Definitions

  • the apparatus of the invention comprises a housing, header, stator, rotor appearing as a number of radial pipe-lines, and generators of high-pressure jets.
  • the housing appears as a shaped disk partially filled with a shifting ballast.
  • the stator carries a platform provided with supports.
  • the profiled rotor vanes create a negative pressure beneath the housing of the apparatus.
  • the distances between the injector and the extreme points of the pattern of the contact between the jet and the surface being treated are specified. Provision is also made for a device for changing the direction of motion of the entire cleaning apparatus.
  • Variant II of the apparatus for hydrodynamic cleaning of surfaces is distinguished for the fact that the angle of turn of the axis of the generator nozzles in a horizontal plane with respect to the axis of the radial pipe-lines in the direction of the rotor rotation exceeds zero degrees. Rotation is imparted to the rotor by ejector nozzles, each of which is disposed on the radial pipe-line of the rotor header at the right angles to the axis thereof.
  • a technical result of the practical implementation of the present invention with any variant of embodiment of the proposed apparatus for hydrodynamic surface cleaning consists in higher working reliability of the apparatus, as well as its higher effectiveness, throughput capacity, operating safety, and an extended range of surfaces to be treated, including work on land. Two sheets, 16 dependent claims, 13 drawings.
  • the invention relates to technological apparatus aimed at hydrodynamic cleaning of surfaces and can find application in designing and creating apparatus for cleaning, e.g., ships and submersible structures, waterworks, and any other surfaces from getting fouled with marine growth, corrosion, soiling, and other similar deposits accumulated on the surfaces to be treated both under water and on land.
  • a device for mechanical cleaning ships' hulls from getting fouled with marine microorganisms comprising a disk-shaped housing and a rotatable rotor disposed underneath said disk-shaped housing and receiving rotation from a motor.
  • the rotor appears as a number of radial scrapers producing mechanical action, when the rotor rotates, on foul deposits accumulated on the surface being treated for the surface to get rid of said deposits (cf. US Patent #4,372,242, IPC 3 B 63 B59/00 (NPC 114/222), 1983).
  • hydromechanical device for cleaning underwater surfaces of ships, comprising a housing, hydraulic pump, disk-shaped brushes, and high-pressure nozzles for treating the surface being treated, as well as water-jet propelling nozzles for the device to move in water in various directions.
  • the high-pressure nozzles have an adjustable setting angle
  • the disk-shaped brushes have an adjustable angle of slope (cf. RU Patent #2,098,315, IPC 6 B 63 B 59/08, 1996).
  • one more hydrodynamic device for surface cleaning comprises a housing carrying wheel-shaped supports, a ring header provided with high-pressure nozzles and communicating, via a reducer, with the central portion of the housing, and a hose connected to the source of high pressure which feeds the working fluid to the header.
  • the header rotates by virtue of the reaction force of the jets discharging from the high-pressure nozzles which simultaneously clean the surface being treated (cf. US Patent #5,048,445, IPC 5 B 63 B 59/00 (NPC 114/222, 1991).

  • the apparatus of the present invention operates as follows.
  • the apparatus is put on the surface to be cleaned to assume a preset vertical position being oriented in the direction of its motion, this being due to the provision of the shifting ballast 12 (e.g., water) held in the interior of the housing 1.
  • the shifting ballast 12 e.g., water
  • the apparatus When the supports 7 are magnetic ones and the surface being treated can be magnetized regardless of where the cleaning operations are carried out, i.e., under water or on land, the apparatus is magnetically held to the surface being treated. If the supports 7 are non-magnetic, or the surface being treated cannot be magnetized, at the initial period of time the apparatus is held on the surface by the operator.
  • the working fluid is pressure-fed through the pipe-line 10 and the reducer 9 to the interior of the stator 3 of the header 2. It is due to the provision of the reducer 9 as a swivel pipe connector that it can assume a preset vertical position and remains so oriented during any manipulations with the apparatus. Further on the working fluid enters the rotor 4 along the radial pipe-lines 5 and therefrom passes to the working nozzles of the generators 6 of high-pressure jets.
