[0002] With the acceleration of industrialization and urbanization, water pollution problems are becoming increasingly serious. my country's environmental protection laws and regulations have put forward higher requirements for the real-time and accuracy of water quality monitoring, and promoted the development of water quality testing technology towards automation and intelligence. Water quality testing includes surface water monitoring, drinking water source monitoring, industrial wastewater discharge monitoring, etc. Water quality testing in the environmental monitoring process usually requires sampling personnel to conduct regional sampling of the tested waters, collect a variety of different samples, and then send the samples to the laboratory.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example Reference Figure 1-6 A water quality detection device for environmental monitoring includes a base 1, a functional cavity 2 is provided in the base 1, a column 3 is rotatably connected to the base 1 through a bearing, and a main control module 13 is provided in the functional cavity 2; The base 1 is provided with a detection mechanism, which is composed of a main detection component, a driving component, a pump component and a cleaning component; The main detection component includes a detection cavity 9 provided in the base 1, and a plurality of detection probes 10 are fixedly connected to the inner side wall of the detection cavity 9; The drive assembly includes a motor 7, which is fixedly connected to the bottom wall of the functional chamber 2. The top wall of the functional chamber 2 is rotatably connected to two reciprocating screws 17 through bearings. The two reciprocating screws 17 are both threadedly connected to a pump block 20. The pump liquid assembly includes a liquid tank 22, which is provided in the base 1, and a pump block 20 is sealingly and slidingly connected in the liquid tank 22; The cleaning assembly includes a cleaning chamber 27, which is provided in the base 1. Another pump block 20 is slidably connected to the base 1 and is sealed and slidably connected in the cleaning chamber 27. The side wall of the column 3 is fixedly connected to a plurality of sample tubes 4, and the bottom wall of the sample tube 4 is provided with a small hole (such as Figure 2 As shown), the sample tube 4 is connected to the detection chamber 9 through the small hole.

[0020] The main inspection component also includes a discharge pipe 11, which is fixedly connected to the base 1 and extends into the detection chamber 9. A solenoid valve 12 is provided in the discharge pipe 11. The detection probe 10 is connected to the main control module 13 through a wire. A second switch 35 is fixedly connected to the inner wall of the functional chamber 2. The second switch 35 is fixedly connected to the contact plate 36. After the second switch 35 is pressed, the detection can be started. After the detection is completed, the main control module 13 can also open the solenoid valve 12. After it is opened for a certain period of time, it will automatically close before the next sample injection (the control program of the solenoid valve 12 by the main control module 13 is existing technology and will not be repeated here).

[0021] The drive assembly further includes a first gear 8, which is an incomplete gear (e.g. Figure 3 As shown), during the rotation process, it will mesh with the second gear 15 and the third gear 21 in sequence. The first gear 8 is fixedly connected to the output shaft of the motor 7. The inner bottom wall of the functional chamber 2 is rotatably connected to two rotating shafts 14 through bearings. The rotating shaft 14 is fixedly connected to the second gear 15 and the first pulley 16. The first gear 8 meshes with the second gear 15. The reciprocating screw 17 is fixedly connected to the second pulley 18. The second pulley 18 and the corresponding first pulley 16 are jointly tensioned with a synchronous belt 19. The column 3 is fixedly connected to the third gear 21, and the first gear 8 meshes with the third gear 21.

[0022] The pump liquid assembly also includes a sleeve 24, which is fixedly connected to the side wall of the base 1 through a bracket. The sleeve 24 is sealed and slidably connected to a top column 25. The lower surface of the top column 25 is fixedly connected to a first switch 26. The first switch 26 is electrically connected to the main control module 13 through a wire. After the first switch 26 is pressed, the main control module 13 can start timing until the first switch 26 is released and the timing is stopped. By obtaining the time, since the speed of the motor 7 is constant, the sliding speed of the top column 25 is constant, and the diameter of the sample tube 4 is also constant, the amount of sample injected can be obtained by obtaining the sample injection time, that is, the main control module 13 can measure the amount of sample in the sample tube 4, and then obtain the test result based on the amount of sample injected, so that there is no need to quantitatively add samples as in existing detection equipment to obtain accurate test results, and it is more convenient to use. The sleeve 24 and the base 1 are jointly penetrated and fixedly connected with a hydraulic pipe 23. One end of the hydraulic pipe 23 extends through the sleeve 24, and the other end extends through the sleeve 24. The first gear 8 is driven by the second gear 15 on one side of the liquid tank 22, and the second gear 15 drives the first pulley 16 to rotate through the rotating shaft 14. The rotation of the first pulley 16 is driven by the second pulley 18 and the synchronous belt 19, so that the reciprocating screw 17 rotates. The rotation of the reciprocating screw 17 causes the corresponding pump block 20 to complete a cycle of up and down reciprocating motion. When the pump block 20 moves downward, the hydraulic oil drives the top column 25 to slide down. During the sliding process of the top column 25, it will contact the piston 5 and drive the piston 5 to slide downward, injecting the sample in the sample tube 4 into the detection chamber 9. Then the pump block 20 slides up and the hydraulic oil drives the top column 25 to reset, completing the automatic injection of the sample. There is no need for manual injection, which greatly reduces labor intensity and improves detection efficiency.

