Description

  The present invention relates to a cleaning apparatus for cleaning a flexible object such as a pollution prevention film, a fishing net, an agricultural sheet, or a construction sheet.

  An apparatus is known in which a plurality of jet nozzles are provided on a head to efficiently clean an object (see Patent Documents 1 to 3). However, the objects to be cleaned by these cleaning devices are hard materials such as a scaffold plate, a universal plate, and a scaffold frame, and the material itself hardly deforms unless a large load is applied.

  Therefore, even if these objects are appropriately held, it is only necessary to take the shape as it is and to irradiate the cleaning liquid almost at right angles thereto. In terms of image, it is only necessary to remove the dirt.

  However, for example, when cleaning flexible objects such as antifouling membranes, fishing nets, agricultural or construction sheets, these flexible objects may overlap or undulate unless placed on a surface. Or twist, making cleaning difficult. This is because a flexible object cannot maintain its posture by itself.

  Furthermore, when the flexible object is net-like or fibrous, the cleaning effect is often insufficient simply by spraying the cleaning liquid at right angles to the flexible object. This is because even if the dirt adhered between the stitches and the fibers is washed, the dirt may reattach between the stitches and the fibers unless the dirt is washed away.

  From the above, when cleaning the flexible object, first prepare a wide inclined surface, place the flexible object on the inclined surface, and wash the inclined surface from the higher level. The dirt is allowed to flow along the inclined surface together with the cleaning liquid. In this way, the washed-out dirt is less likely to be reattached between the stitches and the fibers, so that the cleaning effect is improved. In the past, this operation has been performed by an operator supporting one nozzle by hand, and thus the operation time has been increased.

  Now, when a flexible object is placed on the inclined surface, the flexible object is positioned along the inclined surface, and accordingly, it is necessary to adjust the directions of the plurality of nozzles accordingly.

  When a plurality of nozzles are held by a holding member such as a head and the cleaning liquid is ejected from the plurality of nozzles, as a reaction, a force in the direction opposite to the jetting direction acts on the holding member. If the spraying direction of the cleaning liquid is constant (for example, vertical), it is easy to support the holding member so as to cope with this force (constant direction).

  For cleaning flexible objects, the direction of jetting is adjusted and changed, so the holding member must be able to accommodate changes in force caused by the reaction of jetting. But this is not easy.

To the extent that the prior art is slightly modified, there is a problem that the change in force cannot be dealt with, the movement of the holding member becomes unstable, and the cleaning effect becomes uneven. In addition, simply increasing the weight to increase the rigidity of the holding member results in an excessive load on the actuator (drive side) such as a motor, making it impossible to reduce the scale of the device and increasing the cost. There is also.

  Therefore, an object of the present invention is to provide a compact cleaning device that can efficiently clean a flexible object placed obliquely along an inclined surface.

  A cleaning device according to a first aspect of the present invention is a cleaning device for cleaning a flexible object placed on an inclined surface, the first vertical rail and the first vertical rail arranged so as to be orthogonal to the inclined surface. And a second vertical rail disposed so as to be orthogonal to the inclined surface at a position higher than the first vertical rail, a first frame capable of traveling along the first vertical rail, and a second vertical rail. A nozzle frame comprising: a second frame that can travel along the rail; a horizontal rail that connects the first frame and the second frame along the inclined surface; and a nozzle frame that traverses along the inclined surface along the horizontal rail. Holds a plurality of injection nozzles for injecting a cleaning liquid onto a flexible object so as to be inclined with respect to the nozzle frame, and the horizontal rail has an H-shaped cross section and is positioned in parallel with the inclined surface at an interval. Upper piece and horizontal lower piece, horizontal upper piece and horizontal lower piece The upper part of the nozzle frame is provided with an upper roller in contact with the upper surface of the horizontal lower piece and a lower roller in contact with the lower surface of the horizontal lower piece. The lower roller is supported by the horizontal frame by sandwiching the horizontal rail.

  In this configuration, the first vertical frame, the second vertical frame, and the horizontal rail can travel integrally in a direction (vertical direction) orthogonal to the inclined surface.

  The nozzle frame can traverse in the horizontal direction perpendicular to the vertical direction along the horizontal rail.

  A plurality of spray nozzles that spray the cleaning liquid onto the flexible object are held in a tiltable manner by the nozzle frame. Therefore, the angle of the nozzle frame can be changed in accordance with the inclination of the inclined surface. However, if the angle is changed, the direction of the force received by the nozzle frame changes as a result of the reaction of the plurality of injection nozzles injecting the cleaning liquid.

  However, the upper part of the nozzle frame is provided with an upper roller in contact with the upper surface of the horizontal lower piece of the horizontal rail and a lower roller in contact with the lower surface of the horizontal lower piece, and the upper roller and the lower roller sandwich the horizontal rail. The nozzle frame is supported by the horizontal frame.

  For this reason, even if the direction of the force applied to the nozzle frame changes, the upper roller and the lower roller hold the horizontal rail vertically so that the nozzle frame can maintain a stable posture and can be cleaned. Hard to cause unevenness.

