Description

Technical Field

[0001] This utility model belongs to the field of surge arrester monitoring technology, specifically relating to a zinc oxide surge arrester monitoring device. Background Technology

[0002] The zinc oxide surge arrester monitoring device is a specialized instrument used for on-site and laboratory testing of various relevant electrical parameters of zinc oxide surge arresters. It is an instrument used in conjunction with zinc oxide surge arresters in high-voltage AC power systems. The instrument is connected in series in the surge arrester's grounding circuit. The milliammeter in the monitor is used to monitor the leakage current (peak value) through the surge arrester under operating voltage, which can determine whether the surge arrester is damp or whether the components are abnormal.

[0003] Chinese patent CN210514479U discloses an anti-interference zinc oxide surge arrester monitoring device. The voltage acquisition circuit includes a voltage extraction circuit, a low-pass filter, and a polarity conversion circuit connected in sequence. The voltage extraction circuit can obtain accurate voltage values. The voltage extraction circuit also includes a current-limiting resistor, a protective diode, and an anti-interference capacitor to filter out large-amplitude interference signals and noise at the front end. The low-pass filter filters out high-frequency interference and most high-order harmonics, improving the signal-to-noise ratio. The polarity conversion circuit converts AC power into a square wave signal with a peak value of 0-5V, making it easily received by the processor's A / D converter.

[0004] The above-mentioned device employs technical means to prevent interference with the monitoring device. However, when using the above-mentioned device, dust and rainwater are easily attached to the surface of the main body of the monitoring instrument. Dust and rainwater can easily enter the interior of the main body of the monitoring instrument through the gaps in the glass cover and the housing, thereby affecting the function of the internal components. The existing testing device does not have a certain dustproof and rainproof structure. Therefore, a new type of zinc oxide surge arrester monitoring device is needed to improve the above-mentioned device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a zinc oxide surge arrester monitoring device, which has the advantages of being dustproof and rainproof. It solves the problem that when the monitoring device is exposed, dust and rainwater can easily enter the main body of the monitoring device through the gaps in the glass cover and the housing, thereby affecting the function of the internal components.

[0006] To achieve the above-mentioned purpose of dust and rain protection for the monitoring device, this utility model provides the following technical solution: a zinc oxide surge arrester monitoring device, including a monitoring device body, a protective component provided on the outer cover of the monitoring device body, and a cleaning component installed on the protective component;

[0007] The protective assembly includes a base fixed to the bottom of the monitoring device body, an annular groove is chiseled at the top of the base, a protective cover is threaded into the annular groove, and multiple drainage grooves are equidistantly arranged on the side wall of the annular groove.

[0008] The cleaning component includes a connector fixedly connected to the upper side wall of the protective cover, a rotating shaft rotatably connected to the top of the connector, a support plate rotatably connected to the end of the rotating shaft away from the connector, and a cleaning cotton fixedly connected to the bottom of the support plate, with the cleaning cotton abutting against the top of the protective cover.

[0009] Furthermore, a connecting block is fixedly connected to one end of the rotating shaft near the support plate, and a clamping plate is fixedly connected to one end of the support plate near the connecting block.

[0010] Furthermore, the connecting block has symmetrically carved inner grooves at both ends, and the inner wall of the card plate is symmetrically fixed with card shafts corresponding to the inner grooves, and the card shafts are engaged and rotated with the card plate.

[0011] Furthermore, a storage box is fixedly connected to the side wall of the connector, and the top of the storage box has a slot that matches the height of the connector block.

[0012] Furthermore, the support plate is designed to be detachable by splitting into two halves in the middle. A locking block is fixedly connected to the side of one half of the support plate located at one end of the locking plate, and a locking groove corresponding to the locking block is opened on the side of the other half of the support plate, and the locking block and the locking groove are engaged.

[0013] Furthermore, both the top of the card block and the card slot are provided with corresponding screw holes, and bolts are connected to the internal threads of the screw holes.

[0014] Furthermore, the protective cover is made of transparent acrylic, and the bolts are made of plastic.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, this utility model, by setting up protective and cleaning components, inserts the protective cover into the annular groove and fixes it with threads, which can protect and shield the main body of the monitoring device. The protective cover is made of transparent acrylic material, which does not affect the viewing of the data on the main body of the monitoring device. Even in rainy weather, rainwater flowing from the protective cover into the annular groove can be discharged from the drainage channel without causing water accumulation. When the protective cover is covered with dust for a long time, the support plate can drive the cleaning cotton to rotate back and forth through the rotating shaft and connecting seat, so that the cleaning cotton rubs against the surface of the protective cover to clean the dust, thereby maintaining the transparency of the protective cover and effectively achieving the overall protection of the main body of the monitoring device, providing dust and rain protection.

[0017] 2. In use, this utility model features a storage box. When the cleaning cotton is not in use, the bolts can be manually loosened to remove the clips from the slots, thus disassembling the support plate into two halves.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please see Figure 1-2 This utility model provides a technical solution: a zinc oxide surge arrester monitoring device, including a monitoring device body 1, characterized in that: the monitoring device body 1 is covered with a protective component 2, and a cleaning component 3 is installed on the protective component 2;

[0027] The protective component 2 includes a base 201 fixed to the bottom of the monitoring device body 1. An annular groove 202 is chiseled at the top of the base 201. A protective cover 203 is threaded into the annular groove 202. Multiple drainage grooves 204 are equidistantly provided on the side wall of the annular groove 202.

