Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a small cross-section DC copper conductor tester. Background Technology

[0002] Density is a measure of mass within a specific volume. Density equals the mass of an object divided by its volume and can be represented by the symbol ρ. In the International System of Units (SI) and Chinese legal units of measurement, the unit of density is kilograms per cubic meter, with the symbol kg / m³.

[0003] Because existing density testing devices are cumbersome to operate, we propose a small-section DC copper conductor tester that uses an integrated metal pipeline and is a fully automatic testing instrument that uses the gas displacement method to detect the true density of liquids (non-volatile and non-corrosive) and solids. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a small-section DC copper conductor tester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A small cross-section DC copper conductor tester includes two symmetrically arranged bases. A support base is fixedly installed on the top of each base, and the same tester body is fixedly installed on the top of both support bases. A control system is mounted on the tester body. A connecting plate is fixedly installed on one side of the tester body, and a wireless mouse is mounted on the connecting plate. The mouse works in conjunction with the control system. A fixed cavity is formed on the tester body. An electronic scale is mounted on one side of the tester body, and a sample box is mounted on the electronic scale. The sample box contains a sample and a fan. A PU gas pipe is mounted on the fan, and one end of the PU gas pipe extends into the fixed cavity and is equipped with multiple helium pressure reducing valves. A helium tank containing helium is located inside the fixed cavity.

[0007] Preferably, the PU air pipe is equipped with a pressure gauge, which is matched with the PU air pipe.

[0008] Preferably, the other end of the PU gas pipe extends to the outside of the fixed cavity.

[0009] Preferably, the number of helium pressure reducing valves is two to three.

[0010] Preferably, the tester body has a circular hole, through which the PU gas pipe extends into the fixed cavity. A sealing ring is provided on the side wall of the circular hole, and the PU gas pipe is sealed to the circular hole through the sealing ring.

[0011] The beneficial effects of the small cross-section DC copper conductor tester described in this utility model are as follows:

[0012] We can obtain the mass of the extracted sample using an electronic scale. The sample is then drawn into a helium tank, from which helium gas is expelled. The volume of the expelled helium gas can be obtained using a pressure gauge, and this volume is the same as the volume of the sample.

[0013] This invention has a simple structure and is easy to use, making it convenient for people to test the density of samples. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-2 A small cross-section DC copper conductor tester includes two symmetrically arranged bases 1. A support base 2 is fixedly installed on the top of each base 1. A single tester body 3 is fixedly installed on the top of each support base 2. A control system 9 is mounted on the tester body 3. A connecting plate 13 is fixedly installed on one side of the tester body 3. A wireless mouse 14 is mounted on the connecting plate 13 and works in conjunction with the control system 9. A fixed cavity 4 is formed on the tester body 1. An electronic scale 10 is mounted on one side of the tester body 3. A sample box 11 is mounted on the electronic scale 10. The sample box 11 contains a sample and an exhaust fan 12. A PU gas pipe 5 is mounted on the exhaust fan 12. One end of the PU gas pipe 5 extends into the fixed cavity 4 and is equipped with multiple helium pressure reducing valves 6. A helium tank 8 is located inside the fixed cavity 4, containing helium gas.

[0019] In this invention, a pressure gauge 7 is provided on the PU gas pipe 5. The pressure gauge 7 works in conjunction with the PU gas pipe 5. By setting the pressure gauge 7, the volume of the discharged inert gas can be obtained well, thereby obtaining the volume of the sample.

[0020] In this invention, the other end of the PU gas pipe 5 extends to the outside of the fixed cavity 4, thereby effectively discharging the inert gas.

[0021] In this invention, the number of helium pressure reducing valves 6 is two to three.

[0022] In this invention, the main body 3 of the testing instrument is provided with a round hole, and the PU gas pipe 5 extends into the fixed cavity 4 through the round hole. A sealing ring is provided on the side wall of the round hole, and the PU gas pipe 5 is sealed to the round hole through the sealing ring. The sealing ring can effectively ensure the airtightness of the device, thereby ensuring the accuracy of the density.

[0023] In this invention, the mass of the sample can be calculated using an electronic scale 10. The sample is then extracted into a helium chamber 8, where helium gas is expelled. The volume of the expelled helium gas is obtained using a pressure gauge 7. Since the volume of the expelled helium gas is the same as the volume of the sample, the volume of gas displaced by the sample in the test chamber can be calculated using Archimedes' principle and the ideal gas law: PV = nRT. This allows for the accurate measurement of the sample's skeletal volume (including closed pores). The true density value is then calculated using the density equation: ρ = M / V. The instrument is equipped with a Windows operating system 9 industrial control computer, allowing for both host operation and external computer operation via serial port. Both operation modes are fully automatic, requiring no manual intervention, and automatically generate and save test results. The dual control system provides users with a more convenient operating method, allowing users to switch between operating modes as needed. Both systems offer full voice prompts, facilitating user operation.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
