Abstract

The utility model discloses a large-caliber anti-drop and anti-shake magnetic compensator which comprises a swing piece set and a mounting base, the mounting base is provided with a slot, the swing piece set is of a U-shaped structure, the top of the swing piece set extends into the mounting base through the slot and is connected with the mounting base through a screw, and the swing piece set is symmetrically provided with two through grooves. Two hanging springs are arranged in each through groove in a crossed mode. The magnet is located above the damping plate, and the damping plate is made of copper materials, so that magnetism exists between the damping plate and the magnet. When the swinging piece set shakes, according to the Lenz's law, the conductor moves in the magnetic field and cuts the magnetic induction lines, and electromotive force is generated in the conductor.

And meanwhile, through the magnetic connection relation, shaking during angle deviation can be reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of anti-shake compensators, in particular to a large-aperture anti-drop and anti-shake magnetic compensator. Background Technique

[0002] A level is a measuring tool used to measure the elevation difference of the ground. However, during the measurement process, due to various factors such as temperature, atmospheric pressure, and the structure of the level itself, errors may occur in the level. A level compensator is an auxiliary tool specifically used to correct these errors and improve the accuracy and precision of the measurement.

[0003] When the current compensators are in use, if the external environment changes, such as the ground vibration caused by a passing car, this vibration will be transmitted into the level, generating huge vibrations, which seriously affect the observation effect. In some cases, it is even necessary to recalibrate the level, greatly affecting the efficiency and accuracy of the measurement work.

[0004] The seismic resistance effect of the magnetic compensator is not obvious under small vibrations, but under large vibrations, due to the action of Lenz's law, the damping effect is significant.

[0005] Based on this, the technicians in this field have proposed a large-aperture anti-drop and anti-shake magnetic compensator. Content of the Utility Model

[0006] The utility model discloses a large-aperture anti-drop and anti-shake magnetic compensator, aiming to solve the technical problems in the background technique.

[0007] To achieve the above object, the utility model adopts the following technical solutions:

[0008] The large-aperture anti-drop and anti-shake magnetic compensator includes a pendulum assembly and a mounting base. A slot is provided on the mounting base. The pendulum assembly is arranged in a U-shaped structure. The top of the pendulum assembly extends into the interior of the mounting base through the slot and is connected by screws. Two through slots are symmetrically provided on the pendulum assembly. Two suspension wires are cross-arranged inside each through slot. Pressure plates are connected to the pendulum assembly and the mounting base by screws. Both ends of the suspension wires are connected to the pendulum assembly and the mounting base through the pressure plates. A connecting arm is fixedly connected to the outside of the mounting base. A connecting rod is fixedly connected to the pendulum assembly. The connecting rod is connected to the connecting arm. A U-shaped support frame is fixedly connected to the connecting rod. A magnet is fixedly connected to the support frame. A sink is provided at the bottom of the pendulum assembly. A damping plate is connected to the bottom of the pendulum assembly by screws. The support frame is arranged outside the damping plate.

[0009] The mounting base is used to mount the surveying instrument, and the ornament group is connected to the mounting base by a hanging wire. However, the hanging wire is made of metal material. Therefore, the hanging wire does not need to be hoisted on the mounting base to complete the connection. In this way, the ornament group can rotate. Since the magnet is located above the damping plate and the damping plate is made of copper, there is magnetism between the damping plate and the magnet. When the ornament group shakes, the magnet and the damping plate will reduce the shake through magnetic connection, which can effectively reduce the shake of the ornament group, thereby reducing the shake amplitude of the whole device and improving the surveying accuracy.

[0010] In a preferred solution, a placement groove is formed inside the connecting arm. A roof prism is placed inside the placement groove. The roof prism extends into the placement groove. The roof prism is connected to the connecting arm by screws. Inside the ornament group and below the roof prism, a trapezoidal prism is connected by screws. A temperature adjustment piece is connected to the top of the ornament group by screws. The temperature adjustment piece can rotate. Connecting shafts are symmetrically and fixedly connected to the outside of the ornament group. Connecting pieces are symmetrically connected to the outside of the mounting base by screws. The connecting pieces are rotatably connected to the corresponding connecting shafts.

[0011] By setting the connecting shafts, the ornament group can rotate around the connecting shafts as the center, so as to achieve the rotation effect of the ornament group. However, such a rotation effect will drive the hanging wire when rotating. The hanging wire can play a first-level alleviating role, enabling the ornament group to rotate but at the same time limiting the ornament group. Then, through the magnetic connection between the magnet and the damping plate, the offset angle is corrected, and at the same time, the shake during angle offset can be reduced through the magnetic connection relationship.

