The national standard GB / T 5524-2008 "Animal and Plant Oil Sampling" stipulates: "Bulk oil takes one oil tank (cargo position) as an inspection unit, and uses a fat sampler to take samples in layers from the inspection port or sampling port on the tank top. At least three samples should be collected from the "top", "middle" and "bottom". The "top" sample is collected at 1 / 10 of the total depth; the "middle" sample is collected at 1 / 2 of the total depth; the "bottom" sample is collected at 9 / 10 of the total depth and at least 100mm from the bottom of the tank. Take 1 sample each from the "top" and "bottom" samples, and take 3 samples from the "middle" sample to generate a mixed original finished product."

[0003] In the related art, connecting pipes are respectively arranged at 1 / 10, 1 / 2, and 9 / 10 of the oil storage tank, and each connecting pipe is connected to an oil storage device.

[0039] See also Figure 3 and Figure 7 In one embodiment of the utility model, the portable liquid sampling box 1000 includes a box body 1, a liquid level detection member 2, a sampling structure 3 and a sample collection bottle 4. The box body 1 is provided with a cavity 11 having a cavity 111; the liquid level detection member 2 is accommodated in the cavity 11 and is used to detect the liquid level position of the liquid to be sampled; the sampling structure 3 includes a pumping component 31 and a winch component 32 accommodated in the cavity 11, and the pumping component 31 includes a It includes a pump body 311 and a sampling tube 312, the pump body 311 is provided with a liquid inlet 311a and a liquid outlet 311b, one end of the sampling tube 312 is connected with the liquid inlet 311a, the sampling tube 312 is spirally wound around the winch assembly 32, and the winch assembly 32 is used to drive the sampling tube 312 to release or recover; the sample collecting bottle 4 is accommodated in the cavity 11, and the sample collecting bottle 4 is connected with the liquid outlet 311b.

[0040] In the technical solution of the utility model, when sampling the liquid to be sampled in the liquid storage tank, the portable liquid sampling box 1000 is placed at the tank mouth of the liquid storage tank, so that the liquid level detection component 2 can pass through the cavity mouth 111 of the cavity 11 to measure the liquid surface position of the liquid to be sampled in the liquid storage tank, and then obtain the actual volume of the liquid to be sampled, the hoisting assembly 32 drives the sampling tube 312 to extend through the cavity mouth 111 of the cavity 11, and releases the sampling tube 312 to the positions of 1 / 10, 1 / 2, and 9 / 10 of the actual volume of the liquid to be sampled in turn to control the pump body 311 to perform 1:3:1 sampling, and The obtained samples are collected into the sample collecting bottle 4, and after being fully shaken, they are formed into test samples for testing; after the sampling is completed, the pump body 311 controls the backflushing to clean the residual sample liquid in the sampling tube 312, so as to prevent the residual liquid in the body sampling operation from contaminating the liquid in the next sampling operation, and the winch assembly 32 drives the sampling tube 312 to be recovered to complete the operation; the technical solution provided by the utility model can adapt to complex and changeable sampling situations, and can also realize the fixed-point, positioned, and quantitative sampling of different layers of the liquid to be sampled in the liquid storage tank, meet the national standard requirements for sampling of the liquid to be sampled, and improve the degree of automation and production efficiency of sampling.

[0041] The hoisting assembly 32 may be a servo reducer 322 or a driving motor, and the present invention does not impose any restrictions on this. The liquid level detection component 2 may be a radar liquid level detector or an ultrasonic liquid level detector, and the present invention does not impose any restrictions on this. The pump body 311 is usually a motor that drives the impeller or piston of the pump to rotate or reciprocate, thereby generating suction so that the liquid is sucked into the pump body 311. By controlling the speed of the motor or the frequency of the reciprocating motion, the amount of liquid sucked by the pump body 311 can be controlled, thereby achieving quantitative sampling.

