Description

Technical Field

[0001] The utility model relates to the technical field of measurement compensators, in particular to a pneumatic and magnetic double-damping compensator. Background Technique

[0002] A level is a tool used to measure the elevation difference of the ground. During the measurement process, due to factors such as temperature, atmospheric pressure, and the structure of the level itself, measurement errors may occur. To correct these errors and improve the measurement accuracy and precision, a compensator for the level has emerged.

[0003] Currently, compensators mainly use pneumatic compensation structures or magnetic compensation structures for calibration. The pneumatic compensator has a significant effect during small jitters, but it takes a long time to return to zero during large vibrations. The magnetic compensator has an insignificant anti-vibration effect under small vibrations, but during large vibrations, due to the action of Lenz's law, the damping effect is significant. Generally speaking, the pneumatic compensation and magnetic compensation structures have their own advantages and disadvantages and complement each other.

[0004] Based on this, those skilled in the art have proposed a pneumatic and magnetic double-damping compensator, which combines the advantages of pneumatic compensation and magnetic compensation structures to provide a more comprehensive error correction ability. Content of the Utility Model

[0005] The utility model discloses a pneumatic and magnetic double-damping compensator, aiming to solve the technical problems in the background technique.

[0006] To achieve the above object, the utility model adopts the following technical scheme:

[0007] A pneumatic and magnetic double-damping compensator includes a main frame and a connecting frame. The connecting frame is fixedly connected to the bottom of the main frame. The inside of the connecting frame is a hollow structure and is provided with a pendulum assembly. A pneumatic and magnetic piston is fixedly connected inside the pendulum assembly. Magnets are symmetrically and slidably connected inside the pneumatic and magnetic piston. A through groove is opened inside the connecting frame, and a pneumatic and magnetic cylinder head is movably connected inside the through groove. Installation grooves are symmetrically opened inside the pneumatic and magnetic piston, and the pneumatic and magnetic cylinder heads extend into the corresponding installation grooves.

[0008] The magnet is placed inside the pneumatic and magnetic piston through the pneumatic and magnetic cylinder head. The magnet is tightly connected to the pneumatic and magnetic piston, and the pneumatic and magnetic piston is made of copper. Using the principle of Lenz's law, the pneumatic and magnetic piston is thus shock-absorbed. And when the pneumatic and magnetic cylinder head is sealed, there will also be gas inside the pneumatic and magnetic piston. When the pneumatic and magnetic piston moves, the gas pressures on both sides are different, which will also have a shock-absorbing effect on the pneumatic and magnetic piston.

[0009] In a preferred embodiment, two fixing grooves are symmetrically formed on the outer side of the connecting frame. Fastening strips are movably connected inside the fixing grooves. The fastening strips are connected to the fixing grooves by screws. The fastening strips are in contact with the corresponding pneumatic magnetic cylinder covers. Four pressing blocks are symmetrically connected to the ornament set and the main frame by screws respectively. A suspension wire is connected between each pair of corresponding pressing blocks. Each pair of corresponding suspension wires is arranged in a cross structure. The top of the main frame is connected with a prism mounting set by screws. A fixed prism is fixedly connected to the bottom of the prism mounting set. A substrate-free swing mirror gluing set is fixedly connected to the bottom of the prism mounting set and below the fixed prism. An inclined prism is fixedly connected to one side of the main frame. A swing body is fixedly connected to the bottom of the ornament set. The outer side of the connecting frame is symmetrically connected with connecting plates by screws. The connecting plates are rotationally connected with the ornament set.

[0010] The connecting plate enables the ornament set to have a rotating function. The suspension wire is made of metal material, so that the ornament set has a limiting function. When the ornament set rotates, it can drive the pneumatic magnetic piston to shake. Through such a setting, the ornament set can perform shaking compensation, and through such a setting, the main frame and the connecting frame can be vibration-damped and compensated.

[0011] A pneumatic magnetic double-damping compensator provided by the present invention has the following advantages:

[0012] In the present invention, the magnet is placed inside the pneumatic magnetic piston and fixed by the pneumatic magnetic cylinder cover. The magnet is tightly connected to the copper pneumatic magnetic piston. According to Lenz's law, when a conductor moves in a magnetic field and cuts the magnetic induction line, an electromotive force will be generated in the conductor. If the conductor moves relative to the magnetic pole, an induced current will be generated in the closed conductor. The magnetic field generated by this current will hinder this relative movement, thus playing a damping role on the pneumatic magnetic piston. In addition, when the pneumatic magnetic cylinder cover is sealed, there will also be gas inside the pneumatic magnetic piston. When the pneumatic magnetic piston moves, the gas pressures on both sides are different, further playing a damping effect on it. Through this design, the ornament set can not only perform shaking compensation, but also be damped through the combined action of magnetism and gas. Compared with the traditional single mode, the present application is more stable and has better effects. BRIEF DESCRIPTION OF THE DRAWINGS
