Description

Technical Field

[0001] This invention relates to the field of power detection technology, and in particular to a substation fault detection device. Background Technology

[0002] As an important component of the power system for collecting and distributing electrical energy, a substation may cause regional power outages if it malfunctions. When maintenance personnel cannot quickly locate the fault point, they usually need to use fault detection devices to locate the fault point. However, when performing fault detection on the wires on the utility poles in the substation, it is necessary to manually climb the utility poles to perform wire detection through the fault detection devices.

[0003] When using the existing fault detection device, the first and second side plates need to be rotated out from the bottom of the fault detection box. Then, the screw on the first side plate is rotated to engage with the rotating plate on the second side plate, and the connection is fixed by tightening the nut on the screw. Finally, the threaded rods on the first and second side plates are rotated to move the corresponding clamping plates to hold the utility pole. Since the clamping plates in the above device have no structural constraints, they may rotate with the threaded rods, so manual restraint is required. The fixing steps are cumbersome, resulting in low fault detection efficiency. Summary of the Invention

[0037] This invention provides a substation fault detection device to solve the technical problem that existing fault detection devices have cumbersome procedures when fixed to utility poles, resulting in low fault detection efficiency.

[0038] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] Please see Figures 1 to 4 An embodiment of the present invention provides a substation fault detection device, comprising: a fault detection box 11, a first clamping plate 12, a second clamping plate 13, a snap-fit ​​shell 25, a snap-fit ​​rod 26, and a threaded rod 27;

[0040] The bottom of the fault detection box 11 is provided with a slide groove 21, and a fixing mechanism is slidably provided in the slide groove 21. The first ends of the first clamping plate 12 and the second clamping plate 13 are both pivotally connected to the fixing mechanism.

[0041] The first clamping plate 12 and the second clamping plate 13 face each other to form a clamping area, and the first ends of the first clamping plate 12 and the second clamping plate 13 are both connected to the fixing mechanism through the elastic element 291.

[0042] The snap-fit ​​housing 25 is pivotally connected to the second end of the second clamping plate 13, the first end of the snap-fit ​​rod 26 is embedded in the first end of the snap-fit ​​housing 25, and the threaded rod 27 passes through the second end of the snap-fit ​​housing 25 and is connected to the first end of the snap-fit ​​rod 26.

[0043] The second end of the latching rod 26 is provided with a stop 28, which is used to abut against the second end of the first clamping plate 12.

[0044] In this embodiment, a groove 21 is provided at the bottom of the fault detection box 11. A fixing mechanism is slidably arranged in the groove 21. The first ends of the first clamping plate 12 and the second clamping plate 13 are both pivotally connected to the fixing mechanism. Therefore, the fixing mechanism can drive the first clamping plate 12 and the second clamping plate 13 to extend or retract from the bottom of the fault detection box 11 along the groove 21. At least two sets of elastic elements 291 are provided. The first ends of the first clamping plate 12 and the first ends of the second clamping plate 13 are connected to the fixing mechanism through a set of elastic elements 291. On the one hand, this can limit the excessive opening and random rotation between the first clamping plate 12 and the second clamping plate 13. On the other hand, based on the elastic characteristics, it can adapt to different diameters of utility poles and provide clamping force when the second ends of the first clamping plate 12 and the second clamping plate 13 are inserted into the clamping area formed by the two facing each other. In specific implementation, the elastic element 291 can be a spring or a torsion spring. In order to achieve The fault detection box 11 is clamped and fixed to the utility pole. By rotating the buckle shell 25, the top of the buckle rod 26 contacts the bottom of the second end of the first clamping plate 12, and then the threaded rod 27 is rotated. The buckle rod 26 is restricted from rotating because it is embedded in the buckle shell 25. When the threaded rod 27 rotates, it will drive the buckle rod 26 to retract into the buckle shell 25 until the stop block 28 on the buckle rod 26 contacts the side of the second end of the first clamping plate 12, and continues to push the second ends of the first clamping plate 12 and the second clamping plate 13 to close. Based on the above scheme, the position of the first clamping plate 12 and the second clamping plate 13 can be smoothly changed through the fixing mechanism and the sliding groove 21. The first clamping plate 12 and the second clamping plate 13 are closed and clamped by the cooperation of the buckle shell 25, the buckle rod 26, the threaded rod 27 and the stop block 28, so that the first clamping plate and the second clamping plate clamp and fix the utility pole. Compared with the existing device, it is simpler and more convenient to operate and more efficient to use.

[0045] It should be noted that, in specific implementation, the fault detection box 11 is equipped with a testing instrument inside, and the fault detection box 11 is equipped with a test port that connects to the testing instrument. Through the test port, it can be connected to the wire to be tested on the utility pole. After ensuring a firm connection, the test parameters such as the test voltage and test frequency of the testing instrument can be set according to the basic parameters such as the type and length of the wire to be tested. Pressing the test button of the testing instrument inside the fault detection box 11 will start the wire fault detection. The testing instrument will automatically scan the wire and display the test results. Based on the test results, the location and type of substation faults can be analyzed and repaired.

