Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkler apparatus for automatically sprinkling water over a wide range, and more particularly to a sprinkler apparatus for sprinkling water on turf such as a golf course or a school ground.

[0002]

2. Description of the Related Art An impact-type sprinkler is relatively frequently used in a sprinkler apparatus for spraying water on a turf cloth such as a golf course or a school ground. The impact type sprinkler repels the swing arm against the spring force by the jet water from the nozzle rotatably supported by the support, and the repelled swing arm is released from the jet water and returns quickly by the spring force However, the nozzle collides with the nozzle and rotates the nozzle, and the rotation of the nozzle is less affected by sludge and dust in running water than the gear drive system or the cam drive system using a water wheel drive. However, the rotation speed of the nozzle may change due to a change in water pressure, and it is difficult to always secure the rotation speed of the nozzle to obtain an appropriate watering state. Therefore, a sprinkler using a motor (electric motor) as a nozzle rotation driving source is also used so that the nozzle can always be rotated at a predetermined speed. When an electric motor is used as the rotation drive source, a predetermined rotation state can always be ensured, and the durability of the device can be improved because there is no need to configure a collision mechanism.

[0003]

Further, by using a sprinkler using a motor, it is possible to obtain a good water spray state by appropriately setting the nozzle rotation angle and nozzle rotation speed. However, since such an operation state of each sprinkler is set by directly operating each sprinkler,
When the watering range is large and the interval between the sprinklers is wide, the setting operation is troublesome, and the operation takes a long time.

Accordingly, an object of the present invention is to provide a sprinkler device that uses a plurality of sprinklers using a motor and can easily set the operation state of each sprinkler.

[0005]

In order to achieve this object, a sprinkler device according to the present invention comprises a support, a nozzle rotatably supported by the support, and a motor for rotating the nozzle. A sprinkler device for disposing a plurality of sprinklers at appropriate positions and spraying water over a predetermined range, provided with a remote control unit capable of individually setting an operation state of each sprinkler.
By operating one remote operation unit, for example, an operation touch panel, the operation state of each sprinkler, for example, the rotation angle of the nozzle, watering time or the rotation speed of the nozzle is individually set. The setting of the rotation angle of the nozzle determines the watering range or watering shape of one sprinkler, and as a result, determines the watering range or watering shape of the entire sprinkler device, so that it can be set individually by the remote control unit. It is preferable that the sprinkler time and the rotation speed of the nozzle do not always need to be set individually, and each sprinkler always has the same time,
In some cases, they are configured to operate at the same rotation speed.
In this case too, the operating time of the sprinkler and the rotational speed itself should be adjustable.

In the case of using this sprinkler device, each sprinkler is arranged along the outer edge of a predetermined watering range and so as to surround the predetermined range, and the rotation angle of the nozzle of each sprinkler is controlled by the watering range. It is effective to set the area to be one section of the range so that the entire watering range formed by each watering area of the sprinkler coincides with or substantially coincides with the predetermined range. If the watering distance of each sprinkler is set to be sufficient, even if the sprinklers are arranged outside or on the outer edge of the predetermined range or slightly outside the outer edge, by appropriately setting the arrangement position, it is possible to set the sprinkler to a central position in a wide predetermined range. It is possible to prevent non-sprinkling points from occurring. By arranging each sprinkler along the outer edge of the predetermined watering range, it is possible to eliminate the situation where the use of the watering area is restricted due to the sprinkler being installed inside.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing the right side of the sprinkler used in the sprinkler device according to the present invention in cross section.

A cylinder 5 is rotatably arranged inside the support 3 of the sprinkler 1, and a water guide pipe 7 is arranged inside the cylinder 5 so as to be movable only in the vertical direction with respect to the cylinder 5. I have. A nozzle 9 is fixed to the upper end of the water guide pipe 7. Therefore, the nozzle 9 is rotatably supported by the support 3 via the cylinder 5 and the water guide pipe 7. Since the length of the portion of the water guide pipe 7 protruding from the cylinder 5 is short, and the support 3 extends to the upper end portion of the cylinder 5, the bending moment acting on the water guide pipe 7 and the cylinder 5 during jetting of flowing water is small. Therefore, a large braking force does not act on the rotation of the nozzle 9.

A motor case 11 is fixed to the support 3, and a stepping motor 13 is arranged in the motor case 11. The stepping motor 13 includes a worm wheel 15 mounted on the outer periphery of the cylinder 5.
In a state of engagement.

