This invention discloses a wall-type windshield power generation device including a plurality of shells, a plurality of generating blade assemblies and a power collecting system. The plurality of shells are connected to form a wall structure, each of the shells is provided with a plurality of transverse air inlets, an accommodating chamber, an air outlet and a channel which are communicated with each other, and the transverse air inlets face towards a windward side. The plurality of generating blade assemblies are respectively arranged in the plurality of accommodating chambers and rotate from the corresponding transverse air inlets to the air outlets, and the power collecting system is connected with the plurality of generating blade assemblies. Strong wind at the windward side pushes the generating blade assemblies to rotate from the transverse air inlets to the air outlet when being blown from the transverse air inlets to the accommodating chambers, therefore, not only the strong wind is counteracted, but also wind energy is converted into electric energy in a rotation process. Therefore, the scheme can achieve aims of shielding wind and generating power； in addition, flexible increment or reduction can be realized due to a modular design.本發明係一種牆式擋風發電裝置，其包括複數殼體、複數個發電葉片組件及一集電系統。複數殼體連結成牆結構，每一殼體具有相互連通的複數橫向進氣口、一容室、一出氣口及一通道，橫向進氣口朝向迎風側。複數個發電葉片組件分別設於複數個容室內，並從相對應之橫向進氣口朝出氣口的方向轉動，集電系統連結複數個發電葉片組件。當迎風側之強風從橫向進氣口吹入容室，強風推動發電葉片組件從橫向進氣口朝該出氣口的方向轉動，除用以抵消強風外，並在轉動過程中，將風能轉換為電能。故，本案達到可擋風也可發電及模組化之設計可以彈性增減。
