The above-described sprinkler for snowmelt in a multi-house type greenhouse / house is provided with a sprinkler provided between a ridge of greenhouses / houses arranged in parallel, and a pumping device. Since watering is performed simultaneously by water supply, the capacity of the pumping device for watering must be increased compared to the case of a single building type, and the motor for driving it must also have a large capacity. In addition, there is a problem that the facility cost is high and the installation place is required to be wide.

An object of the present invention is to solve the problem of the conventional water sprinkling apparatus for snow melting in a multi-building type greenhouse or house. It is an object of the present invention to provide a new means for reducing the capacities of a pumping device for watering and a motor for driving each device so that an effective snow melting process can be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the means of the present invention, a greenhouse or a house is arranged in such a manner that arch-shaped or gable-shaped roofs of the respective buildings are arranged side by side, as in the case of a normal multi-story type.
A large number of buildings are constructed in a row, and rain gutters are installed at the connection points of each building, where the roof material of the roof of each building is joined to form a valley. In each of the upper parts of the rain gutters, of the ridges arranged in multiples, the upper parts of the rain gutters provided respectively at the outer edges of the ridges located on the outer side in the arrangement direction are provided with watering devices, respectively. Water supply pipes are connected to these sprinklers, respectively, and the spouts of a pump device driven by a motor are connected to the water supply pipes. May be configured in the same manner as in the conventional water sprinkling device for melting snow in a multi-building greenhouse / house.

However, the water supply pipes connected to the water sprinklers arranged in series are provided with valves corresponding to the respective water sprinklers so that water can be supplied to the water sprinklers separately for each water sprinkler. Install multiple mechanisms. These valve mechanisms are configured as electric valves that are operated by an electromagnet or a motor so that they can be remotely operated.

These motor-operated valves are sequentially opened one by one by a timer circuit and a relay circuit incorporated in a separately provided control device, and one of the motor-operated valves is set at a desired time. When the valve closing operation is performed after a lapse of a predetermined time, the opening operation of the next electric valve is performed. After that, the valve closing operation is performed after the lapse of the predetermined time, and the opening of the next electric valve is performed. Control is performed so as to perform the valve operation, and thereby, a number of watering devices arranged side by side are controlled so as to sequentially perform the watering operation one by one.

At this time, the control device for controlling the motor-operated valves installed in multiple units is such that one of the roofs of the greenhouses / houses constructed in parallel is openable and closable, and a greenhouse sensor is provided. In the case where the lifting and lowering operation mechanism driven by the drive motor by the operation of the above is linked, and when the temperature rises, this movable one roof is opened, the movable one roof is A control circuit for controlling the operation of each motor-operated valve may be incorporated in a control box in which a control device for a drive motor to be opened and closed is incorporated.

In addition, a pump device for connecting a water discharge port to a water supply pipe to perform a water spraying operation on a water spray device is provided with a predetermined water spray device among one of the water spray devices installed in parallel in a plurality. It is possible to select a pump device having a capacity enough to perform the sprinkling operation, and it is not necessary to use a large-capacity pump device capable of performing the sprinkling operation in all of the multiple sprinkling devices at once.

The same applies to the motor for driving the pump device, and a motor having a small capacity corresponding to the capacity of the pump device may be selected.

The motor is operated by turning on / off a drive circuit of the motor by a switch provided in the above-described control box or a control box provided separately, so that snow melting at the time of snowfall is required. The operation may be performed at an appropriate time, but at that time, the operation may be controlled so as to operate intermittently after a fixed time.

At this time, each of the sprinklers to be installed in parallel and in multiple units is sequentially switched by opening and closing operation of the electric valves arranged in parallel in multiple units, and the water sprinkling operation is performed for a predetermined time. In the case of such control, it is necessary to stop this motor in a series of steps from the first sprinkler to the last sprinkler in the multiple sprinklers. Set the time passed,
When the motor is operated again after a predetermined interval, the sprinkling operation of the multiple sprinklers is started again from the first sprinkler in the parallel order.
