Description

Technical Field

[0001] This utility model relates to the field of water sample monitoring, and in particular to a water sample collection and receiving device and a miniature water quality monitoring station. Background Technology

[0002] In the field of water sampling for water monitoring, there are various methods for collecting water samples. Existing water sampling buckets often have a liquid inlet at the bottom, and a sealing plate that can be pressed tightly against the liquid inlet is placed inside the water sampling bucket. The water sampling bucket is further provided with a handle at the top. Under normal circumstances, to sample a water area, the water sampling bucket is simply placed into the sampling area at a certain speed. The water pressure will push the sealing plate upward away from the liquid inlet, and then the water sample will flow into the water sampling bucket from the liquid inlet. As the water pressure inside the water sampling bucket increases, when the water pressure above the sealing plate is greater than the water pressure below, the sealing plate will be pressed down tightly against the liquid inlet, thereby ensuring the sealing state of the water sampling bucket and realizing water sampling.

[0003] However, after water samples are collected, if the water sampling bucket is opened manually during the collection process, the water sample is easily contaminated; or the entire water sampling bucket needs to be placed into the collection equipment, and then a way needs to be found to open the water sampling bucket to collect the water sample, which then needs to be transferred to the water quality measuring instrument. Therefore, it is not convenient for the final collection of water samples and accurate monitoring. Utility Model Content

[0004] The primary objective of this invention is to provide a water sample collection and receiving device that is structurally sound, easy to assemble, and convenient to collect samples.

[0005] The second objective of this invention is to provide a miniature water quality monitoring station that allows for quick and convenient sampling.

[0006] To achieve the above objectives, this utility model provides a water sample collection and receiving device, including a receiving structure and a corresponding water collection bucket. The receiving structure includes a collection chamber and a receiving pipe communicating with the bottom of the collection chamber. The bottom of the collection chamber is provided with a gradually narrowing drainage funnel, and the drainage port of the drainage funnel is connected to the receiving pipe. The middle of the collection chamber is provided with a longitudinally upward protruding post, which is fixed to a bottom support structure extending inward from the bottom of the collection chamber and supported by the bottom support structure. The minimum diameter of the collection chamber is greater than the maximum diameter of the water collection bucket.

[0007] The water collection bucket has at least one liquid inlet at its bottom, and a water sealing plate that can be pressed tightly against the liquid inlet is placed inside the water collection bucket.

[0008] Furthermore, the liquid collection cavity is a cavity with a circular cross-section.

[0009] Furthermore, the water collection bucket is a cylindrical bucket with a diameter smaller than the diameter of the circular cross-section of the liquid collection chamber.

[0010] Furthermore, the bottom support structure is designed as a cross-shaped structure, that is, two support strips are horizontally intersecting at the bottom of the liquid collection chamber and intersecting at the center, where a longitudinally upward protruding column is fixedly supported.

[0011] Furthermore, the longitudinally upward protruding column is designed as a cross structure, formed by four sequentially perpendicular fin structures.

[0012] Furthermore, inside the water collection tank, several longitudinal guide posts are arranged around the bottom liquid inlet, and a guide space is formed between the several guide posts. The water sealing plate moves up and down within this guide space under force.

[0013] Furthermore, each of the plurality of guide posts is provided with a lateral limiting rod at the same height, and the upward movement height of the sealing plate is limited to the height of the limiting rod.

[0014] A miniature water quality monitoring station, wherein the water sample pool is connected to the receiving pipe of the water sample collection and receiving device of any of the above-mentioned methods.

[0015] Furthermore, the micro water quality monitoring station has a base on its top, and a fixing hole in the middle of the base, to which the liquid receiving structure is longitudinally fixed.

[0016] This patented structure features a rational design, allowing for direct water sample collection after the sampling bucket finishes collecting the sample, eliminating any intermediate transfer steps. Therefore, it significantly improves the efficiency and accuracy of water sample testing. Attached Figure Description

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0024] like Figure 1-3 As shown, a water sample collection and receiving device includes a receiving structure 1 and a corresponding water collection bucket 2.

