Description

Technical Field

[0001] This utility model relates to the field of calibration technology, specifically to a calibration auxiliary device for an electronic density temperature measuring instrument. Background Technology

[0002] In the fields of oil processing, storage, transportation, and trade settlement, accurate measurement of oil density and temperature is a core element in ensuring fair measurement, production safety, and process stability. With the development of automation technology, portable electronic density and temperature measuring instruments are gradually replacing traditional manual measurement methods due to their advantages such as ease of operation and fast measurement speed. They are widely used in on-site testing in scenarios such as oil tankers and tank trucks, and can directly output the standard density of oil products at a reference temperature of 20℃ that meets national standards, significantly reducing the intensity of manual labor and time costs.

[0003] However, as a measuring device, the accuracy of electronic measuring instruments is easily affected by factors such as vibration, changes in ambient temperature, and aging of electronic components during long-term use, posing a risk of data deviation. Failure to calibrate in a timely manner will lead to deviations in oil measurement, potentially causing trade disputes or misjudgments in production processes. According to industry requirements, electronic density and temperature measuring instruments generally need to be calibrated monthly, comparing their measurement results with the values ​​of "standard instruments" (standard density meters, standard thermometers) with known accuracy to determine their errors and correction values.

[0004] Existing calibration containers are small in volume and have a fixed structure, making it impossible to simultaneously accommodate electronic measuring instrument probes and manual measuring tools. This results in the inability to measure both simultaneously in the same oil sample and under the same environment, requiring the calibration process to be repeated, which is inefficient.

[0005] Therefore, it is necessary to provide an auxiliary device for calibrating an electronic density temperature measuring instrument to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide an auxiliary device for calibration of electronic density temperature measuring instrument, so as to solve the problems mentioned in the background technology.

[0007] The technical solution adopted by this utility model to solve its technical problem is: an auxiliary device for calibrating an electronic density and temperature measuring instrument, comprising a device body welded from metal materials, a top panel and a middle panel with openings installed on the device body, a receiving bottle installed on the middle panel, the receiving bottle having a receiving cavity for collecting and testing oil samples, the receiving bottle being located directly below the opening, an electronic density and temperature measuring instrument, a guide tube for passing through the detection end of the electronic density and temperature measuring instrument, and a placement seat for placing a standard density meter and a standard thermometer are installed on the top panel, the detection end of the electronic density and temperature measuring instrument, the guide tube and the placement seat all corresponding to the receiving cavity.

[0008] Furthermore, the guide tube has two hanging ears and a filter screen. One end of each of the two hanging ears is welded to the top of the filter screen and is symmetrically arranged. The other end of the hanging ears is fixedly connected to the top panel, and the filter screen is located in the receiving cavity.

[0009] Furthermore, the top of the middle panel is provided with a discharge hole, which is concentrically arranged with the container bottle and communicates with the container cavity. One end of the discharge hole is connected to a valve through a pipe.

[0010] Furthermore, the container has a glass bottle body and a metal ring, the bottom of which is welded to the middle panel and the top of which is adhesively connected to the glass bottle body.

[0011] Furthermore, the top panel has an upper mounting groove at the bottom of one side, and the middle panel has a lower mounting groove at the top of one side corresponding to the upper mounting groove. Several sealing glass panels are fixedly connected between the top panel and the middle panel, and the sealing glass panels are distributed around the top panel and the middle panel.

[0012] Furthermore, two of the aforementioned sealing glass panels are slidably mounted between the top panel and the middle panel, with the top of the sealing glass installed in the upper mounting groove and the bottom installed in the lower mounting groove.

[0013] Furthermore, the device body also has a bottom panel and connecting posts, the middle panel is located between the bottom panel and the top panel, and the connecting posts are distributed at the four corners of the bottom panel, the middle panel and the top panel to connect the various panels together. The bottom panel is equipped with casters, the top of the middle panel is equipped with a metal storage basket located on one side of the bottle, and the top panel is equipped with a limiting block for positioning the electronic density and temperature measuring instrument.

