Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection device technology, specifically a detection device for copper conductors of flame-retardant cables in underground coal mines. Background Technology
[0002] Density testing is required for some metal raw materials purchased into the factory, finished products leaving the factory, or metal products to be sold in the commercial sector, in order to determine the material's composition. However, the testing methods for these substances mostly involve collecting a small amount of material and conducting physical and chemical index testing and analysis to determine the material's density composition.
[0003] Currently, existing instruments require manual sample tube installation, which can easily lead to testing errors and makes it inconvenient to test the density of samples. Therefore, we propose a testing device for copper conductors of flame-retardant cables in underground coal mines to solve the above problems. Utility Model Content

It features accurate testing, an integrated containerized pipeline to reduce leaks, and a uniform temperature field. It also solves the problems of manual sample tube installation, which can easily lead to testing errors and makes it inconvenient to test the density of samples.
[0006] (II) Technical Solution
[0007] To achieve the above-mentioned accuracy in testing, reduce air leakage points, and ensure uniform temperature difference, this utility model provides the following technical solution: a copper conductor testing device for flame-retardant cables in underground coal mines, comprising a base, a cylinder fixedly installed below the base, a through hole opened below the base, a cylinder rod that can be pushed upward through the through hole, a fixed base fixedly installed at the bottom inside the base, a sample tube base movably installed above the fixed base, a sample tube movably placed on the sample tube base, a connection port fixedly installed at the top inside the base, the connection port extending upward through the base and movably connected to a manifold pipeline module, the manifold pipeline module being cubic in shape, a pressure sensor movably installed on the right surface of the manifold pipeline module, and an air inlet device movably installed on the front surface, top surface, and rear surface of the manifold pipeline module.
[0008] Preferably, the pressure sensor is a high-precision imported silicon thin-film capacitive pressure sensor with an accuracy of 0.1% of the actual reading, which is better than 0.1% of the full range.
[0009] Preferably, the fixed base has a through hole to facilitate the upward ejection of the cylinder rod.
[0010] Preferably, the modular piping module adopts an integrated design, with no pipe joints between its valves.
[0011] (III) Beneficial Effects
[0012] Compared with the prior art, this utility model provides a detection device for copper conductors of flame-retardant cables in underground coal mines, which has the following advantages:
[0013] 1. This underground coal mine flame-retardant cable copper conductor testing device uses an integrated modular pipeline module and a cylinder. The integrated modular pipeline module is connected to the main unit. When the main unit detects the sample tube through the integrated modular pipeline module, the cylinder lifts it upward, causing the sample tube to move upward. The instrument automatically installs the sample tube to the connection port, making operation more convenient and avoiding testing errors caused by manual sample tube installation. Furthermore, the integrated modular pipeline eliminates pipeline joints between valves, reducing leakage points and ensuring a uniform temperature field.
[0014] 2. The copper conductor testing device for flame-retardant cables in underground coal mines, through the setting of sample tubes, directly uses the sample tubes as test chambers, which can effectively utilize the volume of the test chambers and significantly improve the testing accuracy. Sample tubes of different volumes can simultaneously meet the needs of micro-volume and large-volume sample loading, so as to improve the testing accuracy. 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1A testing device for copper conductors of flame-retardant cables in underground coal mines includes a base 1. A cylinder 2 is fixedly installed below the base 1. A through hole is provided below the base 1, through which the air rod in the cylinder 2 can be pushed upward. A fixed base 3 is fixedly installed at the bottom inside the base 1. The fixed base 3 has a through hole to facilitate the upward pushing of the air rod in the cylinder 2. A sample tube base 6 is movably installed above the fixed base 3. A sample tube 4 is movably placed on the sample tube base 6. A connection port 5 is fixedly installed at the top inside the base 1. A base 1 extends upward from the connection port 5 and is movably connected to a manifold pipeline module 7. The manifold pipeline module 7 is cubic in shape and adopts an integrated design, with no pipeline joints between its valves. A pressure sensor 9 is movably installed on the right surface of the manifold pipeline module 7. The pressure sensor 9 is a high-precision imported silicon thin-film capacitive pressure sensor with an accuracy of 0.1% of the actual reading, which is better than 0.1% of the full range. An air intake device 8 is movably installed on the front surface, top surface, and rear surface of the manifold pipeline module 7.
[0019] When using the instrument, first check whether each electronic component is working properly. Then connect the integrated tubing module 7 to the host and the cylinder 2 to the host. When a sample needs to be tested, first put the sample into the sample tube 4 and then into the sample tube base 6. At the same time, the cylinder 2 starts working, and the air rod inside the cylinder 2 moves upward, which drives the sample tube base 6 to move upward. The instrument automatically installs the sample tube 4 into the connection port 5, and then it can start working.
[0020] In summary, this underground coal mine flame-retardant cable copper conductor testing device, through the integrated cartridge pipeline module 7 and cylinder 2, connects the integrated cartridge pipeline module 7 to the main unit. When the main unit detects the sample tube 4 through the integrated cartridge pipeline module 7, the cylinder 2 lifts it upward, causing the sample tube 4 to move upward. The instrument automatically installs the sample tube 4 to the connection port 5, making operation more convenient and avoiding testing errors caused by manual installation of the sample tube 4. Furthermore, through the integrated cartridge pipeline 7, there are no pipeline joints between valves, reducing leakage points and ensuring a uniform temperature field.
[0021] Furthermore, by setting up sample tube 4, sample tube 4 can be directly used as a test chamber, which can effectively utilize the volume of the test chamber and significantly improve the test accuracy. Sample tubes of different volumes can simultaneously meet the needs of micro-volume and large-volume sample loading, so as to improve the test accuracy.
