Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of substation-level oil storage tank design, and particularly relates to a substation multi-scene alarm emergency treatment system. BACKGROUND

[0002] Designing a good accident oil tank is an important measure to protect electrical equipment and avoid pollution of the natural environment caused by oil discharge. According to the fire protection specification of China, transformers and oil-immersed electrical equipment with indoor single oil volume of more than 100 kg and outdoor single oil volume of more than 1000 kg shall be provided with oil storage pits and oil discharge facilities. Therefore, various accident oil tanks have appeared, such as the Chinese patent with the patent name of a kind of oil-water separation storage tank with suspended plate, which is authorized and announced as CN207324164U. The suspended plate is arranged below the oil discharge port, and mainly plays a buffering and auxiliary oil-water separation role. If oil and water directly drip into the liquid due to gravity, it will sink, so the oil may be directly discharged from the drain pipe. By increasing the suspended plate, the oil and water directly dripped on the suspended plate, and the oil and water slowly flowed into the liquid along the edge of the suspended plate, so that this phenomenon will not occur. Therefore, the original traditional oil storage tank is optimized, the oil-water separation time is short, the oil-water separation is more complete, the drainage is more standard, and finally the drainage is achieved through overflow. The deficiency of this technical solution is that the oil and water cannot be separated in advance, and the oil and water are mixed and discharged into the same oil tank, which increases the sewage treatment capacity and the tonnage of oil-water classification, so it has to expand the capacity and needs a larger oil storage tank.

[0003] For example, the Chinese patent with the patent name of a new type of accident oil tank, which is authorized and announced as CN217437820U, uses an overflow weir to automatically change the weir height by adjusting the weir plate, and the device for automatically changing the weir height is interlocked with the transformer oil discharge system. When the transformer discharges oil, the weir height is automatically lowered, and the accident oil is discharged into the main body of the accident oil tank through the overflow weir. In the non-oil discharge condition of the transformer, the overflow weir is in a high weir state, and the overflow weir blocks the rainwater entering the accident oil tank to prevent it from entering the main body of the accident oil tank. The rainwater is discharged through the rainwater discharge pipe arranged in the rainwater discharge part. This scheme can also handle the oil leakage accident of the substation well. Compared with the first prior art, this scheme can separate the oil and water in advance and store them separately, but it cannot be applied to the case of oil and water mixing. In summer, the peak season of electricity consumption is high, so the transformer failure is also high. However, this is also the peak season of the rainy season. For example, in the case of fire-fighting water and accident oil mixing emergency rescue, the oil and water are also mixed. Therefore, the deficiency of this prior art is that it lacks the use function required by the most important application scene, and technical improvement is needed. SUMMARY

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0026] EMBODIMENT

[0027] Please refer to Figure 1 , 36, the application provides the following technical scheme: a transformer substation multi-scene alarm emergency treatment system, comprising a control unit, a concrete base body 1, a cobblestone roadbed layer 2 arranged on the concrete base body 1, a clean water pool 16, an accident pool 14 and a heavy oil pool arranged below the cobblestone roadbed layer 2, a weir 1 15 arranged between the clean water pool 16 and the accident pool 14, a weir 2 11 arranged between the accident pool 14 and the heavy oil pool, a collection pool 22 arranged at the upper end of the clean water pool 16, a leakage hole 32 arranged at the lower end of the collection pool 22, a flow meter 31 and a concentration meter 30 arranged in the leakage hole 32, a flow guide valve 24 arranged at the lower end of the leakage hole 32, a hinge column 13 arranged at the side end of the flow guide valve 24, a hydraulic cylinder 1 arranged at the same side end of the hinge column 13 and the flow guide valve 24, an overflow pipe 21 arranged at the side of the flow guide valve 24 close to the weir 1 15, one section of the overflow pipe 21 being located in the flow guide valve 24 and the other section being located in the weir 1 15, a liquid level sensor 1 arranged at the side of the weir 1 15 close to the accident pool 14, an oil pumping pipe 1 7 arranged at the side of the weir 2 11 close to the accident pool 14, an oil unloading hole 3 arranged on the weir 2 11, and the flow guide valve 24 being capable of being opened or closed.