[0023] The cleaning component also includes an exhaust hole 30 and a drain hole 31. The exhaust hole 30 and the drain hole 31 both connect the cleaning chamber 27 with the detection chamber 9. A storage chamber 32 is provided in the base 1. The storage chamber 32 is filled with cleaning liquid (the cleaning liquid is distilled water). The base 1 is fixedly connected with a liquid inlet pipe 33. The liquid inlet pipe 33 connects the storage chamber 32 with the cleaning chamber 27. The base 1 is provided with an air inlet hole 28. The aperture of the air inlet hole 28 decreases from the outside to the inside of the cleaning chamber 27, so that the air can contact the heating wire 29 for a longer time. The air inlet hole 28 connects the cleaning chamber 27 with the outside world. A plurality of heating wires 29 are arranged in the air inlet hole 28. The heating wire 29 can heat the incoming air, thereby drying the detection chamber 9 with high-temperature air. After the detection is completed, the first gear 8 continues to rotate and meshes with the second gear 15 on one side of the cleaning chamber 27, so that the pump block 20 completes a cycle of up and down reciprocating motion, that is, cleaning The pump block 20 in the cavity 27 will complete a cycle of up and down reciprocating motion. When the pump block 20 moves downward, the cleaning liquid below the pump block 20 is pumped into the detection cavity 9 through the drainage hole 31 to flush the detection cavity 9, and the cleaning liquid is discharged through the discharge pipe 11. At the same time, the pump block 20 will also draw the external air through the air inlet hole 28 to the top of the pump block 20 when it slides down. During the suction process, the heating wire 29 heats the air, and when the pump block 20 moves upward, the pump block 20 pumps the heated air sucked in from above into the detection cavity 9 through the exhaust hole 30 to dry the interior and the cleaning liquid. At the same time, when the pump block 20 slides upward, the cleaning liquid stored in the storage cavity 32 is sucked into the bottom of the pump block 20 through the liquid inlet pipe 33, waiting for the next cleaning. After the detection is completed, cleaning and drying are automatically performed, which avoids the tediousness of manual cleaning and the possible omissions of manual cleaning, thereby ensuring accurate detection results.

[0024] A piston 5 is slidably connected to the sample tube 4, and an injection tube 6 is fixedly connected to the piston 5. A one-way valve is provided in the injection tube 6. The one-way valve in the injection tube 6 only allows liquid to pass from top to bottom and cannot flow in the opposite direction. A sealing rubber ring is fixedly connected to the side wall of the piston 5. The setting of the sealing rubber ring ensures the seal between the piston 5 and the sample tube 4 on the one hand, and on the other hand, there is a certain resistance to the sliding of the piston 5. It will slide downward only under the push of the top column 25, thereby preventing the internal sample from leaking.

[0025] One-way valves are provided in the exhaust hole 30, the drainage hole 31, the air inlet hole 28 and the liquid inlet pipe 33. The one-way valve in the exhaust hole 30 only allows air to enter the detection chamber 9 from the cleaning chamber 27, the one-way valve in the drainage hole 31 only allows cleaning liquid to enter the detection chamber 9 from the cleaning chamber 27, the one-way valve in the air inlet hole 28 only allows air to enter the cleaning chamber 27 from the outside, and the one-way valve in the liquid inlet pipe 33 only allows cleaning liquid to enter the cleaning chamber 27 from the storage chamber 32.

[0026] A replenishing hole 34 is provided in the base 1 , which connects the storage chamber 32 with the outside. Cleaning liquid can be replenished into the storage chamber 32 through the replenishing hole 34 .

[0027] A rubber pad is glued to the lower surface of the sample tube 4 . The provision of the rubber pad seals the gap between the sample tube 4 and the upper surface of the base 1 , thereby ensuring that the piston 5 slides downward to inject all the sample into the detection chamber 9 .

