Description

Technical Field

[0001] This utility model relates to the field of test tube turbidity detector technology, and in particular to a test tube turbidity detector. Background Technology

[0002] A test tube turbidity detector is an instrument used to measure the turbidity of water in a test tube. Its working principle is mainly based on the principle of light scattering or transmission by turbid liquid. It assesses the turbidity of water by measuring the degree of light scattering by suspended or dissolved matter in the water.

[0003] The existing test tube turbidity detector is a one-piece hollow design. Although test tubes can be inserted into it, there are still some shortcomings in its use. For example, in addition to inserting test tubes, it is not possible to directly add the liquid to be tested into it. At the same time, its plastic shell and one-piece structure also result in poor stability and are very inconvenient to use.

[0004] To address the aforementioned issues, this application proposes a test tube turbidity detector. Utility Model Content

[0005] This invention provides a test tube turbidity detector to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, this utility model provides a test tube turbidity detector, including a detector body, an infrared transceiver module fixedly installed inside the detector body, a test tube holder fixedly connected to the top of the detector body, and a groove opened on the top of the test tube holder, the groove being located directly above the infrared transceiver module.

[0007] Preferably, the test tube holder is made of polycarbonate rod.

[0008] Preferably, a wiring terminal is fixedly connected to one side of the detector body.

[0009] Preferably, the detector body has multiple mounting holes at its bottom edge.

[0010] Compared with related technologies, the test tube turbidity detector provided by this utility model has the following beneficial effects:

[0011] By installing a test tube holder on the detector body, the groove on the test tube holder can not only be used to insert test tubes, but also to directly add the liquid to be tested, making it more convenient to use. At the same time, the test tube holder can also be customized in different sizes according to needs, that is, the groove size can be customized to adapt to different types of test tubes. In addition, the outer shell of the detector body is made of stainless steel, which makes the overall stability better. Attached Figure Description

[0017] Implementation examples, by Figure 1-4 The present invention includes a detector body 1, an infrared transceiver module 2 fixedly installed inside the detector body 1, and a test tube holder 5 fixedly connected to the top of the detector body 1. The test tube holder 5 has a groove 6 on its top, which is located directly above the infrared transceiver module 2. Turbidity is detected by the infrared transceiver module 2 based on the infrared transceiver principle. It has the characteristics of strong anti-interference, high accuracy, and fast response. The inner diameter of the groove 6 is 30.0-30.1mm, which is suitable for test tubes with an outer diameter of less than 30mm. At the same time, the size of the test tube holder 5 and the groove 6 on the test tube holder 5 can also be customized according to the actual situation so as to adapt to the use of test tubes of different sizes and models.

[0018] The test tube holder 5 is made of polycarbonate rods, also known as PC rods, which are engineering plastic products extruded from PC resin. Polycarbonate (PC) rods have good mechanical properties, impact resistance, and weather resistance. They maintain stable physical properties within the range of -40℃ to +120℃, are dimensionally stable when heated, and are lightweight. The weight of a PC sheet is half that of glass of the same thickness. They also have excellent electrical and dielectric properties, good light transmittance, and a light transmittance of 87% for a 3mm transparent sheet. They have high light transmittance, transparency, low haze, and a light transmittance of up to 93%. These high light transmittance and other characteristics ensure that they do not affect the operation of the infrared transceiver module 2.

[0019] A terminal block 3 is fixedly connected to one side of the detector body 1. The terminal block 3 can be used to connect wires to make electrical connections with the equipment terminal for use.

[0020] The detector body 1 has multiple mounting holes 4 at its bottom edge. By passing screws through the mounting holes 4, the detector can be fixed to the cross arm, further improving stability.

[0021] Working principle:

[0022] In use, the liquid to be tested is placed in test tube 7, and then the bottom of test tube 7 is inserted into the groove 6 on test tube holder 5. Then, the turbidity of the liquid in test tube 7 is detected by the infrared transceiver module 2 in the detector body 1 through the test tube holder 5 using the infrared transceiver principle. Alternatively, liquid can be directly injected into the groove 6 for turbidity detection.
