[0002] The electrical cabinet is a device for protecting the normal work of components, which is mainly composed of a shell, a steel structure, various mounting plates, components, instruments, measurement and control devices, and cables. Periodic leakage detection of the electrical cabinet can timely discover and handle potential leakage hazards, thereby effectively preventing the occurrence of electrical fire.

[0003] At present, in the process of leakage detection of the electrical cabinet, a technician generally holds a leakage detector with one hand and contacts the detection contact of the detector with the detection part of the electrical cabinet with the other hand, and detects the leakage of the electrical cabinet at this position through the data change of the detector. However, when detecting the leakage inside the electrical cabinet, it is not easy to move the detector in the electrical cabinet due to the limited space inside the electrical cabinet, and the hand is directly in contact with the electrical cabinet during the detection process, which has certain leakage safety hazards. CONTENT OF THE UTILITY MODEL

[0007] Preferably, the dial mechanism comprises a damping shaft arranged on the insulating rod, and a rotating frame rotatably connected to the outer surface of the damping shaft. The dial mechanism can adjust the position of the detection contact clamped in the rubber arc plate, which is convenient for adjusting the detection position of the detection contact in the narrow space of the electrical cabinet without moving the hand position.

[0008] Preferably, the outer surface of the rotating frame is fixedly connected with a dial piece, the outer surface of the driving rod is fixedly sleeved with a gear, and the outer surface of the gear is meshingly connected with the outer surface of the rotating frame.

[0010] Preferably, one end of the rubber arc plate is provided with a rubber tooth sleeve, and the outer surface of a rubber tooth plate arranged at the end of the rubber arc plate away from the rubber tooth sleeve is engaged with the inner surface of the rubber tooth sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The leakage detection equipment for the electrical cabinet, by placing the detection contact in the rubber arc plate, and through the cooperation of the rubber tooth plate and the rubber tooth sleeve, the fixation and protection of the contact are realized, the operator only needs to hold the insulating sleeve or the leakage detector without directly holding the detection contact to contact the electrical cabinet, the risk of leakage caused by the accidental contact of the hand with the electrical cabinet is effectively avoided, and the safety in the operation process is greatly improved.

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] See also Figs. 1-3 A leakage detection device for an electrical cabinet includes a leakage detector 1, a wire 2 electrically connected to the leakage detector 1, a detection contact 3 provided at one end of the wire 2 away from the leakage detector 1, an insulating rod 4 fixedly connected to the outer surface of the leakage detector 1, an insulating sleeve 5 fixedly provided on the outer surface of the insulating rod 4, a fixing bracket 6 fixedly provided on the outer surface of the insulating rod 4, and an inner surface of the fixing bracket 6 rotatably connected to a driving rod 7 via a shifting mechanism;

[0020] The driving rod 7 is provided with a movable clamping mechanism for clamping the detection contact 3 .

[0021] Through the above technical solution, during the use of the device, the detection contact 3 can be stably clamped by the movable clamping mechanism. It is only necessary to hold the leakage detector 1, contact the detection contact 3 with the corresponding position of the electrical cabinet, and use the wire 2 to electrically connect the leakage detector 1 and the detection contact 3. The measured leakage can be displayed in the form of data on the display screen of the leakage detector 1.

[0022] Specifically, the shifting mechanism includes a damping shaft 9 provided on the insulating rod 4 , and the outer surface of the damping shaft 9 is rotatably connected to a rotating bracket 10 .

[0023] Through the above technical solution, the damping shaft 9 has a damping characteristic. When the rotating frame 10 is subjected to a large force such as a toggle, the rotating frame 10 will rotate along the damping shaft 9. Otherwise, when no additional force is applied to the rotating frame 10, the rotating frame 10 can remain relatively stable.

[0024] Specifically, a paddle 11 is fixedly connected to the outer surface of the rotating frame 10 , a gear 12 is fixedly sleeved on the outer surface of the driving rod 7 , and the outer surface of the gear 12 is meshed with the outer surface of the rotating frame 10 .

[0025] Through the above technical solution, a section of teeth is provided on the rotating frame 10, and the teeth are used to cooperate with the gear 12, thereby driving the gear 12 to rotate to a certain extent.

[0026] Specifically, the movable clamping mechanism includes an arc piece 8 provided on the driving rod 7 at one end away from the leakage detector 1 , and a rubber arc plate 13 is provided on the end of the arc piece 8 away from the driving rod 7 .

[0027] Through the technical scheme, the arc piece 8 at the end of the drive rod 7 rotates during the rotation of the drive rod 7, and the position of the rubber arc plate 13 at the other end of the arc piece 8 can be adjusted.

[0028] Specifically, one end of the rubber arc plate 13 is provided with a rubber tooth sleeve 14, and the other end of the rubber arc plate 13 away from the rubber tooth sleeve 14 is provided with a rubber tooth plate 15, and the outer surface of the rubber tooth plate 15 is in meshing connection with the inner surface of the rubber tooth sleeve 14.

[0029] Through the technical scheme, the rubber tooth plate 15 gradually penetrates into the rubber tooth sleeve 14, which causes the rubber arc plate 13 to gradually shrink, thereby clamping the detection contact 3.

[0030] Working principle: During use, the detection contact 3 only needs to be in contact with the corresponding position of the electrical cabinet, and the electrical connection between the leakage detector 1 and the detection contact 3 is cooperated with the wire 2, so that whether there is leakage can be displayed on the display screen of the leakage detector 1 in the form of data. In order to avoid the hand from accidentally touching the electrical cabinet when the detection contact 3 is directly held in contact with the electrical cabinet, thereby causing the leakage hidden danger, at this time, the detection contact 3 can be placed in the rubber arc plate 13, and the rubber tooth plate 15 is gradually inserted into the rubber tooth sleeve 14, during which the rubber arc plate 13 will gradually shrink until the detection contact 3 is wrapped, and then only one hand holds the insulating sleeve 5 and the other hand controls the leakage detector 1, without the need to hold the detection contact 3 in contact with the electrical cabinet for detection, which effectively reduces the safety hidden danger. When the leakage detection is performed in the relatively small space inside the electrical cabinet, the insulating sleeve 5 can be held, and the leakage detector 1 and the detection contact 3 are in the appropriate position for control through the insulating rod 4, during which if the leakage detection is performed at different positions in the electrical cabinet, the hand does not need to be moved, and only the finger needs to be used to push the push piece 11 to apply force to the rotating frame 10, so that the rotating frame 10 rotates along the damping shaft 9, during which the rotating frame 10 drives the gear 12 at the gear teeth to rotate, so that the gear 12 rotates while driving the drive rod 7 to rotate synchronously, so that the arc piece 8 performs circular motion with the end in contact with the drive rod 7 as the center, and the detection contact 3 in the rubber arc plate 13 at the other end is changed in position, so that in the small space, the hand can be used to perform leakage detection at different positions in the electrical cabinet without moving the hand.

[0031] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
