Description

Technical Field

[0001] The present invention belongs to the field of safety control of construction site openings, and particularly relates to a modular construction opening protection system with a protection status monitoring function. Background Art

[0002] There are a large number of openings reserved for construction needs and installation of equipment pipelines at the construction site. These holes often become the main factors for high - altitude falling casualties. To ensure safety during the construction process, these openings often need to be temporarily closed, and the closing methods vary according to the size of the openings:

[0003] Large openings are often closed with steel pipes, wooden squares and wooden boards, and then protective railings are installed around them. The safety of this type of opening protection is relatively high.

[0004] Medium - sized and small - sized openings are often covered with steel plates or wooden boards. Due to the insecure covering, the cover plates often shift. When construction workers pass by, it will cause harm to people. Minor injuries are bumps, and serious injuries can cause falls and fractures or even more serious consequences. In addition, the patent (ZL202020040783.7) invented a cover plate that can adapt to different opening sizes. The cover plate includes a cover plate body and a positioning component. The cover plate body is used to block the opening, and the positioning component is arranged on one side of the cover plate body. Among them, the positioning component includes a moving part and an elastic part. The moving part is arranged on the cover plate body and can slide relative to the cover plate body; one end of the moving part is fixed relative to the cover plate body, and the other end abuts against one end of the moving part. By compressing the elastic part, the other end of the moving part abuts against the inner wall of the opening. When the opening size is different, the compression degree of the elastic part is different. Due to the compression of the elastic part, the moving part abuts against the inner wall of the opening, so that it can be applicable to openings of different sizes.

[0005] The patent (202020914892.7) invented a pre - clampable opening protection device, including an opening cover plate. An adjustment groove is provided on the opening cover plate, and two threaded rods are inserted through the adjustment groove. Nuts are arranged at the upper ends of the two threaded rods, and hanging plates parallel to the opening cover plate are arranged at the lower ends of the threaded rods. By moving the threaded rods in the adjustment groove, the hanging plates contact the lower surface of the opening while the threaded rods contact the side wall of the hole, so as to realize the covering of the opening by the opening cover plate.

[0006] The above - mentioned cover plates have the following problems. First, the cover plates are integrally designed, with large volume and heavy weight, making it difficult to carry and move. Second, the information about the movement of the cover plates cannot be obtained in real time, and the potential safety hazards cannot be eliminated immediately. Third, the cover plate structure is single and cannot well adapt to the changes in opening size and load. Summary of the Invention

[0007] The present invention aims to invent a modular construction opening protection system with a protection status monitoring function, which has a self-sensing function of displacement and can identify whether the opening protection device has been displaced. In addition, it forms an opening protection device adapted to different opening sizes and loads through component combination.

[0008] To solve the above technical problems, the present invention provides the following technical solutions:

[0009] A modular construction opening protection system with a protection status monitoring function, comprising: an opening protection device, a plurality of sensors, a data acquisition and transmission device, and a control system. The opening protection device includes a plurality of load-bearing combined rods and a plurality of panels. The plurality of load-bearing combined rods are arranged at intervals at the opening, and the panels are laid on the plurality of load-bearing combined rods. Each load-bearing combined rod includes a horizontally arranged connector and two load-bearing components. The two load-bearing components are movably connected to both ends of the connector. Each load-bearing component includes a load-bearing rod, an L-shaped upper opening limiting member for clamping the upper edge of the opening, and an L-shaped lower opening limiting member for clamping the lower edge of the opening. Opposite-direction internal threads are respectively provided at both ends of the connector. One ends of the load-bearing rods of the two load-bearing components are respectively threadedly connected to both ends of the connector. By rotating the connector, the length of the corresponding load-bearing combined rod can be adjusted. The other ends of the load-bearing rods of the two load-bearing components are respectively fixedly connected to the corresponding L-shaped upper opening limiting members. The L-shaped lower opening limiting member is connected to the L-shaped upper opening limiting member through a rotating shaft, and the L-shaped lower opening limiting member can rotate around the axis of the rotating shaft. A sensor is respectively arranged between the upper opening limiting horizontal rod of the load-bearing combined rods at the four corner positions of the opening and the floor. The sensors are respectively connected to the data acquisition and transmission device, and the data acquisition and transmission device can send the information collected by the sensors to the control system for displacement monitoring of the opening protection device.

