Description

Technical Field

[0001] This utility model relates to the field of geological surveying and mapping technology, and in particular to an adjustable surveying instrument for complex terrain. Background Technology

[0002] Geological mapping is an important field combining geology and surveying, and it is of great significance to resource exploration and engineering construction. It includes measuring and mapping the topographic relief, mountain and river orientation, and slope and aspect of the Earth's surface. Through field measurement, aerial photogrammetry, or satellite remote sensing, topographic data is acquired to draw contour maps and digital elevation models, providing basic topographic information for geological research. For example, when conducting geological mapping in mountainous areas, accurate topographic mapping helps to analyze the relationship between mountain structure, water system distribution, and geological structure, which requires the use of mapping instruments.

[0003] Surveying instruments are crucial equipment in geological surveying and many other surveying fields. Different types of surveying instruments have their own characteristics in terms of function, principle, and application scenarios. Under adverse weather conditions such as strong light, dense fog, or sandstorms, the optical structure and photoelectric ranging function of existing surveying instruments can be interfered with, affecting the accuracy and stability of measurement data. For example, in geological surveying in desert areas, sandstorms can severely affect the observation effect of total stations. Current solutions include equipping them with signal enhancers or anti-reflective shields. Signal enhancers can amplify reflected signals and improve the accuracy of long-distance measurements, while anti-reflective shields can reduce interference from strong light and ensure normal observation under complex lighting conditions. However, in mountainous areas with strong winds, even after initial fixation, the tripod may sway due to external factors. For example, at construction sites near highways, ground vibrations caused by passing vehicles can cause slight displacement and swaying of the surveying instrument, thus interfering with the measurement process and reducing measurement accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable surveying instrument for complex terrain, aiming to improve the problem in the prior art where tripod swaying is caused by external factors, such as ground vibration caused by passing vehicles at construction sites near highways, which causes slight displacement and swaying of the surveying instrument, thereby interfering with the measurement process and reducing measurement accuracy.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable surveying instrument for complex terrain, comprising a triangular shell, a surveying device rotatably mounted on the top of the triangular shell, a hydraulic rod fixedly connected to the inner top wall of the triangular shell, a connecting shell fixedly connected to the bottom end of the hydraulic rod, electric push rods rotatably connected to the left and right sides of the bottom wall of the connecting shell, an arc-shaped plate rotatably connected to the bottom end of the electric push rod, the top of the arc-shaped plate rotatably connected to the middle of the bottom wall of the connecting shell via a rotating column, vertical cones fixedly connected to the front and rear sides of the bottom wall of the arc-shaped plate, two fixed columns fixedly connected to adjacent sides of the two arc-shaped plates, and multiple retraction mechanisms provided on the outer wall of the triangular shell, the retraction mechanisms being used to improve the space utilization rate of the device.

[0006] As a further description of the above technical solution:

[0007] The shrinking mechanism includes multiple rotating shafts, the tops of which are rotatably connected to the outer wall of the triangular shell. The bottom of each rotating shaft is rotatably connected to an adjusting shell. An adjusting rod is slidably connected inside the adjusting shell. A locking plate is rotatably connected to the front side of the adjusting rod. Multiple locking slots are provided on one side of the adjusting shell. One side of the locking plate engages with the locking slots. A cleaning shell is fixedly connected to the bottom of the outer wall of the adjusting shell. Bolts are threaded to both the left and right sides of the cleaning shell. A cleaning scraper is threaded to the end of each bolt.

[0008] As a further description of the above technical solution:

[0009] The retraction mechanism also includes multiple support plates, which are respectively fixedly connected to the bottom of the corresponding adjustment rod.

[0010] As a further description of the above technical solution:

[0011] Each of the bolts has a rubber ring fixedly connected to its center, and the rubber rings are all cylindrical in shape.

[0012] As a further description of the above technical solution:

[0013] A control switch is fixedly connected to the front of the surveying equipment, and the control switch is electrically connected to the surveying equipment, the hydraulic rod, and the electric push rod.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the height of the arc-shaped plate can be adjusted by raising and lowering the connecting shell, thereby adapting to the surveying needs at different heights. At the same time, driven by the bottom of the electric push rod, the arc-shaped plate can rotate around the rotating column after penetrating the soil. Thus, the soil is compacted under the action of the arc-shaped plate and the fixed column, thereby improving the stability of the surveying instrument and avoiding the situation where the measurement accuracy is reduced due to interference in the measurement process.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an adjustable surveying instrument for complex terrain, comprising a triangular shell 1. A surveying device 3 is rotatably mounted on the top of the triangular shell 1, enabling the surveying device 3 to map complex terrain when activated. A hydraulic rod 4 is fixedly connected to the inner top wall of the triangular shell 1, and a connecting shell 5 is fixedly connected to the bottom end of the hydraulic rod 4. Activation of the hydraulic rod 4 drives the connecting shell 5 to move, thereby adjusting the height of the surveying device 3. Electric push rods 6 are rotatably connected to the left and right sides of the bottom wall of the connecting shell 5. The bottom end of the push rod 6 is rotatably connected to an arc plate 7. The top of the arc plate 7 is rotatably connected to the middle of the bottom wall of the connecting shell 5 through a rotating column 8. Driven by the bottom end of the electric push rod 6, the arc plate 7 can rotate around the rotating column 8. The front and rear sides of the bottom wall of the arc plate 7 are fixedly connected to vertical cones 9. Two fixed columns 10 are fixedly connected to adjacent sides of the two arc plates 7. With the cooperation of multiple fixed columns 10, the soil can be compacted in the soil. The outer wall of the triangular shell 1 is provided with multiple shrinkage mechanisms 2. The shrinkage mechanisms 2 are used to improve the space utilization of the device.

