Description

Technical Field

[0001] This utility model relates to the field of deformation monitoring technology for inflatable membrane buildings, and specifically to an inflatable membrane building deformation monitoring system. Background Technology

[0002] Inflatable membrane structures, as a new type of large-span spatial structure, are widely used in stadiums, warehousing and logistics centers, industrial plants, and temporary emergency facilities due to their advantages such as light weight, short construction period, high space utilization, and controllable cost. Their core working principle relies on the pressure difference between the inside and outside of the membrane to maintain structural stability. However, during long-term use, inflatable membrane structures are susceptible to external environmental factors (such as strong winds, heavy rain, snow loads, and temperature changes) and internal operating conditions (such as air pressure fluctuations, equipment vibrations, and high personnel density), leading to deformation problems such as membrane bulging, dents, tears, or overall displacement. If deformation exceeds the safety threshold and is not monitored and warned of in a timely manner, it will not only affect the normal function of the building but may also cause major safety accidents such as membrane rupture and structural collapse. Therefore, real-time and accurate deformation monitoring of inflatable membrane structures is of crucial engineering significance.

[0003] A search revealed a utility model patent with publication number CN214121136U, which discloses an inflatable membrane structure deformation monitoring system. The system includes an inflatable membrane structure composed of an inflatable membrane retaining wall and an inflatable membrane body. It also includes at least two displacement sensors for monitoring the deformation of the inflatable membrane structure, a base, a pull wire, several annular hooks, a membrane top fixing block, and an inflatable membrane structure deformation monitoring device. The base is located on an inner wall of the inflatable membrane retaining wall. The membrane top fixing block is located on the inner top surface of the inflatable membrane body. The several annular hooks are evenly distributed on the inner top surface of the inflatable membrane body and located between the membrane top fixing block and the bottom end of the inner top surface of the inflatable membrane body. The at least two displacement sensors for monitoring the deformation of the inflatable membrane structure are mounted on the base. One end of the pull wire is connected to the displacement sensor, and the other end passes through the several annular hooks and is connected to the membrane top fixing block.

[0004] However, in the above-mentioned existing technology, the membrane top fixing block and the membrane material are fixedly connected during use. This makes it inconvenient to change the monitoring points when monitoring needs or building structure changes, thus affecting the deformation monitoring effect of the membrane material. Utility Model Content

[0005] This invention proposes an inflatable membrane structure deformation monitoring system to solve the problem of inconvenient adjustment of the detection position of the pull rope position sensor in the process of monitoring the deformation of the membrane material by pull rope displacement sensor in the prior art.

[0006] The technical solution of this utility model is as follows: An inflatable membrane building deformation monitoring system is used to detect the deformation of an air-supported membrane structure fixed to a building retaining wall. The system includes a mounting base, a first housing, a pull-rope displacement sensor, and an installation mechanism. The mounting base is fixed to the inner top wall of the air-supported membrane structure with adhesive. An installation groove is formed on the bottom side wall of the mounting base. The first housing is slidably disposed within the installation groove. The pull-rope displacement sensor is bolted to the building retaining wall. A hanging ring is fixedly disposed at the output end of the pull-rope displacement sensor, and the hanging ring is fixedly connected to the first housing. The installation mechanism is disposed on the first housing and is used to install and fix the first housing to the mounting base.

[0007] Preferably, the mounting mechanism includes a first cavity, a positioning slot, a second housing, a first positioning block, and a positioning mechanism. The first cavity is formed within the mounting base, and an mounting opening is formed between the first cavity and the mounting slot. The positioning slot is formed on two opposite sidewalls of the mounting opening. The second housing is fixedly mounted on the sidewall of the first housing and communicates with the first housing. The second housing extends through the mounting opening into the first cavity. The first positioning block is fixedly mounted on two opposite sidewalls of the second housing. The first positioning block extends into the positioning slot and is slidably connected to the positioning slot. The positioning mechanism is disposed within the second housing and is used to position the second housing relative to the mounting base.

[0008] Furthermore, the positioning mechanism includes a positioning port, a positioning disk, a positioning column, a rotating mechanism, and a moving mechanism. The side wall of the second housing has two positioning ports on the side of the first positioning block away from the first housing. The positioning disk is slidably disposed within the first housing. The positioning column passes through and is rotatably disposed on the positioning disk. Two second positioning blocks are fixedly disposed on the side wall of the positioning column. The second positioning blocks extend into the second housing through adjacent positioning ports. The rotating mechanism is disposed on the positioning column and is used to drive the positioning column to rotate. The moving mechanism is disposed on the positioning disk and is used to drive the positioning disk to move within the first housing.

