[0002] Fuel tank leak detection is an important step to ensure good sealing of the fuel tank and prevent oil leakage. There are many methods for fuel tank leak detection, such as the simplest visual inspection method: it is to directly visually inspect the outside of the fuel tank, especially the welds and interfaces. This method is laborious and prone to missed detection. There is also an ultrasonic detection method: it is to emit ultrasonic waves into the fuel tank, and then judge whether there is a leak through the reflected waves in the fuel tank. This method has high sensitivity and high accuracy, but it requires professional equipment and technology, and the cost is high. For this reason, a leak detection system for a rack fuel tank is proposed to solve the above technical problems. Utility Model Content

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] One of the preferred embodiments of the present application is as follows: Figures 1 to 4 As shown, a leak detection system for a rack oil tank comprises an oil tank body 1 (rack oil tank), a water tank 2 and a water delivery module 3. The water delivery module 3 is installed on the water tank 2 and cooperates with the oil tank body 1.

[0025] It should be known that there is clean water in the water tank 2; and when the side leakage of the oil tank body 1 is detected, the water in the water tank 2 is transported to the oil tank body 1 through the water delivery module 3, for example, the height of the oil tank body 1 is about 80% of the oil tank, and then the outside of the oil tank body 1 is observed in a visual manner. If there is water leakage, it means that this is the leakage point; if there is no water leakage, it means that the sealing of the oil tank body 1 is good; and after the leak detection is completed, the water in the oil tank body 1 is pumped back through the water delivery module 3, that is, returned to the water tank 2 to complete the detection process, and the pumped back water can be used next time.

[0026] It should be noted that, although this method is somewhat similar to the visual inspection method in the prior art, the time and details required for the specific observation of the two are different. For the prior art, it is to observe the welds and interfaces on the outside of the fuel tank body 1, and for the rack fuel tank, there may be some obstructions that make it difficult to see the parts, which greatly increases the time required for the inspection and reduces the efficiency of the inspection. The present application is mainly aimed at whether there is water seepage on the outside of the fuel tank body 1, that is, it only needs to observe whether there are water marks on the outside of the fuel tank body 1, or whether there are water stains on the ground, so as to quickly judge the sealing of the fuel tank body 1.

[0027] It can be seen that the leak detection system used in the present application for detecting the sealing of the fuel tank has a simple structure, can quickly detect the sealing of the fuel tank body 1, and the water after the detection can be recycled for the next detection, which is environmentally friendly and pollution-free. This detection system not only improves work efficiency, but also effectively reduces resource waste and environmental impact, making the detection of fuel tank sealing more convenient and environmentally friendly.

[0028] One of the embodiments of the present application is as follows: Figure 2 As shown, the water delivery module 3 includes a pump body 301 (water pump) and a pair of water pipes 302. The water pipes 302 are correspondingly installed at the input end and the output end of the pump body 301, and the water pipes 302 are respectively connected to the oil tank body 1 and the water tank 2.

[0029] It can be understood that when leak detection is performed, the water pipe 302 connected to the input end of the pump body 301 is connected to the water tank 2, and the water pipe 302 connected to the output end of the pump body 301 is connected to the oil tank body 1. At this time, the pump body 301 can extract the water in the water tank 2 and transport it to the oil tank body 1, thereby performing leak detection on the oil tank body 1.

[0030] When the leak detection is completed, the two water pipes 302 connected to the pump body 301 can be swapped, that is, the water pipe 302 connected to the input end of the pump body 301 is connected to the oil tank body 1, and the water pipe 302 connected to the output end of the pump body 301 is connected to the water tank 2. At this time, the pump body 301 can pump back the water in the oil tank body 1 and transport it to the water tank 2, thereby completing the water recycling after the leak detection.

[0031] Based on the above embodiment, another embodiment of the present application is as follows: Figure 2 As shown, the water delivery module 3 is preferably used in a pair. It should be noted that when one water delivery module 3 is used, the two water pipes 302 connected to the pump body 301 need to be swapped during the leak detection process, which makes the operation process cumbersome. When a pair of water delivery modules 3 are used, one of the water delivery modules 3 is used to form a water outlet for pumping water from the water tank 2, and the other water delivery module 3 is used to form a water return end for returning water to the water tank 2.

