Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a wind-patrolling blind sail, including several parts of circular track 11, rotating platform 12, blind sail, energy memory and arresting gear.

The circular rail 11 is a main body of the present invention, and is fixed on the ground or on the horizontal surface of the place of use when installed. A plurality of guide wheels 41 are installed on the bottom surface of the rotating platform 12, grooves 42 matched with the circular track 11 are formed on the surface, in contact with the circular track 11, of the guide wheels 41, and when the rotating platform 12 works, the guide wheels 41 roll on the circular track 11. The guide wheels 41 are in circular array on the bottom surface of the rotary platform 12 by taking the axis of the rotary platform 12 as a reference, namely, the distance between the adjacent guide wheels 41 is equal to the included angle formed by the axis of the rotary platform 12.

The louver sail is composed of a bottom plate 31 fixed on the rotary platform 12, a louver 32 fixed on the bottom plate 31 and a top plate 33 fixed at the other end of the louver 32, wherein the bottom plate 31 and the top plate 33 are respectively fixed at two ends of the louver 32. There are a plurality of tripes 32 on every bottom plate 31 to the straight-line distance between the axis of every tripe 32 and the axis of rotary platform 12 equals, and like this the wind pressure is used in tripe 32 back, and the work of every tripe 32 is unanimous, can make the undulant decline of rotational speed of rotary platform 12, can enough reduce mechanical shock, also can make the utility model discloses the operation is more stable.

The louver 32 is formed by two parts, a first blade 321 and a second blade 322, which are no longer in the same plane.

One pull cord 6 is attached to the top plate 33, and here, the rotation direction of the top plate 33 is defined as the front of the top plate 33 and the opposite direction to the front is defined as the rear. The other end of the pull cord 6 is fixedly connected to the rotatable platform 12, and the fixed connection point is located behind the top plate 33.

The energy storage device is composed of a support 21, a rotating shaft 22, a transmission wheel 23 and an energy storage flywheel 24, wherein the support 21 is installed on the outer side of the circular track 11, and the rotating shaft 22 is installed on the support 21 and can rotate freely. The transmission wheel 23 and the energy storage flywheel 24 respectively rotate at two ends of the shaft 22, wherein the transmission wheel 23 is in contact with the rotating platform 12 and is responsible for transmitting energy to the energy storage flywheel 24. The energy storage flywheel 24 serves as an energy storage element, and its inertia must be greater than that of the driving wheel 23, so that energy can be output when the wind speed is reduced.

The braking device is composed of a friction ring 71 fixedly arranged on the rotating platform 12, a braking bracket 72 arranged outside the rotating platform 12, push rods 73 symmetrically arranged on the braking bracket 72 and a friction plate 74 arranged on the push rods 73 and matched with the friction ring 71. During braking, the push rod 73 pushes the friction plate 74 to contact the friction ring 71, so as to convert kinetic energy into heat energy and reduce the rotation speed of the rotating platform 12.

The number of the braking devices is more than two and the braking devices act simultaneously around the axis circular array of the rotating platform 12, so that on one hand, the stress of the friction ring 71 is more uniform, the inclination caused by overlarge stress of the uniform distribution is avoided, and on the other hand, when the friction plates 74 work simultaneously, the abrasion is also reduced.

The push rod 73 used in the brake device is a pneumatic push rod, a hydraulic push rod or a screw rod, wherein the pneumatic push rod and the hydraulic push rod need to be provided with corresponding compressors and hydraulic stations, and the screw rod needs to be driven to rotate by a motor.

The inner side surface and/or the outer side surface of the rotating platform 12 are/is provided with teeth 5, and the teeth 5 are connected with external power generation equipment and are responsible for transmitting the kinetic energy of the rotating platform 12 to the power generation equipment.

Referring to fig. 3, the intersection of the dotted lines is located on the axis of the rotary platform 12, i.e. the distance between each louver 32 and the axis of the rotary platform 12 is equal, so that the moment of each louver 32 on the rotary platform 12 is also equal, and the fluctuation of the rotation speed of the rotary platform 12 can be reduced as much as possible.

The implementation principle of the embodiment is as follows:

in operation, wind acts on the louvers 32 to apply a pushing force to the louvers 32, and the louvers 32 begin to move forward when subjected to the pushing force. When the louver 32 moves forward, the rotating platform 12 is driven by the bottom plate 31 to rotate on the circular track 11, and the louver 32 also rotates along with the rotation of the rotating platform 12.

When the rotary platform 12 rotates, the transmission wheel 23 in contact with the rotary platform also starts to rotate. When the transmission wheel 23 rotates, the energy storage flywheel 24 is driven to rotate through the rotating shaft 22.

When the rotary platform 12 rotates, the teeth 5 drive the power generation equipment connected with the rotary platform to work, and the power generation equipment converts kinetic energy into electric energy.

When the wind speed is reduced, the rotating speed of the rotating platform 12 is reduced, and at the moment, the energy storage flywheel 24 continues to rotate under the action of inertia, so that the stored energy is transferred to the rotating platform 12, and the reduction amplitude of the rotating speed of the rotating platform 12 is reduced.

When the rotation speed of the rotary platform 12 is too high, the push rod 73 is actuated to push the friction plate 74 to move in a direction close to the friction ring 71 and contact with the friction ring 71, the kinetic energy of the friction ring 71 is converted into heat energy, and the rotation speed is reduced. Since the friction ring 71 is connected to the rotary platform 12, the rotational speed of the rotary platform 12 is also reduced.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