[0010] Preferably, in the above modular construction opening protection system with protection status monitoring function, the L-shaped upper opening limiting member is an L-shaped structure formed by vertically connecting an upper opening limiting horizontal rod and an upper opening limiting vertical rod. The upper end of the upper opening limiting vertical rod is vertically connected to one end of the upper opening limiting horizontal rod. The other ends of the two load-bearing rods are respectively vertically connected to the corresponding upper opening limiting vertical rods. The upper opening limiting horizontal rod is placed on the floor slab of the opening. The L-shaped lower opening limiting member includes a lower opening limiting screw rod, a lower opening limiting smooth rod, and a lower opening limiting nut. One end of the lower opening limiting screw rod is vertically connected to one end of the lower opening limiting smooth rod to form an L-shaped structure. The lower opening limiting screw rod is threadedly connected to the lower opening limiting nut. The lower opening limiting nut is connected to the lower end of the corresponding upper opening limiting vertical rod through a rotating shaft. When the lower opening limiting smooth rod rotates around the axis of the rotating shaft to the horizontal state, it abuts against the lower surface of the floor slab. By adjusting the position of the lower opening limiting nut on the lower opening limiting screw rod, the distance between the upper opening limiting horizontal rod and the lower opening limiting smooth rod can be adjusted, so that the distance between the upper opening limiting horizontal rod and the lower opening limiting smooth rod can adapt to floor slabs of different thicknesses.

[0011] Preferably, in the above modular construction opening protection system with protection status monitoring function, a load-bearing member anti-loosening structure is provided on each load-bearing member. The load-bearing member anti-loosening structure includes an adjusting nut, a limiting block, a threaded connecting rod, a clamping member, a connecting rod, a stop block, a baffle plate, and an anti-loosening spring. The load-bearing rod is provided with a cavity. The threaded connecting rod, the clamping member, the connecting rod, the baffle plate, and the anti-loosening spring are arranged in the cavity of the load-bearing rod. One end of the threaded connecting rod is provided with an external thread and is threadedly connected to the adjusting nut. The other end of the threaded connecting rod is coaxially and fixedly connected to the clamping member and the connecting rod respectively. The clamping member is located outside the connecting rod. A vertical baffle plate is provided at the end of the connecting rod far from the clamping member. One end plate is provided at the end of the load-bearing rod connected to the connector. One end of the anti-loosening spring is connected to the baffle plate, and the other end is connected to the end plate. One end of the adjusting nut is exposed outside. The limiting block is fixedly arranged inside the load-bearing rod, and a through hole for the adjusting nut to pass through is provided on the limiting block. The stop block is fixedly arranged inside the load-bearing rod, and a through hole for the connecting rod to pass through is provided on the stop block. The clamping member includes a pair of outwardly curved claws and a mounting disk. The pair of outwardly curved claws are symmetrically arranged on the mounting disk. The mounting disk is fixedly sleeved on the threaded connecting rod. A slope matching the claws is provided on the side of the stop block opposite to the clamping member. An opening groove for the claws to pass through is provided on the rod wall of the load-bearing rod. A groove for the claws to extend into is provided at the end of the connector.

