AI Technical Summary
In the vertical line measurement, the lack of energy consumption mechanism, the swing consumes mechanical energy slowly. The larger and heavier the line fall, the longer the vertical distance, the longer it needs to wait for it to stop swinging.
An electromagnetic energy-consuming wire sinker is designed, including steel cones, copper tubes, permanent magnets, springs and perpendicular wires. The permanent magnet in the copper tube is hung by a spring, and the south pole and the north pole of the permanent magnet are aligned at both ends of the copper tube, and the upper end of the spring is connected to the perpendicular line. The design consumes the mechanical energy of the permanent magnet through the ring-shaped induced current in the copper tube, and converts the electrical energy into heat through the resistance of the copper tube, quickly stopping the swing of the wire drop.
By converting the mechanical energy of the line sink into electrical energy and then converting it into thermal energy, the swing time of the line sink is significantly shortened, and a perpendicular line is quickly provided as a measurement reference, reducing the interference of external factors such as wind power to the line sink.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of wood-penetrating engineering, in particular to an electromagnetic energy-consuming plumb bob. Background Art
[0002] A plumb line is often used in civil engineering construction to provide a vertical line, which is used as a reference for measuring and inspecting buildings. The plumb line is a thin soft line with a conical weight attached to its lower end. When using the plumb line, the upper end of the thin soft line is connected to a high place, and the conical weight hangs below and swings freely. When the swing stops, the thin soft line becomes a vertical line.
[0003] Because the plumb line itself lacks an energy-dissipating mechanism, the mechanical energy of the plumb line's swing is consumed slowly. Moreover, the larger and heavier the plumb line is, and the longer the vertical distance is, the longer it takes to wait for it to stop swinging. Utility Model Content
[0004] The utility model aims to overcome the defects of the prior art and provide an electromagnetic energy-consuming line sinker.
[0005] In order to solve the above technical problems, the utility model is achieved as follows:
[0006] An electromagnetic energy-dissipating plumb bob is characterized in that it comprises a steel cone, a copper tube, a permanent magnet, a spring and a plumb line; the copper tube is vertically arranged, and its lower part is fixedly connected to the steel cone; a permanent magnet suspended by a spring is arranged in the copper tube, and the south pole and north pole of the permanent magnet face the two ends of the copper tube, and the upper end of the spring is connected to the plumb line.
[0007] The electromagnetic energy-consuming plumb bob is characterized in that: the outer ring of the lower part of the copper tube is provided with an outer thread, the inner ring of the steel cone is provided with an inner thread matching the outer thread of the outer ring of the copper tube, and the copper tube and the steel cone are screwed and connected by the thread.
[0008] The electromagnetic energy-consuming plumb bob is characterized in that a plastic cover is installed on the top of the copper tube, a hole is opened in the middle of the plastic cover, and the vertical line passes through the hole to connect to the spring.
[0009] The electromagnetic energy-dissipating plumb bob is characterized in that heat sinks are provided on both sides of the upper portion of the copper tube.
[0010] The beneficial effects of the utility model are as follows: It can be seen from the above technical solution that the present application provides an electromagnetic energy-consuming plumb bob, which converts the mechanical energy of the plumb bob swinging into electrical energy first and then into heat energy, so that the plumb bob stops swinging quickly. The bottom of the plumb bob is a steel cone, and a copper tube is inserted and fixed in the upper part of the steel cone. A permanent magnet is suspended inside the copper tube using a small elastic modulus helical spring, and the center of the top of the copper tube is connected to a thin soft wire.
[0011] When the plumb line swings to the lowest position (when the angle with the vertical line is the smallest), the spring elongation is the largest, and when it swings to the highest position (when the angle with the vertical line is the largest), the spring elongation is the smallest. During the swing cycle, the permanent magnet reciprocates in the copper tube. For a section of the copper tube near the position of the permanent magnet, the magnetic flux in its closed circular cross-section changes with the reciprocating motion of the permanent magnet, and then a circular induced current is generated in the copper tube to resist the change in magnetic flux, thereby causing the copper tube to heat up. During the whole process, the mechanical energy of the plumb line swing is converted into thermal energy of the copper tube, thereby causing the plumb line to stop swinging as soon as possible.
