Description

Technical Field

[0001] This utility model relates to the field of emergency oil tank drainage technology, specifically to an emergency oil tank in a booster station. Background Technology

[0002] Existing substations typically house multiple large transformers, with the total oil content reaching hundreds of tons. When equipment with high oil content, such as the main transformer, malfunctions, undergoes maintenance, catches fire, or explodes, oil leaks occur, flowing through drain pipes to an emergency oil storage tank. Simultaneously, when the fire sprinkler system is activated, a large amount of water-oil mixture enters the pipeline and flows into the emergency oil storage tank. Due to the large volume of the oil-water mixture, its flow velocity in the drain pipe is extremely high, usually in a jet state. The oil-water mixture entering the emergency oil tank is in a floating state, making it difficult to quickly separate the water and oil. This necessitates increasing the capacity of the emergency oil tank, thereby increasing its footprint and construction costs. Furthermore, since continuous water spraying is required during accident handling, the spray volume is difficult to determine. When the volume of the oil-water mixture is large, a fixed-volume emergency oil tank cannot guarantee that all the oil-water mixture will be stored within it, easily leading to leakage and environmental pollution.

[0003] Utility model patent CN219928582U discloses an emergency oil tank for a booster station, comprising an oil inlet pipe, a diversion well, a daily oil distribution tank, and an emergency oil storage tank. One end of the oil inlet pipe extends into the diversion well. The daily oil distribution tank is fixedly connected to the right side of the diversion well, and the emergency oil storage tank is fixedly connected to the lower side of the diversion well. A water intake pipe is connected to the top of the emergency oil storage tank, and an oil delivery pipe is connected to the bottom of the diversion well. The oil delivery pipe extends into the daily oil distribution tank, and a water outlet is connected to the right side of the daily oil distribution tank. The top of the water outlet is lower than the bottom of the oil delivery pipe. The bottom of the diversion well is connected to the emergency oil storage tank, and the top of the daily oil distribution tank is connected to... The system has a first sludge removal port, and a second sludge removal port is connected to the top of the emergency oil storage tank. A first monitoring and oil sampling mechanism is installed in the first sludge removal port, and a second monitoring and oil sampling mechanism is installed in the second sludge removal port. A certain amount of water is pre-stored in the daily oil separation tank, ensuring the water level is flush with the bottom of the outlet. During daily use, the oil-water mixture flows through the inlet pipe into the diversion well. After being diverted by the diversion well, the smaller, slower-flowing portion of the daily oil-water mixture flows from the oil delivery pipe into the daily oil separation tank. In the daily oil separation tank, the oil-water mixture is separated; the separated water flows from the outlet into the sewage pipe, and the separated oil is stored in the daily oil separation tank. Inside the oil separator, staff can monitor the daily oil level using the first monitoring and sampling mechanism. When the oil level is nearly full, the oil is extracted and recycled using this mechanism. In the event of an accident, leaked oil from the transformer mixes with water sprayed from the fire sprinkler, forming an oil-water mixture that flows through the inlet pipe into the diversion well. After being diverted by the well, the large volume and high flow rate of the oil-water mixture flow into the accident storage tank for storage. Once the mixture has settled and separated, staff can recover the oil using the second monitoring and sampling mechanism, and then drain the wastewater from the accident storage tank through the water intake pipe. The oil tank is emptied by removing the oil, thus preparing for the next accident. This invention enables the separation of oil-water mixtures during daily use to discharge wastewater, and the storage of oil-water mixtures during accidents. It also facilitates monitoring of oil volume and recovery of oil. In this patent, the oil-water mixture that leaks during daily use can be collected and the water discharged. It can also collect and store oil-water mixtures during accidents. However, the volume of the accident oil tank is fixed, and the amount of oil-water mixture collected is fixed. During the collection process, the oil and water are mixed. As the amount of oil-water mixture increases, excess oil-water mixture is prone to leakage and pollution. Utility Model Content

[0004] The main purpose of this utility model is to provide an emergency oil pool for booster stations, which solves the problem that existing emergency oil pools have a fixed volume and are difficult to separate oil and water during the collection of oil-water mixtures, resulting in leakage of the oil-water mixture.

[0005] To achieve the above objectives, this utility model provides an emergency oil sump for a booster station, comprising:

[0006] A collection assembly includes a collection pool and partition walls spaced apart within the collection pool.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] In one embodiment, see Figure 1 , 2 The present invention relates to an emergency oil pool for a booster station, comprising a collection component and a drainage component.

