Detailed Implementation

[0019] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0020] To better understand the technical solution of this application, the underwater ultraviolet lamp testing device of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementation methods can be combined with each other.

[0021] See Figure 1 , Figure 2 and Figure 3 As shown, this application provides an underwater ultraviolet lamp testing device 10, which includes a main control system 19 and an experimental system 11 arranged underwater. The main control system 19 includes a master controller 20, which can be an industrial computer. The main control system 19 is located on the water and can be mounted on a raft moored in a bay. The experimental system 11 can be located at the bottom of the raft moored in the bay and submerged in seawater.

[0022] The experimental system 11 includes a mounting bracket 12, an ultraviolet lamp 13, and multiple hanging plates 14. The ultraviolet lamp 13 can be a UVC ultraviolet lamp with a wavelength of 260nm~275nm. In this embodiment, the wavelength of the ultraviolet lamp 13 is 265nm. The ultraviolet lamp 13 and the multiple hanging plates 14 are mounted on the mounting bracket 12. The ultraviolet lamp 13 extends vertically on the mounting bracket 12. The multiple hanging plates 14 are arranged at intervals around the central axis of the ultraviolet lamp 13. At least some of the hanging plates 14 can be located within the irradiation range of the ultraviolet lamp 13, and at least some of the hanging plates 14 can be located outside the irradiation range of the ultraviolet lamp 13. The multiple hanging plates 14 located within the irradiation range of the ultraviolet lamp 13 are concentrically arranged with the ultraviolet lamp 13, so that the multiple hanging plates 14 can uniformly receive the ultraviolet radiation from the ultraviolet lamp 13.

[0023] UV lamp 13 includes lamp body 18 (e.g. Figure 4 (As shown) and at least three lamp panels, the at least three lamp panels being arranged at intervals along the circumference of the lamp body 18. The at least three lamp panels can be arranged at uniform intervals along the circumference of the lamp body 18. Multiple hanging pieces 14 exist within the illumination range of each lamp panel.

[0024] In one embodiment, for the hanging pieces 14 within the illumination range of different lamp panels, the distance from each hanging piece 14 to its corresponding lamp panel is different. Furthermore, the distances from multiple hanging pieces 14 within the illumination range of the same lamp panel to that lamp panel can be the same or different.

[0025] In another embodiment, for multiple hanging pieces 14 within the illumination range of the same lamp panel, at least two hanging pieces are at different distances from the lamp panel.

[0026] In this embodiment, the ultraviolet lamp 13 includes three lamp plates evenly spaced along the circumference of the lamp body 18. Multiple hanging plates 14 include a first hanging plate 15 within the illumination range of the first lamp plate, a second hanging plate 16 within the illumination range of the second lamp plate, and a third hanging plate 17 within the illumination range of the third lamp plate. The first hanging plate 15, the second hanging plate 16, and the third hanging plate 17 are respectively located within the illumination range of the three lamp plates. The number of first hanging plates 15, second hanging plates 16, and third hanging plates 17 can be multiple. The distances from the first hanging plate 15, the second hanging plate 16, and the third hanging plate 17 to their respective lamp plates are all different.

[0027] In one embodiment, the mounting plate 14 may extend at an angle from bottom to top, away from the ultraviolet lamp 13. In this embodiment, the angle between the mounting plate 14 and the horizontal plane of the mounting bracket 12 is 45°, which ensures that the mounting plate 14 is effectively irradiated.

[0028] In one embodiment, the plurality of hanging pieces 14 located within the irradiation range of the ultraviolet lamp 13 further include a fourth hanging piece 31, which may be located on the side of the third hanging piece 17 away from the ultraviolet lamp 13.

[0029] The main controller 20 is connected to at least three lamp panels. The main controller 20 is used to control the light emission brightness and light emission time of each lamp panel so that the ultraviolet light irradiation conditions received by the multiple hanging pieces 14 within the irradiation range of different lamp panels are different.

