Description

Technical Field

[0001] This utility model relates to the field of pipeline water quality testing technology, specifically to an auxiliary device for single-pipe water quality testing. Background Technology

[0002] Among existing online water quality testing technologies, the most common approach is to use a "bypass testing" scheme. The basic working principle of this mode is: a small portion of the water flow is diverted from the main pipeline and guided to a larger testing chamber or pool that is independent of the main pipeline. After the water flow velocity stabilizes and tends to be still or slow, it is then detected by sensors installed in the chamber.

[0003] Such bypass detection systems typically require complex piping connections, including components such as diversion valves, booster pumps, flow meters, and return pipes, resulting in a large overall system size and inconvenient installation. Furthermore, placing the detection chamber inside the main pipe presents the challenge of dealing with the high water flow velocity in the main pipeline and the instability of direct measurement data. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a single-tube water quality testing auxiliary device.

[0005] The objective of this utility model can be achieved through the following technical solutions: A single-tube water quality testing auxiliary device, comprising: The pipeline body and the detection cavity disposed on the pipeline body; One side of the detection chamber is inserted into the main body of the pipe. The detection chamber includes a buffer flow channel, a water storage chamber disposed inside the detection chamber, and a circulation hole. The buffer channels are long and narrow and are provided in multiple ways. All of the buffer channels are connected to the water storage chamber. The detection device is located in the water storage chamber. The circulation hole is configured on the detection chamber to allow water exchange between the water storage chamber and the main pipe body.

[0006] As a further embodiment of this utility model: the detection cavity includes a mounting component, a mating component, and a connecting plate connecting the mounting component and the mating component, the water storage cavity is disposed inside the mating component, the mating component is cylindrical, and the buffer flow channel is parallel to the outer surface of the mating component.

[0007] As a further embodiment of this utility model: multiple connecting plates are provided, and the multiple connecting plates are distributed at equal intervals around the outer side of the mating part, and the outer wall of the mating part, the inner wall of the mounting part, and two adjacent connecting plates form a single buffer flow channel.

[0008] As a further embodiment of this utility model: the mating component has a baffle plate that extends out of the opening side of the mounting component.

[0009] As a further embodiment of this utility model: the buffer channel with its opening facing the direction of liquid impact inside the pipe body is the inlet channel, and the buffer channel with its opening direction in the same direction as the liquid inside the pipe body is the outlet channel.

[0010] As a further embodiment of this utility model: the baffle gradually extends outward from the side away from the mounting component, and the cross-section of the baffle is arc-shaped.

[0011] As a further embodiment of this utility model: a through groove is provided on the main body of the pipe, and a saddle is detachably connected to the main body of the pipe by bolts, and the detection cavity is detachably connected to the saddle.

[0012] As a further embodiment of this utility model: the mounting component is threadedly connected to the saddle.

[0013] As a further embodiment of this utility model: the saddle includes a sealing ring, the outer wall of which is in close contact with the inner wall of the through groove.

[0014] As a further embodiment of this utility model, the mounting component is wider at the top and narrower at the bottom.

[0015] The beneficial effects of this utility model are as follows: This utility model places the detection chamber directly inside the main body of the pipeline and uses multiple buffer channels arranged around it to effectively slow down the water flow in the main pipeline. Before entering the water storage chamber, the water flow passes through the narrow buffer channels to eliminate turbulence. The water storage chamber provides a relatively flat measurement space for the detection equipment, ensuring that the detection equipment works under stable conditions. At the same time, the circulation hole realizes the slow exchange of water inside and outside the chamber, so that the water sample collected can represent the actual water quality of the main pipeline.

[0016] This invention directly replaces the complex diversion components required for traditional bypass testing by directly installing it on the pipe to be measured, making the system structure compact, easy to install, and significantly reducing equipment costs. Furthermore, through the cooperation of multiple buffer channels and water storage chambers, it overcomes the problem of unstable direct measurement data caused by placing the detection chamber inside the main pipe due to the high water flow velocity in the main pipe, thus simultaneously ensuring the accuracy and reliability of the detection data.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-3 An embodiment of the present invention provides a single-pipe water quality testing auxiliary device, comprising: a pipe body 1 and a testing cavity 2 disposed on the pipe body 1; one side of the testing cavity 2 is inserted into the pipe body 1, and the testing cavity 2 includes a buffer channel 21, a water storage cavity 22 disposed inside the testing cavity 2, and a circulation hole 23; wherein, the buffer channel 21 is long and narrow and is provided in multiple ways, and the multiple buffer channels 21 are all connected to the water storage cavity 22, the testing device is disposed in the water storage cavity 22, and the circulation hole 23 is disposed on the testing cavity 2 to facilitate water exchange between the water storage cavity 22 and the pipe body 1.

[0022] Specifically, when this device is working, the water in the main body of the pipe 1 enters the water storage chamber 22 through the buffer channel 21 facing the direction of water flow, and slowly merges with the water in the water storage chamber 22. Then, it flows away from the water storage chamber 22 through the buffer channel 21 in the direction of water flow. At the same time, the water in the water storage chamber 22 flows into the interior of the main body of the pipe 1 through the circulation hole 23 to form a decelerated circulation.

