Description

Technical Field

[0001] This utility model relates to the field of petrochemical oil storage tank technology, specifically a petrochemical oil storage tank with protective function. Background Technology

[0002] Petrochemical storage tanks are large containers used in the petrochemical industry for the safe storage of crude oil, refined oil, liquefied petroleum gas (LPG), and other liquid chemical raw materials. Their core functions are to ensure the continuity of production processes, regulate the balance of material supply and demand, and reduce safety and environmental risks during storage and transportation. Based on their structural form, storage tanks are mainly divided into vertical cylindrical (such as floating roof tanks to reduce volatilization, and fixed roof tanks to adapt to heavy oil), horizontal (small-capacity pressure storage), and spherical (high-pressure LPG storage) types. They are mostly made of carbon steel, stainless steel, or composite materials and are equipped with safety auxiliary facilities such as breather valves, fire protection systems, and leak monitoring. The design must strictly comply with domestic and international standards such as API and GB, taking into account explosion-proof, fire-proof, leak-proof, and environmental protection requirements (such as VOCs recovery and double-wall anti-seepage). They are widely used in refineries, chemical plants, oil depots, and strategic reserves. With technological advancements, intelligent monitoring and green storage and transportation technologies are driving the upgrading of storage tanks towards high efficiency, safety, and low carbon emissions.

[0003] Based on existing petrochemical storage tank technologies, it has been found that existing petrochemical storage tanks pose leakage and safety risks. Leaks from these tanks can lead to petroleum products entering the environment, causing soil and groundwater pollution, and potentially triggering fires or explosions, threatening human health and ecological safety, while also causing huge economic losses. If lightning strikes the storage tank area, it can ignite petroleum product vapors, causing violent fires or explosions, which will not only cause serious damage to equipment and facilities, but may also endanger the lives of operators.

[0004] Based on this, the present invention designs a petrochemical oil storage tank with protective function to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a petrochemical oil storage tank with protective function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a petrochemical storage tank with protective function, comprising a petrochemical storage tank body, a protective mechanism provided on the outside of the petrochemical storage tank body, and a monitoring mechanism provided on the outside of the protective mechanism. The protective mechanism includes a first protective cover, a second protective cover, and a support base. A support base is provided below the petrochemical storage tank body. The first protective cover is provided at the left end of the support base, and the second protective cover is provided at the right end of the support base. Both the first and second protective covers are made of stainless steel. The monitoring mechanism includes a grounding wire and a grounding electrode. The grounding wire is fixedly connected to the right end of the second protective cover, and the grounding electrode is fixedly connected to the end of the grounding wire away from the second protective cover.

[0007] Optionally, the protective mechanism further includes a door body and a mounting groove. Both the first and second protective covers are equipped with door bodies, and the support base has a mounting groove in the middle.

[0008] Optionally, a docking plate is fixedly installed at one end of the first protective cover near the second protective cover, and docking grooves are provided at both the front and rear ends of the support base.

[0009] Optionally, a sealing gasket is provided inside the docking groove, and the sealing gasket is located between the docking groove and the first protective cover.

[0010] Optionally, a first mounting plate is fixedly installed at both the front and rear ends of the first protective cover, and a second mounting plate is provided below the first mounting plate. A first limiting bolt is installed on the second mounting plate and the first mounting plate.

[0011] Optionally, a third mounting plate is fixedly installed at both the front and rear ends of the second protective cover, and a fourth mounting plate is provided below the third mounting plate. A second limiting bolt is installed on the fourth mounting plate and the third mounting plate.

