Problems solved by technology

Japanese patent JP2000-261057 discloses a solar cell as a roof material for planting greenhouses, but it does not involve the problem that the general greenhouse environment is dusty, and the surface of solar cells is easy to accumulate dust, which affects power generation efficiency.
In addition, the Chinese patent ZL200620001877.3 "Greenhouse Roof Automatic Cleaning Machine" discloses an electric cleaning machine that can automatically walk on the roof of a large-scale multi-span greenhouse through switch control to clean the glass roof. More complicated, not suitable for large-scale popularization in rural areas

Embodiment 1

[0029] See figure 1 and figure 2 , the solar photovoltaic greenhouse includes a main frame 1, a ventilation device and a thermal insulation device, and the solar cell assembly 2 and the transparent material 7 modules are installed to form a roof. The roof is connected to the main frame 1 by a plurality of components, and the cleaning solar cell assembly 2, the eaves are provided with drainage grooves 4, and the electric energy generated by the solar cells is drawn out through wire slots 8 by electric wires. Inside the solar photovoltaic greenhouse, the positive and negative electrode wires of the solar cell module 2 are converging and drawn out, and are connected to the battery 9 and the control device 10 through the wire slot 8 and the main frame 1 to supply power to the load. The storage battery 9 and the control device 10 have expansion interfaces, and the expansion interfaces are used to connect AC / DC electric equipment.

[0030] The main frame 1 adopts the existing gre...

Embodiment 2

[0035] The specific implementation mode of this embodiment is the same as that of embodiment 1.

[0036] The roof material used in this embodiment is an amorphous silicon solar cell module 2' and a transparent material glass 7. Such as figure 1 and figure 2 As shown, the solar cell roof of the double-top truss structure, or gable beam, is connected by two "herringbone" gable peaks, that is, the roof is formed by connecting two double-slope roofs. A cleaning device for cleaning the solar cell module 2 is arranged on each spire. This cleaning device is a circular tube that is provided with a water outlet hole on the side wall by a fixed strip 6 on the band. One end of this circular tube is connected to the water nozzle 13, and the other end is blocked. As shown in Figure 7, the section of the upper fixing bar 6 is in the shape of a "Q", the lower part of the "Q" shape is an inverted "T" shape, and the bottom edge of the inverted "T" shape is in the shape of a broken line, as...

Embodiment 3

[0039] In Beijing, a double-spire greenhouse with a width of 8 meters, a length of 40 meters, and a height of 3 meters is built in Beijing. The inclination angle of the roof of the greenhouse is 35 degrees. Amorphous silicon battery modules are installed on the two sides facing south. The specific implementation method is the same as in Example 1. I won't repeat them here.

[0040] Such as Figure 9 As shown, the glass of the amorphous silicon solar panel adopts self-cleaning glass, and a sliding glass window is installed facing the north, which can generate 40-60 kWh of electricity per day on average annually. The middle part of the double spire is supported by support beams 14, and the two ends of the support beams 14 are fixed on the columns of the main frame 1 with a width of 8 meters, such as figure 2 As shown, a sunshade net can be added inside, built on the support beam 14, and the support beam 14 can place the pipe of the sprinkler system, which can be a hollow suppo...

Abstract

The invention discloses a solar energy photovoltaic greenhouse. Solar module is used for constructing a photovoltaic matrix for providing power to the greenhouse. The solar energy photovoltaic greenhouse with the solar module comprises a main frame, a ventilation device and an attemperator and is characterized in that the greenhouse also comprises a roof with a single-top or multi-top truss structure which is built by solar cells and transparent material. A vault is provided with a cleaning device. A bus-line is introduced by an electrode to a bus to be connected with indoor electro-load. The solar energy photovoltaic greenhouse has the beneficial effect that the solar module is utilized to the utmost. Especially, amorphous silicon cells which are used as the photovoltaic building material of the agricultural greenhouse have the advantages of easy sealing and large breadth. With low cost, the building material can be used for the photovoltaic power generation of roofs and walls. The solar energy photovoltaic greenhouse uses an original greenhouse frame and can be popularized easily. The cleaning device can maintain the clean surface of the solar cells, improve the power generating efficiency and prolong the service life of the cells.

Description

technical field [0001] The invention relates to a solar photovoltaic greenhouse, which uses solar battery components to construct a photovoltaic matrix, which is used as an agricultural greenhouse for light transmission and power supply. Background technique [0002] The emergence of greenhouses has greatly enriched people's lives, making people's diets no longer restricted by the four seasons, and also brought great economic benefits to people who use greenhouses, achieving a harmonious win-win situation. At the same time, the types and functions of greenhouses It is also constantly expanding and extending. There are many types of greenhouses. There are various types of greenhouses according to the purpose of use, building form, degree of insulation and building materials. The types range from the original plastic greenhouse to the current modern intelligent sun room. , the function also has everything from a single planting to the current ecological leisure, especially as ...
