Description

Technical Field

[0001] The invention relates to the technical field of levels, in particular to a leveling device for environmental geological engineering observation. Background Art

[0002] In environmental geological engineering, the level is used to determine the elevation of the geology, ensure the horizontality and verticality of the geology, and perform elevation control in stages such as foundation excavation and structure construction. The level uses its level to calibrate the sight axis of the instrument (i.e. the sight line of the telescope) to be in a horizontal state. The bubble in the level is centered when the sight axis is horizontal, and the sight line of the telescope is the horizontal sight line. The operator aims the telescope at a distant target point (usually the mark on the level ruler) and adjusts the focus of the telescope so that the image of the target point is clearly presented on the crosshair scale. When the sight axis of the level is horizontal and the telescope is aimed at the target point, the operator reads the scale value on the level ruler where the crosshairs intersect. This scale value is the height difference of the target point relative to the location of the level. By repeating the above steps at different locations, the height difference between multiple points is measured, and combined with the known elevation of the reference point, the absolute elevation of other points can be calculated.

[0003] Before using the existing leveling measuring device for environmental geological engineering observation, a bubble level is required to adjust the foot screw of the level to center the bubble and ensure that the sighting axis of the level is horizontal. After use, the foot screw needs to be rotated back to reset it for the next use. However, the staff tends to forget to reset the foot screw after using the level and directly remove the level from the bracket and put it in a box for storage, which affects the next use of the level and the accuracy of the horizontal and vertical position of the level when it is used next time.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 6 The present invention provides a leveling device for environmental geological engineering observation, comprising: A level base 1, the top of the level base 1 is connected to an adjustment column 3 by a foot screw 2, the top of the adjustment column 3 is connected to a level body 4, and a bracket seat 5 is provided at the bottom of the level base 1; The reset reminder component 6 is arranged on the top of the level base 1. The reset reminder component 6 consists of a first gear 601, a second gear 602, a fixed hole 603, a threaded rod 604, an auxiliary rod 605, and a movable hole 606. The outer side of the bottom of the foot screw 2 is fixedly sleeved with the first gear 601, and the top of the level base 1 is provided with a movable hole 606. The top of the level base 1 is rotatably connected with the second gear 602 located above the movable hole 606. The outer teeth of the first gear 601 and the second gear 602 are meshed with each other. The inner cavity of the second gear 602 is movably sleeved with a threaded rod 604 located in the inner cavity of the movable hole 606. The inner cavity of the top of the threaded rod 604 is movably sleeved with an auxiliary rod 605. The top of the auxiliary rod 605 is connected to the bottom of the level body 4, and the top of the bracket seat 5 is provided with a fixing hole 603. A reset reminder component 6 is provided on the top of the level base 1. When the level base 1 is in use, when the foot screw 2 is rotated to adjust the position of the level body 4, the foot screw 2 drives the first gear 601 to rotate. Due to the meshing connection between the first gear 601 and the second gear 602, and the threaded connection between the second gear 602 and the threaded rod 604, the movable hole 606 is driven to rotate and move downward, so that the lower part of the movable hole 606 enters the inner cavity of the fixing hole 603 and is connected thereto, so that the level base 1 and the bracket seat 5 are connected. On the basis of the original bolt fixation between the level base 1 and the bracket seat 5, the threaded rod 604 is used to connect them, thereby improving the stability of the connection between the level base 1 and the bracket seat 5. At the same time, when the foot screw 2 is not reset, the level base 1 and the bracket seat 5 cannot be separated and stored, so as to remind the staff to reset the foot screw 2 on the level base 1.

[0023] In one embodiment of the present invention, three groups of reset reminder components 6 are provided on the top of the level base 1, and the three groups of reset reminder components 6 are evenly distributed along the circumference of the level base 1 near the center of the circle of the level base 1. By providing three groups on the top of the level base 1, it is convenient to correspond to the three foot screws 2, so that if any of the three foot screws 2 is not reset, the level base 1 and the bracket seat 5 cannot be separated. Only when the three foot screws 2 are reset, can the level base 1 and the bracket seat 5 be disassembled.