[0012] Preferably, in the above modular construction opening protection system with protection status monitoring function, when the L-shaped lower opening limit member is fastened to the floor slab, the L-shaped lower opening limit member touches the adjusting nut. The adjusting nut drives the clamping member to move backward through the threaded connecting rod and compresses the anti-loosening spring. When the clamping claw moves backward, it is blocked by the stop block and is squeezed upward along the slope of the stop block. When the groove of the connector rotates to the position of the clamping claw, the clamping claw enters the groove, making the connector locked and unable to rotate. When it is necessary to release the locking of the connector, rotate the adjusting nut so that the adjusting nut moves axially along the threaded connecting rod away from the L-shaped lower opening limit member, creating a gap between the lower opening limit screw rod and the adjusting nut. The baffle moves forward under the action of the anti-loosening spring, and the baffle drives the clamping member to withdraw from the groove of the connector through the connecting rod and the threaded connecting rod, and the connector resumes its rotation function.

[0013] Preferably, in the above modular construction opening protection system with protection status monitoring function, the L-shaped lower opening limit member is designed by weight ratio and always remains open in the natural state. When the lower opening limit screw rod touches the opening wall, it starts to rotate until the lower opening limit screw rod is in a vertical state and the lower opening limit smooth rod is in a horizontal state, so that the lower opening limit screw rod and the lower opening limit smooth rod are in contact with the opening edge.

[0014] Preferably, in the above modular construction opening protection system with protection status monitoring function, the load-bearing rods and the panels have different size specifications for selection. During use, they are assembled according to the size of the opening and the upper load conditions to form an assembled opening protection device suitable for different opening sizes and upper loads. The load-bearing rods are designed with different lengths. The shortest load-bearing rod is defined as level 1, the slightly longer one is positioned as level 2, and the longer one is positioned as level 3, and so on. The length of the level 1 load-bearing rod is L1, the adjustable length of the connector is L0, and the lengths of the first 4 levels of load-bearing rods are L1, L1 + L0, L1 + 3L0, and L1 + 7L0 respectively.

[0015] Preferably, in the above modular construction opening protection system with protection status monitoring function, based on the medium-width opening, the cross-sectional dimensions of the load-bearing rods and the lateral spacing of adjacent load-bearing combined members are designed. When the opening width decreases, the lateral spacing of the load-bearing combined members is increased according to the calculation results; when the opening width increases, the lateral spacing of the load-bearing combined members is decreased according to the calculation results, so as to adapt to different opening widths and upper loads by adjusting the lateral spacing of the load-bearing combined members.

[0016] Preferably, in the above modular construction opening protection system with protection status monitoring function, to adapt to different lateral spacings of the load-bearing combined members, two waist-shaped holes are respectively arranged at both ends of the panel, and the panel is connected to the load-bearing component as a whole through panel fastening bolts, and the waist-shaped holes are perpendicular to the axial direction of the load-bearing combined members.

[0017] Preferably, in the above modular construction opening protection system with protection status monitoring function, the sensor includes a support block, two cushion blocks, a sensing spring, an inverted U-shaped cover, contact point A, contact point B, contact point C, and an electronic tag. The support block is arranged on the floor slab. The inverted U-shaped cover includes a top plate and side walls. The top of the side walls is arranged around the top plate. The two cushion blocks are arranged on the support block at intervals. The inverted U-shaped cover is arranged outside the two cushion blocks and the support block. The top plate is located above the cushion blocks, and the side walls are located outside the support block. The sensing spring is arranged between the top plate and the support block. The contact point B is arranged on the side surface of the support block. The contact point A and the contact point C are arranged on the inner surface of the side wall of the inverted U-shaped cover at intervals. The contact point A is located above the contact point C. The four sensors, the data acquisition and transmission device, and the power supply are connected in series to form a circuit. When an L-shaped upper opening limit piece is arranged on the inverted U-shaped cover of the sensor, the contact point A and the contact point B are in contact, and the corresponding electronic tag is not connected to the circuit, and there is no current passing through the corresponding electronic tag. When the L-shaped upper opening limit piece arranged on the inverted U-shaped cover of the sensor is removed, the contact point C and the contact point B are in contact, and the corresponding electronic tag is connected to the circuit, and there is current passing through the corresponding electronic tag. The data acquisition and transmission device can send the information of whether the current of the electronic tag passes through to the control system to monitor the displacement of the opening protection device.

