Description

Technical Field

[0002] At present, site measurement is an important link in the early stage of power project construction. It involves the precise acquisition of parameters such as terrain height difference and obstacle distribution.

The lower bracket is horizontally fixedly installed with a mounting platform, and the shock-absorbing platform and the mapping gimbal are positioned and installed based on the mounting platform. A shock-absorbing bracket is fixedly installed on the bottom of the lower bracket. A tilted camera topographic surveying and mapping device is designed. This device is suitable for local shock absorption and falling shock absorption design of the shock-absorbing platform. The brake motor installed on the horizontal plate drives the entire mapping gimbal to rotate for tilted camera topographic surveying and mapping operations. The outer diameter of the positioning connecting rod is covered with a rubber shock-absorbing sleeve for structural shock absorption of the shock-absorbing bracket. When the UAV lands, the shock-absorbing bracket rotates by the central swing axis after the upper horizontal plate is subjected to external force. The arc-shaped support feet provide stable support for the ground, and the support springs provide elastic support for the positions on both sides of the upper horizontal plate to ensure stability during the falling process.

[0004] During use, the device uses a drone equipped with a mapping gimbal to map the terrain, and uses a lower bracket and a shock-absorbing bracket to cushion the impact force generated during landing.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The utility model provides Figures 1 to 6 The shown device is a site measurement device for power engineering construction, including a drone body 1. Two groups of buffer mechanisms are installed on the lower side of the drone body 1. The buffer mechanisms include a support rod 2, an electric motor 22, a positioning groove 23, a positioning block 24, a positioning screw 25, a lifting rod 3, a limit groove 32, a buffer rod 34, a buffer gasket 35 and a limit spring 37. The two groups of support rods 2 are respectively installed on the left and right sides of the lower surface of the drone body 1. The left and right sides of the lower surface of the drone body 1 are fixedly connected to a first mounting plate 11. The inner side of the first mounting plate 11 is provided with a mounting groove 12. The side of the support rod 2 is fixedly connected to a second mounting plate 21. The upper end of the second mounting plate 21 is inserted into the interior of the mounting groove 12. The surfaces of the first mounting plate 11 and the second mounting plate 21 are both provided with connecting holes, and the interior of the connecting hole is provided with fixing screws 13. A connecting plate 4 is installed between the two groups of support rods 2. The lower side of the connecting plate 4 is rotatably connected to a mounting bracket 42, and the inner side of the mounting bracket 42 is rotatably connected to a surveying and mapping gimbal 43.

[0037] Among them, the electric motor 22 is a bidirectional motor and is connected to a remote control module, which can use remote sensing to remotely control its rotation direction. At the same time, control motors are installed on the upper side of the connecting plate 4 and the right side of the mounting bracket 42. Both sets of control motors can also be remotely controlled to adjust the left and right direction and up and down angles of the surveying and mapping gimbal 43.

[0038] In addition, during the installation process, the side of the support rod 2 connected to the second mounting plate 21 is directed inward, and the upper end of the second mounting plate 21 is inserted into the inside of the mounting groove 12. Then, the fixing screw 13 is passed through the connecting hole on its surface and cooperates with the nut to lock the first mounting plate 11 and the second mounting plate 21 to fix the buffer mechanism quickly. Then, the surveying and mapping gimbal 43 is installed between the two sets of support rods 2. During use, the electric motor 22 drives the positioning screw 25 to rotate clockwise, and the positioning screw 25 drives the lifting rods 3 on both sides to move downward through the positioning block 24 to support the drone body 1 and the surveying and mapping gimbal 43. At the same time, during transportation, the electric motor 22 drives the positioning screw 25 to rotate counterclockwise, and the positioning screw 25 drives the lifting rods 3 on both sides to move upward through the positioning block 24, thereby retracting the lifting rods 3 to both sides of the support rod 2, and then the two sets of support rods 2 are stacked together, effectively reducing the space occupied by the low buffer mechanism and greatly improving its convenience in transportation and carrying.

[0039] See Figure 2 、 Figure 3 and Figure 7The two groups of support rods 2 are fixedly connected to the middle position of the side surface close to each other with a connecting block 26, and a clamping groove 27 is opened inside the connecting block 26. The upper surface of the connecting block 26 is slidably connected with a plug-in rod 28, and the surface of the plug-in rod 28 is sleeved with a positioning spring 29. The upper and lower ends of the positioning spring 29 are respectively fixedly connected to the upper surface of the connecting block 26 and the upper end of the plug-in rod 28. The left and right ends of the connecting plate 4 are fixedly connected with a clamping plate 41, and the clamping plate 41 is clamped in the inside of the clamping groove 27. Vertical lock holes are opened on the surface of the connecting plate 4 near the left and right ends, and the lower end of the plug-in rod 28 is inserted into the inside of the lock hole.

