Description

Technical Field

[0001] This utility model belongs to the field of discharge detection technology, and specifically relates to a metal partial discharge detection device. Background Technology

[0002] When electrical equipment experiences partial discharge, it generates electromagnetic waves. As these waves propagate outward, they produce a transient voltage signal to ground. The magnitude of this signal is directly related to the intensity of the partial discharge and the distance to the discharge point. This can be detected using a specialized detector, known as a partial discharge detector. Partial discharge detectors are widely used in power equipment and employ internationally prevalent methods such as the direct method, bridge balance method, or current pulse method to detect the discharge.

[0003] Existing patent: CN202322775440.1 A partial discharge detector has storage trays on both sides of the main body. The storage trays are driven by a motor to rotate and automatically store the cable, making it easy to carry. The storage trays are equipped with a protective cover and a flip cover. The flip cover can be opened and closed at will. After the cable is wrapped and stored, the flip cover closes to protect the cable.

[0004] However, when existing metal partial discharge (MMD) detection devices are used, there are usually no tables or other suitable places to place them at the work site. Therefore, the MDD detection devices are usually placed on the ground. When placed on the ground, the outer casing is easily contaminated with dirt, and dust stirred up by workers can easily fall into the device. Accumulated dirt can easily cause short circuits in the MDD detection device's circuitry. Furthermore, the above-mentioned solutions lack a support mechanism for the MDD detection device, which also leads to the same problems of the outer casing being easily contaminated with dirt and dust stirred up by workers falling into the device, thus reducing the practicality of the MDD detection device. Utility Model Content

[0005] In existing metal partial discharge (MMD) detection devices, the work site typically lacks a table or other suitable surface for placement. Therefore, the devices are usually placed on the ground, where their casing is easily contaminated with dirt. Furthermore, dust stirred up by workers can easily fall inside the device, leading to short circuits. The lack of a support structure in these solutions also contributes to the problem of easy contamination and dust accumulation, reducing the device's practicality. This invention proposes a metal partial discharge detection device to overcome these technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a metal partial discharge detection device, including a detector body. The outer surfaces of the left and right sides of the detector body are provided with mounting grooves extending out of their lower surfaces. A support shaft is rotatably connected between the inner walls of the front and rear sides of the mounting groove, and a positioning block is fixedly sleeved on the support shaft.

[0008] The detector body is provided with a positioning mechanism. The two opposite sides of the positioning mechanism slide into the positioning block respectively. The positioning mechanism slides into the positioning block to position the positioning block so that the positioning block can be positioned in a vertically upward state or a vertically downward state.

[0009] A limiting mechanism is provided in the mounting groove, which allows the mounting groove to rotate at a maximum angle of 180 degrees, thereby limiting the positioning block to rotate at a maximum angle of 180 degrees.

[0010] A support mechanism is slidably disposed within the positioning block. The support mechanism is used to support the main body of the detector and prevent the main body of the detector from directly contacting the ground during use.

[0011] Furthermore, the positioning mechanism includes two slide rail grooves, which are formed inside the main body of the detector. The two slide rail grooves extend into the two mounting grooves in opposite directions. A limiting block is slidably connected in the slide rail groove. Positioning grooves are formed on the outer surfaces of both sides of the positioning block. The end of the limiting block near the positioning block extends into the positioning groove.

[0012] Furthermore, the positioning mechanism also includes two slide grooves, which are formed on the front surface of the detector body. The two slide grooves communicate with the interior of two slide rail grooves. A push block is fixedly connected to the front surface of the limiting block, and the push block is slidably connected to the slide groove.

[0013] Furthermore, the positioning mechanism also includes a limiting spring, which is fixedly connected to the outer surface of the limiting block on the side away from the positioning block. The push block extends out of the front surface of the detector body through the slide groove, and the end of the limiting spring away from the limiting block is fixedly connected to the inner wall of the slide groove.

