Description

Technical Field

[0001] The utility model relates to the technical field of aviation fuel storage tanks, in particular to an aviation fuel storage tank interface sinking detection and adjustment device. Background Art

[0002] As the cornerstone of aviation development, safe and reliable storage of aviation fuel is essential to ensure aviation operations. Aviation kerosene is usually stored in well-designed steel vertical metal cone-bottom tanks. These tanks are not only large in size and heavy in weight, but also responsible for storing a large amount of fuel, and are a key link in the aviation fuel supply chain. However, in actual use, tank subsidence not only occurs frequently, but also may cause serious safety hazards.

[0003] The sinking of storage tanks is mainly due to uneven settlement of the foundation or structural deformation caused by long-term load-bearing. This sinking will directly affect the position and structural integrity of the tank discharge pipe. Since there is usually a fixed supporting structure at the bottom of the discharge pipe, the sinking of the storage tank may cause the discharge pipe to fail to sink synchronously, and then cause stress concentration, deformation, and even weld tearing at the connection between the discharge pipe and the storage tank, causing fuel leakage. This leakage will not only pollute the environment, but may also cause serious accidents such as fires, resulting in casualties and huge economic losses.

[0004] To solve this problem, the measures currently taken by aviation fuel companies are mainly regular manual monitoring and maintenance to evaluate the status of storage tanks and discharge pipes, and to promptly detect and deal with sinking problems. However, this method not only consumes a lot of manpower, material and financial resources, but is also inefficient, difficult to achieve real-time monitoring and early warning, and poses a major safety hazard.

[0005] Therefore, inventing a device that can automatically detect and adjust the sinking of the tank interface can not only monitor the status of the tank in real time, prevent and reduce the risk of fuel leakage, but also significantly improve the safety and economic benefits of aviation fuel storage. It has important practical significance and broad application prospects for the aviation fuel industry. Utility Model Content

[0013] a pressure sensor disposed on an upper surface of the top bracket; and

[0014] The push rod is connected with the inner rotating body to drive the inner rotating body to rotate.

[0015] Compared with the previous technology, the beneficial effects of the utility model are:

[0016] 1.

DETAILED DESCRIPTION

[0025] The utility model is described in detail below in conjunction with the accompanying drawings, but the protection content of the utility model is not limited to the following:

[0026] like Figure 1-5 As shown, a sinking detection and adjustment device for the interface of an aviation fuel storage tank, the main body of which is a sinking detection device 1, which is installed below a discharge pipe 3 provided on a storage tank 2 of aviation fuel;

[0027] The sinking detection device 1 comprises:

[0028] A limiting sleeve 11 is fixed to the ground, and a thrust bearing 12 is provided at the bottom of the limiting sleeve 11;

[0029] An inner rotating body 13, the lower part of which is placed in the limiting sleeve 11, and the bottom surface of the inner rotating body 13 contacts the top surface of the thrust bearing 12, and the upper surface of the inner rotating body 13 is provided with a thread structure 18;

[0030] The threaded sleeve 14 is sleeved on the upper part of the inner rotating body 13 and is threadably matched with the inner rotating body 13;

[0031] The top bracket 15 is fixedly connected to the top of the threaded sleeve 14 and is used to support the discharge pipe 3;

[0032] a pressure sensor 16 disposed on the upper surface of the top bracket 15; and

[0033] The push rod 17 is connected to the inner rotating body 13 to drive the inner rotating body 13 to rotate.

[0034] The inner rotating body 13 is provided with a through hole penetrating through the side wall of the inner rotating body 13 , and the pushing rod 17 is inserted into the through hole.

[0035] The utility model utilizes a rotatable inner rotating body to cooperate with a threaded sleeve, so that the rotation of the inner rotating body can gradually make the threaded sleeve rise or sink relative to the storage tank, thereby reducing the impact of the sinking of the storage tank on the discharge pipe and other pipes connected thereto, thereby reducing and preventing possible losses. Here, the inner rotating body 13 can be driven to move up and down by the rotation of the inner rotating body because the top bracket 15 is limited by the discharge pipe so that it cannot rotate coaxially with the inner rotating body.

[0036] It should be noted that the limiting sleeve 11 can be provided with a base, and the base is provided with screw holes, through which the limiting sleeve (11) is fixed to the ground.

[0037] The thrust bearing 12 is a ball bearing;

[0038] The ball bearing includes an upper bearing 121, a lower bearing 122, and a plurality of balls 123 embedded between the upper bearing 121 and the lower bearing 122;

[0039] The upper bearing 121 is fixedly connected to the bottom surface of the inner rotating body 13 ; the lower bearing 122 is fixedly connected to the bottom surface of the limiting sleeve 11 .

[0040] The thrust bearing can convert the vertical force of the tank sinking into horizontal rotational force, making the rotation of the inner swivel faster and more convenient.

[0041] The top bracket 15 is an arc-shaped structure that is close to the surface of the discharge pipe 3. The arc-shaped structure is closer to the cylindrical structure of most pipelines and can better receive the pipeline.

[0042] A rubber gasket is provided on the upper surface of the top bracket 15, and a pressure sensor 16 is embedded in the rubber gasket. The rubber gasket can protect the structure of the pressure sensor.

[0043] The pressure sensor 16 is a wireless pressure sensor. The wireless pressure sensor can be wirelessly connected to the computer and transmit pressure data in real time. When the pressure data is abnormal, an early warning is issued. The staff can control the position of the inner rotating body according to the early warning and the abnormal change of the value. That is, if the pressure is too high, it means that the tank body is sinking, and it is necessary to reduce the overall height of the utility model to reduce the pressure of the synchronously sinking connecting pipe on the pressure sensor.

[0044] Furthermore, the data of the wireless pressure sensor can also be transmitted to portable devices such as mobile phones, smart watches or smart bracelets through computer programs to realize the early warning function.

[0045] Usage: stack the utility model under the discharge pipe of the storage tank or under the pipe connected thereto, and then connect the wireless pressure sensor to the computer for use.

[0046] Although the utility model uses specific embodiments and their alternatives to illustrate and describe the utility model, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit and scope of the utility model. Therefore, it should be understood that except for the limitations of the attached claims and their equivalents, the utility model is not limited in any sense.
