Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping devices, and in particular to a geographic information acquisition and surveying and mapping device. Background Art

[0002] Geographic information refers to information related to spatial geographical distribution, which represents the general term of data, quality, distribution characteristics, connections and laws inherent in surface objects and the environment, including numbers, texts, graphics, images, etc. In urban and rural construction, land resource utilization, environmental protection and other work, land measurement and mapping of various maps must be carried out for planning and management. In geological exploration, mineral development, water conservancy, transportation and other construction, control surveying, mine surveying, route surveying and topographic map drawing must be carried out for geological general survey and the design and construction of various buildings. Measuring these environmental data is necessarily inseparable from surveying instruments.

[0003] An existing geographic information acquisition device, a portable geographic information surveying and mapping instrument (Publication No.: CN111707247B), has at least the following drawbacks: Through the coordinated use of a Bluetooth module, a wireless transmission module, and a controller module, the above patent connects a mobile display device to the surveying and mapping instrument through a network. The geographic information data measured by the surveying and mapping instrument can be processed and fed back to the mobile device in real time, enabling the operator to perform data operations on the mobile device without the operator being next to the surveying and mapping instrument for data surveying and mapping, and the data display is more intuitive, greatly facilitating the surveying and mapping work of geographic information; Since the components of the surveying and mapping instrument in the above patent are directly exposed and installed on the support structure, when transporting the components of the surveying and mapping instrument, the components of the surveying and mapping instrument are prone to collision and damage. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and to propose a geographic information acquisition and surveying and mapping device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A geographic information acquisition and surveying and mapping device includes a protective cylinder and a camera. A support disk that can slide up and down is installed on the inner wall of the protective cylinder. A rotating table is fixedly installed on the upper surface of the support disk. The camera is fixedly installed at the top of the rotating table. A top cover that matches the protective cylinder is fixedly installed at the top of the camera. A lifting mechanism is installed between the protective cylinder and the support disk. A cleaning mechanism for cleaning the lens of the camera is installed on the top of the support disk.

[0006] As a further aspect of the present invention, the lifting mechanism includes a plurality of T-shaped guide rails fixedly installed at the bottom end of the protective cylinder in a circumferentially uniform manner. A moving block is slidably installed on the outer surface of the T-shaped guide rail. An inclined groove is formed through the outer surface of the moving block. A plurality of connecting rods are fixedly installed at the bottom end of the support disk in a circumferentially uniform manner. A moving column matching the inclined groove is fixedly installed at the bottom end of the connecting rod. The moving column is slidably installed on the inner wall of the inclined groove.

[0007] As a further aspect of the present invention, the cleaning mechanism includes a rotating ring rotatably installed on the upper surface of the support disk. Two mounting blocks are symmetrically and fixedly installed on the upper surface of the rotating ring. A C-shaped frame is rotatably installed between the two mounting blocks through a torsion rotating shaft. A brush disk is rotatably installed on the outer surface of the C-shaped frame close to the camera side. The brush disk and the lens of the camera are arranged at the same horizontal height. A rotating assembly is installed between the rotating ring and the protective cylinder. A transmission assembly is installed between the brush disk and the support disk.

[0008] As a further aspect of the present invention, the rotating assembly includes a spiral groove formed on the inner wall of the protective cylinder. A guide post matching the spiral groove is fixedly installed on the outer circumference of the rotating ring. The guide post is slidably installed on the inner wall of the spiral groove. A synchronization assembly is installed between the rotating table and the rotating ring.

[0009] As a further aspect of the present invention, the transmission assembly includes a conical friction wheel rotatably installed on the outer surface of the C-shaped frame close to the camera side. A friction ring matching the conical friction wheel is fixedly installed on the upper surface of the support disk. The outer circumference of the conical friction wheel intermittently abuts against the inner side of the friction ring.

[0010] As a further aspect of the present invention, the synchronization assembly includes two dial plates fixedly installed on the outer circumference of the rotating table. The two mounting blocks are installed between the two dial plates.

[0011] As a further aspect of the present invention, belt pulleys are fixedly installed at the rotation centers of the brush disk and the conical friction wheel. A belt is sleeved on the outer surfaces of the two belt pulleys.

[0012] As a further aspect of the present invention, a plurality of telescopic support rods are rotatably installed on the outer circumference of the protective cylinder close to its top end. A moving assembly is installed between the telescopic support rod and the moving block. The moving assembly includes a guide frame fixedly installed on the outer surface of the moving block close to the telescopic support rod side. A dial post is fixedly installed on the outer surface of the telescopic support rod. The dial post is slidably installed on the inner wall of the guide frame.

