Description

Technical Field

[0001] The invention relates to the technical field of geological investigation and survey, and in particular to a field ecological geological investigation auxiliary device. Background Art

[0002] Ecological geological survey plays a vital role in environmental protection and sustainable development. It reveals the structure and function of the ecosystem by analyzing the relationship between geology and the ecosystem, and then helps us understand the impact of geological factors on the biological community and the feedback of the biological community on the geological environment. The role of ecological geological survey is mainly reflected in the following aspects: first, to evaluate the status of the ecosystem and find out the root causes of environmental problems; second, to provide a scientific basis for resource utilization and ecological restoration; third, to maintain ecological balance and promote sustainable development. Through ecological geological survey, we can better formulate ecological protection measures and achieve a win-win situation for economic development and environmental protection.

[0003] There are many types of auxiliary devices for field eco-geological surveys, such as: compass, a traditional and reliable direction-indicating tool, suitable for situations where there is no electronic signal or the occurrence of geological interfaces needs to be accurately measured; auxiliary drawing devices: such as GPS, drawing boards, pencils, rulers, etc. These devices or equipment can help with positioning and navigation, assist investigators in planning routes, and record data such as geological phenomena and ecological characteristics. The specific location and orientation within the survey area are determined using longitude and latitude positioning, thereby ensuring that the drawn graphics are consistent with the actual geological and ecological conditions.

[0004] In the traditional geological survey and mapping process, it is sometimes necessary to determine the area where a certain geological phenomenon or ecological feature is located. The staff needs to mark a large number of positioning points on a map or drawing board marked with longitude and latitude, and draw lines through the positioning points. In the process of marking the positioning points, the longitude and latitude of the positioning points on the map are first determined, and a point position is determined by two longitude and latitude lines. When determining the longitude and latitude of the lines, since calipers and pencils need to be used to align the scale lines for drawing, there may be some deviations in this process, resulting in the displacement of the drawn longitude and latitude lines, which makes the longitude and latitude of the positioning points have some errors, resulting in deviations between the actually drawn area and the actual geological and ecological area. Therefore, a field ecological geological survey auxiliary device is proposed. Summary of the invention

[0024] The two latitude adjustment screw rods 19 are fixedly connected to a transmission flywheel 28 at one end close to the latitude display compass 4. The two transmission flywheels 28 are connected to the first belt 7 and are used to drive the two latitude adjustment screw rods 19 to drive the threaded slider 17 to move.

[0025] The transmission rod 21 and the latitude adjustment screw rod 19 are fixedly connected to the dial main gear 22 at one end close to the dial driven gear 24.

At the same time, the drawing board 3 is provided with longitude and latitude scales for positioning. Each rotation of the pointer 26 corresponds to a range of longitude and latitude on the drawing board 3. By observing the number of scales in the latitude display compass 4 pointed by the pointer 26, the position of the positioning pin 12 on the drawing board 3 can be determined. Then, the side of the coordinate paper close to the positioning pin 12 is facing the surveying and mapping shell 2, and the shoulder strap mounting hole 9 is used to install the shoulder strap.

At this time, the latitude value of the positioning point is consistent with the latitude number of the sampling point in the actual target area.

[0028] Embodiment 2 like Figure 1 - Fig. 9 As shown, based on the first embodiment, a support block 18 is slidably provided on the inner side of the surveying and mapping housing 2, and the support block 18 is slidably connected to the transmission rod 21. A plurality of grooves 30 are provided on the outer side of the transmission rod 21. The transmission rod 21 extends to the outer side of the inner side of the support block 18 and is slidably provided with a first driving gear 31. The support block 18 is used to support the first driving gear 31, and the groove 30 is used for the sliding and rotation positioning of the first driving gear 31.

[0029] The threaded slider 17 and the fixed slider 13 are fixedly connected to the support block 18. The inner side of the fixed slider 13 is rotatably connected to the first driven gear 29. The first driven gear 29 is meshed with the first driving gear 31. The transmission rod 21 rotates and drives the first driving gear 31 to drive the first driven gear 29 to rotate.

[0030] The first driven gear 29 extends to the two ends of the outer side of the fixed slide 13 and is fixedly connected to the longitude driving gear 15. The end of the fixed slide 13 away from the first driven gear 29 is symmetrically rotatably connected to the longitude driven gear 11. The longitude driven gear 11 and the longitude driving gear 15 are jointly sleeved and connected with the longitude adjustment chain 16. The longitude adjustment chain 16 is fixedly connected to the positioning pin 12. The first driven gear 29 drives the longitude driving gear 15 to drive the longitude adjustment chain 16 to move in a circle.

[0031] A sliding groove 14 is symmetrically provided on one side of the fixed slide plate 13 close to the positioning pin 12 . The two sliding grooves 14 are slidably connected to the positioning pin 12 . The longitude adjustment chain 16 drives the positioning pin 12 to move along the sliding groove 14 by circular motion.

[0032] In this embodiment, after the above operation is completed, the groove 30 is used to clamp the first driving gear 31 by using the provided groove 30, so that the first driving gear 31 can slide on the outer side of the transmission rod 21, and the first driving gear 31 is driven to rotate by using the transmission rod 21. By rotating the longitude handle 6, the longitude handle 6 rotates to drive the transmission rod 21 to rotate, and the transmission rod 21 rotates to drive the first driving gear 31 to rotate by itself, and the first driven gear 29 rotates by itself to drive the rotation of the two longitude driving gears 15. The two longitude driving gears 15 respectively drive the longitude adjustment chain 16 to move in a circular motion, and the circular motion of the longitude adjustment chain 16 drives the positioning pin 12 to move along the guide of the slide groove 14. After the above process is completed, the positioning pin 12 is moved in two mutually perpendicular directions. The two perpendicular directions can represent the longitude and latitude of the coordinate paper. At the same time, the transmission rod 21 rotates to drive the dial main gear 22 to carry The movable dial chain 23 moves in a circle, and the dial chain 23 drives the dial driven gear 24 to rotate and drive the pointer 26 to display the pointer reading on the inner side of the longitude display compass 8. By observing whether the value of the longitude display compass 8 is consistent with the longitude value of the sampling point, the positioning needle 12 is used to punch and locate on the coordinate paper. At this time, the longitude value of the positioning point is consistent with the longitude value of the sampling point, so that the positioning of a positioning point is completed. Finally, the above operation is repeated to complete the positioning of a large number of positioning points, and then the limit bolt 10 is rotated to take the drawing board 3 out of the two symmetrically arranged drawing board slots 20. Then the staff uses a pencil to connect these points and draw a closed figure. This figure is the topographic map of the target area actually investigated. Since the top plate 1 and the drawing board 3 are both made of transparent acrylic plates, the staff can clearly see the movement of the positioning needle 12 and the punching and positioning of the positioning needle 12 on the coordinate paper each time.
