Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, specifically a geological surveying instrument applicable to different terrains. Background Technology

[0002] A geological surveying and mapping instrument is a professional instrument used in the geological field that integrates multiple technologies to measure and map geological information.

[0003] A Chinese patent with publication number CN118129723A discloses a surveying instrument for land surveying, comprising: a movable cylinder, which is sleeved on the side wall of a lens, and a transparent plate is fixedly connected to the other end of the movable cylinder; a rotating ring is rotatably connected to the side wall of the movable cylinder, and multiple arrayed levers are fixedly connected to the side wall of the rotating ring; before surveying, it is convenient to adjust the light intensity to a suitable range, and at the same time, it can detect the refraction of air to ensure the accuracy of the surveying results; it can also automatically blow air to clean the surface of the transparent plate, and ensure the accuracy of the surveying results.

[0004] However, the above-mentioned surveying instrument still has some problems. In practical applications, when conducting surveying operations in some complex terrains, the surveying instrument may not be able to maintain a horizontal position, which will reduce the accuracy of the surveying data. Therefore, in order to address the above problems, a geological surveying instrument applicable to different terrains is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a geological surveying instrument that can be applied to different terrains.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a geological surveying instrument applicable to different terrains, including a mounting plate. Three mounting seats are equidistantly mounted on the outer side of the mounting plate. A support rod is mounted inside each mounting seat via a pin. A rectangular groove is formed inside the support rod, and an adjusting rod is slidably mounted inside the rectangular groove. A rack is mounted on one side of the adjusting rod. A mounting frame is mounted on one side of the bottom of the support rod. A rotating shaft is rotatably mounted inside the mounting frame. A gear is mounted on the outer side of the rotating shaft. A handle is mounted on one side of the rotating shaft, and a locking screw is rotatably mounted inside the handle. A through groove is formed between the support rod and the mounting frame, and the gear meshes with the rack through the through groove. A groove is formed at the bottom of the adjusting rod, and a pad is mounted inside the groove via a pin. This allows for individual adjustment of the position of the adjusting rod within the rectangular groove to adapt to different terrains, ensuring that the surveying instrument remains level on various terrains and improving data accuracy.

[0007] Preferably, a fixing rod is installed on one side of the mounting plate, a gravity rope is installed on the bottom side of the fixing rod, and a scale is installed on the outer wall of the mounting plate on the side of the gravity rope, which can intuitively display whether the mounting plate is tilted, thereby assisting in adjusting the surveying instrument to a horizontal state.

[0008] Preferably, a cylinder is mounted on the bottom side of the mounting plate, and a threaded rod is rotatably mounted between the two sides of the cylinder. A rotating handle is mounted on the bottom side of the threaded rod. Three sliding grooves are equally spaced inside the cylinder, and a mounting ring is slidably mounted inside the sliding grooves. A threaded hole is opened at the middle end of the mounting ring, and the threaded rod passes through the threaded hole. U-shaped seats are mounted on the outer side of the mounting ring and one side of the support rod. Three U-shaped seats are mounted on the mounting ring. A connecting rod is installed between the support rod and the U-shaped seats on the mounting ring to realize the adjustment of the height of the surveying instrument.

[0009] Preferably, a rotating shaft is mounted on the top side of the mounting plate, a support plate is mounted on the top side of the rotating shaft, and the surveying instrument body is mounted on the top side of the support plate, so that the surveying instrument can rotate around the rotating shaft for angle adjustment.

[0010] Preferably, the top side of the mounting plate is equidistantly engraved with several scale lines, a grooved wheel is installed on the outer side of the rotating shaft, and a guide rod pointing to the scale lines is installed on the bottom side of the grooved wheel, which helps to accurately adjust the rotation angle of the surveying instrument.

[0011] Preferably, a slide rod is slidably installed through the top of the mounting plate, a limit block is installed on the bottom side of the slide rod, a connecting block is installed on the top side of the slide rod, two locking blocks that engage with the slotted wheel are installed on the outer side of the connecting block, and a return spring is installed between the connecting block and the mounting plate. The return spring is sleeved on the outer side of the slide rod. After the angle adjustment is completed, the slotted wheel is locked by the locking blocks to keep the surveying instrument in the current position and prevent accidental movement.

[0012] The advantages of this utility model are:

[0013] 1. This utility model involves rotating a handle, which drives a rotating shaft and gear to rotate. The rotation of the gear causes the adjusting rod to slide up and down within a rectangular groove, extending the adjusting rod at that angle until the mounting plate is observed to be nearly horizontal through the gravity rope and the scale, thus achieving fine-tuning. This ensures that the surveying instrument remains horizontal in different terrains, improving data accuracy. After adjustment, the handle is fixed by rotating the locking screw to prevent the position of the adjusting rod from changing due to external factors during the surveying process.

