Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to a sewage sampling device. Background Art

[0002] Water pollution refers to the pollution caused by industrial wastewater, domestic sewage and other wastes entering rivers, lakes and seas, which exceeds the self-purification capacity of the water. This will lead to changes in the physical, chemical and biological characteristics of the water, thereby affecting the utilization value of water, endangering human health or damaging the ecological environment, and causing water quality deterioration. In order to control water pollution, it is often necessary to sample and test the water.

[0003] The sewage sampler in the prior art requires the staff to hold the sampler for sampling, or use a rope to place the sampler in the water for sampling. The placement of the sampler is prone to tilt under the action of buoyancy, which is inconvenient to operate. Therefore, patent publication number CN206450459U discloses a sewage sampler, which mainly includes a handle, a telescopic bellows is installed at one end of the handle, and a cylindrical sampling tube with an open end is installed at the end of the telescopic bellows.

[0004] With the above-mentioned sampling device, the staff can directly hold the handle to use the sampling tube to draw water. The sampling tube can be tilted by itself to draw water, which is more convenient to operate. However, the telescopic bellows is easy to bend, so the extension distance is limited. When the handle is too long, it is not convenient to store and carry. In addition, a filter is provided on the tube cover to filter floating objects on the water surface. However, after each sampling, the tube cover needs to be unscrewed for water collection and testing, which is not convenient for water collection and testing from the sampling tube. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a sewage sampling device to solve the problems of being inconvenient to store and carry and inconvenient to take water for testing from a sampling tube.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sewage sampling device comprises a sampling barrel, one side of the sampling barrel is fixedly connected to a connecting plate, a telescopic tube is rotatably connected to the connecting plate, a threaded column is fixedly installed on the connecting plate, a nut with a screw ear is threadedly connected to the threaded column, the telescopic tube comprises a sleeve and a movable tube, the movable tube moves in the sleeve, the end of the movable tube is fixedly connected to a fixed plate with a mounting hole, and the fixed plate is rotatably connected to the threaded column.

[0008] Preferably, a tube cover is threadedly installed on the top of the sampling tube, a filter screen is installed inside the tube cover, the filter screen includes a left filter screen and a right filter screen, the left filter screen is hinged on the tube cover, the right filter screen is fixedly installed on the tube cover, and the left side of the left filter screen is clamped on the tube cover.

[0009] Preferably, a clamping block with a clamping slot is fixedly connected to the left side of the left filter screen, a protruding block is fixedly connected to the left side of the cylinder cover, and the clamping block is clamped with the protruding block.

[0010] Preferably, a non-slip grip is installed on the sleeve.

[0011] In summary, the beneficial effects of the utility model are:

[0012] First, the sewage sampling device provided by the utility model has a telescopic tube as a handle, so that the movable tube can move in the sleeve and can be extended to a required length. When sampling, the sampling tube can be tilted to take water by itself, which is more convenient to operate. A fixing plate with a mounting hole can be rotated on the threaded column, so the telescopic tube can be rotated to the required angle for use, and can be easily stored and carried when folded.

[0013] Secondly, by setting a filter screen on the cylinder cover, useless floating objects and other impurities in the sewage can be prevented from entering the sampling bottle. The filter screen is divided into a left filter screen and a right filter screen, wherein the left filter screen can be opened. When it is necessary to extract and test the water in the sampling cylinder, the left filter screen can be directly opened without rotating the entire cylinder cover to open, which makes the operation more convenient and quick.
