Description

Technical Field

[0001] This utility model relates to the field of river environmental water quality testing technology, specifically a sampling device for river environmental water quality testing. Background Technology

[0002] River environmental water quality testing is a core means of assessing river ecological health and ensuring water resource security. Through specialized equipment and technology, it systematically monitors the physical, chemical, and biological indicators of water bodies. The testing indicators cover physical parameters such as water temperature and transparency; chemical indicators such as pH, dissolved oxygen, chemical oxygen demand (COD), ammonia nitrogen, and total phosphorus; and biological indicators such as plankton and benthic organisms. This comprehensively reflects the degree of water pollution and its self-purification capacity. The process typically includes on-site sampling (collecting representative water samples according to regulations), laboratory analysis (accurately measuring indicator values), data interpretation, and report generation. It provides a scientific basis for river pollution control, ecological restoration plan development, and water resource management, helping to maintain river ecological functions and drinking water safety.

[0003] Most commercially available sampling devices for river environmental water quality testing rely on manual sampling. When a large amount of impurities or flocculent matter floats on the surface of the river, the sampling device lacks a filtration structure, resulting in a sample at the sampling point being rich in impurities. This will greatly affect the test data in subsequent tests. Utility Model Content

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a sampling device for testing water quality in river environments, including a suspended platform 1 and a sampling box 2. The sampling box 2 is disposed inside the suspended platform 1, and a filter mechanism 3 is disposed inside the sampling box 2.

[0028] The filtration mechanism 3 includes a support plate 31, a filter screen 32, and a telescopic component 33. The support plate 31 is disposed inside the sampling box 2, the outer surface of the filter screen 32 is fixedly connected to the inner wall of the support plate 31, and the telescopic component 33 is disposed on the upper surface of the support plate 31.

[0029] Specifically, the filtration mechanism 3 can effectively isolate large impurities or flocculent matter in the water, ensuring that the water source inside the sampling chamber 2 is not interfered with by external impurities during testing.

[0030] Furthermore, when the lower surface of the sampling chamber 2 is immersed in the river channel, water will pass through the filter screen 32 and enter the sampling chamber 2, while larger impurities will be isolated by the filter screen 32.

[0031] Example 2

[0032] In the second embodiment of this utility model, two telescopic components 33 are provided. The two telescopic components 33 include a first sliding groove 331 and a spring 332. The first sliding groove 331 is opened on the inner wall of the sampling box 2. The inner wall of the first sliding groove 331 is slidably connected to the outer surface of the support plate 31. Two springs 332 are provided. The lower end face of the two springs 332 is fixedly connected to the support plate 31.

[0033] A support plate 4 is provided on the surface of the filter screen 32, and the outer surface of the support plate 4 is fixedly connected to the surface of the filter screen 32.

[0034] A connecting rod 5 is provided on the upper surface of the support plate 4. The lower end face of the connecting rod 5 is fixedly connected to the upper surface of the support plate 4. A sealing component 6 is provided on the upper end face of the connecting rod 5.

[0035] The sealing assembly 6 includes an isolation plate 61, a placement groove 62, a sealing ring 63, and a fixing block 64. The outer surface of the isolation plate 61 is fixedly connected to the inner wall of the sampling box 2. The placement groove 62 is opened on the surface of the isolation plate 61. The outer ring of the sealing ring 63 fits against the inner wall of the placement groove 62. The inner ring of the sealing ring 63 is fixedly connected to the outer surface of the fixing block 64. The lower surface of the fixing block 64 is fixedly connected to the upper end face of the connecting rod 5.

[0036] Specifically, through this design, the opening and closing state of the sealing component 6 can be achieved indirectly by using the buoyancy of the water without manual operation, thus enabling the free entry and exit of water.