[0046] In a more specific embodiment, see Figure 2 and Figure 3 The fixing mechanism includes a slider 22 and a pusher connected in sequence;

[0047] The slider 22 is slidably disposed in the groove 21, and the slider 22 is provided with ball bearings 221;

[0048] The first ends of the first clamping plate 12 and the second clamping plate 13 are both pivotally connected to the pushing member, and both are connected to the pushing member through the elastic member 291.

[0049] In one specific embodiment of this example, see [reference needed]. Figure 5 The pushing component includes a housing 23 and a pull plate 36;

[0050] The first end of the first clamping plate 12 and the second clamping plate 13 is pivotally connected to the housing 23 and connected to the elastic member 291. The first end of the housing 23 is connected to the slider 22.

[0051] A limiting post 37 is provided inside the housing 23. The limiting post 37 is fitted with a sliding plate 32 and a return spring 34. The return spring 34 abuts between the first end of the sliding plate 32 and the second end of the housing 23.

[0052] The pull plate 36 is provided with a pull rod 35, and the second end of the pull rod 35 passes through the housing 23 and is connected to the first end of the slide plate 32;

[0053] The second end of the slide plate 32 is provided with a plug rod 33, and the bottom of the fault detection box 11 is provided with a slot 31. The first end of the plug rod 33 passes through the housing 23 and is inserted into the slot 31.

[0054] In a more specific implementation, see Figure 2 and Figure 5 There are two pull rods 35, which are symmetrically distributed with respect to the limiting post 37;

[0055] There are two insertion rods 33, and the positions of the insertion rods 33 and the pull rods 35 correspond to those of the pull rods 35.

[0056] There are two slots 31, both of which are located close to the second end of the slide groove 21 away from the first clamping plate 12.

[0057] In this embodiment, by pulling the pusher to move the slider 22 connected to it along the area of ​​the slide groove 21, the first clamping plate 12 and the second clamping plate 13 are moved at the bottom of the fault detection box 11. The slider is also provided with ball bearings 221 to reduce friction and make the sliding smoother.

[0058] To ensure that the first clamping plate 12 and the second clamping plate 13 can be securely stored at the bottom of the fault detection box 11, in one implementation, the pushing component includes a housing 23 and a pull plate 36: the outer wall of the housing 23 is provided with two sets of limiting members, and the limiting members are provided with clamping plate rotation shafts. The first end of the first clamping plate 12 or the second clamping plate 13 is sleeved on the clamping plate rotation shaft, thereby realizing the pivot connection between the first clamping plate 12 and the second clamping plate 13 and the housing 23; the housing 23 is provided with a limiting post 37 connecting the first end and the second end of the housing 23. A sliding plate 32 and a return spring 34 are fitted onto the limiting post 37. The return spring 34 abuts between the first end of the sliding plate 32 and the second end of the housing 23. A pull plate 36 is externally mounted on the housing 23. A pull rod 35 on the pull plate 36 passes through the second end of the housing 23 and connects to the first end of the sliding plate 32. A plug rod 33 is provided at the second end of the sliding plate 32. By pushing and pulling the pull plate 36, the sliding plate 32 can be moved up and down along the limiting post 37. During this process, the plug rod 33 at the second end of the sliding plate 32 connects with the fault detection box. The slot 31 at the bottom of the fault detection box 11 is in an inserted or disengaged state, and the return spring 34 is in an extended or compressed state. In specific implementation, if it is necessary to release the fixation after the test is completed, rotate the threaded rod 27 to make the latching rod 26 extend out of the inside of the latching shell 25, then rotate the latching shell 25 to disengage the first clamping plate 12 and the second clamping plate 13 from both sides of the utility pole, and then pull the shell 23 to move the first clamping plate 12 and the second clamping plate 13 back to the bottom of the fault detection box 11 until the slot 31 and the latching rod 33 are aligned. When the return spring 34 rebounds, it pushes the slide plate 32 towards the bottom of the fault detection box 11, so that the insertion rod 33 can be inserted into the slot 31 to fix the position of the housing 23, thereby achieving the stability of the storage of the first clamping plate 12 and the second clamping plate 13, making it less likely to slide out. To release the fixation effect, simply pull the pull plate 36 to drive the pull rod 35 to move the slide plate 32 away from the bottom of the fault detection box 11, and the insertion rod 33 can be pulled out from the slot 31. The operation is simple and effective.

