Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall testing technology, specifically a glass curtain wall breakage detection device. Background Technology

[0002] A glass curtain wall is a building envelope or decorative structure that is supported by a structural system and can move relative to the main structure to a certain extent, without sharing the loads of the main structure. The wall can be single-pane or double-pane glass. Glass curtain walls are an aesthetically pleasing and innovative method of building wall decoration, and a prominent feature of the modernist high-rise building era.

[0003] Currently, a large number of station buildings use glass curtain walls, but the methods for detecting glass breakage are relatively limited. Most rely on the microphone inside the detector to receive sound to determine whether the glass is broken. However, there is a lot of noise in the waiting room, which is affected by electric bells, electric fans, compressors, platform broadcasts, and mechanical equipment, resulting in a noisy sound received by the detector, which can easily affect the accuracy of the detection. Utility Model Content

[0004] The purpose of this invention is to provide a glass curtain wall breakage detection device, which can at least solve some of the defects in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glass curtain wall breakage detection device, comprising a detection component for detecting the glass curtain wall and a driving component for driving the detection component to move within the area of ​​the glass curtain wall, wherein the detection component includes a camera for detecting changes in light and shadow on the glass curtain wall and a spraying mechanism for spraying liquid onto the glass curtain wall.

[0006] Furthermore, it also includes an extension rod for changing the detection position of the detection component to expand the detection range, the detection component being mounted on the extension rod.

[0007] Furthermore, the spraying mechanism includes a liquid storage pipe and an electric spray head for spraying liquid from the liquid storage pipe.

[0008] Furthermore, it also includes a guide rail parallel to the glass curtain wall, and the driving component drives the detection component to move along the extension direction of the guide rail.

[0009] Furthermore, the driving component includes a guide slider that can move the detection component and a driving member for driving the guide slider to slide on the guide rail.

[0010] Furthermore, a drive rack is provided at the position where the guide rail contacts the guide slider. The direction in which the drive rack extends is the same as the direction in which the guide rail extends. The drive component includes a drive gear disposed on the guide slider and a servo motor for driving the drive gear to rotate. The drive gear meshes with the drive rack.

[0011] Furthermore, the guide slider is provided with a gear groove for mounting the drive gear.

[0012] Furthermore, each end of the guide rail is provided with a plug rod and a receiving hole, and the plug rod of the adjacent guide rail is inserted into the receiving hole of the corresponding guide rail.

[0013] Furthermore, it also includes a light-shielding component for shielding the camera from light.

[0014] Furthermore, the light-shielding component includes a sliding baffle that can be moved from the side of the camera's line of sight to in front of the camera's line of sight, and the sliding baffle is provided with a light-shielding lens.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A glass curtain wall breakage detection device, through a drive component, moves the detection component within the area of ​​the glass curtain wall. Anomalies can be observed through a camera. If an anomaly is confirmed, liquid can be sprayed onto the glass surface above the anomaly through a spraying mechanism. The water flows downward under the action of gravity and passes over the anomaly. If the anomaly is a crack, the water droplets will seep into the interior of the crack, causing a significant change in the light and shadow of the crack. Thus, by changing the camera's shooting angle, the changes in the light and shadow of the crack, combined with the effect of the water droplets on the refraction of light on the crack, can determine whether there is a crack in the glass.

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a glass curtain wall breakage detection device, including a detection component for detecting the glass curtain wall and a drive component 5 for moving the detection component within the area of ​​the glass curtain wall. The detection component includes a camera for detecting changes in light and shadow on the glass curtain wall and a spraying mechanism 7 for spraying liquid onto the glass curtain wall. In this embodiment, the drive component 5 moves the detection component within the area of ​​the glass curtain wall. Anomalies can be observed through the camera. If an anomaly is identified, liquid can be sprayed onto the glass surface above the anomaly using the spraying mechanism 7. The water flows downward under gravity and passes over the anomaly. If the anomaly is a crack, the water droplets will seep into the crack, causing a significant change in light and shadow. Thus, by changing the camera's shooting angle, the changes in light and shadow on the crack, combined with the effect of the water droplets refracting light through the crack, are used to determine whether a crack exists in the glass. Specifically, since the glass curtain wall has a large area, the drive component 5 is needed to move the detection component to detect every location, ensuring comprehensive and thorough detection. The detection method can employ a combination of a camera and a spraying mechanism 7. First, the camera (preferably a panoramic camera 9) observes any anomalies on the glass curtain wall. After detecting an anomaly, the spraying mechanism 7 sprays some liquid onto the affected area. For example, a small amount of water with a distinct color (a colored liquid is best, but colorless liquids are also acceptable) is sprayed onto the glass curtain wall. The water will naturally flow downwards under gravity. If the anomaly is a crack, the water droplets will seep into the crack, causing a noticeable change in the light and shadow of the crack due to light refraction. The camera can more easily observe this change to determine if a crack will occur at that location. Preferably, the water storage pipe 71 is fixedly connected to the extension rod 6.

[0023] Please see Figures 1 to 4 The device also includes an extension rod 6 for changing the detection position of the detection component to expand the detection range, with the detection component mounted on the extension rod 6. In this embodiment, the glass curtain wall is typically large, and using the extension rod 6 to send the detection component further away allows for more comprehensive detection. Preferably, the extension rod 6 can also be used in conjunction with the aforementioned drive component 5, where the drive component 5 drives the extension rod 6 to move, and the extension rod 6 then moves the detection component. In another embodiment, the extension direction of the extension rod 6 is not limited to the vertical direction shown in this embodiment; it can also be inclined, and the length is not limited, as long as it can cover the currently detected glass curtain wall area. Multiple detection components can be used to achieve coverage, such as the two sets of detection components shown in this embodiment, arranged in an overlapping manner, which allows the camera's field of view to overlap, ensuring that no area to be detected is missed, thereby improving detection accuracy. Preferably, a mounting groove 8 can be provided at the bottom of the extension rod 6 for mounting the camera.

