[0002] Water quality testing is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 11 As shown, the present invention provides a technical solution, a water quality detection device based on river ecological environmental protection restoration, comprising a base 1, a water reservoir is opened on the top of the base 1, a universal wheel 55 is arranged at the bottom of the base 1, a first support frame 2 is fixedly connected to the top of the base 1, a motor 3 is fixedly connected to the top of the first support frame 2, the output end of the motor 3 extends to the inside of the first support frame 2 and is fixedly connected to a screw rod 4, the outer wall of the screw rod 4 is connected to a first slider 5 through a screw nut pair, the first slider 5 is slidably connected to the first support frame 2, a second support frame 11 is fixedly connected to the top of the base 1 and away from the first support frame 2, a limiting shaft 12 is fixedly connected to the inner wall of the second support frame 11, a second slider 13 is slidably connected to the outer wall of the limiting shaft 12, the first slider 5 and the second slider 13 are rotatably connected to the side close to each other with a rotating shaft 14, a mounting plate 6 is fixedly connected between the two rotating shafts 14, a placing table 10 is slidably connected to the top of the mounting plate 6, and a clamping assembly is arranged on the top of the placing table 10.

[0039] Through the above technical solution, the test tube is fixed on the placement table 10 by the clamping assembly, and the test tube is moved by pushing the universal wheel 55. The motor 3 is started to drive the screw rod 4 to rotate, so that the first slider 5 moves upward or downward, thereby adjusting the height of the placement table 10 to facilitate the detection personnel to take and place the test tube. Through the provided water reservoir, clean water can be filled into the base 1 to clean the test tube after use.

[0040] Specifically, the outer walls of the two rotating shafts 14 are fixedly connected with the first gears 15 , the inner walls of the first support frame 2 and the second support frame 11 are fixedly connected with the first racks 16 , and the two first gears 15 are meshedly connected with the two first racks 16 , respectively.

[0041] Through the above technical solution, when the test tube is not in use, the motor 3 is started to drive the screw rod 4 to rotate, so that the first slider 5 moves downward, and the two rotating shafts 14 and the mounting plate 6 move downward. When the two rotating shafts 14 pass through the two first racks 16, the two first gears 15 respectively engage with the two first racks 16. As the first slider 5 continues to move downward, under the cooperation of the first gear 15 and the first rack 16, the two rotating shafts 14 are driven to rotate 180 degrees at the same time, so that the mounting plate 6 and the placement table 10 are flipped 180 degrees. After flipping, the test tube opening on the placement table 10 faces downward, which is convenient for preventing dust from falling into the test tube. When the test tube is in use, the first slider 5 is controlled to move upward. When the two rotating shafts 14 pass through the two first racks 16, the mounting plate 6 and the placement table 10 are flipped 180 degrees. After flipping, the test tube opening on the placement table 10 faces upward, which is convenient for detection personnel to use.

[0042] Specifically, a support plate 22 is fixedly connected between the first support frame 2 and the second support frame 11, and a plurality of water pumps 23 are fixedly connected to the bottom of the support plate 22 at equal intervals. The output end of the water pump 23 is connected to a first pipe 24, and the top of the first pipe 24 passes through the support plate 22 and is rotatably connected to a rotary joint 25, and the top of the rotary joint 25 is fixedly connected to a second pipe 26, and the bottom of the first pipe 24 extends to the inside of the water reservoir.

[0043] Through the above technical solution, after the test tube is used, the first slider 5 is controlled to move downward. When the two rotating shafts 14 pass through the two first racks 16, the test tube is flipped 180 degrees so that the test tube opening is downward, and the first slider 5 is continued to be controlled to move downward. When the test tube is close to the second pipe 26, the water pump 23 is started to pump the clean water in the water reservoir upward along the first pipe 24 and the second pipe 26. The clean water rushes upward to rinse the inside of the test tube. The clean water after rinsing naturally falls and is re-entered into the water reservoir. The clean water in the water reservoir needs to be replaced regularly.

