Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water body measurement, in particular to a water body transparency measuring device. Background Art
[0002] Water transparency can indicate the clarity of water and is one of the important indicators for water quality evaluation. On the one hand, the more serious the water pollution, the lower its transparency will be. The reduction in transparency will not only affect the living environment of aquatic organisms, but also damage the regional ecological environment. On the other hand, transparency, as an important parameter to describe the optical properties of water and the visibility of water, is an important indicator for measuring water quality and evaluating lake eutrophication. It is also one of the most intuitive indicators to reflect the effect of water environment engineering treatment. At the same time, in the study of static water bodies such as lakes and reservoirs, it is often used to calculate indicators such as water comprehensive nutrient index, true light layer thickness, and light compensation point, and the accuracy requirements for water transparency values are relatively high. Therefore, accurate determination of water transparency values can effectively serve many fields such as water ecological environment quality evaluation, comprehensive water environment treatment, and water ecological environment scientific research.
[0003] Water transparency measurement methods include the lead type method, the cross method, and the Secchi disk method. The most widely used transparency measurement method is the Secchi disk method (black and white disk method), which is to hang a black and white disk under a measuring tape and put it vertically into the water until the black and white disk cannot be distinguished by the eyes, and then read the scale on the measuring tape with the naked eye to complete the transparency measurement. This method has the advantages of convenience, speed, and ease of operation to a certain extent, but when measuring water bodies, there are wind and waves, disturbances, and flow rates, which can easily cause the transparency disk to capsize when it is below the water, and it is impossible to make the transparency disk sink into the water in a horizontal state, which ultimately leads to large errors in the transparency measurement results.

[0029] The housing 1 is formed with a closed cavity 101 and a plurality of first mounting points arranged in a circumferential array around the closed cavity 101, wherein the first mounting points are detachably provided with a first connecting rope 103;
[0030] A transparency disk 2, covering the closed cavity 101, the transparency disk 2 is provided with a second mounting point, the second mounting point is located in the middle of the plurality of first mounting points, and is penetrated by a second connecting rope 202;
[0031] The retracting member is disposed in the closed cavity 101 , and is connected to the second connecting rope 202 , so as to make the second connecting rope 202 expand outward under the action of an external force, and to make the second connecting rope 202 retract inward after the external force disappears.
[0032] In this embodiment, a closed cavity 101 is formed on the housing 1, and three first mounting points are arranged around the closed cavity 101. Three first connecting ropes 103 are arranged around the first mounting points. The transparent disk 2 is covered on the closed cavity 101, and a second mounting point is arranged at the center of the transparent disk 2. A second connecting rope 202 is arranged around the second mounting point. Before the transparent disk 2 is lowered into the water, the three first connecting ropes 103 are first pulled to the same length, and the three first connecting ropes 103 are connected to the second connecting rope 202, and then the second connecting rope 202 is used to connect the transparent disk 2 to the water. The transparent plate 2 is lowered into the water by the rope 202. The second connecting rope 202 cooperates with the first connecting rope 103 so that when the transparent plate 2 is lowered, a plurality of first connecting ropes 103 and second connecting ropes 202 are used to fix the object from different directions, thereby forming a multi-dimensional support structure to resist water flow fluctuations from different directions. Furthermore, a contraction member is provided in the closed cavity 101, and the contraction member is used to connect with the second connecting rope 202, so that when the second connecting rope 202 is pulled under the action of an external force, the second connecting rope 202 is expanded outward. , so that the transparency disk 2 can sink into the water smoothly, until the black and white disk of the transparency disk 2 can no longer be seen, the sinking can be stopped, and the depth of the transparency disk 2 in the water at this time is recorded. After use, the transparency disk 2 is taken out of the water, and the external force is removed so that the second connecting rope 202 can be contracted to avoid the second connecting rope 202 from being tangled during use, which is inconvenient to use; at the same time, a signal receiver 8, a signal transmitting device 10 and a pressure sensor 9 can be set on the housing 1. When in use, the local atmospheric pressure value is read as a reference value, and the reference value parameter is set in the system. The pressure sensor 9 device can measure the atmospheric pressure and water pressure, and the water depth is converted by measuring the water pressure at different depths and the local atmospheric pressure value. Then, the transparency disk 2 is placed in the water body, and when the transparency disk 2 is just invisible, the depth data and water pressure data on the liquid crystal display 7 are read; the signal receiver 8 is completely built in the closed cavity 101, and continuous depth measurement signal reception and display are realized through circuit connection; the signal receiver 8 is provided with a power switch to realize the measurement or shutdown function.
