Compared with the prior art, the invention has the beneficial effects that:
1. when the water quality monitoring head moves in a river channel, the steering device can change the direction by 360 degrees, the water quality monitoring area is wider, the movement is more convenient, and when the water quality monitoring head stops in a shallow water area, the propelling device can be contracted into the buoy, so that the bottom of the propelling device is prevented from contacting with the bottom of the river to cause grounding, and the efficient operation of water quality monitoring is ensured.
2. According to the invention, the two ends of the propelling cylinder are respectively fixed with the filter screen, impurities in a river channel can be prevented from entering the propelling cylinder through the filter screens to damage the propeller, the bottom of the screw rod is fixed with the limiting plate, the diameter of the limiting plate is smaller than the inner diameter of the telescopic cylinder, and the driving block can be prevented from being separated from the screw rod through the limiting plate. The outside of water quality monitoring head is equipped with the protection casing, and the protection casing is fixed with the bottom of flotation pontoon, can prevent through the protection casing that impurity in the water from causing the pollution to water quality monitoring head.
3. According to the invention, the precision of the water quality monitoring data can be improved through the precision device. An annular column air bag is arranged between the water quality monitoring head and the protective cover, and the air in the air bag can enter the annular column air bag by driving the air cylinder to push and press the air bag downwards. If aerify in the river course, can arrange the water between water quality monitoring head and the protection casing at the annular post gasbag of inflation in-process, the annular post gasbag that is full of gas can fill up the space between water quality monitoring head and the protection casing, and the inboard of annular post gasbag can be hugged closely with water quality monitoring head, and the outside of annular post gasbag can be hugged closely with the protection casing is inboard to separate the water in water quality monitoring head and the river course. Therefore, when the water quality monitoring device moves to a monitoring area in a river channel, the water cannot contact with the water in the river channel, and only when the water quality monitoring device moves to the area needing water quality monitoring, the driving cylinder retracts upwards to enable the gas in the annular column air bag to return to the inflatable air bag, and along with the air elimination of the annular column air bag, the water in the river channel can enter the protective cover to contact with the water quality monitoring head, so that the water quality can be monitored. Therefore, the water quality monitoring head is in contact with water in the river channel when moving to the monitoring area in the river channel, and only the water quality monitoring area is in contact with the water in the river channel for monitoring, so that the monitored data can be more accurate. Because the protection casing can obstruct some impurity and the contact of water quality monitoring head, but some minute impurity still can get into the interior contaminated water quality monitoring head of protection casing when water quality monitoring head removes to the monitoring area to influence the precision of water quality monitoring data. Thereby accurate device just can avoid minute impurity to pollute the precision that water quality monitoring data was improved to the water quality monitoring head.
4. The top of annular post gasbag is connected with first magnet, and the bottom of annular post gasbag is connected with the second magnet, and first magnet and second magnet are the permanent magnet. The magnetic pole of the face of the first magnet that is attached to the toroidal column envelope is different from the magnetic pole of the face of the second magnet that is attached to the toroidal column envelope. The arrangement is that when the driving cylinder pushes downwards, the gas in the inflatable air bag is pressed into the annular column air bag, the first magnet and the second magnet which attract each other can be slowly separated until the first magnet and the second magnet lose the attraction force and the annular column air bag is full, so that the water quality monitoring head and the water in the river channel are separated. When driving actuating cylinder and upwards retracting, when gas among the annular post gasbag got back to in the gasbag of aerifing, water in the river course can get into the protection casing through the hole on the protection casing in, the opposite face of first magnet and second magnet can be because the magnetic pole difference produces mutual appeal to accelerate gas among the annular post gasbag to get back to the speed in the gasbag of aerifing, water among the river course also can get into the protection casing through the hole on the protection casing faster and contact with water quality monitoring head, thereby improve water quality monitoring's efficiency.
5. The first magnet and the second magnet are electromagnets. Set up like this and before driving actuating cylinder bulldozes downwards, through to first magnet and second magnet outage, let first magnet and second magnet lose magnetism, reduce the resistance that the gas in the gas bag of inflating is impressed in the annular post gasbag. When driving actuating cylinder and upwards retracting, when gas in the annular post gasbag got back to in the gasbag of aerifing, water in the river course can get into the protection casing through the hole on the protection casing in, through circular telegram to first magnet and second magnet, the opposite face of first magnet and second magnet can be because the magnetic pole difference produces mutual appeal, thereby accelerate gas in the annular post gasbag to get back to the speed in the gasbag of aerifing, water in the river course also can get into the protection casing through the hole on the protection casing more fast and contact with water quality monitoring head, thereby improve water quality monitoring's efficiency.
6. The first magnet and the second magnet are electromagnets. The direction of the magnetic poles can be controlled by changing the direction of the current, when the annular column air bag is inflated, the magnetic poles of the opposite surfaces of the first magnet and the second magnet are the same by changing the direction of the current, and the first magnet and the second magnet can generate mutual repulsive force, so that the pressure of water can be reduced, the inflation speed is increased, and the air in the annular column air bag can be filled as soon as possible. When the annular column air bag is deflated, the magnetic poles of the opposite surfaces of the first magnet and the second magnet are different by changing the direction of current, and the first magnet and the second magnet can generate mutual attraction, so that the deflation speed can be accelerated, and the efficiency of water quality monitoring is improved.

The first magnet 46 and the second magnet 47 are controlled by the controller 40 to be turned on, off, or change the direction of the current.
The working principle is as follows:
1. when the water quality monitoring head 4 moves in a river channel, the steering device 6 can change the direction by 0 degree, the water quality monitoring area is wider, the movement is more convenient, and when the water quality monitoring head stops in a shallow water area through the telescopic device 7, the propelling device 8 can be contracted into the buoy 1, so that the grounding caused by the contact of the bottom of the propelling device 8 and the river bottom is prevented, and the high-efficiency operation of the water quality monitoring work is ensured.
