HYDRODYNAMIC REACTION-FREE TOOL FOR
SURFACE CLEANING
The invention relates to the technology of hydrodynamic cleaning of surfaces and may be used for development of tools for cleaning above-water and underwater surfaces of various structures. The tool has a body having a grip with working fluid supply pipeline passages. The body is connected to a tool barrel. A high-pressure working nozzle is connected to the barrel. The tool has a protective strap on the grip and an adapter. A hose connects the working fluid supply pipeline passages with a high-pressure source through said adapter. A working fluid flow rate regulator with an adjusting knob is mounted on the body and is connected to the working fluid supply pipeline. The free end of the barrel is ended with a tailpiece to form an ejector and a high-pressure chamber behind the barrel exit section at the side of location of the working nozzle relative to the barrel. The working nozzle is fixed to the barrel tailpiece. A head- piece with adjusting ports is arranged on the barrel tailpiece. A support clamp is mounted on the regulator of the ejector. The ejector is formed by axial-symmetric through passages made in the tailpiece and arranged around the barrel exit section. The regulator of the ejector is made in the form of an adjusting ring capable of rotating about the headpiece of the barrel and having openings communicating with the adjusting ports of a headpiece. The barrel axis of the tool may be rectilinear or curvilinear.
The effect from realization of the invention wo 01/10577 2 consists in a simple design, enhanced reliability and high efficiency of the work to be performed with its help. The tool provides safety for the operator and enhances the functional possibilities of the tool during operation.
The invention relates to technological devices for hydrodynamic cleaning of surfaces and can be used for design and production of tools, for example, for cleaning ship's hulls and submersible structures, hydraulic engineering structures and any other surfaces from biofouling, corrosion, polluting spots and other skin stratification when performing the land and underwater work.
Known in the prior engineering art is a reaction-free underwater tool for hydrodynamic cleaning of ship's hulls from biofouling. The tool has a body with a grip, a barrel carrying a high-pressure jet generator, a hose to supply working fluid from a high-pressure source through the body to the barrel of the tool and a counter-nozzle for a reaction jet opposite to the straight jet of the working nozzle; the counter-nozzle is formed by a profiled streamlined shroud fitted with a propeller provided with a tail piece and set in rotation by means of a hydraulic motor (cf. RF patent No. 2107006 MnK6 B 63 B 59/08, 1996) The achievement of a required technical result in the known tool is hindered, for example, by its complexity, bulkiness and multiple-element design, that makes its operation inconvenient for the operator and reduces the reliability of such a tool.
Besides, the operator working with this tool should __ _..._ __.. _. _. _._ ___-_. _-_ __ _._ _ I ' WO 01/10577 3 be continuously in the working zone and under a constant effect of the cocurrent jet from the operation of the counter-nozzle that reduces the efficiency and productivity of the work.
The most relevant technical solution taken as a prototype is a hydrodynamic reaction-free surface cleaning tool comprising a body with working fluid supply pipeline passages, a barrel connected to the body, an ejector secured on the barrel, a protective strap, an adapter connected to the housing body, a high-pressure working nozzle connected to the barrel, an ejector mounted on the barrel, an adapter secured on the housing body, and a hose connected to the working fluid supply pipeline passages to feed the working fluid through the body adapter from a high-pressure source (cf. US patent 4,716,849, IPC B 63 B
59/00 (NKI 114/222), 1988).
The achievement of a required technical result in the prior art is impeded by the complex design of the tool, its bulk arrangement due to disposition of the ejector compensating the counter jet at the end of the barrel opposite to the jet nozzle of the high pressure generator, as well as many elements of the I
tool and technological complexity of manufacturing I
~i~ the compensating ejector with preset parameters. The necessity of tapping off the cocurrent jet from the compensating ejector behind the operator's back to exclude its effect on the operator himself reduces the efficiency and productivity of the work and creates certain inconveniences when handling such a tool.
The basic object of the invention is to create a hydrodynamic reaction-free tool for cleaning surfaces wo 01/10577 4 providing economy in use, ecological safety increasing the productivity of the operator's work and allowing him to carry out the job under water and on land.
The technical results obtained due to the achievement of this object and realization of the claimed invention include simplification of the design, an enhanced reliability of the tool, an increased safety for the operator working with this tool, an increase of the quality and efficiency of the operations, as well expansion of the range of surfaces to be treated with the help of the given tool.
This object is attained and the technical result is achieved by providing a hydrodynamic reaction-free tool for cleaning surfaces comprising a body with passages of a fluid supply pipeline to feed the working fluid, a barrel connected to the body, a high-pressure working nozzle connected to the barrel, an ejector mounted on the barrel, a protective strap, an adapter secured on the body, and a hose connecting the working fluid supply pipeline passages to transfer the working fluid from a high-pressure source through the adapter; according to the invention the tool is provided with a working fluid flow-rate regulator with an adjusting knob mounted on the body grip and communicating with the working fluid supply pipeline, a tail piece installed on the free end of the barrel to form an ejector and a high pressure chamber behind the barrel exit section at the side of location of the working nozzle relative to the barrel which, in turn, is fixed to the barrel tail piece, a head-piece with adjusting ports mounted w0 01/10577 5 on the barrel tail piece, an ejector regulator carrying a support clamp, the ejector being formed by axial-symmetric through passages made in the tail piece and arranged around the barrel exit section, the ejector regulator being made in the form of an adjusting ring capable of rotating about the head-piece of the barrel and having openings communicating with the head-piece adjusting ports, the barrel axis of the tool being rectilinear or curvilinear.
