Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a multi-gas synchronous detection mechanism for an integrated calibration device for dissolved gases in oil. Background Technology

[0002] Dissolved gas analysis in oil is one of the most convenient and effective methods for identifying early latent faults in oil-immersed power transformers, and it has promising applications in online assessment of transformer operating conditions and prediction of remaining life. Rapid and accurate analysis of the composition and content of dissolved gases in the oil is the prerequisite and key to this method. With the development of optical devices, spectroscopic analysis is gradually being applied to gas analysis in oil.

[0003] In the prior art, such as the optical spectrum measuring device for gases in transformer oil (publication number CN211785090U), the device body includes a gas chamber for storing various gases from transformer oil. The gas chamber's inlet is connected to an intake system for drawing the gases from the transformer oil into the chamber. The intake system includes an extraction component that directly extracts the gas from the transformer oil tank, and a cooling component for cooling the extracted gas. The extraction component includes an extraction pump, and the pump's input end is fitted with a filter nozzle via a pipe. This invention uses a dust filter to trap small amounts of impurities floating in the gas from the transformer oil tank, thus obtaining gas with higher purity. It also ensures that the gas introduced into the gas chamber does not carry heat, avoiding interference with subsequent refraction operations and ensuring the accuracy of subsequent spectral measurements.

[0004] The above technical solution has some problems in practical application. When calibrating the gas in transformer oil, the solution can only test a single gas at a time. When multiple gases need to be tested, the light source needs to be adjusted to emit lasers of different wavelengths. However, after the laser passes through the gas, some of the gas undergoes a photocatalytic reaction under the action of the laser, causing the gas to deteriorate and affecting the accuracy of subsequent tests. Therefore, it is impossible to test multiple gases.

[0005] Therefore, it is necessary to develop a multi-gas synchronous detection mechanism for an integrated oil dissolved gas testing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-gas synchronous detection mechanism for an integrated oil dissolved gas calibration device, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-gas synchronous detection mechanism for an integrated dissolved gas testing device in oil, comprising a detection box, wherein multiple detection boxes are horizontally and sequentially fixed inside the detection box, each detection box having a flat structure; an inlet pipe and an outlet pipe are fixedly fixed at both ends inside the detection box, and both ends of the multiple detection boxes are connected to the inlet pipe and the outlet pipe, respectively; two sliding blocks are slidably provided on both sides inside the detection box, and the two sliding blocks are respectively located on both sides of the multiple detection boxes; a laser emitter and a photoelectric sensor are fixedly fixed in the middle of the two sliding blocks, the laser emitter, the detection box, and the photoelectric sensor being in overlapping positions; a threaded sleeve is fixedly provided at the top of each of the two sliding blocks, and an adjusting screw is provided inside each of the two threaded sleeves via threads, and the two adjusting screws are rotatably located inside the detection box via bearings.

[0008] Preferably, one end of each of the two adjusting screws is fixedly provided with a transmission synchronous pulley, and a drive synchronous pulley is rotatably provided on the outside of the detection box, with a synchronous belt provided between the drive synchronous pulley and the transmission synchronous pulley.

[0009] Preferably, a knob is fixedly provided on the outer side of the drive synchronous pulley, a fixed cover is fixedly provided on the outer side of the detection box, and the transmission synchronous pulley, drive synchronous pulley and synchronous belt are all located inside the fixed cover.

[0010] Preferably, each of the two slide blocks has a sliding sleeve fixedly installed at its bottom end, and each of the two sliding sleeves has a sliding rod that can slide inside, and both sliding rods are fixedly installed inside the detection box.

[0012] Preferably, the inside of the testing box is fixedly provided with multiple partitions, and the multiple partitions are staggered with the multiple testing boxes.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model comprises a detection box, a sliding base, a laser emitter, and a photoelectric sensor. Multiple detection boxes are provided. When detecting gases in oil, the extracted gas is injected into multiple detection boxes through the air inlet pipe. The laser emitted by the laser emitter passes through the gas in the detection box and is captured by the photoelectric sensor to verify the gas. By adjusting the position of the sliding base, the laser emitter and photoelectric sensor are aligned with multiple sets of detection boxes, and the wavelength of the laser emitted by the laser emitter is adjusted, thus enabling the verification of multiple gases. Furthermore, each time the wavelength of the laser emitter is adjusted, it can be matched with an unverified detection box to avoid photocatalytic reactions in the gas within the detection box during the verification process, which could affect the verification accuracy. This ensures the accuracy of the device when verifying multiple sets of gases.

[0015] 2. This utility model, by setting a threaded sleeve and an adjusting screw, allows for the adjustment of the slide position through the cooperation of the threaded sleeve and the adjusting screw. The adjusting screw is driven by a transmission synchronous pulley, a drive synchronous pulley, a synchronous belt, and a knob. The user can quickly adjust the slide position by turning the knob, so as to facilitate the rapid switching of the laser emitter and photoelectric sensor between multiple detection boxes.

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.