[0044] Specifically, the outer wall of the second pipe 26 is fixedly connected to a fixing plate 27, the outer wall of the fixing plate 27 is provided with a sponge 29, a plurality of strip protrusions 30 are fixedly connected to the top of the sponge 29 and the outer wall at equal distances, an adjustment component is provided on the top of the support plate 22, and two groups of fixing rods 53 are symmetrically fixedly connected to the inner wall of the water reservoir, and the tops of the two groups of fixing rods 53 are fixedly connected to side panels 54.

[0045] Through the above technical solution, when the test tube is close to the second pipe 26, as the first slider 5 continues to move downward, the test tube is driven to continue downward, so that the sponge 29 is inserted into the test tube, and the screw rod 4 rotates while driving the second pipe 26 to rotate through the adjusting component, so that the sponge 29 and the plurality of strip-shaped protrusions 30 rotate to wipe the inner wall of the test tube, and cooperate with the test tube that continues to move downward, so that the sponge 29 and the plurality of strip-shaped protrusions 30 wipe different positions of the test tube. After cleaning the test tube, the first slider 5 is controlled to move upward to separate the test tube from the sponge 29. Since the test tube opening is downward at this time, it is convenient for the test tube to drain water, and prevents clean water from adhering to the test tube and affecting the accuracy of subsequent river water detection. As the first slider 5 moves upward, the sponge 29 is continuously controlled to rotate through the adjusting component, so that the clean water sucked into the sponge 29 is thrown out, thereby improving the effect of subsequent test tube cleaning. The thrown clean water splashes around, and after hitting the side plate 54, it is blocked by the side plate 54, and finally falls back into the reservoir along the side plate 54.

[0046] Specifically, a plurality of drainage grooves 28 are provided inside the fixed plate 27, the inner wall of the sponge 29 is set as an annular inclined surface, the inner wall of the second pipe 26 is slidably connected with the third pipe 34, the inner wall of the second pipe 26 is symmetrically fixedly connected with two second sliding shafts 31, the outer walls of the two second sliding shafts 31 are slidably connected with connecting blocks 32, the two connecting blocks 32 are fixedly connected to the third pipe 34, the outer walls of the two second sliding shafts 31 are sleeved with third springs 33, the top of the third spring 33 is fixedly connected to the connecting block 32, the bottom of the third spring 33 is fixedly connected to the second pipe 26, the top of the third pipe 34 is fixedly connected with a nozzle 35, the top and side of the nozzle 35 are provided with a water outlet 36, the inner wall of the nozzle 35 is fixedly connected with a diverter block 37, the bottom of the diverter block 37 is set as a symmetrical inclined surface, the top of the diverter block 37 is set as a symmetrical inclined surface, and the inner wall of the nozzle 35 and above the water outlet 36 is fixedly connected with a diverter plate 44.

[0047] Through the above technical solution, the water pump 23 is started to pump water, and the clean water flows along the first pipe 24, the second pipe 26, the third pipe 34, and the nozzle 35, and is sprayed out from the water outlet 36. When the clean water flows to the nozzle 35, it hits the symmetrical inclined surface at the bottom of the diverter block 37, thereby dividing the clean water into two streams and flowing upward along the symmetrical inclined surface at the top of the diverter block 37. When the clean water passes through the diverter plate 44, a part of it is intercepted by the diverter plate 44, so that the clean water is sprayed out from the water outlet 36 below. Through the cooperation of the diverter block 37, the circulation range of the clean water in the nozzle 35 is reduced, the water pressure is increased, the pressure of the sprayed clean water is greater, and the flushing effect on the test tube is better. In addition, the second pipe 26 is rotated to increase the spray range of the clean water, which is convenient for the test tube. Flushing at different positions, as the test tube continues to move downward, after the bottom of the test tube contacts the nozzle 35, the nozzle 35 and the third pipe 34 are moved downward under the push of the test tube to compress the third spring 33. After the nozzle 35 moves downward, as the test tube continues to move downward, the bottom of the test tube presses against the sponge 29. Under the squeezing of the test tube, the sponge 29 moves toward the center position, which has a better fit to the bottom of the test tube and improves the cleaning effect of the test tube. Under the continuous squeezing of the test tube, the water absorbed in the sponge 29 is squeezed out, and the squeezed water is discharged downward along the drain groove 28 and re-enters the water reservoir. At this time, the test tube is controlled to move upward and the water pump 23 is turned off. The sponge 29 that has squeezed out the water continues to rotate to facilitate absorbing the water attached to the inner wall of the test tube.

