Description

Technical Field

[0001] The invention relates to the technical field of water quality detection, and in particular to a water quality sampling and detection device for water conservancy and hydropower construction. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production.

[0003] Referring to the Chinese invention patent, the publication number is: CN114544896A, and the name is: A water quality sampling and detection device for water conservancy and hydropower construction. The invention is supported by mobile wheels and is easy to move; a one-way valve is installed at the mouth of the sample collection tank to avoid leakage of sample liquid during movement or transportation; multiple sample liquids can be stored at the same time, which is convenient for sampling and storage in different places; after sampling, the sampling pipeline and water pump can be cleaned to avoid cross-mixing of samples and ensure the accuracy of the test data; the built-in water quality detection module can detect water quality in real time, which is convenient for timely understanding of water quality information.

[0004] However, there are still some problems in actual use:

[0005] 1. In the design of the above technical solution, although a water storage tank is introduced to facilitate carrying clean water for cleaning water pipes and water storage bottles, effectively avoiding the risk of cross contamination, this also brings disadvantages: the increase in the volume of the water storage tank directly leads to the expansion of the volume of the entire box, which in turn increases the inconvenience of carrying, especially in the complex and changeable terrain along the river. Even if equipped with mobile wheels, the huge volume and weight of the box still greatly limit its mobility, which undoubtedly increases the difficulty of water sample collection and the complexity of operation;

[0006] 2. In the actual sampling process, when the water pipe is directly put into the water, there is a lack of an effective depth control mechanism, which causes the water suction end of the water pipe to easily sink to the bottom of the water uncontrollably, and may then suck in impurities such as mud and sand, affecting the purity of the water sample. To avoid this, it is usually necessary to manually hold the water pipe continuously to accurately control its depth in the water. This operation is not only time-consuming and laborious, but also easily leads to increased fatigue of the operator, especially in the scenario of long-term continuous sampling. This problem is particularly prominent;

[0007] 3. When storing water samples, it is troublesome to judge whether there is water in the water storage bottle by controlling each indicator, and it is easy to be confused. In the process of docking the water storage bottle with the box, due to improper operation or poor sealing, water samples are likely to overflow, which can easily cause the surface of the box to be wet, increasing the risk of corrosion and contamination of the box. Summary of the invention

[0055] Embodiment 3:

[0056] Based on Example 2, Fig.14 A water quality sampling and detection device for water conservancy and hydropower construction, a display mechanism 4 is connected to the rotating disk 52, the display mechanism 4 includes a shading plate 41 and a diffuser plate 42, the rotating disk 52 is located above the water storage bottle 57 and is installed with the shading plate 41 and the diffuser plate 42, and the box body 1 is located below each shading plate 41 and is installed with a laser lamp 43.

[0057] In the present invention, the side of the shading plate 41 facing the water storage bottle 57 is black, and the light diffusion plate 42 is white and translucent, so as to facilitate the rapid determination of the position of the empty water storage bottle 57 .

[0058] Working principle: When testing the water quality at the construction site, open the box 1, take out the water bottle 57, point the threaded cover end of the water bottle 57 toward the rotating disk 52, and insert it into the rotating disk 52. The fourth spring 931 pushes the limit block 932 to extend into the limit groove 933, thereby limiting the free sliding of the water bottle 57 and preventing the water bottle 57 from falling off when the rotating disk 52 rotates. The battery 7 is an electrical component that provides power support to control the electric push rod 91 to work and push the second docking pipe block 56. The fifth spring 96 The fixing block 92 is in contact with the bottom end of the water storage bottle 57 under the action of the second butt joint pipe block 56, and the second butt joint pipe block 56 continues to move toward the rotating disk 52, so that the water inlet hole 95 end of the second butt joint pipe block 56 is in contact with the rubber block 94, and the fifth spring 96 is compressed to push the fixing block 92 to be in close contact with the water storage bottle 57, and the water inlet hole 95 end of the second butt joint pipe block 56 pushes the rubber block 94 to slide, and the sixth spring 97 is compressed, and the water inlet hole 95 is exposed from the inside of the fixing block 92 and extends into the inside of the water storage bottle 57. At this time, sampling can be carried out. The water pipe 51 with the water inlet cylinder 61 is thrown into the water, and the water pump 53 is started. The water is pumped into one of the channels of the water pipe 51 under the negative pressure of the water pump 53, and then enters the water storage bottle 57 through the first butt joint pipe block 54 and the second butt joint pipe block 56. When a certain amount of water accumulates in the water storage bottle 57, the water passes through the second butt joint pipe block 56, the water pump 53 and the first butt joint pipe block 54, and is discharged from the other channel of the water inlet pipe 51, so that when the water is sampled, the water flow can continuously flush the water storage bottle 57, so that the water storage bottle 57 is filled with water. Other liquids or impurities remaining in the water bottle 57 are discharged, so there is no need to manually clean the water storage bottle 57, and there is no need to carry pure water. After the sampling is completed, the electric push rod 91 is driven in the reverse direction to pull out the second docking pipe block 56, and the rotating disk 52 is driven to rotate. The water storage bottle 57 carrying the covered water sample faces outward, and it can be pulled out. The water sample can be tested by the water quality detection probe 3. Before starting the sampling, multiple water storage bottles 57 can be inserted on the rotating disk 52, so as to facilitate unified testing after the sampling is completed;

