[0027] Example 1

[0028] A mobile water pollution detection device, such as Figures 1 to 3 As shown, the hull includes a hull 1, with two propellers 2 at one end. Two drive motors for driving the propellers 2 are installed inside the hull 1. A winding wheel 4 is rotatably connected to the inner wall of the hull 1, and a winding motor for driving the winding wheel 4 is installed inside the hull 1. A sampling hose 5 is wound around the outer wall of the winding wheel 4. One end of the sampling hose 5 is connected to a sampling head 3, and the other end of the sampling hose 5 is connected to a water pump via a right-angle rotary joint. The right-angle rotary joint is a mature existing technology, and its basic structure and working principle are well known to those skilled in the art, so it will not be described in detail here. The outlet end of the water pump is connected to an outlet pipe 9. A central shaft 6 is fixedly connected to the inner wall of the hull 1, and a turntable 7 is rotatably fitted to the outer wall of the central shaft 6. Multiple circumferentially arranged placement slots are formed on the top outer wall of the turntable 7. A sample tube is placed in the hull. A drive motor 12 is installed inside the hull 1. The output shaft of the drive motor 12 is connected to the turntable 7 through a gear transmission assembly. The gear transmission assembly is a mature existing technology, and its basic structure and working principle are well known to those skilled in the art, so it will not be described in detail here. A sealing cover 8 is magnetically attached to the top of the central shaft 6. The sealing cover 8 is located above the turntable 7, and the bottom outer side of the sealing cover 8 is slidably sealed with the turntable 7. One end of the water outlet pipe 9 is connected to the sealing cover 8, and the water outlet pipe 9 is aligned with a sample tube. A water quality detector 10 is installed on the inner wall of the hull 1, located on one side of the turntable 7. A telescopic rod 11 is installed on the top outer wall of the hull 1. The probe of the water quality detector 10 is installed on the telescopic end of the telescopic rod 11, and the probe passes through the sealing cover 8 and is inserted into a sample tube.

[0029] The sampling head 3 includes a housing 13 and a filter screen 14. The housing 13 is fixedly connected to one end of the sampling hose 5. The filter screen 14 is embedded in the outer wall of the housing 13. The outer wall of the housing 13 is provided with a perforated plate 15, which is located on one side of the filter screen 14. The inner wall of the housing 13 is slidably fitted with a perforated plate 16. The inner wall of the housing 13 is fixed with a guide cylinder 17 by a fixing bracket. The inner wall of the guide cylinder 17 is slidably fitted with a connecting rod 18. The other end of the connecting rod 18 is connected to the perforated plate 16. A spring 19 is installed on the inner wall of the guide cylinder 17. The two ends of the spring 19 are respectively connected to the inner wall of the guide cylinder 17 and the connecting rod 18. Two electromagnets are installed opposite each other on the inner wall of the guide cylinder 17 and one end of the connecting rod 18.

[0030] During testing, the hull 1 is placed on the water surface. At this time, the holes of the perforated plate 16 and the perforated plate 15 are misaligned, preventing external water from entering the shell 13 through the perforated plates 15 and 16. The drive motor drives the propeller 2 to rotate, propelling the hull 1 forward. By controlling the rotation of the two drive motors, the hull 1 can move forward, backward, and turn. When the hull 1 moves to the testing point, the winding motor drives the winding wheel 4 to unwind the sampling hose 5. The sampling head 3 moves downward under gravity. When the sampling head 3 moves to the sampling depth, the electromagnet is energized, causing magnetic attraction between the electromagnets, pulling the connecting rod 18 upward. The spring 19 is compressed and deformed, aligning the holes on the perforated plate 16 and the perforated plate 15. External water enters the shell 13 through the filter screen 14, and the water pump passes through the sampling... The hose 5 draws in the sample and then injects it into a sample tube through the outlet pipe 9. The drive motor 12 drives the turntable 7 to rotate, moving the sample tube containing the sample to below the probe. The telescopic rod 11 drives the probe to insert into the sample tube, and the water quality analyzer 10 performs water quality testing. During the sampling process, the sealing cover 8 can seal the top of the sample tube to prevent sample water from splashing inside the hull 1 due to device shaking. If testing is required in other water areas, the device is moved to the next water area, and the above steps are repeated. After the test is completed, the user retrieves the device, drains the water from the sampling head 3 and the sampling hose 5, then de-energizes the electromagnet, and the spring 19 pushes the connecting rod 18 down. The perforated plate 2 16 and the perforated plate 15 are misaligned to seal the housing 13, and the sealing cover 8 is removed. The sample tube is taken out, cleaned, and then put back.

