Description

Technical Field

[0001] The present invention relates to the technical field of water quality detectors, in particular to an automatic water quality and water sample detector. Background Art

[0002] Modern water quality monitoring technology is the technical support for water resource environmental protection and governance. Multi-parameter water quality detectors based on modern water quality monitoring technology are an important development direction of water quality detection instruments today. Such instruments are developing in the direction of multi-parameter, online, remote, and networked monitoring. At the same time, the instruments have the characteristics of miniaturization, multi-function, and integration. At present, domestic and foreign water quality detection technologies can basically realize the detection of multiple elements in water.

[0003] In the prior art, when a water quality detector is working, electrode detection is a relatively common detection method in water quality detection. During use, when the liquid enters the detection device through the sampling port, due to the impact force of the water, the bubbles carried in the liquid will be partially adsorbed on the electrode surface during the rising process. Since the electrode potential in the solution is generated by the electron transfer between the electrode surface and the ions in the solution, if it is covered by irregular bubbles, the probability of electron transfer will change. The bubbles here are not conductive, so even extremely small bubbles will affect the detection results, thereby causing the measured value to be larger or smaller than the actual value.

[0004] Therefore, an automatic water quality and water sample detector is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic water quality and water sample detector to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: an automatic water quality and water sample detector, comprising:

[0007] A housing, wherein a control member is provided at the upper end of the housing and a detection cavity is opened at the lower end of the interior of the housing;

[0008] A fixing member is provided at the middle position of the lower end of the shell;

[0009] A detection electrode is installed through the outer surface of the upper end of the shell near the middle position, and one end of the detection electrode extends into the interior of the detection cavity;

[0010] A water inlet and a water outlet, the water inlet and the water outlet being installed on both sides of the outer surface of the shell; and:

[0011] Bubble removal mechanism;

[0012] The debubble mechanism is fixedly installed at the lower end of the left outer surface of the shell, and one end thereof extends into the interior of the detection cavity. The debubble mechanism can remove bubbles generated on the outer surface of the detection electrode when the detection electrode is working.

[0013] In the prior art, when the water quality detector is working, since electrode detection is a relatively common detection method in water quality detection, during use, when the liquid enters the detection device through the sampling port, due to the impact force of the water, the bubbles carried in the liquid will be partially adsorbed on the electrode surface during the rising process. Since the electrode potential of the electrode in the solution is generated by the electron transfer between the electrode surface and the ions in the solution, if it is covered by irregular bubbles, the probability of electron transfer will change. The bubbles here are non-conductive, so even very small bubbles will affect the detection results, thereby causing the measured value to be larger or smaller than the actual value. The present invention sets a bubble removal mechanism, which can timely remove bubbles attached to the detection electrode when the detection unit is working and the detection electrode is working, to prevent the bubbles carried in the liquid from being partially adsorbed on the detection electrode surface during the rising process due to the impact force of the water when the liquid enters the detection cavity through the water inlet during use, thereby affecting the detection results and ensuring the accuracy of the detection data.

[0014] Preferably, the bubble removal mechanism includes a motor, a first rotating rod, a first rotating wheel, a second rotating wheel, a second rotating rod, a third rotating wheel, a rotating column, a movable plate, a mounting ring, a brush strip, a scraper and a solar panel. The motor is fixedly installed on the right side of the interior of the shell near the upper edge of the detection chamber, the output shaft of the motor is fixedly installed with the first rotating rod, the right end of the first rotating rod is fixedly connected to the first rotating wheel, the inner surface of the shell is rotatably connected to the second rotating rod near the lower end of the first rotating rod, the right end of the second rotating rod is fixedly connected to the second rotating wheel, and the first rotating wheel is meshed with the second rotating wheel The third rotating wheel is fixedly installed on the outer surface of the left end of the second rotating rod, a movable plate is provided on the outer surface of the detection electrode near the right position, and a uniformly distributed rotating column is fixedly installed on the outer surface of the left side of the movable plate near the middle position, wherein several rotating columns located at the lower end of the movable plate are meshed and connected with the third rotating wheel, a mounting ring is fixedly installed on the outer surface of the right side of the movable plate near the upper end, and a uniformly distributed brush strip is fixedly installed on the annular inner surface of the mounting ring, and a uniformly distributed scraper is fixedly installed on the upper outer surface of the mounting ring, and a solar panel is fixedly installed on the upper outer surface of the control member.