[0014] Furthermore, the electronic density temperature measuring instrument is connected to an instrument discharge clamp via a wire, the bottom panel is connected to a device discharge clamp via a wire, and a metal sheet extends downward from the bottom side of the middle panel for the instrument discharge clamp to grip.

[0015] The beneficial effects of this utility model are as follows: This utility model provides an auxiliary device for calibrating an electronic density temperature measuring instrument. The device sets the detection end, guide tube, and placement seat of the electronic density temperature measuring instrument in correspondence with the receiving cavity, ensuring that the detection end of the electronic density temperature measuring instrument, the standard thermometer, and the standard density meter can all measure the oil sample under the same oil sample and the same environment to calibrate the electronic density temperature measuring instrument. This improves the accuracy of the detection and avoids the phenomenon that existing calibration containers have small volume and fixed structure, which cannot simultaneously accommodate the electronic measuring instrument probe and manual measuring tools for simultaneous measurement. By setting up a guide tube, the detection end of the electronic density and temperature measuring instrument is placed inside the filter screen of the guide tube for measurement. This prevents the detection end from touching the inner wall of the container bottle during the descent of the container cavity, and prevents the detection end from contacting the standard thermometer and standard density meter during the measurement process, thus preventing breakage. By installing sealed glass, the space between the top panel and the middle panel is formed into a relatively sealed environment, which is beneficial to environmental protection and has less impact on the measurement results. By incorporating instrument discharge clamps and device discharge clamps, static electricity in the device body and electronic density and temperature measuring instrument is released, preventing static electricity from affecting oil products, avoiding the accumulation of static electricity and the release of energy that could cause a fire, thus improving safety during operation.

[0018] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: an auxiliary device for calibrating an electronic density and temperature measuring instrument, comprising a device body 1 welded from metal materials. The device body 1 has a top panel 13 with an opening 133 and a middle panel 12. A receiving bottle 4 is installed on the middle panel 12, and the receiving bottle 4 has a receiving cavity 41 for collecting and testing oil samples. The receiving bottle 4 is located directly below the opening 133. An electronic density and temperature measuring instrument 7, a guide tube 5 for the detection end of the electronic density and temperature measuring instrument 7, and a placement seat 6 for placing a standard density meter and a standard thermometer are installed on the top panel 13. The detection end of the electronic density and temperature measuring instrument 7, the guide tube 5, and the placement seat 6 all correspond to the receiving cavity 41. This ensures that the detection end of the electronic density and temperature measuring instrument 7, the standard thermometer, and the standard density meter can all measure the oil sample under the same conditions to calibrate the electronic density and temperature measuring instrument 7, improving the accuracy of the test and avoiding the problem of existing calibration containers having small volumes and fixed structures, which cannot simultaneously accommodate the electronic measuring instrument probe and manual measuring tools.

[0021] The guide tube 5 has two lugs 51 and a filter screen 52. One end of each lug 51 is welded to the top of the filter screen 52 and they are symmetrically arranged. The other end of each lug 51 is fixedly connected to the top panel 13. The filter screen 52 is located inside the receiving cavity 41. Placing the detection end of the electronic density and temperature measuring instrument 7 inside the filter screen 52 for measurement can prevent the detection end of the electronic density and temperature measuring instrument from touching the inner wall of the receiving bottle 4 and breaking during the descent of the receiving cavity 41.

[0022] The top of the middle panel 12 is provided with a discharge hole 121. The discharge hole 121 is concentrically arranged with the container bottle 4 and communicates with the container cavity 41. One end of the discharge hole 121 is connected to a valve 10 through a pipe.

[0023] The container bottle 4 has a glass bottle body 42 and a metal ring 43. The bottom of the metal ring 43 is welded to the middle panel 12, and the top is glued to the glass bottle body 42.

[0024] The top panel 13 has an upper mounting groove 131 at the bottom of one side, and the middle panel 12 has a lower mounting groove 122 at the top of one side corresponding to the upper mounting groove 131. Several sealing glass panes 8 are fixedly connected between the top panel 13 and the middle panel 12, and the sealing glass panes 8 are distributed around the top panel 13 and the middle panel 12. This keeps the container bottle 4 in a relatively sealed environment, which is beneficial to environmental protection and isolates it from the environment outside the measurement, thus minimizing the impact on the measurement results.

