[0034] Example 1:

[0035] Combination Figs. 1-3 An oil sampling device, comprising:

[0036] Sampling container 10 is connected to the oil outlet of the device to be sampled;

[0037] The housing 3 contains multiple sampling container storage compartments 2; each sampling container storage compartment 2 includes a first frame 201 and a second frame 202 rotatably connected, with the first frame 201 located inside the second frame 202; the first frame 201 stores the sampling container 10; the second frame 202 is provided with at least one constant temperature heating element 204, which heats the sampling container 10; a first channel 206 is opened at the bottom of the first frame 201, and a second channel 207 is opened at the bottom of the second frame 202;

[0038] The oil drain pan 5 is located at the bottom of the housing 3 and can be pulled out; the oil drain pan 5 receives the oil flowing out from the first channel 206 and the second channel 207.

[0039] The above provides an oil sample sampling device that solves the problems of aging existing testing / inspection equipment, the presence of air bubbles in the oil sample, poor sealing, and low accuracy, which affect subsequent test results.

[0040] In this embodiment, the sampling container 10 is an oil sample bottle. Different volumes of oil sample bottles are selected according to the oil sample requirements. Preferably, the outer wall of the oil sample bottle is provided with a hook and loop fastener, allowing the label to be fastened to the outer wall of the bottle without leaving adhesive residue and making it easy to clean.

[0041] In this embodiment, a communication component is provided between the sampling container 10 and the oil outlet of the device to be sampled. Specifically, the communication component includes an oil outlet 6 and a connecting pipe 7. The oil outlet 6 is connected to the oil outlet of the device to be sampled, and the two ends of the connecting pipe 7 are respectively connected to the oil outlet 6 and the sampling container 10. The connecting pipe 7 is provided with an oil drain valve 8.

[0042] Preferably, the connecting assembly further includes a waste oil outlet 9 for discharging waste oil. A tee is provided between the connecting pipe 7 and the waste oil outlet 9. The main pipe of the tee is connected to the connecting pipe, the first branch pipe of the tee is connected to the sampling container 10, and the second branch pipe of the tee is connected to the waste oil outlet 9. Furthermore, a drain valve 8 is provided at the tee, which controls the connection between the main pipe and the first branch pipe or controls the connection between the main pipe and the second branch pipe.

[0043] In this embodiment, multiple sampling container storage cells 2 are arranged in an M×N matrix, where M and N are both natural numbers, M≥2, and N≥2. Specifically, the sampling container storage cells 2 are arranged in a 2×2 matrix, evenly distributed within the housing 3, resulting in a compact design.

[0044] In this embodiment, at least one set of rotating connection components 203 is provided between the first frame 201 and the second frame 202. Specifically, the rotating connection component 203 includes a first bearing, a rotating shaft, and a second bearing. The two ends of the rotating shaft pass through the first bearing and the second bearing, respectively. The first bearing is disposed in the first frame 201, and the second bearing is disposed in the second frame 202.

[0045] In this embodiment, at least one set of anti-slip elements 205 is provided on the inner wall of the first frame 201. Preferably, four sets of anti-slip elements 205 are provided, and the four sets of anti-slip elements 205 are equally spaced on the inner wall of the first frame 201 to increase the friction between the first frame 201 and the oil bottle 10. The anti-slip elements 205 are raised anti-slip pads, which have the functions of shock absorption, anti-slip, and anti-collision.

[0046] In this embodiment, a buffer section is provided at the bottom of the first frame 201. Preferably, the buffer section is a rubber buffer block with a triangular cross-sectional shape. The buffer section reduces the impact force generated when the oil bottle 10 is placed in the sampling container storage cell 2, and avoids damage to the oil bottle 10 caused by the collision between the oil bottle 10 and the sampling container storage cell 2.

[0047] In this embodiment, the central axis of the first channel 206 coincides with the central axis of the second channel 207, allowing excess oil in the sampling container storage cell 2 to flow smoothly out from both the first channel 206 and the second channel 207. Preferably, to concentrate and collect excess oil in the sampling container storage cell 2, the inner diameter of the first channel 206 is smaller than the inner diameter of the second channel 207.

[0048] In this embodiment, a set of sliding grooves are symmetrically arranged along the length of the bottom of the box 3, and the oil leakage tray 5 slides along the direction of the sliding grooves.

[0049] In this embodiment, the housing 3 is provided with a temperature display window 4, which monitors the temperature of the sampling container storage compartment 2.

[0050] Example 2:

[0051] Based on Example 1, an oil sample sampling device includes:

[0052] Sampling container 10 is connected to the oil outlet of the device to be sampled;

[0053] The housing 3 contains multiple sampling container storage compartments 2; each sampling container storage compartment 2 includes a first frame 201 and a second frame 202 rotatably connected, with the first frame 201 located inside the second frame 202; the first frame 201 stores the sampling container 10; the second frame 202 is provided with at least one constant temperature heating element 204, which heats the sampling container 10; a first channel 206 is opened at the bottom of the first frame 201, and a second channel 207 is opened at the bottom of the second frame 202;