[0028] The working principle of the application is that the movable flow guide valve 24 arranged at the upper end of the emergency oil pool is used to distribute oil, water and oil-water mixture into different pools in advance, so as to reduce unnecessary oil-water mixing and then reduce the burden of oil-water separation; on this basis, in an extreme case, the clean water pool 16, the accident pool 14 and the heavy oil pool can be used in combination to indirectly expand the capacity and improve the emergency performance in the extreme case. It should be noted that the concentration meter 30 is mainly used to detect the concentration signal of oil, water and oil-water mixture to determine which one of the three, and of course other sensors or detectors in the prior art can also be used as long as they can have the same function. It should be noted that the flow meter 31, the concentration meter 30, the liquid level sensor and the piezoelectric switch and other signal source elements are electrically connected to the income end of the control unit PLC controller, and the electric control of the hydraulic cylinder 1, the electric control of the hydraulic cylinder 2 and the electromagnetic control elements such as the electromagnetic valve 34 are electrically connected to the control unit. The electric control system in the present scheme adopts the prior art, which will not be described here.

[0029] The workflow of the present application: Non-extreme case: When it is raining, the flow meter 31 and the concentration meter 30 detect the flow and concentration and transmit them to the control unit, and then determine that it is rainwater, at this time the flow valve 24 does not act, and the water in the flow valve 24 is directly discharged into the clean water pool 16 through the overflow pipe 21, without occupying the space of the accident pool 14, to prepare for the extreme case; when repairing or a single transformer leaks oil, similarly, it is determined that it is accident oil, at this time the hydraulic cylinder is contracted to drive the flow valve 24 to rotate clockwise and then stop, at this time the accident oil enters the heavy oil pool under the guidance of the flow valve 24, and when the flow meter 31 monitors the data to be zero, it is reset, and the flow valve 24 is reset under the driving force, it can be seen that it also does not occupy the space of the accident pool 14, to prepare for the extreme case; when the rain season and the transformer accident occur together, the flow valve 24 does not need to rotate, the middle of the flow valve 24 is opened, then the oil-water mixture can enter the accident pool 14, without the suspension plate 232 scheme, the oil flow can be placed in the heavy oil pool through overflow, for example, it can overflow through the oil discharge hole 3. The water in the accident pool 14 can be directly pumped out by the water pump 29, and the upper liquid level sensor 27 and the lower liquid level sensor 28 are used as the trigger signal for starting and stopping the water pump 29.

[0030] Reference Figures 2-6On the basis of the above scheme, the inventor optimizes the scheme to cope with extreme cases: specifically, remove the upper liquid level sensor 27 and the lower liquid level sensor 28, and use a non-overflow method to remove the oil in the accident pool 14 and an overflow method to remove the water in the accident pool 14, at which time the delayer 23 is needed, and other changes are not made. More specifically, a delayer 23 is provided in the accident pool 14, the delayer 23 includes a floating plate 232, the floating plate 232 is provided with an oil passing hole 233, the lower end of the floating plate 232 is provided with an air bag 231, the weir 15 is provided with a piezoelectric switch 19 used in cooperation with the floating plate 232, the air bag 231 injects gas to make the floating plate 232 between the oil layer and the water layer, the floating plate 232 is located above the water layer and is integrated with the oil layer, and the lower end of the oil pump 7 is close to the upper end surface of the floating plate 232 when the floating plate 232 triggers the piezoelectric switch 19. In extreme cases: the middle of the flow guide valve 24 is opened, the oil-water mixture enters the accident pool 14 through the leakage hole 32 and the opened flow guide valve 24, the liquid level rises and the floating plate 232 moves up, the floating plate 232 triggers the piezoelectric switch 19, and the lower end of the oil pump 7 is close to the upper end surface of the floating plate 232 at this time. At this time, the external oil pump connected thereto can remove the oil on the floating plate 232 to leave water. Since the floating plate 232 is suspended at the intersection of oil and water, the oil pump 7 removes oil, not water. In extreme cases, the liquid level continues to rise, no matter how high the liquid level rises, the upper end of the floating plate 232 is always oil, not water, which is determined by physical properties. In order to ensure that the floating plate 232 is suspended at the intersection of oil and water without being damaged by the impact of the oil-water mixture from the flow guide valve 24, the flow dividing plate 25 is fixed between the weir 15 and the weir 11, the flow dividing plate 25 divides the oil-water mixture into the wall perpendicular to the weir 15 and the weir 11, and enters the lower part of the accident pool 14 from the gap between the wall and the floating plate 232. Preferably, the flow dividing plate 25 is provided with wave-shaped stripes, which fully separate the oil and water in motion by using the different flow rates of oil and water.

