Description

Technical Field

[0001] This utility model relates to the field of sensing device technology, specifically to a glass curtain wall panel self-explosion early warning sensing device. Background Technology

[0002] Glass curtain wall panels are a widely used exterior wall cladding structure in modern buildings. They are typically non-load-bearing exterior wall systems composed of glass panels and supporting structures (such as aluminum alloy frames, stainless steel structures, or point-connected components). They not only provide an aesthetically pleasing visual effect but also possess certain functional properties.

[0003] After prolonged use, some glass curtain wall panels may crack. When existing tempered glass curtain wall panels spontaneously explode, the entire panel tilts outward, creating a falling object. Current methods to prevent this include manual inspection, which is incomplete and prone to delays in detection, and the use of external protective nets to passively catch the fragments. However, this method affects aesthetics and may also pose a risk of glass fragments falling. Therefore, we propose a glass curtain wall panel spontaneous explosion early warning sensing device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass curtain wall panel self-explosion early warning sensing device, comprising a glass panel and sensing chips, wherein sensing chips are provided at the four corners of the glass panel, and two sets of connecting wires are electrically connected to the sensing chips. An "L"-shaped hidden groove is provided on the glass panel to connect the surface of the glass panel with the side wall, and the connecting wires are inserted into the hidden groove; it also includes an environmental modification module for alarm and changing indoor negative pressure.

[0006] Furthermore, the glass panel is made of double-layered glass, and the sensing chip is disposed in the interlayer of the glass panel.

[0007] Furthermore, the sensing chip is disposed at one of the four corners of the glass panel, and a support mechanism for attaching the sensing chip to the glass panel is bonded at each of the four corners of the glass panel.

[0008] Furthermore, the environment change module includes a data acquisition unit, an alarm module, a relay, and an air conditioner fan AC contactor coil. The output terminal of the sensing chip is electrically connected to the input terminal of the data acquisition unit. The output terminal of the data acquisition unit is electrically connected to an alarm module for alarm processing. The air conditioner fan AC contactor coil is mounted on the external air conditioner fan. The output terminal of the alarm module is electrically connected to the air conditioner fan AC contactor coil via a relay.

[0009] Furthermore, the alarm module includes a buzzer alarm and a sensor light strip installed in the central control room.

[0010] Furthermore, the sensing chip is configured as a passive resistance strain gauge chip.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1:

[0017] Please see Figures 1-3 This utility model provides a technical solution: a glass curtain wall panel self-explosion early warning sensing device, including a glass panel 1 and a sensing chip 2. The sensing chip 2 is provided at each of the four corners of the glass panel 1. Two sets of connecting wires 5 are electrically connected to the sensing chip 2. An "L"-shaped hidden groove 4 is opened on the glass panel 1 to connect the surface of the glass panel 1 with the side wall. The connecting wires 5 are inserted into the hidden groove 4. It also includes an environmental change module 3 for alarm and changing indoor negative pressure.

[0018] The sensor chip 2 is located at the four corners of the glass panel 1, which can detect changes in the glass panel 1 in a timely manner. The hidden groove 4 can hide the connecting wire harness 5 connected to the sensor chip 2, ensuring the aesthetics of the glass panel 1. The environmental change module can issue an alarm in a timely manner when it detects changes in the data of the sensor chip 2, and can also reduce the negative pressure in the indoor environment, which can change the direction of the glass panel 1 falling off after it breaks to a certain extent.

[0019] Please see Figures 1-3 The glass panel 1 is made of double-layer glass, and the sensing chip 2 is disposed in the interlayer of the glass panel 1. The placement of the sensing chip 2 in the interlayer of the glass panel 1 will not affect the aesthetics of the glass panel 1, and it is convenient to place the sensing chip 2 in the interlayer during the production of the glass panel 1.

[0020] Please see Figures 1-3The environmental change module includes a data acquisition unit 6, an alarm module 7, a relay 8, and an air conditioner fan AC contactor coil 9. The output terminal of the sensing chip 2 is electrically connected to the input terminal of the data acquisition unit 6. The data acquisition unit 6 has a metal casing and contains multiple Wheatstone bridge interfaces, an amplifier circuit, and switch output terminals. The data acquisition unit 6 is installed in the ceiling of the building. The output terminal of the data acquisition unit 6 is electrically connected to the alarm module 7 for alarm processing. The air conditioner fan AC contactor coil 9 is installed on the external air conditioner fan. The output terminal of the alarm module 7 is electrically connected to the air conditioner fan AC contactor coil 9 through the relay 8.

