Description

Technical Field

[0001] The present invention relates to the technical field of levels, and particularly to a leveling measurement device for environmental geological engineering observation. Background Technique

[0002] In environmental geological engineering, a level is used to determine the elevation of the geology, ensure the horizontality and verticality of the geology, and perform elevation control during stages such as foundation excavation and structure erection. The level calibrates the line of sight of the instrument (i.e., the aiming line of the telescope) to be in a horizontal state through its level vial. The bubble in the level vial is centered when the line of sight is horizontal, and at this time, the line of sight aimed by the telescope is the horizontal line of sight. The operator aims the telescope at a distant target point (usually a mark on the leveling staff), and adjusts the focal length of the telescope so that the image of the target point is clearly presented on the crosshair reticle. When the line of sight of the level is horizontal and the telescope is aimed at the target point, the operator reads the scale value at the intersection of the crosshairs on the leveling staff. This scale value is the elevation difference between the target point and the position where the level is located. By repeating the above steps at different positions, measuring the elevation differences between multiple points, and combining the known elevation of the reference point, the absolute elevations of other points can be calculated.

[0003] Before using the existing leveling measurement device for environmental geological engineering observation, it is necessary to use a bubble level to ensure the horizontality of the line of sight of the level by adjusting the foot screws of the level. After use, the foot screws need to be rotated back to their original positions for the next use. However, it is easy for the staff to forget to reset the foot screws after using the level and directly remove the level from the bracket and put it in the box for storage, which affects the next use of the level and the accuracy of the horizontal and vertical positions of the level for the next use.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-6 , the present invention provides a leveling measurement device for environmental geological engineering observation, including:

[0031] A leveling instrument base 1, the top of the leveling instrument base 1 is connected with an adjusting column 3 by a foot screw 2, the top of the adjusting column 3 is connected with a leveling instrument body 4, and a support base 5 is provided at the bottom of the leveling instrument base 1;

[0032] Reset reminder component 6 is arranged on the top of the level base 1. The reset reminder component 6 is composed of a first gear 601, a second gear 602, a fixing hole 603, a threaded rod 604, an auxiliary rod 605, and a moving hole 606. The outer side of the bottom of the foot screw 2 is fixedly sleeved with the first gear 601. A moving hole 606 is opened on the top of the level base 1. A second gear 602 located above the moving hole 606 is rotatably connected to the top of the level base 1. The external teeth of the first gear 601 are meshed with the second gear 602. The inner cavity of the second gear 602 is movably sleeved with a threaded rod 604 located in the inner cavity of the moving hole 606. The inner cavity of the top of the threaded rod 604 is movably sleeved with the auxiliary rod 605. The top of the auxiliary rod 605 is connected to the bottom of the level body 4. A fixing hole 603 is opened on the top of the support base 5. By providing the reset reminder component 6 on the top of the level base 1, when the level base 1 is in use and the position of the level body 4 is adjusted by rotating the foot screw 2, the foot screw 2 drives the first gear 601 to rotate. Since the first gear 601 is meshed with the second gear 602 and the second gear 602 is threadedly connected to the threaded rod 604, the moving hole 606 is driven to rotate and move downward, so that the lower part of the moving hole 606 enters the inner cavity of the fixing hole 603 and is connected thereto, enabling the connection between the level base 1 and the support base 5. On the basis of the original bolt fixation between the level base 1 and the support base 5, the threaded rod 604 is further used for connection, improving the connection stability between the level base 1 and the support base 5. At the same time, when the foot screw 2 is not reset, the level base 1 and the support base 5 cannot be separated and stored, so as to remind the staff to reset the foot screw 2 on the level base 1.

[0033] In an embodiment of the present invention, three reset reminder components 6 are provided on the top of the level base 1, and the three reset reminder components 6 are evenly distributed along the circumferential direction of the level base 1 near the center of the level base 1. By providing three on the top of the level base 1, it is convenient to correspond to the three foot screws 2, so that as long as any one of the three foot screws 2 is not reset, the level base 1 and the support base 5 cannot be separated, and only when all three foot screws 2 are reset can the level base 1 and the support base 5 be disassembled.

[0034] In an embodiment of the present invention, the bottom of the threaded rod 604 is flush with the bottom of the level base 1 in the initial state of the foot screw 2. By making the bottom of the threaded rod 604 flush with the bottom of the level base 1 in the initial state of the foot screw 2, it is ensured that only when the foot screw 2 is used can the threaded rod 604 be inserted into the fixing hole 603, so as to remind the staff that the foot screw 2 needs to be reset after use.

[0035] In an embodiment of the present invention, the fixing hole 603 is located directly below the moving hole 606, and the inner cavity of the second gear 602 is provided with a thread that meshes with the outer thread of the threaded rod 604.

