Claims (1)
受光手段で受光した光量を予め入力されている基
準光量と比較して回転刃の破損、摩耗等を検出す
るブレード監視装置において、 投光された光が回転刃で焦点を結ぶように投光
手段と回転刃との間に投光用レンズを設けると共
に、受光手段に入射する光を受光手段に集光させ
るように受光手段と回転刃との間に受光用レンズ
を設けたことを特徴とするブレード監視装置。[Scope of claim for utility model registration] Light projecting means and light receiving means are arranged on both sides of the rotary blade,
In a blade monitoring device that detects damage, wear, etc. of a rotary blade by comparing the amount of light received by the light receiving means with a reference light amount inputted in advance, the light emitting means is configured to focus the emitted light on the rotary blade. A light projecting lens is provided between the light receiving means and the rotary blade, and a light receiving lens is provided between the light receiving means and the rotary blade so as to condense the light incident on the light receiving means onto the light receiving means. Blade monitoring device.
