[0002] Water conservancy projects refer to various engineering measures that use engineering technology to develop, utilize, control and protect water resources. These projects are aimed at meeting human society’s demand for water, such as water supply, irrigation, flood control, power generation, etc., and ensuring the health and stability of the ecosystem.

[0003] The purpose of surveying and mapping water conservancy projects before construction is to obtain accurate basic data, optimize planning and design, ensure construction safety, guide the construction process, and support final acceptance. These preliminary preparations not only help ensure the quality and safety of the project, but also effectively reduce construction costs and improve the economic and social benefits of the project.

[0004] However, the existing remote mapping equipment has the following shortcomings:

[0005] Water conservancy projects must be based on natural water sources, and the selected objects are mostly rivers, lakes, and other places. Due to the complex terrain environment, it is not conducive to manual surveying and mapping. With the development of technology, existing surveying and mapping equipment is often used in conjunction with drones to solve the limitations brought by the terrain. However, the biggest disadvantage of overhead surveying is that part of the position of the measured object will be blocked by objects, such as trees or man-made buildings, resulting in insufficient data obtained in the later stage, which affects the formulation of subsequent plans.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The effect achieved by the entire embodiment 1 is as follows: since the device is equipped with a central gyroscope 25, it can further accurately detect whether there is an angular deviation of the body, ensuring that the connected upper support plate 4 can be in a horizontal state. By utilizing the collaboration of relevant components, the shooting component 14 can be guided by gravity to face the ground, and the image within the field of view can be captured in real time. With the high-speed descent and the assistance of relevant system modules, the position of each docking component can be quickly captured, and the splicing process can be completed autonomously. The power component and the mapping component are fixed by the principle of electromagnetic adsorption. This method can not only ensure that the mapping component can collect data from above, but also land in complex areas with the cooperation of the drone body 1 to collect detailed data.

[0033] Embodiment 2, according to Figure 4 , Figure 6 and Figure 7As shown, the discharge end of the battery pack 21 is fixedly connected to a group of second transmission wires 24, and the output ends of the group of second transmission wires 24 are all connected to the input end of the lower wire collection square plate 23. The bottom of the lower wire collection square plate 23 is fixedly connected to an electrical control box 32, and an extended side cover 27 is fixedly installed with an organic variable component 35 on the outer wall, and the output end of the organic variable component 35 is connected to one end of the outer wall of the first cross bar 28.

The battery pack 21 is fixedly installed inside the rectangular shell 20, and a group of independent brackets 22 are fixedly installed at the bottom of the lower support plate 19. A lower wire collection square plate 23 is fixedly installed between the inner surface walls of a group of independent brackets 22, and the bottom of the lower wire collection square plate 23 An inner slot 26 is provided on the part, two extended side covers 27 are fixedly installed on the bottom of the lower wire collection square plate 23, a first cross bar 28 is movably inserted between the opposite sides of the two extended side covers 27, the outer wall of the first cross bar 28 is fixedly sleeved with a first linkage seat 29, a first external frame 30 is fixedly installed on the bottom of the first linkage seat 29, a surveying instrument body 31 is fixedly installed on the front surface of the first external frame 30, an external guide head 33 is fixedly connected to one side of the outer wall of the electrical control box 32, an enhanced antenna 34 is fixedly connected to the inside of the external guide head 33, a third wiring seat 36 is fixedly connected to the rear surface of the first external frame 30, a group of second information lines 37 are fixedly connected to the inside of the third wiring seat 36, and the output ends of the group of second information lines 37 are all connected to the wiring terminals of the electrical control box 32.

[0034] The effect achieved by the entire embodiment 2 is as follows: through the cooperation of the above-mentioned mechanical components, the surveying and mapping instrument body 31 can be rotated 180°, and the scanning target can be flexibly changed in the overhead state. When the surveying and mapping component lands in a complex area, the supporting component is horizontally flattened, and the viewing angle is also quickly aligned with the predicted mapping target. The surveying and mapping data are temporarily stored in the relevant modules in the electrical control box 32, and are quickly imported back to the terminal system by remote data transmission, or the screen contained in the electrical control box 32 is manually operated to retrieve the temporarily stored data from the module for viewing. This layout method can ensure that both surveying and mapping methods are not restricted by external conditions, and can flexibly change the surveying and mapping methods according to reasonable terrain changes, thereby increasing the adequacy of subsequent data.

[0035] Embodiment 3, according to Figure 2 , Figure 7 and Figure 8As shown, the outer wall of each independent bracket 22 is fixedly installed with a second external bracket 38, and a second cross bar 39 is movably inserted between the opposite sides of each two second external brackets 38. The outer wall of each second cross bar 39 is fixedly sleeved with a second linkage seat 40, and the outer wall of each second linkage seat 40 is fixedly installed with two load-bearing brackets 41, and the end of each load-bearing bracket 41 is fixedly installed with an extension bracket 42, and the interior of each extension bracket 42 is fixedly inserted with a first expansion plate 43, and the outer wall of each first expansion plate 43 is fixedly installed with a first electric push rod 44, and the axial end of each first electric push rod 44 is fixedly sleeved with a square seat 45, and the interior of each square seat 45 is provided with a second rolling sleeve 46, and the interior of each second rolling sleeve 46 is movably provided with a second roller 47, and the interior of each second roller 47 is fixedly inserted with a support foot 48, A non-slip pad 49 is provided at the bottom of each support foot 48, and a flange 50 is fixedly installed on the outer wall of the two second external frames 38, and an electric motor 51 is fixedly installed inside each flange 50, and the output end of each electric motor 51 is respectively connected to one end of the outer wall of a corresponding second cross bar 39, and a solid ring 52 is fixedly sleeved on the outer wall of each second linkage seat 40, and a group of positioning grooves 53 are opened inside each solid ring 52, and a second expansion plate 54 is fixedly installed on the outer wall of the two second external frames 38, and a docking block 57 is fixedly installed on the top of each second expansion plate 54, and a second electric push rod 55 is opened inside the two second external frames 38, and a limiting groove 56 is movably inserted inside each second electric push rod 55, and each limiting groove 56 is respectively connected to the shaft end of a corresponding docking block 57.

