Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a water quality detection filter module. Background Technology

[0002] In the field of water quality testing, spectrophotometry has become the mainstream technique for determining key indicators such as chemical oxygen demand (COD), ammonia nitrogen, and total phosphorus due to its advantages of convenient operation and high detection accuracy. The core principle of this method is to utilize the interaction between a specific wavelength of light beam and the target substance in the water sample, calculating the substance concentration through the light absorption or transmission characteristics. The filter module, as the core component for selecting the wavelength of the light beam, directly determines the accuracy and efficiency of the detection results.

[0003] The aforementioned existing technical solutions have the following drawbacks: they emit only one type of light beam, which cannot provide a specific wavelength detection light beam for different colors of water. Utility Model Content

[0004] The purpose of this invention is to provide a water quality detection filter module to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A water quality detection filter module includes a frame. A servo motor is fixedly mounted on the left side of the frame. A through-hole penetrating the frame is provided on the left side of the frame. A bearing is fixedly mounted inside the right end of the through-hole. A rotating shaft is fixedly mounted inside the frame. The right end of the rotating shaft passes through the bearing. The left end of the rotating shaft is fixedly connected to the output shaft of the servo motor, and the axis of the rotating shaft is collinear with the axis of the servo motor drive shaft. A turntable is sleeved on the left end of the rotating shaft. Multiple sleeves are axially distributed on the right side of the turntable. A filter is fixedly mounted inside each sleeve. A light-transmitting hole is provided on the right side of the frame to prevent light beams transmitted through the filter.

[0007] By adopting the above technical solution, the turntable is set into a crescent shape during use. Five sleeves are arranged clockwise on the right side of the turntable. The center of each sleeve has a through-hole. Five light sources, each corresponding to a sleeve, are then placed on the turntable. The light beam emitted by the light source passes through the through-hole of the sleeve from left to right. After passing through the filter inside the sleeve, the light beam is filtered to remove impurities, allowing only the desired wavelength of light to enter the light-transmitting hole. When the wavelength needs to be changed, a servo motor is driven to rotate. The servo motor rotates 45 degrees to change the wavelength.

[0008] In a further embodiment, the sleeve has a through-hole at its center, and the axis of the sleeve is parallel to the axis of the rotating shaft. The right side of the turntable has a receiving groove corresponding to the sleeve, and a light source is fixedly installed inside each receiving groove.

[0009] By adopting the above technical solution, the light source is used to provide light to the shaft hole of the sleeve, and the light source is an LED lamp.

[0010] In a further embodiment, a ring integrally formed with the sleeve is provided at the inner right end of the sleeve, and a bracket is fixedly installed inside the sleeve. The bracket is used to press the filter against the left end face of the ring.

[0011] By adopting the above technical solution, the bracket is a cylindrical structure with a through-hole at the center. The through-hole is used to avoid the path of the light beam. The bracket is used to limit the position of the filter in the shaft hole of the sleeve and to cooperate with the ring to firmly hold the filter against the right end of the sleeve.

[0012] In a further embodiment, a semi-circular groove is provided at the center of the left end of the rotating shaft, and the output shaft of the servo motor is provided with an extension end that passes through a through hole from left to right, the shape of the extension end being adapted to the semi-circular groove.

[0013] By adopting the above technical solution, a spline-like connection structure is completed between the motor output shaft and the rotating shaft to prevent relative rotation between the motor output shaft and the rotating shaft.

[0014] In a further embodiment, both the front and rear ends of the frame are completely open.

[0015] The above technical solution is used to provide a heat dissipation channel and a channel for installing wiring harnesses.

[0016] In a further embodiment, each of the four rear corners of the frame is provided with an extension block protruding from the frame, and each extension block is provided with a through mounting hole at its center.

[0017] The above technical solution is used to install this module on the device.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The light beam emitted by the light source passes through the shaft hole of the sleeve from left to right. After the light beam passes through the filter inside the sleeve, the impurities of the light are removed, so that only the light of the required wavelength enters the light transmission hole. When the wavelength needs to be changed, the servo motor is driven to rotate. The servo motor rotates 45 degrees to change the wavelength. Attached Figure Description

[0028] Specific implementation process: When in use, the turntable is set to a crescent shape, and five sleeves are arranged clockwise on the right side of the turntable. The center of each sleeve has a through-hole. Then, five light sources corresponding to the sleeves are set on the turntable. The light beam emitted by the light source passes through the through-hole of the sleeve from left to right. After the light beam passes through the filter inside the sleeve, the impurities in the light are removed, so that only the light of the required wavelength enters the light transmission hole. When the wavelength needs to be changed, the servo motor is driven to rotate. Every 45 degrees of rotation of the servo motor changes the wavelength. The filter can remove all unwanted light emitted by the light source, achieving a filtering effect. This device is the light source emission module in the water quality analyzer, used to provide the water quality analyzer with a detection beam of a specified wavelength.
