[0027] See also Figure 1-4 The present invention discloses a water environment monitoring device, which consists of a shell 9 and a rotating rod 12. There are four rotating rods 12 installed on the top of the shell 9. Two opposite rotating rods 12 form a Y-shaped structure with the shell 9. A water quality sensor 7 capable of monitoring the water environment is installed at the bottom of the shell 9.

[0028] The rotating rod 12 is composed of a power rod 13 and an iron shell mesh cover 1. The iron shell mesh cover 1 is installed at one end of the power rod 13. A rubber airbag 2 is installed inside the iron shell mesh cover 1. The power rod 13 is a hollow rod. An exhaust device 4 and an air compression device 3 are installed on the side of the power rod 1 close to the iron shell mesh cover 1. The rubber airbag 2 can be inflated by the air compression device 3, and the rubber airbag 2 can be exhausted by the exhaust device 4. The cooperation of the exhaust device 4 and the air compression device 3 can realize the adjustment of the gas volume inside the rubber airbag 2, thereby realizing the size adjustment of the rubber airbag 2; a gear driving device 5 is installed inside the end of the power rod 13 away from the iron shell mesh cover 1, and the output end of the gear driving device 5 is connected to the driving gear and can drive the driving gear to rotate. The driving gear is connected to the driven gear of the gear rotating device 6. Meshing, the gear rotating device 6 includes a support frame and a driven gear installed on the top of the shell 9, a connecting pipe is installed between the shell 9 and the power rod 13, and the connecting pipe is made of waterproof and retractable material. In order to ensure that the driven gear and the driving gear can always maintain a meshing state, a connecting rod is installed between the driven gear center mounting shaft and the driving gear center mounting shaft, and the two ends of the connecting rod are respectively rotatably connected to the driven gear center mounting shaft and the driving gear center mounting shaft, and there are two connecting rods, which are respectively located on both sides of the driven gear and the driving gear. Since the length of the connecting rod is unchanged and it is located on both sides of the driven gear and the driving gear, it can be ensured that the driven gear and the driving gear are always meshed together and will not fall off, thereby ensuring that when the rotating rod 12 rotates, the rotating rod 12 and the shell 9 are always connected together.

[0029] A PLC remote control module 8 is installed inside the shell 9 near the gear rotating device 6. The PLC remote control module 8 is the control center of the entire device. The PLC remote control module 8 is also coordinated with a handheld controller. The handheld controller can transmit control information to the PLC remote control module 8, and then the entire device is controlled by the PLC remote control module 8; a recovery device 19 is installed on one side of the PLC remote control module 8, and a battery 14 is installed inside the shell 9 on the side of the PLC remote control module 8 away from the gear rotating device 6. The battery 14 is used to supply power to all electrical devices in the monitoring device, and a data storage device 10, a data transmitter 11 and a positioning device 15 are installed on the side of the battery 14 inside the shell 9 away from the PLC remote control module 8.

[0030] A water quality sensor 7 is installed at one end of the shell 9 away from the gear rotating device 6. The probe of the water quality sensor 7 is an alloy probe. The probe extends out of one end of the shell 9 where the water quality sensor 7 is located. A PC plastic protective cover 18 is provided on the shell 9 adjacent to the position where the water quality sensor 7 probe extends out. A signal amplifier 16 is wrapped inside the PC plastic protective cover 18. The signal amplifier 16 is installed on the shell 9 and extends into the interior of the PC plastic protective cover 18. A camera assembly 17 is also installed on the shell 9 on one side of the PC plastic protective cover 18.

[0031] When the device works normally in water, its Y-shaped structure can improve the stability of the device in water and prevent it from turning upside down.

