Description

[0001] The present invention relates to a sprinkler having a head rotating at a predetermined angle,

The present invention relates to a sprinkler having a head rotating at a predetermined angle, and more particularly, to a sprinkler capable of minimizing an area in which water is sprayed by providing a plurality of nozzles on the head even when a partial rotation sprinkler is used .

Generally, golf courses artificially create obstacles such as forests, valleys, ponds, and mountains on a wide course, and use natural rivers or the sea. In addition, the golf course formed on the golf course is composed of a teeing ground, a fairway, a rough, a bunker, a water hazard, a green and a hole, and in most areas except the bunker and the water hazard, natural grass is planted.

Therefore, the manager of the golf course must provide good quality golf course to the golfers by continuously supplying sufficient moisture to the natural lawn. Therefore, the manager manages the lawn by installing a sprinkler that can supply water to the area except the water hazard (that is, where the lawn is planted).

The sprinkler used in a golf course can be divided into an impact type and a gear type according to a driving method. The shock-driven sprinkler rotates the head by pressing the head while the rotating arm alternately rotates clockwise and counterclockwise due to the impact of the water stream injected from the nozzle.

Such a shock-driven sprinkler can be divided into a part circle sprinkler and a full circle sprinkler according to the rotation angle of the head. The sprinkler for the part circle may include an angle adjusting member for adjusting the angle at which the head is rotated. The user can adjust the rotation angle of the head by operating the angle adjusting member.

The head is coupled with a nozzle for jetting water to the outside. In the sprinkler for a part circle according to the prior art, the nozzle is composed of one (see U.S. Patent No. 8,056,829). That is, in the conventional sprinkler for a part circle, water is sprayed only by the one nozzle, so that a dead space is generated in which water is not sprayed even when the sprinkler is operated.

Accordingly, there is a problem that the user must additionally install the sprinkler to spray the dead space, or spray the water directly to the dead space.

US Patent No. 8,056,839 (published on June 17, 2010)

SUMMARY OF THE INVENTION The present invention has been developed in order to overcome the limitations and disadvantages of the prior art as described above. Specifically, in a sprinkler for a part circle driven by an impact, a nozzle for spraying water on a head rotating by a rotation arm The present invention provides a sprinkler capable of minimizing dead space, which is a region where a plurality of water is not sprayed.

According to an aspect of the present invention, there is provided a bearing device comprising: a bearing sleeve having a passage for allowing water to pass therethrough along a longitudinal direction; a space communicating with the passage is formed in the bearing sleeve, A head rotatable about a longitudinal axis of the bearing sleeve; an angle adjusting member installed to surround an upper outer surface of the bearing sleeve, the angle adjusting member limiting a rotation angle of the head; a position crossing a predetermined angle inclined from the longitudinal axis; And a second nozzle coupled to the head at a location that intersects the first nozzle at an angle slant from the first nozzle about the longitudinal axis.

According to the present invention, since a plurality of nozzles having different directions are coupled to the head of the sprinkler, it is possible to minimize the area in which water is not sprayed even if a sprinkler for a part circle is used.

In addition, since the radius of the head is adjusted by the angle adjusting member, the user can manipulate the water spraying region by operating the angle adjusting member as needed.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby.

FIG. 1 is a perspective view showing an outer shape of a sprinkler according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a detailed structure of the sprinkler except a case. 3 is an exploded view showing the internal components of the sprinkler.

1 to 3, the sprinkler 1 according to the present embodiment includes a case 10 forming an outer appearance and a cover 20 covering an upper surface of the case 10. The cover 20 is spaced from the upper surface of the case 10 when the sprinkler 1 is operated and is seated on the upper surface of the case 10 when the operation of the sprinkler 1 is completed.

The case 10 can be divided into an upper portion and a lower portion according to the size of the inner diameter. On the upper portion of the case 10, a plurality of ribs 12 protruding from the outer surface and elongated in the longitudinal direction of the case 10 are formed. The plurality of ribs 12 serve to reinforce the strength of the case 10. In addition, the case 10 according to the present embodiment is made of an impact-resistant plastic, which is superior in strength and durability as compared with the conventional case.

A plurality of protrusions 11 projecting downward from the upper portion are formed on the upper surface of the case 10. For example, six protrusions 11 may be formed along the circumferential direction with respect to the lower surface of the upper portion. Each of the projections 11 is formed with a through hole for engaging a fastening member such as a screw. The coupling member sequentially passes through holes formed in the through hole 40a formed in the bearing guard 40 and the through hole formed in the projection 11 to fix the bearing guard 40 on the upper surface of the case 10 .