[0025] Two of the several sealed glass panes 8 are slidably mounted between the top panel 13 and the middle panel 12. The top of the sealed glass pane 8 is mounted in the upper mounting groove 131, and the bottom is mounted in the lower mounting groove 122.

[0026] The device body 1 also has a bottom panel 11 and connecting posts 14. The middle panel 12 is located between the bottom panel 11 and the top panel 13. The connecting posts 14 are distributed at the four corners of the bottom panel 11, the middle panel 12 and the top panel 13 to connect the panels together. The bottom of the bottom panel 11 is equipped with casters 2, the top of the middle panel 12 is equipped with a metal storage basket 3, the storage basket 3 is located on one side of the container bottle 4, and the top of the top panel 13 is equipped with a limiting block 132 for positioning the electronic density and temperature measuring instrument 7.

[0027] The electronic density temperature measuring instrument 7 is connected to the instrument discharge clamp 71 via wires. The bottom panel 11 is connected to the device discharge clamp 9 via wires. A metal sheet 123 extends downward from the bottom side of the middle panel 12 for the instrument discharge clamp 71 to clamp.

[0028] In one embodiment, how does the device calibrate the measuring instrument? Specifically, the electronic density temperature measuring instrument 7 is installed on the top panel 13, and its two sides are positioned against the limiting block 132. The instrument discharge clip 71 is clamped onto the metal plate 123 to form a passage between the electronic density temperature measuring instrument 7 and the device body 1. The device discharge clip 9 is clamped onto the electrostatic discharge post to release the static electricity of the entire device. The pipe extends into the receiving cavity 41 and fills the receiving cavity 41 with the oil sample to be measured. At this time, the receiving bottle 4 is in a semi-sealed environment. The oil sample passes through the filter screen 52 and enters the interior of the guide tube 5. The detection end of the electronic density temperature measuring instrument 7 is lowered by electric control. The detection end of the electronic density and temperature measuring instrument 7 is inserted into the guide tube 5 and comes into contact with the oil sample in the receiving cavity 41. The electronic density and temperature measuring instrument 7 is activated to measure the density and temperature of the oil sample in the receiving cavity 41. At the same time, a standard density meter and a standard thermometer are placed in the placement seat 6 and come into contact with the oil sample in the receiving cavity 41 to measure the temperature of the oil sample. The values ​​of the standard density meter and the standard thermometer are read and compared with the values ​​of the electronic density and temperature measuring instrument 7 to determine the error generated by the electronic density and temperature measuring instrument 7 and to calibrate it. After the measurement is completed, the valve 10 is opened to discharge the oil sample in the receiving cavity 41.

[0029] In summary, this device aligns the detection end of the electronic density and temperature measuring instrument 7, the guide tube 5, and the placement seat 6 with the receiving cavity 41, ensuring that the detection end of the electronic density and temperature measuring instrument 7, the standard density meter, and the standard thermometer can all measure the oil sample under the same conditions to calibrate the electronic density and temperature measuring instrument 7. This improves the accuracy of the test and avoids the problem that existing calibration containers are small in volume and have a fixed structure, making it impossible to simultaneously accommodate the electronic measuring instrument probe and manual measuring tools for measurement. By setting a guide tube 5, the detection end of the electronic density temperature measuring instrument 7 is placed inside the filter screen 52 for measurement, which can prevent the detection end of the electronic density temperature measuring instrument 7 from touching the inner wall of the container bottle 4 and breaking during the descent of the container cavity 41. By setting a sealed glass 8, a relatively sealed environment is formed between the top panel 13 and the middle panel 12, which is beneficial to environmental protection and has less impact on the measurement results. By setting up instrument discharge clamp 71 and device discharge clamp 9, static electricity in the device body 1 and electronic density and temperature measuring instrument 7 is released, avoiding the influence of static electricity on the oil sample and causing a fire, thus improving the safety during operation.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
