[0019] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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 creative work should fall within the scope of protection of the present invention.

[0020] The present invention provides a urea solution concentration detection device, in order to solve the problem that the existing urea detection devices in the prior art can usually only detect multiple brands of urea in turn at a time, the detection process is relatively cumbersome, and multiple groups of urea solutions cannot be detected simultaneously and quickly and efficiently, and the use effect is poor. The present application realizes that urea solutions of different brands are contained in multiple detection tubes 9 by setting multiple groups of detection chambers and detection tubes 9, thereby facilitating the extraction and detection of multiple groups of urea solutions of different brands at the same time; In order to solve the problem of inaccurate test results caused by different brands of urea solutions remaining on the vessels in the prior art, the present application provides a high-pressure nozzle 22 and a cleaning rack 23, so that when the rotating fixed rack 2 detects the urea solution in the lower group of detection tubes 9, the cleaning liquid in the cleaning rack 23 is sprayed out by the high-pressure nozzle 22 to clean the urea solution remaining on the detection vessel 18, thereby improving the accuracy of detecting different brands of urea.

[0021] Please refer to Figure 1-4A urea solution concentration detection device comprises a detector 1, a fixing frame 2 is fixedly connected to the top of the detector 1, a rotating seat 3 is rotatably connected to the inner side of the fixing frame 2, and multiple detection cavities are provided inside the rotating seat 3 to facilitate the detection of multiple groups of urea solutions of different brands, and a connecting frame 4 is provided at the bottom end of the inner side of the detection cavity, and a fixing column 5 is slidably connected to the end of the connecting frame 4, and a first reset spring 6 is provided on the ring side of the fixing column 5, and the bottom end of the first reset spring 6 is fixedly connected to the connecting frame 4, and the top end of the first reset spring 6 is fixedly connected to the fixing frame 2, so that the elastic characteristics of the first reset spring 6 can be used to reset the connecting frame 4 when it is not in use; A detection component is arranged at the inner side of the detection cavity, and a connecting frame 4 is used in conjunction with the detection component; The cleaning component is arranged at a position on one side of the fixing frame 2, and the cleaning component is used in conjunction with multiple groups of detection chambers.

[0022] During operation, through the structural coordination design of the detection component and the cleaning component, and further through the provision of multiple groups of detection cavities and detection tubes 9, it is possible to contain urea solutions of different brands through multiple detection tubes 9, thereby facilitating the extraction and detection of multiple groups of urea solutions of different brands at the same time.

[0023] Please refer to Figure 2-Figure 4 The detection assembly includes an introduction groove 7, a clamping groove 8, a detection tube 9, a clamping seat 10 and a clamping block 11. The top of the connecting frame 4 is provided with an introduction groove 7, and the center position of the inner side of the connecting frame 4 is provided with a clamping groove 8. The inner side of the detection cavity is also provided with a detection tube 9. In order to facilitate the clamping of the detection tube 9 with the connecting frame 4, the bottom end of the detection tube 9 is fixedly connected with a clamping seat 10, and a plurality of clamping blocks 11 are fixedly connected to the ring side of the clamping seat 10 and the position corresponding to the introduction groove 7. The clamping block 11 fits with the introduction groove 7 and the clamping groove 8. During operation, after multiple groups of detection tubes 9 are respectively loaded with different urea solutions of different brands, they are placed in the detection cavity in turn, and the clamping block 11 on the detection tube 9 is used to insert the clamping seat 10 into the position of the clamping groove 8 in the connecting frame 4 through the introduction groove 7, and then the detection tube 9 is rotated, so that the detection tube 9 is clamped with the connecting frame 4 through the clamping block 11 and the clamping groove 8, thereby improving its stability during subsequent detection.

[0024] The detection component also includes a sealing cover 12, a dripping seat 13 and a dripping groove 14. In order to prevent the urea liquid loaded in the detection tube 9 from leaking during the detection process, the top of the detection tube 9 is detachably connected with a sealing cover 12. In order to facilitate the discharge of the urea liquid in the detection tube 9 from the detection tube 9 for detection, the center position of the bottom of the clamping seat 10 is fixedly connected with the dripping seat 13. The inner side of the dripping seat 13 is provided with a dripping groove 14. The shape of the dripping groove 14 is a hole shape with a larger top and a smaller bottom, in order to facilitate further sealing of the urea liquid in the detection tube 9.

