Description

Technical Field

[0001] The invention relates to the technical field of hydraulic oil detection auxiliary devices, and in particular to an automatic shaking and transmission device for transformer oil samples. Background Art

[0002] In recent years, with the rapid development of social economy, people's demand for power grid upgrading and high-speed rail construction has been increasing. At the same time, power transformers, as the link of power transmission and distribution systems, have also received more and more attention. According to the State Grid Operation Analysis Report, in recent years, as the voltage level of the power system has continued to increase, people have put forward higher requirements for the stable operation of transformers, and therefore require the insulating medium to have better insulation and heat dissipation performance.

[0003] At present, most of the existing transformers use oil-paper insulation, in which the transformer oil plays the role of heat dissipation and insulation at the same time. At present, with the increase of the transformer level, the losses generated by the iron core, windings and some metal structures of the transformer during operation are increasing, and these losses are converted into heat and transferred to the surrounding medium. This also means that higher requirements are placed on the heat dissipation of the transformer, so it is necessary to conduct research on the enhanced heat transfer of existing transformers. However, if the thermal conductivity of the transformer oil is not changed, it can only be achieved by increasing its heat dissipation space, which is obviously not conducive to the development of the transformer in the direction of miniaturization;

[0004] In order to solve the heat dissipation optimization problem of transformer oil, Choi et al. of Argonne National Laboratory in the United States first proposed the concept of nanofluid in 1995, by evenly dispersing nano metal or non-metal oxide particles into transformer oil to form a stable nanoparticle suspension. This new functional fluid has improved thermal conductivity compared to pure transformer oil, and its heat dissipation capacity is also improved accordingly. Nano silicon dioxide particles are cheap, and their thermal conductivity is 27W / m·K, while the thermal conductivity of transformer oil is 0.1W / m·K. Dispersing nano silicon dioxide into transformer oil can effectively improve the thermal conductivity of transformer oil. The key to improving the thermal conductivity of modified transformer oil lies in the dispersion stability of nano silicon dioxide in transformer oil.

[0005] Since the antioxidant capacity of transformer base oil itself is limited, it is usually necessary to add an appropriate amount of antioxidant to transformer oil to extend the service life of transformer oil. However, most industrial antioxidants have potential environmental threats, and some antioxidants have adverse effects on breakdown voltage and oil flow charging. These all limit the use of antioxidants in transformer oil.

[0006] Nano-modified transformer oil has been a hot topic in transformer oil research in recent years. Studies have shown that nanoparticles can improve the thermal conductivity and heat transfer efficiency of transformer oil; on the other hand, due to the interface effect at the nanoscale, nanoparticles will not only not destroy the insulation properties of transformer oil, but will help improve its withstand voltage strength; studies have shown that nanomaterials can significantly improve the withstand voltage performance of transformer oil when it ages. At present, there is no research on using nanomaterials to improve the anti-aging properties of transformer oil.

[0007] CN105754702A discloses a system for recovering the performance of waste transformer oil and a treatment method thereof. The system includes an oil supply pump, a vacuum treatment device, an adsorption regeneration device, a two-stage fine filtration device and an electric control box. The present invention integrates a coarse filtration device, a two-pole fine filtration device, a heating and temperature raising device, a vacuum treatment device and an adsorption regeneration device to achieve system integration, and can perform coarse filtration, two-pole fine filtration, vacuum dehydration and degassing filtration and adsorption regeneration filtration on the waste transformer oil. The waste transformer oil can be subjected to a full range of filtration treatment, so that the cleanliness, water content, gas content, acid value, dielectric loss, pressure resistance and other indicators of the transformer oil meet the standards of new oil.

[0008] CN1483793A discloses a method for recycling power transformer oil, which first filters the transformer oil to remove solid impurities, then places the oil in a sealed tank and performs a vacuum treatment on it, and finally performs a needle electrode discharge test and then seals and fills it. The treated oil can be dehydrated in one go, with less residual water, high insulation strength, and simple and convenient operation;

[0009] The above two patents only provide a method for processing transformer oil, but do not disclose how to shake the sample.

