Description

Technical Field

[0001] This utility model relates to the field of geographic information data acquisition technology, and specifically to a geographic information system data acquisition device. Background Technology

[0002] Geographic information data is information with location tags. Its core function is to place information in a spatial context to facilitate positioning, visualization, querying, and spatial analysis, thereby revealing the spatial distribution patterns, interrelationships, and development trends of things, providing strong support for understanding the surrounding world, solving spatially related problems, and making more informed decisions.

[0003] In existing related technologies, for example, Chinese patent document with publication number CN212905470U discloses a geographic information system data acquisition device. Through structural design, it can achieve heat dissipation of the acquisition device through a heat dissipation motor when acquiring GPS data, thereby improving its service life and reducing power consumption.

[0004] However, in the field, especially in soft sandy areas (such as desertified land or desert), the soil is loose and lacks support. When it encounters a large air flow, it is very easy to shake or shift, which will affect the accuracy of the measurement and the reliability of the data obtained. Utility Model Content

[0011] Optionally, the insertion plate further includes two force transmission plates, which are respectively connected to two oppositely arranged connecting plates; the driving member is provided in two parts, which are respectively connected to the two force transmission plates in a one-to-one correspondence, so as to drive the insertion plate to move in the vertical direction.

[0012] Optionally, in the direction of the line connecting the two oppositely arranged first plates, the ratio of the projected length L1 of the connecting plate to the projected length L2 of the insert plate satisfies: 1 / 10 ≤ L1 / L2 ≤ 1 / 2.

[0013] Optionally, the through hole includes two symmetrically arranged second through holes, the second through holes having a U-shaped structure and being inclined, and the distance between the bottom of the second through hole and the central axis of the base plate is less than the distance between the top of the second through hole and the central axis of the base plate; the insertion plate includes two second plate bodies adapted to the second through holes.

[0034] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] like Figures 1 to 7As shown, this embodiment provides a geographic information system data acquisition device 100, including a base plate 101, a data acquisition instrument body 102 mounted on the base plate 101 for acquiring geographic information data, and casters 103 mounted on the base plate 101. The geographic information system data acquisition device 100 also includes a through hole 1 and a fixing component 2. The through hole 1 is formed on the base plate 101; the fixing component 2 includes a driving member 21 and an insertion plate 22. The driving member 21 is mounted on the base plate 101, and the output end of the driving member 21 is connected to the insertion plate 22 to drive the insertion plate 22 through the through hole 1. The insertion plate 22 has a ring-shaped structure.

[0037] Through the above technical solution, firstly, under conditions of large air flow, the driving component 21 of this utility model can drive the insertion plate 22 through the through hole 1 to insert it into the ground, thereby enabling the entire geographic information system data acquisition device 100 to be reliably fixed on the ground, avoiding shaking or displacement due to air flow, and effectively ensuring the accuracy of measurement and the reliability of the acquired data.

[0038] Secondly, since the insertion plate 22 of this utility model has a ring structure, compared with the fixing structure of the insertion rod in the existing related technologies, this utility model can be well adapted to soft sandy land (e.g., desertified land or desert). The ring structure of the insertion plate 22 can fix the geographic information system data acquisition device 100 in the horizontal direction from all angles of left, right and front and back, improving the measurement stability in soft sandy land.

[0039] Furthermore, it is understood that the overall structure of this utility model is simple, with the driving component 21 directly driving the insertion plate 22 without introducing a transmission structure (e.g., gears, racks, chains, etc.), which can be well adapted to the environment of soft sandy ground where there is easy interference from fine sand particles, and can ensure the reliable operation of the fixing component 2.

[0040] Example 2

[0041] This implementation method is based on Example 1, such as... Figures 2 to 4 As shown, the insertion plate 22 of this utility model may include four L-shaped first plates 221 and four connecting plates 222. The four L-shaped plates are connected end to end through the four connecting plates 222 to form a ring structure. The through hole 1 includes four L-shaped first through holes 11, which extend vertically. The four first through holes 11 are respectively provided in correspondence with the four first plates 221.

[0042] Thus, in this embodiment, the through hole 1 is configured as follows (see reference). Figure 2This can reduce the structural impact of the through hole 1 on the base plate 101, ensuring reliable support of the base plate 101 for the main body 102 of the data acquisition instrument, the drive component 21 and other structures. At the same time, the insertion plate 22, which is set in this way, can fix the geographic information system data acquisition device 100 in the horizontal direction from all angles of left, right and front and back, effectively ensuring the measurement stability in soft sand.

[0043] Furthermore, the four first plates 221 arranged in this way are connected by connecting plates 222, which can improve the overall structural strength of the insertion plate 22, thereby ensuring that the insertion plate 22 stably and reliably restricts the position of the geographic information system data acquisition device 100.