[0048] Specifically, the adjustment component includes a second rack 39, which is arranged at the top of the support plate 22 and is slidably connected to the support plate 22. The outer wall of the second pipe 26 is fixedly connected to the second gear 38, and the second gear 38 is meshed with the second rack 39. One end of the second rack 39 is fixedly connected to a connecting plate 40, and the connecting plate 40 is slidably connected to the support plate 22. The bottom of the screw rod 4 is fixedly connected to a U-shaped frame 41, and the bottom of the U-shaped frame 41 is fixedly connected to a rotating rod 42, which is rotatably connected to the first support frame 2, and the outer wall of the U-shaped frame 41 is rotatably connected to a connecting shaft 43, and the connecting shaft 43 is rotatably connected to the connecting plate 40.

[0049] Through the above technical solution, the screw rod 4 rotates and drives the U-shaped frame 41 to rotate. When the end of the U-shaped frame 41 rotates to the left, the connecting shaft 43 is pulled to move to the left, so that the connecting plate 40 moves to the left, and the second rack 39 is driven to move to the left, so that the second gear 38 rotates counterclockwise, and the second pipe 26 rotates counterclockwise. When the end of the U-shaped frame 41 rotates to the right, the connecting plate 40 is pushed to rotate to the right, and the second rack 39 is driven to move to the right, so that the second gear 38 rotates clockwise, and the second pipe 26 rotates clockwise. In this way, the second pipe 26 can be driven to rotate forward and reverse continuously while controlling the first slider 5 to move up and down.

[0050] Specifically, a straight groove 47 is opened on the inner wall of the mounting plate 6, and inclined grooves 46 are opened on the inner wall of the mounting plate 6 and at the top and bottom of the straight groove 47. The inner wall of the inclined groove 46 is set as a symmetrical inclined surface, and the outer wall of the second support frame 11 and the top of the support plate 22 are fixedly connected to the limiting rod 17, and the limiting rod 17 fits the inner wall of the straight groove 47.

[0051] When the first slider 5 moves downward, the limiting rod 17 below is inserted into the mounting plate 6, so that the mounting plate 6 can move downward stably.

[0052] Specifically, the inner wall of the mounting plate 6 is fixedly connected with the first sliding shaft 7, and the outer wall of the first sliding shaft 7 is slidably connected with the slide plate 8, and the slide plate 8 is fixedly connected to the placing table 10. The outer wall of the first sliding shaft 7 is sleeved with a first spring 9, one end of the first spring 9 is fixedly connected to the mounting plate 6, and the other end of the first spring 9 is fixedly connected to the slide plate 8. The placing table 10 is fixedly connected with a mounting frame 49 on the side close to the first supporting frame 2, and the inner wall of the mounting frame 49 is rotatably connected with a top plate 50. The top of the placing table 10 is fixedly connected with a baffle 51 used in conjunction with the top plate 50. A spring sheet 52 is arranged between the placing table 10 and the top plate 50. The elastic force of the first spring 9 is greater than the elastic force of the spring sheet 52. A plurality of top blocks 48 are equidistantly fixedly connected to the inner wall of the first supporting frame 2 and located below the first rack 16. The bottom of the top block 48 is provided with an inclined surface, and the top block 48 is used in conjunction with the top plate 50. A through groove 45 is opened inside the mounting plate 6, and the top block 48 fits the inner wall of the through groove 45.

