Description

Technical Field

[0001] The utility model relates to the technical field of gasoline detection sampling, in particular to a sampler for methanol gasoline detection. Background Art

[0002] Methanol gasoline refers to a new type of environmentally friendly fuel made by mixing national standard gasoline, methanol and additives in a certain volume (mass) ratio through a strict process. It is a substitute for automotive fuel and an important component of new energy. After methanol gasoline is produced, it needs to be tested in accordance with relevant standards and through professional means. Before testing methanol gasoline, it is necessary to sample the methanol gasoline to be tested. When sampling, the methanol gasoline is usually extracted by inserting a hose connected to a machine sampling tube into the tank.

[0003] During sampling, since the tank body is made of opaque material, the amount of oil inside the tank body is not easy to observe, and therefore it is not easy to observe whether the hose is inserted into the methanol gasoline. When the hose is not inserted into the methanol gasoline, the oil gas and air inside the tank body will enter the sampling tube, causing the pressure inside the sampling tube to increase, and the effect of negative pressure extraction of methanol gasoline will decrease. After the sampling is completed, the methanol gasoline inside the hose will drip to the ground when the sampling tube and the hose are separated, causing the ground to be dirty and also resulting in waste of this part of the methanol gasoline. Utility Model Content

[0004] The purpose of the utility model is to provide a sampler for detecting methanol gasoline to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A sampler for methanol gasoline detection, comprising:

[0007] A sampling assembly, the sampling assembly comprising a sampling tube, a baffle fixedly mounted on the upper end of the inner surface of the sampling tube, and two one-way tubes fixedly embedded on the upper surface of the baffle;

[0008] A connecting assembly is arranged at the upper end of the sampling tube, the connecting assembly includes a connecting cover movably sleeved on the upper end of the sampling tube, and an air pump is fixedly mounted on the upper surface of the connecting cover;

[0009] The storage component is fixedly mounted on the upper surface of the connection cover. The storage component comprises an air chamber fixedly mounted on the upper surface of the connection cover. A piston plate is slidably connected to the interior of the air chamber.

[0010] Furthermore, a support frame is fixedly installed on the inner surface of the one-way tube, a step rod is fixedly installed on the upper surface of the support frame, a step ring is movably sleeved on the outer side of the step rod, and a spring is fixedly connected between the support frame and the step ring.

[0011] Furthermore, a plurality of slots are provided at equal angles on the outer surface of the sampling tube, and a limiting ring is fixedly installed below the slots on the outer surface of the sampling tube.

[0012] Furthermore, a plurality of elastic clips are fixedly embedded and connected at equal angles at the lower end of the connection cover, and the elastic clips are movably engaged with adjacent slots. Threaded grooves are provided on the outer surfaces of the connection cover and the elastic clips, and a threaded ring is screwed on the outer side of the threaded groove.

[0013] Furthermore, a connecting pipe and an exhaust pipe are fixedly embedded in the upper surface of the connecting cover, the connecting pipe and the exhaust pipe are movably connected to the adjacent one-way pipes respectively, and one end of the air pump is fixedly connected to the exhaust pipe.

[0014] Furthermore, the storage component further comprises:

[0015] A push rod is fixedly mounted on the upper surface of the piston plate;

[0016] an air pipe, fixedly connected between the air chamber and the air pump;

[0017] The motor is fixedly mounted on the upper surface of the gas bin.

[0018] Preferably, the push rod slides through the upper surface of the air chamber, a rack is fixedly embedded in the outer surface of the push rod, and a gear movably meshed with the rack is fixedly installed on the output end of the motor.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Use the elastic clip to clip into the slot, rotate the threaded ring, cover the multiple elastic clips from the outside, fix the sampling tube and the connecting cover to prevent the sampling tube from falling, push the step ring downward with the connecting pipe and the exhaust pipe, separate the step ring from the step rod, open the one-way tube, and allow gas and liquid to enter and discharge the sampling tube. Conversely, remove the sampling tube, reset the step ring, block the one-way tube, and store the methanol gasoline inside the sampling tube.

[0021] 2. The air pump is running to suck the methanol gasoline inside the tank into the sampling tube. When the hose does not penetrate into the methanol gasoline, the oil, gas and air inside the tank are extracted into the gas chamber, reducing the space occupied by air and oil and gas inside the gas chamber, allowing the methanol gasoline to smoothly enter the sampling tube. At the same time, it prevents oil, gas and air from occupying the space inside the sampling tube when the outside world is not excluded, maintaining the effect of negative pressure extraction of methanol gasoline.