[0009] Furthermore, the rotating mechanism includes a drive port, a drive prism, and a first handwheel. The drive port is located on the positioning post. The drive prism is rotatably disposed between the bottom side wall of the first housing and the inner top wall of the second housing. The drive prism passes through the drive port and is clearance-fitted with the drive port. This fit allows relative sliding between the drive prism and the drive port along the axial direction, but prohibits relative rotation, thereby ensuring that the rotation of the drive prism can drive the positioning post to rotate. The first handwheel is rotatably disposed on the side wall of the first housing and is fixedly connected to the drive prism.

[0010] Furthermore, a torsion spring is fitted onto the drive prism, and the two ends of the torsion spring are fixedly connected to the inner bottom wall of the first housing and the drive prism, respectively.

[0011] Based on the above scheme, the moving mechanism includes a threaded rod, a second handwheel, and a guide rod. The threaded rod is rotatably disposed inside the first housing and passes through the positioning disk through a threaded engagement. The second handwheel is rotatably disposed on the side wall of the first housing and is fixedly connected to the threaded rod. A plurality of guide rods are fixedly disposed inside the first housing and pass through the positioning disk and are slidably connected to the positioning disk.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, through the setting of the positioning mechanism, the rotation of the first handwheel can drive the drive prism to rotate, and at the same time, through the cooperation of the drive prism and the drive port, the positioning column is driven to rotate, and through the rotation of the positioning column, the second positioning block is aligned with the first positioning block. Then, during the process of extending the first housing into the mounting groove, the first positioning block can be extended into the positioning through groove, and the second positioning block can be extended into the first cavity through the positioning through groove. Then, through the first handwheel, under the elastic force of the torsion spring, the positioning column can be driven to rotate, and the second positioning block and the first positioning block will be misaligned. This facilitates the fixing of the first housing through the cooperation of the second positioning block with the side wall of the first cavity and the cooperation of the first housing with the mounting groove. When it is necessary to adjust the monitoring position, the first housing and the pull rope displacement sensor can be disassembled and their positions changed by rotating the first handwheel and tightening the bolts, thus facilitating the change of the monitoring point.

[0014] 2. In this utility model, by setting up a moving mechanism, after the installation of the first housing is completed, the rotation of the second handwheel can drive the threaded rod to rotate. At the same time, the threaded rod and the positioning plate are engaged by the thread to drive the positioning plate, positioning column and second positioning block to move, thereby facilitating the driving of the second positioning block to press against the side wall of the first cavity, thereby improving the installation stability of the first housing and thus improving the monitoring accuracy.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-6As shown, this embodiment proposes an inflatable membrane building deformation monitoring system for detecting the deformation of an air-supported membrane body 2 fixed to a building retaining wall 1. The system includes a mounting base 3, a first housing 5, a pull-rope displacement sensor 6, and an installation mechanism. Multiple mounting bases 3 are fixed to the inner top wall of the air-supported membrane body 2 with adhesive. The bottom side wall of each mounting base 3 has an installation groove 4. The first housing 5 is slidably disposed within the installation groove 4. The pull-rope displacement sensor 6 is bolted to the building retaining wall 1. A hanging ring is fixedly mounted at the output end of the pull-rope displacement sensor 6, and the hanging ring is fixedly connected to the first housing 5. The installation mechanism is disposed on the first housing 5 and is used to install and fix the first housing 5 to the mounting base 3. Specifically, the installation and disassembly of the first housing 5 and the pull-rope displacement sensor 6 can be achieved by rotating the installation mechanism and the bolts, thereby facilitating adjustment of the deformation monitoring position.

