Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Embodiment one
Referring to Fig.1-2, a kind of hydraulic engineering underground piping cleaning plant, including discoid mounting plate 1,1 side of mounting plate
Fixing sleeve is connected to ring-shaped gasbag 2 on wall, air inlet pipe is connected on ring-shaped gasbag 2, and air inlet pipe is connected to the rear of mounting plate 1,
Pressure valve 3 is installed, the middle part of mounting plate 1, which is run through, is equipped with the installing pipe 4 that both ends penetrate through, and installing pipe 4 and peace in air inlet pipe
Loading board 1 is fixedly connected, and the installed in front of installing pipe 4 has a block clearing mechanism, and block clearing mechanism includes scraping ring 7, the inside of scraping ring 7 be equipped with
The fixed plate 8 of its concentric is fixedly connected with multiple connecting rods 9 between scraping ring 7 and fixed plate 8, multiple connecting rods 9 are along fixed plate 8
Circumferential equidistantly distributed is connected with support rod 10 in the middle part of 8 trailing flank of fixed plate, and the other end of support rod 10 extends in installing pipe 4
And it is fixedly connected with sliding plug, and sliding plug and support rod 10 are integrally formed, setting limitation sliding plug abjection at the front end nozzle of installing pipe 4
Annular protrusion, the inside of installing pipe 4 are equipped with level pressure conduction mechanism, and level pressure conduction mechanism includes being fixedly connected on inside installing pipe 4
Magnet ring 11, and magnet ring 11 is located at the rear side of sliding plug, and magnet ring 11 is equipped with magnet attracting therewith close to the side of sliding plug
Block 12, and the contact surface of magnet block 12 and magnet ring 11 seals, installing pipe 4 is between block clearing mechanism and level pressure conduction mechanism
Run through on side wall and be equipped with exhaust outlet 5, gas vent 6, and exhaust outlet 5, close to the front side of installing pipe 4, gas vent 6 is close to installing pipe 4
Rear side.
In the present invention, rubber pad 13 is fixedly connected on the leading flank of magnet block 12, so that magnet block 12 is hitting sliding plug
It is easier to be adsorbed on again on magnet ring 11 by the effect of magnetic force when springing back afterwards.Installing pipe 4 is pvc pipe, will not be to magnet ring 11
It is impacted with the interaction of magnet block 12.
In the present invention, which is placed in water pipeline, ring-shaped gasbag 2 can be bonded realization sealing, Xiang An with tube wall
Gas is continually fed into the rear tube of loading board 1, when magnet block 12 and magnet ring 11 are by together with magnetic-adsorption at this time, it can be achieved that
The intraductal atmospheric pressure of sealing to installing pipe 4,1 rear side of mounting plate increases, and then pushes the device is mobile in water pipeline to advance,
And water pipeline inner wall is carried out by the scraping ring of front side 7 to clear up the dirt struck off on tube wall, stop to be somebody's turn to do when encountering tough stains
When device continues Forward, the rear side air pressure of installing pipe 4 persistently increases, and gas enters ring-shaped gasbag 2 by pressure valve 3, makes
It is sufficiently expanded fits closely with water pipeline inner wall, when the air pressure of 4 rear side of installing pipe is greater than the limit of magnetic-adsorption power
Value, can be such that magnetic force block 12 separates with magnet ring 11, and be moved simultaneously by high pressure gas promotion magnetic force block 12 on front side of installing pipe 4
Support rod 10 is hit, drives the Forward of scraping ring 7 to strike off the dirt on water conservancy inside pipe wall by hitting, and then realize stupid to water conservancy inside pipe wall
Gu the cleaning of dirt.
And after magnet block 12 and support rod 10 are hit, high pressure gas is discharged from exhaust outlet 5, and the air pressure of 1 rear side of mounting plate reduces,
Air pressure also decreases in ring-shaped gasbag 2, and 1 backside gas of mounting plate can push mounting plate 1 to move forward, before pushing scraping ring 7 to continue
It moves, due to the elasticity of rubber pad 13, is sprung back after so that magnet block 12 is hit support rod 10, and the air pressure of 11 rear side of magnet ring at this time
It reduces, magnet block 12 is easier to be adsorbed on again on magnet ring 11 by the effect of magnetic force in rebound, carries out to installing pipe 4 close
Envelope, completes a cleaning operation, if dirt is not still removed, the air pressure of 11 rear side of magnet ring is gradually increased again, similarly leads to
Cross cleaning of the multiple impact realization to water conservancy tube wall dirt.
Embodiment two
Referring to Fig. 3-4, embodiment two and embodiment one the difference is that, the present embodiment connecting rod 9 is inclined to set
Flabellum shape, and more connecting rods 9 cooperate fixed plate 8 to constitute fan impeller structure, are fixedly connected with gas blow pipe 14 on exhaust outlet 5, and
Gas blow pipe 14 is obliquely installed and towards connecting rod 9, is circumferentially equidistantly fixedly connected with multiple scraping blades along it on the front side wall of scraping ring 7
15。
Push magnetic force block 12 to when moving and hit support rod 10 on front side of installing pipe 4 in high pressure gas, high pressure gas is from air blowing
14 water conservancy diversion of pipe blows on flabellum shape connecting rod 9, so make scraping ring 5 generation circumferentially rotate, by the scraping blade 15 on scraping ring 5 to dirt into
Row rotation is struck off, and cleaning soils are more preferable.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