[0012] Optionally, the monitoring mechanism further includes a pressure monitor, a gas monitor, and an alarm light. A pressure monitor is fixedly installed on the upper end of the first protective cover, and a gas monitor is fixedly installed on the upper end of the second protective cover. Both the pressure monitor and the gas monitor are equipped with alarm lights.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model includes a protective mechanism that significantly enhances the safety of oil storage through multi-dimensional protection. First, the first and second protective covers are constructed of stainless steel to form a double-layered enclosure. The precise fit between the connecting plate and the connecting groove on the support base, combined with the sealing gasket, creates a sealed space that directly prevents leaked oil or volatile gases from spreading outwards, thus avoiding environmental pollution and fire hazards. Second, the detachable design of the protective covers (connected to the mounting plate via the first and second limiting bolts) facilitates maintenance and repair, and extends service life by replacing the sealing gasket. More importantly, the first and second protective covers form a continuous conductor based on the Faraday cage principle. In the event of a lightning strike, the current can be quickly conducted to the grounding electrode through the grounding wire, preventing charge accumulation from igniting the oil-gas mixture. Simultaneously, the high strength of the stainless steel material can withstand external fire or physical impact, further reducing the risk of explosion.

[0015] 2. This utility model includes a monitoring mechanism that manages leakage risks through an early warning system. Firstly, pressure and gas monitors are deployed on the top of the protective cover, forming a dual monitoring network for pressure fluctuations and oil / gas concentration within the confined space. When a leak occurs in the storage tank, the pressure monitor accurately detects an abnormal increase in internal pressure, while the gas monitor identifies changes in volatile organic compound concentration using a highly sensitive gas-sensitive element. The two work together to trigger an alarm light, emitting an audible and visual signal, ensuring that operators detect the danger immediately and activate the emergency plan. Secondly, the grounding system, consisting of a grounding wire and grounding electrode, not only provides a complete lightning discharge channel for the Faraday cage but also eliminates the risk of static electricity buildup, preventing small electric sparks from igniting flammable gases. Monitoring data can be transmitted in real-time through a control terminal, supporting remote monitoring and data analysis. Combined with the physical barrier function of the protective mechanism, a closed-loop protection chain of "leakage monitoring - environmental isolation - risk warning - emergency response" is formed, significantly reducing the possibility of environmental pollution, fire, explosion, and secondary disasters.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figures 1-9 In this embodiment of the present invention, a protective petrochemical storage tank includes a petrochemical storage tank body 1. A protective mechanism 2 is provided on the outside of the petrochemical storage tank body 1, and a monitoring mechanism 3 is provided on the outside of the protective mechanism 2. The protective mechanism 2 includes a first protective cover 201, a second protective cover 202, and a support base 204. The support base 204 is provided below the petrochemical storage tank body 1. The first protective cover 201 is provided at the left end of the support base 204, and the second protective cover 202 is provided at the right end of the support base 204. Both the first protective cover 201 and the second protective cover 202 are made of stainless steel. The protective mechanism 2 also includes a door body 203 and a mounting groove 205. The door body 203 is installed on both the first protective cover 201 and the second protective cover 202. The mounting groove 205 is provided in the middle of the support base 204. A docking plate 206 is fixedly installed at one end of the first protective cover 201 near the second protective cover 202. The front and rear ends of the support base 204 are provided with docking grooves 207. A sealing gasket 208 is provided inside the docking groove 207. The sealing gasket 208 is located between the docking groove 207 and the first protective cover 201. A first mounting plate 209 is fixedly installed at both the front and rear ends of the first protective cover 201. A second mounting plate 210 is provided below the first mounting plate 209. A first limiting bolt 211 is installed on the second mounting plate 210 and the first mounting plate 209. A third mounting plate 212 is fixedly installed at both the front and rear ends of the second protective cover 202. A fourth mounting plate 213 is provided below the third mounting plate 212. A second limiting bolt 214 is installed on the fourth mounting plate 213 and the third mounting plate 212.

[0030] See Figure 2 , Figure 3 , Figure 5 , Figure 6and Figure 7 Initially, during installation, it is only necessary to push the first protective cover 201 and the second protective cover 202 closer together to make them seal and connect, ensuring that the sealing gasket 208 is placed inside the docking groove 207. Then, adjust the multiple first limit bolts 211 and second limit bolts 214 to make the first protective cover 201 and the second protective cover 202 tightly installed on the support base 204, thereby realizing the installation operation of the protective mechanism 2. The protective mechanism 2 will become the protective compartment of the petrochemical oil storage tank 1.