[0032] Specifically, by activating the hydraulic rod 4, its bottom end drives the connecting shell 5 to rise and fall, adapting to various surveying needs. By activating the electric push rod 6, its bottom end drives the arc plate 7 to move. However, under the constraint of the rotating column 8, the displacement of the arc plate 7 is somewhat constrained, allowing the arc plate 7 to rotate around the rotating column 8 after penetrating the soil. This enables the arc plate 7 to open or close, thus working in conjunction with the fixed column 10 to achieve the effect of compacting the soil. This enhances the fixing effect of the device and improves the stability of the surveying instrument, helping to avoid external interference during the measurement process, thereby ensuring the accuracy of the measurement and avoiding measurement data errors caused by unstable factors.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The retraction mechanism 2 includes multiple rotating shafts 201, the tops of which are rotatably connected to the outer wall of the triangular shell 1. An adjusting shell 202 is rotatably connected to the bottom of each rotating shaft 201. An adjusting rod 203 is slidably connected inside the adjusting shell 202. The sliding of the adjusting rod 203 allows for selection of its length according to usage requirements. A locking plate 204 is rotatably connected to the front of the adjusting rod 203. Multiple locking slots 205 are provided on one side of the adjusting shell 202. One side of the locking plate 204 is connected to one of the locking slots 205. 5. The locking plate 204 and the locking groove 205 engage to lock the length of the adjusting rod 203. The bottom of the outer wall of the adjusting shell 202 is fixedly connected to the cleaning shell 206. Bolts 207 are threaded on both sides of the cleaning shell 206. The cleaning scraper 208 can be disassembled and assembled through the bolts 207, which improves the flexibility of the cleaning scraper 208. The end of the bolt 207 is threaded to the cleaning scraper 208. Then, the extension and retraction adjusting rod 203 can be cleaned through the cleaning scraper 208.

[0034] Specifically, by rotating the locking plate 204, the locking plate 204 and the locking groove 205 are unlocked, allowing the adjusting rod 203 to slide freely inside the adjusting shell 202. This allows the device to flexibly adjust its lateral stability according to different usage needs, thus adapting to various complex terrain environments. During the extension and retraction of the adjusting rod 203, dust and dirt adhering to its outer wall are removed by the cleaning scraper 208. This cleaning scraper 208 is fixed in place by bolts 207, effectively preventing dust and dirt from accumulating on the inner wall of the adjusting shell 202, thereby avoiding potential corrosion problems. When carrying or storing the device, the overall volume of the device is reduced by retracting the adjusting rod 203 to its minimum length. This not only makes it easy to carry but also improves the space utilization of the device, making it more portable and efficient.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The shrinking mechanism 2 also includes multiple support plates 209, which are fixedly connected to the bottom of the corresponding adjusting rods 203; rubber rings 210 are fixedly connected to the middle of multiple bolts 207, and the shape of the multiple rubber rings 210 is cylindrical; a control switch 12 is fixedly connected to the front side of the surveying equipment 3, and the control switch 12 is electrically connected to the surveying equipment 3, the hydraulic rod 4 and the electric push rod 6 respectively;

[0036] Specifically, the connection of the support plate 209 improves the auxiliary support effect, the rubber ring 210 reduces the rotational damage of the bolt 207 to the cleaning shell 206, and the control switch 12, which is electrically connected to the surveying equipment 3, the hydraulic rod 4 and the electric push rod 6 respectively, enables the control switch 12 to open and close the equipment.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A handle 13 is fixedly connected to the top wall of the surveying equipment 3, and a rubber sleeve 14 is fixedly connected to the middle of the handle 13; multiple arc grooves 11 are opened at the bottom of the two arc plates 7, and the multiple arc grooves 11 are opened at equal intervals; a protective shell 15 is fixedly connected to the top of the inner wall of the surveying equipment 3, and inclined surfaces are provided on the front and rear sides of the protective shell 15.

[0038] Specifically, the rubber sleeve 14 improves the anti-slip effect of the handle 13 when using it, the opening of multiple arc grooves 11 improves the toughness of the arc plate 7, and the connection of the protective shell 15 improves the protection of the lens of the surveying equipment 3.

[0039] Working principle: When in use, the hydraulic rod 4 is activated, which drives the connecting shell 5 to rise and fall, allowing the height of the surveying equipment 3 to be adjusted to meet different surveying needs. At the same time, the electric push rod 6 is activated, which drives the arc plate 7 to move at its bottom. However, under the displacement restriction of the rotating column 8, the arc plate 7 can rotate around the rotating column 8 after penetrating the soil through the vertical cone 9, thereby achieving the effect of opening or closing. This, together with the fixed column 10, achieves the purpose of compacting the soil to improve the fixation effect of the device, thereby improving the stability of the surveying instrument and avoiding the situation where the measurement process is interfered with and reduces the measurement accuracy.

[0040] Furthermore, by rotating the locking plate 204, the locking plate 204 is unlocked from the locking groove 205, allowing the adjusting rod 203 to slide within the adjusting housing 202. This enables the device to adjust its lateral stability according to usage requirements, adapting to various complex terrains. Simultaneously, during the extension and retraction of the adjusting rod 203, dust and dirt adhering to its outer wall can be scraped off by the cleaning scraper 208 installed via bolts 207, preventing dust and dirt from adhering to the inner wall of the adjusting housing 202 and causing corrosion. During transport, the adjusting rod 203 is retracted, reducing the device's size and improving its space utilization.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
