[0023] Example 1

[0024] like Figures 1-6 As shown in the figure, the surveying instrument support frame proposed in this embodiment includes a mounting cover, a fastening component, and a mounting base.

[0025] The mounting cover includes a rotating cover 7, a sliding cover 8, and a lens protection assembly. The rotating cover 7 has a first opening 701, and the sliding cover 8 has a second opening 801. Semi-annular seals are provided at both the first opening 701 and the second opening 801. The lens protection assembly includes a first bracket 13 mounted on the sliding cover 8, a light-transmitting lens cover rotatably mounted on the first bracket 13, and a first torsion spring 14 that twists the light-transmitting lens cover towards the annular structure. When the sliding cover 8 is pulled outwards, the user places the surveying camera inside the rotating cover 7, and then closes the sliding cover 8 towards the rotating cover 7. When the sliding cover 8 and the rotating cover 7 are closed, the two seals close into an annular structure. Under the action of the first torsion spring 14, the end of the light-transmitting lens cover abuts against the annular structure for sealing, thus blocking the surveying camera lens while ensuring light transmission.

[0026] The fastening components hold the surveying instrument firmly inside the mounting cover to prevent the surveying camera from shaking during surveying and to ensure surveying quality.

[0027] like Figure 1 and Figure 2As shown, the mounting base includes, from top to bottom, a mounting plate 1, a rubber head 2, a mounting frame 3, and a rotating frame 4; a first motor 5 mounted on the mounting frame 3 and driving the rotating frame 4 to rotate; and a second motor 6 driving the rotating cover 7 to rotate. The second motor 6 is mounted on the rotating frame 4. The mounting plate 1 allows the support frame to be installed onto the bottom of the mapping drone. The first motor 5 is used to adjust the orientation of the rotating frame 4, and the second motor 6 is used to adjust the orientation of the rotating cover 7, thereby comprehensively adjusting the orientation of the mapping camera inside the mounting cover to perform mapping in the required orientation.

[0028] The rotating cover 7 has an insert plate portion 71, and the sliding cover 8 has a slot 81 for inserting the insert plate portion 71 in a straight direction. The insert plate portion 71 is inserted into the slot 81, and the mounting cover is opened by sliding the sliding cover 8 away from the rotating cover 7 to facilitate the insertion of the surveying camera. The mounting cover is closed by sliding the sliding cover 8 toward the rotating cover 7. Before opening the mounting cover, the lens cover needs to be rotated outwards. After closing the mounting cover, the lens cover is released, and the lens cover is rotated inwards to abut against the seal using the torque of the first torsion spring 14.

[0029] This embodiment can shield and protect the surveying camera while ensuring light transmission through the lens, thus not affecting surveying. It also prevents the camera from being wetted by rain, snow, or fog, and avoids direct impact. When the sliding cover 8 slides outward, sufficient space is provided to house the surveying camera inside the rotating cover 7. The sliding cover 8 and rotating cover 7 are then closed, covering the lens of the surveying camera. Fastening components secure the surveying camera inside the mounting cover, ensuring surveying quality and providing effective protection for the camera.

[0030] Example 2

[0031] like Figures 1-6 As shown in this embodiment, a surveying instrument support frame is proposed. Compared to Embodiment 1, in this embodiment, the sealing element includes a semi-annular fixing ring 9 and a semi-annular sealing gasket 10. The two fixing rings 9 are respectively disposed on the rotating cover 7 and the sliding cover 8, and the sealing gasket 10 is disposed on the fixing ring 9. The openings on the rotating cover 7 and the sliding cover 8 are both semi-annular openings, corresponding to the two semi-annular sealing elements respectively. The surveying camera lens passes through the opening. After the surveying camera is installed inside the mounting cover, sealing is achieved by the contact between the light-transmitting lens cover and the sealing gasket 10.

[0032] The light-transmitting lens cover includes a connecting cylinder 11 rotatably mounted on the first bracket 13 and a transparent cover 12 disposed at the outer end of the connecting cylinder 11. The connecting cylinder 11 is used for the rotatable installation of the light-transmitting lens cover, and the transparent cover 12 is used to ensure light transmission. The transparent cover 12 can be made of glass. The sealing gasket 10 has a groove for the other end of the connecting cylinder 11 to be inserted into, and the connecting cylinder 11 is inserted into the groove, resulting in a good sealing effect. The outer circumferential surface of the connecting cylinder 11 has coaxially distributed annular guide grooves 111. The guide grooves 111 are close to the sealing element. When rainwater falls here, it will flow down along the guide grooves 111 and fall down, and is less likely to enter the inner side of the mounting cover.

[0033] In this embodiment, the lens cover is designed as a split structure, which ensures both light transmission and reliable rotational installation.

[0034] Example 3

[0035] like Figures 1-6 As shown in this embodiment, a surveying instrument support frame is proposed. Compared to Embodiment 1, this embodiment has multiple sets of fastening components arranged side by side, including a connecting platform 19 disposed on the back of the sliding cover 8 and a threaded knob 20 threadedly connected to the connecting platform 19. The rotating cover 7 has a first through hole through which the threaded knob 20 passes, and the sliding cover 8 has a second through hole through which the threaded knob 20 passes. After the sliding cover 8 and the rotating cover 7 are aligned, the threaded knob 20 is screwed inward, passing through the first and second through holes, and its end abuts against the back of the surveying camera, thus securing the surveying camera within the mounting cover and improving surveying stability.

[0036] The surveying instrument support frame also includes an anti-detachment component, which includes a baffle 18 on the back of the sliding cover 8, a second bracket 15 on the back of the rotating cover 7, a clamp 16 rotatably mounted on the second bracket 15, and a second torsion spring 17 that twists the clamp 16 to engage with the baffle 18. After the sliding cover 8 is slid into place with the rotating cover 7, the second torsion spring 17 will cause the clamp 16 to twist, blocking the end of the clamp 16 against one side of the baffle 18, preventing the sliding cover 8 from sliding off in the opposite direction.

[0037] This embodiment improves the stability of the surveying camera during UAV flight surveying by tightening and limiting the surveying camera, and uses anti-detachment components to prevent the sliding cover 8 from falling off.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