[0023] The collection assembly includes a collection pool 1 and partition walls 2 spaced apart within the collection pool 1, dividing the collection pool 1 into multiple adjacent collection sub-pools 3. The collection pool 1 is equipped with a guide pipe 4, and the guide pipe 4 has multiple component dispensing pipes 5 each facing the various collection sub-pools 3. Dispensing pipes 5 are equipped with dispensing valves 6. Flow stabilizing plates 7 are spaced apart and staggered within the collection sub-pools 3. Each collection sub-pool 3 is equipped with a liquid level monitoring element 8 and an alarm element 9. The bottom surface of each collection sub-pool 3 has a recessed sealing groove 10. The density of the liquid level monitoring element 8 is less than that of oil and water. The density and liquid level monitoring element 8 move upward under the pressure of the liquid level in the collection sub-pool 3, so that the alarm element 9 is connected to issue an alarm; the drainage assembly includes a drain pipe 11 and a water level monitoring element 12 installed in the collection sub-pool 3. One end of the drain pipe 11 is located inside the sealing groove 10 and is lower than the bottom surface of the collection sub-pool 3, and the other end is located outside the collection sub-pool 3 and is lower than the bottom surface of the collection sub-pool 3. A drain valve 13 is provided on the drain pipe 11; the density of the water level monitoring element 12 is greater than the density of the oil but less than the density of the water, and the bottom end of the water level monitoring element 12 is close to the bottom end of the collection sub-pool 3.

[0024] Preferably, the collection pool 1 is a hollow rectangular structure with one end open, which can be made of reinforced concrete. The partition wall 2 is set along the long side of the collection pool 1 and is made of reinforced concrete.

[0025] Preferably, the guide pipe 4 is set along the long side of the collection tank 1. One end of the guide pipe 4 is connected to the drainage pipe of the booster station to collect the oil-water mixture discharged from the booster station. The other end is closed or connected to one of the collection sub-tanks 3. The number of liquid distribution pipes 5 is the same as the number of collection sub-tanks 3. The liquid distribution pipes 5 are located at the bottom of the collection sub-tank 3.

[0026] Further, see Figure 2 , 4 The collection sub-pool 3 is provided with a cover plate 14, and the cover plate 14 is provided with a sliding hole 15; the liquid level monitoring component 8 includes a sliding rod 801 with the perforated sliding hole 15 located in the collection sub-pool 3, and a liquid panel 802 provided on the sliding rod 801. The liquid panel 802 is located in the collection sub-pool 3, and a floatation bladder 803 is provided on the liquid panel 802; the alarm component 9 includes a support plate 901 provided on the cover plate 14, and an alarm light 902 provided on the support plate 901. The support plate 901 is located directly above the sliding hole 15, and a pressure switch 903 is provided on the support plate 901.

[0027] Preferably, the cover plate 14 is made of reinforced concrete.

[0028] Preferably, the end face of the liquid panel 802 away from the slide bar 801 is provided with a groove, and the float bladder 803 is located in the groove.

[0029] Preferably, the support plate 901 is "L" shaped, with the long side of the support plate 901 integrally cast with the cover plate 14, the short side of the support plate 901 located directly above the sliding hole 15, and the pressure switch 903 located at the short side of the support plate 901.

[0030] Preferably, the alarm light 902 has a built-in battery, and the pressure switch 903 is installed on the connecting wire between the alarm light 902 and the battery.

[0031] In the above setup, after the oil-water mixture enters the guide pipe 4 through the drain pipe, the separating valves 6 on the collection sub-pool 3 can be opened in batches. For example, two separating valves 6 can be opened simultaneously to collect the oil-water mixture. As the volume of the oil-water mixture in the collection sub-pool 3 increases, the surface of the oil-water mixture rises, and the height of the float bladder 803 rises accordingly, thereby driving the slide bar 801 to move upward. When the slide bar 801 abuts against the pressure switch 903, the float bladder 803 is close to the top of the collection sub-pool 3. At this moment, the liquid level of the oil-water mixture in the collection sub-pool 3 is close to the top of the collection sub-pool 3. At the same time, the pressure switch 903 is activated after being subjected to force, thereby energizing the alarm light 902 through the battery, reminding the staff to close the separating valve 6 on the collection sub-pool 3, and simultaneously open the separating valves 6 on the other collection sub-pool 3 that has not collected the oil-water mixture, thus using the collection sub-pool 3 in batches to collect the oil-water mixture. When the collection sub-pool 3 that has been filled first does not have any new oil-water mixture entering, it begins to enter the oil-water stratification state.

[0032] Further, see Figure 2 The flow stabilizer 7 is set along the length of the partition wall 2, and the flow stabilizer 7 is set on both sides and in the middle of the collection tank 3; the outlet direction of the liquid separator 5 is directly opposite the flow stabilizer 7.