[0022] This utility model provides, for example Figure 1-4 The multi-gas synchronous detection mechanism of the integrated oil dissolved gas calibration device shown includes a detection box 1. Multiple detection boxes 2 are horizontally fixed inside the detection box 1. All detection boxes 2 are designed as flat structures. An inlet pipe 3 and an outlet pipe 4 are fixed at both ends inside the detection box 1. Both ends of the multiple detection boxes 2 are connected to the inlet pipe 3 and the outlet pipe 4, respectively. It should be noted that valves are provided at the ends of the inlet pipe 3 and the outlet pipe 4. After the valves are closed, the gas between the multiple detection boxes 2 will not flow.

[0023] The detection box 1 has two sliding blocks 5 on each of its two sides, and the two sliding blocks 5 are respectively located on both sides of multiple detection boxes 2. A laser emitter 6 and a photoelectric sensor 7 are fixed in the middle of the two sliding blocks 5 respectively. The laser emitter 6, the detection box 2 and the photoelectric sensor 7 are in the same position. It should be noted that the laser emitter 6 and the photoelectric sensor 7 adopt the existing structure in the prior art. They are also equipped with a power supply, controller, processor and other structures, which form a meteorological spectrometer structure to realize the verification of gas.

[0024] Both slide blocks 5 have threaded sleeves 9 fixedly mounted on their top ends. Adjusting screws 10 are threadedly mounted inside each of the two threaded sleeves 9, and each adjusting screw 10 is rotatably mounted inside the testing box 1 via bearings. A transmission synchronous pulley 11 is fixedly mounted at one end of each adjusting screw 10. A drive synchronous pulley 12 is rotatably mounted on the outside of the testing box 1. A synchronous belt 13 is provided between the drive synchronous pulley 12 and the transmission synchronous pulley 11. A knob 14 is fixedly mounted on the outside of the drive synchronous pulley 12. A fixing cover 15 is fixedly mounted on the outside of the testing box 1. The transmission synchronous pulley 11, the drive synchronous pulley 12, and the synchronous belt 13 are all housed within the fixed cover 15. The fixed cover 15 is used to protect the transmission synchronous pulley 11, the drive synchronous pulley 12, and the synchronous belt 13. It should be noted that the transmission synchronous pulley 11, the drive synchronous pulley 12, and the synchronous belt 13 all adopt existing structures in the prior art. The outer sides of the transmission synchronous pulley 11 and the drive synchronous pulley 12 are provided with tooth grooves, and the inner side of the synchronous belt 13 is provided with teeth to ensure stable transmission between the transmission synchronous pulley 11, the drive synchronous pulley 12, and the synchronous belt 13.

[0025] The bottom ends of the two slide blocks 5 are fixedly provided with sliding sleeves 16, and the interior of the two sliding sleeves 16 is provided with sliding rods 17, and the two sliding rods 17 are fixed inside the detection box 1. The sliding rods 17 cooperate with the sliding sleeves 16 to ensure the stable sliding of the slide blocks 5.

[0026] The upper surface of the testing box 1 is provided with two strip-shaped observation windows 18, and the two observation windows 18 are respectively located above the two slides 5. The observation windows 18 are used to help the user determine the position of the slides 5.

[0027] Inside the detection box 1, there are multiple partitions 8 fixedly arranged, and the multiple partitions 8 are respectively arranged staggeredly with the multiple detection boxes 2. The partition 8 is used to prevent the multiple detection boxes 2 from affecting each other.

[0028] The working principle of the present utility model:

[0029] When this device is in use, first, transformer oil is extracted, and dissolved gas is extracted from the transformer oil by means of mechanical oscillation. Then, the dissolved gas is injected into the detection box 2 through the air inlet pipe 3. The dissolved gas fills the multiple detection boxes 2, and then the excess dissolved gas is discharged through the air outlet pipe 4. At this time, the valves at one end of the air inlet pipe 3 and the air outlet pipe 4 are closed, and the knob 14 is rotated, so that the knob 14 drives the driving synchronous wheel 12 to rotate. The driving synchronous wheel 12 drives the transmission synchronous wheel 11 to rotate through the synchronous belt 13. The transmission synchronous wheel 11 drives the adjusting screw 10 to rotate. The adjusting screw 10 cooperates with the threaded sleeve 9, so that the sliding seat 5 slides inside the detection box 1. The two groups of sliding seats 5 respectively drive the laser emitter 6 and the photoelectric sensor 7 to move, so that the laser emitter 6 and the photoelectric sensor 7 coincide with a group of detection boxes 2. At this time, the laser emitter 6 is controlled to emit laser with a certain wavelength. The laser passes through the gas in the detection box 2 and is captured by the photoelectric sensor 7. By analyzing the data through the processor supporting the photoelectric sensor 7, the verification of the gas can be completed.

[0030] When verifying multiple gases, the sliding seat 5 is slid by rotating the knob 14 until the laser emitter 6 and the photoelectric sensor 7 coincide with another group of detection boxes 2. The laser emitter 6 is controlled to emit laser with different wavelengths, and the data obtained by the photoelectric sensor 7 is analyzed, so as to realize the verification of different gases.

[0031] During the verification process, by changing the wavelength of the laser and according to the principle that the spectral images formed by different wavelengths of laser passing through different climates are different, different gases in the mixed dissolved gas can be verified. Moreover, the mixed gas in a single group of detection boxes 2 is only verified once, which can avoid the photocatalytic reaction of some gases affected by the laser and affect the verification accuracy.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
