Description
Technical Field
[0001] This utility model relates to the field of fuel tanks, and in particular to a fuel tank insulation layer fixing structure. Background Technology
[0002] Fuel tanks are an indispensable core component of spacecraft, aircraft, and other high-performance transportation vehicles. Their main function is to store and protect fuel. The design of fuel tanks must be able to withstand extreme working environments to ensure the stability and safety of fuel, especially in high-temperature, low-temperature, and high-pressure environments. With the continuous development of aerospace and aviation technologies, the design and manufacturing of fuel tanks face increasingly higher requirements, especially in terms of temperature control, structural strength, and safety.
[0003] Existing technologies, such as the utility model patent with publication number CN223104680U, disclose a methanol engine fuel tank. This patent includes a fuel tank body and a mounting plate located at the upper end of the fuel tank body. The mounting plate has at least two rings of evenly distributed circumferential strip-shaped through holes. Sliding elements are slidably mounted within these through holes, and vibrating rods extending to the bottom surface of the fuel tank body are fixedly mounted through these sliding elements. An ultrasonic generator for driving multiple vibrating rods to vibrate at high frequency is fixedly mounted through the center of the mounting plate. A transmission element connects the top of the ultrasonic generator to the top of the vibrating rods. The top of the ultrasonic generator also has a first drive mechanism for driving multiple vibrating rods to move radially along the mounting plate. This fuel tank, by incorporating vibrating rods and an ultrasonic generator, uses the high-frequency vibration of the vibrating rods to maintain the methanol fuel in a uniformly mixed state, preventing sedimentation and stratification, promoting natural circulation of the methanol fuel within the tank, and maintaining fuel homogeneity.
[0004] In the prior art, since fuel tanks are usually exposed to the external environment, when the external temperature is too high, the fuel temperature inside the fuel tank is also likely to be too high. Excessive fuel temperature can cause fuel instability, especially for liquid fuels. When the temperature is too high, liquid fuels are prone to evaporation or vaporization, which causes the gas pressure to rise rapidly, thereby increasing the pressure load on the fuel tank and even causing safety hazards such as leakage or explosion. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that in the existing technology, since fuel tanks are usually exposed to the external environment, when the external temperature is too high, the fuel temperature inside the fuel tank is easily too high. When the fuel temperature is too high, it will cause fuel instability, especially liquid fuel. When the temperature is too high, liquid fuel is easy to evaporate or vaporize, causing the gas pressure to rise rapidly, thereby increasing the pressure load on the fuel tank, and even causing safety hazards such as leakage or explosion. Therefore, a fuel tank insulation layer fixing structure is proposed.
[0006] To solve the above-mentioned technical problems, this utility model provides a fuel tank insulation layer fixing structure, including: a fuel tank body, an adjustment structure provided on the arc surface of the fuel tank body, the adjustment structure including a plurality of fixing rods, the plurality of fixing rods being fixedly connected to the fuel tank body, the arc surfaces of the plurality of fixing rods being slidably connected to the same auxiliary plate, a plurality of connecting blocks being slidably connected to both sides of the auxiliary plate, the plurality of connecting blocks being grouped in sets of four, a common heat insulation plate being fixedly connected to one side of a group of connecting blocks, and a plurality of connecting frames being fixedly connected to the arc surface of one of the heat insulation plates, the inner walls of the connecting frames being rotatably connected.

[0008] Preferably, a soft pad, which is a rubber pad, is fixedly connected to one side of the mounting plate.

[0012] Preferably, the arc surface of the connecting plate is provided with anti-slip texture, and the anti-slip texture is evenly distributed on the connecting plate.
[0013] The effect achieved by the above components is that the anti-slip texture increases the friction of the connecting plate, preventing the operator's hands from slipping when rotating the connecting plate.
[0014] Preferably, a guide block is fixedly connected to one side of the fixing block.
[0015] The effect achieved by the above components is that, due to the small size of the guide block, the fixing block can be better inserted into the connecting groove.
[0016] Preferably, the arc surface of the auxiliary rod is fitted with two coil springs, and the two ends of the coil springs are fixedly connected to the positioning block and the connecting frame, respectively.
[0017] The effect achieved by the above components is that the coil spring can increase the torsional force of the positioning block, making the positioning block more convenient to rotate.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0023] Please see Figures 1 to 4 The present invention provides a fuel tank insulation layer fixing structure, comprising: a fuel tank body 1, wherein the arc surface of the fuel tank body 1 is provided with an adjustment structure 2.
