Description

Technical Field

[0001] This utility model relates to the technical field of water sample testing equipment, specifically to a wastewater testing device that facilitates sampling. Background Technology

[0002] With the acceleration of industrialization and the increasing prominence of environmental pollution, wastewater testing has become an important part of environmental monitoring, sewage treatment, and water quality management.

[0003] Traditional wastewater testing methods typically rely on manual sampling, where staff travel to designated areas (such as urban sewers or sewage treatment plants) to collect water samples, which are then brought back to the laboratory for analysis. However, the process from sampling to testing involves transportation and preservation, inevitably resulting in time delays. Furthermore, microorganisms in the water (such as bacteria) are susceptible to inactivation, death, or metabolic changes due to separation from their original environment, leading to test results that fail to accurately reflect the actual condition of the water body. Additionally, some chemical indicators (such as dissolved oxygen and pH) may fluctuate over time, reducing the accuracy of the tests. Therefore, we propose a wastewater testing device that facilitates convenient sampling to address these issues. Utility Model Content

[0006] A water collection cylinder, wherein a detection instrument is installed in a circular array on the top side of the water collection cylinder, and the detection end of the detection instrument extends into the interior of the cylinder;

[0007] A pumping mechanism is used to pump wastewater into the installation cylinder. The pumping mechanism includes a self-priming pump installed at the bottom of the collection cylinder. The inlet end of the self-priming pump is connected to an inlet pipe, and the end of the inlet pipe away from the self-priming pump is connected to a tennis ball.

[0008] A storage component is disposed inside the water collection cylinder, and the storage component is used to store the water inlet pipe.

[0009] Furthermore, a storage battery is installed above one side of the water collection cylinder, and the input terminals of the detection instrument and the self-priming pump are electrically connected to the output terminals of the storage battery.

[0010] Furthermore, a drain pipe is connected to one bottom side of the water collection cylinder, and a valve is installed on the body of the drain pipe.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This application provides a convenient wastewater sampling device, mainly to address the problems in existing technologies where water samples undergo transportation and storage, inevitably resulting in time delays. Furthermore, microorganisms (such as bacteria) in the water are prone to inactivation, death, or metabolic changes due to separation from their original ecological environment, leading to test results that cannot accurately reflect the actual condition of the water body. Additionally, some chemical indicators (such as dissolved oxygen and pH) may fluctuate over time, reducing the accuracy of the detection. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0024] A wastewater testing device for convenient sampling, comprising:

[0025] A water collection cylinder 1 is provided. A detection instrument 2 is installed in a circular array on the top side of the water collection cylinder 1. The detection end of the detection instrument 2 extends into the interior of the cylinder. A drain pipe 6 is connected to the bottom of one side of the water collection cylinder 1. A valve is installed on the body of the drain pipe 6.

[0026] The pumping mechanism 3 is used to pump wastewater into the installation cylinder. The pumping mechanism 3 includes a self-priming pump 301 installed at the bottom of the water collection cylinder 1. The inlet end of the self-priming pump 301 is connected to an inlet pipe 302, and the end of the inlet pipe 302 away from the self-priming pump 301 is connected to a tennis ball 303.

[0027] Storage component 4 is located inside water collection cylinder 1 and is used to store water inlet pipe 302.

[0028] Workflow Description

[0029] The tennis ball 303 of the device is placed into the water area to be tested. The self-priming pump 301 is turned on, and the water sample is pumped into the water collection cylinder 1 through the inlet pipe 302. After the water sample is filtered by the tennis ball 303, it enters the water collection cylinder 1. The testing instrument 2 (such as pH meter, dissolved oxygen sensor, etc.) performs real-time testing on the water sample. After the test is completed, the self-priming pump 301 is turned off. The inlet pipe 302 is rolled up by the storage component 4 to avoid pipe tangling. The residual water sample in the water collection cylinder 1 is discharged through the drain pipe 6 for the next use.