[0010] In order to ensure the use effect of transformer oil, multiple samples are generally taken for testing after the purchase of new materials, transformer oil in use, adding antioxidants or filtering. Before the transformer oil sample is analyzed for pH, the transformer oil sample needs to be fully mixed with the reagent in the test tube. The current shaking method is manual shaking, or manually placing the test tubes one by one on the machine to shake, and then manually removing them after shaking, which is relatively cumbersome. Summary of the invention

[0011] In order to overcome the shortcomings of the prior art, the technical problem to be solved is: to provide a transformer oil sample automatic shaking and transmission device, which can automatically shake and accurately control the number of times and angles of the test tube shaking, and reduce manual operation steps;

[0012] The current shaking method is manual shaking, or manually placing the test tubes one by one on the machine to shake, and then manually removing them after shaking. Manual shaking cannot accurately control the number and angle of shaking, and the machine shaking steps are cumbersome and wasteful. This device mainly realizes the function of automatic shaking of test tubes, and can fully control the angle and number of shaking of test tubes, ensure that all test tubes are shaken consistently, and realize automatic entry into the transmission system after shaking to enter the next link, reducing the steps of manual operation;

[0023] The shaking box is adapted to the test tube chute; the shaking box is rotationally connected to the shaking motor seat; and the swing structure is arranged between the shaking motor seat and the shaking box.

[0024] Furthermore, the swing structure also includes a stepper motor fixedly connected to the shaking motor base, a turntable whose center is fixedly connected to the output end of the stepper motor, and a rocker with one end hinged to the edge of the turntable; the other end of the rocker is hinged to the shaking box.

[0025] The inner side of the shaking box is provided with a first shaking plate, a second shaking plate, a third shaking plate and a fourth shaking plate;

[0026] The other side of the interior of the shaking box is provided with a fifth shaking plate, a sixth shaking plate and a seventh shaking plate;

[0031] The beneficial effects of the present invention are:

[0032] 1. The transformer oil and reagent in the test tube can be shaken evenly by the setting of the shaking structure.

[0058] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0059] Example 1

[0060] like Figure 1-7 As shown,

[0061] A transformer oil sample automatic shaking and conveying device comprises a base plate 1, a shaking motor seat 8 fixedly mounted on one side of the base plate 1, a test tube chute 2 fixedly mounted on the base plate 1, a shaking structure mounted on the shaking motor seat 8, a paddle assembly mounted on the base plate 1 and used to control the test tube to enter the shaking structure from the test tube chute 2, and a test tube receiving and conveying device mounted below the shaking structure;

[0062] like Figure 4 As shown, the bottom plate 1 is provided with a feeding port 101 for the test tube;

[0063] The feeding port 101 is in the shape of a long strip, and its width is adapted to the diameter of the test tube;

[0064] like Figure 1 As shown, the feeding port 101 is located above the test tube chute 2, which is convenient for the test tube to enter the test tube chute 2;

[0065] like Figure 1 As shown, the bottom plate 1 is arranged horizontally, and the shaking motor seat 8 is vertically connected to the bottom plate 1 by welding;

[0066] The shaking motor seat 8 is located at the rear half of the bottom plate 1, so that the test tube chute 2 and other mechanisms can be installed at the front half of the bottom plate 1;

[0067] The test tube chute 2 is fixedly connected to the bottom surface of the bottom plate 1 through the chute fixing plate 3; the downward tilt angle of the test tube chute 2 is ensured so that the test tube can slide freely in the test tube chute 2.

[0068] like Figure 1As shown, the chute fixing plate 3 is composed of four vertical plates, which are respectively arranged on both sides of the test tube chute 2; the top of the vertical plate is fixedly connected to the bottom plate 1 by bolts; the side of the vertical plate is fixedly connected to the two sides of the test tube chute 2 by bolts.

[0069] like Figure 1 As shown, the two vertical plates close to the feeding port 101 are shorter, and the two vertical plates away from the feeding port 101 are longer, so that the test tube chute 2 is installed obliquely on the chute fixing plate 3, which is convenient for the test tube to slide down.

[0070] A test tube outlet is provided at the lower part of the test tube chute 2 (far away from the feeding port 101 ), and a paddle assembly is provided at the test tube outlet. The paddle assembly is used to control the speed at which the test tube enters the shaking box 16 .

