As shown in fig. 1, the present embodiment provides a wind uncovering prevention early warning system 100, which is suitable for collecting and monitoring wind uncovering conditions of roof panels of various large-span spatial structures such as railway station platforms, airports, stadiums, exhibition centers and the like, such as metal roof panels, and transmitting collected data out, so that the wind uncovering damage condition of the roof panels is obtained by users/maintenance personnel, and the wind uncovering damage of the roof panels forms an early warning to provide a basis for timely maintenance.
The wind uncovering prevention early warning system 100 comprises a roof panel wind uncovering data acquisition device 10, a data transmission device 20 and a terminal 30. The roof panel wind uncovering data acquisition device 10 is used for acquiring wind uncovering data of the roof panel, and the data transmission device 20 is used for transmitting the wind uncovering data to the terminal 30. Therefore, the user can obtain the wind uncovering condition of the high roof at any time through the terminal 30.
The wind uncovering prevention early warning system 100 comprises a plurality of roof panel wind uncovering data acquisition devices 10 so as to acquire wind uncovering data of a plurality of positions of a roof panel 10 a. Through the sectional roof panel wind uncovering data acquisition device 10, the wind uncovering position of the roof panel can be accurately identified, the procedure of examining the wind uncovering position again after an maintainer goes up the roof is omitted, and the maintenance at a fixed point is facilitated for the maintainer.
As described above, the data transmission device 20 may be connected to the terminal 30 by a cable through wired transmission according to the field environment, or may be connected to the terminal 30 by wireless communication through wireless transmission. The terminal 30 may be a mobile terminal or a fixed terminal 30. In this embodiment, the data transmission device 20 includes a wireless communication module, and the terminal 30 is a mobile terminal, such as a mobile phone, a tablet computer, a notebook computer, and the like. The terminal 30, as a human-computer interaction device, provides a visual early warning interface for receiving the wind uncovering data, identifying and judging the wind uncovering data, and displaying the wind uncovering data or the early warning condition. Therefore, the terminal 30 has functions of storage, recognition, judgment, early warning, and visualization.

Therefore, early warning is carried out through the terminal 30, so that maintenance personnel can maintain in time, and the damaged roof panels can be reconnected and fixed in time before larger-area damage is generated.
Referring to fig. 2 to 3, the roof panel wind uncovering data acquisition device 10 includes an induction member 1, a flexible cable 2, a restraint member 3 and a reversing member 4. The sensing member 1 is used for sensing the lifting condition of the roof panel 10 a. The flexible inhaul cable 2 is stretched on the roof panel 10a, and two ends of the flexible inhaul cable are respectively connected with the roof panel 10a and the induction part 1. Restraining member 3 is attached to roof panel 10a for slidably retaining flexible cable 2 on roof panel 10a along a predetermined path. The reversing piece 4 is connected to the end side of the roof panel 10a or the support 10b of the roof panel 10a and is used for supporting the flexible cable 2 so that the sensing piece 1 forms suspension tension on the flexible cable 2.
When the roof panel 10a is under the action of a small wind load, the connection between the roof panel 10a and the support 10b is not damaged, the acting force of the roof panel 10 a/the restraint part 3 on the flexible inhaul cable 2 can be ignored, the tension direction of the flexible inhaul cable 2 is changed through the reversing part 4, then the flexible inhaul cable 2 is connected with the induction part 1, and the tension of the flexible inhaul cable 2 along the roof panel 10a is converted into the suspension tension along the vertical direction. When the roof panel 10a is under the action of large and large wind load or long-term wind load, the joint of the roof panel 10a and the support 10b is damaged, which will cause the roof panel 10a to generate upward acting force on the flexible inhaul cable 2 through the restraint part 3, thereby causing the stress condition of the whole flexible inhaul cable 2 to change, further causing the wind uncovering data of the roof panel 10a induced by the induction part 1 to generate large change, and the wind uncovering data at the moment reaches the early warning threshold value.