[0040] Specifically, during the installation of the surveying and mapping pan-tilt platform 43, one staff member lifts up the two sets of plug-in rods 28, and then another staff member holds the connecting plate 4 and respectively clips the two ends of the connecting plate 4 into the clipping grooves 27 on the left and right sides. Then the staff member loosens the plug-in rod 28. At this time, the plug-in rod 28 is automatically moved downward under the action of the positioning spring 29, and the lower end of the plug-in rod 28 is inserted into the inside of the lock hole to lock and fix the connecting plate 4, thereby installing the surveying and mapping pan-tilt platform 43. In addition, when one person is installing, first insert the clamping plate 41 into the clamping grooves 27 on the left and right sides, and push it inward until the side walls of the connecting plate 4 abut against the plug rods 28, then loosen the connecting plate 4 and lift the two sets of plug rods 28 upward. At this time, use other parts of the body to assist in pushing the connecting plate 4 inward until the clamping plate 41 is completely inserted into the inside of the clamping groove 27, then loosen the plug rod 28, and the lower end of the plug rod 28 is inserted into the inside of the lock hole to lock and fix the connecting plate 4.

[0041] See Figures 3 to 6 The front and rear surfaces of the support rod 2 are provided with positioning grooves 23, and the front and rear ends of the positioning block 24 are respectively slidably connected with the front and rear two sets of positioning grooves 23. The front and rear ends of the positioning block 24 are fixedly connected with a connecting rod 31. The lifting rod 3 is fixedly connected to the end of the connecting rod 31 away from the positioning block 24. The positioning screw 25 is rotatably connected to the inner top wall and the inner bottom wall of the support rod 2. The positioning screw 25 is threadedly connected to the middle part of the positioning block 24. The electric motor 22 is fixedly installed on the upper end of the support rod 2, and the output end of the electric motor 22 is connected to the upper end of the positioning screw 25. The ends are fixedly connected, a limiting groove 32 is provided near the lower end of the lifting rod 3, the buffer rod 34 is slidably connected to the limiting groove 32, the lower end of the buffer rod 34 is fixedly connected to the buffer gasket 35, and the side wall of the limiting groove 32 is provided with two groups of symmetrically distributed adjustment grooves 33, the upper end of the buffer rod 34 is fixedly connected with two groups of adjustment blocks 36, the adjustment blocks 36 are slidably connected to the adjustment groove 33, and a limiting spring 37 is provided inside the limiting groove 32, and the upper and lower ends of the limiting spring 37 are respectively abutted against the inner top wall of the limiting groove 32 and the upper end of the buffer rod 34.

[0042] It should be added that during the adjustment of the lifting rod 3, the electric motor 22 is remotely controlled through remote sensing, and the output end of the electric motor 22 rotates clockwise to drive the positioning screw 25 to rotate clockwise. During the rotation of the positioning screw 25, the positioning block 24 is driven to slide downward inside the positioning groove 23, and then the lifting rods 3 on the front and rear sides move downward, and the buffer gasket 35 is moved to the lower side of the surveying and mapping gimbal 43 to support the drone body 1 and the surveying and mapping gimbal 43. When the drone is landing, the buffer gasket 35 touches the ground first. When the drone body 1 stops completely, the limit spring 37 will further buffer the impact force generated during the landing process, effectively improving the safety of the surveying and mapping gimbal 43 and the drone body 1. At the same time, when the equipment is transported and carried, the output end of the electric motor 22 rotates in the opposite direction, and then the lifting rod 3 moves upward to the front and rear sides of the support rod 2. Then the two sets of support rods 2 are disassembled and stacked together, effectively reducing the space occupied by the buffer mechanism, making it easier for the equipment to be transported and carried.

[0043] The working principle of the present invention is as follows: by setting the buffer mechanism into two groups, after the buffer mechanism is disassembled, it can be stacked together for carrying and transportation, reducing its footprint; at the same time, by moving the lifting rod 3 upward to both sides of the support rod 2, the footprint of the buffer mechanism is further reduced, greatly improving its convenience in transportation and carrying; at the same time, during use, after the lifting rod 3 is raised, the buffer gasket 35 will be raised to the upper side of the surveying and mapping platform 43, avoiding obstruction to the surveying and mapping platform 43 and improving the surveying and mapping accuracy.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
