Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring equipment, specifically to a flow-through pool that facilitates the observation of flow velocity. Background Technology

[0002] A flow cell, also known as a flow cup or flow element, is a crucial structural component widely used in water quality monitoring. Many water quality analyzers have specific requirements regarding the flow rate, pressure, and direction of the water sample. To ensure proper water quality testing, a flow cell matching the analyzer's requirements must be designed. Generally, during monitoring, to guarantee accurate results from various monitoring devices, the flow rate of the water entering the flow cell needs to be maintained within a set range. Therefore, during water quality monitoring, personnel frequently need to monitor the flow rate in the flow cell to ensure it remains stable within the set range. If the flow rate deviates from the range, real-time adjustments are made to ensure accurate results. However, this method of monitoring flow rate is prone to omissions due to personnel negligence and is also quite labor-intensive. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a flow pool that is easy to observe the flow velocity, and to solve the problem that the existing flow pool requires manual timed detection of water flow velocity, which is prone to missed detection and is time-consuming and labor-intensive.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A flow-through tank for easy flow velocity observation includes a tank body with an inlet channel, an outlet channel, and a diversion channel group on the tank body. The inlet and outlet ends of the diversion channel group are respectively connected to the inlet channel and the outlet channel. The tank body is made of transparent material. The diversion channel group includes a first flow channel, a second flow channel, and an outlet channel. The first flow channel and the outlet channel are both vertically arranged and located on the same side of the tank body. The lower end of the first flow channel is connected to the inlet channel. The second flow channel is U-shaped and includes a first vertical flow channel and a second vertical flow channel. The first vertical flow channel is located between the first flow channel and the outlet channel. There is a height difference between the upper end of the first vertical flow channel and the second vertical flow channel. The first vertical flow channel is connected to the second vertical flow channel via a guide channel. The upper end of the second vertical flow channel is connected to the upper surface of the pool body and to the upper ends of the first flow channel and the outlet channel. A float is installed in the first flow channel, which floats after water enters the first flow channel. A plug is installed in the first flow channel above the guide channel to prevent the float from passing through, and the plug has a gap leading to the upper end of the first flow channel. An indicator line is provided on the outer end of the pool body to indicate the floating height of the float at a set flow rate. In this way, the pool body is transparent, allowing a clear view of the water flow in each channel inside, and also facilitating the observation of the float's position. During use, the external water sample to be tested enters the inlet channel through an external pipe, flows to the first flow channel through the inlet channel, then enters the second flow channel through the guide channel, flows through the first and second vertical flow channels in sequence, enters the outlet channel, and finally flows out through the outlet channel. If there is too much water in the sample, the sample will flow through the gap in the plug to the upper end of the first flow channel, overflowing the excess water to the outlet channel. During monitoring, the water quality sensor is installed at the upper end of the second vertical flow channel, with the detection end extending into the second vertical flow channel for real-time monitoring. Because there is a constant height difference between the first and second vertical flow channels in the second flow channel, and the second vertical flow channel opens to the outside, the overall flow velocity of the sample remains stable during the flow process, allowing the float in the first flow channel to remain at a certain height during monitoring. When the inlet water pressure changes, the inlet flow rate changes, but after passing through the flow tank, it can be stabilized to a certain extent to the sensor's flow rate. Therefore, monitoring personnel only need to calculate and determine the range of the float's floating height at the set flow rate. Based on the calculated value, an indicator range line can be set outside the tank. By observing whether the float is within this indicator range line during monitoring, the stability of the flow velocity can be determined. There is no need to continuously monitor the flow velocity of the sample. This detection method is time-saving, labor-saving, and intuitive.

[0006] Furthermore, the indicator lines include a maximum water level line and a minimum water level line, which are either set on a transparent sticker or directly marked on the pool body. In this way, the maximum and minimum water level lines can indicate the floating height of the buoy. Setting the two indicator lines on a transparent sticker and attaching them to the pool body makes them easy to replace and reattach without affecting the observation of the buoy. Marking them directly on the outer surface of the pool body makes them less likely to fall off, but it is inconvenient to adjust their position as needed.

[0007] Furthermore, the second flow channel includes a first vertical flow channel, a second vertical flow channel, and a transverse flow channel, with the transverse flow channel located at the lower end of the first and second vertical flow channels. Thus, the first vertical flow channel, the second vertical flow channel, and the transverse flow channel form a U-shaped flow channel, allowing the water sample to pass sequentially through the first vertical flow channel and the transverse flow channel before flowing into the second vertical flow channel and finally being guided to the outlet flow channel.

[0008] Furthermore, the upper width of the second vertical flow channel is greater than the lower width, and the second vertical flow channel is connected to the outlet channel, as is the connection between the plug of the first flow channel and the outlet channel, via a guide ramp. In this way, once the water level reaches the height of the guide ramp, it is directly discharged into the current flow channel through the guide ramp, resulting in good flow guidance. Simultaneously, the presence of ramps at these two locations disrupts the surface tension of the water sample, preventing the water level at the overflow point from significantly exceeding the overflow level of the flow tank, thus allowing the water to overflow and flow away more quickly.

[0009] Furthermore, the lower end of the first flow channel is connected to the water inlet channel via an L-shaped channel. In this way, after the water inlet connector of the water inlet channel is opened to introduce the sample water to be tested, it enters the first flow channel through the L-shaped channel.