[0033] The retracting member is a clockwork spring, and the outer end of the clockwork spring is connected to the second connecting rope 202 .
[0034] In this embodiment, the contraction member is set as a clockwork spring, one end of the second connecting rope 202 is connected to the clockwork spring, and the other end thereof is connected to the outer end of the clockwork spring. Furthermore, a fixed shaft (not shown) is fixed at the center of the clockwork spring for fixed connection with the housing 1. When in use, the clockwork spring is deformed under the action of external force and the second connecting rope 202 has a tendency to move away from the clockwork spring, the second connecting rope 202 on the fixed shaft is stretched out, and the transparency disk 2 suspended in the air is sunk into the water by the second connecting rope 202. After the detection is completed, the transparency disk 2 in the water is retracted from the water, and the second connecting rope 202 away from one end of the transparency disk 2 is loosened, and the second connecting rope 202 is wound around the fixed shaft by the elasticity of the clockwork spring itself; the second connecting rope 202 is made of hydrophobic fiber material and will not absorb water and expand, thereby affecting the contraction efficiency.
[0035] The housing 1 is provided with a plurality of rotating buckles 104 in a circular array, the first mounting point is a first mounting hole 102 formed on the rotating buckle 104, the first connecting rope 103 is tied to the rotating buckle 104 through the first mounting hole 102, or the first connecting rope 103 is provided with a U-shaped buckle, and the U-shaped buckle is hung on the rotating buckle 104 through the first mounting hole 102.
[0036] In this embodiment, three rotating buckles 104 are provided on the outer shell 1, so that the transparency disk 2 can be set on the outer shell 1 through the rotating buckles 104 to form a whole, which is also convenient for the disassembly connection between the two, and also convenient for the first connecting rope 103 to form multi-point positioning of the transparency disk 2 through the first mounting hole 102; furthermore, in order to facilitate the fixing of the first connecting rope 103, a U-shaped buckle (not shown) can be provided on the first connecting rope 103, so that the first connecting rope 103 can be fixed on the rotating buckle 104, so as to fix the length of the first connecting rope 103.
[0037] The second mounting point is a second mounting hole 201 formed on the transparency plate 2 , and the second connecting rope 202 is passed through the second mounting hole 201 .
[0038] In this embodiment, the second connecting rope 202 is passed through the second mounting hole 201 and cooperates with the first connecting rope 103 to form a multi-dimensional supporting structure when the transparent plate 2 is suspended.
[0039] The transparency disk 2 is hinged with a plurality of diversion weight blocks 3, and the diversion weight blocks 3 have a use state that can be rotated to be perpendicular to the transparency disk 2, and a storage state that can be rotated to be parallel to the transparency disk 2. The diversion weight blocks 3 switch between the use state and the storage state to open or close the second mounting hole 201, and release or restrict the movement of the second connecting rope 202.
[0040] In this embodiment, a guide weight block 3 is hinged on the transparency disk 2. The guide weight block 3 is an elliptical structure and is located above the second mounting hole 201. When the guide weight block 3 rotates, it can be rotated so that its flat surface and the transparency disk 2 are perpendicular to each other, thereby achieving a guide effect.

Further, the shell 1 is provided with a plurality of first water-permeable holes 4, and the transparency disk 2 is provided with a plurality of second water-permeable holes 5. The plurality of first water-permeable holes 4 and the plurality of second water-permeable holes 5 are arranged one by one in the vertical direction. The shell 1 and the transparency disk 2 are provided with a plurality of first water-permeable holes 4 and second water-permeable holes 5 that correspond one by one in the vertical direction, so as to reduce the contact area between the shell 1 and the transparency disk 2 and the water. At the same time, the first water-permeable holes 4 and the second water-permeable holes 5 cooperate with each other to guide the transparency disk 2 when it sinks, and also facilitate the pressure sensor 9 to fully contact with the water.
[0043] The housing 1 is provided with a fixed armrest 6 .
