Abstract
Description
Technical Field
[0001] This application relates to the technical field of mass spectrometer installation, and in particular to an electrical equipment anti-misoperation interlocking device. Background Technology
[0002] Anti-misoperation interlocking devices are key equipment in power systems used to prevent electrical misoperation. Their core function is to meet the "five prevention" requirements, specifically including: preventing accidental opening and closing of circuit breakers; preventing opening and closing of disconnecting switches under load; preventing grounding wires from being connected while energized; preventing disconnecting switches with grounding wires connected; and preventing personnel from accidentally entering energized compartments. They are mainly used in the operation scenarios of power equipment such as circuit breakers and disconnecting switches. Through mechanical or electrical interlocking mechanisms, they prevent live operation, short circuit accidents, and personnel injuries caused by human error.
[0003] A search revealed Chinese Patent Publication No. CN222281814U, which discloses an electrical equipment anti-misoperation interlocking device, relating to the field of electrical safety technology. The device includes: a base plate; edge magnets and a central magnet fixedly connected to the lower part of the base plate; a protective cover fixedly connected to the middle part of the base plate; a receiving cavity at the lower part of the protective cover; an opening adapted to the receiving cavity at the lower part of the protective cover; a handle fixedly connected to the edge of the base plate; and a warning block fixedly connected to the upper part of the protective cover, with a warning symbol on its surface. The edge magnets and central magnets allow the base plate to be stably attached to the control panel of various electrical equipment; the protective cover protects push-button switches from accidental activation, increasing operational safety; and the warning block and warning symbol provide effective warnings.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Most existing anti-misoperation locking devices use keys for unlocking, but since keys are individual units, they are prone to being dropped or used by others, which can easily lead to misoperation. In addition, for some fingerprint-unlocked anti-misoperation locking devices, the fingerprint module is exposed to the outside, and prolonged exposure can easily cause damage. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses an electrical equipment anti-misoperation interlocking device. For example... Figure 1 and Figure 3 As shown, the lock includes a lock body 1, characterized in that: a fingerprint module 3 is fixedly installed on the inner wall of the lock body 1, the fingerprint module 3 is used to verify the biometric information of the operator to ensure that the permission is uniquely bound to the person, a protective component 2 is provided on the upper surface of the lock body 1, and a cleaning component 4 is provided on the inner wall of the protective component 2.
[0025] The protective component 2 includes a protective cover 25 and a groove 21. A plug plate 26 is fixedly installed on the lower surface of the protective cover 25, and a positioning hole is provided on the inner wall of the plug plate 26.
[0026] Please see Figure 3The upper surface of the lock body 1 is provided with a slot 5, and the insert plate 26 is adapted to the slot 5. The groove 21 is provided on the upper surface of the lock body 1. The fingerprint module 3 is located inside the protective cover 25. A fixing spring 22 is fixedly installed on the inner side wall of the groove 21. A lever 23 is fixedly installed at one end of the fixing spring 22. One end of the lever 23 extends to the outside of the groove 21. A positioning pin 24 is fixedly installed on the side wall of the lever 23. One end of the positioning pin 24 extends into the slot 5. One end of the positioning pin 24 is adapted to the positioning hole on the insert plate 26. The fixing spring 22 fixes the lever, ensuring the fixation of the positioning pin 24 in the positioning hole, further ensuring the fixation of the protective cover 25, and improving the fixation of the fingerprint module 3.
[0027] Please see Figure 3 The cleaning component 4 includes a connecting spring 41. One end of the connecting spring 41 is fixedly connected to the inner wall of the top surface of the protective cover 25, and the other end of the connecting spring 41 is fixedly mounted with a squeezing plate 42. A telescopic airbag 43 is fixedly mounted on the upper surface of the squeezing plate 42. The upper surface of the telescopic airbag 43 is fixedly connected to the inner wall of the top surface of the protective cover 25. An air outlet 44 is provided on the lower surface of the telescopic airbag 43, and a ventilation hole is provided on the lower surface of the squeezing plate 42. The ventilation hole and the air outlet 44 are connected to each other. The telescopic airbag 43 can rebound on its own, thereby ensuring that the telescopic airbag 43 automatically inflates each time the protective cover 25 is removed, making it convenient for the next use. The connecting spring 41 ensures that the squeezing plate 42 can rebound when the fingerprint module 3 is lost.
[0028] The implementation principle of the electrical equipment anti-misoperation interlocking device in this application embodiment is as follows: the lock body 1 is installed in an appropriate position by bolts, and then the fingerprint module 3 is used to identify and verify the identity of the operator. After the fingerprint module 3 is unlocked, the electrical equipment is prevented from being misoperated by the lock body 1. The lever 23 pulls one end of the positioning pin 24 out of the slot 5, and then the insert plate 26 is aligned with the slot 5 and inserted into the slot 5. At this time, the positioning hole is aligned with one end of the positioning pin 24. Under the action of the fixing spring 22, the lever 23 will drive the positioning pin 24 to insert into the positioning hole. The protective cover 25 is fixed by fixing the insert plate 26. At this time, the protective cover 25 covers the fingerprint module 3.
[0029] As the protective cover 25 moves toward the fingerprint module 3, the housing of the fingerprint module 3 will squeeze the extrusion plate 42. At this time, the extrusion plate 42 will squeeze the telescopic airbag 43 as it moves. The gas inside the extrusion airbag 43, which is squeezed, is blown toward the fingerprint module 3 through the air outlet 44 and the ventilation hole to clean the fingerprint module 3.
[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