2. According to the invention, the two ends of the propelling cylinder 31 are respectively fixed with the filter screen 41, impurities in a river channel can be prevented from entering the propelling cylinder 31 through the filter screens 41 to damage the propeller 36, the bottom of the screw rod 17 is fixed with the limiting plate 22, the diameter of the limiting plate 22 is smaller than the inner diameter of the telescopic cylinder 14, and the driving block 15 can be prevented from being separated from the screw rod 17 through the limiting plate 22. The outer side of the water quality monitoring head is provided with a protective cover 42, the protective cover 42 is fixed with the bottom of the float 1, and the water quality monitoring head 4 can be prevented from being polluted by impurities in water through the protective cover 42.
3. The precision of the water quality measurement can be improved through the precision device 43. An annular column air bag 45 is arranged between the water quality monitoring head and the protective cover 42, and the air in the inflatable air bag 51 enters the annular column air bag 45 by driving the air cylinder 50 to push the inflatable air bag 51 downwards. If aerify in the river course, the water between water quality monitoring head and the protection casing 42 can be arranged to annular post gasbag 45 in the inflation process, and the annular post gasbag 45 that is full of gas can fill up the space between water quality monitoring head and the protection casing 42, and the inboard of annular post gasbag 45 can be hugged closely with water quality monitoring head, and the outside of annular post gasbag 45 can be hugged closely with protection casing 42 is inboard to separate the water in water quality monitoring head and the river course. Therefore, when the water quality monitoring device moves to a monitoring area in a river channel, the water in the river channel cannot be contacted, only when the water quality monitoring device moves to the area needing to monitor the water quality, the driving cylinder 50 retracts upwards to enable the gas in the annular column air bag 45 to return to the inflatable air bag 51, and along with the air elimination of the annular column air bag 45, the water in the river channel can enter the protective cover 42 to be contacted with the water quality monitoring head, so that the water quality can be monitored. Therefore, the water quality monitoring head is in contact with water in the river channel when moving to the monitoring area in the river channel, and only the water quality monitoring area is in contact with the water in the river channel for monitoring, so that the monitored data can be more accurate. Although the protective cover 42 can prevent some impurities from contacting the water quality monitoring head, some tiny impurities still enter the protective cover 42 to pollute the water quality monitoring head 4 when the water quality monitoring head moves, so that the accuracy of water quality monitoring data is influenced. Thereby accurate device 43 just can avoid minute impurity to pollute the precision that water quality monitoring data was improved to the water quality monitoring head.
4. The top of the annular column air bag 45 is connected with a first magnet 46, the bottom of the annular column air bag 45 is connected with a second magnet 47, and the first magnet 46 and the second magnet 47 are permanent magnets. The magnetic poles of the face of the first magnet 46 that is attached to the annular column bladder 45 and the face of the second magnet 47 that is attached to the annular column bladder 45 are different. This arrangement is such that when the drive cylinder 50 is pushed downwardly and the gas in the inflatable bladder 51 is forced into the annular column bladder 45, the first and second magnets 46, 47, which are attracted to each other, will slowly separate until the first and second magnets 46, 47 lose their attraction to each other and the annular column bladder 45 is full, thereby isolating the water quality monitoring head from the water in the waterway. When the driving cylinder 50 retracts upwards, and the gas in the annular column air bag 45 returns to the inflatable air bag 51, the water in the river channel can enter the protective cover 42 through the holes 52 on the protective cover 42, the opposite surfaces of the first magnet 46 and the second magnet 47 can generate mutual attraction force due to different magnetic poles, so that the speed of the gas in the annular column air bag 45 returning to the inflatable air bag 51 is increased, the water in the river channel can also enter the protective cover 42 through the holes 52 on the protective cover 42 more quickly to be contacted with a water quality monitoring head, and the water quality monitoring efficiency is improved.
5. The first magnet 46 and the second magnet 47 are electromagnets. Thus, by deenergizing the first magnet 46 and the second magnet 47 before the drive cylinder 50 is pushed downward, the first magnet 46 and the second magnet 47 are demagnetized, and the resistance to the gas in the inflatable air bag 51 being pushed into the annular pillar air bag 45 is reduced. When the driving cylinder 50 retracts upwards, and the gas in the annular column air bag 45 returns to the inflatable air bag 51, the water in the river channel can enter the protective cover 42 through the holes 52 in the protective cover 42, the first magnet 46 and the second magnet 47 are electrified, the opposite surfaces of the first magnet 46 and the second magnet 47 can generate mutual attraction force due to different magnetic poles, so that the speed of the gas in the annular column air bag 45 returning to the inflatable air bag 51 is increased, the water in the river channel can also enter the protective cover 42 through the holes 52 in the protective cover 42 more quickly to be contacted with a water quality monitoring head, and the water quality monitoring efficiency is improved.
6. The first magnet 46 and the second magnet 47 are electromagnets. The direction of the magnetic poles can also be controlled by changing the direction of the current, when the annular column air bag 45 is inflated, the magnetic poles of the opposite surfaces of the first magnet 46 and the second magnet 47 are the same by changing the direction of the current, and the first magnet 46 and the second magnet 47 can generate mutual repulsive force, so that the water pressure can be reduced, the inflation speed can be increased, and the air in the annular column air bag 45 can be filled as soon as possible. When the annular column air bag 45 is deflated, the magnetic poles of the opposite surfaces of the first magnet 46 and the second magnet 47 are different by changing the direction of current, and the first magnet 46 and the second magnet 47 can generate mutual attraction force, so that the deflation speed can be accelerated, and the efficiency of water quality monitoring is improved.