[0036] The effect achieved by the entire embodiment 3 is: the complex terrain that has not been artificially repaired will have uneven contact surfaces with the equipment. The above-mentioned components can control the operation of the mechanical components in turn according to the offset data detected by the central gyroscope 25, and the system-related modules can correct each corner one by one, accurately adjust the height of the equipment, ensure that the equipment is in a flat state as a whole, and then complete the evacuation of the drone body 1, so that the surveying and mapping components can more accurately collect the undulating changes in the terrain of this part of the area, reduce the errors in the subsequent data, avoid the need for repeated calibration of the data, and shorten the data collection stage.

[0037] The working principle of the equipment is as follows: in the first surveying and mapping stage, the area to be surveyed is selected, and the flight path of the drone body 1 is set by the control unit according to the distribution of water areas in the terrain. During the execution process, the cross-linked frame 2 and its connected components can be carried by the drone body 1, starting from the beginning of the path, reasonably controlling the flight altitude and speed, turning on the machine variable component 35, and using the movable connection of the extended side cover 27 and the first cross bar 28 to slowly drive the surveying instrument body 31 on the first linkage seat 29 to adjust the angle. Under normal conditions, the viewing angle of the surveying instrument body 31 is in a vertical state, facing the water terrain below, fully All areas included in the path are fully scanned and a complete graph is drawn in real time. If the measured area is small, fixed-point drawing can also be performed. This method is mainly characterized in that the machine-changing component 35 slowly drives the surveying instrument body 31 to continuously change its position, and the turning speed is synchronously controlled according to the scanning rate of the surveying instrument body 31, rotating 180° from left to right or from right to left, and quickly completing the terrain scanning of the measured area. The drawn terrain data can be temporarily stored in the relevant module of the electrical control box 32 through the second information line 37. After the data is completely imported, it can be sent back to the system receiving terminal by wireless transmission through the enhanced antenna 34.

[0038] In the second surveying and mapping stage, the relevant personnel can obtain the partial positions blocked by the external environment based on the complete terrain data, and reset the flight path and landing command of the UAV body 1. When the equipment reaches the position as a whole, it quickly adjusts to the balance of the body and slowly descends the altitude. The camera element conventionally provided on the UAV body 1 is used to shoot the target ground image. The information presented on the picture can be used as a basis for judgment by the relevant technical personnel to reasonably find the best landing point, and then hang above the point, and start the two electric motors 51 simultaneously. The movable connection between the second external frame 38 and the second cross bar 39 is used to slowly drive the two groups of load-bearing brackets 41 to move relative to each other, and continuously reduce the angle between the load-bearing brackets 41 and the lower wire collection square plate 23, and finally make the two groups of load-bearing brackets 41 fall in an eight-shaped shape. At this time, one of the positioning grooves 53 can be directly opposite to one end of the limiting groove 56, and the extended side cover 27 is started to extend its inner axis outward, pushing the limiting groove 56 until it is deeply inserted into the corresponding positioning groove 53, and the landing is completed. The structure of this part is fixed. When each anti-skid pad 49 contacts the ground, the power output of the drone body 1 is stopped in time. Since the ground has not been repaired, there will be unevenness. However, the movable connectivity of the second roller sleeve 46 and the second roller 47 can ensure that the steering of the support leg 48 is not restricted, so that the anti-skid pad 49 can be fully attached to the uneven surface. The offset difference detected by the central gyroscope 25 is shared with the relevant modules in the electrical control box 32 to control each first electric push rod 44, and the height of each corner of the equipment is corrected in turn to ensure that the equipment body is in a parallel state. Then, the energy supply of each electromagnetic sleeve 6 is disconnected, and the drone body 1 can be quickly separated from the mapping component. The machine variable component 35 adjusts the viewing angle range of the mapping instrument body 31, and the target area is scanned horizontally. The drawn terrain data can be quickly transmitted back to the system terminal, and the relevant personnel can integrate the terrain data of the blocked area into the large terrain data to supplement it, and gradually improve the integrity of the terrain data.

[0039] During the retraction stage, the drone body 1 quickly reaches the position above the retention position of the surveying and mapping component. When the body is leveled, it slowly descends in height. By utilizing the movable connectivity of the first roller sleeve 10 and the first roller 11, the viewing direction of the shooting component 14 can be made vertically downward under the gravity applied by the connected components. The wide-angle lens 15 can be used to increase the image capture range. With the cooperation of relevant system modules, the position of each metal plug plate 18 can be quickly found, and the drone body 1 continuously corrects the docking position of each electromagnetic sleeve 6 and the metal plug plate 18 to ensure that each metal plug plate 18 can be inserted into the corresponding electromagnetic sleeve 6 without damage. When each electromagnetic sleeve 6 and the metal plug plate 18 are fully docked, each electromagnetic sleeve 6 is quickly energized to complete the fixation of the drone body 1 and the surveying and mapping component, and then the drone body 1 carries the surveying and mapping component back.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