The tool may be provided with, at least, one adapter connecting the body to the barrel through the working fluid flow-rate regulator.
The barrel tailpiece of the tool may be removable or made as an integral part of the barrel.
The adjusting ports of the headpiece of the tool and the adjusting ring openings overlapping them may be made axially symmetrical relative to the barrel axis.
The nature of the present invention and its aspects will be more readily understood from the following brief description of the accompanying drawings, in which:
Fig. 1 is general view of the tool with local cross sections;
Fig. 2 is the unit 1 of Fig. 1;
Fig. 3 is a nose part of the tool barrel with a support clamp;
Fig. 4 is the tool barrel having a curvilinear axis.
Hydrodynamic reaction-free tool for cleaning surfaces comprises a body 1 with passages 2 of a working fluid supply pipeline. A barrel 3 is connected with the body 1. A high-pressure working wo 01/10577 6 fluid pipeline 4 is connected to the barrel 3.
The tool has a protective strap 5 secured on the I body 1, an adapter 6 installed on the body 1, and a hose 7 connecting the passages 2 of the working fluid supply pipeline of the body 1 through its adapter 6 to a high-pressure source (not shown). A working fluid flow-rate regulator 8 mounted on the body 1 has a control knob 9 and communicates with the working fluid supply pipeline. A tail piece 10 is provided on the free end of the barrel 3 to form an ejector 11 and a high-pressure chamber 12 behind the barrel exit section 3 at the side of the high-pressure working nozzle 4 relative to the barrel 3. The working nozzle 4 is mounted on the tailpiece 10 of the barrels 3. A
head-piece 13 with adjusting ports 14 is mounted on the tailpiece 10 of the barrel 3. A support clamp 16 is installed on the regulator 15 of the ejector 11.
The ejector 11 is formed by axisymmetric through passages 17 made in the tailpiece 10 and arranged around the barrel exit section 3. The regulator 15 of the ejector 11 is made in the form of ratable adjusting ring 18 mounted on the mouth piece 13 of the barrel 3, the ring 18 having openings 19 interacting with the adjusting ports 14 of the mouth piece 13. The axis 20 of the barrel 3 of the tools may be rectilinear or curvilinear.
The tool may have at least one adapter 21 connecting the body 1 with the barrel 3 via the working fluid flow-rate regulator 8.
The tailpiece 10 of the barrel 3 may be made as a removable part or integral with the barrel 3.
The adjusting ports 14 of the headpiece 13 and overlapping opening 15 of the adjusting ring wo 01/10577 7 18 of the regulator 15 of the ejector 11 may be made i, symmetrical relative to the axis of the barrel 3.
The tool operates as follows.
The working fluid under a predetermined pressure passes through the hose 7 from the working fluid supply source 2 (not shown) through the adapter 6 into the passages 2 of the working fluid supply pipeline to the body 1. Then the working fluid is fed to the flow-rate regulator 8, in which the flow rate i is adjusted by turning the control knob 9. The working fluid with a preset flow rate is fed through ;
the barrel 3 into the high pressure chamber 12 of the tail piece 10 and therefrom into the high-pressure i working nozzle 4.
From the high-pressure working nozzle 4 the working fluid is jetted onto the surface being treated (not shown) and clears it from stratification, biofouling, corrosion products, etc.
During the outflow of the working fluid from the jet nozzle 4 a counterthrusting force appears that acts on the operator through the body 1. To compensate for this counterthrusting force, the tailpiece 10 is provided with axisymmetric passages 17 forming with the high-pressure chamber an ejector 11. To control the flow rate of the ejector 11, the tool is provided with a regulator 15 made in the form of an adjusting ring 18 capable of rotating about the tailpiece 10 of the barrel 3 and having openings 19 overlapping the adjusting ports 14 in the mouth piece 13 installed on the tailpiece 10. By turning the ring 18, due to the interaction of the openings 19 and ports 14, the flow rate of the ejector 11 is controlled and its draft is varied according to the pressure in the working fluid supply pipeline and the preset flow rate. To provide a stable position of the high-pressure working nozzle 4 relative to the treated surface (not shown), the tool is provided with a clamp 16 mounted on the regulator 15 of the ejector. To protect the operator's hand, the tool is provided with a protective strap 5 secured on the body 1. The axis 20 of the barrel 3 may be rectilinear (Fig. 1) or curvilinear (Fig. 4} for outlet of the cocurrent jet from the operator's working zone. This improves the operating conditions for the operator and increases the productivity. The curved axis 20 of the barrel 3 may also be used for treatment of geometrically complex surfaces and for treating the surfaces and their elements in hardly accessible places.
Some embodiments of this tool may have an adapter 21, connecting barrel 3 with the body 1 and allowing one to operatively replace the barrels 1 with one having other characteristics of the ejectors 11, headpieces 13, etc.
It should be noted that, in contrast to the prior art, the claimed tool can be used both under water for removing the biofouling from ship's hulls, propellers and submersible structures, and on land for cleaning surfaces and structures from corrosion, paint layers, dirt, atmospheric bedding or anather similar job required for obtaining a clean surface for further treatment (grinding, painting, electroplating, etc.). The claimed design of the tool allows one to do all these jobs.
Thus, the claimed tool is simple and reliable in operation, provides a required safety of the operator, increases the quality and efficiency of the
