Description

Technical Field

[0001] The invention relates to the technical field of water environment protection, in particular to a portable device for measuring transparency of surface water shore water body. Background Art

[0002] According to the requirements of relevant standards such as SL87-1994 "Determination of transparency (transparency meter method, disk method)", on-site determination of transparency of natural water, slightly polluted water and surface water is widely used. Among them, the disk method determines the transparency of surface water. The disk is immersed in the water and the length of the part of the suspension rope that enters the water when the disk cannot be observed is recorded; the transparency meter is to fully mix the water sample and transfer it to the transparency meter. By gradually lowering the sample height, the height of the water column where the printing and test marks can be clearly seen is read. Because the disk method needs to invade the water body, it has high requirements for the depth of the water body and the detection position. It is necessary to take a boat to measure in waters with slow water flow or on the shore with ideal water depth and slow water flow. The measurement is seriously restricted by on-site conditions; the transparency meter is 600mm long. Due to the length and the material of the barrel, the range is small and it is not suitable for the measurement of clean water bodies such as water source reservoirs. At the same time, it is not easy to carry. When measuring, a flat ground or work platform is required for accurate measurement. It is rarely used in on-site determination of surface water.

[0030] Scale lines 31 are provided on the outer wall of the measuring tube 3, and a sealing plug 32 is provided inside the measuring tube 3. A connecting rod can extend into the measuring tube 3 and is fixedly connected to the sealing plug 32. The connecting rod can push the sealing plug 32 to reciprocate inside the measuring tube 3.

Through the observation eyepiece 11, the second dial 33, the first dial 421 or the mirror 422 can be observed in the reflector 12.

[0031] In one embodiment, the light path tube 2 is made of opaque metal or polymer material.

[0032] In one of the embodiments, rubber plugs 43 are provided on the outer walls at both ends of the V-shaped connector 4, and the V-shaped connector 4 can be extended into the optical path tube 2. The rubber plug 43 can seal the connection between the V-shaped connector 4 and the optical path tube 2. After the V-shaped connector 4 is connected to the two sides of the optical path tube 2, the distance between the two inflection points is fixed, and the optical path tube 2 of different lengths can be designed according to needs.

[0033] In one embodiment, a through hole is opened at the outer corner of the V-shaped connector 4 , and a transparent glass is sealed at the through hole to form a transparent observation window 41 . The size of the transparent observation window 41 is not less than the size of the turntable 42 .

[0034] In one embodiment, an observation port 423 is formed on the turntable 42 .

[0035] Furthermore, the turntable 42 is circular, the observation port 423 is a notch, 1 / 4 circle, the first scale plate 421 is 1 / 2 circle, the mirror 422 is 1 / 4 circle, and the turntable 42 can rotate in a clockwise or counterclockwise direction on the transparent observation window 41. By rotating, it is possible to check whether the inflection point glass is clean at the V-shaped inflection point, increase the range by the reflection of the mirror 422, or perform a preliminary measurement of the light path blocked by the first scale plate 421.

[0036] In the embodiments provided by the present invention, more preferably, the portable surface water shore water transparency measuring device also includes a tail plug 44, the optical path tube 2 located at the tail end is the optical path tube tail tube, the tail plug 44 can seal the end of the optical path tube tail tube away from the V-shaped connector 4, and a third dial 45 is provided on the side of the tail plug 44 close to the inside of the optical path tube tail tube.

[0037] In one embodiment, the connecting rod is a screw 47, and the end of the measuring tube 3 is rotatably connected to a screw hole 46, and the screw 47 is threadedly connected to the screw hole 46. Rotating the screw hole 46 can make the screw 47 move forward and backward.

[0039] During the measurement of water transparency, according to the historical transparency measurement value or the preliminary estimation in the absence of historical data, several optical path tubes 2 are connected through the V-shaped connector 4 behind the optical path tube head tube 1 to achieve the required transparency value. The turntable 42 at the turning point of the V-shaped connector 4 connected to each section of the optical path tube 2 is adjusted to a mirror surface 422. When working, the whole device is immersed in water. After exhausting the air inside, the observation eyepiece 11 is sealed and connected to the optical path tube head tube 1, and the optical path tail plug 44 is sealed and connected to the optical path tube tail tube. The water body to be measured is sealed in the equipment for a short period of time by observing the rotating optical path tube 2 connected to the turntable 42 at the turning point of the V-shaped connector 4 from far to near through the eyepiece 11, and the black and white pattern of the first dial 421 can be clearly seen from the reflector 12 to the dial, thereby completing the preliminary measurement of the transparency of the water body; then replace the optical path tube 2 with the measuring tube 3 after the last adjusted V-shaped connector 4, adjust the turntable 42 at the turning point of the V-shaped connector 4 back to the mirror surface 422, and repeat the above immersion in water and sealing operations. By rotating the screw 46 to screw in the screw rod 47, the second scale plate 33 and the sealing plug 32 are pushed to move into the optical path tube 2. At the same time, the water in the tube is discharged from the tube through the pressure difference between the inside and outside of the sealing plug 32, so that the second scale plate 33 and the sealing plug 32 are continuously moved deeper in the measuring tube 3 until the second scale plate 33 can be clearly seen through the observation eyepiece 11, and the water transparency value is calculated according to the scale line 31 on the measuring tube 3 indicated by the pointer 49.

[0040] The present invention adopts a modular design, adjusts the transparency measurement range by splicing as needed, and transfers the water body to the equipment by immersion, thus getting rid of the limitations of transparency monitoring on on-site conditions such as ships and shore water depth, and avoiding the influence of water flow velocity on transparency measurement, making it possible to measure water transparency on the shore, thereby improving the scientificity and effectiveness of water transparency measurement.
