Description

Technical Field

[0001] This utility model relates to the field of arc detector technology, specifically an arc detection device. Background Technology

[0002] Arc detection equipment is a device used to detect and prevent electrical fires and electrical equipment failures. For example, arc detectors are common sensing devices in industrial automation and power systems, used to monitor arc discharge phenomena that may occur during the operation of electrical equipment. Arc discharge is a common electrical fault that can cause serious damage to equipment and even cause safety accidents such as fires. Therefore, installing and stably fixing arc detectors is of great significance for timely detection and prevention of arc discharge faults.

[0003] However, due to the unstable fixing method of the arc probe, it is easy for the probe position to shift when subjected to external impact, which affects the monitoring accuracy. In addition, the mounting plates of different thicknesses and sizes have poor adaptability to the equipment, which limits its application range. Therefore, an arc detection device is needed to solve the existing shortcomings. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an arcing monitoring device.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an arc detection device, comprising a mounting plate, a support cylinder, and an arc probe. The support cylinder penetrates the mounting plate and is movably connected to the mounting plate. Two sets of symmetrical limiting rings are movably connected to the outer side of the support cylinder, and the mounting plate is located on the opposite side of the limiting rings. An adjustment mechanism is provided inside the support cylinder and is movably connected to the limiting rings. Adjusting rings are fixedly connected to both ends of the adjustment mechanism. A fixing mechanism is movably connected to one side of the adjusting ring. The arc probe penetrates the support cylinder, and the fixing mechanism is movably connected to the outer side of the arc probe.

[0008] The aforementioned adjustment mechanism includes a moving ring and an adjustment cylinder. The moving rings are symmetrically arranged and are movably connected to the inside of the support cylinder. A set of symmetrical threads is provided on the outer side of the adjustment cylinder. The adjustment cylinder passes through the moving rings and is threadedly connected to the moving rings. The arc light probe passes through the adjustment cylinder and is movably connected to the adjustment cylinder.

[0009] As described above, the adjusting cylinder is movably connected to the inside of the support cylinder, and both ends of the adjusting cylinder extend to the outside of the support cylinder. The two ends of the adjusting cylinder are respectively fixedly connected to the adjusting ring.

[0010] As described above, several guide blocks are fixedly connected to the outer side of the movable ring, and the guide blocks are distributed in a circular array. Multiple sets of symmetrical guide grooves are opened on the outer side of the support cylinder, and the guide blocks are movably connected to the guide grooves respectively.

[0011] As described above, the opposite sides of the limiting ring are engaged with each other, and each opposite side of the limiting ring is fixedly connected with a positioning post. The outer side of the guide block is provided with a positioning hole, and the positioning post is adapted to the positioning hole.

[0012] The aforementioned fixing mechanism includes a fixing post, a return spring, a push ring, and a control ring. The push ring is fixedly connected to one side of the control ring. The fixing post and the return spring are both arranged in a circular array. The fixing post is movably connected to the inside of the adjusting ring, and one end of the fixing post is in contact with the outside of the arc probe. The bottom end of the return spring is fixedly connected to the top end of the fixing post, and the top end of the return spring is fixedly connected to the inside of the adjusting ring.

[0013] As described above, the outer side of the push ring is threaded, and the push ring is rotatably connected to the inside of the adjusting ring through the thread. The outer side of the fixed column is provided with a control groove, and the inner side of the control groove is constructed with an inclined surface. The end of the push ring abuts against the inclined surface of the control groove.

[0014] Beneficial effects:

[0015] Compared with existing technologies, this arcing monitoring device has the following advantages:

[0016] I. This utility model, through its adjustable mechanism, rotates the adjusting ring, causing the adjusting cylinder to rotate inside the support cylinder. Since the moving ring is threadedly connected to the adjusting cylinder, and the guide block slides inside the guide groove, the moving rings are driven to move closer to each other, and the guide blocks move closer to each other along the guide groove, causing the limiting rings to move closer to each other until the limiting rings are tightly fitted to the surface of the mounting plate. This allows the support cylinder to be installed at the opening of the mounting plate, making it suitable for mounting plates of different thicknesses and opening sizes. Installation and disassembly are also relatively simple.