[0054] An ultrasonic cleaning tank 1, located on one side of the housing 3, is used to clean items such as the oil outlet 6, connecting pipe 7, and drain valve 8. Specifically, the ultrasonic cleaning tank 1 mainly consists of an ultrasonic generator, a cleaning tank, and a cleaning chamber. The ultrasonic generator comprises a power transformer and rectifier system, an oscillator, a driver stage, a power amplifier, and an output transformer. The cleaning tank consists of a stainless steel tank, a composite transducer, and a matching inductor. The transducer is located at the bottom of the stainless steel tank, and a shock-absorbing device is installed between the stainless steel tank and the housing frame. The cleaning chamber has an ammeter, power switch, output socket, and frequency / phase power series adjustment knob on its panel; a power input socket and fuse are located at the rear. The working principle is as follows: The transducer converts the acoustic energy of the ultrasonic frequency source into mechanical vibration, which then passes through the cleaning tank wall. Due to the radiated ultrasonic waves, the microbubbles in the liquid within the cleaning tank can maintain oscillation under the action of the ultrasonic waves. Ultrasonic waves generate tremendous force. When ultrasonic waves propagate in a liquid, bubbles rapidly increase in size and then suddenly collapse. The impact force directly and repeatedly bursts the dirt layer, which can scrub the solid surface. At the same time, the bubbles "drill" into the cracks and vibrate, which on the one hand breaks the adhesion between the dirt and the object surface; on the other hand, it also causes the dirt layer to break off from the object surface and scatter into the cleaning solution.

[0055] The oil drain pan 5 is located at the bottom of the housing 3 and can be pulled out; the oil drain pan 5 receives the oil flowing out from the first channel 206 and the second channel 207.

[0056] In this embodiment, the sampling container 10 is an oil sample bottle. Different volumes of oil sample bottles are selected according to the oil sample requirements. Preferably, the outer wall of the oil sample bottle is provided with a hook and loop fastener, allowing the label to be fastened to the outer wall of the bottle without leaving adhesive residue and making it easy to clean.

[0057] In this embodiment, a communication component is provided between the sampling container 10 and the oil outlet of the device to be sampled. Specifically, the communication component includes an oil outlet 6 and a connecting pipe 7. The oil outlet 6 is connected to the oil outlet of the device to be sampled, and the two ends of the connecting pipe 7 are respectively connected to the oil outlet 6 and the sampling container 10. The connecting pipe 7 is provided with an oil drain valve 8.

[0058] Preferably, the connecting assembly further includes a waste oil outlet 9 for discharging waste oil. A tee is provided between the connecting pipe 7 and the waste oil outlet 9. The main pipe of the tee is connected to the connecting pipe, the first branch pipe of the tee is connected to the sampling container 10, and the second branch pipe of the tee is connected to the waste oil outlet 9. Furthermore, a drain valve 8 is provided at the tee, which controls the connection between the main pipe and the first branch pipe or controls the connection between the main pipe and the second branch pipe.

[0059] In this embodiment, multiple sampling container storage cells 2 are arranged in an M×N matrix, where M and N are both natural numbers, M≥2, and N≥2. Specifically, the sampling container storage cells 2 are arranged in a 2×2 matrix, evenly distributed within the housing 3, resulting in a compact design.

[0060] In this embodiment, at least one set of rotating connection components 203 is provided between the first frame 201 and the second frame 202. Specifically, the rotating connection component 203 includes a first bearing, a rotating shaft, and a second bearing. The two ends of the rotating shaft pass through the first bearing and the second bearing, respectively. The first bearing is disposed in the first frame 201, and the second bearing is disposed in the second frame 202.

[0061] In this embodiment, at least one set of anti-slip elements 205 is provided on the inner wall of the first frame 201. Preferably, four sets of anti-slip elements 205 are provided, and the four sets of anti-slip elements 205 are equally spaced on the inner wall of the first frame 201 to increase the friction between the first frame 201 and the oil bottle 10. The anti-slip elements 205 are raised anti-slip pads, which have the functions of shock absorption, anti-slip, and anti-collision.

[0062] In this embodiment, a buffer section is provided at the bottom of the first frame 201. Preferably, the buffer section is a rubber buffer block with a triangular cross-sectional shape. The buffer section reduces the impact force generated when the oil bottle 10 is placed in the sampling container storage cell 2, and avoids damage to the oil bottle 10 caused by the collision between the oil bottle 10 and the sampling container storage cell 2.

[0063] In this embodiment, the central axis of the first channel 206 coincides with the central axis of the second channel 207, allowing excess oil in the sampling container storage cell 2 to flow smoothly out from both the first channel 206 and the second channel 207. Preferably, to concentrate and collect excess oil in the sampling container storage cell 2, the inner diameter of the first channel 206 is smaller than the inner diameter of the second channel 207.

[0064] In this embodiment, a set of sliding grooves are symmetrically arranged along the length of the bottom of the box 3, and the oil leakage tray 5 slides along the direction of the sliding grooves.

[0065] In this embodiment, the housing 3 is provided with a temperature display window 4, which monitors the temperature of the sampling container storage compartment 2.

[0066] As can be seen from the above, the difference from Embodiment 1 is that the oil sampling device is equipped with an ultrasonic cleaning tank 1, which can directly clean the sampling components and save time in collecting different oil samples.

[0067] Example 3:

[0068] An oil sampling method, using the oil sampling device provided in Example 1 or Example 2, includes the following steps:

[0069] The sampling container 10 is connected to the device to be sampled and collects the oil sample from the device. The sampling container 10 is placed in the sampling container storage compartment 2. At the same time, the sampling container storage compartment 2 rotates and heats the sampling container 10 to reduce air bubbles in the oil sample inside the sampling container 10.

[0070] Specifically, the oil outlet 6 is connected to the sampling device, and the oil drain valve 8 is manually opened to connect the main pipe of the tee and the first branch pipe of the tee. The sampling container 10 is placed in the sampling container storage compartment 2. The operator moves the first frame 201 so that the first frame 201 and the second frame 202 rotate relative to each other. At the same time, the constant temperature heating element 204 is activated to reduce air bubbles in the oil sample in the sampling container 10.