[0036] In an embodiment of the present invention, a heat insulation and sunshade assembly 7 is provided on the top of the level body 4. The heat insulation and sunshade assembly 7 includes a support frame 701, a connecting shaft 702, a return spring 703, a first protective cover 704, a second protective cover 705, a fixing plate 706, and a pressing disc 707. Support frames 701 are fixedly installed on the front sides of the top of the level base 1. The upper parts of the two support frames 701 are respectively connected with connecting shafts 702 by return springs 703. The outer sides of the two connecting shafts 702 are respectively fixedly sleeved with a first protective cover 704 and a second protective cover 705. Fixing plates 706 are installed at the bottoms of the first protective cover 704 and the second protective cover 705. The lower part of the adjusting column 3 is fixedly installed with a pressing disc 707 located above the foot screw 2. The overall shapes of the first protective cover 704 and the second protective cover 705 are arc-shaped, and both the first protective cover 704 and the second protective cover 705 are made of heat insulation materials. By providing the heat insulation and sunshade assembly 7 on the top of the level base 1, when the level base 1 is in use, the first protective cover 704 and the second protective cover 705 are opened, so that the first protective cover 704 and the second protective cover 705 cover the top of the level body 4, which is convenient for shielding the sun from the level body 4 and avoiding the level body 4 from getting hot due to direct sunlight, thus affecting the service life of the level body 4.

[0037] In an embodiment of the present invention, when the bottom of the pressing disc 707 contacts the top of the fixing plate 706, the return spring 703 is in a twisted state, and the first protective cover 704 and the second protective cover 705 cover the outside of the level body 4. By having the return spring 703 in a twisted state when the bottom of the pressing disc 707 contacts the top of the fixing plate 706, and the first protective cover 704 and the second protective cover 705 covering the outside of the level body 4, it is convenient to protect the level body 4 when it is not in use.

[0038] In an embodiment of the present invention, a waterproof layer is provided on the connection part between the first protective cover 704 and the second protective cover 705 and on the outer surfaces of the first protective cover 704 and the second protective cover 705.

[0039] In an embodiment of the present invention, an eyepiece protection assembly 8 is provided on the front side of the second protective cover 705. A connecting rod 801 is fixedly installed on the front side of the second protective cover 705. The front end of the connecting rod 801 is fixedly installed with a connecting plate 802, and a protective cover 803 is fixedly installed at the bottom of the connecting plate 802. By providing the eyepiece protection assembly 8 on the front side of the first protective cover 704, when the level instrument body 4 is not needed, the protective cover 803 is used to cover the eyepiece on the level instrument body 4 to protect the eyepiece and prevent it from being damaged due to external collisions.

[0040] In an embodiment of the present invention, when the second protective cover 705 is in a closed state, the protective cover 803 is located in front of the eyepiece on the level instrument body 4, and a sponge layer is provided on the contact surface between the protective cover 803 and the eyepiece. By using the sponge layer on the protective cover 803 to contact the eyepiece, the friction between the protective cover 803 and the eyepiece during rotation is reduced, avoiding wear of the eyepiece.

[0041] Working principle: When using this device, the level instrument base 1 is fixed on the top of the support base 5 by external bolts. The level instrument body 4 is calibrated by the foot screws 2. When rotating the foot screws 2 to drive the adjusting column 3 to move upward, thereby adjusting the position of the level instrument body 4, the foot screws 2 drive the first gear 601 to rotate. Since the first gear 601 is meshed with the second gear 602, the second gear 602 is driven to rotate on the top of the level instrument base 1. Since the inner cavity of the second gear 602 is provided with a threaded rod 604, through the threaded connection between the second gear 602 and the threaded rod 604, the movable hole 606 is driven to rotate downward and move, so that the lower part of the movable hole 606 enters the inner cavity of the fixed hole 603 and is connected thereto, connecting the level instrument base 1 and the support base 5. On the basis of the original bolt fixation between the level instrument base 1 and the support base 5, the threaded rod 604 is further used to connect with the support base 5, improving the connection stability between the level instrument base 1 and the support base 5;

[0042] At this time, since the adjusting column 3 moves upward, the bottom of the adjusting column 3 is separated from the top of the fixed plate 706, releasing the restriction on the first protective cover 704 and the second protective cover 705, so that the second protective cover 705 and the first protective cover 704 can be opened upward by the return spring 703, opening the first protective cover 704 and the second protective cover 705 on the top of the level instrument body 4. Using the material of the first protective cover 704 and the second protective cover 705 and the waterproof layer on the surface, heat insulation and rain protection can be provided for the level instrument body 4;

[0043] While the second protective cover 705 rotates upward, it drives the protective cover 803 to rotate, separating the protective cover 803 from the level instrument body 4 and exposing the eyepiece on the level instrument body 4 for easy use;

[0044] After the use of the level body 4 is completed, unscrew the bolt connecting the level base 1 and the support base 5. Without resetting the foot screw 2, the level base 1 and the support base 5 cannot be separated and stored, so as to remind the staff to reset the foot screw 2 on the level base 1; by rotating the foot screw 2 in the reverse direction, using the first gear 601, the second gear 602 and the threaded rod 604, drive the threaded rod 604 to move upward, so that the threaded rod 604 is separated from the fixing hole 603, ensuring the reset of the foot screw 2 and facilitating the next use.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
