1269010 (45)偵測到集水槽有水，而進行修護。另正壓式儲油（40b)容 器，如有破損，槽内漏出的油（0)會浮於水面，更容易偵測 到。是故，本實施例特別適用於加油站之儲油裝置，不僅利用 水池的水（w)來隔離外洩的油品（0)與基礎土壤接觸，不會污 染環境土壤地下水，並以水（w)來承載儲油容器（40b)及内部 油品（0)的部份重力。 是以，前揭幾種儲油容器（40)、（40a)、（40b)在樣態上 雖略有差異，但其安置於水中的儲油方法及主要裝置的特徵 皆相同，且可依不同油品及儲油需求，達到預期以水來隔離 油品與基礎土壤的接觸，或以水來承載儲油容器及油品的重 力，以及利用水來動態平衡儲油容器的側壓力。 綜上所述，本發明所揭示之方法及技術手段，確具「新穎 性」、「進步性」及「可供產業利用」等發明專利要件，祈請鈞 局惠賜專利，以勵發明，無任德感。 惟，上述所揭露之圖式、說明，僅為本發明之較佳實施例， 大凡熟悉此項技藝人士，依本案精神範疇所作之修飾或等效 變化，仍應包括本案申請專利範圍内。 1269010 【圖式簡單說明】 第一圖係本發明之實施流程方塊圖。 第二圖（A)〜（F)係本發明儲油裝置之一較佳實施例結 構剖示圖，其中第二圖（A)〜（C)係揭示該油品注入時之動態 平衡示意圖，第二圖（D)〜（F)係揭示該油品抽出時之動態平 衡示意圖。 第三圖（A)〜（F)係本發明儲油裝置中之儲油容器另一 可行實施例圖，其中第三圖（A)〜（C)係揭示該油品注入時之 動態平衡示意圖，第三圖（D)〜（F)係揭示該油品抽出時之動 態平衡示意圖。 第四圖係本發明儲油裝置中之儲油容器又一可行實施 例圖。 【主要元件符號說明】 (10)基礎土壤 (20) 壁面 (21) 蓋體 (30) 水池 (31) 底壁 (40) 、（40a)、（40b)儲油容器 (41) 油品入/出口 (41a)輸入管 (41b)輸出管 (41c)通氣管 (42) 流通口 ⑤ -13- 1269010 (43) 基架 (43’)基座組 (44) 集水槽 (45) 檢測器 (50) 備用水槽 (51) 連通管 (52) 自動給水裝置 (w)水 (0)油品1269010 IX. Description of the invention: [Technical field to which the invention pertains] The invention relates to an oil storage method and device disposed in water, which is to store an oil storage container in a pool, and the principle that the specific gravity of the oil is less than water is to separate the oil with water. Contact with the foundation soil, water to carry the oil container and the gravity of the oil and the use of water to dynamically balance the side pressure of the oil storage container. [Prior Art] • According to the traditional oil storage tank, it is divided into a ground oil storage tank and an underground oil storage tank. The straight medium oil storage tank must be on a solid base. The building can load a large capacity oil and the weight of the closed cylindrical steel tank is stable. The structural basis of the deformation. The traditional oil storage tank adopts the steel plate to withstand the side pressure of the oil storage, and its capacity has a certain limit, and the capacity increases with a large increase in the relative cost. For safety considerations, it must also be surrounded by the storage tank. The protective wall of all oil capacity is used to receive the leaked oil when the oil storage tank is damaged. However, if a natural disaster or t is destroyed, the oil will flow around, causing an uncontrollable catastrophe. Take Liuguang • (° Petrochemical) as an example, its crude oil storage tank has a capacity of 130,000 cubic meters (currently the largest oil storage tank in the Tai area). The oil storage tank has a diameter of about 86 meters and a height of about 24 2 feet. The steel (four) degree design is difficult to withstand the oil dust force of 24 meters deep, and the number of earthquake resistance above: *Including the base period Chu construction oil storage tank construction period requires:,. The cost is about NT$200 million. Due to the natural environment, rain and sun, must be, raw, rust, and then anti-rust paint, such as leakage, must be vented oil storage, month 'sequential' to exclude oil and gas can be welded. Traditional storage costs are high, and maintenance and repair costs are considerable. , search, sub-press, underground oil storage tank buried in the underground oil storage tank must be protected against corrosion 5 -5- s s1269010 covered, costly, if there is leakage, difficult to detect, can not be repaired, easy to cause environmental soil groundwater pollution. The present inventors have identified the lack of a conventional oil storage tank, and actively studied and improved to solve the above problems, which is the main subject of the present case. SUMMARY OF THE INVENTION It is an object of the present invention to provide an oil storage method disposed in water, which is to store an oil storage container in a pool, and to use oil to separate the oil from the foundation. The contact of the soil, the water to carry the gravity of the oil storage container and the oil, and the use of water to dynamically balance the side pressure of the oil storage container, and the water in the reserve water tank to adjust to maintain a certain water level in the pool, so the oil storage can be greatly reduced The pressure of the container. Another object of the present invention is to provide an oil storage method disposed in water, wherein the oil storage container is placed in the pool, the oil and the base soil are separated by water, and the groundwater of the environment is not polluted, and the oil storage container is leaked. The leaking oil will float out of the water and can be detected without visual inspection. In order to achieve the above object, the oil storage method of the present invention is carried out in the following steps: mad) forming a wall around the foundation soil to construct a pool; b) placing an oil storage container of a predetermined shape and volume in the pool And the bottom of the oil storage container is arranged to be in a state of being circulated and not flowing with the pool; c) maintaining a predetermined volume of water in the pool, surrounding the oil container, and depending on the oil Injecting or withdrawing the water level automatically; and d) loading the oil to be stored into the oil storage container and placing the oil in the storage tank 5 -6 - 1269010 no more than the internal volume of the oil storage container The specific gravity of the product is less than the physical properties of the water, the water in the pool is used to isolate the contact of the oil with the basic soil, or the gravity of the oil storage container and its oil, and the water is used to dynamically balance the oil storage container. Side pressure. [Embodiment] First, please refer to the first figure, which is a block diagram showing the steps of the implementation of the present invention, and please refer to the cross-sectional view of the embodiment of the second figure (A), the main implementation steps of the present invention and The equipment consists of: a). Forming a wall (2〇) around the foundation soil (1〇) to construct a pool (30), which is referred to herein as the base soil (1 〇), which is formed after the general base is dug down. The surface is sorrowful, and the wall (20) formed around the foundation soil (10) includes a continuous wall formed by reinforced concrete or grouting, etc. as a protective layer for the foundation soil (10). And isolation layer. b). Next, an oil storage container (4〇) of a predetermined shape and volume is disposed in the water tank (30); the oil storage container (40) comprises a metal plate, a reinforced concrete, a plastic... In the present embodiment, the oil storage container (4〇), there is no oil inlet/outlet (41), and the bottom surface thereof is directly disposed on the bottom wall (31) of the pool, the pool The bottom or the bottom of the wall is provided with at least one flow port (42), so that the inside of the residual oil container (40) and the pool (30) are in a permeable state. This is a preferred embodiment of the present invention, but is not limited thereto, that is, The interior of the oil storage container (4〇) may also be in a non-circulating state with the water tank (30), which will be further described in detail later. c) • Maintain a predetermined volume of water (w) in the above-mentioned pool (30). The term “water” as used herein includes fresh water, sea water or industrial wastewater. Since the pool (30) is provided with a wall (20), it is injected. The water (w) is basically less likely to penetrate into the base soil -7-1269010 (10), so the loss is not much, and the water (w) referred to herein as "maintaining the predetermined capacity" means that the water level is based on the storage. The state of the oil container (40) and the volume of the oil therein are adjusted at any time, that is, the water tank (30) is provided with a water level adjustment and an automatic water supply device, which will be described later. d). Inject the oil (0) to be stored into the oil storage container (40), where the oil (0) includes petroleum crude oil and its pyrolysis oil, mineral oil, animal oil, vegetable oil, chemicals, etc. a liquid product having a specific gravity of less than 1; as a result, the amount of oil injected into the oil product (w) is not greater than the internal volume of the oil storage container (40), because in the present embodiment, the oil storage container ( 40) There is a circulation port (42) between the system and the pool (30). If the injected oil is larger than the internal volume of the oil storage container (40), the flow port (42) flows out and penetrates into the pool (30). Finally, it will float on the water. Therefore, as shown in the second figure (B), (C), when the oil (0) is injected into the oil storage container (40) from the oil inlet/outlet (41), due to the oil (0) The specific gravity is generally around 0.9, so it is less than the specific gravity of water (w) 1, so the oil (0) will float above the water (w), and the water (w) inside the oil storage container (40) will follow the oil ( The increase of 0) gradually flows out of the flow port (42). Since the volume of the pool (30) is constant, when the oil amount of the oil (w) increases and the storage space of the water (w) decreases, the water level rises. In order to make the excess water (w) can be stored and reused, a feasible embodiment of the present invention