Abstract

The application relates to a wind discharge apparatus, pertains to the wind-proof technique field, especially to a solar reflecting mirror wind discharge apparatus. The wind discharge apparatus is a wind discharge apparatus with locating, wind-discharging, shock-absorbing and anti-jamming functions which is formed by that the wind discharge apparatus is connected with the panel through a wind discharge machine or a vibration absorber. When the wind-engaging body encounters a destructive wind force, the panel of the wind-engaging body rotates, firstly fast then slow, to discharge the wind, thereby avoiding the strong wind from destroying the wind-engaging body; when the panel is rotating and switching-on, the wind force decreases or the wind force turns suddenly, the panel will slow down or switching-off firstly fast then slow, to avoid the larger impact force to the frame produced by the panel, thereby avoiding the destroy to panel made of frangibility or easy for plastic deformation materials, or avoiding larger noise. The wind discharge apparatus can be widely used in solar reflecting mirror, satellite receiving antenna, radar antennas, advertisement boards and the like.

Description

technical field [0001] The present application relates to the technical field of wind protection, in particular to a wind unloading device for a solar reflector. Background technique [0002] Due to the high cost of solar energy equipment at present, the popularization of solar energy utilization is slow. For example, using cheap glass instead of stainless steel and other metals as solar reflectors will greatly reduce the cost of solar energy equipment. When the wind is strong, it is easy to shatter the glass reflector and even hurt people; therefore, the reflector must have the function of unloading the wind, that is, when encountering destructive wind force, the mirror lens can rotate with the wind direction, so that the reflector is perpendicular to the wind direction. The wind-receiving area becomes smaller, which minimizes the wind force on the reflector, and removes the wind force, thereby avoiding damage to the reflector by strong wind. This wind unloading function c...

Problems solved by technology

Its concept is very good, but because 1, the working position of its lens is determined by the contact of the limit body and the frame connected by the spring force. If the spring force is small, the small wind force can blow the lens, thereby affecting the lens. If the spring force is large, the lens rotates at a certain angle when encountering destructive wind force. At this time, if the wind force suddenly turns, the lens will quickly reset and close under the action of spring force or spring force and wind force, causing the lens to be damaged. The frame produces a large impact force. If the lens is made of fragile materials such as glass, the large impact force will cause the lens to break

2. Since the lens limiter is one-way rotating to unload the wind, if the lens cannot rotate when encountering reverse destructive wind force, if the lens is relatively flat (the curvature of the lens is small from the figure), the entire condenser will be affected. strong winds, and even damage

Mr. Jia Yongzhuang's Chinese patent application No. 93231206.3 discloses a wind-resistant advertising billboard. The key points of the wind-resistant scheme are: the upper part of the movable board is connected to the frame, and the bottom has touch beads, rubber pads, and magnets for positioning, and the movable board rotates in the wind , so as to remove the wind force, and rely on gravity to reset after the wind stops; its structure is simple, but there is no explanation on how to position the bumper beads, rubber pads, and magnets. In place; if it is too small, it will not play a positioning role; if the magnet surface is parallel to the surface of the movable plate, it will cause one-way rotation to unload the wind. If it encounters reverse destructive wind, the movable plate cannot rotate; if the magnet surface is perpendicular to the surface of the movable plate It will cause the magnetic force to fail to locate