[0028] The present invention also provides a method for detecting water quality for environmental monitoring, comprising the following steps: S1. Sample collection: Take multiple samples from different areas of the water area to be tested and store them in different categories; S2. Sample injection: inject samples collected from different areas into different sample tubes 4 through a syringe, and record the sample injected into each sample tube 4; S3, detection: the pump assembly pumps the sample into the detection chamber 9, the main detection assembly detects the sample, and the main control module 13 records and feeds back the detection results; S4, cleaning: After the test is completed, the sample is discharged from the test cavity 9, and the cleaning component cleans the inside of the test cavity 9; S5, detection completed: repeat steps S3 and S4 multiple times to detect the samples in all sample tubes 4; S6. Data sorting: sorting and collecting the data recorded by the main control module 13.

[0029] In the present invention, after sampling, the sample is injected into different sample tubes 4 through a syringe and an injection tube 6, and the sample data in each sample tube 4 is recorded to facilitate classification and data organization.

[0030] After the sample injection is completed, the motor 7 is turned on, and the rotation of the motor 7 drives the first gear 8 to rotate. The first gear 8 first drives one of the second gears 15 to rotate, and the second gear 15 drives the first pulley 16 to rotate through the rotating shaft 14. The rotation of the first pulley 16 is driven by the second pulley 18 and the synchronous belt 19, so that the reciprocating screw 17 rotates. The rotation of the reciprocating screw 17 causes the corresponding pump block 20 to complete a cycle of up and down reciprocating motion. When the pump block 20 moves downward, the hydraulic oil is transmitted to make the top column 25 slide down. During the sliding process of the top column 25, it will contact the piston 5 and drive the piston 5 to slide downward, injecting the sample The sample in the tube 4 is injected into the detection chamber 9, and during the injection process, when the top column 25 slides down and contacts the piston 5, the first switch 26 will also be pressed. After the first switch 26 is pressed, the main control module 13 can start timing until the first switch 26 is released, and then stop timing. By obtaining this time, since the speed of the motor 7 is constant, the sliding speed of the top column 25 is constant, and the diameter of the sample tube 4 is also constant, the amount of sample injected can be obtained by obtaining the sample injection time, that is, the main control module 13 can measure the amount of sample in the sample tube 4, and then the pump block 20 slides up, and the top column 25 is reset through the transmission of hydraulic oil.

[0031] After the top column 25 is reset, the first gear 8 rotates and contacts the contact plate 36, thereby pressing the second switch 35. After the second switch 35 is pressed, the detection probe 10 detects the injected sample and transmits the detection data to the main control module 13. The main control module 13 calculates the detection result based on the amount of the injected sample and records the detection result.

[0032] After the detection is completed, the main control module 13 opens the solenoid valve 12 and the sample is discharged through the discharge pipe 11. At this time, the first gear 8 continues to rotate and meshes with the other second gear 15, so that the other pump block 20 completes a cycle of up and down reciprocating motion, that is, the pump block 20 in the cleaning chamber 27 will complete a cycle of up and down reciprocating motion. When the pump block 20 moves downward, the cleaning liquid below the pump block 20 is pumped into the detection chamber 9 through the drainage hole 31 to flush the detection chamber 9. The cleaning liquid is discharged through the discharge pipe 11. At the same time, the pump block 20 will also slide down and the external air will be sucked into the top of the pump block 20 through the air inlet 28. During the suction process, the heating wire 29 heats the air, and when the pump block 20 moves upward, the pump block 20 pumps the heated air sucked from above into the detection chamber 9 through the exhaust hole 30 to dry the interior and dry the cleaning liquid. At the same time, when the pump block 20 slides upward, the cleaning liquid stored in the storage chamber 32 is sucked into the bottom of the pump block 20 through the liquid inlet pipe 33, waiting for the next cleaning.

[0033] After cleaning and drying are completed, the first gear 8 continues to rotate until it engages with the third gear 21. At this time, the main control module 13 closes the solenoid valve 12, and the first gear 8 drives the third gear 21 to rotate, thereby rotating the column 3 and rotating the next sample tube 4 storing the sample to be tested to the top of the detection chamber 9. Then the first gear 8 continues to rotate and engages with the second gear 15 to inject the sample. This cycle repeats. After completing the detection of samples in all sample tubes 4, the machine is stopped and the data can be sorted.

[0034] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