is provided with a standby water tank (50) around the pool (30), and the standby water tank (50) is close to the tank. The height of the surface is provided with a connecting pipe (51) in communication with the water tank (30). When the water level of the water pool (30) reaches the upper limit, the communication hole (51) can overflow into the standby water tank (50). Store and reuse. Please refer to the second figure (D) ~ (F), which is a schematic diagram showing the extraction of the oil (0) in the oil storage container (40). When the oil (0) is gradually reduced, the oil storage 5 -8- 1269010 The water level of the container _ part of the water (w) will gradually increase by buoyancy to push the oil (9) up, and the storage capacity! The external water is placed in the water tank (w) and gradually decreases due to the inflow into the container. At this time, the water stored in the standby water tank (10) can be introduced into the water tank (30), and can be provided on the (four) water tank (10). - automatic water supply device (4), the automatic water supply device (52) may include a conventional component such as a suction pump, a water level detector, etc., when the water level in the pool_ reaches the lower limit, the water of the standby water tank (50) is automatically drawn. In the pool (10)), the function of the Xiaoxiang water supports the gravity of the oil storage container (10) while dynamically balancing the oil storage container (4_side pressure. According to one of the above embodiments, the oil storage method and equipment of the present invention are The proportion of the oil used is less than the physical property of the water, and the pool (3_water (w) is used to isolate/contact the base soil by the mouth (0), and is used to carry the oil storage container (40) and its interior The gravity of the oil (0), and the side pressure of the oil storage container (40) is dynamically balanced by the water. A specific data is illustrated, for example, the oil storage tank (40) installed in the pool (3〇) ), when the depth is 24 feet high, the oil (w) with a specific gravity of 〇.9 is stored, and the oil in the oil storage container The liquid level will be about 2.4 meters higher than the water level of the pool (3〇), so the water (w) of the pool (30) carries and offsets the pressure of 9〇%, and the oil storage container (4〇) only Withstand 10% of the pressure, so the material strength design of the oil storage container (4 〇) is as long as the storage pressure of 2·4 meters deep, instead of the storage pressure of 24 meters deep. In the case of oil (0), the water (w) of the pool (3 承受) withstands and offsets the pressure by 99%, and the oil storage container (4 〇) only withstands about 1% of the pressure, so the woman of the present invention is placed in the water. The oil storage equipment completely breaks the traditional concept of building oil storage tanks (tanks) with thick steel plates in the south. For example, reinforced concrete is used as the material, and the same capacity as the six light is 130,000 cubic meters (24 meters high) The oil storage tank with a diameter of 86 meters only needs to be 24 meters high, and the length and width of each 76 meters can be -9-1269010 (saving the base area of 10 meters Χίο meters). So just in the pool (30 The steel bar is placed inside, the formwork on the frame, grouting, etc., and the template is removed after the cement is hardened. If the plastic plate or stainless steel sheet is constructed, the speed is fast. Since the invention is to place the oil storage container (40) in the pool (30), it is not necessary to construct a protective wall under the ground level, and the oil product is not caused by accidental earthquake or human damage. (0) Circumfluent and endangering the plant area. Moreover, the oil storage container (40) is placed under the ground, is not subject to human damage, and does not need to be equipped with lightning rods, and the oil storage equipment can be greened or used twice; The equipment is built under the ground and has minimal impact on the environment and climate, which can reduce the vaporization of oil. The water (w) of the pool (30) has the function of offsetting the earthquake during the earthquake, reducing the earthquake damage. In addition, because the pressure of the oil storage container is low, The overall equipment cost can be reduced. According to the foregoing oil storage method disposed in the water of the present invention, the container for storing oil, another feasible embodiment is as shown in the third figure (Α)~(F), and has the same structure. In the previous embodiment, the same figure