[0014] Furthermore, the positioning mechanism also includes two fixing rods, which are fixedly connected to the inner walls of the two adjacent mounting slots on both sides. The fixing rods are L-shaped. A connecting groove is provided on the lower surface of the positioning block, and the connecting groove extends out of the left and right outer surfaces of the positioning block. A spring is provided on the support shaft, and the inner end of the spring is fixedly connected to the outer surface of the support shaft, while the outer end of the spring is fixedly connected to the fixing rod.

[0015] Furthermore, the limiting mechanism includes two fixing plates, which are fixedly connected to the outer surfaces of the two support shafts. A limiting groove is provided on the rear inner wall of the mounting groove. The vertical cross-section of the limiting groove is a fan shape of 180 degrees. The fixing plates are slidably connected to the limiting groove.

[0016] Furthermore, the support mechanism includes two sliding blocks. The upper surface of the positioning block is provided with a positioning groove. The sliding block is slidably connected in the positioning groove. The sliding block extends out of the upper surface of the positioning block through the positioning groove. Multiple fixing holes are provided on the opposite outer surfaces of the two sliding blocks. Threaded rods are threadedly connected to the opposite outer surfaces of the two positioning blocks. The threaded rods are threaded through the positioning groove and slidably connected to the fixing holes.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model can use positioning blocks and sliding blocks to support the main body of the detector, so that the two sliding blocks are in contact with the ground, avoiding the main body of the detector being placed directly on the ground. On the one hand, it can prevent dirt from the ground from contaminating the main body of the detector, and on the other hand, it can prevent dust from falling into the main body of the detector during walking. Furthermore, the height of the support for the main body of the detector can be adjusted by adjusting the length of the sliding blocks extending out of the positioning blocks, thereby making the main body of the detector more flexible and practical.

[0019] 2. This utility model fixes the positioning blocks in a vertically downward position. At this time, the two positioning blocks are in contact with the ground and can support the main body of the detector, avoiding the main body of the detector from being placed directly on the ground. On the one hand, it can prevent dirt from the ground from contaminating the metal partial discharge detection device, and on the other hand, it can prevent dust from the ground from falling into the metal partial discharge detection device during walking, thereby improving the practicality and safety of the metal partial discharge detection device.

[0020] 3. The spring, fixing plate, and limiting groove of this utility model cooperate with each other, so that when the positioning block is vertically downward, the limiting block can still slide smoothly into the corresponding positioning groove on the positioning block, thereby improving the efficiency of using the positioning block and sliding block to support the main body of the detector, and thus increasing the practicality of the main body of the detector.

Detailed Implementation

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-6 As shown, this utility model is a metal partial discharge detection device, including a detector body 1. The outer surfaces of the left and right sides of the detector body 1 are provided with mounting grooves 2 extending out of their lower surfaces. A support shaft 3 is rotatably connected between the inner walls of the front and rear sides of the mounting groove 2. A positioning block 4 is fixedly sleeved on the support shaft 3.

[0034] The detector body 1 is provided with a positioning mechanism. The two opposite sides of the positioning mechanism slide into the positioning block 4 respectively. The positioning mechanism slides into the positioning block 4 and positions the positioning block 4 so that the positioning block 4 can be positioned in a vertically upward state or a vertically downward state.

[0035] A limiting mechanism is provided in the mounting groove 2, which makes the maximum rotation angle of the mounting groove 2 180 degrees, thereby limiting the maximum rotation angle of the positioning block 4 to 180 degrees.

[0036] A support mechanism is slidably disposed within the positioning block 4. The support mechanism is used to support the main body 1 of the detector and prevent the main body 1 of the detector from directly contacting the ground during use.

[0037] In the initial state, the positioning mechanism slides into the positioning block 4 and fixes the positioning block 4 in a vertically upward position. In use, the positioning mechanism is pushed to make relative movement. During the relative movement, the positioning mechanism slides out of the positioning block 4 to release the positioning fixation of the positioning block 4. At this time, the positioning block 4 is rotated 180 degrees so that the positioning block 4 is vertically downward. At this time, the positioning mechanism is released and reset. Under the action of the limiting mechanism, the positioning mechanism can still slide into the positioning block 4 after the positioning block 4 is rotated 180 degrees, thereby re-fixing and positioning the positioning block 4, so that the support mechanism remains in a vertically downward position. At this time, the support mechanism is in contact with the ground to support the main body 1 of the detector and prevent the main body 1 of the detector from directly contacting the ground during use.