[0018] Preferably, in the above modular construction opening protection system with protection status monitoring function, when each sensor is pressed, there is no current passing through the corresponding electronic tag, and the data acquisition and transmission device sends data at a certain time interval to report that the opening protection device is in a safe state; when a sensor is not pressed, there is current passing through the corresponding electronic tag, and the data acquisition and transmission device immediately pushes the abnormal information of the opening protection device.

[0019] As can be seen from the above disclosed technical solutions, compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This embodiment discloses a modular construction opening protection system with a protection status monitoring function, which adopts an opening protection device, a number of sensors, a data acquisition and transmission device, and a control system. The opening protection device includes a number of load-bearing combined rods and a number of panels. The number of load-bearing combined rods are arranged at intervals at the opening, and the panels are laid on the number of load-bearing combined rods. Each load-bearing combined rod includes a horizontally arranged connector and two load-bearing components. The two load-bearing components are movably connected to both ends of the connector. Each load-bearing component includes a load-bearing rod, an L-shaped upper opening limiting member, and an L-shaped lower opening limiting member. Opposite internal threads are provided at both ends of the connector. One ends of the load-bearing rods of the two load-bearing components are respectively threadedly connected to both ends of the connector. By rotating the connector, the length of the corresponding load-bearing combined rod can be adjusted. The other ends of the load-bearing rods of the two load-bearing components are respectively fixedly connected to the corresponding L-shaped upper opening limiting members. The L-shaped upper opening limiting member is an L-shaped structure formed by vertically connecting an upper opening limiting horizontal rod and an upper opening limiting vertical rod. The upper end of the upper opening limiting vertical rod is vertically connected to one end of the upper opening limiting horizontal rod. The other ends of the two load-bearing rods are respectively vertically connected to the corresponding upper opening limiting vertical rods. The upper opening limiting horizontal rod is placed on the floor slab of the opening. The L-shaped lower opening limiting member includes a lower opening limiting screw rod, a lower opening limiting smooth rod, and a lower opening limiting nut. One end of the lower opening limiting screw rod is vertically connected to one end of the lower opening limiting smooth rod to form an L-shaped structure. The lower opening limiting screw rod is threadedly connected to the lower opening limiting nut. The lower opening limiting nut is connected to the lower end of the corresponding upper opening limiting vertical rod through a rotating shaft. When the lower opening limiting smooth rod rotates around the axis of the rotating shaft to a horizontal state, it abuts against the lower surface of the floor slab. By adjusting the position of the lower opening limiting nut on the lower opening limiting screw rod, the distance between the upper opening limiting horizontal rod and the lower opening limiting smooth rod can be adjusted, so that the distance between the upper opening limiting horizontal rod and the lower opening limiting smooth rod can adapt to floor slabs of different thicknesses. Sensors are respectively arranged between the upper opening limiting horizontal rods of the load-bearing combined rods at the four corner positions of the opening and the floor slab. The sensors are respectively connected to the data acquisition and transmission device. The data acquisition and transmission device can send the information collected by the sensors to the control system for displacement monitoring of the opening protection device, so that the modular construction opening protection system has the function of self-sensing the displacement of the opening protection device, can identify whether the position of the opening protection device has been moved, and can give an alarm in time after the opening protection device is displaced, reminding the management personnel to maintain as soon as possible, thereby effectively avoiding the risk of falling and injury to construction workers caused by the displacement of the opening protection device.

Detailed implementation manners

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The technical content and features of the present invention will be described in detail below with the listed embodiments in conjunction with the accompanying drawings. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention. For the convenience of description, the "upper" and "lower" described below are in the same direction as the upper and lower of the accompanying drawings, but this cannot be a limitation to the technical solution of the present invention.

