Solar roof ventilating device and method of zero energy consumption unattended power plant

Abstract

The invention provides a solar roof ventilating device of a zero energy consumption unattended power plant. The solar roof ventilating device consists of a ventilator and a solar photovoltaic driving device. At least one group of valve plates and a motor connected with the valve plates are arranged in the ventilator; and the motor is driven by the solar photovoltaic driving device. The solar photovoltaic driving device comprises a solar photovoltaic panel, the solar photovoltaic panel is connected in series with a storage battery, and the storage battery is connected with an intelligent controller and a motor, wherein the input end of the intelligent controller is connected with a temperature sensor, and the output end of the intelligent controller is connected with the motor. According to the solar roof ventilating device disclosed by the invention, a solar photovoltaic generation technology is applied to the roof ventilator for the first time, so that a novel energy source, namely solar energy, is used for supplying electric power to all electric components of the roof ventilator, and zero manual energy consumption is realized by avoiding access to a public power grid. The solar photovoltaic driving device is integrally designed. A user only needs to replace a former manual power distribution system by the solar photovoltaic driving device, and then the solar roof ventilating device can control drive operation by using the novel energy source to the former roof ventilator; and the construction complexity is reduced.

Description

technical field [0001] The invention belongs to the technical field of roof ventilators and new energy sources, and in particular relates to a zero-energy unattended solar roof ventilator for power plants. Background technique [0002] In order to eliminate harmful dust and gas pollutants generated during the production process, eliminate waste heat and humidity, and meet the hygiene requirements of the personnel in the work area, the power plant workshop usually needs to adopt comprehensive ventilation, in which the roof is made of indoor heat and external heat pressure and outdoor wind pressure. The ventilator is a main form of controlling the overall ventilation operation, which saves the power consumption of the fan and its operating cost compared with the way of controlling the ventilation volume by relying on a large fan. However, the motor used for the control valve plate of the existing roof ventilator still needs to be equipped with external power transmission and d...

Problems solved by technology

However, this method has the following major disadvantages or reliability problems

[0005] (1) In summer, when the solar radiation is large during the day, the luminous flux in the factory building may be too high to affect human vision, and the radiation heat gain entering the room is also the largest, which will greatly increase the cooling load of indoor ventilation. In principle, it needs to be further improved. The amount of ventilation is used to compensate, which increases the initial investment and operating costs of the ventilation system

[0006] (2) After sunset in winter, especially on sunny days, the surface of the building envelope and the surface of equipment can form a radiation heat effect with the outdoor sky, which further lowers the indoor temperature and increases the discomfort of personnel. will increase its heat load

[0007] (3) There are potential reliability problems of aging or breaking of the light-transmitting board

When tempered glass and other glass products are used, due to the impact of external disturbances such as cold and heat, wind and rain, and hail, there is a potential risk of damage to the production line and its supporting equipment or even endangering personal safety due to rupture, such as the use of glass curtain walls or atriums similar to high-end office buildings When using high-end glass products such as skylights, although the security is higher, the price is too high to be economical in industrial plants

If high-strength plastic products are used, it may cause accelerated aging and deformation due to long-term external disturbance impacts such as ultraviolet light, and affect its light transmittance