[0024] In one embodiment of the present invention, the bottom of the threaded rod 604 of the foot screw 2 is flush with the bottom of the level base 1 in the initial state. By making the bottom of the threaded rod 604 flush with the bottom of the level base 1 in the initial state, it is ensured that the threaded rod 604 can only be inserted into the fixing hole 603 by using the foot screw 2, so as to remind the staff to reset the foot screw 2 after using it.

The front side of the top of the level base 1 is fixedly installed with a support frame 701. The upper parts of the two support frames 701 are respectively connected to the connecting shafts 702 by the return springs 703. The outer sides of the two connecting shafts 702 are respectively fixedly sleeved with the first protective cover 704 and the second protective cover 705. The bottom of the first protective cover 704 and the bottom of the second protective cover 705 are both installed with a fixing plate 706. The lower part of the adjusting column 3 is fixedly installed with a pressing disc 707 located above the foot screw 2. The first protective cover 704 and the second protective cover 705 are arc-shaped as a whole, and the first protective cover 704 and the second protective cover 705 are both made of heat-insulating materials. A heat-insulating sunshade assembly 7 is provided 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, thereby shading the level body 4 from sunlight and preventing the level body 4 from heating up due to direct sunlight and affecting the life of the level body 4.

[0027] In one embodiment of the present invention, the return spring 703 is in a torsion 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 cover the outside of the level body 4. By pressing the return spring 703 in a torsion 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 cover the outside of the level body 4, it is convenient to protect the level body 4 when it is not suitable.

[0028] In one embodiment of the present invention, a waterproof layer is provided at the connection between the first protective cover 704 and the second protective cover 705 and at the outer surfaces of the first protective cover 704 and the second protective cover 705.

[0029] In one 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, a connecting plate 802 is fixedly installed on the front end of the connecting rod 801, and a protective cover 803 is fixedly installed on the bottom of the connecting plate 802. The eyepiece protection assembly 8 is provided on the front side of the first protective cover 704, and when the level body 4 is not needed, the eyepiece on the level body 4 is covered with the protective cover 803 to protect the eyepiece, thereby preventing the eyepiece from being damaged by external collision.

[0030] In one 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 body 4, and a sponge layer is provided on the contact surface between the protective cover 803 and the eyepiece. The protective cover 803 is released from the eyepiece by the sponge layer, thereby reducing the friction between the protective cover 803 and the eyepiece when rotating, thereby avoiding the wear of the eyepiece.

[0031] Working principle: When using the device, the level base 1 is fixed on the top of the bracket seat 5 by external bolts, and the level body 4 is calibrated by the foot screw 2. When the foot screw 2 is rotated to drive the adjusting column 3 to move upward, so as to adjust the position of the level body 4, the foot screw 2 drives 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 base 1. Since the inner cavity of the second gear 602 is provided with a threaded rod 604, the second gear 602 is threadedly connected with the threaded rod 604, thereby driving the movable hole 606 to rotate downward, so that the lower part of the movable hole 606 enters the inner cavity of the fixed hole 603 and is connected thereto, so that the level base 1 and the bracket seat 5 are connected. On the basis of the original bolt fixation between the level base 1 and the bracket seat 5, the threaded rod 604 is used to connect with the bracket seat 5, thereby improving the stability of the connection between the level base 1 and the bracket seat 5. At this time, since the adjusting column 3 moves upward, the bottom of the adjusting column 3 is separated from the top of the fixing plate 706, and the restriction on the first protective cover 704 and the second protective cover 705 is released, so that the second protective cover 705 and the first protective cover 704 can be opened upward by the return spring 703, and the first protective cover 704 and the second protective cover 705 are opened on the top of the level meter body 4. The material of the first protective cover 704 and the second protective cover 705 and the waterproof layer on the surface can be used to insulate the level meter body 4 from heat and rain. When the second protective cover 705 rotates upward, the protective cover 803 is driven to rotate, so that the protective cover 803 is separated from the level body 4, and the eyepiece on the level body 4 is exposed for easy use; After the use of the level body 4, the bolts connecting the level base 1 and the bracket seat 5 are unscrewed. When the foot screw 2 is not reset, the level base 1 and the bracket seat 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 opposite direction, using the first gear 601, the second gear 602 and the threaded rod 604, the threaded rod 604 is driven to move upward, so that the threaded rod 604 is separated from the fixing hole 603, thereby ensuring the reset of the foot screw 2 and facilitating the next use.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
