Description

Technical Field

[0001] The utility model relates to the technical field of river water measurement, in particular to an unmanned aerial vehicle measuring ship. Background Art

[0002] The stability of the foundation of the Yellow River flood control project is related to the project safety. In addition to the structure of the dam, the root stone is easily lost and collapsed due to the erosion of the Yellow River flood. The river flow in front of the dam and the depth of the scouring pit are the main factors affecting the safety of the project. For a long time, the front line of flood control has used water probes and lead fish detection to detect the water depth in front of the dam, but these methods are inefficient, unsafe, and have a limited detection range.

[0003] With the development of information technology, automated and unmanned surveying technology has gradually become mainstream, and ships are used in underwater topographic surveying and hydrological data measurement in some water conservancy scenarios.

[0004] When using existing hulls, it is often necessary to set up slides or docks to facilitate the hull to be placed in the water or retrieved from the water. However, when measuring rivers such as the Yellow River, which are turbulent, long, and have random accident locations, it is impossible to adapt to measuring at any location in the river, thereby affecting emergency rescue time; and when the hull enters the water for measurement, underwater weeds often entangle the transducer of the measuring instrument, affecting the measurement results. Utility Model Content

[0005] The utility model provides an unmanned aerial vehicle measuring ship to solve the technical problem in the prior art that the transducer is easily entangled by underwater weeds and thus affects the measuring result.

[0008] The beneficial effect is: when the drone survey ship of the utility model is in use, the drone is first started to transport the hull to the top of the river and put the hull on the water surface. At this time, the drone is turned off and the hull is started to move in the river. During the movement of the hull, the transducer is used to measure the underwater terrain to provide assistance for emergency rescue. During the movement of the hull, the partition block can separate the underwater weeds to both sides, thereby preventing the weeds from contacting the transducer, thereby protecting the safety of the transducer.

[0009] Further, the hull includes a left hull, a right hull, a connecting frame for connecting the left hull and the right hull together, and a main hull provided on the connecting frame. The measuring instrument is provided on the main hull; the drone is provided on the connecting frame; and the partition block is provided on the lower side of the connecting frame.

[0010] Beneficial effects: The structure is simple and convenient for manufacturing and connection.

[0011] Further, there are two pairs of brackets provided on the connecting frame. The two pairs of brackets are respectively disposed on the left and right sides of the main hull, and the two brackets in a pair are arranged at intervals in the front-rear direction. The drone includes four propellers, and the four propellers correspond to the four brackets one by one and the propellers are provided on the corresponding brackets.

[0012] Beneficial effects: Improve the stability of the hull when taking off, and ensure that the hull can land or fall onto the water surface stably.

The left hull 5 and the right hull 6 are symmetrically disposed on the left and right sides of the main hull 8.

[0030] The left hull 5 is provided with a left steering thruster 12 at the front end and a left thruster 13 at the rear end; the right hull 6 is provided with a right steering thruster 14 at the front end and a right thruster 15 at the rear end. The left thruster 13 and the right thruster 15 are used to drive the hull to move forward, and the left steering thruster 12 and the right steering thruster 14 are used to drive the hull to turn.

[0031] At the rear end of the main hull 8, there is also a depth calibration device for measuring the water depth and the elevation of the river bottom. The depth calibration device includes a main control motor 16 provided at the rear end of the main hull 8. A rotating rod 17 is connected to the output shaft of the main control motor 16. A connecting rope 18 is wound around the rotating rod 17, and the other end of the connecting rope 18 is connected to a gravity weight 19 for diving underwater.

[0032] The main hull 8 is also equipped with a Global Navigation Satellite System 10 that is signal-connected to the control terminal to control the hull to travel on the water along a set trajectory, thereby avoiding long-term operation of the hull by staff and preventing repeated measurements, improving the measurement efficiency. At the rear end of the main hull 8, there is also an antenna 21 to improve the stability of signal reception and transmission.

[0033] At the rear end of the main hull 8, there is also a vertical pole. At the upper end of the vertical pole, there is a camera 11 to facilitate the staff to observe the water surface in real time, quickly discover the victims during emergency rescue, and improve the rescue efficiency.

[0034] The main hull 8 is provided with a main cabin. Inside the main cabin, there is a measuring instrument. The measuring instrument includes a transducer 3. During use, the transducer 3 is located below the water surface. The main cabin is provided with a main cabin cover 22 to protect the measuring instrument.

[0035] The left hull 5 is provided with a left cabin 23.

[0037] A partition block 2 is fixedly provided below the connecting frame 7. The partition block 2 is provided with a perforation adapted to the above-mentioned transducer 3, and the transducer 3 is fixedly arranged in the perforation. The partition block 2 is provided with two weed-scraping arc surfaces 4 for separating underwater weeds, thereby preventing the weeds from contacting the transducer 3.

[0038] The unmanned aerial vehicle 1 includes four propellers. The four propellers are arranged in one-to-one correspondence with the four brackets 9, and the propellers are arranged at the upper ends of the corresponding brackets 9.

[0039] The control terminal is signal-connected to the hull, the unmanned aerial vehicle 1, and the measuring instrument to control the operation of the hull, the unmanned aerial vehicle 1, and the measuring instrument.

[0040] In this embodiment, in order to avoid the problems that the combined drone 1 and hull are prone to capsizing in water, and the horizontal stability of the hull and the ability to resist wave height are weak, counterweights are also provided in the left cabin 23 and the right cabin 25, so that 60% of the total weight after the drone 1 and the hull are combined and launched into the water is below the water surface and 40% is above the water surface. Thus, the center of gravity of the combined drone 1 and hull is below the water surface, reducing the risk of capsizing and improving the horizontal stability and the ability to resist surges.

[0041] When the drone 1 hull of the present utility model is in use, first start the drone 1 to transport the hull above the river and place the hull on the water surface. At this time, turn off the drone 1 and start the hull to move in the river. During the movement of the hull, the transducer 3 is used to measure the underwater terrain to assist in emergency rescue. During the movement of the hull, the partition block 2 can separate the underwater weeds to both sides, thus preventing the weeds from contacting the transducer 3 and further protecting the safety of the transducer 3.

[0042] When the drone survey ship of the present utility model is in use, the partition block is used to prevent underwater weeds from contacting the transducer, thereby protecting the transducer and ensuring the measurement accuracy.

[0043] Based on the above description of this specification, those skilled in the art can also understand the following terms used. For example, terms indicating orientation or position relationship such as "upper", "lower", "front", "rear", "left", "right", etc. are based on the orientation or position relationship shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solution of the present utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in the specific orientation.