[0059] During the sampling process, the laser lamp 43 works and is tilted. The emitted light will penetrate into the water storage bottle 57 and be emitted from the other end of the water storage bottle 57. When there is no water sample inside the water storage bottle 57, the light of the laser lamp 43 will not be deflected. When passing through the water storage bottle 57, it will be emitted onto the shading plate 41. The shading plate 41 is black, so as to better absorb light. When there is water sample inside the water storage bottle 57, according to Snell's law (also called the law of refraction):

[0060] n1 sin(θ1)=n2 sin(θ2)

[0061] Among them, n1 and n2 are the refractive indices of two media respectively (n1 is the refractive index of water, and n2 is the refractive index of air), θ1 is the incident angle, and θ2 is the refractive angle. Since the refractive index of water is greater than that of air (n1>n2), when the incident angle θ1 is fixed, the refractive angle θ2 will be greater than the incident angle θ1. Therefore, when the light passes through the air from the water (actually, it is obliquely incident from the water to the water surface and refracted into the air), the incident angle will be smaller than the refractive angle. This is because the refractive index of water is greater than that of air, which causes the refraction phenomenon. The light will be deflected, and the landing point of the light will be offset, so that it will be incident on the diffuser plate 42, thereby illuminating the diffuser plate 42, so that it is convenient to quickly observe which water storage bottle 57 has water sample, and it is convenient to drive the rotating disk 52 to rotate through the controller 2, so as to facilitate the empty water storage bottle 57 to align with the second docking pipe block 56;

[0062] When the water inlet cylinder 61 is thrown into the water for sampling, the end of the water inlet cylinder 61 is floated by the floating block 62. The water inlet cylinder 61 is made of plastic material. The bottom of the water inlet cylinder 61 is slightly inclined to enter the water, and the water pump 53 is controlled to work, and water sampling can be carried out. When the pumping power of the water pump 53 is increased, the water flow rate will become faster, and the protective net 64 can intercept the aquatic plants. By unscrewing the end block 65, the protective net 64 can be cleaned. The pumping power of the water pump 53 is increased, and the amount of water discharged at the same time will increase. The aperture of the drainage hole 63 is constant, so that the discharged water flow rate becomes faster, and the water pressure inside the water inlet cylinder 61 will increase, pushing the piston 68 to move downward, the first spring 67 will be compressed, and the through hole 66 is used to balance the pressure. The second spring 692 pushes the resistance block 693 to extend into different slots 691. The closer the piston 68 is to the through hole 66, the shorter the first spring 67 will be compressed, and the greater the force required , thereby controlling the power of the water pump 53 to facilitate the adjustment of the position of the piston 68, the abutment block 693 and the card slot 691 are the thresholds for the movement of the piston 68, thereby limiting the movement of the piston 68 under a certain pressure, and the pressure breaks through the critical point generated by the abutment block 693 and the card slot 691, and the piston 68 can slide again. The interior of the piston 68 is made of metal material, so the center of gravity of the water inlet cylinder 61 is adjusted by the piston 68. When the piston 68 is down, the center of gravity of the water inlet cylinder 61 is down, so that the bottom end of the inclined water inlet cylinder 61 moves underwater, thereby facilitating the adjustment of the state of the water inlet cylinder 61. The water inlet cylinder 61 is vertical, which is convenient for sampling the deep water layer.