[0021] When the sensing chip 2 detects a change in the glass panel 1, it directly transmits the data to the data acquisition unit 6 and triggers an alarm through the alarm module 7, reminding staff to perform timely maintenance. Subsequently, the relay 8 activates the AC contactor coil 9 of the air conditioning fan, cutting off the operation of the indoor air conditioning fan and reducing the indoor negative pressure. In low-altitude curtain walls, the pressure difference between the inside and outside is basically equal, and the pressure reduction inside makes the internal pressure less than the external pressure. This can increase the probability that the glass panel 1 will fall inward after breaking, rather than falling outward and injuring people. In high-altitude curtain walls, the internal pressure is greater than the external pressure. Continuous pressure reduction may balance the inside and outside or make the internal negative pressure less than the external negative pressure, causing the broken glass panel 1 to fall inward.

[0022] Please see Figures 1-3 The alarm module 7 includes a buzzer alarm 10 and a sensor light strip 11 installed in the central control room. The alarm module 7 includes a buzzer alarm 15 and a sensor light strip 16, which can achieve two alarm modes: sound and light alarm. The two alarm modes can remind the staff in the central control room to observe the changes of the glass panel 1 in time.

[0023] Please see Figures 1-3 The sensing chip 2 is configured as a passive resistance strain gauge chip. Since the sensing chip 2 is a passive resistance strain gauge chip, it can detect the data changes of the glass panel 1 by simply using two sets of connecting wires 5 without the need for software calculation units.

[0024] In use, the sensor chip 2 is first positioned at the four corners of the glass panel 1, allowing for timely observation of changes in the glass panel 1. The concealed slot 4 hides the connecting wire harness 5 connected to the sensor chip 2, ensuring the aesthetics of the glass panel 1. The environmental change module then issues an alarm promptly upon detecting changes in the data collected by the sensor chip 2, and can also reduce indoor negative pressure, thus altering the direction of the glass panel 1's fall should it break. Once the sensor chip 2 detects a change in the glass panel 1, it directly transmits the data to the data acquisition unit 6, and triggers an alarm via the alarm module 7. The system prompts staff to perform timely maintenance. Subsequently, relay 8 activates the AC contactor coil 9 of the air conditioner fan, which cuts off the operation of the indoor air conditioner fan, thereby reducing the indoor negative pressure. The alarm module 7 includes a buzzer alarm 15 and a sensor light strip 16, which can achieve both audible and visual alarms. These two alarm methods can remind the staff in the central control room to observe changes in the glass panel 1 in a timely manner. Moreover, the sensing chip 2 adopts a passive resistance strain gauge chip, which can detect changes in the data of the glass panel 1 using only two sets of connecting wires 5 without the need for software calculation units.

[0025] Example 2:

[0026] Please see Figures 4-5 The sensing chip 2 is disposed at the four corners of the outer side of the glass panel 1, and a support mechanism 12 for attaching the sensing chip 2 to the glass panel 1 is bonded at each of the four corners of the glass panel 1.

[0027] The sensing chip 2 is mounted on the glass panel 1 via the support mechanism 12, which allows the sensing chip 2 to always be in contact with the glass panel 1 for detection and facilitates the disassembly and maintenance of the sensing chip 2.

[0028] Please see Figures 4-5 The supporting mechanism 12 includes a mounting shell 13, positioning posts 14, telescopic sleeves 15, mounting plates 16, and springs 17. The mounting shell 13 is made of stainless steel and is bonded to the glass panel 1. Multiple sets of positioning posts 14 are fixedly installed inside the mounting shell 13. Telescopic sleeves 15 are sleeved on the outside of the positioning posts 14. The mounting plate 16 is fixedly connected to one side of the telescopic sleeve 15. A spring 17 is fixedly connected between the inner wall of the mounting shell 13 and the mounting plate 16, and outside the telescopic sleeve 15.

[0029] The sensor chip 2 is installed on the mounting plate 16, and then the mounting shell 13 made of stainless steel is glued to the glass panel 1. The spring 17 can push the telescopic sleeve 15 and the positioning post 14 to extend, so that the sensor chip 2 can always be in contact with the surface of the glass panel 1, and the data of the surface of the glass panel 1 can be monitored in real time.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