[0025] The detection assembly also includes a drip rack 15, a second return spring 16, a sealing bead 17, a detection vessel 18 and an arc frame 19. The top of the drip trough 14 is fixedly connected to the drip rack 15, the bottom end of the drip rack 15 is fixedly connected to the second return spring 16, and the bottom end of the second return spring 16 is fixedly connected to the sealing bead 17. Through the elastic characteristics of the second return spring 16, the force of pushing the sealing bead 17 downward is maintained, and the gap between the sealing bead 17 and the drip trough 14 is further reduced to prevent the urea liquid in the detection tube 9 from dripping when not being detected. A detection vessel 18 is provided at the top of the detector 1 and at a position corresponding to the sealing bead 17. In order to facilitate the adjustment of the position of the sealing bead 17 in the drip trough 14, and then facilitate the liquid in the detection tube 9 to drip downward onto the detection vessel 18 for detection, arc frames 19 are fixedly connected to the detector 1 on both sides, and the top of the arc frame 19 fits with the sealing bead 17.

[0026] During operation, after the detection tube 9 to be detected rotates to the position of the detection vessel 18, the sealing bead 17 in the drip seat 13 is in contact with the arc frame 19. When the sealing bead 17 contacts the highest point of the arc frame 19, the sealing bead 17 is pushed to the height of the drip groove 14 through the arc frame 19, thereby increasing the gap between the sealing bead 17 and the drip groove 14, and then the urea solution to be detected in the detection tube 9 drips downward through the gap between the drip groove 14 and the sealing bead 17, further solving the problem in the prior art that the position of dripping urea solution using a dropper is not accurate and the deviation affects the subsequent detection effect.

[0027] Please refer to Figure 4-Figure 7 In order to facilitate the cleaning of the urea solution remaining on the detection vessel 18, the cleaning component includes a cleaning column 20, a cleaning tube 21 and a high-pressure nozzle 22. The top of the detector 1 and one end of the detection vessel 18 is fixedly connected with the cleaning column 20, the top of the cleaning column 20 is fixedly connected with the cleaning tube 21, and the ring side of the cleaning tube 21 is fixedly connected with multiple high-pressure nozzles 22. The cleaning effect of the cleaning liquid for cleaning the detection vessel 18 is improved by re-pressurizing the high-pressure nozzle 22.

[0028] The cleaning assembly also includes a cleaning frame 23, a thin-skin cleaning bag 24 and a liquid guide tube 25. The cleaning frame 23 is fixedly connected to one side of the fixed frame 2, and the thin-skin cleaning bag 24 is fixedly connected to the inner side of the cleaning frame 23. In order to facilitate the rapid introduction of the cleaning liquid in the cleaning frame 23 into the cleaning tube 21 and the high-pressure nozzle 22, the bottom end of the thin-skin cleaning bag 24 is fixedly connected to the liquid guide tube 25, and the end of the liquid guide tube 25 away from the cleaning frame 23 is fixedly connected to the cleaning column 20.

[0029] The cleaning assembly also includes an extrusion frame 26, a movable frame 27, an extrusion screw 28, a first bevel gear 29 and a linkage seat 30. In order to facilitate the extrusion of the cleaning liquid in the cleaning frame 23 for use, an extrusion frame 26 is provided on the inner side of the cleaning frame 23 and close to one end of the fixed frame 2. The center position of the bottom end of the extrusion frame 26 is fixedly connected to the movable frame 27. The center position of the movable frame 27 is threadedly connected to the extrusion screw 28. The end of the extrusion screw 28 close to the fixed frame 2 is fixedly connected to the first bevel gear 29. The end of the extrusion screw 28 away from the fixed frame 2 is rotatably connected to the cleaning frame 23. A linkage seat 30 is fixedly connected to one end of the fixed frame 2 and at a position corresponding to the movable frame 27.

[0030] The cleaning assembly also includes a linkage column 31, a linkage gear 32, an arc-shaped rack 33, a retracting spring sheet 34, and a second bevel gear 35. In order to clean the detection vessel 18 while adjusting the detection position between the two groups of detection tubes 9, the inner side of the linkage seat 30 is rotatably connected with the linkage column 31, and the top of the linkage column 31 is fixedly connected with the linkage gear 32. In order to clean the detection vessel 18 while adjusting multiple groups of detection tubes 9, the bottom end of the rotating seat 3 and the position corresponding to the linkage seat 30 are fixedly connected with multiple groups of detection tubes 9. The arc-shaped rack 33 is meshed with the linkage column 31 to facilitate the extrusion frame 26 to extrude the cleaning frame 23 through the rotation of the fixed frame 2 and the arc-shaped rack 33. A retraction spring sheet 34 is provided at the center position of the linkage gear 32. One end of the retraction spring sheet 34 is fixedly connected to the linkage column 31, and the other end of the retraction spring sheet 34 is fixedly connected to the linkage seat 30. The bottom end of the linkage column 31 is fixedly connected with a second bevel gear 35, and the second bevel gear 35 is meshed with the first bevel gear 29.

