Description

Technical Field

[0001] This utility model relates to the technical field of drinking water joint testing, and in particular to a portable device for joint testing of residual chlorine and turbidity in drinking water. Background Technology

[0002] Drinking water refers to water that meets national health standards and can be directly consumed by humans or used in daily life. It is generally produced by disinfecting river or groundwater to make it suitable for daily life. However, after treatment, the water needs to be tested for residual chlorine and turbidity using testing equipment.

[0003] Existing portable testing equipment requires removing the sample container from the instrument, extracting the sample, and then inserting the probe into the sample for testing. This process makes the sample susceptible to contamination and results in poor performance. Furthermore, while laser probes are typically used for water turbidity testing, the sample is exposed to the external environment during testing, making it susceptible to light interference that affects accuracy and results in poor performance.

[0004] To address this, we designed a portable device for the combined measurement of residual chlorine and turbidity in drinking water to meet the needs of practical applications. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a portable device for the combined measurement of residual chlorine and turbidity in drinking water.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a portable device for measuring residual chlorine and turbidity in drinking water, including a shell, a receiving groove on one side of the shell, at least two elastic tube clamps installed inside the receiving groove, a sample tube between each elastic tube clamp, and the bottom of the sample tube connected to a pipe joint fixed to the bottom of the receiving groove, the other end of the pipe joint extending to the bottom of the shell.

[0008] A laser probe is installed on the side of the receiving tank. One end of the laser probe is aligned with the side of the sample tube. Each sample tube has a cap at the top, and a detection probe is installed at the bottom of each cap. The detection probe extends into the corresponding sample tube.

[0009] The top of the outer shell is also provided with a receiving cavity, and a negative pressure pump is installed inside the receiving cavity. The air inlet of the negative pressure pump is connected to an adsorption tube, and the other end of the adsorption tube is connected to at least two diversion tubes. The other end of each diversion tube passes through the bottom of the receiving cavity and is fixed to the top of the tube cover. An exhaust pipe is connected to the air outlet of the negative pressure pump, and one end of the exhaust pipe extends to the outside of the outer shell.

[0010] A groove is provided at the bottom of the receiving groove, and a light-shielding plate is rotatably connected inside the groove. The light-shielding plate covers the opening of the receiving groove, and the edge of the light-shielding plate is sealed to the side wall of the receiving groove.

[0011] To be more specific, each pipe joint has a suction pipe connected to its bottom end.

[0012] In detail, the top side of the receiving groove has several openings, and magnetic blocks are installed in the openings. A strip connecting piece is installed on the top of the light-shielding plate. When the light-shielding plate covers the opening of the receiving groove, the strip connecting piece moves into the opening and is attracted and fixed to the magnetic blocks.

[0013] In detail, the side of the magnetic block is flush with the opening end of the slot.

[0014] In detail, the light-blocking panel is made of opaque plastic.

[0015] To be more specific, an electrically controlled valve is installed at one end of the adsorption tube.

[0016] In detail, the outer shell also has an installation cavity, inside which a control main board is installed. The control main board is connected to the detection probe, negative pressure pump, laser probe and electric control valve through wires.

[0017] In detail, a battery is installed inside the cavity, and the battery is connected to the control board via wires.

[0018] Core Function: During testing, the operator installs the suction tube on the pipe connector and inserts the other end of the suction tube into the drinking water. The main control board then activates the negative pressure pump, which draws air out of the sample tube through the adsorption tube and the diversion tube, creating negative pressure within the sample tube. This suction force draws the drinking water into the sample tube. Once the water level in the sample tube reaches a preset value, the operator shuts off the negative pressure pump and the electronically controlled valve via the main control board. The operator then rotates the light-shielding plate, covering the opening of the receiving slot, causing the magnetic block to adhere and fix the strip connecting piece, thus securing the light-shielding plate. The operator then controls the laser probe and detection probe via the main control board to detect residual chlorine and turbidity in the sample and transmits the detection data to the main control board. The main control board processes the data and displays it on the screen on the outer casing for the operator to view, thus completing the testing with high accuracy.

[0019] The design scheme proposed in this utility model has the following beneficial effects in application:

[0020] 1. External drinking water can be directly drawn into the sample tube by a negative pressure pump, and then detected by a laser probe and a detection probe. There is no need to remove the sample tube to collect the sample, and the sample will not be contaminated during the collection process, thus improving the effectiveness of use.

[0021] 2. The light shield can block the opening of the receiving slot, so that the sample tube is in a closed space. This way, external light will not shine on the sample inside the sample tube, and the laser probe will not be hindered by external light during detection, thus improving the performance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 A portable device for measuring residual chlorine and turbidity in drinking water includes a housing 1. An installation cavity 19 is provided inside the housing 1. A control main board 18 is installed inside the installation cavity 19. The control main board 18 is either a PCB circuit board or a microcontroller circuit board. A receiving groove 15 is provided on one side of the housing 1. At least two elastic tube clamps 6 are installed inside the receiving groove 15. A sample tube 11 is provided between each elastic tube clamp 6, and the bottom of the sample tube 11 is connected to a pipe connector 20 fixed to the bottom of the receiving groove 15. The other end of the pipe connector 20 extends to the bottom of the housing 1. A water suction tube 9 is connected to the bottom end of each pipe connector 20. In actual use, the sample tube 11 can be clamped and fixed by the elastic tube clamps 6, thus preventing the sample tube 11 from falling and being damaged.