[0015] During operation, the present invention sets a bubble removal mechanism. When the water quality needs to be tested and the detection electrode is working, the motor is controlled by the control component. The output shaft of the motor drives the first rotating rod to rotate, and the first rotating rod drives the first rotating wheel to rotate. Since the first rotating wheel is meshed and connected with the second rotating wheel, the first rotating wheel drives the second rotating wheel to rotate, and the second rotating wheel drives the third rotating wheel to rotate through the second rotating rod. Since several rotating columns at the lower end of the movable plate are meshed and connected with the third rotating wheel, and since the motor is a forward and reverse motor, the motor rotates clockwise when the motor is forward rotation, and rotates counterclockwise when the motor is reverse rotation. According to the forward and reverse control circuit diagram and its principle analysis, to realize the forward and reverse rotation of the motor, just swap the wiring of any two phases of the three-phase power supply line connected to the motor to achieve the purpose of reversal. When the motor rotates clockwise, the motor drives the third rotating wheel to rotate through the second rotating rod. During the rotation of the third rotating wheel, the movable plate is driven downward by the rotating column. When the third rotating wheel contacts the rotating column provided at the upper end of the outer surface of the movable plate, the control component controls the motor to reverse. At this time, during the rotation of the third rotating wheel, the movable plate is driven upward by the rotating column, thereby controlling the forward and reverse rotation of the third rotating wheel through the control component, driving the movable plate to reciprocate to the left. During the reciprocating movement of the movable plate, the brush strip is driven to reciprocate on the outer surface of the detection motor through the mounting ring. The bubbles on the outer surface of the detection electrode are cleaned. When the scraper moves back and forth, the impurities attached to the outer surface of the detection electrode can be cleaned to ensure that the detection electrode will not be affected by the attached impurities during detection, and the working effect of the detection electrode is guaranteed. Through the solar panel, solar energy can be converted into electrical energy during operation to provide electrical energy for charging, so that when the detection unit is working and the detection electrode is working, the bubbles attached to the detection electrode can be removed in time to prevent the bubbles carried in the liquid from entering the detection cavity through the water inlet during use due to the impact force of the water. The bubbles will be partially adsorbed on the surface of the detection electrode during the rising process, which will affect the detection results. The normal operation of the detection electrode is guaranteed, the accuracy of the detection data is guaranteed, and the overall practicality is improved.

[0016] Preferably, the second rotating rod passes through the right inner surface of the shell and extends to the outside of the shell, and a rotating fan is fixedly installed on the right end of the second rotating rod extending to the outside of the shell.

[0017] During operation, the present invention sets a second rotating rod that passes through the right inner surface of the shell and extends to the outside of the shell. Since this type of detector will be placed in water, by setting a rotating fan, during the flow of water, under the action of the impact force of the water flow, it will drive the bubble removal mechanism to work and clean the outer surface of the detection electrode, thereby avoiding impurities adhering to the detection electrode when the detection electrode does not work for a long time. On the one hand, it will reduce the working effect of the detection electrode. On the other hand, when the detection electrode is working, it avoids the problem of impurities affecting the normal operation of the detection electrode, thereby improving the overall practicality.

[0018] Preferably, an auxiliary mechanism is provided on the inner surface of the water inlet near the right edge;

[0019] The auxiliary mechanism includes a first mounting groove, a spring, a metal block, an electromagnet, a water pump and a one-way valve. A first mounting groove is opened at the upper end of the shell near the water inlet, a spring is fixedly installed on the inner top surface of the first mounting groove near the middle position, a metal block is fixedly installed on the lower end of the spring, an electromagnet is fixedly installed on the lower end of the shell near the water inlet, a water pump is fixedly installed on the inner surface of the water outlet near the left edge position, and a one-way valve is fixedly installed on the inner surface of the water outlet near the right side of the water pump.

