Description

Technical Field

[0001] The present invention relates to the technical field of geographic information measuring instruments, and in particular to a surveying and mapping device and method for collecting geographic information. Background Art

[0002] Surveying and mapping instruments are widely used in geographic information collection, mainly including the following aspects:

[0003] Data collection: Various parameters of geographic locations can be accurately measured, such as angles, distances, heights, etc. By using surveying instruments such as total stations, levels, and GPS, a large amount of geographic data can be quickly acquired. In some areas that are difficult to reach or have harsh environments, the role of surveying instruments is more obvious. For example, GPS surveying instruments are used to determine the latitude and longitude coordinates, elevation, speed and other information of the measuring point; total stations can measure angles and distances with high precision; levels are used to measure the height difference between two points;

[0004] Land survey: Providing important support for land survey, the geographic information system can provide land-related information, such as the location of land, property boundaries, area, type, ownership, price, tax policy, etc., and plays a key role in land registration, area statistics, resource evaluation and land use. Accurate geographic information data can fully meet the cadastral data operation, provide convenience for user query, and realize the accuracy and science of the whole process of land survey;

[0005] Map drawing: It is easy to draw high-quality digital maps. In the geographic information system, data is stored through layering technology, and the map is composed of several layers. Users only need to search for the map data of the corresponding layer to quickly obtain the required information. In addition, spatial analysis of geographic data can be performed, and the analysis results can be output on the computer screen or plotter, which is convenient for users to conduct research in combination with geographic data.

[0006] During the surveying and mapping process, the surveying instrument is supported by a tripod. After the measurement, in order to avoid repeated adjustment and installation when the surveying instrument is used again, the surveying instrument is usually stored and placed together with the tripod. When the surveying instrument is directly stored and placed on the tripod, the surveying instrument is exposed, which increases the probability of bumping and damage to the surveying instrument.

[0023] S1: During the surveying and mapping process, the surveying instrument is installed above the support rod of the tripod. During the installation process, the surveying instrument is leveled and aligned by adjusting the components, so that the surveying instrument can collect geographic information more accurately.

[0024] S2: After the surveying and mapping of the surveying and mapping instrument is completed, in order to avoid repeated adjustment and installation when the surveying and mapping instrument is used again, the connection between the surveying and mapping instrument and the tripod bracket is maintained, and in order to prevent the surveying and mapping instrument in a naked state on the tripod bracket from being damaged during the movement and storage process, the protective tube is driven to move upward on the support rod through the cooperation between the lifting assembly and the first guide assembly;

[0025] S3: During the movement of the protective cylinder, the piston cylinder is driven to move synchronously through the connecting transmission of the telescopic assembly. During the movement of the piston cylinder, the upper end of the piston cylinder is abutted against the push plate. The push plate acts as a limit to the piston cylinder and the protective cylinder continues to move upward under force, so that relative movement occurs between the protective cylinder and the piston cylinder. During the relative movement, the circular plate inside the protective cylinder is pushed to move relative to the piston cylinder under force.

[0026] S4: Through the relative movement of the circular plate inside the piston cylinder, part of the gas inside the piston cylinder is squeezed and transported to the inside of the annular mounting frame through the hose, and the inside of the annular mounting frame is inflated. During the inflation process, the annular airbag is forced to expand due to the pressure inside the annular mounting frame. With the upward movement of the protective cylinder and the expansion of the annular airbag after being forced, the annular airbag is wrapped and tightly pressed against the outside of the surveying instrument, so as to prevent the surveying instrument from being bumped and damaged in the state of being exposed on the tripod bracket;

[0027] S5: During the relative movement between the protective cylinder and the piston cylinder, the protective cylinder pushes the transmission plate to move inside the slot. During the movement, the pull rope is pulled and pushed by the connection transmission effect between the transmission hole on the transmission plate and the pull rope and the connection and fixing effect between one end of the pull rope and one side of the connecting plate. During the pulling and pushing process, the transmission block is pulled to move downward by the auxiliary support effect of the first support assembly and the second support assembly.

