Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary nozzle device which is rotated by a reaction force of water or other jet liquid jetted from a nozzle, and more particularly to a high pressure water jet nozzle for washing vehicles, snow removal, pipes, tanks and buildings. The present invention relates to a rotary nozzle device that can be used as a high-pressure water jet nozzle for cleaning and also as a nozzle for airless painting.

2. Description of the Related Art In a cleaning device for spraying cleaning water from a spray nozzle to remove dirt adhering to the inside and outside surfaces of a vehicle, the spray pressure of the cleaning water is increased and a straight-ahead nozzle is used to increase the cleaning power. Although the injection pressure per unit area is increased, if such a configuration is adopted, the cleaning area is inevitably narrowed and a decrease in cleaning efficiency cannot be avoided. For this reason, the injection nozzle is attached to a rotatable support, the injection direction of the nozzle is arranged so as to be deflected with respect to the rotation axis of the support, and the reaction force of the injection pressure injected from the nozzle is used. A rotary nozzle device has been proposed in which the nozzle is rotated or swung to expand the injection area.

However, in such a rotary nozzle device, since the rotation speed of the nozzle is determined by the injection pressure, the higher the injection pressure, the higher the rotation speed. On the other hand, since the nozzle is eccentric with respect to the rotation axis of the support, a centrifugal force acts in a direction orthogonal to the rotation axis due to the rotation of the nozzle, and the centrifugal force increases in proportion to the rotation speed. .. The centrifugal force thus increased acts not only on the jet water flow ejected from the nozzle, but also impedes the straightness of the jet water flow, and scatters the jet water flow that is advancing straight into a mist state. I will end up. Then, even if the once atomized water flow maintains its ejection speed and collides with the vehicle, the impact force is significantly reduced, and the cleaning efficiency is significantly reduced.

In order to eliminate such a drawback, it is possible to tightly engage the nozzle with the support to save the rotational force thereof. In the above, the nozzle does not rotate smoothly, and therefore, in order to forcibly rotate the nozzle, the nozzle injection pressure is set to a high pressure that allows the nozzle to rotate in the initial stage of startup, and after the nozzle has rotated, the nozzle is steadily rotated. It is necessary to return the pressure to the pressure, the control operation becomes more complicated than necessary, and the pressure resistance strength of the device itself must be high enough to withstand the high pressure at the initial stage of startup.

[0005]

In view of the above-mentioned drawbacks of the prior art, the present invention does not atomize the jet flow of water by centrifugal force even when jetting washing water of high pressure with a simple structure, and the straightness thereof is improved. It is to provide a rotary nozzle device that can maintain the above. Another object of the present invention is to provide a rotary nozzle device in which the nozzle can be easily rotated with a steady injection pressure even in the initial stage of startup.

Another object of the present invention is to provide a rotary nozzle device which can be applied to paints, oils, etc. without limiting the jetting medium to only washing water.

The frictional resistance can be increased in proportion to the increase of the centrifugal force generated by the rotation of the nozzle mounting body 16.

Further, in FIG. 7 corresponding to the invention of claim 3, the rotation suppressing means is formed by a blade body 66 provided on the outer peripheral wall surface of the nozzle mounting body 16, and the pressure receiving area of the blade body 66 is the nozzle. It is configured such that it can be increased in proportion to an increase in centrifugal force generated by the rotation of the mounting body 16.

Further, in FIG. 8 corresponding to the invention of claim 4, there are shown magnet bodies 71-72 provided at the facing positions between the nozzle mounting body 16 and the main body 11, respectively. 7
The rotational force of the nozzle mounting body 16 can be suppressed by the repulsive magnetic field formed between the two. Further, in FIG. 9 corresponding to the invention of claim 5, the rotation suppressing means is
The fluid introduced to the nozzle is composed of a relief valve that can be opened by centrifugal force generated by the rotation of the nozzle mounting body, and the relief valve is sealed when the nozzle mounting body is not rotating, and is proportional to the increase in the number of rotations of the nozzle mounting body. 10 and 11 corresponding to the invention of claim 6, the rotation suppressing means mounts the steel ball accommodating hole to the nozzle. A plurality of recesses are formed in the circumferential direction of the outer peripheral surface of the body, and a slightly smaller steel ball is housed in the housing hole, and fixed to the main body while facing the outer peripheral surface of the nozzle mounting body through a predetermined gap. On the outer body side, a shallow arc-shaped concave groove is provided at a selected position in a position facing the steel ball 81, and the steel ball is configured to be engageable with the steel ball 81. To do.

