Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 4 As shown, the river water condition monitoring and inspection device proposed in this embodiment includes a drone 1 and a monitoring camera 101 fixedly installed at the bottom of the drone 1 and a self-cleaning fog and dust removal protection mechanism; wherein the monitoring camera 101 is a network camera and is matched with an external mobile terminal APP, and the drone 1 is used to carry the monitoring camera 101 to fly over the river to carry out water condition monitoring and inspection work.

[0031] Self-cleaning mist and dust removal protection mechanisms include:

[0032] The annular plate 2 is in active contact with the bottom of the UAV 1;

[0033] The screw fastening assembly consists of four sets arranged in a ring and fixed to the bottom of the UAV 1. The annular plate 2 is fitted onto the four sets of screw fastening assemblies. The screw fastening assemblies are used to fix the annular plate 2 and to unlock it when disassembling it.

[0034] Fixed tube 3 is fixedly connected to the bottom of the annular plate 2;

[0035] The convertible rotary internal blowing assembly is rotatably mounted at the bottom end of the fixed tube 3 and fixedly connected to the inner side of the annular plate 2;

[0036] Hair dryer 505 is fixedly installed on the bottom left side of the annular plate 2, and its air outlet is connected and fixed to the convertible rotary drive internal blowing assembly;

[0037] A hemispherical transparent cover 4 is fixedly connected to the bottom of the convertible rotary drive internal blowing assembly and surrounds the monitoring camera 101. The convertible rotary drive internal blowing assembly is used to blow away the anti-condensation fog from the hemispherical transparent cover 4 when the blower 505 is started, and uses air force to convert into rotational force to drive the hemispherical transparent cover 4 to rotate.

[0038] The external blowing dust removal component is connected and fixed to the right side of the fixed pipe 3 and adapted to the right side of the hemispherical transparent cover 4. The external blowing dust removal component is used to discharge the gas inside the hemispherical transparent cover 4 and to use the discharged gas to disperse on the right side to blow dust away from the outside of the rotating hemispherical transparent cover 4.

[0039] Specifically, the fastening assembly includes an internally threaded sleeve 202 fixedly connected to the bottom of the UAV 1. The top of the annular plate 2 has four equally spaced circular locking holes 201, each of which movably engages with its corresponding internally threaded sleeve 202. The bottom of the annular plate 2 has four movable contact points with knob-type bolts 203, the top of which is threaded into the corresponding internally threaded sleeve 202. The internally threaded sleeve 202, the circular locking holes 201, and the knob-type bolts 203 are designed to work together... The ring plate 2 is moved upwards, causing the four circular locking holes 201 to respectively lock onto the corresponding internal threaded sleeves 202. The knob bolts 203 are screwed into the corresponding internal threaded sleeves 202, and the ring plate 2 is pressed and fixed by the four knob bolts 203. When disassembling, the knob bolts 203 are screwed out from the corresponding internal threaded sleeves 202 in the opposite direction, and the ring plate 2 can be moved downwards to separate from the monitoring camera 101, which facilitates the subsequent disassembly and assembly of the ring plate 2 for the maintenance of the monitoring camera 101.

[0040] Furthermore, the convertible rotary internal blowing assembly includes an internal gear ring 504 rotatably mounted at the bottom end of the fixed tube 3. A first bearing is fixedly connected to the top of the internal gear ring 504, and the inner ring of the first bearing is fixedly fitted to the outer side of the fixed tube 3, thus achieving the effect of rotatably mounting the internal gear ring 504. The bottom of the internal gear ring 504 is fixedly connected to the top of the hemispherical transparent cover 4. A rectangular box 5 with an opening on the right side is fixedly mounted on the left inner wall of the annular plate 2. A rotating shaft 501 is rotatably mounted between the top and bottom inner walls of the rectangular box 5. A circular through hole is opened on the bottom inner wall of the rectangular box 5, and a second bearing is fixedly mounted inside the circular through hole and on the top inner wall of the rectangular box 5. The inner ring of the second bearing is fixedly fitted to the outer side of the rotating shaft 501, thus achieving the effect of rotatably mounting the rotating shaft 501. Multiple impeller blades 502 are fixedly connected in an annular pattern at equal intervals to the outer side of the rotating shaft 501. The air outlet of the blower 505 is connected and fixedly connected to the left side of the rectangular box 5 and to the front... The side impeller blades 502 are horizontally aligned, and the bottom end of the rotating shaft 501 extends to the outside of the rectangular box 5 and is fixedly connected to a gear 503. The gear 503 meshes with the inner left side of the internal gear ring 504. The monitoring camera 101 is located inside the internal gear ring 504 and the fixing tube 3. The internal gear ring 504, rectangular box 5, rotating shaft 501, impeller blades 502 and gear 503 work together so that when the blower 505 starts blowing air into the rectangular box 5, the air first blows the front impeller blades 502. 2. Rotation: The impeller blade 502 drives the rotating shaft 501 to rotate, the rotating shaft 501 drives the gear 503 to rotate, the gear 503 drives the internal gear ring 504 meshing with it to rotate, and the internal gear ring 504 drives the hemispherical transparent cover 4 to rotate. As the gas is blown in, the gas is also blown into the fixed tube 3 and the hemispherical transparent cover 4 through the rectangular box 5 to carry out internal blowing anti-condensation work, so as to achieve the effect of blowing the hemispherical transparent cover 4 to clear anti-condensation and drive it to rotate as a whole when the blower 505 is started.

