Description

Technical Field

[0001] The utility model relates to the field of water quality detection equipment, in particular to a water quality detection sampler. Background Art

[0002] Water treatment in a water plant requires multiple steps to be processed sequentially. For example, in one embodiment, raw water needs to be processed through a high sedimentation tank, ozone, activated carbon, sand filter, and other steps. In order to monitor the quality of water treatment, water samples need to be taken at different water treatment steps.

[0003] At present, water samples from water plants are mostly collected through a hydrological and water quality automatic packaging sampler disclosed in publication number CN221260518U and a detachable and cleanable water sampler disclosed in publication number CN214149968U (hereinafter referred to as comparative document 2). Existing water samplers mostly have an openable and closable valve plate at the bottom of the cylinder. When the sampler is placed in the area to be water-collected, the valve plate moves upward relative to the cylinder of the sampler and opens, and water enters the inner side of the cylinder of the sampler. When the sampler is lifted upward, the valve plate falls and closes.

[0004] Currently, most existing samplers require a valve plate retaining structure inside the barrel, such as the baffle disclosed in Reference 2, to prevent the valve plate from excessive upward movement. Because samplers need to take samples at multiple stages, the interior of the sampler needs to be cleaned after each sampling to prevent cross-contamination of water samples. The retaining structure inside the barrel of existing samplers creates blind spots during cleaning, making it difficult to brush or directly flush the barrel.

[0005] Based on this, the applicant proposed a water quality detection sampler. Utility Model Content

[0025] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0026] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0029] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0030] In this utility model, if Figure 1-4 As shown, a water quality detection sampler is provided, which includes a cylinder 1 with a water cavity, and the bottom wall of the cylinder 1 is provided with a water hole 2. The sampler also includes a valve plate 3 arranged on the inner side of the cylinder 1, a limiter arranged on the lower side of the valve plate 3, and a connecting member connecting the limiter and the valve plate 3, the connecting member passes through the water hole 2, the limiter is arranged on the lower side of the bottom wall, the valve plate 3 can close the water hole 2 when it moves downward to abut against the bottom wall, and the limiter can abut against the bottom surface of the bottom wall when the valve plate 3 moves upward to a set position; wherein, the connecting member is detachably connected to the valve plate 3 and / or the connecting member is detachably connected to the limiter.

[0031] Before the sampler of the present invention is placed in water, the valve plate 3 abuts against the bottom wall. When the cylinder 1 is lowered into the water, the valve plate 3 is pushed upward by the water, and the water sample enters the cylinder 1. At this time, the stopper can be limited by the bottom wall of the cylinder 1 to prevent the valve plate 3 from moving upward excessively. When the cylinder 1 is lifted up after sampling, the valve plate 3 is pressed downward against the bottom wall by the water inside the cylinder 1, so that the water permeable hole 2 is closed.

[0032] When cleaning the sampler after pouring out the water sample in the cylinder 1, you can directly flush into the cylinder 1 and scrub it with a brush. Since there is no limiting structure for the valve plate 3 in the cylinder 1, it is easier to clean the inner side wall and the inner side of the bottom wall of the cylinder 1, so that the cylinder 1 can be cleaned more conveniently and thoroughly. In some embodiments, the connecting part can also be separated from the valve plate 3 or the connecting part can be separated from the limiting part. At this time, the valve plate 3 can be taken out from the inside of the cylinder 1 for cleaning.

[0035] As shown in the figure, a combination of multiple connecting ribs 4 can form a guide structure between the edges of the water hole 2, thereby guiding the valve plate 3 to move up and down, thereby ensuring the sealing effect of the water hole 2 when the valve plate 3 falls and abuts the bottom wall.

[0036] By adopting a combination of more than three connecting ribs 4 , the set center of the circle can be moved within a set area in the water permeable hole 2 , thereby limiting the lateral movement range of the valve plate 3 .

[0037] In a preferred embodiment, for the structure of the present invention, to be more specific, the distance between the outer edge of at most one of the connecting ribs 4 and the set center of the circle is equal to the radius of the water-permeable hole 2 .

[0038] By such an arrangement, the number of the connecting ribs 4 that are in contact with the edge of the water hole 2 at the same time can be reduced, so that the connecting ribs 4 can move back and forth in the water hole 2 more smoothly.

[0045] By providing the limiting protrusion 8 , it is easy to locate the position of the limiting rib 7 when installing the limiting rib 7 .

[0046] In a preferred embodiment, for the structure of the present invention, to be more specific, the connecting rib 5 includes three sections of divided plate bodies, and the inner ends of the three sections of divided plate bodies are connected; when the limiting rib rod 7 is connected to the connecting rib 5, the two sides of at least one of the divided plate bodies are respectively in contact with one of the limiting protrusions 8.