[0012] The application is simple and convenient to operate, shortens the swing time of the plumb line, and quickly provides a vertical line as a measurement reference; it reduces the interference of external factors such as wind on the vertical line. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:
[0014] Figure 1 This is a schematic diagram of the structure of this application. DETAILED DESCRIPTION
[0015] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application.
[0016] like Figure 1 As shown: an electromagnetic energy-absorbing plumb bob, which comprises a steel cone 1, a copper tube 2, a permanent magnet 3, a spring 4 and a plumb line 5; the copper tube is vertically arranged, and its lower part is fixedly connected to the steel cone, and there is a permanent magnet suspended by a spring in the copper tube, and the south pole and north pole of the permanent magnet are opposite to the two ends of the copper tube, and the upper end of the spring is connected to the plumb line.
[0017] The outer ring of the lower part of the copper tube is provided with an outer thread, and the inner ring of the steel cone is provided with an inner thread matching the outer thread of the outer ring of the copper tube. The copper tube and the steel cone are screwed together through the thread 6.
[0018] A plastic cover 7 is installed on the top of the copper tube, a hole is opened in the middle of the plastic cover, a vertical line passes through the hole to connect the spring, and the plastic cover and the copper tube are connected by a threaded connection 10.
[0019] Heat sinks 8 are provided on both sides of the upper part of the copper tube.
[0020] A permanent magnet is hung inside the copper tube by a small elastic modulus spring. When the copper tube is in an upright equilibrium state, the permanent magnet is in the center of the copper tube. A perforated plastic cover is set at the top of the copper tube and is screwed and connected by a thread. A thin soft wire is inserted into the middle hole of the plastic cover to set a knot 9, so that the whole pendant can be hung.
[0021] When setting the pendant, fix the top of the thin soft line at a fixed point, hold the cone to make the thin soft line as close to vertical as possible, and then release it naturally. During the swing of the pendant, its mechanical energy will be converted into electrical energy and heat energy and dissipated, thereby shortening the swing time of the pendant. The position of the thin soft line after the swing stops is the vertical line.
[0022] Specifically, during the swing of the permanent magnet with the plumb line, the centripetal force is provided by the combined force of the spring tension and gravity. The spring elongation is the largest when it swings to the bottom, and the smallest when it swings to the top. During the swinging process, the permanent magnet reciprocates relative to the copper tube in the copper tube, and the magnetic flux passing through the closed conductor in a certain interface of the copper tube changes, generating a circular induced current I on the cross section of the copper tube. According to Lenz's law, the magnetic field generated by the circular induced current I in a section of the copper tube behind the permanent magnet is in the same direction, and the magnetic field generated by the circular induced current I in a section of the copper tube in front of the permanent magnet is in the opposite direction. The magnetic force of the induced current magnetic field on the permanent magnet does negative work on the reciprocating permanent magnet, consuming its mechanical energy. Since the permanent magnet swings with the plumb line, the mechanical energy of the permanent magnet is reduced and a force is generated between the copper tube arm and the arm along the swing tangent direction, doing negative work on the entire plumb line except the permanent magnet, that is, consuming the mechanical energy of other parts of the plumb line to supplement the mechanical energy of the permanent magnet, and then converting it into the electrical energy of the induced current I. Since the resistance R of the copper tube is not 0, the current causes the copper tube to heat up, and the heating power P=I 2 R, the electrical energy of the induced current is converted into heat energy.
[0023] Furthermore, the bottom of the plumb line is a steel cone, and a copper tube is inserted and fixed in the upper part of the steel cone. A permanent magnet is suspended inside the copper tube using a small elastic modulus helical spring, and the center of the top of the copper tube is connected to a thin soft wire.
[0024] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