[0014] 2. When the connecting block is pressed down, it causes the sliding rod to move downward. At this time, the return spring is compressed, the locking block disengages from the slot wheel, and then the rotating shaft drives the support plate and the surveying instrument body to rotate. The operator can precisely control the rotation angle of the surveying instrument body according to the scale line indicated by the pointer rod. When the connecting block is released, the sliding rod moves upward under the action of the return spring, and the locking block re-engages into the slot wheel, preventing the surveying instrument body from rotating accidentally during the measurement process and ensuring the stability of the measurement angle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a geological surveying instrument applicable to different terrains includes a mounting plate 1. Three mounting seats 2 are equidistantly mounted on the outer side of the mounting plate 1. A support rod 3 is mounted inside the mounting seat 2 via a pin. A rectangular groove 4 is formed inside the support rod 3. An adjusting rod 5 is slidably mounted inside the rectangular groove 4. A rack 6 is mounted on one side of the adjusting rod 5. A mounting frame 7 is mounted on one side of the bottom end of the support rod 3. A rotating shaft 8 is rotatably mounted through the mounting frame 7. A gear 9 is mounted on the outer side of the rotating shaft 8. A handle 10 is mounted on one side of the rotating shaft 8. A locking screw 11 is rotatably mounted inside the handle 10. A through groove 12 is formed between the support rod 3 and the mounting frame 7. The gear 9 passes through the through groove 12 and meshes with the rack 6. A groove 13 is formed at the bottom end of the adjusting rod 5. A pad 14 is mounted inside the groove 13 via a pin.

[0024] A fixing rod 15 is installed on one side of the mounting plate 1, a gravity rope 16 is installed on the bottom side of the fixing rod 15, and a scale 17 is installed on the outer wall of the mounting plate 1 on the side of the gravity rope 16.

[0025] A cylinder 18 is mounted on the bottom side of the mounting plate 1. A threaded rod 19 is rotatably mounted between the two sides of the cylinder 18. A rotating handle 20 is mounted on the bottom side of the threaded rod 19. Three sliding grooves 21 are equidistantly opened inside the cylinder 18. A mounting ring 22 is slidably mounted inside the sliding grooves 21. A threaded hole is opened at the middle end of the mounting ring 22. The threaded rod 19 passes through the threaded hole. U-shaped seats 23 are mounted on the outer side of the mounting ring 22 and one side of the support rod 3. Three U-shaped seats 23 are mounted on the mounting ring 22. A connecting rod 24 is installed between the support rod 3 and the U-shaped seats 23 on the mounting ring 22. In actual application, when conducting surveying work on some complex terrains, it will lead to... If the surveying instrument cannot maintain a horizontal position during surveying operations, the accuracy of the surveying instrument's detection data will be reduced. When the operator rotates the rotating handle 20, the threaded rod 19 will rotate, and the mounting ring 22 will move up or down along the slide groove 21. That is, if the surveying instrument needs to be raised, the mounting ring 22 will rise. The mounting ring 22 is connected to the U-shaped seat 23 on the support rod 3 through the connecting rod 24, so that the included angle between the support rod 3 and the mounting plate 1 is reduced, thereby raising the height of the mounting plate 1 and the surveying instrument body 27 mounted on it. Conversely, the height of the surveying instrument body 27 will decrease. The pad 14 will automatically rotate to a suitable angle according to the unevenness of the terrain, increasing the contact area with the ground and distributing the weight of the surveying instrument.

[0026] When adapting to different terrain height differences, first, observe the gravity rope 16 and scale 17 on one side of the mounting plate 1 to initially determine if the mounting plate 1 is level. If it is not level, and a certain corner of the mounting plate 1 is too low, the adjusting rod 5 at that position needs to be adjusted. The operator loosens the locking screw 11 and turns the handle 10. The handle 10 drives the rotating shaft 8 and gear 9 to rotate. Since gear 9 meshes with rack 6, the rotation of gear 9 will cause the adjusting rod 5 to slide up and down in the rectangular groove 4, so that the adjusting rod 5 at that corner is extended until the mounting plate 1 is observed to be close to level through the gravity rope 16 and scale 17, thus achieving fine adjustment and ensuring that the surveying instrument can remain level on different terrains, improving data accuracy. After adjustment, the locking screw 11 is rotated to fix the handle 10 to prevent the position of the adjusting rod 5 from changing due to external factors during the surveying process.