[0030] The underwater ultraviolet lamp testing device 10 provided in this application can determine the effective working distance, effective luminous intensity, and effective luminous time of the ultraviolet lamp 13 in the underwater environment by determining the degree of biological attachment of the hanging piece 14 within the irradiation range of different lamp plates, thereby determining the effective working conditions of the ultraviolet lamp 13. The testing method is simple and reliable.

[0031] In one embodiment, the experimental system 11 further includes a camera 21 mounted on a mounting bracket 12 and facing the ultraviolet lamp 13 and multiple hanging plates 14. In this embodiment, the camera 21 is located at the top of the mounting bracket 12, the ultraviolet lamp 13 and multiple hanging plates 14 are located at the bottom of the mounting bracket 12, and the camera 21 faces downward. An antifouling film can be provided on the outer surface of the camera 21. The lens of the camera 21 can also be protected from marine organism adhesion and accumulation by mechanical scraping. Multiple cameras 21 can be used to capture multiple images of multiple hanging plates 14 from multiple perspectives.

[0032] The main controller 20 is connected to the camera 21 via a waterproof cable. The main controller 20 acquires bio-attachment images of multiple hanging plates 14 captured by the camera 21 and sends these images to a terminal device upon receiving a remote transmission command. The bio-attachment images demonstrate the bio-attachment status of the multiple hanging plates 14. This allows the experimental system 11 to monitor the bio-attachment status of multiple hanging plates 14 in real time without needing to exit the water, avoiding the impact of frequent retrieval and recording processes on test results and significantly reducing manual workload. Simultaneously, the bio-attachment images can be automatically analyzed to determine the performance score of the ultraviolet lamp 13. The more organisms on the hanging plates 14 within the irradiation range of the ultraviolet lamp 13, the lower the performance score of the ultraviolet lamp 13. When multiple hanging plates 14 exist within the irradiation range of the ultraviolet lamp 13, the average score of each hanging plate 14 can be taken.

[0033] The main controller 20 can push bio-attachment images to cloud storage, or it can store bio-attachment images locally, allowing terminal devices to actively retrieve the stored data. The main controller 20 can also store bio-attachment images locally and then actively push them to terminal devices; the specific data transmission and reception methods are not limited in this application.

[0034] In one embodiment, the main controller 20 is configured to turn on the camera 21 at set intervals to capture images of bio-attachment on multiple patches 14 and save the bio-attachment images. After saving the bio-attachment images, the camera 21 is turned off.

[0035] In one embodiment, the intersection of the normals of the hanging plates 14 is located at the midpoint of the line connecting the ultraviolet lamp 13 and the camera 21. This ensures that while multiple hanging plates 14 are effectively irradiated, the camera 21 can also observe the biological attachment status of the multiple hanging plates 14, resulting in good observation results.

[0036] In one embodiment, the center point of the hanging plate 14 and the center point of the lamp panel are on the same horizontal plane, which ensures that the hanging plate 14 is effectively irradiated by the ultraviolet lamp 13.

[0037] In one embodiment, the mounting bracket 12 includes a mounting base 22, a mounting top plate 23, and a support column 24. An ultraviolet lamp 13 and multiple hanging plates 14 are disposed on the mounting base 22. The mounting base 22 can be rectangular, circular, fan-shaped, or other shapes, and this application is not limited thereto. The ultraviolet lamp 13 is located at the center of the mounting base 22 and can be fixed to the mounting base 22 using mechanical rigid connections such as stainless steel cable ties, bolts, rivets, or clips. The camera 21 is disposed on the mounting top plate 23.

[0038] Support columns 24 are located on the outside of the multiple hanging plates 14, with one end connected to the mounting top plate 23 and the other end connected to the mounting base 22. There can be at least two support columns 24, arranged at intervals around the central axis of the ultraviolet lamp 13. The support columns 24 can be located outside the irradiation range of the ultraviolet lamp 13. In this way, while ensuring that the multiple hanging plates 14 are effectively irradiated, they are also fully exposed to seawater, ensuring the observation effect.

