A mesh blade cloth, paraglider and windmill

Abstract

Provided are blade-like grid cloth and a manufacturing method therefor, and a paraglider and a windmill made of same, falling within the field of laminar products. The blade-like grid cloth comprises an upper thread rope layer (201) and a lower thread rope layer (202), wherein the lower thread rope layer (202) comprises a plurality of first thread ropes which are arranged side by side; the upper thread rope layer comprises a plurality of second thread ropes; the plurality of second thread ropes are crosswise laid at an upper side of the plurality of first thread ropes; and one end of each blade (102) is adhered between the first thread ropes and the second thread ropes, and the other end of each blade is a movable end and is located below the first thread ropes. The blade-like grid cloth can be applied to a plurality of fields, such as paraglider fabric, windmill blade surfaces capable of rotating horizontally and aquatic sport shoes, etc. The paraglider and the windmill respectively comprise the blade-like grid cloth. The paraglider can fly without power and can also be driven to fly by an engine. The technical solution provides a blade-like grid cloth through which fluid can only pass in one direction, so that a relatively great pressure difference can be formed between two sides of the blade-like grid cloth, and the pressure difference can effectively provide a raising force with a simple principle.

Description

technical field

[0001] The invention relates to the field of layered products, in particular to a mesh blade cloth, a parachute and a windmill. Background technique

[0002] Existing blades are divided into two types, blades with leakage holes and blades without leakage holes, both of which cannot form a large pressure difference between the upper and lower sides of the blade. Contents of the invention

[0003] The purpose of the present invention is to provide a mesh blade cloth, which can form a larger pressure difference on both sides to provide a larger lifting force.

[0004] The object of the present invention is to provide a flying parachute capable of obtaining greater lifting force.

[0005] The purpose of the present invention is to provide a windmill with better rotation efficiency.

[0006] The present invention is achieved like this:

[0007] The mesh blade cloth provided by the present invention includes an upper layer wire rope and a lower layer wire rope...