  • the working fluid While discharging from the generators 6 of high-pressure jets positioned at an angle to the surface 8 being treated, according to Variant I of the invention, the working fluid develops a reaction force which causes the header rotor 4 to rotate.
  • the working fluid is fed not only to the generators 6 of high-pressure jets the axes of the nozzles of said generators being turned in the direction of rotation of the rotor, i.e., in the direction opposite to the direction of rotation of the rotor 4 but also to the ejector nozzles 18positioned at the right angles to the axis of the pipe-line 5.
  • the working fluid While discharging from the nozzles 18 the working fluid creates a reaction force which causes the rotor 4 to rotate.
  • a total force that causes the rotor 4 to rotate is defined by a difference between the forces established by the nozzles 18 and by the nozzles of the generators 6 of high-pressure jets.
  • the shaped vanes 17 disposed on the rotatable rotor 4 establish a flow of the working fluid moving from under the lower shaped surface 11 of the housing 1 and directed from the center to the periphery thereof to create a negative pressure (rarefaction) underneath the lower surface 11 of the housing 1 due to both a discharge of the working fluid and the fact that lower surface 11 of the housing 1 is shaped under a definite law, which provides for creating an extra force which presses the apparatus against the surface 8 being treated.
  • said extra forces press the apparatus against the surface 8 being treated so that once the rotor 4 has started rotating, the operator may no longer keep the apparatus forcedly on the surface 8 being treated.
  • the working fluid shaped into a jet acts upon the foul deposits of the surface 8 being cleaned, thus removing them from said surface and cleaning it due to a many times repeated treatment by the high-pressure jets of the working fluid (due to rotation of the rotor 4) for further use or subsequent treatment.
  • the cleaning efficiency is enhanced, insofar as first, the force of action exerted by the high-pressure jet upon the fouls deposits of the surface being cleaned is defined by a sum of the flow velocity of the working fluid high-pressure jet itself and of the rotation speed of the rotor 4 rather than by a difference therebetween which is the case with the Variant I of the invention, and secondly, the high-pressure jet is directed to the base of the deposits so as "to eradicate" them as it were.
  • said device for translational motion of the apparatus over the surface 8 being treated and for various manipulations therewith provision is made in both variants of the invention for a device for changing the direction of motion of the apparatus, said device per se may have, e.g., three construction arrangements, with the control mnemonics remaining unaffected in all the variants proposed herein.
  • Translational motion of the apparatus is effected due to a reaction force resulting from discharge of the working fluid from the ejector nozzles 19 in one direction, from the unidirectional nozzles 26, and from the hinged ejector nozzles 29.
  • the operator depresses the lever 25 on the control handle 21, thus acting upon through the control cable 24, or on the spring-actuated two-position directional control valve 22, or on the spring-actuated directional control valve 27, or on the spring-actuated swing cramp-iron 35.
  • the two-position directional control valve 22 moves in the barrel 23 to shut off one of the nozzles 19 in the pair and to turn on the other nozzle thereof.
  • directional control valve 27 also effects control over the feed of the working fluid to either of the nozzles 26 in the pair, and the processes proceeding as a result are similar to those described above. Partial shutting off of either of the nozzles 76 causes the apparatus to turn along a preset pathway and setting the apparatus on a parallel track to be cleaned in a reverse direction.
  • control cable 24 causes the tooth 36 of the spring-actuated swing cramp-iron 35 to disengage the stop dog 38.
  • the hinged nozzle 29 is urged by the reaction force resulting from the working medium discharging from said nozzle to turn through 180 degrees from one working position to the other until the opposite end 37 of the cramp-iron 35 is engaged with said stop-dog 38.
  • the herein-proposed apparatus is made from standard construction materials using routine production processes and can therefore be manufactured under standard production conditions.