[0029] like Figure 2 and Figure 4As shown, each sample tube 11 is equipped with a tube cap 13 at the top. The top of the outer shell 1 is also provided with a receiving cavity 21. A negative pressure pump 16 is installed inside the receiving cavity 21. The air inlet of the negative pressure pump 16 is connected to an adsorption tube 14. The other end of the adsorption tube 14 is connected to at least two diversion tubes 5. The other end of each diversion tube 5 passes through the bottom of the receiving cavity 21 and is fixed to the top of the tube cap 13. An exhaust pipe 3 is connected to the air outlet of the negative pressure pump 16. One end of the exhaust pipe 3 extends to the outside of the outer shell 1. The negative pressure pump 16 is connected to the control main board 18 through a wire. In actual use, the staff puts one end of the water suction tube 9 into drinking water. Then, the negative pressure pump 16 can suck out the air in the sample tube 11, so that a negative pressure is formed in the sample tube 11. In this way, the drinking water will be sucked into the sample tube 11 through the water suction tube 9, thus completing the collection.

[0030] It should be noted that, as Figure 4 As shown, an electric control valve 22 is installed at one end of the adsorption tube 14. The electric control valve 22 is connected to the control main board 18 through a wire. In actual use, when the sample drinking water sample reaches a preset height in the sample tube 11, the staff can close the electric control valve 22 through the control main board 18 to close the adsorption tube 14. In this way, the sample will stay in the sample tube 11 and will not flow out.

[0031] like Figure 2 and Figure 3 As shown, a laser probe 17 is installed on the side of the receiving tank 15, with one end of the laser probe 17 aligned with the side of the sample tube 11. A detection probe 12 is installed at the bottom of each tube cap 13, extending into the corresponding sample tube 11. The laser probe 17 and the detection probe 12 are connected to the control main board 18 via wires. In actual use, the residual chlorine in the drinking water sample in the sample tube 11 can be detected by the detection probe 12, while the laser emitted by the laser probe 17 can detect the turbidity of the drinking water. The detection data is transmitted to the control main board 18, and then the data is processed and displayed on the display screen on the outer casing 1.

[0032] like Figure 1 As shown, a groove 10 is provided at the bottom of the receiving groove 15. A light shield 7 is rotatably connected inside the groove 10. The light shield 7 covers the opening of the receiving groove 15, and the edge of the light shield 7 is sealed to the side wall of the receiving groove 15. The light shield 7 is made of opaque plastic. In this way, when conducting the test, the staff can cover the opening of the receiving groove 15 with the light shield 7 to block the external light and avoid the external light from interfering with the detection of the laser probe 17.

[0033] It should be further explained that, such as Figure 1As shown, a plurality of openings 4 are provided on one side of the top of the receiving groove 15. Magnetic blocks 2 are installed in the openings 4. A strip connecting piece 8 is installed on the top of the light-shielding plate 7. When the light-shielding plate 7 covers the opening of the receiving groove 15, the strip connecting piece 8 moves into the opening 4 and is attracted and fixed to the magnetic blocks 2. The side of the magnetic blocks 2 is flush with the opening end of the opening 4. In this way, the strip connecting piece 8 can be attracted and fixed by the magnetic blocks 2, so that the light-shielding plate 7 will be fixed at the opening of the receiving groove 15 and will not fall off during the sample testing process.

[0034] It should be further noted that a battery 23 is installed inside the cavity 21. The battery 23 is connected to the control motherboard 18 through wires. The battery 23 can supply power to the control motherboard 18, thereby enabling the negative pressure pump 16, the electric control valve 22, the laser probe 17 and the detection probe 12 to work normally.

[0035] Operating Procedure: During testing, the operator installs the suction pipe 9 onto the pipe connector 20 and inserts the other end of the suction pipe 9 into the drinking water. Then, the control board 18 controls the negative pressure pump 16 to operate. The negative pressure pump 16 draws air out of the sample tube 11 through the adsorption tube 14 and the diversion tube 5, creating a negative pressure inside the sample tube 11. At this time, the suction pipe 9 generates suction, drawing drinking water into the sample tube 11. When the amount of drinking water in the sample tube 11 reaches a preset value, the operator shuts off the negative pressure pump 16 and the electronically controlled valve 2 via the control board 18. 2. Then, the operator rotates the light-shielding plate 7 to cover the opening of the receiving groove 15, so that the magnetic block 2 adsorbs and fixes the strip connecting piece 8, thereby fixing the light-shielding plate 7. Afterwards, the operator controls the laser probe 17 and the detection probe 12 to work through the control motherboard 18 to detect the residual chlorine and turbidity in the sample, and transmits the detection data to the control motherboard 18. Then, the control motherboard 18 can process the data and display it on the display screen on the outer shell 1. The operator can then complete the detection by watching it. The detection accuracy is high.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
