Description

Technical Field

[0001] This utility model relates to the field of sensor detection equipment technology, and in particular to an ultraviolet sensor testing device. Background Technology

[0002] In the field of water treatment, ultraviolet (UV) lamps are commonly used for sterilization and disinfection of water bodies, especially in ship ballast water treatment. UV-C ultraviolet lamps are used to treat ballast water to ensure that invasive alien species are not introduced into the ocean, thus protecting the ecological balance of the water area. For UV-C ultraviolet sterilization to be effective, the UV dose of the ultraviolet lamp must be greater than a certain value.

[0003] During operation, ultraviolet sensors are typically used to monitor the UV dose of the ultraviolet lamp in real time. To ensure the reliability of the equipment, the ultraviolet sensors must be inspected and calibrated regularly.

[0004] Currently, most methods for calibrating ultraviolet sensors involve disassembling the sensor and sending it back to the manufacturer for verification. The equipment used for verification also uses traditional mercury vapor lamps as the light source for the testing equipment, which cannot be taken to the site for sensor verification. This is time-consuming, labor-intensive, and inefficient. Utility Model Content

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0033] This application provides an ultraviolet sensor testing device to solve the technical problem of time-consuming and labor-intensive ultraviolet sensor calibration in related technologies.

[0034] As mentioned in the background section, for UV-C ultraviolet sterilization to be effective in water treatment, the UV dose of the ultraviolet lamp must be greater than a certain value. During operation, an ultraviolet sensor is needed to monitor the UV dose of the ultraviolet lamp in real time; therefore, the ultraviolet sensor plays a crucial role. To ensure the reliability of the equipment, the ultraviolet sensor must be inspected and calibrated regularly.

[0035] Currently, most methods for calibrating ultraviolet (UV) sensors involve disassembling the sensor and sending it back to the manufacturer for verification. The verification equipment uses traditional mercury vapor lamps as the light source. Because UV lamps have very low UV light luminous efficiency, they generally need to be at least 500W to be usable. Water cooling is required for stable operation, making the entire verification equipment large, complex, and cumbersome, making it difficult to bring directly to the field for sensor verification.

[0036] Based on the above description, one or more embodiments of this application provide an ultraviolet sensor testing device. The following describes the solution of the embodiments of this application in conjunction with the accompanying drawings.

[0037] like Figure 1 As shown in the embodiment of this application, the ultraviolet sensor testing device includes an assembly housing, a testing chamber, and a data processing module. The assembly housing houses a light source module 1, which provides ultraviolet light of a target wavelength. The testing chamber is located within the assembly housing, directly opposite the light source module 1. Two mounting sections are arranged side-by-side within the testing chamber; one mounting section connects to a reference ultraviolet sensor 2, and the other mounting section connects to an ultraviolet sensor 5 under test. The data processing module is located within the assembly housing and connected to both the reference ultraviolet sensor 2 and the ultraviolet sensor 5 under test to receive detection data from both sensors.

[0038] As can be seen from the above description, the ultraviolet sensor testing device in this embodiment integrates a light source module 1, a testing chamber, and a data processing module in an assembly housing. It synchronously tests the light source of the ultraviolet sensor 5 under test and the reference ultraviolet sensor 2. The data processing module receives the test data from the reference ultraviolet sensor 2 and the ultraviolet sensor 5 under test, thereby comparing whether the ultraviolet sensor 5 under test can work normally based on the test data. The working status of the ultraviolet sensor 5 under test can be tested directly on-site without sending it back to the manufacturer for special testing and calibration. The whole testing process is simple, convenient, and highly efficient.

[0039] In some embodiments, the light source module 1 includes a plurality of ultraviolet light-emitting diodes arranged in an array, wherein the radiation intensity of the plurality of ultraviolet light-emitting diodes is ≥100mW / cm². 2 .

[0040] The ultraviolet light-emitting diodes in the above scheme are also known as UV-C LED array lamps. Each ultraviolet light-emitting diode has a wavelength range of 100nm to 400nm, and the total power of multiple ultraviolet light-emitting diodes is 90W-110W.

[0041] Generally, ballast water systems require 40-80 mJ / cm³. 2 Dosage verification, therefore, not less than 100mW / cm 2 The radiation intensity can meet the full-scale calibration requirements of high-dose UV sensors. Compared with using mercury lamps as ultraviolet light sources, it can avoid the risk of mercury vapor toxicity and shorten the light source start-up time, making it easier to detect quickly.

[0042] It should be noted that, in some embodiments, the multiple ultraviolet light-emitting diodes arranged in an array in the light source module 1 can be further improved by installing a microlens array or a diffuse reflector to enhance the uniformity of ultraviolet light distribution within the detection chamber. The installation angle and position of the microlens array or diffuse reflector can be set with reference to structures or schemes for improving light source uniformity in related technologies, and will not be elaborated further in this embodiment.

