Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery technology, specifically to an oil and gas recovery detection device for gas stations. Background Technology

[0002] In recent years, with increased environmental awareness and enforcement, higher standards have been set for oil and gas emissions from gas stations. According to the requirements of the "GB20952-2020 Emission Standard for Air Pollutants from Gas Stations," gas stations across China have been gradually installing secondary oil and gas recovery systems. Environmental protection departments use oil and gas recovery detectors and oil storage tanks to conduct fuel dispensing tests during actual spot checks and online monitoring of gas station equipment installation and commissioning by manufacturers. This ensures that the oil and gas recovery system of the fuel dispenser meets the relevant standards, specifically the gas-liquid ratio requirement of 1.0-1.2.

[0003] For example, existing patent CN209759018U discloses a detection device for vapor recovery at gas stations, which can lift and lower oil drums to facilitate the automatic return of gasoline inside, thus improving work efficiency. The detection device is equipped with fixed rollers at the bottom, which can move the device on flat ground. However, when going up or down stairs, these rollers cannot move the detection device smoothly and effortlessly. When going up or down stairs or steps, staff may need to carry it rather than push or pull it, which could lead to bumps and is very time-consuming and laborious.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a gas station oil and gas recovery detection device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A gas station oil vapor recovery detection device includes a frame and an oil drum. The top of the frame is movably connected to a placement plate for supporting the oil drum. The bottom of the frame has symmetrical ladder mechanisms at both corners for assisting climbing. The ladder mechanism includes a Y-shaped bracket movably connected to the frame. The end of the Y-shaped bracket has a movable wheel movably connected to it. The frame is movably connected to the middle of the Y-shaped bracket via a fixed shaft. A support block is provided on the bottom of the frame away from the movable wheel. The side of the frame has a reinforcement mechanism for fixing the oil drum.

[0008] Preferably, the reinforcement mechanism includes symmetrically arranged arc-shaped frames, with clamping plates on the side of the two sets of arc-shaped frames that are close to each other, and threaded rods that pass through the arc-shaped frames are movably connected on the side of the two sets of clamping plates that are far apart from each other.

[0009] Preferably, the end of the threaded rod is provided with a rotating handle, and the arc-shaped frame is provided with a threaded hole that matches the threaded rod.

[0010] Preferably, the frame is provided with a transversely arranged crossbeam, a lead screw is movably threaded through the crossbeam, and a pressure plate is provided at the bottom of the lead screw.

[0011] Preferably, the top of the lead screw is provided with a roller, the bottom of the pressure plate is provided with a rubber pad, and the crossbeam is provided with a threaded hole that matches the lead screw.

[0012] Preferably, the frame is provided with a side frame vertically on one side of the oil drum, which is connected to the bottom of the crossbeam. The frame is provided with a limiting groove for guiding the vertical movement of the side frame, and the bottom of the side frame is provided with a connecting frame connected to the placement plate.

[0013] Preferably, the top of the frame is provided with a sprocket, and a chain connected to the side frame is engaged on the sprocket. The sprocket is movably connected to the frame via a pivot, and the frame is provided with a drive mechanism for driving the pivot to rotate.

[0014] The beneficial effects of this utility model are as follows: With the Y-shaped bracket and movable wheels, when the device goes up or down stairs, the three movable wheels rotate in the same direction when subjected to upward or downward pulling forces. During this process, the three movable wheels take turns contacting the steps, and simultaneously, the Y-shaped bracket and fixed shaft, when subjected to upward or downward pulling forces, also drive each group of three movable wheels to rotate in the same direction. Therefore, it can easily descend or ascend from the current step to the next step. Compared to traditional single movable wheels, this reduces collisions and makes the device more time-saving and labor-saving when going up or down stairs or steps. The reinforcement mechanism design can limit the movement of oil drums of different diameters, improving overall versatility. The screw and pressure plate design can limit the top of the oil drum, further improving the limiting effect and effectively preventing tipping during transportation. The side frame is raised and lowered under the pull of the chain, thereby driving the oil drum to move up and down. Attached Figure Description

[0024] Example 1;

[0025] like Figure 1-4As shown, the gas station oil and gas recovery detection device according to an embodiment of the present utility model includes a frame 1 and an oil drum 2. The top of the frame 1 is movably connected to a placement plate 3 for supporting the oil drum 2.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical applications, through the setting of Y-shaped bracket 4 and movable wheels 5, when the device goes up or down stairs, the three movable wheels 5 will rotate in the same direction when they are pulled upward or downward. When going up or down stairs, the three movable wheels 5 take turns contacting the steps. At the same time, the Y-shaped bracket 4 and the fixed shaft 6 will also drive the three movable wheels 5 in each group to rotate in the same direction when they are pulled upward or downward. Therefore, it is easy to fall down or rise from the current step to the next step. When placing the oil drum 2, place the oil drum 2 on the placement plate 3, rotate the handle 11 to drive the threaded rod 10 to rotate and move, and drive the two sets of clamps 9 to move in the same direction to limit the two sides of the oil drum 2. Rotating the screw 13 will drive the pressure plate 14 to move down to limit the top of the oil drum 2. When it is necessary to lift the oil drum 2, the drive mechanism 20 drives the sprocket 18 to rotate. The sprocket 18 and the chain 19 mesh and pull the side frame 16 to lift along the limiting slide, thereby driving the oil drum 2 to lift.

[0032] In summary, by utilizing the above-mentioned technical solution of this utility model, through the arrangement of the Y-shaped bracket 4 and the movable wheels 5, when the device goes up or down stairs, the three movable wheels 5 will rotate in the same direction when subjected to upward or downward pulling force. When going up or down stairs, the three movable wheels 5 take turns contacting the steps. At the same time, the Y-shaped bracket 4 and the fixed shaft 6 will also drive the three movable wheels 5 in each group to rotate in the same direction when subjected to upward or downward pulling force. Therefore, it can easily fall down or rise from the current step to the next step. Compared with the traditional single movable wheel, it reduces collisions and makes the device more time-saving and labor-saving when going up or down stairs or steps. The design of the reinforcement mechanism can limit the oil drums 2 of different diameters, improving the overall versatility. The setting of the screw 13 and the pressure plate 14 can limit the top of the oil drum 2, further improving the limiting effect and effectively preventing tipping during transportation. The side frame 16 is raised and lowered under the pull of the chain 19, thereby driving the oil drum 2 to move up and down.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