[0053] Through the above technical solution, when the test tube opening is downward, the first slider 5 is continuously controlled to move downward, so that the mounting plate 6 moves downward. When passing through the top block 48, the straight surface of the top of the top block 48 presses against the top plate 50. As the first slider 5 continues to move downward, the top plate 50 rotates in the mounting frame 49 under the pressure of the top block 48, pressing the spring sheet 52. After the mounting plate 6 passes through the top block 48, the top plate 50 is reset under the action of the spring sheet 52. After the test tube is cleaned, the test tube is controlled to move upward. When it is close to the top block 48, the inclined surface at the bottom of the top block 48 presses against the top plate 50. Under the action of the baffle 51, the top plate 50 is pressed against the top plate 50. The top plate 50 is unable to rotate, and as the mounting plate 6 continues to move upward, the baffle plate 51 is pushed by the bottom inclined surface of the top block 48 to move laterally to the right, driving the placement table 10 to move laterally to the right, and the slide plate 8 to move laterally to the right, compressing the first spring 9. After the mounting plate 6 passes through the top block 48, the slide plate 8 is reset under the action of the first spring 9, driving the placement table 10 to reset and shake, and thus reciprocating. When the test tube is controlled to move upward after cleaning, the test tube is shaken multiple times by the set top blocks 48, which is convenient for quickly shaking off the clean water attached to the inner wall of the test tube.

[0054] Specifically, the clamping assembly includes a slot 18, which is arranged in a number and is equidistantly opened on the top of the placement table 10. The inner wall of the slot 18 is equidistantly slidably connected with four blocks 19. The tops of the four blocks 19 are all arranged as inclined surfaces. One side of the four blocks 19 is fixedly connected with a second spring 21. One end of the four second springs 21 is fixedly connected to the placement table 10. The outer wall of the block 19 is equidistantly provided with a number of anti-slip pads 20.

[0055] Through the above technical solution, when using a test tube to load a river water test sample, the test tube is inserted into the slot 18, and the bottom of the test tube is pressed against the inclined surfaces of the tops of the four blocks 19 at the same time. Under the squeezing of the test tube, the four blocks 19 are simultaneously moved toward the inside of the placement table 10 to compress the four second springs 21. After the test tube completely enters the slot 18, the four second springs 21 clamp the four blocks 19 around the test tube, and the anti-slip pad 20 is arranged to fit the outer wall of the test tube to prevent the test tube from slipping when the opening is downward.

[0056] A detection method based on a water quality detection device for river ecological and environmental restoration, the detection method is applicable to the above-mentioned water quality detection device for river ecological and environmental restoration, and the steps of the detection method are as follows:

[0057] S1: insert the test tube into the slot 18, fix the test tube on the placement table 10 through four clamps 19, and use the motor 3 to control the placement table 10 to move up and down, so that the test personnel can use it conveniently;

[0058] S2: When the test tube is not in use, the motor 3 is used to control the test tube to move downward. When passing through the two first racks 16, the two first gears 15 are respectively engaged with the two first racks 16, driving the mounting plate 6 and the placement table 10 to flip 180 degrees, so that the opening of the test tube faces downward to prevent dust;

[0059] S3: After using the test tube, the test tube is inserted into the sponge 29 to scrub the test tube. After cleaning the test tube, the test tube is controlled to move upward. Under the pressure of the top block 48, the test tube is shaken several times to shake out the cleaning water, and the test tube opening is kept downward to drain the water continuously.