[0032] The four rotating rods 12 are connected to the housing 9 through the cooperation of the gear driving device 5 and the gear rotating device 6. The rotating rods 12 can be closed or spread out along with the gear driving device 5, or one rotating rod 12 can be unfolded while the other rotating rods 12 are not unfolded. Figure 1 Only the four rotating rods 12 are fully deployed. The flexible deployment of the four rotating rods can cope with complex situations in the water. At the same time, the tilting direction of the shell 9 at the bottom of the detection device in the water can also be changed, which is beneficial for further monitoring of the water environment and is also beneficial for monitoring personnel to carry.

[0033] The upper part of the rotating rod 12 is an iron shell mesh cover 1, and a rubber airbag 2 is placed inside the iron shell mesh cover. The rubber airbag 2 can be inflated and deflated according to monitoring requirements. The Archimedes' principle is used to ensure that the monitoring device monitors waters of different depths. At the same time, the external iron shell mesh cover 1 can also effectively protect the rubber airbag 2.

[0034] The PLC remote control module 8 inside the housing 9 can control the flexible rotation of the four rotating rods 12 and the inflation and deflation of the four rubber airbags 2, thereby controlling the extension state of the water environment detection device in the water as well as the hovering, rising and falling in the water.

[0035] If the device fails to signal, the PLC remote control module 8 automatically sends a command to the recovery device 19. The recovery device 19 sends the positioning and fills the four air bags with air, so that the device quickly floats to the surface, which is convenient for monitoring personnel to recover.

[0036] The data storage device 10 inside the housing 9 can store the image data and water quality data in the water, and can also send the image data and water quality data to the data receiving device of the monitoring personnel through the data transmitter 11.

[0037] The PC plastic protective cover 18 at the bottom of the shell 9 can protect the wrapped signal amplifier 16. At the same time, the longer PC plastic protective cover 18 can be the first to contact objects accidentally touched in the water, effectively protecting the camera assembly 17 and the probe of the water quality sensor 7 close to both sides.

[0038] The signal amplifier 16 can greatly improve the signal stability between the monitoring personnel and the device, and prevent the device from malfunctioning due to complex conditions in the water.

[0039] The camera assembly 17 at the bottom of the shell 9 and the probe of the water quality sensor 7 can perform three-dimensional water environment observation and water quality monitoring as the water environment detection device is extended in the water and hovers, rises and falls in the water.

[0040] The PLC remote control module 8 of the device is connected to the handheld controller in the hands of the monitoring personnel, so that the PLC remote control module 8 controls the flexible rotation of the four rotating rods 12 and the inflation and deflation of the rubber airbag 2. At the same time, the unique Y-shaped structure of the device, with the airbag on the upper part and the heavier monitoring device on the lower part, can make the device more stable in the water and not easy to be overturned up and down with the undercurrent in the water. The Archimedes' principle is used to control the shape of the water quality monitoring device in the water as well as the rising, falling and hovering states. On the basis of coping with complex situations in the water, the water environment and water quality at any depth in the water are monitored. The water environment and water quality indicators at different depths can be quickly transmitted to the detection personnel through the data transmitter 11. At the same time, the stability of data transmission is improved through the signal amplifier 16. If the device fails, the recovery device 19 will quickly send the coordinate position of the device, and at the same time make the device quickly float to the surface, which is convenient for the monitoring personnel to recover.

[0041] The unique Y structure of the device can improve the stability of the device in water, avoid the situation where the device is overturned upside down due to undercurrents in the water, or quickly restore to the previous Y shape after overturning. According to Archimedes' principle, the shape, rise, fall and hovering of the water quality monitoring device in the water are controlled by the PLC remote control module 8, which greatly facilitates the detection personnel to monitor the water environment and water quality at different depths of the water area. Due to the unique Y structure of the device, the bottom is most vulnerable to impact, so the PC plastic protective cover 18 can effectively protect the overall device and the camera assembly 17, the probe of the water quality sensor 7, and the signal amplifier 15 is installed inside the extension part, which greatly enhances the signal transmission. The recovery device 19 can prevent the device from being difficult to find after failure, which is conducive to the rapid recovery of the device.
