DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] The portable dam surface inspection device for an unstable plane according to an embodiment of the present invention comprises a self-balancing component 3, a connecting plate 4, a distance measuring component 5, an image acquisition component 6, a posture meter 8, a moving component 1 and a connecting component 2, wherein the connecting component 2 is detachably connected to the moving component 1, and the connecting component 2 is extended or contracted in the up and down directions.

[0031] One end of the self-balancing component 3 is connected to the telescopic end of the connecting component 2, and a connecting plate 4 is provided at the bottom of the self-balancing component 3.

[0032] The distance measuring component 5 is arranged on the top of the connecting plate 4, and the image collecting component 6 is arranged on the bottom of the connecting plate 4, and the distance measuring component 5 and the image collecting component 6 are arranged in parallel.

[0033] The attitude meter 8 is arranged on the connecting component 2 , and the attitude meter 8 is suitable for monitoring the pitch angles of the distance measuring component 5 and the image acquisition component 6 .

[0034] Specifically, Figures 1 to 3 As shown, the moving component 1 is arranged at the bottom of the device, and the moving component 1 is suitable for moving in a preset inspection path. The connecting component 2 moves in the up and down directions. The self-balancing component 3 is installed at the upper end of the connecting component 2, and the moving component 1 is installed at the lower end of the connecting component 2.

[0035] The connecting plate 4 is connected to the self-balancing component 3. During the movement of the mobile component 1, under special working conditions such as large water level fluctuations and earthquakes and floods, the mobile component 1 may undergo unpredictable movement or vibration in the up and down directions, front and back directions, or left and right directions. The self-balancing component 3 may be an existing stabilizer, for example, a three-axis stabilizer is used to maintain the stability of the distance measuring component 5 and the image acquisition component 6 during the operation of the mobile component 1, to avoid image jitter and inaccurate distance measurement, etc.

[0036] The attitude meter 8 is suitable for monitoring the operating status of the mobile component 1, for example, the inclination angle of the whole device in the up-down direction, or the left-right direction, and the front-back direction, as well as the acceleration or the moving speed, and transmits the data to the self-balancing component 3, so that the self-balancing component 3 can keep the distance measuring component 5 and the image acquisition component 6 stable during the inspection process. At the same time, the attitude meter 8 transmits the inclination angle of the whole device in the up-down direction, the front-back direction, or the left-right direction to the background, and combines the monitoring data of the distance measuring component 5 to determine the actual distance between the monitoring location and the device. After the device is started, the mobile component 1 moves according to the preset path, and the connecting component 2 adjusts the height as needed. The self-balancing component 3 keeps the distance measuring component 5 and the image acquisition component 6 stable, and the attitude meter 8 monitors and adjusts the device attitude in real time. The distance measuring component 5 and the image acquisition component 6 synchronously obtain data, and process and analyze them through the background system to obtain the image of the target position and the distance between the device.

[0037] The portable upstream dam surface rapid inspection device of the unstable plane of the embodiment of the present invention performs inspection of the preset line by setting the mobile component 1, and does not need manual inspection, thereby improving the inspection efficiency, reducing the labor intensity and improving the inspection safety. The linear distance of the detection target is monitored by setting the distance measuring component 5, and the image of the detection target is collected by the image acquisition device. At the same time, the self-balancing component 3 is set to make the image acquisition component 6 have an anti-shake function, which can realize the zoom and rotation operation of the motion camera, thereby facilitating the acquisition of the global and local image data of the detection target. At the same time, the target position is calculated through the data transmitted by the attitude meter 8, and the self-balancing component 3 is adjusted to make the image acquisition component 6 and the distance measuring component 5 operate stably.

[0038] Furthermore, the self-balancing component 3 may be an existing camera stabilizer, so as to prevent the image acquisition component 6 and the distance measuring component 5 from shaking during use.

[0039] In some embodiments, the connecting component 2 includes a shell 21, a mounting bracket 22, a buckle 23 and a telescopic member 24. A buckle 23 is provided at the bottom of the mounting bracket 22 to install the mounting bracket 22 on the moving component 1. The other end of the mounting bracket 22 is connected to the shell 21. The shell 21 has an installation cavity for installing the telescopic member 24, and one end of the telescopic member 24 extends out of the installation cavity and is connected to the self-balancing component 3.

[0040] Specifically, Figures 1 to 3 As shown, the housing 21 has an installation cavity for installing the telescopic member 24, the upper end of the telescopic member 24 extends out of the installation cavity and is connected to the self-balancing component 3, one end of the mounting bracket 22 is connected to the outer peripheral surface of the housing 21, and the other end of the mounting bracket 22 is connected to the moving component 1. The upper end of the telescopic member 24 is connected to the self-balancing component 3, and the telescopic member 24 extends or contracts in the up and down direction to retract the self-balancing component 3 and the distance measuring member 5 into the housing 21, so as to avoid damage to the device during transportation.