[0044] Please refer to Figures 1 to 21, this embodiment discloses a modular construction opening protection system with a protection status monitoring function, including: an opening protection device, several sensors 5, a data acquisition and transmission device 6, and a control system. The opening protection device includes several load-bearing combined members and several panels 3. The several load-bearing combined members are arranged at intervals at the opening, and the panel 3 is laid on the several load-bearing combined members. Each load-bearing combined member includes a horizontally arranged connector 1 and two load-bearing components 2. The two load-bearing components 2 are movably connected to both ends of the connector 1. Each load-bearing component 2 includes a load-bearing rod 21, an L-shaped upper opening limiting member 22 for clamping the upper edge of the opening, and an L-shaped lower opening limiting member 23 for clamping the lower edge of the opening. Opposite-direction internal threads are respectively provided at both ends of the connector 1. One ends of the load-bearing rods 21 of the two load-bearing components 2 are respectively threadedly connected to both ends of the connector 1. By rotating the connector 1, the length of the corresponding load-bearing combined member can be adjusted. The other ends of the load-bearing rods 21 of the two load-bearing components 2 are respectively fixedly connected to the corresponding L-shaped upper opening limiting members 22. The L-shaped lower opening limiting member 23 is connected to the L-shaped upper opening limiting member 22 through a rotating shaft, and the L-shaped lower opening limiting member can rotate around the axis of the rotating shaft. A sensor 5 is respectively arranged between the upper opening limiting horizontal rods 221 of the load-bearing combined members located at the four corner positions of the opening and the floor 8. The sensors 5 are respectively connected to the data acquisition and transmission device 6. The data acquisition and transmission device 6 can send the information collected by the sensors 5 to the control system for displacement monitoring of the opening protection device, so that the modular construction opening protection system has the function of self-sensing the displacement of the opening protection device, can identify whether the position of the opening protection device has been moved, and can give an alarm in time after the opening protection device is displaced to remind the management personnel to maintain it as soon as possible, thus effectively avoiding the risk of falling and injury of construction workers caused by the displacement of the opening protection device.

[0045] Preferably, in the above modular construction opening protection system with protection status monitoring function, the L-shaped upper opening limiting member 22 is an L-shaped structure formed by vertically connecting an upper opening limiting horizontal rod 221 and an upper opening limiting vertical rod 222. The upper end of the upper opening limiting vertical rod 222 is vertically connected to one end of the upper opening limiting horizontal rod 221. The other ends of the two load-bearing rods 21 are respectively vertically connected to the corresponding upper opening limiting vertical rods 222. The upper opening limiting horizontal rod 221 is placed on the floor slab 8 of the opening. The L-shaped lower opening limiting member 23 includes a lower opening limiting screw rod 231, a lower opening limiting smooth rod 232 and a lower opening limiting nut 233. One end of the lower opening limiting screw rod 231 is vertically connected to one end of the lower opening limiting smooth rod 232 to form an L-shaped structure. The lower opening limiting screw rod 231 is threadedly connected to the lower opening limiting nut 233. The lower opening limiting nut 233 is connected to the lower end of the corresponding upper opening limiting vertical rod 222 through a rotating shaft 234. When the lower opening limiting smooth rod 232 rotates around the rotating shaft 234 to the horizontal state, it abuts against the lower surface of the floor slab 8. By adjusting the position of the lower opening limiting nut 233 on the lower opening limiting screw rod 231, the distance between the upper opening limiting horizontal rod 221 and the lower opening limiting smooth rod 232 can be adjusted, so that the distance between the upper opening limiting horizontal rod 221 and the lower opening limiting smooth rod 232 can adapt to floor slabs 8 of different thicknesses.

[0046] Preferably, in the above modular construction opening protection system with protection status monitoring function, there are two rotating shafts 234, which are symmetrically arranged on the outer surface of the lower opening limiting nut 233. The rotating shafts 234 are respectively perpendicular to the lower opening limiting screw rod 231. Two upper opening limiting vertical rods 222 are used. The lower ends of the two upper opening limiting vertical rods 222 are respectively sleeved on the corresponding rotating shafts 234, so that the lower opening limiting nut 233 can rotate relative to the corresponding upper opening limiting vertical rod 222 on the premise of not affecting the relative movement between the lower opening limiting nut 233 and the lower opening limiting screw rod 231.