[0020] During operation, the present invention sets a first mounting slot. When the detector is placed in water, the electromagnet is energized, and the electromagnet has magnetic force, which generates attraction for the metal block. The attraction causes the metal block to move toward the electromagnet until the electromagnet and the metal block are attracted together, completely blocking the water inlet. This prevents water that does not need to be measured from entering the detector during the placement process, affecting the accuracy of the data of the detector on the water layer that needs to be measured. When the detector completes the measurement of the water layer that needs to be measured, the water inside the detection chamber is conveniently discharged by setting a water pump and a one-way valve, which facilitates the next automatic measurement of the detector and improves the overall practicality and versatility.

[0021] Preferably, an elastic layer is fixedly installed inside the shell near the upper end of the electromagnet.

[0022] During operation, the present invention fixes an elastic layer near the upper end of the electromagnet inside the shell to ensure tightness when the electromagnet is connected to the metal block, thereby improving overall practicality.

[0023] Preferably, a threaded tube is fixedly installed on the upper outer surface of the water inlet near the middle position, a mounting block is fixedly installed on the upper outer surface of the threaded tube, an electric telescopic rod is fixedly installed on the upper outer surface of the mounting block, and the upper end of the electric telescopic rod is fixedly connected to the control component.

[0024] During operation, the present invention sets a threaded tube. Since this type of detector is always placed in water to detect water quality at any time, and the position of being placed in the water is fixed, when the staff needs to detect or monitor different water layers, it is inconvenient for the operator to operate. By setting the threaded tube, when the operator needs to adjust the water inlet layer, the magnetic force between the first magnet and the second magnet is overcome by manpower, and the left outer surface of the shell is slid up and down according to the position to be adjusted. When it is adjusted to the required position, the sliding can be cancelled. Therefore, when the staff needs to detect or monitor different water layers, the operator can operate conveniently, thereby improving overall practicality.

[0025] Preferably, a scale is provided near the middle position of the left outer surface of the shell.

[0026] During operation, the present invention provides a scale near the middle position on the left outer surface of the shell, which further facilitates the operation of the operator when the staff needs to detect or monitor different water layers, thereby improving the overall practicality.

[0027] Preferably, a filter screen is fixedly installed on the inner surface of the threaded pipe near one end edge and on the inner surface of the water outlet near the right end edge.

[0028] During operation, the present invention fixes filter screens on the inner surface of the threaded pipe near one end edge and on the inner surface of the water outlet near the right end edge, thereby preventing impurities such as aquatic plants in the water from entering the detector when water enters from the threaded pipe and affecting the detector's water quality detection, thereby improving overall practicality.

[0029] Preferably, an ultraviolet lamp is fixedly mounted on the inner surface of the shell near the left edge of the inner top surface of the detection cavity, and a resistance wire is fixedly mounted on the inner surface of the shell near the middle position of the inner bottom surface of the detection cavity.

[0030] During operation, the present invention can disinfect the interior of the detection cavity and evaporate the residual water inside after draining the water inside the detection cavity by arranging an ultraviolet lamp and a resistance wire, thereby ensuring the accuracy of the detector's next detection result and improving the overall practicality.

[0031] Preferably, a floating plate is provided inside the shell near the middle position of the left outer surface of the detection cavity, and a third magnet is fixedly installed on the left outer surface of the floating plate. A second mounting groove is opened inside the shell near the left position of the detection cavity, and a slider is slidably connected to the inner surface of the second mounting groove, and a fourth magnet is fixedly installed on the right outer surface of the slider. A second switch contact is provided on the inner surface of the second mounting groove near the lower edge, and a first switch contact is fixedly installed on the left outer surface of the slider.

[0032] During operation, the present invention sets a floating plate. In the process of draining the water inside the detection chamber, as the water level inside the detection chamber drops, the floating plate drops. During the dropping process, the attraction between the third magnet and the fourth magnet causes the slider to slide downward on the inner surface of the second mounting groove. When the water is drained, the floating plate drops to the bottom of the detection chamber, and the slider slides to the bottom of the second mounting groove. The first switch contact piece contacts the second switch contact piece, automatically turning on the ultraviolet lamp and the resistance wire, further improving the overall practicality and versatility.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The present invention is provided with a bubble removal mechanism, which can promptly remove bubbles attached to the detection electrode when the detection unit is working and the detection electrode 4 is working, thereby preventing the bubbles carried in the liquid from being partially adsorbed on the surface of the detection electrode during the rising process due to the impact force of the water when the liquid enters the detection cavity through the water inlet during use, thereby affecting the detection results and ensuring the accuracy of the detection data.