Inside the case 10, there is provided a bearing sleeve 30 movable in the vertical direction by water pressure. When the water flows into the case 10, the bearing sleeve 30 is moved upward by the water pressure, and the up and down movement of the bearing sleeve 30 is surrounded by the outer surface of the bearing sleeve 30 And is guided by the guide member 32. A check valve (500) for controlling the movement of water and a wire netting (400) for preventing the inflow of foreign matter other than water are installed in the lower part of the bearing sleeve (30).

The upper surface of the bearing guard 40 surrounding the outer surface of the bearing sleeve 30 is provided with a bearing guard 40 for preventing foreign matter from entering through the space formed between the inner surface of the bearing guard 40 and the outer surface of the bearing sleeve 30. [ A guard packing 41 may be provided.

A head 100, which is rotatable with respect to the bearing sleeve 30, is installed on the bearing sleeve 30. The head 100 is provided with a plurality of nozzles 101 and 102 for jetting water moved along the inner space of the bearing sleeve 30 to the outside.

Each of the plurality of nozzles 101 and 102 may be provided with a nozzle cover 102a for covering an ejection port formed in the nozzles 101 and 102.

At one side of the head 100, a locking member 310 and a connecting member 320, which move relative to each other to limit the rotation angle of the head 100, are coupled. The head 100 is coupled to the connecting member 320 by the head shaft 340 and the connecting member 320 is engaged with the engaging member 310 by the tension adjusting member 330. [

Therefore, when the engaging member 310 rotates clockwise, the connecting member 320 rotates in the counterclockwise direction by the elastic force provided by the tension adjusting member 330, and the engaging member 310 rotates counterclockwise The connecting member 320 rotates in the clockwise direction.

The engaging member 310 may be in contact with a plurality of angle adjusting members 500 surrounding the upper outer surface of the bearing sleeve 30. The angle adjusting member 500 includes a first adjusting member 51 for limiting a rotation angle of the head 100 in one direction (clockwise direction in FIG. 2) 2 counterclockwise in the reference). That is, the rotation angle of the head 100 is changed from a point at which the first adjusting member 51 and the engaging member 310 are in contact to a point at which the second adjusting member 52 and the engaging member 310 contact each other As shown in FIG.

A predetermined hole is formed in the head 100, and a pivoting arm 200 rotatable by water pressure is installed in the hole. The pivoting arm 200 can be coupled with the head 100 by a shaft 370 through the hole. The pivot arm 200 may be rotatably coupled to the head 100 by an elastic member 350 disposed in the hole. That is, the pivot arm 200 is coupled to one side of the elastic member 350, and the head 100 is coupled to the other side of the elastic member 350.

Hereinafter, the process of performing the rotational movement of the head 100 will be described in detail, and the process of spraying water to the outside by the plurality of nozzles 101, 102 in accordance with the rotational movement of the head 100 I will explain.

FIG. 4 is an explanatory view illustrating an operation of rotating the head of the sprinkler in a clockwise direction, and FIG. 5 is an explanatory view illustrating an operation of rotating the head of the sprinkler in a counterclockwise direction.

4A shows a state in which the engaging member 310 engaged with the head 100 is in contact with the second adjusting member 52. As shown in Fig. When the water is injected through the nozzles 101 and 102 coupled with the head 100, the rotating arm 200 rotates in the counterclockwise direction by water pressure (see (1) in FIG. 4B).

At this time, the pivot arm 200 rotates in a counterclockwise direction without interfering with the coupling member 320 engaged with the locking member 310 (see A in FIG. 4B). When the rotation arm 200 is rotated in the counterclockwise direction by a predetermined angle, the elastic member 350 applies a predetermined elastic force to the rotation arm 200 so that the rotation arm 200 is rotated clockwise (See (2) in Fig. 4B). Accordingly, the pivoting arm 200 presses one side of the head 100, and the head 100 is gradually rotated clockwise by this pressing force. Accordingly, the latching member 310 is moved from the second adjusting member 52 to the first adjusting member 51 (see FIG. 4C).

When the pivoting arm 200 hits the head 100 in a state where the pivoting member 310 is in contact with the first adjusting member 51, the pivoting member 310 rotates clockwise, The connecting member 320, which rotates relative to the engaging member 310, rotates counterclockwise (see FIG. 4C).