[0044] In a further improvement of embodiment 2, such as Figure 4 As shown, the insertion plate 22 of this utility model may further include two force transmission plates 223, which are respectively connected to two oppositely arranged connecting plates 222; two driving members 21 are provided, which are respectively connected to the two force transmission plates 223 in a one-to-one correspondence, so as to drive the insertion plate 22 to move in the vertical direction.

[0045] In this way, the force transmission plate 223 and the driving component 21 are configured to effectively ensure that the insertion plate 22 can be inserted into the ground smoothly as a whole, ensuring the uniformity of the insertion depth, and further improving the positional stability of the geographic information system data acquisition device 100 fixed in the soft sand.

[0046] In a further improvement of Embodiment 2, in the direction of the line connecting the two oppositely arranged first plates 221, the ratio of the projected length L1 of the connecting plate 222 to the projected length L2 of the insert plate 22 satisfies: 1 / 10≤L1 / L2≤1 / 2.

[0047] In this invention, if the length of the connecting plate 222 is longer than the length of the insert plate 22, the corresponding first plate 221 will be shorter, resulting in a poorer fixing effect of the insert plate 22. If the length of the connecting plate 222 is shorter than the length of the insert plate 22, the corresponding through hole 1 will be larger, resulting in a stronger weakening of the structural strength of the base plate 101 by the through hole 1, leading to poor structural strength of the base plate 101 and difficulty in stably and reliably supporting the data acquisition instrument body 102, the driving component 21, and other structures.

[0048] Therefore, in this utility model, the ratio of the projected length L1 of the connecting plate 222 to the projected length L2 of the insert plate 22 is limited so that the relative length of the connecting plate 222 is neither too large nor too small. This ensures that the fixing effect of the insert plate 22 is guaranteed, while also effectively guaranteeing the structural strength of the base plate 101.

[0049] Example 3

[0050] This implementation method is based on Example 1, such as... Figures 5 to 7 As shown, the through hole 1 of this utility model may include two symmetrically arranged second through holes 12. The second through holes 12 have a U-shaped structure and are inclined. The distance between the bottom of the second through hole 12 and the central axis of the base plate 101 is less than the distance between the top of the second through hole 12 and the central axis of the base plate 101. The insertion plate 22 includes two second plate bodies 224 that are adapted to the second through holes 12.

[0051] In this way, the two second plates 224 can be inserted into the soil at an inclined angle, allowing the insertion plate 22 to be inserted more smoothly. At the same time, the two second plates 224 can also fix the geographic information system data acquisition device 100 in the horizontal direction from all angles, effectively ensuring the measurement stability in soft sandy soil.

[0052] In one embodiment of this utility model, such as Figure 7 As shown, the present invention has two driving components 21, which are respectively connected to two second plates 224 to drive the two second plates 224 to move along the inclined direction of the second through hole 12.

[0053] The drive unit 21 is configured in this way so that the two drive units 21 can move independently, thereby enabling the geographic information system data acquisition device 100 to be used in relatively complex geographical conditions. For example, when there are some rocks or vegetation at the location where the geographic information system data acquisition device 100 is stationary, which prevents one of the second plates 224 from being inserted into the soil, the other second plate 224 can be activated independently to insert it into the soil, thus ensuring the positional stability of the geographic information system data acquisition device 100.

[0054] Example 4

[0055] This implementation method is based on Example 2, such as... Figure 3 As shown, in the vertical direction, the projection of the data acquisition instrument body 102 falls within the projection of the insertion plate 22, and the projection of the insertion plate 22 falls within the projection of the base plate 101.

[0056] In this way, the insertion plate 22 is configured in such a way that there is no spatial interference between the data acquisition unit body 102 and the moving insertion plate 22, ensuring that both can operate reliably. At the same time, the base plate 101 configured in this way provides sufficient installation space for the moving wheel 103, ensuring that the moving wheel 103 and its related structures (e.g., cables, shafts, drive devices, etc.) do not interfere with each other spatially, ensuring that both can operate reliably.

[0057] Example 5

[0058] Based on embodiment 2 or 3, in this embodiment, the thickness H1 of the base plate 101 and the height H2 of the insertion plate 22 in the vertical direction satisfy: 3cm≤H2-H1≤10cm.

[0059] When the insertion plate 22 is not inserted into the soil, it can be partially located in the through hole 1 of the base plate 101. However, when it is inserted into the soil, its insertion depth should not be too deep or too shallow. If it is too deep, it means that the insertion plate 22 is too long. A long insertion plate 22 will make the entire geographic information system data acquisition device 100 too tall, which is not conducive to the portability of the device. If it is too shallow, it will be difficult for the insertion plate 22 to reliably limit the geographic information system data acquisition device 100.

[0060] In view of this, in this embodiment, the thickness of the insertion plate 22 relative to the base plate 101 is limited to ensure that the insertion depth of the insertion plate 22 is within the range of 3cm to 10cm. This ensures that the insertion plate 22 can reliably limit the geographic information system data acquisition device 100, and also facilitates the lightweighting of the geographic information system data acquisition device 100.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