[0031] In order to further improve the emergency, the water tank 16 and the accident pool 14 are connected by a drain channel, and the drain channel is provided with an electromagnetic valve 34, and the lower end of the oil suction pipe 7 is provided with a piezoelectric switch 36. When the piezoelectric switch 36 is triggered, the electromagnetic valve 34 is opened. At this time, when the electromagnetic valve 34 is opened, the water at the lower end of the floating plate 232 enters the water tank 16 through the drain channel and is finally discharged from the drain pipe 18 of the water tank 16. The oil in the accident pool 14 continuously overflows onto the upper end of the floating plate 232 and is sucked away from the oil suction pipe 7 or into the heavy oil pool to prolong the processing time and ensure safety. Further, when the emergency treatment is completed, the electromagnetic valve 34 in the drain channel is in an open state, and the water continues to be drained. The floating plate 232 moves downward until it triggers the piezoelectric switch 35 arranged at the lower part of the weir 15. When the piezoelectric switch 35 is triggered, the electromagnetic valve 34 is closed. The installation position of the piezoelectric switch 35 needs to be higher than the drain channel to ensure the safety water level and avoid excessive drainage of the floating plate 232 below the drain channel so that the oil above the floating plate 232 enters the drain channel. In summary, the piezoelectric switch 36 and the piezoelectric switch 35 are triggered by the floating plate 232 at the appropriate time, which opens the connection between the water tank 16 and the accident pool 14 and realizes continuous drainage and oil removal, so that the water tank 16, the accident pool 14 and the heavy oil pool are used in linkage and integration to improve the emergency performance in extreme conditions.

[0032] The diversion valve 24 in the above scheme is preferably the diversion valve 24 designed in the present application, specifically: the diversion valve 24 comprises an arc plate one 241, an arc plate two 243, two end rotating connections on the arc plate one 241 and the arc plate two 243 and a plurality of single-sided superimposable movable plates 247, the arc plate one 241 and the arc plate two 243 are respectively provided with a support plate one 242 and a support plate two 2411 at both ends, the arc plate two 243 is provided with a sliding rail 249 at the upper end, the sliding rail 249 is slidably connected with a sliding plate 248, the sliding plate 248 is provided with a groove 246, the groove 246 is provided with a roller column 245, the roller column 245 is vertically connected with a connecting plate 244, the connecting plate 244 is fixedly connected to the end of each movable plate 247, the end of the sliding plate 248 is rotatably connected with a hydraulic cylinder two 2410, the other end of the hydraulic cylinder two 2410 is hingedly fixed, the arc plate one 241, the arc plate two 243 and the support plate one 242 are all fixedly connected with a flow stopping plate 2412, and the support plate one 242 is further provided with a drainage plate. The diversion valve 24 of the present application integrates the functions of overflow temporary storage solution, diversion and direct discharge of liquid in one design and application, which is unique and ingenious. It fits the main application scenarios of the emergency pool and is applied to the clean water pool 16, the accident pool 14 and the heavy oil pool, so that the three oil pools can be used separately in extreme cases, and the three can be used together. In the initial state, because the diversion valve 24 has a certain curvature, the middle is sealed by the single-sided superimposable movable plate 247, which can contain the solution and fits the overflow discharge of clean water; the middle is sealed by the single-sided superimposable movable plate 247, which fits the diversion function through the rotation of the whole, and finally guides the oil into the heavy oil pool; the sliding plate 248 is driven by the hydraulic cylinder two 2410, the roller column 245 on the connecting plate 244 moves in the groove 246, forcing the movable plate 247 to rotate and then opening the diversion valve 24 to directly discharge the oil-water mixture into the accident pool 14, fitting the direct discharge needs in extreme cases. In addition, the ingenious part of this design is to fully apply the actual situation and layout, i.e. direct discharge in the accident pool 14, a small amount of water remaining in the diversion valve 24 during overflow function can be directly discharged into the accident pool 14 by opening and closing the movable plate 247 once, without affecting other functions, and the arc structure and containment of the diversion valve 24 also give the response time of the flow meter 31 and the concentration meter 30 detecting the material source of water, oil or oil-water mixture. In summary, the diversion valve 24 of the present application integrates the functions of overflow temporary storage solution, diversion and direct discharge of liquid in one design and application, which is indeed different from the existing oil pool design.