[0037] Furthermore, when the sampling box 2 is immersed in water, the buoyancy of the water pushes the support plate 31 to move upward along the inner wall of the first sliding groove 331, causing the support plate 31 to compress the spring 332. The spring 332 generates elastic force. At the same time, the support plate 31 drives the support plate 4 to move upward through the filter screen 32, causing the support plate 4 to push the fixed shell upward through the connecting rod 5. The fixed block 64 then drives the sealing ring 63 to detach from the placement groove 62. The water in the river will enter the upper side of the isolation plate 61. When the sampling box 2 leaves the river, the buoyancy of the water disappears, causing the spring 332 to release its elastic force and push the support plate 31 to move back. Indirectly, the sealing ring 63 enters the placement groove 62 and fits tightly against the placement groove 62, thus separating the lower side of the isolation plate 61 from the upper side of the isolation plate 61.

[0038] Example 3

[0039] In the third embodiment of this utility model, a driving assembly 7 is provided on the upper surface of the sampling box 2. The driving assembly 7 includes a fixing member 71, a push-pull rod 72, a connecting plate 73, and an electric cylinder 74. Two fixing members 71 are provided, and the lower surfaces of the two fixing members 71 are fixedly connected to the upper surface of the sampling box 2. Two push-pull rods 72 are provided, and the lower ends of the two push-pull rods 72 are rotatably connected to the inner wall of the fixing member 71 through a rotating shaft. The lower surface of the connecting plate 73 is fixedly connected to the upper surface of the push-pull plate. The output end of the electric cylinder 74 is fixedly connected to the upper surface of the connecting plate 73, the lower surface of the electric cylinder 74 is fixedly connected to the upper surface of the suspended platform 1, and the outer surface of the output end of the electric cylinder 74 is slidably connected to the inner wall of the suspended platform 1.

[0040] The inner wall of the suspended platform 1 is provided with a second slide groove 8. There are two second slide grooves 8, and the inner walls of the two second slide grooves 8 are slidably connected to the outer surface of the sampling box 2.

[0041] Specifically, this design enables the sampling box 2 to move in and out of the river channel.

[0042] Furthermore, the connecting plate 73 is pushed down by the electric cylinder 74, and the connecting plate 73 drives the fixing member 71 through the push rod, so that the fixing member 71 pushes the sampling box 2 to move down along the inner wall of the second slide 8 until the sampling box 2 is immersed in the river.

[0043] Working principle:

[0044] The electric cylinder 74 pushes the connecting plate 73 downward, and the connecting plate 73 drives the fixing member 71 through the push rod, so that the fixing member 71 pushes the sampling box 2 to move downward along the inner wall of the second slide 8 until the sampling box 2 is immersed in the river. The buoyancy of the water pushes the support plate 31 to move upward along the inner wall of the first slide 331, so that the support plate 31 compresses the spring 332, and the spring 332 generates elastic force. At the same time, the support plate 31 drives the support plate 4 to move upward through the filter screen 32, so that the support plate 4 pushes the fixing shell upward through the connecting rod 5. The fixing block 64 drives the sealing ring 63 to disengage from the placement groove 62, and the water in the river will enter the upper side of the isolation plate 61.

[0045] After a period of time, the electric cylinder 74 pulls the connecting plate 73 to move back quickly, indirectly causing the sampling box 2 to leave the river channel. The loss of buoyancy of the water causes the spring 332 to release its elasticity, pushing the support plate 31 to move back. Indirectly, the sealing ring 63 enters the placement groove 62 and fits tightly with the placement groove 62, separating the lower side of the isolation plate 61 from the upper side of the isolation plate 61.

[0046] At this point, the staff can retrieve the device, disassemble it, and then take out the entire sampling device along the second chute 8. By rotating the sampling box 2 with the fixing part 71 as the rotation center, the sample inside the sampling box 2 can be poured out for testing.

[0047] In summary, the combination of the filter mechanism 3, support plate 4, connecting rod 5, sealing component 6, drive component 7, and second chute 8 solves the problem that when a large amount of impurities or flocculent matter floats on the surface of the river, the sampling device lacks a filtration structure, resulting in the sample at the sampling point being rich in impurities, which will greatly affect the test data in subsequent tests.