[0011]

In any of the above-mentioned inventions, the rotation suppressing means 50 to 85 are provided at a position radially separated from the axis C of the nozzle mounting body 16 by a predetermined distance.
Since the rotation suppressing means 50 to 85 can be increased in proportion to the increase in the rotation speed of the nozzle mounting body 16,
Even when high-pressure washing water is sprayed from the straight-ahead nozzle 7, the rotational speed is suppressed by the means, so that a centrifugal force sufficient to atomize the sprayed water flow does not occur, and as a result, its straightness is improved. Can be maintained. Also, the rotation suppressing means
Since the suppression force of 50 to 85 is configured to start from a substantially no-load state, it can be easily started even with a steady injection pressure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described in detail below as an example with reference to the drawings. However, unless otherwise specified, the dimensions, materials, shapes, relative positions, etc. of the components described in this embodiment are not intended to limit the scope of the present invention thereto, but are merely illustrative examples. Not too much. Figure 1
Is a rotary nozzle device to which the present invention is applied, (A) is a left side view, (B) is a vertical sectional front view, and (C) is a right side view.
In the figure, 1 is a main body in which a high-pressure fluid source can flow into the inside by screwing a pressure-resistant hose into the inlet, and the outer ring of the rolling bearing 3 including the bearing is covered by a sleeve 2 in which the outer ring side of the tip is screw-engaged. Tighten 3a together with packing retainer 4. The support body 5 is press-fitted and fixed to the inner ring of the rolling bearing 3 and is rotatably supported by the main body 1 via the rolling bearing 3, and the support body 5 is in fluid communication with the main body inflow port 1a facing open. A main body between the inflow port 1a and the rolling bearing 3 which has a space 5a and a pressure resistant seal interposed in the base side cylindrical portion thereof.
1 In addition to blocking the internal space, an upper part is opened on the side protruding from the main body 1 via a hexagonal flange 5b, and a gas screw is engraved on the outer periphery to provide a tubular body 5c. 5c is provided at a position deviated from the rotation axis M of the support 5 (the axis of the rolling bearing 3).

As a result, the rotation axis M of the main body 1 side support body 5 and the cylindrical body axis center α are eccentric as shown in FIG. 1 (A). After a tape seal is wound around the outer periphery of the tubular body, a cap-shaped nozzle mounting body 6 (hereinafter referred to as a cap) is rotatably screwed. The cap 6 is screwed with a straight-moving nozzle 7 having a rectifying piece 7a on the inlet side, and
The nozzle 7 is obliquely arranged so as to point the axis C α of the cap 6.

In the above structure, when the cap 6 is rotated by α (for example 130 °) on the support 5 with a screw as shown in FIG. 1A, the center O of the tip of the nozzle 7 becomes O '.
Move to. If M is the rotation center axis of support 5, OM
Indicates the maximum offset amount, and O'-M indicates the minimum offset amount. Since the offset amount is changed by rotating the cap 6 on the support 5 in this manner, the rotation speed and the injection area of the nozzle 7 rotated by the injection reaction force can be controlled.
A rectifying piece 7a is inserted into the inlet of the nozzle 7. The rectifying piece 7a is formed by bending a thin metal plate into a star shape, for example, and is inserted and attached to the inlet of the commercially available nozzle 7. Its action is as follows. The introduced high-pressure hot water expands in volume in the support 5 cap and flows to the nozzle 7. Due to this volume expansion, a turbulent flow is generated in the fluid, and if the turbulent flow is used to eject from the nozzle 7, the ejection angle becomes wider than the set value, and the impact (cleaning effect) is reduced. When the rectifying piece 7a is incorporated, the turbulent fluid is conditioned while passing through the rectifying piece 7a, and the above-mentioned drawbacks are prevented.

