Description

Technical Field

[0001] The utility model relates to the technical field of oil storage tanks, in particular to an explosion-proof oil storage tank. Background Art

[0002] An oil storage tank is a large container specifically used for storing liquid oil products, which is widely used in industries such as petroleum, chemical engineering, and energy. The oil storage tank is usually made of metal, with certain corrosion resistance and sealing performance, which can effectively prevent oil leakage and external pollution.

[0003] For example, the Chinese utility model patent disclosed with the publication number CN219949295U: An explosion-proof oil storage tank. In this application, a set of protection plates is arranged below the tank body, and support plates are arranged outside the protection plates for support. At the same time, a telescopic plate is arranged and telescoped through the support plate. And a base is arranged below the protection plate, and buckle rings are arranged at both ends of the base for easy bundling during transportation. First of all, when the existing oil storage tank is transported by a special vehicle, the tank body of the oil storage tank is fixedly connected to the vehicle as a whole, and there is no unreasonable use of cotton or hemp ropes for bundling. And in this application, the protection and transportation components are used to limit the tank body from both sides, which can only limit the movement of both sides of the tank body. However, when the vehicle is in transportation, there will be sudden acceleration and sudden braking situations, which will cause the tank body to displace to the unconstrained sides. At the same time, for the same and common oil storage tanks as this application, when in use, if during transportation or storage, since the oil storage tank is usually made of steel plate materials welded together, although it has certain strength and toughness, under strong external impact, stress concentration may occur in the welds or the plates themselves, resulting in local rupture, which will lead to the leakage of the stored fuel inside. And when the rupture occurs instantaneously, a large amount of oil in the tank will leak out and quickly mix with the air to form a combustible gas cloud. Moreover, the impact may generate sparks or high temperatures, providing an ignition source for these combustible gases. Once the sufficient concentration and temperature conditions are reached, the combustible gas cloud will explode and release huge energy, causing serious damage and threat to the surrounding environment. Summary of the Utility Model

The anti-collision mechanism is composed of a plurality of anti-collision plates, a first mounting frame, a second mounting frame, a mounting shaft and other components, which can effectively prevent the inner tank filled with fuel from being broken by external impact. At the same time, a puncture-proof net is arranged between a plurality of partition plates close to the inner side of the outer tank body, which can buffer and intercept the objects that pierce the outer tank body, thereby further reducing the risk of the inner tank being broken, and further preventing the occurrence of deflagration due to fuel leakage.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figures 1 - 5As shown in the figure, the explosion-proof oil storage tank provided by the utility model includes an outer tank body 1. A plurality of supports 2 are fixedly installed at the bottom of the outer tank body 1. A plurality of support columns 3 are fixedly installed at the bottom of the supports 2. A manhole 4 and a breather valve 5 are respectively fixedly installed at the top of the outer tank body 1. An inner tank 6 is fixedly installed inside the outer tank body 1. Anti-collision mechanisms 7 are arranged on both sides of the plurality of supports 2. The anti-collision mechanism 7 includes an anti-collision plate 8, a first mounting bracket 9 and a second mounting bracket 10. The first mounting bracket 9 is movably installed between the two second mounting brackets 10 through two first mounting brackets 9. The second mounting bracket 10 is movably installed on one side of the corresponding support 2 through a mounting shaft 11.

[0023] As Figure 2 shown, a plurality of partition plates 12 are fixedly connected between the outer tank body 1 and the inner tank 6. A stab-proof net 13 is fixedly connected between the plurality of partition plates 12. And the stab-proof net 13 is close to the inner side of the outer tank body 1. By installing an outer tank body 1 outside the inner tank 6 through a plurality of partition plates 12, it can play a role in strengthening the protection of the inner tank 6. The setting of the stab-proof net 13 can prevent external objects from piercing the inner tank 6 due to impact, playing a role in double protection for the outer tank body 1;

[0024] As Figures 3 - 5 shown, a limit block 14 is fixedly installed at one end of the mounting shaft 11. A fixing block 15 is fixedly installed at the other end of the mounting shaft 11. And the mounting shaft 11 is inserted and installed in a through hole on one side of the support 2. A first slot 16 is opened on one side of the second mounting bracket 10. The second mounting bracket 10 is inserted and installed on the fixing block 15 on one side of the corresponding mounting shaft 11 through the first slot 16 and fixed by screws. A compression spring 21 is also sleeved on the mounting shaft 11 between the second mounting bracket 10 and the support 2. By means of the setting of the mounting shaft 11, the second mounting bracket 10 can be movably installed on one side of the corresponding support 2, and the compression spring 21 can play a role in buffering the force on the second mounting bracket 10. A plug frame 17 is fixedly installed on one side of the first mounting bracket 9. A fixing seat 18 is fixedly installed on the side of the first mounting bracket 9 opposite to the plug frame 17. A plurality of reinforcing ribs 19 are fixedly installed on one side of the anti-collision plate 8. Second slots 20 are opened on both sides of the anti-collision plate 8 relative to the two first mounting brackets 9. The anti-collision plate 8 is inserted and installed on the fixing seats 18 on one side of the two first mounting brackets 9 through the second slots 20 on both sides. And the two first mounting brackets 9 are respectively inserted and installed on one side of the corresponding second mounting bracket 10 through the plug frames 17 on one side. By means of the setting of the anti-collision plate 8, the first mounting bracket 9 and the second mounting bracket 10, the outer tank body 1 and the inner tank 6 can be further protected from external impact, so as to prevent fuel leakage and explosion due to the impact on the lower part of the outer tank body 1 and the inner tank 6 that is vulnerable to impact.

[0025] It should be noted that the present utility model is an explosion-proof oil storage tank. When the lower layer position on the outer side of the outer tank body 1 that is prone to being impacted is impacted, it can move towards the outer tank body 1 through the impact-resistant plate 8 or the second mounting bracket 10 that is impacted. Moreover, the second mounting bracket 10 drives the mounting shaft 11 to move in the through hole on one side of the support 2, and makes the second mounting bracket 10 compress the compression spring 21 on the outer side of the mounting shaft 11 towards the support 2. Thus, through the cooperation of the impact-resistant plate 8, the first mounting bracket 9, the second mounting bracket 10, the mounting shaft 11, and the compression spring 21, the impact force received is buffered, thereby protecting the outer tank body 1 from impact. When impacted by a large impact force on the outer side of the outer tank body 1, it is through the secondary impact resistance of the multiple partition plates 12 connected between the outer tank body 1 and the inner tank 6. And when a sharp object pierces the outer tank body 1 and stabs towards the inner tank 6, the metal anti-stabbing net 13 installed on the inner side of the outer tank body 1 can buffer the stabbed object. Thus, the design of the mesh is dense and firm, which can effectively intercept and disperse the impact force of the sharp object, making it unable to penetrate the mesh surface, and can effectively prevent the explosion caused by the rupture of the inner tank 6 resulting in fuel leakage.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