[0047] Preferably, in the modular construction opening protection system with a protection status monitoring function described above, a load-bearing member anti-loosening structure 4 is provided on each load-bearing member 2. The load-bearing member anti-loosening structure 4 includes an adjusting nut 41, a limiting block 42, a threaded connecting rod 43, a clamping member 44, a connecting rod 45, a stop block 46, a baffle 47, and an anti-loosening spring 48. The load-bearing rod 21 is provided with a cavity. The threaded connecting rod 43, the clamping member 44, the connecting rod 45, the baffle 47, and the anti-loosening spring 48 are arranged in the cavity of the load-bearing rod 21. One end of the threaded connecting rod 43 is provided with an external thread and is threadedly connected to the adjusting nut 41. The other end of the threaded connecting rod 43 is coaxially and fixedly connected to both the clamping member 44 and the connecting rod 45. The clamping member 44 is located outside the connecting rod 45. A vertical baffle 47 is provided at the end of the connecting rod 45 away from the clamping member 44. One end plate is provided at the end of the load-bearing rod 21 connected to the connector 1. One end of the anti-loosening spring 48 is connected to the baffle 47, and the other end is connected to the end plate. One end of the adjusting nut 41 is exposed to the outside. The limiting block 42 is fixedly arranged inside the load-bearing rod 21, and a through hole for the adjusting nut 41 to pass through is provided on the limiting block 42. The stop block 46 is fixedly arranged inside the load-bearing rod 21, and a through hole for the connecting rod 45 to pass through is provided on the stop block 46. The clamping member 44 includes a pair of outwardly curved claws 441 and a mounting disc 442. The pair of outwardly curved claws 441 are symmetrically arranged on the mounting disc 442. The mounting disc 442 is fixedly sleeved on the threaded connecting rod 43. A slope matching the claws 441 is provided on one side of the stop block 46 opposite to the clamping member 44. An opening groove 211 for the claws 441 to pass through is provided on the rod wall of the load-bearing rod 21. A groove 11 for the claws 441 to extend into is provided at the end of the connector 1.

[0048] Preferably, in the above modular construction opening protection system with protection status monitoring function, when the L-shaped lower opening limiter 23 is fastened to the floor slab 8, i.e., the L-shaped lower opening limiter 23 is stuck at the lower edge of the opening, the L-shaped lower opening limiter 23 (specifically, the lower opening limit screw 231) touches the adjusting nut 41. The adjusting nut 41 drives the clamping member 44 to move backward through the threaded connecting rod 43 and compresses the anti-loosening spring 48. When the claw 441 moves backward, it is blocked by the stop block 46 and is squeezed upward along the slope of the stop block 46. When the groove 11 of the connector 1 rotates to the position of the claw 441, the claw 441 enters the groove 11, so that the connector 1 is locked and cannot rotate. When it is necessary to release the lock of the connector 1, rotate the adjusting nut 41 so that the adjusting nut 41 moves axially along the threaded connecting rod 43 in a direction away from the L-shaped lower opening limiter 23, creating a gap between the lower opening limit screw 231 and the adjusting nut 41. The baffle 47 moves forward under the action of the anti-loosening spring 48. The baffle 47 drives the clamping member 44 to withdraw from the groove 11 of the connector 1 through the connecting rod 45 and the threaded connecting rod 43, and the connector 1 resumes its rotation function.

[0049] Preferably, in the above modular construction opening protection system with protection status monitoring function, the L-shaped lower opening limiter is designed by weight ratio and always remains open in the natural state. When the lower opening limit screw touches the opening wall, it starts to rotate until the lower opening limit screw is in a vertical state and the lower opening limit smooth rod is in a horizontal state, so that the lower opening limit screw and the lower opening limit smooth rod contact the opening edge.

