Description

Technical Field

[0001] The present invention relates to the field of urea solution detection, and more particularly, to a urea solution concentration detection device. Background Art

[0002] There are various types of urea solution detection devices for different detection purposes and scenarios. The following is an overview of urea solution detection devices: Urea solution detection devices mainly include various types such as portable, handheld, and desktop. These devices are widely used in the concentration detection of vehicle urea solution, the detection of urea in environmental sewage, and the detection of trace metals in urea solution, etc.

[0003] For example, the "Vehicle Urea Solution Concentration Detection Equipment" disclosed in the Chinese patent with the application number CN202311837014.4 has the following description in its specification: It includes a main body, an installation and connection mechanism, a cleaning mechanism, and a cleaning brush mechanism. One end of the main body is provided with an intelligent control panel. The bottom end of the sample tank is symmetrically and slidably connected with guide columns. The top ends of the fixed seats are fixedly connected with detection tanks, and detectors are arranged inside the detection tanks. A drain pipe is arranged at the bottom of the main body. This device can automatically detect vehicle urea, and at the same time, it can also automatically carry out overall cleaning, scrubbing, and rinsing work, eliminating the need for users to perform manual detection and cleaning work, thus providing great convenience for users. At the same time, through multiple cleaning, scrubbing, and rinsing, the cleanliness inside the device is ensured, and there is no need to worry about residual vehicle urea, thereby improving the accuracy of detection results.

[0004] Due to differences in production manufacturers and the influence of counterfeit and shoddy products, there are certain differences in the concentration and impurities of existing urea solutions. When urea needs to be added and used, to ensure that the urea used is a standard and high-quality urea solution, it is necessary to detect its concentration and content before use. Therefore, when selecting different brands of urea in the market, it is usually necessary to conduct multiple groups of comparisons and then make an optimal choice. Existing urea detection devices usually can only detect multiple brands of urea one by one in turn, and the detection process is relatively cumbersome. They cannot quickly and efficiently detect multiple groups of urea solutions simultaneously, resulting in poor use effects.

[0005] Therefore, we make improvements in this regard and propose a urea solution concentration detection device. Summary of the Invention

[0034] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] A urea solution concentration detection device provided by the present invention is to solve the problem that in the prior art, existing urea detection devices usually can only detect multiple brands of urea in a single-round and sequential manner, the detection process is relatively cumbersome, and they cannot quickly and efficiently detect multiple groups of urea solutions simultaneously, resulting in poor use effects. Through the multi-group detection chambers and detection tubes 9 provided in this application, different brands of urea solutions can be contained in multiple detection tubes 9, thereby facilitating the simultaneous extraction and detection of multiple groups of urea solutions of different brands;

[0036] In order to solve the problem in the prior art that the detection results are inaccurate due to the residual urea solutions of different brands on the vessels, through the high-pressure nozzle 22 and the cleaning frame 23 provided in this application, when the fixed frame 2 rotates to detect the urea solution in the next group of detection tubes 9, the cleaning liquid in the cleaning frame 23 is sprayed by the high-pressure nozzle 22 to clean the residual urea solution on the detection vessel 18, improving the accuracy of detecting different brands of urea.

[0037] Please refer to Figures 1-4, a urea solution concentration detection device, which includes a detector 1. A fixed 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 fixed frame 2. In order to facilitate the detection of multiple groups of urea solutions of different brands, multiple detection cavities are opened inside the rotating seat 3. Connecting frames 4 are arranged at the bottom ends of the inner sides of the detection cavities. A fixed column 5 is slidably connected to the end of the connecting frame 4. A first return spring 6 is arranged on the circumferential side of the fixed column 5. The bottom end of the first return spring 6 is fixedly connected to the connecting frame 4, and the top end of the first return spring 6 is fixedly connected to the fixed frame 2, which facilitates the reset of the connecting frame 4 when it is not in use through the elastic characteristic of the first return spring 6;

[0038] A detection component, which is arranged at the position inside the detection cavity. The connecting frame 4 is used in cooperation with the detection component;

[0039] A cleaning component, which is arranged at the position on one side of the fixed frame 2. The cleaning component is used in cooperation with multiple detection cavities.

[0040] During operation, through the structural cooperation design of the detection component and the cleaning component, and further through the multiple detection cavities and detection tubes 9 provided, it is realized that different brands of urea solutions are contained in multiple detection tubes 9, thereby facilitating the extraction and detection of multiple groups of urea solutions of different brands at the same time.