[0059] In a preferred embodiment of this structure, two pull rods 35 and two slots 31 are provided for both the pull rod 35 and the insertion rod 33. The two pull rods 35 are symmetrically distributed relative to the limiting post 37, and the positions of the pull rods 35 and the insertion rod 33 correspond to each other, resulting in a uniform force distribution. This provides a more accurate positioning effect when the insertion rod 33 is inserted into the slot 31. Furthermore, two slots 31 can be provided. In this case, both slots 31 are located close to the second end of the slide groove 21 away from the first clamping plate 12 or the second clamping plate 13, which can help to securely accommodate the first clamping plate 12 and the second clamping plate 13. The two clamping plates 13, or the slots 31, can be provided with four slots. Each pair of slots 31 are distributed close to both sides of the slide groove 21. It can be understood that two of the slots 31 are distributed close to the second end of the slide groove 21 near the first clamping plate 12 or the second clamping plate 13, and the other two slots 31 are distributed close to the second end of the slide groove 21 away from the first clamping plate 12 or the second clamping plate 13. The arrangement of the four slots 31 can further stabilize and limit the position when the first clamping plate 12 and the second clamping plate 13 extend and clamp the utility pole.

[0060] In a more specific embodiment, see [link to relevant documentation] Figure 2 The bottom of the fault detection box 11 is provided with two sets of upright plates 293, and the first clamping plate 12 and the second clamping plate 13 both abut against one set of upright plates 293.

[0061] In this embodiment, two sets of upright plates 293 are arranged facing each other at the bottom of the fault detection box 11. The first clamping plate 12 and the second clamping plate 13 abut against one set of upright plates 293. When the first clamping plate 12 and the second clamping plate 13 are still at the bottom of the fault detection box 11, they are squeezed by the two sets of upright plates 293. When the fixing mechanism drives them to move away from the limiting area of ​​the two sets of upright plates 293 facing each other, the first clamping plate 12 and the second clamping plate 13 are spontaneously pushed to unfold under the action of the elastic member 291. The arrangement of the two sets of upright plates 293 can restrict the first clamping plate 12 and the second clamping plate 13 from swinging arbitrarily.

[0062] In a more specific embodiment, see [link to relevant documentation] Figures 1 to 3 Both the first clamping plate 12 and the second clamping plate 13 are arc-shaped. In specific implementation, the first clamping plate 12 and the second clamping plate 13 can form various shapes for clamping, such as rectangular, L-shaped, V-shaped and arc-shaped, etc. Choosing to use an arc shape will better fit the shape of the utility pole and provide a larger contact area, thus helping to maintain a good fixing effect.

[0063] In a more specific embodiment, see [link to relevant documentation] Figure 3Both the first clamping plate 12 and the second clamping plate 13 have rubber pads 292 on their inner sidewalls in the clamping area. By providing rubber pads 292 on the inner sidewalls that contact the utility pole, it is possible to avoid scratching or abrading the surface of the utility pole, and to increase friction, thereby enhancing the connection stability between the first clamping plate 12 and the second clamping plate 13 and the utility pole.

[0064] In a more specific embodiment, see [link to relevant documentation] Figure 3 A stop block 281 is provided at the second end of the first clamping plate 12, which is used to abut against the stop block 28. When the stop block 28 on the latching rod 26 abuts against the second end of the first clamping plate 12, it can drive the first clamping plate 12 to move closer to the second clamping plate 13. By further providing the stop block 281, the stop block 28 can be prevented from shifting and disengaging from the second end of the first clamping plate 12, thereby ensuring the stable closure of the first clamping plate 12 and the second clamping plate 13.

[0065] In a more specific embodiment, see [link to relevant documentation] Figure 3 Two sets of connecting seats 24 are symmetrically arranged at the second end of the second clamping plate 13; the snap-fit ​​shell 25 is rotatably disposed between the two sets of connecting seats 24. The limiting of the two sets of connecting seats 24 helps to ensure that the snap-fit ​​shell 25 can be stably fixed, while allowing the snap-fit ​​shell 25 to have a certain degree of swing freedom on the fixed basis. In specific implementation, the snap-fit ​​shell 25 and the connecting seat 24 can be rotatably connected by a rotating shaft, such as the rotating shaft on the first set of connecting seats 24 passing through the snap-fit ​​shell 25 and connecting to the second set of connecting seats 24.

[0066] In a more specific embodiment, see [link to relevant documentation] Figure 2 and Figure 3 A knob 29 is provided on the outside of the threaded rod 27. The knob 29 provides a good gripping surface and allows for more precise adjustment of the threaded rod 27.

[0067] In a more specific embodiment, see [link to relevant documentation] Figure 2 and Figure 3 Both the snap-fit ​​housing 25 and the snap-fit ​​rod 26 are rectangular. In specific implementation, while ensuring that the snap-fit ​​housing 25 can accommodate the threaded rod 27, it can also limit the snap-fit ​​housing 25's position on the snap-fit ​​rod 26. The snap-fit ​​housing 25 and the snap-fit ​​rod 26 can adopt matching cylindrical, rectangular, or polygonal shapes, etc., without any specific restrictions.

[0068] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
