Detailed Description

The utility model provides a wind-force unloads power component, includes wind-force conversion mechanism and unloads the power subassembly, it includes fixed plate 14 and movable plate 13 to unload the power subassembly, be equipped with on the fixed plate 14 and let out mouth 15, movable plate 13 shutoff sets up let out mouth 15 one side to with fixed plate 14 sliding connection can open let out mouth 15, wind-force conversion mechanism is connected with movable plate 13 transmission, through converting the wind-force of fixed plate windward side into kinetic energy in order to promote movable plate 13 and slide for fixed plate 14, opens let out mouth 15.

The wind force of the windward side refers to the wind blown toward the fixed plate 14 as shown by the wind direction arrow 18 in fig. 5 or the wind blown toward the fixed plate 14 while forming a certain angle with the fixed plate 14 and decomposing the wind in the direction of the wind direction arrow 18. The above-mentioned spillway 15 can set up one also can set up a plurality of, when spillway 15 only sets up one, movable plate 13 can adopt whole board in order to shutoff spillway 15 on the fixed plate 14, when spillway 15 is provided with a plurality of, movable plate 13 can adopt whole board in order to shutoff spillway 15 on the fixed plate 14, also can set up spillway I151 on whole board, the spillway I151 on the movable plate staggers with the spillway 15 on the fixed plate 14 each other in order to shutoff spillway on the fixed plate, under the effect of wind, make movable plate 13 slide relatively with the fixed plate 14, and then control spillway 15 is opened and is leaked the wind pressure release. The wind power conversion mechanism can specifically adopt a common structure capable of converting wind power into kinetic energy, such as a fan blade conversion structure, a flywheel wind power conversion structure (specific reference can be made to the application number of CN200580049391.5, flywheel wind power conversion device) and the like.

Through the use of the mutual cooperation of wind power conversion mechanism and unloading power subassembly, as shown by wind direction arrow 18 in fig. 5, when the windward side of fixed plate 14 has wind, wind power conversion mechanism converts wind power into power according to wind power size, through giving the power transmission to unloading power subassembly, if wind power is big enough, then drive unloading power subassembly and carry out the air leakage pressure release, if wind power is less, then keep the original state, and then make this wind power unloading power component can utilize wind power to adjust self state voluntarily, reach wind little hinder people and hinder dust, wind big opening unloading power's purpose. When no wind or no wind is generated, the movable plate 13 seals the leakage opening 15 on the fixed plate 14 to form a plate shape for wind prevention and dust prevention; when wind is large, the wind power conversion mechanism rotates to convert wind power into kinetic energy, and the movable plate 13 is pushed to slide relative to the fixed plate 14, so that the leakage opening 15 on the fixed plate 14 is gradually opened, and an opening is formed for air leakage and pressure relief. The process of air leakage and pressure relief does not need to be operated manually, so that the labor cost is saved.

In order to save the labor cost of the position of the movable plate 13 after the manual homing operation, the wind power unloading member can be automatically reset after the operation. The wind power unloading member also comprises a reset piece which can control the movable plate 13 to re-block the leakage opening 15.

The reset piece can be specifically provided with a reset spring, a torsion spring or a connecting rod type reset mechanism and the like, and the installation position of the reset piece is selected and installed according to the structure adopted in practice. If the return spring is adopted, one end of the return spring can be arranged on the fixed plate, and the other end of the return spring is arranged on the movable plate; when the wind force is reduced and the force is not required to be removed, the moving plate is driven to return to the original position due to the self-restorability of the spring; if the reset connecting rod is adopted, a proper position is selected for installation according to the actual installation condition.

When the wind force gradually decreases, the wind power conversion mechanism stops running, and at the moment, the reset piece resets the movable plate 13 due to self elasticity, and the leakage opening 15 on the fixed plate 14 is plugged again to form a plate shape for wind prevention and dust prevention.