2 (A) and 2 (B) show an example of application of the rotary nozzle 7 device of the present invention, which is an oscillating type side film portion cleaning device 4.
Shows the overall view of the column lift installation, 21 is a rotary nozzle device,
A distribution block 22 is provided with the rotary nozzle device 21, and is mounted at an arbitrary position with respect to the forward / reverse rotation shaft 24 by a knob 23 to set a cleaning height. The motor 24 rotates the shaft 24 forward and backward.
Rotating plate 26, connecting rod 2 driven by deceleration by
7. This is performed by the forward / reverse rotation piece 28. This device does not become an obstacle when entering because the vehicle lifts up,
As the position where the cleaning effect is most effective, it is installed on each side of the four-column lift moving side carriage for automatic cleaning.
Since the height and angle of the nozzle device 21 can be arbitrarily adjusted in the range of automatic cleaning, the cleaning range can be set depending on the vehicle type. Further, by providing a lateral swing mechanism, the cleaning range can be further expanded and the cleaning effect can be increased.

FIG. 3 is a perspective view of a lower washing machine self-feeding type apparatus as another application example of the rotary nozzle 7 apparatus of the present invention. In the conventional lower cleaning device, the nozzle of the nozzle arm is set, the nozzle arm is housed in the main body, and the nozzle arm is moved forward or backward. No cleaning effect was obtained. According to this apparatus, a good cleaning effect can be obtained by expanding the cleaning area and overlapping cleaning because the cleaning angle is wide, regardless of the condition of cleaning the upper part from below. In the figure, 31 is a rotary nozzle device of the present invention, which is attached to the distribution block 32 in the protective cover 33, swings the nozzle arm 34, and further expands the nozzle arm 34 to repeat the operation to expand the cleaning area, and to rotate the rotary nozzle. Overlapping cleaning is performed by the device 31. As described above, since the nozzle arm 34 swings and traverses, the method of driving the rotary nozzle device 31 by the external power becomes a very complicated mechanism. By using the rotary nozzle device 31 of the present invention, the energy of the fluid is used for rotation without using any complicated mechanism.

FIG. 4 is a rotary nozzle device showing an embodiment of the second invention incorporated in the cleaning device, (A) is a plan view,
(B) is a vertical sectional front view. Reference numeral 11 in the drawing is a main body 11 configured to allow a high-pressure fluid source to flow therein by screwing a pressure-resistant hose into the inflow port 1a, and has a cylindrical concave portion for accommodating the nozzle mounting body 16 (hereinafter referred to as the rotor 16) on the upper surface side.

In the figure, 14 is an escape hole for the fluid leaked from the seal packing, 15 is a drain cover, and 17 is a snap ring that functions as a stopper of the rolling bearing 3. On the other hand, the rotor
16 The upper part is formed with an outer diameter slightly smaller than the inner wall surface 12a of the cylindrical recess of the outer casing 12, and a straight-ahead nozzle 7 provided with a rectifying piece 7a is screwed onto the upper surface thereof, and the nozzle 7 is attached to the rotor 16 of the rotor 16. It is arranged diagonally so as to point the axis C and slightly inclined in the circumferential direction. Then, in order to connect the central through hole 11a on the main body 11 side and the straight-ahead nozzle 7 with each other, the rotor
A through hole 16b is bored in the inner part 16. As a result, the central through hole
By introducing a high-pressure fluid into 11a, the rotor 16 is rotated by the injection pressure from the nozzle 7.

The rotor 16 is provided with a plurality of U-shaped grooves 52 at positions separated by a predetermined angle on the outer peripheral surface facing the outer casing 12, and the U-shaped grooves 52 are provided in the U-shaped grooves 52. A cylindrical body 51 having the same shape as the diameter is housed, and an O-ring 54 is wound around an outer peripheral surface of the rotor 16 and a ring groove 53 formed on the peripheral surface of the cylindrical body 51, so that the cylindrical body 51 is predetermined on the U-shaped groove 52 side. It is held by the elastic force of. As a result, in the non-rotating state of the rotor 16, the cylindrical body 51 is
It is possible to maintain a non-contact state with the inner wall surface 12a of the outer cover 12. A cap 18 having a U-shaped cross section is attached to the upper surface of the rotor 16 to conceal the U-shaped groove 52.

