Abstract
The invention relates to a dredging sucker, comprising an inner pipe and an outer pipe; the outer pipe is sheathed and fixed outside the inner pipe, a helix pilot ring which is sheathed on the outsidewall of the inner pipe is arranged in the tube gap of the outer pipe and the inner pipe and a plurality of draining openings are arranged on the lower end of the pipe wall of the inner pipe; the lowe r opening of the outer pipe is connected with at least two brace rods, the other ends of the brace rods are connected with the circumference of a stating ring symmetrically and a support pillar is positioned at the axle center of the stating ring. When the dredging sucker works, water body which suffers internal suction passes thought the helix pilot ring between the outer pipe and the inner pipe to form a helix cone-shaped stream, rushes down from the draining openings and can break ground and suck mud, thus preventing the sucker from being blocked; the bottom part of the sucker is cone-shaped, which can facilitate ground breaking, accelerate underwater excavation and improve the efficiency of dredging and desilting supporting pillar under the action of the supporting pillar. The invention features simple structure and high service efficiency, thus being applicable to various occasions.
Description
Technical field
The present invention relates to a kind of dredging sucker, be applicable to the hydraulic engineering such as dredging, desilting, underwater excavation of various occasions.
Background technology
Existing dredging sucker technology all has very high requirement to the energy, cost, structure.The patent No. is 85107771 swirling flow mud absorbing head, and disclosed soil-suction head apparatus structure is loaded down with trivial details, installation, maintenance inconvenience, technological requirement height, cost height; A kind of suction channel that is used to dredge of disclosed a kind of twin flue two imports of patent No. CN02825794.4, its weak point is: space pump up water efficient is not high between outer tube and interior pipe; The pipe mouth of pipe in the outer tube mouth of pipe is lower than is inhaled the mud import and is easily stopped up the interior pipe mouth of pipe, and the import that causes absorbing water was lost efficacy, and structure design is unreasonable, poor practicability.
Summary of the invention
The objective of the invention is in order to overcome the structure that exists in the prior art loaded down with trivial details, complicated operation, use cost height, the suction nozzle mouth of pipe easily stops up, shortcomings such as poor practicability, and provide a kind of simple in structure, be convenient to operation, high efficiency, and be difficult for a kind of dredging sucker of plugging.
In order to achieve the above object, the technical solution used in the present invention is: a kind of dredging sucker, comprise interior pipe, outer tube, interior pipe is gone up the socket outer tube, its technical characterstic is to be provided with the helical water guide ring that is placed on the outer wall of inner tube between the tube gap of described outer tube and interior pipe, has a plurality of drainage openings on the tube wall of interior pipe lower end; Described outer tube lower nozzle connects at least two brace rods, and the other end symmetry of at least two brace rods is connected on the retainer ring circumference, and described retainer ring axle center is provided with a fore-set.Water body is subjected to pipe suction in the suction nozzle, current are entered under the generation of the helical water guide ring between inner and outer pipe helicon current by outer tube upper orifice and interior ligament and dash, impact interior silt of managing in the lower nozzle by drainage opening 7, the suction nozzle mouth of pipe can not stopped up, improved the operating efficiency of suction nozzle, and simple and compact for structure, installation and maintenance are convenient, need not additional source of energy, use cost is low.
On the pipe, pipe upper orifice in the upper orifice of outer tube is lower than, the lower nozzle of outer tube are lower than the suitable for reading of interior pipe lower end drainage opening and are higher than the lower nozzle of interior pipe described outer tube in " L " type seat is fixed in more than two groups; Described retainer ring and interior pipe concentric, and the retainer ring diameter is less than diameter of inner pipe; Described fore-set and retainer ring concentric, fore-set is fixed in the retainer ring axle center and fore-set stretches out outside the retainer ring through support.Brace rod is supported in the silt, makes whole suction head apparatus more firm, and many brace rods prevent the suction of bulk silt stone as the suction nozzle otch, and the protection suction nozzle normally uses; Fore-set can break silt, improves the suction nozzle operating efficiency.
The present invention forms the current that downward spiral impacts by the helical water guide ring between inner and outer pipe and both can break ground, and manages lower nozzle simultaneously in the drainage open impact of interior pipe lower nozzle again, prevents that the mouth of pipe from stopping up, need not additional source of energy, economize on resources, and reduce use cost; Tapered by the suction nozzle bottom that many brace rods are formed, simultaneously through the fore-set effect, can conveniently break ground, accelerate underwater excavation speed, improve dredging, desilting efficiency data.This sucker structure is simple, low cost of manufacture, and installation and maintenance are convenient, and are practical.
Description of drawings
Fig. 1 is a perspective view of the present invention.
Among the figure: interior pipe 1, outer tube 2, helical water guide ring 3, brace rod 4, retainer ring 5, fore-set 6, drainage opening 7, " L " type seat 8,81, support 9.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
A kind of dredging sucker shown in Fig. 1, pipe 1, outer tube 2, helical water guide ring 3 in comprising, interior pipe 1 external series gap is with an outer tube 2, interior pipe 1 outer wall circumferencial direction is provided with many " L " type seats 8, outer tube 2 outer walls be provided with above " L " type seat of 81, two groups of many " L " type seats of corresponding outer wall of inner tube " L " type seat 88,81 corresponding connect make in pipe 1 fixedly connected with outer tube 2; In socket one helical water guide ring 3 on the outer wall of inner tube in pipe 1 and the tube gap of outer tube 2 or on the outer tube wall in the tube gap of interior pipe 1 and outer tube 2, pipe 1 upper orifice in outer tube 2 upper orifices are lower than, interior pipe 1 lower end is provided with many drainage openings 7, and outer tube 2 lower nozzles are lower than the suitable for reading of drainage opening 7 and are higher than interior pipe 1 lower nozzle; Many brace rods 4 of outer tube 2 lower nozzle outer walls welding, the other end of many brace rods is fixed in a retainer ring 5 peripheries, because retainer ring and interior pipe concentric and diameter less than diameter of inner pipe, make many brace rod integral body that are connected and fixed ring be conical, be convenient to suction nozzle and insert in the silt; Connect a fore-set 6 through support 9 in the retainer ring 5, fore-set and retainer ring concentric and fore-set stretch out outside the retainer ring, further make things convenient for suction nozzle to break silt, improve the suction nozzle operating efficiency.
During this suction nozzle underwater operation, fore-set 6 breaks silt, retainer ring 5, many brace rods 4 support suction nozzle, water body is subjected to the inner suction of suction nozzle, water body is entered under the 3 generation helicon current of the helical water guide ring between inner and outer pipe by outer tube 2 upper orifices and interior pipe 1 gap and dashes, impact interior silt of managing in 1 lower nozzle by drainage opening 7, pipe 1 mouth of pipe can not stop up in making, and has improved the operating efficiency of suction nozzle.