[0041] Furthermore, a handle is provided on the shell to facilitate moving and installing the shell.

[0042] Furthermore, the number of mounting brackets 22 can be multiple, and the multiple mounting brackets 22 are arranged at intervals in the circumferential direction of the housing 21 to improve the connection stability between the mounting brackets 22 and the mobile component 1. At the same time, by providing the buckle 23, it is convenient to disassemble the telescopic component 24 and the image acquisition component 6 and the distance measuring component 5 of the self-balancing component 3 from the mobile component 1, so as to facilitate transportation separately. Alternatively, the mobile component 1 on site is used, for example, the mobile component 1 can be an unmanned ship.

[0043] In some embodiments, the mobile component 1 is an unmanned ship or a drone.

[0044] Specifically, Figures 1 to 3 As shown, when the mobile component 1 is an unmanned boat, the unmanned boat can flexibly navigate in various water environments, including rivers, lakes, reservoirs, etc., and is particularly suitable for upstream dam surface inspections in wide waters or complex terrains. Using unmanned boats for inspections can free personnel from harsh working environments. For example, in extreme weather conditions such as floods, the use of unmanned boats reduces the risk of personnel being directly exposed to dangerous environments, ensures the safety of inspectors, significantly reduces labor intensity, and improves work efficiency.

[0045] When the mobile component 1 is a drone, the drone has the ability to fly and can quickly cover a large inspection area, including remote or difficult-to-reach places. The drone, in conjunction with the image acquisition component 6 and the distance measuring component 5, can capture all parts of the levee in an all-round and blind-angle manner, and can obtain image data from the top, slope or foot of the levee. The drone is flexible to prevent water flow from interfering with the operation of the drone, and can easily adjust the flight route and mission plan according to different inspection needs. In some dangerous areas, such as steep areas near the dam body or areas near the shore when the water level is abnormal, drones can replace manual inspections, effectively avoiding safety risks for personnel when performing tasks.

[0046] In some embodiments, the unstable-plane portable dam surface inspection device further includes a positioning component 7, which is installed at one end of the telescopic component 24 away from the housing 21. The positioning component 7 can be a GPS or other existing positioning devices, used to position the overall device during the inspection process, and then cooperate with the distance measuring component 5, the attitude instrument 8 and the image acquisition component 6 to facilitate the personnel to locate the position of the detection target. Or the positioning component 7 can be an existing RTK positioning device. RTK, namely Real-Time Kinematic positioning technology based on carrier phase observations, can provide the three-dimensional positioning results of the measuring station in the specified coordinate system in real time and reach centimeter-level accuracy. It is used to measure the horizontal relative displacement between a series of measuring points in the vertical direction. It is used to realize the real-time positioning of the fast inspection equipment, record the inspection trajectory, and facilitate the personnel to view the flight path and the positioning detection location.

[0047] The positioning component 7 records the geodetic coordinates of the image acquisition device in real time, and then combines with the distance measuring component 5 and the built-in attitude instrument 8. Using trigonometric functions, the straight-line distance of the defect points found by the image acquisition device can be calculated, so as to facilitate the determination of the detection target distance and position information.

[0048] Furthermore, when viewing the subsequent data, the position coordinates of the detection target can be determined by calculating the distance at the same time point of unifying the position information, the attitude instrument data, the rangefinder data and the picture information, so as to determine whether the detection targets are the same.

[0049] In some embodiments, the unstable-plane portable dam surface inspection device further includes a controller and a wireless transmission module. The controller is respectively connected to the wireless transmission module, the attitude instrument 8, the moving component 1, the connecting component 2, the positioning component 7, the distance measuring component 5, the image acquisition component 6 and the self-balancing component 3, and the controller receives or transmits data through the wireless transmission module.

[0050] Specifically, as Figures 1 to 3 shown, the controller is connected to the wireless module. For example, the device can further include a control handle, and the control handle exchanges data with the controller through the wireless transmission module. Moreover, the controller also controls the movement of the moving component 1 through the wireless transmission module. The controller receives the data of the attitude instrument 8 through the wireless transmission module to adjust the self-balancing component 3, and controls the telescopic amount of the telescopic component 24 in the connecting component 2 to facilitate measurement and image acquisition. The data of the distance measuring component 5, the image acquisition component 6 and the positioning component 7 are transmitted to the handle or the memory.