A vertically extending groove 17 is formed on the lower outer periphery of the water guide pipe 7, and a detent pin 19 attached to the lower end of the cylinder 5 is fitted into the groove 17. A compression coil spring 25 is disposed between a step 21 formed on the lower outer periphery of the cylinder 5 and a step 23 formed on the lower end outer periphery of the water guide pipe 7. Pressing.

Therefore, when flowing water enters from the inflow port 27 of the support 3, the lower end surface 29 is pushed by the flowing water, and the water guide pipe 7 rises against the spring force of the compression coil spring 25, and moves the nozzle 9 to the watering position. Push up. The flowing water flows out of the nozzle 9 through the inside of the water pipe 7. Stepping motor 1
When the cylinder 5 is rotated by 3, the water guide pipe 7, and hence the nozzle 9, is rotated integrally with the cylinder 5 by the action of the detent pin 19.

A proximity sensor 31 is provided at the upper end of the support 3 and detects the approach of a metal piece 35 provided at the tip of a support member 33 fixedly attached to the outer periphery of the upper end of the cylinder 5.

In the drawings, reference numeral 37 denotes a bearing, 39 denotes a dust seal, and 41 denotes a cushion member.

FIG. 2 is a side view showing the stepping motor 13. As shown in FIG.

The output shaft 43 of the stepping motor 13 is connected to a worm 47 via a gear 45, and the worm 47 meshes with the worm wheel 15.

FIG. 3 is a plan view showing the proximity sensor 31 part.

The nozzle 9 (see FIG. 1) and thus the cylinder 5 are rotated by a predetermined angle (for example, 90 ° or 180 °: see arrow X or Y) with the rotation position where the metal piece 35 is detected by the proximity sensor 31 as a starting position. I do.
When the cylinder 5 rotates by a predetermined angle, the stepping motor 13 (see FIG. 2) starts reverse rotation, and the nozzle 9 and the cylinder 5 rotate in the reverse direction to the starting position. If the number of rotations (the number of reciprocations) is set to be large, the nozzle 9 reciprocates between the starting position and the 90 ° position (or 180 ° position). The rotation angle of the nozzle 9 is detected by counting the pulse signal from the stepping motor 13, and the return of the nozzle 9 to the starting position is confirmed by the proximity sensor 31 detecting the metal piece 35. Specifically, the number of rotations of the nozzle 9 is set as one forward movement and one return movement. Therefore,
If the number of rotations is set to 3, the nozzle 9 stops operating on the side opposite to the start position, but in such a case, the stepping motor 13 automatically reverses and the nozzle 9 reaches the start position. It is configured to return.

FIG. 4 is a diagram conceptually showing a sprinkler device of the present invention.

The predetermined area A for spraying water has a wide rectangular shape, and the sprinkler 1 has two long sides B, B of the predetermined area A.
(Outer edge) and two on both short sides C, C (outer edge). The operation of each sprinkler 1 is separately and remotely controlled by the operation of a touch panel operation panel 49 (remote operation unit) via a sprinkler control panel 51, and a rotation for determining a nozzle rotation angle, a nozzle rotation speed, and a jetted water amount of each sprinkler 1. It is configured so that the number of times of angular reciprocation can be set. The nozzle rotation angle of the sprinkler 1 is set so that water is sprayed over the entire range from the outer edge located on one side of the sprinkler 1 to the outer edge located on the other side, and the water spraying range of each sprinkler 1 (shown by a broken line in the drawing) The compartments (see section) are designed to overlap with all or most other sprinklers 1 watering areas. The watering angle of each sprinkler 1 is displayed on the touch panel operation panel 49, and the operator can control the operation of each sprinkler 1 while checking the actual watering state. For example, if it is determined that the sprinkler 1 has already sufficiently watered the sprinkler 1 despite the long remaining operation time of the specific sprinkler 1, the operation of the sprinkler 1 is stopped regardless of the set number of reciprocations. be able to. Further, on the touch panel operation panel 49, an abnormality of the sprinkler device such as idling of the pump is displayed.

When the rotation angle of the nozzle 9 of each sprinkler 1 is set by the touch panel operation panel 49 (can be set every 1 ° within the range of 1 ° to 360 °), the nozzle 9 is moved to the starting position by the operation of the stepping motor 13. The rotation operation with respect to the set position (end position) is repeated for the set number of times. The nozzle 9 of each sprinkler 1 is 1
It rotates forward and reverse at an average speed of 4 ° to 6 ° per second, and intermittently operates at a narrow fixed angle during the forward and reverse rotations. The setting of the rotation time and the stop time in the operation of the nozzle 9 is arbitrary, but is preferably set to 0.5 seconds to 1.0 seconds.

In the figure, 53 is a water supply pump for supplying water to each sprinkler 1, and 55 is an electrode band.