The sensor 1 is an acceleration sensor for sensing acceleration in the direction of suspension, i.e. in the vertical direction, as described above. Under the condition that wind load is certain, the more serious the damage is, the larger the acting force of the restraint piece 3 on the flexible inhaul cable 2 is, the larger the acceleration fluctuation condition is, and according to the characteristic, the acceleration data fluctuation condition can be measured through the acceleration sensor to identify the wind uncovering damage condition of the roof panel 10 a. The lifting of the roof panel 10a is reflected by the vertical acceleration of the inductor 1 suspended thereon.
In other embodiments, the sensing element 1 may also be a displacement sensor, and the lifting amplitude of the roof panel 10a is detected by sensing the displacement of the end of the flexible cable 2, and the position of the sensing element 1 is used as the wind uncovering data of the roof panel 10 a.
The flexible cable 2 is a kind of tension transmission member for changing the acceleration of the sensing member 1 by pulling the sensing member 1. The flexible inhaul cable 2 can be a steel wire rope which is a slender material with strong tensile capacity and a certain shearing capacity, so that the safety and reliability of the system in the operation early warning process are ensured. Meanwhile, the steel wire rope has certain deformability, and after the wind load is acted, the balance state of the roof panel wind uncovering data acquisition device 10 is kept through deformation of the steel wire, so that the safety of the roof panel wind uncovering data acquisition device 10 is ensured.
The roof panel wind uncovering data acquisition device 10 further comprises a fixing piece 5, and the flexible inhaul cable 2 is connected to the roof panel 10a through the fixing piece 5. The fixing member 5 is attached to the roof panel 10a, and is used to fix one end of the flexible cable 2 to the roof panel 10 a. In this embodiment, the fixing member 5 is block-shaped, may be an iron block, and may be fixed to the roof panel 10a by welding or bolt connection. Of course, the structure of the fixing member 5 may be other structures, and any connecting structure for connecting and fixing the flexible inhaul cable 2 to the roof panel 10a falls into the selection category of the fixing member 5.
The flexible inhaul cable 2 is connected to one side of the roof panel 10a, and the sensing piece 1 is suspended on the other side of the roof panel 10 a. Therefore, the flexible inhaul cable 2 is tensioned on the roof panel 10a along the preset direction, the tensioning degree of the flexible inhaul cable 2 on the roof panel 10a is increased as much as possible, the sensitivity of the sensing piece 1 to the lifting amplitude of the roof panel 10a is increased, and the roof panel wind uncovering data acquisition device 10 can acquire the wind uncovering data of the roof panel 10a more sensitively.
The constraining member 3 serves to constrain the tension path of the flexible cable 2 on the roof panel 10a and to effectively transmit the lifting of the roof panel 10a to the flexible cable 2. The restraint piece 3 is a circular ring, the locking edge of the roof panel 10a is provided with the circular ring, namely the joint of the roof panel 10a and the support 10b is provided with the circular ring, the flexible inhaul cable 2 penetrates through the circular ring, and the restraint, the guide and the force transmission effect are formed on the flexible inhaul cable 2 through the circular ring. The distribution path of the restraint member 3 is a tensioning path of the flexible cable 2 on the roof panel 10a, and in order to ensure that the lifting motion of the roof panel 10a is smoothly transmitted to the flexible cable 2, the flexible cable 2 should be tensioned straightly along the roof panel 10a, and the projection of the axis of the restraint member 3 on the horizontal plane falls on the same straight line. Of course, the structure of the restraint member 3 may be other structures, and any structure for movably holding the flexible cable 2 on the roof panel 10a falls into the category of the restraint member 3.
Further, the restraining element 3 is an iron ring, and is fixed to the seaming end of the roof panel 10a by welding, and if a fixture is provided at the seaming position of the roof panel 10a, the iron ring may be welded to the fixture.