[0071] A first detection device is provided on the side of the bottom of the test tube chute 2;

[0072] The first detection device is used to detect whether a test tube enters the paddle assembly from the test tube chute 2; the first detection device is a first photoelectric switch 19;

[0073] The shaking motor base 8 is provided with a second detection device; the second detection device is a shaking box detection photoelectric switch 14;

[0074] The second detection device is used to detect whether a test tube enters the shaking structure;

[0075] The first detection device, the second detection device and the paddle assembly are connected to the control device by signals.

[0076] The angle between the test tube chute 2 and the horizontal plane is 15-25 degrees;

[0077] The preferred angle is 20 degrees, which can ensure that the test tube automatically slides out of the test tube chute 2.

[0078] like Figure 5 As shown, the paddle assembly includes an electromagnet base plate 7 mounted on a base plate 1, an electromagnet 4 mounted on the electromagnet base plate 7, an electromagnet telescopic rod 5 mounted in the electromagnet 4, a connecting rod 62 with one end of which rotates and slides with the electromagnet telescopic rod 5, and a paddle 6 fixedly connected to the other end of the connecting rod 62;

[0079] like Figure 7 As shown, the cross section of the paddle 6 is semi-cylindrical, and the inner diameter of the cylinder of the paddle 6 matches the outer diameter of the test tube;

[0080] The lower end of the paddle 6 is provided with a chamfer 65, so as to minimize the contact area between the paddle 6 and the test tube and reduce resistance when the test tube enters the inner cavity of the paddle 6.

[0081] The electromagnet telescopic rod 5 and the connecting rod 62 can rotate and slide, so when the paddle 6 is to pull down the test tube that is in contact with it, the paddle 6 needs to rotate to wrap the test tube, and then the paddle 6 moves again to pull down the test tube.

[0082] like Figure 5-7 As shown, the paddle 6 is provided with a paddle shaft 61 rotatably connected to the electromagnet bottom plate 7; the arc outer diameter of the paddle 6 is adapted to the test tube chute 2; and the electromagnet 4 is connected to the control device signal.

[0083] The top of the paddle 6 is closed, and the paddle shaft 61 is fixed at the top center of the paddle 6, that is, the paddle shaft 61 is concentric with the paddle 6;

[0084] The electromagnet telescopic rod 5 is provided with a long slot, the connecting rod 62 is inserted into the long slot, and the connecting rod 62 is rotated with the electromagnet telescopic rod 5 through a rotating pin 63;

[0085] like Figure 6 , 7 As shown, a slide groove 64 is provided on the connecting rod 62, and the rotating pin 63 can rotate in the slide groove 64 or slide along the slide groove 64;

[0086] A spring connected to the electromagnet telescopic rod 5 is arranged inside the electromagnet 4. When the electromagnet is powered, the electromagnet telescopic rod 5 overcomes the resistance of the spring and contracts. The electromagnet telescopic rod 5 pulls the connecting rod 62 to move rightward. The connecting rod 62 drives the paddle 6 to rotate around the paddle rotating shaft 61 on the electromagnet bottom plate 7. The bottom end of the paddle 6 rotates in the test tube chute 2 to release a test tube. Then the electromagnet 4 loses power, and the electromagnet telescopic rod 5 pops out under the action of the spring, pushing the paddle 6 to reset and block the next test tube.

[0087] The shaking structure includes a shaking box 16 for shaking the test tube and a swinging structure for driving the shaking box 16 to shake;

[0088] The shaking box 16 is located below the test tube chute 2, so that the test tube can enter the shaking box 16 from the test tube chute 2 under the action of gravity;

[0089] The shaking box 16 is rotatably connected to the shaking motor base 8 ; the swing structure is arranged between the shaking motor base 8 and the shaking box 16 .

[0090] The swing structure includes a stepper motor 11 fixedly connected to the shaking motor seat 8, a turntable 12 whose center is fixedly connected to the output end of the stepper motor 11, and a rocker 13 with one end hinged to the edge of the turntable 12; the other end of the rocker 13 is hinged to the shaking box 16.