[0025] The liquid receiving structure 1 includes a liquid collecting chamber 11 and a liquid receiving pipe 13 communicating with the bottom 111 of the liquid collecting chamber 11; the bottom 111 of the liquid collecting chamber 11 is provided with a gradually tightening drain funnel 12, and the drain outlet 121 of the drain funnel 12 is connected to the liquid receiving pipe 13; the middle part of the liquid collecting chamber 11 is provided with a longitudinally upward protruding post 14, and the protruding post 14 is fixed to a bottom support structure 15 extending inward from the bottom 111 of the liquid collecting chamber 11 and supported by the bottom support structure 15; the minimum diameter of the liquid collecting chamber 11 is greater than the maximum diameter of the water collection bucket 2;

[0026] The water collection tank 2 has at least one liquid inlet 21 at its bottom 111, and a water sealing plate 22 that can be pressed and closely attached to the liquid inlet 21 is placed inside the water collection tank 2.

[0027] The liquid collection chamber 11 is a circular cavity. The water collection bucket 2 is a cylindrical bucket, the diameter of which is smaller than the diameter of the circular cross-section of the liquid collection chamber 11.

[0028] like Figure 3 As shown, the bottom support structure 15 is designed as a cross-shaped structure, that is, two support strips 151 are horizontally intersecting at the bottom 111 of the liquid collection chamber 11, and they intersect at the center, where the longitudinally upward protruding column 14 is fixedly supported.

[0029] The longitudinally upward protruding column 14 is designed with a cross-shaped structure, formed by four sequentially perpendicular fin structures 141. The bottom support structure 15 is also designed with a cross-shaped structure, which enhances the support while maintaining a large space for water flow. In addition, the cross-shaped protruding column 14 is stronger than the cylindrical protruding column 14. When the water sampling bucket 2 has collected the water sample to be tested, it is positioned here and lowered. The protruding column 14 will abut against the sealing plate 22, and the sealing plate 22 will be pushed away from the liquid inlet 21. Because the pressure inside the water sampling bucket 2 is relatively large when it is filled with the water sample to be tested, the cross-shaped protruding column 14 can better ensure the strength of the protruding column 14 and is not easily bent under force.

[0030] Inside the water sampling tank 2, several longitudinal guide posts 23 are arranged around the liquid inlet 21 at the bottom 111. These guide posts 23 form a guide space 24, within which the sealing plate 22 moves up and down. This up-and-down movement of the sealing plate 22 within the predetermined guide space 24 ensures that the sealing plate 22 can accurately position and close the liquid inlet 21 during water sampling and collection, thus guaranteeing the accuracy of the water sampling tank 2.

[0031] Each of the guide posts 23 is provided with a lateral limiting rod 231 at the same height, and the upward movement height of the sealing plate 22 is limited to the height of the limiting rod 231. This design ensures that the sealing plate 22 will not deviate from the predetermined vertical movement range.

[0032] like Figure 4-6 As shown, a miniature water quality monitoring station 3 has a water sample pool connected to the liquid receiving pipe 13 of the aforementioned water sample collection and receiving device. Furthermore, the miniature water quality monitoring station 3 has a base 31 on its top, and a fixing hole 311 in the middle of the base 31. The liquid receiving structure 1 is longitudinally fixed to this fixing hole 311.

[0033] In practical use, once the water sampling bucket 2 has collected enough water samples, it can be moved to the top of the micro water quality monitoring station 3, aligned with the protruding post 14, and the water sampling bucket 2 is lowered. The water sealing plate 22 inside the water sampling bucket 2 is pushed open by the protruding post 14, and the water sample inside the water sampling bucket 2 is discharged from the inlet 21. Due to the design of this patent, the lower end of the water sampling bucket 2 is completely covered by the liquid collection chamber 11, and the discharged water sample flows into the drain funnel 12 at the bottom 111 of the liquid collection chamber 11. It is then discharged directly into the receiving pipe 13 through the drain funnel 12 and then into the water sample pool of the micro water quality monitoring station 3. The micro water quality monitoring station 3 performs water sample detection according to the set monitoring program.

[0034] The patented design is reasonable. After the water sampling bucket 2 finishes sampling, the water sample is collected directly without any intermediate transfer process. Therefore, it greatly improves the efficiency and accuracy of water sample testing.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