[0042] To improve sampling stability and accuracy, refer to Figure 3 and Figure 6In one embodiment of the utility model, the sampling structure 3 includes a weight assembly 33, and the weight assembly 33 includes a hammer body 331. The hammer body 331 is provided with a through hole 331a. The end of the sampling tube 312 away from the pump body 311 is connected to the hammer body 331 and communicates with the through hole 331a. When the hoist assembly 32 releases the sampling tube 312 to enter the liquid to be sampled for sampling, the pump body 311 is controlled to generate suction so that the liquid to be sampled enters the sampling tube 312 through the through hole 331a, and flows through the liquid inlet 311a, the pump body 311 and the liquid outlet 311b in sequence to enter the sample collection bottle 4; the setting of the hammer body 331 can help the sampling tube 312 to be better inserted into the liquid to be sampled, and the weight of the hammer body 331 can increase the downward pressure of the sampling tube 312, so that it can enter the liquid to be sampled more deeply, thereby obtaining more accurate results. The hammer 331 can also help stabilize the position of the sampling tube 312. During the sampling process, the sampling tube 312 may be offset or moved due to the flow, vibration or other interference factors of the sampled liquid. The presence of the hammer 331 can increase the stability of the sampling tube 312 and reduce the influence of external interference on its position, thereby ensuring the accuracy of sampling. In addition, the hammer 331 can also play a balancing role to prevent the sampling tube 312 from tilting or tipping over during the sampling process, which is crucial to ensure the continuity and integrity of sampling.

[0043] To improve the reliability of sampling operations, refer to Figure 3 and Figure 6 In one embodiment of the present invention, the weight assembly 33 includes a filter sleeve 332, which is covered at one end of the hammer body 331 away from the sampling tube 312, and the filter sleeve 332 is provided with a plurality of liquid holes 332a connected with the through hole 331a. The filter sleeve 332 is provided with a plurality of liquid holes 332a, so that the grease flow can be dispersed into a plurality of channels, and the flow rate and pressure of the grease in a single channel can be reduced. At the same time, the plurality of liquid holes 332a increase the contact area between the grease and the filter material inside the filter sleeve 332, which helps to improve the filtering effect. By filtering out more impurities and particulate matter, the possibility of accumulation and blockage of these substances in the sampling tube 312 can be reduced. Even if a channel is partially blocked due to crude oil precipitation, wax grease precipitation or grease solidification, other channels can still maintain a certain flow capacity, thereby avoiding the complete blockage of the entire sampling tube 312, making the sampling operation more reliable.

[0044] See also Figure 3 and Figure 6In one embodiment of the present invention, the weight assembly 33 further includes a connector 333, the connector 333 is provided with a liquid inlet 333a connected to the through hole 331a, and the two ends of the connector 333 are respectively connected to the hammer body 331 and the sampling tube 312. When the hoist assembly 32 releases the sampling tube 312 to enter the liquid to be sampled for sampling, the pump body 311 is controlled to generate suction so that the liquid to be sampled enters the liquid inlet 333a and the sampling tube 312 through the through hole 331a, and flows through the liquid inlet 311a, the pump body 311 and the liquid outlet 311b in sequence into the sample collection bottle 4; the connection between the connector 333 and the hammer body 331 can be threaded or clamped, and the present invention does not limit this; the connection between the connector 333 and the sampling tube 312 can be clamped or flanged, and the present invention does not limit this.

[0045] See also Figure 6 In one embodiment, the cross-sectional area of ​​the end of the connector 333 close to the sampling tube 312 gradually increases from the end close to the sampling tube 312 to the end far from the sampling tube 312. Such a configuration can significantly improve the sealing performance of the connector 333, so that the sampling tube 312 and the connector 333 can fit together more closely when connected, thereby reducing the possibility of leakage.

[0046] See also Figure 3 and Figure 6 In one embodiment of the present invention, the weight assembly 33 further includes a pull rope 334, one end of which is connected to the hammer body 331, and the other end of which is connected to the hoist assembly 32, and is coiled around the hoist assembly 32.

When sampling, the hoist assembly 32 drives the pull rope 334 to loosen, so that the hammer body 331 drives the sampling tube 312 to be lowered into the liquid to be sampled to achieve sampling. The hoist assembly 32 can control the height of the hammer body 331 by controlling the number of rotations, thereby accurately controlling the fixed-point and positioning sampling of different layers of the liquid to be sampled.

The reducer 322 is connected to the driving member 321 to meet the high torque and low speed output of the rotating shaft 323, thereby meeting the actual control requirements, making the rotation of the rotating shaft 323 more stable. The rotating shaft 323 further drives the winch wheel 324 to rotate to achieve the loosening and recovery of the pull rope 334, so as to drive the hammer 331 and the sampling tube 312 to descend or rise to achieve sampling; an annular groove 324a is provided on the winch wheel 324 to ensure that the pull rope 334 will not shift during loosening and recovery, so that the pull rope 334 can be limited in the annular groove 324a, and the pull rope 334 is prevented from interfering with other components, thereby improving the stability of the sampling operation.
