[0017] The beneficial effects obtained by the present invention with the above structure are as follows:

[0018] 1. This application uses the method of moving on the water surface to detect water at different positions, which is convenient for rapid deployment and monitoring in different waters. When moving, the water flow drives the transmission impeller to rotate, and the water flow can also form a spiral water flow through the guidance of the spiral guide groove to clean the blocked garbage. The transmission impeller drives the driving gear to rotate, and the gear meshing method is used to drive the driving gear to drive the transmission gear to rotate, driving the mobile box to take water. When taking water, the lever swings to separate the driving gear from the transmission gear, so that continuous sampling can be achieved, and the water body can be automatically sampled. The principle of generating electrons by electrogenic bacteria decomposing organic matter can accurately detect heavy metal pollutants in the water. When the mobile box moves, it can also compress the air, and discharge the monitored water under water pressure and high-pressure airflow pressure;

[0019] 2. When moving on the water surface, the water flow drives the transmission impeller to rotate, and the bevel gear meshing transmission method is used to drive the driving gear to rotate, reducing the input of external energy;

[0020] 3. The mobile box is driven to move by means of gear transmission, and the taper plate is driven to move by means of lever swing. The transmission gear is separated from the driving gear, and the torsion spring is reset to drive the mobile box to reset, and the lever is reset to reset. The transmission gear is meshed with the driving gear again, and the mobile box is driven to take samples again, and the water body is automatically sampled;

[0021] 4. After the sampling is completed, the water flows into the water tank by mechanical guidance. The anode and the cathode use the principle that electrobacteria decompose organic matter to produce electrons to detect heavy metals in the water. When the mobile box is reset, the air in the return pipe is compressed, and the compressed air enters the water tank. The water pressure and high-pressure airflow push the water baffle to move and discharge the tested water sample. It can also determine whether to collect the water sample as evidence based on the test results. When a voltage peak appears between the anode and the cathode, it is determined that the current water heavy metal content exceeds the standard. When no voltage peak appears between the anode and the cathode, it is determined that the current water heavy metal content does not exceed the standard. BRIEF DESCRIPTION OF THE DRAWINGS

The two ends of the pushing spring 707 are respectively fixedly connected to the top wall of the guide rod 708 and the top wall of the moving box 701.

[0043] As Figures 1-2 and Figure 5As shown, a guide seat 10 is coaxially and fixedly connected to the outer circumferential wall of the water intake pipe 4.

[0045] As Figures 1-2 and Figure 7As shown in the figure, the detection component 8 includes a water storage tank 801, a water baffle 802, a drainage spring 803, a placement seat 804, an anode 805 and a cathode 806. The side wall of the water storage tank 801 is fixedly connected to the inner side wall of the detection tank 2. One side of the water storage tank 801 is open. A connecting pipe 807 is fixedly connected to one side of the water storage tank 801. The water storage tank 801 is communicated with the water intake pipe 4 through the connecting pipe 807. When the baffle 706 cannot block the drain port 709, the drain port 709 is arranged corresponding to the connecting pipe 807. The water in the moving box 701 flows into the water storage tank 801 through the connecting pipe 807. The top wall of the water baffle 802 is slidably connected to the inner top wall of the detection tank 2. The two ends of the drainage spring 803 are respectively fixedly connected to the side wall of the water baffle 802 and the inner side wall of the detection tank 2. When the drainage spring 803 is not stretched, the water baffle 802 blocks the opening on one side of the water storage tank 801. When the moving box 701 approaches the inner top wall of the water intake pipe 4, the moving box 701 compresses the air in the water intake pipe 4 and enters the water storage tank 801 through the connecting pipe 807. When the water baffle 802 is subjected to the water pressure and air pressure in the water storage tank 801, the drainage spring 803 is compressed. A cathode 806 is fixedly connected inside the water storage tank 801. A placement seat 804 is fixedly connected to the inner bottom wall of the detection tank 2. River bottom mud is placed in the placement seat 804. The anode 805 is arranged in the placement seat 804 and the anode 805 is buried in the river bottom mud. The anode 805 is electrically connected to the cathode 806. The anode 805 collects the electrons generated by the electrogenic bacteria decomposing organic matter and transmits them to the cathode 806 through a wire;

