Description

Technical Field

[0001] The utility model relates to the field of insulating glass sealing performance detection, in particular to an insulating glass air leakage detection device. Background Art

[0002] Insulating glass is widely used in buildings and is favored for its good heat insulation and sound insulation effects. However, as the use time increases, the sealing performance of insulating glass may gradually decline, and even gas leakage may occur, causing it to lose its original energy-saving and heat-insulating functions. Once the sealing layer fails, the insulating glass will no longer be able to play its due role, which will not only affect the energy-saving effect of the building, but also may pose a safety hazard.

[0003] Because the bearing deformation performance of the hollow layer of insulating glass will change before and after the sealing performance changes, the sealing performance of the hollow layer can be judged by applying concentrated force and to the insulating glass, and measuring the deformation of the inner and outer sheets of the insulating glass and comparing it with the standard value; specifically, when the hollow layer of the insulating glass is in a sealed state, when the outer glass is deformed under force, the volume of the hollow air layer will be compressed, resulting in increased pressure, which affects the difference in deformation of the inner and outer sheets of the glass when the insulating glass is subjected to load in the sealed and leaking states; therefore, it is a common detection method to judge the sealing state of the insulating glass by measuring the deformation of the inner and outer sheets of the glass under the condition of applying load;

[0004] However, the force-applying devices used for detection in the prior art are relatively simple and have great limitations for the detection of curtain wall glass. For example, the lever-weight loading device provided in GB / T37784-2019 (On-site detection method for safety hazards of hollow glass structures) is difficult to detect curtain wall glass at a higher position and has poor scene applicability.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] A hollow glass leakage detection device comprises a spiral forcer 100; a screw rod 110 is threadedly connected to the middle part of the spiral forcer 100; a sensor 130 is connected to one end of the screw rod 110, and a force application rod 111 is provided at the other end; the sensor 130 is connected to a sensor instrument 133 through a data line 132; the sensor instrument 133 can read the pressure data of a pressure head 131; the pressure head 131 of the sensor 130 abuts against the curtain wall glass; a reaction rod 120 perpendicular to the screw rod 110 is connected to the spiral forcer 100; a suction cup 140 is connected to the reaction rod 120; the suction cup 140 is used to be adsorbed on the curtain wall glass;

[0032] In one embodiment, the screw 110 is rotatably connected to the sensor 130, so that when the screw 110 is rotated to apply force, the sensor 130 can remain stationary, thereby preventing the data line 132 of the sensor meter 133 from being entangled;

[0033] In one embodiment, the screw 110 can be fixedly connected to the sensor 130 by a fixing nut 112. When the screw 110 is rotated forward to apply force, the sensor 130 will rotate along with the screw 110, which may cause the data cable 132 to be entangled. Preferably, the sensor instrument 133 is fixedly set on the sensor 130, and the data cable 132 is close to the sensor 130 and can rotate along with the sensor 130 to avoid entanglement of the wire harness. More preferably, the data cable 132 is changed to a connecting plug to reduce the exposure of the wire harness and increase safety.

[0034] In one embodiment, the reaction rod 120 is a long rod that passes through the spiral force multiplier 100 and then extends from both ends; a suction cup 140 is connected to each end of the reaction rod 120; the force rod 111 is rotated to push the screw rod 110 forward so as to apply a load to the curtain wall glass through the pressure head 131, and the suction cup 140 is used to provide a pulling force to ensure that the screw rod 110 can smoothly apply pressure to the pressure head 131; in order to avoid interference between the reaction rod 120 and the screw rod 110, the horizontal through hole accommodating the reaction rod 120 and the vertical threaded hole matching the screw rod 110 need to be set in different planes, which will cause the rotary force multiplier to bear a certain torque during operation, and the reaction rod 120 is relatively long, which is not conducive to storage;

[0035] In one embodiment, in order to facilitate storage of the device, two reaction rods 120 are provided, one end of the reaction rod 120 is provided with a thread, and is threadedly connected to the screw booster 100; the other end of the reaction rod 120 is connected to the suction cup 140; at the same time, this structure can ensure that the reaction rod 120 and the screw rod 110 are located in the same plane, and the force is more evenly applied;

[0036] In one embodiment, the reaction rod 120 is connected to the suction cup 140 through a ring fastener 150; one end of the ring fastener 150 is rotatably connected to the suction cup 140, and the end away from the suction cup 140 is provided with a connecting hole 151; the reaction rod 120 is inserted into the connecting hole 151, and the size of the connecting hole 151 is slightly larger than the diameter of the reaction rod 120. When a load is applied, the reaction rod 120 will deform. Due to the existence of the connecting hole 151 of the ring fastener 150, the reaction rod 120 can rotate freely around the fulcrum 152 of the connecting hole 151. Since the size of the connecting hole 151 is slightly larger than the diameter of the reaction rod 120, the deformation of the reaction rod 120 can connect the two ring fasteners 150 Pulled inwards, and limited by the connecting hole 151, the annular fastener 150 is rotatably connected to the suction cup 140 and can rotate freely, so that during the load application process, the device can adapt to the corresponding deformation and smoothly apply the load; it also makes the suction cup 140 evenly stressed, avoiding falling due to uneven stress during the loading process; further, the reaction rod 120 is inserted into the connecting hole 151 and can be locked by itself after being stressed, which is convenient for installation; preferably, one end of the reaction rod 120 extends out of the connecting hole 151 for a distance, so as to ensure that the reaction rod 120 will not fall off from the connecting hole 151 when it is deformed by force, thereby ensuring the stability of the connection; the reaction rod 120 is usually made of a material with a certain rigidity to reduce deformation when force is applied;

[0037] When the utility model is used, it is preferred to adsorb the suction cup 140 on the adjacent glass of the curtain wall glass 200 to be inspected, so as to reduce the interference of the suction cup 140 on the curtain wall glass 200 to be inspected during adsorption. The connection of the curtain wall glass is connected to the curtain wall keel 220 through the structural adhesive 210. The principle of hollow glass leakage detection is to apply a certain load to the center of the curtain wall glass 200 to be inspected, and measure the deformation amount of the center of the curtain wall glass to compare with the reference value, so as to judge the state of the hollow glass. Therefore, if the suction cup 140 is adsorbed on the hollow glass to be inspected, it will affect the measurement structure, and connecting it to the adjacent curtain wall glass can avoid this influence, ensure that the curtain wall glass 200 to be inspected is only subjected to the pressure of the pressure head 131, and improve the accuracy of detection.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