[0039] In one embodiment, the mounting base 22 has multiple arc-shaped grooves 25 extending around the central axis of the ultraviolet lamp 13, corresponding to the direction of each lamp panel. Each arc-shaped groove 25 has a different radius of curvature, meaning each arc-shaped groove 25 is at a different distance from the central axis of the ultraviolet lamp 13. The central angle of the arc-shaped groove 25 can be equal to the illumination angle of the lamp panel. In this embodiment, the central angle of the arc-shaped groove 25 can be 120°.

[0040] Multiple hanging plates 14 are detachably disposed in the arc-shaped groove 25. Multiple hanging plates 14 can be connected to different arc-shaped grooves 25. The installation position of multiple hanging plates 14 is defined by the arc-shaped groove 25. This method of determining the position of multiple hanging plates 14 is simple and facilitates the fixing of multiple hanging plates 14. Thus, the hanging plates 14 can be placed at different angles and distances of the ultraviolet lamp 13 for bio-attachment testing.

[0041] In one embodiment, the experimental system 11 includes a mounting base 26, which includes a flat portion 27 and a bent portion 28. The bent portion 28 is connected to the flat portion 27 and can be integrally formed with the flat portion 27. The bent portion 28 extends obliquely from the flat portion 27 in a direction away from the UV lamp 13. The mounting base 26 can be formed by bending a sheet metal part. A hanging piece 14 is connected to the side of the bent portion 28 near the UV lamp 13, and the flat portion 27 is connected to the mounting base 22. The hanging piece 14 is connected to the side of the bent portion 28 near the UV lamp 13 by screws, and the flat portion 27 is connected to the mounting base 22 by bolts. This makes the connection of the hanging piece 14 more stable, thus enabling it to withstand the impact of ocean currents.

[0042] In one embodiment, the mounting base 26 and the mounting plate 14 are isolated by an insulating bushing to prevent electrochemical corrosion. When cathodic protection testing is required, one or more mounting plates 14 can be connected to a potentiometer.

[0043] See Figure 2 and Figure 4As shown, in one embodiment, the ultraviolet lamp 13 includes a connection port 29 located on the lamp body 18. The connection port 29 is connected to the main controller 20. The connection port 29 can be connected to the main controller 20 via a waterproof cable. The mounting base 22 has multiple hollow sections 30. The waterproof cable connected to the connection port 29 of the ultraviolet lamp 13 can extend from below the ultraviolet lamp 13, pass through the hollow sections 30, extend upwards, and connect to the main controller 20. This reduces the weight of the underwater ultraviolet lamp testing device 10, achieving structural lightweighting and reducing experimental costs. At the same time, the hollow sections 30 reduce the lateral force load caused by ocean current impact, improving the overall anti-overturning capability.

[0044] See Figure 5 As shown, in one embodiment, the underwater ultraviolet lamp testing device 10 further includes a power supply system 32, which can provide uninterrupted power to the underwater ultraviolet lamp testing device 10. The power supply system 32 includes a power connection terminal 33, a solar panel 34, a power switching module 35, and a battery pack 36. The power connection terminal 33 is used to connect to an external power source. The external power source can be AC ​​mains power or a fuel cell. The battery pack 36 may include multiple batteries connected in series. The power connection terminal 33 and the solar panel 34 are connected to the battery pack 36 through the power switching module 35. When the power switching module 35 is in a first state, the external power source supplies power to the battery pack 36, thus enabling power supply to the battery pack 36 in case of damage to the solar panel 34. When the power switching module 35 is in a second state, the solar panel 34 supplies power to the battery pack 36, thereby saving energy.

[0045] The main controller 20 is used to switch the power switching module 35 from a first state to a second state when the voltage of the battery pack 36 is lower than a first preset voltage value for a preset duration. In this embodiment, the first preset voltage value can be 24V, and the duration can be 30 minutes. This allows the system to switch to an external power source to power the battery pack 36 when the voltage is too low, protecting the battery pack 36 and improving the safety of the underwater ultraviolet lamp testing device 10. The main controller 20 is also used to switch the power switching module 35 from the second state to the first state when an external power outage is detected, thereby ensuring the continuity of power supply.

