[0030] The present invention will be further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0031] Example

[0032] In the field of dual-center mixing equipment technology, excessive vibration of the equipment will make the mixing equipment unable to operate normally, and the vibration will have a fatal impact on the mixing quality of the composite materials being mixed. In order to obtain better mixed composite materials, it is necessary to ensure that the mixing equipment runs more smoothly. The composite materials can be degassed and mixed in a stable environment so that they can be more fully ground and finely ground.

[0033] Therefore, it is necessary to monitor the vibration of the equipment and understand the vibration of the equipment in real time. In previous equipment, the vibration of the equipment was usually observed by naked eyes and felt by hand when the equipment was running. However, these methods cannot obtain the data of the equipment vibration, and they cannot determine the direction of the equipment vibration. Due to the lack of accurate vibration data analysis and the inability to determine the direction of the equipment vibration, there is blindness in the equipment shock absorption adjustment process, so a lot of time is needed to test and check the direction and cause of the swing, which greatly prolongs the production and maintenance cycle of the equipment.

[0034] In order to solve the above problems, Figure 1-Figure 5 As shown, this embodiment provides a multi-angle vibration sensor, including:

[0035] A housing 1, wherein the housing is provided with electrodes;

[0036] An insulating seat body 2, the insulating seat body is connected to the shell, and the insulating seat body and the shell are surrounded to form a cavity 3;

[0037] A connector 4, which is disposed in the cavity, one end of which is connected to the housing, and which is electrically conductive and connected to the electrode;

[0038] A swinging member 5, the swinging member is located in the cavity, the swinging member is conductive, the swinging member is connected to the other end of the connecting member so that the swinging member is suspended in the air under the action of gravity, the swinging member can swing when vibrating, the swinging member has a minimum swing radius and a minimum swing circle, and in a stable state, the swinging member is located at the center of the minimum swing circle;

[0039] A plurality of conductive sheets 6, each of which is respectively arranged on the insulating seat, each of which is at least partially located in the cavity, and each of which is respectively distributed along the minimum swing circle;

[0040] The electrodes and the conductive sheets are electrically connected to an external control device, and the swinging member can contact at least one of the conductive sheets when vibrating, so that the electrodes, the connecting member, the swinging ball, the conductive sheet and the external control device form a closed loop.

[0041] The multi-angle vibration sensor of this embodiment is placed on the equipment. When the equipment runs smoothly without swinging, the swinging part is located at the center of the minimum swinging circle. When the equipment runs unsteadily and swings, the multi-angle vibration sensor will swing with the equipment, driving the swinging part to swing in the direction of the equipment swinging. The swinging part collides with at least one conductive sheet due to the swinging, so that the electrode, the connecting part, the swinging ball, the conductive sheet hit by the swinging ball and the external control device form a closed loop to generate an impact signal. The external control device records the impact signal and obtains the vibration data of the equipment. According to the impact signal, the position of the conductive sheet hit by the swinging ball can be known, thereby knowing the vibration position of the equipment. The multi-angle vibration sensor of this embodiment can be used to detect whether there is a problem in the assembly of the shock absorbing device of the equipment, thereby improving the efficiency of equipment assembly and ensuring the quality of equipment assembly.

[0042] In some embodiments, the insulating base body is made of insulating bakelite. In other embodiments, the insulating base body may also be made of plastic or ceramic. As long as it is an insulating material, no further details are given here.

[0043] In some embodiments, the connecting member is a suspension spring. In other embodiments, the connecting member may also be a steel wire rope, which will not be listed in detail here.

[0044] In some embodiments, the swinging member is a steel ball, which can ensure a relatively stable swing. In other embodiments, swinging members of other shapes can also be used, such as square, cylindrical or diamond shapes, etc., as long as the swinging member can ensure contact with the conductive sheet, and no excessive restrictions are made here.

[0045] In some embodiments, Figure 3 As shown, one end of the connecting piece is connected to the center of the top surface of the shell, so as to fully utilize the space inside the shell and reduce the volume of the shell.

[0046] In some embodiments, the cavity is a vacuum cavity. The vacuum environment can make the swinging member swing without resistance and reduce the weakening of current transmission.

[0047] In some embodiments, the shell is provided with an air inlet and an air extraction hole (not shown), the air extraction hole is used to extract the air in the cavity, and the air inlet is used to allow external gas to enter the cavity after the detection is completed.

[0048] In other embodiments, an air inlet and an air extraction hole (not shown) may be provided on the insulating base. The air extraction hole is used to extract the air in the cavity, and the air inlet is used to allow external gas to enter the cavity after the detection is completed.

[0049] In some embodiments, the shell is an insulating shell, and the electrode is an electrode wire (not shown) printed on the inner wall of the shell. In this way, the space occupied by the electrode in the cavity can be reduced, and the electrode can be prevented from interfering with the swing of the swing member.