[0028] The cleaning component 3 includes a connector 301 fixedly connected to the upper side wall of the protective cover 203. A rotating shaft 304 is rotatably connected to the top of the connector 301. A support plate 302 is rotatably connected to the end of the rotating shaft 304 away from the connector 301. A cleaning cotton 303 is fixedly connected to the bottom of the support plate 302, and the cleaning cotton 303 abuts against the top of the protective cover 203. The protective cover 203 is made of transparent acrylic material, and the bolt 312 is made of plastic material.

[0029] By setting up the protective component 2 and the cleaning component 3, the protective cover 203 is inserted into the annular groove 202 and fixed with threads, which can protect and shield the main body 1 of the monitoring device. The protective cover 203 is made of transparent acrylic material, which does not affect the viewing of the data on the main body 1 of the monitoring device. Even in rainy weather, rainwater flows from the protective cover 203 into the annular groove 202 and can be discharged from the drainage channel 204, without causing water accumulation. When the protective cover 203 is covered with dust for a long time, the support plate 302 can drive the cleaning cotton 303 to rotate back and forth through the rotating shaft 304 and the connecting seat 301, so that the cleaning cotton 303 rubs against the surface of the protective cover 203 to clean the dust, thereby maintaining the transparency of the protective cover 203 and effectively achieving the overall protection of the main body 1 of the monitoring device, providing dust and rain protection.

[0030] like Figure 3-5A connecting block 305 is fixedly connected to one end of the rotating shaft 304 near the support plate 302. A clamping plate 307 is fixedly connected to one end of the support plate 302 near the connecting block 305. The connecting block 305 has symmetrically carved inner grooves 306 at both ends. Clamping shafts 308 corresponding to the inner grooves 306 are symmetrically fixedly connected to the inner wall of the clamping plate 307, and the clamping shafts 308 and the clamping plate 307 are engaged and rotatably connected. A storage box 4 is fixedly connected to the side wall of the connecting seat 301, and the top of the storage box 4 has a connection point for connecting... The support plate 302 is designed to be detachable with a matching height to the support plate 305. The half of the support plate 302 located at one end of the plate 307 is fixedly connected to the side of the support plate 302 with a locking block 309. The other half of the support plate 302 has a slot 310 corresponding to the locking block 309 on its side, and the locking block 309 engages with the slot 310. The top of both the locking block 309 and the slot 310 has a corresponding screw hole 311, and the screw hole 311 is internally threaded with a bolt 312.

[0031] By setting up the storage box 4, when the cleaning cotton 303 is not in use, the bolt 312 can be manually loosened to remove the clip 309 from the slot 310, thereby disassembling the support plate 302 into two halves. Then, the connecting seat 301 drives the support plate 302 to rotate and fold 90 degrees so that it is perpendicular to the connecting seat 301. Then, the rotating shaft 304 can be rotated to insert the support plate 302 into the clip and store it in the storage box 4. At this time, the disassembled half of the cleaning cotton 303 is inserted into the storage box 4, and the two halves of the cleaning cotton 303 are stacked on top of each other in the storage box 4, effectively achieving the effect of storing the cleaning cotton 303 when it is not in use and avoiding exposure and damage.

[0032] The working principle of the above embodiment is as follows: Compared with the prior art, inserting the protective cover 203 into the annular groove 202 and fixing it with threads can protect and shield the monitoring device body 1. The protective cover 203 is made of transparent acrylic material, so it does not affect the viewing of data on the monitoring device body 1. Even in rainy weather, rainwater flowing from the protective cover 203 into the annular groove 202 can be discharged through the drainage channel 204, preventing water accumulation. Furthermore, when the protective cover 203 becomes covered in dust due to lack of cleaning, the support plate 302 can drive the cleaning cotton 303 to rotate back and forth through the rotating shaft 304 and the connecting seat 301, causing the cleaning cotton 303 to rub against the surface of the protective cover 203, cleaning the dust and maintaining the transparency of the protective cover 203. This effectively achieves overall protection of the monitoring device body 1. The device provides protection against dust and rain. When the cleaning cotton 303 is not in use, the bolt 312 can be manually removed, and the clip 309 can be pulled out of the slot 310, thus disassembling the support plate 302 into two halves. Then, the connecting seat 301 drives the support plate 302 to rotate and fold 90 degrees so that it is perpendicular to the connecting seat 301. Then, the rotating shaft 304 can be rotated to rotate the support plate 302 into the clip and store it in the storage box 4. At this time, the disassembled half of the cleaning cotton 303 is inserted into the storage box 4, and the two halves of the cleaning cotton 303 are stacked on top of each other in the storage box 4. This effectively achieves the effect of storing the cleaning cotton 303 when it is not in use, avoiding exposure and damage, improving the practicality of the monitoring device, and solving the problem that the existing technology does not have dust and rain protection functions.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