[0050] Preferably, in the above modular construction opening protection system with protection status monitoring function, the L-shaped lower opening limiter 23 is designed by weight ratio and always remains open in the natural state. When the lower opening limit screw 231 touches the opening wall, it starts to rotate until the lower opening limit screw 231 is in a vertical state and the lower opening limit smooth rod 232 is in a horizontal state, so that the lower opening limit screw 231 and the lower opening limit smooth rod 232 contact the opening edge, that is, the L-shaped lower opening limiter 23 is locked with the opening.

[0051] Preferably, in the above modular construction opening protection system with protection status monitoring function, according to the concept of standardization and modularization, the opening protection device is disassembled into different components. The load-bearing rod 21 and the panel have different size specifications for selection. The load-bearing rod 21 is designed with different lengths, and the panel is designed with different sizes. During use, according to the size of the opening and the upper load conditions, the components are selected for assembly to form an assembled opening protection device with displacement monitoring function suitable for different opening sizes and upper loads.

[0052] Preferably, in the above modular construction opening protection system with a protection status monitoring function, in order to adapt to different opening widths and upper loads, the load-bearing rods 21 are designed with different lengths. After the load-bearing rods 21 of different lengths are connected by the connector 1, they can be applied to openings of different widths. The shortest load-bearing rod 21 is defined as level 1, the slightly longer one is positioned as level 2, and the longer one is positioned as level 3, and so on. The principle for determining the rod length is as follows:

[0053] To ensure that the load-bearing rods 21 can cover the entire opening range after connection, the length of the level 1 load-bearing rod 21 is L1, and the adjustable length of the connector 1 is L0. As can be seen from the following Figure 1 After combining 2 level 1 load-bearing rods 21 with the connector 1 (after the load-bearing rods 21 are anchored into the connector 1 with a safe length), the length is 2L1 + L0. As the connector 1 rotates, the load-bearing rod 21 continuously penetrates into the connector 1. When the ends of the two connectors 1 come into contact, the connector 1 cannot rotate. At this time, the combined structure length of the load-bearing rod 21 is the shortest, which is 2L1

[0054] Therefore, the covered opening width range is: 2L1 - 2L1 + L0

[0055] Let the length of the level 2 load-bearing rod 21 be L2 = L1 + L0

[0056] Through the combination of L1 and L2, the covered opening width range at this time is: 2L1 ~ 2L2 + L0 = 2L1 + 3L0

[0057] When designing the length of L3, considering that the combination of L3 and the shortest section L1 can meet the docking coverage with the longest 2L2 + L0 of the previous level combination, the optimal combination of rod lengths can be achieved.

[0058] 2L2 + L0 = L3 + L1

[0059] Then L3 = 2L2 + L0 - L1. Substitute L2 = L1 + L0 into it

[0060] L3 = L2 + 2L0

[0061] The covered opening width range of the three length combinations of L1, L2, and L3 is: 2L1 ~ 2L3 + L0

[0062] The calculation method of the length of L4 is similar to that of L3. After the combination of L4 and L1, it is connected to the widest of the previous level, and the maximum utilization of all rod lengths can be achieved:

[0063] L4 + L1 = 2L3 + L0

[0064] L4 = 2L3 + L0 - L1

[0065] L4 = 2L3 + L0 - L1

[0066] L4 = L3 + 4L0

[0067] Therefore, it can be determined that the lengths of the first four levels of load-bearing rods 21 are L1, L1 + L0, L1 + 3L0, L1 + 7L0 respectively. By analogy, the lengths of other load-bearing rods 21 can be calculated.

[0068] In this embodiment, the load-bearing rods 21 are designed with different lengths. After the load-bearing rods 21 with different lengths are connected and combined through the connector 1, they can be applied to openings with different widths. The shortest load-bearing rod 21 is defined as the first level, the slightly longer one is positioned as the second level, and the longer one is positioned as the third level, and so on. The length of the first-level load-bearing rod 21 is L1, the length that the connector 1 can adjust is L0, and the lengths of the first four levels of load-bearing rods 21 are L1, L1 + L0, L1 + 3L0, L1 + 7L0 respectively.

