Description

Technical Field

[0001] The present invention belongs to the technical field of data acquisition, and specifically relates to a device for collecting surveying and mapping geographical information data. Background Art

[0002] A surveying instrument is a device designed and manufactured for data acquisition, processing, and output in surveying operations. In the process of using existing surveying equipment, it is mostly used in combination with a tripod. The tripod provides a horizontal working environment for the surveying instrument. However, in the actual application process, the tripod needs to be aligned in different environments, so that a large amount of time is required to level the surveying instrument in the early stage of use. At the same time, the existing surveying instrument is not easy to adjust the surveying direction, which has certain limitations; when surveying some rugged places, not only the surveying instrument and the support are not easy to carry, but also the surveying instrument needs to be protected additionally during the carrying process, thus increasing the weight of the surveying instrument during carrying.

[0003] In order to solve the above problems, through retrieval, there is a publicly disclosed patent (application number: CN202211470893.7) for a surveying equipment for collecting surveying and mapping geographical information. It is proposed in the text that "it includes a support base, a mounting column is movably installed on the side wall of the support base, a leg is fixedly installed on the side wall of the mounting column, and the side wall of the mounting column is in sliding contact with the side wall of the support base. A connecting handle is fixedly installed on the side wall of the support base, the other end of the connecting handle is fixedly installed with a support top seat located above the support base, and an alignment ball is movably installed at the end of the support top seat, and the alignment ball is a sphere".

[0004] When the above-mentioned acquisition device is in use, a guide plate is arranged in the alignment ball, and it moves along with the baffle according to the guide groove, ensuring that during the alignment process of the surveying instrument body, the sealing column is pulled down by the baffle, so that the air flow in the pressure storage cavity slowly exits, enabling the surveying instrument body to have enough time for positioning. Then, after the positioning is completed, the adjustment rod is pressed against the sliding sleeve, restricting the alignment ball to only rotate, and finally achieving the purpose of being easy to position and fix and freely adjust the rotation. However, during the carrying process, although the surveying instrument body can be protected to a certain extent by the baffle and the leg, the protection range is limited, and the surveying instrument body cannot be comprehensively protected. Moreover, since the cost of the surveying instrument equipment is relatively high, it needs to be placed separately for protection when not in use, and then installed and disassembled again when in use, which is rather troublesome in operation and affects the work efficiency. Therefore, a device for collecting surveying and mapping geographical information data is proposed. Summary of the Invention

[0043] Working principle or structural principle: When the surveying instrument body 1 needs to be used for geographical information surveying, first press down the protective cover 3. The protective cover 3 will push the wedge plate 308 to drive the sliding rod 307 to slide on the fixing member 306 and compress the first spring 309. At this time, the protective cover 3 pushes the top plate 403 and the ejector rod 402 to move downward and compress the second spring 404 until the bottom of the protective cover 3 fits against the bottom of the slot 303. At this time, the insertion plate 305 is located within the horizontal position of the limiting groove 304, the wedge plate 308 is located above the clamping groove 302, and the insertion plate 305 is located below the baffle 406. Then rotate the protective cover 3 until the insertion plate 305 is completely located within the horizontal position of the limiting groove 304 and the insertion plate 305 moves below the baffle 406. At this time, the side of the groove 301 away from the clamping groove 302 corresponds to the side of the side groove 601 away from the fixing member 306. Then the protective cover 3 can be lifted upward, pushing the baffle 406 to move into the mounting plate 2 and compress the third spring 405 until the baffle 406 is pushed to the uppermost position. At this time, the clamping groove 302 is located above the wedge plate 308. Subsequently, rotate in the reverse direction to make the insertion plate 305 located within the vertical position of the limiting groove 304, and then the protective cover 3 can be removed from the slot 303. After removing the slot 303, the first spring 309 pushes the wedge plate 308 to reset and no longer fit against the bottom of the limiting plate 606. Then the support rod 603 can be rotated to adjust the angle of the support rod 603. Manually rotate the bolt 501 to drive the adjusting plate 502 to retract into the sliding groove 504. Then under the action of gravity, the adjusting rod 604 and the fixing cone 605 slide downward from the support rod 603. At this time, the bolt 501 slides within the vertical groove 505 and is adjusted to a suitable position so that the adjusting plate 502 corresponds to the position of a set of positioning grooves 506. Manually rotate the bolt 501 to push the adjusting plate 502 to slide outward through the positioning groove 506, and then the position of the adjusting rod 604 can be fixed. The positions of the three groups of adjusting rods 604 are adjusted in sequence, and the fixing cone 605 is inserted into the ground for fixation. Finally, the surveying instrument body 1 is adjusted to a horizontal state, and then geographical information can be collected. After the surveying is completed, rotate the three support rods 603 to a state perpendicular to the ground, and retract the adjusting rods 604 into the support rods 603 so that the adjusting plate 502 is inserted into the uppermost set of positioning grooves 506. Subsequently, place the protective cover 3 into the slot 303 so that the insertion plate 305 is inserted into the limiting groove 304. When one side of the groove 301 fits against the wedge plate 308, it will push the wedge plate 308 to move below the limiting plate 606, compressing the first spring 309. And when the clamping groove 302 is parallel to the wedge plate 308, under the action of the first spring 309, one end of the wedge plate 308 is pushed into the clamping groove 302, and the other end of the wedge plate 308 is located against the bottom of the limiting plate 606. At the same time, the insertion plate 305 fits against the vertical position of the baffle 406, thereby fixing the support rod 603. At this time, under the action of the second spring 404, the top plate 403 fits against the bottom of the protective cover 3.And provide an upward supporting force, thereby fixing the protective cover 3. When the surveying instrument body 1 needs to be repaired and maintained, only two sets of nuts 703 need to be removed from the threaded posts 702, and the surveying instrument body 1 can be directly taken out from the placement groove 201.,

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
