[0002] Turbidimeter is an instrument used to test the concentration of suspended matter in water. Existing turbidity meters are relatively small in size, mainly for the convenience of staff to carry. However, existing turbidity meters require many auxiliary tools, such as colorimetric tubes, wiping cloths and light shields. Since human energy is limited, when faced with a large number of auxiliary tools, it is difficult to maintain continuous attention and memory for each auxiliary tool, which may lead to forgetting to put the tool back in place after use, or failing to quickly recall the storage location of a tool when it is needed, thereby increasing the probability of losing the auxiliary tool. Therefore, when testing in the outside world, it is occasionally impossible to carry out due to the lack of auxiliary tools, resulting in the equipment being able to be used only in a fixed area and inconvenient to carry. In view of this, we propose a portable turbidity meter. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] A turbidity meter is an instrument used to test the concentration of suspended matter in water. Its core working principle is to use a light sensor and a light source to measure the turbidity of a liquid sample. When light passes through a liquid, if there are solid particles or suspended matter suspended in the liquid, these particles or suspended matter will scatter the light, making the light darker. The turbidity meter determines the turbidity of the liquid by measuring the intensity of light scattering. In order to improve the detection accuracy of the meter, many auxiliary tools are often required. However, the increase in the number of tools will affect the portability of the meter and make it inconvenient to use outside. In order to solve the above problems, we have proposed the following solutions.

[0022] Embodiment 1

[0023] Reference Figure 1-Figure 5 A portable turbidity meter is mainly composed of a meter body 1 and a dust shielding frame 2 rotatably mounted on one end of the meter body 1. A detection component 3 for improving the portability of the device is provided on the meter body 1. This embodiment achieves the effect of shielding the detection component 3 when not detecting by setting the dust shielding frame 2, thereby reducing the influence of external dust on the detection component 3. During detection, the turbidity of the liquid sample can be measured by the detection component 3 using an optical sensor and a light source.

[0024] Existing turbidity meters require many auxiliary tools, such as colorimetric tubes, wiping cloths, and light shields. Since human energy is limited, it is difficult to maintain continuous attention and memory for each auxiliary tool when faced with a large number of auxiliary tools. This may make it impossible to quickly recall the storage location of a tool when it is needed, thereby increasing the probability of losing the auxiliary tool and making the meter inconvenient to carry. In view of the above defects, in this embodiment, the turbidity detection of liquid samples is achieved through the setting of the detection component 3, and some auxiliary tools in the turbidity determination are replaced by the setting of the impurity removal rubber sleeve and the light shielding component 33, thereby improving the portability of the meter. The detailed implementation method is as follows:

[0025] The detection assembly 3 includes a detection sleeve 31 arranged on the upper part of the measuring instrument body 1 for detecting the turbidity of the water body, and a light sensor and a light source are arranged inside the detection sleeve 31, and a de-impurity rubber sleeve 32 is arranged on the upper part of the detection sleeve 31 for removing impurities outside the detection colorimetric tube, and a dust removal groove 34 is arranged on the measuring instrument body 1 and around the detection sleeve 31, and a de-impurity hole 35 that passes through the bottom of the measuring instrument body 1 is opened on the dust removal groove 34, and a light shielding component 33 is arranged inside the detection sleeve 31 for eliminating the influence of natural light on turbidity detection. When testing, the colorimetric tube containing the liquid sample can be directly placed in the detection sleeve 31. During the placement process, the de-impurity rubber sleeve 32 will fit the outer wall of the colorimetric tube and slide relatively, thereby achieving the effect of placing the colorimetric tube. The effect of removing dust from the outer wall of the tube replaces the function of the wiping cloth. The removed impurities fall into the dust removal groove 34 under the action of their own gravity, and finally separate from the measuring instrument body 1 from the impurity removal hole 35, so as to prevent impurities from adhering to the outer wall of the colorimetric tube and affecting the irradiation of the light source. At the same time, a relatively stable and controllable light environment can be created in the detection sleeve 31 through the shading component 33 to shield the interference of external natural light, replacing the function of the light shield. In this embodiment, the impurity removal rubber sleeve 32 and the shading component 33 are provided to replace some auxiliary tools in the turbidity measurement, thereby reducing the number of auxiliary tools and improving the portability of the measuring instrument. Moreover, these components are all provided on the measuring instrument body 1, so there is no need to worry about losing them.