[0038] In one embodiment, the positioning mechanism includes two slide rail grooves 16, which are formed inside the detector body 1. The two slide rail grooves 16 extend into the two mounting grooves 2 in opposite directions. A limiting block 17 is slidably connected in the slide rail groove 16. Positioning grooves 7 are formed on the outer surfaces of both sides of the positioning block 4. The end of the limiting block 17 near the positioning block 4 extends into the positioning groove 7.

[0039] The positioning mechanism also includes two slide grooves 14, which are formed on the front surface of the detector body 1. The two slide grooves 14 are connected to the interior of two slide rail grooves 16. A push block 15 is fixedly connected to the front surface of the limiting block 17, and the push block 15 is slidably connected to the slide groove 14.

[0040] The positioning mechanism also includes a limiting spring 18, which is fixedly connected to the outer surface of the limiting block 17 away from the positioning block 4. The push block 15 extends out of the front surface of the detector body 1 through the slide groove 14, and the end of the limiting spring 18 away from the limiting block 17 is fixedly connected to the inner wall of the slide groove 16.

[0041] The positioning mechanism also includes two fixing rods 12, which are fixedly connected to the inner walls of the two adjacent mounting slots 2. The fixing rods 12 are L-shaped. The lower surface of the positioning block 4 is provided with a connecting groove 5, which extends out of the left and right outer surfaces of the positioning block 4. A spring 13 is provided on the support shaft 3. The inner end of the spring 13 is fixedly connected to the outer surface of the support shaft 3, and the outer end of the spring 13 is fixedly connected to the fixing rods 12.

[0042] In addition, in specific applications, in the initial state, the spring 13 is in a tightened state, at which time the positioning block 4 is in a vertically upward state and both the positioning block 4 and the sliding block 8 are located in the mounting groove 2. At this time, the two opposing ends of the two limiting blocks 17 slide into the corresponding two positioning grooves 7. The limiting blocks 17 slide into the positioning grooves 7 to fix the state of the positioning block 4, so that the positioning block 4 cannot rotate.

[0043] When the main body 1 of the detector needs support, the two push blocks 15 are pushed relative to each other, so that the two push blocks 15 are closer to each other. At the same time, the two limiting blocks 17 fixed to the two push blocks 15 are also moved relative to each other. During this process, the limiting blocks 17 compress the limiting spring 18, so that the limiting spring 18 is deformed. At the same time, the limiting blocks 17 slide out of the positioning groove 7. At this time, the limiting blocks 17 do not position the positioning block 4. At this time, under the action of the release force of the spring 13, the support shaft 3 and the positioning block 4 are rotated. When the positioning block 4 rotates from vertically upward to vertically downward (rotation angle is 180 degrees), At this point, the two push blocks 15 are released, and under the release force of the limit spring 18, the limit block 17 and the push block 15 are reset, thereby causing the limit block 17 to slide into the corresponding positioning groove 7, thus fixing the vertical downward state of the positioning block 4. At this time, the two positioning blocks 4 are in contact with the ground, which can support the detector body 1 and prevent the detector body 1 from being placed directly on the ground. On the one hand, it can prevent dirt from the ground from contaminating the metal partial discharge detection device, and on the other hand, it can prevent dust from the ground from falling into the metal partial discharge detection device during walking, thereby improving the practicality and safety of the metal partial discharge detection device.

[0044] In one embodiment, the limiting mechanism includes two fixing pieces 9, which are fixedly connected to the outer surfaces of the two support shafts 3. A limiting groove 19 is provided on the rear inner wall of the mounting groove 2. The vertical cross-section of the limiting groove 19 is a fan shape of 180 degrees. The fixing pieces 9 are slidably connected to the limiting groove 19.