In this state, when water is injected through the nozzles 101 and 102, the rotary arm 200 rotates counterclockwise by the water pressure. However, when the angle of rotation of the rotary arm 200 in the counterclockwise direction exceeds a certain range, one side of the rotary arm 200 is in contact with one side of the connection member 320 See B).

Accordingly, the head 100 coupled to the connecting member 320 is moved in the counterclockwise direction according to the rotation of the pivoting arm 200 (see FIG. 5B) 2 regulating member 52 (see Fig. 5C).

Thus, the head 100 of the sprinkler according to the present embodiment can perform rotational movement only at a certain angle. However, in the related art, there is a problem that the nozzles of the head 100 are formed as one unit, and the spraying range of the water sprayed through the nozzles is narrow.

According to the present embodiment, since the plurality of nozzles 101 and 102 are provided in the head 100 of the sprinkler rotating at a predetermined angle, the jetting range of water sprayed through the nozzles 101 and 102 can be widened .

Specifically, the water introduced into the bearing sleeve 30 moves to the head 100 having the plurality of nozzles 101 and 102. As shown in FIGS. 2, 4 and 5, the head 100 includes a first nozzle 101 that engages with the head 100 at a position that intersects the z axis at a predetermined angle inclination, A second nozzle 102 is provided at a position intersecting the first nozzle 101 at a predetermined angle with respect to the z-axis with respect to the xy plane.

The second nozzle 102 is coupled to the head 100 in a direction perpendicular to the first nozzle 101 with respect to the xy plane. However, the manner in which the nozzles 101 and 102 are coupled to the head 100 is not limited thereto. For example, the second nozzle 102 may be coupled to the head 100 in a direction forming an acute angle with the first nozzle 101 with respect to the xy plane. As another example, the second nozzle 102 may be coupled to the head 100 in a direction that is symmetrical with the x-axis perpendicular to the z-axis from the first nozzle 101 with respect to the xy plane.

FIG. 6 shows the operation of the sprinkler 1 to which the plurality of nozzles 101 and 102 are applied. The head 100 may control the turning radius by adjusting the positions of the first adjusting member 51 and the second adjusting member 52. However, if only one nozzle is installed in the head 100, a dead space area where water is not sprayed regardless of the position of the angle adjusting members 51 and 52 will be generated.

According to the present embodiment, since the plurality of nozzles 101 and 102 are installed in the head 100, generation of such dead space can be minimized or eliminated. For example, if it is assumed that the second nozzle 102 is coupled to the head 100 in a direction perpendicular to the first nozzle 101 with respect to the xy plane, The dead space can be removed by adjusting the angle between the first adjusting member 51 and the second adjusting member 52 to 270 degrees or more.

As another example, assuming that the second nozzle 102 is coupled to the head 100 in a direction that is symmetrical with the x-axis perpendicular to the z-axis from the first nozzle 101 with respect to the xy plane, The dead space can be removed by adjusting the angle between the first adjusting member 51 and the second adjusting member 52 to 180 degrees or more based on the moving path of the engaging member 310. [ That is, the dead space can be removed by adjusting the angle between the first adjusting member 51 and the second adjusting member 52 according to the angle between the first nozzle 101 and the second nozzle 102 will be.

7 is a perspective view showing a structure of a head of a sprinkler according to another embodiment of the present invention.

Since the number of the nozzles 101, 102, and 103 provided in the head 150 varies only in the present embodiment, the description of the other components will be omitted.

As shown in FIG. 7, the head 150 of the sprinkler according to the present embodiment may be provided with three nozzles. For example, the nozzle 150 may be provided with a third nozzle 103 from the first nozzle 101 in a direction symmetrical with respect to the x-axis. That is, the third nozzle 103 is coupled to the head 150 in a direction perpendicular to the second nozzle 102 with respect to the xy plane. In other words, the third nozzle 103 is vertically disposed from the first nozzle 101 about a longitudinal axis (z-axis), and 180 degrees from the second nozzle 102 about the longitudinal axis And is disposed obliquely.

At this time, in order to remove a region where water is not sprayed through the nozzles 101, 102 and 103, the first adjusting member 51 and the second adjusting member 52 is preferably adjusted to 180 degrees or more.

In the present invention, the number of nozzles provided in the head is limited to two or three, but the number of the nozzles is not limited thereto. It is noted that the angle between the plurality of nozzles may vary depending on the location, environment, etc. of the sprinkler.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