[0024] In the embodiments of this utility model, please refer to Figures 2 to 4The adjustment structure 2 includes several fixed rods 201, which are fixedly connected to the fuel tank body 1. The arc surfaces of the fixed rods 201 are slidably connected to the same auxiliary plate 202. Several connecting blocks 203 are slidably connected to both sides of the auxiliary plate 202. The connecting blocks 203 are grouped in sets of four. One side of each group of connecting blocks 203 is fixedly connected to the same heat insulation plate 204. The arc surface of one heat insulation plate 204 is fixedly connected to several connecting frames 205. An auxiliary rod 206 is rotatably connected to the inner wall of the connecting frame 205. A positioning block 207 is fixedly connected to the arc surface of the auxiliary rod 206. One side of the positioning block 207 is fixedly connected to... A mounting plate 208 is attached, with a connecting groove 221 on one side. Several auxiliary frames 209 are fixedly connected to the arc surface of another heat insulation plate 204. A connecting frame 210 is fixedly connected to one side of each auxiliary frame 209. A screw 211 is threadedly connected to the inner wall of the connecting frame 210. A connecting plate 212 is rotatably connected to one end of the screw 211. A fixing block 213 is fixedly connected to one side of the connecting plate 212. The fixing block 213 and the auxiliary frame 209 are slidably connected. Two limiting rods 214 are slidably connected to the inner wall of the connecting frame 210. The limiting rods 214 are fixedly connected to the connecting plate 212. A connecting disc 215 is fixedly connected to the other end of the screw 211. By setting the adjustment structure 2, the heat insulation plate 204 can be easily fixed to the fuel tank body 1, effectively isolating the external high-temperature environment, preventing drastic fluctuations in the internal fuel temperature, maintaining the fuel's stable state, and thus ensuring fuel stability. A soft pad 218 is fixedly connected to one side of the mounting plate 208. The soft pad 218 is a rubber pad. Due to the elasticity of the soft pad 218, the mounting plate 208 can be more firmly placed within the auxiliary frame 209. An auxiliary hole 219 is provided on the arc surface of the mounting plate 208, which allows personnel to easily rotate the mounting plate 208, achieving the effect of convenient control of the mounting plate 208. The arc surface of the connecting plate 215 is provided with anti-slip texture. 216. Anti-slip texture 216 is evenly distributed on the connecting plate 215. The anti-slip texture 216 can increase the friction of the connecting plate 215 and prevent the personnel from slipping their hands when rotating the connecting plate 215. A guide block 217 is fixedly connected to one side of the fixing block 213. Since the guide block 217 is small in size, the fixing block 213 can be better inserted into the connecting groove 221. Two coil springs 220 are sleeved on the arc surface of the auxiliary rod 206. The two ends of the coil springs 220 are fixedly connected to the positioning block 207 and the connecting frame 205 respectively. The coil springs 220 can increase the torsional force of the positioning block 207, making the positioning block 207 more convenient to rotate. The working principle of the fuel tank insulation layer fixing structure provided by this utility model is as follows: By setting the adjustment structure 2, the auxiliary plate 202 is first moved and inserted into the fixing rod 201 of the fuel tank body 1. Then, the heat insulation plate 204 is rotated to drive the connecting block 203 to rotate inside the auxiliary plate 202, so that the two heat insulation plates 204 are in contact with the fuel tank body 1. Then, the mounting plate 208 is rotated using the auxiliary hole 219, so that the mounting plate 208 drives the positioning block 207 to rotate. The positioning block 207 then drives the auxiliary rod 206 to rotate inside the connecting frame 205 until the mounting plate 208 is inserted into the auxiliary frame 209. Then, the connecting plate 215 is rotated with the help of the anti-slip texture 216, so that the connecting plate 215 drives the screw 211 to rotate inside the connecting frame 210. While the screw 211 is rotating, it also drives the connecting plate 212 to move. The connecting plate 212 also drives the limiting rod 214 to move inside the connecting frame 210. While the connecting plate 212 is moving, it also drives the fixing block 213 to move inside the auxiliary frame 209 until the fixing block 213 is inserted into the connecting groove 221 of the mounting plate 208. At this time, the heat insulation plate 204 is fixed to the fuel tank body 1. The soft pad 218 is elastic, which makes the mounting plate 208 more secure in the auxiliary frame 209. The anti-slip texture 216 can increase the friction of the connecting plate 215 and prevent the personnel from slipping their hands when rotating the connecting plate 215. The guide block 217 is small in size, which allows the fixing block 213 to be better inserted into the connecting groove 221. The coil spring 220 can increase the torsional force of the positioning block 207, making the positioning block 207 more convenient to rotate.