[0046] The reaction formula for electrogenic bacteria decomposing organic matter to generate electrons is as follows:

[0047] CH3COO - + 4H2O = 2HCO3 - + 9H + + 8e -

[0048] The cathode 806 is located in the water storage tank 801 and contacts water at the same time, catalyzing the reduction reaction of O2, electrons and H + in the water. Electrons are continuously transferred from the anode 805 to the cathode 806, thus forming an electric current and forming a voltage. Under natural conditions, electrons reach the cathode 806 from the anode 805 and undergo a slow reduction reaction with the dissolved oxygen in the water. The product is water. The reaction formula is as follows:

[0049] O2+ 4H + +4e - = 2H2O

[0050] This reduction reaction proceeds very slowly, so the electrogenic voltage is very weak. When heavy metal wastewater, such as copper (Cu 2+ ), chromium (Cr 6+ ), mercury (Hg2+ ), Tin (Sn 4+ ), Thallium (Tl 3+ ), Arsenic (As 5+ ), etc. When discharged into water bodies, heavy metal pollutants consume the electrons on the surface of the cathode 806. For example, Cu 2+ , Cr 6+ , Hg 2+ undergo the following reduction reactions on the surface of the cathode 806:

[0051] Cu 2+ + 2e - = Cu E ⊖ = 0.342V

[0052] Cr 6+ + 3e - = Cr 3+ E ⊖ = 1.232V

[0053] Hg 2+ + 2e - = Hg E ⊖ = 0.851V

[0054] The standard electrode potential E ⊖ > 0V of heavy metals can obtain the electrons on the surface of the cathode 806 and be reduced. The progress of the reduction reaction accelerates the consumption of the electrons on the surface of the cathode 806, causing an increase in the current between the anode 805 and the cathode 806. According to Ohm's law:

[0055] U = IR

[0056] The increase in current causes an increase in voltage, resulting in a voltage peak;

[0057] Cadmium (Cd 2+ ), Nickel (Ni 2+ ), Zinc (Zn 2+ ), etc. heavy metal pollution was also detected, but no voltage response peak was generated for this. Through XPS detection, no elemental cadmium, nickel, zinc, etc. heavy metals were found on the surface of the cathode 806. This is because the standard electrode potential E 2+ of the reduction reactions of cadmium (Cd 2+ ), nickel (Ni 2+ ), zinc (Zn ⊖ < 0V:

[0058] Cd 2+ + 2e - = Cd E ⊖ = -0.403V

[0059] Ni 2+ + 2e -= Ni E ⊖ = -0.257V

[0060] Zn 2+ + 2e - = Zn E ⊖ = -0.762V

[0061] Therefore, for the standard electrode potential E ⊖ Heavy metal ions with < 0V cannot obtain electrons from the cathode 806 for reduction in the water environment. Without the consumption of electrons on the surface of the cathode 806, no voltage response peak can be caused, which is suitable for monitoring heavy metal species with a standard electrode potential E ⊖ > 0.

The other side wall of the drain base 901 is fixedly connected to the bottom wall of the water storage tank 801, and the drain base 901 is correspondingly arranged with the opening on one side of the water storage tank 801. A collection port penetrates through the drain base 901. The top wall of the baffle 903 is slidably connected to the bottom wall of the drain base 901. The base end of the electric push rod 904 is fixedly connected to the bottom wall of the drain base 901. The electric push rod 904 is electrically connected to the anode 805 and the cathode 806. When the electric push rod 904 is not activated, the baffle 903 blocks the collection port. The inner bottom wall of the water storage tank 801 is fixedly connected with a storage tank 902, and the storage tank 902 is arranged below the collection.