[0017] II. This utility model uses a fixed mechanism to insert the arc light probe through the adjusting cylinder. Then, by rotating the control ring, the push ring rotates forward inside the adjusting ring, causing the push ring to abut against the inclined surface of the control groove. This causes the fixed post to move outward toward the outside of the arc light probe until the end of the fixed post is in close contact with the outer surface of the arc light probe. At this time, the return spring is stretched and elongated, thereby fixing the arc light probe to the mounting plate. This helps to improve the stability of the arc light probe installation and reduce the positional displacement of the arc light probe caused by external impact.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, this utility model provides a technical solution: an arc detection device, including a mounting plate 1, a support cylinder 2, and an arc probe 3. The support cylinder 2 penetrates the mounting plate 1 and is movably connected to the mounting plate 1. Two sets of symmetrical limiting rings 4 are movably connected to the outer side of the support cylinder 2, and the mounting plate 1 is located on the opposite side of the limiting rings 4. An adjustment mechanism 5 is provided inside the support cylinder 2 and is movably connected to the limiting rings 4. Adjustment rings 6 are fixedly connected to both ends of the adjustment mechanism 5. A fixing mechanism 7 is movably connected to one side of the adjustment ring 6. The arc probe 3 penetrates the support cylinder 2, and the fixing mechanism 7 is movably connected to the outer side of the arc probe 3.

[0027] First, the support cylinder 2 is inserted through the opening of the mounting plate 1. Then, the positioning pin 10 on the inner side of the limiting ring 4 engages with the positioning hole 11 on the outer side of the moving ring 501, thereby fixing the limiting ring 4 to the outer side of the moving ring 501. The limiting ring 4 is located on both sides of the mounting plate 1. Then, the adjusting ring 6 is rotated, causing the adjusting cylinder 502 to rotate inside the support cylinder 2. Since the moving ring 501 is threadedly connected to the adjusting cylinder 502, and the guide block 8 slides inside the guide groove 9, the moving rings 501 are driven to move closer to each other, and the guide blocks 8 move closer to each other along the guide groove 9, so that the limiting ring 501 moves closer to each other. The positioning rings 4 are brought closer together until the limiting ring 4 is tightly attached to the surface of the mounting plate 1, thereby installing the support cylinder 2 at the opening of the mounting plate 1; then the arc probe 3 is passed through the adjusting cylinder 502. Next, the control ring 704 is rotated, which drives the push ring 703 to rotate forward inside the adjusting ring 6, so that the push ring 703 abuts against the inclined surface of the control groove 12, causing the fixing post 701 to move outward toward the outside of the arc probe 3 until the end of the fixing post 701 is close to the outer side of the arc probe 3. At this time, the return spring 702 is stretched and lengthened, thereby fixing the arc probe 3 on the mounting plate 1.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the adjustment mechanism 5 includes a moving ring 501 and an adjustment cylinder 502. The moving rings 501 are symmetrically arranged and are movably connected to the inside of the support cylinder 2. The outer side of the adjustment cylinder 502 has a set of symmetrical threads. The adjustment cylinder 502 passes through the moving rings 501 and is threadedly connected to the moving rings 501. The arc probe 3 passes through the adjustment cylinder 502 and is movably connected to the adjustment cylinder 502. The adjustment cylinder 502 is movably connected to the inside of the support cylinder 2, and the two sides of the adjustment cylinder 502... Both ends extend to the outside of the support cylinder 2. The two ends of the adjusting cylinder 502 are fixedly connected to the adjusting ring 6. Several guide blocks 8 are fixedly connected to the outside of the moving ring 501, and the guide blocks 8 are distributed in a circular array. Multiple sets of symmetrical guide grooves 9 are opened on the outside of the support cylinder 2. The guide blocks 8 are movably connected to the guide grooves 9 respectively. The opposite sides of the limiting ring 4 are engaged with each other, and the opposite sides of the limiting ring 4 are fixedly connected to the positioning pins 10. The outer side of the guide block 8 is provided with positioning holes 11, and the positioning pins 10 are adapted to the positioning holes 11.