[0030] It should be noted that this device uses a self-priming pump 301 for water pumping. The self-priming pump 301 needs to be filled with water for the first start-up, but no water filling is required for subsequent starts. Once there is water in the pump body, it can be pumped directly when restarted without repeated filling. Since there will be residual water when using it again (clean water used to clean the pump body, which will affect the pH value test), before testing, the drain pipe 6 valve can be kept open to completely drain the clean water used to clean the pump body. Then the drain pipe 6 valve can be closed for a new round of testing. In addition, the suction head of the self-priming pump 301 varies depending on the pump type and performance. If the water source is lower than the pump body and the height difference is within the suction head range, it can pump water normally. If the height difference is too large, the pump body cannot form sufficient negative pressure, which will result in no water being pumped or insufficient flow.

[0031] The wastewater testing device integrates a self-priming pump 301 and a testing instrument 2, enabling simultaneous "sampling-testing" and eliminating the time difference in water sample transportation. This avoids microbial inactivation and fluctuations in chemical indicators (such as dissolved oxygen and pH), and the test results are closer to the actual state of the water body. The storage component 4 can retract the inlet pipe 302, making it convenient for manual pipe management and improving operational efficiency.

[0032] like Figure 4 As shown, in some embodiments, a storage battery 5 is installed above one side of the water collection cylinder 1. The input terminals of the detection instrument 2 and the self-priming pump 301 are electrically connected to the output terminal of the storage battery 5. More specifically, the storage battery 5 is the core power supply module of the entire device, responsible for providing DC power to the detection instrument 2 (such as sensors and analyzers) and the self-priming pump 301, ensuring that the equipment operates normally in the field or in complex environments without external power.

[0033] like Figure 4 As shown, in some embodiments, the storage component 4 includes a storage tube 401 fixedly embedded in the middle of the water collection tube 1. The top of the storage tube 401 is an open structure, and a fixing rod 402 is fixedly provided on the inner bottom wall of the storage tube 401. The water inlet pipe 302 is wound around the surface of the fixing rod 402. More specifically, the top of the storage tube 401 adopts an open structure, presenting an open opening, which facilitates the insertion and removal of the water inlet pipe 302. The water inlet pipe 302 is wound around the surface of the fixing rod 402 in a winding manner. This winding method allows the water inlet pipe 302 to be neatly stored when not in use, avoiding the water inlet pipe 302 being placed messily in the water collection tube 1. This not only saves space, but also prevents the water inlet pipe 302 from being accidentally hooked, torn, or damaged. When the water inlet pipe 302 is needed, the coiled part can be easily unwound from the fixing rod 402, and the appropriate length of the water inlet pipe 302 can be pulled out for use according to actual needs. After use, it can be coiled back onto the fixing rod 402 to restore the storage state.

[0034] like Figure 4 As shown, in some embodiments, a fixing block 403 is connected to the top of the fixing rod 402. The fixing block 403 has a slot in the middle, which is hourglass-shaped. More specifically, the end of the water inlet pipe 302 passes through the hourglass-shaped slot from one side of the fixing block 403. Because the middle of the slot is narrow, the water inlet pipe 302 will be slightly squeezed and deformed (such as the hose can be slightly reduced in diameter), thereby forming a tight fit with the inner wall of the slot. After the water inlet pipe 302 passes through the slot, the tennis ball 303 is blocked by the slot and sticks to the outside of the slot. Due to the hourglass structure of the slot, the tennis ball 303 cannot be pulled back along the water inlet pipe 302 or leave the fixing block 403, thereby limiting the tennis ball 303 and preventing it from moving.

[0035] like Figure 4As shown, in some embodiments, a counterweight ball 304 is embedded inside the tennis ball 303. The counterweight ball 304 is a solid stainless steel ball. More specifically, by embedding the counterweight ball 304 inside, the weight at the end of the water inlet pipe 302 is increased, ensuring that the water inlet pipe 302 sinks naturally underwater or remains stable.

[0036] like Figure 4 As shown, in some embodiments, a handle 7 is hinged to the top side of the water collection cylinder 1, and a rubber sleeve is fitted on the surface of the handle 7. More specifically, the hinge design of the handle 7 and the anti-slip properties of the rubber sleeve together improve the portability of the water collection cylinder 1. When carrying the water collection cylinder 1 by the handle 7, the risk of slipping caused by directly grasping the surface of the water collection cylinder 1 (such as smooth metal or plastic material) is avoided, and the friction or bumps on the body of the water collection cylinder 1 are reduced.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
