[0022] 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.
[0023] Example 1
[0024] Combination Figures 1-5 A leak-proof buried double-walled oil tank includes a ground groove 1, a double-walled oil tank body 3 connected inside the ground groove 1 via a disassembly and assembly mechanism 2, and a pressure-resistant mechanism 4 installed inside the double-walled oil tank body 3.
[0025] See Figure 3 and Figure 4Furthermore, the disassembly and assembly mechanism 2 includes a fixed base plate 201 fixedly connected to the bottom of the inner wall of the ground groove 1. The top of the fixed base plate 201 is symmetrically provided with an installation groove 202. Both ends of the fixed base plate 201 are symmetrically provided with square holes that extend into the installation groove 202. Both ends of the four square holes are connected to sliding grooves 203. The inner walls of the four sets of sliding grooves 203 are slidably connected with sliders 204. Springs 205 are fixedly connected between the four sets of sliders 204 and the sliding grooves 203. Limiting posts 206 are fixedly connected between the four sets of sliders 204. One end of the outer side of the two sets of limiting posts 206 is fixedly connected with a connecting plate 207. The bottom end of the double-layer oil tank body 3 is symmetrically fixedly connected with an installation plate 208. The two installation plates are symmetrically provided with limiting grooves 209 that are adapted to the limiting posts 206 at their opposite ends.
[0026] Specifically, during installation, the mounting plate 208 is inserted into the mounting groove 202. Since the limiting posts 206 have inclined surfaces at their close ends, the limiting posts 206 can retract into the square holes. After the mounting plate 208 is fully installed, the elastic reset action of the spring 205 can reset the slider 204, thereby resetting the limiting posts 206 and locking them in the limiting groove 209, completing the limiting operation of the mounting plate 208, thus quickly completing the installation of the double-layer oil tank body 3.
[0027] Example 2
[0028] See Figure 5 Furthermore, based on Embodiment 1, the pressure-resistant mechanism 4 includes a first pressure-resistant plate 401 and a second pressure-resistant plate 402 disposed on the inner wall of the double-layer oil tank body 3. The first pressure-resistant plate 401 and the second pressure-resistant plate 402 are fixedly connected to each other, and multiple connecting holes 403 are provided on both the first pressure-resistant plate 401 and the second pressure-resistant plate 402.
[0029] Specifically, with the cooperation of the first pressure-resistant plate 401 and the second pressure-resistant plate 402, the double-layer oil tank body 3 can be supported, thereby improving the overall pressure resistance and extending the service life. In addition, the connecting hole 403 can make the internal oil flow.
[0030] Example 3
[0031] See Figure 1 , Figure 2 and Figure 5Furthermore, based on Embodiment 1 and Embodiment 2, the double-layer oil tank body 3 includes an outer shell 301 and an inner tank 302. The inner tank 302 is located inside the outer shell 301 and is fixedly connected to the first pressure-resistant plate 401 and the second pressure-resistant plate 402. A leakage detector 5 is fixedly connected to the top of the double-layer oil tank body 3. A protective cover 6 is fixedly connected to the outside of the leakage detector 5 at the top of the double-layer oil tank body 3. Hooks are fixedly connected to the four corners of the top of the double-layer oil tank body 3. The four hooks are symmetrically distributed about the center line of the double-layer oil tank body 3. The four limiting posts 206 are all provided with inclined surfaces at one end close to each other. The four limiting posts 206 are all located on the inner wall of the square hole.
[0032] Specifically, both the outer shell 301 and the inner tank 302 of the oil tank are made of titanium alloy. Titanium alloy has extremely high strength and excellent corrosion resistance. The advantages of titanium alloy include high strength, low density, good thermal conductivity and strength, and good pressure resistance. The leakage detector 5 can detect the leakage of oil inside the double-walled oil tank body 3, so as to know whether leakage has occurred. The leakage detector 5 is protected by the protective cover 6 to extend its service life. The hook can keep it in a balanced and stable state during lifting to prevent tilting.
[0033] In actual operation, the double-walled oil tank body 3 is first lifted by the hook and then placed in the ground groove 1. The mounting plate 208 is aligned with the mounting groove 202 and installed into the mounting groove 202. The weight of the double-walled oil tank body 3 will squeeze the inclined surface of the limiting post 206 and make it retract into the square hole. When the mounting plate 208 is fully installed in the mounting groove 202, the elasticity of the spring 205 can make the slider 204 and the limiting post 206 perform a reset movement, so that the limiting post 206 can be inserted into the limiting groove 209 to complete the limiting operation. Therefore, the installation of the double-walled oil tank body 3 can be completed quickly. Similarly, the connecting plate 207 can be used to move the limiting post 206 outward to move it away from the range of the limiting groove 209, so that the disassembly and assembly operation can be completed quickly, thereby improving the overall disassembly and assembly efficiency and saving disassembly and assembly time.
[0034] After installation, the first pressure-resistant plate 401 and the second pressure-resistant plate 402 can provide support inside the inner tank 302, thereby improving the pressure resistance of the double-layer tank body 3. Furthermore, during use, both the outer shell 301 and the inner tank 302 are made of titanium alloy, which further enhances the overall pressure resistance and extends the service life.
[0035] 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 the 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.
