Description

Wind generating set operation supervisory equipment Technical Field The utility model relates to a detection equipment technology, in particular to operation monitoring equipment for a wind generating set. Background A vertical axis wind turbine, also known as a vertical axis wind turbine, is a type of wind turbine that is structurally different from a common Horizontal Axis Wind Turbine (HAWT). It is characterized in that the rotation axis of the wind wheel is vertical to the ground, but not parallel to the ground. The core structural characteristics of the vertical shaft wind generating set are as follows: the main shaft is vertical, and main components such as a generator, a gear box (if needed) and the like are usually positioned at the bottom of the tower or near the ground, so that the maintenance is relatively convenient. The blades are arranged in a radial manner around a vertical axis. Typical blade shapes are straight blades (H-type or Darrieus type), helical blades (reducing pulsating torque), or S-type (Savonius type). Referring to Chinese issued patent, publication number CN103089547B discloses a balanced vertical axis large-scale wind generating set. In the prior art including the above-mentioned patent, there is a general lack of effective monitoring technology for critical operating conditions of a counter-axis wind turbine generator set, in particular the rotational speed of the blades. Once the rotational speed of the blades exceeds a predetermined range, unit failure, structural damage and even safety accidents may be caused. Disclosure of utility model The utility model aims to provide wind generating set operation monitoring equipment so as to solve the defects in the prior art. In order to achieve the purpose, the utility model provides the technical scheme that the wind generating set operation monitoring equipment comprises a vertical shaft wind generating set, a wind generating set and a wind generating set control system, wherein the vertical shaft wind generating set comprises a blade bracket and a blade shaft lever assembled on the blade bracket, the blade bracket comprises mounting seats which are distributed in parallel along the vertical direction and have ports distributed adjacently, a rotating part fixedly connected with one end of the blade shaft lever is rotationally arranged on the mounting seats, and a protruding part is fixedly arranged on the rotating part; the mounting seat is connected with a sealing cover inserted on the blade shaft rod in a threaded manner, a shifting block is rotationally arranged on the inner side surface of the sealing cover, and the shifting block is in blocking and dismantling fit with the protruding part; The side surfaces of the adjacent sides of the shifting block and the sealing cover are respectively provided with an arch elastic metal reed. Preferably, a binding ring barrel is fixedly arranged in the mounting seat, and a rotary bearing is arranged in the binding ring barrel; An embedded ring is arranged on one side of the rotating part, and the inner ring of the rotary bearing is embedded in the embedded ring. Preferably, the end of the blade shaft is inserted into the inner ring of the rotating bearing. Preferably, an external thread part is fixedly arranged on one side of the sealing cover, and an internal thread is arranged on the external thread part and the inner wall of the mounting seat for threaded assembly. Preferably, the advancing end of the protruding portion is tapered along the rotation direction of the blade shaft. Preferably, a rubber pulley is rotatably arranged at the end part of the shifting block, and the rubber pulley is in rolling connection with the cone. Preferably, a V-shaped elastic plate is inserted between the sealing cover and the shifting block. Preferably, the V-shaped elastic plate is an elastic metal plate. In the technical scheme, the wind generating set operation monitoring equipment has the advantages that when the blade shaft rod rotates, the rotating part is driven to rotate synchronously, the protruding part is made to abut against the shifting block in the process, so that the shifting block is pushed by the protruding part to rotate, the two arch-shaped elastic metal reeds are in contact to realize electric connection so as to send out an electric signal, and when the protruding part passes over the shifting block, the shifting block is reset, and the two arch-shaped elastic metal reeds are separated again. The plurality of continuous electric signals are monitored to judge whether the rotation speed of the shaft lever of the current blade is abnormal or not so as to repair the damaged shaft lever in time Drawings In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings required for the embodiments will be briefly described below, and it is apparent that the drawings in the following description are only some embodi
