Description

Technical Field

[0001] The utility model relates to the technical field of leakage fault detection devices, in particular to a leakage fault detection device for electric power facilities. Background Art

[0002] Leakage faults are common safety hazards in power systems. They not only lead to energy waste, but may also cause serious accidents such as fires and electric shocks, posing a threat to people's lives and property. Therefore, it is crucial to detect leakage faults accurately and promptly. Leakage fault detection devices need to have the characteristics of high sensitivity, fast response, and strong anti-interference ability.

[0036] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0037] like Figures 1 to 4 As shown, an embodiment of the utility model provides a leakage fault detection device for electric power facilities, comprising:

[0038] Instrument 1;

[0039] Button 2, fixedly connected to the surface of the instrument 1;

[0040] A detection sensor 3 is fixedly connected to the upper surface of the instrument 1;

[0041] A protective device 4 is provided on the surface of the instrument 1 to protect the instrument 1 from being damaged;

[0042] The accidental touch prevention device 5 is arranged on the surface of the instrument 1 to prevent the button 2 from being accidentally touched.

[0043] By providing the protection device 4 , the instrument 1 is not easily damaged; by providing the anti-mis-touch device 5 , the accuracy of using the button 2 is improved.

[0044] like Figure 1 to Figure 2 As shown, the protective device 4 includes a disc 405, which is fixedly connected to the lower surface of the instrument 1, and the arc surface of the disc 405 is fixedly connected to two fixed columns 406. The arc surface of the disc 405 is sleeved with a second circular shell 407, and the lower surface of the second circular shell 407 is fixedly connected to a rotating column 401, and the upper surface of the rotating column 401 is rotatably connected to the first circular shell 403, and the second circular shell 407 is located inside the first circular shell 403. The inner wall of the first circular shell 403 is provided with a threaded groove 404, and the arc surface of the second circular shell 407 is provided with a Z-shaped groove 408, and the fixed column 406 and the Z-shaped groove 408 slide through, and the fixed column 406 and the threaded groove 404 are slidably connected. By rotating the rotating column 401, the second circular shell 407 is driven to rotate. At this time, the fixed column 406 spirally rises along the Z-shaped groove 408 and the threaded groove 404, and drives the instrument 1 on the disc 405 to extend out of the second circular shell 407, so that the staff can use the instrument 1 conveniently. When the fixed column 406 rises to the highest point, it enters the uppermost horizontal groove of the Z-shaped groove 408, thereby preventing the disc 405 from falling naturally. When the instrument 1 finishes working, the rotating column 401 is rotated in the opposite direction. At this time, the instrument 1 enters the second circular shell 407, thereby improving the protection effect of the instrument 1.

[0045] like Figure 1 As shown, the arc surface of the first round shell 403 is fixedly connected with a plurality of rubber strips 402. When the staff uses the instrument 1, the existence of the rubber strips 402 increases the friction between the palm and the first round shell 403, making it easier for the staff to hold the instrument 1.

[0046] like Figures 1 to 3As shown, the inner wall of the second round shell 407 is provided with two square grooves 409, and the inner wall of the square groove 409 is rotatably connected with a rotating rod 411, and the arc surface of the rotating rod 411 is fixedly connected with a shielding plate 410, and the side of the shielding plate 410 and the square groove 409 close to each other is fixedly connected with a first spring 412. When the instrument 1 is extended, it contacts the shielding plate 410, and at this time, the two shielding plates 410 are pushed, and tilt upward and open under the action of the rotating rod 411, so as to facilitate the extension of the instrument 1, and the first spring 412 is pulled when the shielding plate 410 is opened and will be stretched. When the instrument 1 is retracted, the shielding plate 410 loses the push of the instrument 1, and at this time, the shielding plate 410 will be reset under the action of the pulling force of the first spring 412, so as to close the upper part of the second round shell 407, thereby improving the protection effect of the instrument 1.

[0047] like Figures 2 to 3 As shown, a rubber block 413 is fixedly connected to the lower surface of the shielding plate 410. When the shielding plate 410 is pushed by the instrument 1, the rubber block 413 first contacts the detection sensor 3 on the instrument 1. At this time, the setting of the rubber block 413 can effectively reduce the problem of collision between the detection sensor 3 and the shielding plate 410, thereby increasing the service life of the induction detector.

[0048] In the embodiment of the utility model (working principle), when the instrument 1 is working, the rotating column 401 is rotated so that the disk 405 drives the fixed column 406 to perform threaded movement in the threaded groove 404, and then the shielding plate 410 is pushed open, so that the instrument 1 can perform leakage fault detection conveniently. When the detection is completed, the rotating column 401 is rotated in the reverse direction to retract the instrument 1 into the second circular shell 407, thereby protecting the instrument 1 and reducing the possibility of damage to the instrument 1 caused by collision when being carried.

[0049] like Figure 1 and Figure 4 As shown, the anti-mis-touch device 5 includes two fixed blocks 51, which are fixedly connected to the upper surface of the instrument 1, and the side wall of the fixed block 51 is provided with a concave groove 52, and the concave groove 52 of the side wall of the fixed block 51 is slidably connected with a sliding block 53, and the side of the two sliding blocks 53 close to each other is fixedly connected with a trapezoidal block 55. The sliding block 53 drives the trapezoidal block 55 to slide in the fixed block 51, which is convenient for controlling the moving direction of the trapezoidal block 55. At this time, the trapezoidal block 55 presses the button 2, so as to facilitate the manipulation of the button 2 and reduce the situation where the button 2 is accidentally touched.

[0050] like Figure 1 and Figure 4 As shown, two fixing rods 57 are fixedly connected to the surface of the trapezoidal block 55, and a handle 56 is fixedly connected to one end of the fixing rod 57. The fixing rod 57 is manipulated to facilitate the fixing rod 57 to drive the trapezoidal block 55 to work.

[0051] like Figure 1 and Figure 4 As shown, the sliding block 53 and the concave groove 52 are fixedly connected to a second spring 54 on one side thereof close to each other. When the sliding block 53 drives the trapezoidal block 55 to press the button 2, the second spring 54 is stretched under the action of the sliding block 53. When the sliding block 53 is released, the tension of the second spring 54 drives the trapezoidal block 55 to reset.

[0052] In the embodiment of the utility model, by setting up an anti-accidental collision device, when it is necessary to operate the button 2 on the instrument 1, the handle 56 is pushed to drive the trapezoidal block 55 on the fixed rod 57 to slide toward the button 2, and the handle 56 is released. Under the action of the pulling force of the second spring 54, the trapezoidal block 55 will be reset. The setting of the fixed block 51 avoids the button 2 from being directly squeezed by external force.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
