Description

Technical Field

[0001] The present invention relates to the technical field of electric fault detection, and in particular to an automatic detection method and system for electric equipment. Background Art

[0002] Intelligent power distribution facilities are a highly intelligent power distribution network formed by integrating modern information technology, automation technology and communication technology on the basis of traditional power distribution systems. Its core is to achieve real-time monitoring and intelligent management of power flow, equipment status and user power consumption behavior through advanced sensors, smart meters and automation equipment, thereby improving the reliability and flexibility of power supply.

[0003] In actual use, the existing electrical fault detection device for intelligent power distribution facilities has the following problems: since the lines are neatly arranged and fit against the inner wall of the facility, when using a clamp-type detection device to detect electrical faults, the clamp-type detection clamp in front of the detection device needs to clamp the wire harness into the detection clamp. However, since the detection clamp has a detection function, it is not convenient to clamp the wire harness that is closely attached to the inner wall of the facility. If it is done manually, it is too dangerous. Using a screwdriver to pry open the wire harness and then using the clamp-type detection device for detection is inefficient.

[0004] Based on this, the present invention discloses an automatic detection method and system for electrical equipment. Summary of the invention

[0005] In order to solve the problems raised in the background technology, the present invention provides an automatic detection method for electrical equipment, which is used to detect circuit faults in intelligent power distribution facilities, including an electrical fault detection device, a clamp-type detection clip is provided at the front end of the electrical fault detection device, which is used to detect line faults, and a pressing key for controlling the retraction and extension of the clamp-type detection clip is provided on one side of the electrical fault detection device; It also includes a wire box, an extrusion rod, a wire clamp, a rack, a limit rod and a slider. The specific steps for testing are as follows: S1, initial state, the clamp-type detection clamp is in the combined state, the prying clamp is in the open state, and the extrusion rod is pressed so that the slider is limited by the limit rod after accumulating force in the prying box; S2. Press the push button. During the pressing process, the clamp-type detection clamp gradually opens, and the push button drives the wire prying clamp to gradually merge through the rack, thereby clamping the wire harness that fits the inner wall of the facility; S3. When the wire clamp is completely combined, the pressing button drives the rack to trigger the limit rod, releases the limit rod from limiting the slider, and releases the pressing button; S4. After the slider is released from the limit, the slider with accumulated force drives the combined prying clamp to eject, thereby driving the wire harness clamped by the prying clamp to be pried up; S5. During the ejection of the slider, the wire prying clamp drives the wire harness to be pried up and the wire prying clamp gradually opens. After the pressing button is released, the clamp-type detection clamp begins to reset and merge until it circles the wire harness pried up by the wire prying clamp.

[0006] As a further improvement of the present technical solution, an ejection slot is provided in the wire pry box, the slider is slidably connected to the ejection slot, a second spring is provided in the ejection slot, one end of the second spring is fixedly connected to the slider, and the other end is fixedly connected to the inner wall of the ejection slot. In an initial state, the second spring lifts the slider to fit the inner wall of the ejection slot, and an extrusion rod is fixedly connected to the side of the slider away from the second spring, and the extrusion rod forms a pressing portion after passing through the ejection slot.

[0007] As a further improvement of the present technical solution, the slider is symmetrically fixedly connected with a first rotating rod and a second rotating rod, the first rotating rod is fixedly connected with a third gear and a first gear in sequence from bottom to top, the second rotating rod is fixedly connected with a second gear, the first gear and the second gear are meshed with each other, and the two clips of the wire clamp are symmetrically fixedly connected to the top ends of the first rotating rod and the second rotating rod respectively.

[0008] As a further improvement of the technical solution, the two clips of the wire prying clamp are L-shaped structures, and the lateral end of the top of the wire prying clamp is a sharp structure. A first spring is fixedly connected between the two clips of the wire prying clamp, so that the wire prying clamp always has a tendency to open.

[0009] Preferably, a slide groove is provided in the wire prying box, the rack is slidably connected in the slide groove, the rack is meshed with the third gear, one end of the rack located in the slide groove is fixedly connected to a push rod, an oblique groove is provided at the bottom of the push key, and one end of the rack located outside the slide groove is slidably connected to the oblique groove through a connecting rod.

[0010] As a further improvement of the technical solution, a receiving groove adapted to the opening angle of the wire prying clamp is provided at one end of the wire prying box adjacent to the clamp-type detection clamp, a limit rod is rotatably arranged in the receiving groove, a torsion spring is arranged on the limit rod, a movable groove is provided in the wire prying box on the side of the ejection groove away from the rack, and a limit groove and a notch connected to the ejection groove are provided on the side of the movable groove adjacent to the ejection groove.

