Detailed Description
The following describes in detail a self-adaptive typhoon-preventing reinforcement system and a reinforcement method for a box-type house according to the present invention with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent in conjunction with the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Example one
As shown in fig. 1 to 4, the present embodiment provides an adaptive typhoon-prevention reinforcement system for a boxed house, which includes a guy cable 10, a tension sensor 20, an anchoring device 30, a guide collar 40, a tension adjusting device 50, an anemometer 60 and a controller 70.
The anemometer 60 is disposed on the top of the box-type room to measure the wind speed V.
The guide lantern ring 40 is arranged at a guy cable corner and a guy cable limiting position on the box-type house, and the guy cable 10 needs to bypass the top of the box-type house, so that the guide lantern ring 40 needs to be arranged at the top of the box-type house, and the direction of the guy cable 10 is changed. In addition, when the straight-line section guy cable 10 is long, the guy cable is easy to swing, which is not beneficial to the safety of the box-type house, and a guide lantern ring 40 is required to be added to limit the guy cable 10.
The tension adjusting device 50 comprises a bidirectional electric roller 51 and a roller bracket 52; the roller bracket 52 is fixed to a support structure for supporting the bidirectional motorized roller 51. Typically, the support structure may be a hardened ground or concrete column, with the roller bracket 52 secured by expansion bolts 53. For example, the cable 10 is pulled when the bidirectional motor-driven drum 51 rotates forward, and the cable 10 is unloaded when the bidirectional motor-driven drum 51 rotates backward.
One end of the inhaul cable 10 is arranged at an anchoring point through an anchoring device 30, for example, the anchoring device 30 comprises an anchor body 31 and an anchor head 32, the anchor body 31 is arranged in the supporting structure, the anchor head 32 is fixed on the anchor body 31, a lantern ring is arranged on the anchor head 32, and the end part of the inhaul cable 10 or the end part of the tension sensor 20 is fixedly connected with the lantern ring.
The cable 10 is provided with a tension sensor 20, and the tension sensor 20 is used for measuring the tension F of the cable 10. The other end of the guy cable 10 passes through the guide collar 40 on the box-type house and then is wound on the bidirectional electric roller 51.
The controller 70 is used for collecting the wind speed V measured by the anemometer 60 and the tension F measured by the tension sensor 20. The controller 70 is provided with a corresponding relation between the wind speed and the pulling force of the pulling cable, and the controller 70 is used for controlling the rotation mode of the bidirectional electric roller 51 so that the pulling force F of the pulling cable meets the requirement of the wind speed. For example, the controller 70 is provided with a corresponding relationship between the wind speed and the pulling force of the pulling cable, specifically, the wind speed VmCorresponding to the pulling force of the cable [ F ]1 m，F2 m]Where m is a natural number, e.g. 10 th wind is V1Corresponding to the pull of the cable [ F ]1 1，F2 1](ii) a When the wind speed V measured by the anemometer 60 reaches 10 levels, if the tension F e [ F ] measured by the tension sensor 201 1，F2 1]When the pulling force of the inhaul cable meets the requirement, the bidirectional electric roller 51 rotates to be in a stop state; if the tension F measured by the tension sensor 20 is larger than F2 1When the pulling force of the pulling cable is too large, the controller 70 controls the bidirectional electric roller 51 to rotate to reduce the pulling force of the pulling cable, and when F is less than or equal to F2 1The controller 70 controls the bidirectional motorized pulley 51 to stop rotating; if the tension F measured by the tension sensor 20 is less than F1 1If the tension of the cable is too small, the controller 70 controls the bidirectional electric roller 51 to rotate to increase the tension of the cable, and F is greater than or equal to F1 1The controller 70 controls the bidirectional motorized pulley 51 to stop rotating.
Another example is that grade 9 wind is V2Corresponding to the pull of the cable [ F ]1 2，F2 2]，F2 2＜F1 1When the wind power is changed from 10-grade wind to 9-grade wind, the original F belongs to [ F ]1 1，F2 1]Thus, F > F2 2The controller 70 controls the bidirectional electric roller 51 to rotate to reduce the tension of the cable when F≤F2 2The controller 70 controls the bidirectional electric roller 51 to stop rotating, so that the problem that the windproof stay cable 10 is fatigue in use due to the fact that the stay cable 10 is in an overload tensioning state for a long time is solved, the replacement frequency of the stay cable is reduced, and the problem of saving maintenance cost is solved. When the wind power is changed from 9-grade wind to 10-grade wind, the original F belongs to [ F ∈ [ ]1 2，F2 2]Thus, F < F1 1The controller 70 controls the bidirectional electric roller 51 to rotate to increase the tension of the stay cable, when F is more than or equal to F1 1The controller 70 controls the bidirectional electric roller 51 to stop rotating, and the guy cable stops tensioning and self-locking, so that the guy cable tension and the wind speed are automatically matched after the wind speed is increased.