[0028] S6: During the downward movement of the transmission block, the rack is driven to move downward synchronously. During the movement of the rack, the rotating shaft is driven to rotate through the mutual meshing transmission between the rack and the gear;

[0029] S7: During the rotation of the shaft, the connecting transmission action of the connecting block drives the fan-shaped cover plate to be forced to flip toward the upper end of the protective tube and resist each other. The protective tube is covered and sealed by the flipping of the two sets of fan-shaped cover plates and the resistance against the upper end of the protective tube. By covering and sealing the protective tube, the probability of the surveying instrument inside the protective tube being affected by moisture and dust accumulation is reduced, further facilitating the protection and use of the surveying instrument.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] After the surveying and mapping instrument is completed, in order to prevent the surveying and mapping instrument in an exposed state on the tripod from being damaged during the movement and storage, the protective tube is driven to move upward on the support rod through the cooperation between the lifting assembly and the first guide assembly. During the movement of the protective tube, the annular airbag can be forced to expand, so that the annular airbag can wrap and tightly resist the outside of the surveying and mapping instrument, and the protective tube can be covered and sealed, so as to achieve the effect of preventing the surveying and mapping instrument from being damaged by bumps and moisture-proof and dust-proof.

[0079] S7: During the rotation of the rotating shaft 1002, the connecting transmission action of the connecting block 1003 drives the fan-shaped cover plate 9 to be forced to flip toward the upper end of the protective tube 2 and resist each other. Through the flipping of the two groups of fan-shaped cover plates 9 and the resistance against the upper end of the protective tube 2, the protective tube 2 is covered and sealed. By covering and sealing the protective tube 2, the probability of the surveying instrument 102 inside the protective tube 2 being damp and dusty is reduced, which further facilitates the protective use of the surveying instrument 102.

10. A surveying and mapping method for collecting geographic information, which refers to a surveying and mapping device for collecting geographic information as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1: During the surveying and mapping process, the surveying and mapping instrument (102) is installed above the support rod (103) of the tripod support (101). During the installation process, the surveying and mapping instrument (102) is leveled and aligned by the adjustment component (104), so that the surveying and mapping instrument (102) can collect geographic information more accurately. S2: After the surveying and mapping of the surveying and mapping instrument (102) is completed, in order to avoid repeated adjustment and installation of the surveying and mapping instrument (102) when it is used again, the connection between the surveying and mapping instrument (102) and the tripod support (101) is maintained, and in order to avoid the surveying and mapping instrument (102) in a naked state on the tripod support (101) from being damaged during the movement and storage process, the protective tube (2) is driven to move upward on the support rod (103) through the cooperation between the lifting assembly and the first guide assembly; S3: During the movement of the protective cylinder (2), the piston cylinder (703) is driven to move synchronously through the connecting transmission action of the telescopic assembly. During the movement of the piston cylinder (703), the upper end of the piston cylinder (703) is abutted against the push plate (705). The push plate (705) acts as a limit to the piston cylinder (703) and the protective cylinder (2) continues to move upward under force, so that relative movement occurs between the protective cylinder (2) and the piston cylinder (703). During the relative movement, the circular plate (701) inside the protective cylinder (2) is pushed to move relative to the inside of the piston cylinder (703) under force. S4: by the relative movement of the circular plate (701) inside the piston cylinder (703), part of the gas inside the piston cylinder (703) is squeezed and transported to the inside of the annular mounting frame (601) through the hose (704), and the inside of the annular mounting frame (601) is inflated. During the inflation process, the annular airbag (602) is forced to expand due to the pressure inside the annular mounting frame (601). With the upward movement of the protective cylinder (2) and the expansion of the annular airbag (602) after being forced, the annular airbag (602) is wrapped and tightly pressed against the outside of the surveying instrument (102), so as to prevent the surveying instrument (102) from being bumped and damaged by collision when it is exposed on the tripod support (101); S5: During the relative movement between the protective cylinder (2) and the piston cylinder (703), the protective cylinder (2) pushes the transmission plate (1402) to move inside the slot (1401). During the movement, the pull rope (1301) is pulled and pushed by the connection and transmission effect between the transmission hole (1403) on the transmission plate (1402) and the pull rope (1301) and the connection and fixing effect between one end of the pull rope (1301) and one side of the connecting plate (1303). During the pulling and pushing process, the transmission block (1302) is pulled to move downward by the auxiliary support effect of the first support assembly and the second support assembly. S6: During the downward movement of the transmission block (1302), the rack (1102) is driven to move downward synchronously. During the movement of the rack (1102), the rotating shaft (1002) is driven to rotate through the mutual meshing transmission between the rack (1102) and the gear (1101); S7: During the rotation of the rotating shaft (1002), the connecting transmission action of the connecting block (1003) drives the fan-shaped cover plate (9) to be forced to flip toward the upper end of the protective tube (2) and to abut against each other. By flipping the two sets of fan-shaped cover plates (9) and abutting against the upper end of the protective tube (2), the protective tube (2) is covered and sealed. By covering and sealing the protective tube (2), the probability of the surveying instrument (102) inside the protective tube (2) being damp or dusty is reduced, thereby further facilitating the protective use of the surveying instrument (102).
