[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] To address the issue that existing light sensors require compensation for light refraction on the water surface when used underwater, but the liquid flow velocity also affects refraction, leading to data inaccuracies; please refer to... Figure 1-3 The present invention provides the following solution:

[0019] A high-density water-resistant ultraviolet light sensor includes a sensor body 1, which includes a threaded tube shaft 101. One end of the threaded tube shaft 101 is equipped with a sealing end 102, and the other end of the threaded tube shaft 101 is equipped with a detection end 104. An insulating sleeve 103 is installed on the outside of the sealing end 102, and a circuit group 1031 is provided inside the insulating sleeve 103. The circuit group 1031 extends into the interior of the threaded tube shaft 101. A threaded sleeve 2 is installed on the outer surface of the threaded tube shaft 101, and an impeller 201 is provided on the inner side of the threaded sleeve 2. The impeller 201 is rotatably connected to the threaded sleeve 2 through a ball bearing 202.

[0020] In this embodiment, the transilluminator 1041 serves as an optical window that directly contacts the liquid being tested, allowing ultraviolet light to pass through. The photosensitive element 1042, which is tightly attached to its inner side, is responsible for receiving the ultraviolet light that passes through the liquid and converting it into a corresponding weak electrical signal.

[0021] A transparent sheet 1041 is mounted on the outer surface of the detection end 104. A photosensitive element 1042 is attached and fixed to the inner side of the transparent sheet 1041. The photosensitive element 1042 is connected to the threaded tube shaft 101 by screws. A wiring tube 1044 is mounted above the photosensitive element 1042. The other end of the wiring tube 1044 is connected to the conversion module 1045. The conversion module 1045 is electrically connected to the circuit group 1031. An anti-interference sleeve 1043 is mounted on the outer side of the wiring tube 1044. The anti-interference sleeve 1043 is attached to the inner wall of the threaded tube shaft 101. An indicator light 1046 for displaying the working status is mounted on one side of the anti-interference sleeve 1043. A sensor assembly is installed inside the ball bearing 202.

[0022] In this embodiment, when the sensor is placed in a flowing liquid, the liquid flow impacts the impeller 201 inside the screw sleeve 2. The impeller 201 begins to rotate under the action of fluid power, and its rotation speed is positively correlated with the liquid flow rate. The impeller 201 achieves smooth rotation with low friction through the ball bearing 202. The ball bearing 202 integrates a magnetic sensitive element, which cooperates with the magnet on the impeller 201 to accurately convert the impeller rotation speed into a series of pulse electrical signals. The faster the impeller rotates, the higher the pulse frequency. Using the real-time collected flow rate data, the refractive compensation coefficient corresponding to the current flow rate is calculated. Subsequently, this coefficient is used to perform real-time and dynamic mathematical correction on the original light intensity measurement value, thereby eliminating the optical measurement error introduced by the liquid flow.