[0018] like Figures 1-6As shown, this embodiment provides a flow tank for easy flow velocity observation, including a tank body 1. The tank body 1 is transparent and is assembled from a top cover, a front main body, and a rear main body. The tank body 1 is provided with an inlet channel 2, an outlet channel 7, and a diversion channel group. The inlet channel 2 and the outlet channel 7 are both located at the lower end of the tank body 1 and are respectively equipped with an inlet connector and an outlet connector. The inlet and outlet ends of the diversion channel group are respectively connected to the inlet channel 2 and the outlet channel 7. The diversion channel group includes a first flow channel 3, a second flow channel 5, and an outlet channel 6. The first flow channel 3 and the outlet channel 6 are both vertically arranged and located on the same side of the tank body 1. The lower end of the first flow channel 3 is connected to the inlet channel 2 through an L-shaped channel. The second flow channel 5 is U-shaped and includes a first vertical flow channel 51 and a second vertical flow channel 52. Two vertical flow channels 53 are provided. The first vertical flow channel 51 is located between the first flow channel 3 and the outlet channel 6, with a height difference between its upper end and the second vertical flow channel 53. The first vertical flow channel 51 and the first flow channel 3 are connected by a guide channel 31. The upper end of the second vertical flow channel 53 is connected to the upper surface of the pool body 1 and to the upper ends of the first flow channel 3 and the outlet channel 6. A float 4 is provided in the first flow channel 3. The float 4 can float in the first flow channel 3 after water enters it. A plug 32 is provided in the first flow channel 3 and above the guide channel 31 to prevent the float 4 from passing through. The plug 32 has a gap leading to the upper end of the first flow channel 3. An indicator line 9 is provided on the outer end face of the pool body 1 to indicate the floating height of the float 4 at a set flow rate. In this way, the pool body 1 is transparent, allowing a clear view of the water flow in each channel inside, and also facilitating the observation of the position of the float 4. During operation, the external water sample to be tested enters the inlet channel 2 through an external pipe, flows through the inlet channel 2 to the first flow channel 3, then through the guide channel 31 to the second flow channel 5, and then flows sequentially through the first vertical flow channel 51 and the second vertical flow channel 53 before entering the outlet channel 6 and finally flowing out through the outlet channel 6. If there is too much water in the sample, the sample will flow through the gap on the plug 32 to the upper end of the first flow channel 3, overflowing the excess water into the outlet channel 6. During monitoring, the water quality sensor is installed at the upper end of the second vertical flow channel 53, with the detection end extending into the second vertical flow channel 53 for real-time detection. Because there is a constant height difference between the first vertical flow channel 51 and the second vertical flow channel 53 in the second flow channel 5, and the second vertical flow channel 53 opens to the outside, the overall flow velocity of the water sample to be tested is kept stable during the flow process, thus allowing the float 4 in the first flow channel 3 to remain at a certain height during the monitoring process. Therefore, monitoring personnel only need to calculate and determine the range of the floating height of the float 4 at the set flow rate. They can then set an indicator range line 9 outside the pool body 1 based on the calculated value. By observing whether the float 4 is within the indicator range line 9 during the monitoring process, they can determine whether the flow rate is stable. There is no need to continuously monitor the flow rate of the water sample to be tested. This detection method is time-saving, labor-saving, and intuitive and simple.

[0019] like Figure 1 As shown, the indicator interval line 9 includes a maximum water level line and a minimum water level line. The indicator interval line 9 is set on a transparent sticker 8, which is affixed to the outer end face of the pool body 1. In this way, the maximum and minimum water level lines can indicate the floating height of the float 4. By setting the two indicator lines on the transparent sticker 8 and affixing it to the side of the pool body 1 near the first flow channel 3, it is easy to replace and re-attach without affecting the observation of the float 4. Of course, in specific implementation, the indicator interval line 9 can be directly displayed on the pool body 1 by drawing or tracing.

[0020] like Figure 5 , Figure 6 As shown, the second flow channel 5 includes a first vertical flow channel 51, a second vertical flow channel 53, and a transverse flow channel 52, with the transverse flow channel 52 located at the lower end of the first vertical flow channel 51 and the second vertical flow channel 53. Thus, the first vertical flow channel 51, the second vertical flow channel 53, and the transverse flow channel 52 form a U-shaped flow channel, allowing the water sample to pass sequentially through the first vertical flow channel 51 and the transverse flow channel 52 before flowing into the second vertical flow channel 53 and finally being guided out of the flow channel.

[0021] Furthermore, the upper width of the second vertical flow channel 53 is greater than the lower width, and the second vertical flow channel 53 is connected to the outlet channel 6, as is the connection between the plug 32 of the first flow channel 3 and the outlet channel 6, via a guide slope. In this way, once the water level reaches the height of the guide slope, it is directly guided to the outlet channel, resulting in good flow guidance. Simultaneously, the slopes at these two locations disrupt the surface tension of the sample water, preventing the water level at the overflow point from significantly exceeding the overflow level of the flow tank, thus allowing the water to overflow and flow away more quickly. Specifically, the guide slope is a chamfered slope, with the lower end inclined towards the outlet channel 6.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