[0060] When in use, when using a test tube to load a river water test sample, the test tube is inserted into the slot 18, and the bottom of the test tube is pressed against the inclined surfaces of the tops of the four blocks 19 at the same time. Under the squeezing of the test tube, the four blocks 19 are simultaneously moved toward the inside of the placement platform 10 to compress the four second springs 21. After the test tube completely enters the slot 18, the four blocks 19 are clamped and fixed around the test tube under the action of the four second springs 21. The test tube is conveniently moved by pushing the universal wheel 55, and the motor 3 is started to drive the screw rod 4 to rotate, so that the first slider 5 moves upward or downward, thereby adjusting the height of the placement platform 10, which is convenient for the test personnel to take and place the test tube. Through the provided water reservoir, clean water can be filled into the base 1 to clean the test tube after use. When the test tube is not in use, the motor 3 is started. The screw rod 4 is driven to rotate, so that the first slider 5 moves downward, and the two rotating shafts 14 and the mounting plate 6 move downward. When the two rotating shafts 14 pass through the two first racks 16, the two first gears 15 are respectively engaged with the two first racks 16. As the first slider 5 continues to move downward, under the cooperation of the first gear 15 and the first rack 16, the two rotating shafts 14 are driven to rotate 180 degrees at the same time, so that the mounting plate 6 and the placement table 10 are flipped 180 degrees. After flipping, the test tube opening on the placement table 10 faces downward to prevent dust from falling into the test tube. When the test tube is used, the first slider 5 is controlled to move upward. When the two rotating shafts 14 pass through the two first racks 16, the mounting plate 6 and the placement table 10 are flipped 180 degrees. After flipping, the test tube opening on the placement table 10 faces downward to prevent dust from falling into the test tube. When the first slider 5 moves downward, it drives the mounting plate 6 downward, so that the mounting plate 6 slides outside the upper limiting rod 17. The limiting rod 17 is set to ensure the stability of the movement of the mounting plate 6. When the mounting plate 6 moves to the position of being separated from the upper limiting rod 17, the first gear 15 is meshed with the first rack 16. Under the action of the first rack 16, the first gear 15 is rotated 180 degrees. As the first slider 5 continues to move downward, the limiting rod 17 below is inserted into the mounting plate 6, so that the mounting plate 6 keeps moving downward steadily. In order to prevent the mounting plate 6 from being slightly skewed after being turned over, an inclined groove 46 is opened inside the mounting plate 6. When the mounting plate 6 is slightly skewed, the limiting rod 17 presses against the inclined surface of the inclined groove 46. 7 is squeezed to help correct the angle of the mounting plate 6, and then the limiting rod 17 is smoothly inserted into the straight groove 47 to make the mounting plate 6 stable. Similarly, when the mounting plate 6 moves upward and flips, the inclined groove 46 can help correct the slightly skewed mounting plate 6. After using the test tube, the first slider 5 is controlled to move downward. When the two rotating shafts 14 pass through the two first racks 16, the test tube is flipped 180 degrees so that the test tube opening is downward. The first slider 5 is continued to be controlled to move downward to move the mounting plate 6 downward. When passing through the top block 48, the straight surface of the top of the top block 48 is pressed against the top plate 50. As the first slider 5 continues to move downward, under the squeezing of the top block 48, the top plate 50 is rotated in the mounting frame 49 to press the spring sheet 52. After the mounting plate 6 passes through the top block 48,Under the action of the spring sheet 52, the top plate 50 is reset. When the test tube is close to the second pipe 26, the water pump 23 is started to pump water, so that the clean water flows along the first pipe 24, the second pipe 26, the third pipe 34, and the nozzle 35, and is sprayed out from the water outlet 36. When the clean water flows to the nozzle 35, it hits the symmetrical inclined surface at the bottom of the diverter block 37, thereby dividing the clean water into two streams and flowing upward along the symmetrical inclined surface at the top of the diverter block 37. When the clean water passes through the diverter plate 44, a part of it is intercepted by the diverter plate 44, so that the clean