The structure of adjusting the level of existing optical level measuring instruments is relatively simple and is only suitable for working on relatively flat ground. When the ground is tilted too much or the ground is not flat enough, it is not easy for people to adjust the level of the optical level measuring instrument, which will further reduce the accuracy of the measurement results of the optical level measuring instrument.

There are three support and fixing assemblies, and the support and fixing assemblies are evenly distributed at equal angles with the support seat 13 as the center. The bottom of the support seat 13 is fixedly connected to a connecting block 15, and the outer wall of the connecting block 15 is fixedly connected to a gravity rope 16. The end of the gravity rope 16 away from the connecting block 15 is fixedly connected to a light-shielding shell 17, and the interior of the light-shielding shell 17 is fixedly connected to a photoresistor 18. The outer wall of the bottom of the light-shielding shell 17 is inlaid with a light-transmitting plate 19, and the outer wall of the top of the support seat 13 is inlaid with an S-pole magnet 20.

A level tube 27 is fixedly connected to one side of the top of the circular level 26, and a telescope 28 is fixedly connected to the top of the circular level 26. A coarse level light 29 is fixedly connected to one side of the outer wall of the support seat 13, and a button 30 is fixedly connected to the other side of the outer wall of the support seat 13. The telescope 28 is set in the center of the top of the circular level 26. The electromagnet 8, photoresistor 18, button 30, and control center are all electrically connected to the internal power supply 14, the button 30 is electrically connected to the electromagnet 8, and the direct light 6 is in a constantly on state.

[0031] By rotating the coarse adjustment threaded rod 2 and driving the elastic belt 4 to move under the action of the support frame 1, the movement of the elastic belt 4 drives and, under the action of the triangle plate 5, makes the direct lamp 6 correspond to the position of the light shielding shell 17, further enabling the present measuring instrument to work normally on the ground with a large inclination angle or low ground flatness. At the same time, it is also more convenient for engineers to adjust, so that the accuracy of the measurement results of the optical level measuring instrument is improved, and it can achieve the effect of being able to work on uneven ground and improving the accuracy of the measurement results of the optical level measuring instrument. By rotating the rotating shaft 7 and driving the iron ratchet rod 10 to rotate under the action of the electromagnet 8 and the spring 9, the iron ratchet rod 10 moves and cannot move in the opposite direction under the action of the ratchet 12 and the rebound force of the spring 9, making the present device more stable. When encountering strong winds during outdoor measurement, it is not easy to blow down the optical level measuring instrument, and it will not cause irreversible damage to the optical level measuring instrument, and it can achieve the effect of making the support of the optical level measuring instrument more stable.

[0032] Working principle: When using this optical level measuring instrument, the optical engineer first places the three supporting and fixing components of the device on the ground, and then grabs and rotates the support frame 1. The rotation of the support frame 1 drives the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 drives the electromagnet 8 to move. The rotation of the rotating shaft 7 drives the spring 9 to move under the action of the electromagnet 8. The rotation of the rotating shaft 7 drives the iron ratchet rod 10 to rotate around the ratchet 12 under the action of the spring 9. The movement of the iron ratchet rod 10 causes the spring 9 to deform under the action of the ratchet 12. At this time, the iron ratchet rod 10 cannot move in the opposite direction under the action of the ratchet 12 and the rebound force of the spring 9. Further, under the action of the rotating shaft 7, the support frame 1 cannot rotate in the opposite direction, making this device more stable.

[0033] At the same time, the support frame 1 rotates so that the elastic band 4 is tightened. When the optical engineer unfolds the support and fixing assembly, he finds that the coarse level light 29 is not on, indicating that the ground is not level. At this time, the optical engineer rotates the fixed cone 3. The rotation of the fixed cone 3 drives the coarse adjustment threaded rod 2 to rotate. The rotation of the coarse adjustment threaded rod 2 drives the support frame 1 to extend or shorten. The extension or shortening of the support frame 1 causes the level of the support seat 13 to be adjusted. At the same time, the extension or shortening of the support frame 1 drives the elastic band 4 to move. The movement of the elastic band 4 drives the movement of the triangle 5. The movement of the triangle 5 drives the direct lamp 6 to move. When the direct lamp 6 moves to the position corresponding to the light-shielding shell 17, the light emitted by the direct lamp 6 passes through the light-transmitting plate 19 and illuminates the outside of the photoresistor 18. The light received by the photoresistor 18 becomes stronger, the resistance value becomes smaller, and the current becomes larger. At this time, the control center senses this current change and controls the internal power supply 14 to power the coarse level light 29. The coarse level light 29 is powered on and lights up. At this time, the optical engineer stops rotating the fixed cone 3 and makes the support seat 13 horizontal.

[0034] Next, the optical engineer inserts the six-sided clamping column 23 into the support base 13. At the same time, the S-pole magnet 20 and the N-pole magnet 22 attract each other so that the base 21 and the support base 13 are adsorbed and fastened. At this time, the operator observes whether the small bubble inside the level tube 27 is in the center. If not, the optical engineer turns the fine-tuning screw 24. The rotation of the fine-tuning screw 24 drives the fine-tuning threaded rod 25 to rise or fall. The movement of the fine-tuning threaded rod 25 adjusts the level of the circular level 26 until the small bubble inside the level tube 27 is in the center position and the fine-tuning screw 24 is stopped to complete the level adjustment.

[0035] When the operator finishes using the optical level meter, he presses the button 30. The internal power supply 14 then supplies power to the electromagnet 8. The electromagnet 8 becomes magnetic when energized and attracts the iron ratchet 10 to slide. The sliding of the iron ratchet 10 compresses the spring 9. The sliding of the iron ratchet 10 no longer engages with the ratchet 12, and the movement of the rotating shaft 7 is no longer restricted. The movement of the rotating shaft 7 is no longer restricted. At this time, the elastic band 4 drives the support frame 1 to move under the action of its rebound force. The movement of the support frame 1 drives the rotating shaft 7 to rotate. Similarly, the three supporting and fixing components are retracted.