[0041] Furthermore, the external dust removal assembly includes an L-shaped pipe 301 connected and fixed to the right side of the fixed pipe 3. The left end of the L-shaped pipe 301 is configured as a cover-shaped structure. The bottom end of the L-shaped pipe 301 is connected and fixed to an arc-shaped pipe 302 with a bottom sealing structure. The left side of the arc-shaped pipe 302 is connected and fixed to multiple cleaning nozzles 303, all of which are located on the right side of the hemispherical transparent cover 4. The L-shaped pipe 301, arc-shaped pipe 302, and cleaning nozzles 303 work together to blow gas into the fixed pipe 3 and the hemispherical transparent cover 4. The gas blown into the interior is discharged through the L-shaped pipe 301 into the arc-shaped pipe 302, and then blown out to the left through the multiple cleaning nozzles 303 to thoroughly blow away dust from the outside of the rotating hemispherical transparent cover 4, reducing the phenomenon of dust accumulating and covering the outside of the hemispherical transparent cover 4 and affecting the monitoring and inspection work.

[0042] Furthermore, a storage battery located behind the L-shaped tube 301 is fixedly installed on the bottom right side of the annular plate 2, and the blower 505 is electrically connected to the storage battery.

[0043] The usage method of this embodiment is as follows: When using the river water condition monitoring and inspection device, the hemispherical transparent cover 4 is used to protect the monitoring camera 101 on the outside. When the drone 1 carries the monitoring camera 101 to fly over the river to carry out water condition monitoring and inspection work, the blower 505 is turned on. The monitoring camera 101 transmits the recorded image to the external mobile APP so that the staff can understand the river water level and facilitate the staff to remotely know the situation of multiple rivers during the flood season.

[0044] When the blower 505 is started, air is blown into the rectangular box 5. The air first causes the front impeller 502 to rotate, which in turn drives the shaft 501 to rotate. The shaft 501 then drives the gear 503 to rotate, which in turn drives the internal gear ring 504 to rotate. The internal gear ring 504 then drives the hemispherical transparent cover 4 to rotate. As the air is blown in, it also passes through the rectangular box 5 and is blown into the fixed pipe 3 and the hemispherical transparent cover 4 to perform internal air blowing and anti-condensation work. The gas in the part is discharged through the L-shaped tube 301 into the arc-shaped tube 302, and then blown to the left through multiple blowing tube heads 303 to thoroughly blow away dust from the outside of the rotating hemispherical transparent cover 4. This achieves the effect of single-drive integrated cleaning of the inside of the hemispherical transparent cover 4 to prevent condensation and fogging, drive its rotation, and thoroughly blow away dust from its outside. This reduces the phenomenon of dust accumulating and covering the outside of the hemispherical transparent cover 4, affecting the monitoring and inspection work. In addition, the surrounding protection reduces the risk of accidental damage to the monitoring camera 101, making it convenient, safe, and clear to record, monitor, and inspect.

[0045] When it is necessary to remove the obstruction for maintenance of the monitoring camera 101, rotate the four knob bolts 203 in the reverse direction to unscrew them from the corresponding internal threaded sleeves 202, thereby releasing the lock on the annular plate 2. The annular plate 2 can then be removed downwards. The annular plate 2, through the fixing tube 3 and the internal gear ring 504, drives the hemispherical transparent cover 4 downwards to separate from the monitoring camera 101. During installation, the annular plate 2 is clamped upwards onto the four internal threaded sleeves 202 and locked with the four knob bolts 203. This facilitates the subsequent disassembly and assembly of the self-cleaning mist and dust removal protection mechanism.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
