The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
As shown in fig. 1-5, the detector for detecting the transparency of water bodies at different depths comprises a detection disc 1 and a take-up disc 4, wherein a lifting disc 8 capable of driving the detection disc 1 to sink or float underwater is detachably connected to the lower end surface of the detection disc 1. The take-up reel 4 is wound with a sampling rope 11 with scales, and one end of the sampling rope 11 is fixed at the central position of the upper end face of the detection disc 1.
A pair of support rods 5 is arranged on the lower end face of the take-up reel 4, and an angle scale 13 is arranged between the pair of support rods 5. A through hole 14 for the sampling rope 11 to pass through penetrates through the angle scale 13, and a scale mark 16 convenient for identifying the offset angle of the sampling rope 11 in the through hole 14 is arranged on the angle scale 13.
When the detector is used, the lifting disc 8 is installed on the lower end face of the detection disc 1 according to the requirement of a water body, so that the detection disc 1 can be ensured to be smoothly settled or floated in the water body. Drive under the effect through lifting disk 8 and detect dish 1 and sink to the water in, rotate take-up reel 4 simultaneously and twine sampling rope 11 down to detect dish 1 downstream gradually this moment. Until the detection disc 1 sinks to the depth just not clear, the scales of the sampling rope 11 on the water surface are observed, the total length of the sampling rope 11 sinking into the water body is determined, and the detection of the transparency of the water body is realized.
When the sampling rope 11 is displaced under the action of wind waves and flow velocity, the sampling rope 11 slides along the inner wall of the through hole 14. Therefore, after the total length of the sampling rope 11 sinking into the water body is determined by observing the scale of the sampling rope 11 at the position of the water surface, the deflection angle of the sampling rope 11 in the through hole 14 is observed, and the accurate deflection angle value is read by the angle scale 13. And finally, calculating the vertical distance from the water surface to the upper end surface of the detection disc 1 by utilizing the cosine law, namely calculating the actual transparent depth of the water body, and realizing the accurate detection of the transparency.
Furthermore, the sampling rope 11 comprises a rope body, a transparent plastic sleeve 12 is coated outside the rope body, and scales are arranged on the surface of the plastic sleeve 12.
Further, two bracing pieces 5 are close to each other towards the one end of take-up reel 4, and the one end that take-up reel 4 was kept away from each other and is connected with angle scale 13 to two bracing pieces 5, and this angle scale 13 is circular-arc.
Further, the angle scale 13 includes a transparent housing 15 and a light bar 17 located in the housing 15, and the scale marks 16 are located on the upper end surface of the housing 15. When using above-mentioned detector under the darker condition of light, open lamp strip 17, the light that sends through lamp strip 17 this moment shines 16 positions of scale mark, makes things convenient for the measurement personnel to read out the reading on the angle scale 13 for measurement process is light convenient more.
Furthermore, the upper end surface of the shell 15 is slidably connected with a support 18, a ring body 19 for the sampling rope 11 to penetrate through is arranged on the support 18, and a cleaning cloth 20 abutting against the outer wall of the plastic sleeve 12 is embedded in the ring body 19.

Further, a hollow cavity 25 is arranged inside the lifting disc 8, an inlet and outlet water port 26 communicated with the hollow cavity 25 is arranged at the bottom of the lifting disc 8, an inlet and outlet air port 27 communicated with the hollow cavity 25 is arranged at the top of the lifting disc 8, the inlet and outlet air port 27 is connected with a high-pressure air compressor 29 through a hose 28, and a control valve 30 is further arranged on the hose 28. The bottom of the lifting disc 8 is connected with a heavy stone 31, and the total weight of the heavy stone 31 is smaller than the buoyancy generated in water after the air enters the hollow cavity 25. Through injecing the gross weight of sinking stone 31, and then when guaranteeing that cavity appearance chamber 25 in the lifter plate 8 is filled with gas, lifter plate 8 all arranges the surface of water with detection dish 1 on.
When the hollow cavity 25 of the lifting plate 8 is filled with air, the air in the hollow cavity 25 is blocked by the water from the water inlet 26 and the water outlet 26, so that the air is blocked in the hollow cavity 25, the lifting plate 8 floats on the water surface under the action of the buoyancy force applied to the lifting plate 8, and the detection plate 1 is arranged on the water surface.
When the lifting disc 8 needs to be settled, and then the detection disc 1 is driven to sink, the control valve 30 on the hose 28 is opened, so that the air in the hollow cavity 25 is discharged from the air inlet and outlet 27 at the top of the lifting disc 8, and at this time, the lifting disc 8 pulls the sinking stone 31 to enable the water body to enter the hollow cavity 25 from the water inlet and outlet 26 at the bottom of the lifting disc 8. Along with the water increase in cavity appearance chamber 25, and then increase the weight of lifter plate 8, lead to lifter plate 8 to subside downwards and drive test panel 1 and subside downwards, rotate take-up reel 4 simultaneously and twine sampling rope 11 down. When the lifting disc 8 is completely submerged in the body of water, the control valve 30 is closed.
