Abstract

A synchronous rotation opening-closing mechanism for wind shields comprises the following components: a frame, wind shields, upper rotatable parts, lower rotatable parts and a synchronous driving part. The wind shields are separately equipped in each pane of the frame with equal distance through the upper rotatable parts and the lower rotatable parts. The wind shields are rotatable relatively to the frame. All wind shields are driven by the synchronous driving component for simultaneously rotating. When the synchronous rotation opening-closing mechanism for wind shields is equipped to the periphery of a cooling tower, as the wind shields are equipped on the frame with a rotatable mode, the wind shields are rotatable relatively to the frame. When the temperature in winter is low, all the wind shields are caused to rotate to a closed state through the synchronous driving part; and when the temperature increases, the wind shields are caused to rotate into an open ventilation state. The synchronous rotation opening-closing mechanism can freely adjust the opening and closing state of the wind shields according to the temperature value of outer circumstance for ensuring that the cooling tower can operate normally and efficiently at any season.

Description

Synchronous rotation on-off mechanism of wind boards

Technical field

The utility model relates to the defroster that keeps out the wind of power plant's cooling tower.

Background technology

At northern frore area, to hyperbolic natural-draft cooling tower the anti-ice facility of hanging must be set, otherwise, cooling tower will cause serious extension ice phenomenon, cause packing in the cooling tower, carriage is dragged and part trickle Structure Beam-column causes and seriously freezes molten dew muscle, make normally safe operation of cooling tower, more can not effectively control the water temperature in the cooling tower.For a long time, people adopt the method for building windbreak around cooling tower to solve antifreeze problem usually, and described windbreak is made up of framework and deep bead, and deep bead is hung solid on framework by the mode of artificial suspension.In arriving winter, need build the high-altitude installing rack, solid on framework by manually the deep bead block-by-block being hung, perhaps install by high-altitude operation vehicle; When after winter, again deep bead block-by-block from the framework is removed, and collection takes good care of, be convenient to utilize again the coming year.Because the quantity of deep bead is many, volume is big, heavier, the artificial suspension of annual deep bead, the workload of excision are very big, not only labour intensity is big, holding time is many, and artificial high-altitude application is also dangerous, is easily damaged in deep bead, the excision process solid at frequent extension simultaneously, maintenance cost height, result of use are difficult to guarantee.

Along with the fast development of China's electric utility, large cooling column is on the increase, and the air inlet height of cooling tower also increases to some extent, and the length of deep bead and weight also increase thereupon, and this brings bigger difficulty to the anti-ice facility of hanging of cooling tower, and operating cost will further increase.Do not hang ice winter in order to ensure cooling tower, under the prerequisite of the antifreezing effect that guarantees anti-extension ice facility, avoid repeating to hang admittedly and extracing of deep bead, reduce operating cost, eliminate the deep bead high-altitude and hang the hidden danger that exists in solid and the excision operation, make the anti-ice facility of hanging of cooling tower can play the anti-antifreeze effect of ice of hanging in the winter time, can guarantee good performance of ventilating again in other season, the applicant has successfully developed a kind of automatic starting and closing type anti-freezing device of wind screen of cooling tower, and it has solved the problems referred to above well.Wherein synchronous rotation on-off mechanism of wind boards is its core content.
