[0020] The following further describes the utility model with reference to the drawings and embodiments.

[0021] As Figure 1 shown, a bionic fish-shaped water quality detection device includes a housing.

A driving mechanism 3 for driving the entire device to move forward in the water is provided on the tail housing 2, and a water quality detection mechanism for detecting water quality is provided on the middle housing 1.

[0022] As Figure 2As shown in the figure, the water quality detection mechanism includes a water quality detector 73, a detection box 74, a PLC controller 75, a solenoid valve, a water pipe 77 and a water pump 79. The interior of the middle housing 1 is a sealed cavity. The water quality detection mechanism is located inside the cavity. A partition plate 6 is horizontally arranged inside the cavity. The partition plate 6 is fixedly connected to the inner wall of the cavity. The detection box 74 is fixedly arranged on the partition plate 6. The water quality detector 73 is arranged at the bottom inside the detection box 74. The PLC controller 75 is arranged on the outer wall of the detection box 74. The model of the PLC controller 75 selected is Siemens S7-200. The water pipe 77 is arranged on the side of the detection box 74.

The chroma meter 731 can be used to measure the color in water and is often used to detect the content of substances such as humus, organic matter and metals in water. The model of the chroma meter 731 selected is DS200. The COD meter 732 can be used to measure the chemical oxygen demand in water, that is, the total content of oxidizable substances in water, which is an important indicator for evaluating the degree of water pollution. The model of the COD meter 732 selected is Lianhua Technology COD rapid meter 5B-3C(V8). The pH meter 733 can more accurately monitor the pH value of water samples. The model selected is Leici PHS-3C.

[0024] Liquid level sensors 72 are arranged on both the upper and lower parts of the inner wall of the detection box 74. The model of the liquid level sensor 72 selected is CYW11. The signal output end of the liquid level sensor 72 is electrically connected to the PLC controller 75. The liquid level sensor 72, the water quality detector 73, the PLC controller 75, the solenoid valve and the water pump 79 are all powered by a storage battery arranged inside the cavity.

[0025] When detecting water quality, when the water sample in the detection box 74 submerges the liquid level sensor 72 on the upper part of the inner wall of the detection box 74, at this time, the liquid level sensor 72 converts the monitored signal into an electrical signal and transmits it to the PLC controller 75, and the PLC controller 75 controls the solenoid valve and the water pump 79 to close; after the water is detected by the water quality detector 73, at this time, the PLC controller 75 detects the signal sent by the water quality detector 73, and then it can open the solenoid valve and control the water pump 79 to reverse, and discharge the detected water sample in the detection box 74 through the water pump 79. When the liquid level sensor 72 at the bottom of the inner wall of the detection box 74 monitors that all the water in the detection box 74 has been discharged, the PLC controller 75 controls both the solenoid valve and the water pump 79 to close.

[0026] As Figure 3 shown, the driving mechanism 3 includes a mounting frame 31, an angle adjustment motor, a rotating shaft 32, a U-shaped plate 33, a rotating motor 34, a fish tail rotating member 35, a connecting rod 36 and a flange 37. The tail housing 2 is fixedly connected to the middle housing 1 through a connecting plate 4. The mounting frame 31 is fixed on the connecting plate 4. Both ends of the rotating shaft 32 are movably installed on the mounting frame 31. A first gear is fixedly arranged in the middle of the rotating shaft 32. The angle adjustment motor is fixedly arranged in the middle of the connecting plate 4, and a second gear is fixedly arranged on the output shaft of the angle adjustment motor. The first gear meshes with the second gear. One end of the connecting rod 36 is fixedly connected to the middle of the U-shaped plate 33 through a flange 37. Both ends of the U-shaped plate 33 are respectively fixedly connected to both ends of the rotating shaft 32. The other end of the connecting rod 36 is fixedly provided with a rotating motor 34, and the output shaft of the rotating motor 34 is fixedly connected to the fish tail rotating member 35. The angle adjustment motor and the rotating motor 34 are electrically connected to the PLC controller 75.

[0027] By turning on the rotating motor 34, the rotating motor 34 can drive the fish tail rotating member 35 to rotate, so as to drive the device to move forward in the water; by turning on the angle adjustment motor, since the first gear meshes with the second gear, and both ends of the U-shaped plate 33 are respectively fixedly connected to both ends of the rotating shaft 32, therefore, the rotation of the angle adjustment motor drives the U-shaped plate 33 to rotate around the rotating shaft 32. The rotation of the U-shaped plate 33 can drive the rotating rod, the rotating motor 34, the fish tail rotating member 35 and the connecting rod 36 to rotate, so that the entire tail housing 2 swings like a fish tail. By adjusting the rotation angle of the angle adjustment motor, the swing angle of the entire tail housing 2 can be changed, thereby driving the device to move in different directions.

[0028] Both the angle adjustment motor and the rotating motor 34 are provided with waterproof structures, so that the angle adjustment motor and the rotating motor 34 can operate normally in water.

[0029] The tail housing 2 is made of soft material, so that the entire tail housing 2 can swing like a fish tail, thereby realizing the turning of the entire device in water.

[0030] The water quality detection agency further includes a wireless signal transceiver and a remote controller. The remote controller is held by the user. The wireless signal transceiver is arranged in the cavity and electrically connected to the PLC controller 75. The PLC controller 75 conducts wireless communication with the remote controller through the wireless signal transceiver to achieve remote control.

[0031] When the user stands on the shore, the device can also be remotely controlled through the remote controller. The remote control signal is sent into the PLC controller 75 through the wireless signal transceiver. The PLC controller 75 drives the entire device to swim to the position to be detected by controlling the angle adjustment motor and the rotation motor 34.

[0032] The working principle of the present utility model is as follows: The entire device is placed in the designated water area. The entire device is driven to swim in the water area through the driving mechanism 3 to reach the position to be detected. Then, the solenoid valve is opened, and the PLC controller 75 controls the water pump 79 to rotate forward. The water sample in the water area enters the inside of the detection box 74 through the water pipe 77, so as to detect the water quality through the water quality detector 73. When the liquid level sensor 72 on the upper part of the inner wall of the detection box 74 monitors that the water level entering the detection box 74 exceeds the set specified threshold, at this time, the PLC controller 75 controls both the solenoid valve and the water pump 79 to close. After the water is detected by the water quality detector 73, at this time, the PLC controller 75 detects the signal sent by the water quality detector 73, and then the solenoid valve can be opened and the water pump 79 can be controlled to rotate in reverse to discharge the detected water sample in the detection box 74 through the water pump 79. When the liquid level sensor 72 at the bottom of the inner wall of the detection box 74 monitors that all the water in the detection box 74 has been discharged, the PLC controller 75 controls both the solenoid valve and the water pump 79 to close; then, the entire device is driven to swim in the water area through the driving mechanism 3 to reach the next position to be detected, and the above process is continued to be repeated, so as to facilitate the entire device to detect the water samples at different positions in the water area, thereby improving its detection accuracy and precision.