[0091] The swing structure is similar to a common crank connecting rod structure. The working process is that when the test tube falls into the shaking box 16, the stepper motor 11 rotates, the stepper motor 11 drives the turntable 12 to rotate, and the edge of the turntable 12 drives one end of the rocker 13 to rotate around the center of the turntable 12; the other end of the rocker 13 pulls one side of the shaking box 16 to swing around the rotation center of the shaking box 16 and the shaking motor base 8, thereby realizing the swinging of the shaking box 16. The transformer oil and reagent in the test tube can be shaken.

[0092] like Figure 4 As shown, a first shaking plate 161, a second shaking plate 162, a third shaking plate 163 and a fourth shaking plate 164 are provided on one side of the interior of the shaking box 16;

[0093] The other side of the interior of the shaking box 16 is provided with a fifth shaking plate 165, a sixth shaking plate 166 and a seventh shaking plate 167;

[0094] The shaking plates on both sides of the shaking box 16 are staggered, and the opposite end of the shaking plate is tilted downward to facilitate the test tube to slide down step by step; the tilt angle is not less than 15 degrees and not more than 20 degrees to avoid the angle being too small to make it difficult to slide, and the angle being too large to slide too fast and unable to shake evenly.

[0095] One end of the shaking plate is fixedly connected to the shaking box; the other end of the shaking plate is open, and the open end of the shaking plate is lower than the fixed end, so that the test tube can slide down easily.

[0096] A buckle 10 is provided at the lower end of the shaking box 16. When the shaking is finished, the buckle 10 is opened to release the test tube to the receiving box.

[0097] After the test tube is pushed down from the test tube chute 2 by the paddle 6, it falls on the first shaking plate 161, shakes on the first shaking plate 161, slides onto the fifth shaking plate 165, and then slides onto the second shaking plate 162, the sixth shaking plate 166, the third shaking plate 163, the seventh shaking plate 167, the fourth shaking plate 164 in sequence, and finally falls on the buckle 10.

[0098] The spacing between adjacent shaking plates should be larger than the outer diameter of the test tube. Generally, this spacing is about twice the outer diameter of the test tube to prevent the test tube from getting stuck.

[0099] The test tube receiving and conveying device comprises a receiving box 17 arranged below the shaking box 16 and a belt 18 for driving the receiving box 17 to move.

[0100] The working process of the present invention,

[0101] The operator puts the test tube into the test tube chute 2 from the feeding port 101 of the bottom plate 1, and the test tube slides along the test tube chute 2 to the bottom outlet position, and the outlet position is limited by the electromagnet 4 driving the specific paddle 6; a first photoelectric switch 19 is provided on the side of the bottom of the test tube chute 2; when the test tube needs to be released, the electromagnet 4 is energized, the electromagnet telescopic rod 5 is attracted, and the paddle 6 is driven to rotate through the connecting rod 62 to release the test tube;

[0102] There is a shake box detection photoelectric switch 14 on the shake motor base 8. When the first photoelectric switch 19 detects that there is a test tube at this position, and the shake box detection photoelectric switch 14 detects that the test tube shake box 16 swings to this position. The electromagnet 4 drives the paddle 6 to open, releases the test tube in the front and blocks the test tube in the back, so that the test tubes automatically fall into the test tube shake box below one by one. The shake box 16 is swung by the rocker 13 driven by the stepping motor 11. A 7-level shaking plate is arranged inside the shake box 16. The test tube slides step by step on the shaking plate inside the shake box 16. During the swinging process of the shake box 16, the test tube swings back and forth to achieve the fusion of the internal transformer oil and the reagent, completing the shaking action. After the 7-level swing, the test tube enters the test tube receiving box 17 from the outlet and is transported to the subsequent system by the conveyor belt 18.

[0105] The difference is that

[0106] The driving device of the belt 18 is an electric slide, which is a standard part and easy to match.

[0107] Example 3

[0108] The structure of this embodiment is basically the same as that of embodiment 1.

[0109] The difference is that, Figure 1 As shown,

[0110] The driving device of the belt 18 includes a frame, a motor mounted on the frame, a pulley at the output end of the motor, a conveying roller rotatably connected to the frame, a driven pulley mounted at the end of the conveying roller, and a V-belt connected between two pulleys; the number of the conveying rollers is greater than or equal to two, and the belt 18 is sleeved on the conveying rollers. The shaken test tube is sent to a suitable position through the belt 18.