[0033] Preferably, the flow stabilizer 7 is made of reinforced concrete, and the outlet direction of the liquid distribution pipe 5 is directly opposite the flow stabilizer 7 located in the middle of the collection tank 3.

[0034] Further, see Figure 3 The bottom of the sealing groove 10 is a wedge-shaped structure with one end higher and the other end lower. The sealing groove 10 is filled with sealing liquid 16. The sealing groove 10 is located at the end away from the liquid distribution pipe 5. One end of the drain pipe 11 is close to the middle of the bottom end of the sealing groove 10.

[0035] Preferably, the sealing groove 10 is elongated, and the bottom end of the sealing groove 10 is lower than the bottom end of the collecting sub-groove.

[0036] Preferably, the sealing fluid 16 is water.

[0037] In the above configuration, the oil-water mixture entering the collection sub-tank through the separator 5 has a flow rate and enters the collection sub-pool 3 in a jet shape, impacting the flow stabilizing plate 7 located in the middle of the collection sub-pool 3. The flow stabilizing plate 7 weakens the potential energy of the oil-water mixture, thereby reducing the flow rate of the oil-water mixture. Under the action of multiple sets of flow stabilizing plates 7, the flow rate of the oil-water mixture entering the collection sub-tank is slowed down, which facilitates the acceleration of the stratification of the oil-water mixture.

[0038] Further, see Figure 4 The drain pipe 11 is inverted "U" shaped, and a liquid filling pipe 17 is provided on the drain pipe 11. A liquid filling valve 18 is provided on the liquid filling pipe 17.

[0039] Preferably, the liquid inlet pipe 17 is located in the middle of the liquid outlet pipe 11.

[0040] Further, see Figure 4 The cover plate 14 is provided with a through hole 19; the water surface monitoring component 12 includes a support rod 1201 disposed in the through hole 19 and a float 1202 disposed on the support rod 1201; the cover plate 14 is provided with an alarm light 20 and a touch switch 21; the end of the support rod 1201 located outside the through hole 19 is provided with a touch plate 22.

[0041] Preferably, the float 1202 is made of rubber, and the support rod 1201 is provided with a support plate 901, and the float 1202 is installed on the support plate 901.

[0042] Preferably, a battery is provided between the warning light 20 and the pressure switch 21.

[0043] In the above setup, when there is no oil-water mixture in the collection sub-pool 3, the support rod 1201 and the float 1202 move downwards into the collection sub-pool 3, with the float 1202 near the bottom of the collection sub-pool 3. The pressure plate 22 presses down the pressure switch 21, and the warning light 20 illuminates. When the oil-water mixture enters the collection sub-pool 3 and separates into layers, the density of the float 1202 is less than the density of water but greater than the density of oil, causing the float 1202 to be located at the stratification point between the oil and water. As the water level in the stratified water in the collection sub-pool 3 rises, the float 1202 rises accordingly, the support rod 1201 and the pressure plate 22 move upwards, and the pressure plate 22 separates from the pressure switch 21. Warning light 20 goes out; after the oil-water mixture in collection tank 3 has been left to stand for a predetermined time, water can be added to the liquid addition pipe 17. The water flows into the drain pipe 11 to expel the air in the drain pipe 11, and the liquid addition valve 18 is closed and the drain valve 13 is opened. The drain pipe 11 uses siphon to draw out the water located in the lower layer of collection tank 3. As the water decreases, the float 1202 moves down, causing the support plate 901 to press the touch switch 21, and the warning light 20 lights up, reminding the staff to close the drain valve 13 to prevent the oil from being discharged along with it; at this time, the water in collection tank 3 is discharged, the liquid level in collection tank 3 drops, and the oil-water mixture can be collected again.

[0044] In this embodiment, the oil-water mixture is collected in different time periods by the liquid distribution pipe 5 and the oil level monitoring device 8 monitors the oil-water mixture volume in the collection sub-pools 3, which facilitates the control of the collection in different collection sub-pools 3. The collection sub-pools 3 that are full of oil-water mixture can be allowed to stand and separate into layers first. Under the action of the flow stabilizing plate 7, the oil-water mixture can be allowed to stand still quickly, which facilitates the separation of oil and water. The remaining empty collection sub-pools 3 can collect oil-water mixture at the same time to ensure that the oil-water mixture does not overflow. The water that has separated into layers flows out through the drain pipe 11 and the amount of water discharged is controlled by the water level monitoring device 12 to prevent the oil from being discharged along with it. The internal storage space of the collection sub-pools 3 that have discharged some water becomes larger, and the oil-water mixture can be collected again, thereby maximizing the use of the collection sub-pools 3 to collect oil-water mixture and realizing the separation of oil-water mixture while collecting it.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
