Description

Technical Field

[0001] This invention relates to the field of window screens, and in particular to a power-generating window screen. Background Technology

[0002] Window screens are one of the few building materials that possess flexibility and a certain degree of elasticity. Utilizing the charge transfer caused by the sliding friction between the warp and weft threads of the window screen under the influence of airflow, sound, and building vibrations, they can be used for purposes such as charging and energy storage, display illumination, and high-pressure mosquito killing, thus possessing practical value.

[0003] Currently, there are few devices and equipment for generating electricity from window screens. Photovoltaic power generation, wind power generation, and concentrated solar power generation are not suitable for window screens due to their limited size and space. The emergence of triboelectric power generation technology has opened up new possibilities for power generation from window screens. Scientifically speaking, triboelectric charging should be called contact charging, which utilizes the mechanical energy from surrounding sounds, walking, water flow, and gentle breezes to generate electricity. Currently, there are four power generation modes: wind-induced, sliding, single-electrode, and charged-body induction.

[0004] Achieving triboelectric power generation from window screens presents certain challenges. The small contact area of ​​the window screen results in low effective triboelectric charge. How to promptly dissipate the charge and achieve effective contact separation are all challenges faced by triboelectric power generation window screens. It is necessary to solve these problems through invention and innovation. Summary of the Invention

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] A power-generating window screen includes a multi-layer mesh, a converter 1, and a capacitor 2. The mesh includes an outer current-collecting layer 3, an outer current-releasing layer 4, an inner current-releasing layer 5, and an inner current-collecting layer 6, which are distributed sequentially from the outside to the inside. The outer current-collecting layer 3 and the inner current-collecting layer 6 are electrically connected to the converter 1, and the converter 1 is electrically connected to the capacitor 2 through a power generation circuit.

[0031] The outer current collector layer 3 and the inner current collector layer 6 are made of copper fiber, stainless steel fiber, or carbon fiber.

[0032] The outer ionizing layer 4 and the inner ionizing layer 5 are made of materials including polytetrafluoroethylene, polyethylene terephthalate, polydimethylsiloxane, and polyamide.

[0033] The inner ionizing layer 5 is sprayed onto the surface of the inner current collector layer 6 and then hot-pressed to set its shape.

[0034] The external ionizing layer 4 is sprayed onto the surface of the external current collecting layer 3 and then hot-pressed to set its shape.

[0035] In the circuit,

[0036] The outer collector layer is connected to the positive terminal of diode D1 and the negative terminal of diode D2;

[0037] The inner collector layer is connected to the positive terminal of diode D3 and the negative terminal of diode D4;

[0038] The negative terminals of diode D1 and D3 are connected to pin 1 of resistor R3 and pin 6 of chip U1.

[0039] Pin 2 of chip U1 is connected to the other pin of resistor R3;

[0040] Pin 3 of chip U1 is connected to the negative terminal of capacitor C2 and the negative terminal of USB-9V power supply;

[0041] Pin 5 of chip U1 is connected to pin 1 of resistor R2;

[0042] Pin 8 of chip U1 is connected to pin 1 of resistor R1;

[0043] Pin 9 of chip U1 is connected to the positive terminal of capacitor C1;

[0044] The other leg of resistor R2 is connected to the positive terminal of capacitor C2 and the positive terminal of LED D5;

[0045] The negative terminal of LED D5 is connected to the positive terminal of the USB-9V power supply;

[0046] The positive terminal of diode D2, the positive terminal of diode D4, the other terminal of resistor R1, the negative terminal of capacitor C1, and pin 10 of chip U1 are connected to reference ground.

[0047] The chip U1 is a constant current source driver chip with model number HA22006P;

[0048] The diodes D1-D4 are preferably of model 1N4004.

[0049] The outer and inner collector layers are connected to the positive and negative terminals of the converter, respectively. The converter converts unstable alternating current into stable direct current and connects it to a capacitor through the output terminal. Both the outer and inner collector layers are composed of conductive mesh as collector electrodes, which can be woven meshes of copper fiber, stainless steel fiber, carbon fiber, etc. The outer and inner ionizing layers are both made of polymer nanofiber materials, which are two polymer pairs that readily gain and lose electrons. For example, the outer and inner ionizing layers can be polytetrafluoroethylene and polyethylene terephthalate, or polydimethylsiloxane and polyamide, etc.

[0050] When encapsulating the outer and inner current collector layers, they must be separated by an insulating material to prevent them from contacting each other, otherwise a short circuit will occur. At the same time, the outer and inner current collector layers must be given different degrees of relaxation during the encapsulation process to ensure that the inner and outer current collector layers are in different swing amplitudes under the action of airflow, vibration, etc., thereby increasing the contact and friction opportunities of the inner and outer current-generating layers covering them and improving power generation efficiency.

[0051] Manufacturing steps:

[0052] The outer current-collecting layer mesh is woven with metal wire or graphite wire, and then polytetrafluoroethylene nanofibers are sprayed onto the mesh to form an outer current-emitting layer, which is then hot-pressed for shaping.

[0053] The inner current collector layer is woven with metal wire or graphite wire, and then the inner current release layer of polyethylene terephthalate nanofibers is sprayed onto the yarn and hot-pressed for shaping.

[0054] The outer and inner current-collecting layers of the spray-spun nanofiber mesh are composited in the order of outer current-collecting layer, outer current-releasing layer, inner current-releasing layer, and inner current-collecting layer; and then encapsulated with insulating hot melt adhesive and cut according to different window screen sizes.

[0055] Connect the encapsulated window screen, the small converter, and the capacitor.

[0056] After installation, when the door is opened or the wind blows, the inner and outer window screens will move relative to each other, generating friction and producing electricity through friction.

[0057] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