[0051] The geodetic coordinates can be used as basic positioning data for locating the detection target. For example, when taking a picture of the detection target, the distance measuring component 5 always measures the distance at the camera focus. When the image acquisition component 6 is aimed at the detection target, the distance measuring component 5 can collect the straight-line distance between the detection target and the image acquisition component 6. By simultaneously reading the inclination angle of the attitude meter 8, the relative distance between the defect point and the X-axis and Y-axis of the image acquisition component 6 can be calculated. Combined with the geodetic coordinates of the positioning component 7, the geodetic coordinates of the detection target can be calculated, which is convenient for determining the distance and position information of the detection target.

[0052] Furthermore, the non-stable plane portable dam surface inspection device also includes a power supply component and a display screen 9. The power supply component is respectively connected to the wireless transmission module, the attitude indicator 8, the moving component 1, the connecting component 2, the positioning component 7, the ranging component 5, the display screen 9, the image acquisition component 6 and the self-balancing component 3 to supply electric energy, and the controller is connected to the display screen 9.

[0053] The power supply component is connected to the mobile component 1 and the wireless transmission module for power supply. The power supply component can also be connected to the connecting component 2, the ranging component 5 display screen 9, the image acquisition component 6 and the self-balancing component 3 respectively for power supply. The display screen 9 can be set on the shell 21. The controller is connected to the display screen 9 to control the display screen 9 to display the data of the attitude meter 8, the mobile component 1, the ranging component 5 and the image acquisition component 6, which is convenient for the operator to view so as to set the preset parameters of each component before inspection. Furthermore, the wireless transmission module may include a SIM card slot to realize wireless control of the device, cloud transmission, storage and download functions of the data of each component.

[0054] In some embodiments, the non-stable plane portable dam surface inspection device also includes an indicator light 10 and a remote control. The remote control is wirelessly connected to the wireless module, and the remote control transmits data with the controller through the wireless module. The indicator light 10 is connected to the controller.

[0055] The indicator light 10 can display different colors to correspond to different states of the device, or the controller is connected to the indicator light 10 to display the amount of power of the power supply component, and different colors are used to display different amounts of power. Or the controller controls the indicator light 10 to display different colors to distinguish different states of the distance measuring component 5 or the image acquisition component 6. For example, when the distance measuring component 5 is operating normally, the indicator light 10 is displayed in green, and when it fails, it is displayed in red.

[0056] The remote controller is wirelessly connected to the wireless transmission module, so as to facilitate the control of the movement of the mobile component 1, the start and operation of the distance measuring component 5 and the image acquisition component 6 through the wireless transmission module, and the amount of expansion and contraction of the telescopic component 24 in the up and down directions, thereby improving the convenience of using the device.

[0057] Further, a control panel is also provided on the housing 21. The indicator light 10 can be arranged on the control panel. A charging port 11 is provided on the control panel to supply power to the power supply component. A video transmission data port 12 is also provided on the control panel to transmit data of the distance measuring component 5, the image acquisition component 6, the positioning component 7, and the attitude meter 8. A spare data port 13 is provided on the control panel to facilitate the use of the spare data port 13 for transmitting data of the distance measuring component 5, the image acquisition component 6, the positioning component 7, and the attitude meter 8 when the video transmission data port 12 fails or malfunctions.

[0058] Further, the charging port, the plug-in card slot, the power button, the power display, and multiple device interfaces on the control panel can be set according to the actual situation, and the embodiments of the present application do not specifically limit them.

[0059] The usage method of the unstable plane portable dam surface inspection device according to the embodiment of the present invention includes installing and debugging the device, setting the inspection route and inspection speed parameters of the device, starting the inspection and recording the inspection information, and after the inspection operation is completed, turning off the device and exporting the inspection data.

[0060] Specifically, as Figures 1 to 3 shown, first install and debug the overall device, install and connect the connection component 2, the moving component 1, the distance measuring component 5, the attitude meter 8, and the image acquisition component 6. For example, the controller is wirelessly connected to the attitude meter 8, the connection component 2, the moving component 1, the distance measuring component 5, the attitude meter 8, and the image acquisition component 6 through a wireless transmission module, and transmits the data to the remote controller. And it is set that the controller can also be connected to the display screen 9 to display the data of the connection component 2, the moving component 1, the distance measuring component 5, the attitude meter 8, and the image acquisition component 6.

[0061] Set the angle of the image acquisition component 6, the parameters of the self-balancing component 3, the inspection route, and the inspection speed parameters, and click the device start button to start the inspection operation. During the inspection process, the video collected by the image acquisition component 6 is locally magnified, the surrounding environment conditions, the straight-line distance between the device and the detection target, and the position movement trajectory data are obtained through the remote controller.

[0062] Further, when installing and debugging the device, balance calibration is performed on the device and the initial image angle is set for image acquisition, so as to avoid that during the inspection process, the monitoring directions of the image acquisition component 6 and the distance measuring component 5 do not face the inspection target, and improve the stability and safety of the inspection.
