Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling technology, specifically to a sampling device for outdoor wastewater testing. Background Technology

[0002] When conducting water sampling and testing outdoors, samples are taken from the surface of the water. However, for deeper water bodies with obvious stratification, it is necessary to sample different depths of water. This requires inserting the sampler deep into the water body to take samples. To facilitate outdoor shoelaces and allow sampling of deeper water bodies, this invention proposes a sampling device for outdoor wastewater testing. Summary of the Invention

[0003] The purpose of this invention is to provide a sampling device for outdoor wastewater testing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an outdoor wastewater sampling device, comprising a gripping part, a middle part, and a sampling part. The bottom of the gripping part can be threadedly connected to the top of the middle part. The top and bottom of the sampling part can be threadedly connected to the bottom and top of the middle part, respectively. A sampling groove is provided inside the sampling part. Openings communicating with the outside are provided on both sides of the sampling groove. Two sliders are slidably arranged inside the sampling groove. The two sliders are connected by a connecting column. A push rod is fixedly connected to one end of the two sliders that is far apart from each other. The push rod is slidably connected to the sampling part. A groove is provided on the top of the sampling part.

[0005] Preferably, a pressure rod is slidably disposed on the gripping part, penetrating the top and bottom of the gripping part; a central rod is slidably disposed within the middle part, penetrating the top and bottom of the middle part; and a groove is formed at the top of the middle part. The connections between the central rod and the push rod and the middle part and the sampling part are not airtight, allowing gas to pass through to maintain internal pressure balance.

[0006] Preferably, a sealing rubber ring is provided on the side wall of the slider that contacts the sampling groove, and the length of the slider is greater than the length of the opening. The sealing rubber ring is used to prevent gas and liquid from passing through the gap between the slider and the inner wall of the sampling section.

[0007] Preferably, a sealing box is screwed to the bottom of the sampling section, and an elastic rubber membrane is provided at the bottom of the sealing box.

[0008] Among them, the pressure rod is slidably connected to the gripping part, the middle rod is slidably connected to the middle part, and the push rod is slidably connected to the sampling part. In the above sliding connection relationship, the static friction between the two parties in the vertical state can keep them relatively stationary when no external force is applied. At the same time, when the middle part, gripping part and sampling part are connected end to end, the pressure rod, middle rod and push rod are on the same vertical line.

[0009] Compared with the prior art, the beneficial effect of this utility model is that multiple intermediate parts and sampling parts are connected end to end according to the depth to be sampled and extended into the wastewater, which facilitates sampling of wastewater at different depths.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Referring to Figures (1-4), an outdoor wastewater sampling device includes a gripping part 1, a middle part 2, and a sampling part 3. The bottom of the gripping part 1 can be threadedly connected to the top of the middle part 2. The top and bottom of the sampling part 3 can be threadedly connected to the bottom and top of the middle part 2, respectively. A sampling groove 31 is provided inside the sampling part 3. Openings 32 communicating with the outside are provided on both sides of the sampling groove 31. Two sliders 4 are slidably arranged inside the sampling groove 31. The two sliders 4 are connected by a connecting post 41. A push rod 42 is fixedly connected to one end of the two sliders that are far apart from each other. The push rod 42 is slidably connected to the sampling part 3. A groove is provided on the top of the sampling part 3.

[0017] A pressure rod 11 is slidably disposed on the gripping part 1, penetrating the top and bottom of the gripping part 1. A central rod 21 is slidably disposed inside the middle part 2, penetrating the top and bottom of the middle part 2. A groove is formed at the top of the middle part 2. A sealing rubber ring is provided on the side wall of the slider 4 that contacts the sampling groove 31. The length of the slider 4 is greater than the length of the opening 32. A sealing box is screwed to the bottom of the sampling part, and an elastic rubber membrane is provided at the bottom of the sealing box.

[0018] In use, the top of the middle part 2 is connected to the bottom of the gripping part 1, and the top of the sampling part 3 is connected to the bottom of the middle part 2. At this time, the slider 4 in the sampling part 3 is positioned above the sampling groove 31. Under the action of friction between the slider 4 and the sampling groove 31, the slider 4 remains relatively stationary within the sampling groove 31. Then, the connected sampling device is inserted into the wastewater, and the pressure rod 11 is pressed down. The pressure rod 11 pushes the middle rod 21 downward, which in turn pushes the lower push rod 42 downward, transmitting the thrust downward. The sliders in each sampling slot slide downwards under the action of the thrust. When the gap between the two sliders is displaced to the position of the opening 32, the wastewater enters the sampling slot 31 from the opening 32 and into the gap between the two sliders. Then the sliders continue to slide down and return to the position of the opening 32 to prevent the wastewater from entering the sampling slot 31. The sampled wastewater is retained in the gap between the two sliders. Then the entire sampling device is taken out and each sampling part is removed. To remove the wastewater, the push rod can be pushed to push the gap between the sliders to the opening to pour out the wastewater.

[0019] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