According to this embodiment, since the cylindrical body 51 is kept in non-contact with the inner wall surface 12a of the outer cover 12 when the rotation is stopped, the rotor is driven by the jet reaction force of the nozzle 7. 16 begins to rotate easily, and the cylindrical body 51 contacts and presses the inner wall surface 12a of the outer casing body 12 against the elastic holding force of the O-ring 54 by the centrifugal force generated by the rotation of the rotor 16.
The sliding resistance suppresses the rotation of the rotor 16,
Since the sliding resistance increases in proportion to the increase in the number of rotations of 16, the rotation speed is consequently suppressed, the centrifugal force sufficient to atomize the jet water is not generated, and the straightness is maintained. Can be done.

FIG. 5 shows another embodiment using a lining shoe, in which the free end 56a side is folded back in two and overlapped with the inner wall surface 12a of the outer casing 12 to a non-contact state.
56, a cylindrical body 57 to which the base end side of the lining shoe 56 is fixed, and a cylindrical recess 58 recessed on the outer peripheral surface of the rotor 16 to house the cylindrical body 57 constitute a rotation suppressing means. ..
According to such an embodiment, when the rotation is stopped, the lining shoe 56 maintains a non-contact state with the inner wall surface 12a of the outer casing 12, and even if the lining shoe 56 makes a slight contact, the lining shoe 56 has a low resistance. Therefore, the rotor 16 easily starts to rotate due to the injection reaction force of the nozzle 7, and the lining shoe 56 is pushed by the pressing force of the cylindrical body 57 due to the centrifugal force generated by the rotation of the rotor 16. The inner wall surface 12a is pressed against the inner wall surface 12a, the rotation of the rotor 16 is suppressed by the sliding resistance, and the sliding resistance is increased in proportion to the increase in the number of rotations of the rotor 16, so that the rotation speed is suppressed. , Produces the same effect as described above.

FIG. 6 shows another embodiment using a turbine brake mechanism, in which the rotor 16 center tube 11b is fitted to the inner wall surface 12a of the outer casing 12.
A disk member 60 having a sliding piece 61 whose end is branched in an eight shape is provided at the extended position, and a weight 63 is provided at both ends of the sliding piece 61. The sliding piece 61 is attached so that the sliding piece 61 can be closed by a centrifugal force acting on the weight 63. On the other hand, hemispherical friction balls 62 having a plurality of radii are provided on the inner wall surface 12a side of the outer casing 12 at a position facing the sliding piece 61 along the circumferential direction. According to this embodiment, since the hemispherical friction ball 62 and the sliding piece 61 are kept in non-contact with each other when the rotation is stopped, the injection reaction force of the nozzle 7 causes the rotor 16 to rotate.
Of the sliding piece 61 which starts to rotate easily and which is expanded in the shape of an eight by the centrifugal force generated by the rotation of the rotor 16.
Is blocked and rubs against the friction ball 62, the rotation of the rotor 16 is suppressed by its sliding resistance, and the sliding resistance increases in proportion to the increase in the number of rotations of the rotor 16. The rotation speed is suppressed, and the same effect as described above is generated.

FIG. 7 shows another embodiment using the blade 66,
A plurality of vertical shafts 67 are attached to the outer peripheral surface of the cap 18 that rotates integrally with the rotor 16 along the circumferential direction, and the blade bodies 66 are attached to the shafts 67 with screws. The blade body 66 is formed of a stainless steel plate, and extends along the outer peripheral surface of the cap 18, and then the free end 66a is folded back to form a pressure receiving surface 66b. According to such an embodiment, when the rotation is stopped, the free end 66a side of the blade body 66 is overlapped by 180 ° and folded back, so that the pressure receiving area is small. Therefore, in this state, the nozzle 7 The rotor 16 easily starts to rotate due to the jet reaction force, and the centrifugal force generated by the rotation of the rotor 16 and the rotating wind force cause the blade body to be folded back in such a manner that it overlaps by 180 degrees.
66 The free end 66a rises in the radial direction against the elastic force of the blade body 66 itself and suppresses the rotation of the rotor 16 by its wind force resistance, and the free end is proportional to the increase in the rotation speed of the rotor 16.
Since the pressure receiving area of 66a increases and its wind resistance increases, the rotation speed is consequently suppressed and the same effect as described above is generated.

