Description

Water quality detector suitable for underwater and capable of receiving vertical direction light information

Technical Field

The utility model belongs to the technical field of water quality detection, and particularly relates to a water quality detector which is suitable for underwater and can receive vertical light information.

Background

With the development of economy, nowadays, the environmental protection is more and more emphasized, water quality detection is essential for some industries, for example, turbidity is caused by suspended particles in water, the suspended particles can diffusely reflect incident light, the scattered light in the direction of 90 degrees is generally used as a test signal, the intensity of the scattered light is in a linear relation with the turbidity, therefore, the detection of the intensity of the scattered light can be converted into a value of the turbidity in water, and the method for measuring the scattered light is called scattering method. Therefore, the detector designed based on the principle has higher accuracy and reliability, is simple to maintain, is suitable for field and laboratory measurement, and is also suitable for all-weather continuous monitoring.

However, the above-mentioned optical receiving and transmitting in the vertical direction must use an optical lens, and two optical paths are provided in the 90 ° direction, respectively, so that there are disadvantages as follows:

1) the optical glass inclined lens has high processing cost, and the sealing installation of a lens window is complex and the reliability is poor when the optical glass inclined lens is detected underwater;

2) the installation structure of the light source emitting end and the receiving end matched with the optical glass lens is complex;

3) when detecting in water, detection bubbles inevitably occur, and once the bubbles are accumulated on the surface of the lens, the transmission and the reception of light beams are influenced, so that the detection accuracy is influenced.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide a brand-new water quality detector which is suitable for underwater and can receive vertical light information.

In order to solve the technical problems, the utility model adopts the following technical scheme:

a water quality detector suitable for underwater and capable of receiving vertical light information comprises a device body, a light beam emitting unit and a light beam receiving unit, particularly,

a body standing in water and having a top surface including a detection slope intersecting with a horizontal direction;

a light beam emitting unit including a light source, a first light transmitting module;

and the light beam receiving unit comprises a detector and a second light transmission module, wherein the light beam emitting end face of the first light transmission module, the light beam receiving end face of the second light transmission module and the detection inclined plane are arranged in a flush manner, and the light beam emitted from the light beam emitting end face and the light beam transmitted from the light beam receiving end face to the detector are vertically arranged.

Preferably, the first light transmission module extends along the length direction of the container body and is positioned at one side of the container body. Thus, the layout can be reasonable, and the optical path detection structure can be miniaturized.

According to a specific implementation and preferred aspect of the utility model, the first light transmissive module is a cured optical glue module. Meanwhile, the encapsulated optical structure is convenient to operate, the size of the integral optical device can be greatly reduced, and the miniaturization of the detector is facilitated.

Preferably, the first light transmission module comprises a first module and a second module which are arranged up and down, wherein the outer diameter of the first module is smaller than that of the second module, the upper end face of the first module is flush with the detection inclined plane, and the lower end part of the second module abuts against or is close to the light source. Therefore, on one hand, the module is convenient to form, and the formed structure is stable; on the other hand, the light beam is relatively concentrated along the light beam transmission path and is transmitted out of the first module, so that accurate detection results are more favorably obtained.

Furthermore, the second module is in covering fit with the emission end face of the light source. This avoids loss of the beam or interference between the emerging beams.

In this example, the first module is coaxial with the second module. The light beam transmission effect is optimal.

According to yet another specific implementation and preferred aspect of the utility model, the second light transmission module is a cured optical glue module, and the detector is positioned in the cured optical glue module. Therefore, the forming of the light-transmitting module is facilitated, and the reflected light beam can be received more accurately after the detector is positioned.

In addition, the angle formed by the detection inclined plane and the horizontal plane is 30-60 degrees. At this angle, even if a detection bubble is generated, the detection bubble is separated from the detection slope along the upstream of the detection slope.

Preferably, the detection slope forms an angle of 45 ° with the horizontal plane.

Simultaneously, the top surface still includes the terminal surface that extends from the upper end level of detecting the inclined plane. Therefore, the detection inclined plane is protected to a certain degree, and the situation that the end part where the detection end face is located is too sharp to cause inconvenience in implementation or accidental damage is avoided.

Due to the implementation of the technical scheme, compared with the prior art, the utility model has the following advantages:

on the premise of receiving the vertical direction optical information, on one hand, the lens is replaced by the light-transmitting module, so that the reliability of underwater sealing of the optical path is improved, the structure is simplified, and the cost is reduced; on the other hand, under the arrangement of the detection inclined plane, the influence of bubble accumulation on a measured value during measurement can be prevented, and the optical path detection structure can be further miniaturized.

Therefore, on one hand, the module is convenient to form, and the formed structure is stable; on the other hand, the light beam is relatively concentrated along the light beam transmission path and is transmitted out of the first module, so that accurate detection results are more favorably obtained.

In order to achieve better light beam transmission effect, the first module 211 is coaxial with the second module 212, and the outer diameter of the first module 211 is smaller than that of the second module 212.

The second module 212 is in covering fit with the emitting end face of the light source 20. This avoids loss of the beam or interference between the emerging beams.