[0027] Please see Figure 1 , 2 As shown in Figures 3 and 5, a rotating shaft 25 is mounted on the top side of the mounting plate 1, a support plate 26 is mounted on the top side of the rotating shaft 25, and a surveying instrument body 27 is mounted on the top side of the support plate 26.

[0028] The top side of the mounting plate 1 is equidistantly engraved with several scale lines 28, the outer side of the rotating shaft 25 is equipped with a slotted wheel 30, and the bottom side of the slotted wheel 30 is equipped with a pointing rod 29 pointing to the scale lines 28.

[0029] A sliding rod 31 is slidably mounted through the top of the mounting plate 1. A limit block 32 is mounted on the bottom side of the sliding rod 31, and a connecting block 33 is mounted on the top side of the sliding rod 31. Two locking blocks 34 that engage with the locking wheel 30 are mounted on the outer side of the connecting block 33. A return spring 35 is installed between the connecting block 33 and the mounting plate 1, and the return spring 35 is sleeved on the outer side of the sliding rod 31. During operation, the geological surveying and mapping instrument is a professional instrument used in the geological field, integrating multiple technologies to measure and map geological information. When it is necessary to adjust the measuring angle of the instrument body 27, the operator presses down on the connecting block 3. 3. Connecting block 33 drives slide rod 31 to move downward. At this time, return spring 35 is compressed, and locking block 34 disengages from slot wheel 30. Then, the operator rotates shaft 25, which drives support plate 26 and surveying instrument body 27 to rotate. The operator precisely controls the rotation angle of surveying instrument body 27 according to the scale line 28 indicated by pointer rod 29. After the angle adjustment is completed, connecting block 33 is released. Under the action of return spring 35, slide rod 31 moves upward, and locking block 34 re-engages into slot wheel 30, locking the position of shaft 25 to prevent surveying instrument body 27 from rotating accidentally during measurement and to ensure the stability of the measurement angle.

[0030] Working principle: Rotating the rotating handle 20 drives the threaded rod 19 to rotate, and the mounting ring 22 will move up or down along the slide groove 21. That is, when the surveying instrument needs to be raised, the mounting ring 22 will rise. The mounting ring 22 is connected to the U-shaped seat 23 on the support rod 3 through the connecting rod 24, so that the included angle between the support rod 3 and the mounting plate 1 is reduced, thereby raising the height of the mounting plate 1 and the surveying instrument body 27 mounted on it. Conversely, the height of the surveying instrument body 27 decreases. The pad 14 will automatically rotate to a suitable angle according to the unevenness of the terrain, increasing the contact area with the ground and distributing the weight of the surveying instrument.

[0031] When adapting to different terrain height differences, first, observe the gravity rope 16 and scale 17 on one side of the mounting plate 1 to initially determine whether the mounting plate 1 is level. If it is not level, and a certain corner of the mounting plate 1 is too low, the adjusting rod 5 at that position needs to be adjusted. The operator loosens the locking screw 11 and turns the handle 10. The handle 10 drives the rotating shaft 8 and gear 9 to rotate. Since the gear 9 meshes with the rack 6, the rotation of the gear 9 will cause the adjusting rod 5 to slide up and down in the rectangular groove 4, so that the adjusting rod 5 at that corner is extended until the mounting plate 1 is observed to be close to level through the gravity rope 16 and scale 17, thus achieving fine adjustment and ensuring that the surveying instrument can remain level on different terrains, improving data accuracy. After the adjustment is completed, the locking screw 11 is rotated to fix the handle 10 to prevent the position of the adjusting rod 5 from changing due to external factors during the surveying process.

[0032] When it is necessary to adjust the measuring angle of the surveying instrument body 27, the operator presses down the connecting block 33. The connecting block 33 drives the slide rod 31 to move downward. At this time, the return spring 35 is compressed, and the locking block 34 disengages from the slot wheel 30. Then, the operator rotates the rotating shaft 25, which drives the support plate 26 and the surveying instrument body 27 to rotate. The operator precisely controls the rotation angle of the surveying instrument body 27 according to the scale line 28 indicated by the pointer rod 29. After the angle adjustment is completed, the connecting block 33 is released. Under the action of the return spring 35, the slide rod 31 moves upward, and the locking block 34 re-engages into the slot wheel 30, locking the position of the rotating shaft 25 to prevent the surveying instrument body 27 from rotating accidentally during the measurement process and to ensure the stability of the measuring angle.
