Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a colorimetric device for detecting chromaticity of drinking water. Background Art

[0002] Visual colorimetry is a conventional method for determining concentration, limit, and color. Due to its simple equipment, easy operation, high sensitivity, and the fact that it does not require the colored solution to strictly obey Beer's law, it is widely used in routine analytical testing where accuracy requirements are not high.

[0003] Currently, water colorimetry primarily relies on visual colorimetry, where a water sample is placed in a 50mL colorimetric tube and visually compared with a platinum-cobalt standard colorimetric column to determine the sample's color. However, this method relies primarily on manual visual comparison using a handheld colorimetric tube, and sometimes requires comparing the water sample with multiple standard colorimetric columns. This can be inconvenient and inefficient when switching between different standard colorimetric columns. Utility Model Content

[0006] Furthermore, the lighting assembly includes an incandescent lamp, the incandescent lamp is electrically connected to a controller, the controller is electrically connected to a touch switch, and the controller is controlled by the touch switch to control the brightness of the incandescent lamp.

[0007] Furthermore, the first rotating mechanism and the second rotating mechanism are symmetrically arranged.

[0008] Furthermore, the first rotating mechanism and the second rotating mechanism both include a rotating shaft, a rotating disk is rotatably connected to the rotating shaft, and a plurality of through holes are formed on the rotating disk.

[0009] Furthermore, there are 12 through holes.

[0010] Furthermore, the turntable is in a ring shape.

[0011] Furthermore, the base is an elliptical pure white frosted glass panel, and one side of the annular turntable protrudes from the outside of the shell.

[0012] Furthermore, the turntable is made of acrylic material.

[0013] Furthermore, the observation assembly includes a barrel that matches the turntable, and two symmetrical observation holes are opened on the barrel. The observation holes are matched with one of the colorimetric tubes and sample tubes on the turntable respectively.

[0014] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0015] The present application provides a shell on the top of the base, and a lighting assembly for adjusting the brightness is installed on the base.

[0020] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3As shown, a preferred embodiment of the present invention is a colorimetric device for detecting the colorimetric value of drinking water, comprising a base 1, a shell being provided on the top of the base 1, a light assembly 2 for adjusting the brightness being installed on the base, a first rotating mechanism 3 for placing a standard colorimetric tube, a second rotating mechanism 4 for placing a sample tube, and an observation assembly 5 for comparing the colorimetric tube and the sample tube being provided above the light assembly 2, the first rotating mechanism 3 and the second rotating mechanism 4 being installed in the shell, the observation assembly 5 being installed outside the shell and corresponding to the colorimetric tube and the sample tube, so that manual holding is not required and the colorimetric value of the standard color can be freely switched, which is convenient for the detection personnel to observe and detect multiple samples at the same time, thereby saving labor costs and improving detection efficiency.

[0022] As a preferred embodiment of the present invention, it may also have the following additional technical features: the lighting assembly 2 includes an incandescent lamp, the incandescent lamp is electrically connected to a controller, the controller is electrically connected to a touch switch 9, and the controller controls the brightness of the incandescent lamp through the touch switch 9, thereby realizing automatic adjustment of the brightness of the incandescent lamp, which is convenient for observation by detection personnel.

[0023] In this embodiment, the first rotating mechanism 3 and the second rotating mechanism 4 are symmetrically arranged, thereby facilitating colorimetric comparison between sample tubes and colorimetric tubes. The first rotating mechanism 3 and the second rotating mechanism 4 each include a rotating shaft 6, to which a turntable 7 is rotatably connected. The turntable 7 is provided with a plurality of through holes 8 for placing standard colorimetric tubes, with a total of 12 through holes. The turntable 7 is annular, with one side of the annular turntable 7 protruding from the exterior of the housing. This facilitates manual rotation of the turntable 7. A bearing is installed between the rotating shaft and the turntable 7, allowing the turntable 7 to rotate about the rotating shaft. This connection can be achieved using existing technology and will not be described in detail in this embodiment. However, this embodiment is not limited thereto and can also be controlled by a motor.

[0024] In this embodiment, the base 1 is an oval pure white frosted glass panel, and the turntable 7 is made of acrylic material, so as to facilitate observation by the inspection personnel.

[0025] In this embodiment, the observation assembly 5 includes a cylindrical body that matches the turntable 7. The cylindrical body is provided with two symmetrical observation holes 10 on the left and right. The observation holes 10 are respectively matched with one of the colorimetric tubes and the sample tube on the turntable 7. This facilitates the experimenter to perform colorimetric comparison on the water sample, which not only reduces the experimenter's workload but also improves detection efficiency.

[0026] The working principle of the present invention is as follows: the base 1 is an elliptical pure white frosted glass panel with an incandescent lamp inside. The brightness can be adjusted to facilitate visual color comparison by the inspector. Above it are symmetrically arranged circular acrylic turntables 7 with a diameter smaller than the base 1 and an edge protruding from the shell so that it can rotate. 12 standard colorimetric tubes are placed on the first circular turntable 7 through a first opening above the shell, and 12 sample colorimetric tubes are placed on the second circular turntable 7 through a second opening above the shell.

[0027] When in use, turn on the incandescent lamp, adjust the brightness, place the sample colorimetric tube on the second circular turntable, rotate the first circular turntable, observe the colorimetric through the observation hole 8, so that the sample colorimetric tube matches the corresponding standard color column colorimetric tube, and the chromaticity of the standard color column can be freely switched without manual holding, which is convenient for the inspection personnel to observe; multiple samples can be tested at the same time, saving labor costs and improving inspection efficiency.