[0063] Connect the floating plate 1 to the hull. At the same time, the floating plate 1 floats on the water surface. When the hull starts, it pulls the floating plate 1 to move. Water flows into the guide pipe 601 and pushes the transmission impeller 602 to rotate. The transmission impeller 602 drives the driving bevel gear 603 to rotate. The driving bevel gear 603 drives the driven bevel gear 604, the driving shaft 605, and the driving gear 606 to rotate. The support spring 513 pushes the support plate 514 and the transmission gear 505. The driving gear 606 meshes with the transmission gear 505, and the driving gear 606 drives the transmission gear 505 to rotate;

[0064] The water also passes through the filter screen on the water inlet 13 to block impurities. The water flow also enters the guide seat 10 and impacts the guide impeller 11, driving the guide impeller 11 to rotate. The guide impeller 11 pushes the water flow towards the outer wall of the water intake pipe 4. The water flow passes through the spiral diversion groove 12 to form a downward spiral water flow, cleaning the impurities blocked by the filter screen on the water inlet 13;

[0065] The driving gear 505 drives the driving rod 503 and the screw rod 506 to rotate. The driving rod 503 drives the torsion spring 511 to tighten. The screw rod 506 drives the moving box 701 to approach the bottom of the water intake pipe 4. When the moving box 701 moves close to the bottom of the water intake pipe 4, water flows through the one-way inlet valve 710 into the moving box 701. When the moving box 701 touches the contact block 507, the contact spring 508 is compressed. The contact block 507 drives the lower push plate 509 to move. The lower push plate 509 contacts the lever 501. The lower push plate 509 drives the lever 501 to swing on the floating plate 1. The lever 501 also drives the upper push plate 510 to move. The lever 501 drives the clamping plate 502 to contact the conical plate 504. The conical plate 504 drives the driving gear 505 to approach the top wall of the water intake pipe 4. The driving gear 505 moves on the driving rod 503. The driving gear 505 drives the support plate 514 to move on the support rod 512. The support spring 513 is compressed, driving the gear 606 to separate from the driving gear 505. Then the torsion spring 511 resets. The torsion spring 511 drives the driving rod 503 and the screw rod 506 to reverse. The screw rod 506 drives the moving box 701 to approach the top wall of the water intake pipe 4;

[0066] When the guide rod 708 contacts the inner top wall of the water intake pipe 4, the push spring 707 is compressed. The guide rod 708 drives the baffle 706 to move. The baffle 706 moves away from the drain port 709. The baffle 706 cannot block the drain port 709. The water in the moving box 701 flows into the water storage tank 801 through the drain port 709 and the connecting pipe 807. The cathode 806 and the anode 805 cooperate to detect heavy metals in the water. When a voltage peak appears, it is determined that the current water has exceeded the heavy metal standard, and the electric push rod 904 is started. The electric push rod 904 drives the blocking plate 903 to move. When no voltage peak appears, it is determined that the current water does not exceed the heavy metal standard, and the electric push rod 904 cannot be started. The push cone 705 moves with the moving box 701. The push cone 705 contacts the upper push plate 510. The upper push plate 510 drives the lever 501 to swing and reset on the floating plate 1. The lever 501 drives the clamping plate 502 to move away from the conical plate 504. The clamping plate 502 disengages from the conical plate 504. The support spring 513 resets. The support spring 513 drives the support plate 514 and the driving gear 505 to move. The driving gear 505 meshes with the driving gear 606. The screw rod 506 drives the moving box 701 to approach the bottom wall of the water intake pipe 4, and water intake is carried out again;

[0067] Re-water intake: When the moving box 701 approaches the top wall of the water intake pipe 4, the top walls of the water storage tank 801 and the inner top wall of the water intake pipe 4 compress the air. The compressed air enters the water storage tank 801 through the connecting pipe 807. The water baffle 802 is subjected to the pressure of the high-pressure air and the water in the water storage tank 801, and the drainage spring 803 stretches. The water in the water storage tank 801 is discharged through the drainage seat 901. When the current between the anode 805 and the cathode 806 increases, the electric push rod 904 is activated. The electric push rod 904 drives the blocking plate 903 to move. The water on the drainage seat 901 is discharged through the collection port and enters the storage tank 902.