is used. In this embodiment, the oil storage container (40a) has an oil inlet/outlet (41) thereon, and there is no flow port at the bottom, and a plurality of base frames are used. 43) Located in the pool 30) The bottom wall (31) forms a water flow passage at the bottom of the oil storage container (40a), but the internal oil and the pool (30) are in a non-circulating state; thus, when the oil (0) is injected into the oil storage container (40a) At the same time, using the pre-release method and the automatic water supply device (52), simultaneously injecting water (w) into the pool (30) to make the oil (0) level in the oil storage container (40a) and the pool (30) The water level rises synchronously, please refer to the third figure (A) ~ (C). Further, as shown in the third diagrams (D) to (F), when the oil (0) is withdrawn from the oil storage container (40a), the water (w) is simultaneously withdrawn from the water tank (30) to make the oil storage container (40a). The liquid level of the inner oil (0) drops synchronously with the water level of the pool (30), and the pressure of the oil storage tank is dynamically balanced by the water level of the pool (30). 1269010 The present invention can be applied to a small oil storage tank in addition to the large oil storage container disclosed above, and is used in an oil storage tank (container) of a gas station; please refer to the fourth figure, which discloses another feasible method of the present invention. The embodiment is the same as the previous embodiment, and is represented by the same figure. In this embodiment, the oil storage container (40b) is provided with a bottomless state, and an oil inlet/outlet is also provided thereon ( 41) to the cover body (21) above the pool, except that it comprises an input pipe (41a) and an output pipe (41b), and a vent pipe (41c) with a pressure valve is provided outside the pool (30). The implementation steps a). and b) are the same as the foregoing embodiments and will not be described again. The implementation step c) is also substantially the same as the previous embodiment, except that the water level of the pool (30) covers more than the oil storage container (40b), that is, the oil storage container (40b) is always immersed in In the water (w) of the pool (30), the final implementation step d) is also substantially identical to the previous embodiment. As for the apparatus, in the embodiment, a cover body (21) is provided on the pool (30), and the oil storage container (40b) is fixed on a base group (43'), and the base group (43, It can be a single large base set, or a base set (43') composed of a plurality of bases as shown in the fourth figure, the purpose and requirement of which the oil storage container (40b) is secured in the pool (30) Without floating or shaking. Further, the preferred arrangement of the oil storage container (40b) is fixed at an oblique angle to the relatively inclined base group (43'), and further includes a sump at the lower surface. (44) The sump (44) is coupled to an external detector (45). Further, the oil storage container (40b) is provided with both a negative pressure type and a positive pressure type. Wherein, if the negative pressure type oil storage container is damaged, and the pool water penetrates into the container, the water (w) has a specific gravity greater than the oil (0), and the infiltrated water is concentrated on the bottom of the oil storage container (40b), and The sink (44) in the lower part is concentrated, and it is easy to detect the water in the sump by the external detector -11 - 1269010 (45). In addition, if the positive pressure type oil storage (40b) container is damaged, the oil (0) leaking from the tank will float on the water surface and be more easily detected. Therefore, this embodiment is particularly suitable for the oil storage device of a gas station, which not only uses the water (w) of the pool to isolate the leaked oil (0) from contact with the foundation soil, does not pollute the environmental soil groundwater, and uses water ( w) to carry part of the gravity of the oil storage container (40b) and the internal oil (0). Therefore, although several oil storage containers (40), (40a), and (40b) are slightly different in appearance, the oil storage methods and main devices disposed in the water have the same characteristics and can be Different oil products and oil storage requirements are expected to use water to isolate the contact between the oil and the foundation soil, or to carry the gravity of the oil storage container and the oil with water, and to use water to dynamically balance the side pressure of the oil storage container.
