Description

Technical Field

[0001] This utility model relates to the field of double-walled oil tanks, and more specifically, to a double-walled oil tank with leak detection. Background Technology

[0002] In the energy storage sector, the safety and environmental friendliness of oil tanks are paramount. Traditional single-layer oil tanks, due to their simple structure, are susceptible to soil corrosion and external impacts over long-term use, leading to tank rupture and oil leaks. This can cause environmental problems such as soil and groundwater pollution, and may also result in fires and explosions due to leaked flammable fuels. With increasingly stringent environmental regulations and growing safety awareness, single-layer oil tanks are no longer sufficient to meet current needs.

[0003] Chinese utility model patent CN219468649U discloses a double-walled oil tank with leak detection function. In use, when a side leak occurs during normal operation, the leaking oil flows down the outer wall of the tank into the detection plate, and finally drips through the drain hole onto the top of the collection plate. The increased weight on the collection plate causes the sliding rod to slide downwards along the inner wall of the first sliding hole, while the return spring contracts, causing the collection plate to press down and activate the detection button. This triggers a flashing warning light to alert personnel, improving the safety of the oil tank. However, in rainy or snowy weather, rainwater can easily enter the collection plate through the drain hole, causing the detection button to misread.

[0004] Therefore, it is necessary to redesign a double-walled oil tank with leak detection to address the above-mentioned problems. Utility Model Content

[0023] 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.

[0024] Reference Figure 1-5 A double-walled oil tank with leak detection includes a protective box 1 and an oil tank 2. Multiple alarm devices 13 are symmetrically fixedly installed on the inner bottom wall of the protective box 1. A detection device is provided on the inner bottom wall of the protective box 1, and the output end of the detection device is in contact with the multiple alarm devices 13. The outer wall of the oil tank 2 is fixedly installed on the upper surface of the protective box 1 by a fixing plate 3. A one-way pipe 14 is fixedly connected to the bottom of the oil tank 2. Multiple lifting rings 4 are fixedly installed circumferentially on the outer wall of the oil tank 2. A manhole 5 is provided at the top of the oil tank 2.

[0025] The detection device includes a spring 12, which is fixedly installed on the inner bottom wall of the protective box 1. One end of the spring 12 is fixedly installed with an oil receiving tray 9, and the bottom end of the oil receiving tray 9 is in contact with multiple alarm devices 13. An installation groove 11 is opened on the upper surface of the oil receiving tray 9, and an oil-absorbing sponge 10 is fixedly installed in the installation groove 11. The oil-absorbing sponge 10 has the ability to absorb oil and can quickly absorb leaked oil, preventing the oil from forming a flow layer in the oil receiving tray 9 and reducing the instability of the oil receiving tray 9 caused by oil shaking, which affects the accuracy of detection. In addition, the oil-absorbing sponge 10 can prevent oil from evaporating and reduce the safety hazards caused by oil and gas accumulation.

[0026] A fixing groove 8 is provided on the inner wall of the protective box 1. A sealing ring 7 is fixedly installed in the fixing groove 8. Multiple drainage holes 6 are provided on the inner wall of the fixing groove 8. The positions of the multiple drainage holes 6 are higher than the positions of the sealing ring 7. When a small amount of water seeps into the protective box 1 through the sealing ring 7, the accumulated water can be drained in time.

[0027] Multiple pre-embedded columns are symmetrically fixed at the bottom of the protective box 1, which can firmly fix the protective box 1 to the foundation, thereby enhancing the stability of the entire device.

[0028] When this invention is in use, if the oil tank 2 leaks, the oil drips through the one-way pipe 14 onto the oil-absorbing sponge 10 and is quickly absorbed. As the oil accumulates, the overall weight of the oil receiving tray 9 increases, compressing the spring 12 under gravity, causing the oil receiving tray 9 to move downwards. Because the bottom of the oil receiving tray 9 is in contact with multiple alarm devices 13, when the oil receiving tray 9 moves down to a certain extent, the alarm device 13 located below the oil receiving tray 9 is triggered. When the oil receiving tray 9 moves downwards due to the increased weight from absorbing the leaking oil, it receives a pressure signal from the oil receiving tray 9. According to a preset pressure threshold, once the received pressure exceeds the threshold, the alarm device 13 is activated and emits an alarm through sound and light to remind the staff that the oil tank 2 is leaking.

[0029] A sealing ring 7 is fixed in the fixing groove 8 on the inner wall of the protective box 1, which can effectively prevent external rainwater, mud, etc. from entering the interior of the protective box 1 and avoid interfering with the leak detection. At the same time, multiple drainage holes 6 are opened in the inner wall of the fixing groove 8, which are higher than the sealing ring 7. If a small amount of water seeps into the protective box 1, the water can be discharged through the drainage holes 6, keeping the interior of the protective box 1 dry and clean, and ensuring that the leak detection device can work in a reliable environment.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