[0045] Furthermore, in practical applications, because the vertical cross-section of the limiting groove 19 is a fan shape of 180 degrees, and the fixing plate 9 is slidably connected to the limiting groove 19, the fixing plate 9 can only rotate 180 degrees around the support shaft 3 at most. Because the fixing plate 9 is fixedly connected to the support shaft 3, the support shaft 3 can also only rotate 180 degrees at most, thereby causing the positioning block 4 and the sliding block 8 to rotate only 180 degrees, that is, the positioning block 4 rotates from vertically upward to vertically downward; thus, it is easier for the limiting block 17 to slide into the corresponding positioning groove 7, thereby increasing the practicality of the detector body 1.

[0046] In one embodiment, the support mechanism includes two sliding blocks 8. The upper surface of the positioning block 4 is provided with a positioning groove 6. The sliding block 8 is slidably connected in the positioning groove 6. The sliding block 8 extends out of the upper surface of the positioning block 4 through the positioning groove 6. Multiple fixing holes 10 are provided on the opposite outer surfaces of the two sliding blocks 8. Threaded rods 11 are threadedly connected to the opposite outer surfaces of the two positioning blocks 4. The threaded rods 11 are threaded through the positioning groove 6 and are slidably connected to the fixing holes 10.

[0047] Furthermore, in specific applications, when positioning the positioning block 4 in its vertically downward position, the threaded rod 11 is rotated to slide out of the fixing hole 10. Then, the fixing hole 10 is pulled out from the positioning groove 6 to a suitable length. After that, the threaded rod 11 is rotated again to slide into the suitable fixing hole 10, thereby fixing the sliding block 8. At this time, the positioning block 4 and the sliding block 8 can be used to support the detector body 1, so that the two sliding blocks 8 are in contact with the ground, preventing the detector body 1 from being placed directly on the ground. This can prevent dirt from the ground from contaminating the detector body 1 and also prevent dust from falling into the detector body 1 during walking. Moreover, the height of the support for the detector body 1 can be adjusted by adjusting the length of the sliding block 8 extending out of the positioning block 4, making the detector body 1 more flexible and practical.

[0048] In this design, the function of the spring 13 is to ensure that the positioning block 4 is vertically downward when the spring 13 is not under force. This works in conjunction with the fixing plate 9 and the limiting groove 19 to allow the limiting block 17 to slide smoothly into the corresponding positioning groove 7 on the positioning block 4 when the positioning block 4 is vertically downward. This improves the efficiency of supporting the detector body 1 using the positioning block 4 and the sliding block 8, thereby increasing the practicality of the detector body 1.

[0049] In this solution, the detector body 1 is the prior art in the existing published patent: a partial discharge detector CN202322775440.1, which will not be elaborated here.

[0050] Through the above technical solution, 1. The detector body 1 can be supported by the positioning block 4 and the sliding block 8, so that the two sliding blocks 8 are in contact with the ground, avoiding the detector body 1 from being placed directly on the ground. On the one hand, it can avoid dirt from the ground from contaminating the detector body 1, and on the other hand, it can prevent dust from the ground from falling into the detector body 1 during walking. Furthermore, the height of the support for the detector body 1 can be adjusted by adjusting the length of the sliding block 8 extending into the positioning block 4, thereby making the detector body 1 more flexible and practical.

[0051] 2. By fixing the positioning blocks 4 in a vertically downward position, the two positioning blocks 4 can support the detector body 1 in contact with the ground, preventing the detector body 1 from being placed directly on the ground. This can prevent dirt from the ground from contaminating the metal partial discharge detection device and also prevent dust from falling into the metal partial discharge detection device during walking, thereby improving the practicality and safety of the metal partial discharge detection device.

[0052] 3. The spring 13 cooperates with the fixing plate 9 and the limiting groove 19 to facilitate the smooth sliding of the limiting block 17 into the corresponding positioning groove 7 on the positioning block 4 when the positioning block 4 is vertically downward, thereby improving the efficiency of supporting the detector body 1 with the positioning block 4 and the sliding block 8, and thus increasing the practicality of the detector body 1.
