[0015] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0016] Please refer to the attached Figures 1 to 4The present application provides an unmanned boat for collecting water quality around a marine construction project, comprising a front hull 1, a rear hull 2, a first connecting rope 3 and a second connecting rope 4, the front hull 1 and the rear hull 2 ​​are connected in series front and back, the tail of the front hull 1 is provided with a circular groove 5, the head of the rear hull 2 ​​is provided with a circular protrusion 6 that cooperates with the circular groove 5, one end of the first connecting rope 3 and the second connecting rope 4 are connected to the two sides of the circular groove 5 at the tail of the front hull 1, the other ends of the first connecting rope 3 and the second connecting rope 4 are connected to the winding mechanism 7 located on the rear hull 2, the first connecting rope 3 and the second connecting rope 4 have a certain ductility, the rear hull 2 ​​and the front hull 1 are provided with a sensor 8 for detecting water quality, the rear hull 2 ​​is provided with a water storage tank 32 connected to the outside through a pipeline 9, the water storage tank 32 is connected to the air pressure regulating device 10, the rear hull 2 ​​is provided with a first motor 11, the first motor 11 is provided with a screw shaft 12 and a water-pushing blade 13 arranged on the screw shaft 12.

[0017] When the first motor 11 of the rear hull 2 ​​is working, it drives the screw shaft 12 and the water-pushing blades 13 to work. When the water-pushing blades 13 rotate forward, they generate forward thrust, pushing the unmanned boat forward. When the unmanned boat needs to turn, the winding mechanism 7 is used to drive the release or reeling of the first connecting rope 3 and the second connecting rope 4 to adjust the angle between the front hull 1 and the rear hull 2. For example, when the first connecting rope 3 is reeled in and the second connecting rope 4 is released, the front hull 1 tilts toward one side of the first connecting rope 3, and vice versa. When the front hull 1 tilts, the course of the unmanned boat will deflect when the rear hull 2 ​​pushes again. The turning radius of the unmanned boat is small, which is convenient for entering the designated area for water quality detection. The rear hull 2 ​​and the front hull 1 are provided with sensors 8 for detecting water quality, and the water quality detection can be performed using the sensors 8 for detecting water quality.

[0018] The tail of the front hull 1 of the present invention is provided with a circular groove 5, and the head of the rear hull 2 ​​is provided with a circular protrusion 6 that matches the circular groove 5, so as to facilitate the adjustment of the angle between the front hull 1 and the rear hull 2.

[0019] After reaching the designated position, the front hull 1 and the rear hull 2 ​​are adjusted to be located on the same straight line, and the first connecting rope 3 and the second connecting rope 4 are released, and the front hull 1 and the rear hull 2 ​​are separated. Then, the air pressure regulating device 10 is used to extract the gas in the water storage tank 32. When the air pressure in the water storage tank 32 is reduced, the external water enters the water storage tank 32 from the pipeline 9, so that the rear hull 2 ​​is gradually immersed in the water. Then, the first motor 11 can be used to drive the screw shaft 12 and the water-pushing blade 13 provided on the screw shaft 12 to reverse, and the water-pushing blade 13 is used to drive the rear hull 2 ​​to move underwater quickly. After the rear hull 2 ​​moves to the bottom of the water, the screw shaft 12 rotates into the silt at the bottom of the water, thereby fixing the rear hull 2 ​​underwater. The rear hull 2 ​​can collect water quality data at the bottom of the water, and the front hull 1 can collect water quality data on the surface of the water, thereby increasing the range of data collection. At the same time, the rear hull 2 ​​plays a fixing role, which can enable the unmanned boat to collect water quality data at a fixed position. When encountering strong winds, the front hull 1 can be put underwater to prevent the unmanned boat from being damaged by wind.

[0020] Specifically, the water storage tank 32 is a conical structure, the inner diameter of the side of the water storage tank 32 close to the stern is larger than the inner diameter of the side away from the stern, and the pipe 9 connects the side of the water storage tank 32 close to the stern. After the water enters the water storage tank 32, it gathers on the side of the water storage tank 32 close to the stern, causing the stern to tilt downward due to gravity, and finally the tail of the rear hull 2 ​​faces downward, and the water-throwing blades 13 at the tail of the rear hull 2 ​​push back, so that the tail of the rear hull 2 ​​moves in the direction and is finally fixed underwater.

