Definitions

  • the present invention relates to a hydro-cleaning device, that is to say a device for carrying out pumping of effluents, in particular in septic tanks or in sewers.
  • Devices of this type which exist on the market generally comprise a suction cistern, a suction pipe and pumping means making it possible to pump the effluents towards the suction cistern by means of the suction pipe.
  • Such a device can typically be mounted on a wheeled chassis, this chassis possibly taking the form of a trailer intended to be hitched to a towing vehicle, or else forming part of a self-propelled vehicle.
  • Such a hydro-cleaning device must be driven as close as possible to the site on which one wishes to carry out the pumping operations, the last meters towards the pumping zone being crossed by unrolling the suction pipe from a reel integral with the frame. or the suction tank of the device.
  • a hydro-cleaning apparatus of the type comprising a frame, a suction tank mounted on this frame, a suction pipe, means for pumping effluents by means of this pipe to the cistern, a suction reel for storing this suction pipe, this suction reel being rotatably mounted about a substantially vertical axis, between said frame and said suction tank.
  • the reel extends in a substantially horizontal plane, and can be placed between the frame and the suction tank, that is to say in a zone which does not increase not the size of the hydro-cleaning vehicle.
  • This vehicle can thus go into areas with difficult access, in particular to individuals to carry out septic tank or sewer pumping operations, which can be hindered for example by relatively low tree branches, or by other obstacles making access to these areas complicated for larger vehicles.
  • this suction reel which allows the turns of the suction pipe to remain in a substantially horizontal plane, makes it possible to limit or even eliminate the pressure drops of the pumped effluents, which can be observed in conventional devices. where the winding of the suction pipe is done around a substantially horizontal axis, and where consequently each turn induces a pressure drop on pumping.
  • the present invention also relates to a hydro-cleaning trailer, equipped with an apparatus in accordance with the above: such a trailer can be hitched to a tractor vehicle, in order to be driven over the pumping areas.
  • the present invention also relates to a self-propelled hydro-cleaning vehicle, equipped with an apparatus in accordance with the above: such a vehicle is completely autonomous, both in terms of pumping and movement.
  • an XYZ reference has been shown, in which the horizontal axis X is parallel to the longitudinal direction of the self-propelled vehicle according to the invention, the horizontal axis Y is perpendicular to this direction, and the axis Z is vertical.
  • horizontal designates a direction parallel to the XY plane
  • vertical a direction parallel to the Z axis
  • front and “rear” must be understood with respect to the direction of the arrow l X axis, this arrow pointing to the front of the device.
  • FIG. 1 , 2 , and 3 On which there is shown a self-propelled vehicle according to the invention, comprising a frame 1 mounted on axles provided with wheels 3, and supporting a hydro-cleaning device according to the invention 5.
  • This hydro-cleaning device 5 comprises a suction tank 7, a suction pipe 9 and pumping means not shown and located in a compartment machines 11 located at the front of the cistern 7, making it possible to suck in the pipe 9 effluents such as sludge or waste water towards the interior of the suction cistern 7.
  • this suction pipe 9 can typically have a diameter of 65 to 100 mm, and be provided at its end with a connector allowing it to be connected to pumping accessories (rigid suction pipe for example ).
  • the hydro-cleaning device according to the invention may also optionally comprise a high-pressure cleaning device, comprising a high-pressure pump not visible in these figures, but located in the area of the machines 11, and a high-pressure cleaning tank 13 located in front of the suction tank 7, which can contain a cleaning liquid such as water, and generally has a volume smaller than that of the suction tank 7.
  • a high-pressure cleaning device comprising a high-pressure pump not visible in these figures, but located in the area of the machines 11, and a high-pressure cleaning tank 13 located in front of the suction tank 7, which can contain a cleaning liquid such as water, and generally has a volume smaller than that of the suction tank 7.
  • this high-pressure cleaning device also comprises a hydraulically motorized reel 15 around which a high-pressure cleaning hose (not shown) is wound, this winding taking place around a substantially horizontal axis.
  • the diameter of the high pressure cleaning pipe is smaller than that of the suction pipe 9: this diameter can typically be of the order of % inch or 1 inch.
  • the high pressure reel 15 comprises a support 19 pivotally mounted on the suction tank between a folded position visible on the figure 1 , and a deployed position, visible on the figure 2 , and 3 , around a substantially vertical axis, that is to say substantially parallel to the Z axis.
  • This support 19 can typically be made of mechanically welded metal alloy.
  • the support 19 comprises a frame 21 provided with rollers, through which passes the suction pipe 9: during the rotational movement of the support 19 between its folded position and its deployed position, this frame 21 drives the suction pipe 9.
  • the hydro-cleaning device comprises a suction reel 23, around which the suction pipe 9 is wound, this reel being rotatably mounted on the frame 1 about a substantially vertical axis , i.e. substantially parallel to the Z axis.
  • Means for motorizing the hub 25 of the suction reel 23 are provided, so as to allow rotational movement of this reel without manual intervention.
  • These motorization means may comprise a hydraulic or electric motor in direct or reduced drive with the reel 23.
  • the suction cistern 7 and the suction pipe 9 make it possible to suck up effluents (sludge, waste water, etc.) originating for example from septic tanks or manholes.
  • effluents sludge, waste water, etc.
  • the hydro-cleaning device according to the invention is brought closer to the point of intervention.
  • the means for motorizing the reel of the suction pipe 23 are activated, so as to allow the end of the suction pipe 9 to be driven to the suction point. .
  • the support 19 is pivoted around its vertical axis, from its folded position ( figure 1 ) to its deployed position ( figure 2 and 3 ).
  • the end of the suction pipe 9 can be brought as close as possible to the suction zone, without excessive effort.
  • the pumping operations are then carried out, by starting the suction pump located in the machine part 11 of the hydro-cleaning apparatus according to the invention.
  • the effluent suction operation can be supplemented with a high-pressure cleaning operation, by means of the high-pressure cleaning hose (not shown), wound around the high-pressure reel 15: to do this, this high-pressure hose is unrolled and its end is brought to the area where the cleaning operations are to be carried out.
  • the high-pressure cleaning pump located in the machine zone 11 is then started, which makes it possible to project high-pressure water from the high-pressure tank 13 against the surfaces to be cleaned.
  • the high pressure cleaning hose is wound around the high pressure reel 15, then the support 19 is folded down towards its folded position against the rear of the suction tank 7.
  • the arrangement of the suction reel 23 and the suction pipe 9 horizontally on the frame 1 is under the suction tank 7, makes it possible to obtain a particularly compactness of the hydro-cleaning device: this reel and this hose do not increase the external size of the device, which makes it particularly agile to intervene in areas that are difficult to access, for example where there are lower branches.
  • the invention therefore makes it possible to obtain a device, and if necessary a trailer or a self-propelled vehicle equipped with such a device, which is particularly suitable for interventions in private homes (emptying of septic tanks in particular), where the accesses are often difficult.
  • the horizontal arrangement of the reel 23 makes it possible to eliminate pressure losses in the turns of the suction pipe 9, and therefore to use a suction pump of lesser power, with equal suction.
  • the optional guide means provided by the support 19, the frame 21 and, where appropriate, by the telescopic arm, greatly facilitate the manipulations of the operator to lead the end of the suction pipe 9 with precision towards the area of aspiration.