[0046] The underwater ultraviolet lamp testing device 10 of this application can be powered by solar energy, as well as by conventional or unconventional outdoor energy sources such as wind energy, tidal energy, and fuel cells. This application does not impose any restrictions.

[0047] In one embodiment, the power switching module 35 includes a DC contactor 37 and an AC contactor 38. The main circuit of the DC contactor 37 is connected in series with the solar panel 34, and the main circuit of the AC contactor 38 is connected in series with the power connection terminal 33. The DC contactor 37 and the AC contactor 38 are interlocked to prevent the solar panel 34 from simultaneously supplying power to the battery pack 36 with an external power source.

[0048] In one embodiment, the power supply system 32 further includes a solar controller 39 and a reverse diode module 40. The reverse diode module 40 is connected between the solar controller 39 and the solar panel 34 to prevent current from flowing back to the solar panel 34. The solar controller 39 can be connected to the main controller 20 and is used to output data such as the voltage, current, battery voltage, and charging / discharging power of the solar panel 34 to the main controller 20.

[0049] In one embodiment, the power supply system 32 further includes a mains power supply leakage current protector 41, which is connected between the power connection terminal 33 and the power switching module 35 and can play a protective role.

[0050] In one embodiment, the power supply system 32 further includes a battery charger 42, which is connected between the power connection terminal 33 and the power switching module 35 and can convert AC power into DC power to supply the battery pack 36.

[0051] In one embodiment, the main control system 19 further includes a switching power supply 43, which is connected to the output terminal of the battery pack 36.

[0052] In one embodiment, the main control system 19 further includes a fuse 44, which is connected between the switching power supply 43 and the main controller 20 and can protect the main controller 20.

[0053] In one embodiment, the main controller 20 outputs a pulse signal with a duty cycle corresponding to the input brightness value to a control switch connected in series with the lamp panel whose brightness is to be adjusted. The lamp beads of the lamp panel and the control switch are connected in series to the power supply system 32. When the pulse signal is either low or high, the pulse signal closes the control switch, and the power supply system 32 supplies power to the lamp panel. When the pulse signal is either low or high, the pulse signal opens the control switch, and the power supply system 32 does not supply power to the lamp panel. The duty cycle of the pulse signal corresponds to the target brightness value. Thus, the brightness and duration of the lamp panel can be adjusted by adjusting the duty cycle of the pulse signal. The input brightness value can be a brightness value input by the user or a target brightness value determined by the main controller 20.

[0054] In one embodiment, the ultraviolet lamp 13 includes at least three light intensity sensors, each corresponding to a lamp panel. A main controller 20 is connected to the at least three light intensity sensors. The main controller 20 acquires the illumination intensity of the corresponding lamp panels collected by the at least three light intensity sensors, and identifies a target lamp panel with abnormal illumination intensity based on the illumination intensity of the at least three lamp panels. A target brightness value for the target lamp panel is determined based on the illumination intensity of the other lamp panels. A pulse signal with a duty cycle corresponding to the target brightness value is output to a control switch connected in series with the target lamp panel. This ensures that the illumination intensity of at least three lamp panels is consistent when individually verifying the effective operating distance or effective emission time.

[0055] See Figure 6 As shown, in one embodiment, the underwater ultraviolet lamp testing device 10 further includes an electrical control cabinet 45 (e.g., Figure 1 As shown, the main control system 19 includes a temperature sensor and a humidity sensor, and is located inside the electrical control cabinet 45. The main controller 20 determines the dew point temperature based on the cabinet temperature collected by the temperature sensor and the cabinet humidity collected by the humidity sensor. Based on the dew point temperature, it determines whether there is a risk of condensation. If there is a risk of condensation, an abnormal alarm message is generated and sent to the terminal device. The abnormal alarm message can be a warning email.