[0012] The large-aperture anti-drop and anti-shake magnetic compensator provided by the present utility model has the following advantages:

[0013] In the present utility model, the magnet is located above the damping plate, and the damping plate is made of copper material. Therefore, there is magnetism between the damping plate and the magnet. When the ornament group shakes, 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, and the magnetic field generated by this current will hinder this relative movement, thereby playing a shock-absorbing role for the air magnetic piston and correcting the offset angle. At the same time, through the magnetic connection relationship, the shake during angle offset can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Usually, the components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0024] The large-aperture anti-drop and anti-shake magnetic compensator disclosed by the present utility model.

[0025] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in Figure 5 , Figure 6 , Figure 7 and Figure 8 , the large-caliber anti-drop and anti-shake magnetic compensator includes a display group 1 and an installation base 2. A slot 3 is opened on the installation base 2. The display group 1 is set in a U-shaped structure. The top of the display group 1 extends into the interior of the installation base 2 through the slot 3 and is connected by screws. Two through slots 4 are symmetrically opened on the display group 1. Two suspension wires 5 are cross-arranged inside the through slots 4. Pressure plates 6 are connected to both the display group 1 and the installation base 2 by screws. Both ends of the suspension wires 5 are connected to the display group 1 and the installation base 2 through the pressure plates 6. A connecting support arm 9 is fixedly connected to the outside of the installation base 2. A connecting rod 10 is fixedly connected to the display group 1. The connecting rod 10 is connected to the connecting support arm 9. A U-shaped support frame 11 is fixedly connected to the connecting rod 10. A magnet 12 is fixedly connected to the support frame 11. A sunk groove 7 is opened at the bottom of the display group 1. A damping plate 8 is connected to the bottom of the display group 1 by screws. The support frame 11 is arranged outside the damping plate 8;

[0026] In this embodiment: The installation base 2 is used to install surveying and mapping instruments, and the display group 1 is connected to the installation base 2 through the suspension wires 5. However, the suspension wires 5 are made of metal. Therefore, the suspension wires 5 do not need to be hoisted on the installation base 2 to complete the connection. In this way, the display group 1 can rotate. Since the magnet 12 is located above the damping plate 8 and the damping plate 8 is made of copper, there is magnetism between the damping plate 8 and the magnet 12. In this way, when the display group 1 shakes, the magnet 12 and the damping plate 8 will reduce the shake through magnetic connection, which can effectively reduce the shake of the display group 1, thereby reducing the shake amplitude of the entire device and improving the surveying and mapping accuracy.

[0027] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , in a preferred embodiment, a placement groove 13 is opened inside the connecting support arm 9. A roof prism 14 is placed inside the placement groove 13. The roof prism 14 extends into the interior of the placement groove 13. The roof prism 14 is connected to the connecting support arm 9 by screws. A trapezoidal prism 15 is connected to the inside of the display group 1 and below the roof prism 14 by screws. A temperature adjustment piece 16 is connected to the top of the display group 1 by screws. The temperature adjustment piece 16 can rotate. Connecting shafts 17 are symmetrically and fixedly connected to the outside of the display group 1. Connecting pieces 18 are symmetrically connected to the outside of the installation base 2 by screws. The connecting pieces 18 are rotatably connected to the corresponding connecting shafts 17;

[0028] In this embodiment: By providing the connecting shaft 17, the ornament group 1 can rotate around the connecting shaft 17, thus achieving the rotation effect of the ornament group 1. However, such a rotation effect will drive the suspension wire 5 during rotation. The suspension wire 5 can play a first-level buffering role, enabling the ornament group 1 to rotate while also limiting the movement of the ornament group 1. Subsequently, through the magnetic connection between the magnet 12 and the damping plate 8, the offset angle is corrected, and at the same time, the magnetic connection can reduce the wobbling during angle offset.

[0029] Working principle: During use, the mounting base 2 is used to mount the surveying instrument, and the ornament group 1 is connected to the mounting base 2 through the suspension wire 5. However, the suspension wire 5 is made of metal. Therefore, the suspension wire 5 does not need to be suspended on the mounting base 2 to complete the connection. By providing the connecting shaft 17, the ornament group 1 can rotate around the connecting shaft 17, thus achieving the rotation effect of the ornament group 1. However, such a rotation effect will drive the suspension wire 5 during rotation. The suspension wire 5 can play a first-level buffering role, enabling the ornament group 1 to rotate while also limiting the movement of the ornament group 1. In this way, the ornament group 1 can rotate. Since the magnet 12 is located above the damping plate 8 and the damping plate 8 is made of copper, there is magnetism between the damping plate 8 and the magnet 12. Thus, when the ornament group 1 wobbles, the offset angle is corrected through the magnetic connection between the magnet 12 and the damping plate 8, and at the same time, the magnetic connection can reduce the wobbling during angle offset.

The substitution may be a substitution of some structures, devices, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
