[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-5As shown, a vehicle urea solution concentration detection device includes a base plate 1; an articulated frame 2 is installed at the bottom of the base plate 1; a telescopic component 3 is hinged on the articulated frame 2; a sampling component 4 is rotatably connected to the bottom of the telescopic component 3; the driving component includes a sampling cylinder 41; a fine filter plate 43 is installed in the sampling cylinder 41; a driving shaft 42 is rotatably connected to the fine filter plate 43; a worm wheel blade 46 is installed on the driving shaft 42; a coarse filter screen 44 is installed at the bottom of the sampling cylinder 41; the fine filter plate 4 3 is arranged above the coarse filter 44; a cleaning scraper 45 is installed at the bottom of the driving shaft 42; the cleaning scraper 45 is arranged at the bottom of the fine filter plate 43; when working, the device is inserted into the solution cylinder or solution pool to be tested, and then the water pump 6 extracts the solution in the sampling cylinder 41 through the bellows 5. The extraction force creates a negative pressure in the sampling cylinder 41, which drives the solution to be extracted. The coarse filter plate installed in the solution filters large particles of impurities, and the fine filter plate 43 filters small particles of impurities. While extracting, the solution is extracted. The extraction force drives the worm wheel blade 46 to rotate, and then the worm wheel blade 46 drives the drive shaft 42 to rotate, and the drive shaft 42 drives the cleaning scraper 45 connected to the bottom to rotate, and then the cleaning scraper 45 rotates to scrape and clean the fine filter plate 43, reducing the clogging of the fine filter plate 43 and affecting the filtration; the fine filter plate 43 can effectively filter out small particles of impurities in the solution, ensuring that the sample entering the detection equipment is purer, which can reduce the interference of small particles on the detection instrument and improve the accuracy of concentration detection. At the same time, the combination of the coarse filter 44 and the fine filter plate 43 can more comprehensively filter out impurities of different sizes, further ensuring the purity of the sample; during long-term use, the filter plate is prone to clogging due to the accumulation of impurities, affecting the filtration effect and the normal operation of the equipment. The cleaning scraper 45 can, while extracting the solution, promptly clean out impurities attached to the filter plate by rotating and scraping the fine filter plate 43, reducing the occurrence of clogging. This not only keeps the filter plate unobstructed, but also extends the service life of the equipment.

[0025] Further, such as Figure 1 、 2As shown in Figure 4, the telescopic assembly 3 includes a rotating column 31; the rotating column 31 is hinged on the hinged frame 2; the bottom of the rotating column 31 is rotatably connected to a threaded sleeve 33; a fixed column 32 is installed on the threaded sleeve 33; the threaded sleeve 33 is internally threadedly connected to a screw 34; the bottom of the screw 34 is connected to the bottom of the sampling tube 41; when working, the fixed column 32 is rotated, and the fixed column 32 drives the threaded sleeve 33 to rotate on the rotating column 31, and then the threaded sleeve 33 drives the screw 34 threadedly connected thereto to extend and retract, thereby adjusting the overall detection length of the device, so that the device can flexibly adjust the overall detection length according to actual detection needs. This is particularly important for testing environments such as solution cylinders and solution pools of different depths or heights, which improves the adaptability and flexibility of the equipment; the hinged design between the rotating column 31 and the articulated frame 2 enables the equipment to adjust its angle on the horizontal plane. This design allows the user to easily change the detection angle according to the specific detection position or needs to achieve the best sampling and detection effect, which not only improves the accuracy of the detection, but also increases the convenience of operation of the equipment.

[0026] Further, such as Figure 1 、 2 As shown, a bellows 5 is installed on the top of the sampling tube 41; the top of the bellows 5 passes through one end of the base plate 1 and is connected to a water pump 6, and the water pump 6 is fixed on the top of the base plate 1; when working, the bellows 5 can be extended as the telescopic component 3 adjusts the overall height; the water pump 6 extracts the detection solution in the sampling tube 41 through the bellows 5.

[0027] Further, such as Figure 1 As shown, the water pump 6 is connected to a connecting pipe 7; the other end of the connecting pipe 7 is connected to a urea solution concentration detection instrument body 8; when working, the detection solution extracted by the water pump 6 is pumped into the urea solution concentration detection instrument body 8 through the connecting pipe 7 to detect the urea solution concentration.

[0028] Further, such as Figure 1 、 5 As shown, the base plate 1 is provided with a clamping groove 9 on both sides; a bolt 10 is clamped in the clamping groove 9; a hydraulic rod 11 is hinged at the bottom of the bolt 10; an anti-slip pad 13 is installed at the bottom of the hydraulic rod 11; a handle 12 is installed on the top of the base plate 1; when working, the bolt 10 is clamped in the clamping groove 9 and then the bolt 10 is tightened, so that the hydraulic rod 11 is fixed on the base plate 1, and the two hydraulic rods 11 can support the equipment. When the equipment needs to be supported, it can be installed and removed when not in use. The user can choose according to his own needs. The adjustability of the hydraulic rod 11 allows the user to adjust the height and level of the equipment according to the ground conditions, further enhancing the stability of the equipment; the handle 12 can be used to pick up the equipment for easy sampling.

[0029] Working principle: when working, the device is inserted into the solution cylinder or solution pool to be tested, and then the water pump 6 extracts the solution in the sampling cylinder 41 through the bellows 5. The extraction force generates negative pressure in the sampling cylinder 41, which drives the solution to be extracted. The coarse filter plate installed in the solution filters large particles of impurities, and the fine filter plate 43 filters small particles of impurities. While extracting, the extraction force generated by the solution extraction drives the worm wheel blade 46 to rotate, and then the worm wheel blade 46 drives the drive shaft 42 to rotate, and the drive shaft 42 drives the cleaning scraper 45 connected to it at the bottom to rotate, and then the cleaning scraper 45 rotates to scrape and clean the fine particles. The filter plate 43 is caused to clog, and the filtration is affected. The fine filter plate 43 can effectively filter out small particles of impurities in the solution, ensuring that the sample entering the detection equipment is purer, which can reduce the interference of small particles on the detection instrument and improve the accuracy of concentration detection. When working, the fixed column 32 is rotated, and the fixed column 32 drives the threaded sleeve 33 to rotate on the rotating column 31, and then the threaded sleeve 33 drives the screw 34 threadedly connected thereto to extend and retract, thereby adjusting the overall detection length of the device, so that the device can flexibly adjust the overall detection length according to actual detection needs. This is particularly important for testing environments such as solution cylinders and solution pools of different depths or heights, which improves the adaptability and flexibility of the equipment; when working, the bellows 5 can be extended as the telescopic component 3 adjusts the overall height; the water pump 6 extracts the test solution in the sampling cylinder 41 through the bellows 5; when working, the test solution extracted by the water pump 6 is pumped into the urea solution concentration detection instrument body 8 through the connecting pipe 7 to detect the urea solution concentration; when working, by clamping the bolt 10 in the clamping groove 9 and then tightening the bolt 10, the hydraulic rod 11 is fixed to the base plate 1, and the two hydraulic rods 11 can support the equipment. When the equipment needs to be supported, it can be installed and removed when not in use. The user can choose according to his own needs.