[0031] During operation, in order to improve the detection speed of multiple groups of the device, after the detection of the previous group of urea is completed and the next group of urea is about to be detected, the position between the two groups of urea is adjusted by rotating the fixed frame 2, and at the same time, the arc-shaped rack 33 drives the extrusion frame 26 to squeeze the cleaning frame 23, so that the cleaning liquid in it is efficiently sprayed on the detection vessel 18 for cleaning, which solves the problem of cumbersome detection and cleaning operation steps and poor detection efficiency in the prior art.

[0032] Please refer to Figure 1 and Figure 5 A liquid guide groove 36 is provided at the top of the detector 1 and at one end away from the high-pressure nozzle 22. When working, cleaning liquid is injected into the cleaning frame 23 through the liquid guide groove 36, which is convenient for keeping the cleaning liquid in the cleaning frame 23 sufficient during use and improving the cleaning effect of the device.

[0033] Please refer to Figure 4The top of the cleaning rack 23 is fixedly connected with a water inlet 37. During operation, when a large amount of water remains on the detection vessel 18 due to cleaning, the device is tilted to drain the water on the detection vessel 18 through the water inlet 37. After the water on the detection vessel 18 evaporates, the next detection is performed. The detection effect of the detection vessel 18 is improved by the design of the water inlet 37.

[0034] Working process: After multiple groups of different urea solutions are loaded into the detection tube 9, the sealing cover 12 is used to seal it, and then the detection tube 9 is inserted into the detection cavity in turn, and the clamping block 11 on the detection tube 9 is used to insert the clamping seat 10 into the clamping groove 8 position in the connecting frame 4 through the introduction groove 7, and then the detection tube 9 is rotated so that the detection tube 9 is clamped with the connecting frame 4 through the clamping block 11 and the clamping groove 8, and then multiple groups of detection tubes 9 are fixed in the rotating seat 3 in turn, and then the detector 1 is started, and the detection tube 9 at the position corresponding to the detection vessel 18 is pressed downward to make the detection tube 9 The sealing bead 17 contacts the arc frame 19, and then the sealing bead 17 is lifted up by the arc frame 19, so that the gap between the sealing bead 17 and the dripping groove 14 becomes larger, and then the urea solution to be detected in the detection tube 9 drips downward onto the detection vessel 18 through the gap between the sealing bead 17 and the dripping groove 14, and then is detected by the detection vessel 18. When the detector 1 starts to detect through the detection vessel 18, the sealing bead 17 moves downward by the elastic characteristics of the second reset spring 16 by loosening the detection tube 9, and the detection tube 9 is sealed to prevent the urea solution therein from continuing to When the urea solution in the first detection tube 9 is detected, the rotating fixed frame 2 moves toward the direction close to the cleaning frame 23, and while the rotating fixed frame 2, the arc-shaped rack 33 drives the linkage gear 32 and then the linkage column 31 to rotate, and then the linkage column 31 drives the extrusion screw 28 and the first bevel gear 29 to rotate through the second bevel gear 35, and then drives the moving frame 27 and the extrusion frame 26 to squeeze the cleaning frame 23, and the cleaning liquid in the cleaning frame 23 is introduced into the cleaning tube 21 through the liquid guide tube 25 through the extrusion, and then the cleaning liquid is sprayed out through the high-pressure nozzle 22. The washing liquid cleans the urea solution of the last test remaining on the detection vessel 18 to prevent it from affecting the next test, and then the device is slightly tilted so that the washing liquid on the detection vessel 18 is discharged from the device through the liquid guide groove 36, and the fixed frame 2 continues to rotate. When the arc-shaped rack 33 and the linkage gear 32 are no longer in contact, the elastic characteristics of the retracting spring sheet 34 drive the linkage column 31 to reverse, and then drive the extrusion frame 26 to reset. After the washing liquid on the detection vessel 18 is wiped dry, the next detection tube 9 is pressed downward, so as to facilitate the detection of multiple groups of urea solutions of different brands.