[0029] Rotating the adjusting ring 6 causes the adjusting cylinder 502 to rotate inside the support cylinder 2. Since the moving ring 501 is threadedly connected to the adjusting cylinder 502 and the guide block 8 slides inside the guide groove 9, the moving rings 501 are driven to move closer to each other, and the guide blocks 8 move closer to each other along the guide groove 9, so that the limiting rings 4 move closer to each other until the limiting rings 4 are tightly fitted to the surface of the mounting plate 1, thereby installing the support cylinder 2 at the opening of the mounting plate 1. This is convenient for mounting plates 1 of different thicknesses and different opening sizes, and the installation and disassembly are relatively simple.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the fixing mechanism 7 includes a fixing post 701, a return spring 702, a push ring 703, and a control ring 704. The push ring 703 is fixedly connected to one side of the control ring 704. The fixing post 701 and the return spring 702 are both arranged in a circular array. The fixing post 701 is movably connected to the inside of the adjusting ring 6, and one end of the fixing post 701 is in contact with the outside of the arc probe 3. The bottom end of the return spring 702 is fixedly connected to the top end of the fixing post 701, and the top end of the return spring 702 is fixedly connected to the inside of the adjusting ring 6. The outside of the push ring 703 is threaded, and the push ring 703 is movably connected to the inside of the adjusting ring 6 through the threaded rotation. The outside of the fixing post 701 is provided with a control groove 12, and the inner side of the control groove 12 is constructed with an inclined surface. The end of the push ring 703 abuts against the inclined surface of the control groove 12.

[0031] The arc probe 3 is inserted through the adjusting cylinder 502. Then, the control ring 704 is rotated, which drives the push ring 703 to rotate forward inside the adjusting ring 6. As a result, the push ring 703 abuts against the inclined surface of the control groove 12, causing the fixing post 701 to move outward toward the outside of the arc probe 3 until the end of the fixing post 701 is in close contact with the outer side of the arc probe 3. At this time, the return spring 702 is stretched and lengthened, thereby fixing the arc probe 3 onto the mounting plate 1. This helps to improve the stability of the arc probe 3 installation and reduce the positional displacement of the arc probe 3 caused by external impact.

[0032] Working principle: In use, firstly, the support cylinder 2 passes through the opening of the mounting plate 1. Then, the positioning pin 10 on the inner side of the limiting ring 4 engages with the positioning hole 11 on the outer side of the moving ring 501, thereby fixing the limiting ring 4 to the outer side of the moving ring 501. The limiting ring 4 is located on both sides of the mounting plate 1. Then, the adjusting ring 6 is rotated, causing the adjusting cylinder 502 to rotate inside the support cylinder 2. Since the moving ring 501 is threadedly connected to the adjusting cylinder 502, and the guide block 8 slides inside the guide groove 9, the moving rings 501 are driven to move closer to each other, and the guide blocks 8 move closer to each other along the guide groove 9. The limiting rings 4 are brought closer together until they are tightly fitted to the surface of the mounting plate 1, thereby installing the support cylinder 2 at the opening of the mounting plate 1; then the arc probe 3 is passed through the adjusting cylinder 502. Next, the control ring 704 is rotated, which drives the push ring 703 to rotate forward inside the adjusting ring 6, so that the push ring 703 abuts against the inclined surface of the control groove 12, causing the fixing post 701 to move towards the outside of the arc probe 3 until the end of the fixing post 701 is close to the outer side of the arc probe 3. At this time, the return spring 702 is stretched and lengthened, thereby fixing the arc probe 3 on the mounting plate 1.
