[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 - 3, a construction site sewage detection sampling device, including a sampling bottle 1 and a bottle cap 11. An internal thread is provided at the top of the inner side wall of the sampling bottle 1, and an external thread is provided on the outer side wall of the bottle cap 11. The external thread of the bottle cap 11 is screwed with the internal thread of the sampling bottle 1. An installation groove is penetrated and opened at the rear side of the top of the bottle cap 11, and a filter screen 13 is fixedly arranged in the installation groove. A sealing plate 2 is placed at the bottom of the bottle cap 11. A water inlet 22 is penetrated and opened at the rear side of the top of the sealing plate 2, and the water inlet 22 corresponds to the filter screen 13. The construction site sewage enters the sampling bottle 1 through the filter screen 13 and the water inlet 22 to complete the sampling. And the filter screen 13 can filter the gravel and stones in the construction site sewage, so as to ensure the quality of the sampled sewage. Sealing gaskets 21 are fixedly arranged on the outer side wall and the top of the sealing plate 2. Among them: A locking component is placed on the top of the sealing plate 2. The outer side wall of the sealing gasket 21 is attached to the inner side wall of the sampling bottle 1, and the top of the sealing gasket 21 is attached to the bottom of the bottle cap 11. The locking component includes a rotating shaft 23. A square groove is opened at the top of the rotating shaft 23, a spring 24 is fixedly arranged at the bottom of the square groove, a square rod 25 is fixedly arranged at the top of the spring 24, a dial 14 is fixedly arranged at the top of the square rod 25, and a plug pin 26 is fixedly arranged at the rear side of the bottom of the dial 14. The rotating shaft 23 is fixedly arranged on the top of the sealing plate 2. A through hole is opened at the top of the bottle cap 11, and the rotating shaft 23 is rotatably arranged in the through hole. The dial 14 is located at the top of the bottle cap 11. Two groups of dial grooves 12 are evenly opened at the top of the bottle cap 11. The bottle cap 11 is screwed into the sampling bottle 1 through the thread. The bottle cap 11 can be rotated through the dial grooves 12, so that the bottle cap 11 and the sealing plate 2 can be taken out, which is convenient for cleaning each component and avoiding pollution when holding other samples later. A second jack 28 is opened at the front side of the top of the bottle cap 11, and a first jack 27 is opened at the rear side of the top of the bottle cap 11. The plug pin 26 is inserted into the first jack 27 and corresponds to the second jack 28. When the sewage sampling is completed, the dial 14 is pulled upward to drive the square rod 25 to move upward, and then drive the plug pin 26 to separate from the first jack 27. At this time, the dial 14 is rotated 180 degrees, and the sealing plate 2 is driven to rotate synchronously through the square rod 25 and the rotating shaft 23, so that the water inlet 22 can be staggered from the filter screen 13, and the filter screen 13 is closed by the sealing plate 2. The sealing gasket 21 can improve the sealing performance of the sealing plate 2 and avoid water leakage. At the same time, the plug pin 26 will be aligned with the second jack 28 as the dial 14 rotates. At this time, the dial 14 is released, and the dial 14 can be driven to move downward and reset through the resilience of the spring 24, and then drive the plug pin 26 to insert into the second jack 28, so as to complete the position locking of the sealing plate 2.
[0021] Working principle: The construction site sewage enters the sampling bottle 1 through the filter 13 and the water inlet 22 to complete the sampling, and the sand and stones in the construction site sewage can be filtered through the filter 13 to ensure the quality of the sampled sewage. When the sewage sampling is completed, pull the dial wheel 14 upward to drive the square rod 25 to move upward, and then drive the latch 26 to separate from the first socket 27. At this time, rotate the dial wheel 14 180 degrees, and drive the sealing plate 2 to rotate synchronously through the square rod 25 and the rotating shaft 23, so that the water inlet 22 and the filter 13 can be staggered, and the filter 13 can be closed through the sealing plate 2, and the sealing gasket 21 can improve the sealing performance of the sealing plate 2 to avoid water leakage. At the same time, the pin 26 will be aligned with the second hole 28 as the dial wheel 14 rotates. At this time, the dial wheel 14 is released, and the rebound force of the spring 24 can drive the dial wheel 14 to move downward and reset, thereby driving the pin 26 to be inserted into the second hole 28, thereby completing the position locking of the sealing plate 2. The bottle cap 11 is screwed into the sampling bottle 1 through a thread, and the bottle cap 11 can be rotated through the dial groove 12, so that the bottle cap 11 and the sealing plate 2 can be taken out, thereby facilitating the cleaning of each component and avoiding contamination when other samples are placed later.
