be disassembled to other places for installation and reuse after the invention is used at one place; secondly, the invention has flexible use, the water surface pipe uses the hose with a joint function and the gasbag and the underwater silt suction pipe also uses a ring-shaped gasbag, so the moving velocity is slow but flexible; thirdly, the invention is flexible in silt suction and silt discharge, the reason is that the pipes on both ends can be lengthened according to the need. So the invention is practical in dredging and decontamination at the water bottom.

Description

Siphon dredging device

Technical field

The invention belongs to field of environment protection.

Background technology

After the founding of New, the Chairman Mao has sent the indication of " water conservancy is the lifeblood of agricultural ", and all parts of the country have started the climax of construction of reservoir small reservoirs decades.As time goes on, water-bed desilting mud is thickeied year by year, and therefore individual other water conservancy projects is scrapped, and this phenomenon is at the water conservancy projects especially severe of the Huanghe valley.When at present China was quickening process of industrialization and exploitation tourism resource, some pollutants sank under water, as long as hot weather or external force vibrations, will the dregs of society gain an upper hand, permanent polluted source.Make that precarious water environment makes the matter worse originally; Owing in the early stage of reform and opening-up, disorderly dig disorderly everywhere and adopt indiscriminate felling of trees.Ignored the protection to environment, water and soil desertifies and runs off seriously, thereby has accelerated the process of scrapping of many water conservancy projectss.Also there is invention to want to solve this difficult problem, eventually because of using inconvenience to be difficult to carry out.The present invention aims at can convenient, flexible desilting design.

Summary of the invention

Purpose of the present invention: being provides a kind of simple, flexible, energy-conservation Accrete clearing device for reservoir, the pool, the water-bed desilting mud in weir (or the water off coast has the lower lake of physical features, pond etc.).To be the potential energy that utilizes high water level be drawn onto the pipeline sewage draining exit place of low water stage with the desilting mud at the bottom by siphon piping for it, thereby reach the purpose of desilting scrubbing.This prolongs the life-span in some power station and sets up the society of benign cycle economy and sustainable development cleaning water pollution source and water-bed desilting mud, and positive meaning is arranged.

Technical scheme of the present invention: some need must be used tube material and equipment with the identical engineering plastics pipe of specification size (iron pipe also can) and other, form siphon piping, place river course water surface drop greater than about 5 meters the dykes and dams by the mode of Fig. 1.When connecing various pipeline equipment, plastic washer must use in the joint, definitely can not have the slit to leak gas, shut the gate valve at two ends after, make the pipeline between the gate valve of two ends can become airtight space.Pipe between water filling port 3 and gate valve 1 and the gate valve 2 can extend as required.The quantity of trustship air bag 12 is as the criterion in face waterborne can hold up the pipeline that fills with mud.Air bag 12 can be used fat, oil drum, the Plastic Drum of hard.The joint number of flexible pipe 4 can be lacked usefulness when the water surface is wide, can use when the water surface is narrow more, and is so that pipeline is when the water surface moves, flexible as the joint.The quantity of the annulus air bag 5 of silt-sucking tube under water, the depth of water when submarine pipeline is long, be used more; Pipeline is usefulness less in short-term, can move degree of being flexibly with the following mud-sucking device of the water surface.Annulus air bag 5 can utilize the discarded inner tube of a tyre of automobile.Inhale become silted up mouthful gate valve and watch window 2, use the transparent material manufacturing, whether blot only so that the mud of position is inhaled by observation post.Water filling port 3 is extreme higher positions of whole pipe, but it must be lower than the theoretical level of siphon as far as possible.Inhale the thick slag window 8 of filter (square, rectangle all can) of mud mouth, preferably lattice is made of iron, so that play the effect of some tumblers, the little square lattice length of side should be less than pipe diameter, the grid iron bar is provided with slightly to overhanging iron nail, hang some film of fabric etc. so that block, and also will be convenient to unloading and remove slag.Rotate 180 degree about chassis 11 energy of elevator 9 flexibly.Arm 10 can move up and down the angle about 90 degree, so that increase the suction mud area that each scanning is moved.

1 is a siphon piping row silt mouthful gate valve among the figure.The 2nd, siphon piping silt-sucking tube gate valve and watch window.The 3rd, water filling port.The 4th, flexible pipe.The 5th, the annulus air bag.The 6th, trumpet type is inhaled the mud mouth.7 give birth to the thick slag window of the filter card of inhaling the mud mouth at trumpet type, and the 8th, inhale the mud mouth and filter thick slag window (having special figure to represent).The 9th, small-sized elevator device.The 10th, the elevator arm.11 elevator chassis.The 12nd, the trustship air bag.

The specific embodiment

At first measuring needs the bosom in the desilting waters degree of depth, as connecting the standard of silt-sucking tube road length under water, also is simultaneously in order to inhale when becoming silted up with this, and trumpet type is prepared at the bottom of inhaling the few leaving water of mud mouth.Mode by Fig. 1 installs various pipe fittings and equipment.Start elevator, trumpet type is inhaled the mud mouth be put into the bottom.Shut the gate valve 1 and 2 at syphon two ends, screw off the big nut of water filling port, with small-sized water pumper in pipeline, pour water, exhaust, till filling.Screw the big nut of water filling port, open gate valve 1 and 2 simultaneously.Just can see muddy black mudflow process is arranged in the pipeline of watch window.If examine when not having muddy black mud stream in the pipeline of window, need judge that then trumpet type inhales the mud mouth and be less than the bottom, or other reasons, so that take appropriate measures.The suction silt time is long, inhaling the mud mouth filters on the pane of thick slag window, be certain to block things such as some fabric plastic sheetings of extension, trumpet type can be inhaled the mud mouth during eliminating and improve suitably height, single suction is water for a moment, when mouthful no silt is become silted up in the row for the treatment of, shuts (all operations of closing two gate valves simultaneously in the work of two gate valves more simultaneously, to stay silt less in the pipeline as far as possible), start elevator and trumpet type is inhaled the mud mouth mention the replacing that thick slag window is filtered on the ship limit.Afterwards, trumpet type is inhaled the mud mouth be put back into the bottom, open two gate valves simultaneously, repeat the work of front.If the original place can be drawn back with the water of heap silt place clarification in the place of water resource preciousness.(aquatic work personnel must wear life vest during work, and note life safety at any time).