[0024] Please see Figures 1 to 4 The spraying mechanism 7 includes a liquid storage pipe and an electric spray head 72 for spraying liquid from the liquid storage pipe. In this embodiment, liquid is stored in the liquid storage pipe and then sprayed onto the glass curtain wall by the electric spray head 72. The electric spray head 72 is existing technology, and its spraying mechanism can be remotely controlled, for example, by using Bluetooth, WIFI, etc., thus controlling the timing and amount of spraying.

[0025] Please see Figures 1 to 4 The device also includes a guide rail 3 parallel to the glass curtain wall, and the driving component 5 drives the detection component to move along the extension direction of the guide rail 3. In this embodiment,

[0026] Please see Figures 1 to 4 The device also includes a connecting plate 1 that can be fixedly installed on a glass curtain wall and is parallel to the glass curtain wall. In this embodiment, the connecting plate 1 serves to house various components, such as guide rails 3, which can be mounted on the connecting plate 1. The connecting plate 1 can be connected to the glass curtain wall via connecting screws 2. The connecting plate 1 has guide rails 3 parallel to the glass curtain wall. A tracked cable is provided at the top of the connecting plate 1 to provide power to the device. In use, the connecting plate 1 is installed on the support rod inside the glass curtain wall via the connecting screws 2. However, it is not impossible to directly attach the guide rails 3 to the glass curtain wall; their position is not limited only by the connecting plate 1. The connecting plate 1 provides a more convenient way to install the guide rails 3. Multiple connecting screws 2 can be provided, located at the four corners of the square connecting plate 1.

[0027] Please see Figures 1 to 4The driving component 5 includes a guide slider 4 that can move the detection component and a driving member for driving the guide slider 4 to slide on the guide rail 3. In this embodiment, the driving method is to move in conjunction with the guide rail 3. First, the driving member drives the guide slider 4 to move on the guide rail 3, and then the guide slider 4 drives the detection component.

[0028] For further optimization of the above solution, please refer to [link / reference]. Figures 1 to 4 To further refine the aforementioned driving method, a driving rack 51 is provided at the contact position between the guide rail 3 and the guide slider 4. The driving rack 51 extends in the same direction as the guide rail 3. The driving component includes a driving gear 53 mounted on the guide slider 4 and a servo motor 52 for driving the driving gear 53 to rotate. The driving gear 53 meshes with the driving rack 51. In this embodiment, linear drive is achieved using a gear and rack combination, with the gear rotation achieved by the servo motor 52. Of course, the driving component is not limited to the linear drive form of gear and rack; a linear driving component can also be used directly to push the guide slider 4, such as using an electric push rod, or other driving structures, such as lead screw transmission, to output linear driving force. Preferably, the guide slider 4 is provided with a gear groove 54 for mounting the driving gear 53, which facilitates the mounting of the driving gear 53.

[0029] Please see Figures 1 to 4 Each guide rail 3 has a connecting rod 31 and a receiving hole 32 at both ends. The connecting rod 31 of an adjacent guide rail 3 is inserted into the receiving hole 32 of the corresponding guide rail 3. In this embodiment, the connecting rod 31 and receiving hole 32 facilitate the splicing of two adjacent guide rails 3. Generally, glass curtain walls are very large, and a single guide rail 3 may not be able to cover the entire glass curtain wall for inspection. Therefore, multiple guide rails 3 can be used in combination to expand the inspection range of the equipment for glass curtain walls. Each guide rail 3 has a connecting rod 31 and a receiving hole 32 at both ends. During splicing, they are spliced ​​left and right, with the connecting rod 31 of one guide rail 3 inserted into the receiving hole 32 of the adjacent guide rail 3, and then fixed by some fixing method, such as screws.

[0030] Please see Figures 1 to 4 The device also includes a light-shielding component for shielding the camera from light. In this embodiment, when strong sunlight interferes with the camera's detection, the light-shielding component can be used to block the strong light, thereby reducing the intensity of the sunlight and preventing it from affecting the detection.

[0031] Please see Figures 1 to 4The light-blocking component described above is further refined. It includes a sliding baffle 10 that can move from the side of the camera's line of sight to in front of the camera's line of sight. The sliding baffle 10 is equipped with a light-blocking lens 11. In this embodiment, the light-blocking method utilizes the light-blocking lens 11 on the sliding baffle 10. The light-blocking lens 11 is an existing lens, and the degree of light blocking can be selected as needed. The sliding baffle 10 can move from the side of the camera to in front of it. The position of the light-blocking can be selected as needed. For example, if it provides good light blocking when directly in front of the camera, it is moved to the direct front; if it provides good light blocking when slightly in front of the camera, it is moved to the slightly in front of the camera. Preferably, the movement of the sliding baffle 10 can be achieved using a linear drive mechanism such as an electric telescopic rod 12. The electric telescopic rod 12 is positioned corresponding to the guide slider 4 and the sliding baffle 10. The telescopic end of the electric telescopic rod 12 is fixedly connected to the sliding baffle 10. Of course, other existing linear driving methods are also possible, such as the examples given in the above embodiments. This embodiment does not limit these methods.