[0021] Specifically, the winding mechanism 7 includes a first winding drum 14, a second winding drum 15, a first bevel gear 16, a second bevel gear 17, a third bevel gear 18, a rotating ring 19, a connecting rod 20, a buoyancy block 21 and a second motor 22. The first winding drum 14 or the second winding drum 15 is connected to the second motor 22. The first winding drum 14 and the second winding drum 15 are rotatably installed on the rear hull 2. The first winding drum 14 is fixedly connected to the first bevel gear 16, and the second winding drum 15 is fixedly connected to the second bevel gear 17. The first bevel gear 16 and the second bevel gear 17 are meshed with the third bevel gear 18. The third bevel gear 18 is rotatably connected to the rotating ring 19, and the rotating ring 19 is rotatably connected to the rear hull 2. The middle part of the connecting rod 20 is rotatably connected to the rear hull 2, the end of the connecting rod 20 is connected to the buoyancy block 21, and the head end is provided with a brake pad 23 for braking the rotating ring 19. Taking the connection between the second motor 22 and the first cable reel 14 as an example, when the second motor 22 rotates, it drives the first cable reel 14 to rotate. When the rotating ring 19 is not braked, the rotating ring 19 can rotate freely. The resistance of the relative rotation of the first bevel gear 16, the second bevel gear 17 and the third bevel gear 18 is greater than the resistance of the rotating ring 19. At this time, when the second motor 22 rotates, it drives the first cable reel 14 and the second cable reel 15 to rotate synchronously. At the same time, the first bevel gear 16, the second bevel gear 17 and the third bevel gear 18 are relatively stationary and rotate synchronously with the first cable reel 14 and the second cable reel 15. When the rotating ring 19 is braked, when the first bevel gear 16 rotates, it drives the second bevel gear 17 to rotate through the third bevel gear 18. At this time, the first bevel gear 16 and the second bevel gear 17 rotate in opposite directions. Therefore, when the second motor 22 rotates, it drives the first cable reel 14 and the second cable reel 15 to rotate in different directions.

[0022] When the water storage tank 32 is not filled with water, the buoyancy block 21 moves downward due to the action of gravity, thereby driving the end of the connecting rod 20 to move downward, and the head end of the connecting rod 20 moves upward, thereby driving the brake pad 23 to brake the rotating ring 19. At this time, the second motor 22 drives the first winding drum 14 to rotate forward when it rotates forward, and drives the second winding drum 15 to rotate reversely. When the second motor 22 reverses, it drives the first winding drum 14 to rotate reversely, and drives the second winding drum 15 to rotate forward. At this time, the tilt angle of the front hull 1 is adjusted by the forward rotation of the second motor 22, thereby controlling the steering of the unmanned boat.

[0023] When the water storage tank 32 is filled with water, the buoyancy block 21 floats upward due to the buoyancy, thereby driving the end of the connecting rod 20 to move upward, and the head end of the connecting rod 20 to move downward, thereby driving the brake pad 23 to release the brake on the rotating ring 19. When the rotating ring 19 is not braked, the second motor 22 drives the first winding drum 14 and the second winding drum 15 to rotate forward when the second motor 22 rotates forward, and drives the first winding drum 14 and the second winding drum 15 to rotate backward when the second motor 22 rotates backward, thereby releasing or reeling the first connecting rope 14 and the second connecting rope 15, and separating or combining the front hull 1 and the rear hull 2 ​​from each other.

[0024] Optionally, the centers of the circular groove 5 and the circular protrusion 6, the connection point between the first connecting rope 14 and the front hull 1, and the connection point between the second connecting rope 15 and the front hull 1 are located on the same straight line, and the side and bottom of the front hull 1 are provided with a first guide plate, and the side of the rear hull 2 ​​is provided with a second guide plate, which facilitates the control of the steering of the hull and improves the stability of the unmanned boat.

[0025] Specifically, the buoyancy block 21 is located in the water storage tank 32 near one end of the pipe 9. After the water enters the water storage tank 32, a faster response can be made.

[0026] Specifically, the first bevel gear 16 is provided with a first magnet 24, the magnetic pole direction of the first magnet 24 is perpendicular to the rotation axis of the first bevel gear 16, the second bevel gear 17 is provided with a second magnet 25, the magnetic pole direction of the second magnet 25 is perpendicular to the rotation axis of the second bevel gear 17, and the first magnet 24 and the second magnet 25 attract each other. The first magnet 24 and the second magnet 25 attract each other, and when the first bevel gear 16 and the second bevel gear 17 rotate relatively, it is necessary to overcome the magnetic force of the first magnet 24 and the second magnet 25 to ensure that the resistance to the relative rotation of the first bevel gear 16, the second bevel gear 17 and the third bevel gear 18 is greater than the resistance to the rotation of the rotating ring 19.

[0027] Specifically, the first magnet 24 and the second magnet 25 are bar magnets, which can stably generate mutual magnetic forces.

[0028] Specifically, the outer edge of the rotating ring 19 is provided with a first protruding tooth 26, and the brake pad 23 is provided with a second protruding tooth 27 that cooperates with the first protruding tooth 26. The first protruding tooth 26 and the second protruding tooth 27 cooperate with each other to improve the braking effect.

[0029] Specifically, the air pressure regulating device 10 includes an air tank 28, an air pipe 29, an air pump 30 and an electromagnetic valve 31, and the air tank 28, the air pipe 29, the air pump 30, the electromagnetic valve 31 and the water storage tank 32 are connected in sequence. When the electromagnetic valve 31 is opened, the gas in the air tank 28 and the water storage tank 32 can circulate with each other through the air pipe 29, and the air pump 30 drives the gas to flow in the air pipe 29. When the gas in the air tank 28 flows to the water storage tank 32, the gas discharges the water in the water storage tank 32, which can make the rear hull 2 ​​float. When the gas in the water storage tank 32 is pumped into the air tank 28, the water storage tank 32 forms a negative pressure, and the external water enters the water storage tank 32 from the pipeline 9, which can make the hull sink. After the water level in the water storage tank 32 reaches the requirement, the electromagnetic valve 31 can be used to close the air pipe 29 to cut off the gas flow between the air tank 28 and the water storage tank 32.

[0030] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
