Description
Technical Field
The utility model relates to a aerogenerator becomes oar system field, specific set of paddle equipment that becomes oar system that says so relates to in this field.
Background
Electric power is an indispensable form of energy in daily production and life. The traditional thermal power generation not only consumes a large amount of fossil resources, but also can discharge a large amount of greenhouse gases; nuclear power generation is extremely dangerous although it does not emit greenhouse gases, and once an accident occurs, it causes irreversible damage to the environment, so that clean energy represented by wind power generation is being vigorously developed in recent years in various countries. At present, the wind wheel of a mainstream wind driven generator adopts a form of adding a blade to a hub, and in order to ensure constant-speed rotation of the wind wheel, the windward angle of each blade of a fan needs to be adjusted in real time through a variable pitch system. However, no 400V power supply is provided in the installation stage of the fan, the variable pitch system cannot work, and the blade angle needs to be adjusted by using the blade assembling equipment independently, so that the hub can be conveniently hoisted.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a paddle system group paddle equipment that can adjust paddle angle alone is provided.
In order to solve the technical problem, the utility model discloses a following technical scheme:
in a group blade apparatus of a pitch system, the improvement comprising: the equipment comprises a cabinet body, a power grid voltage monitoring module electrically connected with an external power supply is installed in the cabinet body, a 24V switching power supply and a variable pitch driver are electrically connected with the power grid voltage monitoring module through a contactor, the 24V switching power supply supplies power for an indicator lamp on a panel of the cabinet body, and the variable pitch driver is controlled by a key on the panel of the cabinet body and can be electrically connected with a motor outside the cabinet body.
Furthermore, the bottom of the cabinet body is provided with a pulley, and the top of the cabinet body is provided with a handle.
Further, the external power source is a diesel generator.
Further, the variable-pitch drive can be connected with and controlled by a manual operation box outside the cabinet body.
The utility model has the advantages that:
the utility model discloses a group's paddle equipment of oar system becomes, small, light in weight, convenient to carry can be in fan installation phase very convenient carry out the independent control to the paddle angle.

fig. 2 is a schematic view of the internal structure of the cabinet of the paddle assembly device disclosed in embodiment 1 of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Embodiment 1, as shown in fig. 1-2, this embodiment discloses a paddle assembly device of a pitch system, where the device includes a cabinet 1, a grid voltage monitoring module 3 electrically connected to an external power supply 2 is installed in the cabinet, a 24V switching power supply 4 and a pitch driver 5 electrically connected to the grid voltage monitoring module through a contactor, the 24V switching power supply supplies power to an indicator lamp 6 on a panel of the cabinet, and the pitch driver is controlled by a key 7 on the panel of the cabinet and can be electrically connected to a motor 8 outside the cabinet.
In this embodiment, the cabinet 1 is provided with a pulley 11 at the bottom and a handle 12 at the top. The external power source is a diesel generator. The variable-pitch driver can also be connected with and controlled by a manual operation box outside the cabinet body.
The power grid voltage monitoring module can monitor the voltage of an external power supply and cut off power supply under the condition of voltage fluctuation so as to protect the safety of the variable pitch drive. The variable pitch driver can carry out open-loop control on the motor so as to adjust the angle of the blade.