[0069] Preferably, since the load borne by the opening protection device changes correspondingly with the change of the opening width, in order to ensure the bearing safety and consider the economy of the opening protection device, taking the medium-width opening as the reference, the cross-sectional dimensions of the load-bearing rods 21 and the lateral spacing of adjacent load-bearing combined members are designed. When the opening width decreases, the lateral spacing of the load-bearing combined members is increased according to the calculation results; when the opening width increases, the lateral spacing of the load-bearing combined members is decreased according to the calculation results, so as to adapt to different opening widths and upper loads by adjusting the lateral spacing of the load-bearing combined members.

[0070] Preferably, in the above modular construction opening protection system with a protection state monitoring function, in order to adapt to different lateral spacings of the load-bearing combined members, two waist-shaped holes 31 are respectively arranged at both ends of the panel. The panel 3 and the load-bearing member 2 are connected into an integral body through the panel fastening bolts 7. The waist-shaped holes 31 are perpendicular to the axial direction of the load-bearing combined members, and panel fixing limit holes 212 for installing the panel fastening bolts 7 are provided on the load-bearing rods 21.

[0071] Preferably, in the above modular construction opening protection system with protection status monitoring function, the sensor 5 includes a support block 51, two cushion blocks 52, a sensing spring 53, an inverted U-shaped cover 54, a contact point A 55, a contact point B 56, a contact point C 57, and an electronic tag 58. The support block 51 is arranged on the floor slab 8. The inverted U-shaped cover 54 includes a top plate 541 and side walls 542. The tops of the side walls 542 are arranged around the top plate 541. The two cushion blocks 52 are arranged on the support block 51 at intervals. The inverted U-shaped cover 54 is arranged outside the two cushion blocks 52 and the support block 51. The top plate 541 is located above the cushion blocks 52. The side walls 542 are located outside the support block 51. The sensing spring 53 is arranged between the top plate 541 and the support block 51. The contact point B 56 is arranged on the side surface of the support block 51. The contact point A 55 and the contact point C 57 are arranged on the inner surface of the side wall 542 of the inverted U-shaped cover 54 at intervals. The contact point A 55 is located above the contact point C 57. The four sensors 5, the data acquisition and transmission device 6, and the power supply 9 are connected in series to form a loop. When the L-shaped upper opening limit piece 22 is arranged on the inverted U-shaped cover 54 of the sensor 5, the contact point A 55 and the contact point B 56 are in contact, and the corresponding electronic tag 58 is not connected to this loop, and there is no current passing through the corresponding electronic tag 58. When the L-shaped upper opening limit piece 22 arranged on the inverted U-shaped cover 54 of the sensor 5 is removed, the contact point C 57 and the contact point B 56 are in contact, and the corresponding electronic tag 58 is connected to this loop, and there is current passing through the corresponding electronic tag 58. The data acquisition and transmission device 6 can send the information of whether the current of the electronic tag 58 passes through to the control system to monitor the displacement of the opening protection device.

[0072] Preferably, in the above modular construction opening protection system with protection status monitoring function, when each sensor 5 is pressed, there is no current passing through the corresponding electronic tag 58, and the data acquisition and transmission device 6 sends data at a certain time interval to report that the opening protection device is in a safe state. When a sensor 5 is not pressed, there is current passing through the corresponding electronic tag 58, and the data acquisition and transmission device 6 immediately pushes the abnormal information of the opening protection device. Thus, by changing the sending frequency of the data acquisition and transmission device 6, the power consumption of the system can be reduced, so that long-term reliable monitoring can be realized by using ordinary batteries.

Any changes and modifications made by those of ordinary skill in the art of the present invention according to the above disclosure shall fall within the protection scope of the claims.