[0023] Furthermore, this utility model places the detection chamber 2 directly inside the main body of the pipe 1, and uses multiple buffer channels 21 arranged around it to effectively slow down the water flow in the main pipe. Before entering the water storage chamber 22, the water flow passes through the narrow buffer channels 21 to eliminate turbulence. The water storage chamber 22 provides a relatively flat measurement space for the detection equipment, ensuring that the detection equipment works under stable conditions. At the same time, the circulation hole 23 realizes the slow exchange of water inside and outside the chamber, so that the water sample collected can represent the actual water quality of the main pipe.

[0024] This invention directly replaces the complex diversion components required for traditional bypass testing by directly installing it on the pipe to be measured, making the system structure compact, easy to install, and significantly reducing equipment costs. Furthermore, through the cooperation of multiple buffer channels 21 and water storage chambers 22, it overcomes the problem of unstable direct measurement data caused by placing the detection chamber 2 inside the main pipe due to the high water flow velocity in the main pipe, thus simultaneously ensuring the accuracy and reliability of the detection data.

[0025] See Figures 1-3 Optionally, the detection chamber 2 includes a mounting part 24, a mating part 241, and a connecting plate 242 connecting the mounting part 24 and the mating part 241. The water storage chamber 22 is disposed inside the mating part 241. The mating part 241 is cylindrical. The buffer flow channel 21 is parallel to the outer surface of the mating part 241, so that the high-speed water flow entering from the pipe body 1 is forced to change direction, transforming from radial impact into an orderly axial flow parallel to the axis of the mating part 241.

[0026] In this embodiment, the mating component 241 is fixedly installed on the inner side of the mounting component 24 by the connecting plate 242. The cylindrical shape of the mating component 241 and the design of the buffer flow channel 21 being parallel to the outer surface of the mating component 241 greatly reduce the degree of fluid turbulence and significantly slow down the liquid flow rate.

[0027] See Figure 3 Optionally, multiple connecting plates 242 are provided, and the multiple connecting plates 242 are distributed at equal intervals around the outer side of the mating part 241. The outer wall of the mating part 241, the inner wall of the mounting part 24, and two adjacent connecting plates 242 form a single buffer flow channel 21.

[0028] In this embodiment, multiple connecting plates 242 with equal spacing are divided to form multiple fluid channels that are evenly distributed around the mating part 241, so that the water flow is evenly distributed when entering the buffer channel 21, avoiding excessive local pressure.

[0029] See Figures 1-3 Optionally, the mating part 241 has a baffle 241a that extends out of the opening side of the mounting part 24.

[0030] In this embodiment, the baffle 241a extending out of the opening side of the mounting member 24 can change the water flow path, allowing the water to enter the buffer channel 21 more smoothly.

[0031] See Figures 1-3 Optionally, the buffer channel 21 with its opening facing the direction of liquid impact inside the pipe body 1 is the inlet channel 211, and the buffer channel 21 with its opening direction in the same direction as the liquid inside the pipe body 1 is the outlet channel 212.

[0032] In this embodiment, the evenly distributed arrangement of multiple buffer channels 21 eliminates the need for staff to carefully distinguish between the inlet channel 211 and the outlet channel 212 during installation. After the detection chamber 2 extends into the inner side of the pipe body 1, the inlet channel 211 and the outlet channel 212 are naturally divided according to the water flow direction. Utilizing fluid inertia, the inlet channel 211 captures and slows down the high-speed water flow, while the outlet channel 212 releases the water flow at a lower speed, ensuring the renewal of the water sample in the water storage chamber 22 and minimizing the interference of the water flow on the detection equipment.

[0033] See Figures 1-3 Optionally, the side of the baffle 241a away from the mounting member 24 gradually extends outward, and the cross section of the baffle 241a is arc-shaped.

[0034] In this embodiment, when the water flow impacts the baffle 241a, the arc-shaped surface guides the water flow to smoothly change direction, reducing resistance.

[0035] See Figures 1-2 Optionally, a through groove 11 is provided on the main body of the pipe 1, and a saddle 25 is detachably connected to the main body of the pipe 1 by bolts, and the detection chamber 2 is detachably connected to the saddle 25.

[0036] In this embodiment, during installation, the saddle 25 is first fixedly installed on the pipe body 1 with bolts, and then the detection chamber 2 is inserted into the inside of the pipe body 1 and installed on the saddle 25. The detachable design of the saddle 25 and the detection chamber 2 allows for quick installation and disassembly, which is convenient for maintenance or replacement of the detection equipment.

[0037] See Figures 1-2 Optionally, the mounting piece 24 is threaded onto the saddle 25.

[0038] In this embodiment, the mounting component 24 is threadedly connected to the saddle 25. Rotating the mounting component 24 can fix it or remove it from the saddle 25, thereby achieving rapid fixation and sealing of the detection cavity 2.

[0039] See Figures 1-2 Optionally, the saddle 25 includes a sealing ring 251, the outer wall of which is in close contact with the inner wall of the through groove 11.

[0040] In this embodiment, the sealing ring 251 is used to ensure the sealing of the connection between the pipeline body 1 and the detection chamber 2 and to maintain the internal pressure of the pipeline.

[0041] See Figures 1-3 Optionally, mounting piece 24 is wider at the top and narrower at the bottom.

[0042] In this embodiment, during installation, the wider part is easier to operate and position, while the narrower part is embedded in the saddle 25 or the pipe body 1. The wider part can also play a certain sealing role between the mounting part 24 and the saddle 25.