When the lifting disc 8 needs to be lifted, the high-pressure air compressor 29 is firstly opened, then the control valve 30 is opened, high-pressure air enters the hollow cavity 25 from the air inlet and outlet 27 through the high-pressure air compressor 29, and water in the hollow cavity 25 is discharged from the liquid inlet and outlet under the pushing of the high-pressure air. When a certain amount of air is filled into the hollow cavity 25, the buoyancy force applied to the lifting disc 8 is larger than the weight of the sinking stone 31, and then the lifting disc rises upwards. When fully floating on the water surface, the control valve 30 and the high pressure air compressor 29 are closed.
Further, the air inlet and outlet 27 and the water inlet and outlet 26 are respectively located at both ends of the lifting plate 8. After the high-pressure gas is introduced into the hollow cavity 25, the high-pressure gas can disturb the water body in the hollow cavity 25. If the air inlet and outlet 27 and the water inlet and outlet 26 are disposed at the same end of the lifting plate 8, the air may be directly discharged from the water inlet and outlet 26, and it is not guaranteed that the water in the hollow cavity 25 is completely discharged. The present application makes the water body move towards the water inlet/outlet 26 under the push of the high pressure gas by prolonging the stroke of the gas as much as possible, so as to discharge the water body as much as possible.
Furthermore, both ends of the lifting plate 8 are respectively connected with a heavy stone 31, and the weight of the heavy stone 31 at one end of the air inlet 27 is larger than that of the heavy stone 31 at one end of the water inlet 26. When the lifting disc 8 is settled, the water body enters the hollow cavity 25 at the water inlet and outlet 26, so that the water body is gathered at one end of the water inlet and outlet 26, and the lifting disc 8 is inclined and settled. And the balance of both ends of the lifting plate 8 during the settling process is adjusted by increasing the weight of the settling stone 31 using one end of the air inlet 27 and the air outlet 27. And when the lifting disk 8 rises, the water body is driven to one end of the water inlet and outlet 26 by high-pressure gas, so that the water body still gathers at one end of the water inlet and outlet 26, the lifting disk 8 inclines and rises in the rising process, and at the moment, the weight of the heavy stone 31 is increased by adopting one end of the water inlet and outlet 27, so that the balance of the two ends of the lifting disk 8 in the rising process is adjusted.
Further, the lower end face of the detection disc 1 is vertically provided with an installation rod 2, the upper end face of the lifting disc 8 is provided with an installation hole 9 for the installation rod 2 to be inserted, and one side of the lifting disc 8 is provided with a locking part 21 for detachably and fixedly connecting the lifting disc 8 and the installation rod 2.
Further, the locking portion 21 includes a pair of locking levers 22 disposed parallel to each other, one end of each of the two locking levers 22 is connected to a same connecting rod 23, and an end of each of the locking levers 22 away from the connecting rod 23 is provided with an elastic convex ball 24. The lateral wall of lifting disk 8 runs through and is provided with locking hole 10, and locking hole 10 intercommunication mounting hole 9 just supplies locking lever 22 to peg graft and slide to be provided with the round locking groove 3 that supplies the embedding of locking lever 22 on the installation pole 2.
When the lifting disc 8 is installed, the installation rod 2 of the lower end face of the detection disc 1 is inserted into the installation hole 9 on the lifting disc 8, then the elastic convex ball 24 is embedded into the locking hole 10 of the side wall of one side of the lifting disc 8, and then the connecting rod 23 is driven to drive the locking rod 22 and the elastic convex ball 24 to slide along the inner wall of the locking hole 10. Simultaneously locking lever 22 wears to establish gradually behind the locking groove 3 of installing the 2 outer walls of pole, wears out along the locking hole 10 of opposite side again to elasticity protruding ball 24 breaks away from locking hole 10 and contradicts the outer wall of lifter plate 8 this moment, thereby realizes the spacing of the vertical direction of installation pole 2, realizes locking portion 21 and lifter plate 8's locking promptly and fixes.
When the locking part 21 is detached, the connecting rod 23 is pulled to drive the locking rod 22 and the elastic convex ball 24 to move reversely, at this time, the elastic convex ball 24 is separated from the outer wall of the lifting disk 8 and embedded into the locking hole 10, and then the locking rod 22 slides outwards along the inner wall of the locking hole 10. After the locking rod 22 is completely separated from the locking groove 3 and the locking hole 10, the vertical limit of the mounting rod 2 is released, namely the locking part 21 and the lifting disc 8 are released. And finally, pulling the detection disc 1 to drive the installation rod 2 to move upwards until the installation rod 2 is separated from the installation hole 9, so that the lifting disc 8 can be detached.