[0011] Preferably, the top end of the limiting rod is a hook structure, and the top end of the hook structure is a smooth structure. The hook of the limiting rod passes through the limiting groove and is located in the ejection groove. The torsion spring always has a tendency to cause the hook of the limiting rod to be located in the ejection groove.

[0012] As a further improvement of the technical solution, when the slider is in a force storage state, the slider is located on the side of the limit rod's hook away from the extrusion rod and fits together, and the limit rod's hook limits the slider; and the top of the pry wire clamp exceeds the top of the clamp-type detection clamp.

[0013] Preferably, when the limiting rod limits the sliding block, when the rack slides in the sliding groove, the rack meshes with the third gear; When the rack drives the wire clamp through the third gear to complete the merging, the push rod passes through the notch and fits with the limiting rod.

[0014] The second object of the present invention is to provide a system for the electrical equipment automatic detection method: the wire prying box is arranged at the bottom of the electrical fault detection device, the clamp-type detection clamp is used in combination with the wire prying box, and after the wire prying clamp is ejected, the clamp-type detection clamp encircles the wiring harness to be detected.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this method for automatic detection of electrical equipment, by setting a hook structure and a torsion spring on the limit rod and a push rod on the rack, when the prying clamp is about to be merged, the push rod triggers the limit rod to release its limit on the slider, which is conducive to automatically releasing the limit on the slider after the prying clamp is merged, so that the slider can be ejected smoothly, driving the prying clamp and the wiring harness to be pried up together.

[0016] 2. In this method for automated detection of electrical equipment, a wire prying clamp is set to be ejected in an ejection slot and gradually opens during the ejection process, which can not only drive the wire harness to be pried up, but also avoid excessive prying that affects the connection of the wire harness. This is beneficial for effectively prying up the wire harness to be detected while protecting the wire harness, and is convenient for clamping and detection of the clamp-type detection clamp.

[0017] 3. In this method for automatic detection of electrical equipment, when it is necessary to detect the wiring harness close to the inner wall of the facility, first press the extrusion rod to store force on the slider, and then press the push button to drive the wire prying clamp to merge and clamp the wire harness. Without directly clamping the wire harness, first use the wire prying clamp to circle and pry up the wire harness, so as to facilitate the subsequent pliers-type detection clamp to merge and circle the wire harness, thereby improving the efficiency of electrical fault detection; secondly, a rack, a third gear, and a first gear and a second gear meshing therewith are provided. When the button is pressed, the rack slides and drives the third gear to rotate, thereby driving the two clips of the wire prying clamp to merge, so as to automatically drive the wire prying clamp to perform a merging operation while pressing the button.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The existing clamp-type detection device is not convenient for detecting the wire harness that is close to the inner wall of the facility, so that the clamp-type detection clamp cannot directly clamp the wire harness, resulting in low efficiency in electrical fault detection.

[0022] To this end, the present invention provides an automatic detection method for electrical equipment. Figure 1 As shown, it is used to detect circuit faults in intelligent power distribution facilities, including an electrical fault detection device 1, a clamp-type detection clip 2 is arranged at the front end of the electrical fault detection device 1 for detecting line faults, and a pressing key 3 for controlling the retraction and extension of the clamp-type detection clip 2 is arranged on one side of the electrical fault detection device 1.

[0023] For details, see Figure 4 , Figure 5 and Fig. 9 As shown, it also includes a wire prying box 5, a squeezing rod 6, a wire prying clamp 7, a rack 8, a limiting rod 11 and a slider 13, wherein an ejection slot 18 is provided in the wire prying box 5, the slider 13 is slidably connected to the ejection slot 18, a second spring 23 is provided in the ejection slot 18, one end of the second spring 23 is fixedly connected to the slider 13, and the other end is fixedly connected to the inner wall of the ejection slot 18. In the initial state, the second spring 23 lifts the slider 13 to fit the inner wall of the ejection slot 18, and the side of the slider 13 away from the second spring 23 is fixedly connected with the squeezing rod 6, and the squeezing rod 6 forms a pressing portion after passing through the ejection slot 18; See also Fig. 9 As shown, the slider 13 is symmetrically fixedly connected with a first rotating rod 17 and a second rotating rod 25, the first rotating rod 17 is fixedly connected with a third gear 16 and a first gear 14 in sequence from bottom to top, the second rotating rod 25 is fixedly connected with a second gear 15, the first gear 14 and the second gear 15 are meshed, and the two clips of the wire prying clamp 7 are symmetrically fixedly connected to the top ends of the first rotating rod 17 and the second rotating rod 25, respectively, wherein the two clips of the wire prying clamp 7 are L-shaped structures, and the lateral ends of the top ends of the wire prying clamp 7 are sharp structures, and a first spring 20 is fixedly connected between the two clips of the wire prying clamp 7, so that the wire prying clamp 7 always has a tendency to open, so that it is convenient to use the clamp-type detection clamp 2 again later, and at the same time, the pressing key 3 is pressed to drive the clamp-type detection clamp 2 to open and drive the wire prying clamp 7 to merge, that is, before using the clamp-type detection clamp 2, the wire harness is firstly encircled and pried up by merging the wire prying clamp 7, so that it is convenient for the subsequent merging of the clamp-type detection clamp 2 to encircle the wire harness.