[0041] Please refer to Figures 2-4 , the detection component includes an introduction groove 7, a clamping groove 8, a detection tube 9, a clamping seat 10 and a clamping block 11. An introduction groove 7 is opened at the top end of the connecting frame 4. A clamping groove 8 is opened at the central position inside the connecting frame 4. A detection tube 9 is also arranged inside the detection cavity. In order to facilitate the clamping of the detection tube 9 and the connecting frame 4, a clamping seat 10 is fixedly connected to the bottom end of the detection tube 9. Multiple clamping blocks 11 are fixedly connected to the circumferential side of the clamping seat 10 and at positions corresponding to the introduction groove 7. The clamping blocks 11 are fitted with the introduction groove 7 and the clamping groove 8. During operation, when multiple groups of detection tubes 9 are respectively filled with different urea solutions of different brands, by sequentially placing them into the detection cavities, the clamping blocks 11 on the detection tube 9 are used to insert the clamping seat 10 into the position of the clamping groove 8 inside 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 blocks 11 and the clamping groove 8, improving its stability during subsequent detection.

[0042] The detection assembly further includes a sealing cover 12, a dripping seat 13 and a dripping groove 14. To prevent the urea liquid filled in the detection tube 9 from leaking during the detection process, the top end of the detection tube 9 is detachably connected with the sealing cover 12. To facilitate the discharge of the urea liquid in the detection tube 9 for detection, the center position at the bottom end of the clamping seat 10 is fixedly connected with the dripping seat 13. A dripping groove 14 is formed inside the dripping seat 13. The shape of the dripping groove 14 is a funnel shape with a larger upper part and a smaller lower part, to facilitate further position sealing of the urea liquid in the detection tube 9.

[0043] The detection assembly further includes a dripping rack 15, a second return spring 16, a sealing bead 17, a detection vessel 18 and an arc-shaped rack 19. The top end of the dripping groove 14 is fixedly connected with the dripping rack 15. The bottom end of the dripping rack 15 is fixedly connected with the second return spring 16. The bottom end of the second return spring 16 is fixedly connected with the sealing bead 17. Through the elastic characteristic of the second return spring 16, the force of pushing the sealing bead 17 downward is maintained, further reducing the gap between the sealing bead 17 and the dripping groove 14 to prevent the urea liquid in the detection tube 9 from dripping out when not in detection. At the top end of the detector 1 and at a position corresponding to the sealing bead 17, there is provided a detection vessel 18. To facilitate adjusting the position of the sealing bead 17 in the dripping groove 14, and thus facilitating dripping the liquid in the detection tube 9 downward onto the detection vessel 18 for detection, both sides of the sealing bead 17 are fixedly connected with the detector 1 by an arc-shaped rack 19, and the top end of the arc-shaped rack 19 is in contact with the sealing bead 17.

[0044] During operation, when the detection tube 9 to be detected rotates to the position of the detection vessel 18, the sealing bead 17 in the dripping seat 13 comes into contact and fits with the arc-shaped rack 19. When the sealing bead 17 contacts the highest point of the arc-shaped rack 19, the arc-shaped rack 19 pushes the sealing bead 17 towards the higher part of the dripping groove 14, thereby increasing the gap between the sealing bead 17 and the dripping groove 14. Then, the urea solution to be detected in the detection tube 9 drips downward through the gap between the dripping groove 14 and the sealing bead 17, further solving the problem in the prior art that the position of dripping the urea solution using a dropper is inaccurate and deviated, affecting the subsequent detection effect.

[0045] Please refer to Figures 4-7 To facilitate cleaning the residual urea solution on the detection vessel 18, the cleaning assembly includes a cleaning column 20, a cleaning pipe 21 and a high-pressure nozzle 22. At the top end of the detector 1 and at one end of the detection vessel 18, there is fixedly connected a cleaning column 20. The top end of the cleaning column 20 is fixedly connected with the cleaning pipe 21. A plurality of high-pressure nozzles 22 are fixedly connected to the circumferential side of the cleaning pipe 21. Through the re-pressurization of the high-pressure nozzles 22, the cleaning effect of the cleaning liquid for cleaning the detection vessel 18 is improved.

[0046] The cleaning assembly further includes a cleaning rack 23, a thin-skin cleaning bag 24, and a liquid guide tube 25. One side of the fixing rack 2 is fixedly connected to the cleaning rack 23. The inner side of the cleaning rack 23 is fixedly connected to the thin-skin cleaning bag 24. In order to facilitate the rapid introduction of the cleaning liquid in the cleaning rack 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. The end of the liquid guide tube 25 away from the cleaning rack 23 is fixedly connected to the cleaning column 20.

[0047] The cleaning assembly further includes an extrusion rack 26, a moving rack 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 rack 23 for use, an extrusion rack 26 is provided at one end of the inner side of the cleaning rack 23 close to the fixing rack 2. The center position of the bottom end of the extrusion rack 26 is fixedly connected to the moving rack 27. The center position of the moving rack 27 is threadedly connected to the extrusion screw 28. The end of the extrusion screw 28 close to the fixing rack 2 is fixedly connected to the first bevel gear 29. The end of the extrusion screw 28 away from the fixing rack 2 is rotatably connected to the cleaning rack 23. One end of the fixing rack 2 and the position corresponding to the moving rack 27 are fixedly connected to the linkage seat 30.