[0013] The beneficial effects of the present invention are: 1. After the camera completes the surveying and mapping of the geographical environment, multiple telescopic support rods are closed inward, so that the dial posts installed on the telescopic support rods push the moving blocks inward through the guide frames, and the inclined grooves opened on the moving blocks pull the entire support plate downward through the moving columns and connecting rods, enabling the camera installed on the support plate to retract into the protective cylinder. At the same time, the top cover installed at the top of the camera can block the top of the protective cylinder, thereby achieving the protective effect on the camera during transportation and preventing the camera from being damaged due to collision; 2. When the support plate drives the rotating ring to move up and down, the guide posts installed on the outer periphery of the rotating ring will move along the inner wall of the spiral groove opened on the inner wall of the protective cylinder, enabling the rotating ring to drive the brush disk and the rotating table to move up and down and rotate inside the protective cylinder through the mounting block and the dial plate; when the C-shaped frame moves inside the protective cylinder, the conical friction wheel will roll on the friction ring, enabling the conical friction wheel to drive the brush disk to rotate by itself through the belt pulley and the belt, so that the brush disk can clean the surface of the camera lens and prevent the dust adhered to the lens surface from affecting the shooting and surveying effect of the camera on the surrounding geographical environment.

Specific embodiments

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0017] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail the present invention with reference to the drawings and in combination with the embodiments.

[0018] Refer to the attached Figure 1 - attached Figure 10, A geographic information acquisition and mapping device, including a protective cylinder 1 and a camera 4. A control panel is installed on the outer side of the camera 4, and the camera 4 can be controlled through the control panel to realize the shooting and mapping operation of the surrounding ground environment by the camera 4. In this solution, the mapping process of the camera 4 adopts the prior art used in a comparative document, a portable geographic information mapping instrument for geographic information acquisition device (Publication No.: CN111707247B), and will not be elaborated here. A slidable support plate 2 is installed on the inner wall of the protective cylinder 1. A rotating platform 3 is fixedly installed on the upper surface of the support plate 2. The camera 4 is fixedly installed at the top of the rotating platform 3. A top cover 5 matching the protective cylinder 1 is fixedly installed at the top of the camera 4. A lifting mechanism is installed between the protective cylinder 1 and the support plate 2. A cleaning mechanism for cleaning the lens of the camera 4 is installed on the top of the support plate 2. A plurality of telescopic support rods 24 are evenly and rotatably installed on the outer circumference of the protective cylinder 1 near its top. The telescopic support rod 24 is composed of a threaded pipe and a threaded rod, one end of which is rotatably installed on the outer side of the protective cylinder 1. The threaded rod is threadedly connected to the inner wall of the threaded pipe. A moving component is installed between the telescopic support rod 24 and the moving block 7. The moving component includes a guide frame 22 fixedly installed on the outer surface of the moving block 7 near the telescopic support rod 24. A dial post 23 is fixedly installed on the outer surface of the telescopic support rod 24. The dial post 23 is slidably installed on the inner wall of the guide frame 22. The lifting mechanism includes a plurality of T-shaped guide rails 6 evenly and fixedly installed at the bottom end of the protective cylinder 1 in the circumferential direction. The outer surface of the T-shaped guide rail 6 is slidably installed with a moving block 7. An inclined slot 8 is penetrated and opened on the outer surface of the moving block 7. A plurality of connecting rods 9 are evenly and fixedly installed at the bottom end of the support plate 2 in the circumferential direction. A moving column 10 matching the inclined slot 8 is fixedly installed at the bottom end of the connecting rod 9. The moving column 10 is slidably installed on the inner wall of the inclined slot 8.

[0019] When the telescopic support rod 24 is pulled outward, the dial post 23 installed on the telescopic support rod 24 will pull the moving block 7 to move outward synchronously through the guide frame 22, so that the inclined slot 8 opened on the moving block 7 can push the entire support plate 2 upward through the moving column 10 and the connecting rod 9, so that the camera 4 installed on the support plate 2 can extend out of the top of the protective cylinder 1, so as to perform camera mapping on the surrounding geographical environment through the camera 4. After the camera 4 completes the mapping of the geographical environment, the plurality of telescopic support rods 24 are closed inward, so that the dial post 23 installed on the telescopic support rod 24 pushes the moving block 7 to move inward through the guide frame 22, so that the inclined slot 8 opened on the moving block 7 pulls the entire support plate 2 downward through the moving column 10 and the connecting rod 9, so that the camera 4 installed on the support plate 2 can retract into the protective cylinder 1. At the same time, the top cover 5 installed at the top of the camera 4 can block the top of the protective cylinder 1, so as to achieve the protection effect of the camera 4 during transportation and avoid damage to the camera 4 due to collision.

