Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, specifically a portable extractor for sampling water quality at drainage outlets. Background Technology

[0002] Water quality sampling is an important part of environmental monitoring, wastewater treatment, and ecological assessment. In particular, in scenarios such as municipal drainage and industrial wastewater discharge, water samples need to be collected regularly for physicochemical index testing.

[0003] Most common portable water sampling devices currently use a single sampling tube design, which can only collect one water sample at a time. If multiple samples need to be collected, the operation must be repeated many times, which is not only inefficient, but also makes it difficult to ensure the consistency of different sample collection conditions, affecting the comparability of subsequent test data. Utility Model Content

[0004] The purpose of this invention is to provide a portable extractor for sampling water quality at drainage outlets, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A portable extractor for sampling water quality at drainage outlets, comprising: The diverter pipe has a detachable cap at its top, and the cap has a lifting mechanism at its top. A sampling tube is set at the bottom end of the shunt tube with equal curvature, and a disassembly and assembly mechanism is provided between the sampling tube and the shunt tube.

[0006] Preferably, the lifting mechanism includes a sleeve rod vertically fixedly connected to the middle of the top of the tube cap, and a sleeve movably sleeved on the outside of the sleeve rod. The top of the sleeve is fixedly connected to an anti-slip handle, and the bottom of the sleeve is fixedly connected to a damping ring. The outer wall of the sleeve rod slides in cooperation with the inner wall of the damping ring. Preferably, a flow-dividing cavity is formed at the lower part of the flow-dividing pipe, and an annular stepped groove is formed at the top of the flow-dividing pipe at the top of the flow-dividing cavity. A connecting ring is fixedly connected to the bottom end of the pipe cover, and the connecting ring is threadedly connected to the annular stepped groove. Preferably, both sides of the diversion pipe are provided with arc-shaped water inlets, and baffles are fixedly connected to the arc-shaped water inlets on both sides; Preferably, the disassembly and assembly mechanism includes several joints fixedly connected to the bottom end of the diversion tube with equal arc, and a sleeve fixedly connected to the top end of the sampling tube, the sleeve being threaded to the outside of the joints; Preferably, the sampling tube is made of a transparent material.

[0007] Compared with the prior art, the beneficial effects of this utility model are: This portable extractor for sampling water quality at drainage outlets achieves simultaneous and uniform sampling of multiple tubes through the threaded connection of the sampling tube and the diversion tube joint and the sleeve, as well as the combined use of the diversion cavity and the arc-shaped inlet. This solves the problems of low efficiency and poor sample comparability caused by the existing technology that can only collect one water sample at a time.

[0008] This portable extractor for sampling water quality at drainage outlets achieves a compact overall structure, ease of carrying, and rapid assembly through modular and detachable use of a diversion tube, sampling tube, and lifting mechanism. It solves the problems of bulky size and inconvenient field operation of traditional sampling equipment. Attached Figure Description

[0011] 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.

[0012] like Figure 1-4 As shown, this utility model provides a technical solution: A portable water quality sampling device for drainage outlets includes a diversion tube 1, with a cap 2 detachably connected to its top. A lifting mechanism is provided at the top of the cap 2, comprising a sleeve 4 vertically fixedly connected to the middle of the top of the cap 2, and a sleeve 5 movably sleeved outside the sleeve 4. A non-slip handle 6 is fixedly connected to the top of the sleeve 5, and a damping ring 7 is fixedly connected to the bottom of the sleeve 5. The outer wall of the sleeve 4 slides against the inner wall of the damping ring 7. A sampling tube 3 is located at the bottom of the diversion tube 1 with an equal arc. A disassembly and assembly mechanism is provided between the sampling tube 3 and the diversion tube 1 for disassembly and assembly. The mechanism includes several connectors 13 fixedly connected to the bottom end of the diversion pipe 1 with equal arc, and a sleeve 14 fixedly connected to the top end of the sampling pipe 3. The sleeve 14 is threaded to the outside of the connectors 13. A diversion cavity 8 is opened at the bottom of the inside of the diversion pipe 1. An annular stepped groove 9 is opened at the top of the diversion pipe 1 in the diversion cavity 8. A connecting ring 10 is fixedly connected to the bottom end of the pipe cover 2. The connecting ring 10 is threaded to the annular stepped groove 9. Arc-shaped water inlets 11 are opened on both sides of the diversion pipe 1. A baffle 12 is fixedly connected to the arc-shaped water inlets 11 on both sides. The sampling pipe 3 is made of transparent material. In this embodiment, the threaded connection between the sampling tube 3 and the connector 13 and sleeve 14 of the diversion tube 1, as well as the combined use of the diversion cavity 8 and the arc-shaped inlet 11, achieves the effect of simultaneous and uniform sampling of multiple tubes, solving the problems of low efficiency and poor sample comparability caused by only being able to collect one water sample at a time in the prior art.

[0013] Furthermore, by using the modular and detachable combination of the diversion tube 1, sampling tube 3, and lifting mechanism, the overall structure is compact, easy to carry, and quick to assemble, solving the problems of bulky size and inconvenient field operation of traditional sampling equipment.

[0014] Working principle: During sampling, firstly, the sleeves 14 at the top of the sampling tube 3 are threaded and fixed to the connectors 13 at the bottom of the shunt tube 1. Then, the connecting ring 10 at the bottom of the tube cap 2 is threaded and fixed to the annular stepped groove 9 at the top of the shunt tube 1. Next, the sleeve rod 4 is pulled upward from the sleeve 5 by the lifting mechanism. Since the damping ring 7 at the bottom of the sleeve 5 is made of rubber, it can provide appropriate frictional damping, so that the sleeve rod 4 remains stable when pulled out and retracted. The author holds the non-slip handle 6 and places several sampling tubes 3 into the drain outlet to be sampled. The water flow from the drain outlet enters through the arc-shaped inlets 11 on both sides of the diversion pipe 1. The baffle 12 blocks large debris. The water then enters the diversion chamber 8 and is evenly distributed to each sampling tube 3. After sampling is completed, the operator holds the non-slip handle 6 and lifts the entire device out of the water. Since the sampling tubes 3 are made of transparent material, the water sample collection can be observed directly. Finally, the sampling tubes 3 can be unscrewed for individual storage or sent for testing.

[0015] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
