[0020] The surface water quality monitoring device of the present utility model will be described in detail below in conjunction with the accompanying drawings and the detailed implementation mode.
[0021] As Figure 1 shown, the surface water quality monitoring device includes a base 1. The base 1 includes an L-shaped equipment platform 11. One end of the L-shaped equipment platform 11 is fixedly connected to the inner wall of the counterweight box 12, and the other end of the L-shaped equipment platform 11 extends out of the counterweight box 12. A pulling mechanism 3 is provided on the top of the L-shaped equipment platform 11. A connecting seat 13 is fixedly connected to the other end of the L-shaped equipment platform 11. The connecting seat 13 is cooperatively connected to a rotating arm 2. The other end of the rotating arm 2 is connected to a lifting mechanism 5. A floating buoy 6 is provided at the bottom of the lifting mechanism 5. A detection mechanism 7 is provided on the side of the floating buoy 6 away from the lifting mechanism 5.
[0022] The bottom of the L-shaped equipment platform 11 is fixedly connected inside the counterweight box 12. When conducting water quality monitoring, the counterweight box 12 is placed on a ship, and heavy objects such as sandbags or iron blocks are placed in the counterweight box 12. The counterweight box 12 prevents other components from tilting forward and entering the water area. The L-shaped equipment platform 11 is higher than the counterweight box 12. The counterweight box 12 is placed inside the ship, and the L-shaped equipment platform 11 is higher than the ship's side, further enabling the rotating arm 2 to extend out of the hull and into the air above the water surface.
[0023] A connecting seat 13 is provided at the front end of the L-shaped equipment platform 11. A connecting head 22 is provided at the rear end of the rotating arm 2. The connecting head 22 is inserted into the connecting seat 13. The connecting head 22 and the connecting seat 13 are connected by a rotating shaft. The connecting head 22 can rotate around the rotating shaft as the axis, further driving the rotating arm 2 to rotate up and down. A baffle 23 is provided at the other end of the rotating arm 2. A rack 21 is provided on the side wall of the rotating arm 2. The rack 21 is located between the connecting head 22 and the baffle 23.
[0024] The pulling mechanism 3 includes a first motor 32. The output end of the first motor 32 is rotationally connected to a first wire winding shaft 31. The first motor 32 drives the first wire winding shaft 31 to rotate. A support wheel 33 is arranged at the front end of the first wire winding shaft 31. A pull wire 34 is wound around the first wire winding shaft 31. At the top of the L-shaped equipment platform 11 near the connection head 22, a support assembly is fixed. The support assembly includes two support plates 35 arranged parallel and opposite to each other. One end of the two support plates 35 is fixed to the top of the L-shaped equipment platform 11. A support wheel 33 is arranged between the two support plates 35. The support wheel 33 is arranged at the other end of the two support plates 35. The other end of the pull wire 34 passes through the support wheel 33 and is fixed to the top of the rotating arm 2. The top of the support wheel 33 is higher than the top surface of the rotating arm 2. When the rotating arm 2 needs to rotate, the first motor 32 is started to drive the first wire winding shaft 31 to take in and release the pull wire 34. The pull wire 34 pulls the rotating arm 2 to rotate. When the rotating arm 2 is horizontal with the L-shaped equipment platform 11, the front end of the rotating arm 2 is the farthest from the hull. When collecting and monitoring the water sample here, the movement of the hull can be reduced to disturb the water body, and the monitored values are relatively accurate. When the sampling and detection are completed, the rotating arm 2 is lifted upward to be perpendicular to the L-shaped equipment platform 11, and the rotating arm 2 is stored. After storage, the extended width of the monitoring ship is reduced, and the rotating arm 2 is prevented from hitting other ships or other aquatic plants in the unfolded state.

A rectangular notch is opened on the side wall of the sliding block 51 close to the rack 21. The rack 21 is exposed at the rectangular notch of the sliding block 51. A second motor 52 is fixedly connected to the side wall of the sliding block 51. The output end of the second motor 52 is rotationally connected to a gear shaft 53. The gear shaft 53 is arranged in the rectangular notch of the sliding block 51. The gear shaft 53 meshes with the rack 21. When the second motor 52 is started, the second motor 52 drives the gear shaft 53 to rotate, further enabling the sliding block 51 to move back and forth on the rotating arm 2. When the sliding block 51 moves to the front end of the rotating arm 2, sampling can be carried out. After the sliding block 51 moves to the rear of the rotating arm 2, it is convenient for the monitoring personnel to take out the collected water sample. A baffle 23 protrudes from the front end of the rotating arm 2. The baffle 23 prevents the sliding block 51 from detaching from the rotating arm 2. A third motor 54 is arranged at the bottom of the sliding block 51. The output end of the third motor 54 is rotationally connected to a second wire winding shaft 55. A control wire 56 is wound around the second wire winding shaft 55. The second wire winding shaft 55 and the third motor 54 move together with the sliding block 51. The detection mechanism 7 is fixed below the control wire 56. The floating buoy 6 is located between the second wire winding shaft 55 and the detection mechanism 7. The floating buoy 6 is made of a light material. After the detection mechanism 7 is put into the water, the floating buoy 6 floats on the water surface. The floating buoy 6 is used to more clearly display the position of the detection mechanism 7.
[0026] The detection mechanism 7 includes a controller 71. The controller 71 is connected to the control line 56. The bottom of the controller 71 is connected to a sampler 72. On both side walls of the controller 71, a pH meter 73 and a flow velocity meter 74 are respectively connected. When the detection mechanism 7 conducts water quality monitoring and sampling, it extends below the water surface, and the monitoring depth of the detection mechanism 7 is adjusted by retracting and releasing the control line 56.
[0027] The controller 71 is signal-connected to the sampler 72, the pH meter 73, and the flow velocity meter 74. The controller 71 controls the start and stop of the sampler 72, and the controller 71 receives and transmits the measurement data of the pH meter 73 and the flow velocity meter 74.
[0028] The surface water quality monitoring device of the present utility model has the following specific working process:
[0029] Place the surface water quality monitoring device of the present utility model on the sampling boat. Start the first motor 32 to drive the first wire winding shaft 31 to retract and release the pull wire 34. The pull wire 34 pulls the rotating arm 2 to rotate. When reaching the position where sampling is required, start the second motor 52. The second motor 52 drives the gear shaft 53 to rotate, so that the sliding block 51 moves back and forth on the rotating arm 2. When the sliding block 51 moves to the front end of the rotating arm 2, start the third motor 54. The control line 56 extends into the water, and the detection mechanism 7 extends into the water. After monitoring and sampling, after sampling, when the sliding block 51 moves to the rear of the rotating arm 2, the monitoring personnel take out the collected water sample. When the sampling and detection are completed, the rotating arm 2 is lifted upward to be perpendicular to the L-shaped equipment platform 11, and the rotating arm 2 is stored. After storage, the extended width of the monitoring boat is reduced.