[0056] The determination of whether there is a risk of condensation based on the dew point temperature includes: comparing the lowest temperature among the temperatures of each component in the electrical control cabinet 45 and the temperature of the inner wall of the electrical control cabinet 45 with the dew point temperature. If the lowest temperature is not greater than the dew point temperature, then there is a risk of condensation.

[0057] In one embodiment, the main control system 19 further includes a communication device. In this embodiment, the communication device can be a router 46. The main controller 20 is connected to the communication device, and the main controller 20 is used to send abnormal alarm information to the terminal device through the communication device. The communication device supports networking methods such as 4G, 5G, satellite, fiber optic, and wired connections; this application does not impose any limitations.

[0058] In one embodiment, the main controller 20 generates an abnormal alarm message and sends it to the terminal device when the light intensity sensor detects that the light intensity of the corresponding lamp panel is lower than a preset light intensity value. This allows for timely intervention when the light intensity of the lamp panel is low, ensuring the stable operation of the underwater ultraviolet lamp testing device 10.

[0059] In one embodiment, the power supply system 32 includes an ambient light sensor and a solar controller 39 connected to the solar panel 34. The solar controller 39 is used to send a fault signal to the main controller 20 when the ambient light detected by the ambient light sensor is greater than a preset ambient light and the photovoltaic output voltage of the solar panel 34 is lower than a second preset voltage value. The main controller 20 is used to generate abnormal alarm information upon receiving the fault signal and send the abnormal alarm information to the terminal device.

[0060] In one embodiment, the main control system 19 further includes a multi-channel circuit breaker 47 connected to the main controller 20. The input terminal of the multi-channel circuit breaker 47 is connected to the switching power supply 43, and the output terminal of the multi-channel circuit breaker 47 is connected to the router 46, the temperature sensor, the humidity sensor, the ultraviolet lamp 13, and the camera 21, respectively. The main controller 20 can realize the connection and disconnection between the router 46, the temperature sensor, the humidity sensor, the ultraviolet lamp 13, and the camera 21 and the switching power supply 43 through the multi-channel circuit breaker 47. The router 46, the temperature sensor, the humidity sensor, the ultraviolet lamp 13, and the camera 21 can be turned off individually to achieve the purpose of saving power.

[0061] In one embodiment, the main controller 20 is used to control the multi-channel circuit breaker 47 to perform a preset number of restart operations when an abnormal state is detected. If the abnormal state is not eliminated, the main controller 20 controls the multi-channel circuit breaker 47 to cut off the power supply to the router 46, temperature sensor, humidity sensor, ultraviolet lamp 13 and camera 21.

[0062] The main controller 20 communicates with the router 46, temperature sensor, humidity sensor, ultraviolet lamp 13, camera 21, multi-channel circuit breaker 47 and solar controller 39 through serial port, network cable, RS485, wireless WIFI and other means.

[0063] In one embodiment, the main controller 20 can set the switching frequency of the router 46, causing the router 46 to intermittently turn on and off according to a preset switching frequency. The main controller 20 is used to send bioattachment images and / or data to the terminal device when the router 46 is on, and to turn off the router 46 after sending the bioattachment images and / or data to the terminal device. The main controller 20 can analyze the bioattachment images and output data, which is then sent to the terminal device. Alternatively, the main controller 20 can send bioattachment images to the terminal device for analysis.

[0064] In one embodiment, before the main controller 20 sends the bio-attachment image and / or data to the terminal device, the main controller 20 is also configured to generate an abnormal alarm message and send the abnormal alarm message to the terminal device when an abnormal state is detected.

[0065] In one embodiment, the main controller 20 is also used to keep the router 46 on when an abnormal state is detected. When the router 46 is on, it can communicate remotely with the terminal device, thereby remotely controlling the underwater ultraviolet lamp testing device 10. In this way, the images and / or data of biological attachment can be saved in a timely manner, which significantly improves the storage security.

[0066] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