[0026] The inner diameter of the impurity removing rubber sleeve 32 is smaller than the inner diameter of the detection sleeve 31, and the outer diameter of the impurity removing rubber sleeve 32 is larger than the outer diameter of the detection sleeve 31. The setting of the inner diameter and the outer diameter of the impurity removing rubber sleeve 32 improves the fit between the impurity removing rubber sleeve 32 and the colorimetric tube, thereby increasing the impurity removing effect of the impurity removing rubber sleeve 32. In addition, the cross-section of the impurity removing rubber sleeve 32 is triangular, and the outer diameter is larger than the detection sleeve 31. This design makes it easy for the dust cleaned on the impurity removing rubber sleeve 32 to slide along the impurity removing rubber sleeve 32 into the dust removal groove 34.

[0027] The shading assembly 33 includes an operating chamber 331 provided on the outer wall of the detection sleeve 31 and an accommodating chamber 332 provided on the inner wall of the detection sleeve 31, a shading plate 333 is rotatably installed in the accommodating chamber 332, a driving gear ring 334 is rotatably installed in the operating chamber 331, and a driving gear 337 coaxially fixed to the rotating end of the shading plate 333 is meshed on the inner side of the driving gear ring 334, a guide groove 335 is provided in the operating chamber 331, and a guide convex ring 336 fixed to the driving gear ring 334 is slidably installed in the guide groove 335. Since the working principle of the turbidity sensor involves sensitive detection of light, the intensity and changes of natural light will directly affect the sensitivity and accuracy of the sensor. Stray light in natural light may interfere with the turbidity sensor's measurement of scattered light from suspended particles in the liquid, thereby causing inaccurate measurement results. The present embodiment creates a relatively stable and controllable light environment during the measurement process through the setting of the shading component 33, thereby shielding the interference of external natural light. During operation, the driving gear ring 334 can be rotated to engage the driving gear 337. Since the driving gear 337 is coaxially fixed with the shading plate 333, the shading plate 333 will be synchronously driven to close to isolate the external natural light. In addition, the setting of the guide groove 335 and the guide convex ring 336 can guide the rotation of the driving gear ring 334 to avoid its deviation, thereby ensuring the stability of the operation of the shading component 33.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, the technical solution proposed in the first embodiment is used to solve the disadvantage that the existing turbidity meter can only be used in a fixed area and is inconvenient to carry. However, most of the impurities falling into the dust removal groove 34 will be gathered in the dust removal groove 34 under the action of friction resistance, and it is not easy to fall off from the impurity removal hole 35.

[0030] Reference Figure 1-Figure 5 The cross section of the ash removal groove 34 is V-shaped, and the impurity removal hole 35 is arranged at the lowest end of the ash removal groove 34. In this embodiment, the impurities are actively gathered to the impurity removal hole 35 under the action of their own gravity through the setting of the cross section of the ash removal groove 34, thereby improving the impurity removal efficiency.

[0031] A fixed suction cup 4 is provided at the bottom of the measuring instrument body 1. When the fixed suction cup 4 contacts the plane surface, the air inside the suction cup is sucked out to form a low-pressure area. Since the external air pressure is higher than the internal air pressure, a pressure difference is generated. This pressure difference causes a negative pressure to be generated on the contact surface between the fixed suction cup 4 and the plane surface, so that the measuring instrument body 1 can be firmly fixed on the plane during the detection process, ensuring the normal progress of the measurement work.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
