Solar self-powered intelligent exhaust device of greenhouse

Abstract

The invention discloses a solar self-powered intelligent exhaust device of a greenhouse. The device comprises a box, wherein the box is through in the front and rear directions; a louver is arranged on the rear end surface of the box; an exhaust fan is arranged on the front part of the interior of the box; solar panels are arranged on the surface of the top of the box; a temperature and humidity sensor and a carbon dioxide sensor are arranged on the side surface of the rear part of the box; a control circuit board and an accumulator are arranged in the box; the exhaust fan, the solar panels, the temperature and humidity sensor, the carbon dioxide sensor and the control circuit board are all electrically connected with the accumulator; the circuit board can control turn-on and turn-off of the exhaust fan according to data detected by the temperature and humidity sensor and the carbon dioxide sensor. According to the device, automatic air exhausting can be conducted according to detectedenvironment parameters in the greenhouse, so that the requirements for manpower are effectively reduced, the device can not only provide a better growing environment for fruits and vegetables to improve the yields and the quality of the fruits and the vegetables, but also provide a better temperature and humidity environment for growers, and diseases brought by the environment can be reduced to acertain extent.

Description

technical field [0001] The invention relates to an exhaust device for a greenhouse, in particular to an intelligent exhaust device for a solar self-powered greenhouse. Background technique [0002] Plastic greenhouses are widely used in rural areas. Many people use greenhouses to grow fruits and vegetables in winter, in order to supply some fruits and vegetables in advance to obtain higher profits, such as strawberries. Greenhouses can advance the cultivation period of strawberries to 2-3 months. During the winter holiday and Chinese New Year period, the flow of people is large, so higher profits can be obtained. However, there are the following problems in the process of cultivating and planting plants in plastic greenhouses: one is because the photosynthesis, respiration, and transpiration of plants in the growth process will produce carbon dioxide and water, so someone needs to let the air out regularly, especially at the end of the harvest. During the critical period, s...

Problems solved by technology

However, there are the following problems in the process of cultivating and planting plants in plastic greenhouses: one is because the photosynthesis, respiration, and transpiration of plants in the growth process will produce carbon dioxide and water, so someone needs to let the air out regularly, especially at the end of the harvest. During the critical period, someone needs to be guarded in the shed almost all the time; second, due to the temperature and humidity difference inside and outside the shed, the temperature inside the shed is high and the humidity is high, and the temperature outside the shed is low and the humidity is low in winter. People often suffer from diseases such as rheumatism and rheumatoid

[0003] According to the search, there have been technologies related to intelligent exhaust devices. For example, Chinese patent No. 2013202912440 discloses "a new type of exhaust heat system for vegetable greenhouses". The interior of the greenhouse provides heat, but it has higher requirements on the structure of the greenhouse, and is more suitable for greenhouses with higher construction requirements, not suitable for plastic greenhouses with slightly different structures in various regions

Another example is "an intelligent exhaust system" disclosed in Chinese patent application number 2017210402999. This device is controlled by a single-chip microcomputer and can accurately and stably measure the temperature, humidity and air quality indicators in the indoor environment. However, it is not powered by solar energy, so it is not suitable for difficult In a plastic greenhouse with a stable external power supply