[0048] The cleaning assembly further includes a linkage column 31, a linkage gear 32, an arc-shaped rack 33, a retraction spring piece 34, and a second bevel gear 35. In order to clean the test 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 to the linkage column 31. The top end of the linkage column 31 is fixedly connected to the linkage gear 32. In order to clean the test vessel 18 while adjusting multiple groups of detection tubes 9, multiple groups of arc-shaped racks 33 are fixedly connected to the bottom end of the rotating seat 3 and the position corresponding to the linkage seat 30. In order to facilitate the extrusion of the cleaning rack 23 by the extrusion rack 26 through the rotation of the fixing rack 2 and the arc-shaped rack 33, the arc-shaped rack 33 is meshed with the linkage column 31. A retraction spring piece 34 is provided at the center position of the linkage gear 32. One end of the retraction spring piece 34 is fixedly connected to the linkage column 31, and the other end of the retraction spring piece 34 is fixedly connected to the linkage seat 30. The bottom end of the linkage column 31 is fixedly connected to the second bevel gear 35, and the second bevel gear 35 is meshed with the first bevel gear 29.

[0049] During operation, in order to facilitate the improvement of the detection speed of multiple groups of the device, when the previous urea detection is completed and the next group of urea detection is about to be carried out, when adjusting the position between the two groups of urea by rotating the fixing rack 2, at the same time, the arc-shaped rack 33 drives the extrusion rack 26 to extrude the cleaning rack 23, so that the cleaning liquid in it is efficiently sprayed on the test vessel 18 for cleaning, solving the problems of cumbersome detection and cleaning operation steps and poor detection efficiency in the prior art.

[0050] Please refer to Figure 1 and Figure 5, a liquid guide groove 36 is provided at the top end of the detector 1 and away from the high-pressure nozzle 22. During operation, the cleaning liquid is injected into the cleaning rack 23 through the liquid guide groove 36, which is convenient for maintaining an adequate amount of cleaning liquid in the cleaning rack 23 during use and improving the cleaning effect of the device.

[0051] Please refer to Figure 4 , a water inlet 37 is fixedly connected to the top end of the cleaning rack 23. During operation, when there is a large amount of water remaining on the test vessel 18 after cleaning, by tilting the device, the water on the test vessel 18 is discharged through the water inlet 37. After the water on the test vessel 18 has evaporated and dried, the next test is carried out. The design of the water inlet 37 improves the test effect of the test vessel 18.

[0052] Working process: After filling multiple groups of different urea solutions into the test tube 9, seal it with the sealing cover 12, and then sequentially insert the test tube 9 into the detection cavity. Use the clamping block 11 on the test tube 9 to insert the clamping seat 10 into the clamping groove 8 in the connecting frame 4 through the guiding groove 7. Then rotate the test tube 9 so that the test tube 9 is clamped to the connecting frame 4 through the clamping block 11 and the clamping groove 8. Then sequentially fix multiple groups of test tubes 9 in the rotating seat 3. Then start the detector 1. By pressing down the test tube 9 at the position corresponding to the detection vessel 18, the sealing bead 17 under the test tube 9 contacts the arc-shaped frame 19. Then the arc-shaped frame 19 pushes the sealing bead 17 upward, making the gap between the sealing bead 17 and the dripping groove 14 larger. Then the urea solution to be detected in the test tube 9 drips downward through the gap between the sealing bead 17 and the dripping groove 14 onto the detection vessel 18. Then detect it through the detection vessel 18. After the detector 1 starts to detect through the detection vessel 18, release the test tube 9, so that the sealing bead 17 moves downward through the elastic characteristic of the second return spring 16 to seal the test tube 9 and prevent the urea solution inside from continuing to drip. When the detection of the urea solution in the first test tube 9 is completed, rotate the fixing frame 2 in the direction close to the cleaning frame 23. Then, while rotating the fixing frame 2, drive the linkage gear 32 and then the linkage column 31 to rotate through the arc-shaped rack 33. Then the linkage column 31 drives the extrusion screw 28 and the first bevel gear 29 to rotate through the second bevel gear 35. Then drive the moving frame 27 and the extrusion frame 26 to squeeze the cleaning frame 23. Through extrusion, the cleaning liquid in the cleaning frame 23 is introduced into the cleaning tube 21 through the liquid guide tube 25. Then the cleaning liquid is sprayed out through the high-pressure nozzle 22 to clean the residual urea solution from the previous test on the detection vessel 18 to prevent it from affecting the next test. Then slightly tilt the device so that the cleaning liquid on the detection vessel 18 drains out of the device through the liquid guide groove 36. Continue to rotate the fixing frame 2. When the arc-shaped rack 33 no longer contacts the linkage gear 32, drive the linkage column 31 to reverse through the elastic characteristic of the retraction spring piece 34. Then drive the extrusion frame 26 to reset. After drying the cleaning liquid on the detection vessel 18, then press down the next test tube 9, which is convenient for detecting multiple groups of urea solutions of different brands.