[0020] In this embodiment, the cleaning mechanism includes a rotating ring 11 rotatably mounted on the upper surface of the support disk 2. Two mounting blocks 14 are symmetrically and fixedly mounted on the upper surface of the rotating ring 11. A C-shaped frame 15 is rotatably mounted between the two mounting blocks 14 through a torsion rotating shaft. A brush disk 16 is rotatably mounted on the outer surface of the C-shaped frame 15 near the camera 4. The brush disk 16 and the lens of the camera 4 are arranged at the same horizontal height. A rotating assembly is installed between the rotating ring 11 and the protective cylinder 1, and a transmission assembly is installed between the brush disk 16 and the support disk 2. The rotating assembly includes a spiral groove 13 formed on the inner wall of the protective cylinder 1. A guide post 12 matching the spiral groove 13 is fixedly mounted on the outer circumference of the rotating ring 11. The guide post 12 is slidably mounted on the inner wall of the spiral groove 13. A synchronous assembly is installed between the rotating table 3 and the rotating ring 11. The transmission assembly includes a conical friction wheel 17 rotatably mounted on the outer surface of the C-shaped frame 15 near the camera 4. A friction ring 18 matching the conical friction wheel 17 is fixedly mounted on the upper surface of the support disk 2. The outer circumference of the conical friction wheel 17 intermittently abuts against the inner side of the friction ring 18. The synchronous assembly includes two dial plates 21 fixedly mounted on the outer circumference of the rotating table 3. The two mounting blocks 14 are installed between the two dial plates 21. Belt pulleys 19 are fixedly mounted at the rotation centers of the brush disk 16 and the conical friction wheel 17 respectively. A belt 20 is sleeved on the outer surfaces of the two belt pulleys 19.

[0021] When the support disk 2 drives the rotating ring 11 to move up and down, the guide post 12 installed on the outer circumference of the rotating ring 11 will move on the inner wall of the spiral groove 13 formed on the inner wall of the protective cylinder 1, so that the rotating ring 11 can drive the brush disk 16 and the rotating table 3 as a whole to lift and rotate inside the protective cylinder 1 through the mounting blocks 14 and the dial plates 21; when the C-shaped frame 15 moves inside the protective cylinder 1, the conical friction wheel 17 will roll on the friction ring 18, so that the conical friction wheel 17 can drive the brush disk 16 to rotate through the belt pulley 19 and the belt 20, so that the brush disk 16 can clean the surface of the lens of the camera 4, avoiding the dust adhering to the lens surface from affecting the shooting and mapping effect of the camera 4 on the surrounding geographical environment.

[0022] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: when in use, the device is carried to the site to be surveyed and mapped, and multiple telescopic support rods 24 are pulled outward, so that the multiple telescopic support rods 24 are unfolded and supported on the ground, realizing the overall support effect on the protective cylinder 1, so as to subsequently conduct camera shooting and mapping on the surrounding geographical environment through the camera 4; When the telescopic support rod 24 is toggled outward, the dial post 23 installed on the telescopic support rod 24 will pull the moving block 7 to move outward synchronously through the guide frame 22, so that the inclined groove 8 formed on the moving block 7 can push the support disk 2 upward as a whole through the moving column 10 and the connecting rod 9, so that the camera 4 installed on the support disk 2 can extend out of the top of the protective cylinder 1, so as to conduct camera shooting and mapping on the surrounding geographical environment through the camera 4; After the camera 4 has completed the mapping of the geographical environment, multiple telescopic support rods 24 are closed inward, so that the dial posts 23 installed on the telescopic support rods 24 push the moving block 7 inward through the guide frame 22, and the inclined slots 8 opened on the moving block 7 pull the support disk 2 downward as a whole through the moving posts 10 and the connecting rod 9, so that the camera 4 installed on the support disk 2 can retract into the protective cylinder 1. At the same time, the top cover 5 installed at the top of the camera 4 can block the top of the protective cylinder 1, so as to achieve the protection effect of the camera 4 during transportation and avoid damage to the camera 4 caused by collision; When the support disk 2 drives the rotating ring 11 to move up and down, the guide posts 12 installed on the outer periphery of the rotating ring 11 will move on the inner wall of the spiral groove 13 opened on the inner wall of the protective cylinder 1, so that the rotating ring 11 can drive the brush disk 16 and the rotating table 3 to move up and down and rotate inside the protective cylinder 1 through the mounting block 14 and the dial plate 21; when the C-shaped frame 15 moves inside the protective cylinder 1, the conical friction wheel 17 will roll on the friction ring 18, so that the conical friction wheel 17 can drive the brush disk 16 to rotate by itself through the belt pulley 19 and the belt 20, so that the brush disk 16 can clean the lens surface of the camera 4 and avoid the dust adhered to the lens surface from affecting the shooting and mapping effect of the camera 4 on the surrounding geographical environment; When the C-shaped frame 15 is located outside the protective cylinder 1, the whole C-shaped frame 15 will turn outward under the action of the torsion rotating shaft, so that the brush disk 16 no longer blocks the lens of the camera 4, ensuring the shooting and mapping effect of the camera 4 on the surrounding geographical environment.

[0023] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. The narrative mode of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