[0033] Further, in order to better realize the function of the flow guide valve 24, the flow guide valve 24 is provided with a sealing device 26 at one end penetrating through the weir two 11 and located at the oil discharging hole 3. This design is used for: first, preventing water or water-oil mixture from entering the heavy oil pool and causing unnecessary trouble; second, containing more solution to meet the liquid level requirement when overflow water. The sealing device 26 can be implemented according to the following scheme: the sealing device 26 comprises an n-shaped plate 261, a strip plate 262 fixed in the middle of the n-shaped plate 261, a plurality of parallel sliding columns 263 sleeved on the strip plate 262, a flexible strip 264 fixedly installed at the lower part of the sliding column 263, a spring seat 267 provided at the upper part of the sliding column 263, a limiting step 266 provided at the upper part of the strip plate 262, a reset element 265 provided between the n-shaped plate 261 and the sliding column 263, and a avoiding groove 268 provided at both ends of the n-shaped plate 261, wherein a sealing strip (not shown in the figure) is fixedly connected in the avoiding groove 268. The working principle is that in the initial state, the flow stopping plate 2412 is sealed by the sealing strip in the avoiding groove 268, and the flow guide plate is in close contact with the flexible strip 264 to form a solution cavity together with the flow stopping plate 2412. Due to the existence of the sealing strip and the flexible strip 264, the sealing property is good, which can prevent water or water-oil mixture from entering the heavy oil pool, and can also contain more solution to meet the liquid level requirement when overflow water. In addition, it should be noted that the rear edge of the sealing strip is designed with a plurality of sliding columns 263, which are matched with the reset element 265 such as spring. On the one hand, the flexible strip 264 can have a predetermined pressure for pressing the flexible strip 264 against the flow guide plate. On the other hand, the plurality of sliding columns 263 are arranged at intervals to support the flexible strip 264 and prevent it from excessive deformation, so that the structure stability is not lost and the sealing property is not lost.

[0034] Further, the heavy oil pool is provided with a weir three 4, the weir three 4 is connected with a filter 8, a liquid level sensor two 33 is arranged on one side of the weir two 11 close to the weir three 4, and an oil pumping pipe two 6 is arranged in the oil pool on one side of the weir three 4. The filter 8 can be fixed on the weir three 4 by interference fit. Since the oil from the flow guide valve 24 enters the primary oil pool 10, and the oil pumping pipe two 6 is arranged in the clean oil pool 9, the oil from the flow guide valve 24 is finally conveyed to the circulating system or storage tank and the like through the clean oil pool 9 under the action of the oil pumping pressure of the oil pumping pipe two 6 and the liquid level difference between the two oil pools.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or replace some technical features with equivalent ones. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