[0043] like Figure 1 and Figure 2 As shown in the embodiment of this application, the mounting part is a threaded sleeve provided on the detection chamber. One of the threaded sleeves is threadedly connected to the reference ultraviolet sensor 2, and the other threaded sleeve is threadedly connected to the ultraviolet sensor 5 under test. The detection ends of the reference ultraviolet sensor 2 and the ultraviolet sensor 5 under test are positioned facing the light source module 1.

[0044] In the above scheme, the reference ultraviolet sensor 2 and the ultraviolet sensor under test 5 are installed side by side in the same chamber, which helps to ensure that both are under the same ultraviolet irradiation intensity, temperature, humidity and incident angle conditions, avoiding errors caused by environmental fluctuations in traditional time-division detection. Of course, the threaded sleeve should be arranged without affecting the probe of the ultraviolet sensor. Generally, the threaded sleeve is a through hollow cylinder, with one end facing the ultraviolet light emitted by the light source module 1, and the other end connected to the ultraviolet sensor through a threaded fit.

[0045] Here, the reference ultraviolet sensor 2 and the ultraviolet sensor under test 5 are ultraviolet sensors of the same model and specification. However, the reference ultraviolet sensor 2 is ensured to be in normal working condition, such as a brand new, unused ultraviolet sensor or an ultraviolet sensor that has been calibrated and is in normal working condition. The ultraviolet sensor under test 5 is an ultraviolet sensor that has been used for a period of time and has not been calibrated or tested.

[0046] In this embodiment of the application, the data processing module includes a data acquisition unit and a data processing unit connected to the data acquisition unit. The data acquisition unit is used to acquire and receive detection data from the reference ultraviolet sensor 2 and the ultraviolet sensor 5 under test. The data processing unit processes the comparison detection data and outputs the detection results.

[0047] Generally, the data processing module can use mature programmable controller components from relevant technologies. For example, by using an algorithm to compare the detection data of the reference ultraviolet sensor 2 and the ultraviolet sensor 5 under test, if the error of the compared detection data is large, it proves that the ultraviolet sensor 5 under test cannot work properly and needs to be replaced or repaired. If the error of the compared detection data is small, it proves that the ultraviolet sensor 5 under test is in good operating condition and can continue to be used. The judgment can be made flexibly according to the actual scenario.

[0048] like Figure 3 and Figure 4 As shown, in some embodiments, the ultraviolet sensor testing device further includes a power supply module 4 and a cooling fan. The power supply module 4 is disposed in the assembly housing and is connected to the data processing module, the light source module 1, the reference ultraviolet sensor 2, and the ultraviolet sensor 5 under test. A heat dissipation opening 7 is provided on the side of the assembly housing, and the cooling fan is used to output the heat inside the assembly housing to the outside through the heat dissipation opening 7.

[0049] In the above scheme, the power supply module 4 is used to supply power to the data processing module, the light source module 1, the reference ultraviolet sensor 2 and the ultraviolet sensor under test 5. Since the light source module 1 and the power supply module 4 will continuously generate heat during operation, the heat is dissipated by the cooling fan, which can effectively ensure the working environment of each component and help extend the life of the device.

[0050] Furthermore, the ultraviolet sensor testing device also includes a switch control component 6, which is connected to the power module 4 to adjust the on / off state of the power module 4. In addition, a display screen 3 is provided on the assembly housing, which is connected to the data processing module to display the processed data of the data processing module.

[0051] In some embodiments, the power module 4 is a rechargeable battery, and the mounting housing is provided with an external socket for connecting the power module 4. The external socket is used to connect to an external power source to charge the power module 4. Here, the external socket can be a common socket 8 or an aviation socket 9, and this embodiment is not absolutely limited to either.

[0052] like Figure 5 As shown in the embodiment of this application, the assembly housing is provided with a handle 10 to facilitate lifting the inspection device, and rollers are provided at the bottom of the assembly housing to facilitate moving the inspection device.

[0053] An exemplary testing step of the ultraviolet sensor testing device according to an embodiment of this application is as follows:

[0054] The power module 4 is turned on by the switch control unit 6. The reference ultraviolet sensor 2 and the ultraviolet sensor under test 5, which are arranged in parallel in the detection chamber, simultaneously sample the light source module 1. The sampling is performed for 30 seconds at irradiance of 40%, 60%, and 100%. The data processing module processes the above three sampling scenarios and obtains the test data, and determines that the ultraviolet sensor under test 5 is working normally.

[0055] It should be understood that although quantifiers such as "first," "second," etc., may be used herein to describe various units, these units should not be limited by these terms. These terms are used merely to distinguish one unit from another. For example, without departing from the scope of the exemplary embodiments, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit.

[0056] The directional terms such as "outer," "middle," and "inner" mentioned or potentially used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from the method of this application, and these improvements and additions should also be considered within the protection scope of this utility model.