water is sprayed out from the water outlet 36 below. Through the cooperation of the diverter block 37, the circulation range of the clean water in the nozzle 35 is reduced, the water pressure is increased, the pressure of the sprayed clean water is larger, the flushing effect on the test tube is better, and the clean water after flushing falls naturally and re When a new water reservoir is newly built, the clean water in the water reservoir needs to be replaced regularly. When the test tube is close to the second pipe 26, as the first slider 5 continues to move downward, the test tube is driven to continue to move downward, so that the sponge 29 is inserted into the test tube. While the screw rod 4 rotates, the U-shaped frame 41 is driven to rotate. When the end of the U-shaped frame 41 rotates to the left, the connecting shaft 43 is pulled to move to the left, so that the connecting plate 40 moves to the left, and the second rack 39 is driven to move to the left, so that the second gear 38 rotates counterclockwise, and the second pipe 26 rotates counterclockwise. When the end of the U-shaped frame 41 rotates to the right, the connecting plate 40 is pushed to rotate to the right, and the second rack 39 is driven to move to the right, so that the second gear 38 rotates clockwise, and the second pipe 26 rotates clockwise, thereby reciprocating. While the first slider 5 is controlled to move up and down, the second pipe 26 can be driven to continuously rotate forward and reversely. The rotation of the second pipe 26 drives the sponge 29 and the plurality of strip-shaped protrusions 30 to rotate to wipe the inner wall of the test tube. In conjunction with the test tube that continues to move downward, the sponge 29 and the plurality of strip-shaped protrusions 30 wipe different positions of the test tube, and in conjunction with the rotation of the second pipe 26, the spray range of the clean water is increased, which is convenient for flushing different positions of the test tube. As the test tube continues to move downward, after the bottom of the test tube contacts the nozzle 35, the nozzle 35 and the third pipe 34 are moved downward under the push of the test tube to compress the third spring 33. After the nozzle 35 moves downward, as the test tube continues to move downward, the bottom of the test tube presses against the sponge 29. Under the squeezing of the test tube, the sponge 29 moves toward the center. The center position moves, and the effect of fitting the bottom of the test tube is better, which improves the cleaning effect of the test tube. Under the continuous squeezing of the test tube, the water absorbed in the sponge 29 is squeezed out, and the squeezed water is discharged downward along the drainage groove 28 and re-enters the water reservoir. At this time, the test tube is controlled to move upward and the water pump 23 is turned off. The sponge 29 that has squeezed out the water continues to rotate, which is convenient for absorbing the water attached to the inner wall of the test tube. Since the test tube opening is downward at this time, it is convenient for the test tube to drain water, preventing clean water from adhering to the test tube and affecting the accuracy of subsequent river water detection. As the screw rod 4 controls the first slider 5 to move upward, the screw rod 4 continues to control the rotation of the sponge 29 while rotating, so as to facilitate the clean water absorbed in the sponge 29 to be thrown out, thereby improving the subsequent cleaning effect of the test tube. The thrown clean water splashes around.After hitting the side plate 54, it is blocked by the side plate 54 and finally falls back into the water reservoir along the side plate 54. After cleaning the test tube, the test tube is controlled to move upward. When it is close to the top block 48, the inclined surface at the bottom of the top block 48 presses against the top plate 50. Under the action of the baffle 51, the top plate 50 cannot rotate. As the mounting plate 6 continues to move upward, the baffle 51 moves horizontally to the right side under the push of the inclined surface at the bottom of the top block 48, driving the placement table 10 to move horizontally to the right side, and the slide plate 8 moves horizontally to the right side, pressing the first spring 9. After the mounting plate 6 passes through the top block 48, the slide plate 8 is reset under the action of the first spring 9, driving the placement table 10 to reset and shake, and thus reciprocating. When the test tube is controlled to move upward after cleaning, the test tube is shaken multiple times by the set top blocks 48, so that the clean water attached to the inner wall of the test tube can be quickly shaken off.