[0032] It should be known that if Figure 2 As shown, one of the water delivery modules 3 is responsible for pumping the water in the water tank 2 into the oil tank body 1, while the other water delivery module 3 is responsible for pumping the water in the oil tank body 1 back into the water tank 2. The two are independent of each other, which can simplify the operation of leak detection of the oil tank body 1 and greatly improve the detection efficiency.

[0033] In this embodiment, Figure 2 and Figure 4As shown, in order to ensure the cleanliness of the water in the water tank 2 and prevent impurities in the water tank 2 from entering the oil tank body 1, thereby facilitating the subsequent recycling of water, a filter 9 can be provided at the port where the water pipe 302 and the water tank 2 cooperate to filter impurities in the water. This can prevent impurities in the water from entering the oil tank body 1, thereby ensuring the accuracy of the detection; at the same time, it can also prevent impurities contained in the oil tank body 1 from entering the water tank 2 and causing pollution, thereby ensuring the cleanliness of the water, which can be recycled.

[0034] Further, in order to improve the portability of the water pipe 302 connection, as Figure 2 and Figure 3 As shown, the water pipe 302 can be matched with the water tank 2 at the port where it is connected by a quick connector 7, so that the staff can easily remove and reinstall the water pipe 302. This design not only improves the operability of the water tank 2, but also reduces the workload of the staff during installation and maintenance. The quick connector 7 can also effectively prevent the water pipe 302 from leaking during the connection process, ensuring the stability and reliability of the water circulation system.

[0035] In this embodiment, in order to facilitate the injection of clean water into the water tank 2, a water inlet may be provided at the top of the water tank 2. Of course, a filter 6 (such as a filter screen) is also required at the water inlet, so that the clean water entering can filter impurities in the water under the action of the filter 6, thereby ensuring the cleanliness of the water in the water tank 2. Of course, the filter 6 can filter larger impurities entering the water, and the filter 9 can filter fine impurities in the water, thereby ensuring the cleanliness of the water entering the oil tank body 1.

[0036] Furthermore, in order to facilitate cleaning of the water tank 2, a detachable sealing cover 5 can be provided at the top position of the water tank 2. For example, the sealing cover 5 can be installed at the opening of the water tank 2 by means of buckles or bolts so that it can be easily opened when cleaning. Of course, the above-mentioned return water end and water inlet can be provided on the sealing cover 5. Because after water enters the water tank 2 from the return water end or the water inlet, the water in the water tank 2 will not flow back from the return water end and the water inlet under the action of gravity, thereby ensuring that the water in the water tank 2 will not overflow.

[0037] In addition, a drain port may be provided at the lower end or bottom of the water tank 2, and a drain valve 8 may be provided at the drain port to facilitate the regular discharge of water in the water tank 2 after multiple uses, so as to keep the water tank 2 clean. It should be noted that during the sealing test, the water in the water tank 2 is filtered before use, and no other substances are added during use, that is, the water in the water tank 2 becomes waste water after multiple uses, and this waste water is also pollution-free and can be directly discharged into the underground pipeline, that is, no special filtering and treatment are required, making the leak detection system more environmentally friendly.

[0038] One of the embodiments of the present application is as follows: Figure 2 As shown, a liquid level display component 4 for monitoring the liquid level of the water tank 2 is provided; and the liquid level display component 4 has various structural forms, including but not limited to the following two:

[0039] Structure 1 (such as Figure 3 As shown): the liquid level display assembly 4 includes a liquid level tube 401, that is, the liquid level tube 401 is installed at the side position of the water tank 2, and the height change of the liquid in the liquid level tube 401 is used to display the height of the liquid in the water tank 2.

[0040] Structure 2: The liquid level display component 4 includes a liquid level meter (liquid level sensor) and a display screen. The liquid level meter is installed in the water tank 2, and the display screen is installed on the outside of the water tank 2 and electrically connected to the liquid level meter. The liquid level in the water tank 2 is measured by the liquid level meter, and then the data is transmitted to the display screen for display, so that the user can know the liquid level in the water tank 2 at any time.

[0041] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