[0031] By setting up a sampling head 3, the shell 13 is sealed when the sampling head 3 has not reached the sampling depth, so as to prevent water at other depths from entering the shell 13 when the sampling head 3 moves and being sampled together, which would affect the test results.

[0032] By setting up a sealing cover 8, the top of the sample tube can be sealed to prevent sample water from splashing inside the hull 1 due to device shaking.

[0033] Example 2

[0034] A mobile water pollution detection device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 1 , Figure 4 As shown, floats 20 are fixedly connected to the outer walls of both sides of the hull 1 via connecting components 21. The connecting components 21 include connecting blocks 22 and connecting rods 23. The connecting blocks 22 are fixed to the side walls of the hull 1, and the connecting rods 23 are fixedly connected to one side of the top of the floats 20. The connecting rods 23 are U-shaped, and one end of the connecting rods 23 is inserted into the connecting blocks 22. The side walls of the connecting blocks 22 are rotatably connected to a limiting clamp 24. The rotating shaft of the limiting clamp 24 is connected to a torsion spring, and the inner wall of the connecting rods 23 is provided with a limiting groove that cooperates with the limiting clamp 24.

[0035] Before placing the device, press the limiting clamp 24. The torsion spring twists and deforms, moving the limiting clamp 24 away from the connecting plug 22. Then, insert the connecting rod 23 into the connecting plug 22. Release the limiting clamp 24. The torsion spring resets the limiting clamp 24, and the limiting clamp 24 is inserted into the limiting groove, completing the installation of the float 20. The float 20 can increase the contact area between the device and the water surface, making the device more stable.

[0036] By incorporating the float plate 20 and connecting assembly 21, the contact area between the device and the water surface can be increased, making the device more stable. The float plate 20 can also be removed during storage and transportation for easier handling.

[0037] Working principle: During testing, pressing the limiting clamp 24 causes the torsion spring to twist and deform, moving the limiting clamp 24 away from the connecting plug 22. Then, the connecting rod 23 is inserted into the connecting plug 22. Releasing the limiting clamp 24 causes the torsion spring to reset the limiting clamp 24, which then inserts into the limiting groove, completing the installation of the float 20. The float 20 can increase the contact area between the device and the water surface, making the device more stable. When the hull 1 is placed on the water surface, the holes of the perforated plate 26 and the perforated plate 15 are... The misalignment prevents external water from entering the hull 13 through the perforated plate 15 and perforated plate 16. The drive motor rotates the propeller 2, propelling the hull 1 forward. By controlling the rotation of the two drive motors, the hull 1 can move forward, backward, and turn. When the hull 1 reaches the detection point, the winding motor drives the winding wheel 4 to unwind the sampling hose 5. The sampling head 3 moves downward under gravity. When the sampling head 3 reaches the sampling depth, the electromagnet is energized, creating a magnetic attraction between the electromagnets, pulling... The connecting rod 18 moves upward, the spring 19 is compressed and deformed, and the holes on the perforated plate 16 and the perforated plate 15 are aligned. External water enters the housing 13 through the filter screen 14. The water pump draws in water through the sampling hose 5 and then injects it into a sample tube through the outlet pipe 9. The drive motor 12 drives the turntable 7 to rotate, moving the sample tube containing the sample to below the probe. The telescopic rod 11 drives the probe to insert into the sample tube, and the water quality analyzer 10 performs water quality testing. During the sampling process, the sealing cover 8 can seal the top of the sample tube to prevent sample water from splashing inside the hull 1 due to device shaking. If it is necessary to test other water areas, the device is moved to the next water area and the above steps are repeated. After the test is completed, the user retrieves the device, drains the water from the sampling head 3 and the sampling hose 5, and then the electromagnet is de-energized. The spring 19 pushes the connecting rod 18 downward, and the perforated plate 16 and the perforated plate 15 are misaligned to seal the housing 13. The sealing cover 8 is then removed, the sample tube is taken out, cleaned, and put back.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