[0024] For further information, see Figure 8 As shown, a slide groove 24 is provided in the pry box 5, and the rack 8 is slidably connected in the slide groove 24. The rack 8 is meshed with the third gear 16. One end of the rack 8 located in the slide groove 24 is fixedly connected to the push rod 19. An inclined groove 4 is provided at the bottom of the push button 3. One end of the rack 8 located outside the slide groove 24 is slidably connected in the inclined groove 4 through a connecting rod. Figure 1 It can also be seen that the pressing of the push button 3 will drive the rack 8 to slide in the slide groove 24 through the connecting rod, and the inclined groove 4 is provided to meet the pressing movement of the push button 3 to drive the rack 8 to slide linearly in the slide groove 24, and the rack 8 and the connecting rod are also rotationally connected; For details, see Figure 4 and Figure 5As shown, a receiving groove 9 adapted to the opening angle of the wire prying clamp 7 is provided at one end of the wire prying box 5 adjacent to the clamp-type detection clamp 2, a limit rod 11 is rotatably arranged in the receiving groove 9, a torsion spring 12 is arranged on the limit rod 11, a movable groove 10 is provided in the wire prying box 5 on the side of the ejection groove 18 away from the rack 8, and a limit groove 21 and a notch 22 connected to the ejection groove 18 are provided on the side of the movable groove 10 adjacent to the ejection groove 18.

[0025] It is worth mentioning that Figure 5 It can be seen that the top of the limit rod 11 is a hook structure, and the top of the hook structure is a smooth structure. The hook of the limit rod 11 passes through the limit groove 21 and is located in the ejection groove 18. The torsion spring 12 always has a tendency to cause the hook of the limit rod 11 to be located in the ejection groove 18. Figure 6 It can be clearly seen that the hook of the limiting rod 11 penetrates deep into the ejection groove 18 through the limiting groove 21, so that when the slider 13 is pressed by the extrusion rod 6 to slide in the ejection groove 18, the slider 13 first hits the smooth part of the hook of the limiting rod 11, so that the limiting rod 11 is tilted, so that the slider 13 can pass through, and then when the slider 13 reaches the other end of the ejection groove 18, the hook of the limiting rod 11 just hooks the side of the slider 13 away from the second spring 23, so that the slider 13 will not be ejected by the second spring 23, that is, the slider 13 is limited at this time. This position is exactly the position where the rack 8 and the third gear 16 described below can engage.

[0026] For details, see Figure 8 As shown, when the slider 13 is in the power storage state, the slider 13 is located at the side of the hook of the limiting rod 11 away from the extrusion rod 6 and fits each other, and the hook of the limiting rod 11 limits the slider 13; and the top of the prying wire clamp 7 exceeds the top of the clamp-type detection clamp 2, so that the prying wire clamp 7 can first clamp and circle the wire harness, and then pry it up, and then the clamp-type detection clamp 2 can circle the pried-up wire harness; When the limiting rod 11 limits the slider 13, the rack 8 slides in the slide groove 24, and the rack 8 meshes with the third gear 16; When the rack 8 drives the wire clamp 7 through the third gear 16 to complete the merging, the push rod 19 passes through the notch 22 and fits with the limit rod 11. Figure 8It can be seen that when the wire clamp 7 is about to be merged, the push rod 19 has passed through the notch 22 and has been fitted with the limit rod 11. When the push button 3 is pressed further to drive the rack 8 to slide further along the slide groove 24, the push rod 19 will lift the limit rod 11, so that the hook of the limit rod 11 will be out of contact with the slider 13, that is, the hook of the limit rod 11 is retracted into the movable groove 10 through the limit groove 21, so that the limit rod 11 releases the limit on the slider 13, and the slider 13 will drive the wire clamp 7 to be ejected in the ejection groove 18 through the elastic force of the second spring 23; at this time, the wire clamp 7 is in a merged state, so the slider 13 drives the wire clamp 7 to be ejected and also drives the wire harness to be pried up, and In order to protect the wiring harness and meet the need of keeping the wire prying clamp 7 open all the time, when the slider 13 is ejected, the third gear 16 is disengaged from the gear rack 8, and the wire prying clamp 7 is gradually opened in the accommodating groove 9. The opening of the wire prying clamp 7 requires a certain process, and during this process, the wire prying clamp 7 is also ejected along the ejection groove 18, so the lateral end of the wire prying clamp 7 drives the wire harness to be pried up, and then the wire prying clamp 7 is opened to be separated from the wire harness, and no longer drives the wire harness to be pried up, which can not only achieve the prying effect on the fitted wire harness, but also protect the wire harness from being excessively pried up, and also prevent the wire prying clamp 7 from always being separated from the wire harness during the ejection of the slider 13, causing injuries to the staff due to the handheld electrical fault detection device 1.

