Description

Technical Field

[0001] The utility model relates to the field of sewage sampling, in particular to sewage sampling equipment for water resource environment detection. Background Art

[0002] Human beings cannot live without water in their daily life and production activities. The quality of water is closely related to human health. In order to ensure the sustainable development of water resources, the detection and investigation of water bodies have become indispensable tasks. When collecting water sources from rivers and lakes for testing, a water sample collector is generally used for collection. It is mainly composed of a water collection bottle and a rope. When in use, the water collection bottle is thrown into the water to collect water sources. After the collection is completed, the rope is pulled to retract the water collection bottle to collect the water source. However, when the current water sample collector collects water from deeper water flow layers, because the water point is the water source of the upper water flow, part of the upper water source will not flow out when the water collection bottle descends, which can easily cause part of the upper water source to be collected in the water collection bottle, affecting the test results.

[0022] Example

[0023] See also Figure 1-5 A sewage sampling device for water resource environment detection comprises a water sampling bottle 1 and a first rope 2 connected to the upper end of the water sampling bottle 1, the bottom surface and the upper surface of the water sampling bottle 1 are respectively provided with corresponding water inlet holes 3 and water through holes 4, an adjusting rod 5 is penetrated in the water inlet hole 3 and the water through hole 4, a gravity block 9 is fixedly connected to the lower end of the adjusting rod 5, a connecting ring 6 is fixedly connected to the upper end of the adjusting rod 5, a second rope 7 is connected to the connecting ring 6, a baffle 8 is fixedly connected to the outer wall of the adjusting rod 5 located in the water sampling bottle 1, the baffle 8 is matched with the water through hole 4, a plurality of baffle bars 10 matched with the water through hole 4 are fixedly connected to the outer wall of the upper end of the adjusting rod 5, when collecting water from a deep water source, the first rope 2 is pulled, the water sampling bottle 1 is thrown into the water, and a gravity block 9 is fixedly connected to the lower end of the adjusting rod 5, a connecting ring 6 is fixedly connected to the upper end of the adjusting rod 5, and a second rope 7 is connected to the connecting ring 6. Driven by the force block 9, the adjusting rod 5 moves downward, and the baffle 10 limits the downward movement distance of the adjusting rod 5. The water inlet hole 3 and the water through hole 4 are connected to the outside. At this time, the water bottle 1 sinks, and the water source enters the water bottle 1 from the water inlet hole 3, and then is discharged from the water through hole 4 until the water bottle 1 sinks to the position where the water depth is required. At this time, the water source in the water bottle 1 is filled with the water source at this depth, and the first rope 2 is loosened and the second rope 7 is pulled. The second rope 7 drives the adjusting rod 5 to rise through the connecting ring 6, so that the gravity block 9 and the baffle 8 respectively block the water inlet hole 3 and the water through hole 4. At this time, the water source in the water bottle 1 cannot flow out, and the second rope 7 is continuously pulled upward to pull the water bottle 1 out of the water, so as to facilitate the collection of water sources in deep water areas without affecting the detection results.

[0024] See also Figure 2 , 4 5. The outer wall of the adjusting rod 5 is fixedly connected with two sealing rings 14 which match the water inlet hole 3 and the water through hole 4 respectively. The sealing ring 14 is set in a trapezoidal shape. When the water sample needs to be retracted after the water sample collection is completed, the two sealing rings 14 are respectively inserted into the water inlet hole 3 and the water through hole 4 to increase the sealing performance of the water inlet hole 3 and the water through hole 4.

[0025] See also Figure 1 , 3 Two connecting blocks 12 are fixedly connected to the upper surface of the water sampling bottle 1, and bolts 13 are connected to the inner threads of the connecting blocks 12. The outer wall of the adjusting rod 5 is provided with a through hole 11 matching the bolt 13. After the water sampling bottle 1 filled with the sampled water source is pulled out of the water, the two bolts 13 are rotated to insert the two bolts 13 into the through hole 11, and the adjusting rod 5 is restricted so that the adjusting rod 5 cannot move downward, so that the water inlet hole 3 and the water through hole 4 remain sealed, which is convenient for taking the water sampling bottle 1 back for testing.

[0026] See also Figure 2 The inner wall of the water bottle 1 is fixedly connected with a stabilizing frame 15, and the adjusting rod 5 passes through the stabilizing frame 15 and is slidably connected thereto. The stabilizing frame 15 restricts the adjusting rod 5 so that the adjusting rod 5 remains stable when moving.

[0027] See also Figure 1-5 The diameter of the water hole 4 is larger than the diameter of the water inlet hole 3 , so that the water entering the water collection bottle 1 from the water inlet hole 3 can be quickly discharged from the water hole 4 .

[0028] Working principle: When collecting water from deep water areas, pull the first rope 2 and throw the water bottle 1 into the water. Driven by the gravity block 9, the adjusting rod 5 moves downward, and the blocking bar 10 limits the downward movement of the adjusting rod 5. The water inlet hole 3 and the water outlet hole 4 are connected to the outside world. At this time, the water bottle 1 sinks, and the water source enters the water bottle 1 from the water inlet hole 3 and then is discharged from the water outlet hole 4 until the water bottle 1 sinks to the position where the water depth is required. At this time, the water bottle 1 is filled with water of the depth, the first rope 2 is released, and the second rope 7 is pulled. The second rope 7 passes through the connecting ring. 6 drives the adjusting rod 5 to rise, so that the gravity block 9 and the baffle plate 8 respectively block the water inlet hole 3 and the water through hole 4, and the two sealing rings 14 are respectively inserted into the water inlet hole 3 and the water through hole 4 to seal them. At this time, the water source in the water sampling bottle 1 cannot flow out, and the second rope 7 can be pulled upward continuously to pull the water sampling bottle 1 out of the water. After the water sampling bottle 1 containing the sampled water source is pulled out of the water, the two bolts 13 are rotated to insert the two bolts 13 into the through hole 11, so as to restrict the adjusting rod 5, so that the adjusting rod 5 cannot move downward, and the water inlet hole 3 and the water through hole 4 can be kept sealed.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