[0031] Among them, the protective mechanism 2 adopts a wrap-around protective structure and uses the Faraday cage principle to create a brand-new protective chamber. The first protective cover 201 and the second protective cover 202 adopt a detachable structure and can be reused repeatedly. The protective mechanism 2 is an additional protective structure for the petrochemical oil storage tank 1. On the one hand, it can directly block the gas or liquid leaked from the petrochemical oil storage tank 1 and protect the petrochemical oil storage tank 1 from external factors, such as sunlight, rain and fire. On the other hand, the first protective cover 201 and the second protective cover 202 form a Faraday cage, which can effectively reduce the safety risk of lightning strikes and prevent fires caused by lightning strikes.

[0032] The monitoring mechanism 3 includes a grounding wire 301 and a grounding electrode 302. The grounding wire 301 is fixedly connected to the right end of the second protective cover 202. The grounding electrode 302 is fixedly connected to the end of the grounding wire 301 away from the second protective cover 202. The monitoring mechanism 3 also includes a pressure monitor 303, a gas monitor 304 and an alarm light 305. The pressure monitor 303 is fixedly installed on the upper end of the first protective cover 201 and the gas monitor 304 is fixedly installed on the upper end of the second protective cover 202. An alarm light 305 is installed on both the pressure monitor 303 and the gas monitor 304.

[0033] See Figure 3 Initially, the monitoring mechanism 3 is divided into a grounding structure and a monitoring structure. The grounding wire 301 and the grounding electrode 302 can be used to conduct static electricity and ensure that the Faraday cage of the protection mechanism 2 functions. The monitoring structure is equipped with a pressure monitor 303 and a gas monitor 304. Before activation, the pressure monitor 303 and the gas monitor 304 need to be powered on and connected to the control terminal. The pressure monitor 303 and the gas monitor 304 monitor the air environment inside the first protective cover 201 and the second protective cover 202. When the petrochemical oil storage tank 1 leaks, the pressure monitor 303 and the gas monitor 304 will detect changes in air pressure and gas distribution, respectively, so as to remind the user to quickly take emergency measures. Due to the addition of the first protective cover 201 and the second protective cover 202, even if the petrochemical oil storage tank 1 leaks, the first protective cover 201 and the second protective cover 202 will block the leaked gas or liquid immediately, achieving the effect of isolation and protection.

[0034] The working principle of this utility model is as follows: After the petrochemical oil storage tank 1 is stably installed by the support base 204, the operator pushes the first protective cover 201 and the second protective cover 202 along the docking groove 207 of the support base 204. The precise cooperation between the docking plate 206 and the docking groove 207 achieves a sealed connection. At this time, the sealing gasket 208 forms a double sealing layer on the contact surface between the protective cover and the support base 1, effectively blocking the exchange of substances between the external environment and the storage tank. Subsequently, the first limiting bolt 211 and the second limiting bolt 214 respectively lock the cooperation structure of the first mounting plate 209 and the second mounting plate 210, and the third mounting plate 212 and the fourth mounting plate 213, so that the stainless steel protective cover forms a complete Faraday cage structure. When struck by lightning, the conductivity of the protective cover guides the lightning current through the grounding wire 301 to the grounding electrode 302 buried underground. To prevent charge buildup from causing sparks, the pressure monitor 303 monitors the internal pressure changes of the protective cover in real time, while the gas monitor 304 detects the concentration of volatile organic compounds through a multi-sensor array. When a leak occurs in the storage tank, the leaking substance is physically blocked in the sealed space by the protective cover. At this time, the pressure monitor 303 detects an abnormal increase in internal pressure, and the gas monitor 304 simultaneously identifies that the oil and gas concentration exceeds the standard. Both emit audible and visual alarm signals through the alarm light 305. Personnel can quickly intervene through the door 203, and the mounting slot 205 provides an expansion interface for subsequent maintenance equipment. This device, through the physical isolation of the protective mechanism 2 and the electromagnetic shielding of the Faraday cage, combined with the real-time environmental perception of the monitoring mechanism 3, forms a full-process protection system of leak-monitoring-alarm-response, significantly reducing the risks of environmental pollution, fire and explosion, and lightning strikes.