[0048] See also Figures 1 to 7 The present invention provides a technical solution for an automatic water sample detector:

[0049] A water quality and water sample automatic detection instrument, such as Figures 1 to 5 Shown, including:

[0050] A housing 1, wherein a control member 2 is provided at the upper end of the housing 1 and a detection chamber 6 is provided at the lower end of the interior of the housing 1;

[0051] A fixing member 3 is provided at the middle position of the lower end of the housing 1;

[0052] A detection electrode 4 is installed through the outer surface of the upper end of the housing 1 near the middle position, and one end of the detection electrode extends into the interior of the detection cavity 6;

[0053] A water inlet 8 and a water outlet 9, the water inlet 8 and the water outlet 9 being installed on both sides of the outer surface of the housing 1; and:

[0054] Bubble removal mechanism 5;

[0055] The debubble mechanism 5 is fixedly installed at the lower end of the left outer surface of the shell 1, and one end thereof extends into the interior of the detection cavity 6. The debubble mechanism 5 can remove bubbles generated on the outer surface of the detection electrode 4 when the detection electrode 4 is working.

[0056] In the prior art, when the water quality detector is working, electrode detection is a relatively common detection method in water quality detection. During use, when the liquid enters the detection device through the sampling port, due to the impact force of the water, the bubbles carried in the liquid will be partially adsorbed on the electrode surface during the rising process. Since the electrode potential in the solution is generated by the electron transfer between the electrode surface and the ions in the solution, if it is covered by irregular bubbles, the probability of electron transfer will change. The bubbles here are non-conductive, so even very small bubbles will affect the detection results, thereby causing the measured value to be larger or smaller than the actual value. The present invention sets a bubble removal mechanism 5, which can timely remove bubbles attached to the detection electrode 4 when the detection unit is working and the detection electrode 4 is working, to prevent the bubbles carried in the liquid from being partially adsorbed on the detection electrode 4 surface during the rising process due to the impact force of the water when the liquid enters the detection cavity 6 through the water inlet 8 during use, thereby affecting the detection results and ensuring the accuracy of the detection data.

[0057] As an embodiment of the present invention, Figures 1 to 5 As shown, the bubble removal mechanism 5 includes a motor 51, a first rotating rod 52, a first rotating wheel 53, a second rotating wheel 54, a second rotating rod 55, a third rotating wheel 56, a rotating column 57, a movable plate 58, a mounting ring 59, a brush strip 50, a scraper 510 and a solar panel 521. The motor 51 is fixedly installed on the right side of the interior of the shell 1 near the upper edge of the detection chamber 6, and the output shaft of the motor 51 is fixedly installed with the first rotating rod 52. The right end of the first rotating rod 52 is fixedly connected to the first rotating wheel 53. The inner surface of the shell 1 is rotatably connected to the second rotating rod 55 near the lower end of the first rotating rod 52. The right end of the second rotating rod 55 is fixedly connected to the second rotating wheel 54. The first rotating wheel 53 is connected to the The second rotating wheel 54 is meshed and connected, and the third rotating wheel 56 is fixedly installed on the outer surface of the left end of the second rotating rod 55. A movable plate 58 is provided on the outer surface of the detection electrode 4 near the right side, and a uniformly distributed rotating column 57 is fixedly installed on the left outer surface of the movable plate 58 near the middle position, wherein several rotating columns 57 located at the lower end of the movable plate 58 are meshed and connected with the third rotating wheel 56, and a mounting ring 59 is fixedly installed on the right outer surface of the movable plate 58 near the upper end, and a uniformly distributed brush strip 50 is fixedly installed on the annular inner surface of the mounting ring 59, and a uniformly distributed scraper 510 is fixedly installed on the upper outer surface of the mounting ring 59. The solar panel 521 is fixedly installed on the upper outer surface of the control component 2.