The reversing piece 4 converts the pulling force (usually horizontal pulling force) of the flexible inhaul cable 2 along the roof panel 10a into vertical pulling force, namely, the gravity direction of the sensing piece 1 is consistent with the pulling force direction of the flexible inhaul cable 2 at the rear section.
The reversing element 4 can be a fixed pulley and is fixed on the end part of the roof panel 10a or the support 10b according to field conditions on the premise of ensuring the direction of the flexible inhaul cable 2 to be changed. The flexible inhaul cable 2 is wound on the fixed pulley, and the sliding friction between the flexible inhaul cable 2 and the reversing piece 4 is changed into rolling friction through the structure of the fixed pulley. Therefore, the flexible stretching movement is smoother, the stretching stress of the flexible inhaul cable 2 is reduced, and meanwhile the sensitivity of the flexible inhaul cable 2 in the transmission of the lifting condition of the roof panel 10a is improved. The reversing element 4 can be fixed on the roof panel 10a or the support 10b by welding, bolting or the like.
It should be noted that the suspension length of the sensing element 1 should not be too long, that is, the length of the vertical suspension section of the flexible cable 2 should be as short as possible, so as to ensure that the influence of wind on the vertical acceleration of the sensing element 1 (the vertical acceleration generated by the swinging of the sensing element 1) is reduced as much as possible.
In this embodiment, the data acquisition device 10 is uncovered to roof boarding wind still includes and suspends 6 in midair, and response 1 is connected on flexible cable 2 through suspending 6 in midair, suspends 6 in midair and provides the tensile force for flexible cable 2 for tighten flexible cable 2, so that flexible cable 2 can produce the removal correspondingly along with the lift of roof boarding 10a, guarantees the sensitivity that flexible cable 2 lifted the condition transmission to the roofing. The gravity of the suspension piece 6 is larger than or equal to the tension force required by the flexible inhaul cable 2, and meanwhile, the suspension piece 6 has certain gravity and can also reduce the influence of wind on the acceleration sensed by the sensing piece 1. However, in order to ensure the safety of suspension, the weight of the suspending element 6 should not be too large.
Meanwhile, the suspension member 6 stretches the flexible cable 2 by suspending, and has a certain effect of inhibiting wind uplift of the roof panel 10 a.
It is understood that the suspension member 6 can be omitted if the sensing member 1 or the sensing member assembly can provide a sufficient tension for the flexible cable 2.
Further, on the upper surface of hanging in the midair 6 was located to response piece 1, hung in the midair 6 and be the cuboid cubic, can be the iron plate, flexible cable 2 and the upper surface four corners of hanging in the midair 6 are articulated. From this guarantee to suspend piece 6 in midair the state all the time, have the higher upper surface of levelness, for response 1 provides stable sensing face, guarantee that response 1 can accurately detect the acceleration of suspending the upward movement of piece 6. The sensing member 1 may be an existing acceleration sensor, and a data transmission device 20, such as a wireless communication module, may be disposed on the suspension member 6, and the wireless communication module transmits data sensed by the acceleration sensor to the terminal 30.
The induction part assembly can be provided with a storage battery, the induction part 1 and the wireless communication module are powered by the visual line of the storage battery, and the storage battery can ensure the electric quantity of the storage battery through periodic replacement; also can suspend in the midair 6 surfaces and set up solar cell panel, utilize solar cell panel to charge to the battery, guarantee that the battery can last for induction part 1 power supply.
Above, the roof boarding wind uncovering data acquisition device 10 should be arranged at the weak position of roof boarding 10a wind uncovering damage, such as: the eaves gutter junction of the roof panels 10a, the roof overhanging position or the longitudinal roof end, etc. In these positions, the flexible cables 2 are tensioned from the inside to the edge, and the flexible cables 2 can be tensioned to cross one or more roof panels 10a, and the sensing element 1 is suspended at the edge by the suspension element 6, so that the wind uncovering condition of the roof panels 10a at the position is sensed.