  Further, these roller clamping mechanisms are compact mechanisms and do not increase the weight of the nozzle frame. Therefore, the load on the actuator can be reduced, and the overall size of the cleaning device can be reduced.

  In the cleaning device according to the second aspect of the invention, the pair of side rollers that are in circumferential contact with both side portions of the horizontal lower piece are rotatably supported on the upper portion of the nozzle frame.

  With this configuration, the pair of side rollers can sandwich the horizontal lower piece of the horizontal frame from both sides, and the horizontal shake phenomenon of the nozzle frame can be effectively suppressed, and the posture stability of the nozzle frame can be further improved.

  In the cleaning apparatus according to the third aspect of the present invention, a lateral motor is provided in the nozzle frame, a lateral gear driven by the lateral motor is rotatably supported with respect to the nozzle frame, and a gear chain that meshes with the lateral gear on the lateral rail. To stretch.

  With this configuration, the nozzle frame can be moved in the lateral direction by a simple and lightweight member.

  According to the present invention, even if the direction of the plurality of nozzles is changed and the direction of the force received by the nozzle frame is changed, the nozzle frame can maintain a stable posture by the sandwiching structure between the upper roller and the lower roller, Uneven cleaning.

  Further, the weight of the nozzle frame is not excessive, and the load on the actuator can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view of a cleaning device according to an embodiment of the present invention, FIG. 2 is a front view of the cleaning device, FIG. 3A is a left side view of the cleaning device, and FIG. FIG. 4 is an enlarged view of the vicinity of the nozzle frame of the cleaning device, FIG. 5A is a cross-sectional view of FIG. 4A-A, and FIG. 5B is FIG. 5A. 6A is a cross-sectional view of FIG. 4B-B, FIG. 6B is a front view of FIG. 6A, FIG. 7A is a cross-sectional view of FIG. 4C-C, and FIG. FIG. 7B is a front view of FIG.

  As shown in FIG. 2, the inclined surface 1 is prepared for cleaning the flexible object 3. A drainage groove 2 is appropriately provided at a low portion of the inclined surface 1 to ensure drainage. That is, the cleaning liquid that cleans the flexible object 3 and contains dirt flows down along the inclined surface 1, is collected in the drainage groove 2, and is discharged further downstream.

  In this embodiment, a pollution prevention film is taken up as an example of the flexible object 3. Anti-pollution membranes are installed in the sea, ponds, or water that is dammed by dams, and are used to prevent oils and other contaminants from diffusing outside the anti-pollution membranes. And a curtain portion 3b that hangs downward from the float portion 3a.

  As for the size of the pollution prevention film, the length of the float portion 3a is about 20 meters, and the length of the curtain portion 3b is about 20 meters at the maximum. Of course, these numerical values are merely examples, and the present invention is not limited to these numerical values.

  Moreover, a fishing net, an agricultural sheet, a building work sheet, or the like can be adopted as the flexible object 3, and at that time, the size is assumed to be smaller than the above.

  Now, in the anti-pollution film, the curtain part 3b is most easily stained. This is because oysters, seaweeds and the like are likely to adhere to this part. Of course, not only the curtain part 3b but also the float part 3a may be washed.

  The cleaning effect can be obtained by adjusting the angle of the plurality of injection nozzles 12, the distance between the nozzles, or the moving speed of the nozzle frame 11 (preferably controlled independently in the vertical and horizontal directions) in view of the degree of contamination of the flexible object 3. Can be improved.

  Here, high-pressure water is considered as the cleaning liquid, but a cleaning agent, a bleaching agent, a surfactant, and the like may be added as appropriate. In the present invention, the high-pressure water generator, the supply path to the injection nozzle 12, and the like are not essential, and since these may be known means, description thereof will be omitted.

  The first vertical rail 4 is laid at a low position of the inclined surface 1 in a direction orthogonal to the inclined surface 1 (in this specification, this direction is referred to as “vertical direction” for convenience).

  A second vertical rail 5 is laid in the vertical direction in parallel with the first vertical rail 4.

  As shown to Fig.3 (a), the lower end part of the 1st flame | frame 6 is installed on the 1st vertical rail 4 so that driving | running | working is possible.

  Similarly, as shown in FIG. 3B, the lower end portion of the second frame 7 is installed on the second vertical rail 5 so as to be able to run.

  As apparent from a comparison between FIGS. 3A and 3B, the first frame 6 is configured to be taller than the second frame 7 in accordance with the inclination of the inclined surface 1.

  The upper part of each of the first frame 6 and the second frame 7 is connected by a connecting beam 8 and a horizontal rail 9, and the first frame 6, the second frame 7, the connecting beam 8 and the horizontal rail 9 are integrated in the vertical direction. Can be moved to.

  As shown in FIG. 1, a lower portion of the first frame 6 is provided with a first vertical roller 6 a that surrounds the first vertical rail 4 and a first traveling motor 6 b that drives the first vertical roller 6 a. The pair of left and right first lateral slip prevention rollers 6c sandwich the side portion of the first vertical rail 4 to prevent lateral slip when the first frame 6 moves.