[0027] In this way, when the button 3 is reset, the clamp-type detection clamp 2 encircles the wire harness, and the slider 13 is also reset, and the wire prying clamp 7 is restored to the initial opening angle and initial position. When the detection wire harness needs to be replaced, the above operation can be repeated.

[0028] For further information, see Figure 5 , Figure 6 and Figure 8 As shown, the specific detection steps are as follows: S1, initial state, the clamp-type detection clamp 2 is in the combined state, the prying clamp 7 is in the open state, and the squeezing rod 6 is pressed so that the slider 13 is limited by the limiting rod 11 after accumulating force in the prying box 5; S2. Press the pressing key 3. During the pressing process, the clamp-type detection clamp 2 gradually opens, and the pressing key 3 drives the wire prying clamp 7 to gradually merge through the rack 8, thereby clamping the wire harness that is attached to the inner wall of the facility; S3, when the wire clamp 7 is completely merged, the pressing key 3 drives the rack 8 to just trigger the limit rod 11, releases the limit of the slider 13 by the limit rod 11, and releases the pressing key 3; S4, after the slider 13 is released from the limit, the slider 13 with stored force drives the combined wire prying clamp 7 to eject, thereby driving the wire harness clamped by the wire prying clamp 7 to pry up, and obtaining a wire harness with a certain curvature; S5. During the ejection of the slider 13, the wire prying clamp 7 drives the wire harness to be pried up and the wire prying clamp 7 also gradually opens. After the pressing key 3 is released, the clamp-type detection clamp 2 starts to reset and merge until it circles the wire harness pried up by the wire prying clamp 7.

[0029] In summary, by first pressing the extrusion rod 6, the slider 13 squeezes the second spring 23 and is then limited by the limit rod 11, so that the slider 13 is in a force storage state, and then the rack 8 is driven to slide while pressing the pressing key 3. When the slider 13 is in the limited position, the rack 8 slides and meshes with the third gear 16, thereby driving the third gear 16 to rotate, and then the two clips of the prying clamp 7 are driven to merge through the first gear 14 and the second gear 15. Since the clips are thin and sharp, they can easily pass through the fitting between the wire harness and the inner wall and circle the wire harness. While pressing the pressing key 3, the clamp-type detection clamp 2 needs to be opened. Here, the pressing key 3 drives the clamp-type detection clamp 2 to open and close, and the specific detection structure in the clamp-type detection clamp 2 is the prior art, which will not be described in detail here. While pressing the key 3 to drive the clamp-type detection clamp 2 to open and close, it drives the prying clamp 7 to merge. When the prying clamp 7 completes the merger, , the lifting rod 19 triggers the release of the limit of the slider 13, so that the slider 13 drives the wire prying clamp 7 to be ejected in the ejection groove 18, and at the same time, the encircled wire harness is pried up, and the random clamp-type detection clamp 2 can encircle the wire harness to be detected for detection, and the wire prying clamp 7 will gradually reset and open due to the existence of the first spring 20 during the ejection process, preparing for the next detection, and the lateral end of the wire prying clamp 7 has a certain length, so the wire prying clamp 7 can drive the wire harness to be pried up during the ejection process, and at the same time, it can also avoid affecting the connection of the wire harness due to excessive ejection, because the wire prying clamp 7 has a process of ejecting and opening at the same time, and the lateral end of the wire prying clamp 7 is in contact with the wire harness during the opening process, so it can drive the wire harness to be pried up; thereby effectively solving the problem that the existing clamp-type detection device is not convenient for detecting the wire harness that is close to the inner wall of the facility, so that the clamp-type detection clamp cannot directly clamp the wire harness, resulting in low efficiency in electrical fault detection.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