[0025] Reference Figures 1-6The installation mechanism includes a first cavity 7, a positioning groove 9, a second housing 10, a first positioning block 11, and a positioning mechanism. The first cavity 7 is formed within the mounting base 3. An installation opening 8 is provided between the first cavity 7 and the mounting groove 4. Positioning grooves 9 are provided on the two opposite side walls of the installation opening 8. The second housing 10 is fixedly mounted on the side wall of the first housing 5 and communicates with the first housing 5. The second housing 10 extends through the installation opening 8 into the first cavity 7. The first positioning block 11 is fixedly mounted on the two opposite side walls of the second housing 10. The first positioning block 11 extends into the positioning groove 9 and is slidably connected to the positioning groove 9. The positioning mechanism is located within the second housing 10 and is used to position the second housing 10 and the mounting base 3. The positioning mechanism includes... The second housing 10 includes positioning ports 12, positioning discs 13, positioning posts 14, a rotating mechanism, and a moving mechanism. Two positioning ports 12 are provided on the side wall of the second housing 10, on the side of the first positioning block 11 away from the first housing 5. The positioning disc 13 is slidably disposed within the first housing 5. The positioning post 14 passes through and is rotatably disposed on the positioning disc 13. Two second positioning blocks 15 are fixedly disposed on the side wall of the positioning post 14, extending into the second housing 10 through adjacent positioning ports 12. The rotating mechanism is disposed on the positioning post 14 to drive the positioning post 14 to rotate. The moving mechanism is disposed on the positioning disc 13 to drive the positioning disc 13 to move within the first housing 5. The rotating mechanism includes a drive port, a drive prism 16, and a first handwheel 17. The drive port is... On the positioning post 14, a drive prism 16 is rotatably mounted between the bottom side wall of the first housing 5 and the inner top wall of the second housing 10. The drive prism 16 passes through the drive port, and the drive prism 16 and the drive port are in clearance fit. This fit allows relative sliding between the drive prism 16 and the drive port along the axial direction, but prohibits relative rotation, thereby ensuring that the rotation of the drive prism 16 can drive the positioning post 14 to rotate. A first handwheel 17 is rotatably mounted on the side wall of the first housing 5 and is fixedly connected to the drive prism 16. A torsion spring 18 is fitted on the drive prism 16, and both ends of the torsion spring 18 are fixedly connected to the inner bottom wall of the first housing 5 and the drive prism 16, respectively. Specifically, the rotation of the first handwheel 17 can drive the drive prism 16 to rotate. Simultaneously, the driving prism 16, in conjunction with the driving port, drives the positioning pin 14 to rotate. This rotation of the positioning pin 14 aligns the second positioning block 15 with the first positioning block 11. Then, as the first housing 5 is inserted into the mounting groove 4, the first positioning block 11 extends into the positioning through groove 9, and the second positioning block 15 penetrates the positioning through groove 9 and extends into the first cavity 7. Subsequently, the first handwheel 17, under the elastic force of the torsion spring 18, drives the positioning pin 14 to rotate, causing the second positioning block 15 to misalign with the first positioning block 11. This facilitates the fixation of the first housing 5 through the engagement of the second positioning block 15 with the side wall of the first cavity 7 and the engagement of the first housing 5 with the mounting groove 4. When the monitoring position needs adjustment...The first housing 5 and the rope displacement sensor 6 can be disassembled and their positions changed by rotating the first handwheel 17 and tightening the bolts, thus facilitating the modification of the monitoring point.

[0026] Reference Figures 2-6 The moving mechanism includes a threaded rod 19, a second handwheel 20, and guide rods 21. The threaded rod 19 is rotatably disposed within the first housing 5 and passes through the positioning disk 13 via a threaded engagement. The second handwheel 20 is rotatably disposed on the side wall of the first housing 5 and is fixedly connected to the threaded rod 19. Multiple guide rods 21 are fixedly disposed within the first housing 5, passing through the positioning disk 13 and slidably connected to it. Specifically, after the first housing 5 is installed, the threaded rod 19 can be rotated by rotating the second handwheel 20. Simultaneously, the threaded engagement between the threaded rod 19 and the positioning disk 13 drives the positioning disk 13, the positioning post 14, and the second positioning block 15 to move, thereby facilitating the driving of the second positioning block 15 to press against the side wall of the first cavity 7, thus improving the installation stability of the first housing 5 and improving monitoring accuracy.

[0027] It should also be noted that the rope displacement sensor 6 can be connected to a signal transceiver via a signal line, thereby enabling the signal transceiver to remotely transmit the deformation amount to the monitoring personnel.

[0028] In this embodiment, during use, the operator rotates the first handwheel 17. The rotation of the first handwheel 17 drives the drive prism 16 to rotate, and simultaneously, through the cooperation of the drive prism 16 and the drive port, it drives the positioning pin 14 to rotate. The rotation of the positioning pin 14 causes the second positioning block 15 to align with the first positioning block 11. Then, during the process of inserting the first housing 5 into the mounting groove 4, the first positioning block 11 can extend into the positioning through groove 9, and the second positioning block 15 can penetrate the positioning through groove 9 and extend into the first cavity 7. Then, through the first handwheel 17, under the elastic force of the torsion spring 18, the positioning pin 14 can be driven to rotate, causing the second positioning block 15 to be misaligned with the first positioning block 11. This facilitates the fixing of the first housing 5 through the cooperation of the second positioning block 15 with the side wall of the first cavity 7 and the cooperation of the first housing 5 with the mounting groove 4. After that, The installation of the pull rope displacement sensor 6 is achieved by rotating the bolt, which facilitates the monitoring of the deformation of the air film body 2 through the pull rope displacement sensor 6. When it is necessary to adjust the monitoring position, the first housing 5 and the pull rope displacement sensor 6 can be disassembled and their positions changed by rotating the first handwheel 17 and tightening the bolt, which facilitates the change of the monitoring point. After the first housing 5 and the pull rope displacement sensor 6 are reinstalled, the threaded rod 19 can be rotated by rotating the second handwheel 20. At the same time, the threaded rod 19 and the positioning plate 13 are moved by the threaded engagement of the threaded rod 19 and the positioning plate 13, which facilitates the movement of the positioning plate 13, the positioning post 14 and the second positioning block 15. This facilitates the driving of the second positioning block 15 to press against the side wall of the first cavity 7, thereby improving the installation stability of the first housing 5 and thus improving the monitoring accuracy.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