FIG. 8 shows another embodiment in which the repulsive magnetic field of the magnet is utilized. Magnets 71-72 of the same polarity are respectively provided at positions where the inner wall surface 12a of the outer casing 12 and the outer peripheral surface of the rotor 16 face each other. Install more than one. According to such an embodiment, when the rotation is stopped, the magnetic body 71-7 is moved by the repulsive magnetic field between the magnetic bodies 71-72.
The two are located farthest apart from each other in the circumferential direction.Therefore, in this state, the influence of the magnetic field is almost negligible.Therefore, the injection reaction force of the nozzle 7 easily starts the rotor 16. When the magnets 71-72 come to a position where they face each other after the start-up, the rotational force is suppressed, and as the rotational speed further increases, the face-to-face frequency increases proportionally. Is proportionally suppressed, the centrifugal force sufficient to atomize the jet water is not generated, and the straightness can be maintained.

FIG. 9 shows another embodiment using a relief valve.
A through hole 16b in the rotor 16 for guiding the high-pressure fluid to the nozzle 7.
A small hole 75 communicating with the hole is formed in the radial direction from the center position, and the escape hole 77 is vertically penetrated to the exit side of the closed space 76 through the taper sheet surface 76a at the exit side thereof to reach the upper surface position. A steel ball 79, which is elastically biased by a spring 78 in the direction opposite to the centrifugal force, is housed in 76, and the steel ball 79 is brought into contact with and sealed to the seat surface 76a, and the small hole 75 and the escape hole are provided. It cuts off between 77. According to this embodiment, when the rotation is stopped, the rotor 16 maintains the non-contact state with the inner wall surface 12a of the outer casing 12, so that the rotor 16 can be easily moved by the injection reaction force of the nozzle 7. Begins to rotate, and the rotor
The centrifugal force generated by the rotation of 16 acts on the steel ball 79,
When the rotation speed becomes higher than the spring 78 pressure, the steel ball 79 and the seat surface 76a are slightly separated from each other, and a part of the high-pressure fluid flowing in the conduction hole 16b passes through the escape hole 77 from the small hole 75 to the outside. Escape, the rotation of the rotor 16 is suppressed by the decrease of the fluid pressure, and the separation distance between the steel ball 79 and the seat surface 76a increases in proportion to the increase in the rotation speed of the rotor 16, so that the fluid escapes. The amount is even greater, and as a result the rotational speed is suppressed, producing the same effect as above.

FIG. 10 shows another embodiment in which a hall brake is used. A plurality of steel ball storage holes 83 are formed in the outer circumferential surface of the rotor 16 in the radial direction, and are slightly smaller in the storage holes 83. After housing the steel ball 81, a stopper 85 is attached to the outer peripheral end of the steel ball 81 to prevent the steel ball 81 from coming off, and an O-ring 84 is wound around the lower outer peripheral surface of the steel ball 81 to facilitate the rotation of the rotor 16. On the other hand, on the inner wall surface 12a side of the outer casing 12, a shallow arc-shaped groove 82 is formed at one or two selected positions (two positions 180 ° apart in the case of this embodiment) of the positions facing the steel ball 81. And the steel ball 81 can be engaged with the groove. According to such an embodiment, when the rotation is stopped, the steel ball 81 has the outer wall 12 and the inner wall surface 12
Since it is not in contact with a, the nozzle 7
The rotor 16 easily starts to rotate due to the injection reaction force of the steel ball 81, and the centrifugal force generated by the rotation of the rotor 16 causes the steel ball 81 to move to the outside of the storage hole 83, and a part of the steel ball 81 projects from the storage hole 83 Rotation of the rotor 16 is suppressed by repeating engagement and disengagement of the rotor 16 with engagement with the groove 82 and rotation of the rotor 16 and centrifugal separation in proportion to an increase in the rotation speed of the rotor 16. When the force becomes large, the pressing force applied to the steel ball 81 also becomes large, so the engagement strength between the steel ball 81 and the concave groove 82 increases, and as a result, the rotation speed is suppressed, Produces the same effect as.

FIG. 11 shows another embodiment in which the rotor 16 is rotatably supported by the lining seal material 19 with respect to the main body 11 without using the rolling bearing 3, and is made of steel similarly to the embodiment shown in FIG. A plurality of ball storage holes 83 are provided in the outer peripheral surface of the rotor 16, a slightly smaller steel ball 81 is stored in the storage hole 83, and an O-ring 86 is wound around the outer peripheral end of the steel ball 81.
