Embodiment 1

[0052] Embodiment 1 Turntable electrostatic generator

[0053] The first embodiment is a rotating disc type electrostatic generator, image 3 It shows its schematic structure diagram, such as image 3 As shown, it includes two turntables, that is, a first turntable 1 and a second turntable 2, both of which are in the shape of a pie and have the same outer diameter. Also, the two turntables coincide with each other in a center-aligned manner,

[0054] The first turntable 1 and the second turntable 2 can rotate relatively around their central axis (rotate simultaneously, or one is stationary and the other rotates), and relative sliding can occur on their contact surfaces during rotation. The contact surfaces of the two turntables both include friction layers, shown as a first friction layer 11 and a second friction layer 21 in the figure. The surfaces of the first friction layer 11 and the second friction layer 21 are respectively provided with friction material regions 101 a...

[0076] Embodiment two: wind energy generator

[0077] The second embodiment is a wind energy invention machine constructed by using the rotary disk type electrostatic generator, which can be used to collect wind energy and convert it into electrical energy. Figure 9 A schematic block diagram of the wind energy generator is shown. Such as Figure 9 As shown, the generator utilizes the image 3 The rotating disk type electrostatic generator of the first embodiment shown, and the generator includes a windmill 3, the windmill 3 is fixedly connected with a rotating shaft 4; and, the rotating disk 1 is fixed to a fixing device 5, and the rotating shaft 4 is fixedly connected to the center position of the turntable 2. Thus, when the windmill 3 rotates under the drive of the external wind, it can drive the turntable 2 to rotate relative to the turntable 1 through the rotation shaft, thereby generating an alternating induced potential between the turntable 1 and the turntable 2 to ge...

[0079] Embodiment 3: brake energy storage device

[0080] Embodiment 3 is an implementation manner in which the rotary disc type electrostatic generator is applied to a vehicle, such as a brake system of an automobile. During the braking process of the brake pads of existing automobiles, the mechanical energy transformed by the huge frictional force is mostly emitted in the form of heat energy, and has not been utilized. If the turntable electrostatic power generation device of the present invention can be loaded into the brake parts of the brake system, and the mechanical energy of the wheel rotation during the collection is collected, the energy efficiency of the car will be greatly improved, and it will be beneficial to the further development of the composite car and the clean energy car. has great significance.

[0081] Figure 11 A schematic structural diagram of the brake energy storage device of the third embodiment is shown. Such as Figure 11 As shown, the turnta...

Abstract

The invention discloses a rotary type electrostatic generating device comprising a first component and a second component. At least one friction material zone is respectively arranged at the contact surface of each component; and friction materials with different friction electrode sequences are respectively arranged in the two friction material zones. The friction material of the first component is attached to a first conducting element; the friction material of the second component is attached to a second conducting element; and the two conducting elements are connected by an external circuit. The first component rotates relatively to the second component, so that sliding friction is generated at the contact surfaces of the two components and thus periodic superposition and separation occur at at least one portion of the two friction material zones. According to the invention, the rotary type electrostatic generating device has characteristics of small size, low rotation resistance, high energy conversion efficiency, and easy packaging and integration and can be widely applied to fields like power generation, energy conservation, rotating speed measurement and the like.