[0058] During operation, the present invention sets a bubble removal mechanism 5. When the water quality needs to be tested and the detection electrode 4 is working, the motor 51 is controlled by the control part 2. The output shaft of the motor 51 drives the first rotating rod 52 to rotate, and the first rotating rod 52 drives the first rotating wheel 53 to rotate. Since the first rotating wheel 53 is meshed and connected with the second rotating wheel 54, the first rotating wheel 53 drives the second rotating wheel 54 to rotate, and the second rotating wheel 54 drives the third rotating wheel 56 to rotate through the second rotating rod 55. Since the several rotating columns 57 at the lower end of the movable plate 58 are meshed and connected with the third rotating wheel 56, and since the motor 51 is a forward and reverse motor 51, the clockwise rotation of the motor 51 is the forward rotation of the motor 51, and the counterclockwise rotation of the motor 51 is the reverse rotation of the motor 51. According to the forward and reverse control circuit diagram and its principle analysis, to realize the forward and reverse rotation of the motor 51, any two phases of the three-phase power supply lines connected to the motor 51 can be connected in reverse order. When the motor 51 rotates clockwise, the motor 51 drives the third rotating wheel 56 to rotate through the second rotating rod 55. During the rotation of the third rotating wheel 56, the movable plate 58 is driven downward by the rotating column 57. When the third rotating wheel 56 contacts the rotating column 57 provided at the upper end of the outer surface of the movable plate 58, the control component 2 controls the motor 51 to reverse. At this time, during the rotation of the third rotating wheel 56, the movable plate 58 is driven upward by the rotating column 57, thereby controlling the forward and reverse rotation of the third rotating wheel 56 through the control component 2, driving the movable plate 58 to move back and forth to the left. During the reciprocating movement of the movable plate 58, since the mounting ring 59 is slidably sleeved on the outer side of the detection electrode 4, the mounting ring 59 drives the brush bar 50 to move back and forth on the outer surface of the detection motor 51 to clean the bubbles on the outer surface of the detection electrode 4. When the scraper 510 moves back and forth, it can clean the impurities attached to the outer surface of the detection electrode 4 to ensure that the detection electrode 4 will not be affected by the attached impurities during detection, and the working effect of the detection electrode 4 is guaranteed. Through the solar panel 521, solar energy can be converted into electrical energy during operation to provide electrical energy for charging, so that when the detection unit is working and the detection electrode 4 is working, the bubbles attached to the detection electrode 4 can be removed in time to prevent the bubbles carried in the liquid from entering the detection cavity 6 through the water inlet 8 during use due to the impact force of the water. The bubbles will be partially adsorbed on the surface of the detection electrode 4 during the rising process, which will affect the detection results. The normal operation of the detection electrode 4 is guaranteed, the accuracy of the detection data is guaranteed, and the overall practicality is improved.

[0059] As an embodiment of the present invention, Figure 2 As shown, the second rotating rod 55 passes through the right inner surface of the shell 1 and extends to the outside of the shell 1 . The right end of the second rotating rod 55 extending to the outside of the shell 1 is fixedly mounted with a rotating fan 511 .

[0060] During operation, the present invention sets a second rotating rod 55 that passes through the right inner surface of the shell 1 and extends to the outside of the shell 1. Since this type of detector will be placed in water, by setting a rotating fan 511, during the flow of water, under the action of the impact force of the water flow, it will drive the bubble removal mechanism 5 to work and clean the outer surface of the detection electrode 4, thereby avoiding impurities adhering to the detection electrode 4 when the detection electrode 4 does not work for a long time. On the one hand, it will reduce the working effect of the detection electrode 4. On the other hand, when the detection electrode 4 is working, it will avoid the problem of impurities affecting the normal operation of the detection electrode 4, thereby improving the overall practicality.

[0061] As an embodiment of the present invention, Figure 2 and Figures 6 and 7 As shown, an auxiliary mechanism 7 is provided on the inner surface of the water inlet 8 near the right edge;

[0062] The auxiliary mechanism 7 includes a first mounting groove 71, a spring 72, a metal block 73, an electromagnet 74, a water pump 75 and a one-way valve 76. A first mounting groove 71 is opened at the upper end of the shell 1 near the water inlet 8. A spring 72 is fixedly installed on the inner top surface of the first mounting groove 71 near the middle position, and a metal block 73 is fixedly installed on the lower end of the spring 72. An electromagnet 74 is fixedly installed on the lower end of the shell 1 near the water inlet 8. A water pump 75 is fixedly installed on the inner surface of the water outlet 9 near the left edge position, and a one-way valve 76 is fixedly installed on the inner surface of the water outlet 9 near the right side of the water pump 75.

