Description

Technical Field

[0001] The utility model relates to the technical field of tunnel disease data collection, and more specifically to a portable device for collecting tunnel disease distribution spatial characteristic data. Background Art

[0002] Tunnels are man-made structures built underground. During operation, they inevitably develop defects such as structural cracks, water leakage, concrete spalling, and weakening, posing risks to safe tunnel operations. To dynamically understand the technical condition of the structure, it is necessary to promptly record any defects discovered. This allows managers to conduct statistical analysis of tunnel defects and assess their technical condition. This data serves as the basis for maintenance decisions and plans. Portable devices are typically used to collect spatial distribution characteristics of tunnel defects.

[0003] The existing portable device for collecting spatial characteristic data of tunnel disease distribution consists of a laser ranging sensor, an LED high-brightness light sheet, a protective cover and a high-transmittance protective mirror, an inertial attitude sensor, a data wireless transmission device and a power supply battery, as well as a main on / off switch button, an LED high-brightness light on / off switch, a data collection press button, a single-point press button for canceling the operation and an operation instruction circuit, a control output circuit, a control board, a charging port and a one-handed holding shell. The portable device first locates the relative spatial pile number position. Specifically, the cross-sectional pile number of the portable device is input through the supporting app, and the cross-sectional spatial base point is selected; the relative position of the portable device is determined, and the data is synchronously transmitted to the supporting app for storage. In actual use, when the operator carries it, the whole device does not have a structure to protect the high-transmittance protective mirror. If an accident occurs during the carrying process, it is easy to scratch the lens; thereby affecting its accuracy or making it impossible to use normally. For this reason, we propose a portable device for collecting spatial characteristic data of tunnel disease distribution. Utility Model Content

[0038] Method for collecting spatial characteristic data of defect distribution. Before collecting spatial characteristic data of tunnel defect distribution using a portable device, the portable device first locates the relative spatial pile number position. Specifically, the section pile number where the portable device is located is input through the supporting app, the cross-section spatial base point is selected, the relative position of the portable device is determined, and the data is synchronously transmitted to the supporting app for storage.

[0039] The selection of cross-sectional spatial base points generally adopts the method of selecting characteristic points on the tunnel section that are easy to identify, such as the intersection point between the top surface of the tunnel cable trench and the tunnel lining, the intersection point between the outer trench wall of the tunnel and the tunnel pavement, etc.

[0040] The relative position of the portable device is determined by defining the base point illumination, horizontal illumination distance, and inertial attitude sensor acquisition parameters.

[0041] The spatial characteristic data collection method of disease distribution, the spatial characteristic data of tunnel disease distribution, uses the laser emitted by the laser ranging sensor of a portable device to depict the disease, and synchronously collects the distance and posture data and transmits it to the supporting app in real time.

[0042] The method for collecting spatial characteristic data of defect distribution uses a portable device to synchronously collect distance and posture data and transmits them to a supporting app in real time. The supporting app's specific algorithm calculates the spatial characteristic data of tunnel defect distribution based on the collected distance and posture data, saves the data, and outputs and displays it on the supporting app for real-time verification by the operator.

[0043] When the movable guard plate 2641 and the end portion of the fixed mounting ring 26 are overlapped, the connecting spring 2662 can push the connecting mounting plate 2663, drive the connecting positioning rod 2664 to move, so that the end portion of the connecting positioning rod 2664 can be inserted into the inner side of the fixed positioning groove 2643, thereby limiting the movable guard plate 2641, so that the movable guard plate 2641 can stably block the end portion of the fixed mounting ring 26, thereby providing stable protection, simple structure, and convenient and quick operation.