[0022] 3. The motor runs, driving the gear to rotate, pushing the rack to move, and moving the piston plate up, discharging the oil, gas and air temporarily stored in the gas chamber into the sampling tube, allowing the oil, gas and air to enter the hose from the connecting pipe. By refluxing the oil, gas and air inside the gas chamber, the methanol gasoline inside the hose is pushed back into the tank, preventing the methanol gasoline from dripping onto the ground when the sampling tube and the hose are separated, thereby preventing the ground from being dirty and wasting methanol gasoline.

The sampling component 1 includes a sampling tube 101, a baffle 104 is fixedly installed at the upper end of the inner surface of the sampling tube 101, and two one-way tubes 105 are fixedly embedded and installed on the upper surface of the baffle 104; the connecting component 2 is arranged at the upper end of the sampling tube 101, and the connecting component 2 includes a connecting cover 201 that is movably sleeved on the upper end of the sampling tube 101, and an air pump 207 is fixedly installed on the upper surface of the connecting cover 201; the storage component 3 is fixedly installed on the upper surface of the connecting cover 201, and the storage component 3 includes an air tank 301 fixedly installed on the upper surface of the connecting cover 201, and a piston plate 303 is slidably connected to the inside of the air tank 301.

[0031] Specifically, a hose is connected via the connecting pipe 205 and inserted into the tank containing methanol gasoline for sampling. The air pump 207 is operated to create a negative pressure environment inside the sampling tube 101 for extracting methanol gasoline. The gas tank 301 temporarily stores the extracted oil, gas and air.

[0032] Example 1

[0033] like Figure 5 As shown, in this embodiment, a support frame 106 is fixedly installed on the inner surface of the one-way tube 105, a step rod 107 is fixedly installed on the upper surface of the support frame 106, a step ring 108 is movably sleeved on the outer side of the step rod 107, and a spring 109 is fixedly connected between the support frame 106 and the step ring 108.

[0034] In this embodiment, the sampling tube 101 is inserted into the connecting cover 201, the connecting tube 205 and the exhaust pipe 206 are inserted into the two one-way tubes 105, the stepped ring 108 is pushed downward, the stepped ring 108 is separated from the stepped rod 107, and the one-way tube 105 is opened, so that gas and liquid can enter and discharge the sampling tube 101. Conversely, the sampling tube 101 is disassembled, the stepped ring 108 is reset, and the one-way tube 105 is blocked, so that methanol gasoline is stored in the sampling tube 101.

[0035] like Figure 2-4 As shown, in this embodiment, a connecting pipe 205 and an exhaust pipe 206 are fixedly embedded and installed on the upper surface of the connecting cover 201, and the connecting pipe 205 and the exhaust pipe 206 are respectively movably connected to the adjacent one-way pipe 105, and one end of the air pump 207 is fixedly connected to the exhaust pipe 206; the storage assembly 3 also includes: a push rod 304 is fixedly installed on the upper surface of the piston plate 303; the air pipe 302 is fixedly connected between the air tank 301 and the air pump 207; the motor 306 is fixedly installed on the upper surface of the air tank 301; the push rod 304 slides through the upper surface of the air tank 301, and a rack 305 is fixedly embedded and installed on the outer surface of the push rod 304, and a gear 307 movably engaged with the rack 305 is fixedly installed on the output end of the motor 306.

[0036] During the specific implementation, the air pump 207 is operated to extract the air inside the sampling tube 101, and a negative pressure environment is created therein, and the methanol gasoline inside the tank body is sucked into the sampling tube 101. When the hose does not penetrate into the interior of the methanol gasoline, the oil gas and air inside the tank body are extracted into the gas tank 301, reducing the space inside the gas tank 301 occupied by air and oil gas, so that the methanol gasoline can smoothly enter the sampling tube 101, and at the same time avoid oil gas and air occupying the space inside the sampling tube 101 when the outside is not excluded, and maintain negative pressure to extract methanol gasoline.

By refluxing the oil, gas and air in the gas chamber 301, the methanol gasoline in the hose is pushed back to the tank body, preventing the methanol gasoline from dripping onto the ground when the sampling tube 101 and the hose are separated, so as to avoid dirtying the ground and wasting methanol gasoline.

[0040] During specific implementation, when the sampling tube 101 is inserted into the connecting cover 201, the elastic clip 203 is stuck in the slot 102, and the threaded ring 204 is rotated to cover the outside of the elastic clip 203, covering multiple elastic clips 203 from the outside to prevent the elastic clips 203 from elastically deforming outward, fixing the sampling tube 101 and the connecting cover 201 to prevent the sampling tube 101 from falling.