[0063] During operation, the present invention sets a first mounting groove 71. When the detector is placed in water, due to the use of a ferromagnetic metal block 73, by energizing the electromagnet 74, the electromagnet 74 has magnetic force when energized, which generates an attraction for the metal block 73. The attraction causes the metal block 73 to move toward the electromagnet 74 until the electromagnet 74 and the metal block 73 are attracted together, completely blocking the water inlet 8, thereby preventing water that does not need to be measured from entering the detector during the placement process, affecting the accuracy of the data of the detector for the water layer that needs to be measured. When the detector completes the measurement of the water layer that needs to be measured, the water pump 75 and the one-way valve 76 are set to facilitate the discharge of water inside the detection chamber 6, thereby facilitating the next automatic measurement of the detector and improving the overall practicality and versatility.

[0064] As an embodiment of the present invention, Figure 7 As shown, an elastic layer 77 is fixedly installed inside the housing 1 near the upper end of the electromagnet 74.

[0065] During operation, the present invention fixes an elastic layer 77 near the upper end of the electromagnet 74 inside the housing 1 to ensure tightness when the electromagnet 74 is connected to the metal block 73, thereby improving overall practicality.

[0066] As an embodiment of the present invention, Figure 8 As shown, a threaded tube 78 is fixedly installed on the upper outer surface of the water inlet 8 near the middle position, a mounting block 79 is fixedly installed on the upper outer surface of the threaded tube 78, an electric telescopic rod 710 is fixedly installed on the upper outer surface of the mounting block 79, and the upper end of the electric telescopic rod 710 is fixedly connected to the control component 2.

[0067] During operation, the present invention sets a threaded tube 78. Since this type of detector is always placed in water to detect water quality at any time, and the position of the detector in the water is fixed, it is inconvenient for the operator to operate when the staff needs to detect or monitor different water layers. By setting an electric telescopic rod 710, when the operator needs to adjust the water inlet layer, the electric telescopic rod 710 is controlled by the control component 2 to move up and down, and the mounting block 79 is driven to slide up and down on the left outer surface of the shell 1 according to the position to be adjusted. The sliding can be cancelled when it is adjusted to the required position. Therefore, when the staff needs to detect or monitor different water layers, the operator can operate conveniently, thereby improving the overall practicality.

[0068] As an embodiment of the present invention, Figure 9 As shown, a scale 713 is provided near the middle position of the left outer surface of the housing 1 .

[0069] During operation, the present invention provides a scale 713 near the middle position on the left outer surface of the shell 1. When the staff needs to detect or monitor different water layers, it is convenient for the staff to calibrate and adjust the initial position of the mounting block 79, further facilitating the operation of the operator and improving the overall practicality.

[0070] As an embodiment of the present invention, Figure 2 As shown, a filter screen 712 is fixedly installed on the inner surface of the threaded tube 78 near one end edge and the inner surface of the water outlet 9 near the right end edge.

[0071] During operation, the present invention fixes a filter screen 712 on the inner surface of the threaded tube 78 near one end edge and on the inner surface of the water outlet 9 near the right end edge, so as to prevent impurities such as aquatic plants in the water from entering the detector when water enters from the threaded tube 78 and affecting the detector's water quality detection, thereby improving the overall practicality.

[0072] As an embodiment of the present invention, Figure 2 As shown, an ultraviolet lamp 513 is fixedly installed on the inner surface of the shell 1 near the left edge of the inner top surface of the detection cavity 6, and a resistance wire 512 is fixedly installed on the inner surface of the shell 1 near the middle position of the inner bottom surface of the detection cavity 6.

[0073] During operation, the present invention can disinfect the inside of the detection cavity 6 and evaporate the residual water inside after draining the water inside the detection cavity 6 by setting the ultraviolet lamp 513 and the resistance wire 512, thereby ensuring the accuracy of the detector's next detection result and improving the overall practicality.