  Similarly, a second vertical roller 7a that surrounds the second vertical rail 5 and a second traveling motor 7b that drives the second vertical roller 7a are provided at the lower portion of the second frame 7, and a pair of left and right motors are further provided. The second lateral displacement prevention roller 7c sandwiches the side portion of the second vertical rail 5, and the lateral displacement when the second frame 7 moves is prevented.

  Next, the configuration in the vicinity of the nozzle frame 11 will be described in detail with reference to FIGS.

  First, as shown in a sectional view in FIG. 5A, the horizontal rail 9 of this embodiment has an H-shape (however, rotated 90 degrees) having a horizontal upper piece 9a, a horizontal lower piece 9b, and an upright piece 9c. .) Rail member.

  A gear chain 10 parallel to the horizontal rail 9 is stretched over the entire length of the horizontal rail 9.

  As shown in FIG. 4, the lateral motor 13 is fixed above the nozzle frame 11, and the lateral gear 14 driven by the output shaft of the lateral motor 13 meshes with the lateral motor 13.

  A support mechanism for supporting the nozzle frame 11 on the horizontal rail 9 will be described later. Basically, the support mechanism is configured such that the nozzle frame 11 is movable in the longitudinal direction (that is, the horizontal direction) of the horizontal rail 9. Support.

  Therefore, when the lateral motor 13 is driven, the lateral gear 14 rotates and the lateral gear 14 meshes with the gear chain 10, so that the nozzle frame 11 moves in the forward and backward directions.

  As shown in FIG. 4, the plurality of injection nozzles 12 are held by the nozzle frame 11, and when the handle 15 is rotated, the inclination angle of the injection nozzle 12 with respect to the nozzle frame 11 and the interval between the injection nozzles 12 can be adjusted. It is like that.

  Therefore, the injection nozzle 12 can move in the vertical direction by driving the first travel motor 6b and the second travel motor 7b, and can be moved in the horizontal direction by driving the horizontal motor 13. In short, the injection nozzle 12 can move in the XY direction with respect to the flexible object 3, and the moving speed can be adjusted while watching the degree of dirt.

  Next, a support mechanism for supporting the nozzle frame 11 on the horizontal rail 9 will be described.

  As shown in FIG. 4, the nozzle frame 11 is firmly supported by the horizontal rail 9 by the following three systems of rollers, which are a pair of left and right in the front view of FIG. 4, and the direction of the injection nozzle 12 is changed. Even if the direction of the force due to the reaction changes, it is stable.

  The first roller group is the upper roller 16 shown in FIGS. 5 (a) and 5 (b). That is, the pair of left and right shaft support portions 16 a are fixed upward in the uppermost portion of the nozzle frame 11 on the outermost side.

  Further, as shown in FIG. 5A, a pair of left and right upper rollers 16 are rotatably supported by the shaft support 16a.

  The peripheral surface of the upper roller 16 is in contact with the upper surface of the horizontal lower piece 9b of the H-shaped horizontal rail 9. Furthermore, you may make it the surrounding surface of the upper roller 16 contact | abut also to the lower surface of the horizontal upper piece 9a.

  The second is the lower roller 17 shown in FIGS. 6 (a) and 6 (b). In other words, the pair of left and right shaft support portions 17 a are fixed upward in the upper portion of the nozzle frame 11 inside the shaft support portion 16 a.

  Further, as shown in FIG. 6A, a pair of left and right lower rollers 17 are rotatably supported on the shaft support portion 17a.

  The circumferential surface of the lower roller 17 is in circumferential contact with the lower surface of the horizontal lower piece 9b of the H-shaped horizontal rail 9. As a result, the upper and lower surfaces of the horizontal lower piece 9b are firmly held between the upper roller 16 and the lower roller 17, and as a result, the spray nozzle 12 sprays from the cleaning liquid, resulting in the nozzle frame 11 being ejected. The nozzle frame 11 can maintain a strong resistance against the acting force, and can sufficiently follow even if the direction of the force changes.

  The third is the side roller 18 shown in FIGS. 7A and 7B. That is, the pair of left and right shaft support portions 18 a are fixed upward in the uppermost part of the nozzle frame 11 at the innermost side.

  Further, as shown in FIG. 7A, a pair of left and right side rollers 18 are rotatably supported by the shaft support 18a. However, unlike the upper roller 16 and the lower roller 17, the rotation axis of the side roller 18 is vertical.

  The peripheral surface of the side roller 18 is in contact with both side surfaces of the horizontal lower piece 9b of the H-shaped horizontal rail 9. As a result, both side surfaces of the horizontal lower piece 9b are clamped by the pair of left and right side rollers 18, and a lateral shift when the nozzle frame 11 moves (laterally) along the horizontal rail 9 is prevented.

  The layout shown in FIG. 4 is desirable for the layout of the three roller groups described above, but there is no practical problem even if it is changed as appropriate.

  The cleaning apparatus of the present invention can be suitably used, for example, in a technical field that evenly cleans pollution control films, fishing nets, agricultural or construction sheets, and other flexible objects.
