Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a sampling device used for liquid detection and analysis in a tank truck. Background Art

[0002] Tank trucks are an important means of transporting liquid materials. Before the liquid materials are transported to the factory for unloading, they must first be sampled and tested for quality analysis to ensure that the liquid materials meet the quality requirements before unloading operations can be carried out.

[0003] Currently, most beaker sampling is performed from the sampling port on the top of the tank truck. However, it is not easy to sample deeply from the bottom of the tank truck using the beaker sampling method, resulting in poor uniformity of the samples obtained, which can easily cause errors in detection and analysis. In addition, the sample is prone to spillage when being poured into the sampling bottle after sampling. Utility Model Content

[0004] The utility model aims to provide a sampling device for liquid detection and analysis in a tank truck, which is used to solve the problems of poor sample uniformity caused by sampling through a beaker and easy sample spillage during the process of pouring the sample into a sampling bottle.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling device for liquid detection and analysis in a tank truck, comprising a beaker and an extraction mechanism arranged on the beaker, the beaker comprising a cup body, a discharge pipe arranged at the lower end of the cup body and integrally formed with the cup body, and a discharge valve arranged on the discharge pipe section; the extraction mechanism comprises a fixed component arranged in the middle and upper part of the cup body, an electric telescopic rod arranged on the fixed component, a power supply component arranged on the electric telescopic rod, and handles arranged on both sides of the power supply component.

[0006] Furthermore, the fixing assembly includes multiple fixing plates arranged on the inner wall of the cup body, a circular plate connected to one end of the multiple fixing plates, and an assembly structure arranged on the upper side of the circular plate, and the assembly structure is arranged at the lower end of the electric telescopic rod.

[0007] Furthermore, a plurality of overflow holes are formed through the fixing plate.

[0008] Furthermore, the assembly structure includes a threaded rod arranged on a circular plate, and a threaded sleeve threadably matched with the threaded rod, and the threaded sleeve is arranged at the lower end of the electric telescopic rod.

[0009] Furthermore, the bottom of the cup body is in a cone shape.

[0010] Furthermore, the power supply assembly includes a power supply housing, a battery disposed in the power supply housing, and a switch disposed on the power supply housing, and the switch is electrically connected between the electric telescopic rod and the battery.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model has the following beneficial effects:

[0013] When using the device to sample liquid in a tank truck, hold the two handles to extend the cup into the liquid in the tank truck through the sampling port of the tank truck, and press the switch according to the depth of the liquid in the tank truck to change the telescopic length of the electric telescopic rod so that the cup extends into the bottom of the liquid. When holding the two handles and pulling the cup upward, ensure that the sample is taken from the bottom of the liquid upward, thereby ensuring the uniformity of the sampling;

[0014] After sampling, place the discharge pipe at the bottom of the cup into the mouth of the sampling bottle, open the discharge valve, and let the sample flow into the sampling bottle, effectively preventing the sample from spilling. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-4 A sampling device for liquid detection and analysis in a tank truck includes a beaker 1 and an extraction mechanism arranged on the beaker 1. The beaker 1 includes a cup body 2, a discharge pipe 3 arranged at the lower end of the cup body 2 and forming an integral structure with the cup body 2, and a discharge valve 4 installed on the pipe section of the discharge pipe 3; the extraction mechanism includes a fixed component arranged in the middle and upper part of the cup body 2, an electric telescopic rod 5 arranged on the fixed component, a power supply component arranged on the electric telescopic rod 5, and handles 7 welded on both sides of the power supply component.

[0021] The fixing assembly includes multiple fixing plates 9 welded to the inner wall of the cup body 2, a circular plate 10 welded to one end of the multiple fixing plates 9, and an assembly structure arranged on the upper side of the circular plate 10. The multiple fixing plates 9 are arranged at an angle, and the assembly structure is arranged at the lower end of the electric telescopic rod 5.

[0022] A plurality of overflow holes 14 are formed through the fixing plate 9 , which can effectively prevent liquid from being retained on the fixing plate 9 .

[0023] The assembly structure includes a threaded rod 11 welded on a circular plate 10, and a threaded sleeve 12 threadably matched with the threaded rod 11, and the threaded sleeve 12 is welded to the lower end of the electric telescopic rod 5; when the extraction mechanism and the cup body 2 are disassembled, the threaded rod 11 is rotated out of the threaded sleeve 12, which facilitates the disassembly and replacement of the extraction mechanism.

[0024] The bottom of the cup body 2 is in a cone shape; when the cup body 2 enters the liquid, the resistance of the cup body 2 when extending into the deep part of the liquid is effectively reduced, making the operation more labor-saving.

[0025] The cup body 2, discharge valve 4, fixing plate 9, circular plate 10, threaded rod 11, threaded sleeve 12 and handle 7 are made of stainless steel or copper, which effectively prevents sparks and rust corrosion caused by friction during sampling, ensures the safety of sampling and prolongs the service life of the equipment.

[0027] Working principle: When using the device to sample liquid in a tank truck, hold the two handles 7 to extend the cup body 2 into the liquid in the tank truck through the sampling port of the tank truck, and press the switch 13 according to the depth of the liquid in the tank truck to change the telescopic length of the electric telescopic rod 5, so that the cup body 2 extends into the bottom of the liquid. When holding the two handles 7 and pulling the cup body 2 upward, it is ensured that the sampling is taken from the bottom of the liquid upward, thereby ensuring the uniformity of the sampling; after the sampling is completed, the discharge pipe 3 arranged at the bottom of the cup body 2 is placed into the sampling bottle mouth, and the discharge valve 4 is opened to allow the sample to flow into the sampling bottle, effectively preventing the sample from being spilled.