[0074] As an embodiment of the present invention, Figure 2 and Figure 7 As shown, a floating plate 514 is provided at the middle position of the left outer surface of the detection chamber 6 inside the shell 1, and a third magnet 515 is fixedly installed on the left outer surface of the floating plate 514. A second mounting groove 516 is provided inside the shell 1 near the left side of the detection chamber 6, and a slider 517 is slidably connected to the inner surface of the second mounting groove 516. A fourth magnet 518 is fixedly installed on the right outer surface of the slider 517. A second switch contact 519 is provided on the inner surface of the second mounting groove 516 near the lower end edge, and a first switch contact 520 is fixedly installed on the left outer surface of the slider 517.

[0075] During operation, the present invention sets a floating plate 514. In the process of draining the water inside the detection chamber 6, as the water level inside the detection chamber 6 drops, the floating plate 514 drops. During the dropping process, the attraction between the third magnet 515 and the fourth magnet 518 causes the slider 517 to slide downward on the inner surface of the second mounting groove 516. When the water is drained, the floating plate 514 drops to the bottom of the detection chamber 6, and the slider 517 slides to the bottom of the second mounting groove 516. The first switch contact 520 contacts the second switch contact 519, automatically turning on the ultraviolet lamp 513 and the resistance wire 512, further improving the overall practicality and versatility.

[0076] Working principle: The present invention is provided with a bubble removal mechanism 5. When the water quality needs to be tested and the detection electrode 4 is working, the motor 51 is controlled by the control part 2. The output shaft of the motor 51 drives the first rotating rod 52 to rotate, and the first rotating rod 52 drives the first rotating wheel 53 to rotate. Since the first rotating wheel 53 is meshed and connected with the second rotating wheel 54, the first rotating wheel 53 drives the second rotating wheel 54 to rotate, and the second rotating wheel 54 drives the third rotating wheel 56 to rotate through the second rotating rod 55. Since the several rotating columns 57 at the lower end of the movable plate 58 are meshed and connected with the third rotating wheel 56, and since the motor 51 is a forward and reverse motor 51, the clockwise rotation of the motor 51 is the forward rotation of the motor 51, and the counterclockwise rotation of the motor 51 is the reverse rotation of the motor 51. According to the forward and reverse control circuit diagram and its principle analysis, to realize the forward and reverse rotation of the motor 51, any two phases of the three-phase power supply lines connected to the motor 51 can be connected in reverse order. When the motor 51 rotates clockwise, the motor 51 drives the third rotating wheel 56 to rotate through the second rotating rod 55. During the rotation of the third rotating wheel 56, the movable plate 58 is driven downward by the rotating column 57. When the third rotating wheel 56 contacts the rotating column 57 provided at the upper end of the outer surface of the movable plate 58, the control component 2 controls the motor 51 to reverse. At this time, during the rotation of the third rotating wheel 56, the movable plate 58 is driven upward by the rotating column 57, thereby controlling the forward and reverse rotation of the third rotating wheel 56 through the control component 2, driving the movable plate 58 to move back and forth to the left. During the reciprocating movement of the movable plate 58, since the mounting ring 59 is slidably sleeved on the outer side of the detection electrode 4, the mounting ring 59 drives the brush bar 50 to move back and forth on the outer surface of the detection motor 51 to clean the bubbles on the outer surface of the detection electrode 4. When the scraper 510 moves back and forth, it can clean the impurities attached to the outer surface of the detection electrode 4 to ensure that the detection electrode 4 will not be affected by the attached impurities during detection, and the working effect of the detection electrode 4 is guaranteed. Through the solar panel 521, solar energy can be converted into electrical energy during operation to provide electrical energy for charging, so that when the detection unit is working and the detection electrode 4 is working, the bubbles attached to the detection electrode 4 can be removed in time to prevent the bubbles carried in the liquid from entering the detection cavity 6 through the water inlet 8 during use due to the impact force of the water. The bubbles will be partially adsorbed on the surface of the detection electrode 4 during the rising process, which will affect the detection results. The normal operation of the detection electrode 4 is guaranteed, the accuracy of the detection data is guaranteed, and the overall practicality is improved.
