Description

Technical Field

[0001] This utility model relates to the field of double-walled oil tank technology, specifically to a double-walled oil tank that is easy to hoist with straps. Background Technology

[0002] Double-walled oil tanks are facilities used to store petroleum products, designed to improve safety, environmental friendliness, and economy. The outer layer of a double-walled tank is typically made of tempered fiberglass or steel plate, offering excellent pressure and shock resistance as well as corrosion resistance. A unique manufacturing process between the inner and outer layers ensures a complete vacuum, eliminating potential hazards at the source. 24-hour real-time leak detection further ensures safety. Double-walled oil tanks are widely used in gas stations, oil depots, and other similar locations, with market demand continuing to grow, especially given increasingly stringent environmental regulations. With rising environmental awareness and technological advancements, the market demand for double-walled oil tanks continues to grow, particularly in their increasingly widespread application at gas stations and oil depots.

[0003] The utility model patent, titled "A Leak-Proof Double-Layer Oil Tank" (application number 202322864257.9), proposes that "this utility model relates to the field of oil technology and discloses a leak-proof double-layer oil tank, including an outer tank body. A warning light is provided on the outer surface of the outer tank body, and a base is fixedly connected to the lower surface of the outer tank body. An leak-proof mechanism is provided inside the outer tank body, and a moving mechanism is provided on the base. The leak-proof mechanism includes an inner tank body, which is located inside the outer tank body. A connecting column is fixedly connected between the outer surface of the inner tank body and the inner wall of the outer tank body. A liquid level sensor is provided on the bottom wall of the outer tank body. In this leak-proof double-layer oil tank, oil will trigger the liquid level sensor, causing the liquid level sensor to transmit a signal to a controller. The controller then controls a solenoid valve to start, allowing the oil in the outer tank body to be quickly collected into the storage tank, preventing oil leakage and improving the safety of the double-layer oil tank. Furthermore, collecting leaked oil is convenient and quick, saving manpower and avoiding oil waste." However, this utility model patent has the following problems:

[0004] 1. The application did not take into account the need to move the double-walled oil tank by means of hoisting with straps, and did not set up relevant structures to fix the straps used for hoisting. This approach is not good, which will result in poor fixation of the straps and easy slippage, which will lead to the double-walled oil tank slipping and breaking, and thus cannot achieve the best handling effect.

[0005] 2. The application did not consider that the base for placing the double-walled oil tank is separate from the double-walled oil tank. After moving the double-walled oil tank, an additional base needs to be placed for placing the double-walled oil tank. Traditional double-walled oil tanks with their own bases may rotate under force when the double-walled oil tank is moved, which will affect the placement of the double-walled oil tank and cannot achieve the best treatment effect.

Detailed Implementation

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown, a double-walled oil tank that is easy to hoist with straps includes an outer tank body 1, a connector 2, an inner tank body 3, a discharge port 4, a connecting pipe 5, and a storage tank 6. The outer tank body 1 is provided with a rack 7, the rack 7 is matched with a rotating cover 8, the rotating cover 8 is equipped with a first outer box 9, the first outer box 9 is equipped with a second outer box 10, the first outer box 9 is equipped with a first spring 11, the first spring 11 is equipped with a first slider 12 that matches the first outer box 9, and the first slider 12 is equipped with a first limiting rod 13 that matches the rack 7.

[0025] The rotating cover 8 is equipped with a support ring 19 and a support base 20.

[0026] Working principle explanation:

[0027] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, the basic function of this device is the same as that of the utility model patent titled "Anti-Leakage Double-Layer Oil Tank" (application number 202322864257.9). The outer tank 1 and the inner tank 3 are securely connected by the connector 2. The oil in the inner tank 3 is stored and discharged through the discharge port 4. The oil leaking from the inner tank 3 flows into the outer tank 1 and is discharged into the storage tank 6 through the connecting pipe 5. It is worth noting that the double-layer oil tank is placed on the ground by the support base 20. When the double-layer oil tank needs to be moved, the straps are installed on the support ring 19 installed on the rotating cover 8 for movement. Even if the double-layer oil tank rotates due to external forces during the movement, the first limit rod 13 is pulled to compress the first slider 12 and the first spring 11. The first limit rod 13 is separated from the rack 7. At this time, the rotating cover 8 can rotate. Therefore, the position of the support base 20 and the double-layer oil tank can be adjusted as needed to facilitate the placement of the double-layer oil tank.

[0028] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: a second spring 14 is installed on the second outer box 10, a second slider 15 matching the second outer box 10 is installed on the second spring 14, a second limiting rod 16 is installed on the second slider 15, and a first limiting rod 13 is provided with a first hole 17 matching the second limiting rod 16. It is worth noting that when it is necessary to switch the rotating cover 8 to the rotating mode, the first limiting rod 13 is pulled, and the rotating cover 8 is in the rotating mode. Under the rebound action of the second spring 14, the second slider 15 rebounds and inserts the second limiting rod 16 into the first hole 17 to fix the first limiting rod 13. When it is necessary to switch the rotating cover 8 to the fixed mode, the second limiting rod 16 is pulled, causing the second slider 15 to compress the second spring 14 and simultaneously disengage from the first hole 17. The first spring 11 rebounds and fixes the first slider 12 and the first limiting block 13 to the rack 7. This structural design allows the rotating cover 8 to be adjusted to the fixed mode and the rotating mode as needed.

[0029] Example 3, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment adds the following structure based on embodiment 1: the first limiting rod 13 is provided with a second hole 18 that matches the second limiting rod 16. It is worth noting that when the rotating cover 8 is switched to the fixed mode, the first limiting rod 13 may be affected by external force or accidentally touched. Therefore, when the rotating cover 8 is switched to the fixed mode, the second spring 14 rebounds and inserts the second slider 15 and the second limiting rod 16 into the second hole 18 for limiting and fixing. This structural design allows the first limiting rod 13 to be fixed even when not in use, making the first limiting rod 13 more stable and preventing accidental touch.

[0030] Example 4, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the support base 20 is provided with a sliding groove 21, the sliding groove 21 is equipped with a third spring 22, the third spring 22 is equipped with a third slider 23, the third slider 23 is equipped with a pull rod 24 and a third limiting rod 25. It is worth noting that when the strap is installed, pulling the pull rod 24 causes the third slider 23 to compress the third spring 22 and drive the third limiting rod 25 to move. After the strap is installed, the pull rod 24 is released, the third spring 22 rebounds and causes the third limiting rod 25 to move and limit and fix the strap. This structural design allows the strap to be better fixed and prevents the strap from sliding and causing the double-layer oil tank to fall.

[0031] Example 5, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the support ring 19 is provided with a limiting groove 26 that matches the third limiting rod 25. It is worth noting that the third spring 22 rebounds to make the third limiting rod 25 insert into the limiting groove 26 for fixation. This structural design allows the strap to be better fixed, preventing the strap from slipping off and making the installation of the double-layer oil tank more stable.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
