Description

Photovoltaic greenhouse capable of effectively guiding water and ventilating

Technical Field

The utility model relates to an agricultural facility field belongs to plant and uses big-arch shelter structure, especially a photovoltaic big-arch shelter that can effectively guide water ventilation.

Background

With the application and popularization of new energy industries, photovoltaic power generation technology is rapidly developed. The photovoltaic greenhouse is characterized in that a solar cell panel is arranged at the top of a common greenhouse, so that the requirement of plant growth can be met, and photoelectric conversion can be realized. One part of electric energy generated by photovoltaic power generation can be supplied to the photovoltaic greenhouse system, and the other part of electric energy can be output to a power grid. The photovoltaic power generation assembly utilizes the top space of a common greenhouse, does not occupy the ground and does not change the land use property, so that the land resource can be effectively saved. Meanwhile, the photovoltaic greenhouse is built on the original agricultural farmland, so that the development of modern agricultural projects is facilitated, and the economic income of farmers is directly increased.

At present, the photovoltaic greenhouse is simple in structure, and a large-area photovoltaic module such as a solar cell panel is generally paved on the whole top of the greenhouse. The photovoltaic big-arch shelter is installed in outdoor environment, and when the rainfall appeared, the rainwater then can descend the photovoltaic module position at the big-arch shelter top. The rainwater is light polluted water, organic pollutants in water are few, dissolved oxygen is close to saturation, the rainwater can be used for irrigation of the greenhouse through simple treatment and collection, the current photovoltaic greenhouse does not effectively solve the coupling problem of photovoltaic power generation and rainwater collection, a large amount of rainwater resources are not fully utilized, and the rainwater can only be discharged out of order.

Meanwhile, the photovoltaic equipment is installed at the top of the greenhouse, so that the external surface of the greenhouse is not continuous and smooth, and the discharged rainwater can be accumulated in a gap formed by the photovoltaic equipment. In the use, although these rainwater generally can not cause the influence to photovoltaic module, nevertheless can infiltrate in the big-arch shelter gradually after long-time the accumulation, and then cause the temperature and the humidity change in the big-arch shelter. The top of the greenhouse is the highest part of the position in the greenhouse, the shielding objects around the greenhouse are few of the positions with the best ventilation effect, but because the photovoltaic module is paved on the top of the greenhouse, the window is difficult to open at the top, natural air circulation cannot be realized, the auxiliary ventilation device can be installed at other lower positions, and waste is caused invisibly.

The utility model has the advantages that:

the utility model discloses in, the shed roof adopts two segmentation structures, divide into the last shed roof that is parallel to each other and shed roof down, and the shed roof interval sets up with shed roof down along outside last shed roof, forms the difference in height in vertical direction. Compared with an integrated shed roof structure, the air outlet window is designed on the basis that the layout area of the solar cell panel is not reduced, and natural ventilation is achieved. In addition, the two-section structure realizes the respective drainage of the upper shed roof and the lower shed roof, the water is not easy to remain, the drainage effect is better, and the laid water collecting ditch can guide rainwater to the water collecting tank in order, so that the rainwater can be recycled conveniently. The structure of rainwater sensor and motor control transom opening and closing can in time perceive the weather change of big-arch shelter position, and operating personnel only need control opening and shutting of motor and turn to can realize the switching of transom, and is easy and simple to handle, need not artifical manual switch transom. In addition, the device retains the expansion technology, and the automatic opening and closing or remote control of the transom window can be realized only by installing the device for controlling the motor.
