Description

[Detailed description of the invention] The present invention relates to a water sprinkler controller equipped with a solar battery, and is designed to electrically control the water supply valve installed in the watering equipment, for example, in golf course watering equipment, agricultural irrigation prevention and control watering equipment, etc. It is something.

Conventional water controllers with solar cells of this type have a solar cell that converts solar heat into electricity installed at the top of a post erected on the ground, and the control panel that controls the water supply valve and the storage battery that stores the electricity generated by the solar cell are the same. It was provided in a case, and the case was located below the upper end of the post, and was provided in the middle of the post. The storage battery is bulky, which makes the case large. Since the solar cells and the case are installed outdoors in a place exposed to sunlight, the case that houses the control panel with the heat-sensitive IC control circuit must be insulated throughout to suppress the rise in internal heat. It had to be a structure. However, as mentioned above, the case is large and there is a problem in that it is expensive to make the entire case a heat insulating structure. In addition, in order to stably erect a post that supports a heavy object such as the storage battery on the ground, the post must be made thicker and the lower end of the post must be fixed using anchor concrete, which also increases costs. We were connected.

The present invention was devised to address such problems, and the purpose is to provide a water sprinkler controller with a solar battery at a low cost.

Hereinafter, the present invention will be explained based on drawings showing an example of implementation. In the figure, reference numeral 1 denotes a concrete box for storing a storage battery, which is buried in the ground 2 so that its upper surface is visible, and a storage battery 3 is stored in this box 1. Reference numeral 4 designates a top cover that is placed over the top of the box 1, and is fixed to the box 1 by tightening a hook bolt 6 using a U-shaped band 5. Reference numeral 7 denotes a cylindrical post whose lower end is fitted into a short cylindrical portion 8 protruding from the center of the upper surface of the upper lid 4 and is erected, and the lower end of the post 7 and the cylindrical portion 8 are fixed with a tightening screw 9. Reference numeral 10 denotes a control box having a substantially right triangular side surface and a substantially rectangular plan view, which houses a control panel 11 with an IC control circuit that controls the water supply valve of a watering equipment for a golf course, for example. A short cylindrical portion 12 protrudes, and this cylindrical portion 12 is externally fitted onto the upper end of the post 7, and the cylindrical portion 12 and the upper end of the post 7 are fixed by a tightening screw 13. The operating section 11a on the upper surface of the control panel 11 is disposed so as to be flush with the inclined upper surface of the box 10.
A top lid 14 is attached to the box 10 so as to cover it from above.
is attached via two left and right links 15, 15 so as to be openable and closable. That is, the upper cover 14 can be in an inclined closed state (shown by the solid line in FIG. 2) in which it covers the operating section 11a from above, or in an open state in which it is moved toward the upper end located at the rear end of the box 10 so that the operating section 11a can be operated. (shown by the two-dot chain line in Figure 2). One end of each link 15 is pivotally supported on the rear end inner surface of the left and right side plates 16 of the box 10, and the other end is supported on the left and right side plates 17 of the upper lid 14.
The rotation of the link 15 with respect to the box 10 is stopped when the link 15 stands up as shown by the two-dot chain line in FIG.
The top lid 14 is placed on top of box 1.
0 can be maintained in a slanted open state at the upper end of the rear end. The upper lid 14 is configured to have a depth that gradually increases from the front end to the rear end so that the upper lid 14 can be stably maintained in the slanted open state shown by the two-dot chain line in FIG. There is.
18 is a solar cell provided on the upper surface of the upper lid 14;
When the top cover 14 is closed as shown by the solid line in FIG. 2, solar heat is absorbed, converted into electricity, and stored in the storage battery 3. The inclination angle of the solar cell 18 with the upper lid 14 closed is set to be the optimum angle for heat collection. Reference numeral 19 denotes a heat insulating material attached to the inner surface of the top lid 14, and when the top lid 14 is closed, the bottom surface of this heat insulating material 19 comes into contact with the top surface of the box 10 and the operating section 11a. By the way, although not shown, a heat insulating material is installed on the inner surface of the box 10 except for the top surface, and between the solar cell 18 and the storage battery 3, between the control panel 11 and the storage battery 3, and between the control panel 11. and the water supply valve are electrically connected. This electrical connection wiring is passed through the post 7.

The operation of the solar battery-equipped watering controller configured as described above will be described. With the upper lid 14 closed, the solar battery 18 absorbs solar heat, converts it into electricity, and stores it in the storage battery 3. When opening the water supply valve for water sprinkling, the water supply valve opens automatically at a time reserved in advance using the operation section 11a of the control panel 11 to perform water sprinkling.
The watering operation is also completed by automatically closing the water supply valve at the scheduled time. The water supply valve may be opened and closed by opening the top cover 14 and operating the operating portion 11a every time water is sprinkled.

The water sprinkler controller with solar cells of the present invention can be implemented as described above, and the following effects can be obtained.

That is, the storage battery is stored in a box buried in the ground to support the post, and the control panel is separated from the storage battery and stored in a control box installed at the top of the post, so the control box is small. Although the top cover and solar battery are installed on the top of the control box, the weight of the control box is lighter compared to the conventional case where a storage battery is installed inside the box that houses the control panel, and the control box can be mounted with a small diameter post. Support can be provided. Further, since the control box is small, less heat insulating material is needed to protect the control panel inside the control box, and the control box can be provided at low cost. Furthermore, the upper lid is in an inclined state when covering the inclined upper surface of the control box, so that the solar cells on the upper surface of the upper lid have a high heat collecting effect, and the operation section of the control panel can be operated only when the upper lid is open. It is easy to operate because it is operated on the sloping upper surface of the machine.

In addition, as in the embodiment shown in the drawings, by making the storage battery storage box, post, and control box separately, it is possible to transport the storage battery without bulk.
It can also be easily assembled on site.
