Embodiment 1

[0051] Please refer to figure 1 In this embodiment, a dual magnetic circuit sensor 100 is provided, which includes an I-shaped yoke 110 , two permanent magnets 120 , two winding supports 130 , two spring pieces 140 and a connecting rod 150 . The above-mentioned I-shaped yoke 110 forms two accommodating spaces, and the two permanent magnets 120 are respectively arranged in the above-mentioned two accommodating spaces, and the N pole of the permanent magnet 120 is in contact with the middle of the yoke 110, so that the yoke 110 as a whole becomes The N pole, the two ends of the yoke 110 are arranged opposite to the S pole of the corresponding permanent magnet 120, thereby forming a stable magnetic field. The winding supports 130 are respectively sleeved on the two permanent magnets 120 , and the coils are respectively wound on the two winding supports 130 . The end of the winding support 130 is connected with the end of the yoke 110 through the corresponding spring pieces 140 ;...

Embodiment 2

[0058] Please refer to figure 2 and image 3 This embodiment provides a control system 010 of a dual magnetic circuit sensor 100, which includes a valve 300, a memory (not shown in the figure), and the dual magnetic circuit sensor 100 provided in Embodiment 1. For the convenience of description, the two coils are named as the first coil 161 and the second coil 162 ; the first coil is connected to the memory, and the second coil is connected to the control device 200 . The valve is used to control the on-off of the pipeline, the memory is used to store the electromotive force signal of the first coil, and when the electromotive force of the second coil is large enough, it can drive the control device 200 to close the valve.

[0059] The above includes a valve body 310 and a valve core, the valve stem 310 is connected to the valve body through the valve core shaft; in the open state, the valve stem is arranged horizontally, and in the closed state, the valve stem is arranged v...

Abstract

The invention provides a control system with dual magnetic circuit sensors, which belongs to the field of earthquake protection. The above-mentioned control system is installed on the building, and the yoke is fixedly connected with the building. When an earthquake occurs, the vibration causes the first coil and the second coil to generate electromotive force; the memory collects the electrical signal for storage, and transmits it to the processor for analysis, thereby Obtain speed, acceleration and other data to provide a reliable basis for scientific research. When the earthquake intensity is high and the electromotive force of the second coil is high, it can make the electromagnet obtain magnetism, thereby causing the adsorption plate to move upward; the adsorption plate then drives the lever to swing, so that the connection between the abutting block and the pull rod is disconnected. At this time, the pulling rod can pull the valve stem to close under the action of the first spring, thereby cutting off the pipeline and reducing the possibility of fluid leakage in the pipeline.

Description

technical field [0001] The invention relates to the field of earthquake protection, in particular to a control system with dual magnetic circuit sensors. Background technique [0002] When a strong earthquake occurs, it will cause very serious damage to buildings; and at this time, if the pipeline transmission system is damaged, it will lead to leakage of fluid (eg natural gas), which may lead to more serious accidents. In addition, when an earthquake occurs, the relevant data (such as speed and acceleration) that cause building vibrations also have certain research value. Therefore, a control system is provided, which can cut off the transmission pipeline and record relevant data when the earthquake level is high, which is of great significance for scientific research and reduction of damage caused by earthquakes. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a control system with dual magnetic circuit sensors, which can cut off the...