[0050] In some embodiments, the housing is a glass housing so that the swinging process of the swinging member can be observed.

[0051] In other embodiments, the shell may also be a metal shell, and the electrode does not contact the shell, or the electrode is wrapped with insulating material, as long as it does not affect the swing of the swing member, and no excessive restrictions are made here.

[0052] In some embodiments, the plurality of conductive sheets are copper sheets of the same size. In other embodiments, iron sheets or silver sheets may also be used. No further examples are given here.

[0053] In some embodiments, the plurality of conductive sheets are equidistantly distributed along the minimum swing circle. In this way, the number and spacing of the conductive sheets can be set according to the required detection accuracy requirements.

[0054] In some embodiments, the number of the conductive sheets is four, six, eight or sixteen. The number and orientation of the conductive sheets can be set according to the requirements of detection accuracy and are not limited here.

[0055] In this embodiment, if Figure 4 and Figure 5As shown, there are eight conductive sheets, and with the swinging member in a stable state as the center, the eight conductive sheets are respectively located in the due east, due north, due south, due west, northeast, northwest, southwest and southeast directions of the swinging member. For example, when the swinging member contacts the conductive sheet in the due east direction, the connecting member, the swinging ball, the electrode, the conductive sheet and the external control device form a closed loop to generate an impact signal. The external control device records the impact signal and obtains the vibration data of the device. According to the impact signal, the position of the conductive sheet hit by the swinging ball can be known, thereby obtaining the vibration position of the device. By displaying the impact signal, the shock absorbing device at the position of the device can be checked to determine the cause of the vibration of the device.

[0056] In some embodiments, Figure 3 As shown, in a stable state, the vertical projection of the swing member and the vertical projection of the conductive sheet at least partially overlap, so as to ensure that the swing member can contact the conductive sheet when swinging.

[0057] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the multi-angle vibration sensor also includes a female socket 7 and a plurality of pins 8, the plurality of pins are connected to the insulating seat body, and the plurality of pins correspond to the plurality of conductive sheets one by one; the pins are connected to the conductive sheets, and the female socket is provided with a plurality of corresponding jacks 71, and the plurality of pins can be correspondingly plugged into the plurality of jacks, and the female socket is electrically connected to an external control device. The external control device supplies power to the conductive sheet and the electrode through the female socket, which simplifies the circuit design in the insulating seat body and facilitates reducing the overall volume of the insulating seat body.

[0058] In some embodiments, Figure 6 As shown, the female base is provided with a signal interface 72, and the signal interface is electrically connected to an external control device, thereby realizing information interaction between the multi-angle vibration sensor and the external control device.

[0059] In some embodiments, Figure 3 and Figure 5 As shown, the multi-angle vibration sensor also includes an insulating fixing 9, which is located in the cavity and connected to the plurality of conductive sheets. One end of the plurality of conductive sheets is respectively connected to the insulating seat, and the other end passes through the insulating fixing. The end of the conductive sheet away from the insulating seat is used to contact the swinging member. By providing the insulating fixing, when the conductive sheet is long, the conductive sheet can be reinforced to avoid deformation and displacement caused by the swinging member after long-term use, thereby affecting the generation of the impact signal.

[0060] In some embodiments, the insulating fixing member is made of plastic. In other embodiments, the insulating fixing member may also be made of wood or ceramic materials, which are not listed in detail here.

[0061] In some embodiments, the insulating fixing member is cylindrical, and in other embodiments, the insulating fixing member may also be annular, as long as it can reinforce the conductive sheet, and there is no limitation here.

[0062] In some embodiments, the external control device is a dual-center stirring device, and the multi-angle vibration sensor is installed in the dual-center stirring device or placed on the device, fixed to the dual-center stirring device through a mother seat, and information is exchanged with the dual-center stirring device through a signal interface. After starting the dual-center stirring device, when the device runs smoothly without swinging, the swinging member is at the center of the minimum swinging circle. When the device runs unsteadily and swings, the swinging member will swing in the direction of the device's swinging. The swinging member will hit the conductive sheet in a certain direction due to the swinging, forming a closed loop to generate an impact signal, which will be transmitted to the dual-center stirring device through the signal interface, and the impact direction will be displayed on the display of the device as an alarm. Through the display of the impact signal, the shock absorbing device in the position of the device can be checked to determine the cause of the vibration of the device.

[0063] The multi-angle vibration sensor of this embodiment can monitor the dual-center mixing equipment in real time and understand the real-time status of the equipment's shock-absorbing device in real time. It can avoid the quality impact of the stirred product caused by damage to the equipment's shock-absorbing device, and also provide powerful assistance for vibration maintenance. For dual-center mixing equipment that is being assembled, it can be used to detect whether there are any problems with the equipment's shock-absorbing device assembly, thereby improving the efficiency of equipment assembly and ensuring the quality of equipment assembly.
